The present investigation aims to evaluate the corrosion characteristics of red mud metal in sodium chloride solution. Metal matrix composites [MMC] are heterogeneous systems containing matrix and reinforcement. Matrix may be alloy or metal or polymer. Reinforcement may be particulate or fiber or whisker. Their physical and mechanical properties can be tailored according to requirement. They are used in automobile, aircraft and marine industries because of their increased corrosion resistance. In this study weight loss corrosion tests and Potestiodynamic polarization studies by using potestiostat are conducted on ZA-27/ Red Mud metal matrix composites in different concentrated sodium chloride solutions. Both matrix and reinforcements are commercially available. Composites are prepared by liquid melt metallurgy technique using vortex method. Composites containing 2, 4 and 6 percent of preheated but uncoated red mud are prepared. Cylindrical specimens and rectangular specimens are machined. Studies are carried out in 0.035%, 0.352% and 3.5% solutions of sodium chloride. In all the tests the composites were less prone to corrosion than the matrix. Hence the composites can be used in the marine environment.

The present report shows the contribution of remote sensing to estimate the volume of water withdrawn from aquifers, for a semi-arid or arid climate, such as that in our study area: the Aquifer System of Spatientrional Sahara. The vegetation area was firstly estimated from a spatial distribution of vegetation indices from the MOD13Q1 product of the MODIS sensor for a period from 2001 to 2011, by an algorithm highlighting the pixels in the red and the infrared. It's, on average, almost constant at 500 km2 for all the years. Furthermore, evapotranspiration was defined spatially and statistically by the MOD16A2 product, on the whole basin for 2011. The statistics are derived from an algorithm ensuring the logic based on the Penman-Monteith equation. These statistics regarding the area of vegetation gave the annual total volume of withdrawn water because this volume is evaporated in the absence of rainfall in the water balance and the depth of the basin does not allow it to vary in the ground's level. There was extraction more than 2,5 billion meters-cube. This means that the enormity of the consumption that is, indeed, a few hundred m3/s. It presents a serious risk of salinity and flow reversal towards the sea. Such a calculation is developed depending on remote sensing elements such as the spatial and temporal resolutions.

In 1960 when China was hit by the Cultural Revolution, Nobody could be said that China will become a big economic power in the world, even surpassing the United States. At the time Chinese fall into chaotic social. Son kills his father, even people who do not follow Mao Zedong would be slain in vile Operate. Even Marskal Peng Teh-Huai the heroman of China Against the USA in the Korean War also beat up severity. China got its renaissance after Mao Zedong's death in 1976, Deng Xiaoping which had been Already three times deported by Mao could bring China as a prayer in World Economics Top power. Because of that, we are sure that the Indonesian reformation seems currently is impossible would come true such as china, so that Pancasila Become Reality and we have democracy Appropriate with the Purposes of the Indonesian. If yesterday the President declared the beginning of the reform of the second hold, it should be done, because it is the Main tools towards the success of the reformation. Hopefully, the Indonesia Leaders Being aware towards the Essential problems of this nation, then increasingly lead the Real straight ON national achievement: A fair and prosperous society based on Pancasila and nation state Republic of Indonesia.

This project deals with the Design of overhead-roadway located at CHALLENGE junction which is a T-junction. Analysis of the existing conditions was carried out to proffers solution to the cause of the problems occurring due to the vehicle competing for space at this intersection. Before carrying out the analysis, a traffic surveys at peak hours, for morning (07:30 to 08:30 am) and afternoon (03:00 to 04:00 pm) were conducted using 15 minutes interval. From the analysis, it was found out that the peak hour factor and flow rate was 0.88 and 1656pcphpl respectively, corresponding to LOS E. This implies that the capacity of the existing road is no longer able to accommodate the traffic flow; hence, overhead roadway was introduced to improve the efficiency of the intersection. The overhead-roadway is of 140 m length with 7 spans, 20 m per span. It consists of a deck slab, longitudinal girders, cross girders, deck beam, pier, foundation and retailing wall. All structural parts for this Flyover were designed using Staad professional software package and Manual method.

Microbes are living organisms that are too small to be seen by the unaided eye, however, they carry out extremely useful processes that cannot be achieved by other physical and chemical means. Alkaline proteases from those microbes are one of the most important hydrolytic group of enzymes that find varied application in various industrial sectors. The aim of this study was focused on isolation of alkaline protease producing bacteria from the study area which have potential application in dehairing of animal skin. Accordingly, 38 alkaliphilic proteolytic bacteria were isolated from the study area (Arba Minch University, Abay campus). Five isolates were screened which had relatively higher clear zone and further examined for dehairing efficiency of their crude enzymes. Hair removal test was undertaken by incubating skin with 15ml of respective crude enzyme at 40oC. Regarding this, one potential isolate was selected and designated as Bacillus sp.AMUa38. Maximum cell growth were observed from this strain at pH 8, 1% salt (NaCl) concentration and 2.5% of inoculum size. Lactose and peptone are potential carbon and nitrogen source for optimum growth of AMUa38. The optimum activity was reached at pH 9 and 500C. The enzyme was stable in the pH range of 7 to 10. The crude enzyme from Bacillus sp. AMUa38 removed hair from goat skin after 6hrs at pH 9 and 400C. These properties suggest that protease from Bacillus sp. AMUa38 could find potential application in leather processing industries which have an economic implication.

Lubambe Copper Mine is located in Chililabombwe, Zambia, and is a joint copper mining venture with three partners that include African Rainbow Minerals (40%), Vale (40%) and the Government of Zambia (20%). The current mining method utilises Longitudinal Room and Pillar Mining (LRP) on 70m long panels strike length. However, these long panels have resulted in unprecedented levels of dilution mainly from the collapse of hanging wall laminated ore shale (OS2) leading to reduced recoveries. Observations made underground show high variability in geological and geotechnical conditions of the rock mass with factors such as weathering on joints, lamina spaced joints and stress changes induced by mining all contributing to weakening and early collapse of the hanging wall. Therefore a study was undertaken to establish the optimal stope strike length of steep ore bodies at Lubambe. The exercise involved the use of Faro Laser Scanner every four stope rings blasted, with time when the scan was performed noted. The spatial coherence of lasers makes them ideal measuring tools in situations where measurements need to be taken in inaccessible areas. Recent advances in laser scanning coupled with the exponential increase in processing power have greatly improved the methods used to estimate stope tonnages extracted from massive inaccessible stopes. The collected data was then used to construct digital three dimensional models of the stope contents. Sections were cut every metre with deformations taken and analysed with respect to time. Deformation rates from the hanging wall was reducing from 0.14t/hr to 0.07t/hr between rings 1 to 8. This reduction was as a result of slot blasting that involved drilling and blasting a number of holes at the same time. Between rings 8 to 25 deformation was constant averaging 0.28t/hr and between rings 26 and 28, a sharp increase in deformation rate was experienced from as low as 0.16t/hr to 6.33t/hr. This sharp increase defines the optimal stope length as 50 m beyond which there is excessive levels of dilution mainly from the hanging wall.

The paper presented one of the application that can be done using smartphones’ camera. Nowadays, forgery is one of the most undetected crimes. With the forensic technology used today, it is still difficult for authorities to compare and define what a real signature is and what a forged signature is. A signature is a legal representation of a person. All transactions are based on a signature. Forgers may use a signature to sign illegal contracts, and withdraw from bank accounts undetected. A signature can also be forged during election periods for repeated voting. Addressing the issues, a signature should always be secure. Signature verification is a reduced problem that still poses a real challenge for researchers. The literature on signature verification is quite extensive and shows two main areas of research, off-line and on-line systems. Off-line systems deal with a static image of the signature, i.e. the result of the action of signing while on-line systems work on the dynamic process of generating the signature, i.e. the action of signing itself. The researchers have found a way to resolve the concerns. A mobile application that integrates the camera to take a picture of a signature, analyzes it, and compares it to other signatures for verification. It will exist to help citizens to be more cautious and aware with issues regarding the signatures. This might also be relevant to help organizations and institutions, such as banks and insurance companies, in verifying signatures that may avoid unwanted transactions and identity theft. Furthermore, this might help the authorities in the never ending battle against crime, especially against forgers and thieves. The project aimed to design and develop a mobile application that integrates the smartphone camera for verifying and comparing signatures for security using the best algorithm possible. As the result of the development, the said smartphone camera application is functional and reliable.

This study aimed at studying the effect of removal of CaCO3 on the texture of the soil profile and that of the control section in some Aridisols of the Sudan. Sixty soil profiles were sampled from Shendi area (latitude16º36' and longitude 33º 48'), River Nile State, Sudan. These soils were analyzed for CaCO3 and 20 of these profiles were found to be of relatively appreciable calcareousness and were, therefore, selected for this study. The following three weighted soil textures were determined: (1) before any removal of the CaCO3 (Texture1); (2) after the removal of CaCO3 (Texture2); (3) after amending the texture by adding the clay sized CaCO3 to the silt fraction (Texture 3). Statistical analysis revealed significant differences among soil separates in the three textures except between clay of T2 and clay of T3 and among sand fractions in the three textures. That was not unexpected because the first texture included both mineral separates plus their equivalent size of CaCO3, the second texture included only the mineral separates in complete absence of CaCO3 while texture 3 was an amended texture. The change in the textural class amounted to 72% of the profiles. Statistical analysis in the weighted texture of the control section revealed that this texture was not affected except in two profiles. That could be attributed to the fact that the clay content of the soils of the study area did not fall at or near the boundary between any two major textural classes used in the Soil Taxonomy. The size of the CaCO3 was found in the order of clay size> silt size >sand size.

Tumour Necrosis Factor (TNF) constitutes a major signature pro-inflammatory cytokine in P.falciparum malaria. Low TNF levels are considered critical in controlling P. falciparum malaria parasitaemia; although high levels of TNF, that mediate a strong inflammatory response which if not well regulated, can lead to immunopathology and severe forms of malaria that may lead to fatalities. The biological activity of TNF can be regulated by soluble Tumour Necrosis Factor Receptors (sTNFRs), sTNFR1 and sTNFR2.Whereas sTNFR1 is constitutively expressed in most tissues sTNFR2 is tightly regulated during an inflammatory response. It was a case control study in age and sex-matched children under 5 years of age with P.falciparum malaria and healthy controls done at Bungoma County Hospital. A sample size of 48 children was derived based on a similar study, it was ultimately comprised of 23 P. falciparum malaria infected children and 24 non-malaria infected controls; they were selected by simple random sampling. Subjects were selected on the basis of parasitaemia, defined based on WHO criteria.The average age across all cohorts was 33 months. In cases on day 1: the average TNF levels were 295.7 pg/ml and sTNFR2 levels were 155.0 pg/ml and on day 3: TNF levels were 200 pg/ml while sTNFR2 levels were 52.1 pg/ml, compared to controls in which TNF levels were 68.2 pg/ml, while, sTNFR2 levels were 27 pg/ml. TNF and sTNFR2 levels were significantly elevated in this study which was indicative of TNF and sTNFR2 utility in distinguishing the various falciparum malaria disease states.

This study examined and developed Inventory Management Strategies (IMS) which could be creatively employed for Productivity Improvement in Equipment Firms (PIEMF) Equipment manufacturing projects suffer from declining productivity and inability to effectively satisfy customized order batch quantity within schedules, budgeted cost and quality specifications due to lack of robust and well defined IMS as well as none code classification of vast number of inventory item. Survey and expost-facto research designs were adopted on the four identified IMS in three EMF. The method used for primary data collection and measurement on four IMS and inventory management parameters was questionnaire modelled into likert five point scale from the target respondents being experts in the subject matter. The secondary data was obtained from the computerised inventory status file of the three equipment manufacturing firms. The methods of primary data analysis and test of research used were Pearsons product moment correlation coefficient and oneway. Analysis of variance (ANOVA) computer software via Statistical Program for Social Science (SPSS) version 17 ABC analysis and classification of materials was used for code categorization of secondary data, also with the aid of Microsoft excel. The results of the analyses highlighted and isolated “A” class of inventory items which are 137 out of 543 for Siemens Nig. Ltd, 154 out of 551 for Dresser-Rand Nig. Ltd and 162 of 551 for Nigerian Engineering Works Ltd. The results of Pearson product moment correlation analysis and test of research hypotheses indicate that Materials Requirements Planning (MRP) followed by Supply Chain Management (SCM) are the most significant IMS as they correlate strongly with PIEMF. The study recommends IMS adoption by code classification of materials; in which MRP or SCM could be deployed for management of “A” class of inventories while classical IMS could be used for management “B” and “C” classes of inventory items.

Batik was incorporated into the Indonesian culture since the Majapahit era. At that time, the royal families of Majapahit Kingdom wore batik clothes for activities such as religious event or kingdom event. Since then, batik was seen as a symbol of nobility. The growth of batik industry, especially in Yogyakarta and Surakarta region, has produced a diverse motive and fabric quality of batik clothes. To help differentiate between these batik clothes, the owner of batik industries created batik labels with intricate design. This study focused on analysing the intricate design and typography found within three batik labels each from Yogyakarta and Surakarta Region to better understand the role of local culture and values in creating the batik label design using vernacular typography and cultural approach. The result shows that the local culture and values symbolically enforced by each keraton (kingdom-like body) and social system in Yogyakarta and Surakarta influenced the batik label design. The high cultured values of Yogyakarta keraton resulted in a more formal and rigid typefaces used in the batik label, giving off a classical feeling. Meanwhile, the more grass rooted values of Surakarta urban culture resulted in a fluid and flowing typefaces, giving off a trendy casual feeling.

Preventive and breakdown maintenance system for a gas compressor plant were analyzed and appraised using established maintenance tools. To determine this, comparative cost benefit analysis of preventive and breakdown maintenance activities on Agbada gas compressor plant of the Shell Petroleum Development Company was carried out. The cost of achieving 20,000 run hours overhaul preventive maintenance with some disused repaired parts was analyzed and compared with the cost of carrying out the same activity with all new parts. Comparative studies showed that carrying out preventive maintenance with repairable parts, which were recovered in the 'as new state', is more cost effective than using all new parts. A cost saving of 14.63% was achieved. The same trend was also observed when the cost benefit analysis was carried out in breakdown maintenance option. This again gave a cost savings of 7.51 % when repaired disused parts were used. The results showed that the rate of return on investment if breakdown maintenance is adopted is 24% as compared to the rate of return 01: 26% that was obtained when preventive maintenance system was used. An NPV of N6,703,491,725.00 and N5,371,346,424.00 were obtained for preventive maintenance and breakdown maintenance respectively. It is therefore observed that preventive maintenance system strategy presented a better NPV over breakdown maintenance.

Blister beetle is a highly movable Coleopteran insect. Adults mainly feed on floral parts while grub exhibits predacious habit which preys on honey bee and eggs of grasshoppers. Management of this beetle in the garden which predominantly contains flowering plants is a serious concern. Application of chemical pesticides is costly comparatively while it leads to environmental hazards. By considering these aspects, the experiment was conducted to evaluate the infestation severity and efficiency of handpicking in both laboratory and field. For damage estimation, two severely affected plants species were selected and assessed in terms of damaging parts in flower and count of beetle while in vitro study was conducted to analyze the feeding preference by introducing the beetles into four different plants species. Four replicates were maintained. Results were analyzed statistically using one-way ANOVA in SPSS. Handpicking was performed every day Morning up to seven days continuously. The results revealed most of the flower parts damaged by this beetle except sepal and ovary. In field level, beetle infestation high in shoe flower and the maximum damage percentage obtained as 54.6% per plant. In vitro study also confirmed that the shoe is highly preferred by this beetle while among the shoe flower species, shoe flower yellow and shoe flower big pink scored 100% damage but shoe flower yellow significantly damaged by this beetle. Handpicking reduced the number of beetles significantly since it was noted that the number beetles were high in some random plants up to three days. After the fourth day, the population was minimized to zero and no further entry observed. These results suggested handpicking is an efficient management practice for this large beetle in the garden level within 0.5 ha.

In water-scarce developing countries, river basins are some of the most valued natural resources, but many are poorly gauged and have incomplete hydrological and climate records. In the recent years, tropical rivers are increasingly becoming erratic, with many hydrologists attributing this variability to combined effects of landscape-specific anthropogenic activities and climate change. Uncertainties about the impacts of climate change compound the challenges attributed to poor and often inconsistent river monitoring data. Under data-scarce conditions and with the increasing land use intensification and urbanization, modelling approaches become a useful tool in planning and management of water resources. In this paper, we review the application and usability of the Soil and Water Assessment Tool (SWAT) model in conventional planning practice in the management of water resources is poorly-gauged tropical watersheds of Kenya. We assess the technical implications of the model in Intergrated Water Resources management (IWRM) and its applicability as a planning and management tool for water resources in the era of climate change.

The perception of water in Indian philosophy is very different. Water and religion are inextricably woven into each other in the form of holy rivers like a composite fabric into Indian lifestyle. The rivers have a special significance in Indian culture and religious practices. With the changing times, there had been a drastic transformation in the very basic definitions of pilgrimage, religious tourism and recreational activities associated with them. The waterfronts; religious or otherwise are invariably associated with the urbanization and socio cultural dimensions. They have come up as multifunctional spaces with a major paradigm shift in their activity patterns and planning principles.

In this study, the parameters affecting the crystallization of sodium chloride from brine were investigated. Taguchi experimental design method was applied to study the most influential controlling parameters such as feed concentration, mixer speed, heating load, and residence time on the crystallization yield of salt. An L9 (34) orthogonal array experimental design, consisting of four parameters, each with three levels, was employed to examine the effect of the simultaneous variation of these parameters as control factors on the mass yield. Statistical analysis of variance (ANOVA) was also used to determine the relationship between the experimental conditions and salt yield levels. The results from the signal-to-noise (S/N) analysis showed that the optimum conditions for maximum crystal yield were achieved when the feed concentration, mixer speed, residence time, and heating load are 0.248 g of NaCl/g of solution, 830 rpm, 50 minutes, and 1400 W, respectively. Moreover, the ANOVA results indicated that the residence time and heating load are the most significant parameters influencing the salt crystal yield with a contribution of 57.11% and 20.07%, respectively. The mixer speed and feed concentration had the smallest effect on the crystal yield with a contribution of 19.55% and 3.3%, respectively.

The Classical Apriori Algorithm (CAA), which is used for finding frequent item sets in Association Rule Mining, consists of two main steps; the join step for generating candidate item sets and the prune step for eliminating candidate item sets that are not frequent. The CAA despite its simplicity has some limitations; the generation of a large number of candidate item sets, the generation of many combinations that never occur in the database as well as the need to perform several full database scans when generating frequent item sets. In this research, a Modified Apriori Algorithm (MAA) is proposed to address the problem of generating many combinations that never occur in the database by using a row-wise combination generation technique. A comparison of the results of the proposed algorithm against the Classical Apriori Algorithm shows that the proposed algorithm is faster and more efficient. The MAA was implemented on transaction databases and the results were compared against results from four (4) other Improved Apriori Algorithms for efficiency. The results of the comparative analysis showed that the MAA was more efficient in terms of execution time than the other Improved Apriori Algorithm.

In this paper, experimental investigations were conducted to demonstrate the effect of natural particles used as a reinforcement material on polyurethane resin. The effect of sunflower husk particles, used as a reinforcement material, on tensile strength, elasticity modulus, and water absorption with different weight fractions (2%, 4%, 6%, 8%, and 10%) and particle grain sizes (<53, <75, and <106 µm) were investigated. The addition of up to 10% sunflower husk as reinforcement materials to polyurethane resin increased the tensile strength and elasticity modulus of the prepared composite material. However, the decrease in reinforcement material grain size led to the increase in tensile strength, elasticity modulus, and water absorption. Therefore results were considered superior in terms of composites containing reinforcement material with <53 µm. Finally, the best result for tensile strength, elasticity modulus, and water absorption was obtained by adding 10% sunflower husk as a reinforcement material to polyurethane resin.

Considered as a country with clean renewable energy resources abundant, but the application of renewable energy technology is still in its early stages and still limited in Vietnam. According to the Ministry of Industry and Trade, the growth rate of energy demand in Vietnam is now double the GDP growth rate. Meanwhile, in developed countries, the ratio is only lower than one. Vietnam's energy consumption is growing, almost five times between 1990 and 2004 (from 4.21 Million tons of oil converted to 19.55 million tons in order), with an annual average increase of 11.7% per year. According to "Vietnam's National Energy Development Strategy to 2020, Vision to 2050," approved by the Prime Minister since 2007, the target of new and renewable energy sources remains at a modest level (about 5% of total primary commercial energy by 2010 and 11% by 2050). Meanwhile, demand for energy is rising rapidly in Vietnam.

This paper presented an optimal sizing technique for an off-grid hybrid system consisting of Small Hydro (SHP) system, Photovoltaic (PV) modules, Battery (BATT) banks and Diesel Generator (DG). The objective cost function (Annualized Cost System) and the Loss of Power Supply Probability (LPSP) were minimized with application of Genetic Algorithm (GA) in order to reduce the Cost of Energy (COE) generation. GA compared to other convectional optimization methods has the ability to attain global optimum easily. The decision variables are the number of small hydro turbines, NSHP, number of solar panels, NPV, number of battery banks, NBATT and the capacity of DG, PDG. The proposed method was applied to a typical rural village, Itapaji-Ekiti in Nigeria. The monthly average solar irradiance data were converted into hourly solar irradiance data for uniformity. Sensitivity analysis was also performed to identify the most important parameter influencing the optimized hybrid system. The optimal sizing result of the HPS is 954 kW of SHP, 290 kW of PV panels, 9500 sets of (600Ah) battery strings and 350 kW of DG. The optimal Loss of Power Supply Probability (LPSP) is 0.0054 and the Renewable Fraction (RF) is 0.62, which is indeed a significant improvement on the environment and comparatively better than any other combinations in the system.

Water is a precious resource, but not everyone is aware of it. More than 1 billion people are missing about 20 to 50 liters of clean water each day to cater for basic needs such as eating and bathing. The phenomenon of oil exploration, ocean shipping and petroleum-contaminated wastes is one of the causes of water pollution. It is estimated that about 1 billion tons of oil are transported by sea each year. Part of this volume, about 0.1 to 0.3%, is thrown into the sea in a relatively legal way: the washing of oil tankers with seawater. The shipwreck is relatively regular, disposal of lubricant, or accidental dropping gasoline. The permeation rate of petroleum is seven times that of water, which will cause the groundwater to become contaminated. About 1.6 million tons of hydrocarbons are discharged by rivers of industrialized nations. From the above causes we see that human consciousness is the main cause of pollution of water environment. Resources are not endless, with the exploitation of an indiscriminate wing, rampant, run for market economy benefits without the appropriate treatment, the water pollution is a certain matter. The importance is inevitable if people are unaware of the importance of water for life, in the near future the resources will be exhausted.

The robot industry has developed along with the increasing the use of robots in industry. This has led to increase the studies on robots. The most important part of these studies is that the robots must be work with minimum tracking trajectory error. But it is not easy for robots to track the desired trajectory because of the external disturbances and parametric uncertainty. Therefore, adaptive and robust controllers are used to decrease tracking error. The aim of this study is to increase the tracking performance of the robot and minimize the trajectory tracking error. For this purpose, adaptive control law for robot manipulator is identified and fuzzy logic controller is applied to find the accurate values for adaptive control parameter. Based on the Lyapunov theory, stability of the uncertain system is guaranteed. In this study, robot parameters are assumed to be unknown. This controller is applied to a robot model and the results of simulations are given. Controller with fuzzy logic and without fuzzy logic are compared with each other. Simulation results show that the fuzzy logic controller has improved the results.

Public spaces especially public parks provide an important avenue for social interaction and points of contact amongst residents and visitors in a neighbourhood. The manner in which people view their park experiences in public space has a lot to tell about the spatial organization and planning of park facilities. Certainly, taking an in-depth study on how these spaces and park facilities are used has shown a substantial variance between the objectives of park planners and user experience. Merely the rate of patronage and usage of these public parks accounts to their success ratings. The inadequate usage of park spaces and park facilities by its intended users, by not optimizing its functions due to the negligence in the adoption of universal design principles in park designs, has led to the continued decline of residents’ interaction and opportunities for contact. Based on mixed methods research approach conducted in the residential area of Karakol and its environs, this research studies the spatial arrangements of the facilities within parks’ in Karakol and the subsequent social vacuum; with the intent of enhancing social interaction and communication amongst residents and visitors of that neighborhood. Quantitative data analysis SPSS was used and results presented in form of tables and charts. Research findings shows that, factors that activate a sense of accomplishment withn the parks are well‑maintained greenery and facilities that can be accessed by all age group; and also the opportunity to make use of these areas for relaxation and sports, and open spaces for social gathering or function.

Snack are ready-made foods that are self-produced or purchased from sellers or merchants. Snack sellers can be found along the roadside, in stalls, cake shops around the crowded places like schools, offices, colleges and so on. The Ministry of Health (2014) states that snack is a given or consumed between two time of meals with an energy value of about 200 Kilocalories and 5 grams of protein. Whereas PMT-US standard (Supplementary Feeding of School Children) requires 200-300 kilocalories and 5-7 grams of protein. Snacks are sold around the school by unsettled and non-resident sellers in the school stalls or canteens. Various snacks are sold as rice noodles, sweet corn, fried tempe tofu, fried foods, meatballs, bread, cracker, potatos, jelly, cooked rice, noodles, cimol, cilok, cireng, biscuits, milk, iced tea, iced juices, etc, (Alfid TA, Retno I, Setho and Yohanes K, Bastianus DR, Anasari M 2013) The BPOM (Food and Drug Supervisory Agency) research in Alfid in 2003) stated that from 9465 samples 80% contain harmful ingredients. Snack also has a contribution in the fulfillment of daily nutrition that is energy amounted to 233.11 ± 28.41 Kcal and protein at 6.21 ± 1.39 gram (Rachmawati HN 2013). This type of research is experimental with cireng manufacture from cassava and fish, cassava cireng , Fish and tapioca and cireng original made from tapioca flour.

Soybean seeds rapidly deteriorate or loss of viability and vigor, especially in stress conditions including by saline. This study was aimed to obtain the best seed viability and vigor of soybean treated by seed priming under salt stress. This study used a randomized completely block design with factorial pattern. First factor was the saline stress of NaCl concentration (C) which consisted of three levels (c0 = 0%, 0.5% = c1, c2 = 1%).Second factor was the treatment of seed priming (P) that consisted of 4 levels (p0 = hydropriming, p1 = osmopriming, p2 = matripriming, p3 = vitamin priming). The experiment was repeated three times. Data collected consisted of: germination capacity, germination rate, hypocotyl and epicotyl length, the weight of seedling, and the electrical conductivity. Data were analyzed by analysis of variance followed by Duncan's multiple range test at 5 percent. The results showed that osmopriming, matripriming, and vitamin priming improved total germination and germination rate of soybean seeds under salinity stress, while seed priming with hydropriming caused significantly the reduction of germination total and germination rate in salinity stress of 1 percent. Increased salinity stress from 0 to 1 percent caused a reduction in hypocotyl and epicotyl length, different with osmopriming, matripriming, and vitamin priming that produced hypocotyl and epicotyl longer than hydropriming. In all seed primings, increased salinity stress from 0 to 1 percent lowered the weight of seedlings, and most drastic reduction of seedling weight occurred in seeds treated with hydropriming. Among seed priming treatments, osmopriming, matripriming, and vitamin priming were more able to reduce membrane leakage compared to hydropriming as indicated by lower electrical conductivity rates contributing the increase in tolerance to salt stress and high in seed viability and vigor.

The pollution reduction of Lake Gerio was investigated using mixed Culture of Bacillus Subtilis and Pseudomonas Alcaligenes and Model expressions were developed to describe the behavior of micro organisms in bioremediation which were compared to some models proposed by some individuals in bioremediation applications. Pazouki proposed model was used to validate the experimental data, to demonstrate the usability of the model in predicting the behavior of micro organisms in an aquatic environment. The model was simulated using MATLAB; the results showed that the concentration of the substrate reduces linearly with time. The experimental data also showed concentration reduction with time but did not effectively fit the model. It was therefore concluded that the model can be used to approximately predict the behavior of the system. Therefore the model needs to be modified for accurate prediction of the behavior of micro organisms in an aquatic system.

The food processing industry is one of the fast-growing sub-sectors in Uganda. The industry, which is majorly composed of medium and small scale firms, depends on the locally developed food processing equipment. Due to lack of effective materials selection practices employed by the equipment manufacturers, the materials normally selected for most designs are not the most appropriate ones hence compromising the quality of the equipment produced. This has not only led to poor quality food products due to contamination but could also turn out health hazardous to the consumers of the food products. This study involved the assessment of the current materials selection and fabrication procedures used by the food processing equipment manufacturers with a view of devising best practices that can be used to improve the quality of the food products processed by the locally fabricated equipment. Results of the study show that, designers’ experience biasness and desire to minimize cost compromise the materials selection procedure. In addition to failing to choose the best material for a given application, most equipment manufacturers are commonly fabricating equipment with inadequate surface finish and improper weldments. This hinders the equipment’s ability to meet food hygiene standards.

Use of advanced design system and micro processed technology enhance the performance of transmission sub- system quality and control electromagnetic waves propagation in space, but at the same time resulting into transmitted waves quality problems for utility. One of the major issues of transmission quality is harmonics in transmission subsystem. Through mandatory regulations, harmonics in the transmission subsystem must be prevented to ensure good propagation quality. In this work, we present the design and characteristics of three types of tested Microstrip Antenna (MA). In the first place, longitudinally magnetized ferrite patch antenna is presented. We can control outside the resonance frequency by changing the tensor permeability which is a function of the magnetization of the ferrite substrate. The wavelength in the ferrite is short as the magnetization becomes stronger. This antenna becomes multi-band, used in transmission subsystems as well as IEEE standard transmission quality. A microstrip antenna ultra-wideband double circular slit fed with a coplanar line CPW is designed, and successful results are demonstrated. The proposed antenna is characterized by simplicity of design and food, a very low cost and a relatively stable radiation pattern in this part of the bandwidth. In the last part, we present simulations under HFSS antenna guide wave empty or filled with metamaterials to periodic square openings. This paper presents a new approach to design Microstrip Antenna for wireless transmission subsystems radiation quality monitoring and analysis considering harmonics. Successful results allow us develop a wide ultra antenna band. This is an innovative approach in telecommunication field in terms of radiated elements which thereby improves waves propagation quality. A case study of microstrip antenna performance is presented which encompasses the effects of harmonics on Antenna waveguide to metamaterial ultra broad- band and double slit ULB patch antenna to find out the solution to be implemented.

Over the last two decades Foreign Direct Investment (FDI) claimed an impressive economic record, as it enables economy to transit from an agrarian to knowledge based economy. This paper focuses on the determinants and impact of FDI in Mauritius using annual time series data from 1975 through 2015. The Vector Error Correction Model (VECM) analysis reveals that macroeconomic variables namely inflation rates and exchange rate are among the major and important factor that affect FDI in Mauritius over this period of time. Exchange rate exhibited negative significant influence on FDI while interest rate affects FDI positively. The study therefore recommends that government should continue to diversify the export and tourism markets, ensure stable macroeconomic policies, implement reforms on doing business, increase its expenditure in the area of infrastructural development and redirect FDI in productive sector of the economy as ways to accelerate the growth of Mauritian economy.

Studies have shown that there is a challenge in protecting both natural resources and livelihoods simultaneously. However, little is known when considering the number of livelihoods strategies affected by the effect of conservation methods. This paper seeks to investigate the outcome of sustainable livelihood diversification by considering the number of strategies affected by eviction on households neighboring the boundaries of the Mau forest in Kenya. It is well understood that double sustainability is achieved when environmental protection of biodiversity is attained and the livelihood of households affected focuses on a pro-poor strategy at the same time. The study employs the Negative Binomial Regression and ANOVA to estimate the effect of being a victim of eviction on the number of alternative livelihood strategies. The results indicate a significant difference in diversification between households that were victims of eviction from non victims. Significantly evicted households dominantly engage in low income earning agricultural activities. The findings suggest that evicted households diversify but depend on forests and agricultural activities as a coping mechanism towards eviction. This information is important to policy makers in assisting to achieve double sustainability by looking at forest eviction conversation and household livelihood adoption needs.

The method of primary processing of coffee is a vital determinant of quality and price. Wet processing method produces higher quality beans but is very labourious. This work outlines the design of a small scale, cost-effective, ergonomic, and easily maintained and operated coffee hulling machine that can improve quality and productivity of green coffee beans. The machine can be constructed from locally available materials at a relatively low cost of about NGN 140,000.00 with cheap running cost. The beaters are made from rubber strip which can deflect when in contact with any obstruction causing little or no stresses on drum members and reducing the risk of damage to both the beans and machine. The machine is portable and detachable which make it fit to be owned by a group of farmers who can move it from one farm to the other, making affordability and running cost easier. The easily affordable and relatively low running cost may be further reduced by the fact that the machine is powered by 3.0 Hp petrol engine, which is suitable for other purposes among the rural dwellers. The eventual construction of the machine will encourage more farmers to go into wet processing of coffee and reduce the foreign exchange hitherto lost to this purpose.

Sugarcane (Saccharum officinarum L) is commercial cash and sweet industrial crop. Considering its importance in the agro-processing industry and its economic contribution to the country’s , the Ethiopian government has planned an ambitious plan to expand the sugarcane cultivation farmland and sugar processing factories in the country. Despite the significant commercial value of this crop, the main production constrain is the availability of healthy quality quantity and safe planting material within short time. The planting materials obtained through conventional methods do not meet the increasing demand for planting and they are poor quality and yielding. Nowadays, unlike the conventional propagation method, micropropagation is the only realistic means of achieving rapid and large scale production of healthy quality planting materials in sugarcane and it is an alternative approach for fast multiplication of a variety in its original form even if its procurement is costly. The use of best alternative in terms of cost, is the key to make developing countries like Ethiopia beneficiary from micropropagation technology. In Ethiopia, a lot of sugarcane tissue culture protocols were developed which help to minimize the current challenges of sugarcane production in the country. Currently sugarcane production in Ethiopia has given due attention, it is also allied with its important potential for an environment-friendly bio-fuel production and generating huge electric power. This review highlights the techniques of plant tissue culture and achievement of sugarcane tissue culture in Ethiopia. The production of sugarcane using conventional propagation and micropropagation technology is delineated. Opportunities for Ethiopia’s Sugar Industry are also highlighted.

Geochemical investigation of koton karfe Oolitic iron ore was carried out in order to provide comprehensive data on the geochemical and mineralogical composition. The investigation involved mineral phase analysis, major elements and grade determination. Result the XRF analysis shows high Iron (Fe2O3) content ranging from 63.46% to 74.38%. Aluminum (Al2O3) and silica (SiO2) contents are also fairly high ranging from 7.60% - 16.85% and 7.81% -18.55% respectively. Phosphorous content ranges from 0.89% - 1.20% and sulfur content between 0.07% - 0.26%. In addition, the ores contain other impurities such as CaO, MgO, TiO2 and MnO which exist in considerable negligible amounts. Petrographic studies revealed that most samples contain Goethite as the major Iron ore mineral with some minor amount of Hematite and Quartz as the gangue mineral. The quality of this ore was compared to generalized world standards and ores from other parts of Nigeria and other nations. This comparison shows that Koton Karfe Oolitic iron ore is of low grade with average grade of 47.43% and contain high percentages of gangue (silicates and Aluminum), impurities and deleterious elements, phosphorous and sulphur which are all above the permissible limit.

We propose in this work to study thermally the decomposition of two Tunisian natural phosphates or carbonated fluorapatite in a range of temperature between ambient and 1000°C. Several techniques were used such as thermo gravimetric analysis, differential scanning calorimetry and Infra-Red Spectroscopy for this mineralogical study. The results showed that after dehydration, decarbonation occurs in two steps. In the first one the maximum decomposition rate appears near 660°C for the sample of phosphate 1 and 770°C for the sample of phosphate 2. In the second one the maximum is about 780°C for phosphate 1 and 810°C for phosphate 2. In addition, it was reported that the first decarbonation translated the kinetics of decomposition of the carbonate ions of the type B associated with a vaccum, while the second decarbonation is related to the thermal decomposition of the entity of CO3F, generated by the decomposition of carbonate ions of type B and A.

This paper presents a laboratory investigation on the early age properties and carbonation of concrete containing Ground Granulated Blast Furnace (GGBS) in an inland environment. Properties of concrete made with GGBS blended cement was characterized in terms of physical and chemical composition at early-age. In addition, the effects of inland exposure condition on the durability performance of companion concrete were also investigated in the medium term. Concrete cubes were made using various concrete mixtures of water-binder ratios (w/b) = 0.40, 0.50, 0.60, 0.75 and binder contents = 300, 350, 400, 450 kg/m3. Concrete cube of 100 mm size were cast and cured in water for 3, 7, or 28 days, then characterized at early-ages in terms of its physical and chemical properties. Companion concrete samples were exposed indoor or outdoors to undergo carbonation under natural environment. At the end of the varying exposure period (6, 12, 18 and 24 months), the concrete cube samples were characterized in terms of carbonation depths. The results of the concrete early-age properties and medium-term durability characterisation were analyzed. The results show that, increased knowledge of concrete materials, concrete early-age properties and its exposure conditions are vital in durability considerations for RC structures.
