This study applied the multi criteria decision analysis to geophysical data acquired to achieve an unbiased integration of geoelectric parameters obtained from the results of the interpretation of the geophysical data in the order of their hydrogeologic importance to consequently produce a groundwater prediction model. The geoelectric parameters which were the coefficient of anisotropy, aquifer resistivity, aquifer thickness, overburden thickness and overburden resistivity were the main subsurface factors controlling the flow and accumulation of groundwater resources in the study area. Each parameter was assigned appropriate weight based on Saaty’s nine-point scale and the weights were normalized through the Analytic Hierarchy Process (AHP). The assigned weights were adjudged to be consistent and unbiased through the attainment of consistency ratio of less than 10%. The groundwater prediction model of the area was produced from the application of the Groundwater Potential Index (GWPI) model equation developed. The prediction model classified the groundwater potential of the study area into very low; very low – low; low – moderate; moderate - high and high - very high classes. The results obtained from this study established that the groundwater prediction model produced from the GWPI obtained from the application of multi criteria decision analysis to subsurface factors is accurate and reliable. It has also proven the ability of the methodology adopted as a good decision making tool in the presence of two or more conflicting criteria. This ability makes it a useful tool that can be adopted in the groundwater prediction domain.

With its total number of users (around 95 million) throughout the world, it is important to determine the views of academics who use Edmodo the leading SLN. Social Networking Sites (SNS) like Face book, MySpace, Cyworld and Bebo, which allow users to build communities and communicate and collaborate with each other, came out one after another and attracted the attentions of millions of people. There are a number of studies showing that SNS can be used successfully as a learning environment. The main purpose of SNS is not the field of education, and they lack some useful tools like library, quiz, assignment capacities, and so on, which are the main components of learning management systems (LMS) like Moodle and Blackboard. Moreover, there could also be lots of inappropriate contents in SNS because they are for general use. Because of the wide acceptance of SNS, educational web sites like Edmodo, Ning, and ValuePulse have emerged, which function pretty much like SNS. In the study carried out with the mixed method, the qualitative and quantitative data were collected with an online questionnaire. The findings obtained were interpreted within the framework of cooperative learning and the theories of “Diffusion of Innovations” and “Uses and Gratifications,” and the related themes were formed in Higher education in KRG.

The admixture modification by adding foaming agent can overcome the problem of high SCC viscosity. The use of foaming agent has double effects on the concrete admixture in which, to meet the characteristic of concrete admixture flow, foaming agent takes a role in increasing the concrete admixture viscosity, and the use of foaming agent can affect the value of concrete compressive strength. However, it is necessary to control the use of foaming agent on the concrete admixture. The decrease of concrete compressive strength using foaming agent from 50 MPa job mix design towards the concrete designed without pozzolan has 42.51 MPa of concrete compressive strength value causing decline to 7.49 MPa. Therefore, to overcome the decrease of concrete compressive strength value used, powder materials in a form of silica fume and foaming agent are added. To determine the ratio of adding additional substances, variations of using silica fume and foaming agent with the percentage of 5%, 10%, and 15% is used. Then, one of the ways to overcome the bad impact of the foaming agent use is by substituting half of the cement with pozzolan in the form of fly-ash and silica fume. The fine grains of these pozzolans can increase the cohesion on the fresh concrete and decrease bleeding. However, the portion of both pozzolans should be in a proper ratio so that it will not decrease the concrete viscosity towards the characteristic of SCC due to the fact that pozzolan can absorb water easily. In this case, the maximum value of concrete compressive strength on silica fume admixture is 58.97 MPa and on fly-ash is 54.90 MPa. However, the pozzolan addition of fly-ash or silica fume admixture has maximal limitation use on concrete admixture. The maximal ratio of pozzolan addition is 10% of the cement weight. Pozzolan addition which is more than 10% can affect the compressive strength and the characteristics of SCC.

Gasoline Direct Injection (GDI) engine has the advantages of improving on pollutants in vehicle exhaust emissions significantly and tendency to reduce fuel consumption because of lean burning mixture. This engine is considered environmental friendly since it emits less toxic gases compared to the traditional carburetted or Port Fuel Injection (PFI) spark ignition engines. The modeling process of GDI engine is basically the same as PFI engine except the location of the fuel injector and also in early injection conditions, the characteristics of the two engines are similar. Although the gasoline (DI) engines are less harmful to the environment due to its high thermal efficiency and good performance in fuel consumption, it has some drawbacks of producing more nitrogen oxides (NOX) at high temperature and soot. In addition, stricter emission standards and regulations require that the two engines should constantly be investigated and optimized in order to obtain desirable results. This paper presents and compares numerical model for soot formation in GDI and PFI engines at various engine running conditions and air-fuel ratios (AFRs). The Feng Tao’s soot formation model is modified to suit gasoline engine conditions and implemented in GT-Power for GDI and PFI engines. The GT-Power code simulates the engine running conditions and evaluates the soot formed with crank angles at different engine speeds from 1000rpm to 6000rpm. The results show that for PFI engines the peak value of soot formed in mole fraction between compression and power strokes decreases as engine speed increases with the peak value of 0.0795 and 0.022 respectively at crank angle close to zero degrees for the stoichiometric air-fuel ratio(AFR) of 11.68. On the other hand, in the GDI engine, the amount of soot formed first increases in its peak values with increasing limiting engine speeds and begins to decrease for engine speeds from 4000rpm to 6000rpm. At the same engine speeds for the two engines, the results show that the peak values of soot formed for PFI is higher than the peak values of GDI engine but the total amount of soot generated in GDI engine is far more than PFI engine. Further analysis in terms of the influence of AFRs on the soot formation for the same engine speed for both PFI and GDI engines shows that increasing the AFR leads to the reduction in the amount of soot formed.

the first electric vehicle (EV) was built between 1832 and 1839; the exact year is not known, in Scotland by Robert Anderson, who created the first crude electric carriage. It was not built until 1895, after A.L. Ryker built an electric tricycle and William Morrison built a six passenger wagon, that America paid attention to the electric vehicle [1]. The electric car is considered superior to the internal-combustion car because it has low sound of its engine. Then do what ensued in the evolution of the two cars on the superiority of the internal combustion car for two reasons. First: excellence in cutting long-distance, and secondly: the low weight of the amount of fuel such as gasoline or diesel fuel for the weight of a heavy battery to cut a reasonable distance. It was on the development of the electric car to wait until this day to catch a drive that run on gasoline. In the 1960s and 1970s electric vehicles reappeared because internal combustion vehicles were creating an unhealthy environment for the people in America at that time.

This project discusses about the study of implementation of Android Application for housing society management. Daily residential life in city areas has important things to deal with housing society management. Our day to day needs such as Water supply, Electricity, Security and many more things which directly or indirectly plays vital role in residential life, come under Housing Society Management. In most of the cases, Society management practices a traditional way of communication. This certainly has some limitations and disadvantages. Daily notices, monthly meetings, cultural events, miscellaneous contacts for daily needs, committee calendar, domestic help, complaint section, high priority communication and many others which may not be conveyed properly in current scenario as most of the things are getting handled manually. It lacks transparency. To overcome the problems occurring due to this time lagging manual system, an automated system needs to be developed. A housing society and its functions are a part of our everyday lives. Members of the managing committee are those who take charge of all the chores involved here. Residents often feel edgy regarding undone jobs and most even lack time to keep track of all these happenings. But, there’s no avoiding the fact that these chores and all the housing society members are inseparable. This project report presents the design and implementation of an Android based society maintenance application. The system also maintains the society maintenance as well as parking, cultural funds, emergency funds and other charges and adds them automatically in individual flat bill. The system needs an administrator to input various flat owner data and billing amounts into it. The rest of the work is done by the system on its own. The system consists of automatic bill generation facility. It calculates various associated costs, adds them up and provides a bill accordingly. The elements of this system comprise of (1) An Android application which will be accessed by both managing committee and residents (2) Database server that will contain information entered by the users as well as generated for the users and (3) Business logic that will interconnect and pass information between the application and the database server.

Abstract The use of artificial intelligence (AI) programs has become widespread in business processes. There is some confusion as to what technology is considered AI. There are several levels or types of AI. When referring to artificial intelligence, it is necessary to define the capabilities of the technology. Businesses use a fundamental form of AI, with limited learning capabilities. The costs of the use and development of AI run the continuum from potential job loss or retraining to danger to human life. There may be aspects of the evolving technology that haven’t yet been considered. AI has the potential to create a better world for humanity. Artificial intelligence will continue to evolve in the future and change the landscape of business. Both individuals and organizations need to prepare for the future by embracing the technology and understanding which shifts are required to be successful in the future.

Morphological studies in semi-arid urbanizing watersheds reveal varying responses that describe rapid channel adjustment often with adverse economic and environmental consequences. This study assessed spatial dimension of Ginzo catchment response to urbanization in Katsina Metropolis, Nigeria. Morphometric parameters were obtained through direct field measurements while degree of urbanization in each of the three segments of the river channel was computed from satellite imagery of Katsina metropolis. Descriptive statistics like mean, standard deviation, coefficient of variation, percentages and line graphs were then used in the analysis of data generated from the field. The study revealed that channel width were lowest at the upstream (11.2m) and highest at the downstream section (28.9m). Moreover, mean channel depth were lowest at the midstream (0.34m), and highest at the downstream section (1.45m) while channel cross-sectional area were lowest at upstream (15.40m2 ) and highest at the midstream (61.55m2 ). The results indicate that channel segments respond differently to different level of urbanization. The study therefore, recommends integration of geomorphic knowledge in urban and water resources policy of Nigeria. These include the use of bio-engineering approach in channel management and review of environmental policies to control channel encroachment.

Abstract— Increasing demand of proteases with specific properties has lead biotechnologists to explore newer sources of proteases. Protease, enzyme that cleavage protein can be produced from microorganism, animal and plant. Several protease derived from plants, have been widely used in many industries. Although many proteases have been isolated from plants, there is no previous study of protease from paddy oats. Paddy oats seed is valuable agricultural commodity in some tropical countries, particularly in Indonesia and paddy oats seed peel is only agricultural waste. The industrial demand of protease enzymes, with appropriate specificity and stability to pH, temperature, metal ions, continues to stimulate the search for new enzyme sources. The aim of this research was to detect and to characterize protease in paddy oats seed peel as well as to evaluate its compatibility as detergent additive. To assess the effect of temperature and pH on protease activity, protease enzyme extract were examined at temperature 10, 20, 30, 40, 50, 60 and 70oC, and pH range from 3 to 9. To evaluate the compatability as detergent additive, used detergent available in the local market. To simulate washing conditions, the detergent was diluted in distilled water up to final concentration of 2 mg.mL-1. The solution was boiled for 10 minutes for the inactivation of their protease enzyme contents already present and cooled. Crude extract of protease was added to the detergent solution. The result showed optimum temperature of protease enzyme extract was 40-55oC; optimum pH 6.5-9.0; and blood stain on the fabric could be removed perfectly by detergent-protease enzyme solution in 95 minutes. This study showed that protease enzyme extracted from paddy oats seed peel hold potential as a new source of protease enzyme for biotechnological applications, in particular as detergent additive. Index Terms— Paddy oats, protease enzyme, plant protease, detergent additive

ABSTRACT Background: around half of all populations in the developing world, living on less than US$2 per person per day (measured by purchasing power parity). The higher levels of productivity facilitate higher average earnings. The more secure standard of living allows them to save and invest in their families’ health, education and wellbeing. The economic well-being of women is often used as an indicator of the overall advancement of a society. Objective: the main objective of this study was to assess the determinant factors of women economic class in Dire Dawa administrative city, Ethiopia. Method: the data were obtained from 602 respondents through face to face interview. Tabular methods of data presentation and inferential analysis, particularly binary logistic regression were applied. Results: economic class is poor, when woman’s purchasing power parity is less than US$1.32 per person per day and is non-poor, greater or equal to US$1.32, from the total 602 women included in the study, 32.39 percent were living under poverty line and the remaining 67.61 percent of them were above poverty line (no-poor) based on the purchasing power parity per person per day. The estimated odds ratio (OR = 1.650) indicates that non-poor women were increased by 1.650 times when a unit change of monthly income in relation to those who are living under poverty line. The log odds of non-poor women those who had a total number of children ranges between 2 and 3 are decreased by -.535. Generally, monthly income, education level, number of children, house ownership, microfinance user, employment status, husband’s monthly income and amount of saving were found as the determinant factors of women’s economic class at 5% level of significance. Conclusions: Education provides women with the knowledge, skills and self-confidence they need to seek out economic opportunities. When women attained higher levels of education, they have opportunities to engage on larger wage earning jobs. The incidence of women poverty was shown to increase with the size of the children. Large family size has significant relationship with much greater risk of women’s poverty. Keywords: Women, Economic class, Binary logistic regression

The study aimed at finding out the effect of soaking of ridged gourd seeds (Luffa acutangula) in papaya’s leaves extract on speeding up the germination of the seeds. Ridged gourd is one kind of vegetables which is favored by societies. The breeding of this plant is through its seeds. The problem is that the outer layer of the seed skin is hard and therefore the seed is in trouble to germinate. Thus the seeds need softening before sowing. One way to soften the hard outer skin of the seeds is by soaking them in papaya’s leaves extract. The papaya’s leaves extract contains papain compound that can function to mince the hard layer of the seed skin. The treatments in the study involve several levels namely, G0: no soaking (control); G1: the soaking in the extract with 400 ml of water for 30 minutes; G2: the soaking in the extract with 500 ml of water for 30 minutes; G3: the soaking in the extract with 600 ml of water for 30 minutes; G4: the soaking in the extract with 400 ml of water for 60 minutes; G5: the soaking in the extract with 500 ml of water for 60 minutes; G6: the soaking in the extract with 600 ml of water for 60 minutes; G7: the soaking in the extract with 400 ml of water for 90 minutes; G8: the soaking in the extract with 500 ml of water for 90 minutes; G9: the soaking in the extract with 600 ml of water for 90 minutes. The study resulted that the soaking of the ridged gourd seeds in the papaya’s leaves extract within 400 ml of water for 30 minutes demonstrated the highest speed of germination signified with longest seedlings and longest roots.

The oil palm husk ash contains of 30-40% K2O, 7%, 9% Cao, and 3% MgO.Besides, it contains 1.200 ppm Fe, 1,00 ppm Mn, 400ppm Zn and 100ppm Cu. The purpose of granting this oil palm husk as is to know its optimum dosages for the ground and of yield peanuts. This study used the randomized group design, with treatment as follows; A0 = without oli palm husk ash; A1= with oil palm husk ash 600kg/ha (120g/plot), A2= 900kg/ha (180g/plot), A3= 1200kg/ha (240g/plot), and A4 =1500kg/ha (300g/plot). The result of the analysis of variance shows that this treatment has real effects of various to the weight of peanut and the peanuts per plot. The highest result is shown in A4 = dosages of 1500kg/ha (300g/plot) with total production of 56.00g. Peanuts are also produced from A4 =dosis 1500kg/ha (300g/plot) with total of 23,15 g. Meanwhile, production of the weight of peanuts per plot from treatment A3 dosages 1200kg/ha (240g/plot) with total of 635,75g. Itis different from the treatment A0 with total of 360,75g. This becouse the nutrients elements contain in the palm husk ash gives optimum nutrients to the plant of ground peanuts. And the most contained element in oil palm husk ash is Kalium (30-40%). The results of this study shows that to obtain the optimum result in planting peanut, it is suggested to take dose of 1200kg/ha (240g/plot) oil palm husk ash to get maximum nutrient in the soil.

Construction materials management process is key to the success of a construction project; however, globally, the problem of material management is a critical issue in the construction industry; especially in the developing economies of which Ghana is no exception. This study sought to identify and assess the material management techniques required for construction firms in the Tamale Metropolis of Ghana. Using empirical data obtained from administering questionnaires to 96 material management personnel in Tamale Metropolis. The data was analyzed using descriptive and inferential statistics such as factor analysis, and Pearson product moment correlation coefficient. The study adopted descriptive quantitative survey approach. Using empirical data obtained from ninety-six administered questionnaires of material managers in Tamale Metropolis; the data was analyzed using descriptive and inferential statistics such as factor analysis, and Pearson product moment correlation coefficient. The study indicated that firms often employed store keepers and security personnel on site; list of materials in project that includes for example (material name, material number and unit price), and provide clear specifications to suppliers. However, they seldom use ICT; and rarely offer training for their workers. The study further revealed that planning and monitoring of material schedule; establishing good business relations with suppliers; the use of security measures on site; use of information communication technology; and also use of competent workers as well as effective training of workers is significant for effective material management on construction site, and has direct effect on construction project delivery success. The study therefore concluded that the more the number of the material management approach adopted on a project, the higher the project delivery success. It was recommended that construction companies should make use of more than one material management technique on construction projects so as to achieve maximum project delivery success.

Quality related in-process inspection/verification is an essential part of quality control in manufacturing. Inspection in manufacturing includes measuring, examining, testing, or gauging one or more characteristics of a product or process and comparing the results with specified requirements to determine whether is the requirements are met for each characteristic by developing an automatic inspection system for inspection of products. Inspection is a process which requires the inspection of each individual unit or component received from a supplier to determine specification and quality compliance. Reliance on attribute visual inspection is nearly universal in the manufacturing industry, in general, to confirm the quality of parts prior to shipment. In this project, a conceptual model is proposed for inspection of visual defects using video processing. The model is capable of inspecting products and effort was made to make it cost efficient. After a number of experiments performed it was found that the system is capable of producing only the accepted parts. Keywords: Inspection, Visual Defects, Video processing.

Traditional Teacher Centered Learning (TCL) and Classroom-Oriented Learning (COL) methods and approaches are fast giving ways to alternative, rapidly evolving, styles in our modern Information Age [24]. English Language Teachings (ESL/TEFL), previously a tutor-centered and classroom-based activity, are similarly following suit as evidenced by the availability of CALL methods and technologies [1] [2] [10], and also by the widespread use of Applications (Apps) implemented in smartphones, tablets and pads as well as laptops. Before appropriately implementing any strategy in our case study, a literature review is done to reach an adequate understanding of the state-of-the-art in terms of technology-assisted ESL / TEFL. Next, an appropriately designed questionnaire was used to ascertain the various technological as well as user-centred factors which may impact upon the efficacy and usefulness of such a plan and strategy. Increasingly, students are dependent upon mobile technology for information gathering and communication . How successful can this be in the context of ESL/TEFL? What can we learn from these factors, and how can we best adapt this technology and resource in the context of the English Language learning experience in Kurdistan Iraq?
