A study of the environmental impacts on the coral resources in the vicinity of the Saint Martin Island, Bangladesh was conducted with a view to making an assessment of the current status of coral resources in the island and identifying major natural and anthropogenic environmental threats to the future sustainability of these resources. It is evident that the coral resources have been reduced significantly, and currently, only 41 coral species are available. The existing environmental condition (assessed by pH, salinity, turbidity and temperature) in the island is not found responsible for the survival of the corals. The study also reveals that the major anthropogenic interventions are responsible for the gradual depletion of the coral resources. The major anthropogenic threats to the coral resources are coral collection and overfishing. In addition, coral extraction is identified as a potential threat to the future integrity of coral communities in the island. Environmental threats from anthropogenic activities related to sedimentation, land erosion and pollution are also the concerns for the coral communities in the island. For the conservation of the coral population, no coral monitoring cell has been established in this island.

Abstract: Mo1.0V0.3Te0.23Nb0.12 mixed metal oxide catalysts were prepared via slurry method followed by microwave irradiation. The pH (1, 3, 5, and 7) of the synthesis solution was shown to affect physicochemical properties of the catalysts. XRD analysis revealed that the monophasic orthorhombic M1 phase Te2M20O57 (M = Mo, V, and Nb) was only developed when pH was 1. This catalyst displayed BET surface area, 18.0 m2/g the highest among other samples after post treatment and suggested the elimination of hexagonal M2 phase. The sample was also highly reducible with reduction temperature coincide very well with the temperature of catalytic reaction. Therefore, this catalyst was also active and selective for anaerobic propane oxidation to acrylic acid.

The instrument of environment is an effort to prevent environmental problems caused by mining activities both in forms and its nature. The aims of the study are to analyze and understanding the essence of environment cost-loading in order to restore the environment from coal mining activities, both when mining taken place and post-mining. The type of research used is a normative-legal research. This research was conducted in the province of South Kalimantan, with the consideration that the South Kalimantan is one of the largest coal-producing Provinces in Indonesia. In addition, the environment cost-loading for investor in coal mining have the same properties in all coal mining sites in Indonesia. The results of the research indicated that the imposition and environment-cost in investment activity in the field of coal mining can be seen from the two approaches, i.e the economic and legal approach. Economic approach is an approach that emphasizes the economic benefits gained by the owner of activities when they comply with the environmental requirements stipulated by laws and environmental regulations. Realizing the importance of environmental cost-loading for the company that manages the coal mining, especially for the utilization of prevention of pollution caused by coal mining activity, it is necessary to develop an institutional guarantee of recovery from the effects of pollution by establishing fund insurance for environmental restoration as a result of pollution. Thus, in order to optimize the implementation of guarantee fund for environmental restoration are specifically utilized for post-mining reclamation, then granting the status of Clean and Clear (C & C) for coal mining investor must be presupposing the proof of guarantee fund has been placed for environmental restoration post-mining.

Streptococcus mutans is a bacterium that plays an important role in the process of caries. These bacteria can produce glucosyltransferase (GTF) enzymes which can change the disaccharide, particularly sucrose into glucan that serves as a medium for the initial attachment of bacteria to the tooth surface and produce acids in the metabolic process which is the beginning of dental caries. Aloe vera is natural materials that has a lot of active substances that contains antibacterial effects. Sodium fluoride is a material commonly used in the prevention of caries, serves to remineralization of the teeth and has anti-bacterial properties. The purpose of this study was to analyze differences in decline in the number of colonies of Streptococcus mutans after in vitro administration of Aloe vera and Sodium Fluoride. This research was conducted using pure experimental research on the media containing artificial saliva, enriched with sucrose and the culture of Streptococcus mutans (ATCC 25 175) was incorporated in it. Samples are given treatments of Sodium Fluoride and Aloe vera extracts to see the difference in the number of bacterial colonies. Statistical analysisuses the t test to see a decrease in the number of colonies of Streptococcus mutans between treatment Aloe vera and Sodium Fluoride. T-test equality of two mean the two populations doesn’t show a significant difference between the decline in the group of Aloe vera and Sodium Fluoride group, with p-value of 0.2144. This study concludes that there is no difference in the decreasing in the number of colonies of Streptococcus mutans significantly after in vitro administration of Aloe vera and Sodium Fluoride.

As yoghurt is a health food, assessment of quality of commercialized yoghurt during storage period in refrigerator is needed. Lack of data on quality parameters of yoghurt brands in Sri Lanka is impediment to consumer health. This study is an attempt to fill that gap by providing data on evaluation of the changes of physico-chemical and microbiological parameters of some plain set yoghurt sold in Matara municipal area of Sri Lanka. Five different brands of plain set yoghurt samples were collected on the basis of consumer preference for the present study. From each brand, fifteen samples were analyzed by means of their physico-chemical (syneresis effect, pH, titratable acidity, total protein content) and microbiological composition (total plate count, total yeast and mould count) by using three replicates of each sample at 4, 7, 14, 21 and 28 days intervals from production date under refrigerated condition (4 C) and compared against local and international standards. All microbiological parameters and total protein content of all plain set yoghurt brands were not within the permissible range for local and international standards. Titratable acidity was only in the permissible range of local standards. All the physico-chemical parameters and microbiological parameters of collected samples were significantly affected by storage period. Good quality yoghurt of physico-chemical and microbiological parameters with hygiene conditions during processing and storage should be encouraged for consumption.

Semiconductor Cadmium selenide (CdSe) Quantum Dots (QDs) were synthesized via colloidal chemistry method at moderately lower growth temperatures. Optical absorption and photoluminescence (PL) spectroscopy techniques were used to characterize the optical properties of CdSe QDs. Optical properties of colloidal CdSe QDs were successfully controlled by changing the initial Cd:Se molar ratios and temperature. Optical absorption and PL spectrum both showed gradual red shift with increasing Cd:Se molar ratio and temperature. High-resolution transmission electron microscopy (HRTEM) technique were used to study the structural properties of CdSe QDs. Full width at half maximum (FWHM) values obtained from the emission spectrums were helped to prove the narrow size distribution, which coincides with the matching results of HRTEM images and theoretical calculations.

Groynes are man-made hydraulic structures constructed for a variety of purposes. They extend outside the bank in the depth of streams. Local scour usually occurs around groynes resulting in problems of interest to hydraulic engineers. In this study, laboratory experiments were conducted to evaluate the local scour around different number of groynes distributed on different spacing with different shapes. Physical models have been developed for groynes installed in a straight hydraulic channel grounded with uniform cohesionless (soil) as bed material with medium grain size (d50 = 0.69 mm). The experiments were conducted under subcritical flow and Clear- water conditions. Three different numbers of groynes (single, double and triple) were used to indicate the impact of the numbers on the local scour; such impact have been observed to be as reverse relationship, specially, for the intermediate groynes. Different spacing between groynes as (1, 1.5, and 2) times the length of groynes were used in this study. For the range tested, it has been observed that for each spacing decrease by (0.5 Lg) there was a decrease in scour depth about (20%). Also, several lengths of groynes (13, 10, and 7) cm were used, and it has been observed that scour depth is decreased about (20 - 53)% by decreasing the ratio of groyne length to main flow width (Lg/B) by (7.5%). Two different shapes of curved groynes, namely as, quadrant (quarter of a cylinder) and semi-parabolic shaped groynes were used to indicate the effect of groyne shape on the local scour. Generally, scour is decreased about (75) % in quadrant shape groynes as compared with that of semi-parabolic shape groynes.

An efficient load scheduling method to meet varying power supply needs is presented in this paper. At peak load times, the power generation system fails due to its instability. Traditionally we use load shedding process. In load shedding process disconnect the unnecessary and extra loads. The proposed method overcomes this problem by scheduling the load based on the requirement. Artificial neural networks are used for this optimal load scheduling process. For generate economic scheduling artificial neural network has been used because generation of power from each source is economically different. In this the total load required is the inputs of this network and the power generation from each source and power losses at the time of transmission are the output of the neural network. Training and programming of the artificial neural networks are done using MATLAB.

Visual cryptography is a technique of cryptography in which secret images are divided into multiple shares and are distributed to different entities. Each secret can be reconstructed by superimposing these shares using different operations. Common traditional drawbacks of all existing methods are pixel expansion and noise at output. Another major issues that can occur in existing visual cryptography systems are Cheating between share holders and Share holders cheating owner. In order to overcome these limitations, sealing algorithm is used with two applications of VC such as MIVC and EVC. Here two secret images can be send at the same time by converting them to halftone representations which in turn are partitioned as three shares in total.

Although the performance of vehicle driver has been well investigated in many types of environments, however, drowsy driving caused by vibration has received far less attention. Experiment procedures comprised of two 10-minutes simulated driving sessions in no-vibration condition and with-vibration condition. In with-vibration condition, volunteers were exposed to a Gaussian random vibration, with 1-15 Hz frequency bandwidth at 0.2 ms-2 r.m.s. for 30-minutes. A deviation in lane position and vehicle speed were recorded and analyzed. Volunteers have also rated their subjective drowsiness by giving score using Karolinska Sleepiness Scale (KSS) every 5-minutes interval. Strong evidence of driving impairment following 30-minutes exposure to vibration were found significant in all volunteers (p < 0.05).

The past decade has seen the rapid development of vibration comfort in the automotive industry. However, little attention has been paid to vibration drowsiness. Eighteen male volunteers were recruited for this experiment. Before commencing the experiment, total transmitted acceleration measured at interfaces between the seat cushion and seatback to human body was adjusted to become 0.2 ms-2 r.m.s and 0.4 ms-2 r.m.s for each volunteer. Seated volunteers were exposed to Gaussian random vibration with frequency band 1-15 Hz at two level of amplitude (low vibration amplitude and medium vibration amplitude) for 20-minutes in separate days. For the purpose of drowsiness measurement, volunteers were asked to complete 10-minutes PVT test before and after vibration exposure and rate their subjective drowsiness by giving score using Karolinska Sleepiness Scale (KSS) before vibration, every 5-minutes interval and following 20-minutes of vibration exposure. Strong evidence of drowsiness was found as there was a significant increase in reaction time and number of lapse following exposure to vibration in both conditions. However, the effect is more apparent in medium vibration amplitude. A steady increase of drowsiness level can also be observed in KSS in all volunteers. However, no significant differences were found in KSS between low vibration amplitude and medium vibration amplitude. The results of this investigation suggest that exposure to vibration has an adverse effect on human alertness level and more pronounced at higher vibration amplitude. Taken together, these findings suggest a role of vibration in promoting drowsiness, especially at higher vibration amplitude.

This study aims to investigate the potential of selected wild grasses from the Philippines as coagulant and typing sera. To do this, Euphorbia hirta L., Tridax procumbens L., and Vernonia cinerea (L) Less aqueous infusions were each subjected to blood components from healthy individuals. The plasma part of the blood was used to test for coagulation where Plasma Clotting Time (PCT) and Factor VIII screening test were the procedures used to test the different leaf extracts. On the other hand, the Packed Red Blood Cell part of the blood was used to test for hemagglutination where microscopic and macroscopic evaluations were the procedures used to test the different leaf extracts against the blood groups from the ABO system. About this study, it was found out that all the wild grasses did not give a comparable coagulation to the commercially available positive control which is Calcium Chloride while Euphorbia hirta L. gave a positive hemagglutination to Type A and Type B cells, Tridax procumbens L. gave a positive hemagglutination to Type A cell and Vernonia cinerea (L) Less gave a positive hemagglutination to Type B cells both in macroscopic and microscopic evaluations. The results show that all the wild grasses tested may not be used as a coagulant but all of them may have a potential as a typing sera.

Black mold disease caused by Aspergillus niger V. Tiegh. is the most devastating infection occurs in onions (Allium cepa L.) under field and store conditions. The use of biocontrol agents is ecofriendly approach for controlling seedborne and soilborne diseases compared to the use of toxic synthetic fungicides. This study has been designed to assess the contamination levels of onion seeds with A. niger and its effect on seed germination, and to evaluate the in vitro antifungal activity of Prunus mahaleb seeds, Commiphora myrrha resin (0.5, 1.0, 1.5, 2.0 g/100 ml), Syzygium aromaticum dry buds (clove), and Panax ginseng roots extracts (0.5, 1.0, 2.0, 2.5 g/100 ml) against black mold of onion bulbs. The fungus is seedborne pathogen which significantly contaminated onion seeds (89-100%) and reduced seed germination (39-83%). The extracts of clove caused 43-96% inhibition in spore germination followed by mahaleb (37-96%), myrrha (33-88%), and ginseng (34-87%). The highest concentration of these extracts (3.0%) did not affect seed germination, but significantly reduced seed contamination by A. niger up to 84%, 80%, 71%, and 65% for Syzygium aromaticum, Syzygium aromaticum, Panax ginseng and Prunus mahaleb, respectively. The extracts apparently inhibited the fungal growth and mold development on stored onion bulbs which indicates the antifungal property of these extracts against A. niger. Therefore, they can be recommended as effective biocontrol agents to reduce seed contamination and enhance the storability of onion bulbs. Thus, the use of healthy and certified seeds for onion production is a priority.

The Experiment was done to find out network failures and application performance relationship over distributed Wide Area Net (WAN). In order to access related application over the cloud there must be an internet connectivity which will help the respective workstations to access the remote server for applications being deployed over the network. Bandwidth improvement helps in reducing utilization over the network and it also helps in improving Application Efficiency of these Applications in terms of Response Time. Routers were configured under Enhance Interior Gateway Routing Protocol (EIGRP) to reduce utilization and to ensure load sharing over the network. Three scenarios were modeled and their performance efficiency was evaluated. A modeled computer Network with and without a fail Router under different scenarios and such Network was simulated with emphasis on the Application Performance. The Experiment was done for fifty workstations under three scenarios and these three scenarios were accessed and evaluated on experimental basis using Riverbed modeler to show the Effect of Application Network performance. The performance results show that increasing the bandwidth reduces utilization and also with the failure of one communication bandwidth, users can still access Network Application with a minimal cost.

Dissatisfaction of Project Affected People (PAPs) has been a common phenomenon worldwide and in most of the land acquisition programs carried out in Tanzania. The implementation of such programs has sometimes been delayed due to PAP’s negative attitudes as a result of dissatisfactions. This has negative consequences for communities, acquiring authorities as well as program financers themselves. This study was aimed at finding out the causes, nature and levels of PAPs’ dissatisfaction in land acquisition programs executed at Kurasini area in Dar es Salaam, Tanzania. The study explored methods used to deal with compensation complaints and evaluated the reactions of PAPs towards the said programs. Through interviews and a review of documents submitted to the ministry responsible for land acquisition regarding their dissatisfactions, it was possible to undertake the analyses. It was evident from the study that inadequate compensations, non-adherence to the laws, unfavorable resettlement practices, use of force by governments and acquiring authorities in making PAPs accept compensation, and lack of PAPs’ involvement in the acquisition processes were identified as the most critical sources of discontent. Interviews also revealed that there were some dissatisfied PAPs who did not lodge complaints for a number of reasons but were equally dissatisfied for the same reasons. The study concludes up by recommending among others, that the government and the acquiring authorities should adhere to legal procedures governing compulsory purchase and compensation, ensure that negotiations are done with all parties involved in the acquisition programs, provide alternative plots besides monetary compensation, but after all recommendations, a plan for peaceful and agreeable resettlement of the PAPs is an initiative which would reduce or eliminate their resentments.

The aim of this work is to study the hydrolysis process of cassava peel using phosphoric acid. The substrate was characterised using proximate analysis and result obtained showed that cassava peel has high hemicellulose content. The effect of process variables; acid concentration (2.5wt%, 5wt%, 7.5wt% and 10wt %) and time variation on glucose and xylose yield were studied. The maximum glucose was obtained as 2.218mg/ml at the following conditions: 7.5wt%, 1mins and 121˚C while the maximum xylose was obtained as 33mg/ml under the following conditions; 10wt%, 3mins and 121˚C. The Saeman’s model and two-fraction were used to fit the experimental data for glucose and xylose yield and two-fraction model gave the best fit for both. In conclusion cassava peel as shown by the results obtained can be used for the production of glucose and xylose.

Man needs to do some form of physical work in other to remain healthy, this work is similar to the work done by any machine or equipment and thus should be channeled to give useful output, but rather, it is usually dissipated into the environment in form of heat. The regenerative bicycle ergometer takes advantage of the greater power generated by the limbs and arms, thus conserves, converts and stores the energy dissipated by the rider with an ideal mechanical advantage of 7.6, it strategically uses simple mechanisms to magnify its work and then converts this mechanical energy into electrical energy by the use of a dynamo, with a speed ratio of 108.5 and a transmission efficiency of 89%, the rider pedals 27rpm to obtain the dynamo’s rated input of 2600rpm, giving an output of 12.6volts. The regenerative bicycle ergometer is designed and constructed to perform all the core functions of a bicycle ergometer, having an allowable load of 116.5kg and a maximum resistance of 65.33N which is equivalent to a mass of 6.66kg. The energy converted is stored in a 12volts battery, making its use flexible, clean and meeting the energy demands of man.

Natural Human Computer Interaction (HCI) is the demand of today’s technology oriented world. Detecting and tracking of face and hands are important for gesture recognition. Skin detection is a very popular and useful technique for detecting and tracking human-body parts. It has been much attention mainly because of its vast range of applications such as, face detection and tracking, naked people detection, hand detection and tracking, people retrieval in databases and Internet, etc. Many models and algorithms are being used for detection of face, hand and its gesture. Hand detection using model or classification is to build a decision rule that will discriminate between skin and non-skin pixels. Identifying skin color pixels involves finding the range of values for which most skin pixels would fall in a given color space. All external factors will be eliminated to detect the hand and its color in the image in complex background.
