This paper is going to deal with the topic of trust within real existing leadership relations. The design tries to test trust and trustworthiness in ongoing relations of leaders and followers in existing companies in order to gain more validity of data than other designs, often using students as probants. The paper first discusses traditional ways of measuring trust – mostly done by questionnaires and illuminates their weaknesses. Then a different way is going to be described by adopting and adapting the trust game to make it applicable in companies. The design focusses on real decisions regarding trusting and trustworthy behavior by putting the participants into situations where they have to transfer virtual money. Additional questions about the demographic background of the participants are formulated. Also a guideline for the implementation of the experiment in companies has been formulated.

Information, now a day, is considered equally valuable as monetary resources. Extension communication media disseminate precious information that can change the life of many rural poor farmers. This study was progressed with the purpose determining shrimp farmers usage and preference of extension communication media (ECM) in some selected villages of Bangladesh. This study was conducted in a selected union of Bagerhat Sadar Upazila in Bangladesh. Data were collected in the first quarter of June, 2015. This research was predominantly based on primary data. However, secondary sources were also consulted to reveal the present status farming, production and marketing of shrimp in Bangladesh. Data were collected using structured interview schedule from 72 purposively selected shrimp farmers. Usage of ECM was determined based on weighted mean; whereas preference of media was determined considering the frequency and percentage. The association between predictor and criterion viable was measured employing chi-square analysis. Descriptive statistics such as mean, standard deviation, median, range, etc. were also used to describe the characteristics of respondents. The findings of the study represent that 72.2% of the farmers had moderate to low usage of extension communication sources. According to the choice of the respondents, the most preferred extension communication media were television followed by government and NGO extension agent. Chi-square analysis revealed that among eight selected variables education level, economic status, and availability of extension communication sources had a positive relationship with the usage of extension communication media. This study further revealed that farmers had different types of information need, of which the important aspects were disease management, scientific culture procedure of shrimp, salinity management, credit sources, and market related information. Despite monumental prospects of earning foreign currency, shrimp sector in Bangladesh is still suffering from a number of impediments like chronic viral diseases, increasing salinity, lack of adoption of scientific practices, absence of secured market facilities, availability of credits, etc. Farmer’s usage of ECM appears satisfactory. However, their usages did not cohere their preference. Lamentably, their usage of rich and trustworthy ECM is still very limited.

This is a very short research work representing an homage to the regretted Professor George Isac, Department of Mathematics and Computer Science, Royal Military College of Canada, P.O. 17000, Kingston, Ontario, Canada, K7K 7B4. Professor Isac introduced the notion of “nuclear cone” in 1981, published in 1983 and called later as “supernormal cone” since it appears stronger than the usual concept of “normal cone”. For the first time, we named these convex cones as “Isac’s Cones” in 2009 , after the acceptance on professor Isac’s part. This study is devoted to Isac’s cones, including significant examples, comments and several pertinent references, with the remark that this notion has its real place in Hausdorff locally convex spaces not in the normed linear spaces, having strong implications and applications in the efficiency and optimization. Isac’s cones represent the largest class of convex cones discovered till now in separated locally convex spaces ensuring the existence and important properties for the efficient points under completeness instead of compactness.

Solar dryer was developed and comparison between using solar energy and air-sun drying methods with sliced plantain and maize (shelled corn) were assessed. The dryer consist of a solar collector panel (concentrator type), a thermal storage unit and a drying chamber. The solar chamber was tilted at 7° to the horizontal with the aid of four supports at two differ heights and was covered with the transparent Polyvinylchloride (PVC) film, of 0.15 mm, thickness. The absorber material used was aluminium pipe 145 cm long of external diameter 5 cm, painted black and fixed at the focal point of the parabolic mirror. The thermal storage unit and the drying chamber were built of wood because of its good insulation properties. Results showed the collector outlet, storage unit and drying chamber temperatures ranged from 37°C–47°C, 36°C–46°C, and 33°C–45°C, respectively.  About 70.1% of moisture evaporated using solar dryer for plantain as compared to 45% using open air drying. Also more moisture evaporated from the maize (100%) using solar dyer than using open air drying (65%). The degree of variation between using solar dryer and open air drying was found to be statistically significant (P = 0.05) for both treatments. Results showed that using solar collector/dryer evaporated more moisture from the products than using the open –air sun drying.

The Numerical Study of Efforts from the 4r Symmetrical Spherical Quadrilateral Mechanism

Ion Bulac

Current Journal of Applied Science and Technology, Page 1-12
DOI: 10.9734/BJAST/2016/24822

The 4r spherical quadrilateral mechanism is made of three mobile elements and one fixed (the basis) connected through the four revolute kinematic pairs, whose axes intersect at the same point. It is multiple statically indeterminate and for calculating the efforts from kinematic pairs it is using the elastic linear calculation, in which the mechanism elements are considered deformabile rigid. The displacements in the local systems of reference, produced by external requests are small and defined by the vectors of small rotations, which act similarly to the angular velocity and small displacements, defined by displacement vectors. The use of the relative displacements method, with the expression of displacements under the form of a column matrix in plukeriane coordinates, makes possible the calculation of efforts and reactions in the kinematic pairs of this mechanism. The results of the numerical solving of this problem will be presented under the form of a diagrams and will be commented.

Aims: Investigations were carried out to determine the mycoflora and moisture content of garri sold in Anyigba, Kogi State.

Methodology: Samples of white and yellow garri collected from two major open markets namely; Garage and Anyigba old markets were used for the study. Enumeration of fungal counts in all samples was carried out using the pour plate method. Isolates were identified based on examinations of conider heads, phialides, conidiophores, and the presence or absence of rhizoids and data analyzed using SPSS version 18.0. The moisture content of each sample was also determined.

Results: Moulds isolated from these samples were; Aspergillus spp, Rhizopus spp, Penicillium spp, Mucor spp and Neurospora spp. Higher mould species were recorded in yellow garri samples compared with that in white garri samples. The mean total fungal counts showed that white garri ranged from 2.03 x 104 to 6.40 x 106 while yellow garri was from 3.96 x 104 to 8.60 x 106. Significant differences in mean fungal counts were recorded in the various dilutions of white and yellow garri (P = 0.05). Results from this study revealed high moisture contents which were not within safe levels and encouraged the growth of fungi.

Conclusion: Proper handling, packaging and storage under hygienic conditions are recommended. Also proper drying of garri to lower its moisture content should be encouraged.

Zygophyllum coccineum L. (Family Zygophyllaceae) was collected from two habitats namely Wadi Hagul and Nile Delta coast. Plant leaves from both habitats contained appreciable content of total phenols and total flavonoids. The contents of these compounds were remarkably higher in desert than coastal habitat. Alkaloids, saponins and tannins are detected in plant leaves from both habitats, however their contents varied. Tannins and alkaloids are found in desert habitat with higher content compared to the coastal one, however the content of saponins was higher in coastal than in desert plants. The leaves of Z. coccineum contained glucosinolates which was higher in desert than in coastal plants. Proline and total ascorbate were lower in coastal than the desert plants whereas total glutathione was higher in coastal than desert area. It was noticed that the soluble protein as well as the soluble carbohydrate were lower than their insoluble counterparts in the leaves. Amino acids analysis revealed that cysteine and methionine were the dominant amino acids in leaves of plants from the two habitats. Alanine content was higher in coastal than desert plants. The total chlorophyll was higher in desert plants than in coastal plants. Z. coccineum leaves from both habitats showed remarkable activities of pyruvate kinase, pyruvate dehydrogenase, glutamine synthetase and phosphogluconate dehydrogenase. The desert plant is the best source for the plant material for medical use.

DOI: 10.9734/BJAST/2016/24815

Fish is one of major sources of dietary protein in Nigeria, as such; private and public fish ponds abound across the country. Fish pond owners across the country face multiple problems such as seepage, ponds overtopped, subsidence, dike crack, reduction and settlement and piping which often results in decline in fish production and loss of investment. Therefore, the problems confronting the farmers must be addressed. To mitigate the problems, pond must be properly designed and constructed. This study assessed the basic and technical parameters needed for adequate pond design and construction. Types of fish pond and its components were included hearting and core; cut-offs; upstream clay blanket; filter blanket; seepage drains; berms and loading berm; upstream and downstream slope protections; and relief well were highlighted. The topography, water source, soils, vegetation and climatology and its important and effects on pond design and construction were examined. This study also examines the parameters needed for safe design and construction. One must keep in mind that the ideal site is not always available. A universal pond design may not be adequate in many situations; therefore, one design is not practically feasible. Deficiencies of the site are often mitigated by making a series of choice of components. Before installing a pond, it is important to remember that no pond will be maintenance free. However, upkeep can be minimized with good design and construction.
