The aim of this paper is to determine the effect of salinity on the growth of some previously known petroleum biodegrading Bacillus sp. under laboratory condition where petroleum hydrocarbons are the sole source of carbon.Bushnell-Hass (BH)mineral salt media consisting of different NaCl concentrations (0.0 to 0.4 mole/liter or ML^-1) were prepared and supplemented with 2% kerosene/diesel/engine. The media were then inoculated with the bacteria namely Bacillus pasteurii, B. badius, B. cirroflagellosus, B. circulans and B. brevisindividually. After 7 days of incubation, bacterial growth was determined by measuring the optical density (OD) of the media at 620 nm. We found that salinity has a great impact on the growth of the bacteria under investigation. A NaCl concentration ranging from 0.05 to 0.3 ML^-1was found to have a positive impact on the growth all 5 Bacillus sp.NaCl concentrations below and above the said range were found to be growth limiting.Interestingly our findings indicate that the maximum growth of a bacterium depends not only on the optimum salinity level but also on the type of petroleum hydrocarbons provided.The findings of this study are important for understanding the impact of salinity on the biodegradation process of petroleum hydrocarbons and to develop optimized application approaches to sweep such pollutants from contaminated sites.

One of the progress important channels in organization productivity improving is. Human resource productivity, the driving force of progress and development organization. This study is to explain some of the ways to improve productivity, the institutional methodology is used, and emphasized that the path to improved productivity, the institutional reform passes. Institutionalism view that, based on the belief that these institutions are, the worldview of people to determine, therefore, ideals and goals of each individual, strongly influenced by institutions that influences the direct and their indirect , has grown. The study acknowledges that a number of factors, the productivity of human resources effective, the main efficient institutions, to improve productivity, the reform of the institutions are: The educational institution: as a way to solve nodes work, the reward: to motivate to do useful work, and the generator and regulations: as an official body may, construction and improvement work in other institutions, to formally recognize forgive documented.

In the present study we have evaluated effect of different plant diets on the amount of food consumption, absorbed, converted and metabolized in the fresh water fish Cyprinus carpio. We discussed the feeding rate, absorption rate, conversion rate and metabolic rate of fished when they consumed different foods, and the absorption and conversion efficiency were observed. The maximum absorption efficiency was observed in the potato fed fish and the minimum was observed in the radish fed fish. But maximum conversion efficiency was noticed in cabbage.

Culture is a complex issue that essentially includes all of a group’s shared values, attitudes, beliefs, assumptions, artifacts, and behaviors. Culture is broad — encompassing all aspects of its internal and external relationships—and culture is deep in that it guides individual actions even to the extent that members are not even aware they are influenced by it. Scholars tend to agree that the root of any organization’s culture is grounded in a rich set of assumptions about the nature of the world and human relationships. This study sought to establish the effect of organizational culture in the performance of the County Government of Taita Taveta. The research design which was employed is a descriptive one involving a cross sectional survey. The target population was 1,513 staff of the County Government. The sampling technique to be used will be stratified random sampling. Also, Primary data collection will be used and the data collection instrument to be utilized will be a structured questionnaire. The sample size will be 384 employees across the cadres of the County Government. The data will be interpreted, analyzed using standard deviation and the linear regression analysis model and then presented using tables, charts and graphs.

The study was guided by the following specific objectives: the effects of customer focus, top management commitment, people management and process management on the performance of construction projects. The descriptive research design was used in the study. The study was carried out in Kiambu County. Questionnaires were used as the tools of data collection. Questionnaires were used to collect data from the employees of the construction firms. Quantitative data was analyzed using descriptive statistics which entailed use of frequencies and percentages. Inferential statistics where the researcher employed Chi-square and The Spearman Rank Order tests were used. The study found out that; most of the respondents were of the view that their organizations placed a major emphasis on communication and training processes with a view of enhancing customer focus. The top management was fairly evaluated on quality performance. The capacity of their project teams in terms of periodic training needs assessment to ensure sustainable construction projects performance. The organizations had put in place fair mechanisms to ensure that the team members fully comprehended the business processes within the organizations. The study recommended that: the construction companies should seek to place greater emphasis on customer focus. This is by way of always aligning their quality management practices and ethos on the clients’ needs with a view of seeking to ensure maximum satisfaction and repeat buying. The top management in the construction industry should seek to always lead by example and from the front in seeking to enforce quality standards.

The Interacting Boson Model is applied to the even isotopes . Excitation energies, electromagnetic transition strengths, quadrupole and magnetic dipole moments, and ?(E2/M1) multipole mixing ratios, monopole transitions and mixed symmetry states have been described systematically. It is seen that the properties of low-lying levels in these isotopes, for which the comparison between experiment and IBM-2 calculations is possible, can be satisfactorily characterized by the Interacting Boson Model-2.

Oral health care as a part of primary health care system, is incorporated in health system in 1995. Based on this program, pregnant women and children of 0-12 years old are considered as target groups. The purpose of this study is the evaluation of benefit rate among target groups from governmental oral health care services in 2010 and the comparison of those services with that of 2011 namely, one year after the beginning of health sector reform in Southern Provinces of Iran. In this cross-sectional study, 268 urban and rural health care centers in southern provinces have been evaluated based on related statistical sheets in 2010 and 2011. Data entered in data sheet and analyzed by excel software. The effect of health sector reform in dental health care section in southern provinces has been successful so that this program has shown positive beneficial rate in dental services such as restorations and fissure sealant therapy in 2011 with respect to 2010. Improvements of oral health care programs such as better delivery of dental services and increase in awareness of target group in southern provinces, has caused an increase in benefit rate from dental services among them. The data obtained in this study, showed an increase in this rate in 2011 in comparison to 2010.

The failures of the bituminous pavements are not only due to increase in traffic but also due to extreme climatic conditions prevailing in the country. The addition of polymers to bitumen can improve the quality of binders and enhance the properties of binders used in the road construction. Bitumen ageing is one of the principal factors causing the deterioration of asphalt pavements due to the prolonged exposure to air and environmental conditions. Short-term ageing occurs when binder is mixed with aggregates in a mixing facility. Long-term ageing occurs after pavement construction and is generally due to environmental exposure and loading. The properties of bitumen mainly depend on the age of bitumen. Therefore there is a need to study the properties of modified bitumen before and after ageing. In this paper the effect of Aging on the physical properties of SBS (Styrene Butadiene Styrene) modified bitumen is discussed.

Sourdough fermentation is one of the oldest biotechnological methods of food preparation. Macaroni, as one of the world's most widely consumed cereal products, used in large quantities, because of its nutritional value, significant amounts of complex carbohydrates, protein, vitamin B & iron. In this study, We evaluated physicochemical properties of fermi macaroni after adding spray dried lactic acid sourdough (12, 8, 5% w/w) of three species of Lactobacillus acidophilus, Lactobacillus cazei & Lactobacillus plantarum in 10 treatments of semolina with 88, 92, 95 & 100 grams. As a result, according to the obtained data, the sample containing 8% Lactobacillus acidophilus was chosen as the sample with superior physicochemical properties.

To solve the problem of microbial outbreak which is a major challenge to human health in developing countries like Nigeria, herbal drugs are being looked as an imperative source for discovery of new agents for treating various ailments related to microbial infections. In this present study, the seeds of Piper guineensii and Buchhloziacoriacea were evaluated for their phytochemical constituents and antimicrobial properties.
