Plastics have been an integral part of our life. However, disposal of these non-biodegradable (petrochemical derived) plastics poses a threat to our environment. Thus, much interest has been gained in developing biodegradable plastics. Polyhydroxybutyrates (PHBs) are polymers that accumulate as carbon/energy in microbial cells and provide an alternative to petrochemical plastic because of their biodegradability properties. However, major problems in commercializing PHB is the high production cost due to expensive carbon substrates. Therefore, the applications of cheap carbon sources have been explored. In this study, P. aeruginosa has ability to convert agro-industrial waste like Rice husk, Cotton seed husk, Walnut shell and Corn cob meal in to PHB. Highest cellular PHB content was obtained from Rice husk as source of carbon which was found to be 0.26 g/L. As Rice husk is agro-industrial waste its use in PHB production may prove beneficial, and hence may become an area of further research.
The aim of the study is to examine the impact of social media on personality development of adolescents and to identify social media factors that influence personality development. A qualitative approach has been adopted in order fully explore the subject matter without any constraints. Data was collected using only peer reviewed Journal Articles and articles from book sections. The grounded theory method was used to reach the conclusion. The findings show that use of social media is extreme in adolescents as they use not only for socializing, but also for communication, entertainment, and all the other activities. The four main social media factors that influence personality development include (i) Culture of Popularity, (ii) Unreal Standards of Appearance, (iii) Approval Seeking Behavior, and (iv) Prevalence of Depression and Anxiety. The research has two main limitations. The first limitation is that the study does not make use of primary data in forms of interviews or observation but it was made sure that only primary sources are used. Secondly, the use of qualitative approach which increases researcher bias. The findings of this study can be used to minimize the negative effects of social media on the personality development of adolescents through educational and intervention plans. The findings show that social media has an adverse effect on the personality development of adolescents. The study specifically identifies the four personality factors that are altered by the excessive use of social media. These findings can be used to develop interventions to minimize this negative impact on adolescents.
Coronary heart disease is dominant and very dangerous disease in the world. Coronary heart disease causes mortality in the world. CHD is very complicated because of many factors that affect this disease. The main factors effects on coronary heart disease are Cholesterol, Diabetes, Depression, and Hypertension. I believe four factors above have tremendous and direct effects on this disease. The rate of death is different according to country, age, and gender. The lack of physical activity is the same in men and women so the rate of hypertension, diabetes, and obesity more common. The main and dangerous point in coronary heart disease occurs when the coronary artery get atherosclerosis. As a result, the fat particles constrict the coronary artery so the blood, oxygen, and sufficient material don't flow to the heart completely. The main purpose of this model is to minimize the risk factors of coronary heart disease. As a result, I believe we can minimize and control this disease by doing more exercise, getting enough sleep, staying away from smoking and drinking, eating low animal products, and more eating fruit and vegetables. This paper goals to review the coronary heart disease and inquire its connections among different factors that must be taken into consideration throughout the process and how to prevent ourselves from risk factors.
The present study investigates the anti-nutrient composition of Ocimum gratissimum, Corchorus olitorius, Murraya koenigii Spreng and Cucurbita maxima following standard methods. Anti-nutritional factors are chemical substances which act to reduce nutrient intake, digestion, absorption and utilization of nutrients which may accumulate in the body to toxic level if the diet is not varied. The qualitative analysis revealed the presence of flavonoids, cardiac glycosides, alkaloids, tannins and phenols in the plant leaves using methanol, ethanol, and petroleum ether as extraction solvents except for saponins in which water was used as the extraction solvent. The differences in mean values were statistically significant at p < 0.05. The highest level of anti-nutrients were found in the following order: flavonoids (7.20 ± 0.15 %) in Cucurbita maxima; cardiac glycosides (13.01±0.03 %) in Ocimum gratissimum; alkaloids (8.82 ± 0.08 %) in Ocimum gratissimum; phytates (0.06 ± 0.00 %) in Corchorus olitorius; haemaglutinins (1.06 ± 0.00 mg/l) in Cucurbita maxima; saponins (9.26 ± 0.20 %) in Cucurbita maxima; tannins (1.45 ± 0.03 %) in Corchorus olitorius; oxalates (1.07 ± 0.07 %) in Murraya koenigii; and phenols (0.68 ± 0.02 mg/l) in Corchorus olitorius. However, the level of anti-nutrients in these plant leaves falls within safe level but should be consumed with care to prevent over-accumulation.

There is a positive correlative relation of statistical significance at (0.01) level among life problems based- anxiety, health & death anxiety, future anxiety from one hand and emotional adjustment (from the other hand). 2. There is a passive correlative relation of statistical significance at (0.01) level among mental anxiety, anxiety of failure in future, future anxiety and goal attainment duty. 3. There are not any differences of statistical significance at (0.05) level in view of results of Future anxiety scale & Adjustment Of University scale and according to SPECIALIZATION FIELD and GRADE variant (Future despair dimension was excluded from future anxiety score). The researcher recommended to establish Psychology Counseling center in universities to render counseling services for the benefit of students in a way that enable them to adjust with university and protecting them from psychological disorders.
Consumers demand for quality of food has triggered the need for the development of a number of non-thermal approaches to food processing, of which high-pressure technology has proven to be very valuable. This review aims to identify the opportunities and challenges associated with this technology. In addition to discussing the effects of high pressure on food components, this review covers the combined effects of high pressure processing with: gamma irradiation, alternating current, ultrasound, and carbon dioxide or anti-microbial treatment. Further, the applications of this technology in various sectors— fruits and vegetables, dairy, and meat processing—have been dealt with extensively. The integration of high-pressure with other matured processing operations such as blanching, dehydration, osmotic dehydration, rehydration, frying, freezing / thawing and solid-liquid extraction has been shown to open up new processing options. The key challenges identified include: heat transfer problems and resulting non-uniformity in processing, obtaining reliable and reproducible data for process validation, lack of detailed knowledge about the interaction between high pressure, and a number of food constituents, packaging and statutory issues. The aim of this review is the different aspects and potential application of HPT and critically examines HPT related studies. Different types of food product (fruits and vegetables product, Dairy product, Meat product, Starch product etc.) are preserved and maintained the nutritional qualities for longer time.

This paper focuses on discussing and demonstrating multiculturalism. It also discusses the important factors that affect multiculturalism and how multiculturalism might be incorporated into the society to create a more convenient environment for all people. This search was carried out using peer reviewed journal articles and books which provided us with sufficient information on the subject of multiculturalism. Other readings which gave more insight into this work were done through the JSTOR and IEEE websites. There are four main factors which affect Multiculturalism. These factors stress the main importance of multiculturalism and the interaction between cultures. For instance, communication between cultures is done through language. In addition, business can also have an impact on the interaction between two or more cultures. Furthermore, it has been highlighted that education plays a vital role with regards to the issue of multiculturalism. Multicultural education may affect the new generation. Children are known to adapt more easily to multicultural situations. Moreover, the interaction between cultures could be affected by the cooperation among nations. The limitation and the statistic are that it is not easy to get the specific results from these factors. For instance, in the world wide the globalization is considered as a way to face the change in multiculturalism. With this limitation we could obviously see the fundamental of multiculturalism. Finally, the evidence supported the attitude multiculturalism's ability that is based on the perspective these factors.

Kenya is facing an increasing growth of informal settlements in her urban centers. As rapid urbanization takes its toll, so has the development and growth of informal settlements. The social, economic and environmental challenges which informal urban settlements face today, coupled with the speed of urban expansion, require an urban planning approach that integrates the concept of land information management systems in informal settlements in its blueprint. Based on a study in the capital city, Nairobi, this paper describes the characteristics of settlements and land ownership in of informal settlements in Kenya. First, a survey was conducted using a questionnaire to get an insight into the current situation of the informal land development sector in the study area. Structured interviews were used at the settlement level to gain knowledge on the operations of land management. Finally, focus group discussions were conducted with the village elders and headmen at the settlements to gain more insights on land ownership systems. Data for the study was analyzed descriptively. The study established that land information management interventions in these informal settlements are uncoordinated, ad hoc and overlapping. There is also lack of systematic dissemination of land information and updated land information since the stakeholders' interventions in land information management are uncoordinated and therefore undermine efficiency of environmental planning. Besides, there is poor security of land information due to lack of back-up data in these settlements and information on land registration, registration of rights and rights holders is in itself insufficient and does not address environmental planning. There is therefore need for the government and other agencies to create a platform for discussion, monitoring and coordination of the various land data collected to ensure interventions for environmental planning are coordinated and not overlapping.
