Jatropha seed oil was employed in the preparation of different alkyd resin samples using alcoholysis and polycondensation process. The alkyds formation was monitored by determining the acid number of the reaction mixture at time intervals and the extents of the polyesterification reactions were evaluated. Both the Jatropha seed oil and its alkyd resins were characterized by Fourier Transform Infra red (FTIR) spectroscopy. Performance evaluation shows that properties of alkyd resin derived from Malic anhydride are comparable with pthalic anhydride alkyd resins.

Ethyl acetate extract of the Stem bark of Piliostigma reticulatum was tested against clinical bacterial strains including; Escherichia coli, Klebsiella aerogenes, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Streptococcus pyogenes, Staphylococcus aureus, Serratia marscences, Shigella dysenterie and Yersinia enterocolitica using the agar well diffusion method of Perez, (1990). Purified extract were subjected to spectra analysis using NMR and GCMS.Result obtained revealed that the plant extract has antibacterial properties against E. coli, Str. Pyogenes, K.

Study Design: Translation and validity and reliability testing. Objective: To adapt the low back pain rating scale (LBPRS) cross-culturally to Arabic language, investigate the validity, reliability and feasibility of the Arabic version of LBPRS in an Arabic-speaking sample with low back pain. Method: The English version of the LBPRS which had 3 components (back and leg pain, disability index and physical impairement) was translated into Arabic (LBPRS-Ar) and back-translated according to established guidelines.

Background: The study was conducted in Gagnoa, in central-western Côte d'Ivoire in one of the main areas of rainfed rice production. Objective: The objective of this study was to assess the natural physical fertility status of the soils used for rainfed rice in the Gagnoa area. Methods: The test was carried out on the top of a slope at the research station of the National Center for Agronomic Research (CNRA) of Gagnoa.

Population resettlement is a complex socio-economic process that reflects many aspects of society, and is the most important spatial form of interaction between society and nature. From these positions, the article considers various aspects of the territorial distribution of the population and the formation of a modern ethnic map in the Kabardino-Balkarian Republic (KBR) in connection with its administrative and territorial structure. The most important components of the population settlement process are three groups of factors: socio-economic, environmental (natural) and demographic.

A study was conducted among 315 randomly selected pigeon farmers across different locations in Gamawa L.G.A to investigate their traditional breeding methods, breeding objectives and traits preferences for selecting breeding stocks. The result obtained showed that majority (75.485%) of the farmers kept the local pigeon breeds over the cross breds (20.70%) and exotic breeds (3.82%). Most of the farmers (42.99%) sourced their breeding stocks from within their flocks over other sources. Most (35.67%) of the farmers kept pigeon for hobby and for meat (32.48%) followed by other reasons.

Results of this research showed that all factors, i.e. buying decision, artist, television advertising media, price, and product quality gave significant effects on brand awareness. Meanwhile, total effect of variables artist, television advertisement media, price product quality on buying decision through brand awareness gives significant effect. Research method is illustrated by path analysis to easily observe the impacts that are being studied. The cause and effect path was established from variables being used.

An experiment was conducted in the nursery of Regional Agricultural Research Station, Akbarpur, Moulvibazar; where IBA, NAA, and IAA were used for rooting of black pepper (BARI Black Pepper1: Jainta Gulmorich) on three growing media (soil:cowdung: coco dust, loamy soil, and wet sand). From this experiment, it is evident that growing media has less effect on proliferation of black pepper cuttings where Indole-3-butyric acid (IBA) and Indole-3-acetic acid (IAA) was found effective for providing conditions for rooting as well as survivability in the long run.

The study examines a linguistic phenomenon of near synonyms investigated by one of the features in a corpus tool of Sketch Engine namely Word Sketch Difference. The feature functions to compare and contrast two words through collocation analysis by presenting their collocates categorized on the basis of grammatical relation. Using the data derived from the English Web Corpus 2013 (enTenTen13), the present research aims to explore near synonyms by observing the usage of the English adjectives Brave: Courageous by employing the analyses of collocation.

Background: Patellofemoral pain (PFP) has a debilitating effect on sufferers, daily lives by reducing their ability to perform sporting and work related activities pain free. The Kujala Patellofemoral Disorder Score (KPS) was particularly designed and developed for the assessment of patients having anterior knee pain as well as patellofemoral conditions.
