Agronomy Journal of Nepal , 2011, DOI: 10.3126/ajn.v2i0.7524
Abstract: Gray leaf spot (GLS) is an important and destructive disease of maize in the hills of Nepal. The occurrence of this disease is recorded for the first time in the country in 2006. Several genotypes of maize supposed to be resistant to gray leaf spot in SARMP Zimbabwe and CIAT Colombia were evaluated together with other varieties in observation nursery conducted at farmer’s fields as well as at Khumaltar (NARC research station in the Kathmandu Valley) during 2008 and 2009. Ten out of 28 genotypes of maize were identified as resistant to moderately resistant to GLS. The disease incidence was higher on the open pollinated varieties of maize. The severity of GLS on genotypes of maize observed as 3.0 and 2.2, respectively at Baluwapati and Dhungkharka in Kavrepalanchwok and 2.0 at Khumaltar in Lalitpur during 2008. The severity of GLS was observed as high as 2.4 at Pakhribas in Dhankuta and 1.7 at Khumaltar in 2009.

Investigation of Surface Tryptophan of Protein by Selective Excitation at 305 nm  [PDF]
Vishvanath Tiwari, Monalisa Tiwari
Journal of Biophysical Chemistry (JBPC) , 2015, DOI: 10.4236/jbpc.2015.63009
Abstract: Intrinsic fluorescence of tryptophan is a powerful tool that is used to investigate structure, dynamics, and folding-unfolding of proteins. Here, we have signified the importance of selective monitoring of “surface” tryptophans from the “buried” tryptophans in a protein via selective excitation of surface tryptophan using light of 305 nm wavelength. We have also enlightened the effect of pH and temperature on the conformation of protein by selective excitation of surface tryptophan of protein using 305 nm light. The result concludes that this novel approach could be used to investigate surface tryptophan of protein selectively at diverse conditions.
Gender Dimensions of the Experience of the Burden of Epilepsy: An Example of the Manguissa Community in Cameroon
TP Ntaimah
African Anthropologist , 2008,
Abstract: This article examines the effects of gender in the experience of the burden of epilepsy in the Manguissa culture. This exploratory research combined a range of qualitative and quantitative techniques to meet the objectives. In-depth interviews and photo voice1 were used to collect qualitative data, while quantitative data collection relied on SF12 Scale, ComQol and semi-structured questionnaire. Study findings highlight gender as affecting the level to which one feels the burden of epilepsy. The dichotomy between the sexes was seen in the relationship with family members and the community; intimacy or relationship with the opposite sex; perception of importance and satisfaction about life; and control over life and emotions. This study suggests that being female and having epilepsy in the Manguissa culture is better than being male and having the same condition. This is because females enjoy intimacy and are capable of procreating, so they are perceived as those who still have things to offer despite their condition. Although females are emotionally diminished as compared to males, they are more optimistic about the future than males. We recommend equitable attention and resource allocation at the family level as the first solution to the burden felt by people with epilepsy.
Economic Evaluation of Crop Farms Acquired for Crude Oil Production Activities in Rivers State of Nigeria

African Research Review , 2011,
Abstract: This study focused on the economic evaluation of crop farms acquired for crude oil production activities in Rivers State, Nigeria. The objectives include estimating the areas of crop farms acquired and economic evaluation of crops lost due to the various crude oil production activities in the state. A multistage sampling technique was used to collect data from 169 crop farmers whose farmland were affected with different crude oil exploration activities via questionnaires. The results showed that a total of 682.91ha of crop farms were acquired for crude oil exploration purposes out of which pipelines laying (25.21%), flow stations (21.51%) and oil well sites (20.34%) topped the list. The results further showed that the total value of economic loss due to crude oil production activities was $165,287.10 out of which pipelines laying accounted for $43,741.25, flow stations ($36,387.92), oil well sites ($31,334.67), gas flaring sites ($10,485.63). The study showed that large areas of crop farms in the state were acquired for crude oil production activities. Due to the small scale nature of farms in Nigeria, a lot of crop farmers in Rivers State were negatively affected which had resulted into agitation for resource control, continuous violence, conflicts, protests and impoverishment.

Abstract: Adipositas ist ein weltweit zunehmendes Gesundheitsproblem. Sie ist ein wichtiger Risikofaktor für die Entstehung der arteriellen Hypertonie. Die Diagnostik der Hypertonie beim übergewichtigen Patienten ist problematisch. Die wichtigsten nicht pharmakologischen Ma nahmen sind Gewichtsreduktion und k rperliches Training. Da nur wenige der Patienten diese Ziele erreichen, sind medikament se Ans tze notwendig. Hierbei mu auf die Begleiterkrankungen, auf die Vertr glichkeit und die Compliance des Patienten geachtet werden.

Advances in Chemical Engineering and Science (ACES) , 2012, DOI: 10.4236/aces.2012.21005
Abstract: This review article is written on the investigations of nanomechanical properties of coatings by using nanoindentation techniques. The focus is on the studies that were conducted on epoxy polymer, silicones and their hybrid materials. The article describes a large number of developmental studies that are conducted on coatings. Materials properties such as nanoindentation hardness, modulus, scratch, wear and viscoelastic behavior have been described. Moreover, the article summarizes various studies that mention the use of different nanoparticles in coating formulations that could improve the mechanical strength and service life span of the coatings. The mode and mechanism of material’s failure has been outlined and discussed.
Regulatory T Cells and Parasites

Journal of Biomedicine and Biotechnology , 2011, DOI: 10.1155/2011/520940
Abstract: Human host encounters a wide array of parasites; however, the crucial aspect is the failure of the host immune system to clear these parasites despite antigen recognition. In the recent past, a new immunological concept has emerged, which provides a framework to better understand several aspects of host susceptibility to parasitic infection. It is widely believed that parasites are able to modulate the magnitude of effector responses by inducing regulatory T cell (Tregs) population and several studies have investigated whether this cell population plays a role in balancing protective immunity and pathogenesis during parasite infection. This review discusses the several mechanism of Treg-mediated immunosuppression in the human host and focuses on the functional role of Tregs and regulatory gene polymorphisms in infectious diseases.
The job satisfaction of principals of previously disadvantaged schools: new light on an old issue
TP Maforah, S Schulze
South African Journal of Education , 2012,
Abstract: The aim of this study was to identify influences on the job satisfaction of previously disadvantaged school principals in North-West Province. Evans’s theory of job satisfaction, morale and motivation was useful as a conceptual framework. A mixedmethods explanatory research design was important in discovering issues with which these principals struggled. Thirty principals of secondary schools located in the rural villages and townships in the province were purposefully selected. A structured questionnaire was used during the quantitative phase. The items in the questionnaire determined the principals’ views on intrinsic and contextual factors related to their working environment. These items were followed by open-ended questions. Additional qualitative data were obtained through interviews with eight principals selected from the same group. Although the principals enjoyed intrinsic aspects of their work and positive interpersonal relations at their schools, the results were significant in determining how the principals struggled with other issues (e.g. policies and practices of the Department of Basic Education). Underpinning factors were unrealistic expectations and negative perceptions that influenced their professionalism. A key factor that emerged was power versus powerlessness.

Crush Syndrome Case Report and Literature Review
Dinesh Dhar,TP Varghese
Macedonian Journal of Medical Sciences , 2010,
Abstract: Extensive muscle crush injury culminating in a crush syndrome or traumatic rhabdomyolysis is often lethal unless treated actively on war footing. The causes of death in crush syndrome include hypovolemic shock, hyperkalemia, hypocalcemia, metabolic acidosis, acute myoglobinuric renal failure and the acute muscle – crush compartment syndrome. The literature is divided on the treatment, while some surgeons advocate early surgery others maintain, late surgery is best. We report a case of young man with crush syndrome presenting 10 hours after he was entrapped under his car following road traffic accident. An attempt has been made to review the literature on this topic.
