Himalayan Journal of Sociology and Anthropology , 2008, DOI: 10.3126/hjsa.v3i0.1494
Abstract: Normal 0 false false false MicrosoftInternetExplorer4 Pokhara valley is located in western Nepal at an elevation of about 3,000 feet above sea level. It was declared a municipality in 1959 with an estimated population of 4,000. Since then, the city of Pokhara has faced tremendous growth pressure. Its population reached 200,000 in 2005 - a 50-fold increase in population in 46 years. Land prices have increased at a much higher rate than the population. Most of the arable land has been replaced by roads and buildings. There is a concern that Pokhara is facing growth pressure similar to that of Kathmandu Valley, as described by Pradhan and Perera (2005). As land prices soar, there is tremendous pressure on public land for development, and the municipality has not been able to maintain open space for public use. Pokhara has established few sites as public parks, and most of these parks are small parcels of land fenced for protection from cattle and water buffalo with few or no plants/ flowers and other resources for leisure time activities. There are no plans for the development of a nature park or a green space area where people could see, feel and touch ornamental plants and flowers. Furthermore, the city lacks an open green space where people could walk, jog or spend leisure or free time. ?

Floristic Diversity and Important Value Indices of Tree Species in Lower Kanchenjunga Singhalila Ridge Eastern Nepal  [PDF]
Nar Bahadur Khatri Chhetri, Krishna Kumar Shrestha
American Journal of Plant Sciences (AJPS) , 2019, DOI: 10.4236/ajps.2019.101019
Abstract: The present paper is based on the finding of floristic diversity inventory research work conducted in Lower Kanchenjungha Singhalila Ridge, in Nepal side of Eastern Himalaya. Knowledge on floristic diversity of an area can reflect the total resources, their use patterns and conservation status which have a key role for making conservation strategies and policies. Analysis of vegetation helps to develop detailed picture of plant communities of that region. A total of 299 plant species belonging to 184 genera and 86 families were found in the Lower Kanchenjungha Singhalila Ridge. Dicotyledonous flora includes 69 families, 150 genera and 229 species whereas Monocotyledonous flora includes 15 families, 32 genera and 39 species. On the basis of floristic analysis Rosaceae was found to be the largest family with 23 species followed by Ericaceae 17, and Lauraceae 9 species. Current study furnishes three new addition to the flora of Nepal viz. Begonia flaviflora H. Hara (Begoniaceae), Carex cruciate Wahlenberg var. argocarpa C. B. Clarke (Cyperaceae), and Strobilanthes helicta Anderson (Acanthaceae). Of this total, 30 woody tree species with 551 individuals and 23 genera were recorded from the altitudinal range of 2100 - 3000 m of study area. The highest relative frequency was recorded by Lithocarpus

Abstract: Cyananthus Wallich ex Bentham, the only genus of Campanulaceae with superior ovary, is revised to clarify infrageneric relationships and phylogeny of the genus. Evidence obtained from the comparative gross morphology, anatomy, palynology, and karyomorphology recommends a new infrageneric classification of the genus, recognizing 23 species, belonging to two subgenera, four sections and four subsections. One subgenus(Subgen. Micranthus), one section(Sect. Suffruticulosi) and two subsections(Subsect. Flavi and Subsect. Lichiangenses)are described as new taxa. New combinations at sectional(Sect. Annui) and subsectional(Subsect. Stenolobi) ranks are also proposed. The genus Cyananthus is strictly distributed in the high mountains of China(Xizang, Yunnan and Sichuan), extending to Bhutan, Nepal and India(Kumaon-Garhwal, Assam and Sikkim), with altitudinal ranges from 2500~5300 m. It is observed that 13 species are endemic to SW China and only three species are endemic to the Himalayas(two species in Nepal and one to NW India). It is evident that Cyananthus is one of the most primitive genera of Campanulaceae and within the genus, subgenus Cyananthus(Sect. Stenolobi) is more primitive than the subgenus Micranthus. It is also suggested that SW China(most probably Yunnan) is the center of origin of Cyananthus, considering the occurrence of as many as 20 species of Cyananthus, representing several primitive taxa and many endemic species.
Public Perception of the Quality of Academic Education Program
Binod Krishna Shrestha
Journal of Education and Research , 2013, DOI: 10.3126/jer.v3i0.7852
Abstract: There is no information on what exactly quality is as perceived by the public as the potential recipients of education programs to guide policy makers to deliver quality. This study explored the determinants of quality of education program as perceived by the public. This study is important because a quality concept starts from customers according to which the providers should develop their programs. Following the theory of customers’ perceptions, this study assessed stakeholders’ beliefs about quality of education program rather than objective reality that organizations offer as quality education. Through a survey on about 220 respondents and corresponding data analysis, this study found out the determinants of perceived quality of education with special reference to MBA programs in Nepal. The variables included in this study were quality of faculty, quality of infrastructure, graduate employability, curriculum and reputation as antecedents of perceived quality and perceived value. This study found out that perceived quality is determined by reputation of the program as credible and trustworthy which is influenced by graduate employability, practical curriculum and competent faculty.

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.38132
Abstract: Acid lime (Citrus aurantifolia) fruits are cultivated in terai, mid hill and high hill districts of Nepal. It is cross-pollinated crop and has a high variation in fruit characters within the species. Fruit character is the main basis of genotype selection. Study of fruit diversity is of utmost importance to select the elite genotypes for breeding and variety development program. Therefore, total of 620 fruit samples were collected and evaluated in the main production season of the year 2010 and 2011, from 62 bearing trees. Samples were collected from three agro-ecological domains, representing terai, mid hill and high hill areas of eastern Nepal. Elite landraces were selected on the basis of scoring fruit characters. High variation in vitamin C was observed between the terai (57.4 mg) and high hill (72.5 mg) samples. Amount of juice was 36.8% in mid hill and 44.1% in terai samples. Higher percent of juice and total soluble solids (TSS) observed in terai samples but tritable acidity (TA) and vitamin C was low as compare to high hills. There was significantly negative correlation found in fruit weight, fruit diameter, juice percent and seed number, whereas significantly positive correlation was in pulp and vitamin C, with altitude range. Total landraces were separated in five major cluster group. Variation in the level of similarity was observed among the cluster groups. The variability distance of fruit characters was highest in cluster group II (–17.45%) and lowest in cluster group V (58.5%). On the basis of scoring number of fruit characters, total four elite genotypes i.e. LD-49 from mid hills, LD-23 and LT-17 from higher hills and LM-44 from terai were selected for conservation, breeding and variety development purpose.

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.312204
Abstract: Acid lime (Citrus aurantifolia) is an important commercial fruits crop, cultivated in terai to high hills of Nepal. High variation of acid lime fruits are observed in existing landraces due to crossing within the other citrus species. Determination of genetic variation is important to the plant breeders for development of high yielding variety and hybrids. Therefore, an attempt has been made to study the genetic diversity of 62 acid lime landraces, collected from different altitudinal range in the eastern part of Nepal, using SSR markers. Twelve Simple Sequence Repeat (SSR) primer pairs were used to assess the genetic diversity of acid lime. The average genetic similarity level among the 62 accessions was 0.77, ranging from 0.54 to 1.0 and separated five major cluster groups. Total of 33 alleles were detected by eleven primer pairs and size of alleles ranged from 50 to 225. Average polymorphic information content (PIC) value was 0.50, whereas highest 0.75 and lowest 0.18 was observed in CAT01 and GT03 loci respectively. The results of the study clearly indicated that, SSR markers are highly polymorphic and more informative for the assessment of genetic diversity of acid lime landraces.

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.312206
Abstract: Acid Lime (Citrus aurantifolia Swingle) is one of the important commercial fruits cultivated from terai to high hill of Nepal. It is an important source of vitamin “C” (ascorbic acid) for human nutrition. Amount of juice, TSS (Total soluble solids), TA (Titrable acid) and vitamin C are the determining factors of quality of acid lime fruits which may vary according to bearing sides of the trees. The main objective of this study is, to determine the variation of fruit quality at different sides of the tree. Total of 15 bearing trees were selected randomly (5 trees per site) from three different agro ecological domain representing terai (<600 m asl), mid hills (600 to 1200 m asl) and high hill areas (>1200 m asl) and samples were collected from the selected trees. Randomly ten fruits (from east, west, centre, north and south sides) were collected from each tree and analyzed for amount of vitamin C, TSS, TA and juice. Highest ascorbic acid 79.6 mg and 69.9 mg was observed in south side fruits whereas lowest 62.8 mg and 55.1 mg was observed in centre fruits in the high and mid hills zone respectively, but in terai, highest ascorbic acid 58.7 mg was observed in north side and lowest 41.8 mg was observed in centre. Highest amount of juice 43.9% was observed in south side fruits and lowest 36.6% in centre fruits, but amount of TSS 8.2% and TA 7.2% was observed in south side fruits and lowest 7.3% TSS and 7.0% TA was observed in centre fruits in high hills. In terai highest TSS 8.3% and TA 7.4% was observed in north side fruits and lowest TSS 7.3% and TA 6.7% was observed in centre fruits. Variation of TSS, TA percent and ascorbic acids was observed according to the agro ecological zone.
Simulation of Spread and Control of Lesions in Brain

Computational and Mathematical Methods in Medicine , 2012, DOI: 10.1155/2012/383546
Abstract: A simulation model for the spread and control of lesions in the brain is constructed using a planar network (graph) representation for the central nervous system (CNS). The model is inspired by the lesion structures observed in the case of multiple sclerosis (MS), a chronic disease of the CNS. The initial lesion site is at the center of a unit square and spreads outwards based on the success rate in damaging edges (axons) of the network. The damaged edges send out alarm signals which, at appropriate intensity levels, generate programmed cell death. Depending on the extent and timing of the programmed cell death, the lesion may get controlled or aggravated akin to the control of wild fires by burning of peripheral vegetation. The parameter phase space of the model shows smooth transition from uncontrolled situation to controlled situation. The simulations show that the model is capable of generating a wide variety of lesion growth and arrest scenarios.

International Journal of Pharmacy and Technology , 2010,
Abstract: The hepatoprotective activity of methanolic extract of Solena amplexicaulis (SAME) (Lam.)Gandhi (Cucurbitaceae) at doses of 250 mg/kg and 500 mg/kg were evaluated by carbon tetrachloride(CCl4) intoxication in rats. The toxic group which received CCl4 (0.3 ml/kg of CCl4 dissolved in 1:1 ratio in olive oil by subcutaneous (s.c) alone exhibited significant increase in serum alanine aminotransferase(ALT), aspartate amino transferase (AST), alkaline phosphatase (ALP) and total bilirubin (TB) levels. It also caused significant (P<0.001) decrease in protein levels. The groups receivedpretreatment of SAME at a dose of 500 mg/kg b.w.p.o. had controlled the AST, ALT, ALP and total bilirubin levels and the effects were comparable with standard drug (silymarin 100 mg/kg b.w.p.o).The total protein (TP) and albumin (ALB) levels were significantly increased in the animals received pretreatment of the extract at the higher dose level. The animals received pretreatment of the extractshown decreased necrotic zones and hepatocellular degeneration when compared to the liver exposed to CCl4 intoxication alone. Thus the histopathalogical studies also supported the protective effect ofthe extract.
