Udaya Raj Paudel, Rajesh Gupta, Sameen Poudel, Kabita Adhikari
Advances in Literary Study (ALS) , 2018, DOI: 10.4236/als.2018.64016
Abstract: Communication, political party perception and voting behavior of the people keep congenial nexus. Grounded on this bond, the main purpose of this study is to analyze the factors that impact political party perception and voting behavior of the people in Nepal from the perspective of communication, particularly residing on social networking sites: Facebook, Twitter and YouTube. In purposive sampling method perception level detailed data were obtained from 333 respondents aged 20 years and above just before the historic constitutional assembly election in Nepal. A set of questionnaires including multiple choices and Likert scale questions were provided to obtain the information. Drawing the coherent substance from Technological Determinism, Social Judgment, Agenda Setting, Uses and Gratification, and Habermas’s Concept of Public Sphere and Political Campaign theories, the research explores the roles of social media in political party perception and voting behavior. The results show that political interest is positively related to political party perception and voting behavior, which infer that political party perception is influenced by political interest of the politician. The analysis also indicates that political trust is also positively related to political perception and voting behavior, which shows that political trust highly influences political party perception. Likewise, religion and social media are also positively related to political party perception and voting behavior. The study roots on primary source of data and contributes to understand the impact of social media in the society and politics.
On Farm Conservation of Crop Genetic Resource: Declining De Facto Diversity and Optimal Funding Strategy  [PDF]
Diwakar Poudel
Natural Resources (NR) , 2015, DOI: 10.4236/nr.2015.63018
Abstract: Crop genetic resources (CGRs) are crucial natural resource which ensure food or livelihood security of billions of people today as well as ensure future agricultural innovations. However, the CGR diversity remaining in in situ, particularly in subsistence farming is becoming extinct due to change in economic and technological development over time. An optimal funding strategy is required for conservation of these CGRs. In this paper, I have discussed an economic perspective on why and how the De Facto crop genetic resources (CGRs) diversity declines with changing economic and environmental context. The model maximizes the net revenue from the farmers land allocation strategy to different CGRs under economic and technical constraints with linear demand and cost functions. Furthermore, the model suggests how to minimize the cost of on farm conservation of these crop genetic resources in situ (or ex situ) without forfeiting farmer’s well-being in a changing perspective of economics and technology. The theoretical model developed in this study is employed to demonstrate the applicability for on farm conservation of rice genetic diversity in Nepal. The study suggests an optimal fund allocation strategy that minimizes the cost of conservation by (i) identifying particular CGRs (rice landraces) that are prone to extinct from the community and (ii) categorizing the farmers in the community having minimum cost of conservation for those particular landraces. As the model maximizes the farmers’ revenues, it could ensure better livelihood of individuals in the community while minimizing the cost of in situ conservation of biodiversity on farm.

Laxman Poudel
International Journal of Engineering Innovations and Research , 2012,
Abstract: A study is done to develop fluvial particle monitoring system based on application of spectral imaging, image processing and artificial neural network. Research in this field has been initiated from 2004 at Kathmandu University. This research is applied to Bagmati river which is the principal river flowing and draining across Kathmandu Valley. Fluvial particles of Bagmati River were continuously monitored at 18 different strategic locations. These samples were continuously monitored in the Lab of Machine Vision at Kathmandu University in separate pre-monsoon, monsoon and post-monsoon seasons of 2011. A lab set up equipped with image processing and spectral imaging is developed to monitor the contents of fluvial particles. The set up resembles as a river path that contains upper reservoir and lower reservoir and a special transparent flow cell fabricated in between to monitor the particles instantaneously. An application is developed to characterize the particles that run on computer using Matrox imaging Library software and Mat lab 6.5 environments. The samples were taken in standard 125 millilitre jar. It characterizes organic and inorganic according to the spectral signature of the particles trained with Artificial Neural Network. Organic particles have different signature than that of inorganic and are most distinct at 630 and 670nm wavelength. Based on these characterizing properties samples from 18 strategic locations of Baghmati rivers were characterized. Reflectance property is used to characterize particles with Perceptron neural network and hardlim as a transfer function. The result depicted that the ratio of organic to inorganic is found to be 0.1111 at upstream of Sundarijal, 0.13889 at Guyeswori and 0.16 at Chobhar according to weight basis. Chobhar is the spot with high amount of both organic and in-organic contents. According to particles count the ratio of organic to inorganic is found to be 0.02362 at upstream of Sundarijal, 0.02955 at Guyeswori and 0.034576 at Chobhar. So this result shows that this system can be applied for water particles monitoring. This system can be used to find out the socio-economic activities at different points, suitable waste-water treatment plant area, irrigation and aquatic life preservation.
Application of Digital Image Processing for Shape Characterization of Sand Particles
Laxman Poudel
International Journal of Engineering Innovations and Research , 2012,
Abstract: This part of research work is focused on defining sand particles shape using Digital Image Processing (DIP). Sand particles shape can be defined using geometrical structures which involves mathematics and its derivatives. Shape descriptor is utilized to define exactly the sand particles shape. It describes the region or boundary of sand particles. So study of sand shape using digital image processing with Fourier analysis gives an exact particles shape. This research utilizes nondestructive automation technique online or off-line based on using image processing. It is revealed that total 21 different shape of sand particles were identified each having different measures. Sand shapes were analyzed and processed using Charge Coupled Devices (CCD) camera, image processing Matrox Imaging Library (MIL) Software and in MatLab 6.5 platform. This new way of vision which cannot be revealed by eye can characterize particles shape easily. Research in shape similarity has a lot of challenges, some solutions and, and for same in use in different application.
Effect of Sediment Size in Hydraulic Turbine Material: A Case Study of Roshi Khola in Nepal
Laxman Poudel
Nepal Journal of Science and Technology , 2012, DOI: 10.3126/njst.v13i2.7725
Abstract: Siltation problem in Nepal is major and challenging in hydropower development. It degrades the reservoir capacity and hydraulic turbines’ efficiency. Many researches have been carried out in this field and have proven sand as major substance that erodes the turbine material, but only few researches have accounted every parameters of sand on degradation of hydraulic turbines. This paper accounts size of sediments important parameter that has direct impact on turbine material. Sediment size impact has been studied firstly by characterizing size into six layered using sieve analyzer and testing its impact using high velocity test rig at Kathmandu University. Sand samples from 20 different stations of Roshi river were collected and tested on turbine material 18Cr4Ni. It found that greater micron sizes of sediments have great impact was than relatively smaller ones. It is depicted that 300-400 micron size sediment, have highest impact with weight loss of 0.022 milligram, 212-300 micron size has 0.013 milligram weight loss, 90-212 micron size has 0.012 and below 90 micron sizes have 0.0075 milligram of weight loss.

Kyphotic deformity in pott’s spine
Sushil Poudel
Journal of Kathmandu Medical College , 2013, DOI: 10.3126/jkmc.v2i4.11790
Abstract: Kyphotic deformity is a well-known complication in spinal tuberculosis patients. This deformity, which is seen in 15% of patients treated conservatively, progresses in two phases: Phase I, which includes the changes in the active?phase, and Phase II, which includes changes after the disease is cured. Factors influencing deformity progression are severity of the angle before treatment, the level of the lesion, and age of the patient. Adults have an increase less than 30? during the active phase with no additional changes in the healed phase. During the growth spurt of the children, there is worsening of the deformity in 39% (Type I), an improvement in 44% (Type II), and no change in 17% (Type III). Spine-at risk radiologic signs aid in early identification of the children at risk of late progressive deformity. Surgery for preventing deformity must be done earlier rather than later and in patients with severe disease.

BS Poudel
Banko Janakari , 2009, DOI: 10.3126/banko.v19i3.2205
Abstract: Wetlands are among the most productive but threatened ecosystems on earth. Wetlands provide many benefits - environmental, economic and social - yet there is a limited assessment of these multiple values and therefore, have little attention in national accounts. Nepal has been transforming its resource management policies in favor of local people. This paper reviews existing policy framework and legal mechanisms involved in wetlands. There are several acts and regulations which have direct or indirect bearing on wetland conservation and management. It also discusses issues and possibilities of wetland management in Nepal. Finally, it recommends capacity building, wetland survey and inventory. Key words: Wetlands, policies, plans, acts, Ramsar, ecosystem, values ?? doi: 10.3126/banko.v19i3.2205 Banko Janakari , Special Issue February 2009, 5-9
The thread of space, time and event: An implication in media studies
Krishna Poudel
Bodhi: An Interdisciplinary Journal , 2009, DOI: 10.3126/bodhi.v3i1.2815
Abstract: Recently widely circulated publications, the World Development Report 2009 of the World Bank (WB) and Human Development Report 2007/2008 of the United Nations Development Programmes (UNDP), have strongly emphasized the geographical space of the world. The World Development Report 2009 has a sub-title ‘reshaping the economic geography', whereas the Human Development Report has dealt on ‘fighting climate change, human solidarity in a divided world'. Both these documents have tried to disseminate a clear message about the interrelationship of geographical space and the human and natural processes, with special reference to functions and events associated in the contemporary world. The space is usually characterized by its elements of dimensionality, continuity, proximity and separation (NRC, 2006). Dimensions are components of a coordinate grid typically used to locate a point, line or area in a certain defined ‘space' as, for example, on the globe by latitude, longitude and elevation (X, Y and Z). In space-time, a coordinate grid that spans the 3+1 dimensions locates ‘events' (rather than just points in space), so time is added as another dimension to the grid, and another axis. This way, it is possible to plot where and when something is. Unlike in normal spatial coordinates, there are restrictions for how measurements can be made spatially and temporally. This is closely associated with the representation of events in the contextual ground of space and time. The representations can be made in a variety of modes and media (graphic [text, image or maps, and video], tactile, auditory, kinesthetic, and olfactory) to describe, explain, and communicate about the structure, operation, and function of objects and their relationships. Spatial thinking is not restricted to any domain of knowledge (NRC 2006). DOI: 10.3126/bodhi.v3i1.2815 Bodhi Vol.3(1) 2009 p.92-98
Lescop's Invariant and Gauge Theory
Prayat Poudel
Mathematics , 2013,
Abstract: Taubes proved that the Casson invariant of an integral homology 3-sphere equals half the Euler characteristic of its instanton Floer homology. We extend this result to all closed oriented 3-manifolds with positive first Betti number by establishing a similar relationship between the Lescop invariant of the manifold and its instanton Floer homology. The proof uses surgery techniques.
The bounds of the set of equivalent resistances of n equal resistors combined in series and in parallel

Physics , 2010, DOI: 10.1007/s12045-012-0050-7
Abstract: The order of the set of equivalent resistances, A(n) of n equal resistors combined in series and in parallel has been traditionally addressed computationally, for n up to 22. For larger n there have been constraints of computer memory. Here, we present an analytical approach using the Farey sequence with Fibonacci numbers as its argument. The approximate formula, A(n) ~ 2.55^n, obtained from the computational data up to n = 22 is consistent with the strict upper bound, A(n) ~ 2.618^n, presented here. It is further shown that the Farey sequence approach, developed for the A(n) is applicable to configurations other than the series and/or parallel, namely the bridge circuits and non-planar circuits. Expressions describing set theoretic relations among the sets A(n) are presented in detail. For completeness, programs to generate the various integer sequences occurring in this study, using the symbolic computer language MATHEMATCA, are also presented.
