Agronomy Journal of Nepal , 2011, DOI: 10.3126/ajn.v2i0.7525
Abstract: A set of eight rice ( Oryza sativa L.) genotypes in upland condition were evaluated in Bhajhang district. They were compared with popular local and standard check varieties of upland rice with an objective of selecting them to be suited to Bhajhang and similar agro-ecological domains. The genotypes included were; Tauliya, Chhomroung, Kalo Nathre, Rato Ghaiya, Pakhe Jhinuwa, Radha- 32, IR78877-208-B-1-2, and CT- 65110-24-1-1. They were evaluated in a Randomised Complete Block Design (RCBD) with four replication at Rayal VDC-3, Deura, Bajhang, Nepal during 2010 upland paddy growing season. Highly significant variation was observed for traits recorded. Grain yield ranged from 2.1 kg/plot (Radha- 32 and Rato Ghaiya) to 0.52 kg/plot (Pakhe Jhinuwa). Radha- 32 and Rato Ghaiya were found superior to Local checks. Likewise, significant variation was also observed in the morpho-physiological traits such as days to anthesis and days to maturity which varied from 100 days (Tauliya) to 114 days (CT 65110-24-1-1) and 126 days (Tauliya) to 148 days (CT 65110-24-1-1), respectively. Genotype Tauliya was early maturing while CT 65110-24-1-1 was late maturing one. There was a variation in grain filling period which ranged from 24 days (Pakhe Jhinuwa) to 36 days (Chhomroung and IR 78877-208-B-1-2) after anthesis to physiological maturity. Similarly, significant variation was also recorded for plant height, panicle length, and peduncle length. Highly significant positive correlation (r = 0.85, 0.69, 0.54 and 0.83) was found for panicle length, peduncle length, grain filling period and numbers of grains/panicle with grain yield. Likewise, significant positive correlation was found between days to maturity and grain filling duration (0.81), numbers of grains/panicle and panicle length (0.81), 1000 seeds weight, and grain filling duration (0.53). The result of the study revealed that Radha- 32 and Rato Ghaiya were found as the best genotypes so far as farmers and breeders are concerned in the tested site of Bajhang.

Abstract: The ability of a pavement structure in carrying out its function reduces in line with the increase of traffic load, especially if there are overloaded heavy vehicle passing through the road. This study was done to know the effect of overloading vehicles on the road pavement and remaining service life of the pavement. In this study, the service life of pavement due to overloaded vehicles was analyzed using the AASHTO 1993. In Narayanghat-Mugling road the composition of traffic seems to be 83.76% heavy vehicles, 9.18% medium vehicle and 7.05% light vehicle. For the direction of Narayanghat-Mugling, the pavement service life might be reduced by 59.90% due to overloading condition, while for the opposite direction, the service life would not reduced caused by the same factor. The impact of overload conditions on the road pavement showed premature failure; that is, a condition which the damage reduced the life of roads before the design life of the road is reached. From the results, it can be concluded that overloaded vehicles on the road are very influential to the reduction in pavement service life. Therefore, it is expected that road users to comply with existing regulations in the conduct of transportation. As overloading is increasing, it has to be controlled by rules and regulations with penalty to control the overloading. So fines must be associated with intensified enforcement when considered in further strategy. Regular monitoring, inspection and enforcement are the effective ways to control overloading. Use of technology (Automatic overloading information system) may be the effective way to control the overloading.

Agronomy Journal of Nepal , 2013, DOI: 10.3126/ajn.v3i0.9020
Abstract: Nepalese yellow maize inbred lines were characterized for general combining ability (GCA) and specific combining ability (SCA) of their crosses and parents were identified having high combining ability for determining the heterotic effects on yield and other quantitative traits of hybrids. A line x tester mating design was used for making the crosses in the winter season of 2008 and the hybrids along with their parents and four checks were evaluated in Randomized Complete Block Design (RCBD) with three replications in the spring season of 2009 at the experimental farm of the National Maize Research Program, Chitwan. Significant variations were found among the treatments for grain yield and other traits which indicated presence of high magnitude of genetic variations among tested inbred lines. The cross between RML-32 and RML-17 produced the highest grain yield (15870 kg/ha) among the crosses. Hybrids such as RL-194 x RL-84 (10770 kg/ha), RML-21 x RML-17 (9270 kg/ha), RL-180 x RML-17 (9270 kg/ha) and L-1 x RL-84 (8785 kg/ha) were found superior grain yielder. Thirty-nine hybrids showed positive mid-parent heterosis for grain yield among 40 crosses. The highest positive mid-parent heterosis for grain yield was found 880% in cross between RML-32 and RML-17, followed by RL-98X RML-17 (507%), RL-103 x RML-17 (403%), PUTU-18 x RML- 17 (351%) and RL-180 x RL 84 (316%).

Abstract: Pitavastatin belongs to the class of coenzyme A reductase inhibitors. Very few methods of assaying pitavastatin from human plasma are available in literature. An analytical method is presented for the determination of the drug from human plasma making use of the fluorescent property of the drug. The drug is extracted from plasma using ethyl acetate under neutral condition and then analyzed by reversed-phase high performance liquid chromatography (HPLC) with fluorescence detection (lambda(Ex) 245 nm; lambda(Em) 420 nm). Analysis of pitavastatin was carried out on a C18 HPLC column using a gradient flow of mobile phase (0.01 mol/L monobasic potassium phosphate (pH 3.20) -acetonitrile, 63:37, v/v). Fluorescein isothiocyanate was used as internal standard. The dynamic range of assay was 3 to 50 ng/mL. The intraday precision was less than 10% and accuracy ranged from 95.2% to 112.6%. The same for interday check was less than 12% and 92.8% to 105.1%, respectively. The drug was found to be stable under the assay conditions. The developed method is simple, precise, accurate, and stable. This indicates that it can be applied to routine analysis of this drug in human subjects where there are large numbers of samples without the need of specialized instruments like column switching.
Semantic Sentence Similarity Using Finite State Machine  [PDF]
Chiranjibi Sitaula, Yadav Raj Ojha
Intelligent Information Management (IIM) , 2013, DOI: 10.4236/iim.2013.56018

In this paper, a finite state machine approach is followed in order to find the semantic similarity of two sentences. The approach exploits the concept of bi-directional logic along with a semantic ordering approach. The core part of this approach is bi-directional logic of artificial intelligence. The bi-directional logic is implemented using Finite State Machine algorithm with slight modification. For finding the semantic similarity, keyword has played climactic importance. With the help of the keyword approach, it can be found easily at the sentence level according to this algorithm. The algorithm is proposed especially for Nepali texts. With the polarity of the individual keywords, the finite state machine is made and its final state determines its polarity. If two sentences are negatively polarized, they are said to be coherent, otherwise not. Similarly, if two sentences are of a positive nature, they are said to be coherence. For measuring the coherence (similarity), contextual concept is taken into consideration. The semantic approach, in this research, is a totally contextual based method. Two sentences are said to be semantically similar if they bear the same context. The total accuracy obtained in this algorithm is 90.16%

Anil Ojha
Journal of Nepal Paediatric Society , 2013, DOI: 10.3126/jnps.v33i2.8314
Abstract: Introduction: Ayurvedic remedies are popularly used in practice for long time in Nepal. It is regarded as safe and free from side effects. However there are published reports of the high content of heavy metals like lead in such preparations. No such study has been done in Nepal looking at the lead content in ayurvedic preparations. The aim of this study was to detect the level of lead in commonly used ayurvedic remedies used in paediatric population if any. Materials and Methods: Seventeen samples were selected for lead estimation based on frequency of prescription and over the counter dispense. All of them were analyzed using Atomic Absorption Spectrophotometer (AAS) 6300 using flame mode. Results: None of the samples had detectable level of lead in parts per billion. Conclusion: Though this study did not detect lead in the seventeen samples of ayurvedic medicine, a larger study is needed involving large samples of these medicines with use of more sensitive equipment for testing.

Journal of Institute of Medicine , 2012, DOI: 10.3126/joim.v34i2.9053
Abstract: Introduction: Placenta previa is one of the major causes for maternal morbidity and mortality. The aim of this study was to analyze the obstetrical factors associated with placenta previa and to find out the maternal and perinatal outcome of these cases. Methods: This was a retrospective study conducted in the Department of Obstetrics and Gynecology of TUTH. Hospital chart records of four years (1st January 2008 to 31st December 2011) were collected. Chart records of all women who had undergone cesarean section for placenta previa were reviewed. Relevant clinical findings were noted. Results: During the study period, there were 82 cases of cesarean sections done for placenta previa, which is 0.55% of the total deliveries. Of the eighty two cases, charts could be obtained of the 70 patients for the analysis. 21.4% had total placenta previa. Maximum women were in age group 26-30 years. Sixty one percent of the patients were multipara. Sixteen patients had history of cesarean section and 20 cases had abortions in previous pregnancy. Malpresentation was present in more than one fifth (21.4%) of the patient. 45.7% of the babies were preterm and 27% were low birth weight babies. Seven babies had neonatal death. Almost one third (31.4%) of the patient had blood loss ≥500ml. There were four cases with blood loss ≥1000ml. Among them two had loss of more than two liters. Ten patients required blood transfusion. One patient had cesarean hysterectomy. Conclusion: Placenta previa poses danger to both the mother and the baby. There is high maternal morbidity and adverse perinatal outcome.

Kinematical Properties of the Thick Disk of the Galaxy
Devendra Ojha
Physics , 1994,
Abstract: We try here to find new constraints on thick disk population using samples at intermediate latitude and North Galactic Pole, which include photometry and proper motions. The algorithm SEM (Stochastic-Estimation-Maximization; Celeux \& Deibolt 1986) was used to deconvolve the stellar components up to large distances above the plane, allowing to study of their statistical properties independently. The multivariate discriminant analysis (MDA) is used to qualify the thick disk using observations in multidimensional space (V,B-V,U-B, $\mu_{l}$ \& $\mu_{b}$).
Parsec-scale structure of quasars: dawn of the golden age?
Roopesh Ojha
Physics , 2013,
Abstract: Half a century after their discovery, the study of quasars remains one of the most fascinating intellectual challenges in astronomy. Quasars are laboratories for everything from relativity to magnetohydrodynamics and are perhaps the best available probes for cosmology. A tremendous amount has been learned about quasars and yet many of the most fundamental questions about their physics remain open. Parsec-scale observations have played an indispensable role in building up our current understanding of quasars; virtually everything we know about quasars depends on such observations. However, the finest hour for parsec scale observations may be just beginning. This is partly due to the development of highly reliable VLBI networks (which is continuing) but mostly due to the unprecedented availability of multiepoch, simultaneous, broadband observations that have long been the `holy grail' for quasar researchers.
A Novel Service Oriented Model for Query Identification and Solution Development using Semantic Web and Multi Agent System
Muneendra Ojha
Computer Science , 2012, DOI: 10.5120/4428-6165
Abstract: In this paper, we propose to develop service model architecture by merging multi-agentsystems and semantic web technology. The proposed architecture works in two stages namely, Query Identification and Solution Development. A person referred to as customer will submit the problem details or requirements which will be referred to as a query. Anyone who can provide a service will need to register with the registrar module of the architecture. Services can be anything ranging from expert consultancy in the field of agriculture to academic research, from selling products to manufacturing goods, from medical help to legal issues or even providing logistics. Query submitted by customer is first parsed and then iteratively understood with the help of domain experts and the customer to get a precise set of properties. Query thus identified will be solved again with the help of intelligent agent systems which will search the semantic web for all those who can find or provide a solution. A workable solution workflow is created and then depending on the requirements, using the techniques of negotiation or auctioning, solution is implemented to complete the service for customer. This part is termed as solution development. In this service oriented architecture, we first try to analyze the complex set of user requirements then try to provide best possible solution in an optimized way by combining better information searches through semantic web and better workflow provisioning using multi agent systems.
