Stock price forecasting in the field of interest for many stock investors to earn more profit from stock trading. Nowadays, machine learning researchers are also involved in this research field so that fast, accurate and automatic stock price forecasting can be achieved. This research paper evaluated GRU network’s performance with weight decay reg-ularization techniques for predicting price of stocks listed NEPSE. Three weight decay regularization technique analyzed in this research work were (1) L1 regularization (2) L2 regularization and (3) L1_L2 regularization. In this research work, six randomly selected stocks from NEPSE were experimented. From the experimental results, we observed that L2 regularization could outperform L1 and L1_L2 reg-ularization techniques for all six stocks. The average MSE obtained with L2 regularization was 4.12% to 33.52% lower than the average MSE obtained with L1 regularization, and it was 10.92% to 37.1% lower than the average MSE obtained with L1_L2 regularization. Thus, we concluded that the L2 regularization is best choice among weight regularization for stock price prediction.

All sciences, including biological science, have uncertainty, and they complicate theoretical questions. Uncertainty essentially is a mark of good science, and its efficacious communication is even essential for better decisions. Explaining the research work uncertainties indicates that the scientists are aware of the vital difference between the known and the unknown. Uncertainty is equally significant in biodiversity studies. Species composition of any area can’t be predicted with certainty because of interwoven relationships between species diversity and climatic and anthropogenic factors. Good survey planning with acceptable animal welfare practices could lead to asymptote for inventory of any particular area. Scientists can handle uncertainty in their studies by sensible statistics and reasonably large sample size.

Wetlands are considered the most diverse and productive ecosystems in the world, providing life-sustaining ecological services. Hydrochemical variables of the Ghodaghodi Lake situated in Far west Nepal were studied using multivariate statistical approaches to investigate the characteristics of water quality of the lake. A total of 10water samples were collected and analyzed for water temperature, pH, electrical conductivity, total dissolved solids, total hardness, salinity, dissolved oxygen, major ions, and dissolved Si in the pre-monsoon season during 2017.The water quality assessment was carried out by applying sodium percentage, sodium adsorption ratio, permeability index, Kelly’s ratio, magnesium adsorption ratio, action ratio of soil structural stability, and water quality index. Multivariate statistical techniques were used to evaluate the geochemical and anthropogenic processes and to identify factors influencing the ionic concentrations. The results revealed that the water was slightly alkaline with low ionic strength and remarkable spatial variations. The hydrochemistry of the lake was mainly controlled by rock weathering as the dominant Ca2+-HCO3- facies. The principal component analysis provided three major components exhibiting the diverse sources of natural and anthropogenic chemicals, including agricultural fertilizers, leakage of sewages near the human settlements, etc. The measured hydrochemical parameters indicate that lake water lies within the safe drinking water and irrigational standards. However, special consideration should be taken to control the concentrations of NO3- due to increasing anthropic activities.

This study has analysed the factors of production, viz; agricultural land, working force and gross fixed capital formation (GFCF) of Nepal between 2000/01-2017/18 AD and has determined their effects on national income, viz; Gross Domestic Product (GDP) by using Cobb-Douglas regression function. The results showed an average growth rate of GDP, agricultural land, working force and GFCF to be 3.9%, 0.8%, 1.5% and 7.9%, respectively, with the values plummeting in 2015/16, due to occurrence of the devastating earthquake in 2015, but then again variable values skyrocketed following years. The regression analysis found that GDP was affected significantly by agricultural land and working force, but insignificant with GFCF. On an average, with the increase in agricultural land and working force by 1 %, GDP increased by 1.1% and 1.7%, respectively. Thus, policy regarding an increment of agricultural land use and employment of labour force must be framed to improve the Nepalese economy.

It was mainly due to Atkinson works, who introduced Linear Multiparameter Eigenvalue problems (LMEPs), based on determinantal operators on the Tensor Product Space. Later, in the area of Multiparameter eigenvalue problems has received attention from the Mathematicians in the recent years also, who pointed out that there exist a variety of mixed eigenvalue problems with several parameters in different scientific domains. This article aims to bring into a light variety of scientific problems that appear naturally as LMEPs. Of course, with all certainty, the list of collection of applications presented here are far from complete, and there are bound to be many more applications of which we are currently unaware. The paper may provide a review on applications of Multiparameter eigenvalue problems in different scientific domains and future possible applicatios both in theoretical and applied disciplines.

Ageing is a natural process. The elderly population is increasing in Nepal.When there is presence of diseases, physical inability, and financial harshness, the elderly in Nepal have to face many problems. This study was thus conducted to assess the socio-economic milieu and spectrum of gynaecological problems among women living in old age homes of Kathmandu valley. For this a cross sectional study was conducted in 21old age homes of three districts of Kathmandu valley. In this study, they were 234 particants. Privacy and confidentiality of information about the individual were strictly maintained. One-third of the aged women living in the old age homes belonged to 70-80 years.50.9% were from outside Kathmandu valley, while 49.1% were from the valley. The elderly were mostly not visited by their relatives and friends. Most of them (74.4%) were interested in praying than other activities. Out of the total Urine samples (190), 68.4% were normal, and 9.4% had a urinary tract infection. There were only 15.6% uterine prolapse cases. Out of total, 70.9% of Pap smear report was normal, while 25.1% had inflammatory smear. This study revealed that the old age homes have become a shelter for most of elderly women. The socio-economic condition was poor. Gynaecological probems like UTI, Urinary incontinence were not high but the prolapse cases (uterine proplase, cystocele, rectocele) were remarkably high. Cervical cancer screening through Pap smear showed negative results.

Co-infection with other respiratory pathogens has been reported in patients with COVID-19. Common respiratory pathogens can infect as co-pathogens during SARS-nCoV-2 infections. The aim of this article is to spread knowledge regarding possible co-infections during COVID-19, and reduce their occurrence. Google scholar was used to search the literature for possible co-infections in the people with COVID-19 and reviewed the existing published data. In most cases, co-infections are common due to Streptococcus pneumoniae, Staphylococcus aureus, Klebsiella pneumoniae, Mycoplasma pneumoniae, Chlamydia pneumonia, Legionella pneumophila, and Acinetobacter baumannii.Prevalence of fungal and viral co-infections is low. However, Candida species and Aspergillus flavusare the common co-infective fungi. Viruses such as Influenza, Corona virus, Rhinovirus/ Enterovirus, Parainfluenza, Metapneumo virus, Influenza B virus, and Human immunodeficiency virus have also been reported as co-infecting agents during COVID-19. Influenza A was one of the most common co-infective viruses, which may have caused initial false-negative results of a real-time RT-PCR for severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). The prevalence of co-infections could be up to 50% among non-survivors. Only newly developed syndromic multiplex panels that incorporate SARS-CoV-2 may facilitate the early detection of co-infections. The suitable antimicrobial agents can be recommended for the co-infections caused by other respiratory pathogens during COVID-19.

The application of silver nanoparticles in various sectors including health related field is remarkably profound. Nowadays, the research of synthesizing metal nanoparticles (MNPs) using plant extracts is fascinating field as it offers the eco-friendly and cost-effective method for nanoparticle synthesis. In this study, we synthesized silver nanoparticles (AgNPs) using methanolic extract of B.asiatica and C. fistula regarding their ethnomedical importance. The synthesized AgNPs were characterized by UV-Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR) and X-ray diffractometer (XRD). UV-vis spectroscopy exhibited the characteristic Surface Plasmon Peak of silver nanoparticle~420 nm.FTIR data were measured to get a preliminary idea on the functional groups responsible for the stabilization of AgNPs. XRD data confirmed the natural crystal structure with a face centered cubic of AgNPs. The antibacterial activity of biosynthesized AgNPs was assessed by testing promptly available gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacterial strain and antioxidant activity was calculated by DPPH assay. The overall outcomes of the studies concluded that the application of the biogenic synthesis of AgNPs of B. asiaticaas an antioxidant and antibacterial agent is more potent showing IC50 value 65.1±1.30 μg/mL and the highest zone of inhibition 15 mm in diameter against S. aureus.

An experiment was conducted to evaluate the effects of hydroponics maize fodder on growth and nutrient digestibility of weaned piglets from July 1st, 2017 to August 11th, 2017, for six weeks. The experiment consisted of 75 days old, 15 crossbreed piglets (Duroc x Nagpuri & Duroc) in a Completely Randomized Design with three treatments and five replications. Treatment 1 (T1) contained 100% concentrate feed, Treatment 2 (T2) 90% concentrate feed and 10% hydroponics maize fodder and Treatment 3 (T3) 80% concentrate feed and 20% hydroponics maize fodder in the diet. The study revealed that hydroponics maize fodder contained DM 13.80%, CP 12.54%, NDF 47.04%, and ADL 16.51%. The treatments had non-significant effect (P > 0.05) on daily weight gain, final weight and feed conversion ratio of the piglets. However, piglets fed with 90% concentrate and 10% hydroponics maize fodder had the highest final weight (35.8±5.0 kg), while the lowest (33.6±5.00 kg) was recorded in piglets fed with 80% concentrate and 20% hydroponics maize fodder. The cost of hydroponics maize fodder production was Rs. 20.62 per kg, which was higher than the cost in the Indian context. The difference in Feed Conversion Ratio (FCR) was also not significant. However, piglets fed with T2 (1:2.58) diet recorded higher FCR than T3 (1:2.56) and T1 (1:2.51). In conclusion, the inclusion of hydroponics maize fodder in piglets diet appeared promising in growth, nutrient digestibility and cost of production.

In conclusion, the inclusion of hydroponics maize fodder in piglets diet appeared promising in growth, nutrient digestibility and cost of production.","PeriodicalId":129302,"journal":{"name":"Nepal Journal of Science and Technology","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133338379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A field experiment was conducted at Horticulture Research Station (HRS), Dailekh, in Mid-Western hills of Nepal during 2019 and 2020, to evaluate the performance of ten potato genotypes for plant, and tuber yield characters. The potato genotypes were evaluated during spring season in a randomized complete block design with three replications. The genotypes showed highly significant difference for all the traits except tuber emergence. The mean squares for the year were also significant for all the traits except tuber emergence, stem numberplant -1 and total tuber yield. The interaction between genotypes and years did not show significant differences in all the traits except stem numberplant -1. Genotype CIP392797.22 produced more marketable yield (27.5 tha -1) and total tuber yield (30.2tha -1) than all other genotypes. The genotype CIP392797.22 is characterized as medium maturing, oval-shaped and dark red-skinned one with shallow eye depth in the tuber, and it imparted 13.2% higher marketable yield than Kufri Jyoti (24.3 tha -1). Thus, the genotype CIP392797.22 is recommended to evaluate on-farm for the verification and up-scaling among farmers at Mid-Western Nepal.
