        Wine Quality Evaluation Using Machine Learning Algorithms

        Xitiz Uniyal,Prashant Barthwal,Ashish Joshi 사단법인 미래융합기술연구학회 2017 아시아태평양융합연구교류논문지 Vol.3 No.4

        There are many prediction systems available for problems like stock exchange, medical diagnosis, insurance calculation, etc. Wine Quality is one area where there is a big opportunity to recommend a good quality of wine to users based on their preferences as well as in historical data. This paper describes the work to learn and assess whether a given wine sample is of good quality or not. The use of machine learning techniques specifically the linear regression with stochastic gradient descent were explored, and the features that perform well on this classification were engineered. The main aim is to develop a cost-effective system to acquire knowledge using data analysis through machine learning algorithms to predict the quality of wine in a better way.

        Composition and Structure of Himalayan Oak (Quercus leucotrichophora A. Camus) Forest under Various Degrees of Disturbance

        Prasad, Sunil,Uniyal, Pooja,Chauhan, D.S. Institute of Forest Science 2015 Journal of Forest Science Vol.31 No.1

        Forest disturbance sometime considered as a tool of management as it believed that mid level disturbance constructs better micro-climatic conditions which ultimately boost up the plant diversity. The effect of different levels of disturbance on species composition and regeneration is very important. Present attempt was carried out in a temperate evergreen oak forest which was under various degree of disturbance. The study area is one of the large ranges of oak forest in Garhwal Himalaya and compensating various types of daily needs of local people. On the basis of IVI values Quercus leucotrichophora holds first position in all the disturbance zones whereas Myrica esculenta upgraded it's rank in highly disturbed zone and showed less impacted species by disturbance. Berberis aristata and Eupatorium adenophorum in shrub layer and Anaphalis adnata and Bidens pilosa in herb layer were found as disturbance friendly species because they attained higher rank in highly disturbed zone whereas Caryopteris foetida was found disturbance-sensitive in shrub layer. The banj oak regenerated well under mid disturbance as compared to no and high degree of disturbance and a sharp downfall in the species diversity was recorded with increasing magnitude of disturbance. Density-diameter curves showed a reverse trend of lower density in higher girth classes. The results of the study should be useful for the forest management strategies.

        Assessment of Knowledge, Attitudes, and Practices of Parents/Caregivers Towards Migraine in Children: A Cross-Sectional Observational Study

        Rahul Sinha,Ankit Kumar Meena,Maneesh Uniyal,Sonali Singh,Ashish Upadhyay 대한소아신경학회 2024 대한소아신경학회지 Vol.32 No.1

        Purpose: This study aimed to evaluate the knowledge, attitudes, and practices (KAP) of parents or caregivers of children suffering from migraines at a tertiary care center in North India. Methods: We conducted a cross-sectional study involving 100 parents or caregivers, using convenience sampling. A 20-item questionnaire was administered in English and also translated into the local language (Hindi). The study included children with migraines who visited the pediatric outpatient department within a 6-month period (December 2022 to May 2023). Results: Over 60% of caregivers were aware of the chronic nature of the illness, its triggering factors, the role of family history, and the importance of lifestyle modifications. However, only 46% understood the pathophysiology of the illness, and 53% were aware of the medication used for childhood migraines. More than 85% of caregivers believed that recurrent headaches necessitate a doctor’s consultation, may require regular visits for optimal treatment, and were willing to alter their child’s lifestyle to prevent headaches. However, a significant percentage of caregivers (47%) practised self-medication for their children’s headaches. Most caregivers believed that lifestyle modifications and avoiding triggers were the best treatments for migraines. There were significant associations (P<0.05) between the level of education and responses to questions related to migraine definition, prophylaxis, treatment, investigations, lifestyle modifications, and screen time. Conclusion: Most participants were well-educated on migraine, and their KAP regarding migraine prevention and treatment were generally adequate. However, the practice of self-medication without professional guidance is a significant concern.

        Endoscopic Spine Surgery

        Choi, Gun,Pophale, Chetan S,Patel, Bhupesh,Uniyal, Priyank The Korean Neurosurgical Society 2017 Journal of Korean neurosurgical society Vol.60 No.5

        Surgical treatment of the degenerative disc disease has evolved from traditional open spine surgery to minimally invasive spine surgery including endoscopic spine surgery. Constant improvement in the imaging modality especially with introduction of the magnetic resonance imaging, it is possible to identify culprit degenerated disc segment and again with the discography it is possible to diagnose the pain generator and pathological degenerated disc very precisely and its treatment with minimally invasive approach. With improvements in the optics, high resolution camera, light source, high speed burr, irrigation pump etc, minimally invasive spine surgeries can be performed with various endoscopic techniques for lumbar, cervical and thoracic regions. Advantages of endoscopic spine surgeries are less tissue dissection and muscle trauma, reduced blood loss, less damage to the epidural blood supply and consequent epidural fibrosis and scarring, reduced hospital stay, early functional recovery and improvement in the quality of life & better cosmesis. With precise indication, proper diagnosis and good training, the endoscopic spine surgery can give equally good result as open spine surgery. Initially, endoscopic technique was restricted to the lumbar region but now it also can be used for cervical and thoracic disc herniations. Previously endoscopy was used for disc herniations which were contained without migration but now days it is used for highly up and down migrated disc herniations as well. Use of endoscopic technique in lumbar region was restricted to disc herniations but gradually it is also used for spinal canal stenosis and endoscopic assisted fusion surgeries. Endoscopic spine surgery can play important role in the treatment of adolescent disc herniations especially for the persons who engage in the competitive sports and the athletes where less tissue trauma, cosmesis and early functional recovery is desirable. From simple chemonucleolysis to current day endoscopic procedures the history of minimally invasive spine surgery is interesting. Appropriate indications, clear imaging prior to surgery and preplanning are keys to successful outcome. In this article basic procedures of percutaneous endoscopic lumbar discectomy through transforaminal and interlaminar routes, percutaneous endoscopic cervical discectomy, percutaneous endoscopic posterior cervical foraminotomy and percutaneous endoscopic thoracic discectomy are discussed.

        An experimental study on bioturbation and dung removal activities of Catharsius molossus (Linnaeus, 1758) (Coleoptera: Scarabaeidae) in the Greater Himalaya

        Amar Paul Singh,Kritish De,Virendra Prasad Uniyal,Sambandam Sathyakumar 국립중앙과학관 2021 Journal of Asia-Pacific Biodiversity Vol.14 No.2

        In this artice, we studied the bioturbation and dung removal activity of dung beetle Catharsius molossus(Linnaeus, 1758) (Coleoptera: Scarabaeidae: Scarabaeinae) in different elevations in the Great HimalayanNational Park Conservation Area for the first time to understand the capability of the species in providingsuch ecosystem services with an experimental approach in six different elevations in the area. We foundthat the weight of dung buried and bioturbation had significant difference between the elevations, andthey had significant linear relationship with the elevations. Differences in such activities along theelevation can cause a low amount of nutrient transfer from the dung to the soil which can adverselyaffect the surrounding habitats.

        Butterfly communities along an elevational gradient in the Tons valley, Western Himalayas: Implications of rapid assessment for insect conservation

        Manish Bhardwaj,Abesh K. Sanyal,Arun P. Singh,V.P. Uniyal 한국응용곤충학회 2012 Journal of Asia-Pacific Entomology Vol.15 No.2

        As time and money is limited, explicit, cost-effective, quick, and appropriate methods are needed to assist conservation planners and managers for making quick decisions. Butterflies promise to be a good model for rapid assessment and habitat monitoring studies because they are widespread, conspicuous, and easily recognizable and they are effective indicators of forest health. We conducted a rapid assessment of butterflies at five disturbance gradient sites that varied in elevation from 900 m a.s.l. to 3500 m a.s.l. for 20 days during March–April 2010 and recorded 79 butterfly species and 1504 individuals in the Tons valley in Western Himalayas. We were able to sample approximately 77% (123 species) of the estimated species richness on continuing the sampling until July 2010. Species richness at the study site is estimated to be 159 (95% CI:145–210) species. Diversity was highest in heterogeneous habitats and decreased towards homogeneous habitats. Unique species were highly restricted to lowest disturbed sites. Using Pearson's correlation analysis,the strongest vegetative predictors of butterfly richness were plant species richness, canopy cover, and herb and shrub density. Butterfly species richness and abundance were highly correlated with altitude, temperature,relative humidity, fire signs, and livestock abundance. We also found positive cross-taxon correlation among butterflies, moths, and beetles across sites, indicating that butterflies can be used as surrogate or indicator taxa for insect conservation. Short sampling periods providing comprehensive estimates of species richness were reliable for identifying habitats and sites with the most conservation value in the Tons valley landscape.

        Inhibition of monoamine oxidases by benzimidazole chalcone derivatives

        Krishna Athulya,Lee Jiseong,Kumar Sunil,Sudevan Sachithra Thazhathuveedu,Uniyal Prerna,Pappachen Leena K.,Kim Hoon,Mathew Bijo 한국응용생명화학회 2023 Applied Biological Chemistry (Appl Biol Chem) Vol.66 No.-

        Ten benzimidazole chalcone derivatives were synthesized, and their monoamine oxidase (MAO) inhibitory activity was evaluated. Most compounds showed higher inhibitory activity against MAO-B than MAO-A. Compound BCH2 exhibited an IC50 value of 0.80 μM, thereby showing the most potent inhibition amongst all. In addition, BCH2 showed the highest MAO-B selectivity index (SI) with an SI value of 44.11 compared to MAO-A. Among the substituents, the halogen group showed the best MAO-B inhibition, and the ortho-position of the B ring showed better inhibitory activity than the para-site. In comparison with ortho-substituents, the inhibitory activity increased in the order, -Cl > -Br > -F > -H. BCH2 was found to be a competitive inhibitor of the enzyme with optimum inhibition kinetics, where Ki was found to be 0.25 ± 0.014 μM. In the reversibility experiment, BCH2 showed a recovery pattern after MAO-B inhibition, similar to that of lazabemide. Thus, BCH2 is a potent, reversible, and selective MAO-B inhibitor and has been suggested as a candidate for the treatment of neurological disorders.
