Role of Machine Learning in Sentiment Analysis- A Review

Amongst the most basic activities in natural language processing is to know and understand low-dimensional vector presentations of words from a huge dataset. The organizational forms embedding system trains word vectors primarily from grammatical rules and semantic relations from the sense, disregarding sentiment polarity in the sentences. While some methods prototype sentiment data from feedback, they ignore specific language in various contexts. If the responded vector is easily adapted to the evaluation of sentiment classification task when the sentimentality keeps changing, the sentiment classification performance will suffer immensely. The methodologies was using to categories sentiment classification are discussed in this paper

Functional and radiological comparison of transforaminal lumbar interbody fusion method with interbody fusion device versus stand-alone bone graft in lumbar canal stenosis or degenerative lumbar instability

Background: Spinal stability is the vertebral ability to maintain their relationship and limit their relative displacements during physiologic postures and loads.Methods: Hospital based prospective randomized comparative study design between 2 groups included patients of both sex attending SMS hospital Jaipur, from April 2018 to June 2019 or till sample size was achieved, with due permission from institutional ethical committee and review board and after taking written informed consent from patients.Results: Inter group comparison of VAS score showed same results in both groups which showed statistically non-significant results. VAS score showed significantly reduction in both group A and B till the study period. Inter group comparison of ODI score showed same results in both groups which showed statistically non-significant results. ODI score showed significantly reduction in both group A and B till the study period. Inter group comparison of fusion rate score showed same results in both groups which showed statistically non-significant results. Fusion rate score showed significantly increased in both group A and B till the study period and at the 12 month it was 100% fusion rate.Conclusions: In the current series, the TLIF procedure with local bone graft alone improved anterior vertebral translation, disc height, and lumbar lordosis. A proper surgical technique with adequate discectomy and facetectomy would contribute greatly to the improvement of the radiological parameters; however, this improvement was not maintained at the latest follow up.

On the solutions of fractional reaction-diffusion equations

In this paper, we obtain the solution of a fractional reaction-diffusion equation associated with the generalized Riemann-Liouville fractional derivative as the time derivative and Riesz-Feller fractional derivative as the space-derivative. The results are derived by the application of the Laplace and Fourier transforms in compact and elegant form in terms of Mittag-Leffler function and H-function. The results obtained here are of general nature and include the results investigated earlier by many authors

An educational intervention’s effect on healthcare professionals’ attitudes towards pharmacovigilance

BackgroundPharmacovigilance concerns the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. Consumer pharmacovigilance is the involvement of consumers in adverse drug reaction (ADR) reporting. Assessing healthcare professionals’ (HCPs) knowledge of and attitude towards pharmacovigilance and consumer pharmacovigilance is integral to strengthening adverse drug reaction reporting systems. AimsTo study knowledge of and attitude towards pharmacovigilance and consumer pharmacovigilance among HCPs from KIST Medical College, Lalitpur, Nepal, and to plan an appropriate educational intervention to address deficiencies noted.Methods The study was conducted from February 2013 to December 2013 at KIST Medical College using a self-administered, pretested, structured questionnaire. The maximum possible scores for knowledge, attitude, and total were 100, 95, and 195, respectively. Baseline knowledge and attitude were studied. Two months after the questionnaire, an intervention that used a combination of methods about pharmacovigilance and consumer pharmacovigilance was undertaken. Knowledge and attitudes were studied immediately after the intervention. Scores before and after the intervention were compared using Wilcoxon signed-rank test.Results A total of 105 HCPs participated. The median (interquartile range) knowledge, attitude, and total scores before the intervention were 56 (7), 72 (9), and 127 (16), respectively. After the intervention the scores increased significantly to 72 (8), 75 (11.5), and 146 (16.5) (

A Determination of gas outflow fluxes and study its transport mechanism by the application of flux chamber technique from the two landfill sites of semiarid region of Rajasthan

The investigation was executed to assess outflows of CO2 and CH4 gases from the two landfill sites of Udaipur using commonly applied multiple methodologies for the field to ascertain the accuracy and reliability of data imparted by each of these. To examine the potentiality of each gas discharge quantum for prospective energy that could be used further in waste-to-energy (WtE) projects, a field study was conducted for a period from January 2018 to December 2019 with the division of these landfill sites into segments. The gas samples were recorded onsite at demarked points in each segment by inverting the open portion of the Static Flux Chambers (SFCs) on the landfill surface to stop the ingress of air. This SFC was separately connected with the CO2 and CH4 gas analysers to record their onsite concentrations. The recorded data was further analysed to observe the annual quantitative spatial and temporal variations in the fluxes of these two gases. The mean CO2 and CH4 fluxes of Balicha Landfill Site (BLS) ranged between 932-1876μg/m2/hr and 359-1173μg/m2/hr, respectively. On the other hand the mean CH4 and CO2 fluxes of Titardi Landfill Site (TLS) ranged between 672 - 1483 μg/m2/hr and 157 - 958 μg/m2/hr, respectively. These fluxes emitted from BLS and TLS generated the carbon footprint (CF) of 180000 and 78000 ton of CO2 equivalent (tCO2 eq.) sequentially. In order to ensure the significance of the method used and to get best energy output for the WtE project the obtained gas flux data of both the sites was analysed and compared. This studied data would provide a guideline for the concerned authorities to plan & execute gas extraction operations at these two sites

COVID-19 Implicated Ban on Diwali Fireworks: A Case Study on the Air Quality of Rajasthan, India

Diwali is a five-day festival celebrated every year with lamp illumination and bursting of firecrackers in India. Considering the present situation of the COVID-19 pandemic, the Rajasthan government im- posed a ban on firecrackers during the five-day festivities in the year 2020 to tackle air pollution caused by the emission of harmful pollutant gases from their burning. This paper has assessed the concentration of PM10, PM2.5, CO and SO2 pollutants, which are released from fireworks in large amounts in the environment during the Diwali festival. Seven air quality monitoring stations viz. Ajmer, Alwar, Jaipur, Jodhpur, Kota, Pali and Udaipur in Rajasthan state were selected to examine the effect of a ban on the use of firecrackers during the Diwali festival. The analysis was done by comparing the mean concentrations of baseline data and Diwali day data of 2019 and 2020. The results depict that the firecracker ban helped in declining the concentrations of all the air pollutants (PM2.5, PM10, CO and SO2) taken into consid- eration, which significantly improved the ambient air quality of Rajasthan during the Diwali festival, and it is suggested that such regulations should be implemented from time to time to improve the quality of air and human health effectively

Chloroxylon swietenia DC. (Family: Rutaceae) is an important traditional medicinal plant used in the treatment of various ailments like fungal infection of skin, rheumatism, common cold, cough, ophthalmic infection and cataract, wounds and as an astringent. However, detailed scientific information is not available to identify the plant material, in order to ascertain its quality and purity. In this paper, we report the pharmacognostic evaluation of the bark for the purpose of its identification and differentiation from related species. The macroscopy, microscopy, physicochemical parameters such as moisture content, ash values, extractive values, fluorescence analysis and preliminary phytochemical analysis of the bark were investigated. Transverse section of the bark shows presence of cork, cortex, medullary rays, and stone cells. Presence of cork, stone cells, phloem fibres and parenchyma cells which were also observed in the powdered sample of the bark. The result of preliminary phytochemical screening indicated presence of alkaloids, steroids, carbohydrates, proteins, phenolic compounds, tannins flavonoids and triterpenoids. The present study will be useful for its identification prior to carrying out further research work. The findings of this study will facilitate pharmacognostic standardization of the plant material and aid in the preparation of a herbal monograph for the species

Studies on antidiabetic activity of Acacia ferruginea DC. stem bark

The methanol extract of Acacia ferruginea (Family- Mimosaceae) was studied for possible antidiabetic activity on normoglycaemic, OGTT and alloxan induced diabetic rats at doses of 100, 200, and 400 mg/kg, p.o. The acute toxicity studies were carried out on Swiss albino mice to determine the LD50 values. The experiments were performed as per OECD guidelines. The results of the normoglycaemic, OGTT and hyperglycaemic studies revealed that the extract exhibited reduction in blood glucose concentration in a dose dependant manner as compared to the standard drug metformin (250 mg/kg, p.o.). The acute toxicity studies revealed no signs of mortality in animals treated with a single dose of 2000 mg/kg body weight. Preliminary phytochemical studies of the methanol extract revealed presence of alkaloids, steroids, triterpenoids, saponins, flavonoids, tannins and phenolic compounds, carbohydrates, gums and mucilages, proteins and amino acids. The present study justifies the use of the plant for treating diabetes as suggested in folklore remedies
