A book recommendation system based on named entities

Recommendation systems are extensively used for suggesting new items to users and play an important role in the discovery of relevant new items, be it books, movies or music. An effective recommendation system should provide heterogeneous results and should not be biased towards only the most popular items. Books are particularly well-suited to content-based filtering as they are now widely available in digital formats which can allow various text mining approaches to dig out content related information. This paper presents a framework to develop a content-based recommendation system for books which can further be integrated with a collaborative filtering model. The proposed content-based recommender will use the Named Entities as the basic criteria to rank books and give recommendations

Variable structure control for an isolated boost converter used in fuel cell applications

In recent years fuel cells have become prominent as an alternative source of energy to meet the society’s energy requirements. A control strategy derived from variable structure theory known as Sliding Mode Control (SMC) was proposed for an Isolated Boost topology which was mostly used in fuel cell systems. Converter operation and its detailed mathematical modelling are also presented. Then the converter with the control strategy suggested is simulated in MATLAB/SIMULINK and compared with other controllers. The results show that transient response of the converter is very fast and steady state error is reduced throughout the load change period with proposed control topology

VECTOR CONTROL SCHEME FOR INDUCTION MOTOR WITH DIFFERENT CONTROLLERS FOR NEGLECTING THE END EFFECTS IN HEV APPLICATIONS

This paper develops the application of a different control strategy to the vector control of the voltage-fed induction motor. The proposed model decomposes the control task into three loops, namely, the speed loop, the d-axis flux loop and the q -axis flux loop. Then, tracking of speed with different controllers is designed for each loop. Proportional- Integral update laws are used to adjust the control parameters, which increases the tracking performance (Z-N Method) .Simulations are obtained shows good robustness against parameter variations, high tracking performance and simplicity of implementation

SOSIALISASI EDUKASI BAHAYA TOXOPLASMOSIS TERHADAP KELOMPOK PEMUDA USIA PRODUKTIF DI KOTA KUPANG

Toxoplasmosis is a disease of vertebrate animals and it is capable of being transmitted to humans (zoonosis). Toxoplasmosis is caused by the protozoan parasite Toxoplama gondii. Cats are the definitive host of T. gondii where this parasite will enter the cat's body through what it eats such as rats, raw meat, or water that is contaminated with oocysts of the T. gondii parasite. This condition is generally experienced by stray cats or domesticated cats which are often given raw meat. The purpose of this activity is to increase public understanding of the dangers of toxoplasmosis and how to prevent and anticipate the spread of toxoplasmosis in Kupang City. The method used in this community education was through presentation and discussions about the danger of toxoplasmosis. To measure the level of understanding of the participants about the dangers of toxoplasma, a questionnaire is given at the beginning and at the end of the activity. A total of 38 participants from the productive youth groups in Kupang City were involved in this activity.  The result of this activity shows that the public is increasingly educated about toxoplasmosis and how it is transmitted

The 20-minute whole blood clotting test (20WBCT) for snakebite coagulopathy—A systematic review and meta-analysis of diagnostic test accuracy

Background The 20-minute whole blood clotting test (20WBCT) has been used to detect coagulopathy following snakebite for almost 50 years. A systematic review and meta-analysis of the 20WBCT was conducted to evaluate the accuracy of the 20WBCT to detect coagulopathy, indicative of systemic envenoming. Methods and findings Databases were searched from inception up to 09/12/2020 to identify studies that compared the 20WBCT and INR/fibrinogen on five or more subjects. Data was extracted from full-text articles by two reviewers using a predetermined form. Authors of 29 studies that lacked sufficient details in the manuscript were contacted and included if data meeting the inclusion criteria were provided. Included studies were evaluated for bias using a tailored QUADAS-2 checklist. The study protocol was prospectively registered on PROSPERO database (CRD42020168953). The searches identified 3,599 studies, 15 met the inclusion criteria and 12 were included in the meta-analysis. Data was reported from 6 countries and included a total of 2,270 patients. The aggregate weighted sensitivity of the 20WBCT at detecting INR >1.4 was 0.84 (CI 0.61 to 0.94), the specificity was 0.91 (0.76 to 0.97) and the SROC AUC was 0.94 (CI 0.91 to 0.96). The aggregate weighted sensitivity of the 20WBCT at detecting fibrinogen <100 mg/dL was 0.72 (CI 0.58 to 0.83), the specificity was 0.94 (CI 0.88 to 0.98) and the SROC AUC was 0.93 (0.91 to 0.95). Both analyses that used INR and fibrinogen as the reference test displayed considerable heterogeneity. Conclusions In the absence of laboratory clotting assays, the 20WBCT remains a highly specific and fairly sensitive bedside test at detecting coagulopathy following snakebite. However, clinicians should be aware of the importance of operator training, standardized equipment and the lower sensitivity of the 20WBCT at detecting mild coagulopathy and resolution of coagulopathy following antivenom

Performance of broilers on sorghum-based diets

The effect of replacing maize with sorghum grain on the performance of broilers was studied. Grain from 4 improved Sorghum bicolor cultivars (CSH 16, CSV 15, PSV 16 and S 35) and one traditional yellow variety were used to replace maize (control diet) in the starter (1-4 weeks) and finisher rations (5-6 weeks) of broilers by 50, 75 and 100% levels. All diets were isonitrogenous and isocaloric and were homogeneous for lysine, methionine and cystine levels. One-day-old 512 commercial Cobb female broilers were divided into 64 groups with 16 dietary treatments and 4 replicates per treatment, with 8 birds in each. In a second trial, sorghum replacement was conducted without homogenizing the diets for nitrogen and energy contents. The study lasted for 6 weeks. It was shown that the liveweight gain and feed intake of broilers was statistically similar in sorghum diets at all inclusion levels compared to the control diet. However, the feed conversion efficiency of broilers in the 100% sorghum diet was significantly higher compared to the maize diet (P=0.05). A better feed conversion efficiency was found with the CSV 15, CSH 16, PSV 16 and the local cultivars at 100% inclusion levels. However, the yellow pigmentation of the skin and carcass of the broilers was better in the maize diet compared to the sorghum diets. Cost varied among and within cultivars at different inclusion levels, and was lower in CSV 15, PSV 16, S 35 and local sorghum cultivar-based diets. Cost was also much lower in CSV 15, PSV 16 and local sorghum cultivars at 100% inclusion level compared to maize. Feed cost per kg liveweight gain was lower with CSV 15 (Rs 17.16) and PSV 16 cultivars (Rs 17.62) compared to maize (Rs 18.02). Although pelleting increased feed costs (by Rs 0.25/kg), it also improved broiler production efficiency compared to mash in sorghum diets. Inclusion of Stylosanthes sp. leaf meal at 3% in 100% sorghum-based diets favourably improved the shank and skin colour of the carcass. Carcass yield and abdominal fat of broilers fed sorghum, sorghum + Stylosanthes sp. and maize diets were similar. In conclusion, the inclusion/replacement of sorghum in maize-based diets and pelleting improves the feed conversion ratio and decreases the total feed costs in broiler production

An Orally Bioavailable, Indole-3-glyoxylamide Based Series of Tubulin Polymerization Inhibitors Showing Tumor Growth Inhibition in a Mouse Xenograft Model of Head and Neck Cancer.

A number of indole-3-glyoxylamides have previously been reported as tubulin polymerization inhibitors, although none has yet been successfully developed clinically. We report here a new series of related compounds, modified according to a strategy of reducing aromatic ring count and introducing a greater degree of saturation, which retain potent tubulin polymerization activity but with a distinct SAR from previously documented libraries. A subset of active compounds from the reported series is shown to interact with tubulin at the colchicine binding site, disrupt the cellular microtubule network, and exert a cytotoxic effect against multiple cancer cell lines. Two compounds demonstrated significant tumor growth inhibition in a mouse xenograft model of head and neck cancer, a type of the disease which often proves resistant to chemotherapy, supporting further development of the current series as potential new therapeutics
