A Posteriori Error Estimates for Nonconforming Approximations of Evolutionary Convection-Diffusion Problems

We derive computable upper bounds for the difference between an exact solution of the evolutionary convection-diffusion problem and an approximation of this solution. The estimates are obtained by certain transformations of the integral identity that defines the generalized solution. These estimates depend on neither special properties of the exact solution nor its approximation, and involve only global constants coming from embedding inequalities. The estimates are first derived for functions in the corresponding energy space, and then possible extensions to classes of piecewise continuous approximations are discussed.Comment: 10 page

Bio-efficacy of tank mixed herbicides for control of complex weed flora in soybean (Glycine max L. Merril)

A field experiment was conducted at ZARS, Jhabua (M.P.) during kharif 2014 to find out most suitable and efficient method of weed control in soybean. The experiment consisted of nine treatments laid out in randomized block design with three replications. All the weed management practices led to significant reduction in density and dry matter of weeds as compared to weedy check. Two hand weeding (20 & 40 DAS) recorded lowest weed density (4.9/ m2), weed dry matter (22.35 g/m2) with highest weed control efficiency of 59.67% and found at par with the application of Chlorimuron Ethyl @ 9gm /ha + Quizalofop-p-ethyl @ 50 g /ha (density 5.48/ m2, dry matter 26.62 g/m2 and WCE of 51.97%) and Imazethapyr @ 35 g /ha + Imazamox @ 35 g/ha (density 6.13/ m2, dry matter 26.00 g/m2 and WCE of 53.08%). Maximum yield of 1782 kg/ha was recorded in two hand weeding (20 & 40 DAS) closely followed by Chlorimuron Ethyl @ 9gm /ha + Quizalofop-p-ethyl @ 50 g /ha (1723 kg/ha) and Imazethapyr @ 35 g / ha + Imazamox @ 35 g/ha (1697 kg/ha). Reduction in soybean yield in weedy check to be recorded is 38.78 per cent when compared to weed free and 36.68 per cent in comparison to Chlorimuron Ethyl @ 9gm /ha + Quizalofopp-ethyl @ 50 g /ha. However, highest Benefit to Cost ratio is recorded in Chlorimuron Ethyl +Quizalofop-p-ethyl (3.26) closely followed by Imazethapyr + Imazamox (3.22) and Weed free (3.21)

Higher yields and profits from new crop rotations permitting integration of mediculture with agriculture in the Indo-Gangetic plains

The results of a survey conducted in 100 villages of 7 districts located in Uttar Pradesh in the central Indo-Gangetic plains on the land cropping pattern and profits to the farmers per unit land and area are presented. It is shown that sugarcane is cultivated in about 19.5% of the land. Rice remains the principal kharif crop in the area, occupying about 76% of land. Conventional rice-wheat/Brassica/legume, rice-potato and rice-mint rotations benefitted farmers to the extent of roughly Rs 30,000 ha−1 year−1. Introduction of new rotations based upon newly available short duration Kosi variety of mint is permitting practice of rice-wheat/Brassica/legume-mint and rice-potato-mint rotations, bringing a profit of approximately Rs 61,000 ha−1 year−1 to the farmers of the area. Future prospects of integration of short duration medicinal and aromatic crops (mediculture) between food grain crops (agriculture) like the above, for the development of agriculture, industry and employment are discussed

Development of ANFIS Control System for Seismic Response Reduction using Multi-Objective Genetic Algorithm

Adaptive neuro fuzzy inference system (ANFIS) and Genetic algorithm (GA) was proposed in this study to reduce dynamic responses of a seismically excited building. A multi-objective genetic algorithm (MOGA) was used to optimize the ANFIS+GA controller. Two MR dampers were used as multiple control devices and a scaled five-story building model was selected as an example structure. A fuzzy control algorithm was compared with the proposed ANFIS and ANFIS+GA controller. Adaptive neuro-fuzzy inference system (ANFIS) and Ganetic algorithm with several outputs was proposed. In case study, after numerical simulation, it has been verified that the ANFIS control algorithm can present better control performance compared to the fuzzy control algorithm in reducing both displacement and acceleration responses

Knowledge and awareness of basic life support among MBBS students in tertiary care hospital in Uttar Pradesh

Background: Every medical student in India have to undergo a compulsory rotatory internship for completion of their course where they encounter various medical emergencies and apply their medical knowledge. An early encounter to a basic life support course and training will increase the efficacy of cardiopulmonary resuscitation and thus the outcome of the patient. This study was designed to test knowledge of MBBS students in a tertiary care hospital.Methods: This observational study was conducted in a tertiary care hospital in Uttar Pradesh and used a preformed validated questionnaire to test awareness and knowledge of basic life support and cardiopulmonary resuscitation in a sample of 500 MBBS students. Descriptive analysis was performed on the questionnaire responses. All data obtained from the questionnaire was evaluated and statistically analysed using software IBM SPSS Statistics software version 24 (IBM Corp., Armonk, NY, USA) for MS windows.Results: With a response rate of 47% among 500 MBBS students, the mean score obtained was 2.34±1.066 out of a maximum score of five. A maximum score of 2.804±1.055 obtained by 5th-year students. Surprisingly, first-year students achieved an average score of 2.66±0.97, which was higher than that of 2nd, 3rd, and 4th year students. 87% of students were like-minded to participate in the cardiopulmonary resuscitation (CPR) awareness program. Only 45% of students correctly answered the order of CPR as C-A-B (chest compression-airway-breathing).Conclusions: The study showed that though the awareness and importance of basic life support (BLS) are high among the medical students, the accurate knowledge required in performing BLS is inadequate. This study also showed that the National medical commission has taken a positive step in the incorporation of BLS in the curriculum

Character association and path analysis for yield components in turmeric (Curcuma longa L.)

Correlation and path analys is of 11 characters of turmeric (Curcuma longa) were carried out using 22 genotypes at Raigarh (Chhattisgarh). Plant height, leaf length, thickness of primary and secondary rhizomes and number of secondary rhizomes revealed significant positive associations with rhizome yield. Path analysis showed positive direct effect of plant height, leaf length and thickness of primary and secondary rhizomes on rhizome yield. These traits may be given due e,,'phasis while making selections for improvement in rhizome yield of turmeric. &nbsp

Nutritional and Phytochemical Traits of Apricots (Prunus Armeniaca L.) for Application in Nutraceutical and Health Industry

Apricot (Prunus armeniaca L.) is a nutritious fruit, rich in bioactive compounds, known for their health benefits. The present study attempts to evaluate nutritional (sugars, organic acids, minerals) and nutraceutical traits (total phenolics, flavonoids, carotenoids, antioxidant activity) of six commercial apricot genotypes grown in India. Antioxidant activity was determined using three in-vitro assays, namely CUPRAC (cupric reducing antioxidant capacity), FRAP (ferric reducing antioxidant power) and DPPH (1,1-diphenyl-2-picryl-hydrazyl). Significant (p < 0.05) differences were observed in the genotypes concerning nutritional and nutraceutical traits. Sucrose accounted for more than 60% of total sugars in most genotypes, followed by glucose and fructose. Citric acid accounted for more than 50% of the total organic acids present, followed by malic and succinic acids. Apricot is a good source of potassium (1430.07 to 2202.69 mg/100 g dwb) and iron (2.69 to 6.97 mg/100 g dwb) owing to its mineral composition. Total carotenoids content ranged from 0.44 to 3.55 mg/100 g, with β-carotene accounting for 33-84% of the total content. The results strongly suggest that genotypes 'CITH-A-1' and 'CITH-A-2', which have high dry matter and carotenoids content, are well suited for drying. 'Roxana' and 'CITH-A-3' are great for fresh consumption, while 'Shakarpara' and 'Gold Cot' are excellent for juice processing

Functional characterization of a panel of high-grade serous ovarian cancer cell lines as representative experimental models of the disease.

Genomic analysis of ovarian cancer cell lines has revealed a panel that best represents the most common ovarian cancer subtype, high-grade serous ovarian cancer (HGSOC). However, these HGSOC-like cell lines have not been extensively applied by ovarian cancer researchers to date, and the most commonly used cell lines in the ovarian cancer field do not genetically resemble the major clinical type of the disease. For the HGSOC-like lines to serve as suitable models, they need to be characterized for common functional assays. To achieve that objective, we systematically studied a panel of HGSOC cells CAOV3, COV362, Kuramochi, OVCAR4, OVCAR5, OVCAR8, OVSAHO and SNU119 for migration, invasion, proliferation, clonogenicity, EMT phenotype and cisplatin resistance. They exhibited a range of efficacies and OVCAR5, OVCAR8 and Kuramochi were the most aggressive. SNU119 and OVSAHO cells demonstrated the lowest functional activities. Wide differences in expression of EMT markers were observed between cell lines. SNU119 were the most epithelial and OVCAR8 had the most mesenchymal phenotype. COV362 was the most resistant to cisplatin while CAOV3 was the most sensitive. Taken together, our systematic characterization represents a valuable resource to help guide the application of HGSOC cells by the cancer research community
