Outlining International English language proficiency tests: A survey-based study on its need, purpose and scope in the backdrop of Migration

English as an international language and its proficiency is a gateway for Career, Education and Migration. In order to ensure the same, there are many international English language tests are conducted by different organizations worldwide. Their results and score are considered as a mandatory eligibility criterion for job, education and migration by different organizations and institutions. All these tests are primarily testing the ability of a candidate in the four skills of English Language. This article refers various international English language proficiency tests, its features, question and scoring pattern. The commonly used tests are IELTS, TOEFL, Duolingo English Test, OET, CPE (C2 Proficiency), CAE (C1 Advanced), PTE (Pearson Test of English Academic), TOEIC, iTEP, CELPIP, CAEL, MTELP. It also describes how these tests are differ each other in purpose and patten. The researcher conducted a short survey among UG freshers to analyze their awareness and confidence in English language proficiency tests. The results show that many of the UG learners wish to migrate to foreign countries for higher studies but they don’t have enough awareness regarding the proficiency tests. One of the predominant problems for many non-native speakers of English to secure a good job and failed to be recognized and rewarded in accordance with their skill, is the inefficiency to use English language. Therefore, coaching centers for these tests and its rigorous preparation is a lucrative business in non-European countries especially in a scenario where migration is encouraged. Often, the lack of awareness about these tests and its purpose will mislead the test takers. It is also important to choose the right test as per the field and purpose as the scores of the test

A Performance Assessment on Various Data mining Tool Using Support Vector Machine

Data mining is essentially the discovery of valuable information and patterns from huge chunks of available data. Two indispensable techniques of data mining are clustering and classification, where the latter employs a set of pre-classified examples to develop a model that can classify the population of records at large, and the former divides the data into groups of similar objects. In this paper we have proposed a new method for data classification by integrating two data mining techniques, viz. clustering and classification. Then a comparative study has been carried out between the simple classification and new proposed integrated clustering-classification technique. Four popular data mining tools were used for both the techniques by using six different classifiers and one clustered for all sets. It was found that across all the tools used, the integrated clustering-classification technique was better than the simple classification technique. This result was consistent for all the six classifiers used. For both of the techniques, the best classifier was found to be SVM. From the four tools used, KNIME found to be the best in terms of flexibility of algorithm. All comparisons were drawn by comparing the percentage accuracy of each classifier used

Prolonged jaundice in an apparently healthy baby: A review

Jaundice persisting beyond 14 days of life is a commonly encountered problem in the neonatal follow-up clinic. Although by far the most common underlying etiology is breast milk jaundice, clinician should not miss out an important surgical condition the extrahepatic biliary atresia (an incidence of about 1 in 10000 live births) whose outcome without a surgical intervention before 8 weeks is dismal. Eminently treatable entities such as hypothyroidism and urinary tract infection also can present as prolonged jaundice. This article will synthesize the available literature on this topic and present an algorithm for evaluation of neonates presenting with prolonged jaundice useful to pediatricians in outpatient practice

3-(7,8,13,14-Tetra­hydrodi­benzo­[a,i]phen­an­thridin-5-yl)benzene-1,2-diol

In the title compound, C27H21NO2, the half-chair conformation of the alicyclic rings gives rise to a slightly folded structure of the central tricyclic tetra­hydrophenanthridine unit. Tandem intra­molecular O—H⋯N and O—H⋯O hydrogen bonds give rise to adjacent S(6) and S(5) rings, respectively, which dictate the conformation of the 5-aryl substituent. In the crystal structure, an inter­molecular C—H⋯O contact generates chains parallel to [101]. Short O—H⋯π and C—H⋯π contacts are also observed

(3E,5E)-1-Benzyl-3,5-bis­(2-fluoro­benzyl­idene)piperidin-4-one

The inversion-related mol­ecules of the title compound, C26H21F2NO, associate into closed dimeric subunits via co-operative C—H⋯π inter­actions. Two non-classical C—H⋯O and one C—H⋯N intra­molecular hydrogen bonds are also found in the crystal structure. The piperidin-4-one ring adopts a sofa conforamtion with the 1-benzyl group in the equatorial position, and the equiplanar fluoro­phenyl substituents in the 3- and 5-positions stretched out on either side. The 1-benzyl group is disposed towards the substituent in the 6th position of the piperidin-4-one ring. The 3,5-diene units possess E configurations

Influence of Nickel Coating on Flexural and Dynamic Behaviour of Aluminium

AbstractElectroless deposition is an autocatalytic chemical technique to deposit a layer of metal on a thin work piece in the presence of a reducing agent. In this work the changing structure of nickel deposits on aluminum and its alloys at the early stage of electroless nickel deposition using sodium hypophosphite ion as a reducing agent has been studied. The influences of nickel coating on flexural and dynamic behaviour of aluminium are investigated using experimental and numerical methods. Three-point bending tests are performed on coated & uncoated aluminium. The natural frequency of coated specimen and uncoated specimen has been studied. The nickel coating increases the natural frequency in aluminium. Experimental results are compared with finite element Analysis

Comparative evaluation of sulphur sources on growth, yield and quality of garlic (Allium sativum L.)

Sulphur is a prime nutrient in Allium crops. Garlic fertilization with ammonium-based sulphur fertilizers in low pH soils is being practiced by farmers that culminate the soil acidity, which has an adverse effect on plant growth. Hence a field experiment was conducted at Horticultural Research Station, Woodhouse farm, Ooty, the Nilgris in 2021 to evaluate the appropriate sulphur sources and their levels for garlic at acidic hilly soil using four sulphur sources viz., potassium sulphate, magnesium sulphate, zinc sulphate and ammonium phosphate sulphate and three levels viz., 0, 40, 60 kg ha-1. Garlic variety Ooty 2 was used as test crop. The results revealed that application of magnesium sulphate @ 60 kg ha-1 produced the highest plant height, leaf numbers, clove numbers bulb-1, neck thickness, polar diameter, equatorial diameter, the weight of 10 cloves, fresh weight, dry weight and bulb yield (16.78 t ha-1) of garlic. Quality parameters viz., total soluble solids, ascorbic acid and total phenols of garlic bulbs were improved by the application of potassium sulphate @ 60 kg ha-1. Sulphur source of Magnesium sulphate had a minimal effect of rendering acidity to soil measured in terms of pH (4.74) and exchangeable acidity (0.22 meq 100 g-1). Hence, the promising source for acidic hilly soil and garlic crop was found to be magnesium sulphate @ 60 kg ha-1 followed by potassium sulphate @ 60 kg ha-1. This particular investigation focuses not only on yield improvement but also on maintaining soil quality of the area

In the title compound C32H31NO3, the all­yloxy groups on either side of the piperidin-4-one ring are conformationally disordered. The contribution of major and minor components of the allyloxy group at the 3rd position of the ring are 0.576 (4) and 0.424 (4), respectively, and those at the 5th position are 0.885 (3) and 0.115 (3), respectively. The six-membered piperidin-4-one ring adopts a sofa conformation with the benzyl group occupying an equatorial position and the olefinic double bonds possessing an E configuration. Flanking phenyl substituents are stretched out on either side of the six-membered ring. π–π inter­actions with a centroid–centroid distance of 3.885 (1) Å give rise to mol­ecular dimers and short C—H⋯π contacts lead to chains along the c axis

Genomics-Integrated Breeding for Carotenoids and Folates in Staple Cereal Grains to Reduce Malnutrition

Globally, two billion people suffer from micronutrient deficiencies. Cereal grains provide more than 50% of the daily requirement of calories in human diets, but they often fail to provide adequate essential minerals and vitamins. Cereal crop production in developing countries achieved remarkable yield gains through the efforts of the Green Revolution (117% in rice, 30% in wheat, 530% in maize, and 188% in pearl millet). However, modern varieties are often deficient in essential micronutrients compared to traditional varieties and land races. Breeding for nutritional quality in staple cereals is a challenging task; however, biofortification initiatives combined with genomic tools increase the feasibility. Current biofortification breeding activities include improving rice (for zinc), wheat (for zinc), maize (for provitamin A), and pearl millet (for iron and zinc). Biofortification is a sustainable approach to enrich staple cereals with provitamin A, carotenoids, and folates. Significant genetic variation has been found for provitamin A (96–850 mg and 12–1780 mg in 100 g in wheat and maize, respectively), carotenoids (558–6730 mg in maize), and folates in rice (11–51 mg) and wheat (32.3–89.1 mg) in 100 g. This indicates the prospects for biofortification breeding. Several QTLs associated with carotenoids and folates have been identified in major cereals, and the most promising of these are presented here. Breeding for essential nutrition should be a core objective of next-generation crop breeding. This review synthesizes the available literature on folates, provitamin A, and carotenoids in rice, wheat, maize, and pearl millet, including genetic variation, trait discovery, QTL identification, gene introgressions, and the strategy of genomics-assisted biofortification for these traits. Recent evidence shows that genomics-assisted breeding for grain nutrition in rice, wheat, maize, and pearl millet crops have good potential to aid in the alleviation of micronutrient malnutrition in many developing countries
