Iodine Deficiency in Goats

Iodine deficiency is a common problem among humans and livestock throughout the world. Prevalence is very high in goats due to less access to soils and browsing habits of goats. It is primarily due to deficiency of iodine in soil, feed, fodder, and water or secondarily due to the presence of goitrogens in diet of animals. Clinical deficiency is characterized by cardinal signs of goiter, whereas subclinical deficiency is difficult to diagnose because clinical signs are not evident. Clinical signs are more prevalent in kids as compared to adults. Diagnosis is on the basis of clinical sign of goiter and estimation of thyroid hormones, the plasma organic iodine level. Milk and urine iodine levels are good indicators of iodine deficiency. Deficiency can be prevented by daily supplementation of iodine and avoiding diets high in goitrogens

A LIGHT WEIGHT SOLUTION FOR DETECTING DE-AUTHENTICATION ATTACK

Nowadays Wireless local area networks (WLANs) are growing very rapidly. Due to the popularity of 802.11 networks, possibilities of various attacks to the wireless network have also increased. In this paper, a special type of attack De-Authentication/disassociation attack has been investigated. In a normal scenario, a wireless client or user sends a de-authentication frame when it wants to terminate the connection. These frames are in plain text and are not encrypted. These are not authenticated by the access point. Attackers take advantage of this, and spoof these packets and disable the communication between the connected client and access point. In this paper, an algorithm based on radio-tap header information is suggested to identify whether there is a De-Authentication attack on the client or not

Journal of Documentation: A Bibliometrics Analysis (2005-2018)

The purpose of this article was to explore the pattern of publications, using bibliometric analysis, of Journal of Documentation for the period of 2005 to 2018. The results of the study shows that a total of 687 articles were published in the 14 years period from 2005 to 2018, with 71 (10.3%) articles being published the highest total in the year 2018. The study confirmed that the maximum number of articles i.e. 304 (43.9%), were published by single authors, out of which, a large number were on research articles. Out of total number of articles published 228 (33.1%) were 16-20 pages in length. Volume number 74 in 2018 had the highest number of citations with a total of 91 (13.6%). In addition, the study confirmed that the highest number of articles were research articles with a total of 493 (71.7), while others were case studies, conceptual studies, literature reviews, viewpoints and technical papers and short communications, etc

PERCEPTIONS OF LIBRARY PROFESSIONALS TOWARDS WEBINARS IN HARYANA (INDIA)

Webinars are proving a boon for all academic fraternity in the present scenario of COVID-19 pandemic when almost all learning and education centers are in state of lockdown not only in India but in the world. The present study explores the perceptions of library professionals of Haryana which is one of northern state of India. The data has collected from the professionals via Google questionnaire. Results indicates that Whats App was the most popular app for promoting webinars among library professionals, Zoom platform was widely preferred, mobile devices were highly used, free webinars were attended by majority of professionals, the main intention to attend webinars was to gain knowledge on burning topics, more than eighty percent were satisfied with webinars and found them as per their expectations, and 35.9 percent participants were disagreed or strongly disagreed on the statement ‘Webinars can replace the class room teaching’. The study may generalize the utility and continuity of webinars for future perspectives even when the COVID period is over

Linkage mapping of QTLs for grain minerals (iron and zinc) and physio-morphological traits for development of mineral rich rice (Oryza sativa L.)

69-80In the present investigation, experiments were conducted to evaluate F3 and F4 populations derived from cross between PAU201 (high-yield) and Palman 579 (iron-rich) indica rice varieties for various physio-morphological traits and minerals (iron and zinc) content. Phenotypic correlation analysis showed no correlation between grain iron and zinc content in F3 and F4 population (s). A DNA fingerprint database of 33 PAU201 × Palman 579 derived F4 plants was prepared using 61 polymorphic SSR markers distributed on the entire genome of rice. The results of NTSYS-pc UPGMA tree cluster analysis and two and three dimensional principal component analysis (PCA) scaling showed scattering of the F4 population between the two distinct parent genotypes; but more inclined towards Palman 579. The SSR data was used to identify quantitative trait loci (QTL) for grain mineral content and physio-morphological traits. A total of 128 alleles and three new recombinant alleles were identified in F4 plants population. Composite interval mapping (CIM) analysis by WinQTL cartographer 2.5 revealed a total of six QTLs for mineral content (five for iron and one for zinc) in rice grains on chromosome 5, 6, 7, 9 and sixteen QTLs for various physio-morphological traits on chromosomes 2, 5, 7, 8, 9, 10 and 12. Linkage mapping of QTLs of minerals (iron and zinc) can greatly enhance the efficacy of breeding programs to improve mineral density in rice. The QTLs for minerals identified can successfully employed to improve the target traits through marker assisted selection

A quick method for surveillance of 59 pesticide residues in fruits and vegetables using rapid three-dimensional gas chromatography (GC/MSD/µ-ECD/FPD) and LC/MS-MS

This article describes a simple, quick and inexpensive method for determination of pesticides in fruits and vegetables. The method, known as the quick, easy, cheap, effective, rugged and safe (QuEChERS) method for pesticide residues, involves the extraction and simultaneous liquid-liquid partitioning formed by adding anhydrous magnesium sulfate (MgSO4) plus sodium acetate (NaAc) followed by a simple cleanup step known as dispersive solid-phase extraction (dSPE). The extracts were analyzed by three-dimensional gas chromatography GC/MSD/µ-ECD/FPD in trace ion mode and liquid chromatography/tandem mass spectrometry (LC/MS-MS). Method sensitivity, linearity, repeatability and reproducibility, accuracy, matrix effects, and overall uncertainties have been studied for method validation according to the international norm ISO/IEC: 17025:2005 for both techniques. Identification, quantification and reporting with Total and Extracted ion chromatograms, µECD and DFPD were facilitated to a great extent by Deconvolution Reporting Software (DRS) for GC and Mass hunter software for LC. For all compounds LODs were 0.001 to 0.01 mg/kg and LOQs were 0.005 to 0.020 mg/kg. Correlation coefficients of the calibration curves were >0.991.To validate the effects of matrices, repeatability, reproducibility, recovery and overall uncertainty were calculated for twenty-four matrices at 0.020, 0.050 and 0.500 mg/kg. Recovery ranged between 75-107 % with RSD <17 % for repeatability and intermediate precision and UM of ± 13-22 %
