Authors: Henjo John Ken
Published: November 2022

Informal studies in Vanuatu indicate that ICT training is promoted but centralized in the urban areas (Port Vila and Luganville), with 70 % of the population coming from rural communities to the urban areas just to access the ICT services. ltuani Vocational Skills Centre (VSC) was established in 2015 to take ICT services and training to rural and remote communities, targeting orphans; girls and women; and people with disabilities. Ituani VCT is the first rural training centre to be registered under the Vanuatu Qualification Authority (VQA) to deliver accredited computer courses through outreach program to target rural schools and communities called ICT to schools and communities. // The major challenges experienced in the outreach programme is the travelling situations, since the provinces and islands are scattered in six different provinces, making it difficult and costly to travel by air, sea, and land due to the bad conditions of the roads and sea. To address these challenges, blended learning approaches was identified as key ensure that the rural communities access the digital skills. Given that the trainers at Ituani did not have relevant skills for blended learning, the TVET Professional Development Online Toolkit for the Pacific was used as a basis for upskilling the staff. The Toolkit was developed through collaboration between the Commonwealth of Learning (COL) and the Pacific Centre for Flexible and Open Learning for Development (PACFOLD) with funding from the New Zealand Ministry of Foreign Affairs & Trade. // Project team was set up, project design workshop was held to develop a detailed project plan, relevant stakeholders were identified and included in project activities. The Toolkit was used to identify training gaps among trainers and develop strategies for upskilling the trainers. Baseline data was collected, five(5)trainers including three(3) males and two (2) females were upskilled with support from COL consultants, the trainers conducted training to fifthy (50) learners including thirty (30) women/girls and twenty (20) men/boys using the knowledge and skills acquired for blended learning, and endline data was gathered, and the Vanuatu VQA recognized skills acquired through the outreach programme.

In India, the yaks are reared by the people residing between 3,000 and 5,000 meters above mean sea level in the states of Jammu-Kashmir, Himachal Pradesh, Uttrakhand, Sikkim, Arunachal Pradesh and West Bengal. Yaks thrive well in these extremely cold regions with hypoxic conditions providing milk, meat, hide, fibre, manure and draught power to the local population. They are able to withstand the fodder scarcity endemic to these regions in the winter months. The total yak population in our country is 0.76 lakhs. Jammu and Kashmir has the maximum population of yak (0.54 lakh), possessing about 71% of the total yak population of the country, followed by Arunachal Pradesh (18.34%) and Sikkim (5.26%). The milk yield per lactation in indigenous yaks is 250–500 kg in a lactation period of 260–300 days. The birth weight of indigenous yaks in males and females is 14.20±0.33 and 13.20±0.34 kg, which increases to 201.23±4.79 and 178.13±3.26 kg, respectively, at 2 years of age. Mainly, four types of Indian yaks have been described namely Arunachali, Ladakhi, Sikkimi and Himachali. Out of these, Arunachali yaks are the first and only recognized breed of Indian yaks. This review summarizes the population trends, attributes of indigenous yaks in general as well of specific types of indigenous yaks available in India.

Published: November 2022

Porcine circovirus type 2 (PCV2) is an emerging viral infection in swine population and results in severe economic loss to piggeries worldwide. The present study was conducted to explore the genetic diversity of PCV2 circulating in swine population of India from 2006–2018. A total of 74 heart, lungs, spleen and lymph nodes collected from different regions in Uttar Pradesh, India were subjected to molecular analysis. For studying genetic diversity, the complete nucleotide and ORF2 sequences of 95 PCV2 including 43 nucleotide sequences from India were used. DNA was extracted from samples and positive samples were subjected to full genome sequencing and phylogenetic analysis was done by maximum likelihood method. Phylogenetic analysis of 40 Indian PCV2 genomes downloaded from GenBank along with three new isolates from the current study based on the complete genome and cap gene together with nucleotide sequences of PCV2 isolates from different countries results in a tree in which Indian isolates clustered in 4 different branches includes PCV2b-1C, PCV2a-2D, PCV 2b-1A/B, PCV 2d-2 recombinant group and two new cluster in which one clustered along with unclassified PCV2 viruses from Indonesia and Croatia. The comparison of ORF2 gene among Indian isolates revealed nucleotide identity ranging from 88.6% to 99.6%, indicating the genetic diversity of PCV2 strains circulating in Indian pig. The present work reports for the first time in India the PCV2-1A/B cluster of 2b genotype and all the Indian isolates available in India from 2006–2018 were used in this analysis.

Published: November 2022

Brucellosis is a neglected zoonotic disease with significant economic and public health consequences to human and animal population in developing countries. The objective of the present study was to determine the serological evidences of brucellosis in cattle reared in two gaushalas of Hisar and Jind districts, Haryana. The serological tests: Rose Bengal Plate Test (RBPT), Serum Agglutination Test (SAT) and Enzyme Linked Immunosorbent Assay (ELISA) were employed for screening the animals for brucellosis. The overall seropositivity by RBPT, SAT and ELISA was 23.46%, 20.67% and 28.49% respectively. The logistic regression modalities concluded higher likelihood of brucellosis with age > 6 years followed by 3–6 year than cows with <3 years. The agreement between tests (RBPT and ELISA, SAT and ELISA and RBPT and SAT) was found to be 0.87 (95% CI: 0.857–0.882), 0.70 (95% CI: 0.684–0.718) and 0.82 (95% CI: 0.809–0.834) respectively by kappa statistic. This study concluded high infection rate in gaushala where animals were kept as closed population with more risks of brucellosis among older milching animals which poses potential public health risk through consumption of unpasteurized milk.

Published: November 2022

The objective of this study was to investigate the prevalence of Contagious caprine pleuropneumonia (CCPP) in small ruminants in Hassan district, Karnataka, India and to evaluate the accuracy of Slide Agglutination Test (SAT) over competitive ELISA (cELISA) diagnostic methods. A total of 227 serum samples from apparently healthy goat and sheep were screened for CCPP antibodies by SAT and cELISA. The study revealed no significant difference in seroprevalence of CCPP with respect to species (Goat vs Sheep), sex (Male vs Female) and farms (Organised vs Unorganized), where as significant difference was noticed in age groups by both SAT and cELISA diagnostic methods. The prevalence of CCPP by SAT and cELISA in sheep were 31.81% and 41.55% and goat 30.14% and 38.35% respectively. Higher seroprevalence rate was observed in older animals of more than five years compared to less than five years age groups. The sensitivity, specificity and accuracy of SAT as compared with cELISA in CCPP diagnosis was 78.41%, 98.56% and 97.75% respectively. The results of this study indicated the endemicity of the CCPP infection in and around Hassan region of Karnataka state and further showed that SAT being economical with good sensitivity and accuracy can be effectively used in the absence of cELISA kits.

Published: November 2022

The present study was designed to determine the relationship between Anti-Müllerian hormone (AMH) and antral follicular population (AFP), milk yield (MY), body weight (BW), body condition score (BCS) and resumption of cyclicity (RC) in postpartum buffaloes. For the present study, 20 buffaloes divided into 2 groups: Group I (n=10): buffaloes resuming cyclicity <30 days of calving; Group II (n=10): anestrous buffaloes >90 days postpartum. Blood sampling was carried out in all buffaloes in both groups at day 30 postpartum (day 0 considered as calving day). BW and BCS were monitored fortnightly and MY was recorded every week during first month of lactation. In this study, we found that none of the parameters (AMH, MY, BW and BCS) differed significantly, though RC differed between the two groups based on cyclicity, monitored using transrectal ultrasonography. In addition, AFP between the two groups (A: 19.7±4.95 vs 15.7±5.08) showed a trend in difference, though non-significant. Correlation study between the parameters, i.e. AMH, AFP, MY, BW, BCS and RC in postpartum buffaloes revealed nonsignificant correlation between AMH with AFP, MY, BW, BCS and RC in postpartum buffaloes. In summary, this study failed to deduce any relationship between AMH with AFP, MY, BW, BCS and RC in postpartum buffaloes.

Published: November 2022

Lower parasitemia often skips the conventional microscopic and serological techniques from detecting latent, cryptic and/or chronic carrier states of bovine tropical theileriosis (BTT). Hence the molecular detection of the parasitic DNA remains a highly authenticated tool. Oligonucleotide primers (TBR F/R) were custom designed and used for PCR amplification of T. annulata. The sensitivity and specificity of PCR was compared with blood microscopy based on kappa value predictions. A total of 8 samples were found positive by blood smear examination whereas PCR detected 12 infections. Blood smear examination was kept as a gold standard for detecting actual number of confirmed positive cases, for being 100% sensitive along with 93.65% specific, respectively, in detecting calf theileriosis. The described PCR-based assay provides a valuable tool to study the epidemiology of BTT in calves and some vital data regarding epidemiology of theileriosis in calves from semi-arid parts of India has been generated. Such a record for screening of calves for theileriosis is missing from Indian context.

Published: November 2022

The study was undertaken to estimate the genetic parameters, direct and correlated responses for the test day and lactation milk yield in Frieswal cattle. Data on 9,955 daily milk yield records of 973 Frieswal cows calved during 2005 to 2014 at Ambala and Meerut dairy farms were utilized. The variance components, heritability estimates, genetic and phenotypic correlations for all the 11 traits were estimated simultaneously by fitting multi-trait animal model using the Wombat program of Meyer (2006) with contemporary groups as fixed effect, the additive genetic random effects, linear and quadratic regressions of covariate age at first calving and linear regression of covariate first lactation length. The expected genetic gain (DG), correlated response (CR) in cumulative 305-day yield and vice versa and the relative efficiency (RE %) of selection based on different test day yields were estimated. The results revealed lower additive genetic variance and heritability estimates for different test days and cumulative 305-day yield. The genetic correlations between the test days up to 225 and cumulative 305-days were higher which indicated the positive relationship between these traits. The higher correlated responses in cumulative 305- day yield estimated through the selection for TD135, TD165 and TD45, in that order indicated that early selection of sires using test day records would be efficient in genetic improvement for lactational milk yield in Frieswal breed of cattle.

Published: November 2022

Bael [Aegle marmelos (L.) Correa ex Roxb., Family Rutaceae] is one of the oldest known fruit tree species native to India. Wide distribution of bael in Indian subcontinent and other parts of the world reflects its adaptation to a range of agro-climatic conditions. In addition to well-known nutritional and traditional medicinal benefits, the bael fruits have considerable processing and industrial values. In order to better utilize and improve the existing genetic resource, there is a need scrutinizing the studies related to genetic diversity, characterization, evaluation and conservation, taxonomy, phenology, floral biology and pollination. In addition, survey of literature for better understanding of various agrotechniques, propagation methods, canopy management, biotic and abiotic stresses and their management is equally important for improving the fruit productivity and quality.Accordingly, this review paper intends to critically examine and systematically arrange the voluminous literature available on aforementioned aspects of bael tree.

Authors: JEET PAWAN , SINGH D K , SARANGI A
Published: November 2022

This study presented a modified concept of assessing groundwater potential and water table level behavior under varying rate of recharge potential for regional scale modeling of Betwa basin using Processing ModFlow for Windows model. Betwa basin of Bundelkhand region which covered the districts of Madhya Pradesh and Utter Pradesh was selected to apply this concept. The model was calibrated and validated using observed water table elevation data for the period 2005â€“2013, which showed agreement between observed and predicted water table elevation. The coefficient of determination (R2) ranged between 0.74â€“0.87 for calibration and 0.63â€“0.87for validation. Scenario analysis represents the water table elevation under three varying groundwater recharge condition in Shahijina, Garrauli, Mohana and Basoda sub-basin of Betwa basin. Results shows that the scenario based on recharge with 60% of surface runoff combined with river bed recharge and natural recharge has maximum influence on groundwater recharge. Groundwater recharge under the scenario varied from 0.33â€“1.61 m above reference level. Recharge from 30% of surface runoff combined with river bed recharge and natural recharge varied from 0.16â€“1.05 m above reference level. The study shall be useful for planning of groundwater development in Betwa basin and to suggest an alternate location for development of soil and water conservation structure. The water table elevation simulation also showed that the recharge levels and the sustainability of groundwater resources cannot be ensured unless water availability in arid to semi-arid region river basin increased.

Published: November 2022

An experiment was conducted during post-rainy seasons of 2012â€“13 and 2013â€“14 at Indian Institute of Millet Research, Rajendranagar, Hyderabad to see the effect of preceding legumes, irrigation and N levels on rabi sorghum (Sorghum bicolor (L.) Moench) productivity and soil quality. Results revealed that the in situ incorporation of Sesbania during kharif significantly increased the grain yield (2511 and 3024 kg/ha) of post-rainy sorghum as compared to kharif fallow (2409 and 2930 kg/ha). Further, irrigation at four critical stages, viz. PI, booting, anthesis and milking had significantly out yielded other irrigation levels. Application of 60 kg N/ha produced grain yield on a par with 90 kg N/ha. Sesbania green manure incorporated plots contained significantly more population of soil microbes (bacteria, fungi and actinomycetes). The available nutrients (NPK) were significantly higher due to the incorporation of Sesbania as compared to the haulms of greengram or stubbles of cowpea.

Published: November 2022

The present study was carried out to minimize postharvest problems of chilling injury during cold storage by the application of anti-chilling compounds, viz. salicylic acid (SA), sodium nitroprusside (SNP) and a nitric oxide donor (NO). For minimizing chilling injury symptoms summer squash (Cucurbita pepo L.) fruits were treated with salicylic acid (1.0â€“1.5 mM) and sodium nitroprusside(1.0â€“1.25 mM) followed by cold storage at 5Â±2ÂºCand 85â€“90% relative humidity. Among the used anti-chilling molecules, salicylic acid @1.0 mM provides the best results for minimizing chilling injury score (0.74) and proline content (333.87 Î¼g/g) during cold storage. Fruits treated with 1.5 mM SA and 1.0 mM SNP showed a 37.42% and 27.42% lower electrolyte leakage as compared to control. In the case of malondialdehyde (MDA) content, 1.0 and 1.5 mM SA dose showed a â‰ˆ39% and â‰ˆ36% lower content than control. Higher fruit firmness (7.07 N) retention was found in 1.0 mM sodium nitroprusside and followed by 1.0 mM salicylic acid (6.96 N) treated fruits. Overall 1.0 mM salicylic acid followed by 1.0 mM sodium nitroprusside proves better for prevention of chilling injury and lower production of malondialdehyde content.

Is the Solution Dilution? Hidden Uncertainty in Gas Chromatography (GC) Methods
Authors: Snow Nicholas H.
Published: November 2022

Used by chemists and nonchemists alike, gas chromatography (GC) is considered mature and among the most widely used instrumental techniques for chemical analysis. Because instruments have become both more sensitive and easier to use, columns have achieved higher resolution and stationary phases have greater selectivity. As a result, gas chromatographs have taken on a “black box” view. With greater sensitivity, resolution, and advanced data handling capabilities, a new set of experimental uncertainties emerge that may not be apparent to most users, especially those who were not formally trained as analytical chemists. In this installment of ”GC Connections,” we examine these uncertainties in typical GC methods, especially as they relate to quantitative analysis. We look at hidden experimental uncertainty, especially in the glassware used for sample preparation. We also comment on injection and detection with an eye toward understanding the sources of the errors. It is important to understand the experimental error and uncertainty are inherent in all analytical techniques; they can be reduced but cannot be eliminated.
Development of a System Suitability Test for Two-Dimensional Liquid Chromatography
Authors: Baghdady Yehia Z.
Published: November 2022

Verifying system performance is important when using chromatographic instrumentation for analyzing both known and unknown samples. Typically, system suitability tests (SSTs) are used to verify performance, which involves running an established method and comparing the results to pre-established acceptance criteria. As two-dimensional liquid chromatography (2D-LC) becomes used more widely and in regulated laboratory environments, development and implementation of SSTs will be critical for successful routine use of the 2D-LC technique.
Quantitative Analysis of PFAS in Milk, Infant Formula, and Related Ingredients Using Liquid Chromatography–Tandem Mass Spectrometry
Authors: Vaclavik Lukas , Schmitz John , Eckert Matthew , Mastovska Katerina , Anumol Tarun
Published: November 2022

Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic chemicals that have been applied in a wide range of industrial, commercial, and domestic products since the 1950s. Because of their toxicity, persistence, and bioaccumulation potential, PFAS have become global environmental pollutants. Besides the environment, the food chain represents another source of exposure, and the risk to consumers related to the presence of PFAS in foods has recently become of increased interest. In this respect, whole milk, infant formula, and ingredients used in infant formula production represent important foodstuffs that require sensitive methods with reporting limits at low parts per billion levels or lower for multiple PFAS. This article summarizes optimization experiments and validation of a complete workflow, including sample preparation and a liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for determination of sixteen priority PFAS analytes listed by the U.S. Food and Drug Administration (FDA).
A Novel High Selectivity Fluorimetric and Colorimetric Probe Based on Rhodamine B Hydrazide Derivatives for Detecting Hg2+ in Aqueous Media
Authors: Gui Kai , Yao Ying , Liu Hui-Xin , Fu Xu-Mei , Hu Jing-Han
Published: November 2022

A colorimetric and fluorescent dual-channel chemosensor (G1) with a simple structure was designed and synthesized to identify Hg2+ in an aqueous solution with high selectivity and sensitivity. After adding Hg2+, the color of G1 in the dimethyl sulfoxide (DMSO)/H2O (2:8, v/v) solution changed from colorless to a distinct rose red, whereas the fluorescence changed from colorless to bright orange under ultraviolet (UV) light. The detection limit on the fluorescence response of G1 to Hg2+ was as low as 6.09 × 10-7 mol/L. The results of the Job’s plot suggested that the combined stoichiometry between G1 and Hg2+ was 1:1. By successively adding Hg2+ and ethylenediaminetetraacetic acid (EDTA), the fluorescence process can be reversed and almost no fluorescence loss. In addition, G1-based test strips were produced and were able to qualitatively detect Hg2+ in tap water.

Effect of Fluid Invasion on the Failure and Deformation of Deep Coal and Wellbore Stability
Authors: Zhang Guangfu , He Shiming , Tang Ming , Liu Sen , Deng Fuyuan
Published: November 2022

A large number of studies have shown that there are numerous cleavage planes and cracks in coal rock, and these weak planes are the main factors affecting the mechanical strength of coal rock. In order to quantitatively study the mechanism, rock samples were soaked in three kinds of fluids, namely "clean water", "original drilling fluid" and "new drilling fluid with strong plugging ability" and then these soaked samples and dry rock sample were respectively tested by high-temperature and high-pressure triaxial mechanical tester. The failure and deformation law of coal rock were quantitatively described, and the influence of confining pressure, cleavage plane and fluid on the mechanical parameters (cohesion, internal friction angle, elastic modulus, Poisson's ratio) was analyzed. A model for predicting the collapse pressure of coal seam considering the effects of seepage and multiple cleavage planes was established. The mechanical parameters of dry rock samples and the rock samples soaked in original drilling fluid and new drilling fluid were introduced into the model to quantitatively explain the impact of fluid invasion on coal rock formation collapse.

Introduction

The Jurassic strata in the northern Kuqa area of the Tarim Basin are deeply buried, and there are multiple sets of coal seams in the J2kz-J1y layers, with a burial depth of about 3600 m~4800 m1,2 ( Wang, D.2018; Mao J,1999) Well collapse, leakage and diameter expansion often occur, which seriously affect drilling speed and cementing quality in the later stage, and restrict oil and gas production. Studies have shown that during the diagenesis of coal, a large number of cleats will be formed in the coalification stage3,4(Jian, B,2001; Cao, 2021), and these cleats will reduce rock strength. The drilling fluid intrudes into the cleat in the drilling process due to pressure difference, thus playing a lubricating role to a certain extent5 (Chen, 2013), which further reduces the mechanical strength of the coal matrix block and cleat 6,7,8 ( Wang, 2020; Li, 2022; Han, 2022) and is even more unfavorable for wellbore stability9 ( Wang, 2010).
Shale Stability – A Discussion on Lab Strength Testing and Wellbore Stability Predictions
Authors: Bautmans P. , Horsrud Per , Fjær Erling
Published: November 2022

Rock core samples may be tested by destructive methods to determine the material’s mechanical strength. These measurements may however introduce further uncertainties, which often evolve around how to apply the laboratory derived data to subsurface conditions. Indeed, strength discrepancies have been reported between cylindrical plugs and hollow cylinders, which suggest a geometry issue. A scaling concern also presents itself when using small laboratory samples to represent an operationally exposed rock volume. In addition, matching the correct failure model to the lab measurements is often ambiguous. This article reflects on these issues from a wellbore stability perspective. A case is presented where testing datasets (including both triaxial and hollow cylinder tests) are used to characterise the material’s strength suite. Implementing these findings to a wellbore stability calculation shows how an incomplete or poorly interpreted dataset may be misleading, thereby highlighting the inherent uncertainties and difficulties associated with borehole stability modelling.
