Authors: SINGH BABITA , SINDHU S S , ARORA AJAY , YADAV HARENDRA
Published: December 2022

The demand for salinity tolerant turfgrasses is increasing due to augmented use of effluent or low quality water for turf irrigation. Fresh water, coupled with soil salinization in many areas has resulted in an increased need for screening of salt-tolerant turfgrasses. Physiological responses to salinity and relative salt tolerance of four C4 turf grasses Cynodon dactylon (Bermuda grass), Zoysia matrella (Manilla grass), Stenotaphrum secundatum (St. Augustine grass) and Paspalum notatum (Bahia grass) were investigated during the study at Division of Floriculture and Landscaping, IARI, New Delhi 2015-2017. Turfgrasses were planted in plastic pots filled with sand: cocopeat: vermiculite (2:1:1) and irrigated with different concentration of salinity levels (50, 100, 200, 300, 400 and 500 mm). Salinity tolerance was evaluated on the basis of leaf firing, shoots and root growth reduction, proline content, total chlorophyll content and relative water content was subjected to analysis of variance. Among the four turfgrass species S. secundatum found to be most salt tolerant turf grass followed by Z. matrella while P. notatum was least tolerant turfgrass against salt stress.

The present field investigation was carried out during winter season of 2016-17 and 2017-18 at Rajasthan Agricultural Research Institute, Durgapura, Jaipur to evaluate the effect of different irrigation levels and moisture conserving polymers on performance of wheat. Results revealed that application of six irrigations resulted in significantly maximum plant height (at harvest) and dry matter at 60, 90 DAS and harvest. The application of six irrigations enhanced the CGR by the magnitude of 55.97, 23.36 and 27.55% (30-60 DAS), 42.87, 20.38 and 20.70% (60-90 DAS) and 71.09, 48.00 and 49.53% (90 DAS-at harvest) over control, three irrigations (at fixed interval) and three irrigations (at critical stages), respectively. The application of Pusa hydrogel resulted in significantly increased plant height, dry matter accumulation and CGR during all the growth stages.The maximum number of earheads (375.78/ m2), spike length (10.82 cm), number of grains/ear (30.84) and test weight (40.95 g) were registered with application of six irrigations. Pusa hydrogel improved the effective tillers by 3.61-7.31% and spike length by 8.20-15.70% over control and Herbal hydrogel. The mean maximum grain (4.74 t/ha), straw (5.73 t/ha) and biological yield (10.47 t/ha) were recorded with application of six irrigations. Pusa and Herbal hydrogel enhanced the mean grain, straw and biological yield of wheat by 6.65-13.69%, 6.90-14.41% and 6.79-14.09%, respectively. The application of six irrigations increased gross and net returns by magnitude of 64.14, 31.35 and 33.28% and 83.35, 42.25 and 44.98% over control, three irrigation (at fixed interval) and three irrigation (at critical stages), respectively. The highest gross returns (` 76924/ha) net returns (` 45548/ha) were recorded with application of Pusa hydrogel. Therefore, application of Pusa hydrogel provided additional net returns of ` 5689/ha to the farmers over control. The application of Pusa hydrogel and six irrigations to wheat using sprinkler system can be advocated as sustainable strategy for enhancing productivity and profitability of wheat cultivation in semi-arid condition.

Published: December 2022

A great stride is witnessed in area expansion under protected cultivation, particularly in arid-western parts of India, where cucumber (Cucumis sativus L.) is a predominant greenhouse crop. The early-summer crop of cucumber is highly remunerative owing to high prevailing market price. In current study, efforts were made to select suitable greenhouse cucumber hybrids for early season harvest under western Indian arid plains. Growth, yield and commercial quality traits of seven commercial gynoecious and parthenocarpic (seedless) cucumber hybrids were studied under greenhouse condition during 2015-16. Among the hybrids evaluated for early summer greenhouse production, Terminator was more precocious for fruit harvest (36 days after transplanting) followed by Rica and Dinamik. The per plant fruit yield was highest in Ekron (5.3 kg) followed by Terminator (4.2 kg). The vine length, leaf size and leaf dry weight were also found to be highest in Ekron, followed by Terminator. The fruit appearance, taste and texture, and overall consumerâ€™s acceptability were also determined, which were found better in Rica, Terminator and Dinamik. Despite exhibiting highest production related traits, Ekron measured least score for sensory parameters, especially the fruit appearance due to presence of rudimentary spines on skin, and also the taste. Fruit pericarp thickness and dry matter content were significantly higher in Ekron but the values were at par with that recorded for Terminator and a few other hybrids. The character association analysis reveals that per plant fruit yield had significant positive correlation with vine length, leaf size, foliar (stem+leaf) dry mass and mean fruit weight. Based on targeted characters for earliness, fruit yield and commercial quality of evaluated hybrids, it is concluded that Terminator followed by Rica were highly suitable for early summer production under protected condition in western arid plains of India.

Published: December 2022

An experiment was conducted in microplots at ICAR-Central Soil Salinity Research Institute, Karnal, Haryana during 2013–16 to study the adaptive response of Salvadora oleoides, a facultative halophyte under saline, sodic and mixed saline-sodic conditions. S. oleoides was not able to survive at higher sodicity (pH ~ 10.0) and salinity (ECe ~ 35 dS/m) as well as on the mixed sodicity and salinity levels (pH ~ 9.0 along with ECe ~ 10, 15, 20 dS/m). Stress either salinity or sodicity brought reduction in plant height, chlorophyll content and gas exchange attributes, but S. oleoides maintained gaseous exchange at moderate stress level. S. oleoides accumulated 4 fold higher proline under sodic stress and 6 fold under salinity stress. Other osmolytes, TSS and soluble protein decreased with stress intensification to maintain osmotic balance. In comparison to control, sodicity enhanced Na+ and Cl- by 54.57% and 20.33%, while under salinity, Na+ was enhanced by 141.52–256.09% and Cl- by 47.83–115.58% at ECe ~ 15 and 25 dS/m, respectively. Inspite of such higher increase in Na+ and Cl-, S. oleoides retained good amount of mean K+ (1.22%) in leaf tissue. S. oleoides also maintained leaf Na+/K+ below 1.0 under stress condition of pH ~ 9.5 and ECe ~ 15 dS/m. Based on the studied physio-biochemical analysis, Salvadora oleoides exhibited good adaptive potential under moderate salinity and sodicity stress and could be used as a promising salt-tolerant plant species for plantation in salt affected areas.

Authors: DARAVATH VEERANNA , CHANDER SUBHASH
Published: December 2022

An experiment was conducted at Department of Entomology, Indian Agricultural Research Institute, New Delhi during 2015–16 and 2016–17 to study the impact of elevated CO2 on functional response of wolf spider, Pardosa pseudoannulata (Boesenberg and Strand, 1906) against brown planthopper, Nilaparvata lugens (Stal, 1854) (Hemiptera: Delphacidae). Spider feeding rate on BPH was higher in jar arena compared to microcosm arena both under ambient CO2 and elevated CO2 conditions. Regression of number of attacked prey (1/Ha) upon prey density per unit area (H) over time duration of experiment (T) in microcosm and in jar arena under ambient and elevated CO2 revealed type II functional response. Attack rate, maximum attack rate and efficiency parameters were higher and handling time was lower in both jar arena and microcosm under elevated CO2 condition compared to ambient CO2 condition. Simultaneously, predators might have consumed more number of preys due to their poor nutrient quality under elevated CO2 compared to ambient CO2. It was revealed that with increase of predator density within the same prey density in same area under both ambient and elevated CO2 conditions, the prey control might have optimized. This information generated would support the planthopper management by regulating predator number for increased predator efficiency.
Direct and indirect methods used for the diagnosis of the Chagas disease in acute and chronic phase
Authors: Piloso Bazurto Nayeli Lisbeth , Valenzuela Sánchez Gabriela Paola
Published: December 2022

Chagas disease or American trypanosomiasis is an infection caused by Trypanosoma Cruzi. This flagellated blood parasite reproduces in tissues and organs. Chagas disease presents two phases. The acute phase can be asymptomatic and the chronic phase that is characterised by symptoms that could affect not only the digestive and nervous system but the heart. This review aims to depict the main diagnostic direct and indirect methods of Chagas disease which have been applied to acute and chronic phases respectively. However, Chagas disease diagnosis does have some limitations: low sensitivity of indirect methods, related to low blood parasite concentration, and low specificity of parasitological methods. Therefore, the WHO recommends that two tests should be performed in parallel on different principles or using different antigens to establish a proper diagnosis of the disease. Although there are several diagnostic methods, there is no specific test to diagnose this pathology, as the effectiveness of the diagnosis depends on the antigen used and the stage of the disease

Authors: Borah Biplob , Raju Chowhan L.
Published: December 2022

Considering the great prevalence of heterocyclic compounds in the core structure of numerous natural products, synthetic drug candidates, active pharmaceutical ingredients, and also in optoelectronic materials; tremendous efforts have been dedicated toward their synthesis and functionalization. But, the exploitation of hazardous, volatile organic solvents and toxic reagents caused disadvantageous effects on the atom economy and eco-friendly nature of the chemical transformation. Therefore, developing chemical processes providing easy access to complex target molecules by avoiding the utilization of hazardous solvents and reagents for making our environment toxic-free is of increasing significance for chemists in both academia and industry. The synergic combination of the features of mechanochemical activation as alternative energy input with the efficiency associated with small organic molecules that can catalyze chemical reactions is predominantly relevant to fulfill the goal of green and sustainable chemistry. This chapter is dedicated to providing a critical overview on the application of mechanochemical techniques for the synthesis of five- and six-membered heterocycles, as well as complex-fused heterocycles and spiro-heterocycles under organocatalytic conditions.
Cultivating Trust in Employee Relations
Authors: Mhango Lydia
Published: December 2022

At the heart of employment relations is the desire of both management and employees to create an ideal and efficient and effective organisation. However, this does not always happen, and both employers and employees and their representatives share the blame. For employees and their representatives, the “us against them” attitude is a catalyst for distrust. For employers, inflexibility and autocratic leadership styles make effective human resource management extremely difficult. Through interviews with management and union representatives, this experimental research explores causes of distrust, offers solutions and ends by suggesting the adoption of the Soft Human Resource Management (SHRM) approach as a solution to enhance trust in employee relations. The study focused on trust in organisations that have unionised workers.

Published: December 2022

The stress concept, first proposed by Hans Selye in 1936, has also been applied to plants to describe adverse and environmental restrictions. The notion of plant stress, differs significantly from that of animals and humans. Due to ever fluctuating climatic circumstances and variables, the crop-environment interaction in horticultural crops leading to losses in yields and quality of produce occurs and thus climate change with respect to horticulture industry is attracting more attention. Abiotic stress is the leading cause of crop yield loss globally, lowering average yields by more than half for most main crop plants. Abiotic stressors are highly correlated and connected, causing morphological, biochemical, physiological and molecular changes in vegetable crops, leading in a significant profit drop. Water stress is the most common abiotic stress that causes significant losses in vegetable production, especially because it is often coupled by additional stresses like as salt, high temperatures, and nutritional deficits. Increased CO2 and temperature in the atmosphere, variation in amounts of precipitation causing more frequent droughts and floods, widespread runoffresulting in soil nutrient leaching and a loss in fresh-water availability are all contributing factors. Efforts to mitigate various pressures should be focused both throughout the growing season and after harvest. Stress-tolerant cultivars are being developed using a variety of methods, including traditional breeding and transgenic technology. Instead of genetic engineering, using vegetable breeding procedures or directed breeding is one the best options to improve stress tolerance in vegetables. Besides, post-harvest treatments, application of growth regulators, antioxidants, germplasm and in vitro selection, and modified environment packaging with different plastics may all help to improve tolerance and hence increase the shelf and nutritive life of vegetables.

Role of Various Physicochemical Factors in Enhancing Microbial Potential for Bioremediation of Synthetic Dyes
Authors: Birmole Radhika , K. Samudravijay Aruna
Published: December 2022

The Indian dye industry is globally recognized for production and export of every known class of dye. On the less attractive side of industrialization, they contribute considerably to environmental pollution. The dyes discarded by industries persist in the environment due to extremely slow rate of biodegradation. Moreover, these dyes are toxic to insects, birds and terrestrial life. The dyes also hamper the light penetration in water bodies, severely affecting the the process of photosynthesis. In spite of the problems associated with synthetic dye disposal, they are industrially preferred due to their fundamental requirement in enhancing overall appearance of goods, quality and cost effectiveness. Several studies have reported physicochemical techniques for remediation of dye effluents. Most of these techniques pose significant drawbacks due to their high energy and cost requirements. The bioremediation approach, on the other hand, offers advantages of sustainable environmental friendly processes to detoxify and degrade dyes into harmless products. This chapter provides an overview of the potential role of various physicochemical factors such as pH, temperature, oxygen and nutrient concentration in optimum decolorization of dyes by naturally isolated microbial strains. In addition, the role of cosubstrates, electron acceptors and microbial enzymes are also discussed.

Synthesis of Schiff Bases by Non-Conventional Methods
Authors: D. Adesina Adebimpe
Published: December 2022

A Schiff base is a compound with the general structure R1R2C=NR’. They can be considered a subclass of imines. The term Schiff base is normally applied when these compounds are used as ligands to form coordination complexes with metal ions. Schiff bases can be synthesised from a primary aliphatic or aromatic amine and a carbonyl compound by nucleophilic addition forming a hemiaminal, followed by a dehydration to generate an imine. In other words, a Schiff base is a nitrogen analogue of a ketone or aldehyde where the carbonyl group has been replaced by azomethine or imine group. The imine group present in these compounds has been shown to be critical to their biological activities. Schiff bases have been frequently used in various fields such as medicine, pharmaceutical purposes due to their wide range of industrial applications. The unconventional methods of preparation of Schiff bases, compared with traditional methods, are more convenient, and reactions can be carried out in higher yield, shorter reaction time and milder conditions, without generation of pollution and safer to analyse.

The Covid-19 pandemic has affected the work, personal, and family lives of all Czechs. In this regard, single parents are one of the most vulnerable groups. They are very frequent recipients of external support, provided by the state or by grandparents. Government restrictions, accompanied by, among other things, reduced availability of institutional childcare services, have significantly increased parents’ demand for informal childcare. However, grandparents have not been able to fully satisfy this demand. Within the proposed typology, the so-called risk group of single parents who did not receive the required childcare support concerning school preparation or free time, as well financial or material help, was identified. The size of this group grew during the pandemic. According to regression analysis, parents of preschool and younger school children, working in precarious forms of work, in a low-income situation, and/or in rental housing, were at higher risk of falling into the group of single parents who need informal support

Published: December 2022

Cattle farming is an intensive branch of agricultural production, a market for the means of production and industrial products, a source of income for the economy and a means of superior capitalization of natural resources (CARP-CARARE, 2004). Among cattleproduction, milk is the most important due to its complex chemical composition, biological value, and a high degree of digestibility, it contains over 100 substances necessary for the human body. The colostrum subperiod lasts from the birth of the calves to the age of one week. In this subperiod, the calves are fed exclusively with colostrum, which maintains the connection between the organism of the newborn calf and the maternal one. In this paper the experimental data came from twelve cows of the Spotted with Romanian black breed from the farm located in Covaci, of which five cows are primiparous and seven multiparous. The samples were analyzed using the MilkoScan apparatus for the determination of protein, fat, lactose and dry matter. In multiparous cows the average daily protein concentration (6.85%) is lower (p> 0.05) by 1.13% than that recorded in the case of primiparous cows (7.98%), distinctly statistically significant difference.The coefficient of variability has the value of 57.743 in primiparous cows and 59.735 in multiparous cows. Colostrum milk samples were taken every four hours, immediately after calving, for three days (18 milks/cow), resulting in 90 samples in primiparous cows and 126 samples in multiparous cows.Colostrum samples were collected every 4 hours during the first three days (72 hours) after parturition.

Authors: AGAPIE Alina Laura , BOSTAN Cristian
Published: December 2022

Improving the quality of wheat is one of the major objectives of plant breeding programs, wheat being one of the most cultivated plants due to its significant share in human nutrition. In order to obtain quality bakery products, the processed grains must have a high protein and gluten content. This paper aims to analyze the influence of mineral fertilization with nitrogen and phosphorus on the accumulation of protein and gluten in the Ciprian wheat variety (created by ARDS Lovrin, in the period 2018-2020. Ammonium nitrate (33.5%) was used as a nitrogen fertilizer; the following graduates were used in the experiments: N0, N30, N60, N90 and N120. Phosphorus graduations was P0, P40, P80, P120 and P160. The analyzed parameters were: protein, gluten and starch. As a percentage, the three parameters are very significantly influenced by the amount of fertilizer administered but also by the climatic conditions of the agricultural year. Of the two types of fertilizers studied, both unilaterally and in interaction, nitrogen has a fundamental role in obtaining valuable qualitative productions for winter wheatThe percentage of protein and gluten varies in the range 11.2% - 14.7% (protein), respectively 27.81% - 38.56% (gluten), with very significant differences from the control variant, at all levels of nitrogen fertilizers, statistically assured for the probability of transgression of 0.1%. In contrast, under the action of mineral fertilization with nitrogen, the percentage of starch in the grain decreases proportionally with the increase of the administered dose. The unilaterally applied phosphorus does not bring significant changes of the studied qualitative parameters, but being used as a support for nitrogen. The highest values of protein and gluten are registered at the combined administration of the two types of fertilizers, with a visible capping at the maximum doses administered to the wheat crop.

Nitrogen has its undeniable role in increasing crop productivity and quality. However, used improperly, it can cause serious environmental damage. Increasing the efficiency of the use of chemical nitrogen fertilizers (NUE) is a goal of the future¸ necessary for a sustainable and competitive agriculture. The wheat crop studied is part of a long-term experiment, established in Lovrin in 1967. The experimental factors studied are: factor A - nitrogen, with the following graduations: N0, N30, N60, N90 and N120 and factor B - phosphorus, with the following graduations: P0, P40, P80, P120 and P160. From the combination of the two studied factors  results  25 experimental variants,  placed in the field according to the method of subdivided plots, in four repetitions. Chemical fertilizers with phosphorus - 46% superphosphate - were administered to the wheat crop in autumn and were incorporated under the basic plowing. Nitrogen fertilizers - 33.5% ammonium nitrate - were applied in fractions: 40% of the dose at start of vegetation, in the spring and 60% at straw elongation. The wheat culture is part of a three-year crop rotation - soybeans-wheat-corn. Following in rotation after soybeans, no nitrogen fertilizers were applied at the establishment of the crop. The variety studied is the Ciprian variety, created at SCDA Lovrin. For the evaluation of NUE, Plant N Uptake, Nitrogen Use Effciency and Partial Factor Productivity were analyzed in this paper. In the climatic conditions of the two experimental years, a distinctly significant positive correlation is established between the nitrogen dose administered and production, the value of the correlation coefficient being 0.56 **. Between the nitrogen dose, the protein content and the amount of protein per ha the correlation is very significant, with the following values ​​of the correlation coefficients: r = 0.96 *** (for protein) and r = 0.90 *** (for N uptake). Nitrogen use efficiency correlates negatively, very significantly, with the administered dose - r = -0.87 ***. This study also reveals the importance of phosphorus in the absorption and accumulation of nitrogen in wheat caryopsis. The amount of nitrogen accumulated increases with increasing dose of phosphorus, up to 80 kg ha-1, with the gradual reduction of the amount accumulated to high values ​​of phosphorus administered (120 kg ha-1 and 160 kg ha-1, respectively).

Soybean is one of the most important sources of vegetable protein, having a great agronomic importance by fixing atmospheric nitrogen following symbiosis with bacteria of the genus Rhizobium. Bifactorial experience, of the AxB model A - phosphorus doses: P0; P40; P80; P120; P16 and B - nitrogen doses:N0; N25; N50; N75; N100, aims to identify the influence of these doses on the development of soybean cultivation. Although soybeans are a heavy consumer of nitrogen and phosphorus in the early stages of development, however, they do not react well to large amounts of nitrogen as they prevent the development of the number of nodules on soybean roots and inhibits the growth of bacteria, and the increases obtained production do not justify the higher amount of nitrogen applied to soybeans. The number of pods and the mass of 1000 grains are also influenced more by the application of phosphorus doses than  nitrogen. Phosphorus applied in higher amounts leads to an increase of over 60% of the number of nodules but also at significant production increases of 5-7%, compared to the non-fertilized variant. On nutrient-rich soils, soybeans do not require fertilization with large amounts of nitrogen, but they react very well to the application of phosphorus fertilizers.
Significados de surdez segundo professoras de Venturosa no Agreste pernambucano

Published: December 2022

Este artigo é um recorte de uma dissertação que teve como objetivo compreender os significados de surdez construídos por professoras da cidade de Venturosa, visibilizando, desta forma, o Agreste pernambucano. Teoricamente, partimos do conceito de “significado”, entendido como construção socialmente compartilhado e constitutivo de modelos indutivos que possibilitam professores a lidar com o imprevisível em sala de aula. Consideram-se o campo em disputas das práticas pedagógicas com a população surda. Do ponto de vista metodológico, 49 professoras responderam a um questionário contendo dez questões abertas e uma escala Likert com 20 itens. Os dados ilustraram uma distância entre o conceito de surdez e a prática profissional de professoras que não convivem com pessoas surdas e/ou com pouca aproximação com a Libras. Estes resultados evidenciaram as posturas que fazem diferenciar a surdez e a deficiência auditiva: presença da fala oral, momento de aparecimento da surdez e nível/grau da audição. Notou-se também uma sensibilidade das participantes ao modelo inclusivo, apesar de uma dificuldade de implementação na educação regular e uma resistência à educação bilíngue (Português-Libras). A invisibilidade científica de regiões como o Agreste Pernambucano justifica estudos que denunciem a defasagem de formação, tanto inicial quanto continuada, longe das metrópoles. Nesse campo de disputas, as professoras lidam com suas defasagens, seus pertencimentos e uma prática que não consegue ser prescrita por completo, já que as “receitas” não funcionam.
Me, others and shame: Students undergoing Gestalt psychotherapy training and the feeling of shame
Authors: Opačić Snežana , Jovanović-Milanović Olja
Published: December 2022

Internalized shame is the feeling that there's "something wrong" with our entire being, that we are unworthy of existence and belonging. Although shame is normally perceived as a solitary kind of pain, it is always relational in nature. Shame always accompanies the learning process in the education of future psychotherapists, as specific methods of experiential learning and quality demands provide fertile ground for shame emerging among the process participants. A more permanent recovery of the feeling of self may only emerge through the experience of another's authentic interest for our inner world and through the feeling of being seen and accepted. The goal of the research is to contribute to the understanding of others' role in the emergence and dynamics of shame in the context of the educational-experiential group. The research comprised 15 students in their 1st, 3rd and 4th year of Gestalt therapy training. We collected data by means of critical incident technique. Two qualitatively different themes emerged through the thematic reflexive analysis: me-that and shame, and me-you and shame. We analysed the findings from two perspectives-the relational paradigm of shame and transformative adult education.
Analysis of the mining activities impact on the content of heavy metals in the groundwater and drinking water depending on climate parameters

Published: December 2022

The purpose of this analysis is to show whether mining activities have an impact on the grondwater and drinking water quality. Water samples were analyzed in three unfavorable climatic periods during the winter of 2018-2019. The obtained results show that the heavy metal concentrations in water samples do not have values higher than the allowable according to the current statutory regulations. Also, the heavy metal concentration did not change with changes in climate parameters. However, a higher concentration of molybdenum than statutory by the law was found in the period of snow melting. This has shown that in extremely unfavorable climatic conditions, the karst groundwater can contain certain metals that can origin either from the surrounding field or as a result of mining activities, considering that there are two open pits s in the immediate vicinity of the "Surdup" source.

Climate change and the role of central banks
Authors: Martin Vesna
Published: December 2022

In the last few years, central banks have been exposed to new challenges and tasks that they need to face. One of those challenges is climate change, which directly affects the central bank's main goals, namely achieving and maintaining price and financial stability. In order to fulfill the goals defined by the Paris Agreement, it is necessary for central banks to take a more active part in the fight against the consequences of climate change. This means that central banks are expected to adopt policies and strategies that will guide the financial sector to successfully manage the risks of climate change and encourage them to direct investments in clean technologies and low-carbon infrastructure. This would achieve sustainable economic development in the long term, which is based on the principle of reducing the risk of climate change, while at the same time preserving the environment.
