Effect of drought stress on antioxidants activity in response to yield and its attributes in different Brassica juncea (L) cultivars
To identify the responses of enzymatic and non-enzymatic antioxidant activities in response to yield the study was undertaken in different Brassica juncea cultivars such as Pusa Bold, RSPR-01, RSPR-03, Kranti and NRCDR-2 under drought stress conditions at 45, 60 and 90 days respectively, days after sowing (DAS). The study was done in the Division of Plant Physiology, Chatha, SKUAST, Jammu during Rabi 2016-17, a pot experiment was conducted with factorial completely randomized design with three replications. Parameter such as relative water content in leaves, relative stress injury, antioxidant enzymatic activity, proline content, number of seeds per pod, number of pods per plant, 100 seed weight and seed yield were also studied. To determine the relative tolerance of genotypes, the drought susceptibility index (DSI) for seed yield and its attributes were recorded. The activities of enzymatic antioxidant such as superoxide dismutase (SOD), peroxidase (POX) and non-enzymatic antioxidant ascorbic acid preferentially enhanced by the drought stress. Relative water content, dry weight decreased, whereas relative stress injury, proline content increases with the increase in the drought stress given at various days after sowing. At flowering stage reduction in seed yield was observed when drought stress imposed and it also affects silique development. It was noticed that reduction in seed weight was minimum when drought stress was induced before flowering. These results indicate that protection from oxidative damage by higher levels of antioxidants may be involved in the development of drought tolerance in Brassica juncea. These biochemical parameters results can be used as practical for selection of drought tolerant brassica juncea genotypes when selecting drought tolerant cultivars for breeding in arid regions.
Seroprevalence of bovine brucellosis in Algeria and impact on the health of professionals
In Algeria, although a control plan (screening and slaughter) has been in place since 1995, the evolution of animal and human brucellosis remains variable from year to year. The present investigation is carried out with the aim of determining the prevalence as well as the insufficiencies of the applied control plan. For this purpose, 100 blood samples of cattle, distributed over 19 visits, were taken during the month of April 2020 in the slaughterhouse of Sidi-Bel-Abbès. Data related to age, identification, breed, type of slaughter, pregnancy, and the presence of metritis were also collected. In addition, 10 sets of volunteer professionals from the same establishment had their socio-epidemiological information collected. Thus, all sera were analyzed by the buffered antigen test (BAT) and the Wright test. The results obtained show, on the one hand, a 3% positivity to the EAT and compliment fixation (CF) in slaughtered cattle and 0% in professionals, and, on the other hand, an overall rate of 10% daily occurrence of brucella cattle within the slaughterhouse. In addition, 2.80% of the cattle slaughtered in the framework of sanitation are positive. While no difference in prevalence related to breed, identification status, or age is recorded, In fact, the uncontrolled movement of animals was found to be a limiting factor in the effectiveness of brucellosis control. These results encourage the application of strict prophylactic and preventive measures against brucellosis and the renovation of slaughterhouses and killings in Algeria.
India’s Trade Deficit with the GCC Countries Compensated by Remittances
India’s economic cooperation with GCC countries has been going on for many decades and growing over time. India has huge resources based on agriculture, while GCC is an economic organisation that comprises six oil-based economies (Saudi Arabia, UAE, Kuwait, Qatar, Oman, and Bahrain). And it generates a huge share of their national income from producing and exporting petroleum oil. With time India’s economic cooperation with GCC economies is growing in size and importance. Both India and the GCC countries are crucial for bilateral energy cooperation. The available information on India’s growing export trends of goods and services confirmed its growing importance in the GCC market. Migration of expatriate labours is predominantly a commodity in Indian exports of goods and services to Gulf countries. Exports of human capital to GCC countries play a crucial role in the economic growth and development of GCC economies while improving trends of Indian imports from Gulf countries also shows that significant increment in importance for GCC’s petroleum oil exports. GCC exports detailed characterised by plenty of Petroleum oil. India is a labour-exporting country, while GCC economies are the main petroleum oil exporters. As India received a substantial amount of remittances, and GCC economies received massive oil revenues. Consequently, India is facing a deficit in its balance of trade with GCC economies. This India’s trade deficit with GCC economies may be compensated by the inflows of remittances received from Gulf countries. Commodities like Basmati rice, spices, various vegetable oil, and manpower are the most important export items to GCC countries. Petroleum oil and petroleum products are the most important imported items from India to GCC economies. Important statistical tools like the growth rate of exports and imports have been used in trade analysis. This study covers ten years period that has been taken for discussing economic cooperation.
Modeling and Optimization of the removal of the dye "Methylene blue" from wastewater by the physical-chemical coagulation-flocculation process at different pH values and agitation speeds
Our investigation included the study of the efficiency and applicability of a physico-chemical process called coagulation-flocculation for the treatment of textile industry wastes contaminated by textile dyes: Methylene blue using aluminum sulfate as a flocculant coagulant. Coagulation-flocculation performances: The results obtained showed that by optimizing various parameters (pH value, decoagulant dosage, initial solution concentration and agitation speed), the process was more efficient with a yield close to the total abatement threshold (i.e. 95%) for the 2.5mg/L coagulant concentration.
SHEARING CHARACTERISTICS of SOYBEAN STEM AFFECTED by GREEN STEM SYNDROME
Recently, the Green Stem Syndrome (GSS) which prevents the stems from drying down properly and causes the stems to remain green after seed are mature has been often seen in the soybean fields in Türkiye. As known, the green stems are hard to cut and more likely to plug the combine. This situation causes to increase the losses during harvest. From this point of view, in this study, shearing stress and specify shearing energy of the stem were determined in order to obtain basic data for obtaining working conditions to reduce harvest losses in GSS-captured soybean plants. The shearing tests were performed with a Lloyd Material Testing Machine (model LRX Plus) equipped with a shearing apparatus. Six different soybean varieties namely, Türksoy, Ataem-7, Cinsoy, Blaze, SA-88 and ÇU04-122 were used as plant material. All experiments were carried out in 20 replicates. The average moisture content of the stem was 63.13% in syndrome plants and 22.60% in healthy plants.It was determined that the values of shearing stress and specific shearing energy of the plant stem with and without syndrome were statistically different. All parameters investigated in the study except shearing stress were found to be higher in GSS plants. In plants with syndrome, plastic cutting (crushing) has come to the fore instead of solid cutting. This has been assessed and discussed as one of the reasons to increase losses in cutting and blending operations during harvest.
