The Malaprabha river basin is one of the natural regions, with agriculture being the lifeline activity of the inhabitants of the basin. However, surprisingly, the region experiences greater regional disparities in overall development in general and agricultural development in particular. Regional disparities in the river basin may be natural due to unequal distribution of natural resources or man-made in the sense of neglect of some regions and preferences for others for investment and infrastructural facilities, and to some extent, the developmental policies of the region. The present study has utilized the published sources of data and reports collected from the Directorate of Economics and Statistics, Govt. of Karnataka, the Directorate of Census Operations in Karnataka, Govt. of India, Bangalore, and other related statistical records at taluka level at two points in time, i.e., 1993–94 and 2013–14. Though the study area is a natural region, the taluka has been taken as the smallest unit of study. The findings suggest that significant disparities have extensively affected the various aspects of agricultural development in the talukas of the river basin. The areas with a low level of development should be given top priority so that they may come up at par with the developed areas and the concept of planning with social justice may be fulfilled.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":" 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140685782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollen grains are notably more susceptible to pollutants compared to other parts of the plant. However, in polluted environments, certain metals like lead (Pb) and cadmium (Cd) may have limited bioavailability, posing significant challenges to the phytoextraction process. One way to overcome this limitation is by employing chelators. The experiment was conducted in a randomized block design to investigate the effects of two chelators, EDTA and salicylic acid (SA), in enhancing the plant water status, biochemicals and reproductive parameters of Brassica juncea seedlings. These seedlings were sown in pots and subjected to various treatments of Cd and Pb of concentrations 10 and 20 mM, either alone or in combination with 0.5 mM EDTA and SA. The toxicity induced by Pb and Cd in B. juncea was recorded through decreased levels of osmotic potential in leaves and roots and decreased leaf chlorophyll content. Additionally, various reproductive parameters, including pollen viability, pollen germination, and in-vitro pollen germination, were highly affected by stress. Conversely, the supplementation of EDTA and SA to Cd, and Pb-treated plants effectively mitigated the negative impact of heavy metal stress by increasing osmotic potential, chlorophyll content, and reproductive parameters. Notably, EDTA and SA also significantly increased Pb and Cd accumulation. The result demonstrates the potential of EDTA and SA in improving plant reproductive biology.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"8 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140715114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trichoderma is a genus of ascomycete fungus that lives in soil and is known for its ecological significance as a bio-fungicide.\u0000Aim: The current study aimed to assess and contrast the antagonism and exoenzyme activity of Trichoderma isolates against Pythium sp., which causes damping-off and root rot diseases on tomato plants. Trichoderma spp. was isolated from rhizospheric soil of healthy plants in the agricultural fields of Patna, Bihar district, India.\u0000Methodology: The Trichoderma isolates were evaluated for their suitability as antagonists by in vitro dual culture and non-volatile assay.\u0000Results: The results showed that the isolated Trichoderma species were effectively reduced the growth of Pythium sp. in the dual culture assay and non-volatile metabolites (12.5%, 25% and 50% v/v concentration) assay. Trichoderma atrobrunneum effectively inhibited the mycelial growth of Pythium sp. both in the dual culture (81.48%) and non-volatile metabolite assay (71.37%). Followed by Trichoderma harzianum (79.01% and 58.82%), and Trichoderma asperellum (65.43% and 50.58%) respectively. Exoenzyme activities of the Trichoderma isolates were also investigated. The antagonistic Trichoderma atrobrunneum exhibited maximum activities of β-1,3-glucanase (41.39 U/ml) and chitinase (33.06 U/ml) in comparison to T. harzianum and T. asperellum. The capacity of antagonism is enhanced by the production of the enzyme. Based on the above results, it can be said that the non-volatile metabolites and the exoenzyme of the antagonist T. species act synergistically in inhibiting Pythium growth.\u0000Conclusion: The secretion of enzymes by Trichoderma species shows that they can be used in plant disease control as novel biocontrol agents as well as to produce enzymes in biotechnological processes.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"80 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140747243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple reviews have been published compiling the effects of NPs on different illnesses. However, a few reviews are available regarding the impact of NPs on liquid tumors. Therefore, this review aims to advance knowledge in this direction by drawing conclusions from research on Dalton’s lymphoma (DL), a type of T-cell lymphoma, for the therapeutic implication for liquid tumors. NPs synthesized from both metals (such as silver, gold, copper, and zinc) and nonmetals (such as silica, selenium, polymer, and lipid-based) have been tested for their anticancer efficacy against DL. These NPs reduce the viability of DL cells in a dose-dependent manner by inducing apoptosis. In mice, NPs increase the lifespan, reduce tumor growth, and restore the normal physiology and structure of organs such as the liver, spleen, and kidney. NPs synthesized from plant sources or through some chemical compounds proved effective in reducing the cytotoxicity of NPs. This review will provide basic information on DL and discuss the various types of NPs used against it, their significance for therapeutics of T-cell lymphoma or liquid tumors and conclude with some major findings that can guide future research in this field. By synthesizing the latest research on NPs and DL, this review will serve as a valuable resource for researchers and clinicians alike in their efforts to combat liquid tumors.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139357856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its national average yield remains lower than the potential yield obtained at research stations. This is because of low soil fertility, inappropriate plant spacing, disease and insect pest problems. As a result, this experiment was carried out during the 2021 to investigate the impact of blended NPS fertilizer rates and spacing between crops on the growth and yield of common bean and to analyze the economic feasibility of blended NPS rates with common bean spacing. A four-factorial combination of mixed NPS levels (0, 50, 100 and 150 kg ha-1) and three row spacing (30, 40, and 50 cm) were used in a three-replicate randomized complete block design. After collecting plant phenology, growth, yield, and yield attribute parameters were analyzed by using SAS version 9.3 software. The results revealed significant differences for the main effect of the NPS blended fertilizer, row spacings, and their interaction on most of the measured phenological, growth, yield, and yield attributes of the common bean, however, neither the main effect nor the interaction effects affected seedling emergence. The combined use of 150 kg of mixed NPS ha-1 with a row spacing of 40 cm resulted in a higher grain yield (2.5 t ha-1) and maximum net benefit (41775 ETB ha-1). Hence, it can be established that earlier mentioned NPS fertilizer rate and row spacing isa better choice for farmers in the area and similar agro-ecologies in order to achieve the highest possible grain yield and a higher net return.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134088817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equipment especially, the actuator is operated continuously in the industries in order to achieve the desired production rate. Actuator is the key element which undergoes degradation due to frequent control actions. However, degradation is mainly influenced by different operating conditions and other environmental factors. This decreases the lifetime of the equipment and also it increases the maintenance cost. This problem is addressed by carrying out the reliability studies on the actuator by using Gamma process. It is used to describe the system  degradation.\u0000In this work, Gamma process based actuator modelling is used to study the deterioration in the actuator. The gamma parameters such as shape and scale parameters are the deciding factors describing the level of degradation in the system. It is then applied to two tank feedback control system.
