This experiment aimed to explore the possibility for mass-scale breeding and larval rearing of goldfish under biofloc setup. Natural brooders were collected, acclimatized and induced to breed utilizing synthetic hormones at various dosages. Breeding execution parameters namely spawning success, fertilization rate and hatching performance were analysed. The highest fertilization and hatching rate were gradually noticed at 80.8% and 80.9% by using a dose of 0.4ml/kg body weight for females and 0.2ml/kg for males. Larval rearing was accomplish by applying several live and formulated feeds across various life stages in normal rearing tanks and biofloc tanks also. The growth performance of larvae in biofloc tanks express a satisfactory rate, with a maximum weight gain of 7.1 g and length gain of 5 cm over 120 days compared to 5.1 g and 3.5 cm in normal tanks. Water quality parameters were kept within the optimum range all over the experiment. The functionable study exhibits the viability of captive breeding and mass scale larval nurturing of goldfish employing induced breeding techniques and biofloc technology.","PeriodicalId":91191,"journal":{"name":"Advances in research","volume":"41 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141660728","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}

It has been used as a fibre with various resins to produce composites. If burnt it produces ashwhich contains 90% Silica which has high abrasive strength and can contribute to mechanical strength of composites. In the present work RHA was obtained by incinerating RH at about 6000C for 6 hours. The ash obtained with this procedure is shiny white in colour and rich in silica. The ash obtained by this process was mixed in various weight proportions with epoxy and powdered rice husk to obtain bio composites. Mechanical tests were conducted to assess the strength of the composite. It was observed that incorporation of RHA as a fibre improved various mechanical properties upto a certain weight proportion where after it started decreasing. SEM tests were conducted to understand the failure mechanism. It can be concluded that RHA can be a suitable fibre for bio composites up to a limited range. In future however better casting techniques can be developed to utilize the abrasive strength of this abundant resource.","PeriodicalId":91191,"journal":{"name":"Advances in research","volume":"38 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141660364","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 HP extraction sources and the chemical diversity of its structural chain result in different clinical responses. In this study, a comparison was made among the effects of unfractionated heparin from bovine (bovHP) and swine (swi.HP) sources and low molecular weight heparin (LMWH) on skin lesions treatment. \u0000Study Design: Wounds were induced on the back of Swiss mice using a punch. Then, the wounds were treated with heparins for 3 and 7 days. \u0000Place and Duration of Study: Institute of Biomedical Sciences and Animal Breeding Network and Rodents of the Federal University of Uberlândia, between April 2018 and February 2020. \u0000Methodology: Wound closure was performed with a digital caliper. The inflammatory infiltrate was assessed by the activity of neutrophils and macrophages. Angiogenesis was measured by quantifying blood vessels and measuring hemoglobin. While fibrogenesis was assessed by picrosirius red staining. \u0000Results: None of the heparins had a healing effect. Swi.HP showed delay in wound closure and intensification of the inflammatory process compared to bov.HP. Swine and bovine heparins showed pro-angiogenic activity, although this did not differ between them. Difference between the groups of heparins was observed in relation to the deposition and organization of collagen fibers, with a reduction in fibrogenesis in wounds of the LMWH group compared to the other heparins, especially bov.HP. A better fibrogenic activity was observed for bov.HP. \u0000Conclusion: Thus, we conclude that the source of the heparin used should be considered, as its pharmacological response for wound treatment is quite diverse. Although none of the heparins was able to accelerate wound closure, bov.HP had an anti-inflammatory and pro- fibrogenic effect compared to the other heparins and therefore showed the best response in this experimental model.","PeriodicalId":91191,"journal":{"name":"Advances in research","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141664302","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}

In the last few decades the concern regarding farm women have been raised globally. There is immediate need to equip these farm women with relevant knowledge and skill. It is only possible if appropriate and relevant Information communication technology (ICT) tools are made available to farm women to get information related to agriculture. The present study was conducted in the Udham Singh Nagar district of Uttarakhand state to identify the constraints faced by farm women while using ICT tools. Garrett ranking was used. For this study, respondents were selected by using a Probability proportional to size (PPS) sampling method. To derive the inferences of the study, two blocks were selected for the present study. The study covered four villages & it covered 120 farm women in the selected villages. Data for the study was collected during 2019-20. Primary data was collected from farm women through personal interview method with the help of a pretested schedule. The main personal constraints noticed were lack of preference in using Information communication technology (ICT), lack of training, lack of confidence, lack of motivation and lack of time to utilize Information communication technology (ICT).

The research shows that the surrounding rock grade is closely related to the dynamic response and damage characteristics of the lining structure of the water conveyance tunnel. The dynamic damage of the tunnel under grade Ⅲ surrounding rock is only 0.08, which is far less than 0.83 under grade Ⅳ surrounding rock. It can be considered that it will not cause great damage to grade Ⅲ surrounding rock under earthquake. The surrounding rock grade is better, which can provide more stable support and reduce the stress and vibration of the structure. If the tunnel is in the seismic zone, the buried depth can be used as one of the design control indexes in the tunnel design. The lining damage is mainly distributed at the top and upper arch waist of the tunnel. With the increase of the buried depth of the tunnel, the dynamic damage amount increases from 0.021 to 0.081, then to 0.085. the damage of the lining structure also increases. This may be because the deep buried tunnel is more constrained by the underground rock and soil layer, thereby reducing the transmission of seismic load. The change of seismic wave intensity can directly affect the damage characteristics of tunnel lining structure. The dynamic damage mainly occurs at the vault and arch waist, and the damage area expands from the vault and arch waist to the side wall and corner. The increase of seismic wave intensity will lead to dramatic changes in the stress of the structure, which will lead to more complex and serious damage.","PeriodicalId":91191,"journal":{"name":"Advances in research","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141716730","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}

This paper reviews the current research status of seismic response analysis methods for underground structures, focuses on the basic principles, advantages and disadvantages, and applicability of the proposed static method and dynamic time course analysis method. It also analyses their applications in engineering. It is shown that the seismic coefficient method, although simple, may have relatively large calculation errors due to oversimplification. The free-field deformation method is simple in form and easy to implement, but ignores soil-structure interaction. The flexibility coefficient method is simple in form and considers soil-structure interaction, but ignores many factors. The reaction displacement method directly reflects the soil-structure interaction, but the foundation spring parameters are difficult to value. The reaction acceleration method has the same advantages as the reaction displacement method, but there is a certain error. The dynamic time-course analysis method is accurate but computationally intensive.","PeriodicalId":91191,"journal":{"name":"Advances in research","volume":"5 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141700373","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}

Adoption of sustainable cultivation practices addressing the principles of regenerative farming can build resilience in tea production and also lessen the negative impact on the environment. A sustainable initiative was taken by Goodricke Group Limited in collaboration with Inhana Organic Research Foundation (IORF) towards restoration of soil quality, crop sustainability and reduction of pesticide usage. To meet the set targets Inhana Rational Farming (IRF) was the adopted as the crop technology, which focused on soil and plant health management. The study encompassed two time periods, i.e., the pre-COVID era (2013–2019) and post-COVID era (2020–2022), during which crop performance, pesticide usage and soil quality development were documented. The findings clearly showed the impact of sustainable initiative in terms of better crop performance, lowering of pesticide use and improvement of soil health (where ever soil management was continued). This study clearly indicated that an investment in the sustainability account not only ensures crop sustenance and improvement in the long run and enable a reduction in the requirement for agrochemicals, of higher importance is the regeneration of soil health and improvement of resilience towards climate impact, which is critical for both present and future sustenance of the plantation as well as better economic security.","PeriodicalId":91191,"journal":{"name":"Advances in research","volume":"48 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141349579","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}

Employing a targeted yield methodology, the investigation centered on the cultivation of fodder sorghum as the exhaustive crop during the kharif season. \u0000Adhering to an inductive-cum-yield target approach, the experimental plot was meticulously partitioned into three equitably-sized strips, each delineating a distinct fertility gradient. These gradients were meticulously established through the application of varying fertilizer regimes: N0P0K0, N1P1K1, and N2P2K2. Notably, the recommended fertilizer regimen (N1P1K1) encompassed precise quantities of essential nutrients, specifically 60 kg ha-1 of nitrogen (N), 345 kg ha-1 of phosphorus pentoxide (P2O5), and 96 kg ha-1 of potassium oxide (K2O). \u0000Fodder sorghum emerged as the strategic choice for the exhaustive crop, strategically cultivated to expedite the transformation of applied fertilizers within the soil matrix, leveraging both plant and microbial processes.
