The characterization of synthesized compound has been done on the basis of elemental analysis, spectral studies (FTIR,1HNMR, Mass) and surface morphology by Scanning Electron Microscopic (SEM). The structural composition of synthesized compound has been determined by X-Ray diffraction (XRD). The inhibition property of Schiff base 3,4,5-trihydroxy –N-(3,4dimethoxy benzylidene) benzo hydrazide on the corrosion of aluminum in 0.5N HCl,1NHCl, 2N HCl were studied using weight loss technique and electrochemical studies revealed mechanistic aspects of corrosion inhibition like potentiodynamic polarization measurements indicated the nature of inhibitor is a mixed type and impedance studies supported the formation of a protective layer of inhibitor on a metal surface. Adsorption of the inhibition molecule on aluminium surface was consistent with the Langmuir isotherm.","PeriodicalId":20915,"journal":{"name":"Research Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139279757","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 physical parameters studied were air and water temperature, water depth and transparency, total solids (TS), total dissolved solids (TDS) and total suspended solids (TSS). Chemical parameters studied were pH, salinity, total alkalinity and dissolved inorganic phosphates. These were recorded from the day of culture till the harvest period at 30 days interval. Air and water temperature were increased from the day of culture till the harvest period. Transparency of the water used for the culture was high (40±0.1cm) during initial days and reduced thereafter. Water depth was increased from the day of culture till the harvest period. Suspended and total solids recorded were high on day 90 and total dissolved solids were high (20±1.2mg/l) on the day of culture and harvest. The level of pH recorded was high (8.3±0.0) on day 60 and the level of salinity and total alkalinity recorded was high on day 30. The dissolved inorganic phosphate level was high (1.0±0.0mg/l) on the day of culture which became reduced during the growth and harvest period of shrimp. The feed consumption and gain of body weight were also recorded on each 10 days interval. The body weight was increased as the day of culture was increased and it was positively correlated with the quantity of the feed consumed.","PeriodicalId":20915,"journal":{"name":"Research Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139279784","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}

Around 1% of people worldwide are affected by it, and women are 2-3 times more likely to be affected than males. Preclinical RA, genetic influences and environmental influences all have a role in the etiology of the illness. Since there is no recognized treatment for RA, achieving the lowest disease activity and, if possible, recovery remains the key goals of care. The literature on the various RA therapy options, their mechanisms of action, side effects and innovative drug delivery systems that are currently being used for medication administration are highlighted in this review, with non-steroidal anti-inflammatory drug delivery systems receiving the most attention. The most popular medications from each class are reviewed, including corticosteroids, non-steroidal anti-inflammatory medicines (NSAIDs), disease-modifying anti-rheumatic drugs (DMARDs) and biologics. Traditional medication therapy has various drawbacks, including inadequate bioavailability, first pass metabolism, gastrointestinal enzyme degradation, limited solubility and permeability, food interactions and toxicity. Innovative drug delivery technologies such as microspheres, nanoparticles, dendrimers, liposomes and others, hold great promise since they have been able to overcome the drawbacks of traditional drug delivery systems. The current review compares and contrasts numerous unique drug delivery methods that have been investigated for using anti-rheumatic medications, as well as the benefits of using these novel methods over traditional drug delivery methods.","PeriodicalId":20915,"journal":{"name":"Research Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139280130","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}

M. rosenbergii females were individually stocked for 120 days in three 1500L freshwater recirculation system tanks and fed a commercial diet. Ovarian development, molting and spawning events were checked daily. In addition a number of egg and larval quality parameters were determined. The breeding frequency, fecundity, egg laying success rate, egg dimensions and egg hatchability were not significantly different between animals from the four different sources. However, there were significant differences in terms of offspring quality between the different broodstock sources. Individual dry weight, larval development rate, time to reach the post-larval stage, post-larval survival and tolerance to ammonia toxicity were all better in offspring originating from all broods did not significantly differ in terms of breeding frequency, fecundity and egg dimensions. However, larval quality of Ganga riverine wild and Ganga riverine pond-reared breeders was markedly better than that of Gandak riverine wild reared stock and Gandak riverine pond-reared stock in terms of larval development, survival and post larval production. These results indicate that broodstock sourcing deserves proper attention in hatchery operations of M. rosenbergii. It furthermore proves that domesticated (pond-reared) animals are not necessarily inferior as breeders as compared to wild-sourced animals. The results may also point out the potential to selectively breed stocks with improved characteristics adapted to the local culture environment.","PeriodicalId":20915,"journal":{"name":"Research Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139280211","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}
