Biosorption of Cu<sup>+ 2</sup> involves the functional groups –CO, –OH, and N–H of <i>U. fasciata</i> biomass. Various parameters were estimated using Response Surface Methodology (RSM), including pH (4–6), initial Cu<sup>+ 2</sup> concentration (60–140 mg L<sup>− 1</sup>), biomass dosage (0.08–0.40 g L<sup>− 1</sup>) and temperature (20–40 °C).

In order to analyze the equilibrium data, applied Langmuir, Freundlich, Langmuir-Friendly (L-R), and Redlich-Peterson (L-R) isotherm models. The multiple mechanisms were involved in the removal of Cu<sup>+ 2</sup> including chelation, ion-exchange and adsorption on <i>UF</i> biomass.

With changing seismic conditions of the tectonic plates, it has become important to design each structure in a way it can withstand various earthquake conditions. Although, flexibility of soil material offers good seismic stability to the structures but stability of earthen structures depends largely on geometry, material properties and different conditions it has to bear during its design life. An earthen dam designed keeping all these aspects in mind, is a cost-efficient method of retaining water. This work is centered around the analysis of slope stability of a section of Durgawati Earthen Dam built in Kaimur district of Bihar. The study takes into concern the behavior of slope of the earthen dam under different drawdown conditions along with seismic conditions developed. Various methods have been developed for slope stability analysis but all have some or the other limitations. Thus, the exact behavior of the dam in real-time is not predictable. Here, a comparative analysis of conventional method and finite element method has been run. In the study, it has been found that the difference in conventional and finite element method can reach upto 40%. The change of factor of safety (FOS) in different situations gives us an overview of the crucial phase in dam’s design life.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 1","pages":"45 - 49"},"PeriodicalIF":1.2,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The safety, potency and efficacy of herbal drugs depend upon the use of standardized crude raw drugs. Present study serves as baseline information for herbal drug regulatory authorities to have strict guidelines on the sale of crude drugs and also the need for implementation of Good Agricultural and Collection Practices (GACP). In the present study, 295 market samples of 102 crude drugs were studied for quality standards and genuineness. It was found that 17% of the crude market samples were adulterated and 83% were botanically correct species, as these complied with diagnostic macro-microscopical characters of authentic crude drugs. However, the qualitative analysis indicated that the foreign matter, total ash, acid insoluble ash, and water soluble extractive values of these market samples deviated from authentic samples by 5% to > 15%, indicating thereby that samples collected from market may differ in collection time, storage practices like drying process, storage, time /season of collection and geography which may affect its pharmaceutical quality.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 6","pages":"705 - 711"},"PeriodicalIF":1.2,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reported causal organism of tea dieback disease needed to be characterized by screening available variants population-wide since the level of virulence and host specificity depends on their genetic background. Estimating genetic diversity and determining the phylogenetic structure of <i>F. solani</i> isolates from tea plants can provide valuable insights into the pathogen, potentially assisting in the long-term management of dieback issues within the Indian tea industry.
