The xylanase purification was performed using ion exchange resin IR-120 EP and Sephadex G-75. The purified xylanase showed a total activity of 293.0 IU and a specific activity of 350.96 IU/mg protein and the enzyme was purified to 8.1 fold with 2.7% recovery. The purified xylanase was active over a wide spectrum of pHs from 3-10 and the highest activity was obtained at pH 7.0 followed by 74% of xylanase activity at pH 9.5. At pH 9.5, the xylanase exhibited its optimal activity at 70 °C indicating that the xylanase was alkaliphilic and thermophilic xylanase. The xylanase activity was greatly increased by FeSO4 and CuSO4 up to 332.15% and 194.1% respectively and slightly inhibited by CoCl2. Km and Vmax for the purified xylanase were determined at pH 9.5 and 70 °C for birchwood xylan as 22.13 mg/ml and 135.13 IU/min respectively. The crude and purified enzyme showed high specificity towards the xylans tested. The highest activity was observed for oat spelt xylan; it was three times the activity of birchwood xylan for the crude enzyme and more than six times for the purified enzyme. The specific activity of the xylanase towards birchwood xylan was lower than oat spelt xylan and avicell. The purified xylanase did not act towards carboxymethyl cellulose compared with the crude one.","PeriodicalId":48551,"journal":{"name":"Journal of Multidisciplinary Sciences","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89522416","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 trial was conducted under irrigated timely sown (ITS) and irrigated late sown (ILS) conditions. The genotypes were evaluated for yield and yield components, heading, maturity, disease reaction, etc. The effect of sowing time, location and genotype and their different interaction levels were significant for most of the traits. Wheat yield was significantly reduced in ILS condition as compared to the ITS condition. Regarding location, Dinajpur was better place for wheat production than other tested places. The mean value of the thousand-grain weight (TGW) of all genotypes was higher as compared to all check varieties. Out of eleven genotypes, ten produced a higher yield than BARI Gom 26, five produced a higher yield than BARI Gom 32. All the eleven genotypes were out yielded of the check variety BARI Gom 21. The highest yield (4099kg ha-1) was obtained in Dinajpur and the lowest yield (3108 kg ha-1) was obtained in Jamalpur. Genotypes, BAW 1290, BAW 1293, BAW 1317, BAW 1318 showed comparatively better performance in ILS condition representing that these advanced wheat lines were less affected by terminal heat stress under late sowing condition.","PeriodicalId":48551,"journal":{"name":"Journal of Multidisciplinary Sciences","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84132843","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 framework proposes a novel multi-layered architecture consisting of multi-agents capable of target detection, role allocation, and connectivity based on access to resources. Four different operations have been proposed namely mapping, searching, coordination and information fusion. Three different roles for the agents have been proposed namely mapper, searcher, and coordinator where mapper agent contributes in developing local maps, searcher agent explores the local map for target detection and coordinator agent is responsible for cluster coordination and communication among inter-cluster, intra-cluster and information fusion module. A novel concept of cell priority index (CPI) has been proposed to determine the level of damages and zone prioritization for a rescue operation. Two different novel indices namely role suitability index and role weighting index have been proposed for efficient allocation of roles among agents. The ad-hoc network model of the proposed system is evaluated for performance metrics under different mobility mechanisms in different propagation environments to suggest possible mobility approaches to be adopted for effective search and rescue mechanisms.","PeriodicalId":48551,"journal":{"name":"Journal of Multidisciplinary Sciences","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85470678","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}
