It is commonly growing in tropical and subtropical regions now and is one of the most important plant resources as cuisine materials. Antioxidative activity of tamarind seeds was investigated. An ethanol extract prepared from the seed coat contained antioxidative activity as measured by the thiocyanate and thiobarbituric acid (TBA) method. Essential oils are highly odorous droplets found in minimal quantities in the flowers, stems, leaves, roots and barks of aromatic plants. They are not recognized as true oils as the vegetable oils, but highly fluid and volatile. Experts recognize an essential oil by its aroma and test the oil characteristics such as vaporization and crystallization point using Differential Scanning Calorimetry (DSC). DSC has emerged as a powerful experimental technique for determining thermodynamic properties of biomacromolecules. Volatile components of tamarind leaves and seed locally grown will be isolated by Microwave Assisted Extraction (MAE). The presence of essential oil as the volatile components will be investigated to determine whether this method is effective or not to extract the oil from tamarind leaves and seed. The parameters that will be measured are the time for the oil droplets formation and the optimum temperature for the extraction of oil. At the end of the extraction, amber color oil was obtained. Results showed that the time for the oil droplets formation increasing with the increasing weight of sample for both tamarind leaves and seed samples. The optimum temperature for the extraction obtained was 125ºC with the yield of 1.2 mL of seed oil. The vaporization and crystallization point of oil are presented in the DSC curve and the specific heat capacity of the oil are calculated.","PeriodicalId":314179,"journal":{"name":"Journal of Wastes and Biomass Management","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131787776","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}

With this point of view, this study was undertaken to determine the effectiveness of mulching from previous crop relative to herbicides and hand weeding on weed control and grain yield of rice transplanted in non-puddled soil after mustard in the northern Bangladesh during January to May in 2014 and 2015. Rice cv. BRRI dhan28 was transplanted with a combination of six weed control practices [Conventional tillage (CT)+3 hand weeding (HW) (Control); Glyphosate (Gly)+strip tillage (ST)+1HW; Gly+ST+pre-emergence (PE) herbicide (pendimethalin); Gly+ST+post-emergence (PO) herbicide (Ethoxysulfuron-ethyl); Gly+ST+PE+PO; and Gly+ST+weed-free (WF)], and two levels mulch of previous mustard [M0: no mulch and M50: 50% mulch (875 kg ha-1). Over the two years, CT produced 30% higher weed density and 40% higher weed biomass than ST. Spraying herbicides at PE followed by at PO in ST reduced weed density by 45% and weed biomass by 70%. Retention of 50% mulch reduced weed density by 20% and biomass by 34%. The combination of applied glyphosate, ST, followed by sequential application of PE and PO herbicides and the retention of 50% mulch achieved the highest weed control efficacy. Furthermore, this practice produced the 12% higher yield and 47% higher economic returns relative to manual weed control in conventional tillage. These results demonstrate the value of mulch integrated with pre-plant, PE and PO herbicides in controlling weeds and improving grain yield and return of rice transplanted in a non-puddled soil.","PeriodicalId":314179,"journal":{"name":"Journal of Wastes and Biomass Management","volume":"22 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114357615","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}

Polylactic acid (PLA) is known as a biodegradable polymer and it can be a potential \u0000substitute for the petroleum-based plastics. However, PLA is known to be brittle and it has a slow degradation rate. \u0000Therefore, the aim of this study is to modify PLA in order to overcome the limitations and broaden its application in \u0000the packaging industry. In the present study, PLA is incorporated with different fillers (starch and nanocellulose) \u0000and plasticized with epoxidized palm oil (EPO) to further improve its properties and increase the degradation rate. \u0000Solvent casting method is used for the preparation of the composites. The samples prepared were subjected to a soil \u0000test for six months. Mechanical properties of the composites were evaluated by tensile testing. The weight loss of \u0000composites were recorded monthly and the composites blends undergo characterization analysis using Scanning \u0000Electron Microscopy (SEM). The utilization of polymer blend composites is the most suitable alternative to improve \u0000the properties of PLA to be used in various applications. After further analysis it can be concluded that starch acts \u0000as a better filler compared to nanocellulose with the presence of EPO in the composites.","PeriodicalId":314179,"journal":{"name":"Journal of Wastes and Biomass Management","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122547708","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}
