The mean age of the participants was 28.29 ± 9.85 and 84% were uneducated. The majority of them work 8-10 hours per day. Daily average income from recyclables was found BDT 443.5 (US$ 5.15). In terms of health conditions, they were suffering mostly from digestive gastrointestinal issues, such as episodic diarrhea (39%), intestinal worms (57%), and hepatitis A (2.5%). The waste pickers’ living status was appalling, working conditions were hazardous. Yet, many were drawn to informal recycling due to the lack of alternatives. Therefore, special attention is required to enhance their health and working conditions as well as to integrate them into the city's formal SWM system. \u0000 ","PeriodicalId":8497,"journal":{"name":"Asian Journal of Applied Sciences","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84359563","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 development of new antibiotics is still slow in the face of growing needs. In addition, the overuse of antibiotics in developing countries has exacerbated the problem. Therefore, the development of new and multidimensional strategies is necessary to address this global problem. One of the solutions that has been considered by researchers in recent years is the development of targeted drug delivery systems based on magnetic nanoparticles. Unique magnetic properties the physicochemical and physiological properties of magnetic nanoparticles have made them useful as carriers for delivering drugs to the target tissue. In this study, we try to provide a general study to some subjects such as synthesis of magnetic nanoparticles and coating of these nanoparticles with natural polymer to grain (mucilage to grain) as a biocompatible, non-toxic and oral polymeric agent for maximum loading of ciprofloxacin antibiotic on nanostructured nuclei Magnetite and shell to mucilage to grain, to study the effect of different parameters and fabrication conditions of samples on the structural, physicochemical, magnetic, colloidal stability and antibacterial properties of samples, and also to investigate the effect of pH on ciprofloxacin adsorption on magnet nanoparticles by mucilage to the grain and release of the drug from these nanoparticles.","PeriodicalId":8497,"journal":{"name":"Asian Journal of Applied Sciences","volume":"584 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77081057","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 calibration of the force transducers, polynomial equations which correlate, the applied load on the transducer and its corresponding output signal in mV/V are deduced. These equations contain numerical constants A, B and C. This paper introduces a mechanism to determine the suitable number of significant digits for these constants.

Data was gathered through survey of 230 rice farmers and supplemented by key informant interviews in 24 rice-producing municipalities of the province. Results showed that RCH was adopted by farmers with higher level of education, higher income, larger farm holdings and with irrigated farms situated in the lowlands. About 90 percent of rice farmers in the area are already using RCH and adoption was considered permanent since all adopters did not revert to traditional practice after initially using the technology. The remaining non-mechanized farms are the rain-fed areas with poor road access, terraced small plots and waterlogged farms that deter the use of heavy machines. The respondents cited reduction of harvesting-threshing time which averts the exposure of farmers to climate risks brought by tropical cyclones and reduction of harvesting-threshing costs and postproduction losses as primary reasons for adoption of RCH. Empirical estimates using Logistic Regression revealed that RCH adoption increases with farm size and educational attainment. Topography is also an important determinant of adoption as farms situated in the lowland are more likely to adopt RCH than in the upland areas. With these findings, it is recommended that drivers and barriers of RCH adoption RCH be considered in the technology promotion.","PeriodicalId":8497,"journal":{"name":"Asian Journal of Applied Sciences","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88832545","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 method involves sampling 500 kg of waste on all collected waste. Two types of sorting are carried out. Sorting by size (<10 m, 20-100 mm >100 mm) and sorting by category (13 categories). Since waste varies according to its source, samples are made up of two types: market waste and household waste. The results indicate that the fine and extra fine fractions are the majority with 54.45% in the rainy season and 56.57% in the dry season.

Energy structure theory presents the basic equation as energy structure equation has been developed to study physical processes considering effects of the second law of thermodynamics directly. Energy components are used as basis of the energy structure equation. In this paper, to investigate the energy conservation principle using the energy structure equation, the variation of the energy structure equation is studied in different paths for the same amount energy applying to the system. In fact, a quasi-static path is used as a reference path, and other paths are studied using this reference when the same amount of energy is applied to the system in different conditions. Using this approach, in fact, energy conservation principle is applied to the energy structure equation, and therefore, the resultant relation has the first and second laws of thermodynamics as its basis together that has been developed in one relation. Therefore, the extracted relation will be a bidirectional relation that means all processes must satisfy this relation and vice versa.","PeriodicalId":8497,"journal":{"name":"Asian Journal of Applied Sciences","volume":"71 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77751072","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}
