It creates various kinds of products like cages, souvenirs, kitchen appliances, ashtrays, ship joint shafts, hotplates, fitness equipment, manual water pumps, pendulum scales, garden benches, lamp posts, interior lights, wall lamps, grills, manhole, and other types of equipment to deal with workplace safety. However, some workers ignore the various potential hazards during the production process. They are more concerned with comfort aspects than safety. This research enhances occupational safety and health (OSH) aspects through Hazard Identification Risk Assessment Risk Control (HIRARC). It is done by identifying potential hazards in the workplace and making a hazard risk assessment to determine appropriate controls for reducing the hazard risks. Based on hazard identification and risk assessment, the results show 11 high, 2 medium-risk, and 1 low-risk levels. The risk control proposals are in the form of training on the importance of OSH among employees/workers. It also raises awareness to provide work safety facilities and establish policies related to OSH.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86027897","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 omission of infill wall is for commercial purposes and parking of vehicles in ground floor. In this study, study on the behavior of the structure is done when a soft story happens in different floor levels. A building explained as per NBC 201 and NBC 205 is taken into consideration. Soft story is assigned in all floors to study the responses separately. An equivalent diagonal strut is assigned to the structure to account the consideration of infill wall. Non-linear hinges are assigned to structural members. Different parametric study is performed in terms of displacement, story drift, time period, formation of hinges, performance point, and capacity curve to compare the behavior of the structure. Linear static and non-linear static (Pushover analysis) analysis is performed to evaluate 4 different models. Modal analysis is performed to obtain time period of different models. The time period of bare frame, ground floor soft story, first floor soft story and second floor soft story using modal analysis is 0.65, 0.49, 0.47 and 0.29 respectively. Pushover analysis is performed to obtain pushover curve of different models forming different non-linear hinges in multiple steps of analysis. Step 1, 4, 7 and 10 were analyzed and hinges from basic to collapse prevention has formed. Story drift of bare frame of all story has been compared to the story drift of buildings having soft story in ground, first and second floor. Comparing variation of story drift for ground, first and second floor between bare frame and ground floor soft story model, the values show 13%, 82% and 85%.

As the factory's primary input, Sugar Cane cannot supply 8000 TCD Factory Capacity, so 6000 TCD is chosen as an alternative. After commissioning, a lack of steam for servicing the process occurred because the Turbine at full load required 7,6 Kg/kWh. Desuperheater supports the additional steam for the process, which is only 20 TPH. Meanwhile, the steam from the turbine supplies 84 TPH. The need for 32 TPH must be solved, and a specific strategy should be prepared. The Applied Thermodynamics Re-Engineering is a potential method that can be applied in which the findings show that the deficit of 32 TPH steam for the process can be solved precisely.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85950283","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 study aimed at evaluating the effectiveness of different drying methods on antioxidant activity and phytochemical availability in leaf ethanolic extracts of Costus speciosus, Coccinia grandis, and Gymnema sylvestre. Plant leaves of the selected species were subjected to shade drying at room temperature (25 + 5℃), oven drying at 45 ℃ and freeze-drying methods. The extracts were obtained by a maceration method with 95% ethanol. Obtained ethanolic extracts were analyzed for antioxidant activity in terms of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, total reducing power and total antioxidant capacity. Phytochemical availability was determined qualitatively and quantitatively in the extracts. All the plant species and drying methods had a significant difference (p<0.05) for the tested antioxidant activities. Among the drying techniques, the freeze-drying method was more effective to preserve the antioxidant compounds and phytochemicals compared to oven drying and shade drying. The lowest antioxidant activity and phytochemical availability were shown by the leaves subjected to oven drying at 45 ℃. The freeze-dried leaves of C. speciosus ethanolic extract demonstrated the best radical scavenging activity for DPPH and ABTS assays with IC50 values of 57.27 + 2.08 μg/ml, 21.86+ 3.55 μg/ml respectively. Furthermore, the highest content of total phenolics (82.88+2.31 mg GAE/g), tannins (9.58 +2.71mg TAE/ g), terpenoids (45.10+3.46 %), and alkaloids (19.37+3.54%) were recorded in C. speciosus among all dried leaves from the selected species. It can be concluded that the freeze-dried leaves of all plant species showed a higher value of antioxidant activity and phytochemical availability and that can be potentially used for the production of pharmaceuticals and novel functional foods.","PeriodicalId":8524,"journal":{"name":"Asian Journal of Engineering and Applied Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76767777","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}
