Analysis of a Support Base Stand using Finite Element Analysis

In this paper, deformation, Von-Mises stress, and failure analysis were carried out on a base stand using ANSYS workbench. The structural design was carried out using SolidWorks software and then imported into the ANSYS workbench for analysis. The investigation is performed using four different materials, i.e., structural steel, aluminum alloy, carbon fiber, and copper alloy, with an applied loading force of 1000 N at the tip of the structure. This technique highlights a complete reaction of the structure to the loading force, therefore providing room for structural optimization to reduce the risk of unexpected failure and unnecessary material wastage. The results obtained were compared and analyzed to identify the best material capable of withstanding the subjected force. Based on the Von-mises result, Carbon fiber has the highest possible maximum stress value of 4.70e+07 Pa, followed by structural steel, then Copper alloy. At the same time, the aluminium alloy has the least minimum Von-Mises. Structural steel is the very best option based upon the analysis outcomes. Its factor of safety is above unity in all the designs, which indicates that the structure has been over-designed. For that reason, it is suggested that the structure needs to be enhanced.

Histomorphological study of lead-induced lungs lesion of mice treated with Moringa oleifera leaves extracts

Background: Moringa oleifera leaves extracts are currently among the most common medicinal plants used to cure some diseases. Many studies have been conducted on the benefits of Moringa oleifera leaves extracts but only few studies focused on its Antifibrotic effects on lung tissue. Aim: To study the Histomorphological changes associated with Moringa oleifera Leave extracts on lead-induced lung lesion of Mice. Materials and Method: Twenty adult mice were divided into four groups, three test groups (A, B and C) and a control group (D). The test groups were administered orally with 5mg/kg lead acetate and 10mg/kg Moringa oleifera leaves extract concurrently; 5mg/kg lead acetate only; 10mg/kg Moringa oleifera leaves extract only; while the control group did not receive any intervention. The intervention period lasted for three weeks. On the twenty-two day of the research, the animals were sacrificed; lung tissues were harvested, processed for histological examination and stained using Hematoxylin and Eosin staining technique. Result: Group A animal administered with lead acetate and Moringa oleifera leaves extract concurrently, shows that the deleterious effects of Lead were ameliorated, with an improve histological features of the lungs when compared with that of the Group B. while an Ill defined alveoli, thinned alveoli wall, sacs emphysema and distortion of the parenchyma cells that constitute the lung tissue are seen in test Group B, administered with lead acetate only. A remarkable, intact lung alveoli, lung parenchyma cells were observed to in test Group C and very much correlated to that of the control group. Conclusion: Moringa oleifera administration reduced the severity of lead’s damaging effects to the lungs, and may likely exhibits anti-fibrotic as well as prophylactic effects by repairing damaged alveoli and in the latter case by preserving and /or regenerating the lung tubules.

Multi agent-based control architecture in intelligent transportation system with infrastructure-based sensing

Traffic congestion has negative impact in our life. In 2001, the European Commission estimated costs of congestion at around 120 billion Euro. The research of Intelligent Transportation System (ITS) becomes interesting since infrastructure expansion in not always feasible. In order to find out the impact of automated vehicle and intelligent infrastructure to traffic performance, we develop a model of hierarchical vehicle controller and intelligent infrastructure and implement them in a simulated environment using Multi Agent System concept. Several traffic scenarios are deployed to observe the effect of the designed vehicle controller and the model of intelligent infrastructure in traffic.MediamaticsElectrical Engineering, Mathematics and Computer Scienc

Institutional strengthening of farmer groups on sustainable intercropping in Majalengka Regency, West Java Province

The government implements a special effort program (of food self-sufficiency) to achieve national food sovereignty focusing on three commodities (rice, maize, and soybeans). One of the efforts is to increase production with the intercropping pattern (Turiman). The program sustainability must be supported by strong farmer institutions. This study aimed to obtain the information about the farmer groups institution as a strong capital for sustainable farming. This study used a qualitative approach with data related to the assessment problem. This study also used relevant literature to learn the correlation between empirical facts and government programs. The study was conducted in June 2019 in Babakan Village, Majalengka Sub District, Majalengka Regency, West Java Province on 100 respondents. Based on the results, the farmers were still oriented to the monoculture model (maize). The supporting organization as a transformation institution was still very weak as indicated by the organizational structure. The low farmer knowledge on the technology introduced and the farmer group management as a technology transfer agent were still oriented towards monopoly profits. Thus, the Turiman model can be come a consideration for its sustainability. Such conditions require government intervention to achieve the strength farmer group institutions with various appropriate methods, such as assistance in managing organizations and collecting business assets as well as business capital
