“…Given that the key emphasis of the innovation rests on the mechanism to remove the medical gloves from the hand without contact, the computational structural analysis scrutinized the structural integrity of the remover design. FEA stands as a widely recognized numerical technique extensively employed to investigate challenges linked to mathematical modelling across the domains of science and technology [10][11][12][13][14]. The geometrical model of the glove remover design was exported into ABAQUS, an FEA software, in the ACIS file format (.sat).…”

Medical gloves play a pivotal role in ensuring clinical and hospital safety, as well as optimizing performance. Throughout the medical field, it has been traditionally understood that medical gloves function as a vital barrier, safeguarding both healthcare providers and patients, thereby diminishing the transmission of infections. Presently, healthcare personnel take off their medical gloves manually, using their hands, before discarding them. Should healthcare workers not diligently follow post-precautionary practices, including thorough handwashing and sanitization, the potential for infection increases significantly. Consequently, it is imperative for this study to explore methodologies for the proper removal of used medical gloves from hands, eliminating the need for direct contact prior to disposal. The primary goal of this study was to design and analyse a removal tool for used medical gloves tailored to minimize the risk of infection. Primary and secondary data were procured through the utilization of observation, interviews, and scholarly journal articles. This was succeeded by a progressive sequence involving the evolution of design concepts, the creation of three-dimensional models, rigorous analytical procedures, and comprehensive assessments of usability. The results of our investigation indicate that the suggested configuration of the medical gloves remover is deemed acceptable with regard to its incorporated features, including the adaptable gloves remover structure, main housing, front panel, disposal bin, and bracket for attachment. However, potential refinements may be requisite to amplify the design’s overall efficacy in facilitating the touchless removal of used medical gloves.

“…In dental implantology, finite element analysis (FEA) stands out as an extensively used computational technique. It empowers researchers to predict outcomes that can be challenging to ascertain through in vitro and in vivo studies, especially at the interface between bone and implant [12][13][14]. FEA plays a pivotal role in addressing mathematical modelling challenges across various scientific and industrial domains, spanning analyses like structural, vibration [15], manufacturing [16], fatigue, fluid [17][18][19], fracture mechanics, and thermal [20].…”

The robustness of dental implant systems in the context of occlusal restoration relies significantly on biomechanical factors associated with the imposition of excessive loads. These factors encompass the macro geometries of the implants, bone qualities, parafunctional oral habits, and specific materials employed. The choice of different implant lengths in different bone qualities may give rise to distinct effects on the way loads are distributed across the interface between the implant and the adjacent bone. As of now, the influence of implant length and bone quality on the surrounding tissues and the stability of implant structure continues to be a matter of debate and uncertainty, particularly in situations involving the possibility of implant failure. This study employed three-dimensional finite element analysis to investigate five distinct implant lengths (4, 6, 10, 13, and 15 mm) in two types of bone quality (type II and III). The bone tissues were characterized through the utilization of computed tomography image datasets and then underwent processing within the SolidWorks software. All geometric configurations were transformed into finite element models, which were subjected to analysis within the ANSYS software. Anisotropic and isotropic properties were attributed to the bone and implant models, respectively. A dynamic occlusal loading quantified at 300 N was applied to the implant body, accompanied by a pre-tension force of 20 N on the screw component. The longer implants exhibited decreased stress magnitudes in type II bone (87.86 – 36.66 MPa) and increased stress magnitudes in type III bone (80.5 – 2128.9 MPa) within the surrounding bone tissue, in comparison to the shorter implants. However, stress within the implant body was generally elevated with the use of longer implants in both bone types (type II: 505.32 – 625.35 MPa; type III: 500.45 – 2186.7 MPa). Irrespective of bone quality, the longer implants predominantly led to lower bone strain levels (type II: 0.006828 – 0.003328; type III: 0.054250 – 0.021678) and overall deformation of the implant-abutment assembly (type II: 0.1458 – 0.1348 μm; type III: 0.1754 – 0.1492 μm) compared to their shorter counterparts. Among all the assessed findings, type III bone displayed a more pronounced adverse impact on the biomechanical responses of the dental implant and neighbouring bone except for the implant stresses under the applied physiological loading.

The demand for increased performance both in the professional and amateur sectors and the inclusion of the bicycle in the city as a clean, silent, inexpensive, and healthy personal transport, is responsible for the technological growth of the industry. This study aims to analyze the effect of the design parameters on the bicycle crank arm and to find the best design value within the range for minimal defects. The strength of the structure design is significant to ensure the performance of the bicycle crank arms. To solve this problem, several design structures and parameters were studied. The selected parameters in this study are crank arm length, width, thickness, number of cranks spider, and rib design. Von-misses stress, strain, and displacement are selected as dependent variables. Aluminium Alloy 6061-T6 is the selected material in this study. The external load of 1000 N force was applied in the y-direction. The length analysis results show that 160 mm length, 30 mm width, and 10 mm thickness with five crank spiders and pocket design arm have the lowest stress, strain, and displacement. By bringing a new alternative to the crank's arm structure, the cost of the manufacture will be reduced. At the same time, it can help precisely improve the rigidity of producing complex 3D shapes.
