The use of adhesive joints is increasing in aerospace, aviation, automotive, construction and marine industry due to their easily applicable properties, low-costs and light weights compared to traditional jointing methods such as bolts, rivets, welding and soldering. Due to the high fatigue strength, resistance to seawater corrosion and light weigh...

The present analysis was aimed to identify the properties of Al 2024 composite reinforced with lithium and silicon nitride to make it applicable for automobiles, sports and aerospace applications. An effort was made to reduce the density and increase the hardness and impact properties of aluminum 2024 matrix with individual and multiple reinforceme...

BackgroundMissed vascular events, infections, and cancers account for ~75% of serious harms from diagnostic errors. Just 15 diseases from these “Big Three” categories account for nearly half of all serious misdiagnosis-related harms in malpractice claims. As part of a larger project estimating total US burden of serious misdiagnosis-related harms, ...

Seat frames in commercial vehicles generally consist of components such as foot brackets, seats, back, head restraints and fasteners. In addition to mechanical properties, comfort is another important parameter. This study aims to reduce the cost of a commercial vehicle by means of alternative materials and design changes in the passenger seat fram...

BackgroundPyoderma gangrenosum (PG) is a chronic, ulcerative neutrophilic dermatosis. PG presents a diagnostic challenge, largely due to the many mimicking diseases, the lack of confirmatory laboratory or biological markers, and the absence of widely accepted diagnostic criteria. In particular, PG is often mistaken for necrotizing soft tissue infec...

This article presents results of the study on the dependence of the structural-phase state of alloys based on Ti-12.52Al-43.08Nb system (wt.-%) on the temperature of spark plasma sintering. It has been established that spark plasma sintering of Ti-Al-Nb alloys under the temperature of 1500 °C resulted in melting the aluminum component of the mixtur...

In this paper, a new hybrid Taguchi salp swarm algorithm (HTSSA) has been developed to speed up the optimization processes of structural design problems in industry and to approach a global optimum solution. The design problem is posed for the shape optimization of a seat bracket with a mass objective function and a stress constraint. Objective fun...

BackgroundLaboratory tests are an essential aspect of current medical practice and their use has grown exponentially. Several studies however have demonstrated inappropriate use of laboratory testing. This inappropriateness can lead to delayed or wrong diagnosis, negatively impacting patient safety and an increase in health care expenditure. The ai...

Chitin and chitosan as green and active biomacromolecules were extracted from local seafood waste (shrimp shells). The extraction was carried out by a soft chemical process, followed by structural characterization (FTIR, XRD, viscosity average molecular weight M̅v), thermal stability by TGA, and antibacterial tests. FTIR and XRD spectra confirmed t...
