Modern society is increasingly dependent on the stability of a complex system of interdependent infrastructure sectors. It is imperative to build resilience of large-scale infrastructures like metro systems for addressing the threat of natural disasters and man-made attacks in urban areas. Analysis is needed to ensure that these systems are capable of withstanding and containing unexpected pert...

Heart valve replacements composed of living tissue that can adapt, repair, and grow with a patient would provide a more clinically beneficial option than current inert replacements. Bioartificial valves were produced by entrapping human dermal fibroblasts within a fibrin gel. Using a mold design that presents appropriate mechanical constraints to the cell-induced fibrin gel compaction, gross fi...

A method of lectin purification from carp roe (CCRA) was elaborated, which includes affinity chromatography on cross-linked ovomucoid and copolymers of polyvinyl alcohol and blood group-specific substances. That allowed obtaining lectin with electrophoretic purity and yielding of ˜ 42 mg÷kg roe. Electrophoresis in 15% polyacrylamide gel in the presence of β-mercaptoethanol showed one band with ...

The objective of this research is to compute the mechanical stresses in power transformer resulting from the currents more than rated value during its operation. Due to this high fault current, mechanical stresses are produced indifferent directions which may cause the damage of winding insulation. Various techniques have been adopted to analyze the stresses on transformer windings. For the acc...

The outstanding electrical, mechanical and chemical properties of graphene make it attractive for applications in flexible electronics. However, efforts to make transparent conducting films from graphene have been hampered by the lack of efficient methods for the synthesis, transfer and doping of graphene at the scale and quality required for applications. Here, we report the roll-to-roll produ...

The adhesion of spores of 3 Bacillus species with distinctive morphologies to stainless steel and borosilicate glass was studied using the fluid dynamic gauging technique. Marked differences were observed between different species of spores, and also between spores of the same species prepared under different sporulation conditions. Spores of the food-borne pathogen B. cereus were demonstrated ...

Concurrent evidence of some neurological manifestations in Alzheimer’s disease (AD) and corona virus diseases 2019 (COVID-19) has beaconed towards common links between these two global crises. Among numerous complications, the COVID-19 sufferers suffer from loss smell or anosmia. Similar experience been noticed AD patients. Thus, COVI-19 might have with respect to pathophysiology this co-mediat...

Graded properties, expressed by graded predicates, are ubiquitous in human discourse and reasoning. They are characterized by the fact that utterances of (simple) sentences involving them are graded, that is, admit mutual comparison. Typical examples are vague properties (such as red, old, tall, rich), i.e. those that do not establish a clear distinction between objects that satisfy them and th...

Adversarial examples are inputs to a machine learning system that result in an incorrect output from system. Attacks launched through this type of input can cause severe consequences: for example, the field image recognition, stop signal be misclassified as speed limit indication. However, adversarial also represent fuel flurry research directions different domains and applications. Here, we gi...
