Nowadays, non-metallic heterogeneous materials are widely used in mechanical engineering, which is primarily due to their unique properties, such as strength, light weight, corrosion resistance, and high vibration, sound, heat insulation characteristics. At the same time, non-destructive control methods that would allow obtain most complete picture of defective state products made great importa...

Atopic dermatitis is a chronic inflammatory skin disease associated with cutaneous hyperreactivity to environmental triggers and is often the first step in the atopic march that results in asthma and allergic rhinitis. The clinical phenotype that characterizes atopic dermatitis is the product of interactions between susceptibility genes, the environment, defective skin barrier function, and imm...

The RecQ family of DNA helicases has members in all organisms analysed. In humans, defects in three family members are associated with disease conditions: BLM is defective in Bloom's syndrome, WRN in Werner's syndrome and RTS in Rothmund-Thomson syndrome. In each case, cells from affected individuals show inherent genomic instability. The focus of our work is the Bloom's syndrome gene and its p...

Protein functionalization constitutes a particularly interesting target for biopharmaceutical applications, which increasingly relies on monodisperse proteinpolymer conjugates having controllable therapeutic properties.[1,2] Proteins modified with precisely controlled polymeric materials have the potential to exhibit a wide range of improved biological effects.[3] Linear polymers have been stud...

The healing of graphene grown from a metallic substrate is investigated using tight-binding Monte Carlo simulations. At temperatures (ranging from 1000 to 2500 K), an isolated graphene sheet can anneal a large number of defects suggesting that their healings are thermally activated. We show that in the presence of a nickel substrate we obtain a perfect graphene layer. The nickel-carbon chemical...

The purpose of this study was to improve the diagnostics efficiency modern diesel engine injectors with electronic controls. Experimental studies, performed using certified specialized equipment injectors' manufacturers and standard software packages for data analysis, made it possible prove adequacy theoretical research get results that are more accurate. Those contribute development a product...

This study aims to determine the value of sigma before improvement is carried out and find causes defects in production process, as well produce proposals for quality control products. The population this was Arsel furniture table products during April 2015 March 2016 which amounted 420 Sampling using purposive sampling techniques with considerations used, number samples used 306 samples. resul...

The main objective of this study is to show how the use more than ± 3? in formulas determine limits variables statistical process control charts affects quality manufactured products and, consequently, final consumer. In research process, induction and description methods were used required values parameters, constants others used, which allow showing proposed objective. results indicate that b...

General inspector errors may consist of accepting defective units of product or rejecting good units of product. It can be said that the human element in the inspection process is the inspector himself, who contributes to inspection errors. Besides some other errors like use of wrong spesifications, wrong measuring instrument, improper filling of documents etc., in some cases the effects of ins...
