The trend of improving the quality of products in the field of energy is aimed, in particular, at improving the quality of validation and verification of the declared parameters (strength of industry and research nuclear reactors and other pressure vessels, etc.). For verification of the parameters of the integrity and strength within the plant and operational tests and control the operating parameters using high-quality measurement and control equipment, which is part of the measuring channel. Improving the quality of the information is obtained, in particular, during full-scale tests using strain gauges, leads to an increase in the quality of products in general. The measurement result depends on many factors, which are not always possible to control due to technical and economic reasons. Using the apparatus of mathematical analysis and the theory of elasticity, it is shown that one of the parameters – the configuration of the strain gauge can reduce the uncertainty of the results of measurements by tensometric methods.

The dynamic control of atmosphere is an important factor for guaranteeing the quality of climacteric products during transportation. As atmosphere changes, respiration climacteric products would rot because of overripeness, thus leading to loss. Moreover, climacteric products must be ripened artificially when delivered to the destination, thereby causing economic waste. In this study, a new transportation method based on dynamic control of ripening environment was designed.The ripeness control method based on the dynamic control of ripening atmosphere was presented to accomplish quality safety during transportation as well as avoid a subsequent extra process of ripening. The transportation method was employed to stem from the ethylene’s ripening effect on climacteric fruits and vegetables. The ethylene generator and air circulation unit, which dynamically regulate and control the dual regional atmosphere of carriages during transportation, were quantitatively controlled by the central treatment layer. Ripeness level could be regulated by controlling the temperatures and time of exogenous ethylene release, to control the quality of products and ripen them. The proposed method was proven feasible through experiments. Results demonstrate that a volume fraction of 0.01% exogenous ethylene allows bananas’ respiratory intensity to reach the peak early; meanwhile, moderate low temperature (16 °C) can enable ethylene peak to appear in advance. Therefore, bananas’ ripeness can be controlled by changing temperatures and the ripening environment when transporting. This study can provide references for the control of products’ ripeness during transportation.

The system method of hierarchical decomposition and subsequent composition is widely used in practice. However, decomposition does not simplify, but even complicates the analysis of quality, since it is necessary to investigate, in addition to the object itself, all the selected subsystems and elements, which as integral patterns are characterized by their properties and connections. To ensure the required quality of products, it is necessary to consider and control not only the properties of the result (element, subsystem, product), but also all processes that form quality characteristics.

In this paper, we consider the control of animal carcasses and the detection of such a disease as scrapie. For our country, this animal disease remains quite rare, but at the same time it should not be overlooked. This is due to the fact that there are regular purchases of breeding cattle from abroad, and this is a risk of importing an infected animal. The relevance of the work is that the disease of sheep and goats-scrapie can not be detected at very early stages of its development. Symptomatic manifestations do not appear immediately, there are no clear clinical characteristics, which is why this disease can not be diagnosed for a long time. To assess the health status and predict the quality of products obtained, new approaches are needed to study the products of sheep and goat slaughter. Great importance is given to standard methods of studying, identifying certain patterns in clinical, anamnestic, morphological, metric and anatomical indicators of the animal body. Using these indicators and changing their dynamic characteristics, it is possible to make significant adjustments in the definition of this disease, which would allow us to develop a number of rules for modern veterinary and sanitary evaluation of animal slaughter products.

Accuride Corp. runs an aggressive research and development program at its Corporate Engineering Center in Henderson, Kentucky. Accuride engineers at this facility test and analyze contemporary designs, and conduct tests to verify the quality of products coming off the production lines. Some of the work involves accelerated fatigue testing in which wheels are subjected to very high loads for extended periods of time to determine where fatigue cracks might start and how they would propagate. Loaded and ready, an Accuride wheel has sensors in place for a test run. Information from the sensors is transmitted to a stationary receiver in the cab of the truck. One approach that Accuride employed to collect data from wheel strain gauges was to mount a data acquisition device directly to the wheel. This device obviated the need to transmit the data from the rotating wheel to a stationary receiver. Digital rotor telemetry offers several advantages for the testing team at Accuride Corp. Because the data are digitized before transmission, they are virtually immune to electrical noise. This means the signal is much clearer and cleaner than an analog system.

Poor Working Condition

The construction industry is vital to the economic development of any country. It has a major role in providing built infrastructures in an innovative and cost-effective way using an effective procurement approach. In contrast, the most widely used procurement method in Nigeria is the traditional procurement approach which is known for plaguing the industry with the poor working condition and poor performances thus, reducing the sustainability and quality of products and services. For this reason, there is a need for a procurement approach which utilises expertise to minimise the risk of non-performance and create a win-win environment for both client and contractors, while increasing transparency and add value to the project such like, the Best Value Procurement. Against the background, this paper aims to establish the perception of the Nigerian construction professionals on the unique factors of the Best Value Procurement. The paper outlines the following objectives: To identify the unique factors of the Best Value Procurement and, to establish the perception of the Nigerian construction professionals on the Best Value Procurement unique factors. Using a questionnaire survey, data was collected form 314 construction professionals involving Quantity Surveyors, Architects, Builders and Civil Engineers. Kruskal Wallis Test and mean score ranking was used for data analysis. The findings show that the professionals generally agree that the Best Value Procurement unique factors can bring about transparency, accountability, increase project performance and the contractor is the best to control risk and adds value to the project. This paper derives its significance from the need to stabilise the procurement system in Nigeria by transferring the risk and control to contractors who must act in the best interest of the client.

Abstract The aim of the study was to indicate the reasons for non-compliance of aluminium rim castings and, using quality management instruments (Pareto-Lorenzo diagram and 5WHy method?), elimination or reduction of non-compliant products. The object of the research was an aluminium rim, while the diagnostic process of the object of the research was based on the quality control of the chemical composition of the casting, the control of mechanical properties and the control of the continuity of the material structure by radiographic and microscopic methods. On the basis of the research carried out, it was found that a sensitive casting area is the front edge of the rim rim - a significant number of porosity clusters were identified in this area. The reason for their occurrence was also specified - too rapid flooding of moulds, which resulted in gassing of the alloy. The identified cause had its origins in human resources mismanagement, namely the lack of training of the newly recruited employee. So far, the company has not carried out analyses of quality problems with the use of a sequential quality management methodology, so the implemented corrective actions have not always led to the full achievement of quality objectives. The presented sequential method, which is a combination of diagnostic and control tests and quality management instruments, is a universal way to monitor the level of quality of products and to quickly correct nonconformities.

Starch is an integral part of grain of cereal crops (including barley), its content and properties significantly affect the processing and quality of products. One of the methods for increasing the variation in starch and amylose contents in starch is chemical mutagenesis. Chemical mutagens provide the possibility to obtain new allelic variations whose genes are involved in starch biosynthesis. In order to create mutant populations of barley, we used in our study the chemical mutagen phosphemide with solution concentrations of 0.002% and 0.01%. Three mutant generations (M1, M2, M3) were grown from the seeds of two barley samples (Zernogradsky 813, k-30453, Russia, var. Erectum; Dz02-129, k-22934, Ethiopia var. Nigripallidum) from the world collection of the N.I. Vavilov All-Russian Institute of Genetic Resources, after treatment with a mutagen in the field, and evaluated by a complex of selection traits. The starch content A and B and amylose content in starch were determined in the grain of the mutant and control populations of the second (M2) and third (M3) generations. The application of mutagen led to a significant decrease in the mass fraction of amylose in the starch of the studied samples in the second (M2) mutant generation. In the third (M3) generation, the inhibitory effect was preserved only in the sample Dz02-129. In the grain of the Zernogradsky 813 cultivar in M3, the starch and amylose contents in starch were above the control. The selection of forms with the elevated content of amylose, which have potential value for the processing industry, is advisable to carry out, starting with M3.
