“…The compressor function is to compress and raise the air pressure and input fuel to the cycle. By defining the Isentropic efficiency for the compressor and also by determining the input temperature and pressure to the turbine, it is possible to calculate the temperature and pressure at the compressor output using the equations under temperature [10,20].…”

In the combined water-ammonia cycle, the double-ammonia mixture is used as the operating fluid. This cycle enables using resources such as waste energy, normal power cycle or an independent heat source that uses solar energy or global warming. Gas turbines have many uses, the most important of which is in the propulsion of various types of aircraft however, in industries, gas turbines are also used to operate mechanical devices such as pumps, compressors and small generators of electricity, and especially to provide peak loads and intermediate loads and sometimes basic loads [1]. Gas turbines are also increasingly used in combined power stations cycle. These power stations are made of a combination of vapor and gas turbines and there are several types of heat

“…Recently, different observational and randomized trials attempted to show advantages as well as limitations of surgical approaches for treating hyperthyroidism caused by the GD; however, there is a significant divergent in the spectra of treatment outcomes especially on longterm QOL requiring systematically assessment of the results. In total, a pertinent question now rises that whether the results from different studies are reliable in terms of the efficacy of surgical approach for improving patients' QOL [18][19][20].…”

Different observational studies and randomized trials attempted to show advantages as well as limitations of surgical approaches for improvement in patients' quality of life (QOL) suffering hyperthyroidism caused by the Graves´ disease (GD). We aimed to systematically examine the impact of surgery (thyroidectomy) on different components of QOL in patients with GD. Two reviewers began to deeply search the various databases of article published including Medline, Web of knowledge, Google Scholar, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library for all eligible studies in accordance with the considered keywords. In final, seven articles were eligible for the final analysis that published between 2012 and 2019. The Comprehensive Meta-Analysis Software was employed for analysis. Assessing the level of quality of life using SF-36 tool showed significantly increase in both physical component score (weighted mean differences of 0.428, p <0.001) and psychological component score (weighted mean differences of 0.277, p <0.001) postoperatively compared with the baseline values. The assessment of QOL using the Thy PRO questionnaire also showed significantly improvement in total QOL score after surgery compared with before that (weighted mean differences of -1.466, p <0.001). We revealed considerably improving both physical and mental aspects of QOL following surgery in Graves' disease.

“…In the era of computerization progress, chemical risk management must be coordinated through the efficient introduction of new procedures, along with the changing [ 2 , 3 , 4 ] manufacturing technologies. Broadly understood, information flow management is a challenge for modern enterprises, especially those integrating with the concept of Industry 4.0.…”

The features that are used in the classification process are acquired from sensor data on the production site (associated with toxic, physicochemical properties) and also a dataset associated with cybersecurity that may affect the above-mentioned risk. These are large datasets, so it is important to reduce them. The author’s motivation was to develop a method of assessing the dimensionality of features based on correlation measures and the discriminant power of features allowing for a more accurate reduction of their dimensions compared to the classical Kaiser criterion and assessment of scree plot. The method proved to be promising. The results obtained in the experiments demonstrate that the quality of classification after extraction is better than using classical criteria for estimating the number of components and features. Experiments were carried out for various extraction methods, demonstrating that the rotation of factors according to centroids of a class in this classification task gives the best risk assessment of chemical threats. The classification quality increased by about 7% compared to a model where feature extraction was not used and resulted in an improvement of 4% compared to the classical PCA method with the Kaiser criterion, with an evaluation of the scree plot. Furthermore, it has been shown that there is a certain subspace of cybersecurity features, which complemented with the features of the concentration of volatile substances, affects the risk assessment of chemical hazards. The identified cybersecurity factors are the number of packets lost, incorrect Logins, incorrect sensor responses, increased email spam, and excessive traffic in the computer network. To visualize the speed of classification in real-time, simulations were carried out for various systems used in Industry 4.0.
