The Relationship

A precision profile, the relationship between the concentration of a substance and its measured precision, is a convenient way of conveying the ability of an immunoassay to accurately measure the concentration of a substance in blood serum. A precision profile is characterized by the definition of precision. Historically, precision has been evaluated as the standard error of an estimator of the concentration in a sample conditional on the true concentration. In this paper, Bayesian predictive inference is used to develop a new measure of precision based on the accuracy with which an assay could infer the concentration in a hypothetical new sample. This leads to a natural procedure for evaluating a precision profile that avoids using approximations such as those inherent in traditional methods.

Automated Determination

Abstract A fully automated method has been developed for the determination of total cholesterol in blood serum, using the AutoAnalyzer system. According to the new method, based on the cholesterol determination of Abell et al. (1), the serum sample is saponified and subsequently extracted with carbon tetrachloride. After treatment with Liebermann-Burchard reagent, the amount of cholesterol is determined at 630 nm. The method can be used for free and esterified cholesterol because saponification is carried out. The relationship between the new method and that of Abell et al. is linear. The correlation coefficient is 0.98 and the standard error 1.5%. According to the new method, 30 samples can be analyzed per hour.

Cachexia is a multifactorial process of skeletal muscle and adipose tissue atrophy resulting in progressive weight loss. It is associated with poor quality of life, poor physical function, and poor prognosis in cancer patients. It involves multiple pathways: procachectic and proinflammatory signals from tumour cells, systemic inflammation in the host, and widespread metabolic changes (increased resting energy expenditure and alterations in metabolism of protein, fat, and carbohydrate). Whether it is primarily driven by the tumour or as a result of the host response to the tumour has yet to be fully elucidated. Cachexia is compounded by anorexia and the relationship between these two entities has not been clarified fully. Inconsistencies in the definition of cachexia have limited the epidemiological characterisation of the condition and there has been slow progress in identifying therapeutic agents and trialling them in the clinical setting. Understanding the complex interplay of tumour and host factors will uncover new therapeutic targets.

The article analyzes conceptual foundations, views and ideas concerning the essence of expert prevention. The relationship between the concepts of «prevention» and «prevention», which is in contact with each other, is investigated, because one of the main problems of the criminal investigation of the phenomenon of expert prevention is the ambiguity of both scientific understanding and the practical application of the corresponding conceptual-categorical apparatus. It is emphasized that the essence of expert prevention is the influence of the relevant subjects on crime through the use of special professional knowledge. That is, to the subject of forensic examination, should include studies of circumstances on the basis of which can be and should be developed scientific, organizational and technical measures of preventive nature. Proven that among the tasks of preventive nature, which can be solved by the staff of judicial-expert institutions, the development of aimed at forecasting in criminalistic aspects of circumstances contributing to the commission of crimes, taking into account the possibilities of certain types of expert research, should occupy an important place. It is proved that the preventive activities of forensic institutions of Ukraine should be carried out: in the production of examinations in specific criminal, administrative or civil cases; by summarizing expert, as well as forensic investigative practices; in the process of research on expert prevention; by providing on the basis of special knowledge of scientific and practical assistance to government agencies and public organizations in identifying circumstances conducive to the commission of crimes. In order to improve the quality of expert-preventive activities, the staff of the forensic institutions of Ukraine should pay maximum attention to the promotion of preventive activities among representatives of law enforcement and law enforcement agencies. On the basis of the analysis, the author’s definition of expert prevention is given: the activity of a forensic expert based on the laws and by-laws of normative legal acts, aimed at revealing the circumstances contributing to the commission of a crime, and the development of measures for their elimination with the use of special knowledge.

In this article, Kathleen Weiler reflects on the historiography of Country Schoolwomen, her recent study of women teachers in rural California. Using a broad definition of feminist research, Weiler summarizes some of the most salient issues currently under debate among feminist scholars. She raises questions about the nature of knowledge, the influence of language in the social construction of gender, and the importance of an awareness of subjectivity in the production of historical evidence. Using several cases from Country Schoolwomen, Weiler discusses the importance of considering the conditions under which testimony is given, both in terms of the dominant issues of the day — for example, the way womanliness or teaching is presented in the authoritative discourse — and the relationship between speaker and audience. She concludes that a feminist history that begins with a concern with the constructed quality of evidence moves uneasily between historical narrative and a self-conscious analysis of texts.

In a post-industrial world one of the foci of urbanism has been on the regeneration of former industrial sites along urban rivers. This is a contemporary urban design issue that needs further attention, especially in relation to urban forms and design interventions. This paper sets out to contribute to research in design by reviewing past theories and practices in order to inform the formation of conceptual ideas. These are of importance to inform practice and ensure responsive and responsible processes in planning and design. Such a review has hitherto been lacking, but with a renewed interest in urban densification, research in the design of cities is required. Thus, this paper provides a critical assessment of theories, which are identified and categorised in relation to urban riverside regeneration. For this study, urban design is considered as a craft requiring ‘savoir faire’ to ensure the functionality and quality of urban spaces. Transferable principles and ideas are identified in relation to the specific characteristics of riverside locations contributing to the definition of a ‘riverside urbanity’. It provides a theoretical framework identifying types of riverside landscapes, including the relationship between urban forms and river corridors.

The purpose of this work was to develop a criterion for estimating the quality factor of the tribosystem and to assess its effect on wear rate, friction coefficient and run-in time. The basis of the methodological approach when developing a criterion for the quality of the tribosystem is the parameters that take into account the construction of the tribosystem, the thermal diffusivity of materials and the loading conditions of the tribosystems.The definition of the quality of the tribosystem has been further developed, which, unlike the known one, takes into account the geometric dimensions and kinematic scheme of the tribosystem, the thermal diffusivity of materials and the rate of propagation of deformation in the surface layers of the triboelement materials during their contact interaction. Theoretical and experimental studies established the relationship between the quality value, wear rate and the friction coefficient in the process of running-in. It is shown that the increase in quality helps to reduce the above-mentioned parameters.The relationship between the running-in time and the quality value is established. It is shown that the process of running-in can be controlled. To reduce the running-in time, it is necessary to reduce the sliding speed during the transient process and to increase the tribological properties of the lubricating medium. The presented theoretical and experimental studies allow us to state that the quality of tribosystems Q can be a measure of the potential ability of the tribosystem to adapt (adapt) to operating conditions, providing the maximum resource.
