Abstract
BackgroundThere is increasing evidence that assessing outcomes in terms of capability provides information beyond that of health-related quality of life (HRQoL) for evaluation of outcomes in mental health research and clinical practice. Aims This paper aimed to assess similarities and differences in the measurement properties of the ICECAP-A and OxCAP-MH instruments in schizophrenic patients with depression, and compare these measurement properties to those of (i) EQ-5D-5L / EQ VAS instruments and (ii) mental health specific measures.Method Using data for 100 patients from the UK, measurement properties were compared using correlation analyses, Bland Altman plots and exploratory factor analysis (EFA). Responsiveness was assessed by defining groups who worsened, improved or remained unchanged, based on whether a clinically meaningful change in the instrument scores between baseline and 9-month follow-up assessments. ResultsThe two capability instruments had stronger convergent validity with each other (0.677) than with the HRQoL (0.354-0.431) or the mental health specific (0.481-0.718) instruments. The OxCAP-MH tended to have stronger correlations with mental health specific instruments than the ICECAP-A, while the ICECAP-A had slightly stronger correlation with the EQ VAS. Change scores of the capability instruments weakly correlated with change scores of the health-related HRQoL scales (0.131-0.269), but moderately with those of mental health specific instruments for the ICECAP-A (0.355-0.451) and moderately/strongly for the OxCAP-MH (0.437-0.557). ConclusionsAssessing outcomes in terms of capabilities for schizophrenic patients with depression provided more relevant, mental health specific information than the EQ-5D-5L or the EQ VAS. The ICECAP-A and the OxCAP-MH demonstrated similar psychometric properties, but the OxCAP-MH was more correlated with disease-specific instruments.

Objective. The aim of the study is to find rational ways to change the total energy consumption spent on cement production in terms of 1 m3 of concrete.Method. To obtain reliable data, experimental and laboratory methods for testing cement were used.Result. Tests have shown that at constant concrete strength, the consumption of cement per 1 m3 of concrete decreases with an increase in the specific surface of the binder, especially significantly in the case of Portland slag cement. The calculation results show that with an increase in the specific surface area of cements, the total energy consumption for their production, referred to 1 m3 of concrete of the same strength, decreases, and most significantly with an increase in the specific surface area of cements from 300 to 400 m2 /kg and less from 400 to 500 m2 /kg.Conclusion. To reduce the energy intensity of concrete, it is necessary to use cements ground much thinner than they are ground at cement plants in open-type mills, despite the increase in energy consumption. Cements with high fineness of grinding can reduce the cycle of heat and moisture treatment of concrete products. Reducing the cycle allows to increase the turnover of molds and labor productivity at precast concrete plants, as well as further reduce energy consumption for the production of prefabricated reinforced concrete structures.

Published: May 2022

Objective. The targets of modern construction require the search and development of new efficient technologies. The main trend in building architecture is the creation of spectacular (buildings-symbols, objects of competitions of countries) objects and structures that attract the attention of people and add to the list of unique attractions. To implement such projects, it is necessary to introduce high-tech advanced techniques, which is the electrostatic method of manufacturing fiberreinforced concrete.Method. The paper considers a new method of forming products and structures from fiber-reinforced concrete using electrostatics. An important place in the method is occupied by the physics of interfacial phenomena, namely wetting and capillary effects. The electrostatic deposition of layers of dry concrete mixture on the shaping frame occurs with the help of electrostatic sprayers.Result. This method allows saving cement, due to the use of a water-cement ratio close to the theoretical value. The issue of compaction of applied layers of dry concrete mix due to wetting with water with surface-active additives is discussed. In this regard, the kinetics of filling through and dead-end capillaries with water and other aspects of the new technology are considered. A hydrophilic binder has been developed using calcium lignosulfonate additive, which makes it possible to demonstrate the effectiveness of the electrostatic method in the future.Conclusion. The processes of wetting and the kinetics of liquid filling capillaries and channels of various shapes between the particles of the dry concrete mixture, as well as the compaction of the powder system as a result of moisture, will make it possible to realize difficult and unique projects in reality. The developed hydrophilic cement based on the surface-active additive LST (0.25%) contributes to the effect of interfacial electrostatic adhesion, thereby improving the properties of fiber-reinforced concrete.

Objective. Formulate the general principles for the construction and operation of an integrated electronic document management system, as well as list the possibilities of document management automation.Method. The article is based on methods of working with electronic documents, methods of searching, processing and storing information, methods of automating various office functions.Result. The potential advantages of electronic document management systems are identified, which are the improvement of documentary support for intra-organizational and external communications in order to improve the regulation and coordination of operational activities, mutual agreement and adjustment of management decisions.Conclusion. The widespread use of electronic document management systems will make it possible to distribute their functional content as an information environment for management, control and collective interaction. There are specifics of electronic documents, especially in terms of legal force, validity, storage methods, use of open forms and recording standards for the exchange of electronic documents. At the same time, the legal justification for certifying the authenticity of electronic documents using an electronic digital signature or using a system of contracts between participants in an electronic exchange is of great importance. Electronic documents have a physical and logical structure that do not coincide with previous ideas about a document as a rigid, unchanging structure of information and its carrier.

Objective. The purpose of the study is to illuminate the obtained experimental research data, measurement technique, as well as the design of a la-laboratory bench for full-scale tests of thermoelectric system (TES) for uneven cooling of electronic boards.Method. The article describes the experimental set-up and measurement procedure of laboratory thermoelectric system for electronic circuit boards cooling. The experimental stand is made on the basis of the measuring equipment of the laboratory of semiconductor thermoelectric devices and devices of Daghestan State Technical University.Result. We obtained plots of time dependences of temperature changes in thermoelectric system checkpoints at different thermoelectric battery (TEB) supply currents. Determined were the temperature dependences of the thermoelectric elements of the electronic board simulator at their non-uniform cooling on the parameters of FEB and working substance as well as the time variation of the temperature of the shell of the vessel with the working agent.Conclusion. As a result of full-scale tests of the device it was found that the use of a cooling system reduces the temperature of heat-generating elements to acceptable values. In particular, the temperature of heat sources decreases to 345 K and 344 K (from 428 K and 396 K) if the total heat-generating power of the electronic board is 120 W. At the same time, the temperature background created by the heat-generating elements in the nearby areas of the electronic board simulator also decreases. The discrepancy between the results of calculations carried out beforehand and the experiment was estimated to be 8%.

Published: May 2022

Objective. The article substantiates the need for digital simulation of emergency impact in the study of the stability of a building to progressive collapse by creating a simulator of local destruction.Method. To ensure the unique architectural appearance of the projected multifunctional high-rise complex, a complex shape has been developed with recesses in which elevator shafts are located. The principle of control of the structure due to the influx of external energy is observed. Energy conversion and the necessary protection is provided by the presence in the spatial frame of the building of balancing connections near architectural recesses, which allow stabilizing the state of a complex system. The spatial rigidity of the structural scheme of a high-rise building is ensured by the use of symmetrically located diaphragms and stiffening cores, rigid nodes for interfacing with the supporting structures of outrigger systems.Result. The calculation algorithm for progressive collapse includes the calculation of the stress-strain state of the building frame elements during normal operation. An analogue of the emergency action is created by excluding from the design model the bearing element, the instantaneous removal of which is modeled by a force with the opposite sign, determined by the results of the calculation in the normal operation stage.Conclusion. The stress-strain state of the frame, which occurs during local destruction, is a criterion for resistance to progressive collapse. The question of the need and the established form of outrigger floors in relation to a specific building has been investigated. The dependence of the dynamic characteristics when changing the structural solutions of the frame of a unique building is given.

Published: May 2022

Objective. The purpose of this work is to develop a methodology for an objective assessment of the environmental safety of construction sites and development areas.Method. The study is based on a conceptual approach to assessing the environmental safety of construction sites and territories.Result. A methodology for assessing the environmental safety of construction objects is proposed; the criteria for assessing the development area are determined; methods for solving the problems of development of territories and their environmental safety are proposed. As a method of assessment, the coefficient "degree of real estate concentration" was developed and adopted. The concepts of "environmental reserve", "threshold of environmental safety", "sustainable state range" are introduced, which makes it possible to reliably assess the possibilities of territories for the placement of construction objects with different technogenic potential.Conclusion. It is necessary to legislate, as a mandatory procedure, the procedure for assessing the “degree of concentration of real estate” in administrative territories, especially when planning the construction of a housing stock under the renovation program, when allocating land for new construction, when assessing the environmental impact in the design and examination of construction projects.

Published: May 2022

Background: The nervous system is composed of a complex structure to support its highly organized work. Damage to the working mechanism of nervous systems can exert fatal impacts to the human body. One of the consequences of damage to the mechanism of action potentials is grand mal epilepsy. The purpose of this paper is to determine the structure, function, and mechanism of action of neurons, establish grand mal epilepsy as a result of damage to the working mechanism of neurons, and recognize the ketogenic diet as a non-pharmacological therapy for epilepsy patients. Methods: The research method used is descriptive qualitative research. Results: Nerve cells generally consist of dendrites for receiving stimuli, cell bodies for transmitting stimuli to the axon, and axons for transmitting stimuli to other nerve cells. Grand mal epilepsy is a nervous system disorder caused by the increased activity of sending electrical waves throughout the brain that can reach up to four times faster than normal. However, grand mal epilepsy patients suffer from an excessive number of seizures that may occur at any time. Conclusions: The ketogenic diet method is a high-fat and low-carbohydrate diet method that can reduce electrical activity in the brain. Ketone-containing fats have a stabilizing effect on the central nervous system, contributing to anticonvulsant and antiepileptic effects that may reduce the excessive number of seizures experienced by patients. The application of this diet should be balanced with the provision of additional intake of multivitamins, minerals, and fiber to balance the nutrients the body needs.

Published: May 2022

Skin cancer is a disease that can cause the loss of the ability to regenerate and protect the skin normally. The types of skin cancer that are known are melanoma and non-melanoma skin cancer. Non-melanoma Basal cell carcinoma is a malignant neoplasm originating from non-keratinizing cells in the basal layer of the skin's epidermis. The treatment itself is carried out through the application of immunotherapy, namely the use of drug therapy Programmed Death Ligand 1 (PD-L1). This study aims to see the effectiveness of PD-L1 Therapy as a treatment for basal cell carcinoma. The focus of the study of the article is the integument system, skin cancer, non-melanoma basal cell carcinoma, and the effect of anti-PD-L1 use. The research method used is a literature review from various sources. Skin cancer Basal cell carcinoma attacks the basal cells of the epidermis, causing disruption. Attacks slowly, but when ignored will spread wider and more severe. Through PD-L1 therapy by binding to PD-1 receptors on immune cells, it causes the activation of T lymphocytes as anti-cancer cells in the body that suppress growth while actively controlling tumor cells. Through the use of PD-L1 therapy in treating cancer that attacks basal cells, it will suppress growth, destroy and shrink cancer cells, and increase the body's immunity against cancer cells.
