An investigation of symbolic factors of cognition and convergent production: Studies of aptitudes of high-level personnel

The formation of a healthy lifestyle and a healthy lifestyle in the work of various activities, developing a program that includes appropriate measures to correct the functional state of employees of nervous and emotional labor, is currently one of the essential areas of occupational health. The study aims to assess the prevalence of behavioral risk factors for health disorders and the effectiveness of measures to correct overstrain in pedagogical and medical workers, depending on the personal level of anxiety. The researchers conducted comprehensive physiological and hygienic studies. We described behavioral risk factors, awareness of health-saving issues based on a questionnaire (346 teachers), a professional graphical assessment of the intensity of efforts. Psychophysical studies help to study the states of various functions of the central nervous system and the cardiovascular system, psychological testing, and general physical performance (GPP) according to the RWC170 test when evaluating the implemented model of motor activity and assess the effectiveness of relaxation in the shungite room. We performed static processing of the data obtained using statistical programs EpiInfo 3.5.2., Statistica 10, Microsoft Excel 2010 using adequate methods of statistical analysis. The study of the prevalence of the factors risky cheek of life for the health of teachers revealed insufficient physical activity (61.1% (95% CI 54.7-67.2)), inadequate sleep duration (46.1% (95% CI 40.0-52.4)), eating disorders (16.2% (95% CI 11.9-21.5)) tobacco smoking (15.8% (95% CI 11.5-20.9)). The developed and implemented regime, which increases the volume of motor activity to 8-9 hours a week instead of 3-4 hours, contributed to an increase in resistance to stress effects, a decrease in the percentage of identified teachers with a low level of physical fitness. A high degree of nervous and emotional tension in the work of general practitioners, the possibility of infection with COVID-19 leads to the formation of a high level of anxiety in a significant part (63.7-72.2%) of medical workers, which indicates the purposefulness of a psychological correction measure. The conducted production studies have shown the usefulness of using in programs for correcting the functional conformity of pedagogical and medical workers, an increase in motor activity using physical culture and sports, and relaxation in the shungite room.

Every country tries to be independent in everything, first of all it is necessary to have a high level of use of own energy resources. Due to the energy crisis, the transition from traditional energy sources to the integrated implementation of alternatives is relevant. The purpose of the study is complex processing of peat for fuel and extraction of humic substances for fertilizer production. Studies of extraction of humic substances were performed on a laboratory stand EI-10, which reproduces the work of a pulsating dispersant with an active diaphragm. The classical technology of extraction of humic substances using chemical methods is based on high temperatures of the mixture, which requires high energy consumption. It was proposed mode of extracting humic component developed by the standard rules, but changes in temperature and duration of extraction processing in an alkaline solution cavitation device. The use of cavitation in the technology of obtaining humic preparations makes it possible to achieve their high physiological activity, high yield of water-soluble organic substances. Briquetting was used to increase the energy density of solid fuel. Based on the research, the technology of obtaining humic fertilizers from peat was developed. The developed technology allows to be integrated into the existing production of the peat briquette plant and will allow to extract as much as possible humic substances from peat with essential reduction of temperature and extraction time with the subsequent application of liquid fraction as fertilizer.

A multisubunit RNA polymerase enzyme is ultimately responsible for transcription initiation and elongation of RNA, but recognition of the proper start site by the enzyme is regulated by general, temporal and gene-specific trans-factors interacting at promoter and enhancer DNA sequences. To understand the molecular mechanisms which precisely regulate the transcription initiation event, it is crucial to elucidate the structure of the transcription factor/DNA complexes involved. Electron spectroscopic imaging (ESI) provides the opportunity to visualize individual DNA molecules. Enhancement of DNA contrast with ESI is accomplished by imaging with electrons that have interacted with inner shell electrons of phosphorus in the DNA backbone. Phosphorus detection at this intermediately high level of resolution (≈lnm) permits selective imaging of the DNA, to determine whether the protein factors compact, bend or wrap the DNA. Simultaneously, mass analysis and phosphorus content can be measured quantitatively, using adjacent DNA or tobacco mosaic virus (TMV) as mass and phosphorus standards. These two parameters provide stoichiometric information relating the ratios of protein:DNA content.

The forte of the Scanning transmission Electron Microscope (STEM) is high resolution imaging with high contrast on thin specimens, as demonstrated by visualization of single heavy atoms. of equal importance for biology is the efficient utilization of all available signals, permitting low dose imaging of unstained single molecules such as DNA.Our work at Brookhaven has concentrated on: 1) design and construction of instruments optimized for a narrow range of biological applications and 2) use of such instruments in a very active user/collaborator program. Therefore our program is highly interactive with a strong emphasis on producing results which are interpretable with a high level of confidence.The major challenge we face at the moment is specimen preparation. The resolution of the STEM is better than 2.5 A, but measurements of resolution vs. dose level off at a resolution of 20 A at a dose of 10 el/A2 on a well-behaved biological specimen such as TMV (tobacco mosaic virus). To track down this problem we are examining all aspects of specimen preparation: purification of biological material, deposition on the thin film substrate, washing, fast freezing and freeze drying. As we attempt to improve our equipment/technique, we use image analysis of TMV internal controls included in all STEM samples as a monitor sensitive enough to detect even a few percent improvement. For delicate specimens, carbon films can be very harsh-leading to disruption of the sample. Therefore we are developing conducting polymer films as alternative substrates, as described elsewhere in these Proceedings. For specimen preparation studies, we have identified (from our user/collaborator program ) a variety of “canary” specimens, each uniquely sensitive to one particular aspect of sample preparation, so we can attempt to separate the variables involved.

Purpose A questionnaire survey was conducted to collect information from clinical audiologists about rehabilitation options for adult patients who report significant auditory difficulties despite having normal or near-normal hearing sensitivity. This work aimed to provide more information about what audiologists are currently doing in the clinic to manage auditory difficulties in this patient population and their views on the efficacy of recommended rehabilitation methods. Method A questionnaire survey containing multiple-choice and open-ended questions was developed and disseminated online. Invitations to participate were delivered via e-mail listservs and through business cards provided at annual audiology conferences. All responses were anonymous at the time of data collection. Results Responses were collected from 209 participants. The majority of participants reported seeing at least one normal-hearing patient per month who reported significant communication difficulties. However, few respondents indicated that their location had specific protocols for the treatment of these patients. Counseling was reported as the most frequent rehabilitation method, but results revealed that audiologists across various work settings are also successfully starting to fit patients with mild-gain hearing aids. Responses indicated that patient compliance with computer-based auditory training methods was regarded as low, with patients generally preferring device-based rehabilitation options. Conclusions Results from this questionnaire survey strongly suggest that audiologists frequently see normal-hearing patients who report auditory difficulties, but that few clinicians are equipped with established protocols for diagnosis and management. While many feel that mild-gain hearing aids provide considerable benefit for these patients, very little research has been conducted to date to support the use of hearing aids or other rehabilitation options for this unique patient population. This study reveals the critical need for additional research to establish evidence-based practice guidelines that will empower clinicians to provide a high level of clinical care and effective rehabilitation strategies to these patients.
