Published: August 2022

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulting in coronavirus disease 2019 (COVID-19), has caused a pandemic. There is now considerable evidence that neuropsychological functions could be affected. We further tested this hypothesis on a sample of post COVID-19 patients, who, initially, had been severely affected.METHODS: We tested 22 post COVID-19 patients who, after the intensive care unit, were submitted to our rehabilitation unit to be treated for severe post COVID-19 sequelae. All patients were assessed with a comprehensive neuropsychological battery including measures assessing perceptual, attentive, mnestic, linguistic, and executive functions, and overall cognitive status. The patients were also administered rehabilitation measures including scales for investigating aerobic capacity/endurance deficits, dyspnea, and fatigue. RESULTS: Our findings revealed that evidence of neuropsychological disorders on post COVID-19 patients was very limited. Furthermore, COVID-19 severity and other relevant variables were not correlated with patients’ scores on the neuropsychological tests. CONCLUSIONS: We suggest that the relation between COVID-19 and neuropsychological disorders is unclear. New studies and metanalyses are highly required to shed light on this highly complex issue.

Published: August 2022

Creativity has been found to be a fundamental factor in innovation and generating new knowledge and to be influenced by personality. The present study innovatively tested the personality-creativity relationship resorted to the General Factor of Personality (GFP). For a comprehensive and unbiased estimation of the target relation, multiple measures were used, and common method bias was controlled for. The results displayed that the GFP was consistently related to creative self-belief (above .40), other rated creative performance (above .40), and objective tests measured divergent (.31) and convergent (.40) thinking skills. Based on the findings, the present study concludes that the GFP comprehensively profiles creative personalities. In addition, the present study also found that the GFP correlated with creative traits (.75) higher than creative abilities (.36), based on which, we issued a division of creative traits vs creative abilities. The reason for all found correlations can be attributed to that the GFP is the most comprehensive personality structure encapsulating social characteristics. Because of that, the GFP can address as much as possible components of creativity. Suggestions for practical implications and future studies were discussed.

Exploring perceptions of prosocial dog behaviors in a biomimetic robot
Authors: Riddoch Katie , Hawkins Roxanne D , Midson Scott , Cross Emily S.
Published: August 2022

Previously, we identified several behaviors dog owners perceive as important to building and maintaining prosocial bonds between people and their pet dogs. These included (but were not limited to) spontaneous displays of affection and responsiveness. An important next step toward developing and deploying robots as social companions is to now explore how these types of dog behaviors might be perceived when exhibited by a robot. In the present study, we collected videos of dogs exhibiting a selection of the desirable behaviors identified in our previous work, and recreated the clips using the MiRo-E, an animal-like biomimetic robot. We then carried out focus groups to explore people’s perceptions of the behaviors, and examine broader opinions of robotic animals and their potential uses among the general public. Through thematic analysis of datasets collected from 31 participants, we found a tendency for people to make comparisons to real companion animals, as well as a strong desire for features in a robot that resemble real animals – for example, fluid movements, animal-like sounds, and expressive eyes. Responses also suggest that purpose and context are important when judging the appropriateness of an animal-inspired robot, and that the general public have an awareness of ethical issues associated with robots for companionship (privacy, overdependence, and replacement of human/biological social contact). We discuss implications for the study of human—robot interaction, and for those developing social robots for companionship.
Translating the Hierarchical Taxonomy of Psychopathology (HiTOP) from Potential to Practice: Ten Research Questions
Authors: Conway Christopher C , Kotov Roman , Krueger Robert , Caspi Avshalom
Published: August 2022

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a novel diagnostic system grounded in empirical research into the architecture of mental illness. Its basic units are continuous dimensions—as opposed to categories—that are organized into a hierarchy according to patterns of symptom co-occurrence observed in quantitative studies. Previous HiTOP discussions have focused on existing evidence regarding the model’s structure and ability to account for neurobiological, social, cultural, and clinical variation. The present article looks ahead to the next decade of applied research and clinical practice using the HiTOP rubric. We highlight ten topics where HiTOP has the potential to make significant breakthroughs. Research areas include genetic influences, environmental contributions, neural mechanisms, real-time dynamics, and lifespan development of psychopathology. We also discuss development of novel assessments, forecasting methods, and treatments. Finally, we consider implications for clinicians and educators. For each of these domains, we propose directions for future research and venture hypotheses as to what HiTOP will reveal about psychopathology.
The heart as a subjective pacemaker: how experienced time expands and contracts within each heartbeat
Authors: Arslanova Irena , Kotsaris Vassilis , Tsakiris Manos
Published: August 2022

Perception of passing time can be distorted1. Emotional experiences, particularly arousal, can contract or expand experienced duration, via its interactions with attentional and sensory processing mechanisms2,3. Current models suggest that perceived duration is constructed from accumulation processes4,5 and is encoded from temporally evolving neural dynamics6,7. Yet, all neural dynamics and information processing ensue at the backdrop of continuous interoceptive signals originating from within the body. Indeed, phasic fluctuations within the cardiac cycle impact neural and information processing8-15. Here, we show that these momentary cardiac fluctuations distort experienced time, and that their effect interacts with subjectively experienced arousal. In a temporal bisection task, durations (200 - 400 ms) of an emotionally neutral visual shape or auditory tone (Experiment 1) or of an image displaying happy or fearful facial expressions (Experiment 2) were categorised as short or long16. Across both experiments, stimulus presentation was time-locked to systole, when the heart contracts and baroreceptors fire signals to the brain, and to diastole, when the heart relaxes, and baroreceptors are quiescent. When participants judged the duration of emotionally neural stimuli (Experiment 1), systole led to temporal contraction, while diastole led to temporal expansion. Such cardiac-led distortions were further modulated by the arousal ratings of the perceived facial expressions (Experiment 2). At low arousal, systole contracted while diastole expanded time, but as arousal increased, this cardiac-led time distortion disappeared, shifting duration perception towards contraction. Thus, experienced time contracts and expands within each heartbeat – a balance that is disrupted under heightened arousal.
Desired Employment and Local Social Support: The Strongest Predictors for Well-being Outcomes Amongst the Partners of Australian Military Members
Authors: Newfield Chelsea , Johnson Amy , Russell Alex M T
Published: August 2022

Enhancing well-being amongst partners of current serving military personnel is a growing area of interest and concern. Partners of Australian Defence Force (ADF) personnel experience unique challenges because of their military connection above those faced by the broader civilian community. This paper sought to understand undertake an investigation of the most important risk and protective factors which influence well-being in this cohort. This cross-sectional study gathered responses from 444 participants (partners of current serving military members) through an online survey. Bivariate and multivariate regression models found higher well-being scores were associated with younger partners, higher military member rank brackets, existing social support in their location, and partners who were in their desired employment status. Additionally, higher COVID-19 impacts were associated with lower well-being scores. Moving forward, interventions which target social support, desired employment, and periods of national crisis requiring a military response should be the focus. The findings of this study impact policy and programs which aim to provide support to military-connected families.
Higher Education and the Black-White Earnings Gap
Authors: Zhou Xiang , Pan Guanghui
Published: August 2022

How does higher education shape the Black-White earnings gap? It may help close the gap if Black youth benefit more from attending and completing college than do White youth. On the other hand, Black college-goers are less likely to complete college relative to White students, and this disparity in degree completion helps reproduce racial inequality. In this study, we employ a novel causal decomposition and a debiased machine learning method to isolate, quantify, and explain the equalizing and stratifying roles of college. Analyzing data from the NLSY97, we find that among men, a BA degree has a strong equalizing effect on earnings; yet, at the population level, this equalizing effect is partly offset by unequal likelihoods of BA completion between Black and White students. Moreover, a BA degree narrows the male Black-White earnings gap not by reducing the influence of class background and pre-college academic ability, but by lessening the “unexplained” penalty of being Black in the labor market. To illuminate the policy implications of our findings, we estimate counterfactual earnings gaps under a series of stylized educational interventions. We find that interventions that both boost rates of college attendance and BA completion and close racial disparities in these transitions can substantially reduce the Black-White earnings gap.
Practices of Deduction and Induction in the ELT Classroom: A Case Study
Authors: Poudel Kamal Kumar
Published: August 2022

Deductive and inductive approaches are very well-articulated notions in the literature of teaching and learning grammar. This article first conceptualizes deduction and induction from a broader perspective, thereby connecting them to inductive and deductive approaches to teaching grammar. The case study this article draws from was based on the observation of two contextually similar classroom presentations– the first deductive and the next inductive– of an 'outstanding' student teacher as a separate model of each, aiming basically at sketching a comprehensive picture illustrating the classroom actualization of each of these approaches. Comparing the two models, it can be concluded that, regarding teaching and learning grammar, induction aligns more closely to the overall pedagogic essence than deduction does. As a future direction, the study can/should be extended to broader contexts in terms of participants and cases so as to obtain more comprehensive data, hence more reliable results.
Silent Reading and Reading Aloud for Better Comprehension and Speaking Motivation: A Comparative Study
Authors: Subedi Rabindra
Published: August 2022

This article compares the effectiveness of reading aloud and silent reading for comprehension and speaking motivation. The data were taken from the ninth graders of a community school of Jhapa, Nepal. The students were divided into two groups and each were asked to read ten sample comprehension questions. The groups were provisioned to have a silent reading and reading aloud differently. Each group was given just five minutes of time- two times a day- for three weeks and were measured for their scores. Conclusions were drawn comparing the pre- test and post- test results and by closely observing their oral participation in the class. The results showed that reading aloud is more effective than silent reading for comprehension and speaking encouragement.

Perspectives on Women’s Archives. Edited by Tanya Zanish-Belcher and Anke Voss. [Review]
Authors: Harper Christine Froechtenight
Published: August 2022

Perspectives on Women’s Archives satisfies on two counts. This collection of essays provides a useful summary of the development of the field of women’s history since the emergence of the discipline in the 1970s and of the growth of women’s archives from the earliest days of the republic. As such, it might well be incorporated into reading lists for both history and archival studies programs. But the book also offers stimulating prescriptions for the future direction of archives and raises urgent questions about the quality and equality of access in our overwhelmingly digital environment. In this way, it advances the ongoing discussion of why archivists do what we do and how we can do it better—all without the grating neologism “herstory” making more than a token appearance in the text.
A study on the impact of School Area on Mental Stress of Primary School Teachers
Authors: Kumavat Prakashraj
Published: August 2022

Today, the people are experiencing most stressful routine every day. People working under stress in order to achieve the productivity and such stressful situation is beyond their control. High level of mental stress can be harmful to anyone. And hence, people must understand their stress level which normally allow them to utilize their mind optimally in order to perform well. Mental stress among the school teacher may be different according to the area of school, urban and rural locality. The community leaving in rural area normally, live with peaceful life though they suffer from several mental stresses such as unemployment, education system, other administration. The people living in urban area normally, live with busy schedule, standard life style, achieving more education even though they experience more complex and many problems. Therefore, every people live with stress according to their situations and it has its own role according to people situations; no one can prevent mental stress. The aim of this paper is to study impact of School Area its Mental Stress of Primary School Teachers of private primary schools of Mehsana district. For this study a survey method is employed by the researcher. Primary data collected from 100 primary school teachers from rural and urban area of Mehsana District. This study is carried out using Mental Stress Rating Scale (MSRScale) developed by Dr. G. S. Patel as a tool of the research study. Mean, S.D., and T-test were used for the analysis and interpretation of collected data. From the study it is concluded that there is no significant difference about mental stress between rural and urban school area’s private primary school teachers working at private primary schools at Mehsana district which shows that both have equal mental stress at work place.

Role of MGNREGA in Democratic Decentralisation with special reference to the Role of Media and Communication
Authors: Saini Sanjay Kumar , Mathur Ketki
Published: August 2022

Parliamentary system was adopted and democracy was established in India, which is called the largest democratic nation in the world, due to which the principle of decentralized governance has been adopted in India. After attaining independence in India, according to the experiences of the Constituent Assembly, it was not possible to rule the villages of the entire country from the capital Delhi, due to which the emphasis was laid on decentralization by the Constitution to make the country a public welfare state, due to which the transfer of power is above and the role of accountability to higher officials and public representatives began to increase. Decentralization enables all-round development of the local people, while the right of social and economic development along with administrative work is also available to the people's representatives. A truly welfare state can be established only by decentralization of power. It is through this that the qualities of cooperation, accountability, self-reliance etc. develop in the public. India is the largest country in the world, as well as the majority of the country's population still lives in rural areas, due to which Gandhiji called it the "country of villages". But due to the deteriorating economic condition of most of the people in rural areas and lack of employment in rural areas, most of the people are migrating from villages to cities, due to which many villages are in a state of desertion today.
Investment Return Trends of CPSEs in India: Empirical Evidence on Aggregation
Authors: Ghosh Sudipta
Published: August 2022

Background: Investment return is used to determine the efficiency of an investment. The efficacy of diverse investments can be evaluated at a specific time. Thus, investment return is an endeavour to directly calculate the return of a specific investment in relation to its price. Objective: The study primarily aims to examine the investment return trends of the Indian CPSEs by investigating whether there is any deviation between actual values and estimated values of total returns on investment during 2010-11 to 2019-20. Methodology: The deviations between actual values and estimated values of aggregate returns on investment have been tested by Chi-square test. In this respect, the estimated values of aggregate returns on investment are captured by applying the technique of linear regression equation. Results: The findings of the study reveal mix trends in investment returns i.e., positive, negative and zero deviations. However, both positive and negative deviations are marginal during the study period. Conclusion: At aggregate level, no considerable deviations are observed among actual and estimated investment returns in terms of investment ratios selected in the study.
Self-authoring characteristics of the Montessori School graduates
Authors: Bednarczuk Beata
Published: August 2022

The modern world requires a new mindset for people to enable them to become self-evaluating human beings. Kegan (1994) termed this complex system of mind the self-authorship. This is the ability to generate belief systems and intrapersonal states internally. The self-authorship analyses are culturally diverse. This paper presents two theories, namely the concept of self-authorship by Baxter Magolda (1998, 2001) and Obuchowski’s (2000, 2006) theory of self-authoring personality. The latter remains a framework of the description of central psychosocial attributes for the self-authoring personality of Montessori School graduates. The self-authoring studies of diagnostic character aimed at qualification of the authoring personality standard as well as subjective denotations of authoring attributes of the Montessori School graduates. The study covered 69 former students (56.5% women, 43.5% men) of the state Primary Montessori School in Lublin. The self-authoring personality standard was qualified using The Self-Authoring Personality Questionnaire elaborated by Obuchowski and colleagues (Blachnio & Obuchowski, 2011). The personal denotations conferred on authoring attributes were examined by means of the questionnaire My Experiences based on the adaptation of Self-Confrontation Method by Hermans (1991). The level of self-authoring personality in female and male groups was high and characterised by similar values. In the personal statements the persons being examined described themselves as those who perceive themselves as a source of behaviour and the own aims were object of their projects designed for accomplishment in relation with the other people. As follows from the data, the participants of the study acquired skills indispensable for making individual decisions about themselves and the outer world.
Sobre la disipación de energía cinética turbulenta asociada con olas que aún no rompen
Authors: Hernández Olivares Aldo Omar , Ocampo Torres F. J.
Published: August 2022

The turbulent kinetic energy dissipation is an essential quantity in the study of turbulence in fluids. In particular, on the transference of turbulent energy from large to small scales and determining its state of equilibrium and stationarity. This work has the purpose of understanding turbulence generation by non-breaking waves from turbulent kinetic energy dissipation analysis. Different groups of nonbreaking monochromatic waves with different slopes were mechanically constructed in a laboratory, whereby an acoustic device, the wave orbitals velocities were measure in various depths. Considering the inertial subrange in the power spectrum of components of turbulence velocity, a turbulent kinetic energy dissipation rate was quantified. It was detected that the magnitude of the turbulent kinetic energy dissipation rate increases with the wave slope and that deeper is invariant to axis rotations. It was distinguished that most of the profiles of the turbulent kinetic energy dissipation agree with an atypical logarithmic layer. Finally, a term of turbulence production was introduced, relative to nonbreaking wave orbital velocities. Unlike other turbulence production terms or approximations, it adequately reproduces the values of the turbulent kinetic energy dissipation rate regardless of wave slope, which established that the wave orbitals velocities shear is the generator mechanism of turbulence in a fluid under nonbreaking waves.
On new analytical solutions of fractional systems in shallow water dynamics
Authors: Bakıcıerler Gizel , Mısırlı Emine
Published: August 2022

Recently, fractional calculus has got considerable attention from researchers since many problems in natural sciences and engineering are modelled with differential equations having fractional order. The nonlinear coupled time-fractional Boussinesq-Burger (B-B) equation, the nonlinear time-fractional long water wave (ALW) equation, and the nonlinear (2+1)-dimensional space-time fractional generalized Nizhnik-Novikov-Veselov (GNNV) equation are used to express the structure of shallow water waves (SWWs) with different distributions. The analytical solutions of these equations play a substantial role in explaining the properties of complex phenomena in applied sciences. In the current work, we utilize the exponential rational function (ERF) method with the definition of fractional derivative in the conformable sense to achieve new exact traveling wave solutions of these fractional systems. The correctness, validity, and graphics of the new traveling wave solutions are achieved with the aid of Mathematica. Results demonstrate the effectiveness and strength of this technique to solve the system of fractional differential equations (FDEs).
Two measures elaborated for entangled states: Quantum entropy and fidelity using Schmidt coefficients of the reduced density matrix of full TRI
Authors: Dermez Rasim , Tunçer Y.
Published: August 2022

In the present study, we determined quantum entanglement in a full trapped ion (TRI)-coherent system and its dependence on the LambDicke parameter (LDP). We investigated the entanglement in view of two elaborated measurements of the family: entropy and fidelity. We selected three values of the deep LDP to demonstrate the benefits of these two critical measures. The findings obtained in this study showed that the maximum value of fidelity for entangled states is quantified approximately to be 0.35, and the long lifetime is also observed with entropy measurement. The findings suggest that three coupling parameters play a significant role in developing quantum entanglement.
Asymptotic solutions for a continuum model of a DC gas discharge incavities with different geometry
Authors: Córdova Castillo Leonardo , Olvera Orozco José Manuel , Cuevas García Sergio , Figueroa Lara Aldo , Vazquez Hurtado Federico
Published: August 2022

Analytical solutions for a continuum model of a DC gas discharge were obtained by asymptotic approximations. The solutions are one-dimensional and stationary. Three different cavity configurations of electrode pairs were considered, namely, parallel flat plates, concentric cylinders and concentric spheres. The asymptotic approximations consider nonlinear effects that are present in the dynamics of the plasma which are neglected in most of analytical solutions found in the literature. The obtained solutions determine the distribution of positively and negatively charged particles, as well as the electric potential along the space domain. Analytical results agree quantitatively with results from a spectral numerical solution developed for validation purposes. Such agreement was possible in a regime where the rate of charged particle production was assumed to be very small. Finally the limits of this regime are reported.
Transverse momentum dependent parton distribution functions and QCD evolution equations
Authors: Hentschinski Martin
Published: August 2022

We provide an overview over Transverse Momentum Dependent (TMD) Parton Distribution Functions (PDFs). While we will also comment on TMD PDFs in general, we will focus on their use for the description of hadronic reactions in the so-called low x limit. Here $x = M^2/s$ and $M$ is the hard scale of the process, while $\sqrt{s}$ is the center of mass energy of the reaction. We will explain why this are interesting quantities whose exploration serves a manifold purpose. In particular we will explain why these are interesting quantities both for the accurate description of LHC data and why exploration of such quantities is a central goal of the future Electron Ion Collider. In a second part of this talk we will then discuss how perturbative QCD allows us to formulate and solve differential equations, which describe the dependence of this TMD PDFs on various kinematic variables.

Authors: Kovácsné Madar Á. , Takácsné Hájos M.
Published: August 2022

Among the leafy vegetables, lettuce (Lactuca sativa L.) is the most widely grown species in the world. Wide ranges of physical properties of the products are used to assess the degree of maturity. In this study, different lettuce varieties were grown under an unheated plastic tunnel in springtime. We evaluated the agronomic properties of different lettuce varieties, evaluated the condition of the plants, and determined the bioactive substances. Larger head weight can be achieved by the ‘King of May’ butterhead (259.31 g) and ‘Great Lakes 659’crisphead (220.40 g) genotypes. A very strong correlation (r = 0.995) was observed between the lettuce head index, and leaf index and both had a strong positive correlation (r = 0.828 and 0.760) with NDVI. The highest SPAD values were measured for cos lettuce ‘Romaine lettuce’ (44.01) and iceberg lettuce ‘Great Lakes 659’ (42.71). However, these genotypes showed the highest (9.52%; 8.74%) dry matter content, too. The red leaf variety 'Lollo Rosso' had the highest total polyphenol content (181.53 GAE/100 g FW).  Among the evaluated properties, iceberg lettuce showed favorable morphology, plant condition, and good dry matter content. In addition, between the loose-leaf lettuces, the red leaf lollo type was outstanding with bioactive content.
Evaluation of hot pepper (Capsicum annum L.) varieties for green pod yield and quality under rain fed production at Teppi, South Western Ethiopia
Authors: Shamil A. S. , Merga J. G.
Published: August 2022

The trials were designed with three replications in a randomized complete block design in order to evaluate the phenological, growth and yield potential of hot pepper varieties such as ‘Mareko fana’, ‘Melka Zala’, ‘Melka Awaze’, ‘Melka Shote’ and local check. Significant difference was observed between growing year and used varieties. The varieties also performed significantly different (p<0.05) for most of the considered traits in the study. The result revealed that varieties ‘Melka Zala’, ‘Mareko fana’ and ‘Melka Awaze’ were scored highest green pod yield of 8.39, 8.71 and 11.39 ton per hectare, respectively. However, ‘Mareko fana’ variety was susceptible to disease attack as compared to other varieties. Therefore, promoting both ‘Melka Awaze’ and ‘Melka Zala’ varieties for widespread production for Teppi and the areas with similar agro-ecological conditions could contribute to boost the productivity of hot pepper. ‘Mareko fana’ could also be used for dry pod purpose due to its attractive color.
Morphological, physiological features and differences of Vriesea splendens ’Fire’ plants during in vitro multiplication and rooting
Authors: Ördögh M.
Published: August 2022

During in vitro multiplication and rooting of Vriesea splendens ’Fire’, 0.1, 0.2, 0.4 and 0.8 mg l-1 benzyladenine (BAP), benzyladenine-riboside (BAPR), kinetin (KIN), meta-topoline (MT), indole-butyric acid (IBA) and naphthalene-acetic acid (NAA) were added to basal Murashige and Skoog (1962) MS medium. As compared to the hormone-free control, plants developed significantly more shoots on medium supplemented with almost all cytokinins (excepting KIN), especially BAP resulted the highest multiplication up to almost 26 shoots. Enhancement of cytokinin concentrations increased shoot number (and in case of BAP, peroxidase activity) but decreased plant height and rooting parameters. Regarding root production, both auxins were definitely beneficial (0.2 mg l-1 NAA resulted more than 7.5 roots and higher auxin concentrations efficiently stimulate root elongation); however, KIN had similar effects. After a three-month duration time of acclimatization, we observed that plants which were previously cultured on medium containing certain cytokinins (KIN in all doses and 0.1 mg l-1 MT) or both auxins had greater survival, moreover, as negative after-effect, higher cytokinin concentrations reduced the number of survived specimens.
Features of the immunogenetic structure of pigs of domestic breeds,
suitable for xenotransplantation
Authors: Ryk
Published: August 2022

The comparative assessment of the immunogenetic status of pigs of the
Ukrainian meat-type and Myrgorod pigs has been carried out. The specificity of
immunogenic profiles has been evaluated, depending on the history of creation and the
direction of the productivity of animals. It has been found out that 24 specimens of
Myrhorod pigs and 13 specimens of the Ukrainian meat-type pigs have the presence of
genotypes А
-/- and Е
bdgkmp/ bdgkmp which determine the suitability of animals for
xenotransplantation. The Ukrainian meat-type pigs and Myrgorod pigs had the largest
differences in the distribution of alleles by B, E, F, K, L blood group systems with the
presence of the Ladhjk marker allele in the specimens of Myrgorod pigs. (p <0.05).
The possibility of occurrence of reproductive and resistance disorders of pigs in
the selection by blood groups genotypes modeled for xenotransplantation and the
search for ways to their selection overcoming are discussed.
Monitoring of indicators of mineral metabolism in new zealand white
rabbits
Authors: Korniichuk Yu. V. , Grushanska N. H.
Published: August 2022

The quality of livestock products depends on the mineral status of the
animals. The study of mineral elements makes it possible to investigate changes in the
environment and to prevent negative impacts both on the animal organism, the wellbeing of which is completely dependent on humans, and on the human organism, as
the final consumer of food of animal origin. A promising direction in veterinary
medicine is the development of new methods of non-invasive diagnostics for assessing
the state of health and determining metabolic disorders of essential elements in the
body of rabbits, because these methods will be more humane and will facilitate the
work of a veterinary medicine doctor.
The aim of the study was to determine the characteristics of mineral metabolism
in rabbits of the New Zealand white breed by age and sex and the informativeness of
the assessment of metabolism for the use of various biological materials.
The studies were carried out under production conditions on 24 clinically
healthy rabbits of the New Zealand White breed, of all ages and sex. For research,
blood, urine, and hair were taken from the animals. The content of trace elements in
biological materials was determined by the method of atomic emission spectrometry
with inductively coupled plasma.
A significant correlation was revealed between the content in the blood plasma
of rabbits of Calcium with hair (-0.42), Manganese with hair (-0.32), Iron with hair
(0.63), Zinc with hair (0.40), Copper with hair (0.39) and with urine (0.44); between
the content in whole blood of rabbits of Calcium with hair (0.47) and with urine (-
0.33), Manganese with hair (-0.32); between the content of Cobalt with hair in the
urine (-0.35). The dynamics of the content of Calcium, Manganese, Iron, Zinc, Cobalt,
and Copper in the biological materials of rabbits depending on their age and sex was
found out, which is indicated by a significant increase in the blood plasma of Calcium,
Manganese, Iron, Zinc, Cobalt, and Copper in females from 70 to 240 days and a

The article is devoted to the problem of improving the technical level of
tool economy at the enterprise. The efficiency of equipment use, rational use of raw
materials, quality of finished products and improvement of working conditions of
working personnel largely depend on this. In this direction, new tool designs are being
developed, research is being conducted in the direction of introducing new wearresistant tool materials, and tool standards are being developed and updated. It is
shown that today there is a need to improve the provision of enterprises with tools, its
preparation for operation and operation, technical re-equipment of tool economy,
improving its organizational structure and improving tool maintenance. The need of
the enterprise in the tool and the equipment for its preparation for work is defined,
actions on rational use of the tool and improvement of activity of tool economy are
developed. The purpose of research is to improve the instrumental maintenance of
production. The analysis of the technical condition of the tool economy at the
enterprises showed that the technical provision of their equipment for preparation and sharpening of tools, control and measuring instruments is at a low level. Calculations
of the need for a machine tool, the total resource of the tool, the working capital of the
tool, the cost of abrasive tools, the number of workers in the tool industry and the
amount of equipment for the preparation of a particular tool. A set of organizational
and technical measures has been developed, the implementation of which will
significantly increase the level and efficiency of the tool economy, improve the tool
maintenance of the main production. The research was conducted on the basis of wood
production. To make calculations on the effective organization of the tool economy, the
company must have the following data: nomenclature and volume of products;
characteristics of woodworking equipment and tools; characteristics of equipment and
control and measuring instruments used in the preparation of tools for work; list of
workers for tool economy. Mathematical dependences are offered for calculations of
the effective organization of tool economy.
