In the article is given an experimental material devoted to exploration of the impact of peach tree placement schemes in the garden on the quality of lighting of the crown different parts in order to optimize plant placement in intensive gardens. It was revealed significant differences in the inflow of photoactive solar radiation into the tree crown due to tree placement schemes, on the base of studies, carried out in 2015-2017 at Bukhara Agricultural Institute, branch of TashSAU with Lola variety of peach on a weak stock VVА-1. Most of all sunlight - 90 thousand lux comes to the intersections of the garden in spring-summer period. To the central part of crown from 72.0 to 104.7 thousand lux, between trees 69.6-93.9 thousand lux. From studied tree placement schemes, the most solar photoactive radiation is supplied to plants with a thinned scheme from 86.5 to 104.7 thousand lux. This density of placement should be considered as determining when growing peach according to intensive technology.

The Impact

The article aims at assessing the impact of hydraulic characteristics on the habitat quality of mountain and piedmont watercourses. The solution results from the Riverine Habitat Simulation model, where the quality of the aquatic habitat is represented by the weighted usable area (WUA), which is determined using brown trout as the bioindicator. Flow velocity and water depth are basic abiotic characteristics that determine the ratio of suitability of the instream habitat represented by the weighted usable area. The influence of these parameters on the objective evaluation of the habitat quality is the essence of the paper. The measurements were carried out during the summer period at minimum discharges for 17 mountain and piedmont streams in Slovakia. Three methods for assessing the habitat quality were tested, and differences in the results were found to be significant. The evaluation shows the optimum design methods for calculating the weighted usable area.

This article presents the impact assessment results for the spay-dressing of different Metallocene compound fertilizers containing chelated microelements on the yield and quality of winter wheat seeds of the Kazanskaya 560 variety. The research was carried out on the grey forest soils in the Kama region of the Republic of Tatarstan in 2017–2020. The plants were dressed with fertilizers in the autumn and the spring and summer period. In the autumn, we used the fertilizer containing manganese (Metallocene D), and in the spring and summer period (the tillering and earing stages of the winter wheat), we used the Metallocene Universal compound fertilizer with several microelements. During the research, we established that applying the manganese-containing Metallocene D in the autumn has a significant positive effect on the growth and dry biomass accumulation of the winter wheat. The dressing with Metallocene Universal during the tillering and earing stages following the application of Metallocene D in the autumn resulted in an increased/stimulated plant growth and development. The highest yield of winter wheat (3.45 t/ha or 46 % above the reference value) was obtained through the dressing of Metallocene D at a rate of 2 l/ha in the autumn, and the spraying of the plants with Metallocene Universal done twice during the spring and summer period. The autumn application of Metallocene D and the twofold application of Metallocene Universal improve the qualitative parameters of new winter wheat seeds. The use of fertilizers in questions improved the laboratory germination of the seeds and significantly reduced the root rot agent infection rate. The twofold dressing during the spring and summer period following the autumn dressing helped to suppress the most dangerous infections, such as the fusarium blight and the Helmintosporium disease, in the new seeds almost completely. The research conducted showed that Metallocene fertilizers can be successfully used to improve the production of winter wheat and seeds.

Creating favorable conditions for the development of bee colonies, adherence to technological techniques and processes are of great importance in increasing productivity. The article highlights the results of research on the impact of increased subframe space during the wintering of bee colonies on their further development and productivity. In the course of the research, bee colonies were evaluated on the basis of a set of economically useful traits. For research, 2 groups of bee colonies were identified, 10 in each, equivalent in strength and food security, with young fertile queens bred in the same year. The formation of experimental groups took into account the strength of bee colonies, the number of closed brood, the age of the queens, the availability of feed (honey and perga), and the quality of nest cells. These indicators in the experimental groups were almost the same. When preparing bee colonies for winter, the frames in the families of the control group were in the center of the hive, removed the top insulation and unscrewed the sheets by 5–7 sm in the experimental group performed the same actions as in the control winters substituted empty store extensions, thus increasing the subframe space. During the research, honey and wax productivity, strength of families in different periods of the active season and winter hardiness were determined. It was found that bees kept in the hives with increased subframe space, in which 76.1 % less plague was detected, compared with the control group, tolerate wintering well. These families are developing more intensively in the spring and summer period – the advantage in strength was 25.8 % in April, 31.4 % in May, and 31.6 % in June. And further they show higher honey and wax productivity by 24.9 and 32.1 %, respectively.

A study was carried out on the impact of quarrying and crushing waste on the quality of soil in Tumkur District. The quarries located in different parts of Tumkur District produces quarry wastes (aggregates), blasted materials (fly rocks), chemicals (explosives used for blasting) and dust (granite powder) generated from activity are spread and settled in the surrounding area. The soil samples were collected both near and away from the quarry and crushing sites. The collected samples were analyzed for various physico-chemical parameters viz temperature, pH, EC, organic carbon, nitrogen, potassium, phosphorus, zinc, copper, manganese, iron and boron using standard methods. The results revealed the deterioration of soil quality near the quarrying and crushing sites and this can be attributed due to the accumulation of dust. The soil properties are less affected away from the quarry sites.

The Impact

A photovoltaic system is a set of devices that take advantage of the energy produced by the sun and convert it into electrical energy. The impact produced by the possibility of using solar energy in a controlled manner for different uses and purposes has allowed the development of complete systems of transformation, storage and distribution of the energy produced with photovoltaic systems as appropriate. The production of electricity from solar radiation using solar cells and photovoltaic panels is an application that has yet fully disseminated in Third World countries, such as Ecuador. The generation of electric power will depend on the hours that the sun shines and affects the solar panel, the type and quantity of modules installed, orientation, inclination, solar radiation that reaches them, quality of the installation and the power that can be delivered to the user. Ecuador is in a privileged location in terms of solar radiation, because the equatorial line that divides the planet into two hemispheres passes through it, being almost perpendicular to the radiation it receives. In addition, this does not change during the year and there a constant angle of incidence, characteristics that give photovoltaic solar energy a great potential for use. In the investigation, an analysis of how the prices of photovoltaic systems affect the Province of Manabí, the methodology used has been the bibliographic review to know as much as possible about what replenishes the costs of photovoltaic systems.

Schoolrooms in school facilities are the most problematic in maintenance of the internal microclimate and that is why, they have strict hygiene requirements. The generated pollutants in this space are not only affected by the presence of people but especially by solar radiation and orientation of doors and windows to the cardinal points. Considerable importance have the size of the windows, because the room must meet the standards criteria for minimum daily requirement of iluminance Dmin. Increasing outdoor temperature, solar radiation and stay of persons in the classrooms are important aspects that irreversibly lead to deterioration of the microclimatic conditions in these areas. This leads to premature fatigue, loss of concentration, which may lead to headaches, for example. This paper aims to determine the impact of available instruments commonly used in practice to reduce the thermal load of sunlight in the classrooms and determine the actual effectiveness of individual instruments in the real environment.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.

Swallow Function

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.
