Objectives: This study aims to find and compare the effects of primal reflex release technique and stretching exercises on pain intensity, functional performance, and pain-free sitting duration in patients with coccydynia. Methods: This is a randomized clinical trial. A total of 46 individuals were chosen for the sample based on the inclusion criteria, and they were divided into groups A and B. Pre-treatment values of patients for pain assessment were taken by the Numerical Pain Rating Scale (NPRS), Dallas Pain Questionnaire (DPQ), and pain-free sitting duration (PFSD). Group A received treatment with a hot pack and primal reflex release technique. Group B received treatment with a hot pack and stretching exercises. Each patient received a total of 12 sessions over the course of 4 weeks, 3 sessions per week. After 4 weeks of therapy, both groups were evaluated again. The obtained data were analyzed using SPSS 21. Results: Findings revealed that within-group differences were statistically significant (P<0.05) for all variables. In the primal reflex release technique group, the average NPRS value reduced from 5.565±1.4086 to 1.7391±1.09617, the average DPQ value from 129.967±33.102 to 38.000±26.691 and the average PFSD duration increased from 43.043±20.323 to 368.478±160.464. In the stretching group, NPRS reduced from 6.087±1.345 to 3.695±1.490, DPQ from 116.032±35.054 to 60.608±22.186 and PFSD increased from 28.260±11.928 to 94.130±102.154. The between-group analysis also indicated statistically significant differences in NPRS, DPQ, and pain-free sitting duration with P values ≤0.001, 0.003, and ≤0.001, respectively Discussion: The study concluded that both the primal reflex release technique and stretching exercises were effective in reducing pain and improving functional status with a marked increase in pain-free sitting duration. However, the primal reflex release technique was found to be more useful than stretching exercises in terms of mentioned outcome measures on basis of their mean differences.

Authors: Chumakova V. V. , Chumakov V. F.
Published: March 2023

Relevance. Common fennel is a perennial herbaceous plant, traditionally used as a one- or two-year-old. The culture is cultivated for the production of essential oil, as a medicinal plant and spice. The introduction of highly productive varieties adapted to cultivation conditions can ensure the necessary production volumes of raw materials for the pharmaceutical, food, paint and perfume and cosmetic industries. The creation of new varieties involves the study of the gene pool and the identification of promising genotypes based on valuable traits.

Methods. 37 collection and selection varietals of various ecological and geographical origin were studied. The soil is ordinary medium–sized low-humus medium-loamy chernozem. The productivity of the green mass was taken into account in the phase of technical ripeness for greens (35th days from the beginning of spring regrowth of plants) and processing for oil (the beginning of fruit formation). The area of the plot (depending on the stage of the selection process) is 3–10 sq. m. The repetition is 1–4 times. The method of sowing is wide-row. Humidity and temperature conditions were very different during the years of research, which made it possible to give the studied material a comprehensive assessment.

Results. In the conditions of the zone of unstable humidification of the Stavropol Territory, the greatest variation among the studied cultivars was revealed by the length of the growing season, height, productive longevity, leafiness of plants, yield of green mass and seeds. 8 cultivars distinguished by a complex of signs and properties were included in the selection study. Using the biotype selection method from the resulting hybrid combination with a subsequent series of improving selections, a new variety of fennel ordinary Bachata was created, introduced since 2015. to the State Register of Breeding Achievements of the Russian Federation.

Authors: Scherbakov P. N. , Stepanova K. V. , Burkov P. V. , Rebezov M. B. , Shnyakina T. N. , Barzanova E. N.
Published: March 2023

Relevance. Many scientists reasonably believe that disturbances in microclimatic parameters are the basis for reduced adaptation of the animal organism to environmental conditions, to aggressive stress factors affecting the immune system of animals. This leads to a violation of the barrier function of the lungs, the rapid multiplication of microflora in the mucous membrane of the upper and lower respiratory tract, the development of exudative processes and a bright leukocyte reaction.

Methods. To conduct the experiment in the winter stall period of 2021–2022, calves of the Holstein breed aged 15.0± 5.0 days were selected, from which two groups were formed according to the principle of pairs of analogues of 15 heads each.

Results. The authors found that the use of a «Biological inactivator of toxic gases in the litter» for animals makes it possible to achieve a significant reduction in the amount of ammonia in the air inhaled by calves of the over-lining layer. At the same time, the respiratory function of the animal organism is activated (normalization of the body's homeostasis, improvement of erythropoiesis, reduction of erythrocyte sedimentation rate, increase in the level of alkaline blood reserve, etc.).

Authors: Rezvyakova S. V. , Titov V. N. , Danilov S. Y. , Koneeva O. А. , Zaitsev V. A.
Published: March 2023

Relevance. Winter wheat is one of the main food crops. The introduction of new high-yield varieties and intensive 'high-yield technology' aims to produce high-quality grain of grade 3 or higher, which has high baking qualities.

Methods. The production experiment was conducted out in 2019-2021 in Oryol district of Oryol region. The experimental field was surveyed using the OneSoil precision farming platform. The chlorophyll index was measured using a Yara N-tester. The counts and observations were made according to the Methodology for State Crop Testing (1985). Samples of winter wheat were taken in accordance with GOST 12036-85. Gluten content was determined according to GOST R 54478-2011, weight of 1000 seeds – according to GOST 10842-89, mass fraction of protein – according to GOST 10846-91. Grain moisture content – according to GOST 13586.5-93. Statistical processing was performed according to B.A. Dospekhov (1985) using Microsoft Office Exel computer program.

Results. It was found that measuring the chlorophyll index during the growing season allows you to monitor the nitrate nitrogen content in the plant and timely nitrogen fertiliser application at scientifically justified rates. The new winter wheat varieties Stork and Leonida, when cultivated using 'intensive high yield technology', have been shown to provide high quality grain yields of more than 10 t/ha. In terms of gluten content, the grains of both varieties belong to the third class and in terms of protein content to the second class, which indicates their high baking qualities.

Authors: Zharkova N. N.
Published: March 2023

Relevance. At present, the issues of mineral nutrition of medicinal plants with essential elements remain unstudied, and the lack of certain microelements in soils is an underestimated agroecological factor. This necessitates the study of the effect of different doses of zinc and copper fertilizers on the content of mobile forms of zinc and copper in the meadow-chernozem soil when cultivating Achillea millefolium L. and Tanacetum vulgare L. in the southern forest-steppe conditions of Western Siberia.

Methods. The research objects were meadow-chernozem soil, Achillea millefolium L., Tanacetum vulgare L. The field experiment was conducted during 2012–2015 on the experimental field of the Omsk State Agrarian University. Microfertilizers in the experiments were applied once in the year of planting medicinal plants. Zinc fertilizers (CH3COOH)2Zn) were applied in doses of 20, 40, 60, 80 kg/ha, copper (CH3COOH)2Cu) in doses of 2.4, 4.9, 7.2, 9.7 kg/ha against macrofertilizer (N135P45K45). Soil samples were collected and analyzed annually in the growing phase.

Results. The research revealed that zinc and copper fertilizers on optimal macroelement background at low zinc (< 2,0 mg/kg) and copper content in soil (< 1,5 mg/kg) provided increase of zinc and copper mobile forms content in soil by 108,3% and 54,5% (Achillea millefolium L.) and 672,7% and 61,5% (Tanacetum vulgare L.), respectively, when applied in soil in acetate form. Optimal levels of the content of mobile forms of zinc and copper in the soil were 2.5 mg/kg and 0.17 mg/kg for Achillea millefolium L. respectively, 8.5 mg/kg and 0.21 mg/kg for Tanacetum vulgare L.
Study of the possibility of using data on the content of stable isotopes of magnesium to predict the region of apple production
Authors: Prichko T. G. , Yakuba U. F. , Karpushina M. V.
Published: March 2023

Relevance. Reliable criteria for determining the region of origin of fruit products attract the constant attention of researchers in various countries. A number of approaches aimed at solving this problem are already known, and some progress has been made in interpreting experimental data for fruits on the content of stable isotopes of hydrogen, carbon, oxygen, nitrogen, and sulfur. It is possible that information about the fractionation of stable isotopes of magnesium will allow us to obtain equally important and reliable information to achieve the same goals.

Methods. A mass spectrometer with inductively coupled plasma, standard samples of stable isotopes of magnesium produced in Russia were used to perform the work. The total concentration of magnesium cations was determined by atomic absorption in the flame and on the capillary electrophoresis system.

Results. During the research, the mass and percentage ratio of three stable isotopes (24Mg, 25Mg, 26Mg) in the studied samples of apples grown in different soil and climatic zones was established. The data obtained reflect the relative prevalence of isotopes of this element, expressed in the ratio of the least common isotope to the most common. The deviation of the isotopic composition of Mg prototypes from the conventional standard was determined, significant deviations were obtained for the magnetic isotope 25Mg and non-magnetic 26Mg. The initial data on the fractionation of stable isotopes of magnesium in raw materials growing in different regions were obtained, with the aim of possible subsequent use as indicators in biochemical and physiological studies. A combination of the obtained information on Mg isotopes is assumed, taking into account the content of isotopes of other metals, which will make it possible to specify the region of growth of raw materials with greater reliability.

The Government of Indonesia has committed to support the development of solar power plant, while the efficiency of solar panels still around 5-16%. There are several methods to increase the output power of solar panel, but mostly consume a big portion of energy from solar power plant. The objective is to identify an off-grid solar power plant optimization method with smaller power consumption.  The proposed optimization method is to add a reflector that can be positioned to direct sunlight so that it always hits the solar panel, so that the solar panel is able to produce electrical power optimally. This method can save the use of electrical power, because the weight of the reflector is much lighter than solar panels. The position of the reflector can be adjusted automatically based on feedback from the monitoring system. Off Grid solar system consisting of solar panels, batteries, solar charge controller (SCC), inverters, safety against overloads, short circuits and lightning strikes and mounted reflectors that can be adjusted in position, so that a lot of sunlight hits the solar panels so that the solar panel output power increase. In choosing the type of reflector, several things need to be considered, namely weight, refractive index, size, shading effect and the reflector's resistance to wind, impact and shock. Data retrieval is carried out automatically with a monitoring system to measure and store data when testing solar power system without reflectors and with reflectors in various positions. Data retrieval is based on IEC Standard 61724, while data processing is based on IEA-PVPS T2-01, 2000. Installing reflectors on solar panels is proven to increase the output power of solar panels, where aluminum reflectors and flat mirrors produce the greatest output power at an angle of 83°. Flat mirror reflectors produce a greater increase in solar panel output power compared to flat aluminum reflectors
