Body schemata of rats Rattus norvegicus were studied using a procedure according to which the animals had to take into account the enlarged boundaries of their bodies. Rats of experimental and control groups were trained to get the bait putting the head through the hole of a certain size. Then the boundary of the body of rats of the experimental group was increased using a small cylindrical object mounted on the crown of their heads to prevent putting through the hole. For the control group rats, the size of the hole through which the animals have been trained to take the bait was reduced to prevent the penetration of the rat’s head. In the subsequent experimental series, the arrangement of the holes was varied. It is shown that, with the increased boundaries of the body, the rats are capable of forming a new learning adequate to situation change, which was reflected in the reliable reduction of the time for solving the problem by the end of each series and the reduced number of unsuccessful attempts. Rats of the experimental group also showed the ability to transfer previously gained experience to the new situation, when the location of the holes in the box was changed. The data suggest that the rats are able to modify the body scheme in accordance to change in its physical boundaries.

This study was performed to clarify the differences of the body heats between electroacupuncture analgesia (EA) and anesthesia by ketamine hydrochloride (ketamine anesthesia) in dogs. Nine clinically healthy dogs were divided into ketamine anesthesia (control: 5 heads) and EA (experimental: 4 heads) groups, respectively. The acupoints GV-5 and Bai-Hui were used. The infrared thermographic system was used to determine the body heats. The body heats was determined at areas such as the dorsocranial (DCr), dorsocaudal (DCd), ventrocranial (VCr) and ventrocaudal (VCd) regions, on pretreatment, 10, 20, 30, 50 and 90 minutes after treatments, respectively in control and experimental groups. The body heats showed decreasing tendency until 30 minutes after ketamine injection, and then showed increasing pattern until 90 minutes after at all areas investigated in the control group. However, no significant differences of the body heats in the DCr, DCd, VCr and VCd regions were found in the control group. On the other hand, the body heats showed increasing tendency until 30 minutes, and then showed decreasing pattern until 90 minutes after EA, in the experimental group. The significant difference was observed at 30 minutes in the DCr region, and also at 10, 20 and 30 minutes in the DCd regions in the experimental group ( p < 0.05). The significant differences of the body heats were detected at 20 minutes in the DCr region, at 30 minutes in the DCd region and at 30 minutes in the VCd region between the experimental and control groups ( p < 0.05). In conclusion, EA increases of the body heat in the contrary to that of ketamine anesthesia.

Purpose: to determine the dynamics of physical fitness of 5 grade pupils under the influence of outdoor games with elements of martial arts. Material and methods. The research was carried out in Kharkov, on the basis of a comprehensive school of I-III levels No 118. The study involved 40 students of 5t grade (20 experimental and 20 control groups). In the educational process, which was developed on the basis of the curriculum in physical culture for general educational institutions of grades 5-9 (approved by order of the Ministry of Education and Science of October 23, 2017 No 1407, we included outdoor games with elements of martial arts). During the research, the following methods were used: theoretical analysis and generalization of literary sources, Internet data, generalization of theoretical and practical experience of specialists in the field of physical culture and martial arts, pedagogical research, methods of mathematical statistics. Results: the analysis of the results obtained indicates that the indices of physical fitness are better in the experimental group than in the control group. The results of the arithmetic mean indicators when performing a 30-meter run in the experimental group were 6,45±0,1, in the control group 6,46±0,11 s; shuttle run test 4×9 m (s) in the experimental group – 11,74±0,16, in the control group - 11.83 ± 0.14; in the test, the long jump from the spot (cm), 146,55±3,05 and 146,55±3,05; indicators of the test performance long jump with a run (cm) in the experimental group are within 245-310 cm, in the control group 240-320; when throwing a small ball at a distance (m) in the experimental group – 22,45±1,12 and the control group – 20,15±1,05; indicators of pupils in the experimental and control groups in the test of raising the body in sitting for 30 seconds 23,4±0,82 and 20,65±0,85. Conclusions. Modern trends in physical education in general educational institutions require the teacher to search for new means and methods to expand the motor experience of students. This can be achieved through the targeted use of specialized outdoor games with elements of martial arts. After the pedagogical experiment, the level of competence of students in the experimental group is higher than that of the control group. The high level of competence in the experimental group ranges from 15 to 80 %, sufficient - from 20 to 50 % and average - from 15 to 35; in the control group, students predominantly have sufficient from 30 to 40 and average from 25 to 60 % and high from 15 to 60 %. The results of the indices of the coefficients of variation of the experimental and control groups are stable in terms of the general population in the tests: running 30 m (sec) – 7,42 and 7,79; shuttle run 4 × 9 m (s) 6,37 and 5,41; standing long jump (cm) 9,29 and 8,86; long jump with a run (cm) 6.77 and 7.87, moderately stable: throwing a small ball at a distance (m) 22,36 and 23,29; raising the body in a sitting position in 30 seconds (number of times) and 18,6.

In Bangladesh some researchers have done several studies to find the correlation of simple diffuse goiter with arsenic level but no one conducted any study to find the differences of urinary iodine, urinary arsenic, radioiodine uptake, the thyroid stimulating hormone (TSH) and free thyroxin (FT4) levels between goitrous and non goitrous. That is why, in this research an attempt has been made to compare the urinary iodine, urinary arsenic, radioiodine uptake, TSH and FT4 levels between experimental group with simple diffuse goiter and healthy control group. In this study another purpose has also been made to find the associations between different pairs of variables for both experimental and control group. In this study we have tried to find the impacts of arsenic level on simple diffuse goiter. This is a case-control analytical study. The study is carried out in the Institute of Nuclear Medicine and Ultrasound, in collaboration with the thyroid out patient department of Bangabandhu Sheikh Mujib Medical University. A total of eighty five (85) subjects are included in the study. Among the 85 subjects, a sample of forty five is considered for experimental group with simple diffuse goiter and another sample of forty is considered for healthy control group without any thyroid disease. From the experimental results it has been found that, the arsenic levels, FT4 and radioiodine uptake levels at 2 hours between the experimental and control groups are significantly different but the urinary iodine levels, TSH levels and radioiodine uptake levels at 24 hours between the experimental and control groups are not statistically different. From the experimental results it has also been found that there is significant differentiation between experimental and controls groups in respect of association between different pairs of variables. In this study, another significant finding is that iodine deficiency is not only the factor of causing simple diffuse goiter, but arsenic level is also one of the most important factor of causing simple diffuse goiter. Key words: Iodine deficiency, Simple diffuse goiter, Urinary arsenic, Statistical analysis, Association, Experimental and Control groups  DOI = 10.3329/dujps.v7i1.1224 Dhaka Univ. J. Pharm.

This study aims to investigate the possible effects of peripheral learning on elementary EFL learners’ grammar improvement: the case of prepositions of time and place. Two elementary classes were selected as experimental and control groups. Before beginning the treatment, a grammar test was administered to both the groups as a pre-test. Then, as treatment, the experimental group was exposed to realia, pictures, posters and texts, while the control group was not. After term-long treatment of 10 weeks, the two groups received the same grammar test as post-test. The results of t-test showed that the experimental group improved their grammar ability, i.e., knowledge of prepositions of time and place more than their friends in the control group. The finding of the study may open an optional path for teachers to include some peripheral materials in their teaching environment to further invest on unconscious learning abilities of the students.   Keywords: Peripheral learning, reposition of time, prepositions of place, grammar.
