Assessment of Static and Dynamic Balance in Swimmers
Authors: Varma Kunal , Gokhale Priyanka
Published: August 2021

Background: Swimming can be defined as an activity in which a person practices a regulated Olympic sport in order to move as fast as possible through the water due to the propulsive forces generated by arm, leg, and body movements overcoming the resistance of water. Swimming is performed in either a supine or prone position with a bilaterally-symmetric motion and is influenced by buoyancy. In other words, it is nearly unaffected by gravity and requires the same muscle exertion of both the right and left extremities. Balance is considered to be an important component of motor performance tasks. It is controlled by the central nervous system with the help of input from the visual, tactile, proprioceptive and vestibular systems (5) Balance can be defined as a condition during which the body's center-of-gravity (COG) is maintained within its base of support (BOS).
Methodology: In this study, 50 Competitive swimmers were included. 36 Male and 14 Female, with a mean age, height and weight of 22.68 years, 175.56 cm and 70.94 kg respectively. Each had a swimming career more than 5 years, Training at least 5 days a week for 2 hours or more with an average of 10.12 years, 5.54 days a week for 2.68 hour training sessions. Static Balance was assessed using Balance Error Scoring System where the subjects were asked to stand with their eyes closed for 20 seconds in 6 Different Positions and the number of errors made were noted. Dynamic Balance was assessed using Star Excursion Balance Test were, a Star was marked on the ground to have 8 directions. The subject stood in the center of the star and had to reach as far as they could in each direction. This distance from the middle to the point of contact of their toe was noted and relative distance was calculated using Limb Length. The Results of both the test was compared with the normal data present.
Result: The result of the test done to evaluate static balance; BESS showed that out of 50 participants 19 had superior balance, 18 had above average balance and 13 had broadly normal balance and the errors on the firm surface and soft surface had a mean and standard deviation of 2 ± 1.12 and 4.1±1.31 respectively. On the other hand, the test done to evaluate dynamic balance; SEBT showed that in each direction on an average the swimmer could reach 119.21±8.39 % relative distance in each direction.
Conclusion: Different tests were conducted in the study to understand if competitive swimmers are somehow weak in terms of static and dynamic balance. The entire study is based on the effectiveness of maintaining and enhancing the static and dynamic stability among the swimmers. This study concludes that competitive swimmers have Superior Static and Dynamic Balance because of strong core muscles used to keep their body streamlined during swimming and good flexibility and neuromuscular feedback.

Published: August 2021

The development of more resistant and inexpensive materials were important for the emergence of composites, materials that are the result of the mixing of two or more distinct components with improved properties. Vegetable fibers reinforced polymer matrix composites help to reduce costs as well as to preserve product quality. Sisal fibers are important due to good impact resistance and availability. Thus, the characterization used infrared spectroscopy and UV-Vis diffuse reflectance. The main purpose was to adapt the methodology used, in order to improve fiber-matrix adhesion, but without risks of fiber defibrillation. Scanning electron microscopy was used to obtain the morphological characterization and the energy-dispersive X-Ray spectroscopy to describe the elemental chemical composition of the fibers. Chemical treatments using NaOH 2% and acetylation with acetic acid and acetic anhydride in the ratio (1:1,5) were important to observe the main changes such as the removal of impurities and the smaller amount of water absorbed in the acetylated fiber, which allows a better adhesion of the fibers with a polymer. After this, the fibers can be used to the production of polypropylene and polyethylene composites that are expected to apply in automotive parts such as bumpers, fuel tanks and internal coatings.

Published: August 2021

The genus Cinnamomum (Lauraceae) consists of approximately 350 species, many of which are essential oil producers, with the most frequently used parts of the plants being dehydrated bark. Therefore, Cinnamomum zeylanicum Blume, known popularly as cinnamon, has the following biological properties: analgesic, antiseptic, antispasmodic, astringent, insecticidal, antifungal and antimicrobial. Thus, this work evaluates the physicochemical properties and larvicidal activity against Aedes aegypti of the essential oil of Cinnamomum zeylanicum Blume leaves that are found in the Municipality of São Luís, Maranhão. The essential oil was quantitatively extracted by hydrodistillation. The physicochemical properties of the essential oil (density, refractive index, solubility, color, and appearance) were determined. The oil was characterized analytically by
gas chromatography coupled to mass spectrometer (GC-MS) and the CL50 of the oil was calculated from the Reed-Muench Pizzi methods, respectively. The yield of the oil was 4.33% of mass per volume, which allowed the identification of 4 components, being the major presence of eugenol that soon was confirmed by the spectroscopic techniques. The essential oil obtained CL50 of 56.49 mg∙L-1. In the identification of the major component and the other components, as well as their quantifications, the techniques were precise and the methods efficient, providing a good analytical performance in the determinations.

Published: August 2021

The aim of the study was to evaluate the effectiveness of P. scabiosifolia in correcting the physiological and psychosomatic state of mice exposed to acute and prolonged whole-body vibration. The effect of a 40% water-alcohol tincture from the roots of P. scabiosifolia was investigated in CD-1 mice under the influence of whole-body vibration induced by a shaker or exposure to road transportation. Emotional, exploratory-oriented and motor behavioral components were observed in the open field. Physical performance was evaluated by the duration of swimming until fatigue with a 7% weight attached to the tail root. Metabolic indices were serum corticosterone, glycogen, lactate and adenosine triphosphate of the liver and skeletal muscle. The orally administered drug at a dose of 5 ml/kg optimized the behavioral reactions of the animals, increased their exercise performance, improved hormonal status, and energy metabolism in liver and skeletal muscle and tissues under the influence of whole-body vibration. The P. scabiosifolia tincture possesses a vibroprotectiveeffect and can be recommended for the prevention and treatment of neurophysiological disorders caused by whole-body vibration, in combination with basic therapy.

Published: August 2021

The importance of state monitoring of water bodies on parasitological indicators is actualized in the article. It was established that summary reports of federal enterprises involved in the state monitoring of water bodies are formed without taking into account natural parasitic systems and insufficient detection of local parasitological pollution. At the same time, the incidence rate in the Russian Federation regarding giardiasis due to the water transport factor has been consistently high for several years. Cryptosporidiosis among the population is not detected due to the use of insensitive methods of diagnosis. With such an unexplored state of factors affecting public health, the level of unidentified etiological causes of acute intestinal infections, upper respiratory tract infections, and community-acquired pneumonia remains high in the Russian Federation: 70% and 90%, respectively. The article presents data on parasitic contamination of water bodies in the catchment area of the Moskva River, obtained with an independent expert survey.

Published: August 2021

Heavy metals are often released into aquatic environments through various sources of industrial processes. However, conventional treatment technologies demand high cost and/or are inefficient for the recovery of these resources. In this context, the technical application of adsorption has been highlighted by its simplicity and practicality, especially when zeolites are used as adsorbents due to their excellent physicalchemical and textural properties, among them: their high availability, high selectivity and low cost. The present work characterized and evaluated the performance of Na-ZSM-5, Na-ZSM-12, NH4-ZSM-5 and NH4-ZSM-12 zeolites on barium adsorption as an alternative for the treatment of produced water. The Na-ZSM-5 and Na-ZSM-12 zeolites were synthesized by the hydrothermal method and subjected to ion exchange to obtain the ammoniacal form (NH4-ZSM-5 and NH4-ZSM-12). The characterization was done by: DRX, SEM, FRX and Adsorption / Desorption of Nitrogen, and barium concentration was measured by Atomic Absorption Spectroscopy (AAS). The adsorption studies were conducted under agitation at the times of 1, 6, 12 and 24 h. The results were promising for this application, because the Na-ZSM-5 zeolite presented the highest adsorption capacity, a fact related to its textural properties (volume and area of micropores).

Published: August 2021

There is a problem of using waste of alumina production from bauxite red mud. Warehousing of it is fraught with ecological catastrophes. Red muds constantly worsen the environment due to dusting and pollution of natural waters. Red mud is a product of bauxite processing. One ton of alumina accounts for 1 to 2.5 tons of red mud. Currently, it is not being processed, despite the availability of 3,000 publications and patents on this topic. One of them is justified by the ambiguity in the economic effectiveness of its use by consumers. In this paper, the options for economic and environmental efficiency of RM use are presented as substitutes for expensive lime and limestone used for purification of industrial gases emitted to the atmosphere in large quantities with toxic sulfur compounds. Laboratory and industrial tests revealed the sorption properties of red muds. When cleaning gases from sulfur emitted into the atmosphere by furnace gases, thermal power plants, sinter machines, and steelmaking furnaces. In addition, the ecological and technological efficiency of purification of sulfur-containing gases released in the areas of granulation of molten blast-furnace slags is shown.

Published: August 2021

The chemical potential change provides a criterion for predicting the spontaneity of any physical and chemical process. If asked to calculate the chemical potential change of a system in which several forces vary, a student might find the task quite complicate at first glance. However, the chemical potential is a state function. This property permits a precise definition of the contribution of each force to the chemical potential when all other relevant parameters are kept constant. The total chemical potential change can easily be calculated by summing up the above contributions. After a brief review of the role played by some parameters of the system, like activity of the components, temperature (T), pressure (p) and surface tension (y), as well as of external fields, i.e. gravitational (, centrifugal (Mcq) and electric field (), an equation for the computation of the chemical potential (μ) including all the above contributes is reported: µ = µ° ′ + RT lna + V¯ (p — p°) — S̅ (T — T°) + Mgℎ + Mcq + Fz Φ + 2yV¯1, bar but also to a chosen value of T, h, r, Φ and r. Finally, applicative examples are illustrated.
HEAVY METAL ADSORPTION FROM A MULTIMETAL SOLUTION BY BENTONITE-KAOLIN-ZEOLITE PELLETS: LINEAR AND NONLINEAR REGRESSION, AND ERROR ANALYSIS
Authors: CARBONEL-RAMOS Dalia Elisa , CHIRINOS Hugo David , AGARWAL Madhu
Published: August 2021

Background: Heavy metal pollution has significant impacts on health and ecosystems; remediation technologies can reduce the cost to solve these problems. Heavy metals present a severe problem in the environment, mainly for their tendency to persist, bioaccumulate and biomagnification in the trophic chain. Removing these toxic compounds from wastewater remains a challenging task. Aim: Heavy metal removal capacity was analyzed using adsorbent pellets made with natural bentonite, kaolin, and zeolite. This study describes the equilibrium adsorption and kinetics of metal removal by using linear and nonlinear regression analysis. Adsorption mechanisms were also analyzed. Methods: The goodness of fit of the adsorption equilibrium data was tested with the four linearized forms of the Langmuir equation, as well as the Freundlich, Temkin, and Dubinin-Radushkevich models. To choose the best-fit model with greater reliability, five error functions were used: R2, X2, SSE, ABS, and ARE. For adsorption kinetics the Pseudo First Order, Pseudo Second Order and Elovich models were studied with linear and nonlinear regression analysis. Results and Discussion: Type I linearization of the Langmuir isotherm showed the best fit for the three metals, with maximum adsorption capacities for lead, copper, and cadmium of 7.27, 1.45 and 0.28 mg/L, respectively. The results show that Pseudo Second Order with linear regression best fitted for lead and copper data and Pseudo First Order model with linear regression for cadmium. Conclusions: Nonlinear regression was found better to fit adsorption equilibrium models and linear regression to fit kinetics models. The main mechanisms responsible for adsorption in the system are thought to be ion exchange between functional groups and cations and surface charge attraction related to Van der Waals forces.

Authors: SHARBA Intisar Razzaq , ALJABERY Hasanat Abdulrazzaq , AL-KHAKANI Manal Farhan
Published: August 2021

Background: Erythroferrone (ERFE) is a glycoprotein hormone synthesis and release by erythroblasts. Recently identified as an erythropoietic regulator and activated in response to stimulating erythropoietin (Epo). In chronic kidney diseases (CKD), anemia is a hallmark disorder due to a decrease in hyposensitive erythropoietic to the Epo; these patients recommended to use of Erythropoiesis-stimulating agents (ESAs). The aim: This study aimed to assess serum ERFE level in patients with CKD and investigate the continuing effects of long-term anemic ESA use associated with markers of erythropoiesis and iron metabolism. Methods: Sixty-five CKD patients divided in two groups, included 30 hemodialyses (HD) and 35 without hemodialysis (non-HD) CKD patients, were compared to 25 healthy voluntaries matched by gender and age enrolled in the current study. Serum ERFE level was measured by an enzyme-linked immunosorbent assay (ELISA). Results: Serum ERFE level was significantly elevated in HD patients median (IQR) about 17.25 (13.4) ng/mL, odds ratio (OR = 10.161), (AUC 0.996) greater than CKD 4(6.1) ng/ml, (OR = 6.295), (AUC = 0.984) p 0.001; also, these are positively correlated with the use of ESA in HD, and CKD (r = 1.00 and r = 0.95) respectively as compared to healthy group 2(2.1) ng/ml. Serum ERFE levels were significantly negative (p 0.05) in both CKD and HD patients related to GFR (r = -0.396, and r = -0.68), transferrin saturation (TS%) (r = -0.842, and r = -0.877), serum levels of Ferritin (r = -0.865 and r = -0.866), and Iron (r = -0.860, and r = -0.851), RBC (r = -0.841, and r = -0.843), hemoglobin (Hb) (r = -0.758, and r = -0.796). Conclusion: The present study demonstrated that elevated serum ERFE levels associated with erythropoietic activity and anemia are higher in CKD with HD and non -HD patients treated with ESA than in non-ESA patients. This study suggested using ERFE as a successful tool for erythropoietic activity inspection in CKD, especially those taking ESAs to treat anemia.

Published: August 2021

Background: The COVID-19 arrived by surprise, and in a very short time, it has changed social habits. The educational environment has not been immune to these changes, and in a short time, it has had to modify its training strategy. A generalized strategy has been distance training through the Internet. However, in many cases, the classroom was moved to a digital platform without considering its effectiveness. One of the links of the training is the assessment. A scheme of formative evaluation in line with distance education is the co-evaluation by peers. These schemes allow feedbacking the processes from results, at the same time that habits are modified, and the motivation is stimulated. Aims: This study has the purpose of evaluating the effects of the evaluation by peers as an active strategy in the transitory model of distance education of undergraduate students in the Universidad Distrital Francisco José de Caldas. The objective is to determine its utility and effects in forming the students in two academic spaces. Methods: These courses are taught in the last semesters of the Technology in Electricity program. The study addresses a quasi-experimental scheme under which two equivalent populations are taken. The first group comprises 31 students from the first semester of 2020, who operated as a control group, and a second group is made up of 34 students from the second semester of 2020 who formed the peer feedback group. As an instrument, the study used classic written tests. Results and Discussion: The data was collected through surveys and were analyzed both quantitatively and qualitatively. The conclusions of the study establish that the technique of peer evaluation is useful for strengthening some aspects of the training process, particularly for consolidation of concepts and motivation towards autonomous study. Conclusions: The comparative results indicate that the strategy has a positive impact in terms of academic performance, but also shows some level of overload in students, a topic not explored, and that raises the need for further study

Background: Thanks to new diagnostic technologies, it is of no doubt that the uterus is no longer considered to be sterile. A disturbed microbiome of endometrium can be a significant reason for preterm birth, infertility, the recurrence of pregnancy loss, and repeated implantation failures in in-vitro-fertilization programs. Aim: Study the endometrial microbiome features in healthy fertile women and in women with multiple in-vitro-fertilization failures. Methods: To assess the differences in the endometrial microbiota of 20 women with infertility and experiencing multiple unsuccessful attempts of in-vitro-fertilization and 15 fertile, healthy women, endometrial microbiome was studied using an NGS of 16S rRNA. Results and Discussion: Lactobacillus (29.4%), Comamonas (16.8%), and Mesorhizobium (6.0%) were the most abundant genera in group of healthy fertile patients, and Lactobacillus (33.3%), Ralstonia (7.9%) and Pediococcus (4.8%) were most abundant in the group of infertile patients. The mean relative abundance of Lactobacillus did not significantly differ between groups and comprised 33.3% in the group of infertile women and 29.4% in healthy fertile women. A considerably higher mean relative abundance of bacteria of the genus Brevundimonas and Ralstonia was recorded in the group of infertile women. The fertile women had a statistically significantly higher mean relative abundance of Acidovorax, Brevibacillus, Caulobacter, Comamonas, Delftia, Distigma, Pseudomonas, Schlegelella, and Thermus. Conclusions: The presented data confirm that endometrium is not a sterile tissue despite long-standing concepts concerning its sterility. Lactobacillus are dominant genera; however, there is no absolute dominance of Lactobacillus over 90%. The mean relative abundance of Lactobacillus in the uterine microbiome in fertile patients and patients with multiple in-vitro-fertilization failures did not differ.

This study was aimed to investigate the effects of isoflavone extracts on the skin improvement during the seaweeds peeling massage. Local anesthetic cream was applied to the control group (left face) with 20 persons and the seaweeds peeling massage was performed after 30 minutes for five minutes. After completion of the massage in the control group, 0.5 mL of isoflavone extract was applied to the test group (right face), and the seaweeds peeling massage was performed after five minutes for five minutes. After 28 days of skin recovery period, the degree of skin recovery was compared in both groups. With respect to the measurement results of skin conditions to compare the effects of seaweeds peeling, the levels of hair follicles (p<0.01), wrinkles (p<0.05), pigmentation (p<0.05), sebum (p<0.05), and porphyrin (p<0.05) in the test group applied with isoflavone extract were lower than those in the control group applied with local anesthetic cream, while pigment under the eyes and skin tone were not different. The results of this study showed that isoflavone extract as a pretreatment was more effective to improve the conditions of hair follicles, wrinkles, pigmentation, sebum, and porphyrin than local anesthetic cream during the seaweeds peeling massage. Therefore, isoflavone extract can be considered to enhance the effects of seaweeds peeling massage.

This study investigated antioxidant and anti-inflammatory in order to confirm the possibility of functional materials that can improve skin diseases using Cordyceps militaris extracts. As a result of measuring the total polyphenol content in the solvent extract of Cordyceps sinensis extracted while decreasing the ethanol content, the content was high in 100% water, 30% ethanol, and 50% ethanol extract. As a result of measuring DPPH and ABTS free radical scavenging activities, it was confirmed that 100% water, 30% ethanol, and 50% ethanol extracts had superior antioxidant activity compared to other solvent extracts. In particular, in the case of 50% ethanol extract, it was confirmed that the antioxidant ability was excellent even at a low concentration compared to other extracts. As a result of confirming the efficacy of reducing skin inflammation against 50% ethanol extract using the HaCaT cell line, it was confirmed that the protein level of the CCL17 and CCL22 cytokine increased by TNF-αTNF-α/IFN-γ decreased by 77.8-81.5% and 61.9-67.4%, respectively. In conclusion, the 50% ethanol extract of Cordyceps militaris is likely to be used as a functional material related to skin diseases in the future.

Feminism sheds light on women's identities in a variety of ways, along with criticism of gender discrimination and male-centered thinking. In particular, Cindy Sherman's selfie, known as a feminist photographer, expresses various women's images, showing a new identity of women. This study examined feminism makeup that expresses women's self-identification in the recent emergence of Me Too and feminism, and analyzed feminism makeup in Cindy Sherman's self-portrait to find out its aesthetic characteristics. First, the nature of Cindy Sherman's feminism makeup was expressed as dominant masculinity. Through various typical forms of beard, he strongly emphasized masculinity, and his eyebrows were thick and dark, and his facial contour was manly. The beard is a symbol of masculinity and a facial expression of social status and character, so Cindy Sherman actively expresses herself as a feminine figure with feminism makeup. Second, Cindy Sherman's characteristics of feminism makeup expressed the characteristics of benignity, which are caused by the confusion of femininity and masculinity. It emphasizes a positive image to exaggerate the image of a man with feminine features and a manly hairstyle and long, voluminous eyelashes. This positive image can also be seen in postmodernism Androgenus look or Genderless look, and is also the best characteristic of feminism makeup. Third, Cindy Sherman's feminism makeup characteristics had the characteristics of typistic femininity. She expresses her female identity through the image of a powerless and shabby woman by turning herself from a young movie star to an old woman. Fourth, Cindy Sherman's feminism makeup characteristics express the characteristics of detachment with ugly beauty. Such makeup is unstable in shape, and there are many distorted or modified images, but Cindy Sherman's selfies also showed this ugly look of herself. Fifth, Cindy Sherman's feminism makeup is bizarre and gives grotesque horror in the form of witches or vampires. Witches and vampires, who lack femininity, expressed feminism not in the image of women obedient to patriarchal men, but rather in horror. Sixth, Cindy Sherman's characteristic of feminism makeup is to portray herself as a clown or a clown, or a clown, to represent a caricature. Sherman's clown series is already well known for its makeup that shows feminism in women. The clown always smiles in the costume, but the inner figure symbolizes the repressed and sad woman herself and is an expression of Sherman's own image.
