Published: March 2021

ABSTRACT Introduction Blood biomarkers are measurable metabolic products that allow objective monitoring of the training process, and their analysis provides an opportunity to improve athletic performance. Objective To evaluate blood lactate concentrations in a group of the Valle League weightlifting athletes as a tool to determine the effects of training and its direct relationship to performance during competition. Methods This is an observational cross-sectional study. Lactate levels of 32 weightlifting athletes belonging to the Valle Weightlifting League were evaluated. Blood samples were taken from the ear lobe to quantify the lactate concentration, using a Scout Lactate analyzer. Samples were taken before and after a high intensity training section consisting of four maximum repetition (MR) sports gestures, in which 5 series and 15 repetitions were performed for each sports gesture, with a rest period of 40 seconds between each exercise. The software program SPSS, version 25, was used to determine the lactate concentrations. Results An average lactate concentration 22.46 mg/dL was obtained for the athletes at rest, and an average of 98.30 mg/dL in the final lactate concentration, after high intensity exercise. Significant differences were found between the initial and final lactate concentrations. Conclusion Lactate concentration increases with physical activity; it varies from one individual to another; and it can be used as a biomarker of intensity of physical activity in the field of sports.

Authors: Araújo Matheus Karia , Barros Rafael Castro Mendanha , Menezes Junior Antônio da Silva
Published: March 2021

ABSTRACT Introduction Cardiac autonomic modulation (CAM) is a result of the balance between the sympathetic and parasympathetic systems. This interaction results in heart rate variation (HRV), analyzed by specific electrocardiographic parameters. These parameters are modified by the practice of physical activity, indicating better cardiac conditioning. Objectives To evaluate the cardiac autonomic modulation of athletes of the XXVIII Ecological Walk at two separate times during their period of physical training. Also, to link the practice of physical activity with stress reduction in these individuals. Methods 24-hour Holter exams were performed at two times (before and after a 2-month period of non-standard physical training), and the results were analyzed using the software programs Epi-Info 7 and BioEstat 5.0. Inferential analysis was performed by the nonparametric Shapiro-Wilk test. Statistical significance was assigned to p values less than 0.05, with 95% confidence interval (95% CI). Results The sample was mostly male (n = 14; 77.78%), with a mean age of 49.55 years. No individual trained for less than 60 days; most (47.06%) trained for 151-200 days, with walking being the predominant modality (64.71%). No statistically significant difference was found in the parameters HRV pNN50 (p = 0.18), rMSSD (p = 0.14) or HF (p = 0.117) after the evaluated training period. Conclusions Participants who are longtime sportsmen and physically active showed parasympathetic saturation, therefore, they did not show significant changes in HRV. Also, low levels of stress were observed in those who practiced physical activity. Level of evidence II; Prognosis Study.

ABSTRACT Introduction Oral injuries are common traumas in combat sports due to the aggressive nature of both offense and defense. Sports mouth guards are made to reduce the risk of traumatic face and jaw injuries and concussions during sports activities. Objective The objective of this study was to determine the prevalence of oral injuries in combat sports and to examine the association between participation levels and percentage of injury occurrence. Methods One hundred and eight participants (mean age: 22.42 ± 2.162 years) who were involved in sparring events were recruited. Data were collected using a questionnaire consisting of 22 questions about the demographic profile of the athletes, their injury experience and type of injuries sustained, awareness and use of mouth guards in sports activities. Descriptive analysis, Chi-square test, and one-way analysis of variance (ANOVA) were applied for data analysis. Results Almost 77% of participants had experienced oral injuries during sports activities and nearly 90% were aware that oral injuries can be reduced by using mouth guards. In addition, 52.7% of participants complained that the mouth guard is not comfortable to use during sports activities. Findings revealed a significant moderate association between levels of participation and number of oral injuries ( p = 0.013). One-way ANOVA showed a significant mean difference in the rate of oral injury for the four levels of participation groups F (3, 104) = 6.21, p = 0.011. Post-hoc comparisons using the Bonferroni test indicated a significant mean difference between university-state levels ( p = 0.033) and university-national levels ( p = 0.028). Conclusion This study revealed that higher levels of participation in sports have a higher risk of injury. It was also found that the discomfort of using a mouth guard can be reduced if the coaches make the athletes wear proper mouth guards that follow the recommended specifications.

Published: March 2021

ABSTRACT Introduction In order to curb the abrupt advance of “Coronavirus Disease 2019” (COVID-19) and prevent the collapse of the health system, authorities around the world have opted for social distancing strategies that include closing gyms, among other measures. Objectives This study analyzed the effect of social distancing on resistance training practitioners’ quality of life and perception of body image in silhouette. Methods The volunteers were contacted through social media; data were collected between April 13 and 19, 2020, through a structured questionnaire, comprised of an Informed Consent Form, four questions about COVID-19 and restrictive measures; and twenty-nine questions designed to characterize the individuals’ habits; as well as the Short Form Health Survey 36 questionnaire. All the questionnaires were applied over the Internet, using Google Forms®. After collection, the data were tabulated and interpreted using the software program AppleNumbers®, and subsequently presented as mean, standard deviation and percentiles. Results The results revealed changes in perception of body image and decreased frequency and satisfaction with training. There was also an increase in sedentary behavior, food intake, and amount of sleep; and a reduction in parameters related to health and quality of life. Conclusions The strategy of social distancing, adopted to curb the progress of COVID-19, has harmful consequences for resistance training practitioners, such as increased calorie intake, stress and anxiety, as well as possible psychological effects. These consequences, in turn, lead to changes in self-perception of body image and in the quality of training.

ABSTRACT Introduction It has been suggested that visceral adipose tissue (VAT) is associated with several non-communicable chronic diseases, but measuring it is difficult. Thus, anthropometry could be used because is easily applied in clinical practice. Objectives The present study aimed to develop and validate VAT estimation equations (Eq) in military men. Methods The sample consisted of 409 (mean age, 36.5 ± 6.7 years) military men in the Brazilian Army (BA) divided into an equation group (EG) ( n = 270; mean age, 37.0 ± 6.3 years) and a validation group (VG) ( n =139; mean age, 36.0 ± 7.2 years). Anthropometric, hemodynamic and DXA body composition evaluations ( GE iLunar ) were performed. The Student’s t test, Pearson’s correlation, and stepwise general linear regression were applied. Bland-Altman graphics were used to assess the concordance between VAT by Eq and by DXA. The level of significance was 95% ( p < 0.05). Results Age, waist circumference (WC), hip circumference and body mass index presented the main significant positive correlations with the VAT-DXA. Four Eq were created Eq1 ( r 2 = 0.793), Eq2 ( r 2 = 0.810), Eq3 ( r 2 = 0.817), and Eq 4 ( r 2 = 0.823) ( p < 0.05). No differences were observed between VAT by DXA and VAT by Eq ( p = 0.982, p = 0.970, p = 0.495 and p = 0.698). Bland-Altman analysis also presented good concordance as the bias was close to zero and was not statistically significant. Conclusion Eq2 (age*13.0 + WC*60.0 - 4975,.5) was more suitable because it is easier to apply, has a higher predictive power (81.0%), less bias (1.86) and validation yielded average VAT values close to those found in DXA. It may still be considered a valuable tool for other extensive epidemiological studies in military men in the BA and can be used in adult men. Evidence Level I: Development of diagnostic criteria on consecutive patients (with universally applied reference ‘‘gold’’ standard).
A new Hyphessobrycon (Characiformes: Characidae) of the Hyphessobrycon heterorhabdus species-group from the lower Amazon basin, Brazil

Published: March 2021

ABSTRACT A new species of Hyphessobrycon belonging to the Hyphessobrycon heterorhabdus species-group from the lower rio Tapajós, state of Pará, Brazil, is described. The new species is allocated into the Hyphessobrycon heterorhabdus species-group due to its color pattern, composed by an anteriorly well-defined, horizontally elongated humeral blotch that becomes diffuse and blurred posteriorly, where it overlaps with a conspicuous midlateral dark stripe that becomes blurred towards the caudal peduncle and the presence, in living specimens, of a tricolored longitudinal pattern composed by a dorsal red or reddish longitudinal stripe, a middle iridescent, golden or silvery longitudinal stripe, and a more ventrally-lying longitudinal dark pattern composed by the humeral blotch and dark midlateral stripe. It can be distinguished from all other species of the group by possessing humeral blotch with a straight or slightly rounded ventral profile, lacking a ventral expansion present in all other species of the group. The new species is also distinguished from Hyphessobrycon heterorhabdus by a 9.6% genetic distance in the cytochrome c oxidase I gene. The little morphological distinction of the new species when compared with its most similar congener, H. heterorhabdus, indicates that the new species is one of the first truly cryptic fish species described from the Amazon basin.

Published: March 2021

Abstract Palynological data have been used in Vernonieae for generic and specific delimitations, particularly in the Lepidaploinae subtribe. For this reason, pollen studies in the genus Lepidaploa are important to solve taxonomic conflicts. We characterized 23 species of Lepidaploa searching for morphological differences among themselves. We then compared the data obtained with other genera of the Lepidaploinae. The results show that the species have pollen type “C” (with polar lacuna) or “G” (without polar lacuna), oblate-spheroidal, subprolate or prolate-spheroidal, 3-colporate and equinolophate. The pollen types and shape of pollen grain are taxonomically useful. Pollen morphology is useful to distinguish species and genera of Lepidaploinae. Together with macromorphological data it is possible to delimit Lepidaploa and the species studied here.
Influence of basalt micro-fibres on the abrasion resistance of concrete in hydraulic structures
Authors: Omoding Nicholas , Cunningham Lee S. , Lane-Serff Gregory F.
Published: March 2021

In hydraulic structures, abrasion resistance can be a significant driver in concrete specification. Basalt micro-fibres represent a potentially sustainable construction product and have been shown to provide various benefits in concrete, however the implications for hydrodynamic abrasion resistance are to date unclear. This paper is the first investigation of its kind to examine the abrasion resistance of basalt fibre-reinforced (BFR) concretes using the ASTM C1138 underwater test method. Towards this, concretes incorporating fibre dosages of 0.5, 1, 1.5 and 3 kg/m3 were tested. The relationships between concrete abrasion and its fundamental mechanical properties are evaluated. For the particular concretes examined, it is found that based on the Shapiro-Wilks tests at 95% confidence, abrasion loss in BFR concretes followed a normal distribution; the use of basalt fibre in contents of up to 3 kg/m3 did not have a significant effect on abrasion resistance, compressive and tensile splitting strengths, as well as modulus of elasticity. It can be concluded that basalt micro-fibre can be used for their other attributes such as controlling bleeding, shrinkage and plastic cracking in concrete hydraulic structures without deleterious effects on abrasion resistance. The regression models proposed to predict concrete abrasion loss from its mechanical properties were found to be only significant at 48 h for compressive strength and 24 h for both tensile splitting strength and modulus of elasticity.

Published: March 2021

Significance Statement

Most kidney failure prediction models have been developed and validated in cohorts of patients with a wide range of disease severity, without accounting for the competing risk of death. Models recommended by guidelines, currently used in the clinic, have not undergone a head-to-head comparison. This study provides a comprehensive external validation of kidney failure prediction tools in two cohorts of patients with advanced CKD, taking the competing risk of death into account. Models that predict over a longer time frame of 5 years overestimate risk due to the competing risk of death. In patients with advanced CKD, the eight-variable 2-year Kidney Failure Risk Equation is recommended for short-term predictions surrounding preparation for RRT. The 4-year Grams model, which accounts for competing risk, is most suitable for longer-term predictions.

Background

Various prediction models have been developed to predict the risk of kidney failure in patients with CKD. However, guideline-recommended models have yet to be compared head to head, their validation in patients with advanced CKD is lacking, and most do not account for competing risks.

Methods

To externally validate 11 existing models of kidney failure, taking the competing risk of death into account, we included patients with advanced CKD from two large cohorts: the European Quality Study (EQUAL), an ongoing European prospective, multicenter cohort study of older patients with advanced CKD, and the Swedish Renal Registry (SRR), an ongoing registry of nephrology-referred patients with CKD in Sweden. The outcome of the models was kidney failure (defined as RRT-treated ESKD). We assessed model performance with discrimination and calibration.

Results

The study included 1580 patients from EQUAL and 13,489 patients from SRR. The average c statistic over the 11 validated models was 0.74 in EQUAL and 0.80 in SRR, compared with 0.89 in previous validations. Most models with longer prediction horizons overestimated the risk of kidney failure considerably. The 5-year Kidney Failure Risk Equation (KFRE) overpredicted risk by 10%–18%. The four- and eight-variable 2-year KFRE and the 4-year Grams model showed excellent calibration and good discrimination in both cohorts.

Conclusions

Some existing models can accurately predict kidney failure in patients with advanced CKD. KFRE performed well for a shorter time frame (2 years), despite not accounting for competing events. Models predicting over a longer time frame (5 years) overestimated risk because of the competing risk of death. The Grams model, which accounts for the latter, is suitable for longer-term predictions (4 years).
Analysis of beam-column elements on non-homogeneous soil using the differential transformation method
Authors: Carvajal-Muñoz Juan Sebastián , Vega-Posada Carlos Alberto , Saldarriaga-Molina Julio César
Published: March 2021

This paper describes an analytical approach to conduct an analysis of beam-column elements with generalized end-boundary conditions on a homogeneous or non-homogeneous Pasternak elastic foundation. The mathematical formulation utilized herein is that presented by the senior author in a recent work. The differential equation (DE) governing the behavior of the beam-column element is solved using the differential transformation method (DTM). The DTM offers practical advantages over other conventional approaches when solving the proposed structural model. The proposed formulation provides the flexibility to account for i) combined lateral and axial load at the ends of the element, ii) homogeneous or non-homogeneous soil, iii) Pasternak elastic foundation, and iv) an external arbitrary transverse load acting on the element. The effects of various slenderness ratios, pile-soil stiffness ratios, and classical and semirigid boundary conditions can be easily studied with the proposed formulation. Examples are presented to validate the accuracy of the model and its applicability over a wide range of analyses.

It is very difficult to select the right supplier from supply base for the global supply chain due to many challenges and problems especially for the developing countries such as Pakistan. In the present study primary data is collected via adopted questionnaire from cases of the total 170 cases from Kotri manufacturing companies of Sindh, Pakistan. For the analysis of gathered data many tests were applied such as reliability test, factor analysis and structural equation modelling in SPSS and AMOS software. Findings, revealed the partial mediation for both quality and delivery variables in the presence of mediating variable information flow. However, the quality confirmed the more important variable for the supplier selection in manufacturing companies of Kotri, Sindh, Pakistan due to higher beta value than delivery variable. In the past research scholars explored the direct relationship between quality and delivery for the supplier selection but, in the present mediating variable information flow is introduced in order to verify the strength of studied variables. Lastly, based our limited knowledge this would be the first study conducted on Kotri manufacturing companies of Sindh, Pakistan.

Los principios de UNIDROIT sobre los contratos comerciales internacionales y los efectos derivados del Covid-19 sobre las relaciones contractuales: una perspectiva desde el Derecho español
Authors: Díez Soto Carlos Manuel , González Pacanowska Isabel Victoria
Published: March 2021

La Nota publicada el pasado 15 de julio 2020 por el Secretariado de Unidroit, relativa a los Principios Unidroit sobre Contratos Comerciales Internacionales en la crisis sanitaria de la Covid-19, pretende ofrecer una guía sobre el modo en que los Principios pueden servir como un útil instrumento para afrontar, en términos jurídicamente adecuados, algunos de los problemas típicos que se están suscitando como consecuencia de la pandemia y de las medidas adoptadas para paliar sus efectos, así como la crisis económica derivada. La magnitud de la crisis impone sin duda la necesidad de articular medidas legales específicas, inspiradas por criterios de justicia distributiva (y no solo conmutativa). Se trata, además, de evitar que el recurso a los instrumentos generales provoque el colapso de los tribunales, a lo que se une el inconveniente de la disparidad de criterios y la inevitable lentitud en la construcción de guías jurisprudenciales. La legislación de emergencia no podrá, sin embargo, ofrecer una solución satisfactoria a todos los conflictos que se vienen planteado y seguirán surgiendo en el futuro próximo, y es en este terreno donde tendrá que acudirse a los conceptos generales. La Nota aporta interesantes perspectivas a la hora de interpretar y aplicar las normas nacionales que regulan las instituciones básicas de obligaciones y contratos, en especial las relacionadas con las nociones de fuerza mayor/caso fortuito, y excesiva onerosidad sobrevenida/rebus sic stantibus. En este artículo, siguiendo una sistemática expositiva paralela a la de la propia Nota, se centra el foco, no tanto en la legislación de emergencia, sino más bien en el modo en que tanto los Principios como las sugerencias de la Nota pueden ser aprovechados para plantear posibles soluciones en el contexto del ordenamiento jurídico español, con una atenta consideración a los planteamientos de la jurisprudencia, sobre todo de los últimos años, y al entendimiento de las nociones de fuerza mayor y caso fortuito, imposibilidad, excesiva onerosidad sobrevenida, así como el ámbito de aplicación, los presupuestos y los efectos de la regla rebus.

A liquid fluid flow that is driven by a centrifugal pump past the ventury channel needed to produce the vacuum conditions at the ventury vacuum pump. The amount of vacuum pressure produced by ventury is influenced by the increase of flow rate due to the channel cross section that follows the Bernoulli principle. The flow rate on the channel is affected by the discharge generated by the pump that follows the law of continuity. In addition to speed, the pressure of channel input is also a variable that affects ventury vacuum pressure. Pressure losses and flow discharge caused by the connection or turn of the pipe arising from the installation design, will affect the performance of the Setrifugal pump in the form of discharge flow and pressure that ultimately strongly affects the rally Venturi vacuum work.
Therefore, it is necessary to evaluate the influence of the design of the istalation associated with the position of ventury mounting and the direction of the flow to the pressure and discharge of the vacuum to be the primary purpose of this research so that the variables are obtained The performance of a ventury vacuum pump.
In this research the placement of vacuum ventury in several positions, namely vertical position, horizontal position and tilt position 45o. Then measured parameters are occurring, such as discharge fluid flow, liquid fluid pressure and vacuum pressure occurring on the pipe.
From this study obtained optimum performance on the installation with a sloping ventury position of 45o with the direction of the downward flow, which resulted in the lowest vacuum pressure of-65 CmHg with ventury suction flow of 33.01 liters/minute.

Utilization of waste rice husk, especially in South Kalimantan, is not very efficient. Therefore, it needs more maximal utilization, for example it is used to manufacture alternative fuels in the form of charcoal briquettes. The effort to maximizing utilize waste rice husk as charcoal briquettes, we need to know the combustion characteristics.
The study, we used a variation of the ratio between siam rice husk charcoal in the peat region areas and pandak is located in the tidal areas with adhesives of 5%, 10% and 15% respectively. Characteristics of testing follows SNI 01-6235-2000. Based on the results of the study, it is known that the charcoal waste of rice husk waste with a percentage of 5% adhesive has a good value compared to the addition of other adhesives, where siam rice husk has a water content of 4.9% and pandak has a higher moisture content of 5.0%, whereas for husk heating values Pandak rice is larger with a value of 5063.6 cal / gram, compared to siam rice husk with a value of 4894.5 cal / gram.

Regional development engineering in coastal areas, tidal land reclamation, delta area reclamation and port planning, tidal knowledge is very important. Tides mainly occur due to the gravitational forces of the moon, sun, and other planets. The influence of different gravitational forces can be predicted precisely because the rotation and revolutionary movements of the earth, moon, sun, and other planets take place with very high order. The tidal period every day is mainly determined by the rotation of the earth with a 24-hour period. Influence of the sun even though its attraction is only half that of the lunar pull, its influence should not be ignored As understood months around the earth with a period of about 29.5 days. When the position of the moon-earth-sun is in line, the tidal forces of the sun and moon strengthen each other. At that time spring tide occurred. Whereas if the sun-earth forms an angle of 90 degrees, then the minimum tides occur (neap tide). The two conditions are about 7 days old, according to the moon's revolution. Because of the influence of the inertia of the mass of water, the spring and neap tide occur between one and three days after these extreme conditions occur.
In short-term studies often researchers take extreme conditions, namely during the tidal peak and peak tide (spring tide), because it does not require a long time compared to researching during a longer tide period. The research approach that will be carried out is whether the tide and peak peaks still occur 1-3 days after the full moon and the dead moon, whether there is a change in the height of the tide and ebb during a certain period due to global warming.
As a result of global warming, it is also an effect on the water level of the Barito River. There was a decrease in the maximum water level which previously was around 3 m, now only around 2 m, the minimum water level previously around 2 m was now below 1 m. This will affect the hydrotopographic conditions of tidal swamp land, land that was previously type A can change to type B and so on. The highest tides on the Barito River often occur in the dead months, namely the 1st and 29th of the Hijri.

Impact testing is needed to measure the toughness of an object that requires a specimen as material to be requested. Where Impact testing specimens from metal that be moulded by casting cannot be made perfect because the angles of the notch are very difficult to make. For this reason, researchers try to make plastic specimens produced from 3D printers where notches or angles in the test specimens can be made precisely using a 3D printer. The design pattern of the plastic test specimen was made according to ASTM standard and tested using the Charpy test having a length of 73.6 mm, a width of 12.7 mm and a thickness of 10 mm, a notch shaped "V" with an angle of 45 ° alongside a notch height of 2, 54 mm . after that it is drawn 3D using 3D software then saved in STL file format then opened, saved and printed in the default software of the 3D printer. The variables researched are layer thickness and temperature. Analysis of the plastic test specimen by using a 3D printer the first is Failed in Impact testing occurred because the placement of the specimen on the charpy compressive test instrument laying would not be straight with the pendulum. The notch angle should be straight with the pendulum by checking the straight position by being photographed from the back and front of the specimen and pendulum. The second obtains if it gets a gap in the slice of the plastic specimen from the type of layer, the energy provided is smaller so that the energy absorbed can be read in the testing process through charpy. The third the plastic specimens code A and code B is getting more layers, the more energy absorbed. The fourth which shows the difference in the nozzle temperature for the plastic test specimens that are set using a nozzle temperature of 200 ° C, the initial energy given is greater and the specimen is stronger receiving the energy load than test plastic specimen using a 180 ° C temperature nozzle.
