The era of the COVID-19 pandemic has changed the way people live, from offline to online. This study discusses the effect of thrift shop marketing communications on the level of fashion consumption during the pandemic. The purpose of this study is to determine the level of consumption of a person in shopping, especially Thrift Shop goods. The research method used is a quantitative approach with simple random sampling technique. The results showed that from the analysis of data calculations carried out 53.2% of respondents made the last purchase, then 32.4% had bought from the previous 2 months and 14.4% had bought 1 month earlier, so Ho was accepted while Ha was rejected. It can be concluded that the phenomenon of Thrift Shop products does not affect the consumption pattern of people's fashion products because most of the purchasing trends for Thrift products during the last three months are still passive in purchasing Thrift products on various E-Commerce platforms and social media.

Violencia política y movilización popular: chihuahua (México), 1972
Authors: Necoechea Gracia Gerardo , De Los Ríos Merino Alicia
Published: September 2021

El presente artículo trata del surgimiento del Comité de Defensa Popular, en Chihuahua en el año de 1972. El ensayo propone que este Comité surgió debido a la convergencia de luchas sociales que venían ocurriendo durante la década de 1960, de manera separada. La convergencia ocurrió, primero, debido a la acción de un grupo político-militar y la represión que siguió; y segundo, debido a las redes de relación que se habían tejido entre quienes participaron en las distintas luchas sociales. El artículo, por esa razón, describe la trayectoria de los grupos armados y de los movimientos estudiantil, urbano popular y sindical: el CDP fue punto de llegada para todos ellos. La protesta social posterior evidenció un cambio cualitativo, debido a la unión de fuerzas y coordinación de acciones.

Observing and quantifying kinematic properties and lagrangian coherent structures of ocean flows using drifter experiments
Authors:   , Getscher Timothy
Published: September 2021

This thesis analyzes data from two types of unique drifter experiments in order to characterize two aspects of ocean flows that are often difficult to study. First, vertical velocities and their associated transport processes are often challenging to observe in the real ocean since vertical velocities are typically orders of magnitude smaller than horizontal velocities in mesoscale and submesoscale flows. Second, Lagrangian coherent structures (LCS) are features which categorize ocean flows into regimes of distinct behavior. These structures are also difficult to quantify in the real ocean, since sets of gridded trajectories from real ocean data (rather than model fields) are rarely available. The first experiment uses drifters drogued at multiple depths in the Alboran Sea to observe and characterize the ocean’s vertical structure, particularly near a strong front where vertical velocities are expected to be much stronger than other regions of the Ocean. The second experiment uses a roughly gridded pattern of surface drifters in the Gulf of Mexico to study LCSs as quantified by methods from dynamical systems such as finitetime Lyapunov exponents (FTLEs), trajectory arc-length, correlation dimension, dilation, Lagrangian-averaged vorticity deviation (LAVD), and spectral clustering. This thesis includes the first attempt to apply these dynamical systems techniques to real drifters for LCS detection. Overall, these experiments and the methods used in this paper are shown to be promising new techniques for quantifying both the vertical structure of ocean flows and Lagrangian Coherent Structures of flows using real drifter data. Future work may involve modified versions of the experiments, with denser sets of ocean drifters in the horizontal and/or vertical directions.
Recent Advance on Vitamin D in Athletes

Published: September 2021

PURPOSE: Vitamin D plays important roles in calcium homeostasis and bone metabolism. Since vitamin D receptors (VDRs) are located in a variety of organs, including skeletal muscle, vitamin D has potentially widespread effects. The purpose of this review was to summarize the current understanding of the effects of vitamin D on muscle function and exercise performance in athletes.METHODS: In this narrative review, we summarized previous studies by searching the literature in the PubMed, Google Scholar, and Science Direct databases.RESULTS: Vitamin D has been shown to regulate multiple actions in skeletal muscle tissue, such as myocyte proliferation and growth via genomic and non-genomic molecular pathways. Higher levels of vitamin D are associated with improved skeletal muscle function and exercise performance. Moreover, in some studies, vitamin D supplementation has beneficial effects on muscle strength in athletes, especially those who are vitamin D-deficient.CONCLUSIONS: Vitamin D appears to have beneficial effects on muscle and exercise performance in athletes. However, more studies are needed to clarify the action and dosage of vitamin D in athletes.

Authors: Chen Nan , Kim Chang Gyeong , Lee Kang Jae Jerry , Kim Jaehyun
Published: September 2021

PURPOSE: Rapid urbanization has witnessed a dramatic decrease in physical activity. The purpose of this research was to explore the vulnerable inactivity group influenced by urbanization in China.METHODS: Cross-sectional data from the 2015 China Health and Nutrition Survey were utilized. A total of 7,319 households, including 20,914 individuals within 12 provinces, were pooled. Seven types of physical activity were included in statistical testing. Community-level urbanization was measured on an urbanicity scale consisting of 12 dimensions. Cross-level logistic regression analysis was conducted to estimate the direct and interactive effects of individual socioeconomic statuses and community-level urbanization on a leisure time physical activity (LTPA). After removing incomplete responses, 8,617 samples were selected for the statistical analyses.RESULTS: Community-level urbanization was positively related to participation probability in the LTPA. With an increase of one standard deviation (SD) in the level of urbanization, the odds of participating in the LTPA increased by approximately six times in the most urbanized areas compared with the least urbanized areas. The effect of employment status on the probability of participation in the LTPA differed across the levels of urbanization in each community. For white-collar workers who resided in the most urbanized communities, the odds of participating in the LTPA decreased by approximately 46% compared to their peers in the least urbanized communities.CONCLUSIONS: Community-level urbanization should be addressed when developing interventions and health policies to promote physical activity during leisure time, especially for individuals who are white-collar workers living in urbanized communities.

Published: September 2021

PURPOSE: The purpose of this study was to compare thigh muscle activities and muscle co-activation when performing squats, wall squats, and Spanish squats on stable and unstable ground.METHODS: Twenty-two healthy male subjects (age: 22.50±2.70 years, height: 178.72±6.04 cm, mass: 76.50±6.80 kg, body mass index: 24.00±2.10 kg/m2, and Godin activity questionnaire: 56.30±24.10) voluntarily participated in the study. All of the participants performed three different squat exercises on the floor and the BOSU ball with an electromyograph attached to each participant’s quadriceps (rectus femoris, RF; vastus lateralis, VL; and vastus medialis, VM) and hamstrings (biceps femoris, BF; semitendinosus, ST; and semimembranosus, SM). Repeated measures of analysis of variance were utilized to compare muscle activity during the three squats exercises by floor type.RESULTS: RF (p<.001, η2=.689), VL (p<.001, η2=.622), and VM (p=.002, η2=.375) showed significant differences between exercises. Spanish squats yielded greater BF activity than did wall squats (p=.018, η2=.269). ST yielded greater muscle activity with the BOSU ball than on the floor (p=.018, η2=.269). Finally, there was a significant ground exercise interaction effect on the co-activation, showing greater muscle co-activation with Spanish squats on the BOSU ball compared to squats, squats on the BOSU ball, and wall squat on the BOSU ball.CONCLUSIONS: The findings of this study indicate that Spanish squats could be an effective exercise option for the facilitation of RF, VL, VM, and BF muscle activation. In particular, performing Spanish squats on an unstable surface could be useful for patients who need to improve their quadriceps muscle activation.

MORPHO-AGRONOMIC CHARACTERIZATION AND GENETIC DIVERSITY IN PEPPERS (Capsicum spp.)
Authors: SILVA MAYARA RODRIGUES E , SILVA RAIMUNDO NONATO OLIVEIRA
Published: September 2021

ABSTRACT Peppers and bell peppers (Capsicum spp.) are vegetables that have wide genetic variability, as well as a wide range of applications. Studies on genetic diversity help to understand the existing variability and the conservation of genetic resources, allowing breeders to select superior genotypes that meet the needs of breeding programmes. This study aimed to evaluate the genetic diversity among 15 Capsicum genotypes based on morpho-agronomic descriptors and through the Ward-MLM (Modified Location Model) procedure, as well as to indicate the most promising genotypes for breeding programmes. The research was conducted in an experimental area using a randomized block design, with three replications, using nine qualitative descriptors and ten quantitative descriptors. Analysis of variance was performed, and means were subsequently grouped by Scott-Knott’s method. There was a significant difference between genotypes for all traits evaluated, making it possible to select promising genotypes. According to the Scott-Knott grouping test, the number of seeds per fruit had the largest number of groups, with eight distinct groups, while plant height had only two groups. The genotypes GEN18 and GEN21 had the highest average values for fruit wall thickness and thus are indicated for the preparation of sauces. The genotypes GEN14 and GEN16 were the most promising for use for ornamental purposes. The Ward-MLM method made it possible to differentiate C. annuum L., C. baccatum L., C. chinense Jacq., and C. frutescens L. into different groups, and is thus a useful tool to detect genetic divergence.

ABSTRACT Garlic is a vegetable that has a high economic importance for Brazil. However, despite increases in garlic bulb production in the last years, Brazil is still dependent on imported garlic to meet the national demand. Thus, proper management practices and the use of virus-free clove-seeds are promising alternatives to ensure a high productivity and profitability. Thus, the objective of this work was to evaluate production characteristics and profitability of conventional and virus-free garlic crops as a function of different clove-seed sizes and plant spacings. Two experiments were conducted simultaneously, using virus-free and conventional garlic plants in Portalegre, state of Rio Grande do Norte, Brazil, in a randomized block experimental design, with four replications. The treatments were arranged in split-plot, with the clove-seed size (large and small) in the plots, and the spacing between plants (7.5, 10.0, 12.5, and 15.0 cm) in the subplots. The combination between the use of virus-free clove-seeds, large clove-seed size, and spacing of 12.5 cm between plants resulted in the highest commercial bulb yield and net income, R$ (BRL) 85,151.00 ha-1. The use of large clove-seeds and spacing of 7.5 cm between plants are recommended for conventional garlic crops.

ABSTRACT This work aimed to evaluate the physiological and biochemical changes resulting from controlled deterioration in different lots of sunflower seeds. Two sunflower seed lots of the cultivar Hélio 253 were subjected to simulated deterioration, using the accelerated aging test methodology (41 °C and 100% RH) for 0, 48, 72, and 96 h. Then, the seeds were subjected to the tests of germination, first germination count, seedling length and dry matter, emergence, accelerated aging, electrical conductivity, and total seedling length. The antioxidant activity was evaluated through the enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), and peroxidase (POX) at 0, 2, 4, and 6 days after sowing. Deterioration caused a reduction in the germination and vigor of the seeds, mainly in the lot with lower initial vigor and for the longest exposure times (72 and 96 h). For both lots, reductions in SOD activity and increases in POX and APX were observed during seed germination, mainly after 48 h of exposure to aging deterioration. Peroxidase enzymes are activated in deteriorated and non-deteriorated sunflower seeds, mainly after two days of germination.

Published: September 2021

ABSTRACT Caryocar brasiliense Camb. is a typical species from the Cerrado that represents a relevant income for the population where the fruit is produced. The ocorrence of insect pests provokes damage in the fruit and making its commercialization unfeasible. Then, this study aimed to identify the pest insect the fruit and the pit; to compare the morphological features of the fruit and pit and the damage caused by insects among mother plants and their origins and correlate the fruit and pit morphological features with the damage caused by the insects. Three different origins were evaluated, 12 mother plants by origin and ten fruit by mother plant. All the fruit were opened, checked for the insect damage and the fruit and pit morphological variables were determined. The insects that caused damage to the pequi embryo were identified as Carmenta sp. (Lepidoptera: Sesiidae) and Amblycerus sp (Coleoptera: Chrysomelidae). The probability analysis showed significant effect on the mother plants and origins for the percentage of fruit and pit attacked where the location of Laje Velha obtained the lowest rates of the insect attack. The fruit and pit of the Fruta de Leite were bigger and heavier than the others, while the correlations among the predation rate and the other morphological variables of the fruit and pit were not significant. Amblycerus sp. and Carmenta sp. may be considered potential pests of pequi, with the risk of compromising the pequizeiro populations and the regional economics.

ABSTRACT Water scarcity is one of the main problems in the Semiarid region of Brazil, which can be mitigated by water resource management strategies. The objective of this work was to classify waters of a watershed in the Semiarid region of Brazil and select the water attributes that most affect the quality of waters used for irrigation (QWI), using multivariate statistics. The study area was the Riacho da Bica watershed, which is between the municipalities of Portalegre and Viçosa, Rio Grande do Norte, Brazil. The QWI was determined using water samples from 15 collections carried out from 2016 to 2018, in five specific points of the watershed, starting in the spring and following the water course. The water attributes evaluated were: electrical conductivity (EC), potential hydrogen (pH), and sodium (Na+), potassium (K+), magnesium (Mg2+), calcium (Ca2+), carbonate (CO32-), chloride (Cl-), and bicarbonate (HCO3-) contents. The water quality data were subjected to multivariate statistics through factorial analysis (FA) and principal component analysis (PCA). The application of multivariate statistics through FA-PCA generated four principal components. The attributes that most explained the QWI variation were potassium, calcium, and pH for Factor 01, and sodium and RAS for Factor 02. The watershed waters were classified as low risk of salinity and medium risk of sodicity (C1S2) for irrigation purposes.

ABSTRACT This study was conducted with the objective of evaluating the quantum yield, photosynthetic pigments and biomass accumulation of mini watermelon cv. Sugar Baby, under strategies of irrigation with saline water and potassium fertilization. The experiment was conducted in a randomized block design, in a 8 × 3 factorial scheme, with three replicates, corresponding to eight strategies of irrigation with saline water applied at different phenological stages of the crop (control - irrigation with low-salinity water throughout the crop cycle, and salt stress in the vegetative, vegetative/flowering, flowering, flowering/fruiting, fruiting, fruiting/ fruit maturation and fruit maturation stage) and three potassium doses (50, 100 and 150% of the recommendation). The dose of 100% corresponded to 150 mg of K2O kg-1 of soil. Two levels of electrical conductivity of water were used: 0.8 and 4.0 dS m-1. Irrigation with water of 4.0 dS m-1 continuously in the vegetative and flowering stages increased the initial fluorescence and decreased the quantum efficiency of photosystem II of mini watermelon fertilized with 100 and 150% of K recommendation. Fertilization with 50% recommendation did not interfere in the fluorescence parameters of the mini watermelon, regardless of the irrigation management strategy. Chlorophyll a synthesis is inhibited by salt stress in the vegetative/flowering, flowering, flowering/fruiting, fruiting/maturation stages, as well as for total chlorophyll, except for the flowering stage. Application of 4.0 dS m-1 water in the flowering, fruiting/maturation and maturation stages promoted greater biomass accumulation in mini watermelon.

Published: September 2021

Abstract The purpose of the study was to develop and present validation evidences for a managerial competence mastery scale in the context of public management. The development of the initial instrument for data collection was based on literature analysis, and on theoretical and semantic validation made by judges, in addition to a pre-test. The questionnaire was electronically answered by 447 professionals—managers and non-managers—that belong to different public companies that works at the state level, engaged in technical assistance and rural extension. The results of exploratory factorial analysis presented signs of validity and reliability, indicating thirty competency items that were grouped into three factors: contribution for strategy, public service rendering and team management. As conclusion, the evidence indicates the validity of the scale to measure the managerial competence mastery, contributing to the evolution of managerial studies and increasing the reliability thereof. Additionally, the identified competencies reinforce the role of the managers in the alignment and management of organizational strategy, they indicate the existence of common characteristics of managers that work in different organizations and also demonstrate the adequacy of this instrument to the public sector reality. Finally, the use of the scale is suggested in other research contexts in order to confirm its structure and generalization potential.
Search threshold values of future liver remnant function and volume for extensive resections in children
Authors: Akhaladze D. G. , Rabaev G. S. , Merkulov N. N.
Published: September 2021

Aim. To evaluate the relationship between the future liver remnant volume and function and determine the possible threshold values of these parameters for predicting posthepatectomy liver failure in children.

Methods. Data of 57 patients who underwent major hepatectomy from July 2017 to February 2021 were retrospectively analyzed. Before surgery all children underwent the CT-volumetry and 99mTc-Mebrofenin hepatobiliary scintigraphy. The threshold values for the future liver volume and function were considered 25%, and 2.7%/min/m2 , respectively. After surgery the ISGLS and 50–50 criteria for posthepatectomy liver failure were assessed. The principal components method was used to identify risk factors for its development. The correlation analysis included the maximum value of total bilirubin after hepatectomy, as well as the values of total bilirubin, albumin, urea, prothrombin index, international normalized ratio and platelets on the postoperative day 5.

Results. The posthepatectomy liver failure was observed in 2 patients: grade B developed in a patient with FLR-V 43%, FLR-F 1.8%/min/m2 , grade A in a patient with FLR-V 16.5% and FLR-F 4.78%/min/m2 . A significant statistical relationship of average strength was revealed between the indicators of FLR-F and FLR-V (Pearson η = 0.409; p < 0.01). However, direct pairwise comparison did not reveal the relationship between future liver remnant volume, function and the laboratory parameters. The principal components analysis showed that during the postoperative period, the prothrombin index and international normalized ratio value were the most sensitive to the large volume of the liver parenchyma loss. The threshold value of FLR-F (3%/min/m2 ) was calculated. The decrease below this value can lead to posthepatectomy liver failure, which will manifest as a hemostasis disorder.

Conclusion. Planning a one-staged hepatectomy not only the future liver remnant volume should be taken into account, but also its function. The threshold for future liver remnant volume in children is below the generally accepted level 25%. To perform one-stage hepatectomies in such patients, the FLR-F must be at least 2.7%/min/m2 . The future investigations in this field is waranteed.

Methods to improve mechanical characteristics of ceramics on the basis of zirconium and hafnium diborides (Review)
Authors: Portnova Ekaterina N.
Published: September 2021

This paper describes the main methods for improving the mechanical properties of ceramic materials based on zirconium and hafnium diborides, such as strength and crack resistance. Particular attention is paid to the influence of the sintering method, as well as additives introduced into the powder composition, in particular hard fibers, second-phase powder particles and “whiskers”, on the mechanical characteristics of the ceramics. On the basis of the analysis of literature data, it is shown that the spark plasma sintering (SPS) method allows to obtain ceramic samples with increased mechanical characteristics due to their high density and low defects. The addition of silicon carbide filamentous crystals or fibers to the ceramics can increase the crack resistance of the sintered material up to 6.0–8.5 MPa×m1/2. These conclusions can be useful in the development of ultra-high-temperature ceramic materials.

Zbog sve većeg broja starijeg stanovništva povećava se i broj osoba koje žive u statusu umirovljenika. Kako bi osobe postigle što bolju kvalitetu života i očuvale svoj potencijal te i u starijoj dobi nastavile davati doprinos društvu, potrebno je kontinuirano provoditi istraživanja o prilagodbi na umirovljenje. Fokus ovoga istraživanja usmjeren je na dobivanje jasnijeg uvida u prilagodbu starijih osoba na umirovljenje s obzirom na samoprocjenu zdravlja i percepciju socijalne podrške te na mogućnost prepoznavanja faktora kojima bi se moglo djelovati u poboljšanju loše prilagodbe na umirovljenje. Istraživanje je provedeno u jesen 2019. godine, a uključivalo je 208 osoba oba spola starijih od 65 godina, bez tjelesne invalidnosti ili teških tjelesnih, kognitivnih ili mentalnih bolesti, koje žive u Domu umirovljenika u Bjelovaru i koji su korisnici gerontoloških centara u Zagrebu. Razlike u prilagodbi na umirovljenje s obzirom na samoprocjenu vlastitog zdravlja i percepciju socijalne podrške razmatrane su prema Atchleyevom (2000) modelu prilagodbe na umirovljenje. Dobiveni rezultati potvrđuju konceptualne pretpostavke ranijih istraživanja te ukazuju na pozitivniju orijentiranost prema životu u mirovini ispitanika s boljim rezultatima u samoprocjeni vlastitog zdravlja i percepciji socijalne podrške. Razlozi tomu mogli bi biti bolje zdravlje koje pojedincu pruža mogućnost da ostane više društveno aktivan i bude usmjeren na svoju ulogu umirovljenika, a stalna socijalna podrška pomaže u postizanju pozitivnih iskustava tijekom prilagodbe na umirovljenje. Rezultate predstavljene u ovom radu treba promotriti i u kontekstu otvaranja prostora za daljnja istraživanja, ali i za nove rasprave u području zdravstvenih i socijalnih pitanja budućih i trenutnih umirovljenika.

RE-CONNECTING WITH THE NATURE: A DESIGN FOR BİLECİK CITY BOTANIC GARDEN
Authors: KAYMAZ Işıl , BAKİ Ecem , SARIHAN Faruk , PERÇİN Halim
Published: September 2021

Aim: This study aims to determine the design dynamics for botanic gardens within the framework of landscape design. It is also aimed to emphasize the importance of unique characteristics of botanic gardens and to raise awareness on their scientific, education and social roles. Method: The methodology of this study is based on analysis of the literature on design of botanic gardens and worldwide examples; synthesis of these data through a landscape project for a proposed botanic garden in Bilecik, Turkey; and finally, evaluation of overall findings in order to determine the dynamics that influence design of a botanic garden. Results: Diversity of the plants proposed in the design scheme was determined based on the ecological conditions of the site and the budget. The design also proposes places for recreational purposes that will help to support both physical and mental health of the visitors and for educational purposes which will raise the public awareness. However, it is also concluded that spatial design, solely, is not a determining factor for realizing their missions. The effective operational management of a botanic garden is important for sustaining the conservation and the education missions. Conclusion: The quality and the functionality of a botanical park cannot be solely determined through the design process although spatial characteristics of a site have a considerable influence on the design scheme and content. The effective design and implementation of operational program of plant conservation, educational and recreational activities are essential in order to sustain the identity of any botanic garden.
Image Analysis to Quantify Coral Bleaching Using Greyscale Model v1
Authors: Mclachlan Rowan , G Grottoli Andrea
Published: September 2021

This protocol outlines a method of quantitatively measuring the degree of bleaching of a coral colony non-destructively in the field using image analysis. Previous studies have shown that mean intensity grey (MIG), also known as percent whiteness, is highly correlated with chlorophyll a and Symbiodiniaceae density (Chow et al. 2016, Amid et al. 2018), and therefore can be used to quantify the bleaching intensity of a coral colony. Color analysis can be done using digital photographs of live coral colonies either in situ (e.g., Maguire et al. 2003) or ex-situ in the lab (Amid et al. 2018; this protocol). Photographs must be taken prior to any preservation or processing of tissue, such as freezing, use of preservatives or fixatives, airbrushing etc., to ensure no alteration of the original coral color occurs. In this protocol, corals are photographed in front of a white reference standard and the resulting color images are subsequently converted to 8-bit greyscale and analyzed. There are two steps to this protocol: 1) Photographing live coral fragments 2) Image analysis of mean grey value This protocol was written by Dr. Rowan McLachlan and was reviewed by Dr. Andréa Grottoli. Acknowledgments I would like to thank Dr. Eugene Katrukha for kindly taking the time to teach me this method, and providing me feedback on how to produce higher quality images for analysis.

Published: September 2021

Calculations of the centrifugal machines critical frequencies of the rotors are currently carried out on the basis of the finite element method using multi-functional software as same as ANSYS and other similar, that work with finite elements of the three-dimensional type, as well as some specialized computer programs working with the beam-type finite elements. Anyway, the finite element method is used. But in this case an user needs a lot of time for prepation of the initial data. Therefore, this article presents a calculation of the critical frequencies of the rotor of a centrifugal fuel pump of a liquid-propellant engine based on its discrete model. This calculation also includes an algorithm of results clarification. This model has been verificated by comparing the critical frequencies obtained in calculations based on the finite element beam model and discrete model with using the algorithm of results clarification and without it.
