Authors: Dias Karina Gualqui Marchi , Dietrich Karyne Ansante , Pedro Marcela Corrêa , De Meneses Eli Cristiano
Published: June 2021

A Hipertensão Arterial é uma doença crônica, com origem por vários fatores, hereditários, idade, raça, hábitos alimentares e mobilidades físicas, provocando anomalias nos vasos sanguíneos, provocando uma alteração dos níveis de pressão arterial e muitas vezes provoca crises abruptas das quais retiram o paciente da homeostasia. As alterações dos níveis de pressão, obstruções arteriais, contribuem ao aparecimento de crises hipertensivas, infarto agudo do miocárdio, insuficiência cardíaca congestiva e AVC. Uma das classes indicadas para tratar esta patologia é a classe medicamentosa dos IECA’s, inibidores de angiotensina I e II. O medicamento desta classe mais utilizado é o captopril. Entretanto apesar do medicamento possuir uma forma farmacêutica desenvolvida e fabricada para administração via oral, ele vem sido utilizado a muitos anos pela via sublingual em emergências hipertensivas. Este segmento dá-se devido a sua eficácia significativa através desta via de administração. Após inúmeros testes realizados, pesquisadores acreditam que o medicamento tem efeito superior em relação ao tempo de eficácia, quando comparado a administração do mesmo por via oral.
Non-Resonant Reaction Rates of 13C(Î±,n)16O and 22Ne(Î±,n)25Mg reactions in AGB Stars
Authors: Talib Lana , A. Selman Ahmed
Published: June 2021

Both 13C 16O and 22Ne 25Mg reactions perform a cosmic role in the production of neutrons in AGB stars, which significantly contributes to the nucleosynthesis via the s-process. The astrophysical S-factor for both reactions has been calculated in this research, utilizing EMPIRE code and depending on two parameter sets for the optical potential: McFadden and Satchler (MFS), and Avrigeanu and Hodgson (AH) for the non-resonant region of the spectrum, and over a temperature range . The extrapolated S-factor at zero energy is derived to be  and  for 13C 16O,  and  for 22Ne 25Mg from using MFS and AH parameter sets respectively, and they show a reasonable agreement with the most recommended value. The differences in the S-factor, S(E), values obtained from these two adopted parameters set, were attributed to the variations of the real potential term's diffuseness parameter that affecting the reaction cross section, hence S-factor, and specifically at low energy region. Moreover, the present results imply an influential enhancement of the rates by the electron shielding effect at the low-temperature region  in which 13C 16O reaction activated, and especially on 22Ne 25Mg reaction. In addition, for both adopted reactions and overall selected temperature range, the reaction rates using  values based on MFS showed acceptable results with other previous compilations and reference libraries. While that obtained from AH exceed all other compilations even though the resonance contributions are currently unconsidered.
An Emerging Fault Related Fold (Mahad Anticline) and its Morphotectonic Interpretations in Northern Iraq
Authors: Hamdon Alaa N. , Znad Rabeea Khalaf
Published: June 2021

In this study, morphotectonic analyses were prepared for an anticline existing to the north of Maqloub Anticline and extends toward north - south approximately, which is unfamiliar in relation to the major extension of the anticlines in the region. The study involves a structural interpretation of the anticline's origin and its relation with the faulting in the foreland zone in this area, specifically in foothill zone, because of the major fracture that is found adjacent and parallel to the axis of this anticline.

The visual interpretation is the major tool used to determine the features of this anticline. Moreover, some facilitating remote sensing technologies, such as digital processing of satellite images and Digital Elevation Model data, were utilized to verify the shape of this geological feature. 

The origin of the fold was discussed through its relationship to the    associated fault within the general tectonic framework and the surrounding areas. This study addresses the tectonic mechanism of the anticline as a fold-related fault mechanism.

As a result, and through the compilation of the above interpretations, a final geological map was prepared for this anticline, along with a 3D model demonstrating its mechanism of folding. Proposed names were given to the anticline and the fault, which are Mahad Anticline and Mahad Fault , according to the name of their nearest town (Mahad Town).

Authors: Al-Naji Ahmed Jawad , Jasim Hasan Kattoof , Tamar-Agha Mazin Y. , Al-Shammery Thamer Abaas
Published: June 2021

This paper concerns the study of ripples that occur on the windward of Barchan dunes from the dunes field of Najaf governorate, Iraq. These dunes consist mainly of sand sediments with variable sizes, including medium, fine, and very fine sands. Quartz represents the major light mineral in the Najaf Dunes sand. The prevailing wind direction in the study area is NW-SE. The major ripple crest series of every pattern are oriented perpendicular to the NW-SE wind direction, whereas imbricated ripple groups within the troughs of the preexisting ripples are created by the WSW-ENE wind trend. These ripples tend to be formed by shortened ripples that occupy the troughs of the prolonged series. All crests of the ladderback ripples are oriented at right angles to asymmetry ripples. The ladderback ripples were noticed from fine to very fine- grained sediments, which consist mainly of quartz. The wavelength of the ladderback ripples ranges from 2 – 4 cm, while they are 0.1 – 0.2 cm in height. The occurrence of ladderback ripples within an aeolian environment indicates a variety of wind directions, which influenced the arrangements of the crest ripples.

Authors: Sunarti Sunarti , Ferdinandus Meske
Published: June 2021

The research on laboratory wastewater treatment using Eucheuma cottoni as biosorbent was carried out to find the right composition of wastewater and algae that is effective in reducing the pollutant contained in the laboratory wastewater. The dosages of biosorbent were varied with 100 gr, 200 gr, and 300 gr  were added into 1000 ml of wastewater mixed with 1000 ml of sea water. Chemical parameters such as  pH, COD and NH3 and physical parameters such as odor, color, turbidity were analyzed and in accordance with contact time parameters of H1 (1 hour), H2 (12 hours) and H3 (24 hours). The percentage of pollutant reduction in wastewater was calculated  by comparing the value before treatment with the value after treatment to get the right composition of the biosorbent to get the highest reduction percentage. The percentage of pollution reduction in the value of each parameter, showed that the third treatment with 300 gr of biosorbent was the most effective condition in reducing the pollutant contained in laboratory wastewater with the final outcomes were pH 6.67 COD 74.67 mg / L, NH3 0.731 mg / L, scale 1 color 40 PtCo and turbidity 37.6 NTU. The results are  in accordance with Wastewater Quality standards Permen LH No. 5 of 2014.

Authors: Darwis Mochammad
Published: June 2021

Many cases of fire due to electrical short circuit facilities or inadequate electrical maintenance, require technology in the field of preventive maintenance. Educational materials and knowledge regarding the prevention and handling of damage and the dangers resulting from abnormal heat, must be taught in the practice class, in particular the electrical installation practice. The use of photo infrared thermography to analyze the distribution of excess heat (overheating) at the cable connection points and the constituent electrical components is a new necessity. The still expensive thermal camera led to an inexpensive prototype but still had the same result. The infrared camera prototype was made from the M5Stack microcontroller module and the AMG8833 infrared thermal sensor. The camera was used to check the heat patterns that occured in electrical and mechanical equipment during the operation. The temperature data recorded from the AMG8833 sensor were in the form of an array of data measuring 8x8 pixels which then were proceeded using an interpolation technique to get an even bigger size, 64x64 pixels. The temperature data were presented in a form of certain colors which represented the measured temperature. The prototype results were compared with the standard HT-02 thermal camera resulting in 0.001% of error.

Authors: Hendra Surani
Published: June 2021

Energy alternatives are starting to get attention due to the depletion of petroleum sources as the current fuel. One of them is biodiesel. Microalgae has the potential to produce fat that can be proceed into biodiesel. This study aims to find the shaking time and the suitable solvent with the extraction of microalgaes, namely Naviculla Salinicola and Chlorella Vulgaris fatty acids with various solvents, namely hexane, methanol and chloroform. Each microalgae can affect different cell walls that resulting in different extraction materials. The results showed that fatty acids Chlorella Vulgaris and Naviculla Salinicola were extracted the most with hexane. The fat content extracted from Chlorella Vulgaris with three solvents were 10.56% for hexane, 6.79% for  methanol and 5.99% for chloroform. For the extraction of Naviculla salinicola with hexane solvent yielded 4.37% fat, while with choloroform was 2.99% and with methanol was 2.48%. The increase in processing time resulted in an increase in the equivalent of fat extraction in both types of microalgae with the highest one was obtained at the five-hour shaking time.
Laboratory solid waste from practical activity as activated carbon precursor for reducing methylene blue in the laboratory wastewater
Authors: Puari Aninda Tifani
Published: June 2021

Activated carbon (AC) from agricultural waste has become one promising way to produce AC regarding to low price of the precursor and its effect to environment. In this research, the solid waste from the basic biology practical in UPT. Basic and Central Laboratory, Andalas University (Unand) was utilized as the precursor for producing low price AC. The activation was done by chemical activation using three different activating agents which were zink chloride (ZnCl2), phosphoric acid (H3PO4), potassium hydroxide (KOH). The carbonization process was done at temperature of 700°C. The precursor and three different AC after activation were characterized using fourier-transform infrared spectroscopy (FT-IR) to examine  the functional group and scanning electron microscope (SEM) to observe the pores structure. The adsorption efficiency (AE) of each AC on methylene blue (MB) contained in laboratory wastewater was examined through adsorption process with retention time of 30 minutes at room temperature and neutral pH. SEM analysis showed that the three activating agents were resulting in higher surface area and more pores were formed. The highest AE of MB from laboratory wastewater for each AC were 97,5 %, 96,31%, and 90,79 for KOH, , ZnCl2, and H3PO4, respectively. Meanwhile, the highest adsorption capacity was achieved by AC through KOH activation with 0,003 mg/g
Besicovitch Pseudodistances with Respect to Non-Følner Sequences
Authors:   Department of Software Science Tallinn University of Technology, Capobianco Silvio , Guillon Pierre ,   CNRS, Aix-Marseille Université Institut de Mathématiques de Marseille
Published: June 2021

The Besicovitch pseudodistance defined in [1] for biinfinite sequences is invariant by translations. We generalize the definition to arbitrary locally compact second-countable groups and study how properties of the pseudodistance, including invariance by translations, are determined by those of the sequence of sets of finite positive measure used to define it. In particular, we restate from [2] that if the Besicovitch pseudodistance comes from an exhaustive Følner sequence, then every shift is an isometry. For non-Følner sequences, it is proved that some shifts are not isometries, and the Besicovitch pseudodistance with respect to some subsequences even makes them discontinuous.
Self-Stabilizing Distributed Algorithms by Gellular Automata
Authors:   The University of Tokyo, Hongu Taiga , Hagiya Masami ,   The University of Tokyo
Published: June 2021

Gellular automata are cellular automata with the properties of asynchrony, Boolean totality and noncamouflage. In distributed computing, it is essential to determine whether problems can be solved by self-stable gellular automata. From any initial configuration, self-stable gellular automata converge to desired configurations, as self-stability implies the ability to recover from temporary malfunctions in transitions or states. This paper shows that three typical problems in distributed computing, namely, solving a maze, distance-2 coloring and spanning tree construction, can be solved with self-stable gellular automata.

Although there is substantial evidence on the association between physical activity and self-rated health among older adults globally, there is a paucity of findings on this topic for the aging Indonesian population. The present study was conducted to investigate the association between self-reported physical activity and self-rated health among older adults in Indonesia. The data used were from the fifth wave of the Indonesian Family Life Survey (IFLS). A multilevel regression approach was used for analysis. A sample of 1,813 older adults (aged 60 and over) within 311 communities was used in the study. Self-reported physical activity measured by time spent walking was the independent variable, and self-rated health was the dependent variable. The analysis was adjusted for gender, age, education level, marital status, religiosity, retirement status, neighborhood safety, extroversion, and subjective poverty. The results revealed that increased physical activity was consistently associated with better self-rated health in both unadjusted (β=0.04, p<0.05) and adjusted (β=0.06, p<0.01) models. To improve public health in Indonesia, primary health care professionals, health policymakers, and other health promoters should consider including physical activity in health policies and encourage older individuals to engage in regular physical activity.

Published: June 2021

W pracy przedstawiono ocenę aktualnych działań promocyjnych w Kielcach oraz w gminach miejsko-wiejskich powiatu kieleckiego wraz ze wskazaniem głównych problemów w zakresie funkcjonowania w nich promocji turystycznej. Do oceny przeprowadzonej w 45 obiektach turystycznych reprezentujących gminy zastosowano autorski system punktacji, uwzględniając 7 aspektów i 21 podkategorii promocyjnych. Pozwolił on na obiektywną ocenę działań w zakresie promocji turystyki w jednostkach administracyjnych. Wyniki oceny syntetycznej wskazują, że najwyższą liczbę punktów, poza gminą Kielce, uzyskała gmina Chęciny, która posiada utrwaloną tradycję promowania turystyki i ma w tym zakresie duże osiągnięcia. Stwierdzono również wysoką pozycję gmin Nowa Słupia i Bodzentyn, co wynika z położenia na ich obszarze atrakcji krajoznawczych o znaczeniu krajowym. Z kolei gminy miejsko-wiejskie ustanowione w ostatnich latach w prezentowanej ocenie uzyskały najniższą punktację, co może być efektem małych doświadczeń w podejmowaniu profesjonalnych działań promocyjnych oraz skromniejszych możliwości finansowych.
DEMOGRAPHIC CHANGES AND THEIR IMPACT ON URBAN ECONOMIC BASE THE CASE OF TOWNS FROM THE ŁÓDŹ VOIVODESHIP
Authors: Guz Jagoda
Published: June 2021

Structural transformations that have been taking place in Poland since the 1990s triggered important changes in demographic and economic urban structures. Poland’s opening to global processes brought Polish society to the stage of modern demographic development which has produced changes in, among others, vital statistics and spatial mobility of the country’s residents. Systemic and structural transformation of the country at the early stages has significantly undermined its economy, in particular, in urban centres. Very much needed restructuring of urban economies resulted in the closure or bankruptcy of many enterprises. The economic function of towns and cities and their demographic structure have changedprofoundly, exerting a mutual impact on each other. The paper is based on the assumption that there is a relationship between demographic changes in towns and cities and the urban economic base. Its goal is to identify the impact exerted by demographic changes on the economy of investigated towns. The problem is illustrated with cases of towns and cities in Łódź Voivodeship (territorial units with the city status as on 1 January 2018). The research time frame spanned 1995 and 2017.
Frequência lexical dos ataques ramificados CCV em Português Brasileiro: comparando a fala adulta, a fala dirigida à criança e a fala infantil nos corpora FI e FDC
Authors: Toni Andressa
Published: June 2021

Este artigo apresenta à comunidade linguística o Corpus de Fala Infantil (Corpus FI) e o Corpus de Fala Dirigida à Criança (Corpus FDC), uma nova base de dados voltada aos estudos sobre Aquisição da Linguagem. Estes corpora foram compilados a partir do banco de dados longitudinais de Santos (2005) utilizando as ferramentas computacionais de Benevides e Guide (2016). Os corpora consistem em uma lista de frequências contendo informações fonológicas (transcrição fonológica, transcrição acentual, estrutura silábica, categoria acentual) e morfológicas (categoria lexical e lema) das palavras coletadas na fala de 3 crianças (Corpus FI) e de seus cuidadores (Corpus FDC). Para divulgar esses corpora de acesso livre, este artigo i) descreve a metodologia utilizada em sua compilação e manuseio; e ii) oferece um exemplo sobre como estes corpora podem contribuir às pesquisas sobre o desenvolvimento linguístico infantil. Para tanto, comparamos as frequências segmental e prosódica das sílabas CCV (Consoante1+Consoante2+Vogal) na fala adulta, na fala dirigida à criança e na fala infantil demonstrando como a frequência do input influencia o percurso da aquisição fonológica. Os resultados apontam congruência na composição prosódica e segmental dos corpora, com CCV majoritariamente ocupando posições de saliência prosódica e apresentando concentração em sequências consonantais específicas. Dada a baixa frequência geral de CCV, baixo número de pares mínimos CV-CCV e existência de contextos de baixa transparência fonológica, defendemos que o input é um fator que contribui ao longo percurso de aquisição deste tipo silábico, que surge na fala infantil antes dos 2;0 anos e só se estabiliza entre 5;0-6;0 anos.

Comparative study for safety and efficacy of a novel folic acid formulation gel with 0.1% triamcinolone acetonide paste in experimentally induced oral ulcer
Authors: Rashid Sulthan Al , Rahman Syed Ziaur , Khan Saif
Published: June 2021

Objectives:

The objective of the present study was to evaluate the efficacy and safety of 0.1% novel folic acid gel in blunt dental instrument-induced oral ulcer in animal models (both rats and rabbits).

Materials and Methods:

The study was conducted in the Experimental Laboratory, Department of Pharmacology, Jawaharlal Nehru Medical College, Aligarh Muslim University. Animals were randomly divided into three interventional groups, namely Group 1 (folic acid gel), Group 2 (triamcinolone oromucosal paste) and Group 3 (control). We created a linear oral ulcer of 5 mm with the blunt dental instrument in both rats and rabbits. Each group consists of 10 animals (6 rats + 4 rabbits). Group 1 received test drug 0.1% novel folic acid gel formulated by us, Group 2 was positive control and received standard local drug 0.1% Kenacort triamcinolone oromucosal paste and Group 3 served as a negative control group where no treatment was given.

Results:

No untoward reaction was observed on the irritancy test. Kruskal–Wallis test applied for comparison of results. After 1 week of post-ulcer induction, there was a marked improvement in healing of oral ulcers in both Group 1 and Group 2, but more statistically significant healing was seen in Group 1 (folic acid gel). Both Groups 1 and 2 showed steady improvement in the healing of oral ulcers as compared to their pre-treated values and again were more marked in Group 1.

Conclusion:

Local folic acid gel supplementation was safe and had shown to augment oral ulcer healing in rats and rabbit’s animal models.

Published: June 2021

Lignin is one of the main constituents of lignocellulosic biomass, whose valorization is essential for an economically feasible biorefinery process scheme. In the present work, a hydrogen-free one step catalytic fractionation of woody biomass using commercial b-zeolite as catalyst in a flow-through reactor was carried out, leading to a maximum aromatic monomer yield of 20.5 wt.%. Birch, spruce and walnut shells were used and compared as lignocellulosic feedstocks. Relevant insights in the reaction mechanism were obtained through 2D HSQC NMR analysis, revealing that b-O-4 cleavage is catalyzed by the zeolite. To optimize system operation, a rate limiting step analysis was performed by using different reactor configurations. It was found that the system operated in a mixed regime where the rates of both solvolytic delignification and zeolite-based depolymerization/dehydration affect the net rate of aromatic monomer production. Oxalic acid addition was found to enhance monomer production at moderate concentrations by improving solvolysis; however, it caused structural changes to the zeolite leading to lower monomer yields at higher concentrations. Zeolite stability was assessed through catalyst recycling and characterization using NH3-TPD, XRD, N2 physisorption and TGA. Main catalyst deactivation mechanisms were found to be coking and leaching, respectively leading to larger pore size and lower concentration of acid sites.
Quantum Tunneling Characteristics in Monolayer Graphene Modulated by Multiple Electrostatic Barriers
Authors: Dakhlaouhi Hassen , Belhadj Walid , Wong Bryan
Published: June 2021

The transmission coefficient and electronic conductance of a graphene monolayer in the presence of multi-electrostatic barriers are theoretically investigated using the transfer matrix method (TMM). The transmission coefficient, conductance, and Fano factor are evaluated as a function of the number and width of the barriers, angle/energy of incidence, as well as the applied potential at each barrier. We find that the transmission coefficient presents a series of resonances that depends on the number and widths of the barriers. Furthermore, we show that the resonant states can be suppressed for larger incidence angles and barrier widths and tuned towards lower energies. Consequently, the proposed structure can be used to fabricate new optoelectronic devices based on (ON/OFF) states as tunable field-effect transistors.
Photocatalytic Activity of Diverse Organic Radical Anions: Catalyst Discovery Enables Cleavage of Strong C(sp2)–N and C(sp2)–O Bonds
Authors: Chernowsky Colleen , Chmiel Alyah , Wickens Zachary
Published: June 2021

Herein, we leverage electrochemistry to examine the photocatalytic activity of a range of structurally diverse persistent radical anions and find that many are effective electrophotocatalysts. These studies uncover a new electron-primed photoredox catalyst capable of promoting the reductive cleavage of strong C(sp2)–N and C(sp2)–O bonds even when reduction potentials hundreds of mV more negative than Li0 are required. We illustrated several examples of the synthetic utility of these deeply reducing but otherwise safe and mild catalytic conditions. Finally, we employed electrochemical current measurements to perform a reaction progress kinetic analysis that revealed that the improved activity of this new catalyst was a consequence of an enhanced stability profile.
How Stable Are 2H-MoS2 Edges Under Hydrogen Evolution Reaction Conditions?
Authors: Abidi Nawras , Bonduelle-Skrzypczak Audrey , Steinmann Stephan
Published: June 2021

MoS2, have emerged as a promising class of electrocatalysts for the production of H2 via the hydrogen evolution reaction (HER) in acidic conditions.The edges of MoS2 are known for their HER activity, but their precise atomistic nature and stability under HER conditions is not yet known. In contrast to other typical uses of MoS2 as a catalyst, under HER there is no external source of sulfur. Therefore, the sulfidation of the edges can only decrease under operating conditions and the thermodynamics of the process are somewhat ill-defined. Our results suggest that the 50%S S-edge may be active for HER via the Volmer-Tafel mechanism and is, despite a high H coverage, stable with respect to H2S release. At the 50%S Mo-edge, the adsorbed hydrogen opens the way for H2S release, leading to the 0%S Mo-edge, which was previously investigated and found to be HER active. HER being a water-based process, we also considered the effect of the presence of H2O and the in-situ formation of OH. For the 50%S Mo-edge, H2O is only very weakly adsorbed and OH formation is unfavorable. Nevertheless, OH assists the loss of sulfur coverage, leading to OH-based HER active sites. In contrast, OH is strongly adsorbed on the 50%S S-edge. By explicitly considering the electrochemical potential using grand-canonical density functional theory, we unveil that the Volmer-Heyrovsky mechanism on sulfur sites is still accessible in the presence of surface OH at the 50%S S-edge. However, the 50%S S-edge is found to be mildly unstable with respect to H2S in the presence of water/OH. Hence, we suggest that the 50%S S-edge evolves over time towards a 0%S S-edge, covered by surface OH that will block permanently the active sites.
Origins of Internal Regioselectivity in Copper-Catalyzed Borylation of Terminal Alkynes

Published: June 2021

Installation of a boron functionality into a more substituted carbon of terminal alkynes has been a challenging issue in chemical synthesis, since inherently Lewis acidic boron moieties, in principle, favor their attachment to a terminal carbon. Herein, we report on the highly internal-selective borylation of terminal alkynes under copper catalysis, wherein diminishment of boron-Lewis acidity and ligand-derived steric bulk around a copper center are the key to the success. In particular, the use of an anthranilamide-substituted boron moiety [B(aam)] is of high synthetic significance, because its properly diminished Lewis acidity enabled the internal regioselectivity and the Suzuki–Miyaura cross-coupling activity to be compatibly achieved. This method provided direct and universal approach to variously substituted branched alkenylboron compounds, regardless of electronic and steric properties of a substituent on terminal alkynes.

Authors: Pinchuk O.A.
Published: June 2021

This paper analyzes the one of the least developed areas of accounting research, such as accounting in the army. There are no works which have been devoted to the issue of analytical accounting of fixed assets in military units. In the conditions of a hybrid war in Ukraine, an effective accounting system in military units is required, due to the specifics of their organizational, economic and technological features, which would allow responding quickly to modern challenges. The article considers one of the most important areas of accounting for military units, namely, accounting for fixed assets, its analytical support. An effectively structured analytics structure should ensure the effective and timely execution of tasks assigned to military units in accordance with current legislation. Suggestions for building a rational model of organization of analytical accounting of fixed assets in military units are given. The following levels of analytical accounting in military units are proposed: by purpose of property, by places of storage, by technical characteristics, by funds of military camps and by relevant services. The components of accounting for missile and artillery armament of tanks (self-propelled artillery units, infantry fighting vehicles, armored personnel carriers, and other military equipment) have been separately identified. The construction of the analytical system took into account the specifics of the sphere of activity of the business entity, which determines the individual nature of information flows in the system of management analysis of production and economic activities of the institution.

Background: Obesity is common worldwide, especially in low- and middle-income countries. Aims: To update data on the prevalence of overweight, obesity and central obesity, and to measure incidence rates for such outcomes in adults living in the south-east of the Islamic Republic of Iran. Methods: We enrolled 9997 adults (aged 15–80 years) between 2014 and 2018 (phase 2); 2820 of whom had participated in phase 1 (2009–2011). Participants were examined for overweight, obesity, central obesity, diabetes, hypertension, low physical activity, and dyslipidaemia. Univariate and multivariate logistic regression models were used to determine the potential predictors of overweight, obesity and central obesity, and adjusted odds ratios (AOR) were obtained. Incidence rate of overweight, obesity and central obesity was reported among those who had none of these outcomes in phase 1. Results: The prevalence was 35.8% (37% men, 35% women) for overweight, 22.3% (16% men, 26.3% women) for obesity, and 31.1% (15.6% men, 41.2% women) for central obesity. The prevalence of overweight/obesity was significantly associated with age (AOR = 2.8–7.4), higher education (AOR = 1.7), female gender (AOR = 1.4), low physical activity (AOR = 1.3), smoking (AOR = 0.55) and opium use (AOR = 0.79). The prevalence increased from 33.3% to 35.8% for overweight and from 15.4% to 22.3% for obesity between phases 1 and 2. The incidence rate per 100 person-years was 5.5 for overweight, 4.7 for obesity and 2.9 for central obesity. Conclusion: Prevalence of overweight and obesity increased over 5 years. Middle-aged participants, women, and those with low physical activity were at higher risk for overweight/obesity.

Authors: De la Fuente Morales Claudia Guadalupe , Méndez Sánchez Fernando
Published: June 2021

El denominado Derecho a la Ciudad, parte de la premisa de que la población pueda recuperar los espacios urbanos que originalmente les corresponden y hacerlos nuevamente parte de su propia cultura, independientemente de los intereses del capitalismo salvaje. Desde el punto de vista de este derecho, se propuso un estudio de la Ciudad de Puebla, analizando su fundación, y la manera en que la población ha sufrido una planificación territorial muy específica, de la cual se desprenden ahora muchos de los problemas de violencia y conflictos sociales que se viven al interior de esta.  Se utilizaron los métodos inductivo, histórico y analítico, recurriendo a instrumentos nacionales e internacionales, con especial énfasis en estos últimos. Dentro de las principales conclusiones que se obtuvieron se debe destacar la necesidad de aplicar un protocolo para coadyuvar con el desarrollo del Derecho a la Ciudad en Puebla, que abarque tres aspectos: comunidad, delincuencia y ambiente.
violencia epistémica en las ciencias económicas: pandemia, confusión epocal y extravío en el mar caudaloso de los problemas públicos
Authors: Enríquez Pérez Isaac
Published: June 2021

En medio de la confusión epocal, se pretende reivindicar el ejercicio del pensamiento crítico en la ponderación de la epistemología propia de la teoría económica neoclásica. Los problemas económicos contemporáneos que gestan rupturas históricas, imponen desafíos teórico/epistemológicos a dicha teoría, y ésta —al encontrarse desanclada de ellos— no siempre brinda las respuestas pertinentes respecto al proceso económico que afecta al ciudadano de a pie. Al problematizar a la pandemia como un hecho social total dotado de sistemas complejos, se evidencia la resistencia de esta teoría al ejercicio de la interdisciplinariedad y al diálogo con otros campos del conocimiento en aras de privilegiar el estudio de la sociedad como totalidad.
