Authors: De la Fuente-G Joel , Verma Surendra P.
Published: May 2021

En este trabajo se presenta una síntesis de los principales datos de localización e identificación del total de 3,225 estructuras de origen volcánico en un área de â‰ˆ141,000 Km2, que corresponde a la parte centro-occidental del Cinturón Volcánico Mexicano (CVM). Los cerros son las estructuras más comunes en dicha área (â‰ˆ73%). La mayoría de los aparatos volcánicos (â‰ˆ60%) es de composición máfica, predominando los basaltos. Una gran parte de estas estructuras (â‰ˆ80%) se encuentra entre los 2,000 y 3,000 m de altura con respecto al nivel del mar. Las máximas concentraciones de aparatos se localizan al occidente del Valle de México y en la porción noroccidental del Estado de Michoacán (81 - 120 estructuras por cada 1,000 Km2). Dentro de esta última región, existe un área con más de 120 estructuras por cada 1,000 Km2. El frente Volcánico del CVM varía en distancia con respecto a la Trinchera Mesoamericana (TMA) desde â‰ˆ100 Km en el NW hasta â‰ˆ250 Km en el SE del área en estudio. Los límites norte y sur del CVM se han precisado en términos del último apartado volcánico que existe en el área en estudio.
Implicaciones de los datos paleomagnéticos sobre la edad de la Sierra de Chichinautzin, cuenca de México
Authors: Urrutia-Fucugauchi Jaime , Martin del Pozzo Ana Lilian
Published: May 2021

La polaridad geomagnética normal documentada para el Grup Chichinautzin correlacionada con el Cron normal Brunhes de la Escala de Geomagnética de Polaridades, lo que indica una edad más joven que 0.78-0.79 Ma. Para estimar la edad de inicio de la actividad y su distribución temporal y espacial se requiere sin embargo de estudios más detallados de caracter multidiciplinario (geocronológicos y de estratigrafía volcánica). Implicaciones sobre el cierre del drenaje y formación de la cuenca deben también de analizarse críticamente. Las unidades muestreadas provienen de la parte más joven (expuesta) de la Sierra (considerada probablemente como más joven de 40-60,000 años, dentro del rango de fechaiento por C-14) y por lo tanto no representa un muestreo sin sesgo representativo para el Grupo. Ello resalta la necesidad de contar con datos de muestras del subsuelo, así como de las secciones basales de la sierra. Resultados preliminares de la porción sureste de Chichinautzin (hacia el valle de Cuernavaca) indican polaridad reversa y por lo tanto sugieren que la actividad volcánica en la región podría haberse iniciado antes de 0.78-0.79 Ma (o bien durante el sub-cron dentro de Brunhes). Los datos disponibles no proporcionan información sobre el caracter continuo o discreto de la actividad. Los datos paleomagnéticos para el complejo volcánico del Ajusco indican polaridad reversa y normal y reversa, respectivamente, lo que sugiere que la actividad volcánica ocurrió en periodos transicionles y excursiones del cmpo geomagÅ„etico probablemente durante el Cron de Brunhes.
Late Cenozoic tectonics offshore western Mexico and its relation to the structure and volcanic activity in the western Trans-Mexican Volcanic Belt
Authors: Delgado Granados Hugo
Published: May 2021

La tasa de convergencia calculada indica que la tectónica del occidente de México ha sido tensional durante los últimos 3 Ma. Este estilo de deformación se ve reflejado en la formación de estructuras rift en la parte occidental de la Faja Volcánica Trans-Mexicana [FVTM]. Los valores obtenidos para la tasa de convergencia predicen que, a través del tiempo, se verifica una tectónica menos tensional (con tendencia a la neutralidad) en la parte sureste de la zona de interacción de las placas de Rivera Y Norteamérica, mientras que en la parte noroccidental se vuelve más tensional. Por otra parte, un análisis cualitativo de las tasas de esparcimiento muestra que éstas fueron más rápidas antes de los 6.5 Ma de lo que fueron posteriormente. Después de analizar diferentes parámetros cinemáticos, se concluyó que la tasa de esparcimiento de la cresta del Pacífico Oriental en su sector Pacífico-Rivera, influye fuertemente sobre la tasa de convergencia. De esta manera se puede establecer una correlación positiva entre la evolución de la tasa de esparcimiento de la cresta Pacífico-Rivera y la geología continental. Esta correlación muestra que tasas de esparcimiento relativamente rápidas coinciden con la presencia de volcanismo monogenético calci-alcalino en la parte occidental de la FVTM cuando menos desde hace 10 Ma y que este tipo de volcanismo continúa hasta nuestros días. Sin embargo, cuando la tasa de esparcimiento se ha hecho más lenta (y por tanto la tasa de convergencia se ha hecho menor) durante el periodo comprendido entre 6.5 Ma y 3.5 Ma, se ha verificado en la región una tectónica extensional ampliamente distribuida, volcanismo explosivo y sedimentación lacustre en los sistemas rift de Colima, Tepic-Zacoalco y de Chapala; particularmente entre los 4.6 Ma y 3.9 Ma ha coincidido con volcanismo alcalino en los rifts fr Colima y Tepic-Zacoalco. Un leve incremento en la tasa de esparcimiento después de los 3.5 Ma coinciden con el decremento de actividad volcánica (principalmente alcalina). Durante el periodo entre 1.6 Ma y 0.7 Ma, la tasa de esparcimiento disminuyó de nuevo coincidiendo con un fallamiento normal continuo en las tres estructuras rift mencionadas y en parte, con otra etapa de volcanismo alcalino (entre 1.4 Ma y 0.2 Ma) en los rift de Colima y Tepic-Zacoalco. Después de los 0.7 Ma, la tasa de esparcimiento se ha incrementado levemente. Por otra parte, se observa una relación genética entre el contenido de elementos compatibles en rocas volcánicas de la región con la tasa de convergencia, lo cual implica que tasas de subducción mayores aportan una mayor cantidad de sedimentos acrecionados a la cuña del manto. Esto explica las diferencias geoquímicas entre las rocas volcánicas a lo largo del frente volcánico de la parte occidental de la FVTM.

Published: May 2021

Se reportan los datos de elementos traza y las composiciones isotópicas de Sr, Nd y Pb en andesitas calco-alcalinas del Volcán Colima y se comparan con otros centros volcánicos del Cinturón Volcánico Mexicano. Los patrones de elementos de Tierras Raras normalizados con respecto a condritas demuestran un enriquecimiento en Tierras Raras ligeras y anomalías despreciables de Eu. Otros diagramas multi-elementos normalizados con respecto a MORB y manto "primitivo" demuestran anomalías negativas de Ta y Ti en las andesitas de Colima. Las relaciones isotópicas varían de 0.70355-0.70358 para 87Sr/86Sr, 0.51295-0.51298 para 143Nd/144Nd, y 18.57-18.59, 15.56-15.58 y 38.27-38.31 para 206Pb/204Pb, 207Pb/204Pb y 208Pb/204Pb respectivamente. Las relaciones isotópicas de Sr y Pb son significativamente menores y 143Nd/144Nd mayor que para la mayoría de las andesitas del Cinturón Volcánico Mexicano.
DESENVOLVIMENTO DE ARGAMASSAS DE REBOCO COM A INCORPORAÇÃO DE CAULIM.
Authors: Silva Beatriz Rocha , Menezes Júnior Hudson Santos , Santos Any Manuela Soares , Da Silva Filho Antônio José , Oliveira Herbet Alves de
Published: May 2021

O caulim é um silicato de alumínio hidratado isento de plasticidade, de cor branca ou levemente bege ou rósea, usado para diversas aplicações, entre elas na fabricação de papel, tinta e outros. Portanto, o caulim é um material nobre de importante valor agregado. Na produção de argamassa normalmente o material é pouco utilizado devido à carência de jazidas no Brasil, ou cuja distância das jazidas existentes inviabiliza os custos de processamento para produção de argamassas. Nesse trabalho a proposta é avaliar o uso do caulim na produção de argamassa de reboco. O caulim foi submetido aos ensaios de caracterização: difratometria de raios X (DRX), análise química por fluorescência de raios X (FRX) e análise de distribuição granulométrica. A partir de um traço de 1:5 em massa (cimento: areia) utilizado para reboco, o mesmo foi utilizado para substituir a areia, de 20 a 80% em massa. Foram produzidos corpos de prova cilíndricos de (10 x 5) cm os quais foram imersos em água potável contendo cal e deixados curando por 28 dias. Após cura, os mesmos foram submetidos aos ensaios de resistência mecânica à compressão, absorção de água e massa específica aparente. Os resultados apresentados indicam que, à medida que o caulim foi incorporado, houve melhora na trabalhabilidade no estado fresco. Após a cura, houve acréscimo da resistência e da massa especifica e redução da absorção de água. A argamassa foi aplicada numa parede-teste e foi observada uma melhora exponencial na textura, mas houve retração diferencial que pode promover fissuração, portanto, deve ser utilizado de forma moderada.
The mediating role of accounting disclosure in the influence of AIS on decision-making: A structural equation model
Authors: Qatawneh Adel , Bader Ayman
Published: May 2021

The current study aims to investigate the influence of accounting information system (AIS) elements, including human resources, physical resources, and financial data, in delivering the organization to a suitable decision-making process through the mediating role of well-built accounting disclosure. The study applies its model to the commercial banks listed in the Jordanian market at the end of 2019. A quantitative approach was adopted and a questionnaire was applied on 171 financial managers and accounting department heads within 21 commercial banks in Jordan. Based on the results of a structural equation model, the main hypothesis was accepted referring to the positive influence of AIS elements of human resource, physical resource, and financial data on organizational decision-making that is attributed to accounting disclosure within commercial banks in Jordan. These results show the importance of AIS in decision-making and encourage companies to adopt modern AIS in order to help them improve the quality of accounting information. The study recommended focusing on increasing skills and knowledge of accounting and financial managers within banks on the multiple ways of benefitting from AIS applications, this can include holding conferences, seminars, and workshops.
Ochronotic heart disease leading to severe aortic valve and coronary artery stenosis
Authors: Velez Ana , Gaughan Natalie , Thomas Rosmi , Schena Stefano
Published: May 2021

Cardiac ochronosis is a rare disease, estimated to affect 1 in 250,000
persons. While there is extensive evidence of the musculoskeletal
alterations of the disease, cardiac involvement has not been widely
studied and most information we currently have derives from case reports
and case series. We report the case of a 64-year old patient with a
known history of alkaptonuria who presented with dyspnea and weight
loss. On evaluation, he was found to have severe aortic stenosis,
coronary artery disease, and interventricular septal hypertrophy.
Surgery revealed extensive ochronotic pigment deposition affecting the
cardiac septum, both internal thoracic arteries, the native coronary
arteries, and the aortic valve. Ochronotic heart disease is an often
disregarded presentation of alkaptonuria. More information is needed on
the course of the disease, as well as long-term outcomes after valve
replacement surgery and/or CABG in patients with alkaptonuria.
Guidelines for reporting protein modelling studies
Authors: Vihinen Mauno
Published: May 2021

Computational modelling tools are widely used, however, articles
describing modelling studies frequently do not contain sufficient
details to allow the reader to comprehend the modelling procedure,
quality of the produced model and validity of interpretations and
predictions made based on the model. Here, guidelines were developed for
items that have to be included when reporting studies and results based
on protein modelling. A brief and concise checklist of required data
items was compiled. These guidelines are simple to follow and apply, but
require meticulous description of details, many of which can be placed
to supplementary material. Authors have to pay attention to details when
reporting modelling process. The generated structural models should be
made publicly available, preferably by submitting to one of the existing
repositories.

Published: May 2021

Background: Patients with tunnelled CVL may develop blood stream
infections which at times are difficult to control without line removal.
Concomitant severe thrombocytopenia with platelet transfusion
refractoriness is often considered a hard contraindication to any
procedure involving a major blood vessel. There is very little
literature on the actual clinical risks of tunnelled central line
removal in febrile pancytopenic patients. Procedure: We analysed
complications and outcomes in all or patients, a total of 52, who
underwent CVL removal with platelets <20,000/uL. Results: No
bleeding episodes or unplanned transfusions could be associated with CVL
removal. No other complications were also reported. All patients had
time to hemostasis within 5 minutes of catheter removal. A total 31
patients were febrile at the time of CVL removal, of which 17 became
afebrile within 2 days. We found no difference in response when
comparing those whose antibiotic therapy was change/escalation versus
those who did not. Removal of CVL under local anaesthesia remained
complication-free even at platelets counts less than 20.000/uL. With
only RDP support 17 lines were pulled out without any complications when
platelets were below 5.000. Conclusion: Our findings suggest that
central lines can be safely removed with platelet counts less than
20.000/ul and that this may result in enhanced blood stream infection
control. This might be particularly relevant to neutropenic patients in
this day and age of MDR germs emergence and paucity of new effective
antibiotics.
Evaluation of IT Companies as Learning Organizations from the Programmers’ Perspective
Authors:   IT company “Autentica”, Katans Edgars , Katane Irena ,   Latvia University of Life Sciences and Technologies
Published: May 2021

The modern social science faces a new synergetic and social-ecological paradigm and the respective approaches in research activity. The synergetic approach allows for the investigation of a learning IT company as a “living” system, a synergic organization notable for its teamwork and team learning to ensure the introduction of innovations in the company and, along with that, a sustainable development and competitiveness of the company in a constantly changing environment. In its turn, the social-ecological approach allows a researcher to focus his attention on a continuous professional development of an individual programmer or a team of programmers by mutual cooperation and interaction with the whole IT company representing the environment of their professional activity and continuous learning. A learning organization has certain traits or indicators, which can be used for the evaluation of IT companies. The authors have developed a methodology for the evaluation of learning IT companies, which has been approved during the experimental research: a case study. 102 programmers working for various Latvian IT companies participated in the study. The aim of the study: to analyse the IT companies where the research participants work, evaluating them as learning organizations, as well as to assess the informational awareness and knowledge of the programmers about the continuous professional development and career growth possibilities at the respective companies. Among the 19 indicators (traits) of evaluation of a learning organization, the following three traits are the most typical ones for the IT companies where the research participants are working: (1) friendly atmosphere and mutual support within a company, cooperation when working as a team, sharing their knowledge, skills, competencies and experience while performing their work duties; (2) a company is trying to ensure its sustainable development and competitive ability; (3) self-education and continuous learning of a company to improve its activity and to diversify the variety of the target groups along with a continuous improvement of its products and services.
The moderating role of personal resources in the relationship between job demands and work engagement
Authors: Chen I-Shuo
Published: May 2021

This study aimed to examine the role of personal resources in the job demands?resources (JD?R) model of work engagement. We hypothesized that personal resources weaken the negative impact of job demands on work engagement. The hypothesis was examined using a sample of employees (N = 58) from multiple branches of four international fast-food chains based in Ireland and Taiwan who completed questionnaires focused on personal resources, job demands and work engagement over 7 consecutive workdays (N = 58*7 = 406 occasions). The results support the hypothesis. Theoretical contributions and practical implications are discussed.
Perceived lack of control and conspiracy theory beliefs in the wake of political strife and natural disaster
Authors: Stojanov Ana , Bering Jesse , Halberstadt Jamin
Published: May 2021

While lack of control is one plausible explanation for conspiracy beliefs, the experimental evidence is mixed. We present two naturalistic studies that offer some limited support for the control hypothesis. In the first, Macedonians living in (North) Macedonia (N = 116) completed a conspiracy ideation scale immediately after a national referendum on the country?s name change from ?Macedonia? to ?North Macedonia,? and one year after. The opposition, whose control was lowered after the name change, increased their conspiracy beliefs, but supporters did not. Study 2, conducted with Americans (N = 266) in the wake of a series of devastating tornadoes, replicated and expanded the first study: the effects were evident only for the threatening event-related conspiracy beliefs. These studies suggest a possible link between lack of control and conspiracy beliefs in the real world.
Local allergic rhinitis - a big challenge in clinical practice
Authors: Stosovic Rajica , Tomic-Spiric Vesna
Published: May 2021

Local allergic rhinitis is a new rhinitis phenotype characterized by symptoms similar to allergic rhinitis, in non-atopic patients with a positive nasal allergen provocation test (NAPT). The disease is diagnosed in over 25% of non-atopic patients with rhinitis, marked as non-atopic rhinitis. It most often has perennial and severe symptoms and a progressive course. It is often associated with conjunctivitis and/or asthma. It is necessary to consider local allergic rhinitis in patients with non-atopic rhinitis. The gold standard for diagnosis is a positive NAPT. Pharmacological therapy fails to stop the natural progression and development of comorbidities. Allergen immunotherapy reduces the symptoms, consumption of medicines and increases the tolerance to allergens responsible for local allergic rhinitis. New studies are needed to confirm the curative effects and evaluate the preventive effects of allergen immunotherapy.

Published: May 2021

Introduction. Over the last few months the coronavirus disease 2019 (COVID-19) pandemic has created overwhelming challenges for physicians around the world. While much has been described in the literature about lung infiltrates and respiratory failure associated with infection of coronavirus 2 (SARSCoV- 2), pneumothorax is reported as a rare (a rate of 1%) but a life-threatening complication of COVID-19 pneumonia. Late bilateral spontaneous pneumothorax has been described in few cases. The aim of the report is to consider pneumothorax as a possible complication of COVID-19 pneumonia, which is also one of the causes of respiratory deterioration and potentially fatal outcome in these patients. Case outline. This article describes the clinical course of the patient who tested positive for SARS-CoV-2 on reverse-transcriptase polymerase chain reaction (RT-PCR) testing of nasopharyngeal and oropharyngeal swab specimens and who presented with COVID-19 pneumonia complicated by bilateral, spontaneous pneumothorax, pneumomediastinum and subcutaneous emphysema. He had no underlying lung disease nor risk factors for pneumothorax, except administered non-invasive ventilation/continuous positive airway pressure during first hospitalization. The patient was successfully treated with surgical (chest drainage, thoracoscopy and pleural abrasion) and non-surgical methods (by application of drugs and other supportive therapies). Conclusion. This review demonstrates that the possibility of a late pneumothorax should be kept in mind in patients with, or recovering from, COVID-19 disease with progressive dyspnea. The timely diagnosis and management of pneumothorax will reduce COVID-19 associated mortality.

Published: May 2021

OBJECTIVE

Depression is common in people with diabetes, but data from developing countries are scarce. We evaluated the prevalence and risk factors for depressive symptoms in patients with diabetes using data from the International Diabetes Management Practices Study (IDMPS).

RESEARCH DESIGN AND METHODS

IDMPS is an ongoing multinational, cross-sectional study investigating quality of care in patients with diabetes in real-world settings. Data from wave 5 (2011), including 21 countries, were analyzed using the 9-item Patient Health Questionnaire (PHQ-9) to evaluate depressive symptoms. Logistic regression analyses were conducted to identify risk factors of depressive symptoms.

RESULTS

Of 9,865 patients eligible for analysis, 2,280 had type 1 and 7,585 had type 2 diabetes (treatment: oral glucose-lowering drugs [OGLD] only, n = 4,729; OGLDs plus insulin, n = 1,892; insulin only, n = 964). Depressive symptoms (PHQ-9 score ≥5) were reported in 30.7% of those with type 1 diabetes. In patients with type 2 diabetes, the respective figures were 29.0% for OGLDs-only, 36.6% for OGLDs-plus-insulin, and 46.7% for insulin-only subgroups. Moderate depressive symptoms (PHQ-9 score 10–19) were observed in 8–16% of patients with type 1 or type 2 diabetes. Female sex, complications, and low socioeconomic status were independently associated with depressive symptoms. In type 1 diabetes and in the type 2 diabetes OGLDs-only group, depression was associated with poor glycemic control.

CONCLUSIONS

Depressive symptoms are common in patients with diabetes from developing countries, calling for routine screening, especially in high-risk groups, to reduce the double burden of diabetes and depression and their negative interaction.
Associations of Diet Quality and All-Cause Mortality Across Levels of Cardiometabolic Health and Disease: A 7.6-Year Prospective Analysis From the Dutch Lifelines Cohort
Authors: Vinke Petra C. , Navis Gerjan , Kromhout Daan , Corpeleijn Eva
Published: May 2021

OBJECTIVE

To simultaneously investigate the association of diet quality and all-cause mortality in groups with varying cardiometabolic diseases (CMDs) at baseline.

RESEARCH DESIGN AND METHODS

From the population-based Lifelines cohort, 40,892 non-underweight participants aged ≥50 years with data on diet quality and confounding factors were included (enrollment 2006–2013). From food-frequency questionnaire data, tertiles of the Lifelines Diet Score were calculated (T1 = poorest, T3 = best diet quality). Four CMD categories were defined: 1) CMD free, 2) type 2 diabetes, 3) one cardiovascular disease (CVD), 4) two or more CMDs. Months when deaths occurred were obtained from municipal registries up until November 2019. Multivariable Cox proportional hazards models were applied for the total population and stratified by CMD categories.

RESULTS

After a median follow-up of 7.6 years, 1,438 participants died. Diet quality and CMD categories were independently associated with all-cause mortality in crude and adjusted models (P < 0.001). A dose-response relationship of diet quality with all-cause mortality was observed in the total population (Ptrend < 0.001, T2 vs. T3 = 1.22 [1.07–1.41], T1 vs. T3 = 1.57 [1.37–1.80]). In stratified analyses, the association was significant for CMD-free individuals (T1 vs. T3 = 1.63 [1.38–1.93]) and for patients with type 2 diabetes (1.87 [1.17–3.00]) but not for patients with one CVD (1.39 [0.93–2.08]) or multiple CMDs (1.19 [0.80–1.76]).

CONCLUSIONS

A high-quality diet can potentially lower all-cause mortality risk in the majority of the aging population. Its effect may be greatest for CMD-free individuals and patients with type 2 diabetes. Tailored dietary guidelines may be required for patients with extensive histories of CMDs.

Authors: AŞÇI Taner , KÜÇÜKTÜVEK Mustafa , KESKİN Hakan
Published: May 2021

One of the important factors that should be considered in architecture is the fire resistance of the materials used. This study, it is aimed to increase the fire resistance of particleboards, which are widely used in architecture. For this purpose, it is aimed to improve the fire resistance by using a new type of impregnation material obtained by modifying boron compounds with rosin additive. Within this context, particleboard samples prepared in accordance with TS 642 ISO 554 were sized according to ASTM-E 160-50. Combustion tests of prepared samples were done in accordance with ASTM-E 160-50 E, and the values obtained through the tests on the basis of burning time, weight loss ratios, FsC, SC, Gp temperatures were compared with the control samples. As a result, it was observed that average temperature values of FsC, SC decreased by 5%, Gp decreased by 1,8%, weight loss was reduced by 0,5% and the combustion period was increased by 2%. This case can be taken into account in the field where particleboard is used with high fire risk in architecture.
School Composition, Disruptive Classroom Behaviour and Student Results: A Study of Mechanisms of Peer Effects
Authors: Bäckström Pontus
Published: May 2021

This study analyses whether disruptive classroom behaviour affects students’ results in Swedish lower secondary schools (N = 1704), measured by the schools’ grade point averages (GPA). The data, collected from the Swedish school authorities, comprises variables on schools’ pupil composition, classroom environment and student mean grades. Previous research has shown that disruptive classroom behaviour has a negative impact on students’ results. This study finds such effects. The effect size reported is equal to the reported GPA differences between boys and girls. Results show that some of the original effects of school compositional variables are mediated through disruptive behaviour.
Prevalencia de enfermedad periodontal relacionada con parto pretérmino y bajo peso al nacer. Hospital Mariana de Jesús
Authors: Bazurto María José , Luzardo Jurado Geoconda
Published: May 2021

Introducción: la enfermedad periodontal es una infección multifactorial cuyo agente etiológico es la placa bacteriana, provocando indudablemente la liberación de células proinflamatorias que afectan otros sistemas. La asociación de la enfermedad periodontal con el bajo peso al nacer y el parto pretérmino se basa en que los mediadores de la inflamación podrían difundirse a la unidad fetoplacentaria, a través de la circulación sanguínea. Metodología: estudio observacional, transversal y descriptivo, donde se examinaron 82 mujeres puérperas entre los 14 a 45 años que dieron a luz entre junio y agosto de 2017 en el hospital Mariana de Jesús, que cumplían con criterios de inclusión: mujeres puérperas que hayan tenido un parto prematuro y mujeres que den a luz a niños con bajo peso. Resultados: en relación a la prevalencia de la enfermedad periodontal se encontró que el 70,73% presentaron gingivitis, de las cuales tuvieron parto prematuro en un 68,29% y parto muy prematuro 31,71% y neonatos con bajo peso al nacer en un 40,24%, neonatos con muy bajo peso 12,20% y neonatos con extremadamente bajo peso 13,41%; demostrando así la íntima relación entre la enfermedad periodontal con el parto pretérmino y el bajo peso al nacer. Conclusión: en este estudio se demuestra que las mujeres con EP, específicamente gingivitis presentan un mayor porcentaje de partos prematuros/muy prematuros y neonatos con bajo peso, muy bajo peso y extremadamente bajo peso; lo cual tuvo prevalencia en mujeres jóvenes de entre 14-29 años que son las que tienen más riesgos; concluyendo que la enfermedad periodontal constituye un factor de riesgo para los PP y neonatos con BPN.

Active children through individual vouchers – evaluation (ACTIVE): A mixed method randomised control trial to improve the cardiovascular fitness and health of teenagers
Authors:   , James Michaela L.
Published: May 2021

To experience the health benefits of physical activity, it is recommended thatchildren and young people take part in at least 60 minutes of moderate to vigorousactivity on average per day across the week. In Wales, only 11% of girls and 20% ofboys are reported to meet these government recommendations with accessibility(e.g., cost and lack of local facilities) cited as the main barrier to participation. Todate, interventions have experienced short-term success. These interventions oftenplace emphasis on policymakers as the leaders, or experts on the matter in question.However, this can result in a disconnect between what is provided and what thegroup receiving the intervention value and need. The Active Children throughIndividual Vouchers – Evaluation Project (ACTIVE), funded by the British HeartFoundation (BHF), aimed to empower teenagers and tackle accessibility barriers toimprove the physical activity, cardiovascular fitness, motivation and heart health ofthose aged 13 – 14 in south Wales. This study was co-produced by teenagers from itsinception to delivery of the ACTIVE intervention and included a multi-componentintervention encompassing a voucher scheme, peer mentoring and support workerengagement. The ACTIVE RCT had a positive impact on cardiovascular fitness andblood pressure as well as perceptions of activity. The findings from observationaldata provide some key predictors of teenage health which can be used to be proactivein promoting healthy behaviours in young people and identifies some protectivefactors which can be promoted to families and first-time parents. The key messagefrom ACTIVE is that young people want to have their say in activity provision sothat they can increase their opportunities to participate in unstructured, fun and socialactivity in their local communities. To improve physical activity, more should bedone to listen to teenagers as to what they want and need.

Thermo Power Plant “Kosovo B”– A Pollution Source for Sitnica River
Authors: Kajtazi Besime Sh. , Floqi Tania
Published: May 2021

Kosovo’s waters are unevenly distributed in time and space. Kosovo is water scarce, and it also has the low level of water resources development and storage. In particular Iber basin is water stressed, but in the next 20 years it is expected that all Kosovo’s basins will be water stressed [1]. This is due to population and general economic growth, and resource variability. The anticipated revitalization of the irrigation and mining sector and additional demands from the energy sector will increase pressure on new water demands [5]. For these reasons, the water quality of existing resources will become an ever-growing problem if not addressed now. The lignite-fired power plant “Kosovo B” is main the energy source in the country. The wastewater produced from its operation is discharged into Sitnica river with minimum treatment. With study of pollution level of wastewater discharges, this article sets several recommendations for treatment of wastewater in order that power plant meets national and EU operation requirements.
Addictive Behavioural Manifestations of Adolescents in Romania
Authors: Colareza Corina , Neacșu Ioan
Published: May 2021

The study examines, through a concrete research, the analysis of perceptual, ideational, attitudinal, social, family and personological factors, with cumulative-progressive effects in the genesis of the main primarily addictive behavioural forms, in groups of adolescent pupils. The approach of the topic is an interdisciplinary one, the dominant being the psychological, sociological and pedagogical dimensions, in a context seen as a reality lived and expressed verbally by the teenagers constituted investigatively in a randomly structured sample from different urban localities, either as opinions or as behavioural social and emotional-affective states specific to adolescence. The qualitative arguments and the statistical results are the materialization of the application of a valid research methodology, relevant in its associative and explanatory interactional complementarity. The conclusions of the study are relevant due to their functionality, which can possibly materialize in minimal positive interventions prior to the actual addiction in adolescent pupils in today’s Romania.

Authors: Truța Luciana , Chiș Olga
Published: May 2021

The present study aims at identifying some efficient ways regarding the development of the pedagogical practice of students in the Pedagogy of Primary and Preschool Education in a synchronous format. Thus, a series of aspects were identified during the first semester that helped us to highlight the strategies that allow students a good knowledge and understanding of the aspects related to pedagogical practice. The study focused on several components viewed and analyzed from two perspectives: of students with studies in the pedagogical field and of those with studies in another field. Thus, the components followed were: ways of conducting meetings in a synchronous format, methods used, the degree of applicability of the contents, the capacity for reflection and self-reflection on the competencies of the teacher, difficulties and suggestions for improvement. The study’s conclusions were based both on the students’ answers to the applied questionnaire, but also on the analysis performed by the pedagogical practice tutors, resulting in the fact that the strategies used had an impact on all students and that in the future encouraged autonomy in learning.
Arte y naturaleza en Física II
Authors: Ross Alberto
Published: May 2021

El propósito de este trabajo es ofrecer una reconstrucción de los usos que se pueden encontrar de la analogía entre phúsis y tékhne en el libro II de la Física de Aristóteles. Intentaré mostrar que el filósofo griego recurre a ella con fines tanto ilustrativos como argumentativos, lo cual revela una visión muy original acerca del orden de la realidad. En aras de atender a lo propuesto, explicaré primero el uso de la analogía que aparece en el contexto de la definición de la naturaleza. En segundo lugar, revisaré los pasajes en los que nuestro autor aclara los sentidos en los que cabe hablar de la noción de phúsis y, finalmente, presentaré el uso de la comparación mencionada en la argumentación de Física II 8, en donde Aristóteles defiende la existencia de causas finales en la naturaleza.
La interpretación de la naturaleza
Authors: Vallejo Campos Álvaro Pablo
Published: May 2021

La metafísica puede entenderse como una disciplina cuyo objeto son entidades inteligibles, pero es también y, sobre todo, comienza siendo una interpretación de la naturaleza. La inversión nietzscheana del platonismo tiene en la crítica del finalismo uno de sus rasgos principales. La oposición aparente/verdadero, desde esta perspectiva, se explica en función de la ausencia o la presencia de finalidad en la interpretación de la naturaleza, pero a juicio de Nietzsche la finalidad forma parte de la apariencia y no de la realidad del mundo natural. Independientemente de la valoración y de la genealogía que atribuye al pensamiento platónico, a mientender, su interpretación del platonismo es en lo esencial certera, pues Platón intentó ofrecer con la teoría de las ideas una concepción de las causas del devenir, basada en las categorías de finalidad y unidad, que calificó como «segunda navegación» precisamente porque constituía una alternativa a la teoría de la naturaleza transmitida por los presocráticos.

Cryptosporidium spp. and helminths are responsible for diarrhoal illness in humans and many other animals. The transmission routes of these parasites suggest a risk for human infection through contaminated foods. In order to determine the occurrence of Cryptosporidium oocysts and helminth ova on dried crayfish (Procambarus clarkii) sold in Zaria and Kaduna Central market, Kaduna State, 100 crayfish samples were examined using the modified Ziehl-Neelsen staining technique for Cryptosporidium oocyst and the flotation technique for helminth ova. The measurements of the oocysts from the positive samples were estimated by using a calibrated microscope eyepiece. The prevalence of Cryptosporidium oocysts in dried crayfish was 20.0 % while the location-based prevalence was 43.3 %, 5.0 %, and 12.0 % for Sabo, Samaru and Kaduna central market, respectively. Micrometry revealed that the oocysts size ranged from 3.68 µm to 4.7 µm. Also, the prevalence of helminth ova in dried crayfish was 19 %, while the specific prevalence based on location showed a higher prevalence in Sabo (30.0 %) than in Kaduna central market (18.0 %) and Samaru (5.0 %). The helminth eggs recovered from this study included: Toxocara spp. (4.0 %), Ascaris spp. (7.0 %), Trichuris spp. (4.0 %), Schistosoma spp. (2.0 %), Ancylostoma spp. (1.0 %), and Capillaria spp. (1.0 %). The analysis of the questionnaires revealed that 71 (71.0 %) of the respondents ate uncooked cray-fish and 44.0 % used their bare hands to handle the cray-fish. There was no statistically significant association (P > 0.05) between the prevalence of Cryptosporidium oocysts or helminth ova and the locations sampled. This study has shown that dried crayfish obtained from markets within the study area were contaminated with parasite ova and oocysts, thus public enlightenment on the dangers of the consumption of raw or undercooked dried crayfish should be well publicized.
