Authors: Escobar José Carlos 
Published: February 2022

Son muchos los años, 22 para ser exactos, en los que Decires, la revista académica del CEPE, ha estado vigente gracias al entusiasmo de quienes la han visto como el espacio ideal y propio para publicar sus ideas, estudios, investigaciones y descubrimientos. Además, ha sido una revista que ha ayudado a cohesionar la teoría con la práctica en lo que se ha denominado “enseñanza del español a extranjeros”. En el área de español, ha sido un baluarte en la formación continua de sus profesores y profesoras, y se ha constituido en una fuente de referencia y en un instrumento de socialización del conocimiento entre el claustro de profesores sobre los temas más diversos. Surgida en respuesta a la labor universitaria de la difusión del conocimiento, tuvo como antecedentes las revistas Mascarones (de 1982 a 1988) y El Boletín (de 1989 a 1992), lo cual significa que es ahora una tradición académica, con un acervo de artículos que muestra las capacidades e intereses del CEPE.
En esta contribución se presenta una relatoría comentada de lo publicado en Decires, que se inició en 1998 y transitó a lo digital en 2005 para facilitar el acceso a esta revista académica en beneficio de un público amplio, además de contribuir así al ahorro de papel y de espacio. Se reseñan las contribuciones hechas en 22 años y se deja constancia de lo publicado, lo cual sin duda es de interés no solo para los profesores del CEPE, sino para el público interesado.

Relationship between empirical laws of turbulent combustion of dust/air mixtures
Authors: Poletaev N. L. 
Published: February 2022

Introduction. An array of known experimental data, mainly obtained in a standard 1 m3 chamber, is considered in the article. It allowed to identify the nature of three dependences of the turbulent combustion of dust, including the dependences of limited oxygen concentration (LOC) and explosive index Kst on the energy of ignition source Eig (on a logarithmic scale) and the dependence of Kst on the initial oxygen content in the air Cox.Empirical dependencies. The analysis showed that all considered dependences, having a relative accuracy of about 20 % can be represented as linear functions of an argument varying within the following limits: Eig varies from minimum ignition energy Emin to 10 kJ; Cox ranges from LOC to 21 % vol. According to the nature of dependence of Kst on Eig, all dusts are divided into two types. For the first type of dust, Kst does not depend on Eig. For the dust of the second type, Kst ∝ (Eig – Emin).Relationship of empirical dependencies. It is shown that the considered empirical dependences should be interrelated for the dust of the second kind. Namely, slopes Cn (n = 1, 2 or 3 as the number of the dependence) of linear functions, approximating the empirical dependences for a particular dust sample, satisfy the relationship: С2(21 vol. %) = –С1∙С3(10 kJ). Due to the absence of a dust sample, for which data on all three dependences are available, the obtained relationship was confirmed for the average values of parameters: <С2(21 vol. %)> = =–<С1>∙<С3(10 kJ)>.Discussion of the result. The satisfactory accuracy of the relationship between C1, C2 и C3 gives rise to the confidence in the objectivity and relationship of the considered empirical dependences of the turbulent combustion of dust.Conclusions. It is shown that the considered empirical dependences of the turbulent combustion of dust in a 1 m3 chamber are interrelated and the form of this relationship is identified.
Contribuições da Psicologia para a relação professor-aluno
Authors: Pena Alexandra Coelho 
Published: February 2022

As concepções de diferentes abordagens da psicologia – e de outros campos de saber – sobre como o ser humano conhece podem contribuir para a compreensão da relação que se estabelece entre adultos e crianças, adultos e adolescentes e adultos e adultos nos diversos segmentos educacionais, da creche à universidade. Trata-se de artigo de revisão de literatura que tem por objetivo explicitar os principais conceitos das teorias de Jean Piaget, Lev Vigotski, Wilhelm Reich e Martin Buber, buscando com isso elementos que ajudem na compreensão da complexa relação professor-aluno, que vai além da sala de aula, rompendo com uma concepção de ensino como transferência de conhecimento. Essa relação se constrói em um determinado tempo e espaço, marcados por valores, ideologias, normas e discursos. As contribuições da psicologia para a educação devem caminhar no sentido de ajudar a compreender as complexas interações que se estabelecem no interior das instituições educativas, contextualizando os fenômenos e abordando-os no âmbito das relações entre as pessoas, considerando a complexidade que envolve essa discussão.

O presente artigo tem o objetivo de evidenciar a importância da percepção por parte dos sujeitos, em uma escola do Campo, sobre as contradições entre as políticas públicas e elementos identitários durante a vivência do processo de uma Investigação Temática Freireana (IT), que envolveu o universo temático da Biodiversidade. A investigação foi estruturada a partir de metodologia do tipo etnografia escolar com a técnica de observação participante, com utilização de gravação de áudio e imagens para o processo de elaboração, com a coparticipação dos estudantes do Ensino Médio regular noturno de uma escola do Campo do Município de Uberaba-MG, de uma intervenção pedagógica. Assim, foram identificadas cinco possíveis contradições figuradas como propostas de temas geradores: maus tratos na linha de produção, uso de agrotóxico, contaminação do solo pelo descarte inadequado de resíduos sólidos, solo infértil e desigualdade social na distribuição de terra, utilizados para desenvolvimento da Intervenção Didática (ID). Os resultados indicam a potencialidade de processos investigativos e problematizadores para a percepção de contradições e situações limite no contexto da escola do campo em estudo, além disso, como tais aspectos percebidos interferem no engajamento dos sujeitos, no processo de apropriação das noções envolvendo a biodiversidade local.
CFO Gaps: Determinants and Impact on the Corporate Information Environment
Authors: Chen Xia , Li Na , Lin An-Ping 
Published: February 2022

ABSTRACT
A CFO gap arises when the CFO position is left vacant for a period between the departure of the old CFO and the appointment of a new CFO. We find that CFO gaps are fairly common; over the sample period 2004–2016, approximately one-third of CFO turnovers are associated with a CFO gap, lasting, on average, two quarters and two months. CFO gaps are more likely for firms that face more labor market search frictions and with financial reporting and performance issues, and are less likely for firms with succession plans and with greater growth opportunities. While CFO gaps are not associated with significant changes in firms' financial reporting quality, they are associated with significantly negative changes in firms' voluntary disclosure frequency and analysts' forecast quality. Our findings shed light on the factors that influence top executive gaps and the impact of such gaps on firms' information environment.
TUĞRUL BEY’İN TÜRKMEN SİYASETİ (ERKEN SELÇUKLU ÇAĞINDA İKTİDAR-GELENEK ÇATIŞMASI VE SOSYO-POLİTİK YANSIMALARI)

Published: February 2022

Büyük Selçuklu Devleti’nin kuruluşunda Türkmenlerin potansiyel gücünün etkisi malumdur. Türkmenlerin savaşçı ve mücadeleci ruhu, Horasan’daki bağımsızlık mücadelesi döneminde düzenli ve mücehhez Gazneli ordusuna karşı gerçekleşen savaşlarda Selçuklulara önemli avantajlar sağlamış, neticede bu kitlesel gücü iyi kullanan Selçuklu hanedan üyeleri, Horasan’da bir devri kapatıp yeni bir devri açmayı başarmışlardır. Horasan’da göçebe karakterli bir devletin kurulduğunu duyan uzak sahalardaki Türkmenler de bu yeni devlete tabi olmak için bu bölgeye akın etmişlerdir. Ancak göçebe kökleriyle kurulmuş olsa da Selçuklu Devleti’nin kısa süre zarfında batıya yönelerek farklı ulus ve devletlerle irtibata geçmesi, özellikle İran coğrafyasına egemen olup İran/Sasanî devlet zihniyetiyle bütünleşmesi, yeni kurulan devletin göçebe hususiyetlerinden tedrici şekilde uzaklaşması anlamına geliyordu. Bürokrasi ve yönetimde İran kökenli devlet adamlarının işbaşına getirilmesiyle daha da belirginleşen bu durum,
Tuğrul Bey döneminde Türkmenlerin duygusal kırılmalar yaşamalarına ve bazı tehlikeli isyanlara iştirak etmelerine neden olmuştur. Bunun dışında en başından itibaren aile içi rekabet sebebiyle Tuğrul ve devletinden uzak durmaya çalışan “Irakiyye Türkmenlerinin” hareketlilikleri, İran sınırlarını aşıp Anadolu’ya gelmeleri, özellikle el-Cezire ve Irak’ta önemli bir huzursuzluk âmili olmaları gibi gelişmeler, Tuğrul Bey döneminde Türkmen ve göçerler meselesinin sürekli gündemde kalmasına neden olmuştur. Bu tarihten itibaren Tuğrul Bey’in Türkmenlere karşı gözle görünür şekilde değişmeye başlayan politikası taraflar arasında zaman zaman huzursuzluklara, isyanlara, hatta çatışmalara sebep olmuştur. Bu makalede, Tuğrul Bey döneminde Türkmenler üzerinde takip edilen politika ve Türkmenlerin buna karşı gösterdikleri duygusal ve fiili tepkiler ele alınmaya çalışılacaktır.
Antioxidants for Health Management
Authors: Salim Fatimah , Adnan Noorazlina , Shuib Nor Syarmila , Mohd Yusof Raihana 
Published: February 2022

Antioxidants are technically reductant molecules that prevent the oxidation of other molecules. As other living systems, human biological molecules are also prone to oxidation reactions. In order to repair all of the oxidation damage, human body is naturally producing antioxidants or known as endogenous antioxidant. Unfortunately, the body’s production of antioxidants declines with age and this is found to be a strong factor in contributing to premature aging and degenerative diseases. Researchers have found that exogenous antioxidants which are obtained from foods may work together with endogenous antioxidants to maintain the redox reaction balance in the body. There are thought to be hundreds and possibly thousands of substances that can act as exogenous antioxidants including carotenoids, flavonoids, indoles, polyphenols, essential vitamins (A, C, E), and the minerals copper, zinc, manganese, and selenium. Thus, this paper intended to give insights on the endogenous and exogenous antioxidants, supplements as antioxidant, as well as guiding readers to get benefits of antioxidants from foods for a better health management. It was found that diet containing fruits and vegetables link to superior overall health effects. However, fruits and vegetables should be consumed regularly by considering the right cooking method to get the best effect due to the fact that some antioxidants are sensitive to some cooking method. Apart from diet containing high antioxidants, adopting active lifestyles with consistent exercise and stress management are also required to ensure good and long lasting health.

Published: February 2022

Abstract

OBJECTIVE
To compare the application and healing of the zip skin closure system (ZSCS) with sutured closure by use of a split-scar model of ventral midline incisions in horses in a prospective, randomized experimental study.

ANIMALS
8 adult horses.

PROCEDURES
All horses underwent an exploratory ventral midline celiotomy with a standardized 30-cm skin incision. Each horse was randomized to have either the cranial 15 cm closed with suture and caudal 15 cm with the ZSCS or vice versa (split-scar model). Skin closure time was recorded and compared. Photography and skin biopsies were taken preoperatively and 14 days postoperatively. Cosmetic appearance was assessed by use of a proposed equine celiotomy incision score. Healing at 14 days was assessed by histopathology.

RESULTS
Skin closure times were faster with the ZSCS compared to sutured incisions. At 14 days postoperatively, the cosmetic appearance (equine celiotomy incision scores) for ZSCS incisions were better than sutured closure and histologic healing scores were not different between methods of closure. Subcuticular sutures were associated with deep dermal inflammation and necrosis independent of epidermal closure methods.

CLINICAL RELEVANCE
While limitations to the utility of the ZSCS are recognized, the potential benefits of expedient closure, good cosmetic outcome, and satisfactory healing make this method viable for closure of linear wounds or incisions in horses.

Published: February 2022

Summary

Introduction
Flavonoids are widely distributed in the wild. They constitute a large group of compounds that have a beneficial effect on the human body. Apigenin and kaempferol, which belong to the flavone subgroup, have, inter alia, an antitumor effect. The influence of these compounds on the survival of stem cells in a toxic environment has not yet been studied.

Objective
The aim of the study was to evaluate the effect of selected concentrations of apigenin and kaempferol on the survival of mesenchymal stem cells (MSC) in the presence of a cell-death inducer – staurosporine.

Methods
Mesenchymal stem cells that were obtained from the Wharton’s jelly of umbilical cords were used for the research. In the first stage, the MSC were treated with apigenin at concentrations of 1.2, 12.5, 25, 50 and 100 µM/ml and kaempferol at concentrations of 1.2, 12.5, 25, 50 and 100 µM/ml. In the next stage, the effect of increased concentrations of 0.1, 0.5 and 1 µM/ml of staurosporine on MSC was examined. The key stage of the experiment was investigating the interaction between the selected concentrations of apigenin (12.5 and 50 µM/ml) and kaempferol (12.5 and µM/ml) on MSC in the presence of staurosporine at a concentration of 1 µM/ml, which had the highest toxicity.

Results
Both apigenin and kaempferol significantly increased the cytotoxic features of staurosporine on the MSC culture.

Published: February 2022

Description du sujet. Les ligneux fourragers constituent une source importante pour la survie des ruminants en période de soudure. Vu la pression qu’ils subissent et par conséquent leur rareté dans les terres de parcours, une étude a été conduite dans la zone de transition soudano-guinéenne du Bénin auprès des populations riveraines des forêts classées des Monts Kouffé, de Wari-Maro et de l’Ouémé supérieur. Objectifs. L’étude vise à identifier les ligneux fourragers prioritaires pour le pastoralisme, analyser l’utilisation et les intensités de coupe des ligneux fourragers en relation avec les différents groupes sociolinguistiques de la zone d’étude et évaluer leur priorité pour la conservation. Méthode. Les données de la littérature ont permis de compléter celles issues des enquêtes afin de constituer une base de données sur différents critères définis. Les taux de citation des espèces par les populations ont permis d’établir leur priorité pour le pastoralisme, alors que la priorisation des ligneux pour la conservation est réalisée avec une combinaison de quatre méthodes et neuf critères. Résultats. Les résultats montrent que 48 espèces sont utilisées comme fourrage aérien et réparties en 17 familles dominées par les Leguminosae (27,1 %) et les Moraceae (16,6 %), et 37 genres dont le plus représenté est le genre Ficus (16,6 %). L’appétibilité, la disponibilité des espèces et leur productivité (au niveau des animaux) sont les critères de choix des ligneux fourragers par les différents groupes sociolinguistiques. Afzelia africana, Pterocarpus erinaceus, Khaya senegalensis, Vitellaria paradoxa, Mangifera indica, Ficus platyphylla, Balanites aegyptiaca, Annona senegalensis, Ficus umbellata et Daniellia oliveri sont les dix premiers ligneux fourragers prioritaires identifiés pour la conservation dont la plupart se trouvent prioritaires pour le pastoralisme. Conclusions. Pour une exploitation rationnelle des ligneux fourragers, nous suggérons l’utilisation des espèces prioritaires aussi bien pour le pastoralisme que pour la conservation dans les plans d’aménagement des parcours naturels au cours des activités d’afforestation/reforestation et de reboisement.
