Published: June 2019

Las incrustaciones minerales representan uno de los problemas más frecuentes en la industria petrolera, ya que deterioran los sistemas de producción, ocasionando pérdidas de presión y, consecuentemente, la disminución de la producción de hidrocarburos. Con base en esta problemática, se realizó esta investigación cuyo propósito fue evaluar la eficiencia de un inhibidor de incrustaciones natural a base del mucílago de la hoja de la planta de cayena (Hibiscus rosa sinensis) en muestras de agua sintética y de producción. Para ello, se realizó la caracterización físico-química de las muestras de agua, así como del mucílago previamente extraído de la planta. Posteriormente, se formuló y caracterizó el inhibidor a tres concentraciones diferentes (2, 4 y 6 % m/V) y se evaluó la eficiencia del producto en ambas muestras de agua, considerando tres (3) dosis diferentes (55, 100 y 500 ppm) y siguiendo los lineamientos planteados en la norma NACE TM0347-2007, resultando más eficiente el inhibidor de 2 % m/V en su dosis más alta. Adicionalmente, se utilizó un inhibidor comercial de la empresa Halliburton para fines comparativos en un análisis estadístico que indicó la ausencia de una diferencia estadísticamente significativa entre el producto a 2 % m/V y el inhibidor comercial.

The cavernous esophagus hemangiomais a rare, benign vascular neoplasm of the esophagus, which is asymptomatic and can be detected by chance during diagnostic video gastroscopy.The aim ofthe study is to describe in the rare clinical case of diagnosis and an integrated approach in choosing an endoscopic method of treating a submucosal benign vascular neoplasm of the esophagus (cavernous hemangioma).Material and method. A 46-year-old patient was sent to the University Hospital of ZSMU to conduct video esophagogastroduodenoscopy in order to examine and select the treatment method for the submucosaltumor of the upper third of the esophagus found in one of the city’s clinics.Results. A comprehensive examination of the patient with a submucosal neoplasm of the upper third of the esophagus, including video esophagogastroscopy with high-resolution endoscopes (EGD), endoscopic ultrasonography (EUS), and computer-aided tomography (CT) were performed. At the EGD a submucosal tumor was reviled in the upper third of the esophagus. It was bluish in color, had a wide base, 3cm in length and 2cm in height, movable, with soft-elastic consistency. EUS revealed that the tumor is not associated with the muscular layer, has many small vessels. The structure of the neoplasm was hypoechoic, inhomogeneous due to the inclusion of calcinates. On CT scan a rounded tumor was found in the lumen of the upper third of the esophagus, 20x15x30mm in size, with clear and even margins, homogeneous structure with a single calcinate in the structure was found. The patient was underwent of endoscopic surgery. The tumor was removed by the endoscopic submucosal dissection (ESD).Conclusion. Cavernous esophagus hemangioma is a rare vascular submucosal neoplasm of the esophagus, which is usually asymptomatic, but has a great potential for complications such as bleeding, which is sometimes fatal. Timely diagnosis and minimally invasive endoscopic treatment methods are the prevention of complications and the treatment of choice for the treatment of esophageal submucoustumors.

Published: June 2019

Four well-known
isotherm models were appropriated to investigate the adsorption process
mechanism in the radioactive
99mTcO4- adsorption
from aqueous solution by using activated carbon as adsorbent. According to R2 values, the experimental data is found to be suitable
for the four isotherm models. However, when the adsorption capacities of the
experimental and calculated from models are compared, it has been seen that the
isotherm models best suited to the experimental data are Langmuir and Temkin. The maximal monolayer
adsorption capacity value founded from Langmuir isotherm model is 3170 µCi.g-1. The dimensionless separation
factor (RL) value indicating a favorable adsorption experiment is
0.126. Also from Freundlich Isotherm model, the adsorption intensity (n) value
which indicates favorable adsorption is 1.72. The heat of adsorption process
was estimated from Temkin Isotherm model to be 724 J/mol and the mean free
energy was estimated from D-R isotherm model to be 13.4 J/mol. According to these data, it can be said that the
adsorption process is realized by physical adsorption. The results showed that
the activated carbon was to be a successful adsorbent for the removal of radioactive
99mTcO4- from aqueous solutions.

Müdelles hadis, zayıf hadis içerisinde değerlendirilen rivayet çeşitlerinden biri
olarak kabul edilmektedir. İlk dönem hadis âlimleri tarafından herhangi bir
değerlendirmeye tabi tutulmayan tedlîs, daha sonraki zaman dilimlerinde zem
edilmiş ve kizb ile eş değer kabul edilmiştir. Rivayetlerin terkine dönük
kusurlardan sayılan “tedlîs” yoluyla rivayette bulunmaya,
münekkitlerce sika addedilen râviler de başvurmuşlardır. Söz konusu bu yöntemle hadis nakleden râvilerin rivayetleri,
bazı şartlar
dâhilinde kabul edilmişken bu şartları haiz olmayan rivayetler ise cerh
edilerek terkedilmiştir. Araştırma konumuz olan Basra’da birçok râvi tedlîs
yoluyla rivayette bulunmuştur. Özellikle bu râvilerin ekseriyeti hadis
münekkitlerince hadis rivayetinde sika olarak nitelendirilmiştir. Söz konusu râvilerin
tedlîs yoluyla naklettikleri rivayetleri hadis âlimlerince değerlendirmeye tabi
tutulmuştur. Yaptığımız tetkikler sonucunda Basra’da tedlîs yoluyla rivayette
bulunan ve bundan ötürü müdelles olarak cerh edilen râvilerin hadis
rivayetlerindeki durumları irdelenmiştir. Elde edilen bilgiler ile bu râviler
hakkında değerlendirmelerde bulunulmuştur. Ayrıca râvilerimizin yaşadığı belde olan
Basra tarihi hakkında da bilgi verilip ilk üç asırda Basra’da hadis ilminin

makalede, modern dönemin önde gelen entelektüel sosyologlarından biri olan Zygmunt
Bauman (1925-2017)’ın düşüncesi din sosyolojisi bağlamında değerlendirilmektedir.
Bu çerçevede ilk olarak Bauman’ın entelektüel soykütüğü kısaca tanımlandıktan
sonra din sosyolojisi ile ilgili yaklaşımı ele alınmaktadır. Buna göre Bauman’ın
toplum muhayyilesinden hareketle din sosyolojisi, akışkan din sosyolojisi
olarak tanımlanmaktadır İkinci olarak Bauman’ın sosyolojisinde bu kontekste
uygun olarak öne çıkan Tanrı, din, monoteizm, politeizm ve belirsizlik gibi
konular ele alınarak tartışılmaktadır. Bu çalışmada temel referans kaynağımız
ise Bauman’ın Stanislaw Obirek ile yapmış olduğu söyleşilerden oluşan “Tanrı’ya
ve İnsan’a Dair (2018)” adlı çalışmadır. Sonuç olarak ise bu makalede akışkan
din sosyolojisine dair öne çıkan yaklaşımın daha çok genel felsefesi üzerine

El modelo que obtuvo un mejor ajuste fue el modelo de 10 ítems con dos dimensiones, a saber: conducta prosocial por un lado, y empatía y apoyo emocional por otro. La escala completa obtuvo un coeficiente alfa de .78. Ambas dimensiones correlacionaron positivamente con las tendencias prosociales sensible, anónima y pública.</p>
Propiedades métricas de la Escala Salvadoreña de Autoritarismo de Derechas (RWA)
Authors: Orellana Carlos Iván 
Published: June 2019

The aim of this work is to expose the metrical properties of the Salvadorian Right Wing Authoritarianism Scale (RWA), developed by Orellana (2017). Based on a sample of 421 inhabitants, 15 years of age and older (M = 39.2; DE = 17.2) from the San Salvador Metropolitan Area (SSMA), the scale is the product of a process of selection of questions already adapted or included in public opinion surveys or political culture polls. According to the Cronbach ´s Alpha coefficient, the scale presents a satisfactory total internal consistence (? = .83). A confirmatory factorial analysis evidences an adequately fitting model, that reproduces the recognized three-dimensional factorial structure of Altemeyer´s RWA (1996; construct validity). The scale correlates with certain constructs (e.g., dimensions of political culture, citizen insecurity and psychosocial dispositions as prejudice) in theoretical and empirical concordance with the former studies on authoritarianism (concurrent-criterion validity). Its characteristics and future ways of application are discussed.

Published: June 2019

School violence among peers has serious consequences for the victims. Victimization can be direct, through physical and verbal aggression, and relational, through exclusion and social rejection. The objective of this study wasto analyze the psychometric properties of the Peer School Victimization Scale (VE-I), which consists of 11 items related to different forms of victimization. 1389 adolescents (50.45% boys) ranging from 11 to 15 years old (M = 13.37, SD = 1.23) participated in this study. The structure of the scale was analyzed by means of exploratory factor analysis and confirmatory factor analysis using two different subsamples. The results show the existence of three factors (physical victimization, verbal victimization and relational victimization), with reliability coefficients higher than ? = .70 and negative correlations with social self-concept and life satisfaction. The analyzed scale has adequate psychometric properties and can be useful in research and interventionsabout this topic.

The Job Demands-Resources model (Bakker & Demerouti, 2007) is currently an important framework in explaining health and motivational-related processes at work.The present study examined the psychometric properties ofthree scales measuring general personal resources previouslyvalidated in a sample of university students derived from the Social Cognitive theory related to the workplace: Scale of Perceived Social Support, Scale of Outcome Expectations and Scale of Goal Progress. Two hundred and twenty-three Argentinian workers participated in the study. Internal structure, criterion validity and reliability (Cronbach’s alpha and omega) were assessed. The results support the unidimensionality of the scales and theoretically relevant relations with the dimensions of burnout, engagement, positive emotions and job satisfaction as well as appropriate indicators of reliability. Practical implications of the findings are discussed.

Published: June 2019

The objective of this work was to evaluate the psychometric properties of a modified version of the Motivational Regulation Strategies Questionnaire of Wolters and Benzon (2013) in a sample of Argentinian university students. Thirty bilingual students answered the instrument in English and Spanish and the equivalence of the translation was analyzed. Spearman’s correlations between the original and the translated version were strong (.71 to .90), which showed the equivalence. Then, the adapted questionnaire (N = 329) was administered and its internal structure and internal consistency were analyzed. The exploratory factor analysis showed a questionnaire consisting of 37 items and eight factors. The scales showed good internal consistency indexes (? = .68 to ? = .95). The questionnaire evaluates value regulation, situational interest regulation, performance-approach regulation, performance-avoidance regulation, mastery-approach regulation, mastery-avoidance regulation, self-consequence, environmental structuring. The results and the need for new psychometric studies are discussed.

Published: June 2019

Hace algunas décadas, la esperanza disposicional se propuso como un constructo bifactorial. Sin embargo, evidencia reciente sugiere que podría entenderse mejor con un modelo unifactorial. En el presente estudio, mediante análisis factoriales confirmatorios se probó el ajuste de estructuras unifactoriales, con dos factores correlacionados, con dos factores más un factor de segundo orden, y bifactor, de la Escala de Esperanza Disposicional para Adultos (Snyder et al., 1991), traducida al español y adaptada a la poblaciónparaguaya. Se realizó el cuestionario a 219 estudiantes universitarios de Paraguay (edad promedio de 23 años; DE = 3.717; 55 participantes de sexo masculino y 163 de sexo femenino). Los resultados indican un excelente ajustepara los tres modelos, considerándose preferible el modelo bifactor debido a que los índices complementarios indican que la escala es primariamente unidimensional. La escala demuestra propiedades psicométricas adecuadas para su uso en poblaciones latinoamericanas.
