Aspectos inmunológicos del pénfigo: relación de dos casos
Authors: Barba Sergio , Vivar Nicolas , Borja Julio , García Marco 
Published: January 2021

Presentamos dos casos de pénfigo foliáceo diagnosticados en base al cuadro clínica, exámenes de laboratorio inmunológico e inmunofluorescencia de los cortes de piel afectada. Lo más llamativo de estos casos es el aumento neto de gemma-globulinas, especialmente de IgG, la poca afectación sobre el sistema del complemento, la ausencia de anticuerpos anticomponentes nucleares y citoplasmáticos celulares, asàcomo muy probable depresión cualitativa y/o cuantitativa de la respuesta inmune celular.
Se hacen algunas especulaciones acerca del origen infeccioso de la enfermedad, probablemente con la participación de ciertos tipos de virus “lentos” que actuando sobre un sistema inmunológico alterado producirían la enfermedad activa.
También compararemos los resultados de dos esquemas de tratamiento; uno que hemos denominado “conservador” que contempla la eliminación de las ampollas, manejo metabólica, híbrido, electrolítico correctos, con medidas profilácticas para evitar infecciones sobreñadidas, como si tratara de una quemadura superficial extensa y que nos ha dado buenos resultados; y otro esquema, “clásico”, usando esteroides e inmunosupresores, que es muy peligroso y que quizá contribuyó a producir la muerte a una paciente con probables alteraciones inmunológicas profundas
Valores de algunas determinaciones inmunológicas normales en nuestro medio
Authors: Barba Sergio , Proaño Victor , Carrera Alfredo 
Published: January 2021

Se analizan 678 determinaciones inmunológicas en personas sanas o con otras afecciones sin compromiso inmunológico, que concurren al Hospital General de las Fuerzas Armadas, de Quito.
Por el método de inmunodifusión radial se dosifican las inmunoglobulinas G, A y M en el suero ; IgA en saliva; valores de C3 y alfa-1 antitripsina en el suero.
Los valores obtenidos tienen buena correlación estadística y se les ha clasificado en tres grupos de edades: de 0-12; de 13-60 años y de más de 60, en relación a épocas de la vida influyentes en la madurez inmunológica de las personas. Estos demuestran que los límites inferiores de las cifras son mayores en nuestra población en la determinación de inmunoglobulinas, complemente, alfa-1 antitripsina. Los valores altos son concordantes con los de referencia internacional.
Síndromes RINO-SINU-BRONQUIALES en el Ecuador
Authors: Barba Sergio 
Published: January 2021

Se hace un estudio tendiente a individualizar los llamados síndromes rino-sinu-bronqueales y a establecer las semejanzas y diferencias con el asma clásica de tipo alérgica. Se dice que son alteraciones de las vías respiratorias que tienen como origen alteraciones de las vías respiratorias altas que se complican frecuentemente en problemas broncoespásmicos que le dan características especiales y muy frecuentemente con problemas broncoespásmicos que le dan características especiales y muy frecuentemente confundidas con el asma. La padecen especialmente los niños, con alguna preferencia atópicos, que no presentan mucha positividad en sus estudios alergológicos, pero que en las pruebas espirométricas demuestran alteraciones del VEF de 0 a 25 primero y más tarde del 25 a 75, dándole características obstructivas mixtas: de tipo central y periférico. Esto también se demuestra en las curvas flujo-volumen con la disminución del volumen Peak. Se hacen algunas consideraciones de etiopatogenia, las cuales confluyen hacia el síndrome de hiperreactividad bronquial que está estudiándose ampliamente en este tiempo. También se notan algunas acotaciones respecto al tratamiento, y pronóstico de enfermedad.
La asociación sulfanamida- trimetoprim en infecciones experimentales con Clostridium septicum
Authors: Soria Carlos 
Published: January 2021

Infecciones experimentales con C. septicum en ratones sirvieron para estudiar comparativamente el efecto quimoterapéutico de soluciones con sulfametaxozole, sulfadiazina o sulfadoxina, en asociación con trimetoprim. Se estudió el efecto de algunas vías de administración terapéutica asàcomo las dosis óptimas y la influencia del número de dosis de cada tratamiento en el curso de infecciones letales. Se observó la influencia de la edad y peso de los animales confrontados, asàcomo el tiempo de la infección transcurrido antes del tratamiento. Los resultados obtenidos demuestran la efectividad de estos quimoterápicos de amplio espectro en el control de infecciones letales con C. septicum. Esta efectividad parece depender del inoculum de confrontación usado, de la edad y peso de los animales huéspedes, del tiempo de la infección transcurrida antes del tratamiento, asàcomo de la vía de administración y del tipo de tratamiento de usado. Una combinación cuidadosa de estos parámetros, especialmente cuando se usó al asociación de estos parámetros, especialmente cuando se usó la asociación terapéutica sulfadoxina-trimetoprim por la vía intramuscular, dio como resultado altos números de sobrevivencia ante infecciones que en animales controles resultaron ser letales. Se discute el significado de estas observaciones en términos del curso de la infección bacteriana dependiente del mecanismo de acción de cada asociación terapéutica estudiada
Coal ash Portland Cement Mortars Sulphate Resistance
Authors: Menéndez Esperanza , Argiz Cristina , Sanjuán Miguel Ángel 
Published: January 2021

Coal fly ash (CFA), coal bottom ash (CBA) are residues produced in thermo-electrical power stations as result of the coal combustion in the same boiler. Therefore, some characteristics of the coal fly ash (CFA) are comparable with those of the coal bottom ash (CBA). Nevertheless, coal bottom ash size is larger than coal fly ash one. Consequently, it was found that it is necessary to grind the coal bottom ash (CBA) to reach a similar size to that one of the CFA. The objective of this paper is to evaluate the performance of Portland cement mortars made with coal fly ash (CFA), coal bottom ash (CBA) or mixes (CFA+CBA), against sulphate attack. The methodology is based on the expansion of slender bars submerged in a sodium sulphate solution (5%) according to the ASTM C-1012/C1012-13 standard. It has been found that mortars elaborated with CEM I 42.5 N (without ashes) presented the largest expansion (0.09%) after a testing period of 330 days. Mortars made with CEM II/A-V exhibited lower expansion (0.03%). Summing up, it can be established that mortar expansion decreases when the coal ash amount increases, independently of the type of coal ash employed. The novelty of this paper relies on the comparison between the performances of Portland cement mortars made with coal fly ash (CFA) or coal bottom ash (CBA) exposed to external sulphate attack.

Prediction of Compressive Strength of Self-Compacting Concrete (SCC) with Silica Fume Using Neural Networks Models
Authors: Serraye Mahmoud , Kenai Said , Boukhatem Bakhta 
Published: January 2021

Self-Compacting Concrete (SCC) is a relatively new type of concrete with high workability, high volume of paste and containing cement replacement materials such as slag, natural pozzolana and silica fume. Cement replacement materials provide a wide variety of benefits such as lower cost, reduced consumption of natural resources, reduced carbon dioxide emissions and improved fresh and hardened properties. SCC is used in many applications such as sections with congested reinforcement and high rise shear walls and there is a need for the prediction of the performance of SCC used. Artificial Neural networks (ANN) are widely used in civil engineering for the prediction of the performance of some engineering materials such as compressive strength and durability. However, currently, studies on SCC containing silica fume are very rare. In this paper, an artificial neural networks (ANN) model is developed to predict the compressive strength of SCC with silica fume using the Levenberg-Marquardt back propagation algorithm based on a database from 366 experimental studies. The model developed was correlated with a nonlinear relationship between the constituents (input) and the compressive strength of SCC (output). To evaluate the predictive ability and generalize the developed model, other researchers’ experimental results were compared with the model prediction and good agreements are found. A parametric study was conducted to study the sensitivity of the ANN proposed model to some parameters such as water/binder ratio and superplasticizer content. The model developed in this study can potentially be used for SCC compressive strength prediction with very acceptable results and a high correlation coefficient R2=0.93. The developed model is practical, easy to use and user friendly. Doi: 10.28991/cej-2021-03091642 Full Text: PDF

Authors: Sujatha A. , Govindaraju L. , Shivakumar N. , Devaraj V. 
Published: January 2021

Proper design of roads and airfield pavements requires an in-depth soil properties evaluation to determine suitability of soil. Soft computing is used to model soil classification system's dynamic behaviour and its properties. Soft computing is based on methods of machine learning, fuzzy logic and artificial neural networks, expert systems, genetic algorithms. Fuzzy system is a strong method for mimicking human thought and solves question of confusion. This paper proposes a new decision-making approach for soil suitability in airfield applications without a need to perform any manual works like use of tables or chart. A fuzzy knowledge - based approach is built to rate soil suitability in qualitative terms for airfield application. The proposed model describes a new technique by defining fuzzy descriptors using triangular functions considering the index properties of soils as input parameters and fuzzy rules are generated using fuzzy operators to classify soil and rate its suitability for airfield applications. The data obtained from the results of the laboratory test are validated with the results of the fuzzy knowledge-based system indicating the applicability of the Fuzzy model created. The approach developed in this work is more skilled to other prevailing optimization models. Due to its system’s flexibility, it can be suitably customized and applied to laboratory test data available, thus delivering a wide range for any geotechnical engineer.

Published: January 2021

One of the most important aspects of managing a project is communication. Although this issue has been widely covered in management, a lack of attention has been given in the project management, slight is known as the impact of social media tools on construction project management. The main purpose of the present study is to explore the potential of social media for the construction of the project management and to understand some of the difficulties that arise from social media implementation. For this purpose a 12 question and 20-item questionnaire has been employed and distributed as a soft copy questionnaires among the sample of 400 engineers who work in the construction field, either in the private sector including contracting and consulting companies (grade one and two) or in the public sector in Jordan. The number of participants who said that they apply social media tools in their projects was 357, while 43 participants, were eliminated as they do not apply social media tools in their work. The collected data from 375 participants were analyzed by using the Statistical Package for Social Sciences (SPSS). The results indicated that there is a positive impact of social media on project management and project team in construction projects especially in reducing time. Coringly, the study revealed the existing difficulties that arise from social media use in projects. The study also has concluded that using social media in the project is highly important to organize the management project recently. Doi: 10.28991/cej-2021-03091644 Full Text: PDF
Comparison of Nondestructive Testing Method for Strength Prediction of Asphalt Concrete Material
Authors: Al-Mattarneh Hashem , Dahim Mohammed 
Published: January 2021

Concrete is one of the most common construction materials used in rigid pavement, bridges, roads, highways, and buildings. Compressive strength is one of the most important properties of concrete, which determines its quality. This study aims to present the use of a new surface dielectric method to estimate concrete compressive strength. Six concrete mixtures were produced with compressive strengths ranging from 30 to 60 MPa. Compressive strength and strength development were determined during 28 days of curing. All concrete mixes were tested using the ASTM standard. The dielectric properties, ultrasound velocity, and rebound number of all concrete mixes were also measured at each day of curing. The results obtained from the proposed dielectric method in predicting the compressive strength of concrete were compared with the rebound hammer and ultrasonic velocity that are frequently used to evaluate the compressive strength of concrete. The dielectric method shows a higher square correlation coefficient than the other two methods. The results also indicate that combined more than one method of nondestructive techniques will lead to higher prediction and could help to reduce some errors associated with using a certain method alone. The result indicate that the finding of this study could lead to help in reducing the time of evaluating concrete during construction and could also provide tools for practicing engineer to take decision faster with more confidence level on quality of concrete.

“RAMANUJAN’S CONGRUENCES AND DYSON’S CRANK”
Authors: Das Sabuj 
Published: January 2021

In 1944, Freeman Dyson conjectured the existence of a “crank” function for partitions that would provide a combinatorial result of Ramanujan’s congruence modulo 11. In 1988, Andrews and Garvan stated such functions and described the celebrated result that the crank simultaneously explains the three Ramanujan congruences modulo 5, 7 and 11. Dyson wrote the article, titled Some Guesses in the theory of partitions, for Eureka, the undergraduate mathematics journal of Cambridge. He discovered the many conjectures in this article by attempting to find a combinatorial explanation of Ramanujan’s famous congruences for P (n), the number of partitions of n indeed, Ramanujan’s formulas lay unread until 1976 when Dyson found In the Trainty College Library of Cambridge University among papers from the estate of the late G.N.Watson. In 1986, F.Garvan wrote his Pennsylvania state Ph.D. Thesis Precisely on the formulas of Ramanujan relative to the crank. In view of this theoretical description, the story of the crank is a long romantic tale and the crank functions are intimately connected to all partitions congruences. In 2005, Mahlburg stated that the crank functions themselves obey Ramanujan type congruences.

Published: January 2021

Polycystic Ovary Syndrome (PCO) is an endocrine disease that is characterized by a set of symptoms including irregular menstruation, subfertility, skin changes, hirsutism and weight gain.
The pathogenesis of PCO is mostly related to increase androgens and insulin resistance. Treatment is mostly symptomatic hence metformin is being used due to its effect in decreasing gluconeogenesis and by increasing peripheral utilization of glucose, in addition to its lowering effects on androgen. Thus, Metformin role in PCO treatment ranges between managing insulin resistance, promoting ovulation and treating hirsutism to some extent. Some studies showed that Metformin is effective in lowering body weight in PCO patients, yet it is not being indicated officially for this purpose.
Background: Metformin is expected to have an effect of weight reduction in PCO patients This is the scope of this research which intends to explore this action.
Method: The Study design is cross sectional study using online questionnaire. Open and closed ended questions were included.
Results: Based on the results the majority shows decrease in the weight, while only one reported increase in their weight and only one had the same weight during and after treatment with metformin.
Conclusions: Metformin generally showed positive effect regarding reducing the body weight of the females diagnosed with polycystic ovarian syndrome when used alone.

In 2013, Andrews, Garvan and Liang defined Self-conjugate S-partitions. In 2011, Andrews stated the definition of spt(n). This paper shows how to find the Self-conjugate S-partitions of 4 and 5 respectively, and proves the Corollary-1 that is ‘The number of Self-conjugate S-partitions counted according to the weight w is congruent to the total number of smallest parts in all the partitions of n modulo 2’. This paper shows how to generate the generating functions for Msc(n) in different ways. This paper shows how to find the number of partitions of n with an odd number of smallest parts and a total number of even (respectively odd) parts, and shows how to find the number of partitions of n in odd parts without gaps, and also shows how to generate the generating functions for and respectively. This paper shows how to prove the further three Corollaries with the help of examples, and shows how to prove the three Theorems by easy algebraic method.
CREATIVITY IN VISUAL ART
Authors: Singh Chauhan Bijender 
Published: January 2021

This paper examines the nature of creativity in visual art. Creativity requires originality and effectiveness in the work of art whether it is a design or a painting. Originality is undoubtedly required. It is often labeled novelty, but whatever the label, if something is not unusual, novel or unique, it is commonplace, mundane or conventional. It is undoubtedly cannot be called creative work.
According to my opinion, creativity requires confluence of some instinct like intellectual abilities, knowledge, and style of thinking, personality, motivation and environment. It varies across time and place but nature of creativity essentially the same around the globe.
The role of gut microbiota in health and diseases
Authors: Fetarayani Deasy , Hariyono Handoko , Soegiarto Gatot 
Published: January 2021

ABSTRACTABSTRACTMicrobiota contributes a crucial part in the human hosts' health and actively provides to the emergence of various diseases. The optimal composition of healthy intestinal microbiota varies from person to person. The more various and abundant of the microbiota, the greater their resistance to outside hazards. Colonization of the microbiota in the human body starts after delivery and develops continuously from infant to adult. The largest microbial colony is constructed in the lower part of the adult human digestive tract. The composition of the human intestinal microbiota alters promptly during the beginning of life and is steady. It has been described the close relationship among dysbiosis of the intestinal microbiota with intestinal and non-intestinal diseases. Nevertheless, it is uncertain whether dysbiosis is the culprit of the disease or only as a result of the disease. Human microbiota's role must be investigated more deeply so that later it can be developed for the prevention, diagnosis of disease, and more effective treatment strategies in the future. In this minireview, we will describe the development of the gut microbiota, its interaction with our bodily systems and defense, the multiple causes of dysbiosis, and its impact on several metabolic in inflammatory diseases in humans. With this insight, it is hoped that we can be more cautious about using antibiotics, avoid things that lead to dysbiosis, and handle diseases more holistically, putting the balance of the microbiota into account.

Der „Mantel des Paulus“ (2 Tim 4,13): vergessen, zurückgelassen, deponiert?
Authors: Schramm Christian 
Published: January 2021

Abstract
The short demand to bring Paul’s coat in 2 Timothy 4:13 has been a part of exegetical discussion for a long time. Especially the intention, the text pragmatics and the meaning of this verse are a matter of academic dispute. The point is: The interpretation of this verse has an important impact on the question of the authentic or pseudepigraphic character of 2 Tim. The following article focusses on an aspect that hasn’t been looked at much so far: the legal business of depositum as a possible historical backdrop. A third person’s (i.e. Timothy’s) mandate to pick up something deposited tells us much about his legitimacy as an authorized representative of the person who made the depositum (i.e. Paul). And possibly we also learn something about 2 Tim: 2 Tim as a letter could function as an authorizing document for the person sent out to pick up the coat – then 2 Tim 4:13 would work as a kind of certificate of authenticity of 2 Tim as an allegedly original Pauline letter.
