El objetivo del trabajo de investigación fue evaluar la utilidad de la amilasa y lipasa sérica en el diagnóstico ycontrol de tratamiento de pacientes con dolor abdominal agudo de origen pancreático y no pancreático que acudieronal Hospital NORTHOSPITAL de Quito durante el periodo comprendido entre octubre a diciembre del 2015y que presentaron valores elevados de amilasa y lipasa sérica. Las variables edad, sexo, antecedentes patológicosy familiares, motivo de consulta, signos y síntomas, pruebas de laboratorio e imagen, diagnóstico y tratamientofueron obtenidas de las historias clínicas. Para el tratamiento estadístico se emplearon herramientas como: media,frecuencia, sensibilidad, especificidad, valor predictivo positivo (VPP), valor predictivo negativo (VPN), curvasROC, prueba t para muestras relacionadas y ANOVA de un factor. Utilizando pruebas estadísticas de rigor se evidencióque la lipasa sérica presenta una mayor sensibilidad (90,91%) frente a la amilasa (63,3% de sensibilidad)para el diagnóstico de pancreatitis. Ambos parámetros bioquímicos ofrecen un 100% de especificidad. La amilasay lipasa sérica se elevan en el curso de una pancreatitis aguda y en otras patologías no pancreáticas, por lo tantose precisa de otros exámenes de laboratorio y pruebas de imagen para logar un diagnóstico eficaz.
Poder, memoria y trabajo intelectual
Authors: Rodríguez Albán Martha
Published: September 2019

En este artículo, la autora actualiza la reflexión sobre la noción gramsciana de intelectual orgánico. Más allá de los lugares comunes, eso lleva a pensar el trabajo intelectual desde su incrustación en las relaciones sociales, desde su rol productivo de estructuras ideológicas, políticas y económicas. Es decir, permite pensar el trabajo intelectual como constructor de relaciones de poder y/o dominación. Por otro lado, hace hincapié en el hecho de que la escritura no es una condición indispensable para el cumplimiento del trabajo intelectual, como lo muestran experiencias de intelectuales indígenas y fronterizos del CRIC colombiano. Dichos intelectuales apoyan proyectos emancipadores fundados en la restitución de su memoria política. Entonces, más allá de las identidades colectivas construidas por las academias del norte y por los intelectuales tradicionales, hay también proyectos que redefinen identidades y utopías emancipadoras en tiempos de modernidades y posmodernidades desiguales.

Authors: Guevara Collazos Aura Jessica , Villagran Munar Edwin Andres , Velasquez Ayala Fabian Andres , Gonzalez Velandia Kristle Danitza
Published: September 2019

La producción de uchuva (Physalis peruviana L.) en Colombia tiene un alto interés socioeconómico por su potencial comercial y el amplio número de productores de pequeña escala que integran el sistema productivo. Las zonas de cultivo en Colombia están localizadas en los pisos térmicos fríos de los departamentos de Boyacá, Cundinamarca y Antioquía. Recientemente, con el fin de buscar la sostenibilidad en la producción agrícola, la producción agroecológica ha tenido un creciente aumento en las zonas donde se establece este tipo de cultivo. Por lo tanto, el objetivo de esta investigación fue evaluar y comparar los comportamientos postcosecha del fruto de uchuva, obtenido bajo dos sistemas de producción agrícola (convencionales y agroecológicos) establecidos bajo condiciones climáticas de la sabana de Bogotá. La metodología consistió en la medición y cuantificación de las principales variables fisicoquímicas: peso, diámetro ecuatorial, firmeza, pH, sólidos solubles totales, acidez, respiración y pérdida de peso durante los distintos estados de madurez. Estos valores fueron comparados en referencia a lo establecido en la NTC 4580. Los resultados obtenidos para cada propiedad mostraron diferencias significativas entre cada sistema productivo y cada estado de madurez evaluado, encontrando una sensibilidad más elevada al deterioro postcosecha en los frutos obtenidos mediante producción agroecológica.

Authors: Medina-García Guillermo , Grageda-Grageda José , Ruiz-Corral José Ariel , Casas-Flores José Israel , Rodríguez-Moreno Víctor Manuel , De la Mora-Orozco Celia
Published: September 2019

En México los frutales caducifolios se cultivan en el centro y norte del país donde la temperatura, al final del otoño y durante el invierno, es baja para que ocurra una defoliación de los árboles y presenten un letargo durante el invierno. El calentamiento global, como efecto del cambio climático, tiene el potencial de reducir el frío disponible en el invierno y afectar la producción de los árboles frutales caducifolios. El objetivo de este trabajo fue conocer el efecto del cambio climático, sobre la acumulación de horas frío en el periodo de invierno. Se realizó un análisis histórico sobre la variación del número de horas frío (HF) y un análisis similar en los escenarios climáticos 2030, 2050 y 2070 en los RCP 4.5 y 8.5. Tanto en el análisis histórico como en los escenarios se encontraron efectos del cambio climático, el cual será desfavorable para los frutales de clima templado. El calentamiento global provocará una disminución de la superficie con acumulación de 600 a 800 HF de 11.7, 25.8 y 33% en los escenarios climáticos 2030, 2050 y 2070 del RCP 4.5, respectivamente y hasta 99.5% la superficie con acumulación de 800 a 900 HF en el clima 2070 del RCP 8.5. En cambio, la superficie con poca acumulación de HF (50 a 200) aumentará 11.5, 29.3 y 36.4% en los escenarios climáticos 2030, 2050 y 2070 del RCP 4.5, respectivamente. Los frutales caducifolios en el futuro se verán limitado por la disminución de HF, en las áreas con mayor acumulación de frío, de igual manera pueden ser afectados los cereales de otoño-invierno.

Authors: Hernández David Cadena , Ariza Roberto Gaxiola , Mora Avilés María Alejandra
Published: September 2019

El gen Arabidopsis Vacuolar Pyrophosphatase-1 (avp1) por sus siglas en inglés, el cual codifica a la enzima H+ pirofosfatasa mejora la tolerancia a sequía y salinidad e incrementa la biomasa y rendimiento cuando se sobreexpresa en plantas transgénicas. El propósito de este estudio fue analizar las características fenológicas, fisiológicas y agronómicas del frijol cv. Pinto Saltillo (PS) transformado con el gen 35Sprom:avp1 bajo condiciones de estrés hídrico extremo. El diseño experimental consistió en una distribución aleatoria de 10 plantas homocigotas por cada una de las 9 líneas PS-avp1, así como plantas control no modificadas. El riego fue suspendido en la etapa fenológica de 50% de floración y el estrés hídrico inició a partir del 100% hasta 9% de contenido volumétrico de agua (CVA), a lo largo de 10 días. Los resultados mostraron que el índice de intensidad de sequía (IIS) fue de 0.78. Aun cuando la conductancia estomática y la transpiración mostraron una tasa de disminución similar a las plantas no transformadas, la tasa fotosintética de todas las líneas PS-avp1 fue superior a las plantas control bajo condiciones de estrés hídrico. El aumento de la biomasa total en algunas líneas PS-avp1 no correlacionó con un rendimiento mayor. Siete de las nueve líneas evaluadas mostraron un mayor rendimiento (35% - 96%) comparadas con las plantas PS no transformadas bajo condiciones de estrés, indicando una mayor eficiencia en la translocación de fotoasimilados a los órganos destino (semillas).
Differences at the Extremes? Gender, National Contexts, and Math Performance in Latin America
Authors: Liu Ran , Alvarado-Urbina Andrea , Hannum Emily
Published: September 2019

Studies of gender disparities in STEM (science, technology, engineering, and mathematics) performance have generally focused on average differences. However, the extremes could also be important because disparities at the top may shape stratification in access to STEM careers, while disparities at the bottom can shape stratification in dropout. This article investigates determinants of gender disparities in math across the performance distribution in Latin American countries, where there is a persistent boys’ advantage in STEM performance. Findings reveal disparate national patterns in gender gaps across the performance distribution. Furthermore, while certain national characteristics are linked to gender gaps at the low- and middle-ranges of the performance distribution, female representation in education is the only characteristic associated with a reduced gender gap at the top level.

Authors: Kuprina N. I. , Kochetova O. A. , Shilov V. V. , Ulanovskaya E. V.
Published: September 2019

Introduction. Professional polyneuropathy of the upper extremities is an example of the most common pathology due to physical overload and functional overstrain of the muscles of the upper extremities.

The aim of the study was to study the ultrasound quantitative parameters of the anatomical structures of the arteries in normal and professional polyneuropathy.

Materials and methods. Patients with polyneuropathy from physical overloads and functional overvoltage in hospital were examined by ultrasound in B-mode. The results of ultrasonic assessment of the morphological state of the main arteries of the forearm in professional polyneuropathy from physical overload and functional overvoltage are presented. The criteria for the selection of patients in the study were: the presence of severe clinical manifestations of polyneuropathy, confirmed by instrumental methods of the study, the data of sanitary and hygienic characteristics of working conditions, indicating contact with physical overload in the workplace, the absence of chronic diseases of the cardiovascular system (coronary heart disease, rheumatic, oncological, infectious diseases, heart defects, arrhythmias and conduction).

Results. The study of ultrasound morphological features of the arteries of the upper extremities in professional polyneuropathy showed an increase in the intima-media complex, compaction of the structure of the vascular wall equally in the radial and ulnar arteries. The revealed changes were determined with the same frequency in men and women. The study of the right and left hands showed the presence of more pronounced changes on the side of the «working hand».

Conclusions. Today the method of ultrasound examination of the main arteries of the middle caliber of the upper extremities is the only available and objective method of studying the morphological changes of the vascular system in professional polyneuropathy from functional overvoltage and physical overload. In comparison with the control group in patients with polyneuropathy, a significant decrease in the diameter of the vessels was determined on the limb, which has a predominant load. Ultrasonic changes are detected at the initial stages of professional polyneuropathy of the upper extremities.
Technology integration in education: Effectiveness, pedagogical use and competence
Authors: Pittas Evdokia , Adeyemi Adenike
Published: September 2019

This cross-sectional study examined primary and secondary teachers’ and students’ views regarding technology integration into teaching and learning in Muscat, Oman. The target group consisted of teachers (N=44) and students (N=219) from two bilingual and two international schools in Oman. Results showed that the majority of students use technology to do projects and research. Both teachers and students enjoy the use of technology in teaching and learning, they feel competent in using it and they similarly evaluate the effectiveness of available technologies. Although the majority of teachers agreed that teaching has become easier and faster with technology, only a small percentage integrates technology into teaching. Factors hindering technology integration concern curriculum design, network issues, time constraint and other. In theory, the study contributes to our understanding of the reasons why teachers’ and students’ find it challenging to use technological innovations in school. Methodologically, this study provides the basis for examining Technological Pedagogical Knowledge in certain socio-geographical contexts. In practice, the study provides educational authorities with suggestions on how technology can be used to support, enhance and extend the curriculum.
Cones, needles and wood: Micraspis (Micraspidaceae, Micraspidales fam. et ord. nov.) speciation segregates by host plant tissues
Authors: Quijada L. , Tanney J.B. , Popov E. , Johnston P.R. , Pfister D.H.
Published: September 2019

Micraspis acicola was described more than 50 years ago to accommodate a phacidium-like fungus that caused a foliar disease of Picea mariana. After its publication, two more species were added, M. strobilina and M. tetraspora, all of them growing on Pinaceae
in the Northern Hemisphere, but each species occupying a unique type of host tissue (needles, cones or wood). Micraspis is considered to be a member of class Leotiomycetes, but was originally placed in Phacidiaceae (Phacidiales), later transferred to Helotiaceae
(Helotiales) and recently returned to Phacidiales but in a different family (Tympanidaceae). The genus remains poorly sampled, and hence poorly understood both taxonomically and ecologically. Here, we use morphology, cultures and sequences to provide insights
into its systematic position in Leotiomycetes and its ecology. Our results show that the genus should not be included in Tympanidaceae or Phacidiaceae, and support the erection of a new family and order with a unique combination of morphological features supported by
molecular data.
Piloerection is not a reliable physiological correlate of awe.
Authors: McPhetres Jonathon , Shtulman Andrew
Published: September 2019

In scientific and popular literature, piloerection (e.g. goosebumps) is often described as being related to the experience of awe, though this correlation has not been tested empirically. Using two pre-registered and independently collected samples (N = 233), we examined the objective physiological occurrence of piloerection in response to awe-inducing stimuli. Stimuli were selected to satisfy three descriptors of awe, including perceptual vastness, virtual reality, and expectancy-violating events. The stimuli reliably elicited self-reported awe to a great extent, in line with hypotheses. However, awe-inducing stimuli were not associated with the objective occurrence of piloerection. While participants self-reported high levels of goosebumps and “the chills,” there was no physical evidence of this. These results suggest that piloerection is not reliably connected to the experience of awe—at least using stimuli known to elicit awe in an experimental setting.
Inquiry-Based Learning For All: A Systematic Review of the Effects of Inquiry-Based Learning on Knowledge, Skills, Attitudes and Behavior of Students with Social-Emotional and Behavioral Difficulties in Primary and Secondary Education
Authors: Zweers Inge , Huizinga M. , Denessen Eddie , Raijmakers Maartje Eusebia Josefa
Published: September 2019

Inquiry-Based Learning (IBL) has internationally been recommended as an effective method to achieve learning goals for students in elementary education. On the condition that students are provided with adequate teacher guidance during IBL, they learn more than students who are taught the same content with explicit instruction. Yet, it is unknown whether IBL is also effective for specific student populations, such as students with social-emotional and behavioral difficulties (SEBD), as these students struggle with skills that are required for IBL. We conducted a systematic review to examine what is known about the use of IBL instructional methods and its adjustments for students with SEBD and whether this instructional method is effective to achieve learning goals with this specific student population. Results showed that IBL is applied for students with SEBD, and that teachers play an important role in making adjustments in terms of teacher guidance and differentiation. IBL instruction is, however, often used and adjusted for students with various disabilities in inclusive classrooms – and not for students with SEBD specifically. Consequently, it is difficult to pinpoint which specific adjustments to IBL instruction are needed for students with SEBD in particular. It seems that the field of IBL for specific student populations is in its infancy. Yet, the available predominantly practice-based research yields sufficient indications to consider IBL instruction as a method to achieve learning goals for students with various social-emotional and academic needs.
Choose your own risks: measuring risk-taking through an interactive novel
Authors: Bran Alexandre , Vaidis David C.
Published: September 2019

We present elements that support the use of interactive novels as a relevant risk-taking measure instrument. In the introduction, we describe what interactive novels are and how they can be used to study human decision making. Then, we present the results of a study designed to assess how behaviours made in interactive novels relate to real-life behaviours. Participants (n = 234) interacted with a novel depicting a student party. During the story, participants could make several risk-taking behaviours (i.e., drug taking). Then, participants completed the Dohmen’s one item risk-taking scale, the DOSPERT scale, and a self-report risk-taking scale. Our results show strong correlations between risk-taking in the interactive novel and real life risk-taking behaviours. Notably, risk-taking behaviours made in the novel were globally more correlated with real-life risk-taking than were the Dohmen and DOSPERT scales. This supports the use of interactive novels as an instrument to study risk-taking behaviours and decision making.

Isotopic composition of water of salt lakes in Eastern Transbaikalia
Authors: Borzenkо Sv. V.
Published: September 2019

The isotope composition of the natural waters of the Eastern Transbaikalia is studied. It is established that the water of the soda lakes is more enriched with oxygen-18, but in smaller - with deuterium. It is shown that the enrichment of the waters of salt lakes with heavy isotopes is due not only to the evaporation process, but to the interaction of water with the rock. The participation of the reactions of hydrolysis of alumosilicates in the fractionation of oxygen is confirmed by the direct dependence of the magnitude of the oxygen shift on pH, the value of which depends on the degree of such interaction.

Rosmarinik Asit (RA) birçok bitki türünde bulunan önemli bir fenolik bileşiktir. Çalışmada RA’nın, A549 (İnsan Akciğer Kanser Hücre Hattı) ve Beas-2B (İnsan Sağlıklı Bronşial Epitel Hücre Hattı)  hücrelerinde, Cisplatin tarafından oluşturulan sitotoksik, genotoksik etki ve oksidatif strese karşın etkinliğinin in vitro olarak belirlenmesi ve böylelikle Cisplatin kemoterapisi sırasında hastalar tarafından kullanılabilecek RA içerikli bitkisel ürünlerin Cisplatin tedavisi üzerindeki olası etkilerinin belirlenmesi amaçlanmıştır. Bu amaca yönelik olarak sitotoksite belirlenmesinde XTT, genotoksite belirlenmesinde Komet ve oksidatif stres değerlerinin belirlenmesinde ise DCFH-DA yöntemleri kullanılmıştır. Yöntemlerde hücreler Cisplatin’in iki farklı dozuna (11, 22 µM) 24 saat süre ile maruz bırakılmıştır. Hücreler RA’nın üç farklı konsantrasyonuna (50, 100, 200 µM) hem tek başına hem de Cisplatin’in iki farklı dozu ile beraber uygulanarak 24 saat süre ile maruz bırakılmıştır. Sonuç olarak Cisplatin dozları tarafından arttırılan; sitotoksik etkiye karşın RA’nın kullanılan konsantrasyonlarının antisitotoksik aktivite, genotoksik etkiye karşın ise antigenotoksik aktivite gösterme potansiyeli olduğu belirlenmiştir. RA’nın bu aktivitelerinin temelinde de Cisplatin tarafından arttırılan oksidatif stres parametrelerini azaltıcı antioksidan özellik göstermesi olduğu belirlenmiştir. Sonuç olarak RA içeren bitkisel ürünlerin, özellikle Cisplatin kemoterapisi alan hastalarda bilinçsizce tüketiminin önlenmesi gerekliliği gösterilmiştir.

A Review on Hydrodynamical Stability of Thin Film Flowing Along an Inclined Plane
Authors: CHATTOPADHYAY Souradip , MUKHOPADHYAY Anandamoy , BARUA Amlan
Published: September 2019

The dynamics and stability of thin liquid films have fascinated scientists over many decades. Thin film flows occur over a wide range of length scales and are central to numerous areas of engineering, geophysics and biophysics. These include nanofluidics and microfluidics, lava flows, coating flows, tear-film rupture, dynamics of continental ice sheets and surfactant replacement therapy. Study of falling film instability has its wide applications in the practical field of industry and engineering. Practical applications in industrial processing motivate the recent research to investigate the factors which may affect the formation of waves on the surface of the coating layers and/or to determine the ways to overcome or to minimize the unwanted factors within the desired limit of tolerance. The dynamics of a liquid film flowing down a plane under the action of gravity is a problem which appears in many technological and natural systems, namely large scale geophysical environments such as lava flows or spillways, daily life scenarios such as water flowing down a window pane or a slippery road on a rainy day, chemical engineering processes such as evaporators, heat exchanges and falling film reactors or surface coating. The aim of this paper is to throw light on the studies conducted on hydrodynamical stability.

Background: The management of Guillain-Barré Syndrome is very crucial for the outcome of the patient.

Objective: The aim of the study was to compare efficacy of IvIg(Intravenous Immunoglobulin) versus PE(Plasmaexchange) in treatment of mechanically ventilation adults with GBS in neuro-intensive care unit of Bangladesh.

Methodology: Thiswas a prospective, observationalcohort study, in a Neuro-ICU from 2017 to 2018. We included all patients with GBS who required mechanical ventilation (MV). We defined two groups: group 1 (group treated by IvIg: 0.4 g/kg/day for 5 days) and group 2 (group treated by PE: 5 PE during 10days, every alternate day). We collectedclinical and therapeutic aspects and outcome.

Results: A total number of 49 patients (34 in group 1 and 15 in group 2) were enrolled. The mean age was 37.4±9.2 years, with a male predominance (65.3%). on electrophysiological findings, in 4(32.7%) patients had acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and acute motor axonal neuropathy (AMAN) in 26 (53.1%) patients and acute motor-sensory axonal neuropathy (AMSAN) was 3(6.1%)and NCS was not done in 4(8.2%) cases. The mean length of ICU stay was 20±19.10 days and 46.60±30.02 days in IVIG and PE group respectively. The ICU stay was significantly shorter (p = 0.001) in the IvIg group than PE group. Patients receiving IvIg were early weaned of MV (p = 0.002) compared to those receiving PE with a statistical significance. Also, duration of M/V (P=.002), Need of tracheostomy (p=.005) and over all surval rate (p=.007) was significantly in favoue of IvIg group than PE group. Out of 49 patients, total 3 patients were died and they all were AMAN variety.

Conclusion: Our work reveals a meaningful difference for the MV duration, ICU stay, weaning and excellent recovery in IvIg group compared to PE group in terms of less complcations.

Historiallisen tiedon luonne ja historian tekstikäytänteet lukiolaisten kuvaamana
Authors: Veijola Anna , Sulkunen Sari , Rautiainen Matti
Published: September 2019

Artikkelissa tarkastellaan, millaisia historiallisen tiedon luonteen kuvauksia lukiolaiset tuottivat tutkivan historian oppimisen kurssilla sekä millaiseen tekstitoimintaan nämä kuvaukset kytkeytyivät. Aineistona tutkimuksessamme on 19 lukiolaisen tekstit, jotka on kirjoitettu viikon mittaisen tutkivan oppimisen projektin lopussa. Tutkivan oppimisen viikon pääajatuksena oli vahvistaa opiskelijoiden ymmärrystä historiallisen tiedon rakentumisen tavoista sekä historiallisen tiedon luonteesta. Tekstit on analysoitu teoriaohjautuvalla sisällönanalyysillä. Opiskelijoiden teksteissä ilmeni runsaasti tekstitoiminnan kuvausta. Erilaisten lähdeaineistojen kanssa toimiminen ja päätelmien tekeminen niiden pohjalta sai historiallisen tiedon rakentumisen prosessin opiskelijoille näkyväksi. Tekstit osoittavat myös, miten historian sisältöjen ja taitojen oppiminen yhdistyivät tutkivan oppimisen prosessissa. Historiallisen tiedon luonne näyttäytyi tutkimusprosessin jälkeen selkeästi tulkinnallisena. Artikkelissamme raportoidun oppimisprojektin haasteeksi muodostui, että lukiolaisilla ei ollut keinoja arvioida tulkintojen luotettavuutta tai totuudellisuutta
Miten tyttöjen ja poikien tehtävävalinnat yhteiskuntaopin ylioppilaskokeessa eroavat toisistaan ja mitä merkitystä asialla on?
Authors: Löfström Jan
Published: September 2019

Yhteiskuntaoppia voidaan pitää heikosti sukupuolittuneena oppiaineena, sillä perusopetuksessa tyttöjen ja poikien asenteet sitä kohtaan ovat samanlaiset ja lukiossa yhteiskuntaopin ylioppilaskokeen suorittajien sukupuolijakauma on hyvin tasainen. Yhteiskuntaoppi on kuitenkin moniaineksinen kokonaisuus: sen aiheita ovat politiikka, talous, laki ja sosiaalipolitiikka. Aikaisempien tutkimusten pohjalta voidaan olettaa, että pojilla ja tytöillä on eri tavalla kiinnostusta näihin aiheisiin. Tässä artikkelissa tutkitaan, millaisia ovat ne yhteiskuntaopin ylioppilaskokeen tehtävät, joita tytöt ja pojat ovat kokeessa valinneet selvimmin eri tavalla vuosina 2007–2014. Taloustieto osoittautuu tässä tarkastelussa alueeksi, jossa poikien ja tyttöjen valintojen erot ovat olleet selvimmät. Artikkelissa pohditaan tutkimustuloksen sanomaa sukupuolitietoisen opetuksen näkökulmasta ja muistutetaan, että oppiaineiden sukupuolittuneisuutta tutkittaessa on hyvä kiinnittää huomiota myös siihen, mitä sukupuolittuneita rakenteita oppiaineiden sisällä on.

Characteristics and Processing of Hydrogen-Treated Copper Powders for EB-PBF Additive Manufacturing
Authors: Ledford Christopher , Rock Christopher , Carriere Paul , Frigola Pedro , Gamzina Diana , Horn Timothy
Published: September 2019

The fabrication of high purity copper using additive manufacturing has proven difficult because of oxidation of the powder feedstock. Here, we present work on the hydrogen heat treatment of copper powders for electron beam powder bed fusion (EB-PBF), in order to enable the fabrication of high purity copper components for applications such as accelerator components and vacuum electronic devices. Copper powder with varying initial oxygen contents were hydrogen heat-treated and characterized for their chemistry, morphology, and microstructure. Higher initial oxygen content powders were found to not only reduce surface oxides, but also reduce oxides along the grain boundaries and form trapped H2O vapor inside the particles. The trapped H2O vapor was verified by thermogravimetric analysis (TGA) and residual gas analysis (RGA) while melting. The mechanism of the H2O vapor escaping the particles was determined by in-situ SEM heated stage experiments, where the particles were observed to crack along the grain boundaries. To determine the effect of the EB-PBF processing on the H2O vapor, the thermal simulation and the validation of single melt track width wafers were conducted along with melting single layer discs for chemistry analysis. A high speed video of the EB-PBF melting was performed in order to determine the effect of the trapped H2O vapor on the melt pool. Finally, solid samples were fabricated from hydrogen-treated copper powder, where the final oxygen content measured ~50 wt. ppm, with a minimal residue hydrogen content, indicating the complete removal of trapped H2O vapor from the solid parts.

The Information and Communication Industry (ICT) plays a very important role in the growth of any nation. Therefore, the ITC sector attracts the great attention of the researcher. Despite many breakthroughs and favorable conditions to develop, the Information and Communication Industry (ICT) of Vietnam stands in a very modest position on the world’s ICT map. Therefore, understanding and having an outlook on the performance of companies in this field contribute to the development of the ICT industry in Vietnam. For this reason, the current study is conducted with the main purpose of assessing the performance of 24 Vietnamese ITC companies over past and future periods by applying a hybrid model, including Data Envelopment Analysis (DEA) and Grey model (GM). The author used GM to forecast the future value of inputs and output over period 2018–2022, and then forecasted data is used together with the data of previous years to evaluate the performance of these companies by two models of DEA—Malmquist productivity index (MPI) model and super-SBM-model. This study proposed an approach that can be used by policymakers and decision-makers to develop policies and strategies to sustain the development of the Vietnam ICT industry.
“Hierarchy” and “Holacracy”; A Paradigm of the Hematopoietic System
Authors: Yokota Takafumi
Published: September 2019

The mammalian hematopoietic system has long been viewed as a hierarchical paradigm in which a small number of hematopoietic stem cells (HSCs) are located at the apex. HSCs were traditionally thought to be homogeneous and quiescent in a homeostatic state. However, recent observations, through extramedullary hematopoiesis and clonal assays, have cast doubt on the validity of the conventional interpretation. A key issue is understanding the characteristics of HSCs from different viewpoints, including dynamic physics and social network theory. The aim of this literature review is to propose a new paradigm of our hematopoietic system, in which individual HSCs are actively involved.
The Silence, Exile, and Cunning of “I”: An Analysis of Bildungsroman as the Place Model in the Work of Charlotte Brontë and James Joyce
Authors: White Kathryn , Ferguson Frank
Published: September 2019

Education, be that on a moral, social or intellectual level, in a formal setting or via lived experience is Bildungsroman’s raison d’être. ‘Moments of crisis’ and the resultant demonstration of the journey towards awareness of personal autonomy, agency, identity and place are discussed via geographical imagination. This article examines ‘fictional’ teachers, the impact of the ‘professional’ on formative development and how the fictional characters of Jane Eyre and Stephen Dedalus fit within and extend the Place Model.
Concentrations of PCDD/Fs in Human Blood: A Review of Data from the Current Decade
Authors: Marquès Montse , Domingo Jose L.
Published: September 2019

Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/Fs) are environmental pollutants with great persistence, the capacity of bioaccumulation, and well known important toxic effects in humans and animals. Incinerators of hazardous, municipal and medical waste, chlorine bleaching of paper pulp, cement plants, and the traffic of motor vehicles are the most frequent emission sources of these compounds. The diet, followed at a great distance by inhalation, is generally the main way of human exposure to PCDD/Fs. Human biomonitoring is of great importance to prevent potential adverse effects derived from exposure to chemicals such as PCDD/Fs. In relation to this, blood is among the most used biological monitors. In the current review, we have summarized the recent information (2000–2009) published in the scientific literature (databases: Scopus and PubMed) on the concentrations of PCDD/Fs in blood samples of non-occupationally exposed populations, as well as in some groups of occupationally exposed individuals. We have revised a number of studies conducted in various African, American, Asian and European countries, and Australia. Unfortunately, the information is quite limited. No data are available for most countries over the world. Based on the results here reviewed, where available, the current health risks for the general populations do not seem to be of concern. Moreover, taking into account the important reductions observed in the levels of PCDD/Fs in foodstuffs, new decreases in the concentrations of PCDD/Fs in blood—and other biological tissues—are very probable in the immediate years.
