Entangled in two Romance languages: Experiencing language barriers in higher education
Authors: Da Costa Dinis Fernando
Published: September 2021

Since 2002, which marks the end of the Civil War in Angola, a large multilingual and multicultural workforce from various corners of the world has entered the Angolan education system. This paper investigates language barriers experienced in the classroom of Spanish speaking lecturers by Portuguese speaking students. The study focuses on a group of 81 first year students enrolled at the Pedagogic School of Namibe (Universidade Mandume Ya Ndemufayo) and the Institute of Higher Education Gregorio Semedo. Using questionnaires and observation techniques, the article shows how Spanish poses a language barrier to efficient communication in the teaching-learning process. It also shows that students employ various strategies; from asking help from fellow colleagues to recording lectures, in order to comprehend the lecturers’ explanation. Given that the Angolan higher education system hosts a great number of foreign lecturers, largely from Cuba, the paper offers recommendations through which to lower language barriers and thus create a conducive environment for meaningful learning.

Agroforestry system has been considered as one of the effective ways of the plantation for increasing a production and securing the environment as well as plays an important role in the social and economic development. Mindi development has been widely practiced in community forests but the agroforestry system is only limited to local knowledge obtained from old generation. This causes the people's forests to tend to be unable to survive due to the demands of the people's food needs. Arrowroot (Maranta arundinacea L.) had an important crop as a potential source of food and substitute for wheat flour and potential to be planted under Mindi trees (Melia azedarach L.) which had also potential as an alternative tree planting for the community forest. This research was aimed to 1) analyze the growth of Mindi trees and the productivity of arrowroot under mindi trees compared to monoculture system, 2) analyze the nutrient content of arrowroot under mindi trees compared to monoculture system. The experiment used a complete randomized design (CRD) with the agroforest under mindi trees and monoculture system as a factor. The result of growth in mindi showed that there is no significant difference in height, diameter, and canopy variable in agroforestry and monoculture plantation system while the root variable had significant difference among agroforestry and monoculture system. The physicochemical and nutrients content of arrowroot were diverse whereas there is no significant difference between the two system tested.Keywords: agroforestry, growth, productivity, fisikokimia, soil nutrient

Published: September 2021

Welder-dependent manufacturing is no longer suitable for the modern production of a high-performance nuclear pressure container. The high-quality root pass welding of medium-thick steel plates is the main challenge to obtain a sturdy reactor vessel, especially to generate one-sided welding with back-formation bead without a backing. Herein, low frequency and large duty-cycle pulsed gas tungsten arc welding (GTAW) was employed to weld the medium-thick steel plates with a 5-mm root face and 2-mm root opening. The arc characteristic and weld pool dynamic behavior in the proposed GTA root pass welding was investigated by a high-speed camera, and a deflection phenomenon of arc tail flame was first found. The correlations of the characteristic parameters of the arc tail flame, including the deflected angle and length, with the weld joint penetration and welding speed were also analyzed in detail. The results showed a negative correlation to the welding speed and a positive correlation with the weld joint penetration. A sound weld bead was formed at a range from 15 deg and 20 mm to 19 deg and 27mm. Based on the above relationship, a new method using these two characteristic parameters was proposed to identify the weld joint penetration in the root pass welding, and its fundamentals were completely demonstrated by the dynamic change of the keyhole. Its feasibility was also demonstrated by the experiment combined with the weld pool dynamic-dependent theoretical analysis.
Resistance of Austenitic Stainless Steels to Ductility-Dip Cracking: Mechanisms
Authors:   American Welding Society, YU PING , MORROW JUSTIN , KOU SINDO
Published: September 2021

In Ni-based alloys, precipitates that form along grain boundaries (GBs) during terminal solidification have been shown to pin GBs and resist GB sliding, which can cause ductility-dip cracking (DDC). As a result, it is often suggested that the stainless steel skeletal/lacy  in a  matrix resists DDC because it pins GBs. In the present study, austenitic stainless steels 304, 316, 310, and 321 were quenched with liquid Wood’s metal (75˚C) during welding. Quenching captured the elevated-temperature micro-structure and simultaneously induced cracking, thus revealing the mechanisms of the resistance to DDC. In addition, DDC was much higher in 310 than 304, 316, and 321, which is consistent with results of conventional tests. Both 304 and 316 solidified as columnar  grains, with continuous  formed along GBs soon after solidification to resist DDC along the GBs. 321 solidified as equiaxed grains of  instead of columnar, and the tortuous GBs associated with equiaxed grains resisted DDC. 310, however, solidified as coarse, straight  grains with little  along the GBs, and solidification GBs migrated to become locally straight. The resulting GBs were long, straight, and naked, which is ideal for DDC. In 304, 316, or 321, skeletal/lacy  in a  matrix did not exist in the fusion zone near the mushy zone, where DDC occurs. This proved skeletal/lacy  cannot resist DDC as often suggested. Instead, the present study identified two new mechanisms of resistance to DDC: 1) formation of continuous or nearly continuous  along boundaries of columnar  grains and 2) solidification as equiaxed  grains.

Background: SARS-CoV-2 causes respiratory tract infections that can sometimes become severe, and the virus was first identified in Wuhan city, China, in late 2019. The term COVID-19 is used for clinical diseases caused by SARS-CoV-2. The number of cases and literature related to the radiological picture of COVID-19-induced pneumonia, its findings, and contribution to diagnosis, correlation with RT-PCR, and its differences with adults is still limited to pediatric patients. Methods: We performed literature searches of the latest articles with PubMed, Google Scholar, and Cochrane Library databases published from 2016 to 2020 (5-year span). Two reviewers searched all articles independently (W and I., with more than five years of experience in radiology, respectively). Results: A total of 35 papers was identified and screened for eligibility from medical databases. There were 24 papers and included in this review. In the population of children, manifestations in radiology are less noticeable. The diagnosis of COVID-19 should prioritize the usage of CXR. Radiology in COVID-19-induced pneumonia may differ between the population of children and adults. Patchy lesions are the most commonly found images on chest x-rays, while bilateral ground-glass opacities (GGO) are the most often features in CT scans. Peribronchial distribution and peribronchial cuffing were more commonly seen in pediatric patients but less frequently found in adults. Conclusion: The characteristics of radiological features in pediatric patients with COVID-19 infection are patchy lesions, peribronchial distribution, and peribronchial cuffing.

Parents who have cancer face particular problems in their relationships with children. This study aims to clarify 1) the current status of challenge/hope in parental cancer, 2) the factors related to challenge/hope, and 3) the relationship between challenge/hope and QOL/stress-coping ability. Cross-sectional national survey was conducted at designated cancer hospitals in Japan. Participants were undergoing cancer treatment and have children under 18 years old. The questionnaire included demographic data, QOL, ability to cope with stress, and challenge/hope. From 11 hospitals, 54 patients (response rate: 79.4%) participated. Majority of participants were female (72.2%) with the mean age of 39.3 ± 5.3 (SD). The total score was QOL (FACT-G: 50.4 ± 16.2), stress-coping ability (SOC: 46.7 ± 10.4). The main challenges were an inability to fulfill the parental role and children’s mental suffering due to loneliness. The main aspects of hope were the value of the children’s present self, being a parent, and strengthening family bonds. Gender and disease duration were significantly related with challenge/hope. Challenge was significantly related with QOL/stress-coping ability. Parents who have cancer derive hope from their relationship with their children, although they feel a gap between their ideal role/value as a parent and their current status.

Toisinajattelijoiden julkisuuskuvat

Published: September 2021

Kirjailijoiden julkisuuskuvista ja kirjailijan imagon merkityksestä kirjamarkkinoilla puhutaan nykyisin paljon suomalaisessa mediassa. Myös aiheeseen liittyvä tutkimus on lisääntynyt 2000-luvun kuluessa. Uusia tulokulmia kirjallisuuden ja yhteiskunnallisten ilmiöiden suhteiden tarkasteluun on tuonut etenkin feministisen ja postkoloniaalisen tutkimuksen synty, mutta myös queer-teoria ja ekokritiikki (Braun & Spiers 2016, 449). Nämä tutkimusalat ovat paljastaneet muu muassa, miten kirjailijan sukupuoli, seksuaalisuus, ”rotu” tai etnisyys ovat vaikuttaneet siihen, miten heidän tuotantoaan on arvotettu. Kuuluisuuden tutkimuksessa keskeinen kysymys intiimiyden tasoja eri tavoin muokkaavista tekijöistä korostaa näkökulmaa, jossa kirjallisuuden tähtinimiä ei nähdä vain julkisuuden marionetteina vaan julkisuutta aktiivisesti erilaisiin tarkoitusperiin hyödyntävinä ja omien julkisuuskuviensa rakentamiseen osallistuvina (Moran 2000; Marshall 2010; Rojek 2016; Braun & Spiers 2016).

The number of zebrafish in biomedical research has increased exponentially over the past decades, leading to pressure on the laboratory animal community to develop and refine techniques to monitor zebrafish health so that suitable stocks can be maintained for research. The water filtration
assay is a promising technique in which water from a zebrafish system is filtered, and the filter analyzed by PCR. In the present report, we studied how the volume of water tested and the concentration of bacterial pathogens affected test results. To do so, we used stock solutions of 3 zebrafish
pathogens: Edwardsiella ictaluri, Aeromonas hydrophila, and Mycobacterium marinum. We used these stocks to create solutions with known concentrations of each pathogen, ranging between 102 and 107 Colony Forming Units (CFU) per ml. One, 2, and 3 L
of each solution was filtered using positive pressure, and the filters were submitted to a commercial lab for PCR testing. Results were fit with a logistic regression model, and the probability of obtaining a positive result were calculated. Test sensitivity varied by organism, but in general,
test results were positively correlated with the volume of the water filtered and with the concentration of bacteria in solution. We conclude that a positive result can be expected for E. ictaluri at 105 CFU per mL, A. hydrophila at 106 CFU per ml, and M.
marinum at 106 CFU per mL, when 3 L of solution are filtered.

The ongoing digital transformation is changing work processes and production environments. Particularly small and medium-sized enterprises (SMEs) in the European textile industry are confronted with numerous related challenges. Among these, demand-oriented development and efficient use of employee competences are becoming ever more important for success. New decentralized and situationally adaptable solutions that enable self-organized learning paths and informal competency development are becoming a necessity for the participants in production processes to acquire the essential competences. Approaches to support self-organized learning paths and dynamic, role- and actor-based models for collaborative knowledge generation already exist and have proven especially worthwhile in the SME environment of the textile industry and its innovation processes. This paper presents challenges of collaborative competence development and approaches to solve them on different levels of the organization. In addition, it explains specific implementations based on project examples from the textile industry and outlines needs for further research.
Analysis of supply-chains in the circular economy by means of VSM
Authors:   Manufacturing Engineering University of Luxembourg, Mangers Jeff , Plapper Peter
Published: September 2021

The Circular Economy (CE) concept aims to close resource loops and keep resources in the system for as long as possible at the highest utility level, without neglecting the goals of sustainable development. This paradigm shift from a finite and linear to a circular economy is however only possible if systems can be viewed as holistic overall systems. Thus, preventive problems can be identified and located as early as possible and counteracting measures initiated. This paper presents a new value stream mapping (VSM) model to consider interrelated processes in a holistic manner, regarding the requirements of CE. To do so, one macro-level to consider interrelated company relationships together with a respective micro-level to consider the individual company specific processes are elaborated. The degree of circularity is determined based on the 9R framework and new visualizations and measurement indicators are added at the different levels. This new model helps to mainly identify hurdles at a product's end-of-life, which are preventing a circular flow of resources, worth sharing with the responsible of a product's beginning-of-life. The model itself is validated by an extensive cross-company PET-bottle case study in Luxembourg.
