Analysis of the polymeric abrasive paste regeneration for abrasive flow machining
Authors: Nowacka Agnieszka , Klepka Tomasz
Published: September 2021

The influence of conditions and the sifting process efficiency of the worn-out polymeric abrasive paste containing silica (SiO2) and polymer chips remaining after the surface treatment were investigated. The abrasive paste regeneration process consisted of sifting the used paste through sievesof a vibrating screen, on which abrasive grains and polymer chips were recovered. The diameter of the sieve holes determined the size of the recovered abrasive grains and polymer chips, on the size of which the efficiency of the process depended. The lowest efficiency of the sifting process was obtained using a sieve with the holes diameter equal to the diameter of the grain and the polymer chips of thegiven fraction. The highest efficiency of the sifting process was obtained for a sieve with a diameter of 0.032 mm. The regenerated polymeric abrasive paste can be reused in the process of abrasive flow machining.
Effect of Tool Rotational Speed and Traverse Speed on Friction Stir Welding of 3D-Printed Polylactic Acid Material
Authors: Senthil S. M. , Kumar Manickam Bhuvanesh
Published: September 2021

Joining of polymers are usually carried out using adhesives that has a deteriorating quality at elevated working conditions thus limiting its application areas. Friction stir welding (FSW) is a growing solid-state welding technology, with applications including the welding of lightweight materials. FSW was recently introduced for joining thermoplastics materials and found successful. This study attempts in employing FSW to join polylactic acid (PLA)-based 3D printed engineering components and assess the effect of FSW process parameters (tool rotational speed and traverse speed) on the weld property. The present work uses the FSW process to butt weld 5 mm thick 3D printed PLA sheets with taper cylindrical profiled tool. For the experimentation, three different combinations of feed rates and pin rotational speeds are considered. Based on joint efficiency evaluation, it is found that tool rotational speed of 1400 rpm combined with 10 mm/min transverse speed produces the weld with high joint efficiency of 40%.
Properties of Mortars Mixed with Polystyrene and Hemp Fiber Wastes
Authors: Suwansaard Apised
Published: September 2021

When polystyrene (PS) and hemp fiber waste were mixed into the sand aggregate, some physical-mechanical properties of mortar changed. The PS and hemp fiber were tested as partial replacements for sand in mortar with three designated percentages of 2.5, 5.0 and 10.0% by mass. The properties of mortar with PS were found to be better than that of the mortar with hemp fiber. The water absorption of mortar with PS was comparable with the reference mortar but lower than that of mortar with hemp fiber. The compressive strength of the mortar with PS was higher than that with hemp fiber whereas the tensile strength of the mortar with 2.5% PS and hemp fiber was comparable and was higher than that of the reference mortar. The thermal conductivity of a wall plastered by mortar containing PS decreased as the PS content was increased, whereas the thermal conductivity of a wall plastered by mortar containing hemp fiber increased as the hemp fiber content was increased. Thick crack was detected in the reference wall while hair line crack occurred from the wall plastered with PS and hemp fiber mortars. The results indicated that 10.0% PS could be used as a partial replacement for sand in mortar with an improvement in some of the properties of the mortar.

Authors: Isaac Ocheng V. O. Isaac , Ika Eddy , Omona [PhD] Kizito
Published: September 2021

Background: In Uganda, 25 % of adolescents age 15-19 have already begun childbearing, 19 % have already given birth and another 5 % pregnant with their first child. Utilization of maternal health services is, therefore, an effective approach to reducing the risk of maternal morbidity and mortality. Low utilization of Maternal Health Services (MHS) has been registered in many parts of Uganda.Objective: To identify the key factors that influenced the utilization of MHS by adolescent young mothers aged 15-19years in Kiryandongo general HospitalMethods: A Cross Sectional analytical design, both quantitative and qualitative was used. A total of 98 adolescent young mothers were randomly selected. Data was collected using semi-structure questionnaires and analyzed using SPSS version 19.Results: Level of utilization of MHS was 44.9%. The socio-demographic (personal) factors that significantly influenced MHS utilization were; maternal age (COR= 0.29; 95% CI: 0.13-0.67, p = 0.003), husbandâ€™s education level (COR= 0.19; 95% CI: 0.08-0.47, p =0.000) and husbandâ€™s monthly income (COR= 0.35; 95% CI: 0.15-0.80, p = 0.012). Health System factors that influenced MHS utilization included; Time for travelling to reach health facility (COR=2.39; 95% CI: 1.03-5.52, p = 0.040) and Cost of the health services (COR= 2.68; 95% CI: 1.17-6.15, p =0.019).Conclusion: Strategies in addressing decision-making norms, engaging in massive community dialogue and designing appropriate communication strategies may help improve MHS utilization.Â Â Â

Published: September 2021

Abdominal cocoon syndrome (ACS) is a rare cause of small bowel obstruction characterized by partial or complete encasement of small bowel loops in a thick fibro-collagenous sac. It poses diagnostic difficulties due to the non-specific nature of its presentation and thus in most cases, diagnosed incidentally at laparotomy.The researchers present a case of a 27-year old female Ugandan who presented to a rural hospital in Northern Uganda with complaints of central abdominal pain, failure to pass stool and bilious vomiting for three days. She also had feelings of a peri-umbilical mass. She had several episodes of related obstructive symptoms that would be self-limiting for a year. She had unremarkable past surgical, past medical and past gynecological history. Laboratory investigations were unremarkable.Preoperative diagnosis of small bowel intussusception was made basing on examination and ultrasonography report and the patient was managed operatively. At laparotomy, almost all the small bowel loops were found encased in a thick, whitish, fibrous membrane. There was also marked inter-loop adhesions. The membranous sac was incised and completely removed using both sharp and blunt dissection. Inter-loop adhesions were released solely by blunt dissection.The patient recovered postoperatively and was discharged on the seventh postoperative day.Â Â

Patient autonomy is one of the most important ethical values in the health care practice. Patientsâ€™ autonomy means the right of patients to make decisions about their medical care without their health care provider trying to influence the decision. Patientsâ€™ autonomy allows health care providers to educate the patients but do not allow them to make the decision for the patients.Â Â

Published: September 2021

Background. Acute or chronic rectal fistulas make up to 30% of proctologic pathology and are accompanied by significant impairment of patients` lives. In recent years, the role of matrix metalloproteinases in the pathogenesis of many diseases has grown rapidly. The most widely expressed protease in inflamed tissues is matrix metalloproteinase-9 (MMP-9).Objectives. To identify and analyze changes in the level of MMP-9 in the serum of patients with extrasphincteric fistulas of the rectum, depending on the method of surgery.Methods. The study involved 28 patients with extrasphincteric rectal fistulas, who undergone surgery in the proctology department of Poltava Regional Clinical Hospital and the surgical department of the 3rd city clinical hospital in Poltava from 2010 to 2018. The patients were divided into 2 groups according to the method of surgical treatment. Quantitative determination of MMP-9 in blood serum was performed.Results. In the main group, the average value of MMP-9 before surgery was 14.90 Â± 0.15 ng/ml, a month later it decreased to 7.73 Â± 0.37 ng/ml (pË‚0.0001), and after three months, the average value of MMP-9 was determined at 2.41 Â± 0.13 ng/ml (pË‚0.0001). In the comparison group, the initial average value was 15.00 Â± 0.08 ng/ml, which decreased to 11.89 Â± 0.26 ng/ml (pË‚0.0001), and three months after surgery it decreased to 4.14 Â± 0.17 ng/ml (pË‚0.0001).Conclusion. The use of MMP-9 levels in blood serum before and after surgery has determined that the method of treatment of extrasphincteric fistulas using the drug Tachocomb is less traumatic and reduces the healing time of postoperative wounds compared to the ligature method.Â Â Â

A satisfação com a escola e o desempenho escolar do estudante são aspectos fundamentais a serem gerenciados pelas instituições de ensino, no entanto, pouco se avalia como se dá essa relação. Verificamos de que modo a satisfação de estudantes com o ensino profissional integrado ao ensino médio da rede Estadual de ensino do Recife, Brasil se relaciona com o desempenho escolar a partir do Índice de Desenvolvimento da Educação de Pernambuco (IDEPE). A pesquisa é do tipo exploratória-descritiva, sendo realizada por meio de um survey presencial. Coletamos dados de duas unidades escolares e, em seguida, comparamos com o índice analisado. Os resultados indicaram que os estudantes da escola com desempenho melhor no índice, são mais satisfeitos. Os serviços prestados também foram mais bem avaliados pelos participantes da escola com maior desempenho, indicando que a satisfação pode influenciar positivamente o resultado do índice. Este estudo contribui de forma teórica e prática ao revelar que apesar da estrutura ser um aspecto relevante para avaliação dos estudantes, o que mais aumenta a satisfação e o desempenho nos índices escolares é a maneira na qual os serviços são oferecidos pelas instituições.
Particularidades del diseño
Authors: Forero-La-Rotta Augusto , Ángel-Peña John Anderson
Published: September 2021

En este capítulo se aborda la evaluación del impacto de la revolución tecnológica en los procesos de diseño, especialmente aquellos inducidos por la velocidad y disponibilidad de información, que no son todavía claros pero que se manifiestan en la tendencia hacia un proceso de diseño más integrado, que parece interesarse cada vez más en el usuario y sus experiencias, y en la construcción de significados reconocibles en la interacción entre el objeto y la realidad social a sus diversos niveles de acción, donde la identidad se afirma en la coherencia con un patrón de atributos reconocibles. Manejar problemas cada vez más complejos y a veces caóticos requiere el acercamiento a la comprensión de las variables en conflicto de una manera holística. En comparación con el diseño tradicional, el reconocimiento previo de las experiencias deseadas podría determinar un nivel más alto de aceptación y una correlación más significativa con los objetos por parte de los usuarios, lo que puede influir notablemente en los procesos de toma de decisiones de diseño. El pensamiento integrativo orienta la generación de estrategias y mecanismos destinados a coordinar la información compartida y las asociaciones entre los significados perceptivos y simbólicos del producto.

Published: September 2021

Research has shown that stress experiences begin in early stages of life. Stress management techniques have appeared to be beneficial for the development or enhancement of stress coping skills. The aim of this pilot randomised controlled trial was to assess the effect of a 12-week intervention, comprising training in diaphragmatic breathing and progressive muscular relaxation, on elementary school students’ stress levels. Outcomes on the quality of life and behavioural aspects of the students were also assessed. Standardised questionnaires were administered at baseline and after the 12-week intervention program. Fifty-two children aged 10 to 11 years were randomly assigned to intervention (n=24) and control groups (n=28). Children of the intervention group demonstrated lower levels of stress (in all three subscales of lack of well-being, distress, and lack of social support) and improved aspects of quality of life (physical, emotional, and school functioning). No significant differences were observed regarding the examined behavioural dimensions, in the intervention group. Larger randomised controlled trials with follow-up evaluations are needed to ascertain the positive outcomes of such programs on elementary school children.
Switchable electromagnetic shield based on seawater
Authors: Wang Shen-Yun , Sheng Ke-Feng , Li Bing-Xiang
Published: September 2021

In this paper, we propose a concept of switchable electromagnetic shield based on seawater. The shield is designed to be a multilayer structure consisting of one chamber layer filled with free space or seawater and three dielectric layers to match with the communication wave signal. At low-power signal for communication purpose, the shield with the chamber layer filled with free space can make the wave signal transparently propagate through. At high-power interference microwave signal impinging onto the shield, the structure with the chamber layer filled with seawater can reflect and absorb the microwave energy. Transparency state for communication signal is designed based on the theory of transmission line, where a key indicator for communication signal transmission is the input impedance of the shield. Shielding state is theoretically calculated under different seawater parameters in a wide frequency band. Both the transparency and shielding states are validated by full-wave numerical calculations, and the results are in good agreement.

Heating under pressure treatment (HUP) is a method which can keep the complete form of quinoa grain after processing, which is beneficial to the development of subsequent products. The conditions for quinoa heating under pressure was optimized by response surface methodology to be: quinoa grains were regulated with adding 6.3% of pH 7.0 water and heated under 0.36 MPa pressure for 3–5 min, resulting in the predicted maxima of total phenolic content (TPC), Flavonoid and Saponin content were 313.21 mg GAE/100 g, 1.621 mg/g, and 16.78 mg/g and the values of OH Scavenging Rate, DPPH Scavenging Rate, ABST+ Scavenging Rate were 69.45, 91.73, and 52.38% separately. The content of flavonoid and saponin in the HUP samples were more than that in the boiled, baked, and extruded samples, which were close to that in raw quinoa sample, and meaning high retention of active phytochemicals and antioxidation activity in HUP quinoa. The hydroxyl radical scavenging rate is related to the content of polyphenol, flavonoid and saponin.

Published: September 2021

In this article, the laser-assisted ultrasonic vibration dressing technique was applied to the cubic boron nitride (CBN) grinding wheel to study the effect of various process parameters (namely, laser power, dressing depth, feed rate, and grinding wheel speed) on the grinding force, surface quality, and morphological evolution of CBN abrasive particles. The results showed that abrasive particles’ morphology mainly undergoes micro-crushing, local crushing, large-area crushing, macro-crushing, and other morphological changes. The dressing force can be effectively reduced by controlling the dressing process parameters. Besides, grinding tests are performed on the grinding wheel after dressing to reveal specimens’ surface quality. Excellent grinding characteristics and grinding quality of the grinding wheel were obtained by the proposed technique with the optimized process parameters.
Die „Opponenten“ des Paulus im (heilsgeschichtlich profilierten) Galaterbrief
Authors: Bachmann Michael
Published: September 2021

Man hat es beim polemischen Galaterbrief indirekt auch mit „Opponenten“ des Paulus zu tun. Die Passagen 1,6–9; 3,1f.5; 4,17; 5,7–12; 6,12–14 offerieren Indizien und „Schattierungen“ (z. B.: keine „Beschneidung“ [von Heidenchristen] versus Beschneidungsforderung; „aus der Glaubensbotschaft“ versus „aus Werken des Gesetzes“). Hinsichtlich der unterschiedlichen „Opponenten“-Hypothesen ergibt sich so: wahrscheinlich „judaisierende Judenchristen“! Weitere Galaterbrief-Aussagen kommen hinzu: zu den „Werken des Gesetzes“ (s. 3,10), bei denen es sich um Tora-Vorschriften handeln wird; zum „Gesetz“ (s. 3,23; 5,13f.), das der Adressant positiv gewertet wissen will; zur Gefahr der Restituierung (s. 2,18; 4,9b; 5,1) des früheren heidnischen Lebens; zu Heilsgeschichtlichem (s. 6,16: „Israel Gottes“, doch wohl auf Juden zu beziehen); zu Jerusalem (s. 1,17f.; 4,25f.). Insofern stehen sich offenkundig zwei unterschiedliche judenchristliche Positionen gegenüber.

Published: September 2021

Women are ubiquitously exposed to non-persistent endocrine disrupting chemicals (EDCs) from food contact materials and personal care products. Understanding the impacts of exposure to these chemicals on pregnancy and long-term health outcomes in women is a critical area of research that has been largely overlooked. This brief review focuses on the epidemiologic literature exploring associations of non-persistent EDCs – including phthalates, parabens, bisphenols, and triclosan – with maternal pregnancy outcomes and long-term health outcomes in women. We focus on the challenges of this research, particularly assessing non-persistent EDC exposures, aspects of study design, and statistical approaches. We conclude by reviewing the best practices for non-persistent EDC research with regards to pregnancy and women’s health. Though limited, we found some evidence indicating that exposure to non-persistent EDCs is associated with pregnancy health. However, findings from these studies have been inconsistent and require corroboration. Recent studies have also proposed that non-persistent EDC exposures in pregnancy may adversely affect postnatal maternal health. To date, only a few studies have been conducted and have only focused on postpartum weight. More research is needed in this area to inform efforts to promote optimal health across the lifespan of women.

Published: September 2021

Sungkai (Peronema canescens Jack) is an alternative natural ingredient that can be used as an antidiabetic containing several secondary metabolites which are thought to reduce blood glucose levels by inhibiting the action of the α-glucokinase enzyme and increasing the activity of antioxidant enzymes and being able to regenerate β-cells, damaged pancreas so that insulin deficiency can be overcome. The aim of this study was to determine the effect of P. canescens leaves ethanol extract on antidiabetic activity and to determine the effect of various doses of sungkai leaf ethanol extract as antidiabetic. The scientific research method used in this study was a completely randomized design (CRD) and data analysis used in this study is the one way ANOVA, following by the Duncan test. Blood glucose measurement in treated mice was carried out 3 times. Mice were devided into five groups, three mice in each group, and each group was administered different dosages of sungkai extract (T1 = extract 175 mg/kg body weight; T2 = extract 350 mg/kg body weight; T3 = extract 700 mg/ kg body weight). First, the mice were acclimatized for six days and the injection of treatment was started at day 7. Blood glucose levels, urine volume, body weight and daily drinking of mice was carried out before induction (day 0), after induction (day 8) and after the end of treatment for 10 days (day 18), was carried out using the Point of Care Test (POCT) method using the Easy Touch GCU. The results showed that the ethanol extract of sungkai leaves had the potential to reduce blood glucose levels in mice. The ethanol extract of sungkai leaves at a dose of 350 mg/kg body weight has the most optimal potential to reduce blood glucose levels, urine volume, daily drinking, and body weight.
Timing of Intervention in Asymptomatic Patients with Aortic Stenosis
Authors: Sevilla Teresa , Revilla-Orodea Ana , San Román J Alberto
Published: September 2021

Aortic stenosis is a very common disease. Current guidelines recommend intervention mainly in symptomatic patients; aortic valve replacement can be considered in asymptomatic patients under specific conditions, but the evidence supporting these indications is poor. Continuous advances in both surgical and percutaneous techniques have substantially decreased rates of perioperative complications and mortality; with this in mind, many authors suggest that earlier intervention in patients with severe aortic stenosis, when they are still asymptomatic, may be indicated. This paper summarises what is known about the natural history of severe aortic stenosis and the scientific evidence available about the optimal timing for aortic valve replacement.

Published: September 2021

El problema de la disponibilidad de agua y su importante papel en el sector agrícola, específicamente en la presión que existe actualmente por el recurso hídrico, pero además en países como Colombia donde el cultivo del café tiene una importancia histórica, cultural y económica, lo que hace necesario un estudio de la huella hídrica de este cultivo en el país. Aquí se presentan los resultados de la huella hídrica de la producción de café (cultivo y beneficio) en Colombia, por el método de beneficio tradicional y ecológico. Para su cálculo se siguió la metodología propuesta por Water Footprint Network. La huella hídrica verde promedio del cultivo de café en Colombia es de 8.746 m3 t-1, no tiene huella hídrica azul porque no requiere riego y la huella hídrica gris es del orden de 7.000 m3 t-1. El beneficio tradicional de café no tiene huella hídrica verde, la huella hídrica azul es de 4.00 m3 t-1 y tiene una huella hídrica gris de 3.200 m3 t-1. El beneficio ecológico Becolsub® tiene una huella hídrica de azul de 0,60 m3 t-1 y una huella hídrica gris de 1.739 m3 t-1; mientras la tecnología Ecomill® sin vertimientos de aguas residuales tiene una huella hídrica azul de 0,55 m3 t-1 y no tiene huella hídrica gris porque no presenta vertimientos. Esto implica que el método de procesamiento ecológico Becolsub® Esto implica que el método de procesamiento ecológico Becolsub® disminuye la huellahídrica en un 45,7% y en un 99,9% con el proceso ecológico Ecomill® (sin descarga de aguas residuales) en comparación con la tecnología tradicional de procesamiento húmedo. A nivel mundial, Vietnam cuenta con la menor huella hídrica, seguido por Colombia, Etiopia, Brasil, Perú e Indonesia. La huella hídrica del café, depende del clima y el rendimiento del cultivo, por esta razón, la huella hídrica del cultivo de café varia significativamente con el lugar y el periodo de evaluación.
Comparison of statistical indices for the evaluation of crop models performance
Authors: Saldaña Villota Tatiana María , Cotes Torres José Miguel
Published: September 2021

This study presents a comparison of the usual statistical methods used for crop model assessment. A case study was conducted using a data set from observations of the total dry weight in diploid potato crop, and six simulated data sets derived from the observationsaimed to predict the measured data. Statistical indices such as the coefficient of determination, the root mean squared error, the relative root mean squared error, mean error, index of agreement, modified index of agreement, revised index of agreement, modeling efficiency, and revised modeling efficiency were compared. The results showed that the coefficient of determination is not a useful statistical index for model evaluation. The root mean squared error together with the relative root mean squared error offer an excellent notion of how deviated the simulations are in the same unit of the variable and percentage terms, and they leave no doubt when evaluating the quality of the simulations of a model.
Phraseologismen im Bereich der Sexualität. Eine lexikographische Analyse an deutschen und polnischen Beispielen
Authors: Lidzba Aleksandra , Suchorab Krystian
Published: September 2021

People’s sex life is very often, if not always, taboo in everyday life. The theming of this area of life is made possible by various linguistic means that allow one to speak about this content. Phraseological units also serve this purpose. The starting point of this article is the definition of phrasemes according to Burger (2015:11): “Firstly, they [phraseologisms] consist of more than one word; secondly, the words are not put together for this one occasion, but are combinations of words that we, as German speakers, know exactly in this combination (possibly with variants), similar to how we know German words as individual items”. In addition, it is noteworthy that thanks to the characteristic of idiomaticity (cf. Fleischer 1982:30), this taboo is particularly reinforced. At the center of our analysis are phrasemes related to sex life. The research material was taken from German and Polish dictionaries. The purpose of the presentation is to create a typology of thematic areas which are characterized with the help of phrasemes relating to sex life in German and Polish. The article is based on the following definition of a taboo: “an unwritten law that forbids doing certain things based on certain beliefs within a society” (Duden 2015:1735).

Published: September 2021

In the first part, the study presents a brief characteristics of the development of the Modern High German language after 1650 from the point of view how other languages influenced its vocabulary and analyses numerous loan words. The second part deals with the origins and the first activities of the General German Language Society (from 1885 on) which became the leader in the field of the institutionalised ideological fight against foreign words in the central German language area. The third part introduces the research results of the affiliate societies which were founded in Moravia, one of the part of the Lands of the Bohemian Crown. Both the information in the journal of the General German Language Society and archive documents in three Moravian archives (in Brno, Jihlava and Nový Jičín – the only Moravian cities where affiliate societies were founded) show that their existence was rather a peripheral issue in these cities. As opposed to this, affiliated societies were very active in the cities of northern Bohemia. At the end of the study, the author considers the reasons which caused this kind of situation in Moravia.

Published: September 2021

Sauvignon Blanc represents an important grape variety. The wine made from this variety is known to have a wide range of aroma profiles from nettles to tropical fruits. Beside the raw material quality (grapes), the quality of wines can be fundamentally influenced by the technological conditions applied in the wine making process. Yeast and other microorganisms play a key role in the formation of metabolites during alcoholic fermentation. In this study, the effects of autochthonous or selected wine yeasts (Saccharomyces cerevisiae) and fermentation temperatures (15 °C and 19 °C) were tested on major monoterpenes contents of wines during the period 2016–2017. The obtained values show that the highest contents of linalool (24.36 μg L−1) and hotrienol (11.84 μg L−1) were determined in wine samples produced with active (selected) wine yeast at lower temperature. Sensory evaluation results indicated that monoterpenes can have a positive effect on the overall sensory quality of Sauvignon Blanc wines, despite the fact that their determined concentrations in the evaluated samples were not higher than their threshold values.

Published: September 2021

Background and aims

The prevalence of internet addiction (IA) varies widely in the Gulf Cooperation Council (GCC) countries (4%–82.6%). We aimed to assess the quality of IA studies from the GCC and pool their data to get an accurate estimate of the problem of IA in the region.

Methods

A systematic review of available studies was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PubMed, Embase, and Cochrane Controlled Register of Trials were systematically searched; studies conducted in GCC countries (i.e., Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) with a validated instrument for internet addiction assessment were eligible. Ten studies were eligible for the systematic review, all of which were included in the meta-analysis. The Newcastle Ottawa Scale was used for quality assessment.

Results

Nine out of ten of the included studies had either adolescent and/or young adult participants (age < 25). Two studies were of ‘good’ quality, six were of ‘satisfactory’ quality, and two were of ‘unsatisfactory’ quality. The pooled internet addiction prevalence was 33%; it was significantly higher among females than males (male = 24%, female = 48%,P= 0.05) and has significantly increased over time (P< 0.05).

Discussion and conclusions

One in every three individuals in GCC countries was deemed to be addicted to the internet, according to Young's Internet Addiction Test. A root cause analysis focusing on family structure, environment, and religious practices is needed to identify modifiable risk factors.
Factors influencing the willingness of Hungarian sour cherry growers to operate in a short supply chain
Authors: Ványi Noémi , Felföldi János
Published: September 2021

Although a number of studies have been conducted over the past decade to understand the factors influencing the willingness of producers to operate in a short supply chain (SSC), the intention to adapt can still be identified as an unexplored area. The main aim of the present study is to determine the extent to which Hungarian fresh sour cherry producers show a willingness to operate in a short supply chain and what investments they would make to do so. The sour cherry producers involved in the study clearly show a willingness to operate in a short supply chain. Some producers approach this in a “complex” manner, so they would even meet individual consumer needs and deliver orders to the consumer. Farmers opting for a “simpler” solution would prefer to sell their products to the consumer at their premises or at farmer’s markets. Further results support the fact that the more producers believe in the viability and future of SSCs and the higher their level of education is, the more willing they are to adapt in terms of resources or production processes in order to achieve complete transition. The results reflect the importance of examining the factors that determine farmers’ intentions to operate in the short supply chain, but it is also worthwhile and justified to explore how willing they are to “sacrifice” and invest in order to completely adapt.

The research objective was to analyze the phenomenon of floods and landslides in the perspective of perennial philosophy. The method used in this research is a type of qualitative research through literature study. The results of this study indicate that in the perspective of perennial philosophy, various disaster phenomena such as floods and landslides are caused by human behavior that has been arbitrary towards nature. Especially, with the development of modern science and technology that has encouraged humans to exploit massively natural resources, thus losing the balance in nature. Excessive exploitation of nature causes nature to be damaged and in the end there are terrible disasters. The conclusion from the research is that various natural disasters such as floods and landslides that occur in the midst of Indonesian human life can be viewed from the perspective of perennial philosophy. This research recommends the importance of preserving nature. Besides that, the importance of reviewing and dismantling modern science has killed perennial metaphysics which shows the essence of divine reality in life and mind.

Psikoterapi Abū Naṣr al-Sarrāj al-Ṭūsī: Tinjauan atas al-Maqāmāt al-Rūḥāniyyah dalam Kitab al- Luma‘
Authors: Haqq Muhammad Valiyyul
Published: September 2021

Appeared for the first time in 1965 in the monumental work of Reza Arasteh, Sufi spiritual approaches and methods in psychotherapy have to wait for Muslim scholars attention in the 21st century. To our concern, up to now only few studies which dive in the ocean of Sufi doctrinal aspects of psychotherapy: most of them still swim at the upper level trying to estimate the possible relationship between Sufi spiritual practices and methods of psychotherapy. However, to our surprise, none of these few studies that focus on the Sufi spiritual maqāmāt, the well-known meticulous step-by-step guidance for those who want to master their soul and mental states. In the absence of this, the present article attempts to explore the maqāmāt discussed by Abū al-Naṣr al-Sarrāj al-Ṭūsī in his famous al-Luma‘ in light of psychotherapy. At the end this article finds that these Sufi maqāmāt are not only means for spiritual purification, i.e., soul and mental well-being, but also al-Sarrāj’s model of Sufistic psychotherapeutic outline method.

Wara’ dalam Ajaran Tasawuf Imam Junaid Al-Baghdadi
Authors: Asy'ari Abdul Hasib
Published: September 2021

The peak of Imam Junaid's Sufism is monotheism. One of the efforts to achieve this is the attitude of wara' by always emphasizing on self-awareness so as not to neglect the purpose of the search. This study uses a qualitative approach with data sources obtained from books, books and journals that examine wara', especially the views of Imam Junaid al-Baghdadi which aims to determineanalyze the teachings of al-Junaid aboutwara' in all aspects of life in order to avoid behaviors that can distance themselves from Allah Swt. This is needed because every individual Muslim should continue to protect himself from bad things and not fall into it. The results showed that wara'in the view of Al-Junaid has a close correlation with the intensity of one's awareness in controlling one's behavior in order to avoid things that can distance oneself from Allah Swt. It develops as far as the knowledge possessed, so that the more mature the knowledge and the intense in applying it, the higher the degree of one's sanity. So it can be concluded that wara' is based on awareness and knowledge to be aware of the behavior of the limbs from temptations that come from outside themselves.
Definición de religión y organización con fines religiosos en el ordenamiento jurídico estadounidense
Authors: Celador-Angón Óscar
Published: September 2021

El objeto de esta investigación es analizar la definición de religión y de organización con fines religiosos en el ordenamiento jurídico estadounidense, así como la relación que existe entre dicha definición –o ausencia de la misma– y los principios que ordenan su modelo constitucional. Para ello, hemos estudiado las decisiones del Tribunal Supremo federal, en aquellos contextos en los que este se ha visto obligado a determinar quiénes son los sujetos pasivos del derecho de libertad religiosa, y en concreto en el terreno de la práctica de la oración en la escuela pública, la objeción de conciencia al servicio militar, la asistencia religiosa en prisiones, y el régimen fiscal de las organizaciones con fines religiosos.
El papel de los legados pontificios en la promoción de la paz
Authors: Ujházi Lóránd
Published: September 2021

La personalidad jurídica internacional de la Santa Sede proporciona oportunidades excepcionales en la construcción de la paz. Mediante los legados papales, la Iglesia Católica participa de una manera única en la vida de la comunidad internacional y por ende en la promoción de la seguridad y en la evaluación ética de las cuestiones relacionadas con la guerra. El artículo tiene como objetivo analizar los aspectos teóricos y prácticos del papel de los legados pontificios en la construcción de la paz. La hipótesis es que la participación de los legados pontificios en la gestión de crisis solo puede entenderse plenamente mediante la reflexión teológica. Además, apoyar la paz no es solo una de las muchas tareas de los legados pontificios, sino la más esencial. Por lo tanto, las misiones de apoyo a la paz representan una herramienta poderosa de cohesión entre los deberes ad intra y ad extra de los legados, ya sea para con una Iglesia particular, país anfitrión u organismo internacional.
Перспективність використання голозерного вівса в дієтичних продуктах без глютену. Експериментальне дослідження зміни структури зерна в процесі екструзійної обробки

Проведено аналіз світового і вітчизняного ринку виробництва безглютенових продуктів та встановлено перспективність цього напрямку через щорічне зростання кількості населення, яке нездатне засвоювати білок глютену. В Україні  власне виробництво безглютенових продуктів ще досить обмежене і основний асортимент продукції представлений імпортними виробниками. В рамках цього було окреслено основні проблеми та сформульовано завдання, які полягають у необхідності нарощування обсягів власного виробництва за рахунок пошуку нових видів сировини, оновлення рецептур та розроблення новітніх технологій обробки. Для вирішення цих завдань було проаналізовано різні види сировини з яких запропоновано використовувати голозерний овес як основу складу сухих дієтичних безглютенових сумішей. Для його обробки було запропоновано використовувати екструдер, оскільки він дозволяє за рахунок регулювання початкової вологи в зерні змінювати тиск, температуру процесу та час обробки, забезпечуючи при цьому необхідну мікроструктуру екструдату і високі якісні показники. Крім цього, під час екструзії відбувається знешкодження шкідливої мікрофлори і видалення надлишкової вологи, що дозволить збільшити термін зберігання сухої суміші і покращити якість змішування компонентів. Експериментальна частина досліджень полягала у визначенні доцільності використання екструдера для обробки голозерного вівса при отриманні сухих сумішей. Для цього експериментальним шляхом було встановлено механізм впливу екструзії на мікроструктуру зерна при різних режимах обробки та проведено порівняння екструдату зі зразками не обробленого зерна, а також проаналізовано динаміку структурних перетворень, які відбуваються в каналі екструдера. Проведено оцінку кількості залишкової вологи в отриманому екструдаті для визначення терміну зберігання сухих сумішей та параметрів змішування з іншими компонентами. Доведено доцільність використання в подальшому екструдера для обробки голозерного вівса при отриманні сухих сумішей.
