End-of-Life Management of Photovoltaic Panels in Austria: Current Situation and Outlook
Authors: Dobra Tudor , Wellacher Martin , Pomberger Roland
Published: March 2020

In recent years the end-of-life (EOL) management of photovoltaic (PV) panels has started to attract more attention. By including PV panels in the WEEE Directive in 2012 the European Union has introduced a concrete legislative framework regarding EOL for this sector. Several research investigations into specialized PV recycling processes have been conducted over the last years, although very few of the findings have been implemented on a commercial level up to now. Nowadays, recycling usually still takes place in general recycling plants for flat glass or waste electronics. In this work, the current situation regarding EOL management of PV panels in Austria is analysed by literature research and interviews with stakeholders relevant to the EOL of PV panels. The legislative framework (including national peculiarities) and its influence on current procedures regarding collection and subsequent treatment is shown. Furthermore, current recycling processes are described and a country specific prognosis model is created to assess the future development of waste quantities. Results show that the amount of PV panel waste arising in Austria at the moment is very small and therefore no dedicated recycling takes place. However, quantities will considerably rise in the upcoming years and will act as the main driving force for the implementation of an improved EOL management system including specialised recovery processes.
Utilization of demolition wood and mineral wool wastes in wood-plastic composites
Authors: Jetsu Petri , Vilkki Markku , Tiihonen Ismo
Published: March 2020

Wood and mineral wool fractions from demolished buildings were sorted into different categories and processed to the suitable grain size needed for the manufacturing of wood-plastic composites. Processed construction and demolition waste materials mixed with plastics and additives were extruded into hollow test bars using a conical rotary extruder. Test specimens needed for measurements were cut from test bars. The results showed that the mechanical performance of wood-plastic composites based on construction and demolition waste wood, and mineral wool was at a good level and comparable to commonly used wood-plastic composites in decking applications. The highest strength properties of wood-plastic composites were achieved with a plywood fraction and the lowest with materials containing a particle/fibre board fraction. The mechanical performance can be improved by utilizing mineral wool in the formulation of wood-plastic composites. A material mixture containing several wood fractions as well as mineral wool also gave good strength properties. Only a minor reduction in strength properties was measured when recycled plastic was utilized meaning that wood-plastic composites suitable for many types of applications can be produced entirely from recycled materials.

Design and predicting performance of carbon nanotube reinforced cementitious materials : mechanical properties and dispersion characteristics.
Authors: Ramezani Mahyar
Published: March 2020

Recently, Carbon Nanotubes (CNTs) are drawing considerable attention of researchers for reinforcing cementitious materials due to their excellent mechanical properties and high aspect ratio (length-to-diameter ratio). However, CNTs might not disperse well within the cement matrix, resulting in little improvement or even degradation of concrete properties. The uncertainty in producing the consistent results in different studies might be attributed to multiple interactions between the experimental variables affecting the nanotube dispersion and the final properties of CNT-cement nanocomposites. Therefore, this research mainly focused on proposing equations that can reliably capture these interactions in order to correlate CNT dispersion with the mechanical properties. The main experimental variables studied included CNT concentration, aspect ratio, ultrasonication energy, ultrasonication amplitude, surfactant-to-CNTs ratio, water-to-cement ratio, sand-to-cement ratio, and hydration age of specimen. The study reported in this research was conducted in two parts: experimental program and modeling. In the experimental part of this research, a total of 63 different mix proportions were used to evaluate the flowability, mechanical properties, and durability characteristics of cement pastes and mortars containing CNTs. Using experimental test results reported in this study and the literature, three critical relations were proposed to consider the CNT dispersion, cement matrix composition, and hydration age of cement. The proposed critical relations were then added to available theoretical models in the literature. The flexural strength and elastic modulus of CNT-cement nanocomposites were predicted through a state-of-the-art probabilistic model using a Bayesian methodology. Finally, the developed probabilistic models were used to identify the optimum ranges of the experimental variables to maximize the mechanical properties. This was done through computing the conditional probability of not meeting the specified design requirement. The experimental results indicated that addition of CNTs could significantly improve different properties of cementitious materials, if the optimum range of each variable was used. Also, to achieve the desired mechanical properties, various combinations of the experimental variables might be used. The proposed prediction models were shown to capture the interactions between the experimental variables for predicting the mechanical properties within ±15% and ±18% of the experimental test results for flexural strength and elastic modulus, respectively. Based on the findings of this research, contour plots were developed to provide practical guidelines for future engineers to design CNT-cement nanocomposites.

Published: March 2020

Objective: Virtual Reality (VR), a novel and highly immersive technology, offers promise in addressing potential psychological impacts of cancer treatments and hospitalization. The primary aim of this study was to examine multiple key user perspectives on the acceptability and feasibility of an Immersive VR therapeutic intervention for use with hospitalized oncology patients. Secondary aims were to identify issues and opportunities related to the adoption and clinical implementation of VR in pediatric oncology settings. Methods: The study was conducted at the Royal Children’s Hospital, Melbourne, Australia. Thirty multidisciplinary oncology healthcare professionals (HCPs) participated in an initial test of VR intervention usability (Stage 1). Ninety oncology inpatients (7-19 years) and their parent caregivers participated in a pilot randomized controlled study to examine the effectiveness of an Immersive VR therapeutic intervention (Stage 2). This mixed methods study reports Stage 1 & 2 quantitative and qualitative data related to VR feasibility and acceptability. Results: Results indicate favorable perceptions from HCPs with respect to ease of use and usefulness of VR, and had positive intentions to use it in the future. Parent caregivers reported highly acceptability of VR for their hospitalized child. Patients reported high satisfaction of the VR intervention within minimal adverse effects. Barriers and facilitators to VR use with seriously ill children and specific recommendations for content development were elicited. Conclusion: This study shows there are several potential clinical uses for Immersive VR intervention, beyond medical procedural distraction, to support psychological adjustment to hospitalization and patient quality of life.

Association study of the beta-adrenergic receptor genetic variant Gly389Arg and fluoxetine response in major depression
Authors: Firouzabadi Negar , Asadpour Roja , Zomorrodian Kamiar
Published: March 2020

Background: Pharmacogenetics has proven role in the treatment of different illnesses. Patients with special genotypes may achieve a better response to a specific drug. On the other hand, genetic parameters markedly contribute to the development of major depressive disorder (MDD). The significance of adrenergic system compartments in cognition and behavior, and their role in etiology of depression denote that adrenergic receptors beta gene polymorphism(s) might also have an association with drug response. Thus this study aims to evaluate the association between β1AR gene polymorphisms, G1165C, Arg389Gly and response to fluoxetine in MDD patients. Materials and Methods: Among different antidepressants, we focused on fluoxetine as it is prescribed frequently in MDD and belongs to one of the most efficient antidepressant categories with minimum side effects. MDD was diagnosed at study entry using DSM-IV criteria. One hundred and one new MDD patients were treated with fluoxetine for a period of 6 weeks. A 50% decrease in Hamilton Rating Scale for Depression (HRSD) was considered as response to treatment. Genotyping of G1165C polymorphism was performed by PCR-RFLP method. Results: Results of the study indicated no significant relationship between β1AR polymorphism and the patient’s response to fluoxetine neither at genotypic nor allelic level (P=0.568). Conclusion: Our study did not support the hypothesis of involvement of β1AR Arg389Gly polymorphism and response to fluoxetine in MDD patients. [GMJ.2020;9:e1781]
Normative policy coherence for development and policy networks
Authors: Häbel Sandra
Published: March 2020

English abstract: The European Union (EU) is often understood as a normative power. However, based on a case study of European policy networks in Vietnam, this article shows that despite the EU’s commitment to norms and transformative development, norms are not a priority in the implementation of development policies. Rather, norm promotion is delegated to political and diplomatic representatives, whereas development and trade representatives are responsible for technical work. Consequently, policy networks created around these four sectors tend to operate separately from each other, undermining the spillover of norms from diplomatic and political networks to development and trade networks. As a result, this article shows that the structural–institutional separation of sectoral policy networks is one of the EU’s systemic characteristics that restrict normative policy coherence for development.

Spanish abstract: La Unión Europea (UE) es considerada un poder normativo, comprometida con las normas y el desarrollo transformativo. En cambio, usando un caso de estudio de redes europeas políticas en Vietnam, este artículo demuestra que las normas no son prioridad en la implementación de políticas de desarrollo. Al contrario, la promoción de normas se delega a representantes políticos y diplomáticos, mientras que los representantes del desarrollo y comercio se hacen cargo del trabajo técnico. Consecuentemente las redes políticas de estos cuatro sectores tienden a aislarse, dificultando la transferencia de las normas de redes políticas y diplomáticas a redes de desarrollo y comercio. El resultado demuestra que la separación estructuro–institucional de las redes políticas sectoriales es una de las características sistémicas de la UE que restringen la coherencia normativa de políticas para el desarrollo.

French abstract: L’Union européenne est souvent considérée comme une puissance normative. Cependant, sur la base d’une étude de cas de réseaux de politiques publiques au Vietnam, cet article montre que, malgré son engagement normatif et de développement réformateur, les normes ne sont pas une priorité dans la mise en oeuvre des politiques de développement. Au contraire, leur promotion est déléguée aux représentants politiques et diplomatiques, tandis que les représentants du développement et du commerce sont responsables des travaux techniques. Par conséquent, les réseaux politiques créés autour de ces quatre secteurs ont tendance à fonctionner séparément les uns des autres, ce qui compromet le transfert des normes des réseaux diplomatiques et politiques aux réseaux de développement et du commerce. Ainsi, cet article montre que la séparation structuro-institutionnelle des réseaux sectoriels de politiques publiques est l’une des caractéristiques systémiques de l’UE qui restreint leur cohérence normative en matière de développement.

Functional multi-track and multilevel economic diplomacy to strengthen trade relations between Indonesia, Chile, and Peru
Authors: Tobing Fredy B.L. , Virgianita Asra
Published: March 2020

English abstract:
This article analyzes the causes of low trade relations between Indonesia and Latin American states, arguing that dynamics of international political economy have opened opportunities to increase trade relations between those countries. Having good diplomatic and political relations with similar emerging economies, like Peru and Chile, should drive closer economic relations among them. A qualitative study was conducted using literature reviews, archival analysis, and in-depth interviews. Political will and lack of knowledge pertaining to the business character of each country hamper external relations. Thus, a functional multi-track diplomacy that incorporates state and non-state actors from various fields is crucial for enhancing economic relations among these countries. Trade relations can be particularly strengthened by maximizing cooperation among actors at various levels.

Spanish abstract:
Este artículo analiza las débiles relaciones comerciales entre Indonesia y América Latina, argumentando que la dinámica de la economía política abre oportunidades para mejorar estas relaciones. Las buenas relaciones diplomáticas y políticas entre Perú y Chile, debería estrechar sus relaciones económicas. Pero la escasa voluntad política y falta de conocimiento del carácter empresarial de cada país, obstaculizan sus relaciones externas. La investigación incluyó revisión de literatura, análisis de archivos y entrevistas en profundidad. Los resultados subrayan la necesidad de una diplomacia funcional de múltiples rutas que incorpore instituciones estatales y no estatales de diversos campos para mejorar las relaciones económicas. Las relaciones comerciales particularmente pueden fortalecerse entre países maximizando su recíproca cooperación en cada nivel (diplomacia multinivel).

Cette étude qualitative a été menée sur la base d’une étude de la littérature existante, d’analyses archivistiques et d’entretiens approfondis. Le manque de volonté politique et surtout de connaissances réciproques des atouts commerciaux de ces pays entravent leurs relations extérieures. Ainsi, une diplomatie fonctionnelle à plusieurs voies qui intègre des diplomaties étatiques et non-étatiques dans divers domaines est-elle cruciale pour améliorer leurs relations économiques. Les relations commerciales peuvent notamment être renforcées en maximisant la coopération entre ces pays à chaque niveau (diplomatie multi-niveaux).

OBJECTIVE

Posthemorrhagic hydrocephalus of prematurity remains a significant problem in preterm infants. In the literature, there is a scarcity of data on the early disease process, when neurosurgeons are typically consulted for recommendations on treatment. Here, the authors sought to evaluate functional outcomes in premature infants at 2 years of age following treatment for posthemorrhagic hydrocephalus. Their goal was to determine the relationship between factors identifiable at the time of the initial neurosurgical consult and outcomes of patients when they are 2 years of age.

METHODS

The authors performed a retrospective chart review of premature infants treated for intraventricular hemorrhage (IVH) of prematurity (grade III and IV) between 2003 and 2014. Information from three time points (birth, first neurosurgical consult, and 2 years of age) was collected on each patient. Logistic regression analysis was performed to determine the association between variables known at the time of the first neurosurgical consult and each of the outcome variables.

RESULTS

One hundred thirty patients were selected for analysis. At 2 years of age, 16% of the patients had died, 88% had cerebral palsy/developmental delay (CP), 48% were nonverbal, 55% were nonambulatory, 33% had epilepsy, and 41% had visual impairment. In the logistic regression analysis, IVH grade was an independent predictor of CP (p = 0.004), which had an estimated probability of occurrence of 74% in grade III and 96% in grade IV. Sepsis at or before the time of consult was an independent predictor of visual impairment (p = 0.024), which had an estimated probability of 58%. IVH grade was an independent predictor of epilepsy (p = 0.026), which had an estimated probability of 18% in grade III and 43% in grade IV. The IVH grade was also an independent predictor of verbal function (p = 0.007), which had an estimated probability of 68% in grade III versus 41% in grade IV. A higher weeks gestational age (WGA) at birth was an independent predictor of the ability to ambulate (p = 0.0014), which had an estimated probability of 15% at 22 WGA and up to 98% at 36 WGA. The need for oscillating ventilation at consult was an independent predictor of death before 2 years of age (p = 0.001), which had an estimated probability of 42% in patients needing oscillating ventilation versus 13% in those who did not.

CONCLUSIONS

IVH grade was consistently an independent predictor of functional outcomes at 2 years. Gestational age at birth, sepsis, and the need for oscillating ventilation may also predict worse functional outcomes.

OBJECTIVE

The carotid cave is a unique intradural region located along the medial aspect of the internal carotid artery. Small carotid cave aneurysms confined within this space are bound by the carotid sulcus of the sphenoid bone and are thought to have a low risk of rupture or growth. However, there is a lack of data on the natural history of this subset of aneurysms.

METHODS

The authors present a retrospective case series of 290 small (≤ 4 mm) carotid cave aneurysms evaluated and managed at their institution between January 2000 and June 2017.

RESULTS

No patient presented with a subarachnoid hemorrhage attributable to a carotid cave aneurysm, and there were no instances of aneurysm rupture or growth during 911.0 aneurysm-years of clinical follow-up or 726.3 aneurysm-years of imaging follow-up, respectively.

CONCLUSIONS

This series demonstrates the benign nature of small carotid cave aneurysms.

Authors: Starodub Yu. , Bagnyuk V.
Published: March 2020

The article deals with the process of parameters estimation of the flood zone at the dam break or its destruction, and a scale of possible destruction caused by possible emergencies. Modeling is carried out for the time of approach of the breakthrough wave to a given distance, the height of the breakthrough wave, the time of discharge of the reservoir, the duration of the passage of the wave at a predetermined distance for buildings and structures in the area of shock wave. The example is done for the dam of the Middle Dnieper hydroelectric power station. A technique for modeling a hazardous situation related to the consequences of a breakthrough of the dam at the Middle Dnieper Hydropower Plant has been developed. The prediction and simulation is based on the phenomenological parameters of the Kamyansky reservoir.The simulation of the assessment of the engineering environment for the dam of the Serednyodniprovska hydroelectric power station was carried out using the parameters of flooding of the terrain. Parameters used - the possible maximum depth of flooding, the width of flooding and the rate of water flow at the break of the dam, the time of arrival of the wave front, the crest and tail of the break wave, maximal flow dams, wave heights above water level above domestic flow. As a result, the maximum flooded area was estimated.Based on the use of dam and reservoir characteristics and the use of appropriate formulas for calculating emergency factors and using modeling using ArcGIS, the possible topographic consequences of the breakthrough of the dam in the city Kamianske and the locations of industrial enterprises in its vicinity were obtained. The latter enables rescue services to promptly assess the threat of an emergency in the event of an emergency, to have an idea of the consequences in order to take preemptive measures to prevent the occurrence of an emergency.

Published: March 2020

Issues of combating hazardous fire factors such as smoke and heat, which are being fought by the firefighters whit self-contained breathing apparatus (SCBA units) of State Emergency Service of Ukraine, remains one of the complicated tasks which should be solved by the operational units. The concentration of toxic substances in the first minutes of the fire are 12-100 times above the maximum. The average volume temperature in the first 5-10 minutes of fire can reach 140-900 оС. The rate of smoke spreading and toxic substances is very high. Every year, about 16 per 1 million people worldwide die from the cause of poisoning by combustion products during the fire, moreover, this trend is increasing every year.

Therefore, the effectiveness of rescuing people, eliminating fires and carrying out rescue operations in the non-breathable environment depends, largely, on the speed of carrying out such operative actions, with the help of technical means one of which is a thermal imaging camera (TIC). As foreign practice shows, firefighters have widely used TICs during firefighting, searching victims and reconnaissance, however, in Ukraine, these devices have only just begun to appear in SES units. Thus, the study of the assessment of the parameters of TICs and their subsequent comparison is an urgent scientific task. The solving of which makes it possible to improve the efficiency of fire elimination during firefighting with zero visibility and a large number of combustion products by the SCBA units. Accordingly, there is a need for developing an assessment technique of the TIC parameters, which ensure the effectiveness of reconnaissance, searching the sources of fire and rescue operations by the SCBA units.

The article describes the assessment methodology for estimating the parameters of TICs, according to which will be conducted experimental studies based on the fire module of Lviv State University of Life Safety. The aims of this study will identify the influence of fire environmental on the parameters of the TICs and on the efficiency of the reconnaissance process by the SCBA units in order to detect the fire cell and other issues.

Published: March 2020

Introduction. According to the information of the State Labor Office of Ukraine, over the 12 months of 2018, 59 persons were injured at the enterprises of the water supply and sewerage system of Ukraine, including 2 persons were fatally injured. Within 5 months of 2019, 16 people were injured, with 4 deaths.

Water and sewerage managements of Ukraine is one of the most important systems of life support of settlements. Much of the water supply and sewerage network is in a state of disrepair and needs to be replaced and repaired. With the onset of summer, the intensity of repair, excavation and cleaning works, work in wells, ditches, trenches, closed spaces increases, which in turn increases the likelihood of accidents occurring during their execution.

Appointment. Limited (closed) spaces include tanks (tanks, tanks, boilers), wells, chimneys, narrow passageways in tunnels and cellars, and the like.

EAOUW - emergency and other urgent work.

Feature of EAOUW in confined spaces is:

- the possibility of accumulation of gaseous hazardous chemicals in high concentrations, explosive and poisonous gases, as a con- the difficulty of accessing rescuers to victims;

- limited amount of time for EAOUW;

- probability of landslides (landslides) during actions in earth wells;

- a sharp rise in groundwater and displacement of the well rings;

- threat of explosion or fire.

Methods. As the equipment of the climbing and special rescue equipment of the units of the operational and rescue service of civil protection is different, we will consider the use of the system of polyspast during rescue operations in a limited space (underground collectors, wells).

Results. Three experiments were conducted on the use of the polyspast system during emergency rescue and other emergency work in a confined space (underground collectors, wells).

Conclusion.Having analyzed the above-mentioned facts of accidents at work in underground collectors, wells and standard of accessory, costs and terms of operation of fire-rescue, technological and garage equipment, tools, individual armament and equipment, repair and operational materials of subdivisions of Ukraine mounting method of polyspast system with different equipment. Particular attention should be paid to the third experience, namely the mounting of a polyspast system using six fire carbines and a rope.

This study aims to determine whether perceptions of corruption and organizational climate affect the compliance of personal taxpayers. This explanatory study used quantitative approach of statistical parametric test and multiple linear regressions with questionnaire instrument. This study involved personal taxpayer in the area of KPP Pratama Kota Surakarta. The result of this study confirms that the perceptions of individual tax corruption and organizational climate affect the compliance of personal taxpayers. The better the organization’s climate in emphasizing tax compliance is, the higher the level of compliance personal taxpayers is. In addition, the higher the level of perception of a person’s corruption of the tax apparatus is severely punished then increasing the compliance of personal taxpayers’ increases.

Published: March 2020

Background: Hyperbilirubinemia is one of the most prevalent problems in neonates. Jaundice is observed during the 1st week of life in approximately 60% of term neonates and 80% of preterm neonates. Phototherapy is one of the routine methods for the management of hyperbilirubinemia. Objective: The objective of this study was to assess the effect of phototherapy on serum calcium levels in term newborns with neonatal hyperbilirubinemia. Materials and Methods: Full-term newborns admitted in the postnatal ward with hyperbilirubinemia were included in the study population. Serum calcium estimation was done before phototherapy and all newborns were subjected to double surface phototherapy. After 24–48 h of phototherapy, serum calcium was estimated again and compared with the earlier value. Results: A total of 50 newborns were included in the study. After phototherapy, serum calcium levels were 7.31–7.60 mg/dl in 20 newborns, 7.61–7.90 mg/dl in 19 newborns, 7.0–7.30 mg/dl in 7 newborns, and 7.91–8.20 mg/dl in 4 newborns. This reduction in calcium level was found to be statistically significant (p<0.05). None of them were symptomatic. Conclusion: This implies that decrease in calcium levels is one of the major complications of phototherapy. It was also identified in the study that the babies given phototherapy for longer duration showed higher chances of hypocalcemia.

Published: March 2020

Background: The most important changes during puberty are secondary sexual characters. Objective: The objective of this study was to find out the mean testicular volume (MTV) by Prader orchidometer at different stages of pubertal development. Materials and Methods: Children between 10 and 18 years of age (sample size 525) from schools of Udaipur city were included in the study. Children, who underwent major surgery or having any systemic disorders, were excluded from the study. TV assessment was done by Prader’s orchidometer with Tanner staging and correlation was statistically analyzed. Results: The maximum boys belonged to 15–16 years of age group (14.7%), and 9.3% of boys were in 10–11 years of age group. The secondary sexual characters were observed to increase with the increase in MTV. The MTV for P1 was 4.46 ml, for P5 was 22.68 ml, and for G1 and G5, it was 4.69 ml and 23.27 ml, respectively (p<0.05). Conclusion: TV adds more objectivity in the detection of sexual maturation and helps to differentiate early genital maturation than pubic hair. The study population had an early rise of TV before pubic hairs were clinically visible which showed that it was the first to increase with the onset of puberty.

Published: March 2020

Background: The neonatal unit equipment generates noise which is detrimental to neonatal physiological homeostasis and development. The incubator is one such essential component of modern neonatal care which, on the one hand, provides a low noise environment and also intrinsically generates noise. Objectives: The objectives of the study were to test the hypothesis that the neonatal incubator provided a better acoustic environment with lesser noise levels than the external environment. Materials and Methods: A prospective observational study was done in a Level III neonatal unit for 4 months from April 15, 2016, to August 15, 2016. Baseline noise levels of the various equipment inside a working incubator were recorded using a sound level meter. Subsequently, hourly noise levels in the neonatal intensive care unit (NICU) and inside the Giraffe Omnibed Incubator were recorded simultaneously as equivalent Continuous Sound Pressure Level as loudness equivalent. Two digital sound level meters were used. Noise levels inside and outside the incubators were used as a grouping variable. Chi-square test was used for categorical variables and independent t-test for continuous variables. All tests were two tailed and p<0.05 was considered statistically significant. Results: The noise levels recorded both inside the incubator and the NICU were >58 dbA for most times of the day. The noise levels inside the incubator were significantly less (p<0.05) than the outside. Conclusion: The statistically significant noise reduction inside the incubator provides a better acoustic environment for neonates.
