Investigation of welded protective covers for heat treatment
Authors: Jármai Károly , Szűcs Renáta 
Published: August 2020

Abstract
A welded steel protective cover used for the heat treatment of steel sheet coils is investigated. The protective cover is made of austenitic stainless steel and consists of three main segments, welded together, which have 1400 mm height each. The plate thicknesses at the lower, middle and upper segments are different. The investigation aimed to improve the lifetime and the number of heat cycles of the protective cover by changing the geometry, the effect of the thicknesses and the material. Damaged covers have been evaluated, made calculations of stress and deformations, and carried out a series of finite element simulations. Both horizontal and vertical corrugated sheets were simulated and compared. The non-corrugated plates were also investigated, but their performance was behind the corrugated ones. The original geometry and that of the horizontal corrugated plate are identical from the stress level point of view. The vertical position of the corrugated plate provided a better result than the horizontal one. The calculated and simulated results for the original geometry are close to the measured damage.

Published: August 2020

Abstract
The possibility of using mineral admixtures as a replacement for cement may reduce the carbon dioxide emission, which causes global warming and climatic changes on the environment. The objective of this study is to investigate the properties of early strength concrete produced with a constant replacement of alccofine (i.e. 25% by mass) and a new generation of chemical admixture that is Polycarboxylate ether. The constant dosage of alccofine and different proportions of polycarboxylate ethers are mixed in concrete and tested for workability and mechanical properties of concrete. Response surface method was applied to predict, validate and optimize the experimental data using regression equation. The results show that the performance of concrete improves with the addition of alccofine and Polycarboxylate ether into concrete.
Comparison of two approaches for an estimation of the mean annual flood at ungauged sites in Slovakia
Authors: Németová Zuzana , Kohnová Silvia , Marková Romana 
Published: August 2020

AbstractRegional flood frequency analysis is considered to be an important and popular method for estimating different hydrological variables at ungauged sites. The estimation of the index flood is the essential problem when this method is applied. The objective of the study is a comparison of the estimation of the mean annual flood (or index flood) by using two approaches based on the ‘so-called’ index flood method and top-kriging. The concept behind these methods permits estimating the mean annual flood at ungauged locations using information taken from gauged sites located within the same homogeneous pooling groups. The study area comprises 104 gauging stations on the whole territory of Slovakia. The observation period of the annual maximum discharges of the selected stations was from 1961-2010. The identification of the homogeneous pooling group was performed using a non-hierarchical k-means clustering algorithm. The optimal number of clusters is determined by the Silhouette method. As a result, eight homogeneous pooling group clusters were identified. Finally, the results of the estimated mean annual floods using the index flood method and top-kriging were compared with the observed data. Top-kriging provided better results than the classical index flood method for estimating the mean annual flood at ungauged sites.

Published: August 2020

Abstract:A building physics supported development was undertaken for the new block of the University of Pécs, Medical School. During sketch design stage climate, lighting and energy simulations were applied to quantify energy optimization strategies. Simulation cases assess the impact of shading technologies, wall-window ratios and thermal masses on used thermal energy demand. Based on a previous study about visual and comfort performance, goal was to identify the highest energy efficiency rates with maximum investment cost savings. Besides best comfort results, the most optimal development represents 9% saving in used thermal energy, and they were proposed for further design.

We aimed for assessing effects of immunocytotherapy upon the subpopulations of CD4+CD25highFoxP3+cellswithnaturalregulatoryactivityandactivatedTh17cellswiththeCD4+CD25highRORγt+phenotype, as well as in vitro production of cytokines in mitogen-stimulated cells from peripheral blood in the patients with idiopathic habitual miscarriage (IHM). The study group consisted of 33 patients with IHM who became pregnant after a pre-gestational alloimmunization. In 27 patients, the pregnancy was prolonged to the full term and ended with the birth of viable babies, in six cases it was terminated before 12 weeks of gestation. Before administration of immunocytotherapy (ICT), 19 patients were examined, of them 16 after alloimmunization outside of pregnancy, 17 at 5-6 and 8-9 weeks of pregnancy. Eleven patients were immunized at 12 weeks of pregnancy. In the control group, 12 fertile women outside pregnancy and 10 women at 12 weeks of physiological pregnancy were examined. The proportion of FoxP3+and RORγt+cells with the CD4+CD25highphenotype was evaluated among T-lymphocytes from peripheral blood, as well as content of proinflammatory cytokines (IFNγ, TNFα, IL-1β, IL-2, IL-5, IL -6, IL-8, IL-12p70) and anti-inflammatory factors (IL-4, IL-10), as well as IL-17 amounts.We have found that, following pre-gestational alloimmunization, the women who lost this pregnancy, had a low level of FoxP3+Тregs that suppress pro-inflammatory Th17-dependent reactions, however, without changing levels of activated Th17 cells (CD4+CD25highRORγt+ lymphocytes). These facts, along with high in vitro production of IL-17 by peripheral blood cells at the terms of 5-6 weeks of gestation, suggest that, after pre-gestational alloimmunization in women with miscarriage, a predilection is formed to pro-inflammatory cytokine production. However, at the 5-6 week-period, it is realized not in the Th1 direction of, but towards Th17 response, and a low level of CD4+CD25highRORγt+cells may reflect an increased migration of Th17 cells from peripheral blood to the uterine endometrium.Thus, we have shown the effect of immunocytotherapy upon subpopulational composition of peripheral blood lymphocytes and the cytokine profile, as well as upon the course of first trimester and outcomes of pregnancy in women with idiopathic habitual miscarriage.

The use of whole genome sequencing, standard analyze methods and international databases allows to detect international high-risk clones of food-borne pathogens, to assess their evolution and geographical distribution due to international trade of animal food products and farm animals. In Saint-Petersburg, Russian Federation, Salmonella Newport, Salmonella Kentucky and Escherichia coli O26:H11 of well-known international high-risk clones were first identified from patients with diarrhea. Two S. Kentucky strains isolated in 2015 and 2019 were identical to the international clone ST198 widely distributed in European countries: had multidrug resistance, high-level fluoroquinolone resistance (MIC of ciprofloxacin 32,0 mg/l) due to three single-nucleotide substitutions in the gyrA (Ser83Phe and Asp87Asn) and parC (Ser80Ile). In 2008, a multidrug resistant S. Newport strain resistant to extended-spectrum cephalosporins due to AmpC-cephalosporinase CMY-2 was isolated, belonging to the international clone of S. Newport MDR-AmpC/CMY-2 which caused sporadic cases and outbreaks in the USA and Europe in the 2000s. The plasmid containing the blaCMY-2 had a PstI-restriction profile, one of the most prevalent in the international clone. E. coli O26:H11 strains, isolated in Saint-Petersburg, produced the shiga-like toxin STX1 (stx1a), had additional virulence genes: ehxA (enterohemolysin), katP (catalase peroxidase), espP (serine protease), as well as cba (colicin B), gad (glutamate decarboxylase), cif (type III secreted effector), iss (increased serum survival), belonged to the phylogenetic group B1 and the international high-risk clone E. coli O26:H11 ST21 widely distributed in Europe and the USA. 25% of the strains had multidrug resistance and produced CTX-M extended spectrum beta-lactamases. In the Russian Federation E. coli O26 is consider as the pathogen of diarrheal diseases and registered as Enteropathogenic E. coli in routine bacteriological laboratories without detecting of H-antigen and shiga-like toxins.

COVID - 19 - a New Challenging Disease for Intensivists and Cardiologists. From Basic Science to the Clinical Setting
Authors: Skalik Robert 
Published: August 2020

A novel coronavirus causing Acute Respiratory Distress Syndrome (SARS-CoV-2) has been considered the cause of a large number of lower respiratory tract infections leading to severe respiratory failure in many cases. However, the evidence-based hospital reports show that the COVID -19 infestation may range from an asymptomatic or minimally symptomatic course with an almost bizarre deterioration of life parameters (“silent hypoxia”) through to critically ill patients with multiple organ failure including that of the lungs, kidneys, nervous system and other organs. Moreover, this coronavirus disease may cause significant lung damage in asymptomatic COVID-19 positive patients who recover at home.The virus enters through the angiotensin-converting enzyme 2 receptor (ACE2) widely expressed in the cardiovascular system and other organs and tissues, which can result in myocardial injury, myocarditis, acute myocardial infarction, heart failure, arrhythmias, brain stroke, acute pleuritis, pneumonia and venous thromboembolic events. COVID -19 - induced failure of some central mechanisms controlling breathing and the circulation may explain the mismatch between the clinical symptoms and the objective physiologic life parameters in many patients treated by intensivists or cardiologists. The severity of coronavirus disease is dependent on numerous factors including the magnitude of the host immune response, the impairment of central and peripheral nervous system, age, co-morbidities (e.g. diabetes, arterial hypertension, obesity, chronic heart failure) and presumably genetic proclivity. A brand-new treatment approach with use of alternative or experimental therapies such us Extracorporeal Membrane Oxygenation (ECMO), plasmapheresis, proinflammatory interleukins - targeted drugs, covalescent plasma transfusion, virus replication inhibitors is obviously needed in some COVID-19 patients.

Published: August 2020

This study aims to describe and analyze the implementation of protection policies for women and children in Makassar City. This study uses a qualitative design and case study strategy to explain the implementation of policies for protecting women and children in the Makassar City of Makassar. Data collection techniques used were observation, depth-interviews, and documentation. The data processing technique used is data reduction through data categorization and classification. Based on the results of research on the implementation of policies on the protection of women and children in the Office of Women's Empowerment and Child Protection, Makassar City is still not optimal. This is caused by the accuracy of the budget allocation, even though it is in accordance with the program prepared but not yet in accordance with the existing budgetary needs. Internal public support, especially community shelters, is still low and depends on the operational budget of the operational budget of the APBD, another weakness lies in the ability of the executive officer to evaluate the community shelter who are not active and the ability to convince the private sector and donor agencies. It is recommended to strengthen the institutions responsible for implementing policies on the protection of women and children, especially P2TP2A, TRC and community shelters in the form of budget availability, supporting facilities and technical authority in collaboration and innovation.

Published: August 2020

Abstract
Background: Undifferentiated connective tissue disease (UCTD) is known to induce adverse pregnancy outcomes, and even recurrent spontaneous abortion (RSA) by placental vascular damage and inflammation activation. Anticoagulation can prevent pregnancy morbidities. However, it is unknown whether the addition of immune suppressant to anticoagulation can prevent spontaneous pregnancy loss in UCTD patients. The purpose of this study is to evaluate the efficacy of hydroxychloroquine (HCQ) and low-dose prednisone on recurrent pregnancy loss for women with UCTD.Methods: The Immunosuppressant for Living Fetuses (ILIFE) Trial is a three-arm, multicenter, open-label randomized controlled trial with the primary objective of comparing hydroxychloroquine combined with low-dose prednisone and anticoagulation with anticoagulation alone in treating UCTD women with recurrent spontaneous abortion. The third arm of using hydroxychloroquine combined with anticoagulant for secondary comparison. A total of 426 eligible patients will be randomly assigned to each of the three arms with a 1:1:1 allocation ratio. The primary outcome is the rate of live births. Secondary outcomes include adverse pregnancy outcomes and progression of UCTD.Discussion: This is the first multi-center, open-label, randomized controlled trial which evaluates the efficacy of immunosuppressant regimens on pregnancy outcomes and UCTD progression. It will provide evidence on whether the immunosuppressant ameliorates the pregnancy prognosis in UCTD patients with RSA and the progression into defined connective tissue disease.

Building research capacity in musculoskeletal health: qualitative evaluation of a graduate Nurse and Allied Health Professional internship programme
Authors: Wright David , Fry Mary , Adams Jo , Bowen Catherine 
Published: August 2020

Abstract
Background: Evidence based practice enhances service planning and delivery, clinical decision making and patient care. However, health professionals often lack the time and opportunity to access or generate evidence. Research capacity building is thus an important mechanism for improving health service delivery. This study evaluates the effectiveness of a UK-wide Nurse and Allied Health Professional musculoskeletal research internship programme in which graduates applied to undertake their internship through one of five Higher Education Institutions. The evaluation explores the experiences of interns and their mentors. Methods: Sixteen new graduates completed the internship programme (September 2015 – August 2018). Twelve interns and thirteen mentors participated in the evaluation. The evaluation used qualitative asynchronous email-based interviews to explore the experiences of interns and mentors. Interpretive phenomenological analysis of coded transcripts identified principal themes. Results: Early research outputs from the interns include three peer reviewed publications and 21 conference abstract presentations. Two interns were in full time research at the time of interview or had a research component in their clinical role. Nine interns in clinical posts disclosed plans to return to research in the near future. Seven themes were identified: the impact on interns’ careers; personal impact (for example, influence on self-confidence); impact on clinical practice; drivers for applying; intervention design (for example, attitudes concerning the timing and duration of the intervention); mentorship and networking (including general support provided and quality of career advice); challenges. Conclusion: The internship programme is an effective model in building research capacity in musculoskeletal research for Nurses and Allied Health Professionals, influencing careers, building confidence and improving clinical practice. The internship programme has the potential to be replicable to other clinical contexts nationally and internationally.
