Published: June 2021

Composite of such renewable material as timber and the most popular man-made material as concrete offers many benefits. Such of them are high load-bearing capacity with low dead load and increased structural bending stiffness. Higher specific strength of high-performance concrete in comparison with ordinary concrete ensures more efficient use of the material. Addition of fibres can reduce the fragility and autogenous shrinkage cracks of high-performance concrete and makes it possible to design thinner layers of concrete for timber-concrete composite structures. Ribbed slabs as solution for the floor slabs, allows to reduce material consumption and to integrate engineering communications into the structures. The current study focuses on determining the effect of the use of high-performance fibre reinforced concrete for timber-concrete composite ribbed slabs with adhesive connection between layers, as the most effective connection type for composite action. The effect of the use of high-performance fibre reinforced concrete is determined by comparison of mid-span displacements of the ribbed slabs numerical models. Three-dimensional finite element models of timber and ordinary concrete composite ribbed slab and high-performance fibre reinforced concrete with additional longitudinal reinforcement ribbed slab are validated by experiment data. Developed numerical models makes it possible to predict the dependence of applied load on mid-span displacement in three-point bending with sufficient precision. Obtained results showed, that replacement of ordinary concrete layer by high-performance fibre reinforced concrete in timber-concrete composite ribbed slab with adhesive connection up to 1.68 times decrease vertical mid-span displacements.

Published: June 2021

For more than 40 years, low calcium alkali-activated cement composite, or in other words, geopolymer, has been around. In recent years there has been increased interest in this material and its properties. It is mainly due to the claim that geopolymer is the cement of the future. This claim is based on environmental factors. For instance, the CO2 emissions for geopolymer binder can be up to 6 less than for Portland cement binder. Most of the researches regarding geopolymer composite properties examine only mechanical and long-term properties in compression. There has been a lack of long-term tests in tension due to difficulties in performing them. As the tensile stresses are an essential part of structure assessment, it is necessary to evaluate new material properties as thoroughly as possible. Due to the nature of geopolymer specimen hardening (polymerisation), there is a difference in modulus of elasticity development and shrinkage caused by binding that could have factors that regular Portland cement specimens do not.This article aims to evaluate the surface composition of plain and 1% PVA reinforced geopolymer compact tension specimens that have been subjected to creep and shrinkage tests. Specimen cross-section images were acquired using the scanning electron microscope (SEM). Using the quantitative image analysis method, amounts of cross-section composition elements are determined. Furthermore, the amount of cracks is determined and compared between plain and PVA fiber-reinforced specimens.It has been determined that even though 1% of PVA fibre-reinforced specimens have lower tensile strength, their creep and shrinkage strains are lower, and the number of microcracks at the notch base of the specimen. Still, it has to be acknowledged that the amount of air voids in all analysed specimens is relatively high.

Authors: Miklašēvičs Ziedonis
Published: June 2021

Among different development directions for better forest utilization, the purposefully detailed assessment of wood quality as raw material, faciliating improved wood utilization in manufacturing of traditional roundwood products as well as brand new products, proves to be very perspective. Roundwood quality features substantially differ depending on forest stand geographic location, growing site conditions, tending of forest stands and other circumstances [2], [3], [11]. Therefore, the economical estimation of more important tree species in Latvia should not be based only on scientific conclusions made in other countries, so particular research is needed for this purpose. Pine (Pinus sylvestris) is the most widespread tree species in Latvia, therefore a research work provided the characteristic of round wood obtained from pine tree stem is an actual point from several aspects, as it is necessary;to create early prediction models of roundwood quality; to plan harvesting purposes;to create the data basis of economically more relevant domestic tree species;to provide the further development of roundwood quality assessment methods;to estimate the competitiveness of Latvia pine timber in the world marketThe main goal of study is to work out the quality characteristic of pine roundwood manufactured in final felling sites depending on timber formation damages- bark abrasion caused side drought.

Published: June 2021

The microstructure and mechanical properties of high chromium white cast iron with composition: 2,6÷3,4% C; 0,9÷1,1% Si; 0,8÷1,1% Mn; 1,0÷1,3% Mo; 12,3÷13,4% Cr, additionally doped with boron in an amount of 0,18% to 1,25% is investigated. The microstructure of six compositions of white cast irons is studied by means of an optical metallographic analysis - one without boron, and the others contain 0,18%; 0,23%; 0,59%; 0,96% and 1,25% boron. A test is performed to determine: hardness by the Rockwell method; microhardness; bending strength and impact toughness. It was found that at a boron content of 0,18%; 0,23% and 0,59%, the structure of white cast irons is subeutectic, with impact toughness in the range of 1,80÷1,52 J/cm2; with a boron content of 0,96%, the structure of white cast iron is close to the eutectic, with impact toughness 0,98 J/cm2 ; at a boron content of 1,25% the structure of white cast iron is supereutectic and the impact toughness decreases to 0,68 J/cm2. With a change in the boron content from 0,8% to 1,25%, the amount of carbide phase in the structure of white cast iron increases, which leads to an increase in hardness from 53 to 59 HRC. The highest bending strength (Rmi=660,85 MPa) was obtained in white cast irons with a boron content of 0,23%.

Published: June 2021

Foreign experience in the use of radiopharmaceuticals has provedthe diagnostic accuracy in identifying kidney, heart, lungs, soft tissues and blood vessels disease. Scintigraphy could beused to detect morphofunctional changes inorgans ororgan systems, as well as metabolic disorders by means of radiation dose rate received afterthe radiopharmaceutical administration. For example, Technetium-99 (99m Tc) is appliedto identifyincomplete bone fractures in unproductive animals and sports horses; hypothyroidism and malignant neoplasms affecting the thyroid gland in dogs; hyperthyroidism in cats. To date, scintigraphy is rarely used in domestic veterinary practice due to a number of reasons. High cost of radionuclides; the need to comply with safety requirements, in accordance with the Guideline 2.6.1.1892-04 dated March 04, 2004; the lack of additional veterinary specialist training. The most significant point is that animals injected with a radioactive compound or implanted with radioactive sources can be returnedto the owner only after the activity of radionuclides in the body (GBq) reducedenough to meet the requirements of Sanitary Regulations and Norms2.6.2523-09 Radiation Safety Standards (NRB-99/2009) dated July 07, 2009.
It should be noted that radiopharmaceutical drugs have not been approved for use in productive animals in the USA to date. As additional financial and human resources are required to control the number of residual nuclides in livestock products, resulting in production costs increase.
Steroid hormones and their metabolites in water of centralized drinking water supply systems as ecopolutants
Authors: Vengerovich Nikolay G. , Perelygin Vladimir V.
Published: June 2021

Information about the presence of drugs and their metabolites in the water of centralized drinking water supply systems is presented; the main groups of drugs found in purified drinking water of large cities are given. The main groups of drugs found in a centralized drinking water supply system include antidepressants (amitriptyllin), antibacterial drugs of various groups (amoxicillin, ciprofloxacin, tetracycline, azithromycin), narcotic analgesics (cocaine, morphine, their derivatives), psychoactive stimulants, benzodiazepines, hormones (estrogen and its metabolites estrone and estriol).
A high level of potential risk to public health is marked due to the presence of steroid hormones and their active metabolites in drinking water. The concept of endocrine dysregulating complexes is formulated. Such complexes can be of a different nature of origin, but all of them affect receptors for estrogen and progesterone. It leads to abnormalities of hormonal regulation, affects endogenous synthesis, transport and secretory function.
From the standpoint of ecotoxicology, further ways of working out the problem of the presence of steroid hormones in drinking water are proposed: the development of theoretical approaches to substantiating hygienic standards concerning the monitoring of these compounds in the water of centralized drinking water supply systems.

Published: June 2021

This article is devoted to the patterns of changes in the QRS complex and the ST-T segment in patients with a new coronavirus infection. The article presents the results of a comparison of electrocardiogram data in 70 patients with COVID-19 who were treated in 1st Department of Internal Medicine Postgraduate Training from April to July 2020. Each patient had at least two electrocardiograms taken (at the beginning and at the end of the disease). In the course of the work, a new method for measuring the area of the teeth P, T, QRS complex and ST-T segment was developed and described using the dynamic mathematical program GeoGebra Classic 6.0 by correlating the millimeter grids of the electrocardiogram and the program and further constructing an irregular shape taking into account the polarity of the teeth and segments. According to the study, the sum of the ST-T segment areas in all 12 leads is statistically significantly greater at the end of the disease in individuals over 30 years old. It is also significantly higher in the right thoracic leads (V1-V2) in for all ages. Probably, these changes are associated with the severity of the underlying disease and, consequently, with the overload of the right parts of the heart.

Master regulators associated with poor prognosis in glioblastoma multiforme
Authors: Kalya M.P. , Beisbarth T. , Kel A.
Published: June 2021

Glioblastoma multiforme (GBM) is a highly malignant brain tumor with average survival time of 15 months. Less than 2% of the patients survive beyond 36 months. To understand the molecular mechanism responsible for poor prognosis, we analyzed GBM samples of TCGA microarray (n=560) data. We have identified 720 genes that have a significant impact upon survival based on univariate cox regression. We applied the Genome Enhancer pipeline to analyze potential mechanisms of regulation of activity of these genes and to build gene regulatory networks. We identified 12 transcription factors enriched in the promoters of these genes including the key molecule of GBM – STAT3. We found that STAT3 had significant differential expression across extreme survivor groups (short-term survivors– survival 36 months) and also had a significant impact on survival. In the next step, we identified master regulators in the signal transduction network that regulate the activity of these transcription factors. Master regulators are filtered based on their differential expression across extreme survivors groups and impact on survival. This work validates our earlier report on master regulators IGFBP2, PDGFA, OSMR, and AEBP1 driving short survival. Additionally, we propose CD14, CD44, DUSP6, GRB10, IL1RAP, FGFR3, and POSTN as master regulators driving poor survival. These master regulators are proposed as promising therapeutic targets to counter poor prognosis in GBM. Finally, the algorithm has prioritized several drugs for the further study as potential remedies to conquer the aggressive forms of GBM and to extend survival of the patients.

: A series of an acute atypical respiratory disease occurred during December 2019 in Wuhan, China, that quickly metamorphosed as a pandemic, spreading across the globe, leaving more than 104,911,186 infected and more than 2,278,579 dead, in its wake within a year. This Novel Coronavirus, was also called Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and the disease was called Coronavirus Disease 19 (COVID-19). On 30 January 2020, The World Health Organisation (WHO) Director-General, declared the novel coronavirus outbreak, a public health emergency of international concern and flagged off WHO's highest level of alarm.

: To elaborate the various drug therapies used in trials and vaccines available for COVID-19 across the globe.

: We compiled the literature searches under a single heading and scrutinized over 154 articles, for extracting data on the various pharmacotherapeutic approaches available to treat COVID-19.

: Despite wide and varied treatment guidelines being available, the cure or prevention is still elusive for COVID-19. The categoric efficacy of vaccines must be proved to tackle the fast-mutating coronavirus.

: Current medical management is largely supportive with no targeted therapy available. Several drugs including lopinavir-ritonavir, remdesivir, antibiotics, hydroxychloroquine, steroids, anticoagulants, and antidiabetic drugs like metformin have been tried in clinical trials. Vaccines targeting the three different components of SARS-CoV-2 viruses, in different phases of clinical trials world-wide, have been made available.

: We need drugs to decrease inflammation as well as have very less side effects. Review of literature mentioned anti-inflammatory action of Omega 3 fatty acids. Hence, we selected this drug.

Our aim was to find the anti-inflammatory effect of Omega 3 fatty acid using animal model.

: The study is objective animal study where measurement of inflammation was done by observational methodology, for the present study four groups were made- 6 Guinea pigs in each group. Control guinea pigs were fed distilled water, second group standard drug indomethacin 4mg/ kg body wt, test group 1 received 1200mg/kg body wt, test group II received 2400mg/kg body wt of Omega 3 fatty acid. All drugs given orally 30 minutes before exposure to UV radiation of 30 seconds duration was given and inflammation was observed at 6, 12 and 24 hrs after UV exposure in the form of scoring.

Statistical significance was calculated using Anova method. For statistical analysis we have used SPSS system version 20.

Inflammation was observed in all the four groups of Guinea pigs, there was significant anti-inflammatory effect of omega 3 fatty acid in the dose of 1200mg/kg body wt and 2400mg/kg body wt at 12 and 24 hours.

Omega 3 fatty acids 1200mg/kg body wt orally produced significant anti-inflammatory effect against UV radiation induced inflammation in Guinea pigs at 12 and 24 hrs. However, standard drug could produce significant anti-inflammatory effect only at 24 hrs in comparison to control group. The anti-inflammatory effects of test 1, test 2 groups and standard group are comparable.

Moral Distress Among Consumer Health Information Professionals: An Exploratory Study
Authors: O'Hanlon Robin , Angell Katelyn , Walsh Samantha
Published: June 2021

Objectives – In recent years, moral distress has become a topic of interest among health professionals. Moral distress is most commonly described in the nursing literature, and refers to a situation wherein an individual knows the correct action to take, but is constrained from doing so. While moral distress differs from the classic ethical dilemma, in recent years practitioners and theorists have advocated for a broadening of the definition of moral distress. To date, no study has examined another group of individuals who frequently interact with patients and who may be constrained by the confines of their role - Consumer Health Information Professionals (CHIPS). The objective of this study was to determine if CHIPS experience moral distress and/or ethical dilemmas, and to determine what, if any, coping strategies these individuals have developed.
Methods – This study employed a mixed methods approach. Quantitative data were gathered via an online survey which was distributed to relevant consumer health information professional electronic mail lists. The survey contained demographic questions and a series of questions related to potential discomfort within the context of work as a consumer health information professional. Qualitative data were also gathered through phone interviews with CHIPS. Interview questions included the participant’s definition of moral distress, professional experiences with moral distress, and any coping strategies to manage said distress.
Results – The authors received 213 survey responses. To test whether any of our demographic variables help to explain survey response, we used STATA to calculate Pearson correlation coefficients. Individuals who were more likely to experience discomfort in their occupation as CHIPS included individuals with less experience and individuals who identified as Black and Latinx. Interview data indicated that participants most commonly experienced ethical dilemmas related to censorship, providing prognosis information, and feeling constrained by institutional policies. Few interview participants described scenarios that reflected moral distress.
Conclusions – CHIPS do not appear to experience moral distress, at least according to its most narrow definition. CHIPS do consistently experience distinct ethical dilemmas, and the most durable patterns of this phenomenon appear to be related to experience level and racial identity. In recent years, researchers have raised calls to broaden the definition of moral distress from its narrow focus on constraint to include uncertainty, and CHIPs do experience moral uncertainty in their work. Further study is needed to determine how to best address the impacts of discomfort caused by ethical dilemmas among these groups.
Problems of sustainable development and challenges related to production

Published: June 2021

Due to the changes taking place in the environment of enterprises, many problems arise in their strategic and operational activities. The basis of the emerging problems is primarily the overproduction associated with short product life cycles. It contributes to the excessive use of various types of natural resources, often in a predatory manner. On the one hand, such an approach increases waste, and on the other, contributes to the destructive degradation of the environment. The result is a lack of food and water in some countries, climate change and related extreme weather phenomena, as well as various types of disasters, such as pandemics, fires, floods, droughts, etc. Water, air and land pollution as well as global warming are reflected in deteriorating quality of life. Despite many threats, more and more enterprises perceive the danger and undertake various types of adaptive projects. It should also be emphasized that the environmental awareness of both micro-enterprises and large corporations is growing. The purpose of this chapter is to introduce the reader to the basic problems that companies may encounter in their operations activity. First, changes in the environment are discussed, with particular emphasis on the depletion of natural resources, pollution of a destructive nature, as well as waste and its causes. The next part deals with the topic of globalization, pointing to both positive and negative aspects. Technical progress and related aspects such as new technologies, new processes and materials are discussed in the next part. In this part, particular attention is paid to improving productivity, thanks to the implementation of new technical solutions. Technical progress is directly related to the innovations presented in the next section. This section describes the types of innovation according to various criteria as well as factors that are conducive to increments in the level of innovation in the enterprise. The last part is devoted to the most important factor in operational activity—human esources. Competences, qualifications and the importance of human resources in the production process were discussed.

Authors: Aguilar-Carpio Cid , González Maza Sergio V. , Juarez-Lopez Porfirio , Alia-Tejacal Irán , Palemón-Alberto Francisco , Arenas-Julio Yasmani R. , Escalante-Estrada Alberto S.
Published: June 2021

El epazote (Chenopodium ambrosioides L.) se utiliza como alimento, condimento y medicinal. La información sobre el manejo de la nutricional para la producción de epazote es insuficiente, por lo que, el objetivo del estudio fue evaluar el efecto de tres concentraciones de la solución nutritiva Steiner sobre el crecimiento de epazote cultivado en invernadero. El estudio se realizó en Cuernavaca, Morelos, México. El genotipo utilizado fue H-1000 (Hortaflor®). Se aplicaron tres concentraciones (50, 75 y 100 %) de la solución nutritiva Steiner para evaluar el crecimiento del cultivo mediante muestreos destructivos a los 39, 46, 53, 60, 67 y 74 días después de la siembra; en cada muestreo se midió y calculó el área foliar, índice de área foliar, peso fresco, materia seca, tasas de crecimiento del cultivo y absoluta de crecimiento. A las variables se les realizó un análisis de regresión con el programa Excel®. En general, con la concentración de la solución nutritiva a 100 % se obtuvieron los mejores resultados en las variables evaluadas, en comparación a la concentración 75 y 50 %. La mayor altura, área foliar, materia seca, tasa de crecimiento del cultivo y peso fresco se obtuvieron con la solución nutritiva Steiner a 100 %.
„Spokojnie, jestem grzeczny”. Molestowanie seksualne jako strategia uczestników badania
Authors: Palęcka Alicja
Published: June 2021

Celem artykułu jest uwidocznienie przemocy doświadczanej w terenie przez badaczki i badaczy. Po pierwsze, przemoc bywa częścią pracy w terenie i jako taka może podlegać analizie. Po drugie, przemilczanie jej wzmacnia szkodliwe aspekty kultury akademickiej, w której problemy związane z przynależnością do grup mniejszościowych (w tym problemy kobiet w akademii) pozostają niewidoczne. W konsekwencji instytucje badawcze nie wypracowują mechanizmów wsparcia dla osób doświadczających przemocy, a badacze i badaczki nie są przygotowane na tego rodzaju trudności. Analizuję trzy przypadki molestowania seksualnego, którego doświadczyłam w terenie. Interpretuję je jako jedną ze strategii przyjmowanych przez uczestników badań podczas wywiadu dla zyskania władzy lub kontroli nad sytuacją.
Lucha contra el Narcotráfico en América Latina-Caribe. La Labor de la Organización de Estados Americanos (OEA)
Authors: Jiménez Francisco
Published: June 2021

En el Resumen Ejecutivo del Informe Mundial sobre las Drogas de 2020, elaborado por la Oficina de las Naciones Unidas contra la Droga y el Delito (UNODC, en sus siglas inglesas), se hacen importantes reflexiones sobre el panorama internacional en la lucha contra el tráfico ilícito de drogas. En primer lugar, se resalta que esta cuestión sigue siendo una responsabilidad compartida que exige un enfoque internacional concertado en los países de origen, tránsito y destino, pues, pese a la aparición de sustancias psicoactivas inorgánicas, la mayor parte de la demanda de las sustancias con que se trafica sigue estando en los países en los que no se producen las drogas, y la mayor parte de los ingresos se generan en los países de destino. Por otra parte, se constata que si bien en el actual contexto mundial, el problema de la lucha contra las drogas y su fiscalización nunca ha tenido una vertiente tan internacional, sin embargo, su eficacia apenas se mide a nivel mundial. Cuando se ha pedido a los Estados partes en los tratados internacionales que evalúen la cooperación internacional, “las respuestas se han mantenido constantes pese a la evolución del mercado internacional de las drogas, de lo que se desprende que es necesario crear instrumentos mejores para seguir los progresos en materia de cooperación internacional a lo largo del tiempo, a fin de evaluar con más rigor las enseñanzas extraídas y los obstáculos que a la larga podrían entorpecer la cooperación y restarle eficacia” (pp. 12-13).
