Authors: Qadir Warzer , Ghafor Kawan , Mohammed Ahmed 
Published: October 2019

AbstractIn this study, the effect of lime content (L %) on the plastic properties such as water-cement ratio (w/c), setting times, flowability, compressive, flexural and bond strengths of cement mortar were investigated. Based on the information in the literature the amount of lime varied between 0 to 45% (by weight of cement). The experimental results were compared with the data collected from different research studies and quantified using two different models. The plastic and hardened properties of the cement mortar modified with different percentage of lime were conducted according to the ASTM and BS standards. Based on the literature data the water to cement ratio (w/c) ranged between 0.3-0.74 percent, the w/c of 0.5 was selected in this study. The compressive and flexural strengths of cement mortar modified with lime up to 28 days of curing were ranged between 3 MPa to 65 MPa and 2 MPa to 12 MPa respectively. The compressive, flexural and bond strengths of the cement mortar decreased with increasing lime content. Vipulanandan correlation model was used to correlate the relationship between lime with consistency, setting times, flowability and compressive strength of cement mortar. Compressive and flexural strengths of cement mortar modified with lime were quantified very well as a function of w/c, lime content and curing time using nonlinear relationship.

Does an association exist between socio-economic status and subjective physical, mental and social well-being among early adolescents?
Authors: Steinvoord Katrin , Junge Astrid 
Published: October 2019

Abstract

Background
It is well known that the socio-economic status (SES) has a great impact on adult and childhood well-being. Comparatively little research has been conducted on the relationship of adolescents’ subjective well-being to SES. Recent studies though, display a tendency for a strong relationship between adolescences’ subjective physical, mental and social well-being to SES. We therefore wanted to find out whether an association exists between SES and subjective physical, mental and social well-being among adolescents as well as between SES and individual school marks.

Methods
The cross-sectional data of 450 German adolescent students (average age 11 years old) were analysed. The data included socio-demographic variables, school marks and selected subscales of three well-established questionnaires [KIDSCREEN, Kid-Kindl® and the German version of the Strengths and Difficulties Questionnaire (SDQ-deu)]. The Hamburg Social School Index (HSSI) was used as an indicator of SES.

Results
Significant differences between SES and physical (T = −2.04; p < 0.05) as well as social well-being (‘Social Support and Peers’ with T = −2.04; p < 0.05) of adolescents were found. Generally, no relations between SES and mental well-being were found. School marks also differed between low and high school SES [German (T = 3.13; p < 0.05), English (T = 5.38; p < 0.01), Mathematics (T = 3.16; p < 0.05) and Sports (T = 2.10; p < 0.05)].

Conclusion
As health in adolescence is a predictor for health in adulthood, health promotion and prevention need to start early (primary school) to improve physical and social well-being in low SES families and schools.

Authors: Khan Zeeshan , Tairan Nasser , Mashwani Wali Khan , Rasheed Haroon Ur , Shah Habib , Khan Waris 
Published: October 2019

Abstract
The present paper related to thin film flows of two immiscible third grade fluids past a vertical moving belt with slip conditions in the presence of uniform magnetic field. Immiscible fluids we mean superposed fluids of different densities and viscosities. The basic governing equations of continuity, momentum and energy are incorporated. The modeled coupled equations are solved analytically by using Adomian Decomposition Method (ADM) along with Homotopy Analysis Method (HAM). The residual errors show the authentication of the present work. For comparison, numerical method (ND-Solve) is also applied and good agreement is found. The effects of model parameters on velocity, skin friction and temperature variation have been studied. At the end, the present study is also compared with single layer flow and revealed in close agreement with the result available in the literature.
Synthesis and properties of isotopes of the transactinides
Authors: Hofmann Sigurd 
Published: October 2019

Abstract
Isotopes of transactinide elements have to be synthesized in nuclear reactions with light or heavy beam particles. The efficient production by neutron capture and subsequent β
− decay as it is used for the production of isotopes of actinide elements up to fermium is no longer possible due to the lack of suitable target material. The content of this article is about the synthesis and the study of the decay properties of nuclei to which atomic, respectively proton numbers from Z = 104 to 118 could be unambiguously assigned by physical means. The results identified the reaction products as isotopes of new elements beyond the actinides, the transactinides. As such the elements received names given by the discovers ranging from rutherfordium for element 104 to oganesson for element 118 which completes the 7th row of the Periodic Table of the Elements. Intensive heavy ion beams, sophisticated target technology, efficient electromagnetic ion separators, and sensitive detector arrays were the prerequisites for discovery of the elements from Z = 107 to 118 during the years from 1981 to 2013. The results and the techniques are described. Also given is a historical introduction into early experiments and the theoretical predictions for a possible existence of an island of stability located at the crossing of the next closed shells for the protons and neutrons beyond the doubly magic nucleus 208Pb. The experimental results are compared with recent theoretical calculations on cross-sections and decay modes of these superheavy nuclei, respectively isotopes of superheavy elements. An outlook is given on further improvement of experimental facilities which will be needed for exploration of the extension and structure of the island of superheavy nuclei, in particular for searching for isotopes with longer half-lives predicted to be located in the south east and for isotopes of further new elements expected in the north-east direction of the island at the upper end of the chart of nuclei.
The Static-Dynamic Efficiency Trade-off in the US Rail Freight Industry: Assessment of an Open Access Policy
Authors: Coublucq Daniel , Ivaldi Marc , McCullough Gerard 
Published: October 2019

Abstract
Considering the US railroad industry, which is characterized by seven integrated firms that provide freight services on tracks they own and maintain, this paper provides a structural model that allows to evaluate the potential effects of opening the rail network to new firms on prices and investment incentives. In particular, we propose a framework for analyzing the tension between static efficiency (pricing behavior) and dynamic efficiency (investment behavior). The investment behavior is rendered endogenous by means of a dynamic model where the current investment depends on the expected future profits. We then use a forward simulation procedure to analyze the effect of an open-access market structure where a new firm uses the network of one of the biggest railroad firm. Under a simple access charge equaled to the marginal cost of access, investment in network infrastructure decreases by 10% per year, leading to a significant decrease in network quality over time. Under this setting, despite the increase of price competition, the decrease in network quality leads to a fall in consumer welfare. Other types of (more evolved) access charges might even allow to relax the tension between static efficiency and dynamic efficiency, allowing more price competition while preserving investment incentives. This topic deserves further research and is beyond the scope of this paper.
Proposal for a New Quantum Theory of Gravity III: Equations for Quantum Gravity, and the Origin of Spontaneous Localisation
Authors: Palemkota Maithresh , Singh Tejinder P. 
Published: October 2019

Abstract
We present a new, falsifiable quantum theory of gravity, which we name non-commutative matter-gravity. The commutative limit of the theory is classical general relativity. In the first two papers of this series, we have introduced the concept of an atom of space-time-matter (STM), which is described by the spectral action in non-commutative geometry, corresponding to a classical theory of gravity. We used the Connes time parameter, along with the spectral action, to incorporate gravity into trace dynamics. We then derived the spectral equation of motion for the gravity part of the STM atom, which turns out to be the Dirac equation on a non-commutative space. In the present work, we propose how to include the matter (fermionic) part and give a simple action principle for the STM atom. This leads to the equations for a quantum theory of gravity, and also to an explanation for the origin of spontaneous localisation from quantum gravity. We use spontaneous localisation to arrive at the action for classical general relativity (including matter source) from the action for STM atoms.
High-temperature superconductors: underlying physics and applications
Authors: Bussmann-Holder Annette , Keller Hugo 
Published: October 2019

Abstract
Superconductivity was discovered in 1911 by Kamerlingh Onnes and Holst in mercury at the temperature of liquid helium (4.2 K). It took almost 50 years until in 1957 a microscopic theory of superconductivity, the so-called BCS theory, was developed. Since the discovery a number of superconducting materials were found with transition temperatures up to 23 K. A breakthrough in the field happened in 1986 when Bednorz and Müller discovered a new class of superconductors, the so-called cuprate high-temperature superconductors with transition temperatures as high as 135 K. This surprising discovery initiated new efforts with respect to fundamental physics, material science, and technological applications. In this brief review the basic physics of the conventional low-temperature superconductors as well as of the high-temperature superconductors are presented with a brief introduction to applications exemplified from high-power to low-power electronic devices. Finally, a short outlook and future challenges are presented, finished with possible imaginations for applications of room-temperature superconductivity.

Authors: Babaliche Prakash , Menon Ankita 
Published: October 2019

Background : Advanced novel therapies and antiretroviral medications for the treatment of human immunodeficiency virus (HIV) infection have led to the improved management and survival of the infected patients. However, I [i]t manifestations in late-stage diseases such as cardiac deformities, which are the major cause of fatality in HIV-infected patients. Hence the current study was undertaken to derive the association of cardiac dysfunctions in HIV-infected patients using electrocardiograph (ECG)and echocardiography (ECHO).Methodology : The study included a total of 100 consecutive patients with HIV infection and was performed during January–December 2016 in the Department of General Medicine. Prior to the commencement of the study, ethical clearance was obtained from the Institutional Ethical Committee. Patients underwent complete blood count, ECG, and ECHO. Data were analyzed using Microsoft Excel spreadsheet and R-3.4.1 software.Results : Majority of the patients were males (79) and 40–49 years was the most common age group. The duration of HIV infection in most of the patients (73) was 1–10 years. Among the study population, 79 patients received antiretroviral drugs. Chi-square test was used to find the association of clinical symptoms and cardiac abnormalities with CD4 count. Cardiac manifestations were observed in 62% patients; sinus tachycardia (29%) was found to be the most common cardiac manifestation on ECG. Diastolic and systolic dysfunctions were observed in 35 patients and 49 patients, respectively.Conclusion : Patients with HIV infection are at a higher risk of developing cardiac dysfunctions. Early identification through ECG and ECHO-revealed abnormalities might assist in cardiac-targeted interventions, which can significantly reduce the fatal outcomes in HIV-infected patients.

Published: October 2019

Hypothesis/aims of study. Currently, preeclampsia is one of the most pressing problems of obstetrics due to the complexity of pathogenesis and to the lack of early and reliable diagnostic criteria. The preeclampsia rate in patients with bronchial asthma is proved higher than in asthma free pregnant women. This study aimed to establish the prediction algorithm of preeclampsia development in in pregnant women suffering from bronchial asthma of varying severity and different level of control.
Study design, materials and methods. Asthma duration was studied in 110 pregnant women using the SPSS Discriminant Function Analysis method. Basic therapy and level of asthma control were studied together with respiratory tests, obstetrician medical history, and complications of the first and second trimesters of pregnancy. In addition, serum interleukin panel was assessed and placental Doppler measurement was carried out.
Results. Clinical and statistical analysis made it possible out of 87 significant risk factors for the development of hypertensive disorders and preeclampsia to form a highly informative set of signs for a linear discriminant model for predicting preeclampsia: 1) asthma exacerbation in the first trimester of pregnancy; 2) asthma duration severity; 3) average dose of inhaled glucocorticosteroid drugs administered to the exact patient during pregnancy; 4) serum levels of tumor necrosis factor, interferon gamma, and interleukins-4, 6, and 8.
Conclusion. The inclusion method of step-by-step discriminant analysis allowed establishing a highly informative four-component complex of clinical predictors for preeclampsia development in pregnant women with asthma. The results of the model testing showed its extremely high reliability (up to 100% within study selection as well as within control selection). Thus, the study results can be recommended for clinical use.

Background: In the Russian Federation, newborn screening comprises thyroid stimulating hormone determination to exclude primary congenital hypothyroidism. Screening is carried out throughout Russia. Neonatal TSH can be used to assess iodine deficiency and monitor iodine prevention programs.Objective: To assess and compare official statistical data on congenital hypothyroidism, the prevalence of hypothyroidism and iodine deficiency syndrome in children, as well as urinary iodine in the Russian regions.Materials and methods: The level of neonatal TSH was determined in 97.69% of children born in the Russian Federation in 2017. This article represents the results on the prevalence of hypothyroidism in the regions with various iodine availability. The correlation analysis was used to assess the relationship of CH incidence in newborns and iodine availability.Results: The calculated correlation coefficient, which was 0.2, reflects a weak relationship between the degree of iodine deficiency in the region and the number of newborns diagnosed with congenital hypothyroidism.Conclusions: In the Russian Federation, a law on universal salt iodization does not exist, and many regions are still in conditions of moderate or severe iodine deficiency. To assess the iodine status in these particular regions, we could use the results of newborn TSH screening

Objective: to evaluate the innovative organizational, medical and pharmacoepidemiological approaches for the prevention of circulatory system diseases in pre-primary care using mobile health technologies.Materials and methods: 3,694 people went through preventive consultation (questionnaires, anthropometry, body fat and blood pressure evaluation, electrocardiography, glucose and blood cholesterol) at equipped medical sites in shopping centers and rural health posts.Results. Among the surveyed, there were both healthy people and patients cardiovascular diseases and diabetes mellitus. Behavioral (insufficient consumption of fruits and vegetables, adding more salt without trying food, physical inactivity, smoking and alcohol abuse) and nutritional (obesity, hypertension, hypercholesterolemia and glycaemia) risk factors of chronic noncommunicable diseases were detected that contribute to high mortality from circulatory system diseases in the Tver region. This is associated with low adherence to drug therapy and its lack of efficacy in patients with hypertension, ischemic heart disease and cerebrovascular diseases.Conclusion: to assess the effectiveness of CSD prevention in pre-primary care, it is possible to use mobile medical sites in shopping centers and rural health posts.
