About Synergistic Effect of Lubricant and Chemical Additives on Obtaining Quality Surface of Concrete Products
Authors: Yukhnevskiy P. I. , Dimitriadi N. P. 
Published: August 2019

The paper substantiates scientific background for development of lubricant compositions used in moulds for concrete products with high-quality surface. It has been shown that consideration of interaction between air bubbles, lubricant and liquid phase of modified concrete is of great importance. A release agent must allow air to migrate to a certain extent and leave “formwork – concrete mix” interface. In this regard the lubricant must have low viscosity. In addition, the lubricant should give maximum hydrophobization to a mould and have minimal adhesion in respect of the concrete mix. Additives of hydrophobic substances in liquid lubricants significantly reduce surface porosity of products. Chemical plasticizing additives and, in particular, additives of polycarboxylate type substantially reduce surface tension of liquid sгж, thereby they significantly reduce work for fixing an air bubble on concrete surface and contribute to its ejection. In addition, adsorbed molecules of the chemical additives interfere with interaction of cement paste particles and mould surface. Polycarboxylate additive molecules diffuse from a diffuse layer of the concrete mix, fill capillaries in the lubricant film, reduce its viscosity, act as additives that regulate spreading of lubricant and facilitate removal of air bubbles in a surface layer. Experimental studies of the combined effect while using low viscosity grease based on vegetable oils and modifying additives have confirmed the above provisions. The polycarboxylate-based additive has made the greatest impact on reduction of concrete surface porosity and content of all types of pores in the concrete has been approximately at the same level.

Published: August 2019

The paper presents a complex of laboratory and theoretical studies of physical and mechanical properties in centrifuged concrete while using samples of sectoral cross-section which are cut in layers from a finished product. A post made of concrete having B40 grade for compression strength and manufactured while using centrifugation with the help of РТЦ-5 machine. Assessment of heterogeneity across section thickness has been carried out by visual determination of composition changes in cross section, determination of strength, density of the obtained concrete samples, and water content over cross section of concrete mix. According to the results of a visual study on composition of a concrete structure it has been revealed that 1/8 part of the structure (from an inner surface) does not have a large aggregate. Later, as it moves to periphery, there is an increase in coarse aggregate and a decrease in size and number of cells between grains of gravel. An analysis of experimental data has shown that properties of the centrifuged concrete in samples being sawn in layers change significantly: density of concrete in samples of an inner layer is lower by 8 % than in samples of an outer layer, and compressive strength of concrete – by 34 %, water content of concrete mixture of samples of the inner layer has turned out to be by 43 % higher than in samples of the outer layer. Approximating curves showing regularities of changes in density, concrete strength, water content of concrete mixture over thickness have been constructed in the paper. Linear and exponential equations have been obtained that describe changes in physical and mechanical properties of centrifuged concrete over section depending on structure properties as a whole, which, taking into account the obtained correction factors k1 and k2, can be used with an acceptable level of confidence in practical calculations of centrifuged concrete structures. Relationship between strength of centrifuged concrete varying over cross section and action of a centrifugal force of inertia has been revealed in the paper. An equation has been obtained that relates the strength of centrifuged concrete to its density. Analysis of the research results makes it possible to assert that the main source of loading perception in centrifuged concrete structures is outer layers.

Published: August 2019

The paper presents results of research aimed at developing a new semi-functional concrete additive that provides an increase in rate and level of its strength growth while reducing energy costs to accelerate hardening process, as a basis for reducing energy intensity in manufacturing of concrete and reinforced concrete products and structures. Experimentally a rational ratio of components for a polyfunctional additive has been found of mass cement: a superplasticizer based on polycarboxylate resins (for example, “Stachement 2000” or “Relamiks PC”) – 0.5 %, ultradispersed microsilica (SiO2) – 1.0 %, sodium sulfate (Na2SO4), hardening accelerator – 0.5 %, aluminum sulfate (Al2(SO4)3), sealing additive structure ‒ 0.25 %. The mentioned components ensure the largest increase in strength of cement stone and structural heavy concrete. Results of derivatographic and X-ray phase analyses have shown that strength growth is based on formation of a fine-crystalline form of low-base crystalline silicates of CSH-silicate group, which complements traditionally formed C2SH by the reaction of threeand two-calcium silicate cement with water, as well as it is based on an increase in the number of neoplasms due to the reaction of Ca(OH)2 with amorphous SiO2 and ettringite 3CaO × Al2O3 × 3CaSO4 × 32H2O, being formed due to reactions with cement aluminates these are accelerating-compacting additive components, that in total provides an increase in density and strength of cement stone. While having the case with concrete, the effect is complemented by hardening the zone of contact between aggregate surface and cement stone due to the reaction between Ca(OH)2 and SiO2. These effects have been confirmed by growth (up to 38 %) of water which is chemically bound with cement in presence of a multifunctional additive in samples of cement stone, which is characterized by the largest strength. While using standardized testing methods, effectiveness of a multifunctional additive has been experimentally confirmed and it has been expressed in growth of quality characteristics and properties of structural heavy concrete: compressive strength – up to 40–60 %, flexural strength – up to 15 %, reduction of shrinkage – up to 50 % and water absorption – by 1.5–2 times, increase in frost resistance from brand F250 to F500, water resistance – from W6–W8 to W20.

Published: August 2019

Abstract
Background

The 2013–2015 Ebola Virus Disease (EVD) outbreak in Guinea resulted in community mistrust that influenced health care service utilization. This study aimed to assess whether EVD-related memories affect post-outbreak health-seeking behaviours for children under five years of age with febrile illnesses in Guéckédou district, Guinea.

Methods

This cross-sectional study was conducted by interviewing caregivers of children under five years of age in the sub-district most affected by the EVD outbreak (Guèndembou) and the least affected sub-district (Bolodou) in Guéckédou district. Memories of the outbreak were referred to as EVD-related fears in the post-EVD period, which was based on a series of questions regarding current feelings.

Results

While the majority of caregivers sought care for their children with febrile illness in both districts, a statistically significantly higher proportion of caregivers in Guèndembou sought care, compared to caregivers in Bolodou. Though not statistically significant, caregivers with a fear score above the median and those who reported the death of family members or friends due to EVD were more likely to seek care.

Conclusions

This study found that the presence of EVD memories is likely to have a positive influence on health-seeking behaviour in the rural district of Guéckédou. However, the findings call for more efforts to preserve communities’ key values and address the psychosocial effects of EVD in rural Guinea.

Abstract
Background: In the absence of strict regulations, the extent of exposure to Bisphenol A (BPA) toxicity depends mainly on the consumers’ own knowledge, attitude, and practices about the matter. The aim of this study was to assess the current level of familiarity and knowledge about BPA, attitude towards it, practices related to the use of BPA-containing products, and the predictors of each.
Methods : We carried out a cross-sectional study among students at the American University of Beirut, Lebanon, between January and April 2017. Full-time students above the age of 18 and registered in a specific major were eligible to participate in the study. An English questionnaire that assesses familiarity, as well as knowledge, attitude, and practice (KAP) was developed based on current literature and expert opinion. Demographics, lifestyle, and level of familiarity with the topic were assessed among all participants. Predictors of familiarity, defined as knowing at least a little about BPA, were assessed among all participants using bivariate and multivariate analyses. Among students familiar with BPA, predictors of higher KAP scores were assessed by similar analyses. Adjusted odds ratios (OR) with 95% confidence interval (CI) were reported.
Results : The level of familiarity with BPA was 23.7%. Studying in a health-related field was a predictor of familiarity (adjusted OR=3.11; CI: 2.08-4.66). Among those familiar with BPA, a higher study level predicted better knowledge (adjusted OR=3.03; CI: 1.33-6.89) and better practices to avoid BPA (adjusted OR=2.53; CI: 1.08-5.97). Additionally, a higher family income was a predictor of higher knowledge and better practice, with an adjusted OR of 2.82 (CI: 1.12-7.08), and 2.9 (CI: 0.99-8.56), respectively. Father education was also a predictor of safer practices with an adjusted OR of 2.58 (CI: 1.01-6.56). Furthermore, female gender was the only predictor of higher attitudes towards BPA and its potential health effect (adjusted OR=2.19; CI: 1.08-4.46).
Conclusion : Familiarity with BPA among university students in Lebanon is low. Future research is needed to determine the level of familiarity, knowledge, attitude, and practice among the general Lebanese population. Awareness campaigns and policy change are needed to ensure lower exposure to BPA.

Abstract
Background

Prevalence of smoking is on the rise and its harmful effects on every organ of body are well known. Smoking is a growing concern due to adverse effects on health, its association with academic performance is not well studied.

Objectives

This study aims to assess the prevalence of smoking among undergraduate students of age 18-24 years in a public sector university of Islamabad, association between smoking and academic performance and also to assess the reasons of smoking initiation among undergraduate students.

Methods

The study included 500 undergraduate students. A self-report structured questionnaire was used to assess smoking, dietary habits, physical activity, parent’s smoking, friend’s smoking, time spent on mobile and TV and academic performance for collection of data. Logistic regression was used for association between smoking and academic performance.

Results

Results of study show that 112/500 (22.4%) students were smokers among them 93/112 (34.6%) were males and 19/112 (8.2%) were females. The mean age of study participants was 21.50 years (SD: 1.72. Prevalence of smoking was higher in students belonging to rural areas 23.5% to that of urban areas 21.9%. Three major reasons of smoking initiation; 25% students stated peers and friends, 21% stated easy availability while 14% said it was fun and enjoyment they started smoking. High academic performance was found to be inversely proportional to student’s smoking; at p-value 0.000 smokers had 2.5 (1.77, 3.74) odds of lower academic performance, boys having 2.17 (1.56, 3.03) odds of lower academic performance in last semester exams.

Conclusion

Findings highlighted extensive cigarette smoking among undergraduate students of Islamabad. Smoking is significantly and negatively associated with academic performance.

Published: August 2019

Abstract
Background: This study aimed to explore whether autophagy can attenuate postoperative cognitive dysfunction (POCD) by up-regulating cystatin C in aged rats undergoing splenectomy.
Methods: Rats were randomized into four groups (n = 10 per group): normal control (CON), surgery (SUR), surgery + rapamycin (autophagy inducer) at 1.0 mg/kg/d (RAP), and surgery + 3-methyladenine (autophagy inhibitor) at 3.0 mg/kg/d (3-MA). Treatments were carried out for four weeks. Learning and memory were assessed postoperatively using the Morris water maze. Hippocampal expression of the autophagy-related proteins ATG5, LC-3B, Beclin1, and p62 as well as Cys C was assayed using Western blotting and real-time polymerase chain reaction.
Results: SUR animals showed higher levels of autophagy and higher expression of autophagy proteins and Cys C than CON animals. These levels were even higher in RAP animals, which also showed lower levels of the inflammatory cytokines IL-1β, IL-6 and TNF-α than the other groups. Learning and memory functions were higher in RAP animals than in the other groups on days 5 and 7. Effects of 3-MA were opposite to those of RAP.
Conclusion: Autophagy improves learning and memory in aged rats following splenectomy, which may involve up-regulation of Cys C and attenuation of neuroinflammation.

Published: August 2019

Abstract
Background

This study aimed to investigate the predictive value of JNK pathway-associated phosphatase (JKAP) level for severe acute pancreatitis (SAP) risk, and its association with disease severity, inflammation and in-hospital mortality in SAP patients.

Methods

Our study recruited 50 SAP patients, 50 moderate-severe acute pancreatitis (MSAP) patients, 50 mild acute pancreatitis (MAP) patients and 50 healthy controls. And the serum samples were obtained from all acute pancreatitis patients within 24 hours after admission and from health controls at their enrollment to detect JKAP level by enzyme-linked immunosorbent assay.

Results

JKAP level was decreased in SAP patients compared with healthy controls, MSAP and MAP patients. And receiver operating characteristics (ROC) curve analysis revealed that JKAP could not only distinguish SAP patients from healthy controls (AUC: 0.914, 95%CI: 0.857-0.971), but also differentiate SAP patients from MAP patients (AUC: 0.869, 95%CI: 0.802-0.937) and MSAP patients (AUC: 0.712, 95%CI: 0.610-0.813). In SAP patients, JKAP was negatively correlated with Ranson score, acute physiology and chronic health care evaluation II (APACEH II) score, sequential organ failure assessment (SOFA) score and C-reactive protein (CRP). And lower JKAP level, higher CRP level, Ranson score, APACEH II score and SOFA score were associated with increased in-hospital mortality in SAP patients. Additionally, ROC curve analysis showed that JKAP could predict decreased in-hospital mortality in SAP patients (AUC: 0.720, 95%CI: 0.526-0.914).

Conclusions

JKAP might serve as a biomarker for disease risk and management for SAP.

Abstract
Objectif The aim of this study was to investigate psychiatric comorbidities (depression and anxiety) associated with acne in dermatology in Lomé (Togo). Material and methods We conducted a case-control study between July 2017 and February 2018. Each case was matched to two controls by sex and age (± 5 years). The ECLA grid was used for the clinical evaluation of acne, and the GAD-7 and PHQ-9 questionnaires were used for respective screening of anxiety and depression. Results We recruited, with their consent, 900 subjects including 300 patients and 600 matched to two controls according to sex and age (± 5 years). The mean age of the cases was 23.7±5.7 years and that of the controls was 23.6 ± 6.2 years, with no difference between the two groups (p = 0.9362). The overall severity score for acne according to the ECLA grid ranged from 2 to 28 points. The severity of acne was not correlated with anxiety scores (GAD-7: r = -0.02; p = 0.6724) and depression (PHQ-9: r = 0.11; p = 0.0567). The GAD-7 questionnaire allowed us to note 72 cases of anxiety (24%) among our patients and 37 cases among our controls (6.2%). The mean GAD-7 score in the cases was 6.5±4.9 compared with 2.9±3.8 in the controls (p <0.0001). Similarly, the PHQ-9 questionnaire allowed us to detect 92 cases of depression (30.7%) among our patients and 82 cases of depression among our controls (13.7%). The average of the PHQ 9 score in the cases was 7.2 ± 5.2 versus 4.0 ± 4.7 in the controls (p <0.0001). Conclusion: Depression and anxiety are significantly associated with acne, regardless of severity. It is important to look for them in any patient admitted for acne, for a psychological / psychiatric decision.

Published: August 2019

Abstract
Background: The aim of this study was to explore the expression pattern and prognostic value of MMP-28 for bladder cancer and analyze its relationship with the clinicopathological features of human bladder cancer.
Methods: Immunohistochemical staining for MMP28 was performed in 491 archived radical bladder cancer resection and 80 normal specimens. The immunoreactivity of these proteins was correlated to evaluate their clinical significance as prognostic factors.
Results: Protein level of MMP-28 was up-regulated in bladder cancer compared with adjacent non-tumor tissues. The increased expression of MMP-28 was significantly associated with high histological grade, lymph node metastasis, lymphatic invasion and distant metastasis (P<0.05). High expression of MMP-28 was also associated with greater risk of disease progression and decreased chance of cancer-specific survival. Further analysis suggested that MMP-28 was related with decreased overall survival.
Conclusions: MMP-28 could be used as an effective marker for tumor diagnosis and predict tumor progression in bladder cancer. The expression patterns of MMP-28 interaction correlated well with the pathological stage, disease progression and tumor-specific survival. The finding may help identify more biologically aggressive carcinomas which could aid in patients who benefit from more intensive adjuvant therapy.
