Abstract
The effect of gamma radiation on CR-39 detector was determinate through the image processing for the photoelasticity images by using of MATLAB software. The maximum change different in CR-39 detector colors at photoelasticity technique was appear at the value 2 kN as a mechanical compression effect. It was adopted this value of mechanical compression on CR-39 detector to calculation the change in color percentage -C% for four colors red, green, magenta and yellow. It was found the increase of gamma irradiation dose -D(Gy) on CR-39 detector at the range (100 to 600 Gy) lead to change in color percentage - C% for four colors. The polynomial equation for red color was a good smooth relation compared with polynomial equations for green, magenta, where the yellow color behavior as a logarithmic relation. The red color relation used to determination the effect of gamma radiation on CR-39 detector due to the clear behavior between D(Gy) with C%. In this study, we can consider that the image processing for the photoelasticity images of CR-39 detector by using of MATLAB software was a good method to calculate the effect of gamma radiation on CR-39 detector compared with other methods in this field.

Authors: Boi Huyen Nguyen Thuc , Thang Nguyen Hoc 
Published: August 2020

Abstract
Anthocyanin content reaches high value in hot extraction conditions of Ipomoea Batatas at 60°C, using a mixture of ethanol: water at ratio of 4:1. The sizes of the material had significantly affected the anthocyanin content in Ipomoea Batatas solution. The colour of the anthocyanin-rich extracted solution varied significantly in range of pH from 1-12. So, anthocyanin was used as a colour indicator. Qualitative method by colorimetric showed that the colour of anthocyanin extracted solution was very little change during the 30-day survey period (without preservatives). However, quantitative analysis by UV-Vis, with a maximum wavelength of λmax = 523 nm, shows that the absorbance of anthocyanin decreased markedly with time of storage. Experimental results showed that the storage environment also influences anthocyanin colour and uptake in Ipomoea Batatas extracted solution.

Published: August 2020

Abstract
The paper scrutinizes the main methods, applied practically, for correcting the consumption of the components considering their fullness in the technological extrusion process. The method, chosen as the basic one, includes the following: the common fullness of the components, getting into the mixer, is subtracted from the common consumption of the filler. A mathematical model for determining the values of the components for setting the dosing devices is designed. For the operational control of the filler’s components content we determined the dependencies of these values correction on the period of the filler content evaluation and transport delay of the components supply. The algorithm of the method for controlling the extrusion mixture components’ consumption, considering the content of the filler in it, is made.

Published: August 2020

Abstract
The current state of the problem of the use in aviation of new laminated aluminum glass-reinforced plastics (Glare) is given in this review. It is shown that Glares are characterized by low density (2.4 g / cm3), high strength (> 600 MPa), but at the same time they are inferior to aluminum alloys by the elastic modulus (<60 GPa).Methods for evaluating Glares service characteristics are considered, it is indicated that replacing traditional aluminum alloys in Glares with lithium alloys that have unique elastic properties can significantly improve their service characteristics.

Authors: Kovalev M , Alekseeva E , Shaposhnikov N 
Published: August 2020

Abstract
Anti-corrosion coatings are commonly used in the oil and gas industry to protect the inner surface of pipelines. Most of coatings have a polymer base and can effectively prevent the negative impact of the transported fluid. Existing standards allow to evaluate the quality of coatings and their durability in the anticipated operating conditions. The evaluation of the abrasive resistance of coatings usually limited to comparative tests on a Taber abraser. This paper presents the results of hydroabrasive resistance study of coatings using nonstandard technique. Comparative test results of various polymer (FBE), thermally sprayed coating and silicate coatings are obtained. The ways of modifying test method are proposed.
Clinical Significance and Histologic Characterization of Histoplasma Granulomas
Authors: Demkowicz Ryan , Procop Gary W 
Published: August 2020

Abstract

Objectives
To clarify the clinical significance and degree of resolution (ie, grade) of Histoplasma granulomas in routinely reviewed surgical pathology specimens and the clinical outcomes of patients with this diagnosis, with an emphasis on those not receiving antifungal therapy.

Methods
We performed a retrospective medical record, laboratory data, and surgical pathology slide review of patients with Histoplasma granulomas following institutional review board approval.

Results
Clinical, pathologic, and laboratory data from 62 patients with Histoplasma granulomas were available for review. Of these, 1 of 19 (5%) fungal cultures, 4 of 12 (33%) fungal serologic studies, 0 of 9 Histoplasma urinary antigen tests, and 0 of 2 Histoplasma serum antigen tests were positive. All but 3 of the Histoplasma granulomas were either in the resolving (grade 2) or resolved (grade 3) stage of resolution. None of the patients, including those who did not receive antifungal therapy after the histologic diagnosis, developed progressive or disseminated histoplasmosis.

Conclusions
These findings, which are supportive of clinical guidelines, suggest that patients with old, hyalinized Histoplasma granulomas do not benefit from further laboratory studies or antifungal therapy. The proposed grading of Histoplasma granulomas informs clinicians of the stage of resolution of an excised lesion, which informs therapeutic decisions and thus is recommended.

Published: August 2020

AbstractObjectiveAttention, processing speed, executive functioning, and math difficulties are common in youth with sickle cell disease (SCD) with silent cerebral infarcts (SCI). This study investigated the cognitive underpinnings of math difficulties in children with SCD and SCI.MethodYouth (n = 68) with SCD and SCI completed measures of attention [Digit Span forward (DSF); Conners Continuous Performance Test-Third Edition/Kiddie Conners Continuous Performance Test-Second Edition (CPT-3/KCPT-2)]; working memory [Wechsler Intelligence Scales (WPPSI-IV, WISC-IV, WISC-V, WAIS-IV), Working Memory Index (WMI), Digit Span backwards (DSB)]; processing speed [WPPSI-IV, WISC-IV, WISC-V, WAIS-IV Processing Speed Index (PSI)]; math reasoning [Wechsler Individual Achievement Test-Third Edition (WIAT-III) Mathematics composite (MC)]; and math fluency [WIAT-III Math Fluency composite (MF)] as part of a clinical neuropsychological evaluation. Parent ratings of attention and executive functioning were obtained [Behavior Assessment System for Children-Third Edition (BASC-3), Behavior Rating Inventory of Executive Function (BRIEF)].ResultsMC was positively correlated with WMI (r = 0.59, p = 0.00), PSI (r = 0.40, p &lt; 0.001), DSF (r = 0.29, p = 0.03), DSB (r = 0.47, p &lt; 0.001), and MF (r = 0.71, p &lt; 0.001). Correlations between MC, sustained attention, and parent ratings were nonsignificant. The linear regression model using correlated variables was significant [F(4,51) = 8.29, R2 = 0.39, p &lt; 0.001]. WMI was the only significant variable within the model (p = 0.02).ConclusionsWorking memory deficits account for significant variance in untimed mathematical performance in this population—consistent with other populations with white matter dysfunction. Interventions targeting both mathematics and working memory may be beneficial.
Cosmeceuticals: The Principles and Practice of Skin Rejuvenation by Nonprescription Topical Therapy
Authors: Glass Graeme Ewan 
Published: August 2020

Abstract

Background
Aesthetic practice relies on a harmonious relationship between medicine and commerce. Bridging the gap is a large number of skincare products that make therapeutic claims while avoiding the regulatory framework of pharmaceuticals. In this gray area, clinicians find themselves poorly disposed to counsel patients wisely as the industry is expanding faster than empirical evidence of efficacy and safety can be acquired. To serve our patients and engage with industry, we must understand the theoretical principles and evaluate the clinical evidence in practice.

Objectives
The purpose of this paper is to classify cosmeceuticals by method of action, explain how they work in principle with reference to skin aging, and evaluate the clinical evidence for them.

Methods
A literature and cosmetic clinic website search was conducted to establish a list of the most commonly advertised cosmeceuticals, and a peer-reviewed literature search was then conducted to establish the clinical evidence for them.

Results
A huge number of cosmeceuticals are marketed for skin rejuvenation but almost invariably they fall into 1 of 4 categories. These include the induction of tissue repair mechanisms, inflammatory modulation, scavenging of reactive oxygen species, or a combination of the 3. With the exception of retinol derivatives and hydroxy acids, the clinical evidence is limited, despite promising preclinical evidence for several cosmeceuticals.

Conclusions
Cosmeceuticals reside within a highly competitive ecosystem and are often brought to market based on preclinical, not clinical evidence. Success and failure will largely be governed by the establishment of clinical evidence in retrospect.
Pareto’s Trattato di Sociologia Generale: a behaviourist ante litteram approach
Authors: Marchionatti Roberto , Mornati Fiorenzo 
Published: August 2020

Abstract
The paper deals with the changing relationship between economics and sociology in Pareto’s thought and suggests a new interpretation of this relationship. Pareto’s opus magnum in the field, the Trattato di Sociologia Generale (1916, French ed. 1917), is usually considered the result of the abandonment of economics by the late Pareto in favour of another field of interest, sociology—the realm of the analysis of non-rational actions—and on the basis of this interpretation it has been largely neglected by economists. This paper maintains that the sociology of the Trattato has to be considered not as an abandonment of interest in economics, but rather as a programme for the reconstruction and transformation of economics in a perspective that today could be called ‘behaviourist’.

Published: August 2020

Abstract
The extensive usage of social media polarity analysis claims the need for real-time analytics and runtime outcomes on dashboards. In data analytics, only 30% of the time is consumed in modeling and evaluation stages and 70% is consumed in data engineering tasks. There are lots of machine learning algorithms to achieve a desirable outcome in prediction points of view, but they lack in handling data and their transformation so-called data engineering tasks, and reducing its time remained still challenging. The contribution of this research paper is to encounter the mentioned challenges by presenting a parallelly, scalable, effective, responsive and fault-tolerant framework to perform end-to-end data analytics tasks in real-time and batch-processing manner. An experimental analysis on Twitter posts supported the claims and signifies the benefits of parallelism of data processing units. This research has highlighted the importance of processing mentioned URLs and embedded images along with post content to boost the prediction efficiency. Furthermore, this research additionally provided a comparison of naive Bayes, support vector machines, extreme gradient boosting and long short-term memory (LSTM) machine learning techniques for sentiment analysis on Twitter posts and concluded LSTM as the most effective technique in this regard.

Published: August 2020

AbstractBivalves’ physiological functions (i.e. growth, reproduction) are influenced by environmental variability that can be concomitant with trophic resource variations in terms of quality and quantity. Among the essential molecules that bivalves need to acquire from their diet to maintain physiological functions, fatty acids (FAs) such as polyunsaturated fatty acids (e.g. 20:4n-6 (arachidonic acid), 20:5n-3 (eicosapentaenoic acid) and 22:6n-3 (docosahexaenoic acid)) have been described to play a critical role. The present study examined the FA composition of gill membrane lipids of two bivalve species, Nodipecten subnodosus and Spondylus crassisquama, sampled in a coastal lagoon of the Northeastern Pacific (Ojo de Liebre, Mexico), at two contrasting locations (inner versus outer part of the lagoon) and at two different periods (February and August 2016). Spatiotemporal variations showed that FA composition of gill membrane lipids was highly correlated to FA composition of reserve lipids from digestive gland. This highlights the marked impact of the diet on FA composition of gill membranes. Interestingly, both species presented differences in the seasonal accumulations of plasmalogens and of particular FA that are not found in their diet (e.g. non-methylene interrupted FA, 22:4n-9trans, 20:1n-11), suggesting specific regulations of FA incorporation and lipid class composition in gill membranes to maintain optimal membrane function in their specific and changing environment. This study highlights the importance to characterize the spatial and temporal variability of food resources in order to apprehend the physiological consequences of environmental variability, as well as species differential regulation capacities in a changing world.

Abstract
The exponential growth of genomic/genetic data in the era of Big Data demands new solutions for making these data findable, accessible, interoperable and reusable. In this article, we present a web-based platform named Gene Expression Time-Course Research (GETc) Platform that enables the discovery and visualization of time-course gene expression data and analytical results from the NIH/NCBI-sponsored Gene Expression Omnibus (GEO). The analytical results are produced from an analytic pipeline based on the ordinary differential equation model. Furthermore, in order to extract scientific insights from these results and disseminate the scientific findings, close and efficient collaborations between domain-specific experts from biomedical and scientific fields and data scientists is required. Therefore, GETc provides several recommendation functions and tools to facilitate effective collaborations. GETc platform is a very useful tool for researchers from the biomedical genomics community to present and communicate large numbers of analysis results from GEO. It is generalizable and broadly applicable across different biomedical research areas. GETc is a user-friendly and efficient web-based platform freely accessible at http://genestudy.org/

Published: August 2020

AbstractBackgroundThis study aimed to determine whether there is a dose–response relationship between physical activity and the self-reported prevalence of kidney stone, based on a restricted cubic splines (RCS) method.MethodsThis study analyzed 8931 adults aged ≥20 years who had participated in the National Health and Nutrition Examination Survey (NHANES) during 2013–16. Kidney stones and physical activity were defined using a standard questionnaire, and metabolic equivalents (MET) were used to quantify the physical activity level. Logistic regression was used to assess the association between physical activity and the risk of kidney stones, and the dose–response relationship was explored using RCS.ResultsKidney stones were present in 10.3% of the analyzed individuals: 11.5% of males and 9.2% of females. After adjusting for potential confounders, compared with the first quartile (Q1) of MET, the odds ratios (ORs) of kidney stones for those with Q2, Q3 and Q4 of MET were 0.72 [95% confidence interval (CI)=0.59–0.87], 0.77 (95% CI = 0.63–0.93) and 0.63 (95% CI = 0.51–0.78), respectively (all P &lt; 0.01). The RCS regression showed that physical activity was related to kidney stones in a non-linear manner (P for non-linearity = 0.0100). The prevalence of kidney stones decreasing as physical activity increased, reaching a plateau for physical activity at approximately 2480 MET-min week−1 (OR = 0.75, 95% CI = 0.63–0.91).ConclusionsPhysical activity is inversely associated with the prevalence of kidney stones, and the dose–response relationship has a plateau, after which the prevalence of kidney stones does not change with the increase of physical activity.

ABSTRACTLittle is known about the detailed community composition of heterotrophic bacterioplankton in macrophyte-dominated littoral systems, where a considerable amount of dissolved organic carbon originates from aquatic macrophytes instead of phytoplankton. The aim of the present study was to reveal the effect of macrophytes on the microbial community and to elucidate their role in a macrophyte-dominated shallow soda lake, which can be characterised by a mosaic of open waters and reed marsh. Therefore, 16S rRNA gene amplicon sequencing, the most probable number method, cultivation of bacterial strains, EcoPlate and cultivation-based substrate utilisation techniques were applied. Differences in the structures of microbial communities were detected between the water and the sediment samples and between vegetated and unvegetated water samples. Planktonic bacterial communities of an inner pond and a reed-covered area showed significant similarities to each other. Woesearchaeia was the dominant archaeal taxon in the water samples, while Bathyarchaeia, ‘Marine Benthic Group D' and 'DHVEG-1’ were abundant in the sediment samples. The most probable number of heterotrophic bacteria was lower in the open water than in the reed-associated areas. The vast majority (83%) of the isolated bacterial strains from the water samples of the reed-covered area were able to grow on a medium containing reed extract as the sole source of carbon.
Mild hydrostatic-pressure (15 MPa) affects the assembly, but not the growth, of oil-degrading coastal microbial communities tested under limiting conditions (5°C, no added nutrients)
Authors: Barbato Marta , Scoma Alberto 
Published: August 2020

ABSTRACT
Hydrostatic pressures (HP) &lt;30–40 MPa are often considered mild, and their impact on petroleum biodegradation seldom considered. However, the frequent use of nutrient-rich media in lab-scale high-pressure reactors may exaggerate HP importance by resulting in a strong growth stimulation as compared to oligotrophic marine environments. Here, we tested coastal seawater microbial communities, presumably enriched in pressure-sensitive microorganisms. Limiting environmental conditions for growth were applied (i.e. low temperature [5°C], no added nutrients) and HP tested at 0.1 and 15 MPa, using crude oils from three different reservoirs. The cell number was not affected by HP contrary to the microbial community composition (based on 16S rRNA gene and 16S rRNA sequences). The most predominant genera were Zhongshania, Pseudomonas and Colwellia. The enrichment of Zhongshania was crude-oil dependent and comparable at 0.1 and 15 MPa, thus showing a piezotolerant phenotype under the present conditions; Pseudomonas’ was crude-oil dependent at 0.1 MPa but unclear at 15 MPa. Colwellia was selectively enriched in the absence of crude oil and suppressed at 15 MPa. HP shaped the assemblage of oil-degrading communities even at mild levels (i.e. 15 MPa), and should thus be considered as a fundamental factor to assess oil bioremediation along the water column.
