An Experimental Study on the Dynamic Behavior of an Ultra High-Strength Concrete

Ultra-high-strength concrete is a newly developed construction material that has a minimum 120 MPa or higher compressive strength. Recently, the usage of high-strength and ultra-high-strength concretes has become widespread due to the enhancement of the concrete technology. Many civil engineering structures constructed by using concrete materials are usually subjected to, in addition to static loads, dynamic loads due to earthquakes, wind and storm, impact and blast, which take place under high energy and high strain rate values. The effects of such loadings on the structure must be understood thoroughly. In recent years, the withstanding of a structure on these loading conditions has become a crucial issue for its impact on the economy and human safety. One of the approaches to fulfill these requirements is to develop high-strength or ultra high-strength concretes (UHSCs). In this study, an ultra-high-strength concrete with a compressive strength of 135 MPa was designed and developed. In order to determine the dynamic behavior of this UHSC, the specimens at three height/diameter ratios (approximately, 0.6, 1.0 and 1.2) were extracted from the prepared concrete mixtures. These concrete specimens were tested to determine both the quasi-static and dynamic compressive behaviors of the developed concrete. In the quasi-static compression tests, cylindrical specimens and a conventional compressive testing machine were used. In order to study the dynamic compressive behavior, a Split Hopkinson Pressure Bar (SHPB) test setup was used. In this test system, the time variations of compressive strength, the strain and strain rates under uniaxial pressure loading were experimentally evaluated and the deformation and fracturing processes of the specimens were recorded using a high-speed camera. The test results, based on the testing of 21 different specimens, have shown that the dynamic compressive strength values of the developed concrete varied in the range of 143 to 253 MPa, while the strain rate values varied in the range of 353 s−1 to 1288 s−1. Using the data generated in the SHPB tests, the parameters present in a Johnson–Holmquist–Cook concrete material model, which is used in numerical studies on the high strain rate behavior of concretes, were evaluated.
Experimental Trends in Corruption and Tax Evasion

espanolEntre las principales preocupaciones de la sociedad espanola, encontramos la corrupcion y el fraude, que ocupan el segundo lugar en terminos de relevancia segun datos recientes. Los enfoques neoclasicos tradicionales se fundamentan en la construccion de modelos economicos que intentan explicar las causas de ambos fenomenos. Sin embargo, en la ultima decada han surgido varios estudios centrados en un enfoque comportamental para mejorar la capacidad explicativa de dichos modelos. En este sentido, se han implementado experimentos economicos para estudiar, desde una perspectiva diferente, los determinantes de la corrupcion, por un lado, y del fraude fiscal, por el otro. No obstante, pocos estudios empiricos relacionan ambos problemas sociales, especialmente cuando nos referimos a la evasion fiscal de agentes economicos individuales. Por ello, el objetivo de este articulo es revisar y profundizar en la comprension de los factores que determinan y relacionan la evasion fiscal y la corrupcion, desde el enfoque experimental. EnglishNowadays, among the main social concerns of the Spanish society we find corruption and fraud, which occupy the second place in terms of relevance according to recent data. The traditional neoclassical economic approaches concentrate on the construction of economic models that aim to explain the causes of both social phenomena. However, in the last decade several studies have emerged focusing on a behavioral approach to improve the explanatory capacity of such models. In this sense, economic experiments have been implemented to examine, from a different perspective, the determinants of corruption, on the one hand, and fiscal fraud, on the other. Few empirical studies relate both social problems, especially when we refer to the tax evasion of individual economic agents. Therefore, this paper aims to review and deepen the understanding of the factors that determine and relate tax evasion and corruption, from an experimental approach.
The Effect of Otoprotective Substances Against Cisplatin Exposure: A Literature Review

The Effect of Otoprotective Substances Cisplatin Abstract Introduction: Progressive and irreversible hearing loss is the most frequent side effect in patients using platinum therapy for head and neck malignancies. Previous studies on cisplatin-induced ototoxicity have shown that accumulation of reactive oxygen species leads to oxidative stress and subsequent intracellular reactions, eventually leading to cell-death. The aim of this study is to review recent evidence about the use of different substances and their otoprotective effect in humans or animals exposed to cisplatin therapy. Methods: Scientific databases such as PubMed and Cochrane were thoroughly searched from 14/04/20 to 02/05/20, based on the next audition side of cisplatin ototoxicity, against cisplatin. We include clinical trials, randomized controlled trials, reviews and systematic reviews published in English over the last five years. Results and Discussion: Many substances have been used to experience their protective use in cisplatin exposure, but the minority have shown a positive effect in humans such as sodium thiosulfate and N-acetylcysteine, some others are in the experimental phase in animals or in in-vivo phase and others have not shown favorable results at all. Conclusion: Cisplatin has been reported to be a substance that can cause an important otoacoustic damage, but it is essential in the treatment of different types of cancer, so the benefit is worth the risk, but in order to avoid the ototoxic damage, otoprotective substances should be prescribed before and during the administration of cisplatin.

Novel aroA of Glyphosate-Tolerant Bacterium Pseudomonas sp. Strain HA-09 Isolated from Roundup-Contaminated Garden Soils in Iran

Background: Glyphosate is a non-selective systemic herbicide with a broad spectrum of weed control that inhibits a key enzyme, 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase, in the shikimate pathway. Objectives: Isolation and analysis of the epsps (aroA) gene responsible for glyphosate-tolerance in bacteria from Roundup- contaminated soils was the aim of this study. Materials and Methods: Sampling was done from the soil of the gardens which were heavily contaminated by Roundup herbicide and then bacterial screening was performed in the presence of high concentrations of glyphosate. The genus of bacterium was identified via molecular methods such as 16S rRNA sequencing. The aroA gene of this bacterium (aroAHA-09) was isolated using the primers designed-upon specific regions of aroA genes available in NCBI GenBank database. The PCR product was cloned, sequenced and subcloned into pET28a as an expression vector and transferred into E. coli strain BL21(DE3). The cells were inoculated in liquid M9 minimal medium containing IPTG and different concentrations of glyphosate. Results: The genus of bacterium was identified as Pseudomonas sp. strain HA-09. The isolated aroAHA-09 gene from this bacterium was approximately 2.2 kb in size. Bioassay of E. coli expressing this gene showed high tolerance to glyphosate (up to 300 mM). Conclusion: The aroAHA-09 gene could be considered as a novel and efficient candidate for development of glyphosate-tolerant crop plants.
Synergistic Hepatoprotective Interaction between α-Tocopherol and Ascorbic Acid on Paracetamol Induced Liver Damage in Rats

Background and objectives: The hepatoprotective activity of vitamin E and C is evident due to their ability of modulating the antioxidant pathway. In this study, we have evaluated the effects of α-tocopherol and ascorbic acid on paracetamol induced liver damage with offsetting various levels of drug treatment following an in vivo experimental protocol on Wistar albino male rats. Materials and Methods: The level of lipid peroxidation as well as histological examination of liver tissues were observed among 50 Wistar albino male rats to evaluate hepatoprotective effect of α-tocopherol and ascorbic acid on hepatocytes. The experiment was divided into 5 groups (10 rats in each group)Basal control group (Group-I, with propylene glycol), Paracetamol treated control group (Group –II), α-tocopherol pretreated & paracetamol treated group (Group –III), Ascorbic acid pretreated & paracetamol treated group (Group –IV) and Ascorbic acid pretreated & paracetamol treated group (Group –IV). Results: The mean (± SD) Malondialdehyde (MDA) concentration were significantly reduced in α-tocopherol pretreated and paracetamol treated group (P<0.001), Ascorbic acid pretreated and paracetamol treated group (P≤0.05) and combined α-tocopherol with ascorbic acid pretreated & paracetamol treated group (P<0.001). Statistically significant differences in histological findings of rat liver were observed in paracetamol treated control group (P<0.001), ascorbic acid pretreated and paracetamol treated group (P<0.001). The serum alanine aminotransferase (ALT) level was also significantly higher in paracetamol treated group (P<0.001), αtocopherol pretreated plus paracetamol treated group (P≤0.05) and in ascorbic acid pretreated plus paracetamol treated group (P<0.001). Conclusion: The combined pretreatment of α-tocopherol & ascorbic acid have better hepatoprotective effects than α-tocopherol or ascorbic acid alone against paracetamol induced liver damage. The decrement of free radicals produced by vitamin E could be a better hepatoprotective antioxidant than vitamin C in paracetamol induced toxicity.
Power to the people? Populism, democracy, and political participation: a citizen's perspective

Abstract Much research is devoted to the relationship between populist parties and democracy. However, relatively little is known about the relationship between citizens’ populist attitudes and democracy. This article examines the relationship between populist attitudes, support for democracy, and political participation (voting, protest, support for referendums, and support for deliberative forms of participation). Using survey data from the Netherlands, this article shows that individuals with stronger populist attitudes are more supportive of democracy, are less likely to protest, are more supportive of referendums, and are more supportive of deliberative forms of political participation compared to individuals with weaker populist attitudes. Results show no relationship between populist attitudes and voting. These findings provide important insights into the relationship between populism, democracy, and political participation from a citizen’s perspective.
Redescription of Leposternon octostegum (Duméril, 1851), with an identification key for Brazilian Leposternon species, remarks on meristic methodology, and a proposal for pholidosis nomenclature (Squamata: Amphisbaenidae)

The amphisbaenian Leposternon octostegum (Duméril, 1851) is redescribed based on newly collected material from the state of Bahia, Brazil. Species validity was confirmed, and comparisons made to other Leposternon species and to the scarce literature available on Leposternon octostegum taxonomy. Aspects of meristic annuli methodology are reviewed, and nomenclatural adjustments for some scales are proposed. To place this information in its taxonomic context, a species identification key for the Brazilian species of the genus Leposternon is provided. The present redescription contributes to a better understanding of Amphisbaenia taxonomy, thus also enabling the design of more adequate conservation and management strategies for the species belonging to this group.

The Influence of Discrimination and Coping Style on Blood Pressure Among Black/African American Women in the InterGEN Study

Purpose: Although research has explored the effects of racism on mental health, few studies have investigated the effects of racism on physical health. In this study, we examined the influence of racial discrimination and race-related stress and coping on blood pressure within a cohort of Black/African American women. Methods: This was a secondary data analysis of 226 Black/African American women from the Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure study. Experiences of racial discrimination and coping, measured by the Experiences of Discrimination scale and the Race-Related Events Scale, were analyzed in relation to systolic blood pressure (SBP) and diastolic blood pressure (DBP). Multiple linear regression was used to explore the interaction effect of coping and discrimination on blood pressure for both scales. Results: Age and elevated body mass index were associated with increased SBP and DBP, and low income was associated with increased DBP. Among individuals who reported no personal experience of discrimination, more active coping strategies were associated with higher DBP. There was no evidence of a relationship between type of coping strategies used and blood pressure among individuals who did report experiences of discrimination. Conclusion: Differences in coping strategy in response to racism were not found to have a significant moderating effect on DBP in Black/African American women.
Insight into the binding of ACE-inhibitory peptides to angiotensin-converting enzyme: a molecular simulation

ABSTRACT Angiotensin-I-converting enzyme (EC 3.4.15.1; ACE) plays an important physiological role in the regulation of blood pressure by converting angiotensin I to angiotensin II, a potent vasoconstrictor. Therefore, ACE inhibition has become a major target control for hypertension. Pipefish, or hailong, is an essential traditional Chinese medicine that is widely used in anti-fatigue and anti-cancer. A recent study has found two ACE-inhibitory peptides (TFPHGP and HWTTQR) purified from the seaweed pipefish by Alcalase enzymatic hydrolysis. Two peptides exhibited different ACE-inhibitory activities; however, the molecular mechanism involved is poorly understood. Further investigations are necessary to elucidate the relationship between the inhibition mechanism and the peptides. The current study is focused on investigating the interactions between each ACE-inhibitory peptide and ACE by performing molecular docking and molecular dynamics (MD) simulations. ACE protein remained stable throughout the simulations. Furthermore, ACE-TFPHGP complex showed lower binding energy as compared to ACE-HWTTQR complex, which is in good agreement with the experimental results. Glu384 and Glu411 of ACE are key residues upon the ACE-inhibitory peptides binding. Molecular basis generated by this attempt could provide valuable information towards designing new medicine for ACE inhibitor.
Inactivity stochastic precedence order

Abstract The aim of this article is to extend the inactivity probability order, defined by Abouelmagd et al. (Communications in Statistics-Theory and Methods 47, 3293–3304, 2018), to the case of non independent random variables. It is done by defining a new stochastic order based on the inactivity times of two non negative dependent random variables and the stochastic precedence order. Some characterizations and preservation properties of the new stochastic order have been developed. Also, some of its reliability properties and its relation with the other existing well known stochastic orders have been studied. We also discuss some applications of the derived results.
Isolation, characterization and efficacy of lytic bacteriophages against pathogenic Escherichia coli from hospital liquid waste

Lingga R, Budiarti S, Rusmana I, Wahyu AT. 2020. Isolation, characterization and efficacy of lytic bacteriophages against pathogenic Escherichia coli from hospital liquid waste. Biodiversitas 21: 3234-3241. Escherichia coli is known as a pathogenic contaminant bacteria in hospital wastewater hazardous to humans and the environment. Concerns about the emergence of chlorineand antibiotic-resistant bacteria increase the urgency to find an alternative strategy to control pathogenic bacteria in hospital wastewater . One of the alternatives is using lytic bacteriophage. This study aimed to isolate, characterize, and examine the efficacy of lytic bacteriophage against pathogenic Escherichia coli from hospital wastewater. It isolated, characterized (plaque morphology, host range, virion electron micrograph, and sensitivity to temperature, pH, and chlorine treatments), and tested the efficacy of lytic bacteriophages in controlling pathogenic E. coli isolated from hospital wastewater. Five phages were successfully obtained, all of which had clear plaques (lytic phage character). Based on host range assay, most of the phages could lyse all tested E. coli strains but not for other species. Electron micrograph photography revealed that the phages belonged to Myoviridae. The phages showed stability in high temperature, broad-ranged pH, and high concentrations of chlorine treatments. Assay on phages efficacy suggested that the phages are capable of significantly reducing the E. coli population both in sterilized and non-sterilized wastewater. The combination of phage treatment and chlorine was more effective than single phage treatment. The efficacy test revealed that phage application in wastewater had the best result seen from cocktail treatment and a combination of phage treatment and chlorine. These results suggested that the phage can be a potential candidate for disinfection purposes.
Ecological and economical sustainability assessment of community forest management in Nepal: A reality check

ABSTRACT This study analyzes the sustainability of community forest management, representing four forest types of two physiographic region Hills and Terai of Nepal. We assess the sustainability based on species composition, stand density, growing stock volume, and growth-to-removal ratio using inventory data of 109 permanent forest plots from four consecutive intervals of three to five years. In addition, forest users, forest committee members, and forest officials were consulted. We observed increment on the representation of economically valuable tree species in all forest types of both regions. The pole-size tree dominates in all forest types with declining number of trees and regeneration. In case of Hills forests, they were over-harvested until 2013 but were under-harvested in the recent period. In contrary, forests were under-harvested in the Terai. We found that ecological objectives of sustainable management are fully achieved while economic benefits remained unharnessed where harvesting is far below the growth. We conclude that maintaining a large number of trees may contribute to ecological but not on economical sustainability. We argue to rationalize annual harvest in all categories of the forest to enhance resource conditions together with regular benefits to the local communities.
Genetic Diversity Among Accessions of Cucurbita pepo Resistant to Phytophthora Crown Rot

Phytophthora capsici Leonian, the causal agent of Phytophthora crown rot in squash (Cucurbita pepo L.), is an economically important pathogen worldwide. Currently, no C. pepo cultivars immune to the pathogen are commercially available, but sources of resistance to Phytophthora crown rot have been identified in a set of 16 C. pepo plant introductions (PIs). Knowledge of the genetic relationships among these accessions and their relatedness to economically important morphotypes of C. pepo would inform breeders’ best strategies for introgressing resistance; however, this information is currently lacking. The goal of the current study was to determine genetic diversity among the resistant accessions and their genetic relatedness to susceptible morphotypes of subspecies pepo (Zucchini and Pumpkin) and texana (Acorn, Straightneck, and Crookneck) using 39 SSR markers. The markers revealed 132 alleles averaging 4.40 alleles per locus and had a mean polymorphic information content (PIC) and gene diversity of 0.44 and 0.49, respectively. CMTp235 had the highest PIC and gene diversity of 0.80 and 0.82, respectively. Hierarchical clustering by UPGMA and principal coordinate analysis (PCOA) revealed grouping into two major C. pepo subspecies, texana and pepo, with all the resistant accessions grouping in the latter. In order of increasing genetic distance (GD), the resistant accessions were least distant to Zucchini (GD = 0.34), followed by Pumpkin (GD = 0.40), Crookneck (GD = 0.56), Acorn (GD = 0.60), and Straightneck (GD = 0.61) morphotypes. Mean GD among the resistant accessions was 0.31 and was highest between PIs 615142 and 615132 (0.61). Based on genetic similarity, PIs 174185 and 181761 (disease severity ≤1.4) would be the best sources of resistance for transfer into subspecies texana and pepo, respectively. Overall, the results presented here support a closer genetic relationship between the resistant accessions and morphotypes of subspecies pepo than those of subspecies texana.
