Authors: Singh Dharamveer , Yenare Chetan , Showkat Burhan 
Published: June 2020

Abstract
Increase in the asphalt binder prices, dwindling crude oil resources, and an enhanced obligation for environmentally sustainable asphalt binder necessitates the exploration of alternate avenues. One such promising approach is the adoption of bio-oil (BO) from biomasses for the production of asphalt binder. This study adopts BO derived from groundnut shell biomass (by fast pyrolysis) for modification of AC30. BO was incorporated in AC30 at varying dosages of 5, 10, and 15 % by weight. The tests performed included carbon, hydrogen, nitrogen, sulfur, and oxygen; Fourier transform infrared (FTIR) spectroscopy; absolute viscosity; softening point; dynamic viscosity; frequency sweep at multiple temperatures; performance grade (PG); multiple stress creep and recovery; and linear amplitude sweep. Both carbon, hydrogen, nitrogen, sulfur, and oxygen and FTIR analysis indicated that BO had caused alterations at the molecular level of AC30. An increase in absolute viscosity and softening point was observed up to a BO dosage of 10 %. Dynamic viscosity was observed to increase until 5 % BO dosage. BO dosages of 10 % and 15 % were observed to increase the high-temperature PG. However, the intermediate temperature grade increased for all BO dosages. Only 15 % BO dosage caused a compromise in the low-temperature PG. Nonrecoverable creep compliance was observed to decrease until the BO dosage of 10 %, indicating an enhancement in rutting resistance. Also, fatigue life was observed to enhance until 10 % BO dosage. Overall, the study indicated that groundnut shell BO can substantially improve the resistance to primary distresses of rutting, fatigue, and thermal cracking. Conclusively, a BO dosage of 10 % was observed to be the most favorable.
Effect of Re-vibration on Strength Properties of Lightweight Concrete
Authors: Kassim Muayad Mohammed 
Published: June 2020

Abstract
In relatively deep structural members, re-vibration is applied to sequential layers after they are initially hardened. This may cause harmful effects on strength properties, especially on lightweight concrete (LWC). In this experimental study, the effects of re-vibration on LWC properties were thoroughly investigated. Local lightweight crushed pumice rock named “Bonza,” as well as set retarding admixture and silica fume (SF) were used to produce four different mixes of LWC. These mixes were re-vibrated at different time lags (0:00, 2:50, 4:30, and 5:30 [h:min]). After the re-vibration process, compressive and tensile strength properties, as well as pulse velocity, density, and permeable voids volume of hardened concrete mixes, were investigated. Results showed that using the setting retarder and partial SF replacement of Portland cement, the density, compressive, and tensile strength properties were increased in all re-vibrated mixes when the re-vibration was accomplished before the final set time of the cement. A lack of correlation between ultrasonic pulse velocity, density, and compressive strength was also detected. Furthermore, a linear relationship was found between permeable voids volume and compressive strength of all mixtures.
Visualization of Localized Deformations of Sand in Drained Triaxial Compression Using Digital Image Correlation

Published: June 2020

Abstract
The deformation behavior of sand in drained triaxial compression has been investigated using three-dimensional digital imaging correlation (3D DIC) based on surface deformation data for a deforming cylindrical specimen of sand. 3D DIC was utilized to obtain very detailed quantitative surface deformations, and strains were interpreted using large strain formulation. The time at which localization occurs as well as the characteristics of localization, whether it be bulging or shear banding, is greatly influenced by the initial relative density and less by particle morphology for a given effective confining stress. This paper summarizes important experimental observations related to strain localizations that were observed consistently for rounded and angular specimens for varying initial void ratios and confining stresses as a function of particle morphology. Data suggest similar pre-peak localization profiles irrespective of particle morphology. The post-peak evolution of localization is influenced by particle shape.

Published: June 2020

Desde o final de 2019, na China, um novo coronavírus passou a provocar síndrome respiratória aguda grave (SARS) que se espalhou pelo mundo e estabeleceu uma pandemia. O surto já acometeu milhões de pessoas, gerou centenas de milhares de mortes e trouxe prejuízo econômico que pode alcançar trilhões de dólares. Vírus como o agente da COVID-19 passam a infectar o homem por episódios de salto da barreira interespecífica, passando por uma ou mais espécies. Assim, a contaminação inicial depende do contato com a vida selvagem, o que se torna cada vez mais comum com a hiperexploração de espécies, a destruição de habitats e o aumento populacional. O estudo desse fluxo de agentes infecciosos, relacionando a medicina humana à sanidade animal e às questões ambientais é feito pela Medicina da Conservação. A partir de pesquisa exploratória, analisou-se a COVID-19 através da perspectiva médico-conservacionais e mostrou-se que intervenções na origem dos agentes infecciosos seriam capazes de restringir surtos devastadores de doenças e, consequentemente, reduzir impactos sociais e econômicos.

Published: June 2020

AbstractReproductive isolation is central to speciation, but interspecific crosses between two closely related species can produce viable and fertile hybrids. Two different species of tunicates in the same ascidian genus, Ciona robusta and Ciona intestinalis, can produce hybrids. However, wild sympatric populations display limited gene flow, suggesting the existence of obstacles to interspecific reproduction that remain unknown. Here, we took advantage of a closed culture system to cross C. robusta with C. intestinalis and established F1 and F2 hybrids. We monitored post-embryonic development, survival, and sexual maturation to characterize the genetic basis of simple traits, and further probe the physiological mechanisms underlying reproductive isolation. Partial viability of first and second generation hybrids suggested that both pre- and postzygotic mechanisms contributed to genomic incompatibilities in hybrids. We observed asymmetric fitness, whereby the C. intestinalis maternal lines fared more poorly in our system, pointing to maternal origins of species-specific sensitivity. We discuss the possibility that asymmetrical second generation inviability and infertility emerge from interspecific incompatibilities between the nuclear and mitochondrial genomes, or other maternal effect genes. This work paves the way to quantitative genetic approaches to study the mechanisms underlying genomic incompatibilities and other complex traits in the genome-enabled Ciona model.

Abstract
Hybrid sterility is a hallmark of speciation, but the underlying molecular mechanisms remain poorly understood. Here, we report that speciation may regularly proceed through a stage at which gene flow is completely interrupted, but hybrid sterility occurs only in male hybrids whereas female hybrids reproduce asexually. We analyzed gametogenic pathways in hybrids between the fish species Cobitis elongatoides and C. taenia, and revealed that male hybrids were sterile owing to extensive asynapsis and crossover reduction among heterospecific chromosomal pairs in their gametes, which was subsequently followed by apoptosis. We found that polyploidization allowed pairing between homologous chromosomes and therefore partially rescued the bivalent formation and crossover rates in triploid hybrid males. However, it was not sufficient to overcome sterility. In contrast, both diploid and triploid hybrid females exhibited premeiotic genome endoreplication, thereby ensuring proper bivalent formation between identical chromosomal copies. This endoreplication ultimately restored female fertility but it simultaneously resulted in the obligate production of clonal gametes, preventing any interspecific gene flow. In conclusion, we demonstrate that the emergence of asexuality can remedy hybrid sterility in a sex-specific manner and contributes to the speciation process.
Caenorhabditis elegans AF4/FMR2 Family Homolog affl-2 Regulates Heat-Shock-Induced Gene Expression

Abstract
To mitigate the deleterious effects of temperature increases on cellular organization and proteotoxicity, organisms have developed mechanisms to respond to heat stress. In eukaryotes, HSF1 is the master regulator of the heat shock transcriptional response, but the heat shock response pathway is not yet fully understood. From a forward genetic screen for suppressors of heat-shock-induced gene expression in Caenorhabditis elegans, we found a new allele of hsf-1 that alters its DNA-binding domain, and we found three additional alleles of sup-45, a previously molecularly uncharacterized genetic locus. We identified sup-45 as one of the two hitherto unknown C. elegans orthologs of the human AF4/FMR2 family proteins, which are involved in regulation of transcriptional elongation rate. We thus renamed sup-45 as affl-2 (AF4/FMR2-Like). Through RNA-seq, we demonstrated that affl-2 mutants are deficient in heat-shock-induced transcription. Additionally, affl-2 mutants have herniated intestines, while worms lacking its sole paralog (affl-1) appear wild type. AFFL-2 is a broadly expressed nuclear protein, and nuclear localization of AFFL-2 is necessary for its role in heat shock response. affl-2 and its paralog are not essential for proper HSF-1 expression and localization after heat shock, which suggests that affl-2 may function downstream of, or parallel to, hsf-1. Our characterization of affl-2 provides insights into the regulation of heat-shock-induced gene expression to protect against heat stress.

La consejería nutricional evidencia un proceso comunicacional, interpersonal y participativo entre el nutricionista y el paciente. Estudios previos demuestran que esta intervención tiene efecto en el cambio de dieta, niveles de lípidos y presión arterial. Así, la nutrición pasó de brindar intervenciones desde un enfoque preventivo, a una perspectiva terapéutica en el caso de patologías crónicas, lo que facilita tomar decisiones nutricionales que mejoren el control glicémico, presión arterial, colesterol total (CT) y el índice de masa corporal (IMC).

Aim. Evaluation of the effectiveness and identification of the benefits of a video-assisted fistula treatment method using fistuloscopy, in comparison with traditional methods of surgical treatment of complex forms of chronic paraproctitis, trans- and extrasphincteric, relapsing rectal fistulas. Patients and methods. A complex analysis of the results of surgical treatment was carried out in 228 patients with chronic paraproctitis, transphincteric, ectrasphincteric, including recurrent rectal fistulas, divided into three groups (main and two control), depending on the surgical methods of chronic paraproctitis used. Results. The result of surgical treatment of pararectal fistulas in the three study groups was compared. The effectiveness of treatment was assessed by the results of immediate and long-term postoperative period. It has been established that the use of a video-assisted fistula treatment method using fistuloscopy excludes the presence of an extensive postoperative wound in the perianal region, which significantly reduces the likelihood of its secondary infection, and the sphincter trauma, and in fact virtually eliminates its insufficiency. The use of video-assisted method of treatment of fistulas made it possible to reduce the number of postoperative complications. Conclusion. The final results (92.7% of favorable outcomes) allow us to recommend a video-assisted treatment for fistulas for wide practical implementation.

Published: June 2020

There are some reasons that appeal me to do research on contemporary linguists’ contributions to Sībawaih’s al-Kitâb. As a pioneer on Arabic linguistics book, al-Kitâb has been the starting point for the classic linguists to study linguistics phenomena. And so are the contemporary linguists. For the later, they place the book in the first raw of references, be it by taking instant benefits from the fundamentals it contains or by keen reading on it. In fact, some efforts conducted by the linguists after Sībawaih can be regarded to as attempts to comprehend his theories, as well as to explain aspects which are still ambiguous to some others. This is what can be understood from the abundance varieties of works produced by later linguists: they criticize the book; they give commentaries, they give preliminary fundaments on further readings on it; they study on the theories; they explain the sources; and they trigger to study the construct of Sībawaih’s thoughts. From these various studies, even if they refer to the same book (al-Kitâb), it can be grasped that the linguist do not meet an agreement one and others in comprehending Sībawaih’s words. In this piece of paper, I try to describe what contemporary linguists do with the al-Kitāb, and how the link it to their theories. After all, this can be regarded as their contributions to the book in developing linguistics theories in a wider context.

Sexual Health Programs for Latinx Adolescents: A Meta-analysis
Authors: Evans Reina , Widman Laura , Stokes McKenzie , Javidi Hannah , Hope Elan , Brasileiro Julia 
Published: June 2020

CONTEXT:
Latinx adolescents are at risk for negative sexual health outcomes, and many interventions have been developed to reduce this risk.

OBJECTIVE:
In this meta-analysis, we synthesized the literature on sexual health interventions for Latinx adolescents and examined intervention effects on 3 behavioral outcomes (abstinence, condom use, number of sex partners) and 3 psychological outcomes (safer sex knowledge, intentions, self-efficacy). Moderators of intervention success were explored.

DATA SOURCES:
A systematic search of studies published through January 2019 was conducted by using PubMed, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature databases.

STUDY SELECTION:
All studies included a US-based sample of Latinx adolescents, evaluated sexual health intervention by using an experimental or quasiexperimental design, included a behavioral outcome, and were in English.

DATA EXTRACTION:
Standardized mean difference (d) and 95% confidence intervals (CIs) were meta-analyzed by using random-effects models.

RESULTS:
Effect sizes from 12 studies, sampling 4673 adolescents, were synthesized. Sexual health interventions improved abstinence (d = 0.15, 95% CI: 0.02 to 0.28), condom use (d = 0.44, 95% CI: 0.18 to 0.70), number of sex partners (d = −0.19, 95% CI: −0.37 to −0.001), and sexual health knowledge (d = 0.40, 95% CI: 0.10 to 0.70), compared with control conditions. Effects were consistent across a number of demographic and clinical characteristics, although culturally tailored interventions produced greater change in condom use than nontailored interventions.

LIMITATIONS:
There was variation across studies in measures of sexual behavior, and some elements of individual study quality were unclear.

CONCLUSIONS:
Sexual health interventions have a small but significant impact on improving safer sexual behavior among Latinx adolescents. Health educators should consider the importance of cultural tailoring to program success.
