Effect of high temperature on SCC containing fly ash
Authors: Canbaz Mehmet , Acay Erman
Published: March 2021

The effect of high temperature on self-compacting concrete, which contains different amounts of fly ash, has been investigated. By considering the effect of concrete age and increased temperatures, the optimum fly ash-cement ratio for the optimum concrete strength is determined using experimental studies. Self-compacting concrete specimens are produced, with fly ash/cement ratios of 0%, 20% and 40%. Specimens were cured for 28, 56 and 90 days. After curing was completed, the specimens were subjected to temperatures of 20°C, 100°C, 400°C, 700°C and 900°C for three hours. After the cooling process, tests were performed to determine the unit weight, ultrasonic pulse velocity and compressive strength of the specimens. According to the experiment results, an increase in fly ash ratio causes a decrease in the compressive strength of self-compacting concrete. However, it positively contributes to self-compaction and strength loss at high temperatures. The utilization of fly ash in concrete significantly contributes to the environment and the economy. For this reason, the addition of 20% fly ash to concrete is considered to be effective.

Published: March 2021

The aim of this work is to determine if relapses can hinder the sequence of psychological recovery and to rebuild this sequence in patients with severe alcohol dependence that seek treatment. The sample was comprised of 159 patients seeking an intensive outpatient treatment of two years duration and who were subject to follow-up during four years after discharge. Patients were grouped according to the presence of relapse during follow-up, resulting in abstainers (n = 80) and relapsers (n = 79). Assessments were carried out in the following periods: baseline, at discharge, and at the second- and fourth-year follow-ups. The measurement variables were avoidance behavior, anxiety, depression, impulsivity and meaning in life (MiL). A control group (n = 74) was evaluated at the same periods as the patients. Results indicate a slower recovery in relapsers in comparison to abstainers in all psychological dimensions and periods assessed. At the second-year follow-up, the abstainers achieved similar scores in depression as the control participants, in addition to higher scores in Meaning in Life at the end of treatment. In patients with severe alcohol dependence, our data supports a sequence of recovery that could continue beyond the four years of follow-up after treatment. This sequence would begin with the avoidance of risk situations and continue with the rest of dimensions (anxiety, depression, impulsivity).

Published: March 2021

This study aims to determine the level of student acceptance of the cashless society era which is now being promoted by the Government as an effort to stop the spread of the Covid-19 virus in Indonesia. The occurrence of coronavirus transmission through physical contact or droplets makes people have to keep their distance and reduce the intensity of social interaction with other people. Therefore, public awareness is needed to reduce the use of cash transactions which are one of the means of spreading Covid-19 and switch to non-cash payments so that they can continue to carry out economic activities, which are the spearheads of human life. The method chosen by the author was qualitative as a combined research method with a phenomenological approach that was carried out directly to students about the changes that occurred during the pandemic. The results showed that the level of student acceptance of cashless payments was quite good with 85% of respondents using non-cash payments and this will continue to grow along with the provision of more modern technology and according to student interests.
Multi-episodic recrystallization and isotopic resetting of early-diagenetic dolomites in near-surface settings
Authors: Ryan Brooks H. , Kaczmarek Stephen E. , Rivers John M.
Published: March 2021

The lower Eocene Rus Formation in Qatar reflects carbonate deposition in a semirestricted to fully restricted marine setting on a shallow ramp. Petrographic, mineralogical, and geochemical evidence from three research cores show early diagenesis has extensively altered nearly every petrological attribute of these rocks despite not having been deeply buried. In southern Qatar, the lower Rus (Traina Mbr.) consists of fabric-retentive dolomite intervals that preserve mudstone, wackestone, and packstone textures that are interbedded with depositional gypsum beds. In northern Qatar, the same member is dominated by fabric-destructive planar-e dolomite, and evaporites are absent. In both northern and southern Qatar, the upper Rus (Al Khor Mbr.) is composed of fabric-retentive dolomite intervals as well as limestone intervals rich with Microcodium textures that display evidence of dedolomitization. Geochemical analysis reveals that the limestones have an average δ18Ocal of –10.73‰ VPDB and δ13Ccal of –7.84‰ VPDB, whereas average dolomite δ18Odol is significantly higher (–1.06‰ VPDB) but δ13Cdol values (–3.04‰ VPDB; range –10 to 0‰) overlap with δ13Ccal values. Additionally, δ13Cdol trends toward normal marine values with depth away from the calcite–dolomite contact in all three cores. Petrographic observations demonstrate that dolomite crystals are commonly included in calcite and partially to completely replaced by calcite in these intervals and suggests that dolomite formed before calcite in the Microcodium-bearing intervals. Furthermore, the dolomites are commonly cemented by gypsum in the Traina Mbr. in southern Qatar, suggesting that dolomitization may have also occurred before, or concurrent with, bedded gypsum formation and indicates that dolomitization occurred early. Early dolomites were subsequently replaced by Microcodium-bearing limestones at and immediately below paleo-exposure surfaces, and at greater depths recrystallized in mixed marine–meteoric fluids, producing a negative δ13Cdol signature that trends toward more positive values away from the limestone–dolomite contact. Lastly, the dolomites underwent another phase of recrystallization in either marine-dominated fluids or possibly a well-mixed aquifer setting, resulting in a near-0‰ δ18Odol signature but retaining the negative δ13C signature. These findings thus have implications for reconstructing the diagenetic history of carbonate rocks, as they suggest that early diagenesis of carbonates can be extremely complex, resulting in multiple stages of mineral replacement and isotopic exchange in meteoric and shallow marine fluids before significant burial. Furthermore, this study shows that dolomitization of a limestone does not necessarily prevent additional early diagenesis and multiple recrystallization events. Lastly, it emphasizes the importance of incorporating petrographic observations with geochemical data when interpreting the diagenetic history of carbonate rocks.

Published: March 2021

El osteoma es una lesión osteogénica benigna, derivado de hueso compacto o esponjoso. Se caracteriza por ser de crecimiento lento y aparece con más frecuencia entre los 20 y los 50 años de vida, con una prevalencia mayor en hombres con respecto a las mujeres. Clínicamente asintomáticos, los podemos encontrar en la región craneofacial, particularmente en los senos paranasales y la mandíbula, y pueden presentarse de tres formas: central, periférica y extraósea, siendo más comunes los solitarios, a diferencia de los múltiples que están relacionados con el síndrome de Gardner. El tratamiento de los osteomas es quirúrgico cuando causan complicaciones. Los estudios por imágenes, como la radiografía panorámica y la TCHC, son las modalidades de mayor uso para determinar la ubicación, la extensión y las relaciones anatómicas de la lesión. Las características imagenológicas pueden presentarse como una excrecencia ósea de hueso compacto, esponjoso o mixto. El conocimiento de esta lesión nos permitirá tener mejores propuestas diagnósticas.
Developing Upscaling Approach for Swarming Hydraulic Fractures Observed at Hydraulic Fracturing Test Site through Multiscale Simulations

Published: March 2021

This work aims to address a challenge posed by recent observations of tightly spaced hydraulic fractures in core samples from the hydraulic fracturing test site (HFTS) in the Middle Wolfcamp Formation. Many fractures in retrieved cores have subfoot spacing, which is at odds with conventional models in which usually one hydraulic fracture is initiated per cluster. Models assuming a single fracture at each cluster, although a common practice, often predict excessive fracture propagation that is inconsistent with microseismic observation. Here, we aim to develop a numerical approach to effectively account for densely spaced hydraulic fractures in field-scale simulations. Because it is impractical to explicitly model all aforementioned fractures, we develop a new upscaling law that enables existing simulation tools to predict reservoir response to fracture swarms. The upscaling law is derived based on an energy equivalence argument and validated through multiscale simulations using a high-fidelity code, GEOS. The swarming fractures are first modeled with a spacing that is much smaller than the cluster spacing; these fractures are then approximated by an upscaled, single fracture based on the proposed upscaling law. The upscaled fracture is shown to successfully match the energy input rate and produce the total fracture aperture and average propagation length of the explicitly simulated swarm. Afterward, the upscaling approach is further implemented in 3D field-scale simulations and validated against the HFTS microseismic data of a horizontal well. Our results show that hydraulic fracture swarming can significantly affect fracture propagation behaviors compared with the propagation of single fractures as assumed by conventional modeling approaches. Under the considered situations, the conventional treatment yields fast propagation speed that far exceeds that indicated by the microseismic data. We also illustrate that this discrepancy can be reduced readily through the implementation of the upscaling law. Our results demonstrate the importance of accounting for the fracture swarming effect in field-scale simulations and the efficacy of this approach to enable realistic predictions of reservoir responses to fracture swarms, without the need to model tightly spaced fractures individually.
Differential expression profiles of lncRNAs and mRNAs during male germ-like cell differentiation in human umbilical mesenchymal stem cells by RNA-seq
Authors: Xie Lichun , Zhou Guichi , Ma Lian , Wen Feiqiu
Published: March 2021

Background: Long non-coding RNAs (lncRNAs) are key regulators of various biological processes and crucial for cell development and differentiation. However, their roles in the differentiation of human umbilical mesenchymal stem cells (HUMSCs) into male germ-like cells remain largely unknown. Method: Here, the expression of lncRNAs and mRNAs in undifferentiated HUMSCs and HUMSCs undergoing differentiation into male germ-like cells was analyzed. RNA-sequencing was performed to profile the expression of non-coding RNAs. We analyzed the total expression of lncRNAs/mRNAs at three time points during HUMSC differentiation [day (D)7, D14, and D21]. Result: Expression profiling revealed 110 lncRNAs, 584 mRNAs, and 21 miRNAs common to the three experimental groups during HUMSC male germ-like cell differentiation. The maximum and minimum total overall lncRNA expression occurred on D14 (638) and D21 (283), respectively. The maximum and minimum numbers of up-regulated mRNAs were observed on D21 (2,398) and D7 (2,106), respectively. The maximum and minimum numbers of down-regulated mRNAs were observed on D14 (3,357) and D21 (202), respectively. The expression level of mRNA ENST00000486554 was up-regulated on D7, D14, and D21 after induction. Pathway analysis identified meiotic signaling pathways and nitrogen metabolism as being associated with the differentiation potential of HUMSC male germ-like cells. Non-coding RNA expression profiles significantly differed in HUMSC male germ-like cell differentiation. One mRNA, ENST00000486554, was crucial for differentiation. Conclusions: Our results provide a systematic perspective on the potential functions of non-coding RNAs and novel insights into the complicated regulatory mechanisms underlying the differentiation of HUMSCs into male germ-like cells.

Published: March 2021

Certain anthropogenic activities have negative impacts on the aquatic ecosystems. Plankton are sensitive to their environment and are used to monitor anthropogenic impacts. A South-eastern Nigeria River was studied from December 2017 to November 2018 in 6 stations; to assess the plankton community, water quality and anthropogenic impacts. The river was subjected to intense sand mining activities among other activities. The plankton was sampled with filtration method while water was collected and analysed using standard methods. A total of 36 phytoplankton species and 27 zooplankton species were recorded with Chlorophyceae and Rotifers being the most abundant groups. The most abundant species - Melosira granulata (phytoplankton) and Daphnia pulex (zooplankton) are pollution indicators. Some of the physicochemical parameters showed that the river was perturbed by the anthropogenic activities in the watershed. However, the plankton assemblage and community structure gave an indication of a stable environment; though the zooplankton fauna showed some level of stress. The impacts of sand mining activities on water quality and plankton were more in the downstream stations (4–6) where sand mining was intense while perturbation from swimming children and related activities were observed in station 1 especially during the dry season. The presence of eutrophic indicators and tolerant species showed that the river was tending towards eutrophication. Sand mining activities contributed to the nutrient enrichment of the river. CCA showed the major water quality parameters that influenced the plankton community structure. There is need to regulate illegal sand mining activities in the river.

Published: March 2021

BackgroundThe burden of tobacco-associated disorders is prevalent worldwide. Over the years, many innovative internet-based approaches have been utilized with variable success to quit tobacco. Though the effectiveness of internet-based and face-to-face interventions on quitting smoking are very well reported in the literature, due to limitation in methodology and limited sample size, it is required to integrate and analyze these studies' findings to reach a single conclusion. The study evaluated the effectiveness of the internet as an intervention approach versus face-to-face interaction on reducing tobacco use as control among adults.MethodsA systematic search was performed through various electronic databases such as Medline, PsychInfo, PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), ResearchGate, Google Scholar, and Academia. Reference lists of the eligible articles were also screened. Full-text articles were included as per eligibility criteria (PICO framework). No ethnicity restriction was applied.ResultsA total of 13 studies were selected for meta-analysis, with 3852 and 3908 participants in intervention and control groups respectively. Forest plot favours the intervention group at one month follow up for tobacco quitting (OR: 2.37, CI: 1.86-3.02, P-0.00001, I2 =0%), at three months (OR: 1.88, CI: 1.48-2.40, P-0.00001, I2 =42%) at six months (OR: 2.02, CI: 1.64-2.50, P-0.00001, I2 =38%) and at 1 year of follow-up (OR: 1.43, CI: 1.18-1.74, P-0.00001, I2 = 36%) comparing to control group. ConclusionInternet and web-based interventions are highly useful in tobacco quitting at one month, three months, six months, and one year of follow-up compared to face-to-face interaction or no intervention, although the level of evidence was moderate. Additionally, limited availability of trials in developing countries, arising need for research of internet use in developing countries to quit tobacco.

Published: March 2021

Aufgrund des technologischen Fortschritts stellt die Entwicklung von medienbezogenen Kompetenzen eine sich stetig wandelnde Aufgabe dar, die durch Angebote der Erwachsenenbildung und Weiterbildung unterstützt werden kann. Um Kompetenzausprägungen sowie Entwicklungsbedarfe bei Lehrenden und (potentiellen) Zielgruppen von Bildungsangeboten zu identifizieren, wird bereits über verschiedene Wege und mit unterschiedlichen Methoden versucht, medienbezogene Kompetenzen zu erfassen. Im Rahmen dieses Beitrags werden zunächst verschiedene Arten der Kompetenzmessung aufgezeigt und anschliessend drei Ansätze der medienbezogenen Kompetenzerfassung bei Erwachsenen exemplarisch betrachtet (Rammstedt 2013; Rott 2020; Treumann et al. 2002). Vergleiche von Selbsteinschätzungsskalen mit einem Testinstrument im Rahmen des Bildungsmonitorings sowie einem Kompetenztest zeigen jeweils spezifische Potentiale, Grenzen und Optimierungsmöglichkeiten der einzelnen Instrumente und Erhebungsarten auf, mit der Schlussfolgerung, dass eine Kombination aus Selbsteinschätzung und Kompetenztests weitere Möglichkeiten für Forschung und Praxis im Feld der Erwachsenenbildung eröffnet, auch wenn kritisch hinterfragt werden muss, welche Art medienbezogener Kompetenzen für welche erwachsene Zielgruppe überhaupt relevant ist.

The article devoted to the analysis of the institute of protection of the right to the image of an individual as a personal intangible right. The paper examines the features of protection of the right to the image of an individual, the features of the image itself as an object of intellectual property rights, its main features, and so on. Interest in the chosen topic arose due to the fact that in modern times is gaining popularity photos and videos (personal photo shoots, professional photo shoots, the use of video clips for advertising, to promote certain content or use in social networks). However, in the process of exercising the right to an image of an individual, it is necessary to determine what opportunities an individual has in case of violation of his right to image, use and disclosure without his permission, and what actions an individual can take to protect his personal non-property right. At the same time, civil legislation, which should regulate the protection of the person and contain effective means of protecting the rights of persons to their image, does not sufficiently provide for this. Therefore, the main purpose of this article was first: to identify the features of the right to an image as an object of intellectual property rights; secondly: to analyze the legislation governing copyright in images; thirdly: to analyze domestic and international practice of protection of the right to images; fourthly: to identify ways to protect the right to depict an individual as a personal non-property right. When studying and analyzing both legal acts and works of legal scholars dealing with the problem of copyright protection, including the right to images, it became clear that the right to images contains several powers that may need protection, namely: the right to conduct photo, film, television or video shooting; the right to use the image; the right to distribute the image; the right to individuality, etc. Therefore, the right to an image is a set of powers, each of which may need protection in case of violation. Thus, in this paper we try not only to identify and outline the problem of application of remedies for the right to the image of an individual, but also to provide recommendations for the implementation of such a right.

Published: March 2021

The article examines corporate environmental crime as the largest type of environmental crime. The concept of “environmental offense” is analyzed. The definition of corporate crime in relation to the environmental aspect is given. The direct and long-term consequences of corporate environmental offenses are described. The current state of the investigated crime, which is characterized by the lack of legal regulation of legal liability of corporations, generally low penalties for this type of offense, inefficiency of law enforcement and environmental authorities to identify and prosecute offenders and, finally, increased latency. The state of the fight against environmental offenses in the United States is presented, and as an example, the state response to large-scale pollution of the Gulf of Mexico is studied. A criminological description of the most typical for Ukraine offenses against the environment: water pollution (unauthorized discharge of ballast water by sea vessels, as well as pollution of petroleum products, sewage, water in seaports and recreation areas), violation of the law on continental (marine) economic zone of Ukraine (illegal exploration and development of natural resources, operation of installations and structures for industrial purposes), large-scale deforestation, depletion of chernozems, “environmental smuggling”. It is stated that the inefficient system of state environmental policy and its regulatory regulation increasingly demonstrates inconsistency with existing threats of a natural nature, which leads to a violation of the constitutional right of citizens to environmental safety. In conclusion, we justify the need to pay special attention of society and of the state to the corporate nature of environmental crime to create a system to combat these offenses. We point out the need for an urgent solution by the science of criminal law and the legislator of the existing problems in doctrinal issues of determining the guilt of the corporation as a basis for prosecution, bringing the perpetrators, including corporations, to special types of liability.

The article discloses the essence and legal foundations of state control over the activities of the Judicial Security Service and covers the main theoretical and legal problems in this area. The author examines the approaches of domestic scientists to the essence of the concept of control and state control in the field of justice. It has been established that scientists consider state control in a narrow sense as control of the executive authorities. However, the state control over the Judicial Security Service is carried out by the State Judicial Administration – a state body in the justice system that belongs to the judicial branch of government, therefore it exercises state control. Thus, the concept of state control goes beyond the limits of the activities of executive authorities, requires analysis and further research. The article analyzes the legal acts regulating the powers of the subjects exercising state control over the Judicial Security Service. It has been determined that the main subject of state control over the activities of the Judicial Security Service is the State Judicial Administration of Ukraine. It has been established that the High Council of Justice is a control and oversight body in the field of justice with a wide range of functions and powers and directly acts as a subject of state control in relation to the Judicial Security Service. It is concluded that state control over the activities of the Judicial Security Service is a system of organizational and legal forms of ensuring compliance with the principle of the rule of law, the fulfillment of tasks, and the implementation of managerial decisions in the activities of the Judicial Security Service, which is carried out on the basis and within the framework of the legislation by the State Judicial Administration and the Supreme Council of Justice to ensure the safety and independence of the court.
