Published: July 2023

The utilization of stone dust waste produced from PLTU Ketapang coal combustion process is still below optimal level. Produced waste reached ± 23,13 ton /day which consists of 99,5% of fly ash and 0,5% bottom ash. As a result, the writer gained an idea of using fly ash as a filler in bitumen mixture, especially in Hot Rolled Sheet  – BASE (HRS – BASE). The study was aimed to compare fly ash and stone dust if used as filler in Hot Rolled Sheet  – BASE (HRS – BASE) mix in marshall test including void analysis which consistsed of VMA, VIM, VFB, and MQ. The planned test item concentration of tar was on the level of 6%, 6,5%, 7%, 7,5%, and 8%. The mixture which used stone dust as filler resulted in optimum bitumen content of 6,90% and the result of marshall test diplayed 912,072 kg of stability, 3,333 mm flow, 4,306%  VIM, 18,018 % VMA, 82,681% VFB, and 273,745 kg/mm MQ.  In the mixture which used fly ash as the filler resulted in optimum bitumen content of 7,1% with the marshall test displayed 877,132 kg of stability, 3,433 flow, 3,985% of VIM, 18,150% VFB, and the Marshall Quotient (MQ) 255,716 kg/mm.

Precise linker length, shape and linker attachment point are all integral components to designing efficacious PROTACs. Due to the increased synthetic complexity of these heterobifunctional degraders and the difficulty of computational modelling to aid PROTAC design, the exploration of structure-activity-relationship (SAR) remains mostly empirical, which requires a significant time and resource investment. To facilitate rapid hit finding we developed capabilities for PROTAC parallel synthesis and purification by harnessing an array of pre-formed E3-ligand linker intermediates. In the next iteration of this approach, we developed a rapid, nanomole-scale PROTAC synthesis methodology using amide coupling that enables direct screening of non-purified reaction mixtures in cell-based degradation assays, as well as logD and EPSA measurements. This approach greatly expands and accelerates PROTAC SAR exploration (5 days instead of several weeks) while using nanomole amounts of reagents. Lastly, it avoids laborious and solvent-demanding purification of the reaction mixtures, thus making it an economical and more sustainable methodology for PROTAC hit finding.
Potential of Mean Force Calculation Using Non-Uniform Sampling Windows for Optimal Computational Efficiency
Authors: Vasudevan Naveen Kumar , Li Dongyang , Xi Li
Published: July 2023

Free energy calculation in molecular simulation is an computationally expensive process. Umbrella sampling (US) is a go-to method for obtaining the potential of mean force (PMF) along a reaction coordinate. Its computational cost increases drastically as the molecular system gets more complex. For many polymeric and biomolecular systems, adequately sampling all configurational degrees of freedom is computationally prohibitive. Using the adsorption of a short-chain methylcellulose on a cellulose crystalline surface as the test case, we show that the sampling time required for reliable results is much higher than typical choices made in the literature. The accuracy of the PMF profile is strongly affected by sampling inadequacy in a few regions along the reaction coordinate. We propose to use non-uniform windows and sampling parameters to enhance the sampling in difficult regions. Sampling windows that vary with the local PMF steepness are allocated with a new algorithm. Parameters in this algorithm are optimized for best sampling efficiency. We demonstrate that significantly less computer time would be required to achieve the same sampling accuracy if computational resources are optimally distributed along the reaction coordinate.

Published: July 2023

The construction of molecular carbon frameworks stands as the fundamental objective of organic chemistry. The carbon skeleton of each organic molecule serves as the foundation for its three-dimensional structure, playing a pivotal role in determining its physical and biological properties. Within the realm of synthesis, the ability to access complex molecules while prioritizing skeletal diversification serves as a crucial factor in advancing the frontiers of efficient synthetic design. In line with this pursuit, our team has developed a versatile synthetic strategy. This strategy not only enables structural diversification but also facilitates the metamorphosis of complex molecular frameworks, such as the taxane diterpenes, into one another. Through our innovative approach, we have unlocked the transformative power to interconvert and manipulate these intricate structures. The implications of our findings extend beyond conventional synthetic chemistry, presenting exciting opportunities for creating a diverse array of molecules with unparalleled flexibility. This achievement opens new avenues for exploration and holds promise for future advancements and applications in this dynamic scientific field.
Impact of stress on hemostasis: A review
Authors: Salukhov Vladimir V. , Kharitonov Mikhail A. , Varavin Nikita A. , Krasovskaya Alisa S. , Santakov Alexander A.
Published: July 2023

The article presents an overview of current views of changes in the hemostasis system in response to stress. Stress-induced neurohormonal responses activate the clotting system and inhibit the fibrinolysis system, leading to hypercoagulation. An evolutionary interpretation of such responses is that hypercoagulation under stress protects a healthy body from excessive bleeding in case of trauma in fight-or-flight situations. Acute psychological stress can cause significant hemoconcentration and prothrombotic changes in the blood, which can have potentially harmful effects on the cardiovascular system.

Published: July 2023

The treatment of sewage is essential to ensure the health and quality of life of the population. When sewage is not treated, we have the contamination of rivers, streams and groundwater, harming the local fauna and flora and putting the health of people who consume this water at risk. This basic service, guaranteed by the Federal Constitution, is a distant reality in small towns in Brazil. In the city of São Gabriel da Cachoeira, northwest of the State of Amazonas, due to the scarcity of financial resources for an adequate infrastructure, the waste and sewage effluents produced by the residents on the banks of the Mauixi stream are dumped directly into the water glass without the proper treatment.

Chemical dyes applied to textiles in the textile processing stage bring serious damage to the environment and human beings involved in the processes. The use of natural dyes in place of chemicals brings benefits in the social and environmental spheres, since highly polluting toxic chemicals are not used in their processes. Despite the importance of its use, many people opt for chemical dyeing over natural dyeing, believing that its colors are scarce. Therefore, the research intends to present a varied color chart using natural dyes applied to natural fibers through applied, qualitative, descriptive research and technical procedures in order to demonstrate the possibility of offering varied colors from natural dyes. A chart of 80 natural colors was made using only 14 plants and residues. In this way, the research contributes to the dissemination of knowledge and encouragement to the consumption of textile pieces based on pro-sustainability practices in fashion. It was verified that it is possible to offer a varied range of colors with the use of natural dyes applied to textiles.
The Architect’s Role to Space Production in Brazil and Germany
Authors:   Berlin International University of Applied Sciences, Préve Camila Vieira
Published: July 2023

It is not new to talk about investor-led building production as a contrast to common needs, though the architect is rarely mentioned as an important figure in these phenomena. Neither are the users and the community initiatives, who seek process changes, becoming therefore the link that justifies and further feeds the space-production-cycle with arguments. Architecture is widely discussed in terms of technicalities and production efficiency among its own technician circle, with little regard to its means to promote better living conditions where users, not only investors, are important drivers. The essential definition and visualization by the architects of their own profession and their role in society - hypothetically defeated - is the trigger to allow any changes in the sector to happen.

The Efficacy of Selected Insecticides Against Wheat Aphids on Irrigated Wheat in North Western Amhara, Ethiopia
Authors: Andualem Mequanint , Asaye Gebremariem
Published: July 2023

Aphid infestations cause significant losses in wheat production. The experiment was conducted at the Koga irrigation site during 2021 to evaluate the efficacy of commercial insecticides for the management of wheat aphids. Seven types of insecticides with unsprayed control were laid in a completely randomized block design with three replications. The result showed a reduced aphid infestation with maximum grain yield were from dimethoate, imidacloprid, lambda-cyhalotrin, profenfos + lambda-cyhalothrin, imidacloprid + lambda-cyhalothrin, and profenofos-sprayed plots. However, the greater net benefit and marginal rate of return were provided by the applications of imidacloprid and dimethoate insecticides. The economically feasible insecticide application can be considered as an effective aphid management practice in wheat production.

Background. Overweight and obesity are key factors for the occurrence of many morphofunctional disorders in organs and tissues, including bronchopulmonary system.The aim. To study the influence of metabolic disorders that occur against the background of obesity on the state of the airways tone in rats.Materials and methods. Obesity in male Wistar rats was induced using a high-fat and high-carbohydrate diet. In animals, body weight and fat mass were measured, and the heart-lung complex was extracted. In blood serum, the levels of glucose, insulin, leptin, triglycerides, and cholesterol were assessed. Bronchoalveolar lavage fluid was obtained by an open method, in which the concentration of protein, interleukin (IL) 6 and IL-10 was determined. The contractile activity of the isolated bronchial smooth muscle segments was studied using mechanographic method. The effect of acetylcholine (10–7–10–4 M), indomethacin (10–5 M), and forskolin (10–7–10–5 M) on the changes in the tone of airway smooth muscles was assessed.Results. High-fat and high-carbohydrate diet caused an increase in body weight, visceral obesity, hyperglycemia, insulin resistance, leptinemia, dyslipidemia in rats of the experimental group. In the bronchoalveolar lavage fluid of experimental animals, an increase in the content of protein and IL-6 was found, which positively correlated with the level of leptin and the fat mass. In obese rats, the contractile responses of bronchial smooth muscle segments increased in response to the effect of the cholinergic agent acetylcholine. The bronchoconstrictor effect of acetylcholine was reduced by the cyclooxygenase inhibitor indomethacin. In turn, the adenylate cyclase activator forskolin caused relaxation of the airway segments smooth muscles in rats of both groups, which was more pronounced in the experimental group.Conclusion. The obtained results indicate that the change in the reactivity of the respiratory tract can be the cause of  bronchospastic conditions in obesity and of the inflammatory reaction in the respiratory system induced by obesity.

Background. Low-grade inflammation is currently one of the main risk factors for the development of adverse events in the cardiovascular system, including death from cardiovascular diseases or their complications that cause mortality in the postCOVID period.The aim of the study. To assess the impact of health resort treatment in the conditions of the Southern Coast of Crimea on clinical and functional parameters, as well as on the level of systemic inflammation in patients after a new coronavirus infection.Materials and methods. The study included 67 patients (54.9 ± 9.05 years) in the post-COVID period who underwent health resort treatment at the I.M. Sechenov Academic Research Institute of Physical Treatment Methods, Medical Climatology and Rehabilitation. Methods of health resort treatment included climatic treatment on the Southern Coast of Crimea, therapeutic breathing exercises, terrainkur, and various methods of respiratory therapy. In all patients, the study of the C-reactive protein (CRP) in peripheral blood upon admission and at discharge was carried out.Results. Despite a statistically significant improvement in most clinical and functional parameters, the level of CRP and the number of leukocytes and their subpopulations in peripheral blood in patients who underwent health resort treatment did not differ significantly (p > 0.05) from the baseline values obtained upon admission at the I.M. Sechenov Academic Research Institute of Physical Treatment Methods, Medical Climatology and Rehabilitation. The CRP index upon admission and at discharge corresponded to the lower limit of the interval specific for low-grade inflammation (from 3 to 10 mg/l).Conclusion. Our results indicate the lack of effectiveness of the presented plan of health resort treatment in the correction of low-intensity inflammation, as well as the necessity for deeper scientific research in the direction of studying the mechanisms of low-grade inflammation development and the methods of its management.

Control valve is a tool in the oil and gas industry that works by relying on actuators as a driving force. For example, pneumatic actuators work with air pressure as driving energy, and standard signals are used for pneumatic. The signal is converted into a current signal using fuzzy as an application of artificial intelligence systems in the industrial sector. The method used in this study is the utilization of fuzzy logic with the Mamdani method using the software MATLAB. The results will be compared with data from companies and P/I simulation data. Pressure pneumatic algorithm system fuzzy by paying attention to the range of signals used. Company data and P/I converter simulation data are not much different, but the line equation obtained is slightly different. Meanwhile, the fuzzy logic data has slightly different data from the previous data caused by the rules of the fuzzy. Thus, the use of fuzzy logic pressure pneumatic signals to flow signals can be said to be quite capable of being used in these systems by paying attention to the range of signals and rules needed. The comparison results that have been tested have data results that are not much different based on the difference in the value of the current signal and the error value obtained below 2.5%.

Rad se oslanja na istraživanja Johna McCormicka, Zakija Laïdija, Sabine Saurugger, Renauda Dehoussea, Hansa Vorländera, Gilberta Merlioa i drugih, a koja se bave teorijom europske integracije, mirotvornim aspektima europske integracije, prednostima i nedostacima političkog sustava Europske unije, te snagama i slabostima europske demokracije. Na temelju McCormickove analize pojedinačno se istražuju aspekti mirotvornoga kapaciteta djelovanja Europske unije, kojima se priključuje kritika specifične »normativne sile« Europske unije, kakvom je opisuje Laïdi. Rad zaključuje da u uvjetima globalnih kriza, naročito u oblicima ratnih sukoba, djelovanje Europske unije u području mirotvorstva pokazuje značajne manjkavosti, koje se temelje na unutarnjim predispozicijama ovoga specifičnog političkog sustava.

Društveno poduzetništvo kao nov način poslovanja područje je spajanja poduzetničkih praksi iz poslovnog svijeta i vrijednosti povezanih s društvenom odgovornosti i načelima održivog razvoja. Braniteljske zadruge i zadruge ratnih veterana globalno su prepoznati modeli razvoja društvenog poduzetništva. Usprkos dugoj tradiciji zadrugarstva u Republici Hrvatskoj (RH), ono još uvijek nije široko korišteni poslovni model. Cilj je istraživanja predstavljenoga u ovome radu da se analizom stanja i praksi ukaže na potencijal koji braniteljske udruge i zadruge imaju kao značajan oblik društvenog poduzetništva u hrvatskom kontekstu u perspektivi društvenih poduzeća za radnu integraciju. S obzirom da ova tema u hrvatskoj znanosti do sada nije bila primjereno istraživana, provedeno recentno istraživanje pokazuje kako bi braniteljske socijalno-radne zadruge mogle doprinijeti razvoju društvenog poduzetništva u RH, ostvarenju održivog i društveno odgovornog poslovanja te socijalnoj i radnoj integraciji ranjivih skupina.

U tekstu se razmatra način na koji se u hrvatskom javnom prostoru tijekom 19. stoljeća tematizirao status siromaha te osoba koje su bile proglašene umobolnima. Istraživanje se temelji na analizi tekstova iz najstarijih sačuvanih novina koje su objavljivale na hrvatskom jeziku te strukovnih glasila liječnika i učitelja koja su izlazila tijekom 19. stoljeća. Polazna pretpostavka je da tiskovine namijenjene širem krugu čitatelja i posvećene aktualnim događajima svoje sadržaje oblikuju prema postojećim trendovima u javnom prostoru. Autori novinskih članaka često ukazuju na predrasude i diskriminaciju spram marginaliziranih skupina, pritom nastojeći potaknuti emocionalnu reakciju čitatelja. Novinski napisi također ukazuju i na specifičan status pojedinih bolesti uma i tijela. Nadalje, urednici novina, jednako kao i liječnici i učitelji u svojim strukovnim glasilima, jasno uočavaju povezanost između života u neimaštini s tjelesnim i duhovnim propadanjem pučanstva. Velike nade polažu se u obrazovanje koje, prema tadašnjem razumijevanju, ima moć sprječavanja slaboumnosti.
Integrated optical frequency Kerr microcomb applications
Authors: Moss David
Published: July 2023

Optical microcombs represent a new paradigm for generating laser frequency combs based on compact chip-scale devices, which have underpinned many modern technological advances for both fundamental science and industrial applications. Along with the surge in activity related to optical micro-combs in the past decade, their applications have also experienced rapid progress ‒ not only in traditional fields such as frequency synthesis, signal processing, and optical communications, but also in new interdisciplinary fields spanning the frontiers of light detection and ranging (LiDAR), astronomical detection, neuromorphic computing, and quantum optics. This paper reviews the applications of optical microcombs. First, an overview of the devices and methods for generating optical microcombs is provided, which are categorized into material platforms, device architectures, soliton classes, and driving mechanisms. Second, the broad applications of optical microcombs are systematically reviewed, which are categorized into microwave photonics, optical communications, precision measurements, neuromorphic computing, and quantum optics.

The Gendered Persistence of Authoritarian Indoctrination
Authors: Elsayed Nourhan A. , Hilbig Hanno , Riaz Sascha , Ziblatt Daniel
Published: July 2023

A large literature has studied the effects of socialization under authoritarianism on political attitudes. In this research note, we extend this literature by demonstrating striking gender disparities in the post-transition persistence of these effects. We study the case of authoritarian indoctrination in the German Democratic Republic (GDR) using a regression kink design for causal identification. First, we draw on a unique survey fielded right before reunification to show that education under authoritarianism substantially reduced support for democratic capitalism and reunification with the West. In the second step, we triangulate multiple contemporary data sources to trace the persistence of these effects over time. Three decades after the fall of the GDR, the attitudinal effects of authoritarian indoctrination persist only among men, but not women. Our results highlight considerable heterogeneity in the persistence of authoritarian legacies, raising critical questions about post-authoritarian "re-socialization" and gendered adaptability.
Reflection mirrors, optical gyroscopes, filters, and wavelength interleavers achieved with Sagnac interference in integrated photonics
Authors: Moss David
Published: July 2023

As a fundamental optical approach to interferometry, Sagnac interference has been widely used for reflection manipulation, precision measurements, and spectral engineering in optical systems. Compared to other interferometry configurations, it offers attractive advantages by yielding a reduced system complexity without the need for phase control between different pathways, thus offering a high degree of stability against external disturbance and a low wavelength dependence. The advance of integration fabrication techniques has enabled chip-scale Sagnac interferometers with greatly reduced footprint and improved scalability compared to more conventional approaches implemented by spatial light or optical fiber devices. This facilitates a variety of integrated photonic devices with bidirectional light propagation, showing new features and capabilities compared to unidirectional-light-propagation devices such as Mach-Zehnder interferometers (MZIs) and ring resonators (RRs). Here, we present our latest results for functional integrated photonic devices based on Sagnac interference. We outline the theory of integrated Sagnac interference devices with comparisons to other integrated photonic building blocks such as MZIs, RRs, photonic crystal cavities, and Bragg gratings. We present our latest results for Sagnac interference devices realized in integrated photonic chips, including reflection mirrors, optical gyroscopes, basic filters, wavelength (de)interleavers, and optical analogues of quantum physics.

Mathematical learning disabilities (MLD) are typically defined as difficulties in basic numerical skills. It has been suggested that number processing skills (i.e., enumeration and symbolic number comparison) would differentiate low achievement from more severe difficulties in mathematics. This study investigated the accuracy of number processing skills in identifying students with MLD based on arithmetic fluency and whether the classification ability of number processing skills varied as a function of grade level. Participants were 18,405 students (girls = 9,080) from third to ninth grade (9–15 years of age). Students’ basic numerical skills were assessed with an online dyscalculia screener aimed at identifying students with MLD. Confirmatory factor analyses supported a two-factor structure of the screener, with number processing skills and arithmetic fluency as the two factors. The two-factor structure was invariant across language groups, gender, and grade levels. Receiver operating characteristics curve analyses indicated that number processing skills are a fair classifier of MLD status across grade levels three to nine. The classification accuracy of number processing skills was better when predicting MLD (cut-off < 5%) compared to low achievement (cut-off < 25%) status. Results highlight the need to measure both number processing and arithmetic fluency when identifying students with MLD.

Published: July 2023

Bu makale, Türkiye’nin batı ve güney kıyılarındaki uluslararası turizm merkezlerinde meydana gelen turizm kentleşmesi olgusunu nüfus artış hızı ve iç göç verilerindeki değişimler üzerinden incelemektedir. Bu amaçla çalışmada, Türkiye İstatistik Kurumu’ndan (TÜİK) elde edilen verilerden (1980-2021) hareketle turizm merkezlerinin nüfus artış hızları ve iç göç oranları hesaplanmıştır. Turizm merkezlerinin bu konulardaki istatistiksel değerleri Türkiye’deki diğer yerleşim birimlerine ait değerlerle karşılaştırılmış, böylece turizmin, kentleşmenin nüfus ve iç göç boyutu üzerindeki rolü ortaya konulmuştur. Bulgulara göre; 1980-1990 döneminin nüfus artış hızları, araştırmaya konu olan merkezlerin tamamında tüm sayım dönemlerindeki en yüksek değerler olarak ayırt edilmiştir. Bu dönemdeki nüfus artış hızları kent ölçeğinde karşılaştırıldığında ise incelenen on kentin Türkiye’de %5’lik dilime girerek ilk sıralarda yer aldığı belirlenmiştir. 1980-2021 dönemindeki nüfus artış hızları ilçeler bazında karşılaştırıldığında da turizm merkezlerinin Türkiye’de en yüksek nüfus artış hızına sahip ilçeler arasında yer aldıkları tespit edilmiştir. Uluslararası turizm merkezlerinde, bağlı bulunduğu il dışında doğanların oranları 1985 yılında daha çok %30’un altında kalmışken, 2021 yılında bu oranların önemli bir bölümü %50’nin üzerine çıkmıştır. Söz konusu turizm merkezleri, 1985-2021 döneminde doğum yeri ölçütüne göre de en fazla değişime sahip ilçeler arasında yer almıştır. Sonuç olarak nüfus artış hızı ve iç göç değişkenlerinin, Türkiye’de turizm kentleşmesinin açıklanmasında oldukça kullanışlı olduğu görülmüştür.
Ethical Issues and Insecurity in Africa: The Media Dimension
Authors: Aondover Eric Msughter  , Martha Msoo Hile  , Suleiman M. Yar’Adua
Published: July 2023

This paper addresses ethical issues and the challenges of insecurity in connection to mass media and journalistic practice in the context of Africa. In communication studies, ethics is central and critical to the issue of insecurity in Africa, especially to the credibility in the gathering, processing, and delivery of information for believability. Insecurity constitutes a major impediment to the development of Africa. There are multiple points of violent conflicts, acts of terrorism, kidnapping, and crimes. Many countries in Africa are faced with threats ranging from armed banditry, cattle rustling, armed and sea robberies and piracy, militancy, cultism, pipeline vandalism, illegal oil bunkering, and crude oil theft, illegal refining of petroleum, herdsmen-farmers clashes, activities of IPOB and other separatist groups. All of these make society tense, dangerous, and conflict-ridden with implications on journalism, its ethical practice, performance, and credibility. For an individual or people to internalize, accept, believe and actualize the content of information, such an individual or people must adjudge the source and content of the information based on truthfulness, competence, dynamism, and relevance. Often time, the challenges of insecurity in Africa are accelerated due to the way media handle such issues. When an individual is sufficiently and ethically informed, he or she becomes knowledgeable on a particular subject and the mind is freed from uncertainty, liberated from ignorance, and empowered to effectively participate in the process of national development. The growth and development of Africa have continuously failed to correlate with the quantum of resources allegedly expanded over time. Within this context, this paper examines ethics in journalistic engagement and the issues of insecurity in Africa.
Newspaper Content Analysis of 2012-2015 Ombaste Ethnic Conflict in Nasarawa State: A Framing Theory Perspective
Authors: Sabiu Garba  , Aondover Eric Msughter
Published: July 2023

This study examined the newspaper coverage of the Ombatse crisis that hit Nasarawa State from 2012-2015. The Ombatse was a movement that wanted to resurrect the Eggon culture in a kind of renaissance and ensure a culture of high morality and chastity; laudable as these objectives were, the group suddenly turned dreadful, assuming a more militant posture; attacking and killing enemies real or perceived including security forces in their hundred. The study employed content analysis, which is a quantitative method of data generation. It applied four predetermined frames: actor frame, action frame, reaction frame, and consequence frame. 2112 dailies were censured for the period of four years. Study applied purposive sampling technique in the selection of the Daily Trust and Leadership newspapers where 180 copies of the papers were examined. The found that reaction frame was the predominant slant of the Nigerian newspapers with 61.1% of the news stories as reactions to the Ombatse activities. By implication, the findings revealed vacuity of the Nigerian media in handling a core national issue to which the media itself is a stakeholder. The study recommended that the media must be active participant in addressing, shaping public understanding of social upheaval- because the role of the media during conflict cannot be underestimated. The media should be able to analyse consequences, the possibility of collateral damage on the parties involved, the shadow parties and the by-standers. Nigerian journalists should also be trained and retrained on guide to sensitive-conflict reporting.
