Published: February 2025

This study explores the performance of alkaline-activated geopolymer binders using industrial by-products and recycled concrete fine aggregate (RCFA) as sustainable alternatives to traditional cement. Materials such as granulated blast furnace slag (GBFS), silica fume (SF), red brick powder (RBP), quick lime (QL), and RCA were utilized to develop eco-friendly binders with enhanced mechanical and durability properties. Experimental tests evaluated physical, mechanical, and microstructural characteristics, including setting times, dry density, flexural strength, and compressive strength. Advanced analysis with SEM and EDAX examined aggregate-binder bonding. Results highlighted the critical role of binder composition in determining performance. Balanced mixtures of GBFS, SF, and RBP achieved superior strength, durability, and compact microstructures, while excessive QL increased porosity, reducing effectiveness. Optimal flexural strength (4.24 MPa at 56 days) was observed for the G30/S40-L20 formulation, underscoring the importance of precise proportions. Composition influenced setting times, with SF delaying gelation and high QL content accelerating it. The findings demonstrate the viability of using RCFA and industrial by-products in sustainable construction, offering a pathway to reduce reliance on traditional cement. The study emphasizes optimizing binder formulations for strength and durability while addressing environmental impacts, encouraging further research into long-term performance under diverse conditions. This innovative approach highlights the potential for integrating recycled and industrial by-products into construction practices to achieve eco-friendly solutions and promote sustainable urban development.

In Ukraine, the demographic crisis exacerbates the importance of the issue of reproductive health.The objective: to study the features of uterine labor activity depending on the level of anxiety of the pregnant woman for improvement the management of pregnancy and childbirth.Materials and methods. During the preparatory stage of the study, we recorded and analyzed electromyohysterograms in 69 women in labor with its physiological course. The normal electromyography indicators with physiological contractile activity of the uterus in labor were determined. At the main stage of the study, we conducted a prospective clinical examination of 124 pregnant women who were interviewed by Spielberger State-Trait Anxiety Inventory and were subsequently divided into 3 groups depending on the level of reactive anxiety: I group – 38 women in labor with a low reactive anxiety level; II group – 35 women in labor with a moderate reactive anxiety level; III group – 51 women in labor with a high reactive anxiety level. Uterine electromyography was performed using a digital USB-oscilloscope «Hantek-6022BE». The level of anxiety in pregnant women was determined by questionnaire (Spielberger State-Trait Anxiety Inventory).Results. Normal labor activity was typical for 57.9% of pregnant women in the I group, 82.9% – in the II group and 60.8% of pregnant women in the III group (p<0.05). The frequency of weak labor activity was significantly different in pregnant women in the I and III groups – 36.8% and 23.5%, respectively, compared with the II group – 14.3% of cases (p < 0.05). Among pregnant women in the III group the hyperactive type of labor activity was detected in 9.8%, which is significantly higher than in the I and II groups (2.6% and 2.9%, respectively, p < 0.05). In pregnant women of the I and III groups the cases of discoordinated labor activity were detected, which was registered in 5.2% of pregnant women in the I group and in 5.9% in the III group, in pregnant women of the II group the discoordinated labor activity was not registered.Conclusions. The study revealed clear changes in uterine contractile activity depending on the level of reactive anxiety, in particular, the indicator of weakness of labor activity at a low reactive anxiety level was almost 2.6 times higher than the indicator in other groups, and hyperactive labor activity at a high anxiety was 3.4 times higher than the indicators of other groups.
Elementy starożytnych koncepcji filozoficznych tianming i tianxia w przywództwie politycznym komunistycznych Chin
Authors: Pawełczyk Adam 
Published: February 2025

Polityczno-filozoficzne koncepcje tianming i tianxia mniej więcej od XI w. p.n.e. były fundamentem legitymizacji władzy politycznej w Chinach. Tianming (‘mandat nieba’) zakładał, że cesarz ma przyzwolenie niebios na sprawowanie władzy, a tianxia (‘wszystko pod niebem’) oznaczało obszar objęty tą władzą. Pomimo wielokrotnych zmian ustrojów – od cesarstwa przez demokrację i dyktaturę po współczesny socjalizm – tradycyjne idee wciąż stanowią ważną wartość dla chińskiego społeczeństwa. Stąd też celem artykułu jest zbadanie, w jaki sposób obecne komunistyczne władze Chińskiej Republiki Ludowej (ChRL) wykorzystują je do sprawowania przywództwa politycznego i do jego legitymizacji. Na podstawie analizy historycznej oraz studium przypadków działań współczesnych władz ChRL autor pragnie dowieść, że obie koncepcje nadal są istotnym aspektem sprawowania władzy w Chinach.
Эволюция самаритянской эсхатологической экзегезы в XI–XIX вв.
Authors: Нофал Ф. 
Published: February 2025

В статье впервые рассмотрено развитие арабоязычной самаритянской эсхатологии, изложенной в жанре комментариев к Пятикнижию в XI–XIX столетиях. Анализу рукописных источников предпослан обзор раввинистических и раннехристианских источников, позволяющих заключить об «эсхатологическом нигилизме» самаритян эллинистической эпохи и обозначить terminus post quem богословствования их потомков о потусторонней жизни. Автор фиксирует количественный и качественный рост текстуальных свидетельств, привлекаемых тремя авторитетными самарянскими авторами: ʼАбу ал-Хасаном ас-Сури, Ибрахимом ал-‘Аййей иИцхаком б. ‘Амрамом, — и выдвигает предположение о постепенном характере легализации учения о бессмертии души и посмертном воздаянии, полностью сложившегося в теологическом дискурсе «гризимцев» только на рубеже XIX и XX вв.
The article for the first time considers the development of the Arabic-speaking Samaritan eschatology, which crystallized in the form of comments on Samaritan Pentateuch in the 11th — 19th centuries. The author points out the quantitative and qualitative growth of textual evidence attracted by three authoritative Samaritan authors (ʾAbū al-Ḥasan al-Ṣūrī, Ibrāhīm al-ʿAyyah and Izḥāq ibn ʿAmram). An assumption is made about the gradual nature of the legalization of the doctrine of the soul immortality and posthumous retribution in Samaritan theological discourse, which developed completely at the turn of the 19th and 20th centuries. The analysis of manuscript sources is preceded by a brief review of Rabbinical and early Christian treatises, which allow us to conclude about the «eschatological nihilism» of the Hellenistic era Samaritans and to designate the terminus post quem of their descendants’ theology about the afterlife.

Carbohydrate malabsorption and non-celiac gluten/wheat Sensitivity: The role of probiotic biomodulation
Authors: Romeo Marcello 
Published: February 2025

In recent years, cases of food hypersensitivity reactions in the Western population have significantly increased, with over 50% of patients with functional gastrointestinal disorders (FGID) believing that food triggers their symptoms. The main culprits include FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) and specific protein components of wheat, such as gluten and amylase/trypsin inhibitors (ATIs). Gastrointestinal symptoms related to carbohydrate malabsorption stem from two primary mechanisms. First, unabsorbed carbohydrates can feed certain gut bacteria, leading to fermentative dysbiosis and gas production, which causes bloating and abdominal distension. Second, a diet rich in unabsorbed sugars draws water into the intestinal lumen, accelerating transit and resulting in diarrhea.Adverse reactions to gluten include celiac disease, wheat allergy, and non-celiac gluten/wheat sensitivity (NCGS/WS). The latter triggers both intestinal and extra-intestinal symptoms, which improve upon gluten withdrawal. Recent studies suggest that, in addition to gluten, other wheat components, such as ATIs and FODMAPs, can contribute to symptom exacerbation. NCGS/WS is associated with intestinal dysbiosis and immune alterations. Although a gluten-free diet is currently considered the only available therapeutic strategy, it may negatively impact gut microbiota and the bioavailability of minerals and vitamins.Recent research suggests the use of strain-specific probiotics to improve fermentative dysbiosis, reducing gas-producing species and enhancing the digestion and absorption of carbohydrates, gluten proteins, and micronutrients. In conclusion, an integrated approach combining a low-FODMAP diet (LFD) with specific probiotics could be an effective strategy for managing carbohydrate malabsorption symptoms in FGID, restoring intestinal homeostasis, and counteracting associated microbial hyperfermentation.

Published: February 2025

This study examined the effect of coconut fiber (CF) content on the properties of unfired building bricks (UBBs) using fly ash (FA) and bottom ash (BA) from the Nghi Son coal-fired thermal power plant (CTP). Cement and FA served as binders while BA replaced crushed stone as the fine aggregate. Raw brown CFs were treated with a 5% NaOH solution at 50 °C to increase their mechanical properties. The treated CFs were then cut to a short length of 15 mm and had an average aspect ratio of 103. Brick samples were cast with CF content at ratios of 0%, 3%, 6%, and 9% by binder weight (CF/B) and water-to-binder (W/B) ratios of 0.30 and 0.35. The UBBs were formed under a low pressure of 0.5 MPa and tested to evaluate the effects of CF/B and W/B ratios on brick properties. Results showed that compressive strength (CS) increased with higher CF content, with all samples exceeding 10 MPa after 28 days, classifying them as grade M10 per TCVN 6477:2016. The optimal CF content was 6%, which yielded the highest CS. Increasing CF content reduced unit weight (UW), ultrasonic pulse velocity (UPV), and thermal conductivity (TC), while water absorption (WA) increased. Conversely, a lower W/B ratio improved CS, UW, UPV, and TC, while reducing WA. Microstructural observations revealed that CF acts as a bridge connecting cracks, which helps restrain crack widening and enhance CS.
Abating Heat Accrual During Exercise in Microgravity and Implications for Future Long-Term Missions
Authors: Maguire Katherine , Wydotis Margaret , Bollinger Lance , Caruso John 
Published: February 2025

INTRODUCTION: Space agencies will embark on manned journeys to Mars on smaller vehicles than those used previously. In-flight exercise on those flights must abate the adverse effects microgravity (μG) has on humans. Due to space constraints on these vehicles, a single exercise device must address multiple fitness needs. Exercise and μG individually cause body heat accrual. During in-flight exercise they conspire to exacerbate heat gain. Given the duration of Mars missions and volume of exercise they entail, excess heat accrual must be addressed.
METHODS: This review presents data on μG, thermoregulation, and exercise. Since their relationships are impacted by other variables, energy balance, body water, and cerebral and vascular physiology are discussed. Data are integrated to acknowledge the challenges long-term missions, and the in-flight exercise that accompanies them, impose on thermoregulation. Strategies to limit heat accrual are discussed.
RESULTS: Current in-flight exercise and hardware will not address heat accrual mitigation or operational performance needs for Mars missions.
DISCUSSION: This review suggests for future missions, crewmembers: 1) consume beverages with high sodium contents; 2) employ palm cooling for conductive heat transfer; and 3) perform plyometric exercise on gravity-independent hardware. Research should continue to evaluate these treatments to abate heat gain in μG.
