Comparative Analysis of Different Locations of the Shear Wall in Multi-storey Rc Building on Sloping Ground With Flat Ground
Authors: G Sheshadri , R Arun Kumar S , P Radhika Bhandary 
Published: September 2024

Abstract

This research investigates the seismic behavior of G + 15-story reinforced concrete (RC) buildings, emphasizing the impact of shear wall location on buildings situated on both level and sloping sites. Shear walls offer lateral stability and seismic force resistance in high-rise structures. This study assesses the effectiveness of several shear wall structures in various geological settings. There are differences in the centers of mass and rigidity due to the stiffness and mass distribution in these buildings along the vertical and horizontal directions. Increased seismic damage may result from this inconsistency, particularly in buildings situated on sloping terrain where torsional reactions are more noticeable. Such structures often experience greater displacements and base shear forces, with shorter columns being particularly vulnerable to stress and damage. Additionally, buildings with setbacks, where the floors step back toward the hillside, may exhibit unique seismic vulnerabilities. This study analyzes various shear wall placements and compares the performance of structures on flat ground to those on slopes of 10°, 20°, and 30°. The analysis used the Equivalent Static Method and Response Spectrum Method with ETABS 19.1.0 software. The key metrics were story displacement, story stiffness, and base shear values. The findings provide insights into optimizing shear wall placement to improve seismic resilience under diverse terrain conditions.

Abstract

Background
As a common chronic complication of diabetes, diabetic retinopathy (DR) often results in an irreversible visual dysfunction. ATG16L1 might be a potential biomarker of DR. Our study focused on the underlying mechanisms of Atg16L1 in diabetic retinopathy.
Method
In this study, we investigated the role of ATG16L1 in high glucose (HG)-induced retinal capillary endothelial cells (RCECs). Rat RCECs were cultured in normal glucose (NG) or high glucose (HG) medium with or without ATG16L1 transfection.
Results
First, the expression of ATG16L1 mRNA and protein was found to be significantly upregulated in RCECs exposed to HG. Moreover, the migration ability and invasion rate of RCECs in the high glucose group were considerably higher than those in the RCECs of the normal glucose group. The migration ability and invasion rate of RCECs in both normal and high glucose groups decreased significantly after transfection with ATG16L1 siRNA compared to migration and invasion of the RCECs in the control group (P < 0.01).
Conclusion
The results of this study indicated that ATG16L1 might be involved in the development of DR by promoting the migration of RCECs.

Abstract

The study area represents part of Wadi El Abiad in Shalatien province at the extreme southeastern corner of Egypt. It lies at latitude 22○ 51´ 00˝ and longitudes 35○ 14´ 00˝ to occupy an area of about 0.26 km2. The area is essentially covered by Precambrian basement rocks, mainly granodiorite, and characterized by low to moderate topography. The aim of this study is to locate possible structural features and their deposits of mineralization, which hosted primarily in the shear or alteration zones within volcanic rocks. Therefore, integrated geophysical methods were employed through the use of ground magnetic, self-potential, gradient resistivity and induced polarization reconnaissance mapping and detailed 2D resistivity and induced polarization profiling to delineate the mineral ore deposits in terms of depths and extensions. The inspection of RTP map shows the presence of two major faults affecting middle of the study area trending E-W and major NW-SE uplifted trend appears clearly in the first vertical derivative map (FVD). The calculated average depth from the power spectrum curve equal 60 m for the regional component and 30 m for the residual one. At source parameter image (SPI) and analytical signal (AS) maps, the NE-SW, NW-SE, NEE-SWW and NWW-SEE trends show more shallow depth as the presence of basement rocks. The basement relief map illustrates that, the maximum values of the depth to the basement rocks are located nearly at the central part of the map, at extreme east and west edges in the center of the map, and also at the south edge of the map. The apparent chargeability map shows positive anomalies, about 750 msec, to the south. Three of them are located quite coincident along the interpreted faults derived from the magnetic data and correspond to low SP anomalies, about − 20 mv, and relatively low resistivity anomalies, about 75 Ω.m. Such anomalies indicate possible expected mineralization locations in the subsurface. The results of 2D-resistivity and IP inversions indicated that there are different anomalous zones of high conductivity and chargeability at depths ranging from 10 to 20m to indicate probable locations of ore deposits and/or disseminated minerals. At least three of these anomalies were recommended for core drilling and geochemical analysis to evaluate the mineral potentiality of the study area.

Abstract

Insomnia disorder (ID) is not merely a psychiatric disorder but is also closely related to heart health. The role of brain-heart interplay (BHI) in the mechanism of ID and the effect of noninvasive brain stimulation on BHI remains unclear. To explore the BHI in the mechanism of ID and investigate whether tACS affects BHI. Forty-four IDs and 32 healthy controls (HCs) were enrolled. The IDs received θ-tACS targeting F3 for 10 consecutive days. Synchronous electroencephalogram (EEG) and electrocardiogram (ECG) were collected for the IDs before and after treatment. Comparisons of bidirectional BHI indexes based on a synthetic data generation (SDG) model, EEG power, and heart rate variability (HRV), were conducted between IDs and HCs at baseline, as well as changes in these measures before and after tACS. Correlations and mediation analyses between BHI and behavioral assessments were also investigated. IDs exhibited significantly higher BHI in both directions. Correlation results indicated that the Pittsburgh Sleep Quality Index (PSQI) was associated with top-down BHI, while the Hamilton Anxiety Rating Scale (HAMA) was correlated with bottom-up BHI. Additionally, θ-tACS modulated abnormal BHI. Notably, baseline top-down BHI at Fz could predict improvements in sleep quality and depression and mediated the recovery of sleep quality and depression. We extended the hyperarousal theory of ID from a new perspective of BHI. Furthermore, BHI was identified as a potential predictor of clinical outcomes following θ-tACS intervention.
Geospatial Analysis of Timely Access to Neurosurgical Public Care in Peru: Planning the Next Century Marathon
Authors: Bocanegra-Becerra Jhon E. 
Published: September 2024

Abstract

Introduction
Understanding geographic accessibility to neurosurgical care is key to ensuring timely treatment, particularly in countries with challenging topography like Peru. This investigation aimed to estimate Peru's population distribution within critical time intervals and proximity to the nearest neurosurgical facility in the Ministry of Health network.
Methods
A geographical analysis was conducted to examine the distribution of the Peruvian population within six travel areas (1 hour, 2 hours, 4 hours, 6 hours, 1 day, and 5 days) to the nearest facility providing neurosurgical care.
Results
Twenty-five facilities providing neurosurgical care were identified across Peru, of which 92% pertained to tertiary or higher-level facilities and were included in the analysis. Peru’s population was estimated at 32,625,937 people. The most populated area of Peru, Lima, concentrates 52.17% of neurosurgical facilities. Nearly 13,820,347 Peruvian people (42.36%) could lack neurosurgical access within 4 hours of travel. In addition, 72.1% and 89% of Lima and Callao’s population exhibited timely access to neurosurgical care within 1 hour of travel, respectively. About 302,733 people (30.1%) living in the region of Loreto could
access neurosurgical treatment in up to 5 days of travel.
Conclusion
Geographical accessibility to neurosurgical facility care is heterogeneous. Major hospital settings remain centralized in Lima and Callao regions. Virtually 42.36% of the Peruvian population could not access timely neurosurgical care within 4 hours of travel. Notably, roughly one-third of the population in the Amazon region of Loreto could reach a neurosurgical setting in up to 5 days of travel. These findings may be worrisome, yet could incentivize further assessment of underserved areas, prioritize infrastructure development, and synergic policy interventions from governmental and non-governmental organizations.

Abstract

Objective:
This study aimed to evaluate and compare the solubility and calcium ion release of four root canal sealers: Endosequence (bioceramic), BioRoot RCS (bioceramic), MTA Fillapex (tricalcium silicate-based), and AH Plus (resin-based).
Materials and Methods:
Polyethylene tubes (10 mm diameter, 3 mm height) were filled with the respective sealers and tested for solubility by measuring weight loss after immersion in distilled water, and for calcium ion release using an atomic absorption spectrophotometer. The sample size was 20 per group (total N = 80). Intergroup comparisons were conducted using one-way ANOVA with post hoc Bonferroni tests, while intragroup comparisons between time periods were analyzed using repeated measures ANOVA with post hoc Bonferroni tests.
Results:
The results showed significant differences in solubility and calcium ion release among the tested sealers. MTA Fillapex exhibited the highest solubility, ranging from 12.79 ± 0.17 μm on Day 1 to 19.85 ± 0.14 μm on Day 28, while AH Plus had the lowest, with values from -1.05 ± 0.72 μm to -2.32 ± 0.27 μm (Table 1). In terms of calcium ion release, Endosequence Bioceramic sealer demonstrated the highest release, ranging from 10.01 ± 0.22 mg/L on Day 1 to 10.59 ± 0.51 mg/L on Day 28, whereas AH Plus had the lowest release, from 1.98 ± 0.32 mg/L to 0.54 ± 0.13 mg/L (Table 2).
Conclusion:
The bioceramic sealer- Endosequence, demonstrated favorable physicochemical properties in terms of low solubility and sustained calcium ion release compared to the other sealers tested. These findings suggest that the bioceramic sealers may be advantageous for improving the long-term success of endodontic treatment.

Published: September 2024

Diese empirische Studie untersucht, welchen Entwicklungsstand Kinder mit unterschiedlichen Spracherwerbsbiografien (N = 212) bei ihren rezeptiven Fähigkeiten im Deutschen (Verbbedeutung, W-Fragen, Negation) zu Schulbeginn erreicht haben und welchen Einfluss er auf Lesefähigkeiten (Leseverstehen auf Wort-, Satz- und Textebene; Lesegeschwindigkeit) am Ende der ersten und vierten Jahrgangsstufe ausübt. Als Messinstrumente wurden die Diagnoseverfahren LiSe-DaZ (Schulz/Tracy 2011), ELFE II (Lenhard et al. 2018) und WLLP-R (Schneider et al. 2011) herangezogen. Die statistische Auswertung erfolgt mittels IBM SPSS Statistics und beinhaltet neben der deskriptiven Statistik auch Korrelationsanalysen. Im Fokus der Datenanalyse steht die Frage, ob sich Unterschiede zwischen den Kindern mit Deutsch als Erst- und Zweitsprache abbilden lassen können. Es zeigt sich, dass zweitsprachlernende Kinder mit anderen Ausgangsvoraussetzungen in den (Deutsch‑)Unterricht der ersten Jahrgangsstufe eintreten und die Zusammenhänge zwischen rezeptiven gesprochensprachlichen Fähigkeiten und späteren Lesefertigkeiten bei ihnen unterschiedlich gewichtet sind im Vergleich zu Kindern, die von Geburt an mit der deutschen Sprache vertraut sind.

Published: September 2024

Kinder sind beim Schuleintritt unterschiedlich vertraut mit mündlichen Textfähigkeiten wie Berichten, Erzählen oder Erklären. Für die Nutzung schulischer Bildungsangebote sind solche sprachlich-diskursiven Fähigkeiten grundlegend. Ihre gezielte Förderung im Kindergarten kann deshalb zu einer Stärkung der Bildungschancen aller Kinder beitragen. Mit der Interventionsstudie EmTiK wurden Zusammenhänge zwischen dem erwerbsunterstützenden Lehrpersonenhandeln und den mündlichen Textfähigkeiten der Kinder untersucht. Zu drei Erhebungszeitpunkten wurden 65 zufällig ausgewählte Lehrpersonen während jeweils 90 Minuten gefilmt. Vier bis fünf Kinder aus jeder Klasse (N = 293) absolvierten jeweils zwei Tests: eine Nacherzählung eines sprachfreien Trickfilms und einen Test zur Messung der exekutiven Funktionen. Die mündlichen Textproduktionen der Kinder und die Alltagskommunikation der Lehrpersonen wurden mit den neu entwickelten Ratinginstrumenten MuTex und EULE eingeschätzt. Die Lehrpersonen der Interventionsgruppe besuchten eine intensive Weiterbildung. Die Ergebnisse zeigen, dass a) die Kinder im Zeitraum von eineinhalb Jahren ihre mündlichen Textfähigkeiten um rund 50 % ausbauen, b) die Lehrpersonen ihre Erwerbsunterstützung durch Weiterbildung signifikant verbessern und c) eine gute Unterstützung der Lehrpersonen den Erwerb mündlicher Textfähigkeiten begünstigen kann.

This article discusses the thermal technological processes occurring in petroleum coke calcination furnaces, as well as issues of causes of destruction of the refractory material of the calcination furnace lining. The survey showed that the main factors influencing the duration of the work campaign of the lining are the temperature stresses that arise in the lining during sudden temperature changes during heating or cooling, as well as the chemical effect of the process material on the lining.
It was revealed that in the inlet zone, where the drying of technological raw materials is carried out, the wear of the lining occurs evenly, and there is no significant damage. On thermal imaging images, this zone is displayed as uniform temperature fields on the outer surface of the furnace. In the calcination zone, the lining is characterized by the presence of main cracks that run along the seams. These cracks indicate the occurrence of significant thermal stresses when the furnace is heated. Work was done to determine the dependence of tensile strength on temperature, in the temperature range from 20 oC to 650 oC. Analysis of the results of determining the tensile strength showed a general tendency for it to increase with increasing temperature. This is explained by changes in the structure of the refractory material with increasing temperature and load. Taking into account the obtained dependence of the tensile strength on temperature allows one to adjust the heating schedules of the calcination furnace to reduce the temperature stress during the heating process
Production of high-quality casting cores from lignin-based binders using blow-out method
Authors: Al-Saraireh Falah Mustafa 
Published: September 2024

The study examined the feasibility of employing technological lignosulfonates as binders in blowing processes to produce small casting cores for shaped iron castings, analogies to the currently in-use Cold-Box Amin procedure. In the study, it has been demonstrated that lignin materials offer several benefits, including workplace safety, within the foundry itself, and in terms of maintaining environmental hygiene in the vicinity of a similar manufacturing facility. It is indicated that the cost of binders could drop twice when using the suggested lignin components. Mixtures with experimental compositions have been proposed and put to the test. The sand-oligosulfonate mixture's composition has quantitative properties that have been determined. Binders exhibiting stable properties and high strength indicators (up to 3.0 MPa) were developed after processing. The nonionic surfactant class was determined to include the most effective additions. It was experimentally demonstrated that applying specific nonionic surfactant types as technological lignosulfonate modifiers boost and stabilizes properties by a significant order of magnitude (from 0.05 MPa to 0.5–0.7 MPa) %, concerning specific binding ability).
Consequently, excellent cast iron castings and a prototype batch of cores were created. A significant emphasis is placed on developing special machinery for lignin binders
Development and application of a generalized method of determination the roots of the characteristic equation a system tuned to the technical optimum

Published: September 2024

The object of the conducted research is dynamically unstable objects and processes of the third order with a transfer function of the third order
The problem that has been considered and solved is related to the provision of dynamically unstable systems with such a stable state in which transients are set to the technical optimum. Analytical formulas have been obtained to determine the values of the roots of a third-order characteristic equation tuned to a technical optimum. The only variable of the obtained mathematical expressions is the time constant of the system or object, which determines the time of establishment or termination of periodic processes. Since the obtained analytical expressions directly determine the constant coefficients of the polynomial of the characteristic equation based on just one variable, which in the physical sense is a normalized value of the transition time, the synthesis of any dynamically unstable system leads to a state in which the system is optimized, according to the condition of technical optimum. In other words, only the analytical expressions obtained for the coefficients of the characteristic equation determine the system tuned to the technical optimum. Before synthesizing the regulator and feedback, this time constant is set as a set requirement for the time of termination of the transient process. Thus, the formulation of an equation for the coefficients of the characteristic equation of the system is equated to the found equations and the unknown coefficients of the feedback and rcgulator are calculated from the resulting system equation. The practical applications of the obtained results can be limited with two conditions: it is assumed that the dynamically unstable systems under consideration are linear or linelized; the selected solutions and feedback elements are tactically feasible.
The results obtained after applying the proposed technique allow to conclude that by changing the ratio between the values of the adjustable coefficients, the performance is increased by about two times. At the same time, the overshoot does not exceed 6 %, which is normalized by the conditions of the technical optimum
