The Influence Of Blasting Waste On Mortar Performance

Dalam campuran mortar, jumlah pasir yang dibutuhkan kira-kira tiga kali lipat jumlah semen yang digunakan. Oleh karena itu, permintaan pasir alam sangat tinggi karena pesatnya pertumbuhan infrastruktur saat ini. Akibatnya, penambangan pasir yang berlebihan telah menyebabkan erosi sungai yang berlebihan dan bahaya lingkungan. Hal ini menyebabkan perlunya mencari bahan alternatif pengganti pasir. Berkaitan dengan hal tersebut, penelitian ini dilakukan untuk mengetahui kinerja mortar dengan limbah peledakan sebagai material pengganti pasir. Limbah peledakan adalah limbah bahan peledak yang berasal dari area pembuatan kapal atau perawatan di anjungan angkut dan operasi militer. Persentase penggantian limbah peledakan terpilih adalah 0%, 10%, 20%, 30%, 40% dan 50%. Hasil penelitian menunjukkan bahwa persentase limbah peledakan yang dapat digunakan sebagai pengganti pasir mencapai 50%, dengan kuat tekan 21.8Mpa yang hampir dua kali lipat nilai sampel kontrol sebesar 14.2Mpa. Di sisi lain, tingkat penyerapan air untuk sampel 50.0% adalah 9.0%, lebih rendah dari nilai mortar kontrol sebesar 9.2%. Sesuai dengan ASTM C1329, kekuatan tekan mortar yang menggunakan limbah peledakan memenuhi kekuatan yang diijinkan untuk struktur.In a mortar mixture, the amount of sand needed is about three times the amount of cement used. Therefore, the demand for natural sand is extremely high due to the rapid growth of infrastructure these days. As a result, the over-mining of sand has caused excessive river erosion and environmental hazards. This has led to the need of finding an alternative material to replace sand. In this regard, this study was conducted to investigate the performance of mortar with blasting waste as a replacement material for sand. Blasting waste is explosive waste from shipbuilding areas or maintenance on transport bridges and military operations. The replacement percentages of blasting waste selected were 0%, 10%, 20%, 30%, 40% and 50%. The result showed that the percentage of blasting waste that can be used as a replacement for the sand is up to 50%, with a compressive strength of 21.8Mpa which was almost double the value of the control sample at 14.2Mpa. On the other hand, the water absorption rate for the 50.0% sample was 9.0%, lower than the value of the control mortar at 9.2%. In accordance with the ASTM C1329, the compressive strength of the mortar using blasting waste complied with the allowable strength for structures.
Evaluating the Impact of Teledentistry on Patient Outcomes, Diagnostic Accuracy, and Satisfaction in a Prospective Observational Analysis

Background Teledentistry, defined as the use of telecommunication technologies for dental care, has emerged as a transformative approach to oral health services. This prospective observational analysis aims to comprehensively assess the impact of teledentistry on patient outcomes and satisfaction, addressing key aspects such as diagnostic accuracy, longitudinal treatment outcomes, and economic and logistical considerations. Methods The study involved 242 participants selected from diverse dental clinics offering teledentistry services. Participants could choose between traditional in-person visits and teledentistry consultations. The teledentistry interventions included remote consultations, diagnostic evaluations, and treatment planning facilitated through virtual communication tools. Baseline assessments captured initial dental conditions, and follow-up assessments were conducted at three, six, and 12 months. Outcome measures included diagnostic accuracy, patient satisfaction, changes in dental conditions over time, and economic and logistical feedback. Results Descriptive statistics revealed baseline characteristics, with participants evenly distributed between in-person and teledentistry groups. However, the overall satisfaction with diagnoses was significantly lower in the teledentistry group as compared to the in-person group (p < 0.001). Longitudinal assessments demonstrated comparable changes in dental conditions between the two groups. Economic feedback highlighted a cost-saving advantage for teledentistry users, with 80% reporting reduced expenses. Conclusion This study highlights the transformative potential of teledentistry in expanding access to oral health services, reducing costs, and providing comparable treatment outcomes to traditional in-person care. Future efforts should focus on enhancing the teledentistry experience, addressing patient satisfaction concerns, and refining the delivery of remote dental care to maximize its benefits for both patients and healthcare systems.
Suitability of Boulder Marl and Marsh Clay as Sealing Substrates for Landfill Capping Systems—A Practical Comparison

The effects of compaction on soil shrinkage behavior need to be considered for engineering long-term durable mineral liners of landfill capping systems. For this purpose, a new three-dimensional laser scanning device was coupled with a mathematical-empirical model to simultaneously determine the shrinkage behavior of a boulder marl (bm) and a marsh clay (mc). Therefore, both materials were precompacted in 200 soil cores (100 cm3) on the basis of the Proctor test results with five different degrees of compaction (bm1-bm5; mc1-mc5). Thus, the shrinkage behavior, intensity, and tendency were determined during a standardized drying experiment. The volume shrinkage index was used to describe the pore size dependent shrinkage tendency and was classified as high to very high (11.3–17.7%) for the marsh clay and medium (5.3–9.2%) for the boulder marl. Additionally, only the boulder marl (bm2), compacted up to 88% of Proctor density, could be installed as landfill bottom liner in drier locations if the local matric potentials did not exceed the previously highest observed drying range (i.e. values below −300 hPa), to avoid crack formation and generation.
Hi-Fidelity Simulation of the Self-Assembly and Dynamics of Colloids and Polymeric Solutions with Long Range Interactions

Modeling the equilibrium properties and dynamic response of the colloidal and polymeric solutions provides valuable insight into numerous biological and industrial processes and facilitates development of novel technologies. To this end, the centerpiece of this research is to incorporate the long range electrostatic or hydrodynamic interactions via computationally efficient algorithms and to investigate the effect of these interactions on the self-assembly of colloidal particles and dynamic properties of polymeric solutions. Specifically, self-assembly of a new class of materials, namely bipolar Janus nano-particles, is investigated via molecular dynamic simulation in order to establish the relationship between individual particle characteristics, such as surface charge density, particle size, etc., and the final structure formation. Furthermore, the importance of incorporating the long range electrostatic interaction in achieving the corresponding final morphology is discussed. The dynamic properties of polymeric solutions are investigated via two parallel pathways. In the first approach, force-extension behavior of the flexible polyelectrolytes is probed via fine-grained Brownian dynamics simulation of the bead-rod model. The presented model accurately incorporates the excluded volume interaction in order to capture the effect of salt concentration on the force-extension response of polyelectrolyte chain as observed in the single chain experiments. It is shown that accurate incorporation of the excluded volume effect on a long chain of more than 500 Kuhn segments is necessary to reach the universal scaling both for equilibrium properties and force-extension response. Next, a new force law is extracted using a

Impact of Dynamically Downscaling Two CMIP5 Models on the Historical and Future Changes in Winter Extratropical Cyclones along the East Coast of North America

This study investigates the impact of dynamical downscaling on historical and future projections of winter extratropical cyclones over eastern North America and the western Atlantic Ocean. Six-hourly output from two global circulation models (GCMs), CCSM4 and GFDL-ESM2M, from phase 5 of the Coupled Model Intercomparison Project (CMIP5) are used to create the initial and boundary conditions for 20 historical (1986–2005) and 20 future (2080–99) winter simulations using the Weather Research and Forecasting (WRF) Model. Two sets of WRF grid spacing (1.0° and 0.2°) are examined to determine the impact of model resolution. Although the cyclone frequency in the WRF runs is largely determined by the GCM predictions, the higher-resolution WRF reduces the underprediction in cyclone intensity. There is an increase in late-twenty-first-century cyclone activity over the east coast of North America in CCSM4 and its WRF, whereas there is little change in GFDL-ESM2M and WRF given that there is a larger decrease in the temperature gradient in this region. There is a future increase in relatively deep cyclones over the East Coast in the high-resolution WRF forced by CCSM4. These storms are weaker than the historical cases early in their life cycle, but then because of latent heating they rapidly develop and become stronger than the historical events. This increase does not occur in the low-resolution WRF or the high-resolution WRF forced by GFDL since the latent heat increase is relatively small. This implies that the diabatic processes during cyclogenesis may become more important in a warmer climate, and these processes may be too weak in existing coarse-resolution GCMs.
The Extent of the White Chuck Tuff, a High Temperature Pyroclastic Flow Deposit, Glacier Peak, Washington

The White Chuck Tuff, a massive deposit approximately 15 m thick, caps two terraces in the White Chuck River valley covering an area of approximately 5 km^ at the base of Glacier Peak, Washington. Three major post-glacial eruption cycles from Glacier Peak reportedly occurred approximately from 12,000 to 11,250 years ago (White Chuck Assemblage), from 5,500 to 5,100 years ago (Kennedy Creek Assemblage), and from 1,800 to 250 years ago (recent eruptions). West of Glacier Peak, pyroclastic and lahar deposits from all three episodes are found in drainages out to Puget Sound 100 km away. The White Chuck Tuff has been assumed to be approximately 11, 500 years old (Beget, 1981) and not found west of Camp Creek in the White Chuck River Valley, approximately 17 km from Glacier Peak. Anisotropy of magnetic susceptibility, paleomagnetic, petrographic, and geochemical procedures were conducted to characterize the tuff deposit. Similar laboratory procedures were conducted on five distal pyroclastic deposits to determine if they were unconsolidated runout of the White Chuck Tuff Flow direction, paleomagnetic directions and paleomagnetic poles, mineralogy, and chemical composition of the proximal indurated White Chuck Tuff indicate that it was emplaced as a single unit at temperatures exceeding 580° C. The overall flow direction during emplacement was northwesterly down the White Chuck River Valley. The paleomagnetic directions, mineral and chemical compositions are similar amongst the seven sampling sites. Five distal deposits WC-1, SR-1, SR-2, SR-3, and ST-1 were products of cold to warm (from 22°C to 375°C) debris flows that made their way down the White Chuck
Mapping Control of Erosion Rates: Comparing Model and Monitoring Data for Croplands in Northern Germany

Control of erosion rates (CER) is a key ecosystem service for soil protection. It is mandatory for sustaining the capacity, especially of agroecosystems, to provide ecosystem services. By applying an established framework to assess soil regulating services, this study compares two approaches to assess CER provision for 466 ha of cropland in Lower Saxony (Central Northern Germany). In a "sealed modelling approach", the structural and the mitigated structural impact were modelled by applying the Universal Soil Loss Equation (USLE). The second approach uses spatially explicit long-term monitoring data on soil loss rates obtained in the investigation area as an alternative to the USLE-based modelled mitigated structural impact. Assuming that the monitoring data have a higher reliability than the modelled data, the comparison of both approaches demonstrated the uncertainties of the USLE-based assessment of CER. The calculated indicators based on a sound monitoring database on soil loss rates showed that, due to limitations of the USLE model, the structural impact in thalwegs has been underestimated. Incorporating models with the ability to estimate soil loss by rilling und gullying can help to overcome this uncertainty. The produced set of complementary large-scale CER maps enables an integrated analyses of CER. In the entire investigation area, the provision of CER regulating ecosystem services was generally high, indicating good management practices. Differences at the field scale and between the different regions can be explained by variations of the structural impact and the management practices.
Beliefs and practices of physicians in Lebanon regarding promotional gifts and interactions with pharmaceutical companies.

Background Pharmaceutical companies invest greatly in promotional gifts to influence prescription of medications by physicians, yet there is limited published information evaluating its impact on healthcare. Aim This study aimed to assess the beliefs and practices of physicians in Lebanon regarding promotional gifts and their interactions with representatives of pharmaceutical companies. Methods This cross-sectional study was conducted between December 2019 and January 2020 through an email-based questionnaire sent to 5936 physicians of different specialties registered in the Lebanese Order of Physicians. Assessment was done using a validated tool and data analysis was conducted using SPSS version 26.0. Results Of the 268 respondents, 188 (70.4%) reported that physicians in Lebanon accepted gifts from representatives of pharmaceutical companies. Most of the physicians (31.7%) interacted with company representatives more than once a week. Medication samples (251 respondents) and stationary items (222 respondents) were the most common gifts accepted by physicians who admitted accepting gifts. Overall, 225 (84.9%) respondents believed that prescriptions by physicians in Lebanon were influenced by the gifts. Only 74 (40.0%) of those who accepted gifts from pharmaceutical companies believed that it was unethical, and around half did not know if the Lebanese Code of Medical Ethics allowed them to accept gifts from pharmaceutical companies. Conclusion Although physicians in Lebanon were aware of the effect that gifts from pharmaceutical companies could have on their prescription behaviours, many of them still accepted the gifts. This study provides evidence to policymakers for decision-making regarding ethical guidance on interactions between physicians and pharmaceutical companies in Lebanon.
Phenolic, Nutritional and Sensory Characteristics of Bakery Foods Formulated with Grape Pomace

The potentiality of cv. Malbec grape pomace (GP) as a functional ingredient in the formulation of bakery foods (muffins, biscuits and cereal bars) was studied. The effect of GP addition on the phenolic compounds (PCs) composition, nutritional and sensory properties were evaluated. The addition of GP increased the content of dietary fiber, proteins, ash, total phenolic content (TPC), antiradical capacity (AC), anthocyanins and non-anthocyanin PCs while decreasing the carbohydrates content. The main PCs given by the GP to supplemented foods were quercetin-3-O-glucoside, rutin, caffeic acid, syringic acid and (+)-catechin. For anthocyanins, the acylated derivatives were more stable to heat treatment (baking) in food processing which was evidenced by a higher proportion of these PCs compounds when compared to the same derivatives quantified in GP. In general, when the TPC or individual concentrations of PCs were analyzed in a nutritional or functional context, one portion of the supplemented foods showed levels high enough to satisfy the recommended dose per day of these bioactive compounds. Additionally, the foods were well received by consumers during the sensory evaluation and supplemented biscuits received the highest acceptability. This study demonstrated that GP could be a viable functional ingredient in bakery foods to incorporate components like PCs and dietary fiber into traditional consumers’ diets.
Etude du flux de soubassement sur la dynamique du sillage d'un corps non profilé à culot droit : Application du contrôle actif pour la réduction de traînée de véhicule industriel

Cette these CIFRE est le fruit d’une collaboration entre Renault Trucks et le LMFA dans la perspective d’une evaluation de la pertinence du controle actif pour la reduction de trainee de vehicule industriel. Les deux principaux objectifs de ces travaux experimentaux consistent a l’analyse de l’influence de l’ecoulement de soubassement sur la dynamique du sillage et l’etude d’une strategie de controle d’ecoulement combinant des volets deflecteurs (positionnes sur les bords superieurs et lateraux du culot) a des actionneurs de type jets pulses dans l’optique d’une reduction de la trainee aerodynamique d’un corps non profile a culot droit. Le developpement du sillage pour differentes vitesses de soubassement evoluant de 10% a plus de 80% de la vitesse de l’ecoulement infini amont est etudie sur une maquette simplifiee de vehicule poids lourd a l’echelle 1/43e. Des mesures de pression au culot permettent d’identifier quatre classes d’ecoulement associees a des structures de sillage differentes mises en evidence par des mesures PIV 2D-3C. Le sillage de la premiere classe d’ecoulement obtenu pour les tres faibles vitesses de soubassement ressemble au sillage derriere une marche 3D. Pour des vitesses de soubassement plus elevees, l’ecoulement de soubassement decolle au niveau du sol et impacte soit le culot ou soit la couche de cisaillement superieure favorisant le developpement des instabilites de type Kelvin-Helmoltz dans ce dernier cas. Enfin, la derniere classe est caracterisee par un sillage comparable a celui d’un corps d’Ahmed. L’ajout de volets deflecteurs a l’arriere du culot engendre une augmentation de la pression au culot pour l’ensemble des classes d’ecoulement. Cette augmentation reside principalement dans l’effet de vectorisation de l’ecoulement. Un systeme de controle actif est integre sur une maquette 1/8e geometriquement identique a celle a l’echelle 1/43e et equipee de volets deflecteurs. Deux angles de volet superieur sont testes afin d’obtenir en moyenne (i) un ecoulement naturel attache a la paroi du volet et (ii) un ecoulement naturel detache du volet. Par rapport au cas sans controle actif, des gains sur la trainee sont obtenus pour une certaine gamme de frequence d’actionnement uniquement dans le cas (ii). Ces gains sont obtenus suite au recollement de l’ecoulement sur le volet. Enfin, la robustesse des gains sur la pression au culot est testee avec succes en mettant la maquette en derapage pour simuler un vent de travers.
Evidence for Deep Ingression of the Midlatitude MSTID Into As Low as ~3.5° Magnetic Latitude

An observational evidence of medium‐scale traveling ionospheric disturbances (MSTIDs) reaching to magnetic latitude as low as ~3.5° over the Indian sector is provided for the first time based on OI 630‐nm airglow imaging observation from a low‐latitude station, Gadanki (13.5°N, 79.2°E; 6.6° magnetic latitude), on 12 January 2016. The horizontal wavelength, horizontal phase velocity, and period of the MSTID are found to be 160 ± 6 km, 138 ± 14 m/s, and 19.5 ± 3 min, respectively. These phase fronts are observed to move toward southwest with a propagation angle of ~235° ± 1° with respect to north. In addition to the MSTID, a strong quasiperiodic southward moving wave (QPSMW) from the evening to midnight interval and a small‐scale southward moving wave structure with wavelength and periodicity different from the QPSMW are also detected on the same night. Horizontal wavelength, horizontal phase velocity, and period of the QPSMW are estimated to be 367 ± 14 km, 131 ± 18 m/s, and 46.7 ± 13 min, respectively, and those of the small‐scale southward moving wave are found to be 157 ± 4 km, 121 ± 17.8 m/s, and 21.7 ± 3.4 min, respectively. Global Positioning System‐total electron content maps suggest that the weak and asymmetric equatorial ionization anomaly helped deep ingression of the MSTID on this night. The descent of the F layer seems to have caused the dissipation of the MSTID and QPSMW closer to the dip equator on this night. Therefore, the present investigation shows that the midlatitude MSTIDs can influence the F region plasma processes even over very low latitudes under favorable background conditions.
