Published: February 2025

AbstractRheology, the study of flow and deformation in materials, is key to understanding the flow behavior of fresh cementitious materials, which, in turn, influences their hardened properties and durability. The rheology of cementitious mixes is complex and significantly impacts their fresh‐state application in construction. Understanding and controlling the factors affecting rheology is crucial for optimizing mix designs and improving construction practices. This study provides an in‐depth understanding of cementitious mix rheology, factors influencing rheology, optimization, and its correlation with mathematical models. The paper presents the impact of internal factors, such as water–cement ratio and cement fineness, as well as external factors, like temperature, shear rate, and time, on the rheology of cementitious materials. The study examines how these factors influence fundamental rheological characteristics and behaviors such as thixotropy and shear thinning. It outlines ways to optimize mix designs, enhance workability, and improve emerging technologies like 3D concrete printing. Additionally, it correlates available mathematical models with the identified influencing factors. This analysis fills a gap in existing literature and contributes to advancing concrete technology and its practical applications, paving the way for innovative solutions in the construction industry. It also provides directions for future research in rheological behavior modeling, potentially leading to more efficient and sustainable concrete construction practices.

Published: February 2025

AbstractViolet light, a component of sunlight, is critical for human health, but it is usually ignored in classic white light‐emitting diodes (LEDs) that are fabricated by pumping green, yellow, or red phosphors by blue LEDs. To realized full‐spectrum white LEDs for healthy lighting, it is required to replace blue LEDs by near‐ultraviolet (n‐UV) or violet LEDs to pump multi‐color phosphors. Herein, we reported blue and/or blue–violet phosphors of Na3KMg7P6O24:Eu2+ (NKMPO:Eu2+) and Na3K1–ySryMg7–yLiyP6O24:Eu2+ (NKSMLPO:Eu2+) that can be efficiently excited by n‐UV and violet LEDs. The NKSMLPO:Eu2+ phosphor (y = 0.1), showing a small thermal quenching, had a photoluminescence quantum yield of 64.9% and 41.2% under 365 and 405 nm excitation, respectively. Full‐spectrum white LEDs were obtained by combining n‐UV or violet LEDs with the blue/blue–violet‐emitting NKSMLPO:Eu2+ and other commercial phosphors, which show a correlated color temperature of 4285–4705 K and a maximal color rendering index of 98.4. It confirms that the NKSMLPO:Eu2+ phosphors can be adopted as a violet light filler for producing sunlight‐like white LEDs.

Published: February 2025

AbstractLaser 3D printing technology offers significant benefits in fabricating silicon carbide (SiC) ceramics, largely due to its support‐free structure and simplified construction process. However, the produced green parts exhibit considerable porosity and decreased strength, rendering them susceptible to damage during powder removal and subsequent processing stages. This vulnerability significantly hinders the practical applications of laser 3D‐printed SiC ceramics. This study introduced the use of epoxy resin–phenolic resin dual binders in the laser 3D printing of SiC ceramics, with the aim of improving the integrity and performance of both the green and debinded parts, as well as the final SiC ceramics. The highest strength of the SiC green part, with a 5 vol% addition of epoxy resin, reached 6.82 ± 0.38 MPa, while the strength of the densified SiC ceramic was enhanced to 240 ± 5 MPa.

AbstractOxides with perovskite structures have received extensive research attention due to their fascinating physical properties. In this study, polycrystalline ceramics of La0.67Ca0.25‐xSr0.08AgxMnO3 (LCSAMO, x = 0.06, 0.08, 0.10, and 0.12) were obtained by changing the previous sol‐gel preparation process parameters. The results show that LCSAMO ceramics are orthogonal perovskite structures with a space group of Pnma. With increasing x, the grain size, lattice constants, Mn‐O bond length (dMn‐O), and Mn‐O‐Mn bond Angle (θMn‐O‐Mn) are slightly affected. When x = 0.08, the average grain size achieved a maximum value of 8.84 µm, which enhanced the intergranular connectivity. The Mn4+/(Mn3++Mn4+) ratio was the maximum value of 30.26% when x = 0.08, where the double exchange (DE) mechanism was the strongest among the four samples and optimized the electrical transport properties. Ag doping induces distortion in MnO6 octahedron. The electrical transport properties of the ceramics were improved by the combined effect of the distortion and DE mechanism. The temperature coefficient of resistivity (TCR) achieved the maximum value of 24.07% K−1 at 284.91 K. The results of this work provide a theoretical basis for Ag doping at the A‐site and thus obtaining lanthanide perovskite manganese oxide with high TCR.

ABSTRACTAimThis study aims to evaluate the biogeographical and ecological patterns associated with the diversification and distribution of Alouatta species, commonly known as howler monkeys. Our research provides valuable insights into the comprehension of the evolutionary history of this genus.LocalNeotropical region.Time PeriodLast 13 Mya.Major Taxa Studied11 species of Alouatta.MethodsA dataset including 32 nuclear and mitochondrial genes was employed to reconstruct a dated maximum composite phylogenetic tree. Contemporary biodiversity data were employed in the context of this phylogenetic tree to reconstruct ancestral distribution and to infer the main speciation mechanisms. Niche evolution tests were performed for different bioclimatic and topographic variables to access patterns of niche divergence or niche conservatism.ResultsThe diversification of Alouatta seems to have started ~13 Mya, probably near the Northwestern Amazon, and appears to have been driven mostly by niche divergence in parapatry. Despite this, niche conservatism or convergence led to significant overlap in ecological niches between some species, particularly those representing the early divergences of both South American clades.Main ConclusionsThe parapatric distribution presented by several pairs of Alouatta species generally evolved through environmental niche divergence driven by dispersal. The conservation or convergence of some niche traits is correlated with some secondary contacts, which may be increasing due to habitat loss. Niche conservation patterns found for some climatic variables highlight the susceptibility of the genus to climate change.

Possible Limitations in the Management of a Small Ant Pest Species (Plagiolepis alluaudi) Using Gel Baits

Published: February 2025

ABSTRACTAlluaud's little yellow ant, Plagiolepis alluaudi Emery 1894, (Hymenoptera: Formicidae), is an emerging nuisance species in floriculture and residential areas around the globe. Originally described from Madagascar, it ranks among the smallest widespread formicine pests. To date, no evaluations of management protocols for this species have been reported. In ants, feeding preference is related to ant body size and viscosity and nutritional content of the food source. Optimizing these factors could lead to improved bait performance. To assess population management implications of various bait parameters on a small pest ant species, four commercial ant baits of varying viscosities, active ingredient (AI) group and concentration, and nutritional content were evaluated in laboratory and field assays against P. alluaudi. All four products negatively affected P. alluaudi survival compared to the untreated control, and all products were associated with greater visitation compared to the control, suggesting all AIs tested are viable candidates for P. alluaudi management. However, their direct use for population management in the field may be limited, as feeding cessation was eventually observed on all four baits. When baits were diluted with water, viscosity was reduced and survival was initially higher compared to with undiluted baits. However, similarly low levels of survival were maintained over time. Most importantly, we found in a 2‐year observational field study involving sustained baiting within an infested structure that only the bait formulation with the lowest overall viscosity was able to alleviate P. alluaudi nuisance indoors. Our results suggest that diluting baits may be a viable strategy for targeting very small pest ant species, and the greater time to lethality of diluted baits, resulting from reduced toxicant concentration, may be a reasonable trade‐off allowing smaller ant species to continue feeding for a sufficient duration on a bait formulation.

Published: February 2025

ABSTRACTObjectiveTo address the following PICOS question: Can single‐shade resin composites achieve a color match comparable to multi‐shade composites in tooth restoration?Materials and MethodsA comprehensive search was conducted across multiple electronic databases to identify in vitro and clinical studies evaluating the color match in tooth restoration, in terms of CIELAB (ΔEab) and/or CIEDE2000 (ΔE00) color differences metrics, using single‐shade and multi‐shade composites. The risk of bias was assessed using the Quality Assessment Tool For In Vitro Studies (QUIN Tool), while the revised Cochrane Collaboration's tool (RoB 2) was employed for randomized controlled clinical trials (RCTs). Meta‐analyses were performed using RevMan to compare ΔEab and ΔE00 values between single‐shade and multi‐shade composites (p < 0.05).ResultsAfter initial screening, 15 in vitro studies and 4 RCTs met the inclusion criteria for qualitative synthesis, with 8 in vitro studies selected for quantitative analysis. The majority of in vitro studies were classified as medium risk of bias, while RCTs were ranked as low risk of bias. Meta‐analyses performed on in vitro studies revealed that single‐shade composites exhibited statistically significant higher color differences with the surrounding tooth structure compared to multi‐shade composites, for both ΔEab and ΔE00 (p < 0.05). However, RCTs usually reported promising outcomes for single‐shade materials.ConclusionsThis systematic review concluded that multi‐shade composites provide a more accurate color match between tooth and direct restoration than single‐shade materials when evaluated by instrumental analysis in laboratory settings.Clinical SignificanceMulti‐shade composites exhibit superior color match properties in laboratory studies. However, single‐shade composites are a promising alternative when observed visually in clinical settings.

Published: February 2025

ABSTRACTObjectivesTo evaluate the feasibility of esthetic assessments based on intraoral scanning data using pink and white esthetic scores (PES/WES).Materials and MethodsThirty samples with both intraoral photographs and scanning data were collected and rated by two observers with excellent consistency independently. PES includes seven variables, and WES includes five. The maximum scores were 14 and 10, respectively.ResultsThe mean PES/WES was 10.60 ± 1.69 and 8.50 ± 1.28 for photographs and 10.97 ± 1.69 and 8.40 ± 1.25 for scanning data. No significant difference was observed between the two sample types. The alveolar process variable had significantly higher scores, while the soft‐tissue color variable had significantly lower scores based on intraoral photographs compared to scanning.ConclusionsIntraoral scanning could be a method for the esthetic evaluation of single implant‐supported restorations using PES/WES. The use of three‐dimensional imaging enables the precise assessment of esthetic outcomes, paving the way for improvements in the digital workflow of implant dentistry. However, the limitations of color and texture reproducibility should be noted.Clinical SignificanceIntraoral scanning data can be used for esthetic evaluation, and reliable results could be achieved with the application of scanning.

Published: February 2025

ABSTRACTNile tilapia (Oreochromis niloticus) is an important food source worldwide and plays a significant role in Mexico's aquaculture industry. However, it faces increasing challenges from disease outbreaks threatening this sector. From recent research and epidemiological data, this review examines the diseases impacting tilapia aquaculture in Mexico. It analyses bacterial, parasitic, viral, and fungal infections, providing insights into their clinical signs, etiological agents, treatment strategies, and geographical distribution across various Mexican states. The study highlights four major parasitic infections: Cichlidogyrus Infection, Gyrodactyliasis, Neobenedeniosis and Trichodiniasis. Six prominent bacterial infections are discussed, including motile Aeromonas septicaemia (MAS), Streptococcosis, Staphylococcosis, Francisellosis, Edwardsiellosis and Mycobacteriosis. It addresses Saprolegniasis, a fungal infection affecting tilapia eggs and the overall health of hatcheries. Additionally, it highlights technical information on the Tilapia Lake Virus (TiLV), which poses a significant viral threat. This analysis examines the three‐level diagnostic system for infectious diseases in aquaculture outlined by the FAO, emphasising its application in tilapia aquaculture in Mexico. The system includes (i) implementing prevention strategies, biosecurity protocols and good management practices (Level I); (ii) conducting laboratory‐based diagnostic tests (Level II); and (iii) utilising advanced molecular techniques for early disease detection (Level III). By adopting these measures, the aquaculture sector can effectively mitigate disease outbreaks, thereby promoting the sustainable growth and long‐term success of tilapia farming in Mexico.

BackgroundUnintentional overdose is the leading cause of pregnancy‐associated death in Maryland and is preventable. Stigma contributes to birthing peoples’ disengagement with the health care system, and health care professionals may participate in stigmatizing processes. We aimed to develop and evaluate a training on stigma and bias related to substance use disorder (SUD) for maternal health care professionals in Maryland.MethodsWe used a community‐engaged process to develop a training on stigma and bias related to SUD in pregnancy and implemented it with Maryland maternal health care professionals employed in birth hospital settings. We conducted a multimethod pre‐post training evaluation, using a quantitative analysis of implementation reach, a pre‐post knowledge test, a satisfaction survey, and a qualitative analysis of hospital facilitation meeting logs.ResultsThe training was completed by 1145 health care professionals. Knowledge test scores increased significantly after training, with the greatest change noted in the safety of medications for opioid use disorder during pregnancy. Over 90% of participants found the training relevant and planned to actively use what they learned. Qualitative feedback indicated the training may increase empathy with the patient population and contribute to practice changes.DiscussionOur evaluation suggests that this training is valuable, effective at increasing knowledge, and a potential catalyst for practice change among health care professionals working with pregnant and postpartum patients with SUD.

AbstractUnderwater structural inspection is essential for ensuring the safety and longevity of bridges. To improve the efficiency and accuracy of these inspections, this paper presents a method for measuring the morphology of bridge piers through refraction correction and multi‐camera calibration. Using an underwater visual inspection platform with appropriate lighting, the measurement equipment mitigates low visibility challenges. A coplanar camera refraction parameter calibration method based on encoded markers is proposed to reduce the effects of refraction, along with the development of a multi‐refraction correction model. Additionally, a novel multi‐camera extrinsic calibration method is introduced to stitch point clouds. A comparative analysis of the two extrinsic calibration methods, conducted both in air and underwater, has been performed to validate the accuracy and efficiency of the proposed approach. Finally, the circular cross‐section shape of the underwater bridge pier was successfully measured, and the results of defect localization were effectively presented.

Published: February 2025

ABSTRACTObjectiveTo compare head posture and upper spine morphology in hypermobile Ehlers‐Danlos syndrome (hEDS) patients with healthy controls with neutral occlusion.Materials and MethodsThe study consisted of 27 hEDS patients (23 females, 4 males, mean age 36.41 ± 11.35) and 39 healthy controls (28 females, 11 males, mean age 31.85 ± 11.35) with neutral occlusion and no previous orthodontic treatment. Head posture was analysed by angular measurements on lateral cephalograms taken in natural head position and upper spine morphology was assessed on Cone Beam Computed Tomography (CBCT) by visual analysis of fusion and partial cleft of the upper spine and compared by general linear and logistic analyses adjusted for age and gender.ResultsIn total, upper spine morphological deviations occurred significantly more often in hEDS patients (51.9%) compared to controls (15.4%) (p = 0.007). Out of the two categories of upper spine morphological deviations (fusion anomalies and posterior arch deficiencies (PAD)), PAD occurred significantly more often in hEDS patients (48.1%) compared to controls (12.8%) (p = 0.007). The differences remained significant when p‐values were corrected for multiple testing comparing groups. Head posture was almost significantly more extended in hEDS patients compared to controls when the p‐values were corrected for multiple testing comparing groups (NSL/VER, p = 0.089; NSL/OPT, p = 0.080).ConclusionsThe results of the present study indicate that upper spine morphology is affected in hEDS patients. The results may contribute to a further understanding of the spinal phenotypic spectrum in hEDS patients and thus prove valuable in the diagnostics and treatment of hEDS patients.
