Low‐Voltage Pulsed GMA‐AM Application for Controlling Heat Input and Improving Deposition Quality of 309LSi Multilayered Structures

steel research international, EarlyView.
This manuscript presents a study on the effects of parameter control of low‐voltage pulsed‐GMA‐AM application for producing 309LSi multilayered build‐ups, which can simultaneously lead to reduced heat input up to 32.1%, enable pulsed‐spray transfer, provide stable depositing conditions and preserve dimensional consistency, favoring fabrication of a 114‐

Experimental assessment of column rectangularity in flat‐slab slab–column connections

Structural Concrete, EarlyView.
Abstract This paper presents an experimental investigation of the punching shear behavior of seven 3.00 m × 3.00 m × 0.20 m flat slabs without shear reinforcement, supported by internal rectangular columns. The column side lengths were varied to obtain aspect ratios, cmax/cmin, from 1.67 to 4.00, while the flexural reinforcement and overall slab ...

Synergistic Toxicity of Low‐Concentration Metal Mixture on Male Rats: Reproductive, Renal, and Hepatic Effects

Environmental Toxicology, EarlyView.
ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

Trace Levels of Triclosan May Affect Root Growth and Morphology in Cultivated Plants

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) is a micropollutant frequently detected in biosolids applied to agricultural soils. In soil solution—where it is potentially bioavailable to roots—it occurs at residual concentrations (ng L−1). Nevertheless, the ecotoxicological implications of TCS exposure in agricultural crops at these concentrations are still not fully ...

Embryotoxic Effects of Monosodium Methyl Arsenate (MSMA) on Gallus gallus: Morphological and Morphometric Evidence of Developmental Disruptions

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities and the large volume of compounds released into the environment are sources of contamination for plants, animals, and humans. The herbicide monosodium methyl arsenate (MSMA) ranks among the best‐selling agricultural pesticides in Brazil.

Drug‐Induced Sleep Endoscopy in Children Predicts OSA Severity

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background While adenotonsillectomy (AT) is first line for pediatric obstructive sleep apnea (OSA), treatment failure is common. Drug‐induced sleep endoscopy (DISE) provides dynamic airway assessment, but its role in predicting OSA severity requires clarification. This study correlates DISE findings with polysomnographic severity. Objective To

Testicular Echobiometry and Sperm Characterization in Oncilla (Leopardus tigrinus) From the Caatinga Biome

Zoo Biology, EarlyView.
We describe testicular echobiometry and sperm characterization in oncilla (Leopardus tigrinus) from the Caatinga biome, Ceará, Brazil. ABSTRACT Among neotropical small felids, the Leopardus tigrinus is classified as vulnerable by the International Union for Conservation of Nature, but studies on reproductive morphology and physiology are scarce for ...
