Background: Dust generated during the processing of building materials enterprises can pose a serious health risk. The study aimed to compare and analyze the results of ART and the Monte Carlo model for the dust exposure assessment in building materials enterprises, to derive the application scope of the two models.
Methods: First, ART and the Monte Carlo model were used to assess the exposure to dust in each of the 15 building materials enterprises. Then, a comparative analysis of the exposure assessment results was conducted. Finally, the model factors were analyzed using correlation analysis and the scope of application of the models was determined.
Results: The results show that ART is mainly influenced by four factors, namely, localized controls, segregation, dispersion, surface contamination, and fugitive emissions, and applies to scenarios where the workplace information of the building materials enterprises is specific and the average dust concentration is greater than or equal to 1.5 mg/m. The Monte Carlo model is mainly influenced by the dust concentration in the workplace of building materials enterprises and is suitable for scenarios where the dust concentration in the workplace of the building materials enterprises is relatively uniform and the average dust concentration is less than or equal to 6mg/m.
Conclusion: ART is most accurate when workplace information is specific and average dust concentration is > 1.5 mg/m; whereas, The Monte Carlo model is the best when dust concentration is homogeneous and average dust concentration is < 6 mg/m.

Semiconductor magic-sized nanoclusters (MSCs) possess atomic-level compositional precision and ultrasmall dimensions, allowing accurate modulation of electrochemiluminescence (ECL) properties, essential for advanced bioanalytical applications. However, low intrinsic ECL intensity and poor stability in bipolar electrode (BPE)-ECL systems hinder their broader use. In this work, we addressed these limitations through doping and direct optical crosslinking strategies, achieving a 24-fold boost in the ECL signal and a fivefold stability increase for doped (CdS):Ag MSCs compared with original (CdS) MSCs.

Magnetic refrigeration leads the current commercialization efforts of ambient caloric cooling technologies, is considered among its peers most promising in terms of anticipated energy efficiency gain, and allows for complete elimination of harmful coolants. By now, functional magnetocaloric components (so-called regenerators) based on Mn-substituted and hydrogenated LaFeSi alloys are commercially available. However, this alloy system exhibits magnetostriction, is susceptible to fracture, oxidation, and does not passivate well, rendering it prone to failure and corrosion, particularly when using water as favorable heat exchange medium.

With the increasing demand on high-density integration and better performance of micro-nano optoelectronic devices, the operation temperatures are expected to significantly increase under some extreme conditions, posing a risk of degradation to metal-based micro-/nano-structured metasurfaces due to their low tolerance to high temperature. Therefore, it is urgent to find new materials with high-conductivity and excellent high-temperature resistance to replace traditional micro-nano metal structures. Herein, we have proposed and fabricated a thermally stable graphene assembly film (GAF), which is calcined at ultra-high temperature (~ 3000 ℃) during the reduction of graphite oxide (GO).

Formamidopyrimidine DNA glycosylase (Fpg) and flap endonuclease 1 (FEN1) are essential to sustaining genomic stability and integrity, while the abnormal activities of Fpg and FEN1 may lead to various diseases and cancers. The development of simple methods for simultaneously monitoring Fpg and FEN1 is highly desirable. Herein, we construct a multiple cyclic ligation-promoted exponential recombinase polymerase amplification (RPA) platform for sensitive and simultaneous monitoring of Fpg and FEN1 in cells and clinical tissues.

When evaluating reproductive care for lesbian, gay, bisexual, transgender, and queer+ patients, there are multiple factors that must be addressed from a clinician, clinic, and social standpoint. Clinicians should be trained in culturally humble and trauma-informed care; clinics should have intake forms that identify sexual orientation, gender identity, and pronouns. The clinic environment should be inclusive, with all gender or single-stall bathrooms, and patient-facing educational materials that are representative of individuals with diverse partnerships, races, and ethnicities.
