Carbon filter layer for respirator derived from acrylic filter felt.

Pyrolysis emerges as a strategy for handling waste textiles, wherein the conversion of high-carbon-content textile waste into carbonaceous materials facilitates the restoration of its economic value, concurrently mitigating the environmental impact posed by textile waste. The present study fabricated carbon felts for respiratory filter layers through single-step pyrolysis of acrylic filter felts. The advantage of employing conductive carbon felt as a respiratory filter layer is its capability to concurrently serve two functions: filtration and electrical heating for high-temperature disinfection.

A Novel Membrane-Associated Protein Aids Bacterial Colonization of Maize.

The soil environment affected by plant roots and their exudates, termed the rhizosphere, significantly impacts crop health and is an attractive target for engineering desirable agricultural traits. Engineering microbes in the rhizosphere is one approach to improving crop yields that directly minimizes the number of genetic modifications made to plants. Soil microbes have the potential to assist with nutrient acquisition, heat tolerance, and drought response if they can persist in the rhizosphere in the correct numbers.

Effect of Drying Methods on the Thermal and Mechanical Behavior of Bacterial Cellulose Aerogel.

Bacterial cellulose (BC) presents significant promise as a biomaterial, boasting unique qualities such as exceptional cellulose purity, robust mechanical strength, heightened crystalline structure, and biodegradability. Several studies have highlighted specific effects, such as the impact of dehydration/rehydration on BC tensile strength, the influence of polymer treatment methods on mechanical properties, the correlation between microorganism type, drying method, and Young's modulus value, and the relationship between culture medium composition, pH, and crystallinity. Drying methods are crucial to the structure, performance, and application of BC films.

Home range, habitat use and capture-release of translocated leopards in Gir landscape, Gujarat, India.

Understanding the spatial ecology of translocated leopards (Panthera pardus fusca) is crucial for their conservation and the effective assessment of conflict management strategies. We investigated the home range and habitat preferences of five radio-collared leopards (n = 5; 2 males; 3 females) in the Gir landscape. Additionally, we examined the usefulness of the capture-release strategy for these animals.

Expanding the synthetic biology toolbox of Cupriavidus necator for establishing fatty acid production.

The Gram-negative betaproteobacterium Cupriavidus necator is a chemolithotroph that can convert carbon dioxide into biomass. Cupriavidus necator has been engineered to produce a variety of high-value chemicals in the past. However, there is still a lack of a well-characterized toolbox for gene expression and genome engineering.

Salary Disparities in Public Health Occupations: Analysis of Federal Data, 2021‒2022.

To assess salary differences between workers within key public health occupations in local or state government and workers in the same occupations in the private sector. We used the US Department of Labor's Occupational Employment and Wage Survey (OEWS). Referencing previous studies matching Standard Occupational Classification (SOC) codes with health department occupations, we selected 44 SOC codes.

Incorporation of Cellulose-Based Aerogels into Textile Structures.

Given their exceptional attributes, aerogels are viewed as a material with immense potential. Being a natural polymer, cellulose offers the advantage of being both replenishable and capable of breaking down naturally. Cellulose-derived aerogels encompass the replenish ability, biocompatible nature, and ability to degrade naturally inherent in cellulose, along with additional benefits like minimal weight, extensive porosity, and expansive specific surface area.

Standard Occupational Classification Codes: Gaps in Federal Data on the Public Health Workforce.

To determine whether US Department of Labor standard occupational classification (SOC) codes can be used for public health workforce research. We reviewed past attempts at SOC matching for public health occupations and then used the National Institute for Occupational Safety and Health Industry and Occupation Computerized Coding System (NIOCCS) to match the actual job titles for 26 516 respondents to the 2021 Public Health Workforce Interests and Needs Survey (PH WINS) with SOC codes, grouped by respondents' choice of job category in PH WINS. We assessed the accuracy of the NIOCCS matches and excluded matches under a cutpoint using the Youden Index.

Synthetic Biology Toolbox for Nitrogen-Fixing Soil Microbes.

The soil environment adjacent to plant roots, termed the rhizosphere, is home to a wide variety of microorganisms that can significantly affect the physiology of nearby plants. Microbes in the rhizosphere can provide nutrients, secrete signaling compounds, and inhibit pathogens. These processes could be manipulated with synthetic biology to enhance the agricultural performance of crops grown for food, energy, or environmental remediation, if methods can be implemented in these nonmodel microbes.

Scripting a new dialogue between diazotrophs and crops.

Diazotrophs are bacteria and archaea that can reduce atmospheric dinitrogen (N) into ammonium. Plant-diazotroph interactions have been explored for over a century as a nitrogen (N) source for crops to improve agricultural productivity and sustainability. This scientific quest has generated much information about the molecular mechanisms underlying the function, assembly, and regulation of nitrogenase, ammonium assimilation, and plant-diazotroph interactions.

Sandwich Fibrous PEG Encapsulations for Thermal Energy Storage.

Phase change materials (PCMs) textiles have been developed for personal thermal management (PTM) while limited loading amount of PCMs in textiles reduced thermal buffering effect. In this work, we proposed a sandwich fibrous encapsulation to store polyethylene glycol (PEG) with PEG loading amount of 45 wt %, which consisted of polyester (PET) fabrics with hydrophobic coating as protection layers, polyurethane (PU) nanofibrous membranes as barrier layers and PEG-loaded viscose fabric as a PCM-loaded layer. The leakage was totally avoided by controlling weak interfacial adhesion between protection layer and melting PEG.

In this paper, copper deposited graphene was fabricated through electroless plating. A novel and facile pretreatment method is introduced based on ultrasonic treatment with nickel nano-particles as the catalytic core. This method abandons the sensitization and activation process in the traditional pretreatment that reduces the time and economic cost dramatically.

Living on the sea-coast: ranging and habitat distribution of Asiatic lions.

Endangered Asiatic lions (Panthera leo persica) are renowned for their resilience and as a flagship of successful conservation and management. Lions dispersing out of the Gir forest have established themselves in the coastal habitats for about 25 years. We propose that the home range and spatial distribution of lions inhabiting the coastal habitats would be distinct from the forested habitats of the protected area.
