A novel [email protected] photocatalyst, which was generated using the metal organic framework ZIF-8 and intact chloroplasts (CHs) from Chlorella sp. in a one-pot synthesis, was used in this study for the first time to degrade tetracycline hydrochloride (TCH) through photocatalysis. The results of systematic characterization demonstrated that [email protected] was successfully p0repared. Meanwhile, [email protected] exhibited excellent photocatalytic performance and good adaptability. Under the condition of simulated sunlight, the high porosity ZIF-8 shell enabled CHs to maintain typical photosynthetic oxygen evolution behavior in vitro, and using CHs as the core produced significant ROS, significantly improving the efficiency of TCH photocatalytic degradation. In addition, the radical trapping test and EPR spectra proved that O 2 – , 1 O 2 , and •OH were the key active species for TCH degradation. Eventually, the [email protected] system can not only expand the new concept of organic pollutant degradation in water bodies, but also offer recommendations for live organ envelope modification..

Organophosphate flame retardants (OPFRs) are extensively used as flame retardants and plasticizers and have drawn concern due to their endocrine disruptive potentials. However, the impacts of OPFR exposure on reproductive and thyroid hormones have not been well clarified for females. In this study, serum concentrations of OPFRs were investigated, and levels of reproductive and thyroid hormones, including follicle-stimulating hormone (FSH), luteinizing hormone, estradiol, anti-Müllerian hormone, prolactin (PRL), testosterone (T), and thyroid stimulating hormone, were analyzed in childbearing-age females from Tianjin, a coastal city in China (n=319). Tris(2-chloroethyl) phosphate (TCEP) was the predominant OPFR and the median concentration was 0.33 ng/mL with a detection frequency of 96.6%. In the whole population, tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) and tris(2-chloroisopropyl) phosphate (TCIPP) were positively associated with T (p30, p © 2023, The Authors.

The distribution of specific tree species and single tree information can shift down the research scale of geography and ecology, bridging research from regional to local scales. However, efficiently and finely extracting the spatial distribution and single tree information for a tree species regionally has always been a challenge due to the constraints of data and algorithms. With sub-meter visible light satellite images (RGB bands) in 2021 to 2022, we constructed a novel method for extracting the spatial distribution and single tree information of oil palm across Malaysia, namely the Single Tree Extraction Method - Oil Palm (STEM-OP). We developed a graphic morphological algorithm based on gradient difference window detection to extract the spatial distribution of oil palms. Then, we proposed an algorithm of double ring sliding detection algorithm to identify the canopy texture features of single oil palm. Finally, an adaptive iterative erosion algorithm was employed to separate overlapping and adjacent canopies into single trees. The overall accuracy of both the spatial distribution and number of single oil palm extracted by STEM-OP exceeded 90%. Our study revealed that the total area of oil palm in Malaysia was 5.25 million hectares, with a total of 572.6 million trees and an average planting density of 109 palms per hectare. The STEM-OP addresses the computational inefficiencies of methods with training samples and limitations of satellite image bands. For the first time, our study extracts the refined spatial distribution of oil palm and obtains the planting density and single tree position on a national scale. All of these are of great value to the formulation of oil palm development policies and ecological protection measures. © 2024, The Authors. All rights reserved.

Plastic film mulching (PM), which contributes to nearly half of the increased crop yields in dryland agroecosystems, exacerbates environmental burdens due to its non-degradable nature. Globally, there is a growing demand to replace non-degradable PM with degradable film mulching (DM), yet its impacts on soil organic carbon (SOC) in dryland agroecosystems remains unknown. Here, using multi-field studies and mesocosm experiments, we found that DM strongly increased but PM reduced SOC storage (0-1 m). This difference is likely attributable to the higher microbial C use efficiency in soil under DM, leading to increased microbial-derived C compared to PM. Under the high roading scenario for 2100, DM could reduce the decomposition of SOC (0-1 m) in China's drylands by 9.0 ± 1.0 Mg ha year (one standard error) compared with PM. Our findings highlight that DM is a promising alternative to PM for sequestrating SOC and alleviating C loss under climate change in dryland agroecosystems.

Hemicellulose in Oil Palm Empty Fruit Bunches (EFB) can be hydrolyzed to xylose and then converted to furfural via dehydration. Generally, furfural production uses sulfuric acid as a solvent. However, this solvent has toxic and can cause corrosion in equipment. This study developed a furfural production process using a green solvent called deep eutectic solvent (DES). DES was synthesized by mixing choline chloride and oxalic acid with a mole ratio of 1:1. The temperature and processing time were varied at 100, 120, and 150oC, respectively, to obtain optimal furfural. The optimal furfural concentration was reached 7.72 g/l at 150oC for 30 minutes. This process can be an alternative environmentally friendly furfural production process.

This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE technology for Ships Program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.

Reassessing the impact of social media on healthcare delivery: insights from a less digitalized economy

Social media plays a crucial role in modern healthcare by promoting patient engagement, facilitating communication among professionals, and serving as a platform for health education and outreach. Its significance in healthcare delivery continues to grow as digital communication becomes increasingly integral to the industry’s efforts to improve healthcare outcomes. Nonetheless, existing studies have not adequately and empirically explored its impact in less digitalized economies. Thus, this study seeks to investigate the impact of social media on healthcare delivery systems in a less digitalized economic context. Leveraging the social media engagement theory, the study employs a partial least squares (PLS-SEM) approach to explore the impact of social media in Ghana’s healthcare system. Based on a purposely selected sample of 457 healthcare professionals from Ghana, the study found that using social media for crisis management, patient-doctor relationships, and information dissemination positively impacts healthcare systems. On the contrary, social media use for public relations activities did not have any significant impact on healthcare delivery. This study contributes to the growing literature on the affordances of social media in the circular economy towards improved healthcare delivery in emerging economies. The study offers a strategy for optimizing the use of social media within healthcare settings to foster enhanced healthcare outcomes, particularly a less digitalized economies.
