In this study, a facile polypiperazine-amide (PPA) composite nanofiltration (NF) membrane with nanomaterial graphene oxide (GO) incorporated into polyamide (PA) layer for high water flux and anti-fouling was fabricated by interfacial polymerization (IP). The chemical composition, structure surface properties of the PPA/GO PPA NF membranes were characterized FTIR, XPS, FE-SEM, AFM, zeta-potential contact angle measurements. separation ability investigated discussed. experimental results...

Daylily is a functional food with high nutritional value in China. Datong (DT) Shanxi Province one of the four main production areas daylily. Therefore, Linfen (LF), Lvliang (LL), and Yangquan (YQ) have also introduced daylily from DT. However, geographical climatic conditions producing patterns cause variations quality. In present study, we found that nutrient composition daylilies different varied. The key environmental factors affecting nutrition regions were altitude temperature. widely...

The health behaviors and blood pressure control of patients with hypertension who have had a stroke are unsatisfactory. A protocol comprehensive reminder system has been published, the results 3 months implementation demonstrated improved patient control. continuity intervention effect on these variables after was not clear.The aim this study to determine impact behaviors, medication adherence, pressure, disability, recurrence in from baseline 6 discharge.A multicenter, assessor-blinded,...

Using longitudinal survey data from women in the CRA-W Graduate Cohort program, we measured prevalence of observed or experienced sexism and its impact on departure Computer Science Engineering (CSE) doctoral programs. Our suggest that sexist behavior is perceived less often by these than it general. In addition, few who observe are motivated to think leaving their CSE Nevertheless, when reason for thinking due they experienced, odds actually departing at least 21 times greater if thought...

There is a lack of stable and hydrophobic OSN membranes meaning that their implementation in non-polar solvent nanofiltration remains challenge. PDMS–PTFPMS (fluoropolymer) offers an alternative membrane material relevant applications.

Landslides occur frequently in Lixian County, China, and land use has changed significantly recent decades. We obtained data for the years 1980, 2000, 2018, as well three landslide susceptibility maps from a Random Forest model. Agricultural land, low coverage grassland, water area, urban, rural other construction were prone to landslides. Landslide was areas of woodland, moderate high bare rock desert tundra. Areas with mainly located catchment study region, 2.61% decrease over 38-year...

In order to quickly and accurately detect immature grape clusters in the complex environment of orchard, a new model FCAE-YOLOv8n was proposed with low hardware requirements, high target accuracy fast convergence. The improved based on original YOLOv8n model. Firstly, possessed numerous parameters unsuitable for mobile terminal deployment. Faster Block module used replace Bottleneck C2f, which reduced parameters. Secondly, similarly-colored backgrounds, small-sized grains, mutual occlusion...

As a representative city located in the Loess Plateau region of China, Lanzhou is affected by various environmental and engineering factors, such as precipitation, earthquake subsidence, building construction, which all lead to frequent geological disasters. Obtaining information on land subsidence over long time series helps us grasp patterns change types ground hazard. In this paper, we present results using Interferometric Synthetic Aperture Radar (InSAR) monitor main urban area from 26...

The research reported here confirms and deepens our understanding of factors that affect women's confidence in their ability to complete a computer science or engineering (CSE) doctoral degree. Analysis data from longitudinal study women participating the Computing Research Association's Graduate Cohort for Women identifies conditions experiences perceive as influential. More importantly, we found who are not confident programs about four times more likely think leaving CSE than those begin...

Background Risk factor management via behavioral change contributes substantially to secondary stroke prevention. The health belief model identified self-perceived risk as a significant in behavior change. In previous studies, people have tended incorrectly estimate their of stroke. Little is known about the differences knowledge and behaviors patients who had with different risks recurrence China. Objective aims this study were determine accuracy compare hypertensive at strata. Methods...

Germination in sesame seeds (Sesamum indicum L.) water and indole-3-acetic acid (IAA) solution is investigated with magic-angle-spinning (MAS) solid state nuclear magnetic resonance (NMR) spectroscopy, supplemented by liquid NMR spectroscopy. The spectra show good resolution can be assigned sufficient confidence. characteristic spectral peaks relaxation rates were monitored during the entire course of germination for better understanding biophysical biochemical mechanisms involved triphasic...

Molecular dynamics (MD) simulation was used to study the structural and diffusive properties of zeolitic imidazolate framework-8 (ZIF-8)/polydimethylsiloxane (PDMS), a novel alcohol-permselective mixed matrix membrane (MMM). Simulation models one pure PDMS three ZIF-8/PDMS MMMs with increasing loadings were successfully constructed. Non-bond energy turned out be strong attractive interaction between ZIF-8 cells. The morphology mobility chains characterized by mean square displacement (MSD)....

Due to the casualties and economic losses that can be caused by building collapse after an earthquake, damage assessment is a very important part of earthquake disaster evaluation. As result advantages polarimetric synthetic aperture radar (PolSAR) imaging, both accuracy speed guaranteed in process identification using single post-earthquake PolSAR image. The number collapsed buildings usually overestimated when adopting traditional method, which because scattering mechanism similar intact...

Unprecedented high resolution 7Li solid state NMR spectra establish a relationship between lithium chemical shift and the size of nanopores in Nafion, state-of-the-art proton exchange membrane widely used fuel cells batteries. This information provides most direct unambiguous characterization offers exceptional insights into performance this (PEM) points out approaches to improving it, or finding substitute material, future.
