Preparation and application of halogen-free and efficient Si/P/N-containing flame retardants on cotton fabrics.

Cotton fabric is extensively utilized due to its numerous applications, but the flammability associated with cotton fabric poses potential security risks to individuals. A halogen-free efficient flame retardant named poly [(tetramethylcyclosiloxyl spirocyclic pentaerythritol)-piperazin phosphate] (PCPNTSi) was developed to consolidate the fire retardance of cotton fabrics. After PCPNTSi treatment, the limiting oxygen index (LOI) of cotton fabric with 30 % weight gain (CP3) was raised to 32.

An Application of Throughput Request Satisfaction Method for Maximizing Concurrent Throughput in WLAN for IoT Application System.

With the wide applications of the in systems, have become a frequently chosen communication technology due to their adaptability and affordability. In a high-density network of devices such as the , a host often meets interferences from other devices and unequal from . This results in problems between hosts communicating concurrently in WLAN.

An Interface Setup Optimization Method Using a Throughput Estimation Model for Concurrently Communicating Access Points in a Wireless Local Area Network.

The has been deployed around the globe as a major Internet access medium due to its low cost and high flexibility and capacity. Unfortunately, dense wireless networks can suffer from poor performance due to high levels of radio interference resulting from adjoining . To address this problem, we studied the , which selects the maximum or minimum power supplied to each AP so that the average among the concurrently communicating APs is maximized.

Optimization of culture medium for germination and storage conditions of pollen.

Pollen morphology, pollen vigor, and long-term pollen storage are critical for plant cross-breeding and genetic improvement of . We developed a protocol for viability determination and storage of pollen for breeding new varieties. The medium components for pollen germination was optimized by using an Orthogonal Assay Test Strategy (OATS).

First Report of Colletotrichum aenigma Causing Anthracnose of tree peony in China.

Tree peonies (Paeonia suffruticosa Andr. and hybrids) are well-known ornamental and medicinal plants cultivated in temperate and subtropical regions around the world. From June to September 2021, severe leaf spot disease was observed on 3 tree peony cultivars ('Luoyanghong', 'Moyushenghui', 'Roufurong') in Xinxiang (35º29´N, 113º95´E) and Luoyang (34º64´N, 112º49´E), Henan Province, China.

Complete chloroplast genome and evolutionary analysis of (Sapindales:Aceraceae).

In this study, the complete chloroplast genome of , a tree species native to China, was sequenced and assembled through second-generation sequencing. The complete chloroplast genome of is 155,967 bp in length with a typical quadripartite structure, encompassing 130 genes including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis of 22 related species indicated that was more closely related to and .

Etching process enhanced HO sensing performance of SnO/ZnSnO with reliable anti-humidity ability.

In this work, sol-gel and chemical etching methods are adopted to synthesize zinc hydroxystannate materials. Cubic tin dioxide and zinc stannate composite materials with a definite structure are successfully prepared at varied annealing temperatures and times by using the synthesized zinc hydroxystannate as a sacrificial template. After a gas sensing test, tin dioxide and zinc stannate composite samples etched at 650 °C and annealed for 4 h exhibit a strong response and outstanding selectivity to hydrogen peroxide.

Identification of Priority Implementation Areas and Configuration Types for Green Infrastructure Based on Ecosystem Service Demands in Metropolitan City.

During urbanization in developing countries, fragmentation of green infrastructure due to increasing populations and the expansion of construction land leads to an extremely serious imbalance between the supply and demand for urban ecosystem services. In this study, the central city of Zhengzhou, a central city in central China, was selected as the study area and the excessive demand for six ecosystem services, namely, air purification, flood regulation, heat regulation, hydrological regulation, CO sequestration and recreational services, was quantitatively evaluated. The entropy method was used to calculate the weights of various ecosystem services, and spatial overlay analysis was performed to obtain the comprehensive ecosystem service excessive demand.

DCSST Multi-Modular Equalization Scheme Based on Distributed Control.

As an important part of the DC micro-grid, DC solid-state transformers (DCSST) usually use a dual-loop control that combines the input equalization and output voltage loop. This strategy fails to ensure output equalization when the parameters of each dual active bridge (DAB) converter module are inconsistent, thus reducing the operational efficiency of the DCSST. To solve the above problems, a DCSST-balancing control strategy based on loop current suppression is presented.

Central nervous system vasculopathy caused by Fabry disease: a case report.

Background: Fabry disease is rare, and the diagnosis is often delayed. Here, we describe a case of Fabry disease resulting in vasculopathy of the central nervous system. Magnetic resonance (MR) black-blood sequence (three-dimensional T1 volumetric isotropic turbo spin echo acquisition), with the unique advantage of imaging the vascular wall, facilitated a clear identification of the vasculopathy.

Vitellogenin of Fujian oyster, Crassostrea angulata: Synthesized in the ovary and controlled by estradiol-17β.

In this study, we cloned a full-length cDNA encoding vitellogenin (Vg) in the Fujian oyster Crassostrea angulata. The complete Vg cDNA consists of 5160 nucleotides with a long open reading frame encoding 1641 amino acid residues. The deduced amino acid sequence shared high similarity with the Vgs of other mollusc, fish, nematode and arthropod species, particularly in the N-terminal region.
