A covalent organic framework immobilized Cu catalyst was prepared and applied for synthesis of <italic>N</italic>-arylated products by Chan–Lam coupling reaction arylboronic acids with various amines.

Salinity is one of the major abiotic stresses limiting crop growth and yield. This study investigated underlying mechanisms Trichoderma asperellum Q1 in promoting cucumber under salt stress, including abilities strain to solubilize phosphate produce phytohormone. The results showed that T. could inorganic or organic activities phosphatases phytase be detected culture supernatant. In hydroponic experiments, seedlings was increased system treated by filtrate with tricalcium calcium phytate...

Iron (Fe) deficiency is a major plant nutritional disorder in many parts of the world, particularly areas with saline soils. Among numerous root‐associated microbes that are beneficial for nutrient uptake, Trichoderma spp. most effective rhizosphere fungi enhancing growth and resistance to biotic abiotic stresses. To investigate potential mechanisms action on insoluble Fe soil, which difficult plants absorb utilize, high siderophore‐producing strain T6, was isolated from cucumber plants. The...

Objective Acute pancreatitis (AP) is an acute inflammatory disease that can lead to multiple system dysfunction, including kidney injury (AKI). AKI occurs in 10%-42% of AP patients, and studies have shown early (48 hours) associated (AP-AKI) increases the risk death pancreatitis. Anion gap (AG) a common index clinical evaluation acid-base imbalance important critically ill patients. The aim this study was investigate relationship between baseline anion values patients with intensive care...

The morphing wing with large deformation can benefit its flight performance a lot in different conditions. In this study, variable camber compliant leading and trailing edges is designed by large-displacement mechanisms. mechanisms are carried out hyperelastic structure topology optimization, based on nonlinear meshless method. A laminated leading-edge skin to fit the curvature changing phenomenon of edge during deformation. demonstrator was manufactured testify capability. Comparing other...

Salt stress is a major environmental factor that inhibits crop growth. Trichoderma spp. are the most efficient biocontrol fungi and some of strains can stimulate plant Phosphate solubilization known as one main mechanisms in promoting growth, but underlying phosphate salinity still need to be explored. The asperellum Q1 isolated identified our lab beneficial rhizosphere fungus with high activity. It could produce acid alkaline phosphatases when using insoluble organic phosphorus sole source,...

This study compared the management of chronic childhood conditions in Chinese families and identified predictors style.A survey was conducted 2008-2009 on a convenience sample 387 caregivers children with conditions.Six family styles (FMSs) were identified: accomplished, uncertain managing, joint managing difficulty, struggling, competent managing. The FMSs related to functioning child. Changes parents' employment, geographic location, diagnosis predicted placement cluster.Understanding will...

A topology optimization, based on a coupling method of finite element and meshless method, is proposed for continuum structure. reasonable arrangement the domain can guarantee accuracy methods meanwhile keep computational efficiency method. Besides, as adopted, displacement boundary conditions are applied to elements nodes by standard dual-level density approximant carried out approximate interpolate unified continuous field. An unstable phenomenon observed in interface domain, leading...

We introduce the topological conditional entropy for countable discrete amenable group actions and establish a variational principle it.

Taking the marriage custom of “not settling in husband’s home (BuLuo FuJia)” Zhuang people western Gui as research object, our team went to Lipotun Tiandong County, Baise City, where live, investigate, collect and organise data, hoping enrich actual details home” by taking entry point, understand reasons for its recent changes loss tradition. We hope use an point change times.

The natural vibrational frequencies of biological particles such as viruses and bacteria encode critical information about their mechanical states they interact with local environment undergo structural evolution. However, detecting tracking these vibrations within a context at the single particle level has remained elusive. In this study, we track motions single, unlabeled virus under ambient conditions using ultrafast spectroscopy. ultrasonic spectrum an 80-100 nm lentiviral pseudovirus...

ABSTRACT Aim To explore and compare the self‐perceived competence level of new graduate nurses with expected that nurse managers believe should have in general. Design Two cross‐sectional empirical studies. Methods independent studies were carried out 12 tertiary hospitals September 2020 November 2021, respectively. Participants 1017 less than 2 years work experience 306 who completed an online survey. Results The score nursing was 74.77 ± 14.35, expectation 74.21 15.04. values 18 items...

Jujube is an important economic crop in the Xinjiang Uygur Autonomous Region. Microbial diversity rhizosphere essential for plant quality; however, soil bacterial and community structure jujube have not been characterized this region. In study, we used pyrosequencing to analyze at different growth stages Hetian, Kashi, Aksu prefectures. These results revealed a greater 8-year as compared with 3-year-old taken from same sampling area. Moreover, samples obtained Kashi prefecture showed largest...
