Bacterioplankton plays a key role in nutrient cycling and is closely related to water eutrophication algal bloom. We used high-throughput 16S rRNA gene sequencing profile archaeal bacterial community compositions the surface of Lake Taihu. It one largest lakes China has suffered from recurring cyanobacterial A total 81 samples were collected 9 different sites months 2012. found that temporal variation microbial was significantly greater than spatial (adonis, n = 9999, P < 1e-4). The...

Organized scientific research is vital to implementing organized technological innovation in modern industrial colleges. Young teachers’ deep participation determines success. Based on the theory of planned behavior and normative activation, a survey 309 young teachers from colleges participating found that personal norms, subjective behavioral attitudes, perceived control significantly impact their intention participate. Awareness consequence, ascribed responsibility, norms indirectly...

The emergence of monoclonal antibodies has notably enhanced the outcomes for multiple myeloma. However, comprehensive assessment antibody-related pulmonary adverse events remains scarce. This pharmacovigilance study analyzed event data approved myeloma from 1 January 2016, to 31 December 2023, using OpenVigil 2.1. Adverse reports were classified based on MedDRA v24.0 into five SMQs: asthma/bronchospasm, infective pneumonia, interstitial lung disease, hypertension, and respiratory failure....

<title>Abstract</title> <bold>Background: </bold>In 2021, approximately 18.41 million women globally experienced infertility due to sexually transmitted infections (STIs), excluding human immunodeficiency virus (HIV) infections. In this study, STIs refer specifically non-HIV Although the global prevalence of is well-documented, their contribution across diverse socioeconomic contexts remains understudied. This study analysed burden caused by among reproductive age 204 countries and regions...

Asteroid body-fixed hovering problem using nonideal solar sail models in a compact form with controllable area is investigated this paper. The nonlinear dynamic equations for the are constructed spherically symmetric asteroid. feasible region solved from above by shooting method. effect of models, including ideal, optical, parametric and photon thrust, on studied through numerical simulations. influence asteroid spinning rate area-to-mass ratio discussed way. required orientations their...

Strontium is a kind of trace element. Groundwater containing strontium called mineral water when its content reaches level that beneficial for human physiology. Some groundwater resources in Shijiazhuang are rich strontium. In this study, samples collected from 103 sites were studied the hydrochemical characteristics and formation mechanism system City. The methods source provenance analysis, factor correlation runoff condition analysis carried out study. results showed eastern higher than...

The geographic location of Yongqing County is optimal, covering the center Beijing, Tianjin, and Baoding triangle. However, economic social development in recent years has resulted negative impacts on groundwater. Therefore, investigating current status groundwater chemistry great significance to provide a useful basis for future studies quality assessment. aim this study assess hydrochemical characteristics formation mechanisms unconfined aquifers using descriptive statistical multivariate...

The variability of the East Asian summer monsoon (EASM) has far-reaching effects on global climate system and environment, full understanding dynamics EASM contributes to predictions its future behavior. Here, we present a well-dated mineralogical total organic carbon record from saline inland lake in northern China which provides robust archive evolution since 16.0 cal. ka BP. Our reveals series rapid frequent millennial-scale climatic fluctuations during last deglaciation; these are...

Groundwater is an important resource for domestic use and irrigation in the Yinchuan region of northwest China. However, quality groundwater this declining due to human activities, with adverse effects on health. In order study chemical elements health, health risk drinking was calculated based actual situation China U.S. Environmental Protection Agency (USEPA) model. Moreover, sensitivity contaminant exposure water wells quantified using Monte Carlo simulation minimize uncertainty...

In palaeolimnology, microfossils play an important role as ecological indicators of lake history. A reliable interpretation microfossil data requires a comprehensive understanding transport processes well determining whether assemblages are representative their living communities. The occurrence in ostracod taphocoenoses can be identified from the population age structure valves. this study, 23 surface sediment samples Dalongchi Lake, northwestern China, were analysed for species...

Climatic instability has major impacts on water resources and catastrophic effects fragile ecosystems in arid Central Asia (ACA). Short-term (decadal to centennial) climate fluctuations over the last millennium can help predict whether future frequency of extreme events will increase. Research revealed higher moisture variability during Little Ice Age (LIA) than Medieval Warm Period (MWP). However, age control quality temporal resolution proxy records that are used make it difficult...

A novel integrated probe has been developed and applied to measure the amount of coarse water upstream downstream a newly designed stage in model steam turbine, also last 350 MW low-pressure turbine. This paper presents measurement principles results two turbines. The measurements show that velocity, flow direction, quantity size droplets over height blades cover wide range. Based on this fact, new way reduce is proposed. Initial experiments using blade with superhydrophilic surface coating...

It is known that Haloxylon has successive cambia and its radial growth rate not clear as indicated by the fact annual boundary cannot be determined dendrochronological approach. Radial increment through (RISC) layers possess similar morphological feature compared to rings megascopic cross sectional observations. Previous studies have demonstrated methods applied some species cambia. The objective of present study clarify RISC layer in ammodendron a series radiocarbon dating. Two H. specimens...

Research infrastructure (RI) refers to a large and complex science research facility or system that conducts top-level activities. In recent years, there has been tendency toward geographical concentration of RIs formation RI clusters. Some these clusters have become engines for regional social economic development. It turns out present new stage sustainable The paper tries study based on symbiosis theory in order build an analytical framework policy makers’ comprehensive understanding...
