Abstract To analyze the short-term effects of air pollution on hospitalization rates individuals with acute exacerbation chronic obstructive pulmonary disease (AECOPD), stroke, and myocardial infarction (MI) after adjusting for confounding factors including weather, day week, holidays, long-term trends in Jinan, China. Hospitalization information was extracted based data from primary class 3-A hospitals Jinan 2013 to 2015. The concentrations PM 2.5 , 10 SO 2 NO O 3 were obtained Environment...
Abstract Multiple human immunodeficiency virus (HIV)-1 genotypes in China were first discovered Yunnan Province before disseminating throughout the country. As HIV-1 epidemic continues to expand Yunnan, genetic characteristics and transmitted drug resistance (TDR) should be further investigated among recently infected population. Among 2828 HIV-positive samples newly reported quarter of 2014, 347 identified as recent infections with BED-captured enzyme immunoassay (CEIA). Of them, 291...
Soil moisture is a key factor in the water and heat exchange energy transformation of ecological systems critical importance to accurate obtainment soil content for supervising resources protecting regional global eco environments. In this study, we selected monitoring networks Naqu, Maqu, Tianjun on Qinghai–Tibetan Plateau as research areas, established database surface microwave scattering with AIEM (advanced integral equation model) mathematical expressions backscattering coefficient,...
In complex environments, three-dimensional path planning for agricultural UAVs involves the comprehensive consideration of multiple factors, including obstacle avoidance, optimization, and computational efficiency, which significantly complicates achievement safe efficient flight. As environmental complexity increases, search space expands exponentially, thereby making problem more challenging to solve categorizing it as an NP-hard problem. To obtain optimal or near-optimal within this vast...
Aim To investigate the effect of temperature, humidity and concentration ambient air pollution on hospitalization AECOPD. Method Hospitalization record was obtained from Shenyang Medical Insurance Bureau, concluding patient's age, gender, income hospital time, outcome hospital; Generalized additive model used to analyze relationship between humidity, Result The ozone admission rate in male group higher than that female group. Ambient had a weak influence age≤50 It found optimal lag day for...
Analytical formulations are presented to determine the bending moment-curvature relationship of a helical layer in unbonded flexible pipes. Explicit expressions describing variation both stiffness and moment as function applied curvature given. The approach takes into account nonlinearity response caused by interlayer slip. contribution local torsion individual elements behavior layers is included. Theoretical results for typical pipe using nonlinear formulation compared with experimental...
Understanding how seasonal and annual variations in dew formation are controlled by environmental elements of a crop field is necessary for utilizing as water resource agricultural production. Radiative cooling intensity, wind speed, vapor pressure the key formation. However, detailed investigation these affect variation unexplored. We examined relationship between characteristics (frequency, amount, duration) semiarid during cultivation period corn (April–September) three years. In spring...
Soil salinization is one of the major forms land degradation processes from all over world. The dielectric constant plays an important role in process soil salinity retrieval by using microwave remote sensing. Dobson model has been widely used to simulate nonsaline soil, but estimated result did not perform well for saline soil. Moreover, ions' concentration related salinity, and electrical conductance a critical factor that influences imaginary part constant. Therefore, relationship between...
An analytical model is given to investigate the tensile armour behaviour of unbonded flexible pipes close end fittings under axial tension with no friction. The deviation from initial lay angle taken describe path single wire and determined by minimisation strain energy functional using Euler equation. obtained simultaneous differential equations are transformed into a boundary value problem which solved numerically. solution found neglecting twist cross-section respect centre-line....
