Although plants are exposed to a great number of pathogens, they usually defend themselves by triggering mechanisms able to limit disease development. Alongside signalling events common to most such incompatible interactions, modifications of plasma membrane (PM) physical properties could be new players in the cell transduction cascade. Different pairs of elicitors (cryptogein, oligogalacturoni...
BACKGROUND Over the last decade, a few studies have investigated the possible adverse effects of ambient air pollution on preterm birth. However, the correlation between them still remains unclear, due to insufficient evidences. METHODS The correlation between air pollution and preterm birth in Guangzhou city was examined by using the Generalized Additive Model (GAM) extended Poisson regressi...
in industries, preventive maintenance (pm) is not a new practice to minimise the sudden breakdown of production machine. pm will be performed at predetermine intervals to provide a balance between failure cost and component utilisation (aging). however, most of pm interval is based on experience or original equipment manufacturer (oem) recommendations. consequently, the benefits from pm are not...
OBJECTIVE We explored the relationship between atmospheric concentrations of fine particulate matter and children cough variant asthma. PATIENTS AND METHODS 48 children all diagnosed with cough variant asthma were placed in the cough asthma group while 50 children suffering from typical asthma were place in typical asthma group. We also had 50 cases of chronic pneumonia (the pneumonia group) ...
We can obtain a second conventional formula (${\rm CF_{II}}$) with two components by extending the ${\rm CF_{I}}$ one component for Bose-Einstein Correlation (BEC). used CF_{II}}$ to analyze BEC at $Z^0$-pole as part of OPAL collaboration. $R_1({\rm G})=0.91\pm 0.03$ fm ($\lambda_1=0.61\pm 0.03$) and $R_2({\rm G})=2.57\pm 0.44$ ($\lambda_1=0.35\pm 0.09$) are estimated interaction region, where ...
Background and objective Particulate matter (PM) has a fatal effect on health. There have been many studies the use of plants such as trees shrubs eco-friendly sustainable biofilter for removal PM. In forming more green space, ground cover play an important role in multi-layered planting. This study was conducted to investigate ability reduce PM, targeting Korean native with high availability u...
Aim: This work investigates the correlation between the cardiac electrical activity underlying spontaneous ventricular tachyarrhythmias and their modes of onset. Signals: We analyzed 81 episodes of spontaneous ventricular tachycardia (VT) and ventricular fibrillation (VF) lasting at least 5 seconds from 17 patients. The cardiologist classified VT/VF malignancy by considering fast VT as more mal...
Remote sensing and GIS techniques were developed and evaluated to retrospectively analyze the impacts of the McNally Fire on air quality. The McNally Fire was a large wildfire over 54,700 ha (150,000 acres) in size that occurred in the Sequoia National Forest, California, 21 July through 26 August 2002. MODIS satellite images and NOAA pictures were used to digitize smoke plumes. Smoke plumes we...
