Purpose: 843 Duplex scanning is a useful noninvasive screening tool for the detection of carotid bifurcation disease.Internal carotid artery (ICA) peak systolic velocity (PSV) and ICA/common carotid artery (CCA) PSV ratios are proven metrics determining 70%-99% ICA stenosis.A potential disadvantage of using dramatically increasing systolic velocity
Medicines informal market in Congo, Burundi and Angola: copyright and sub-standard antimalarials
Abstract Background The presence of counterfeits and sub-standards in African medicines market is a dramatic problem that causes many deaths each year.The increase of the phenomenon of pharmaceutical counterfeiting is due to the rise of the illegal market and to the impossibility to purchase branded high cost medicines.Methods In this paper the res
A Piston-Rotaxane with Two Potential Stripes: Force Transitions and Yield Stresses
We examine a rod piston-rotaxane system, where the positions of several mobile rings on the axle are controlled by an external force acting on one of the rings.This allows us to access the translational entropy of the rings.For a simple rotaxane molecule with an axle that BOOK has uniform ring-axle interactions along its length, the molecule behave
Inverse radiative transfer problem for soil properties retrieval from bidirectional reflectance measurements
The difficulty of obtaining some experimental soil properties leads to the use of many approaches 843 such as the inverse technique to estimate those properties.However, when confronted with complex problems, the inverse approach requires an accurate numerical method for solving both direct and indirect problems as well as the good choice of invers
Contamination characteristics, source analysis and health risk assessment of heavy metals in the soil in Shi River Basin in China based on high density sampling
To explore the contamination of heavy metals in the Shi River Basin BOOK soil in China, a high density sampling of surface soil was conducted.In this study, an absolute principal component scores multiple linear regression model (APCS-MLR) was used to identify the sources of heavy metals in the soil and quantify their amounts.The methods to assess
