Objective: To investigate the correlation of blood flow detected by 2-Dimensional Power Doppler (2D-PD) sonography in the subendometrial-endometrial unit with the pregnancy outcome in frozen-thawed embryo transfer (FET) cycles. Study design: Prospective non-randomized observational study. Materials and methods: A total of 127 patients undergoing their first FET cycle were recruited and prepared...

the used activated carbon was derived from pine-cone and was used for the removal of acid black 1(ab1) and acid blue 113(ab113) dyes. a batch sorption study was carried out in order to obtain optimum isotherm model. the study showed the best fit of the adsorption isotherm data was obtained using the langmuir model for both dyes. the monolayer maximum saturation capacities of ab1 and ab113 dyes ...

This work is a contribution to the development of flow sensors in the oil and gas industry. It presents a methodology to measure the flow rates into multiple-zone water-injection wells from fluid temperature profiles and estimate the measurement uncertainty. First, a method to iteratively calculate the zonal flow rates using the Ramey (exponential) model was described. Next, this model was line...

B cells undergo rapid cell division and affinity maturation in anatomically distinct sites in lymphoid organs called germinal centers (GCs). Homeostasis is maintained in part by B cell apoptosis. However, the precise contribution of apoptosis to GC biology and selection is not well defined. We developed apoptosis-indicator mice and used them to visualize, purify, and characterize dying GC B cel...

Abstract. Remote-sensing records over the last 40 years have revealed large year-to-year global and regional variability in Antarctic sea ice extent. Sea area extent are useful climatic indicators of large-scale variability, but they do not allow quantification regions distinct concentration (SIC). This is particularly relevant marginal zone (MIZ), which a transitional region between open ocean...

This study uses accessibility as a performance measure to evaluate a matrix of future land use and network scenarios for planning purposes. The concept of accessibility dates to the 1950s, but this type of application to transportation planning is new. Previous research has established the coevolution of transportation and land use, demonstrated the dependence of accessibility on both, and made...

Canine hearts were isolated 6 hours, 24 hours, 3 days, 6 days, and 4 weeks after coronary artery ligation and were perfused with blood from support dogs. Electrograms were recorded from Purkinje fibers in the infarcted zone and from Purkinje fibers and ventricular muscle in noninfarcted areas. Administration of 2.5 mEq of KC1 into the coronary circulation of the infarcted hearts abolished nonin...

[1] The influence of aquifer property correlation on multiphase fluid migration and entrapment was explored through the use of correlated and uncorrelated porosity, permeability, and capillary pressure-saturation (Pc-Sat) parameter fields in a crosssectional numerical multiphase flow model. Data collected from core samples in a nonuniform sandy aquifer were used to generate three-dimensional aq...
