To illustrate the spatial resolution of measurements of Mercury’s surface elemental composition by the Gamma-Ray Spectrometer on the MESSENGER spacecraft after one year of orbital observations, we have simulated a global coverage map of the 846-keV iron gamma-ray count rate. The simulated map suggests that distinct geologic units larger than 800 km in horizontal dimension will be discernable wh...

Hydride generation techniques are used routinely for the determination of As, Se, and Sb in environmental samples. Advantages include high sensitivity, simplicity and relative freedom from interferences. The current method for the hydride generation determination of As and Se, as outlined in the USEPA manual SW-846, utilizes zinc slurry methodology. A batch type method is described. Batch type ...

A 1-year study of fatal injuries was carried out in 10 provinces of the Islamic Republic of Iran based on a population of 16 740 637 in 2000-01. All reported deaths were compared and validated with other sources of death registration. Out of 66 846 deaths, 9733 (58/100 000) resulted from injuries. Overall, 14.9% of all deaths with 26.9% of years of lost life were from injuries. Most fatal injur...

I present results from an extended Migdal–Eliashberg theory of electron-phonon interactions and superconductivity. The history of the electron-phonon problem is introduced, and then study of the intermediate parameter regime is justified from the energy scales in the cuprate superconductors. The Holstein model is detailed, and limiting cases are examined to demonstrate the need for an extended ...

Influence of protein deficiency on immune response to sheep red blood cells was investigated in rats and mice with Jerne's plaque-forming cell technique. Protein deficiency resulted in a reduction in the number of antibodyproducing cells consequent upon a prolongation of cell generation time in rats. Injection of syngeneic thymocytes brings about better improvement in the im mune response of th...

Introduction: Col II and aggrecan are the main structural components of articular cartilage. The C-terminal propeptide of Col II (CP II) is said to be a marker of cartilage collagen synthesis [5], whereas the 846 epitope is used as a marker of aggrecan synthesis [6]. Previous studies have shown collagen and aggrecan degradation to be different in knee and ankle joints [7,8]. The purpose of the ...

We demonstrate that the giant chirp of coherent, nanosecond pulses generated in an 846 m long, all-normal dispersion, nanotube mode-locked fiber laser can be compensated using a chirped fiber Bragg grating compressor. Linear compression to 11 ps is reported, corresponding to an extreme compression factor of ∼100. Experimental results are supported by numerical modeling, which is also used to pr...

Cardiovascular disease is a major source of morbidity and mortality for patients with chronic kidney disease (CKD). Peripheral arterial disease (PAD) is a strong predictor of coronary artery disease and a risk factor for mortality in the general population. This is of particular interest to nephrologists because the risk for PAD is increased in CKD. Often, PAD is overlooked as a source of morbi...
