Sector field ICP-MS has been used to determine 239+240 Pu activity and 240 Pu/ 239 Pu atom ratio profiles in a sediment core obtained in 1997 from the Danube Delta region of the Black Sea. The 239+240 Pu activity profile reveals the presence of a 1963 stratospheric fallout peak, along with two more recent peaks stemming from fluvial transport of Chernobyl Pu through the Danube watershed into th...

Multilingual generation is becoming an increasingly important aspect of implemented systems that showcase the abilities of generation systems. Most such systems require multiple grammars, one for each language which must be deployed. Yet little is known about the development costs for additional languages which are developed not from scratch, but by adapting existing resources. We ported a stan...

It has been demonstrated that it is possible to produce methanol in one step reasonable amounts by electrolysis of CO 2 and H O gasses dissolved under 28 bar at 240 °C contact with an electrolyte consisting solid CsH PO 4 additions polyvinyl butyral (PVB) acting as a binder. The cathode was designed sandwich layer copper catalyst porous platinum electrode. anode consisted ruthenium metal covere...

aim : this study evaluated the results and efficacy of serum ca 19-9 in determining the nature of a pancreatic solid mass in patients referred for investigation of possible malignancy. background : a wide variety of tumor markers have been proposed for pancreatic cancer but currently the only one with any practical usefulness for diagnosis, prognosis, and monitoring of treatment is “ca 19-9 ”. ...

INTRODUCTION Preanalytical specifications for urinalysis must be strictly adhered to avoid false interpretations. Aim of the present study is to examine whether the preanalytical factor 'time point of analysis' significantly influences stability of urine samples for urine particle and dipstick analysis. MATERIALS AND METHODS In 321 pathological spontaneous urine samples, urine dipstick (Urisy...

The inverse sandwich Ca-C8H8-Ca is predicted to be an open-shell singlet state. Since the C8H8 ligand prevents the spin-up and spin-down electrons of different calcium atoms from forming Ca-Ca bonds, the spin-coupling electrons lead to a singlet diradical character. The metal-ligand interaction contributes to the stability of Ca-C8H8-Ca against dissociation and isomerization. For the coordinati...

The objectives of this study were to characterize and quantify postharvest losses apples under commercial conditions in Santa Catarina state, Brazil. Two experiments conducted using ‘Gala’ ‘Fuji’ apples. first experiment was the most important causes loss fruit treated or not with 1-methylcyclopropene (1-MCP) then held controlled atmosphere (CA) storage. This storage facilities from 2007 2010. ...

Aortocaval fistula (ACF)-induced volume overload (VO) heart failure (HF) results in progressive left ventricular (LV) dysfunction. Hemodynamic load reversal during pre-HF (4 wk post-ACF; REV) results in rapid structural but delayed functional recovery. This study investigated myocyte and myofilament function in ACF and REV and tested the hypothesis that a myofilament Ca(2+) sensitizer would imp...

Rats fed diets with cadmium (Cd) concentrations similar to that found in human diets, and nutritionally marginal with respect to iron (Fe), zinc (Zn), and calcium (Ca) retained 10 times more Cd in the duodenum than rats fed adequate mineral diets. In the current study, 2 experiments were performed to determine the role of intestinal metallothionein (MT) in the accumulation of duodenal Cd, and t...
