Infield skins are best managed by deep and slow additions of water, but time between games limits these applications. A two-year study was conducted on a collegiate club softball infield skin to evaluate if applications soil surfactants could extend moisture levels in infields. Seven treatments (Magnus at 15.9 L ha?1 Magnus 2x 31.8 ha?1, Vivax Cascade 25.5 50.9 Tab 3.3 water m?2, Precision EZ m...

We fabricated and tested the single electron R-pump, i.e. a three-junction Al circuit with on-chip Cr resistors. Due to the presence of the resistors (R > R K ≡ h/e 2 ≈ 25.8 kΩ), the accuracy of electron transfer in the R-pump can approach the level of δI/I ∼ 10-8. Preliminary results of experiment with the R-pump made at PTB are reported.

OBJECTIVE Hypoglycemia is associated with increased mortality in hospitalized patients. We investigated the relationship between spontaneous hypoglycemia versus insulin-associated hypoglycemia and mortality in hospitalized patients. RESEARCH DESIGN AND METHODS Data for this retrospective cohort study were obtained from electronic databases of patients admitted between 1 April 2008 and 30 Nove...

The experimental study of the oxidation of cyclohexane has been performed in a jet-stirred reactor at temperatures ranging from 500 to 1100 K (low- and intermediate temperature zones including the negative temperature-coefficient area), at a residence time of 2 s and for dilute mixtures with equivalence ratios of 0.5, 1, and 2. Experiments were carried out at quasi-atmospheric pressure (1.07 ba...

[1] Atlantic basin seasonal hurricane predictions have been issued by the Tropical Meteorology Project at Colorado State University since 1984, with early December forecasts being issued every year since early December 1991. These forecasts have yet to show real-time forecast skill, despite several statistical models that have shown considerable hindcast skill. In an effort to improve both hind...

A temperature controlled 1 Ω–10 kΩ Standard resistors setup was developed at National Institute of Metrological Research, (INRIM). The aim of this realization was the involvement of the setup resistors in the traceability transfer process to high accuracy multifunction electrical instruments used in Secondary Electrical Calibration Laboratories or even their use as primary Standards in high lev...

Exceeding component maximum ratings due to transient events like current spikes can lead to premature failure of surface mount resistors due to thermal and electrical overstress. In order to accurately evaluate device parameters and their impact on the circuit behavior a coupled electro-thermal simulation method must be applied under the influence of packaging. This article presents an analysis...

Many ac quantized Hall resistance experiments have measured significant values of ac longitudinal resistances under temperature and magnetic field conditions in which the dc longitudinal resistance values were negligible. We investigate the effect of non-vanishing ac longitudinal resistances on measurements of the quantized Hall resistances by analyzing equivalent circuits of quantized Hall eff...

As-fired thick-film resistors have the resistance tolerance within ±20% and this tolerance is increased for smaller components. Therefore the novel trimming methods are necessary for microresistors, especially when they are embedded in LTCC substrate. This paper compares electrical (normalized temperature dependence of resistance, low frequency noise) and stability properties (relative resistan...
