Activation of molecular nitrogen by transition metal complexes is an area of current interest as investigations using the inert N2 molecule to produce higher-value organonitrogen compounds intensify. In an attempt to extend the addition of hydride reagents E-H (where E = BR2, AlR2, and SiR3) to the dinitrogen complex ([NPN]Ta)2(mu-H)2(mu-eta1:eta2-N2) [1; where NPN = (PhNSiMe2CH2)2PPh], the rea...

OBJECTIVE The 7th edition of AJCC staging manual implicitly states that only T1 and T2 lesions that lack regional lymph node metastasis but have tumor deposit(s) will be classified in addition as N1c, though it is not consistent in that pN1c is also an option for pT3/T4a tumors in the staging table. Nevertheless, in this TNM classification, how to classify tumor deposits (TDs) in colorectal can...

The initiation, execution, and completion of complex locomotor behaviors are depending on precisely integrated neural circuitries consisting of motor pathways that activate muscles in the extremities and sensory afferents that deliver feedback to motoneurons. These projections form in tight temporal and spatial vicinities during development, yet the molecular mechanisms and cues coordinating th...

The explosive proliferation of battery powered equipment in the past decade has created unique requirements for a voltage regulator that cannot be met by the industry standards like the LM340 or the LM317. These regulators use an NPN Darlington pass transistor (Figure 1), and will be referred to in this document as NPN regulators. The demand for higher performance is being met by the newer low-...

The class of compounds called non-protein nitrogen (NPN) is not a homogeneous group of similar chemicals but rather an operational term for the remainder of nitrogen in milk and formula once the protein fraction has been removed. NPN therefore consists of widely diverse types of compounds, ranging from urea to complex nitrogen-containing oligosaccharides. It is obvious that the capacity of an i...

The objective of this study was to identify Acinetobacter in a traditional cheese from west Azarbaijan, Iran, and to study the lipolytic and proteolytic activities of these bacteria in ripening of white brine cheese. Acinetobacter is a gram negative bacteria which can be found in different sources as dairy products. Lypolysis and proteolysis characteristic of this bacteria and...

Two experiments were conducted to determine the influence of supplemental nonprotein N (NPN) provided daily (D) or every other day (2D) on ruminant performance and N efficiency. Treatments included an unsupplemented control (CON) and a urea (28.7% CP) or biuret (28.6% CP) supplement provided D or 2D at 0700. In Exp. 1, five wethers (39 +/- 1 kg BW) were used in an incomplete 5 x 4 Latin square ...

This work compares NPN and PNP SiGe HBTs fabricated simultaneously using Ge' implantation in the base to achieve an average Ge concentration of 4at.%. Electrical measurements are presented and discussed with TEM and SIMS analysis. The results show that the PNP HBTs give superior performance to the NPNs, as they have more ideal collector characteristics. The NPN HBTs exhibit collector-emitter le...

Skeletal abnormalities consisting of shortened long bones, enlarged joints and splayed front feet in newborn calves were associated with cows fed apple pomace supplemented with nonprotein nitrogen (NPN) during late gestation. Measurements of x-ray films of the metacarpus and lumber vertebrae from 86 calves in three trials showed that calves from dams fed apple pomace and NPN had longer, thicker...
