Ten young adult cats, 6 intact males and 4 intact females, with reduced renal mass were randomized to receive either normal feline maintenance diet alone or diet plus phosphorus binder in a crossover design with each treatment period of 56 days in duration (Dietary Trial A). For Dietary Trial B, following a 3-month withdrawal period, 6 cats were placed on the intestinal phosphorus binder for 9 ...

Introduction Rapid prototyping technologies are the most extensively applied methods based on additive manufacturing (AM) principles, but the first complex-shaped AM parts are already in serial production for commercial aircrafts [1]. The main advantage of rapid prototyping includes the fabrication of models and prototypes for concept assessment as well as functional testing of new products. AM...

A patient presented at the age of 77 yr with a low serum cobalamin level. Subsequent study showed that he had persistently very low R binder (TC I) cobalamin-binding capacity in serum (less than 5 ng/liter versus 213 +/- 171 ng/liter in normal controls), and that almost all of his endogenous serum cobalamin was carried by TC II instead of TC I. His saliva also demonstrated virtually undetectabl...

This paper takes as its point of departure the hypothesis that surface structures directly receive a model theoretic interpretation, without being mapped into (or derived from) a mediating level such as deep structure or LF. In particular, I am concerned with those cases centering around binding which are often thought to necessitate some kind of abstract level. Note that the standard view of b...

We propose a model for the reflectance of a particle medium made of identical, large, spherical, and absorbing particles in a clear binder. A 3D geometrical description of light scattering is developed by relying on the laws of geometrical optics. The amount of light backscattered by a single particle is determined as a function of its absorbance and refractive index. Then, we consider a set of...

Illumination flares from the past to the present have been used in order to create light and signal in critical conditions. Flare formulation consists of three components i. e., fuel (magnesium) and oxidants (sodium nitrate) and a binder. Performance of illumination flares depend on many parameters such as ratio of oxidizer to fuel, particle size of fuel, binder type and binder weight percent. ...

Despite the fact that Titanium material has been considered as difficult to cut material, its usage has been increasing day by day in all engineering sectors; wherever criticality is encountered. Many studies are going on in view of increasing tool life at high cutting speed to improve productivity. In this study, attempt has been made to see the effect of iron as a partial substitution  along ...

Hydroxyl terminated polybutadiene (HTPB) is the most commonly used binder in composite solid propellants. However, due to its non-energetic character, in practice it is just a dead weight; Therefore, replacing HTPB with an energetic polymer is essential. In this research, nitrated hydroxyl terminated polybutadiene resin (NHTPB) with 12.2% nitration rate, in combination with HTPB resin was used ...

A way to increase the specific impulse of solid propellants is using the energetic components as energetic binder or energetic plasticizer in the propellant formulations. Hydroxy terminated poly butadiene (HTPB) is the one of pre-polymer which was specifically synthesized for its use as a propellant. Incorporating of PEG into HTPB chains lead to increasing the polarity of binder and maybe preve...

objective roughness is the main parameter in interlocking bonding mechanism. yet there is no model designed to evaluate the effect of surface roughness on adhesion of coating materials in pharmaceutical sciences. materials and methods in this study polymethyl metacrylate spherical beads with different sizes were poured into 10 mm mold, then it was pressed by hand screw and finally heated to 141...
