Anionic polyurethane dispersants APUDs were used as dispersing agents in formulation of waterborne paints. The APUDs were synthesized by three steps. In the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diisocyanate IPDI, dimethylol propionic acid DMPA in presence of acetone as solvent and dibutyltin dilaurate DBTDL as catalyst. Then, carboxylic polyure...

Pigment-dispersing factor (PDF) is a neuropeptide that plays a prominent role in the circadian clock of several insects. The cockroach Leucophaea maderae was the first animal where the site of a biological clock could be located, and still is a focal point of circadian research. Although detailed studies on the action of pigment-dispersing factor and the distribution of PDF-like immunoreactivit...

Using the AutoAnalyzer, the percentage agglutination effected by the anti-D antisera studied showed a varied dependence on the ambient temperature over the manifold subsequent to the incubation period at 37 degrees C. This leads to assays which are a function of the ambient temperature. It is suggested that the entry of a relatively large volume of rouleaux-dispersing agent results in an elutio...

Stearic acid was incorporated into whey protein through emulsification to produce films. Whey protein films were prepared by dispersing 6.5% protein in distilled water. Glycerol was the plasticizer agent. Stearic acid was added at different levels (0.0 to 1.0%) and the films were analyzed at different pHs (5.0, 6.0, 7.0 and 9.0). The emulsion films were evaluated for mechanical properties, wate...

The purpose of this study is to synthesize nano-grained Calcium Hydroxyapatite (HAp) through slip casting technique. For this, hydroxyapatite powders were synthesized using two methods, wet chemical method and Ammoniacal method. The as-prepared powders and calcined powders were characterized using XRD, FTIR, to study the phases of the powders. The hydroxyapatite powder calcined at 1000°C for 2h...

Alzheimer's disease (AD) is an infectious disease caused by spirochetes, and these spirochetes form biofilms, which attract the innate immune system. The innate immune system first responder, Toll-like receptor 2, generates both NF-κB and TNF-α which try to kill the spirochetes in the biofilm, but cannot penetrate the "slime". NF-κB is also responsible for the generation of amyloid-β (Aβ) which...

A principal]multiple agent model is used to examine wildlife damage abatement and compensation programs in a setting in which farmers suffer damages and hunters use the wildlife for recreational purposes. In addition to externalities inherent in abatement, abatementrcompensation policy confronts the issue of moral hazard. By representing the principal as a wildlife management authority who acts...

In accordance with the present invention, there are provided compositions useful for the in vivo delivery of a biologic, wherein the biologic is associated with a polymeric shell formulated from a biocompatible material. The biologic can be associated with the polymeric shell itself, and/or the biologic, optionally suspended/dispersed in a biocompatible dispersing agent, can be encased by the p...
