1. Determining the effects of encapsulated polyphosphates on quality parameters and oxidative stability of cooked ground beef during storage
Abstract Effects of encapsulated (e) sodium tripolyphosphate (STP), sodium pyrophosphate (SPP) and various combinations of encapsulated and un-encapsulated (u) forms of these polyphosphates on lipid oxidation in the cooked ground beef during storage (0, 1, 7 d at 4 0C) were determined. pH, color, cooking loss (CL), thiobarbituric acid reactive substances (T

2. Structure-flammability relationship study of phosphoester dimers by MLR and PLS
Abstract Polyphosphonates and polyphosphates having good flame retardancy represent an important class of organophosphorus based polymer additives. In this analysis the flammability of 28 previously synthesized polyphosphoesters, modelled as dimmers, was explored using the multiple linear regression (MLR) and Partial Least Square (PLS) methodology. The stati

3. DiagÃnese acelerada de caulim à zeÃlita NaA para uso no abrandamento de Ãguas. / DiagÃnese sped up of kaolinm to the zeolite NaA (LTA)for use in the water softener.
Zeolite NaA (LTA) has been successfully synthesized by hydrothermal route, in which kaolim was used as silicon and aluminum source. The obtained zeolite was characterized by X-ray diffraction, X-ray absorption, thermogravimetry (TG), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), infrared absorption spectroscopy (IR), luminescen

4. Preparação e caracterização do Sistema polifosfato misto contendo o ion Erbio
According to available published data, antimony polyphosphates have not attracted much attention from researchers. Currently polyphosphates of trivalent elements, including those of lanthanides, are widely employed in glasses suitable for light transmission within the region of telecommunication windows. In this case, the combination of antimony and rare ear

5. Coadjuvants of buccal hygiene in dog feeding / Coadjuvantes de higiene bucal na alimentaÃÃo de cÃes
Although, veterinary dentistry is a relatively new specialization, the dental disease is one of the most common problems affecting pets. Among the affections attacking the buccal cavity the most prevalent is the periodontal disease, whose determinant factor is the bacterial plate. From the 1990, products which have received in their formulation minerals inhi

6. Polifosfatos em detergentes em pó comerciais
A didactic experiment is proposed in order to identify inorganic phosphates in home laundry detergents by ascending paper chromatography. Chemical principles related with hard water are also investigated. The role of polyphosphates in detergent formulations is discussed and the softening of hard water by sodium tripolyphosphate is illustrated. Several chemic

7. Nanoparticulas de polifosfato de aluminio
M polyphosphates colloidal systems are versatile sources of new materials. In recent years we have demonstrated the formation of sols, gels, foams and hollow particles, by using these salts. They are formed by precipitation in aqueous media; this phase separation yields different products, depending on the actual conditions used. Particles of noncrystalline

8. Dinucleoside polyphosphates: strong endogenous agonists of the purinergic system
The purinergic system is composed of mononucleosides, mononucleoside polyphosphates and dinucleoside polyphosphates as agonists, as well as the respective purinergic receptors. Interest in the role of the purinergic system in cardiovascular physiology and pathophysiology is on the rise. This review focuses on the overall impact of dinucleoside polyphosphates

9. Polyphosphate Inhibition of Growth of Pseudomonads From Poultry Meat
Both commercial polyphosphates and equivalent mixtures of chemically pure polyphosphates inhibited the growth of nonfluorescent pseudomonads in a synthetic medium. Fluorescent strains grew after a short lag. Inhibition was not caused by high pH, but rather by chelation of metal ions essential to the growth of the bacteria. Mg++ and the natural competitive ch

10. Diphosphoinositol Polyphosphates: Metabolic Messengers?
The diphosphoinositol polyphosphates (“inositol pyrophosphates”) are a specialized subgroup of the inositol phosphate signaling family. This review proposes that many of the current data concerning the metabolic turnover and biological effects of the diphosphoinositol polyphosphates are linked by a common theme: these polyphosphates act as metabolic

11. Phosphorus-31 and Nitrogen- 14 NMR Studies of the Uptake of Phosphorus and Nitrogen Compounds in the Marine Macroalgae Ulva lactuca1
Cytoplasmic phosphomonoesters and inorganic phosphate, as well as vacuolar inorganic phosphate and polyphosphates, gave rise to the major peaks in 31P nuclear magnetic resonance (NMR) spectra of the marine macroalgae Enteromorpha sp., Ceramium sp., and Ulva lactuca which were collected from the sea. In contrast, NMR-visible polyphosphates were lacking in Pyl

12. Degradation of aspartate transcarbamylase in Bacillus subtilis is deficient in rel mutants but is not mediated by guanosine polyphosphates.
Degradation of aspartate transcarbamylase in growing and starved Bacillus subtilis was deficient in relA and relC mutants, but these effects were not correlated with differences in the intracellular level of guanosine polyphosphates.
