1. PEDOGENESIS ON COASTAL TABLELANDS AREA WITH LOW RANGE ALTIMETRY IN PARAÍBA STATE
RESUMO Pequenas variações de relevo influenciam na drenagem e no escoamento superficial, contribuindo para a formação de horizontes superficiais arenosos e subsuperficiais endurecidos (fragipãs e, ou, duripãs) em solos dos Tabuleiros Costeiros. Este trabalho investigou a pedogênese em área de Tabuleiros Costeiros com baixa amplitude altimétrica no E

2. 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

3. Iron Availability in Tropical Soils and Iron Uptake by Plants
ABSTRACT Given the increase in crop yields and the expansion of agriculture in low fertility soils, deficiency of micronutrients, such as iron, in plants grown in tropical soils has been observed. The aim of this study was to evaluate Fe availability and Fe uptake by corn (Zea mays L.) plants in 13 different soils, at two depths. Iron was extracted by Mehlic

4. Avaliação in vitro e in situ do potencial erosivo do suco de laranja modificado por cálcio e alguns polímeros alimentares / In vitro and in situ evaluation of the erosive potential of the orange juice modified with calcium and some food-approved polimers
O objetivo deste trabalho foi avaliar in vitro e in situ o potencial erosivo do suco de laranja modificado por cálcio e alguns polímeros alimentares. Este estudo foi dividido em quatro fases. Na primeira, as seguintes substâncias: lactato de cálcio (Ca), goma xantana (XG), hexametafosfato de sódio (HMP), tripolifosfato de sódio (STP), pirofosfato de s�

5. Formulation and evaluation of baking powders to be use in cakeâs pre-mixtures / FormulaÃÃo e avaliaÃÃo de fermentos quÃmicos para prÃ-mistura de bolo
A baking podwer is a product formed by a mixture of acid agents with sodium bicarbonate which with the influence of the heat and/or humidity, produces carbon dioxide capable of expanding the dough made with flour and starches, increasing its volume and the porosity. The objective of the present work was to optimize a formula for a baking powder to be used in

6. "Horizontes cimentados em Argissolos e Espodossolos dos tabuleiros costeiros e em Neossolos Regolíticos e Planossolos da depressão sertaneja no Nordeste do Brasil" / "Cemented Horizons in ultisol and spodosols from the coastal tablelands and in inceptisols and alfisols from the "sertaneja" depression of Northeast Brazil"
The present study was carried out in cemented horizons in Ultisols and Spodosols from the coastal tablelands, and in Inceptisols and Alfisols from the sertaneja depression of Northeast Brazil. The emphasis was concentrated on the cemented horizons developed in smooth depressions in the coastal tablelands. The main objective was to identify the cementing agen

7. Possible Role of Pyrophosphate Linkage in the Active Transport of Sodium Ions
Based upon the observation that the pyrophosphate group has a greater affinity for sodium ion than for potassium ion, and that both of these ions catalyze transphosphorylation, a simple molecular mechanism is formulated for the active transport of sodium ions across biological membranes. It is assumed that the active transport takes place along a chain of ph

8. Sodium pyrophosphate inhibition of RNA.DNA hybrid degradation by reverse transcriptase.
Sodium pyrophosphate inhibits synthesis of anticomplementary DNA during a reverse transcriptase (RNA-directed DNA nucleotidyltransferase, EC 2.7.7.7) catalyzed reaction. In the presence of pyrophosphate, the complementary DNA remains stably complexed to the RNA template. In the absence of pyrophosphate, the DNA. RNA hybrid template is degraded and anticomple

9. Influence of Phosphate Compounds on Certain Fungi and Their Preservative Effects on Fresh Cherry Fruits (Prunus cerasus, L.)
Studies were conducted to ascertain the retarding effects of four phosphate compounds (sodium hexametaphosphate, sodium tripolyphosphate, sodium tetraphosphate, and tetrasodium pyrophosphate) on molding of fresh cherries (Prunus cerasus, L.). In vitro studies on their antimycotic effects against the most common fungal spoilers, Penicillium expansum, Rhizopus

11. Nucleotide-stimulated proteolysis of histone H1.
We have identified a proteolytic system that selectively degrades histone H1 in normal human lymphocytes. Treatment of permeabilized human lymphocytes with a series of nucleotides produced a marked decrease in their histone H1 content compared to untreated cells. The nucleotide-stimulated process was selective for histone H1 because gel electrophoresis showe

12. Characterization of a Vacuolar Pyrophosphatase in Trypanosoma brucei and Its Localization to Acidocalcisomes
Inorganic pyrophosphate promoted the acidification of an intracellular compartment in permeabilized procyclic trypomastigotes of Trypanosoma brucei, as measured by acridine orange uptake. The proton gradient generated by pyrophosphate was collapsed by addition of nigericin or NH4Cl. Pyrophosphate-driven proton translocation was stimulated by potassium ions a
