Abstract Sequence stratigraphy and Electrosequence of the Don-Field Central Swamp depobelt Niger Delta Basin, was carried out using well logs, biostratigraphic core data. The aim this study is to re-characterise revalidate reservoirs within area provide an optimum framework for predicting reservoir character, development quality distribution. Detailed petrophysical evaluation reveals proficient...

It is known that paraconsistent logic programming, which is usually based upon a paraconsistent logic, is important in dealing with inconsistency-tolerant and non-monotonic reasoning appropriately. Firstly in this paper, a cut-free single succedent sequent system SN4 and a cut-free multiple succedent sequent system MN4 are introduced for Nelson’s paraconsistent 4-valued logic N4 [3], and the un...

Inhibition of the growth of Lactobadlus casei with folic acid as the nutrilite is a general property of 2,4-diaminopyrimidines, 2-aminopyrimidines, and condensed systems containing these groupings (1). These compounds comprise a spectrum of inhibitors. At one end lie the simpler diaminopyrimidines which are competitive antagonists of folic acid (1, 2). The center may be represented by 2-aminopu...

Earlier communications from this laboratory (l-3) have reported several studies of purine metabolism in which the individual purines were isolated by chemical procedures from nucleic acid preparations obtained either by salt extraction of desiccated tissues or by the Schmidt and Thannhauser (4) procedure for separation of the pentose (PNA) and desoxypentose nucleic acids (DNA) (5). With the rec...

determination of an optimum sample size for the evaluation of sugar beet quality is of vital importance. a desirable sugar beet sample could represent confidently the sugar content and quality of delivered beets to the sugar factories. this experiment was carried out at research station of kamalshahr, karadj, iran. the experimental field was about 2000 m2 with the distance between rows and plan...

735 sumed recurrent TB infection. He was treated with co-amoxiclav, and an intercostal drain was inserted to reduce the concomitant pleural effusion. He responded well to therapy, and an acid-fast smear of his sputum confirmed TB; TB therapy (rifampicin, isoniazid, ethambutol and pyrazinamide), as recommended by the South African Department of Health, was commenced. The patient was unable to re...

The present report summarizes a group of tracer experiments designed to test (1) whether desoxyribonucleic acid (DNA) and its associated histone are in a state of continuous nitrogen turnover in the avian red cell, (2) whether the rate of glycine incorporation into hemoglobin of the nucleated reticulocyte exceeds that observed in the mature erythrocyte, and (3) whether a difference in rate of s...

It has usually been assumed that bile pigment in the mammal is derived exclusively, or very nearly so, from the hemoglobin of mature, circulating red blood cells. Studies in the dog have revealed a close correspondence between the measurements of bile pigment excretion and the calculated degradation of hemoglobin of circulating red cells (3). A review of other studies in man, however, reveals l...

BACKGROUND The development of plasma biomarkers could facilitate early detection, risk assessment and therapeutic monitoring in Alzheimer's disease (AD). Alterations in ceramides and sphingomyelins have been postulated to play a role in amyloidogensis and inflammatory stress related neuronal apoptosis; however few studies have conducted a comprehensive analysis of the sphingolipidome in AD plas...

Compounds labeled with Cl4 and N16 have proved useful in studies of nucleic acid metabolism. Since tritium, the radioactive hydrogen isotope of atomic weight 3, is now available in relatively high specific activities, it was decided to explore the usefulness of this isotope in such studies. Inasmuch as there are no data concerning the corresponding use of deuterium, it was first considered nece...
