The equivalent pipe network (EPN) model is an effective way to fluid flow in large-scale fractured rock masses with a complex fracture due its straightforwardness and computational efficiency. This study presents the EPN for characterizing through three-dimensional networks using Monte-Carlo method. extracted from original discrete (DFN) used simulate processes. validity of proposed modeling ap...

In 1952, Kornberg and Pricer (1) reported in a preliminary communication that P-choline1 labeled with P32 and Cl* was converted by liver enzymes to a lipide which was not further characterized. The ratio of P32 to Cl4 in the product was closely similar to that of the labeled P-choline, suggesting incorporation of both phosphorus and choline as an intact unit into a phospholipide, presumably lec...

The “P32” Astronomical Observation Template (AOT) provided a means to map large areas of sky (up to 45×45 arcmin) in the far-infrared (FIR) at high redundancy and with sampling close to the Nyquist limit using the ISOPHOT C100 (3×3) and C200 (2×2) detector arrays on board the Infrared Space Observatory (ISO). However, the transient response behaviour of the Ga:Ge detectors, if uncorrected, can ...

The lipid-containing bacteriophage PRD1 infects a variety of gram-negative cells by injecting its linear double-stranded DNA genome into the host cell cytoplasm, while the protein capsid is left outside. The virus membrane and several structural proteins are involved in phage DNA entry. In this work we identified a new infectivity protein of PRD1. Disruption of gene XXXII resulted in a mutant p...

1. A method for isolating nuclei in quantity from mammalian tissues is described. 2. The rate of uptake of radioactive phosphorus by nuclei is found to be quite rapid. The phosphorus was shown not to be taken up by exchange. 3. Nuclei of tumors accumulate more radioactive phosphorus than normal liver nuclei. This was shown to be due to mitotic activity and not a form of metabolism peculiar to t...

The FLP protein that is encoded by the 2-microns plasmid of yeast Saccharomyces cerevisiae is a 45-kDa site-specific recombinase that belongs to the Int family of recombination proteins. FLP catalyzes a recombination event within the plasmid by binding specifically to each of three 13-base pair (bp) symmetry elements of the FLP recognition target (FRT). We have shown previously that partial pro...

BACKGROUND & OBJECTIVES The available serological techniques for the diagnosis of leptospirosis have less sensitivity during the early stage of the disease. Understanding of leptospiral proteins expressed during acute and convalescent phases of leptospirosis, would be help the develop of new serodiagnostic strategies. Therefore, the present study was carried out to identify (i) an antigen that ...

OBJECTIVE Cystic craniopharyngiomas are considered the most common intracranial nonglial tumor in children with the tendency for cyst formations. The aim of this study was to evaluate the effect of intracystic phosphorus 32 (P32) therapies on controlling the growth of the cystic component of craniopharyngioma. MATERIALS & METHODS This clinical study was conducted on 47 patients with cystic cr...

NACTIVATION of bacteria and bacteriophages by decay of incorporated radio‘active phosphorus (P”) has been reported by STENT and FUERST (1955), FUERST and STENT (1956), STRAUSS, VAHARU, FRICKEY and MATHESON (1956), TESSMAN, TESSMAN and STENT (1957), MCFALL, PARDEE and STENT (1958), and KAUDEWITZ, VIELMETTER and FRIEDRICH-FREKSA ( 1958). These authors have suggested that the P32 disintegrations w...
