This paper presented thorium and neptunium quantification of a new synthesized powder, (Th,Np)O2 mixed oxide. Thorium was quantified by Thermal Ionization Mass Spectrometry using Isotope Dilution (ID-TIMS) which is one the most accurate methodology to determine actinide mass fraction. The (sample-spike) mixture isotope ratio measured TIMS reference method for major determination, i.e. total eva...

Brain regions typically contain intermixed subpopulations of neurons with different connectivity and neurotransmitters. This complicates identification of neuronal phenotypes in electrophysiological experiments without using direct detection of unique molecular markers. A prime example of this difficulty is the identification of dopamine (DA) neurons in the midbrain ventral tegmental area (VTA)...

An approximate method is presented to investigate Mgy the interlaminar stresses near the free edges of composite N laminate plates that are subjected to a combined NI~ thermo-mechanical loading. The method is based upon N~ admissible function representations of stresses which account Q!~) for the effects of both the global mismatches and the local ,~!k/ mismatches in two of the elastic properti...

Thyroid hormone (TH) is essential for adult brain function and its actions include several key roles in the hypothalamus. Although TH controls gene expression via specific TH receptors of the nuclear receptor class, surprisingly few genes have been demonstrated to be directly regulated by TH in the hypothalamus, or the adult brain as a whole. This study explored the rapid induction by TH of ret...

The present study was carried out to evaluate three interpolation methods including weighted moving average (WMA) with the power of 2 and 3, Kriging and Cokriging methods. Data of 23 wells in Mazandaran province were collected in fall and spring 2006. Seven parameters including electrical conductivity (EC), pH, total dissolved solids (TDS), sodium adsorption ratio (SAR), total hardness (TH), ch...

PURPOSE The purpose of this study was to establish a sensitive and semiquantitative method for the detection of minimal residual disease of neuroblastoma, the most common solid tumor in childhood. EXPERIMENTAL DESIGN Analysis was performed on a molecular level by reverse transcription-PCR using a new, real-time detection method. We measured two genes simultaneously, tyrosine hydroxylase (TH) ...

We present and compare various approaches to a classical selection problem on Graphics Processing Units (GPUs). The selection problem consists in selecting the k-th smallest element from an array of size n, called k-th order statistic. We focus on calculating the median of a sample, the n/2-th order statistic. We introduce a new method based on minimization of a convex function, and show its nu...

(2009), Constraints on the utility of MnO 2 cartridge method for the extraction of radionuclides: A case study using 234 Th, Geochem. [1] Large volume (10 2 –10 3 L) seawater samples are routinely processed to investigate the partitioning of particle reactive radionuclides and Ra between solution and size-fractionated suspended particulate matter. One of the most frequently used methods to prec...
