Thallium (I) was removed from aqueous solution by using gamma-alumina nanoparticles (?ANPs) materials as nano adsorbents. Varied experimental conditions such adsorbent dose, agitation time, initial concentration, pH, and temperature effects were carried out in batch view of the optimization thallium adsorption identification mechanisms system ?ANPs-Tl. The pH effect indicated a remarkable incre...

MC4-NN2-0453 is a novel, long-acting, selective, melanocortin-4-receptor agonist developed for treatment of obesity. This first-human-dose, randomized, double-blind, placebo-controlled trial investigated the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple doses of MC4-NN2-0453 in overweight to obese but otherwise healthy subjects. The trial included a single-...

Research background. The cytotoxicity on various vital cell lines and the activity foodborne pathogens (murine norovirus 1 as a surrogate Campylobacter jejuni) of methanolic Urtica dioica L. leaf extract (UDE) were studied. Experimental approach. cytotoxic concentration 50% (CC50) was measured by linearity between UDE concentrations viability. Antibacterial effects C. jejuni analyzed broth micr...

In this paper we define a new linearity measure which can be applied to open curve segments. The new measure ranges over the interval (0,1], and produces the value 1 if and only if the measured line is a perfect straight line segment. Also, the new linearity measure is invariant with respect to translations, rotations and scaling transformations.

A Weibull analysis is presented of the dose and time relationships for the effects on 4080 inbred rats of chronic ingestion in the drinking water of 16 different doses of N-nitrosodimethylamine (NDMA) or N-nitrosodiethylamine (NDEA). The sites chiefly affected were the liver (by both agents) and the esophagus (by NDEA only). Since the experiment continued on into extreme old age, effects became...

This paper is focused on a novel design of stepped diaphragm for MEMS capacitive pressure sensor used in tire pressure monitoring system. The structure of sensor diaphragm plays a key role for determining the sensitivity of the sensor and the non-linearity of the output.First the structures of two capacitive pressure sensors with clamped square flatdiaphragms, with different thicknesses are inv...

PURPOSE The aim of this work was to create a mailable phantom with measurement accuracy suitable for Radiological Physics Center (RPC) audits of high dose-rate (HDR) brachytherapy sources at institutions participating in National Cancer Institute-funded cooperative clinical trials. Optically stimulated luminescence dosimeters (OSLDs) were chosen as the dosimeter to be used with the phantom. M...

An overview on linearity and efficiency performance optimisation in power amplifier (PA) is presented, stressing the required trade-off demanded to PA designers. For efficiency improvement, the harmonic tuning strategies are discussed, with their advantages and major drawbacks. For linearity improvement, the IMD sweet spot optimisation strategies is presented as a solution to obtain low intermo...

A criticism often levelled at functional languages is that they do not cope elegantly or eeciently with problems involving changes of state. In a recent paper 26], Wadler has proposed a new approach to these problems. His proposal involves the use of a type system based on the linear logic of Girard 7]. This allows the programmer to specify the \natural" imperative operations without at the sam...
