An improved mixed order model is presented to describe the thermolumunescence (TL) glow peaks. In this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken ...

The present study is an attempt to investigate some features of Radial Basis Functions (RBFs) approximation methods related to variational problems. Thereby authors applied some properties of RBFs to develop a direct method ...

A projective parameter of a geodesic as solution of certain ODE is defined to be a parameter which is invariant under projective change of metric. Using projective parameter and Poincaré metric, an intrinsic projectively ...

Simple harmonizable processes (SHP) introduced by Soltani and Parvardeh (2006) are a large class of nonstationary processes which includes stationary and periodically correlated (PC) processes. Detection and estimation of ...

Let 𝑀 be a lattice module over the multiplicative lattice 𝐿. 𝑀 is said to be a comultiplication 𝐿-module if for every element 𝑁 of 𝑀 there exists an element 𝑎∈𝐿such that 𝑁(0𝑀:𝑀𝑎. Our objective is to investigate ...

Two newly-created water-soluble complexes of palladium(II)/platinum(II)-dithiocarbamate, [Pd/Pt(phen)(pyr-dtc)]NO3 (phen = 1,10-phenanthroline and pyr-dtc = pyrrolidinedithiocarbamate) were synthesized. Also, their chemical ...

Despite two decades of artificial spawning of wild carp (Cyprinus carpio) to rehabilitate natural populations in the southeastern Caspian Sea, there are still no appropriate physiological criteria for selecting competent ...

An efficient and chemoselective procedure for the preparation of 1, 1-diacatates (acylals) from various aldehydes with acetic anhydride in the presence of Brønsted acidic ionic liquid [Msei]Cl as a reusable catalytic system ...

The ground state properties of liquid 𝐻𝑒3 in the presence of magnetic field have been investigated. In our calculations, we have employed a variational many-body formalism using the Lennard-Jones and Aziz inter-atomic ...

The Kasian volcanic body is located in the eastern margin of the Zagros thrust belt, close to the Sanandaj-Sirjan metamorphic zone. These volcanic rocks are mainly composed of andesite and andesite-basalt rocks with ...

Freeze-thaw is one of the most powerful weathering agents that may cause a rapid change in the initial engineering properties of stones, and limit their durability. Freeze-thaw induces stress over the pores' surface of ...

An efficient synthesis of 1, 8-dioxo-octahydroxanthens and 1, 8-dioxo-decahydroacridines from the reaction of 5,5-dimethyl-1,3-cyclohexanedione (dimedone) with aromatic aldehydes bearing electron-donating or withdrawing ...

This study was conducted to determine taxonomic feature of fishes from the headwaters of three riverine systems in Kohgiluyeh and Boyer-Ahmad province (K & B) in southwestern Iran during 2011 to 2013. Fifteen species ...

The Normalized Difference Vegetation Index (NDVI) derived from the SPOT 4 satellite has been widely used to monitor moisture-related vegetation condition. The relationship between vegetation and climate index, however, is ...
