Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...

The roles of trace elements have been extensively studied for decades. However, recent advances in both molecular and epidemiological studies on trace elements have provided new information and concepts on the actions of trace elements. Some of our fundamental knowledge on the roles of trace elements based on classical data should be replaced by new concept based on new findings. This series of...

One of the most highly regarded discrete event simulators used for network simulation is NS-2 (Network Simulator). NS-2 executes simulation scenarios producing various data of which trace files are considered the most beneficial for evaluating a simulation. In this paper we present the design considerations and implementation of a new tool that can be used both in TRAce FILe analysis and execut...

Abstract. This paper contains the construction, examples and properties of a trace and a trace pairing for certain morphisms in a monoidal category with switching isomorphisms. Our construction of the categorical trace is a common generalization of the trace for endomorphisms of dualizable objects in a balanced monoidal category and the trace of nuclear operators on a topological vector space w...

A theory of automatic hierarchical verification of speed-independent circuits is developed and implemented. The theory models circuits as trace structures. Trace structures represent the behaviors of circuits as sets of traces, which are sequences of transitions on the circuit's input and output wires. Trace structures form a compositional semantics for circuits: two trace structures can be com...

Parkinson’s Disease (PD) is a chronic, progressive, neurodegenerative disorder with motor and non-motor signs and symptoms. PD is caused by idiopathic degeneration of dopamine-producing cells in the substantia nigra, located in the midbrain. Recently, Trace elements have been recognized to play an important role in the development of Parkinson’s disease (PD). The aim of this review ...

Introduction: Trace elements are important for the normal function of thyroid and prevention of its diseases. Normal activities of thyroid including the synthesis of thyroid hormones and regulation of metabolism are dependent on the presence of trace elements. On the other hand, thyroid hormones may also affect the trace element levels. In this study, we investigated the effects of induced h...

Background and Objective: Serum creatinine is the most used endogenous marker of glomerular filtration rate (GFR), but it also has multiple limitations. Therefore, some surrogate GFR markers, such as beta trace protein, have been introduced for GFR estimation. The aim of our study was to estimate GFR by serum beta trace protein using three available equations and compare them to DTPA GFR as the...
