This review comprehensively covers the coordination chemistry of elemental phosphorus during years 2011–2020. The main part is dedicated to activation white mediated by early and late transition metals its subsequent reactivity once in sphere a metal. burgeoning interest towards TMs has opened way new topologies types reactivity. Meanwhile, P4 metal elements also attracted significant attention...

Elements in the interstellar medium (ISM) exist form of gas or dust. The extinction and elemental abundances provide crucial constraints on composition, size, quantity Most modeling efforts have assumed total (gas dust) dust-forming elements—known as "interstellar abundances," reference "cosmic abundances"—to be solar gas-phase to environmentally independent. However, it remains unclear whether...

In this work deals about the efficient intracardial ECG analysis algorithm. The main focus was design an optimal detection method for intracardial signals based on essential intracardial measuring methods and basic principles of gathering and processing data from invasive catheters. Intracardial ECG analysis is further important step in heart behavior understanding, especially it’s electric man...

Four patients with Crohn's disease were treated with an elemental diet during pregnancy. Two had active disease and two also had symptoms of small intestinal obstruction. All went into a clinical remission within a few days of starting treatment. Treatment periods varied from two to four weeks, and were followed by elemental diet as a supplement to normal food in two patients. At term, all deli...

Integral imaging is one of the most promising techniques for delivering three-dimensional content. Most processing tasks usually require prior knowledge of the size and positions of the elemental images that comprise an integral image. In this paper we propose an automated method for calibrating the acquisition setup, by applying a preprocessing stage to an acquired integral image. The skew ang...

Boron is known as a high energy density material. This element is an important fuel for propellants and explosives. Of all the chemical elements, boron has the highest volumetric heat of combustion (140 kJ cm-3) and the third highest gravimetric heat of combustion (59 kJ g-1), after H2 and Be. Furthermore, mentioned element is used for the preparation of many alloy compounds. Therefore, study o...
