Мета статті — проаналізувати історію створення Станіславом Людкевичем трьох концертів для фортепіано з оркестром, зокрема Концерту a-moll; дослідити подальшу виконавську проблематику цього твору; з’ясувати місце у творчості композитора та його жанрову унікальність. Методи дослідження ґрунтуються на історичному, джерелознавчому аналітичному методах. Історичний метод дає можливість висвітлити про...

A novel recognition method for selective determination of the hyoscine N-Butyl bromide (HBB), an antispasmodic agent for smooth muscles, was devised using extended gate field-effect transistor (EG-FET) as transducing unit. For this purpose a PVC membrane, containing hyoscine n-butyl-tetraphenyl borate ion-pair as recognition component, was coated on Ag/AgCl wire, which was connected to the exte...

We report on highly resolved core-level and valence-band photoemission spectroscopies of hydrogenated, unreconstructed 6H-SiC(0001) and (0001̄) using synchrotron radiation. In the C 1s core level spectra of 6H-SiC(0001̄) a chemically shifted surface component due to C-H bonds is observed at a binding energy (0.4760.02) eV higher than that of the bulk line. The Si 2p core-level spectra of SiC(0001...

This paper presents a systematic evaluation of a commercially available strontium-specific extraction chromatographic resin based on a crown ether (Sr spec ), for use in applications of Sr isotope ratio analysis dealing with samples displaying a complex and/or Ca-rich matrix composition. A protocol, consisting of (i) loading a sample digest in 7 M HNO3 onto the resin, (ii) rinsing the resin wit...

Acibenzolar-S-methyl (ASM) is a novel fungicide applied for crop protection. A renewable silver amalgam film electrode was used for the determination of ASM in pH 3.4 Britton Robinson buffer using square wave adsorptive stripping voltammetry (SWAdSV). The parameters of the method were optimized. The electroanalytical procedure made possible to determine ASM in the concentration range of 5 10 –3...

background and objective: the management of apoptotic cell death has been considered as a putative therapeutic strategy for cancer treatment. in the present study we investigated the putative pro-apoptotic effect of allicin, the main garlic organosulfur component with repeatedly claimed chemopreventive potency, on the human adenocarcinoma cell line ht29 as an apoptosis resistant cell line, in v...

OBJECTIVE The aim of the present study was to develop potential candidates of integrin αvβ3-targeted imaging agent, which can facilitate the diagnosis and treatment of malignant solid tumors. METHODS Peptides derived from tumstatin, named T7 and T7-6H, were derivatized to contain histidine in the C-terminus of their sequence and were labeled with (99m)Tc via nitrido and carbonyl precursors. T...

Recently, Amdeberhan and Moll gave a conjecture on ASM sequences. In this note, we show that this conjecture is not true and we give a new conjecture.

OBJECTIVE The levels of 10 heavy metals (arsenic, bismuth, cadmium, chromium, copper, iron, lead, manganese, nickel, and zinc) in gray Portland cement (GPC), white Portland cement (WPC), gray MTA (GMTA), and white MTA (WMTA) were analyzed by inductively coupled plasma-atomic emission spectrometry (ICP-AES). STUDY DESIGN One gram of each material was digested with 80 degrees C "aqua-regia" (7 ...
