In order to incorporate FDI factors for different MNEs, industries and countries, a unique dataset that includes country-, industryand firmlevel data is constructed. This approach avoids the aggregation or disaggregation problem by considering several levels of data simultaneously in to the analysis. The constructed database contains information on 1,223 foreign investment made by EU15 countrie...
The gas chromatography method with direct injection for quantitative determination of residual nonvolatile solvents such as 2-(2-chloroethoxy)ethanol (CEE) and N-methyl-2-pyrrolidinone (NMP) in quetiapine--the pharmaceutical active substance has been validated. Validation was performed according to the requirement of ICH validation guidelines Q2A and Q2B. Specificity, precision, accuracy, linea...
5-Alkyl-6-(substituted benzyl)-2-thiouracils 3a,c were reacted with (2-chloroethyl) diethylamine hydrochloride to afford the corresponding 2-(2-diethylamino)ethylthiopyrimidin- 4(3H)-ones 4a,b. Reaction of 3a-c with N-(2-chloroethyl)pyrrolidine hydrochloride and/or N-(2-chloroethyl)piperidine hydrochloride gave the corresponding 2-[2-(pyrrolidin-1-yl)ethyl]-thiopyrimidin-4(3H)-ones 5a-c and 2-[...
BACKGROUND Progress in maternal and neonatal mortality has been slow in many countries despite increasing access to institutional births, suggesting deficiencies in the quality of care. We carried out a systematic assessment of the quality of maternal and newborn care in three CEE/CIS countries, using an innovative approach to identify priority issues and promote action. METHODS A standard-ba...
Austrian foreign direct investment (FDI) increased quickly since 1992. The profitability of these investments did improve over the full period under consideration (1992 to 2005). In particular investments in Central and Eastern Europe became rather profitable. In 2005 total annual profits translate into an average return on equity (RoE) of 8.3%. However, returns differ to a large extent by regi...
Compounds incorporating the tetrathiafulvalene (TTF) donor unit and one or two cyanoethynylethene (CEE) acceptor units were prepared by Knoevenagel condensations of highly unstable, TTF-linked propargylic aldehyde or ketone derivatives. The resulting TTF-CEEs are very strong chromophores with low-energy end-absorptions beyond 900 nm. The molecules experience reversible oxidations of the TTF uni...
A commercially available poly(vinyl butyral) (PVB) coating was modified using a combination of 1–10wt.% bis(trimethoxysilylethyl)benzene and dibutyltin dilaurate as the hydrolysis catalyst. Results of attenuated total reflectance (ATR)–FTIR analysis indicated the modification resulted in a hybrid coating material containing silicate moieties covalently bonded to the PVB polymer chains. Gravimet...
In a recent paper, Gilman and Philips (1) pointed out that the P-chloroethyl vesicants are extremely toxic compounds which have specific effects on the bone marrow, lymphoid tissues, and the intestinal mucosa. In addition, the systemic injury produced by these mustards causes a series of complex biochemical and physiological changes in the body. This investigation was undertaken to determine th...
