A simple and rapid gas chromatographic (GC) method was developed for the detection of cocoa butter equivalents (CBEs) in cocoa buffer (CB). It is based on the use of a 5 m nonpolar capillary column for the separation of the main triglycerides of CB according to their acyl/carbon numbers. The GC procedure was optimized to avoid thermal degradation of the triglycerides. By computing the ratio C54...

The fatty acid specificity of the bile salt-activated lipase purified from human milk was studied using C12 to C54 (total acyl carbon) saturated and the C54 unsaturated triacylglycerols. Kinetic studies indicated that the short chain triacylglycerols were hydrolyzed more readily than the long chain triacylglycerols, and that the long chain unsaturated triacylglycerols were attacked more readily...

Probably because of their interpretability and transparent nature, synthetic controls have become widely applied in empirical research economics the social sciences. This article aims to provide practical guidance researchers employing control methods. The starts with an overview introduction estimation. main sections discuss advantages framework as a design, describe settings where reliable es...

Causative agents for more than 30 percent of respiratory infections remain unidentified, suggesting that unknown respiratory pathogens might be involved. In this study, antibody capture VIDISCA-454 (virus discovery cDNA-AFLP combined with Roche 454 high-throughput sequencing) resulted in the discovery of a novel type of rhinovirus C (RV-C). The virus has an RNA genome of at least 7054 nt and ca...

Exact consumers surplus and deadweight loss are the most widely used welfare and economic efficiency measures. These measures can be computed from demand functions in straightforward ways. Nonparametric estimation can be used to estimate the welfare measures. In doing so it seems important to account correctly for unobserved heteroeneity given the high degree of unexplained demand variation oft...

Evolution of the Ti/a-GelSi trilayer reactions has been investigated using transmission electron microscopy and Auger electron spectroscopy. Instead of amorphous phase formation, as usually observed in the Ti/Si bilayer reaction, the crystalline Ti,GeS is the first phase observed during the reaction. Preceding the equilibrium C5CTi(Si,Ge),, a substitutional solid solution type C49-Ti(Si,Ge), fo...

We build a new empirical model to estimate the global impact of an increase in volatility US monetary policy shocks. Specifically, we admit time-varying variances local structural shocks from stochastic specification. By allowing for rich dynamic interaction between endogenous variables and setting, find that interest rate uncertainty not only drives output inflation volatility, but also causes...
