Abstract. The heteronuclear single quantum correlation (HSQC) experiment developed by Bodenhausen and Ruben (1980) in the early days of modern nuclear magnetic resonance (NMR) is without a doubt one most widely used experiments, with applications almost every aspect NMR including metabolomics. Acquiring this experiment, however, always implies trade-off: simplification versus resolution. Here, ...

During micro-assembly processes, surface forces influence the behavior of micro-objects more than volumic forces. Generally contacts happen between a microgripper and a micro-objet or a substrate and a micro-object. The pull-off force which represents the force required to break a contact is one of the predominant problem in micro-assembly. Now, current force measurements are mostly focused on ...

To start off, I would like to show two diagrams (Figs. 1 and 2) showing evidence of man's approach toward space. The first is the time-worn graph of altitude achievement plotted chronologically. Note the break-through produced by the advent of rocket propulsion. The dotted lines represent that portion of the achievements which have been reported at times in various news media but have never bee...

The specific scientific objectives of this project are focused on studying the dynamical coupling between meandering baroclinic jets and cut off eddies with the deep flow over steep topography. Emphasis is placed on improving our understanding of the life cycle of energetic flow perturbations excited by meandering of baroclinic jets and/or warm-core rings approaching the shelf break from the op...

The heart pumps oxygenated blood through the aorta to smaller arteries. After the blood supplies nutrients to vital organs, it returns through veins for reoxygenation in the lungs (Figures 1 and 2). Blood clots called deep vein thrombi (DVT) often develop in the deep leg veins. Pulmonary embolism (PE) occurs when clots break off from vein walls and travel through the heart to the pulmonary arte...

Horizontal violence and bullying are pervasive throughout nursing. New graduate nurses are at higher risk. Challenged with the task of making the transition from student to practitioner, new graduates often lack the confidence and social connectivity that may ward off interpersonal conflict. Continued interpersonal violence directed at new graduates may lead to negative physical and psychologic...

This paper presents an electric drive system whose motor is connected to a battery by means of a buck DC/DC converter. This motor is further connected to an ultracapacitor by means of a boost DC/DC converter. First, operation and break processes are studied when the converters are switched off as well as when they are switched on in current limitation mode. Then, a comparative analysis of the r...

By direct calculation in classical theory we derive the central extension of the off-shell symmetry algebra for the string propagating in AdS4 ×CP. It turns out to be the same as in the case of the AdS5 × S string. We also elaborate on the κ-symmetry gauge and explain, how it can be chosen in a way which does not break bosonic symmetries. ∗Email: [email protected]
