The purpose of this review is to update cosmetic dermatologists and surgeons on the latest information about botulinum toxin injections for the treatment of the face and neck and to provide a practical guide to effective and safe technique. We review indications, recommended doses and dilutions, storage recommendations and injection techniques.
Distractor interference is subject to dilution from other nontarget elements, and the level of dilution is affected by attention. This study explores the nature of dilution when the location and color of the target is known in advance. Experiments 1 and 2 show that attention is effectively limited to the precued region, so that it is the nontarget letters appearing at the cued locations that ar...
Integer carrier phase ambiguity resolution is often a prerequisite for high precision GPS positioning. It applies to a great variety of GPS models, including those which are used in hydrographic applications and marine positioning. Since the quality of kinematic GPS positioning depends critically on whether the correct integer ambiguities are used or not, it is of importance to have easy-to-com...
We analyzed the isotope dilution residue function from a single cardiac chamber for an arbitrary inlet distribution of tracer and arbitrary mixing within the chamber, and established a general relationship between cardiac output and the chamber residue function. In our experiments, we made simultaneous temperature measurements in three left ventricular chamber subregions of the dog subjected to...
In this paper, we examine how gauge interactions can dilute the lepton asymmetry in lepton induced baryogenesis. Constraints imposed on Majorana masses keep this dilution at an acceptable level.
The micropuncture evidence relating to the location and the mechanism for concentration and dilution of the urine is reviewed. As required by the countercurrent hypothesis for urine concentration, these data demonstrate that in the presence of antidiuretic hormone, the tubular urine is first concentrated in the descending limb of the loop of Henle and then diluted in the ascending limb of the l...
in the past, mining activities have generated major acid drainage sources, which usually carry dissolved metals that flow into the main rivers of the affected basins. the study looks at natural attenuation processes in local, sub-basin and basin areas, in the el bierzo and odiel basins of spain, where coal and metal mining activities were formerly conducted. in this study, sampling and in situ ...
The properties of activated sludge systems can be characterized using image analysis procedures. When these systems operate with high biomass content, accurate sludge characterization requires samples to be diluted. Selection of the best image acquisition magnification is directly related to the amount of biomass screened. The aim of the present study was to survey the effects of dilution and m...
