Although natural medicines are generally considered to be safer than synthetic medicines, some reports on toxicity of many herb drugs, for example Traditional Chinese Medicine (TCM), attract more and more common public attention recently. The reasons for these cardiovascular toxic effects are not always satisfactory. Not all these clinical symptoms can be observed regularly. Cardiovascular toxi...

When using optical methods turbidity is one of the main hindrances to achieving good imaging and ranging qualities in underwater applications of remote sensing, ROVs and instruments. This paper gives the principles of operation and design of an optical turbidity meter. The operation of the meter is based on illuminating the medium with light of selected wavelengths and then measuring the backsc...

While technologies for anonymous communication have been thoroughly researched and despite the existence of several protection services, the deployment of such services has not yet reached the mass market of end users. So far only a very small fraction of users are using anonymity services and early adopters, which are necessary to reach a critical mass of adopters, have not been attracted. Con...

Introduction It has been agreed that the safe endotracheal tube intracuff pressures ranges from 20cmH2O to 30cmH2O with pressures above that range being dangerous to the patient even for a short time. While there are many different methods of inflation, the cuff manometer is considered the standard. However, its applicability in clinical practice is marred with numerous hindrances. Without the ...

This paper addresses the automation of georeferencing topographic maps for the operational acquisition of spatiotemporal data on urban growth. The achieved automation of this process helps to overcome some issues and hindrances of costly manual data preparation and, thus, enables high resolution monitoring and GIS-based analyses of urban dynamics on a regional and, even, national level. Despite...

The best technical package for the future comprises trypanocidal drugs for temporary relief and the use of insecticide-treated cattle, artificial baits and aerial spraying to attack the vector, to so give more lasting security. Whether this can speed the previously slow progress will depend on overcoming past hindrances to tsetse control: sporadic support, disputes over its desirability, diffic...

Is there a universal dimension of “Meditation Depth” valid to every individual and way of meditation? Or is there only a very subjective feeling of depth, that differs from person to person and from tradition to tradition? 45 authorized meditation teachers were asked about the depth of different experiences verbalized in 30 items. The agreement is highly significant. Five clusters, interpreted ...

There is no clear-cut definition of Operational Excellence (OPEX) in theory or practice. Especially the inflationary use of the term for almost every launched improvement activity rather obscured than clarified its meaning. In some companies it has been used synonymously for cost-cutting, in others similar to Six Sigma or lean production. This chapter explains our understanding of, and our phil...

The aim of the study was to explore medical students’ experiences of e-learning and face-to-face meetings (blended learning) with a specific focus on the possibilities of and hindrances to the learning process. A pilot study was conducted with 14 medical students and a main study followed, with 119 medical students participating in three social medicine courses. Of the 119 medical students, 25 ...

The lack of informativity of samples from heterozygotic individuals is one of the hindrances in the mapping of quantitative trait loci of outbred populations, since it is not normally possible to identify the origin of each allele. One way to include these individuals in analyses would be to genotype their endosperm, considering that a heterozygote (Aa) has AAa or Aaa endosperm, when the female...
