Two surveys of consumer satisfaction with drinking water conducted by Taiwan Water Supply Corp. are presented in this study. The study results show that although a lot of money was invested to modify traditional treatment processes, over 60% of local residents still avoided drinking tap water. Over half of the respondents felt that sample TT (from the traditional treatment process) was not a go...

Transmembrane activity was recorded from canine false tendons bathed with Tyrode's solution at 37°C. Stimulus patterns provided a 3-second pause after every ten beats. Acetylstrophanthidin was infused at concentrations up to 2 X 10~ g/ml. One or two transient depolarizations (TDs) followed the last driven response of each series. The appearance of TDs was associated with depression of normal ph...

Genome-wide proximity ligation assays allow the identification of chromatin contacts at unprecedented resolution. Several studies reveal that mammalian chromosomes are composed of topological domains (TDs) in sub-mega base resolution, which appear to be conserved across cell types and to some extent even between organisms. Identifying topological domains is now an important step toward understa...

Water shortage is severe in the North China Plain (NCP). In addition to a deficiency of water resources, deterioration of groundwater quality should be of great concern. In this study, hydrogeological analysis was conducted in combination with principal component analysis, correlation analysis and the co-kriging method to identify factors controlling the content of major ions and total dissolve...

In this paper1 I will discuss a framework for semantics which allows us to record truth-conditional and compositional analyses as dependency-style corpus annotations in a direct and fine-grained fashion. This method eliminates the need for a semantic representation formalism by decomposing semantic information into simple statements about (word or morpheme) tokens. A collection of such data wou...

We propose a temporal dependency, called trend dependency (TD), which captures a signi cant family of data evolution regularities. A simple example of such regularity might be: \Salaries of employees do not decrease." TDs compare attributes over time using operators of f<;=;>; ; ; 6=g. We de ne a satis ability problem that is the dual of the logical implication problem for TDs, and we investiga...

Classical masking aperture methods are found to be mostly inaccurate to determine the terahertz beam size in terahertz time-domain spectroscopy (TDS) experiments, owing to complex diffraction effects. Here, we present a simple and reliable method for measuring beam waists in terahertz TDS. It is based on the successive diffraction by an opaque disk followed by a small circular aperture.

The terahertz time-domain spectroscopy (THz-TDS) imaging system can obtain high-dimensional signals of the substance fingerprint information. It is necessary to process properly to use some signal processing techniques especially for high dimensional signals. As a mathematical description language, geometric algebra (GA) provides not only a powerful algebraic framework for the multi-dimensional...

Truth Diagrams, TDs, are a new diagrammatic notation for propositional logic. TDs provide: (1) representations of logical states of affairs and relations; (2) operators on such relations; (3) a test of the validity of derivations. A proof of one of de Morgan’s laws is given as an illustration of TDs. Truth Diagrams (TDs) were invented as part of a programme of research on the Representational E...

Erectile dysfunction (ED) and testosterone deficiency syndrome (TDS) are closely related. In addition to affecting men's sexual health, both conditions also affect other male health issues. Screening for ED, especially in younger men, should become standard clinical practice for the primary care physician. Possible systemic effects and associated effects of TDS are now well documented. Test...
