Lactose maldigestion has been under intensive research since its discovery in the 1960's. We know the prevalence of lactose maldigestion in a great number of countries and ethnic groups. However, there is often no provision made for the secondary type of maldigestion, and the study populations have sometimes been selected rather than picked at random. New methods for the measurement of lactose ...

Time Trade-Off (TTO) valuations of health are widely used in economic evaluation of health care. Current approaches to eliciting TTO values, and their use in economic evaluation, rest on specific assumptions about the way utility relates to time and health. Both the assumptions themselves and evidence of violations of them are discussed in the literature - yet the issues appear not to be widely...

Electrical resistivity measurement of freshly prepared uncured and cured soil-cement materials is done and the correlations between the factors controlling the performance of soil-cement and electrical resistivity are discussed in this paper. Conventional quality control of soil-cement quite often involves wastage of a lot of material, if it does not meet the strength criteria. In this study, i...

Medications may be important to improve or maintain your child's health. However, quite often errors are made while giving medications to babies and children. Here are questions parents should ask to avoid such errors. It is important for parents to write down the answers, so they can read them as often as they feel needed.

Sight distance obviously affects safety. Although this statement is universally accepted, the relationship between sight distance and safety has not yet been successfully quantified. One reason for this is the obvious strong correlation between sight distance and alignment. Where roads have no vertical or horizontal alignment change, the available stopping sight distance (SSD) is not limited by...

In this paper we consider the inspection of a product of which several characteristics have to satisfy given specification limits. A problem which occurs in the inspection process quite often is that a measurement error occurs in measuring the characteristics. Therefore, it is common practice to inspect each characteristic by comparing its measurement to a test limit which is slightly more stri...

We construct N-soliton solutions to the equation called Q3 in the recent Adler-Bobenko-Suris classification. An essential ingredient in the construction is the relationship of (Q3) δ=0 to the equation proposed by Nijhoff, Quispel and Capel in 1983 (the NQC equation). This latter equation has two extra parameters, and depending on their sign choices we get a 4-to-1 relationship from NQC to (Q3) ...

Since the National Institutes of Health Chronic Graft-Versus-Host Disease (cGVHD) Consensus Project in 2005, a need has emerged to evaluate cGVHD more methodically, not only to make a cGVHD diagnosis, but also to accurately classify individual organ and global organ severity, at baseline and in follow-up so that subjects participating in clinical trials may reliably be assigned an accurate resp...

This study investigated how great apes and human infants use imperative pointing to request objects. In a series of three experiments (infants, N = 44; apes, N = 12), subjects were given the opportunity to either point to a desired object from a distance or else to approach closer and request it proximally. The apes always approached close to the object, signaling their request through instrume...

A wide variety of organisms communicate via the chemical channel using small molecules. A structural feature quite often found is the lactone motif. In the present paper, the current knowledge on such lactones will be described, concentrating on the structure, chemistry, function, biosynthesis and synthesis of these compounds. Lactone semiochemicals from insects, vertebrates and bacteria, which...
