Opis:
Real-time analysis of exhaled breath is a promising new method to get quantitative information on lipophilic compounds stored in the human body. Some pilot results are presented on isoprene, which is produced as a by-product of the cholesterol synthesis and appears in exhaled breath at concentrations of about 100 parts-per-billion (ppb). The results have been obtained using proton transfer reaction mass spectrometry (PTR-MS) from healthy volunteers undergoing an ergometer challenge test (with 75 W). Peak exhalation flow of isoprene is about 400 nmol/min shortly after start of the challenge. The setup holds great potential in capturing continuous dynamics of non-polar, low-soluble VOCs over a wide measurement range with simultaneous recording of physiological parameters affecting exhalation kinetics.
Przedstawiono wstępne wyniki oznaczenia stężenia izoprenu w wydechu zdrowego człowieka. Izopren jest produktem ubocznym reakcji syntezy cholesterolu. Do oznaczenia zastosowano metodę reakcji przeniesienia protonu przy wykorzystaniu spektrometrii mas (PTR-MS).

Opis:
A method for reducing controllers for systems described by partial differential equations (PDEs) is applied to Burgers' equation with periodic boundary conditions. This approach differs from the typical approach of reducing the model and then designing the controller, and has developed over the past several years into its current form. In earlier work it was shown that functional gains for the feedback control law served well as a dataset for reduced order basis generation via the proper orthogonal decomposition (POD). However, the test problem was the two-dimensional heat equation, a problem in which the physics dominates the system in such a way that controller efficacy is difficult to generalize. Here, we additionally incorporate a nonlinear observer by including the nonlinear terms of the state equation in the differential equation for the compensator.

Opis:
Sierra Leone is one of several countries along the Rice Coast of West Africa. Gullah Geechee people live in the coastal region of the United States from Pender County, North Carolina to St. Johns County, Florida. The essential tie between Sierra Leoneans and Gullah Geechee people is rice. The purpose of the article is to present information that assess satisfaction, perceptions, preferences and characteristics of a tour of Gullah Geechee people to Sierra Leone. The study data enabled the analysis and identification of tourist satisfaction, as well as provided understanding of potential trip improvements. Implications from the study bring Sierra Leone into the fold of heritage tours as seen in Ghana and Senegal, people discovering their roots, enabling social investments in developing nations and can be of service to the Government of Sierra Leone.

Opis:
Recent advances at Institute of Grassland and Environmental Research (Aberystwyth, U.K.) in cytogenetics of the Lolium/Festuca complex places us in the advantageous position of being able to map genes of agronomic importance onto chromosome arms using fluorescence in situ hybridization (FISH). The ability to physically map genes leads to the capability for "dissecting" quantitative traits into their different components and will lead to better understanding of the complex physiological processes involved and the identification of their genetic control. By tagging genes of interest, using molecular and morphological markers, it will be possible to select and combine suites of desirable genes in a single genotype and thus produce novel cultivars by conventional breeding procedures. Programmes for introgression depend on the relationships between species and on levels of chromosome pairing. Phylogenetic relationships within the Lolium/Festuca complex are being determined using both genomic in situ hybridization (GISH) and FISH. With recent advances in genetic manipulation within the Lolium/Festuca complex, opportunities now arise for gene transfer from Lolium and Festuca species into other important agricultural crops.
