Den pågående expansionen av järnvägstransporter, för både personresor och varutransporter, gör att den rälsbundna trafiken ökar kraftigt. I samband med att personresor och pendling med tåg och järnväg ökar sker också en expansion av antalet mer eller mindre slutna stationsmiljöer under mark. Dessa miljöer kan innebära en hälsorisk genom kombinationen av slutna utrymmen och höga halter av luftburna

The existence of a counterexample to the infinite-dimensional Carleson embedding theorem has been established by Nazarov, Pisier, Treil, and Volberg. We provide an explicit construction of such an example. We also obtain a non-constructive example of particularly simple form; the density function of the measure (with respect to a certain weighted area measure) is the tensor-square of a Hilbert spa

Sidewall proximity, characterized by the gap distance (G) between border pin-fin column and sidewall in a pin-finned microchannel with in-line arrangement, plays a significant role on pressure drop and heat transfer characteristics. To better understand the thermal performance and explore the underlying mechanisms, a comprehensive comparison is numerically developed among three representative micr

In this study, we present the development of a mobile system to measure real-world total respiratory tract deposition of inhaled ambient black carbon (BC). Such information can be used to supplement the existing knowledge on air pollution-related health effects, especially in the regions where the use of standard methods and intricate instrumentation is limited. The study is divided in two parts.

The study intention is to understand the nature of digital publishing for childrenin Sweden and showed, among other things, that digital publishing to a large extentis reproductions of print books. The paper argues that results of the case studycan be explained by long-time structures in publishing of print books for childrenbut also that there are barrier breakers.In order to map digital book pub

The future of nations and nationalism appears to many to be more uncertain than ever in view of the growing interdependence of the planet. The question of whether globalization heralds the end of nationalism cannot be answered properly without distinguishing between nation and state. In the case of the state, the question is whether states can preserve their sovereignty intact in an age when polit

Temafloxacin increased interleukin-2 production and mRNA levels and enhanced thymidine incorporation in stimulated lymphocyte cultures. Gamma interferon mRNA levels were unaffected. Temafloxacin also stimulated interleukin-2 gene induction, as revealed in a chloramphenicol acetyltransferase reporter gene system. However, temafloxacin exerted significantly weaker effects in these respects than did

The fluoroquinolone antibiotic, ciprofloxacin (cipro), induces hyperproduction of interleukin 2 (IL-2) and interferon-γ (IFN-γ) in stimulated human peripheral blood lymphocytes. In this investigation an enhanced and prolonged IL-2 and IL-2 mRNA response was also detected in both stimulated (T cell mitogens or alloantigens) murine splenocytes and in the stimulated murine T cell line EL-4 in the pre

The highly variable complementary determining region 3 (CDR3) of antibodies is generated through recombination of immunoglobulin heavy chain variable (IGHV), diversity, and joining genes. The codons encoding the first residues of CDR3 may be derived directly from the IGHV germline gene but they may also be generated as part of the rearrangement process. Data of the nucleotide composition of these

This review discusses the role arbuscular mycorrhizal fungi play in the regulation of plant nutrient transporter genes. Many plant nutrient transporter genes appear to be transcriptionally regulated by a feed-back mechanism that reduces their expression when the plant reaches an optimal level of nutrition. Their down-regulation in mycorrhizal roots, therefore, would be predicted as a result of sym
