The use of water injection in a homogeneous charge compression ignition (HCCI) engine was experimentally investigated. The purpose of this study was to examine whether it is possible to control the ignition timing and slow down the rate of combustion with the use of water injection. The effects of different water flows, air/fuel ratios and inlet pressures were studied for three different fuels, is

This article deals with the situation in Denmark during the Second World War, reviewing the various revisions which have developed to undercut an entirely heroic reading. The article connects the somewhat ambiguous relationship of Danes to Jews in the interwar period to contemporary issues. In Denmark and elsewhere in Scandinavia, prejudice against Muslims and other immigrant has begun to challeng

The in vitro replication of the Torque teno virus (IT virus) tth8 full-length genome and particle formation in a Hodgkin's lymphoma-derived cell line after transfection with cloned viral DNA were demonstrated. Analyses of the transcription patterns of tth8 and tth7 TT virus isolates in a number of lymphoma and T-cell leukemia cell lines indicated differential additional splicing events and intrage

Reference tactics – the art of guiding in the unknown How can academic librarians overcome the knowledge gap between themselves and library users? As we see it, the gap is generated by the user’s deeper knowledge of the subject topic in comparison to that of the librarian. This knowledge gives the user possibilities of handling certain premises attached to the subject and also of seeing how sub-to

This study investigates the size and power properties of three multivariate tests for autocorrelation, namely portmanteau test, Lagrange multiplier (LM) test and Rao F-test, in the stable and unstable vector autoregressive (VAR) models, with and without autoregressive conditional heteroscedasticity (ARCH) using Monte Carlo experiments. Many combinations of parameters are used in the simulations to

The carbon balance of terrestrial ecosystems is particularly sensitive to climatic changes in autumn and spring(1-4), with spring and autumn temperatures over northern latitudes having risen by about 1.1 degrees C and 0.8 degrees C, respectively, over the past two decades(5). A simultaneous greening trend has also been observed, characterized by a longer growing season and greater photosynthetic a

The treatment of simulated wastewater containing Acid Scarlet BS was tested with a two-step process that the pretreatment of Fe(II)-mediated decolorization was followed by the electrochemical oxidation with a three-phase three-dimensional electrodes. The experimental results showed that the decolorization mechanism was reductive destruction for the azo group of the dye molecular rather than floccu

Malignant fibrous histiocytoma (MFH) represents a heterogeneous soft tissue sarcoma entity. The authors compared different methods to determine immunohistochemical staining in whole tissue sections, evaluated the tissue microarray technique, and assessed immunohistochemical heterogeneity using the proliferation marker Ki-67 in 47 histopathologic tumor blocks from 11 MFHs. Whole tissue sections wer

Background and aims: Islet function is regulated by islet autonomic nerves. These nerves harbour not only the classical neurotransmitters, acetyl choline and noradrenaline, but also neuropeptides. This study examined whether the neuropeptides, pituitary adenylate cyclase activating polypeptide (PACAP) and gastrin releasing polypeptide (GRP) contribute to the regulation of insulin secretion in mode

Patients with subcutaneously placed silicone gel prostheses, for reconstruction after subcutaneous mastectomies, often complain of cold breasts as well as of slow regaining of warmth after cooling. We have used thermography in 7 such women and in 7 healthy women of the same age group as controls. Thermography has also been used in 3 women after repositioning of the subcutaneously placed prostheses

The purpose of this study was to investigate differences in anxiety and defense mechanisms between differently creative people. Two extreme groups that scored either very high or very low on a test of the creative function were selected from a larger cohort (N = 60). Each group consisted of 12 male undergraduate students, who took a test of defense mechanisms and completed anxiety inventories. The

Substantial research has been dedicated to the study of the relationship between genetic mechanisms regulating cell functions in tumors and how those tumors respond to various treatment regimens. Because these mechanisms are still not well understood, we have chosen to study the genetic makeup of 57 tumor samples from patients with follicular lymphoma (FL). Our goal was to develop a prognostic too

The spectral emission from thermographic phosphors in free flow and its dependence of laser energy per cross section area (laser fluence [J/cm(2)]) has been investigated. Temperature measurements in gaseous flows using thermographic phosphors require higher laser energy than measurements performed on surfaces, due to lower particle density. A troublesome systematic error associated with high fluen

Background: Intrauterine growth restriction (IUGR) is associated with perinatal mortality and with neurologic damage from intraventricular hemorrhage (IVH). We investigated whether S100B, a neural protein found in high concentrations after cell injury in the nervous system, is increased in serum of women whose pregnancies are complicated by IUGR and whose newborns develop IVH. We also explored the

We examined the effect of 17alpha-ethinylestradiol on immunity of the Western fence lizard, Sceloporus occidentalis. Injection of 17alpha-ethinylestradiol resulted in dose-dependent suppression of peripheral blood leukocyte levels as determined by cell counts, whereas total spleen cell levels were decreased only at higher doses of 17alpha-ethinylestradiol. In contrast, spleen cell proliferation wa

There is a need for a deeper understanding of and discussion about different cultures' influences on life-views and ethical reasoning among professionals within healthcare. A culture can be seen as a set of guidelines, both explicit and implicit, which individuals inherit as members of a particular society, and which tells them how to view the world and how to behave in it in relation to other peo
