The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time because it has a high power density, low emission, wide choice of fuel sources, etc. However, the performance of a stack of PEM cells degrades with respect to that of a single cell. This is mainly due to the introduction of the manifold in which supplies the reactants to individual cells. The manifold can induce an

The paper offers an analysis of some aspects (pragmatic, status, personal, feminist and stylistic) of the letters exchanged between the Danish Profesor Otto Sperling, Jr, 1634-1715) and three learned women (Anne Margrethe Qvitzow, the Cille Gad and Sophia Elisabeth Brenner), differentiating between the personal elements and the more formal and image-building ones in order to create a basis for a d

The heating effects of three PCM vests (Tmelt=32, 28 and 24 °C) were tested on a thermal manikin with constant temperature at 30 ºC in a subzero environment (Ta=-4 °C, Va=0.4 m/s). The results showed that the heating effects lasted about 3-4 hours. The highest heating effects reduced heat loss for 20-30 W/m2 on the torso during the first two hours. The results also showed that the vest with higher

We start by providing an evolutionary scenario for the emergence of semantics. It is argued that the evolution of anticipatory cognition and theory of mind in the hominids opened up for cooperation about future goals. This cooperation requires symbolic communication. The meanings of the symbols are established via a "meeting of minds." The concepts in the minds of communicating individuals are mod

CD4(+) and CD8(+) lymphocytes are mobilized in severe chronic obstructive pulmonary disease (COPD) and the CD8(+) cytokine interleukin (IL)-16 is believed to be important in regulating the recruitment and activity of CD4(+) lymphocytes. In the current study, we examined whether tobacco smoke exerts an impact not only on IL-16 in the lower airways but also in CD4(+) or CD8(+) lymphocytes or in lymp

High-resolution transmission spectroscopy has become a powerful tool for detecting atomic and ionic species in the atmospheres of ultra-hot Jupiters. In this study, we demonstrate for the first time that the Australian-built Veloce spectrograph on the 3.9-m Anglo-Australian Telescope can resolve atmospheric signatures from transiting exoplanets. We observed a single transit of the ultra-hot Jupite

Topicalization: The IO/DO Asymmetry in Icelandic* Elena Callegari and Anton Karl Ingason University of Iceland Abstract In this paper, we investigate differences in the frequency of direct-object versus indirect-object topicalization (i.e. fronting with no accompanying pronom- inal resumption) in Icelandic using the Icelandic Parsed Historical Corpus. We find that the overall incidence of DO topic

This paper investigates the outcomes of small-scale egalitarian language contact in an attempt to address whether different linguistic domains exhibit different degrees of stability and resistance to convergence among cohabitant speakers of Jahai and Jedek, two closely related Aslian (Austroasiatic) language varieties spoken in northern Peninsular Malaysia. Using nonparametric Bayesian mixture mod

Adaptive tracking of non-linear dynamic plants is currently an important area of research. The main difficulty being felt by the research community is the lack of a general modelling framework that can facilitate synthesis of a simplistic control law while being capable of providing accurate approximation of non-linear systems. In this study a novel technique based on the control-oriented U-model

Background: Neuroimaging with magnetic resonance imaging (MRI) may assist clinicians in evaluating brain injury and optimising care in comatose adults resuscitated after out-of-hospital cardiac arrest (OHCA). However, contemporary international data on its use are lacking. Aim: The primary aim was to compare the patient characteristics, early postresuscitation care, and neurological outcomes of pa

The aim of this thesis is to investigate if the Lutheran heritage, represented by a comparison between early Lutheran writings and Luther’s source of inspiration Theologia Germanica, can provide a starting point for potentially unifying dialogues within Christian circles. The background of this pursuit of unity is the ecumenical problem of the seemingly opposite views of how faith and deeds relate
