The optical efficiency of concentrating solar thermal and photovoltaic systems with cylindrical geometries is asymmetrical about the optical axis. Biaxial models, based on projected incidence angles, are often used to estimate the annual performance of asymmetric concentrators. However, the use of projected angles tends to underestimate optical losses in the cover glass. In this work, a biaxial mo
Three issues are considered in this report —are assimilation and coarticulation the same process or different, are they achieved by feature spreading or by coproduction, and what level or levels of neuromotor planning or production do they represent? Tongue gestures analysed from an X-ray motion film of Bulgarian speech are presented as examples of what the tongue is made to do in speech and of ho
Right ventricular rupture, resulting in serious bleeding, is a life-threatening complication associated with negative-pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier between the heart and the sharp sternal edges has been successfully tested on pigs. In the present article, we demonstrate increased safety in NPWT through the use of the HeartShield device.
Subungual exostosis is a benign bone- and cartilage-forming tumor known to harbour a pathognomonic t(X;6)(q22;q13-14). Using global gene expression analysis and quantitative real-time PCR we could show that this translocation results in increased expression of the IRS4 gene, presumably due to disruption and/or exchange of regulatory sequences with the translocation partner, the COL12A1 gene. A cor
Studies have shown terminal QRS distortion and resultant QRS prolongation during ischemia to be a sign of low cardiac protection and thus a faster rate of myocardial cell death. A recent study introduced a single lead method to quantify the severity of ischemia by estimating QRS prolongation. This paper introduces a 12-lead method that, in contrast to the previous method, does not require access t
Aims Biogeographical evidence suggests a strong link between climate and patterns of species diversity, and climate change is known to cause range shifts. However, there is little understanding of how shifts affect community composition and we lack empirical evidence of recent impacts of climate change on the diversity of vertebrates. Using a long-term comprehensive dataset on bird abundance, we e
The article presents and analyses the editorial ideals and practices of the Enlightenment press with regard to their participatory elements. The decline of these ideals and practices, during the era of the establishment of the modern press in the 1820s, 1830s and 1840s, is discussed with regard to its advocates’ self-legitimating ambitions. These professional efforts were carried out in various wa
The overall aim of the chapter is to reflect a classroom project on creative learning processes by four “dialogues” between researcher and teacher perspectives on a sequence of themes that lead up to the morale of the tale; Computers and learning, Creativity and education, Creative teaching and Creative learning.
This study is motivated by the need to know the characteristics of the learning processes in tongue-computer interaction and to obtain a useful insight to a better design of the tongue-computer interface for computer text input. Tongue-typing can be a good alternative to hand input methods for physically disabled individuals or tasks where hand-typing is not possible. In order to evaluate the proc
A model for a special configuration in triaxial odd-odd nuclei is constructed which exhibits degenerate chiral bands with a sizable rotation, a manifestation of dynamical spontaneous symmetry breaking. A quantum number obtained from the invariance of the model Hamiltonian, which characterizes observable states, is given and selection rules for electromagnetic transition probabilities in chiral ban
The reported prevalence of malnutrition in pediatric hospitals ranges from 15% to 30% of patients, with an impact on growth, morbidity and mortality. Major deficits in nutrition care have been highlighted in European hospitals, and the implementation of nutrition support teams (NSTs) has been suggested as a means to improve malnutrition diagnosis and nutrition care for hospitalized patients. This
Bruchid beetles in the genus Zabrotes are important pests of field and stored beans all around the world and cause enormous economical losses in Mexico and Central America. Native parasitoids have been successfully used to suppress infestations by bruchid beetles in Africa, but few studies have assessed their potential to reduce seed damage in the New World and no successful biological control pro
The helicity dependence of the (γ) over right arrow(p) over right arrow -->ppi(0) reaction has been measured for the first time in the photon-energy range from 550 to 790 MeV. The experiment, performed at the Mainz microtron MAMI, used a 4pi -detector system, a circularly polarized, tagged photon beam, and a longitudinally polarized frozen-spin target. These data are predominantly sensitive to the
We use Monte Carlo methods to study the properties of the bootstrap Breusch-Godfrey test for autocorrelated errors in two versions a) by bootstrapping under the null hypothesis, restricted and b) by bootstrapping under the alternative hypothesis, unrestricted. We use the residual bootstrap for the bootstrap-BG test. Our analysis regarding the size of the test reveals that both bootstrap tests have
To estimate in gynecologically asymptomatic postmenopausal women with and without hormone replacement therapy (HRT) the prevalence at transvaginal ultrasound examination of 1) endometrial thickness ≥5.0mm, 2) intrauterine focal lesions if endometrial thickness ≥5.0mm, and 3) premalignant and malignant changes in the endometrium if endometrial thickness is ≥5.0mm and intrauterine focal lesions are
Business challenges today are becoming more numerous, and more urgent. Many companies are expanding beyond their traditional product and market boundaries, while others are forming new alliances or outsourcing supporting functions to other producers. The concept of product-service system (PSS), analysed in this study, has the potential to improve companies’ competitiveness and provide new business
