Background: E-learning is an established concept in oncological education and training. However, there seems to be a scarcity of long-term assessments of E-learning programs in oncology vis-á-vis their structural management and didactic value. This study presents descriptive, nationwide data from 2005 to 2014. E-learning oncology programs in chemotherapy, general oncology, pain management, palliat
Start with a graph with a subset of vertices called {\it the border}. A particle released from the origin performs a random walk on the graph until it comes to the immediate neighbourhood of the border, at which point it joins this subset thus increasing the border by one point. Then a new particle is released from the origin and the process repeats until the origin becomes a part of the border it
The aim was to perform a bibliometric study, and compare the quantity of publications on schizophrenia with the total medical literature in Medline during 57 years, 1950-2006. The annual additions of literature to Medline are continually increasing and form the Medline growth curve. Comparisons of the number of publications on schizophrenia, or any other disease, to this curve, may be used to esti
OBJECTIVE: We have compared the effectiveness, time required for de-airing, and safety of a newly developed de-airing technique for open left heart surgery (Lund technique) with a standardized carbon dioxide insufflation technique. METHODS: Twenty patients undergoing elective open aortic valve surgery were randomized prospectively to the Lund technique (Lund group, n = 10) or the carbon dioxide in
The objective of this study was to provide data for the design of multi-nozzle impactors giving size-fractionated samples for X-ray emission analysis and for size-distribution determinations of the α-particle activity from aerosol-particle-attached radon progenies. Different multi-nozzle impactors with laser-drilled 50–60 μm diameter nozzles designed for a cut-off diameter of about 0.05 μm were ex
1. Opioid- and FMRFamide (FMRFa)-ergic systems are believed to play antagonistic behavioral roles in both higher and lower animals. In our previous experiments on a snail, behavioral choice has been demonstrated to be dependent on a balance between FMRFa and enkephalins [7]. Here, we examined if the disturbance of the balance causes changes in the activity of both systems. Opiate receptor blocker
A good heat transfer performance with moderate pressure drop penalty, as well as a high mixing effect contributes to the increase of a solar receiver thermal efficiency. In this study, delta-winglet vortex generators (DWVGs), and the combination of DWVGs and obstacles are numerically studied to reveal the effects on a solar receiver heat exchanger and the heat transfer, friction factor and mixing.
OBJECTIVES: To report the burden of cardiovascular diseases (CVD) in the Eastern Mediterranean Region (EMR) during 1990-2015.METHODS: We used the 2015 Global Burden of Disease study for estimates of mortality and disability-adjusted life years (DALYs) of different CVD in 22 countries of EMR.RESULTS: A total of 1.4 million CVD deaths (95% UI: 1.3-1.5) occurred in 2015 in the EMR, with the highest n
Background: Current prostate cancer screening guidelines conflict with respect to the age at which to initiate screening. Objective: To evaluate the effect of prostate-specific antigen (PSA) screening versus zero screening, starting at age 50-54 yr, on prostate cancer mortality. Design, setting, and participants: This is a population-based cohort study comparing 3479 men aged 50 yr through 54 yr r
Introduction: In Sierra Leone, West Africa, there are many people with disabilities in need of rehabilitation services after a long civil war. Sierra Leone is among the ten least developed countries in the world and half of the population live under the absolute poverty line with an income less than $1.25 a day. Aim: The aim of this qualitative study was to explore the experiences of prosthetic an
We investigate the steady-state performance of a single irreversible mixing-controlled reaction between segregated reactant streams entering the annular gap between coaxial cylinders that can rotate independently. The three-dimensional Stokes flow results from the superposition of a pressure-driven Poiseuille flow along the mixer axis, and a cross-sectional Couette flow generated by the steady rot
Dodecyltrimethylammonium triflate (DTATf) micelles possess lower degree of counterion dissociation (a), lower hydration, and higher packing of monomers than other micelles of similar structure. Addition of sodium triflate ([NaTf] > 0.05 M) to DTATf solutions promotes phase separation. This phenomenon is commonly observed in oppositely charged surfactant mixtures, but it is rare for ionic surfactan
Organic material, about half of which is water soluble, constitutes nearly 80% of the wet-season aerosol mass in the Amazon Basin, while soluble inorganic salts (predominantly ammonium bisulfate) represent about 15%. A detailed analysis of number distributions and the size-dependent chemical composition of the aerosol indicates that, in principle, the sulfate fraction could account for most of the
Grammatical structure of Indo-European (IE) languages may appear to be diverse, but it is in fact more systematic than one may think. What is significant in explanation is alignment, i.e. differences represent different stages in the alignment change from active one to accusative one. This means that the grammatical structure was earlier organised by aspectual differences between perfective and im
Popular Abstract in Swedish Syftet med avhandlingen var att öka förståelsen för socialt stöd för fysisk aktivitet bland ungdomar, då det råder motstridiga uppgifter när det gäller betydelsen av socialt stöd. Tre empiriska studier ingår i avhandlingen och samtliga problematiserar kring betydelsen av det sociala stödet för fysisk aktivitet bland ungdomar under gymnasietiden. Studie I är en kvantitThe aim of the present thesis was to enhance our understanding of social support for physical activity among adolescents. Earlier findings show inconsistent results with regard to the importance of social support. The present thesis includes three empirical studies examining adolescents (16-18 years) during their years in high-school. Study I was a cross-sectional quantitative study that concluded
Objective: To characterize the trend of opioid use (number of users, dispensations and oral morphine milligram equivalents) in Catalonia (Spain). Design, setting, and participants: This population-based cohort study included all individuals aged 18 years or older, registered in the Information System for Research in Primary Care (SIDIAP), which covers >75% of the population in Catalonia, Spain, fr
For internal cooling of a turbine blade, various advanced rib turbulators can markedly contribute to the heat transfer enhancement while suffering a great increase in pressure loss. In those designs, ribs with the same configuration are periodically and evenly mounted on the channel wall. In this context, this work proposes a hierarchical design concept to optimize the rib arrangement with the des
