Ergonomics in the operating room

Surgical staff is considered to have several ergonomic risk factors, but their physical workload and musculoskeletal health have seldom been evaluated. Clinical examinations of neck and upper extremities were performed in 99 theatre nurses and 93 assisting nurses, all females. Their physical workload was assessed by questionnaire, and by technical measurements of postures, movements and muscular l

Clinical factors and outcome in T-cell lymphoma: a population-based perspective

The heterogeneous group of T-cell lymphomas consist mostly of aggressive diseasess, with generally unfavourable outcome compared to aggressive B-cell lymphomas following similar therapy. This thesis focus on outcome and risk factors for inferior survival, in an unselected population-based cohort of T-cell lymphoma patients. In the first study, outcome of the precursor malignancy T-cell Lymphoblast

GARCH-Type models and the performance of information criteria

This article discusses the ability of information criteria toward the correct selection of different especially higher-order generalized autoregressive conditional heteroscedasticity (GARCH) processes, based on their probability of correct selection as a measure of performance. Each of the considered GARCH processes is further simulated at different parameter combinations to study the possible eff

Occurrence of haemosporidian parasites in the paddyfield warbler, Acrocephalus agricola (Passeriformes, Sylviidae)

The blood parasite diversity was studied in paddyfield warblers (Acrocephalus agricola) breeding in NE Bulgaria, SW Russia and S. Kazakhstan. Nine cytochrome b gene lineages were recorded, 4 belonging to Haemoproteus spp. and 5 to Plasmodium spp. The overall prevalence of haemosporidians was 33.3%. The composition of parasites varied geographically, with six lineages recorded in Russia, five linea

Observation of a New High-spin Isomer in 94Pd

A second gamma-decaying high-spin isomeric state, with a half-life of 197(22) ns, has been identified in the N = Z + 2 nuclide Pd-94 as part of a stopped-beam Rare Isotope Spectroscopic INvestigation at GSI (RISING) experiment. Weisskopf estimates were used to establish a tentative spin/parity of 19(-), corresponding to the maximum possible spin of a negative parity state in the restricted (p(1/2)

Neutron reflectometry on highly absorbing films and its application to (B4C)-B-10-based neutron detectors

Neutron reflectometry is a powerful tool used for studies of surfaces and interfaces. The absorption in the typical studied materials is neglected and this technique is limited only to the reflectivity measurement. For strongly absorbing nuclei, the absorption can be directly measured by using the neutron-induced fluorescence technique which exploits the prompt particle emission of absorbing isoto

Performance per What?

In this short note, we argue that performance per watt, which is often cited in the graphics hardware industry, is not a particularly useful unit for power efficiency in scientific and engineering discussions. We argue that joules per task and watts are more reasonable units. We show a concrete example where nanojoules per pixel is much more intuitive, easier to compute aggregate statistics from,

Search for doubly charged Higgs bosons in like-sign dilepton final states at root s=7 TeV with the ATLAS detector

A search for doubly charged Higgs bosons decaying to pairs of electrons and/or muons is presented. The search is performed using a data sample corresponding to an integrated luminosity of 4.7 fb(-1) of pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC. Pairs of prompt, isolated, high-p(T) leptons with the same electric charge (e(+/-)e(+/-), e(+/-)mu, mu(+/-)mu(+/-)) are se

Do We Need a Distinction between Arguments and Adjuncts? Evidence from Psycholinguistic Studies of Comprehension

Within both psycholinguistic theories of parsing and formal theories of syntax, a distinction between arguments and adjuncts is central to some theories, while minimized or denied by others. Even for theories that deem the argument/ adjunct distinction important, the exact nature of the distinction has been difficult to characterize. In this article, we review the psycholinguistic evidence for an

Shock barometry of the Siljan impact structure, Sweden

The Siljan impact structure in Sweden is the largest confirmed impact structure in Western Europe. Despite this, the structure has been poorly studied in the past, and detailed studies of shock metamorphic features in the target lithologies are missing. Here, we present the results of a detailed systematic search for shock metamorphic features in quartz grains from 73 sampled localities at Siljan.

Cultural Dissimilarity and Intermarriage. A Longitudinal Study of Immigrants in Sweden 1990-2005

Intermarriage with natives is a key indicator of immigrant integration. This article studies intermarriage for 138 immigrant groups in Sweden, using longitudinal individual level data. It shows great variation in marriage patterns across immigrant populations, ranging from over 70 percent endogamy in some immigrants groups to below 5 percent in other groups. Although part of this variation is expl

Disputes and Going Concerns in an Institution for "Troublesome" Boys

Everett C. Hughes's classic concept of a "going concern" should stand for both entire institutions and for chains of activities within institutions. In this article the author explores this expanded version of Hughes's concept to show how staff and residents in a youth care setting interweave everyday concerns-meals, lessons, breaks, meetings, or other mundane but concerted projects-with interpers

The effect of the North Atlantic Oscillation on the Iraqi climate 1982-2000

In this study, we have analyzed the spatial and temporal correlation between the North Atlantic Oscillation (NAO) and the climate in Iraq, with a focus on precipitation, temperature, and number of Mediterranean cyclones. It was found that the influence of the NAO varies per climate indicator. For example, the influence is greater on precipitation than on temperature. One conclusion of the study is

Injuries in Special Transport Services – situations and risk levels involving wheelchair users

Previous research has shown that wheelchair-seated passengers using special transportation services (STS) have been injured without being involved in a vehicle crash. In order to estimate incident rate and societal costs for these vehicle-related injuries, the focus needs to be adjusted towards a traveler/incident-oriented perspective. The aim of the project was to utilize such a perspective, rela

Potential water saving from rainwater harvesting in Syria

Syria, as well as many other countries in the Middle East, faces serious water shortage problems. Available water per capita (AWPC) will dramatically decrease due to climate change, population increase, and water needed for economic growth. Rainwater harvesting can play an important role in increasing available water in Syria. However, the absence of rainwater sewer systems in many rural areas in
