A flattening filter free x-ray beam mode was added to an Elekta linear accelerator by placing a flat copper plate in the filter carousel and recalibrating the electron steering servo, gun servo and dosimetry system. Machine configurations were saved onto a separate hard disk in order to remain separate from the clinical configuration. Profile measurements with a Schuster BMS diode array show that

Czechoslovak productive efficiency of the iron and steel sector fluctuated below the energy efficiency frontier. Until early 1970s, the country's iron sector was one of the least efficient ones in our sample. It was, however, during the decades of 1970s and 1980s that efficiency measures were adopted and the energy efficiency of the Czechoslovak iron and steel sector increased significantly to, de

In 2010, unmet medical care and sexual health counseling needs were assessed among students at a Ugandan University. Unmet medical care need was associated with poor mental health, experience of sexual coercion, and poor self-rated health. Unmet sexual health counseling need was significantly associated with being female, coming from an urban area, low social participation, poor mental health stat

Normal ageing in men is associated with a physiological decline in testosterone levels, but adverse environmental or psychosocial factors may also impair testosterone secretion and cause secondary biological changes. In a number of observational or experimental studies in both animals and man, it has been possible to study the influences on gonadal function of stressful life situations. To underst

Transplantation of progenitor cells to the CNS has shown promise in neuronal and glial replacement and as a means of rescuing host neurons from apoptosis. Here we examined the effect of progenitor grafts on neurite extension in the degenerating retina of rd1 ( retinal degeneration 1) mice. Transplantation of retinal progenitor cells induced increased matrix metalloproteinase-2( MMP2) secretion, pa

In this paper, we discuss the internet low bit rate codec (iLBC) with an emphesis on the frame-independent longterm prediction. The frame-independent long-term prediction is a method to exploit pitch-lag correlations in the encoding of speech without suffering multiple-frame speech degradation in connection with transmission loss. We present mean opinion scores for the iLBC codec and show by means

This study describes frequencies and associations between eating difficulties, assisted eating and nutritional status in 520 elderly patients in hospital rehabilitation. Eating difficulties were observed during a meal and nutritional status was assessed with Subjective Global Assessment form. Eighty-two percent of patients had one or more eating difficulties, 36% had assisted eating and 46% malnut

Popular Abstract in Swedish En omorganisation av det svenska Vägverket har medfört ett behov för dem att fungera som en professionell beställare enbart, utan utförande i egen regi. Det har naturligtvis också medfört en förändring i hur man hanterar upphandlingen av vägunderhåll. En väghållares främsta uppgift är att underhålla befintliga anläggningar och se till at de fungerar som avsett. Den näsA reorganization of the Swedish National Road Administration (SNRA) has urged a demand to work as a professional agency only, without any work by direct labor. This structure has enforced a change in how to handle the pavement maintenance and performance contracts are being promoted since they encourage product development and sustainability. Furthermore, SNRA desires to use the road network as a

Informal caregiving is increasingly considered a health care delivery-resource within the North European welfare states. While ‘informal’ often refers to non-professional, ‘caregiving’ connotes both affective concern (caring about) and practical action (caring for). This duality of meanings, however, often refers to the one direction in which care is given. Care, we suggest, is relational and also

BACKGROUND: Prolonged opioid use (more than 90 days) after injury puts the patient at risk for adverse effects. We investigated the patterns of opioid prescription after distal radius fracture and the effect of pre- and post-fracture factors on the risk for prolonged use.METHODS: This register-based cohort study uses routinely collected health care data, including purchases of prescription opioids
