Being there in the flex : humanities and social science collaborations with nonacademic actors
In the face of reduced public funding of science and increased demands for ‘value for money’, academic researchers find themselves hard pressed to produce relevant research and demonstrate their utility to society. These pressures are particularly prominent in the humanities and social sciences (HSS) where practical value is frequently questioned. This article investigates how HSS can be made ‘rel
Broad online learning EdTech and USA universities : symbiotic relationships in a post-MOOC world
From 2012 USA universities entered new partnerships with private sector companies including Silicon Valley start-up Coursera. Coursera spearheads a new broad online learning segment of the fast growing global ‘educational technology’ (EdTech) sector. They offered free ‘massive open online courses’ (MOOCs) for global, universal learner audiences. Since 2015 several USA universities and Coursera exp
Biogas and ethanol from wheat grain or straw : Is there a trade-off between climate impact, avoidance of iLUC and production cost?
Current EU policy calls for decreased emissions of greenhouse gases (GHG) by i.e., replacing fossil fuel in the transportation sector with sustainable biofuels. To avoid indirect land use change (iLUC), the EU at the same time strives to limit the use of crops and to increase the use of residues. In this study we compare climate impact and production cost for biogas and ethanol based on wheat grai
Anabolic and antiresorptive actions of locally delivered bisphosphonates for bone repair
During the last decades, several research groups have used bisphosphonates for local application to counteract secondary bone resorption after bone grafting, to improve implant fixation or to control bone resorption caused by bone morphogenetic proteins (BMps). We focused on zoledronate (a bisphosphonate) due to its greater antiresorptive potential over other bisphosphonates. Recently, it has beco
Energy and exergy analysis of a cruise ship
In recent years, the International Maritime Organization agreed on aiming to reduce shipping's greenhouse gas emissions by 50% with respect to 2009 levels. Meanwhile, cruise ship tourism is growing at a fast pace, making the challenge of achieving this goal even harder. The complexity of the energy system of these ships makes them of particular interest from an energy systems perspective. To illus
The duration of exercise as a regulator of bone mass
Exercise is associated with increased peak bone mineral density (BMD). To determine the relationship between the duration of exercise and BMD, we measured BMD of the axial and appendicular skeleton by dual-energy X-ray absorptiometry (DXA), and speed of sound (SOS), broadband attenuation (BUA), and stiffness index by quantitative ultrasound (QUS) of the calcaneus, in 67 active male national soccer
Bone loss in relation to menopause : A prospective study during 16 years
This prospective study evaluated bone loss in the peri- and postmenopausal period in 156 women followed from age 48 to 64 years. All women were premenopausal at the start of the study. Areal bone mineral density (g/cm2) was measured by single-photon absorptiometry (SPA) of the forearm at the 1 cm level (BMD 1 cm) and the 6 cm level (BMD 6 cm) every second year. Onset of menopause (MP) was determin
The evidence that exercise during growth or adulthood reduces the risk of fragility fractures is weak
There has never been, and will never be, a randomized double-blind placebo-controlled trial demonstrating that exercise in youth, adulthood or old age reduces fragility or osteoporosis-related fractures in old age. The next level of evidence, a randomized, controlled but unblinded study with fractures as an end-point is feasible but has never been done. The basis for the belief that exercise reduc
Skeletal effects of exercise in men
No prospective randomized study with fracture as end point exists in men. Data from retrospective and prospective observational and case control studies suggest that activity in men is associated with reduced fracture risk. This may be correct, but consistently replicated sampling bias may produce the same observation, as these studies are hypothesis generating, never hypothesis testing. Higher mu

Heterogeneity in the growth of the axial and appendicular skeleton in boys : Implications for the pathogenesis of bone fragility in men
Men with spine fractures have reduced vertebral body (VB) volume and volumetric bone mineral density (vBMD). Men with hip fractures have reduced femoral neck (FN) volume and vBMD, site-specific deficits that may have their origins in growth. To describe the tempo of growth in regional bone size, bone mineral content (BMC), and vBMD, we measured bone length, periosteal and endocortical diameters, B
On exposure to anorexia nervosa, the temporal variation in axial and appendicular skeletal development predisposes to site-specific deficits in bone size and density : A cross-sectional study
Skeletal development is heterogeneous. Throughout growth, bone size is more maturationally advanced than the mineral being accrued within its periosteal envelope; before puberty, appendicular growth is more rapid than axial growth; during puberty, appendicular growth slows and axial growth accelerates. We studied women with differing age of onset of anorexia nervosa to determine whether this tempo
Bone size and volumetric density in women with anorexia nervosa receiving estrogen replacement therapy and in women recovered from anorexia nervosa
Anorexia nervosa is associated with bone loss during adulthood, but may also delay skeletal growth and mineral accrual during growth. We asked the following questions. 1) Is anorexia nervosa associated with reduced bone size and reduced volumetric bone mineral density (vBMD)? 2) Is estrogen replacement therapy (ERT) or recovery from anorexia nervosa associated with normal bone size and vBMD? Using
Bone mass and density of the head
Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry in the upper half of the skull, in 324 residents (178 women and 146 men, age-range 20-87 years) in the city of Malmo, Sweden. Since muscular activity influences the skeleton we found it was of interest to compare one region influenced by physical load with one virtually unaffected by physical stress. The skull may be assum
Can high physical activity give increased bone mass in various parts of the skeleton?

Very long-term survival and late sudden cardiac death in cardiac resynchronization therapy patients
AIMS: The very long-term outcome of patients who survive the first few years after receiving cardiac resynchronization therapy (CRT) has not been well described thus far. We aimed to provide long-term outcomes, especially with regard to the occurrence of sudden cardiac death (SCD), in CRT patients without (CRT-P) and with defibrillator (CRT-D).METHODS AND RESULTS: A total of 1775 patients, with is
Does comprehensive geriatric assessment (CGA) in an outpatient care setting affect the causes of death and the quality of palliative care? A subanalysis of the age-FIT study
Purpose: The purposes of this study were to retrospectively study whether comprehensive geriatric assessment (CGA) given to community-dwelling old patients with high health care usage has effects regarding: (1) the cause of death and (2) the quality of the provided palliative care when compared to patients without CGA-based care. Method: This study includes secondary data from a randomised control
Influence of extensive green roofs to the local microclimate: cooling assessment for a social housing project in the south of Brazil
This study analyses the influence of green roofs in different heights of the urban canopy layer: from the pedestrian level, up to 1m above the rooftop, in a social housing project in the South of Brazil. In order to quantify the cooling contribution of green roofs to the local microclimate, the housing project was simulated with ENVI-met 4.0 in the summer season. The variables used to assess the g
