Is bone mineral density advantage maintained long-term in previous weight lifters?

This cross-sectional study was done in order to ascertain whether there is a lifelong beneficial effect on bone mineral density (BMD) of early, long-lasting, and intense physical exercise. Forty-eight male ex-weight lifters, mean age 64 years (range 50-79) participated. They had followed a training program of an average of 10 hours/week (range 4-20) for an average of 13 years (range 1-34). They ha

Asian Models of Agricultural Development and their Relevance to Afrika

This working paper discusses the different Asian experiences of the Green Revolution from the late 1960s to the 1980s in the perspective of earlier developments of agricultural intensification. The intention of the paper is to identify common features and conditions contributing to the considerable success of Asian agriculture over the past 30 years. The authors argue that the Green Revolution mus

Child Mortality during the Demographic Transition. A Longitudinal Analysis of a Rural Population in Southern Sweden, 1766-1894

The great decline in mortality has had a vital impact on our societies. Life expectancy has more than doubled in the past 200 years, but no acceptable explanation has yet been given for the earlier part of the decline in mortality, even though it has attracted a very broad interdisciplinary interest. When carefully examined, many of the stated explanations, such as better hygiene, more food, and i

Treatment of dye wastewater containing acid orange II using a cell with three-phase three-dimensional electrode

The removal of color and chemical oxygen demand (COD) from simulated dye wastewater containing Acid Orange II was experimentally investigated using coagulation-electrooxidation. Two kinds of coagulation methods, ferrous-mediated coagulation and electrocoagulation were tested as pretreatment. The electrooxidation was carried out in a cell with a three-phase three-dimensional electrode using granula

Lidocaine for treatment of severe seizures in newborn infants. I. Clinical effects and cerebral electrical activity monitoring

The anticonvulsive effect of lidocaine was evaluated in 46 newborn infants with severe, recurrent seizures. Before the lidocaine all infants were being given phenobarbital, and 22 infants were also treated with diazepam. Different dosages of lidocaine were tested. A loading dose of 2 mg/kg followed by i.v. infusion of 6 mg/kg/hour was the most effective dosage and had an immediate anticonvulsive e

The pursuit of heavy elements in the HgMn-type star Chi Lupi: Observations with the GHRS in the COSTAR ERA

Observations of the ultra-sharp-lined HgMn star chi Lupi made with the Goddard High Resolution Spectrograph after the Hubble Space Telescope First Servicing Mission display the effect of COSTAR corrective optics upon the spectral resolution of several observing modes. The resolution is restored to levels expected in the absence of the telescope spherical aberration for all observations made throug

Relationships Between Commuting and Social Capital Among Men and Women in Southern Sweden.

The societal need for a mobile workforce increases time spent commuting and thus also the total workday. How this affects individual well-being and social life is, however, surprisingly little known. We investigated the relation between commuting time and mode, and social participation and general trust in other people as measures of social capital, using data from public health surveys conducted

Strengths and weaknesses of the aniline-blue method used to test mushroom (1→3)-β-D-glucans obtained by microwave-assisted extractions

The parameters to extract polysaccharide-enriched fractions (PEF) from mushrooms using MAE (microwave-assisted extraction) were adjusted following a full factorial 3 2 experimental design. The highest yield and total carbohydrate values, using Lentinula edodes as model mushroom, were obtained at 180 °C and 30 min. Several mushroom species were submitted to MAE and their PEF yields ranged between

Perioperative alcohol cessation intervention for postoperative complications

Background: Risky consumption of alcohol is a global problem. More than 3.3 million deaths annually are associated with risky use of alcohol, and global alcohol consumption continues to increase. People who have high alcohol consumption often require planned and emergency surgical procedures. Risky drinking is associated with increased postoperative complications such as infections, cardiopulmonar

Charge and Spin Transport in Parallel-Coupled Quantum Dots in Nanowires

This thesis explores crystal-phase engineering of nanowires to fabricate advanced quantum structures for charge and spin transport studies. Quantum dots formed by crystal-phase tuning during epitaxial growth of InAs nanowires were used as a starting point to realize and electrically characterize two different types of parallel-coupled quantum dots; electron-hole quantum dots and electron-electron

Wick action in mature mortars with binary cements containing slag or silica fume – The relation between chloride and moisture transport properties under non-saturated conditions

Moisture and ionic transport under non-saturated condition is an important, but poorly understood transport phenomena particularly for mature systems containing supplementary cementitious materials. This paper investigates the moisture and chloride profiles of 3-year old mortars containing Portland cement (OPC), slag and silica fume (SF) after long-term (30–48 months) wick action exposure in 1.09

Sewage sedimentation ponds - a lost bird paradise : a nostalgic return visit and case study

Sewage ponds with exposed sludge are known to be excellent feeding sites for waders during migration. They still exist in parts of the world but are disappearing in pace with introduction of modern methods which do not involve open exposure of the sludge. Here I report a five-year study from a Swedish plant with open sludge ponds in the 1950s when many similar ones were still active. I counted the

Chemically-resolved particle mass composition in a Swedish residence assessed by a Time-of-Flight Aerosol Mass Spectrometer

A number of deleterious health effects have been identified from exposure to outdoor airborne particulate matter. Given that in developed countries we spend majority of our time indoors, in private homes about 65 % (Brashe et al., 2005), the understanding of this exposure is important, yet knowledge is sparse. Particle levels indoors are affected by indoor sources, infiltration from outdoors or pa

Conceptual Design and Operation of an Integrated Mycoprotein Fermentation Process Focusing on Side Stream Resource Recovery

Mycoprotein är ett köttalternativ som de flesta svenskar ätit någon gång i sitt liv. Men trots att det är betydligt mer miljövänligt än vanligt kött har det fortfarande stora brister speciellt när det kommer till vattenutsläpp. I en värld där rent vatten är en bristvara finns det mycket att vinna på att kunna återvinna vattnet men kanske går det också att skapa nya värdefulla produkter samtidigt.Mycoprotein from the fungi Fusarium Venenatum A3/5 has been used as a meat alternative for a long time but little attention has been paid to the waste it creates. When the fungi is fermenting it uses a lot of water which is sent to the drain after the process is finished. This water contains large quantities of both nutrients and biomass. As circular economy is becoming more important for environm
