We investigated prospectively the risk of lung cancer in relation to socioeconomic status (SES) in 22387 middle-aged individuals who attended a screening program in the city of Malmo, Sweden between 1974 and 1992. We also examined the relationship between SES and histologic subtype in smokers. By 2003, a total of 550 lung cancer cases had been identified. Relative risks (RR) were calculated with a

The role of peripheral arterial disease in ulcerated diabetic feet has long been underestimated. Progressive claudication, rest pain and the extent of irreversible tissue loss have frequently been indications for revascularization for neuroischaemic ulcers in diabetic patients. These typical ischaemic symptoms are warning signs that are less frequent in diabetic individuals with ischaemia than tho

Objectives. We examined cancer incidence in an expanded cohort of Swedish chimney sweeps. Methods. We added male chimney sweep trade union members (1981-2006) to an earlier cohort (employed 1918-1980) and linked them to nationwide registers of cancer, causes of deaths, and total population. The total cohort (n = 6320) was followed from 1958 through 2006. We estimated standardized incidence ratios

The solar proxy Be-10, measured in natural archives, has previously been assumed to lag solar activity by 1-2 yr. This reflects its residence time in the stratosphere where its main source lies. This study, based on a 30-yr global model simulation of the atmospheric transport of Be-10, shows that the stratospheric fraction of production varies significantly with the phase of solar activity. This l

Lignocellulose is widely recognized as a Sustainable substrate for biofuels production, and the enzymatic hydrolysis is regarded as a critical step for the development of ail effective process for the conversion of cellulose into ethanol. One key factor affecting the overall conversion rate is the adsorption capacity of the cellulase enzymes to the surface of the insoluble substrate. Pretreatment

Previous studies suggest that hormone therapy may play an important role in the development of meningioma. However, it is unclear whether medication with tamoxifen can prevent meningioma. Our study cohort included all women who were diagnosed with breast cancer between 1961 and 2010, and a total of 227 535 women were identified with breast cancer with a median age at diagnosis of 63 years. Women d

Time-series of digital elevation models (DEMs) of the forefield of the Bruarjokull surge-type glacier in Iceland were used to quantify the volume of material that was mobilized by the 1963-1964 surge. The DEMs were produced by stereophotogrammetry on aerial photographs from before the surge (1961) and after (1988 and 2003). The analysis was performed on two DEMs of Difference (DoDs), i.e., a 1961-

Bacillus macerans cyclodextrin glycosyltransferase (CGTase) (EC 2.4.1.19) was covalently immobilised on Eupergit C and used in a packed-bed reactor to investigate the continuous production of long-carbohydrate-chain alkyl glycosides from alpha-cyclodextrin (alpha-CD) and n-dodecyl-(1,4)-beta-maltopyranoside (C(12)G(2)beta). The effects of buffer ion strength and pH, and enzyme loading on the immob

Osteoarthritis is a widespread disease leading to physical disability affecting quality of life. It is primarily regarded as a cartilage disease but affect all tissues of a joint. Osteoarthritis can be regarded as an organ failure. Knee osteoarthritis is common in Kuwait, especially in women. The main symptoms are pain, stiffness and weakness affecting knee function. The diagnosis is made by histo

Complementary measures for the assessment of patient thermoregulatory state, such as subjective judgement scales, might be of considerable importance in field rescue scenarios where objective measures such as body core temperature, skin temperature, and oxygen consumption are difficult to obtain. The objective of this study was to evaluate, in healthy subjects, the reliability of the Cold Discomfo

BACKGROUND: The current trend of upgrading undervalued agricultural by-products involves the recovery of natural antioxidants. The purpose of this study was to recover phenols from fresh olive mill wastewater (OMW) with their dispersion in 85 mL ethanol per 100 mL and to investigate the effect of processing parameters on the phenol content and antioxidant capacity of the extracts. Moreover, all th

This paper presents a novel method for the analysis of heart rate variability (HRV) during exercise stress testing enhanced with respiratory information. The instantaneous frequency and power of the low frequency (LF) and high frequency (HF) bands of the HRV are estimated by parametric decomposition of the instantaneous autocorrelation function (ACF) as a sum of damped sinusoids. The instantaneous

Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, w

Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a risk to water quality (especially if they are located relatively close to surface waters). In this study, six STS in Sweden (11-28 years old) were examined. Samples taken from the unsaturated subsoil beneath the distr

We present an extensive experimental and theoretical study of the proximity effect in InAs nanowires connected to superconducting electrodes. We fabricate and investigate devices with suspended gate-controlled nanowires and nonsuspended nanowires, with a broad range of lengths and normal-state resistances. We analyze the main features of the current-voltage characteristics: the Josephson current,

A new design of equilibrium hollow fibre liquid phase microextraction (HF-LPME) was developed for the determination of three freely dissolved organophosphorus pesticides (OPPs), i.e. diazinon (O,O-diethyl-O-2-isopropyl-4-methyl-6-pyrimidyl thiophosphate), chlorpyrifos (O,O-diethyl-O-[3,5,6-trichloro-2-pyridyl] phosphorothioate), and fenthion (O,O-dimethyl-O-4-methylthio-m-tolyl phosphorothioate) a

The Transition Radiation Tracker (TRT) sits at the outermost part of the ATLAS Inner Detector, encasing the Pixel Detector and the Semi-Conductor Tracker (SCT). The TRT combines charged particle track reconstruction with electron identification capability. This is achieved by layers of xenonfilled straw tubes with periodic radiator foils or fibers providing TR photon emission. The design and choic

In northern Patagonia, macrolichens form species-rich and abundant epiphytic communities in southern beech forests. Five of the most abundant lichen species in the litter were selected in order to study mass loss rate and changes in mineral composition over time. The litter bag method was applied to the foliose lichens Pseudocyphellaria faveolata, Pseudocyphellaria flavicans, Nephroma antarcticum,

An easy and rapid hollow-fibre supported liquid membrane method (HFSLM) has been developed to extract and determinate the total concentration of four dinitrophenols in environmental water at ng L-1 level. This extraction method provides a high selectivity, short extraction time and very low cost for real samples. It is a three-phase system, aqueous-organic-aqueous, where the organic solvent is hel
