Heating detached houses in urban areas

District heating systems using cogeneration, as well as local fuel-based and electric heating systems for detached houses, are analysed. The analysis includes the whole energy system, from the natural resource to the end user, with respect to primary energy use, emission and cost. The end-use technologies studied are heat pumps, resistance heaters and boilers. It was assumed that the base-load ele

Cyclic, pseudocyclic and noncyclic photophosphorylation: new links in the chain.

Photosynthetic electron transport is coupled to ATP synthesis. This process – photosynthetic phosphorylation – proceeds by several alternative electron-transport pathways in isolated chloroplasts. The question: ‘Which of these works in real life?’ has long occupied students of photosynthesis. Recent results from structural biology and genomics suggest that the answer is ‘All of them’. The interpla

Low-intensity family therapy intervention is useful in a clinical setting to treat obese and extremely obese children

Aims. To study the influence of low-intensity solution-focused family therapy with obese and extremely obese pediatric subjects on body mass index (BMI) z-scores and self-esteem. Materials and Methods. Fifty-four obese children, aged 6-17 years, were referred to an outpatient obesity clinic. The families received solution-focused family therapy provided by a multidisciplinary team. Height and weig

3He MRI-based Assessment of Posture-dependent Regional Ventilation Gradients in Rats.

A recently developed method for quantitative assessment of regional lung ventilation was employed for the study of posture-dependent ventilation differences in rats. The measurement employed hyperpolarized 3He MRI to detect the build-up of the signal intensity after increasing numbers of 3He breaths, which allowed for computation of a regional ventilation parameter. A group of six anesthetized rat

Radiation components of beech stands in Southwest Germany

Within the framework of an interdisciplinary project on the impact of climate and forest management on beech dominated deciduous forests, forest meteorological measurements are carried out within and above different beech stands (Fagus sylvatica L.) on opposite slopes of a narrow valley located in the Swabian Jura mountain range (south-west Germany). Referring to test plots on both slopes, the fol

Space weather events in July 1982 and October 2003 and the effects of geomagnetically induced currents on Swedish technical systems

In this paper, we analyse in detail two famous space weather events; a railway problem on 13-14 July 1982 and a power blackout on 30 October 2003. Both occurred in Sweden during very intensive space weather storms and each of them a few years after the sunspot maximum. This paper provides a description of the conditions on the Sun and in the solar wind leading to the two GIC events on the ground.

Coreceptor change appears after immune deficiency is established in children infected with different HIV-1 subtypes

Change of HIV-1 coreceptor use has been connected to progression of disease in children infected with HIV-1, presumably subtype B. It has not been possible to discern whether the appearance of new viral phenotypes precedes disease development or comes as a consequence of it. We studied the evolution of coreceptor use in HIV-1 isolates from 24 vertically infected children. Their clinical, virologic

The Performativity of the Service Management Discourse - “Value Creating Customers” in Health Care

PURPOSE: The formation and spreading of market-, management- and individual-rights discourses into society, as well as the movement of consumerism, have paved the way for a transformation of the linguistic usage. The transformation suggests that the view of the care seeker has shifted from a waiting patient, via a consumer to a customer creating value. Another example of the process is that the fo

Interaction between smoking, GSTM1 deletion and colorectal cancer: results from the GSEC study

Cigarette smoking has inconsistently been associated with an increased risk of colorectal cancer. One of the enzymes responsible for the detoxification of the carcinogenic compounds present in tobacco smoke is glutathione S-transferase-mu (GST-mu). The gene that codes for this enzyme is GSTM1. In this study, we evaluated the associations and interaction between GSTM1 deletion, smoking behaviour an

Marital life course events and smoking behaviour in Sweden 1980-2000

The protective effect of marriage on smoking has been extensively established in the literature. However, less is known about the dynamics of how smoking behaviour is connected to various marital life course events, and whether there are any gender discrepancies in this respect. In this article the connection between the marital life course and smoking is analysed from a stress-related perspective

Amplitude-integrated EEG (aEEG) predicts outcome after cardiac arrest and induced hypothermia.

Objective To evaluate the use of continuous amplitude-integrated EEG (aEEG) as a prognostic tool for survival and neurological outcome in cardiac arrest patients treated with hypothermia. Design Prospective, observational study. Setting Multidisciplinary intensive care unit in a university hospital. Intervention Comatose survivors of cardiac arrest were treated with induced hypothermia for 24 h. A

Spinal sensorimotor transformation: Relation between cutaneous somatotopy and a reflex network

The projection of primary afferents onto spinal interneurons constitutes the first step in sensorimotor transformations performed by spinal reflex systems. Despite extensive studies on spinal somatotopy, uncertainties remain concerning the extent and significance of representational overlap and relation to spinal reflex circuits. To address these issues, the cutaneous projection from the hindpaw a

Common suppression pattern of eta and pi(0) mesons at high transverse momentum in Au plus Au collisions at root SNN=200 GeV

Inclusive transverse momentum spectra of eta mesons have been measured within p(T)=2-10 GeV/c at midrapidity by the PHENIX experiment in Au+Au collisions at root s(NN) = 200 GeV. In central Au+Au the eta yields are significantly suppressed compared to peripheral Au+Au, d+Au, and p+p yields scaled by the corresponding number of nucleon-nucleon collisions. The magnitude, centrality, and p(T) depende

Organic fouling of electrodialysis membranes with and without applied voltage

In this investigation organic fouling of ED membranes was studied with and without applied voltage. Fouling without the application of voltage, i.e., adsorption, was observed as an increase in the membrane resistance, and fouling with the application of voltage, i.e., conventional ED, was observed as an increase in the voltage drop across the membrane. Experiments were performed with three differe

PTSD and ADHD: underlying factors in many cases of burnout

Objective: To analyse the extent to which traumatic life events, post-traumatic stress disorder (PTSD) and the neuropsychiatric disorder attention deficit hyperactivity disorder (ADHD) can be contributors associated with burnout and the long-term sick leave that results from it. Subjects: Sixty-two individuals on long-term sick leave due to stress-related poor health and burnout, and 83 working in

Skipping the Baltic: the emergence of a dichotomy of alternative spring migration strategies in Russian barnacle geese

Since the early 1990s, an increasing proportion of barnacle geese, Branta leucopsis, bound for breeding sites in the Russian Arctic delay their departure from the wintering quarters in the Wadden Sea by 4 weeks. These late-migrating geese skip spring stopover sites in the Baltic traditionally used by the entire population. Individual geese from an arctic colony tracked by satellite or light-level

Acute pancreatitis in Soweto, South Africa: Relationship between trypsinogen load, trypsinogen activation, and fibrinolysis

Objective: It is not known why acute pancreatitis in Soweto, South Africa, pursues an aggressive course. We sought clues from circulating trypsinogen load at admission as marker of initial acinar injury, trypsinogen activation using the carboxypeptidase B activation peptide as surrogate, proteinase inhibitors, the coagulation-fibrinolysis axis, indicators of inflammation, oxidative stress markers,
