Barriers to energy crops in Poland from the farmers perspective

With the recent expansions of the European Union, there are now 12 new member states that are implementing European policy. One of these policies, with implications for energy production and security, is the Common Agricultural Policy. This article will focus on the impact the Common Agricultural Policy can have on farmers in Poland who have been encouraged by calls to cultivate energy crops. In a

Would prostate cancer detected by screening with prostate-specific antigen develop into clinical cancer if left undiagnosed? A comparison of two population-based studies in Sweden

OBJECTIVE: To assess the risk of over-diagnosing and over-treating prostate cancer if population-based screening with serum prostate-specific antigen (PSA) is instituted. PATIENTS AND METHODS: From a serum bank stored in 1980, PSA was analysed in 658 men with no previously known prostate cancer from a well-defined cohort from Goteborg, Sweden (men born in 1913); the incidence of clinical prostate

Modeling through drying of tissue-effect of pore size distribution on drying characteristics

A general model for through drying of tissue was developed based on the equations of continuity in combination with correlations for heat and mass transfer. The model incorporates different geometric descriptions together with corresponding heat and mass transfer correlations for flow through cylindrical conduits and flow through packed beds of cylindrical fibers. At low intensities, i.e., at low

Application of the PIV technique to measurements around and inside a forming drop in a liquid–liquid system

A particle image velocimetry (PIV) method has been developed to measure the velocity field inside and around a forming drop with a final diameter of 1 mm. The system, including a microscope, was used to image silicon oil drops forming in a continuous phase of water and glycerol. Fluorescent particles with a diameter of 1 μm were used as seeding particles. The oil was forced through a 200 μm diamet

Area social characteristics and carotid atherosclerosis.

Objectives: To explore the effect of social characteristics of residential areas on carotid atherosclerosis prevalence. Methods and results: The associations among area social characteristics and B-mode ultrasound determined carotid plaque-score (a semi-quantitative scale measuring the degree of atherosclerosis in the carotid bifurcation area) were cross-sectionally investigated in a general popul

Chronic nicotine treatment eliminates asymmetry in striatal glucose utilization following unilateral transection of the mesostriatal dopamine pathway in rats

Partial hemitransection was performed through a knife lesion at the meso-diencephalic level in rats to sever the mesostriatal dopamine system. During the subsequent 2 weeks the animals received 0.125 mg/kg/h of nicotine continuously via an osmotic minipump implanted s.c. To achieve prompt high nicotine levels, 4 i.p. injections of 0.5 mg/kg nicotine were, in addition, given during the first 2 h fo

Saccharomyces kluyveri as a model organism to study pyrimidine degradation.

Abstract The yeast Saccharomyces kluyveri (Lachancea kluyveri), a far relative of Saccharomyces cerevisiae, is not a widely studied organism in the laboratory. However, significant contributions to the understanding of nucleic acid precursors degradation in eukaryotes have been made using this model organism. Here we review eukaryotic pyrimidine degradation with emphasis on the contributions made

End-of-life decision-making in six European countries: descriptive study

Background Empirical data about end-of-life decision-making practices are scarce. We aimed to investigate frequency and characteristics of end-of-life decision-making practices in six European countries: Belgium, Denmark, Italy, the Netherlands, Sweden, and Switzerland. Methods In all participating countries, deaths reported to death registries were stratified for cause (apart from in Switzerland)

ABCB6 (MTABC3) excluded as the causative gene for the growth retardation syndrome with aminoaciduria, cholestasis, iron overload, and lactacidosis

GRACILE syndrome (growth retardation, aminoaciduria, cholestasis, iron overload, lactacidosis, and early death; OMIM 603358) is a rare metabolic disorder with autosomal recessive mode of inheritance. So far it has been diagnosed only in patients with Finnish ancestors. The GRACILE locus has been positioned to a restricted region of chromosome 2q33-37, but the causative gene remains to be identifie

The medium is the message: The media history of the press

This paper argues for the relevance of the media history of the press. Using a broad and open media concept, this perspective should be understood as the study of the construction and communication of the self-images and ideology of the press. Rather than describing the complex of problems as images that are ‘spread’ through one channel (newspapers) by one actor (the press), it should be seen as a

Catalysis as a resonance effect, V. Factors that determine the isokinetic temperature in catalytic reactions

When describing isokinetic effects by the model of selective energy transfer by resonance, it is sometimes found that the frequency of the forcing oscillator is quite different to that of the reacting molecule, i.e."resonance" is not a very good concept to use. By noting that the two frequencies thus found are related to each other as the ratios of small integers, e.g. 4:3, this dilemma is resolve

Time resolved X-ray diffraction and non-thermal inelastic X-ray scattering

Atomic processes like e.g. molecular vibrations, chemical reactions or phase transitions happen on picosecond down to femtosecond time scales. Novel pulsed X-ray sources or alternatively ultrafast X-ray detectors allow the investigation of these processes in real time. A powerful tool for the investigation of the dynamics in crystalline materials is time resolved X-ray diffraction (TRXD). As an ex

Individual Facial Coloration in Male Eulemur fulvus rufus: A Condition-dependent Ornament?

Researchers studying individual variation in conspicuous skin coloration in primates have suggested that color indicates male quality. Although primate fur color can also be flamboyant, the potential condition dependence and thus signaling function of fur remains poorly studied. We studied sources of variation in sexually dichromatic facial hair coloration in red-fronted lemurs (Eulemur fulvus ruf

Student nurses' lived experience of preceptorship. Part 1--in relation to learning

In this first part of a research project a phenomenological approach was applied to understanding student nurses' experience of preceptorship. The lived experience of seventeen student nurses learning within a preceptor-preceptee relationship on hospital wards formed the basis of the study. Tape-recorded interviews were conducted, transcribed and analysed. The phenomenological hermeneutic analysis

Film Extrusion and Film Weldability of Poly(lactic acid) Plasticized with Triacetine and Tributyl Citrate.

Film extrusion and welding of biodegradable polymer films are important processes that must be considered in the development of compostable packaging materials. Film extrusion of poly(lactic acid) (PLA) has proved to be rather difficult because of its brittleness, but the flexibility of PLA can be improved by incorporation of a plasticizer in the material. PLA was plasticized with triacetine (TAc)

Percent ventricular pacing with managed ventricular pacing mode in standard pacemaker population

Aims Unnecessary right ventricular pacing has deleterious effects and becomes more significant when cumulative percent ventricular pacing (Cum%VP) exceeds 40% of time. The Managed Ventricular Pacing (MVP) mode has been shown to significantly reduce the percent ventricular pacing compared to the DDD/R mode. This study assessed the percent of ventricular pacing in a standard pacemaker population pro

Fire resistance of self-compacting concrete, SCC

This article outlines laboratory and full-scale studies on fire resistance of SCC. For this purpose 40 pre-stressed columns and 140 cylinders of concrete were subjected to compressive loading at high temperature. The SCC included water-binder ratios, w/b, between 0.40 and 0.70 and large amount limestone powder. Comparison was done with vibrated concrete, VC, with the same w/b. Mix proportions were
