Review of technology in small-scale biomass combustion systems in the European market

This work studied the importance of wood pellets, chips and wood logs for small- and medium-scale heat production. Pellet use can contribute substantially to reaching the renewable heat and electricity goals set by the European Union (EU) Renewable Energy Directive. Consequently, to integrate into European energy markets, pellet use must be a key piece of the EU energy policy.This study provides a wide perspective on the state-of-the-art small-scale biomass combustion units, particularly those that use pellets for fuel. Small-scale combustion units include stoves and boilers with capacities less than 200 kW. A wide market review has been conducted, including a review of the literature and information from manufacturers and test institutes. A database has been created, which includes 186 companies and offers 995 different models, providing an extensive view of the European market. The large number of new companies shows that the solid-fuel boiler market is continuously increasing across Europe. The technologies that are currently the most widely used are described and compared.     

Myocardial revascularization with one and two mammary arteries: clinical results and long-term follow-up

The manufacturing process for albumin in Australia is based primarily on ion-exchange chromatography. The capacity of ion-exchange matrices to remove non-enveloped viruses (canine parvovirus and poliovirus type 1) was assessed using a scaled-down chromatographic process which was shown to yield product meeting purity criteria set for the manufacturing process. Poliovirus type 1 and canine parvovirus were added at one tenth the volume of desalted and delipidated Supernatant II + III produced by traditional Cohn Fractionation from human plasma before the material was applied to DEAE and CM ion-exchangers connected in series. Samples were taken at equilibration, wash, elution and regeneration steps and the log clearance and reduction of the viruses calculated. The mean clearance and reduction factors for viral load of poliovirus type 1 were 5.3 logs and 3.2 logs, respectively and 1.8 logs and 1.8 logs for canine parvovirus.     

What are entrepreneurial dietitians charging? The Consulting Dietitians Network National Fee Survey.

To respond to a need to develop a national fee guideline, the Consulting Dietitians Network conducted a membership fee survey. A questionnaire requesting fee information for various nutrition consulting services was distributed to members as an insert with the Consulting Dietitians Network quarterly newsletter and by electronic mail. The response rate was 38.4% (98 respondents) and most respondents (74.5%) had urban practices. The most frequently charged fees (mode) for individual counselling ($75/hour), industry and commercial firm consultations ($150/hour), group facilitation ($150/hour), and media consultations ($150/article) were highest in the region of Ontario, Quebec, and the Atlantic provinces. The most frequently charged fees (mode) for home visits ($100/hour), writing for newspapers ($250/hour), and menu reviews ($60/hour) were highest in the region of Saskatchewan and Manitoba. The minimum and maximum fees were significantly different for the three regions (Ontario, Quebec, and the Atlantic provinces; Manitoba and Saskatchewan; and Alberta, British Columbia, and Yukon Territory) studied for initial client consultations, industry and commercial firm consultations, and menu reviews (p<0.05). For home visits, teaching in an institution, seminar presentations, group facilitation, media consultations, and writing media articles, the differences in the minimum and maximum fees charged were highly significant (p<0.001). Entrepreneurial dietitians may use these data as a reference to establish and negotiate consultation fees.     

Physical restraints in nursing homes: a review of the literature since the Nursing Home Reform Act of 1987

The use of physical restraints is one of the most negative features of nursing home care. Their use significantly affects the quality of life of residents. In an attempt to limit the use of restraints, the Nursing Home Reform Act (NHRA) of 1987 contained provisions regulating their use. In this article, the authors review the literature on the use and consequences of physical restraints in nursing homes since the passage of the NHRA. First, they describe the history behind the use of restraints and define what is considered to be a physical restraint. Second, they examine the four most common justifications for restraint use. Third, they describe the incidence and prevalence of restraint use. Fourth, they address demographic and clinical characteristics of residents that have been found to be associated with restraint use. Fifth, they examine negative outcomes of restraining residents. Finally, they describe alternatives to using restraints.     

Spontaneous coronary artery dissection

The effect of an intra-luteal injection of the 5-lipoxygenase (5-LO) inhibitor BWA4C (2 mg in 50 microl DMSO) on the secretion of oxytocin (OT) from the corpus luteum in response to a close-arterial infusion of prostaglandin (PG)-F2alpha (5 ng min(-1)) was examined in anaesthetised sheep. Within 30 minutes of administration both basal (pre-infusion) and PGF2alpha-stimulated OT release into the posterior vena cava were significantly (P<0.01) reduced. These results are consistent with the proposition that 5-LO products of arachidonic acid may modulate OT secretion from the ovine corpus luteum.     

Prevalence, clinical correlates, and treatment of hypertension in elderly nursing home residents. SAGE (Systematic Assessment of Geriatric Drug Use via Epidemiology) Study Group

BACKGROUND: Hypertension is prevalent in the elderly, but an information gap remains regarding the old, frail, individuals with complex conditions living in long-term care. OBJECTIVE: To analyze the patterns of antihypertensive drug therapy among elderly patients living in nursing homes to elucidate their conformity with consensus guidelines. SUBJECTS AND METHODS: We used a long-term care database that merged sociodemographic, functional, clinical, and treatment information on nearly 300000 patients admitted to the facilities of 5 US states between 1992 and 1994. RESULTS: Hypertension was diagnosed in 80206 patients (mean age, 82.7+/-7.8 years). The prevalence was higher among women and among blacks. About one fourth of patients had 6 or more comorbid conditions; 26%, 22%, and 29% had concomitant diagnoses of coronary heart disease, congestive heart failure, and cerebrovascular disease, respectively. Seventy percent of patients were treated pharmacologically. Calcium channel blockers were the most common agents (26%), followed by diuretics (25%), angiotensin-converting enzyme inhibitors (22%), and beta-blockers (8%). The relative use of these drugs changed according to the presence of other cardiovascular conditions. Adjusting for potential confounders, the relative odds of receiving antihypertensive therapy were significantly decreased for the oldest subjects (> or =85 years old: odds ratio, 0.85; 95% confidence interval, 0.81-0.89) and those with marked impairment of physical (odds ratio, 0.77; 95% confidence interval, 0.73-0.81) and cognitive (odds ratio, 0.67; 95% confidence interval, 0.64-0.70) function. CONCLUSIONS: Among very old, frail hypertensive patients living in nursing homes, the pattern of treatment seems not to follow recommended guidelines; age, functional status, and comorbidity appear to be important determinants of treatment choice.
