Water for Life Strategy in Alberta: Changing Priorities in Canadian Water Policy?
No full textWater resources are being stretched to the limit in Alberta and irrigation activities account for more than 70 percent of consumptive water use in the province. Conflicts among users and potential users may be looming. Pollution of surface water and groundwater and outbreaks of water-borne pathogens have been increasing. Freshwater systems are likely to deteriorate further with impending climate change. Following passage of the Alberta Water Act in 1999 and the Irrigation Districts Act in 2000, which allowed limited transfers of water among water users, the Alberta government issued its Water for Life Strategy in late 2003. The strategy’s principal goals include (1) evaluation of the use of economic instruments to manage water demand by 2007; (2) demonstration of best management practices by 2010; and (3) a 30 percent increase in productivity and efficiency over 2005 levels by 2015. This seems to presage a new era in water management in Alberta, but will the necessary changes in water management be forthcoming? This study examines the need for demand-based management and the constraints that make effective changes in water policy problematic. Evidence from a recent study in the St. Mary’s River Irrigation District highlights problems with water markets.Environmental Economics and Policy,
Cylindruria
No full textThe morphological analysis of urine sediment is an essential part of urinalysis and casts are important elements of urinary sediment. Their shape is typically cylindrical, with extremities often rounded. Casts form within the renal tubules and are made of Tamm-Horsfall glycoprotein (THG). Under some physiological or pathological conditions THG fibrils aggregate giving rise to casts, whose formation is favoured by a number of factors including high urine osmolality and/or low pH. Casts can be found in normal subjects, in non-renal conditions, such as fever, dehydration, and acute heart failure as well as in virtually all renal diseases. Casts can be classified on the basis of their morphology as hyaline, granular, waxy, fatty, cellular (leukocytic, erythrocytic, epithelial), containing crystals or microorganisms, pigmented and mixed. As the correct identification of casts is crucial for an accurate and timely diagnosis of renal disorders, laboratory professionals should be trained to identify and classify casts properly
Pollution Control Legislation in Alberta
No full textThe author provides brief outline of pollution control legislation in Alberta and Us effect upon the oil and gas industry. The Department of the Environment discharges its obligation of "regulating"environmental matters through various sources of legis lation which allow for flexible regulatory scheme adaptable to changing govern ment policy. Direct regulation of the industry is achieved by requiring compliance with the regulations prior to the issue of licenses and permits. Further, various "Guidelines\u27 for pollution control are being established and incorporated into such permits and licences. The author also provides list of similar legislation existing in British Columbia, Saskatchewan, and Alberta
Biological Diversity and Alberta Law
No full textBiological diversity refers to the rich variety of all life forms presently on Earth. It is important to preserve and maximize biological diversity, because of its intrinsic value and its value to human survival and wellbeing. In order to do so, the author argues, a broad ecosystem management approach to species conservation is necessary.
Numerous Alberta statutes are examined comprehensively to determine their effects and potential effects on biological diversity. The ecosystem management approach to species conservation is not prominent in Alberta law. Outside of National Park land, very little of Alberta\u27s area offers protection for biological diversity. While the administration of some Acts (such as the EPEA and the Natural Resources Conservation Act) shows promise, a lack of specific duties permits decisions adverse to biological diversity. Changes to Alberta\u27s planning legislation may be beneficial, through the regulation of development on private land. Because of the prime importance given to economic development in various Alberta statutes, the possibility exists for significant adverse impacts to biological diversity. The author recommends a number of legal reforms. These include the addition of explicit purpose sections in relevant legislation, the imposition of a positive duty on decision-makers to consider sustainability and biological diversity, and the creation of incentive programs to encourage private property owners to set aside habitat areas
Water rights in Alberta
No full textThe author studies the law in Alberta regarding the use of water resources. The right to divert surface water from its course or to detain its natural flow for consumptive or other purposes is discussed. The author contends that the present Alberta Water Resources Act does not develop maximum beneficial use of Alberta's water resources
Identificazione casuale di atrofia gastrica severa con macrocitosi complicata da sindrome coronarica acuta
No full textChronic atrophic gastritis (CAG) and gastric cancer are leading causes of morbidity and mortality worldwide. Serum pepsinogens have been used as biomarkers of gastric mucosa status, including gastric inflammation, so that they might be useful for detection of gastric atrophy or gastric neoplasm at an early stage. Serum pepsinogen 1 and pepsinogen 2 concentrations are known to increase in the presence of Helicobacter pylori-related non-atrophic chronic gastritis, and the eradication of this pathogen is associated with a significant decrease in their values. We describe here the case of an asymptomatic 60 years old man, with a casual serological diagnosis of severe gastric atrophy, macrocytosis and severe complications, culminating in an acute coronary syndrome. This case report raises some important considerations, such as the fact that CAG could not be correctly and early diagnosed and that it may be misleadingly regarded as a rare condition, whereas its prevalence is conversely largely underestimated. This may lead to severe complications that may include gastric malabsorption and vitamin B12deficiency, along with gastrointestinal, neurologic, psychiatric, cardiovascular, cerebral and peripheral vascular disorders
Utilità di una nuova procedura immunologica manuale e rapida per la diagnosi di infezione da Plasmodium falciparum

No full textPricing of Alberta\u27s Oil
No full textThe history, functions and scope of the Alberta Petroleum Marketing Commission are studied. In addition, the practices and procedures of the A.P.M.C. are discussed, especially the pricing and marketing aspects. Finally, the Petroleum Administration Act is looked at in some depth. The Edmonton Terminal Price, Export Tax and the enforcement of the Petroleum Administra tion Act are dealt with by the author
