A fast and sensitive method for the determination of carboxyhemoglobin (COHb) in blood using derivative spectroscopy is described. The addition of sodium dithionite as a reducing agent is not required. The concentration interval studied was from 0.5% to 100% COHb. 相似文献
Carboxyhemoglobin (COHb) levels were determined in stored blood samples from 91 infants diagnosed to have died from the sudden infant death syndrome (SIDS) (0.59+/-0.41%, excluding one outlying value of 10.83%); 48 age-matched controls (0.53+/-0.38%); and three individuals who died from fire related causes (41+/-20%). No statistical differences in COHb levels were detected between blood from SIDS and control infants (p = 0.43). 相似文献
The analysis of burned human remains has been of great interest among forensic anthropologists largely due to the difficulty that their recovery, classification, reconstruction, and identification present. The main purpose of this analysis is to present histological methodology for the interpretation of bones altered by thermal processes. We include analyses of the microscopic changes among bones exposed to different temperatures, with the goal of establishing categories of histological morphology in relation to fire temperature. Samples of bone (ilium) were exposed systematically to controlled temperatures. Analysis of the resulting histological changes has allowed the formation of a clear four‐stage classification of the alterations observed. This classification should prove useful in assessing bone changes in relation to temperature of exposure, particularly in cases where this temperature was previously not known. 相似文献
In the field of global environmental governance, a plethora of international regimes have emerged over the past decades. In some issue areas, multiple regimes aim to govern the issue, sometimes reinforcing, oftentimes conflicting with each other. Consequently, international regime complexes are an empirical phenomenon, which are inherently characterized by specific degrees of fragmentation. For any given issue area, one of the key questions is whether the institutional fragmentation encountered in such regime complexes is synergistic or conflictive in nature. Scrutinizing this question poses methodological challenges of how to delineate a regime complex and how to assess its fragmentation. Drawing on the highly fragmented case of the international forest regime complex, this paper aims to map its institutional fragmentation and to analyse the degrees to which it is conflictive or synergistic. For this we conceptualize the notion of institutional elements and develop a novel method for mapping regime complexes based on their core institutional elements. We then employ tools from the sub-discipline of policy analysis on the complex’s institutional elements for analysing in detail, which of the elements are mutually synergistic and conflictive with other elements of the regime complex. Our results indicate that synergistic relations mostly exist among rather vague elements, often built around sustainability as a core principle. On the contrary, conflictive relations prevail as soon as the elements are designed in more concrete and substantial ways. We conclude that the forest regime complex displays only degree of seemingly synergistic fragmentation through a number of non-decisions and the use of “sustainability” as an empty formula. De facto, conflictive fragmentation prevails among elements of concrete subject matter. This raises questions on whether vast parts of regime complexes merely serve symbolic functions, while conflicts on substance are being camouflaged.
This article analyses the potential for Russian oil export growth through the next decade. It concludes that supply for exports will continue to grow, albeit moderately. The greater or lesser intensity of that growth will depend on the evolution of both production and internal consumption, and especially on the reaction by investors to sector changes promoted by government energy policy. From this analysis, we find three likely scenarios for Russian oil exports. The most positive envisages it will be possible to diversify exports while the most negative suggests that Russia will have scant opportunity to develop an export diversification strategy. 相似文献
In economic voting models, the electorate punishes governments associated with bad economic results and rewards those who provide prosperity. However, citizens do not always place the same weight on economic considerations when deciding their vote. This weight, it is argued, is a function of the degree to which governments can be deemed responsible for domestic economic outcomes. More precisely, the article hypothesises that when the economy is highly vulnerable to external economic conditions (and thus less controllable by the national government), voters will value less the information they receive on the state of the economy, and, as a consequence, electoral behaviour will be less influenced by economic performance. This conjecture is tested empirically using survey data from 15 European countries. Consistently with the prediction, it is found that employment expectations matter more the greater the degree of economic closeness of the country. General economic expectations have an impact on voting regardless of the level of economic openness, and no sign of pocketbook voting is detected. Also, the evidence seems to suggest that the internationalisation of the economy plays an exonerating role only under left-wing governments. 相似文献
