Stress territorialism

Flow through moderately severe coronary artery stenosis is commonly normal at rest but becomes inadequate for the increased metabolic requirements and blood flow during stress. Coronary blood flow normally increases to four times resting baseline flow rates after coronary artery vasodilators such as dipyridamole and adenosine. A stenosis restricts maximal blood flow capacity compared to normal coronary arteries, thereby causing a disparity in regional perfusion of areas supplied by a stenotic artery compared to normal coronary arteries. This disparity manifests as a relative perfusion defect during stress, corresponding to the ischemic myocardial territory supplied by a stenotic artery. Furthermore, the quantitative severity of the relative perfusion defect is proportional to the severity of the stenosis under conditions of maximal coronary flow after dipyridamole or adenosine stress [24]. [Pg.15]

It should be stressed, then, that since patents in this area are being issued in other countries, such as the United States and various European countries, it is advisable to evaluate the territory suitable for seeking protection. [Pg.382]

As human beings, we re not the only creatures who respond very badly to stress. Hans Selye, a Canadian researcher credited with being the father of the study of stress, used ordinary house mice as his test subjects. As his mouse population grew in a confined space, males fought more aggressively over territory, sometimes to the death. And females ceased to reproduce. [Pg.97]

In summary Our familiar three-dimensional reality is called the "middle world" in the Shamanic model. Both the lower and upper worlds are internal dimensions which are entered via altered states of consciousness. Because hyperspace is perpendicular to ego-awareness, consciousness is the bridge which links all of the worlds together. Access to these inner dimensions is dependent upon many factors. Everyone enters them while dreaming, but hypnosis, meditation, severe stress and many other catalysts, including psychedelic drugs, can also provide admittance. For the purposes of this book, we will concentrate on conscious Shamanic intent in conjunction with psychotropic plants as our method of entry into hyperspace. But first, having differentiated the territory, we must further examine its structure and contents. [Pg.62]

A complex analysis of the systematic data on atmospheric air pollution in Tashkent and of the development in the industrial stracture and traffic has made it possible to assess in general the spread of the technological stress over the city territory (Figures 1, 2). [Pg.384]

Laboratory studies on rats have shown that rats raised under crowded conditions exhibited perverse and antisocial behavior (Booth, 1976). The incidence of aggressive episodes increased markedly, which tended to stress the entire community. Those rats that were the most hardy avoided stress by establishing territories in areas that were easiest to protect. Some of the rats engaged in... [Pg.325]

Also, the enany was not to enter French territory again and destroy precious parts of it, like in 1914-1918. As trench warfare had been a French victory ( the line had held ) but a very costly one, a new, well-prepared, modem trench line directly at the border had to be created the Maginot Line, simultaneously stressing the Frenchness of the returned provinces of Alsace and Lorraine. The French army invested in concrete, guns and strong defence lines. [Pg.18]

By the analysis of Table 7, we can see that Coimbra is the municipality that has a town with the lowest level in terms of capability support, due to its low score in factor 1 - water system performance. In Table 8 we can observe that Coimbra presents a deep territorial contrast in terms of capability support, in opposition with Fundao, and Proenpa-a-Novamunicipalities. The results of the Almeida municipality stress the relevant capability support in five towns, deriving from its high score in factor 1. [Pg.452]

In many habitats, particularly in the tropics, the most abundant ants are dominants, that is, they exclude other dominants, and normally have semipermanent territories. It is not yet known whether the interspecific territory boundaries are marked by exocrine chemicals, but this seems entirely possible. Since interspecies fighting is probably no more common than fighting between colonies of the same species, it is likely that mechanisms exist to reduce direct aggression. The importance of the dominant ants in determining the insect fauna within their territories has been stressed (e.g., Leston, 1978) particularly with reference to tropical tree crops, where the presence or absence of various pests is often strongly associated with particular dominants. [Pg.448]

National, province, state or territory acts, regulations, codes of practice, rules, standards, and guidance notes on occupational exposure standards (chemical and pliysical), noise, lighting, hazardous substances, heat and cold stress, and ionizing and non-ionizing radiation. [Pg.448]

Hemodynamic stress can be mimicked by using a tolerance test such as acetazolamide administration in conjunction with quantitative measurement of CBF. Although the exact mechanism of action is uncertain, acetazolamide causes vasodilatation of normal cerebral arteries and an increase in CBF in the corresponding territory. Patients with impaired cerebrovascular reserve, however, are aheady maximally vasodilated due to the response of cerebral autoregulatory mechanisms, and thus cannot respond further to acetazolamide. CBF does not increase, but remains stable or even decreases, because of a steal phenomenon by the healthy arteries (Nariai et al. 1995). Acetazolamide is generally well tolerated, with the most common side effects being cir-cumoral numbness, paresthesias, and headache. One case of acetazolamide-associated reversible ischemia has been reported (Komiyama et al. 1997). [Pg.115]

Caesar s account of the flight of Ambiorix s followers also stresses again the border status of the Ardennes - Theis places were knowen to the borderers - and in, 45 You Like It Rosalind reminds us of this when she says that an old religious uncle of mine taught me to speak, who was in his youth an inland man (3.2.335-7) inland in this context seems to imply that the supposed uncle had in the past lived well within the borders of a territory, as opposed to the peiipheiy in which Rosalind and Orlando now find themselves. [Pg.96]
