Competitive breath-hold divers try to achieve maximum times, depths, or distances underwater, thereby risking hypoxic syncope. In the present study, the cardiorespiratory responses to dynamic apnea (simultaneously initiated apneas and dynamic leg exercise) were investigated in 10 breath-hold divers. The divers performed 60 s dynamic apneas with the face in air (A) or face immersed in cold water (A

By comparing the phenotypic (P) variance-covariance matrices between closely related taxa or conspecific populations, one can study the outcome of the interplay between selection and developmental constraints in phenotypic evolution. Shared patterns of phenotypic integration are also of interest and might result from similarities in either selection or developmental pathways. We compared P-matrice

The most common loop in an industrial plant is a SISO-loop with a PI(D)controller. If the loop is affected by disturbances,these can be handled by adding a feedforward control action. In an industrial control system there are many measured signals, apart from those of the loop, available. The question we address in this article is how to select the feedforward variable out of the available measure

The atmospheric deposition of PCB within the catchment areas of an oligotrophic lake and an eutrophic lake in southern Sweden resulted in a flow of about 1 mg PCB.m(-2).year(-1) to the lakes. The sedimentation of the pollutants in the lakes (measured by sediment traps) was 110 and 52 mg PCB.m(-2).year(-1) for the oligotrophic and eutrophic lakes, respectively. The concentration of pollutants in pl

Case studies have claimed that private consumption growth is higher during fiscal contractions due to the very fact that government spending is cut. Indeed, neoclassical theory has this implication. This paper uses regression analysis of a panel of 19 OECD countries and shows that this is not true in general. On the contrary, contraction (expansion) periods experience lower (higher) private consum

BACKGROUND: Positron emission tomography (PET) provides metabolic information of tissues in vivo. The purpose of this study was to assess the value of PET with 2-[(18) F] fluoro-2-deoxy-D-glucose (FDG) in prediction of therapy outcome (tumor response, survival, and locoregional control) in locally advanced HNSCC. METHODS: Between 1993 and 1999 47 patients underwent PET before (PET(1)) and after (P

Novel molecularly imprinted polymer systems utilizing 4-vinylpyridine and 1-vinylimidazole as functional monomers have been developed for enantioselective recognition of carboxylic and N-protected amino acids. Non-covalent interactions between the functional monomers and the template molecules were the source of the subsequent recognition sites in the resultant polymers. The capacity of the polyme

High-resolution palynofloral signatures through the Cretaceous-Palaeogene boundary succession show several features in common with the Permian-Triassic transition but there are also important differences. Southern Hemisphere Cretaceous-Palaeogene successions, to date studied at high resolution only in New Zealand, reveal a diverse palynoflora abruptly replaced by fungi-dominated assemblages that a

1. Salmeterol is a potent, selective and long acting beta 2-adrenoceptor agonist. In vitro, salmeterol exerts 'reassertion' relaxation of airways smooth muscle. Reassertion relaxation refers to the capacity of salmeterol to cause repeated functional antagonism of induced contraction when airway smooth muscle is intermittently exposed to, then washed free from, beta-adrenoceptor antagonists such as

The issue of word stress has not been the subject of any detailed analysis in traditional works on Romanian. It is generally assumed that stress is not predictable. The generalizations that have been made concerning stress placement are, however, made on the basis of observations of surface forms. Mallinson 1987:300 says that “stress is free and variable, giving rise to doublets: m'odele ‘the fash

Hur ska en högre utbildning i säkerhetsledning se ut? Ska den ha utgångspunkt i teknik och problemlösning, ekonomi och management, kriminologi och beteendevetenskap eller kanske juridik? Här är del två i artikelserien om professionaliseringen av säkerhetsarbetet. Nu handlar det om möjligheter och utmaningar för en akademisk utbildning kring säkerhetsledning.

Abstract in Chinese 中文语用标记语"吧"的关联理论分析 Marita Ljungqvist 瑞典隆德大学 摘要 本文以关联理论为依据试图对汉语句末助词”吧”的用法进行全面的解释与分析。 结果表明，”吧” 在陈述句、疑问句与祈使句都具有类似的用法，即表示说话者面向听话者对自己表达的命题(陈述句、疑问句) 或言语行为(祈使句)之承诺。结果还表明”吧”有时同英文的像 yeah 、right 、innit 类似的所谓”tags” 的词语一样 起着鼓励听话者更积极/投入地参加会话的作用。 在这种语境里”吧”的出现表示礼貌而不一定意味着说话者要听话者回应或确认命题的真实价值。 关键词 句未助词、语用学、关联理论This paper aims to present a proposal for a relevance-theoretic description of the use of the particle ba in Mandarin Chinese. The result of the analyses of the data shows that ba is a pragmatic marker with a similar function in declaratives, interrogatives and imperatives, i.e. to indicate hearer-oriented weak commitment towards either the proposition expressed (declaratives, interrogatives) or t
