The wet tropical forest is, on the whole, a unique ecosystem in the world that is known to house the absolute highest number of species of both plants and animals. In this regard, it is enough to stress that the total number of flowering plant species currently known around the world is ~250 000, of which ~90 000 are of the rain forests of South America and Central America, and ~30 000 are of t...

Glyoxylate dehydrogenase (glyoxylate:NAD+ oxidoreductase) was purified 600-fold in three steps from crude extracts of the fungus Sclerotium rolfsii (Corticium rolfsii Curzi). Two of the purification steps involved dye-affinity chromatography. The enzyme is a tetramer of Mr 250 000, with identical subunits of Mr 57 000. Inhibition studies suggest that there is one essential thiol group per activ...

Data from the annual general report of the Venereal Disease Control Centre (VDCC) in a state with a population of approximately 1 250 000 people (in 1977), of whom about 1 100 000 live within 25 miles of the centre of Adelaide, the capital city, are presented.

Two forms of Ca2+-dependent cysteine proteinase (calpain, EC 3.4.22.17) and their specific endogenous inhibitor (calpastatin) were partially purified from porcine retina: calpain I (low-Ca2+-requiring form) was half-maximally activated at 8 microM-Ca2+, and calpain II (high-Ca2+-requiring form) at 250 microM-Ca2+. Both calpain I and calpain II were inhibited by calpastatin. Calpain I from porci...

Laying out the logic of Bourdieu’s approach to institutional fi elds, this essay argues that Bourdieu’s theorization of the logic of practice is a generic contest for domination in a plurality of homologously organized fi elds. Bourdieu aligns all practices through the logic of domination, which allows him to homologize group relations in every fi eld. This homologization depends on a homogeniz...

Sudden cardiac arrest (SCA) is recognized as a serious public health problem, accounting for 250 000 to 300 000 deaths per year; it is now the third-leading cause of death behind cancer and nonsudden cardiovascular deaths.1,2 Immediate, well-performed cardiopulmonary resuscitation (CPR) and early defibrillation are the only out-of-hospital interventions that improve outcomes.3 The chain of surv...

Some gastropod specimens belonging to the planorbid genus Ferrissia were recently collected in Lebanon and in Iraq, where the autochthonous species Ferrissia clessiniana (Jickeli, 1882) is supposed to occur. The molecular identification of collected specimens proved that they belong to the allochthonous species Ferrissia fragilis (Tryon, 1863), the protagonist of a dramatic cryptic invasion whi...

We describe algorithms for polynomial factorization over the binary field F2, and their implementation. They allow polynomials of degree up to 250 000 to be factored in about one day of CPU time, distributing the work on two processors.
