constant cough and pain in the chest had been present for five months. On my first visit to the wards after the boy's admission, I found him sitting up in bed, breathing rather rapidly, but not seeming much distressed, and in the act of expectorating purulent sputum into a receptacle already nearly full. On physical examination there appeared to be no flattening or falling in of the chest on ei...

On the 1st January, 1931, a boy, six years of age, became ill with sneezing, indefinite malaise and slight backache. There had been no previous illness. On the evening of the second day he passed, per urethram, without pain, what was thought to be pure blood. I saw him at 8.30 p.m. and found him in bed with a temperature of 101'4? F. and a pulse-rate of 112. The pharynx and nose were congested,...

A new monotypic Theraphosidae genus, Kankuamo Perafán, Galvis & Pérez-Miles, gen. n., is described from Colombia, with a new type of urticating setae. These setae differ from others principally by having a small distal oval patch of lanceolate reversed barbs. Males of Kankuamo gen. n. additionally differ by having a palpal bulb organ very divergent from all known species, with many conspicuous ...

Advocates of biomimicry encourage a new industrial paradigm that ostensibly leaves behind the crude violence of Francis Bacon, the domination of nature-as-machine, and a history of toxic production processes that have given rise to a present and coming climate crisis. As part of a broader trend towards the conceptualization and development of a ‘bioeconomy’, we argue here that biomimicry produc...

Staining of thin sections results in greater contrast which facilitates focusing and the observation of fine structure. Lead hydroxide, as suggested by Watson (1), has become increasingly popular as a stain for electron microscopy. However, when lead hydroxide is exposed to the carbon dioxide of air, lead carbonate forms and is deposited on the sections as fine, needle-like crystals, large amor...

Motivated by the relatively wide range of values published hitherto, we offer a new, reliable method for determination of manganese in hair from unexposed human subjects. By using a mini-autoclave, we have developed a method that obviates loss of manganese during digestion and, thanks to use of a Teflon receptacle and rigorous methodology, contamination has been minimized. We used Zeeman flamel...

The Moroccan coast corresponds to a space of intense economic activities (industrial, agricultural, domestic,...etc), and thus constitutes the receptacle significant quantities substances natural or anthropic origin, many which possess toxic properties. Heavy metals are pollutants whose harmfulness is related their persistence speciation. They poorly metabolized, so they can be transferred food...
