In the closing decades of the nineteenth century, natural history museums established solid communication networks, and their different audiences formed what became known as the 'museum movement'. It was within this context of exchange that William H. Flower made his 1889 speech on the roles natural history museums should play. The article analyzes his influence on Argentina's Museo da La Plata...

Animal models provide vital tools to explicate the pathogenesis of atherosclerosis. Accordingly, we established two atherosclerosis-prone mice models: (i) mice lacking the LDL (low-density lipoprotein) receptor (LDLR) and the ability to edit apo (apolipoprotein) B mRNA (Apobec1; designated LDb : LDLR-/- Apobec1-/-), and (ii) mice with the LDb background, who also overexpressed human apoB100 (de...

The genus Euthycaelus Simon 1889 is diagnosed based on the examination of type-material and additional material from Venezuela and Colombia. The genus now includes: Euthycaelus colonicus Simon 1889, E. norae sp. nov., E. amandae sp. nov.; Euthycaelus steini Simon 1889 is transferred to Psalistops comb. nov. The genus Schismatothele Karsch 1879 is considered a senior synonym of Hemiercus Simon 1...

Network computing seeks to utilize the aggregate resources of many networked computers to solve a single problem. In so doing it is often possible to obtain supercomputer performance from an inexpensive local area network. The drawback is that network computing is complicated and error prone when done by hand, especially if the computers have diierent operating systems and data formats and are ...
