A Neotropical rove beetle, Piestus heterocephalus Fauvel, 1902 (Coleoptera, Staphylinidae, Piestinae), is redescribed and illustrated. Its abdominal defensive gland complex is described using drawings, photos and scanning electron micrographs. This complex is reported for the first time in Piestinae and its distinctive position is unique in Staphylinidae. Our preliminary survey suggests that th...

This memo contains a table of commonly occurring headers in headings of e-mail messages. The document compiles information from other RFCs such as RFC 822, RFC 1036, RFC 1123, RFC 1327, RFC 1496, RFC 1521, RFC 1766, RFC 1806 and RFC 1864. A few commonly occurring headers which are not defined in RFCs are also included. For each header, the memo gives a short description and a reference to the R...

The purpose of this study is to explore the complex nature of Singapore teachers’ beliefs about knowledge and learning and how these beliefs influence pedagogical practices in their classes. This paper presents findings from a large-scale survey study with 1806 teachers in Singapore. Data revealed that while teachers’ beliefs about pedagogies, knowledge and learning were largely consistent, the...

Siméon-Denis Poisson was 25 years old when he appointed Professor of Mathematics at the École Polytechnique in 1806. Elected to Paris Académie des Sciences six later, soon became one its most influential members. The origin and later developments many concepts mathematics physics that bear his name make interesting stories, a few which we shall attempt sketch this paper.

Apollinaire Bouchardat is regarded as the founder of the field of Diabetology. His contributions to the field include the first known recommendations for specific diets for the management of Diabetes Mellitus and his emphasis on patient education and self-monitoring. He was moreover a great pharmacist as well as a distinguished physician and biochemist.

We first review on the peculiar characteristics of the bursting and flaring activity of the Soft Gamma-ray Repeaters and Anomalous Xray Pulsars. We then report on the properties of the SGR 1806-20’s Giant Flare occurred on 2004 December 27th, with particular interest on the pre and post flare intensity/hardness correlated variability. We show that these findings are consistent with the picture ...

In this figure , a vinylene‐linked covalent organic framework (V‐COF‐1) was integrated with multi‐walled carbon nanotubes (MWCNTs) to contrive modified electrode (V‐COF‐1/MWCNTs/SPCE) for electrochemical sensing applications. The sensor exhibited the simultaneous detection of tryptophan (Trp), uric acid (UA), and 8‐hydroxy‐2′‐deoxyguanosine (8‐OHdG) in biological samples. More details about wil...
