In this work we report on the design, microfabrication and analytical performances of a new electrochemical sensor array (ESA) which allows for the first time the simultaneous amperometric detection of nitric oxide (NO) and peroxynitrite (ONOO ), two biologically relevant molecules. The on-chip device includes individually addressable sets of gold ultramicroelectrodes (UMEs) of 50 mm diameter, ...

PURPOSE To document incidence of and risk factors for development of retinopathy of prematurity (ROP) in a population of low birthweight infants (< 1500 g). METHODS The authors registered clinical characteristics (birthweight, gestational age (GA), Clinical Risk Index for Babies (CRIB), Apgar score, respiratory characteristics (intubation, ventilation, respiratory support, supplemental oxygen...

In this article we shall present an overview of the development of calculus in Indian mathematical tradition. The article is divided naturally into two parts. In the first part we shall discuss the developments during what may be called the classical period, starting with the work of Āryabhat.a (c. 499 CE) and extending up to the work Nārāyan. a Pan.d. ita (c. 1350). The work of the Kerala Scho...

2014 The heat capacity of biphenyl has been measured between 10 and 50 K. Although no specific heat anomalies could be seen at 15 or 40 K, where phase transitions are known to exist, the results are not inconsistent with a transition enthalpy smaller than 10 J.K-1. mol-1 at 40 K. At this temperature, the thermal equilibrium times changed abruptly. J. I’lij,si(lue LETTRES 41 (1980) L-83 L-85 15 ...
