Annually laminated stalagmites can be used to construct a precise chronology, and variations in laminae thickness provide an annual growth-rate record that can be used as a proxy for past climate and environmental change. Here, we present and analyse the first composite speleothem annual growth-rate record based on five stalagmites from the same cave system in northwest Scotland, where precipit...

Cardiolipin (CL)-specific fluorescent dye 10-N-nonyl-acridine orange (NAO) was used to visualize CL distribution in Escherichia coli cells of different phospholipid compositions. In a filamentous mutant containing only anionic phospholipids, green fluorescent spots were observed along the filaments at approximately regular intervals. Three-dimensional image reconstruction obtained by optical se...

We present NaOISIS, a three-dimensional behavioural simulator for the NAO humanoid robot, aimed at designing and testing physically plausible strategic behaviours for multi-agent soccer teams. NaOISIS brings together features from both physical three-dimensional simulators that model robot dynamics and interactions, and two-dimensional environments that are used to design sophisticated team coo...

This paper presents a new approach to designing and supervising an interactive experience. The approach is implemented by creating a serious game with a Nao robot. This game allows youth to discover the ethnographic artifacts of La Rochelle’s natural history museum in a playful manner. The design phase of the game is divided into two steps. The first step defined the atomic behaviors grouped wi...

The Granger causality test is used to examine the effects of the El Niño–Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO), and the North Atlantic Oscillation (NAO) on global dry/wet conditions. The results show robust relationships between dry/wet conditions and the ocean states, as assessed through a multi-index (standardized precipitation evapotranspiration index and standar...

The crystal structure of SrNa(2)(P(2)S(6))·8H(2)O is isotypic with that of its calcium analogue. The asymmetric unit consists of one Sr(2+) cation (2 symmetry), two Na(+) cations (2 and symmetry, respectively), one-half of a centrosymmetric (P(2)S(6))(4-) anion with a staggered confirmation and four water mol-ecules. The crystal structure is built up from layers of cations and anions extending ...

In this paper we discuss the atmospheric dynamics of the North Atlantic Oscillation (NAO), the zonal index, and annular patterns of variability (also known as annular modes). Our goal is to give a unified treatment of these related phenomena, to make explicit how they are connected and how they differ, and to illustrate their dynamics with the aid of an idealized primitive equation model. Our f...

in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...

The North Atlantic Oscillation (NAO) is one of the major sources of interannual atmospheric variability over the Northern Hemisphere. In this study, we examined the variability of lake-levels of Lake Bey ehir in timescale (period) domain using continuous wavelet transform (CWT) and global wavelet spectrum (GWS). The long winter (December, January, February and March) lake-level series and NAO i...
