The adsorption and desorption properties of SQD-85 resin for Cu(II) had been investigated. A series of experiments were conducted in a batch system to assess the effect of the system variables, i.e. initial pH, contact time and temperature. The results show that the optimal pH for the adsorption was 5.99 in the HAc-NaAc system, and the maximum adsorption capacity was estimated to 324 mg/g a...

The heterogeneous nuclear ribonucleoprotein (hnRNP) Squid (Sqd) is a highly abundant protein that is expected to bind most cellular RNAs. Nonetheless, Sqd plays a very specific developmental role in dorsoventral (DV) axis formation during Drosophila oogenesis by localizing gurken (grk) RNA. Here, we report that Sqd is also essential for anteroposterior (AP) axis formation. We identified sqd in ...

Heterogeneous nuclear ribonucleoproteins, hnRNPs, are RNA-binding proteins that play crucial roles in controlling gene expression. In Drosophila oogenesis, the hnRNP Squid (Sqd) functions in the localization and translational regulation of gurken (grk) mRNA. We show that Sqd interacts with Hrb27C, an hnRNP previously implicated in splicing. Like sqd, hrb27C mutants lay eggs with dorsoventral de...

BACKGROUND Sleep Quality Disorder (SQD) plays a major role in road accidents. So, this study was carried out to determine the prevalence of SQD among occupational drivers using systematic review and meta-analysis in Iran. METHODS All Persian and English articles between January, 2000 and October, 2015 which had reported the SQD prevalence in Iranian drivers by Pittsburgh Sleep Quality Index (...

INTRODUCTION Aim of this study was to implement and validate the Italian version of the Screening Questionnaire for Disaster Mental Health (SQD), a tool for the screening of post-traumatic stress disorder (PTSD) and depression in the long-term aftermaths of a natural disaster. METHODS A convenience sample of 116 subjects living in L'Aquila after the 2009 earthquake were administered the SQD a...

In this paper, we review the investigation for the light-matter interaction between surface plasmon field in metal nanoparticle (MNP) and the excitons in semiconductor quantum dots (SQDs) in hybrid SQD-MNP system under the full quantum description. The exciton-plasmon interaction gives rise to the modified decay rate and the exciton energy shift which are related to the exciton energy by using ...

In this communication, we study the optical response of a semiconductor quantum dot (SQD) coupled with a metal nanoparticle (MNP). In particular, we explore the relationship between the size of the constituents and the response of the system. We identify, here, three distinct regimes of behavior in the strong field limit that each exhibit novel properties. In the first regime, we find that the ...

Abstract The influence of the plasmon three spherical metal nanoparticles (MNPs) on semiconductor quantum dot (SQD) having external fields is analyzed. density matrix equations are modified for description optical properties SQD-MNPs nanosystem. We study theoretically role plasmon–exciton dipole coupling in investigate dependence nanosystem position MNPs with respect to SQD as well material par...

Based on cavity quantum electrodynamics (QED), we investigate the light-matter interaction between surface plasmon polaritons (SPP) in a metal nanoparticle (MNP) and the excitons in semiconductor quantum dots (SQDs) in an SQD-MNP coupled system. We propose a quantum transformation method to strongly reveal the exciton energy shift and the modified decay rate of SQD as well as the coupling among...
