From an analysis of trace element abundances in lunar soils, the influx of meteoritic mass into the lunar surface has recently been estimated by Keays et al. (1) as 3.8 X 10-9 gcm-2 yr-1 and later by Ganapathy et al. (2) as 4 X 10-9 g cm-2 yr-1. I shall show in this note that these numbers are in agreement with independent estimates of the mass distribution for cometary meteoroids. Using the re...

OBJECTIVE This study aimed to compare the effects of a low-intensity face-to-face therapy provided by a trained paediatrician to an intensive group therapy provided by a multidisciplinary team on the BMI of adolescents with obesity. METHODS This longitudinal cohort study included 233 adolescents aged 11-18 years (mean 13.1 ± 1.7 years). Patients and their parents choose either a low-intensity...

We have investigated the characteristics of a silicon oxynitride/silver/silicon oxynitride [SiON/Ag/SiON] multilayer passivation grown using a specially designed roll-to-roll [R2R] sputtering system on a flexible polyethersulfone substrate. Optical, structural, and surface properties of the R2R grown SiON/Ag/SiON multilayer were investigated as a function of the SiON thickness at a constant Ag ...

Background and Aim: We have previously presented analyses of data obtained from the German Perinatal Survey for the years 1995-1997. Here we present an analysis of data from the years 2007-2011 and compare the data to the previous data from the 1990s. Material and Methods: For the years 1995-1997, the data on 1 815 318 singleton pregnancies were provided by the Chambers of Physicians of all the...

In Indian villages with high malaria endemicity use of nylon bednets treated at 25 mg/m2 at 6-month intervals for 3 years caused significant reductions in malaria incidence, slide positivity rate, slide falciparum rate, annual parasite index, and parasite rate in the entire population, as well as reductions in rates of splenomegaly and anemia in children. In villages with untreated nets, consid...

INTRODUCTION We examined whether obesity at ages 50, 60, and 70 years is associated with subsequent dementia. Changes in body mass index (BMI) for more than 28 years before dementia diagnosis were compared with changes in BMI in those free of dementia. METHODS A total of 10,308 adults (33% women) aged 35 to 55 years in 1985 were followed up until 2015. BMI was assessed six times and 329 cases...

Nowadays, MVNOs are entering the market with the aim of providing new services in the mobile telecommunications industry. Current studies show that having an active and sizable mobile communications market, owning the necessary technological infrastructure, and developing the imperative regulations are critically important factors for MVNO market development. In this respect, this study aims to...

The environmental performance of presently operated GSM and UMTS networks was analysed concentrating on the environmental effects of the End-of-Life (EOL) phase using the Life Cycle Assessment (LCA) method. The study was performed based on comprehensive life cycle inventory and life cycle modelling. The environmental effects were quantified using the IMPACT2002+ method. Based on technological f...

The fluorescence and phosphorescence of 2,2'-bis(5-phenyl-1,3,4-oxadiazol-2-yl)biphenyl shows good spectral matching with the absorption spectra of the MLCT1 and MLCT3 transitions of Ir(ppy)3. The red-shift of the 0-0 band in the phosphorescence at 77 K is due to the intramolecular pi-pi interactions between the oxadiazole side chains. Maximum brightness of 43,000 cd/m2 with an efficiency of 26...
