We report on the analysis of archival ASCA, ROSAT and BeppoSAX data of PSR B1055−52, PSR B0656+14 and Geminga, performed in order to investigate the reality of the putative ∼ 10–20 arcmin wide X-ray pulsar-wind nebulae recently proposed to exist around these pulsars. In all these cases, the ROSAT and/or BeppoSAX data show that the diffuse and clumpy X-ray nebulae found by ASCA can be resolved i...

Abstract The singularity problem brings troubles to the design and application for parallel mechanism. Currently, redundant actuation is one of useful methods solve this problem. However, faced numerous joints in a mechanism, how make quantitative criterion seeking most efficient added actuators letting mechanism passes through necessarily open issue. This paper focuses on 2R1T 3-UPU (U univers...

ISSUE ADDRESSED The aim of this paper was to examine the eating behaviours, physical exercise and television viewing of secondary school students, and to investigate their relationship with parental monitoring and family cohesion. METHOD The study was conducted at a secondary school in Auckland, New Zealand, in 2005. Questionnaires were administered to 433 students aged 13-16 years, spanning ...

Fine particulate matter (PM₂.₅) has been associated in humans with inflammation, oxidative stress and cancer. Studies had shown that curcumin could potentially inhibit these effects; however, there had been no in vivo or in vitro reports about the effects of curcumin on organisms exposed to PM₂.₅. This predictive study explored the possible biological functions and pathways involved in the mech...

BACKGROUND The aim of this study was to analyze diurnal profiles of physical activity for community-dwelling adults aged 70 years and over, and to explore the moderating effect of sex, age, morbidity, mobility limitation, and season on physical activity throughout the day. METHODS A sample of 149 primary health care patients (mean age 79.5 ± 5.2 years, 74.5% females) was included in the analy...

s Caries Res 2009;43:179–244 187 with MH were prepared by sectioning and polishing. Cross-sectional Vickers hardness of the 600  m thick enamel sections was measured across MH-affected and apparently sound areas and mean hardness values analysed by one-way ANOVA. Subsequently these sections were lapped to 100 m and assessed using polarizing microscopy (PM) and transverse microradiography (TMR)...

The primary objective of this study was to evaluate the psychometric properties of the Psychological Maltreatment (PM) and Neglect subscales of the Computer Assisted Maltreatment Inventory (CAMI; DiLillo et al., 2010). The CAMI is a retrospective self-report measure that assesses multiple forms of child maltreatment (i.e., sexual, physical, psychological, neglect, exposure to interparental viol...

OBJECTIVE The effects of combined physical activity and hormone replacement therapy (HRT) on insulin sensitivity in postmenopausal (PM) women are unclear. The purpose of the study was to test the following hypotheses: 1) PM women who have undergone vigorous exercise training have greater insulin sensitivity than PM women who are physically active and PM women who are sedentary, and 2) PM women ...

Objective(s) Bupropion is an atypical antidepressant that is widely used in smoke cessation under FDA approval. The study of synaptic effects of bupropion can help to finding out its mechanism(s) for stopping nicotine dependence. In this study the effects of perinatal bupropion on the population spike (PS) amplitude of neonates were investigated. Materials and Methods Hippocampal slices were...
