We use the interaction between nulling and subpulse drift to determine the alias order of this drift in PSR B0809+74. We find that the subpulse drift is not aliased but directly reflects the actual motion of the subbeams. The carousel-rotation time must then be over 200 seconds, which is much longer than theoretically

The conserved phosphatidylserine receptor (PSR) was first identified as a receptor for phosphatidylserine, an 'eat-me' signal exposed by apoptotic cells. However, several studies suggest that PSR may also act as an arginine demethylase, a lysyl hydroxylase, or an RNA-binding protein through its N-terminal JmjC domain. How PSR might execute drastically different biochemical activities, and wheth...

OBJECTIVE The study was based at a South African hospital providing inpatient care for people with chronic mental disorders, and aimed at investigating the multidisciplinary team (MDT) members' views, understanding and attitudes towards psychosocial rehabilitation (PSR). METHOD A survey method was used, with the MDT members completing a questionnaire that tapped, inter alia, their understandi...

B chromosomes are centric chromosomal fragments present in thousands of eukaryotic genomes. Because most B chromosomes are non-essential, they can be lost without consequence. In order to persist, however, some B chromosomes can impose strong forms of intra-genomic conflict. An extreme case is the paternal sex ratio (PSR) B chromosome in the jewel wasp Nasonia vitripennis. Transmitted solely vi...

Periodontal Screening and Recording trade mark (PSR) is a diagnostic screening tool for the early detection of periodontal disease. The purposes of this study are to utilize PSR to estimate the periodontal health status of a representative military population and to compare the results with other studies of varying populations. When used to evaluate the periodontal health of a randomly-selected...

During its life, BeppoSAX observed several isolated pulsars, giving important contributions to the knowledge of the phenomenology and properties of the X-ray emission from this class of sources. In this paper I review the spectral and timing results obtained from BeppoSAX observations. In particular, results on three Crab-like (Crab, PSR B1509-58 and PSR B0540-69) and 3 millisecond pulsars (PSR...

This study investigated the role of dissolved organic matter on mercury partitioning between a hydrophobic surface (polyethylene, PE) and a reduced sulfur-rich surface (polysulfide rubber, PSR). Comparative sorption studies employed polyethylene and polyethylene coated with PSR for reactions with DOM-bound mercuric ions. These studies revealed that PSR enhanced the Hg-DOM removal from water whe...

We report the direct measurement of orbital period decay in the double neutron star pulsar system PSR B2127+11C in the globular cluster M15 at the rate of (−3.95± 0.13)× 10, consistent with the prediction of general relativity at the ∼ 3% level. We find the pulsar mass to be mp = (1.358 ± 0.010)M⊙ and the companion mass mc = (1.354 ± 0.010)M⊙. We also report long-term pulse timing results for t...

Observations have been made with the University of Durham Mark 6 telescope of a number of supernova remnants and young pulsars (Vela pulsar, PSR B1055–52, PSR J1105–6107, PSR J0537–6910 and PSR B0540–69). No VHE gamma ray emission, either steady or pulsed, has been detected from these objects.

Psychosocial/Psychiatric Rehabilitation (PSR) facilitates recovery of people with serious mental illness (SMI). Yet there is not much research on how to provide effective PSR education and training. We address PSR education and training in two relevant professions – psychiatry and occupational therapy. Further study of PSR education and training is needed.
