The process of icing involves the freezing of overflow layers, on ground or within streams, and results in ice bodies called “aufeis” that are common in most northern landscapes. Knowledge about aufeis is still limited despite the cold region engineering challenge they represent. Understanding the causes of overflow events leading to aufeis development represents a key for the prediction, mitigation, and management of this geohazard and can also support the planning and design of infrastructure in the North. This paper introduces a practical classification for the diverse range of overflow processes that generate aufeis, including under-represented processes, such as the instability of winter streamflow. Importantly, it distinguishes flow conveyance from water supply overflow processes and describes the temporal aspect of icing intensity. Finally, research topics are proposed to improve our understanding of aufeis, including their predictability, the impact of climate change on their occurrence and extent, and stream morphology–aufeis interaction.

ABSTRACTThis article examines the effects that present decisions about open access (OA) will have over the next ten years. It will be shown that the consequences are affected both by deliberate choices of policy by librarians and publishers, as well as by the adoption of various alternatives by scientific authors. The eventual result could be excellent, or quite otherwise.

Health care providers including nurses and childbirth educators are crucial resources for childbearing families for accurate and current information regarding nonpharmacologic and pharmacologic interventions available for pain management in labor. All medications that are administered to laboring women have maternal and fetal effects. In order to assist women in the decision for relief of labor discomforts, health care professionals must be knowledgeable of the chemical actions and adverse effects of all medications offered to women in labor. This article discusses various types of therapeutic options used for pain management for the relief of labor discomfort.

We report the use of serum prostate specific antigen (PSA) estimations prior to clinic attendance in 234 patients referred with symptoms of bladder outlet obstruction to a general urology clinic. Ninety-three patients with PSA levels > 10 ng/ml were seen earlier than planned and offered transurethral resection or transrectal biopsy of the prostate gland. Forty-six patients (49%) proved to have carcinoma of the prostate, compared with 10 of 141 (7%) patients who had PSA values < 10 ng/ml. With a decision value of 10 ng/ml, the sensitivity for detecting carcinoma was 82% and specificity 73.5%. Using a decision value of 7 ng/ml improved the sensitivity to 95% without significantly affecting the specificity (70%). Twenty-four patients with prostatic cancer had bone metastases; the sensitivity of PSA for predicting a positive bone scan using a decision value of 25 ng/ml was 92%, but the specificity was only 31%.

Adults with severe dyslexia were compared with age-, sex-, IQ- and SES-matched controls on a neuropsychological and neuromotor test battery, and a contrast group who had recovered from dyslexia was also included. The severely dyslexic group was substantially impaired on tests of verbal fluency and learning, as well as on non-verbal temporal order judgements. These test scores were strong predictors of the degree of reading impairment, as was the rate of repetitive movement of the right hand and foot. The results suggest that adult dyslexia is not 'isolated', but is one expression of a widespread left-hemisphere dysfunction.

The asymptotic form for the wave-function of a spin-1/2 particle scattered by a Coulomb potential is discussed. A convergence theorem is proved establishing the existence of a generalized Moller wave-matrix. Problems remaining in the theory are mentioned.
