Summary form only given. Vision is the primary sense used in daily life. How do we "see" the world? Do we actually "see" it or rather "perceive" it? Or is it one and the same thing? How do people with optical eye defects perceive the world? Can normally sighted people partake in their experience? If you are blind or become blind, are you blind forever? On Earth and in the spaceflight environment, there are many effects and conditions that may impair your vision or lead to irreversible vision… 
Deploying the Mental Eye
Three observers performed a task designed to quantify their “pictorial relief” in visual awareness for a photograph of a piece of sculpture, finding that it is possible to direct the mental viewpoint actively.
Seeing the Meaning: Higher-Order Neuroplastic Changes in the Time Scale of Processing within Early Visual Areas in the Congenitally Blind
The function of blind striate and extrastriate cortices is a highly contested topic among researchers. Prior studies suggested that the occipital cortex in congenitally blind individuals can adopt
The effect of stereoscopic acquisition parameters on both distortion and comfort
This research is set out to provide a foundation for tolerance limits for comfort and perceptual distortions brought about by various virtual camera separations.

A Continuing Professional Development (CPD) module concerning residual blockade is published in this issue of the Journal, and it is shown that even if the use of pulse oximetry helped decrease the frequency of hypoxemic episodes, it does not influence patient outcome on major end points.
Complications Associated With Eye Blocks and Peripheral Nerve Blocks: An American Society of Anesthesiologists Closed Claims Analysis
Though most peripheral nerve block claims are associated with temporary injuries, local anesthetic toxicity is a major cause of death or brain damage in these claims.
“… Dreamt of, Indeed, but Utterly Unknown!”: The Earle Panoramas of the Tasman World
ABSTRACT In the early nineteenth century London society had the opportunity to view large panoramas of the Australasian settlements of Sydney (1828–30), Hobart Town (1831), and the Bay of Islands,
Disability and difference: Adolescents' interpretations based on television viewing
This study was conducted in order to decipher adolescent interpretations of disability that were portrayed on television. Employing qualitative methodology and methods, I conducted focus groups with
As one of the part of book categories, appearance always becomes the most wanted book, this means that many love to read this kind of book.
Mirror, mirror on the wall: the woman, the gaze and the fitness room
This study seeks to examine the gender forces at work in the sphere of athletics and aerobic sports in the Israeli context. This issue is of significance in the Israeli context in that women are
Claggett Wilson: The War Portfolio of 1919
Within months of the armistice that ended the First World War, the American artist Claggett Wilson (1887–1952), who had fought in France as a combat marine, produced a riveting portfolio of two dozen


Problems with forehead reflectance pulse oximetry.
A study of a " new " forehead reflectance pulse oximetry sensor in pediatric patients and found the bias and precision of the forehead sensor to be comparable to those of the finger sensor, and concluded that the Max-Fast provided as accurate an estimation of S aO 2 as did a commonly used digit-based transmittance sensor.
Relationship between malpractice litigation and human errors.
In this investigation at a university hospital, cases involving legal action against anesthesia providers were compared to deviations from the standard of care by anesthesia providers that resulted in disabling patient injuries as judged by peer review to determine the relation between these two occurrences.
Predictors of Pulse Oximetry Data Failure
Computerized anesthesia records may provide insight into the true incidence of pulse oximetry data failures and factors that are associated with such failures, and physical status, type of surgery, and intraoperative variables were risk factors.
Forehead Pulse Oximetry: Headband Use Helps Alleviate False Low Readings Likely Related to Venous Pulsation Artifact
Application of up to 20 mmHg pressure on the forehead pulse oximetry sensor using an elastic tensioning headband significantly reduced reading errors and provided consistent performance when subjects were placed between supine and up to 15° head-down incline (Trendelenburg position).
Role of monitoring devices in prevention of anesthetic mishaps: a closed claims analysis.
Anesthesiologist-reviewers examined 1,175 anesthetic-related closed malpractice claims from 17 professional liability insurance companies to determine if the negative outcome was preventable by proper use of additional monitoring devices available at the time of the review, and if so, which devices could have been preventative.
Relation between negligent adverse events and the outcomes of medical-malpractice litigation.
The severity of the patient's disability, not the occurrence of an adverse event or an adverseevent due to negligence, was predictive of payment to the plaintiff among the malpractice claims studied.
Pharmacologic and Functional Characterization of Malignant Hyperthermia in the R163C RyR1 Knock-in Mouse
Heterozygous R163C mice represent a valid model for studying the mechanisms that cause the human malignant hyperthermia syndrome and a diminished inhibitory regulation by Mg2+.
Complications associated with anaesthesiaa — prospective survey in France
Mortality was lower following complications during anaesthesia than for those during the recovery period, and the rate of complications appeared to be dependent upon several risk factors: the patient’s age, thenumber of associated diseases, the preoperative status, whether the operation was an emergency and the duration of procedure.
Frequency and localization of mutations in the 106 exons of the RYR1 gene in 50 individuals with malignant hyperthermia
Clear evidence is provided that mutations in the RYR1 gene are the predominant cause of malignant hyperthermia.
Survey of Anesthesia-related Mortality in France
The anesthesia-related mortality rate in France seems to be reduced 10-fold in 1999, and concerns regarding aspiration of gastric contents and anemia associated with postoperative ischemic complications were the associated factors most often encountered.
