background:  clavicle fractures are common and usually heal without complications. in this study, we evaluated the outcomes of non-operative versus operative management of displaced fractures.   methods:  in a prospective clinical trial study, sixty-five patients with displaced clavicle mid-shaft fractures were nonrandomly divided in two treatment groups. the first group underwent non-operative...

Within both game studies and development communities, it is often argued that a game’s processes (rules and goals) are of primary significance when considering a game’s meaning. In opposition to this position, some claim that this approach denies player subjectivity by ignoring the dynamic, culturally-embedded ways in which players create, rather than receive, meaning through play. This paper c...

Long term defence planning is a complex undertaking involving many separate analytical steps and with non-trivial transitions from one step to the next. Many nations struggle with the challenge of establishing analytical rigour, structure and traceability in their defence planning processes. In this paper we will present a tool that has been developed not only to support defence planning, but w...

The Central Computing services at the Universiteit van Amsterdam (UvA) [17] have deployed an instance of the JASIG Uportal [18] system for use by a student audience of around 22,000. To achieve the requirement of a homogenous experience for the end user required a transition to a more consistent and unified Single Sign-On (SSO) and Single Sign-Off interaction with the underlying diverse infrast...

we give further results for perron-frobenius theory on the numericalrange of real matrices and some other results generalized from nonnegative matricesto real matrices. we indicate two techniques for establishing the main theorem ofperron and frobenius on the numerical range. in the rst method, we use acorresponding version of wielandt's lemma. the second technique involves graphtheory.

the postgastrectomy recurrence rate is as high as 30-65%, with 5-year overall survival rates of <20%. local recurrence is very common which occurs in 38-45% of cases. the most common sites of locoregional recurrence are the gastric remnant at the anastomosis, the gastric bed, and the regional nodes. the recurrence may occur as early and late events after gastrectomy. most recurrences are early,...

atrioventricular groove rupture is a rare, albeit mortal, complication following mitral valve surgery. avoidance is the best strategy but it cannot fully prevent the occurrence of this complication. several repair techniques have been described with varying success rates; however, the rarity of the complication precludes consensus about the safest technique. here we report two cases of posterio...

this trial was performed to determine if a continuous low-dose infusion of methylprednisolone is as effective as its bolus of high-dose in reducing inflammatory response. the study was single-center, double-blinded randomized clinical trial and performed in a surgical intensive care unit of an academic hospital. in this study, 72 consecutive patients undergoing elective coronary artery bypass g...
