The derived category of a graded Gorenstein ring

We give an exposition and generalization of Orlov's theorem on graded Gorenstein rings. We show the theorem holds for non-negatively graded rings which are Gorenstein in an appropriate sense and whose degree zero component is an arbitrary non-commutative right noetherian ring of finite global dimension. A short treatment of some foundations for local cohomology and Grothendieck duality at this level of generality is given in order to prove the theorem. As an application we give an equivalence of the derived category of a commutative complete intersection with the homotopy category of graded matrix factorizations over a related ring.Comment: To appear in the MSRI publications volume "Commutative Algebra and Noncommutative Algebraic Geometry (II)

Serious Gordon: Using Serious Games to Teach Food Safety in the Kitchen.

This paper will describe the development of Serious Gordon, an interactive digital game developed to tech the basics of kitchen food safety to workers in industries dealing with food. The motivations driving the development of the game will be described as will the development process itself. An initial evaluation of the game, from both a technical and pedagogical point of view, will be presented as will conclusions on the viability of using a commercial game engine for the purpose of developing educational games

Magnetic Resonance Imaging in Cervical Facet Dislocation: A Third World Perspective

Study Design:Retrospective case series. Purpose: The objective of our study was to determine the change in management brought about by magnetic resonance imaging (MRI) of the cervical spine in alert and awake Patients with facet dislocation and spinal cord injury presenting within 4 hours after injury. Overview Of Literature: Spinal cord injury is a common clinical entity. The role of MRI is well established in evaluating spinal trauma. However, the time at which MRI should be used is still controversial. Methods: Retrospective data from 2002-2010 was evaluated. All of the alert and awake Patients with spinal cord injury, based on clinical examination with facet dislocation diagnosed on lateral cervical spine X-rays, were included. A questionnaire was also conducted, the data of which consisted of demographic details including age and sex, the mechanism of injury, clinical examination, X-ray findings, MRI findings, whether or not surgery was performed and the time elapsed since injury. Data was analyzed using SPSS ver. 17.0. Continuous variables such as age were expressed in terms of mean standard deviation. Categorical variables such as change in management, X-ray/MRI findings and neurological motor level were assessed in terms of percentage. Results: Fifty Patients participated in our study. All these Patients had spinal cord injury with defined motor levels. The mean age was 35.5 8.95 years (range, 20 to 52 years). Fifty percent showed a motor level at C6 level. None of the Patients required any change in management based on the MRI. Conclusions: MRI of the spine in awake Patients within 4 hours after injury does not change the management of Patients. However, we can hypothesize that such Patients can proceed to traction without waiting for the MRI
