Welcome! Using Moodle to Ease New Chemistry Students' Transition to Higher Education

The transition from high-school to university can be particularly daunting for students, especially if they are coming from abroad. We designed a Moodle page for incoming students with a view to helping alleviate their anxiety and reducing their cognitive load during induction week by introducing enrolment and departmental information early. The page was built by a first-year undergraduate, who used her own and her cohort’s experiences to design the content. Common questions were addressed, practice problems were provided and pre-reading and information about the department (including a virtual department tour and airline-style lab safety videos) was given. Students were automatically enrolled on the page as soon as they obtained their IT credentials in early September. They were asked to complete a quiz and questionnaires before induction week. The questionnaire gave insight into which features the students found the most useful, how confident they felt and what their expectations of university life were. The outcomes of the survey will be discussed and recommendations for similar pages will be made

Laparoscopic Closure of Acutely Perforated Duodenal-Ulcer - An Early Experience

Laparoscopic closure of an acutely perforated duodenal ulcer is an alternative procedure to open surgery. With proper training and experience this procedure might overtake laparotomy and simple closure thereby reducing the post operative morbidity in terms of reduced wound pain, short hospital stay, likely reduced wound sepsis and hernia occurrence and post operative chest complications. This article describes four patients with acute perforation of duodenal ulcer who were submitted to an emergency laparoscopic repair

High order quantum decoherence via multi-particle amplitude for boson system

In this paper we depict the high order quantum coherence of a boson system by using the multi-particle wave amplitude, whose norm square is just the high order correlation function. This multi-time amplitude can be shown to be a superposition of several "multi-particle paths". When the environment or a apparatus entangles with them to form a generalized "which-way" measurement for many particle system, the quantum decoherence happens in the high order case dynamically. An explicit illustration is also given with an intracavity system of two modes interacting with a moving mirror.Comment: 7 pages, revtex, 4 eps figure
