Effect of anatomical fractionation on the enzymatic hydrolysis of acid and alkaline pretreated corn stover.

Due to concerns with biomass collection systems and soil sustainability there are opportunities to investigate the optimal plant fractions to collect for conversion. An ideal feedstock would require a low severity pretreatment to release a maximum amount of sugar during enzymatic hydrolysis. Corn stover fractions were separated manually and analyzed for glucan, xylan, acid soluble lignin, acid insoluble lignin, and ash composition.

Video-based computer-assisted learning.

As a relevant exemplar of MPEG-1 and MPEG-2 digital video use, a multimedia computer-assisted learning (CAL) application dealing with Critical Communication Issues in medicine was developed. The application allowed the student to navigate through a series of high-quality digital video and audio clips that were delivered in near real-time from an Intranet server. This paper gives a brief background to the MPEG-2 video compression system and discusses the use of digital video in a CAL environment.

Development and integration of CAL: a case study in medicine.

Context: The Faculty of Medicine and Medical Sciences at the University of Aberdeen viewed the use of Computer Assisted Leaning (CAL) and other IT based learning resources as a possible way of coping with an increase in student numbers whilst maintaining or increasing the quality of medical teaching.

Objectives: Our primary objective was to develop and integrate Computer Assisted Learning (CAL) applications into the undergraduate medical curriculum.

Subjects/materials: A wide spectrum of CAL applications were developed dealing with many topics in the curriculum.
