Description

Presents results of a research project to create a cost-effective computing method to enable Time-Cost Trade-off (TCT) optimization analysis on construction projects of practical size and complexity reflecting those in the real world. The researchers aim was to work toward formalizing guidelines for TCT optimization that would consider safety and time and cost constraints related to the expedition of construction projects. It is postulated that having guidelines and analysis tools such as these may decrease hazardous situations and safety risks that have been associated with expedition of construction project schedules.

Description

Barrett's esophagus is a benign condition, usually caused by long-term gastroesophageal reflux disease. In some individuals the abnormal Barrett's tissue develops precancerous cells. Barrett's esophagus with high grade dysplasia is associated with a higher risk of developing one type of esophageal cancer. Interventions to remove the dysplastic tissue are intended to reduce this risk. Photodynamic therapy is one of several less invasive, endoscopic treatment options for Barrett’s esophagus that offer an alternative to surgical removal of the esophagus. This review assesses the evidence on the safety and effectiveness of photodynamic therapy for the treatment of Barrett's esophagus with high grade dysplasia in comparison to esophagectomy and other endoscopic treatments for this condition. It also examines the social and economic considerations for the provision of PDT in comparison to alternate treatments.

Description

This document presents ecologically based, reference-age invariant polymorphic height growth and site index models for major Alberta tree species. The models were developed using tree sectioning data from dominant and codominant trees. They can be used to predict the following: 1. Tree height from site index and breast height age, 2. site index from tree height and breast height age, 3. years needed for a tree to grow to a specified height, 4. height growth intercept. Since the models were fitted for the province as a whole and for groups of newly classified Natural Regions of Alberta, they can also be used to examine the regional differences of the height growth pattern. Relationships among breast height age, stump age and total age were also established so that compatible height growth and site index predictions can be made from any type of tree age. Tables and computer programs for predicting height growth and site index were prepared, along with a brief description of how to use...

Description

Research has shown that in Alberta, the amount of phosphorus in streams increases with agricultural intensity in watersheds. The goal of the Alberta Phosphorus Watershed Project was to determine if wide-spread adoption of environmental beneficial management practices would improve water quality at the watershed scale, as well as to develop the Alberta Phosphorus Management Tool. This report supplements the previously published 2013–2017 Alberta Phosphorus Watershed Project progress report by summarizing the results and progress of the Alberta Phosphorus Watershed Project from 2018–2020.

This article examines the impact of urban development on archaeological deposits within, and adjacent to, the North Saskatchewan River valley in the city of Edmonton in central Alberta. Recent... More ≫

Description

This article examines the impact of urban development on archaeological deposits within, and adjacent to, the North Saskatchewan River valley in the city of Edmonton in central Alberta. Recent archaeological studies indicate that undisturbed sediments are present and can yield significant archaeological deposits of both precontact and fur trade age, despite decades of extensive urban development.

Description

This study updated/developed flood damage curves in select communities at risk of flooding to 2014 economic values and established adjustment indices for their use in different flood prone communities across Alberta. It also developed a computerized model for estimating flood damages and undertook flood damage estimates for select communities throughout Alberta.

Description

Gillett's Checkerspot is a colourful and distinctive butterfly that has a very small global range and a global conservation status rank of imperiled/vulnerable. The species is relatively well known with respect to its biology and ecology. Available information is summarized in this report and differences between USA and Alberta populations are discussed. The ecology of the species renders it amenable to integration with economic activity. It can be accommodated without significant expense or impact on other natural resource uses. In some cases, forest canopy removal associated with development can be a positive factor for the species but in the past this has been an accidental byproduct of such activity. Brief strategic and operations guidelines are recommended.
