LeTourneau modified tank-tree crusher with R.G. LeTourneau and unidentified man.
Photograph of a Tree Crusher Tender built in Vicksburg, Mississippi and intended for use at the Tournata complex in Liberia, according to author Eric Orlemann. Shown with the tank are R.G. LeTourneau, left, and an unidentified man. The tank was never actually shipped to Tournata
Longview manufacturing plant under construction, LT21 Misc Photos Archive 062.
Photograph of the Longview manufacturing plant of R.G. LeTourneau, Inc. The plant's construction began in 1945 and completed in 1946. At the time, according to Otis Hays, author of R.G. LeTourneau: Move of Men and Mountains, at the time it was the world's largest welding and manufacturing plant under one roof, covering more than 100 acres
The Big Plow with 6-Foot Disc, J5G, Photo 35, L-8312
Photograph of R.G. LeTourneau's Series H (Model 6-16) Disc Plow, designed for land-clearing operations. It was powered by a front longitudinally mounted diesel, according to author Eric Orlemann
Large LeTourneau tree crusher, LT20
Photograph of aLeTourneau tree crusher with three unidentified men. This is likely the Series G-50 Tree Crusher, judging from a similar photo in author Eric Orlemann's book on R.G. LeTourneau's earthmoving equipment
The Added Value of Enterprise Architecture
Applying architecture implies that it provides added value across an enterprise. Although widely adopted, this claim has only been scarcely investigated, not to mention quantified. This document describes the results of a case study to quantify the effects of applying Enterprise Architecture within a financial institution called FinCom. For confidential information reasons, the name of this company is fictive. The thesis attempts to capture several factors at project level with respect to the application of Enterprise Architecture and its subsequent financial benefits. The study analyzed 40 projects, with regard to time and budget overrun. In order to collect these data, a total of 35 business, enterprise and domain architects were interviewed on their experience with these projects. Among factors taken into account were architecture type, project compliance to architecture and experience of the architect. Consequently, these factors are recorded in hypotheses that relate to the budget and time figures of the project. These hypotheses are incorporated in the 'Architecture Effectiveness Model' and statistically tested with the acquired data. This led to more than 12.000 calculations to show the subsequent benefits of Enterprise Architecture.Information ArchitectureComputer ScienceElectrical Engineering, Mathematics and Computer Scienc

The influence of the severity of community-acquired pneumonia on the usefulness of blood cultures
AbstractThe value of blood cultures in community-acquired pneumonia (CAP) has been questioned. At issue is the potential for blood cultures to change management. We prospectively studied the yield and impact of blood cultures in patients admitted with CAP. Two hundred and nine subjects had at least two blood cultures prior to receiving antibiotics. The severity of CAP was graded using the Pneumonia Severity Index (PSI). Twenty-nine patients (13·9%) had a pathogen identified by blood culture. The yield of blood cultures increased with PSI grade (I—5·3%, II—10·2%, III—10·3%, IV—16·1%, V—26·7%), as did the likelihood of blood cultures changing antibiotic therapy (I to III 0%, IV—9·7%, V—20·0%). One hundred and seventy-nine (85·6%) patients received a quinolone, limiting the impact of pathogens resistant to β -lactams. Four of 16 patients (25·0%) with a culture (blood or sputum)-guided change in antibiotic therapy died, compared to five of 31 patients (16·1%) who had an empiric change. Blood cultures are of minimal value in mild to moderate CAP, and should be limited to patients with PSI grade IV or V CAP unless a specific risk factor for pathogens resistant to the empiric therapy is present
