An Auspicious Beginning - A Favorable Setting A Propitious Forestry Summer Camp

The 1984 Forestry Camp was held at Camp Cassaway on the Chippewa National Forest in northcentral Minnesota

From Iowa to Montana and Back Again: Forestry Camp- 1987

The 1987 Forestry Camp was held from June 27 through August 5, 1987 at the Lubrecht Experimental Forest, Greenough, Montana. The late start was due to another group slated to use the Lubrecht for the first three weeks in June. ISU foresters have used this University of Montana facility several times over the 73 years of forestry camp. This year, as in past years the students and staff enjoyed the hospitality of the staff and natural resources professionals who helped with tours or field exercises. The success of the camp was due largely to three factors: 1) a great bunch of students eager to learn and willing to endure our high expectations, 2) exceptional support and aid from the Lubrecht staff of Mr. Hank Goetz, Manager, Mr. Frank Maas, Assistant Manager, and Dr. Robert (Bob) Pfister, Project Director of the Mission Oriented Research Project (MORP), and 3) a dedicated, enthusiastic staff consisting of Dr. Richard (Dick) Schultz, Dr. Monlin Kuo and myself

Forecasts of Wastepaper Supply and Consumption In The United States To 1985

Recycling of wastepaper is a partial solution to the solid waste management problem and a source of fibrous material in the production of paper and board products. Unlike virgin fiber, wastepaper is the result of past paper and board consumption. To consider these important facts and others affecting wastepaper supply and consumption, a model of the paper and board industry inclusive of wastepaper recycling was constructed. The results of application of this model showed that wastepaper supply and consumption can vary widely depending on the future recovery rates and utilization levels of wastepaper by the paper industry. By assuming the most optimistic wastepaper recovery and utilization increases by 1985, a domestic wastepaper supply shortfall is forecasted. However, the most likely future wastepaper utilization scenario indicates a surplus of wastepaper by 1985 given average recovery rates. The model can be used to consider a broad range of wastepaper recovery and utilization situations and alternative economic growth rates

Agroforestry- Growing Crops, Livestock, and Trees on Iowa Farms and the Midwest

Agroforestry is formally defined as a land-use system that intentionally combines trees or shrubs with annual plants and/or animals on the same land area. The combination may exist at the same time or in a sequential fashion (Agroforestry Systems, 1982). The production of diverse agronomic and forestry outputs (hence agro-forestry ) on the same land area is an important feature that may be very practical in trying to strengthen and diversify the primarily agricultural economy of Iowa. While agroforestry is still an emerging food, fiber, and industrial material production system in the American Midwest, it has been proven to be a sustainable system of land use in many parts of the world. Sustainability implies that this land use system is a healthy, economically viable, and environmentally protective technology

Computers in Forestry- A Modem Tool

Foresters, like other professionals, are using computers more and more frequently in their daily decision-making routine. Modern computers are lighter, more powerful and offer more tailor-made means to solve forestry-related problems than they did only a few years ago. When Drs. Atanasoff and Berry invented the first electronic digital computer here at Iowa State University in 1939, they probably had no idea of the sweeping impact this tool would have on mankind. For sure, they did not envision dirt foresters or timber beasts using computers to process inventory data, or project the growth and development of mixed hardwood stands, or determine the cutting budget for a one million acre National Forest for the next ten years or more

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic : an international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks
