High-Level IPM at Cooperstown’s Doubleday Field

Doubleday Field is a much loved, historic ballfield owned by the Village of Cooperstown, which has set a policy to try and eliminate pesticide use on Village property. The facility is subjected to intense traffic, hosting over 300 games this year, rain or shine, as well as community events. With the support of the NYS IPM Program, Doubleday Field was managed during the 2012 season using high-level IPM. Many of these practices continued under new management in 2013. While largely successful, weeds continue to be an issue and weed management needed to be revisited. In 2014, high-level IPM with the support and recommendations of the project team was continued, with an eye towards the compelling case study and educational opportunities to help garner support from players and educate the public about IPM. 2014 proved to be an undemanding year for turfgrass management, and strict adherence to the core cultural practices of mowing, fertilizing, irrigation, and overseeding provided a relatively pest free playing field. It was determined that no alternative pesticides were necessary to control weeds or insects in the field. Weeds in the warning track and under the bleachers continued to cause some issues, but the addition of warning track material and diligent manual raking and flaming kept these issues under threshold levels.

Transpapillary drainage has no added benefit on treatment outcomes in patients undergoing EUS-guided transmural drainage of pancreatic pseudocysts: a large multicenter study

Background and Aims The need for transpapillary drainage (TPD) in patients undergoing transmural drainage (TMD) of pancreatic fluid collections (PFCs) remains unclear. The aims of this study were to compare treatment outcomes between patients with pancreatic pseudocysts undergoing TMD versus combined (TMD and TPD) drainage (CD) and to identify predictors of symptomatic and radiologic resolution. Methods This is a retrospective review of 375 consecutive patients with PFCs who underwent EUS-guided TMD from 2008 to 2014 at 15 academic centers in the United States. Main outcome measures included TMD and CD technical success, treatment outcomes (symptomatic and radiologic resolution) at follow-up, and predictors of treatment outcomes on logistic regression. Results A total of 375 patients underwent EUS-guided TMD of PFCs, of which 174 were pseudocysts. TMD alone was performed in 95 (55%) and CD in 79 (45%) pseudocysts. Technical success was as follows: TMD, 92 (97%) versus CD, 35 (44%) (P = .0001). There was no difference in adverse events between the TMD (15%) and CD (14%) cohorts (P = .23). Median long-term (LT) follow-up after transmural stent removal was 324 days (interquartile range, 72-493 days) for TMD and 201 days (interquartile range, 150-493 days) (P = .37). There was no difference in LT symptomatic resolution (TMD, 69% vs CD, 62%; P = .61) or LT radiologic resolution (TMD, 71% vs CD, 67%; P = .79). TPD attempt was negatively associated with LT radiologic resolution of pseudocyst (odds ratio, 0.11; 95% confidence interval, 0.02-0.8; P = .03). Conclusions TPD has no benefit on treatment outcomes in patients undergoing EUS-guided TMD of pancreatic pseudocysts and negatively affects LT resolution of PFCs

Performance of FRP Strengthened Concrete Columns Under Simulated Blast Loading

In this thesis the effectiveness of CFRP laminates as externally applied column jacketing material was investigated experimentally. The research project forms part of a comprehensive research program with a scope of developing FRP protection systems for reinforced concrete columns subjected to extreme loads. The research program is carried out by a multi-disciplinary team including various institutes of the National Research Council Canada and the University of Ottawa. The experimental program of the current project consists of nine half-scale seismically designed reinforced concrete (RC) columns, tested under combined axial compression and simulated lateral blast loading, applied statically. Seven columns were strengthened by four types of CFRP laminates. The columns were first subjected to service axial loads of 45% of the design axial load capacity, followed by uniformly distributed lateral load up to failure. The columns were analyzed under incrementally increasing static loads, well into the inelastic range of deformations. The FRP was modelled as a linear material up to rupturing in tension. The behaviour of CFRP in compression was modelled with reduced strength and modulus of elasticity. It is found that the use CFRP laminates as column jacketing improves strength and deformability of the columns significantly. The use of CFRP laminate with unidirectional fibers and woven ±45° laminas results in significantly lower lateral deformation than companion unretrofitted columns. The retrofitted columns also develop well distributed strains within the critical plastic region, promoting a better redistribution of stresses. Adding woven ±45° laminas resulted in higher deformability and slightly lower strength than the laminate with only unidirectional fibers. The overall conclusion of the project is that the CFRP jackets, when designed properly, especially with the addition of ± 45 degree fibres result in significantly improved strength and deformability of concrete columns
