Miniature blimps with chemical detection strips

This project involves the redesign of a commercially available miniature blimp in order to perform indoor detection of airborne hazardous chemicals. A 60-in. long blimp is retrofitted with two gondolas and modified to reduce weight and increase lift. One gondola houses the horizontal propulsion unit and the wireless camera. The second gondola houses the vertical thrust unit and deploys a chemical detection strip in view of the camera. The redesigned blimp allows for indoor real-time detection of hazardous chemicals

Opening a little theatre

Opening a Little Theatre was a voyage taken by the MQP team. Armed with designs, ideas, and a wonderful production staff, they were able to open two world premieres in one night in the Little Theatre, the first space at WPI dedicated to theatre arts. The team worked against incredible odds, including unfinished space, rain leaks destroying dimmer racks, and a defiant fog machine, to deliver a wonderful show at the precise moment demanded by the inflexible publication deadline

PIEE at Elm Park and Midland Street elementary schools

The PIEE Program, sponsored by the NSF, is dedicated to integrating engineering into school science programs. The IQP team worked with the Worcester Public School system to develop engineering lessons for five fourth-grade classrooms. According to the Massachusetts science and Technology Engineering Curriculum Frameworks and the Worcester Public Schools Benchmarks, the IQP team assisted the teachers with lesson implementation. To judge each lesson's effectiveness the IQP team developed a feedback rubric for the teacher's feedback

RRs for provision of bariatric surgery within adults eligible for bariatric surgery in England with at least 5 years of follow-up data in CPRD GOLD (2007–2020).^a (MODEL B).

BackgroundAdults living with overweight/obesity are eligible for publicly funded weight management (WM) programmes according to national guidance. People with the most severe and complex obesity are eligible for bariatric surgery. Primary care plays a key role in identifying overweight/obesity and referring to WM interventions. This study aimed to (1) describe the primary care population in England who (a) are referred for WM interventions and (b) undergo bariatric surgery and (2) determine the patient and GP practice characteristics associated with both.Methods and findingsAn observational cohort study was undertaken using routinely collected primary care data in England from the Clinical Practice Research Datalink linked with Hospital Episode Statistics. During the study period (January 2007 to June 2020), 1,811,587 adults met the inclusion criteria of a recording of overweight/obesity in primary care, of which 54.62% were female and 20.10% aged 45 to 54. Only 56,783 (3.13%) were referred to WM, and 3,701 (1.09% of those with severe and complex obesity) underwent bariatric surgery. Multivariable Poisson regression examined the associations of demographic, clinical, and regional characteristics on the likelihood of WM referral and bariatric surgery. Higher body mass index (BMI) and practice region had the strongest associations with both outcomes. People with BMI ≥40 kg/m2 were more than 6 times as likely to be referred for WM (10.05% of individuals) than BMI 25.0 to 29.9 kg/m2 (1.34%) (rate ratio (RR) 6.19, 95% confidence interval (CI) [5.99,6.40], p 2 with a comorbidity (0.53%) (RR 5.52, 95% CI [5.07,6.02], p p p p p p ConclusionsBetween 2007 and 2020, a very small percentage of the primary care population eligible for WM referral or bariatric surgery according to national guidance received either. Higher BMI and GP practice region had the strongest associations with both. Regional inequalities may reflect differences in commissioning and provision of WM services across the country. Multi-stakeholder qualitative research is ongoing to understand the barriers to accessing WM services and potential solutions. Together with population-wide prevention strategies, improved access to WM interventions is needed to reduce obesity levels.</div
