Development Of Iowa Dot Combination Bridge Separation Barrier With Bicycle Railing, Chaz M. Ginger
Development Of Iowa Dot Combination Bridge Separation Barrier With Bicycle Railing, Chaz M. Ginger
Department of Engineering Mechanics: Dissertations, Theses, and Student Research
The Iowa Department of Transportation typically builds separation barriers between vehicle and pedestrian/bicycle facilities when sidewalks or trails are present on vehicular bridges. Currently, Iowa DOT employs a combination bridge rail that utilizes a concrete parapet that previously had been successfully evaluated to National Cooperative Highway Research Program (NCHRP) Report 350 Test Level 4 (TL-4) criteria for these situations. While the parapet had been successfully evaluated, the combination bridge rail system as a whole had not been evaluated to any crash test standards. Iowa DOT desired that researchers at Midwest Roadside Safety Facility (MwRSF) design and test a combination bridge …

Modulated electro-hyperthermia (mEHT) is a form of hyperthermia used in the treatment of cancer. It is a variation that relies on a particular form of enhanced selectivity to enable more effective cancerous cell death yet maintaining the integrity of healthy non-cancerous cells. It is yet to successfully make the major step into the wider medical community despite several encouraging trials. In this study, we investigate mEHT from an in vitro perspective. We demonstrate a supra-additive effect on 9 L gliosarcoma cells when exposed to mEHT in combination with MV X-ray radiation. The supra-additive effect is hypothesized to be induced by …
Radiosensitisation Enhancement Effect Of Brudr And Ta2o5 Nsps In Combination With 5-Fluorouracil Antimetabolite In Kilovoltage And Megavoltage Radiation, Marjorie Mcdonald, Sianne Oktaria, Konstantin K. Konstantinov, Anatoly B. Rosenfeld, Michael L. F Lerch, Stephanie Corde, Moeava Tehei
Radiosensitisation Enhancement Effect Of Brudr And Ta2o5 Nsps In Combination With 5-Fluorouracil Antimetabolite In Kilovoltage And Megavoltage Radiation, Marjorie Mcdonald, Sianne Oktaria, Konstantin K. Konstantinov, Anatoly B. Rosenfeld, Michael L. F Lerch, Stephanie Corde, Moeava Tehei

This article demonstrates in vitro a synergistic effect on 9L gliosarcoma cells when exposed to bromodeoxyuridine (BrUdR) and a low concentration (100 times lower than the IC50) of 5-Fluorouracil (5-FU), in combination with x-ray irradiation. The synergy is brought about by several important factors including the x-ray beam energy, atomic number of the BrUdR (Z = 35), effectiveness of 5-FU in reducing the available repair processes and distribution of the BrUdR in and around the 9L cells (32% of the total substitution of BrUdR for thymidine into nucleus DNA). Our results show that the synergistic effect, evident in an optimised …
