Escape and Rescue from Submerged Vehicles

By: Gerald Dworkin

Each year, there are approximately 1,500 incidents and 600 deaths occur involving vehicles that have gone off the road and plummeted into the water. Therefore, the public needs to plan for these types of emergencies by (A) rehearsing the steps necessary for a successful self-rescue from a vehicle in the water, and (B) having the rescue/escape tools readily available for use during this type of emergency situation.

Establishing Radiation Therapy Treatment Planning Effects Involving Implantable Pacemakers And Implantable Cardioverter-Defibrillators

By: Michael Gossman, MS, DABR, RSO, et al

Recent improvements to the functionality and stability of implantable pacemakers and cardioverter-defibrillators involve changes that include efficient battery power consumption and radiation hardened electrical circuits. Manufacturers have also pursued MRI-compatibility for these devices

Ethical Responsibilities of a Professional Engineer as an Expert Witness

By: Gerald Davis

A licensed professional engineer (P.E.) is required to adhere to a Code of Ethics for Engineers in all work he undertakes. However, there are some special criteria when employed as an expert witness.

Evaluating Bus Stops

By: Ned Einstein

The previous article in this series emphasized the importance of transportation professionals selecting bus stops instead of students or their parents doing so. Regardless, while plenty of tools are available to help, the critical tool for evaluating and approving safe bus stops is a live Earthling.

Evaluating the Psychological Impact of Burns

By: Dr. Jane K. McNaught

Physical traumas such as a serious burn injury can be profoundly traumatic. Serious burns result in sudden unanticipated trauma related to the individual's exposure to a potentially life-threatening experience. One day the burn victim begins their day like any other, and by the end of the day the burn victim's life may be changed forever by the traumatic event experienced. A Forensic Psychological Expert utilizes well respected psychological tests to assess the emotional impact of such injuries. The psychological tests employed are statistically reliable and valid. The choice of valid and reliable psychological tests employed by a Forensic Psychologist are similar to tests used by a physician to diagnose diabetes or other medical disorders. Such tests offer norms that compare the individual in question to a large normative sample, in order to evaluate the burn victim's psychological functioning compared to that of the "normal" person.

Evaluation of a Ventricular Assist Device: Stability in a Proton Beam Therapy

By: Michael Gossman

Inadequate research exists regarding testing of a ventricular assist device (VAD) for susceptibility to radiation damage. Specifically, minimal data are available to radiation oncologists prescribing treatment plans for patients with an implanted VAD. As the number of implanted devices increases, patients requiring radiation at tissue sites near or at the device will increase.

Evaluation of a Ventricular Assist Device: Stability Under X-Rays and Therapeutic Beam Attenuation

By: Michael Gossman

Improved outcomes and quality of life of heart failure patients have been reported with the use of left ventricular assist devices (LVADs).

Evaporator Leak Mitigation By Suction Control Valve Selection And Operation

By: James Caylor, PE

Evaporator leaks expose plant personnel to risk of ammonia contact and require maintenance intervention since refrigeration control valves used for inlet flows (liquid and hot gas) can automatically stop flow, but similar valves used for outlet flows (suction and refrigerant defrost condensate) cannot stop flow backwards from the suction line into a damaged evaporator and thus into the conditioned space.

Event Data Recorders and Collision Investigation

By: Al Duncan

Event Data Recorders (EDRs) were first introduced by General Motors (GM) in 1974. That data was only available to GM; however, since 1994 more and more vehicle EDR’s have recorded data that can be gathered. The data captured can be imaged and is being used by vehicle manufacturers, law enforcement officers, and collision reconstructionists to better understand what is happening in a collision. In accident investigation, EDRs have the potential to provide independent measurements of crash data that would elsewise be estimated by reconstruction methodology.

Excise Taxes For Unreasonable Compensation At Charities

By: Stephen D. Kirkland, CPA, CMC

The Internal Revenue Service (IRS) now keeps a close eye on charities and social welfare organizations to ensure that their tax-exempt status is not abused. One of the primary factors the IRS now examines is the amounts of compensation and benefits provided by charities to their key employees
