Abstract:

For many decades, fiber reinforced polymers (FRPs) have been extensively utilized in load-bearing structures. Their formability and superior in-plane mechanical properties have made them a viable replacement for conventional structural materials. A major drawback to FRPs is their weak interlaminar properties (e.g., interlaminar fracture toughness). The need for lightweight multifunctional structures has become vital for many applications and hence alleviating the out-of-plane mechanical (i.e., quasi-static, vibration, and impact) and electrical properties of FRPs while retaining minimal weigh

Abstract:

This thesis presents a computationally efficient software system to determine the minimum safety distances for human exposure to radio frequency radiation from wire antenna systems. Based on classical analytical methods and original code, a system was developed to calculate the occupational and general public safety zones from electromagnetic radiation emanating from wire antenna systems, according to maximum human exposure limits set by radio frequency communication standards. Isolated dipole and multi-element, Yagi-Uda style wire antenna arrays were considered in free space, as well as anten

The thesis deals with the problems of the photobiological lamp and lamps systems safety. It is divided into theoretical and practical parts. The theoretical part touches the basic knowledge concerning the eye and vision, eye and skin diseases caused by excessive exposure to non-ionizing radiation. And besides that there are described the sources of light causing the possible exposure and further more it includes the methodology of measurement and evaluation of photobiological safety. The practical part investigates a measurement of the spectrum of light sources. The measured data are evaluated

Possible health hazards have been investigated in a mineral sand processing plant to determine the risks to workers contributed by four principal sources: (i) External gamma radiation ii) Inhaled radioactivity in airborne dust particles (iii) Inhaled activity from airborne radon and radon daughter isotopes (iv) Respirable free silica Gamma radiation surveys of the plant working environs using a portable survey meter indicated possible exposure rates ranging from 70 nSv h-1 to a maximum of 50 μsv h- 1 (near a large pile of monazite sand). The average exposure rate was 400 nSv h-1 • Assuming

Abstract:

Outbreaks of food-born illness associated with the consumption of unpasteurized juice and apple cider have resulted in a rule published by the U.S. Food and Drug Administration (FDA) in order to improve the safety of juice products. The rule (21 CFR120) requires manufacturers of juice products to develop a Hazard Analysis and Critical Control Point (HACCP) plan and to achieve a 5-log reduction in the number of the most resistant pathogens. Ultraviolet (UV) disinfection is one of the promising methods to reach this 5-log reduction of pathogens. The absorption coefficients of juices typically va

This thesis contains reviews and research on the occupational hazards of zoo veterinary practitioners in Australia. Although occupational hazards have long been recognised in the veterinary profession, little information is available on the number and magnitude of injuries to veterinarians in Australia, the United Kingdom or the United States. Apart from anecdotal accounts and some limited data, most of the available information is on occupational zoonoses, generally well recognized by veterinarians. Other occupational hazards to which veterinarians are exposed have received scant attention. T

If the proportionality assumption holds, HR can be validly with the popular Cox proportional hazards model.

The nonlinear radiofrequency energy conversion can be detected by exciting the fundamental operating frequency and observing the second harmonic resonant frequency within a doubly resonant cavity. By implementing the proposed mathematical model, the required input power can be estimated to maximise the chance of detecting the weak second harmonic signal prior to carry out the measurement.
