Plastic Oceans: A New Way in solving Our Plastic Pollution
<p>By 2050, the world’s oceans will have more plastic than fish with potentially catastrophic consequences on sea life and the health of the ocean. Economically, countries with coastal boundaries will be heavily impacted as plastic pollution has already generated a 13 billion dollars in monetary …

Plastic scintillation spectrometry
Plastic scintillators provide homeland security organisations with large area, low cost gamma-ray counters at international borders. Currently these detectors cannot distinguish between the sources they detect, leading to high false alarm rates during primary screening. These alarms must be …

A study of drug-plastic interactions in a variety of plastic containers
<p>In most hospitals today, plastic devices are replacing the traditional metal, glass and rubber. The increased use of polymeric materials as implanted prosthetic devices, catheters, disposable equipment and for the administration of blood, intravenous fluids and drugs has been widely accepted by …

The Effects Of Non-Plastic and Plastic Fines On The Liquefaction Of Sandy Soils
… be drawn as to how altering fines content and plasticity actually affects the liquefaction resistance of a sand. In fact, the literature contains what appears to be contradictory evidence. There is a need to clarify the effects of fines content and plasticity on the liquefaction resistance of …

COMPOSITIONAL EXPLORATIONS OF PLASTIC SOUND
… to explore a different aspect of music as a plastic art. Conclusions reached in the review of each new work were used to guide the development of the next. The notions of plasticity in sound, and sound as a plastic material were used to give the overall research a focal point. In exploring …

Plastic deformation of gallium arsenide
… to determine the validity of Haasen's model of plastic deformation for GaAs over an extended range of temperatures and to observe the relation between the dislocation density in the deformed samples and the deformation variables. The experimental results show a discrepancy with the predictions …

Innovative Plastic Optical Fiber Sensors
… frequencies. The developed sensors are based on plastic optical fibers instead of the traditional glass fibers, which are traditionally employed in optical communications. This change is related to the aim of realizing sensors maintaining the excellent typical characteristics of the fibers, such …

Plastic city and other stories
Plastic City and Other Stories is a set of inter-connected short stories that capture moments in the lives of members of one family. The stories traverse more than five decades of the family's years lived in Cape Town, South Africa. While the stories are essentially about the individual, greater …

A conjugated polymer plastic gel
… reversible physical crosslinks incorporate plasticity in the conjugated polymer gel. The gel network can be melted and then transformed via mechanical deformation to form an anisotropic gel with the chains highly aligned along the tensile direction. The oriented gel morphology comprises a …

A Local Solution to Plastic Pollution
Plastic pollution is a well-known issue across the globe with staggering facts such as: “Only 9% of all plastic produced has been recycled,” and “The Great Pacific Garbage Patch is a floating island of plastic waste spanning an area that is over twice the size of the state of Texas.” Locally, this …

All This Plastic, All This Glass
… for readers of all backgrounds. <em>All This Plastic, All This Glass</em> aims to begin a conversation about our anxieties, our fears, our bodies, and even death in a way that will allow us to connect to one another.</p>

Plastic Deformation in Complex Crystal Structures
… toughness is desirable. In complex crystals plasticity, and hence toughness, is limited by the energy increases that occur as linear defects, dislocations, move. This is known as the lattice resistance. By understanding the factors controlling the lattice resistance in complex crystal …
