The polyethylene industry has been in the midst of major restructuring and rationalization. This has lead to joint ventures and alliances to combine technologies and exploit opportunities to maximize improvements in process productivity, catalyst innovations, and enhancements in extrusion technology and converting.

This comprehensive study of the polyethylene film extrusion process describes this technology in detail. In depth descriptions of the manufacturing processes for polyethylene homopolymers and copolymers, including metallocenes, are reviewed. All aspects of machine design with particular emphasis on screws and dies including coextrusion are discussed comprehensively. With computer modeling, the interactions between equipment and polymer are quantified.

All aspects of equipment design and polymer features that control melt fracture, interfacial instabilities, gauge control, output and temperature, and cooling of blown and cast film processes are presented quantitatively. This methodology will highlight solutions in troubleshooting for optimum design and operation and the best available polymer and formulation choices.

All polyethylene film applications in packaging, agriculture, lamination, and construction, consumer, industrial, and health care are reviewed and discussed in depth.

In his book "Bulls-eye" - Journal of a Black Hawk pilot, Deeter takes his readers on a trip to the middle east, and gives them a first hand look at the life of an Army Helicopter Pilot in the war in Iraq. From the scorching temperatures to the grueling pace of combat, his journal entries paint an accurate picture for the reader of the day to day life of a Black Hawk pilot in the Iraq war. His story of his deployment to Iraq provides not only an up close look at the war, but also a view of the struggles deployed soldiers endure, both on the battlefield and upon returning home.

It has not seemed desirable to include many words that are rarely if at all used at present and which are in the older glossaries many words from fields closely related to ecology such as forestry, range management, agronomy, soils, and genetics are included because of their wide usage in ecological literature.The definitions are usually those that are in accord with present general usage. It has not seemed wise to attempt to pronounce judgment on the desira-bility of, or the need for, certain terms since decisions are made by usage as a language grows. The inclusion of certain words in this dictionary does not necessarily imply that the author approves or recommends their use.

Grace Abounding to the Chief of Sinners (1666) is a spiritual autobiography by English author and Puritan preacher John Bunyan. Written while Bunyan was serving a lengthy prison sentence for preaching without a license, Grace Abounding to the Chief of Sinners is both a record of Bunyan's personal experience, the story of his conversion, and a document of a time of historical and political crisis in England. The restoration of King Charles II to the throne in 1660-which followed years of sectarian violence and the 1649 execution of his father Charles I-initiated a period of religious and political repression. Nonconformist Christians, and preachers especially, were forbidden from practicing their faith, a crime for which Bunyan was arrested. He was tried and convicted in 1661, spending the next twelve years in Bedford County Gaol. Grace Abounding to the Chief of Sinners, written and published during this period, is the story of Bunyan's life, focusing on his conversion to Puritanism and his personal trials as a man punished for his beliefs. Containing numerous biblical references, Bunyan's work is similar to Saint Augustine's Confessions in its compositional structure-beginning with the author's sinful youth, it moves through his process of conversion to his growth as a Christian and rise to the status of preacher. Where it differs, however, is in its detailed description of Bunyan's arrest and imprisonment, a time he relied on his belief in God to carry him safely through. While less popular than The Pilgrim's Progress, a Christian allegory Bunyan began writing in jail, Grace Abounding to the Chief of Sinners is an important and powerful work which has inspired generations of Christians, including John Brown and Martin Luther King Jr. With a beautifully designed cover and professionally typeset manuscript, this edition of John Bunyan's Grace Abounding to the Chief of Sinners is a classic of English literature reimagined for modern readers.

"Steve Sailer gives us the real Barack Obama, who turns out to be very, very different - and much more interesting - than the bland healer/uniter image stitched together out of whole cloth this past six years by Obama's packager, David Axelrod. Making heavy use of Obama's own writings, which he admires for their literary artistry, Sailer gives the deepest insights I have yet seen into Obama's lifelong obsession with 'race and inheritance,' and rounds off his brilliant character portrait with speculations on how Obama's personality might play out in the Presidency." - John Derbyshire Author, Prime Obsession: Bernhard Riemann and the Greatest Unsolved Problem in Mathematics

For all that we think we're getting out of social media, we're also getting duped. The perfection echo chamber oftentimes makes us feel like we're getting left behind. The truth is, life is messy, but curated online fabulousness makes it hard to let our true selves show, and it impedes our ability to have real, meaningful connections.
