Dowels are used in jointed concrete pavements to provide load transfer and improve performance. Misaligned dowels could cause poor joint performance that would lead to pavement distresses. An approach to detect misaligned dowel bars in concrete pavements using GPR is proposed. The paper addresses all forms and combinations of dowel misalignment. Equations were developed to identify each misalignment type, and statistical analyses were performed on major categories for the entire project. A decision on the acceptance or rejection of a dowel bar, a joint, or a pavement section, can be made based on the results of the computations and specified tolerance values. © 2014 Elsevier Ltd.

A hot-melt pressure-sensitive adhesive (PSA) was generated containing a high content of renewable biomass. The polymer is based on a commercial hot-melt acrylic formulation containing primarily 2-ethylhexyl acrylate (EHA). The new polymer is synthesized with a majority of the EHA replaced with a macromonomer (MM) prepared with l-lactide and μ-caprolactone via catalyzed bulk ring-opening polymerization using N-hydroxyethyl acrylamide as the initiator. Incorporation of the MM into the polymers was confirmed via proton NMR. The properties and adhesive performance of the new polymer were compared with those of its 100% acrylic commercial version. When synthesized using the same approach, the biomass-containing PSA had a lower molecular weight, higher glass transition temperature, and lower melt viscosity. Introduction of MM had little impact on the tack force, shear time, and shear adhesion failure temperature, and the peel strength increased substantially. It is expected that these hybrid materials can be optimized for a variety of self-adhesive applications. © 2014 American Chemical Society.

Insulated Concrete Form (ICF) walls are widely used for a full range of building designs including residential, theaters, schools, and hospitals. ICF manufacturers cite several advantages compared to traditional building materials but builders are concerned by honeycombing that may occur during the pouring of the concrete, where gaps are left in the concrete. The development of gaps generally occurs between the foam and the surface of the concrete. Acoustic sounding, a traditional inspection technique to locate voids, would be unsuccessful due to the plastic foam. In this research study, Ground Penetrating Radar (GPR) was proved successful in detecting gaps that developed between the foam and the concrete, voids intentionally created in the concrete, and voids that developed during the pouring operation. Small voids (e.g., less than in.) were difficult to detect but are not likely to cause any hazard to the structural integrity of buildings. The tests were performed at different stages of concrete curing using both the 1500 MHz and the 2600 MHz antennas. It is shown in this paper that the first void in the concrete was detected at day 7. However the best results were achieved at day 28 of curing. Data analysis has shown the success of the 1500 MHz antenna, but also the limits of the 2600 MHz antenna in the detection of buried voids in ICF structures. © 2011 Elsevier Ltd. All rights reserved.

We're changing... after a decade of bringing bikers together in London, shooting the best photo galleries, covering the latest motorcycling news and features, we had to take stock and ask ourselves if our course was right and if we could do things better and the answer is yes of course, who can't do better? The world has moved on and we need to too. The web is more open, content is shared further, everything's integrated and biking is getting higher tech too. Nearly everyone runs a helmet cam it seems, uses intercoms, has GPS and has a super-computer in their pocket. We've decided to reboot LB, cut it back to basics whilst we build a new LB to make it even more relevant to todays bikers. With that in mind, we're taking LB back to it's heart - a communication platform for bikers, starting from the forum and building, shaping new ways to bring london bikers together. So for now that means that some content such as news, features and galleries aren't available, but we'll bring them back. Perhaps not as they were but it would be a crying shame to lose more than ten years worth of content just because we're taking a new heading, so for now, please stick with us and we'll try not to let you down.

U.S. President-elect Donald Trump waves after arriving at John Glenn Columbus International Airport in Columbus, Ohio, U.S., December 8, 2016. REUTERS/Shannon Stapleton WASHINGTON (Reuters) - President-elect Donald Trump is receiving an average of one presidential intelligence briefing a week, according to U.S. officials familiar with the matter, far fewer than most of his recent predecessors. Although they are not required to, presidents-elect have in the past generally welcomed the opportunity to receive the President's Daily Brief (PDB), the most highly classified and closely held document in the government, on a regular basis. It was not immediately clear why Trump has decided not to receive the intelligence briefings available to President Barack Obama more frequently, or whether that has made any difference in his presidential preparations. Trump's spokespeople did not immediately respond to requests for comment. Trump has asked for at least one briefing, and possibly more, from intelligence agencies on specific subjects, one of the officials said. The source declined to identify what subjects interested the president-elect, but said that so far they have not included Russia or France. Indiana Governor Mike Pence, Trump's vice president-elect, has been receiving his own PDB at least six days a week, the sources familiar with the matter said. Former Central Intelligence Agency briefer David Priess, the author of a book about PDBs, said that traditionally, Trump and Pence's predecessors sat for "daily or near-daily intelligence briefings" between their elections and their inaugurations. He said Jimmy Carter and Ronald Reagan did not start receiving their daily briefings until later in November, while the delayed election result in 2000 meant that George W. Bush did not start receiving his until December. = The briefings are not compulsory. Priess said that after his first election, Richard Nixon spurned face-to-face briefings, so paper PDBs were delivered to his office, only for a "stack" of them to be later returned to the CIA, unopened. Trump's casual attitude to the briefings attracted criticism from Representative Adam Schiff, the top Democrat on the House Intelligence Committee. "It is deeply disturbing that the president-elect has time for rallies but not for regular intelligence briefings," Schiff said. During the run-up to the Nov. 8 presidential election, Trump and a handful of advisers received at least two briefings from intelligence officials about broad national security issues. However, the pre-election briefings did not include the kind of secrets that are included in the PDBs that Obama, Trump and Pence now have access to. Such secrets include information about U.S. espionage sources and covert operations overseas. PDBs are presented to presidents and their closest aides by representatives of the Office of the Director of National Intelligence (ODNI), though material in them is prepared by the CIA, the National Security Agency, the Defense Intelligence Agency and other parts of the U.S. intelligence community, the officials said. During and after the election campaign, Trump raised questions about the intelligence on hacking of U.S. political institutions. In a statement on Oct. 7, ODNI and the Department of Homeland Security expressed confidence that the Russian government had "directed" hacking into "emails from U.S. persons and institutions" that was "intended to interfere with the U.S. election process." Trump, however, has repeatedly dismissed suggestions that Russia was behind the efforts, telling Time magazine earlier this week: "I don't believe they interfered ... It could be Russia. It could be China. And it could be some guy in his home in New Jersey."
