    The church was built in 1917 of concrete masonry blocks that were reportedly cast on site by members of the church. The main problem with the church exterior is the delamination of the exterior skin of the concrete block.

    7/22/2014 · Construction
    Constructed in 1934, the "Old Senior Hall" building was built with a structural steel frame, concrete and gypsteel floors and roof, and a reinforced concrete foundation. The exterior walls were built using a brick masonry façade over a clay tile backup with limestone sills, coping, and accents. Active corrosion of main structural members was discovered in the late 1990's, and a plan was developed to renovate the building to address structural concerns. Atkinson - Noland conducted a full exterior condition survey, including use of nondestructive tests to identify the extent of steel corrosion, evaluate masonry performance, and identify potential repair items. Results of this study were used to plan repairs and any necessary strengthening.

    6/10/2014 · Engineering
    The Health Center building on the Milton Hershey School campus was designed in 1932 as load-bearing masonry construction with steel framing used to support floor and roof loads and loose steel lintels spanning over window and door openings. Atkinson-Noland & Associates was retained to conduct an investigation of the exterior load-bearing masonry walls and structural steel framing for the purpose of identifying typical as-built conditions as well as the locations and severity of any deterioration.

    The 16th Street Mall in downtown Denver, Colorado is a pedestrian and transit mall that extends for more than a mile along 16th Street connecting people to major businesses, hotels, restaurants, and retail.

Atkinson-Noland & Associates conducted an extensive investigation at the 16th Street Mall granite tile pavers to determine the causes of distress in the paving system. We also helped develop appropriate solutions to paver debonding, slip-resistance, aesthetics, and maintenance.

    4/4/2014 · Construction
    Atkinson-Noland & Associates was a principal investigator on a three-year project evaluating different techniques for repair and retrofit of unreinforced masonry structures. Old masonry construction was simulated in the laboratory, and the test specimens were strengthened by installation of internal reinforcement or repaired by grout injection.

    2/26/2014 · Construction
    A six-story condominium building was constructed using load-bearing, concrete masonry with a clay brick masonry veneer. Specifications required that the collar joint be filled during construction; however, the contractor built the masonry without grouting the collar joint. Subsequent negotiation determined that the masonry must be reconstructed with a filled collar joint.

    Despite their history of successful use as fuel system disinfectants and fuel preservatives, antimicrobial pesticide use faces increasing restrictions due to both regulatory control and public concerns. A variety of non-chemical treatments have been used with varying degrees of success to disinfect non-fuel fluids and to at least partially inhibit biofilm development on infrastructure surfaces. Promoters of one technology have claimed successful fuel disinfection and fuel-tank fouling prevention. This paper will review a range of non-chemical treatment technologies and will present the results of preliminary evaluations of several technologies that were tested on Jet A fuels that had been challenged with either Pseudomonas aeruginosa or Hormoconis resinae. Data are presented on treatment impact on adenosine triphosphate (ATP) concentration, culturability and live/dead direct counts in Jet A-1 and on glass microcosm surfaces.

    4/29/2014 · Microbiology
    Several of the major points that I made in 1995 need further consideration, based on both changes in the regulatory climate and field experience with microbial contamination control in surface transportation markets.

    Smaller retailers depend on the expertise and reputations of their suppliers. Traditionally, refiners' attitudes about fuel were that if it met specifications at the time of sales, but failed later, the problem belonged to the owner at that time. As we begin to see impact of the Clean Air Act-driven fuel reformulations, increased consumer awareness and increased susceptibility to contamination, all market participants are going to have to cooperate to ensure that the customer with the engines gets consistently good fuel.

    2/20/2014 · Metallurgy
    Adenosine triphosphate (ATP) assays have been used to quantify bioburdens (biomass) in low-organic-compoundcontent fluids (freshwater, seawater, cooling tower water, and similar fluids) since the early 1950s. The original methodology was labor intensive and required considerable laboratory skill. Over the past half-century, the protocol has been simplified substantially, but until recently, chemical interferences made it impractical to use the ATP test in metalworking fluids (MWF).

    1/17/2014 · Microbiology
    Quantification of adenosine triphosphate (ATP) in fuels and fuel-associated waters was first presented at the Technische Akademie Esslingen 6th International Fuels Colloquium in 2007. At the time, two issues limited the overall usefulness of ATP as a test parameter: inability to differentiate between bacteria and fungi and inability to detect dormant microbes.

    12/11/2013 · Microbiology
    Three alternative, non-conventional test methods are evaluated for their ability to detect and quantify bioburdens in fuel and bottom-water samples. Two of the parameters, catalase activity and adenosine triphosphate (ATP) concentration have been used previously. This is the first report of the use of fluorescence polarization (FP) technology for fuel and fuel-associated water testing.

    11/6/2013 · Microbiology
    In August, 2012 a member of the LinkedIn Metalworking Fluids Group asked for a recommendation for the best biocide/fungicide package to be used to protect a semisynthetic metalworking fluid from biodeterioration. His posting has generated nearly 50 responses. Some of the suggestions were clearly based on limited experience; experience with few MWF, a limited number of MWF systems or both. I posted a number of comments to the string and have compiled them in this article.

    10/9/2013 · Microbiology
    Industrial lubricants are increasingly providing a rich environment for microbial growth and proliferation. Most of the knowledge of lubricant biodeterioration has been extrapolated from field and laboratory experience with metalworking fluids. Compositionally more complex than most lubricants, metalworking fluids are either solutions or emulsions of 5 to 10% coolant concentrate in water.

One area of attention that can payoff handsomely is the control of microbiological activity in coolant systems. Many engineers and plant operations personnel are just beginning to appreciate the effects on their machining operations caused by their plant "biosphere," which contains bacteria, fungus, mold and other contaminants.

    Mounting concerns over operational and waste management costs, as well as the quality and safety of the work environment have provided increased impetus for both formulators and end-users to strive to improve coolant life. There are a number of alterative approaches to achieving this objective. In this paper, the concepts of bioresistance and biostatic are defined and compared.

    All metalworking-fluid formulations share the common problem of susceptibility to microbial attack. This is not all bad news, since we need the used dilute fluid to be biodegradable for disposal purposes.

    6/19/2013 · Microbiology
    During the past decade we have witnessed a tumultuous debate over the disease risks posed by microbes that inhabit metalworking fluid (MWF) systems. Not infrequently, that debate has occurred in the absence of satisfactory data.

    Microbes in Fuel Retailing was the last in my series of NPN articles. In it, I presented a more global perspective on the key issues that I had addressed in earlier articles. Since 1999 there have been some watershed changes in the industry since it was written. The most important ones all involve dramatic changes in fuel product composition.

    Although the documentation of fuel biodeterioration dates back to the late 19th century, general recognition of the value of microbial contamination control evolved slowly until the 1980's. Since the early 1980's a number of factors have converged to stimulate greater interest in fuel and fuel system biodeterioration.

    Metalworking fluids provide an excellent environment for the growth and proliferation of a variety of bacteria and fungi. Historically, the incidence of infectious disease outbreaks at metalworking facilities has been rare. Consequently the primary focus of microbial contamination control efforts has been to prevent fluid biodeterioration.

    This is a personal injury case in which a car windshield was smashed and the driver injured by a tire that "came off" a truck that the car was following on a high-speed interstate highway. The car driver was hospitalized and the car towed. The truck had one of its rear tires replaced and then departed the scene of the accident.

    A London based arbitration process for breach of a contract to purchase tires brought by an International Earthmover Tire Manufacturer, plaintiff, against an International Mining Company, defendant. The Mining Company contractually agreed to order a specified number of tires or to pay 40% of the agreed selling price for any tires not ordered. This is referred to as a “Take or Pay” arrangement. The tire manufacturer contracted to produce tires that met the Tire and Rim Association OTR Handbook standards. The manufacturer did not guarantee tire performance, in terms of any performance measure.
