A concrete reinforcement assembly including a first hollow metal sleeve, an anchor bar that is nested concentrically within the first hollow metal sleeve, and a second hollow metal sleeve. The first hollow metal sleeve is nested concentrically within the second hollow metal sleeve and an infill material is disposed in between the first hollow metal sleeve and the anchor bar, and in between the first hollow metal sleeve and the second hollow metal sleeve. The infill material dampens energy transfer to and from the concrete reinforcement assembly when employed for structural stability in a concrete structure. A method for repairing a damaged concrete anchor with the concrete reinforcement assembly. A non-transitory computer readable medium having stored thereon a program that, when executed by a computer, causes the computer to execute a method of determining a cyclic response factor of a concrete reinforcement assembly in a concrete structure.


Embodiments include an apparatus for determining a pull-out capacity of a nail disposed in concrete. The apparatus includes control processing circuitry and a Schmidt hammer electrically connected to the control processing circuitry. The Schmidt hammer is configured to strike the nail during a test event and to record a rebound value for the nail. The control processing circuitry is configured to calculate an estimated pull-out strength for the nail using the rebound value of the nail that resulted from the test event, a predetermined nail length, a predetermined nail penetration depth in the concrete, and an estimated predetermined strength of concrete. The apparatus also includes a remote computer configured to communicate with the control processing circuitry and to store an estimated pull-out strength of the nail. The control processing circuitry includes a memory and a database.

A quiet zone can be implemented using a quiet zone transceiver. The quiet zone can have a predetermined perimeter created by the quiet zone transceiver. A smart mobile device can cause an initial alert setting of the smart mobile device to automatically change to a silent alert setting when the smart mobile device is moved into the quiet zone. Additionally, when the smart mobile device is moved out of the quiet zone, the initial alert setting can be restored. The smart mobile device can also be used as the quiet zone transceiver to create the quiet zone if the user of the smart mobile device wishes to create an area in which disturbances such as loud alert settings are limited.

A medical apparatus for extending the neck of a patient without manually lifting the patient. This apparatus has a gel pad assembly encapsulating an inflatable bag connected to two hoses for inflation and deflation purposes. The inflatable bag is positioned beneath the shoulders, thereby lifting the shoulders and hence extending the neck when the inflatable bag is inflated.

Microencapsulated probiotic bacteria protected from degradation by acidic aqueous solutions, high bile salt concentrations, elevated temperatures, and prolonged storage and having an increased anti-bacterial activity as compared to their non-microencapsulated counterparts. The microencapsulated probiotic bacteria comprise probiotic bacteria encapsulated in microcapsules. The probiotic bacteria comprise live Lactobacillus plantarum cells. Each of the microcapsules comprises a matrix of a gelled alginate. The matrix wholly envelops the probiotic bacteria within the matrix. An outer surface of the matrix has a coating consisting essentially of one vegetable oil selected from the group consisting of olive oil and canola oil, or an outer surface of the matrix is treated with sodium chloride. The microencapsulated probiotic bacteria have an average particle size of less than 1000 microns (m) in diameter.

Non-alcoholic fatty liver disease (NAFLD) is a progressive disease that encompasses a spectrum of liver diseases, ranging from simple steatosis to non-alcoholic steatohepatitis (NASH). Data related to survival in children are scarce, but these data firmly associate NAFLD with higher risks of hepatic and non-hepatic morbidities and mortalities compared with the general population. More recently, the association between NAFLD and cardiovascular disease among children has increasingly been recognized. Given that obesity is a major risk factor for the disease, paediatric NAFLD is becoming a global issue, paralleling the dramatic rise in obesity worldwide. NASH, which is more common in obese children, has the potential to advance to liver fibrosis and failure. It is unclear why certain patients undergo such transformation but this susceptibility is likely related to an interaction between a genetically susceptible host and the surrounding environment. Currently, treatment is largely conservative and includes lifestyle modification, attainable through healthy weight reduction via diet and exercise. In this review, current knowledge about NAFLD in children is summarized. This review aims to increase the awareness of the medical community about a hidden public health issue and to identify current gaps in the literature while providing directions for future research. © 2015 World Obesity.


A system includes a display layer disposed beneath one or more layers of a road that is configured to output light to illuminate an upper surface of the road. One or more vertical cylindrical voids extend from the display layer to the upper surface of the road providing a path for the light from the display layer to reach the upper surface of the road. Circuitry is configured to determine a traffic scheme for the road based on traffic data received from one or more sources. Control signals are issued to the display layer to control illumination of the upper surface of the road in accordance with the traffic scheme. Traffic scheme-specific values are output to a smart vehicle corresponding to one or more smart vehicle algorithms.


A histopathology system includes an elongated, cylindrical probe having scanners connected to a distal end of the probe and configured to capture digital images of tissue, a mesh net connected to the distal end of the probe and configured to grasp tissue, and control circuitry configured to expand and contract the mesh net to grasp the tissue being examined. The system includes an outer sheath into which the probe is inserted having one or more tabs extending from the outer sheath to affix the outer sheath at one or more locations. An elongated, cylindrical introducer device guides the outer sheath through a bodily orifice or surgical incision when the introducer device is inserted into the outer sheath. At least one server with processing circuitry is configured to digitally stain a tissue image obtained by the scanners of the tissue, and match the tissue images to stored tissue samples.
