PURPOSE: To evaluate the effects on cost, and number of primary and supplementary neuroradiologic examinations, after introducing MR imaging as the primary modality in the evaluation of the lumbar spine. MATERIAL AND METHODS: Two 5-month periods were compared: period 1--before MR; and period 2--after introduction of a 2nd MR device. In period 1, patients were examined with myelography and/or CT af

Hibernomas are benign tumors with morphological features resembling brown fat. They consistently display cytogenetic rearrangements, typically translocations, involving chromosome band 11q13. Here we demonstrate that these aberrations are associated with concomitant deletions of AIP and MEN1, tumor suppressor genes that are located 3 Mb apart and that underlie the hereditary syndromes pituitary ad

Background: Narayanan & Raman (2004) present what they call an approach to treat incentive misalignments. It consists of three steps: Accept the premise, Pinpoint the cause, and Align or redesign. The first step, accept the premise, is simply acknowledging that there is such a thing as incentive misalignments. The second step, pinpoint the cause, is the process of identifying and describing w

This paper investigates the impact of the completion of the liberalized European Internal Electricity Market on Integrated Resource Planning (IRP) and Demand-Side Management (DSM). The results presented are part of the outcomes of a study analyzing the possibilities of IRP and DSM in this new industry environment. The study, finished in May 2000, is based on empirical surveys of both the present a

The deactivation of a diesel SCR (Selective Catalytic Reduction) catalyst by impregnation with CaSO4 was studied. The loss in activity after 2729 h of use on the engine was lower than when deactivated by impregnation. This was the case even if the amount of Ca in the catalyst was high after use on the engine. In the used catalyst a surface layer of CaSO4 was built up on the monolith during use. Th

Osteoarthritis is a harmful joint disease but prediction of disease progression is problematic. Currently, there is only one modeling framework which can be applied to predict the progression of knee osteoarthritis but it only considers degenerative changes in the collagen fibril network. Here, we have developed the framework further by considering all of the major tissue changes (proteoglycan con

With improvements in cancer treatment and supportive care, a growing population of survivors of childhood cancer at risk for significant and potentially life-threatening late effects has been identified. To provide a current snapshot of the models of care from countries with varying levels of resources and health care systems, stakeholders in childhood cancer survivorship clinical care and researc

Background: Diminished foot somatosensation contributes to balance deficits and increased fall risk. However, it remains unclear if the 256-Hz tuning fork is adequate to measure, in the outpatient clinical setting, somatosensation in relatively healthy elderly. Aims/Objectives: To evaluate the performance of the 256-Hz tuning fork compared to other measures of somatosensation and balance. Material

The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti-kt algorithm with radius parameter R=0.4 and required to have

A search for a heavy resonance decaying into WZ in the fully leptonic channel (electrons and muons) is performed. It is based on proton–proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 36.1 fb−1. No significant excess is observed over the Standard Model predictions and limits are

Direct searches for lepton flavor violation in decays of the Z boson with the ATLAS detector at the LHC are presented. Decays of the Z boson into an electron or muon and a hadronically decaying τ lepton are considered. The searches are based on a data sample of proton-proton collisions collected by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb-1 at a cen

Upcycling is a process in which used or waste products and materials are repaired, reused, repurposed, refurbished, upgraded and remanufactured in a creative way to add value to the compositional elements. It has been part of human life throughout history, and the past few years have seen its revival, driven by multiple factors including growing concern for the environment and resource scarcity. U

Two Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA) products i.e. 3-hourly TRMM 3B42 and monthly 3B43 data were validated using 39 rain gauge stations in the Caspian Sea Region (CSR) in Iran with complex topography. The period 1999-2003 were selected. The validations were performed at monthly and annual scales. Results showed that both TRMM 3B42 and 3B43 can

Massive multiple-input multiple-output (MIMO) arrays are becoming critical elements in cellular base station infrastructure. We utilize the theory of characteristic modes (TCM) to design a novel tri-modal broadside antenna element which is suitable for the construction of compact massive MIMOarrays. The proposed antenna element consists of three ports which is formed by reviewing an existing compa

Based on the experiences of insufficient burnout in industrial fluidized bed furnaces despite adequate mixing and availability of oxidizer, the influence of potassium on CO and H2 oxidation in combustion environments was investigated. The combustion environments were provided by a laminar flame burner in a range relevant to industrial furnaces, i.e. 845 °C to 1275 °C and excess air ratios ranging

Human type 1 diabetes mellitus (T1DM) arises through autoimmune destruction of pancreatic β cells and is modeled in many respects by the lymphopenic and spontaneously diabetic BioBreeding (BB) DRlyp-lyp rat Previously, preonset expression profiling of whole DRlyp-lyp pancreatic lymph nodes (PLN) revealed innate immune activity, specifically that of mast cells and eosinophils. Furthermore, we obser
