Using the Tenth Amendment to Prevent Forest Fires: An Analysis of the PropertyClause and Tenth Amendment in United States v. Board of County Commissionersof County of Otero
In July 2016, residents of Timberon, a small town located on the edge of Lincoln National Forest in Otero County, New Mexico, returned home to find their houses reduced to ashes. They were victims of a forest fire that had quickly spread due to the dry, arid conditions in Otero County. Unfortunately, such scenes are all too common. Wildfires burning throughout the country have become a growing national concern. Time and time again people are forced to evacuate their homes because forest fires, fueled by dry undergrowth, have burned their communities. When a community is faced with such dangers it must protect itself. This same rationale motivated the Board of County Commissioners of the County of Otero to take preemptive measures to thin and clear dangerous dry undergrowth that posed a serious conflagratory threat of causing the same destruction residents of Timberon experienced. Otero County’s protective measures, however, were halted by the Federal Government, who used authority granted to it by the Property Clause of the Federal Constitution to assert complete authority over National Forest land in Otero County
Autoimmune liver disease in a sicilian woman.
Autoimmune hepatitis (AIH) is a chronic liver disease characterized by clinical features analogue to viral and non-autoimmune
liver disorders, but with distinct sero-autoimmunologic properties. The disease results from a network of complex interactions
involving genetic predisposition, triggering factors, autoantigens and immunoregulatory system. Diagnosis of AIH relies on positive
autoantibodies determination and on liver core biopsy histological appearance. Corticosteroid and immunosuppressive drugs are generally useful in the treatment of disease. However, when inflammation cannot be controlled, progression from chronic hepatitis to cirrhosis is often observed and hepatocellular carcinoma may appear at the end stage. Here we reported a case of a woman, affected
with AIH. The patient presented features of chronic liver disease of neither viral nor alcoholic aetiology. Serum evidence of hypertraminasemia, hypergammaglobulinemia and specific autoantibodies were the leading points to final diagnosis, which was validated
by liver biopsy. The patient was, finally, successfully treated with steroids
GNAM and OHP: Monitoring Tools for ATLAS experiment at LHC.
ATLAS is one of the four experiments under construction along the Large Hadron Collider (LHC) ring at CERN. The LHC will produce interactions at a center-of-mass energy equal to âs = 14 TeV at 40 MHz rate. The detector consists of more than 140 million electronic channels. The challenging experimental environment and the extreme detector complexity impose the necessity of a common scalable distributed monitoring framework, which can be tuned for the optimal use by different ATLAS sub-detectors at the various levels of the ATLAS data flow. This note presents two monitoring tools that have been developed for this aim within the architecture ATLAS Monitoring Framework and the Data Acquisition System: GNAM and OHP. The first one is a framework for online histogram production; the second one is graphical application for histogram presentation. This tools are now widely used during the ATLAS commissioning and their performances are reported in this not
Hadron detection with a dual-readout fiber calorimeter
In this paper, we describe measurements of the response functions of a
fiber-based dual- readout calorimeter for pions, protons and multiparticle
"jets" with energies in the range from 10 to 180 GeV. The calorimeter uses lead
as absorber material and has a total mass of 1350 kg. It is complemented by
leakage counters made of scintillating plastic, with a total mass of 500 kg.
The effects of these leakage counters on the calorimeter performance are
studied as well. In a separate section, we investigate and compare different
methods to measure the energy resolution of a calorimeter. Using only the
signals provided by the calorimeter, we demonstrate that our dual-readout
calorimeter, calibrated with electrons, is able to reconstruct the energy of
proton and pion beam particles to within a few percent at all energies. The
fractional widths of the signal distributions for these particles (sigma/E)
scale with the beam energy as 30%/sqrt(E), without any additional contributing
terms
