Design, Performance, and Calibration of the CMS Hadron-Outer Calorimeter

The CMS hadron calorimeter is a sampling calorimeter with brass absorber and plastic scintillator tiles with wavelength shifting fibres for carrying the light to the readout device. The barrel hadron calorimeter is complemented with an outer calorimeter to ensure high energy shower containment in the calorimeter. Fabrication, testing and calibration of the outer hadron calorimeter are carried out keeping in mind its importance in the energy measurement of jets in view of linearity and resolution. It will provide a net improvement in missing \et measurements at LHC energies. The outer hadron calorimeter will also be used for the muon trigger in coincidence with other muon chambers in CMS

The meaning of my feelings depends on who I am: work-related identifications shape emotion effects in organizations

Theory and research on affect in organizations has mostly approached emotions from a valence perspective, suggesting that positive emotions lead to positive outcomes and negative emotions to negative outcomes for organizations. We propose that cognition resulting from emotional experiences at work cannot be assumed based on emotion valence alone. Instead, building on appraisal theory and social identity theory, we propose that individual responses to discrete emotions in organizations are shaped by, and thus depend on, work-related identifications. We elaborate on this proposition specifically with respect to turnover intentions, theorizing how three discrete emotions - anger, guilt, and pride - differentially affect turnover intentions, depending on two work-related identifications - organizational and occupational identification. A longitudinal study involving 135 pilot instructors reporting emotions, work-related identifications, and turnover intentions over the course of one year provides general support for our proposition. Our theory and findings advance emotion and identity theories by explaining how the effects of emotions are dependent on the psychological context in which they are experienced

Optical and structural characteristics of tin oxide thin films deposited by filtered vacuum arc and spray pyrolysis

Tin oxide (SnO 2) thin films were deposited on commercial microscope glass and UV fused silica substrates (UVFS) using spray pyrolysis and filtered vacuum arc deposition (FVAD) system. During deposition, the substrates temperature was kept at 400 °C. The structure and composition were determined using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), respectively. The XRD patterns of SnO 2 thin films deposited with the two systems on hot substrates were found to be polycrystalline. The average transmission of the films in the VIS was 80% to 85%. The film optical constants were determined by normal incidence transmission measurements. The refractive indices of FVA deposited films were in the range 2.11 to 2.0, and those of spray deposited ones were 1.97 to 1.93. The extinction coefficients of the deposited films were in the range 0.29 and 0.11 to approximately 0 for FVAD and spray pyrolysis, respectively, depending on wavelengths. The optical band gap, E g, was determined from the dependence of the absorption coefficient on the photon energy at short wavelengths, and were 3.80 eV and 3.90 eV for spray pyrolysis and FVA deposited SnO 2 thin films, respectively. © 2007 WILEY-VCH Verlag GmbH & Co.

Effect of oxytocin administration on nerve recovery in the rat sciatic nerve damage model

PubMed ID: 26466786Background: Growth factors such as nerve growth factor (NGF) and insulin-like growth factor-1 (IGF-1) have been shown to play a role in the healing process of nerve injury. Recent researches have also shown that oxytocin administration activates these growth factors of importance for the healing of nerve tissue. The objective of the present study was to evaluate the effects of oxytocin on peripheral nerve regeneration in rats. Methods: Twenty-four male Sprague-Dawley rats were underwent transection damage model on the right sciatic nerve and defective damage model on the left sciatic nerve. The animals were assigned to one of two groups: control group or treatment group (received 80mg/kg oxytocin intraperitoneally for 12weeks). The sciatic nerve was examined, both functionally (on the basis of climbing platform test) and histologically (on the basis of axon count), 3, 6, 9, and 12weeks after the injury. Also, stereomicroscopic and electrophysiological evaluations were carried out. Results: Significantly greater improvements in electrophysiological recordings and improved functional outcome measures were presented in the treatment group at 12-week follow-up. Stereomicroscopic examinations disclosed prominent increases in vascularization on proximal cut edges in the oxytocin group in comparison with the control group. Higher axon counts were also found in this group. Conclusion: Intraperitoneal oxytocin administration resulted in accelerated functional, histological, and electrophysiological recovery after different sciatic injury models in rats. © 2015 Gümüs et al

Rates of new asthma diagnosis in patients with allergic rhinitis in otorhinolaryngology practice in the Eastern Black Sea region

Background: Allergic rhinitis (AR) is a common disease observed in otorhinolaryngology (ORL) practice. The aim of the study was to determine the rates of new asthma diagnosis in the patient population newly diagnosed with AR in otorhinolaryngology (ORL) practice in the Eastern Black Sea region. Material/Methods: This study retrospectively evaluated the files of patients admitted to an ORL outpatient clinic in Rize, Turkey between April 2011 and June 2012 and who were diagnosed with AR for the first time upon detection of aeroallergen sensitization in the prick test. Within this patient group, the files of patients who were also diagnosed with asthma in the same time period were examined. The files of patients who had previously been diagnosed with or treated for AR and/or asthma and with nasal polyposis and lower respiratory tract disease were excluded from the study. Results: There were 267 patients with a mean age of 37.5±14.9 (10–77 years) diagnosed with AR for the first time in the ORL outpatient clinic. The most common allergens were Dermatophagoides pteronyssinus (81.3% [217/267]), D. farinae (73.8% [197/267]), and grass mix (61.4% [164/267]). Of this patient group, 29.2% were diagnosed with asthma: 15% (40/267) with intermittent asthma, 13.9% (37/267) with mild persistent asthma, and 0.3% (1/267) with moderate persistent asthma. Conclusions: A rate of 29.2% for new asthma diagnoses in the Eastern Black Sea region in patients diagnosed with AR for the first time indicates a need to examine asthma complaints in all patients newly diagnosed with AR in ORL practices. © Med Sci Tech, 2016

Differentiation of chronic and aggressive forms of periodontitis and of smokers and non-smokers by Fourier-transform infrared spectroscopy

<b>Aim:</b> To determine if Fourier-transform infrared spectroscopy (FTIR) could distinguish chronic periodontitis (CP) and aggressive periodontitis (AgP) patients by cross-sectional salivary spectral analyses and to assess the potential confounding influence of smoking on discriminating spectral signatures. <b>Methods:</b> FTIR analysis of saliva collected from patients with CP (n = 18, 7 smokers), AgP (n = 23, 9 smokers) was performed. Smoking status was confirmed by salivary cotinine analysis. Spectral band area analysis, hierarchical cluster analysis was performed. <b>Results:</b> Spectral analyses indicated significantly lower lipid, phospholipid, protein, amino acid, lactic acid, nucleic acid contents in smoker than non-smoker AgP group. Amino acid, phospholipid, lactic acid contents were significantly lower in smoker than non-smoker CP group. Thiocyanate levels successfully differentiated smokers from non-smokers, irrespective of periodontal status. Cluster analysis to discriminate smokers from non-smokers and CP from AgP was highly promising. <b>Conclusions:</b> FTIR can be employed to discriminate smokers from non-smokers and CP from AgP

High-Impedance Surfaces for Above-IC Integration of Cooled Bolometer Arrays at the 350-μm Wavelength

International audienceHigh-impedance surfaces (HIS) are investigated here for the above-IC integration of sub-millimeter-wave (350 µm here) detectors on CMOS electronics using standard thin film manufacturing processes and materials. We demonstrate theoretically and experimentally the efficient optical absorption of a resistive dipole array above an HIS at cryogenic temperature. More specifically, an absorption above 78% in linear polarization is obtained over a bandwidth of 100 µm around a center wavelength of 350 µm. These results confirm the promising performances of HIS structures in the perspective of future polarimetric bolometers in terms of absorption efficiency, bandwidth and cross-polarization discrimination
