Forgiveness in PTSD after man-made traumatic events: a systematic review

Forgiveness has proven to be beneficial for the physical and mental health of individuals. In sufferers of posttraumatic stress disorder (PTSD) after man-made traumatic events, it is often believed to have a positive effect to forgive the transgressor. This systematic review identifies and presents a summary ofthe literature into the association of symptoms of PTSD with forgiveness after man-made traumatic events. The bibliography databases EMBASE, PubMed/Medline, PsycInfo, PsycExtra, Scopus, and Web of Science were searched. Thirteen studies met the inclusion criteria. The review shows significant differences between individual studies regarding the type of trauma, the setting, the forgiveness concept, and the measurement instruments used for PTSD and forgiveness. Only 1 study could not establish a significant correlation between forgiveness and PTSD symptoms. The other studies found that higher forgiveness levels were associated with lower PTSD-related symptoms scores, but other factors have to be taken into account, as demographic variables, the relationship between transgressor and survivor of trauma, the type and severity of trauma, and other variables were also shown to be relevant

Forward Jet Studies in CMS

We present studies of the reconstruction capabilities of the CMS Hadron Forward (HF) calorimeter (3$<\mid \eta\mid<$5) to measure the single inclusive forward jet $p_T$ spectrum and forward-backward (Mueller-Navelet) dijets in $p$-$p$ collisions at 14 TeV. Both observables are sensitive to low-$x$ gluon densities and non-linear QCD evolution in the proton

Performance Studies of Prototype II for the CASTOR forward Calorimeter at the CMS Experiment

We present results of the performance of the second prototype of the CASTOR quartz-tungsten sampling calorimeter, to be installed in the very forward region of the CMS experiment at the LHC. The energy linearity and resolution, as well as the spatial resolution of the prototype to electromagnetic and hadronic showers are studied with E=20-200 GeV electrons, E=20-350 GeV pions, and E=50,150 GeV muons from beam tests carried out at CERN/SPS in 2004. The responses of the calorimeter using two different types of photodetectors (avalanche photodiodes APDs, and photomultiplier tubes PMTs) are compared.Comment: 16 pages, 22 figs., submitted to EPJ-

Forward physics with CMS

We describe several example analyses of the CMS forward physics program: A feasibility study for observing $W$ production in single diffractive dissociation, the analysis of exclusive $\mu\mu$ production and the measurement of very low-x parton distributions and search for evidence of BFKL dynamics with forward jets

Yang-Mills Theory In Axial Gauge

The Yang-Mills functional integral is studied in an axial variant of 't Hooft's maximal Abelian gauge. In this gauge Gau\ss ' law can be completely resolved resulting in a description in terms of unconstrained variables. Compared to previous work along this line starting with work of Goldstone and Jackiw one ends up here with half as many integration variables, besides a field living in the Cartan subgroup of the gauge group and in D-1 dimension. The latter is of particular relevance for the infrared behaviour of the theory. Keeping only this variable we calculate the Wilson loop and find an area law.Comment: 43 pages REVTeX, 6 figure

Preoperative evaluation of cytologically indeterminate thyroid nodules with 18F-FDG PET

Esse artigo tem o objetivo de discutir o papel da tomografia por emissão de pósitrons (PET) com 18F-FDG na avaliação pré-operatória de pacientes com nódulos de tireóide com citologia indeterminada. Para o cálculo da sensibilidade, foram selecionados todos os estudos com pacientes com carcinoma de tireóide. Para o cálculo da especificidade, foram selecionados apenas estudos desenhados para avaliação dos pacientes com nódulos com citologia indeterminada. O achado de captação focal na PET-18F-FDG relacionou-se com a presença de carcinoma de tireóide na maioria dos estudos. A sensibilidade do exame foi bastante alta na detecção de malignidade tireoidiana, porém sua especificidade variou de 0% a 66%, sendo de 39% em estudo brasileiro. Concluindo, os estudos indicam que a PET-18F-FDG pode reduzir o número de tireoidectomias desnecessárias em pacientes com nódulos de tireóide com citologia indeterminada. Entretanto, o percentual relativamente elevado de resultados falso-positivos, o alto custo, a baixa disponibilidade do exame em países em desenvolvimento e a pouca experiência clínica ainda limitam o uso da PET-18F-FDG com essa finalidade.The aim of this article is to discuss the role of 18F-FDG Positron Emission Tomography (PET) in the preoperative evaluation of patients with cytologically indeterminate thyroid nodules. All studies with patients with thyroid cancer were selected to the calculation of sensitivity. Only studies aiming to evaluate patients with thyroid nodules whose cytological result was indeterminate were selected to establish the specificity. The finding of focal 18F-FDG uptake at PET was associated with the presence of thyroid malignancy in most of the studies. The sensitivity of the exam to the detection of thyroid malignancy was extremely high, but the specificity varied from 0 to 66%. In our experience, the specificity was 39%. In conclusion, the studies suggest that 18F-FDG PET can reduce the number of unnecessary thyroidectomies performed in patients with cytologically indeterminate thyroid nodules. However, the relatively high percentage of false positive results, the high costs, the low availability of this exam in developing countries and the low clinical experience still restrict the use of 18F-FDG PET when recommended with this aim

Radiation-Hardness Measurements of High OH−OH^{-} Content Quartz Fibres Irradiated with 24 GeV Protons up to 1.25 Grad

We investigated the darkening of two high OH- content quartz fibres irradiated with 24 GeV protons at the Cern PS facility IRRAD. The two tested fibres have a 0.6 mm quartz core diameter, one with hard plastic cladding (qp) and the other with quartz cladding (qq). These fibres were exposed at about 1.25 Gigarad in 3 weeks. The fibres became opaque below 380nm, and in the range 580-650 nm. The darkening under irradiation and damage recovery after irradiation as a function of dose and time are similar to what we observed with electrons. The typical attenuation at 455 nm are 1.44 + - 0.22 and 2.20 + - 0.15 dB/m at 100 Mrad for qp and qq fibres, respectively. The maximum damage recovery is also observed near this wavelength
