Recent results of the searches for Supersymmetry in final states with one or two leptons at CMS are presented. Many Supersymmetry scenarios, including the Constrained Minimal Supersymmetric extension of the Standard Model (CMSSM), predict a substantial amount of events containing leptons, while the largest fraction of Standard Model background events -which are QCD interactions -gets strongly reduced by requiring isolated leptons. The analyzed data was taken in 2011 and corresponds to an integrated luminosity of approximately L = 1 fb −1 . The center-of-mass energy of the pp collisions was √ s = 7 TeV.
Steatite ceramic materials are promising for applications as dielectrics in setups exposed to ionizing radiation. These materials are multiphase systems which include crystalline and amorphous phases [1].Our aim in the present work was to study, by optical spectroscopy, the nature of radiation defects that form in steatite ceramic under high-dose y and mixed n-y irradiation. Steatite ceramic is opaque. For this reason, optical absorption, which in general is characterized by diffuse reflection, was studied by measuring the diffuse reflection spectra.Experimental procedure. SK-1 steatite ceramic has a fine-crystalline uniform structure. The main phases are crystals of magnesium metasilicate MgSiO 3 and glass with a complicated composition. Magnesium metasilicate crystals have an average grain size of 3-8 t.tm and occupy 60-70% of the volume of the ceramic [1, 2]. Samples in the form of 10xl0xl mm plates or 15 mm in diameter and 2 mm thick disks were used. The diffuse refleciion spectra of the unirradiated and irradiated ceramic samples were investigated in the wavelength range 200--700 nm using an SF-4 spectrograph with a PDO-1 diffuse reflection attachment, q[he light beam was detected with an FI~U-39 photomultiplier. Initial samples of SK-1 ceramic were used as the standard. The ceramic samples were irradiated by y-rays from 6~ and mixed.n-y irradiation from a reactor. The ),-dose was varied in the range 106-101~ R, the neutron fluence during reactor irradiation was 1017-102~ cm -2. The degree of light reflection was estimated from the relative reflection coefficient R = (lirrl Iunirr)• where lir r and Iuni~ ~ are, respectively, the intensity ofthe reflected light from the irradiated and unirradiated sample, respectively.Results and discussion. In the initial state the SK-1 steatite ceramic had a light color. After irradiation the samples acquired a brown color, whose density increased with the irradiation dose. After ),-irradiation additional absorption bands are observed in the UV region with a maximum at ~, = 220 and 260 nm and in the visible region of the spectrum with a maximum at 400-500 nm (Fig. 1). The intensity of the absorption bands increased with the y-dose (see curves 1-3 --107, 109, 1.5.10 l~ R, respectively). Similar absorption bands are also observed after irradiation in a reactor (1019 cm -2, curve 4). In previous investigations glass with a composition close to the glass phase of SK-1 ceramic was investigated by thermoluminescence and ESR. Thermoluminescence and ESR peaks were not observed in this glass after irradiation, but a paramagnetic absorption signal with g = 2.0012 was detected in the ceramic [3]. The presence of structural groups of the ceramic-oxygen framework in the magnesium metasilicate suggests that the observed absorption bands are associated with disruptions in the SiO 4 clusters [4]. Color centers, which absorb light near 220 and 260 nm, were observed in crystalline quartz and in quartz and silicate glasses under irradiation with ionizing radiation [5, 6]. They are associated ...
Objectiveto show the instability of an epizootic situation on rabies casesof animals in the Republic of Azerbaijan, on the example of thecases analysis in Electronic Integrated Disease Surveillance System(EIDSS) electronic reporting systemIntroductionRabies is an infectious disease which was and remains to be oneof the most serious diseases of all species of hematothermal animalsand humans, in many regions of the world. The epizootic situation onrabies in the Republic of Azerbaijan has been unfavorable for manyyears, which is confirmed by scientific data and the veterinary casesreporting in the EIDSS system. This system was introduced in thecountry in 2009 and is the electronic System of disease control. Theprogram allows to provide monitoring and prevention of diseaseswithin the concept “One World - One Health System” by integrationof systems of observation of animal diseases, human diseases, anddisease carriers.MethodsOn the basis of the data on rabies cases entered in special formsand also aggregative data collected on anti-rabies vaccination, theanalysis of information on quantity of cases and their prevalence onadministrative and territorial units (rayons) of the country is carriedout. The graphical analysis (charts and the map) on the basis ofnecessary criteria are constituted in the analyses module, visualizationof the AVR reporting and in the Microsoft Excel program.ResultsThe analysis of the rabies cases confirmed at the Virologydepartment of the Republican Veterinary Laboratory shows thatrabies has been identified in 36 cases in 2015, 25 cases in January- June, 2016, in total 61 cases has been registered for the periodof “January 2015 – June 2016”. An epizootologically unfavorablesituation is revealed in 27 regions. The most unfavorable situation isthe northwest regions of the country, the most part of which is coveredwith mountainy-forest area with domination of wild fauna. Specificstructure of animals: dogs – 31 cases in 19 areas (51%), cattle – 21cases in 12 areas (34%), a small cattle-1 case (2%), wild animals(specify types) - 8 cases in 8 areas (13%) that is visually shown oncharts 1 and 2. The cattle were bitten by wolves and jackals.ConclusionsThus, prevalence of rabies cases of different species of animalsin the country, once again proves natural and focal character of thedisease: the reservoir of rabies is in the wild nature and geographicalconditions impact the spread of rabies.Cases of rabies in animals are registered annually. In 2015,vaccination captured about 250000 dogs, and 244400 dogs werevaccinated in the first 6 months of 2016. Despite a huge group ofvaccinations, restriction of rabies spread isn’t observed and thetendency is trending to the increase of rabies case indicators amongstthe dogs.It is necessary to pay close attention to preventive vaccination ofdomestic (including non-productive) animals. If materiel resourcesare available, it is possible to carry out the vaccination of the cattlein the territories adjacent to the forests. In the threatened territorieswith woodlands, there is no alternative to oral vaccinations, whichis confirmed by positive experience of many countries. There is anextreme need of carrying out of oral vaccination of wild carnivorousanimals with obligatory control of the immune status.
