    An analysis of РВВ clinical features showed that their total duration was 4.1 ± 0.3 weeks. In children with RB, the duration of exacerbations did not differ significantly and was 3.8 ± 0.4 weeks. In patients with CB, the annual number of bronchitis and the total duration of cough were two times higher than in patients with RB. Bacteriological analysis showed that Streptococcus pneumonia was the most frequent causative agent of the disease in children with PBB and RB. In children with exacerbation of CB, Haemophilus influenzae was more commonly identified. At the same time, such a representative of the normal bronchial microbiome as Aerococcus viridans, was identified in 81.0 % of PBB patients, in 33.3 % of RB patients, and in 8.7 % of CB patients

    Представлені результати досліджень по вивченню впливу різного рівня мінеральних речовин, що додавалися до фонового раціону бичків на надходження хімусу, сухої речовини, органічних речовин, сирого протеїну із передшлунків до дванадцятипалої кишки. Перед початком дослідів тварини були прооперовані з накладенням анастомозів на початку дванадцятипалої кишки, на відстані 8 – 12 см від сичугу, до впадіння в кишечник підшлункової залози.У фізіологічних дослідах вивчали перетравність органічних речовин під впливом додавання до фонового раціону хлориду натрію, хлориду кобальту, сульфатів міді і цинку, як окремо, так і в комплексі. Відмічено, що зі збільшенням об'єму хімусу, що надходив до дванадцятипалої кишки перетравність органічних речовин в передшлунках знижувалася, що підтверджується зворотною кореляційною залежністю.Встановлено, що додавання до фонового раціону мінеральних солей призвело до збільшення надходження в тонкий кишечник органічних речовин, як в цілому, так і окремо сирого протеїну.З'ясовано, що додавання до фонового раціону мінеральних речовин призвело до активізації процесів біосинтезу мікробіального білку в передшлунках бичків з використанням ендогенних джерел азоту. Представлены результаты исследований по изучению влияния различного уровня минеральных веществ, добавлявшихся к фоновому рациону бычков на поступление химуса, сухого вещества, органических веществ, сирого протеина из преджелудков в двенадцатиперстную кишку. Перед началом опытов животные были прооперированы с наложением анастомозов в начале двенадцатиперстной кишки, на расстоянии 8–12 см от сычуга, до впадения в кишечник поджелудочной железы.В физиологических опытах изучали переваримость органических веществ под влиянием добавления к фоновому рациону хлорида натрия, хлорида кобальта, сульфатов меди и цинка, как по отдельности, так и в комплексе. Отмечено, что с увеличением объема химуса, поступающего в двенадцатиперстную кишку, переваримость органических веществ в преджелудках снижалась, что подтверждается обратной корреляционной зависимостью. Установлено, что добавление к фоновому рациону минеральных солей привело к увеличению поступления в тонкий кишечник органических веществ в целом, так и в отдельности сырого протеина.Выяснено, что добавление к фоновому рациону минеральных веществ привело к активизации процессов биосинтеза микробиального белка в преджелудках бычков с использованием эндогенных источников азота. Results of researches on studying the influence of various levels of the mineral substances that were added to a diet of bull–calves on getting of chyme, dry substances, organic substances, raw protein from prestomachs to duodenum are presented. Before the experiment animals have been operated with imposing of anastomosis at the beginning of a duodenum, at the distance of 8–12 cm from abomasus before the falling of pancreas into intestines.Nowadays rationing of mineral food of animals is carried out by two ways: by amount of mineral substances on one animal a day or by its quantity on one kilogram of the consumed solid forage.In our experiments mineral substances were brought in 1 kg of the consumed solid forage as it allows to create a certain concentration of the studied connections in the substance of the rumen.During the preparatory period animals were on the diet for two weeks, then within 7 days they were used in experiments to define digestibility of nutrients in gastrointestinal tract. After completion of experiment on digestibility there was a physiological experiment to determine daily volume and structure of the chyme proceeding through inosculation of chyme. In forage and on average daily tests of a duodenal chyme and faeces the content of solids and also organic substances (with the difference between amount of solid and mineral substances) of a raw protein, raw fat, raw cellulose and the anazotic extractive substances by common techniques of the zoochemical analysis were determined.In physiological experiments digestibility of organic substances under the influence of addition of chloride of sodium, chloride of cobalt, sulfates of copper and zinc to a diet separately and in the complex were studied. It was indicated that with the increase of chyme, coming to a duodenum, digestibility of organic substances in prestomachs decreased that was also confirmed by the inverse correlation dependence. It was proved that addition of mineral salts to a diet has led to increase of getting of organic substances in a small intestine as a whole and also of a raw protein.It was found that addition of mineral substances to a diet has led to activation of processes of biosynthesis of microbiological protein in prestomachs of bull–calves with the use of endogenous sources of nitrogen.

    This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPThe CMS silicon tracker, consisting of 1440 silicon pixel and 15 148 silicon strip detector modules, has been aligned using more than three million cosmic ray charged particles, with additional information from optical surveys. The positions of the modules were determined with respect to cosmic ray trajectories to an average precision of 3–4 microns RMS in the barrel and 3–14 microns RMS in the endcap in the most sensitive coordinate. The results have been validated by several studies, including laser beam cross-checks, track fit self-consistency, track residuals in overlapping module regions, and track parameter resolution, and are compared with predictions obtained from simulation. Correlated systematic effects have been investigated. The track parameter resolutions obtained with this alignment are close to the design performance.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

    Get PDF
    The performance of the Local Trigger based on the drift-tube system of the CMS experiment has been studied using muons from cosmic ray events collected during the commissioning of the detector in 2008. The properties of the system are extensively tested and compared with the simulation. The effect of the random arrival time of the cosmic rays on the trigger performance is reported, and the results are compared with the design expectations for proton-proton collisions and with previous measurements obtained with muon beams
