"Permeating all community activities"? Comparing events and programming in Westminster and Tower Hamlets public libraries

A comparative study of events and programming in two London public library services, Westminster and Tower Hamlets, is reported. The two services offer the same proportion of 'engagement' programming. Tower Hamlets operates a novel service model, though one with long antecedents, integrating library, learning and cultural services. Its extensive programmes of educational and special events have led to a great increase in visitors, though not to a corresponding increase in use of core library services

The active muon shield in the SHiP experiment

The SHiP experiment is designed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. An essential task for the experiment is to keep the Standard Model background level to less than 0.1 event after $2\times 10^{20}$ protons on target. In the beam dump, around $10^{11}$ muons will be produced per second. The muon rate in the spectrometer has to be reduced by at least four orders of magnitude to avoid muon-induced combinatorial background. A novel active muon shield is used to magnetically deflect the muons out of the acceptance of the spectrometer. This paper describes the basic principle of such a shield, its optimization and its performance.Peer Reviewe

КЛИНИЧЕСКИЕ ПРОЯВЛЕНИЯ, ИНТЕНСИВНОСТЬ ПРОЦЕССОВ ПЕРЕКИСНОГО ОКИСЛЕНИЯ ЛИПИДОВ И ОСОБЕННОСТИ СИНТЕЗА ОКСИДА АЗОТА У БОЛЬНЫХ РОЖЕЙ

65 patients with a diagnosis of erysipelas. Examination of the patients included an analysis of lipid peroxidation products (common polyene, diene conjugates, and conjugate ketodieny trieny, Schiff bases), antioxidant defense system (enzymatic activity of superoxide dismutase) and nitric oxide metabolites (nitrates and nitrites). It was established that imbalance between excess activated lipid peroxidation and inadequate functioning of antioxidant defense system was remained during the entire period of the disease. The relationships between nitric oxide and lipid peroxidation were established. It was proved the advisability of developing and introducing new, improved schemes of pathogenetic therapy of erysipelas.Обследовано 65 больных рожей. В периферической крови определялось содержание продуктов перекисного окисления липидов (общие полиеновые, диеновые конъюгаты, кетодиены и сопряженные триены, основания Шиффа), состояние антиоксидантной защитной системы (ферментативная активность супероксиддисмутазы), а также метаболитов оксида азота (нитратов и нитритов). Установлено, что на протяжении всего периода болезни сохраняется выраженный дисбаланс между избыточно активированными процессами липопероксидации и недостаточно функционирующей антиоксидантной защитной системой. Установлена взаимосвязь между нитроксидергическими процессами и процессами липопероксидации. С учетом полученных данных обоснована целесообразность разработки и внедрения новых, более совершенных схем патогенетической терапии рожи

Comparison of stimulated parotid salivary gland flow rates in normotensive and hypertensive persons

Although hypertension is a prevalent condition among the elderly, little is known with respect to the influence of hypertension on oral health and function. Therefore a study was conducted that compared stimulated parotid salivary flow rates in elderly persons (65 years and older) from two diverse populations who are normotensive, mild, and severe hypertensive. The normotensive group consisted of 45 healthy subjects with systolic blood pressures of less than 140 mm Hg and diastolic pressures less than 90 mm Hg. The mildly hypertensive group consisted of 14 otherwise healthy subjects with either systolic pressures greater than 140 mm Hg or diastolic pressures greater than 90 mm Hg. The severely hypertensive group consisted of 10 otherwise healthy subjects with either systolic pressures greater than 180 mm Hg and/or diastolic pressures greater than 100 mm Hg. All three groups were not taking any prescription or nonprescription medications. Samples of 2% citrate-stimulated parotid saliva were collected from each subject. The results showed no significant differences in stimulated parotid flow between normotensive, mildly hypertensive, and severely hypertensive subjects. These results suggest that hypertension per se has no influence on stimulated parotid salivary gland flow rates in otherwise healthy, elderly unmedicated white and African-American persons.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31510/1/0000432.pd

Saliva-based colorimetric test as an index of gingival inflammation in epidemiologic studies

– There is a pressing need for a reliable, low-cost method of assessing the gingival and periodontal status of large population groups. Existing indexes, despite their value in dental public health, are still too subject to examiner variability for use by uncalibrated examiners. This study describes an evaluation of a quick, inexpensive, extraoral colorimetric test for gingival inflammation, based on a reaction between saliva and the test material. It could probably be applied by non-professional personnel. In this study, the test was applied to a population of elementary schoolchildren, denial hygiene students and faculty, and adult inmates of two correctional institutions. These populations were chosen on the assumption that they would exhibit varying intensities of gingival inflammation. Values obtained from the colorimetric test carried out by one researcher were compared with Gingival Index (GI) scores observed by a different examiner. Results suggest that the colorimetric test may be a valid, reliable means of detecting major differences in the prevalence of gingival inflammation in most adult populations, although having little, if any, useful application among children at the mixed dentition stage.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73489/1/j.1600-0528.1978.tb01169.x.pd

The diagnostic suitability of a xerostomia questionnaire and the association between xerostomia, hyposalivation and medication use in a group of nursing home residents

The study objective was to explore the diagnostic suitability of the Xerostomia Inventory and the association between xerostomia, hyposalivation and medication use in a group of nursing home residents. A cross-sectional study was carried out in 50 physically impaired nursing home residents (20 men) with a mean age of 78.1 years (range, 53–98) in The Netherlands. The Xerostomia Inventory-Dutch version was completed for all residents and the data were subjected to exploratory factor analysis to determine the diagnostic suitability. Residents’ data on xerostomia, whole saliva secretion rates and hyposalivation-related medications used were collected and statistically analyzed. The diagnostic suitability of the Xerostomia Inventory-Dutch version appeared restricted. The prevalence of xerostomia was 52%, without gender and age difference. The prevalence of hyposalivation was 24% for resting, 60% for chewing-stimulated and 18% for acid-stimulated whole saliva. All whole saliva secretion rates were significantly lower in women than in men and in older than in younger residents. Forty-four percent of all medications used were hyposalivation-related and women used significantly more medications than men. Xerostomia was significantly negatively correlated with the resting whole saliva secretion rate. The number of hyposalivation-related medications used was not significantly correlated with the various whole saliva secretion rates. In nursing home residents, xerostomia, hyposalivation and using hyposalivation-related medications seem common and partially associated features

A facility to Search for Hidden Particles (SHiP) at the CERN SPS

A new general purpose fixed target facility is proposed at the CERN SPS accelerator which is aimed at exploring the domain of hidden particles and make measurements with tau neutrinos. Hidden particles are predicted by a large number of models beyond the Standard Model. The high intensity of the SPS 400~GeV beam allows probing a wide variety of models containing light long-lived exotic particles with masses below ${\cal O}$(10)~GeV/c$^2$, including very weakly interacting low-energy SUSY states. The experimental programme of the proposed facility is capable of being extended in the future, e.g. to include direct searches for Dark Matter and Lepton Flavour Violation.Comment: Technical Proposa

Genotypic and phenotypic heterogeneity in Streptococcus mutans isolated from diabetic patients in Rome, Italy

Our study focuses on the antimicrobial susceptibility, genotypic and phenotypic heterogeneity, and serotype classification of the Streptococcus mutans isolated from type II diabetic patients (n = 25; age 42-68). Eighty-two percent of isolates were classified as serotype c. No serotype k was present. Macrorestriction analysis of genomic DNA of the isolates exhibited a clonal diversity that paralleled the phenotypic heterogeneity, which was also assessed in terms of biofilm forming ability. Isolates were susceptible to all the classes of antibiotics. In conclusion a great heterogeneity and no antimicrobial resistance were apparent in the considered S. mutans strains from diabetic patients
