Charged-particle multiplicities in pp interactions measured with the ATLAS detector at the LHC
2011
Measurements are presented from proton–proton collisions at centre-of-mass energies of \sqrt{s} = 0.9 , 2.36 and 7 TeV recorded with the ATLAS detector at the LHC. Events were collected using a single-arm minimum-bias trigger. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the relationship between the mean transverse momentum and charged-particle multiplicity are measured. Measurements in different regions of phase space are shown, providing diffraction-reduced measurements as well as more inclusive ones. The observed distributions are corrected to well-defined phase-space regions, using model-independent corrections. The results are compared…
ATLAS measurements of the properties of jets for boosted particle searches
2012
Measurements are presented of the properties of high transverse momentum jets, produced in proton-proton collisions at a center-of-mass energy of √s=7 TeV. The data correspond to an integrated luminosity of 35 pb−1 and were collected with the ATLAS detector in 2010. Jet mass, width, eccentricity, planar flow and angularity are measured for jets reconstructed using the anti-kt algorithm with distance parameters R=0.6 and 1.0, with transverse momentum pT>300 GeV and pseudorapidity |η|<2. The measurements are compared to the expectations of Monte Carlo generators that match leading-logarithmic parton showers to leading-order, or next-to-leading-order, matrix elements. The generators describ…

Recent trends in rapid detection of influenza infections by bio and nanobiosensor
2018
Abstract A literature update has been made about the progress and improvements in the use of biosensors for sensitive, rapid and specific detection of influenza virus. Background information about influenza virus and its structure together with a general discussion about the characteristics and significant aspects of different types of biosensors were used as a frame to put inside the main recent developments on the use of nanobiosensors for the detection of influenza virus. Working criteria of biosensors and their applications in different species of influenza virus diagnosis have been the primary concern of this review, which critically discusses the main advantages and limitations of stu…
Formation of basement membrane in extracapillary proliferates in rapidly progressive glomerulonephritis
1977
In the extracapillary proliferations (crescents) of the glomeruli in glomerulonephritis, basement membranes appear and in addition "secretory bodies" are formed in the cisternae of the rough endoplasmatic reticulum. The findings permit the conclusion that proliferated visceral epithelial cells are involved in the crescent formation to a greater extent than previously assumed.

The influence of the cycloid disc bearing type on the cycloidal speed reducer efficiency
2021
The robotics industry has experienced a rapid expansion in the last decade. As a result, the market of speed reducers with high gear ratios, high precision and a compact design is growing rapidly. In addition to these characteristics, it is very important for gear trains to have high efficiency. Because of their compact design, cycloidal speed reducers are not exposed to axial forces, which is their important characteristic. This means that radial bearings can be used in their supports. The bearing type has significant effects not only on the design and dimensions of the cycloid speed reducer but also on its efficiency. In this paper, an analysis of power losses for different types of rolli…
Patterns of weight cycling in youth Olympic combat sports: a systematic review
2022
Abstract Background Patterns of weight cycling in adult combat sports have been extensively studied, yet data on this matter in youth combat athletes is rather scarce. Methods PubMed, EBSCOhost and Web of Science were used to retrieve relevant data. Eligible studies had to record the methods used to elicit rapid weight loss (RWL) and/or record the oscillations in bodyweight during the RWL phase. Only studies conducted in the context of an official competition were considered for inclusion in the present review. Results RWL is highly prevalent in children and adolescent combat athletes, ranging from 25 to 94% depending on the type of combat sport, age and level of competition. These athletes…
A negative rapid urease test is unreliable for exclusion of Helicobacter pylori infection during acute phase of ulcer bleeding
2003
Abstract Background. The reliability of the rapid urease test has not been proven in patients with peptic ulcer bleeding. Some studies show bad diagnostic results with the rapid urease test for gastrointestinal bleeding. Aims. To evaluate the efficacy of the rapid urease test in patients with bleeding gastric or duodenal ulcers. Patients and methods. A total of 96 patients with acute peptic ulcer bleeding without proton pump inhibitor or antibiotic therapy within the last 14 days before bleeding were included into the study. During index endoscopy, specimens for histological and rapid urease test were obtained from the antrum and corpus mucosa of the stomach. Patients were also investigated…
Stool antigen assay (HpSA) is less reliable than urea breath test for post-treatment diagnosis of Helicobacter pylori infection
2002
Summary Background : The diagnostic yield of the stool antigen test (HpSA) in evaluating the results of Helicobacter pylori eradication therapy is controversial, but many studies have used only the 13C-urea breath test (13C-UBT) as a gold standard which has greatly reduced their relevance. Aim : To compare the reliability of HpSA and 13C-UBT in patients post-treatment using biopsy-based methods as reference tests. Methods : A total of 100 consecutive dyspeptic patients (42 male and 58 female; mean age, 56 ± 18 years) were enrolled in our study. All patients were H. pylori positive on the basis of at least two biopsy-based methods, and underwent 1 week of treatment with various triple therap…
