This paper reports on the structure of the autonomous station for monitoring artificial gamma activity in surface water bodies for the purposes of emergency preparedness of the Czech Republic. A simple design based on the NaI(Tl) submersible detector powered by a combined solar and wind source has been employed. Data transfer is provided by a satellite connection. The detection capabilities of the device have been tested for various unfavourable conditions, and the detection limits have been lowered by using the noise adjustment singular value decomposition (NASVD) method. The detection capabilities of the device fulfil the legal requirements for emergency monitoring, and are almost equal to the detection capabilities of other available devices with a more complicated and less versatile structure.

A set of measurements have been conducted to determine the activity-level of natural and artificial radionuclides in some baby foods commercialized in Italy. The measurements have been carried out usi...
Two complementary measurement systems-built upon an autonomous floating craft and a tethered balloon-for lake research and monitoring are presented. The autonomous vehicle was assembled on a catamaran...
Microbiological water quality is traditionally assessed using culture-based enumeration of faecal indicator bacteria such as Escherichia coli. Despite their relative ease of use, these methods require...
The determination of the presence of artificial radionuclides in the air is mainly accomplished by using gamma spectrometry analysis of filter samples. This work suggests very fast, reliable and effic...
Gamma band activity (30-50 Hz) plays an essential role in brain development and function, but neither the early postnatal development nor subject and environmental factors influencing this developme...
The aim of the project is to undertake clinical development of a hybrid compact gamma camera that combines gamma ray and optical imaging. It is an extension of the previous pilot study usi...
The purpose of this study is to examine the antifungal activity of recombinant interferon-gamma 1b (rIFN-gamma 1b) given with standard antifungal therapy.
Dry eye is a significant adverse effect of isotretinoin causing patients to use ophthalmic medications. For this reason, many patients using isotretinoin are referred to ophthalmology clin...
Hyaluronic acid, a natural polymer, helps to maintain ocular surface hydration and can already be found in several artificial tears recommended to alleviate symptoms of dry eye. A recent h...
To determine safety and tolerance of administering aerosolized recombinant interferon gamma (IFN-gamma) for 4 weeks in patients with AIDS. To examine activation of alveolar macrophages by ...
Recording the locations and measurements of electrical activity in the EPICARDIUM by placing electrodes on the surface of the heart to analyze the patterns of activation and to locate arrhythmogenic sites.
Devices for simulating the activity of the pancreas. They can be either electromechanical, consisting of a glucose sensor, computer, and insulin pump or bioartificial, consisting of isolated islets of Langerhans in an artificial membrane.
Specific molecular sites on the surface of various cells, including B-lymphocytes and macrophages, that combine with IMMUNOGLOBULIN Gs. Three subclasses exist: Fc gamma RI (the CD64 antigen, a low affinity receptor), Fc gamma RII (the CD32 antigen, a high affinity receptor), and Fc gamma RIII (the CD16 antigen, a low affinity receptor).
Glycoproteins attached to the surface coat of the trypanosome. Many of these glycoproteins show amino acid sequence diversity expressed as antigenic variations. This continuous development of antigenically distinct variants in the course of infection ensures that some trypanosomes always survive the development of immune response to propagate the infection.
A homolog of ALPHA-SYNUCLEIN that plays a role in neurofilament network integrity. It is overexpressed in a variety of human NEOPLASMS and may be involved in modulating AXON architecture during EMBRYONIC DEVELOPMENT and in the adult. Gamma-Synuclein may also activate SIGNAL TRANSDUCTION PATHWAYS associated with ETS-DOMAIN PROTEIN ELK-1.
