Both the conventional and the Carlson trophic state index (TSI) classification methods were employed to assess the eutrophication state of 26 lakes in the Norfolk Broads, UK. The parameters employed were: Secchi depth, chlorophyll a and total phosphorous which had been obtained previously by using Landsat TM imagery, ground reference data and empirical algorithms for the Norfolk Broads (Baban, ...

BACKGROUND The present study aimed to investigate the characteristics of occupational accidents and frequency and severity of work related accidents in the construction industry among Iranian insured workers during the years 20072011. METHODS The Iranian Social Security Organization (ISSO) accident database containing 21,864 cases between the years 2007-2011 was applied in this study. In the ...

Using thermometer-based air temperature records for the period 1850–2010, we present empirical evidence for a direct relationship between total solar irradiance (TSI) and the Equator-to-Pole (Arctic) surface temperature gradient (EPTG). Modulation of the EPTG by TSI is also shown to exist, in variable ways, for each of the four seasons. Interpretation of the positive relationship between the TS...

The purpose of the study was to compare muscle oxygenation as measured by two portable, wireless near-infrared spectroscopy (NIRS) devices under resting and dynamic conditions. A recently developed low-cost NIRS device (MOXY) was compared against an established PortaMon system that makes use of the spatially resolved spectroscopy algorithm. The influence of increasing external pressure on tissu...

BACKGROUND AND OBJECTIVE. There is a need for objective semiquantitative indexes for the evaluation of results of single-photon emission tomography (SPECT) in patients with brain glioma. The aim of this study was to validate the total size index (TSI) and total intensity index (TII) based on technetium-99m-methoxyisobutylisonitrile ((99m)Tc-MIBI) SPECT scans to discriminate the patients with hi...

Since November 1978 a set of total solar irradiance (TSI) measurements from space is available, yielding a time series of almost 30 years. Presently, there are three TSI composites available, called PMOD, ACRIM and IRMB, which are all constructed from the same original data, but use different procedures to correct for sensitivity changes. The PMOD composite is the only one which also corrects t...

Text-independent speaker recognition systems such as those based on Gaussian mixture models (GMMs) do not include time sequence information (TSI) within the model itself. The level of importance of TSI in speaker recognition is an interesting question and one addressed in this paper. Recent works has shown that the utilisation of higher-level information such as idiolect, pronunciation, and pro...

PURPOSE Graves ophthalmopathy and Graves disease may be caused by the same autoimmune process. An explanation for this may be the presence of autoantibodies reacting with an autoantigen in the orbit and the thyroid gland, like the thyroid-stimulating hormone (TSH) receptor. The purpose of this study was to see if initial levels of TSH receptor antibodies, known as thyroid-stimulating immunoglob...

PURPOSE To investigate associations between serum thyroid stimulating hormone (TSH) receptor antibody (TRAb) levels and Graves' orbitopathy (GO) activity/severity in chronic-stage GO and compare the performance of two newly-developed TRAb assays (third-generation TSH-binding inhibition immunoglobulin [TBII] assay versus Mc4 thyroid-stimulating immunoglobulin [TSI] bioassay). METHODS This stud...
