Results from the Finnish UKKI study on longitudinal changes in prevalences of different mental disorder categories in a population cohort (n=723) are presented. The subjects were investigated three times: in the original survey during 1969–71, and in two follow-ups (5 and 16 years after the original survey). The prevalence of all mental disorders was about(More)

Plasma concentrations of nitrazepam were measured by gas-liquid chromatography in: young healthy volunteers, in geriatric and psychiatric patients and in epileptic children. The disposition of nitrazepam was described in terms of a two-compartment open model. After a single oral dose of nitrazepam 5 mg the most prominent differences between the experimental(More)

The plasma diazepam, N-demethyldiazepam, and free oxazepam concentrations were studied in 12 neurotic outpatients during subchronic use, in 14 outpatients after chronic use, and in 8 test subjects after an acute intravenous administration. There are several reasons for believing that diazepam may induce its own metabolism in man: 1. The decrease in diazepam(More)
Psychiatric patients (N=26) were treated chronically (from 1 week to 12 years) with nitrazepam, because of insomnia. The patients gave their subjective estimations of the effects and side effects of nitrazepam. The concentrations of nitrazepam in the plasma were measured by 63Ni-EC-gas-liquid chromatography. The pharmacokinetics of nitrazepam were compared(More)
In order to obtain a higher spectral separation from the BPSK-like signals, i.e. GPS C/A code, the signals proposed for future Galileo and GPS M-code signals are processed using split-spectrum type modulations, such as Binary Offset Carrier (BOC) modulation. These BOC modulations create deep fades (ambiguities) in the envelope of the Autocorrelation(More)
Carrier aggregation transmissions in frequency division duplexing devices reduce the duplexing distance between the transmitter (TX) and receiver (RX) bands. As a consequence, the spurious intermodulation distortion products created by the nonlinear RF front-end of the TX may easily extend over to the RX band, potentially causing own RX desensitization. In(More)
In frequency division duplex transceivers employing non-contiguous carrier aggregation (CA) transmission, achieving sufficient isolation between transmit and receive chains using radio frequency filtering alone is increasingly difficult. Particularly challenging problem in this context is spurious intermodulation (IM) components due to nonlinear power(More)
This article addresses some implementation challenges in the potentially very energy-efficient charge-sampling radios. Alternative ways to implement charge sampler in charge sampling radio are considered, and the impacts and spectral shape characteristics of the sampling jitter induced signal distortion are analytically studied in these cases. The analysis(More)
