Abstract Laser-induced time-resolved luminescence was used to study rare earth element (REE) containing natural apatite and calcite minerals. The from 400 nm 700 nm in the minerals analyzed with excitation ranges 210–340 nm 405–535 nm. As an outcome, several useful wavelengths detect one or more REE are reported. feasibility of selected excitations e.g. avoiding disturbance intense Mn2+ band, r...

Frequency control can be considered to be one of the most crucial aspects of ancillary services. This paper revises the current basics of calculating the factors used in these control schemes, showing limitations of these, thus highlighting the need for new sizing methods. The basis for implementing these is presented, along with an explanation why it is not desirable to implement completely ne...

from England and Wales report physical and sexual assault by a current or former partner; when financial and emotional abuse and threats of abuse are included, this increases to 25% of women. Two women are murdered by their partner or ex-partner every week in England and Wales and similar figures are reported internationally. One in seven men in the UK also report experiencing physical assault ...

In this work, in an plant were investigated order propose system improve the keep productivity. The was se...

OBJECTIVE Both poor marital quality and sleep disturbances are risk factors for a broad range of mental and physical health morbidities. The purpose of the study was to investigate bidirectional relationships between marital quality and sleep disturbance and the moderating effects of age and gender. METHODS Data from 1081 married individuals who participated in the Korean Genome and Epidemiol...

We investigate the asymptotic behavior of the OLS residual{based CUSUM test for parameter constancy in a dynamic regression with heavy{tailed disturbances. We extend previous results by relaxing the nite{variance assumption and consider disturbances in the domain of attraction of a stable Paretian law. The main result is a functional limit theorem for the self{normalizing CUSUMs of OLS residual...

Introduction There are approximately 750,000 people in the UK with dementia with many being cared for in a nursing home environment. Dementia patients often exhibit significant mental state disturbances including confusion, agitation and aggression and these may be provoked or exacerbated by many external factors. In this study we hypothesised that optimising the sensory awareness of residents ...

The impact of family and child rearing practices on personality development and psychiatric illnesses are well established. The present investigation is directed towards the study of psychopathology and temperamental characteristics of children of alcoholic parents, to find out correlation between these two areas and the role of alcoholism in child rearing practices. A group of 100 children of ...

The disturbances of memory immediately following electric convulsion therapy (E.C.T.) have been the subject of many investigations (Zubin and Barrera, 1941; Mayer-Gross, 1943; Liberson and Wilcox, 1945; Kalinowsky and Hoch, 1947). Implicit, ifnot explicit, in the majority of these papers is the assumption that memory can be studied in isolation, Bartlett, however, (1932), long ago demonstrated ...

Although people who experience happiness tend to have better psychological health, people who value happiness to an extreme tend to have worse psychological health, including more depression. We propose that the extreme valuing of happiness may be a general risk factor for mood disturbances, both depressive and manic. To test this hypothesis, we examined the relationship between the extreme val...
