the microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. normally, microgrids contain renewable-energy-based distributed generation (dg) units, which their output power varies with different environmental conditions. in addition, load demand usually changes with factors such as hourly and seasonal customer activities. hence, these issues hav...

an analysis of seasonal rainfall over iran for a period of 30 years (1971-2000) shows a significant variability in spatial and temporal distributions of rainfall as well as its frequency and intensity. in this paper, the likely effects of enso on the rainfall anomalies are investigated. the accumulated monthly and seasonal rainfalls from 43 synoptic stations are taken through the islamic republ...

Seasonal distribution of the birth dates of 405 pre-menopausal and 285 post-menopausal breast cancer patients was investigated in order to determine whether or not the season of their birth was related to various reproductive risk factors of breast cancer, including nulliparity, late age at first birth, early age at menarche, late age at menopause, and a history of benign breast diseases. The s...

Chronic necrotizing skin ulcers caused by Mycobacterium ulcerans are a common and serious disorder in certain parts of the tropics. This infection was first described in Australia, but most of the reported cases have come from Uganda (where the disease is known as Buruli ulcer) and from the Congo. The disease is also known to occur in Nigeria, Ghana, Mexico, and New Guinea. The results of epide...

A review of 76 Southampton children with Henoch-Schönlein purpura has confirmed that there is no evidence of a streptococcal aetiology in the majority of cases of this disease. Among these patients the frequency of preceding respiratory infection of all kinds was only 7 percent greater than that in controls. Data on month of admission in four areas of England and Scotland show that the incidenc...

In ray Annual Reports to the London County Council I have published the results of an examination of the notified cases of scarlet fever and diphtheria in London, and which have led me to the conclusion that in these diseases there is seasonal variation both in fatality and age distribution. In the following Tables I give the results obtained from the use of the cases notified in the period 189...

The usefulness of time-series simulation of daily rainfall for estimating large quantiles of the distribution of 10 d seasonal maximum rainfall is questioned. The emphasis is on rare 10 d events having a mean recurrence time much longer than the length of the historical record. Time-series simulation uses nonparametric resampling. With a theoretical example assuming no temporal dependence, it i...

There is general consensus that season of birth influences the risk of developing psychiatric conditions later in life. We aimed to investigate whether the risk of schizophrenia (SC), bipolar affective disorder (BAD) and recurrent depressive disorder (RDD) is influenced by month of birth in England to a similar extent as other countries using the largest cohort of English patients collected to ...

The distribution of pelagic marine fishes and invertebrates varies seasonally. However, information on the seasonal variation of the distribution of most pelagic marine fishes and invertebrates is scarce. In this paper, seasonal changes in distribution ranges of commercially exploited pelagic fishes and invertebrates are predicted based on the existing Sea Around Us Project distribution, a pred...
