The seasonal autoregressive moving average SARMA models have been widely adopted for modeling many time series encountered in economic, hydrology, meteorological, and environmental studies which exhibited strong seasonal behavior with a period s. If the model is adequate, the autocorrelations in the errors at the seasonal and the nonseasonal lags will be zero. Despite the popularity uses of the...
Objective Previous studies, although inconclusive, have suggested possible associations of environmental risk factors with the development of giant cell arteritis (GCA). We aim to investigate seasonal influence on the incidence of GCA across Australia and New Zealand. Methods In establishing an international study to investigate the molecular aetiology of GCA, archived temporal artery biopsy ...
PURPOSE Fungi are a major cause of keratitis, although few medications are licensed for their treatment. The aim of this study is to observe the variation in commercialisation of antifungal eye drops, and to predict the seasonal distribution of fungal keratitis in Brazil. METHODS Data from a retrospective study of antifungal eye drops sales from the only pharmaceutical ophthalmologic laborato...
Introduction: Mosquito – borne diseases are a major public health threat in the world, including Iran. This investigation was undertaken to determine fauna, distribution, frequency and monthly activity of Anopheles larvae in Aligoudarz County. Methods: This descriptive research was carried out during April to December 1997 to study Anopheles mosquitoes fauna and seasonal activity in seven...
Recently, in the Auerswald et al. (2015) comment on "Rainfall erosivity in Europe", 5 criticisms were addressed: i) the neglect of seasonal erosion indices, ii) the neglect of published studies and data, iii) the low temporal resolution of the data, especially of the maximum rain intensity, iv) the use of precipitation data instead of rain data and the subsequent deviation of the R-factor in Ge...
Reproductive success usually declines in the course of the season, which may be a direct effect of breeding time, an effect of quality (individuals with high phenotypic or environmental quality breeding early), or a combination of the two. Being able to distinguish between these possibilities is crucial when trying to understand individual variation in annual routines, for instance when to bree...
As we start a new school year I would like to take this opportunity to welcome back the many students, staff, research associates and faculty associated with the Center for the Integrative Study of Animal Behavior (CISAB). To those of you who are new to CISAB and the Indiana University community, I would like to extend a special welcome to you and I would also like to express my excitement abou...
BACKGROUND: Climatic or meteorological condition changes have been implicated in the pathogenesis of Idiopathic Sudden Sensorineural Hearing Loss (ISSHL). We investigated the seasonal distribution of ISSHL and evaluated the influence of meteorological parameters (such as temperature, humidity, and atmospheric pressure), their variation and covariation on the incidence of the disease. METHODS: A...
During a survey of Gahar Lake and Gahar River from 2008 to 2009 some specimen obtained by seasonal sampling in 6 stations, 3 stations in the lake and 3 stations in the river. Three different methods were used for sampling, gill net and hook in the lake and electrofishing in the river. Due to the results 3 species from 2 families in Gahar Lake and 12 species form 3 families in Gahar River were...
Background and purpose: Bacterial and fungal bioaerosols play important roles in the atmosphere and have significant effects on human health. This study aimed at investigating the concentration of bioaerosols in ambient air in Shahrekord, Iran during two warm and cold seasons at three different points in 2019. Moreover, the effect of meteorological factors such as temperature, relative humidit...
