In order to evaluate the composition and seasonal variations of the epilithic diatoms in Yedikır Dam Lake were studied using samples collected from the stones in the barrier area between November 2004 and April 2006. The diatom communities were diverse; 88 taxa were found, belonging to the Bacillariophyta. Cymbella minuta, Cyclotella ocellata and Encyonema silesiacum have become the most abunda...

OBJECTIVE To investigate the effect of material deprivation on the winter rise in mortality and temperature dependent variations in mortality. DESIGN Ecological comparison of seasonal mortality at electoral ward level. Main outcome measures were ratios of winter to rest of the year mortality rates (seasonality ratios) and monthly deaths as the outcome variable in a model with monthly average ...

Although physical limitations associated with transfemoral amputation (TFA) have been studied in laboratory settings, little is known about habitual activity within free-living environments. A retrospective analysis of 12 mo of step activity data was performed to quantify activity levels, variations, and patterns in 17 adults with unilateral TFA. Yearly, seasonal, and monthly average daily step...

OBJECTIVES Seasonal variations in ultraviolet B (UVB) radiation cause seasonal variations in vitamin D status. This may influence immune responses and play a role in the seasonality of influenza. METHODS Pandemic and non-pandemic influenzas in Sweden, Norway, the USA, Singapore, and Japan were studied. Weekly/monthly influenza incidence and death rates were evaluated in view of monthly UVB fl...

Albedo/reflectance is of great importance for glaciers’ mass balance and energy budget. Elevation could be a major factor of influence for glacier reflectance, and therefore when studying glacier reflectance, the altitude ranges should be considered. However, due to the limitations of traditional earth observation systems, conventional analyses usually consider the spatial and temporal patterns...

The accurate assessment of spatiotemporal rainfall variability is a crucial and challenging task in many hydrological applications, mainly due to the lack of a sufficient number of rain gauges. The purpose of the present study is to investigate the spatiotemporal variations of annual and monthly rainfall over Fujian province in China by combining the Bayesian maximum entropy (BME) method and sa...

The GRACE large-scale sequent GRACE-FO gravity satellite mission is providing monthly field solutions for almost 20 years enabling a unique opportunity to monitor mass variation processes. anomaly time series the Aral Sea region has been derived period of April 2002 January 2022. method determining from and improved by taking into account variations Caspian Sea. then compared estimates. For der...

Many of us have been watching the Olympics this week (how about that Phelps?). The first week culminated with an exciting individual women’s gymnastics competition. Despite the home advantage (see Balmer and Nevill, 2003 in the annotated bibliography), Americans Nastia Liukin and Shawn Johnson took Gold and Silver respectively (63.325 and 62.725), with Chinese Yilin Yang winning Bronze (62.650)...
