this study investigated the effects of sewage discharge on nutrient concentrations and bod5 levels in the coastal waters and sediments ofthe city of mombasa. the results indicated that nutrient concentrations in tudor, mtwapa and makupa creeks were elevated as compared to concentrations in gazi creek (mean ranges of 0.022-0.039mg/l, 0.038-0.163mg/l and 0.034-0.118mg/lphosphates, nitrates and am...

Continuous discharge from a combined sewer overflow (CSO) into a tidal wetland creek in the New York City urban area was analyzed to assess the extent of water quality degradation during both dry and wet weather. A combination of fecal indicator bacteria (FIB), total suspended solids, and dissolved metals were used to infer the presence of sewage and fecal pollution from the CSO discharge and t...

The Goshen Swamp, a fourth order blackwater creek in southeastern North Carolina, was clearcut of 130 acres of riparian and seasonally flooded forest in late May through September 1998. Downstream water quality had been monitored monthly for 212 years before the clearcut, during the clearcut, and for two years following the clearcut. The objective of this paper was to test the hypothesis that c...

each stream ecosystem may be impacted by land use and intensified human expansion. According to the fall macrobenthic results, nearly all sites saw an increase in %EPT, except for Massaponax 208 and Ni Route 1. Even though both Massaponax Creek and the Ni River are under EPA legal limits for phosphate and nitrate concentrations, the phosphate levels usually rose in summer on the Massaponax and ...

Glacial deposits in the southwestern Ahklun Mountains, southwestern Alaska, record two major glacier advances during the late Pleistocene. The Arolik Lake and Klak Creek glaciations took place during the early and late Wisconsin, respectively. During the Arolik Lake glaciation, outlet glaciers emanated from an ice cap centered over the central portion of the Ahklun Mountains and expanded beyond...

In order for the Bureau of Land Management (BLM) to comply with the Government Performance and Results Act (GPRA), and better meet the needs of the public; a visitor satisfaction survey was conducted at 23 BLM recreation sites in 11 states during fiscal year 2010 (FY10). The survey was developed to measure each site's performance related to BLM GPRA Goal 3.1 Provide for a quality recreation exp...

Redband trout (Oncorhynchus mykiss ssp.) in southeastern Oregon inhabit high-elevation streams that exhibit extreme variability in seasonal flow and diel water temperature. Given the strong influence and potential limitations exerted by temperature on fish physiology, we were interested in how acute temperature change and thermal history influenced the physiological capabilities and biochemical...

BACKGROUND Participation and performance trends have been investigated in ultramarathons and ultratriathlons but not in ultracycling. The aim of the present study was to investigate (1) participation and performance trends in ultraendurance cyclists, (2) changes in cycling speed over the years, and (3) the age of the fastest male and female ultraendurance cyclists. METHODS Participation and p...
