Water is a finite resource that must be shared among multiple users and economic and conservation objectives can often be seen as being in conflict. We explored this perception by conducting an integrated bioeconomic analysis of irrigated agriculture and the conservation of freshwater attributes in an agricultural landscape, the Tasmanian Midlands. We constructed a simple bioeconomic model base...

Climate change, water supply limits, and continued population growth have intensified the search for measures to conserve water in irrigated agriculture, the world's largest water user. Policy measures that encourage adoption of water-conserving irrigation technologies are widely believed to make more water available for cities and the environment. However, little integrated analysis has been c...

The reproductive behavior and the seasonal occurrence of Psecas viridipurpureus were studied at the Estação Ecológica do Noroeste Paulista, a small conservation area in the northwest region of São Paulo State, Brazil (49 degrees 22'50"W and 20 degrees 48'36"S). P. viridipurpureus occurred on "gravatá", a bromeliaceous plant (Bromelia balansae, Bromeliaceae) which does not accumulate rain water....

The purpose of this investigation is to describe changes in industrial injury and disease rates in British Columbia between 1950 and 1996. Data on injury and disease rates were abstracted manually from WCB Annual Reports for the years 1950 through 1996. A number of interesting patterns emerge. Death report rates declined by 79% during the study period. Injury report rates also declined, althoug...

A method is presented to use a dimensionless form of the well-known Niyama criterion to directly predict the amount of shrinkage porosity that forms during solidification of metal alloy castings. The main advancement offered by this method is that it avoids the need to know the threshold Niyama value below which shrinkage porosity forms; such threshold values are generally unknown and alloy dep...

The Conservation Effects Assessment Project was established to quantify water quality benefits of conservation practices supported by the U.S. Department of Agriculture (USDA). In 2004, watershed assessment studies were begun in fourteen agricultural watersheds with varying cropping systems, landscapes, climate, and water quality concerns. This paper reviews USDA Agricultural Research Service '...

Changes in precipitation can influence soil water and nutrient availability, and thus affect plant nutrient conservation strategies. Better understanding of how nutrient conservation changes with variations in water availability is crucial for predicting the potential influence of global climate change on plant nutrient-use strategy. Here, green-leaf nitrogen (N) and phosphorus (P) concentratio...

Extreme wind speeds, gusts, and wave heights associated with midlatitude cyclones pose a hazard to shipping lanes offshore infrastructure operating in the North Atlantic Ocean seas surrounding British Isles. Several studies have assessed variability of waves this region using reanalyses, but few used surface observations extreme speeds heights. Here, we use network marine stations derive 2012–2...

Over the last 12 years, Wales Cancer Biobank (WCB) has consented to more than 2000 patients with colorectal cancer (CRC). From these patients, clinical data been collected and have followed through their journey. Clinical from analyzed identify any correlation between disease grade outcome. In a small cohort, consisting of 407 WCB performed genetic analysis on patient primary tumor samples, ide...

Water conservation is a priority in San Antonio, Austin, Dallas, and other major Texas cities that routinely face water shortages and drought. Soil management is fundamental to water conservation efforts. Incorporation of composted biosolids (CB) in low quality soils can enhance water conservation and provide organic carbon and nutrients that improve growth of vegetation and limit sediment loss...
