Epilithic chironomid larvae and water enrichment: is larval distribution explained by epilithon quantity or quality?

Global stressors on water quality and quantity.

This inequality is especially critical for Asia, which has 60% of the world’s population but only 36% of the world’s water. Water quality in terms of pollutant loading also is not distributed equally and is related to the type of use and a country’s level of development (Figure 2). Developing countries often have less capacity to improve water quality and depend on lower-quality water for a var...

A Meta-model for Water Quantity and Water Quality

The management of water resources requires simulation models for different time horizons and spatial scales as well as different types of information systems as GIS or Water Information Systems. Mathematical models integrate former experiences and theoretical knowledge about a system with actual information gained by natural processes and man-induced activities. Because of the great variety and...

Culex restuans (Diptera: Culicidae) oviposition behavior determined by larval habitat quality and quantity in southeastern Michigan.

Oviposition is a critical stage in the mosquito lifecycle, and may determine population levels, distribution, biting behavior, and pathogen transmission. Knowledge of the oviposition behavior of Culex restuans Theobald has become particularly important with the emergence of West Nile virus (WNV) in North America. Laboratory and field studies have examined some factors that contribute to oviposi...

High density Lipoprotein; What to Measure: Quality or Quantity?

Quality of the Articles or Quantity of the Articles?

برای دانشجویان و دانشمندان جوان ممکن است این سؤال مطرح گردد که برای دانشمند شدن، کیفیت یا کمیت مقالات یک فرد است که دارای اهمیت می‌باشد؟ شخصاً، بارها با این سؤال به هنگام برگزاری کارگاه‌های مقاله نویسی مواجه شد‌ه‌ام. Salthammer در انتهای سخن سردبیری خود، دو مثال بسیار جالب می‌آورد تا به روشنی به سؤال فوق پاسخ دهد. او در ابتدا به شیمیدان روسی به نام Yuri Struchkov اشاره می‌کند که در سال 1926 میل...
