Development of a RIVPACS-type predictive model for bioassessment of wadeable streams in Wyoming

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Concepts and Approaches for the Bioassessment of Non-wadeable Streams and Rivers

Concepts and Approaches for the Bioassessment of Non-wadeable Streams and Rivers - Chapter 8

Assessment data are collected not only to help define the status of large rivers, but also to guide management decisions. Data must be translated into a format from which management decisions regarding water resources can be made. The strategies outlined in Chapters 2 and 3 on the elements of assessment and study design, provide users with approaches to clearly define questions and objectives t...

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

Development of a new toxic-unit model for the bioassessment of metals in streams.

Two toxic-unit models that estimate the toxicity of trace-metal mixtures to benthic communities were compared. The chronic criterion accumulation ratio (CCAR), a modification of biotic ligand model (BLM) outputs for use as a toxic-unit model, accounts for the modifying and competitive influences of major cations (Ca²(+), Mg²(+), Na(+), K(+), H(+)), anions (HCO₃⁻, CO²⁻₃ ,SO²⁻₄, Cl⁻, S²⁻) and dis...
