Standard Guideline for the Geostatistical Estimation and Block-Averaging of Homogeneous and Isotropic Saturated Hydraulic Conductivity (ASCE/EWRI 54-10) is the third standard in a series that enhances the probabilistic characterization and understanding of the behavior of a key groundwater parameter, the saturated hydraulic conductivity. The geostatistical estimation and block-averaging of the saturated hydraulic conductivity find many applications in applied groundwater hydrology. Among these, the most noteworthy are the characterization of the spatial distribution of saturated hydraulic conductivity and the specification of averaged values of saturated hydraulic conductivity over volumes of aquifer (or blocks) for the purpose of groundwater flow model calibration. The geostatistical approach takes advantage of this spatial statistical structure, providing relatively simple results, and makes it easy to implement in the field when required conditions are met. This standard will be useful to environmental engineers, water resources engineers, and anyone who uses hydraulics in engineering.

Solid matter. Monolithic and homogeneous concepts for a circular approach to architecture. In response to climate change, architects have been seeking a contemporary expression for durable, solid and homogeneous wall structures made of clay, wood, brick, concrete and recycled materials. This book follows 25 projects to analyze construction methods that predominantly involve materials that have a single origin and can be easily dismantled. It looks at a variety of different ways and scales in which architects have dealt with issues of mass and materiality, both in terms of design and construction. Structured according to the specific materials, the book allows direct comparisons, and renders visible solid building typologies and forms. Numerous drawings, developed especially for this book, document the projects. Two essays as well as interviews with Pepe Marquez and Arno Richter examine the strategies and background of monolithic architecture and solid construction methods.

Since the Second World War, congressional parties have been characterized as declining in strength and influence. Research has generally attributed this decline to policy conflicts within parties, to growing electoral independence of members, and to the impact of the congressional reforms of the 1970's. Yet the 1980's witnessed a strong resurgence of parties and party leadership-especially in the House of Representatives. Offering a concise and compelling explanation of the causes of this resurgence, David W. Rohde argues that a realignment of electoral forces led to a reduction of sectional divisions within the parties-particularly between the northern and southern Democrats-and to increased divergence between the parties on many important issues. He challenges previous findings by asserting that congressional reform contributed to, rather than restrained, the increase of partisanship. Among the Democrats, reforms siphoned power away from conservative and autocratic committee chairs and put control of those committees in the hands of Democratic committee caucuses, strengthening party leaders and making both party and committee leaders responsible to rank-and-file Democrats. Electoral changes increased the homogeneity of House Democrats while institutional reforms reduced the influence of dissident members on a consensus in the majority party. Rohde's accessible analysis provides a detailed discussion of the goals of the congressional reformers, the increased consensus among Democrats and its reinforcement by their caucus, the Democratic leadership's use of expanded powers to shape the legislative agenda, and the responses of House Republicans. He also addresses the changes in the relationship between the House majority and the president during the Carter and Reagan administrations and analyzes the legislative consequences of the partisan resurgence. A readable, systematic synthesis of the many complex factors that fueled the recent resurgence of partisanship, Parties and Leaders in the Postreform House is ideal for course use.

The effective and efficient application of PPP in agriculture is a very complex task, involving a lot of aspects ranging from active substance properties to climatic conditions, from target structure to equipment features, from operator awareness to the reference legislative framework. Some of these aspects have been treated in the six papers collected in this Special Issue on “Pesticide Applications in Agricultural Systems”.

Technology: general issues --- nozzle testing apparatus --- pesticide --- drop pulverization --- drop size distribution --- image analysis --- pesticide application --- pneumatic nozzle --- homogeneity --- airflow speed --- liquid flow rate --- spray drift reducing --- spray quality --- inhalation exposure --- dermal exposure --- stretcher-type power sprayers --- orchards --- fixed spray delivery --- SSCDS --- spray drift --- deposition --- coverage --- Aedes aegypti --- Leucauge argyrobapta --- nontarget effects --- permethrin --- pyrethroid --- Tetragnathidae --- greenhouse --- precision spraying --- rover --- environment protection --- operator’s health --- consumer’s safety --- n/a --- operator's health --- consumer's safety
