Abstract

Hoverflies of the Northwest Europe is an updated edition with revisions to the text. It identifies the hoverflies of Northwest Europe and incorporates the knowledge that has been published in many articles over the past decades. The book covers 500 species - nearly two thirds of the known European syrphid fauna. The main body of the book consists of dichotomous keys to all the hoverfly species found in the region, richly illustrated with drawings that show details as well as whole flies. • What are hoverflies and how are they to distinguish from bees, wasps and other bees • Where are they found? (forests, woodlands, marshes, peatlands and bogs, meadows, grasslands, gardens • When is the best time to find and see hoverflies? • Collecting and preservering specimens • Early stages (eggs and larvae) • How to use this book? • The hoverfly body • Identification keys to the genera and 500 species of Northwest Europe • richly illustrated with drawings that show details as well as whole flies

Abstract

Britain's Hoverflies is a beautifully illustrated photographic field guide to the hoverflies of Britain, focusing on the species that can be most readily identified. It is the perfect companion for wildlife enthusiasts, professional ecologists and anyone else with an interest in this fascinating group of insects, and is designed to appeal to beginners and experts alike. Accessible, authoritative and easy to use, this book contains hundreds of remarkable photographs of the various life stages of those species that can be identified by eye or with a magnifying glass, with coverage of at least one representative from each of the British genera. It also features an essential guide to the hoverfly tribes. Detailed species accounts summarize the species' status, highlight the key identification features, provide notes on behaviour and habitat requirements and include flight-period charts and up-to-date distribution maps. Sections on hoverfly biology, where and when to look for hoverflies, legislation and conservation, photographing hoverflies, recording hoverflies and gardening for hoverflies are also included. This fully revised and updated second edition: Features more than 650 stunning colour photographs Provides detailed information for the 167 species that can be most readily identified, including at least one species from each of the 68 genera recorded in Britain Includes a complete list of the 283 hoverfly species recorded in Britain to date, with an indication of how difficult each is to identify

Abstract

The demand for computational fluid dynamics (CFD)-based numerical techniques is increasing rapidly with the development of the computing power system. These advanced CFD techniques are applicable to various issues in the industrial engineering fields and especially contribute to the design of fluid machinery and fluid devices, which have very complicated unsteady flow phenomena and physics. In other words, to aid the rapid development of CFD techniques, the performances of fluid machinery and fluid devices with complicated unsteady flows have been enhanced significantly. In addition, many persistently troublesome problems of fluid machinery and fluid devices such as flow instability, rotor–stator interaction, surging, cavitation, vibration, and noise are solved clearly using advanced CFD techniques.This Special Issue on “CFD-Based Research and Applications for Fluid Machinery and Fluid Devices” aims to present recent novel research trends based on advanced CFD techniques for fluid machinery and fluid devices. The following topics, among others, are included in this issue:- CFD techniques and applications in fluid machinery and fluid devices;- Unsteady and transient phenomena in fluid machinery and fluid devices;- Pumps, fans, compressors, hydraulic turbines, pump turbines, valves, etc.
