Zustand: Very Good. 203, text figs. 295x210mm. PB. Vg. Proceedings of a British Ecological Society Symposium, September 1995, York. This symposium was the first on the genetic aspects of nature conservation to be held in Britain. The first section includes contributions that discuss both the theoretical and practical questions that conservationists should be asking when planning programmmes to conserve biodiversity. Later chapters attempt to answer these questions looking at a diverse range of British species. Sections: the conservation implications of genetic survey data; genetics and species recovery; conservation genetics and demography. [9781861074386].…

Taschenbuch. Zustand: Neu. Neuware - Roz is tired.After her harrowing encounter with The Shadow, slews of new ghost encounters are springing up around the city. So when a mysterious, deadly creature appears in the forest outside town, Roz knows it's up to her to deal with that, too. But when she tries, she gets far more than she'd bargained for, along with a whole new problem to solve. Now, a second Shadow has been following her, watching her from afar. When Roz and her friends try to end this battle before it starts, she learns that there is far more to these paranormal encounters than she ever could have imagined.…

Taschenbuch. Zustand: Neu. Neuware - MASTER RESIDENTIAL DUCT DESIGN, SIZING, AND AIRFLOW WITH CONFIDENCE>Residential Duct Systems Handbook is a practical field guide to understanding, designing, sizing, installing, evaluating, and troubleshooting residential duct systems. It takes you beyond isolated duct-sizing formulas and shows how the major parts of residential HVAC design work together. UNDERSTAND THE COMPLETE HVAC DESIGN PROCESSLearn how Manual J, Manual S, Manual D, and Manual T connect to form a complete residential HVAC design process. Understand how load calculations influence equipment selection, how equipment requirements determine airflow, how duct design delivers that airflow, and how registers and grilles distribute conditioned air throughout the home. INSIDE THIS HANDBOOK, YOU WILL LEARN HOW TO: - Understand airflow, CFM, velocity, pressure, friction, and resistance in residential duct systems- Connect Manual J, S, D, and T and understand how load, equipment, ducts, and air distribution depend on one another- Size supply and return ducts using practical design principles- Understand static pressure, friction rate, pressure losses, and system resistance- Account for fittings, transitions, elbows, branches, and equivalent resistance- Work with rigid and flexible ducts and understand installation practices that affect performance- Plan supply and return air distribution for more consistent comfort- Understand residential zoning and its effect on airflow and system performance- Apply practical methods for routing, supporting, sealing, insulating, and installing ductwork- Identify common causes of poor airflow, excessive noise, uneven temperatures, and high system resistance- Evaluate system performance and approach testing, balancing, and troubleshooting more systematicallyA PRACTICAL FIELD REFERENCE>From load requirements and equipment selection to duct sizing, airflow distribution, installation, and system performance, this book helps you see the complete picture and make better ductwork decisions.If you want to develop a stronger practical understanding of residential duct systems and the principles that make them perform properly, this handbook is built for you.…

Taschenbuch. Zustand: Neu. Neuware - Air conditioning work and commercial refrigeration share the same cycle, the same refrigerants and the same gauges. Everything else is different: the operating temperatures, the duty cycle, the controls standing between the thermostat and the compressor, the necessity of defrost, and the cost of being wrong. A comfort system that underperforms makes a building uncomfortable. A refrigeration system that underperforms destroys inventory overnight, quietly, while nobody is watching the box temperature. The system is also tightly coupled, which is what makes it hard. An undercharge and a restricted liquid line both read low on suction. Worn compressor valves and a fouled condenser both run hot. Reading one measurement in isolation produces confident, wrong conclusions. But because the effects propagate predictably, a small set of readings taken together forms a signature, and different faults produce different signatures.That is what this handbook teaches.- Read suction pressure, discharge pressure, superheat and subcooling as one coupled pattern, not four separate numbers- Predict what a healthy system should read under the current load and ambient, then measure against your prediction- Separate faults that share a symptom using compression ratio, condenser split and evaporator temperature difference- Set superheat on a zeotropic blend, where glide changes what the pressure is telling you- Trace a fault through a live ladder circuit, series safeties and parallel operating controls- Evacuate to a genuine vacuum, confirm it with a decay test, and charge by the method the system calls for- Calculate transmission, infiltration and product load, then reconcile it with what the system is actually doingSixteen chapters run from cycle thermodynamics and refrigerant properties through compressors, condensers, evaporators, metering devices, piping and oil return, electrical fundamentals, motors and drives, control circuits, defrost and safety controls, load calculation, service practice, systematic troubleshooting and commissioning. Each states its objectives, derives the theory step by step, and closes with worked examples and verified practice problems. Six appendices carry conversions, an equation reference, the field reading set, diagnostic quick-reference tables and blank service forms.>Open it at the troubleshooting chapter on your next call and work the reading set before you touch a component.…

Taschenbuch. Zustand: Neu. Neuware - Commercial and Industrial Wiring Handbook is a practical reference for understanding how commercial and industrial electrical systems are planned, installed, tested, maintained, and troubleshot in real working environments.Moving beyond basic wiring theory, this handbook connects electrical principles with the decisions electricians, technicians, engineers, inspectors, and maintenance professionals face on actual projects. It explains how power moves from the service entrance through distribution equipment, feeders, transformers, panelboards, branch circuits, motor systems, and specialized installations.Inside, you will learn how to: - Perform practical load calculations and apply demand factors for commercial and industrial installations.- Select conductors, cables, raceways, and protective devices based on system requirements and code considerations.- Understand overcurrent protection, voltage drop, grounding, bonding, and circuit protection.- Read single-line diagrams, schematics, panel schedules, wiring diagrams, and other common electrical documents.- Work with conduit systems including EMT, IMC, RMC, PVC, and cable tray applications.- Understand transformers, switchboards, panelboards, feeders, branch circuits, and power distribution systems.- Wire and troubleshoot motors, motor starters, contactors, overload protection, VFDs, and control circuits.- Apply grounding and bonding principles to improve electrical safety and system performance.- Understand testing and commissioning procedures used to verify electrical installations before they are placed into service.- Approach troubleshooting in a logical, practical way to locate faults and restore equipment safely.- Recognize important requirements for electrical work in commercial facilities, industrial plants, workshops, and other complex environments.- Build a stronger working understanding of electrical code requirements and how they affect installation decisions.Whether you are an apprentice developing practical skills, a journeyman electrician expanding into larger projects, a master electrician reviewing complex systems, an electrical engineer, inspector, maintenance technician, or student preparing for professional work, this handbook is designed to give you a clearer understanding of commercial and industrial wiring from planning to troubleshooting.With practical explanations, field-focused guidance, and a strong emphasis on safe and reliable installation, Commercial and Industrial Wiring Handbook is built to be a useful reference you can return to throughout your electrical career.…
