January 2022States of Matter: Gases, Liquids, Plasmas, and Solids, Third Edition
by Krista West
Praise for the previous edition: "...aided by clear diagrams and photographs, as well as sidebars that cover historical background, notable scientists, and practical applications of the chemistry concepts."—The Horn Book Guide Without the different states of matter—the solids, liquids, gases, and plasmas that make up our universe—the world would be a very boring place. States of matter are constantly changing form all around us: hot showers steam up the bathroom mirror, gaseous water falls to the ground as snow, liquid escapes from our skin to cool the body, and plasma moves from the atmosphere to the surface of the Earth via lightning strikes. But, as readers of this insightful eBook will learn, these things don't happen by accident. States of Matter: Gases, Liquids, Solids, and Plasmas, Third Edition deciphers the science behind these chemical states to present an engaging and eye-opening reference enhanced by full-color photographs and illustrations.

Science & MathematicsMay 2020Optical Manipulation of Pests and Beneficial Arthropods
by David Ben-Yakir, Antoine Abrieux, Joanna C. Chiu, Joseph E. Funderbunk, Daphna Gottlieb, Gábor Horváth, Simcha Lev-Yadun, Un Taek Lim, Xavier Martini, Masami Shimoda, Robert van Tol
Arthropod pests, pollinators, and natural enemies of pests have a great economic importance to human health and food supply worldwide. Arthropods use optical cues to find food and suitable oviposition sites, daily and seasonal activities, orientation and navigation. Most arthropods have compound eyes with receptors for UV light (peak sensitivity at 360 nm) and for green-yellow light (peak sensitivity at 520-540 nm). Many arthropods also have simple eyes (ocelli) that respond to changes in light intensity. Some arthropods can detect linearly polarized light and use it as an optical cue for oviposition sites, finding of hosts and navigation.The properties of the optical cue, such as wavelength, intensity, polarization, size, shape and contrast, greatly affect their response to the optical cue. Therefore, manipulation of optical cues can interfere or enhance arthropods' activities and development. UV light has been used to attract insects for monitoring and control. The patterns of UV reflected from flowers and plants affect arthropods' preference to visit them. The absence of UV light often deters arthropods and decreases their dispersal rate. UVB induces general stress in plants which may increase their resistance to arthropod pests. Green-yellow color induces landing and favors settling (arresting) of many plant feeding arthropods. High levels of reflected sunlight (above 25% of sun radiation) deters arthropods' landing and reduces settling. The recent use of monochromatic lights to increase crop yield, or to induce desirable plant characteristics, is expected to affect the activity of the associated arthropds as well. Optical manipulations are proposed as a part of an integrated pest management (IPM) program for open-field and protected crops, and for protecting the health of humans and domestic animals. This book contains up-to-date reviews of the published literature, some unpublished results of the authors, and suggestions for future research and development of this method.

May 2022Feline Reproduction
by Aime Johnson, Michelle Kutzler
Cats are one of the most popular pets in the world, and as homes become smaller, and single-person households become more common, it is predicted that the numbers being bred and kept will only grow. In Feline Reproduction, the global author team cover all aspects of reproduction in the queen and the tom. Beginning with basic anatomy and normal reproduction, it goes on to cover practical knowledge about pregnancy, neonatal care, breeding soundness exams, and semen cryopreservation. It also includes an overview of factors, diseases, and abnormal conditions affecting reproduction, such as infertility, causes of abortion and contraception. Covering both pet patients and nondomestic species, this book provides a thorough grounding in feline reproduction for the general veterinary practitioner, veterinary student, animal scientist, and experienced cat breeder.

Animal husbandryMay 2004Encyclopedia of Farm Animal Nutrition
by N J Benevenga, Santosh P Lall, Kelvin J McCracken, Hussain M Omed, Roger F E Axford. Edited by Malcolm F Fuller.
The Encyclopedia of Farm Animal Nutrition deals with the whole of farm animal nutrition, embracing a wide range of disciplines, including physiology, biochemistry, veterinary medicine and feed technology.The encyclopedia contains approximately 2000 entries from 90 contributors. These entries range from short definitions to more discursive articles, all entries are fully cross-referenced to aid further research.The encyclopedia covers every type of farm animal found in both developing and developed countries, including cattle, sheep, pigs, chickens, goats, horses, fish, deer, buffaloes, rabbits and camelids, as well as ducks, turkeys, ostriches and other birds.Sample Entries: Acylglycerol, A form of lipid made up of one glycerol molecule combined with three individual (not necessarily identical) fatty acid molecules attached to the glycerol by ester bonds. Acylglycerols form part of the neutral lipid fraction.Free fatty acids (FFAs), Also called non-esterified fatty acids (NEFAs), fatty acids that are not esterified to glycerol or another alcohol such as choline or cholesterol. In blood plasma or serum, FFAs are really not free but bound to plasma albumin.Locust bean, Properly the fruit of the African locust bean tree (Parkia filicoidea) but the name is frequently applied to the fruit of the carob tree (Ceratonia siliqua). The latter originated in the eastern Mediterranean region and is also found in the subtropics. The fruits are thick, fleshy (more so in the carob) pods each containing about a dozen seeds. The seeds are tough and must be crushed before feeding. The resulting meal has a high sugar and energy content and is very palatable but is low in protein (42-54 g kg-1).Oyster Shell, Oyster shells are almost pure calcium carbonate (95-99%) and are good sources of calcium for all classes of animals. Clam shells, conch shells, coral and coral sand can all be used for feeding. Shells that have been ground to coarse grit tend to be more palatable to laying hens and help grain digestion in the gizzard, as well as producing strong eggshells. For laying hens the shells should be ground to 0.5-2.0 mm and mixed 2:1 with finely ground limestone.Pacu, A commercially important freshwater fish native to the rivers of Brazil. This large migratory fish reaches 60 cm in length and is a scavenger that eats vegetation, mostly of fruit that falls into the water as well as an occasional small fish or insect. Pacu is one of the first native fish species to be successfully cultured in Brazil. A market size of 1-2 kg can be attained in 18-20 month at water temperatures of 22-280 C.

January 2021Cell Structure, Processes, and Reproduction, Third Edition
by Kristi Lew and Phill Jones
Cells are considered one of the most basic units of life, yet their structure, processes, and reproduction are intricate and complex. From plasma membranes to cell organelles to the macromolecules that are the brick and mortar of a cell, structure is an important aspect to maintain the life processes of a cell. Some of these processes, including transfer of information from DNA to RNA to protein and the control of gene expressions, are necessary functions that aid in cell reproduction. In Cell Structure, Processes, and Reproduction, Third Edition, readers will explore how the major characteristics of a cell are crucial in enabling these tiny units to carry out specialized functions in multicellular and single-celled organisms.
