Hele-Shaw clutch: The Hele-Shaw clutch was an early form of multi-plate wet clutch, in use around 1900. It was named after its inventor, Professor Henry Selby Hele-Shaw, who was noted for his work in viscosity and flows through small gaps between parallel plates.Nest (protein structural motif): The Nest is a type of protein structural motif. Peptide nests are small anion-binding molecular features of proteins and peptides.Reproductive toxicity: Reproductive toxicity is a hazard associated with some chemical substances, that they will interfere in some way with normal reproduction; such substances are called reprotoxic. It includes adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring.Silence of the Songbirds: Silence of the Songbirds (ISBN 978-0-8027-1609-5) is a book by bird lover and scientist Bridget Stutchbury about the rapid decline and loss of many species of songbirds. Some major threats covered include pesticides, sun-grown coffee, city lights, cowbirds, and global warming.Skylark launch tower: A Skylark tower is a tower used for the launch of earlier versions of Skylark rockets. As Skylark rockets have no guidance system and accelerate slowly, they require a safe launch tower with a height of at least 24 metres with a guidance system.Kittiwake: The kittiwakes (genus Rissa) are two closely related seabird species in the gull family Laridae, the black-legged kittiwake (R. tridactyla) and the red-legged kittiwake (R.Wet-tailSexual motivation and hormones: Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability to engage in sexual behaviours.Tokay gecko: The tokay gecko (Gekko gecko) is a nocturnal arboreal gecko, ranging from northeast India, Bhutan, Nepal, Bangladesh, throughout Southeast Asia, Philippines to Indonesia and western New Guinea. Its native habitat is rainforest trees and cliffs, and it also frequently adapts to rural human habitations, roaming walls and ceilings at night in search of insect prey.Sarah R, Lotfi: Sarah R. Lotfi (b.Constriction: Constriction is a method used by various snake species to kill their prey. Although some species of venomous and mildly venomous snakes do use constriction to subdue their prey, most snakes which use constriction lack venom.Bird trapping: Bird trapping techniques to capture wild birds include a wide range of techniques that have their origins in the hunting of birds for food. While hunting for food does not require birds to be caught alive, some trapping techniques capture birds without harming them and are of use in ornithology research.Restricted isometry property: In linear algebra, the restricted isometry property characterizes matrices which are nearly orthonormal, at least when operating on sparse vectors. The concept was introduced by Emmanuel Candès and Terence TaoE.Immunoglobulin Y: Immunoglobulin Y (abbreviated as IgY) is a type of immunoglobulin which is the major antibody in bird, reptile, and lungfish blood. It is also found in high concentrations in chicken egg yolk.Deep litter: Deep litter is an animal housing system, based on the repeated spreading of straw or sawdust material in indoor booths. An initial layer of litter is spread for the animals to use for bedding material and to defecate in, and as the litter is soiled, new layers of litter are continuously added by the farmer.Polistes dominula: The European paper wasp (Polistes dominula, often misspelled as dominulus) is one of the more common and well-known species of social wasps in the genus Polistes. Its diet is more diverse than that of most Polistes species (many genera of insects versus mainly caterpillars in other Polistes), making it superior over many others during the shortage of resources.Victor Willard: Victor M. Willard (1813 – December 10, 1869) was an American farmer from Waterford, Wisconsin who spent two years (1849–1850) as a Free Soil Party member of the Wisconsin State Senate from the 17th District.Parasitic disease: A parasitic disease is an infectious disease caused or transmitted by a parasite. Many parasites do not cause diseases.Plant breedingIntraguild predation: Intraguild predation, or IGP, is the killing and eating of potential competitors. This interaction represents a combination of predation and competition, because both species rely on the same prey resources and also benefit from preying upon one another.Eggshell: An eggshell is the outer covering of a hard-shelled egg and of some forms of eggs with soft outer coats. Bird eggshells contain calcium carbonate and dissolve in various acids, including the vinegar used in cooking.Immunocompetence: Immunocompetence is the ability of the body to produce a normal immune response following exposure to an antigen. Immunocompetence is the opposite of immunodeficiency or immuno-incompetent or immuno-compromised.Utiaritichthys: Utiaritichthys is a genus of serrasalmid found in the Amazon and Orinoco basins in tropical South America.Behavior-altering parasites and parasitoids: Some parasites and parasitoids cause changes in the behavior of their hosts by directly affecting the hosts' decision-making and behavior control mechanisms. The acquired or modified behaviors assist in parasite transmission, and often result in the host's demise.Marcos Paz, Buenos AiresFour Seasons Baltimore and Residences: Four Seasons Hotel Baltimore is currently a 22 story highrise hotel complex building which opened on November 14, 2011. The building's construction began back in 2007 and went through several changes.Hadrosaur diet: Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores. The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.Threshold host density: Threshold host density (NT), in the context of wildlife disease ecology, refers to the concentration of a population of a particular organism as it relates to disease. Specifically, the threshold host density (NT) of a species refers to the minimum concentration of individuals necessary to sustain a given disease within a population.Low Fertility Cohorts Study: The Low Fertility Cohorts Study, 1978: A Survey of White, Ever-Married Women Belonging to the 1901-1910 United States Birth Cohorts,Data Sharing For Demographic Research consists of personal interviews of white, ever-married women born between July 1, 1900, and June 30, 1910. In 1978, a national survey of 1,049 married women between the ages of 68 and 78 were interviewed between the months of March and July in order to investigate low fertility during the 1920s and 1930s and the women of childbearing age during those decades.Evolution in Variable EnvironmentHealth geography: Health geography is the application of geographical information, perspectives, and methods to the study of health, disease, and health care.
