When the mosquito sucks blood the next time, it injects its saliva into the wound, and thus the virus reaches the blood of the bitten person.

When a female reproduces without such parasitic meals, she is said to practise autogenous reproduction, as in Toxorhynchites ; otherwise, the reproduction may be termed anautogenous, as occurs in mosquito species that serve as disease vectors, particularly Anopheles and some of the most important disease vectors in the genus Aedes.

When the mosquito first lands on a potential host, her mouthparts will be enclosed entirely in this sheath, and she will touch the tip of the labium to the skin in various places.

When the mosquito drinks a sugar solution, it is directed to a crop.

When a mosquito carrying dengue virus bites a person, the virus enters the skin together with the mosquito's saliva.

When he wasn ’ t trapping rats and squirrels in California, Blue directed mosquito eradication efforts to control yellow fever in New Orleans ( 1905 ), at the Jamestown Exposition ( 1907 ), and in Honolulu ( 1911 ), to help Hawaii prepare for traffic to follow the opening of the new Panama Canal.

When ingested by a mosquito, the microfilariae undergo a series of molts to the infective third larval stage, and then migrate to the salivary glands of the mosquito, where they wait to infect another host.

When Merritt Island was flooded with the goal of reducing the mosquito population around Kennedy Space Center, the sparrows ' nesting grounds were devastated, and their numbers plummeted.

When a female Anopheles mosquito bites an infected person, gametocytes and other stages of the parasite are transferred to the stomach where further development occur.

When the mosquito bites a healthy person, thousands of sporozoites are infected into the blood along with the saliva and the cycle starts again.

When the Anopheles mosquito takes a blood meal from an infected individual, gametocytes are ingested from the infected person.

When it was decided that Asteroids would be a vector game as well, Delman modified a Lunar Lander circuit board for Ed Logg.

* In linear algebra, an endomorphism of a vector space V is a linear operator V → V. An automorphism is an invertible linear operator on V. When the vector space is finite-dimensional, the automorphism group of V is the same as the general linear group, GL ( V ).

When the angular velocity of this co-rotating frame is not constant, that is, for non-circular orbits, other fictitious forces — the Coriolis force and the Euler force — will arise, but can be ignored since they will cancel each other, yielding a net zero acceleration transverse to the moving radial vector, as required by the starting assumption that the vector co-rotates with the planet.

When applied to vector spaces of functions ( which typically are infinite-dimensional ), dual spaces are employed for defining and studying concepts like measures, distributions, and Hilbert spaces.

When defined for a topological vector space there is a subspace of this dual space, corresponding to continuous linear functionals, which constitutes a continuous dual space.

When the evolution map Φ < sup > t </ sup > ( or the vector field it is derived from ) depends on a parameter μ, the structure of the phase space will also depend on this parameter.

When light crosses an optical element the resulting polarization of the emerging light is found by taking the product of the Jones matrix of the optical element and the Jones vector of the incident light.

When making a gun-like configuration, with the middle finger crossing under the index finger, the fingers represent the velocity vector, magnetic field vector, and force vector, respectively.

When only the magnitude and direction of the vector matter, then the particular initial point is of no importance, and the vector is called a free vector.

When the length of vectors is defined, it is possible to also define a dot product — a scalar-valued product of two vectors — which gives a convenient algebraic characterization of both length ( the square root of the dot product of a vector by itself ) and angle ( a function of the dot product between any two vectors ).

When the coordinates are transformed, for example by rotation or stretching, then the components of the vector also transform.

When considered a vector, weight is often denoted by a bold letter W.

When the system S is prepared in a pure state, it is associated with a vector in H. Measurable quantities are associated with Hermitian operators acting on H: these are referred to as observables.

When new SIMD architectures need to be distinguished from older ones, the newer architectures are then considered " short-vector " architectures, as earlier SIMD and vector supercomputers had vector lengths from 64 to 64, 000.

When applied to a tangent vector X to the surface, the shape operator is the tangential component of the rate of change of the normal vector when moved along a curve on the surface tangent to X.

When a vector field represents force, the line integral of a vector field represents the work done by a force moving along a path, and under this interpretation conservation of energy is exhibited as a special case of the fundamental theorem of calculus.

When disruptive change has penetrated to the third level of social order, the process of disruption rapidly reaches a point of no return.

When a person has thoughtlessly or deliberately caused us pain or hardship it is not always easy to say, `` Just forget it ''.

When a city has arranged things like this you cannot easily change them.

When mold has more than one design cavity, make individual paper patterns.

When the resin has hardened, mix up another batch with a pigment added if you wish.

When the whole bottom has hardened, use a disk sander to feather the edges of the cloth at the keel line and near the spray rail.

When we look at countries like Iran, Iraq, Pakistan, and Burma, where substantial progress has been made in creating a minimum supply of modern men and of social overhead capital, and where institutions of centralized government exist, we find a second category of countries with a different set of problems and hence different priorities for policy.

When the information cell for Af has been determined, it is saved as a representation of Af.

) When the complete file has been read, the grammatical descriptions for all text forms found in the dictionary have been stored in the W-region ; ;

When a word represents a larger construction of which it is the only expressed part, it normally has more stress than it would have in fully expressed construction.

When ity is added, real clearly has two syllables.

When dealing with the actual relation of philosophy to the sociology of knowledge, or better the role of philosophy in assisting research on the social sources of ideas, one has to become necessarily selective.

When all has been said, however, the big branch store remains a major break with history in the development of American retailing.

When they do that my wife has to drive me to work in the big car.

When that fear has been removed by faith in Jesus Christ, when we know that He is our Savior, that He has paid our debt with His blood, that He has met the demands of God's justice and thus has turned His wrath away -- when we know that, we have peace with God in our hearts ; ;
