Definitions &Translations Cephalization is considered an evolutionary trend, whereby nervous tissue, over many generations, becomes concentrated toward one end of an organism. This process eventually produces a head region with sensory organs.Cephalization is intrinsically connected with a change in symmetry.It accompanied the move to bilateral symmetry made in flatworms, with ocelli and pinnae placed in the head region.his process eventually produces a head region with sensory organs.

Human fertilization Illustration depicting ovulation and fertilization. Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the uterine tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century.

Lyophilization of Parenterals Products are manufactured in the lyophilized form due to their instability when in solution. Many of the antibiotics, such as some of the semi-synthetic penicillins, cephalosporins, and also some of the salts of erythromycin, doxycycline and chloramphenicol are made by the lyophilization process.

Adult-onset Hydrocephalus The term hydrocephalus is derived from two words: hydro, meaning water, and cephalus, referring to the head. Hydrocephalus is a condition in which excess cerebrospinal fluid (CSF) builds up within the ventricles (fluid-containing cavities) of the brain and may increase pressure within the head. Although hydrocephalus often is described as water on the brain, the water is actually CSF — a clear fluid surrounding the brain and spinal cord.

What is cephalization? Cephalization means that the animal has a defined head region in which there is a lot of nervous tissue (such as the brain in humans).Sponges are not cephalized because t … hey do not have defined head region nor do they have a central location for their nervous system.ephalization is a tendency in the evolution of organisms to concentrate the sensory and neural organs in an anterior head. Basically, the organism has a brain.

When Do You Have to Testify in Court? Juries are not allowed to suppose that because a defendant does not testify, he or she is probably guilty. If you are a witness to a crime, or if you are called as a witness by either side during a trial, you do not have to appear to testify unless you have been subpoenaed. A SUBPOENA (pronounced sub-pee-nuh) is a court order commanding you to appear in court.

Chapter 14 â Crystallization and Dissolution Crystallization is the process by which solid crystals are formed from a liquid or from an amorphous solid. Controlled crystallization serves in the recovery of sugar, salt and other crystalline products, in numerous confectionery applications, and in the winterization of liquid oils.ntroduction. Crystallization is the process by which solid crystals are formed from a liquid (Decloux, 2002, Hartel, 2001 and Mersmann, 1995) or from an amorphous solid (Jouppila and Roos, 1994). In the case of crystallization from a liquid, the liquid medium is either a supersaturated solution or a supercooled melt.

Crystallization of polymers Crystallization of polymers. Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from the melt, mechanical stretching or solvent evaporation.

What is Cephalic Presentation? In obstetrics, the term cephalic is used to refer to a baby that is delivered headfirst, as he should be. A cephalic presentation may require delivering using a C-section. Presentations can become complicated when a woman is carrying multiples. An obstetrician can do an exam to determine if the fetus is in the right place.

Auralization Auralization is the technique of creation and reproduction of sound on the basis of computer data. With this tool is it possible to predict the character of sound signals which are generated at the source and modified by reinforcement, propagation and transmission in systems such as rooms, buildings, vehicles or other technical devices.
