  • Inspired by Lorenz’ remarkable chaotic flow, we describe in this paper the structure of all C 1 robust transitive sets with singularities for flows on closed 3-manifolds: they are partially hyperbolic with volume-expanding central direction, and are either attractors or repellers. In particular, any C 1 robust attractor with singularities for flows on closed 3-manifolds always has an invariant foliation whose leaves are forward contracted by the flow, and has positive Lyapunov exponent at every orbit, showing that any C 1 robust attractor resembles a geometric Lorenz attractor. ...

  • Bowen’s formula relates the Hausdorff dimension of a conformal repeller to the zero of a ‘pressure’ function. We present an elementary, self-contained proof to show that Bowen’s formula holds for C 1 conformal repellers. We consider time-dependent conformal repellers obtained as invariant subsets for sequences of conformally expanding maps within a suitable class.

  • Magnets are pieces of metal that have the ability to attract other metals. Every magnet has two poles: a north and a south. Much like electrical charges, two similar magnetic poles repel each other; while opposite magnetic poles attract each other. Magnets have a continuous force around them that is known as a magnetic field. This field enables them to attract other metals. Figure 1 illustrates this force using bar and horseshoe magnets.

  • ¾ With the modern knowledge about the structure of matter we know that electric charges come from elementary particles: negatively charged electron and positively charged proton. In nuclei there are also neutron with no charge. Interaction between charges: two positive charges or two negative charges repel each other. A positive charge and a negative charge attract each other. This interaction is called the static electric interaction.

  • Phenolic compounds represent a large group of molecules with a variety of functions in plant growth, development, and defense. Phenolic compounds include signaling molecules, pigments and flavors that can attract or repel, as well as compounds that can protect the plant against insects, fungi, bacteria, and viruses. Most phenolic compounds are present as esters or glycosides rather than as free compounds. Tannins and lignin are phenolic polymers.

  • Although magnetism has been known since ancient times, the connection between electricity and magnetism was not discovered until the early 19th century. Electromagnetics is the study of electric and magnetic field behavior. These fields arise from charged particles both at rest and in motion, and they may exert forces on other charged particles and materials. Hans Christian Oersted (a Danish scientist) demonstrated the relation between electricity and magnetism. In 1819, he showed that a compass needle could be deflected by a current-carrying conductor.

  • Pesticides are divided to insecticides, fungicides, herbicides, rodenticides, acaricides and nematocides according to the organisms that they affect. There are various forms of insecticides; most are repellants or insect growth regulators used in agriculture, public health, horticulture or food storage. It is evident that insecticides have been used to boost food production to a considerable extent and to control disease vectors.

  • Introduction: Nowadays, p-dichlorobenzene (paradichlorobenzene, 1,4-dichlorobenzene) is becoming more popular than naphthalene as a moth repellant (insecticide) worldwide. The discrimination between p-dichlorobenzene and naphthalene is usually difficult only by their smells and their appearances. However, specific gravities of their crystals are different; they are 1.152 and 1.5 for naphthalene and p-dichlorobenzene, respectively.

  • Introduction: Naphthalene (naphthalin) is being widely used as a moth repellant (insecticide), and being sold at supermarkets and general stores. Since one package of the compound usually contains as much as 1.8–5 g of naphthalene, the accidental ingestion of such a product by a small infant may cause fatality. However, recently, p-dichlorobenzene products, to be dealt with in the next chapter, have become more popular as a moth repellant.

  • For decades, the majority of ophthalmologists have been embarrassed by and highly suspicious of refractive surgery, at times with good justification. They have been repelled by its tactics in patient recruitment, uneasy about its seemingly cavalier use without longterm data, eager to defend its unsuspecting victims, and deeply concerned that its shortterm benefits are outweighed by its burdensome long-term consequences.

  • But with other POPs the transition to safer alternatives will require more effort. Alternatives may be more expensive and their manufacture and use more complicated. That could put developing countries in an awkward spot – struggling from day to day, the world's poor tend to use what they can afford and what is available. So it is not enough for the Convention simply to say No to its target list of POPs: It must also help governments find a way to say Yes to replacement solutions. Take the case of DDT.
