CYBRIDS
The cytoplasmic hybrids, Where the nucleus is derived from only one parent and the cytoplasm is derived from both the parents are referred to as Cybrid or Cytoplast ( Cytoplasmic hybrids). The Phenomenon of formation of cybrids is regarded as Cybridization. Applications of Cybrids Cybrids are important for the transfer of Cytoplasmic male Sterility, antibiotic and herbicide resistance in agriculturally useful plants. Two different parental genome that can not reproduce sexually (a sexual or sterile) are recombined. Overcomes sexual incompatibility barriers.

Orange: Natural Insect Repellent
Many plants have insecticidal properties so they are also called natural insecticides. The orange (Citrus sinensus), is a valuable fruit not only for its edibility, but for the high quantities of the substance d- limonene, found in its peel and zest. D- Limonene is a pesticide and is found in many commercial insect repellents.Oil derived from orange peel has a 90 to 95 percent content of d-limonene, which is lethal to fleas, fire ants and flies. Limonene affects insects on contact, effectively suffocating them by damaging their respiratory systems. Many insects
Central Conicoids, Tangent Plane And Normal
The general Equation of second degree (conicoid) : The surface represented by the general equation of second degree in x,y,z is called a conicoid or quadric. The standard equation of the central conicoid –The surface represented by the equation ax²+by²+cz²=⊥ (1) possesses the property that all chords of the surface which pass through the origin are bisected at the origin.The conicoid represented by the equation (1) possesses a unique centre (origin) that is, the origin is the only point which possesses this property. This conicoid is therefore known as the
Time Rate Wage System And Its Effects
INTRODUCTION: Wages of workers are based on the time of production. When wages are decided on a time rate basis, the quantity of goods produced by a worker is not considered but he is paid wages on the basis of time spent by him in the factory. The time rate of wages can be determined per hour, per week or per month. This system of wages is prevalent in most of the industries.

Cahn – Ingold – Prelog priority sequence can be usefully applied in giving names to such a structure. The group of highest priority, on both the double bonded carbon atom is first chosen. If the two group of highest priority are on the opposite side of the double bond. The alphabet E (from the German word Entagagen meaning opposite) is used for the structure and if the groups of highest priority are on the same side the alphabet Z (from German word, Zussamen meaning together) is used.

Water is needed not only for drinking, but also cooking, cleaning, and sanitizing. But it might not be clean or filtered because of many pollutants present in water. Fortunately, there is an interesting idea for helping filter and clean available water supplies.Yes, in a pinch banana peels can be used to filter water. Banana peels contain sulfur, nitrogen, carboxylic acid and other atoms that function pretty much the same way magnets do in terms of attracting heavy metals. These molecules are not affected human health. This is great news since heavy
Riggs Ideal Model in Comparative Public Administration
Fred Riggs, who is known as the Father of Comparative Public Administration developed a typology in 1956-1957 named as ‘AGRARIA-TRANSITIA-INDUSTRIA. This model was fully developed in 1957.It reflects the features of two societies viz.Agrarian and Industrial societies. Agrarian society is the condition of society where there is dominance of agricultural activities. It is mainly known for its various features like Ascriptive values, functionally diffuse pattern, limited spatial mobility, traditional patterns and norms ,etc. Riggs gave an example of Imperial China in this context. Another extreme of this theory is an Industria

Alternation of Generation in Pteridophytes
A pteridophyte is a vascular plant (with xylem and phloem) that reproduces via spores, and therefore was a member of the former and now invalid taxon Pteridophyta.Because pteridophytes produce neither flowers nor seeds, they are also referred to as “cryptogams”. The pteridophytes include the ferns, horsetails, and the lycophytes (clubmosses, spikemosses, and quillworts). “Alternation of generation” term used by Hofmeister in 1851. He observed that in mosses and ferns there are two types of morphologically distinct individuals present in the life cycle. Both alternate in a life cycle back to back.

RIGGS FUSED PRISMATIC DIFFRACTED MODEL
Fred Riggs, who is known as the Father of Comparative Public Administration is propounder of ecological approach. He wrote the book “The Ecology of Public Administration” in 1962 in which he threw light on the relationship & interaction of an administration with its external surroundings. He analyzed that many factors like political, social, economic, administrative etc. are influenced by its environment & in turn influences the environment in which it works. In his approach, he described two types of models-[A] Agraria-Transita-Industria Model [1956-1957][B] Fused-Prismatic-Diffracted Model [1959] [Outcome of ATI MODEL]Fused-Prismatic-Diffracted Model
