warming. The ozone is a thin layer of O3 that surrounds the earth and helps to regulate climate and temperature. Without the ozone there would be a lot more insolation and the earth would probably be too hot to populate. Chlorofluorocarbons or CFC’s were used in refrigerators‚ air conditioners‚ aerosol cans and have also been used in fire fighting. In September 16‚ 1987 a group of nations signed the Montreal Protocol to protect the ozone layer by phasing out the use of numerous

original. The design of TCP was comprehensively predisposed by what has come to be known as the "end-to-end argument". As per it relating to the Internet‚ the end-to-end argument says that by putting excessive intelligence in physical and link layers to handle error control‚ encryption or flow control you unnecessarily complicate the system. This is due to these tasks will usually need to be done at the endpoints nevertheless. The outcome of an end-to-end network at that point‚ is to offer marginal

architecture into seven distinct layers: the Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data-Link‚ and Physical Layers. As a result it is frequently referred to as the OSI Seven Layer Model. A layer is a collection of theoretically similar functions that provide services to the layer directly above it and obtains service from the layer beneath it. On each single layer an instance provides services to the instances at the layer above and requests service from the layer beneath. An example of this

implementation of Web Services in computer networks. It relies on Extensible Markup Language (XML) for its message format‚ and usually relies on other Application Layer protocols‚ most notably Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP)‚ for message negotiation and transmission. SOAP can form the foundation layer of a web services protocol stack‚ providing a basic messaging framework upon which web services can be built. This XML based protocol consists of three parts:

Chapter 7: Neurulation and the Formation of Axial Structures Neurulation The stage of organogenesis in vertebrate embryos‚ during which the neural tube is transformed into the primitive structures that will later develop into the central nervous system. In development‚ this starts with the first traces of formation of the neural plate and ends with closure of the neural tube. Induction Process by which the presence of one tissue influences the development of another. Some considerations:

Globalization and the Pollution Globalisation is an universal phenomenon which was introduced with the aim of integrating societies‚economies and cultures through a common link of trading policies‚technology and communication.With the advent of globalisation though the standard of economy has improved‚it also brought many new issues into concern. Brain drain‚pollution and spread of diseases are the major problems the world is facing today.For a large extend the factor behind this is globalisation

Frog Embryology The Egg The frog egg is a huge cell; its volume is over 1.6 million times larger than a normal frog cell. During embryonic development‚ the egg will be converted into a tadpole containing millions of cells but containing the same amount of organic matter. * The upper hemisphere of the egg — the animal pole — is dark. * The lower hemisphere — the vegetal pole — is light. * When deposited in the water and ready for fertilization‚ the haploid egg is at metaphase of meiosis
