Sunglasses

Sunglasses may be made with either prescription or non-prescription (i.e. Plano) lenses that are darkened to offer protection against bright visible light. Good quality sunglasses should also protect against ultraviolet light. Due to changes in the atmosphere, ultraviolet levels are much elevated than in the past and ultraviolet protection for eyes and skin is even more important. It is possible to have lenses that seem very dark and yet offer little ultraviolet protection. Sunglasses fluctuate greatly and many offer more style than protection.

Flower anatomy

Flowering plants are heterosporangiate and the pollen and ovules are produced in different organs, but these are together in a bisporangiate strobilus that is the typical flower. A flower is regarded as a modified stem with shortened internodes and behavior, at its nodes, structures that may be highly adapted leaves. In essence, a flower structure forms on a modified shoot or axis with an apical moisten that does not grow constantly. The stem is called a pedicel, the end of which is the tours or container.

Marketing

Marketing is one of the most significant functions in business. It is the regulation required to understand customers' needs and the benefits they seek. Academia does not have one commonly agreed upon description. Even after a better part of a century the dispute continues. In a nutshell it consists of the social and managerial processes by which goods or services and value are exchanged in order to fulfill the needs and wants of individuals or groups. Although many people appear to think that "marketing" and "advertising" are synonymous, they are not. Advertising is simply one of the lots of processes that together constitute marketing.

Web proxy

Proxies that hub on WWW traffic are called web proxies. Many web proxies try to block offensive web content. Other web proxies reformat web pages for an exact purpose or audience (e.g., cell phones and PDAs or persons with disabilities). Network operators can also set up proxies to intercept computer viruses and other hostile content served from remote web pages.

Many organizations — including schools, corporations, and countries — use proxy servers to implement acceptable network use policies or to provide security, anti-malware and/or caching services. A traditional web proxy is not translucent to the client application, which must be configured to use the proxy (manually or with a configuration script). In some cases, where substitute means of connection to the Internet are available, the user may be able to avoid policy control by simply resetting the client configuration and bypassing the proxy. Furthermore administration of browser configuration can be a load for network administrators.
