Dengue

Dengue is a flu-like viral disease spread by the bite of infected mosquitoes. Dengue hemorrhagic fever is a severe, often fatal, complication of dengue. Dengue occurs in most tropical areas of the world. Most U.S. cases occur in travelers returning from abroad, but the dengue risk is increasing for persons living along the Texas-Mexico border and in other parts of the southern United States. There is no specific treatment for dengue.

Prevention centers on avoiding mosquito bites in areas where dengue occurs or might occur and eliminating breeding sites. Dengue and dengue hemorrhagic fever are caused by any of the dengue family of viruses. Infection with one virus does not protect a person against infection with another. Dengue is spread by the bite of an Aedes mosquito. The mosquito transmits the disease by biting an infected person and then biting someone else.

Home Decorations

Dolls were issued in England as Action Girl. These dolls were very similar to the US-issued dolls except that their eyes were side glancing and their hair was different. The US dolls had a piece of hair on other side of the face pulled up into a bow on top of the head. The Action Girl dolls had straight hair with no bows. Desktop Décor objects are also available.

The Action Girl dolls also had their own line of clothing. They also came out as a special Grants doll called Donna. These dolls had curly hair pulled to one side. It is used for home decorations.

The Teddy bear is a stuffed toy bear for children. It is an enduring, traditional form of stuffed animal, often serving the purpose of comforting upset young children. In recent times, some teddy bears, Wall Clocks have become expensive collector's items are used as a home accents.

The word art is also used to apply judgments of value, as in such expressions as "that meal was a work of art", or "the art of deception,”. It is this use of the word as a measure of high quality and high value that gives the term its flavor of subjectivity.

Waste Water Treatment

A standard wastewater treatment train would typically consist of a primary clarifier system to remove solid and floating materials, a secondary treatment system consisting of an aeration basin followed by flocculation and sedimentation or an activated sludge system and secondary clarifiers, a tertiary biological nitrogen removal system, and a final tertiary disinfections unit.

The aeration basin/activated sludge system removes organic material by growing bacteria. The secondary clarifier removes the activated sludge from the water. The tertiary system is becoming more prevalent to remove nitrogen and phosphorus and do final disinfections of the water prior to its discharge to a surface water stream or ocean outfall. Before reentering into a body of water, the wastewater gets treated under a multi-stage process then only the water gets renovated and it is used for application

Anaerobic processes are widely applied in the treatment of industrial wastewaters and biological sludge. Some wastewater may be highly treated and reused as reclaimed water. For some wastewaters ecological approaches using reed bed systems such as constructed wetlands may be appropriate. Modern systems include tertiary treatment by micro filtration or synthetic membranes. After membrane filtration, the treated wastewater is indistinguishable from waters of natural origin of drinking quality.
