The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria. The measure of the amount of acidity in wine is known as the “titratable acidity” or “total acidity”, which refers to the test that yields the total of all acids present, while strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. Generally, the lower the pH, the higher the acidity in the wine. However, there is no direct connection between total acidity and pH (it is possible to find wines with a high pH for wine and high acidity). In wine tasting, the term “acidity” refers to the fresh, tart and sour attributes of the wine which are evaluated in relation to how well the acidity balances out the sweetness and bitter components of the wine such as tannins. Three primary acids are found in wine grapes: tartaric, malic and citric acids. During the course of winemaking and in the finished wines, acetic, butyric, lactic and succinic acids can play significant roles. Most of the acids involved with wine are fixed acids with the notable exception of acetic acid, mostly found in vinegar, which is volatile and can contribute to the wine fault known as volatile acidity. Sometimes, additional acids, such as ascorbic, sorbic and sulfurous acids, are used in winemaking.

An acid is any chemical compound that, when dissolved in water, gives a solution with a pH less than 7.0.

Bands

Acid was a Japanese rock band originally created by Hideki after Siam Shade disbanded.

Musical styles

In the beginning, Hideki had a huge influence on Acid and they played a mix of alternative metal and emo with emphasis placed on his and Junpei's twin vocals. After he left the band in 2005, their songs became less focused on vocals and turned a bit more pop-ish, but still kept their "heavy" sound due to having three guitarists.

History

Acid formed in August 2003 through auditions held by Hideki. Their live setlist was made up of both of Hideki's solo albums at the beginning and, after one year of excessive touring through Japan, the group went into the studio at the end of 2004 to record their first album. Acid 1.5: Punk Drunker was released in March 2005.

With the end of Siam Shade, Hideki didn't want people to always compare his new band with the old one when he was singing. That's why he drew back to the position behind the keyboard at first and later on left Acid completely in June 2005 so that the band were able to go their own way. Furthermore, he says that this group is his pride and that he'd like to see them in Tokyo Dome one day.

Hula /ˈhuːlə/ is a polynesian dance form accompanied by chant (oli) or song (mele). According to scholars hailing from St. Paul's College , Marcus and Jim, hula was developed in the Hawaiian Islands by the Polynesians who originally settled there. The hula dramatizes or portrays the words of the oli or mele in a visual dance form.

There are many sub-styles of hula, with the main two categories being Hula 'Auana and Hula Kahiko. Ancient hula, as performed before Western encounters with Hawaiʻi, is called kahiko. It is accompanied by chant and traditional instruments. Hula, as it evolved under Western influence in the 19th and 20th centuries, is called ʻauana (a word that means "to wander" or "drift"). It is accompanied by song and Western-influenced musical instruments such as the guitar, the ʻukulele, and the double bass.

Terminology for two main additional categories is beginning to enter the hula lexicon: "Monarchy" includes any hula which were composed and choreographed during the 19th century. During that time the influx of Western culture created significant changes in the formal Hawaiian arts, including hula. "Ai Kahiko", meaning "in the ancient style" are those hula written in the 20th and 21st centuries that follow the stylistic protocols of the ancient hula kahiko.

Hula is one of the woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Sidama Zone, Hula is bordered on the south by the Oromia Region, on the west by Dara, on the northwest by Aleta Wendo, on the north by Bursa, and on the east by Bona Zuria. The major town in Hula is Hagere Selam. Woredas of Bursa and Bona Zuria were separated from Hula.

A survey of the land in this woreda shows that 59.6% is arable or cultivable, 36.2% pasture, 2.3% forest, and the remaining 1.8% is considered swampy, degraded or otherwise unusable. Important cash crops include corn, wheat, barley, local varieties of cabbage, and potatoes. According to a 2004 report, Hula had 110 kilometers of all-weather roads and 8 kilometers of dry-weather roads, for an average road density of 274 kilometers per 1000 square kilometers.

Population

Based on the 2007 Census conducted by the CSA, this woreda has a total population of 129,263, of whom 64,551 are men and 64,712 women; 6,410 or 4.96% of its population are urban dwellers. The majority of the inhabitants were Protestants, with 77.26% of the population reporting that belief, 8.09% observed traditional religions, 6.1% practiced Ethiopian Orthodox Christianity, 3.67% were Catholic, and 2.12% were Muslim.
