Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag is an important factor in diurnal temperature variation: peak daily temperature generally occurs ''after'' noon, as air keeps net absorbing heat even after noon, and similarly minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground to waist height. Incoming solar radiation exceeds outgoing heat energy for many hours after ...

July Diurnalvariation US
July is the seventh month of the year in the Julian and Gregorian calendars and is the fourth of seven months to have a length of 31 days. It was named by the Roman Senate in honour of Roman general Julius Caesar in 44 B.C., it being the month of his birth. Before then it was called Quintilis, being the fifth month of the calendar that started with March. It is on average the warmest month in most of the Northern Hemisphere, where it is the second month of summer, and the coldest month in much of the Southern Hemisphere, where it is the second month of winter. The second half of the year commences in July. In the Southern Hemisphere, July is the seasonal equivalent of January in the Northern hemisphere. "Dog days" are considered to begin in early July in the Northern Hemisphere, when the hot sultry weather of summer usually starts. Spring lambs born in late winter or early spring are usually sold before 1 July. July symbols *July's birthstone is the ruby, which symbolize ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea wit ...

Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When blocked by clouds or reflected off other objects, sunlight is diffused. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day; this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D3 synthesis and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction ...

Sugar
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars, and are called oligosaccharides or polysaccharides. Starch is a glucose polymer found in plants, the most abundant source of energy in human food. Some other chemical substances, such as glycerol and sugar alcohols, may have a sweet taste, but are not classified as sugar. Sugars are found in the tissues of most plants. Honey and fruits are abundant natural sources of simple su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Inf ...

Grape
A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus '' Vitis''. Grapes are a non- climacteric type of fruit, generally occurring in clusters. The cultivation of grapes began perhaps 8,000 years ago, and the fruit has been used as human food over history. Eaten fresh or in dried form (as raisins, currants and sultanas), grapes also hold cultural significance in many parts of the world, particularly for their role in winemaking. Other grape-derived products include various types of jam, juice, vinegar and oil. History The Middle East is generally described as the homeland of grape and the cultivation of this plant began there 6,000–8,000 years ago. Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, leading to the discovery of alcoholic drinks such as wine. The earliest archeological evidence for a dominant position of wine-making in human culture dates from 8,000 years ago i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altitude
Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the "down" direction are commonly referred to as depth. In aviation In aviation, the term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used. Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or ...

Wine Regions
This list of wine-producing regions catalogues significant growing regions where vineyards are planted. Wine grapes mostly grow between the 30th and the 50th degree of latitude, in both the Northern and Southern hemispheres. Grapes will sometimes grow beyond this range, thus minor amounts of wine are made in some rather unexpected places. In 2014, the five largest producers of wine in the world were, in order, #Italy, Italy, #Spain, Spain, #France, France, the #United States, United States, and #China, China. Countries The following is a list of the top wine-producing countries and their volume of wine production for the year 2014 in tonnes, according to the Food and Agriculture Organization (FAO), which is an agency of the United Nations; this is the latest information available from the FAO. Their data show a total worldwide production of 31 million tonnes of wine with the top 15 producing countries accounting for over 90% of the total. Africa Algeria * Algiers Prov ...

Viticulture
Viticulture (from the Latin word for '' vine'') or winegrowing (wine growing) is the cultivation and harvesting of grapes. It is a branch of the science of horticulture. While the native territory of '' Vitis vinifera'', the common grape vine, ranges from Western Europe to the Persian shores of the Caspian Sea, the vine has demonstrated high levels of adaptability to new environments, hence viticulture can be found on every continent except Antarctica. Duties of the viticulturist include monitoring and controlling pests and diseases, fertilizing, irrigation, canopy management, monitoring fruit development and characteristics, deciding when to harvest, and vine pruning during the winter months. Viticulturists are often intimately involved with winemakers, because vineyard management and the resulting grape characteristics provide the basis from which winemaking can begin. A great number of varieties are now approved in the European Union as true grapes for winegrowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kayseri
Kayseri (; el, Καισάρεια) is a large industrialised city in Central Anatolia, Turkey, and the capital of Kayseri province. The Kayseri Metropolitan Municipality area is composed of five districts: the two central districts of Kocasinan and Melikgazi, and since 2004, also outlying Hacılar, İncesu and Talas. As of 31 December 2021, the province had a population of 1,434,357 of whom 1,175,886 live in the four urban districts, excluding İncesu which is not conurbated (i.e. not contiguous, having a largely non-protected buffer zone). Kayseri sits at the foot of Mount Erciyes ( Turkish: Erciyes Dağı), a dormant volcano that reaches an altitude of , more than 1,500 metres above the city's mean altitude. It contains a number of historic monuments, particularly from the Seljuk period. Tourists often pass through Kayseri en route to the attractions of Cappadocia to the west. Kayseri is served by Erkilet International Airport and is home to Erciyes Universit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Badajoz
Badajoz (; formerly written ''Badajos'' in English) is the capital of the Province of Badajoz in the autonomous community of Extremadura, Spain. It is situated close to the Portuguese border, on the left bank of the river Guadiana. The population in 2011 was 151,565. Originally a settlement by groups such as the Romans and the Visigoths, its previous name was Civitas Pacensis. Badajoz was conquered by the Moors in the 8th century, and became a Moorish kingdom, the Taifa of Badajoz. After the reconquista, the area was disputed between Spain and Portugal for several centuries with alternating control resulting in several wars including the Spanish War of Succession (1705), the Peninsular War (1808–1811), the Storming of Badajoz (1812), and the Spanish Civil War (1936). Spanish history is largely reflected in the town. Badajoz is the see of the Roman Catholic Archdiocese of Mérida-Badajoz. Prior to the merger of the Diocese of Mérida and the Diocese of Badajoz, Badajoz was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alvega
Alvega is a former ''freguesia'' ("civil parish"), located in the municipality of Abrantes, in Santarém District, Portugal. In 2013, the parish merged into the new parish Alvega e Concavada. The population in 2011 was 1,499, in an area of 55.33 km². History On top of a hilltop encountered to the southwest of the confluence of the Tagus River with the Lampreia River, in the area of Barca de Bandos, are the ruins of a fortress. The vestiges of the surface area indicate the presence of the Phoenicians and Greeks. By the time the Romans began occupying the Iberian peninsula around 130, the area was already an important community, designated ''Ayre'' or ''Aritium'', with river port that provided a military connection between Lisbon and Mérida. The destruction of the Roman fort was attributed to the invasion of Vandals, on their way to Andalusia. Of this Roman ''civitas'' there are still some buildings, house foundations and graves, underground galleries, likely the ruins of ...
