The Apothecary or The Chemist byGabriël Metsu (c. 1651–67)
Pharmacy is the science and technique of preparing and dispensing drugs. It is a health profession that links health sciences with chemical sciences and aims to ensure the safe and effective use of pharmaceutical drugs.
The scope of pharmacy practice includes more traditional roles such as compounding and dispensing medications, and it also includes more modern services related to health care, including clinical services, reviewing medications for safety and efficacy, and providing drug information. Pharmacists, therefore, are the experts on drug therapy and are the primary health professionals who optimize use of medication for the benefit of the patients.
An establishment in which pharmacy (in the first sense) is practiced is called a pharmacy (this term is more common in the United States) or a chemist's (which is more common in Great Britain). In the United States and Canada, drugstores commonly sell drugs, as well as miscellaneous items such as confectionery, cosmeticsoffice supplies, and magazines and occasionally refreshments and groceries.
The word pharmacy is derived from its root word pharma which was a term used since the 15th–17th centuries. However, the original Greek roots from pharmakos imply sorcery or even poison. In addition to pharma responsibilities, the pharma offered general medical advice and a range of services that are now performed solely by other specialist practitioners, such as surgery and midwifery. The pharma (as it was referred to) often operated through a retail shop which, in addition to ingredients for medicines, sold tobacco and patent medicines. Often the place that did this was called an apothecary and several languages have this as the dominant term, though their practices are more akin to a modern pharmacy, in English the term apothecary would today be seen as outdated or only approproriate if herbal remedies were on offer to a large extent. The pharmas also used many other herbs not listed. The Greek word Pharmakeia (Greekφαρμακεία) derives from pharmakon (φάρμακον), meaning "drug", "medicine" (or "poison").[1][n 1]
In its investigation of herbal and chemical ingredients, the work of the pharma may be regarded as a precursor of the modern sciences of chemistry and pharmacology, prior to the formulation of the scientific method.

La pharmacie (du grec φάρμακον/pharmakôn signifiant à la fois le remède et le poison) est la science s'intéressant à la conception, au mode d'action, à la préparation et à la dispensation des médicaments. Cette dispensation prend en compte les interactions médicamenteuses possibles entre les molécules chimiques ou bien encore, les interactions avec des produits comestibles. Elle permet également la vérification des doses et/ou d'éventuelles contre-indications. C'est à la fois une branche de la biologie, de la chimie et de la médecine.
Le terme pharmacie désigne également une officine, soit un lieu destiné à l'entreposage et à la dispensation de médicament. Ce lieu est sous la responsabilité d'un pharmacien qui peut y fabriquer des préparations magistrales ordonnées par un médecin pour un patient donné et superviser le travail des préparateurs en pharmacie en France ou des Assistants techniques en pharmacie au Canada. La dispensation des médicaments dans une officine de pharmacie se fait sous l'entière responsabilité du pharmacien, que ce soient des médicaments délivrés sur prescription médicale ou non.
Au sein de l'officine, le pharmacien peut également faire le suivi de la médication du patient, substituer un princeps par un générique, adapter les posologies, renouveler les traitements des pathologies chroniques et proposer des modifications de thérapeutique en accord avec le médecin. Un dialogue entre ces deux professionnels de santé est essentiel à la santé publique.

Climate

From Wikipedia, the free encyclopedia
This page presents a general overview of Earth's climate system. An introduction to how Earth's climate can change is found at Climate change, and discussion of the current warming of the climate system is presented at global warming. For other uses of "climate", see Climate (disambiguation)
Climate is the statistics (usually, mean or variability) of weather, usually over a 30-year interval.[1][2] It is measured by assessing the patterns of variation in temperaturehumidityatmospheric pressurewindprecipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region.
A region's climate is generated by the climate system, which has five components: atmospherehydrospherecryospherelithosphere, and biosphere.[3]
The climate of a location is affected by its latitudeterrain, and altitude, as well as nearby water bodies and their currents. Climates can be classified according to the average and the typical ranges of different variables, most commonly temperature and precipitation. The most commonly used classification scheme was Köppen climate classification originally developed by Wladimir Köppen. The Thornthwaite system,[4] in use since 1948, incorporates evapotranspiration along with temperature and precipitation information and is used in studying biological diversity and the potential effects on it of climate changes. The Bergeron and Spatial Synoptic Classification systems focus on the origin of air masses that define the climate of a region.
Paleoclimatology is the study of ancient climates. Since direct observations of climate are not available before the 19th century, paleoclimates are inferred from proxy variables that include non-biotic evidence such as sediments found in lake beds and ice cores, and biotic evidence such as tree rings and coral. Climate models are mathematical models of past, present and future climates. Climate change may occur over long and short timescales from a variety of factors; recent warming is discussed in global warming.

تصنيف أنماط المناخ حول العالم.
المناخ (بالإنجليزية: Climate) هو حالة الجو السائدة في الأجهزة المستعملة لجمع معلومات عن مكان معين لفترة زمنية طويلة.[1].
المناخ هو مجموع الظروف الجوية التي تسود في منطقة معينة و يمكن تصنيف مكوناته كالتالي :
عناصر طاقة : (إضاءة – درجة الحرارة)
عناصر مائية : (أمطار – رطوبة – ضباب – ندي – سحاب)
عناصر ميكانيكية : (رياح – ثلوج)
وتسمى هذه العناصر بالعوامل المناخية و هي مرتبطة ببعضها البعض بشكل كبير، ورغم تعدد هذه العوامل إلا أن الإحصائيين يحددون المناخ بمنطقة معينة اعتمادا على الأمطار والحرارة.
