Dublin
Dublin (; , or ) is the capital and largest city of Republic of Ireland, Ireland. On a bay at the mouth of the River Liffey, it is in the Provinces of Ireland, province of Leinster, bordered on the south by the Dublin Mountains, a part of the Wicklow Mountains range. At the 2016 census of Ireland, 2016 census it had a population of 1,173,179, while the preliminary results of the 2022 census of Ireland, 2022 census recorded that County Dublin as a whole had a population of 1,450,701, and that the population of the Greater Dublin Area was over 2 million, or roughly 40% of the Republic of Ireland's total population. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kings of Dublin, Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoxia (medical)
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either '' generalized'', affecting the whole body, or ''local'', affecting a region of the body. Although hypoxia is often a pathological condition, variations in arterial oxygen concentrations can be part of the normal physiology, for example, during strenuous physical exercise.. Hypoxia differs from hypoxemia and anoxemia, in that hypoxia refers to a state in which oxygen present in a tissue or the whole body is insufficient, whereas hypoxemia and anoxemia refer specifically to states that have low or no oxygen in the blood. Hypoxia in which there is complete absence of oxygen supply is referred to as anoxia. Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised general ...

Sinn Féin
Sinn Féin ( , ; en, " eOurselves") is an Irish republican and democratic socialist political party active throughout both the Republic of Ireland and Northern Ireland. The original Sinn Féin organisation was founded in 1905 by Arthur Griffith. Its members founded the revolutionary Irish Republic and its parliament, the First Dáil, during the Irish War of Independence. The party split in the aftermath of the Irish Civil War, giving rise to the two traditionally dominant parties of southern Irish politics: Fianna Fáil, and Cumann na nGaedheal (which became Fine Gael). For several decades the remaining Sinn Féin organisation was small without parliamentary representation. Another split in 1970 at the start of the Troubles led to the Sinn Féin of today, with the other faction eventually becoming the Workers' Party. During the Troubles, Sinn Féin was associated with the Provisional Irish Republican Army (IRA). For most of that conflict, there were broadcasting bans on Si ...

Fluoride Therapy
Fluoride therapy is the use of fluoride for medical purposes. Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. It is typically used as a liquid, pill, or paste by mouth. Where public water supplies are fluoridated further fluoride by mouth is typically not needed. Fluoride has also been used to treat a number of bone diseases. Relatively high ingestion of fluoride by babies and children may result in white marks on the teeth known as fluorosis. Excessive ingestion by babies and children can also result in severe dental fluorosis, indicated by a brown or yellow coloring and weakness/brittleness of the teeth, or in severe cases, acute toxicity. Fluoride therapy typically uses the sodium fluoride form, though stannous fluoride may also be used. Fluoride decreases breakdown of teeth by acids, promotes remineralisation, and decreases the activity of bacteria. It is believed to work p ...

Secularism
Secularism is the principle of seeking to conduct human affairs based on Secularity, secular, Naturalism (philosophy), naturalistic considerations. Secularism is most commonly defined as the Separation of church and state, separation of religion from civil affairs and the state, and may be broadened to a similar position seeking to remove or to minimize the role of religion in any public sphere. The term "secularism" has a broad range of meanings, and in the most schematic, may encapsulate any stance that promotes the secular in any given context. It may connote anti-clericalism, atheism, Naturalism (philosophy), naturalism, Nonsectarian, non-sectarianism, Neutrality (philosophy), neutrality on topics of religion, or the complete removal of religious symbols from public institutions. As a philosophy, secularism seeks to interpret life based on principles derived solely from the material world, without recourse to religion. It shifts the focus from religion towards "temporal" a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate-change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The Instrumental temperature record, current rise in global average temperature is more rapid than previous changes, and is Scientific consensus on climate change, primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices Greenhouse gas emissions, increase greenhouse gases, notably carbon dioxide and Methane emissions, methane.

Vaccination
Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. Herd immunity protects those who may be immunocompromised and cannot get a vaccine because even a weakened version would harm them. The effectiveness of vaccination has been widely studied and verified. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the elimination of diseases such as polio and tetanus from much of the world. However, some diseases, such as measles outbreaks in America, have seen rising cases due to relative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or falsifiability, unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to Peer review, evaluation by other experts; absence of systematic practices when developing Hypothesis, hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. The demarcation problem, demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theory, scientific theories and pseudoscientific beliefs, but there is general agreement on examples such as ancient astronauts, climate change denial, dowsing, evolution denial, ...

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Irish Times
''The Irish Times'' is an Irish daily broadsheet newspaper and online digital publication. It launched on 29 March 1859. The editor is Ruadhán Mac Cormaic. It is published every day except Sundays. ''The Irish Times'' is considered a newspaper of record for Ireland. Though formed as a Protestant nationalist paper, within two decades and under new owners it had become the voice of British unionism in Ireland. It is no longer a pro unionist paper; it presents itself politically as "liberal and progressive", as well as being centre-right on economic issues. The editorship of the newspaper from 1859 until 1986 was controlled by the Anglo-Irish Protestant minority, only gaining its first nominal Irish Catholic editor 127 years into its existence. The paper's most prominent columnists include writer and arts commentator Fintan O'Toole and satirist Miriam Lord. The late Taoiseach Garret FitzGerald was once a columnist. Senior international figures, including Tony Blair and Bill Cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homeopathy
Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called '' similia similibus curentur'', or "like cures like". Homeopathic preparations are termed ''remedies'' and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product. Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent remember the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease. All relevant scientific knowledge about ...

Poisson Distribution
In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and Statistical independence, independently of the time since the last event. It is named after France, French mathematician Siméon Denis Poisson (; ). The Poisson distribution can also be used for the number of events in other specified interval types such as distance, area, or volume. For instance, a call center receives an average of 180 calls per hour, 24 hours a day. The calls are independent; receiving one does not change the probability of when the next one will arrive. The number of calls received during any minute has a Poisson probability distribution with mean 3: the most likely numbers are 2 and 3 but 1 and 4 are also likely and there is a small probability of it being as low as zero and a very smal ...
