Uses of Alcoholic drinks

 

In many countries, alcoholic beverages are commonly consumed at the major daily meals (lunch and dinner).In places and areas with poor public sanitation, such as Medieval Europe, consumption of alcoholic drinks (particularly weak or “small” beer) was one method of avoiding water-borne diseases such as cholera. Though alcohol kills bacteria, the low concentration in beer or even wine will have only a limited effect. Probably the boiling of water, which is required for the brewing of beer, and the growth of yeast, which would tend to crowd out other micro-organisms, were more important than the alcohol itself. Additionally, the ethanol (and possibly other ingredients) of alcoholic beverages allows them to be stored for months or years in simple wood or clay containers without spoiling; for this reason they were commonly utilized onboard sailing vessels as a key (or even the sole) source of hydration for the crew, especially during the long voyages of the early modern period.In colder climates, strong alcoholic beverages such as vodka are popularly seen as a way to “warm up” the body, possibly because ethanol is a quickly absorbed source of food energy and because it dilates peripheral blood vessels (Peripherovascular dilation) — a dangerous misconception, as the perception of warmth is actually caused by the transfer of heat from the body’s core to its extremities where it is quickly lost to the environment.In many cultures, both contemporary and historical, alcoholic beverages — mostly because of their neurological effects — have also played an important role in various kinds of social interaction, providing a form of “liquid courage” (those who consume it typically gain confidence and lose discretion). While other psychoactive drugs (such as opium, coca, khat, cannabis, kava-kava, etc.) also have millennial traditions of social use, only coffee, tea, betel, and tobacco are currently as universally used and accepted as ethanol.

What is habeas corpus

April 27th, 2008 | Category: legal terms

Habeas corpus 

Lat. “you have the body” Prisoners often seek release by filing a petition for a writ of habeas corpus. A writ of habeas corpus is a judicial mandate to a prison official ordering that an inmate be brought to the court so it can be determined whether or not that person is imprisoned lawfully and whether or not he should be released from custody. A habeas corpus petition is a petition filed with a court by a person who objects to his own or another’s detention or imprisonment. The petition must show that the court ordering the detention or imprisonment made a legal or factual error. Habeas corpus petitions are usually filed by persons serving prison sentences. In family law, a parent who has been denied custody of his child by a trial court may file a habeas corpus petition. Also, a party may file a habeas corpus petition if a judge declares her in contempt of court and jails or threatens to jail her.

Earthquake

April 04th, 2008 | Category: FYI

An earthquake is a shaking of the ground caused by the sudden breaking and movement of large sections (tectonic plates) of the earth’s rocky outermost crust. The edges of the tectonic plates are marked by faults (or fractures). Most earthquakes occur along the fault lines when the plates slide past each other or collide against each other.

The shifting masses send out shock waves that may be powerful enough to

  • alter the surface of the Earth, thrusting up cliffs and opening great cracks in the ground and
  • cause great damage … collapse of buildings and other man-made structures, broken power and gas lines (and the consequent fire), landslides, snow avalanches, tsunamis (giant sea waves) and volcanic eruptions.

Global Warming

April 04th, 2008 | Category: FYI

Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century and its projected continuation.

The global average air temperature near the Earth’s surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes “most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations” via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward. These basic conclusions have been endorsed by at least thirty scientific societie and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with some findings of the IPCC, the overwhelming majority of scientists working on climate change agree with the IPCC’s main conclusions.
