UN Day World Wildlife Day 2023 (and 50th Anniversary of first signing of CITES)   When: 3 March 2023 Theme: Partnerships for Wildlife Conservation Every 3rd of March, wildlife is celebrated all over the world for the UN World Wildlife Day . This date was chosen as it is the birthday of CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora , signed in 1973. This World Wildlife Day 2023 falls on the 50th Anniversary of CITES coming into being. Since its inception, CITES has stood at the junction of trade and conservation. It has sought to build partnerships and reconcile differences between the groups that are guided and governed by its regulations.

Covid 19 : What’s the main difference between N95 facemask and KN95 facemask ? ?

Image
N95 facemask and KN95 facemask Both are  respirator  masks , but the difference is that N95 masks are US standard for  respirator  masks  (Certification/ Class (Standard) United States NIOSH-42CFR84)   and KN95 are the Chinese standard for  respirator  masks  (Certification/ Class (Standard) China GB2626-2006) .  So  What's The Difference ? Search Results Web results Even though they both appear to be alike there is some difference  appearances aside, * the  US standard  American manufactured N95 masks  can in fact withhold more pressure than the later when person wearing it breaths . Lets list details and differences between them according to 3m standards.  Total inward leakage (TIL) -  N95 = nil ,  KN95 = ≤ 8% leakage . Inhalation resistance -   N95  = ≤ 343 Pa , KN95 = ≤ 350 Pa. Exhalation resistance -  N95   = ≤ 245 Pa , KN95 = ≤ 250 Pa . Exhalation valve leakage -    N95  =  ≤ 30 mL/min , KN95 =  0 Pa ≥ 20 sec . Force applied -  N95  = -245 Pa , KN95 =  -1180 Pa . *N95 masks,

Daylight Saving Time 2013: When to Set Your Clocks?

Image
In the United States where a one-hour shift occurs at 02:00 local time, in spring the clock jumps forward from the last moment of 01:59 standard time to 03:00 DST and that day has 23 hours, whereas in autumn the clock jumps backward from the last moment of 01:59 DST to 01:00 standard time, repeating that hour, and that day has 25 hours. A digital display of local time does not read 02:00 exactly at the shift to summertime, but instead jumps from 01:59:59.9 forward to 03:00:00.0. In the European Union, on the other hand, since the shift occurs at 01:00 UTC, the autumn shift happens an hour later than the spring shift, local time. Clock shifts are usually scheduled near a weekend midnight to lessen disruption to weekday schedules. A one-hour shift is customary, but Australia's Lord Howe Island uses a half-hour shift. [ 37 ] Twenty-minute and two-hour shifts have been used in the past. Coordination strategies differ when adjacent time zones shift clocks. The Europea

VHS: a viral disease of young fishes

VHS: a vesceroptropic disease of young fishes An acute to chronic vesceroptropic disease of young (fingerling to yearling) rainbow trout at 10 0 C or lower. Also in adult trouts and salmonids, but not usual. Etiology: VHSV (Viral Haemorrhagic Septicemia Virus) Viral characteristics: Bullet-shaped rhabdovirus, enveloped. Length- 180 nm, width- 70-85 nm, apical end rounded, other end flat. ss RNA, replication in cytoplasm. Sensitive to lipid solvents, detergents and proteolytic enzymes. Distribution: Trouts farms in European countries: Denmark, Italy, Germany, Switzerland and Spain (not in UK and USA). Signs and pathology: Acute: Poor feeding. High mortality. Dark skin, exophthalmia. Pale gills, anaemia. Widespread internal haemorrhages in skeletal muscles and viscera. Hyperemic and swollen kidney and liver. Empty intestine. Hemorrhages in muscle and kidney. Focal necrosis in liver. Chronic: Low mortality. Dark skin. Exophthalmia.

Do You Know? Fish facts

Do You Know? (Fisheries Facts) Blue wheal is the largest animal of the world reaching up to 10 m. The oarfish ( Regalecus glesne ) is the world’s largest teleost, reaching lengths of 8 m to as much as 12 m. Whole specimen are rare. Whale shark is the largest fish. Most sharks are harmless- at least to humans. Nevertheless, 25 species of sharks are known to have attacked humans, and at least 12 more are suspected of doing so. Three are particularly dangerous- the great white, tiger and bull sharks. Shark jaws display triangular teeth and rows of spears. Each tooth has even small teeth along its edges. It has been estimated that a tiger shark may grow and discard 24,000 teeth in a 10 year period! The whale shark ( Rhiniadon typus ) usually feed by staining plankton from huge mouthfuls of water. It has probably evolved a huge mouth and lost the large teeth of most other sharks not to avoid competition with other sharks but as a specialization for plankton feeding. Pois
