Davis Strait, Canada
Some of the greatest depths in the eastern Arctic are reached in the southern end of Davis strait. The surface waters are strongly affected by counterclockwise-flowing currents.
Along the west side, an outflow of cold water from the Arctic Basin moves south, at flow velocities of 8-20 km/day, to feed the Labrador current. On the east side the west Greenland countercurrent brings warmer water north. Ice conditions reflect this flow regime, with heavy ice movement and icebergs along the western shore, contrasting sharply with more open water along the Greenland side.

Manual Scavenging: Nations Shame .
By Sunil Kuksal .
18 December, 2007 .
Combat Law .
The social, cultural and economic realities of modern India unfold a series of paradoxes. While a parliamentary law bans the manual scavenging and the government approves projects to wean the underprivileged section away from this dehumanising occupation, cruel caste apartheid and brutalising poverty perpetuate the practice. Furthermore, neo-liberal economic policies restrict alternative possibilities of having a dignified livelihood. .
The term manual scavenging describes the daily work of manually cleaning and removing human faeces from dry (non-flush) latrines across India. Workers, mostly women and young boys, are also referred to as night soil workers, a Victorian euphemism that hides the repugnance of the word shit. In India, manual scavenging is a caste-based occupation carried out by dalits. The manual scavengers have different caste names in different parts of the country: bhangis in Gujarat, pakhis in Andhra Pradesh, and sikkaliars in Tamil Nadu. These communities are invariably placed at the bottom of caste hierarchy, as well as of dalit sub-caste hierarchy. Using a broom, a tin plate and a drum, they clear and carry human excreta from public and private latrines, more often on their heads, to dumping grounds and disposal sites. Though considered illegal, manual scavenging is forced onto dalits by caste pressure. .
Scavengers earn anywhere between Rs 20 to Rs 160 a month and are exposed to the most virulent forms of viral and bacterial infections that affect their skin, eyes, limbs, respiratory and gastrointestinal systems. Official figures show that there are still 3.43 lakh scavengers in the country. A 2002 report prepared by the International Dalit Solidarity Network, including Human Rights Watch (United States), Navsarjan, (Ahmedabad, Gujarat), and the National Campaign on Dalit Human Rights (NCDHR), gave estimates of one million dalit manual scavengers in India.

TBE300B - AKTA high-speed counter-current chromatography
www.globe-instruments.com/114-TBE300B---AKTA-high-speed-c...
Brief introduction:
TBE300B - AKTA Prime and from Shanghai with field of life, together with ge healthcare of high-speed countercurrent chromatography system, the system consists of TBE - 300 - b and AKTA Prime, is without any solid carrier of liquid-liquid partition chromatography, especially in the separation and purification of active ingredients of natural products has a unique advantage.
Features:
Double channel pump, but the gradient elution, system balance quickly, provide on-line detection, automatic collection;
Three separation column design, double six valve design, form a complete set of automatic collector; www.globe-instruments.com/
The special thermal design concept is adopted in the design of the sand dryer, which eliminates the heat loss of the wind tunnel, increases the heat exchange area and the evaporation intensity per unit volume, has a good energy saving effect, and can greatly improve the drying efficiency of the sand, so that it can be used as soon as possible. So how does it work to complete the drying process?
The sand is sent to the hopper by the belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The inclination of the feeding pipeline should be greater than the natural inclination of the material, so that the material can flow into the sand dryer smoothly.
The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the low end, and is in countercurrent contact with the material, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material runs to the bottom end by gravity. During the forward movement of the wet material in the cylinder, the heat is directly or indirectly supplied by the heat carrier, so that the wet material is dried, and then sent out through a belt conveyor or a screw conveyor at the discharge end.
