Jumeirah Emirates Towers achieves sustainable outcomes rapidly

first_imgJumeirah Emirates Towers was the first hotel in the Jumeirah Group to receive Green Globe Certification. Jumeirah Emirates Towers has been awarded the prestigious and environmentally recognised Green Globe Certification for the 4th consecutive year. Jumeirah Emirates Towers in Dubai graces the city skyline with its stunning architecture. The hotel’s newly refurbished spacious rooms and suites feature state-of-the-art meeting and business facilities making it a popular choice for corporate travellers.Sven Wiedenhaupt, General Manager at Jumeirah Emirates Towers commented, “I am immensely proud of our colleagues’ commitment towards our Corporate Social Responsibility (CSR) and appreciate their initiatives and support in saving utility costs and in turn reducing our carbon footprint.”Green Globe Middle East Preferred Partner, Farnek Middle East LLC, has independently verified the sustainability achievements at Jumeirah Emirates Towers. In line with energy saving initiatives there has been a 1.63% reduction in electricity consumption achieved as compared to the same period in 2013 and 4.17% reduction for gas consumption. Currently approximately 80% of the hotel uses energy efficient lighting and is working towards 100% LED lighting in 2015. Jumeirah Emirates Towers focuses on sustainable outcomes with preference for eco-certified suppliers and biodegradable cleaning products and amenities.last_img read more

The worlds first trees grew by splitting their guts

first_img An artist’s impression of a stand of cladoxylopsida trees, which formed Earth’s first forests. Dr. Chris Berry/Cardiff University The world’s first trees grew by splitting their guts The fossils reveal that, unlike modern trees with a single shaft, cladoxylopsids had multiple xylem columns spaced around the perimeter of a hollow trunk. A network of crisscrossing strands connected the vertical xylem—much like a chain-link fence spreads from pole to pole—and soft tissue filled the spaces between all these strands. New growth formed in rings around each of the xylem columns while an increasing volume of soft tissue forced the strands to spread out.All of this expanded the girth of the trunk, allowing for a taller tree. But it also split apart the tree’s xylem skeleton, which required the tree to continually repair itself, the team reports today in the Proceedings of the National Academy of Sciences. The weight of the tree squeezed tissue at the base of the trunk outward.  Country * Afghanistan Aland Islands Albania Algeria Andorra Angola Anguilla Antarctica Antigua and Barbuda Argentina Armenia Aruba Australia Austria Azerbaijan Bahamas Bahrain Bangladesh Barbados Belarus Belgium Belize Benin Bermuda Bhutan Bolivia, Plurinational State of Bonaire, Sint Eustatius and Saba Bosnia and Herzegovina Botswana Bouvet Island Brazil British Indian Ocean Territory Brunei Darussalam Bulgaria Burkina Faso Burundi Cambodia Cameroon Canada Cape Verde Cayman Islands Central African Republic Chad Chile China Christmas Island Cocos (Keeling) Islands Colombia Comoros Congo Congo, the Democratic Republic of the Cook Islands Costa Rica Cote d’Ivoire Croatia Cuba Curaçao Cyprus Czech Republic Denmark Djibouti Dominica Dominican Republic Ecuador Egypt El Salvador Equatorial Guinea Eritrea Estonia Ethiopia Falkland Islands (Malvinas) Faroe Islands Fiji Finland France French Guiana French Polynesia French Southern Territories Gabon Gambia Georgia Germany Ghana Gibraltar Greece Greenland Grenada Guadeloupe Guatemala Guernsey Guinea Guinea-Bissau Guyana Haiti Heard Island and McDonald Islands Holy See (Vatican City State) Honduras Hungary Iceland India Indonesia Iran, Islamic Republic of Iraq Ireland Isle of Man Israel Italy Jamaica Japan Jersey Jordan Kazakhstan Kenya Kiribati Korea, Democratic People’s Republic of Korea, Republic of Kuwait Kyrgyzstan Lao People’s Democratic Republic Latvia Lebanon Lesotho Liberia Libyan Arab Jamahiriya Liechtenstein Lithuania Luxembourg Macao Macedonia, the former Yugoslav Republic of Madagascar Malawi Malaysia Maldives Mali Malta Martinique Mauritania Mauritius Mayotte Mexico Moldova, Republic of Monaco Mongolia Montenegro Montserrat Morocco Mozambique Myanmar Namibia Nauru Nepal Netherlands New Caledonia New Zealand Nicaragua Niger Nigeria Niue Norfolk Island Norway Oman Pakistan Palestine Panama Papua New Guinea Paraguay Peru Philippines Pitcairn Poland Portugal Qatar Reunion Romania Russian Federation Rwanda Saint Barthélemy Saint Helena, Ascension and Tristan da Cunha Saint Kitts and Nevis Saint Lucia Saint Martin (French part) Saint Pierre and Miquelon Saint Vincent and the Grenadines Samoa San Marino Sao Tome and Principe Saudi Arabia Senegal Serbia Seychelles Sierra Leone Singapore Sint Maarten (Dutch part) Slovakia Slovenia Solomon Islands Somalia South Africa South Georgia and the South Sandwich Islands South Sudan Spain Sri Lanka Sudan Suriname Svalbard and Jan Mayen Swaziland Sweden Switzerland Syrian Arab Republic Taiwan Tajikistan Tanzania, United Republic of Thailand Timor-Leste Togo Tokelau Tonga Trinidad and Tobago Tunisia Turkey Turkmenistan Turks and Caicos Islands Tuvalu Uganda Ukraine United Arab Emirates United Kingdom United States Uruguay Uzbekistan Vanuatu Venezuela, Bolivarian Republic of Vietnam Virgin Islands, British Wallis and Futuna Western Sahara Yemen Zambia Zimbabwe Click to view the privacy policy.

Country Peter Geisen Email Fossilized slices of a 374-million-year-old tree reveal a hollow core surrounded by numerous bundles of woody strands called xylem (the larger black spots), with soft tissue (in gray) between. The smaller black dots are roots. By Dennis NormileOct. 23, 2017 , 3:00 PM Scientists have discovered some of the best preserved specimens of the world’s first trees in a remote region of China. At up to 12 meters tall, these spindly species were topped by a clump of erect branches vaguely resembling modern palm trees and lived a whopping 393 million to 372 million years ago. But the biggest surprise is how they got so big in the first place.Today’s trees grow through a relatively simple mechanism. The trunk is a single cylindrical shaft made up of hundreds of woody strands called xylem, which conduct water from the roots to the branches and leaves. New xylem grow in rings at the periphery of the trunk just behind the bark, adding girth so the tree can get taller.This is not how ancient trees known as cladoxylopsids grew, however. Two specimens discovered in a desert in China’s northwestern Xinjiang province in 2012 were remarkably well preserved. That’s because they underwent a process in which silica—likely emitted by a nearby volcano—saturated the tree and took on the shape of the wood’s internal structure as it decayed, preserving its 3D cellular structure. In the largest of the two fossil trunks, above the bulge, the xylem and soft tissue occupied a ring about 50 centimeters in diameter and 5 centimeters thick, with external roots making up the remainder of the 70-centimeter-diameter tree trunk. The scientists estimate cladoxylopsids could have been 8 to 12 meters tall.This growth strategy has not been seen in any other tree in Earth’s history, says Xu Hong-He, a paleontologist at the Nanjing Institute of Geology and Paleontology in China who discovered the fossilized tree trunks. “It’s crazy that the oldest trees also had the most complex growth strategy,” adds Christopher Berry, a plant paleontologist at Cardiff University in the United Kingdom who helped analyze the fossils.The trees are particularly important, says Berry, because they dominated Earth during the Devonian period from 419 million to 358 million years ago. They formed the first forests and played a key role in absorbing carbon dioxide from the atmosphere. They also added oxygen to the atmosphere, affecting the climate and influencing conditions that fostered the emergence of other life forms, he says. Despite their early critical role in the evolution of life on Earth, the cladoxylopsids do not have any modern descendants. They disappeared at the end of the Devonian period, perhaps because they were left in the shade of taller, more robust trees, or because changing environmental conditions may have favored Archaeopteris, the ancestors of modern trees that appeared about 385 million years ago.The new study is an important step in solving several such mysteries about early Earth, says Brigitte Meyer-Berthaud, a paleobotanist at the University of Montpellier in France who was not involved in the research. To understand the role of cladoxylopsids on our planet’s past, she says, “it is essential to know how the trees are constructed.”last_img read more
