There are problems that are related to being underweight. Very often being underweight is not the first problem. Rather, it often is the effect of another condition or disease. Unexpected weight loss requires the attention of a doctor. There might be another disease. If that disease is treated, the weight problem also disappears.
Another problem underweight people face is that the weight problem affects their health: Their immune system is weakened, and they may get sick more often. People who are underweight because they cannot get or afford the right food need special attention. Women who are underweight may not have their menstruation and face difficult pregnancies.
Once they were being underweight, psychically, they may feel sad and worried about their health. Therefore, family and friends should support them to help them get rid of their unhappiness.
Etihad Airways
Etihad Airways is one of two major airlines in the United Arab Emirates. It was created by royal decree in July 2003. It started carrying passengers in November 2003. Abu Dhabi, the capital of the United Arab Emirates, is the airline's hub and base of operations. Etihad Airways flies to 63 locations in 42 countries.
Petrol Ofisi
Petrol Ofisi is Turkish petroleum company. It was created in 1941 by Turkey to make gasoline and oil available to the country of Turkey. The government sold the company in July 2000. More than 95% of the company is now owned by Doğan Holding and OMV. The remaining shares of the company are publicly traded stock.
Pot-in-pot refrigerator
The pot-in-pot refrigerator, also known as a Zeer in Arabic, is a food cooling device. It works by using the evaporation of water. It needs no electricity.
It is made by putting a clay pot inside a larger clay pot with wet sand in between the pots and a wet cloth on top. As the water evaporates it cools the inside, letting food stored in the inner pot to be kept fresh for some time. It must be placed in a dry, ventilated place for the water to evaporate to the outside.
Evaporative coolers perform poorly or not at all in climates with high humidity.
Mohammed Bah Abba of Nigeria patented the device in 1995 and was awarded a Rolex prize in 2000 for developing the “pot-in-pot preservation/cooling system”. However, the device was known at least as early as the Middle Kingdom of Egypt, as seen by the hieroglyphic kbb, "to cool".
Earthenware wine coolers work on the same principle. They are soaked in cold water for a while, then emptied and put on the table. The pores of the earthenware are now full of water. Evaporation from the earthenware keeps white wine cool enough for several hours.
Ankylosauridae
The Ankylosauridae are a family of armoured dinosaurs which evolved 125 million years ago and became extinct 65 million years ago during the Cretaceous-Tertiary extinction event. Ankylosauridae and their sister group, the Nodosauridae make up the infraorder Ankylosauria.
They have been found in western North America, Europe and East Asia. Good specimens are rare; most are known only from fragments, and bits of their armour.

Jehol biota
The Jehol biota includes all the living organisms – the ecosystem – of northeastern China between 133 to 120 million years ago (mya). This is the Lower Cretaceous ecosystem which left fossils in the Yixian Formation, some 125–121 mya, and the Jiufotang Formation. It is also believed to have left fossils in the Sinuiju series of North Korea.
The ecosystem in the Lower Cretaceous was dominated by wetlands and numerous lakes (not rivers, deltas, or marine habitats). Rainfall was seasonal, alternating between semi-arid, and mesic conditions. The climate was temperate. The Jehol ecosystem was interrupted at times by ash eruptions from volcanoes to the west. The word "Jehol" was the name given during the Japanese occupation of North-East China, 1933–1946.
The Jehol biota is noteworthy for the many different fossils and the large numbers of individuals of each species that have been recovered.
The biota includes many species that were previously known only from the Upper Jurassic or earlier. These include the dinosaur "Sinosauropteryx", and the pterosaur "Dendrorhynchoides". There was even a primitive protomammal – a tritylodont therapsid – from Lower Cretaceous Japan. Tritylodonts were previously thought to have gone extinct in the Middle Jurassic. The biota also has the earliest and most basal (primitive) known members of groups which spread all around the world by the Upper Cretaceous, including neoceratopsians, therizinosaurs, tyrannosaurs, and oviraptors.
The Jehol biota has produced fossils of plant mega- and microfossils, including the earliest angiosperms, charophytes and dinocysts, snails (gastropods), clams (bivalves), superabundant aquatic arthropods called conchostracans, ostracods, shrimps, insects, spiders, fish, frogs and salamanders, turtles, choristoderes, lizards (squamata), pterosaurs, and dinosaurs including dinobirds, the largest mammals known from the Mesozoic, and a great diversity of birds including the earliest advanced birds, and the smallest and largest birds known from the Mesozoic.
The forests around the lakes were dominated by conifers including members of the podocarp pine, araucaria, and cypress families. There were also ginkgos, bennettitaleans, ephedra, horsetails, ferns, and mosses. The leaves and needles of the trees show adaptations to a dry season, but some of the ferns and mosses are types that grow in very wet habitats. It is possible that the latter avoided dry conditions by growing very close to bodies of water. "Archaefructus" has been described as the earliest known flowering plant (Angiosperm), and it is reconstructed as a water plant.
The fossils have been found in several sites of exceptional preservation. The two most famous are the Yixian and Jiufotang Formations. The Yixian and Jiufotang Formations are "Lagerstatten", meaning that they have exceptionally good conditions for fossil preservation. The fossils are numerous, but also very well preserved. They often have articulated skeletons (bones connected), soft tissues, colour patterns, stomach contents, and twigs with leaves and flowers still attached.
Palaeontologists deduced two things from this. The first is that the land animals and plants were washed into the lakes very gently, or were already in the lakes when they died. They do not show the damage seen in fossils formed by large floods. Second, volcanic ash is commonly interbedded with lake sediments, and ashfalls seem to have quickly buried the fossilized organisms, created anoxic conditions around them, and prevented scavenging.
The biota probably extended as far as North Korea. Its earliest appearance may be in another Chinese lagerstätte, the Huajiying Formation.
