Passage 4 Chemists at the University of Burgos (Spain) have manufactured a sheet that changes colour in the presence of water contaminated with mercury. The result can be seen with the naked eye but when photographing the membrane with a mobile phone the concentration of this extremely toxic metal can be quantified. Mercury contaminations is a problem that is particularly affecting developing countries. It poses a risk to public health since it accumulates in the brain and the kidneys causing long term neurological illnesses. It is emitted from industrial and mining waste, especially small-scale gold mining. A team at the University of Burgos have now developed a technique for detecting the presence of this dangerous metal in water “in a cheap, quick and in situ way,” as explained to SINC by Jose Miguel Garcia, one of the authors of the study. Details have been published in the Analytical Methods journal. Passage 5 There is growing evidence that people with large number of silver fillings are also at risk. It was once believed that mercury bonded so completely with the other metals used in dental amalgam that it would not escape from the filling. We now know this is not true, and in fact the amount of mercury vapor leaving fillings has been measured. Multiple fillings can leak enough mercury into a persons system to cause mercury poisoning. While in the average adult one or two fillings will not cause harm, having multiple fillings can leak enough mercury into a persons system to cause mercury positioning. For women, thera are special health concerns. Mercury crosses the placenta and also passes inti breast milk. Even trace amounts can cause birth defents. Mercury has been linked to regressive disorder, ADHD, development delays and a variety of physical, cognitive and behavioral problems. It has also been linked to intensified PMS (post menstrual syndrome). All of which means that for a woman, especially on in her child bearing years or for a minor , silver fillings can be a serious health hazard. Passage 4 differs from passage 5 in the passage 4 …. A. Gives details on mercury findings B. Discusses mercury specific effects C. Describes dangerous metal in water D. Presents causes of human problems E. Deals with general information on mercury

The coal, oil, and natural gas that drive the industrial world's economy all contain carbon inhaled by plants hundreds of millions of years ago—carbon that now is returning to the atmosphere through smokestacks and exhaust pipes, joining emissions from forest burned to clear land in poorer countries. Carbon dioxide is foremost in an array of gases from human activity that increase the atmosphere's ability to trap heat. (Methane from cattle, rice fields, and landfills, and the chlorofluorocarbons in some refrigerators and air conditioners are others.) Few scientists doubt that this greenhouse warming of the atmosphere is already taking hold. Melting glaciers, earlier springs, and a steady rise in global average temperature are just some of its harbingers. By rights it should be worse. Each year humanity dumps roughly 8.8 billion tons (8 metric tons) of carbon into the atmosphere, 6.5 billion tons (5.9 metric tons) from fossil fuels and 1.5 billion (1.4 metric) from deforestation. But less than half that total, 3.2 billion tons (2.9 metric tons), remains in the atmosphere to warm the planet. Where is the missing carbon? "It's a really major mystery, if you think about it," says Wofsy, an atmospheric scientist at Harvard University. His research site in the Harvard Forest is apparently not the only place where nature is breathing deep and helping save us from ourselves. Forests, grasslands, and the waters of the oceans must be acting as carbon sinks. They steal back roughly half of the carbon dioxide we emit, slowing its buildup in the atmosphere and delaying the effects on climate. The author holds the assumption that ... A. household appliances may pose environmental danger B. carbon dioxide is the only pollutant threate- ning global temperature C. poor countries produce more carbon than that of industrialized countries D. the carbon emitted to the air at present is the same carbon absorbed by plants in the past E. the rate of melting glaciers is proportional with the increasing number of carbon in the air

Infections with Ebola virus are acute. There is not carrier state. Because the natural reservoir of the virus is unknown, the manner in which the virus first appears in a human at the start of an outbreak has not been determined. However, researchers have hypothesized that the first patient becomes infected through contact with an infected animal. After the first case-patient in an outbreak setting is infected, the virus can be transmitted in several ways. People can be exposed to Ebola virus from direct contact with the blood and/or secretions of an infected person. Thus, the virus is often spread through families and friends because they come in close contact with such secretions when caring for infected persons. People can also be exposed to Ebola virus through contact with objects, such as needles, that have been contaminated with infected secretions. Nosocomial transmission refers to the spread of a disease within a health-care setting, such as a clinic or hospital. It occurs frequently during Ebola HF outbreaks. It includes both types of transmission described above. In African health-care facilities, patients are often cared for without the use of a mask, gown, or gloves. Exposure to the virus has occurred when health care workers treated individuals with Ebola HF without wearing these types of protective clothing. In addition, when needles or syringes are used, they may not be of the disposable type, or may not have been sterilized, but only rinsed before reinsertion into multi-use vials of medicine. The part following the passage will likely discuss about .. (A) Directions to carefully exploit the vi- rus for medical purpose. (B) Hints to improve conditions of African health-care facilitie. (C) Details to prevent the occurrence of nosocomial infections. (D) Procedures to sterilize medical equip- ment thoroughly. (E) Ways to locate source of nosocomial transmission.

Passage A It is a standard practice in a hospital setting. Particularly Among western cultures. To separate mothers and their Newborns. Separation is also common for babies under Medicial distress or premature babies, who may be placed in an incubator. Humans are the only mammals who practice such Meaternal-neonate separation, but its physiological impact On the baby has been unknown until now. Researchers Meansured heart rate variability in 2-day-old sleeping Babies for one hour each during skin-to-skin contact with Mother and alone in a cot next to mother's bed. Neonatal Autonomic activity was 176% heigher and quit sleep 86% Lower during maternal separation compared to skin-to-skin Contact. Dr. John Krystal, editor of biological psychiantary. Commanted on the study's findings; "maternal separation Suggest that it is major physiologic stressor for the infant," Thus, as futher evidence emerges, the challenge to doctors Will be to incoporate skin-to-skin contact into routine Treatment whilst still safely providing the other elements of Newborn medical care. Passage B In a study of 29 father-infant pairs, full-term healthy Newborns born by planned cesarean section were Randomized to be placed either skin-to-skin on their father's Chest or beside their father in a crib. The infants in the skin- To-skin group stopped crying and were calmer compared To infants in the crip group. A father should therefore be Regarded as the primary caregiver for the baby when a Mother is not avaible immediately following a birth. Early skin-to-skin contact between a mother and her Baby may need to be limited for practical and medical Safety reasons. "after births complications, mothers Are often not avaible to their habies for contact;" says Principal author kerstin earlandsson. The study shows that A father can soothe his newborn as affectively as a mother, And more effectively than if the baby is placed in a crib During the first two hours after birth. It can be hypothesized that in the future .. a. Premature infants will no longer be separated from their cribs b. Doctors may quest fathers to be ready for skin-to-skin contact. c. Many pregnant women will ask for planned cesarean section. d. The use of neonatal incubators in hospitals will increase. e. The number of stressed newborns will rise significantely.
