One oil spill environmental problems]] environmental problems are no chemical or qualitative change in the biological and environmental components Alaahiaúah that this change is outside the field of oscillations of any of these components so as to lead to an imbalance in the balance of nature. Problems associated with environmental pollution, mainly, also known as persistent as any solid, liquid or gaseous, and any microbes or particles lead to the increase or decrease in any of the natural environmental components.

[Edit] Tabieihalmassadr depletion of natural resources: is a set of materials and energy in the environment. Include sources of natural geological sources, ie sources of origin Gioluigi can be extracted from the earth, including:
A forest in California (USA) forests Tabieihmassadr of the most important sources of energy such as oil, coal and oil shale … And others.
XXXXls such as iron, copper, aluminum, lead, zinc, gold, silver and others.
Industrial rocks and include sand, gravel, limestone, granite, gypsum … And others. In addition to groundwater as an important source of life.
Most of the geological sources are the sources of non-renewable (Nonrenewable resources); as the rate of consumption exceeds the rate of formation, with the exception of groundwater for the possibility of recurrence of rain water, and XXXXls are being recycled (Recycling) which can be re-manufactured (industrially renewed). In addition to geothermal energy as a renewable source of energy. And the intervention of these sources in all types of industry that you know, from the tiles and ending with medicine, Registry, lead you use, consists of the sources of geological, electrical appliances, computers and military industries and space vehicles …., all of which come from sources of geological, but we do not understand the relationship between the sources of geological product, which are natural sources of biological resources (Biological Resources) include the wealth of plant and animal, are these sources Renewable (Renewable) the possibility of availability in the environment as a result of regenerating naturally. It also includes natural sources of renewable energy sources (Renewable Energy Resources), such as solar and wind power and energy of water.

Are non-renewable resources depletion in the world, and therefore resorted to the countries of the world to find solutions, such as the development of specific technologies able to use available resources efficiently, and reliance on renewable energy sources.

Are also subjected to the depletion of renewable resources, especially plant and animal, soil and XXXXls, it is caused by consumption of these sources at a rate higher than the rate of natural or artificial regeneration. One of the manifestations of attrition as follows:

Depletion of biodiversity and includes; depletion of vegetation cover, and the depletion of wild animals. Fastnzaf vegetation produced by over-cutting, overgrazing, and pollution, natural disasters, fires, volcanoes, drought, and the depletion of wild animals Vintage by overfishing, pollution and the elimination of wildlife habitat, and others.
To protect the biodiversity of attrition, I turned a lot of countries in the world to the establishment of protected areas for wildlife protection and animal and plant habitats, such as nature reserves, in Jordan there are six reserves administered by the Royal Society for the Protection of Nature RSCN, including reserves: Shaumari and Dana and Mujib, blue and others.
Tree trunk Qtattabaladhafah to pass laws at the local level, such as the Environment Protection Act the Jordan in 1995 and the Law on Environmental Impact Assessment (Environmental impact assessment law) for development projects; The establishment of a project for mining ore is in a certain area, will be subject to this project to the analytical study of the pros and cons to being a approval according to the Law on Environmental Impact Assessment in force in the country.
Distracting sources Tabieihoani inability to recycle XXXXllic mineral products such s copper, iron and other full; any that in each recycling process can not be returned a hundred percent.
Altsahroho set of processes that lead to low productivity of any ecosystem, and produced by natural factors such as the entrapment of rain, high temperature or low, or human-induced, such as overgrazing, deforestation and the continued urban sprawl and the use of different kinds of pollutants. To combat desertification, the text of the Jordanian Environment Protection Act of 1995 to control the sources of soil pollution and control and monitoring of soil erosion and desertification, and to take action to stop this and urban policy based on environmental grounds.
[Edit] Waste Asalbhttrah organisms in the ecosystem of natural residues and their secretions, and the system of environmental re-used efficiently within the course and clear; as the analyzers to analyze raw materials a simple return to the soil Vtstkhaddmha plants, and this is called self-purification. The waste delivered by the human, and as a result of increasing population and rising standard of living and industrial development, agricultural and others, led to increased quantities, in addition to the production qualities dangerous to the environment, making the process of collection, transportation and disposal in all countries of the world are important for the health and the environment. The Law on Environmental Protection to Jordan in 1995 on the definition of solid waste materials as a removable and the owner wishes to get rid of them, so that it is collected, transported and processed in the interest of the community.
[Edit] Main article water pollution: water pollution [edit] water pollutants
Water
Besdo water contaminated with iron. Include the following pollutants:
Waste of oxygen-consuming organisms, including pathogens and organic matter from food and plant waste and crop residues and waste water (domestic, industrial and agricultural). These materials are biodegradable, it can be oxidized in the water, so-called oxygen-consuming materials. Result in consumption of dissolved oxygen in water drained, and thus the death of aquatic strangled, such as fish and microorganisms, the air at the same time increase of micro-organisms anaerobic in the water which analyzes the organic materials anaerobically and produces toxic gases and odors resulting from NH3, H2S.
Organic and toxic substances, including oil, and juice in landfill sites. Water pollution affects the oil-water seas and oceans due to leakage of vessels laden with oil from oil wells or the sea. The juice Vtsab groundwater due to leakage from the landfill and dumps her candidacy through the rocks and then they reach groundwater.
Toxic substances, some of these non-organic material source rocks, as the liberated Baltjoah carry running water to lakes or rivers, or permeate the pores of the soil and rock contaminating groundwater. However, the human accelerated mining and processing operations in the liberation of toxic substances from the rocks at a rate thousands of times compared to natural processes. In addition to adding factories, hospitals, farms, and other toxic substances to the ecosystem.
[Edit] Specifications for the use of potable water Alepeshrataatdmn specifications of water a group of physical properties and chemical and biological weapons. Include the physical properties of color, taste, smell and total dissolved solids (TDS), and suspended solids (TSS), temperature and turbidity, and others. While the chemical properties include; pH (pH) and alkaline and acidic and brackish and dissolved oxygen, and heavy elements, and others. The biological characteristics include the types of microorganisms such as fecal coliforms.

The specifications include the Jordanian drinking water and human uses on the physical properties and chemical and biological weapons. The tables (1-1) and (1-2) some of what is stated in the specifications of Jordan water safe to drink.

[Edit] radioactie contamination
Gaman-ray radiation produced by atomic nuclei are: alpha (α) and beta (β) and gamma (γ); radiation and differ in their ability to penetrate objects, and gamma Volva weakened the most powerful and therefore most dangerous on the bodies of living organisms. And adds to the X-ray radiation (X) which is similar to gamma rays in their effect. And off the radiation from natural sources, including cosmic rays, radiation and the earth’s crust and the self-radiation produced by water, air and food security, such as dairy and i40K i226Ra of food and water, and others. And also produced by human activities, particularly XXXXXXX explosions and XXXXXXX reactor accidents Khadth Chernobyl. Characterized by continuity of radioactive contaminants in the air-term survival in several months, and then fall to the ground and plants, food chains intervened, moving to the bodies of living organisms. The radiation affects living objects from the environment by breathing, accumulate in various organs, especially in the bones, causing disease and then cancer, infertility, and speed of the pyramid.

Taliqalmatar Acid rain is composed of water molecules interacting with carbon dioxide CO2 H2O (l) + CO2 (g) → H2CO3 (aq) acid can then be harder for corals to interact in the water is low concentrations of ions hydronium: 2H2O (l) + H2CO3 ( aq) ⇌ CO32-(aq) + 2H3O + (aq) acid rain caused by gases emitted from factories rights, and has a significant impact on vegetation and on animals and on the front Abannahalamaúah of Lamia, which causes pollution.
[Edit] Aldoibaltlut light pollution discomfort resulting from non-natural lighting at night and the effects of artificial night lighting on fauna and fluorination and the family of fungi and environmental regulations, as well as fixed effects and suspected human health. Tabagtbagtaibgatabata
Like the concept of pollution of the night sky, which is sometimes offset, the conept of a very modern light pollution, as it appeared in the eighties of the twentieth century saw the developments since then.
City of Chicago at night. Chicago Association says statistics for the birds that about 100 million to 1 billion birds die each year because of collision Balbnayat majestic. The impact of this concept appeared jurisprudence astronomers in North America and the Europeans and the organizations that represent them (the French Society of Astronomy in France and in North America Darska …), and other activists, worried about the rapid deterioration of the night environment, ecologists, planners, technicians and energy, doctors, academics, and Alanarien and agencies interested in sustainable development who worked on this new area.
Chicks are attracted to birds such as puffins night lights near the nest. Not last the first attempt to fly has more than 10 seconds and it is threatened with death if not pick up their food from the sea. This explains the survival of the cliffs and isolated islands far from the lighting. Number Alpfon decreasing in Europe. Light pollution is a growing phenomenon of changes functional in ecosystems due to artificial lighting in the environment night and especially the negative impact is clear on the types of animal and plant and fungal task (such as insects, night (butterflies and Ghamdiat wings …) and bats and Albermiat …) even the integrity of the environmental scene in general.
Bio-geographical level, this is a very recent phenomenon. For this reason and due to delayed awareness of this problem and the lack of budgets invested in this area, stay away from this risk control. The effects have not been studied carefully, as it did not include the research but some species especially birds.
[Edit] soil pollution
Different types of Alterbhalterbh (Soil) is a loose surface layer of the earth’s crust which blend with the living organisms and products of decaying matter that exist at a depth of 50 to 100 cm. The soil consists of layers called Handles.
Increasing pollution of water bodies steadily, raising questions about the vulnerability of fish by the pollution and dangerous eating human food of different fish, as well as to raise doubts about the true benefits of this important food source
The city of St. Louis is the annual conference of the American scientific research to support AAAS. In the context of the activities of this conference, a damage of environmental pollution on fish, an important topic for discussion. It is known that the meat of fish may contain Tlut by the seas and oceans on the toxic chemicals such as mercury, for example. If you feed the baby in the womb of the mother to a large amount of this XXXXl, it harms the nervous system and affects the fetus in the worst conditions Balichoh congenital disease and physical disability after birth. But it is also known that fish retain a very small amount of mercury in their bodies, but the monitor foodstuffs U.S. FDA years ago wanted to be cautious and advised pregnant women not to eat fish more than twice per week, in the interest of the health of the fetus.
[Edit] global warming
Points capture the temperature of the Alerdhalaanbas warming is the phenomenon of rising temperature in the environment as a result of a change in the flow of thermal energy and the environment. These are often called this name to the phenomenon of global warming than normal. And the causes of this phenomenon on the ground level of any reason for the phenomenon of global warming is divided scientists to say that this phenomenon is a natural phenomenon and that the Earth’s climate is witnessing a natural periods of hot and chilled cold citing this by the ice or cold somewhat between the 17 century and 18 of Europe. The solar radiation is the main source of energy on the surface of the earth, as it stems from the sun towards the earth is implemented through the gas atmosphere in the form of rays of visible short-wave, and X-ray thermal long-wave (infrared) and certain UV rays that can not be absorbed by ozone, Vimits surface Earth radiation hyphen to Faschen then, and the temperature is broadcast around the atmosphere in the form of near-surface temperature Faihtbs, not allowed to access or Alaavlat to the top, and re-broadcast to the ground, leading to increase the degree of the earth. Is beginning to feel the phenomenon of global warming since 1880, if the earth’s atmosphere warmed by half a degree Celsius over the past century, and will increase one degree Celsius by the year 2040 AD is expected to rise some 3.2 ° C up to the year 2100. Cause of carbon dioxide by about 72% of the global warming almost every year adds the world’s population is about 6 billion of this gas to the atmosphere. Came the term greenhouse of the similarity between what happens in Earth’s atmosphere and what is going on in the greenhouse (plastic) used in agriculture, as the sun beats long waves the walls of these houses Vchea heat in the atmosphere of procedure, where the plant, Fathbs Gerdanha ray thermal short waves and prevent them from dropping out, because they do not Tzmha air to escape from the temperature rises than others.

[Edit] Tsahraltsahr is subjected land degradation in arid and semi-arid and dry sub-humid, leading to the loss of plant life and biodiversity, and lead to the loss of topsoil and loss of the ability of land for agricultural production and support of animal life and human resources. Desertification affects the catastrophic impact on the economic situation of the country, as it leads to a loss of up to $ 40 billion annually in agricultural crops and increase their prices.
Each year the world loses about 691 square kilometers of agricultural land as a result of the process of desertification, while about one third of the globe vulnerable to desertification in general. The impact of desertification on the African continent in particular, where the desert stretches along the north of Africa, almost. It also became extending south as it approached the equator by 60 km than it was 50 years, and in more than 100 country in the world is affected by almost one billion of the total population of the world’s 6 billion people in the process of desertification of their lands; which force them to leave their farms and migrate to cities to earn a living.
Desertification is the phenomenon of geographical animated, acquired the environment in which the properties of desert real, as a result of the ecological balance of natural, with no deterioration, and a wide range in all environments, wetlands, and sub-humid, dry, semi dry, and under the double impact of the changed circumstances shifts natural plant, through the encroachment of the desert steppe region, the encroachment of the territory of steppes towards the territory of the savannah, the encroachment of the savannah region in the territory of the forest.

about the importance of science of the individual and society .. للصف الثامن

The importance of science of the individual and society ..
قال الله تعالى: (اقرأ باسم ربك الذي خلق خلق الإنسان من علق اقرأ وربك الأكرم الذي علم بالقلم علم الإنسان ما لم يعلم )

Thus Allah ordered His Prophet Muhammad, peace be on him and his family and him and the command of Allah to His Messenger ordered him and his nation because it is front of them and their leader to God Almighty and this demonstrates the importance of science and the importance of learning it does not equal who know and those who do not know that the worship of God is not aware of
Like walking in the deserts by ways other than no evidence and this must of everyone to seek knowledge and application of knowledge is obligatory eye on who needs it and the duty enough to those who did not need the slaves of Allah seek knowledge for knowledge is light and guidance, ignorance, darkness and misguidance Seek knowledge it with faith in the elevation in the world and the next it is the legacy of the Prophets peace be upon them that the prophets did not inherit dirhams and dinars, but inherited the knowledge they have inherited the flag is taken may take luck and a multitude of their inheritance, but man is proud, if God be with the knowledge to be an heir to the Messenger of Allah may Allah bless him and his family and him that science better of money and the greatest reward and enduring interest Seek knowledge, let your tongue Believe in others because the implications of science remains after the courtyard of his family Scientists rabbis still monuments commendable and their way Mothorh and their pursuit of commendable and reminded them brought that mentioned in the councils filled councils praise them and pray for them even said good deeds and morality high were role models of people, people in need to scientists more than they need food and drink and the marriage because scientists are the ones who Ydlewnhm the law of God, no life for man, but to do God’s law and scientists to spread the knowledge in various ways, either in council or in writing, either in sermons in mosques and methods of dissemination of science many known that the pursuit of knowledge of the best because it is these high demands, especially in our time which many people when asked the world and the flocking and many where readers knowledgeable without scholars working the fruit of science is to work and the call to God and said the Prophet peace be upon him God we know what benefit us and taught us what Anfna and increased knowledge.

report about shark للصف العاشر

لو سمحتوا اريد report about shark بس بسرعة لان حيل محتاجتة

Introduction:
Sharks (superorder Selachimorpha) are a type of fish with a full cartilaginous skeleton and a highly streamlined body. The earliest known sharks date from more than 420 million years ago.
Since that time, sharks have diversified into 440 species, ranging in size from the small dwarf lanternshark, Etmopterus perryi, a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark, Rhincodon typus, the largest fish, which reaches approximately 12 metres (39 ft 4 in) and which feeds only on plankton, squid, and small fish by filter feeding. Sharks are found in all seas and are common down to depths of 2,000 metres (6,600 ft). They generally do not live in freshwater, with a few exceptions such as the bull shark and the river shark which can live both in seawater and freshwater. They breathe through five to seven gill slits. Sharks have a covering of dermal denticles that protects their skin from damage and parasites, and improves their fluid dynamics so the shark can move faster. They have several sets of replaceable teeth.
Well-known species such as the great white shark, tiger shark, and the hammerhead are apex predators, at the top of the underwater food chain. Their extraordinary skills as predators fascinate and frighten humans, even as their survival is under serious threat from fishing and other human activities.
Subject
Etymology:
Until the 16th century, sharks were known to mariners as "sea dogs".According to the OED the name "shark" first came into use after Sir John Hawkins’ sailors exhibited one in London in 1569 and used the word to refer to the large sharks of the Caribbean Sea, and later as a general term for all sharks. It has also been suggested to be derived from the Yucatec Maya word for shark, xok, pronounced ‘shok’.
Anatomy:
Teeth:
Shark teeth are embedded in the gums rather than directly affixed to the jaw, and are constantly replaced throughout life. Multiple rows of replacement teeth grow in a groove on the inside of the jaw and steadily move forward as in a "conveyor belt"; some sharks lose 30,000 or more teeth in their lifetime. The rate of tooth replacement varies from once every 8–10 days to several months. In most species teeth are replaced one at a time, except in ******cutter sharks the entire row of teeth is replaced simultaneously.
Tooth shape depends on diet: sharks that feed on mollusks and crustaceans have dense flattened teeth for crushing, those that feed on fish have needle-like teeth for gripping, and those that feed on larger prey such as mammals have pointed lower teeth for gripping and triangular upper teeth with serrated edges for cutting. The teeth of plankton-feeders such as the basking shark are smaller and non-functional.
Skeleton
Shark skeletons are very different from those of bony fish and terrestrial vertebrates. Sharks and other cartilaginous fish (skates and rays) have skeletons made of cartilage and connective tissue. Cartilage is flexible and durable, yet has about half the density of bone. This reduces the skeleton’s weight, saving energy. Sharks have no rib cage and therefore on land a shark’s own weight can crush it.
Jaw:
Like its relatives, rays and skates, the shark’s jaw is not attached to the cranium. The jaw’s surface, like the shark’s vertebrae and gill arches, needs extra support due to its heavy exposure to physical stress and its need for strength. It has a layer of tiny hexagonal plates called "tesserae", which are crystal blocks of calcium salts arranged as a mosaic. This gives these areas much of the same strength found in the bony tissue found in other animals.
Generally sharks have only one layer of tesserae, but the jaws of large specimens, such as the bull shark, tiger shark, and the great white shark, have two to three layers or more, depending on body size. The jaws of a large great white shark may have up to five layers. In the rostrum (snout), the cartilage can be spongy and flexible to absorb the power of impacts.
Fins:
Fin skeletons are elongated and supported with soft and unsegmented rays named ceratotrichia, filaments of elastic protein resembling the horny keratin in hair and feathers. Sharks can only drift away from objects directly in front of them because their fins do not allow them to move in the tail-first direction.
Dermal denticles:
Unlike bony fish, sharks have a complex dermal corset made of flexible collagenous fibers and arranged as a helical network surrounding their body. This works as an outer skeleton, providing attachment for their swimming muscles and thus saving energy.[13] In the past, sharkskin has been used as sandpaper. Their dermal teeth give them hydrodynamic advantages as they reduceturbulence when swimming.

Conclusion
Sharks are often killed for shark fin soup. Fishermen capture live sharks, fin them, and dump the finless animal back into the water. Finning involves removing the fin with a hot ****l blade.
Sharks generally reach sexual maturity only after many years and produce few offspring in comparison to other harvested fish. Harvesting sharks before they reproduce severely impacts future populations.
Shark fin has become a major trade within black markets all over the world. Fins sell for about $300/lb in 2022

Overview
.The Sahara’s boundaries are the Atlantic Ocean on the west, the Atlas Mountains and the Mediterranean Sea on the north, the Red Sea and Egypt on the east, and the Sudan and the valley of the Niger River on the south. The Sahara is divided into western Sahara, the central Ahaggar Mountains, the The Sahara divides the continent of Africa into North and Sub-Saharan Africa. The southern border of the Sahara is marked by a band of semiarid savanna called the Sahel; south of the Sahel lies the lusher Sudan and the Congo River Basin. Most of the Sahara consists of rocky hamada; ergs (large sand dunes) form only a minor part.

Geography

A geographical map of Africa, showing the ecological break that defines the Saharan areaThe Sahara covers huge parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia. It is one of three distinct physiographic provinces of the African massive physiographic division.

To the north, the Sahara reaches to the Mediterranean Sea in Egypt and portions of Libya, but in Cyrenaica and the Magreb, the Sahara borders Mediterranean forest, woodland, and scrub ecoregions of northern Africa, which have a Mediterranean climate characterized by a winter rainy season.
To the south, the Sahara is bounded by the Sahel, a belt of dry tropical savanna with a summer rainy season that extends across Africa from east to west. ]

Peoples and languages
The Sahara is home to a number of peoples and languages. Arabic is the most widely spoken language in the Sahara, from the Atlantic to the Red Sea. Berber people are found from western Egypt to Morocco, including the Tuareg pastoralists of the central Sahara. The Beja live in the Red Sea Hills of southeastern Egypt and eastern Sudan. The Arabic, Berber, and Beja languages are part of the Afro-Asiatic language family.

Speakers of the Nilo-Saharan language family also inhabit the Sahara, including the Fur of Darfur in western Sudan and the Saharan languages of Niger, Chad and western Sudan, which includes the Kanuri, Tedaga, and Dazaga.

Introduction
The Sahara Desert, covering most of North Africa, is the largest desert in the world. From north to south the Sahara is between 800 and 1,200 miles and is at least 3,000 miles (4,800 km) from east to west. Due to the massive size of the Sahara, Africa is split into two regions: that which lies above or forms part of the Sahara and the rest of Africa south of the Sahara. On the west, the Sahara is bordered by the Atlantic Ocean and on the east by the Red Sea, and to the north are the Atlas Mountains and Mediterranean Sea.

Physical Features

The Sahara’s topographical features include shallow basins, large oasis depressions, serirs or regs (gravel-covered plains), plateaus, mountains, sand sheets, dunes and sand seas (ergs). The highest part of the desert is at the summit of Mount Koussi, which is 11,204 feet (3,415 m) high. However, the lowest point of the Sahara is 436 feet (133 m) below sea level: in the Qattera Depression in Egypt.

Over 25 percent of the Sahara’s surface is covered by sand sheets and dunes. The most common types of dunes include tied dunes, blowout dunes, barchan and transverse dunes, longitudinal seirfs, and complex sand seas. Within the Sahara are several pyramidal dunes that reach over 500 feet in height while the draa, a mountainous sand ridge, reaches over 1,000 feet. Researchers have for many years tried to figure out how these dunes were formed, but the case remains unsolved.

Animal Life

Some of the mammal species found within the Sahara are the gerbil, jerboa, Cape hare, the desert hedgehog, dorcas gazelle, dama deer, Nubian wild , anubis baboon, spotted hyena, common jackal, sand fox, Libyan striped weasel, and the slender mongoose. The Sahara also contains over 300 species of migratory bird populations along with water and shore birds and various other types of birds. Some of the most common birds are ostriches, raptors, secretary birds, guinea fowl, Nubian bustards, desert eagle and barn owls, sand larks, pale crag martins, and brown-necked and fan-tailed ravens.

[an error occurred while processing this directive] Numerous types of reptiles – including frogs, toads, and crocodiles – can be found within the Sahara’s lakes and pools of water, while lizards, chameleons, skinks, and cobras are to be found among the dunes and rocks.

In this report I`m going to talk about ( Safety ) .
First , I will talk about the safety . Second , I will talk about the Meanings of safety . After that , you will know about the limitation of safety . finally, you are going to know the types of safety . .

|* Safety :

Safety is the state of being "safe", the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. This can take the form of being protected from the event or from exposure to something that causes health or economical losses. It can include protection of people or of possessions.

|* Meanings of safety:

There also are two slightly different meanings of safety, for example, home safety may indicate a building’s ability to protect against external harm events (like weather, home invasion, etc), and the second that its internal installations (like appliances, stairs, etc) are safe (not dangerous or harmful) for its habitants.

Limitations : *|

Safety can be limited in relation to some guarantee or a standard of insurance to the quality and unharmful function of an object or organization. It is used in order to ensure that the object or organization will do only what it is meant to do.
It’s important to realize that safety is relative. Eliminating all risk, if even possible, would be extremely difficult and very expensive. A safe situation is one where risks of injury or property damage are low and manageable.

|* Types of safety :

It is important to distinguish between products that meet standards, that are safe, and those that merely feel safe. The highway safety community uses these terms:
Normative safety :
Normative safety is a term used to describe products or designs that meet applicable design standards.
Substantive safety:
Substantive safety means that the real-world safety history is favorable, whether or not standards are met.
Perceived safety :
Perceived safety refers to the level of comfort of users. For example, traffic signals are perceived as safe, yet under some circumstances, they can increase traffic crashes at an intersection. Traffic roundabouts have a generally favorable safety record, yet often make drivers nervous.

*) conclusion..!

Stress

Stress: Everybody knows what stress is. Stress is an integral part of our urban
lifestyle. It has become a normal part of life, although it is generally known
that stress is bad fo
r health. But, doesn’t stress also have advantages? Is
stress the same as burden?
What is stress?: First of all we want to make clear what exactly stress is. The body’s adaptive response to abnormal circumstances (like threats or demands) from a new or changing situation is called stress. The term "stress" refers both to certain heightened mental and body states and to the causes of such states.
Nowadays the symptoms of stress are well known. When the human body is under stress (whether it is real or imaginary) Adrenaline is poured into the
bloodstream. As a result of that the pulse quickens, the blood pressure raises
and the muscle tension increases. Furthermore you may feel more criticized by others, become more pessimistic, cynical, or resentful than usual. Things you normally look forward to may seem like a burden.
A lot of people are not aware of being under stress. Some are frequently under so much stress that they assume the feeling is normal.
Pros: By hearing the word "stress" most people think of something unpleasant and bad. But that is only conditionally true. Stress has also several positive aspects:
A lot of people (students!) take stress as a replacement for self-discipline.
They just can’t start working without time-pressure. They need to know a
certain date when they must finish their work.. (like students before a test)
It is known, that people work better, faster and more effective under stress.
There are people, who are even more creative under stress! This is because of the height Adrenaline ******* into your bloodstream.
Stress is said to be the best sport doping (Adrenaline). During a sport
activity, Stress encourages and raises the attention / strength. Under stress
the human body is able to do better to do better physical achievements.
Last but not least, some producers of stress (such as physical exercise,
various emotional states, and creative activity) are usually very healthy! But
be careful, continuous high levels of stress are not.
Contras: On the other hand, stress has much more disadvantages than advantages.
Stress is bad for your health! A lot of people react to stress with
aggressiveness, competitiveness, and self-imposed pressure to get things done. This behavior has been linked to increased rates of heart attack, high blood pressure and other diseases. Stress can also affect the immune system, causing the body to be less resistant to a wide range of other health problems.
Most people can’t think clear under stress. They make false decision and work superficial (slapdash). Stress causes reduced concentration ability.
Stress doesn’t only affect you; it also has an effect on your environment. If
you’re under stress and nervous, your (school/work) friends automatically become like you. A stressed person has a bad influence on the work/school atmosphere. A lot of friendships have broken down because of excessive stress.
It is said, that stress is the most common "illness" at the moment. I am not
of the same opinion. As I look at it, everybody reacts different to stress.
While some people become aggressive and nervous, other people may be equally serious in their intentions, but are more patient. So, it is not possible to say, whether stress is good or bad. It just depends on the person.
Furthermore I think that stress is unavoidable nowadays. But if you’re once
under stress, try to manage it the best possible. Why not making stress work for you as a source of energy? Better you use your energies by being creative than wasting them by getting furious.
Signs of Stress: In researching stress, one would learn about what stress is, the early warning signs of stress, the different types of stress, and how to build resistance to it. Stress is a combination of physical, mental, and emotional feelings that result from pressure, worry, and anxiety.
The pressures from stress are called stressors. Some examples of common stressors are: divorce, death in the family, job change, pregnancy, a large mortgage, marriage, and retirement. "In medicine, stress is, a physical, chemical, or emotional development that causes strains that can lead to physical illness." (Microsoft Encarta)
Some of the most common symptoms of stress are emotional distress, muscular problems, and stomach problems. Emotional distress includes anger, irritability, and anxiety. Muscular problems such as tension headaches, upper and lower back pain, and jaw pain (TMJ), are symptoms of stress. Muscular tensions that lead to pulled muscles and tendon and ligament problems, are symptoms of stress as well. Other symptoms of stress are stomach, gut and bowel problems. Heartburn, acid stomach, ulcers, flatulence, diarrhea, constipation, and irritable bowel syndrome are examples of these problems. Symptoms like cold hands or feet, shortness of breath, and chest pain are also common.
The early warning signs of stress include apathy, anxiety, irritability, mental fatigue, and overcompensation or denial. What is stressful for one person, may or may not be stressful for another; each person responds to stress in a different way. A person can plan their life so that stress doesn’t overwhelm them. Managed stress makes people productive and happy.
There are four types of stress. There is acute stress, episodic acute stress, chronic stress, and traumatic stress. Each type of stress has its own characteristics, symptoms, duration, and treatments.
Acute stress is the common type of stress. Acute stress is exciting and thrilling in small amount, but too much is exhausting. Overdoing it on acute stress can lead to psychological distress, tension headaches, upset stomach, and other symptoms. Some examples of stressors that can cause acute stress are: an auto accident that crumpled the car fender; a child’s occasional problems at school; and so on. Acute stress doesn’t have enough time to do extensive damage that is associated with long-term stress.
Episodic Acute stress is what people who suffer from acute stress frequently have. These people’s lives are so disorderly that they are constantly in a state of chaos and crisis. There are always in a hurry, but they are always late. Another form of episodic acute stress comes from no-stop worry. These people tend to be over aroused and tense. The symptoms of episodic acute stress are the symptoms of extended over arousal: persistent tension headaches, migraines, hypertension, chest pain, and heart disease. Suffers are usually very resistant to change of any kind. Acute stress can come up in anyone’s life but it is highly treatable and manageable.
A more serious type of stress is chronic stress. "Chronic stress is the grinding stress that wears people away day after day, year after year." (Battison, 1997 p. 19) It destroys minds, bodies, and lives. Chronic stress comes when a person doesn’t see a way out of a miserable situation. The worst part of chronic stress is that people get used to it and forget that it’s there. Chronic stress kills by means of suicide, violence, heart attack, stroke, and perhaps, even cancer. The symptoms of chronic stress are hard to treat and could require a lot of medical and behavioral treatment, therapy, and stress management
Traumatic stress is a special kind of chronic stress, known as post-traumatic stress disorder (PTSD). It is caused by trauma that is not handled correctly. Some example of traumatic experiences are: accidents, rape, verbal, physical, psychological, or sexual abuse, being in the presence of extreme violence, a brush with death, natural disasters, death of a loved one, and imprisonment. The symptoms of PTSD are flashbacks, over arousal, emotional numbness or loss of feeling, along with extreme emotional outbursts to minor things. People with PTSD suffer from problems with concentration, controlling impulses, and decision making, The long term consequences of PTSD are depression, anxiety, behavioral disorders, multiple personality disorder, and suicide.
There are three basic strategies for dealing with stress. The first strategy is altering situations to make them less stressful. Avoiding stressful situations is the next strategy. Accepting stressful situations is the other basic strategy in dealing with stress at the source. Each strategy has it’s disadvantages and it’s advantages. It’s up to every person to decide which one to use with which situation. "The tougher a person’s resistance to stress is, the more stress they can take." (Hanson, 1985 p.52)
There is a lot a person can do to maximize their resistance to stress. People have resources to help them handle stress. The re resources include family and financial resources, social and spiritual resources, as well as personal resources. They can also develop good health habits and get rid of bad health habits to help build up a resistance to stress. Improving a person’s nutritional habits makes them much less susceptible to stress.
Stress is something that everyone takes on in their day to day lives. It is a part of our daily routines and sometimes builds up to the point where we think it is unbearable. There are many things that cause stress, yet at the same time there are many things that help us relieve it. Stress can cause physical as well as emotional illnesses but it has also been proven that too little stress can be harmful as well. There are many different ways of handling stress. Some are for the goodness of one’s physical well being where as some are for one’s emotional well being. There are even some that help with both. All in all stress seems to occur depending on one9s perception of events, people, and daily things for stress occurs on different occasions for different people.
