Abiogenesis

This new technology meant that old make-up techniques and old products simply would not cut the mustard any more. Every change in texture would now be visible, so it was no longer enough simply to trowel on the slap. New formulations that could seamlessly cover wrinkles and imperfections were therefore developed. Both products use a combination of ingredients with a single goal: It basically bounces light away from the skin, so the shadows and changes in skintone, which is what we see when we look at wrinkles and imperfections, are less obvious. These have a dual role in that they also help to create a smooth, silky texture that glides over the skin. Mica is another key ingredient which works because it also helps to reflect light, creating a look that is natural yet conceas imperfections and evens skin tone. Keen to address this issue is Clinique. However, it also contains a cocktail of antioxidant active ingredients, including Vitamin C, Vitamin E and white birch extract, which have been designed to help break up and, over time, reduce the appearance of uneven skin tone.

Neuroses, or psychoneuroses, are less-serious disorders in which people may experience negative feelings such as anxiety or depression. Their functioning may be significantly impaired, but personality remains relatively intact, the capacity to recognize and objectively evaluate reality is maintained, and they are basically able… Theories An influential view held by the psychoanalytic tradition is that neuroses arise from intrapsychic conflict conflict between different drives, impulses, and motives held within various components of the mind.

Central to psychoanalytic theory, which was founded by Austrian neurologist Sigmund Freud , is the postulated existence of an unconscious part of the mind which, among other functions, acts as a repository for repressed thoughts , feelings, and memories that are disturbing or otherwise unacceptable to the conscious mind.

Abiogenesis: Abiogenesis, the idea that life arose from nonlife more than billion years ago on Earth. Abiogenesis proposes that the first life-forms generated were simple and gradually became increasingly complex. Biogenesis, in which life is derived from the reproduction of other life, was presumably preceded by abiogenesis.

READ MORE Theories An influential view held by the psychoanalytic tradition is that neuroses arise from intrapsychic conflict conflict between different drives, impulses, and motives held within various components of the mind. Central to psychoanalytic theory, which was founded by Austrian neurologist Sigmund Freud , is the postulated existence of an unconscious part of the mind which, among other functions, acts as a repository for repressed thoughts , feelings, and memories that are disturbing or otherwise unacceptable to the conscious mind.

These repressed mental contents are typically sexual or aggressive urges or painful memories of an emotional loss or an unsatisfied longing dating from childhood. Anxiety arises when these unacceptable and repressed drives threaten to enter consciousness ; prompted by anxiety, the conscious part of the mind the ego tries to deflect the emergence into consciousness of the repressed mental contents through the use of defense mechanisms such as repression, denial, or reaction formation.

Neurotic symptoms often begin when a previously impermeable defense mechanism breaks down and a forbidden drive or impulse threatens to enter consciousness. Freud, SigmundSigmund Freud, Freud While the psychoanalytic theory has continued to be influential, another prominent view, associated with behavioral psychology , represents neurosis as a learned, inappropriate response to stress that can be unlearned. A third view, stemming from cognitive theory, emphasizes the way in which maladaptive thinking—such as the fear of possible punishment—promotes an inaccurate perception of the self and surrounding events.

Types Obsessive-compulsive disorders are characterized by the irresistible entry of unwanted ideas, thoughts, or feelings into consciousness or by the need to repeatedly perform ritualistic actions that the sufferer perceives as unnecessary or unwarranted. Obsessive ideas may include recurrent violent or obscene thoughts; compulsive behaviour includes rituals such as repetitive hand washing or door locking.

The drug clomipramine has proved effective in treating many patients with obsessive-compulsive disorders. Somatoform disorders , which include the so-called hysterical, or conversion, neuroses, manifest themselves in physical symptoms, such as blindness, paralysis, or deafness that are not caused by organic disease. In anxiety disorders, anxiety is the principal feature, manifesting itself either in relatively short, acute anxiety attacks or in a chronic sense of nameless dread.

What Are Radioactive Materials? – Definition, Examples, Uses & Benefits

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.

We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.

Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.

Generally, a victim is contacted by someone online through various social media or a legitimate dating website. The victim and the scammer create an online relationship. While the victim may become suspicious overtime, the scammer lures them in with pictures, hardships, promises, excitement, and claims of love. Eventually, the scammer will ask for help, for various reasons, involving the victim sending money.

After the scammer gets all the money they can from the victim, the scammer drops communication, leaving the victim dumbfounded, hurt, confused, and out of a lot of money, which is rarely recovered. I receive a TON of e-mails per year from victims asking for help because they knew I always wanted to be a spy. Unfortunately, by the time the money leaves their hands, it is gone forever.

Usually, these scammers develop fake contacts, using easily obtained pictures from real U. The scammers use internet cafes and reroute money multiple times to untraceable sources, and therefore, their true identity cannot be discovered. This scam has become so popular; there are now online support groups to aid victims in dealing with the emotional and monetary losses incurred with their experience. Does This Sound Familiar?

Form[ edit ] The chacmool is a distinctive form of Mesoamerican sculpture representing a reclining figure with its head facing 90 degrees from the front, leaning on its elbows and supporting a bowl or a disk upon its chest. The figure may be lying on its back or on its side and the abdomen can be sunken below the level of the chest and knees or at the same level. Some chacmools were raised upon rectangular bases. Some of the figures are richly attired whilst others are almost naked. Other materials employed include ceramic and cement.

The name “chacmool” is attributed to Augustus Le Plongeon , who excavated one of the statues at Chichen Itza in

Reproduced in the Senate Report , pg. Freedom of the press, for instance, had little ancestry at common law: In the Colonies, these and similar statutes were likewise enforced and offending religious material was burned in Massachusetts as late as The antiquity of the right is so great that it is all but impossible to document its actual beginning. It is fairly clear that its origin lay in the customs of Germanic tribes, under which arms bearing was a right and a duty of free men; in fact, the ceremony for giving freedom to a slave required that the former slave be presented with the armament of a free man.

These customs were brought into England by the earliest Saxons.

See Article History Abiogenesis, the idea that life arose from nonlife more than 3. Abiogenesis proposes that the first life-forms generated were very simple and through a gradual process became increasingly complex. Although many equate abiogenesis with the archaic theory of spontaneous generation , the two ideas are quite different. According to the latter, complex life e. While the hypothetical process of spontaneous generation was disproved as early as the 17th century and decisively rejected in the 19th century, abiogenesis has been neither proved nor disproved.

Haldane and Russian biochemist Aleksandr Oparin independently set forth similar ideas concerning the conditions required for the origin of life on Earth. Both believed that organic molecules could be formed from abiogenic materials in the presence of an external energy source e. Both also suspected that the first life-forms appeared in the warm, primitive ocean and were heterotrophic obtaining preformed nutrients from the compounds in existence on early Earth rather than autotrophic generating food and nutrients from sunlight or inorganic materials.

Urey and Stanley Miller tested the Oparin-Haldane theory and successfully produced organic molecules from some of the inorganic components thought to have been present on prebiotic Earth. The different components were meant to simulate the primitive ocean, the prebiotic atmosphere, and heat in the form of lightning , respectively.

One week later Miller and Urey found that simple organic molecules, including amino acids the building blocks of proteins , had formed under the simulated conditions of early Earth. Modern conceptions of abiogenesis Modern abiogenesis hypotheses are based largely on the same principles as the Oparin-Haldane theory and the Miller-Urey experiment.

There are, however, subtle differences between the several models that have been set forth to explain the progression from abiogenic molecule to living organism, and explanations differ as to whether complex organic molecules first became self-replicating entities lacking metabolic functions or first became metabolizing protocells that then developed the ability to self-replicate. The habitat for abiogenesis has also been debated.

Radioactive materials are all around us. Some are beneficial, while others may cause us harm. In this lesson you’ll learn what radioactive materials are and explore where they come from and how they can be useful to us. Everything on Earth is made of atoms, but you can see that not everything on Earth is the same. This is because everything is made of different types of atoms called elements.

Is myriad a noun?: Usage Guide Noun Recent criticism of the use of myriad as a noun, both in the plural form myriads and in the phrase a myriad of, seems to reflect a mistaken belief that the word was originally and is still properly only an adjective. As the entries here show, however, the noun is in fact the older form, dating to the 16th century.

The noun myriad has appeared in the works of such writers as Milton plural myriads and Thoreau a myriad of , and it continues to occur frequently in reputable English. There is no reason to avoid it. Noun In English, the “ten thousand” sense of myriad mostly appears in references to Ancient Greece, such as the following from English historian Connop Thirwall’s History of Greece: Myriad can also serve as an adjective meaning “innumerable” “myriad particles”.

While some usage commentators criticize the noun use, it’s been firmly established in English since the 16th century, and in fact is about years older than the adjective. Myriad comes from Greek myrias, which in turn comes from myrioi, meaning “countless” or “ten thousand.

The portico allows entrance to the inside from the exterior and can be found on vernacular and small scale buildings. The loggia is accessed only from inside and intended as a place for leisure. Thus, it is found mainly on noble residences and public buildings. Loggias differ from verandas in that they are more architectural, and, in form, are part of the main edifice in which they are located, while verandas are roofed structures attached on the outside of the main building.

READ MORE Properties, occurrence, and uses Potassium metal is soft and white with a silvery lustre, has a low melting point , and is a good conductor of heat and electricity. Potassium imparts a lavender colour to a flame, and its vapour is green. Potash mine at Esterhazy, Sask. The waste liquors from certain saltworks may contain up to 40 grams per litre of potassium chloride and are used as a source of potassium. K Most potassium is present in igneous rocks, shale, and sediment in minerals such as muscovite and orthoclase feldspar that are insoluble in water; this makes potassium difficult to obtain.

Molten KCl is continuously fed into a packed distillation column while sodium vapour is passed up through the column. Efforts to devise a scheme for commercial electrolytic production of potassium have been unsuccessful because there are few salt additives that can reduce the melting point of potassium chloride to temperatures where electrolysis is efficient. There is little commercial demand for potassium metal itself, and most of it is converted by direct combustion in dry air to potassium superoxide, KO2, which is used in respiratory equipment because it liberates oxygen and removes carbon dioxide and water vapour.

It also can be formed by oxidation of potassium amalgam with dry air or oxygen.
