Mental illness

Mental illness

Mental disorder or mental illness are terms used to refer psychological pattern that occurs in an individual and is usually associated with distress or disability that is not expected as part of normal development or culture.
The recognition and understanding of mental disorders has changed over time.
Categories of diagnoses may include mood disorders, anxiety disorders, psychotic disorders, eating disorders, developmental disorders, personality disorders, and many other categories.
In many cases there is no single accepted or consistent cause of mental disorders, although they are widely understood in terms of a diathesis-stress model and biopsychosocial model.
Mental disorders have been found to be common, with over a third of people in most countries reporting sufficient criteria at some point in their life. There are many different categories of mental disorder, and many different facets of human behavior and personality that can become disordered. The state of anxiety or fear can become disordered, so that it is unusually intense or generalized over a prolonged period of time.
Commonly recognized categories of anxiety disorders include specific phobia, Generalized anxiety disorder, Social Anxiety Disorder, Panic Disorder, Agoraphobia, Obsessive-Compulsive Disorder, Post-traumatic stress disorder.
Relatively long lasting affective states can also become disordered.
Mood disorder involving unusually intense and sustained sadness, melancholia or despair is know as Clinical depression (or Major depression), and may more generally be described as Emotional dysregulation.
Milder but prolonged depression can be diagnosed as dysthymia.
Bipolar disorder involves abnormally "high" or pressured mood states, known as mania or hypomania, alternating with normal or depressed mood.
Whether unipolar and bipolar mood phenomena represent distinct categories of disorder, or whether they usually mix and merge together along a dimension or spectrum of mood, is under debate in the scientific literature. Patterns of belief, language use and perception can become disordered.
Psychotic disorders centrally involving this domain include Schizophrenia and Delusional disorder.
Schizoaffective disorder is a category used for individuals showing aspects of both schizophrenia and affective disorders.
Schizotypy is a category used for individuals showing some of the traits associated with schizophrenia but without meeting cut-off criteria. The fundamental characteristics of a person that influence his or her cognitions, motivations, and behaviors across situations and time - can be seen as disordered due to being abnormally rigid and maladaptive.
Categorical schemes list a number of different personality disorders, such as those classed as eccentric (e.g.
Paranoid personality disorder, Schizoid personality disorder, Schizotypal personality disorder), those described as dramatic or emotional (Antisocial personality disorder, Borderline personality disorder, Histrionic personality disorder, Narcissistic personality disorder) or those seen as fear-related (Avoidant personality disorder, Dependent personality disorder, Obsessive-compulsive personality disorder).

Genetic code

Genetic code

The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells.
Specifically, the code defines a mapping between tri-nucleotide sequences called codons and amino acids; every triplet of nucleotides in a nucleic acid sequence specifies a single amino acid.
Because the vast majority of genes are encoded with exactly the same code, this particular code is often referred to as the canonical or standard genetic code, or simply the genetic code, though in fact there are many variant codes; thus, the canonical genetic code is not universal.
For example, in humans, protein synthesis in mitochondria relies on a genetic code that varies from the canonical code. The genome of an organism is inscribed in DNA, or in some viruses RNA.
The portion of the genome that codes for a protein or an RNA is referred to as a gene.
Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.
Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases.
The purine bases adenine (A) and guanine (G) are larger and consist of two aromatic rings.
The pyrimidine bases cytosine (C) and thymine (T) are smaller and consist of only one aromatic ring.
In the double-helix configuration, two strands of DNA are joined to each other by hydrogen bonds in an arrangement known as base pairing.
These bonds almost always form between an adenine base on one strand and a thymine on the other strand and between a cytosine base on one strand and a guanine base on the other.
This means that the number of A and T residues will be the same in a given double helix as will the number of G and C residues.
In RNA, thymine (T) is replaced by uracil (U), and the deoxyribose is substituted by ribose.

Sleep

Sleep

Sleep is the state of natural rest observed throughout the animal kingdom, in all mammals and birds, and in many reptiles, amphibians, and fish. In humans, other mammals, and many other animals that have been studied — such as fish, birds, ants, and fruit-flies — regular sleep is necessary for survival.
The capability for arousal from sleep is a protective mechanism and also necessary for health and survival. In mammals, the measurement of eye movement during sleep is used to divide sleep into two broad types: rapid eye movement (REM) and non-rapid eye movement (NREM) sleep.
Each type has a distinct set of associated physiological, neurological and psychological features. Sleep proceeds in cycles of REM and NREM phases.
In humans, this cycle is approximately 90 to 110 minutes.
Each phase may have a distinct physiological function.
Drugs such as alcohol and sleeping pills can suppress certain stages of sleep.
This can result in a sleep that exhibits loss of consciousness but does not fulfill its physiological functions. In REM, the brain is active and the body inactive, and this is when most dreaming occurs.
REM sleep is characterized by an electroencephalography (EEG) that has low voltage and mixed frequency, similar in appearance to the wakeful EEG.
During REM sleep there is loss of skeletal muscle tone, and an active sympathetic nervous system. In NREM sleep, the body is active and the brain inactive, and there is relatively little dreaming.
Non-REM encompasses four stages; stages 1 and 2 are considered 'light sleep', and 3 and 4 'deep sleep'.
They are differentiated solely using EEG, unlike REM sleep which is characterized by rapid eye movements and relative absence of muscle tone.
There are often limb movements, and parasomnia sleep walking occurs in non-REM sleep.
A cyclical alternating pattern may sometimes be observed during a stage.

Diabetes

Diabetes

Diabetes mellitus, often simply diabetes, is a syndrome characterized by disordered metabolism and inappropriately high blood sugar (hyperglycemia) resulting from either low levels of the hormone insulin or from abnormal resistance to insulin's effects coupled with inadequate levels of insulin secretion to compensate.
The characteristic symptoms are excessive urine production (polyuria), excessive thirst and increased fluid intake (polydipsia), and blurred vision; these symptoms may be absent if the blood sugar is mildly elevated. Prolonged high blood glucose causes glucose absorption, which leads to changes in the shape of the lenses of the eyes, resulting in vision changes.
Blurred vision is a common complaint leading to a diabetes diagnosis; type 1 should always be suspected in cases of rapid vision change whereas type 2 is generally more gradual, but should still be suspected. The World Health Organization recognizes three main forms of diabetes mellitus: type 1, type 2, and gestational diabetes (occurring during pregnancy), which have similar signs, symptoms, and consequences, but different causes and population distributions.
Ultimately, all forms are due to the beta cells of the pancreas being unable to produce sufficient insulin to prevent hyperglycemia.
Type 1 diabetes is usually due to autoimmune destruction of the pancreatic beta cells, which produce insulin.
Type 2 diabetes is characterized by insulin resistance in target tissues, but some impairment of beta cell function is necessary for its development.
Gestational diabetes is similar to type 2 diabetes, in that it involves insulin resistance; the hormones of pregnancy can cause insulin resistance in women genetically predisposed to developing this condition.

Heart failure

Heart failure

Congestive heart failure (CHF), also called congestive cardiac failure (CCF) or just heart failure, is a condition that can result from any structural or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body.
It is not to be confused with "cessation of heartbeat", which is known as asystole, or with cardiac arrest, which is the cessation of normal cardiac function in the face of heart disease. The symptoms depend largely on the side of the heart which is failing predominantly.
If both sides are functioning inadequately, symptoms and signs from both categories may be present. Given that the left side of the heart pumps blood from the lungs to the organs, failure to do so leads to congestion of the lung veins and symptoms that reflect this, as well as reduced supply of blood to the tissues.
The predominant respiratory symptom is shortness of breath on exertion - or in severe cases at rest - and easy fatigue-ability.
Poor circulation to the body leads to dizziness, confusion and diaphoresis and cool extremities at rest. The right side of the heart pumps blood returned from the tissues to the lungs to exchange carbon dioxide for oxygen.
Hence, failure of the right side leads to congestion of peripheral tissues.
This may lead to peripheral edema or anasarca and nocturia (frequent nighttime urination when the fluid from the legs is returned to the bloodstream).
In more severe cases, ascites (fluid accumulation in the abdominal cavity) and hepatomegaly (painful enlargement of the liver) may develop. The treatment of CHF focuses on treating the symptoms and signs of CHF and preventing the progression of disease.
If there is a reversible cause of the heart failure (e.g.
infection, alcohol ingestion, anemia, thyrotoxicosis, arrhythmia, or hypertension), that should be addressed as well.
Reversible cause treatments can include exercise, eating healthy foods, reduction in salty foods, and abstinence of smoking.

Cancer

Cancer

Cancer is a group of diseases in which cells are aggressive (grow and divide without respect to normal limits), invasive (invade and destroy adjacent tissues), and/or metastatic (spread to other locations in the body).
These three malignant properties of cancers differentiate them from benign tumors, which are self-limited in their growth and do not invade or metastasize (although some benign tumor types are capable of becoming malignant).
Cancer may affect people at all ages, even fetuses, but risk for the more common varieties tends to increase with age.
Cancer causes about 13% of all deaths.
Apart from people, forms of cancer may affect animals and plants. Nearly all cancers are caused by abnormalities in the genetic material of the transformed cells.
These abnormalities may be due to the effects of carcinogens, such as tobacco smoke, radiation, chemicals, or infectious agents.
Other cancer-promoting genetic abnormalities may be randomly acquired through errors in DNA replication, or are inherited, and thus present in all cells from birth.
Complex interactions between carcinogens and the host genome may explain why only some develop cancer after exposure to a known carcinogen.
New aspects of the genetics of cancer pathogenesis, such as DNA methylation, and microRNAs are increasingly being recognized as important. Genetic abnormalities found in cancer typically affect two general classes of genes.
Cancer-promoting oncogenes are often activated in cancer cells, giving those cells new properties, such as hyperactive growth and division, protection against programmed cell death, loss of respect for normal tissue boundaries, and the ability to become established in diverse tissue environments.
Tumor suppressor genes are often inactivated in cancer cells, resulting in the loss of normal functions in those cells, such as accurate DNA replication, control over the cell cycle, orientation and adhesion within tissues, and interaction with protective cells of the immune system. Cancer is usually classified according to the tissue from which the cancerous cells originate, as well as the normal cell type they most resemble.
These are location and histology, respectively.
A definitive diagnosis usually requires the histologic examination of a tissue biopsy specimen by a pathologist, although the initial indication of malignancy can be symptoms or radiographic imaging abnormalities.
Most cancers can be treated and some cured, depending on the specific type, location, and stage.
Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy.
As research develops, treatments are becoming more specific for different varieties of cancer.
There has been significant progress in the development of targeted therapy drugs that act specifically on detectable molecular abnormalities in certain tumors, and which minimize damage to normal cells.
The prognosis of cancer patients is most influenced by the type of cancer, as well as the stage, or extent of the disease.
In addition, histologic grading and the presence of specific molecular markers can also be useful in establishing prognosis, as well as in determining individual treatments.

Stress (medicine)

Stress (medicine)

Stress is a medical term for a wide range of strong external stimuli, both physiological and psychological, which can cause a physiological response called the general adaptation syndrome.
Historically, it was gradually realized that such concepts as anxiety, antagonism, exhaustion, frustration, distress, despair, overwork, pre-menstrual tension, over-focusing, confusion, mourning, and fear could all come together in a general broad term, stress.
The use of the term stress in serious and recognized cases, such as those of post-traumatic stress disorder and psychosomatic illness, has scarcely helped clear analysis of the generalized "stress" phenomenon.
Nonetheless, some varieties of stress from negative life events (distress) and from positive life events (eustress) can clearly have a serious physical impact distinct from the troubles of what psychotherapists call the "worried well." Stress activates the sympathetic branch of the autonomous nervous system and the release of stress hormones including epinephrine, and cortisol. Sympathetic nervous output produces the fight-or-flight response, causing the body to divert bloodflow to large muscles as the body prepares to run away from or fight something.
Less blood flows to the digestive system and other organs that do not assist in fleeing or fighting, producing dry mouth, motor agitation, sweating, pallor, enlarged pupils and over the long term, insomnia.
Modern stressors can cause continual sympathetic nervous system activation with very little opportunity for the parasympathetic nervous system to activate.
When the parasympathetic system is active, the bowel and other non-muscle organs receive good blood-flow, the pupils constrict, and the glands all function well and secrete their various compounds.

Psychology

Psychology

Psychology is both an academic and applied discipline involving the scientific study of mental processes and behavior.
Psychologists study such phenomena as perception, cognition, emotion, personality, behavior, and interpersonal relationships.
Psychology also refers to the application of such knowledge to various spheres of human activity, including issues related to daily life—e.g.
family, education, and work—and the treatment of mental health problems. Psychology is one of the behavioral sciences — a broad field that spans the social and natural sciences.
Psychology attempts to understand the role human behavior plays in social dynamics while incorporating physiological and neurological processes into its conceptions of mental functioning.
Psychology includes many sub-fields of study and application concerned with such areas as human development, sports, health, industry, law, and spirituality. Psychology describes and attempts to explain consciousness, behavior, and social interaction.
Empirical psychology is primarily devoted to describing human experience and behavior as it actually occurs.
Since the 1980s, psychology has begun to examine the relationship between consciousness and the brain or nervous system.
It is still not clear how these interact: does consciousness determine brain states or do brain states determine consciousness - or are both going on in various ways? There are several branches of psychology.
Comparative psychology refers to the study of the behavior and mental life of animals other than human beings.
It is related to disciplines outside of psychology that study animal behavior, such as ethology.
Although the field of psychology is primarily concerned with humans, the behavior and mental processes of animals is also an important part of psychological research, either as a subject in its own right (e.g., animal cognition and ethology), or with strong emphasis about evolutionary links, and somewhat more controversially, as a way of gaining an insight into human psychology by means of comparison or via animal models of emotional and behavior systems as seen in neuroscience of psychology. Personality psychology studies enduring psychological patterns of behavior, thought and emotion, commonly called an individual's personality.
Mainly focusing on the development of the human mind through the life span, developmental psychology seeks to understand how people come to perceive, understand, and act within the world and how these processes change as they age.
This may focus on intellectual, cognitive, neural, social, or moral development.
Quantitative psychology involves the application of mathematical and statistical modeling in psychological research, and the development of statistical methods for analyzing and explaining behavioral data. Psychometrics is the field of psychology concerned with the theory and technique of psychological measurement, which includes the measurement of knowledge, abilities, attitudes, and personality traits.

Wind power

Wind power is the conversion of wind energy into more useful forms, such as electricity, using wind turbines.
At the end of 2006, worldwide capacity of wind-powered generators was 73.9 gigawatts; although it currently produces just over 1% of world-wide electricity use, it accounts for approximately 20% of electricity use in Denmark, 9% in Spain, and 7% in Germany.Globally, wind power generation more than quadrupled between 2000 and 2006. Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator.
In windmills (a much older technology), wind energy is used to turn mechanical machinery to do physical work, such as crushing grain or pumping water. Wind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity to rural residences or grid-isolated locations. Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and greenhouse gas emissions if used to replace fossil-fuel-derived electricity.
The intermittency of wind seldom creates problems when using wind power at low to moderate penetration levels. There are many thousands of wind turbines operating, with a total capacity of 73,904 MW of which Europe accounts for 65% (2006).
The average output of one megawatt of wind power is equivalent to the average electricity consumption of about 250 American households.
Wind power was the most rapidly-growing means of alternative electricity generation at the turn of the century and world wind generation capacity more than quadrupled between 1999 and 2005. There is an estimated 50 to 100 times more wind energy than plant biomass energy available on Earth.
Most of this wind energy can be found at high altitudes where continuous wind speeds of over 160 km/h (100 mph) occur.
Eventually, the wind energy is converted through friction into diffuse heat throughout the Earth's surface and the atmosphere. Large-scale onshore and near-shore wind energy facilities (wind farms) can be controversial due to aesthetic reasons and impact on the local environment. It should be noted, however, that onshore and near-shore studies show that the number of birds killed by wind turbines is negligible compared to the number that die as a result of other human activities such as traffic, hunting, power lines and high-rise buildings and especially the environmental impacts of using non-clean power sources.

How to Recover Data from a Crashed Hard Drive

How to Recover Data from a Crashed Hard Drive

  • Labels:
  •  Today, we will help you how to Recover Data from a Crashed Hard Drive. When your PC switch off suddenly due to any hardware failures or software error problems. If you are regular computer user; you may know that a hard drive failure is an unpredictable situation. It happens very often that your hard drive gets crashed and you ultimately lose you precious saved data and files leading to great discontentment and grief. It's really a worst condition when you are working on an important file or data or picture etc and suddenly everything gets blank and Oh God, your hard disk breaks down. And it becomes even more critical when you don't have any backup installed in your computer at all.

    Though crashing hard drive means total data loss from your computer system but now with the advancements in IT technology, it has become possible to recover your data or file or work when the hard drive stops booting. There are various methods with which you can recover your important data and fix the problem at the ease of your own comfort without waiting for the technician to come. Here I am discussing how to recover your data from a crashed hard drive. Some times your pc may crash due to virus attacks. So in order to avoid such situtatuions you need to secure your pc with good antivirus softwares.


    The first step to be taken for solving the problem is to take out the crashed hard drive from the system. Then install this hard drive in another computer as a secondary drive having Windows installed on it. After it, boot into Windows and install PC Inspector File Recovery. The software is available at free of cost and we provided the download link of the application at the end of the article. But always install it on the primary drive to avoid the over-writing of files you are going to restore. After downloading the PC Inspector File Recovery, open it and select the language. The software is compatible for all windows versions xp/vista/7 and windows 8. A welcome screen will appear with having three options in it:
    Recover deleted files

    This option enables you to restore only those files which have been deleted permanently from your drive and have not been over-written yet.

    Find lost data

    By choosing this option, you will be able to recover the data which has been lost as a result of hard drive crash. With this option, you will further get two more options of "start cluster" and "end cluster". It's better to leave the scanning process of entire drive as it takes a long time depending on the size of your drive.

    Find lost drive

    It is the third option which should be used when you don't see your drive letter in my computer or windows explorer. This option will help you connect the drive and to find your lost data.

    But in the case, if there is no secondary computer to work with, go for the Ultimate Boot CD for Windows. With the help of UBCD, you will be able to boot into Windows which will then run utilities on the damaged drive that will help you solve the issue. With UBCD, you gain an access to various utilities and PC Inspector File Recovery is also one of them which can be run on the system from a CD. For creating UBCD for Windows, you require a PC with Windows XP and XP Installation CD. To keep your crashed hard drive into the freezer is also a successful method to recover the data or files. Download Here

    If all of the above mentioned methods not work, It's time to send your hard drive in the hands of a computer technicians who will use any data recovery tool or apps to help you recover your lost data successfully. However, you may also search for a data recovery software online and get it installed on your computer system.

    Hard drive crash is a common problem that can happen with anybody at any time. So search for the right option and save your precious data and files from getting corrupted.

    Top Ten Tips To Improve System Speed

    The below top ten tips are recommended for any system. It doesn’t matter if you have 256mb RAM or 2 GB RAM. Check the below tips to remove the memory junk and speedup windows os.
    Top 1o tips to improve computer speed
    1. Let your PC boot up completely before opening any applications.

    2. Refresh the desktop after closing any application. This will remove any unused files from the RAM.
    3. Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).
    4. Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM
    5. Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.
    6. Delete the temporary internet files regularly.
    7. Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.
    8. Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.
    9. When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.
    10. Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum.
    RAM IS THE WORKING AREA (DESKTOP) OF THE CPU, KEEP IT AS EMPTY AND UNCLUTTERED AS POSSIBLE!
