Is it bipolar I or unipolar?
Bipolar Disorder I and II: Hypomania vs. Unipolar Disorder. Bipolar Disorder I is the traditionally diagnosed condition with observable mania and the typical lows of major depression. Bipolar Disorder II refers to a less severe form of bipolar depression with fluctuations between depression and hypomania.
What is bipolar and unipolar?
“Unipolar depression focuses mostly on the depressed mood state rather than the two-pronged presentation of bipolar depression, which includes the movement between the depressive state as well as the expansive or elevated mood state,” explains Lovern Moseley, a licensed psychologist in Boston.

What do you mean by unipolar world?
In the international political system, the unipolar world order is a power distribution in which only one state dominates most of the economic, social, cultural, and military influence over the globe. The unipolar world should not be confused with monarchy or empire.
What is unipolar example?
Some neurons in the vertebrate brain have a unipolar morphology: a notable example is the unipolar brush cell, found in the cerebellum and granule region of the dorsal cochlear nucleus. A third morphological class, bipolar neurons, extend just one axon and dendritic process from the cell body.
What is unipolar and bipolar?
Unipolar depression is another name for major depressive disorder. The term “unipolar” means that this form of depression does not cycle through other mental states, such as mania. In contrast, bipolar conditions cause periods of both depression and mania.
What is a unipolar in physics?
unipolar. 1. (Science: physics) Having, or acting by means of, one pole only. 2. (Science: anatomy) Having but one pole or process; applied to those ganglionic nerve cells which have but one radiating process; opposed to multipolar.
What is unipolar nerve?
A unipolar neuron only has one nerve process extending from the cell body: an axon that extends into dendrites. Unipolar neurons only occur in invertebrates, such as flies, and are not present in humans. In invertebrates, unipolar neurons play a role in the glands and muscles.
Where is the unipolar neuron?
Unipolar neurons are typically sensory neurons with receptors located within the skin, joints, muscles, and internal organs. The axons of such neurons are usually long, terminating in the spinal cord.
What do bipolar mean?
Bipolar disorder (formerly called manic-depressive illness or manic depression) is a mental disorder that causes unusual shifts in mood, energy, activity levels, concentration, and the ability to carry out day-to-day tasks. There are three types of bipolar disorder.
What causes unipolar?
One of the widely accepted theories is that unipolar depression is caused by lack of balance in the naturally occurring chemicals known as neurotransmitters, that are present in the brain as well as the spinal cord.
What is the difference between unipolar bipolar and multipolar?
Multipolar neurons have one axon and many dendrites extending from the cell body. Bipolar neurons have one axon and one dendrite. Unipolar neurons have only one protoplasmic process extending from the cell body. Thus it is the key difference between multipolar bipolar and unipolar neurons.
What is the meaning of unipolar system class 12?
Unipolarity means that there is sole superpower that is dominant in the international system. For example there is unipolarity at present as US is the only superpower. Bipolarity means that there are two superpowers as was the case during the Cold War.
What is unipolar line coding?
Unipolar encoding is a line code. A positive voltage represents a binary 1, and zero volts indicates a binary 0. It is the simplest line code, directly encoding the bitstream, and is analogous to on-off keying in modulation.
What is a multipolar?
Definition of multipolar 1 : having several poles (see pole entry 3) a multipolar generator multipolar mitoses. 2 : having several dendrites multipolar neurons. 3 : characterized by more than two centers of power or interest a multipolar world.
What is unipolar scheme?
Unipolar scheme – In this scheme, all the signal levels are either above or below the axis. Non return to zero (NRZ) – It is unipolar line coding scheme in which positive voltage defines bit 1 and the zero voltage defines bit 0. Signal does not return to zero at the middle of the bit thus it is called NRZ.
What is bipolar line coding?
In telecommunication, bipolar encoding is a type of return-to-zero (RZ) line code, where two nonzero values are used, so that the three values are +, −, and zero. Such a signal is called a duobinary signal. Standard bipolar encodings are designed to be DC-balanced, spending equal amounts of time in the + and − states.
What is bipolar in data communication?
Bipolar signaling, also called bipolar transmission , is a Baseband method of sending binary data over wire or cable. There are two logic states, low and high, represented by the digits 0 and 1 respectively. The illustration below shows a bipolar signal as it might appear on the screen of an oscilloscope.

What is it?
Unipolar depression is another name for major depressive disorder. This mental health condition affects both mental and physical health.
How does it differ from other forms of depression?
The primary difference between unipolar depression and bipolar depression is that a person with unipolar depression experiences only depression rather than cycles of depression and mania, which characterize bipolar disorder, or bipolar depression.
Causes
Major depressive disorder is a complex condition that has genetic, psychological, social, and interpersonal causes. These factors interact with one another to lead to depression. For example, a person may have a genetic predisposition to depression that trauma or stress then activates, triggering symptoms.
Symptoms
Major depression causes a low and depressed mood. A person may experience the world as primarily negative and be subject to cognitive distortions that affect their relationships, work, and school performance.
Treatment
Various antidepressants can effectively treat depression, with the best option depending on several factors. These include:
Outlook
Depression is difficult to treat and often chronic, which means that a person may experience remission and then a relapse.
What is the difference between bipolar and unipolar?
This state is commonly related to behavioural shifts, feelings and the differences that person feel during different stages of treatment. Unipolar disorder is often known as depression whereas bipolar is named as mania.
What is unipolar depression?
It is usually characterised as a continuous feeling of sadness or losing interest in all activities around.
What are the treatments for unipolar depression?
Some of the most common approaches related to this mental disorder are electroconvulsive treatment, antidepressant medications and psychotherapy.
How long does it take for unipolar depression to show results?
But, you will be glad to know that as per the medical professionals, almost 80% of unipolar depression sufferers show positive results towards treatments and it can be observed within 4 to 6 weeks when medication doses are started. Most of the time, professionals use to follow combination of treatments to improve this medical health issue so that fast response can be observed from patient.
Can you treat unipolar depression with talk therapy?
The best thing to know here is that Unipolar Depression is well analysed and understood by the experts in medical community so it is possible to treat this state of mind with talk therapy as well as using few specific medications.
Can you take ECT if you have unipolar disorder?
In case if you are facing troubles or symptoms of unipolar disorder then it is good to take medical assistance as soon as possible. You can find huge information related to unipolar depression over internet and medical professionals can help you to go through several unipolar depression treatment options but the best idea is to go through the solution that suits your lifestyle.
What is the difference between bipolar and unipolar?
The terms, "unipolar" and "bipolar", originated from the type of drivers used to drive stepper motors. In simpler terms, the "uni" in unipolar means "one" and the "bi" in bipolar means "two". The "polar" means electrical and magnetic polarity (FYI: the direction of the current flow determines polarity).
What is bipolar parallel?
Bipolar-Parallel. For the best possible speed and torque characteristics, bipolar-parallel is recommended. This wiring configuration also uses the full coil, so the torque is increased by about 40% compared to unipolar. The inductance is also kept low, which allows the torque to be maintained out to higher speeds.
How many wires are in a bipolar series?
Bipolar-Series (4 or 6 or 8 wires) Bipolar-Parallel (4 or 8 wires) Bipolar Half-Coil (6 or 8 wires) The schematic diagrams below show both the motor winding and driver transistor circuit. Unipolar and Bipolar Half-Coil.
Why are bipolar parallel stepper motors so popular?
Bipolar-parallel stepper motors are becoming more popular due to decreasing costs of driver circuit components. To simplify the wiring, Oriental Motor's are wound internally so there are only four lead wires to connect. Multiple winding options are offered for each frame size and stack length to maximize flexibility in integration to various driver's electrical designs.
Why would a bipolar driver require double the number of transistors than a unipolar driver?
A bipolar driver would require double the number of transistors than a unipolar driver in order to control the current flow in both directions. TIP: Clarification between "Bipolar", "Bipolar-Series", "Bipolar-Parallel"...etc.
Is a stepper motor unipolar or bipolar?
The motor itself is not unipolar or bipolar per se, but manufacturers can classify stepper motors as "unipolar" or "bipolar" according to the number of lead wires. Therefore, a six wire stepper motor can be classified as a "unipolar" motor, and a four wire stepper motor can be classified as a "bipolar" motor.
Can a four wire stepper motor be bipolar?
Four wire stepper motors can be wound for either bipolar-series or bipolar-parallel internally. Motor manufacturers sometimes do not state if a four wire motor is wound for bipolar-series or bipolar-parallel. However, the industry is moving towards bipolar-parallel as the standard for parallel connections for its performance benefits. Another factor is the decreasing cost of the driver.
What is a unipolar world?
A unipolar world essentially is a scenario where most of the world region’s economic, social, cultural aspects are influenced by a single state/country. Just consider the after math of second world war , countries like USA and Russia wanted to prove their mettle in influencing other nations, with their political ideas which is what led to cold war.
What is the meaning of 'unipolarity'?
Unipolarity:#N#Unipolarity in international politics is a distribution of power in which one state exercises most of the cultural, economic and military influence.# N#Characteristics:#N#(1) Unipolarity is an interstate system and not an empire. It implies the existence of many juridically equal nation-states, something that an empire denies.#N#(2) It is an anarchical system. Anarchy results from the incomplete power preponderance of the unipole.#N#(3) This systems possess only one great power and face no competition. If a competitor emerges, the international system is no longer unipolar.
What is a unipolar world?
A unipolar world essentially is a scenario where most of the world region’s economic, social, cultural aspects are influenced by a single state/country.
What is the scenario of a unipolar world?
So if a single country wants to be in that position where it can virtually control other countries, that scenario is unipolar world.
What is the main political, economic, cultural and social vectors of a unipolar world?
It is believed that in a unipolar world the main political, economic, cultural and social vectors are defined by one of the most influential states of the world. Thus, one civilization leads on the highest level, leaving others far behind, but at the same time exerting some influence on the rest of the world.
Why is the Cold War not bipolar?
It is not a bipolar world because there are not two clearly dominant parties. The cold war was a period in world politics characterised by this type
Why is the world order unipolar?
At present world order is uni-polar, because USA is the only present super power.
Is the world unipolar or multipolar?
Almost from the beginning of the nineteenth century to the present day it is common to call the world “unipolar”, “tripolar” or “multipolar”. Such vocabulary is used in the international relations theory — it describes the power balance in the world politics and is the result of various complexly organized hierarchical systems — countries and civilizations. On the one hand the technical progress can be considered as the cause of a structured state and, on the other — population growth, biological and social nature of humans and the existence of people’s desire for communication.
