  • Answer:

    There are three primary mechanisms of blending: convection, diffusion, and shear. Convective blending involves gross movement of particles through the mixer either by a force action from a paddle or by gentle tumbling under rotational effects. Diffusion is a slow blending mechanism and will pace a blending process in certain tumbling mixers if proper equipment fill order and method are not utilized. Lastly, the shear mechanism of blending involves thorough incorporation of material passing along forced slip planes in a mixer. Often these mixers will infuse a liquid or powdered binder into the blend components to achieve a special consistency, such as granulates. There are also four main types of mixing and blending equipment: tumbler, convective, hopper, and fluidization.

  • Question: How does a cyclone separator work?

    Posted in: Chemical | Date: 21/12/2017

    Answer:

    Principle and Working: A high speed rotating (air)flow is established within a cylindrical or conical container called a cyclone. Air flows in a spiral pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream and strike the outside wall, falling then to the bottom of the cyclone where they can be removed. In a conical system, as the rotating flow moves towards the narrow end of the cyclone the rotational radius of the stream is reduced, separating smaller and smaller particles. Applications: General applications include: _ oil refineries to separate oils and gases _ cement industry _vacuum cleaners Features Required: High efficiency over a broad flow range Flow-optimized design Low pressure drop resulting in energy savings High safety during operation under pressure Long-term corrosion protection

  • Question: What is a reflex?

    Posted in: Biology | Date: 09/01/2018

    Answer:

    Reflex, or reflex action, is the involuntary movement of any organ or body part that has received a stimulus. It happens without any consciousness and is immediate. Reflexes protect the body from harm.

  • Question: What are the two main types of reflexes?

    Posted in: Biology | Date: 09/01/2018

    Answer:

    Reflex, or reflex action, is the involuntary movement of any organ or body part that has received a stimulus. It happens without any consciousness and is immediate. Reflexes protect the body from harm. The process of the sensory neuron carrying the stimulus to the spinal column and brain, and then the brain sending a message to the motor neuron is called a reflex arc. Reflexes are classified according to the degree of complexity of the neuron (nerve) organization within the reflex arcs. In this classification, there are monosynaptic (or monosegmental) reflexes, which involve only one segment of the central nervous system, and multisynaptic (or intersegmental) reflexes, which involve more than one segment of the central nervous system. Monosynaptic means there is only one neuron involved each way on the path to the spinal cord (called an afferent or sensory neuron) and one away from the spinal cord (called an efferent or motor neuron). An example of a monosynaptic reflex is the patellar (knee jerk) reflex. A multisynaptic reflex, as you can guess, is more complex. In the simplest form, a multisynaptic reflex has more than one neuron (called interneurons) within the reflex arc process. It also involves more than one area of the central nervous system - usually the spinal cord and the brain.

  • Question: What are ganglia?

    Posted in: Biology | Date: 09/01/2018

  • Question: What is the importance of medulla oblongata?

    Posted in: Biology | Date: 09/01/2018

    Answer:

    The medulla oblongata is located in the brain stem, anterior to (in front of) the cerebellum. This is a cone-shaped, neuronal (nerve cell) mass in the hindbrain, which controls a number of autonomic (involuntary) functions. This section of the brain helps transfer messages to the spinal cord and the thalamus, which is in the brain, from the body. The main function of the thalamus is to process information to and from the spinal cord and the cerebellum. The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation. Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla. The medulla oblongata receives its blood supply from several arteries, including the anterior spinal artery, posterior inferior cerebellar artery, and the vertebral artery's direct branches. The medulla contains both myelinated and unmyelinated nerve fibers, also called white matter and gray matter, respectively.

  • Question: What are exocrine and endocrine glands?

    Posted in: Biology | Date: 09/01/2018

    Answer:

    An endocrine gland secretes its products directly into the blood. An example of an endocrine gland is the adrenal gland which secretes adenaline made in the adrenal medulla directly into the blood. An exocrine gland secretes its products into ducts that lead to the target tissue. For example the salivary gland secretes saliva into the collecting duct which leads to the mouth. It's important to note that the pancreas performs both endocrine and exocrine functions. It releases insulin and glucagon directly into the blood (endocrine) and also secretes pancreatic fluid into the pacreatic duct which leads to the duodenum (exocrine).

    Posted in: Biology | Date: 10/01/2018

    Answer:

    4 postulates of Darwinism - 1) .Phenotypic variation- deals with the individual variations amongst organisms' physical traits within the same species. These are differences in characteristics present in individuals of the same generation, that alter their corporal features. 2.)heredity - The second postulate of Darwin's theory details that variations amongst organisms are heritable, meaning individuals can pass them down unto their offsprings. 3) ."struggle for existence," which occurs when there are too many organisms in a population and the available natural resources can no longer support them. Nowadays, this phenomenon is referred to as overpopulation. 4) favorable trait-Darwin also explained how heritable traits can affect organisms' survival and reproductive rates; traits that are favorable to a species are more likely to be passed on to future generations.

  • Answer:

    Answer is C- SO2 and NO2 after oxidation and reaction with water are major contributors to acid rain, because polluted air usually contains particulate matter that catalyse the oxidation. 2SO2 (g) + O2 (g) + 2H2O (l) → 2H2SO4 (aq) 4NO2 (g) + O2 (g)+ 2H2O (l) → 4HNO3 (aq) Ammonium salts are also formed and can be seen as an atmospheric haze (aerosol of fine particles). Aerosol particles of oxides or ammonium salts in rain drops result in wet deposition. SO2 is also absorbed directly on both solid and liquid ground surfaces and is thus deposited as dry-deposition. When acid rain falls and flows as ground water to reach rivers, lakes etc. it affects plants and animal life in aquatic ecosystem. It corrodes water pipes resulting in the leaching of heavy metals such as iron, lead and copper into the drinking water. Acid rain damages buildings and other structures made of stone or metal. The Taj Mahal in India has been affected by acid rain.

  • Question: Help me to write a short note on mountain sickness.

    Posted in: Biology | Date: 15/01/2018

    Answer:

    Mountain sickness 2 types- Altitude sickness or acute mountain sickness, a pathological condition that is caused by acute exposure to low air pressure Chronic mountain sickness, a disease that can develop during extended time living at Altitude. The cause of altitude sickness is the decreasing amount of oxygen available as altitude increases. Symptoms tend to occur within hours after arrival at high altitude and include headache, nausea, shortness of breath and inability to exercise. Medical treatment for altitude sickness may include oxygen, hyperbaric treatment, and medicines such as acetazolamide (Diamox, Diamox Sequels) and/or dexamethasone (AK-Dex, Ocu-Dex) as well as over-the-counter (OTC) pain medications and antinausea medications.

  • Answer:

    When the fossil fuels are burnt in a limited amount of air (oxygen), the products of combustion are CO and H2O. Carbon monoxide is the most dangerous air pollutant. Carbon monoxide when inhaled combines with hemoglobin in the blood to form carboxyhaemoglobin. Carboxyhaemoglobin cannot carry oxygen. This causes a deficiency of oxygen in the tissues resulting in suffocation and even death. It is due to this reason, which it is not advisable to sleep in a closed room with a coal-fired fireplace (Angithi) inside, on a cold wintry night. When the room is closed, no fresh air can enter the room. Initial burning of coal would consume whatever oxygen is the available in the room. Thus, coal/wood would burn in a limited amount of oxygen producing carbon monoxide.

  • Answer:

    Difference of photosynthesis and respiration is that their process is being reversed. In photosynthesis, carbon dioxide and water is yielded to glucose or also known as sugar and oxygen while in respiration, it is the other way around. Sugar and oxygen is yielded to carbon dioxide and water.

  • Answer:

    Respiratory gas exchange and the blood circulation provide a continuous supply of oxygen from the atmosphere to the brain. Inhalation draws in fresh air from the atmosphere into lungs through nostrils and via nasopharynx, and trachea. In the alveoli of the lungs gaseous exchange occurs between blood and the inhaled air. The high PO2 and low PCO2 in the lungs cause diffusion of O2 into the RBCs where it combines loosely with the Fe2+ ions of haemoglobin to form oxyhaemoglobin. When the oxygenated blood reaches in the brain tissue, the lower PO2 and higher PCO2 there causes dissociation of oxyhemoglobin to deoxyhemoglobin (reduced haemoglobin) and molecular oxygen. The brain tissue picks up O2 and releases CO2 to blood.

  • Question: How does the diaphragm help in respiration?

    Posted in: Biology | Date: 15/01/2018

    Answer:

    When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

  • Answer:

    Medulla oblangata. The medulla oblongata basically detects carbon dioxide (CO2) and Oxygen (O2) levels in the bloodstream and determines what changes need to happen in the body.

  • Answer:

    Gaseous exchange at alveoli essentially occurs as a result of diffusion down a concentration gradient. Explanation: The main respiratory surface in humans is the alveoli. Alveoli are tiny balloon like structures with very thin walls. They have numerous tiny thin walled blood vessels in direct contact with them. Inhaled oxygen is able to diffuse into the capillaries from the alveoli while carbon dioxide from the blood diffuses in the opposite direction into the alveoli. Differences in partial pressure of oxygen creates a gradient that causes oxygen to move from the alveoli to the capillaries and into the tissues . Oxygen and carbon dioxide move independently of each other and diffuse down their own concentration gradients. During physical exercise or increased respiration, the body responds by increasing the breathing rate, thus maximising the rate of possible gaseous exchange.

  • Question: What is pneumonia?

    Posted in: Biology | Date: 15/01/2018

    Answer:

    Pneumonia is an infection in one or both lungs. It can be caused by bacteria, viruses, or fungi. Bacterial pneumonia is the most common type in adults. Pneumonia causes inflammation in the air sacs in the lungs, which are called alveoli. The alveoli fill with fluid or pus, making it difficult to breathe.

  • Answer:

    When we breathe in air at sea level, the atmospheric pressure of about 14.7 pounds per square inch (1.04 kg. per cm.2) causes oxygen to easily pass through selectively permeable lung membranes into the blood. At high altitudes, the lower air pressure makes it more difficult for oxygen to enter our vascular systems.

  • Question: Why is light so important in our lives?

    Posted in: Physics | Date: 16/01/2018

    Answer:

    Light is Life. We cannot imagine our life without light. It is the most important factor that influenced the way life evolved on Earth. From photosynthesis, which is responsible for making food in plants to the beautiful world we see and to meeting our energy requirements, the Sun is pivotal to our life. The significance of light is seen in- 1. Food: Photosynthesis is a concept in biology wherein food is synthesized by use of light. Light is the sole source of food generation for all living organisms on the earth. Except for a few chemotrophic bacteria almost all living beings depend on light for their food and energy. 2. For Vitamin D synthesis: Vitamin-D is a type of vitamin which does need to supplied from external source. This is because it can be synthesized from ergosterol and cholesterol by irradiation with sunlight. 3. Vision: All animals, birds are able to see the objects around them due to presence of eyes. But without light these eyes might be absolutely of no us . Because of light, the eyes can receive the image of the objects and send the information to the brain. From this visual information we comprehend the objects. Hence we can notice that in darkness we could see nothing. So light makes us able to see objects around. 4. Colors: This whole world looks beautiful due to colors. But in darkness we see no colors. This is because all the colors in this world are possible only due to light. The light has many spectra. Each spectra has a color and these are broadly referred as VIBGYOR. 5. Maintenance of temperature: Light is a form of energy. And sunlight has huge energy by which the temperature on the earth is maintained. Due to this, the life exists on the earth. 6. Maintains Body clock or circadian rhythm : Everyday light keeps plants and animals ticking with time.There is a clock inside both plants and animals which keep them active during day and relaxed at night. This clock is controlled by light. 7. Drying and evaporation: Sunlight helps in drying of soil, forests, air and rocky surfaces due to its ability to heat up. Also it helps water evaporate from oceans and water ponds. 8. Sterilization: Light especially it ultra violet component is a good sterilizing agent.

  • Question: What are the differences between larynx and pharynx?

    Posted in: Biology | Date: 16/01/2018

    Answer:

    Pharynx is a part of alimentary canal present at the back of buccal cavity. The pharynx is the common channel for food and air. When you swallow food, a flap-like valve called the epiglottis closes the windpipe. Epiglottis prevents the entry of food particles into respiratory tract. Larynx is the part of respiratory system which connects inferior part of pharynx with trachea. It holds vocal cords and is responsible in producing voice.It plays main role in the processes like swallowing and breathing. Larynx is a small voice box which connects the pharynx and the trachea (wind pipe).

  • Question: How does the light help us to see?

    Posted in: Physics | Date: 16/01/2018

    Answer:

    The visual ability of humans and other animals is the result of the complex interaction of light, eyes and brain. We are able to see because light from an object can move through space and reach our eyes. Once light reaches our eyes, signals are sent to our brain, and our brain deciphers the information in order to detect the appearance, location and movement of the objects we are sighting at. The whole process, as complex as it is, would not be possible if it were not for the presence of light. Without light, there would be no sight.
