Introduction to List of digestive diseases:
Digestive system is subjected to a number of diseases like caries (tooth decay), mumps (viral disease of parotids), gingivitis (inflammation of gums), tonsillitis (inflammation of tonsils), glossitis (inflammation of tongue), Cholera, amoebic dysentery, worm infection, Typhoid, appendicitis (inflammation of vermiform appendix), colitis (inflammation of colon), piles (excessive dilation of rectal veins), jaundice, vomiting, diarrhea, constipation and indigestion. I like to share this Delocalization of Electrons with you all through my article.
List of digestive diseases:
Jaundice: it is a syndrome caused by excessive presence of bilirubin in blood and its deposition in skin, mucous membranes and sclera. As a result, the patient has a yellow appearance called icterus. Presence of excess of bilirubin is called hyperbilirubinaemia. The urine of the patient appears yellow. The effect is absent in stool which may appear pale. Jaundice can be obstructive (non-flow of bile from liver to duodenum), haemolytic (excessive degradation of erythrocytes), spirochaetal, toxaemic or hepatogenic (due to injury or disease of liver hepatitis). A person suffering from jaundice generally suffers from liver tenderness, nausea, vomiting, fatigue, loss of appetite and fever.
Vomiting: it is forcible exulsion of the contents of stomach through the mouth. During vomiting the cardiac sphincter and oesophagus relax so that a passage way is created from the stomach to the outside. There is contraction of abdominal muscles as well as gastric muscles. Vomiting is controlled by vomiting centre of medulla oblongata. It is commonly preceded by nausea. The agents which promote vomiting are irritating food, irritating or depressive odour, motion sickness, excessive drinking, overeating, early pregnancy, etc.
Diarrhoea: it is excessive frequency and liquidity of faecal discharges. Diarrhoea is caused by viral or bacterial infection of gastrointestinal tract. The common bacteria causing diarrhoea are Escherichia coli, Salmonella, Campylobacter and Shigella. The common diarrhoeal viruses are Rotaviruses and Norwalk viruses. Diarrhoea interferes with digestion. It also reduces the amount of food absorption. Excessive loss of body fluid may result in dehydration. ORS or oral rehydration solution provides protection from dehydration.
Constipation: it is infrequent irregular passage of dry hardened faeces. Constipation may cause injury to digestive tract and produce several complications. It is generally accompanied by headache, feeling of depression, sluggishness and pain in abdomen. The common cause of constipation is reduced roughage content of diet resulting in bowel movement after 2-3 days.
Indigestion: it is inability to properly digest the food. The first symptom of indigestion is abdominal discomfort after meals. There is often distension of stomach and intestine giving a feeling of fullness. A lot of gas or flatus is produced. Indigestion is caused by intolerance to an ingredient of food, defect in stomach or intestine, anxiety, food poisoning, over eating and consumption of spicy food.

Conclusion on list of digestive diseases:
Disorders of digestive system are caused mainly by infection and interfere with the digestion. Deficiency of any nutrient in the food also causes deficiency diseases as marasmus, rickets, osteomalacia, beri-beri, etc.

Plastic Water Storage
Introduction to plastic water storage:
Water is most important thing for survival. Numerous efforts have been made to judiciously use the water by means of publications, training courses, websites and recreation classes. There are many reasons but the main is that without water, human body cannot be lived. So everyone should believe and accept that the storage of water is essential and fundamental for survival. So, water should be at the first priority and we should give the sufficient attention for the storage of water. I like to share this Density of Pure Water with you all through my article.
Water storage ability of plastic:
This should be believed and understood that it is feasible, yet easy for storing water. Many private, public as well as families, and public emergency response organizations have completed great work for storing water for numerous years.
Storage containers of plastic water storage;
Glass containers, plastic containers and metal storage containers are used to store water. There are plastic containers which are very easy to get and use and they are quite cheap, and available in various sizes. Plastic containers are long-lasting and cannot be corroded and broken easily. Due to these reasons, general people go for plastic containers and it is advisable here as well. For using these containers, consideration should be done that which size and type of container should be used. This consideration also includes that how the containers will be used and how they will, or will not, is moved. At the distant location, water is stored in larger and heavier containers which are further transferred into the smaller and easier containers which are able to carry and use. For the easier carrying, we should fill the containers partially full. Containers which contain threads for accommodating spouts or spigots build the life very easier. Please express your views of this topic Power Problems by commenting on blog.
Cautions of plastic water storage:
We should not store the containers near pesticides, gasoline and other chemicals because plastics are permeable to various gases. These chemicals can contaminate the water which is stored in container.
We should not leave the containers empty and should store the water in them.

Atomic Spectra
The emission spectrum of a chemical element or chemical compound is the relative intensity of each frequency of electromagnetic radiation emitted by the element's atoms or the compound's molecules when they are returned to a ground state.
Each element's emission spectrum is unique. Therefore, spectroscopy can be used to identify the elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances
In physics, emission is the process by which energy in the form of a photon is released by a particle, for example, by an atom whose electrons make a transition between two electronic energy levels. The emitted energy is in the form of a photon with a specific frequency. The emittance of an object quantifies how much light is emitted by it. This may be related to other properties of the object through the Stefan–Boltzmann law. For most substances, the amount of emission varies with the temperature and the spectroscopic composition of the object, leading to the appearance of color temperature and emission lines. Precise measurements at many wavelengths allow the identification of a substance via emission spectroscopy.
Origins
When the electrons in the atom are excited, for example by being heated, the additional energy pushes the electrons to higher energy orbits. When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon. The wavelength (or, equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's emission spectrum.

The wavelength (or, equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's emission spectrum.
The fact that only certain colors appear in an element's atomic emission spectrum means that only certain frequencies of light are emitted. Each of these frequencies are related to energy by the formula:
Ephoton = hν,
where E is the energy of the photon, ν is its frequency, and h is Planck's constant. This concludes that only photons having certain energies are emitted by the atom. The principle of the atomic emission spectrum explains the varied colors in neon signs, as well as chemical flame test results mentioned above.
The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level/orbital. When the electron falls back to its ground level the light is emitted.
Electric Field Lines
Introduction on electric field lines:
Scientist Michael Faraday introduced the term electric field in 19 th century. Faraday was born in Newington Butts. Faraday’s perceptions that the pattern of electric field lines characterizing the electric field are invisible in reality. He explained that around a charge particle there a space in which another charge particle experience a force of attraction or repulsion, this region is called the electric field. He gave that electric field lines are vector in nature. I like to share this Electromagnetic Spectrum Wavelength Chart with you all through my article.
Definition of electric field lines:
Electric field lines are the curved or straight paths along which a unit positive charge tends to move in the electric field if it is free to do so. The direction of electric field lines gives the direction of motion of unit positive charge if it is free to do so. The electric field lines are imaginary but they give us the pictorial visualization of electric field. It is useful to draw a pattern of several lines, which extend between infinity and the source charge. These patterns of lines are electric field lines. Electric field lines are also called as electric flux lines. Please express your views of this topic Momentum Problems by commenting on blog.
Properties of electric field lines:
(i) If the electric field is due to isolated charge then the electric field line is always straight.
(ii) If the electric field is due to two or more charges then the electric field line are always straight.
(iii) The electric filed lines are directed away from positive charge and directed towards the negative charge.
(iv) A unit positive test charge tends to move along the electric field line if it is free to do so.
(v) Electric field lines are imaginary lines.
(vi) The tangent at any point to the electric field line gives the direction of electric field at that point.
(vii) Two electric field lines never cross each other.
(viii) If the electric field is stronger in any region then electric field lines are crowded, and the electric filed lines are spread out if the electric field is weaker in any region.
(ix)Electric field lines contracts lengthwise.
(x) Electric field lines cannot pass through the conductor.
(xi)Electric field lines can pass through the non-conductors and dielectrics.

Examples of Physical Properties
Introduction on Examples of Physical Properties:
Physical properties are the properties that can be observed without changing the identity of the substance. In other words,physical properties are the properties which describe a substance without changing its chemical composition. The general properties of matter such as density, colour and hardness and Melting point, boiling point, thermal conductivity, ductility, malleability are also the examples of Physical properties. I like to share this Specific Gravity Formula with you all through my article.
Some Examples of physical properties:
Density
It is a physical property of matter. Each compound and element has its unique density associated with it. In qualitative manner, density is defined as the measure of the relative "heaviness" of objects with a constant volume.
Melting point
Melting point is referred as the temperature at which the solid and liquid states of a pure substance can exist in equilibrium position.If the heat is applied to a solid, its temperature increases till it reaches the melting point. At this temperature, the additional heat converts the solid into liquid without a change in temperature.
Boiling point
The temperature at which a substance changes from liquid state to gaseous state is referred as boiling point.If the pressure of the surrounding gases is decreased, the boiling point of a liquid is lowered. Usually, water will boil at a lower temperature at the top of a mountain, since the atmospheric pressure on the water is less, than it will at sea level, where the pressure is greater. Please express your views of this topic Curie Law by commenting on blog.
Other Examples of Physical Properties
Thermal conductivity
Thermal conductivity is an intrinsic property of a material which has the ability to conduct heat. In general,heat transfer by conduction involves transfer of energy within a material without any motion of the material . In a solid medium, conduction takes place when a temperature gradient exists.
Ductility
Ductility is the property of metal which permits it to be reduced in cross sectional area without fracture. Usually ductile metals show considerable elongation eventually failing by necking, with consequent rapid increase in local stresses during the tensile test.

Laws of Friction
Introduction:
Smooth surfaces are defined by the property that when they are in contact, the surfaces is always perpendicular to their common tangent plane. It can, however, be verified experimentally that no surfaces that are perfectly smooth and that whenever there is a tendency for two bodies which are in contact to move relative to each other, a force known as the force of friction tends to prevent the relative motion. The mathematical discussion of the force of friction that depends on certain assumptions which are embodied in the so called laws of friction and are found to be in close agreement with experiments. I like to share this Equation for Impulse with you all through my article.
Co-efficient friction:
Law 1
When two bodies are in the contact the direction of the forces of Friction on one of them at it's point of contact, is opposite to the direction in which the point of contact tends to move relative to the other.
Law 2
If the bodies are in the equilibrium, the force of Friction is just sufficient to prevent friction and may therefore be determined by applying the conditions of equilibrium of all the forces acting on the body.
Law 3
The ratio of the reducing friction to the Normal reaction between two surfaces depends on the substances of which the surfaces are composed and not on the magnitude of the Normal reaction. This ratio is usually denoted by .
Thus if the Normal reaction is R, the limiting friction is
For given materials polished to the same standard are found to be constant and independent of R. is called The Coefficient of friction. Please express your views of this topic Definition of Electromagnet by commenting on blog.
Basic Laws of friction:
Law 4
The amount of reducing friction is independent of the area of contact between the two surfaces and of the shape of the surfaces, provided that the Normal reaction is unaltered.
Law 5
When motion takes place in the direction of friction is opposite to the direction of relative motion and independent of velocity. The magnitude of the force of friction is a constant ratio to the Normal reaction but this ratio may be slightly less than when the body is just on the point of moving.

Electrical Power Factor
Introduction to electrical power factor:
In a electrical circuit, the power consumed by a load is the product of the voltage across the load and the current passes through the load. But in AC circuits, the voltage and current are in different electrical angles if the load is inductive or capacitive. Is this topic Electric Field Lines hard for you? Watch out for my coming posts.
Therefore, at any point of time, the power consumed by the circuit is the product of the voltage component projected in line with the current direction and the actual current.
The voltage component projected in line with the current direction is the magnitude of the voltage times the cosine of the electrical angle between the voltage and current. The Cosine of this angle is defined as power factor of the load.
Description of Electrical Power Factor
Referring to the above vector diagram, the dot product of V and I (the energy and in turn the power is the dot product of vectors) gives the power P, which is given by,
P = VI cosФ
or P = VI (power factor of the load)
In case of inductive load, the current lags the voltage and in case of capacitive loads the current leads the voltage. This is the reason why the inductive loads are said to have lagging power factors and the capacitive loads are with leading power factors. In case of resistive loads, the angle between the voltage and current is 0. That means the power factor is 1(called as unity power factor). Understanding coulomb's law equation is always challenging for me but thanks to all math help websites to help me out.
Effect of Electrical Power Factor:
We have seen that the power consumed by an inductive load is VI times the power factor or VI times the Cosine of the angle of lag. Since the Cosine of any angle is always less than 1, the power consumed by an inductive load is always less than the power consumed by a resistive load drawing the same current.
Thus, the conductors carry a larger current for a given power in case of lagging power factor.

Elliptical Galaxies
Introduction to elliptical galaxies:
A galaxy is a massive, gravitationally bound system and it consists of stars and stellar remnants, an interstellar medium of gas and dust. An important but poorly understood component of galaxy is tentatively dubbed dark matter. Having problem with formula for celsius to kelvin keep reading my upcoming posts, i will try to help you.
The galaxies are divided into 3 broad classes based on their visual appearance according to Hubble’s scheme as:
Elliptical galaxies
Spiral galaxies
Lenticular galaxies
Elliptical galaxies are smooth, featureless light distributions and appear as ellipses in images.
Spiral galaxies consist of a flattened disk and stars form a two-armed spiral structure with a concentration of stars at the centre is known as the bulge. And it is similar in appearance to an elliptical galaxy.
Lenticular galaxies (designated S0) consist of a bright central bulge which is surrounded by an extended, disk-like structure. These disks have no visible spiral structure and are not actively forming stars in any significant quantity.
Characteristics of Elliptical Galaxies:
An elliptical galaxy is a galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. Elliptical galaxies do not rotate as a whole since they have little or no global angular momentum. The stars orbit the centers of these galaxies, but the orbits are statistically oriented so that only little net orbital angular momentum sums up. An elliptical galaxy contain very little or no interstellar matter, and consist of old population II stars only which appear like luminous bulges of spirals, without a disk component. In elliptical galaxies, the motion of stars is predominantly radial, where as the disks of spiral galaxies, are dominated by rotation. A very little interstellar matter (neither gas nor dust) is observed in elliptical galaxies and it results in low rates of star formation with a few open star clusters and few young stars. Also, elliptical galaxies are dominated by old stellar populations, giving them red colours. Please express your views of this topic Signs of Radiation Poisoning by commenting on blog.
Conclusion to Elliptical Galaxies:
By the Hubble classification system, elliptical galaxies ranges from E0, being nearly spherical, up to E7, which is highly elongated on the basis of their ellipticity. It is believed that many elliptical galaxies are formed due to the interaction of galaxies, resulting in a collision and merger. They grow to enormous sizes and the giant elliptical galaxies are often found near the core of large galaxy clusters. The largest galaxies are known as giant ellipticals. It has been discovered that for some ellipticals, small disk components, and they are one end of a common scheme of galaxy forms which includes the disk galaxies.
