Electrocardiography Research Paper

Electrocardiography is a method of recording and study of the electric fields generated by the heart. Electrocardiography is a relatively inexpensive, but valuable method of electrophysiological diagnostic tool in cardiology.

Electrocardiography is a direct result of electrocardiogram recording – a graphical representation of the potential difference arising from the heart contractions to the body surface. The ECG shows an average of all the vectors of actions that occur at some point in the heart.

In the XIX century, it became clear that the heart produces a certain amount of electricity. First electrocardiograms were recorded by Gabriel Lippmann using a mercury electrometer. The Lippman curves had monophasic character, only remotely resembling modern ECG. Read the rest of this entry »

Research Paper on Baking

Baking is a heat treatment process, including heating food by dry air in an oven. Baking temperature ranges from 160 to 250 ° C.

In the external part of the food, namely the one which is directly subjected to the heat, Maillard compounds are formed as a result of combining a fat (or degradation products thereof) with carbons and proteins. The Mailarda compounds are known for their specific aroma and appearance, however, they are not digested in the human body, and excessive consumption of these may contribute to the development of many diseases, including cancer.

As every heat treatment process, depending on the waveform, backing has certain effects. When baking starts with a low temperature, followed by its gradual rising – the heat will be distributed evenly and slowly. In such case, there can be noted an effect of a great loss of water – a process called drying. Read the rest of this entry »

Vermicomposting Research Paper

Vermicompost is an organic fertilizer, a product of the processing of organic agricultural waste with earthworms (most often Eisenia foetida and Lumbricus rubellus) and bacteria with participation of other organisms (insects, fungi, etc.).

In the process of vermicomposting, weed seeds pass through the worm’s body and lose their ability to germinate. In addition, vermicompost in comparison with manure has reduced content of E. coli, decreased toxicity of heavy metals due to their transition into some sparingly soluble compounds, virtually inaccessible to plants.

Like all organic fertilizer, vermicompost improves the soil structure and its water-physical properties. There is a significant difference between vermicompost and other organic fertilizers – the high content of water-soluble forms of nitrogen, phosphorus, and potassium. Read the rest of this entry »

Research Paper on Augmented Reality

Augmented Reality (AR) refers to different methods to realistically augment reality with virtual objects. Most often, AR is a visual enhancing of the real world by introducing any virtual, imaginary objects in it. AR has numerous applications in various areas: video games, cinematograph, and television, as well as areas related to 3D environmental or 2D graphic design. In addition, AR plays key role in different researches, where simulation is an important part of the process.

The basic technology used in AR today is an image recorded with camera, recognized using algorithms, and enhanced by superimposing virtual imagery on a user’s view of the real world, thus providing a composite view. It offers the possibility of being immersed in a virtual environment with visual, haptic, auditory perceptions in real time. Read the rest of this entry »

Research Paper on Mars

Mars is the fourth planet in order of increasing distance from the Sun and the second by increasing mass and size from the eight planets that make up the solar system. Its distance from the Sun varies between 1.381 and 1.666 AU (206.6 to 249,200,000 km), and its orbital period equals to 686.71 days.

It is a terrestrial planet, such as Mercury, Venus, and Earth. Mars is about ten times less massive than Earth, but is ten times more massive than the Moon. Its topography is similar to both the Moon, with its craters and impact basins, and Earth, with its formation of origin climatic and tectonic such as rift, volcanoes, mesas, valleys, fields of dunes and polar ice caps. On Mars, there are the highest mountain in the solar system, called Olympus Mons and the largest canyon – Valles Marineris.

Mars has now almost null geological activity with only minor events occurring episodically on its surface. You can still observe landslides, rare geysers of CO² in the polar regions, sometimes earthquakes, or rare volcanic eruptions with a small amount of lava. Read the rest of this entry »
