Egypt is one of the oldest countries on earth and the cradle of Mediterranean civilization. The country had occupied the territory in the lower reaches of the Nile River in northeastern Africa. Ancient Egypt was at first narrow valley of the river Nile, which the Egyptians called Hapi, among waterless deserts and bare rocks in northeastern Africa.
However, the soil, due to flooding of the Nile, was one of the worlds most fertile. The Egyptians were awesome people.

Psychologists
have only recently begun to use the term “Facebook addiction“. Before that, there was more generic name for these phenomenon – “Internet addiction.” Today, social networks are gaining increasing popularity. Most often, teenagers and young people under 30 are their most loyal clients. Common interests, the ability to find someone from former classmates or fellow students, or just those who were your childhood friends – all this makes social networks extremely attractive. In addition, through the social networks you can communicate with a lot of buddies at the same time, getting the right information or just having fun.
You have to sound the alarm when a person starts to blur the line between virtual and real world, when the person begins to “live in the network.” The addiction begins to emerge, when virtual friends become closer than real ones, when a Facebook user begins to feel almost physical discomfort, when there is suddenly no Internet connection, when he knows all about the cat of his virtual friend, and does not know that his best friend, who lives next door, had his son born six months ago.

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.

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 »
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 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 »
