Carpentry Before the discovery of metallurgy , long before plastics , the materials that Stone Age man used were those that he found around him in nature : stone , mud , bone , and of course wood. Wood is an extremely important material , having numerous useful properties ; it floats , it burns,   and it can be shaped relatively easily into a variety of different objects. The craft of shaping and using woo-carpentry- has its roots in prehistoric times. Early woodwork consisted of the use of wood for basic tools, but there is also archeological evidence that Neanderthals were shaping wood into new forms as long ago as the middle Paleolithic ( Old Stone Age 300,000 to 30,000 years ago), using tools made from flint and stone. IN this way many useful things were created from wood , including fire-hardened spears and logs hollowed out to create simple boats. By the Neolithic ( New Stone Age ), basic woodworking had evolved into a more complex craft-carpentry. The largely no...

Sickle Cell Diseases             Sickle cell diseases is a group of disorders that affects hemoglobin , the molecule in red blood cells that delivers Oxygen to cells throughout the body  people with this disorder have atypical hemoglobin molecules called hemoglobin S. which can distort red blood cells into a Sickle or crescent shape.             Normally our red blood cell are flexible and round moving easily through our blood vessels. In sickle cell the red blood cell become redyed and sticky and shaped like sickles or crescent moons. These irregular shape cells can get stuck in small blood vessels , which can slow or block blood flow and oxygen to parts of the body.                    Symptoms of sickle cell anemia usually show up at young age . They may appear in babies as early as months old , but generally occurs around the 6 months mark.  ...

Anemia is a medical condition caused by an abnormally low number of red blood cells.Red blood cells , also called erythrocytes, contain hemoglobin ,a red, iron-rich protein that carries oxygen in the blood to the body's tissues. People with anemia develop symptoms caused by the poor delivery of oxygen to their body tissues. These symptoms include pale skin , shortness of breath, rapid heart breath , low vitality  , dizziness and if left untreated , stroke  of heart failure.       There are three primary causes of anemia:         1. Reduced production of red blood cells.             2. Excessive destruction of red blood cells.                 3. Extensive  bleeding  There are moire than 100 types of anemia.

The Indus Valley Civilization was one of the world's first great societies . It developed out of farming and herding communities that carried on the trade with each other . The civilization began to flourish about 4500 years ago and was based in in the vast river plains of what are now Pakistan and northwestern India . There are two main cities - Harappa in the north of Indus Valley , and Mohenjodaro in the south. they were both carefully planned cities and laid out on a grid system.    They had wide road and brick houses , most of which had at least two storeys.
