Blood is a specialized bodily fluid that delivers necessary substances to the body's cells such as nutrients and oxygen and transports waste products away from cells. In vertebrates, it is composed of blood cells suspended in a liquid called blood plasma. Plasma, which comprises 55% of blood fluid, is mostly water (90% by volume), and contains dissolved proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), platelets and blood cells themselves. The blood cells present in blood are mainly red blood cells (also called RBCs or erythrocytes) and white blood cells, including leukocytes and platelets (also called thrombocytes).[1] The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion. Vertebrate blood is bright-red when its hemoglobin is oxygenated. Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin. Insects and some molluscs use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen as shown in figures 1.1, 1.2 and 1.3[6] Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Arthropods, using hemolymph, have hemocytes as part of their immune system. Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) . In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen. Blood performs many important functions within the body including: - Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells) - Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids) - Removal of waste such as carbon dioxide, urea, and lactic acid - Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies - Coagulation, which is one part of the body's self-repair mechanism - Messenger functions, including the transport of hormones and the signaling of tissue damage - Regulation of body pH (the normal pH of blood is in the range of 7.35 - 7.45) (covering only 0.1 pH unit) - Regulation of core body temperature - Hydraulic functions.

HVAC system:

HVAC (pronounced either ‘H-V-A-C” or “H-VAK”) is an acronym that stands for “Heating, ventilation and air-conditioning.” Often installed into a single system, these three functions of the HVAC system are closely interrelated to provide thermal comfort and to maintain good indoor air quality. HVAC is sometimes referred to as climate control because it provides heating, cooling, humidity control, filtration, fresh air, building pressure control, and comfort control.

All occupied buildings require a supply of outdoor air. Depending on outdoor conditions, the air may need to be heated or cooled before it is distributed into the occupied space. As outdoor air is drawn into the building, indoor air is exhausted or allowed to escape, thus removing air contaminants. Heating, ventilating, and air conditioning is based on the basic principles of thermodynamics, fluid mechanics, and heat transfer, and two inventions and discoveries made by Michael Faraday, Willis Carrier, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and many others. The invention of the components of HVAC systems goes hand-in-hand with the industrial revolution, and new methods of modernization, higher efficiency, and system control are constantly introduced by companies and inventors all over the world.

The term “HVAC system” is used to refer to the equipment that can provide heating, cooling, filtered outdoor air, and humidity control to maintain comfort conditions in a building.

2.3 Building Location

Country: Palestine.

City: Jenin

Elevation: 322 m above sea level Latitude: 32˚.

Building face sits at the North orientation.

The wind speed in Jenin above 5 m/s.

Inside Design Condition:

The name inside design conditions refer to temperature, humidity, air speed and cleanliness of inside air that will induce comfort to occupants of the space at minimum energy consumption. There are several factors that control of selection of the inside design conditions and expenditure of energy to maintain those conditions:

1. The outside design condition.

2. The period of occupancy of the conditional space.

3. The level of activity of the occupants in conditional space.

4. The type of building and its use.

Usually the range of temperature difference between inside and outside is 11 C . the relative humidity range from the conditioned space varies from 30% - 60% . a dry environment will be felt when the relative humidity falls below 30%, and sickness will be felt at relative humidity above 60%.

The Indore air speed is not designed as a parameter for comfort as long as it moves the treated air to the desired corners and edges of the spaces. However, it is desirable to keep it within the range of 0.1 to 0.35 m/s for comfort. In Palestine the inside design condition is:

For winter:

Dry bulb temperature Td =23 C

Relative humidity RH = 50 %

For summer:

The dry bulb temperature Td = 23 C

Relative humidity RH = 50%

Out Side Design Conditions:

Outside design conditions are very important parameters, they must be evaluated correctly since they will determine whether the air conditioning system will provide the desired comfort or not, whether the system will be undersized or oversized. an undersized system will not provide the desired indoor conditions for comfort. an oversized system will cost more than it should for a proper economical engineering system.

Outside design condition vary considerably with the location they are determine by averaging conditions with occur over a number of years, and they generally exclude usually high or low values that are reached for a period of time less than 10 days for the summer and winter seasons.



in Palestine, the outside design conditions are :

For winter:

Dry bulb temperature Td = 6 C

Relative humidity RH = 73 %

For summer:

The dry bulb temperature Td = 31 C

Relative humidity RH = 49%

“People with disabilities have abilities too and that is what this course is all about - making sure those abilities blossom and shine so that all the dreams you have can come true.” [1] Mary McAleese 1951 The Braille system, named after Louis Braille, is a method widely used by blind people enabling them to read and write. Each Braille character, or so called "cell", is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. A dot may be raised at any of the six positions to form sixty-four combinations, counting the space, in which no dots are raised. Braille language is the main language blind adults and kids use. We created a method which can facilitate the reading and writing of Braille language mainly for kids. However, the current Braille systems have many limitations and obstacles such as its size and overlapping the characters ,resulting in difficulties of understanding and applying the language particularly for blind kids and those with low vision. THE NEW BRAILLE READING-WRITING MACHINE principle is based on the classical Braille language. It is considered as an adjuvant method to better understand the Braille language. This device will be used to rise above the limitations of reading and writing in Braille system. The currently used small size characters and the overlap between these characters are the major difficulties the students who lost their sight at old age or people with low vision face with the classical way used in the classical Braille language. Therefore, the machine will enable the blind to write and read at the same time. In addition, it will help the people with low vision by lighting the alphabets to ease reading the language for them. Thus, this device will help blind and low vision students all over the World.
