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.

Building Details:

Information Technology and Engineering College is consist of four floors, There are different applications inside the Building as the table (1) shows.

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%

HVAC (pronounced either "H-V-A-C" or "aitch-vak") is an acronym that stands for the closely related functions of "Heating, Ventilating, and Air Conditioning"- the technology of indoor environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers). HVAC is particularly important in the design of medium to large industrial and office buildings such as skyscrapers and in marine environments such as aquariums, where safe and healthy building conditions are regulated with temperature and humidity, as well as "fresh air" from outdoors. Background The invention of the components of HVAC systems went 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 three central functions of heating, ventilating, and air-conditioning are interrelated, providing thermal comfort, acceptable indoor air quality, within reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces. How air is delivered to, and removed from spaces is known as room air distribution.[1] In modern buildings the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally "size" and select HVAC systems and equipment. For larger buildings, building services designers and engineers, such as mechanical, architectural, or building services engineers analyze, design, and specify the HVAC systems, and specialty mechanical contractors build and commission them. Building permits and code-compliance inspections of the installations are normally required for all sizes of buildings.[citation needed] The HVAC industry is a worldwide enterprise, with career opportunities including operation and maintenance, system design and construction, equipment manufacturing and sales, and in education and research. The HVAC industry had been historically regulated by the manufacturers of HVAC equipment, but Regulating and Standards organizations such as HARDI, ASHRAE, SMACNA, ACCA, Uniform Mechanical Code, International Mechanical Code, and AMCA have been established to support the industry and encourage high standards and achievement

“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.

Wastewater treatment is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. The sun creates its energy through a thermonuclear process that converts about 650,000,0001 tons of hydrogen to helium every second. The process creates heat and electromagnetic radiation. The heat remains in the sun and is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation (including visible light, infra-red light, and ultra-violet radiation) streams out into space in all directions. A solar still operates on the same principle as rainwater: evaporation and condensation. The water from the oceans evaporates, only to cool, condense, and return to earth as rain. When the water evaporates, it removes only pure water and leaves all contaminants behind. Solar stills mimic this natural process . Solar still has a top cover made of glass, with an interior surface made of a waterproof membrane. This interior surface uses a blackened material to improve absorption of the sun's rays. Parabolic trough technology is used to produce heat to replace conventional energy used to heat water and air, to generate steam and to produce air-conditioning.Below is an explanation of the concept of parabolic trough solar collectors, factors that influence their design and the practicality and usefulness of the technology to meet a wide range of energy requirements. The parts of the trough system and its working: • The parabolic trough reflector: The cylindrical parabolic reflector reflects incident sunlight from its surface onto the receiver at the focus point. Typically, the reflector is made of thick glass silver mirrors formed into the shape of a parabola. Alternatively, mirrors can be made from thin glass, plastic films or polished metals. • The receiver tube or heat collection element: The receiver tube consists of a metal absorber surrounded by a glass envelope. The absorber is coated with a selective coating to maximize energy collection and to minimize heat loss. The glass envelope is used to insulate the absorber from heat loss, and is typically coated with an anti-reflective surface to increase the transmittance of light through the glass to the absorber. For high temperature CSP applications, the space between the absorber and glass tube is evacuated to form a vacuum

In this study the possibility of using waste heat to operate a small size air cooling device was investigated. Such devices are proposed to be used in automobile air conditioning systems that utilize either the rejected heat from the exhaust gases or the engine cooling water. Two different alternatives of heat exchanger types was proposed, they are: air-water system, and water-water system. The last type was used due to small surface areas. The designed absorption Refrigeration cycle uses LiBr2-watre pair as the working fluid. The proposed device was designed and constructed successfully using the proper metals. The main components were: evaporator, generator, condenser, absorber, and tow expansion valves. Many difficulties were faced during the operation of the device as result of the operating conditions since such cooling systems working pressure is 91 kPa vacuums. It was difficult to operate the cycle continually due the failure of the used pump under deep vacuum pressure. As a result the cycle was operated discontinuously and a 2oC temperature drop in the cooled water was observed for a single cycle operation for cold water flow rate of 0.0254 kg/s. It was concluded that such cooling device needs special type of throttling valves that work under very small pressure drop and vacuum conditions. Moreover the locations of the input and output lines from each component should be selected carefully to sure good self regulating level control of the liquid.

The bread industry has since ancient times, it can not dispense with the bread, is the most

important source of food , the bread industry has evolved, and started making bread by putting

metal flat plate on the fire and then putting dough above it, It then became a profession .

There are two types of bakeries, semi-automatic and full- automatic, by semi-automatic

bakeries each process separate from the other as the mixture process is making without respect to

other as well as cutter, rounder and etc, on the other hand, by full-automatic bakeries each

process is making with respect to other by sensors system.

A bakery consists of several parts (Dough mixing, Cutting, Rounding, Rolling and

Baking). In our project we focus only on the design on an oven for baking of bread.

This oven will be dedicated for Arab bread of a diameter of 15 cm to accommodate 14

loaves which must stay in the oven for a period ranging from 60 seconds to 80 second, at a





=7854 kg/m³

We chose bread oven project because of two reasons:

1) Bread ovens in the Palestinian market was manufactured by blacksmiths who do not

have the scientific skills in engineering design and production, which may be one reason for the

poor in thermal efficiency of the furnace, which reduces the profits to the owners of these ovens

and bread prices becomes more and more. For this reason we decide to make the development of

our society that increase the Palestinian furnace efficiency to save the energy and increase the

profits of ovens owners.

2) Palestinian countryside of Palestinian society used to make bread by primitive methods

and the kind of hardship, they plant wheat fields for this purpose, in our oven we will decrease

the size and material used to achieve a cheep family oven which withstand the need of the

Palestinian villages homes, small markets and restaurants, This furnace produces 81.3 kg of

bread in one hour

The main objective in this project is to make insure MATLAB codes that will be formed as a complete program that will record a voice command which specified in the four chosen words (GO, STOP, BACK, LEFT) and analyzing it then recognize it , then that will send a suitable code into parallel port (LPT1) at will be a command suitable for the spoken word this command will control the robotic car which communicated with computer by the radio waves.





This p1oject consists of three main parts which can be simplified as following:



1- Software: that will record the signal and make suitable processing on it.





2- Wireless communication: link to transfer the command from the computer to the robotic car.





3- Hardware: This can be summarized in the robotic car

Palestine is considered a poor country in the sources of fossil fuel (power), nowadays this fossil power prices are escalating to unprecedented levels, which is not affordable by our economy especially that the demand on this type of power is increasing, in other words the prices of oil is expected to go higher & higher…….. which our citizens can not withstand ,



As long as Palestine is a sunny country, the most suitable solution for our poverty in fossil fuel is to look for the means that allow us to utilize the free power of the sun. Upon the studies conducted on solar power it is noticed how huge is the quantity of unutilized solar power, as a result of our negligence to this vital & free source of power. Compared to the other projects which were built to utilize the solar power, our project is:-





1. Applicable: it is easy to manufacture, the raw material used to fabricate it is

available & it needs no operators.





2. Efficient: the incident rays of the sun remain perpendicular on the plate (panel) all the day over, which actually means that the output power is the highest attained.





3. Low running cost: because the operation cost is merely negligible.





For the above mentioned justifications we believe that our project is practical & cheap. We hope that the university will adopt it one of the leading projects that its students have created.

DESIGN_OF_MEDICAL_WASTE_INCINERTOR_INTEGRATED_WITH_DEASINLATION.doc

In Palestine Medical waste is one of the most important environmental problems that are facing Palestinian national authority (PNA) in the last few years.



The disposal of garbage and medical waste is a problem that continues to grow with the development of industrialized nations and the growth of population. Since the beginning of the people have needed to find a way of disposing of the trash. In 18th century England and France, carters were paid by individuals to carry trash and discard it on the outskirts of town. Disposal in open pits became routine and Benjamin Franklin initiated the first municipal cleaning program in Philadelphia in 1757. Since then we have come a long way and have developed types of waste that cannot simply be dumped into a hole.



The purpose of this study was first, to study the construction of incinerator integrated with distillation water for Nablus city. Second, increase awareness about Mechanical and thermal design.



The results of the study reveal that:

1. The total Quantities product from Nablus hospitals approximately 810Kg/day.

2. There is no heat recovery system attached with medical incinerators in Palestine.

3. The study also shows that the heat product from the medical incinerator can be used to produce distillate water at flow rate of 900kg/hr
