he planning process is generally aimed at developing the city and making it meet the needs of different citizens. The green areas constitute one of the basic needs of the city and with the rapid and unusual growth in the size of cities, especially in the third world countries, which is often embodied in capitals. Which was achieved as a result of many reasons, including political, economic and social and even enshrined through some of the decisions that were issued and the city of Baghdad, but a clear example of these cities. The city and the environment are inseparable terms. The city is where people spend their lives and their daily experiences, and the environment is the center in which they live. The environment is not an area isolated from actions, aspirations and human needs. It is the sum total and the outcome of all external factors that affect the life of the organism. The environment is a complex dynamic system in which many interactive components are intertwined, and their knowledge of these components, their interactions and the relationships between man and natural resources and his developmental plans have made us realize more than ever that unless development is guided by environmental considerations, development results will be undesirable and return With few benefits or even completely fail. Therefore, we see that the countries, especially the developed ones, have given this aspect a lot of their concerns, but attention to this aspect in Iraq has been and is still below the required level and is reflected in the level of overrun on green areas and indifference to its importance in terms of climatic, aesthetic and environmental ..., by not implementing The plan is the basis for it, but it is overrun. Hence, the choice of Baghdad (the study area) and the problems mentioned previously of a population explosion and the resulting problems as well as the harsh climate that makes the green areas an urgent need to address the harsh conditions experienced by the city. As the problem was exacerbated and complicated and the inability of all the executive authorities to stop the urban encroachment on green areas and reduce abuses. The issue of land uses for urban purposes has faced serious problems in Iraqi cities, especially in Baghdad. Failures have been repeated in implementing the basic plan for the green areas due to ignoring their climatic, environmental, economic and social importance and making decisions that failed to understand the nature of this component. The absence of environmental legislation and the low environmental awareness of these institutions and society in general. Therefore, as planners, we have to recognize the fact that the environment is a moral responsibility that will be borne by all, and that any planning process must take into account the environmental aspects of achieving sustainable development that preserves the right of future generations
The influence of dye laser Rhodamine 6G (R6G) on the molecular structure of silica aerogel prepared by normal drying method is reported. The study also tests the effect of dye concentration on morphological and physical properties. Fourier Transform Infrared Spectroscopy (FTIR) was used to examine this effect, in addition to Field Emission Scanning Electron Microscopy (FESEM), contact angle, and surface area measurement. It was found from FTIR data that the dye laser stays with the inner structure of samples and, at high concentration, it gives a good influence by reducing (OH) band and increasing (CH) band, leading to changing the contact angle from (123á´¼) to (145á´¼). Whereas particle size varied from 22 n

The use of Near-Surface Mounted (NSM) Carbon-Fiber-Reinforced Polymer (CFRP) strips is an efficient technology for increasing flexural and shear strength or for repairing damaged Reinforced Concrete (RC) members. This strengthening method is a promising technology. However, the thin layer of concrete covering the NSM-CFRP strips is not adequate to resist heat effect when directly exposed to a fire or at a high temperature. There is clear evidence that the strength and stiffness of CFRPs severely deteriorate at high temperatures. Therefore, in terms of fire resistance, the NSM technique has a significant defect. Thus, it is very important to develop a set of efficient fire protection systems to overcome these disadvantages. This pape

This study was conducted to determine the effect of different concentrations of ethanol extract of propolis against two fungi Botrytis cinerea, Altrnaria sp. The most important chemical constituents of propolis diagnosed by the Infra Red Spectroscopy, were the Flavonoids specificaly. Results showed a high antifungal activity of ethanol extract of propolis, evidently with a high concentration of extract (5) mg\ml, which completely inhibited the radial growth on both solid and liquid media (PDA &PD Broth ) of both fungi . We observed that , ethanol extract p

Problems of fixed routes appear such that even when they reduce the chance for conflict, they also produce flight paths plans that do not reduce flight time or fuel usage. In nowadays Airlines are heavily overloaded and anxious to minimize the aircrafts fuel usage costs, increase airplanes, and optimize the paths or the flight routes in order to find the most optimal suitable flight paths. This paper presents a new path planning method that deal with such problem effectively, the idea was to produce flights routes
... Show MoreIn this research, we studied the impact of Magnetohydrodynamic (MHD) on Jeffrey fluid with porous channel saturated with temperature-dependent viscosity (TDV). It is obtained on the movement of fluid flow equations by using the method of perturbation technique in terms of number Weissenberg ( ) to get clear formulas for the field of velocity. All the solutions of physical parameters of the Reynolds number , Magnetic parameter , Darcy parameter , Peclet number and are discussed under the different values, as shown in the plots.

ABSTRACT:
Microencapsulation is used to modify and retard drug release as well as to overcome the unpleasant effect
(gastrointestinal disturbances) which are associated with repeated and overdose of ibuprofen per day.
So that, a newly developed method of microencapsulation was utilized (a modified organic method) through a
modification of aqueous colloidal polymer dispersion method using ethylcellulose and sodium alginate coating materials to
prepare a sustained release ibuprofen microcapsules.
The effect of core : wall ratio on the percent yield and encapsulation efficiency of prepared microcapsules was low, whereas
, the release of drug from prepared microcapsules was affected by core: wall ratio ,proportion of coa
