الخلاصة

The speech act of 'greeting' is one type of the expressive speech acts which reflect the psychological states of the speakers specified in the propositional contents. Each speaker may find himself/herself tending to express pleasure many times daily at meeting or seeing a hearer. Therefore, 'greeting' is one of the expressive acts mostly used in our daily life. The present research aims at: 1. Examining the theoretical views adopted by linguists, philosophers and researchers concerning: a. Definitions, classifications, types(forms and formulas)and strategies of the speech act of 'greeting'. b.The defining properties that reflect its nature and main social function,i.e.,identifying separate cultures. c.The semantic, the syntactic and the pragmatic structures of greeting. 2.Arriving at different and to some extent new theoretical views from those presented for discussion especially those concerned with the social function and the pragmatic structures of the speech act of 'greeting'.

Most securities available for investment have uncertain outcomes and are thus risky. The basic problem facing each investor is to determine which particular risky securities to own. Because a portfolio is a collection of securities, this problem is equivalent to the investor selecting the optimal portfolio from a set of possible portfolios. Hence, this situation is often referred to as the portfolio selection problem. Many trails were to find solution to this problem, begins with the complicated ideas of Markowitz, passing through the contributions of Tobin, Sharpe, & Lintner, and ending with the most modern simplification approaches. Markowitz's ideas are led to derivation of efficient frontier subject to a set of the extreme assumptions, especially in the respect to short selling & riskless lending and borrowing. Thus, this paper is aimed to derive the efficient frontier subject to a different original extreme & most reality alternative assumptions. This paper is reached to many conclusions, most important among them is that an efficient frontier takes a different shapes subject to the different assumptions in the respect of investors' ability to sell short & to riskless lending and borrowing. The set of efficient portfolio opportunities available for investor is expanded when allowed for him to exercise short selling and his efficient frontier takes a concave curve shape with open upper end in contrast to the Markowitz's efficient frontier curve with both ends closed (minimum variance portfolio – maximum return portfolio). Adding of riskless asset to the components of investor's portfolio is represent a new opportunities expanding the feasible set significantly and, more important, changes the location & shape of substantial part of Markowitz's efficient frontier. The paper is approached to many recommendations, most important among them is necessity to educate the investors' population, in the Iraqi stock exchange, about the real shape of their efficient frontier which they faced in their environment.

When denture is worn in the mouth for considerable period of time, it will become colonized with microorganisms and causing denture stomatitis, it is commonly found in the maxillary arch, rarely in the mandibular arch, and it is not uncommon under removable partial denture base in the maxillary arch. Denture trauma, allergy, poor oral hygiene, PH level of saliva, age, sex, smoking and immune system deficiency are generally regarded as etiological factors in denture stomatitis .The significant causes of denture stomatitis are trauma and infection with Candida species .The most important predisposing factor for Candida induced denture stomatitis is the presence of denture or any appliances in the oral cavity, indirectly, this has been proved since removal of the denture will cause the infection to disappear. Prosthetic treatments include removal of dentures, lining of dentures, making new denture and disinfection of dentures. In this study mixed Nystatin and Fluconozale (antifungal agent) with acrylic resin and evaluated the effect of these materials on some mechanical properties (hardness strength & impact strength). This study was clearly shown that statistically non significant differences in shore hardness strength of Fluconozale group and Nystatin group, and highly significant difference in impact strength of Fluconozale group and Nystatin group when compared with control groups .This mean the Fluconozale & Nystatin less effect on hardness strength, but more effect on impact strength.

الخلاصة

Back ground: The polymethyl methacrylate (PMMA) polymer is the most popular dental resin for denture base in dentistry since many years. Rough surface are likely to occur unavoidably during the construction of a dental appliance. An acrylic denture base may exhibit minor surface roughness which needs to be removed before the denture to be polished, this roughness if not removed it will effects the mechanical properties of denture base and render it more dental plaque and satin retainer eventually less hygienic. Aims of the study: In present study we examined the effect of denture cleanser on the surface roughness of heat-cure polymerized acrylic denture base resin. Material and method: (50) specimens of pink heat-cure acrylic resin were prepared with dimensions of (65 mm x10 mm x 3 mm) length, width and depth respectively according to ADA specifications 1975. The specimens were divided into (2) groups: control group consist of (25) specimens socked in distilled water and experimental group consist of (25) specimens socked in denture cleanser (protefix active ) about 15 minutes for (14) days.The surface roughness measured by (Talysurf 4). Results: The results showed a significant differences at (P < 0.05), as compared with control group. Conclusion: it can be concluded that the surface roughness of acrylic denture base increased with the frequent used of denture cleansers.

Obesity refers to body mass index (BMI) greater than 30 kg/ m2. This study was conducted on the 44 obese subjects their biomass index over than 30 and 27 non-obese healthy control. Parameter assessed were (BMI) weight in kg / hight2 in meter, lipid profile, and albumin. The results revealed that there are highly significant increase (p<0.001) in concentration of cholesterol, triglycerides, LDL and VLDL and significantly increased (p<0.01) in concentration of HDL comparing with the control. In addition albumin concentration was non significant difference (p>0.05) comparing with the control. The statistical analysis demonstrated that there wasn’t significant difference (p>0.05) in lipid profile and albumin concentration between male and female but there was highly significant increase (p< 0.001) in female BMI comparing with male. When the subjects were classified into two groups depending on associated diseases, the result showed that there was highly significant increased (p<0.0001) in concentration of cholesterol, triglycerides and VLDL in obese subjects with diseases (57%) comparing with healthy obese subjects (43%). Also there was significant increase (p<0.05) in concentration of HDL and albumin in obese subjects with diseases when comparing with healthy obese, Whereas LDL concentration was significantly increased (p<0.01). In contrast when classified the subjects according to their age, group1 (18-40) year and group2 (41-80) year. The results appear that there were no significant differences (p>0.05) in concentration of lipid profile and albumin between these groups.

The antioxidant activity of methanol water extract (20:80, v/v) of the leaves of Myrtus communis L. was checked, using the - carotene spray method, and measuring the coupled oxidation of - carotene and linoleic acid. The genetic analysis was carried out depending on DNA fragmentation test of WBCS of albino swiss mice (Balb/c) after exposuring to the extract of the concentrations 0.001 , 0.005 and 0.01 mg/100 l of cell pellet. The results showed that there is activity of the antioxidant in the extract through the appearance of 3 positive bands on thin layer chromatography, that kept the yellow colour of - carotene (Rf=0.87. 0.97 and 0.98). This activity was confirmed by the ability of the extract to keep the absorbance relatively stable( max=470nm) through the period of 105 min. and close to the positive control curve of butylated hydroxy toluene. The genetic analysis results showed that the concentration of 0.001 mg/ 100 l of cell pellet was ineffective on the DNA of WBCS of mice, while the concentrations of 0.005 and 0.01 mg/100 l caused DNA fragmentation , these were cleared from the appearance of DNA smears with molecular sizes ranged between 20-2 and 18-0.4 kbp, respectively.

Background: post-traumatic stress disorder (PTSD) is the characteristic symptoms following the psychological traumatic event which is generally outside the range of usual human experience. These involve: re-experiencing the traumatic event, numbing of responsiveness to or reduced involvement with human external world and a variety of autonomic, dysphoric or cognitive symptoms. Objectives: to estimate the presenting symptoms of PTSD in Iraqi patients. Methods: this is a cross sectional study that enrolled 140 patients with PTSD who had been attended the outpatient clinic of psychiatric unit at Al-Diwaniyah Teaching Hospital during period between the 1st of March 2009 -1 AUGUST 2009. PTSD diagnosed according to criteria of structural clinical interview for diagnostic and statistical manual of mental disorder text revision (DSM-IV-TR). Result: this study revealed that 100% patients having PTSD. This is consistent with the conditions found in the DSM-IV-TR. The study also referred to symptoms of accompanying neurotic disorders in the individuals of the sample, such as depressive symptoms (73%), enduring personality changes (59%), generalized anxiety disorder (56%), and adjustment disorder (48%). Delayed form of PTSD was found in 54% of patients. 95 patient out of 140 patient had wish to seek help. Conclusions: this study proved that the associated disorders, as depression or anxiety, may overlap diagnosis PTSD. The study proved that the symptom of PTSD increased in percentage in the Iraqi patients due to exposing them to three wars, economic embargo, and the present state of terrorism; so it became a problem that needs care and attention of the specialists, and the cooperation of different governmental establishments and civil society organizations.

This paper presents an attempt to study and analysis of an existing practical case of power factor correction for an 11 kV industrial distribution network in the Baghdad Region in the State of Iraq. The industrial power distribution networks of the State of Iraq and, also, in any country in the world, would have inductive loads at low power factor. One of the best solutions for the problem of low power factor or lagging current problem is commonly done by connecting shunt VAR compensation elements such as shunt capacitors bank or local capacitors at the desired locations to achieve the power factor correction. Shunt capacitors bank utilization in the power factor correction will produce economic saving in capital expenditures through the reduction of power losses through the distribution network which is the main goal of this study. In this study, the professional power system software (EDSA) has been used in developing the network model for the first time in Iraq. The power flow solution has been used in the determination of the energy after adding the shunt capacitors (i.e. after power factor correction). The on-site power factor enhancements and energy measurements have been conducted and verified by the network model that was developed by the professional power system software (EDSA), while Newton-Raphson method has been used to obtain the Power flow solution. Many goals have been achieved in this study, where in spite of the annual reduction in losses or energy saving of 120.96 MWhr (435456 MJ of energy for every one year), the power factor is enhanced to an excellent value (nearly 95 %), where reaching this value for such industrial loads give a remarkable excellent condition.

One advantage of using prestressed concrete structural elements is the control of deflection under normal service load levels. Prestressing permits the use of smaller cross-sections by keeping the section uncracked through design load levels. Also, an uncracked section is particularly desirable where exposure to a corrosive environment is a factor of concern. In the present study, experimental test results are presented for three non-prismatic prestressed concrete beams. The chosen beam shape was the double tee beam, for its wide applicability and in situ performance. The chosen beams had different span length, geometric ratio, amount of prestressing area, loading arrangement and procedure for applying the load. All the tested beams have been cast in the same circumstance in which they were designed to function. The first beam was cast during the time of the present research, and the others were being on storage. The last two beams have been chosen from groups of storage beams, to satisfy the objective of the research. Those beams were fabricated at Al-Rasheid State Contracting Company and were tested in its labs.

This paper is a study of the effect of the dimensional design factors of the discharge tube inside an Electrothermal Accelerator on the axial plasma produced inside the tube. A theoretical approach has been investigated on the base of our previous experimental researches and on the base of universal researches in this field. A low-pressure coaxial discharge is investigated theoretically on the base of one- dimensional axial fluid model. This type of surface-wave-plasma source is relatively new in comparison to the classical cylindrical plasma column sustained by an electromagnetic surface wave. In the coaxial structure the dielectric tube is filled with air at normal pressure and a metal rod is arranged at its axis. The plasma is produced outside the dielectric tube in a low-pressure chamber by an electromagnetic wave traveling along the plasma- dielectric interface. The plasma is both radially and axially inhomogeneous. In this paper we have investigated theoretically the role of metal rod and dielectric tube radii on the wave and plasma characteristics on the base of one- dimensional axial fluid model

This research deals with the nonlinear finite element analysis of non-prismatic prestressed concrete double tee beams under flexure. The numerical analyses have been carried out on beams chosen from the available experimental studies. Two different setups were considered. Beams B2 and B3 were experimentally tested by Mohammed 2003 and meant to represent the case of a non-prismatic prestressed concrete double tee beam. Beam B3, in particular, represents a beam with a short span. Beam B2, on the other hand is a sample for a relatively long span beam. These two beams were tested up to failure. The finite element results are compared with the results of the available experimental tests. Parametric studies have been carried out throughout this study to investigate the effect of some important material and solution parameters on the numerical results. Effects of concrete compressive strength, amount of prestressing steel reinforcement, and initial prestressing forces are studied. A mathematical model suitable for the nonlinear analysis of prestressed concrete beams under monotonically increasing load is used. The validity, accuracy, and efficiency of the computational model are examined by comparing the finite element results with the experimental results.

In the present study, compressive strength, rate of free drying shrinkage of plane concrete and load-deflection behavior of reinforced concrete beam specimens under the effect of fire flame exposure are presented. Plain concrete (150mm) cube specimens and (100*100*500mm) prisms were subjected to fire flame temperatures ranging between (25-550 ºC) at different ages of 30 and 60 days. Two temperature levels of 400 ºC and 550 ºC were chosen with two different exposure durations of 0.5 and 1.0 hour. Cube compressive strength and rate of drying shrinkage were explored after fire flame exposure and compared with the control (unburned) specimens. Ten rectangular reinforced concrete beam specimens (100*150*1000mm) were cast and subjected to fire flame at temperature levels of 400 ºC and 550 ºC, with two periods of exposure 0.5 and 1.0 hour. These beam specimens were tested in flexure until failure after exposure to fire flame and the load – deflection relationship was recorded and compared with that of the control (unburned) beam specimens. Based on the results of this research, the compressive strength of concrete was affected adversely by fire flame and the degree of damage increases when the fire temperature and/or period of exposure were raised. For the fire temperatures and periods of exposure investigated, the residual compressive strength ranged between (70-78%) at 400 ºC and (59-65%) at 550 ºC burning temperature. It was found that the exposure to fire flames increases the rate and intensity of drying shrinkage of free concrete prisms. This increase was found to reach 50% if temperature of fire approaches 550 ºC. It was noticed that the load-deflection relationship of reinforced concrete beams exposed to fire flame is more leveled representing softer load-deflection behavior than that of the control beams. Also, it was found that both the ultimate resisted load and moment carrying capacity decrease remarkably after fire exposure. This can be attributed to the early cracking and lower modulus of elasticity. Also, it was found that the temperature distribution through the thickness of beam is identical for all the beams which have the same thickness

Densities (ρ) and viscosities (η) of urea in Ammonium phosphate solution at different temperature (298.15, 303.15and308.15) K have been measured. The results were used to determine the apparent molar volumes (∅v) and limiting partial molar volumes (∅v°), slop (Sν), Gibbs energy of activation for viscous flow of solution ∆G∗1, 2 and Jones – Doles B coefficients. The results show that solvated Urea shows different types of solute – solute interactions as a result of its dissociation spatially at low concentrations. The results also show that the solvated urea has the property of breaking structure of liquid ammonium phosphate solution with increasing temperature.

Universal Mobile Telecommunication System (UMTS) is a third generation mobile communication technology based on Wideband Code Division Multiple Access CDMA (WCDMA) and can facilitate the users in much better way as compared to the second generation of mobile communication. UMTS is superior to second generation in terms of bandwidth efficiency, quality of service, speech quality, speed and capacity. This paper focused on soft and hard handover techniques in UMTS networks and conducted a performance comparison between soft and hard handovers. The project divided into two scenarios: soft handover and hard handover. Soft handover produces better results in terms of uplink transmission power and enables the mobiles to perform the handover at lower power levels. Soft handover benefit from a concept called "soft handover gain" and the network can lower the quality block error ratio (BLER) below the requested level, then the transmission power can be kept at lower levels during soft handover while still providing the same quality to higher layer. In order to simulate typical UMTS scenarios, OPNETv14 modeler is used and a number of users are generating traffic and are free to move in various cells

The study was conducted in 2008 at the apiary of College of Agriculture , Karbala University to determine outside and inside activities of honey bee, Apis mellifera L. , colonies during the period of sharp decline which usually extends from c. mid – June to c. mid – October and find out the roles of different factors standing behind this decline , especially the bee- eaters , Merops spp. All outside and inside activities of honey bee colonies showed steady sharp decline . The flight activity was either at very low level sometimes or the whole colonies were confined to their hives at many other times. While mean area of sealed brood was somewhat small on 7 July (701. 9 cm2 per colony), it decreased steadily after that to be in the range of 25.8 -152.6 . Mean size of adult bee population decreased from 7.75 and 8.14 sides of combs covered completely with adult bees per colony on 7 and 21 July , respectively to reach its lowest level , 0.59, on 26 October . There was a clear relationship between the presence of bee eaters and stopping of bee flight . The birds were found at the apiary at fluctuated levels . However , their most intensive presence was during the period extending from 1 August to 10 October ,especially at both early and late daytime hours . Many aspects of bee – eater and honey bee behaviors at the apiary were studied in details . In addition to the bee – eaters , there were also other factors participating in this decline including severe rise of ambient temperatures and shortage of nectar and pollen sources . Vespa orientalis L. , had no role at all in present study because it was found in very scarce numbers at the apiary

Flood routing divided into two kinds, hydraulic & Hydrology. Each one of them has properties & features. One of the most important method of routing is the Linear and Non-Linear Muskingham flood routing method. Baiji station has been selected as a case study because outflow & inflow discharges data for a constant period are available. Linear and Non-Linear Muskingham Method is applied using modern computer language ( Mat Lab – Version 6.5 – Release 13). It working with Windows environmental. For each method, we do two programs: the first is to calculate the variables (X,K,m) and the second is to calculate outflow from the Baiji station. Results of the first program for Non-Linear is analyzed in statistical program (SPSS) to calculate linear correlation factor. Also a new method are created (Mixing method) between Linear & Non-Linear, then separate it in another program & use statistical program for it. With insert all necessary statistical graphs and discharges comparisons graphs. Results of Linear Muskingham method is better than Non-Linear & more adequate and close to real data, also when it is used in the third method, it was the best. Results for Non-Linear has been canceled when it use in third method.

Background: This study aimed to assess the potential clinical utility of serum level of serum soluble interleukin-2 receptor (sIL-2R) as a diagnostic tool in rheumatoid arthritis disease (RA). This study investigate the association between serum sIL-2R levels with other parameters used for estimation of RA such as rheumatoid factor (RF), erythrocytes sedimentation rate (ESR), C-reactive protein (CRP), and uric acid. Methods: Serum sIL-2R levels, measured by ELISA, were evaluated in 25 RA patients who have positive RF. SIL-2R values were compared with those of 25 normal controls and the correlation with the other parameters was analyzed. Results: Compared with the healthy control group, RA patients tended to have significantly higher serum sIL-2R and ESR concentrations (P<0.001). While no significant difference between both groups in serum uric acid. Positive serum CRP (CRP level>6mg/dl) were found in 58% of patients. The sIL-2R level was positively correlated with RF and ESR, while a slight positive correlation with uric acid. Serum sIL-2R showed a highly sensitivity and specificity for the patients with positive RF. Conclusions: sIL-2R levels may be useful, sensitive, and specific marker for diagnostic of RA

The a-Ge1-xSbx thin films of (250±20) nm thickness were fabricated according to the weight percentages (x = 0.5, 1, 1.5, 2)%wt, by using the thermal evaporation technique under vacuum (10-6mbar) and (2.7±0.05)Ao/s. The specimens have been exposed to(500rad) -ray. The D.C. electrical measurement were carried out in a range of 0 -3Vol. The effect of -radiation on Hall parameters and optical energy gap were investigated for determining the no. of carriers and controlling on optical energy gap of semiconductors. The examination x-ray diffraction showed that all the films have amorphous nature. There are two activation energies for all films of n-type at (493-305)K that the carriers increase to (41.67 x 1019 cm-3)by increasing the percent to x=2,and they showed a decrease after exposed to radiation to(29.76 x 1019 cm-3) at the same value of x. But the mobility decrease to (0.140 x 10-3 cm2/V.s)by increasing of x to 2 percentage and they are increasing after exposure to  - rays with (0.170 x 10-3 cm2/V.s). The optical energy gap is (0.840eV) for a-Ge(unexposed to -rays), but becomes (0.872eV) after exposure , but it is increasing from (0.786eV) to (0.815eV)after exposed to radiation at x=2. This indicates an absorption edge shift towards high energies due to the effect of radiation.

The wheat bran was added to wheat flour grade zero at 5,10 and 15%, designated hereafter by A,B and C respectively. The grade zero flour was represented by R as a control. Protein percent, moisture content, ash, fibers and gluten were determined. Biscuit was prepared according to Brennan and Samyue method. The diameter and thickness of the sliced product were measured. Qualitative elements were evaluated by 10 referees. Results revealed an increase in the protein per cent, ash, and fiber with increasing the bran per cent in the flour. On the other hand, the moisture content and the gluten percentages were decreased as well as the diameter and the thickness of the sliced biscuit as the bran per cent increased. The results appeared differences in the color, mouth feel, flavor and shape of biscuit between treated and untreated wheat flour. Wheat flour enriched with 15% bran was more acceptable by the referees according to the above mentioned characteristics but less acceptable in the term of the shape as compared with B, A and R, although the differences were not significant. It could be concluded that, it is possible that, addition of 15% bran to the wheat flour zero grade would be possible to produce biscuit with acceptable quality.

الخلاصة

The self-cured acrylic resin is inferior to heat cured acrylic resin from stand point of strength and degree of polymerization. Many attempts have been made to improve these properties. Because heat affects maturity of the chemical reaction of acrylic resin therefore its maintenance during polymerization will affect the mechanical properties of cured resin. This study was carried out to evaluate the effect of different curing time and heat application during polymerization of the self-cured acrylic resin on transverse strength compared with that polymerized in air at 23C ± 5C. Nineteen (90) Self-cured acrylic resin specimens were prepared and divided as follow:- (10) specimens polymerized in air at 23C  5C under press (bench curing) as a control group. (40) specimens polymerized in water at 20C, 40C, 60C, and 80C, under (30 psi) pressure for 15 minutes . (40) specimens polymerized in water at 20C, 40C, 60C, and 80C, under (30 psi) pressure for 30 minutes. All specimens were tested for transverse strength. Results showed that self-cured acrylic resin specimens polymerized in 15 minutes has a significant lower transverse strength than polymerized in 30 minutes. The transverse strength of the test specimens polymerized in water at 20C lower than control group, while all degree of polymerization improved transverse strength, however, in 80C highest transverse strength compared with the other temperatures control group. It can be concluded that increasing curing time and water temperature during polymerization will improve transverse strength of self-cured acrylic resin.

This paper presents a new approach of designing the Power Systems Stabilizer (PSS) that is based on fuzzy neural system. Adaptive Network based Fuzzy Inference System (ANFIS) is utilized in constructing the Fuzzy Neural Power Systems Stabilizer (FNPSS). The employment of ANFIS enables the system avoiding defects caused when using fuzzy logic and neural networks individually in designing an efficient PSS. Single Machine Infinite Bus (SMIB) power system has been taken as a case study to evaluate the suggested strategy performance. Simulation results have been conducted to confirm the approach validity.

الخلاصة

Background: Polycystic ovary syndrome (PCOS) is associated with a higher frequency of cardiovascular risk factor. Lipid profiles are potent markers for cardiovascular risk. Aim of the study: To identify changes in lipid metabolism in women with PCOS and the relative impact of obesity and hyperandrogenism on lipid parameters. Subject and methods: The study was conducted in the period from August 2006 till March 2007 on eighty women, who had been diagnosed as PCOS; they were recruited from IVF Institute of Embryo Research &Infertility Treatment in Baghdad. Twenty apparently healthy fertile women were served as control. Endocrine evaluation and Lipid assays were performed in both cases and controls. Results: There were significant elevations in LH, LH to FSH ratio, Testosterone and Free testosterone levels in women with PCOS when compared with the normal control group. For lipid profile there was a significant elevation in levels of TG, Cholesterol, and LDL in combination with low level of HDL and with an increase in atherogenic index in women with PCOS when compared with normal control group. Conclusion: Amore atherogenic lipid profile, in particular related to HDL metabolism, was found in women with PCOS, both obesity and hyperandrogenism contribute to these changes, and there was evidence for an additional influence of PCOS on lipid metabolism.

In this research new1,3-oxazepine derivatives[6-11] were prepared starting from new Schiff bases [4] and [5]. 5,5'-{[3-(Methoxycarbonyl)-4-oxocyclohexa-2,5-dienylidene]methylene}bis(2-methoxybenzoate) [2] was prepared by reaction of 5,5'-[(3-carboxy-4-oxocyclohexa-2,5-dienylidene)methylene]bis(2-hydroxybenzoic acid) [1] with dimethyl sulphate in presence of anhydrous sodium carbonate in dry acetone. The trihydrazide derivative [3] was obtained from treatment of triester derivative [2] with hydrazine monohydrate in absolute ethanol. Reaction of the trihydrazide derivative [3] with each Furfural and Salicyladehyde, respectively, in presence of glacial acetic acid as catalyst in absolute ethanol resulted the formation of new triimine derivatives [4] and [5], respectively. Treatment of the resulting imines [4] and [5] with each maleic anhydride, phthalic anhydride and 3-nitrophthalic anhydride, respectively, under cycloaddition reactions conditions produced new tri(1,3-oxazepine) derivatives [6-8] and [9-11] respectively. These new imines and 1,3-oxazepine derivatives may be used as antibiotics. The structures of all prepared compounds were confirmed by C. H. N. elementary analysis and FT-IR spectra.

The edge detection process continued by the edge linking which is presented in this paper can be clear by the following: 1) it appears from the results of the edge linking that the part with bright colour is indicative of the big change in the intensity value of the original image, and 2) the edge detection in the geometric shapes or Morphological shapes are more significant or more contrast rather than ordinary image. The edge linking, the gradient components Gx and Gy of the image are present here to detect an edge linking of geometric figure (morphology shape) and digital image. There are three kinds of discontinuity in digital image; they are point, line, and edge. In practice, the most common method to find the discontinuity of an image is to use the mask that is operated in all of the pixels in the image, we use of the masks of the size of (3 * 3). To implement the contrast stretching process in a computer, we present an algorithm to Sobel method to write a program able to 1) open the file containing digital images, 2) display the digital image in the screen, 3) process the edge linking, and 4) display the digital image resulting from the process, and we used image file in BMP format and of the size of (256 * 256) pixel with 256 grey level.

A series of new cyclic imides containing phenazone heterocycle were prepared via following three different methods. The first one involved direct reaction of different cyclic anhydrides with 4-amino phenazone producing the corresponding amic acids which subsequently introduced in dehydration reaction to afford the desirable imides while the second method involved treatment of 4-amino phenazone with chloro acetyl chloride affording 4-(2-chloro acetamido) phenazone which introduced in reaction with potassium salts of both phthalimide and succinimide producing N-(2-acetamido phenazone -4-yl)phthalimide and succinimde respectively . The third method involved reaction of 4-(2-chloro acetamido) phenazone with N- ( hydroxy phenyl) phthalimides producing three new N-(oxy acetamido phenazone-4-yl) phenyl phthalimides. Antibacterial activity of the prepared new imides against two types of bacteria were evaluated and the results showed that the new imides exhibit good to moderate antibacterial activity. Antifungal activity of the new imides were also tested against candida albicans fungi and most imides showed slight activity against this fungi.
