The purpose of this paper is to construct the concept of fuzzy proper mapping in fuzzy topological
spaces . We give some characterization of fuzzy compact mapping and fuzzy coercive mapping . We
study the relation among the concepts of fuzzy proper mapping , fuzzy compact mapping and fuzzy
coercive mapping and we obtained several properties.

This work presents a new approach to accommodate routing demands in a highly dynamic
network where segment status is rapidly changing to find the best path ,the router does not need to look
at the network as a whole, as it is the case in routing algorithms designed so far . The proposed system
consists of several agents (multi-agent) shared by some types of information for the purpose of
clarifying the case of the network in general in the way to suggest the best path, which is used by the
message from the source to the destination. Each agent activated at each router called Agent Suprouter
to acquire local data of the current router ,this data gathered from the neighboring agents in
order to direct path of moving packet from source to destination . In the proposed system , an
intelligent notification message exchanged by Agents Sup-routers enable the system to evaluate the
current status of the network instantly. This status has been acquired by the proposed distributed
Intelligent Agents as an initiation for finding the best path. The proposed system has been implemented
using java language and JADE platform

Stream cipher is one of the efficient cryptographic primitives to provide confidentiality of
electronically transmitted data. Where it is widely used in practice (e.g., in mobile phones, internet ).
Researches are interested with different types of attacking on stream ciphers. This paper provide
classification for types of attacks on stream cipher and concentrate on the algebraic attack, since it
represent the most important among them. Also the paper presents proposed developed clock control
keystream generator based on combiner, that has an increase in the complexity of the structure. The
Algebraic cryptanalysis was applied for comparing the resistant of proposed generator with LILI
keystream generator.

Electronic mail messages have become increasingly important and widespread method of communication
because of its time speed ,where the amount of email messages received per day can range from tens for a
regular user to thousands for companies. Nowadays; The spam mail messages are mainly a illegal form
where thousands of users are easily reachable. This type of emails has become a serious problem. In this
paper was proposed a method of classifying emails using the concept of association rules

The traffic in urban roads regularized by traffic lights, that distribute fixed time for intersection
sides, which may be crossing time of vehicles for some sides and long waiting time for others in the
intersection. In this work we proposed Agent subsystem which is local responsible for controlling the
time periods to be distributed over time to each intersection according to the vehicles queue length and
give the priority for the side that have the longer queue length of vehicles. The perception for this agent
are sensors that evaluate the queue length at each intersection side of the traffic light location, and the
effecter will be the distributed time for the intersection sides

The effectiveness of crude extracts of Camellia sinensis and Cinnamomum zeylanicum in the growth of Trichophyton mentagrophytes that causes some types of Tinea were investigated in addition to determining the value of the minimum inhibitor concentration (MIC) of plant extracts against this fungus . The results of the experiment showed that the inhibitory effect of cold water extract of Cinnamomum zeylanicum on growth of Trichophyton mentogrophytes was significantly (0.05) higher than that of Camellia sinensis extracts after 5 and 7 days at 50, 75, 100 mg / ml concentration. On the other hand, the hot water extract of Camellia sinensis was significantly higher inhibitory effect than that of Cinnamomum zeylanicum at 50, 75, 100 mg / ml concentration for both periods. Similarly the alcoholic extracts of Camellia sinensis was more effective in inhibiting the growth of the T. mentogrophytes than that of Cinnamomum zeylanicum but at all concentration used (25, 50, 75, 100 mg/ml) for the duration of the experiment, in spite of that both extracts were less inhibitory effect than that of antibiotic Fluconazole.The results showed that the value of the minimum inhibitory concentration of cold water and hot water extracts was 25 mg / ml, while in alcoholic extract was 12.5 mg / ml for Camellia sinensis extracts and 25 mg/ ml for Cinnamomum zeylanicum extract.

A total of forty two Proteus isolates were isolated and identification. These were included 38 isolates (90.48%) of P. mirabilis and 4 isolates (9.52%) of P. vulgaris. The antibiotics sensitivity of the isolates were tested against 18 of antibiotics. The biofilm isolates showed multidrug resistance to antibiotics in comparison with urine isolates. The plasmid profiles of four biofilm isolates and three urine isolates of P. mirabilis, and two isolates of P. vulgaris one from biofilm isolates and the other from urine isolates were studied, it was found that all of the isolates contain small single plasmid with molecular size equal to molecular size of pBR322. The transformation experiments showed that the Proteus plasmids have ability to expression in Escherichia coli MM294, and it had a wide host rang. The genes responsible for resistance of ampicillin, tetracycline, chloromphenicol and co-trimixazole were located on these plasmids

The toxin vaginolysin of bacteria G. vaginalis which isolated from clinical specimen of women infected with bacterial vaginosis in special culture media for this purpose then toxin was partially purified by sephadex G 200 , then toxin hemolytic activity for crude was found 160 unit/ml , after precipitation with ammonium sulfate 320 unit/mg and after gel filtration was 160 unit/ml specific activity also was found for crude 10.6 unit/mg for precipitation with ammonium sulfate 29.09 unit/mg and for gel filtration was 94.09 unit/mg and after that protein concentrations were found .

Objective: to determine the level of serum testosterone in preeclamptic(PET) groups and normotensive pregnants women in second and third trimister.
Methods: Fifty five pregnant women with preeclampsia (PET) (twenty five of them in the second trimester of pregnancy while the rest of them were in the third trimester of pregnancy and the same number for healthy pregnant women.
Results: serum testosterone was significantly higher in preeclamptic groups compared with normal pregnants women groups(p<0.001).Also serum testosterone was significantly higher in the third trimester compared with second trimester for preeclamptic groups (p<0.001), and also shows nonsignificant decrease in third trimester compared with second trimester for healthy pregnant women(p=0.36).

In the present work attempts were, made to verify the hypothesis that aging may suppress cryoglobulin responses among pulmonary tuberculus patient .
Two main groups of test pulmonary tuberculus patients one with age group of ≥ 60 years (aged) and the other with age group of ≤ 55 years (non aged) patients. These two groups were equaly subdivided into males and females subgroups. Apparently healthy normal subjects were elected as control with same age groups as test patients. The test and control groups were subjected to study of Cryoglobulinemia responses in accordance with Irish guide line for study of Cryoglobulinemia.
The aged patients of ≥ 60 years old showed low Cryocrit percent, low CRP levels and high RF level, C3, C4 and IgA in comparison to non aged ≤ 55 years old patients which showed high Cryocrit percent, high CRP levels and low RF level and IgA levels.
This Cryoglobulinemia associated is secondary to Pulmonary Tuberculosis and of mixed IgG-IgA-IgM types.
Cryocrit percent, RF, C3,C4 and Igs class determination proved to be valid battery of tests for immunodiagnosis of Cryoglobulinemia and for testing the effect of aging.
