This study deals with constructing and implementing new algorithm based on hiding a large amount of data (image, audio, text) file into color GIF image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixels are selected randomly with Path-based animation rather than sequentially using new concept. This concept based on both visual and statistical that defined by main cases with there cases for each byte in one pixel. High security layers have been proposed through multi layers to make it difficult to break through the encryption of the input data using RC6 algorithm. The proposed algorithm can embed efficiently a large amount of data that has been reached to 86% of the image size with high quality of the output.The proposed method depended on two factors: First, the image which is containing the encrypted text, this image is GIF type which is the abbreviation of (Graphics Interchange Format Image), and the Second factor is the text targeted by encryption and entering within the image.

Results of the study were revealed that , the increases of salt concentrations causes a decrease in the percentage of seed germination and an increase on the concentrations of total and reduced sugar , sucrose , proteins and proline on the shoot system , besides a significant differences between the different salinity treatments .

Braille is one of the important means of written informational communication between visually-impaired and sight people, so it gains the research interest. This paper describes a new technique for recognizing Braille cells in Arabic single side Braille document. The mean challenge in (OBR) system -which is resolved here- is how to binaries Braille image So we suggested two algorithms two binaries Braille sheets based on morphological operations. We apply morphological tophat filter on green Braille documents and morphological bothat filter in yellow Braille documents. Optical Arabic Braille Recognition system has two main tasks, first is to recognize printed Braille cells, and second is to convert them to regular text. We introduce in this search, automatic system which converts printed Braille Arabic to binary digital format to perform the first task from recognition system then we convert character result into binary string and used template matching to recognize this character after that the character translate into text based on ASCII code which map for each Arabic letter. The recognition rates for green Braille documents were between (98.04% - 100%) and (97.08% - 99.65%) for yellow Braille documents while execution time was between (8-38 s.) .

Data hiding is the transfer of data or information between two points to prevent any not authorized person to access about them .This paper concerned with hiding the data in the file of the type of MIDI file (Musical Instrument Digital Interface) to prevent hackers from obtaining confidential data .To increasing the the data security , the data encrypted before hide them using RC5 algorithm . In this paper ,we use the last significant bit algorithm to hide the data and we depending on the value of velocity for each tone in order to hide largest possible amount of information , so the listener to a file cannot recognize if the file contains additional or factual information for velocity . from the experiences, we have seen that is we cannot hide the data or information in all the tone values that representing the MIDI file because we can notice the change on the file , but when we use the velocity values to hide, that there is no great difference between the file contain the hidden data and the original file where we made matching using the meldistance function

Methotrexate (MTX) has been supported by the polypeptide (insulin). the degree of MTX incorporation into polypeptide (1:0.5) the molar substitution ratio was applied in the experimental reaction . the spectrophotometers were used for characterization of MTX-polypeptide product. The in vitro coupling of MTX-polypeptide are shown to be an inhibitant of L.donavani growth. The growth rate of parasites decreased in parallel with increasing the concentration of MTX- polypeptide (0.02, 0.04 and 0.06 mg/L) & lowering as compared to the control group. The growth rate is counted during period of as long as 72 hrs. The maximum decline in growth rate was obtained in the third day at concentration of 0.06 mg/L of MTX- polypeptide. There is a significant difference (p<0.05) in replication rates of promastigotes among the different concentrations of MTX- polypeptide (mainly at 0.06 mg/L).

This study included testing the effects of alcoholic extracts treatments for fruits of pepper plant (Capsicum annuum L.) and roots of alfalfa plant ( Medicago satvia L.) and two fungal filtrates of Trichoderma harzianum Rifai and Aspergillus niger Van Tieghem and interference treatments between them in the fungi that associated for seeds of some legumes plants are mung bean, Cowpea and broad bean seeds, and study the effect this treatment in radial growth and dry weight for some fungi isolated from this seeds, and in germination of it's spores, length of germinal tube, and testing the effect of the antifungi in growth of some pathogenic fungi on solid culture medium potato's Dextrose Agar, and also testing the effect of this treatments in germination of seeds on solid culture medium (PDA) and in sterilized and un sterilized soil. The results showed that there is significant difference, the percentage of seeds germination between filtrates and extracts treatments, and the concentration 15 mg/ml from extracts and 15% from filtrates gave high germinations percentage which hasn't significant difference about treatment of fungi disinfectant (Benomyle) at level of possibility 5%, and related to the interference treatments the results showed there are significant differences in the percentage of seeds germination in measuring with controlled treatment and treatment of fungi disinfectant (Benomyle) at level of possibility 5 %.The all single filtrates and extracts treatment and interference treatments were had significant inhibited effect for radial growth and spore germination of tested fungi on solid culture medium (PDA) in measuring with controlled treatment at level of possibility 5 %.These single treatments and interference treatments were reduced from the everage of radial growth of fungi in signifigant in measuring with controlled treatment at the level possibility 5%.These results showed that single filtrates and extracts treatments and interference treatments where increased from percentage of seeds germination in measuring with controlled treatment at level of possibility 5%.

With its new features such as multi-homing, multi-streaming, and enhanced security, the Stream Control Transmission Protocol (SCTP) has become a promising candidate to join UDP and TCP as a general-purpose transport layer protocol. However, the challenge faced by SCTP in the best-effort network, where the network does not provide any Quality of Service (QoS) for the upper layer. The objective of this research are to measure the performance of both TCP and SCTP over a wired network in term of packet loss rate in a network environment that has SCTP with UDP traffic, and then compare SCTP and TCP performance results. All experiments have been done through the network simulation NS2. The result indicates that the SCTP traffic had a highest packet loss rate than TCP traffic under similar conditions.

The Exp-function method is one of the powerful methods that appear in recently years for finding exact solutions of different types of nonlinear differential equations. In this work the Exp-function method has been used to find travelling wave solutions of coupled Burgers equation and Boussinesq regular system. The method allows us to found exact solution of coupled Burgers equation and Boussinesq regular system.

Steganography is the practice of encoding secret information in indiscernible way. Audio Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. It is mainly required for increasing security in transferring and archiving of audio files. Steganography complements rather than replaces encryption by adding another layer of security- it is much more difficult to decrypt a message if it is not known that there is a message. The basic idea of the paper is hide information in cover audio by using linear feedback shift registers LFSR with the Least Significant Bit (LSB) coding to hide data for it and the proposed method hiding data in audio signals using LFSR to select any LSB of audio signals. this proposed method has more security than classical methods because the analysis didn't know any vector used for hide data and proposed method has low noise audio signals than classical method because less number of LSB used for hide data ,the proposed method was applied on two experimental for hiding data and extracting the embedded data in audio signals and applied the noise tests mean squared error (MSE) and Signal-to-noise ratio (SNR) and peak signal-to-noise ratio (PSNR) on it .

In this paper, we present a technique to recognize a query person whose human face image is given w.r.t. a specified database. The main idea of our approach is to use the most important geometric feature positions on the half face image. We construct vector of measures between chosen essential features points of the face such as eyes, nose, chin, mouth, face boundaries and so on, and then reduced to vector of measures. The information taken from frontal view images, yet profile view face images are with small rotation degree to different directions. We used the ANN technique to determine whether or not the query person is recognized. We applied 64 human face images taken from the ORL database and 160 real human face images concerned some Iraqi persons. The recognition results show that the recognition rate is 100% for images taken from both databases.

One way of security is Image Scrambling. Scramble in general mean, scattering all elements in a random ways. Scatter the pixels of any image in the way that which can’t recognize the image, that is called “Image Scramble”. There are many types of image scrambling. The proposed method in this paper deals with a series of shift registers and using XOR gates. The scrambled image having good security by using many tests of the results. The proposed algorithm can applied to the images in a real-time applications, and the implementation is easily done.

In this paper we discussed the existence of ( k, n; f ) – arcs of type ( 1, n ) in the projective plane of order nine; when Im( f ) = { 0, 1,  } and 1<  < n, where , i.e. n = 4 or 10. For this purpose we use the technique in reference [12] and we deduced the example (19, 4; f ) – arc of type (1, 4) when  = 2, and we have an ordinary (13, 4) – arc of type (1, 4) in PG(2, 9), when  = 3. Also we have the examples ( 46, 10; f ) – arc when  = 2 and the monoidal ( 11, 10; f ) – arc when  = 9, which is of type ( 1, 10 ) in PG( 2, 9 ). Also we proved there are no ( k, 10; f ) – arcs of type (1, 10), in PG(2, 9), for other values of  (  ≠ 2 and 9 ) .
