Steganography in MS Excel Document Using Unicode System Characteristics

Aliea Salman Saber

Journal of Basrah Researches (Sciences), Volume 39, Issue 1, Pages 10-19

The massive explosion in computer technology and communication has encouraged the development of steganography and watermarking, breathed the spirit of steganography, and made it the top security technique to protect and preserve the rights and privacy. So, steganography is one of the important types of information hiding techniques that has evolved a lot in the recent years.
Most text steganographic methods take the formatted text documents, such as, MS Word, PDF, PPT …etc., as a cover to hide secret information. This study concerns the steganography in MS Excel document and proposes a new steganographic method for hiding information efficiently by Unicode system characteristics technique. In the Unicode standard, there are two different codes for seven numbers (0, 1, 2, 3, 7, 8, 9) in Arabic and Persian Language. The seven numbers of (0, 1, 2, 3, 7, 8, 9) have the same shape but different codes in Unicode table. As a result, we can hide information in MS Excel Document, by using one of these two codes.
This proposed method has a high capacity. It can hide one bit in each number in the cover_file, and it is not make any apparent changes in the original text. So it satisfies perceptual transparency. In our method, we have increase the level of security by encrypting the secret message before embedding it by using Advanced Encryption Standard (AES-128) algorithm.

In this paper, a new technique is applied to develop the treatment of initial boundary value problems for one dimensional heat-like and wave-like partial differential equations [3] (ordinary or fractional) by mixed initial and boundary conditions together to obtain a new initial solution at every iteration using homotopy perturbation method (HPM). The structure of a new successive initial solutions can give a more accurate solution in a first step.

A field experiment was conducted to evaluate the effect of conventional tillage (CT), Reduced tillage (RT) and No-Tillage (NT) systems using three seeding rates (100, 120, and 140 kg ha-1) of two barley species Hordeum vulgare L. cultivars namely Arivat and IPA-99. The aim of the experiment was to develop management strategy for selecting tillage system, seeding rate, and cultivar to increase yield of barley under semi-arid conditions. The experiment was laid out in randomized complete block design with split-split plots arrangement having tillage systems as main plot, cultivars as sub plot and seed rates as sub-sub plot. CT and RT was more effective in enhancing tiller number, plant height, spike number, seed yield and biological yield as compared with NT. Tiller number, plant height, spike number, seed yield and biological yield for the highest seeding rate was 24.253, 5.285, 44.142, 31.108, and 9.128% respectively greater than for the lowest. IPA-99 cultivar had more tillers per unit area, spike number, seed yield, biological yield, harvest index and higher plants than Arivat cultivar. However, Arivat cultivar had higher kernel per spike and thousand kernel weight. Negative correlation coefficients were found between spikes number and kernels per spike of -0.691 and spikes number and kernels weight of -0.943. Applying seed rate of 140 kg ha-1 with IPA-99 cultivar under CT seems to the promising combination for semiarid barley.

Food allergies are important health problems. Since there are no previous studies to assess food allergies to beef in Iraq. So the aim of this study reveals food allergies by using immunological and genetic testing . Two hundred and sixty four sera from suspected meat allergic subjects were tested by in direct ELISA for specific IgE antibodies to beef .Polymerase chain reaction technique was performed to detect genetic relationship between food allergy and human leukocyte antigen classII allele(HLA -DQB1*0305). Depending on the ELISA seropositivity results, 13.3% of allergic patients were seropositve against beef allergens raw and cooked and the higher rate of seropositivity was observed in males (14.6%) and in 2nd age group patients (17.9 % ) in concern to sex and age effect on the seropositivity.There were non significant (p>0.05) variable values of optical density mean and standard deviation. The loss of beef allergy was not observed in all allergic patients and all of them showed the same positive raw and cooked beef specific IgE response .The results of PCR amplification showed successful binding between the specific primers of HLA- DQB1*0305 and the extracted DNA appeared as single band of expected size, 195bp . The positive specific IgE response to beef allergens was significantly associated with HLA DQB1*0305 .

The aim of this study was to optimize the cultural conditions for optimal fungal growth and metabolic bioactivity of Rhizoctonia solani isolated from potato tubers in Basra, Iraq. Different culture media, temperatures, pH and carbon and nitrogen sources were used to elucidate their effects on the fungal growth response and bioactivity of the fungal metabolite against two bacteria strains E. coli and S. aureus. R. solani grew better on Trypto Soyo broth medium at pH 6 and temperature 30 C. Starch (C- source) and NaNO3 (N-source) were most suitable for the fungus growth. Highest dry weight of fungal crude extract was obtained by using TS broth medium at pH 6 and incubation temperature 30 C. A disc diffusion technique was applied to examine the bioactivity of fungal crude extract against two strains of bacteria E. coli and S. aureus. The fungus exhibited higher antibacterial metabolic bioactivity (30 mm and 34 mm inhibition zones diam) against E. coli and S. aureus, respectively, by using TS broth medium amended with starch and (NH4)2SO3 at pH 6 and 25 C temperature.

concentration of Boron is assess in water samples which are taken from different Regions in Basrah City. A technical method has used in two sets of experimental works in the measurements of Boron concentrations in water. The first measurement by using Curcumin method and the second is the passive method by using the solid state nuclear track detectors,CR39. Tap water in the governorate, has a very low Boron concentration 0.539 ppm at Al-Bedeah river. Shatt Al-Arab Al-Jzeera AlOula did show a Boron level as high as 7.405 ppm at east governorate, waters have Boron level ranging between 7.785mg/l and 0.638 mg/l in curcumin method. A conclusion has been made, that Basrah governorate tap water is safe as far as Boron concentration is concerned, while the rivers waters should be avoided. The high concentration tells us that pollutant in this part of the city is larger than the other parts. Samples of water were collected during February 2012, from all the locations in Basrah City.

Journal of Basrah Researches (Sciences), Volume 39, Issue 1, Pages 143-147

This paper describes the influences of the centres in (1+1) dimensional external trapping potential which are usually used in the experiment that leads to produce Bose-Einstein condensation BEC in ultra cold gases. Two mixed types of trapping potential are used in this analysis, the first one is a harmonic oscillator potential HOP which is applied along the Y-axis, and the second is a double well potential DWP which is applied along the X-axis. The results show that the value of a, in DWP formula have a major effects on the potential in terms of shape and value.
