We present in this paper the development and implementation of a new
steganographic method, the information will be hidden in the selected parts of the
table with floating-point numbers used as stego cover. The method is implemented
by transform each character in the text into numbers, then stores it as part of the
floating-point number. The main goal of steganography was fulfilled since the
resulted table did not drown any suspicion, the same table can be used by
experimental person for the different calculation.

The most important topics that constitute the aesthetic and substantive aspect of the theatrical performance represented by the spatial environment of the presentation and the proposed virtual place that contains the technical and artistic elements of the presentation and highlights the strength of influence on it. In light of the above, the researchers divided the topic into four chapters.

The first chapter contained (the methodological framework), which included the research problem with regard to the directing treatments between the directors in establishing or creating theatrical venue, the importance of the research and the aim of the research, and the limits of the research to conclude the chapter by defining the terms.

The twentieth century witnessed developments, transformations and artistic revolutions, including what was witnessed in Arab art, especially contemporary Iraqi plastic art, and as a result, research and studies have increased that dealt with its topics in different ways, which has become a presence that gave it its own language and unique discourse, especially the body, thus opening the way for its employment in composition, to become a form. It denotes interpretable meanings through its various formal representations, which are artistic, cultural and cognitive products. The modernity of the Iraqi formation in the body has passed through different roles, so it started to deal with the body as a representation that reflects the real envir

The Qazaniyah study included the analysis of 18 wells and 2 springs for the dry period in October 2018 and the wet period in April 2019, including the analysis of physical and chemical properties and the study of heavy elements (Fe, Zn, Cd, Pb, Ni and Cu).The results showed that the water wells and springs for the two periods are highly mineralized and characterized by low alkalinity and very high hardness. Water was fresh in some wells and salty in the others, whereas it was fresh in the springs. Most  of the wells had sodium chloride type, except the wells 12, 7, 6, and 5 which were of Calcium chloride type. The springs for both seasons had calcium chloride type. Based on the World Health Organization criteria ,  all the well

In this paper, we investigate some methods to solve one of the multi-criteria machine scheduling problems. The discussed problem is the total completion time and the total earliness jobs  To solve this problem, some heuristic methods are proposed which provided good results. The Branch and Bound (BAB) method is applied with new suggested upper and lower bounds to solve the discussed problem, which produced exact results for  in a reasonable time.

The current study included the preparation of the aqueous extract of Raphanus sativus (Brassicaceae), commonly known as radish which is widely available throughout the world and has been used in folk medicine as a natural drug against many toxicants. The study was designed to evaluate the in vivo cytogenetic activity of the crude aqueous extract of R. sativus on mitosis on Allium cepa root tips as a plant test system. Root tips of A. cepa were tested for four hours with four concentrations of the crude aqueous extract (0.00, 5, 10, 20, 40 mg/ml). The study included a number of cytogenetic analyses such as mitotic index, phase index, and chromosomal aberration. The data s

This study was carried out to at the poultry farm of the college of
veterinary medicine / Baghdad University during 12/5/2004 – 6/7/2004 to
study the effect of substitution of smut wheat instead of intact wheat in
poultry ration at the following levels (0%, 25% , 50% and 100%)
representing the following groups (T0, T1, T2 and T3), respectively. Physical
treatment was obtained for smut wheat by polishing the seed by sand to
remove the superficial fungal growth. Each group was sub divided into two
sub groups, one was physically treated with sand and the other was not
treated to study the hematology traits at 28 and 56 days of the experiment.

In this paper, we establish the conditions of the occurrence of the local bifurcations, such as saddle node, transcritical and pitchfork, of all equilibrium points of an eco-epidemiological model consisting of a prey-predator model with SI (susceptible-infected) epidemic diseases in prey population only and a refuge-stage structure in the predators. It is observed that there is a transcritical bifurcation near the axial and free predator equilibrium points, near disease-free equilibrium point is a saddle-node bifurcation and near positive (coexistence) equilibrium point is a saddle-node bifurcation, a transcritical bifurcation and a pitchfork bifurcation. Further investigations for Hopf bifurcation near coexistence equilibrium point are

In this paper, the asymptotic behavior of all solutions of impulsive neutral differential equations with positive and negative coefficients and with impulsive integral term was investigated. Some sufficient conditions were obtained to ensure that all nonoscillatory solutions converge to zero. Illustrative examples were given for the main results.

Eight food materials were used. They affected differently the biology of this
beetle. Females laid highest number of eggs when fed on raw wool (٤٥ eggs), then
on goats hair (٤٠.٤ eggs) lowest number of eggs (١٧.٢) when fed on natural silk, and
(١٨ eggs) on sheep hide.
Larval duration was shortest on raw wool (٧٨.٤ days), then goats hair (٨٤.٨ days)
and camels hair (٩١.٨ days). It was largest on human hair (١٧٦ days) and natural silk
(١٧٣ days). Larval mortality was lowest on goat’s hair (١%) then on raw wool (٤%)
and highest on natural silk (١٦%) and human hair (١٢%). Other material lies between them. These materials affected variably pupal duration, adult emergence.

Although cinema is moving towards art, it has dealt with the character since the beginning of the discovery of cinematic art in films such as (Doctor Caligari's cabin) and most German expressive films in the third decade of the twentieth century, but the interest of cinema is growing in the estranged human personality, meaning that this character It lives by its alienation from the environment and society that surrounds it, because our present days have witnessed on the material and moral level more social breakdowns such as wars and disasters, and the sharp contradiction in the social and economic level of people themselves or between different societies, or between the individual and his community, and new social relations have increas

The 2001 outburst of WZ Sagittae has shown the most compelling evidence yet for an enhancement of the mass transfer rate from the donor star during a dwarf nova outburst in the form of hot-spot brightening. It has been shown that even in this extreme case, the brightening can be attributed to tidal heating near the interaction point of an accretion stream with the expanding edge of an eccentric accretion disc, with no need at all for an increase in the mass transfer rate. Furthermore, it has been confirmed previous suggestions that an increase in mass transfer rate through the stream damps any eccentricity in an accretion disc and suppresses the appearance of super-humps, in contradiction to observations. Tidal heating is expected to be

مما لا شك فيه أن ظاهرة عدم المساواة في العمل أو التعليم وفي كافة مجالات الحياة الأخرى بين الذكور والاناث من الظواهر التي تستحق الدراسة والتحليل لاسيما وانها من الظواهر الخطيرة وتتجسد خطورتها على جميع الاتجاهات والمستويات فلها آثار سلبية على المرأة باعتبارها الجزء أو النصف الثاني من المجتمع وتعتبر اللامساواة من المعيقات الأساسية للتنمية. ولهذا نالت هذه الظاهرة اهتمام العالم أجمع من دارسين وباحثين ومختصين

Millisecond pulsars (MSPs) type have properties differs from normal pulsars type. In this research the characteristic age are concentrated depends on the periods (P), and period derivative (P`) for a sample stars which adopted. Also the value of characteristic age for these stars is determined by depending on the (Ostriker and Gunn) model. The relation between luminosity and the characteristic age for a sample of MSPs stars are illustrated depending on pulse periods for these stars. The results indicate that the spin down torque must decay with the characteristic age for a sample stars which adopted. Also the results for these stars at distance 1.5 kpc from the galactic disk illustrated that the decay must due to the main energy loss mec

الوجود الحقيقي عند سارتر هو الوجود الإنساني .. أما الوجود العام فهو لا قيمة له ، لأنه يخلو من الشعور كالجماد والحيوان .... وقد وصف الوجود بأنه ناقص ، لذلك كان عالم الوجود الإنساني في صراع دائم للوصول إلى ما يريده . بل الإنسان لا يمتلك طبيعة جوهرية ثابتة يتشكل بها وجوده لذلك يكتسب صفاته من خلال أفعاله التي اختارها . وأهم من كل شيء فإن الوجود هو الحرية نفسها .

لقد كثر الحديث في الفترة الاخيرة عن الجفاف وشحة المياه في العراق ، وبعد ان بان هذا الامر بشكل واضح لا يقبل التأويل أصبح موضوع المياه ونقصها وتردي نوعيتها تحديا كبيرا يتطلب من دول المنطقة وضع الاستراتيجيات ضد الأخطار التي تواجهها ، مما قاد هذا الأمر العراق إلى استعمال جزءٍ كبير من مخزونه الاستراتيجي في السدود والخزانات إذ أصبح لزاما التنسيق المسبق بين الدول المشتركة في مياه نهري دجلة والفرات وهي سوريا وتركي

The arrangement of the letters and words in the Holy Qur'an is based on a form of literary and spiritual subtlety consistent with the human soul. Despite the implications and audio phenomena, the Qur'anic tone is achieved by the harmony and proportionality of a set of components of the letters and words that appear soothing for ear, surprises the souls and amuses listeners by the grandeur of its meaning. The present study has tried to investigate the repetitive audio phenomena in Al-Qalam (The Pen) Sura through a descriptive and analytical-statistical method; the findings indicate managed to prove such a phenomenon, especially in some specific letters, including  A, L, N, M, W, Ya'a, Ba'a, Ra'a and Kaff out of 28 Arabic letters.
