Abstract

DES is a block-cipher employing a 56-bit key that operates on 64-bit blocks. DES has a complex set of rules and transformations that were designed specifically to yield fast hardware implementations and slow software implementations.(4)DES is still strong enough to keep most random hackers and individuals out, but it is easily breakable with special hardware by government and some criminal organizations. The obvious disadvantage of standard is that; since it is accepted on nationwide (or even worldwide) basis, therefore the probability of being someone finds a solution is exceedingly large. In addition to its widely used then the cryptanalyst knows that, by breaking it, he will gain access to many users' messages. Thus, if he finds a method of attack, it will be worth his while to implement it no matter what the cost. Thereby, DES is getting too weak, and should not be used in new applications. This research is focused on DES Key scheme as it is in current use and is not a treatise of the whole field. The major purpose of the research is to fulfill enhancement to DES algorithm by sophisticating its key procedure in order to increase overall computational complicity and to create new individual not to be breakable as easy as with published standard DES, by myriad criminal organizations and any other malicious and to provide the capability of the real example of cryptography to be use today. Absolutely it is impossible to guarantee that this particular instance is not solvable in polynomial time. Consequently, it is reasonable there is always a danger, hopefully very small, that someone may be finding a way to break the system.

هو نظام كتلويِ يَستخدمُ مفتاح (56 بت) يعمل على كُتَلةِ نص (64 بت). ونظام DES عِنْدَهُ مجموعة معقّدة مِنْ القواعدِ والتحويلاتِ اللتان كَانتا مصمّمتين خصيصاً لإنْتاج تطبيقاتِ الأجهزةِ السريعةِ وتطبيقاتِ البرامجِ البطيئةِ (8)DES ما زالَ قوي بما فيه الكفايةُ لإبْقاء أكثر لصوصِ الكومبيوتر والأفرادِ العشوائيينِ خارج امكانية العمل، لَكنَّه قابل للكسرُ بسهولة بالأجهزةِ الخاصّةِ لدى بَعْض المنظماتِ الحكوميةِ ومنظمات الجريمة.إنّ الضررَ الواضحَ لهذا النظام هو؛ حيث ان DES مقبولُ على صعيد عموم البلد (أَو على الصعيد العالمي)، لذا فان إحتمال وجود شخص ممن يمكنه إيَجاد الحَلّ كبيرُ جداً. اضافة إلى أن كثرة استعماله يولد القناعة لدى المحلل بأنه، بكسره، سَيَتمكّنُ من الدخول إلى العديد مِنْ رسائلِ المستعملين. وهكذا، فإذا وَجِدُ طريقة للهجومِ، سَتَكُونُ ذات قيمة عالية عند التَطبيق مهما كانت الكلفة. بذلك، يُصبحُ DES ضعيف جداً، ولا يَجِبُ أَنْ يستعمل في التطبيقاتِ الجديدةِ.هذا البحثِ رَكَّزُ على مجال خوارزمية المفتاح لنظام DES فقط كما هو في الإستعمالِ الحاليِ ولَيس على عموم الخوارزمية. إنّ الغرضَ الرئيسيَ للبحثِ أَنْ يُنجزَ تحسينَ على خوارزميةِ DES مِن خلال إجراء التعقيد على المفتاح المستخدم حاليا ً لكي يَزِيدَ التعقيد الحسابيَ العامَّ ولخَلْق نموذج مفتاح جديدِ لا يَكُونَ قابل للكسر بسهولة كما هو منشور بالنسبة الى DES ، بمنظماتِ الجريمةِ والمتطفلين ولتزويد الامكانية والقابلية على وجود نموذج حقيقي جديد للتشفير يُمكن إستعمالة اليوم.بالتأكيد من المستحيلُ الجزم بضمان أَنَّ هذه الحالةِ لَيستْ قابلة للحلَ في الوقتِ المتعدّد الحدودِ. ولذلك، من المعقولُ القول بان هناك دائماً خطر حتى وان كان صغيراً جداً، بوجود شخص ما قَدْ يتمكن من ايجاد طريقة لكَسْر النظامِ الحالي.

Abstract

Methods; A total of 264 women with preeclampsia have been chosen. They were randomly allocated either to the study group (N=132) or control group (N=132). Patients in either group had mild, severe or chronic hypertension with superimposed preeclkampsia. Patients in the study group were assigned to receive 20 mg furesemide plus potassium orally for 5 days only, while patient in the control group received none. Oral antihypertensive drugs were used only when diastolic blood pressure was eeither above 90 mmHg on 2 occasions, or 110 mmHg single reading. The total days for need of oral antihypertensive drugs as well as the total days spent inpatients were recorded. Patients with severe preeclampsia where categorized as those who have low platelets count as well as high serum liver enzymes in addition to the ordinary signs and symptoms of preeclampsia; hypertension, proteinurea and edema.

الطريقة؛ تم اختيار 264 مريظة مصابات بطليعة ماقبل الاتجاج. تم تقسيمهم بشكل عشوائي الى مجموعتين؛ مجموعة الدراس ( 132) و مجموعةالضابطة ( 132) . بعد الولادة ب 24 ساعة اعطيت للنساء بمجوعة الدراسة عقار لازيكس بجرعة 20 ملغرام يوميا لمدة 5 ايام مع حب بوتاسيوم. بينما لم يعطى أي من الذكور لدى النساء في المجموعة الضابطة. استعملت العقاقير المضادة لارتفاع ضغط الدم حيث كان قياس ضغط الدم الواطي يتجاوز 90 مليميتر زئبقي. تم تقسيم النساء في كلا المجموعتين الى 3 مجاميع فرعي: النساء المصابات بطليعة ماقبل الاتجاج الخفيف و هن المصابت فقط بارتفاع ضغط الدم مع زلال الادرار فقط. اما المجوعة الثانية فهن المصابات بطليعة ماقبل الارتجاج الشديد؛ عندما كان معدل الصفائح الدموية قليل و مصاحب لارتفاع معدل انزيمات الكبد. اما المجموعة الثالثة فهن النساء اللواتي بدأن الحمل مع ارتفاع ضغط الدم ثم تطور المرض لديهن الى طليعة ماقبل الاتجاج

Abstract

ABSTRACT :BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), an immune-medaiated disorder of peripheral nerves and nerve roots. Dysautonomiais has not been studied deeply and many question not answered.OBJECTIVE:To estimate the prevalence of dysautonomia in chronic inflammatory demyelinating polyradiculoneuropathy in a group of Iraqi patients .METHODS:A cross sectional study of 23 patients fulfilled the diagnostic criteria for definite chronic inflammatory demyelinating polyradiculoneuropathy underwent autonomic function in cross sectional study which has been done in Al-Imamain Al-Kadhmiyain Medical City from December 2008 to November 2010 to detect any abnormalities in sympathetic and parasympathetic autonomic nervous systems tests. RESULT: This study includes 23 patients diagnosed with CIDP, 12 patients (52%) were male and 11 patients (48%) were females. Twenty patients had autonomic dysfunction, either clinical or subclinical or both.Eighteen of 20 patients (90%) had abnormal autonomic function tests, 16 of 20 patients (80%) symptomatic, and 14 of 20 Patients (70%) symptomatic with abnormal autonomic function tests. Abnormal autonomic function tests were found in 18 of 23 patients with CIDP (78%). In 8 patients (44%), abnormal results were limited to parasympathetic function test. Five patients (28%) abnormal results were limited to sympathetic function test. Five patients (28%) exhibited dysfunction in both systems.CONCLUSION:The findings in this study suggest high frequency of clinical and subclinical dysautonomia and parasympathetic system more likely affected than the sympathetic nervous system in patients with chronic inflammatory demyelinating polyradiculoneuropathy.

Abstract

ABSTRACT:BACKGROUND :Aphasia is a condition of Loss or impairment of the production or comprehension of spoken or written language because of an acquired lesion of the brain. Aphasia is most often caused by stroke. OBJECTIVE:To assess the relationship of post-stroke aphasia types with age, sex and stroke types PATIENTS AND METHODS:A hospital - based cross sectional survey study conducted at Baghdad teaching hospital and Al Imamain Al kadhmain medical city between October 2014 and September 2015. One hundred patients with different types of patients with proved diagnosis of stroke by clinical and radiological assessment in young age group and old one of both genders and both left and right handed were included. Data regarding the clinical and demographic characteristics of the patients were reported including: Age, gender, handedness, stroke types, stroke side, stroke site, and aphasia types.RESULTS:A total of 100 patients with different types of stroke were enrolled in this study. The mean age of the studied group was 62.1 ± 13.2 (range: 37-87) years, moreover, majority of the studied group aged more than 50 years. Females were relatively the dominant than males; 55 (55%) vs. 45 (45%) respectively. Ischemic stroke was the dominant type of stroke among cases it was reported in 76 cases (76%) compared to only 24 (24%) of hemorrhagic type. Global aphasia was found in 32 stroke cases (32%), Broca´s in 17 (17%), Thalamic 17 (17%), Putaminal 11 (11%), Werneck's 11 (11%), Motor transcortical 6 (6%), Conductive and anomia 4 (4%) and the Mixed transcortical in only two cases (2%)CONCLUSION:Post stroke Aphasia was more frequent among stroke patients older than 50 years. Ischemic stroke was the dominant type of stroke. Global aphasia was the dominant subtypes of aphasia among the studied group followed by Broca’s. Thalamic and the other subtypes were less frequent.

Abstract

Since 1959, Khalaf put up the first taxonomic key for snakes in Iraq. Until now, there are no taxonomic key for snakes in Iraq. Therefore, we have put up a new taxonomic key based on several taxonomic key from previous references  , 1959,  , Leviton et al., 1992,Mohamad, 2011, Afrasiab et al., 2013, Afrasiab and Mohamad , 2014, Amr and Disi, 2011). This keyIs a new reference for Studies and Research, where it lacks a key classification. I found new species found in Iraq such as Eryx jayakari (Boulenger, 1888), Natrix natrix (Pallas, 1814), Spalerosophis microlepis (Jan, 1865), Lytorhynchus diadema kennedyi (Schmidt, 1939), Eirenis coronelloides (Jan, 1862). Zamenis hohenackeri (Strauch, 1873), Malpolon insignitus (Geoffroyde ST- Hilaire, 1809), sub species Macrovipera lebetina obtuse (Dwinubsky, 1832), Genus: Montivipera (Nilson, Tuniyev, Andrén, Orlov, Joger & Herrmann, 1999) and sub species Montivipera raddei kurdistanica (Kucharzewski, 2011), Pseudocerastes persicus (Dumeril, Bibron & Dumerril,1854) Walterinnesia morgani (Mocquard, 1905).

Abstract

The use of image communication has increased in recent years where The rapid development of the communication network through the Internet and development of the electronic trade with spread of the digital media such as (images, audio, video) which can be got easily, copied, and distributed with another persons names. Each type of data has its own features; therefore different techniques should be used to protect confidential image data from unauthorized access. This paper has been proposed new encryption algorithm using in RGB image encryption supported by Elliptic Curve Cryptography (ECC) with forward key mixing (OFKM) process. The main advantage of elliptic curves systems is thus their high cryptographic strength relative to the size of the key. The propose scheme is simple, fast and sensitive to the secret key. The experimental results show that the proposed encryption technique is efficient and has high Security features.

Abstract

Encryption software executes an algorithm that is designed to encrypt computer data in such a way that it cannot be recovered without access to the key. Software encryption is a fundamental part of all aspects of modern computer communication and files protection. The purpose of encryption is to prevent third parties from recovering the original information. This is particularly important for sensitive data like credit card numbers. In this paper a new stream cipher, called LFSR key position, is proposed. The design of the proposed cipher is quite simple, composing two important cipher algorithms LFSR and Key position ciphers. The design goal of producing the LFSR key position stream cipher significantly depend on eliminating the weakness of both LFSR and key position ciphers through combine the two randomize factors characteristics of character position and the plain text context. The paper also explains the importance of the stream ciphers as modern class of encryption algorithms.

إن برمجيات التشفير ترتكز بشكل أساسي على تنفيذ خوارزميات تم تصميمها لتشفير بيانات الحاسوب بطريقة لا يمكن معها استرداد تلك البيانات دون الحصول على مفتاح التشفير. تُعد برامج التشفيرجزءً أساسيا في جميع جوانب الاتصالات الحاسوبية الحديثة وفي حماية الملفات بكل انواعها. إن الغرض الاساسي من عملية التشفير هو منع أي طرف ثالث متطفل من استعادة المعلومات الصريحة، حيث تكمن أهمية ذلك بشكل خاص للبيانات الحساسة مثل أرقام بطاقات الائتمان. ففي هذه الورقة نقترح طريقة تشقير تتابعية مطورة اَسميناها تشفير المسجلات التدويرية ذات التغذية الراجعة بالمفتاح الموقعي. إن تصميم طريقة التشفير المقترحة بسيط جداً، حيث تتألف من خلال دمج خوارزميتي تشفير المسجلات التدويرية ذات التغذية الراجعة و تشفير المفتاح الموقعي. وإن الهدف الاساسي من تصميم الخوارزمية هو لتلافي نقاط الضعف في كلا الخوارزميتين الاساسيتين وذلك من خلال الجمع بين عوامل التوليد العشوائي لخصائص الطريقتين من حيث موقع الحرف وسياق النص الصريح. كما يركز هذا البحث على توضيح وتبيان أهمية التشفير التتابعي كصنف حديث لخوارزميات التشفير الفعالة.
