التلوث البيئي ومخاوف المرآة من الانجاب
...Show More Authors

         أن نظرة المرأة اليوم نحو الحمل والانجاب قد تغيرت نتيجة بعض العوامل وكان التلوث البيئي من أكثر العوامل تأثيرآ ، لانه يمثل أكثر الاخطار التي تبيد الجنس البشري وتقطع جذوره وتهدم سلالته الاصليه من خلال عملية التغاير في الجينات الوراثية وانتقالها عبر الاجيال . وأن أثاره لم تقتصر على الجانب الصحي للأم بل تعداه الى الجانب النفسي فاتجاهات الامهات اليوم نحو الحمل والانجاب ليس كما هو في السابق أذ تراجع درجات ودرجات بسبب خوفها من الفشل من ولادة طفل طبيعي خالي من التشوهات الخلقية . لذا فقد هدف البحث الحالي الى الاجابة على الاسئلة الاتيه :

  • هل يختلف عدد الاطفال باختلاف مستويات التحصيل الدراسي للام ؟
  • هل يختلف عدد الاطفال باختلاف مهنة الام (عاملة أو غير عاملة ) ؟
  • هل يختلف عدد الاطفال باختلاف عدد سنوات زواج الام ؟
  • هل يوجد فرق بين عدد الاطفال الحالي (الفعلي ) والمفضل عند الامهات ؟
  • هل يوجد فرق بين مستويات تحصيل الامهات في درجة الخوف من الانجاب؟
  • هل يوجد فرق بين الفئات العمرية للامهات في درجة الخوف من الانجاب ؟
  • هل يوجد فرق بين مهنة الام في درجة الخوف من الانجاب ؟
  • ما هي أكثر الاسباب التي تثير مخاوف المرآه من الانجاب ؟

      تكون مجتمع البحث من الامهات المتواجد ات في مستشفى اليرموك واللواتي في سن الانجاب الامثل من عمر (20-35) سنة ،أن عينة البحث (115) أم أختيرت عشوائيآ من المستشفى . واعتمدت الباحثة على الدراسات السابقه والادبيات واراء بعض المختصين في الصحة وعلم النفس في بناء اداة البحث وكان مجموع الفقرات النهائي (15) فقرة واستخرجت الباحثة الصدق والثبات والتمييز ، أستخدام (تحليل التباين ، النسبة المئويه ,الاختبار الزائي ) كوسيلة احصائية . واسفرت النتائج عما يأتي :

1-أن عدد الاطفال لايختلف باختلاف (التحصيل الدراسي ، المهنه ، عدد سنوات الزواج ) للامهات ، وكل هذه المتغيرات حصلت على أعلى نسبه لاعداد الاطفال من  ( 1-2 ) طفل ،واقل نسبة لاعداد الاطفال من (5) فاكثر  .

2- هناك فرق ذات دلالة احصائيه بين عدد الاطفال الفعلي (الحالي ) والمفضل للامهات  .

3- لايوجد فرق ذات دلاله احصائيه بين الفئات العمريه للامهات في درجة الخوف من الانجاب .

4- يوجد فرق دال احصائيآ بين الامهات في درجة الخوف من الانجاب  .

5- اعلى نسبه اتفاق حصلت عليها الامهات على الاسباب كانت :

    أ- خوفآ من التلوث نتيجة الضربات الامريكيه الصاروخيه  .

  ب- تلوث مصادر مياه الشرب  .

  ج- تلوث الغذاء  .

 واستنادآ الى هذه النتائج وضعت الباحثة بعض التوصيات والمقترحات .

Vatan ve hürriyet aşkının ilk ve en Kuvvetli örneklerinden Türkmen topraklarında yetişen yüzlerce Şairlerden biri Hıdır Lütfü’dür. Düşmana yar, öz evladına ağyar, yumuşak tabiatlı, yardımı ve milletini seven bir insandır. Şairin duygusu her dem yükseklere yücelirdi. O bilgili bir şair olduğu için şiirinde türlü türlü bilgi ile ögütleri arkasında bırakmamış onun duygusu bir bulak gibi her dem durmadan coşardı.
Onun en çok sevdiği varlıklar yurdu ile ulusuydı, ve tek acısı onların ilerleme ile yükselemesi içın bir haykırıydı.
Şair her zaman yurdunun ufukunda dolaşıp ulusunun bugünkü ve geleck torunları için yanıklı duyguları ile bir yol gosterıci gibi olmuştur.

Preparation of Light Fuel Fractions from Heavy Vacuum Gas Oil by Thermal Cracking Reaction
...Show More Authors

This work deals with thermal cracking of heavy vacuum gas oil which produced from the top of vacuum distillation unit at Al- DURA refinery, by continuous process. An experimental laboratory plant scale was constructed in laboratories of chemical engineering department, Al-Nahrain University and Baghdad University. The thermal cracking process was carried out at temperature ranges between 460-560oC and atmospheric pressure with liquid hourly space velocity (LHSV) equal to 15hr-1.The liquid product from thermal cracking unit was distilled by atmospheric distillation device according to ASTM D-86 in order to achieve two fractions, below 220oC as a gasoline fraction and above 220oC as light cycle o

Study of NOx Emissions of S.I. Engine Fueled with Different Kinds of Hydrocarbon Fuels and Hydrogen
...Show More Authors

 

      Liquefied petroleum gas (LPG), Natural gas (NG) and hydrogen were used to operate spark ignition internal combustion engine Ricardo E6, to compare NOx emissions emitted from the engine, with that emitted from engine fueled with gasoline as a fuel.

      The study was done when engine operated at HUCR for gasoline, compared with its operation at HUCR for each fuel. Compression ratio, equivalence ratio and spark timing were studied at constant speed 25rps.

The results appeared that NOx concentrations will be at maximum value in the lean side near the stoichiometric ratio, and reduced with moving away from this ratio for mixture at both s

Lambs were divided in to (3) groups (9 lambs/group). Control group was fed on (85% barely، 10% bran and 5% straw)، and second and third groups were fed on various by-product in replacement with barely in loss and block shape respectively.

Differentiation of Adipose-Derived Mesenchymal Stem Cells into Neuron-Like Cells induced by using β-mercaptoethanol
...Show More Authors

Background: Adipose derived-mesenchymal stem cells have been used as an alternative to bone marrow cells in this study. Objective: We investigated the in vitro isolation, identification, and differentiation of stem cells into neuron cells, in order to produce neuron cells via cell culture, which would be useful in nerve injury treatment. Method: Mouse adipose mesenchymal stem cells were dissected from the abdominal subcutaneous region. Neural differentiation was induced using β-mercaptoethanol. This study included two different neural stage markers, i.e. nestin and neurofilament light-chain, to detect immature and mature neurons, respectively. Results: The immunocytochemistry results showed that the use of β-mercaptoethanol resulted in

Reliability and Failure Probability Functions of the m-Consecutive-k-out-of-n: F Linear and Circular Systems
...Show More Authors

The m-consecutive-k-out-of-n: F linear and circular system consists of n sequentially connected components; the components are ordered on a line or a circle; it fails if there are at least m non-overlapping runs of consecutive-k failed components. This paper proposes the reliability and failure probability functions for both linearly and circularly m-consecutive-k-out-of-n: F systems. More precisely, the failure states of the system components are separated into two collections (the working and the failure collections); where each one is defined as a collection of finite mutual disjoint classes of the system states. Illustrative example is provided.

The Optical Limiting Behaviour of Prepared Silver Nanoparticles Embedded in Polymer Film
...Show More Authors

In the present work, silver nanoparticles were prepared. Nonlinear optical properties and
optical limiting of silver nanoparticles were investigated.Standard chemical synthesis method was used at
diffrent weight ratio(0.038, 0.058 and 0.078) of silver nitrate. Several testing were done to obtain the
characteristics of the sample. Z-Scan experiments were performed using 30 ns Q-switched Nd:YAG
laser at 1064 nm and 532 nm at different intensities. The results showed that the nonlinear refractive
index is directly proportional to the input intensities, which caused by the self-focusing of the material.
In addition, the optical limiting behavior has been studied. The results showed that the sample could be
used as an opt
