تدور الدراسة في علم الاقتصاد المنزلي حول احتیاجات الانسان الضروریة لاستمرار الحیاة ومواقف في محیط
الاسرة وتفاعل مع ظروف البیئة المحیطة بھ .والتي تكون دائمة التغییر لذلك یمكن تعریف علوم وفنون الاقتصاد
المنزلي وفنونھ انھا عبارة عن مجموعة منظمة من المعارف والعلوم تتركز في محور الاسرة والمنزل حیث ینمو
ویتطور الانسان بالعلاقات الانسانیة والنواحي الاقتصادیة والاجتماعیة من جھة والنواحي العلمیة والفنیة الخاصة
بالغذاء من جھة اخرى فضلا عن النواحي العلمیة والفنیھ الخاصة بالمنسوجات والملابس التي تحتاجھا افراد الاسرة
لاتصالھا الوثیق بحیاتھم الیومیة . بحیث یعتقد البعض انھ لایوجد حقل من حقول المعرفة یعنى بحاجات الاسرة
المعاصرة وادارتھا اكثر مما یستطیع تخصص الاقتصاد المنزلي تقدیمھ . ذلك انھ یتنافس مع حقول المعرفة
المتنوعة بجانبیھا النظري والعملي من خلال تطوره المستمر ذو العلاقة بتطور مفردات حیاة الانسان.
إن تطور غایات الاقتصاد المنزلي لھ اھمیة في جعل الفرد یعیش في المجتمع عضواً نافعاً ویساعد غیره من
الافراد . كذلك یساعد على تنمیة المفاھیم والمھارات التي یحتاجھا الفرد في حاضره ومستقبلھ . ومن ھذا المنطلق
جاءت اھمیة تخصص الاقتصاد المنزلي عالمیاً حیث اصبح لھ اقسام وكلیات متكاملة في مختلف البلدان شرقاً وغرباً
. وفي الوطن العربي ھناك كلیات متخصصة في الاقتصاد المنزلي ویدرس بجدیة في مدارس البنات ضمن المواد
الدراسیة في مناھجھا ولھ ثُقلھ الخاص لاھمیتھ للفتیات في حیاتھن ، كما ان ھناك جمعیات عالمیة للاقتصاد المنزلي
في دول مختلفة ومشھورة عالمیاً بالدوریات التي تصدرھا وبمؤتمراتھا الفعالة .
ومع التطور الاجتماعي والتقدم العلمي والتكنولوجي تغیر نمط الحیاة وزادت اھمیة الجانب العلمي لمختلف
انشطة الحیاة . ولذلك تغیر مفھوم الاقتصاد المنزلي ومضمونھ للایفاء بالاحتیاجات الجدیدة للاسرة والمجتمع واصبح
تركیزه حالیاً على الجانب العلمي وجعل الاسرة محوراً للدراسة فضلاً عن المرونة وسھولة التكیف للتغییرات التي
تمس حیاة الاسرة والمجتمع .
Background: Feeding is a complicated process that involves the coordination of cardiovascular, respiratory, gastrointestinal (GI), and oropharyngeal mechanisms, with support from the musculoskeletal and craniofacial systems. The practice of feeding could be correlated with eruption stage and nutritional status in infants. Aim of the study: This study aimed to assess the relation of feeding patterns to a selected oral variable (stage of the eruption of primary teeth) and growth parameters among clinically healthy infants. Subjects and Methods: A cross-sectional comparative study on a sample of (300) infants aged between 6 and 18 months was performed in Karbala City, Iraq. The feeding pattern was investigated using an information sheet ans

A total of twenty-four local geese, one year old, were used in this experiment during the period from the beginning of October to the end of December. The birds were allocated for Four treatment groups consisted of six geese each. Treatment groups were as follows: Control diet (T1) (free from parsley), T2: Control diet + 80 g / d parsley, T3: Control diet + 160 g / d parsley; T4: Control diet + 240 g / d parsley. At the end of experiment, blood samples were obtained from all geese by venipuncture from brachial vein and blood plasma samples were prepared. Blood biochemical tr

This invitro study evaluated the influence of Pepsi Cola drink on the surface roughness ofComposan LCM and Composan Ceram over time. Sixteen disc shaped specimens(10mm diameter, 2mm thickness) of each resin composite were fabricated, therebyforming two groups (n= 8). Surface roughness (Ra) was analyzed after 24 hrs beforeexposure to beverage. The specimens were submitted to a five minutes immersion inPepsi Cola three times daily interrupted by immersion in deionized distilled water (37C˚). Surface roughness measurements were done at 10, 30, and 60 days intervals. Datawere

Vascular endothelial growth factor (VEGF) affects the growth of vascular endothelial cells, existence, and multiplying, which are known to be expressed in the human placenta. This study aimed to identify the expression VEGF in the placenta of hypertension and normotensive women. In this study, a cross-sectional study from november 2019 to February 2020. A total of 100 placentae involved 50 hypertensive cases and 50 normotensive groups were assessed. VEGF-A expression in two placentas groups was evaluated by immunohistochemistry techniques. Strong and moderate VEGF

The first is to study raw and treated water qualities and comparing them with standards and the second is to evaluate the treatment plants efficiency. The analyzed data were those water quality parameters in relation to physical, chemical and bacteriological characteristics for river water and produced water by seven water treatment plants located on Tigris River passing through Baghdad City.
The results of this study indicated that all raw water characteristic are within the surface water standards established by Iraqi and USA criteria except Bacterial Counts.
Tigris River water is of good quality to be trea
Experimental tests were carried to control lost circulation in the Khabaz oil field using different types of LCMs including Nano-materials. A closed-loop circulation system was built to simulate the process of lost circulation into formations. Two dolomite plugs were used from different depths of the formation of Azkand in Khabaz oil field. The experimentations were carried out to study the effect of different types of LCMs, cross-linked copolymer (FLOSORB CE 300 S), SiO2 NP, and Fe2O3 NP, on mud volume losses as a function of time.
The rheological measurements of the nanoparticles-reference mud system showed that both of the SiO2 NP and Fe2O3 NP w

Sixty adult rats of both sexes were used in this study; the animals were randomly enrolled into six groups of 10 animals each. Group I: negative control (rats administered distilled water); Group II: Menaquinones-7 at a dose of 16 µg/kg; Group III: Menaquinones-7 at a dose of 48 µg/kg; Group IV: positive control (Doxorubicin 15 mg/kg); Group V: Menaquinones-7 at a dose of 16 µg/kg administered prior to a single dose of Doxorubicin 15 mg/kg; Group VI: Menaquinones-7 at a dose of 48 µg/kg administered prior to a single dose of Doxorubicin 15 mg/kg. On day twelve of the study, blood was
... Show MoreMethotrexate (MTX) is a folate antagonist widely used in the treatment of neoplastic diseases; its biotransformation in the liver produced active metabolites that promote hepatotoxicity. The present study was designed to evaluate the hepatoprotective effect of aqueous extract of Camellia sinensis (Green tea) against MTX-induced liver damage in rats. A model of liver injury in rats was induced by intraperitoneal injection of 20mg/kg MTX as a single dose followed by saline and 1.25% and 2.5% aqueous extract of green tea (GTE) were orally administered 7 days prior and 5 days after MTX-intoxication as a sole source of drinking water. After killing the animals, blood samples were obtained for evaluation of serum levels of alanine and
