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 .
This work aimed to use conventional PCR to identify Salmonella spp. that were isolated from diarrheal children and healthy and diarrheic dogs based on four virulence genes, hilA, stn, spvR, and marT. Sixteen Salmonella isolates including: 9 isolated from children's diarrhea from three species (S. Typhimurium, S. Enteritidis, S. Typhi) and seven isolated from dogs including (S. Typhimurium, S. Enteritidis, S. Muenchen), were identified primarily by several methods. The PCR products of the 16S rRNA gene were sequenced and examined using BLAST analysis to find differences and similarities between these Iraqi isolates and already-known global strains in order to construct the phylogenetic tree of S.
... Show MoreA total number of 68 water samples was revealed 20 isolates being Staphylococcus aureus. Irrigation water isolates represented 25% of isolates while wastewater 75%. all isolates were identified by morphological, microscopial, biochemical tests and VITEK®2 Compact. Bacterial isolates were subjected to 16 antibiotics, all irrigation water and wastewater isolates were resistant to penicillin while they were fully sensitive to Ciprofloxcin. Irrigation water isolates showed relatively greater multi-drug resistance than wastewater, wherein irrigation water isolates showed 100% multi-drug resistance while wastewater isolates showed 73.3% multi-drug resistance, indicating the ability of S. aureus MDR to move from one site to another, which means t
... Show MoreThis study compared in vitro the microleakage of a new low shrink silorane-based posterior composite (Filtek™ P90) and two methacrylate-based composites: a packable posterior composite (Filtek™ P60) and a nanofill composite (Filtek™ Supreme XT) through dye penetration test. Thirty sound human upper premolars were used in this study. Standardized class V cavities were prepared at the buccal surface of each tooth. The teeth were then divided into three groups of ten teeth each: (Group 1: restored with Filtek™ P90, Group 2: restored with Filtek™ P60, and Group 3: restored with Filtek™ Supreme XT). Each composite system was used according to the manufacturer's instructions with their corresponding adhesive systems. The teeth were th

Saliva is critical for preserving and maintaining oral health and salivary elements had many effects on caries experience. Aim of study: This study was conducted to assess dental caries severity by age and gender and their relation to salivary zinc and copper among a group of adults aged (19-22) years. Materials and methods: After examination eighty persons aged 19-22 years of both gender. Caries severity was documented according to DMFS index. Stimulated salivary samples were collected and chemically analyzed under standardized condition to detect salivary elements zinc and copper. Concentrations of Zinc and copper were measured by using
... Show MoreA field experiment was carried out during the spring season 2019 and 2020 to obtain a fast, uniform, and high field emergence ratio of maize seeds under a wide range of environmental conditions. Randomize complete block design in the split-plot arrangement was used with three replications. The first factor in the main plots was cultivars (5018, Baghdad3 and Sumer). The second factor in the sub-plots was seeds soaking with ascorbic and citric acids (100 mg L−1) each and humic (1 ml L−1) in addition to control treatment (seeds soaking with distilled water only). Results showed the superiority of soaking with humic acid significantly, as means of characteristics of field emergence in both seasons, respectively, were as follows: Last day of
... Show MoreA case-control study was performed to examine age, gender, and ABO blood groups in 1014 Iraqi hospitalized cases with Coronavirus disease 2019 (COVID-19) and 901 blood donors (control group). The infection was molecularly diagnosed by detecting coronavirus RNA in nasal swabs of patients.
Mean age was significantly elevated in cases compared to controls (48.2 ± 13.8
Simple and sensitive batch and Flow-injection spectrophotometric methods for the determination of Procaine HCl in pure form and in injections were proposed. These methods were based on a diazotization reaction of procaine HCl with sodium nitrite and hydrochloric acid to form diazonium salt, which is coupled with chromatropic acid in alkaline medium to form an intense pink water-soluble dye that is stable and has a maximum absorption at 508 nm. A graphs of absorbance versus concentration show that Beer’s law is obeyed over the concentration range of 1-40 and 5-400 µg.ml-1 of Procaine HCl, with detection limits of 0.874 and 3.75 µg.ml-1 of Procaine HCl for batch and FIA methods respectively. The FIA average sample throughput was 70 h-1. A

The study involved the detection of serum anti-H. pylori IgG and IgA antibody of and some serum biomarkers ;CEA and CA19-9 in patients with gastrointestinal diseases. Fifty eight serum samples were collected from 25 males and 33 females .Peripheral venous blood was collected from each patient and sera obtained by centrifugation. Serum anti-H. pylori IgG and IgA ,serum CEA and CA19-9 were evaluated by enzyme-linked immunoadsorbent assays (ELISA).Forty eight serum samples were positive for IgG (82.7% ) divided int
