در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Amniotic fluid cells; prenatal sex prediction and culture.

Sex chromatin studies were carried out on small amounts of amniotic fluid obtained by amniocentesis or from intact amniotic sacs removed at hysterotomy. Provided that satisfactory preparations were obtained the accuracy of fetal sexing was 87%. Nevertheless, in the management of a pregnancy in which there is a risk of a serious X-linked recessive disorder, repeat amniocentesis may be necessary ...

Prenatal diagnosis of homozygous alpha thalassaemia by direct DNA analysis of uncultured amniotic fluid cells.

Prenatal diagnosis of homozygous alpha thalassaemia was performed in eight successive patients at risk using DNA from uncultured amniotic fluid cells. The presence of alpha gene was determined by restriction endonuclease mapping and hybridisation with cloned alpha and beta globin probes. This method is reliable and may be performed at 16 weeks of gestation.

Cytological study of amniotic fluid for prenatal sex determination.

A method for determining fetal sex by identification of Barr-Body in amniotic fluid by staining with aceto-orcein 120 patients pregnant for 20-40 weeks (Group 1) and 50 patients pregnant for 14-20 weeks (Group 2). The results were confirmed at birth or abortion. The accuracy of fetal sex diagnosis was 98.33% in Group 1 and 100% in Group 2. The method is extremely rapid, requiring no more tha...
