1. Crosses between wild type (dark ascospores) and the asco-mutant (light ascospores) were set up and the spores collected as unordered octads. The analysis of 1317 such octads revealed 69 with abnormal segregation of the asco-marker (5.2%). If crosses were irradiated with UV at a dose equivalent to 66% conidial killing, an increase of the number of aberrant octads was found. This increase was ...
Aim. To evaluate the effectiveness and the tolerability of the nitrous oxide sedation for dental treatment on a large pediatric sample constituting precooperative, fearful, and disabled patients. Methods. 472 noncooperating patients (aged 4 to 17) were treated under conscious sedation. The following data were calculated: average age; gender distribution; success/failure; adverse effects; number...
Objective: The role of anesthesia in maternal mortality is unknown the Democratic Republic Congo (DRC). This study was conducted with objective analyzing determinants morbidity and linked to course cesarean section. Methods: a prospective, analytical mono-centric carried out on women who underwent section at Centre Hospitalier Mère-Enfant Monkole from January 1st, 2011 December 31st, 2018. vari...
با توجه به افزایش سریع جمعیت کشور، نیاز به تولید بیشتر محصولات کشاورزی بیش از پیش در جامعه احساس میشود. اما افزایش تولیدد همیشه یا با افزایش سطح زیر کشت و یا با مصرف هر چه بیشتر سموم و کودهای شیمیایی همراه بوده است. به دلیل اید کده اسدتااده از سموم و کودهای شیمیایی میتواند خطرات جدی برای محیط و سلامت جامعه ایجاد نماید. هدف از مطالعده حاضدر ، تعیدی الگدوی بهینده کشت محصولات کشاورزی، با...
با مفقود شدن سند مالکیت، واکنش منطقی مالک درخواست صدور المثنی سند مالکیت از ادارة ثبت اسناد و املاک محل وقوع ملک است. اما، با توجه به استفادة روزافزون سازمان ثبت اسناد و املاک کشور از نرمافزارهای رایانهای و صدور اسناد مالکیت به صورت تکبرگ و از سوی دیگر تدوین مادة 120 آییننامة قانون ثبت در سال 1317 و اصلاح آن در سال 1380، چالشهایی برای واحدهای ثبتی ایجاد شده است. در این تحقیق، که به شیوة تو...
A novel hierarchical neural network architecture for sensory-motor learning and behavior generation is proposed. Two levels of forward model neural networks are operated on different time scales while parametric interactions are allowed between the two network levels in the bottom-up and top-down directions. The models are examined through experiments of behavior learning and generation using a...
The framing effect refers the tendency to be risk-averse when options are presented positively but be risk-seeking when the same options are presented negatively during decision-making. This effect has been found to be modulated by the serotonin transporter gene (SLC6A4) and the catechol-o-methyltransferase gene (COMT) polymorphisms, which are on the dopaminergic and serotonergic pathways and w...
The boron abundances for two young solar-type members of the Orion association, BD -6 1250 and HD294297, are derived from HST STIS spectra of the B I transition at 2496.771 Å. The best-fit boron abundances for the target stars are 0.13 and 0.44 dex lower than the solar meteoritic value of log ǫ(B)=2.78. An anticorrelation of boron and oxygen is found for Orion when these results are added to pr...
The quality factor (Q), mode volume (V(eff)), and room-temperature lasing threshold of microdisk cavities with embedded quantum dots (QDs) are investigated. Finite element method simulations of standing wave modes within the microdisk reveal that Veff can be as small as 2(lambda/n)(3) while maintaining radiation-limited Qs in excess of 10(5). Microdisks of diameter 2 microm are fabricated in an...
We argue that the series of traits characterizing Borderline Personality Disorder samples do not weigh equally. In this regard, we believe that network approaches employed recently in Personality and Psychopathology research to provide information about the differential relationships among symptoms would be useful to test our claim. To our knowledge, this approach has never been applied to pers...
