asked Feb 17, 2019 in Psychology by anna54. The donor–recipient model is useful in evaluating oocyte quality. (, Remohí, J., Gartner, B., Gallardo, E. et al. Perhaps the most important feature of resistant varieties is the stabilizing effect they have on production and hence on steady food supplies. One child creates a story and whispers it to a second child, who does the same to a third child, and so on. Cyberneticist Ron Eglash has suggested that fractal geometry and mathematics are prevalent in African art , games, divination , trade, and architecture. Our editors will review what you’ve submitted and determine whether to revise the article. The eta2 measures the magnitude of the effect (COS repetition) on the evaluated parameters. Distribution and maintenance of new varieties, https://www.britannica.com/science/plant-breeding, The New York Times- Useful Mutants, Bred With Radiation. Decalcomania, a technique used by artists such as Max Ernst, can produce fractal-like patterns. The plant breeder usually has in mind an ideal plant that combines a maximum number of desirable characteristics. To assess oocyte quality through repeated cycles of COS, we chose to study donors who had five consecutive cycles (n = 43), in order to preserve the statistical power of the analysis (minimum number required = 30) through an intra-group analysis.

The same participants remembering some information at longer and longer intervals after learning the information. In some species buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas. See examples from your HSC texts here. Of these, 1466 (87.1%) led to an embryo transfer. The oocyte quality, assessed as fertilization, implantation and pregnancy rates, was similar through five repeated controlled ovarian stimulation cycles. Breeding programmes can be improved and optimised through the use of reproductive techniques. Increasing similarity between "fillers" and a suspect leads to an increased level of missed identification of guilty suspects. The repeated reproduction technique used in memory studies involves a. the same participants remembering some information at longer and longer intervals after learning the information. Follicle development up to the antral stage is gonadotrophin independent, and only the last two weeks of this long trajectory are gonadotrophin dependent (Fauser and Van Heusden, 1997). Briefly, a long protocol for pituitary desensitization was carried out, with daily administration of 1 mg s.c. leuprolide acetate (Procrin; Abbott Laboratories, Madrid, Spain) starting in the luteal phase of the previous cycle. One of the aims of virtually every breeding project is to increase yield. [Development of a Coping Scale for Infertility-Women (CSI-W)]. Thus the breeder can rarely focus attention on any one characteristic but must take into account the manifold traits that make the plant more useful in fulfilling the purpose for which it is grown. Obtained greater forgetting and false recall with serial reproduction. Unconscious plagiarism of the work of others is known as, The repeated reproduction technique used in memory studies involves. No significant difference was observed in the number of retrieved oocytes up to nine consecutive cycles of COS in the same donor, even after statistically annulling the differences in days of stimulation, gonadotrophin dose, days of GnRH agonist analogue use, and interval in days between cycles. b. different groups of participants remembering some information across different periods of time after learning the information. B. different groups of participants remembering some information across different periods of time after learning the information. Of the women, 136 were nulliparous (47.9%), while 148 had had at least one pregnancy. Mendel's law of segregationCross of a purple-flowered and a white-flowered strain of peas. They were informed of the risks associated with COS and oocyte retrieval procedures, and signed a written agreement. Our results show that the length of the interval has no effect on the outcome of COS. Each donor programme must develop strategies in order to follow these women, after their donation, for a long time. The distribution of semen characteristics in the recipients group was assessed by a χ2 with Monte Carlo method. The utility of nuclear magnetic resonance spectroscopy in assisted reproduction. Extrapolating from the cultural life script hypothesis, which of the following events would be east to recall? The results of early plant-breeding procedures were conspicuous. (, Ahmed Ebbiary, N.A., Morgan, C., Martin, K. et al. Outcomes in recipients from oocytes donated through five consecutive COS cycles (mean ± SD), Retrieved oocytes and recipients' outcome of 35 donors who had their second COS cycle <90 days from the first, and the third COS cycles ≥90 days from the second (mean ± SD). Repetition is a very common technique used by composers and it is easily identified. For example, it is possible to breed varieties of corn (maize) much higher in lysine than previously existing varieties. HCG (Profasi, Serono Laboratories, Madrid, Spain) 10 000 IU i.m. Plant breeding, application of genetic principles to produce plants that are more useful to humans. Budding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. Bartlett (1932) based these conclusions on naturalistic studies that used two primary techniques: Repeated reproduction and serial reproduction. METHODS AND RESULTS: Between March 1994 and February 2000, 284 donors consented to at least two controlled ovarian stimulation cycles, with four donors undergoing up to nine cycles.

Using output bound scoring, serial reproduction resulted in lower accuracy than repeated reproduction by the final recall trial. A progressive decrease of ovarian response in women with ovarian endometriosis was found, whereas, in women with tubal infertility, repeated COS had no influence (Al-Azemi et al., 2000). In all the analysis, the assumed sphericity was verified by the Mauchly test, that is, to assure that no data overlapping is present in the statistical analysis. (, Al-Azemi, M., Bernal, A.L., Steele, J. et al. (, Ron-El, R., Raziel, A., Herman, A. et al. In the literature there is not enough coverage about the influence of the interval between consecutive cycles of COS. Studies on consecutive versus alternating cycles of ovarian stimulation using HMG for intercourse or intra-uterine inseminations found more pregnancies in women stimulated in consecutive than in alternating cycles (Silverberg et al, 1992). Recall of the initial study list words remained constant across repeated reproductions but declined markedly across serial reproductions. Directly compared Bartlett's procedures of serial and repeated reproduction. Some of these donors are treated with consecutive COS cycles, with different intervals of time between stimulations. Our aim was to assess the effect of multiple COS on oocyte retrieval rate, as well as the oocyte's quality, reflected by the recipient's outcome. Because more of the original list words were forgotten across each link of the serial reproduction chain, the proportion of critical items recalled (relative to list words) increased significantly as the list passed between people. The mean interval between cycles was 174 ± 139 days, with a minimum interval of 45 days, a maximum of 1166, and a median of 119 days. Results showed that the misinformation effect was greatest when presentation of misleading post-event information was: In the experiment in which participants sat in an office and then were asked to remember what they saw in the office, participants "remembered" some things, like books, that weren't actually there. Repeated reproduction The use of repeated reproduction has led to much less consis-tency. After 32 weeks, participants had a high level of confidence in their memories of the terrorist events, but lower belief in their memories of "everyday" events. Mean age was 24.9 years (standard deviation 4.2). Rather, it provides an overriding mechanism by which many follicles destined to become atretic escape from this end (Schipper et al., 1998). After an intra-group analysis of the recipients' cycles of the 43 donors with five stimulations, no differences were found in fertilization, implantation and pregnancy rates according to the oocyte's cycle origin.
