abstract nowadays, with the partial achievement of the global village together with the hegemonic role based on western technology, the culture and of course the style of writing of developing countries (like our own), are at risk of being threatened. in order to maintain their style of writing, these countries must analyze their style and with the help of pathology and by keeping it up to date...

The Drosophila EGF receptor is required for differentiation of many cell types during eye development. We have used mosaic analysis with definitive null mutations to analyze the effects of complete absence of EGFR, Ras or Raf proteins during eye development. The Egfr, ras and raf genes are each found to be essential for recruitment of R1-R7 cells. In addition Egfr is autonomously required for M...

n Contemporary studies indicate that teen pregnancy interferes with young women’s ability to graduate from high school and to enroll in and graduate from college. Conversely, planning, delaying and spacing births appears to help women achieve their education and career goals. Delaying a birth can also reduce the gap in pay that typically exists between working mothers and their childless peers ...

Adults are expert at recognizing faces, in part because of exquisite sensitivity to the spacing of facial features. Children are poorer than adults at recognizing facial identity and less sensitive to spacing differences. Here we examined the specificity of the immaturity by comparing the ability of 8-year-olds, 14-year-olds, and adults to discriminate houses differing in the spacing between fe...

Thirty-five individuals who had learned and relearaed 50 English-Spanish word pairs were tested for recall and recognition after an interval of 8 years. Two variables, the spacing between successive releaming sessions and the number of presentations required to encode individual word pairs, are excellent predictors of the likelihood of achieving permastore retention. Optimum recall occurs for w...
