it emphasizes the application of statistical methods to the small groups of variable data which are commonly available to the worker in biological fields. The first part of the book describes the theoretical bases of statistical interpretation , the dassic frequency distributions, and the relationships between variables. In the second part are discussed problems of sampling, estimation of param...

To determine the effect of local endometrial injury on implantation success in patients diagnosed with unexplained infertility and undergoing intrauterine insemination (IUI) after ovulation induction gonadotropins. In this prospective randomized controlled trial, 82 infertile underwent IUI following gonadotropin. study group (n:40), (stratch) was performed to posterior side cavity a biopsy cath...

Some religious rites of Hajj (the obligatory pilgrimage that many Muslims make to Mecca) cannot be performed during menstruation, so women may wish to suppress their menses. Eliminating monthly periods could further improve the quality of women’s lives, reducing both physical pain and mood swings that can be disruptive or debilitating, to say nothing of the inconvenience and cost of managing mo...

We report two patients with epilepsy with pseudoseizures at age 6 years. Both presented with intractable staring spells. Pseudoseizures were provoked and aborted by suggestion, leading to the diagnosis. In both patients, evidence of a neuropsychological disturbance was later found and psychotherapy started. Monitoring of intractable staring episodes is recommended prior to escalating antiepilep...

Habitat destruction, often caused by anthropogenic disturbance, can lead to the extinction of species at an unprecedented rate. It is important, therefore, to consider habitat destruction when assessing population viability. Another factor often ignored in population viability analysis, is the Allee effect that adds to the risk of populations already on the verge of extinction. Understanding th...

BACKGROUND Social cognitive theories on behaviour change are increasingly being used to understand and predict healthcare professionals' intentions and clinical behaviours. Although these theories offer important insights into how new behaviours are initiated, they provide an incomplete account of how changes in clinical practice occur by failing to consider the role of cue-contingent habits. T...

BACKGROUND Problematic Internet use in adolescents has become an issue of concern for a growing number of researchers and institutions over the past years. Behavioural problems, social isolation, school failure and family problems are some of the consequences of psychological and behavioural impact on teenagers. Taking into account the interest that this issue has generated at many levels, the ...

This paper analyzes the marginal willingness to pay for changes in noise levels related to changes in the volume of flight movements at a city airport in Stockholm, Sweden, by using a choice experiment. When estimating marginal willingness to pay for different times of the day and days of the week, we find that these vary with the temporal dimensions: mornings and evenings have higher marginal ...

Predicting community and species responses to disturbance is complicated by incomplete knowledge about species traits. A phylogenetic framework should partially solve this problem, as trait similarity is generally correlated with species relatedness, closely related species should have similar sensitivities to disturbance. Disturbance should thus result in community assemblages of closely relat...
