Some researchers have reported that when parents are the main source of sex education, their adolescent chilaren are less likely to engage in premarital sexual activity and are more likely to use effective contraception. This study used the variables of gender and parental sexual attitudes (liberal or conservative) to categorize 349 college students and one of their parents into four groups. Th...

placenta increta, a rare complication of pregnancy, is associated with significant postpartum hemorrhage often requiring emergency hysterectomy. we report a case of conservative management, with a combination of parenteral methotrexate, serial ultrasound and β-hcg assessment. serum β-hcg levels were undetectable after 8 weeks of therapy. a scan at 6 months showed complete involution of the uter...

In this paper we study the scaling behavior of the interface fluctuations (roughness) for a discrete model with conservative noise on complex networks. Conservative noise is a noise which has no external flux of deposition on the surface and the whole process is due to the diffusion. It was found that in Euclidean lattices the roughness of the steady state W(s) does not depend on the system siz...

Crowdsourcing relevance judgments for test collection construction is attractive because the practice has the possibility of being more affordable than hiring high quality assessors. A problem faced by all crowdsourced judgments – even judgments formed from the consensus of multiple workers – is that there will be differences in the judgments compared to the judgments produced by high quality a...

______________________________________________________________________ In order to guarantee database consistency, a database system should synchronize operations of concurrent transactions. The database component responsible for such synchronization is the scheduler. A scheduler synchronizes operations belonging to different transactions by means of concurrency control protocols. Concurrency c...

In this paper we discuss the ergodic properties of quantum conservative systems by analyzing the behavior of two different models. Despite their intrinsic differencies they both show localization effects in analogy to the dynamical localization found in Kicked Rotator.

The flocculation of dissolved heavy metals is a process which has an important effect on decreasing the concentration of the colloidal elements during estuarine mixing of river water and sea or ocean water. During this important process, a large amount of colloidal elements change into particles in the form of flock and the dissolved loads decline. This study is performed to evaluate the mechani...
