Direct numerical simulations of interface dynamics to link capillary pressure and total surface energy

The flow of two immiscible fluids through a porous medium depends on the complex interplay between gravity, capillarity, and viscous forces. The interaction between these forces and the geometry of the medium gives rise to a variety of complex flow regimes that are difficult to describe using continuum models. Although a number of pore-scale models have been employed, a careful investigation of the macroscopic effects of pore-scale processes requires methods based on conservation principles in order to reduce the number of modeling assumptions. In this work we perform direct numerical simulations of drainage by solving Navier-Stokes equations in the pore space and employing the Volume Of Fluid (VOF) method to track the evolution of the fluid-fluid interface. After demonstrating that the method is able to deal with large viscosity contrasts and model the transition from stable flow to viscous fingering, we focus on the macroscopic capillary pressure and we compare different definitions of this quantity under quasi-static and dynamic conditions. We show that the difference between the intrinsic phase-average pressures, which is commonly used as definition of Darcy-scale capillary pressure, is subject to several limitations and it is not accurate in presence of viscous effects or trapping. In contrast, a definition based on the variation of the total surface energy provides an accurate estimate of the macroscopic capillary pressure. This definition, which links the capillary pressure to its physical origin, allows a better separation of viscous effects and does not depend on the presence of trapped fluid clusters.

Prevalence and dimensions of sexual orientation in Swiss adolescents: a cross-sectional survey of 16 to 20-year-old students.

AIM: Sexual orientation plays an important part in building identity during adolescence. The aim of this study was to describe patterns of sexual orientation, including sexual attraction, fantasies, affiliations and behaviour. METHODS: The study was based on the analysis of data from computerized self-administered questionnaires of a Swiss national survey on the sexual life of 16 to 20-year-old adolescents (n = 2,075 girls and 2,208 boys.). RESULTS: Overall, 95.0% of girls and 96.2% of boys described themselves as predominantly heterosexual; 1.4% of girls and 1.7% of boys as predominantly homosexual or bisexual; and 2.8% of teenagers (girls: 3.6%; boys: 2.1%) were "unsure" of their sexual orientation. The reported prevalence of homosexual attraction (girls: 2.0%; boys: 2.9%) exceeded homosexual fantasies (girls: 0.4%; boys: 0.5%) and affiliations (girls: 0.3%; boys: 0.5%). Among the 4205 respondents, 31 girls (1.5% of girls) and 56 boys (2.5% of boys) reported sexual behaviour (experience or penetrative intercourse) with a person of the same sex. Among 1.5% of girls and 2.5% of boys who reported sexual behaviour with a person of the same sex, 65% of boys and 80% of girls nevertheless considered themselves as heterosexual. CONCLUSION: For a comprehensive understanding of sexual orientation in adolescence a differentiated look at dimensions of sexual orientation is indispensable. This applies to clinical settings, public health and research.

2015-16 Student Loan Repayment and Forgiveness Programs

Many loan repayment and incentive programs are available to encourage college students and graduates to enter into and continue to work in designated high-need careers. More and more Iowans are reaping the rewards of these federal, state and private programs that help reduce student loan debt while allowing them to pursue their career goals. Some programs make payments directly to the recipient’s student loan servicer to reduce the balance owed (loan repayment), while others may provide the option of an income stipend or bonus for eligible recipients who meet specified employment and other criteria. This guide provides information on many of the federal and state loan repayment and incentive programs currently available.

How to Apply for Financial Aid: A Guide for Students (2015-16)

Paying for college doesn’t have to be financially overwhelming. There are several types of aid, including federal, state and institutional grants; scholarships from numerous sources; college savings plans; student and parent loans; and student employment options available to help you pay for college. In fact, most students attending Iowa colleges and universities receive some form of financial assistance. To be considered for most financial aid programs, you must complete the Free Application for Federal Student Aid (FAFSA). Applying for admission is not the same as applying for financial aid - you need to do both. To receive financial aid, it is necessary to file a completed FAFSA and submit an admissions application to the colleges and universities that interest you most. Follow the steps in this brochure to be considered for funds from the state of Iowa, the federal government and the colleges or universities of your choice.
