OBJECTIVE To evaluate the efficacy of fallopian sperm perfusion (FSP) using a new method similar to the FAST system in comparison with standard intrauterine insemination (IUI) in patients with unexplained infertility. DESIGN Prospective, randomized, controlled study. SETTING Assisted conception service in a University Hospital. PATIENT(S) Women with unexplained infertility undergoing cont...

Benefit receipt in major household surveys is often underreported. This understatement has major implications for our understanding of the economic circumstances of disadvantaged populations and the distributional effects of government programs. This paper examines underreporting of food stamps by combining administrative microdata for the Food Stamp Program (FSP) and nationally representative ...

Patched 1 (Ptch1) has epithelial, stromal and systemic roles in murine mammary gland organogenesis, yet specific functions remain undefined. Cre-recombinase-mediated Ptch1 ablation in mammary epithelium increased proliferation and branching, but did not phenocopy transgenic expression of activated smoothened (SmoM2). The epithelium showed no evidence of canonical hedgehog signaling, and hyperpr...

In 1996, after two decades of increasing participation in cash and noncash public assistance programs by immigrant households (Borjas and Hilton, 1996), the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) drastically altered the availability of federal public assistance to legal immigrants but ostensibly not to refugees. Refugees were given a 5-year exemption from rules...

Background and Purpose: The epidemiological alteration in the distribution of Candida species, as well as the significantly increasing trend of either intrinsic or acquired resistance of some of these fungi highlights the need for a reliable method for the identification of the species. Polymerase chain reaction (PCR) is one of the methods facilitating the quick and precise identification of Ca...

The beneficial effect of the friction stir processing (FSP) technique for improving properties fabricated additive parts through microstructural refinement and repairing metallurgical defects has shown its ability to be integrated into a hybrid manufacturing system. In present work, conventional GMAW TIG-based processes were further post-processed with process (FSP). case + processed beads, imp...

This article present a visual characterization of facial motions inherent with speaking. We propose a set of four Facial Speech Parameters (FSP): jaw opening, lips rounding, lips closure, and lips raising, to represent the primary visual gestures of speech articulation into a multidimensional linear manifold. This manifold is initially generated as a statistical model, obtained by analyzing acc...

The important role of the electron-phonon interaction (EPI) in explaining the properties of the normal state and pairing mechanism in high-Tc superconductors (HTSC) is discussed. A number of experimental results are analyzed such as: dynamical conductivity, Raman scattering, neutron scattering, ARPES, tunnelling measurements, isotope effect and etc. They give convincing evidence that the EPI is...

In this article, we examine the impact of two universal, grade 1 preventive interventions on the onset of tobacco smoking as assessed in early adolescence. The classroom-centered (CC) intervention was designed to reduce the risk for tobacco smoking by enhancing teachers' behavior management skills in first grade and, thereby, reducing child attention problems and aggressive and shy behavior-kno...

NiAl bronze (NAB) alloy is prepared by using friction stir processing (FSP) technique at a tool rotation rate of 1200 rpm and a traverse speed of 150 mm/min. A post heat treatment is performed at the temperature of 675 °C. The effect of heat treatment on the microstructure and microhardness is studied. The results show that the microstructure of the FSP NAB alloy consists of high density disloc...
