    This community medical clinic will be the first of its kind in the rural town of Villa Tapia, Dominican Republic It is Phase II of a five-phase master plan drafted by religious organization Mission Twenty-Five35, founded by the Romano family The team consists of Cal Poly undergraduate students: Griffin Chierici (Architecture), Erica Croft and Tommy Sidebottom (Architectural Engineering), and Sarah De Los Reyes (Construction Management), backed by the guidance and support of non-profit organization Journeyman International and A/E firm Smith Group JJR The task was to design a clinic that would serve as a pediatric and urgent care center but also a place for education The main goal is sustainability, using solar panels and passive heating and cooling just to name a few Concrete masonry, steal, and brick make up most of the building elements, with an emphasis of recycled material through the design of a gabion wall In a location that is prone to earthquakes and hurricanes, it is just as important that this building can withstand great lateral forces too Overall, the clinic will provide much needed help in the region where currently the ill need to travel to the island\u27s capital for care

    Revisiting the Integrated Star Formation Law. I. Non-starbursting Galaxies

    We use new and updated gas- and dust-corrected star formation rate (SFR) surface densities to revisit the integrated star formation law for local "quiescent" spiral, dwarf, and low surface brightness galaxies. Using UV-based SFRs with individual IR-based dust corrections, we find that "normal" spiral galaxies alone define a tight Σ_(H I + H2)–Σ_(SFR) relation described by an n = 1.41^(+0.07)_(-0.07) power law with a dispersion of 0.28^(+0.02)_(-0.02) (errors reflect fitting and statistical uncertainties). The SFR surface densities are only weakly correlated with H I surface densities alone, exhibiting a stronger and roughly linear correlation with H2 surface densities, similar to what is seen in spatially resolved measurements of disks. However, many dwarf galaxies lie below the star formation law defined by spirals, suggesting a low-density threshold in the integrated star formation law. We consider alternative scaling laws that better describe both spirals and dwarfs. Our improved measurement precision also allows us to determine that much of the scatter in the star formation law is intrinsic, and we search for correlations between this intrinsic scatter and secondary physical parameters. We find that dwarf galaxies exhibit second-order correlations with the total gas fraction, stellar mass surface density, and dynamical time, which may explain much of the scatter in the star formation law. Finally, we discuss various systematic uncertainties that should be kept in mind when interpreting any study of the star formation law, particularly the X(CO) conversion factor and the diameter chosen to define the star-forming disk in a galaxy
