Lymph nodes go with the flow

In this issue, Bovay et al. (https://doi.org/10.1084/jem.20180217) invoke a compelling model of interplay between the venous and lymphatic vasculature in regulating the developmental genesis and early expansion of LNs. This work supports an emerging model that lymph-venous crosstalk supports LN functionality at all stages

Civic Contributions: Taxes Paid by Immigrants in the Washington, DC, Metropolitan Area

This report estimates the taxes paid by immigrants in the Washington, D.C., area in 1999-2000 and documents their demographics, household composition, income, and dispersal across jurisdictions in the region. The findings in this report are based mostly on analysis of 2000 U.S. Census data, because the census provides the most recent comprehensive data that allow disaggregation by country of origin groups and by many of the region's local jurisdictions. The demographic data in the report are updated through 2004 using the U.S. Current Population Survey. We calculate taxes at both the individual level (e.g., income and payroll taxes) and the household level (e.g., property taxes), but aggregate them up to the household level. Throughout the report we refer to households headed by immigrants (whether citizens, legal immigrants, or unauthorized migrants) as "immigrant households" and compare their incomes and tax payments to households headed by native-born U.S. citizens

Application of Low Speed Wind Tunnels in Teaching Basic Aerodynamics

Undergraduate programs that include one or more courses on basic aerodynamics, including those that are introductory to undergraduate engineering programs, can benefit from the use of low speed wind tunnels. At ERAU\u27s Prescott Campus two low speed wind tunnels have been used to give Aeronautical Science and beginning Aerospace Engineering students hands on experiences use of these tunnels in determining the lift curve slopes for various airfoils. The objectives of these lab experiences as listed in the course syllabus are: Objectives: The student is expected to familiarize him/herself with: Fundamental wind tunnel testing techniques. The use of an open return wind tunnel to measure the static pressure acting on an airfoil. The variation in the static pressure on the surface of an airfoil at various angles of attack. The use of surface tufts to assist in airflow visualization. Objectives: Using the data taken in the experiment, the student is also required to: Plot the pressure pattern on the top and bottom of an airfoil at four different angles of attack. Calculate the lift coefficients for each of these angles of attack. .Plot the coefficient of lift against the angle of attack measurements. This paper describes a specific experiment given to undergraduate aeronautical science students. In this lab all the learning objectives can be met by using small groups of students and providing them with detailed instructions. This is one of the most popular portions of the course on basic aerodynamics
