Soybeans at the Dinner Table

Soybeans once came to the dinner table only as a sprout in a specialty dish. But today, the soybean is there in many forms. The key to this new acceptance is protein

Tracing colliding winds in the UV line orbital variability of gamma-ray binaries

Gamma-ray binaries emit most of their radiated power beyond ~10 MeV. The non-thermal emission is thought to arise from the interaction of the relativistic wind of a rotation-powered pulsar with the stellar wind of its massive (O or Be) companion star. A powerful pulsar creates an extended cavity, filled with relativistic electrons, in the radiatively-driven wind of the massive star. As a result, the observed P Cyg profiles of UV resonant lines from the stellar wind should be different from those of single massive stars. We propose to use UV emission lines to detect and constrain the colliding wind region in gamma-ray binaries. We compute the expected orbital variability of P Cyg profiles depending upon the interaction geometry (set by the ratio of momentum fluxes from the winds) and the line-of-sight to the system. We predict little or no variability for the case of LS 5039 and PSR B1259-63, in agreement with currently available HST observations of LS 5039. However, variability between superior and inferior conjunction is expected in the case of LS I+61 303.Comment: Accepted for publication in MNRA

What We Learned About Nutrition From the War

It took a war to teach us how to eat—a war in which food was as vital as bombs for victory. In feeding our families today we should not forget what we learned then

Five Culprits of Food Poisoning

Some of the names of these culprits are real tongue-twisters- some of the others are more commonly known. This article isn\u27t designed to scare you away from the dinner or picnic isn\u27t designed to scare you away from the dinner or picnic table. But forearmed with some knowlwedge about these microorganisms, you can respect them, and they\u27ll cause you no more harm than the twisted tongue when you say them

A Mechanism-Based Approach to the Identification of Age–Period–Cohort Models

This article offers a new approach to the identification of age-period-cohort (APC) models that builds on Pearl's work on nonparametric causal models, in particular his front-door criterion for the identification of causal effects. The goal is to specify the mechanisms through which the age, period, and cohort variables affect the outcome and in doing so identify the model. This approach allows for a broader set of identification strategies than has typically been considered in the literature and, in many circumstances, goodness of fit tests are possible. The authors illustrate the utility of the approach by developing an APC model for political alienation.Sociolog

Risk Behaviors and Self-Reported Illnesses Among Pacific Northwest Surfers

Although surfers have high incidental exposure to marine waters, no studies have investigated if surfer risk behaviors (such as surfing during advisories, near an outfall, during a rain event, or use of personal protective equipment) increase or decrease the risk of acquiring waterborne illnesses. We used a web-based survey to assess the association between risk-based behaviors with self-reported illnesses among Pacific Northwest surfers. Commonly reported illnesses include: ear infection or discharge (38%), sore throat or a cough (28%), diarrhea (16%), fever (10.5%) and vomiting (7%). Surfing often during rain events was associated with an increased likelihood of diarrhea (OR=2.7; 95% Cl: 1.4-5.47), sore throat (OR=1.26; 95% Cl:1.01-2.05), and ear infection (OR=1.39; 95% Cl: 1.01-2.32). Surfing during a health advisory was associated with increased likelihood of diarrhea (OR = 1.94; 95% CI: 1.03-4.64) and sore throat (OR = 2.32; 95% CI: 1.23-4.40). Other behaviors associated with increased illnesses include body surfing, surfing near an outfall, frequency of surfing and use of ear plugs. Approximately 40% of surfers were unaware if they had surfed during an active health advisory and 29% knowingly surfed during advisories, suggesting the need to engage this population about potential harm and behaviors that may increase health risk.©IWA Publishing 2015.
