Water Quality Monitoring

This activity is designed to study the water quality of a stream in your area, by measuring the temperature, pH, alkalinity, conductivity and total dissolved solids. It lends itself to integrating biology with earth science when using the microscope to study the living organisms in the water. The main objective is to determine the water quality of a local fresh water stream, as surface waters may be adversely impacted by human activity. This site has detailed instructions for conducting the listed tests. Educational levels: High school, Middle school

The Battery K, 1st Ohio Light Artillery Monument

At the corner of Carlisle and Lincoln Streets there is an original 12-pounder Napoleon that stands guard over a granite monument. The monument is just one of the monuments to numerous artillery batteries that fought at the battle of Gettysburg. So what makes this monument so unique that warrants a paper written on it? According to the monument this battery, “engaged the enemy with great gallantry.” Thus their deeds at Gettysburg should not go unnoticed. Also the monument lies on the campus of Gettysburg College, and many college students are unaware of the events that went on upon this campus on the day of July1-3, 1863. This monument is not just some small monuments that you see on the battlefield; this is a large and impressive monument. But what about this monument, a monument to Battery K of the 1st Ohio Light Artillery, what is their story, and how did they get to be on a spot in the northern corner of our campus. Why did these men from Ohio end up all the way in Gettysburg, Pennsylvania? The story of Battery K at Gettysburg is a story that is very intense one although the regiment only fought here for half an hour.

Pulsar motions from neutrino oscillations induced by a violation of the equivalence principle

We analize a possible explanation of the pulsar motions in terms of resonant neutrino transitions induced by a violation of the equivalence principle (VEP). Our approach, based on a parametrized post-Newtonian (PPN) expansion, shows that VEP effects give rise to highly directional contributions to the neutrino oscillation length. These terms induce anisotropies in the linear and angular momentum of the emitted neutrinos, which can account for both the observed translational and rotational pulsar motions. The violation needed to produce the actual motions is completely compatible with the existing bounds.Comment: 6 pages, no figure

xFx_F Dependence of Drell-Yan Transverse Moemtum Broadening

We analyze $x_F$ dependence of Drell-Yan transverse momentum broadening in hadron-nucleus collisions. In terms of generalized factorization theorem, we show that the $x_F$ dependence of transverse momentum broadening, $\Delta < q_T^2 > (x_F)$, can be calculated in perturbative QCD. We demonstrate that $\Delta (x_F)$ is a good observable for studying the effects of initial-state multiple scattering and extracting quark-gluon correlation functions.Comment: 10 pages, 3 figure

Nuclear dependence asymmetries in direct photon production

We study the nuclear dependences of high-$p_T$ jet cross sections in one photon and one jet production in proton-nucleus collisions. We find that there exist asymmetries between the outgoing jets and photons. A convincing reason responsible for those asymmetries are demonstrated in perturbative QCD. Significant nuclear enhancements are also found in the inclusive jet cross sections.Comment: 9 pages, LaTeX, 5 ps-figure
