Domestic Violence Among Utah Women

Domestic violence is a serious and widespread issue affecting women and families in Utah. One in three Utah women will experience some form of domestic violence in her lifetime, and our rate is slightly higher than the national average (32.4% vs 28.8%). According to the Utah Domestic Violence Coalition, more than 40% of adult homicides in Utah since 2000 have been domestic violence related. Domestic violence is often presumed to refer only to physical violence, but it also includes many other forms of abuse— emotional, verbal, financial, spiritual, digital/online, and sexual. Domestic violence can be perpetrated against anyone regardless of age, race, ethnicity, religion, or socio-economic status. A recent survey shows that 86% of Utah women believe domestic violence is a problem in their communities, and 63% believe violence against women is in-creasing. It affects not only women but their families, friends, children, and communities

A Novel Technique for the Simultaneous Collection of Reflection and Transmission Data from Thin Films in the Extreme Ultraviolet

Studies of thin films in the Extreme Ultraviolet (EUV) are difficult given that most materials readily absorb photons of these energies. By depositing a thin film of the material of interest on a silicon photodiode, transmission measurements can be made throughout the EUV. If the measurements are made in a range of low absorption, the extinction coefficient, k, can be found with relative ease. However, if the material’s absorption is considerable, reflection measurements are needed to supplement the transmission data in order to find the optical constants n and k. The technique developed allows for reflection and transmission measurements to be taken simultaneously, which combined, account for all of the measurable photons from the original beam: (those which cannot be counted are photons absorbed into the thin film material). Also, the technique presented allows for data to be collected from practically all angles of incidence. This technique has been applied to a thin film of scandium oxide (d=65 nm), with measurements taken over wavelengths from 2.5-25 nm, and at angles of incidence 12 degrees from grazing to normal

Sexual Assault Among Utah Women

Nearly one in two women in the U.S. will experience some form of sexual violence victimization in her lifetime (broadly defined), and Utah has the same overall rate. According to the most recent Utah Commission on Criminal and Juvenile Justice report, when considering more specific definitions, one in three Utah women has been sexually assaulted, and one in six women report having been raped. In fact, according to the U.S. Department of Justice, rape occurs in Utah at a rate higher than the national average. Hence, sexual assault is a serious problem within the state

The Effects of Oxidation on the Refractive Index of Uranium Thin Films in the Extreme Ultraviolet

We measured the transmittance and reflectance of two samples in the extreme ultraviolet (XUV) at the Advanced Light Source at Lawrence Berkeley National Laboratory. The samples were prepared with approximately 20 nm of UOx with one reactively sputtered onto a diode, and one allowed to oxidize naturally on an identical diode. Fitting the reflectance data to the Parratt model yielded a more precise thickness of the UOx film. This thickness combined with a simple analysis of the transmission measurements provides estimates for the imaginary part of the index of refraction for UOx at approximately every tenth of a nanometer from about 3 nm to 30 nm with emphasis in the 12- to 13-nm range. Using these values, a first approximation for the real part of the refractive index has also been calculated. These values provide researchers with information for modeling, design, and fabrication of optical systems in the extreme ultraviolet

Production of intense, coherent, tunable narrow‐band lyman‐alpha radiation

Nearly transform limited pulses of 1216 Å radiation have been generated by sum frequency generation in 0.1 to 10 torr of mercury vapor. The summed input beams, consisting of photons at 3127 Å and 5454 Å originate in 1 MHz band‐width ring‐dye laser oscillators. The beams are amplified in pulsed‐dye amplifiers pumped by the frequency doubled output of a Nd:YAG laser. The 3127 Å photons are tuned to be resonant with the two‐photon 61S to 71S mercury transition. The VUV radiation can be tuned by varying the frequency of the third non‐resonant photon. We have also observed difference frequency generation at 2193 Å and intense fluorescence from the 61P state at 1849 Å. We have studied the intensity and linewidth dependence of the 1849 Å fluorescence and 1216 Å sum frequency signals on input beam intensity, mercury density, and buffer gas pressure and composition.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87716/2/49_1.pd
