A Dynamical Study of the Non-Star Forming Translucent Molecular Cloud MBM16: Evidence for Shear Driven Turbulence in the Interstellar Medium

We present the results of a velocity correlation study of the high latitude cloud MBM16 using a fully sampled $^{12}$CO map, supplemented by new $^{13}$CO data. We find a correlation length of 0.4 pc. This is similar in size to the formaldehyde clumps described in our previous study. We associate this correlated motion with coherent structures within the turbulent flow. Such structures are generated by free shear flows. Their presence in this non-star forming cloud indicates that kinetic energy is being supplied to the internal turbulence by an external shear flow. Such large scale driving over long times is a possible solution to the dissipation problem for molecular cloud turbulence.Comment: Uses AAS aasms4.sty macros. Accepted for publication in Ap

A comparision of saccadic eye movements by keyboard musicians when reading music versus text

Many studies have been done on saccadic eye movements while reading text, but none have been done to see how reading music differs from reading text. The saccade is one of the major components of eye movements that has been observed in previous studies, and the EYE TRAC has been used to obtain a quantitative measurement of the number of saccades while reading. The intent of this study was to determine the difference in the number of saccadic eye movements between reading music and reading text, thereby indirectly measuring the difference in visual demand between these two tasks. We used the Eye Trac to measure the number of saccades made by keyboard musicians first while reading the standard Eye Trac text, and secondly by reading musical notes which have been reproduced to simulate the standard text as closely as possible. Both graphical and statistical analyses were performed on the data obtained during testing, and both dramatically show the difference in visual demand. The mean number of saccades per second was significantly higher for reading music (5.032) as compared to reading text (3.529), and the overall time required to complete each task also was very different (16.4 seconds for text, 120 seconds for music). Statistical analysis predicted that the probability that the data occurred by chance was .0001

Community Health: A Patient Satisfaction Inquiry at Puentes de Salud, a Health and Wellness Clinic Centering the Latinx Community in Philadelphia, PA

Free healthcare clinic models contribute the health and wellness of a community providing essential preventative and acute healthcare screening and diagnosis, mitigating negative health outcomes and higher healthcare costs for the individual. Current research supports optimizing community health through knowledge gained from frequent assessment of patient satisfaction and perceived barriers to healthcare. This study examined the level of patient satisfaction at Puentes de Salud (Puentes), a nonprofit healthcare clinic serving Philadelphia’s Latinx migrant community. Utilizing a validated and reliable survey instrument that captures patient satisfaction with healthcare, Spanish or English- speaking patients (n= 79) 18-89 years of age completed a self-administered survey. In addition, a demographic questionnaire with open ended clinic inquiry questions was developed to assesses healthcare access barriers. Participants reported a higher level of satisfaction with higher number of clinic visits but did not report higher scores with more years associated with the clinic. Appointment reminders, improving communication/ answering phone calls, and access to specialty services were suggested to optimize participant health. Improving patient satisfaction and identifying perceived barriers to healthcare presents a unique opportunity to incorporate community needs at Puentes to ensure future growth and utilization of the clinic

Cyclotron Produced Radionuclides for Diagnosis and Therapy of Human Neoplasms

This project funded since 1986 serves as a core project for cancer research throughout MSKCC, producing key radiotracers as well as basic knowledge about thel physics of radiation decay and imaging, for nuclear medicine applications to cancer diagnosis and therapy. In recent years this research application has broadened to include experiments intended to lead to an improved understanding of cancer biology and into the discovery and testing of new cancer drugs. Advances in immune based radiotargeting form the basis for this project. Both antibody and cellular based immune targeting methods have been explored. The multi-step targeting methodologies (MST) developed by NeoRex (Seattle,Washington), have been adapted for use with positron emitting isotopes and PET allowing the quantification and optimization of targeted delivery. In addition, novel methods for radiolabeling immune T-cells with PET tracers have advanced our ability to track these cells of prolonged period of time

Relationship of surface changes to metal leaching from tungsten composite shot exposed to three different soil types

Physical changes that occur on the surface of fired shots due to firing and impact with soil may increase the dissolution of muniton metals. Increased metal dissolution could potentially increase metal transport and leaching, affecting metal concentrations in surface and groundwater. This research describes the relationship between the surface changes on fired tungsten–nickel–iron (94% W:2% Ni:4% Fe) composite shots and metals leaching from those shots. Tungsten composite shot was fired into, and aged in, three soil types (Silty Sand, Sandy Clay, and Silt) in mesoscale rainfall lysimeters to simulate live-fire conditions and subsequent interactions between the metals of the composite and soil. Leachate, runoff, and soil samples were collected from the lysimeters and analyzed for metal content. The shots were analyzed using scanning electron microscopy (SEM) to evaluate surface changes. SEM results indicated that a soil’s particle size distribution initially affected the amount of metal that was sheared from the surface of the fired W-composite shots. Shearing was greatest in soils with larger soil particles (sand and gravel); shearing was least in soils composed of small soil particles (fines). Increased metallic shearing from the shot’s surface was associated with increasedWdissolution, compared to controls, following a simulated 1 year soil aging
