Cretaceous and Eocene U-Pb Zircon Migmatite Ages from the East Humboldt Range Metamorphic Core Complex, Nevada

Zircon separates from migmatite samples from the East Humboldt Range (EHR), northern Nevada were U-Pb dated using secondary ionization mass spectrometry. Cathodoluminescence images of zircons show bright anhedral cores with abundant euhedral overgrowths surrounding them. The overgrowths give U-Pb dates indicating two periods of zircon growth. Inner rims have a Cretaceous age population at 70.6 ± 2.6 Ma. Outer rims give Eocene ages that either fall in to a single-age population at 45 ± 1.3 Ma or are part of a range from 41-31 Ma. Discordant zircon cores have upper intercepts between 1.8 -1.0 Ga. Cretaceous and Eocene ages are interpreted as recording protracted growth of anatectic zircon during Mesozoic thrust burial and Cenozoic regional extension. McGrew et al. (2000) reported a U-Pb TIMS age of 84.8 ± 2.8 Ma on zircons from the EHR, while Premo et al. (2008) reported ion probe ages of 90-71 Ma from zircons in the same area

The After-Visit Summary: An Opportunity for Technical Communicators

The After-Visit Summary (AVS) is a document patients receive while being discharged from a medical appointment. In this paper, I explore the aspects of patient education materials (PEMs), health literacy, and plain language in respect to the AVS with research from the fields of technical communication, health communication, and medicine. The narrative included depicts my own personal experience with the document to emphasize my push for action. The main objective for this paper is to urge technical communication scholars to analyze the AVS and evaluate it for areas of improvement. A benefit to both patients and practitioners, optimizing the AVS could contribute to more effective at-home care

The Physiological and Psychological Benefits of CrossFit Training – A Pilot Study

CrossFit has been one of the fastest growing training methods in the fitness industry since its inception in 2000. CrossFit combines classic strength and conditioning along with gymnastics movements, Olympic weightlifting, and other functional movements into a constantly varied, high intensity workout. The success of CrossFit and what seems to be exponential growth of their over 10,000 affiliated gyms is undeniable. This popularity might be stem from two main factors: the physiological changes of training and the psychological benefits of a community emphasized, social atmosphere. However, there is very limited research evidence supporting the potential benefits of CrossFit . This study was conducted to investigate the physiological and psychological benefits of CrossFit training in a healthy adult population undergoing their first exposure to the training method. Sixteen participants were recruited from a local CrossFit affiliate in San Angelo, Texas. Participants completed a series of self-report psychological questionnaires including the Motives for Physical Activity Measures (MPAM), Mental Health Inventory 38 (MHI-38), and the Group Environment Questionnaire (GEQ). Following these questionnaires, physical metrics including: heart rate, blood pressure, height, body weight, body composition via Dual-energy X-ray Absorptiometry (DXA), along with performance measures including 1-RM back squat, 1-RM bench press, vertical jump test, and a Wingate Anaerobic Power Test were conducted. The CrossFit program was conducted for 8 weeks by certified CrossFit coaches at the local affiliate gym. After the 8-week training, the participants were reassessed using the same measures. Over the course of the study, 6 participants completed the program (2 males, 4 females, 36.2 ± 10.8 years of age, 73.6 ± 7.4 kg, 167.6 ± 5.5 cm, and 31.0 ± 9.2% body fat). Despite the large attrition rate, there were statistically significant increase of lean mass (1.44 ± 1.26 kg; p= 0.039), decrease of mean fat (1.67 ± 1.17 kg ; p= 0.017) and changes in interest subset of motivation from MPAM motivational test (p \u3c 0.05). In conclusion, this pilot study suggests that CrossFit training might be beneficial for improving body composition and concurrently changes certain motivational factors to continue engaging in the fitness activity. Further studies with a longer intervention period and a larger sample size are needed to support these findings

It's in the Syllabus: National Narratives and Curricular Politics in Postcolonial Education

Reviewing and reiterating the claim that curriculum content is inherently political and never neutral, this thesis explores the legacies of British colonization on Jamaican education by looking at education reforms and curriculum evolution to track the presence of culturally relevant classroom material in the Anglophone Caribbean. Both England and Jamaica have utilized education for re-constructing national identity and priorities as they negotiate historical narratives and canonized curriculum material when presented with the forces and processes of globalization. Syllabi from five secondary schools in Kingston, Jamaica are used for a case study. While the curriculum content in Jamaican secondary schools is now inclusive and culturally relevant, the education structure itself is a colonial vestige, in terms of the excessive standardized testing that tracks students into each grade level. While the canonization of previously excluded Caribbean authors into the curriculum by the Caribbean Examinations Council has effectively introduced culturally relevant course material, additional recommendations include cultivating a meta-curriculum, whereby teachers and students engage in classroom discussion about why and how the required curriculum material was selected, in order to better understand the political nature of curriculum choice and the ramifications it can have in terms of indoctrinating ideas about nationality, historical narratives, and identity

Wins Above Replacement Career Trajectory Curves

The purpose of this research is to explore the possibility of being able to model a Major League Baseball (MLB) players Wins Above Replacement (WAR) over the course of his career and use it to predict the success of other players who are similar in the early years of their respective careers. This would be a valuable tool that could be used to more capably predict how certain young players will develop. The reason that we have chosen WAR as our statistic of interest is because it is an all-encompassing statistic that attempts to explain how many wins an individual player contributes to their team over the number of wins a player of replacement level would contribute (a replacement level player being the equivalent of a AAA player that is readily available). In order to approach developing this model, we first have to compute WAR using 80 years of play-by-play data by calculating how many runs a player contributes on a Plate Appearance (PA) by plate appearance basis. Instead of using WAR per season, we have decided to use WAR per 100 At-Bats (AB) in order to have more points in our model and to create a more accurate career WAR trajectory curve. Through this research, we hope to be able to use the model that we create to predict the career trajectory of developing players.Ope

UAV Catapult

This document outlines the Senior Design Project proposed by Dr. Aaron Drake that was assigned to a team of Mechanical Engineering students at California Polytechnic State University, San Luis Obispo. The purpose of this project was to design, build, test, and finalize a launching system for two small, fixed wing, unmanned aerial vehicles (UAVs) owned by Dr. Drake and Cal Poly. The goal was to create a system that was both portable and reliable to use, only requiring a two-person team to use effectively in the field. The most important design requirements were determined to be the launch speed, assembly time, and storage size. Multiple propulsion methods were explored, with a pneumatic piston cylinder chosen for the preliminary design. A side clamping carriage design was selected due to the shape of the UAVs being launched. A structural prototype of the UAV carriage was constructed, and the final design was developed as a result of data obtained from the prototype. Following the creation of our final design, a manufacturing plan and design verification plan were produced to bring the concept to fruition. With these plans in place, parts were ordered, and construction began. This document will describe the background research done, the objectives of the project, the preliminary and final design, the manufacturing and testing process, difficulties and obstacles faced, our final results, and what can be improved upon in the future

Forecasting neuromuscular recovery after anterior cruciate ligament injury: Athlete recovery profiles with generalized additive modeling

A retrospective analysis of longitudinally collected athlete monitoring data wasconducted to generate a model of neuromuscular recovery after anterior cruciateligament (ACL) injury and reconstruction (ACLR). Neuromuscular testing data in-cluding countermovement jump (CMJ) force‐time asymmetries and knee extensorstrength (maximum voluntary contractionext) asymmetries (between‐limb asymmetryindex—AI) were obtained from athletes with ACLR using semitendinosus (ST) au-tograft (n= 29; AI measurements: n= 494), bone patellar tendon bone autograft(n= 5; AI measurements:n= 88) and noninjured controls (n= 178; AI measurements:n= 3188). Explosive strength measured as the rate of torque development was alsocalculated. CMJ force‐time asymmetries were measured over discrete movementphases (eccentric deceleration phase, concentric phase). Separate additive mixedeffects models (additive mixed effects model [AMM]) were fit for each AI with amain effect for the surgical technique and a smooth term for the time since surgery(days). The models explained between 43% and 91% of the deviance in neuro-muscular recovery after ACLR. The mean time course was generated from the AMM.Comparative neuromuscular recovery profiles of an athlete with an acceleratedprogression and an athlete with a delayed progression after a serious multiligamentinjury were generated. Clinical Significance: This paper provides a new perspectiveon the utility of longitudinal athlete monitoring including routine testing to developmodels of neuromuscular recovery after ACLR that can be used to characterizeindividual progression throughout rehabilitation

Multiplex giant magnetoresistive biosensor microarrays identify interferon-associated autoantibodies in systemic lupus erythematosus.

High titer, class-switched autoantibodies are a hallmark of systemic lupus erythematosus (SLE). Dysregulation of the interferon (IFN) pathway is observed in individuals with active SLE, although the association of specific autoantibodies with chemokine score, a combined measurement of three IFN-regulated chemokines, is not known. To identify autoantibodies associated with chemokine score, we developed giant magnetoresistive (GMR) biosensor microarrays, which allow the parallel measurement of multiple serum antibodies to autoantigens and peptides. We used the microarrays to analyze serum samples from SLE patients and found individuals with high chemokine scores had significantly greater reactivity to 13 autoantigens than individuals with low chemokine scores. Our findings demonstrate that multiple autoantibodies, including antibodies to U1-70K and modified histone H2B tails, are associated with IFN dysregulation in SLE. Further, they show the microarrays are capable of identifying autoantibodies associated with relevant clinical manifestations of SLE, with potential for use as biomarkers in clinical practice
