Bolstering Mission Success: Lessons Learned for Small Satellite Developers Adhering to Manned Spaceflight Requirements

This paper is meant to impart critical knowledge to new and upcoming spacecraft developers (universities, high schools, research centers, young commercial companies, etc.) regarding lessons learned that they can implement to create successful spacecraft missions. This perspective comes from NanoRacks, a “space access provider”, where we’ve gained enormous expertise on how to design and build to requirements driven by human-rated spaceflight. As we all know, operating in space is only half of the battle

From Jongleur to Minstrel: The Professionalization of Secular Musicians in Thirteenth- and Fourteenth-Century Paris

This paper discusses the circumstances surrounding the formation of a Parisian guild for minstrels, the Corporation des ménétriers, in 1321. This action marks a pivotal moment in the history of urban minstrelsy and stands in stark contrast to the works of theologians who insisted that jongleurs had no practical use to society. In order to understand how this guild came to be, I first examine how the evolving intellectual climate in Paris provided a path for jongleurs to professionalize. I then explore the geography and demographics of medieval Paris, using the tax records levied by Philip the Fair, and the charter and early guild records of the Corporation des ménétriers. These documents suggest that minstrels had already become a stable presence on the Rue aus Jugléeurs well before their formal incorporation in 1321. Furthermore, by 1335, the guild had funded and constructed both a hospital and a chapel, evidently with the aim of benefiting not only guild members, but also their local community. This type of institutional construction was common among many other guilds, and I argue that by emulating those practices, Parisian minstrels were able to demonstrate that their labor was skilled indeed, and that their craft produced a tangible benefit to society.

Advancing Pharmacist Collaborative Care within Academic Health Systems.

INTRODUCTION:The scope of pharmacy practice has evolved over the last few decades to focus on the optimization of medication therapy. Despite this positive impact, the lack of reimbursement remains a significant barrier to the implementation of innovative pharmacist practice models. SUMMARY:We describe the successful development, implementation and outcomes of three types of pharmacist collaborative care models: (1) a pharmacist with physician oversight, (2) pharmacist-interprofessional teams and (3) physician-pharmacist teams. The outcome measurement of these pharmacist care models varied from the design phase to patient volume measurement and to comprehensive quality dashboards. All of these practice models have been successfully funded by affiliated health systems or grants. CONCLUSIONS:The expansion of pharmacist services delivered by clinical faculty has several benefits to affiliated health systems: (1) significant improvements in patient care quality, (2) access to experts in specialty areas, and (3) the dissemination of outcomes with national and international recognition, increasing the visibility of the health system

Player responses to match and training demands during an intensified fixture schedule in professional rugby league: A case study.

As accepted for publicationPlayer loads and fatigue responses are reported in 15 professional rugby league players (24.3 ± 3.8 y) during a period of intensified fixtures. Repeated measures of internal and external loads, perceived well-being, and jump flight time were recorded across 22 d, comprising 9 training sessions and matches on days 5, 12, 15, and 21 (player exposure: 3.6 ± 0.6 matches). Mean training loads (session rating of perceived exertion × duration) between matches were 1177, 1083, 103, and 650 AU. Relative distance in match 1 (82 m/min) and match 4 (79 m/min) was very likely lower in match 2 (76 m/min) and likely higher in match 3 (86 m/min). High-intensity running (≥5.5 m/s) was likely to very likely lower than match 1 (5 m/min) in matches 2–4 (2, 4, and 3 m/min, respectively). Low-intensity activity was likely to very likely lower than match 1 (78 m/min) in match 2 (74 m/min) and match 4 (73 m/min) but likely higher in match 3 (81 m/min). Accumulated accelerometer loads for matches 1–4 were 384, 473, 373, and 391 AU, respectively. Perceived well-being returned to baseline values (~21 AU) before all matches but was very likely to most likely lower the day after each match (~17 AU). Prematch jump flight times were likely to most likely lower across the period, with mean values of 0.66, 0.65, 0.62, and 0.64 s before matches 1–4, respectively. Across a 22-d cycle with fixture congestion, professional rugby league players experience cumulative neuromuscular fatigue and impaired match running performance

Comparison of echocardiographic methods for calculating left ventricular mass in elite rugby football league athletes and the impact on chamber geometry

Background: Recommendations for the echocardiographic assessment of left ventricular (LV) mass in the athlete suggest the use of the linear method using a two-tiered classification system (2TC). The aims of this study were to compare the linear method and the area-length (A-L) method for LV mass in elite rugby football league (RFL) athletes and to establish how any differences impact the classification of LV geometry using 2TC and four-tier (4TC) classification systems. Methods: Two hundred and twenty (220) male RFL athletes aged 25 ± 5 (14–34 years) were recruited. All athletes underwent echocardiography and LV mass was calculated by the American Society of Echocardiography (ASE) corrected Linear equation (2D) and the A-L method. Left ventricular mass Index (LVMi) was used with relative wall thickness to determine geometry in the 2TC and with concentricity and LV end diastolic volume index for the 4TC. Method specific recommended cut-offs were utilised. Results: Higher values of absolute (197 ± 34 vs. 181 ± 34 g; p < 0.0001) and indexed (92 ± 13 vs. 85 ± 13 g/m2; p < 0.0001) measures of LV mass were obtained from A-L compared to the linear method. Normal LV geometry was demonstrated in 98.2% and 80% of athletes whilst eccentric hypertrophy in 1.4% and 19.5% for linear and A-L respectively. Both methods provided 0.5% as having concentric remodelling and 0% as having concentric hypertrophy. Allocation to the 4TC resulted in 97% and 80% with normal geometry, 0% and 8.6% with eccentric dilated hypertrophy, 0% and 7.7% with eccentric non-dilated hypertrophy, 1.4% and 0.5% with concentric remodelling and 1.4% and 3% with concentric non-dilated hypertrophy for linear and A-L methods respectively. No participants had concentric dilated hypertrophy from either methods. Conclusion: The linear and A-L method for calculation of LV mass in RFL athletes are not interchangeable with significantly higher values obtained using A-L method impacting on geometry classification. More athletes present with eccentric hypertrophy using 2TC and eccentric dilated/non-dilated using 4TC. Further studies should be aimed at establishing the association of A-L methods of LV mass and application of the 4TC to the multi-factorial demographics of the athlete

Single-center task analysis and user-centered assessment of physical space impacts on emergency Cesarean delivery

Cesarean delivery is the most common surgery performed in the United States, accounting for approximately 32% of all births. Emergency Cesarean deliveries are performed in the event of critical maternal or fetal distress and require effective collaboration and coordination of care by a multidisciplinary team with a high level of technical expertise. It is not well understood how the physical environment of the operating room (OR) impacts performance and how specialties work together in the space. Objective This study aimed to begin to address this gap using validated techniques in human factors to perform a participatory user-centered analysis of physical space during emergency Cesarean. Methods This study employed a mixed-methods design. Focus group interviews and surveys were administered to a convenience sample (n = 34) of multidisciplinary obstetric teams. Data collected from focus group interviews were used to perform a task and equipment analysis. Survey data were coded and mapped by specialty to identify reported areas of congestion and time spent, and to identify themes related to physical space of the OR and labor and delivery unit. Results Task analysis revealed complex interdependencies between specialties. Thirty task groupings requiring over 20 pieces of equipment were identified. Perceived areas of congestion and areas of time spent in the OR varied by clinical specialty. The following categories emerged as main challenges encountered during an emergency Cesarean: 1) size of physical space and equipment, 2) layout and orientation, and 3) patient transport. Conclusion User insights on physical space and workflow processes during emergency Cesarean section at the institution studied revealed challenges related to getting the patients into the OR expediently and having space to perform tasks without crowding or staff injury. By utilizing human factors techniques, other institutions may build upon our findings to improve safety during emergency situations on labor and delivery

Are there benefits from the use of fish oil supplements in athletes? A systematic review

Despite almost 25 years of fish oil supplementation (FS) research in athletes and widespread use by the athletic community, no systematic reviews of FS in athletes have been conducted. The objectives of the systematic review are to: 1) provide a summary of the effect of FS on the athlete’s physiology, health and performance; 2) report on the quality of the evidence; 3) document any side effects as reported in the athlete research; 4) discuss any risks associated with FS use; 5) provide guidance for FS use and highlight gaps for future research. Electronic databases (PubMed, EMBASE, Web of Science, Google Scholar) were searched up until April 2019. Only randomised placebo-controlled trials (RCTs) in athletes, assessing the effect of FS on a health, physiological/biochemical, or performance variable were included. Of the 137 papers identified through searches, 32 met inclusion criteria for final analysis. Athletes varied in classification from recreational to elite, and from Olympic to professional sports. Mean age for participants was 24.9 4.5 years, with 70% of RCTs in males. We report consistent effects for FS on reaction time, mood, cardiovascular dynamics in cyclists, skeletal muscle recovery, the pro-inflammatory cytokine TNF-alpha, and post-exercise nitric oxide responses. No clear effects on endurance performance, lung function, muscle force or training adaptation were evident. Methodological quality, applying the PEDro scale, ranged from 6 to a maximum of 11, with only four RCTs reporting effect sizes. Few negative outcomes were reported. We report various effects for FS on the athlete’s physiology; the most consistent findings were on the central nervous system, cardiovascular system, pro-inflammatory cytokines, and skeletal muscle. We provide recommendations for future research and discuss the potential risks with FS use
