Oyster Aquaculture Site Selection Using Landsat 8-Derived Sea Surface Temperature, Turbidity, and Chlorophyll a

Remote sensing data is useful for selection of aquaculture sites because it can provide water-quality products mapped over large regions at low cost to users. However, the spatial resolution of most ocean color satellites is too coarse to provide usable data within many estuaries. The Landsat 8 satellite, launched February 11, 2013, has both the spatial resolution and the necessary signal to noise ratio to provide temperature, as well as ocean color derived products along complex coastlines. The state of Maine (USA) has an abundance of estuarine indentations (∼3,500 miles of tidal shoreline within 220 miles of coast), and an expanding aquaculture industry, which makes it a prime case- study for using Landsat 8 data to provide products suitable for aquaculture site selection. We collected the Landsat 8 scenes over coastal Maine, flagged clouds, atmospherically corrected the top-of-the-atmosphere radiances, and derived time varying fields (repeat time of Landsat 8 is 16 days) of temperature (100 m resolution), turbidity (30 m resolution), and chlorophyll a (30 m resolution). We validated the remote-sensing-based products at several in situ locations along the Maine coast where monitoring buoys and programs are in place. Initial analysis of the validated fields revealed promising new areas for oyster aquaculture. The approach used is applicable to other coastal regions and the data collected to date show potential for other applications in marine coastal environments, including water quality monitoring and ecosystem management

Control estadístico para reducir los defectos de cierre en los envases de entero de anchoveta en salsa de tomate en la Corporación Pesquera ICEF S.A.C., CHIMBOTE- 2022

El presente proyecto de investigación tiene como objetivo implementar un control estadístico para reducir los defectos de cierre en el área de sellado en una empresa conservera de pescado. Se realizó una investigación aplicada con diseño de investigación pre experimental. La población fueron los envases de entero de anchoveta en salsa de tomate, contando con una muestra de 42 envases. Se utilizaron técnicas como la observación directa y el análisis documental. Los instrumentos empleados fueron: Formato de defectos, que ayudaron a identificar las variables críticas en el área de sellado; formato de muestreo, donde se registró los datos de las variables y atributos, que con ayuda de MINITAB 19 se dio a conocer el estado del proceso mediante las gráficas de control; registro de fallas de la máquina, donde se registró las fallas más reincidentes; y los formatos de porcentaje de defectos, que permitieron conocer los porcentajes de defecto de cierre. Mediante las gráficas de control C, P y XR, se determinó que existían causas asignables dentro del proceso que debían ser eliminadas, logrando así, estabilizar el proceso, además de mejorar el Cp de 0,69 0,74 0,59 a 1,14 1,09 1,21 y el Cpk de 0,36 0,58 0,52 a 0,95 1,05 1,7, además de reducir el porcentaje de defectos de cierre de un 28% a un 14,4%. Por ende, se concluye que, con el establecimiento del control estadístico, se logró reducir el porcentaje de defectos visuales y de medición en el sellado de los envases

Identification of sepsis in paediatric emergency departments: A scoping review

Aim: Sepsis is an acute illness associated with significant morbidity and mortality. Early detection and time‐sensitive management of sepsis has been shown to improve outcomes. We report the results of a scoping review to explore methods evaluated for the identification of sepsis in children presenting to emergency departments. Methods: A systematic literature search was carried out on two databases, Medline and Web of Science, to identify relevant studies published from 1990 to 2022. Data were extracted for age groups including study design, reference standard used for comparison, sepsis identification method evaluated and study quality. Results: A total of 89 studies were identified from the literature search. There was significant heterogeneity in the age groups including study design and reference standards used for evaluating the performance of the sepsis identification methods. There has been a substantial increase in the number of published studies in the last 2 years. Conclusion: Our scoping review identifies marked heterogeneity in approaches to identifying sepsis but demonstrates a recent focus of research on patient outcomes. Using appropriate core outcome sets, developing reference standards, monitoring sepsis prevalence via registries and continuously monitoring process measures will provide robust evidence to identify the best performing identification tools and the impact they have on patient‐orientated outcomes

Bone marrow mesenchymal stem cells as nuclear donors improve viability and health of cloned horses

Introduction: Cell plasticity is crucial in cloning to allow an efficient nuclear reprogramming and healthy offspring. Hence, cells with high plasticity, such as multipotent mesenchymal stem cells (MSCs), may be a promising alternative for horse cloning. In this study, we evaluated the use of bone marrow-MSCs (BM-MSCs) as nuclear donors in horse cloning, and we compared the in vitro and in vivo embryo development with respect to fibroblasts. Materials and methods: Zona-free nuclear transfer was performed using BM-MSCs (MSC group, n=3432) or adult fibroblasts (AF group, n=4527). Embryos produced by artificial insemination (AI) recovered by uterine flushing and transferred to recipient mares were used as controls (AI group). Results: Blastocyst development was higher in the MSC group than in the AF group (18.1% vs 10.9%, respectively; p<0.05). However, pregnancy rates and delivery rates were similar in both cloning groups, although they were lower than in the AI group (pregnancy rates: 17.7% [41/232] for MSC, 12.5% [37/297] for AF and 80.7% [71/88] for AI; delivery rates: 56.8% [21/37], 41.5% [17/41] and 90.1% [64/71], respectively). Remarkably, the gestation length of the AF group was significantly longer than the control (361.7}10.9 vs 333.9}8.7 days), in contrast to the MSC group (340.6}8.89 days). Of the total deliveries, 95.2% (20/21) of the MSC-foals were viable, compared to 52.9% (9/17) of the AF-foals (p<0.05). In addition, the AF-foals had more physiological abnormalities at birth than the MSC-foals; 90.5% (19/21) of the MSC-delivered foals were completely normal and healthy, compared to 35.3% (6/17) in the AF group. The abnormalities included flexural or angular limb deformities, umbilical cord enlargement, placental alterations and signs of syndrome of neonatal maladjustment, which were treated in most cases. Conclusion: In summary, we obtained 29 viable cloned foals and found that MSCs are suitable donor cells in horse cloning. Even more, these cells could be more efficiently reprogrammed compared to fibroblasts.Fil: Olivera, R.. Kheiron Sa.; ArgentinaFil: Moro, Lucía Natalia.

“Be a Pattern for the World”: The Development of a Dark Patterns Detection Tool to Prevent Online User Loss

Dark Patterns are designed to trick users into sharing more information or spending more money than they had intended to do, by configuring online interactions to confuse or add pressure to the users. They are highly varied in their form, and are therefore difficult to classify and detect. Therefore, this research is designed to develop a framework for the automated detection of potential instances of web-based dark patterns, and from there to develop a software tool that will provide a highly useful defensive tool that helps detect and highlight these patterns

Isokinetic strength qualities that differentiate rapid deceleration performance in male youth academy soccer players

Introduction Decelerating (DEC) is just as frequent as accelerating in contemporary soccer match play (Russell et al., 2014). Recent evidence suggests that lower body eccentric strength directly improves the ability of a player to produce and tolerate braking forces (Spiteri et al., 2014). The aim of the present study was to identify if measures of isokinetic strength can differentiate performance of a rapid DEC maneuver. Method Nineteen (n=19) academy youth soccer players (age: 16.7 + 1yrs; height: 175 + 8.4cm ; body mass: 69.1+ 7.5kg; body fat: 9.5 + 3.9%) participated in the study. Tests included: isokinetic dynamometer (Cybex ΙΙ, Cybex International Inc., New York, USA) strength profiling of quadricep (Q) and hamstring (H) peak concentric (con) and eccentric (ecc) torque (both dominant [kicking leg] and non-dominant legs) assessed at slow (60°/s) and fast (180°/s) angular velocities. Functional H:Q ratios representative of knee flexion (Hcon:Qecc) and extension (Hecc:Qcon) was also calculated; 30m linear sprint time (with 5m, 10m and 20m splits) was recorded using a single beam timing system (Witty, Microgate, Italy) and rapid DEC quantified using time to stop (TTS) and distance to stop (DTS) determined following a 20m maximal acceleration (within 5% threshold of best 20m linear sprint time) using video analysis (Dartfish ProSuite 2011, Fribourg, Switzerland) captured from a 50Hz video camera (Panasonic HDC-HS900, Japan). Results 10, 20 and 30m sprint times had significantly large correlations with fast con peak Q torque (dom, r=-0.624, -0.568, - 0.621 and non-dom, r=-0.513, -0.512, -0.509) with fast peak H torque comprising significant correlations in the dom leg (r= -0.773, -0.561, -0.761) with moderate to large correlations in the non-dom leg (r= -0.5, -0.468, -0.464). At slow velocity con peak H torque had moderate to large correlations with 10, 20 and 30m sprint times. No significant correlations were found for peak con strength in either Q or H for DEC performance (TTS and DTS). Slow velocity Ecc peak Q torque (dom, r= -0.503, nondom, r=-0.542) and time to peak torque (r=-0.465) was significantly correlated to DEC TTS. No significant correlations were found for fast ecc strength parameters in Q or H for either sprint or DEC performance. Sprint and DEC performance had no significant correlations. Discussion The present study illustrates the need for specific strength qualities for attainment of high running velocities and rapid DEC performance. Specifically, players with superior sprint speed can produce high peak con forces in both Q and H at fast velocities. DEC seems to be a unique movement skill requiring specific ecc strength qualities. Interestingly, in this study slow velocity ecc strength of the Q seems to be critical for production of braking forces and reducing the time spent DEC. Increased time spent DEC has been found to increase tissue damage and muscle soreness, subsequently affecting post match recovery kinetics (Young et al., 2012). In conclusion this study highlights the need for careful consideration to developing strength qualities needed for DEC alongside those more commonly known for sprinting and accelerating.
