Can measurements of foraging behaviour predict variation in weight gains of free-ranging cattle?

Context. Technologies are now available to continuously monitor livestock foraging behaviours, but it remains unclear whether such measurements can meaningfully inform livestock grazing management decisions. Empirical studies in extensive rangelands are needed to quantify relationships between short-term foraging behaviours (e.g. minutes to days) and longer-term measures of animal performance. Aims. The objective of this study was to examine whether four different ways of measuring daily foraging behaviour (grazing-bout duration, grazing time per day, velocity while grazing, and turn angle while grazing) were related to weight gain by free-ranging yearling steers grazing semiarid rangeland. Methods. Yearling steers were fitted with neck collars supporting a solar-powered device that measured GPS locations at 5 min intervals and used an accelerometer to predict grazing activity at 4 s intervals. These devices were used to monitor steers in four different paddocks that varied in forage biomass, and across two grazing seasons encompassing a wide range of forage conditions. Steer weight gain (kg/steer.day) was measured in each paddock during each of three ~60 day time intervals, and daily foraging behaviours were measured during 15–21 days in each interval. Results. A model based on only two daily measurements of foraging behaviour, mean grazing bout duration (calculated at a 5 min resolution) and mean velocity while grazing explained 62% of the variation in animal weight gain. Conclusions. Daily measurements of foraging behaviour vary substantially in response to varying foraging conditions in space and time, and can effectively serve as indicators of variation in cattle weight gain. Implications. On-animal sensors that monitor foraging behaviour have the potential to transmit indicators to livestock managers in real time (e.g. daily) to help inform decisions such as when to move animals among paddocks, or when to sell or transition animals from rangeland to confined feeding operations.

Relationship between Sensitivity Tendency and Psychological Stress Reactivity in Healthy Students

This study examined the relationship between sensory processing sensitivity and psychological stress reactivity in 69 healthy Japanese university students. The Japanese version of the Highly Sensitive Person Scale and the Japanese version of the Adolescent/Adult Sensory Profile were used for subjective assessment. The Galvanic skin response was measured as an objective measure of stress responses while the participants were completing the Stroop task. The Wilcoxon signed-rank test, the Spearman rank correlation coefficient, and the Mann–Whitney U test were conducted for data analysis. The results demonstrated that there was no significant correlation between the Japanese version of the Highly Sensitive Person Scale and Galvanic skin response. However, there was a marginal trend toward significance between low registration in the Japanese version of the Adolescent/Adult Sensory Profile and Galvanic skin response (rs = 0.231, p < 0.10; rs = 0.219, p < 0.10), suggesting that self-rated sensitivity was not necessarily associated with objective measures. These results indicate that sensory processing sensitivity analyses require the consideration of the traits and characteristics of the participants and multifaceted evaluations using a sensitivity assessment scale other than the Japanese version of the Highly Sensitive Person Scale.
Tarsometatarsal Joint Preparation using a Modified Dorsal Approach vs Standard Approach: A Cadaver Study

Category: Midfoot/Forefoot Introduction/Purpose: Lisfranc injuries are a relatively common midfoot injury involving the tarsometatarsal (TMT) joint. Surgical fixation typically involves open reduction with internal fixation or primary arthrodesis of the joint(s). The standard surgical approach to the TMT joint involves two dorsal incisions however, a recent study has suggested the use of a modified single dorsal incision approach. The goal of this paper is to compare the total surface area of the joint that can be prepared for primary arthrodesis of the TMT using the standard vs modified single dorsal approach. Methods: Ten fresh frozen below-the-knee cadaver specimens were randomly assigned to receive either the standard or modified dorsal single incision operative approach to the TMT joint. Prior to initiating the study, specimens were inspected with fluoroscopic radiographs for preexisting pathology or prior surgical intervention. The joint surface was visualized and then underwent articular preparation as for a joint fusion. After adequate joint preparation, the TMT joint was disarticulated and the surface was photographed for image analysis. Using ImageJ, articular joint surface preparation areas were measured by two blinded reviewers. to assess the joint surface preparation and this was compared by surgical approach. Results: After ImageJ and Mann-Whitney U statistical analysis, there was no significant difference in the amount of joint prepared when comparing the standard versus modified dorsal approach for the first three TMT joints (p= 0.548, p=0.310, p= 0.548). The percentage of joint preparation utilizing the standard dorsal approach versus the modified dorsal approach for TMT joints one through three are as follows (percentages utilized are listed as the median value with its correlating range): First TMT- 67.6% (range 26%) by the standard approach versus 71.7% (range 9%) by the modified dorsal approach, second TMT- 67.9% (range 24%) versus 65.7% (range 12%), and third TMT- 65.9% (range 42%) versus 59.6% (range 24%). Table 1 summarizes our results between each operative approach. Conclusion: With our findings, we demonstrate that a modified single dorsal approach to the Lisfranc joint provided comparable joint preparation for primary arthrodesis as the standard dual incision approach. However, the modified dorsal approach may be beneficial in that it avoids creating a skin bridge which has potential for necrosis with the standard two incision approach. The authors believe the comparable joint preparation combined with its potential to alleviate soft tissue complications make the modified dorsal approach a viable surgical approach for a TMT arthrodesis.
Effects of Fish Oil on Biomarkers of Axonal Injury and Inflammation in American Football Players: A Placebo-Controlled Randomized Controlled Trial

There are limited studies on neuroprotection from repeated subconcussive head impacts (RSHI) following docosahexaenoic acid (DHA) + eicosapentaenoic acid (EPA) supplementation in contact sports athletes. We performed a randomized, placebo-controlled, double-blinded, parallel-group design trial to determine the impact of 26 weeks of DHA+EPA supplementation (n = 12) vs. placebo (high-oleic safflower oil) (n = 17) on serum concentrations of neurofilament light (NfL), a biomarker of axonal injury, and inflammatory cytokines (interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-a)) in National Collegiate Athletic Association Division I American football athletes. DHA+EPA supplementation increased (p < 0.01) plasma DHA and EPA concentrations throughout the treatment period. NfL concentrations increased from baseline to week 26 in both groups (treatment (<0.001); placebo (p < 0.05)), with starting players (vs. non-starters) showing significant higher circulating concentrations at week 26 (p < 0.01). Fish oil (DHA+EPA) supplementation did not mitigate the adverse effects of RSHI, as measured by NfL levels; however, participants with the highest plasma DHA+EPA concentrations tended to have lower NfL levels. DHA+EPA supplementation had no effects on inflammatory cytokine levels at any of the timepoints tested. These findings emphasize the need for effective strategies to protect American football participants from the effects of RSHI.

Evaluation Of Assessment Tools For Outcome Based Engineering Courses

The implementation of the Accreditation Board for Engineering and Technology (ABET) Engineering Accreditation Criteria 2000 (EAC 2000) into Mechanical Engineering undergraduate curricula is critical to the success of engineering education. The EAC Criteria 2000 emphasizes an outcome based system approach to engineering education. To ensure the quality of the outcome based mechanical engineering program, faculty need to provide assessment tools to measure outcomes of each undergraduate engineering course. The faculty at Alabama A&M University adopted the SEAARK teaching approach for instruction and teaching. SEAARK stands for Knowledge, Repetition, Application, Analysis, Evaluation and Synthesis in reverse order. It was based on Bloom’s taxonomy. SEAARK starts from the basics to the complex levels of learning. In the past few years, the development of the SEAARK teaching method, mapping of course objectives to ME program objectives has been completed. Mapping of the course contents to ABET criteria and assessment tools were also developed. Useful application data has been collected. This paper describes the evaluation of assessment tools for undergraduate mechanical engineering courses, at Alabama A&M University. Specific data for Fluid Mechanics class is presented. Development, modification and evaluation of assessment tools for course contents are discussed. This paper describes the assessment tools and evaluation of an outcome based engineering undergraduate mechanical engineering course, in particular, Fluid Mechanics, at Alabama A&M University. SEAARK teaching method, mapping of the course contents to criteria (a-s) and assessment tools are discussed. Collected data in the past five years for the Fluid Mechanics class indicated that the student learning performance can be well assessed. The teaching quality and learning outcome can be well measured using these assessment tools. The data give us confidence that the development of assessment tool for the outcome based engineering courses is working in the positive direction.
How does customer engagement value occur in restaurants?A stimulus-organism-response(S-O-R) perspective

ABSTRACT The customer engagement value plays a vital role in the service industry. This study aims to explain how the customer engagement value occurs through restaurants using the stimulus-organism-response approach (S-O-R), based on environment-related dimensions (i.e. physical environment), brand-related feelings (i.e. love), and customer experience. 685 respondents were surveyed online, and data were analysed through structural equation modeling. The research findings show that physical environment positively affects brand love, brand love positively affects customer engagement value dimensions and also mediates the relationships between physical environment and customer engagement value, and customer experience moderates the relationship between physical environment and brand love. Restaurants can utilize our results to gain customer engagement value by creating love toward their brands through the physical environment; moreover, future research can further develop the customer engagement value theory and approach in light of our results.
The effect of traffic loading to buried water mains in partially saturated soils

Mosl of the water pipelines are buried in unsaturated soils. However, the design considerations and analytical solutions for buried water mains assume that the soil is either dry or fully saturated. In unsaturated soils, such assumption often leads to incorrect estimation of induced deformation/stress on buried water pipes by external loads such as from traffic loading. These different anticipated loads are generated because the water meniscus between soil particles creates an additional normal force due to suction, which in turn makes the soil stiffer and stronger. Such stiff soil could contribute to absorb external energy induced by traffic loading (i.e. less pipe mobi lize), while providing additional support to the pipe by restra ining ils deformation. In the current study, FE analyses arc conducted to investigate the effects of traffic loading on the stress distribution of water mains buried in non-dry soil conditions using advanced constitutive soil models. Results showed that the impact of traffic loads on pipes buried in partially saturated soils is substantially different than that result in dry or fully saturated soils. The effects of soil plasticity on buried pipelines subjected to traffic loading are also discussed in comparison with the predictions from the analytical models. These findings are useful to include in current buried pipe design practices by accounting the effect of unsaturated soil behaviour.

Modeling and Control of Power Electronics Based DC Networks

The introduction of power electronic converters provides flexibility in the transformation of electrical energy such as ac-dc and dc-ac. For this reason, dc networks are becoming more popular in applications such as electric aircraft, navy ships, long distance power transmissions, and future microgrids in outer space. These systems are typically composed of multiple sources (ac or dc) and multiple loads (ac or dc) interconnected together through power electronics. In this work, modeling methods aimed at efficient real time simulation, stability analysis, and controller design for dc networks are presented. Real time simulation is a fundamental tool used in industry to test hardware and/or software without the need of the actual system. For example, Hardware-inthe-Loop (HIL) techniques are commonly used to test a control unit for a vehicle, power converter, etc. The increase in switching frequency of the power electronics (due to new devices such as SiC/GaN), decreases the time step needed to simulate these systems. For this reason, FPGAs are being commonly used for real time simulation. Nevertheless, the low level programming required introduces challenges in the modeling and implementation. Methods and algorithms are proposed to efficiently model the power devices including ‘on’ characteristics. In addition, a discussion of machine simulation including saturation and its implementation in FPGA are discussed. ii The use of power electronics to deliver power to loads (e.g. motors, dc electronic loads, etc.) introduces a negative impedance effect as seen by the network. This effect can potentially cause instability problems in the system. These types of loads are commonly referred in literature as Constant Power Loads (CPLs). To study the stability of dc networks with CPLs, a method is proposed based on Linear Matrix Inequalities (LMIs) and Semidefinite Programming (SDP). The advantage of the proposed method relies on the use of static feedback without the need of knowing the load power and/or its derivatives. Lastly, the modeling, simulation, and control of High Voltage DC Networks is presented. In these systems, Modular Multilevel Converters (MMCs) are typically used as an interface between the ac and dc networks. These types of converters can utilize hundreds to thousands of switches. Therefore, the simulation, offline and real time, is a main challenge. In addition, the circulating current through each arm affects the power losses in the power devices and causes larger current and voltage stress on the passive components. In this case, a controller is proposed to eliminate this oscillation and a platform for efficient simulation of MMCs is developed. Real time simulation and HIL validation of the controller are presented.
Effect of the Cu/ZnO/SBA‐15/kaolinite preparation method on the catalyst structural properties and catalytic performance at CO2 hydrogenation at low pressure

Carbon dioxide catalytic hydrogenation to methanol in the presence of nanocatalysts has been recognized as one of the most effective ways to fix and utilize the emitted CO2. In this study, Cu/ZnO/SBA‐15 catalyst has been synthesized by three different methods: “impregnation‐sol–gel autocombustion” method, impregnation method and direct synthesis method using triblock copolymer Pluronic P123 as a template. Cu/ZnO/SBA‐15 catalysts comprising kaolinite clay have been used in CO2 hydrogenation to methanol for the first time to make the methanol synthesis more cost‐effective. The performance of catalysts upon hydrogenation of CO2 was evaluated in a fixed‐bed tubular micro‐activity reactor at 20 bar with H2 to CO2 molar ratio 3 to 1 and 250°C. Results showed that the highest methanol production, with STY of 36 mg CH3OHh−1gcat−1, could be obtained using the catalyst prepared by “impregnation‐sol–gel autocombustion”. This synthesis method allowed to obtain catalyst with the smallest crystallite size and a good dispersion of the active phase over and into SBA‐15. The CO2 conversion reached 15.9%, which is close to conversion level provided by commercial Cu catalyst.
Entrepreneurial skills in university degrees

Purpose: From a skills perspective, the academic field of entrepreneurship has grown to become a key element in university studies. Determining whether these skills exist among university students and how to foster them is a key in higher education. To this effect, the aim of this study is to determine the entrepreneurial skills’ level among the students on the different bachelor’s degrees taught at the Faculty of Business and Economics Sciences of University of Girona. Design/methodology/approach: Information about the skill level was collected using a skills model called Tricuspoid, which was specifically designed for the self-assessment of entrepreneurial skills. Information about students’ sociodemographic, professional and educational profile was collected using a self-administered complementary questionnaire. Bivariate analysis and statistical contrast were applied. Findings: Being a man, doing sport, balancing studying with paid work and accessing university studies via the vocational training pathway are indicators of a greater entrepreneurial capacity. On the other hand, being a woman, accessing university studies via baccalaureate or having no knowledge of English, however, are factors associated with a deficit in entrepreneurial talent. Originality/value: Considering the fact that attitude to entrepreneurship can be modified through educational interventions, identifying these factors enables us to formulate guidelines for teaching activities that increase students’ entrepreneurial and intrapreneurial capacity for a better integration for our students into the job market.
Metformin and Cancer, an Ambiguanidous Relationship

The deregulation of energetic and cellular metabolism is a signature of cancer cells. Thus, drugs targeting cancer cell metabolism may have promising therapeutic potential. Previous reports demonstrate that the widely used normoglycemic agent, metformin, can decrease the risk of cancer in type 2 diabetics and inhibit cell growth in various cancers, including pancreatic, colon, prostate, ovarian, and breast cancer. While metformin is a known adenosine monophosphate-activated protein kinase (AMPK) agonist and an inhibitor of the electron transport chain complex I, its mechanism of action in cancer cells as well as its effect on cancer metabolism is not clearly established. In this review, we will give an update on the role of metformin as an antitumoral agent and detail relevant evidence on the potential use and mechanisms of action of metformin in cancer. Analyzing antitumoral, signaling, and metabolic impacts of metformin on cancer cells may provide promising new therapeutic strategies in oncology.
