Recent Developments in Feeding Beef Cattle on Grass Silage-Based Diets

Key points: High digestibility grass silage with moderate concentrate supplementation can sustain a large proportion of the cattle performance achieved on high concentrate diets. Increasing concentrate supplementation reduces the importance of grass silage nutritional value. Subsequent compensatory growth diminishes the advantage of concentrate supplementation of young cattle. Meat quality and fatty acid composition can be influenced by grass silage-based diets

A review of cryogenic testing performed by the thermochemical test branch, Manned Spacecraft Center in support of Apollo 13 and14

The Apollo 13 anomaly provided considerable impetus for a variety of types of cryogenic and ignition tests. The logic of the various test program designs, the test techniques, and their final impact upon the investigation findings are described. In addition, several test programs initiated to determine the thermal performance and general performance characteristics of the redesigned Apollo 14 cryogenic storage system are presented

Vaccine Myths: Setting the Record Straight

Despite their standing as one of the most remarkable public health achievements, vaccines have been surrounded by dangerous myths since the development of the smallpox vaccine in the 18th century. In recent decades, with the publication of a fraudulent article linking vaccines to autism, the involvement of celebrities in the debate, and the rise of the internet and social media as sources for information for patients, these myths have become more widespread. This paper reviews four common vaccine myths: vaccines cause autism, vaccines are not safe, too many vaccines are given too soon, and the influenza vaccine is not necessary. For each of these myths, we review the origin and spread of misinformation. The authors then present the scientific evidence against each myth. Extensive research has found no link between vaccines, and particularly the MMR vaccine or the preservative thimerosal, and autism. The U.S. and world health agencies have effective mechanisms in place to review and monitor vaccine safety. These systems have worked to detect and evaluate even rare vaccine adverse events. The recommended vaccine schedule is safe for infants’ immune systems. The flu vaccine is an essential tool in the fight against the seasonal influenza deaths. A consequence of these myths is that parents are choosing to delay or refuse recommended vaccines for themselves and their children. This has resulted in outbreaks of measles, pertussis, H. influenza type b, varicella, and pneumococcal disease in the United States. Unvaccinated and undervaccinated children risk contracting the disease themselves, and pose a risk to their community as herd immunity decreases. It is important to explore and refute the myths leading to decreased vaccination rates, so health care providers and parents can make educated decisions to protect children and ensure public health

Therapeutic Jurisprudence and the Appellate Courts: Possibilities

Therapeutic jurisprudence has multiple possibilities, provided it does not add another layer of cost, delay, and time to the process. First, we should see a reduced number of cases for the appellate court to decide, fewer remands and secondary appeals, the streamlining of appeals through partial resolution of issues, the satisfaction of parties\u27 underlying needs and interests, and the reduction of the time a case spends on appeal. Second, the outcome does not have to become part of the case law that applies to similar cases, possibly establishing negative precedent. Third, mediation allows personal healing and the development of positive, achievable values. Respect for the law and the legal process can develop in a distrustful culture

A Value Focused Thinking Approach to Software Interface in a Complex Analytical Domain

The intelligence community is faced with an extensive amount of data. Software programs are being developed to examine this issue of data overload and to develop solutions. The responsibility of making the final software decision lies on the analyst, therefore, the interface is the key to linking the intelligence data to the processing and results, If the interface is difficult and complex, the software will be less likely to be used. A methodology must be created which can objectively evaluate the effectiveness of the interface, This methodology will also measure the improvements in the interface\u27s effectiveness that result when various changes are made to the original software interface, Value focused thinking (VFT) is a proven methodology that can be applied to this problem, VFT provides an objective methodology to identify the values of an organization, Its hierarchical structure is well suited for handling multi-objective problems, such as identifying the values of software interfaces, The values can be measured and put to a common scale, allowing their contribution to the overall objective to be evaluated, By assigning quantifiable measurements to the components, the multi-objective goal can be evaluated and insight can be provided to the decision makers involved with the intelligence software, VFT was applied to determine what is valued in software\u27s interface to members of the intelligence community, With these values identified, a software that is under development was evaluated against the hierarchy, This provided insight into where improvements could be made to the interface that would provide the greatest benefit, The VFT process also allows for the decision maker to continually reevaluate the software against the hierarchy, enabling continual improvement on the interface while maintaining the values of the intelligence community

A system for synthetic vision and augmented reality in future flight decks

Rockwell Science Center is investigating novel human-computer interaction techniques for enhancing the situational awareness in future flight decks. One aspect is to provide intuitive displays that provide the vital information and the spatial awareness by augmenting the real world with an overlay of relevant information registered to the real world. Such Augmented Reality (AR) techniques can be employed during bad weather scenarios to permit flying in Visual Flight Rules (VFR) in conditions which would normally require Instrumental Flight Rules (IFR). These systems could easily be implemented on heads-up displays (HUD). The advantage of AR systems vs. purely synthetic vision (SV) systems is that the pilot can relate the information overlay to real objects in the world, whereas SV systems provide a constant virtual view, where inconsistencies can hardly be detected. The development of components for such a system led to a demonstrator implemented on a PC. A camera grabs video images which are overlaid with registered information. Orientation of the camera is obtained from an inclinometer and a magnetometer; position is acquired from GPS. In a possible implementation in an airplane, the on-board attitude information can be used for obtaining correct registration. If visibility is sufficient, computer vision modules can be used to fine-tune the registration by matching visual cues with database features. This technology would be especially useful for landing approaches. The current demonstrator provides a frame-rate of 15 fps, using a live video feed as background with an overlay of avionics symbology in the foreground. In addition, terrain rendering from a 1 arc sec. digital elevation model database can be overlaid to provide synthetic vision in case of limited visibility. For true outdoor testing (on ground level), the system has been implemented on a wearable computer

Charting Complex Changes: Application of the eHealth Implementation Toolkit (e-HIT) in the Delivering Assisted Living Lifestyles at Scale (dallas) Programme

The 'dallas' (Delivering Assisted Living Lifestyles at Scale) programme is a UK-wide digital healthcare initiative that has been designed to support independent living, enhance preventative care, and improve lifestyles by harnessing the potential of e-health technologies and digital services. This short paper presents a brief update on one strand of the University of Glasgow evaluation of the dallas programme. We have used the e-Health Implementation Toolkit (e-HIT) to investigate processes involved in the implementation of e-health tools and digital services being developed and deployed across the dallas communities and to assess 'distance travelled' by communities from baseline to midpoint of a three year programme. Qualitative data analysis was guided by the Normalisation Process Theory (NPT) and Framework Analysis. The e-HIT scores indicated that the dallas communities had underestimated the amount of work involved in implementing at scale. Qualitative data analysis showed that communities have successfully navigated barriers in order to make significant progress in strategic areas, including the development of new models of partnership working resulting in brand recognition and agile service design. The dallas communities are now sharing lessons learned and generating new professional knowledge, skills and understanding across several key strategic areas required for operationalising the implementation of e-health technologies and digital services at scale. The new knowledge being generated through the dallas programme will contribute to the ongoing transformation of digitally enabled healthcare based on more personalised flexible models of provision which resonates with the current e-health policy environment
