Experiments and forest economic questions During the last decades experiments have gained great importance in economics. These experiments deal with questions that are of significance for forest economic research, too. Timber production, for example, is characterised by long-term decisions and, in addition, forestry produces important public goods. In this article the experimental method is introduced. Furthermore, experimental findings are presented, e.g., concerning time preferences and externalities, and possible applications for the study of forest product markets and institutions are outlined.

Bileaflet Valves

The hinge design of a new bileaflet valve (Bicarbon) is presented in relation to the long-term durability characteristics. Theoretical considerations supported by experimental findings, lead to the identification of two different wear mechanisms acting in bileaflet valves, i.e. impact and friction wear. Impact wear, caused by the collision between the hinge stops and inflow surface of the leaflet pivots, is the predominant phenomenon; it is mostly influenced by the design of the coupling elements. The wear due to friction is significantly less important, given a proper kinematic coupling and a thorough washout. These different mechanisms can significantly affect the wear resistance and long-term reliability of bileaflet valves; therefore, they have been properly taken into account in designing the new valve model. The safety of the overall material and design solutions adopted in the Bicarbon valve has been confirmed by extensive accelerated durability tests resulting in no mechanical failure or loss of functionality

Heritable Effects

Abstract Most surgical procedures require general anesthesia, which is a reversible deep sedation state lacking all perception. The induction of this state is possible because of complex molecular and neuronal network actions of general anesthetics (GAs) and other pharmacological agents. Laboratory and clinical studies indicate that the effects of GAs may not be completely reversible upon anesthesia withdrawal. The long-term neurocognitive effects of GAs, especially when administered at the extremes of ages, are an increasingly recognized health concern and the subject of extensive laboratory and clinical research. Initial studies in rodents suggest that the adverse effects of GAs, whose actions involve enhancement of GABA type A receptor activity (GABAergic GAs), can also extend to future unexposed offspring. Importantly, experimental findings show that GABAergic GAs may induce heritable effects when administered from the early postnatal period to at least young adulthood, covering nearly all age groups that may have children after exposure to anesthesia. More studies are needed to understand when and how the clinical use of GAs in a large and growing population of patients can result in lower resilience to diseases in the even larger population of their unexposed offspring. This minireview is focused on the authors’ published results and data in the literature supporting the notion that GABAergic GAs, in particular sevoflurane, may upregulate systemic levels of stress and sex steroids and alter expressions of genes that are essential for the functioning of these steroid systems. The authors hypothesize that stress and sex steroids are involved in the mediation of sex-specific heritable effects of sevoflurane.

The research aims to provide broad access to education for people in the Industrial Revolution 4.0 through various higher education institutions that actively participate using the Blended Learning model. The long-term goal of this research is to develop innovative and flexible learning models based on Smart Classroom. System design in this study was developed to realize a balance between virtual teaching (virtual class) and face-to-face (physical class) that takes place at the same time using the Live Video Webcasting service. The research method uses a quantitative approach and the type of research is R & D adopting the Thiagarajan 4D development model. This research produces a Smart Classroom system based on Streaming Webcast through several stages, namely: (1) System Design, (2) System Creation, (3) System Testing. This developed system allows interaction in learning in the physical class as well as teaching in a virtual class remotely.Keywords: Revolusi Industri 4.0, Blended Learning, Smart Classroom, Live Video Webcasting.

ABSTRACT：It introduces a kind of an Automatic Calibration System, especially for long-term drift of oil tank gauging system. long-term drift serious influence on measuring the accuracy and reliability of the system. With theory of Hydrostatic Tank Gauging[1]（HTG），as soon as the long-term drift occurring, the detection drift of oil pressure valueΔp will drift，and soon other the parameters of tank Gauging will be occurred. Because the value of Δp is difficult to directly determine, This paper puts forward a kind of automatic calibration method to obtain Δp according to the fuel level drift Δh) indirectly,By means of the HTG double level switches and fuzzy control theory. At last, by MATLAB simulation verify the correctness of the system design.

Richard Schmidt and I titled our article “New Conceptualizations of Practice: Common Principles in Three Paradigms Suggest New Concepts for Training” to reflect our view that prevailing ideas about how to optimize teaching, learning, and practicing were, in our words, “at best incomplete, and at worst incorrect.” We argued that teachers and trainers were susceptible to being misled by two commonsense assumptions—namely, that procedures that enhance performance during training are the procedures of choice and that the context of training needs to match in detail the posttraining context that is the target of training. A variety of then-recent experimental findings challenged both assumptions and demonstrated, in particular, that procedures posing certain difficulties and appearing to slow the rate of learning often enhanced long-term retention and transfer of to-be-learned skills and knowledge. Given the parallel nature of such findings for both motor and verbal learning, we concluded that principles of considerable generality could be deduced to upgrade teaching and training.

Consideration of the implications of solar UV exposure on public health during extreme temperature events is important due to their increasing frequency as a result of climate change. In this paper public health impacts of solar UV exposure, both positive and negative, during extreme hot and cold weather in England in 2018 were assessed by analysing environmental variations in UV and temperature. Consideration was given to people’s likely behaviour, the current alert system and public health advice. During a period of severe cold weather in February-March 2018 UV daily doses were around 25–50% lower than the long-term average (1991–2017); however, this would not impact on sunburn risk or the benefit of vitamin D production. In spring 2018 unseasonably high temperatures coincided with high UV daily doses (40–75% above long-term average) on significant days: the London Marathon (22 April) and UK May Day Bank Holiday weekend, which includes a public holiday on the Monday (5–7 May). People were likely to have intermittent excess solar UV exposure on unacclimatised skin, causing sunburn and potentially increasing the risk of skin cancers. No alerts were raised for these events since they occurred outside the alerting period. During a heat-wave in summer 2018 the environmental availability of UV was high—on average of 25% above the long-term average. The public health implications are complex and highly dependent on behaviour and sociodemographic variables such as skin colour. For all three periods Pearson’s correlation analysis showed a statistically significant (p<0.05) positive correlation between maximum daily temperature and erythema-effective UV daily dose. Public health advice may be improved by taking account of both temperature and UV and their implications for behaviour. A health impact-based alert system would be of benefit throughout the year, particularly in spring and summer.
