Enzyme Application

Enzymatic catalysis is one of the main pillars of sustainability for industrial production. Enzyme application allows minimization of the use of toxic solvents and to valorize the agro-industrial residues through reuse. In addition, they are safe and energy efficient. Nonetheless, their use in biotechnological processes is still hindered by the cost, stability, and low rate of recycling and reuse. Among the many industrial enzymes, fungal laccases (LCs) are perfect candidates to serve as a biotechnological tool as they are outstanding, versatile catalytic oxidants, only requiring molecular oxygen to function. LCs are able to degrade phenolic components of lignin, allowing them to efficiently reuse the lignocellulosic biomass for the production of enzymes, bioactive compounds, or clean energy, while minimizing the use of chemicals. Therefore, this review aims to give an overview of fungal LC, a promising green and sustainable enzyme, its mechanism of action, advantages, disadvantages, and solutions for its use as a tool to reduce the environmental and economic impact of industrial processes with a particular insight on the reuse of agro-wastes.

We appreciate the concerned letter of Dr Jacobs and his thoughtful questions arising both from his knowledge of the recommendations and public health issues, as well as those of private practice. The cost of vaccines is an issue with which we must all be concerned. By highlighting the importance of childhood immunization the Clinton administration has engendered interest and, thus, optimism that efforts toward reducing the cost will be successful. However, we should remember that the many excellent studies that have analyzed the reasons why children are not being vaccinated have shown that cost is not the major factor, but access, difficulties, and obstacles, real and perceived, to obtaining immunizations are.

Survey Approach

There is a growing demand for sustainable retirement villages in Australia due to an increasing number of ageing population and public acceptance of sustainable development. This research aims to gain a better understanding of retirees’ understanding about sustainable retirement living and their attitudes towards sustainable developments via a questionnaire survey approach. The results showed that the current residents of retirement villages are generally very conscious of unsustainable resource consumption and would like their residences and community to be more environmentally friendly and energy efficient. The cost of energy supply is a concern to majority of respondents. However there is a certain level of concerns from residents too on the extra cost of going green in their residence. Education is required to residents about recycling household waste and how to use available facilities. A better understanding of retirees’ awareness and attitudes towards sustainability issues helps to improve the sustainable developments of retirement villages in the future.

Safeguarding the rights of minorities is crucial for just societies. However, there are conceivable situations were minority rights might seriously impede the rights of the majority. Favoring the minority in such cases constitutes a violation of utilitarian principles. To investigate the emotional, cognitive, and punitive responses of observers of such utilitarian rule transgressions, we conducted an online study with 1004 participants. Two moral scenarios (vaccine policy and epidemic) were rephrased in the third-party perspective. In both scenarios the protagonist opted against the utilitarian option which resulted in more fatalities in total, but avoided harm to a minority. The scenarios varied in whether the minority would have been harmed accidentally or deliberate. The majority of participants chose not to punish the scenarios’ protagonists at all. However, 30.5% judged that protecting the minority over the interests of the majority when only accidental harm would have occurred (vaccine policy) was worthy of punishment. In comparison, only 11.5% opted to punish a protagonist whose decision avoided deliberate harm to a minority at the cost of the majority (epidemic). Emotional responses and appropriateness ratings paralleled these results. Furthermore, complex personality × situation interactions revealed the influence of personality features, i.e., psychopathy, empathy, altruism, authoritarianism, need for cognition and faith in intuition, on participants’ responses. The results further underscore the need to consider the interaction of situational features and inter-individual differences in moral decisions and sense of justice.

The Cost

The cost of many coastal projects is often increased by the expensive beach repair and maintenance required to remedy the destabilising effects of structures on the adjoining coastline. Physical and/or mathematical models have been developed for use in planning these projects in order to predict and quantify the effects of marine sediment transport on the coastal topography. Such models need to be calibrated against prototype data and one method of gauging volumetric sediment movement is by successive bathymetric/ topographic profiting surveys which are performed seasonally and annually. Since large quantities of sediment are related to small changes in bed elevation it is clear that this profiling needs to be done with the utmost precision* The areas most affected extend from the beach through the surf zone to water depths of about 25 metres. The surf zone in particular is a dynamic and hostile area which falls outside the traditional activities of both the hydrographic and land surveyors. Consequently innovative methods, deficient in sound survey principle and practice, have often been pursued in this area without any attempt being made to assess the tolerance on the data. This paper attempts to show that it is possible to produce reliable and verifiable results to the required accuracy by using conventional survey equipment and techniques, also by taking the necessary precautions against the many possible sources of survey error. The procedures and techniques described have evolved from NRIO's involvement over the past decade in major projects at Richards Bay, Durban, Koeberg and in False Bay. The results of a recent verification investigation are fully reported in this paper.

Energy Transportation

The transportation sector already accounts for 14% of global greenhouse gas emissions. Therefore, controlling carbon emissions in the transportation sector has become a top priority for China and other countries around the world. In addition to the technological development of clean energy transportation, the most critical aspect of the globalization of new energy transportation industry and market is the optimization of access routes. This paper will be based on road travel time estimation and optimal path selection of energy efficient transportation research hotspots. Firstly, the accuracy of road travel time estimation is improved according to the basic law of traffic flow. At the same time, this paper defines the optimal route into two cases of shortest path and shortest time for solving. Finally, the actual solution process is given according to the actual problem, as well as the optimal route, aiming to promote the strong development in the field of intelligent navigation system and energy-efficient transportation.

The therapeutic landscape of multiple sclerosis (MS) has been transformed by the advent of several new monoclonal antibody (MAb) therapies that can potentially lead to full stabilisation of detectable disease activity. Natalizumab, alemtuzumab and ocrelizumab are currently licensed MAbs for the treatment of MS. Daclizumab was licensed for the treatment of MS, although it has been recently withdrawn from the market by the manufacturer. Most patients are initially managed with first-line treatments, and, if disease breakthrough occurs, are escalated to a stronger compound, yet the available evidence indicates an early window of therapeutic opportunity for MAbs to exert most of their efficacy. It is important to balance the superior efficacy of MAbs compared with injectable treatments against more serious side effects, although these are well recognised and can be monitored where indicated and treated. In particular, the risk of progressive multifocal leucoencephalopathy with natalizumab can be managed by screening potential patients for the John Cunningham virus. The MAbs also have the benefit of convenience to patients compared with daily or weekly treatments since they are given via less frequent administration. The cost of these treatments, compared with other therapies, may be an important issue in many countries where healthcare budgets are under pressure. The complex decision of choosing the best treatment for an individual should be made jointly between the doctor and the patient after careful consideration of the many factors to be weighed.
