The requirements imposed on schools and the competencies of teachers change depending on the development of society, and currently their constant growth is considerable. These facts lead to the need to continuously innovate pre-service teacher training, especially with a focus on creating professional digital literacy. The creation of a proposal of an optimal model of pre-service teacher training in the field of teacher trainees’ professional didactic-technological competency development was the subject of the research, which is described in the article. The described research examined the importance of the integration of various kinds of digital didactic tools into pre-service teacher training curricula with regard to the successful performance of the teaching profession. The necessary research data were obtained on the basis of screening the opinions of teacher trainees in Slovakia and the Czech Republic (n = 280). The respondents of the research survey expressed, in terms of various aspects, their opinions on the importance of integrating the issue of working with specified kinds of the given digital means into the curricula of teacher trainees’ study programs. The obtained research data were analysed depending on three segmentation factors of the respondents, which were the nationality of the student (i.e., the COUNTRY of his/her study), the GENDER of the respondent, and the combination of these two factors, i.e., COUNTRY X GENDER. According to the achieved results, there is a need to include or strengthen the teaching of software applications such as ActivInspire, FreeMind, SMART Notebook, Google Docs and, if possible, Prezi and Mindomo, and also a need to emphasize the methodological aspects of the use of these technical means in teaching.

The Impact

The processing of polymetallic materials provides some challenges to every flowsheet. Within Aurubis Cu-Pb-metallurgical flowsheet, a broad range of raw materials and intermediates are processed. Continuous improvements are required to adapt the flowsheet according to the changing material quantity and quality. Therefore, thermodynamic modeling is the desired and most efficient way to conduct scenario analysis. Hence, databases and software are becoming better and better as the acceptance of this method increased. Further understanding is promoted by conducting experimental test work to validate the calculated results. In this research work, the impact of various oxygen potential on the formation of the condensed phases’ slag, matte, speiss and crude lead were investigated. A frequent check of slag metallurgy, in particular, the iron and lead concentration, provide feedback if the metallurgical process is operating at the right oxygen potential. Following, the calculated distribution coefficients for Cu, Pb, As, Sb, Sn and Ni between matte/speiss and speiss/lead are discussed.

Improving the food system sustainability and security is becoming an urgent global challenge. In this regard, one of the most effective routes is the shift of the human diet toward healthier and more sustainable consumption, involving in particular the prevalence of plant-based raw food materials. Controlled hydrodynamic cavitation (HC) technologies could help considerably in this transition. HC techniques are gaining increased scientific interest, and are quickly spreading across a wide range of technical fields, recently showing surprising performances with biological raw materials related to the food, agricultural and forestry sectors and resources. HC processes enjoy recognized advantages in the acceleration of the processing steps of plant-based food, the extraction of valuable bioactive compounds, the reduction and the valorization of waste streams, as well as the superior efficiency in resource use, energy consumption, process yield, and exergy balance than competing processes. Thus, HC is very promising candidate to help addressing the water-energy-food nexus, and, ultimately, sustainability. Findings obtained from direct experimental trials and recent literature concerning the applications of HC to food processing, provide a strong basis for novel investigation aimed at standardization, starting from the identification of the most suitable devices and the optimal processing parameters, eventually oriented to further spreading of HC applications.

The demand for amplang crackers is now increasing. However, the price of its raw material, mackerel fish, is generally higher compare to other fishes, causing the higher cost of this type crackers production. Effort to explore other fish as an alternative raw material is required to overcome the problems. Catfish is one of the choices to be used as raw material since this fish is more available in a market in a lower price, but the protein properties of this fish is different to mackarel, which will be possible to affect the nature of the crackers obtained. To produce catfish amplang crackers to be similar to common amplang product, it is necessary to find out the right composition of catfish and tapioca flour used. Therefore, the purpose of this research was to characterize physico-chemically and organoleptically, the catfish amplang crackers made under different ratio of fish flesh and starch. The experiment was designed using completely randomized design. Physico-chemical data obtained were analyzed using ANOVA, while the organoleptic test data were examined using chi-square method. The effectiveness test was carried out to find the proper ratio of raw materials composition used. The results showed that the higher the ratio of the fish flesh and the starch composition, the lower the texture value of the crackers as an indication of the decrease of its crispness. Although the lightness of the crackers was lowered by the addition of more starch to the dough, its linear expansion and hygroscopicity were not affected. The results of organoleptic test showed that the panelist was prefer to a higher crispness of crackers. The most preferable cracker was the one with 1:2.25 ratio of catfish flesh and starch, showing the characteristic of 1.80% moisture, 2.08% ash, 5.75% protein, 23.55% fat, and 66,93% carbohydrate.

The economic value of the Abaca banana is on the trunk which contains fiber for valuable textile and paper industry raw materials. The multipurpose fiber and its prospects are quite good, so the abaca plant gets a lot of attention from various community groups both private, state-owned, cooperative and farmers. Propagation through multiplication humps is very low, planting material is easily damaged in transportation, is not durable and requires large space so that transportation costs are high. One alternative to overcome the provision of healthy, large and fast seedlings is to use seedlings from tissue culture. The aim of the study is to get the right thiamin and leaf fertilizer concentrations at the acclimatization stage. The experimental design used was a 2-factor Complete Randomized Design, Thiamin concentration (1 ml / l, 2 ml / l, 3 ml / l) and leaf fertilizer (0.5 ml / l, 1 ml / l, 1.5 ml / l). The data obtained were analyzed for diversity at 5% level and further tests using Duncan Multiple Range Test (DMRT) level of 5%. The results showed no interaction between thiamin and leaf fertilizer, Thiamin 2 ml / l gave the best results on all parameters and 1.5 ml / l leaf fertilizer could increase plant height and the number of leaves of abaca banana plants.Keywords: Thiamin, leaf fertilizer, abaca banana, acclimatization

With increasing concerns about global warming, and the cement plants emitting huge CO2, it is necessary to know how the CO2 emits and how much the CO2 emits due to cement manufacture in both direct and indirect ways. A precise method to calculate CO2 emissions including three processes was established in this paper and a case study was provided. From the case of LQDX plant, we can see the amount of CO2 emissions at the right level. The summary of CO2 emissions is consisted by emissions from raw materials, fuels and electricity. The direct CO2 emissions are 0.822 ton CO2 per ton clinker, and the total CO2 emissions are 0.657 ton CO2 per ton cement in this study. Therefore, the way that CO2 emissions due to cement manufacture was pictured and then measured. An approach provides a basic framework to identify various situations in different cement plants in China and other in the rest of the world. The framework would be useful in quantitatively evaluating CO2 emissions for government to know precisely CO2 emissions in cement plants.

Abstract In recent years, market surveys on sustainable seafood consumption have analysed Chinese people’s willingness to purchase ecolabelled seafood produced and imported into China. Endogenous and exogenous determinants are thereby unveiled to explore Chinese consumers’ sustainability consciousness, purchasing decisions, and the means of bridging the divide. This article builds upon and adds to these empirical findings with a market-based and information lens. It draws inspiration from analysing the growing interest of younger and middle-class consumers in acquiring seafood information; integrative sourcing and marketing strategies of intermediary businesses to deliver such information; and awakening of public regulators to the imperative of realizing the right to information of less-informed parties. Instead of segregating these stakeholders along a linear supply chain, the study emphasizes the deepening of a consumer-centric information network underpinned by supply chain transparency and traceability. It thus aims to inform a steady shift from a production-oriented to a consumer-oriented seafood management paradigm through systematic reforms of China’s consumer law. To encourage and empower sustainable consumption, the ‘consumer’ notion needs proper broadening and consumers’ right to know should be recognized as a judicial and self-contained legal entitlement with enforcement safeguards.

: Beauty and wellness remain for both women and men an important target also because global attractiveness is considered a cue indicating the ability to maintain beauty and wellness. Consequently neuromarketing has occurred as an innovative mean to interact with consumer's trend, actually looking for high-quality and natural cosmetics and food. By the biometric studies, in fact, it seems possible to verify the consumers’ willingness to buy the right products they are looking for. On the other hand, customers are requesting cosmeceuticals and nutraceuticals acting positively on the superficial appearance of face and body, seem to be able to boost the immune system also, limiting the stress conditions. This general disease is induced by the actual way of living on a planet invaded by a great quantity of waste released from human’s activities. The consequent pollution alters the ecological balance of the body, influencing negatively the life of animals and plants also. Thus, the induced stress, further increased by the COVID-19 spread, could change the human brain' neural conditions. Consequently, in humans the production of both neurons' stem cells and cortisol could decrease, while in plants, the patterns of growth could affect the leaf cuticle and stomatal conductance. Thus brain, under psychosocial stress, actively demands energy from the body, eliciting a marked increase in eating by a major carbohydrate intake which sacrifices the requirements of other organs. In any way, pollution has wide-ranging adverse health and social effects, further worsened by an increased worldwide aged population who, requiring more food and goods, increases the waste production. What the proposed solution? To change the way of consuming and producing, it is necessary to optimize the material resource, minimizing waste that should be recycled and reused by a green economy approach. So doing, it could be possible to realize a new industrial Renaissance reducing consumption of water, energy and natural raw materials. Thus the necessity to use sustainable technologies and materials for maintaining human wellbeing in an environment in which the species' biodiversity could be assured. At this purpose, chitin nanofibrils(CN), nano-lignin (NL) and their derived compounds have been proposed to make nanoparticles (NPs) by the use of water as solvent. These NPs, loaded with different active ingredients, may be embedded into innovative natural or man-made polymers and used to make biodegradable carriers in the form of non-woven tissues and films. Depending on the polymers and on the actives loaded into the fibers, these new vehicles may be used to produce smart cosmeceuticals, nutraceuticals or advanced medications. It is interesting to underline that all these innovative NPs and tissue/films can be produced by natural polymers and ingredients, obtained from waste materials and produced by sustainable technologies at low consumption of water and energy, according to the new green economy.

In the JIT assembly system, if any supplier does not deliver the raw materials or components on time, or in the right quantity, the core manufacturers will not assemble on the schedule, which will bring great loss to the whole supply chain and greatly reduce the competitiveness and collaboration of the entire supply chain. Based on a survey on supply chain collaboration and operation model, supply logistics in JIT environment are analyzed from both the inside and outside system with the research goal of coordinating the upstream supply logistics. In order to help manufacturers implement the JIT production, the VMI-Hub operation mode is proposed from the aspect of inside system, and from outside system, cross-docking dispatch operation mode is considered to coordinate the supply logistics in assembly system.
