The dimension stone sector is more and more active in developing new solutions to improve the sustainability of its supply chain, partly as a consequence of the current EU policies on Circular Economy and Raw Materials. The Life Cycle Assessment (LCA) is a recognized scientific tool for evaluating environmental impacts of the processes. Nevertheless, in the stone sector, LCA is hindered by the scarce availability of Life Cycle Inventory (LCI) datasets for the specific processes of the stone supply chain. This paper provides LCI datasets of the most common and widespread techniques and related technologies for quarrying, cutting and finishing soft-weak stones. To this aim primary data were collected in Italian marble quarries and processing plants and in companies producing cutting tools. When necessary, industry data were complemented with secondary data from literature. High replicability and flexibility of the datasets is obtained through the provision of Unit process inventories for each technology/technique and through the set of parameters. In addition, the uncertainty of the resulting LCI datasets has been evaluated with the well-established procedure of Ecoinvent pedigree matrix. The availability of these datasets contributes to the population of Life Cycle databases and is expected to boost the measurement and enhancement of the key aspects of sustainability in the stone sector.

Life-cycle assessment (LCA) is increasingly used to quantify the environmental impacts of construction materials. However, the relationship between the durability and LCA of these complex products with long life-cycles must be analysed in detail, namely using stochastic data from service life prediction (SLP) studies. However, SLP uncertainty is not yet considered in LCA, thus resulting in insufficiently sound decisions at the design stage. This paper presents the modelling of the uncertainty of SLP using advanced statistical methods and its application in the estimation of SL and corresponding number of replacements of claddings (renderings and stone claddings). These results are used in an interdisciplinary study of SLP and LCA to apply in the stochastic comparison of the LCA of claddings. This methodology aids in the choice of the option with better environmental performance right at the design stage, via the comparison of their standard, deterministic and stochastic LCA results.

Precision agriculture is a concept that encompasses various technologies aimed at optimizing the management of agricultural activities. The main aim of this investigation is to evaluate the environmental and economic performance of precision agriculture practices on the production of a stone fruit crop (nectarine) using a life cycle approach and to consider a cradle-to-farm gate scope. The results have been compared against the traditional uniform application (UA). The analysis considers five impact categories, including climate change, photochemical ozone formation, acidification, eutrophication, and water use. The foreground inventory data was provided by a local producer in Southern Spain, and the background information was sourced from commercial Life Cycle Inventory (LCI) databases. The results show that the manufacturing of crop inputs (mainly fertilizers, but also crop management inputs) is responsible for most of the damage generated in all the impact categories, except for water use. The reduced input requirements associated with the application of VA techniques resulted in significantly lower economic costs and environmental savings throughout the life cycle of the production system, which ranged on average between 12–26%.

Abstract Ceramic bricks are among the most used building material throughout human history for their excellent technical properties, abundance of raw materials and easy production. Huge quantity of brick waste is generated from demolition works at the end-of-life stage of buildings. Several scenarios within waste management hierarchy can be considered: a) preparing for reuse of bricks into masonry units for similar purposes; b) mechanical recycling (crushing, screening) to crushed stone for various applications -in backfilling, pavement, drainage works, which are examples of down-cycling or as concrete aggregate and as a component in blended binders which are examples of upcycling; c) disposal at inert waste landfills or used as a separation layer at municipal waste landfills. This study performs a life cycle assessment (LCA) of these three possible routes for ceramic waste and takes into account the relevant processes. The LCA results are calculated for the compulsory environmental indicators according to the methodology of EN 15804 along with the additional indicators assessing toxicity. The outcome of the LCA confirms that the most environmentally beneficial scenario is the reuse of bricks as it requires minimal activities for preparing. Technical feasibility issues and costs impact, associated to the three scenarios are also analysed. The conclusion is that an optimised and sustainable approach of bricks end-of-life shall be applied in order to boost the circularity in construction sector.

The manufacturing and construction industries have always been large contributors to global CO2 emissions, largely as a consequence of material choices. Two of the most commonly used building materials are concrete and steel, but both of these industries have been identified as large sources of atmospheric CO2. Therefore, reducing the use of these materials and finding alternatives to them that meet the engineering requirements of a design, while also minimizing emissions, is becoming increasingly important. Stone in its natural form is a zero-carbon emission material and has strong physical properties that make it a viable substitute for concrete and steel, across a range of applications. Yet research into the potential use of stone by the construction industry remains rare. The aim of this research is to investigate whether the use of stone as a building product is a feasible alternative in terms of carbon emissions. This study compares data from 11 Environmental Product Declarations (EPDs) that provide Life Cycle Analysis (LCA) assessments of their considered product (i.e., types of dimensional stone, concrete, or steel). However, this research also highlights some shortcomings in the EPDs that point to a need for greater legitimate engagement with this tool, and for more consistency between the data being presented in EPDs. Global Warming Potential (GWP) data are compared between products to determine the difference in carbon emissions. The results indicate that GWP values for dimensional structural stone (135 kg.CO2/m3) are 45–75% lower than the concrete products considered in this investigation (246–514 kg.CO2/m3), and over 99% lower than certain steel products (22,294–29,202 kg.CO2/m3). This research indicates that stone is demonstrably better in terms of its GWP, and that a more extensive use of structural stone represents a key opportunity for the construction industry to reduce its CO2 emissions.

This study aimed to analyze the major building materials in terms of environmental impact evaluation of school buildings in South Korea. Three existing school buildings were selected as the analysis targets, and building materials were analyzed in terms of cumulative weight and six environmental impact categories (global warming potential, abiotic depletion potential, acidification potential, eutrophication potential, ozone-layer depletion potential, and photochemical oxidation potential). The materials were analyzed from an environmental perspective after integrating the six environmental impact categories into the environmental costs. From the analysis, nine major building materials, including ready-mixed concrete, concrete bricks, aggregate, rebar, cement, stone, glass, insulating materials, and wood, were selected for the school buildings. These analysis results can be used as a streamlined evaluation of the environmental impacts of school buildings. It is thought that the simplified life cycle assessment will help make decisions considering environmental characteristics in the early stage of the construction project. Additionally, it will be possible to make LCA efficient in terms of time and cost, one of the largest constraints of the existing building LCA, and effective reduction in the environmental load.

The main objective of this paper thesis is to determine the environmental impact of two houses made of two alternative materials - a wooden and a brick house - using a Life Cycle Assessment (LCA). By comparing the material composition of their design to determine the environmental impacts of global warming, human health, consumption of resources and ecosystem quality. An overall comparison showed that the materials for the construction of a wooden house have less negative impact on the environment than materials for the construction of a brick house. Using the GWP method, results show that the materials for the construction of a brick house leave twice the carbon footprint in the environment than materials for a wooden house. This resultant state is mainly due to the use of natural materials in the wooden house (wood, fibre insulation), unlike the materials used in the brick house (ceramic masonry, insulation from stone wool) and so on.

Modelling the behaviour of extinct hominins is essential in order to devise useful hypotheses of our species' evolutionary origins for testing in the palaeontological and archaeological records. One approach is to model the last common ancestor (LCA) of living apes and humans, based on current ethological and ecological knowledge of our closest living relations. Such referential modelling is based on rigorous, ongoing field studies of the chimpanzee ( Pan troglodytes ) and the bonobo ( Pan paniscus ). This paper reviews recent findings from nature, focusing on those with direct implications for hominin evolution, e.g. apes, using elementary technology to access basic resources such as food and water, or sheltering in caves or bathing as thermoregulatory adaptations. I give preference to studies that directly address key issues, such as whether stone artefacts are detectible before the Oldowan, based on the percussive technology of hammer and anvil use by living apes. Detailed comparative studies of chimpanzees living in varied habitats, from rainforest to savannah, reveal that some behavioural patterns are universal (e.g. shelter construction), while others show marked (e.g. extractive foraging) or nuanced (e.g. courtship) cross-populational variation. These findings allow us to distinguish between retained, primitive traits of the LCA versus derived ones in the human lineage.

The main goal of the PhD research project is to contribute to the development of methodologies and Life Cycle Inventory data of the most representative techniques and technologies in the ornamental stone supply chain. The realisation of Life Cycle datasets, currently scarcely available in Life Cycle databases, aims to provide a practical tool to enterprises and researchers dealing with sustainability issues in the stone sector. The interest in enhancing the stone supply chain sustainability has been boosted by the recent European policies on Circular Economy and Raw materials, which are encouraging the passage from a linear economy (made of the phases of extraction-production-use-disposal) to a circular economy, where the value of products, materials and resources is maintained in the economy for as long as possible (European Commission, 2015). Moreover, sustainable supply chain improvements are urged by the market competition, represented by stone materials from developing countries and by other Italian construction materials, whose sectors have started thinking in terms of sustainability from quite a long time, gaining a priority with, for examples, Green Public Procurements. In this context, the Life Cycle Assessment (LCA) has been identified as the best framework for assessing the potential environmental impacts of products by the European Commission’s Integrated Product Policy Communication (COM (2003) 302). LCA is indeed a scientific and standardized tool which considers the entire life cycle of a product/process in order to quantify materials, energy and emissions and to evaluate the environmental consequences. Nevertheless, in the stone sector, LCA is hindered by the current scarce availability of Life Cycle Inventory datasets on the specific stone supply chain techniques and technologies. In this context, the PhD project here presented gives a contribute to fill the gap in LCI datasets availability and quality. To this aim primary data were collected in Italian quarries, transformation plants and cutting tool enterprises (in particular, 4 marble quarries, 10 gneiss quarries, 7 transformation plants and 3 tool producers). When necessary, secondary data (from papers, patents and technical sheets) were also collected to complete the inventory or to cross-check the measured data. On the basis of these data, the average datasets of the stone supply chain techniques were modelled using Gabi software. Finally, primary data uncertainty on the collected data was handed through the calculation of the standard deviation, to assess the value ranges around the mean values and to evaluate the consequent precision of the LCI datasets. The modelled LCI datasets have been also submitted to an internal quality control based on impact assessment results. Uncertainty analyses have been developed through the calculation of standard deviation on some impact results and through Monte Carlo stochastic simulations (run with 1000 iterations), which evaluate the stability of the results toward random parameters constellations. In addition, the developed LCI datasets on stone technologies have been organised in a cradle-to-gate LCA model which, through editable parameters, can be easily adapted to perform LCA of specific stone supply chains. It has been created a unique model comprehending technologies for both soft and hard stones, in order to allow the model to be employed also by enterprises working with both the materials in the same plant. Finally, a collaboration with the Brazilian CETEM research centre, led to the development of a preliminary study on Social Life Cycle Assessment (SLCA). Following the UNEP/SETAC guidelines on SLCA (2009), secondary data have been collected for both the Italian and the Brazilian ornamental stone sectors. Questionnaires to collect primary data are proposed with the aim of supporting future works on stone social sustainability. This PhD study is therefore expected to boost to use of the LCA tools among stone enterprises and to provide data able to support researchers and decision makers.

Since the LCD TV product has the exclusive innovation function and the high price attribute, the consumer must be educated to accept the specialized knowledge of digital electrical products urgently. The traditional consumer behavior theory which based on brand does not apply well the innovated electronic product selecting and purchasing, and since the emergence of the experience economy, it is helpful for consumer's purchase decision-making by providing the consumer the chance to experience the real store environment. This research takes product attribute, product brand knowledge and store environment as variables and explores the influence of perceived quality, perceived risk and perceived value on the consumer’s purchase intention. This research takes LCD TV as the research object, conducting the questionnaire survey in convenience sampling way in view of the consumers who have the actual purchase experience or purchase intention for LCD TV. 550 copies of questionnaire were distributed; 523 copies returned and the returns-ratio is 95.1 %. The research employs the regression analysis in order to find the relations within the product attribute, product brand knowledge, store environment, perceived quality, perceived risk and perceived value, and also their affects on consumer's purchase intention. The findings of this research are that, (1) the product attribute has influence on perceived quality and perceived risk. If the product attribute is better, the consumer feels higher perceived value, which will enhance the consumer's purchase intention. (2) the product brand knowledge does not have direct influence to perceived risk. In other words, the consumer still worries about exclusive innovation function and high price and is unable to reduce perceived risk and enhanced perceived value of the products. (3) the atmosphere factor of store environment does not reveal influence on perceived risk, but social factor and design factor do affect perceived quality and perceived risk, and the consumer has higher perceived value feelings. This research provided the following managerial proposals to the management of the industrial field based on the conclusions of this study, (1) strengthens the product function to increase the consumer perceived value. (2) strengthens the advertisement and the marketing innovation and makes the fine brand to increase the customer value. (3) establishes the fine store environment positively, creates consumer's percetived value.

AbstractThe stone industry plays an important economic role in Italy as well as worldwide, and its products are part of the construction sector for hard coverings. The relevance of these products led the European Commission to develop specific criteria for natural stone within the Ecolabel scheme for hard coverings. In order to provide environmental information and to establish and maintain their comparability, the eco-labelling schemes recognized the life cycle assessment (LCA) as a scientific method to be employed when describing the environmental performance of the products. In its current form, the European Ecolabel scheme only considers environmental impacts and overlooks significant social impacts, especially for the category of stakeholders most affected during the extraction and manufacturing phases: workers. The main purpose of this study is to define a set of social criteria to be added to the revised version of the European Ecolabel with reference to issues concerning natural stone covering products. In particular, according to the updated guidelines for the social life cycle assessment by UNEP/SETAC Life Cycle Initiative (2019), we have identified that the “health and safety” impact category as it relates to workers during the extraction and manufacturing phases of the products must be considered a priority. The results provide a set of criteria for the S-LCA inventory which should be added to the Ecolabel guidelines when assessing the natural stone covering sector. Integration of the social sphere with the results obtained from the LCA study would provide reliable and more complete information on the sustainability of the natural stone product.This represents a first step towards the inclusion of similar criteria for other covering products.

AbstractCompanies awareness of the impact generated by its products increases and motivates them to develop initiatives to improve their sustainability. In this work, a methodology consisting of three main phases: sustainability assessment, redesign process and comparison of designs, is proposed to obtain more sustainable product designs. Methodology is based on the Life Cycle Sustainability Assessment (LCSA) approach, which is applied to simultaneously evaluate environmental, economic and social aspects. In the case study the sustainability improvement of the furniture of a clothing retail store is addressed. A set of indicators are considered to evaluate the sustainability performance of both initial design and redesign. The study concludes that the application of different sustainability strategies allows a significant enhancement of the environmental and economic indicators.

Wherein resides the ‘art’ in the ‘art of building’? Throughout history, architects have generally viewed their field as a craft informed by the human body, a creative sense of play, and technical science. Theory in the second half of the 20 th century departed from this direction by reducing art to the visual and semiotic understanding of form. The remarkable discoveries of the biological sciences in recent decades have opened an entirely new perspective for designers, based on our profound insights into human soci-ality, empathy, emotion, mirror systems, and design’s inherent powers of “tactility and kinesis.” The dictum “know thyself,” once inscribed in stone at the entrance of the Temple of Apollo at Delphi, in many ways holds the key to locating the missing ‘art’ of design.

The consumption of fabrics in 18th-Century Europe experienced a notable expansion - particularly in France, a major hub for the diffusion of clothing fashions across the continent. Driven by manufacturers and merchants, the supply of new product varieties has been highlighted in several French production areas. However, a general assessment of the scale and rates of product innovation in the market for fabrics has never been attempted. By varying the scales of analysis, from the statistics the French monarchy used to assess production in the various production areas to store inventories, we can try to estimate the secular movements of product innovation. Over the course of the 18th century, the market for medium or poor quality cloths appears to have been particularly dynamic: the proportion of new varieties at the end of the century approximated two-thirds of the stock. There was also a tendency to diversify the supply - which ended up making the "world of goods" difficult to read, many product innovations being present on the market only for a while.

On November 2, 1966, the Experience record Jimi’s newly composed “Stone Free” during a single session at De Lane Lea Studios. Chas Chandler arranges a record deal with Track Records and Jimi begins work on his ambitious “Third Stone from the Sun,” inspired by his love of science fiction. Chandler, Jimi’s father James “Al” Hendrix, and best friend Billy Cox describe his extraordinary all-day, every-day dedication to the guitar. Kathy Etchingham details their home life together and forays around London. During a tour of Germany, Jimi accidentally smashes a guitar and discovers “demolition feedback.” The Experience’s London afternoon showcase at the Bag O’Nails is attended by Jimmy Page, Eric Clapton, members of the Beatles and Rolling Stones, and leading British music journalists, whose write-ups contribute to Jimi’s rapid ascent to fame. Meanwhile, his unprecedented guitarmanship and sexually-suggestive stage moves frighten The Who’s Pete Townshend and other leading British guitar icons.

Cooking is one of the most important final household uses of energy. In Ecuador, the main energy carrier for this use is liquefied petroleum gas (LPG), which normally is supplied in bottles. LPG is imported and heavily subsidized for household consumption. The Government has promoted the use of electric induction stoves provided the hydropower generation capacity in Ecuador is projected to grow. Sustainability issues should be considered when changes in energy systems are analyzed. Life cycle assessment (LCA) is a methodological framework that can be used to quantify the environmental performance of any product or service, including energy systems. LCA can be used to quantify a range of environmental impact categories including Climate Change. The life cycle greenhouse gas emissions of a product or service are also known as carbon footprint. The objective of this study is to quantify the change in the carbon footprint of the household cooking system from the current based on LPG to the proposed based on electricity, and the cumulative energy demand (CED) for cooking with both technologies, using the LCA methodology, in order to provide a basis for the development of policies to reach the maximum mitigation of greenhouse gases (GHG). Several scenarios that consider different electricity generation mixes, cooking efficiency and emissions profile are studied. The functional unit for comparison was defined as “1 effective MJ”, which is 1 MJ transferred to the food during cooking. System boundaries for the assessment included resources extraction, processing, energy carrier supply, cooking and manufacturing of the stove. The results depend highly on the carbon footprint of the electricity system and, in a lesser extent, on the stove efficiency. Main results indicate that a carbon footprint mitigation occurs when changing the conventional LPG to a highly hydropower based cooking system, and that a higher life cycle energy efficiency is obtained when a high stove efficiency is considered. However, a greater carbon footprint may occur when cooking is performed using fossil derived power, which is a possible case when cooking is performed during peak demand of electricity.

Scattered throughout the Great Basin and the drainages of the upper Colorado and Rio Grande Rivers is a legacy of prehistoric and historic (i.e., post-Spanish contact) Indian rock art that represents a several-thousand year old tradition of creating culturally meaningful images on stone. Depending on the nature of the stone surface, and also on the intent of the "artist", the images were either pecked, scratched or abraded into the stone, or painted on suitably smooth and protected cliff walls. The terms petroglyph and pictograph are respectively applied to these two basic techniques. Petroglyphs typically were pecked through the dark patina coating, which slowly develops on many rock surfaces in the desert environment, to disclose the lighter colored rock beneath, whereas mineral-based pigments were employed in making pictographs. Among the inventory of images are human-like (anthropomorphic) and animal (zoomorphic) forms, as well as a large variety of abstract elements and more esoteric designs that are subject to various interpretations. With time, the rock art of the Great Basin area generally evolved from the abstract to the more representational, although many abstract designs remained popular (i.e., meaningful) throughout the area's long history.

Abstract Constructed wetlands (CW) are man-made systems that mimic the natural wetlands. They can be used for various purposes, including wastewater treatment, stormwater management, and carbon sequestration. Wetlands naturally absorb and store carbon from the atmosphere, and CW can replicate this process by using plants and microorganisms to remove and store carbon from the water. Conventional wastewater treatment plants (WWTP) use more energy and contribute to carbon emissions, so many industries are looking for ways to reduce greenhouse gas (GHG) emissions. While CW have been widely used for municipal and sewage treatment, their use as an alternative or supplement to industrial wastewater treatment, particularly in the oil and gas and petrochemical industries, is limited. However, CW have the potential to promote carbon sequestration and have a lower cost of capital and operating expenses compared to conventional WWTP, while also emitting lower GHG emissions. A case study is presented for two types of system in which one is actual operating conventional WWTP in Malaysia design and operate at 60m3/d and a hybrid CW of equivalent treatment capability and capacity. The case study found that GHG emissions from a conventional WWTP were approximately 3.75 times higher than the hybrid CW system with the same treatment capacity. For a small capacity WWTP at 60m3 per day, converting the treatment system from conventional WWTP to CW will reduce approximately 45.7t CO2 eq per year based on Life Cycle Assessment (LCA) calculation. The conventional WWTP consumed much higher power especially from the air blower compared to CW where limited number of equipment is required. The additional carbon sink for CW from carbon sequestration from plant, soil decomposition and sediment has not been quantified in the LCA calculation. Hence, it is expected the actual CO2 eq emission for CW is much lesser than the conventional WWTP. With all the benefit identified and the proven success case in several places, the adoption of CW as an industrial WWTP should be widely promoted as the replacement of conventional WWTP for sustainable future.

Hempcrete is a natural building material obtained mixing hemp shives (i.e., the woody core of the hemp plant) with a lime-based binder and water. Hempcrete as construction material is gaining increasing interest as the EU aims to achieve net zero emissions by 2050. This material has, in fact, the ability to uptake carbon dioxide from air (i.e., via carbonation) and to store carbon for long time. The goal of the present work is to deeper analyze the environmental profile of hempcrete, in order to assess its potentials in reducing emissions of construction sector. Specifically, Life Cycle Assessment (LCA) of a non-load-bearing wall made of hempcrete blocks is carried on. The analysis encompasses the whole life cycle from the extraction of raw materials to the end of the service life. The analyzed blocks are produced by an Italian company. Only aerial lime is used as binder, microorganisms are added to the blocks to accelerate carbonation. The impact on climate change is assessed through the GWP 100 method proposed by IPCC. Preliminary results reveal a nearly neutral carbon budget.

CSP plants using supercritical CO2 (sCO2) power cycle can potentially achieve high thermal conversion efficiency at low capital cost due to compact turbomachinery and other components. An sCO2 expander and improved heat exchanger is expected to provide a major stepping stone for achieving CSP power at $0.06/kW-hr LCOE, energy conversion efficiency > 50%, and total power block cost < $1,200/kW installed. However the life limiting mechanisms of these turbomachines in high pressure, high temperature sCO2 environment are not well understood. To understand the effect of high pressures, high temperatures and sCO2 chemical kinetics on crack initiation, crack propagation and low cycle fatigue (LCF) life of these turbomachines, a novel experimental setup is developed. Advanced microstructure and spectroscopic analyses are conducted that shed light on some key differences between various Ni base alloys in terms of oxidation morphology, chemical species diffusion and trapping, the formation of protective corrosion resistant layers and changes in surface properties. An experimental technique for low cycle fatigue experiments in high pressure, high temperature supercritical CO2 environment is developed. The test setup allows for pressurized LCF testing of alloys being considered for MW scale sCO2 turbine development. Results show that the LCF life remains the same (within the scatter band) irrespective of the location of crack initiation site whether at the OD (non shot-peened bars in air and sCO2), or at the ID (shot peened bars). Total fatigue life, for all conditions, lie within the normal variation in LCF results (± 2X life variation). No significant LCF life debit is observed in IN718 by sCO2 at 550 °C, 0.7% max strain, 20 cpm. Similar conclusion is reached during 0.6% max strain tests. The effect of sCO2 is found not to be significantly more damaging than air at these strain levels. However, the results can be different for lower % max strains due to longer exposure times involved, resulting from larger number of cycles to failure. Similarly at higher temperatures and/or longer hold-times, sCO2 environment may be more aggressive, resulting in lower total fatigue life.

În jumătatea a doua a secolului al XIX-lea apar primele romane românești, care, deşi inegale ca realizare, reprezintă un document al vremii şi furnizează şi astăzi informaţii preţioase privind circulaţia, semnificaţia şi forma unor cuvinte. În lucrare se analizează stratul lexical al romanului Ciocoii vechi și noi de Nicolae Filimon. Stăpânirea fanariotă din Moldova și Țara Românească și-a lăsat amprenta nu numai sub aspect social și moral, ci și lexical. Atmosfera romanului este țesută în majoritate din cuvinte de origine turcă și neogreacă, specifice epocii descrise. Acestea denumesc funcții, ranguri și ocupații, instituții, piese de vestimentație, stofe, feluri de mâncare, calități și defecte umane ș.a., constituind o radiografie a epocii sub aspect etimologic.

In this article, the author considers various aspects of teaching Chinese in Russia, and also specifies some factors that affect the successful mastery of the Chinese language, in particular, learning in a natural language environment as a part of student exchange programs, during which students study language material in class with native speaker and have the opportunity of extensive language practice outside the school. In addition, the author notes the importance of the sociocultural component in learning - familiarity with the traditions and holidays of China, thereby increasing students' interest in the culture of the country of the language being studied. The article also notes the difficulties that both students and the teacher encounter in the classroom at North-Eastern State University, caused by the fact that in the same group are both students who have undergone language training in China and those who have not yet had a chance to study there. This is manifested in different levels of language proficiency by students, primarily in the level of their oral speech skills. This situation affects the group's learning speed and requires the teacher, in turn, to have a differentiated approach to conducting classes. The author suggests maximizing the practice of students using the Chinese language - conducting classes in the language they are studying, stimulating them to communicate only in Chinese within the class, and also, if possible, beyond. The basis of this practice is proposed to put thematic-situational training, for example, within the framework of the topic “Shopping”, interactively consider situations “in a clothing store”, “in a mobile phone store”, etc. At the same time, the author notes that the same situations proposed in the educational literature are perceived differently by native speakers and students, since they are filled with realities characteristic of China and different from the usual realities of Russia. To familiarize students with similar sociocultural content, it is proposed to use multimedia teaching aids - video and graphic presentations.

Monilinia fructicola causes brown rot blossom blight and fruit rot in stone fruits. Immature fruit are highly resistant to brown rot but can become infected. These infections typically remain superficial and quiescent until they become active upon maturation of the fruit. High levels of chlorogenic acid (CGA) and related compounds occur in the peel of immature fruit but these levels decline during ripening. CGA inhibits cutinase expression, a putative virulence factor, with little or no effect on spore germination or hyphal growth. To better understand the regulation of cutinase expression by fruit phenolics, we examined the effect of CGA, caffeic acid (CA) and related compounds on the redox potential of the growth medium and intracellular glutathione (GSH) levels. The presence of CA in the medium initially lowered the electrochemical redox potential of the medium, increased GSH levels and inhibited cutinase expression. Conidia germinated in the presence of CA, CGA, or GSH produced fewer appressoria and had elongated germ tubes compared to the controls. These results suggest that host redox compounds can regulate fungal infectivity. In order to genetically manipulate this fungus, a transformation system using Agrobacterium was developed. The binary transformation vector, pPTGFPH, was constructed from the plasmid pCT74, carrying green fluorescent protein (GFP) driven by the ToxA promoter of Pyrenophora tritici-repentis and hygromycin B phosphotransferase (hph) under control of the trpC promoter of from Aspergillus nidulans, and the binary vector pCB403.2, carrying neomycin phosphotransferase (nptII) between the T-DNA borders. Macroconidia of M. fructicola were coincubated with A. tumefaciens strain LBA 4404(pPTGFPH) on media containing acetosyringone for two days. Hygromycin- and G418-resistant M. fructicola transformants were selected while inhibiting A. tumefaciens with cefotaxime. Transformants expressing GFP fluoresced brightly, and were formed with high efficiency and frequency of T-DNA integration frequency. The use of these transformants for in situ studies on stone fruit tissues is discussed.
