Full textAbstract:
(1) Background: The validation of hygiene procedures in food industries is paramount to ensure that food contact surfaces are properly decontaminated before production. Rapid, sensitive and reliable tools are needed for routine hygiene validation in order to increase food safety levels. Two novel tools for biofilm detection (TBF 300) and detection of low levels of microbial contamination (FreshCheck) have been assessed. (2) Methods: Biofilms of relevant food pathogens: Listeria monocytogenes and Salmonella spp. were grown for 3 and 10 days to assess the performance of the biofilm detection product. Surfaces were inoculated with different levels of L. monocytogenes to determine the limit of detection of FreshCheck. (3) Results: TBF 300 visibly stained 3 days-old biofilms of both pathogens, containing 5.0–5.4 log CFU/cm2. FreshCheck showed a positive reaction with contamination levels as low as 10 CFU/cm2 for L. monocytogenes. (4) Conclusions: Assessment of the hygienic status of food contact surfaces before production can be greatly improved with the use of the two novel tools evaluated in this study. The detection of microorganisms’ presence at very low levels of contamination as well as identification of biofilm growth spots is available in a rapid and easy way, with a big potential contribution to food safety.

Full textAbstract:
The sustainability debate in the food sector has exposed the current food system to critics, encouraging the significant growth of Alternative Food Networks (AFNs), new ways of food production, distribution and consumption that aim to shorten the food chain. Our study is focused on Food Assembly (FA), a special kind of AFN combining the culture of social entrepreneurship and digital innovation to achieve sustainability and a high social impact. The coexistence of a digital platform and a weekly farmers’ market triggers, within this network, mechanisms of knowledge sharing and self-organisation. To date, however, few studies have focused simultaneously on online and on-site interactions within AFNs, especially with quantitative studies. Our paper aims to test the hypothesis that online and on-site knowledge sharing affects the success of a FA measured by customer sustainable behaviour change. To do so, we developed a quantitative analysis based on a regression model. We collected data via a questionnaire submitted to 8497 Italian FA customers, of which 2115 responses were included in our analysis. The results show that online knowledge sharing significantly affects customer change towards more sustainable purchasing and consumption behaviours, while on-site knowledge sharing positively affects sustainable purchasing behaviours.

Full textAbstract:
Domestic wastewater reuse is currently not permitted anywhere in Australia but is widely supported by the community, promoted by researchers, and improvised by up to 20% of householders. Its widespread implementation will make an enormous contribution to the sustainability of water resources. Integrated with other strategies in the outdoor living environment of settlements in arid lands, great benefit will be derived. This paper describes six options for wastewater reuse under research by the Remote Area Developments Group (RADG) at Murdoch University and case studies are given where productive use is being made for revegetation and food production strategies at household and community scales. Pollution control techniques, public health precautions and maintenance requirements are described. The special case of remote Aboriginal communities is explained where prototype systems have been installed by RADG to generate windbreaks and orchards. New Australian design standards and draft guidelines for domestic greywater reuse produced by the Western Australian State government agencies for mainstream communities are evaluated. It is recommended that dry composting toilets be coupled with domestic greywater reuse and the various types available in Australia are described. For situations where only the flushing toilet will suffice the unique “wet composting” system can be used and this also is described. A vision for household and community-scale on-site application is presented.

Full textAbstract:
Waste management and production of clean and affordable energy are two main challenges that our societies face. Food waste (FW), in particular, can be used as a feedstock for the production of ethanol because of its composition which is rich in cellulose, hemicellulose and starch. However, the cost of the necessary enzymes used to convert FW to ethanol remains an obstacle. The on-site production of the necessary enzymes could be a possible solution. In the present study, the multienzyme production by the fungus Fusarium oxysporum F3 under solid state cultivation using different agroindustrial residues was explored. Maximum amylase, glucoamylase, endoglucanase, b-glucosidase, cellobiohydrolase, xylanase, b-xylosidase and total cellulase titers on wheat bran (WB) were 17.8, 0.1, 65.2, 27.4, 3.5, 221.5, 0.7, 0.052 and 1.5 U/g WB respectively. F. oxysporum was used for the hydrolysis of FW and the subsequent ethanol production. To boost ethanol production, mixed F. oxysporum and S. cerevisiae cultures were also used. Bioethanol production by F. oxysporum monoculture reached 16.3 g/L (productivity 0.17 g/L/h), while that of the mixed culture was 20.6 g/L (productivity 1.0 g/L/h). Supplementation of the mixed culture with glucoamylase resulted in 30.3 g/L ethanol with a volumetric productivity of 1.4 g/L/h.

ABSTRACT The intramolecular distribution of nitrogen isotopes in N2O is an emerging tool for defining the relative importance of microbial sources of this greenhouse gas. The application of intramolecular isotopic distributions to evaluate the origins of N2O, however, requires a foundation in laboratory experiments in which individual production pathways can be isolated. Here we evaluate the site preferences of N2O produced during hydroxylamine oxidation by ammonia oxidizers and by a methanotroph, ammonia oxidation by a nitrifier, nitrite reduction during nitrifier denitrification, and nitrate and nitrite reduction by denitrifiers. The site preferences produced during hydroxylamine oxidation were 33.5 ± 1.2‰, 32.5 ± 0.6‰, and 35.6 ± 1.4‰ for Nitrosomonas europaea, Nitrosospira multiformis, and Methylosinus trichosporium, respectively, indicating similar site preferences for methane and ammonia oxidizers. The site preference of N2O from ammonia oxidation by N. europaea (31.4 ± 4.2‰) was similar to that produced during hydroxylamine oxidation (33.5 ± 1.2‰) and distinct from that produced during nitrifier denitrification by N. multiformis (0.1 ± 1.7‰), indicating that isotopomers differentiate between nitrification and nitrifier denitrification. The site preferences of N2O produced during nitrite reduction by the denitrifiers Pseudomonas chlororaphis and Pseudomonas aureofaciens (−0.6 ± 1.9‰ and −0.5 ± 1.9‰, respectively) were similar to those during nitrate reduction (−0.5 ± 1.9‰ and −0.5 ± 0.6‰, respectively), indicating no influence of either substrate on site preference. Site preferences of ∼33‰ and ∼0‰ are characteristic of nitrification and denitrification, respectively, and provide a basis to quantitatively apportion N2O.

Full textAbstract:
Processes behind the shift from hunting-gathering to food production lifestyle are multifaceted and not yet completely understood. The Mediterranean coast of NW Africa provides an eclectic transitional pattern, namely, a very hesitant transition to food production. The distribution and abundance of early Neolithic domesticated species is disparate and region specific. Climate and environmental change have been often considered as an important influencing factor for this transition. This hypothesis was tested using archeological shells of the rocky intertidal gastropod Phorcus turbinatus recovered from the Ifri Oudadane site in NE Morocco. The oxygen isotope composition (δ18O) of the shell was used to examine whether the hesitant transition to food production was linked to a local climate shift in the Mediterranean Maghreb. Intrashell δ18O values suggest a marked temperature increase from >7.6 to ~7.0 cal. ka BP, the time when Neolithic innovations first appear on site. An additional increase in temperature from ~7.0 to <6.8 cal. ka BP matches with the beginning of the main occupation phase and the doubtless breakthrough of cultivation at Ifri Oudadane. This apparent warming trend, although considered preliminary, seems to match well with warming tendency observed in several published regional climate proxies. Therefore, a temperature shift may have played a role in the timing and implementation of food production in the area. Last growth episode δ18O values suggest that shellfish were harvested throughout most of the year, with noticeable intensification during the cooler half of the year. This preliminary pattern was fairly consistent throughout the Epipaleolithic and early Neolithic phases, pointing to a probable near year-round site occupation rather than a single season settlement. Future research on Ifri Oudadane and other NW African archeological records are much needed to assess whether these patterns persist in Morocco and other Epipaleolithic and early Neolithic settlements in the western Mediterranean Maghreb.

Full textAbstract:
The demand of modern societies for high food quality is evident. Thus, it is important for agriculture to produce row materials that are valuable for nutrition and have favourable characteristics for food processing. For this we need a knowledge about the factors which determine the quality of products. One of the main features of plant production is the “immobility”. This way the characteristics of the field influence the quality of the product, like example winter wheat, which is the main cereal in Hungary and Europe.The Concordia Co. has charged the Central Laboratory of Debrecen University, Agricultural Centre with laboratory testing of the 2002/2003 winter wheat crop. The samples consist of thirteen winter wheat varieties from six different sites under the same cultivating conditions. Therefore, the important wheat quality factors were analysed solely against site conditions with the use of Győri’s “Z” index, which contains these parameters.Soils were tested first. In this experiment excepting the negligible differences between the sites, there were no linear relations found between quality factors, productivity and soil features. The case is the same with the relation between precipitation, temperature and quality parameters. However, it must be noted that additional soil analyses are required to interpret the extreme results obtained from Karcag.The calculated Győri’s Z-index shows relative stability concerning certain varieties, although considerable deviation can be found in varieties related to the sites. According to these results, it can bestated that winter wheat quality was not linearly influenced by soil and weather in the 2002/2003 vegetation period. As the same cultivation technology was used in the experiment, the index was determined by genetic features. It must be noted that these findings are relevant only to this experiment.

Full textAbstract:
This short report presents results of excavation and analysis of a shell mound deposit at Mandjungaar, near Weipa, Cape York Peninsula. This study was initiated as a cultural heritage management project focused on a shell mound site damaged by unauthorised clearing of access tracks. This study included a small research component to establish a baseline understanding of longer-term use history of the Mandjungaar area at the request of Ndrua’angayth custodians. This included excavation and analysis of a test pit at the site. Results of the study are presented and contextualised in relation to previous research on the Weipa Peninsula in order to expand our understanding of the wider cultural history of the southern Weipa Peninsula. These results provide further support for the assertion that shell mound formation in the Albatross Bay region involved food production activities that were strategically focused on estuarine mud and sandflat ecosystems. In doing so, this dataset provides additional support for the previously proposed niche production model of shell mound formation.

Full textAbstract:
Food plays a central role in the production of culture and is likewise a powerful resource for the representation and organization of social order. Status is thus asserted or contested through both the materiality of food (i.e. its substance, its raw economics, and its manufacture or preparation) and through its discursivity (i.e. its marketing, staging, and the way it is depicted and discussed). This intersection of materiality and discursivity makes food an ideal site for examining the place of language in contemporary class formations, and for engaging cutting-edge debates in sociolinguistics and elsewhere on “language materiality.” In Elite Authenticity, Gwynne Mapes integrates theories of mediatization, materiality, and authenticity in order to explore the discursive production of elite status and class inequality in food discourse. Relying on a range of methodological approaches, Mapes examines restaurant reviews and articles published in the New York Times food section; a collection of Instagram posts from ©nytfood; ethnographically informed fieldwork in four renowned Brooklyn, New York, restaurants; and a recorded dinner conversation with six food enthusiasts. Across these varied genres of data, she demonstrates how a discourse of “elite authenticity” represents a particular surfacing of rhetorical maneuvers in which distinction is orchestrated, avowed/disavowed, and circulated. Elite Authenticity takes a multimodal critical discourse analysis approach, drawing on theories from linguistics, food and cultural studies, anthropology, sociology, and philosophy. Its presentation and analysis of aural, visual, spatial, material, and embodied discourse will be of interest to scholars and students of communication studies, critical discourse studies, sociolinguistics, linguistic anthropology, and cultural geography.

Full textAbstract:
AbstractRecirculating aquaculture systems, as part of aquaponic units, are effective in producing aquatic animals with a minimal water consumption through effective treatment stages. Nevertheless, the concentrated sludge produced after the solid filtration stage, comprising organic matter and valuable nutrients, is most often discarded. One of the latest developments in aquaponic technology aims to reduce this potential negative environmental impact and to increase the nutrient recycling by treating the sludge on-site. For this purpose, microbial aerobic and anaerobic treatments, dealt with either individually or in a combined approach, provide very promising opportunities to simultaneously reduce the organic waste as well as to recover valuable nutrients such as phosphorus. Anaerobic sludge treatments additionally offer the possibility of energy production since a by-product of this process is biogas, i.e. mainly methane. By applying these additional treatment steps in aquaponic units, the water and nutrient recycling efficiency is improved and the dependency on external fertiliser can be reduced, thereby enhancing the sustainability of the system in terms of resource utilisation. Overall, this can pave the way for the economic improvement of aquaponic systems because costs for waste disposal and fertiliser acquisition are decreased.

Full textAbstract:
AbstractThis chapter analyzes the impact of climate change and variability on food security of rural households in the central highlands of Ethiopia taking Basona Werana district as a case study site. Data were obtained from 123 households selected using simple random sampling from three agro ecological zones. Key informant interviews and focus group discussion (FDG) were used to supplement the data obtained from household survey. The monthly rainfall and temperature data are for 56 points of 10 × 10 km grids reconstructed from weather stations and meteorological satellite observations, which cover the period between 1983 and 2016. Standardized rainfall anomaly (SRA), linear regression (LR), and coefficient of variation (CV) are used to examine inter-annual and intra-annual variability of rainfall. Annual and seasonal rainfalls show decreasing trends over the period of observation. The decreasing trends in annual and March–May (Belg) rainfall totals exhibit statically significant decreasing trends at p = 0.05 level. Kiremt (June–September) shows statically significant decreasing trends at p = 0.1 level. Mean annual maximum and minimum temperatures show statically significant increasing trends at p = 0.05 level. More than 80% of households perceived that the climate is changing and their livelihoods (crop and livestock production) are impacted. The district belongs to one of the most vulnerable areas to climate change and variability in the country where large proportions of households (62%) are under different food insecurity classes. Results suggest that local level investigations are useful in developing context-specific climate change adaptation.

Full textAbstract:
AbstractAgriculture is the art and science of food production which spans soil cultivation, crop growing, and livestock rearing. Over the years, it has served as a means of employment and accounts for more than one-third of total gross domestic product. Cereals, which include rice, maize, and sorghum, are the major dietary energy suppliers and they provide significant amounts of protein, minerals (potassium and calcium), and vitamins (vitamin A and C). The growth and good yield of cereal crop can be greatly influenced by elements of weather and climate such as temperature, sunlight, and relative humidity. While climate determines the choice of what plant to cultivate and how to cultivate, it has been undoubtedly identified as one of the fundamental factors that determine both crop cultivation and livestock keeping. The chapter, though theoretical, adopted Kwara State, Nigeria, as the focus due to favorable weather conditions that support grains production. It was observed that the effect of climate change on cereal production includes: drastic reduction in grains production, reduction in farmers’ profit level, increment in cost during production, diversification to nonfarming activities, and discouragement of youth from participating in agricultural activities. Also, the adopted coping strategies employed by farmers in the focus site were early planting, planting of improved variety, irrigation activities, alternates crop rotation, and cultivation of more agricultural areas. The chapter thus concluded that climate change has negative impact on cereals production and recommends that government should provide communal irrigation facilities that will cushion the effect of low rains on farmers’ productivity, while early planting and cultivation of drought-resistant cultivars should be encouraged.

Throughout the colonial period, the occupants of the Betty’s Hope site relied a complex provisioning networks to obtain edible goods, tableware, and other necessities not only from the British Metropole and from local producers in Antigua but also from neighboring islands, including Guadeloupe, and from continental America. In this context, Betty’s Hope residents called upon food production and convivial hospitality were used to negotiate and stabilize their position within Antiguan society, both under slavery and after Emancipation (1834), under the particular constraints of absentee ownership and colonial trade regulations. The chapter combined the analysis of material cultural recovered at Betty’s Hope plantation with a close reading of correspondence relating to provisioning on the estate, to illustrate the enduring presence of informal trade, customary reciprocity, smuggling and illicit transactions on the estate throughout the nineteenth century.

Full textAbstract:
It is well established in the scientific community that agro-food wastes represent economic advantages and contribute to circular economy. For instance, wine industries of Região Demarcada do Douro involve the production of large quantities of by-products, such as stem, pomace, trimmed vine shoots, or wine lees, presenting a remarkable valuable composition in phytochemicals with putative health-promoting qualities. Nevertheless, the bioactive compounds obtained from these natural sources depends on the extraction process employed. In order to reduce production costs and optimize processes, new technologies—such as ultrasound-assisted extraction (UAE)—have been employed to decrease energy consumption and increase the product or process safety/control and quality. This work aims to characterize the phenolic compounds extracted from winery by-products (WBPs), namely grape stems, grape pomace, and wine lees of two grape (Vitis vinifera L.) varieties (Sousão and Tinta Barroca) from the same geographical site, as well as the antioxidant capacity. Wine lees and grape stems presented the highest concentration of phenolic compounds and the highest antioxidant capacity for Tinta Barroca variety, while grape pomace presented the highest values of these parameters for Sousão variety, demonstrating the high influence of the variety studied. Furthermore, wine lees revealed to be the winery by-product with the lowest antioxidant capacity and content of phenolics. These by-products revealed to be a rich source of phenolic compounds with high antioxidant capacities reveling to be of interest for pharmaceutical and cosmetic industries.

Full textAbstract:
Research indicates that individual consumers with food safety, environmental and ethical concerns regarding the provisioning of food may be motivated to use the marketplace as a site for political action to promote social change—a phenomenon known as political consumption (PC). Using data from Ohio 2007 Survey of Food, Farming and Environment, this research examined individual level attributes shaping engagement in PC and conventional political action. Findings based on logistic regression analyses, reveal that engagement in conventional political behavior is positively related to the likelihood of engagement in political consumption. This suggests that engagement in conventional political action and political consumption are not mutually exclusive. The main factors associated with engagement in political consumption are: knowledge about food production, environmental and food safety concerns. These findings suggest that consumers with concerns about the organization and character of food production believe they can create social changes via their consumptive decisions.

Chapter 6 discusses the Early Horizon, first millennium BC site of Samanco (450 to 150 cal BC), near the shore in the Nepeña valley on the north coast of Peru. Fishing and shellfishing were important, as was agriculture, with maize as the most important crop. Samanco was a food production center supplying inland polities with subsistence goods from the sea and from fields in the Nepeña delta. Trade in local, utilitarian goods was a defining feature of Samanco identity.

Houselot gardens are cultivated spaces located adjacent to households and are commonly used to grow flowers, herbs, vegetables, and fruits. They function as a primary source of a diverse array of food items, including staples, condiments, medicines, and spices; they provide non-food items as well, such as dyes, construction materials, or ornamental plants; and they provide a supply of food that is sold in local and extra-local markets. The diversity of plants and uses make gardens a fundamental element of household subsistence production. This chapter investigates the articulation of Maya gardening practices with economic systems, focusing specifically on how changes in the political economy affects household production. We utilize diachronic data from the Pre-Columbian Maya site of Chan, exploring how household gardening practices were affected in a dynamic political landscape from the Middle Preclassic to the Terminal Classic. These data are contrasted with synchronic data from the contemporary village of Lake Mensabak, a Lacandon Maya community going through rapid social and political disruptions. This chapter demonstrates that although houselot gardens are small-scale and household oriented, they reflect changes and upheavals in local, national, and international political economies.

Research work at the site of Canímar Abajo in northern Cuba, one of the rare Cuban sites investigated through systematic, large scale excavations, has yielded exciting new data that contribute to our understanding of two major themes in circum-Caribbean archaeology: 1. the timing of first migration to the Greater Antilles as well as the origins of the first settlers; and 2. the nature and timing of the origins of resource production in the Caribbean. The discovery of starch grains of maize (Zea mays), common bean (Phaseous sp.), sweet potato (Ipomoea batatas) and cassava (Manihot esculenta) in dental calculus from burials at this site have important implications for discussions on food production in the Neotropics. Research results indicate that a community of people practicing a subsistence regime of fishing, gathering, hunting and plant cultivation was already established in the area of the Canímar River estuary by 1200 BC. It is argued that the first migrants most likely crossed to the Greater Antilles from mainland Central America well before 1200 BC, and brought cultivated species originating in Mexico (maize and beans) and in Central America (sweet potato) with them.

<em>Abstract.</em>—Wood plays a major role in creating multiple invertebrate habitats in small streams and large rivers. In small streams, wood debris dams are instrumental in creating a step and pool profile of habitats, enhancing habitat heterogeneity, retaining organic matter, and changing current velocity. Beavers can convert sections of free-flowing streams into ponds and wetlands by killing trees and building dams. In low-gradient rivers, undercut trees that fall into the main channel (snags) are often the only stable habitat for invertebrates and provide a refuge and food resource for fishes as well. Invertebrates may use or require wood as food, but many species simply occupy wood as habitat. Although some species adapt to the woody environment by gouging and tunneling into the wood surface, others obtain their food from allochthonous and autochthonous resources that accumulate on the wood surfaces or are directly filtered from the water column. In streams of all sizes, accumulations of wood are often the hot spots of invertebrate diversity, and snags in Coastal Plain rivers of the southeastern United States support invertebrate production that is among the highest in lotic systems. The distribution of biomass and production among functional groups on wood varies greatly depending on the type of system. Loose streambed wood is colonized especially by shredders (gougers), and stable snags in larger streams and rivers are dominated by filterers and gatherers. High diversity of snag predators can result in complex food-web pathways, and snag taxa can be the major components of invertebrate drift in low-gradient rivers. Snag sampling is becoming a standard part of bioassessment, particularly in low-gradient systems, because snags are recognized as a major site of invertebrate diversity and production. Re-introduction of wood in streams and rivers is becoming an important aspect of restoration and management strategies around the world, as attempts are made to increase biodiversity and refuges both for fishes and their invertebrate prey.

Full textAbstract:
Many food processing plants in New York State generate large volume waste streams with a wide variety of physical and chemical properties. With greater environmental regulation and increasing fees for municipal sewer and solid waste disposal, additional innovative ‘disposal’ methods for these wastes need to be developed. One attractive alternative is to use the food processing waste as feedstock for a waste-to-energy conversion process comprising two distinct systems, namely waste-to-fuel and fuel-to-energy. The fuel can either be sold to generate revenue, or converted on-site to electrical or thermal energy to offset the plant power requirements. In this study, the technical viability and economic benefit of applying waste-to-energy solutions to a diverse selection of companies producing milk, cheese, beer, and tofu were assessed. Depending upon the volumes and composition of the available waste streams (including analysis of sugar content, biological oxygen demand, etc.) there may be a compelling business case to utilize the food waste as feedstock for ethanol, biodiesel or methane-rich biogas production.

Food is vital for human survival. Food has had a significant impact on our built environment since the beginning of human life. The process of feeding oneself was most people’s primary job for the greater part of human history. Urban Migration moved people away from rural and natural landscapes on which they had been dependent for food and other amenities for centuries.1 Emergence of the cities leads to a new paradigm where the consumers get their food from rural hinterland where the main production of food products happens2 . In a globalized world with an unprecedented on-going process of urbanization, There is an ever reducing clarity between urban and rural, the paper argues that the category of the urban & rural as a spatial and morphological descriptor has to be reformulated, calling for refreshing, innovating and formulating the way in which urban and rural resource flows happen. India is projected to be more than 50% urban by 2050 (currently 29%). The next phase of economic and social development will be focused on urbanization of its rural areas. This 50 %, which will impact millions of people, will not come from cities, but from the growth of rural towns and small cities. Urbanization is accelerated through Government schemes such as JNNURM (Jawaharlal Nehru National Urban Renewal Mission ) , PMAY (Pradhan Mantri Awas Yojana), 100 smart cities challenge, Rurban Mission are formulated with developmental mindset. The current notions of ‘development’ are increasing travel distances, fuels consumption, food imports, deterioration of biodiversity, pollution, temperatures, cost of living. The enormity of the issue is realized when the cumulative effect of all cities is addressed. Urban biased development becomes an ignorant choice, causing the death of rural and deterioration of ecological assets. Most people live in places that are distant from production fields have been observed as an increasing trend. Physical separation of people from food production has resulted in a degree of indifference about where and how food is produced, making food a de-contextualized market product as said by Halweil, 20023 . The resulting Psychological separation of people from the food supply and the impacts this may have on long term sustainability of food systems. Methodology : . Sharing the learning about planning for food security through Field surveys, secondary and tertiary sources. Based on the study following parameters : 1. Regional system of water 2. Landforms 3. Soil type 4. Transportation networks 5. Historical evolution 6.

Full textAbstract:
Climate change together with increasing demand for space pose a challenge to energy and food production at sea areas. Co-location of offshore renewable energy production, aquaculture and other blue economy activities can answer the need for more sustainable marine space utilization while reducing and dividing costs of the different activities. This paper presents a case study of a multi-use platform that combines wind energy and fish farming in the Gulf of Bothnia, where the sea freezes every winter. A marine spatial planning (MSP) tool is used to find suitable locations for the multi-use platform with respect to economic potential of energy and nutrient production, structural solutions and environmental impact. The tool is used to visualize site selection criteria based on geographic information system (GIS) data such as seabed data, wind and wave data and ice data as well as protected marine areas. Production potential scenarios for the multi-use platform at different scales are calculated. Synergies of combining offshore wind energy and fish farming are discussed.

Full textAbstract:
In the food industry, there is typically a requirement for electric power, process steam as well as cooling capability. Based on actual requirements of a specific site, a study was performed to define two different Combined Heat and Power (CHP) options and to compare them over a one year period regarding the extent to which they satisfy the operator’s needs. CHP is defined as the sequential generation of two different forms of usable energy from a single fuel source. It is mechanical energy and thermal energy. The mechanical energy may be used either to drive a generator to produce electricity, or to drive rotating equipment such as a compressor. Thermal energy can be used either directly for process applications or indirectly to produce steam, hot water (district heating), or chilled water for cooling purposes. Combined Heat and Power technologies are proven, reliable and cost-effective. MAN can offer different CHP concepts adapted to specific customer requirements. This paper presents the results of a comparative study based on the typical requirements of the food industry. The CHP system has to cover the demand for power, saturated steam at two pressure levels, and cooling. Two different CHP options were studied and compared regarding technical and economic considerations. The first system proposed is based on a MAN’s gas turbine (model: THM1304-10N) in the 10 MW class, a Waste Heat Recovery Unit for steam production and one Absorption Chiller (ammonia/water) for cooling process. A share of the steam produced is used for driving the chiller. The second system includes a combined cycle with MAN’s new MGT6100 gas turbine in the 6 MW class. A Waste Heat Recovery Unit and a back pressure steam turbine with two extractions at two intermediate pressure levels are used. A part of the saturated steam at the outlet of the steam turbine drives the absorption chiller and the remainder is used for the third steam process. For both options, a supplementary firing is also considered. A technical and economical comparison between the two solutions is provided in order to show the advantages and the disadvantages of each system with regard to the requirements of the specified application.

Full textAbstract:
Agrarian sector occupies a special place in the structure of the economy. The article presents the characteristics of this segment and its infrastructure in Ukraine. The transition to a market economy requires the formation of an appropriate market environment, without which the civilized market and agrarian, in the first place, cannot work normally. Agrarian producers independently choose channels for selling their products, forms of sales and sales of resources and use various intermediary structures in their economic activities. All these activities lead to the need to collect, accumulate and process growing information streams that farms have to use efficiently and in a timely manner. The harmonious development of the entire system of social production and food security of the country depends on the effective functioning of all available infrastructure components. Based on the foregoing, it is possible to understand that this topic is extremely important and require the research. The goal of the article is to investigate the condition of the agricultural market and its infrastructure in Ukraine. It was described the main problems of agriculture. To make the research about the topic, it was necessary to use data from the official site of State Statistic Service of Ukraine. It was analyzed the project Strategy for the development of the agrarian sector in Ukrainian economy for the period up to 2020. This project is developed by the Ministry of Agrarian Policy and Food of Ukraine. Also, it was needful to use synthesis, analysis, deduction, induction, and comparison methods. As a result of research, we described possible ways to resolve main problems in this sphere, made the analysis of the main statistical data which are related to the agrarian sector.

Full textAbstract:
Honeycomb sandwich panels are widely used for high performance parts subject to bending loads, but their manufacturing costs remain high. In particular, for parts with non-flat, non-uniform geometry, honeycombs must be machined or thermoformed with great care and expense. The ability to produce shaped honeycombs would allow sandwich panels to replace monolithic parts in a number of high performance, space-constrained applications, while also providing new areas of research for structural optimization, distributed sensing and actuation, and on-site production of infrastructure. Previous work has shown methods of directly producing shaped honeycombs by cutting and folding flat sheets of material. This research extends these methods by demonstrating work towards a continuous process for the cutting and folding steps of this process. An algorithm for producing a manufacturable cut-and-fold pattern from a three-dimensional volume is designed, and a machine for automatically performing the required cutting and parallel folding is proposed and prototyped. The accuracy of the creases placed by this machine is characterized and the impact of creasing order is demonstrated. Finally, a prototype part is produced and future work is sketched towards full process automation.

"The paper concerns the logistics activities related to perishable products. Perishable products are delivered from the production site to a warehouse by refrigerated truck. Perishable products are accepted or not at the warehouse entrance, according to their detected quality levels; if accepted, they are stored in the warehouse in suitable environmental conditions. Finally, they are delivered by refrigerated truck to the destination. Human errors affect these activities. Perishable products have to be delivered in a suitable quality level to the destination. Because of human errors, sometime products arrive in an unsuitable quality level and therefore, there is a loss for the company. RFID technologies, integrated with time temperature indicators (TTI), allow a prompt detection of abnormal quality loss and the prompt actuation of mitigation actions. In order to evaluate the benefits of different RFID-TTI implementation set-ups, the study defines a methodology that measures the risk of monetary losses. The method is applied to a case study and the results are presented."
