Food tourism challenges in the pandemic period: getting back to traditional and natural-based products

ABSTRACT Searching for rural, intact areas out of cities during the COVID-19 crisis, tourists brought renewed interest in consuming traditional food based on wild edible herbs/natural products. Increased interest in local herbal potentials could be a driving force in modelling rural destinations to enrich food tourism offers and provide a new experience. This study aimed to assess the relevance of ethnobotany and traditional knowledge on wild herbs utilization with a focus on increased demand for natural products as a basis for future food tourism offer creation in rural areas. By applying free-listed observations and semi-structured ethnobotanical interview approach data were obtained (n = 169) and quantitatively analyzed using indices of Relative Frequency Citation (RFC), Use Value (UV) and Pearson Correlation Coefficient (PCC). The final results were visualized using the Venn diagram and DIVA-GIS. The results indicate subtle transformation in food tourism demands and new trends in nutrition based on 34 species divided into 7 functional groups along the geographic gradient. Traditional food systems through reviving ethnobotanical knowledge and practices should be a matter of future food tourism management.

Building an interactive web mapping tool to support distributed energy resource planning using public participation GIS

Community solar projects involve the installation of large PV systems whose net outputs are then virtually allocated to customers at other locations. They represent a relatively new model of distributed energy resource (DER) implementation that could help overcome some historical barriers to low-income, disadvantaged community, renter household participation in the ongoing renewable energy transition. Siting community solar assets is a thick and inherently geographic problem however, one which relates to historical patterns of energy infrastructure investment, local urban development, and community socio-demographic change. Creating a more equitable energy system will require planning tools which better coordinate the DER adoption decisions of individual property owners with the grid operators. Interactive decision support tools based on web maps are well suited to addressing this need for improved information sharing and coordination. However, such tools need to be designed and implemented through a process of public participation with stakeholders who explicitly focus on social and environmental justice. Here we describe the process by which one such tool was developed. We also report on several important findings derived from its use relating to current imbalances between local DER supply potential and the grid integration capacity limits which exist within Southern California's disadvantaged communities.

Legislation as an Effort to Oppose the Exploitation of Underage Workers in the Perspective of Human Rights

The current phenomenon is often found in children becoming laborers or workers in home industries. Some of the dominant factors causing children to become laborers were found in the field, including family, environmental influences, local potential and recruitment patterns, educational needs and future orientation, and encouragement from the children themselves. Meanwhile, the reason why employers use children as labor is caused by several things, among others, because the child comes personally to the entrepreneur, offers labor, to enter a child laborer generally through informal procedures, the workforce will be easy to manage and obedient when compared to with adult workers or for reasons of pity/pity rather than being neglected to work on the streets where the conditions are very dangerous, it is better to be recruited as workers. The philosophy of prohibiting children from working or employing children as regulated in the Manpower Law is closely related to efforts to protect children's human rights, which are also guaranteed protection in Law No. 39 of 1999 on Human Rights. Provisions that prohibit the employment of children as regulated in the provisions of Article 68 of the Manpower Law are in line with the provisions of Article 52 paragraph (1) of Law No.39 of 1999 concerning Human Rights, which stipulates that every child has the right to protection by parents, family, community and country. Law Number 23 of 2002, Article 1 Paragraph 2 states that child protection is all activities to guarantee and protect children and their rights so that they can live, grow, develop and participate optimally by human dignity and protection, receive protection from violence and discrimination.

DIVERSITY OF LOCAL MAIZE IN EJIDOS OF THE FRAILESCA REGION OF CHIAPAS, MEXICO

<p><strong>Background</strong>: In studies of local maize diversity, conservation is often identified as a linear process, related to the limited analysis of the implications of technological change, especially improved commercial seed, on local maize potential and its conservation. This generates increasing socio-technical complexity <strong>Objective</strong>: To characterize the potential of local maize present in two ejidos of the Frailesca region of Chiapas, considering the farmers' knowledge about them and the configurations they adopt together with other maize in the context of technological change. <strong>Methodology</strong>: Using the snowball technique, peasant domestic production units that conserve local maize (LM) were identified and samples were collected. The ethnographic method was used to deepen the farmers' knowledge of the local varieties and the configurations they share with other maize. The characteristics of the ear and kernel of the collected LM were described. <strong>Results</strong>: In the selected peasant domestic production units farmers maintain 15 varieties of LM based on a broad knowledge of these varieties; the basis of the selection process, conservation and adaptation to the conditions where they preserve them. According to the parameters of grains and cobs the LM collected are concentrated in three groups and form non-linear configurations with improved maize and other local varieties, in correspondence with the homogenizing technological flow typical of the Frailesca region. I<strong>mplications</strong>: This productive environment where the conservation of LM is developed makes evident the importance of an integrative approach to capture their growing socio-technical complexity. <strong>Conclusions</strong>: The LM potential evidenced permanence and morphological variability despite the homogenizing effect of technological change in the study area, where the socio-technical framework of LM conservation becomes more complex and the broad expert knowledge of farmers on the management of maize diversity acquires greater relevance. </p>

Remote control of spin polarization of topological corner states

In two-dimensional higher-order topological insulators, the corner states are separated by a non-negligible distance. The crystalline symmetries protect the robustness of their corner states with long-range entanglement, which are robust against time-reversal-breaking perturbations. Here, we demonstrate the possibility of direct control of the topological corner states by introducing the spin degree of freedom in a rhombus-shaped Kekul\'e nanostructure with local magnetization and local electric potential. By applying a local magnetization on one corner, the other corner can also be strongly spin polarized. By further applying a local electric potential at the same corner, the sign of the spin polarization can be reversed at both corners. We also prove the robustness of the control of the spin polarization under the disorder. Moreover, we demonstrate the material realization in a $\ensuremath{\gamma}$-graphyne nanostructure with Mn adsorption and Si replacement at one corner by using first-principles calculations. Other higher-order lattices and the shape of the nanostructure are also discussed. Our studies give a showcase of the remote correlation of quantum states in higher-order topological materials for spintronic and quantum applications.

Electronic viscosity and energy relaxation in neutral graphene

We explore hydrodynamics of Dirac fermions in neutral graphene in the Corbino geometry. In the absence of a magnetic field, the bulk Ohmic charge flow and the hydrodynamic energy flow are decoupled. However, the energy flow does affect the overall resistance of the system through viscous dissipation and energy relaxation that has to be compensated by the work done by the current source. Solving the hydrodynamic equations, we find that local temperature and electric potential are discontinuous at the interfaces with the leads as well as the device resistance and argue that this makes Corbino geometry a feasible choice for an experimental observation of the Dirac fluid.

Renewable energy creditors versus renewable energy debtors: Seeking a pattern in a sustainable energy transition during the climate crisis

Considering unpredictable and hastily evolving tipping points (like the impacts of the COVID-19 pandemic, ongoing climate crisis and the war in Ukraine), it is clear that sustainable energy transition and utilization of locally sourced renewable energies must be in the heart of both national, regional, and local energy systems. However, if we take a closer look at the actions undertaken at the local (communal) level, we see enormous diversity of patterns, prerequisites, and implications that drive and affect spatial deployment of renewable energies. Therefore, our research targets to better comprehend the question if individual communities are comparatively involved in the energy transition. We also ask whether the demand and supply of renewable energy is territorially balanced and how these differences (if any) can be justified. We are framing our research by the concepts of energy justice and ecological debt. We thoroughly explore and asses the renewable energy balance on the level of individual communities which is based on data on the installed power capacity potentials and energy consumption in local administration units in Poland (380). Spatial distribution and discrepancies in the deployment of the renewable energy creditors and the renewable energy debtors are detected. Noticeable disproportions were identified among communities where improved utilization of local potential of renewable energy could exceed energy demand (29% of communities). This result is contrasting with communities (71% of communities) that can be, on the other hand, classified as renewable energy debtors. We claim that insufficient support (institution, regulatory, and financial) for expanding local renewable energy systems is a clear barrier when adapting to the climate crisis by balancing the energy demand and supply at the local level.

Calibrated analytical model for magnetic localization of wireless capsule endoscope based on onboard sensing

AbstractWireless capsule endoscopes (WCEs) are pill-sized camera-embedded devices that can provide visualization of the gastrointestinal (GI) tract by capturing and transmitting images to an external receiver. Determination of the exact location of the WCE is crucial for the accurate navigation of the WCE through external guidance, tracking of the GI abnormality, and the treatment of the detected disease. Despite the enormous progress in the real-time tracking of the WCE, a well-calibrated analytical model is still missing for the accurate localization of WCEs by the measurements from different onboard sensing units. In this paper, a well-calibrated analytical model for the magnetic localization of the WCE was established by optimizing the magnetic moment in the magnetic dipole model. The Jacobian-based iterative method was employed to solve the position of the WCE. An error model was established and experimentally verified for the analysis and prediction of the localization errors caused by inaccurate measurements from the magnetic field sensor. The assessment of the real-time localization of the WCE was performed via experimental trials using an external permanent magnet (EPM) mounted on a robotic manipulator and a WCE equipped with a 3-axis magnetic field sensor and an inertial measurement unit (IMU). The localization errors were measured under different translational and rotational motion modes and working spaces. The results showed that the selection of workspace (distance relative to the EPM) could lead to different positioning errors. The proposed magnetic localization method holds great potential for the real-time localization of WCEs when performing complex motions during GI diagnosis.

Circularity by stock in Sri Lanka: Economic necessity meets urban fabric renovation

Persistent fiscal and political mismanagement, together with the financial pressures of the COVID-19 pandemic, have driven Sri Lanka into a social and economic crisis triggering a decrease in national foreign exchange reserves, an inability to purchase vital imports, and an unprecedented rise in internal inflation rates. Within the correspondingly distressed construction sector, the idea of ‘design circularity’ gains natural impetus beyond eco-system protection and responsible consumption views, as a critical strategy for responding to the material and fiscal scarcity of the country’s by-now relatively closed economy. This is also in light of the fact that the post-independence history of industrial policy in the island has produced an urban landscape characterised by large underused and increasingly derelict building stock with a significant potential - and need - to be programmatically reorganised, technically recycled, and spatially and culturally re-designed. This paper moves from the proposition that, for ‘circularity’ to be of use at the scale required, its design application must expand beyond conventional interpretations of material recycling, to acknowledge the overall building fabric as a critical, transformative resource available to be renewed or reborn, with varying degrees of reforms as called by the existing opportunities, underlying programmatic needs, and/or industrial constraints. In facilitating this function, architectural design has an important role to play, as particular sets of design strategies must be employed to handle the inevitable complexities between structure and form, material and content, and product and process, against a reflective understanding of local building logic, challenges and potential. To that end, professional design can help foster design approaches to resolve the technical intricacies of building fabric transformations, to strategise actions concerning work procurement and economic planning, and to provide the leading agency in setting up future-industry configurations. How this approach could inform and affect broad market notions of design circularity for Sri Lanka is evaluated through the review of three projects that focus on different programmatic transformations (residential-to-residential, residential-to-recreational, and commercial-to-recreational), are set within different geographical locales (city, periphery and in-between), and situated in and around Kandy, Sri Lanka’s second largest city. The projects illustrate possible tactics for intervening on the existing fabric whilst considering the benefits of each and articulating the structural challenges for the practices involved.

Confining Bimetal Sites in Porous Metal Silicate Materials for Aerobic Oxidation of Phenols under Mild Conditions

Inspired by the unique catalytic properties of enzymes, numerous biomimetic catalysts have been developed with the intention to realize activation of unreactive reactants under mild conditions; however, the requirement of harsh activation conditions heavily deters their practical applications. We report herein a porous metal silicate (PMS) material PMS-12 that consists of redox-active copper and vanadium metal sites, which exhibits similar catalytic behaviors of enzymes by synergistically activating different reactant molecules and generating local redox potential to facilitate electron and charge transfer, demonstrating the highest catalytic efficiency for aerobic oxidation of phenols to produce highly value-added benzoquinones under mild conditions. Therefore, this work paves a practically applicable strategy for developing high-performance heterogeneous catalysts, which could activate unreactive reactant molecules to produce highly value-added chemicals under mild conditions.

Exploring the Political Potential of the Local State: Building a Dialogue with Sheffield in the 1980s

AbstractThis article explores the political potential of the local state through an engagement with the case of Sheffield City Council in the 1980s. The new municipalism movement has generated renewed interest in the “local” and “urban” as transformative projects. The local state holds a pivotal if problematic role in these debates, often seen as the decisive force facilitating or impeding transformation. In building a dialogue with 1980s Sheffield, we provide a less certain account of the local state's potential. Sheffield occupies an ambiguous position within and beyond traditional municipal labourism and therefore provides a potent example to explore tensions within municipalism between state and autonomist visions of politics. In Sheffield, radical intent turned into a more cautious governmental programme in the city, notwithstanding glimpses of political alternatives. The experience of those years provides insights on the contingencies of bringing movements and state politics together in what was then called “local socialism”.

Targeted treatment of triple-negative-breast cancer through pH-triggered tumour associated macrophages using smart theranostic nanoformulations

Triple-negative breast cancer (TNBC) represents 15–25 % of the new breast cancer cases diagnosed worldwide every year. TNBC is among the most aggressive and worst prognosis breast cancer, mainly because targeted therapies are not available. Herein, we developed a magnetic theranostic hybrid nanovehicle for targeted treatment of TNBC through pH-triggered tumour associated macrophages (TAMs) targeting. The lipid core of the nanovehicle was composed of a Carnaúba wax matrix that simultaneously incorporated iron oxide nanoparticles and doxorubicin (DOX) - a chemotherapeutic drug. These drug-loaded wax nanovehicles were modified with a combination of two functional and complementary molecules: (i) a mannose ligand (macrophage targeting) and (ii) an acid-sensitive sheddable polyethylene glycol (PEG) moiety (specificity). The TAMs targeting strategy relied on the mannose − mannose receptor recognition exclusively after acid-sensitive “shedding” of the PEG in the relatively low tumour microenvironment pH. The pH-induced targeting capability towards TAMs was confirmed in vitro in a J774A.1 macrophage cell line at different pH (7.4 and 6.5). Biocompatibility and efficacy of the final targeted formulations were demonstrated in vitro in the TNBC MDA-MB-231 cell line and in vivo in an M-Wnt tumour-bearing (TNBC) mouse model. A preferential accumulation of the DOX-loaded lipid nanovehicles in the tumours of M-Wnt-tumour bearing mice was observed, which resulted both on an efficient tumour growth inhibition and a significantly reduced off-target toxicity compared to free DOX. Additionally, the developed magnetic hybrid nanovehicles showed outstanding performances as T2-contrast agents in magnetic resonance imaging (r2 ≈ 400–600 mM−1·s−1) and as heat generating sources in magnetic hyperthermia (specific absorption rate, SAR ≈ 178 W·g−1Fe). These targeted magnetic hybrid nanovehicles emerge as a suitable theranostic option that responds to the urgent demand for more precise and personalized treatments, not only because they are able to offer localized imaging and therapeutic potential, but also because they allow to efficiently control the balance between safety and efficacy.

Protruding cantilever microelectrode array to monitor the inner electrical activity of cerebral organoids.

Stem cell-derived cerebral organoids are artificially grown miniature organ-like structures mimicking embryonic brain architecture. They are composed of multiple neural cell types with 3D cell layer organization exhibiting local field potential. Measuring the extracellular electrical activity by means of conventional planar microelectrode arrays is particularly challenging due to the 3D architecture of organoids. In order to monitor the intra-organoid electrical activity of thick spheroid-shaped samples, we developed long protruding microelectrode arrays able to penetrate the inner regions of cerebral organoids to measure the local potential of neurons within the organoids. A new microfabrication process has been developed which, thanks to the relaxation of internal stresses of a stack of materials deposited over a sacrificial layer, allows one to build a protruding cantilever microelectrode array placed at the apex of beams which rise vertically, over two hundred microns. These slender beams inserted deeply into the organoids give access to the recording of local field potential from neurons buried inside the organoid. This novel device shall provide valuable tools to study neural functions in greater detail.

Quasi-bound states and resonant skew scattering in two-dimensional materials with a Mexican-hat dispersion

Mexican-hat dispersion of band electrons in two-dimensional materials attracts a lot of interest, mainly due to the Van Hove singularity of the density of states near the band edge. In this paper, we show that there is one more feature of such a dispersion, which also leads to nontrivial effects. It consists in the fact that the sign of the effective mass in the momentum space near the central extremum is opposite to the sign of the mass outside this region. For this reason, any localized potential that repels quasiparticles in the outer region attracts quasiparticles in the central region and thereby creates quasi-bound states. We study these states in the case when the Mexican-hat dispersion is formed due to the hybridization of the inverted electron and hole bands, and the potential is created by a point defect. The energy and width of the resonance of the local density of states corresponding to a quasi-bound state are found, and it is shown that, under certain conditions, a quasi-bound state can transform into a bound state in a continuum of band states. The presence of quasi-bound states leads to nontrivial effects in the spin-dependent scattering of electrons. Due to the quasi-bound state, the skew scattering is strongly enhanced for electrons with energy near the resonance, and the skewness angle varies over a wide range depending on the energy. In addition, in a certain energy range, a nontrivial effect of scattering suppression appears in the direction opposite to the skewness angle.

Opportunity and Challenges in Transforming Agato Organic Plantation’s Agricultural Activities Into Agro-Edutourism

Agato Plantation is managed by Bina Sarana Bakti Foundation. The Bina Sarana Bakti Foundation is a company that has many activities in the field of plantations and organic farming, which has been running and has had several visits, so it currently needs to develop its activities towards tourism. Educational tourism is a branch of tourism that combines recreation with learning. Edutourism or educational tourism is a form of tourist activity that involves learning experiences for tourists, which can consist of various forms, namely ecotourism, cultural tourism, rural tourism, and student exchanges between educational institutions. This research will develop the area of the community service foundation, which was initially focused on agricultural activities, and develop it towards educational tourism by utilizing local potential. In this case, local potential is all kinds of real potential owned in the form of natural potential, social, cultural, economic and institutional potential, including superior commodities and potential human resources worthy of development. Judging from the potential of agriculture and education, this company has potential in agriculture and education, which can be collaborated to become an agroedutourism tourism activity.

RESEARCH OF A COMBINED HEAT SUPPLY SYSTEM WITH ALTERNATIVE ENERGY SOURCES

The configuration of an energy-efficient combined heat supply system of the educational building of the Odessа Polytechnic National University with alternative energy sources is proposed. An experimental database of wind speed, which is tied to the dislocation of the combined heat supply system, was obtained. The averaged data on the wind speed of the Odesa weather site during the heating period have been adjusted. The conditions for using the energy potential of the wind to create a combined system are considered. A calculation model was obtained for the integral repeatability of the wind speed according to the Weibull probability distribution for the heating period. On the basis of the developed mathematical model of the dynamics of thermal processes of the elements of the combined system and the model of the energy potential of the wind, the modes of operation of the heat supply system when the temperature of the outside air changes are investigated. With the application of a mathematical model of the heating system, the optimal daily schedule of the intermittent operation of the heating system in terms of energy efficiency is given. The optimal schedules of the electrical and thermal load of the elements of the combined heat supply system in the intermittent heating mode have been worked out. Daily schedules of charge-discharge modes of the water heat accumulator and the electric accumulator battery have been developed, which ensure optimal loading of the system elements. The evaluation of the effectiveness of the substitution coefficient at a change in the outside air temperature from 5 to –15 °С was carried out. The energy balances of the combined system were studied in order to substantiate the rational parameters of its elements and the system as a whole. The possibility of creating a highly efficient autonomous heating system based on modern energy technologies using alternative energy sources and taking into account their local potential has been confirmed.
