Situación de la educación virtual en el sector rural ecuatoriano
Authors: Iñiguez Apolo Lenin Mauricio , Robles Riofrio Ashley Mariuxi , Inga Saldarriaga William Josue
Published: October 2022

Este ensayo tiene como objetivo analizar la situación de la educación virtual en las zonas rurales del Ecuador, en tal sentido se desarrolló un estudio de revisión bibliográfica, sistematizado a través de los métodos de análisis de contenido, hermenéutico y analítico-sintético, mediante los cuales se estudiaron y resumieron los contenidos de libros, artículos científicos y tesis de grado referentes al tema objeto de estudio. Entre los principales resultados están: la educación virtual en las zonas rurales en el Ecuador es prácticamente inexistente, como consecuencia de la falta de recursos económicos e infraestructura tecnológica que no garantizan la disponibilidad de computadoras y dispositivos conectados a Internet. Existe un desequilibrio entre la educación que reciben los escolares que residen en las ciudades y lugares con acceso a Internet y los que viven en las zonas rurales. Como alternativa para aliviar esta situación se pueden utilizar los “infocentros” de las parroquias e instalar otras computadoras en las comunidades; pero, ante todo es urgente contar con la voluntad política del estado, gobiernos locales y autoridades competentes para revertir esta lamentable realidad.

Distributed leadership at a South African university of technology : a multi-stakeholder model
Authors:   , Haniff Naseem
Published: October 2022

Leadership has been an area of interest for millennia, but never more so than within a 21st century VUCA (volatile, uncertain, complex and ambiguous) world. Globalisation, massification, rapid socio-economic changes in tandem with the demands of the Fourth Industrial Revolution are all challenges faced by higher education institutions internationally. South African higher education has not escaped these leadership challenges, but in addition faces its own unique issues, post-apartheid. The country’s democratic dispensation required that institutional governance and leadership be shared and participative, which aligns well to a distributed leadership stance. However, more than two decades later, events such as # FeesMustFall national campaigns, the strident student discourse and the rising clamour for transformation, questions if real change has actually taken place. This study examined the issue of university transformation by assessing multi-stakeholder participation in leadership and governance at a South African University of Technology. Taking cognisance of the multiplicity of issues facing higher education institutions it was important to utilise robust research methods, hence, the paradigm choice of a systems thinking worldview and complexity sciences. This study used multi-method research employing the Viable System Model (VSM) with the rich picture technique of the Soft System Methodology (SSM). Data was collected through qualitative interviews, respondent observation and archival data and examined using thematic analysis. Using the VSM as a diagnostic tool, enabled weaknesses and strengths of the institution to be identified, which informed the building of an institution specific model of distributed leadership. The findings of this study demonstrated institutional viability, albeit, in a hierarchical, bureaucratic manner. It nevertheless highlighted weaknesses of ‘soft’ or people-centred issues. Other identified concerns was that the university was more inward focused, on the ‘here and now’, often ignoring the ‘outside and then’ that is, the external environment and could imply that the institution is not well placed to handle national and global stressors. The model of distributed leadership addresses this deficit. This study established the appropriateness and applicability of using a systems thinking approach namely the VSM as a diagnostic tool to assess institutional shortcomings. In this way, it enabled appropriate recommendations and suggestions to improve the institutions viability to address the complexities facing 21st century higher educational institutions

Identifying and accounting for the Coriolis Effect in satellite NO2 observations and emission estimates
Authors: Potts Daniel A. , Timmis Roger , Ferranti Emma J. S. , Vande Hey Joshua D.
Published: October 2022

Abstract. Recent developments in atmospheric remote sensing from satellites have made it possible to resolve daily emission plumes from industrial point sources, around the globe. Wind rotation aggregation coupled with statistical fitting is commonly used to extract emission estimates from these observations. These methods are used here to investigate how the Coriolis Effect influences the trajectory of observed emission plumes, and to assess the impact of this influence on satellite derived emission estimates. Of the 17 industrial sites investigated, nine showed the expected curvature for the hemisphere they reside in. Five showed no or negligible curvature, and two showed opposing or unusual curvature. The sites which showed conflicting curvature all reside in topographically diverse regions, where strong meso-gamma scale (2–20 km) turbulence dominates over larger synoptic circulation patterns. For high curvature cases the assumption that the wind-rotated plume aggregate is symmetrically distributed across the downwind axis breaks down, which impairs the quality of statistical fitting procedures. Using NOx emissions from Matimba power station as a test case, not compensating for Coriolis curvature resulted in an10 underestimation of ∼ 9 % on average for years 2018 to 2021. This study is the first formal observation of the Coriolis Effect and its influence on satellite observed emission plumes, and highlight both the variability of emission calculation methods and the need for a standardised scheme for this data to act as evidence for regulators.
Source apportionment and evolution of N-containing aerosols at a rural cloud forest in Taiwan by isotope analysis

Published: October 2022

Abstract. Ammonium and nitrate are major N-containing aerosol components. The deposition of N-containing aerosols has impacts on regional ecology and the biogeochemical cycle. In this study, aerosols in a rural cloud forest (Xitou in Taiwan) were studied using 15N and 18O
isotope analysis to assess the sources and formation pathways of the local
N-containing aerosols linking to a metropolitan. Aerosol samples of
different size ranges were collected using a micro-orifice uniform deposit
impactor (MOUDI) on a half-day basis in December 2018. The chemical
functional groups were analyzed using a Fourier-transform infrared
spectroscopy with attenuated total reflection (FTIR-ATR) technique, while the isotope analysis was performed using a gas chromatography–isotope ratio mass spectrometer (GC–IRMS). The average measured aerosol concentration (PM10) was 0.98 (ranging from 0.15 to 3.31) and 0.25 (ranging from 0.00 to 1.51) µg m−3 for NH4+ and NO3-, respectively. In general, a higher concentration than nighttime was observed during the daytime by a factor of 1.5–6, likely due to the transportation of pollutants from upper-stream urban and industrial regions through the local sea breeze combined with valley wind. The presence of fog can further elevate the concentration by a factor of 2–3, resulting from the stronger inversion and lower boundary layer height. The higher NH4+ concentration in fine particles under foggy conditions corresponds to submicron-sized NO3- formation via aqueous-phase dissolution with NH4+ neutralization. Furthermore, the higher RH during fog events shifted the mass distribution of aerosol functional groups to a larger mode size. By comparing the δ15N value directly or through the analysis using a statistical isotope mixing model, MixSIAR, NH4+ probably originated from the industries, coal-fired power plants (CFPPs), or fertilizer plants, while NO3- might be contributed from the CFPP, industrial or urban sources. The overall δ18O of NO3- is +72.66 ‰ ± 3.42 ‰, similar to that in other winter Asian studies, suggesting the major formation pathway via O3 oxidation (δ18O=+72.5 ‰ to 101.67 ‰). However, a lower δ18O (<+67 ‰) for particles less than 0.56 µm during foggy daytime suggests the local contribution via the peroxyl radical oxidation before partitioning into aerosol phase under foggy conditions. Overall, the δ15N and δ18O distribution profiles as a function of particle size in the studied rural forest site reveal the evolution of aerosol composition from remote coastal regions with chemical processes along the transport process, which can be further affected by weather conditions such as fog events.
Downscaled climate change scenarios for Central America

Published: October 2022

Abstract. The intersectoral workshop held in December 2016 among the Ibero-American
networks on water, climate change and meteorology, identified the need of
downscaled climate change scenarios for Central America. Such scenarios
would be developed by National Meteorological and Hydrological Services in
the region, based on a common methodology, allowing the assessment of
climate change impacts on water resources and extreme hydro-meteorological
events. This project was supported by the International and Ibero-American
Foundation for Administration and Public Policies of Spain in the framework
of the EUROCLIMA+ programme. One final outcome of the project has been a
freely accessible web viewer, installed on the Centro Clima webpage
(https://centroclima.org/escenarios-cambio-climatico/, last access: 26 September 2022), managed by the Regional Committee on Hydraulic Resources of the Central American Integration System, where all information generated during the project is available for consultation and data downloading by the different sectors of users. A key element in this project has been to integrate many downscaled
projections based on different methods (dynamical and statistical),
totalizing 45 different projections, and aiming at estimating the
uncertainty coming from different sources in the best possible way. Another
essential element has been the strong involvement of the different user
sectors through national workshops, first, at the beginning of the project
for the identification and definition of viewer features, and then for the
presentation of results and planning of its use by prioritized sectors. In a second phase of the project, a regional working group made up of
experts from the participating National Meteorological and Hydrological
Services will be in charge of viewer maintenance and upgrade, including new
sectoral parameters, developed in collaboration with interested users, and
computation and addition of new downscaled projections from CMIP6 in
collaboration with the State Meteorological Agency of Spain.
Distinguishing the vegetation and soil component of δ13C variation in speleothem records from degassing and prior calcite precipitation effects

Published: October 2022

Abstract. The carbon isotopic signature inherited from soil/epikarst processes may be modified by degassing and prior calcite precipitation (PCP) before its imprint on speleothem calcite. Despite laboratory demonstration of PCP effects on carbon isotopes and increasingly sophisticated models of the governing processes, to date, there has been limited effort to deconvolve the dual PCP and soil/epikarst components in measured speleothem isotopic time series. In this contribution, we explore the feasibility, advantages, and disadvantages of using trace element ratios and δ44Ca to remove the overprinting effect of PCP on measured δ13C to infer the temporal variations in the initial δ13C of dripwater. In 8 examined stalagmites, the most widely utilized PCP indicators Mg/Ca and δ44Ca covary as expected. However, Sr/Ca does not show consistent relationships with δ44Ca so PCP is not universally the dominant control on Sr/Ca. From δ44Ca and Mg/Ca, our calculation of PCP as fCa, fraction of initial Ca remaining at the deposition of the stalagmite layer, yields multiple viable solutions depending on the assumed δ44Ca fractionation factor and inferred variation in DMg. Uncertainty in the effective fractionation of δ13C during degassing and precipitation contributes to uncertainty in the absolute value of estimated initial δ13C. Nonetheless, the trends in initial δ13C are less sensitive to these uncertainties. In coeval stalagmites from the same cave spanning 94 to 82 ka interval, trends in calculated initial δ13C are more similar than those in measured δ13C, and reveal a common positive anomaly initial δ13C during a stadial cooling event. During deglaciations, the trend of greater respiration rates and higher soil CO2 is captured in the calculated initial δ13C, despite the tendency of higher interglacial dripwater situation to favor more extensive PCP.

Published: October 2022

Abstract. This article describes the equipment, and its advantages, used for in-situ ground measurements of thunderstorm phenomena using measuring cars. By using all-sky high-speed cameras, radio receivers, and electric field measurements, typical lightning discharges in the central Europe region have been characterized. Measurements of ionizing radiation during storms using a gamma spectrometer were also performed. At the ground level, no ionizing radiation originating in the storm cloud was detected even though during other experiments, using the same equipment at lower altitudes corresponding to the lower part of the storm clouds, ionizing radiation was detected. We showed that radio antennas with appropriately constructed receivers and all-sky high-speed cameras are devices that can significantly contribute to the understanding of processes taking place in the storm cloud during lightning discharges. On the contrary, measurements of the vertical electric field did not provide any new information about the processes occurring in the thunderclouds.
New secondary phosphate mineral occurrences and their crystal chemistry, at the Hagendorf Süd pegmatite, Bavaria

Published: October 2022

Abstract. First occurrences from the Hagendorf Süd pegmatite of the secondary
phosphate minerals kenngottite,
Mn32+Fe43+(PO4)4(OH)6(H2O)2;
allanpringite, Fe33+(PO4)2(OH)3 ⚫ 5H2O; iangreyite,
Ca2Al7(PO4)2(PO3OH)2(OH,F)15 ⚫ 8H2O; and nizamoffite, MnZn2(PO4)2(H2O)4, are
reported with characterisation of their crystal chemistry and phase
associations. A synchrotron single-crystal structure refinement for
kenngottite shows that it has the same level of disordering (75 %/25 %)
of Fe3+ in adjacent octahedra along the 5 Å axis as for
type-locality kenngottite from Krásno, Czech Republic. This is explained
in terms of 1 : 1 fine-scale mixing of domains of ordered kenngottite-type and
souzalite-type structures. Allanpringite occurs in an unusual epitaxial
relationship to associated strunzite. The epitaxy is explained by the close
metrical and structural match of common planes in the two minerals, (010)
for allanpringite and (100) for strunzite. Iangreyite occurs in close
association with perhamite in 30 µm spheroids. The characterisation
results support a paragenesis of iangreyite from perhamite by selective
leaching of silica from the layer structure of perhamite and rejoining of
the layers by fusion of AlO4 tetrahedra from adjacent layers into
AlO2(OH)3 trigonal bipyramids.
Multi-million year cycles in modelled δ13C as a response to astronomical forcing of organic matter fluxes
Authors: Leloup Gaëlle , Paillard Didier
Published: October 2022

Abstract. Along with 400 kyr periodicities, multi-million year cycles have been found in δ¹³C records over different time periods. A ~8–9 Myr periodicity is found throughout the Cenozoic, and part of the Mesozoic. The robust presence of this periodicity in δ¹³C records suggests an astronomical origin. However, this periodicity is barely visible in the astronomical forcing. Due to the large fractionation factor of organic matter, its burial or oxidation produces large δ¹³C variations for moderate carbon variations. Therefore, astronomical forcing of organic matter fluxes is a plausible candidate to explain the oscillations observed in the δ¹³C records. So far, modelling studies forcing astronomically the organic matter burial have been able to produce 400 kyr and 2.4 Myr cycles in δ¹³C, but were not able to produce longer cycles, such as 8–9 Myr cycles. Here, we propose a mechanism that could explain the presence of multi-million year cycles in the δ¹³C records, and their stability over time, as a result of preferential periodicity locking to multiples of astronomical forcing periods. With a simple non linear conceptual model for the carbon cycle that has multiple equilibria, we are able to extract longer periods than with a simple linear model, and more specifically, multi-million year periods.
Multidimensional encoding of restricted and anisotropic diffusion by double rotation of the q-vector
Authors: Jiang Hong , Svenningsson Leo , Topgaard Daniel
Published: October 2022

Abstract. Diffusion NMR and MRI methods building on the classic pulsed gradient spin echo sequence are sensitive to many aspects of translational motion, including time/frequency-dependence (“restriction”), anisotropy, and flow, which leads to ambiguities when interpreting experimental data from complex heterogeneous materials such as living biological tissues. Higher specificity to restriction or anisotropy can be obtained with, respectively, oscillating gradient or tensor-valued encoding which nevertheless both have some sensitivity to the property not being of direct interest. Here we propose a simple scheme derived from the “double rotation” technique in solid-state NMR to generate a family of modulated gradient waveforms allowing for comprehensive exploration of the two-dimensional frequency-anisotropy space and convenient investigation of both restricted and anisotropic diffusion with a single multidimensional acquisition protocol. The method is demonstrated by measuring multicomponent isotropic Gaussian diffusion in simple liquids, anisotropic Gaussian diffusion in a polydomain lyotropic liquid crystal, and restricted diffusion in a yeast cell sediment.
Dynamic modeling and experiment of hind leg swimming of beaver-like underwater robot
Authors: Chen Gang , Wang Zhenyu , Tu Jiajun , Wang Donghai
Published: October 2022

Abstract. When the beaver-like underwater robot is swimming, its hind legs provide the
main propulsion force for the body, which is the source of power for the
robot's movement. Hind leg swimming dynamics is the basis for analyzing the
generation and change of propulsion force during the robot swimming process,
which directly determines how the robot swimming trajectory is planned.
However, there are few researches on the swimming dynamics of the hind leg
of a beaver-like underwater robot. This paper proposes a rigid–liquid fusion
dynamics modeling method, which simplifies the swimming dynamics of hind
legs of beaver-like robot to hydrodynamics of webbed feet and rigid body
dynamics of thighs and calves. The hydrodynamics of the bendable webbed foot is
established based on the integral hydrodynamics method, and the rigid body
dynamic model of the thigh and calf is constructed using the Newton–Euler
method. Through the force transmission, the overall swimming dynamic model
of the hind leg is established, and the propulsion and lift force of the hind leg
to body are obtained. The ANSYS Fluent simulation of the movement of robot's
hind leg and underwater single-leg swimming experiments verify the
correctness and effectiveness of the dynamics model. Comparing the theory,
simulation, and experimental results of the propulsion and lift force of the
robot's hind legs under bionic swimming, increased amplitude swimming, and
reduced amplitude swimming, it further verifies the correctness of the
proposed rigid–liquid fusion dynamic modeling method, and proves the
superiority of the robot's bionic swimming trajectory. This study can
provide new ideas for the leg dynamic modeling of underwater swimming robots
with bendable webbed feet, and lay a theoretical foundation for exploring
the swimming mechanical process of underwater robots.
Mechanical compaction mechanisms in the input sediments of the Sumatra subduction complex – insights from microstructural analysis of cores from IODP Expedition 362
Authors: Lahiri Sivaji , Milliken Kitty L. , Vrolijk Peter , Desbois Guillaume , Urai Janos L.
Published: October 2022

Abstract. The input sediments of the North Sumatra subduction zone margin, drilled
during IODP Expedition 362, exhibit remarkable uniformity in composition and
grain size over the entire thickness of the rapidly deposited Nicobar Fan
succession (seafloor to 1500 m b.s.f.), providing a unique opportunity to study
the micromechanisms of compaction. Samples were prepared from dried core
samples (from Sites U1480 and U1481) by both Ar-ion cross-section polishing
and broad ion beam cutting and imaged with a field-emission scanning
electron microscope (SEM). The shallowest samples (seafloor to 28 m b.s.f.)
display a sharp reduction in porosity from 80 % to 52 % due to collapse
of large clay-domain surrounding matrix pores associated with rotation and realignment
of clay platelets parallel to the bedding plane. The deeper succession
(28 to 1500 m b.s.f.) exhibits less rapid reduction in porosity from 52 %
to 30 % by the progressive collapse of silt-adjacent larger pores through
bending as well as subsequent sliding and/or fracturing of clay particles. In addition,
there is a correlated loss of porosity in the pores too small to be resolved
by SEM. Clastic particles show no evidence of deformation or fracturing with
increasing compaction. In the phyllosilicates, there is no evidence for
pressure solution or recrystallization: thus, compaction proceeds by
micromechanical processes. An increase in effective stress up to 18 MPa
(∼ 1500 m b.s.f.) causes the development of a weakly aligned
phyllosilicate fabric mainly defined by illite clay particles and mica
grains, while the roundness of inter-particle pores decreases as the pores
become more elongated. We propose that bending of the phyllosilicates by
inter-particle slip may be the rate-controlling mechanism. Pore size distributions show that all pores within the compactional force
chain deform, irrespective of size, with increasing compactional strain.
This arises because the force chain driving pore collapse is localized
primarily within the volumetrically dominant and weaker clay-rich domains;
pores associated with packing around isolated silt particles enter into the
force chain asynchronously and do not contribute preferentially to pore loss
over the depth range studied.
Evaluating simplifications of subsurface process representations for field-scale permafrost hydrology models
Authors: Gao Bo , Coon Ethan T.
Published: October 2022

Abstract. Permafrost degradation within a warming climate poses a
significant environmental threat through both the permafrost carbon feedback
and damage to human communities and infrastructure. Understanding this
threat relies on better understanding and numerical representation of
thermo-hydrological permafrost processes and the subsequent accurate
prediction of permafrost dynamics. All models include simplified
assumptions, implying a tradeoff between model complexity and prediction
accuracy. The main purpose of this work is to investigate this tradeoff when
applying the following commonly made assumptions: (1) assuming equal density
of ice and liquid water in frozen soil, (2) neglecting the effect of
cryosuction in unsaturated freezing soil, and (3) neglecting advective heat
transport during soil freezing and thaw. This study designed a set of 62
numerical experiments using the Advanced Terrestrial Simulator (ATS v1.2) to
evaluate the effects of these choices on permafrost hydrological outputs,
including both integrated and pointwise quantities. Simulations were
conducted under different climate conditions and soil properties from three
different sites in both column- and hillslope-scale configurations. Results
showed that amongst the three physical assumptions, soil cryosuction is the
most crucial yet commonly ignored process. Neglecting cryosuction, on
average, can cause 10 %–20 % error in predicting
evaporation, 50 %–60 % error in discharge, 10 %–30 % error in thaw depth, and 10 %–30 % error in soil temperature
at 1 m beneath the surface. The prediction
error for subsurface temperature and water saturation is more obvious at
hillslope scales due to the presence of lateral flux. By comparison, using
equal ice–liquid density has a minor impact on most hydrological metrics of
interest but significantly affects soil water saturation with an averaged
5 %–15 % error. Neglecting advective heat transport
presents the least error, 5 % or even much lower, in most metrics of
interest for a large-scale Arctic tundra system without apparent influence
caused by localized groundwater flow, and it can decrease the simulation time
at hillslope scales by 40 %–80 %. By challenging these
commonly made assumptions, this work provides permafrost hydrology
scientists an important context for understanding the underlying physical
processes, including allowing modelers to better choose the appropriate
process representation for a given modeling experiment.
Validation of Turbulence Intensity as Simulated by the Weather Research and Forecasting Model off the U.S. Northeast Coast
Authors: Tai Sheng-Lun , Berg Larry K. , Krishnamurthy Raghavendra , Newsom Rob , Kirincich Anthony
Published: October 2022

Abstract. Turbulence intensity (TI) is often used to quantify the strength of turbulence in wind energy applications and serves as the basis of standards in wind turbine design. Thus, accurately characterizing the spatiotemporal variability of TI should lead to improved predictions of power production. Nevertheless, turbulence measurements over the ocean are far less prevalent than over land due to challenges in instrumental deployment, maintenance, and operation. Atmospheric models such as mesoscale (weather prediction) and large-eddy simulation (LES) models are commonly used in wind energy industry to assess the spatial variability of a given site. However, the TI derivation from atmospheric models have not been well examined. An algorithm is proposed in this study to realize online calculation of TI in the Weather Research and Forecasting (WRF) model. Simulated TI is divided into two components depending on scale, including sub-grid (parameterized based on turbulence kinetic energy (TKE)) and grid resolved. Sensitivity of sea surface temperature (SST) on simulated TI is also tested. An assessment is performed by using observations collected during a field campaign conducted from February to June 2020 near the Woods Hole Oceanographic Institution ’s Martha’s Vineyard Coastal Observatory. Results show while simulated TKE is generally smaller than lidar-observed value, wind speed bias is usually small. Overall, this leads to a slight underestimation in sub-grid scale estimated TI. Improved SST representation subsequently reduces model biases in atmospheric stability as well as wind speed and sub-grid TI near the hub height. Large TI events in conjunction with mesoscale weather systems observed during the studied period pose a challenge to accurately estimate TI from models. Due to notable uncertainty in accurately simulating those events, it suggests summing up sub-grid and resolved TI may not be an ideal solution. Efforts in further improving skills in simulating mesoscale flow and cloud systems are necessary as the next steps.
Políticas de vivienda con perspectiva de género: análisis comparado del marco normativo autonómico
Authors: Alonso Álvarez Alba , Paleo Mosquera Natalia , Diz Otero Isabel
Published: October 2022

Este artículo tiene como objetivo analizar la incorporación de la perspectiva de género en las políticas de vivienda en España. Para ello, en primer lugar, se examina la literatura relativa a la transversalización de la igualdad y el desarrollo de la política de vivienda, prestando especial atención al caso español. Seguidamente, y partiendo del marco teórico extraído de esta revisión bibliográfica, se analiza el contenido de hasta 55 textos legales en materia de igualdad, violencia de género y vivienda correspondientes a las 17 Comunidades Autónomas (CCAA). El estudio pone de manifiesto que las CCAA han utilizado los instrumentos legislativos analizados para incorporar la perspectiva de género en las políticas sectoriales de vivienda. No obstante, las diferencias territoriales observadas en relación al enfoque y el tipo de actuaciones desarrolladas permiten distinguir analíticamente tres modelos de intervención – de bienestar, dual débil y dual fuerte-. En este sentido, este trabajo supone una contribución no solo para los estudios sobre políticas públicas de género y vivienda, sino que también puede resultar de interés para toda aquella literatura focalizada en los análisis sobre los regímenes autonómicos de bienestar.
Characteristics and uses of propolis
Authors: Benedek Csilla , Veresné Bálint Márta
Published: October 2022

Propolis (bee glue) is an extremely valuable “byproduct” of beekeeping. Its ingredients include many bioactive substances that have a beneficial effect on the human body, which is why propolis has been used by mankind for thousands of years, mainly for medicinal and occasionally cosmetic purposes. Many medicinal and cosmetic products are still produced from the substance today. Its composition varies considerably depending on the geographical location and the health of the producing bees. Its most important components are polyphenolic compounds (phenolic acids, flavonoids, flavonoid esters, diterpenes, sesquiterpenes), lignans, aromatic aldehydes, alcohols, amino acids, fatty acids, organic acids, hydrocarbons, vitamins and minerals. Propolis can be considered a medicinal food. Extracts made from it possess antibacterial, antiviral and antifungal effects. Propolis, in limited quantities, is also suitable for human consumption. The safe dose of propolis for healthy people is 70 mg/day. With our manuscript, we intend to provide a brief review of the literature on the beneficial effects of propolis on human health.

A flexitariánusok a mindenevők után a legnagyobb táplálkozási csoporttá váltak, jelentős szerepük van a hús és egyéb állati eredetű termékek fogyasztásának hatékony csökkentésében és ezáltal a klímaváltozás elleni küzdelemben. Figyelembe véve mindazokat, akik aktívan csökkentik vagy teljesen elhagyják legalább bizonyos állati eredetű termékek fogyasztását, beleértve a vegetariánusokat, peszkateriánusokat és flexitariánusokat, ez a csoport a teljes lakosság 30,8%-át teszi ki: az európaiak 10-30%-a már nem tartja magát teljes mértékben húsevőnek. Mindazonáltal lényeges különbségek mutatkoznak a magukat flexitariánusnak tekintő és/vagy annak minősített fogyasztók arányában. Ezen túlmenően a flexitariánus étrend definíciójának vagy legalább egy széles körű konszenzusnak a hiánya még nehezebbé teszi ezen fogyasztói csoport méretének megbecsülését. Miért lehet mégis hasznos a flexitariánusság besorolása, és ez miért támogatja a fenntartható élelmiszer-fogyasztást? Szigorú szabályok betartása helyett hatékonyabb lehet a fogyasztók azon törekvésének erősítése, hogy saját szándékuk szerint kövessenek egy fenntarthatóbb étrendet (például egy flexitariánus étkezési mintát). Cikkünk különböző élelmiszer fogyasztási mintákat ír le a mindenevőktől a reduk-cionistákon (hús fogyasztást csökkentőkön), flexitariánusokon és vegetariánusokon át a vegánokig, és ahol lehetséges, definíciókat és adatokat adok meg az egyes étkezési mintákat követő fogyasztók arányáról.
