European rural development policy approaching health issues: An exploration of programming schemes

Malnutrition, obesity, type 2 diabetes, micronutrient deficiencies, and the increase in non-communicable diseases are among the future European key challenges in health and welfare. Agriculture and rural development policies can positively contribute to a healthier and nutritious supply of food. The objective of the research is to analyze to what extent European 2007-2013 and 2014-2020 rural development programmes address the nexus between agriculture, food, health, and nutrition to respond to the evolving dietary needs. The research carries out a quali-quantitative content analysis on all 210 European rural development programmes. Results show that the interconnection between agriculture, food, health, and nutrition is present, with differences in the European agricultural and rural policy programming periods. The main interlinking issues of the nexus are food safety, food quality, diseases, nutritional aspect, animal health and welfare, plant health, and environmental health. Healthier and nutritious food-related issues are emerging, addressing dietary needs, and sustaining consumer food trends. Healthy and nutritious food is pursued by combating foodborne communicable diseases and non-communicable diseases. The future Common Agricultural Policy, including its rural dimensions, should support the consumption of healthy foods produced in ways that are environmentally and economically sustainable

Innovative digital technologies for purchasing and consumption in urban and regional agro-food systems: A systematic review

The use of digital technologies in the agro-food sector is growing worldwide, and applications in the urban and regional food systems represent a relevant segment of such growth. The present paper aims at reviewing the literature on which and how digital technologies support urban and regional agro-food purchasing and consumption, as well as their characteristics. Data collection was performed on Scopus and Web of Science. Articles were selected using a research string and according to specific inclusion and exclusion criteria. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow approach was adopted to explain data screening and selection. The 57 resulting studies were included in the final qualitative analysis, which explored the characteristics of the research studies and of the digital technologies analysed. Most of the studies analysed concerned the implications of digital technologies on local food consumption, especially focusing on consumption, primary production and hotel-restaurant-caf\ue9-catering sector (HORECA), and to a limited extent on the retail sector. Consumers and farmers are the main targets of Information and Communications Technology (ICT) tools, whose principal aims are providing information on agro-food products and enhancing networking along the food supply chain. Analysing digital technologies allows a better understanding of their most popular features in order to support their spread among citizens. Digital technologies, and particularly Apps, can be a valuable instrument to strengthen agro-food chain actor relations and to promote urban and regional food systems

Food chains and value system: the case of potato, fruit, and cheese

The aim of the paper is to analyse patterns of value system sharing along food chains, so to explore the agro-food enterprises capacity to be competitive and sustainable. The research focused on three food chains: potato, fruit, and Grana cheese of Emilia Romagna region. The paper adopts the value system approach. The methodology is aimed at creating a consolidated financial statement for each food chain so to re-create the chain operating profit and identify how this is shared among the different food chain stages. The analysis is carried out on 189 enterprises for the potato chain, 187 for the fruit chain and 203 for the cheese chain. The number of enterprises was invariable over the 5 year 2003-2007, leading to some 2,900 financial statement analysis. The chains analysed show differences. In the potato and fruit chains 35% of value is created by distribution, whereas in cheese chain only 13.6%. Over the five years value decreases 5% in fruit and potato and 9% in cheese. The lack of adequate strategic food chain partnership allows an increasing retail market power over the whole chain at the expenses of the primary sector entailing a declining sustainability for all chain actors.food chain, value system, profitability, potato, fruit, cheese, Agricultural and Food Policy,

Value sharing and food system dynamics for milk, tomato, and cereals food chains

The aim of the paper is to analyse value sharing and food system dynamics of milk, tomato, and cereals food chains, so to explore the agro-food enterprises capacity to be competitive and sustainable. The paper is based on the functionalist approach of Malassis and the notion of the system of the General Systems Theory. The methodology is aimed at creating a consolidated financial statement for each food chain so to re-create the chain value and identify how this is shared among the different food chain stages. The analysis is carried out on primary and secondary data: around 2400 financial statements concerning 480 enterprises from 2003 to 2007 and stakeholders\u2019 interviews. Results show that value is usually created in the processing and distribution stages, to the detriment of the primary sector, and that the retail managing practices tend to impose damaging structural changes on farms whose profitability is at times becoming sustainable only thanks to European subsidies. To conclude, there is evidence of inadequate definition of strategic and network alliance along the chain. Competitiveness is still a concept achieved by single food chain stages against others and food chain internal competition entails a declining sustainability of small farms and enterprises

Determination of the corrosion current density in low conductivity media: the use of microelectrodes to minimize the ohmic drop

The gravimetric and electrochemical tests are the most common techniques used in determining the corrosion rate. However, the use of electrochemical polarization is limited to electrolytes with sufficient conductivity for which Tafel curves are linear. In this study, we investigated a technique in which working microelectrodes of AISI 1020 steel were used to obtain the Tafel curves in diesel oil. The strategy was to reduce the electrode area and hence the ohmic drop. The diameter of the microelectrode was reduced to a value where the compensation of the Tafel curves became unnecessary. The results showed that for electrodes with diameters below 50 μm, the ohmic drop tends to a minimum and independent of the microelectrode diameter.32532

Electrolytic removal of metals using a flow-through cell with a reticulated vitreous carbon cathode

The aim of the present study was to establish an electrolytic method for the removal of metals from wastewater using a three dimensional, reticulated vitreous carbon cathode. During the development of the experimental set up, particular attention was paid to the electrolyte flow rate and to the cathode porosity. The electrolytic cell employed potential values in such a way that the metals reduction reaction occurred under mass transport control. These potentials were determined by hydrodynamic voltammetry on a vitreous carbon rotating disc electrode. The cell proved to be efficient in removing copper, zinc and lead and it was able to reduce the levels of these metals from 50 mg/L to 0.1 mg/L.O objetivo do presente trabalho foi estabelecer um processo eletrolítico para remover metais de efluentes aquosos usando um catodo tridimensional de carbono vítreo reticulado.

Considerations on the hydrogen peroxide electrogeneration

This paper presents some results that may be used as previous considerations to a hydrogen peroxide electrogeneration process design. A kinetic study of oxygen dissolution in aqueous solution is carried out and rate constants for oxygen dissolution are calculated. Voltammetric experiments on vitreous carbon cathode shown that the low saturation concentration drives the oxygen reduction process to a mass transfer controlled process which exhibits low values of limiting currents. Results have shown that the hydrogen peroxide formation and its decomposition to water are separated by 400 mV on the vitreous carbon surface. Diffusion coefficients for oxygen and hydrogen peroxide are calculated using data taken from Levich and Tafel plots. In a series of bulk electrolysis experiments hydrogen peroxide was electrogenerated at several potential values, and concentration profiles as a function of the electrical charged passed were obtained. Data shown that, since limiting current plateaus are poorly defined onto reticulated vitreous carbon, cathodic efficiency may be a good criterion for choosing the potential value in which hydrogen peroxide electrogeneration should be carried out.25225

Is Brain-Derived Neurotropic Factor Methylation Involved in the Association Between Prenatal Stress and Maternal Postnatal Anxiety During the COVID-19 Pandemic?

BackgroundThe COVID-19 pandemic is a collective trauma that may expose susceptible individuals to high levels of stress. Pregnant women represent a high-risk population, considering that pregnancy is a period of heightened neuroplasticity and susceptibility to stress through epigenetic mechanisms. Previous studies showed that the methylation status of the BDNF gene is linked with prenatal stress exposure. The goals of this study were (a) to assess the association between pandemic-related stress and postnatal anxiety and (b) to investigate the potential role of maternal BDNF methylation as a significant mediator of this association. MethodsIn the present study, we report data on the association among pandemic-related stress during pregnancy, maternal BDNF methylation, and postnatal anxiety symptoms. Pandemic-related stress and postnatal anxiety were assessed through self-report instruments. BDNF methylation was estimated in 11 CpG sites in DNA from mothers' buccal cells. Complete data were available from 108 mothers. ResultsResults showed that pandemic-related stress was associated with an increased risk of postnatal anxiety, r = 0.20, p < 0.05. CpG-specific BDNF methylation was significantly associated with both prenatal pandemic-related stress, r = 0.21, p < 0.05, and postnatal maternal anxious symptoms, r = 0.25, p = 0.01. Moreover, a complete mediation by the BDNF CpG6 methylation emerged between pandemic-related stress during pregnancy and postnatal maternal anxiety, ACME = 0.66, p < 0.05. ConclusionThese findings suggest that BDNF epigenetic regulation by pandemic-related stress might contribute to increase the risk of anxiety in mothers. Policymakers should prioritize the promotion of health and wellbeing in pregnant women and mothers during the present healthcare emergency
