FUNCTIONAL SHORT FOOD SUPPLY CHAINS IN THE FIELD OF ROMANIAN RURAL TOURISM. CASE STUDY: HARGHITA AND NEAMȚ COUNTIES

Nowadays, one cannot talk about an authentic rural tourism within a certain destination without emphasizing the local cultural heritage (cultural landscape, customs and traditions, gastronomy and so on). In the existing context, the local gastronomy is perceived as a marketing instrument efficient in differentiating the rural touristic destinations. A special place in the development of the traditional cuisine is represented by the setting up and the promotion of the short food supply chains which can be achieved by sustaining the small local producers and by putting into practice an environment-friendly traditional agriculture. Sustaining the partnerships between the owners of accommodation units and the small local agricultural producers represents an essential element in putting into practice a sustainable and qualitative rural tourism. Romania has a substantial potential as regards the enhancement of short food supply chains thanks to: the large number of semi-subsistence agricultural farms (with an area under 5 hectares), the „village-town connection” as regards the food procurement, especially from acquaintances and relatives and the carrying on of a traditional agriculture at a large scale in the rural households.The case studies emphasized in the current paper (Harghita and Neamţ Counties) focus on the existence of short food supply chains, functional in the rural tourism sector under very different ways: touristic sheepfolds, trout farms, inns, authentic holiday villages, peasant guest houses etc

A Comparative Approach of Degradative Potential of Two Different Nanophotocatalysts onto a Model Textile Dye

Motivations and objectives. It is quite a difficult issue to treat, decolorize and mineralize textile dye waste containing dyes by conventional chemical methods (primary: adsorption, flocculation and secondary: chlorination, ozonization. It has been demonstrated that semiconductor photocatalytic oxidation of organic substances can be an alternative to conventional methods of removal of organic pollutants from water [1]. Advanced oxidation processes (AOPs) employing heterogeneous catalysis have emerged as a potentially destructive technology leading to the total mineralization of most of organic pollutants. An additional advantage of the photocatalytic process is its mild operating conditions and the fact the semiconductor can be activated by sunlight (near UV), thus reducing significantly the electric power requirement and hence the operating cost [2]. The main result and characterizing aspect of the research consist of the effectiveness of a semiconductor photocatalytic treatment of synthetic wastewater. Nanophotocatalysts ZnO have been successfully grown by hydrothermal method, onto some fibrous supports previously functionalized (grafted with MCT (monochlorotriazinyl-β-cyclodextrin, MCT-β-CD). The synthesis is reported elsewhere. The hydrothermal synthesis was performed using two types of surfactants widely used in nanoparticles preparation: Pluronic P123(triblock copolymer) and CTAB (cetyltrimethylammonium bromide). The novelty of the study consists in using these two different surfactants in growning of ZnO onto the fibrous supports. For degradation of Erionyl Roth dye, batch experiments were performed by irradiating the aqueous solution of model textile dye, containing ZnO nanocoated fibrous supports as semiconductor, in the presence of UV light. The photocatalytic process occurs under the illumination of an UV lamp, emitting light at wavelength 365 nm. The rate of decolorization was estimated spectrophotometrically from residual concentrations. Results and discussion. The enhancement of the photocatalytic activity is attributed to the CTAB. The performance of the photocatalytic system indicated that the photodegradation of the Erionyl Roth, in the presence of CTAB, occured with a 20 % reduction of time, compared to P123.The study has demonstrated that using the semiconductor performed by CTAB on the ZnO nano-oxides synthesized onto previously MCT grafted fibrous supports is effective in degradation of dyes as well as in the treatment of textile dye waste

Socio-economic impact of ecological agriculture at the territorial level

This deliverable investigates the socio-economic effects of ecological approaches to farming through implementing two participatory approaches, namely Delphi exercise and Q-method, at the level of a case study area (CSA). The focus is on how people and other productive assets are employed and remunerated by ecological approaches to agriculture, particularly those aspects that can influence employment, and drive the prosperity and vitality of local communities and some rural businesses. It is based on the collaborative research on Task 4.2 ‘Socio-economic impact of ecological agriculture at the territorial level’ of the LIFT project between UNIKENT (United Kingdom-UK) (Task Leader), BOKU (Austria), INRAE (France), VetAgro Sup (France), DEMETER (Greece), MTA KRTK (Hungary), UNIBO (Italy), IRWiR PAN (Poland), IAE-AR (Romania), SLU (Sweden), SRUC (UK). Beginning with the Delphi exercise, this deliverable presents qualitative information extracted from stakeholders in the following four steps. First, the researchers build a presentation of differences between ecological and conventional farming approaches in each CSA. Second, stakeholders elaborate on how they understand ecological farming approaches to exist in each CSA. Third, stakeholders develop a scenario of adoption of ecological approaches to farming depending on two factors: pattern (ecological farms forming clusters or randomly spread within the territory) and rate of adoption 10 years in the future. After establishing this scenario across two rounds, the stakeholders explore the socio-economic effects of their adoption scenario. The Q-methodology then presents a Q-set of statements that the Delphi has developed and, through factor analysis,studies the key stakeholder perspectives of the socio-economic effects of the perceived adoption of ecological practices in 10 years in the future. Four key results can be derived from the Delphi exercise and the Q-methodology. First, a higher adoption of ecological farming approaches, especially so at a 50% adoption rate, is mostly thought by stakeholders in the Delphi Exercise to lead to an increase in skill level and quality of life in on-farm employment. This is as a result of an increased diversity of farming enterprises on farms using ecological farming approaches, the interest generated from this, the knowledge of natural processes and biology required, engagement with nature and change in machinery that is coming into the industry. Strongly related to this need for skills is a predicted increase in the number of advisers and civil servants to deal with more complicated farms and incentives as well as monitoring of ecological effects on farm. An increase in required skill level is repeated across all Q-studies. Second, especially where farms are clustered together, Delphi Exercise respondents predict an increase in the trade of inputs such as manure and compost replacing synthetic fertiliser, as well as more sharing of capital and labour. Q-methodology highlights that these clusters may support a stronger social movement, more consumers buying local food and increase collaboration between farmers. Supply chains are expected to become shorter as farmers sell more directly and there are fewer intermediaries upstream of the farming sector. As farmers collaborate more with each other on environmental objectives, trading inputs and sharing best practices, farmer relationships should improve in rural communities. Third, Delphi exercise finds that contracting, machinery purchasers, and machinery traders and dealers could increase, decrease or display no change – the anticipated effects are mixed. Stakeholders are in no doubt that machinery use will change and therefore new skills will need to be learnt, but the wider effect on machinery purchase is uncertain. However, stakeholders conclude that a greater specialisation in machinery will occur leading to changes in farm management as well as the suppliers of this machinery. Q-methodology highlights that ecological practices will not mean the end of machinery and a lot more labour – often machinery will be useful in weeding and reducing physical labour as technology has significantly improved and skills are improving too in order to use these technologies. Fourth, Delphi respondents argued that although rural populations might be little affected by ecological farming, a shift in people moving from urban to rural settlements, and thereby a higher rural population density, seeking a more attractive rural environment, might contribute to higher local consumer demand. The Q-methodology highlights that where there is high adoption, rural areas are expected to become more attractive, as landscapes will have a much greater variety of crops instead of fields of monocrops. This variety of crops may include agroforestry (farmers interested in ecological approaches to farming may also be interested in agroforestry as a way of boosting their yields and protecting crops and livestock from the elements) as well as intercropping

Increasing community social capital in north-eastern rural Romania

The aim of this paper is to present tangible forms of knowledge generated by analyzing regional/local experiences, during more than ten years of synergetic cooperation between scientific researchers and public consultants in providing “public goods” for rural development in Romania. In this regards, the article contains a theoretical approach of the key concepts and a practical approach referring to the major steps undertaken in order to adjust, at least locally, the “classical triangle” to the new rural paradigm

Multidrug-Resistant (MDR) Urinary Tract Infections Associated with Gut Microbiota in CoV and Non-CoV Patients in a Urological Clinic during the Pandemic: A Single Center Experience

The aim of the study was to compare the profile of COVID-19 (CoV)-infected patients with non-COVID-19 (non-CoV) patients who presented with a multidrug-resistant urinary tract infection (MDR UTI) associated with gut microbiota, as well as analyze the risk factors for their occurrence, the types of bacteria involved, and their spectrum of sensitivity. Methods: We conducted a case–control study on patients admitted to the urology clinic of the “Parhon” Teaching Hospital in Iasi, Romania, between March 2020 and August 2022. The study group consisted of 22 CoV patients with MDR urinary infections associated with gut microbiota. For the control group, 66 non-CoV patients who developed MDR urinary infections associated with gut microbiota were selected. Electronic medical records were analyzed to determine demographics, characteristics, and risk factors. The types of urinary tract bacteria involved in the occurrence of MDR urinary infections and their sensitivity spectrum were also analyzed. Results: Patients in both groups studied were over 60 years of age, with no differences in gender, environment of origin, and rate of comorbidities. Patients in the CoV group had a higher percentage of urosepsis (54.5% versus 21.2%, p p p > 0.05), antibiotic therapy (77.3% versus 87.9%, p > 0.05), and the presence of permanent urinary catheters (77.27% versus 84.85%, p > 0.05). Escherichia coli (31.8% versus 42.4%, p > 0.05), Klebsiella spp. (22.7% versus 34.8%, p > 0.05), and Pseudomonas aeruginosa (27.3% versus 9.1%, p > 0.05) were the most common urinary tract bacteria found in the etiology of MDR urinary infections in CoV and non-CoV patients. A high percentage of the involved MDR urinary tract bacteria were resistant to quinolones (71.4–76.2% versus 80.3–82%, p > 0.05) and cephalosporins (61.9–81% versus 63.9–83.6%, p > 0.05), both in CoV and non-CoV patients. Conclusions: Patients with urological interventions who remain on indwelling urinary catheters are at an increased risk of developing MDR urinary infections associated with gut microbiota resistant to quinolones and cephalosporins. Patients with MDR UTIs who have CoV-associated symptoms seem to have a higher rate of urosepsis and a longer hospitalization length

Assessment of the Geographic Origin of Romanian Common Bean (<i>Phaseolus vulgaris</i> L.) Landraces Using Molecular Markers and Morphological Traits

The extreme weather that humanity has been confronting in recent years is the result of climate change. All over the world, unknown plant species are disappearing daily, which humankind has not discovered and will never know. Since 1900, the angiosperms and gymnosperms have been disappearing at a frequency of three species per year, but it is worrying that this rate of disappearance is up to 500 times higher currently. These data, correlated with the information provided by the United Nations (the world population will reach 10 billion by the year 2050) and FAO (food insecurity and the decrease of feedstock) lead to a crucial need to conserve and study plant germplasm. Therefore, plant germplasm conserved, especially in gene banks, can represent an important source for the development of varieties with an increased resistance to abiotic stress factors. Considering the origin of the current species of Phaseolus vulgaris L. as being in two distinct centers with different gene pools (Andean and Mesoamerica), the aim of the article is to infer the ancestry of 27 landraces according to their sampling geographical origin and morphological and molecular traits based on DNA sequences of three genes associated with abiotic stress tolerance (drought and thermal stress): PvREB5A, PvDREB6B, and PvRPS4. Phaseolus vulgaris L. has two different centers of origin: the Mesoamerican and the Andean basins. In this research, 27 landraces were evaluated from different counties in Romania. Three genes, PvREB5A, PvDREB6B, and PvRPS4, were amplified by the PCR reaction, sequenced by the Sanger technique, and the data obtained were analyzed using MEGA XI software. For morphological data, the GraphPad Prism 9 software was used. According to PvDREB5A, 81.5% of all studied landraces belong to the Mesoamerican gene pool and 18.5% belong to the Andean. PvDREB6B revealed a high nucleotide and amino acid diversity between the Andean and Mesoamerican genotypes compared to the other evaluated genes. Also, the PvRPS4 gene from the chloroplast genome showed one SNP within its coding region, different for those two gene pools, which is directly involved in a nonsynonymous substitution. The morphological characteristics, such as weight for 100 seeds, length, height, width, weight, seed flatness, flatness index, seed elongation, and eccentricity index were determined. European landraces of Mesoamerican origin indicated a large seed size compared to Andean genotypes. This work can be a foundation for the identification of interesting traits that establish plant adaptation to abiotic stress and conserve landraces of common beans from genetic depletion

Experimental And Theoretical Insight Into Formulations Based On Poly(Vinyl Alcohol Boric Acid) And Diclofenac Sodium Salt

A series of three formulations were prepared in view of experimental and theoretical investigation of their drug release potential. The morphology of the film formulations, in terms of distribution of drug into the polymeric matrix and the nature of the drug was investigated by scanning electron microscopy and polarized light microscopy techniques. The in vitro drug release has been studied in a medium mimicking the physiological medium. It was established that the drug release is in close correlation with the mass ratio. Assuming that the dynamics of polymer-drug system's structural units take place on continuous and nondifferentiable curves (multifractal curves), we show that in a one-dimensional hydrodynamic formalism of multifractal variables the drug release mechanism (Fickian diffusion, non-Fickian diffusion, etc) are given through synchronous dynamics at a differentiable and non-differentiable scale resolutions. Finally, the model is confirmed by the empirical data
