MADFORWATER. WP4 Field pilots for the adaptation and integration of technologies. Task4.3 Operation and optimization of the field pilots. Wastewater treatment performances and Irrigation/treated wastewater reuse performances. Municipal wastewater pilot. UMA-Tunisia
No full textThis dataset contains the data produced by UMA team in the framework of task 4.3 of MADFORWATER project. Two sets of data were generated during the first and the second periods of survey of the pilot to evaluate: (i) the Municipal Wastewater Treatment Pilot efficiency, and (ii) the impact of the Treated Municipal Wastewater (TMWW) reuse in agriculture.
The first part of the data consists of quantitative survey results from monitoring the Pilot at different sampling points, including SP1: pilot plant inlet, sampling point after preliminary treatments in the main WWTP, SP2: outlet of the BOD oxidation section, SP3: outlet of the nitrification section and SP4: sample point after disinfection and secondary settler, constructed wetland (CW) inlet and SP5: sample after the constructed wetland. The monitored physicochemical parameters are: chemical oxygen demand (COD), Biochemical oxygen demand (BOD), Total Suspended Solids (TSS), the conductivity, the turbidity, Kjeldahl Nitrogen (NKj), nitrite (NO2), nitrate (NO3), ammonium (NH4), phosphate (PO4) and Total Phosphorous (TP), pH, Temperature and Dissolved Oxygen, E. coli.
The second part of the data consist of the irrigation pilot reports on the performance of the Treated Municipal Wastewater (TMWW) reuse in agriculture. The supply of Plant Growth Promoting (PGP) bacteria through irrigation network was also investigated. A first-year corn field trial allowed the evaluation of the plant growth and crop production including roots and shoots fresh and dry weights, plant height, tassel length, plant and ear numbers, grain number, crop yield, crop biomass and 100-grain weight. The second-year field trial on wheat crop estimated the effect of TMWW and PGPB supply on shoot and spike lengths; root, shoot and spike weights; and wheat crop biomass. Data related to crop water productivity and soil microbiological quality are also reported for both crop types (Maize and Wheat)
Fuzzy poverty measurement: multidimensional and unidimensional indicators
Get PDFThis paper proposes a comparison between multidimensional and unidimensional poverty indicators. Sets of poor units identified by traditional head count ratio, fuzzy unidimensional and fuzzy multidimensional indices are compared by means of a rank correlation analysis. The robustness of the comparison is ensured by a simulation study, which allows to address several issues related not only to fuzzy sets based methods, such as the subjective choice of membership to the poor set, but also to the multidimensional measurement, such as the effect of the weighting system. Our results stress that the unidimensional indicators provide partial information on poverty condition
OLEUM project. Revised method for determination of fatty acid ethyl esters in virgin olive oils. Data from in-house validation
No full textThis data set contains the underlying data of the scientific publication:
Palagano, R.; Valli, E.; Tura, M.; Cevoli, C.; Pérez-Camino, M.C.; Moreda, W.; Bendini, A.; Gallina Toschi, T. Fatty Acid Ethyl Esters in Virgin Olive Oils: In-House Validation of a Revised Method. Foods 2020, 9(7), 924; https://doi.org/10.3390/foods9070924.
The content of fatty acid ethyl esters (FAEEs) is one of the quality parameters to define if an olive oil can be classified as extra virgin since these compounds are considered markers for virgin olive oils obtained from poor quality olives, but can be also indirect markers to detect soft deodorization treatment. The official protocol for determination (EU Reg. 61/2011) can be improved in terms of solvents amount and time of analysis.
An off-line HPLC-GC-FID method for FAEEs determination was developed, revising both the preparative step and the GC injector required by the official method. After optimization, the method was in-house validated by analyzing several parameters (linearity, LOD, LOQ, robustness, recovery, precision and accuracy). This data set contains the in-house validation results obtained

Lavoro e salute. Trenta anni dalla direttiva 89/391/CEE
Get PDFThe year 2019 marked the thirtieth anniversary of the directive 89/391/EEC concerning the introduction of measures to encourage improvements in the safety and health of workers at work. This ebook proposes a discussion on the effects of the directive and the adoption of its provisions, also in light of the new challenges associated with the evolution of human work. Are the principles laid down by directive 89/391 still relevant, 30 years later? Moreover, how to evaluate the national regulations that have been brought into force basing on the principles laid down by the directive? Has the current regulation on health and safety at work achieved a level of sophistication and consistency adequate to effectively pursue its objectives
Contrasting EMI lecturers’ perceptions with practices at the University of Bologna
Get PDFEnglish-Medium Instruction (EMI) is rapidly being taken up in universities worldwide, though the
speed at which EMI courses are appearing continues to outpace empirical research (Martín del Pozo
2017). In this context, research has primarily provided insights on lecturers’ self-perceptions, by
prioritizing lecturers’ need for training in EMI. Our contribution here is threefold. First, we aim to
provide an account of lecturers’ self-perceptions of their own teaching in English, resulting from a
survey involving 40 EMI lecturers in Engineering and Economics at the University of Bologna.
Second, by cross-referencing their replies with relevant literature, we aim to identify recurring
patterns in lecturers’ self-perceptions. Third, by cross-referencing these perceptions with findings
from lecture recordings, we aim to determine how far lecturers’ assumptions are consistent with
their classroom practices. Results show that experienced EMI lecturers are able to identify three
main dimensions of EMI: academic English proficiency, instructional style, and “culturally shaped
norms of teacher-student interactions” (Hu and Li 2017: 200). However, contrasting lecturers’
perceptions with what they actually do in the classroom has proved that the intentions and strategies
of lecturers need to be acted upon before substantial improvements in their approach to teaching can
be expected. Implications for providing lecturer-support programs are discussed
OLEUM project. Rapid screening tool of quality grades of virgin olive oils. FGC in tandem with chemometrics
No full textThis data set contains the underlying data of the scientific publication:
Barbieri S. et al., 2020. FGC in tandem with chemometrics: a rapid screening tool of quality grades of virgin olive oils.
This publication will be submitted to a scientific journal.
This research aims to develop a classification model based on an untargeted elaboration of volatile fraction fingerprints of virgin olive oils (n=331) analyzed by Flash Gas-Chromatography in order to predict the commercial category of samples (extra virgin olive oil, EVOO; virgin olive oil, VOO; lampante olive oil, LOO). The raw data related to volatile profiles were considered as independent variables, while the quality grades provided by the sensory assessment were defined as reference parameter. This data matrix was elaborated using a linear technique, Partial Least Squares-Discriminant Analysis (PLS-DA), applying, in sequence, two classification models with two categories (EVOO vs noEVOO followed by VOO vs LOO and LOO vs noLOO followed by VOO vs EVOO). Results from this large set of samples provide satisfactory results in terms of percentages of correctly classified samples, ranging from 72 to 85%, in external validation. This confirms the reliability of this approach as rapid screening of quality grades and that it represents a solution for supporting the sensory panels, increasing the efficiency of the controls, applicable also to the industrial sector. This data set contains the raw data obtained from the analysis of all the sample by Flash Gas-Chromatography and used for the building of the PLS-DA data matrix
Measuring Global Macroeconomic Uncertainty
Get PDFThis paper provides new indices of global macroeconomic uncertainty and investigates the cross-country transmission of uncertainty using a global vector autoregressive (GVAR) model. The indices measure the dispersion of forecasts that results from parameter uncertainty in the GVAR. Relying on the error correction representation of the model, we distinguish between measures of short-run and long-run uncertainty. Over the period 2000Q1-2016Q4, global short-run macroeconomic uncertainty strongly co-moves with financial market volatility, while long-run uncertainty is more highly correlated with economic policy uncertainty. We quantify global spillover effects by decomposing uncertainty into the contributions from individual countries. On average, over 40% of country-specific uncertainty is of foreign origin
Reference price effect on consumer choice in online and traditional supermarkets: An application of discrete choice model on home scan data
Get PDFReference price effect on consumer choices is an acknowledged phenomenon in marketing literature. Several studies have explored this issue using both observational studies and choice experiments. Furthermore, evidence exists on different consumer behaviour when shopping in traditional stores and online. Hence, question arises on whether and how consumers take into account reference price when shopping online. This study aims to analyze and compare consumer behaviour in online stores and traditional stores. A definition of reference price based on past prices is adopted and a discrete choice model is proposed, which includes gain and losses as additional product attributes, with individual-specific coefficients. The model is applied on observed cola purchases (home scan data) in traditional supermarkets and in an online store. Results indicate that loss aversion does play a role in online choices, but the effect is smaller if compared to choices in traditional stores
Integrated water & land management strategies and policy recommendations
Get PDFIt was found that in the Middle East and North Africa (MENA) region from climate-related water scarcity, greatest economic losses can be expected (World Bank 2018 in World Resources Institute 2019). Yet, here are unused opportunities to boost water security in MENA. Large amounts (about 82%) of the region’s wastewater is not reclaimed; meaning using this resource would produce a new and clean water resource (World Resources Institute, 2019).
The scope of the MADFORWATER project is to develop integrated technological and management solutions to boost wastewater treatment and an efficient reuse of treated wastewater for irrigation in selected hydrological basins in Egypt, Morocco and Tunisia.
In this deliverable 6.1 integrated water & land management strategies and policy recommendations were established. This was carried out in two main approaches: i) the integration and assessment of water & land management strategies, ii) policy recommendations to promote the adoption of the proposed technologies and integrated waster & land management strategies in the target countries
