Food Contaminants
2014
Chemical contaminants may occur in our food from various sources. Contaminants can be present in foods mainly as a result of the use of agrochemicals, such as residues of pesticides and veterinary drugs, contamination from environmental sources (water, air or soil pollution), cross-contamination or formation during food processing, migration from food packaging materials, presence or contamination by natural toxins or use of unapproved food additives and adulterants. They typically pose a health concern, resulting in strict regulations of their levels by national governments and internationally. Therefore, analysis of relevant chemical contaminants is an essential part of food safety testin…
Contribution to the Sustainability Challenges of the Food-Delivery Sector: Finding from the Deliveroo Italy Case Study
2020
The food delivery sector is assuming increasing importance in the distribution of food products and meals as it is becoming an ordinary component of consumption habits. However, the growth of the sector has inevitably affected the demand for freight transport, especially in urban areas. The aim of this study was to investigate the main enabling factors affecting the adoption of sustainable strategies, among which the electro-mobility, in the food delivery sector and what obstacles to dissemination can be seen. Deliveroo s.r.l. was chosen as case study. Results show that Deliveroo undoubtedly represents a good example of sustainable logistics and the dissemination of good practices among the…
Research focusing on plant performance in constructed wetlands and agronomic application of treated wastewater – A set of experimental studies in Sic…
2019
Constructed wetlands are sustainable technologies for the treatment of wastewater. These biological systems have been widely studied throughout the world for more than 30 years; however, most studies have focused on the effects of design and engineering on pollutant removal from wastewater. Undoubtedly, agro-technical aspects have been given too little consideration by research. This paper reports the main results of a set of experiments carried out on two pilot horizontal subsurface flow systems in Sicily (Italy). Festuca, Lolium and Pennisetum spp. in combination and three emergent macrophytes-Arundo donax L., Cyperus alternifolius L. and Typha latifolia L.-alone, were assessed. The aim o…
Latvijas mazumtirdzniecības uzņēmumu attīstības analīze
2016
Mazumtirdzniecības nozares un uzņēmumu attīstība ir būtiska valsts vai reģiona labklājības attīstībai. Palielinoties mazumtirgotāju konkurencei noteiktajā reģionā, pircējiem rodas iespēja iegūt izdevīgākus produktu cenu piedāvājumus, produktu sortimenta paplašinājumu un apkalpošanas kvalitātes paaugstinājumu. Tā kā šobrīd ir vērojams apkopotās informācijas par Latvijas mazumtirdzniecības nozares attīstības tendencēm un uzņēmumu ģeogrāfiskā attīstības potenciāla novērtēšanas metodoloģijas trūkums, maģistra darbs “Latvijas mazumtirdzniecības uzņēmumu attīstības analīze” ir izstrādāts ar mērķi izpētīt Latvijas pārtikas preču mazumtirdzniecības nozares attīstības tendences un novērtēt republika…
Impact of very low crop residues cover on wind erosion in the Sahel
2011
International audience; In the Sahel, with average annual precipitation in the order of 500 mm yr− 1, wind erosion occurs mainly on cultivated millet fields whose surfaces are only partially covered by crop residues. The impact of these residues on wind erosion was not clearly established. The objective of this study is thus to quantify the actual amount of crop residues in traditional Sahelian fields and to determine their impacts on wind erosion by reference to a bare surface throughout the seasonal cycle over several years. At the beginning of the year during dry season, Sahelian farmers use to "clean" their fields, i.e. cut and lay flat on the soil surface any millet stalks still standi…

Titre originel : Utilisation des pesticides : la nécessaire protection du voisinage – À travers l'annulation partielle de l'arrêté du 4 mai 2017 réglementant les conditions d'usage des produits phytosanitaires, le Conseil d'État intime l'ordre au pouvoir politique de prendre des mesures de protection du voisinage des cultures traitées.
Agronomy and climatology of a 100 000 km² watershed in West Africa.
2011
7 pages; International audience; Sahelian regions are considered as particularly vulnerable to climatic variability and change for two reasons: the dominant role of rainfed agriculture in their economies and their weakness of water resources management. The physiological response of an individual plant to the climatic variations of parameters is well documented, but extrapolation to regional food production still remains very dubious. On the Bani, a tributary of the Niger River in Mali, climatic variables representative of the agroclimatic constraints of the cultures (dynamics of the rainy season and occurrence of extreme events) were evaluated from observed past data and simulated future d…

Under actual conditions of agroecosystems and agrocoenosis of the forest-steppe zone of Ukraine, the use of neonicotinoids and synthetic pyrethroid insecticides in apple orchards pose no hazard to terrestrial ecosystems and human health in terms of nutrition hygiene and sanitary soil protection,provided that conventional technolo- gies as well as agrotechnical and hygienic regulations apply.
Magnaporthe oryzae as an expression host for the production of the unspecific peroxygenase AaeUPO from the basidiomycete Agrocybe aegerita.
2021
Abstract The filamentous fungus Magnaporthe oryzae has the potential to be developed as an alternative platform organism for the heterologous production of industrially important enzymes. M. oryzae is easy to handle, fast‐growing and unlike yeast, posttranslational modifications like N‐glycosylations are similar to the human organism. Here, we established M. oryzae as a host for the expression of the unspecific peroxygenase from the basidiomycete Agrocybe aegerita (AaeUPO). Note, UPOs are attractive biocatalysts for selective oxyfunctionalization of non‐activated carbon‐hydrogen bonds. To improve and simplify the isolation of AaeUPO in M. oryzae, we fused a Magnaporthe signal peptide for pr…
Crop type and altitude are the main drivers of species composition of arable weed vegetation in Tajikistan
2015
Summary The influence of broad-scale environmental factors on the species composition of segetal weed communities in Tajikistan was investigated. The research was conducted throughout the country, analysing plots of root crops as well as cereals from all phytogeographical regions of Tajikistan, with the exception of the eastern Pamir. The study was based on 440 phytosociological relevees sampled between 2009 and 2013 and analysed using direct and indirect ordinations. A set of environmental variables was obtained for each plot: altitude, mean annual precipitation, mean annual temperature, pH, crop type, longitude, latitude and date of sampling (seasonality). Crop type was the major factor d…
