Invasive Alien Plants in Sub-Saharan Africa: A Review and Synthesis of Their Insecticidal Activities
2021
Despite the cornucopia of agricultural, economic and ecological ramifications of invasive alien plant species (IAPs) in sub-Saharan Africa, studies on their potential use as bio-insecticides have not received adequate attention compared to the burgeoning plethora of literature on their use in ethnomedicine. In the current study, we review the existing, but scattered literature on the insecticidal activity of different parts of some IAPs; specifically those invasive in sub-Saharan Africa but with published literature from Africa and elsewhere. From our literature survey, we found that 69 studies from four continents (Africa, Asia, North America and South America) reported the insecticidal ac…
Diversity of the selected elements of agricultural potential in the European Union countries
2020
Agricultural importance in determining the directions of respective regions results from its production potential. The agricultural potential of a given country is determined by natural resources, ways of using them, natural conditions, workforce resources, technical resources and basic economic conditions. In this paper, only income and rural population are taken under consideration to describe the agricultural potential. Currently, European Union countries are functioning under the assumptions of the Common Agricultural Policy, assuming, among other things, increasing agricultural productivity, ensuring an adequate standard of living for the rural population and stabilising markets. The E…
Production et commerce, quelques aspects dans le nord de la Gaule romaine (Ier-IIIe siècle de notre ère)
2023
L’étude de l’économie de la Gaule romaine par les archéologues a traditionnellement privilégié l’analyse des lieux de production agricole et artisanale, ainsi que la diffusion des produits manufacturés. La large diffusion de produits à l’échelle du bassin méditerranéen et jusque dans les provinces septentrionales de l’Empire, voire en dehors, suggère une économie ouverte aux échanges à longue distance. Les recherches montrent cependant que la diffusion n’atteint jamais la totalité de l’Empire, voire du Bassin méditerranéen, si ce n’est de manière marginale. Par ailleurs, à l’écart des rivages de la Méditerranée, l’examen des mobiliers provenant de sites d’habitat conduit à nuancer la place …
Ecological risk assessment of pesticides in the Mijares River (eastern Spain) impacted by citrus production using wide-scope screening and target qua…
2021
The widespread use of pesticides, especially in agricultural areas, makes necessary to control their presence in surrounding surface waters. The current study was designed to investigate the occurrence and ecological risks of pesticides and their transformation products in a Mediterranean river basin impacted by citrus agricultural production. Nineteen sites were monitored in three campaigns distributed over three different seasons. After a qualitative screening, 24 compounds was selected for subsequent quantitative analysis. As expected, the lower section of the river was most contaminated, with total concentration >5 µg/L in two sites near to the discharge area of wastewater treatment pla…
Latvijas Universitātes kultūrvēsturiskais mantojums izstādēs: Bibliotēkas versija
2020
Bibliotēka kā atmiņas institūcija ir atbildīga par savas ‘jumta organizācijas’ kultūrvēsturiskā mantojuma saglabāšanu un pieejamību sabiedrībai. Latvijas Universitātes Bibliotēkas rūpju lokā ir ne tikai LU informacionālais nodrošinājums ikdienā, bet arī pašas Universitātes intelektuālais, zinātniskais un kultūras mantojums ilglaicīgā aspektā. Ar iespējami pilnīgāku ar Universitāti, tās darbību un cilvēkiem saistītu materiālu uzkrāšanu ir par maz, tie ir arī jāapkopo, jāsistematizē, jāapstrādā, jādara pieejami un visbeidzot - jāpopularizē, lai informācija nonāktu apritē un pavērtu iespējas tā tālākai izmantošanai, izpētei, zināšanai, nevis iegultu putekļos. Bibliotēkas devums, kāds pirms pār…
Valorization of kiwi agricultural waste and industry by-products by recovering bioactive compounds and applications as food additives : a circular ec…
2021
Currently, agricultural production generates large amounts of organic waste, both from the maintenance of farms and crops (agricultural wastes) and from the industrialization of the product (food industry waste). In the case of Actinidia cultivation, agricultural waste groups together leaves, flowers, stems and roots while food industry by-products are represented by discarded fruits, skin and seeds. All these matrices are now underexploited and so, they can be revalued as a natural source of ingredients to be applied in food, cosmetic or pharmaceutical industries. Kiwifruit composition (phenolic compounds, volatile compounds, vitamins, minerals, dietary fiber, etc.) is an outstanding basis…
Solis uz priekšu Frankofonijas kultūras zināšanu izplatībā Latvijā
2017
Latvijas Universitāte stiprinās sadarbību ar Franciju pētnieciskajā, izglītības un kultūras jomā. Savstarpējā sadarbība ir liels solis uz priekšu, lai Latvijā vēl vairāk izplatītu Frankofonijas kultūras zināšanas, attīstītu pētniecības un sociālos jautājumus.
Optimal Solutions for the Use of Sewage Sludge on Agricultural Lands
2021
The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were …
