An experiment was set up in dispersed blocks design where each producer constituted a repetition. Fertilizers were applied using the microdose technique. The results showed that the best grain yields of sorghum are obtained with the technology combining stone bunds + zaï + NPK + urea with respectively 1428.70 kg / ha in 2018 and 1158.40 kg / ha in 2019.

Nesting of dabbling ducks was studied in 1983 and 1984 on a southern Quebec marsh. Nest locations were determined during the nesting period in all habitats of the marsh (926 ha) and in a sample representing 24.4% (284 ha) of the fields available for nesting in the neighbouring agricultural zone. A total of 115 nests were numbered, involving mainly Mallards (Anas platyrinchos) and Blue-winged Teals (Anas discors). In the agricultural zone, nesting grounds were used mainly by the teals. However, 62% of the nests were destroyed during the first haying. Although mallards usually nest on the ground

Currently, special attention is paid to improving the production technology of synthetic rubbers. Synthetic rubbers are in great demand in the tire and rubber industry, in the manufacture of composite materials for various purposes, etc. Every year, the requirements for both the quality of manufactured products and the environmental friendliness of their production are increasing. One of the problematic stages in the production of rubbers by emulsion polymerization is the stage of their separation from latex.

AbstractThe ecological effects of disrupted flooding are known to be pernicious for the occurring riparian fauna. As flooding disturbance is argued to structure species assemblages, behavioural aspects may be affected just as well. Generally, eurytopic inhabitants possess a well-developed dispersal ability allowing frequent recolonization, whereas specialized stenotopic species are expected to be adapted to these stress regimes. This study aims at determining whether flooding induces different behavioural responses in two congeneric wolf spider species. Variation in flood-avoiding behaviour wa

The Renaissance treatise De Re Metallica (Georgius Agricola, 1556) is one of the first works that deals in detail with the state of the art of metal mining, compiling the main techniques and mechanical devices used in this industrial activity at that time. An advanced knowledge of the human–machine set is observed in this treatise, from a mechanical and ergonomics point of view. The main objective of this work is to carry out an ergonomics analysis of one of the mechanical devices collected in the sixth book of this treatise.

During field surveys in February and March of 2007 and 2008, unusual symptoms of wilting were observed on squash plants (Cucurbita pepo L.) cultivated near Fondi (Latium-Central Italy) in two commercial plastichouses. Because of the high incidence of the disease (between 20 and 30%), we performed specific diagnostic assays. Symptoms included yellowing, stunting, vascular discoloration, and premature death of leaves. A fungus was consistently isolated on potato dextrose agar (PDA) from discolored vascular tissues in the stems. On the basis of fungal morphology (one-celled conidia, 1 to 2 μm in
