This article aims to identify the obstacles entry and permanence of peasant women in Licentiate Degree Countryside Education, at Senador Helvídio Nunes de Barros Campus, Federal University Piauí. In this qualitative research, interviews were carried out, conducted through a semi-structured questionnaire, with five students course. The interviewees reported as limiting factors for both admission...
Soil texture has been commonly associated with the population density of Heterodera glycines (soybean cyst nematode: SCN), but such an association has been mainly described in terms of textural classes. In this study, multivariate analysis and a generalized linear modeling approach were used to elucidate the quantitative relationship of soil texture with the observed SCN population density redu...
This paper presents a case study of several DNAPL contaminated sites around the Severn Estuary (UK) where a combination of detailed observations, core dissections and physicochemical characterisation of alluvial clay–silt horizons have revealed the presence of fossil rootlet biopores which act and have the potential to act as conduits for contaminant migration through up to 13 m of clay–silt. T...
The capital city in Mongolia comprises two types of dwellings: apartments and Gers. Ger is a traditional Mongolian house. Residents districts Ulaanbaatar use coal as source fuel for daily activities such heating cooking winter due to lack central systems. After burning, the ash deposited at bottom oven converts into powder containing heavy metals that are toxic human health. Through questionnai...
Dockless bicycle sharing is one of the low-carbon transportation modes towards sustainable mobilities. Electric fences, as an effective solution for parking management, may have a high potential in guiding usage dockless bicycles at low operation cost. However, new issues arise with implementation electric fences. The location fences hotspots fails to match demand, leading congestion urban cent...
In some situations, dams need to be built on non-rock alluvial grounds such as sand and sand-silt deposits. Therefore, undrained behavior and strength of silty sands are of great importance. One of the critical factors in studying the behavior of sand-silt mixtures is inherent anisotropy, a natural soil characteristic that depends on its texture and is independent of the soil's initial stress s...
The effects of various growing substrates, combinations of soil, silt, sand, press mud (PM) and rice hulls (RH) on plant growth, yield and quality of rose (Rosa hybrida L.) cvs. Kardinal, Anjlique and Gold Medal, were studied to standardize substrates for cut rose production and develop better management and quality production protocol. Plant height, number of leaves branch, leaf area, number o...
