Production and characterization of ecological fire starter from sawdust and vegetable oil.

The objective of this article aims to reduce indoor air pollution through the use of ecological fire starter (EFS) made from sawdust and vegetable oils. In the Far North region of Cameroon, plastic waste is used to ignite and stoke solid fuels fires, exposing mainly women and children who are responsible for cooking to health risks from indoor air pollution. Thus, the survey conducted among the population of the region shows that 96% of urban households use plastics waste made with LDPE, HDPE, PET, PS, PP and EVA as fire starter for solid fuels.

Accessibility and effects of binder types on the physical and energetic properties of ecological coal.

The objective of this paper was to determine the effects of binders on the physical and energetic properties of briquettes as well as their accessibility. Proximate analysis and investigation on binder cost on local market were conducted. The results show that the addition of binder increases the durability and density, but decreases the LHV of briquettes.

Estimating crop parameters using Sentinel-1 and 2 datasets and geospatial field data.

Crop monitoring is essential for ensuring food security in a global context of population growth and climate change. Satellite images are commonly used to estimate crop parameters over large areas, and the freely available Synthetic Aperture Radar (SAR) Sentinel-1 (S-1) and optical Sentinel-2 (S-2) images are relevant for that purpose combining high temporal resolution and high spatial resolution. For this data article, field surveys were conducted from January to July 2017 in France to sample wheat and rapeseed crop parameters during the entire crops cycle.

Short-Term Safety of the Direct Superior Approach for Total Hip Arthroplasty.

Introduction: Minimally invasive surgery total hip arthroplasty (MIS-THA) is becoming increasingly popular. There are several approaches to MIS-THA that vary according to anatomical access to the hip joint. The direct superior (DS) approach is a recent modification of an MIS posterior approach that spares the iliotibial band and most of the short external rotators of the hip, particularly the quadratus femoris.

Direct Superior Approach to the Hip for Total Hip Arthroplasty.

Background: Traditional posterior approaches to the hip, posterolateral and mini-posterior, violate the iliotibial band and the short external rotators, specifically the quadratus femoris and obturator externus muscles. The direct anterior approach does not violate the iliotibial band or the quadratus femoris, resulting in earlier ambulation and lower dislocation rates. The direct superior (DS) is a posterior approach that spares the iliotibial band, obturator externus tendon, and quadratus femoris muscle.
