Abstract:
... This paper assesses the feasibility of producing a metallurgical quality charcoal (biocoke) through slow high temperature pyrolysis of woody biomass. The samples used for the experiments were different types of olive wood biomass from southern Spain as well as eucalyptus trunks from Uruguay. The experiments were conducted in a two-step process: a pyrolysis semi-batch reaction at 750 °C and 3 °C/mi ...

Abstract:
... The study of the genotype×environment interaction is a prominent issue, requiring care for recommending improved superior genotypes to certain areas. Experimentally, it is possible to infer that the puzzle of genotype recommendations relies on edaphic and climatic changes over different terrain latitudes and longitudes, and further fluctuates in microenvironments as a result of site variations.

Eucalyptus; biomass; carbon dioxide; carbon monoxide; carbonization; catalysts; charcoal; fuels; greenhouse effect; greenhouse gas emissions; hydrogen; industry; methane; nickel; pyrolysis; reducing agents; steam; wood; zeolites
Abstract:
... The metallurgical industry uses fossil carbonaceous materials in order to fulfill the high energetic demand of its processes, involving the emission of great amounts of CO2 that contribute to the greenhouse effect. These CO2 emissions can be mitigated by using biomass derived fuels and products due to their CO2-neutral condition. The objective of this paper is to study the carbonization process of ...

Abstract:
... Mining activities can increase the mobility of metals by accelerating the dissolution and leaching of minerals from the rocks and tailing piles to the environment and, consequently, their availability for plants and subsequent transfer to the food chain. The weathering of minerals and the disposal of coal waste in tailing piles can accelerate the generation of acid mine drainage (AMD), which is re ...

Abstract:
... Analysing the pollen stored by stingless bees allows identification of the diversity of flowering plants visited by these bees while collecting resources during a given period. However, few studies have focused on investigating the sharing of resources between species of native bees that coexist in transitional plant formations, which support conservation efforts and increase colony productivity. ...

Abstract:
... Eucalyptus dieback is a physiological disorder characterized by lesions on the apex of the branches and the death of the shoot apex. Some clones are considered tolerant to this disorder, although, up to now, there are no reports on the use of phenotypic markers for selecting tolerant material. The use of phenotypic markers may contribute to an efficient selection, where the estimation of genetic p ...

Abstract:
... Although genome‐wide association studies (GWAS) have provided valuable insights into the decoding of the relationships between sequence variation and complex phenotypes, they have explained little heritability. Regional heritability mapping (RHM) provides heritability estimates for genomic segments containing both common and rare allelic effects that individually contribute too little variance to ...

Abstract:
... The eucalyptus leaves generated by the forestry plantations in Mexico represent a neglected biomass residual resource that has a potential for the extraction of essential oil and would allow achieving economic incomes, as well as employment in the forestry sector. Its revalorization as raw material to extract essential oil constitutes a sustainable method that adds it value. Likewise, it contribut ...
