- Abstract:
- ... Nopol is a fine chemical obtained from Prins reaction between β-pinene that is a pine derivative and paraformaldehyde; this alcohol has several applications in the aromas and fragrances industry, agrochemicals, pharmaceuticals and household products. The current knowledge gap with this contribution is evaluate the environmental impacts of nopol synthesis by two alternative processes using the Life ...

- Abstract:
- ... Battery electric vehicles do not emit CO₂ from an internal combustion engine but can cause emissions while charging electricity generated by remote fossil power plants. Smart charging offers the possibility to reduce carbon dioxide emissions (CO₂) by shifting the charging sessions to moments with lower emissions in power generation. However, this requires the battery electric vehicle user to accep ...

- Abstract:
- ... Bioethanol from cassava pulp is a value-added alternative for cassava pulp management and reduces the environmental impact of cassava processing. Using life cycle assessment, this study aims to evaluate the environmental performance of ethanol produced from cassava pulp and it’s use as transport fuel. The results showed that the best-case scenario is the ethanol factory that fully utilizes a bioga ...

In this formation, we recognize five facies (pebbly sandstone, intensely bioturbated sandstone, medium- to coarse-grained cross-stratified sandstone, fine-grained sandstone, and planar laminated siltstone), assigned to two f ...

Phasmatodea species diversity lies almost entirely within its suborder Euphasmatodea, which exhibits a pantropical distribution and is considered to derive from a recent and rapid evolutionary radiation. To shed light on Euphasmatodea origins and diversification, we assembled the mitogenomes of 17 species from transcriptomic sequencing data and analysed them along with 22 already available Phasmat ...

- Abstract:
- ... How plant seeds originated remains unresolved, in part due to disconnects between fossil intermediates and developmental genetics in extant species. The Carboniferous fossil Genomosperma is considered among the most primitive known seeds, with highly lobed integument and exposed nucellus. We have used this key fossil taxon to investigate the evolutionary origins of seed development. We examined se ...

However, this benefit was shown to be outweighed by the (attributional) life cycle impacts associated with mulch production. The current study expanded the scope of prior investigations to perform a consequential life cycle assessment of the i ...

Ancient proteomics is being applied to samples dating further and further back in time, with many palaeontological specimens providing protein sequence data for phylogenetic analysis as well as protein degradation studies. However, fossils are a precious material and proteomic analysis is destructive and costly. In this paper we consider three different techniques (ATR-FTIR, MALDI-ToF MS and chira ...

Our understanding regarding the onset and development of the modern South Asia monsoon (SAM) is still incomplete due to its complex nature and differing views about its relationship with major orographic features such as the Himalaya and Tibetan Plateau. Climate data derived from some terrestrial and marine sediments from the Neogene suggests the onset and intensification of the SAM to a near-mode ...

In this study, we investigate the tracheal systems of five different scutigeromorph species. They are strikingly similar to each other but depict unique characters compared to the tracheal systems of pleurostigmophoran centipedes, which has engendered an ongoing debate o ...

These studies paid little attention to fossils, using them only as dating tools. The identification of Elateridae fossils is challenging, as external synapomorphies are not known for this family. Elateridae can be ...

Bone-gnawing scavengers modify proboscidean carcasses and individual bones in patterned sequences. We summarize how scavengers modify major skeletal elements in stages which may reflect the extent of carcass utilization. The stages of modifica ...

The chemostratigraphic record of the Toarcian Oceanic Anoxic Event (T-OAE) is generally well documented in epicontinental basins; however, the duration of anoxia and recovery remains poorly constrained in the Tethys Ocean owing to limited stratigraphic resolution of oceanic sections with hiatuses. In this paper, we describe a relatively continuous hemipelagic record in the Central Western Carpathi ...
