The Vertical Olive Crushing Mill as a Machine and its Energy Balance - A Preliminary Approach

open access: yesEXARC Journal, 2020
The vertical crushing mill turns the olives into pulp by combining the rotational and rolling motion of a heavy upright stone wheel that moves with continuous contact along a circular horizontal trajectory on a stationary base which forms the system's ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Re-Creating an Aboriginal Earth Oven with Clayey Heating Elements: Experimental Archaeology and Paleodietary Implications

open access: yesEXARC Journal, 2018
Earth ovens may relate to different ancestral cooking techniques, serving specific needs and functions. In eastern and south-eastern Australia, they were a significant element of a thriving pre-colonial Aboriginal culture.

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Naval Engineering and Labor Specialization during the Industrial Revolution [PDF]

open access: yes
This paper explores the roles of capital- and technology-skill complementarities in labor allocation decisions within the U.S. Navy. During the latter 19th century the ocer corps was highly specialized, and was split between groups of line and sta ocers.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Towards Understanding the Politics of Flex Crops and Commodities: Implications for Research and Policy Advocacy [PDF]

open access: yes, 2014
This discussion paper offers a preliminary exploration of the concept and phenomenon of “flex crops and commodities”, building on an earlier and initial analysis and abbreviated idea put forward by some of the authors of this paper.
