Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

Assessment of Mechanical Properties of Concrete by Combining Digital Image Correlation and Ultrasonic Pulse Velocity

open access: yesBuildings
The ultrasonic pulse velocity (UPV) method is widely used for determining the dynamic modulus of elasticity of concrete. Traditionally, this approach requires assuming Poisson’s ratio (arbitrary values ranging from 0.1 to 0.25), regardless of the actual ...

The Business Cycle, Macroeconomic Shocks and the Cross Section: Evidence from UK Quoted Companies [PDF]

open access: yes
Co-movements and correlations in the major macroeconomic aggregates has been the focus of much of the recent literature in business cycle research. In this paper we provide another dimension to business cycle analysis.

Harnessing the power of machine and deep learning for transferring joint species distribution models considering the structure of biotic interactions

open access: yesEcography, EarlyView.
The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially

Plant adaptive strategies respond to environmental change across European grassland habitats

open access: yesEcography, EarlyView.
Grassland ecosystems are facing rapid and ongoing change driven by intensified land‐use and accelerated climate change, highlighting the urgent need to understand their potential adaptation and response to environmental change. We analyzed data from 52 980 vegetation plots spanning all major grassland habitats in Europe (including alpine, rocky, sandy,

A duopoly Logit model with price competition and strategic compatibility [PDF]

open access: yes
This paper provides an analysis of compatibility decisions with oligopolistic price setting in a duopoly logit model. We consider a sequential game in which firms first choose whether they supply compatible products and then set the price which is ...

UPV MEDIA DIRECTORY

open access: yes, 2007
From the first second we heard about our project, we were very interested! We had to create a “media directory”. This means that people can upload their media files to a server. It’s possible to share the files with other users. We had to make this in the web language “PHP” in combination with “MySQL”. Before you can start scripting in PHP, a knowledge
