Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Micromachined needle-like calorimetric flow sensor for sap flux density measurement in the xylem of plants

open access: yesScientific Reports
Miniaturized silicon thermal probes for plant’s sap flow measurement, or micro sap flow sensors, have advantages in minimum invasiveness, low power consumption, and fast responses. Practical applications in sap flow measurement has been demonstrated with

Asymptotic and numerical analysis of a porous medium model for transpiration-driven sap flow in trees

open access: yes, 2017
We develop a 3D porous medium model for sap flow within a tree stem, which consists of a nonlinear parabolic partial differential equation with a suitable transpiration source term. Using an asymptotic analysis, we derive approximate series solutions for

Olive water use and crop coefficients from energy balance and radiometric canopy temperatures [PDF]

open access: yes, 2016
Biophysical and meteorological variables as well as radiometric canopy temperatures were collected in an intensive orchard near Évora, Portugal, with 28% ground cover by canopy and combined in a simplified two-source energy balance model (STSEB) to ...

Anifrolumab Treatment Leads to Rapid Reduction in Urinary Biomarkers of Intrarenal Inflammation in Lupus Nephritis: Results From the Phase 2 Randomized Trial

open access: yesArthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is one of the most severe manifestations of systemic lupus erythematosus (SLE) and is partially driven by type I interferon signaling. Anifrolumab, an approved treatment for patients with SLE, has been investigated in a phase 2 trial in patients with LN receiving standard therapy (TULIP‐LN, ClinicalTrials.gov identifier ...

Estimation of beech tree transpiration in relation to their social status in forest stand

open access: yesJournal of Forest Science, 2002
The results of sap flow continuous measurements by a tree-trunk heat balance method (THB) on beech model trees are analysed in this paper. Experimental research works were carried out in a mature mixed fir-spruce-beech stand in the research area Poľana -

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]

open access: yes, 2017
The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient
