Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm. [PDF]

Appl Plant Sci
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Aging and longevity in decades-old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays. [PDF]

Am J Bot
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

Microtubule-affinity regulating kinase family members distinctively affect tau phosphorylation and promote its toxicity in a Drosophila model. [PDF]

Genes Cells
Members of the Microtubule Affinity Regulating Kinase family (MARK1‐4) phosphorylate tau at microtubule‐binding repeats and are considered potential therapeutic targets for AD. We analyzed how each member of the MARK family affects tau phosphorylation and toxicity in a Drosophila model.

Dynamic behavior and flame acceleration of spherically expanding hydrogen flames under the low-pressure conditions

Nihon Kikai Gakkai ronbunshu, 2023
To investigate the dynamic behavior and flame acceleration of spherically expanding hydrogen flames under the low-pressure conditions, the deflagration experiments were conducted in a closed combustion chamber. The dynamic behavior of hydrogen flames was

Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames

Journal of Thermal Science and Technology, 2022
In this study, we have investigated turbulent premixed flames affected by local stretch in a swirl flow, measured by the simultaneous OH-PLIF/SPIV system. Evaluating the transient of burning velocity and stretch rate, the flow and the flame dynamics in a

CFD Analysis of Explosions with Hydrogen-Methane-Air Mixtures in Congested Geometries

Chemical Engineering Transactions, 2022
Hydrogen is an enabler for de-carbonising the energy system in Europe by 2050. In the UK, several projects are investigating the feasibility of gradually blending hydrogen into the natural gas pipelines with the aim to reach 100% hydrogen in the gas ...

In Situ (Operando) Electrochemical Dilatometry as a Method to Distinguish Charge Storage Mechanisms and Metal Plating Processes for Sodium and Lithium Ions in Hard Carbon Battery Electrodes

Advanced Materials Interfaces, Volume 9, Issue 8, March 11, 2022., 2022
Plating only for sodium: The storage mechanism of sodium and lithium ions in hard carbon is investigated by monitoring the change of the electrode thickness during charging and discharging. For lithium ions, a two‐step mechanism is found, whereas for sodium ions, a three‐step mechanism with a plating process as the last mechanism is found.

Laminar Flame Characteristics of Premixed Methanol–Water–Air Mixture

Energies, 2020
Methanol is hygroscopic in a gaseous state and is a promising alternative fuel for internal combustion engines. It is understood that adding water can improve the antiknock performance for spark ignition engines, but this will also affect the flame speed
