How can children and young people have a voice in urban treescapes?

People and Nature, EarlyView.
Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Attitudes Toward Prenatal Interventions in the Fanconi Anemia Community

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective In‐utero cell and gene therapies may offer prenatal treatment options for inherited diseases. Preclinical data suggests in‐utero (IU) hematopoietic stem cell transplantation (HSCT) could prevent Fanconi anemia (FA) related bone marrow failure without genotoxic conditioning or immune suppression.

Prenatal and Perinatal Outcomes in Fetuses With Macrocystic Congenital Pulmonary Airway Malformations: Thoracoamniotic Shunting Versus Expectant Management

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Describe prenatal imaging characteristics, perinatal and postnatal outcomes in fetuses with isolated macrocystic congenital pulmonary airway malformations (CPAM) undergoing thoracoamniotic shunting (TAS) and expectant management. Methods Retrospective cohort study of 123 fetuses with isolated macrocystic CPAM managed at the Ontario ...

Plant biostimulants and their potential role in achieving the United Nations sustainable development goals

PLANTS, PEOPLE, PLANET, EarlyView.
Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

Propellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Charge signature on ionization-excitation of He by fast projectiles

Fizika A : a journal of experimental and theoretical physics, 1995
Formuliran je analitički izraz za diferencijalni udarni presjek ionizacije–ekscitacije He u He+(np) stanja visokoenergijskim nabijenim česticama. Nađeno je da je omjer diferencijalnog udarnog presjeka negativnih i pozitivnih projektila jednakovaljane brzine veći od jedan ako je energija izbačenog elektrona manja od polovine energije osnovnog stanja ...

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Predicting the accuracy of unguided artillery projectiles [PDF]

, 2016
A method for predicting the accuracy of unguided artillery projectiles is presented in this thesis. The goal was to develop a standalone program that would estimate accuracy without the need for a large database of weapon trajectory data.

Development of NMP‐001, A Nitromethane‐Based Green Propellant

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.

2 keV He and Ne ion scattering on a Cu(110) surface:Experiment vs simulation

, 1994
Scattering experiments performed at 143° with a TOF-ISS system on a Cu(110) single crystal indicate the very different sampling depth of He ions as compared with Ne ions.
