Two-dimensional computational fluid dynamics analysis of internal flow in a simplified solid rocket motor combustion chamber

open access: yesJournal of Fluid Science and Technology, 2017
Many countries in recent year have focused on small satellite launch. Therefore, Solid Rocket Motor (SRM) plays an important role in the development of small satellites.

Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...

The strategic and governance implications of solar radiation modification: perspectives from delegates of international climate negotiations

open access: yesEnvironmental Research Letters
The lack of progress in addressing climate change has led to increased interest in solar radiation modification (SRM)—a collection of large-scale interventions that cool the planet by managing the amount of solar radiation that reaches the earth.

The security implications of geoengineering:blame,imposed agreement and the security of critical infrastructure [PDF]

open access: yes, 2014
The prospect of solar geoengineering in response to climate change (on the basis of its supposedly significantly lower cost and/or more rapid impact on global temperature than carbon reduction strategies) raises a number of security concerns that have ...

Baryon number conservation in Bose-Einstein condensate black holes

open access: yes, 2015
Primordial black holes are studied in the Bose-Einstein condensate description of space-time. The question of baryon-number conservation is investigated with emphasis on possible formation of bound states of the system's remaining captured baryons.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Analysis of Switched Reluctance Motor Behavior under Electrical Fault Conditions

open access: yesCommunications, 2013
This paper deals with analysis of Switched Reluctance Motor (SRM) behavior under fault conditions. The static parameters of the healthy SRM and SRM with defined faults of phases are investigated by Finite Element Method (FEM). These static parameters are

Risk Factors for Relapse in Antineutrophil Cytoplasmic Antibody–Associated Vasculitis Among Patients With Relapse After Induction of Remission With Rituximab

open access: yesArthritis &Rheumatology, EarlyView.
Objective The objective of the study was to determine risk factors for relapse of antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) after reinduction of remission with rituximab and discontinuation of maintenance therapy. Methods This is a post hoc analysis of the RITAZAREM clinical trial.
