Abstract

Cities and other human settlements are major contributors to climate change and are highly vulnerable to its impacts. They are also uniquely positioned to reduce greenhouse gas emissions and lead adaptation efforts. These compound challenges and opportunities require a comprehensive perspective on the public policy of human settlements. Drawing on core literature that has driven debate around cities and climate over recent decades, we put forward a set of boundary objects that can be applied to connect the knowledge of epistemic communities and support an integrated urbanism. We then use these boundary objects to develop the Goals-Intervention-Stakeholder-Enablers (GISE) framework for a public policy of human settlements that is both place-specific and provides insights and tools useful for climate action in cities and other human settlements worldwide. Using examples from Berlin, we apply this framework to show that climate mitigation and adaptation, public health, and well-being goals are closely linked and mutually supportive when a comprehensive approach to urban public policy is applied.

Abstract

Background and aim: Nonalcoholic fatty liver (NAFL) is a major cause of liver disease worldwide leading also to a higher risk of cardiovascular events. We aimed to evaluate the impact of fatty liver and fibrosis on cardiovascular risk factors in a general population. Materials and methods: 604 subjects included in the communitybased ABCD (Alimentazione, Benessere Cardiovascolare e Diabete) study were recruited. Steatosis (CAP >288 dB/m) and fibrosis (>8.7 KPa by M and >7.2 KPa by XL probe) were assessed with FibroScan. Cardiovascular risk was evaluated by the Atherosclerotic Cardiovascular Disease (ASCVD) risk estimator and defined low if

Abstract

Extensive research has been directed at replacing hydrazine and its simple derivatives in liquid propellant fuel applications. While no specific replacement has been discovered, much has been learned about what types of compounds will make good fuels. One compound that has been investigated is 2-dimethylaminoethylazide (DMAZ). DMAZ is simple to prepare, and from a handling perspective is less toxic than hydrazine. Though DMAZ is hypergolic with IRFNA, there is a significant ignition delay. The explanation, based on ab-initio calculations is that the onset of ignition involves proton transfer from the acid to the amine nitrogen, and in the lowest energy conformer of DMAZ the azide group inhibits this proton transfer. This offers some insight into how one might design a fuel that overcomes these deficiencies. Either the electron distribution could be altered to allow for an enhanced interaction between the proton and the amine nitrogen, or the molecule could be altered to move the azide group away from the amine group. In either case, the chemistry would have to be done so that the advantages found with the DMAZ molecule (i.e. toxicity and energy) are not lost. While several molecules using either one approach or the other have been identified, this paper focuses on, a molecule that takes advantage of both approaches. The replacement of the tertiary amine nitrogen in DMAZ with 1,1-dimethyl hydrazine results in a molecule, 1,1-dimethyl-2-[2-azidoethyl]hydrazine (DMAEH) with a (calculated) lowest energy conformation in which the tertiary amine nitrogen is free to interact with the acidic proton at ignition. In addition to obvious steric improvements, a group with adjacent unshared electron pairs results in an enhancement of this group's nucleophilicity. Attempts at synthesizing DMAEH have ultimately failed.
