Residential solar photovoltaics deployment: barriers and drivers in space
In order to support a sustainability transition in the energy sector, actors need knowledge about barriers and drivers to the deployment of clean energy technologies. Solar photovoltaics (PV) is a renewable energy technology that is technically mature and on the verge of becoming economically competitive in numerous regions around the world. Not least in the residential segment, PV has considerabl
Mechanisms for Acceleration of Halide Anation Reactions of Platinum(IV) Complexes. REOA versus Ligand Assistance and Platinu(II) Catalysis without Central Ion Exchange
Chloride anation of trans-Pt(CN)4ClOH2− has been studied with and without Pt(CN)42− present at 25.0 °C by use of stopped-flow and conventional spectrophotometry and a 1.00 M perchlorate medium. The rate law in the absence of Pt(CN)42− is compatible with a chloride assistance via an intermediate of the type Cl-Cl-Pt(CN)4···OH22−, in which the reactivity of the aqua ligand is enhanced due to a partiChloride anation of trans-Pt(CN)4ClOH2− has been studied with and without Pt(CN)42− present at 25.0°C by use of stopped-flow and conventional spectrophotometry and a 1.00 M perchlorate medium.

Redefining the subcultural : The sub and the cultural
Arguing against the previous research’s presumption that the subculturalconstitutes a single set of meaning, this article addresses the simplequestion of what constitutes the subcultural? What does it mean when weaddress an object, practice, identity, or meaning structure as subcultural?Through outlining three dominant strands in regards to how subculturaldifference has been defined, the author ar
Scrolling down the line : A few notes on using Instagram as point of access for graffiti research
This article discusses using social media, here Instagram, as a point of access in studies on subcultural graffiti, so as to provide an established arena for initiating contact with a variety of participants. Drawing from an ongoing ethnography of Swedish graffiti writers, the approach presented here works to mitigate the often so major hurdle within ethnographic work on subcultural groups: that o

Private schools in the People's Republic of China: Development, modalities and contradictions
Chinese private schools may come across as a contradictory phenomenon: why would an authoritarian and officially socialist government, that needs to rely on education as an instrument of national unification and ideological control, allow for private schools and profit-making in the educational sector? However, seen against the background of the far-reaching privatisation processes that have been
From data to development : using qualitative data to create ideas and solutions
During autumn 2015 we conducted a large qualitative user study on our library as a learning space. The purpose of the study was to find evidence regarding user needs, in order to be able to make well-informed decisions for a development project.The paper will discuss both the usefulness of qualitative methods in understandingstudents’ and researchers’ needs and requirements when using the library,

Stabilities, Solubility and Kinetics and Mechanism for Formation and Hydrolysis of some Palladium(II) and Platinum(II) Iodo Complexes in Aqueous Solution
Complex formation between Pd(II), Pt(II) and iodide has been studied at 25 °C for an aqueous 1.00 M perchloric acid medium. Measurements of the solubility of PdI2(s) in aqueous mercury(II) perchlorate and of AgI(s) and PdI2(s) in aqueous solutions of Pd2+(aq) and Ag+(aq) gave the solubility product of PdI2(s) as Kso=(7±3) × 10−32 M3, which is much smaller than previous literature values.The stabilComplex formation between Pd(II), Pt(II) and iodide has been studied at 25 °C for an aqueous 1.00 M perchloric acid medium.

Modeling vegetation and ecosystem responses to climate change and fire regime
Climatic fire danger will likely increase because more droughts and heat-waves are caused by climate change. Climate change can shift fires from occurring only rarely to regularly in ecosystems not until now adapted to fire. We applied dynamic vegetation-fire models to investigate these future responses. The future of fire in Mediterranean-type ecosystems depends strongly on changes in vegetation
Threats of projected changes in fire regime for newly affected areas in Europe and Northern Africa
Under climate change conditions, climatic wildfire danger could also increase in ecosystems not dominated by fires until now. This increasing trend could lead to more area burned in the future. We have developed an algorithm to map new fire-prone areas in Europe and Northern Africa that identifies grid points where a rare fire event is becoming the mean at the end of the 21st century. When applyin
Land-atmosphere interactions and regional Earth system dynamics due to natural and anthropogenic vegetation changes
Observationer och modelleringsstudier har visat att den globala markytan har genomgått betydande förändringar under de senaste decennierna, drivet av både naturliga och antropogena faktorer, såsom förändringar i ekosystemens produktivitet, bränder och markanvändning. Markytans förändringar kan potentiellt påverka det lokala och regionala klimatet genom förändringar i processer som sker mellan jordObservation and modelling studies have indicated that the global land surfaces have been undergoing significant changes in the past few decades, driven by both natural and anthropogenic factors, such as changes in ecosystem productivity, fire and land use. Land surface changes can potentially influence local and regional climate through land-atmosphere interactions. Continued greenhouse gas emissi
Improving contact force estimation accuracy by optimal redundancy resolution
Estimating Cartesian contact forces and torques enables external force supervision for robotic manipulators and even force-controlled applications while avoiding the need for additional external sensing. Redundant manipulators facilitate the problem of Cartesian contact force and torque estimation (CCFE) at the TCP, since an increased amount of joint level information is available for estimating t
Packet routing and frame length optimization in wireless mesh networks with multicast communications
The paper considers multi-hop wireless mesh networks that serve multicast periodic packet traffic. The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at t
