Owing to its diagenetic instability, aragonite is rare in the geological record and almost entirely absent from pre-carboniferous sedimentary rocks. The former presence of this mineral in older deposits has to be inferred from petrographic, chemical or isotopic proxies. Crystals of aragonite that formed around 4563 million years ago occur in carbonaceous chondrite meteorites, showing that under ce
This paper examines information services in association with charging services, and in particular players that offer information services related to charging service offerings from many different operators. It identifies two main types of business models through studying and comparing 25 European charging information service providers. For one type of players the paper analyses the network charact
Solar cells based on metal-halide perovskite semiconductors inspire high hopes for efficient low cost solar cell technology. This material class exhibits a facile tunability of the band gap making them interesting for multi-junction device technology. We here compare and highlight trends in the band gap tunability and device performance metrics in reported metal halide perovskite alloys of a wide
A new simplifed formula is derived for the absorption cross section of small dielectric ellipsoidal particles embedded in lossy media. The new expression leads directly to a closed form solution for the optimal conjugate match with respect to the surrounding medium, i.e. the optimal permittivity of the ellipsoidal particle that maximizes the absorption at any given frequency. This defnes the optim
Foreign direct investment (FDI) has been important in the growth and global integration of developing economies. Both Northeast and Southeast Asia, especially the latter, have been part of this development, with increasing inflows of FDI and greater foreign participation in local economies. However, Indonesia has been an outlier within the region. Inflows of FDI have been lower to Indonesia than t
Hailed by economists as an idea whose time has come, the `new economic geography' has not been quite as favourably received by geographers. Frequently seen as a prime case of academic imperialism, few appear willing to concede that economists may have something to contribute to economic geography. Conversely, beyond the token reference to vintage publications, economistsoften dismiss geographers'
In the present study the inflammatory response was quantitatively evaluated during peripheral nerve regeneration. The fluid from silicone nerve regeneration chambers, inserted in rats, was collected during the early period of regeneration of transected sciatic nerves (6 h-7 d) and analysed with respect to inflammatory cells and mediators (leukotriene B4, LTB4, and interleukin-1 alpha, IL-1 alpha).
Situated in a broader anthropocentric and speciesist structure, carnism serves to perpetuate the objectification and exploitation of other animals. In this paper, carnistic thinking is examined in the context of how it is commonly applied to dogs, who are framed as lovable, yet subordinate to humans. Through critically discussing the social system of domestication, and by relating carnistic ideolo
A low-latency and area-efficient FFT/IFFT scheme is presented. The main idea is to utilize OFDM guard bands to reduce the operation counts and processing time, which results in 42% latency reduction compared to the reported pipelined schemes. To realize this idea, a modified pipelined architecture and an efficient data scheduling scheme are proposed. Furthermore, the proposed architecture is scala
The reassigned spectrogram can be used to improve the readability of a time-frequency representation of a non-stationary and multi-component signal. However for transient signals the reassignment needs to be adapted in order to achieve good localisation of the signal components. One approach is to scale the reassignment. This paper shows that by adapting the shape of the time window used with the
Although pharmacological treatments can help alleviate mood symptoms in youth with paediatric bipolar disorder (PBD), residual symptoms still commonly persist. In many cases, these symptoms seriously affect the social and psychological development of children and adolescents suffering from PBD. Complementary interventions, such as psychosocial and psychoeducational treatments, can help children an
This paper presents a method for modeling and control of a piezo-actuated high-dynamic compensation mechanism (HDCM) for usage together with an industrial robot during a machining operation, such as milling in aluminum. The spindle is attached to the compensation mechanism and the robot holds the workpiece. Due to the inherent resonant character of mechanical constructions of this type, and the no
Effective utilization of the spatial domain enhances the capacity of a mobile radio network. A common technique is to use sector antennas, where the sectors are formed by weighting the outputs from the antenna elements. This results in spatial domain selectivity, which significantly improves the signal-to-(noise and interference) ratio in the received signals. However, the operation of the sector
The purpose of this work is to develop and implement a simple and robust preservation technology that can enhance food and economic security and thereby improve the lives of people in developing countries. The technique under development is termed “solar assisted pervaporation (SAP)”. It is a sustainable technology whereby fruit juices or purées are concentrated using reusable pouches made of “bre
In this study, we systematically assess the spatial variability in carbon and nitrogen balance simulations related to the choice of global circulation models (GCMs), representative concentration pathways (RCPs), spatial resolutions, and the downscaling methods used as calculated with LPJ-GUESS. We employed a complete factorial design and performed 24 simulations for Europe with different climate i
