Horizontal movement of liquid containers is a common operation in an industrial packaging machine. During the movement the acceleration of the container induces motion of the liquid within the container, this is referred to as liquid slosh or liquid vibration. If there is too much slosh the liquid might wet the sealing surfaces of the container and even contaminate the machine. There is no measure
Crystal plasticity models are often used to model the deformation behavior of polycrystalline materials. One major drawback with such models is that they are computationally very demanding. Adopting the common Taylor assumption requires calculation of the response of several hundreds of individual grains to obtain the stress in a single integration point in the overlying FEM structure. However, a
We are living in a highly dynamic, human-dominated Earth System in which non-linear, abrupt and irreversible changes are not only possible but also probable. These changes require institutional structures capable of steering human society away from critical tipping points and irreversible change and ensuring sustainable livelihoods for all. We see 2012 as a charter moment, a historic opportunity t
Multimeric lactosides based on carbohydrate scaffolds with valencies ranging from 1 to 4 and different linker lengths were synthesized by a copper-catalyzed azide-alkyne cycloaddition (CuAAC). The binding affinities and crosslinking abilities of the new "click clusters" toward biologically relevant galectins (gal-1, gal-3) and peanut lectin were evaluated by fluorescent polarization assay (FPA) an

Our ever-changing world has to a great extent created a need of efficient financial risk-management programs for financial institutions and corporations operating in a demanding international environment. These changes have however also increased the types of financial tools and derivatives used to handle the multifold macroeconomic exposures. Companies have therefore diversified opportunities to
A major challenge in evolutionary biology is to understand how complex traits of multiple functions have diversified and codiversified across interacting lineages and geographic ranges. We evaluate intra- and interspecific variation in floral scent, which is a complex trait of documented importance for mutualistic and antagonistic interactions between plants, pollinators, and herbivores. We perfor
Purpose: To provide a focused review of sickle cell retinopathy in the light of recent advances in the pathogenesis, multimodal retinal imaging, management of the condition, and migration trends, which may lead to increased prevalence of the condition in the Western world. Methods: Non-systematic focused literature review. Results: Sickle retinopathy results from aggregation of abnormal hemoglobin
Among the irregular satellites orbiting Jupiter, the Himalia family is characterized by a high velocity dispersion dv of several hundred m s-1 among its members, inconsistent with a collisional origin. Efforts to account for this through internecine gravitational interactions do not readily reproduce this feature. Here, we revisit the problem in the context of recent cosmogonical models, where the
The Journal of Water Management and Research (Vatten) celebrates 2019 its 75th anniversary with a special issue, republishing one article per decade from 1940 to 2010. In the present article, we summarize the development of Swedish water research and management based upon the material published in the journal. We read all issues of the journal, noting important trends, percentage of female authors
Detection and classification of distresses is a fundamental activity in the road pavement management. Even in the early stages of deterioration, road pavement needs to be monitored to identify problems, evaluating the actual conditions and predicting what the future conditions will be. Monitoring activities through manual/visual inspections are time consuming, costly and cause of safety concerns.
The somatotype is a useful method in the analysis of body morphology but no study has identified genetic variants associated with its components. The aim of this study is o replicate the association of 21 SNPs with obesity and to explore their association with the somatotype components, in a sample from the Basque Country (Spain). A case-control study was performed in 472 adults from 18 to 79 year
Chromosomal rearrangements (e.g., fusions/fissions) have the potential to drive speciation. However, their accumulation in a population is generally viewed as unlikely, because chromosomal heterozygosity should lead to meiotic problems and aneuploid gametes. Canonical meiosis involves segregation of homologous chromosomes in meiosis I and sister chromatid segregation during meiosis II. In organism
We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda
Purpose - The dimple is adopted into a double wall cooling structure which is widely used in hot gas components to increase the heat transfer effects with relatively low pressure drop penalty. The purpose of this paper is to study the effect of dimple depth and dimple diameter on the target surface heat transfer and the inlet to outlet friction factor. Design/methodology/approach - The study is ca
