In the present study, water-oil flow patterns and slug hydrodynamics were experimentally studied in square glass microchannels with various hydraulic diameters (Dh = 600 µm, 400 µm, 200 µm). The aqueous phase is the continuous phase while the organic phase is the dispersed phase. The ranges of flow rates of the continuous phase and the dispersed phase are 0-200 ml/h and 0-12 ml/h, 0-120 ml/h and 0
Controlled experiments on software variants enable e-commerce companies to increase sales by providing user-adapted functionality. Our goal is to understand how the context of experimentation influences tool support. We performed a case study at Apptus that develops algorithms for e-commerce. We investigated how the case company uses experiments through five semi-structured interviews. We identifi
Removal of cyprinid fish is a widely used biomanipulation tool to transform turbid shallow eutrophic lakes in north temperate regions into a clear water state. We here evaluate the removal of cyprinids from streams as a supplement to lake fishing. Since cyprinids often aggregate in high densities in lake inlet/outlet streams during winter migration, removal of fish in this space-confined habitat m
An ethnomethodological point of departure is that people rely on shared knowledge when mutually accomplishing everyday situations. Whereas most residents in a nursing home have a reasonable previous knowledge of events such as bingo or Christmas dinners, other activities such as pub evenings and spa activities are unfamiliar. Using ethnographic data from a Swedish nursing home with a
Mutually adaptive interaction involves the robot as a partner as opposed to a tool, and requires that the robot is susceptible to similar environmental cues and behavior patterns as humans are. Recognition, or the acknowledgement of the other as person, is fundamental to mutually adaptive interaction between humans. We discuss what embodied recognition involves and its behavioral manifestations, a
Today, cities become more dense, green spaces disappear and children spend less time outdoors. Research suggests that these conditions create health problems and lack of ecological literacy. To reverse such trends, localities are creating urban green spaces for children to visit during school time. Drawing on ideas in ecological literacy, this study investigates school children’s perspectives on a
In this paper we extend the color dipole formalism to the study of exclusive processes associated with a leading neutron in ep collisions at high energies. The exclusive ρ, φ and J/Ψ production, as well as the deeply virtual Compton scattering, are analyzed assuming a diffractive interaction between the color dipole and the pion emitted by the incident proton. We compare our predictions with the H
Purpose: To illuminate the experience of nurses providing health care to undocumented migrants in a voluntary network. Methods and sample: In a qualitative study, semistructured interviews were conducted with RNs regarding their experience of providing health care to undocumented migrants within a voluntary network. The interview transcripts were analysed using the inductive method of content anal
Background: Presence of circulating tumor cells (CTCs) is a validated prognostic marker in metastatic breast cancer. Additional prognostic information may be obtained by morphologic characterization of CTCs. We explored whether apoptotic CTCs, CTC clusters and leukocytes attached to CTCs are associated with breast cancer subtype and prognosis at base-line (BL) and in follow-up (FU) blood samples i
A novel feature set for low-dimensional signal representation, designed for classification or clustering of non-stationary signals with complex variation in time and frequency, is presented. The feature representation of a signal is given by the first left and right singular vectors of its ambiguity spectrum matrix. If the ambiguity matrix is of low rank, most signal information in time direction
A field study on current structure and circulation characteristics in Lake Vendyurskoe, a small, shallow, icecovered lake in Karelia, Russia, is presented. The current velocity magnitudes were generally found to be small. The most pronounced currents had an oscillating character, with velocity amplitudes on the order of millimeters per second. The oscillation period, obtained from spectral density
Our study aims to investigate the relationships of the major lineages within the moth family Geometridae, with a focus on the poorly studied Oenochrominae- Desmobathrinae complex, and to translate some of the results into a coherent subfamilial and tribal level classification for the family. We analyzed a molecular dataset of 1,206 Geometroidea terminal taxa from all biogeographical regions compri
Objectives: NEAT001/ANRS143 demonstrated non-inferiority of once-daily darunavir/ritonavir (800/100 mg) + twice-daily raltegravir (400 mg) versus darunavir/ritonavir + tenofovir disoproxil fumarate/emtricitabine (245/200 mg once daily) in treatment-naive patients. We investigated the population pharmacokinetics of darunavir, ritonavir, tenofovir and emtricitabine and relationships with demographic
Background: Sweden is a long-standing and significant contributor to overseas development aid. This commitment to global health and development is part of Sverigebilden, or the view of Sweden in the world that is formally promoted by the Swedish government. Sweden is seen by many in the global health community as leader on human rights and health and has traditionally been one of the most engaged
A 6-year-old girl with a neurogenic bladder disease is described. Additional gait disturbances and mild but progressive foot deformities led to the diagnosis and surgical treatment of a ganglioneuroma located exclusively intraspinally. It is suggested that the tumor originated from remnant neural crest cells, probably early in life or even prenatally.
Hybrid nanowires combining semiconductor and superconductor materials appear well suited for the creation, detection, and control of Majorana bound states (MBSs). We demonstrate the emergence of MBSs from coalescing Andreev bound states (ABSs) in a hybrid InAs nanowire with epitaxial Al, using a quantum dot at the end of the nanowire as a spectrometer. Electrostatic gating tuned the nanowire densi
Single-incision laparoscopic appendectomy (SILA) has gained popularity in children, and several different techniques have been described, including intracorporeal and extracorporeal techniques and single-channel and multi-channel single-port techniques. However, there has been a concern that exteriorizing an infected appendix through the umbilical channel would increase the risk of postoperative w
