Dry powder inhalers are used by a large number of patients worldwide to treat respiratory diseases. The objective of this work is to experimentally investigate changes in aerosol particle diameter and particle number concentration of pharmaceutical aerosols generated by four dry powder inhalers under realistic inhalation and exhalation conditions. To simulate patients undergoing inhalation therapy, the active respiratory system model (xPULM™) was used. A mechanical upper airway model was developed, manufactured, and introduced as a part of the xPULM™ to represent the human upper respiratory tract with high fidelity. Integration of optical aerosol spectrometry technique into the setup allowed for evaluation of pharmaceutical aerosols. The results show that there is a significant difference (p < 0.05) in mean particle diameter between inhaled and exhaled particles with the majority of the particles depositing in the lung, while particles with the size of (>0.5 μm) are least influenced by deposition mechanisms. The fraction of exhaled particles ranges from 2.13% (HandiHaler®) over 2.94% (BreezHaler®), and 6.22% (Turbohaler®) to 10.24% (Ellipta®). These values are comparable to previously published studies. Furthermore, the mechanical upper airway model increases the resistance of the overall system and acts as a filter for larger particles (>3 μm). In conclusion, the xPULM™ active respiratory system model is a viable option for studying interactions of pharmaceutical aerosols and the respiratory tract regarding applicable deposition mechanisms. The model strives to support the reduction of animal experimentation in aerosol research and provides an alternative to experiments with human subjects.

Engineering education courses look into processes, equipment and people in order to prepare students to tackle problems in their careers. In manufacturing industry, it is important to use virtual manufacturing tools to analyse processes. This includes both equipment and people. Assembly operations can involve human operators. Modular arrangements of predetermined time standards MODAPTS is a predetermined motion time system method used to analyse assembly processes. Augmented reality (AR) is increasingly being used for industrial processes as well as in education. AR application have been used for maintenance training as a useful way to overly digital instructions to a trainee whilst being able to look at a real object. This is potential beneficial for education. This paper presents the evaluation of a prototype to test a predetermined time standards model using an AR application. An evaluation was carried out comparing AR-based instructions in tablet and PC monitor and paper-written instructions. The results of evaluating the prototype encourage their use as an educational tool in engineering courses.
Entrepreneurs keep the economy and society going by implementing new ideas. Entrepreneurship competencies such as creativity, risk tolerance or perseverance do not only emerge in professional life, but are already developed in early phases of socialization. Entrepreneurship education with its strongly action-oriented teaching and learning formats plays a triggering and process-reinforcing role in this respect. However, the competencies acquired through entrepreneurship education are also increasingly important for successful action in dependent employment. This article first shows that the goals and means of Entrepreneurship Education harmonize with the high practical relevance of teaching required by the Austrian Universities of Applied Sciences Act. Against this background, a concrete example of implementation is used to illustrate how the curricular anchoring of a student project in an engineering course can promote not only the practical relevance of teaching, but also the teaching of entrepreneurial competencies and the transfer of innovation between the university and industry.
In the present work, using the recently introduced framework of local geometric deformations, special types of vector fields – so-called hidden Killing vector fields – are constructed, which solve the Killing equation not globally, but only locally, i.e. in local subregions of spacetime. Taking advantage of the fact that the vector fields coincide locally with Killing fields and therefore allow the consideration of integral laws that convert into exact physical conservation laws on local scales, balance laws in dynamical systems without global Killing symmetries are derived that mimic as closely as possible the conservation laws for energy and angular momentum of highly symmetric models. The utility of said balance laws is demonstrated by a concrete geometric example, namely a toy model for the binary merger of two extremal Reissner–Nordström black holes.
In this paper, using the quasilocal formalism of Brown and York, the flow of energy through a closed surface containing a gravitating physical system is calculated in a way that augments earlier results on the subject by Booth and Creighton. To this end, by performing a variation of the total gravitational Hamiltonian (bulk plus boundary part), it is shown that associated tidal heating and deformation effects generally are larger than expected. This is because the aforementioned variation leads to previously unrecognized correction terms, including a bulk-to-boundary inflow term that does not appear in the original calculation of the time derivative of the Brown-York energy and leads to corrective extensions of Einstein’s quadrupole formula in the large sphere limit.
It has recently been shown that matter-wave interferometry can be used to imprint a periodic nanostructure onto a molecular beam, which provides a highly sensitive tool for beam displacement measurements. Herein, we used this feature to measure electronic properties of provitamin A, vitamin E, and vitamin K1 in the gas phase for the first time. The shift of the matter-wave fringes in a static electric field encodes the molecular susceptibility and the time-averaged dynamic electric dipole moment. The dependence of the fringe pattern on the intensity of the central light-wave diffraction grating was used to determine the molecular optical polarizability. Comparison of our experimental findings with molecular dynamics simulations and density functional theory provides a rich picture of the electronic structures and dynamics of these biomolecules in the gas phase with β-carotene as a particularly interesting example.
Designing experiments which delocalize ever more complex and more massive particles requires a quantitative assessment of new interferometer configurations. Here, we introduce a figure of
merit which quantifies the difference between a genuine quantum interference pattern and a classical shadow and use it to compare a number of near-field interferometer schemes. This allows us to identify the most promising setups for future tests of the quantum superposition principle, and to discuss the perspectives of interferometry with complex molecules and clusters.
Talipot starch, a non-conventional starch source with a high yield (76%) from the stem pith of talipot palm (Corypha umbraculifera L.) was subjected to three different thermal treatments (dry-heat, heat-moisture and autoclave treatments) prior to phosphorylation. Upon dual modification of starch with thermal treatments and phosphorylation, the phosphorous content and degree of crosslinking significantly increased (p ≤ 0.05) and was confirmed by the increased peak intensity of P=O and P–O–C stretching vibrations compared to phosphorylated talipot starch in the FT-IR spectrum. The highest degree of crosslinking (0.00418) was observed in the autoclave pretreated phosphorylated talipot starch sample. Thermal pretreatment remarkably changed the granule morphology by creating fissures and grooves. The amylose content and relative crystallinity of all phosphorylated talipot starches significantly decreased (p ≤ 0.05) due to crosslinking by the formation of phosphodiester bonds, reducing the swelling power of dual-modified starches. Among all modified starches, dry-heat pretreated phosphorylated starch gel showed an improved light transmittance value of 28.4%, indicating reduced retrogradation tendency. Pasting and rheological properties represented that the thermal pretreated phosphorylated starch formed stronger gels that improved thermal and shear resistance. Autoclave treatment before phosphorylation of talipot starch showed the highest resistant starch content of 48.08%.
This paper will present the concepts of the EURYDICE project funded by the Erasmus + program. Within this project the focus on renewable energies with the overall goal to enhance employability. The energy generation landscape in South Africa is undergoing a fundamental transition, as the vision of the energy strategy is
to contribute to an affordable energy for all. This vision will be supported by innovative labs and portals which will be developed within this project.
One of the goals is closing the gap between TVET (Technical and Vocational Education and Training Colleges) studies and diploma study by the definition of industrial experience requirements for University of Technology (UoT) diploma students. This leads to an increased preparedness and “studyability” of UoT diploma students. Industrial stakeholders will be integrated into the process. The project will develop an “Industrial Portal” as a working tool.
To increase industry cooperation in post graduate education “OpenLabs” and “MobileLabs” will be developed within the project. It is intended that industry brings industrial problems into the “Labs”, which will then be solved by the students.
In tropical fruits such as durian (Durio zibethinus) and jackfruit (Artocarpus
heterophyllus), only one quarter to one third of the fruit is edible. Finding more
ways to industrially use the other components of the fruit can reduce the waste
burned or dumped in landfills. Another fruit tree of interest that can also grow
in Austria is the fig tree (Ficus carica). Currently, the fruits are the main product
of that plant; however, components in the latex of the tree are of interest too.
The latex is known to contain natural rubber, which could potentially be used for
industrial applications. Jackfruit trees also produce latex, which contains natural
rubber. In both cases, the natural rubber has different properties compared to
the conventionally used rubber from the rubber tree (Hevea brasiliensis). This
could provide new opportunities in various applications. Therefore, the purpose
of this research is to analyze the properties of the natural rubber obtained from
the jackfruit and fig trees. Additionally, durian fruit also produces a sticky liquid,
so the same experiments were also carried out with durian samples.
The experimental procedure included extraction with acetone and
cyclohexane as well as polymer length determination with gel permeation
chromatography and polymer analysis with differential scanning calorimetry.
The results show that in both jackfruit and fig tree latex, there is natural
rubber of similar polymer length. Durian pulp also contains a polymer; however,
with these experiments, it could not be identified. Further research is required to
identify the durian polymer and to confirm the results of this experiment.
On the surface, the process landscape for fixed income securities trading within most banks has changed only slightly in the past four decades. The value chain remains divided amongst front-, middle-, and back office, with IT in support. Front office negotiates deals with customers and other banks, middle office manages risks and reporting, and back office ensures that payments are made in exchange for a transfer of the bonds that have been traded. Though these processes have gradually migrated to electronic mediums, much of the work in all functional areas remains manual. But the advent of digital technologies, primarily process automation software and data integration in an open software architecture, allows banks to dramatically change how the processes along the value chain are carried out. Repetitive and predictable tasks can be performed by automated software, allowing humans to concentrate on complex activities that require flexibility and discretion. Those tasks that remain in the hands of humans can also be made more efficient by extracting data from software applications along the entire process chain and providing them to the human user at the right point in time in the right system.
After a discussion about the possibilities and status of augmented reality in education, a good
practice example of an augmented reality application is presented. This case study examines the
use of an augmented reality app in higher education to support abstract STEM content, such as
vectors. Based on this example, the implementation of such apps in didactic concepts and self -
directed learning will be discussed. Furthermore, aspects of integration into digital learning and
teaching will be addressed.

A permutation can be locally classified according to the four local types: peaks, valleys, double rises and double falls. The corresponding classification of binary increasing trees uses four different types of nodes. Flajolet demonstrated the continued fraction representation of the generating function of local types, using a classical bijection between permutations, binary increasing trees, and suitably defined path diagrams induced by Motzkin paths.
The aim of this article is to extend the notion of local types from permutations to k-Stirling permutations (also known as k-multipermutations). We establish a bijection of these local types to node types of (k+1)-ary increasing trees. We present a branched continued fraction representation of the generating function of these local types through a bijection with path diagrams induced by Łukasiewicz paths, generalizing the results from permutations to arbitrary k-Stirling permutations.
We further show that the generating function of ordinary Stirling permutation has at least three branched continued fraction representations, using correspondences between non-standard increasing trees, k-Stirling permutations and path diagrams.
