description: Liquid−liquid emulsions are used in a variety of industry sectors, including personal care, home care, food, and nutrition. The development of compact and modular systems and devices for creating emulsions with desired droplet size distribution (DSD) is becoming increasingly important. In this work, we have shown use of vortex-based cavitation devices for producing emulsions at nominal flow rate of 1 LPM and 20 LPM. We present new experimental results providing quantitative information on influence of multiple passes through the vortex based hydrodynamic cavitation (HC) device, type of oil and device scale on the breakage process and resulting DSDs. Multiple pass experiments were performed for generating oil-in-water emulsions containing 5 and 15% of oil. Rapeseed oil (RO) and tetrachloroethylene (TCE) were used as oil phases with densities of 915 and 1620 kg/m3 , respectively. The effect of pressure drop across the HC device in the range of 50−250 kPa on DSD was examined. The HC device was shown to exhibit significant higher efficiency compared to alternative emulsion making devices (i.e., homogenizers, venturi, and orifice-based HC devices), and the Sauter mean drop size was found to reduce from 66 μm to less than 2 μm after about 50 passes in all the device scales. The DSD of the RO−water system showed a bimodal nature, whereas monomodal DSD was found for TCE−water system. Preliminary simulations using the computational fluid dynamics−population balance model (CFD-PBM) models developed in the previous work indicated the inadequacy of developed models to capture the influence of cavitation on DSDs. By carrying out Hinze scale analysis of bimodal DSD, we for the first time showed the existence of two different mechanisms (one based on conventional turbulent shear and the other based on collapsing cavities) of droplet breakage in HC devices. The order of magnitude of turbulence energy dissipation rates generated due to collapsing cavity estimated using Hinze scale analysis showed good agreement with the values reported from cavity dynamics models. The presented experimental results and analysis will be useful for researchers and engineers interested in developing computational models and compact devices for producing emulsions of the desired DSD.

description: We propose a simple experiment to determine whether vortices persist above the superconducting transition temperature Tc in the pseudogap phase of high temperature cuprate superconductors. This involves using a magnetic dot to stabilize a vortex in a thin cuprate film beneath the dot. We calculate the magnetic field profile as a function of distance from the dot if a vortex is present, and discuss possible measurements that could be done to detect this. Finally, we comment on the temperature range where a stable vortex should be observable.

description: We report on low temperature conductance measurements of gold nanogaps fabricated by controlled electromigration. Fluctuations of the conductance due to quantum interferences and depending both on bias voltage and magnetic field are observed. By analyzing the voltage and magnetoconductance correlation functions we determine the type of electron trajectories generating the observed quantum interferences and the effective characteristic time of phase coherence in our device.

description: In today's digital age, all of us depend on a number of large companies to mean well with us: to guard our data, or at least to not abuse it too much without asking. Even if we wanted, we cannot take things into our own hands and reclaim our digital autonomy because too much depends on too many system operators. To help small-time users and sysadmins to fight this dependence, Jan Götte and Björn Scheuermann from HIIG have developed Inertial Hardware Security Modules, or IHSMs. IHSM-equipped low-budget servers provide high security even outside of well-protected data centers and enable us to regain our digital autonomy.

description: The effects of a displacive structural phase transition on sliding friction are in principle accessible to nanoscale tools such as the Atomic Force Microscopy, yet they are still surprisingly unexplored. We present model simulations demonstrating and clarifying the mechanism and potential impact of these effects. A structural order parameter inside the material will yield a contribution to stick-slip friction that is nonmonotonic as temperature crosses the phase transition, peaking at the critical Tc where critical fluctuations are strongest, and the sliding-induced order parameter local flips from one value to another more numerous. Accordingly, the friction below Tc is larger when the order parameter orientation is such that flips are more effectively triggered by the slider. The observability of these effects and their use for friction control are discussed, for future application to sliding on the surface of and ferro- or antiferro-distortive materials.

description: We use very large cosmological Smoothed-Particle-Hydrodynamics simulations to study the properties of high redshift Lyman-alpha emitters (LAEs). We identify star-forming galaxies at z=3.1 in a cosmological volume of 100 h^-1Mpc on a side. We develop a phenomenological model of absorption, scattering and escape of Lyman-alpha photons on the assumption that the clumpiness of the inter-stellar medium in a galaxy is correlated with the larger scale substructure richness. The radiative transfer effect proposed by Neufeld (1991) allows a large fraction of Lyman-alpha photons to escape from a clumpy galaxy even if it contains a substantial amount of dust. Our model reproduces, for the first time, all of the following observed properties of LAEs at z=3.1: the angular correlation function, ultra-violet and Lyman-alpha luminosity functions, and the equivalent width distribution. A simple model that takes only dust absorption into account fails in matching the observational data, suggesting that the kind of effect we consider is needed. Our model also predicts a bimodal age distribution for LAEs. There are old, massive and dusty LAEs, similar to recently found high redshift LAEs. The large LAEs have escape fractions of Lyman-alpha photons of f_esc ~ 0.05-0.1.

Functional analyses of three SUPPRESSOR OF mkk1 mkk2 proteins in plant immunity
Creators: name: Liu, Yanan
Publisher: name: University of British Columbia
Year: 2020

description: Plant immunity relies on two groups of pathogen receptors, plasma membrane-localized pattern-recognition receptors (PRRs) and intracellular nucleotide binding-leucine rich repeat receptors (NLRs). Mitogen-activated protein kinase (MAPK) cascades, which generally consist of MAPK kinase kinase (MAPKKK), MAPK kinase (MAPKK) and MAPK, play critical roles in plant immunity. Disruption of the MEKK1-MKK1/MKK2-MPK4 cascade in Arabidopsis results in an autoimmune phenotype in the mekk1, mkk1 mkk2 and mpk4 mutants. A mkk1 mkk2 suppressor screen led to the identification of the NLR SUMM2 (SUPPRESSOR OF MKK1 MKK2 2), suggesting that the MEKK1-MKK1/MKK2-MPK4 cascade is guarded by SUMM2 and that disruption of this cascade can lead to the activation of SUMM2-mediated immunity. This thesis reports the identification and characterization of three additional SUMM proteins, SUMM3, SUMM5 and SUMM6. SUMM3 encodes CALMODULIN-BINDING RECEPTOR-LIKE CYTOPLASMIC KINASE 3 (CRCK3). crck3 mutants suppress the constitutively activated immune responses in mekk1, mkk1 mkk2 and mpk4 mutants. CRCK3 was found to be a substrate of MPK4 and it interacts with SUMM2 in planta, suggesting that SUMM2 utilizes CRCK3 as a “guardee” or “decoy” to monitor the integrity of the MEKK1-MKK1/MKK2-MPK4 cascade. SUMM5 encodes protein phosphatase 5 (PP5), a highly conserved atypical phosphatase with an N-terminal tetratricopeptide domain. SUMM2 was shown to interact with Heat Shock Protein 90 (Hsp90) and PP5 in planta. Accumulation of SUMM2 is reduced in the pp5 knockout mutant, suggesting that PP5 acts as a co-chaperone to regulate the accumulation of SUMM2. SUMM6 encodes the malectin-like domain containing kinase MEDOS1 (MDS1). Mutations in MDS1 and its close homolog MDS2 have additive effects on suppression of the mkk1 mkk2 mutant phenotypes, suggesting that MDS1 and MDS2 have overlapping roles in promoting SUMM2-mediated immunity. MDS1 and CRCK3 were found to associate in planta, indicating that MDS1/MDS2 might promote SUMM2-mediated immunity by targeting CRCK3. Overall, my thesis work provides new insights on how plants sense pathogens using receptor proteins and how they maintain appropriate levels of these receptor proteins to ensure adequate defense response.

description: UHV-deposited films of the mixed phase of tetramethoxypyrene and tetracyanoquinodimethane (TMP1-TCNQ1) on gold have been studied using ultraviolet photoelectron spectroscopy (UPS), X-ray-diffraction (XRD), infrared (IR) spectroscopy and scanning tunnelling spectroscopy (STS). The formation of an intermolecular charge-transfer (CT) compound is evident from the appearance of new reflexes in XRD (d1= 0.894 nm, d2= 0.677 nm). A softening of the CN stretching vibration (red-shift by 7 cm-1) of TCNQ is visible in the IR spectra, being indicative of a CT of the order of 0.3e from TMP to TCNQ in the complex. Characteristic shifts of the electronic level positions occur in UPS and STS that are in reasonable agreement with the prediction of from DFT calculations (Gaussian03 with hybrid functional B3LYP). STS reveals a HOMO-LUMO gap of the CT complex of about 1.25 eV being much smaller than the gaps (>3.0 eV) of the pure moieties. The electron-injection and hole-injection barriers are 0.3 eV and 0.5 eV, respectively. Systematic differences in the positions of the HOMOs determined by UPS and STS are discussed in terms of the different information content of the two methods.

description: Agriculture constitutes one of the first and foremost forms of conscious and organised human activity. Its importance for the society and for the economy stems from its main purpose, namely to meet one of the basic human needs – to satisfy hunger. The period of almost 70 years under consideration brought about exceptional change in the case of Polish agriculture. It consisted of a systematic decline in the potential of agriculture in the economy. The factor that is specific to agriculture - land, evolved relatively the least. Land allocated for agricultural purposes reduced for about one quarter. Much deeper changes have taken place in the other two factors, universal from the point of view of the sectoral application, namely work (human resources) and capital. In the post-war period, trade in agri-food products, albeit small, remained of great importance for the development of Polish agriculture and the entire economy. The nature of the links in this area has also undergone significant changes. Since Poland’s accession to the European Union, the balance in foreign trade in agri-food products has been positive and has been growing steadily. This means that foreign customers are becoming increasingly interested in agricultural and food products from Poland. The strategic directions of development for Polish agriculture are the production of bovine meat, poultry meat, eggs, milk and milk products, butter, sugar, fruits, vegetables, pulses, potatoes and cereals. Food consumption has also undergone dynamic changes. The main goal of the paper is to define the position of agriculture in the national economy at various stages of development, as well as changing external conditions, including political, social and economic, which affect this position.

description: In this paper we present the results of a high resolution (5") CARMA and SZA survey of the 3mm continuum emission from 11 of the brightest (at 1.1mm) starless cores in the Perseus molecular cloud. We detect 2 of the 11 cores, both of which are composed of single structures, and the median 3 sigma upper limit for the non-detections is 0.2 M_sun in a 5" beam. These results are consisent with, and as stringent as, the low detection rate of compact 3mm continuum emission in dense cores in Perseus reported by Olmi et al. (2005). From the non-detection of multiple components in any of the eleven cores we conclude that starless core mass functions derived from bolometer maps at resolutions from 10"-30" (e.g. with MAMBO, SCUBA or Bolocam) are unlikely to be significantly biased by the blending of lower mass cores with small separations. These observations provide additional evidence that the majority of starless cores in Perseus have inner density profiles shallower than r^-2.

description: The subject of this paper is the analysis of agricultural insurance in the Republic of Serbia, which includes the types of agricultural insurance that exist in Serbian insurance market, the subjects that could be insured, as well as the insurance companies that are active in agricultural insurance at national level. The main goal of paper is to define the basic terms in agricultural insurance and to show the products and procedures in agricultural insurance offered by the insurance companies. Additional goal is to show the level of development and coverage of agricultural insurance in Serbia, as well as to point out the importance of insurance for agricultural development. In paper are used descriptive and deduction method, as well as desk research and descriptive statistics methods. Based on the conducted research, it is concluded that the current state in agricultural insurance in Serbia is quite low, while the main factors influencing this situation are underdeveloped agriculture and the fact that agricultural insurance is not mandatory. Insurance is significantly more represented in the crop than in livestock production.
Age and metallicity gradients in early-type galaxies: A dwarf to giant sequence

description: We studied the stellar populations of 40 early-type galaxies using medium resolution long-slit spectroscopy along their major axes (and along the minor axis for two of them), from 10^7 Msol to 10^12 Msol (-9.2 > M_B > -22.4 mag). All the studied galaxies lie on the mass-metallicity and age-mass relations. The transition type dwarfs deviate from the latter relation having younger mean age, and the low-mass dwarf spheroidals have older ages, marking a discontinuity in the relation, possibly due to selection effects. In all mass regimes, the mean metallicity gradients are approximately -0.2 and the mean age gradients +0.1 dex per decade of radius. The individual gradients are widely spread: $ -0.1 < \nabla_{\rm Age} < 0.4 $ and $-0.54 < \nabla_{[{\rm Fe/H}]} < +0.2 $. We do not find evidence for a correlation between the metallicity gradient and luminosity, velocity dispersion, central age or age gradient. Likewise, we do not find a correlation between the age gradient and any other parameter in bright early-type galaxies. In faint early-types with $M_B \gtrsim -17$ mag, on the other hand, we find a correlation between the age gradient and luminosity: the age gradient becomes more positive for fainter galaxies. We conclude that various physical mechanisms can lead to similar gradients and that these gradients are robust against the environmental effects. In particular, the gradients observed in dwarfs galaxies certainly survived the transformation of the progenitors through tidal harassment or/and ram-pressure stripping. The diversity of metallicity gradients amongst dwarf elliptical galaxies may reflect a plurality of progenitors' morphologies. The dwarfs with steep metallicity gradients could have originated from blue compact dwarfs and those with flat profiles from dwarf irregulars and late type spirals. (Abridged)

description: We present a determination of the luminosity functions of massive young stellar objects (MYSOs) and compact (C)HII regions within the Milky Way Galaxy using the large, well-selected sample of these sources identified by the Red MSX Source (RMS) survey. The MYSO luminosity function decreases monotonically such that there are few with $L\gtrsim 10^{5}$Lsol, whilst the CHII regions are detected up to ~10$^{6}Lsol. The lifetimes of these phases are also calculated as a function of luminosity by comparison with the luminosity function for local main-sequence OB stars. These indicate that the MYSO phase has a duration ranging from 4x10$^{5}$ yrs for 10$^{4}$Lsol to ~7x10$^{4}$ yrs at 10$^{5}$Lsol, whilst the CHII region phase lasts of order 3x10$^{5}$ yrs or ~3-10% of the exciting star's main-sequence lifetime. MYSOs between 10$^{4} Lsol and ~10$^{5}$ Lsol are massive but do not display the radio continuum or near-IR \HI{} recombination line emission indicative of an HII region, consistent with being swollen due to high ongoing or recent accretion rates. Above ~10$^{5}$ Lsol the MYSO phase lifetime becomes comparable to the main-sequence Kelvin-Helmholtz timescale, at which point the central star can rapidly contract onto the main-sequence even if still accreting, and ionise a CHII region, thus explaining why few highly luminous MYSOs are observed.

Characterization of cranberry field decline syndrome in British Columbia
Creators: name: Someya, Takuhiro
Publisher: name: University of British Columbia
Year: 2019

description: A condition called Cranberry Field Decline (CFD) has affected several cranberry beds in British Columbia, resulting in patches of severely reduced canopy density. To prevent the further expansion of declining patches, early diagnosis of CFD is critical. The symptoms of CFD were characterized by evaluating soil chemistry (pH and redox potential), plant growth (root health, upright density, canopy depth, and yield), and carbohydrate dynamics (Starch, glucose, fructose, and sucrose) in relation with the three levels of CFD development (declining, transitional, and normal) in four affected beds. For the carbohydrate analysis, it was hypothesized that starch content in stems (S_Sta) was different among the CFD development. Additionally, the effectiveness of sanding in beds for rehabilitating stressed vines was evaluated by measuring the growth characteristics under three levels of sand depth (0, 1.3, and 2.5 cm). The characterization of CFD showed no clear relationship between pH or redox potential and CFD development. Shoot density and growth did not change significantly, while lower canopy depth and root health constantly declined in the early phase of CFD development. However, all growth parameters sharply declined after the transitional condition. Starch content in stems declined from normal to declining areas, supporting the hypothesis. Hexose (sum of glucose and fructose) in uprights (U_Hex) to S_Sta ratio increased with the increasing severity of CFD. The results suggest that the stress-induced alteration of carbohydrate allocation under carbon deficiency may explain the changes in canopy structure in CFD-affected areas. Sanding at 2.5 cm significantly increased total upright density compared to control but slightly decreased yield. However, such impact was only seen in a bed with poor root health and deep brown canopy, suggesting the effect of sanding is influenced by bed condition.

description: This work is devoted to the development of an automatic flight control system for aircraft. The research set the following goals: 1) Analysis of literary sources related to aircraft control systems and automatic control theory. 2) Study of the mathematical model of the aircraft. 3) Application of the control synthesis method for the aircraft flight trajectory stabilization system. As a result of the work, the projection method for solving the problem of optimal stabilization of program movements was applied to calculate the optimal limited controls of the aircraft flight path stabilization system. A numerical experiment is presented, as a result of which all angles of deviation from a given flight trajectory tend to zero.
Pinning of spiral fluxons by giant screw dislocations in YBa_2Cu_3O_7 single crystals: Josephson analog of the fishtail effect

description: By using a highly sensitive homemade AC magnetic susceptibility technique, the magnetic flux penetration has been measured in YBa_2Cu_3O_7 single crystals with giant screw dislocations (having the structure of the Archimedean spirals) exhibiting a=3 spiral turnings, the pitch b=18.7 microns and the step height c=1.2nm (the last parameter is responsible for creation of extended weak-link structure around the giant defects). The magnetic field applied parallel to the surface enters winding around the weak-link regions of the screw in the form of the so-called spiral Josephson fluxons characterized by the temperature dependent pitch b_f(T). For a given temperature, a stabilization of the fluxon structure occurs when b_f(T) matches b (meaning an optimal pinning by the screw dislocations) and manifests itself as a pronounced low-field peak in the dependence of the susceptibility on magnetic field (applied normally to the surface) in the form resembling the high-field (Abrikosov) fishtail effect.

Non-linear Group Actions with Polynomial Invariant Rings and a Structure Theorem for Modular Galois Extensions

description: Let $G$ be a finite $p$-group and $k$ a field of characteristic $p>0$. We show that $G$ has a \emph{non-linear} faithful action on a polynomial ring $U$ of dimension $n=\mathrm{log}_p(|G|)$ such that the invariant ring $U^G$ is also polynomial. This contrasts with the case of \emph{linear and graded} group actions with polynomial rings of invariants, where the classical theorem of Chevalley-Shephard-Todd and Serre requires $G$ to be generated by pseudo-reflections. Our result is part of a general theory of "trace surjective $G$-algebras", which, in the case of $p$-groups, coincide with the Galois ring-extensions in the sense of \cite{chr}. We consider the \emph{dehomogenized symmetric algebra} $D_k$, a polynomial ring with non-linear $G$-action, containing $U$ as a retract and we show that $D_k^G$ is a polynomial ring. Thus $U$ turns out to be \emph{universal} in the sense that every trace surjective $G$-algebra can be constructed from $U$ by "forming quotients and extending invariants". As a consequence we obtain a general structure theorem for Galois-extensions with given $p$-group as Galois group and any prescribed commutative $k$-algebra $R$ as invariant ring. This is a generalization of the Artin-Schreier-Witt theory of modular Galois field extensions of degree $p^s$.

Here I show that the amplitude of a state given by a superposition of sequences of events that share same total count (e.g., n detections of 0 and m of 1 in a spin 1/2 measurement) is proportional to the square root of the fraction - square root of the relative frequency - of all the equiprobable sequences of 0's and 1's with that n and m.

description: In this paper, the authors analyse the trend of agricultural production, at the agricultural holdings and enterprises active within the mentioned sector, in the period after the economic crisis in 2008., based on the submitted financial reports. The fact is that Serbia has favourable natural resources, but the achieved results are significantly below the average of EU member states. This indicates low labour productivity, as well as low competitiveness of legal entities involved in the agricultural sector. The analysis points out to the basic factors that influenced this state of the sector, but also to the possibilities of its dynamic and sustainable development. There is believe that participants in the production and trade of agricultural products can make a significantly greater contribution to overall economic growth, employment, exports and the creation of new value, but they need an adequate business environment and support of agricultural policy.

On the inversion of Stokes profiles with local stray-light contamination

description: Obtaining the magnetic properties of non-resolved structures in the solar photosphere is always challenging and problems arise because the inversion is carried out through the numerical minimization of a merit function that depends on the proposed model. We investigate the reliability of inversions in which the stray-light contamination is obtained from the same observations as a local average. In this case, we show that it is fundamental to include the covariance between the observed Stokes profiles and the stray-light contamination. The ensuing modified merit function of the inversion process penalizes large stray-light contaminations simply because of the presence of positive correlations between the observables and the stray-light, fundamentally produced by spatially variable systematics. We caution that using the wrong merit function, artificially large stray-light contaminations might be inferred. Since this effect disappears if the stray-light contamination is obtained as an average over the full field-of-view, we recommend to take into account stray-light contamination using a global approach.

description: Population growth and globalization are currently having many negative effects on the agri-food sector’s ability to ensure safe and qualitative food. Use of medicines and chemicals in animal husbandry can considerably increases production and animals’ resistance to disease and pests. Elevated levels of exposure to food contaminated with chemical residues from the use of antibiotics in animal husbandry and various growth hormones are very dangerous to human health. They contribute to genetic changes at the cellular level and decreased resistance of the body to viruses and bacteria. Frequent use of antibiotics may result in chemical residues in milk, meat, eggs and honey due to large-scale application of drugs in veterinary practice. In addition to its toxicity, antibiotic residues are carcinogenic and ingested in the long term lead to increased tolerance to medication against human diseases caused by deadly bacteria. Continuous monitoring of the production phase of the agri-food chain is absolutely necessary to identify the risks of contamination and reduce the use of illegal antibiotics in animal husbandry. This research aims to determine the main causes of food contamination with chemical residues and to create an overview of the negative effects that antibiotics have on human health.
Implementing virtual reality into the creative set design process

description: This thesis explores how the theatre industry could adopt virtual reality into the creative set design process to provide a director with a walkthrough of a set before it is built. The aim is to create a better visual platform for communication between a director and a scenic designer, as well as enhance collaboration with the entire production team. I investigate different software to achieve a successful workflow that is used in a case study that involves creating a set design from start to finish with a director and other industry professionals. The results and responses are evaluated to establish if virtual reality will benefit the creative set design process and how it can be used in other creative streams in the industry.

description: Dairy farming is the most significant part of cattle raising. During the previous several years the volume of milk production has been maintained at a stable level, while there came to fall in number of dairy cows and number of farms engaged in dairy farming. Although the farms that own just a few heads of dairy cows usually step out the milk production, there are still a small number of farms specialized in dairy farming. The main paper objective is to present the economic effects of investment in the construction and equipping of dairy farm adequate for raising of 12 dairy cows. Economic analysis was based on the use of static and dynamic methods for investment assessment. Besides, there is also conducted the analysis of investment under the risk conditions (use of the break-even analysis). According to gained results (e.g. Internal rate of return, 11.98%, positive value of the Net present value, Payback period shorter than 5 years) the investment implementation is economically justified.
