description: Hyperalonia chilensis Rondani, 1863
ORIGINAL DESCRIPTION: 1863: 58 (key), 59 (description).
TYPE LOCALITY: “ Chiliae [Chile]”.
TYPE MATERIAL: 1 ♀, holotype (MZUN: Box Antracidei A 03,01): Hyperalonia chilensis Rnd., Chili [= Chile] / M. Zool. N° 11118.
CURRENT STATUS: valid species (Evenhuis & Greathead 1999: 400, 2015: 414).
REMARKS: Rondani (1863: 59) described Hyperalonia chilensis, without specifying the number, the sex or the length of the specimens, from material received from R.A. Philippi. Costa (1866: 37) listed a single MZUN specimen numbered “824”. Evenhuis & Greathead (1999: 400) reported the specimen in the MZUN to be a holotype. O’Hara et al. (2011: 208) incorrectly considered this nominal species under the generic name Exoprosopa Macquart, 1840.

description: We calculate the closed analytic form of the solution of heat kernel equation for the anisotropic generalizations of flat Laplacian. We consider a UV as well as UV/IR interpolating generalizations. In all cases, the result can be expressed in terms of Fox-Wright psi-functions. We perform different consistency checks, analytically reproducing some of the previous numerical or qualitative results, such as spectral dimension flow. Our study should be considered as a first step towards the construction of a heat kernel for curved Hořava-Lifshitz geometries, which is an essential ingredient in the spectral action approach to the construction of the Hořava-Lifshitz gravity.

description: We present our fifth set of results from our mid-infrared imaging survey of Milky Way Giant HII (GHII) regions with our detailed analysis of DR7 and K3-50. We obtained 20/25 and 37um imaging maps of both regions using the FORCAST instrument on the Stratospheric Observatory For Infrared Astronomy (SOFIA). We investigate the multi-scale properties of DR7 and K3-50 using our data in conjunction with previous multi-wavelength observations. Near to far-infrared spectral energy distributions of individual compact infrared sources were constructed and fitted with massive young stellar object (MYSO) models. We find eight out of the ten (80%) compact sources in K3-50 and three out of the four (75%) sources in DR7 are likely to be MYSOs. We derived luminosity-to-mass ratios of the extended radio sub-regions of DR7 and K3-50 to estimate their relative ages. The large spread in evolutionary state for the sub-regions in K3-50 likely indicates that the star-forming complex has undergone multiple star-forming events separated more widely in time, whereas the smaller spread in DR7 likely indicates the star formation sub-regions are more co-eval. DR7 and K3-50 have Lyman continuum photon rates just above the formal threshold criterion for being categorized as a GHII region (10^50 photons/s) but with large enough errors that this classification is uncertain. By measuring other observational characteristics in the infrared, we find that K3-50 has properties more akin to previous bona fide GHII regions we have studied, whereas DR7 has values more like those of the non-GHII regions we have previously studied.

description: We study quasiparticle dynamics in graphene exposed to a linearly-polarized electromagnetic wave of very large intensity. Low-energy transport in such system can be described by an effective time-independent Hamiltonian, characterized by multiple Dirac points in the first Brillouin zone. Around each Dirac point the spectrum is anisotropic: the velocity along the polarization of the radiation significantly exceeds the velocity in the perpendicular direction. Moreover, in some of the points the transverse velocity oscillates as a function of the radiation intensity. We find that the conductance of a graphene p-n junction in the regime of strong irradiation depends on the polarization as $G(θ)\propto|\sinθ|^{3/2}$, where $θ$ is the angle between the polarization and the p-n interface, and oscillates as a function of the radiation intensity.

description: We present a detailed procedure for treating data cubes obtained with the Near-Infrared Integral Field Spectrograph (NIFS) of the Gemini North telescope. This process includes the following steps: correction of the differential atmospheric refraction, spatial re-sampling, Butterworth spatial filtering, 'instrumental fingerprint' removal and Richardson-Lucy deconvolution. The clearer contours of the structures obtained with the spatial re-sampling, the high spatial-frequency noise removed with the Butterworth spatial filtering, the removed 'instrumental fingerprints' (which take the form of vertical stripes along the images) and the improvement of the spatial resolution obtained with the Richardson-Lucy deconvolution result in images with a considerably higher quality. An image of the Brγ emission line from the treated data cube of NGC 4151 allows the detection of individual ionized-gas clouds (almost undetectable without the treatment procedure) of the narrow-line region of this galaxy, which are also seen in an [O III] image obtained with the Hubble Space Telescope. The radial velocities determined for each one of these clouds seem to be compatible with models of biconical outflows proposed by previous studies. Considering the observed improvements, we believe that the procedure we describe in this work may result in more reliable analysis of data obtained with this instrument.

Good Regulation and Convergence in the Nigerian Telecommunications Sector

Subjects: Uncategorized

description: Nigeria’s telecommunications sector has emerged as a vital, regulated, investor friendly sector, accounting for 10.11% of Nigeria’s GDP in 2019. Despite the growing importance of the telecommunications sector, there has been little attempt to evaluate the regulatory framework, perhaps, due to the absence of a governmental statement on regulatory quality which could provide a foundation for measuring and improving regulation. This thesis offers an original contribution to knowledge by analysing to what extent good regulation exists under the current regulatory framework. It subjects the regulatory framework to scrutiny, employing Baldwin, Cave and Lodge’s criteria for good regulation in examining the existing legislative provisions and their practical implications. This thesis also analyses case law, which has received little analysis to date. Given the shortcomings identified in the areas of legislative mandate, accountability and due process, this thesis concludes that the regulatory framework requires extensive reform before it can be considered good regulation. Due to the dynamic nature of telecommunications, assessing the regulatory framework against a static picture is insufficient; it is essential to consider how future developments will affect good regulation. The boundaries of the telecommunications industry have begun shifting due to convergence which is the ability of one or several networks to carry different services and the bringing together of previously separate and distinct industries in the communications area. Convergence poses a challenge as the traditional regulatory frameworks were intended for an age when there was a clear distinction between various services. Convergence, therefore, dictates altering the current regulatory structure and introducing a converged regulator. This thesis argues that a converged regulator may impact on achieving good regulation by altering the appropriate legislative mandate, mounting accountability concerns, increasing the risk of regulatory capture, varying expertise requirements and encouraging productive efficiency. It also presents an opportunity to resolve pre-existing regulatory shortcomings.

description: We study the thermal Markovian diffusion of tracer particles in a 2D medium with spatially-varying diffusivity $D(r)$, mimicking recently measured, heterogeneous maps of the apparent diffusion coefficient in biological cells. For this heterogeneous diffusion process (HDP) we analyse the mean squared displacement (MSD) of the tracer particles, the time averaged MSD, the spatial probability density function, and the first passage time dynamics from the cell boundary to the nucleus. Moreover we examine the non-ergodic properties of this process which are important for the correct physical interpretation of time averages of observables obtained from single particle tracking experiments. From extensive computer simulations of the 2D stochastic Langevin equation we present an in-depth study of this HDP. In particular, we find that the MSDs along the radial and azimuthal directions in a circular domain obey anomalous and Brownian scaling, respectively. We demonstrate that the time averaged MSD stays linear as a function of the lag time and the system thus reveals a weak ergodicity breaking. Our results will enable one to rationalise the diffusive motion of larger tracer particles such as viruses or submicron beads in biological cells.

description: Aims. We estimate the dynamical evolution of the Globular Clusters interaction with the Galactic centre that dynamically changed in the past. Methods. We simulated the orbits of 147 globular clusters over 10 Gyr lookback time using the parallel N-body code phi-GPU. For each globular cluster, we generated 1000 sets of initial data with random proper motions and radial velocities based on the observed values. To distinguish globular clusters interacting with the galactic centre, we used the criterion of a relative distance of less than 100 pc. We used four external potentials from the IllustrisTNG-100 database, which were selected for their similarity to the present-day Milky Way, to simulate the structure of the Galaxy at different times. Results. We obtained 3-4 globular cluster interactions per Gyr at distances of less than 50 pc and 5-6 interactions per Gyr at distances of less than 80 pc among the studied 147 globular clusters that had close passages near the Galactic centre. We selected 10 of them for detailed study and found almost 100% probability of interaction with the Galactic centre for six of them. Conclusions. According to our results, the maximum interaction frequency of globular clusters with the Galactic centre in the Milky Way is likely to be a few dozens of passages per Gyr within a central zone of 100 pc. This low frequency may not be sufficient to fully explain the relatively high mass (of order 10^7 Msol) of the nuclear star cluster in the Milky Way, if we consider only the periodic capture of stars from globular clusters during close encounters. Therefore, we must also consider the possibility that some early globular clusters were completely tidally disrupted during interactions with the forming nuclear star cluster and the Galactic centre.

description: We have investigated via two-dimensional relativistic MHD simulations the long-term evolution of turbulence created by a relativistic shock propagating through an inhomogeneous medium. In the postshock region, magnetic field is strongly amplified by turbulent motions triggered by preshock density inhomogeneities. Using a long-simulation box we have followed the magnetic-field amplification until it is fully developed and saturated. The turbulent velocity is sub-relativistic even for a strong shock. Magnetic-field amplification is controled by the turbulent motion and saturation occurs when the magnetic energy is comparable to the turbulent kinetic energy. Magnetic-field amplification and saturation depend on the initial strength and direction of the magnetic field in the preshock medium, and on the shock strength. If the initial magnetic field is perpendicular to the shock normal, the magnetic field is first compressed at the shock and then can be amplified by turbulent motion in the postshock region. Saturation occurs when the magnetic energy becomes comparable to the turbulent kinetic energy in the postshock region. If the initial magnetic field in the preshock medium is strong, the postshock region becomes turbulent but significant field amplification does not occur. If the magnetic energy after shock compression is larger than the turbulent kinetic energy in the postshock region, significant field amplification does not occur. We discuss possible applications of our results to gamma-ray bursts and active galactic nuclei.

description: Correlations in Bell and noncontextuality inequalities can be expressed as a positive linear combination of probabilities of events. Exclusive events can be represented as adjacent vertices of a graph, so correlations can be associated to a subgraph. We show that the maximum value of the correlations for classical, quantum, and more general theories is the independence number, the Lovász number, and the fractional packing number of this subgraph, respectively. We also show that, for any graph, there is always a correlation experiment such that the set of quantum probabilities is exactly the Grötschel-Lovász-Schrijver theta body. This identifies these combinatorial notions as fundamental physical objects and provides a method for singling out experiments with quantum correlations on demand.

description: It is generally accepted that the main cause of ultracold neutron (UCN) losses in storage traps is the upscattering to the thermal energy range by hydrogen adsorbed on the surface of the trap walls. However, the data on which this conclusion is based are poor and contradictory. Here, we report a measurement, performed at the Los Alamos National Laboratory UCN source, of the average energy of the flux of upscattered neutrons after the interaction of UCN with hydrogen bound in semicrystalline polymer PMP (tradename TPX), [C$_{6}$H$_{12}$]$_n$. Our analysis, performed with the MCNP code based on the application of the neutron scattering law to UCN upscattered by bound hydrogen in semicrystalline polyethylene, [C$_{2}$H$_{4}$]$_n$, leads us to a flux average energy value of 26$\pm3$ meV in contradiction with previously reported experimental values of 10 to 13 meV and in agreement with the theoretical models of neutron heating implemented in the MCNP code.

description: Packings of hard polyhedra have been studied for centuries due to their mathematical aesthetic and more recently for their applications in fields such as nanoscience, granular and colloidal matter, and biology. In all these fields, particle shape is important for structure and properties, especially upon crowding. Here, we explore packing as a function of shape. By combining simulations and analytic calculations, we study three 2-parameter families of hard polyhedra and report an extensive and systematic analysis of the densest packings of more than 55,000 convex shapes. The three families have the symmetries of triangle groups (icosahedral, octahedral, tetrahedral) and interpolate between various symmetric solids (Platonic, Archimedean, Catalan). We find that optimal (maximum) packing density surfaces that reveal unexpected richness and complexity, containing as many as 130 different structures within a single family. Our results demonstrate the utility of thinking of shape not as a static property of an object in the context of packings, but rather as but one point in a higher dimensional shape space whose neighbors in that space may have identical or markedly different packings. Finally, we present and interpret our packing results in a consistent and generally applicable way by proposing a method to distinguish regions of packings and classify types of transitions between them.

description: We present a symmetry classification of the linearised Navier-Stokes equations for a two-dimensional unbounded linear shear flow of an incompressible fluid. The full set of symmetries is employed to systematically derive invariant ansatz functions. The symmetry analysis grasps three approaches. Two of them are existing ones, representing the classical normal modes and the Kelvin modes, while the third is a novel approach and leads to a new closed-form solution of traveling modes, showing qualitatively different behaviour in energetics, shape and kinematics when compared to the classical approaches. The last modes are energy conserving in the inviscid case. They are localized in the cross-stream direction and periodic in the streamwise direction. As for the kinematics, they travel at constant velocity in the cross-stream direction, whilst in the streamwise direction they are accelerated by the base flow. In the viscous case, the modes break down due to damping of high wavenumber contributions.

Angular momentum of circularly polarized light in dielectric media

description: A circularly polarized plane-wave is known to have no angular momentum when examined through Maxwell's equations. This, however, contradicts the experimentally observed facts, where finite segments of plane waves are known to be capable of imparting angular momentum to birefringent platelets. Using a superposition of four plane-waves propagating at slightly different angles to a common direction, we derive an expression for the angular momentum density of a single plane-wave in the limit when the propagation directions of the four beams come into alignment. We proceed to use this four-beam technique to analyze the conservation of angular momentum when a plane-wave enters a dielectric slab from the free space. The angular momentum of the beam is shown to decrease upon entering the dielectric medium, by virtue of the fact that the incident beam exerts a torque on the slab surface at the point of entry. When the beam leaves the slab, it imparts an equal but opposite torque to the exit facet, thus recovering its initial angular momentum upon re-emerging into the free-space. Along the way, we derive an expression for the outward-directed force of a normally incident, finite-diameter beam on a dielectric surface; the possible relationship between this force and the experimentally observed bulging of a liquid surface under intense illumination is explored.

description: This thesis is divided into two sections, encompassing two main topics: display calculi and nominal string diagrams. In the first section of the thesis, we introduce display calculi and present their advantages and drawbacks compared to sequent calculi. The rest of the section presents the calculus toolbox, a meta-tool for formalising display calculi. The tool includes a tree editor and a type-checker, which aid the user in exploring display calculi more efficiently. Section two grew out of an attempt to build a calculus of simultaneous substitutions for a display version of first order logic. This section explores the topic of string diagrams, in particular, we present two categorical formalisations of nominal string diagrams, along with a formal translation of ordinary string diagrams into nominal string diagrams (and vice versa).

description: In wind-fed X-ray binaries, the radiatively driven wind of the primary star can be suppressed by the EUV irradiation of the compact secondary star, leading to an increased accretion rate. This causes feedback between the released accretion power and the luminosity of the compact star. We investigate the feedback process between the released accretion power and the X-ray luminosity of the compact star in the unique high-mass X-ray binary Cygnus X-3. We assume that a part of the wind-fed power experiences a small amplitude variability around the source luminosity. We propose a simple heuristic model to couple the influence of EUV irradiation on the stellar wind (from the Wolf-Rayet companion star) with the X-ray source itself. The resulting time profile of luminosity mimics that of the input variability, albeit with a larger amplitude. The most important property of the input variability are turnover times when it changes its sign and starts to have either positive or negative feedback. The bolometric luminosity derived by spectral modeling is the time average of the resulting feedback luminosity. We demonstrate that the erratic behavior of the X-ray light curve of Cygnus X-3 may have its origin in the small amplitude variability of the X-ray source and feedback with the companion wind. This variability could arise in the accretion flow and/or due to the loss of kinetic energy in a jet or an accretion disk wind. In order to produce similar properties of the simulated light curve as observed, we have to restrict the largest accretion radius to a changing level, and assume variable timescales for the rise and decline phases of the light curve.

description: The presence of transitional dwarf galaxies in filaments and cluster outskirts may be closely related to pre-processing in the filament; however, the underlying mechanism is not yet comprehensively understood. We present the spatially resolved chemical and kinematical properties of three blue-cored dwarf early-type galaxies (dE(bc)s) in the Virgo cluster and Virgo-related filaments (Crater & Virgo III) using the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) Galaxy Survey. We map the spatial distribution of H-alpha, oxygen abundance (O/H), nitrogen-to-oxygen abundance ratio (N/O), stellar population age, and gas-stellar internal kinematics. We find irregular shapes of enhanced star-forming regions from the centers to the outlying regions of blue cores in dE(bc)s. These regions are relatively metal-poor compared with the surrounding regions, rendering the overall metallicity gradient of each galaxy positive. Furthermore, they exhibit higher N/O ratios at a given O/H relative to their surroundings, implying metal-poor gas infall by external processes. The equivalent width of the H-alpha emission line in metal-poor regions indicates young age of star formation, 6-8 Myr. The disturbed ionized gas velocity field, one of the most prominent features of galaxy mergers is also discovered in two dE(bc)s. We propose that a moderately dense filament environment is favorable for the formation of blue cores in dEs, in which dE(bc)s in filaments may have already been transformed before they fall into the Virgo cluster. This process may contribute to the composition of galaxy population at the outskirts of the cluster.

description: Classical novae are caused by mass transfer episodes from a main sequence star onto a white dwarf via Roche lobe overflow. This material forms an accretion disk around the white dwarf. Ultimately, a fraction of this material spirals in and piles up on the white dwarf surface under electron-degenerate conditions. The subsequently occurring thermonuclear runaway reaches hundreds of megakelvin and explosively ejects matter into the interstellar medium. The exact peak temperature strongly depends on the underlying white dwarf mass, the accreted mass and metallicity, and the initial white dwarf luminosity. Observations of elemental abundance enrichments in these classical nova events imply that the ejected matter consists not only of processed solar material from the main sequence partner but also of material from the outer layers of the underlying white dwarf. This indicates that white dwarf and accreted matter mix prior to the thermonuclear runaway. The processes by which this mixing occurs require further investigation to be understood. In this work, we analyze elemental abundances ejected from hydrodynamic nova models in search of elemental abundance ratios that are useful indicators of the total amount of mixing. We identify the abundance ratios $Σ$CNO/H, Ne/H, Mg/H, Al/H, and Si/H as useful mixing meters in ONe novae. The impact of thermonuclear reaction rate uncertainties on the mixing meters is investigated using Monte Carlo post-processing network calculations with temperature-density evolutions of all mass zones computed by the hydrodynamic models. We find that the current uncertainties in the $^{30}$P($p$,$γ$)$^{31}$S rate influence the Si/H abundance ratio, but overall the mixing meters found here are robust against nuclear physics uncertainties. A comparison of our results with observations of ONe novae provides strong constraints for classical nova models.

description: Hyperalonia surinamensis Rondani, 1863
ORIGINAL DESCRIPTION: 1863: 58.
TYPE LOCALITY: “ Surinam [Suriname]”.
TYPE MATERIAL: 1 ♀, holotype (MZUN: Box Antracidei A 03,01): Hyperalonia surinamensis Rnd., Surinam / M. Zool. N° 43078.
CURRENT STATUS: valid species (Evenhuis & Greathead 1999: 400, 2015: 415).
REMARKS: Rondani (1863: 58) described Hyperalonia surinamensis, without specifying the number, the sex or the length of the specimens, from material received from J.M.F. Bigot. Costa (1866: 37) listed a single MZUN specimen numbered “827”. O’Hara et al. (2011: 214) ascribed this nominal species to the genus Exoprosopa Macquart, 1840 in error. Evenhuis & Greathead (1999: 400) reported the specimen in the MZUN to be a holotype.

description: In this work, we systematically investigate the charmed-strange dibaryon systems with $csssqq$ quarks and their baryon-antibaryon partners from the interactions $Ξ^{(',*)}_{c}Ξ^{(*)}$, $Ω^{(*)}_cΛ$, $Ω^{(*)}_cΣ^{(*)}$, $Λ_cΩ$ and $Σ^{(*)}_cΩ$ and their baryon-antibaryon partners from interactions $Ξ^{(',*)}_{c}\barΞ^{(*)}$, $Ω^{(*)}_c\barΛ$, $Ω^{(*)}_c\barΣ^{(*)}$, $Λ_c\barΩ$ and $Σ^{(*)}_c\barΩ$. The potential kernels are constructed with the help of effective Lagrangians under SU(3), heavy quark, and chiral symmetries to describe these interactions. To search for possible molecular states, the kernels are inserted into the quasipotential Bethe-Salpeter equation, which is solved to find poles from scattering amplitude. The results suggest that 36 and 24 bound states can be found in the baryon-baryon and baryon-antibaryon interactions, respectively. However, much large values of parameter $α$ are required to produce the bound states from the baryon-antibaryon interactions, which questions the existence of these bound states. Possible coupled-channel effect are considered in the current work to estimate the couplings of the molecular states to the channels considered.

description: Hot giant planets like MASCARA-1 b are expected to have thermally inverted atmospheres, that makes them perfect laboratory for the atmospheric characterization through high-resolution spectroscopy. Nonetheless, previous attempts of detecting the atmosphere of MASCARA-1 b in transmission have led to negative results. In this paper we aim at the detection of the optical emission spectrum of MASCARA-1 b. We used the high-resolution spectrograph PEPSI to observe MASCARA-1 (spectral type A8) near the secondary eclipse of the planet. We cross-correlated the spectra with synthetic templates computed for several atomic and molecular species. We obtained the detection of FeI, CrI and TiI in the atmosphere of MASCARA-1 b with a S/N ~7, 4 and 5 respectively, and confirmed the expected systemic velocity of ~13 km/s and the radial velocity semi-amplitude of MASCARA-1 b of ~200 km/s. The detection of Ti is of particular importance in the context of the recently proposed Ti cold-trapping below a certain planetary equilibrium temperature. We confirm the presence of an the atmosphere around MASCARA-1 b through emission spectroscopy. We conclude that the atmospheric non detection in transmission spectroscopy is due to the high gravity of the planet and/or to the overlap between the planetary track and its Doppler shadow.

description: We explore the relations between physical and orbital properties of planets and properties of their host stars to identify the main observable signatures of the formation and evolution processes of planetary systems. We use a large sample of FGK dwarf planet hosts with stellar parameters derived in a homogeneous way from the SWEET-Cat database to study the relation between stellar metallicity and position of planets in the period-mass diagram. In the second part we use all the RV-detected planets orbiting FGK stars to explore the role of planet-disk and planet-planet interaction on the evolution of orbital properties of planets with masses above 1MJup. We show that planets orbiting metal-poor stars have longer periods than those in metal-rich systems. This trend is valid for masses at least from 10MEarth to 4MJup. Earth-like planets orbiting metal-rich stars always show shorter periods (fewer than 20 days) than those orbiting metal-poor stars. We also found statistically significant evidence that very high mass giants have on average more eccentric orbits than giant planets with lower mass.Finally, we show that the eccentricity of planets with masses higher than 4MJup tends to be lower for planets with shorter periods. Our results suggest that the planets in the P-MP diagram are evolving differently because of a mechanism that operates over a wide range of planetary masses. This mechanism is stronger or weaker depending on the metallicity of the respective system. One possibility is that planets in metal-poor disks form farther out from their central star and/or they form later and do not have time to migrate as far as the planets in metal-rich systems. The trends and dependencies obtained for very high mass planetary systems suggest that planet-disk interaction is a very important and orbit-shaping mechanism for planets in the high-mass domain.

description: Magnetic insulators have proven to be usable as quantum simulators for itinerant interacting quantum systems. In particular the compound (C$_{5}$H$_{12}$N)$_{2}$CuBr$_{4}$ (short (Hpip)$_{2}$CuBr$_{4}$) was shown to be a remarkable realization of a Tomonaga-Luttinger liquid (TLL) and allowed to quantitatively test the TLL theory. Substitution weakly disorders this class of compounds and allows thus to use them to tackle questions pertaining to the effect of disorder in TLL as well, such as the formation of the Bose glass. As a first step in this direction we present in this paper a study of the properties of the related (Hpip)$_{2}$CuCl$_{4}$ compound. We determine the exchange couplings and compute the temperature and magnetic field dependence of the specific heat, using a finite temperature Density Matrix Renormalization group (DMRG) procedure. Comparison with the measured specific heat at zero magnetic field confirms the exchange parameters and Hamiltonian for the (Hpip)$_{2}$CuCl$_{4}$ compound, giving the basis needed to start studying the disorder effects.

description: Projektünk egy olyan új, üzletileg hasznosítható termék/eljárás prototípus fejlesztését és teszte-lését célozza, ami különböző növényi alapanyagok, kiegészítő anyagok, valamint funkcionalitást növelő adalékok használatára épül, és végtermékeiben a tej alapú joghurtra leginkább hasonlító növényi alapú termékeket eredményez, amelyeket a vegán, vegetáriánus, paleo táplálkozású emberek, valamint a tejfehérje érzékenységben és tejcukor intoleranciában szenvedők egyaránt fogyaszthatnak, mindenféle káros, vagy nem kívánt mellékhatás nélkül. Az alábbi célok megvalósításán keresztül terveztük megvalósítani a növényi alapú, fokozott és tudományosan igazolt élettani hatású, környezetkímélő módon előállított termékek kifejlesztését. A tervezett tevékenység keretében részben már alkalmazott részben még növényi alapú joghurt gyártásba nem szereplő növényeket kívánunk alapanyagként megvizsgálni a fejlesztésben való alkalmasság megállapítása céljából: szója, rizs, zab, mandula, kókuszdió, kendermag, kesudió, makadám dió, quinoa. Új, eddig a növényi alapú tejtermék-helyettesítők gyártásában nem alkalmazott techno-lógiát, az ultrahangos homogenizálás alkalmasságát vizsgáljuk meg, amivel nagy hatékonysággal, mérsékelt energiaigénye miatt környezetkímélő módon, a növényi alap-anyagok tápanyag-tartalmát a szokványos főzésen alapuló technikánál sokkal nagyobb mér-tékben megőrizve tudjuk előállítani a fermentációs folyamat kiindulási anyagát jelentő, tej-szerű folyadékot. Bioaktív összetevők (ásványi anyagok, vitaminok, antioxidánsok) felhasználásával célozzuk meg a tej alapú termékek élettani hatását biztosító növényi változatok előállítását. Emésztési modellben vizsgáljuk a kidolgozott kísérleti termékek potenciális élettani hatását, melyhez hasonló vizsgálatot a jelenleg piacon lévő termékek esetében nem végeznek, így azokra vonatkozóan nem áll rendelkezésre olyan információ, ami a várható hasznosulás mértékét igazolná.
