description: Nell’ottica di un processo di insegnamento/apprendimento proteso allo sviluppo delle competenze comunicative, come è quello attuale, le strategie sviluppate dagli alunni per interiorizzare le espressioni linguistiche possono costituire un valido supporto per consentire loro di acquisire maggiore consapevolezza e scioltezza linguistica. In che modo è possibile aiutare degli allievi con delle difficoltà di apprendimento ad esprimersi in maniera efficace? Questo studio propone un esempio di tre strategie di apprendimento che vanno in questa direzione. I risultati ottenuti dimostrano che le strategie più efficaci sono quelle dell’interiorizzazione progressiva e dell’anticipazione dei contenuti. Inoltre, l’intero percorso ha sensibilizzato gli allievi all’apprendimento per superare gli ostacoli iniziali riscontrati al fine di sviluppare le proprie competenze. Relatore: Gé Stoks.

description: We study CP violation and the contribution of the strong pion-pion interactions in the three-body B+- --> pi+- pi-+ pi+- decays within a quasi two-body QCD factorization approach. The short distance interaction amplitude is calculated in the next-to-leading order in the strong coupling constant with vertex and penguin corrections. The meson-meson final state interactions are described by pion non-strange scalar and vector form factors for the S and P waves and by a relativistic Breit-Wigner formula for the D wave. The pion scalar form factor is calculated from a unitary relativistic coupled-channel model including pi pi, Kbar K and effective (2pi)(2pi) interactions. The pion vector form factor results from a Belle Collaboration analysis of tau- --> pi- pi0 nu_tau data. The recent B+- --> pi+- pi-+ pi+- BABAR Collaboration data are fitted with our model using only three parameters for the S wave, one for the P wave and one for the D wave. We find not only a sizable contribution of the S wave just above the pi pi threshold but also under the rho(770) peak a significant interference, mainly between the S and P waves. For the B to f_2(1270) transition form factor, we predict F^{Bf_2}(m_π^2)=0.098+-0.007. Our model yields a unified unitary description of the contribution of the three scalar resonances f_0(600), f_0(980) and f_0(1400) in terms of the pion non-strange scalar form factor.

description: We demonstrate terahertz (THz) imaging and spectroscopy of a 15x15-mm^2 single-layer graphene film on Si using broadband THz pulses. The THz images clearly map out the THz carrier dynamics of the graphene-on-Si sample, allowing us to measure sheet conductivity with sub-mm resolution without fabricating electrodes. The THz carrier dynamics are dominated by intraband transitions and the THz-induced electron motion is characterized by a flat spectral response. A theoretical analysis based on the Fresnel coefficients for a metallic thin film shows that the local sheet conductivity varies across the sample from σs = 1.7x10^-3 to 2.4x10^-3 Ω^-1 (sheet resistance, ρs = 420 - 590 Ω/sq).

description: We assess the importance of final state interactions in $D^+ \rar K^- \p^+ \p^+$, stressing the consistency between two- and three-body interactions. The basic building block in the calculation is a $Kπ$ amplitude based on unitarized chiral perturbation theory and with parameters determined by a fit to elastic LASS data. Its analytic extension to the second sheet allows the determination of two poles, associated with the $\k$ and the $K^*(1430)$, and a representation of the amplitude based on them is constructed. The problem of unitarity in the three-body system is formulated in terms of an integral equation, inspired in the Faddeev formalism, which implements a convolution between the weak vertex and the final state hadronic interaction. Three different topologies are considered for the former and, subsequently, the decay amplitude is expressed as a perturbation series. Each term in this series is systematically related to the previous one and a re-summation was performed. Remaining effects owing to single and double rescattering processes were then added and results compared to FOCUS data. We found that proper three-body effects are important at threshold and fade away rapidly at higher energies. Our model, based on a vector weak vertex, can describe qualitative features of the modulus of the decay amplitude and agrees well with its phase in the elastic region.

description: We present a cold atom gravimeter operating with a sample of Bose-condensed Rubidium-87 atoms. Using a Mach-Zehnder configuration with the two arms separated by a two-photon Bragg transition, we observe interference fringes with a visibility of 83% at T=3 ms. We exploit large momentum transfer (LMT) beam splitting to increase the enclosed space-time area of the interferometer using higher-order Bragg transitions and Bloch oscillations. We also compare fringes from condensed and thermal sources, and observe a reduced visibility of 58% for the thermal source. We suspect the loss in visibility is caused partly by wavefront aberrations, to which the thermal source is more susceptible due to its larger transverse momentum spread. Finally, we discuss briefly the potential advantages of using a coherent atomic source for LMT, and present a simple mean-field model to demonstrate that with currently available experimental parameters, interaction-induced dephasing will not limit the sensitivity of inertial measurements using freely-falling, coherent atomic sources.

description: This work is devoted to the study of changes in the structure of two-layer silicon-carbon films on glass under electron irradiation. It was shown that irradiation with 11 keV electrons with a dose of 30 mC/cm2 of a two-layer silicon-carbon film leads to the formation of crystalline silicon carbide of different polytypes. Also, under irradiation, amorphous films of silicon and carbon crystallize locally.

description: We have discovered a large number of circular and elliptical shells at 24 microns around luminous central sources with the MIPS instrument on-board the Spitzer Space Telescope. Our archival follow-up effort has revealed 90% of these circumstellar shells to be previously unknown. The majority of the shells is only visible at 24 microns, but many of the central stars are detected at multiple wavelengths from the mid- to the near-IR regime. The general lack of optical counterparts, however, indicates that these sources represent a population of highly obscured objects. We obtained optical and near-IR spectroscopic observations of the central stars and find most of these objects to be massive stars. In particular, we identify a large population of sources that we argue represents a narrow evolutionary phase, closely related or identical to the LBV stage of massive stellar evolution.

description: Surface-located and secreted virulence factors of the Gram-positive bacterial pathogen Staphylococcus aureus are key drivers for infection of the human host. Proteolytic enzymes may contribute to virulence by breaking primary barriers and host immune defenses. Therefore, the objective of our present study was to chart the contributions of different proteases to S. aureus virulence, and to assess their roles in shaping the staphylococcal surface proteome (the ‘surfacome’) and extracellular proteome (the ‘secretome’). To this end, we applied 12 protease mutants of the S. aureus USA300 lineage. Four mutants lacking the metalloprotease aureolysin (Aur), the cysteine proteases staphopain A (ScpA) and SspB, or the serine protease SspA displayed enhanced cytotoxicity towards human lung epithelial cells, showing that they serve to suppress virulence. Profiling of the surfacomes and secretomes of the four mutants allowed correlation of their increased cytotoxicity to altered virulence factor profiles. Furthermore, enhanced levels of virulence factors were detected in the mutants’ surfacomes, which was shown to be relevant as all four mutants displayed enhanced lung epithelial cell invasion. Enhanced levels of cytoplasmic and membrane proteins in the mutant’s surfacomes showed that Aur, ScpA, SspA and SspB set limits to autolysis by reducing the levels of peptidoglycan hydrolases. We conclude that Aur, ScpA, SspA and SspB have key roles in shaping the surfacome and secretome of S. aureus, thereby controlling the virulence of this major pathogen. This implies that novel antimicrobial agents or vaccines should not target these proteases.

description: We have discovered ultraviolet halos extending as far as 5° around four (of six) bright UV stars using data from the GALEX satellite. These halos are due to the scattering of the starlight from nearby thin, foreground dust clouds. We have placed limits of 0.58 $\pm$ 0.12 and 0.72 $\pm$ 0.06 on the phase function asymmetry factor (g) and limits on the albedo of 0.10 $\pm$ 0.05 and 0.26 $\pm$ 0.10 in the FUV (1521 Å) and NUV (2320 Å) bands, respectively. We suggest that these halos are a common feature around bright stars and may be used to explore the scattering function of interstellar grains at small angles.

description: Il tema della ricerca-azione riguarda l’insegabilità e apprendibiltà delle strategie di comunicazione. In letteratura esse vengono definite strategie che mirano al miglioramento dell’abilità di interagire oralmente, ossia nell’ambito di quella che viene definita dal Common European Framework of Reference for Languages (Council of Europe, 2001) spoken intarcation (p. 26). Questa piccola ricerca mira, malgrado i limiti dettati dal tempo e dalle condizioni, a verificare se, in seguito a un ciclo d’istruzione, vi è, in un gruppo attitudinale di allievi di IV media, un miglioramento della spoken interaction nell’ambito del tedesco L2. Il campione è composto da 22 allievi, suddivisi in base a determinate caratteristiche: sesso, mese di nascita, l’essere mono- o bilingue e profitto generale. Alla domanda di ricerca principale se ne affianca un’altra: chi beneficia maggiormente di tale ciclo d’istruzione? Allievi con quali delle caratteristiche succitate? Il ciclo ha coperto un periodo di tre mesi ed è stato modellato sul cycle of strategy instruction di Harris (2001, pp. 22-24). È emerso che ad aver tatto maggior vantaggio da esso sono stati allievi con una delle seguenti caratteristiche: di sesso femminile, con profilo scolastico debole e nati nel secondo semestre solare. Tuttavia, al di là di questo dato che va preso con molta cautela, è stato mostrata la ricaduta, non solo a livello di “quantità” di apprendimento (misurata attraverso un pre- e da un post-test), ma anche di consapevolezza della funzione e dell’utilità delle strategie di comunicazione per ogni singolo allievo, rilevata attraverso due questionari a risposta aperta. Data l’esiguità del campione, sembrano anzi proprio questi dati a fornire informazioni più preziose ai docenti desiderosi di sperimentare con le loro classi un ciclo d’istruzione di questo tipo.

description: We establish new fractal properties for superprocess densities. Consider the density of super-Brownian motion in one dimension at a fixed time. We construct a random measure supported on the boundary of the zero set of the density, which we call the boundary local time, and prove that it is locally non-degenerate, in the sense that it almost surely has positive mass on every neighbourhood of the boundary of the support. We then use the boundary local time to give an almost sure lower bound on the Hausdorff dimension of the boundary of the zero set, confirming a conjecture of Mueller et al. [69], whose work on this problem motivated ours. The Hausdorff dimension is characterized in terms of the lead eigenvalue of a certain killed Ornstein-Uhlenbeck operator which also appears in the construction of the boundary local time. The proof of local non-degeneracy includes a novel analysis of the density near the right endpoint of its support, including a new bound on the expected mass in a neighbourhood of the endpoint. We then consider the density of (α, β)-superprocess in dimension d with α ∈ (0, 2), β ∈ (0, 1], and βd < α. A classical result called instantaneous propagation asserts that, at a fixed time, the density has positive mass on any open set almost surely when conditioned on survival. We give general conditions under which the integral the density against a measure μ is positive almost surely when conditioned on survival. In particular, we show that this is determined by the relationship between the dimension of the measure, which we define in two ways, and a critical parameter determined by α, β and d. When the density does not charge μ almost surely, we obtain upper and lower bounds on the probability that it does so. In both cases our results correspond to new existence and non-existence results for solutions to the partial differential equation which is dual to the process. In the regime where the density is continuous and positive at a fixed point almost surely, we prove that the density function is strictly positive.

description: Parallel zur Wissenschaft werden in der Wirtschaft kontinuierlich Daten erhoben und mit Methoden und Standards gearbeitet, welche für mehrere Wissenschaftsdisziplinen innerhalb der NFDI von höchster Relevanz sind. Umgekehrt verfügt aber auch die Wissenschaft über Daten und methodische Kompetenzen, die für die Wirtschaft bedeutend sind. Während mehrere Konsortien zurzeit unabhängig voneinander spezifische und partnerabhängige Wirtschaftskooperationen und Datenintegrations-modelle pflegen, wurden Akteure aus der Wirtschaft bisher noch nicht systematisch in die NFDI eingebunden. Eine ganzheitliche Betrachtung der Zusammenarbeit über alle Bereiche der NFDI hinweg bietet hier das Potenzial, eine stärkere Außenwirkung, höhere Effizienz und bessere Umsetzbarkeit solcher Kooperationen aufgrund klarer Abstimmung und Koordination untereinander zu erzielen. So können über die bisher bestehenden Interaktionen hinaus neue Mehrwerte für alle Akteure geschaffen werden. Die Sektion Industry Engagement befasst sich deshalb mit der übergreifenden Gestaltung von Kooperationen zwischen der Wirtschaft und den NFDI-Konsortien, Basisdiensten und weiteren Sektionen. Das übergreifende Ziel ist dabei, den bereits durch die NFDI geschaffenen gesellschaftlichen Mehrwert um eine koordinierte Zusammenarbeit mit der Wirtschaft zu erweitern. Dies schließt u.a. die Schaffung einer gemeinsamen Austauschplattform zwischen Wirtschaft und Wissenschaft, die Identifikation und Konkretisierung von übergreifenden Problemfeldern, ggf. bereits eine erste gemeinsame Erarbeitung von Lösungsräumen sowie eine Vereinheitlichung und Vereinfachung von Kooperationsformen innerhalb der NFDI ein. Um diese Ziele zu erreichen, plant die Sektion eine stetige Bedarfsermittlung in Bezug auf die Bewältigung aktueller Herausforderungen aller wirtschaftlichen und wissenschaftlichen Akteure, um daraus gemeinsame Themen mit hohem gesellschaftlichem Mehrwert abzuleiten, ggf. erste Lösungsräume und dafür in Form und Umfang geeignete Kooperationsmodelle zu entwickeln und aus den Ergebnissen Empfehlungen und Beratungsangebote für die NFDI abzuleiten. Bis Dezember 2024 soll so ein intern abgestimmtes und im Einklang mit Stakeholdern aus der Wirtschaft stehendes Vorgehen zu gemeinsamen Kooperationen erreicht werden. Dabei sollen auch bestehende Sektionen der NFDI (z.B. Base4NFDI und Ethical, Legal and Social Aspects) sowie international agierende Verbände, Kompetenzzentren und Institutionen an der Schnittstelle zur Wirtschaft aktiv miteinbezogen werden.
Effect of phase fluctuation and dephasing on the dynamics of entanglement generation in a correlated emission laser

description: A detailed study of the effects of phase fluctuation and dephasing on the dynamics of the entanglement generated from a coherently pumped correlated emission laser is presented. It is found that the time evolution of the entanglement is significantly reliant on the phase fluctuation and dephasing, particularly, at early stages of the lasing process. In the absence of external driving radiation, the degree of entanglement and intensity turns out to attain a maximum value just before starting to exhibit oscillation which dies at longer time scale. However, in case the driving mechanism is on, the oscillatory nature disappears due to the additional induced coherent superposition and the degree of entanglement would be larger at steady state. Moreover, the degree of entanglement as predicted by the logarithmic negativity and the Duan-Giedke-Cirac-Zoller criteria exhibits a similar nature when there is no driving radiation, although such a trend is eroded with increasing strength of the pumping radiation at longer time scale. The other important aspect of the phase fluctuation and dephasing is the possibility of relaxing the time at which the maximum entanglement is detected.

description: We propose a novel framework in which the observed baryon and dark matter abundances are simultaneously generated via the Affleck-Dine mechanism. In its simplest realization, Affleck-Dine cogenesis is accomplished by a single superpotential operator and its A-term counterpart. These operators explicitly break B-L and X, the dark matter number, to the diagonal B-L+X. In the early universe these operators stabilize supersymmetric flat directions carrying non-zero B-L and X, and impart the requisite CP violation for asymmetry generation. Because B-L+X is preserved, the resulting B-L and X asymmetries are equal and opposite, though this precise relation may be relaxed if B-L and X are violated separately by additional operators. Our dark matter candidate is stabilized by R-parity and acquires an asymmetric abundance due to its non-zero X number. For a dark matter mass of order a few GeV, one naturally obtains the observed ratio of energy densities today, Omega_{DM}/Omega_B \sim 5. These theories typically predict macroscopic lifetimes for the lightest observable supersymmetric particle as it decays to the dark matter.

description: Wind turbine blade undergoes variable static and dynamic during its actual life cycle. Modern wind turbine blades are designed to withstand various dynamic loading conditions. Wind turbine blades undergoes failure in combination of flap wise and edge wise. For optimum design of wind turbine blades, there should be proper selection of materials for turbine blades. Wind turbine blades are manufactured by using composite materials such as epoxy resin, and various other carbon fiber reinforced plastics. In this paper wind turbine blade prototype is analyzed using finite element analysis (ANSYS) for various loading conditions.

description: Il mio progetto di ricerca indaga le differenze e le similitudini tra neo-docenti e docenti con esperienza riguardo all’ambito creativo alla scuola dell’infanzia (faccio riferimento alla dimensione grafico-pittorica e plastico-manipolativa descritte negli Orientamenti programmatici per la scuola dell’infanzia del Cantone Ticino). La mia ricerca è prettamente di tipo qualitativo, ho proceduto svolgendo delle interviste semi strutturate che ho poi analizzato formando delle categorie e sintetizzando i dati in tabelle, il tutto ispirandomi alla grounded theory. I risultati più rilevanti della mia ricerca per l’integrazione dei neo-docenti sono: l’opinione comune degli intervistati riguardo all’utilità di hobby e passioni creative e/o artistiche, il fatto di percepire meno il giudizio dei colleghi relativo alle attività creative svolte in sezione, rispetto ad altri ambiti e l’importanza attribuita alla collaborazione da parte dei neo-docenti. Questo lavoro ha pure permesso di mettere in evidenza che vi sono delle similitudini, tra neo-docenti e docenti con esperienza, riguardo allo svolgimento concreto delle attività, alle finalità e motivazioni legate ad esse. Un dato invece che differenzia le due categorie, è la maggior passione per l’arte e le attività legate ad essa, in sezione, espressa dai docenti con esperienza. Relatore: Silvio Canevascini

description: Nel presente lavoro di ricerca ho programmato, e in parte realizzato, un itinerario di Educazione allo Sviluppo Sostenibile (ESS) volto a sensibilizzare gli allievi di una sezione di SI sul tema dello spreco alimentare. L’obiettivo era quello di comprendere quale valore i bambini dessero al cibo e, attraverso le diverse attività, far sviluppare un pensiero sostenibile capace di diminuire sempre più i rifiuti alimentari. Mediante la presenza di un laboratorio in sezione, l’analisi delle rappresentazioni grafiche e del linguaggio dei bambini con il software IRaMuTeQ, la ricerca ha dimostrato che, nonostante il percorso non sia stato concluso, i bambini della SI possiedono le basi per un pensiero sostenibile. Le uscite sul territorio, le esperienze dirette nel laboratorio e le discussioni in sezione hanno permesso al gruppo-classe di indirizzare sempre più le proprie scelte sul tema della sostenibilità. Non avendo potuto terminare il percorso a causa della chiusura delle scuole per l’emergenza Covid19 ho ampliato la mia ricerca, analizzando come viene percepita la didattica volta a sensibilizzare sullo spreco alimentare nei profili di competenza presenti nel Piano di Studio, nel concordato HarmoS e proposti da éducation21. Nonostante l’ESS, e quindi lo spreco alimentare, siano percepiti come temi da proporre principalmente nel 3° ciclo, i bambini hanno dimostrato che è possibile trattare questo tema anche alla SI, controllando saperi concreti e collegabili alle esperienze vissute in sezione, lontani però dai saperi più “adulti” presenti nei programmi.

description: This study examines the impact of digital transformation on work-related stress and employee engagement in Moroccan universities, while also exploring the role of organizational resources in mitigating these effects. A quantitative approach was adopted, utilizing a questionnaire survey conducted among 300 university teachers and students from both public and private universities. Structural Equation Modeling (PLS-SEM) was employed to analyze relationships between digital transformation, work-related stress, and employee engagement. The findings indicate that digital transformation increases work-related stress, which negatively affects employee engagement. However, the presence of strong organizational resources, such as training and managerial support, significantly reduces this negative effect. Digital transformation poses both challenges and opportunities in higher education. While it enhances accessibility and efficiency, it also contributes to stress and disengagement among employees. Universities must adopt supportive organizational measures to minimize these adverse effects and sustain employee engagement.
On spherical type singularities in integrable systems

description: This thesis is devoted to the study of a relatively new class of integrable systems, characterized by singular fibers in the Lagrangian fibration that one might describe as being of ‘spherical type’ - that is they are smooth submanifolds diffeomorphic to product of spheres of any dimension, although possibly quotient by the action of some finite group. In these systems we have globally defined and continuous but not necessarily smooth action variables. These fibers of special interest appear as fibers over points where the actions are not smooth.We study certain examples of these systems. For geodesic flow on the sphere S^n (with integrals associated to Vilenkin’s polyspherical coordinates) we give a complete description of the moment cone as well as a topological description of all singular fibers.We then study the system of bending flows on polygon spaces, proving various results centred on describing the topology of fibers over certain simplicial vertices of the moment polytope.Finally, we verify that geodesic flow on S^2 can be used as a local model for a neighbourhood of the S^2 singular fibers appearing in systems of bending flows on spaces of pentagons.

description: We prove three facts about intrinsic geometry of surfaces in a normed (Minkowski) space. When put together, these facts demonstrate a rather intriguing picture. We show that (1) geodesics on saddle surfaces (in a space of any dimension) behave as they are expected to: they have no conjugate points and thus minimize length in their homotopy class; (2) in contrast, every two-dimensional Finsler manifold can be locally embedded as a saddle surface in a 4-dimensional space; and (3) geodesics on convex surfaces in a 3-dimensional space also behave as they are expected to: on a complete strictly convex surface, no complete geodesic minimizes the length globally.

The produced useful energy for proposed system is 4.74 kWh/kWp/day with performance ratio of 79.60%. As far as losses from the system are considered it is about system losses comprises of 0.15 kWh/kWp/day and collection losses is 1.07 kWh/kWp/day respectively.
Continuous Hawking-Page transitions in Einstein-scalar gravity

description: We investigate continuous Hawking-Page transitions in Einstein's gravity coupled to a scalar field with an arbitrary potential in the weak gravity limit. We show that this is only possible in a singular limit where the black-hole horizon marginally traps a curvature singularity. Depending on the subleading terms in the potential, a rich variety of continuous phase transitions arise. Our examples include second and higher order, including the Berezinskii-Kosterlitz-Thouless type. In the case when the scalar is dilaton, the condition for a continuous phase transition lead to (asymptotically) linear-dilaton background. We obtain the scaling laws of thermodynamic functions, as well as the viscosity coefficients near the transition. In the limit of weak gravitational interactions, the bulk viscosity asymptotes to a universal constant, independent of the details of the scalar potential. As a byproduct of our analysis we obtain a one-parameter family of kink solutions in arbitrary dimension d that interpolate between AdS near the boundary and linear-dilaton background in the deep interior. The continuous Hawking-Page transitions found here serve as holographic models for normal-to superfluid transitions.

description: Recent progress of lattice QCD study of nuclear forces (potentials) is reviewed. Scattering phase shift is an important observable for two particle system. In lattice QCD, phase shifts are calculated from long distance behavior of Bethe-Salpeter (BS) wave functions by Luescher's finite volume method. For applications to nuclear physics of multi-nucleon system, it is more advantageous to convert the information of phase shifts in the form of potentials. We therefore extend the method so as to generate the potentials from BS wave functions. These potentials are faithful to scattering phase shift by construction, because they can reproduce BS wave functions in which the information of phase shift is embeded in the long distance part.The method was first applied to the central potential in NN system. It is now applied to many objects, such as tensor potential, hyperon potentials, energy dependence of nuclear potentials, and investigations of the repulsive core at short distance.

Investigating the role of transcriptional coactivator MED15 in beta cell maturation
Creators: name: Kadhim, Alexandre Zacharie
Publisher: name: University of British Columbia

description: The Mediator complex, a coregulator required for RNA pol II activity, interacts with specific transcription factors through its distinct subunits. These interactions promote the expression of defined gene sets both during development and for tissue homeostasis. Transcriptional regulatory networks are critical for the development and function of pancreatic β-cells. To date, few studies examining how transcription factors interact with co-activators, such a Mediator, have been performed in the pancreas. Tail module subunit MED15 is highly expressed in nascent β-cells and required for lipid metabolism, various stress responses, and TGF-β signalling, all of which are important for β-cell function. As such, we hypothesized that MED15 plays a role in β-cells. We found MED15 to be expressed during mouse pancreatogenesis and in mature β-cells. Expression of MED15 was impaired in human T2D islets suggesting it is important for mature β-cell function. After generating a β-cell specific knockout mouse (IM15KO), we observed defects in maturation as assessed by loss of β-cell maturation markers UCN3, MAFA, and GLUT2. In agreement with reduced GLUT2 expression, IM15KO cells had impaired glucose uptake and reduced glucose-stimulated insulin secretion, the hallmark process of β-cell maturation. ChIP-seq analysis determined that MED15 is bound to key GSIS related genes and Co-IP found transcription factors NEUROD1 and NKX6-1 to bind MED15. As the pancreas contains among the highest levels of Zn²⁺ in the body, we also found a role for MED15 in heavy metal stress response. Through this thesis, I provide evidence of the importance of Mediator in β-cell maturation and demonstrate an additional layer of control that modulates transcription factor function. A greater understanding of how Mediator and MED15 regulate β-cell maturation could help refine the generation of cell-based therapies for diabetes.

description: Bicontinuous, interfacially jammed emulsion gels (bijels) represent a class of soft solid materials in which interpenetrating domains of two immiscible fluids are stabilized by an interfacial colloidal monolayer. Such structures can be formed by arrested spinodal decomposition from an initially single-phase colloidal suspension. Here we explore by lattice Boltzmann simulation the possible effects of using magnetic colloids in bijels. This may allow additional control over the structure, during or after formation, by application of a magnetic field or field gradient. These effects are modest for typical parameters based on the magnetic nanoparticles used in conventional ferrofluids, although significantly larger particles might be appropriate here. Field gradient effects, which are cumulative across a sample, could then allow a route for controlled breakdown of bijels as they do for particle-stabilized droplet emulsions.

description: The dairy industry is one of the major energy consuming sectors in India. The various processes in dairy industry include pasteurization, cream separation, homogenization, chilling of milk and packaging of milk and value-added products. Currently, the thermal and electrical demand required for various dairy processes is satisfied by conventional fuels like furnace oil, coal, natural gas and electricity. The case study undergone at Karimnagar Milk Producers Company Ltd (KMPCL) uses coal as a conventional fuel for boiler, which provides steam to various processes in dairy. The proposed Photovoltaic system array simulated at KMPCL can provide an electrical demand for homogenizer and other basic electrical equipment’s.
