description: High resolution spectral observations of the polar EF Eridani obtained in a low state with X-Shooter revealed narrow emission lines from the irradiated secondary. The lines were most prominent in the near-IR Ca2-triplet, the more intensive Halpha line had additional emission likely originating from an accretion stream. The lines with a radial velocity amplitude, K2' = 385 +- 4 kmps, serve as tracer of the otherwise unseen companion. The mass function implies a massive white dwarf with Mwd > 0.65 Msun at 3sigma confidence, and a short distance to the binary, d ~ 111 pc (<145pc at 3sigma confidence). The spectral energy distribution from the UV to the IR together with the high mass ratio gives further strong evidence of EF Eri being a post period-minimum object with M2 < 0.06 Msun

The modification of chimeric antigen receptor T cells to overcome immune suppression mediated by indoleamine 2,3-dioxygenase
Creators: name: May, Christopher Galen
Publisher: name: University of British Columbia
Year: 2024

description: Chimeric antigen receptor (CAR) T cells are regarded as a major breakthrough for treating hematological malignancies. Through expression of a receptor comprising an extracellular antigen-binding domain and intracellular stimulatory domains, CAR T cells can be re-directed to target cells expressing the antigen of choice where they are activated to proliferate and kill their targets. Despite representing a major advancement in the treatment of “liquid” tumours, the success of CAR T cells in solid tumours has been hampered in part by the immunosuppressive tumour microenvironment. Tumours form a complex network of cells and signaling molecules that promote tumour growth while suppressing the immune response. One of these mechanisms of immunosuppression is indoleamine 2,3-dioxyganse (IDO). IDO degrades tryptophan into a set of immunosuppressive metabolites called kynurenines. Through these actions, IDO activates suppressive immune cells while inhibiting anti-tumour immunity. In CAR T-cell therapy, IDO expression can suppress T-cell mediated killing and compromise treatment efficacy. The aim of this thesis is to enhance the ability of CAR T cells to contend with IDO-mediated immunosuppression in the tumour microenvironment. This engineering strategy involves the enzymatic degradation of suppressive kynurenines, which first requires knowledge of the specific kynurenines involved. Herein I show that of all kynurenines, kynurenine itself most strongly suppresses CAR T cells through the aryl hydrocarbon receptor, and I demonstrate the ability of T cells expressing kynureninase (KYNase) to degrade kynurenine in vitro. I outline the optimization of a model system to assess IDO-mediated immunosuppression of human CAR T cells in vivo, and use this system to evaluate the therapeutic effect of KYNase modification. I show that, while KYNase expression is ineffective at rescuing human CAR T-cell suppression in a subcutaneous tumour model in vivo, the modification of the CAR itself may influence its ability to withstand the immunosuppressive milieu produced by IDO. Furthermore, I identify the solvents used in in vitro assays as a possible confounding factor that may influence the interpretation of decades of research into kynurenine. This thesis contributes towards a better appreciation of the variability in IDO-mediated immunosuppression in vitro and in vivo, between species, and across diverse model systems.
title: Neither absence nor excess of FGF23 disturbs fetal phosphate metabolism in mice until after birth
Creators: name: Ma, Yue
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Fibroblast growth factor 23 (FGF23) plays an important role in maintaining phosphate homeostasis in adults largely though actions on the kidneys to excrete phosphate and reduce calcitriol. However, whether FGF23 is essential in maintaining phosphate homeostasis in fetuses had been largely unknown prior to my Ph.D. project, which hypothesized that FGF23 was important in regulating not only fetal serum phosphate and skeletal development, but also placental phosphate transport. However, studies in Phex null fetuses showed that excess FGF23 did not disturb any phosphate parameter or placental phosphate transport. Although the expression of Cyp24a1 was increased in the null placenta and kidneys and the expression of Klotho was decreased in the null kidneys, these changes did not disturb any physiological parameter related to phosphate, which suggests that FGF23 is not important in fetal phosphate regulation. Previous studies in Fgf23 null fetuses showed FGF23 absence did not alter fetal phosphate parameters, placental phosphate transport or skeletal development. These results led to my hypothesis that other FGF members might compensate for FGF23 loss by acting on the FGFR/Klotho receptor complex. However, studies in Klotho null fetuses showed that serum FGF23 was normal and that they had a similar phenotype as Fgf23 nulls – which rejected my hypothesis. Previous studies showed that Pth null fetuses developed hyperphosphatemia. I then studied Pth/Fgf23 double knockout (DKO) fetuses to determine if absence of FGF23 would potentiate hyperphosphatemia in Pth nulls. The results showed that DKO had the same elevation in serum phosphate as Pth nulls and there were no skeletal mineral content changes between the two genotypes either. I finally examined the postnatal time course of phosphate metabolism in neonatal Fgf23 nulls, Klotho nulls, and Phex nulls, respectively. The results showed Fgf23 nulls and Klotho nulls were normal at birth, but developed hyperphosphatemia, increased renal gene expression of NaPi2a and NaPi2c, and increased renal phosphate reabsorption between 5 and 7 days later. In contrast, excess FGF23 exerted effects in Phex nulls within 12 hours after birth, with the development of hypophosphatemia, reduced renal expression of NaPi2a and NaPi2c, and decreased renal phosphate reabsorption. In conclusion, my Ph.D. project suggests FGF23 is not an important regulator of fetal phosphate metabolism.

title: Contribution of surface flux and ocean heat transport convergence to the interannual variability of the Labrador Sea
Creators: name: Madan, Gaurav
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The heat content and convergence of the heat flux transport (CHFT) in the ocean region 65ᴼW-40ᴼW, 45ᴼN-65ᴼN is studied based on in-situ observations of ocean temperature and the reanalaysis of surface flux for the period from 1993 to 2018. This region includes the Labrador Sea, the area of North Atlantic Current and Newfoundland Basin. The CHFT is computed from the equations of the tendency of heat contents for the surface (0-150 m depth), intermediate (150-2000 m depth), and deep (below 2000 m) layers and the whole ocean column. The highest interannual variability of CHFT is observed in the regions of the Newfoundland Basin and North Atlantic Current. The CHFT in the first region is influenced by the influx of sea-ice from the Northern Labrador Sea. The interannual variability of the CHFT in the second region represents the year-to-year change in the contribution of the ocean transport to the heat budget by the extension of Gulf Stream in the Subpolar North Atlantic. The CHFT in the central, eastern, northwestern, and northeastern sub-regions of the Labrador Sea were found to be highly correlated (r>0.7). There is a very weak correlation between the CHFT in these regions and the CHFT in the Newfoundland Basin and North Atlantic Current.

description: The surprising thing is that arising almost 50 years ago from the linear sigma model (LSM) with spontaneously broken chiral symmetry, the light scalar meson problem has become central in the nonperturbative quantum chromodynamics (QCD) for it has been made clear that LSM could be the low energy realization of QCD. First we review briefly signs of four-quark nature of light scalars. Then we show that the light scalars are produced in the two photon collisions via four-quark transitions in contrast to the classic $P$ wave tensor $q\bar q$ mesons that are produced via two-quark transitions $γγ\to q\bar q$. Thus we get new evidence of the four-quark nature of these states.

description: Raman spectroscopy is a fast, non-destructive means to characterize graphene samples. In particular, the Raman spectra show a significant dependence on doping. While the change in position and width of the G peak can be explained by the non-adiabatic Kohn anomaly at $Γ$, the significant doping dependence of the 2D peak intensity has not been explained yet. Here we show that this is due to a combination of electron-phonon and electron-electron scattering. Under full resonance, the photogenerated electron-hole pairs can scatter not just with phonons, but also with doping-induced electrons or holes, and this changes the intensity. We explain the doping dependence and show how it can be used to determine the corresponding electron-phonon coupling. This is higher than predicted by density-functional theory, as a consequence of renormalization by Coulomb interactions.

Adapting to sensorimotor delay in the control of standing balance
Creators: name: Liu, Xiyao
Publisher: name: University of British Columbia
Year: 2024

description: When balancing upright, humans must differentiate self-motion generated by their own motor commands from that induced by external events. This dynamic process is required to generate balance-correcting responses and must take into account uncertainty in the sensorimotor control of balance induced by sensorimotor noise as well as sensing and actuation delays. In the present study, I characterized how humans adapt their control of standing balance when faced with uncertainty associated with sensorimotor delays. Twenty-two young healthy adults stood upright individually in a robotic balance simulator that allowed me to manipulate the delays between their self-generated ankle torques and resulting whole-body motion. Participants balanced in the anteroposterior direction with baseline delays (10ms) and adaption to imposed delays of 250ms for 20 minutes. I observed that the introduction of sensorimotor delays destabilized how participants balanced upright, most falling frequently within the first 5 minutes. Participants also exhibited an increase in lower leg muscles activation (4-12 times compared to pre-adaptation), and agonist-antagonist co-contractions (5-13 times compared pre-adaptation), immediately after the delay was introduced. Through exposure to the imposed delays, participants adapted their control of balance by minimizing whole-body motion variability from 10.64 ± 3.47 to 1.19± 0.64 [°/s]². The sway velocity variance at the end of the adaptation was 15 times greater than post-adaptation quiet standing. Similarly, through the adaptation, the gradual decrease in the muscle activation and muscle co-contraction was also observed. When removing the imposed delay (post-adaptation period), the sway variance in the participants whole-body motion quickly return to pre-adaptation values. Muscle activation and co-activation at post-adaptation was also lower at the post-adaptation trials compared to those observed during the late adaptations. The present findings show that humans adapt their control of balance by increasing muscle activation and co-contraction when faced with imposed sensorimotor delays and exhibit minimal (or brief) after-effects in motion variability when an imposed delay is removed. The results from this study provide initial insights to help us understand how humans adapt to the changes in sensorimotor delays they may experience throughout their lifespan or encounter a neurological disorder.

description: Electron spin relaxation in bulk III-V semiconductors is investigated from a fully microscopic kinetic spin Bloch equation approach where all relevant scatterings, such as, the electron--nonmagnetic-impurity, electron-phonon, electron-electron, electron-hole, and electron-hole exchange (the Bir-Aronov-Pikus mechanism) scatterings are explicitly included. The Elliot-Yafet mechanism is also fully incorporated. This approach offers a way toward thorough understanding of electron spin relaxation both near and far away from the equilibrium in the metallic regime. The dependence of the spin relaxation time on electron density, temperature, initial spin polarization, photo-excitation density, and hole density are studied thoroughly with the underlying physics analyzed. In contrast to the previous investigations in the literature, we find that: (i) In $n$-type materials, the Elliot-Yafet mechanism is {\em less} important than the D'yakonov-Perel' mechanism, even for the narrow band-gap semiconductors such as InSb and InAs. (ii) The density dependence of the spin relaxation time is nonmonotonic and we predict a {\em peak} in the metallic regime in both $n$-type and intrinsic materials. (iii) In intrinsic materials, the Bir-Aronov-Pikus mechanism is found to be negligible compared with the D'yakonov-Perel' mechanism. We also predict a peak in the temperature dependence of spin relaxation time which is due to the nonmonotonic temperature dependence of the electron-electron Coulomb scattering in intrinsic materials with small initial spin polarization. (iv) In $p$-type III-V semiconductors, ...... (the remaining is omitted here due to the limit of space)

description: We present SIBELIUS-DARK, a constrained realisation simulation of the local volume to a distance of 200~Mpc from the Milky Way. SIBELIUS-DARK is the first study of the \textit{Simulations Beyond The Local Universe} (SIBELIUS) project, which has the goal of embedding a model Local Group-like system within the correct cosmic environment. The simulation is dark-matter-only, with the galaxy population calculated using the semi-analytic model of galaxy formation, GALFORM. We demonstrate that the large-scale structure that emerges from the SIBELIUS constrained initial conditions matches well the observational data. The inferred galaxy population of SIBELIUS-DARK also match well the observational data, both statistically for the whole volume and on an object-by-object basis for the most massive clusters. For example, the $K$-band number counts across the whole sky, and when divided between the northern and southern Galactic hemispheres, are well reproduced by SIBELIUS-DARK. We find that the local volume is somewhat unusual in the wider context of $Λ$CDM: it contains an abnormally high number of supermassive clusters, as well as an overall large-scale underdensity at the level of $\approx 5$\% relative to the cosmic mean. However, whilst rare, the extent of these peculiarities does not significantly challenge the $Λ$CDM model. SIBELIUS-DARK is the most comprehensive constrained realisation simulation of the local volume to date, and with this paper we publicly release the halo and galaxy catalogues at $z=0$, which we hope will be useful to the wider astronomy community.

description: We present the first large-scale mosaic performed with the Submillimeter Array (SMA) in the Galactic center. We have produced a 25-pointing mosaic, covering a ~2' x 2' area around Sgr A*. We have detected emission from two high-density molecular tracers, HCN(4-3) and CS(7-6), the latter never before reported in this region. The data have an angular resolution of 4.6" x 3.1", and the spectral window coverage is from -180 km/s to 1490 km/s for HCN(4-3) and from -1605 km/s to 129 km/s for CS(7-6). Both molecular tracers present a very clumpy distribution along the circumnuclear disk (CND), and are detected with a high signal-to-noise ratio in the southern part of the CND, while they are weaker towards the northern part. Assuming that the clumps are as close to the Galactic center as their projected distances, they are still dense enough to be gravitationally stable against the tidal shear produced by the supermassive black hole. Therefore, the CND is a non-transient structure. This geometrical distribution of both tracers suggests that the southern part of the CND is denser than the northern part. Also, by comparing the HCN(4-3) results with HCN(1-0) results we can see that the northern and the southern parts of the CND have different excitation levels, with the southern part warmer than the northern. Finally, we compare our results with those obtained with the detection of NH3, which traces the warmer and less dense material detected in the inner cavity of the CND. We suggest that we are detecting the origin point where a portion of the CND becomes destabilized and approaches the dynamical center of the Milky Way, possibly being impacted by the southern streamer and heated on its way inwards.

description: In this paper, we study the quantum statistical entropy in a 5D Ricci-flat black string solution, which contains a 4D Schwarzschild-de Sitter black hole on the brane, by using the improved thin-layer method with the generalized uncertainty principle. The entropy is the linear sum of the areas of the event horizon and the cosmological horizon without any cut-off and any constraint on the bulk's configuration rather than the usual uncertainty principle. The system's density of state and free energy are convergent in the neighborhood of horizon. The small-mass approximation is determined by the asymptotic behavior of metric function near horizons. Meanwhile, we obtain the minimal length of the position $Δx$ which is restrained by the surface gravities and the thickness of layer near horizons.

Beyond the structural modelling for the analysis of organizational performances in the resilience management
Creators: name: Bianchi, Massimo
Publisher: name: Economia Aziendale Online
Year: 2019

description: The aim of this paper is to examine and discuss the perspectives in the analysis of organizational performances emerging from the theoretical and applied studies on resilience management. In the non-standard situations of emergency, characterized by extreme challenges and by the submission of organizational structures and processes to severe stresses, it derives a model, useful to evaluate organizational performances, inspired to the concept of arena once proposed by Mintzberg. The target is to detect the latent aspects of organizational performances opposed to the manifest ones, concepts at the basis of Merton’s functionalism in the study of social structures. Both Authors, coming from different historical periods and experiences, could give a fruitful contribution to the renewal of managerial theories, whose complexity is expressed in last times by the Interpretive Structural Modelling, with an approach founded on the simplification of the evaluation methodology. This could open a new perspective for the study of the gap between real and perceived performance. To this aim it was examined the application of this approach to three cases of International Projects in Balkan countries having the purpose of improving the resilience of High Educational Systems after the dissolution of previous regimes and consequent civil wars.

description: We investigate the effects of strong magnetic fields on the equation of state of dense stellar neutrino-free and neutrino-trapped matter. Relativistic nuclear models both with constant couplings (NLW) and with density dependent parameters (DDRH) and including hyperons are considered . It is shown that at low densities neutrinos are suppressed in the presence of the magnetic field. The magnetic field reduces the strangeness fraction of neutrino-free matter and increases the strangeness fraction of neutrino-trapped matter. The mass-radius relation of stars described by these equations of state are determined. The magnetic field makes the overall equation of state stiffer and the stronger the field the larger the mass of maximum mass star and the smaller the baryon density at the center of the star. As a consequence in the presence of strong magnetic fields the possibility that a protoneutron star evolves to a blackhole is smaller.

The roles of plasticity and adaptation in response to environmental change across temporal scales in fishes
Creators: name: Earhart, Madison
Publisher: name: University of British Columbia
Year: 2024

description: How organisms respond to environmental change is a fundamental question in biology, critical to our understanding of how animals will cope with climate change. Determining the climate change resilience of a species or population is a challenging task, as resilience can be influenced by phenotypic plasticity and genetic variation. Specifically in aquatic habitats, organisms encounter rapid environmental changes including variations in temperature, oxygen availability, and salinity which occur across different spatial and temporal scales. My thesis aimed to explore how plasticity and adaptation influence resilience to environmental change across these scales in three different fish species. The three species I studied were Atlantic killifish (Fundulus heteroclitus), white sturgeon (Acipenser transmontanus), and rainbow trout (Oncorhynchus mykiss). I measured whole-animal physiology and underlying molecular mechanisms to assess responses to climate change stressors across developmental stages and populations. In killifish and white sturgeon, I found that exposure to climate change stressors during development had lasting phenotypic effects and affected the plasticity of many traits. These studies underlined the importance of considering developmental stage when evaluating stressor effects, as individuals must persist despite environmental changes during sensitive life stages to survive. Also, in white sturgeon and killifish I demonstrated the impacts of simultaneous stressors on whole-animal performance and the underlying genetic mechanisms highlighting the detrimental impact of compounding stressors. To investigate the role genetic variation plays on the ability of fishes to cope with environmental change I assessed how adaptation to different environments can affect the stress response or survival in novel environments. I found that local adaptation can influence the magnitude and plasticity of the stress-axis in killifish, highlighting the potential for adaptive tradeoffs between the stress response, body condition, and survival in the wild. In rainbow trout, I found that adaptation to hatchery environments impacts offspring phenotypes and decreases survival in the wild, highlighting the interplay between adaptation and coping with novel stressors. My thesis contributes to our understanding of the basic biological question, “how do fishes cope with environmental change?”, and also provides evidence for concrete actions and conservation-management recommendations during climate change.

description: A type of overlapping grid in spherical coordinates called the Yin-Yang grid is successfully implemented into a 3D version of the explicit Eulerian grid-based code PROMETHEUS including self-gravity. The modified code successfully passed several standard hydrodynamic tests producing results which are in very good agreement with analytic solutions. Moreover, the solutions obtained with the Yin-Yang grid exhibit no peculiar behaviour at the boundary between the two grid patches. The code has also been successfully used to model astrophysically relevant situations, namely equilibrium polytropes, a Taylor-Sedov explosion, and Rayleigh-Taylor instabilities. According to our results, the usage of the Yin-Yang grid greatly enhances the suitability and efficiency of 3D explicit Eulerian codes based on spherical polar coordinates for astrophysical flows.

description: Neutron stars are a remarkable marriage of Einstein's theory of general relativity with nuclear physics. Their interiors harbor extreme matter that cannot be probed in the laboratory. At such high densities and pressures, their cores may consist predominantly of exotic matter such as free quarks or hyperons. Gravitational wave observations from the Laser Interferometer Gravitational-wave Observatory (LIGO) and from other interferometers, and X-ray observations from the Neutron Star Interior Composition Explorer (NICER), are beginning to pierce through the veil. These observations provide information about neutron star cores, and therefore, about the physics that makes such objects possible. In this review, we discuss what we have learned about the physics of neutron stars from gravitational wave and X-ray observations. We focus on what has been observed with certainty and what should be observable in the near future, with an eye out for the physics that these new observations will teach us.

description: We report extensive radial-velocity measurements of the two giant components of the detached, 104-day period binary system of Capella. Our highly accurate three-dimensional orbital solution based on all existing spectroscopic and astrometric observations including our own yields much improved masses of 2.466 +/- 0.018 M_Sun and 2.443 +/- 0.013 M_Sun for the primary and secondary (relative errors of 0.7% and 0.5%). Improved values are derived also for the radii (11.87 +/- 0.56 R_Sun and 8.75 +/- 0.32 R_Sun), effective temperatures (4920 +/- 70 K and 5680 +/- 70 K), and luminosities (79.5 +/- 4.8 L_Sun and 72.1 +/- 3.6 L_Sun). The distance is determined to be 13.042 +/- 0.028 pc. Capella is unique among evolved stars in that, in addition to all of the above, the chemical composition is known, including the overall metallicity [m/H], the carbon isotope ratio 12C/13C for the primary, and the lithium abundance and C/N ratios for both components. The latter three quantities are sensitive diagnostics of evolution, and change drastically for giants as a result of the deepening of the convective envelope during the first dredge-up. The secondary is crossing the Hertzprung gap, while the primary is believed to be in the longer-lived core-helium burning phase. However, we find that current stellar evolution models are unable to match all of the observations for both components at the same time, and at a single age, for any evolutionary state of the primary. Similar problems are found when testing the rotational synchronization, spin axis alignment, and orbital circularization of the system against tidal theory. We conclude that our understanding of the advanced stages of stellar evolution is still very incomplete. [Abridged]

Experimental investigation of the connection and system behavior of 3-panel BEHLEN Frameless panel under monotonic and cyclic loads
Creators: name: Feng, Baoli

description: Cold-formed steel corrugated panels have attracted increasing interest regarding seismic applications as lateral force-resisting systems. Engineered by BEHLEN Industries LP, BEHLEN Frameless systems represent a notable application of cold-formed steel, employing corrugated steel panels as their primary structural components. These systems offer a cost and energy efficient alternative to conventional low-rise, long-span steel structures. With limited data on their seismic resistance, a series of extensive experimental investigations was carried out at the University of British Columbia. Connection-level testing involved three common bolted connections employed in the BEHLEN Frameless systems: i) footing channel-to-foundation connection, ii) panel-to-column connection, and iii) panel-to-panel connection. A total of sixty specimens with different thicknesses of connected members, tightening torque applied, and material properties were tested in the connection testing program. A comprehensive evaluation of the bolted connections under monotonic and cyclic loadings on rigidity, ductility, force capacity, typical behavior, and failure mode was presented. Component-level testing involved two types of corrugated panels developed for the BEHLEN Frameless systems: i) CS45 corrugated panels and ii) CS75 corrugated panels. A total of eight three-panel specimens were tested under in-plane monotonic and cyclic loadings. A thorough investigation of the panel wall specimens was carried out by assessing the initial stiffness, the buckling load, the buckling drift ratios, the post-buckling stiffness, the buckling sequence and pattern, and the residual force capacity. Test results in the preceding phase were also reviewed and the effect of varying specimen thicknesses and aspect ratios was further examined. The findings from this thesis provided a robust foundation for building detailed finite element models for parametric study and analytical models for seismic performance assessment.
A marketing perspective on reshoring:  online corporate brand image and communication of reshored Italian companies

description: Building on a critical analysis of branding and reshoring literature, the present study theoretically and empirically contributes to extant knowledge, considering reshoring from a marketing perspective. The textual and semiotic analysis of the official corporate websites of 33 Italian companies – that reshored part of their activities to Europe – revealed that Italian companies still do not leverage on reshoring to form e refine the online corporate brand image. The present study has also a practical relevance for managers operating within the marketing business units, suggesting the relevance to communicate reshoring drivers – especially “Made in” effect and CSR policies that are the most relevant motivations of reshoring for Italian companies – to their audiences, leverage on reshoring to build brand image and to gain competitive advantage.

Measuring sub-Planck structural analogues in chronocyclic phase space

description: The phase space structure of certain quantum states reveals structure on a scale that is small compared to the Planck area. Using an analog between the wavefunction of a single photon and the electric field of a classical ultrashort optical pulse we show that spectral shearing interferometry enables measurement of such structures directly. Thereby extending the idea of Praxmeyer et al. In particular, we use multiple-shear spectral interferometry to fully characterize a pulse consisting of two sub-pulses which are temporally and spectrally disjoint, without a relative-phase ambiguity. This enables us to compute the Wigner distribution of the pulse. This spectrographic representation of the pulse field features fringes that are tilted with respect to both the time- and frequency axes, showing that in general the shortest sub-Planck distances may not be in the directions of the canonical (and easily experimentally accessible) directions. Further, independent of this orientation, evidence of the sub-Planck scale of the structure maybe extracted directly from the measured signal.

description: Resumen

Debido a la importancia en la seguridad ambiental, así como una respuesta a la pérdida de biodiversidad se crearon los bancos de germoplasma. Por ello, el Jardín Botánico Universitario de la Benemérita Universidad Autónoma de Puebla inició una colección con el apoyo de Botanic Gardens Conservation International. De acuerdo con un boletín de la universidad hasta 2021 la colección resguardaba 10 especies y más de 40 mil semillas [1].

Estos bancos son áreas o espacios donde se preserva material genético, mediante colecciones de semillas. Su objetivo es conservar la biodiversidad a largo plazo [2].

Su importancia reside en evitar la pérdida de la diversidad genética causada por diversos factores como lo son: ambientales, físicos, biológicos o por actos provocados por actividades antropogénicas. Dicha diversidad vegetal, sustenta el funcionamiento de ecosistemas y es uno de los principales soportes para la vida en nuestro planeta [3].

Para su posterior resguardo es importante llevar a cabo una caracterización morfológica ya que esto permite describir características cuantitativas y cualitativas de las semillas [4], dichas características ayudan a medir la variabilidad genética de una colección mediante el uso de descriptores definidos [5].

Después se llevan a cabo pruebas de viabilidad para las semillas, en el banco de germoplasma del JBU se llevan a cabo 3 pruebas fundamentales.

·         Prueba de flotación: Se fundamenta en el peso específico de cada semilla. Consiste en llenar un recipiente con etanol al 96% y dejar reposar las semillas durante 30 minutos. Las semillas vanas flotarán, mientras que las maduras y viables se hundirán [6].

·         Prueba de corte: Consiste en un corte longitudinal por la mitad de la semilla, con el fin de poder observar las condiciones del embrión. Si este presenta un color blanco o tonalidades color crema, la semilla es viable mientras que, si el color es amarillo intenso o café, la semilla es vana  [7].

·         Prueba de tetrazolio: Las semillas se mantienen en total oscuridad sumergidas por 24 horas en una solución de tetrazolio en concentraciones del 0.75%-1%. La prueba se fundamenta en una reacción de óxido-reducción por parte del indicador de tetrazolio con el propósito de indicar la respiración celular [8].

Al finalizar las pruebas, si el resultado es exitoso, se almacenan en el Laboratorio de Ecofisiología y Conservación donde pueden perdurar de 30 hasta 150 años en las condiciones adecuadas [1].
