Investigating the structure-function relationship of cationic antimicrobial peptides and lipopeptides
Creators: name: Cheng, John Tien Jui
Publisher: name: University of British Columbia
Year: 2010

description: Antibiotics have been playing a major role in combating bacterial infections for centuries. Since the discovery of modern antibiotics, numerous derivatives have been designed and developed to treat different bacterial infections. Recently, antibiotic resistance has been continuously and increasingly reported. The lack of antibiotic alternatives makes these resistant bacteria become more difficult to eliminate. Antimicrobial peptides constitute a major part of the innate immune system of an organism. Their high activity and little resistance make them ideal candidates for novel antibiotic development. This dissertation focuses on aurein peptides, a class of amphibian cationic antimicrobial peptides from Litoria aurea, and daptomycin, a lipopeptide. We have examined the structure-function relationship of two aurein peptides, aurein 2.2 and aurein 2.3. They were found to adopt alpha-helices and perturb membrane bilayers via mechanisms similar to toroidal pore or toroidal pore/liposome formation in model membranes. We have also designed and inspected the structure-activity correlation of different aurein 2.2 analogues by residue 13-substitutions and N- and/or C-terminal truncations. We have found that residue 13 and N-terminus are required for antimicrobial activity, whereas an N-terminal truncation gives rise to a peptide analogue with immunomodulatory activity in vitro. The effects of membrane composition and model membrane choice have been further investigated. We have found that the peptide behaviour is dependent on different model membranes. We have examined the importance of solvent accessibility in the mechanism of action for daptomycin and found that daptomycin molecules are indeed solvent-exposed in apo- and Ca2+-form and insert slightly into lipid membranes. Taken together, we have developed a set of references for future design of new antibiotics based on aurein peptides. By using this set of references as a starting point, we hope to gain a better understanding of how antimicrobial peptides function from structural and membrane perspectives and design novel antimicrobial agents to combat increasing antibiotic resistance in the future.

description: Non-aqueous redox flow batteries (NaRFBs) are a promising technology for widespread grid-scale energy storage deployment. Despite their potential for high energy density, current active materials lack the necessary stability and cyclability for scale-up. One class of active materials for NaRFBs are redox active organic molecules (ROMs), which are a focus of recent development due to their low cost and high solubilities compared to other candidate active materials. The research in this thesis seeks to advance of ROM development through characterization of new active materials and development of computational design tools for stability and cyclability. ROM characterization focused on cyclability of the dialkoxyarene ROM catholyte family and (2,2,6,6-Tetramethylpiperidin-1-yl)oxyl (TEMPO). An extensive set of bulk electrolysis (BE) experiments with varying active material concentration, cycle rate, and supporting salt were performed. Two different design strategies for improving dialkoxyarene cyclability were identified: increasing steric hinderance in alkylammonium electrolytes and increasing lithium-coordination in lithium electrolytes. These two strategies and the BE data provide new insight into ROM design and proper selection of electrolytes for cyclability. Computational work used the model building tool Sure Independence Screening and Sparsifying Operator (SISSO) to develop models for screening and prediction of ROMs. A variety of prediction tools for dialkoxyarene and TEMPO cyclability were developed, highlighting the lowest unoccupied molecular orbital (LUMO) energy and the solvation energy as the most important active material descriptors for improving cyclability. Similar tools were developed for dialkoxyarene stability, with the LUMO energy and geometry as the most important factors identified by SISSO. Most significantly, a generalized screening model for stability was developed from data for dialkoxyarene catholytes and pyridinium anolytes. This model is the first generalizable model for any ROM property of interest and provides insight into the unknown factors affecting electrochemical stability. These models provide foundations and methods for the computational design of new ROMs.
Mass analysis with quadrupoles with added multipole fields
Creators: name: Xiao, Zilan
Publisher: name: University of British Columbia
Year: 2010

description: Conventional mass analysis, mass analysis with islands of stability, and mass selective axial ejection were investigated using linear quadrupoles with added hexapole fields. Experiments agree with computer simulations. When the resolving dc is applied, so that the Mathieu parameter a>0, conventional mass analysis is possible. However, the transmission and resolution are low, and there is peak structure. When a<0, only very low resolution (80) and transmission are seen. With both a>0 and a<0, the use of islands of stability for mass analysis greatly improves peak shape, resolution, and in some cases, transmission. Mass selective axial ejection (MSAE), has also been investigated with linear quadrupoles with added hexapole fields. Trapped ions were ejected using dipole excitation with various ejection parameters: ejection q, excitation amplitude, excitation between the x or y rods, scan speed and scan direction. At high ejection q (q=0.73), excellent peak shapes and resolution up to 4500 were obtained. Scan speeds up to 4000 Th/s were possible. The optimal combination of specific rod set, scan direction, and dipole excitation rod pair was determined. MSAE at lower ejection q was also investigated and found to give lower resolution and spurious peaks on the low mass side of the peaks. Simulations were used to investigate mass analysis in islands of stability with linear quadrupoles with added octopole or hexapole fields. With both a>0 and a<0, the best resolution and peak shape are obtained with operation at the upper tip of the uppermost island formed with the auxiliary excitation. The improvement of resolution and peak shape with a<0, confirms that the use of islands generally can provide a method for mass analysis when added multipole fields otherwise prevent mass analysis. The possibility of operating conventional quadrupole as a mass filter and ion trap as Q3 in a triple quadrupole system is limited because of its low fragmentation efficiency at low pressure. Quadrupoles with added multipoles give greater fragmentation efficiency at 1x10⁻⁴ Torr. The experiments and simulations here suggest that quadrupoles with added hexapole fields might be good candidates where Q3 must be operated as both a trap and mass filter.

description: With a rapidly growing functionality of embedded real-time applications, it becomes inevitable to integrate tasks of different safety integrity levels on one many-core processor leading to a large-scale mixed-criticality system. In this process, it is not sufficient to only isolate shared architectural resources, as different tasks executing on different cores also possibly interfere via the many-core processor’s thermal management. This can possibly lead to best-effort tasks causing deadline violations for safety-critical tasks. In order to prevent such a scenario, we propose a monitoring-based hardware extension that communicates imminent thermal violations between cores via a lightweight interconnect. Building on this infrastructure, we propose a thermal strategy such that best-effort tasks can be throttled in favor of safety-critical tasks. Furthermore, assigning static voltage/frequency (V/f) levels to each safety-critical task based on their worst-case execution time may result in unnecessary high V/f levels when the actual execution finishes faster. To free the otherwise wasted thermal resources, our solution monitors the progress of safety-critical tasks to detect slack and safely reduce their V/f levels. This increases the thermal headroom for best-effort tasks, boosting their performance. In our evaluation, we demonstrate our approach on an 80-core processor to show that it satisfies the thermal and deadline requirements, and simultaneously reduces the run-time of best-effort tasks by up to 45% compared to the state of the art.

description: Vaccination is one of the most successful public health interventions in modern medicine. However, it is still challenging to develop effective vaccines against many infectious diseases such as tuberculosis, HIV, and malaria. There are challenges in integrating the high volume, variety, and variability of vaccine-related data and rationally designing effective and safe vaccines efficiently. In my thesis study, I systematically and comprehensively analyzed manually annotated protective vaccine antigens in the Protegen database and identified these protective antigens' enriched patterns. I then created Vaxign-ML, a novel machine learning-based reverse vaccinology method based on the curated Protegen data for rational vaccine design. Vaxign-ML was used to successfully predict vaccine antigens for tuberculosis and Coronavirus Disease 2019 (COVID-19). I also developed a new structural vaccinology design program that optimizes COVID-19 spike glycoprotein as a vaccine candidate for enhanced vaccine protection via T cell epitope engineering. The vaccine antigens selected and optimized by Reverse and Structural Vaccinology in this dissertation are subjected to future experimental verification. Furthermore, I created a community-based Ontology of Host-Pathogen Interactions (OHPI), which served as a platform to semantically represent the interactions between host and virulence factors that are also protective antigens. I developed the Vaccine Investigation Ontology (VIO) for standardized metadata representation for high throughput vaccine OMICS data analysis. Overall, my thesis research aims to uncover protective antigen patterns, create methods/tools to effectively develop vaccines against infectious diseases of public health significance, and strengthen our understanding of vaccine protection mechanisms. These works can be further expanded and integrated with other technologies such as epitope prediction, molecular epidemiology, and high-throughput sequencing to build the foundation of precision vaccinology.

description: Fascism, Populism and Common Sense in Spain: La Gaceta Literaria, La Conquista del Estado, F.E. y Vértice (1927-1939) focuses on the emergence of Spanish fascism in a crucial period of Spain's history: the end of the monarchy, the proclamation of the Second Republic, the outbreak of the Civil War, and the establishment of Franco’s dictatorship. Drawing on theories about populism and common sense, this work demonstrates the changing and contingent fascist propagandas of the magazines cited in the title in order to appeal to the popular discourses shared by a variety of non- fascist ideologies and organizations. This dissertation poses questions that resonate in today’s controversial situation with the ascendance of extremist populisms and the never- ending presence of the word "fascism" as a rhetorical tool against the opponent in the political debate.
title: A statistical examination of British bird observatories data

Publisher: name: University of Kent

description: British bird observatories data are examined from a statistical viewpoint. Consideration is given to the forming of indices of migration volume which can be used to monitor fluctuations in breeding population levels. The collection of daily counts of grounded migrants is discussed and simple graphical techniques are used to explore migratory behaviour of some common nocturnal migrants. The timing of migration is found to be related to population size as measured by the Common Bird Census. Statistical models are fitted to sequences of daily counts of grounded migrants but migration indices developed from these models are shown to offer no significant improvements over those based on the timing of migration. Linear discriminant analysis is shown to be a useful method of linking weather data with observatories data, and statistical models are developed for daily counts which utilise weather information.

Orbital Eccentricity Distribution of Solar-Neighbour Halo Stars

Year: 2011
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present theoretical calculations for the differential distribution of stellar orbital eccentricity for a sample of solar-neighbour halo stars. Two types of static, spherical gravitational potentials are adopted to define the eccentricity e for given energy E and angular momentum L, such as an isochrone potential and a Navarro-Frenk-White potential that can serve as two extreme ends covering in-between any realistic potential of the Milky Way halo. The solar-neighbour eccentricity distribution ΔN(e) is then formulated, based on a static distribution function of the form f(E,L) in which the velocity anisotropy parameter βmonotonically increases in the radial direction away from the galaxy center, such that beta is below unity (near isotropic velocity dispersion) in the central region and asymptotically approaches \sim 1 (radially anisotropic velocity dispersion) in the far distant region of the halo. We find that ΔN(e) sensitively depends upon the radial profile of β, and this sensitivity is used to constrain such profile in comparison with some observational properties of ΔN_{obs}(e) recently reported by Carollo et al. (2010). Especially, the linear e-distribution and the fraction of higher-e stars for their sample of solar-neighbour inner-halo stars rule out a constant profile of β, contrary to the opposite claim by Bond et al. (2010). Our constraint of β\lesssim 0.5 at the galaxy center indicates that the violent relaxation that has acted on the inner halo is effective within a scale radius of \sim 10 kpc from the galaxy center. We discuss that our result would help understand the formation and evolution of the Milky Way halo.

description: Automation of an industrial OPC UA FX use case through the usage of proactive Asset Administration Shells Katharina Justmann1, Ludwig Leurs2, Jesko Hermann3, Martin Ruskowski4 Abstract: Flexible and order-driven production are essential concepts for smart factories that effectively carry out lot-size-one production. These concepts depend on manufacturer-independent information exchange throughout the production lifecycle. While Open Platform Communication Unified Architecture Field eXchange (OPC UA FX) enables standardized communication between shop floor controllers, its configuration requires additional effort. To achieve flexible communication in changing production environments the configuration needs to be automated. The Asset Administration Shell (AAS) and the associated bidding process offer a potential solution to achieve this automation. The concept of a combination of the AAS and OPC UA FX was already formulated [DWR22a]. In this paper this concept is extended with activities of the Capability, Skill, and Service model to automate the configuration and production planning process of an OPC UA FX demonstrator. This paper shows that the information models and concepts are complementary yet lack generic mappings between the defined structures and semantics.
Investigation of atmospheric phase transitions in low temperature, mixed aerosols
Creators: name: Bodsworth, Aidan Neville Fredrick
Publisher: name: University of British Columbia
Year: 2011

description: Atmospheric aerosols are very small liquid or solid droplets which are suspended in a gas. They are present in our atmosphere in great numbers (10³ particles per cm³ in unpolluted rural environments). They represent a substantial source of uncertainty in climate models and influence human health, atmospheric reactivity and visibility. Field studies have shown that mixed organic-inorganic aerosols are abundant in the atmosphere. Mixed aerosols undergo phase transitions between aqueous and crystalline phases, called efflorescence and deliquescence. By examining laboratory prepared mixed droplets in a temperature and humidity controlled flow cell, these phase transitions were observed optically. We studied the efflorescence properties of mixed citric acid-ammonium sulfate particles as a function of temperature to better understand the efflorescence properties of mixed organic-inorganic particles in the middle and upper troposphere. Data at 293 K illustrates that the addition of citric acid decreases the efflorescence relative humidity (ERH) of ammonium sulfate, which is consistent with the trends observed with other systems containing highly oxygenated organic compounds. At low temperatures the trend is qualitatively the same, but efflorescence can be inhibited by smaller concentrations of citric acid. For example at temperatures < 250 K an organic/(organic+sulfate) mass ratio of only 0.333 is needed to inhibit efflorescence of ammonium sulfate. In the upper troposphere the organic/(organic+sulfate) mass ratio can often be larger than this value. We also studied phase transitions in ammonium sulfate-3-hydroxy-4-methoxy-mandelic acid (HMMA) systems. These systems showed similar trends in deliquescence and efflorescence to the citric acid case, but also underwent phase separations at an RH of approximately 77%. Again, low temperatures inhibited phase transitions. It is believed that the inhibition of efflorescence and phase separation stems from either an increase in viscosity or the formation of an organic glass, this is investigated using classical nucleation theory and DSC measurements. These studies imply that particles in the upper troposphere may be less likely to form or remain in the crystalline state than previously thought and that solid ammonium sulfate may be less likely to participate in heterogeneous ice nucleation in the upper troposphere. Additional studies are required on other model organic systems.

description: A spatial stochastic model is developed which describes the 3D nanomorphology of composite materials, being blends of two different (organic and inorganic) solid phases. Such materials are used, for example, in photoactive layers of hybrid polymer zinc oxide solar cells. The model is based on ideas from stochastic geometry and spatial statistics. Its parameters are fitted to image data gained by electron tomography (ET), where adaptive thresholding and stochastic segmentation have been used to represent morphological features of the considered ET data by unions of overlapping spheres. Their midpoints are modeled by a stack of 2D point processes with a suitably chosen correlation structure, whereas a moving-average procedure is used to add the radii of spheres. The model is validated by comparing physically relevant characteristics of real and simulated data, like the efficiency of exciton quenching, which is important for the generation of charges and their transport toward the electrodes.

description: Nomenclatural and taxonomic information are crucial for curating botanical collections. In the course of changing methods for systematic and taxonomic studies, classification systems changed considerably over time (Dalla Torre and Harms 1900, Durand and Bentham 1888, Endlicher 1836, Angiosperm Phylogeny Group et al. 2016). Various approaches to store preserved material have been implemented, most of them based on scientific names (e.g., families, genera, species) often in combination with other criteria such as geographic provenance or collectors. The collection management system, JACQ, was established in the early 2000s then developed to support multiple institutions. It features a centralised data storage (with mirror sites) and access via the Internet. Participating collections can download their data at any time in a comma-separated values (CSV) format. From the beginning, JACQ was conceived as a collaboration platform for objects housed in botanical collections, i.e., plant, fungal and algal groups. For these groups, various sources of taxonomic reference exist, nowadays online resources are preferred, e.g., Catalogue of Life, AlgaeBase, Index Fungorum, Mycobank, Tropicos, Plants of the World Online, International Plant Names Index (IPNI), World Flora Online, Euro+Med, Anthos, Flora of Northamerica, REFLORA, Flora of China, Flora of Cuba, Australian Virtual Herbarium (AVH).

description: Purpose: Female urologists are distinctly underrepresented in leading positions. The reasons behind this inequity remain unclear, with some suggesting factors such as family responsibilities, part-time work and insufficient mentorship. This study aimed to explore and characterize the working conditions of female urologists in Germany, with a focus on factors influencing the working time model. Methods: A questionnaire was developed and distributed to 1343 female members of the German Society of Urology between February and March 2022. The survey consisted of 43 questions covering the categories demographics, occupation situation, satisfaction at work, family situation, career aspects and research activity. Results: Of the 487 female German urologists who participated in the survey, 167 (34.3%) worked part-time. Doctors in training were significantly less likely to work part-time than colleagues who had completed their specialist training (p < 0.001). Only 10% of female doctors in training reported working part-time. Similarly, having children (p < 0.001) and engaging in scientific activities (p = 0.03) were independent factors influencing part-time work, with children increasing the likelihood of working part-time as expected, while scientifically active female urologists were more likely to work full-time. Conclusion: This study provides the largest survey on the situation of female urologists in German-speaking countries to date. Part-time work during specialist training is rare, while more than 50% of female urologists with children work part-time. With the projected decline in the number of practicing physicians and the increasing demand for medical attention, it is crucial to find ways to retain and support healthcare professionals, particularly female urologists.

description: Introduction: Immunocompromised patients are at increased risk for herpes zoster (HZ)-associated complications. Despite standard therapy with systemic antiviral drugs and analgesics, complications are frequently encountered, including generalization of lesions or persistent neuropathic pain, so-called post-herpetic neuralgia (PHN). Given the scarcity of literature and awareness of therapeutic options to improve patient outcomes, especially for vulnerable patient groups, here we describe a strategy based on early intensification of treatment with a varicella zoster virus-specific hyperimmunoglobulin (VZV-IgG), which is approved in the adjuvant treatment of HZ. Methods: For this case series, we selected four cases of HZ in patients with impaired immunity due to hemato-oncologic disease or immunosuppressive treatment who presented with either existing generalized lesions and/or severe pain or with other risk factors for a complicated HZ course such as PHN. They were considered to be representative examples of different patient profiles eligible for intensification of treatment by the addition of VZV-IgG to virostatic therapy. Case Report: All patients showed a rapid response to combined treatment with VZV-IgG and a virostatic agent. In two patients who had generalized lesions, the formation of new lesions ceased 1 day after VZV-IgG infusion. One patient, with mantle cell lymphoma, achieved complete healing of the lesions 9 days after diagnosis of HZ, a rare occurrence compared to similar cases or cohorts. A patient with HZ in the cervical region showed a good response after a single dose of VZV-IgG. None of the patients developed post-zoster-related complications. Combination therapy of a virostatic agent and VZV-IgG was well tolerated in these four cases. Conclusion: This case series demonstrates highly satisfactory treatment effectiveness and tolerability for VZV-IgG in the adjuvant treatment of immunocompromised HZ patients and supports early intensification of HZ therapy in patients at high risk of severe disease progression.

description: We consider the quasi-linear eigenvalue problem $-Δ_p u = λg(u)$ subject to Dirichlet boundary conditions on a bounded open set $Ω$, where $g$ is a locally Lipschitz continuous functions. Imposing no further conditions on $Ω$ or $g$ we show that for small $λ$ the problem has a bounded solution which is unique in the class of all small solutions. Moreover, this curve of solutions depends continuously on $λ$.

description: Calcineurin, a serine/threonine phosphatase regulating transcription factors like NFaT and CREB, is well known for its immune modulatory effects and role in cardiac hypertrophy. Results from experiments with calcineurin knockout animals and calcineurin inhibitors indicate that calcineurin also plays a crucial role in vascular function, especially in vascular smooth muscle cells (VSMCs). In the aorta, calcineurin stimulates the proliferation and migration of VSMCs in response to vascular injury or angiotensin II administration, leading to pathological vessel wall thickening. In the heart, calcineurin mediates coronary artery formation and VSMC differentiation, which are crucial for proper heart development. In pulmonary VSMCs, calcineurin/NFaT signaling regulates the release of Ca2+, resulting in increased vascular tone followed by pulmonary arterial hypertension. In renal VSMCs, calcineurin regulates extracellular matrix secretion promoting fibrosis development. In the mesenteric and cerebral arteries, calcineurin mediates a phenotypic switch of VSMCs leading to altered cell function. Gaining deeper insights into the underlying mechanisms of calcineurin signaling will help researchers to understand developmental and pathogenetical aspects of the vasculature. In this review, we provide an overview of the physiological function and pathophysiology of calcineurin in the vascular system with a focus on vascular smooth muscle cells in different organs. Overall, there are indications that under certain pathological settings reduced calcineurin activity seems to be beneficial for cardiovascular health.

description: In this paper a method is proposed for performance evaluation of road traffic control systems. The method is designed to be implemented in an on-line simulation environment, which enables optimisation of adaptive traffic control strategies. Performance measures are computed using a fuzzy cellular traffic model, formulated as a hybrid system combining cellular automata and fuzzy calculus. Experimental results show that the introduced method allows the performance to be evaluated using imprecise traffic measurements. Moreover, the fuzzy definitions of performance measures are convenient for uncertainty determination in traffic control decisions.

description: We present a spectroscopic survey of 21 young massive clusters and complexes and one tidal dwarf galaxy candidate (TDG) in Stephan's Quintet, an interacting compact group of galaxies. All of the selected targets lie outside the main galaxies of the system and are associated with tidal debris. We find clusters with ages between a few and 125 Myr and confirm the ages estimated through HST photometry by Fedotov et al. (2011), as well as their modelled interaction history of the Quintet. Many of the clusters are found to be relatively long-lived, given their spectrosopically derived ages, while their high masses suggest that they will likely evolve to eventually become intergalactic clusters. One cluster, T118, is particularly interesting, given its age (\sim 125 Myr), high mass (\sim 2\times10^6 M\odot) and position in the extreme outer end of the young tidal tail. This cluster appears to be quite extended (Reff \sim 12 - 15 pc) compared to clusters observed in galaxy disks (Reff \sim 3 - 4 pc), which confirms an effect we previously found in the tidal tails of NGC 3256, where clusters are similarly extended. We find that star and cluster formation can proceed at a continuous pace for at least \sim 150 Myr within the tidal debris of interacting galaxies. The spectrum of the TDG candidate is dominated by a young population (\sim 7 Myr), and assuming a single age for the entire region, has a mass of at least 10^6 M\odot.

description: Absolute {\it K}-shell photoionization cross sections for atomic nitrogen have been obtained from both experiment and state-of-the-art theoretical techniques. Due to the difficulty of creating a target of neutral atomic nitrogen, no high-resolution {\it K}-edge spectroscopy measurements have been reported for this important atom. Interplay between theory and experiment enabled identification and characterization of the strong $1s$ $\rightarrow$ $np$ resonance features throughout the threshold region. An experimental value of 409.64 $\pm$ 0.02 eV was determined for the {\it K}-shell binding energy.

description: We develop the metric theory of Diophantine approximation on homogeneous varieties of semisimple algebraic groups and prove results analogous to the classical Khinchin and Jarnik theorems. In full generality our results establish simultaneous Diophantine approximation with respect to several completions, and Diophantine approximation over general number fields using S-algebraic integers. In several important examples, the metric results we obtain are optimal. The proof uses quantitative equidistribution properties of suitable averaging operators, which are derived from spectral bounds in automorphic representations.

description: Bees are the most important pollinators and, like many other insects, are facing a global decline that threatens crop pollination services. Both honey bees and some wild bee species are used commercially for pollination, including pollination in blueberry and cherry orchards. In our study, we assessed bee visits to experimental blueberry and cherry orchards immersed in an urban landscape to understand how air-temperature affects the potential contribution of honey bees and wild bees to pollination services. The potential contribution to pollination services was estimated using the Pollination Importance Value index, where the pollen collected by the floral visitor is a determining variable. In our study, bumble bees and honey bees were the most important floral visitors in the orchards, followed by the wild bee Anthophora plumipes. We found that honey bees were affected by changes in air-temperature and their decrease in the potential contribution to pollination services was offset by the niche complementarity provided by bumble bees. Implications for insect conservation Even small changes in air-temperature can alter bee communities by affecting bee species susceptible to low temperatures. Our work is a first assessment of how climate change may affect the complementarity of pollinator communities in orchards. We suggest that strategies to mitigate local air-temperature changes in urban areas, focusing primarily on these species, could potentially have cascading effects that would support the overall pollination services provided by bee communities.

description: Gas-phase NMR spectra demonstrating the effect of weak intermolecular forces on the NMR shielding constants of the interacting species are reported. We analyse the interaction of the molecular hydrogen isotopomers with He, Ne, and Ar, and the interaction in the He-CO_2 dimer. The same effects are studied for all these systems in the ab initio calculations. The comparison of the experimental and computed shielding constants is shown to depend strongly on the treatment of the bulk susceptibility effects, which determine in practice the pressure dependence of the experimental values. Best agreement of the results is obtained when the bulk susceptibility correction in rare gas solvents is evaluated from the analysis of the He-rare gas interactions, and when the shielding of deuterium in D_2-rare gas systems is considered.
