description: Double blind $T$-private information retrieval (DB-TPIR) enables two users, each of whom specifies an index ($θ_1, θ_2$, resp.), to efficiently retrieve a message $W(θ_1,θ_2)$ labeled by the two indices, from a set of $N$ servers that store all messages $W(k_1,k_2), k_1\in\{1,2,\cdots,K_1\}, k_2\in\{1,2,\cdots,K_2\}$, such that the two users' indices are kept private from any set of up to $T_1,T_2$ colluding servers, respectively, as well as from each other. A DB-TPIR scheme based on cross-subspace alignment is proposed in this paper, and shown to be capacity-achieving in the asymptotic setting of large number of messages and bounded latency. The scheme is then extended to $M$-way blind $X$-secure $T$-private information retrieval (MB-XS-TPIR) with multiple ($M$) indices, each belonging to a different user, arbitrary privacy levels for each index ($T_1, T_2,\cdots, T_M$), and arbitrary level of security ($X$) of data storage, so that the message $W(θ_1,θ_2,\cdots, θ_M)$ can be efficiently retrieved while the stored data is held secure against collusion among up to $X$ colluding servers, the $m^{th}$ user's index is private against collusion among up to $T_m$ servers, and each user's index $θ_m$ is private from all other users. The general scheme relies on a tensor-product based extension of cross-subspace alignment and retrieves $1-(X+T_1+\cdots+T_M)/N$ bits of desired message per bit of download.

Insights into the catalytic mechanism of a retaining xylanase from Cellulomonas fimi
Creators: name: Wicki, Jacqueline
Publisher: name: University of British Columbia
Year: 2011

description: The family 10 xylanase from Cellulomonas fimi (Cex) is an important model enzyme on which numerous mechanistic studies have been performed. This enzyme catalyzes the hydrolysis of β-glycosidic linkages via a double-displacement mechanism involving the formation and subsequent breakdown of a covalent glycosyl-enzyme intermediate with net retention of stereochemistry at the centre undergoing substitution. The finer details of the mechanism of this enzyme were investigated in three studies in order to gain a better understanding of this family of enzymes. In the first study presented in Chapter 2, the roles of key active-site residues in the catalytic mechanism of Cex were investigated by utilizing site-directed mutagenesis in combination with steady state kinetic analyses and pH-rate dependencies. The rate-determining step for the aryl substrates tested remains deglycosylation for many of the enzymes, while the altered pH profiles demonstrate a role for these highly conserved residues in the hydrogen-bond network responsible for maintaining the ionization state of the two catalytic residues. In Chapter 3, a second study addresses a fundamental enquiry of mechanistic enzymology; that is, how distal and proximal substrate interactions influence catalysis. By systematically removing hydrogen-bonding interactions through modification, individually, of substrate and enzyme, deep insight is gained into the effects of these modifications on each step of the hydrolysis reaction catalyzed by Cex and a family 11 xylanase (Bcx). The data obtained provide significant insight into the contributions of hydrogen-bonding interactions at the distal and proximal sites. The strongest bond energies were measured in the proximal site, suggesting that these interactions are critical for substrate binding and bond hydrolysis. A particularly important finding of this study is that both 'uniform' and 'differential' binding interactions are recruited in the active site of a single enzyme. The third study, presented in Chapter 4, examines how well a series of five high affinity inhibitors mimic the transition state of Cex as a function of the sp²- or sp³ -hybridization state of the "anomeric carbon". Kinetic parameters for o-nitrophenyl β-xylobioside were determined, and very good correlations were observed in logarithmic plots relating the K[sub i] value for the sp² -hybridized class of inhibitor with 10 mutants and k[sub cat]/K[sub m] for the hydrolysis of the substrate by the corresponding mutants. The dependence was significantly less in the plot of log(and k[sub cat]/K[sub m]) versus log(1/K[sub i]) for the sp³-hybridized class of inhibitor, indicating that the sp²-hybridized class of inhibitors more closely mimics the geometry of the transition state than does the sp³-hybridized class of inhibitors.

description: We report the discovery of a new, non-eclipsing SU UMa-type dwarf nova, HS 2219+1824. Photometry obtained in quiescence (V ~ 17.5) reveals a double-humped light curve from which we derive an orbital period of ~ 86.2 min. Additional photometry obtained during a superoutburst reaching V ~ 12.0 clearly shows superhumps with a period of ~ 89.05 min. The optical spectrum contains double-peaked Balmer and HeI emission lines from the accretion disc as well as broad absorption troughs of Hbeta, Hgamma, and Hdelta from the white dwarf primary star. Modelling of the optical spectrum implies a white dwarf temperature of 13000 K

description: The large mechanical luminosity of the jets of GRS 1915+105 should give rise to luminous emission regions, similar to those observed in radio galaxies, where the jets interact with the gas surrounding the source. However, no radio synchrotron emission of the expected morphology has been found. Here we present the results of a study suggesting that radio bremsstrahlung from the compressed and heated ISM in front of the jets should be detectable, while the synchrotron lobes may be too faint. We identify these jet impact sites with two well-known IRAS regions. This identification suggests a distance of GRS 1915+105 of $6.5\pm1.6$ kpc, significantly closer than the usually assumed distance of 11 to 12 kpc. We discuss the implications of this reduced distance estimate. The apparent motion of small-scale jet components is not superluminal, so if superluminal motion is required for an object to be termed a microquasar, GRS 1915+105 actually does not qualify. The mass of the black hole in the system is increased to $21\pm9$ M$_{\odot}$ while the mechanical luminosity of the jets is reduced to 14% of the Eddington luminosity.

description: A survey of 76 public smallholder irrigation schemes in the Limpopo Province was jointly conducted by the International Water Management Institute (IWMI), Department of Agriculture, Forestry and Fisheries (DAFF), South Africa, and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the ‘Revitalization of Smallholder Irrigation in South Africa’ project. About one-third of those schemes was fully utilized; one-third partially utilized; and one-third not utilized in the winter of 2015; however, no single socioeconomic, physical, agronomic and marketing variable could explain these differences in utilization. Sale, mostly for informal markets, appeared the most important goal. Dilapidated infrastructure was the most important constraint cited by the farmers. The study recommends ways to overcome the build-neglect-rebuild syndrome, and to learn lessons from informal irrigation, which covers an area three to four times as large as public irrigation schemes in the province.

description: We study the $CP$ asymmetry of $B^\pm\to ωK^\pm$ with the inclusion of the $ρ-ω$ mixing mechanism. It is shown that the $CP$ asymmetry of $B^\pm\toωK^\pm$ experimentally measured ($A_{CP}^{\text{exp}}$) and conventionally defined ($A_{CP}^{\text{con}}$) are in fact different, which relation can be illustrated as $A_{CP}^{\text{exp}}=A_{CP}^{\text{con}}+ΔA_{CP}^{ρω}$, with $ΔA_{CP}^{ρω}$ the $ρ-ω$ mixing contribution to $A_{CP}^{\text{exp}}$. $A_{CP}^{\text{exp}}$ is in fact the regional $CP$ asymmetry of $B^\pm\toπ^+π^-π^0 K^\pm$ when the invariant mass of the three pions lies in the vicinity of the $ω$ resonance. The numerical value of $ΔA_{CP}^{ρω}$ is extracted from the experimental data of $B^\pm\toπ^+π^-K^\pm$ and is found to be comparable with $A_{CP}^{\text{exp}}$, hence, nonnegligible. The conventionally defined $CP$ asymmetry, $A_{CP}^{\text{con}}$, is obtained from the values of $A_{CP}^{\text{exp}}$ and $ΔA_{CP}^{ρω}$, and is compared with the theoretical calculations in the literature.

description: We show that scalar as well as vector and tensor metric perturbations in the Randall-Sundrum II braneworld allow normalizable tachyonic modes, i.e., possible instabilities. These instabilities require nonvanishing initial anisotropic stresses on the brane. We show with a specific example that within the Randall-Sundrum II model, even though the tachyonic modes are excited, no instability develops. We argue, however, that in the cosmological context instabilities might in principle be present. We conjecture that the tachyonic modes are due to the singularity of the orbifold construction. We illustrate this with a simple but explicit toy model.

title: Subglacial rhyolite volcanism at Torfajökull, Iceland
Creators: name: Tuffen, Hugh
Publisher: name: The Open University
Year: 2002

description: Subglacial rhyolite eruptions at Torfajökull, Iceland have produced a variety of volcanic edifices during the last glacial period (115-11 ka). These range from small-volume (<0.1 km3) volcanoes, such as Bláhnúkur and Dalakvíslfell, to larger volume (~1 km3) flat-topped tuyas such as South-east Rauđufossafjöll. Lithofacies associations at each volcano record distinct phases of volcano-ice interaction beneath temperate glaciers at least 350 m thick.

All eruptions began with the construction of a pile of glassy fragmental material within a subglacial cavity. Fragmentation at Bláhnúkur was primarily caused by quenching, when rising magma encountered meltwater. Fragmentation at Southeast Rauđufossafjöll was apparently more energetic, and generated phreatomagmatic ash over 300 m thick. Dalakvíslfell is intermediate between the other two localities. Most fragmental deposits are massive, suggesting that a sustained meltwater lake did not develop during eruptions, in contrast with evidence from many basaltic volcanoes. Instead, meltwater drained away in a number of discrete channels, some of which have been identified. The eruption at Bláhnúkur apparently terminated before the glacier surface had been pierced, whereas the eruption at South-east Rauđufossafjölll produced a cap of flat-lying subaerial lava flows about 1.5 km in length.

Numerical models are presented, in which simple patterns of ice melting and deformation are used to simulate the evolving size of subglacial cavities during eruptions. The radius of the cavity is compared to the radius of the growing subglacial volcano. The models predict that, at low magma discharge rates and beneath thick ice, cavities will become completely filled with volcanic debris and the eruption will be dominantly intrusive, forming the types of lithologies observed at Bláhnúkur. Cavities never become filled at higher magma discharge rates, and an explosive phreatomagmatic eruption is predicted, which would form the types of lithologies observed at South-east Rauđufossafjöll.
Possible non-decoupling effects of heavy Higgs bosons in e+ e- -> W+ W- within THDM

description: We discuss the origin of the nondecoupling effects of the heavy Higgs bosons within the two Higgs doublet extension (THDM) of the Standard Model (SM) and illustrate it by means of the one-loop calculation of the differential cross-sections of the process e+ e- -> W+ W- in both the decoupling and the non-decoupling regimes. We argue that there are many regions in the THDM parametric space in which the THDM and SM predictions differ by several percents and such effects could, at least in principle, be testable at the future experimental facilities.

Efficient numerical techniques for predicting process-induced stresses and deformations in composite structures
Creators: name: Arafath, Abdul Rahim Ahamed
Publisher: name: University of British Columbia
Year: 2011

description: During the last two decades of research work in numerical modelling of autoclave processing of composite structures, several models have been developed ranging from simple one-dimensional elastic to sophisticated three dimensional viscoelastic models. Some of the common problems faced by these numerical models are the non-familiarity of general users with these models, their non-versatility, their inefficiency when running large problems and the interpretation and validation of the results produced by these models. The main objective of this research work is to initiate the development of the next generation process model for autoclave processing of composite structures to address the above problems. This development is carried out by building on the already established knowledge of process modelling within the UBC Composites Group. The developed next generation process model consists of a set of numerical tools which range in complexity from a simple and robust closed-form analytical tool to a more general and adaptive shell-based finite element analysis tool that provides a modeller with a choice depending on the time and cost constraints. According to the developed closed-form solution, the axial stress variation in the thickness direction of a flat composite part varies exponentially with the through-thickness coordinate and its gradient depends on the part material and geometrical properties. It is shown that the process-induced unbalanced moment develops mainly at the initial stages of the curing process where the through-thickness stress gradient is significant. The process-induced effects in a curved part due to the thermal strain mismatch between the part and the tool in the tangential direction is similar to the process-induced effects in a flat part. Apart from the tangential thermal strain mismatch, the radial thermal strain mismatch between the part and the tool also induces stresses in a curved part. These stresses are due to the radial and tangential constraints applied by the tool on the part to conform the part to the tool shape. The unbalanced moment due to these stresses mostly develop at the cool-down portion of the cure cycle when the material is fully cured.

description: Developing breadfruit reach maturity some 15-20 weeks after the female inflorescence is first detectable on the tree. The first half of this developmental period is characterised by size increase while the latter phase involves the laying down of starch reserves and increases in dry weight. The respiratory climacteric of harvested breadfruit parallels the softening of the fruit and peaks at 200 ml CO2 kg-I h- 1. Peak ethylene production is lower ( 1.5 μl C2H4 kg-I h- 1 ) than would be anticipated from such high respiratory rates, nonetheless, fruit are highly sensitive to ethylene. Attempts at Modified Atmosphere Storage using a wide range of coatings and plastic films have shown that breadfruit can be successfully stored at ambient for up to 3 weeks in polyethylene bags without ill effects. Such successful treatments were characterised by CO2 levels of about 10% (v/v) and 0 2 levels of 5-8 % (v/v) in the bags.

description: Tantalum nitride thin films have been grown by in situ nitrogen implantation of metallic tantalum at room temperature over the energy range of 0.5-5keV. X-ray photoelectron spectroscopy (XPS) and Factor Analysis (FA) have been used to characterise the chemical composition of the films. The number of the different Ta-N phases formed during nitrogen implantation, as well as their spectral shape and concentrations, have been obtained using principal component analysis (PCA) and iterative target transformation factor analysis (ITTFA), without any prior assumptions. According to FA results, the composition of the tantalum nitride films depends on both the ion dose and ion energy, and is mainly formed by a mixture of metallic tantalum, beta-TaN0.05, gamma-Ta2N and cubic/hexagonal TaN phases.

description: In the context of complex systems and, particularly, of protein folding, a physically meaningful distance is defined which allows to make useful statistical statements about the way in which energy differences are modified when two different instances of the same potential-energy function are used. When the two instances arise from the fact that different algorithms or different approximations are used, the distance herein defined may be used to evaluate the relative accuracy of the two methods. When the difference is due to a change in the free parameters of which the potential depends on, the distance can be used to quantify, in each region of parameter space, the robustness of the modeling to such a change and this, in turn, may be used to assess the significance of a parameters' fit. Both cases are illustrated with a practical example: the study of the Poisson-based solvation energy in the Trp-Cage protein (PDB code 1L2Y).

description: Die jüdische Migration aus der Sowjetunion nach dem Zweiten Weltkrieg (und auch nach deren Auflösung) ist eine der größten in der modernen Geschichte. Insgesamt 2,75 Millionen sowjetische Juden verließen die UdSSR in Richtung Israel, Vereinigte Staaten, Deutschland und anderswo. Die Haltung des sowjetischen Staates gegenüber der Auswanderung war bemerkenswert ambivalent: In einigen Fällen wurde sie erlaubt und sogar gefördert, in anderen wiederum wurde sie kontrolliert und stark eingeschränkt. Die jüdische Auswanderungsbewegung, die in den späten 1960er Jahren entstand und in den 1970er bis 1980er Jahren anhielt, wurde zu einem Beispiel für Widerstand und Aktivismus innerhalb des autoritären Systems, das zunehmend internationale Aufmerksamkeit erregte. Auf die eine oder andere Weise beeinflusste sie das Leben von Hunderttausenden von Menschen und veränderte das Erscheinungsbild vieler Städte und Gemeinden innerhalb und außerhalb der Sowjetunion.

description: We propose and analyze secret key generation using intelligent reflecting surface (IRS) assisted wireless communication networks. To this end, we first formulate the minimum achievable secret key capacity for an IRS acting as a passive beamformer in the presence of multiple eavesdroppers. Next, we develop an optimization framework for the IRS reflecting coefficients based on the secret key capacity lower bound. To derive a tractable and efficient solution, we design and analyze a semidefinite relaxation (SDR) and successive convex approximation (SCA) based algorithm for the proposed optimization. Simulation results show that employing our IRS-based algorithm can significantly improve the secret key generation capacity for a wide-range of wireless channel parameters.

description: Thirlwall’s 1979 balance of payments constrained growth model predicts that a country’s long run growth of GDP can be approximated by the ratio of the growth of real exports to the income elasticity of demand for imports assuming negligible effects from real exchange rate movements. The paper surveys developments of the model since then, allowing for capital flows, interest payments on debt, terms of trade movements, and disaggregation of the model by commodities and trading partners. Various tests of the model are discussed, and an extensive list of papers that have examined the model is presented. JEL Codes: F32, F40, F43

description: Patients with end stage renal disease require some form of vascular access for treatment, with Arterio-Venous Fistulas (AVF) being the preferred form available due to better patency rates. However, they continue to present complications after creation, leading to early or late failure. While many studies are examining the flow in patient-specific fistulas, they often neglect the influence of vessel compliance on its hemodynamics. The objective of this study is to investigate the effect of wall compliance on the complex hemodynamics of a patient-specific brachio-cephalic AVF and how it differs from a rigid fistula. Particle Image Velocimetry (PIV) was used to capture the flow pattern within the fistula for both steady (Re = 1817) and pulsatile (Reav = 1817, Remax = 2232) flow conditions. The results were compared to rigid model measurements performed under the same Reynolds number. The streamline plots and coefficient of variation results did not differ significantly between the models; however, the non-dimensional velocity and directional variability results did vary between the two fistulas. A difference of pproximately 8% was seen between the two models for both steady and pulsatile flow. The findings of this study suggest that to determine the bulk flow, a rigid model is adequate, but to capture the finer details of the flow, a compliant model is necessary
Criticisms and defences of the balance-of-payments constrained growth model: some old, some new

subject: E12, O41

description: This paper assesses various critiques that have been levelled over the years against Thirlwall’s Law and the balance-of-payments constrained growth model. It starts by assessing the criticisms that the law is largely capturing an identity; that the law of one price renders the model incoherent; and that statistical testing using cross-country data rejects the hypothesis that the actual and the balance-of-payments equilibrium growth rates are the same. It goes on to consider the argument that calculations of the “constant-market-shares” income elasticities of demand for exports demonstrate that the UK (and by implication other advanced countries) could not have been balance-of-payments constrained in the early postwar period. Next Krugman’s interpretation of the law (or what he terms the “45-degree rule”), which is at variance with the usual demand-oriented explanation, is examined. The paper next assesses attempts to reconcile the demand and supply side of the model and examines whether or not the balance-of-payments constrained growth model is subject to the fallacy of composition. It concludes that none of these criticisms invalidate the model, which remains a powerful explanation of why growth rates differ. JEL Codes: E12, O41

description: The efficacy of calcium chloride dips on the storage ability of 'Julie' mangoes and of polyethylene film wrapping or the storage ability of 'Jaffa' oranges are reported. Ripening as determined by peel colour development and textural softening was retarded in calcium treated versus untreated 'Julie' mangoes, and an organoleptic evaluation indicated an improvement in consumer satisfaction of calcium treated fruit. Calcium chloride treatment extended the shelf life of fruits to 14 days compared to a 5 day shelf life in untreated fruit. Film wrapping retarded the commercial deterioration and fresh weight loss of 'Jaffa' oranges held at 15 °C and under ambient conditions and thus improved the storage life and marketability of fruits. Juice quality was not adversely affected by film wrapping. Despite the improvement in the commercial quality, marketability and storage life of film wrapped versus unwrapped fruits, the data indicated that storage temperature is of greater importance in the keeping quality of 'Jaffa' oranges than film wrapping in polyethylene. The longest storage life of 126 days was observed in film wrapped fruit held at 15 °C compared to a storage life of 16 days in unwrapped fruit held under ambient conditions.

description: We study the clustering properties of X-ray sources detected in the wide area ($\sim 2 $deg$^{2}$) bright, contiguous XMM-{\em Newton}/2dF survey. We detect 432 objects to a flux limit of $5\times 10^{-15}$ ergcm$^{-2}$s$^{-1}$ in the soft 0.5-2 keV band. Performing the standard angular correlation function analysis, a $\sim 3σ$ correlation signal between 0 and 150 arcsec is detected: $w(θ<150^{''})\simeq 0.114\pm 0.037$. If the angular correlation function is modeled as a power law, $w(θ)=(θ_{\circ}/θ)^{γ-1}$, then for its nominal slope of $γ=1.8$ we estimate, after correcting for the integral constraint and the amplification bias, that $θ_{\circ}\simeq 10.4 \pm 1.9$ arcsec. Using a clustering evolution model which is constant in comoving coordinates ($ε=-1.2$), a luminosity dependent density evolution model for the X-ray luminosity function and the concordance cosmological model ($Ω_{\rm m}=1-Ω_Λ=0.3$) we obtain, by inverting Limber's integral equation, a spatial correlation length of $r_{\circ}\sim 16$ $h^{-1}$ Mpc. This value is larger than that of previous {\sc ROSAT} surveys as well as of the optical two-degree quasar redshift survey. Only in models where the clustering remains constant in physical coordinates ($ε=-3$), do we obtain an $r_{\circ}$ value ($\sim 7.5$ $h^{-1}$ Mpc) which is consistent with the above surveys.

The remarkable durability of Thirlwall’s Law

description: This paper contemplates the robustness of Thirlwall’s Law, a parsimonious expression that relates long run equilibrium growth in any one region to the product of world income growth and the ratio of the income elasticities of demand for exports and imports. Various extensions of the balance-of-payments-constrained growth model from which Thirlwall’s Law is derived are contemplated. In each case, Thirlwall’s Law is shown to reassert itself as a good approximation of the equilibrium growth rate. It is hypothesized that this robustness helps explain the widespread empirical success of Thirlwall’s Law. JEL Codes: O41, E12

Comparing the effectiveness of CO₂ strippers to reduce operating costs for struvite formation
Creators: name: Sabrina, Nandini
Publisher: name: University of British Columbia
Year: 2011

description: Struvite crystallization offers the potential of removing phosphorus from wastewater and recovering it in a form that can be used as a fertilizer. In 1999, the Department of Civil Engineering at the University of British Columbia (UBC) started a phosphorus recovery project. The UBC struvite group is now researching ways to reduce the operating costs of struvite production. One of the major operational costs of struvite production is the cost of caustic chemicals that is added to obtain a desired level of operative pH. The main objective of this research was to introduce two types of CO₂ strippers into the struvite crystallization process and determine their effectiveness in reducing caustic chemical use, thereby helping to reduce the operational costs of struvite production. In this study, two CO₂ strippers were used - (i) compact media stripper and (ii) cascade stripper. The strippers were connected to two identical struvite crystallizers. The reactors were placed at the Lulu Island Wastewater Treatment Plant (LIWWTP). The strippers were tested under different operating conditions, and their effectiveness in reducing caustic use was compared. Throughout the project, a high percentage of phosphorus removal was achieved under each condition, by both the reactors/strippers. Most of the time, the phosphorus removal rate was around 90%. The compact media stripper failed to save any amount of caustic, regardless of the operating conditions. Instead, more caustic was required once the stripper was introduced. One of the reasons was that the stripper blocked the passage of stripped off CO₂, since it was mounted on top of the clarifier. Another reason was the susceptibility of stripper's packing media to become frequently clogged, which also resulted in blocking the movement of CO₂ through the stripping tower. On the other hand, the cascade stripper was very effective in saving caustic. The amount of caustic saved by this stripper ranged from 35% to 86%, depending on the operating conditions. Both strippers showed very poor performance regarding ammonia stripping, with the compact media stripper being slightly better in stripping ammonia. The harvested struvite pellets from both the reactors were composed of nearly pure struvite (94% by mass), with a small amount of calcium and traces of iron and potassium. Different operating conditions did not have any affect on the quality of harvested struvite.
Fixed-order strong H-infinity control of interconnected systems with time-delays

description: We design fixed-order strong H-infinity controllers for general time-delay systems. The designer chooses the controller order and may introduce constant time-delays in the controller. We represent the closed-loop system of the plant and the controller as delay differential algebraic equations (DDAEs). This representation deals with any interconnection of systems with time-delays without any elimination techniques. We present a numerical algorithm to compute the strong H-infinity norm for DDAEs which is robust to arbitrarily small delay perturbations, unlike the standard H-infinity norm. We optimize the strong H-infinity norm of the closed-loop system based on non-smooth, non-convex optimization methods using this algorithm and the computation of the gradient of the strong H-infinity norm with respect to the controller parameters. We tune the controller parameters and design H-infinity controllers with a prescribed order or structure.

description: The post-WW II Jewish migration from the Soviet Union (and also after its dissolution) is one of the largest in modern history. Altogether 2.75 million Soviet Jews left the USSR for Israel, the United States, Germany and elsewhere. The position of the Soviet state with respect to emigration was remarkably ambivalent: in some cases, it was allowed and even encouraged, in others, others; it was controlled and strongly limited. The Jewish emigration movement that arose in the late 1960s and continued throughout the 1970s-1980s became an example of resistance and activism within the authoritarian system, which increasingly alerted international attention. In one way or another, it affected the lives of hundreds of thousands of people and changed the appearance of many cities and towns within the Soviet Union and outside it.
