description: This article examines the critical role that parents play in the bilingual development of young children, focusing on strategies like the OPOL approach and the challenges they face in maintaining bilingualism. Based on interviews and surveys, the article highlights the importance of consistency, cultural reinforcement, and creating a linguistically rich environment to support balanced language acquisition. The findings also emphasize the potential obstacles posed by dominant language environments and parental proficiency in both languages, while underscoring the long-term benefits of parental involvement in fostering bilingualism and bicultural identity.

Line profiles of accretion disks around black holes in Schwarzschild-de Sitter and Einstein-Yang-Mills spacetimes
Creators: name: Slobodov, Sergei
Publisher: name: University of British Columbia
Year: 2009

description: We investigate the characteristic peaks in the iron line profile in the black hole accretion disk X-ray spectrum in two static spherically symmetric metrics, Schwarzschild-de Sitter metric and the Einstein-Yang-Mills black hole metric. For the Schwarzschild-de Sitter metric our results show that for a fixed mass black hole, the peaks become less pronounced and closer together with increasing cosmological constant A. This effect is mainly due to the slower rotational velocity of Keplerian orbits at large radii in the Schwarzschild-de Sitter spacetime as compared to that for the Schwarzschild spacetime. This change of the iron line profile is similar to that obtained from extending the accretion disk size or reducing the emission power law exponent in the Schwarzschild black hole accretion disk models. Based upon the current estimates of A, black holes of at least 1018 solar masses are required to make the effect observable. For Einstein-Yang-Mills black holes, the line profiles depend strongly on the horizon radius and the solution number n. For n = 1 the profile is similar to that of a Schwarzschild black hole. In contrast, the shallow slope of the g00 component of the metric for n = 2,3,4 solutions increases the line width for these solutions significantly, in some cases creating a second pair of peaks redshifted approximately by a factor of 2, breaking the usual correspondence between the position of the blue peak and the black hole mass. The line profiles of solutions for n = 5 — 8 and higher, depending on the horizon radius, closely resemble that of extreme Reissner-Nordstrom black hole. In addition, due to an island of orbit stability near the Einstein-Yang-Mills black-hole horizon for the solutions with small horizon radius r/, there is an extra pair of peaks in the line profile redshifted by a factor of 30 times or more relative to the main line. These features might be used to distinguish accreting Einstein-Yang-Mills black holes from Schwarzschild and Kerr black holes.

description: The liquid xenon (LXe) time projection chamber (TPC) technology is probing a wide range of dark matter masses from sub-GeV to a few TeV. To further improve its sensitivity to sub-GeV dark matter and its application in reactor neutrino monitoring via coherent elastic neutrino-nucleus scattering (CEvNS), more understanding and suppression of single/few electrons background rate are needed. Here we report on the design and performance of a sealed LXeTPC with a graphene-coated fused silica window as the cathode. The purpose of the sealed TPC is for isolating the liquid xenon target volume from the majority of out-gassing materials in the detector vessel, thus improving the liquid xenon purification efficiency and reducing the impurity-induced single/few electrons background. We investigated the out-gassing rate and purification efficiency using the data from the sealed TPC with a simple purification model. The single electron signals from the photoionization of impurities in LXe are obtained and their correlation with the LXe purity is investigated. The photo-electron emission rate on the graphene-coated electrode is compared to that from stainless steel, the electrode material typically used in LXe detectors. We discuss the possible further improvement and potential applications of the sealed TPC for the next generation liquid xenon experiments for dark matter and neutrino physics.

description: We present a general extension of a field-theoretic approach developed in earlier papers to the calculation of the free energy of symmetrically layered electrolytic systems which is based on the Sine-Gordon field theory for the Coulomb gas. The method is to construct the partition function in terms of the Feynman evolution kernel in the Euclidean time variable associated with the coordinate normal to the surfaces defining the layered structure. The theory is applicable to cylindrical systems and its development is motivated by the possibility that a static van der Waals or thermal Casimir force could provide an attractive force stabilising a dielectric tube formed from a lipid bilayer, an example of which are t-tubules occurring in certain muscle cells. In this context, we apply the theory to the calculation of the thermal Casimir effect for a dielectric tube of radius $R$ and thickness $δ$ formed from such a membrane in water. In a grand canonical approach we find that the leading contribution to the Casimir energy behaves like $-k_BTLκ_C/R$ which gives rise to an attractive force which tends to contract the tube radius. We find that $κ_C \sim 0.3$ for the case of typical lipid membrane t-tubules. We conclude that except in the case of a very soft membrane this force is insufficient to stabilise such tubes against the bending stress which tend to increase the radius. We briefly discuss the role of lipid membrane reservoir implicit in the approach and whether its nature in biological systems may possibly lead to a stabilising mechanism for such lipid tubes.

title: Changing our brains and minds: exploring the effects of individual differences in bilingual language experience on brain structure, function, and cognition
Creators: name: DeLuca, Vince F.
Publisher: name: University of Reading
Year: 2018

description: Current research suggests that bilingualism affects both the structure of the brain and several cognitive processes. However, few studies have specifically examined effects of individual differences in bilingual language use on domain-general control processes and their neural correlates. This thesis project assesses the hypothesis that specific language use factors within the bilingual experience will alter neural activity and plasticity in regions implicated in language/executive control. Three studies are run. The first study is longitudinal, examining effects of long-term linguistic immersion on neural plasticity in highly proficient non-native (L2) speakers of English. Data from this study shows adaptations in brain structure related to increased efficiency of language processing and control and modulated by the length of L2 use prior to the study. The second and third studies are cross-sectional, examining effects of specific language use factors on 1) neural structure and intrinsic functional connectivity and 2) performance and neural activation patterns on executive function tasks. Factors related to duration of L2 use correlate to neurocognitive adaptations suggesting increased efficiency in language control. Factors related to extent of L2 use correlate to neurocognitive adaptations suggesting increased language control demands. Considered together, the data suggest that the brain constantly strives to be maximally effective and efficient in language processing control, which in turn affects domain-general cognitive processes. Crucially, the data highlight the necessity of considering specific, individual language experiences in assessing neurocognitive effects of bilingualism.

description: Based on first principles calculations, we show that $Mn$ impurities are magnetic in $MgB_{2}$ due to exchange-splitting of $d_{3z^2-1}$ band and they substantially modify $B$ $p_σ$ and $p_π$ bands through hybridization. Thus, $Mn$ impurities could act as strong magnetic scattering centers leading to pair-breaking effects in $MgB_{2}$. In contrast, we find $Fe$ impurities in $MgB_{2}$ to be nearly non-magnetic.

description: Free volume pockets or voids are important to many biological processes in cell membranes. Free volume fluctuations are a prerequisite for diffusion of lipids and other macromolecules in lipid bilayers. Permeation of small solutes across a membrane, as well as diffusion of solutes in the membrane interior are further examples of phenomena where voids and their properties play a central role. Cholesterol has been suggested to change the structure and function of membranes by altering their free volume properties. We study the effect of cholesterol on the properties of voids in dipalmitoylphosphatidylcholine (DPPC) bilayers by means of atomistic molecular dynamics simulations. We find that an increasing cholesterol concentration reduces the total amount of free volume in a bilayer. The effect of cholesterol on individual voids is most prominent in the region where the steroid ring structures of cholesterol molecules are located. Here a growing cholesterol content reduces the number of voids, completely removing voids of the size of a cholesterol molecule. The voids also become more elongated. The broad orientational distribution of voids observed in pure DPPC is, with a 30% molar concentration of cholesterol, replaced by a distribution where orientation along the bilayer normal is favored. Our results suggest that instead of being uniformly distributed to the whole bilayer, these effects are localized to the close vicinity of cholesterol molecules.
Recomposing remnant industrial land : Union Bay, BC
Creators: name: De Greeff, Paul Thomas
Publisher: name: University of British Columbia
Year: 2009

description: Union Bay is a small community of 650 people located on the east coast of Vancouver Island, BC. At the turn of the century and during the early stages of development in the province of British Columbia, Union Bay played an important role as a shipping port for coal mined at Cumberland 13 miles to the northwest. Today, the town of Union Bay remains as a picturesque seaside settlement, but the waterfront site of the old coal wharf facilities and industrial buildings that once bustled with activity now rests idle. Much speculation has existed over how the historic industrial site in Union Bay should be restored, or to what use the land should be put. This project attempts to move beyond speculation, and to propose a tangible vision for the future use of the site so that it contributes once again to the overall health of the region. Contained in the report is a body of work that investigates the physical constraints of the former industrial lands, as well as cultural biases that might affect a development proposal for the site. Using this background research as a basis, a development proposal for the 101 acres (41 hectares) is presented. Highlights of the development proposal include the establishment of a pedestrian oriented village centre that envelopes a marina development in the sheltered waters of Union Bay. Higher density residential development is aggregated in clusters around the village centre, with one residential cluster proposed for the northwest portion of the site. A park is proposed for the remainder of the site, with an integrated trail system that links park amenities and development clusters together. Although the various aspects of the development proposal are supported by site observations and research, the project represents a qualitative assessment of what could happen with the abandoned industrial lands at Union Bay. As such, the proposal reflects various theoretical and physical landscape precedents, as well as the personal values of the author. It is hoped the project will stimulate discussion with respect to the site, and will help to generate ideas that could lead to the development of a healthy and enjoyable landscape.

description: Recent advances in artificial intelligence (AI) offer an opportunity for the adoption of self-driving networks. However, network operators or home-network users still do not have the right tools to exploit these new advancements in AI, since they have to rely on low-level languages to specify network policies. Intent-based networking (IBN) allows operators to specify high-level policies that dictate how the network should behave without worrying how they are translated into configuration commands in the network devices. However, the existing research proposals for IBN fail to exploit the knowledge and feedback from the network operator to validate or improve the translation of intents. In this paper, we introduce a novel intent-refinement process that uses machine learning and feedback from the operator to translate the operator's utterances into network configurations. Our refinement process uses a sequence-to-sequence learning model to extract intents from natural language and the feedback from the operator to improve learning. The key insight of our process is an intermediate representation that resembles natural language that is suitable to collect feedback from the operator but is structured enough to facilitate precise translations. Our prototype interacts with a network operator using natural language and translates the operator input to the intermediate representation before translating to SDN rules. Our experimental results show that our process achieves a correlation coefficient squared (i.e., R-squared) of 0.99 for a dataset with 5000 entries and the operator feedback significantly improves the accuracy of our model.

description: We present a parallel profiling tool, GAPP, that identifies serialization bottlenecks in parallel Linux applications arising from load imbalance or contention for shared resources . It works by tracing kernel context switch events using kernel probes managed by the extended Berkeley Packet Filter (eBPF) framework. The overhead is thus extremely low (an average 4% run time overhead for the applications explored), the tool requires no program instrumentation and works for a variety of serialization bottlenecks. We evaluate GAPP using the Parsec3.0 benchmark suite and two large open-source projects: MySQL and Nektar++ (a spectral/hp element framework). We show that GAPP is able to reveal a wide range of bottleneck-related performance issues, for example arising from synchronization primitives, busy-wait loops, memory operations, thread imbalance and resource contention.

Spectral density of the noise at high frequencies is roughly proportional to the qubit excitation energy.

title: Vegetation recovery of saltmarsh and sand dune habitat following cable and pipeline installation
Creators: name: Denning, Louise
Publisher: name: University of Reading
Year: 2018

description: This project focuses on post-construction vegetation recovery of saltmarsh and sand dunes following the installation of offshore cables and pipelines. With an increased reliance on renewable energy, sensitive coastal habitats are likely to be subject to future impacts. Past projects can provide a useful record of change to help determine vegetation recovery in terms of time frames and naturalness. The overall aim of the project is to provide evidence to aid the decision-making process. Central to this research is determining which attributes of restored vegetation might best reflect recovery, how long does recovery take, and what are the likely recovery outcomes. Detailed botanical surveys were completed on and off the pipeline and across different vegetation zones. Species data were initially analysed using a Generalised Linear Model, with subsequent ordination using Canonical Correspondence Analysis. Tentative recovery times are provided. These time frames are indicative as each site and construction project is dependent on the vegetation zones and community types present, construction methods, severity of impact and restoration techniques used. With recovery taking anything from 10 years where impacts are less severe (i.e. in the driftline, low-mid marsh, and pioneer marsh) to much longer recovery times >25 years in sensitive vegetation types (i.e. midupper marsh, dune slacks) or where there have been greater impacts. The study found that sand dunes were generally more resilient to construction than saltmarsh, with the exception of dune slacks which typically became drier resulting in a loss of wet-tolerant herbs. In sand dunes there are opportunities to have a positive impact e.g. creating scrapes, or open areas with bare sand supporting early successional species. In saltmarsh, impacts associated with construction tended to be more severe (e.g. compaction, changes in topography and modification of creeks), often resulting in atypical development of early successional marsh.

description: Recent critiques contend “Far too much current writing on photography—even in pieces about social media and photography—fixate on professional photographers,” so this piece seeks to buck that trend by focusing on ordinary smartphone owners and how they use their mobile devices to capture or create, stylize, and represent their worlds. More specifically, this study examines the “life cycle” of images from capture or creation on the device to potential editing and sharing on social media. It does so through a multi-method, qualitative approach that blends an examination of the users’ camera rolls and images they post to social media platforms with in-depth interviews to contexualize and explain their practices. The results indicate that the ordinary individuals in this sample created vastly more images than they shared and that they used their mobile devices chiefly to preserve memories, document new or unusual experiences, preserve inspiration, provide accountability or evidence, and to create visual media as a stand-in for verbal communication. Of the images they did share, ones with common reference points were most likely to be distributed, followed by ones showing new, rare or unusual experiences, ones that were unified or consistent with other images previously posted, and images that flattered the uploader.

description: Poverty reduction among smallholders has remained a major priority for the Kenyan government. Efforts have been geared to have a streamlined agri-business system like emulated by the tea sub-sector. In the smallholder tea sub-sector, farmers are organized to private companies, owns factories, engage in produce assembling, processing, contract experts for profession services, have micro-financing institutions serving them, and procure fertilizer from overseas in bulk to distribute it to its members. While the success of the organization and operations are visible the impact of the enterprise returns are unknown. The paper discusses the tea farming enterprise contribution to the well being of the smallholders’ tea farmers in central and western highlands of Kenya.

description: To cope with the unprecedented surge in demand for data computing for the applications, the promising concept of multi-access edge computing (MEC) has been proposed to enable the network edges to provide closer data processing for mobile devices (MDs). Since enormous workloads need to be migrated, and MDs always remain resource-constrained, data offloading from devices to the MEC server will inevitably require more efficient transmission designs. The integration of nonorthogonal multiple access (NOMA) technique with MEC has been shown to provide applications with lower latency and higher energy efficiency. However, existing designs of this type have mainly focused on the transmission technique, which is still insufficient. To further advance offloading performance, in this work, we propose an application-driven NOMA enabled computation offloading scheme by exploring the characteristics of applications, where the common data of the application is offloaded through multi-device cooperation. Under the premise of successfully offloading the common data, we formulate the problem as the maximization of individual offloading throughput, where the time allocation and power control are jointly optimized. By using the successive convex approximation (SCA) method, the formulated problem can be iteratively solved. Simulation results demonstrate the convergence of our method and the effectiveness of the proposed scheme.

description: A complete and critical survey is presented of all half-life, decay-energy and branching-ratio measurements related to 20 superallowed decays; no measurements are ignored, though some are rejected for cause and others updated. A new calculation of the statistical rate function is described and experimental ft values determined. The associated theoretical corrections needed to convert these results into Ft values are discussed, and careful attention is paid to the origin and magnitude of their uncertainties. As an exacting confirmation of the conserved vector current hypothesis, the Ft values are seen to be constant to 3 parts in 10^4. These data are also used to set new limits on any possible scalar interactions or right-hand currents. The average Ft value obtained from the survey, when combined with the muon lifetime, yields the CKM matrix element Vud = 0.9738(4); and the unitarity test on the top row of the matrix becomes |Vud|^2 + |Vus|^2 + |Vub|^2 = 0.9966(14) using the PDG's currently recommended values for Vus and Vub. We discuss the priorities for future theoretical and experimental work with the goal of making the CKM unitarity test more definitive.

description: As humans, we are uniquely competent at incorporating ourselves into groups that scale up from a few members to millions of individuals to engage in joint activities in social circles of varying sizes. Yet, the question of how a group's survival depends on its social structure is not well understood. In an analysis of more than 10 122 real-life online communities (with a total of 134 147 members) hosted by a leading platform over periods of more than a decade, we observe a prominent structural difference between stable and unstable communities, enabling the prediction of sustainability up to a decade ahead. We find that communities that fail to maintain a typical hierarchical social structure that preserves cohesiveness across size scales do not survive, while communities that exhibit such balance prevail. This difference is observable in as early as the first 30 days of a community's lifetime, enabling prediction of community sustainability up to 10 years in the future. We theorize that communities comprised of distinct social structures that balance global and local factors across scales of sizes are more likely to maintain sustainability.

description: The study assesses farmers’ perceptions and willingness to pay for a biopesticide developed from Metarhizium anisopliae a fungi. A sample of 400 conventional and organic cotton producers was randomly selected in cotton producing zones in Benin and interviewed for their perceptions on the efficacy of the biopesticide and the likely prices they are willing to pay for the product to control a major pest like Helicoverpa armigera or cotton bollworm causing substantial crop losses. An econometric model (Logit) is used to identify factors highly likely to affect farmer’s willingness to purchase the product. The results show that Helicoverpa armigera or cotton bollworm is perceived by farmers as the most severe pest with losses reaching up to 100%. Farmers attribute the current pest intensity to a number of factors including ineffectiveness of chemical pesticides, delay in access to input mainly fertilizers and the development of refuge host plants for cotton pests. The results also show that most cotton producers and their households members are exposed to chemical insecticides without adequate protection devices during the pest control sprays. Both organic and conventional cotton producers have expressed a significant interest in the use of Metarhizium to control Helicoverpa on cotton. Both types of farmers willing to pay more for any pest control product that would improve cotton product quality for higher cotton price. Three variables influencing farmers’ willing to pay for biopesticides from Metarhizium were efficacy, agro-ecological zone and broad spectrum.

description: We calculate the electromagnetic form factors of the nucleon up to fourth order in manifestly Lorentz-invariant chiral perturbation theory with vector mesons as explicit degrees of freedom. A systematic power counting for the renormalized diagrams is implemented using both the extended on-mass-shell renormalization scheme and the reformulated version of infrared regularization. We analyze the electric and magnetic Sachs form factors, $G_E$ and $G_M$, and compare our results with the existing data. The inclusion of vector mesons results in a considerably improved description of the form factors. We observe that the most dominant contributions come from tree-level diagrams, while loop corrections with internal vector meson lines are small.

Book Review: Theorizing Images by Žarko Paić and Krešimir Purgar (Eds.)
Creators: name: Thomson, T.J.
Publisher: name: figshare

Subjects: subject: 190104 Visual Cultures
subject: FOS: Arts (arts, history of arts, performing arts, music)

description: Overall, Theorizing Images is, in many places, an impressive synthesis of the highly interdisciplinary landscape of visual studies. Scholars needing a foundation in visual culture would benefit from this text, as would those needing to give voice to the often-unnamed or poorly explored relationships among objects, time, language, and meaning-making. The text is hampered, in places, by its Eurocentric focus and the language and cultural barriers that are occasionally presented but not resolved, yet all readers will likely find a good portion of the text evocative and resonant, even if not all the chapters possess the same intellectual heft, narrative elegance, or theoretical sophistication.

description: Бухоро амири Ҳайдар (1800 – 1826) шоир ва олим ҳукмдор бўлган.[1] Муҳаммадҳакимхон Тўра “Мунтахаб ат-таворих”да ёзишича, “ўзбек подшоҳлари ичида амир Ҳайдар подшоҳ каби хафсалали олим ва бировнинг ҳаққидан ҳазар қилгувчи ўтмаган. Бир неча пири комилдан иршодлик хати олиб, сулук қоидаларини мукаммал ўзлаштирган эди”.[2] Амир Ҳайдар  “Саййид” ва “Саййидий” тахаллуслари билан шеърлар машқ қилган.[3] Манбаларга кўра,  “отаси (Амир Шоҳмурод)нинг асрида Қарши волийси эканда, Мулло Миракхон Ан-Насафийдин таълими илм қилиб, Бухорода мулло Фахриддин бин Иброҳимдин ахзи қироат қилиб, ҳофизи Қуръон бўлғон эди, деб халқ орасида машҳур эди. Гарчанд нитоқи мулки давлати заййиқу қосир ва қуввати тасаллут ва иқтидори заиф ва фотир бўлса ҳам умури мамлакатни халифаи бани аббосия услубида, хусусан, Хорун ар-Рашидға тақлид қилур эди. Турк султонларидин султон Ал-Маҳмуд бин Абдулҳамидхонни халифа деб изҳори итоат қилур эди.

description: In this paper we give an example of a noncongruence subgroup whose three-dimensional space of cusp forms of weight 3 has the following properties. For each of the four residue classes of odd primes modulo 8 there is a basis whose Fourier coefficients at infinity satisfy a three-term Atkin and Swinnerton-Dyer congruence relation, which is the $p$-adic analogue of the three-term recursion satisfied by the coefficients of classical Hecke eigen forms. We also show that there is an automorphic $L$-function over $\mathbb Q$ whose local factors agree with those of the $l$-adic Scholl representations attached to the space of noncongruence cusp forms.

Book review: Photography: A Critical Introduction (Fifth Edition), edited by Liz Wells
Creators: name: Thomson, T.J.
Publisher: name: figshare

Subjects: subject: 190104 Visual Cultures
subject: FOS: Arts (arts, history of arts, performing arts, music)

description: The desire and necessity to visually document, analyze, and interact with our social world is timeless and so a text that tries to explore one aspect of visual production, evaluation, and interaction—photography—and trace its almost 200-year evolution is a massive and formidable task indeed. Photography: A Critical Introduction, edited by Liz Wells, accepts this challenge and steeps the reader in a thorough understanding of the field's major philosophical players, including Baudelaire, Barthes, Berger, Benjamin, Burgin, Flusser, Kracauer, Eco, Moholy-Nagy, Ohrn, Sontag, Szarkowski, and Trachtenberg. It also admirably provides insight on something so generic, widespread, ubiquitous, and ever-changing—photographic use—with theoretical insights like “photographs can exhaust experiences, using up the beautiful through rendering it into cliché” (p. 33).

description: By inspecting some known solutions to Einstein equations, we present the metric of higher dimensional Reissner-Nordstr$\ddot{o}$m black hole in the background of Friedman-Robertson-Walker universe. Then we verify the solution with a perfect fluid. The discussion of the event horizon of the black hole reveals that the scale of the black hole would increase with the expansion of the universe and decrease with the contraction of the universe.

Η μελέτη περιλαμβάνει την ανάλυση της υφιστάμενης κατάστασης, τη συλλογή δεδομένων για την κυκλοφορία οχημάτων και πεζών, καθώς και τις απόψεις των καταστηματαρχών της περιοχής. Στα πρώτα κεφάλαια παρουσιάζονται βασικά χαρακτηριστικά της περιοχής μελέτης, οι θεωρητικές αρχές της πεζοδρόμησης και τα οφέλη που παρέχει σε οικονομικό, κοινωνικό, περιβαλλοντικό επίπεδο αλλά και σε σχέση με την κυκλοφορία. Στη συνέχεια αναλύονται επιτυχημένες πρακτικές που ακολουθούν πόλεις στην Ευρώπη και κατευθυντήριες γραμμές της Ευρωπαϊκής Ένωσης. Στη συνέχεια, μέσω μετρήσεων και ερωτηματολογίων συλλέχθηκαν δεδομένα και έπειτα από την ανάλυση των αποτελεσμάτων αναδεικνύεται η ανάγκη για την πεζοδρόμηση, καθώς παρατηρείται αυξημένη κίνηση πεζών και θετική ανταπόκριση από το μεγαλύτερο ποσοστό των τοπικών επιχειρηματιών. Μέσω της ανάλυσης των αποτελεσμάτων της έρευνας των ερωτηματολογίων, της μέτρησης κυκλοφοριακού φόρτου και της επιτόπιας έρευνας πραγματοποιήθηκε αξιολόγηση της υφιστάμενης κατάστασης. Η εργασία καταλήγει σε προτάσεις που αφορούν την επερχόμενη πεζοδρόμηση, οι οποίες βασίζονται στα αποτελέσματα της έρευνας, για τη βελτίωση του σχεδιασμού της πεζοδρόμησης, με στόχο τη βιώσιμη ανάπτυξη της περιοχής και τη βελτίωση της ποιότητας ζωής των κατοίκων και επισκεπτών.
description: This thesis focuses on the expansion of the pedestrian street of Agia Sophia in Thessaloniki, in the section between Tsimiski Street and Leoforo Nikis Street. The study includes the analysis of the current situation, the collection of data on vehicle and pedestrian traffic and the opinions of the shopkeepers in the area. The first chapters present the basic characteristics of the study area, the theoretical principles of pedestrianization and the benefits it provides at an economic, social, environmental level but also in relation to traffic. Then, successful practices followed by cities in Europe and guidelines of the European Union are analyzed. Also, through measurements and questionnaires, data were collected and after the analysis of the results, the need for pedestrianization is highlighted, as increased pedestrian traffic and a positive response from the majority of local entrepreneurs are observed. Through the analysis of the results of the questionnaire survey, traffic load measurement and on-site research, an assessment of the current situation was carried out. The work concludes with proposals regarding the upcoming pedestrianization, which are based on the results of the research, to improve the pedestrianization design, aiming at the sustainable development of the area and improving the quality of life of residents and visitors

description: Drought is endemic to southern Africa. In Zimbabwe farmers have been experiencing drought once every two to three years. Relief agencies have traditionally responded to drought by providing farmers with enough seed and fertilizer to enable them to re-establish their cropping enterprises. But, in the absence of these interventions there are limited sustainable options for farmers to maintain higher productivity levels. ICRISAT has been working with government, NGOs and the donor community to test more sustainable farming strategies that will increase food production levels even under drought conditions. For years, ICRISAT sought to develop more drought-tolerant varieties of sorghum, pearl millet and groundnut. But these offered only limited gains in productivity. More recently, ICRISAT and its partners have been testing strategies to sustainably improve crop productivity. These encompass two major components – conservation farming techniques that include the use of planting basins, which concentrate limited water and nutrient resources to the plant, and the precision application of small doses of nitrogen-based fertilizer. These simple technologies have increased average yields by 15-75 percent, being obtained by more than 300,000 farm households. Rather than simply handing free inputs to farmers, this strategy teaches farmers how to apply the inputs most efficiently. The pursuit of input-use efficiency provides higher and more sustainable productivity gains necessary to achieve food security in drought-prone farming systems. A farm enterprise budget analysis has been employed to show that it is more viable to adopt conservation farming techniques particularly under drought conditions.
