description: Pine plantations are considered a means of economic sustainability in South Africa. Yet over the years, pine trees can disperse and propagate independently of humans, occurring in natural areas, and have an adverse effect on native plant and invertebrate communities. Due to the ongoing what it seemed important to assess the effect that afforestation have on beetle and spider assemblages, and to assess if cultural landscape can be used to conserve biodiversity. We therefore used beetles and spiders which can act as good surrogates for habitat quality. Three habitat types: pine plantation, grassland, and cultural landscapes were sampled using 180 pitfall traps which were set for seven days (six pitfalls per replicate, ten replicates per habitat). A total of 736 (41 morphospecies) beetles’ and739 spiders including juveniles (36 species) were sampled. Araneae were found to be more abundant and species rich compared to the other species. Lycosidae sp.10 was the most abundant in the remnant grassland with a total of 58 individuals. Similar patterns were observed with the Carabidae and Scarabaeidae morphospecies with the Carabidae sp.01 more abundant in the pine site with a total of 106 individuals, Scarabaeidae sp.01 was most abundant in grassland with a total of 207 individuals, and Tenebrionidae sp.02 was most abundant at the cultural site with 43 individuals. A significant difference in morphospecies composition was found with the beetles and spiders, however there was no significant difference with the spiders between grassland-cultural landscapes, indicating possible persistence of assemblage under adverse conditions. This may be because all spiders sampled for this study are predatory, and are not necessarily affected by change in fragment size and differential disturbance.

description: The effective potential is computed for two boson systems in one trap as a function of their two individual hyperadii and the distance between their centers. Zero-range interactions are used and only relative s-states are included. Existence and properties of minima are investigated as a function of these three collective coordinates. For sufficiently strong repulsion stable structures are found at a finite distance between the centers. The relative center of masses motion corresponds to the lowest normal mode. The highest normal mode is essentially the breathing mode where the subsystems vibrate by scaling their radii in phase. The intermediate normal mode corresponds to isovector motion where the subsystems vibrate by scaling their radii in opposite phase. Stability conditions are established as substantially more restrictive than in mean-field computations.

An investigation of the zoobenthos diversity, in relation to the particle structure of the benthos of the Nandoni Dam
Creators: name: Mashudu Mashau
Publisher: name: Zenodo
Year: 2011
Subjects: Honours

description: The study investigated the structural difference of the benthic zone sediments of various sites in the recently constructed Nandoni Dam and their relation to zoobenthos diversity. Samples were collected with a bottom grab and sieved through a series of sieves in the laboratory. Sediment particle sizes were classified according the mesh sizes of the sieves on which they were trapped. Each sediment sample was microscopically investigated for zoobenthos and the organisms were identified. The results have shown that the composition of the benthic zones at the investigated sites is not the same with a clear distinction between deepwater and inflow sites with more fine material at the latter. This difference is reflected by the zoobenthos diversity with molluscans, annelids and macro-invertebrates dominant at the deepwater sites and annelids and macro-invertebrates at the inflow sites

description: Studies have used a variety of criteria to evaluate the benefits from promotion and, relatedly, to prescribe optimal advertising strategy. Gross benefit measures, that do not account for the costs of the commodity, are clearly inappropriate. Allowing for international or interregional trade, or multiple outlets for a commodity (e.g., fresh and Processing) may mean that net benefits are small or zero. Some questions require Measures that account for other costs and benefits (such as consumer benefits and effects on taxpayers through commodity programs). This paper explores the effects of horizontally disaggregating commodity markets (into domestic and foreign and fresh and Processing), and allowing for market distortions from commodity programs, on producer incentives and on measures of the private and social payoff to advertising financed by a Per unit tax or check-off.
Cost-benefit analysis of Pre-consumed Food Waste and Development of a Food Waste Baseline : A Food Waste Recovery Initiative

description: Pre-consumer food waste (PCFW) is the food waste associated with the preparation of ingredients in dishes and other food products to be sold for consumers. Food waste is a large issue that contributes to global greenhouse gas emissions, and its impact can grow exponentially with the expected increase in the human population by 2050. To help reduce PCFW, the implementation of circular economies should be employed. This can help eliminate waste from ending up in landfills. Our project responds to UBC’s Community Action Plan 2030’s (CAP 2030) aim to reduce campus food waste by 50% before 2030. This research is the first step in meeting this goal and will develop a food waste baseline at Open Kitchen (OK), a residence dining hall at the University of British Columbia through a cost-benefit analysis of PCFW based on its monetary and environmental costs. Our analysis will employ various methods including, literature reviews, in-depth interviews with key staff at UBC Food Services, and quantitative analysis of waste data collected both historically at Open Kitchen, and data collected specifically for this project by Food Services (FS) staff. This analysis aims to provide a clear insight into current practices being done to reduce PCFW. Key promising practices identified from the literature include: limiting self-serve stations and container sizes, staff training on food storage and handling, and incorporating more plant-based menus. These promising practices fall in line with the identified gaps noted in the interview which include: waste occurring mostly at side and salad bars and that there is no standard acceptable amount of food waste set. The results from the cost-benefit analysis show that the greenhouse gas emissions from 2021 are higher in comparison to 2020, and economic costs are highest during September and October for both years. Recommendations are made based on immediate, short (6 months) and long (over 1 year) term goals for UBC Food Services. These include amending the existing food waste recording system, setting acceptable monthly food waste goals and the routines to track them, as well as providing the framework for conducting food waste audits at other locations.

description: We set up a framework for a model-independent analysis of the time variation of $e$, $\hbar$, and $c$ indiviually. It is shown that the time-evolution of each constant can be determined uniquely from the time evolution of the fine structure constant $α$ provided that the choice of basic time-independent units (i.e., the clock and ruler) is fixed. Realistic systems of units are considered as examples and implications for metrology are discussed.

Galactic Binaries as Sources of Gravitational Waves

description: I review the expected Galactic sources of gravitational waves, concentrating on the low-frequency domain and summarise the current observational and theoretical knowledge we have. A model for the Galactic population of close binaries, which is tested against the observations is used to predict the expected signal for the future space based gravitational wave detector LISA. With a simple model for the electro-magnetic emission from the same binaries I argue that a fair number of the LISA systems have electro-magnetic counterparts, which can be used to improve in particular the distance and mass measurements of these systems by LISA. Furthermore, LISA will enable us to test some aspects of the theory of binary evolution that are very difficult to asses in different ways.

description: This work is a follow up of recent investigations, where we study the implications of a generalized heat kernel expansion, constructed to incorporate non-perturbatively the effects of a non-commutative quark mass matrix in a fully covariant way at each order of the expansion. As underlying Lagrangian we use the Nambu -- Jona-Lasinio model of QCD, with $SU_f(3)$ and $U_A(1)$ breaking, the latter generated by the 't Hooft flavour determinant interaction. The associated bosonized Lagrangian is derived in leading stationary phase approximation (SPA) and up to second order in the generalized heat kernel expansion. Its symmetry breaking pattern is shown to have a complex structure, involving all powers of the mesonic fields allowed by symmetry. The considered Lagrangian yields a reliable playground for the study of the implications of symmetry and vacuum structure on the mesonic spectra, which we evaluate for the scalar and pseudoscalar meson nonets and compare with other approaches and experiment.

Capturing the Red Queen using Adaptive Dynamics in a predator-prey coevolution

Subjects: Red Queen

Honours

description: In this paper we describe the coevolution of phenotypes in a community of predators and of prey using adaptive dynamics. Evolutionary cycling can be one of the outcome of the process. The Models on which the description is based are formed from microscopic stochastic birth and death events, together with a process of random mutation. Births and deaths, can occur as a results of phenotype-dependent interactions between predator and prey individuals and therefore natural selection can be generated. We demonstrate three outcomes of evolution in this paper. A community may evolve to a state at which the predator becomes extinct, or to one at which the species coexist with constant phenotypic values, or the species may coexist with cyclic changes in phenotypic values. The last outcome corresponds to a Red Queen dynamic, in which the selection pressures arising from the predator-prey interaction cause the species to evolve without ever reaching an equilibrium phenotypic state. The Red Queen dynamic will require an intermediate harvesting effciency of the prey by the predator and suffciently high evolutionary rate constant of the prey, and is complex when the model is made stochastic and phenotypically polymorphic. A cyclic outcome lies outside the contemporary focus on evolutionary equilibria, and argues for an extension to a dynamical framework for describing the asymptotic states of evolution.

description: We produce and holographically measure entangled qudits encoded in transverse spatial modes of single photons. With the novel use of a quantum state tomography method that only requires two-state superpositions, we achieve the most complete characterisation of entangled qutrits to date. Ideally, entangled qutrits provide better security than qubits in quantum bit-commitment: we model the sensitivity of this to mixture and show experimentally and theoretically that qutrits with even a small amount of decoherence cannot offer increased security over qubits.

description: Raymond Casey was an internationally recognized expert in two entirely different fields—geology and philately. He achieved this despite leaving school at 14. By then he was already collecting and studying fossils from his home town, Folkestone, and in 1939, despite not having a degree, he obtained a post with the Geological Survey of Great Britain in the modest role of assistant to C. J. Stubblefield. After war-time service in the RAF, he returned to the Survey in a similar role, but spent much of his ‘spare time’ researching and publishing on Lower Cretaceous palaeontology and stratigraphy. His fortunes began to change when, at the age of 38, he was admitted to Reading University to study for a doctorate. His thesis on Lower Greensand stratigraphy and palaeontology was recognized as an outstanding study that led to major publications including a nine-part monograph of the ammonite faunas. Then, in the late 1950s, he also began to study faunas from Jurassic–Cretaceous boundary beds in eastern England as part of his official work and this led to him visiting the Soviet Union on several occasions from 1963 onward. On the first visit he met the academician Nalivkin in Leningrad, who, as well as being an eminent geologist, was a keen philatelist. This led to Raymond taking an enthusiastic interest in pre-revolutionary Russian postal history, which resulted in numerous publications and awards and, after his retirement, became his main focus of interest.

His career in the Theoretical Physics Division at the Atomic Energy Research Establishment (AERE) at Harwell was characterized by his outstanding successes in explaining experimental nuclear data. He pioneered the understanding of the important nucleon capture reactions by introducing new mechanisms of direct and semi-direct capture and, together with colleagues, he greatly advanced knowledge of nuclear analogue states, and the role of isospin in nuclear physics. With R. G. Thomas, he wrote a comprehensive review of R-matrix theory, applied to analyse resonances in nuclear reactions, which became one of the most cited papers in physics. His book Nuclear theory gave a good account of the use of pairing force theory in nuclear physics, and its application to nuclear collective motion.

description: We analyze the dynamics of random walks in which the jumping probabilities are periodic {\it time-dependent} functions. In particular, we determine the survival probability of biased walkers who are drifted towards an absorbing boundary. The typical life-time of the walkers is found to decrease with an increment of the oscillation amplitude of the jumping probabilities. We discuss the applicability of the results in the context of complex adaptive systems.

description: 2010 was the "International year of Biodiversity" and was especially important within the Vhembe biosphere reserve of Limpopo province. This initiative was led by the secretariat of the CBD and UNESCO. It was aimed at disseminating information about biodiversity and improving the identification and monitoring of that biodiversity. The present project adapted a method developed for the Iimbovane outreach project to a school in Vuwani, where a citizen science initiative was used to conduct a biodiversity outreach program while simultaneously collecting ant species richness data. The aims of the project were (i) to inventory ant species from Mugoidwa secondary school, (ii) to investigate how species composition from an un-impacted site compared with species from an impacted site over a 12 month period and (iii) to test the effectiveness of the citizen science initiative in promoting biodiversity awareness and understanding. The pitfall method was used to sample ants in an impacted and un-impacted site of the school ground for a year. Grade 11 learners were taught how to sample ants, wash and sort pitfalls and how to use an identification key. Learners were also given lessons in biodiversity. At the end of the project the learners from Mugoidwa secondary school participated in a survey questionnaire along with two other schools. A total of 10577 ants comprising 45 species, 21 genera and 6 subfamilies were identified for study the site. Species composition of the impacted site differed from the un-impacted site. Abundances were also different with the impacted site having higher abundances than the un-impacted site. Each site had species that were unique to them with some species that only occurred on one site contributing to dissimilarities between the sites. Learners successfully participated in the project as citizen scientists and reduced the researcher's workload. Language turned out to be an obstacle in the survey as learners struggled to answer open ended questions.

The project also aimed to partly address South Africa's obligations to the CBD and the aims of UNSECO within the Vhembe biosphere reserve.

description: The radio pulsar B1951+32 and the supernova remnant CTB 80 provide a rich laboratory for the study of neutron stars and supernova remnants. Here, we present ground-based optical and near-infrared observations of them, along with X-ray observations with Chandra and a re-analysis of archival data obtained with the Hubble Space Telescope. The X-ray observations reveal a cometary pulsar wind nebula which appears to be confined by a bow shock produced by high-velocity motion of the pulsar, making PSR B1951+32 a rare pulsar exhibiting both an H alpha bow shock and a shocked X-ray pulsar wind nebula. The distribution of H alpha and radio continuum emission is indicative of a contact discontinuity of the shocked pulsar winds and shocked ambient medium at \~0.05 pc. On the other hand, the optical synchrotron knot of PSR B1951+32 likely has a flat spectrum in the optical and near-infrared wavebands, and our astrometry is consistent with only one of the two reported optical counterpart candidates for the pulsar.

description: The local algebras of the maximal Coset model C_max associated with a chiral conformal subtheory A\subset B are shown to coincide with the local relative commutants of A in B, provided A contains a stress energy tensor. Making the same assumption, the adjoint action of the unique inner-implementing representation U^A associated with A\subset B on the local observables in B is found to define net-endomorphisms of B. This property is exploited for constructing from B a conformally covariant holographic image in 1+1 dimensions which proves useful as a geometric picture for the joint inclusion A\vee C_max \subset B. Immediate applications to the analysis of current subalgebras are given and the relation to normal canonical tensor product subfactors is clarified. A natural converse of Borchers' theorem on half-sided translations is made accessible.

A comparison of HI data with the predictions from tidal models for the SMC evolution suggests that the central region of the SMC corresponds to the central, disk- or bar-like, component left from the rotationally supported SMC disk prior to its last two encounters with the Large Magellanic Cloud. In this scenario, the velocity gradient is expected as a left-over from the original, pre-encounter, angular momentum. We have derived the HI rotation curve and the mass model for the SMC. This rotation curve rapidly rises to about 60 km/s up to the turnover radius of ~3 kpc. A stellar mass-to-light ratio of about unity is required to match the observed rotation curve, suggesting that a dark matter halo is not needed to explain the dynamics of the SMC. A set of derived kinematic parameters agrees well with the assumptions used in tidal theoretical models that led to a good reproduction of observational properties of the Magellanic System. The dynamical mass of the SMC, derived from the rotation curve, is 2.4x10^9 Msolar.

description: The Jordanian Law of Commercial Agents and Intermediaries No. 28 of 2001 covers all forms of sale contracts through intermediaries. This law provides express restrictions and protective provisions on the conduct by local agents of internal commercial agency activities. However, these statutory protections are granted only to registered agencies conducted by national agents. The Jordanian legislation does not regulate the issue of agency exclusivity, which can constitute a restraint of trade and leads to a state of market monopolization. Courts in Jordan have exclusive jurisdiction in settling disputes arising out of agency agreements. However, this exclusive jurisdiction does not cover unregistered commercial agencies, which are treated as enforceable commercial contracts under the general provisions prescribed in the Commercial Code. Under Jordanian law, the principal cannot terminate the agency agreement at any time, but he can decide not to renew it upon the expiry of its date without justified grounds. Certain statutory protections provided by the Jordanian law raise barriers to entry to their national markets. This statutory policy violates the specific commitments made by Jordan with respect to market access and national treatment established by the GATS.

description: We find the metric of small black holes on cylinders, i.e. neutral and static black holes with a small mass in d-dimensional Minkowski-space times a circle. The metric is found using an ansatz for black holes on cylinders proposed in hep-th/0204047. We use the new metric to compute corrections to the thermodynamics which is seen to deviate from that of the (d+1)-dimensional Schwarzschild black hole. Moreover, we compute the leading correction to the relative binding energy which is found to be non-zero. We discuss the consequences of these results for the general understanding of black holes and we connect the results to the phase structure of black holes and strings on cylinders.

description: This paper proposes that transboundary water governance needs to become an essential input to sustainable governance of protected natural reserves. The paper reviews the challenges and opportunities for such governance mechanisms, and identifies the factors behind successful practices. Successful transboundary governance of water and nature requires the reduction of associated transaction costs. Firstly, water diplomacy through joint research, data collection and monitoring, capacity building, dialogues for consensus building, promoting responsible leadership and providing advisory support can help in overcoming mistrust between stakeholders and create opportunities for cooperation. Secondly, power asymmetries may hinder transboundary water governance, therefore, there is a need to involve multi-scale links across stakeholders to counter-balance local power asymmetries and engage all stakeholders in consultations and negotiations. Thirdly, transboundary water governance is critically dependent on accurate and transparent data and analysis tools for informing policy decisions. Science-policy interactions for facilitating transboundary water governance were found to be most effective when the knowledge on joint water and nature governance is co-produced in a trans-disciplinary manner, in collaboration with wide-ranging informal networks of scientists, policy makers, and civil society. Finally, transboundary water governance organizations can serve as platforms for facilitating water diplomacy, building trust and cooperation, especially when they are granted the ability to enter into binding cooperative agreements regardless of external political pressures.

description: There is a need both in organic farming and on farms using integrated pest management for non-chemical measures that control the perennial weed flora. The effect of mechanical weeding and fertilisation on perennial weeds, fungal diseases and soil structure were evaluated in two different experiments in spring cereals. Experiment I included six strategies. The first strategy was (1) without specific measures against perennial weeds. The other strategies encompassed one or two seasonal control measures; (2) rhizome/root cutting with minimal soil disturbance in autumn, (3) hoeing with 24 cm row spacing, (4) combined hoeing and disc harrowing in autumn, (5) ‘KvikUp’ harrowing in spring, and (6) ‘KvikUp’ harrowing in spring and autumn. Experiment II included factor (i) inter-row hoeing and (ii) fertilisation level. This experiment included the comparison between normal row spacing (12 cm) with weed harrowing versus double row spacing (=24 cm) in combination with inter-row hoeing and 4 fertilisation levels (50–200 kg N ha−1). In experiment I the strategies consisting of no or one direct weed control measure (1, 2, 3 and 5) clearly did not control the perennial weeds. The two seasonal control measures (4 and 6) gave a satisfactory weed control and highest crop yield. The combination of best weed control and no measured harmful effects on soil structure or increase of fungal diseases may explain the highest yields for these strategies. In Experiment II, hoeing and 24 cm spacing gave less perennial biomass compared to 12 cm spacing. Grain yields increased linearly with increasing nitrogen input. The study shows that both inter-row hoeing and weed harrows, are important elements in integrated pest management practice and organic farming. In addition, our results indicate that efficient mechanical weeding is possible without harmful effects in crop rotation consisting of various spring cereals as regards soil structure and plant health.

description: The aim of the research was to determine the competitiveness of apple export from Poland to the CIS markets. In the paper the most important producers and net importers of apples from CIS were identified. Using the ex-post measures, the competitive position of Polish exports to selected CIS markets was determined. In 2006-2016, Poland was the largest supplier of apples to Belarus, Kazakhstan and Ukraine, and in 2006-2014 to Russia as well. The competitive position of apple exports from Poland decreased in the years 2014-2015 on the Belarusian market, and increased in the Kazakh and Ukrainian. As a result of the Russian embargo on the import of apples from the EU, the competitive position of supplies from Serbia, China, Moldova and Belarus increased in this market. / Synopsis. Celem badań było określenie konkurencyjności eksportu jabłek z Polski na rynki Wspólnoty Niepodległych Państw. W artykule zidentyfikowano najważniejszych producentów oraz importerów netto z WNP. Przy wykorzystaniu mierników pozycji konkurencyjnej ex-post określono pozycję konkurencyjną eksportu z Polski na wybrane rynki WNP. W latach 2006-2016 Polska była największym dostawcą jabłek na Białoruś, do Kazachstanu oraz na Ukrainę, a w latach 2006-2014 również do Rosji. Pozycja konkurencyjna eksportu jabłek z Polski obniżyła się w latach 2015-2016 na rynku białoruskim, a wzrosła na kazachskim i ukraińskim. W wyniku embarga na import jabłek z UE, wzrosła na rynku Federacji Rosyjskiej pozycja konkurencyjna dostaw z Serbii, Chin, Mołdawii oraz Białorusi.

description: Department of Water Affairs has been removing invasive alien riparian trees along the riparian zones through Working for Water programme since 1995. In this study we assess the progress of the programme by studying the response of benthic macroinvertebrates and adult odonata to alien invasive clearing. We tested if clearing affected the SASS, DBI, ASPT and adult odonata species richness. The study area is in the upper reaches of the Luvuvhu river catchment in Limpopo province (South Africa). A total of 46 invertebrates families were sampled at total of 13 sampling units. The results suggest that clearing has a positive impact on benthic macroinvertebrates with all metrics increasing with an increase in number of times cleared, although the only result that was significant was that of ASPT. The adult Odonata metrics were negatively impacted by clearing and positively by increased canopy and alien cover. These results should however be viewed as preliminary as only one correlation, the positive impact of clearing on ASPT scores, was significant (F2, 10= 0.53, p= 0.6). Seventeen adult Odonata species were recorded from natural, alien and cleared sites. The objective of the study is to test whether clearing intensity of invasive alien plants cover affects SASS, DBI, ASTP, Odonata species richness, and to collect a reference collection of adult Odonata species.

description: Quantum algorithms are built enabling to find Poincaré recurrence times and periodic orbits of classical dynamical systems. It is shown that exponential gain compared to classical algorithms can be reached for a restricted class of systems. Quadratic gain can be achieved for a larger set of dynamical systems. The simplest cases can be implemented with small number of qubits.
