description: A development goal pursued by the Zimbabwean government even before the much-maligned fast track land reform programme (FTLRP) was expansion of agricultural production through agricultural mechanization. This goal has been pursued through the acquisition and use of tractors by arable crop farmers in communal and resettlement state land delineated during the period following the launch of the FTLRP. This research project investigated the combined impacts of mechanization and an unplanned land reform on agricultural productivity in the Bindura district of Zimbabwe. The existing land policy and the issue of technical efficiency in agricultural productivity are assumed to be the drivers of the programme. It is likely that these issues will be important considerations in determining the sustainability of the mechanization policy. A multistage sampling technique was used to randomly select 90 farmers in the study area and structured questionnaires were used to collect demographic, investment and production data which were subsequently fitted by means of the Stochastic Frontier Model. Results revealed that mechanization was an important factor in the performance of the farmers who participated in the programme. The results also suggest that availability of land and access to production resources are crucial to farm productivity. Despite these, overall production and productivity remain low and the hyperinflationary situation triggered by supply constraints are only beginning to slightly ease. As the national unity government grapples with the huge task to restore growth in the Zimbabwean economy, it is important that these issues are borne in mind.

description: Macroscopic dark matter (macros) is a broad class of alternative candidates to particle dark matter. These candidates would transfer energy to matter primarily through elastic scattering. A sufficiently large macro passing through the atmosphere would produce a straight channel of ionized plasma. If the cross-section of the macro is $σ_x \gtrapprox 6 \times 10^{-9} cm^2$, then under atmospheric conditions conducive to lightning (eg. a thunderstorm) the plasma channel would be sufficient to seed a lightning strike with a single leader. This is entirely unlike ordinary bolt lightning in which a long sequence of hundreds or thousands of few-meter-long leaders are strung together. This macro-induced lightning would be extremely straight, and thus highly distinctive. Neither wind shear nor magnetohydrodynamic instabilities would markedly spoil its straightness. The only photographically documented case of a straight lightning bolt is probably not straight enough to have been macro-induced. We estimate the region of macro parameter space that could be probed by a search for straight lightning from the number of thunderstorms happening on Earth at any time. We also estimate the parameter space that can be probed by carefully monitoring Jupiter, e.g. using the Hubble Space Telescope. All code and data is available at https://github.com/cwru-pat/macro_lightning.

description: We present a geometric description of lepton flavor mixing and CP violation in matter by using the language of leptonic unitarity triangles. The exact analytical relations for both sides and inner angles are established between every unitarity triangle in vacuum and its effective counterpart in matter. The typical shape evolution of six triangles with the terrestrial matter density is illustrated for a realistic long-baseline neutrino oscillation experiment.

description: A new experimental setup for dual ion microbeam irradiation and analysis of materials has been designed andcommissioned at the Ruđer Boˇskovi´c Institute (RBI). Ion beams in the MeV energy range are provided by twotandem accelerators, a 1.0 MV Tandetron and a 6.0 MV EN tandem Van de Graaff. The dual microprobe endstation is primarily dedicated for the performance of experiments where one ion microbeam is used for theirradiation, while the other ion microbeam is used for the analysis or ‘probing’ the in-situ changes induced duringthe target irradiation. Likewise, both microbeams can be also used independently, for experiments involvingeither ion beam characterization or ion beam irradiation techniques. The ion beam from the small tandemaccelerator is focused with a magnetic quadrupole triplet, which is more suitable for the high spatial resolutionwork with light ions. The ion beam from the larger accelerator is focused by an electrostatic quadruplet thatenables easier focusing of heavy ions. Details of the experimental setup, its capabilities in terms of ion beamirradiation and analysis techniques, as well as the first applications, are presented.

description: Neutron stars are efficient accelerators for bringing charges up to relativistic energies. We show that if positive ions are accelerated to ~1 PeV near the surface of a young neutron star (t_age < about 10^5 yr), protons interacting with the star's radiation field will produce beamed mu neutrinos with energies of ~50 TeV that could produce the brightest neutrino sources at these energies yet proposed. These neutrinos would be coincident with the radio beam, so that if the star is detected as a radio pulsar, the neutrino beam will sweep the Earth; the star would be a ``neutrino pulsar''. Looking for muon neutrino emission from young neutron stars will provide a valuable probe of the energetics of the neutron star magnetosphere.

description: The agricultural trade of the Sudan is expected to develop under the recent dramatic increase of world food prices. Sudan as one of the developing countries and as price taker on the world agricultural market has been affected greatly by the world price increase. This paper aims at studying the impact of the increasing world food prices on developments of the agricultural crops trade sector of Sudan. In this paper a multimarket model is used as the main tool to estimate the increase of the world food prices on the crop trade sector. Multi-market analysis is a tool for simulating the effects of agricultural price policies on outcomes considered of interest to policy makers. The model under consideration takes the normal specification of a standard partial equilibrium model; it is static and consists of a set of demand and supply equations for each commodity with the level of production and demand determined by factors including prices, income, and demand and supply-shift variables, in addition to various other assumptions about policies. Price transmission equations in the model establish links between the domestic price, the producer price (for producers of exportable products and of import-substitute products), the consumer price and the world market price. The model has been developed to calculate the impact of high food prices on the main economy variables including supply and demand of the major agricultural commodities. The scenario of high world food prices showed on one hand, an increase in farmers' incentives resulting in higher levels of production of agricultural commodities, on the other hand, consumers demand has decreased significantly, and trade indicators reflect a positive effect on the agricultural crop trade sector.
Investigation of the gouging abrasion resistance of materials in the mining industry

description: With increased budget constraints, innovative cost reduction methods are required to increase the profitability of today's mines. Abrasive wear reduction is a novel way to reduce costs and increase productivity. Specifically, gouging abrasion is making an increased contribution to abrasive wear losses in the oil sands industry. To assess material property requirements for mitigating this wear mechanism, jaw crusher gouging abrasion tests using a modified ASTM G81 procedure, have been carried out on a range of wear materials of interest for oil sands mining service. The method involves a comparison of the wear losses that occur for reference and selected test plates when a controlled amount of standard feed rock is comminuted in a laboratory jaw crusher. Among the classes of material evaluated have been Q&T plate steels, austenitic manganese steel, chromium and chromium molybdenum white irons as plain castings and in laminated forms and also chromium carbide and tungsten carbide overlaid wear plates. In addition, the initial stages of relationships are presented relating wear rates/factor, determined from the laboratory gouging abrasion test, to the quartz content of the abrasive material. Of all the materials tested, the laminated CrMo white consistently had the lowest wear factor (best gouging abrasion resistance). From the data produced by this work, the wear factor has a linear relationship with quartz, while the wear rate has a non-linear relationship.

description: The inverse structure functions of exit distances have been introduced as a novel diagnostic of turbulence which emphasizes the more laminar regions [1-4]. Using Taylor's frozen field hypothesis, we investigate the statistical properties of the exit distances of empirical 3D fully developed turbulence. We find that the probability density functions of exit distances at different velocity thresholds can be approximated by stretched exponentials with exponents varying with the velocity thresholds below a critical threshold. We show that the inverse structure functions exhibit clear extended self-similarity (ESS). The ESS exponents ξ(p,2) for small p (p<3.5) are well captured by the prediction of ξ(p,2)= p/2 obtained by assuming a universal distribution of the exit distances, while the observed deviations for large p's characterize the dependence of these distributions on the velocity thresholds. By applying a box-counting multifractal analysis of the natural measure constructed on the time series of exit distances, we demonstrate the existence of a genuine multifractality, endowed in addition with negative dimensions. Performing the same analysis of reshuffled time series with otherwise identical statistical properties for which multifractality is absent, we show that multifractality can be traced back to non-trivial dependence in the time series of exit times, suggesting a non-trivial organization of weakly-turbulent regions.

description: This paper addresses the problem of extending biodiversity conservation onto the communal lands of the Dwesa-Cwebe conservation area in the Eastern Cape, South Africa, by investigating the conditions that must be fulfilled for any success to be registered. These conditions were derived based on a qualitative survey conducted in the Nqabara Administrative Area. The study developed a conceptual framework to unravel the complex nature of the whole community conservation initiative. A focus group discussion was adopted as the data collection method; and the underlying factors that have contributed to the success of the initiative in the Nqabara Administrative Area were identified. Appropriate coding was assigned to each distinct and major factor for proper presentation of the results and observations were appropriately indicated to buffer the explanation of the achieved results. Recommendations were subsequently made for the Dwesa-Cwebe in terms of the decision-making instruments that demand critical consideration for any successful community biodiversity conservation to be achieved.

description: In this study, a novel fatty acid anhydride, named phalarisin 1, was successfully isolated from the ethyl acetate extract of Phalaris canariensis growing in Tunisia. The structural characterisation of the compound was achieved through various spectroscopic techniques including FT-IR, 1D and 2D-NMR spectroscopy, as well as acidic hydrolysis analyses. Remarkably, phalarisin exhibited potent antimicrobial properties against a range of pathogens including Micrococcus luteus, Bacillus subtilis, Fusarium oxysporum, and Fusarium phylophylum, with minimum inhibitory concentrations (MICs) ranging from 31.25 to 62.5 μg/mL. To grasp the antimicrobial potential of compound 1, molecular docking studies were performed and they furnished evidence indicating its ability to bind to proteins in bacteria and fungi that are pivotal for drug resistance.

description: In this paper, we examine the interactions of the top quarks with the $Z$ boson using the top quark pair production associated with neutrino pair ($t\bar{t}ν_{l}\bar{ν_{l}}$) at the LHC. In particular, potential constraints on the anomalous electroweak top-quark interactions are determined by considering two opposite-sign charged leptons, missing energy, and two b-tagged jets in the final state. The analysis is performed for a High Luminosity scenario of the LHC with an integrated luminosity of 3 ab$^{-1}$ of proton-proton collisions at a center-of-mass energy of 14 TeV. The $95\%$ confidence intervals are computed on the anomalous couplings considering a realistic detector simulation of an upgraded CMS detector including an average of 200 proton-proton interactions per bunch crossing. We find that the $t\bar{t}ν_{l}\bar{ν_{l}}$ channel can provide stringent bounds on the relevant Wilson coefficients and has the potential to serve as an additional handle beside the $t\bar{t}Z(Z\rightarrow l^{+}l^{-})$ and other channels to search for new physics.

The evaluation of haulage truck size effects on open pit mining
Creators: name: Bozorgebrahimi, Enayagollah
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the effects of equipment size selection on the economics of open pit mining. The work presented, illustrates the importance of considering equipment selection in the wider context of the entire mine. A methodology is presented for evaluating the various variables that are affected by equipment size, Equipment Size Sensitive Variables, (ESSV) that will aid the industry in making more effective equipment selection decisions. Initially, the thesis explores, classifies and discusses ESSVs. The importance of these variables and identified interrelationships are highlighted through mathematical and discrete event simulation methods. The research uses a set of case studies to show that the influence of the ESSV extends beyond the central mine production to encompass the mill, environment and community. The work reveals that some ESSVs such as reliability, tire cost and productivity are related to the current equipment technology therefore their effects are comparable for different mines, while other ESSVs are related to the mine and deposit characteristics, therefore their effects vary from mine to mine. Through the synthesis and enhancement of existing work this thesis develops techniques for the economic evaluation of equipment size and shows that the use of larger equipment has significant cost effects for some mines on other areas of the operation such as the mill. The techniques developed for ESSV evaluation include integration of orebody modeling, mine design, mill performance prediction, equipment production and maintenance costs. As typical of many research products the results show the need and importance for further work to enhance the knowledge developed about ESSV and the effect of scale on the mining industry.

description: We investigate the evolution of the networks of the cosmic strings in angled brane inflation. We show how they can be distinguished from the conventional ones. The cosmic strings in angled inflation are the daughter $D_{p-2}$ branes that are extended between the mother $D_p$ branes. In the effective action, the strings should have a moduli, since the endpoints of the $D_{p-2}$ branes can move freely on the $D_p$ branes. Then naturally the position of the $D_{p-2}$ branes, which corresponds to the moduli of the $(1+1)$-dimensional effective action, can vary along the cosmic strings. The variation of the moduli results in the peculiar $(1+1)$-dimensional kink configurations. The kinks are the monopoles on the strings. Therefore, the cosmic strings in angled inflation become necklaces. The loops of the necklaces can shrink to produce stable winding states, which look like coils. We show why the cosmological implications of the brane necklaces are important. We point out that the cosmic strings in generic models of brane inflation should become necklaces, depending on the structure of the compactified space and the effective potential of the model.

description: Purpose- The issue of export success and the ability to sustain oneself in international horticultural markets have become more critical in the recent global and economic downturn because of its significance to the economy and to actors in the horticultural export chain. The extent of success is even much critical for enterprises. Therefore this study establishes the factors which influence the intensity of export success which measures the extent of export success. Design- Primary data were collected from 52 managers and representatives of horticultural exporting firms through a semi-structured questionnaire. The tobit model was used to estimate the intensity of export success by horticultural enterprises in Ghana. Findings- The result indicates that, manager’s educational level, managers past experience, manager trained in export management, manager’s entrepreneurial orientation, presence of export department, product diversification and government support directly influences the intensity of export success. Export barriers and constraints in accessing working capital negatively influences intensity of export success. Practical implications- Personnel or personal development in terms of training in export management and build up of experience is important in the quest to improve the intensity of export success. Organizational reforms such as institution of export department and diversifying horticultural export products improves the intensity of export success. To improve the intensity of success, external factors such as working capital inaccessibility and trade barriers should be addressed by various stake holders. In all government and institutional interventions has been proved to be of the essence. Originality/value- Although various determinants of export performance or success have been established by researchers the factors that influence the intensity of export success is not known. This study therefore bridges this gab.

description: OH airglow is an important nocturnal emission of the Earth's mesopause region. As it is chemiluminescent radiation in a thin medium, the population distribution over the various roto-vibrational OH energy levels of the electronic ground state is not in local thermodynamic equilibrium (LTE). In order to better understand these non-LTE effects, we studied hundreds of OH lines in a high-quality mean spectrum based on observations with the high-resolution Ultraviolet and Visual Echelle Spectrograph at Cerro Paranal in Chile. Our derived populations cover vibrational levels between v = 3 and 9, rotational levels up to N = 24, and individual $Λ$-doublet components when resolved. As the reliability of these results critically depends on the Einstein-A coefficients used, we tested six different sets and found clear systematic errors in all of them, especially for Q-branch lines and individual $Λ$-doublet components. In order to minimise the deviations in the populations for the same upper level, we used the most promising coefficients from Brooke et al. (2016) and further improved them with an empirical correction approach. The resulting rotational level populations show a clear bimodality for each v, which is characterised by a probably fully thermalised cold component and a hot population with rotational temperatures between about 700 (v = 9) and 7,000 K (v = 4). The latter causes non-LTE contributions at low N, which can be estimated quite robustly based on the two-temperature model. The bimodality is also clearly indicated by the different dependence of the populations on changes in the effective height of the OH emission layer.

description: We consider the area functional defined by the integral of an Ornstein-Uhlenbeck process which starts from a given value and ends at the time it first reaches zero (its equilibrium level). Exact results are presented for the mean, variance, skewness and kurtosis of the underlying area probability distribution, together with the covariance and correlation between the area and the first passage time. Amongst other things, the analysis demonstrates that the area distribution is asymptotically normal in the weak noise limit, which stands in contrast to the first passage time distribution. Various applications are indicated.

description: We study the semiclassical behaviour of eigenfunctions of quantum systems with ergodic classical limit. By the quantum ergodicity theorem almost all of these eigenfunctions become equidistributed in a weak sense. We give a simple derivation of an upper bound of order $\abs{\ln\hbar}^{-1}$ on the rate of quantum ergodicity if the classical system is ergodic with a certain rate. In addition we obtain a similar bound on transition amplitudes if the classical system is weak mixing. Both results generalise previous ones by Zelditch. We then extend the results to some classes of quantised maps on the torus and obtain a logarithmic rate for perturbed cat-maps and a sharp algebraic rate for parabolic maps.

The influence of rotation in radiation driven winds from hot stars II. CAK topological analysis

description: The topological analysis from Bjorkman (1995) for the standard model that describes the winds from hot stars by Castor, Abbott & Klein (1975) has been extended to include the effect of stellar rotation and changes in the ionization of the wind. The differential equation for the momentum of the wind is non--linear and transcendental for the velocity gradient. Due to this non--linearity the number of solutions that this equation possess is not known. After a change of variables and the introduction of a new physically meaningless independent variable, we manage to replace the non--linear momentum differential equation by a system of differential equations where all the derivatives are {\it{explicitely}} given. We then use this system of equations to study the topology of the rotating--CAK model. For the particular case when the wind is frozen in ionization ($δ=0$) only one physical solution is found, the standard CAK solution, with a X--type singular point. For the more general case ($δ\neq 0$), besides the standard CAK singular point, we find a second singular point which is focal--type (or attractor). We find also, that the wind does not adopt the maximal mass--loss rate but almost the minimal.

description: In this paper, we suggest a novel method to aid lifelong learners to access relevant OER based learning content to master skills demanded on the labour market. Our software prototype 1) applies Text Classification and Text Mining methods on vacancy announcements to decompose jobs into meaningful skills components, which lifelong learners should target; and 2) creates a hybrid OER Recommender System to suggest personalized learning content for learners to progress towards their skill targets. For the first evaluation of this prototype we focused on two job areas: Data Scientist, and Mechanical Engineer. We applied our skill extractor approach and provided OER recommendations for learners targeting these jobs. We conducted in-depth, semi-structured interviews with 12 subject matter experts to learn how our prototype performs in terms of its objectives, logic, and contribution to learning. More than 150 recommendations were generated, and 76.9% of these recommendations were treated as useful by the interviewees. Interviews revealed that a personalized OER recommender system, based on skills demanded by labour market, has the potential to improve the learning experience of lifelong learners.

description: The 2019 GINA guidance incorporates the presence of T2 inflammation in severe asthma patients to determine eligibility for add-on biologic therapy, though little data exists to characterize this population. The objective of this manuscript is to conduct a descriptive analysis to characterize patients with severe asthma in emerging countries based on disease severity, patient exacerbation history, and T2 phenotype. A cross-sectional survey of physicians treating asthma patients ages 12 years and older was conducted in eight countries. Physicians characterized their severe asthma patients and reported data from their patients’ medical charts. Medical chart data was selected from the physicians’ six most recent asthma patients taking prescription medication. A total of 550 physicians completed the survey and filled out 3,300 patient record forms. A total of 876 patients have been characterized with uncontrolled severe asthma. Of the 420 patients with available EOS lab data, 40% are indicated with T2 inflammation (EOS ≥150/µL). Ninety-one percent of all patients with available IgE lab data (n = 498) had IgE 30 − 1500 IU/mL indicating allergy-driven asthma. Finally, chronic OCS use (as reported by physicians) was reported in 11% of patients. This research revealed that 65% of patients had at least one of three T2 inflammation comorbidities assessed: allergic rhinitis, chronic rhinosinusitis with nasal polyps, and atopic dermatitis. Discrepancies were observed between patients’ treatment regimens and GINA step reported, suggesting there may be room to improve understanding of asthma severity as defined per GINA guidelines as well as asthma control assessment in clinical practice.
