description: It is found that \feii emission contributes significantly to the optical and ultraviolet spectra of most active galactic nuclei. The origin of the optical/UV \feii emission is still a question open to debate. The variability of \feii would give clues to this origin. Using 7.5 yr spectroscopic monitoring data of one Palomer-Green (PG) quasi-stellar object (QSO), PG 1700+518, with strong optical \feii emission, we obtain the light curves of the continuum \lv, \feii, the broad component of \hb, and the narrow component of \hb by the spectral decomposition. Through the interpolation cross-correlation method, we calculate the time lags for light curves of \feii, the total \hb, the broad component of \hb, and the narrow component of \hb with respect to the continuum light curve. We find that the \feii time lag in PG1700+518 is $209^{+100}_{-147}$ days, and the \hb time lag cannot be determined. Assuming that \feii and \hb emission regions follow the virial relation between the time lag and the FWHM for the \hb and \feii emission lines, we can derive that the \hb time lag is $148^{+72}_{-104}$ days. The \hb time lag calculated from the empirical luminosity--size relation is 222 days, which is consistent with our measured \feii time lag. Considering the optical \feii contribution, PG 1700+518 shares the same characteristic on the spectral slope variability as other 15 PG QSOs in our previous work, i.e., harder spectrum during brighter phase.

description: A heavy-mass electron state is realized in a doped valence bond solid (Ti1-xVx)2O3. In this system, itinerant holes mediate the mainly ferromagnetic RKKY interaction between the localized magnetic moments and become readily spin-polarized under a magnetic field, while showing large negative magnetoresistance. In spite of the ferromagnetic interaction among the carriers, their effective mass is found to be 1 or 2 orders of magnitude larger than that of usual doped semiconductors. Such strong mass renormalization is ascribable to the polaron formation on the Ti-dimer, where the spin-singlet state is originally formed. Doping dependence of the electronic specific-heat coefficient implies that the dimeric lattice fluctuation or softening is responsible for the enhanced electron-phonon interaction.

description: The study assessed the agricultural marketing extension services’ needs of root and tuber crop farmers in Abia State , Nigeria . It describe d the socio economic characteristics of root and tuber crop farmers and identified the marketing extension services’ needs of root and tuber crop farmers in the state ; it ascertained the marketing measures through which farmers’ needs can be met . It employed public opinion survey using a structured questionnaire as instrument for data collect ion. It used a multistage sampling technique to select a sample of three hundred and eighty seven ( farmers . Descriptive analysis was adopted in analyzing the data collected. The findings showed that farmers were constantly in need of updated marketing extension services which include cooperatives ( x ̅ = 2.49), credit (x ̅ = 2.47), information (x ̅ = 2.77), market linkage (x ̅ = 2.91), storage ((x ̅ = 2.97), processing ((x ̅ = 2.86),, transportation ((x ̅ = 2.63),, programme to expand consumption((x ̅ = 2.68) and grading and standardization services (x ̅ = 2.67). Therefore, for extension workers to really assist farmers in this regard, it is important to assess from the farmer ‘s perspective the areas in which assistance is needed for root and tuber produce marketing . This is because program me s and services can be effective only when they meet real needs. It was recommended that organizations and agencies providing marketing extension services (ADPs, Research institutes, Universities, NGOs etc) should do so in accordance with famers’ needs. Governments should develop, support and promote training in marketing skills and services for farmers in the study area.
Generalization of radiative jet energy loss to non-zero magnetic mass

description: Reliable predictions for jet quenching in ultra-relativistic heavy ion collisions require accurate computation of radiative energy loss. With this goal, an energy loss formalism in a realistic finite size dynamical QCD medium was recently developed. While this formalism assumes zero magnetic mass - in accordance with the one-loop perturbative calculations - different non-perturbative approaches report a non-zero magnetic mass at RHIC and LHC. We here generalize the energy loss to consistently include a possibility for existence of non-zero magnetic screening. We also present how the inclusion of finite magnetic mass changes the energy loss results. Our analysis indicates a fundamental constraint on magnetic to electric mass ratio.

description: Quantum cosmology is usually studied quantizing symmetry-reduced variables. Is it possible, instead, to define quantum cosmology starting from the full quantum gravity theory? In Loop Quantum Gravity (LQG), it is possible to cut the degrees of freedom in a suitable way, in order to define a cosmological model. Such a model provides a tool for describing general fluctuations of the quantum geometry at the bounce that replaces the initial singularity. I focus on its simplest version, a "dipole" formed by two tetrahedra. This has been shown to describe a universe with anisotropic and inhomogenous degrees of freedom. Its dynamics can be given using the spinfoam formalism. I briefly review the present state of this approach.

description: In an attempt to achieve sustainable forest management, Nigeria has developed two streams of forest policies, with the latter National Forest Policy 2006, being a reviewed version of the former National Forest Policy 1988, as observed during desk investigation. The antecedents, starting from the colonial era to the global International Forest Regimes, which were based on sustain able development principles, contributed to the spate of forestry development in Nigeria. However, the challenges of forestry development still remain, calling for greater in depth into some aspects of forest policy development that will, amongst others, encourage meaningful forestry research, address poverty alleviation and food security, noting the gamut of non timber forest products available for development from the Nigerian forests. This invariably will be achieved with greater participation in forestry development including the vulnerable groups. In addition, it is pertinent to state that more robust national forest policies can be achieved through periodic reviews and should therefore be ensured.

description: Information on macronutrient uptake and nutrient use efficiency (NUE) of cassava genotypes under different planting dates is limited. The aims of this study were 1) to investigate the responses of cassava genotypes to planting dates for nutrient uptake and NUE and 2) to identify the superior genotypes based on these traits. Three cassava genotypes (Kasetsart 50 (KU50), Rayong 11 (RY11) and CMR38-125-77) were planted in a randomized complete block design with four replications at four planting dates (20-Apr, 30-Jun, 5-Oct and 15-Dec 2016) and harvested at 12 months after planting (MAP). Planting cassava on 20-Apr and 15-Dec produced the highest total crop nutrient uptake and nutrient uptake for storage roots. Whereas planting cassava on 5-Oct and 15-Dec with higher solar radiation, temperature, relative humidity and longer photoperiod during canopy establishment until high carbohydrates translocation and with lower temperature and shorter photoperiod during a dormancy period resulted in greater NUE for biomass and storage roots and nutrient harvest index for all genotypes and most elements. CMR38-125-77 and KU50 showed good performance in terms of total nutrient uptake across planting dates (1.45–38.31 g plant−1) for most elements. CMR38-125-77 seems to be the best genotype on the basis of high storage root dry weight, high NUE for both biomass (90.1–1,594.6) and storage roots (39.9–927.1) and nutrient harvest index (0.14–0.58) for almost all planting dates, except in planting date 20-Apr in which RY11 was the highest for these traits. The genotype identified is useful as parental source for further breeding programs to improve genotypes with high NUE and high storage root yield.

description: If I have done my job, the problems which are outlined in this book of poems will resist the type of abstraction required in this space. After all, the first problem any poet must engage is how to navigate the necessary fluctuations between abstract statements and concrete images. For this book, there are two conflicting desires which are always in flux: the desire for a world of things and the desire for a world of ideas. So it could be said that the poems in this book are problems themselves, generated by the larger problem inherent in trying to map the boundary that these two conflicting desires create. Of course, this is a problem for which all poets are grateful. It presents for us the unresolvable paradox that keeps us writing, a paradox which is re-stated in its own way by the title of this book. How can graces be familiar? Can they be found in the everyday occurrences of our lives, and if they can be found there, does it serve us better to embrace them or to renounce them? These problems are finally (and fortunately) unresolvable. These poems, if I have done my job, will situate themselves solely on the side of desire, insisting on the type of enjoyment that can only be obtained by leaving any conclusion to the reader.
Ignition column depths of helium-rich thermonuclear bursts from 4U 1728-34

description: We analysed thermonuclear (type-I) X-ray bursts observed from the low-mass X-ray binary 4U1728-34 by RXTE, Chandra and INTEGRAL. We compared the variation in burst energy and recurrence times as a function of accretion rate with the predictions of a numerical ignition model including a treatment of the heating and cooling in the crust. We found that the measured burst ignition column depths are significantly below the theoretically predicted values, regardless of the assumed thermal structure of the neutron star interior. While it is possible that the accretion rate measured by Chandra is underestimated, due to additional persistent spectral components outside the sensitivity band, the required correction factor is typically 3.6 and as high as 6, which is implausible. Furthermore, such underestimation is even more unlikely for RXTE and INTEGRAL, which have much broader bandpasses. Possible explanations for the observed discrepancy include shear-triggered mixing of the accreted helium to larger column depths, resulting in earlier ignition, or the fractional covering of the accreted fuel on the neutron star surface.

description: The study analyzed the credit demand by small holder farmers and was carried out in Bende L.G.A of Abia State , South Eastern Nigeria . A multi stage sampling procedure was used for the study in the selection of 90 smallholder farmers. Data were collected using structured questionnaire. Descriptive statistical tools, multiple regression and Probit models were employed in the data analysis. The result shows that the mean age of the respondents was 43.5 years 62.16% were female and majority (54.39%) were married. Meanwhile, 48.84% had no formal education with mean household size of 6.3 and did not belong to any social group. The result on volume of credit demanded showed that majority applied for loan within ₦51,000 100,000. Regression results of factors affecting volume of credit demanded showed that the coefficient for age, educational level, household size, farming experience, interest rate, loan transaction cost and annual income were all significant at 1%, 5%, 1%, 1%, 5%, 1%, and 5% respectively. The Probit regression result shows that increasing household size (1%), profit gain from loan (1%), and having multiple income sources (1%) all affect the farmer’s capacity to repay borrowed funds. Some of the problems encountered by small holder farmers in accessing credit from formal and informal sources include, high interest rate, short repayment time, spending a lot of time before getting the credit, inadequate collateral, lack of banks in the rural areas and complex bank procedure. The study therefore recommends that the farmers should be enlightened about the existence of formal agricultural credits and ways to access them. Measures should be put in place to monitor, check and reduce the misappropriation of agricultural credit by beneficiaries. Lastly, the problem of delay in disbursement of loans/credit to farmers should be properly addressed.

description: Financial technology (Fintech) is changing the world of finance for consumers in a variety of ways. Leveraging on digital tools like mobile phones, internet, smart cards, POS devices, etc., business models have experienced remarkable transformations. These transformations have practical impacts on different sectors of the economy; agriculture inclusive. This paper is a review of recent literature on digital innovations and their associated risks relative to the agro-entrepreneur. It noted that Digital Financial Services (DFS), also known as Mobile Financial Services (MFS) have positive implications for financial inclusion, agricultural value chain financing, and women empowerment among other things. However, in Nigeria these positive implications have not been felt by the majority of the masses. It is still on record that about 40 percent of the adult population in this country is financially excluded despite the many efforts of the apex bank to achieve financial inclusion. There is no gain saying the fact that majority of this financially excluded population are rural dwellers and as such are majorly engaged with farming and other agricultural activities. Again, findings indicate that there is no context sensitive package that can deliver finance to agro-entrepreneurs in a disruptive way as seen in Kenya, Uganda and Ghana. This paper will serve as a policy instrument to the government, private investors, Development Finance Institutions, DFIs, MNOs, fintech companies, researchers, and policy makers. It is a call for a collaborative consideration on how to capture the many potential benefits of DFS in agriculture, not forgetting its associated risks, in a bid to create a trade competitive agribusiness ecosystem.
Modelling exciton dynamics in light-harvesting molecules
Creators: name: Ruocco, Leonard
Publisher: name: University of British Columbia
Year: 2020

description: I investigate the dynamics of multi-state central systems coupled bilinearly to an external oscillator bath within the noninteracting-blip approximation. I focus on both a 3-site configuration, as well as a 2-site model for the central systems of interest. The 2-site model, dubbed the dual-coupling spin-boson (DCSB) model, includes both diagonal and non-diagonal system-bath couplings, whereas the 3-site model considers only diagonal couplings. The bath spectral densities considered in this work include both Ohmic and super-Ohmic forms, as well as single optical phonon peaks. This work is motivated by the recent observance of long-lived quantum coherence effects in the photosynthetic organism known as the Fenna-Matthews-Olson (FMO) complex. The models investigated in this thesis are applied to this system in an attempt to explain its remarkably efficient exciton transfer mechanism, as well as to shed light on the functionality of coherence. The DCSB model is shown to reproduce the rapid exciton transfer times as well as the relatively long coherence times observed in the FMO complex. The non-diagonal system-bath coupling is shown to play a crucial role in this process. This can be attributed to the inelastic phonon-assisted tunnelling (IPAT) mechanism arising from the presence of significant non-diagonal system-bath interactions. Conversely, the 3-site model predicts rapid but incoherent exciton transfer. This can be attributed to the presence of a resonant state in the 3-site architecture, resulting in a relatively slow exciton transfer mode in the system. Therefore efficient exciton transfer requires a careful configuration of the chromophore energy landscape to avoid a resonant 3-site-V configuration. Furthermore, I conclude that coherence effects arising from excitons delocalised across multiple chromophores, promotes IPAT processes arising from non-diagonal system-bath couplings, producing rapid exciton transfer between chromophores. This offers a potential explanation as to the functional role that coherence plays in the energy transfer mechanism of photosynthesis.

description: We report the development of a compact turn-key module that boosts the resolution in quasi-elastic neutron scattering by several orders of magnitude down to the low sub-micro-eV range. It is based on a pair of neutron resonance spin flippers that generate a well defined temporal intensity modulation, also known as MIEZE (Modulation of IntEnsity by Zero Effort). The module may be used under versatile conditions, in particular in applied magnetic fields and for depolarising and incoherently scattering samples. We demonstrate the power of MIEZE in studies of the helimagnetic order in MnSi under applied magnetic fields.

description: Random matrix model for the Nakagami-q (Hoyt) fading in multiple-input multiple-output (MIMO) communication channels with arbitrary number of transmitting and receiving antennas is considered. The joint probability density for the eigenvalues of H†H (or HH†), where H is the channel matrix, is shown to correspond to the Laguerre crossover ensemble of random matrices and is given in terms of a Pfaffian. Exact expression for the marginal density of eigenvalues is obtained as a series consisting of associated Laguerre polynomials. This is used to study the effect of fading on the Shannon channel capacity. Exact expressions for higher order density correlation functions are also given which can be used to study the distribution of channel capacity.

description: The study analyzed the profitability and effects of farm resources on broiler output in Nwangele Local Government Area of Imo State, South East Nigeria. A total of fifty broiler farmers were randomly selected from a list of 120 poultry farmers registered with Imo State Agricultural Development Programme Office. Data were collected using a set of structured questionnaire. Analytical tools used were descriptive statistical tools, net farm income and multiple regression models. Out of the three functional forms tried, double log model emerged as the lead equation because results indicated that 84% of the farmers used deep litter housing system in broiler production and 92% of them stocked 1000 birds or less in their farms. On the average, a farmer spent N289, 051.67 on purchase of variable inputs, out of which, cost of poultry feeds was N142, 405.34. A net income of N442,5281.36K was realized per annum which implied that broiler production is a profitable business. Multiple regression result indicated that stock size was positive and significant at 1% level while quantity of feeds used was significant at 5% but showed negative influence on broiler production. It is recommended that farmers should increase the number of day old chicks and reduce labour and quantity of feeds used in broiler production

description: In the framework of a semi-classical expansion for quantum chromodynamics in the instanton liquid background, the correlation function of the $0^{++}$ scalar glueball current is given. Besides the pure classical and quantum contributions, the contributions arising from the interactions between the classical instanton fields and quantum gluons are taken into account as well. Instead of the usual zero-width approximation for the resonance, the Brite-Wigner form for the spectral function of the finite-width resonance is adopted. The family of the Laplace sum rules for the scalar glueball in quantum chromodynamics with and without light quarks are studed. A consistency between the subtracted and unsubtracted sum rules are very well justified, and the values of the mass, decay width, and the coupling to the corresponding current for the $0^{++}$ resonance in which the glueball fraction is dominant, are obtained.

Integrated strategic, tactical and operational planning of forest-based biomass supply chains for energy and fuel production : a hybrid optimization simulation approach
Creators: name: Akhtari, Shaghaygh
Publisher: name: University of British Columbia
Year: 2019

description: Biomass has emerged as an attractive renewable source of energy to shift away from fossil fuels. However, the high cost of biomass feedstock and variations, such as those in biomass supply and demand, impact the competitiveness of biomass and restrict bioenergy and biofuel developments. Therefore, supply chain planning is essential in improving the efficiency of biomass supply chains. In the literature, supply chain planning often has been carried out at strategic, tactical, and operational levels hierarchically by developing distinct models. Hierarchical planning may result in inconsistent and even infeasible solutions of higher planning levels at the lower levels because the details and variations at the lower levels are not considered at the higher levels. Hence, integrating the three different planning levels, while capturing the variations at the lower planning levels, could assure that plans from higher levels (e.g. strategic) are attainable at lower planning levels (tactical and operational). However, an integrated optimization model could require an enormous computational effort for solving. Therefore, proper solution approaches that can overcome this problem should be used. The main goal of this dissertation is to develop an integrated strategic, tactical, and operational planning model considering variations and details of lower planning levels, and employ a suitable solution approach to solve it. Herein, first, an optimization model that integrates the strategic and tactical decisions of forest-based biomass supply chains is developed to optimize the design of the supply chain considering variations at the tactical level. Then, three common decision rules, representing optimistic, moderate pessimistic, and pessimistic perspectives, are used to optimize the design of the supply chain considering the decision maker’s perspective towards risk. Next, a discrete event simulation model is developed to incorporate the operational level variations and its aspects. Finally, a hybrid scheme is proposed in which a linkage between the optimization and the simulation models is constructed to integrate different planning levels while incorporating variations at tactical and operational levels. The hybrid model is applied to a case study. The results of this research indicate that ignoring the tactical and operational level variations could result in sub-optimal and even infeasible solutions.

description: We consider the conductance distributions in chaotic mesoscopic cavities for all three invariant classes of random matrices for the arbitrary number of channels N1, N2 in the connecting leads. We show that the Laplace transforms of the distributions can be expressed in terms of determinants in the unitary case and Pfaffians in the orthogonal and symplectic cases. The inverse Laplace transforms then give the exact distributions. This formalism is particularly useful for small values of N = min (N1, N2), and thus is of direct experimental relevance. We also obtain the conductance distributions for orthogonal-unitary and symplectic-unitary crossover ensembles.

description: A minimally invasive approach to radical prostatectomy offers improved ambulation and discharge times. Postoperative pain control is one of the key factors that facilitates rapid recovery. With the aim to assure adequate analgesia and minimize the use of opioids, application of truncal nerve blocks has been proposed in a number of endoscopic procedures. The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of bilateral posterior quadratus lumborum block (pQLB) in alleviating pain and reducing postoperative opioid demand in patients following endoscopic extraperitoneal and laparoscopic prostatectomy. We enrolled 50 patients who were diagnosed with prostate cancer and scheduled for prostatectomy. They were randomized to receive preoperative, ultrasound-guided pQLB with the use of either 30 ml of 0.375 % ropivacaine (ropivacaine group) or 30 ml of 0.9 % NaCl (placebo group). Our primary endpoint was opioid consumption in the first 24 hours after surgery. Secondary endpoints were pain intensity at predefined timepoints and the incidence of nausea and vomiting and pruritus. No differences were detected between the ropivacaine and placebo groups in intravenous oxycodone consumption during the first 24 hours after surgery. Similarly, there were no differences in pain intensity at any of the timepoints assessed. The rate of nausea and vomiting was equal in both groups and pruritus was not observed. Application of bilateral pQLB does not reduce opioid consumption after minimally invasive prostatectomy.

description: The optical conductivities of graphene layers are strongly dependent on their stacking orders. Our first-principle calculations show that while the optical conductivities of single layer graphene (SLG) and bilayer graphene (BLG) with Bernal stacking are almost frequency independent in the visible region, the optical conductivity of twisted bilayer graphene (TBG) is frequency dependent, giving rise to additional absorption features due to the band folding effect. Experimentally, we obtain from contrast spectra the optical conductivity profiles of BLG with different stacking geometries. Some TBG samples show additional features in their conductivity spectra in full agreement with our calculation results, while a few samples give universal conductivity values similar to that of SLG. We propose those variations of optical conductivity spectra of TBG samples originate from the difference between the commensurate and incommensurate stackings. Our results reveal that the optical conductivity measurements of graphene layers indeed provide an efficient way to select graphene films with desirable electronic and optical properties, which would great help the future application of those large scale misoriented graphene films in photonic devices.

description: Ratchet dynamics of topological solitons of the forced and damped discrete double sine-Gordon system are studied. Directed transport occurring both in regular and in chaotic regions of the phase space and its dependence on damping, amplitude and frequency of the driving, asymmetry parameter, coupling constant, has been extensively investigated. We show that the passage from ratchet phase-locked regime to chaotic ratchets occurs via a period doubling route to chaos and that, quite surprisingly, pinned states can exist inside phase-locking and chaotic transport regions for intermediate values of the coupling constant. The possibility to control chaotic discrete soliton ratchets by means of both small subharmonic signals and more general periodic drivings, has also been investigated.

description: In this paper, a comparative analysis of regulatory documents, namely SNiP 12-03-2001, SNiP 12-03-2002, as well as the Rules on labor protection in construcÂ¬tion, on the structure and on the impact on the dynamics of industrial injuries is carÂ¬ried out. As part of this study, the dynamics of industrial injuries in the construction industry are considered on the basis of statistical data from 2000 to 2017. The paper also proposes a number of changes that can lead to a decrease in the number of acciÂ¬dents when they are introduced into legislative acts.
