description: When a space in which Christoffel symbols of the second kind are symmetrical in lower indices exists, it makes for a supplement to the standard procedure when a 2D surface is normally induced from the geometry of the surrounding 3D space in which the surface is embedded. There it appears appropriate to use a scheme for straightforward permutation of indices of Gkij, when such a space would make this transformation possible, so as to obtain the components of the 2D Riemann-Christoffel tensor (here expressed in geodetic coordinates for an ellipsoid of revolution, of use in geophysics). By applying my scheme I find the corresponding indices in 2D and 3D supplement-spaces, and I compute components of the Riemann-Christoffel tensor. By operating over the elements of the projections alone, the all-known value of 1/MN for the Gaussian curvature on an ellipsoid of revolution is obtained. To further validate my scheme, I show that in such a 3D space the tangent vector to a PHI-curve for LAM=const1 would be parallel to a tangent vector to a PHI-curve for LAM=const2 on the surface of an ellipsoid of revolution. Surfaces parameterized by Gauss surface normal coordinates, such as the Earth, now can have the Riemann-Christopher curvature tensor computed in a straightforward fashion for the topographic surface hel(PHIel, LAMel) of the Earth, given Christoffel symbols for such a representation in terms of orthonormal functions on the ellipsoid of revolution.

description: The effects of the finite top quark width in the top pair production cross section close to the threshold are discussed in this talk. We introduce a $t\bar{t}$ cross section with a cut on the invariant masses of the top and antitop that can be calculated theoretically with effective field theory (EFT) methods. The matching procedure to implement the physical phase-space boundaries in the NRQCD framework (``phase-space matching'') is briefly outlined.

description: We discuss the chiral phase transition in hot and dense QCD with three light flavors. Inspired by the well known fact that the U_A(1) anomaly could induce first order phase transitions, we study the effect of the possible restoration of the U_A(1) symmetry at finite density. In particular, we explore the link between the U_A(1) restoration and the recent lattice QCD results of de Forcrand and Philipsen, in which the first order phase transition region near zero chemical potential (mu) shrinks in the quark mass and mu space when mu is increased. Starting from the Ginzburg-Landau theory for general discussions, we then use the Nambu--Jona-Lasinio model for quantitative studies. With the partial U_A(1) restoration modeled by the density dependent 't Hooft interaction, we fit the shrinking of the critical surface found in de Forcrand and Philipsen's lattice calculation at low mu. At higher mu, the critical surface might shrink or expand, depending on the scenarios. This raises the possibility that despite the shrinking of the critical surface at lower mu, the QCD critical end point might still exist due to the expansion at higher mu. In this case, very high precision lattice data will be needed to detect the back-bending of the critical surface with the currently available analytic continuation or Taylor expansion approaches. Lattice computations could, however, test whether the U_A(1) restoration is responsible for the shrinking of the critical surface by computing eta' mass or the topological susceptibility at small mu.

description: Antimicrobial nanocoatings may be a means of preventing nosocomial infections, which account for significant morbidity and mortality. The role of hospital sink traps in these infections is also increasingly appreciated. We describe the preparation, material characterization and antibacterial activity of a pipe cement-based silver nanocoating applied to unplasticized polyvinyl chloride, a material widely used in wastewater plumbing. Three-dimensional surface topography imaging and scanning electron microscopy showed increased roughness in all surface finishes versus control, with grinding producing the roughest surfaces. Silver stability within nanocoatings was >99.89% in deionized water and bacteriological media seeded with bacteria. The nanocoating exhibited potent antibiofilm (99.82–100% inhibition) and antiplanktonic (99.59–99.99% killing) activity against three representative bacterial species and a microbial community recovered from hospital sink traps. Hospital sink trap microbiota were characterized by sequencing the 16S rRNA gene, revealing the presence of opportunistic pathogens from genera including Pseudomonas, Enterobacter and Clostridioides. In a benchtop model sink trap system, nanocoating antibiofilm activity against this community remained significant after 11 days but waned following 25 days. Silver nanocoated disks in real-world sink traps in two university buildings had a limited antibiofilm effect, even though in vitro experiments using microbial communities recovered from the same traps demonstrated that the nanocoating was effective, reducing biofilm formation by >99.6% and killing >98% of planktonic bacteria. We propose that conditioning films forming in the complex conditions of real-world sink traps negatively impact nanocoating performance, which may have wider relevance to development of antimicrobial nanocoatings that are not tested in the real-world.

description: We propose a quantum storage scheme independent of the current time-control schemes, and study a "quantum data bus" (transmission line resonator) in a hybrid system consisting of a circuit QED system integrated with a cold molecular ensemble. Here, an effective interaction between charge qubit and molecule is mediated by the off-resonate field in the data bus. Correspondingly, the charge state can be mapped into the collective quasi-spin state of the molecular ensemble via the standard dark state based adiabatic manipulation.

After introducing some new variables to explicitly express potentials, the super AKNS system is decomposed into two compatible finite-dimensional super systems (x-part and $t_n$-part). Furthermore, we show that the obtained super systems are integrable super Hamiltonian systems in supersymmetry manifold $\mathbb{R}^{4N+2|2N+2}$.

Conflict resolution in the family : PET skills acquisition in parent/adolescent dyads
Creators: name: Wood, CD
Publisher: name: University Of Tasmania
Year: 2023

description: Parent Effectiveness Training (PET) (Gordon, 1975) is a practical course teaching communication skills to parents, particularly listening, assertiveness and conflict resolution. Youth Effectiveness Training (YET) (Hall & Zener, 1981) teaches the same skills to teenagers from their own viewpoint. Both are aimed at improving the quality of family life, and at prevention of serious problems. Research into PET has been largely concerned with attitudinal change, and there is an overwhelming need for investigation of behavioural outcomes. The present study attempted a behavioural measure of specific PET skills, utilising a three-minute video-recorded roleplay of a standardised conflict interaction between parent and adolescent. There were 13 parent/teenager dyads in the experimental group, and 11 similar pairs, matched as closely as possible, in the control group. The videoed interactions were put onto a single tape in random order and assessed \blind\" by three skilled independent raters using bi-polar visual analog scales especially constructed to measure listening and confrontation skills and conflict resolution. Results showed that the parents improved significantly in conflict resolution and in confrontation skills as compared with the control group. On listening skiills they improved considerably more than the control group but the difference was not great enough to be statistically significant. The teenagers in the experimental group improved significantly more than those in the control group in conflict resolution. Their gains in listening and confrontation skills were also greater than those of the control group but the differences were not large enough to be regarded as statistically significant. Standard questionnaires constructed to measure (a) attitudinal changes in parent-child relationships as an outcome of parent education (Parent Attitude Survey Hereford1963) (b) changes in self-concept (Self Esteem Inventory Coopersmith 1967) following the course and (c) changes relating to expressed behaviour (FIRO-B Schutz 1967) were administered as part of the overall assessment but no significant differences were found between the groups. However the study showed that parent/adolescent dyads can change their interactions in a positive way using skills that can be spontaneously applied."
Effectiveness of patient drug record plans : An evaluation
Creators: name: Waller, Ronald Henry
Publisher: name: University of British Columbia
Year: 2011

description: An evaluation was undertaken to determine the effectiveness of patient record plans which had been in use in two community pharmacies for periods of 6 and 9 years. A retrospective study of potential tetracycline interactions demonstrated that, numerically, the nonprescription drugs represented the greatest potential danger. Although in the past, non-prescription medications were not routinely recorded, it is concluded that both prescribed and non-prescribed drugs should be entered on patient record charts and screened for potential interactions. The routine recording and screening of patient allergies and disease states on the patient record plan was shown to be of value in several instances in one pharmacy. A comparison of drug sensitivities 'flagged' on pharmacy records and physician's records showed that the pharmacist often had on record more allergies than did the physician. Using the patient record plan to determine the theoretical time of the last dose of an antibiotic, two surveys were undertaken to determine if a written reinforcement of verbal instructions and patient involvement in a follow-up interview could help improve self-administration habits in ambulatory patients. It was found that more patients did, in fact, follow, their dosage regimen and fewer patients discontinued their course of therapy without justification. Seventeen steps were defined in a dispensing procedure used in one of the pharmacies operating with a patient record plan. These could be further divided into those functions which could be performed by a non-professional assistant and those which were to be done only by a pharmacist. The time required for the individual pharmacist to perform all 17 steps was compared to the time required for a (pharmacist and non-professional assistant) team to do the same functions. Pharmacist time per prescription appeared to be reduced 40 to 50% by the team approach.

description: Over the last 10 years, the number of publicly traded companies that have had to restate financial results has risen dramatically. Regardless of whether the restatements stemmed from the aggressive application of accounting standards or the need to correct intentional distortion of results by management, the outcome was often the same: a sudden and significant loss of shareholder value. In many cases, the restatement process led to significant turmoil within the company, including investigations by financial regulators, the resignation of chief executives and other senior officials, wide-scale restructuring and employee layoffs, and lawsuits against the board of directors, auditors, and other involved parties. The effects on the organization were often felt for years, taking a significant financial and reputational toll. This case examines five categories of financial restatements, as defined by Charles W. Mulford and Eugene E. Comiskey: recognizing premature or fictitious revenue, aggressive capitalization and extended amortization of expenses, misreporting assets and liabilities, other income statement items, and problems with cash flow reporting. Examples are provided for each category based on the events at Catalina Marketing, Krispy Kreme, Royal Dutch Shell, Royal Ahold, Nortel Networks, and Parmalat.

description: Air pollution is an environmental factor associated with an increased risk of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s, characterized by decreased cognitive abilities and memory. The limited models of sporadic Alzheimer’s disease fail to replicate all pathological hallmarks of the disease, making it challenging to uncover potential environmental causes. Environmentally driven models of Alzheimer’s disease are thus timely and necessary. We used live-cell confocal fluorescent imaging combined with high-resolution stimulated emission depletion (STED) microscopy to follow the response of retinoic acid-differentiated human neuroblastoma SH-SY5Y cells to nanomaterial exposure. Here, we report that exposure of the cells to some particulate matter constituents reproduces a neurodegenerative phenotype, including extracellular amyloid beta-containing plaques and decreased neurite length. Consistent with the existing in vivo research, we observed detrimental effects, specifically a substantial reduction in neurite length and formation of amyloid beta plaques, after exposure to iron oxide and diesel exhaust particles. Conversely, after exposure to engineered cerium oxide nanoparticles, the lengths of neurites were maintained, and almost no extracellular amyloid beta plaques were formed. Although the exact mechanism behind this effect remains to be explained, the retinoic acid differentiated SH-SY5Y cell in vitro model could serve as an alternative, environmentally driven model of neurodegenerative diseases, including Alzheimer’s disease.
title: Women & Elegy: Towards Destructuring Economies of Loss and Reconfiguring Elegiac Tradition.
Creators: name: Perry, Eleanor
Publisher: name: University of Kent
Year: 2016

description: This thesis investigates—and seeks to address—the excision, marginalization and sequestering of female work within the elegiac tradition. Beginning with an analysis of key texts in elegy scholarship from the last thirty years, and the ways in which they participate in—and perpetuate—this marginalization, the thesis develops a transhistorical sketch of the elegiac tradition. This sketch examines the evolution of elegy as a genre, outlining Western cultural frameworks for understanding mourning, and historical perspectives which consider grief expression as a threat requiring constraint; as well as significant shifts in medical, theological and philosophical conceptions of melancholy—in order to delineate how and why women’s elegiac work has been marginalized within the traditional canon. This includes an in-depth critique and analysis of Freud’s 1917 paper ‘Mourning and Melancholia,’ upon which much of current elegy scholarship depends, approaching both the gendered binary within Freud’s model, and the framework of economics which he uses to illustrate this model. This analysis is then extended through the post-Freudian work of Irigaray and Kristeva, as well as subsequent feminist thinkers, in order to question how we might begin to rectify the marginalization of female work without effacing the contexts within which it has been marginalized. These ideas are then extended and developed through the close reading of contemporary elegies by Susan Howe, Kristin Prevallet, Anne Carson, Maggie O’Sullivan and Claudia Rankine, investigating, among other things, erasure; resistance to closure; error and failure; disruption of reading practices; lyric instability and possibilities of shared grief. The length of the critical section of the thesis and extensive use of footnotes have both been agreed with my supervisory team on account of the scope of the project, and the examples required to demonstrate its argument. The critical section is followed by a collection of poetry made up of four interrelated sequences. These sequences seek to continue the arguments raised in the thesis, and reflect on the research demonstrated therein, specifically interrogating master narratives such as language, myth and history, in order to question notions of lament and pastoral; exploring the limits of the lyric and the possibility of speaking with, rather than speaking for an other; and the poential for harm within processes of textual recovery and memorialization.

description: Spin-entanglement of two electrons occupying two spatial regions -- domains -- is expressed in a compact form in terms of spin-spin correlation functions. The power of the formalism is demonstrated on several examples ranging from generation of entanglement by scattering of two electrons to the entanglement of a pair of qubits represented by a double quantum dot coupled to leads. In the latter case the collapse of entanglement due to the Kondo effect is analyzed.

description: Plastic pollution has become a major environmental concern, and various plastic polymers are used daily. A study was conducted to examine the toxic effects of polyethylene terephthalate (PET) nanoplastics (NPLs) on Drosophila melanogaster. We have successfully synthesized PET NPLs and characterized using DLS, Zeta potential, TEM, HRTEM, SAED, XRD, FTIR, and Raman spectroscopy to gain crucial insights into the structure and properties. We fed PET NPLs to Drosophila to assess toxicity. ROS was quantified using DCFH-DA and NBT, and the nuclear degradation was checked by DAPI staining. Quantification of protein and activity of antioxidant enzymes like SOD, catalase depicted the adverse consequences of PET NPLs exposure. The dorsal side of the abdomens, eyes, and wings were also defective when phenotypically analyzed. These results substantiate the genotoxic and cytotoxic impact of nanoplastics. Notably, behavioral observations encompassing larval crawling and climbing of adults exhibit normal patterns, excluding the presence of neurotoxicity. Adult Drosophila showed decreased survivability, and fat accumulation enhanced body weight. These findings contribute to unraveling the intricate mechanisms underlying nanoplastic toxicity and emphasize its potential repercussions for organismal health and ecological equilibrium.

description: The energetic stability and electronic properties of hydrogenated silicon carbide nanowires (SiCNWs) with zinc blende (3C) and wurtzite (2H) structures are investigated using first-principles calculations within density functional theory and generalized gradient approximation. The [111]-orientated 3C-SiCNWs are energetically more stable than other kinds of NWs with similar size. All the NWs have direct band gaps except the 3C-SiCNWs orientating along [112] direction. The band gaps of these NWs decrease with the increase of wire size, due to the quantum-confinement effects. The direct-band-gap features can be kept for the 3C-SiCNWs orientating along [111] direction with diameters up to 2.8 nm. The superior stability and electronic structures of the [111]-orientated 3C-SiCNWs are in good agreement with the experimental results.

description: A novel brain-targeted and reactive oxygen species-activatable manganese dioxide containing nanoparticle system functionalized with anti-amyloid-β antibody (named aAβ-BTRA-NC) developed by our group has shown great promise as a highly selective magnetic resonance imaging (MRI) contrast agent for early detection and multitargeted disease-modifying treatment of Alzheimer’s disease (AD). To further evaluate the suitability of the formulation for future clinical application, we investigated the safety, biodistribution, and pharmacokinetic profile of aAβ-BTRA-NC in a transgenic TgCRND8 mouse AD model, wild type (WT) littermate, and CD-1 mice. Dose-ascending studies demonstrated that aAβ-BTRA-NC was well-tolerated by the animals up to 300 μmol Mn/kg body weight [b.w.], 3 times the efficacious dose for early AD detection without apparent adverse effects; Histopathological, hematological, and biochemical analyses indicated that a single dose of aAβ-BTRA-NC did not cause any toxicity in major organs. Immunotoxicity data showed that aAβ-BTRA-NC was safer than commercially available gadolinium-based MRI contrast agents at an equivalent dose of 100 μmol/kg b.w. of metal ions. Intravenously administered aAβ-BTRA-NC was taken up by main organs with the order of liver, kidneys, intestines, spleen, followed by other organs, and cleared after one day to one week post injection. Pharmacokinetic analysis indicated that the plasma concentration profile of aAβ-BTRA-NC followed a 2-compartmental model with faster clearance in the AD mice than in the WT mice. The results suggest that aAβ-BTRA-NC exhibits a strong safety profile as a nanotheranostic agent which warrants more robust preclinical development for future clinical applications.

We consider neutral atomic Fermi gases in a harmonic trap, the pairing being produced by a Feshbach resonance via a d-wave interaction channel. A Ginzburg-Landau (GL) functional is constructed which is symmetry constrained for five component order parameters (OP). We find OP textures in the cyclic phase and stability conditions for a non-Abelian fractional 1/3-vortex under rotation. It is proposed how to create the intriguing 1/3-vortex experimentally in atomic gases via optical means.

description: We present a sum-product formula for the classical Hall polynomial which is based on tableaux that have been introduced by T. Klein in 1969. In the formula, each summand corresponds to a Klein tableau, while the product is taken over the cardinalities of automorphism groups of short exact sequences which are derived from the tableau. For each such sequence, one can read off from the tableau the summands in an indecomposable decomposition, and the size of their homomorphism and automorphism groups. Klein tableaux are refinements of Littlewood-Richardson tableaux in the sense that each entry $\ell \geq 2$ carries a subscript $r$. We describe module theoretic and categorical properties shared by short exact sequences which have the same symbol $\ell_r$ in a given row in their Klein tableau. Moreover, we determine the interval in the Auslander-Reiten quiver in which indecomposable sequences of $p^n$-bounded groups which carry such a symbol occur.

description: Manipulation of sudden death of entanglement (ESD) of two qubits interacting with statistically uncorrelated thermal reservoirs is investigated. It is shown that for initially prepared X-states of the two qubits a simple (necessary and sufficient) criterion for ESD can be derived with the help of the Peres-Horodecki criterion. This criterion implies that, in contrast to the zero-temperature case, at finite temperature of at least one of the reservoirs all initially prepared two-qubit X-states exhibit ESD. General conditions are derived under which ESD can be hastened, delayed, or averted.

description: The developments of a multifunctional Agricultural Robot which will be capable of automating critical operations in agriculture including tilling, sowing seeds and irrigation of the farmland will be covered through this research paper. At the heart of the system is a microcontroller-an Arduino, which governs all actions of the robot. The robot would start the operation using a high-torque DC geared motor to till the soil efficiently so that it may be set as optimum before planting. Then, it would drop the seeds at uniform intervals and at the right time, switching on a computer-controlled sprinkler to cater for moisture needs for the germination of seedlings. The robot will have various sensors as a component of the smart feature of these robots. A Soil Moisture Sensor would evaluate the moisture content of the soil, and optimize watering intervals. The DHT11 Sensor senses the room temperature and humidity, assisting in monitoring the environment. The NPK sensor is for soil nutrient composition as it helps assess soil fertility and plan the appropriate strategy for fertilizing. Based on this, the IoT module allows remote operation of the robot by farmers by controlling the working of the robot from their mobile application or web platform. It will have a positive impact by reducing physical labor dramatically.

Isoperla rainiera

description: Isoperla rainiera Jewett (Figs. 13 a-d) Isoperla rainiera Jewett 1954. Holotype ♂, Washington, Pierce County, Mount Rainier National Park. Male. Aedeagus: sclerotized posterior process present; body of aedeagus with one small posterior lobe, one dorsal lobe, and one anterior lobe (Fig. 13a); sclerotized process length <0.5 mm, recurved, crescent shaped, apex broadly rounded with two lateral sharp hook-like projections directed anteriorly (Figs. 13 a-c). Abdominal terga 8-9, 9, 9-10: without stout spinulae or long stout setae. Posterolateral margins of at least abdominal segment 8 with scalelike setae clustered in brushes of several setae. Paraprocts: curved dorsally, length if straightened subequal to combined first and second cercal segments, tapering gradually to long sharp apices (Fig. 13c). Vesicle: pedunculate, length subequal to width, constricted near base with curved lateral margins, wider and rounded at apex (Fig. 13d). Isoperla rainiera shares several characters with species of the I. sordida complex (Table 1). It differs from these species in paraproct shape and aedeagal characters. The paraprocts taper gradually to sharp apices and the apex of the sclerotized process is crescent shaped. This species is not known from California, recorded from Oregon and Washington (Szczytko & Stewart 1979). Material Examined. WASHINGTON, Skamania Co., Tyee Spring, Meadow Creek Rd, 0.44 mi (0.7 km) N of NFD3065 & NFD30, 45.87568°N, 121.97095°W, 16/ VI /2011, 2♂, 10♀ (JBSC).

Studies on the cytoplasmic dna polymerases from the intestinal mucosa of rat
Creators: name: Waung, Lucille Yih-Lo
Publisher: name: University of British Columbia
Year: 2011

description: Significant DNA polymerase activity has been found in cytoplasmic preparations from rat intestinal mucosa. The present work involves a partial purification and a study of the general properties of this cytoplasmic enzyme activity. Crude cytoplasmic enzyme was prepared by high-speed centrifugation of the homogenate of washed mucosal scrapings. A strong inhibitor of DNA polymerase was sedimented by the high-speed centrifugation. The bulk of the enzyme activity was unadsorbed on DEAE-cellulose. However, a minor portion of the enzyme was adsorbed, and was eluted with 0.1 M KC1. When crude cytoplasmic enzyme was chromatographed by gel-filtration on Sephadex G-150, a single peak of DNA polymerase activity was detected. By the use of protein markers with known molecular parameters, the molecular weight of the DNA polymerase fraction was estimated to be 101,000. The enzyme required the presence of a DNA template and Mg++ ions. Activity was only slightly enhanced by the addition of dithiothreitol. For maximum activity, the presence of all four deoxy-nucleoside triphosphates were required. Heat-denatured DNA was preferred as primer. The optimum pH for this enzymatic activity was found to be 7.2 in potassium phosphate buffer, and 8.0 in Trisacetate buffer. Time course studies on the enzyme reaction indicated that the reaction was linear with respect to incubation time for at least 30 min. The DNA polymerase activity was stable up to 13 days under temperature conditions of 4°C to -20°C. Glycerol in 20% to 35% (v/v) concentrations was found to have both a stimulatory and a stabilizing effect on the enzyme activity. Ethylene glycol at 20% (v/v) concentration was also found to have a stimulatory effect on the enzyme activity. The enzyme was strongly inhibited in the presence of 0,10 M phosphate ions and activity was drastically reduced in phosphate ion concentrations of 0.20 M and above. The product of the DNA polymerase reaction could be destroyed by DNase, indicating that it was DNA in nature. The purpose of the present work was to determine whether the DNA polymerase activity in the cytoplasmic preparation is actually of cytoplasmic origin, or whether it is due to nuclear contamination. The above results were compared with the results obtained by other workers on the nuclear DNA polymerases. The evidence seems to indicate that the cytoplasmic enzyme activity is not due to nuclear contamination. The nuclear preparation contained several DNA polymerases, while the cytoplasmic preparation contained a single major DNA polymerase activity. This cytoplasmic activity resembled one of the nuclear activities in many respects. The cytoplasmic preparation also contained a minor DNA polymerase activity which may be mitochondrial in origin.

Higher derivatives estimate for the 3D Navier-Stokes equation
Creators: name: Vasseur, Alexis F
Publisher: name: arXiv

Subjects: subject: Analysis of PDEs (math.AP)

subject: 76D05; 35Q30

description: In this article, a non linear family of spaces, based on the energy dissipation, is introduced. This family bridges an energy space (containing weak solutions to Navier-Stokes equation) to a critical space (invariant through the canonical scaling of the Navier-Stokes equation). This family is used to get uniform estimates on higher derivatives to solutions to the 3D Navier-Stokes equations. Those estimates are uniform, up to the possible blowing-up time. The proof uses blow-up techniques. Estimates can be obtained by this means thanks to the galilean invariance of the transport part of the equation.

Optimal scheduling and dispatch for hydroelectric generation
Creators: name: Tufegdzic, N
Publisher: name: University Of Tasmania
Year: 2023

description: The optimal operation of a power system has been investigated since early days of power systems. Special attention has been given to the optimal generation schedule, because significant savings can be achieved in this area. As predominantly hydro systems are not common, treatment of hydro in many cases has been connected with thermal operation and thermal fuel cost. Today with the open electricity market becoming reality in many countries, and decentralisation of the power industry representing the main trend, an independent hydro generator will become a reality and the necessity for optimisation of the predominantly or solely hydro system will increase. The major factors which affect optimal operation of the hydro system are: - Operation at maximum efficient point - Target level achievement(connected with mid and long term optimal operation) - Inflow (and load) uncertainty - Operation at the best head - Start up cost The new algorithm has been developed to take into account all those factors and produce optimal operation for a predominantly hydro system. The new algorithm presents real time hydro scheduling which is performed through regular rescheduling and look ahead dynamic economic dispatch. The full model is implemented including head variation and start-up costs. Mixed Integer Linear Programming (MILP) is chosen as the solution algorithm, because the linear programming part models the hydro network very effectively and the integer variables can be used to control the unit start-up and shut-down behaviour. The new techniques are developed to accommodate implementation of the MILP algorithm, such as power balance constraint relaxation, specific search techniques for integer solution and more detailed connection with mid-term optimisation. The algorithm is implemented on the Tasmanian Hydro Electric Commission's hydro system. It is tested off-line using historical operating plans. A conservative estimate is that the savings will be up to six hours daily of an operator's time plus 0.5% in annual stored energy savings. There is the possibility for savings in the mid term optimisation by decreasing the risk of spill through better control of short term storage levels.

description: There is an enormous potential in applying conjugated polymers in novel organic opto-electronic devices such as light emitting diodes and solar cells. Although prototypes and first products exist, a comprehensive understanding of the fundamental processes and energetics involved during photoexcitation is still lacking and limits further device optimisations. Here we report on a unique analysis of the excited states involved in charge generation by photoexcitation. On the model system poly(3-hexylthiophene) (P3HT), we demonstrate the general applicability of our novel approach. From photoemission spectroscopy of occupied and unoccupied states we determine the transport gap to 2.6 eV, which we show to be in agreement with the onset of photoconductivity by spectrally resolved photocurrent measurements. For photogenerated singlet exciton at the absorption edge, 0.7 eV of excess energy are required to overcome the binding energy; the intermediate charge transfer state is situated only 0.3 eV above the singlet exciton. Our results give direct evidence of energy levels involved in the photogeneration and charge transport within conjugated polymers.
