description: We identify universal quasiconformal (walking) behaviour in non-Abelian gauge field theories based on the mass-dependent all-order beta-function introduced in arXiv:0908.1364. We find different types of walking behaviour in the presence of (partially) massive species. We employ our findings to the construction of candidate theories for dynamical electroweak symmetry breaking by walking technicolour.

description: A single-electron transistor has been realized in a Ga[Al]As heterostructure by oxidizing lines in the GaAs cap layer with an atomic force microscope. The oxide lines define the boundaries of the quantum dot, the in-plane gate electrodes, and the contacts of the dot to source and drain. Both the number of electrons in the dot as well as its coupling to the leads can be tuned with an additional, homogeneous top gate electrode. Pronounced Coulomb blockade oscillations are observed as a function of voltages applied to different gates. We find that, for positive top-gate voltages, the lithographic pattern is transferred with high accuracy to the electron gas. Furthermore, the dot shape does not change significantly when in-plane voltages are tuned.

description: We consider the scalar wave equation in the Kerr geometry for Cauchy data which is smooth and compactly supported outside the event horizon. We derive an integral representation which expresses the solution as a superposition of solutions of the radial and angular ODEs which arise in the separation of variables. In particular, we prove completeness of the solutions of the separated ODEs. This integral representation is a suitable starting point for a detailed analysis of the long-time dynamics of scalar waves in the Kerr geometry.

Year: 2020
Subjects: subject: 004 Data processing Computer sciences

description: Model checking is the automated verification that systematically checks if a given behavioral property holds for a given model of a system. We use Petri nets and temporal logic as formalisms to describe a system and its behavior in a mathematically precise and unambiguous manner. The contributions of this thesis are concerned with the improvement of model checking efficiency both in theory and in practice. We present two new reduction techniques and several supplementary strength reduction techniques. The thesis also enhances partial order reduction for certain temporal logic classes.

The award recognizes exemplary student work that achieves the learning outcomes of the Signature Course information literacy requirement, that students will be able to create and execute a research strategy, critically evaluate information, and navigate the scholarly conversation. Caitlyn Kung's paper "New York City Bitch: Linguistic Appropriation and Awkwafina's Negotiation of Ethnic Identity Through Rap," was self-nominated in Almeida Toribio's UGS 303 class Language and Ethnic Identity. Her TA Drew Colcher said in support of her paper, "Caitlyn’s final essay demonstrated that she grasped the nuances of this field more than any other student in the class. Her unique project on the use of African American Vernacular English in the music of Asian-American entertainer Awkwafina included a detailed focus on specific linguistic features associated with various ethnic identities in the U.S. Her methodology, analysis, and conclusions were well-founded and flowed logically, and her references to resources beyond those read for class allowed her to situate her research in a compelling manner. I believe that Caitlyn’s paper illustrates advanced investigatory and argumentative abilities, and strong potential for future research endeavors."
description: Chinese-American actress and musician Awkwafina has operated in a novel cross-cultural language space due to her unique position as a non-Black person of color who grew up familiar with African American English (AAE). Previous works have evaluated the authenticity of AAE by white and immigrant speakers, but so rarely has its usage by American-born people of color been examined. Awkwafina’s entire discography was examined in comparison to various interviews and spoken dialogue clips in order to assess the authenticity of her employment of AAE. Phonological and grammatical accuracy were evaluated in addition to Awkwafina’s usage of AAE slang terms in order to determine whether her on-stage persona was simply a face put on at the expense of African American culture or if her intimate knowledge of AAE in conjunction with her engagement with her Asian American identity provides new understandings of multi-ethnic social spaces.

description: We fabricated quantum wires of different geometries in Ga[Al]As heterostructures by local oxidation of the semiconductor surface with an atomic force microscope. By magnetotransport measurements at low temperatures on these wires the electronic width is determined and compared to the geometrical width. An extremely small lateral depletion length of the order of 15 nm and a high specularity of the scattering at the confining walls is found. Furthermore, we demonstrate experimentally that these quantum wires can be tuned by a combination of in-plane gates and top gates.

description: Adiabatic quantum algorithms are characterized by their run time and accuracy. The relation between the two is essential for quantifying adiabatic algorithmic performance, yet is often poorly understood. We study the dynamics of a continuous time, adiabatic quantum search algorithm, and find rigorous results relating the accuracy and the run time. Proceeding with estimates, we show that under fairly general circumstances the adiabatic algorithmic error exhibits a behavior with two discernible regimes: the error decreases exponentially for short times, then decreases polynomially for longer times. We show that the well known quadratic speedup over classical search is associated only with the exponential error regime. We illustrate the results through examples of evolution paths derived by minimization of the adiabatic error. We also discuss specific strategies for controlling the adiabatic error and run time.

description: Abstract
The study examines the mechanism of cheque truncation system initiated by RBI, through positive pay system. This study evaluates the effectiveness of positive pay system by banker's angle and customer's angle. Valid and reliable two separate questionnaires were designed for understanding the impact of positive pay system through customers' perspective and through bankers' perspective. The required data is collected from customers of the bank and from those banks who initiated positive pay system. Around 50 samples of customer and 35 samples of bank are considered for the study. One sample t test is used to test the hypothesis. This study demonstrates that customers are more comfortable in using the internet banking; UPI modes of payments, so they are not much inclined towards the use of cheque payments, hence they are not interested in using the PPS subsequently. The result of this study reflects that the efforts are still not up to the mark and needs to improvise via different means to motivate to customer to use positive pay system.

description: Background & aims: Individuals with fasting triglycerides (TG) <150 mg/dL can experience a deleterious postprandial TG response 220 mg/dL to a high-fat meal (HFM). The purpose of this study was to identify individuals based on fasting TG that would benefit most from additional postprandial screening. Methods: We conducted a secondary analysis of 7 studies from our laboratories featuring 156 diseasefree participants (64 M, 92 F; age 18e70 years; BMI 18.5e30 kg/m2). Participants observed a 10e12 h overnight fast, after which they consumed an HFM (10e13 kcal/kg body mass; 61e64% kcal from fat). Two methods were used to identify lower and upper fasting TG cut points. Method 1 identified the lower limit as the TG concentration at which 90% of individuals presented peak postprandial TG (PPTG) <220 mg/dL and the upper limit as the concentration which 90% of individuals presented PPTG 220 mg/dL. Method 2 utilized receiver operating characteristic (ROC) curves and identified the lower limit as the fasting TG concentration where sensitivity was z95% and the upper limit as the concentration at which specificity was z95%. Results: In Method 1, 90% of individuals with fasting TG >130 mg/dL (>1.50 mmol/L) exhibited PPTG 220 mg/dL ( 2.50 mmol/L), while 100% of individuals with fasting TG <66 mg/dL (0.75 mmol/L) had PPTG that did not exceed 220 mg/dL (2.50 mmol/L). In Method 2, when sensitivity was z95%, the corresponding fasting TG concentration was 70 mg/dL (0.79 mmol/L). When specificity was z95%, the corresponding fasting TG concentration was 114 mg/dL (1.29 mmol/L). Based on methods 1 and 2, there was a moderate positive association (r ¼ 0.37, p < 0.004) between fasting and PPTG for individuals with fasting TG between 70 and 130 mg/dL (0.79e1.50 mmol/L), in which 24% exhibited PPTG 220 mg/dL ( 2.50 mmol/L) while 76% did not. Conclusions: Postprandial TG testing is likely most useful for individuals with fasting TG concentrations between 70 and 130 mg/dL (0.79e1.50 mmol/L). Outside of this range, postprandial TG responses are largely predictable. Establishing a specific patient group for which postprandial TG testing is most useful may lead to earlier risk detection in these individuals.

description: Based on the Wilemski-Fixman approach (J. Chem. Phys. 60, 866 (1974)) we showed that for a flexible chain in theta solvent hydrodynamic interaction treated with an pre-averaging approximation makes ring closing faster if the chain is not very short. Only for a very short chain the ring closing is slower with hydrodynamic interaction on. We have also shown that the ring closing time for a chain with hydrodynamic interaction in theta solvent scales with the chain length (N) as N^(1.527), in good agreement with previous renormalization group calculation based prediction by Freidman et al. (Phys. Rev. A. 40, 5950 (1989)).

description: Microbial genomes harbor genomic islands (GIs), genes presumably acquired via horizontal gene transfer (HGT). We compared GIs of hyperthermophilic, thermophilic, mesophilic, and pathogenic/nonpathogenic species and of small and large genomes. The COG database was used to characterize gene-encoded functions. Putative donors were determined to quantify gene flux between superkingdoms. In hyperthermophiles, more than 10% of the genes were on average acquired across the superkingdom border. For thermophiles and particularly mesophiles, we identified a nearly unidirectional export from bacteria to archaea. Additionally, we analyzed GI composition for Escherichia, and pairs of Listeria, Rhizobiales, Methanosarcinaceae, and Thermus thermophilus/Deinococcus radiodurans. For Escherichia and Listeria, the composition of GIs in pathogenic and nonpathogenic species did not differ significantly with respect to encoded COG classes. The analysis of related genomes showed that the composition of GIs cannot be explained with trends of gene content known to depend on genome size.

description: We propose late-time moduli decay as the common origin of baryons and dark matter. The baryon asymmetry is produced from the decay of new TeV scale particles, while dark matter is created from the (chain) decay of R-parity odd particles without undergoing any annihilation. The baryon and dark matter abundances are mainly controlled by the dilution factor from moduli decay, which is typically in the range 10^{-9}-10^{-7}. The exact number densities are determined by simple branching fractions from modulus decay, which are expected to be of similar order in the absence of symmetries. This scenario can naturally lead to the observed baryon asymmetry and, for moderate suppression of the two-body decays of the modulus to R-parity odd particles, can also yield the correct dark matter abundance for a dark matter mass in the (5-500) GeV range.

description: The genome of Bacillus licheniformis DSM13 consists of a single chromosome that has a size of 4,222,748 base pairs. The average G+C ratio is 46.2%. 4,286 open reading frames, 72 tRNA genes, 7 rRNA operons and 20 transposase genes were identified. The genome shows a marked co-linearity with Bacillus subtilis but contains defined inserted regions that can be identified at the sequence as well as at the functional level. B. licheniformis DSM13 has a well-conserved secretory system, no polyketide biosynthesis, but is able to form the lipopeptide lichenysin. From the further analysis of the genome sequence, we identified conserved regulatory DNA motives, the occurrence of the glyoxylate bypass and the presence of anaerobic ribonucleotide reductase explaining that B. licheniformis is able to grow on acetate and 2,3-butanediol as well as anaerobically on glucose. Many new genes of potential interest for biotechnological applications were found in B. licheniformis; candidates include proteases, pectate lyases, lipases and various polysaccharide degrading enzymes.
The clearing of discs around late type T Tauri stars: constraints from the infrared two colour plane

description: We have undertaken SED modeling of discs around low mass T Tauri stars in order to delineate regions of the infrared two colour plane (K - [8] versus K - [24]) that correspond to discs in different evolutionary stages. This provides a ready tool for classifying the nature of star-disc systems based on infrared photometry. In particular we demonstrate the distinct loci followed by discs that undergo `uniform draining' (reduction in surface density by a spatially uniform factor) from those that clear from the inside out. We draw attention to the absence of objects on this `draining locus' in those star forming regions where the 24um sensitivity would permit their detection, as compared with the ~20 objects in these regions with colours suggestive of inner holes. We thus conclude that discs predominantly clear from the inside out. We also apply our classification of the infrared two colour plane to stars of spectral type M3-M5 in the IC 348 cluster and show that some of its members (dubbed `weak excess' sources by Muzerolle et al 2010) that had previously been assumed to be in a state of clearing are instead likely to be optically thick discs in which the dust is well settled towards the mid-plane. Nevertheless, there are many discs in a state of partial clearing in IC 348, with their abundance (relative to the total population of disc bearing stars) being around four times higher than for comparable stars in Taurus. However, the number of partially cleared discs relative to the total number of late type stars is similarly low in both regions (10 and 20 % respectively). We therefore conclude that IC 348 represents a more evolved version of the Taurus population (with more of its discs being highly settled or partially cleared) but that the timescale for clearing is similarly short (a few times 10^5 years) in both cases.

description: Monoclonal antibodies against a glycoprotein presumably involved in adhesion of aggregating Dictyostelium discoideum cells have been used for labeling of the antigen at the cell surface. The antigen is distributed over the whole surface of the cells, apparently in form of small clusters. The antigen appears concomitantly with the acquisition of EDTA-stable adhesiveness typical of aggregation competent cells. In contrast, discoidin I, a lectin whose accumulation during development parallels EDTA-stable adhesiveness in another strain (NC-4), is present in nearly the same amounts of growth phase and aggregating cells of AX2-214, the strain used by use. Thus, no correlation exists in this strain between the expression of discoidin I and the development of cell adhesiveness. The 80 kilodalton glycoprotein typical of aggregation competent cells has been purified by affinity chromatography on a monoclonal antibody column. The purified antigen absorbs adhesion-blocking Fab from rabbits. Another antigen strongly reacting with the same monoclonal antibodies has an apparent molecular weight of 106 000 and is not detectable before slugs are formed.
Numerical weather prediction for electrical transmission lines
Creators: name: Campbell, Margaret
Publisher: name: University of British Columbia
Year: 2018

description: Joule heating from electrical currents causes the conductor temperature of a transmission line to increase. Weather can further heat or cool the line. Wind speed and direction have the largest effect (CIGRE 2006), followed by air temperature. Utility companies need to know the maximum current they can transmit without exceeding critical temperature thresholds for transmission line safety (e.g., excess sag or metallurgical damage). The maximum transmittable electrical current for safe transmission (ampacity) must be estimated from wind speed, direction, temperature, insolation, and maximum conductor temperature. Power utilities apply this thermal rating to all powerlines. Traditional thermal rating methods do not monitor the weather surrounding powerlines, but assume relatively constant weather, leading to either overly conservative or unsafe thermal ratings. Dynamic thermal ratings (DTRs) take into account varying weather conditions in an effort to more realistically represent ampacity variations. To demonstrate the potential of DTR forecasts based on numerical weather prediction (NWP) forecasts to improve powerline safety, increase transmission capacity, and provide power utilities a means of advanced planning, this thesis 1) evaluates and compares seven bias-corrected, calibrated DTR forecast configurations to two traditional thermal rating methods to determine the most skillful DTR forecast method as well as to show the usefulness of probabilistic forecasts. 2) Determines raw DTR forecasts along a powerline to assess the degree and cause of spatial DTR forecast variability. The most skillful DTR forecasts start with bias-corrected NWP forecasts from which DTRs are calculated and combined into an ensemble average, which is then bias-corrected again and calibrated. The 1st, 5th, and 10th DTR forecast percentiles are safer than traditional thermal rating methods, while the 20th - 50th DTR forecast percentiles allow higher transmission capacity. Extensive temporal and spatial DTR forecast variability along a powerline results from wind speed forecast variability. Based on this research, it is recommended that utility companies use hourly DTR forecasts at their transmission line to maximize both current and safety.

description: The optical properties of T-shaped GaAs/AlGaAs quantum wire (QWR) waveguide structures are studied with a magnetic field oriented parallel or perpendicular to the QWR axis. The QWRs were fabricated by the cleaved edge overgrowth (CEO) technique. At low values of the magnetic field oriented perpendicular to the QWR axis, a strong increase in the light emission intensity is observed for all injection currents. For the magnetic field direction parallel to the QWR axis a completely different behavior is found. For magnetic fields greater than 4 T a decrease in the intensity of the emitted light for injection currents below 0.125 mA is observed, while an increase is measured for injection currents larger than 0.125 mA. The origin of the effects induced by the magnetic field is interpreted in terms of optical properties of a one-dimensional (1D) system.

description: We study the evolution of time-dependent fluctuations and particle production in an expanding dS and contracting AdS universe. Using the functional Schrodinger formalism we are able to probe the time dependent regime which is out of the reach of the standard approximations like the Bogolyubov method. In both cases, the evolution of fluctuations is governed by the harmonic oscillator equation with time dependent frequency. In the case of an expanding dS universe we explicitly show that the frequency of fluctuations produced at a certain moment diminish in time, while the distribution of the created particles quickly approaches the thermal radiation of the dS space. In the case of a contracting AdS universe we show that the frequency of fluctuations produced at a certain moment grow in time. Nominally, the temperature of radiation diverges as the Big Crunch is approaching, however, increasing oscillations of the spectrum make the temperature poorly defined, which is in agreement with the fact that AdS space does not have an event horizon which would cause thermal radiation. Unlimited growth of fluctuations indicates that an eventual tunneling into AdS vacuum would have catastrophic consequences for our universe.

description: I present an inverse function theorem for differentiable maps between Frechet spaces which contains the classical theorem of Nash and Moser as a particular case. In contrast to the latter, the proof does not rely on the Newton iteration procedure, but on Lebesgue's dominated convergence theorem and Ekeland's variational principle. As a consequence, the assumptions are substantially weakened: the map F to be inverted is not required to be C^2, or even C^1, or even Frechet-differentiable.

description: It has been known for some time that the Milky Way is a barred disk galaxy. More recently several studies inferred from starcount observations that the Galaxy must contain a separate, new, flat long bar component, twisted relative to the barred bulge. Here we use a simulation with a boxy bulge and bar to suggest that these observations can be reproduced with a single structure. In this simulation a stellar bar evolved from the disk, and the boxy bulge originated from it through secular evolution and the buckling instability. We calculate starcount distributions for this model at different longitudes and latitudes, in a similar way as observers have done for resolved starcounts. Good agreement between the simulation and the observations can be achieved for a suitable snapshot, even though the simulation has a single boxy bulge and bar} structure. In this model, part of the long bar signature is due to a volume effect in the starcounts, and another part is due to chosing a snapshot in which the planar part of the boxy bulge and bar has developed leading ends through interaction with the adjacent spiral arm heads. We also provide predictions from this model for the line-of-sight velocity distributions at the longitudes with the long bar signature, for comparison with upcoming surveys.

description: We examine the physical properties and evolutionary stages of a sample of 17 clumps within 8 Infrared Dark Clouds (IRDCs) by combining existing infrared, millimeter, and radio data with new Bolocam Galactic Plane Survey (BGPS) 1.1 mm data, VLA radio continuum data, and HHT dense gas (HCO+ and N2H+) spectroscopic data. We combine literature studies of star formation tracers and dust temperatures within IRDCs with our search for ultra-compact (UC) HII regions to discuss a possible evolutionary sequence for IRDC clumps. In addition, we perform an analysis of mass tracers in IRDCs and find that 8 micron extinction masses and 1.1 mm Bolocam Galactic Plane Survey (BGPS) masses are complementary mass tracers in IRDCs except for the most active clumps (notably those containing UCHII regions), for which both mass tracers suffer biases. We find that the measured virial masses in IRDC clumps are uniformly higher than the measured dust continuum masses on the scale of ~1 pc. We use 13CO, HCO+, and N2H+ to study the molecular gas properties of IRDCs and do not see any evidence of chemical differentiation between hot and cold clumps on the scale of ~1 pc. However, both HCO+ and N2H+ are brighter in active clumps, due to an increase in temperature and/or density. We report the identification of four UCHII regions embedded within IRDC clumps and find that UCHII regions are associated with bright (>1 Jy) 24 micron point sources, and that the brightest UCHII regions are associated with "diffuse red clumps" (an extended enhancement at 8 micron). The broad stages of the discussed evolutionary sequence (from a quiescent clump to an embedded HII region) are supported by literature dust temperature estimates; however, no sequential nature can be inferred between the individual star formation tracers.

description: We estimated the dynamical surface mass density (Sigma) at the solar Galactocentric distance between 2 and 4 kpc from the Galactic plane, as inferred from the observed kinematics of the thick disk. We find Sigma(z=2 kpc)=57.6+-5.8 Mo pc^-2, and it shows only a tiny increase in the z-range considered by our investigation. We compared our results with the expectations for the visible mass, adopting the most recent estimates in the literature for contributions of the Galactic stellar disk and interstellar medium, and proposed models of the dark matter distribution. Our results match the expectation for the visible mass alone, never differing from it by more than 0.8 $Mo pc^-2 at any z, and thus we find little evidence for any dark component. We assume that the dark halo could be undetectable with our method, but the dark disk, recently proposed as a natural expectation of the LambdaCDM models, should be detected. Given the good agreement with the visible mass alone, models including a dark disk are less likely, but within errors its existence cannot be excluded. In any case, these results put constraints on its properties: thinner models (scale height lower than 4 kpc) reconcile better with our results and, for any scale height, the lower-density models are preferred. We believe that successfully predicting the stellar thick disk properties and a dark disk in agreement with our observations could be a challenging theoretical task.

description: Background: Horizontal gene transfer (HGT) is considered a strong evolutionary force shaping the content of microbial genomes in a substantial manner. It is the difference in speed enabling the rapid adaptation to changing environmental demands that distinguishes HGT from gene genesis, duplications or mutations. For a precise characterization, algorithms are needed that identify transfer events with high reliability. Frequently, the transferred pieces of DNA have a considerable length, comprise several genes and are called genomic islands (GIs) or more specifically pathogenicity or symbiotic islands. Results: We have implemented the program SIGI-HMM that predicts GIs and the putative donor of each individual alien gene. It is based on the analysis of codon usage (CU) of each individual gene of a genome under study. CU of each gene is compared against a carefully selected set of CU tables representing microbial donors or highly expressed genes. Multiple tests are used to identify putatively alien genes, to predict putative donors and to mask putatively highly expressed genes. Thus, we determine the states and emission probabilities of an inhomogeneous hidden Markov model working on gene level. For the transition probabilities, we draw upon classical test theory with the intention of integrating a sensitivity controller in a consistent manner. SIGI-HMM was written in JAVA and is publicly available. It accepts as input any file created according to the EMBL-format. It generates output in the common GFF format readable for genome browsers. Benchmark tests showed that the output of SIGI-HMM is in agreement with known findings. Its predictions were both consistent with annotated GIs and with predictions generated by different methods. Conclusion: SIGI-HMM is a sensitive tool for the identification of GIs in microbial genomes. It allows to interactively analyze genomes in detail and to generate or to test hypotheses about the origin of acquired genes.

description: In dieser Studie wurden Prädiktoren, sowie der Einfluss eines Kindheitstraumas auf die Krankheitsverarbeitung und die Entwicklung des psychologischen Konstrukts der Posttraumatischen Reifung (PR) bei Melanompatient*innen untersucht. PR ist als eigenständiges Konstrukt von der Resilienz abzugrenzen und beinhaltet einen Zugewinn neuer Perspektiven i.R. der Traumverarbeitung. Als positive Prädiktoren konnten u.a. bestimmte Copingmechanismen sowie dissoziative Verarbeitungsmechanismen identifiziert werden. Eine eindeutige Korrelation zwischen einem Kindheitstrauma und der PR ließ sich nicht belegen.

description: This paper introduces a new object called the momentum tensor. Together with the velocity tensor it forms a basis for establishing the tensorial picture of classical and relativistic mechanics. Some properties of the momentum tensor are derived as well as its relation with the velocity tensor. For the sake of clarity only two-dimensional case is investigated. However, general conclusions are also valid for higher dimensional spacetimes.

description: Die Arbeit untersucht die Auswirkungen einer antibiotikaassoziierten Clostridioides difficile-Infektion auf die Rheumatoide Arthritis im Mausmodell. Sowohl die Inzidenz als auch die Schwere der kollagen-induzierten Arthritis wurde durch die vorhergehende Infektion mit dem Clostridienstamm VPI 10463 stark abgeschwächt. Mikrobiomanalysen aus extrahierter DNA von Mäusestuhlproben zeigten Veränderungen in der Zusammensetzung während des Experiments. Die Arbeit gibt damit Hinweise auf einen möglichen Zusammenhang zwischen Infektion, Mikrobiom und der autoimmunen Genese der Rheumatoiden Arthritis.

description: The rising costs of fertilisers, disruptions in supply chains due to COVID-19 and global conflicts, and a focus on soil health have led to increased interest among growers in using alternative inputs for improved cropping systems. Recycled organics derived from intensive livestock operations and food waste contain valuable nutrients and organic matter, which can enhance soil characteristics, increase crop productivity, reduce reliance on inorganic fertilisers, and promote resilient farming systems. The Incitec Pivot Fertilisers’ (IPF) Australia biofertilisers (ABF) is made with a sterilised and dried organic waste materials from poultry sheds, combined with inorganic chemicals, resulting in organo-mineral granules that provide necessary nutrients, organic matter, and labile carbons in a single granule. ABF technology is one example of efficient waste recycling where most of the nutrients and carbon are retained from the waste as opposed to being lost to the atmosphere as greenhouse gases, in alignment with the principles of circular economy. The main barriers to adoption are the high capital cost of building in Australia and the cost of renewable energy to run the process. Similar challenges are faced by other emerging technologies such as green ammonia. Perhaps the greatest opportunity for farmers is to adopt inhibitors which can minimise gaseous and leaching losses from existing nitrogen fertilisers. Nitrogen fertilisers are essential to crop production, but more than half of the fertiliser applied to crops is lost due to leaching or volatilisation. The IPF inhibitors can reduce greenhouse gas emissions by up to 80% from fertilisers and in some cases allow rate reduction without impacting yield and quality of produce. IPF conducted a study comparing their patented technologies of biofertilisers and nitrification inhibitors with standard farming practices for celery cultivation in East Victoria, demonstrating similar crop yields, reduced emissions and providing application efficiency.
