description: We fabricate artificial molecules composed of heavy atom lead on a van der Waals crystal. Pb atoms templated on a honeycomb charge-order superstructure of IrTe2 form clusters ranging from dimers to heptamers including benzene-shaped ring hexamers. Tunneling spectroscopy and electronic structure calculations reveal the formation of unusual relativistic molecular orbitals within the clusters. The spin-orbit coupling is essential both in forming such Dirac electronic states and stabilizing the artificial molecules by reducing the adatom-substrate interaction. Lead atoms are found to be ideally suited for a maximized relativistic effect. This work initiates the use of novel two dimensional orderings to guide the fabrication of artificial molecules of unprecedented properties.

description: Local bio-businesses are founded on unique making use of both standard and specific resources of territories on which they are established. The aim of the paper is to point to the role of institutions in creating local/regional bio-businesses. The analysis was conducted on the basis of three dimensions of the transformation of European model of agriculture: environmental regulations, dissemination of knowledge and information, inter-organizational and social connections. The degree of rooting of institutions which manage the establishment of bio-economy in social networks of users of agricultural holdings in Opole Province was identified on the basis of survey research. The work is of the cognitive and, partially, diagnostic character.

description: The ability to localize, identify and measure the electronic environment of individual atoms will provide fundamental insights into many issues in materials science, physics and nanotechnology. We demonstrate, using an aberration-corrected scanning transmission microscope, the spectroscopic imaging of single La atoms inside CaTiO3. Dynamical simulations confirm that the spectroscopic information is spatially confined around the scattering atom. Furthermore we show how the depth of the atom within the crystal may be estimated.

description: In der oberen Kruste sind Störungszonen üblicherweise aus komplexen Netzwerken von diskreten Brüchen unterschiedlicher Genese zusammengesetzt. Sie stellen daher meist maßgebliche Zonen bevorzugter unterirdischer Wasserwegigkeiten dar. Außerdem sind sie somit wesentlich für die hydrogeologische Beurteilung von Gebirgskörpern, da massive Wassereinbrüche im Untertagebau sehr häufig an Störungszonen gebunden sind. Solche Störungszonen zeigen für gewöhnlich eine räumlich-zeitliche Entwicklung vom Ausgangsgestein zu vollständig ausgeprägten Störungszonen mit einer internen strukturellen Gliederung (Protolith — damage zone — fault core). Die hydraulische Bewertung von Störungen ist ein wesentlicher Eingangsparameter für eine numerisch hydraulische Modellierung von Gebirgskörpern. Hierfür ist es notwendig das hydraulische Verhalten und die Wirksamkeit der verschiedenen Bereiche der Störung zu beschreiben und für die modellhafte Umsetzung mit hydraulischen Kenngrößen zu belegen. Das Ziel der Arbeit ist eine Korrelation von strukturgeologischen Parametern mit hydraulischen Parametern (kf , T, . . . ). Dies kann als eine hydraulische Kalibration der einzelnen Störungsklassen in Verbindung mit Wasserdurchlässigkeit angesehen werden. Für eine Fallstudie wurde als Testgebiet das Talhof-Störungssystem im Nordostteil der Ostalpen (Semmering- Raxgebiet, Österreich) gewählt...

description: We analyze absorption troughs from two outflows within PKS J0352-0711 (S1 at $-$1950 km s$^{-1}$ and S2 at $-$3150 km s$^{-1}$) from spectra taken with Hubble Space Telescope/Cosmic Origin Spectrograph, which cover the diagnostic-rich 585-900 Angstrom rest frame wavelength range. In S2, for the first time we clearly detect absorption troughs from Ca IV, Ca V, Ca V*, Ca VII*, and Ca VIII*. The column density measurement of Ca V suggests S2 has a super-solar metallicity. Both outflows require at least two ionization phases where the column density of the very high-ionization phase is roughly 15 times larger than the corresponding high-ionization phase. These high column densities and very high-ionization potential ions are similar to X-ray warm absorbers. The two phases of S2 show a unique velocity centroid shift between associated troughs. Through Monte Carlo measurements of the O V* absorption troughs, we determine the electron number density of S2 (fully corroborated by independent measurements from the Ca V* and Ca VIII* troughs), yielding a distance of 9 pc and a kinetic luminosity of 2$\times$10$^{43}$ erg s$^{-1}$. S1 is located farther away at 500 pc from the central source with a kinetic luminosity of 10$^{43}$ erg s$^{-1}$.

description: Dipole excitations below the neutron threshold in neutron rich Sn isotopes are studied theoretically in the Quasiparticle-Phonon Model with HFB single particle input. Of special interest are the low-lying two-phonon 1- states and the Pygmy Dipole Resonance (PDR). The evolution of low-energy dipole excitations with neutron excess is investigated over the Sn isotopic chain including the experimentally unknown regions close to 132Sn. A dependence of the PDR strengths and centroid energies on the neutron skin thickness is found. Despite significant multi-phonon contributions to mean energies and transition strengths, the PDR states retain their one-phonon character. The fragmentation pattern is reduced with increasing neutron excess towards the N=82 shell closure which will be of advantage for future experimental work.

description: The radiogeic 4He isotope is continuously forming in the lithosphere mainly by the alpha-decay of U, Th and Sm. This decay process was discovered already at the beginning of the 20th century, and the first U/He dating was made by Rutherford (1905). Although his result indicated that the dimensions of the Earth’s history ranges to millions of years, the U/He method was used only scarcely later on because the minerals are usually not closed to the decay product. The helium is extremely mobile and diffuse through the crystal lattices. Thus, the apparent U/He ages were always younger than the radiometric ages determined by other isotope geochronometers like U/Pb, Rb/Sr or K/Ar. The current renaissance of the method has been started at the end of eighties, when H. Lippolt, P. Zeitler, K. Farley and their co-workers have described the parameters of diffusion of some uraniumbearing minerals (e.g. Lippolt & Weigel 1987, Zeitler et al. 1987). It turned out that the (U-Th)/He apparent ages do carry meaningful geological information. The closure temperature of the most widely used apatite-He system is around 70°C. Thus, by the usage of this mineral/method pair it became possible to date low-temperature geological processes, which were undatable by other geochronometers...

description: The decomposition of an image into a linear combination of digitised basis functions is an everyday task in astronomy. A general method is presented for performing such a decomposition optimally into an arbitrary set of digitised basis functions, which may be linearly dependent, non-orthogonal and incomplete. It is shown that such circumstances may result even from the digitisation of continuous basis functions that are orthogonal and complete. In particular, digitised shapelet basis functions are investigated and are shown to suffer from such difficulties. As a result the standard method of performing shapelet analysis produces unnecessarily inaccurate decompositions. The optimal method presented here is shown to yield more accurate decompositions in all cases.

description: The Introduction defines 'Welsh Clergy' for the purposes of this study, i. e. those in the dioceses of St Asaph, Bangor, Liandaff and St David's, and sets out the objectives of the enquiry - to ascertain who the Welsh Clergy were in 1558-1642, and how far they conformed to the Reformation ideals of a learned and caring clergy. There follows a biographical study of each of the Welsh bishops in the period. In the following three sections, the clergy are studied in the categories - cathedral, sinecure and parochial. Next follows a consideration of the influence of the laity, including the Crown, on the clergy in the capacity of patrons and sureties. Evidence regarding the unbeneficed clergy (curates, chaplains and schoolmasters) follows. The remuneration of the clergy in Wales is discussed.. The Welsh clergy are next considered as communicators of the faith, and the study concludes with an assessment of how are standard improved among them in this period, with some considerations of their opposite numbers in England. In Volume II, the evidence is summarised in the form of tables.

description: The artilcle presents the market for microinstallations in Poland, the legal provisions governing instruments of support system prosumer energy and preliminary analysis of the profitability of the installation. In Poland, from 2013 on grows up rapidly the development of microinstallations connected to the energy network. At the end of March 2016 there were about 7,2 thousand with a total power of over 47 MW. Among them, in terms of quantity (94%) and power (80%) strongly dominated photovoltaic power plants. The amended law on renewable energy sources has introduced a new support system for prosumers in the form of discounts. The preliminary analysis of the profitability of PV installations with a power 3 kW in a single family home presented in three variants shows that it is economically advantageous for investors only with additional support investment.

description: The paper presents the changes in Polish foreign trade of fruits and their preserves in the years 2004-2014. Export and import of fruits and their products during the period fluctuated, ie. after periods of growth followed by declines. Export and import of fruits and their products in the period increased, the more their growth was observed in terms of value. In the structure of exports of fresh fruits dominated by apples, processed and frozen concentrated juices, mainly apple juice. The main recipient of Polish fruits of their preparations were EU countries, including the EU-15. In the structure of imports of fresh bananas dominated, and in the import of processed fruit juices concentrated. The main suppliers were the EU countries, mainly Germany, Spain and Italy. The introduction of the embargo by the Russian Federation on 1 August 2014 resulted in a decline in exports of fresh fruit in terms of volume and value, mainly apples. Extension of the embargo for manufacturers will mean continued problems with selling products. The embargo should speed up structural changes in the fruit and vegetable market, changes in the structure of Polish varietal fruit and vegetables, as well as the consolidation processes in the Polish fruit and vegetable sector.

description: The aim of this dissertation was to analyze and evaluate the functioning of farms in which agri-environmental program has been implemented. Field studies were carried out in 2015 in the Ostróda district and and covered the 62 beneficiaries of the program. Studies have shown that the agri-environmental program was implemented primarily in relatively large households (with an area exceeding the average in the country and in the Warmia and Mazury voivodeship). Farmers joining the program in most guided by financial issues. Only a few declared that importance was also protection of the environment. To the most popular packages were „Soil and water protection” and ,,Sustainable Agriculture”. In this case, the most significant were the economic considerations including the relative ease of implementation of the required measures. None of the farms were not conducted research on the environmental effects of the program.
Essays on retail price movements
Creators: name: Kano, Kazuko
Publisher: name: University of British Columbia
Year: 2011

description: The central questions asked in this thesis are (i) whether retail prices are sticky or not, and (ii) what economic factors are crucial for explaining retail price movements. In the second chapter, I first examine the predictions of two representative economic models to explain price movements - a time-dependent pricing model and a state-dependent pricing model. This chapter is different from past studies with respect to its micro data set including cost information. The results of this chapter based on descriptive statistics empirically support the state-dependent pricing model in explaining the observed retail price movements. Moreover, using reduced-form probit estimations to explain price changes, I show that the frequency of price changes is significantly affected by the degree of competitions among brands. The third chapter examines a state-dependent pricing model in the presence of fixed adjustment costs of prices - menu costs. A model with menu costs has the potential to explain an important characteristic of retail price movements: prices discretely jump. This chapter shows that the assumption about market structure is crucial in identifying menu costs. Specifically, prices in a tight oligopolistic market can be more rigid than those in more competitive market such as monopolistically competitive one. If so, the estimates of menu costs under the assumption of monopolistic competition in past studies are potentially biased upwards due to the rigidity from strategic interactions among brands. In addition, I show the estimate could be biased downwards without controlling for unobserved promotional activities. Developing and estimating a dynamic discrete-choice model with multiple agents to correct these potential biases, this chapter provides empirical evidence that menu costs as well as strategic interactions are important in explaining the observed degree of price rigidity in weekly price movements of a typical retail product, graham crackers. The fourth chapter provides a survey of the recently proposed estimators for structural estimations in dynamic discrete choice games. This survey focuses on two-step estimators, which overcome the computational costs that used to be unavoidable in the course of structural estimations of dynamic discrete-choice models.

description: We present the analysis of two outflows (S1 at --5500 km s$^{-1}$ and S2 at --9700 km s$^{-1}$) seen in recent HST/COS observations of quasar SDSS J0755+2306 (z = 0.854). The outflows are detected as absorption troughs from both high-ionization species, including N III, O III, and S IV, and very high-ionization species, including Ar VIII, Ne VIII, and Na IX. The derived photoionization solutions show that each outflow requires a two ionization-phase solution. For S1, troughs from S IV* and S IV allow us to derive an electron number density, $n_{e}$ = 1.8$\times$10$^4$ cm$^{-3}$, and its distance from the central source of $R$ = 270 pc. For S2, troughs from O III* and O III yield $n_{e}$ = 1.2$\times$10$^3$ cm$^{-3}$ and $R$ = 1600 pc. The kinetic luminosity of S2 is $>$ 12% of the Eddington luminosity for the quasar and therefore can provide strong AGN feedback effects. Comparison of absorption troughs from O III and O VI in both outflow systems supports the idea that for a given element, higher ionization ions have larger covering fractions than lower ionization ones.

description: We report the discovery of superconductivity in boron-doped diamond synthesized at high pressure (8-9 GPa) and temperature (2,500-2,800 K). Electrical resistivity, magnetic susceptibility, specific heat, and field-dependent resistance measurements show that boron-doped diamond is a bulk, type-II superconductor below the superconducting transition temperature Tc=4 K; superconductivity survives in a magnetic field up to Hc2(0)=3.5 T. The discovery of superconductivity in diamond-structured carbon suggests that Si and Ge, which also form in the diamond structure, may similarly exhibit superconductivity under the appropriate conditions.

Effects of damage-zone thickness on fault displacement
Creators: name: Gudmundsson, Agust

Publisher: name: Universitätsverlag Göttingen
Year: 2006

description: When viewed as ideal elastic cracks, seismogenic faults are often modeled as decreases from the host rock to the boundary between the core and the damage zone. mode II or mode III cracks in semiinfinite elastic bodies or half spaces. These models normally assume the rock to be homogeneous and isotropic. Such assumptions may be justified and necessary when using closed-form analytical solutions for fault displacement. They are not justified, however, when we attempt to understand fault-displacement profiles along earthquake rupture sites or in paleofault studies. This follows because crustal segments hosting faults are, as a rule, not homogeneous and isotropic, but rather heterogeneous and anisotropic. In particular, the fault rocks commonly form layers or units parallel with the fault plane. Also, the mechanical properties of the rocks next to the fault change as the fault develops (Gudmundsson 2004). During repeated earthquakes in a seismogenic fault zone, two main rock units develop around the fault plane. One unit is the core, located next to the fault plane and normally composed of soft (low Young’s modulus) breccia, gouge, and other cataclastic rocks. The other unit is the damage zone, containing some cataclastic rocks but characterized by fractures of various types...

description: An appealing feature of Network Function Virtualization (NFV) is that in an NFV-based network, a network function (NF) instance may be placed at any node. On the one hand this offers great flexibility in allocation of redundant instances, but on the other hand it makes the allocation a unique and difficult challenge. One particular concern is that there is inherent correlation among nodes due to the structure of the network, thus requiring special care in this allocation. To this aim, our novel approach, called CoShare, is proposed. Firstly, its design takes into consideration the effect of network structural dependency, which might result in the unavailability of nodes of a network after failure of a node. Secondly, to efficiently make use of resources, CoShare proposes the idea of shared reservation, where multiple flows may be allowed to share the same reserved backup capacity at an NF instance. Furthermore, CoShare factors in the heterogeneity in nodes, NF instances and availability requirements of flows in the design. The results from a number of experiments conducted using realistic network topologies show that the integration of structural dependency allows meeting availability requirements for more flows compared to a baseline approach. Specifically, CoShare is able to meet diverse availability requirements in a resource-efficient manner, requiring, e.g., up to 85% in some studied cases, less resource overbuild than the baseline approach that uses the idea of dedicated reservation commonly adopted for redundancy allocation in NFV.

description: The aim of this study was to compare the profitability of traditional cultivation of corn for grain dry, wet for the purpose to distilleries and the cultivation of corn silage using it for energy purposes as feedstock for the biogas plant. The highest yields were obtained in 2014: 9.70 t ha dry grain, 11.50 t/ha of wet grain and 55 t/ha of silage for the purpose of biogas. Gross margin of 1 ha of maize ranged from: 67.90 PLN/ha in 2015 (corn for silage into biogas) to 4308.80 PLN/ha (dry grain maize) in 2013, and was determined by the direction of growing corn and years of research. The income from 1 ha of crops including direct payments ranged from -2.60 PLN/ha in 2015 (the cultivation of grain dry) to 3060.30 PLN/ha in 2013 (crop silage into biogas). The biggest indicator of profitability over the years studied was achieved in the cultivation of corn for grain wet.
Scrap melting in a continuous process rotary melting furnace
Creators: name: Zhang, Yanjun
Publisher: name: University of British Columbia
Year: 2011

description: Based on the preliminary modeling study, an improved heat-transfer model has been developed in this study to further examine the viability of the oxy-fuel-fired continuous process rotary melting furnace (CPRMF) as a replacement of the electric arc furnace (EAF) in minimill steelmaking. The model treats the furnace as three domains: the freeboard space, the liquid metal bath and slag, and the refractory structure. Based on certain physical correct assumptions for the gas flow and combustion patterns, radiative exchange within the freeboard is solved by the zone method in combination with a clear-plus-3-gray emissivity/absorptivity model for the gas phase thus the model allows axial temperature variations in the gas phase and the refractory hot-face. Assuming an isothermal metal bath condition, heat transfer to the exposed bath is simplified by a specified temperature difference between the slag/freeboard and slag/metal interfaces, while regenerative heat transfer to the covered bath is calculated using the local refractory temperature and the local heat-transfer coefficients. The refractory structure is solved by 1-D transient conduction in the radial direction. The three domains are linked by shared boundary conditions and the requirement that the furnace itself operates at steady-state. The model was partially validated using experimental results from copper melting trials on a bench-scale CPRMF, which was designed and constructed as a part of work in this study. The trials explored two operating variables, i.e., oxygen and slag. Both experimental and model results indicate an increase in furnace thermal efficiency with increasing oxygen enrichment in the combustion air and a decrease in the efficiency with increasing slag thickness. The partially validated model was then employed to evaluate the commercial viability of the CPRMF. According to the model predictions, a melting rate in the order of 100 ton h⁻¹ can be achieved by a 4 m ID x 16 m furnace with a natural gas firing rate of 6000 Nm³ h⁻¹. Under the baseline conditions, the furnace thermal efficiency is 66%. Without scrap preheating, this configuration consumes less direct energy at 619 kWh t⁻¹ than the typical EAF (662 kWh t⁻¹) and can save at-source energy by about 45%.

We used a 3-D reflection seismic dataset in the northern LSB, provided by RWE-DEA AG, Hamburg (c.f. Lohr et al. submitted) for our investigation, which is concerned with the detailed structural and kinematic analysis of a flower structure within Mesozoic strata. This data is used in turn to determine input parameters for further 3-D geometrical retro-deformation. The retro-deformation verifies our assumptions about the structure and tectonic processes, and gives further information about sub-seismic strain distribution with respect to the branch faults of the flower structure.

description: We study a two-level atom in interaction with a real massless scalar quantum field in a spacetime with a reflecting boundary. The presence of the boundary modifies the quantum fluctuations of the scalar field, which in turn modifies the radiative properties of atoms. We calculate the rate of change of the mean atomic energy of the atom for both inertial motion and uniform acceleration. It is found that the modifications induced by the presence of a boundary make the spontaneous radiation rate of an excited inertial atom to oscillate near the boundary and this oscillatory behavior may offer a possible opportunity for experimental tests for geometrical (boundary) effects in flat spacetime. While for accelerated atoms, the transitions from ground states to excited states are found to be possible even in vacuum due to changes in the vacuum fluctuations induced by both the presence of the boundary and the acceleration of atoms, and this can be regarded as an actual physical process underlying the Unruh effect.

description: In the quest to image the three-dimensional magnetization structure we show that the technique of magnetic small-angle neutron scattering (SANS) is highly sensitive to the details of the internal spin structure of nanoparticles. By combining SANS with numerical micromagnetic computations we study the transition from single-domain to multi-domain behavior in nanoparticles and its implications for the ensuing magnetic SANS cross section. Above the critical single-domain size we find that the cross section and the related correlation function cannot be described anymore with the uniform particle model, resulting e.g. in deviations from the well-known Guinier law. We identify a clear signature for the occurrence of a vortex-like spin structure at remanence. The micromagnetic approach to magnetic SANS bears great potential for future investigations, since it provides fundamental insights into the mesoscale magnetization profile of nanoparticles.

description: Die Beziehungen zwischen der Mikrostruktur und der kristallografischen Vorzugsorientierung (Textur) von Hämatiterzen der gebänderten Eisenerzformation (BIF) in Brasilien wurden in vielen Veröffentlichungen behandelt, z.B. Quade et. al. 2000, Rosière et al. 2001, Bascou et al. 2002. Polfiguren dieser Hämatiterze zeigen kreisförmige bis elliptische c-Achsen-Maxima, die um den Pol der Foliation liegen. Die Pole der Prismenflächen liegen auf Großkreisen in der Foliationsebene und die Maxima auf diesen fallen mit der Lineation zusammen. Die Entstehung dieser Regelung wird auf Scherverformungprozesse zurückgeführt. Bei experimentellen Stauchversuchen an polykristallinem Hämatit gab es Anzeichen der Bildung eines c-Achsenmaximums senkrecht zur Kompressionsrichtung (Siemes et al. 2003). Da zu vermuten war, dass Gleiten parallel zur Basis des Hämatits Ursache der Regelung ist, wurden die Gleitmechanismen an experimentell verformten Hämatiteinkristallen bestimmt (Siemes et al. 2006). In diesem Beitrag werden neue Scherexperimente an polykristallinen Hämatitaggregaten vorgestellt...

description: Recent X-ray observations of clusters of galaxies have shown that the entropy of the intracluster medium (ICM), even at radii as large as half the virial radius, is higher than that expected from gravitational processes alone. This is thought to be the result of nongravitational processes influencing the physical state of the ICM. In this paper, we investigate whether heating by a central AGN can explain the distribution of excess entropy as a function of radius. The AGN is assumed to inject buoyant bubbles into the ICM, which heat the ambient medium by doing pdV work as they rise and expand. Several authors have suggested that this "effervescent heating" mechanism could allow the central regions of clusters to avoid the ``cooling catastrophe''. Here we study the effect of effervescent heating at large radii. Our calculations show that such a heating mechanism is able to solve the entropy problem. The only free parameters of the model are the time-averaged luminosity and the AGN lifetime. The results are mainly sensitive to the total energy injected into the cluster. Our model predicts that the total energy injected by AGN should be roughly proportional to the cluster mass. The expected correlation is consistent with a linear relation between the mass of the central black hole(s) and the mass of the cluster, which is reminiscent of the Magorrian relation between the black hole and bulge mass.

description: In the literature the most frequently cited data are quite contradictory, and there is no consensus on the global minimum value of 2D Edwards-Anderson (2D EA) Ising model. By means of computer simulations, with the help of exact polynomial Schraudolph-Kamenetsky algorithm, we examined the global minimum depth in 2D EA-type models. We found a dependence of the global minimum depth on the dimension of the problem N and obtained its asymptotic value in the limit $N\to\infty$. We believe these evaluations can be further used for examining the behavior of 2D Bayesian models often used in machine learning and image processing.

description: The paper is an attempt to assess the level of competitiveness of Polish dairy sector in the European Union market. Special attention has been paid to the state of the Polish producers price advantage relative to the EU’s main competitors, ie. the largest producers and exporters of milk and dairy products in the European Union. The study covered the years 2012-2015. In creating competitive advantage in the Polish dairy sector prices play vital role. This is indicated by both the analysis of market prices of basic products, of dairy sector. Which are lower in Poland than in the EU-15 countries, as well as analysis of prices in the following long of the food chain. In the future, it is expected that Polish dairy producers manage to maintain a price advantage in the EU market, however their level will be systematically reduced.

title: Towards the absolute quantification of DNA by PCR
Creators: name: Burns, Nigel
Publisher: name: The Open University

description: Amplification techniques such as the Polymerase Chain Reaction (PCR) are held to be largely qualitative procedures and are widely used as such. Since the efficiency of amplification is less than perfect, small changes in efficiency can yield dramatic differences in the final amount of product generated. Despite this unpredictability the exquisite sensitivity of PCR makes the demanding goal of absolute quantification highly desirable. Consequently, the use of this technique for the quantification of nucleic acids has increased at an exponential rate. However, the ability of PCR to accurately quantify absolute levels of DNA is still not universally accepted.

The overall aim of this investigation was to determine the critical factors affecting the quantification of DNA using PCR and to use these findings to develop an assay for the absolute quantification of DNA in a model system. The novel work presented here illustrates the need for careful examination of sequences for GC-rich domains which could give rise to stable secondary structures and reduce the efficiency of amplification by serving as termination sites.

To determine the accuracy of competitive PCR, CE and IP-RP-HPLC were employed to quantify PCR- products. These two techniques provided valuable information on the identification and elimination of sources of error which led to improvements in speed, accuracy and precision, as well as ease of quantification by PCR. They also yielded information on the process of heteroduplex formation whilst simultaneously revealing assay limitations.

Consequently, the on-line fluorescence monitoring of PCR was used as an alternative method for the quantification of Legionella pneumophila. This technique was highly reproducible however, mispriming and the subsequent amplification of non-specific PCR products limited the level of detection. The Y-end labelling of degraded DNA with DIG prevented short DNA fragments from mispriming (and consequently extending) allowing the amplification of DNA targets. Therefore, to reduce mispriming and hence improve assay sensitivity, this approach was adapted for the first time to produce 5'-degenerate, 3'- DIG-terminated competitive primer analogues. These analogues, coupled with the use of the LightcyclerTM, allowed the detection and absolute quantification of a single cell of Legionella pneumophila. This is the first time that this level of sensitivity has been achieved using this type of assay.

This technique should provide a very rapid and sensitive alternative for quantification compared to the other, more expensive technologies available at present.
