description: To date, exploiting the full bandwidth of state-of-the-art InGaAs photomixers for generation and detection of continuous-wave (CW) THz radiation (typ. ~50 GHz to ~3 THz) required complex and costly external-cavity diode lasers with motorized resonator control. Distributed feedback (DFB) lasers, by contrast, are compact and inexpensive, but the tuning range per diode is limited to ~600 GHz at 1.5 μm. In this paper, we show that a combination of three DFB diodes covers the complete frequency range from 0 – 2750 GHz without any gaps. In combination with InGaAs-based photomixers for terahertz generation and detection, the system achieves a dynamic range of > 100 dB at 56 GHz, 64 dB at 1000 GHz, and 26 dB at 2500 GHz. A field-programmable gate array (FPGA)-based lock-in amplifier permits a flexible adjustment of the integration time from 0.5 ms to 600 ms. Employing an optimized “fast scan” mode, a spectrum of ~1200 GHz – the bandwidth of each subset of two lasers – and 40 MHz steps is acquired in less than one minute, still maintaining a reasonable dynamic range. To the best of our knowledge, the bandwidth of 2.75 THz presents a new record for DFB-based CW-terahertz systems.

description: Background

In-situ simulation-based learning (SBL) is an established Healthcare Education strategy.   However the provision of consistent high-quality SBL that supports the diverse learning needs of a multi-disciplinary team can be challenging. 



Summary Of Work

A program of weekly high-fidelity, in-situ SBL was implemented on the General Intensive Care Unit (GICU) of a London Teaching Hospital.  Core faculty included two Intensive Care Registrars and four Practice Education Nurses.  Participation was optional with participants recruited from available staff.



Sessions included twenty minutes each for pre-brief, simulation, and debrief.  Pre-brief established a safe and inclusive learning environment, with learners encouraged to self-identify personal learning outcomes and the scenario run in the way felt to best support these outcomes.  Facilitated debrief supported learners through the experiential and reflective learning processes. 

Data was collected between November 2021 – May 2022, incorporating learner feedback questionnaires, issues, and identified hazards.



Summary Of Results

17 sessions took place covering 5 topics.   61 learners (mean 3.6 participants/session) included Doctors (45.9%), Nurses (39.3%), and students/other (14.7%).  78% of total GICU junior doctors participated compared to 21% of nurses, although data on repeat-attenders was not collected.  11 (39%) of potential sessions were cancelled, mostly due to faculty availability (43%) and inadequate staffing (29%).

82% of learners rated ‘Improved knowledge and confidence’ as 9 or 10 on a 10-point Likert scale.  91.7% of nurses and 85.7% of doctors rated overall training quality as excellent.  Qualitative feedback was also very positive.  Potential hazards identified related to airway equipment and guideline accessibility.  



Discussion And Conclusion

Whilst highly rated by participants, challenges to the provision of regular in-situ SBL within the wider context of clinical and staffing pressures is reflected in the high proportion of cancelled sessions.  Positive learner feedback across disciplines evidences the inclusive nature of the education strategy.  However, the relatively low proportion of GICU nurses accessing training raises concerns regarding equality of opportunity.  Exploring and addressing barriers to participation and session provision will be essential in improving the inclusivity and sustainability of this valuable program.



Take Home Messages

Regular, in-situ SBL on the ICU benefits staff and departments.  Future work should seek to improve equality of access and address barriers to session provision.

The potential of air freight in relation to British Columbia economy and trade
Creators: name: Tapiero, Michel
Publisher: name: University of British Columbia

description: Transportation of commodities by air during the past decade has experienced the fastest growth of all modes of transport. Although a slowdown had been predicted by shippers and carriers alike, the economic recession of 1969 has had only mild effects on the air freight industry. In this study, the potential for air freight has been examined in terms of the concept of total distribution cost. The study has focused on the potential for air freight within B.C. but more particularly on B.C. external trade with Japan and on the means whereby this potential may best be realized. Cost analysis for specific commodities by air transport as compared to sea container transport illustrates the application of the Total Distribution Cost Concept. Brief mention is made of the back-haul freight problems faced by B.C.- based air carriers. Potential for air freight in the containerized commodity market is examined in the light of present and future aircraft capacity and performance, together with possible air/ surface transport coordination. The conclusions of the study are as follows : the convenience and cost savings derived from the use of air transport do not appear, as yet, to compensate for the present air transportation charges ; air-freight rate reductions may not necessarily result in increased freight volume unless the present potential is more fully exploited and coupled with at least a 30% rate reduction it is unlikely that demand for air freight services within B.C. and on trans-Pacific routes will increase dramatically in the near term. This is particularly true for eastbound traffic, both from Japan and from B.C.; however, advanced technology, lower operating costs through use of larger aircraft, widespread containerization and improved understanding of the implications of an efficient use of air freight in a given distribution system would all appear to augur well for the future of air freight.

description: Emergence of noise induced regularity or Coherence Resonance in nonlinear excitable systems is well known. We explain theoretically why the normalized variance ($V_{N}$) of inter spike time intervals, which is a measure of regularity in such systems, has a unimodal profile. Our semi-analytic treatment of the associated spiking process produces a general yet simple formula for $V_{N}$, which we show is in very good agreement with numerics in two test cases, namely the FitzHugh-Nagumo model and the Chemical Oscillator model.

description: Ved brug af ultralyds baseret måler og video kamera monteret på cykel, er der foretaget 1.374 målinger af passage afstande mellem køretøjer og cyklist. Disse målinger er ud fra video af passager suppleret med oplysninger om køretøj, dets størrelse og fart samt forhold omkring vejens beskaffenhed og den øvrige trafik. Analyse af data viser bl.a., at middelværdien for passage afstand reduceres fra 175 til 135 cm ved modkommende trafik; at pang-farvet cykeljakke reducerer afstand med 10 cm; at afstanden er mindst i eftermiddags myldretid og størst i aftentimer, og at der ikke er forskelle i middelværdier mellem personbiler, varevogne/gulpladebiler, lastbiler og busser. Efterhånden som datagrundlag etableres, udnyttes disse data til at igangsætte en debat og dermed øget fokus om passage afstande. Målet er at gøre bilister mere opmærksomme på at passere med en tryghedsskabende afstand. Samtidig er forventningen også, at dokumentation af, at den faktiske afstand er noget større end den oplevede (alt for tæt på) afstand, kan bruges til at øge tryghedsfølelsen blandt cyklister.

description: Strontium molybdate (SrMoO₃) thin films are grown epitaxially by pulsed laser deposition onto gadolinium scandate (GdScO₃) substrates and characterized in the terahertz (THz) and visible part of the electromagnetic spectrum. X-ray diffraction measurements prove a high crystallinity and phase-pure growth of the thin films. The high-quality SrMoO₃ thin films feature a room temperature DC conductivity of around 3 1/μΩm. SrMoO₃ is characterized in the THz frequency range by time domain spectroscopy. The resulting AC conductivity is in excellent agreement with the DC value. A Lorentz-Drude oscillator approach models the THz and visible conductivity of SrMoO₃ very well. We compare the results of the SrMoO₃ thin films to a standard, sputtered gold film, with a resulting THz conductivity of 8 1/μΩm. The comparison demonstrates that oxide thin film–based devices can play an important role in future THz technology.

description: Organic agriculture is a relatively new production system, which is growing in importance worldwide. As in all enterprises, economic results are important for organic farms. This article aims to determine the economic situation of organic farms against the background of conventional entities on the example of Poland by comparing production potential and relations between production factors, production volume, and the economic results. The analysis was based on the data of the Polish FADN. Since organic farms in Poland are subject to the special EU support, the economic results were presented in two variants, i.e. with and without subsidies for operating activities. Such an approach constitutes an attempt to assess to what extent the two analyzed groups (i.e. organic and conventional farms) can function on the market without public support. The analysis was conducted for two extreme periods, i.e. 2007-2009 and 2016-2018. The first one marks the moment of launching the first Rural Development Programme in Poland for a full seven-year implementation period. The year 2018 provides the latest data available. According to the results, organic farms have lower production potential than conventional farms and less favourable relationships between production factors. Yields and animal productivity are also lower. More importantly, they achieve much lower economic results, which are in large part generated by direct payments. In conclusion, the study showed a high production and income inefficiency of organic farms and their significant dependence on public support.

I 2016 begyndte hjelmbrugen at stige markant igen. Således voksede hjelmbrugen i bytrafik (cyklende på almindelige bygader) signifikant fra 28 % i 2015 til 35 % i 2016, mens hjelmbrugen i skoletrafik (cyklende børn på vej til skole) steg signifikant fra 64 % til 68 %. Brugen af hjelm har aldrig været højere i Danmark. Tallene fra by- og skoletrafik dækker over store aldersmæssige forskelle, da de yngste børn har den højeste hjelmbrug, mens unge har den laveste hjelmbrug.

description: The mechanism by which a patterned state accommodates the breaking of translational symmetry by a phase boundary or a sample wall has been addressed in the context of Landau branching in type-I superconductors, refinement of magnetic domains, and compressed elastic sheets. We explore this issue by studying an ultrathin polymer sheet floating on the surface of a fluid, decorated with a pattern of parallel wrinkles. At the edge of the sheet, this corrugated profile meets the fluid meniscus. Rather than branching of wrinkles into generations of ever-smaller sharp folds, we discover a smooth cascade in which the coarse pattern in the bulk is matched to fine structure at the edge by the continuous introduction of discrete, higher wavenumber Fourier modes. The observed multiscale morphology is controlled by a dimensionless parameter that quantifies the relative strength of the edge forces and the rigidity of the bulk pattern.

description: We establish that in a large class of strongly coupled 3+1 dimensional N=1 quiver conformal field theories with gravity duals, adding a chemical potential for the R-charge leads to the existence of superfluid states in which a chiral primary operator of the schematic form O = λλ+ W condenses. Here λis a gluino and W is the superpotential. Our argument is based on the construction of a consistent truncation of type IIB supergravity that includes a U(1) gauge field and a complex scalar.

description: It is an open question (Pawlikowski) whether every finitely generated group can be realized as a fundamental group of a compact metric space. In this paper we prove that any countable group can be realized as the fundamental group of a compact subspace of four dimensional Euclidean space. According to theorems of Shelah (see also Pawlikowski) such space can not be locally path connected if the group is not finitely generated. This constructions complements realization of groups in the context of compact Hausdorff spaces, that was studied by Keesling and Rudyak, and Przezdziecki .

Fundamental aspects of timber seasoning
Creators: name: Schaffner, RD
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this investigation was to develop an economically viable method of seasoning back-sawn native Tasmanian eucalypts and to reduce the seasoning time required for these timbers. The theory of unsteady state mass transfer based upon Fick's law of diffusion was used to study the drying process. The diffusion coefficients were measured directly by the diffusion cell method or deduced from a comparison of measured and calculated drying curves. The relationship between shrinkage of wood fibre and moisture concentration was obtained by slowly drying thin strips of wood and regularly measuring deformations. The effects of falling diffusivity and shrinkage with reducing moisture concentration were found to effectively cancel one-another in the case of the timbers tested during this investigation. Drying stresses in wood were studied using the theory of elasticity in anisotropic bodies. Airy stress functions were used when solving for stresses. For simplicity, sawn boards were approximated to orthotropic bodies and only boards cut with face-planes parallel/perpendicular to the principle material property directions were studied. Some elastic properties of native Tasmanian eucalypt timbers were measured on small sample populations and found to be similar to those of various North American hardwoods (with similar densities) reported by other authors. The approximate elastic properties of Tasmanian eucalypts were deduced from this comparison. The theories of mass transfer and stress analysis were combined to form a model describing the development of drying stresses. The wood was assumed to be linearly elastic and to be free of the effects of hysteresis and creep. The governing differential equations were solved by numerical methods. The model was used to assess the effectiveness of semi-permeable surface coatings in reducing drying stresses in timber. Tests on timber coated with animal glue (cologen) showed that checking (cracking) in Tasmanian eucalypts brought about by high drying stresses was reduced in severity or completely eliminated, depending upon the thickness of the coating.

description: Manifestly non-Hermitian quantum graphs with real spectra are introduced and shown tractable as a new class of phenomenological models with several appealing descriptive properties. For illustrative purposes, just equilateral star-graphs are considered here in detail, with non-Hermiticities introduced by interactions attached to the vertices. The facilitated feasibility of the analysis of their spectra is achieved via their systematic approximative Runge-Kutta-inspired reduction to star-shaped discrete lattices. The resulting bound-state spectra are found real in a discretization-independent interval of couplings. This conclusion is reinterpreted as the existence of a hidden Hermiticity of our models, i.e., as the standard and manifest Hermiticity of the underlying Hamiltonian in one of less usual, {\em ad hoc} representations ${\cal H}_j$ of the Hilbert space of states in which the inner product is local (at $j=0$) or increasingly nonlocal (at $j=1,2, ...$). Explicit examples of these (of course, Hamiltonian-dependent) hermitizing inner products are offered in closed form. In this way each initial quantum graph is assigned a menu of optional, non-equivalent standard probabilistic interpretations exhibiting a controlled, tunable nonlocality.

Hormone induced spermatogenesis and spermiation in barramundi, Lates calcarifer (Bloch)
Creators: name: Schipp, GR

Year: 2023

description: Between June 1990 and July 1993 a variety of reproductive hormones were tested for their effect on spermiation, spermatogenesis and spawning performance in male barramundi, Lates calcarifer. The study originated from problems experienced with male barramundi spawners during the 1988/89 spawning season. The hormones and dose rates tested in the spermiation experiments were: irradiated carp pituitary extract (iCPE), in 2 intramuscular injections, 24 hours apart, at 8 mg kg\\(^{-1}\\); luteinising hormone releasing hormone analogue (LHRHa, des-Gly\\(^{10}\\)[d-Ala\\(^6\\)]-LH-RH-ethylamide), injected at either 25 or 50 ˜í¬¿g kg\\(^{-1}\\); LHRHa at 25, 50 or 100 ˜í¬¿g kg\\(^{-1}\\) plus pimozide (a dopamine antagonist) at 1.0 mg kg\\(^{-1}\\); Ovaprim SC (A commercial preparation of salmon gonadotrophin releasing hormone analogue and dopamine antagonist) at 0.1 ml kg\\(^{-1}\\); 17˜í¬±, 20˜í‚â§-dihydroxy-4-pregnen-3-one (17˜í¬±-20˜í‚â§P), a progestin steroid at 1.0 mg kg\\(^{-1}\\); and Sustanon '250', a combination of testosterone esters, at 0.5 or 1.0 ml fish\\(^{-1}\\). The results of the spermiation experiments suggest that, LHRHa at 25 ˜í¬¿g kg\\(^{-1}\\), Ovaprim and 17˜í¬±-20˜í‚â§P have the best potential for the development of a hormone therapy for increasing spermiation. Results from the spermiation experiments were tested during actual spawning trials to see if hormone therapy influenced spawning success. It was found that the fish were just as likely to spawn if they had not received hormone treatment. In addition, it was determined that male barramundi do not have to be in running ripe condition prior to addition to the spawning tank. Interaction with the ovulating female appears to be one of the most important factors influencing spawning success. The spermatogenesis experiments examined the effect of chronic hormone therapy over periods longer than one month. In five of the spermatogenesis experiments the fish were implanted with slow releasing cholesterol pellets containing one of the following hormone combinations: 17˜í¬±-methyltestosterone (17-MT), 100, 200 or 400 ˜í¬¿g kg\\(^{-1}\\); LHRHa, 25, 50 or 100 ˜í¬¿g kg\\(^{-1}\\); LHRHa + 17-MT, 25+100, 50+100 or 100+100 ˜í¬¿g kg\\(^{-1}\\). The other experiments examined the implantation of 10 mg of either 17-MT or 19-Norethisterone acetate in silicone pellets and daily, oral administration of 12.5 mg kg\\(^{-1}\\) 17-MT. The experiments were conducted at different times of the year to investigate seasonal response. Of all the hormone treatments tested, only 25 ˜í¬¿g kg\\(^{-1}\\) LHRHa pellets showed any real potential and only during the peak breeding season. Based on these trials it is not possible to develop a protocol, using hormone therapy that reliably enhances the breeding condition of male barramundi. Recent success overseas and in Queensland with environmental control of barramundi breeding provides the best means for control of reproduction.

description: Since the opaqueness of algorithms used for rankings, recommender systems, personalized advertisements, and content moderation on online platforms opens the door to discriminatory and anti-competitive behavior, increasing transparency has become a key objective of EU lawmakers. In the latest Commission proposals, the Digital Markets Act and Digital Services Act, transparency obligations for online intermediaries, platforms and ‘gatekeepers’ figure prominently. This paper investigates whether key concepts of competition law and transparency on digital markets are used in the same way by different stakeholders. Leveraging the power of computational text analysis, we find significant differences in the employment of terms like ‘gatekeepers’, ‘simple’, and ‘precise’ in the position papers that informed the drafting of the two latest Commission proposals. This finding is not only informative for the Commission and legal scholars, it might also affect the effectiveness of transparency duties, for which it is often simply assumed that phrases like ‘precise information’ are understood the same way by those implementing said obligations. Hence, it may explain why they fail so often to reach their goal. We conclude by sketching out how different computational text analysis tools, like topic modeling, sentiment analysis and text similarity, could be combined to provide many helpful insights for both rulemakers and the legal scholarship.

The corrections to the Coulomb interaction of quantum well electrons induced by the spin-orbit coupling are derived. The developed theory is applied to calculate the energy spectrum fine structure of an electron pair triplet states localized in small lateral disk-shaped quantum dots. We show that the spin degeneracy of a triplet state is completely lifted in anisotropic quantum dots. Isotropic quantum dots also demonstrate peculiar fine structure of triplet states caused by the spin-orbit interaction.

The critical temperature, as well as the critical point exponents are obtained. For the undi- rected case this random system belongs to the same universality class as the regular two-dimensional model. However, for the directed random lattice one has a second-order phase transition for q < qc and a first-order phase transition for q > qc, where qc is the critical rewiring probability. The critical exponents for q < qc was calculated and they do not belong to the same universality class as the regular two-dimensional ferromagnetic model.

Year: 2022

description: Wastewater analysis and surveillance are well-established practices whose use has dramatically expanded during the COVID-19 pandemic. In this article, we argue that the extraction of diverse types of data from wastewater is part of the larger phenomenon of ‘datafication’. We explore the evolving technologies and uses of wastewater data and argue that there are insufficient legal and ethical frameworks in place to properly govern them. We begin with an overview of the different pur- poses for wastewater data analyses as well as the location and scale of collection. We then consider legal and ethical principles and oversight frameworks that shape current approaches to wastewater collection. After situating wastewater collection within its particular civic context, we argue in favour of greater engagement with legal and ethical issues and propose doing so through a civic perspective. Our paper concludes with a discussion of the normative shifts that are needed and how we might achieve these.

description: We have computed a spherically symmetric model for the interaction of matter ejected during the outburst of a classical nova with the stellar wind from its optical component.This model is used to describe the intense X-ray outburst (the peak 3-20 keV flux was ~2 Crab) of the binary system CI Camelopardalis in 1998. According to our model, the stellar wind from the optical component heated by a strong shock wave produced when matter is ejected from the white dwarf as the result of a thermonuclear explosion on its surface is the emission source in the standard X-ray band. Comparison of the calculated and observed time dependences of the mean radiation temperature and luminosity of the binary system during its outburst has yielded very important characteristics of the explosion.We have been able to measure the velocity of the ejected matter immediately after the onset of the explosion for the first time: it follows from our model that the ejected matter had a velocity of ~2700 km/s even on 0.1-0.5 day after the outburst onset and it flew with such a velocity for the first 1-1.5 day under an external force, possibly, the radiation pressure from the white dwarf. Subsequently, the matter probably became transparent and began to decelerate. The time dependence of the mean radiation temperature at late expansion phases has allowed us to estimate the mass of the ejected matter, ~10^{-7}-10^{-6} Msun. The mass loss rate in the stellar wind required to explain the observed peak luminosity of the binary system during its outburst has been estimated to be dM/dt ~(1-2)x10^{-6} Msun/yr.

description: With the rapid development of mobile devices and the fast increase of sensitive data, secure and convenient mobile authentication technologies are desired. Except for traditional passwords, many mobile devices have biometric-based authentication methods (e.g., fingerprint, voiceprint, and face recognition), but they are vulnerable to spoofing attacks. To solve this problem, we study new biometric features which are based on the dental occlusion and find that the bone-conducted sound of dental occlusion collected in binaural canals contains unique features of individual bones and teeth. Motivated by this, we propose a novel authentication system, TeethPass+, which uses earbuds to collect occlusal sounds in binaural canals to achieve authentication. First, we design an event detection method based on spectrum variance to detect bone-conducted sounds. Then, we analyze the time-frequency domain of the sounds to filter out motion noises and extract unique features of users from four aspects: teeth structure, bone structure, occlusal location, and occlusal sound. Finally, we train a Triplet network to construct the user template, which is used to complete authentication. Through extensive experiments including 53 volunteers, the performance of TeethPass+ in different environments is verified. TeethPass+ achieves an accuracy of 98.6% and resists 99.7% of spoofing attacks.

Land development in the 1970’s
Creators: name: Peterson, William Scott
Publisher: name: University of British Columbia
Year: 2010

description: Land use control, and consequently the process of land development, have undergone major modifications within the last few years. Conventional land use controls, such as zoning by-laws and subdivision regulations, have been reformed for various "observable" and "non-observable" reasons to include such devices as comprehensive zoning, planned unit developments and land use contracts. As a result, land developers have had to adjust their operational responsibilities, In this paper, we a re primarily concerned with the possible reasons for the recent shifts evident within contemporary land use legislation; and the subsequential reactions by land developers. A review of the literature concerned with contemporary land use controls and their impacts will be utilized. Traditional land economic theory will supplement these observations. It is hoped that this study will encourage further examination of the land development environment observed in this present impirical analysis. The main objectives might hopefully be to stimulate thought, provoke discussion and encourage further work in the field.

description: We present the results of our study of the long-period eclipsing binary star \Aur. The results are based on spectroscopic data obtained with the UFES échelle spectrograph and photometric observations from TESS. The derived radial velocity curve is based on 17 spectra obtained between 2021 and 2023, covering all orbital phases of this binary system. The orbital period determined from TESS data, $P = 27.019803 \pm 0.000003$ days, agrees within uncertainties with the period established in previous studies. The model constructed for the TESS photometric light curve achieves a precision of 0.01\%. The effective temperatures of both components, as well as the system metallicity, were directly derived from the spectra and are $T_\mathrm{eff, A} = 6250 \pm 50$\,K, $T_\mathrm{eff, B} = 5855 \pm 50$\,K, and $\mathrm{[Fe/H]} = -0.10 \pm 0.08$, respectively. Our analysis of the photometric and spectroscopic data allowed us to directly compute the luminosities of the components, $L_A = 1.82\,L_\odot$ and $L_B = 1.07\,L_\odot$, their radii, $R_A = 1.15\,R_\odot$ and $R_B = 1.00\,R_\odot$, and their masses, $M_A = 1.137\,M_\odot$ and $M_B = 1.023\,M_\odot$, with uncertainties below 1\%. Comparison with evolutionary tracks indicates that the system's age is $1.18 \pm 0.10$\,Gyr, and both components are still on the main sequence. The \Aur\ system is particularly interesting due to the partial eclipse of the primary component, which results in the ``inversion'' of the primary and secondary minima in the photometric light curve.

description: The idea of the divided milking machine or 4-way system as it is now called, was first conceived quite some time ago, but the first prototypes have only been milking in field trial dairies for approximately the last two years. The primary purpose of the 4-way milk system is to prevent cross-infection from one quarter to another on the same cow. The 4-way milk system can be a valuable tool in a dairy herd health practice when implemented in a mastitis control program along with good management, cleanliness of housing areas, good sanitation, proper milking procedure and properly functioning milking equipment.

description: Nowadays, mobile smart devices are widely used in daily life. It is increasingly important to prevent malicious users from accessing private data, thus a secure and convenient authentication method is urgently needed. Compared with common one-off authentication (e.g., password, face recognition, and fingerprint), continuous authentication can provide constant privacy protection. However, most studies are based on behavioral features and vulnerable to spoofing attacks. To solve this problem, we study the unique influence of sliding fingers on active vibration signals, and further propose an authentication system, FingerSlid, which uses vibration motors and accelerometers in mobile devices to sense biometric features of sliding fingers to achieve behavior-independent continuous authentication. First, we design two kinds of active vibration signals and propose a novel signal generation mechanism to improve the anti-attack ability of FingerSlid. Then, we extract different biometric features from the received two kinds of signals, and eliminate the influence of behavioral features in biometric features using a carefully designed Triplet network. Last, user authentication is performed by using the generated behavior-independent biometric features. FingerSlid is evaluated through a large number of experiments under different scenarios, and it achieves an average accuracy of 95.4% and can resist 99.5% of attacks.

description: Prostaglandin F2a (PGF2a) has been reported to be luteolytic in the bovine. As a result of the luteolytic activity, PG F2a has been reported in both scientific and clinical journals to be effective in cattle for treatment of unobserved estrus, abortion, parturition, pyometra, termination of pathological gestation and cystic ovaries. The data support a conclusion that Lutalyse sterile solution was effective for the treatment of unobserved (silent) estrus as measured by pregnancy rates within five (5) days after treatment.

description: Veterinary services to the food animal industries are in a period of important adjustments, if not crisis, induced in part by the long-term success of veterinary science in reducing exotic diseases and by competition from other inputs. While control of exotic diseases and competition from other inputs have reduced the demand for food animal services, the supply of veterinarians to industry has been diminished by a growing demand for companion animal veterinarians as consumer incomes have increased.

Aspects of the inorganic amorphous system of humo ferric podzols of the Lower Main Land [sic] of British Columbia.
Creators: name: Visentin, Girolamo
Publisher: name: University of British Columbia
Year: 2010

description: A study was made to: ( i ) investigate the nature and the structural organization of the inorganic amorphous system in podzol soils of British Columbia, (ii) evaluate the relationships between this natural system and artificial amorphous iron-aluminosilicate systems. Results of this study are described in a series of three papers, each describing phases of this study. The successive selective dissolution analysis, combined with infrared spectroscopy technique proved to be suitable for qualitative as well as quantitative determination of the inorganic amorphous system of the soils studied. A structural model for artifical amorphous iron-aluminosilicate systems is discussed and although not considered to be perfect, presents a useful picture of iron-aluminosilicate structures as it offers an explanation for some of the experimental findings recorded. Strong correlations have been found through chemical and physical analyses between the amorphous inorganic system of the soils studied and artificially-prepared iron-aluminosilicate systems, and close structural organization between the two systems is inferred.
The Relationship of Environment to Respiratory Disease in the Dairy Calf

description: Veterinarians have diagnosed enteric and pneumonic diseases in cattle for many decades. Causative organisms have been isolated on numerous occasions. Histopathological studies reveal typical lesions associated with specific organisms. Antibiotic sensitivities are conducted and treatment is now routinely instituted on the basis of sensitivity tests. Vaccines are produced against specific viruses and / or bacteria. Regimes for treatment have been offered. However, in spite of our best efforts as professionals many diseases continue practically unabated. Evidence for this conclusion is drawn from the yearly mortality rate in dairy calves of 8-25% in the United States (Agriculture Statistics 1980).

description: In the context of quantum gravity, group field theories are field theories that generate spinfoam amplitudes as Feynman diagrams. They can be understood as generalizations of the matrix models used for 2d quantum gravity. In particular Boulatov's theory reproduces the amplitudes of the Ponzano-Regge spinfoam model for 3d quantum gravity. Motivated by recent works on field theories on non-commutative flat spaces, we show that Boulatov's theory (and its colored version) is actually invariant under a global deformed Poincare symmetry. This allows to define a notion of flat/excited geometry states when considering scalar perturbations around classical solutions of the group field equations of motion. As a side-result, our analysis seems to point out that the notion of braiding of group field theories should be a key feature to study further in this context.

An Efficient and Safe Method of Castration for the Bovine By the Intra-Testicular Injection of Chem-Cast
Creators: name: Miller, R. E.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1982

description: The practice of castration, effecting elimination of the testes and reducing libido or virility, has for centuries been carried out in various ways. The method used has been largely dependent on the species, the opportunity to observe the animal following castration, and the nature of local disease problems. Such diseases as tetanus, black leg, malignant edema, and the presence of the screw worm fly may cause severe problems following castration by methods which result in an open wound or abrasion.
