Resolving a taxonomic ambiguity : variation in the pycnogonid Pseudopallene ambigua (Stock 1956)
Creators: name: Stevenson, DG
Publisher: name: University Of Tasmania
Year: 2023

description: A combination of molecular and morphological techniques was applied to resolve a nearly 50-year-old ambiguity in the Australian pycnogonid Pseudopallene ambigua (Stock 1956). Stock was hesitant to initially describe P. ambigua due to confusion with a sister species P. pachychiera. More recent work has clarified the distinction between these taxa but P. ambigua remains enigmatic with the type series suspected to contain several species. For this study, P. ambigua were collected from a 10-11 kilometre section of the Tasmanian east coast around Eaglehawk Neck, SE Tasmania. The 56 specimens of P. ambigua were examined and the data used to generate morphological groups within this species. Samples from these morphological groups were then sequenced at two rapidly evolving gene regions, the mitochondrial 16S ribosomal gene and the mitochondrial cytochrome c oxidase I protein coding gene. Comparison of the sequence data for both 16S and cytochrome c oxidase determined that two species were present in this collection. These genetically identified species were consistent with the morphological data. Morphological characters including proboscis shape, oviger spine number, tibiae surface texture, heel spine pattern and propodus width-height ratio were found to confirm the molecular 16S and COl sequences separating a consistent group of specimens. Examination of the morphological data provided significant evidence for the characters proboscis shape and propodus ratio that will enable the new species to be readily identified from P. ambigua.

description: We carry out a gauge invariant analysis of certain perturbations of $D-2$-branes solutions of low energy string theories. We get generically a system of second order coupled differential equations, and show that only in very particular cases it is possible to reduce it to just one differential equation. Later, we apply it to a multi-parameter, generically singular family of constant dilaton solutions of non-critical string theories in $D$ dimensions, a generalization of that recently found in arXiv:0709.0471[hep-th]. According to arguments coming from the holographic gauge theory-gravity correspondence, and at least in some region of the parameters space, we obtain glue-ball spectra of Yang-Mills theories in diverse dimensions, putting special emphasis in the scalar metric perturbations not considered previously in the literature in the non critical setup. We compare our numerical results to those studied previously and to lattice results, finding qualitative and in some cases, tuning properly the parameters, quantitative agreement. These results seem to show some kind of universality of the models, as well as an irrelevance of the singular character of the solutions. We also develop the analysis for the T-dual, non trivial dilaton family of solutions, showing perfect agreement between them.

description: Rotaviruses frequently are found in cases of calf diarrheas submitted to the veterinary diagnostic laboratories in the State of Nebraska. This report involves case investigations of two ranches located in Western Nebraska, USA, that experienced morbidity and mortality associated with severe enteritis in neonatal calves. The investigations and results presented here reflect the procedures performed to reach applicable diagnostic conclusions. Investigations of field cases, such as these, do not always allow unlimited study, yet still provide valuable scientific data which can shed some light on a complex syndrome such as neonatal calf diarrhea.

Nucleic acid metabolism of a estrogen dependent adrenal cortical tumor
Creators: name: Redman, Lyle Wharton
Publisher: name: University of British Columbia
Year: 2011

description: The work in this thesis consisted of initial experiments designed to elucidate the role of hormones in a hormonal dependent tumor. Various aspects of nucleic acid synthesis in a hormone dependent tumor in the presence (growing) and absence (regressing) of the hormone were studied. The rates of nucleic acid synthesis were studied in whole animals by injecting radioactive formate and allowing the animal to incorporate radioactivity for various periods of time. Nucleic acids were extracted by PAS, phenol procedure and separated on a MAK column. Labelling of all species of nucleic acid was decreased in regressing tumors. In order to determine whether estrogen is acting directly on cells or at some indirect physiological level; the ability of cells from growing and regressing tumor to synthesize nucleic acids in vitro was determined. Results of experiments with these cell suspensions demonstrate that cells from the regressing tumor had a decreased ability to synthesize nucleic acids relative to growing tumor. The rate of DNA synthesis was decreased somewhat more than RNA. In preliminary experiments the activity of DNA dependent DNA polymerase and RNA polymerase from regressing tumor was compared with the same enzyme in growing tumor. The specific activity of both RNA and DNA polymerase was decreased in the regressing tumor. In target tissue like uterus stimulation with estradiol results in an increased rate of synthesis of several species of RNA. In the tumor system used in these preliminary experiments, stimulation with estrogens has a greater effect on the synthesis of DNA than RNA.

description: Time constants for photodetachment, photoemission, and electron capture are considered for two classes of mesospheric aerosol particles, i.e., meteor smoke particles (MSPs) and pure water ice particles. Assuming that MSPs consist of metal oxides like Fe2O3 or SiO, we find that during daytime conditions photodetachment by solar photons is up to 4 orders of magnitude faster than electron attachment such that MSPs cannot be negatively charged in the presence of sunlight. Rather, even photoemission can compete with electron capture unless the electron density becomes very large (≫1000 cm-3) such that MSPs should either be positively charged or neutral in the case of large electron densities. For pure water ice particles, however, both photodetachment and photoemission are negligible due to the wavelength characteristics of its absorption cross section and because the flux of solar photons has already dropped significantly at such short wavelengths. This means that water ice particles should normally be negatively charged. Hence, our results can readily explain the repeated observation of the coexistence of positive and negative aerosol particles in the polar summer mesopause, i.e., small MSPs should be positively charged and ice particles should be negatively charged. These results have further important implications for our understanding of the nucleation of mesospheric ice particles as well as for the interpretation of incoherent scatter radar observations of MSPs. © 2009 Author(s).

In particular, we analyse the quiver matrix models recently introduced by Dijkgraaf and Vafa and make detailed comparisons with the corresponding quantities in the Toda field theories and the N=2 quiver gauge theories. We also make a speculative proposal for how the matrix models should be modified in order for them to reproduce the instanton partition functions in quiver gauge theories in five dimensions.

description: A fast and simple assay with high sensitivity to BVDV in blood samples independent of blood storage and clinical status of animals. is described. A pan-pesti virus reactive monoclonal antibody Cl6 (BVDV-p 80/125 specific) was applied for immunofluorescence (IF) in flow cytometry with leukocytes and for IF with infected bovine kidney cells as a reference method. From 304 blood samples of patients of the veterinary clinic 63 NCP- and 7 CP- BVDV strains were isolated. There is a high BVDVspecific IF in granulocytes and monocytes, whereas in lymphocytes the IF intensity per cell is weaker. The percentage of antigen positve cells varies from 1% to 87 % (mean 22%) in granulocytes/monocytes and 0% to 37% (mean 8%) in lymphocytes. There is a total correlation between conventional BVDV-diagnosis with tissue culture isolation and leukocyte analysis with flow cytometry. After blood freezing or storage at +8°C for 6 weeks BVDV detection in leukocytes is not significantly influenced. Flow cytometry provides a quantitative, objective analysis of leukocyte associated BVDV-antigen. Both low levels of antigen per cell and low percentages of antigen positive cells are detectable. Direct leukocyte analysis with flow cytometry is a rapid (2 hours). easy and reliable method for detection of viremic cattle.

description: We prove that some Riemannian manifolds with boundary under an explicit integral pinching are spherical space forms. Precisely, we show that 3-dimensional Riemannian manifolds with totally geodesic boundary, positive scalar curvature and an explicit integral pinching between the $L^2$-norm of their scalar curvature and the $L^2$-norm of their Ricci tensor are spherical space forms with totally geodesic boundary. Moreover, we prove also that 4-dimensional Riemannian manifolds with umbilic boundary, positive Yamabe invariant and an explicit integral pinching between the total integral of their $(Q,T)$-curvature and the $L^2$-norm of their Weyl curvature are spherical space forms with totally geodesic boundary. As a consequence of our work, we show that a certain conformally invariant operator which plays an important role in Conformal Geometry has a trivial kernel and is non-negative if the Yamabe invariant is positive and verifies a pinching condition together with the total integral of the $(Q,T)$-curvature. As an application of the latter spectral analysis, we show the existence of conformal metrics with constant $Q$-curvature, constant $T$-curvature, and zero mean curvature under the latter assumptions.

description: We systematically investigate the formation and stability of snowballs formed by femtosecond photo-ionization of small alkali clusters bound to helium nanodroplets. For all studied alkali species Ak=(Na, K, Rb, Cs) we observe the formation of snowballs (AkHe_N)^+ when multiply doping the droplets. Fragmentation of clusters Ak_N upon ionization appears to enhance snowball formation. In the case of Na and Cs we also detect snowballs (Ak_2He_N)^+ formed around Ak dimer ions. While the snowball progression for Na and K is limited to less than 11 helium atoms, the heavier atoms Rb and Cs feature wide distributions at least up to (AkHe_41)^+. Characteristic steps in the mass spectra of Cs-doped helium droplets are found at positions consistent with predictions on the closure of the 1st shell of helium atoms around the Ak^+ ion based on variational Monte Carlo simulations.

description: Five cattle were twice vaccinated. The interval between the vaccinations was 28 days. Five cattle served as non-vaccinated controls. 348 days after the first vaccination, one non-vaccinated control animal was intranasally challenged with 5 .105 TCID50 of virulent BHV1 virus. It served as contact excreter animal for all the other non vaccinated controls and the vaccinates. After challenge, the following treatments were performed: - three previously vaccinated animal, and two non-vaccinated controls received one dose of vaccine at day D 390 and day D 411 after challenge while the remaining five animals did not. - all the animals were treated with dexamethazone during 5 days at day D 455 after challenge (I.V. 1st day, I.M. 4 days). Vaccination significantly reduced virus excretion and clinical signs after challenge. Some of the vaccinated animals (vaccination before challenge) were protected against recrudescence after dexamethazone treatment. Detailed results will be presented and discussed in the context of control of BHV1.

Facies Architecture of the Volcanic Sedimentary Complex of the Iberian Pyrite Belt, Portugal and Spain
Creators: name: Rosa, CJP
Publisher: name: University Of Tasmania
Year: 2023

description: The Iberian Pyrite Belt is the richest massive sulfide province in the world. The massive sulfide ore deposits occur in a felsic volcanic and sedimentary succession (VS Complex) of late Famennian (Upper Devonian) to late Visean (Middle Carboniferous) age. Volcanic facies analysis has been carried out on three areas in Portugal, including the Neves Corvo mine, and five sections in Spain. In all sections studied, the depositional setting during accumulation of the VS Complex was submarine and below wave base. The principal felsic volcanic facies are: (1) coherent rhyolite and dacite, associated with monomictic breccia; (2) fiamme-rich breccia (with variable amounts of dense volcanic and sedimentary clasts), fiamme-rich sandstone and fiamme-bearing mudstone; and (3) crystal-rich sandstone and mudstone. Mafic units are minor, dominated by coherent facies and have uncertain mode of emplacement (intrusions or lavas). Fiamme typically have lenticular shape and quartz- or quartz- and feldspar-phyric texture, and are interpreted to be altered and compacted pumice clasts. The volcanic facies are typically interleaved with, and regionally less voluminous than, the non-volcanic facies, which are dominated by mudstone. The felsic volcanic facies are interpreted to be the products of numerous, relatively small intrabasinal volcanic centres that generated abundant lavas, domes and pyroclastic units. Some volcanic centres are dominated by lavas, whereas others have similar proportions of lavas and pyroclastic units. The domes and lavas are more voluminous but less laterally extensive than the pyroclastic units. A sediment-matrix breccia typically occurs at the top contact of the felsic lavas with sedimentary units. This sediment-matrix breccia formed from the infiltration of fine sediment into interclast spaces in previously formed hyaloclastite, and could be misinterpreted as peperite. Felsic intrusions are less voluminous than lavas, and were emplaced as cryptodomes and partly extrusive cryptodomes, late in the evolution of the VS Complex. The architecture of the different study areas reflects differences in the eruption style, emplacement processes and proximity to source. Parts of the succession interpreted to be proximal are dominated by thick lavas/domes and intrusions, and coarse pyroclastic deposits. Medial parts comprise resedimented autoclastic facies derived from the lavas and domes, and relatively thin pyroclastic units. Distal parts comprise relatively thinly bedded crystal-rich sandstone and siliceous mudstone. Regional correlations in the VS Complex are impossible, as none of the volcanic facies are regionally extensive and each of the volcanic centres has a unique internal architecture. At Neves Corvo mine, the massive sulfide ore deposits are close to one of the felsic volcanic centre(s), occurring immediately above the rhyolitic lavas/domes. IV

description: We present AGN from the Sloan Digital Sky Survey (SDSS) having double-peaked profiles of [OIII] 5007,4959 and other narrow emission-lines, motivated by the prospect of finding candidate binary AGN. These objects were identified by means of a visual examination of 21,592 quasars at z < 0.7 in SDSS Data Release 7 (DR7). Of the spectra with adequate signal-to-noise, 148 spectra exhibit a double-peaked [OIII] profile. Of these, 86 are Type 1 AGN and 62 are Type 2 AGN. Only two give the appearance of possibly being optically resolved double AGN in the SDSS images, but many show close companions or signs of recent interaction. Radio-detected quasars are three times more likely to exhibit a double-peaked [OIII] profile than quasars with no detected radio flux, suggesting a role for jet interactions in producing the double-peaked profiles. Of the 66 broad line (Type 1) AGN that are undetected in the FIRST survey, 0.9% show double peaked [OIII] profiles. We discuss statistical tests of the nature of the double-peaked objects. Further study is needed to determine which of them are binary AGN rather than disturbed narrow line regions, and how many additional binaries may remain undetected because of insufficient line-of-sight velocity splitting. Previous studies indicate that 0.1% of SDSS quasars are spatially resolved binaries, with typical spacings of ~10 to 100 kpc. If a substantial fraction of the double-peaked objects are indeed binaries, then our results imply that binaries occur more frequently at smaller separations (< 10 kpc). This suggests that simultaneous fueling of both black holes is more common as the binary orbit decays through these spacings.

description: Acute pneumonia is an economically important disease afflicting young cattle world-wide. The disease develops as a complex interaction and the aetiology of any outbreak is often multifactorial (1). Pasteurella spp. are the most important bacteria involved causing fibrinous bronchopneumonia (2, 3), but more frequently they increase the severity of lung lesions inflicted by viruses and/or mycoplasmas. Transport, housing and mixing of animals are management factors contributing to outbreaks of acute pneumonia. This paper summarizes the results of seven studies conducted in Europe in which the efficacy of the fluoroquinolone antimicrobial danofloxacin* against naturally occurring outbreaks of acute pneumonia in calves was evaluated in comparison with trimethoprim/sulpha.

description: Several studies have tried to ascertain whether or not the increase in abundance of the early-type galaxies (E-S0a's) with time is mainly due to major mergers, reaching opposite conclusions. We have tested it directly through semi-analytical modelling, by studying how the massive early-type galaxies with log(M_*/Msun)>11 at z~0 (mETGs) would have evolved backwards-in-time, under the hypothesis that each major merger gives place to an early-type galaxy. The study was carried out just considering the major mergers strictly reported by observations at each redshift, and assuming that gas-rich major mergers experience transitory phases of dust-reddened, star-forming galaxies (DSFs). The model is able to reproduce the observed evolution of the galaxy LFs at z

El Salvador

description: A currency's essential feature is to be a medium of exchange. We leverage a quasi-natural experiment––El Salvador as the first country to make Bitcoin legal tender––to study a cryptocurrency's potential to be used in daily transactions. The government also launched and provided incentives to download and use a digital wallet named Chivo, which shares features with Central Bank Digital Currencies (CBDCs) and allows users to trade bitcoins and dollars. Were Chivo Wallet and Bitcoin actually adopted after this "big push"? Conducting a representative face-to-face survey and relying on blockchain data to obtain all Chivo transactions, we document how usage of digital payments and Bitcoin is low, concentrated, and has been decreasing over time. We find that privacy concerns are key barriers to adoption, which speaks to a policy debate on crypto and CBDCs that has had anonymity at its core. We also estimate the technology's adoption cost and its network externalities.

description: After randomization, 18 calves were inoculated with a Pha1 isolate as described in an earlier protocol. After the first inoculation 6 calves received Ceftiofur (CEF), 1 mg/kg by intramuscular route (IM) every day for 5 days together with methyl-prednisolone-succinate (MPS) 3 mg/kg IM on two consecutive days, 6 calves received CEF + an MPS placebo, and 6 calves a CEF placebo+ an MPS placebo. Twice a day before the meal all calves were clinically examined to determine a mean disease score (MOS). After their death or sacrifice, 7 days at most after the first inoculation, all calves were autopsied. The lungs were weighed, the extent of the lesions quantified by a score (mean lung score= MLS) based on combined inspection and palpation and a quantitative bacteriological examination carried out on the damaged lung parenchyma. The validity of the model was confirmed by the percentage mortality observed in the control group (83 % versus 17 % in the other groups). A similar trend was apparent in the clinical results (significant difference p ≤ 0,05 between the mean MOS of the control group and that of the other group) in the necropsy results (significant difference p ≤ 0,05 between the control group and the other groups for mean lung weight and MLS)) and in the microbiological results (significant difference p ≤ 0,05 between the mean number of cfu Pha1/g of lung in the control group and other groups). This demonstrate the efficacy of both therapeutic regimens (i.e. CEF and CEF + MPS) in our model. The advantage of the antibiotic + steroidal anti-inflammatory treatment is not clear.

description: Enzootic calf pneumonia (ECP) is one clinical manifestation of the bovine respiratory disease complex. Enzootic calf pneumonia results from a complex interaction between environmental factors, host factors, and infectious agents. The financial losses that result from ECP occur due to death loss, treatment cost, and decreased lifetime milk production. Calves that have experienced ECP have been shown to be at increased risk of culling once in the milking herd when compared to herdmates of the same age(1). Experimental studies involving the infectious agents themselves have been performed(2-9), as well as retrospective(10-16) and cohort studies(17-22). None of the current epidemiologic research has specifically targeted ECP, either through assessment of ventilation or laboratory sampling to validate morbidity or mortality.

description: The effect of experimentally-induced pneumonia on diaphragmatic strength generation was studied in spontaneously breathing calves. Five healthy male Friesian calves, 7 to 15 days old and weighing 44.5 ± 1.9 kg (mean± SE) were exposed to intratracheal instillation of 30 ml Pasteurella hemolityca Al broth (5.10 9 to 5.101° CFU/ml) in logarithmic phase of growth. The diaphragm was electrically stimulated via intracaval platinum electrodes mounted on a 12-gauge catheter introduced in the right jugular vein. The transdiaphragmatic pressure (Pdi) generated at functional residual capacity against occluded airways during supramaximal (60 V) 2-sec stimulations applied over a frequency range of 10-100 Hz was measured using conventional balloon catheters systems. The procedure was repeated before, 3, 6 and 9 hours after inoculation. Full article in French, English and German summaries in PDF.

Meiosis and pollen fertility in Prunus avium L. cv. Lambert and irradiation propagates of Lambert
Creators: name: Whelan, Ernest David Pratt
Publisher: name: University of British Columbia

description: The meiotic behaviour and pollen fertility of Lambert sweet cherry (Prunus avium L.) and irradiation propagates of Lambert were investigated. Chromosome clumping, due to associations between the centromere region of non-homologous chromosomes, characterized early meiotic stages in Lambert. While the associations, which were evident as chromatic centers, complicated interpretation of pachynema, the pachytene morphology of the eight chromosomes was described. Except for small chromatic areas delimiting the centromere, all chromosomes were basically achromatic. Three chromosomes had an additional one or two chromatic regions, which in all cases were in the short arm. One chromosome, designated number 3, had a major heterozygous interstitial deletion in the short arm. Marked repulsion between the homologous chromosomes during diplonema resulted in a diffuse stage. The single pair of univalents, occasionally observed throughout meiosis and considered to be of desynaptic origin, were first detected in diplonema. Subsequent meiotic stages were usually normal, and the incidence of abnormal meiosis and tetrad stages containing micronuclei were estimated to be 9-62 per cent and 3.24 per cent respectively. Meiosis was characterized by synchronous division within the anther locules. Cytoplasmic connections were evident between neighbouring meiocytes during meiosis I, and cytomictic phenomena were observed occasionally. Abortion of 50 per cent of the developing microspores occurred prior to the first mitotic division of the spore nucleus, and was attributed to the heterozygous deletion in chromosome 3. Pollen abortion at anthesis was estimated to be about 42 per cent. Annual or regional effects on the incidence of abnormal meiosis or pollen abortion were not evident. Forcing of blossom buds at 15°C did not appear to affect meiotic behaviour. Twelve irradiation propagates of Lambert were investigated. Of these, seven had pollen fertility similar to the parental Lambert clone, and their meiotic behaviour also was comparable. The remaining five propagates had reduced pollen fertility. One propagate was found to have a greatly increased incidence of the single pair of univalents, as compared to parental Lambert; two propagates contained a reciprocal translocation; and two contained a paracentric inversion. The extent of pollen abortion was predictable from the meiotic behaviour in only one of the latter five propagates. Pollen studies revealed significant annual variation among the 12 irradiation propagates, some varying more than others. With one exception, forcing of blossom buds at 15°C did not appear to affect meiotic behaviour.

description: In this paper, we address the issue of the stability of the thermal equilibrium of large quantum systems with respect to variations of the thermal contact between them. We study the Schrödinger time evolution of a free bosonic field in two coupled one-dimensional cavities after a sudden change of the contact between the cavities. Though the coupling we consider is thermodynamically small, modifying it has a considerable impact on the two-point correlation functions of the system. We find that they do not return to equilibrium but essentially oscillate with a period proportional to the length of the cavities. We compare this coupled cavities system with the perfect gas which is described by similar expressions but behaves very differently.

description: Acute bovine respiratory diseases (ABRD) are the most important cause of sanitary economic losses in cattle. These problems are increasing despite the use of preventive and therapeutic agents. This could be due to several factors like increase of the population density in the cattle units, increase of the virulence of the pathogens, increase of air pollution, etc. Another explanation could be that, in the past, bovine respiratory diseases have been analysed at a pathological but not functional level. In the light of new information on bovine pulmonary function in health and disease, it appears that, before the occurrence of irreversible and of course untreatable lung damages, there are some reversible dysfunctions at the level of pulmonary ventilation, perfusion or gas diffusion. An early and appropriate correction of these dysfunctions is of a critical importance in order to decrease the rate of mortality and chronic pneumonia. The purpose of this paper is to analyse the pecularities of the bovine pulmonary physiology and pathophysiology in order to try to improve the efficiency of the treatment of ABRD. The prevention of ABRD, although highly important, is not analysed in this paper.

description: On 2009 June 5, the Gamma-ray Burst Monitor (GBM) onboard the Fermi Gamma-ray Space Telescope triggered on two short, and relatively dim bursts with spectral properties similar to Soft Gamma Repeater (SGR) bursts. Independent localizations of the bursts by triangulation with the Konus-RF and with the Swift satellite, confirmed their origin from the same, previously unknown, source. The subsequent discovery of X-ray pulsations with the Rossi X-ray Timing Explorer (RXTE), confirmed the magnetar nature of the new source, SGR J0418+5729. We describe here the Fermi/GBM observations, the discovery and the localization of this new SGR, and our infrared and Chandra X-ray observations. We also present a detailed temporal and spectral study of the two GBM bursts. SGR J0418+5729 is the second source discovered in the same region of the sky in the last year, the other one being SGR J0501+4516. Both sources lie in the direction of the galactic anti-center and presumably at the nearby distance of ~2 kpc (assuming they reside in the Perseus arm of our galaxy). The near-threshold GBM detection of bursts from SGR J0418+5729 suggests that there may be more such dim SGRs throughout our galaxy, possibly exceeding the population of bright SGRs. Finally, using sample statistics, we conclude that the implications of the new SGR discovery on the number of observable active magnetars in our galaxy at any given time is <10, in agreement with our earlier estimates.

description: Since HOFLUND's explanation (1) of a functional stenosis of either the bovine forestomach or the pylorus due to damages of the vagal nerve in 1940, this hypothesis is discussed controversially. In addition disturbances of the beforementioned extrinsic nerve system, mechanical influences are discussed to be the origin of this disease (2,3). As an extrinsic control system the vagal nerves are responsible for a coordionated contraction of the ruminant forestomach. These nerves originating from the gastric centre in the medulla oblongata are consisting of predominantly afferent fibres and some efferent, preganglionic nerve fibres ( 4). The efferent fibres are communicating with intramurally located ganglia. Recently published data present that the intramural neurons, also named as intrinsic nerve system are able to initiate reticulo-ruminal contraction (9,10). Purpose of this study was to evaluate morphological alterations of vagal and intramural nerve fibres, intramural neurons and inflamamtory changes in the wall of the forestomachs and abomasum of cows suffering from HOFLUND's Syndrome.

description: PROBLEMS WITH ORAL REHYDRATION THERAPY AND FORCE-FEEDING IN THE YOUNG CALF The introduction of oral glucose-electrolyte solutions (ORS) in the rehydration therapy in calf diarrhea is believed to be one of the most important advances in veterinary medicine in the past decades. However, own experiences and investigations with several hundred neonatal calves suffering from diarrhea or other diseases show that the use of such solutions - including so-called 'diet-drinks' - implies various risks, which have to be considered.

title: Origins, articulations and continuities in foreign policy and foreign policy formation: the case of civilian and military governments in Nigeria 1960-1990 with special reference to South Africa

description: Much has been written in recent years on Nigeria's foreign policy behaviour but little attention has been paid to the institutional structures, political processes and problems in the formulation and implementation of these policies. This study addresses itself to these neglected areas in the study of Nigeria's foreign policy. It highlights not only the influence of other countries on foreign policy formulation, but also investigates the influence of international organisations. Most importantly, it points out the continuity of foreign policy within the various Nigerian governments, be they military or civilian governments. The author has also sought to address vital issues, such as how dependent foreign policy formulation is upon the presidential office, and whether this limits the influence of the Ministry of External Affairs. Also investigated is the degree of Nigeria's involvement with the Southern Africa liberation movements and material to do with the actual financial subventions made by Nigeria to them.
