Year: 1999
Subjects: Farm Management

description: Presently farmers being serviced by agricultural co-operatives in Santa Catarina State, Brazil, may receive advice from 3 to 4 technicians each following their speciality - eg. oranges, pigs, dairy, and crops. No concern is given to the farmer’s needs or to his financial and management problems. No one attempts to understand the whole system, with its constraints, threats and opportunities. Farmers have been dissatisfied with the conflicts and problems. This has imposed the recent introduction of whole farm management methods to Brazil has opened an opportunity seen by many to offer a solution to improve the efficiency of their farming systems. Three co-operatives have begun the transition of converting the activities of their technicians from restricted technical assistance to whole farm management system advice. While the technicians, farmers and the principals of the co-operatives are enthusiastic about the approach it is yet too early to precisely measure the success of the transformation. In the paper the current status of the transition and related problems and successes of one cooperative (CooperArco-lris) are described. Methods used to introduce the recommended process, clarification of the objectives and expected immediate and long run outcomes are then discussed with recommendations to others facing the same transition.

description: We present the results of an adaptive optics survey for faint companions among Galactic O-type star systems (V < 8) using the Advanced Electro-Optical System (AEOS) 3.6-meter telescope on Haleakala. We surveyed these O star systems in I-band, typically being able to detect a companion with a magnitude difference of about 6 in the projected separation range of 0.5 to 1.0 arcseconds, and of about 9.5 in the range of 1.0 to 5.0 arcseconds. In the course of the survey, we discovered 40 new companions among 31 of the 116 objects examined and made astrometric and differential magnitude measurements of 24 additional known pairs, several of them being confirmation detections. We present new astrometric orbits for two binaries, BU 1032AB (WDS 05387-0236; sig Ori AB) and SEE 322 (WDS 17158-3344; HD 155889AB). We lack magnitude differences for other filter bands, so it is difficult to determine physical from line-of-sight companions, but we present empirical arguments for the limiting magnitude difference where field contamination is significant.

description: Due to several objective reasons, the sulphur (S) deficiency in agricultural crops in Europe came to the fore in the last decades before the turn of the century. This work gives an overview of the Estonian long-year research concerning winter wheat responses on the S fertilization. This study presents a versatile influence of S application – beginning with the influence on the yield formation, grain yield quantity and quality, followed by the one on the biological quality of wheat proteins, and on the bread-making properties of flour and dough, and ending with the one on the quality indices of baked breads. Field experiments were conducted at two locations on calcaric Cambisol and Podzoluvisol. On the background of N100 or 120 kg ha-1, S was given as granular NS-fertilizers or foliar applied with Sulfur F3000 or with fungicide Thiovit Jet. Flour and dough properties for bread-making were determined by using a farinograph Brabender. The baking tests were carried out in laboratory conditions. The influence of S on the grain yield and quality, and bread-making properties of wheat depended on the year and location. As the average of experiments, the S application significantly increased the grain yield (r = 0.960). The increasing yields were accompanied by decreasing contents of protein and wet gluten. However, due to S application the biological quality of proteins was increasing, because the contents of some essential amino acids were increasing. The significant positive (r = 0.938) effect of the S application on the Gluten index was revealed, which is a good predictor for the baking quality of wheat flour. In addition, some significant positive effects of the S application on the rheological properties of dough and quality indices of baked breads were demonstrated. Thus, the S addition by nitrogen fertilization in parallel with increasing yields improved several bread-making parameters of wheat flour.

description: We investigate the spacetime of anisotropic stars admitting conformal motion. The Einstein field equations are solved using different ansatz of the surface tension. In this investigation, we study two cases in details with the anisotropy as: [1] $p_t = n p_r$ [2] $p_t - p_r = \frac{1}{8 π}(\frac{c_1}{r^2} + c_2)$ where, n, $c_1$ and $c_2$ are arbitrary constants. The solutions yield expressions of the physical quantities like pressure gradients and the mass.

description: The increase in indigenous oil firms’ participation (IOFP) and backward linkages through which additional jobs could be created was the main target of the local content policy (LC policy) implemented in the Nigerian oil sector over the past decade. Thus, the purpose of this paper is to assess whether IOFP and backward linkages mediate the relationship between the LC policy and job creation in the country’s oil sector on which there was little empirical research. Data obtained from Nigerian indigenous oil service firms through self-administered questionnaires were analysed by using a bootstrapping technique. Our results revealed that there was an indirect effect of the LC policy on the creation of new jobs. This finding sheds light on the positive impact of the LC policy. Our results imply that if Nigeria’s LC policy is effective and efficient, increased job opportunities will follow. This may speed up the country’s vision of 2020 on value-addition in achieving economic development through the oil sector.

description: This paper highlights the findings of the research project regarding farmers’ performance based on their management practices. Burger’s scale, which is used to
measure management aptitude, was adapted and used to measure the management performance of farmers. The latter was expressed in terms of thefarmers 'performance index (PI), and it was found that large differences occurred in the PI among farmers (between 27,6 and 99,5). To accommodate all cases, thefarmers were divided into three groups according to PL Statistically significant differences (but not in all cases) were found between farmers with different biographies, as well as between farmers with certain management practices. These differences are related to the implementation of new farming systems.

A text that, like a flow, goes freely from one reference to another and one topic to another, like the words on the calligrams by Buzzati and Arbasino, or the scores by Sylvano Bussotti and Bruno Maderna. The investigation opens and closes several parentheses but focuses specifically on artist book covers, experimentations of musical writing and illustrations by artist-writers like Buzzati and Zavattini while also crossing theatrical sketches, performance and cinema, which push the contamination between narration and image to the extreme. The text ends with the artistic experiments of/on Pier Paolo Pasolini, the result of the happy artistic union of the artist with Fabio Mauri. Pasolini, with Intellectual “undergoes” the projection of his own film Il Vangelo Secondo Matteo, a reflection on the image of the author and his work of art.
In medium T-matrix for nuclear matter with three-body forces - binding energy and single particle properties

description: We present spectral calculations of nuclear matter properties including three-body forces. Within the in-medium T-matrix approach, implemented with the CD-Bonn and Nijmegen potentials plus the three-nucleon Urbana interaction, we compute the energy per particle in symmetric and neutron matter. The three-body forces are included via an effective density dependent two-body force in the in-medium T-matrix equations. After fine tuning the parameters of the three-body force to reproduce the phenomenological saturation point in symmetric nuclear matter, we calculate the incompressibility and the energy per particle in neutron matter. We find a soft equation of state in symmetric nuclear matter but a relatively large value of the symmetry energy. We study the the influence of the three-body forces on the single-particle properties. For symmetric matter the spectral function is broadened at all momenta and all densities, while an opposite effect is found for the case of neutrons only. Noticeable modification of the spectral functions are realized only for densities above the saturation density. The modifications of the self-energy and the effective mass are not very large and appear to be strongly suppressed above the Fermi momentum.

Kieffer (1907b) only described the female of this species. The female specimen at the MNHN appears to have been collected at the university in Bitche where Kieffer used to teach, and subsequently donated to the MNHN (Kelner-Pillault 1958). The specimen (MNHN EY22476) is point mounted and in good condition.
 Dessart left a label on the specimen in 1966 indicating that it is actually Ceraphron pedes Förster, 1861 but never officially synonymized it according to Johnson & Musetti (2004). There is a second female specimen at the Natural History Museum in London (NHMUK010812034) that Dessart viewed in 1965 and also identified as Ceraphron pedes Förster, 1861. It is unclear why Dessart never published this. Both the NHMUK and MNHN specimens were collected by P. Cameron and have determination labels from Kieffer, and are presumably syntypes. Dessart labeled the type at the NHMUK as a syntype, but the type at the MNHN still bears a holotype label.

description: Contact and related phenomena, such as friction, wear or elastohydrodynamic lubrication, remain as one of the most challenging problem classes in nonlinear solid and structural mechanics. In the context of their computational treatment with finite element methods (FEM) or isogeometric analysis (IGA), the inherent non-smoothness of contact conditions, the design of robust discretization approaches as well as the implementation of efficient solution schemes seem to provide a never ending source of hard nuts to crack. This is particularly true for the case of beam-to-solid interaction with its mixed-dimensional 1D-3D contact models. Therefore, this contribution gives an overview of current steps being taken, starting from state-of-the-art beam-to-beam (1D) and solid-to-solid (3D) contact algorithms, towards a truly general 1D-3D beam-to-solid contact formulation.

description: This paper outlines the new human resource requirements in agricultural sector as well as transitional changes and adjustments in agricultural higher education and farm management training in Hungary facing EU accession. During ongoing transition the ownership, production and organisation structure of Hungarian agriculture has been fundamentally changed. Most of large-scale (state owned or co-operative ) farms has been privatised and decentralised and parallely private commercial farming expanded. Accordingly, under an increasing market orientation the requirements against the knowledge, skills, tools and attitudes of farm managers are also altering and extending. In the new farm business environment there is less demand for agricultural engineers with theoretical and specialised knowledge. Considering the new professional profile graduate students should be fully aware of basic economic and marketing principles of farming and preparedfor performing several practical tasks in the daily operation of a farm business. Besides strengthening the curriculum with new management oriented subjects it is necessary to introduce new training methods such as demonstration of case studies and pilot models, as well as training of problem oriented thinking, system approach, ability of working in teams and using different management tools as the advanced information and communication technology (1CT). By presenting the example of Kaposvar Faculty of Pannon Agricultural University this paper demonstrates how a regional agricultural educational and extension center in south-west of Hungary has responded to the challenge of transition and found reasonable ways and solutions for improving training ofpotential farm managers.

description: The paper reports on the outcomes of a Canadian study to examine risk management issues of government impacts on agriculture. The study considered public policy impacts related to agriculture, and provided an initial analysis of the risks created through multi layers of legislative and regulatory decisions. Evaluation work was at four levels of government; international, federal, provincial, municipal, as well as at the community level. Research showed an absence of analysis, documentation, studies and findings about how government decisions influence farming, and the associated costs inside the farm gate. The initial analysis has involved detailed studies in four Canadian provinces, and survey work in the other provinces and territories, and showed farmers are working with an increasing number of government acts, regulations, and administrative rules from both domestic and international governments, and trade and commodity stakeholders. The results are conflicting, overlapping, and duplicated public policy. The analysis showed there are added costs of food production in a society that expects food to be safe, of high quality, readily available, and inexpensive. Additional costs due to legislation are largely absorbed by the producers with limited opportunity to pass on those costs to the consumer. The report provided SI recommendations supported by four implementation plans. Phase Two of the project, to examine the remaining provinces and territories, and provide the first comprehensive national study, is the next step.

description: Results from initial helioseismic observations by Solar Optical Telescope onboard Hinode are reported. It has been demonstrated that intensity oscillation data from Broadband Filter Imager can be used for various helioseismic analyses. The k-omega power spectra, as well as corresponding time-distance cross-correlation function that promises high-resolution time-distance analysis below 6-Mm travelling distance, were obtained for G-band and CaII-H data. Subsurface supergranular patterns have been observed from our first time-distance analysis. The results show that the solar oscillation spectrum is extended to much higher frequencies and wavenumbers, and the time-distance diagram is extended to much shorter travel distances and times than they were observed before, thus revealing great potential for high-resolution helioseismic observations from Hinode.

description: Earlier researchers studied and described the anomalous presence of Paleozoic fossils transplanted on the Quaternary upper Mid-Atlantic Coastal Plain (MACP) without scrupulous analysis of the fragmentary evidence on barrier islands and headlands bordering the Atlantic Ocean. The recent discovery of a trove of Paleozoic fossiliferous pebbles on the beaches of Long Beach Island, New Jersey (LBI) has reinvigorated interest in this shoreline region, an investigation of which is the focus of the present report. Surveys of three linearly extensive New Jersey beaches suggest that only replenished beaches, such as LBI, potentially harbor fossils. The natural, undisturbed beaches of Island Beach State Park and Brigantine Wildlife Refuge exhibit only complete modern mollusks on the foreshore and molluscan shards on the backshore without gravel and are devoid of fossils. Prospecting both types of Atlantic Ocean beaches suggests that replenished beaches initially carry Paleozoic fossils and gravel but eventually revert to a more natural state so that only recently replenished beaches may be expected to reveal significant fossils and gravel on the surface.  Scrutiny of fossils found on replenished beaches of LBI reveals two distinct types of fossiliferous pebbles; Irregular shaped, rough surface with pristine fossils regarded as glaciogenic and a second smaller type of rounded, smooth surface with abraded fossils regarded as fluviogenic. It is notable that fossiliferous pebbles and gravel are well sorted and range from 5 – 20 millimeters in maximum dimension mixed with gravel of the same size. Maximum size is limited by screens in the dredge outflow equipment. Offshore stratigraphy suggests that the irregular pebbles are embedded in the Pleistocene-Recent veneer, and the rounded type from the underlying fluvial Miocene-Pliocene deposits. This unequal distribution suggests that dredging for beach replenishment on LBI taps the Pleistocene veneer deposits but occasionally penetrates to the underlying more gravelly fluvial Miocene-Pliocene. Examples of these two types are provided with the complete inventory of specimen posted in the Data Repository.

description: We study the quantum dynamics of an ion confined in a radiofrequency trap in interaction with either a Bose or spin-polarized Fermi gas. To this end, we derive quantum optical master equations in the limit of weak coupling and the Lamb-Dicke approximations. For the bosonic bath, we also include the so-called "Lamb-shift" correction to the ion trap due to the coupling to the quantum gas as well as the extended Fröhlich interaction within the Bogolyubov approximation that have been not considered in previous studies. We calculate the ion kinetic energy for various atom-ion scattering lengths as well as gas temperatures by considering the intrinsic micromotion and we analyse the damping of the ion motion in the gas as a function of the gas temperature. We find that the ion's dynamics depends on the quantum statistics of the gas and that a fermionic bath enables to attain lower ionic energies.

description: Quantile (and, more generally, KL) regret bounds, such as those achieved by NormalHedge (Chaudhuri, Freund, and Hsu 2009) and its variants, relax the goal of competing against the best individual expert to only competing against a majority of experts on adversarial data. More recently, the semi-adversarial paradigm (Bilodeau, Negrea, and Roy 2020) provides an alternative relaxation of adversarial online learning by considering data that may be neither fully adversarial nor stochastic (i.i.d.). We achieve the minimax optimal regret in both paradigms using FTRL with separate, novel, root-logarithmic regularizers, both of which can be interpreted as yielding variants of NormalHedge. We extend existing KL regret upper bounds, which hold uniformly over target distributions, to possibly uncountable expert classes with arbitrary priors; provide the first full-information lower bounds for quantile regret on finite expert classes (which are tight); and provide an adaptively minimax optimal algorithm for the semi-adversarial paradigm that adapts to the true, unknown constraint faster, leading to uniformly improved regret bounds over existing methods.

The Application of Precision Farming Technologies in Australia

description: The adoption of Precision Farming technologies (DGPS, CIS, Yield maps, and Variable Rating)is increasing in Australia. A number of farmers and technology suppliers were interviewed to ascertain the returns achieved or expected by adopting some of the new technology. The purchase ofsophisticated dGPS receivers could be justified by larger cropping enterprises (>2000 hectares) particularly in regard to spraying and sowing and the adoption of controlled traffic. Yield maps while identifying variation over a field are of limited use until spatial analysis and agronomic knowledge catch up with the technology. Variable Rate technology at level 2 has a number of feasible applications when used in conjunction with multisite soil tests within a field. The use of handheld dGPS systems were claimed by a number of farmers to increase efficiency and to help make more informed decisions.

description: We extend the key idea behind the generalized Petviashvili method of Ref. \cite{gP} by proposing a novel technique based on a similar idea. This technique systematically eliminates from the iteratively obtained solution a mode that is "responsible" either for the divergence or the slow convergence of the iterations. We demonstrate, theoretically and with examples, that this mode elimination technique can be used both to obtain some nonfundamental solitary waves and to considerably accelerate convergence of various iteration methods. As a collateral result, we compare the linearized iteration operators for the generalized Petviashvili method and the well-known imaginary-time evolution method and explain how their different structures account for the differences in the convergence rates of these two methods.

description: From the spare journals of John Winthrop and William Bradford to the Day of Doom exhortation of Michael Wigglesworth, one can see the basis for a commonly held image of the early Puritan colonists as being a stern, humorless community. This is not inconsistent with the theological underpinnings of the Puritans' faith. Further, some research, such as that by John Demos and Karin Calvert, has concluded that the children of these colonists were not accorded the status of individuals; rather they were variously held at an emotional distance or otherwise marginalized, in part because of the very real threat of their deaths. I believe this is too narrow a view, one that is not supported by a deeper examination of the texts of early American writers. It is my contention that the diaries, sermons, poetry and other narratives of writers from 1620 to 1800 belie the stereotype of reserved, unemotional Puritans and colonists.

Through an examination of these texts, with specific attention to the representations of the death of children, this paper will reveal a rich supply of examples of the joy and anguish parents' felt for their children and the deep grief and emotion evident as they coped with the death of their children. Rather than reflecting an emotionally detached parent-child relationship, these texts reveal the opposite. The texts do reveal a tension, however. These people were looking for good grief, for a way to accommodate the deaths of their children and to express their grief within the teachings of their faith and within the bounds of social mores. This struggle is evident in their diaries, sermons and other writings, and while the specific Puritan theology evolves into a more ecumenical representation, the essential truth that children are the hope and future of families and society is consistently represented in these writings.

description: Particle size and shape are key factors influencing the properties of particulate and agglomerated materials, and having an impact on a quality as well as utilization of a final product. In case of plant biomass particle morphology is greatly irregular. Large errors at most determinations of biomass particle sizes are caused by simplification on a single parameter of size, assuming particle sphericity or circularity. Thus, the aim of a present research was to determine the particle size in a complex way. Pine sawdust as an experimental material and typical biofuel feedstock was ground by a hammer mill to a fraction size of 12 mm. The dimensional features of such ground sawdust particles were identified for all particles individually via photo-optical analysis, a method based on a digital image processing that is sensitive to irregular particles’ shapes. The particles were described mainly by variables of length, max width, equivalent diameter, max and min feret diameter, sphericity, roundness, circularity together with length/width ratio and aspect ratio. Data were analysed by descriptive statistics, i.e. by arithmetic means, medians, minimum and maximum values, variance and standard deviation. The obtained results may contribute to a better knowledge of material properties needed for designing an optimal technology for the production of quality biofuels.

description: By European Cooperative Programme for Plant Genetic Resources (ECPGR), oregano (Origanum vulgare L.) is included on the list of priority species of medicinal and aromatic plants. In Latvia, it is important to cultivate oregano for keeping biodiversity and for meeting the needs of medicinal plant`s production. 44 accessions of oregano from the ex situ collection of genetic resources of medicinal and aromatic plants, attached to the Latvia University of Life Sciences and Technologies, were analysed during 2012–2014. Plants` morphological characteristics were described by the Draft Descriptor List of oregano, using the methodology of ECPGR. The essential oil was isolated using solvent-free microwave extraction method and analysed by gas chromatograph Hewlett Packard 6890 equipped with flame ionization detector FID and polar capillary column HP 20M. The results showed, that oregano accessions differ morphologically. Accessions are characterized with dense branching and the possibility to create big biomass. Local oregano is poor in content of essential oil, but 17 compounds were identified as the principal. As well as the correlation between the content of essential oil and colour of flowers in full flowering stage was observed – it is higher for accessions with dark flowers. Also, the influence of meteorological conditions per vegetation period (year) on chemical characteristics was significant (p < 0.05).

description: The two most successful methods for exoplanet detection rely on the detection of planetary signals in photometric and radial velocity time-series. This depends on numerical techniques that exploit the synergy between data and theory to estimate planetary, orbital, and/or stellar parameters. In this work, we present a new version of the exoplanet modelling code pyaneti. This new release has a special emphasis on the modelling of stellar signals in radial velocity time-series. The code has a built-in multidimensional Gaussian process approach to modelling radial velocity and activity indicator time-series with different underlying covariance functions. This new version of the code also allows multi-band and single transit modelling; it runs on Python 3, and features overall improvements in performance. We describe the new implementation and provide tests to validate the new routines that have direct application to validate the new routines that have direct application to exoplanet detection and characterisation. We have made the code public and freely available at https://github.com/oscaribv/pyaneti. We also present the codes citlalicue and citlalatonac that allow one to create synthetic photometric and spectroscopic time-series, respectively, with planetary and stellar-like signals.

description: We study a simple one-dimensional quantum system on a circle with n scale free point interactions. The spectrum of this system is discrete and expressible as a solution of an explicit secular equation. However, its statistical properties are nontrivial. The level spacing distribution between its neighboring odd and even levels displays a surprising agreement with the prediction obtained for the Gaussian Orthogonal Ensemble of random matrices.

description: Motivated by applications to black hole physics and duality, we study the effect of higher derivative corrections on the dimensional reduction of four-dimensional Einstein, Einstein Liouville and Einstein-Maxwell gravity to one direction, as appropriate for stationary, spherically symmetric solutions. We construct a field redefinition scheme such that the one-dimensional Lagrangian is corrected only by powers of first derivatives of the fields, eliminating spurious modes and providing a suitable starting point for quantization. We show that the Ehlers symmetry, broken by the leading $R^2$ corrections in Einstein-Liouville gravity, can be restored by including contributions of Taub-NUT instantons. Finally, we give a preliminary discussion of the duality between higher-derivative F-term corrections on the vector and hypermultiplet branches in N=2 supergravity in four dimensions.

description: The rovibronic (rotation-vibration-electronic) spectrum of the calcium monohydroxide radical (CaOH) is of interest to studies of exoplanet atmospheres and ultracold molecules. Here, we theoretically investigate the $\tilde{A}\,^2Π$--$\tilde{X}\,^2Σ^+$ band system of CaOH using high-level \textit{ab initio} theory and variational nuclear motion calculations. New potential energy surfaces (PESs) are constructed for the $\tilde{X}\,^2Σ^+$ and $\tilde{A}\,^2Π$ electronic states along with $\tilde{A}$--$\tilde{X}$ transition dipole moment surfaces (DMSs). For the ground $\tilde{X}\,^2Σ^+$ state, a published high-level \textit{ab initio} PES is empirically refined to all available experimental rovibrational energy levels up to $J=15.5$, reproducing the observed term values with a root-mean-square (rms) error of 0.06~cm$^{-1}$. Large-scale multireference configuration interaction (MRCI) calculations using quintuple-zeta quality basis sets are employed to generate the $\tilde{A}\,^2Π$ state PESs and $\tilde{A}$--$\tilde{X}$ DMSs. Variational calculations consider both Renner-Teller and spin-orbit coupling effects, which are essential for a correct description of the spectrum of CaOH. Computed rovibronic energy levels of the $\tilde{A}\,^2Π$ state, line list calculations up to $J=125.5$, and an analysis of Renner-Teller splittings in the $ν_2$ bending mode of CaOH are discussed.
