description: The summer of 2006 was devoted to conducting an in-depth, follow-up survey of all Farm Service Agency (FSA) Borrower Training Workshop participants. FSA Borrower Training Workshops began in February 1995 and have involved 1,004 farms and 1,500 individuals. This paper will share survey results concerning long-term workshop effectiveness. Survey results indicate participants got meaningful, useful, and profitable education from the workshops. Further, the paper will relate the effectiveness of different farm management education teaching concepts and tools used during the workshops. Evaluations conducted at the end of each workshop suggest our efforts have been successful. Participants rated the materials, instructors, and the whole educational experience as being worthwhile. Ninety-seven percent indicated they would recommend the training to other farmers. The follow-up survey was conducted to determine if the farm financial management training had lasting value to participants.

subject: timeliness

description: All farm firms, big or small, must manage four different and often intertwined conflicting parts. These are production, marketing, human relations and finance. Itâ€™s probably fair to say that in most farms, production is the fun part and finance is the stuff thatâ€™s left to bookkeepers. This is unfortunate because the financial part of the farm plays a larger role in firm success than ever before. This is largely due to the increasing importance of timeliness in the decision making stemming from the farmâ€™s financial performance in an increasingly competitive environment, both domestically and overseas. It is also sad, but typical, that the essential financial numbers tend to arrive back from accountants long after the owners should have acted on them. The main reason on many farms is that accountants tend to concentrate on taxes, while owners should focus on financial management decisions, which usually require different numbers. This paper attempts to clarify the mystery of, and ignorance about, all those essential financial statements, by selecting six simple financial management numbers that are timely, that owners can follow easily and therefore improve both their farm decision making and their competitive advantage. The numbers are subjectively ranked in the authorsâ€™ views of their importance. These ranked numbers are 1. the firmâ€™s cash and its availability. Cash pays the bills and is the fuel that drives the farmâ€™s finances. 2. net income and how it is used. Net income, or profit, pays for new farm investment, retires principal and provides salaries to the farmâ€™s owners. 3. earnings before interest and taxes, otherwise known as EBIT. This indicates whether the farmer should reduce debt now and therefore lower future interest payments, or invest in a depreciable asset to reduce taxes, or simply accept the number. 4. leverage, which helps in debt management, and shows how much debt the farm owes for every $1 that it owns. 5. the farmâ€™s main cash costs. There are rarely more than five major expenditures on any farm, and these account for at least 75% of the farmâ€™s cash costs, and therefore perhaps 60% of the farmâ€™s total costs. 6. sales, rather than total revenue. Sales provide cash and total revenue may, and often, does not. The paper emphasizes the simplicity of firstly finding these numbers and secondly, using them as trends for decisions. It illustrates the types of decisions in each of the six categories and shows their importance in subsequent firm management.

Tolerance in Western hemlock
Creators: name: Keller, Rodney Alan
Publisher: name: University of British Columbia
Year: 2011

description: Needle anatomy, water response and gas exchange characteristics of juvenile ecophenes or habitat forms of Western hemlock (Tsuga hetero-phylla) from sites of varying degrees of exposure were compared and contrasted. This was done to gain information about the seemingly broad adaptative spectra displayed by ecophenes of this species within its natural habitat. Some differences were found in needle anatomy and chlorophyll content; the ratio of needle area to needle dry weight increased with the amount of shelter and chlorophyll content was less in the exposed ecophene. A scanning electron microscope was used to observe needle surfaces and cross sections were examined through a light microscope. The exposed ecophene had a thicker cuticle, thicker cell walls, more surface wax and a more circular cross section than sheltered ecophene. A series of experiments, both in the field and in the laboratory was run to test the postulate that response to changes in environmental water demand was different between the ecophenes. Results supported the postulate and suggested that the sheltered ecophene was unable to control transpirational loss under high evaporative demand. A relationship was established between carbon uptake and relative turgidity. Laboratory experiments were run with juvenile whole trees to test the postulates that diffusion resistances, carbon uptake, light compensation, and carbon uptake under different degrees of evaporative demand were different for the two ecophenes. Carbon uptake by the sheltered ecophene did not reach light saturation as rapidly as uptake by the exposed ecophene. Increase of carbon uptake by the sheltered ecophene vas probably limited by diffusional processes. Increase in uptake by the exposed ecophene at high light was limited by non-diffusional processes. Although the shade ecophene displayed a higher carbon uptake and light saturation intensity than the sun ecophene on a unit area basis, the two ecophenes were statistically inseparable when uptake was expressed as a percentage of maximum uptake per tree. Lowered relative humidity lowered carbon uptake and raised transpiration rates of both sun and shade ecophenes.
AP - Assisting Property Owners With Wealth Transfers: Anecdotal Experiences From The United States And New Zealand

Subjects: subject: Public Economics
subject: wealth/business transfer

description: Anecdotal experiences are discussed relative to efforts assisting property owners with wealth transfers. The author draws from his work in the United States and while on sabbatical in New Zealand. Initially focus was given to the technical aspects and details of asset transfer: organizational structures, ownership of assets, percentages of annual transfer through gifts, etc. Experience led to a redirection of emphasis in dealing with property owners. Efforts were redirected to hard issues of economics (can the farm afford succession) and to soft issues of management, such as mission and vision statements, articulation of values by the property owners ultimately leading to establishment of goals and plans. The transition of wealth, consistent with owner plans, is then executed incorporating business plans, gifting, sales, and bequests all sensitive to tax constraints if any. The most difficult issue often times, is the gathering around the kitchen table to begin the discussion.

description: We present a new Python pipeline for processing data from astronomical long-slit spectroscopy observations recorded with CCD detectors. The pipeline is designed to aim for simplicity, manual execution, transparency and robustness. The goal for the pipeline is to provide a manual and simple counterpart to the well-established semi-automated and automated pipelines. The intended use-cases are teaching and cases where automated pipelines fail.
 From raw data, the pipeline can produce the following output:
 * A calibrated 2D spectrum in counts and wavelength for every detector pixel.
 * A 1D spectrum extracted from the 2D spectrum in counts per wavelength (for point-like objects).
 * A flux-calibrated 1D spectrum (for point-like objects).
 The products are obtained by performing standard procedures for detector calibrations (Howell, 2006; Richard Berry, 2005), cosmic-ray subtraction (McCully et al., 2018; van Dokkum, 2001), and 1D spectrum extraction (Bradley et al., 2024; Horne, 1986).

description: Too often farm advisors, either in the private or public sectors, follow the adage: â€œDo as I say, not, as I doâ€. Farm advisors frequently become â€œmembersâ€ of a clientâ€™s family, and in doing so, may jeopardize what is near and dear, their own family. As with the cobbler, whose children having no shoes to wear, the farm advisor needs to focus on management issues of the home economy. For successful farm advisors, time is a precious commodity indeed; a working vacation with a spouse/partner can be a solution to accomplish buy-in for new business ideas and continued success in established enterprises. This paper discusses a frame work for a working holiday centred on a questionnaire to which they respond to one another either in oral or written means. The end product of such a working holiday is that spouses/partners have re-established mutual goals and reasons for pressing on.

description: Research shows that worker output is not a constant and that labour productivity is internationally an important component of agricultural production. Labour productivity plays a prominent role in creating the competitiveness of a specific farming business and even the whole economy. This situation became a concern for farmers as the pressure to increase minimum wages escalated in recent times. In 2006, the South African Government announced a total increase in wages of 34, 59% over a three year period (2006â€“2008). It is basically impossible to increase productivity of labour to the same extent over this period. This paper examines labour productivity, the influence of increasing labour costs on profitability and sustainability, as well as how farmers must take this issue into account when production planning is done.

description: MINDtheGEPs takes a multidisciplinary multidimensional approach to challenging gender imbalances across five different countries: Italy, Spain, Serbia, Ireland, Poland. The project is implementing Gender Equality Plans (in this document also referred to as GEPs) across various types of research performing organisations, four of them public universities, one public non-academic research institute, one academic, and one private technological institute. The work to communicate and disseminate results from the project is led by Uppsala University (UPP) and Elsevier together. This report builds on strategy outlined in D8.1 – Visual identity and guidelines for use, D8.2 – Dissemination and communication plan, D8.6 – Dissemination and exploitation plan update, and D8.3 – Exploitation plan.

To ensure the strategy and plan are flexible and suit the needs of the project and its partners, MINDtheGEPs is using a three-step approach to Dissemination, Communication & Exploitation (DCE) strategy and plan. Due to the extension of the project by six months, the timelines described in the initial strategy and plan (D8.2) have been adjusted to accommodate the delivery of reports.

In the initial phase (M1-18), efforts were focused on identifying and connecting with stakeholders and gatekeepers to create awareness of the project and what it can be expected to produce. This work is described in D8.1 & D8.2.

In the second phase (M19-30), which concludes with this report, we developed a project exploitation strategy, described in D8.3 and outlined in section 3 of this report. This strategy outlines key routes for the exploitation of the project’s results. Direct activities to exploit results include the development of GEPs, provision of guidelines, datasets and knowledge, as well as indirect results achieved through the implementation in partner organisations (e.g., increased gender balance, increased number of publications authored by women, increased number of publications using gender and sex variables). D8.3 identifies a number of key routes for exploitation.

This report describes our strategy and plan for the final phase (M31-54). During this phase, the consortium will work to implement the key routes for exploitation, and ensure that the results are widely communicated to stakeholders and other audiences, thereby increasing the impact of project outputs. This iteration of the DCE plan also includes an evaluation of key performance indicators (benchmarking metrics), along with a publication strategy and plan.

description: The Agulhas Plain lies at the southern-most tip of Africa and falls within the Cape Floral Kingdom. It covers an area of approximately 2 160 km2 of coastal lowlands and low hills. This exceptionally species-rich area has been severely fragmented by alien plant infestation, agriculture and urban development. In order to guide conservation efforts whilst addressing the socio-economic needs in the area, a process of rural area-wide planning has commenced in the region. This is carried out by the Landcare division of the Department of Agriculture in partnership with conservation authorities, farmers, local government and communities. Agritourism is identified as a high- potential industry in this region. In order to guide decision-making, an intensive data-collection exercise has commenced, whereby land use on the Plain is being mapped at 1:10 000 scale and relevant information is collated in a Geographic Information System (GIS). This paper will examine the role which GIS, spatial data and associated technologies play in the project â€“ and specifically how the information generated is made relevant and accessible to regional planners and indeed all role players.

description: We use a set of high-resolution hydrodynamical simulations of clusters of galaxies to study the build-up of the intracluster light (ICL), an interesting and likely significant component of their total stellar mass. Our sample of groups and clusters includes AGN feedback and is of high enough resolution to accurately resolve galaxy populations down to the smallest galaxies that are expected to significantly contribute to the stellar mass budget. We describe and test four different methods to identify the ICL in simulations, thereby allowing us to assess the reliability of the measurements. For all of the methods, we consistently find a very significant ICL stellar fraction (~45%) which exceeds the values typically inferred from observations. However, we show that this result is robust with respect to numerical resolution and integration accuracy, remarkably insensitive to changes in the star formation model, and almost independent of halo mass. It is also almost invariant when black hole growth is included, even though AGN feedback successfully prevents excessive overcooling in clusters and leads to a drastically improved agreement of the simulated cluster galaxy population with observations. In particular, the luminosities of central galaxies and the ages of their stellar populations are much more realistic when including AGN. In the light of these findings, it appears challenging to construct a simulation model that simultaneously matches the cluster galaxy population and at the same time produces a low ICL component. We find that intracluster stars are preferentially stripped in a cluster's densest region from massive galaxies that fall into the cluster at z>1. Surprisingly, some of the intracluster stars also form in the intracluster medium inside cold gas clouds that are stripped out of infalling galaxies.

description: Sub-Saharan Africans are often frustrated by bad news emanating from their continent, including mismanagement stories and prognoses of agricultural failure. While acknowledging the huge challenges facing Africa, this Paper (widely illustrated from several African countries) seeks to identify key factors involved in a range of agricultural management practices and contextual realities which are actually successful and offer further potential. Innovative and sustainable management practices are pursued in Africa with vigour in many places, affecting soils, crops and animals through mixed cropping, conservation farming, groupwork, multiprofessionality, part-time farming, use of mobile telephones in farm produce marketing and various strategies for food security through strengthening local Food Chains.

AP - Farming Carbon In Australia

Publisher: name: Unknown
Year: 2007
Subjects: subject: Resource /Energy Economics and Policy
subject: carbon
subject: energy conservation

description: The clearing of farming land over the last four hundred years has released large quantities of carbon dioxide into the atmosphere. This clearing and the subsequent decline in organic matter is estimated to have contributed almost twice the carbon released from fossil fuel use since 1850. The big opportunity is to reverse the decline of soil organic matter - storing carbon and the same time improving soil productivity. This potential to store carbon in Australia is lower than in temperate areas, such as the USA, where ten long-term studies of no-tillage show an increase of 0.6 t.carbon/ha/yr. A good outcome in Australia is a gain of 0.1-0.15 t. C/ha per year. While useful and much better than releasing carbon, this is not enough for farmers to receive a significant â€˜carbon creditâ€™ payment. Storing carbon is a win-win situation however â€“ with improved organic matter resulting in better soil health and contributing to better crop yields. Saving energy on farms is also more profitable while reducing greenhouse emissions. A â€œFarming Carbonâ€ program is being conducted by the author with 50 farmers in Queensland, helping them to monitor soil organic matter and discuss farming practices which can sequester carbon and save energy.

description: We address light propagation in couplers with longitudinal biharmonic modulation of refractive index in neighboring channels. While simplest single-frequency out-of-phase modulation allows suppression of coupling for strictly defined set of resonant frequencies, the addition of modulation on multiple frequency dramatically modifies the structure of resonances. Thus, additional modulation on double frequency may suppress primary resonance, while modulation on triple frequency causes fusion of primary and secondary resonances.

description: The 2003 reform of Common agricultural policy to be implemented in Slovenia in 2007 could have significant impact on the economic position of some agricultural sectors in Slovenia. Out of economics sight one can expect a drastic impact especially in sectors like beef, where percentage of pre-reform production coupled direct payments was very high - up to 70 % of gross margin achieved. This leads farmers to seek new production plans. For this purpose detailed specified static linear programming model has been developed and applied to the hypothetical agricultural holdings in order to find optimal production plans by maximizing total gross margins. Model results confirm that the reform should have unfavourable impacts on farms with intensive production practice, especially those with high livestock density. Obtained results indicate that the negative impacts can be mitigated by combining different production activities and technologies under given constraints on resources available. Model results also confirm the growing importance of CAP rural development payments, among them particularly inclusion into agri-environmental measures.

description: Configurations of vortex-strings stretched between or ending on domain walls were previously found to be 1/4 Bogomol'nyi-Prasad-Sommerfield(BPS) states in N=2 supersymmetric gauge theories in 3+1 dimensions. Among zero modes of string positions, the center of mass of strings in each region between two adjacent domain walls is shown to be non-normalizable whereas the rests are normalizable. We study dynamics of vortex-strings stretched between separated domain walls by using two methods, the moduli space (geodesic) approximation of full 1/4 BPS states and the charged particle approximation for string endpoints in the wall effective action. In the first method we explicitly obtain the effective Lagrangian, in terms of hypergeometric functions, and find the 90 degree scattering for head-on collision. In the second method the domain wall effective action is assumed to be U(1)^N gauge theory, and we find a good agreement between two methods for well separated strings.

description: We present an extended discussion of a recently proposed theoretical approach for off-resonance tunneling transport. The proofs and the arguments are explained at length and simple analogies and illustrations are used where possible. The result is an analytic formula for the asymptotic tunneling conductance which involves the overlap of three well defined physical quantities. We argue that the formula can be used to gain fresh insight into the tunneling transport characteristics of various systems. The formalism is applied here to molecular devices consisting of planar phenyl chains connected to gold electrodes via amine linkers.

description: The main objective of this paper is to demonstrate how data envelopment analysis (DEA) and production function analysis are combined to evaluate the input usage decisions of technically inefficient maize producers and to estimate potential yield gains from reallocating inputs. The data for this research originates from a production cost survey. Two distinct quadratic production functions were estimated for DEA-determined technically efficient and inefficient farmers using a dummy variable approach. Results indicate that the yield gains are large if farmers are able to produce in a technically efficient manner while maintaining current input levels. Results further indicate that even though a producer may be technically inefficient, yield gains and therefore increased profits are possible if such farmers adjust nitrogen application rates. The conclusion is that failure to recognise the fact that DEA-determined technically efficient and inefficient producersâ€™ production processes are characterised by two distinct production functions renders uniform input recommendations inappropriate. In future, extension officers should aim to develop input recommendations taking these inefficiencies into account.

The observed numbers of events are in general agreement with the Standard Model predictions. Seven di- and tri-lepton events are observed in e^+p collision data with a scalar sum of the lepton transverse momenta above 100 GeV while 1.94+-0.17 events are expected. Such events are not observed in e^-p collisions for which 1.19+-0.12 are predicted. Total visible and differential di-electron and di-muon photoproduction cross sections are extracted in a restricted phase space dominated by photon-photon collisions.

description: A review of 183 papers published between 1990 and 2006 lead to development of a typology of farm management decision making (FMDM) research. An existing model which categorises decision research according to purpose as being either D:descriptive, N: normative or P: predictive was blended with a second form of categorisation based on six emergent decision domains: (1) factors, (2) processes, (3) events, (4) evaluation, (5) patterns and (6) aids. The result was a typology of seven main discernible types of FMDM research. Each of these types is outlined and examples of representative publications listed. Finally, some trends in publication patterns, in accord with this typology, are presented. This work is presented in the hope it helps readers to navigate more easily though a large and complex literature.

The effect of instruction in modular arithmetic on the ability of grade 6 students to divide fractions and give a rational explanation of the process
Creators: name: MacDonald, Alexander David
Publisher: name: University of British Columbia
Year: 2011

description: The problem under investigation in this study was to find out what relationship a unit in modular arithmetic might have to Grade 6 pupils' skill in computing the division of fractions and to their understanding of the mathematical basis of the algorithm. It was hypothesized that a unit in modular arithmetic would aid in developing skill in computing and understanding of the algorithm. The study was conducted with a sample of 58 Grade 6 students from the same school. The subjects were assigned to two treatment groups. Both groups received a review of fraction concepts at the beginning of the study. Following this, one group was taught modular arithmetic while the other group reviewed adding and subtracting of fractions. Then both groups were taught multiplication and division of fractions. Following the instruction period, both groups were tested for ability to compute division of fractions. To test understanding of the division of fractions algorithm, an interview inventory test was administered to all subjects in both groups. A statistical analysis of the data from these tests revealed no support for the hypotheses. The conclusion was that teaching modular arithmetic to the Grade 6 pupils participating in the study did not appear to improve their ability to compute division of fractions nor their understanding of the mathematical basis of the division of fractions.

description: A perplexing conundrum exists within the Australian agribusiness sector: there are strong career opportunities and a healthy number of job vacancies but fewer students entering higher education (HE) to study in this area. A lack of responsiveness, inflexibility and the undesirability of current HE courses have been suggested as one reason for this enigma. It is time for some reflection on how HE can meet the needs of the agribusiness industry in producing job-ready graduates. This study reflects on the issues at hand having canvassed the views of other major stakeholders, including employers, students, careers advisers and academics. It identifies the role of the agribusiness industry to the Australian economy and its growing need for highly trained and educated professionals. The criticisms of HE that are preventing students from enrolling in agricultural related courses are explored and recommendations for improving student participation are made.

description: 'Albert Lortzing - Der Wildschiitz, (The Creative Process)', is a critical analysis of both the libretto and score of Lortzing's comic opera, Der Wildschiitz. The dissertation falls into two sections: Part 1 is a consideration of the original source and the development of the libretto; Part 2, a consideration of the musical setting of this libretto. Lortzing's criteria for selection of material are identified, then the background to and content of the original play considered in detail before proceeding to a comparison between the play and the libretto. Biographical information and commentary is introduced which lays particular emphasis on Lortzing's background as author in order to comment on those factors which may have influenced his choice of subject matter and to suggest possible reasons for identified similarities and differences between the play and the libretto. The consideration of the musical setting of the libretto is introduced by Lortzing's background as a musician and an assessment of the forces available to him when he prepared the score before proceeding to an analysis of the complete score. Although reference is made to the possible influence of other composers on Lortzing's style, there is no direct attempt to evaluate Lortzing's music by comparison with works of his contemporaries. The prime objective of the dissertation, to identify the process by which Lortzing transformed Kotzebue's comedy, Der Rehbock, into the comic opera, Der Wildschiitz, gives a clear insight into Lortzing's capabilities as librettist and composer and some insights into the state of opera production in Germany from c.1825 - 1843.

description: Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for the determination of the current mass of atmospheric methane and the most up-to-date determination of D/H from Cassini/CIRS infrared spectra allow us to show that photochemical enrichment of deuterium is not sufficient to be the sole mechanism yielding the measured D/H value. A possible fractionation between CH3D and CH4 during the escape process may slightly enhance the deuterium enrichment, but is not sufficient to explain the observed D/H value over the range of escape values proposed in the literature. Hence, alternative mechanisms such as a primordial deuterium enrichment must be combined with the photochemical enrichment in Titan's atmosphere in order to explain its current D/H value.

Subjects: Risk and Uncertainty

description: Extension education in the rural United States is changing as the demographics shifts by agricultural operators are better understood. RightRisk is one program offered across the United States attempting to address the evolving needs for risk management by todayâ€™s agricultural managers. Program offerings began with development of a risk simulation â€“ Ag Survivor â€“ but now include a ten-step process for strategic risk management with accompanying tools for implementation. Additional courses covering other dimensions of risk management have been developed, including: Insuring Success, Feasibility of Alternative Rural Enterprises, Taxes for Agricultural Enterprises, AGR-Lite, and a two-module course entitled A Lasting Legacy. Embracing new technologies through the use of personal response systems and web-based delivery continue to make RightRisk programming engaging for managers of rural farms and ranches. This flexibility and broad relevance of the fundamental concepts presented make these educational programs appealing for application in many areas, including outside the U.S.

description: Newton's gravitational constant is shown to be a running coupling constant, much like the familiar running gauge couplings of the Standard Model. This implies that, in models with appropriate particle content, the true Planck scale, i.e. the scale at which quantum gravity effects become important, can have a value different from 10^19 GeV, which would be expected from naive dimensional analysis. Then, two scenarios involving this running effect are presented. The first one is a model which employs huge particle content to realize quantum gravity at the TeV scale in 4 dimensions, thereby solving the hierarchy problem of the Standard Model. Secondly, effects of the running of Newton's constant in grand unified theories are examined and shown to introduce new significant uncertainties in their predictions, but possibly also to provide better gauge coupling unification results in some cases.

description: This paper presents the results of a survey conducted in the Extension Service of the Israeli Ministry of Agriculture and Rural Development (IES). The organization has extensive internal knowledge of its organizational processes, and is characterized by information-intensive, knowledge-intensive processes. IS implementation, as part of the innovative culture of the organization, has long been an area of interest for both researchers and practitioners, with much emphasis on identifying the factors that lead to more and to less successful outcomes. Though it is easy to appreciate the important role culture plays in making an innovation successful, it is very difficult to change culture. Diffusion of usage of knowledge technology in agricultural extension service organizations is important because organizational culture is an important determinant of sustained innovation. In this paper, we examined two elements of organizational innovative culture in the IES. We believe that assimilating these elements of organizational culture will enable organizations to support and sustain innovative activities.

Genetic parameters of the physical and chemical wood properties of cool temperate eucalypts
Creators: name: Stackpole, DJ
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis comprises quantitative genetic studies of chemical and physical wood properties of the two main temperate plantation eucalypts in Australia, Eucalyptus globulus and E. nitens. The use of near-infrared spectroscopy models allowed the large-scale assessment of pulp yield and other wood chemical traits, including cellulose, lignin, extractives content, and lignin composition (syringyUguaiacyl ratio [S/G]), to compare with more readily assessed growth and density traits. The study of a fertiliser trial involving E. nitens clones showed that pulp yield was mainly affected by genetics. A large study was undertaken using a field trial of open-pollinated families collected from across the geographic range of E. globulus. This showed that wood properties were generally under medium to strong genetic control. There were significant differences between the geographic subraces of E. globulus, and narrow-sense heritability within subraces ranged from 0.15 to 0.51 across all traits, consistent with other studies of forest trees. A study of age trends in genetic parameters not only revealed the dynamic nature of heritability estimates but provided evidence of a changing genetic correlation between growth and density with age. Several discrepancies in the magnitude and direction of genetic correlations between traits were found compared to those reported in the literature, which were mostly smaller in sample size. Pulp yield increased with increasing latitude of provenance, suggesting that the economic worth of southern Tasmanian subraces for a lcraft pulpwood breeding objective had previously been underestimated. Pulp yield was shown to be highly positively correlated with cellulose and negatively correlated with lignin content. Lignin composition (S/G ratio) was highly positively correlated with pulp yield and also showed a clear latitudinal cline across the geographic range of E. globulus.

description: We verified operational approach based on direct measurement of entanglement degree for bipartite systems. In particular spectral distributions of single counts and coincidence for pure biphoton states generated by train of short pump pulses have been measured and entanglement quantifier calculated. The approach gives upper bound of entanglement stored in total biphoton states, which can reach extremely high value up to $10^{4}-10^{5}$.
