description: While the optical properties of thin metal films are well understood in the visible and near-infrared range, little has been done in the mid- and far-infrared region. Here we investigate ultra-thin gold films prepared on Si(111)(7 x 7) in UHV by measuring in the frequency range between 500 cm-1 and 7000 cm-1 and for temperatures between 300 K and 5 K. The nominal thickness of the gold layers ranges between one monolayer and 9 nm. The frequency and temperature dependences of the thicker films can be well described by the Drude model of a metal, when taking into account classical size effects due to surface scattering. The films below the percolation threshold exhibit a non-metallic behavior: the reflection increases with frequency and decreases with temperature. The frequency dependence can partly be described by a generalized Drude model. The temperature dependence does not follow a simple activation process. For monolayers we observe a transition between surface states around 1100 cm-1.

description: It is shown that for inhomogeneous Lie algebras $\frak{g}=\frak{s}\overrightarrow{\oplus}_Λ(\dim Λ)L_{1}$ satisfying the condition $\mathcal{N}(\frak{g})=1$, the only Casimir operator can be explicitly constructed from the Maurer-Cartan equations by means of wedge products. It is shown that this constraint imposes sharp bounds for the dimension of the representation $R$. The procedure is generalized to compute also the rational invariant of some Lie algebras.

description: Correlations between the quasi-periodic oscillations (QPOs) and the spectral power-law index have been reported for a number of black hole candidate sources and for four neutron star (NS) sources, 4U 0614+09, 4U 1608-52, 4U 1728-34 and Sco X-1. An examination of QPO frequencies and index relationship in Cyg X-2 is reported herein. The RXTE spectrum of Cyg X-2 can be adequately represented by a simple two-component model of Compton up-scattering with a soft photon electron temperature of about 0.7 keV and an iron K-line. Inferred spectral power-law index shows correlation with the low QPO frequencies. We find that the Thomson optical depth of the Compton cloud (CC) tau, in framework of spherical geometry, is in the range of ~4-6, which is consistent with the neutron star's surface being obscured. The NS high frequency pulsations are presumably suppressed as a result of photon scattering off CC electrons because of such high values of tau. We also point out a number of similarities in terms timing (presence of low and high frequency QPOs) and spectral (high CC optical depth and low CC plasma temperature) appearances between Cyg X-2 and Sco X-1.

Cosmic metal density evolution in neutral gas: insights from observations and cosmological simulations

description: We contrast the latest observations of the cosmic metal density in neutral gas ($ρ_{\rm met,neu}$) with three cosmological galaxy evolution simulations: L-GALAXIES 2020, TNG100, and EAGLE. We find that the fraction of total metals that are in neutral gas is $<40$ per cent at $3\lesssim{} z \lesssim{} 5$ in these simulations, whereas observations of damped Lyman-$α$ (DLA) systems suggest $\gtrsim{}85$ per cent. In all three simulations, hot, low-density gas is also a major contributor to the cosmic metal budget, even at high redshift. By considering the evolution in cosmic SFR density ($ρ_{\rm SFR}$), neutral gas density ($ρ_{\rm HI}$), and mean gas-phase metallicity ($[\langle{}{\rm M/H}\rangle{}]_{\rm neu}$), we determine two possible ways in which the $ρ_{\rm met,neu}$ observed in DLAs at high redshift can be matched by simulations: (a) the $ρ_{\rm SFR}$ at $z\gtrsim{}3$ is greater than inferred from current FUV observations, or (b) current high-redshift DLA metallicity samples have a higher mean host mass than the overall galaxy population. If the first is correct, TNG100 would match the ensemble data best, however there would be an outstanding tension between the currently observed $ρ_{\rm SFR}$ and $ρ_{\rm met,neu}$. If the second is correct, L-GALAXIES 2020 would match the ensemble data best, but would require an increase in neutral gas mass inside subhaloes above $z\sim{}2.5$. If neither is correct, EAGLE would match the ensemble data best, although at the expense of over-estimating $[\langle{}{\rm M/H}\rangle{}]_{\rm neu}$. Modulo details related to numerical resolution and HI mass modelling in simulations, these incompatibilities highlight current tensions between key observed cosmic properties at high redshift.

description: Surface adsorption of C$_{60}$ affects its chemical and electronic properties. Numerous studies have reported observation of bright and dark fullerenes on metal surfaces that suggest extensive surface reconstruction, however, the underpinning mechanism of the reconstruction remains under debate. Here we report tip-functionalised non-contact atomic force microscope (ncAFM) measurements which unambiguously reveal that C$_{60}$ fullerenes adsorb with three well-defined adsorption heights on the Cu(111) surface, consistent with theoretical reports of top-layer hollow site, single-atom vacancies, and surface nanopits. Using single molecule resolution $Δf(z)$ measurements we identify well defined adsorption heights specific to each site, confirming the presence of a complex vacancy model for C$_{60}$ monolayers on metal surfaces.
The molecular cloning of Cellulomonas fimi cellulase genes
Creators: name: Whittle, Daniel Joseph
Publisher: name: University of British Columbia
Year: 2010

description: Recombinant DNA techniques were used to clone and isolate Cellulo- monas fimi cellulase genes. A sensitive and simple immunoassay was developed to screen Escherichia coli transformed with recombinant plasmids carrying cellulase genes. The screening procedure is based on binding cellulases and other proteins released from lysed clones to CNBr-acti- vated paper. The paper is treated with anti-cellulase antibody and the antigen-antibody complex is detected by autoradiography using ¹²⁵I-labeled protein A from Staphylococcus aureus. This- immunoassay, was used to identify recombinant plasmids containing strains, carrying at least two different cellulase genes. The enzymes present in extracts of E. coli cellulase clones were active in catalysing the hydrolysis of carboxymethy1 eel 1ulose as indicated by the production of reducing sugars. Osmotic shock treatment of one E. coli cellulase clone revealed that the majority of the cellulase enzyme synthesized by this clone was transported to the periplasmic space. Cellulase encoding plasmids were characterized by the presence of either a 6.6 or a 5.0 kilobase C. fimi DNA gene fragment.

We present, the first analytic expressions for reduced density matrices of n spins in a chain of length L (for n<=6 and arbitrary but odd L) of a truly interacting model. The entanglement entropy, the moments of the reduced density matrix, and its spectrum are then easily derived. We explicitely construct the "entanglement Hamiltonian" as the logarithm of this matrix. Exploiting the degeneracy of the ground-state, we find the scaling behavior of entanglement of the zero-temperature mixed state.

description: We present the first multi-wavelength (near-infrared; $1.1 - 2.4$ $μm$) imaging of HD 36546's debris disk, using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system coupled with the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS). As a 3-10 Myr old star, HD 36546 presents a rare opportunity to study a debris disk at very early stages. SCExAO/CHARIS imagery resolves the disk over angular separations of $ρ\sim 0.25" - 1.0"$ (projected separations of $\rm{r_{proj}} \sim 25 - 101$ $\rm{au}$) and enables the first spectrophotometric analysis of the disk. The disk's brightness appears symmetric between its eastern and western extents and it exhibits slightly blue near-infrared colors on average (e.g. $J-K =-0.4\pm0.1$) $-$ suggesting copious sub-micron sized or highly porous grains. Through detailed modeling adopting a Hong scattering phase function (SPF), instead of the more common Henyey-Greenstein function, and using the differential evolution optimization algorithm, we provide an updated schematic of HD 36546's disk. The disk has a shallow radial dust density profile ($α_{in} \approx 1.0$ and $α_{out} \approx -1.5$), a fiducial radius of $r_0 \approx 82.7$ au, an inclination of $i \approx 79.1^\circ$, and a position angle of $\rm PA \approx 80.1^\circ$. Through spine tracing, we find a spine that is consistent with our modeling, but also with a "swept-back wing" geometry. Finally, we provide constraints on companions, including limiting a companion responsible for a marginal Hipparcos-Gaia acceleration to a projected separation of $\lesssim 0.2''$ and to a minimum mass of $\lesssim 11$ $\rm M_{Jup}$.

Large-Scale Structure of Short-Lived LymanαEmitters

description: Recently discovered large-scale structure of LyαEmitters (LAEs) raises a novel challenge to the cold dark matter (CDM) cosmology. The structure is extended over more than 50 Mpc at redshift z=3.1, and exhibits a considerably weak angular correlation. Such properties of LAE distributions appear to be incompatible with the standard biased galaxy formation scenario in the CDM cosmology. In this paper, by considering the possibility that LAEs are short-lived events, we attempt to build up the picture of LAEs concordant with the CDM cosmology. We find that if the lifetime of LAEs is as short as (6.7 \pm 0.6) \times 10^7 yr, the distributions of simulated galaxies successfully match the extension and morphology of large-scale structure of LAEs at z=3.1, and also the weak angular correlation function. This result implies that LAEs at z=3.1 do not necessarily reside in high density peaks, but tends to be located in less dense regions, in a different way from the expectation by the standard biased galaxy formation scenario. In addition, we make a prediction for the angular correlation function of LAEs at redshifts higher than 3. It is found that the prediction deviates from that by the standard biased galaxy formation scenario even at redshifts 4 < z < 6.

description: Structural, electronic, and magnetic properties of undoped and aliovalent-ion (Ca, F)-doped LaOFeP, which undergo superconducting transitions at transition temperatures (Tc) 4-7 K [Kamihara et al, J. Am. Chem. Soc. 128, 10012, (2006)], were investigated. Tc of the samples varied from 2.4 to 5.5 K in the undoped samples, and was increased up to ~7 K by Ca- and F-doping. The Tc increases are correlated with a decrease in the lattice volume. LaOFeP exhibits paramagnetism in the normal conducting state. Photoemission spectroscopy combined with first-principle band calculations clarified that Fe 3d (dz2 + (dxz, dyz)) orbitals hybridized with P 3p to form a Fermi surface. The band calculations also suggest that the 3d electron of the Fe in LaOFeP is basically in the low-spin configuration, and that the spin moment of LaOFeP is almost quenched, leading to the paramagnetism of the itinerant electrons.

description: The current prospects for U.S. agriculture, particularly for its export sector, are examined in the light of the new 1985 Farm Bill. After having taken stock of the situation in the 1970s and the developments in the 1980s so far, the paper goes on to define the problems in U.S. agriculture as declining equity, worsening of debt asset ratios and a growing incidence of non-performing farm loans jeopardising the life of many rural banks. The main thrust of the argument is that for the survival and long-term well being of U.S. agriculture, liberalisation of trade would be a most efficient strategy for the world market as a whole.

Occupied states exhibit a sizeable downward energy shift as the island size decreases. The position of the occupied states also significantly changes across the islands. Atomic-scale simulations and ab inito calculations demonstrate that the driving force for the observed shift is related to size-dependent mesoscopic relaxations in the nanoislands.

Subjects: Farm Management

description: This paper examines the realities of practical farming within the economic environment created by the E.E.C. policies. The C.A.P. expenditure is rising inexorably and catastrophically primarily because of surplus production. This development is totally unacceptable and has to be resolved. It is argued that despite the persistent pockets of hunger that exist in the world, the situation is that of a global structural surplus and imbalance. To remedy the problem farmers must be involved in the market place, not isolated from it; and production and exports have to be coordinated on a more international basis.

description: We report the discovery of the largest giant radio galaxy, J1420-0545: a FR type II radio source with an angular size of 17.4' identified with an optical galaxy at z=0.3067. Thus, the projected linear size of the radio structure is 4.69 Mpc (if we assume that H_{0}=71 km\s\Mpc, Omega_{m}=0.27, and Omega_Λ=0.73). This makes it larger than 3C236, which is the largest double radio source known to date. New radio observations with the 100 m Effelsberg telescope and the Giant Metrewave Radio Telescope, as well as optical identification with a host galaxy and its optical spectroscopy with the William Herschel Telescope are reported. The spectrum of J1420-0545 is typical of elliptical galaxies in which continuum emission with the characteristic 4000A discontinuity and the H and K absorption lines are dominated by evolved stars. The dynamical age of the source, its jets' power, the energy density, and the equipartition magnetic field are calculated and compared with the corresponding parameters of other giant and normal-sized radio galaxies from a comparison sample. The source is characterized by the exceptionally low density of the surrounding IGM and an unexpectedly high expansion speed of the source along the jet axis. All of these may suggest a large inhomogeneity of the IGM.

description: Quantifying the efficiency of dust destruction in the interstellar medium (ISM) due to supernovae (SNe) is crucial for the understanding of galactic dust evolution. We present 3D hydrodynamic simulations of an SN blast wave propagating through the ISM. The interaction between the forward shock of the remnant and the surrounding ISM leads to destruction of ISM dust by the shock heated gas. We consider the dust processing due to ion sputtering, accretion of atoms/molecules and grain-grain collisions. Using 2D slices from the simulation timeseries, we apply post-processing calculations using the Paperboats code. We find that efficiency of dust destruction depends strongly on the rate of grain shattering due to grain-grain collisions. The effective dust destruction is similar to previous theoretical estimates when grain-grain collisions are omitted, but with grain shattering included, the net destruction efficiency is roughly one order of magnitude higher. This result indicates that the dust destruction rate in the ISM may have been severely underestimated in previous work, which only exacerbates the dust-budget crises seen in galaxies at high redshifts.

The Economic and Policy Frameworks for Agriculture in the USSR and People's Republic of China

Year: 1986
Subjects: Agricultural and Food Policy

description: Both the USSR and China have considered policy reforms that would affect farm management decisions and the performance of agriculture. Reforms in the USSR have had little effect upon the agricultural system and bureaucratic interventions with farm management may have increased. The Chinese reforms have been radical ones. The commune system - the basic structure of the socialized agriculture - has been abolished. Land has been assigned to individual households for 15 years. For most products compulsory deliveries of farm products have been abolished. Between 1978 and 1984 agricultural production in the USSR increased by just 6 percent; in China the increase was 50 percent. At least half of the increase in farm production in China can be attributed to the reforms.

description: Graphitic nanostructures, e.g. carbon nanotubes (CNT) and graphene, have been proposed as ideal materials for spin conduction[1-7]; they have long electronic mean free paths[8] and small spin-orbit coupling[9], hence are expected to have very long spin-scattering times. In addition, spin injection and detection in graphene opens new opportunities to study exotic electronic states such as the quantum Hall[10,11] and quantum spin Hall[9] states, and spin-polarized edge states[12] in graphene ribbons. Here we perform the first non-local four-probe experiments[13] on graphene contacted by ferromagnetic Permalloy electrodes. We observe sharp switching and often sign-reversal of the non-local resistance at the coercive field of the electrodes, indicating definitively the presence of a spin current between injector and detector. The non-local resistance changes magnitude and sign quasi-periodically with back-gate voltage, and Fabry-Perot-like oscillations[6,14,15] are observed, consistent with quantum-coherent transport. The non-local resistance signal can be observed up to at least T = 300 K.

description: In the framework of type II seesaw mechanism we discuss the number of sterile right-handed Majorana neutrinos being the warm dark matter (WDM). When the type II seesaw mass term $M_ν^{II}$ is far less than the type I seesaw mass term $M_ν^{I}$, only one of three sterile neutrinos may be the WDM particle. On the contrary, the WDM particles may contain all sterile neutrinos. If $M_ν^{II} \sim M_ν^{I}$, the allowed number is not more than $N - 1$ for $N$ sterile neutrinos. It is worthwhile to stress that three different types of neutrino mass spectrum are permitted when $M_ν^{II} \gg M_ν^{I}$ and $M_ν^{II} \sim M_ν^{I}$.

description: The importance of farming to the Dutch economy is highlighted and the need to produce more from less land is emphasised. The preservation and development of competitive agricultural enterprises, based on private family capital, is of vital importance to the rural areas in Holland. Further research is needed to develop agricultural production methods which do not conflict with the objectives of maintaining a desirable environment. There is also an urgent need to find new uses for agricultural products. On the production side, the immediate priority is to control and limit production costs, bearing in mind that an important part of the productivity gain would go to strategic investments.

Die Publikation ist im Rahmen des vom österreichischen FWF geförderten Forschungsprojekts Tausend Jahre ukrainische Sprachgeschichte in Galizien [2] an der Universität Wien entstanden. Hibels Buch hebt sich von Überblicksdarstellungen zur Minderheiten- oder Sprachpolitik gegenüber den Ukrainern im Polen der Zwischenkriegszeit vor allem durch ihre eigenständige Konzeption und eine größere Detailtiefe ab.

description: Niezbyt obfity zasób polskojęzycznych tekstów z zakresu studiów nad zwierzętami został wzbogacony o tłumaczenie obfitego tomu autorstwa Erica Barataya, francuskiego historyka i eseisty. Éric Baratay w „Zwierzęcym punkcie widzenia" stara się uchwycić tytułowy punkt widzenia zwierząt i opowiedzieć historię z ich perspektywy. Dla czytelników zaznajomionych z animal studies nie jest to zapewne zaskakujący zabieg, ale dla wszystkich pozostałych może być tak zaskoczeniem jak i ciekawą intelektualną przygodą. Jednak czy jedynie o intelektualne ćwiczenie tu chodzi? Książka boleśnie uświadamia nie zawsze chlubną rolę człowieka w relacji z innymi zwierzętami, by wymienić tylko okrucieństwo czy masowe uśmiercanie. Zapewne nie tylko pełen empatii czytelnik może zostać porażony ogromem cierpienia, jakiego z woli człowieka doświadczały i doświadczają zwierzęta. Historia z uwzględnieniem zwierzęcego punktu widzenia to bowiem historia niewyobrażalnego cierpienia dlatego wzajemne współistnienie świata ludzkiego i zwierzęcego wymaga gruntownego przemyślenia. I to ta inna możliwa przyszłość wydaje się ostatecznym celem na nowo opowiedzianej historii.

description: Correlations and clustering are of great importance in the study of the Nuclear Equation of State. Information on these items/aspects can be obtained using Heavy-Ion reactions which are described by dynamical theories. We propose a dataset that will be useful for improving the description of light cluster production in transport model approaches. The dataset combines published and new data and is presented in a form that allows direct comparison of the experiment with theoretical predictions. The dataset is ranging in bombarding energy from 32 to 1930 A MeV. In constructing this dataset we put in evidence the existence of a change in the light cluster production mechanism that corresponds to a peak in deuteron production.

description: Na rynku wydawniczym możemy znaleźć liczne publikacje dotyczące stanu i perspektyw polskiej polityki zagranicznej po wejściu do NATO i Unii Europejskiej [1]. Artykuły na ten temat występują też w pracach podsumowujących naszą obecność w strukturach euroatlantyckich [2]. Niniejsza publikacja wpisuje się w ten swoisty podsumowujący nurt w polskim piśmiennictwie. Jak zaznaczono we wstępie, jest ona rezultatem badań statutowych realizowanych w Instytucie Stosunków Międzynarodowych Uniwersytetu Warszawskiego oraz konferencji naukowej zorganizowanej w 2009 roku przez Wydział Dziennikarstwa i Nauk Politycznych wspomnianej uczelni. Tym samym trudno się dziwić, iż ma ona wszystkie zalety (specjalizacja autorów) i wady (zróżnicowany poziom i forma) monografii wieloautorskiej.

description: The recursive least-squares algorithm with $\ell_1$-norm regularization ($\ell_1$-RLS) exhibits excellent performance in terms of convergence rate and steady-state error in identification of sparse systems. Nevertheless few works have studied its stochastic behavior, in particular its transient performance. In this letter, we derive analytical models of the transient behavior of the $\ell_1$-RLS in the mean and mean-square sense. Simulation results illustrate the accuracy of these models.

description: Książka pod redakcją Stephana Scholza, Maren Röger i Billa Nivena jest imponującym przeglądem różnych form upamiętnienia ucieczki i wypędzenia w niemieckiej kulturze powojennej – w RFN, NRD i po zjednoczeniu. Zawiera 35 tekstów, napisanych wedle analogicznego schematu i omawiających najróżniejsze zjawiska związane ze zbiorową pamięcią o wysiedleniach – począwszy od lokalnych praktyk, przywiązanych do konkretnych miejsc i osób, a skończywszy na elementach kultury masowej. Są więc teksty o ustnych opowieściach, nazwach ulic, pomnikach, mapach, muzyce, jubileuszach, radiu, prasie lokalnej i ponadregionalnej, filmie, internecie itd. W języku polskim trudno znaleźć określenie na formę Handbucha, który jest znacznie bardziej rozbudowany niż encyklopedie i leksykony, wyjaśnia zjawiska dogłębniej i operuje większą liczbą przykładów, ale też jest nieporównanie bardziej spójny, konsekwentny i kompletny niż „zwyczajne" tomy zbiorowe.

description: Using the coupled-cluster method for infinite lattices and the exact diagonalization method for finite lattices, we study the influence of an exchange anisotropy Delta on the ground-state phase diagram of the spin-1/2 frustrated J1-J2 XXZ antiferromagnet on the square lattice. We find that increasing Delta>1 (i.e. an Ising type easy-axis anisotropy) as well as decreasing Delta<1 (i.e. an XY type easy-plane anisotropy) both lead to a monotonic shrinking of the parameter region of the magnetically disordered quantum phase. Finally, at Delta~1.9 this quantum phase disappears, whereas in pure XY limit (Delta=0) there is still a narrow region around J2 =0.5J1 where the quantum paramagnetic ground-state phase exists.

Marketing Management - Beef
Creators: name: Gilbreath, Zay W.
Publisher: name: Unknown
Year: 1986
Subjects: subject: Marketing
subject: FOS: Economics and business
subject: Livestock Production/Industries

description: For far too long farmers have been production oriented, paying little attention to the marketing of their products. In the current economic and political environment that is no longer sufficient to survive. A farmer must know, not only how to produce but what it costs to produce, what risks are involved, which risks can be avoided; and, probably most important, what marketing alternatives are available. This paper shows the strategies and detailed requirements of marketing management of a beef farm from the High Plains of the USA.

Marketing Management - Corn & Soybeans
Creators: name: Urevig, Edgar M.
Publisher: name: Unknown
Year: 1986
Subjects: subject: Marketing
subject: FOS: Economics and business
subject: Crop Production/Industries

description: Marketing of agricultural products is a managerial function which hitherto has not received the same emphasis as given to production. The fundamental elements of supply, demand and government intervention determine the policies and their trends. Even if all the possible information on factors that affect the price of grains were available, one farmer's interpretation of it is very likely to be different from that of another. This paper outlines the practical use of charting of prices, profitability and views about the future market conditions for effective market management. It illustrates their use in the market management of selling corn and soybeans in the USA.

description: We derive the lower and upper bounds on the entanglement of a given multipartite superposition state in terms of the entanglement of the states being superposed. The first entanglement measure we use is the geometric measure, and the second is the q-squashed entanglement. These bounds allow us to estimate the amount of the multipartite entanglement of superpositions. We also show that two states of high fidelity to one another do not necessarily have nearly the same q-squashed entanglement.

Land Values and Appraisals - Australia
Creators: name: Collett, P.
Publisher: name: Unknown
Year: 1986
Subjects: Land Economics/Use

description: Australian land values are compared with that of U.S.A. and Europe. This comparison is made difficult by the fact that there are differences amongst these countries with regard to government subsidies, taxation laws, farming techniques and methods, land titles, manpower management practices and the general weather conditions. However some meaningful comparisons can be made about land values in different countries, and an indication can be obtained about comparative return to investment.

description: Recenzowana monografia pod redakcją Andrzeja Dorosza to zbiór tekstów opisujących wybrane sektory gospodarki czy obszary działalności na tle globalnego kryzysu finansowego. (...) W tym sensie recenzowana monografia zwiększa zakres wiedzy na temat oddziaływania globalnego kryzysu finansowego na działalność wybranych sfer gospodarki z sektora prywatnego i publicznego, a także na styku tych sektorów (partnerstwo publiczno-prywatne). Zasięg geograficzny przestawionych problemów dotyczy skali światowej (globalnej) (analiza roli Międzynarodowy Fundusz Walutowy (MFW) i specjalnych praw ciągnienia (SDR; ang. Special Drawing Rights) w kryzysie), międzynarodowej (strefa euro), ogólnopolskiej lub lokalnej. Podjęcie problematyki monografii należy uznać za trafne. Ujęcie problemu globalnego kryzysu finansowego z różnych perspektyw geograficznych należy również ocenić pozytywnie, ponieważ pozwala przejść od ogółu do szczegółu, od nakreślenia tła kryzysu w postaci jego przyczyn, mechanizmu i przebiegu, aż po wpływ na sektor publiczny, w tym finanse publiczne i sektor prywatny, przedsiębiorstwa i lokalną aktywność gospodarczą.
Land Values and Appraisals - Denmark
Creators: name: Jorgensen, A.
Publisher: name: Unknown
Year: 1986
Subjects: Land Economics/Use

description: The price of farm land went up strongly during the 1970's followed by a fall in the early 1980’s due to a combination of factors; among which economic return in agriculture and variation in capital costs are the major ones. The combined effect of inflation, taxation and capital support programmes has created uncertainty about the real cost of capital, affecting the stability of land markets. The real estate markets should be made more transparent and farmers should be given better information about the conditions for farming as a basis for their planning.
