description: We study the entanglement entropy between (possibly distinct) topological phases across an interface using an Abelian Chern-Simons description with topological boundary conditions (TBCs) at the interface. From a microscopic point of view, these TBCs correspond to turning on particular gapping interactions between the edge modes across the interface. However, in studying entanglement in the continuum Chern-Simons description, we must confront the problem of non-factorization of the Hilbert space, which is a standard property of gauge theories. We carefully define the entanglement entropy by using an extended Hilbert space construction directly in the continuum theory. We show how a given TBC isolates a corresponding gauge invariant state in the extended Hilbert space, and hence compute the resulting entanglement entropy. We find that the sub-leading correction to the area law remains universal, but depends on the choice of topological boundary conditions. This agrees with the microscopic calculation of \cite{Cano:2014pya}. Additionally, we provide a replica path integral calculation for the entropy. In the case when the topological phases across the interface are taken to be identical, our construction gives a novel explanation of the equivalence between the left-right entanglement of (1+1)d Ishibashi states and the spatial entanglement of (2+1)d topological phases.

description: This paper is devoted to the study of the statistical mechanics of trapped gravitons obtained by 'trapping' a spherical gravitational wave in a box. As a consequence, a discrete spectrum dependent on the Legendre index $\ell$ similar to the harmonic oscillator one is obtained and a statistical study is performed. The mean energy $$ results as a sum of two discrete Planck distributions with different dependent frequencies. As an important application, we derive the semiclassical Bekenstein-Hawking entropy formula for a static Schwarzschild black hole by only requiring that the black hole internal energy $U$ is provided by its ADM rest energy, without invoking particular quantum gravity theories. This seriously suggests that the interior of a black hole can be composed of trapped gravitons at a thermodynamical temperature proportional by a factor $\simeq 2$ to the horizon temperature $T_h$.

Quasar Lenses and Galactic Streams: Outlier Selection and GAIA Multiplet Detection

description: I describe two novel techniques originally devised to select strongly lensed quasar candidates in wide-field surveys. The first relies on outlier selection in optical and mid-infrared magnitude space; the second combines mid-infrared colour selection with GAIA spatial resolution, to identify multiplets of objects with quasar-like colours. Both methods have already been applied successfully to the SDSS, ATLAS and DES footprints: besides recovering known lenses from previous searches, they have led to new discoveries, including quadruply lensed quasars, which are rare within the rare-object class of quasar lenses. As a serendipitous by-product, at least four candidate Galactic streams in the South have been identified among foreground contaminants. There is considerable scope for tailoring the WISE-GAIA multiplet search to stellar-like objects, instead of quasar-like, and to automatically detect Galactic streams.

description: We propose that there is a regime of quantum gravity phenomena, for the case that the cosmological constant is small and positive, which concerns phenomena at temperatures below the deSitter temperature, or length scales larger than the horizon. We observe that the standard form of the equivalence principle does not apply in this regime; we consider instead that a weakened form of the equivalence principle might hold in which the ratio of gravitational to inertial mass is a function of environmental and global parameters. We consider possible principles to determine that function. These lead to behaviour that, in the limit of hbar to zero and the speed of light is taken to infinity, reproduces the modifications of Newtonian dynamics first proposed by Milgrom. Thus MOND is elucidated as coding the physics of a novel regime of quantum gravity phenomena. We propose also an effective description of this regime in terms of a bi-metric theory, valid in the approximation where the metric is static. This predicts a new effect, which modifies gravity for radial motions.

Towards an industrial pattern: historical development of livestock and stockbreeding in Cantabrian Spain
Creators: name: Aragón Ruano, Álvaro
Publisher: name: History Factory
Year: 2022

description: The aim of this paper is to analyse the effects in the long-term of the evolution of livestock and stockbreeding in Cantabrian Spain. Until the 17th century, when American crops spread at different rates throughout the Cantabrian region, stockbreeding was based on an extensive pattern. But, since then, due to, above all, maize-growing as well as the expansion of grasslands and meadows, stockbreeding shifted towards intensive methods, which allowed the modernisation of the sector, by means of technological progress and the introduction of industrial exploitation systems from the 19th century onwards, even though different degrees of specialisation (meat, milk, etc.) were implemented, depending on the area. For that purpose, we are going to utilize the significant amount of recent literature available

description: We demonstrate the presence of chaos in stochastic simulations that are widely used to study biodiversity in nature. The investigation deals with a set of three distinct species that evolve according to the standard rules of mobility, reproduction and predation, with predation following the cyclic rules of the popular rock, paper and scissors game. The study uncovers the possibility to distinguish between time evolutions that start from slightly different initial states, guided by the Hamming distance which heuristically unveils the chaotic behavior. The finding opens up a quantitative approach that relates the correlation length to the average density of maxima of a typical species, and an ensemble of stochastic simulations is implemented to support the procedure. The main result of the work shows how a single and simple experimental realization that counts the density of maxima associated with the chaotic evolution of the species serves to infer its correlation length. We use the result to investigate others distinct complex systems, one dealing with a set of differential equations that can be used to model a diversity of natural and artificial chaotic systems, and another one, focusing on the ocean water level.

Length-Weight Relationship and Fulton’s Condition Factor of the Nile Tilapia (Oreochromis niloticus L., 1758) in Lake Chamo, Ethiopia
Creators: name: Shija, Buchale Shishitu
Publisher: name: Journal of Agriculture and Environmental Sciences

description: The objectives of the study were to determine the length-weight relationship and Fulton’s condition factor of O. niloticus in Lake Chamo, Southern region of Ethiopia. Data for total length (TL), total weight (TW) and sex were collected from 5,778 fish samples (3577 females and 2201 males) for nine months (February to October 2018) from commercial fishery of Lake Chamo. The collected data were summarized using descriptive statistics (graphs and tables) and analyzed with the application of Microsoft Excel 2010 and SPSS Software. The length-weight relationship was calculated using power function and obtained as TW = 0.0112*TL3.14, (R2 = 0.96), TW = 0.0102*TL3.19, (R2 = 0.98) and TW = 0.0102*TL3.18, (R2 = 0.97) for male, female and pooled sexes, respectively. The b value in this study was greater than the cubic (b > 3) value and indicates that both males and females of O. niloticus in Lake Chamo followed positive allometric growth pattern. The average Fulton’s condition factor (K) value for male, female and combined sex was 1.78, 1.96 and 1.85, respectively. The one-way ANOVA (P > 0.05) revealed that Fulton’s condition factor by month’s interaction was insignificant. But the condition factor of both sexes in Lake Chamo was significantly different (ANOVA, p < 0.05). There was highly significant differences between sexes interaction (t-test, P = 0.000) which indicates the presence of temporal variation between both sexes in Fulton’s condition factor. All the values of Fulton’s condition factors of male, female and combined sex of O. niloticus were above 1.6 and indicates that O. niloticus of Lake Chamo was in a very good condition throughout the study period. Future studies including other species of fish are also recommended

Year: 2017
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Geodesic bulk diagrams were recently shown to be the geometric objects which compute global conformal blocks. We show that this duality continues to hold in $p$-adic AdS/CFT, where the bulk is replaced by the Bruhat-Tits tree, an infinite regular graph with no cycles, and the boundary is described by $p$-adic numbers, rather than reals. We apply the duality to evaluate the four-point function of scalar operators of generic dimensions using tree-level bulk diagrams. Relative to standard results from the literature, we find intriguing similarities as well as significant simplifications. Notably, all derivatives disappear in the conformal block decomposition of the four-point function. On the other hand, numerical coefficients in the four-point function as well as the structure constants take surprisingly universal forms, applicable to both the reals and the $p$-adics when expressed in terms of local zeta functions. Finally, we present a minimal bulk action with nearest neighbor interactions on the Bruhat-Tits tree, which reproduces the two-, three-, and four-point functions of a free boundary theory.

description: We study special circle bundles over two elementary moduli spaces of meromorphic quadratic differentials with real periods denoted by $\mathcal Q_0^{\mathbb R}(-7)$ and $\mathcal Q^{\mathbb R}_0([-3]^2)$. The space $\mathcal Q_0^{\mathbb R}(-7)$ is the moduli space of meromorphic quadratic differentials on the Riemann sphere with one pole of order 7 with real periods; it appears naturally in the study of a neighbourhood of the Witten's cycle $W_1$ in the combinatorial model based on Jenkins-Strebel quadratic differentials of $\mathcal M_{g,n}$. The space $\mathcal Q^{\mathbb R}_0([-3]^2)$ is the moduli space of meromorphic quadratic differentials on the Riemann sphere with two poles of order at most 3 with real periods; it appears in description of a neighbourhood of Kontsevich's boundary $W_{-1,-1}$ of the combinatorial model. The application of the formalism of the Bergman tau-function to the combinatorial model (with the goal of computing analytically Poincare dual cycles to certain combinations of tautological classes) requires the study of special sections of circle bundles over $\mathcal Q_0^{\mathbb R}(-7)$ and $\mathcal Q^{\mathbb R}_0([-3]^2)$; in the case of the space $\mathcal Q_0^{\mathbb R}(-7)$ a section of this circle bundle is given by the argument of the modular discriminant. We study the spaces $\mathcal Q_0^{\mathbb R}(-7)$ and $\mathcal Q^{\mathbb R}_0([-3]^2)$, also called the spaces of Boutroux curves, in detail, together with corresponding circle bundles.

description: The range of currently proposed active galactic nucleus (AGN) far-infrared templates results in uncertainties in retrieving host galaxy information from infrared observations and also undermines constraints on the outer part of the AGN torus. We discuss how to test and reconcile these templates. Physically, the fraction of the intrinsic AGN IR-processed luminosity compared with that from the central engine should be consistent with the dust-covering factor. In addition, besides reproducing the composite spectral energy distributions (SEDs) of quasars, a correct AGN IR template combined with an accurate library of star-forming galaxy templates should be able to reproduce the IR properties of the host galaxies, such as the luminosity-dependent SED shapes and aromatic feature strengths. We develop tests based on these expected behaviors and find that the shape of the AGN intrinsic far-IR emission drops off rapidly starting at $\sim20~μ$m and can be matched by an Elvis et al. (1994)-like template with minor modification. Despite the variations in the near- to mid-IR bands, AGNs in quasars and Seyfert galaxies have remarkably similar intrinsic far-IR SEDs at $λ\sim 20$-$100~μ$ m, suggesting similar emission character of the outermost region of the circumnuclear torus. The variations of the intrinsic AGN IR SEDs among the type-1 quasar population can be explained by the changing relative strengths of four major dust components with similar characteristic temperatures, and there is evidence for compact AGN-heated dusty structures at sub-kpc scales in the far-IR.

Simplified dark matter models in the light of AMS-02 antiproton data
Creators: name: Li, Tong
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In this work we perform an analysis of the recent AMS-02 antiproton flux and the antiproton-to-proton ratio in the framework of simplified dark matter models. To predict the AMS-02 observables we adopt the propagation and injection parameters determined by the observed fluxes of nuclei. We assume that the dark matter particle is a Dirac fermionic dark matter, with leptophobic pseudoscalar or axialvector mediator that couples only to Standard Model quarks and dark matter particles. We find that the AMS-02 observations are consistent with the dark matter hypothesis within the uncertainties. The antiproton data prefer a dark matter (mediator) mass in the 700 GeV--5 TeV region for the annihilation with pseudoscalar mediator and greater than 700 GeV (200 GeV--1 TeV) for the annihilation with axialvector mediator, respectively, at about 68% confidence level. The AMS-02 data require an effective dark matter annihilation cross section in the region of 1x10^{-25} -- 1x10^{-24} (1x10^{-25} -- 4x10^{-24}) cm^3/s for the simplified model with pseudoscalar (axialvector) mediator. The constraints from the LHC and Fermi-LAT are also discussed.

A Paradigm Shift from Area-Led to Productivity-Led Production of Maize in Nigeria

Publisher: name: Journal of Agriculture and Environmental Sciences
Year: 2020

description: Unlike in the past when production performance was judged from the area, in recent time's growth performance is hinged on productivity. In Nigeria, increasing maize production through area expansion is no longer feasible owing to pressure on demand for arable limited land for allied sectors, urbanization, industrialization etc. thus threatening sustainable maize production which is the precursor for self-sufficiency in maize production. It is in lieu of this that the present research empirically examined the ex-post and ex-ante production trend of maize production in Nigeria. Time series data that spanned for 58 years (1961-2018) and covered production, area, yield and crop prices were used. The data were sourced from the FAO database and the collected data were analyzed using both descriptive and inferential statistics. The empirical evidence showed that maize production is not sustainable as area growth rate predominates in increasing the production growth rate of maize in the studied area. In addition, it was observed that variability in the production of maize owes majorly to uncertainty viz. weather vagaries. Furthermore, weather vagaries viz. drought and flood; and non-remunerative price of maize affected the supply response of maize. In a decade ahead, a deficit in the supply of maize is very imminent which will be owed to poor productivity, thus affecting the food security of maize in the studied area. Thus, the onus lies on the policymakers to invest adequately on technology and infrastructure in order to achieve a sustainable production of maize that will guarantee maize food security in the country.

description: In this work, we study the Friedmann-Robertson-Walker cosmology in which a Chaplygin gas is coupled to a non-linear scalar field in the framework of the Hořava-Lifshitz theory. In writing the action of the matter part, we use the Schutz's formalism so that the only degree of freedom of the Chaplygin gas plays the role of an evolutionary parameter. In a minisuperspace perspective, we construct the Lagrangian for this model and show that in comparison with the usual Einstein-Hilbert gravity, there are some correction terms coming from the Hořava theory. In such a set-up and by using of some approximations the classical dynamics of the model is investigated and some discussions about their possible singularities are presented. We then deal with the quantization of the model in the context of the Wheeler-DeWitt approach of quantum cosmology to find the cosmological wave function. We use the resulting wave functions to investigate the possibility of the avoidance of classical singularities due to quantum effects.

description: We compute the dielectric response of glasses starting from a microscopic system-bath Hamiltonian of the Zwanzig-Caldeira-Leggett type and using an ansatz from kinetic theory for the memory function in the resulting Generalized Langevin Equation. The resulting framework requires the knowledge of the vibrational density of states (DOS) as input, that we take from numerical evaluation of a marginally-stable harmonic disordered lattice, featuring a strong boson peak (excess of soft modes over Debye $\simω_{p}^{2}$ law). The dielectric function calculated based on this ansatz is compared with experimental data for the paradigmatic case of glycerol at $T\lesssim T_{g}$. Good agreement is found for both the reactive (real part) of the response and for the $α$-relaxation peak in the imaginary part, with a significant improvement over earlier theoretical approaches, especially in the reactive modulus. On the low-frequency side of the $α$-peak, the fitting supports the presence of $\sim ω_{p}^{4}$ modes at vanishing eigenfrequency as recently shown in [Phys. Rev. Lett. 117, 035501 (2016)]. $α$-wing asymmetry and stretched-exponential behaviour are recovered by our framework, which shows that these features are, to a large extent, caused by the soft boson-peak modes in the DOS.

description: Oggi le città sono caratterizzate da una crisi che non è solo economica ma anche ecologica e sociale e superarla vuol dire tener conto di tutti i fattori contemporaneamente.
La crisi sociale trova una riposta nella coabitazione che, tuttavia, da sola non basta. La crisi economica potrebbe trovare una soluzione nella "residenza temporanea", simbolo della flessibilità insita nella società contemporanea. La crisi ecologica trova un riscontro nell'Agrivillaggio, un nuovo quartiere agricolo ai margini delle città caratterizzato da un nuovo modo di abitare e di vivere all'insegna della sostenibilità economica ecologica e sociale.
L'insieme di questi tre fattori (coabitazione+temporaneità+agrivillaggio) può portare ad un nuovo sistema urbano grazie al quale, oltre a risolvere le questioni sociali, si registrano ottimi riscontri nell'ambito della valorizzazione dei paesaggi periurbani e della riduzione del consumo di suolo.

description: The concept of correlation is central to all approaches that attempt the description of many-body effects in electronic systems. Multipartite correlation is a quantum information theoretical property that is attributed to quantum states independent of the underlying physics. In quantum chemistry, however, the correlation energy (the energy not seized by the Hartree-Fock ansatz) plays a more prominent role. We show that these two different viewpoints on electron correlation are closely related. The key ingredient turns out to be the energy gap within the symmetry-adapted subspace. We then use a few-site Hubbard model and the stretched H$_2$ to illustrate this connection and to show how the corresponding measures of correlation compare.

description: In the top-down holographic model of QCD based on D4/D8-branes in type IIA string theory and some of the bottom up models, the low energy effective theory of mesons is described by a 5 dimensional Yang-Mills-Chern-Simons theory in a certain curved background with two boundaries. The 5 dimensional Chern-Simons term plays a crucial role to reproduce the correct chiral anomaly in 4 dimensional massless QCD. However, there are some subtle ambiguities in the definition of the Chern-Simons term for the cases with topologically non-trivial gauge bundles, which include the configurations with baryons. In particular, for the cases with three flavors, it was pointed out by Hata and Murata that the naive Chern-Simons term does not lead to an important constraint on the baryon spectrum, which is needed to pick out the correct baryon spectrum observed in nature. In this paper, we propose a formulation of well-defined Chern-Simons term which can be used for the cases with baryons, and show that it recovers the correct baryon constraint as well as the chiral anomaly in QCD.

description: Pastoralists-farmers’ conflicts in Nigeria have grown, spread and intensified over the past decade and today pose a threat to national survival. Thus, this study measured food security status, assessed the effect of pastoralist- crop farmers’ conflict on food security and described the coping strategies employed by the respondents to reduce the effects of the conflict. Proportional sampling method was used to select a sample of 200 farming households. The analytical tools include descriptive statistics, logistic regression and food security index. The study indicated that 54.5% and 45.5% of the respondents were food secure and food insecure, respectively. Furthermore, pastoralist-crop farmers’ conflict, household size, sex, farm distance and access to co-operatives were the significant factors driving to food security in the area. Moreover, farmers generally used a combination of strategies to manage conflict. The ‘use of job experience, hard-working, early cropping, appease other party and seeking for help from relatives, village leaders and governments were some of the effective coping strategies used by the respondents to reduce the effects of conflict. Consequently, ranching and use of Rural Grazing Area (RUGA) settlement be encouraged by the government to reduce the effect of the conflict. Policies and strategies aimed at reducing the household size and enhancing cooperative formation should be pursued

description: We investigate the dependence of black-hole accretion rate (BHAR) on host-galaxy star formation rate (SFR) and stellar mass ($M_*$) in the CANDELS/GOODS-South field in the redshift range of $0.5\leq z < 2.0$. Our sample consists of $\approx 18000$ galaxies, allowing us to probe galaxies with $0.1 \lesssim \mathrm{SFR} \lesssim 100\ M_\odot\ \mathrm{yr}^{-1}$ and/or $10^8 \lesssim M_* \lesssim 10^{11}\ M_{\odot}$. We use sample-mean BHAR to approximate long-term average BHAR. Our sample-mean BHARs are derived from the $Chandra$ Deep Field-South 7 Ms observations, while the SFRs and $M_*$ have been estimated by the CANDELS team through SED fitting. The average BHAR is correlated positively with both SFR and $M_*$, and the BHAR-SFR and BHAR-$M_*$ relations can both be described acceptably by linear models with a slope of unity. However, BHAR appears to be correlated more strongly with $M_*$ than SFR. This result indicates that $M_*$ is the primary host-galaxy property related to black-hole growth, and the apparent BHAR-SFR relation is largely a secondary effect due to the star-forming main sequence. Among our sources, massive galaxies ($M_* \gtrsim 10^{10} M_{\odot}$) have significantly higher BHAR/SFR ratios than less-massive galaxies, indicating the former have higher black-hole fueling efficiency and/or higher SMBH occupation fraction than the latter. Our results can naturally explain the observed proportionality between $M_{\rm BH}$ and $M_*$ for local giant ellipticals, and suggest their $M_{\rm BH}/M_*$ is higher than that of local star-forming galaxies. Among local star-forming galaxies, massive systems might have higher $M_{\rm BH}/M_*$ compared to dwarfs.

DSMC investigation of rarefied gas flow through diverging micro- and nanochannels

description: Direct simulation Monte Carlo (DSMC) method with simplified Bernoulli-trials (SBT) collision scheme has been used to study the rarefied pressure-driven nitrogen flow through diverging microchannels. The fluid behaviours flowing between two plates with different divergence angles ranging between 0$^{\circ}$ to 17$^{\circ}$ are described at different pressure ratios (1.5${\le}{\prod}{\le}$2.5) and Knudsen numbers (0.03${\le}$Kn${\le}$12.7). The primary flow field properties, including pressure, velocity, and temperature, are presented for divergent microchannels and are compared with those of a microchannel with a uniform cross-section. The variations of the flow field properties in divergent microchannels, which are influenced by the area change, the channel pressure ratio and the rarefication are discussed. The results show no flow separation in divergent microchannels for all the range of simulation parameters studied in the present work. It has been found that a divergent channel can carry higher amounts of mass in comparison with an equivalent straight channel geometry. A correlation between the mass flow rate through microchannels, the divergence angle, the pressure ratio, and the Knudsen number has been suggested. The present numerical findings prove the occurrence of Knudsen minimum phenomenon in micro- and Nano- channels with non-uniform cross-sections.

description: We investigate the presence of COMs in strongly UV-irradiated interstellar molecular gas. We have carried out a complete millimetre line survey using the IRAM30m telescope towards the edge of the Orion Bar photodissociation region (PDR), close to the H2 dissociation front, a position irradiated by a very intense far-UV (FUV) radiation field. These observations have been complemented with 8.5 arcsec resolution maps of the H2CO 5(1,5)-4(1,4) and C18O 3-2 emission at 0.9 mm. Despite being a harsh environment, we detect more than 250 lines from COMs and related precursors: H2CO, CH3OH, HCO, H2CCO, CH3CHO, H2CS, HCOOH, CH3CN, CH2NH, HNCO, H13-2CO, and HC3N (in decreasing order of abundance). For each species, the large number of detected lines allowed us to accurately constrain their rotational temperatures (Trot) and column densities (N). Owing to subthermal excitation and intricate spectroscopy of some COMs (symmetric- and asymmetric-top molecules such as CH3CN and H2CO, respectively), a correct determination of N and Trot requires building rotational population diagrams of their rotational ladders separately. We also provide accurate upper limit abundances for chemically related molecules that might have been expected, but are not conclusively detected at the edge of the PDR (HDCO, CH3O, CH3NC, CH3CCH, CH3OCH3, HCOOCH3, CH3CH2OH, CH3CH2CN, and CH2CHCN). A non-LTE LVG excitation analysis for molecules with known collisional rate coefficients, suggests that some COMs arise from different PDR layers but we cannot resolve them spatially. In particular, H2CO and CH3CN survive in the extended gas directly exposed to the strong FUV flux (Tk = 150-250 K and Td > 60 K), whereas CH3OH only arises from denser and cooler gas clumps in the more shielded PDR interior (Tk = 40-50 K). We find a HCO/H2CO/CH3OH = 1/5/3 abundance ratio. These ratios are different from those inferred in hot cores and shocks.

Reviving of Nigerian Rubber Industry through Export Potential Enhancement

description: The need to shore-up the continuous widening gap of the nation’s revenue owing to dwindling oil price has forced the Nigerian government to start looking towards non-oil products especially agricultural cash crops for foreign exchange earnings. Since agriculture was the mainstay of the Nigerian economy before the oil boom, the need to look into this sub-sector to keep the nation’s economy afloat becomes a sine-qua-non. It is in view of this thrust that the present research intends to chart a course towards examining the potential of reviving the rubber sub-sector, being an important cash crop with high economic demand in the world. The research used dated data that spanned from 1961 to 2017 and it covered production, area, yield and producer’s price (rubber). The data were sourced from the FAO database and analyzed using both descriptive and inferential statistics. Empirical evidence showed that the incremental change in the country’s rubber production in Nigeria was majorly driven by area expansion which could be used for other purposes. Therefore, the future of the sub-sector is not promising to owe the fact that the slight gentle rise in the forecasted production trend will be driven by a gentle incremental rise in the annual production area while the level of productivity decreased year to year. The decrease in the forecasted annual yield levels is as a result of non-productive income and not technology. This is because the farmers are at the mercy of the Licensed Buyers (LBs) who exploit the producers through adopting collusive effects rather than to allow the market forces to determine the prevailing market price. The Licensed Buyers also served as the major link to the exporting markets. Therefore, the study recommends the establishment of farmer`s co-operative organizations so as to venture into export marketing and to increase their bargaining power. Moreover, both governmental and nongovernmental organizations should facilitate viable export market linkages to these farmers’ co-operatives. Furthermore, viable governmental policies should be framed to make the rubber market competitive for farmers, middlemen, local and international industrial consumers in the value chain.
