Effective action of magnetic monopole in three-dimensional electrodynamics with massless matter and gauge theories of superconductivity

We compute one-loop effective action of magnetic monopole in three-dimensional electrodynamics of massless bosons and fermions and find that it contains an infrared logarithm. So, when the number of massless matter species is sufficiently large, monopoles are suppressed and in the weak coupling limit charged particles are unconfined. This result provides some support to gauge theories of high-temperature superconductors. It also provides a mechanism by which interlayer tunneling of excitations with one unit of the ordinary electric charge can be suppressed while that of a doubly charged object is allowed.Comment: 8 pages, LATEX, UCLA/93/TEP/41 (the last sentence of the paragraph concerning applications at the end of the paper has been deleted; mailing problems have been corrected

Linear Response for Granular Fluids

The linear response of an isolated, homogeneous granular fluid to small spatial perturbations is studied by methods of non-equilibrium statistical mechanics. The long wavelength linear hydrodynamic equations are obtained, with formally exact expressions for the susceptibilities and transport coefficients. The latter are given in equivalent Einstein-Helfand and Green-Kubo forms. The context of these results and their contrast with corresponding results for normal fluids are discussed.Comment: Submitted to PR

Growth of Population Density -2020-2021 Thanjavur Districts, Tamilnadu. To Using the Geographical Information System

AbstractIn this study I have used a population project model to estimate the population growth for Thanjavur district, Tamil nadu. Until the years 2021 and to calculate the current and future needs elements in urban planning of the Thanjavur district. For urbanizations, I have employed GIS arc Info to digitize the maps and GIS-arc view to process the data combining with other analytical measurements to display the result.

Sister R.S. Subbalakshmi's Role in the Renaissance of Hindu Community : A special study based on the Educational standard of Tamil Nadu women in 19th and 20th Centuries

The rise and fall of Hindu Community in India is a historical phenomenon. There are various personalities who dedicated themselves to the renaissance of them, regardless of victory or defeat in their efforts. Though the Hindu community seemed to advance in a number of fields in Tamil Nadu especially during the 19th and 20th centuries despite various forms of oppression and destruction. Under- age marriage was among many other factors that resulted in the backwardness of the society. In such a backdrop, the role played by a number of female personalities was immensely commendable for the reawakening activities. R.S. Subbalakshmi, Dr. Muthulatchumi Rettiyar, Sarojini Naidu, etc are a few to be added to the list of the reformers who tirelessly put all their efforts for the reawakening of Tamil women. Most notably, R.S. Subbalakshmi successfully carried out her mission towards the educational renaissance of widows. Her service has to be specially noted for her careful forward without getting caught into the clutches of the British rulers, instead obtaining their cooperation and support. She carried out her educational activities adopting the modern educational reforms of the British, while preserving the national heritage of India. The Institutions such as Saratha Ashram, Sri Saratha United Women Society, Sri Saratha Vidyalayam, which played a major role in the educational renaissance of the South Indian women, were established by her. She had to encounter untold hardships to operate those Institutions which brought a turning point in a number of educated women. Since she undertook her activities irrespective of societal differences, the rulers, philanthropists and well wishers offered their fullest support and assistance. Her activities were pioneer for the creation of other social organizations and Institutions. She is to be regarded as a forward thinker who always thought of the well being of not only the women of Tamil Nadu but of the whole South India

Two Phases for Compact U(1) Pure Gauge Theory in Three Dimensions

We show that if actions more general than the usual simple plaquette action ($\sim F_{\mu\nu}^2$) are considered, then compact $U(1)$ {\sl pure} gauge theory in three Euclidean dimensions can have two phases. Both phases are confining phases, however in one phase the monopole condensate spontaneously `magnetizes'. For a certain range of parameters the phase transition is continuous, allowing the definition of a strong coupling continuum limit. We note that these observations have relevance to the `fictitious' gauge field theories of strongly correlated electron systems, such as those describing high-$T_c$ superconductors.Comment: 10 pages, Plain TeX, uses harvma

Fiscal decentralization, ideology, and the size of the public sector

No consensus has yet emerged on whether fiscal decentralization facilitates or impedes the growth of the public sector. One explanation for this ambiguity in the literature is that the effect of fiscal decentralization on public sector size depends on the government’s ideology. This paper therefore develops a simple model to study theoretically how interactions between fiscal decentralization and the ideology of the government may influence the size of the public sector. Thereafter, the implications of the model are tested empirically with panel data from 18 OECD countries over the 1980-2000 period

Determination of Dark Energy by the Einstein Telescope: Comparing with CMB, BAO and SNIa Observations

A design study is currently in progress for a third generation gravitational-wave (GW) detector called Einstein Telescope (ET). An important kind of source for ET will be the inspiral and merger of binary neutron stars (BNS) up to $z \sim 2$. If BNS mergers are the progenitors of short-hard $\gamma$-ray bursts, then some fraction of them will be seen both electromagnetically and through GW, so that the luminosity distance and the redshift of the source can be determined separately. An important property of these `standard sirens' is that they are \emph{self-calibrating}: the luminosity distance can be inferred directly from the GW signal, with no need for a cosmic distance ladder. Thus, standard sirens will provide a powerful independent check of the $\Lambda$CDM model. In previous work, estimates were made of how well ET would be able to measure a subset of the cosmological parameters (such as the dark energy parameter $w_0$) it will have access to, assuming that the others had been determined to great accuracy by alternative means. Here we perform a more careful analysis by explicitly using the potential Planck CMB data as prior information for these other parameters. We find that ET will be able to constrain $w_0$ and $w_a$ with accuracies $\Delta w_0 = 0.099$ and $\Delta w_a = 0.302$, respectively. These results are compared with projected accuracies for the JDEM Baryon Acoustic Oscillations project and the SNAP Type Ia supernovae observations.Comment: 28 pages, 5 figures, 5 tables; Published Versio

Phytotoxic Effect to Cockscomb (Celosia cristata L.) with Response of Chlorpyrifos Treatments

The present work was conducted to evaluate the phytotoxic of chlorpyrifos on cockscomb (Celosia cristata L.) plant.  The seeds was exposed different dosage (control, 0.5, 1, 2 and 2.5%) of chlorpyrifos. On the 7th day seed germination percentage were determined, seedling morphological such as shoot length, root length, biomass and photosynthetic pigments like chlorophyll ‘a’ and chlorophyll ‘b’ were examined on 30, 60 and 90 days after treatments. The germination percentage negatively affect with increasing chlorpyrifos level. The morphological and photosynthetic pigments were increases at optimum level (0.5%). Moreover, above the optimum concentration all investigated parameters was decreased with increasing chlorpyrifos level. The obtained results suggest that usage of this insecticide optimum dosage helpful for good agricultural practices
