Instanton representation of Plebanski gravity. Application to gravitons about DeSitter spacetime

Using the instanton representation method, we re-construct graviton solutions about DeSitter spacetime. We have used this example as a testing arena to expose the internal structure of the method and to establish that it works for known solutions. This paper is a precursor for its application to the construction of new General Relativity solutions in future work.Comment: 16 pages. Accepted by the International Journal of Modern Physics

Finite states in four dimensional quantized gravity

This is the first in a series of papers outlining an algorithm to explicitly construct finite quantum states of the full theory of gravity in Ashtekar variables. The algorithm is based upon extending some properties of a special state, the Kodama state for pure gravity with cosmological term, to matter-coupled models. We then illustrate a presciption for nonperturbatively constructing the generalized Kodama states, in preparation for subsequent works in this series. We also introduce the concept of the semiclassical-quantum correspondence (SQC). We express the quantum constraints of the full theory as a system of equations to be solved for the constituents of the `phase' of the wavefunction. Additionally, we provide a variety of representations of the generalized Kodama states including a generalization of the topological instanton term to include matter fields, for which we present arguments for the field-theoretical analogue of cohomology on infinite dimensional spaces. We demonstrate that the Dirac, reduced phase space and geometric quantization procedures are all equivalent for these generalized Kodama states as a natural consequence of the SQC. We relegate the method of the solution to the constraints and other associated ramifications of the generalized Kodama states to separate works.Comment: 42 pages: Accepted for publication by Class.

Finite states in four dimensional quantum gravity. The isotropic minisuperspace Asktekar--Klein--Gordon model

In this paper we construct the generalized Kodama state for the case of a Klein--Gordon scalar field coupled to Ashtekar variables in isotropic minisuperspace by a new method. The criterion for finiteness of the state stems from a minisuperspace reduction of the quantized full theory, rather than the conventional techniques of reduction prior to quantization. We then provide a possible route to the reproduction of a semiclassical limit via these states. This is the result of a new principle of the semiclassical-quantum correspondence (SQC), introduced in the first paper in this series. Lastly, we examine the solution to the minisuperspace case at the semiclassical level for an isotropic CDJ matrix neglecting any quantum corrections and examine some of the implications in relation to results from previous authors on semiclassical orbits of spacetime, including inflation. It is suggested that the application of nonperturbative quantum gravity, by way of the SQC, might potentially lead to some predictions testable below the Planck scale.Comment: 26 pages.

Similarities of gauge and gravity amplitudes

We review recent progress in computations of amplitudes in gauge theory and gravity. We compare the perturbative expansion of amplitudes in N=4 super Yang-Mills and N=8 supergravity and discuss surprising similarities.Comment: Talk presented by Harald Ita at "Continuous Advances in QCD 2006", 7 page

Perturbative Gravity and Twistor Space

The recent progress in computing gauge theory amplitudes can be extended, in many cases, to theories incorporating gravity. This has improved our understanding of the perturbative expansion of N=8 supergravity supporting the ``no-triangle hypothesis'' that N=8 one-loop amplitudes may be expressed in terms of scalar box integral functions.Comment: Talk presented by N.

Hubungan Gangguan Masa Menopause dengan Tingkat Kecemasan pada Ibu Menopause di Desa Dawuhan Kecamatan Purwoasri Kabupaten Kediri

Menopause adalah suatu masa berakhirnya reproduksi wanita yang disebabkan berkurangnya hormon estrogen dan progesteron yang ditandai oleh berhentinya haid. Pada masa ini terjadi gangguan yang menimbulkan kecemasan dan berdampak memacu organ tubuh tidak stabil. Hal ini membuat wanita menopause merasa terganggu dalam menjalankan kegiatan sehari-hari. Penelitian ini bertujuan untuk menganalisa hubungan gangguan masa menopause dengan tingkat kecemasan pada ibu menopause. Penelitian dilaksanakan pada tanggal 22-26 Januari 2014 di Desa Dawuhan Kecamatan Purwoasri Kabupaten Kediri. Desain penelitian menggunakan desain studi korelasional dengan variabel independen gangguan masa menopause pada wanita, variabel dependen tingkat kecemasan wanita saat menopause, dengan populasi wanita menopause 105 jiwa, jumlah sampel adalah 84 responden wanita menopause usia 45-55 tahun diambil secara simple random sampling. Pengumpulan data menggunakan kuesioner berupa skala MRS untuk variabel independen dan TMAS untuk variabel dependen. Analisa data menggunakan uji Chi Square. Hasil analisis dengan Chi Square metode penghitungan manual X2 hitung > X2 tabel yaitu13,75 > 7,815 sehingga H1 terbukti yang artinya hubungan gangguan masa menopause dengan tingkat kecemasan pada ibu menopause di Desa Dawuhan, Kecamatan Purwoasri Kabupaten Kediri. Dalam penghitungan manual koefisien kontingensi didapatkan nilai 0,375 maka hubungan antara kedua variable rendah. Adanya Perubahan fisik wanita menopause menyebabkan kecemasan pada wanita menopause, tetapi ada faktor-faktor lain seperti sikap, gaya hidup, faktor kultur maupun psikologis serta status sosial ekonomi, yang mempengaruhi kecemasan wanita menopause

Sistem Informasi Raport Berbasis Web Di SMP N 4 Temanggung

The processed data with computer can be more convenient and practical compared with manual system. Data processing is done manually takes time and labor so much, that when dealing with complex data processing and large less efficient. Thus the use of a computer can be optimized. Therefore the "Web Based Information System Report Cards at SMP N 4 Temanggung" and as the title made in this thesis.Design of the information system of data processing was designed in order to process data effectively and efficiently in the process of inputting student data, teacher data, the value of data subjects as well as report cards, in addition to optimizing the use of existing computer in SMP N 4 Temanggung
