Different Magnitude-Epicentral Intensity Relations and Estimation of Maximum Ground Acceleration

For an earthquake of magnitude 7.0 or larger, different published relations between magnitude, M, and epicentral intensity, I0, yield I0 values which may differ from each other by as much as one intensity unit or more. This implies an uncertainty of a factor of about 2 in the estimation of maximum ground acceleration. New empirical relations between M and I0 are derived using the revised estimates of I0 for several earthquakes. Suitability of some of the commonly used M - I0 relations for the estimation of maximum ground acceleration is examined by deriving acceleration-distance curves for different magnitude earthquakes (viz., 5.6, 6.6 and 7.6), using an intensity attenuation relation for the San Andreas attenuation province. The intensity to acceleration conversion is accomplished by using the relation published by Trifunac and Brady (1975). These acceleration-distance curves are compared with several recent acceleration attenuation studies for the western United States. It is found that the use of M - I0 relation derived in this study yields satisfactory acceleration-distance curves for different magnitudes

Wideband slotted patch antennas using EBG structures

Copyright @ 2010 IEEEA slotted microstrip patch antenna is designed with Electromagnetic Band gap (EBG) structures. The performance parameters of the presented antenna are then compared with the conventional patch antenna. It is realized that there is a significant increase of bandwidth and better suppression of harmonics than the normal patch antenna. This antenna is thus operating in the frequency band 5 - 6 GHz which is one of the most usable bandwidth regions for wireless applications such as WiMAX, WiFi outdoor, WLAN, Hiperlan/2 and many more. The proposed antenna achieves a gain between 4 to 6 dBi built in FR-4 material

Reducing Memory Cost of Exact Diagonalization using Singular Value Decomposition

We present a modified Lanczos algorithm to diagonalize lattice Hamiltonians with dramatically reduced memory requirements, {\em without restricting to variational ansatzes}. The lattice of size $N$ is partitioned into two subclusters. At each iteration the Lanczos vector is projected into two sets of $n_{{\rm svd}}$ smaller subcluster vectors using singular value decomposition. For low entanglement entropy $S_{ee}$, (satisfied by short range Hamiltonians), the truncation error is expected to vanish as $\exp(-n_{{\rm svd}}^{1/S_{ee}})$. Convergence is tested for the Heisenberg model on Kagom\'e clusters of 24, 30 and 36 sites, with no lattice symmetries exploited, using less than 15GB of dynamical memory. Generalization of the Lanczos-SVD algorithm to multiple partitioning is discussed, and comparisons to other techniques are given.Comment: 7 pages, 8 figure

Occurrence and incidence of foot rot disease on fenugreek caused by Fusarium moniliforme in Rohilkhand region of Uttar Pradesh, India

Pathological studies were carried out in Rohilkhand region during the crop season 2013-14 to assess the pathogenic disease incidence of foot rot of fenugreek (Trigonella foenum-graecum Linn.) caused by Fusarium moniliforme. A total of 75 fields were surveyed during the crop period at monthly interval during germination, vegetative, flowering and fruiting stages in five different localities of Rohilkhand region. The foot-rot disease of fenugreek was found in all fields (Bareilly, Baheri, Pilibhit, Budaun and Meerganj) selected for the study. Monthly occurrence of disease incidence of foot rot ranged from 44-58%. Maximum disease incidence was recorded in the month of Oct. (58%) followed by September (57%) and November (56%). January exhibited the lowest incidence (45%) of pathogenic disease. However, foot rot symptoms developed at early stage of plant growth and persisted up to the end of the crop

Studi Angkutan Sedimen Sudetan Pelangwot-Sedayu Lawas Sungai Bengawan Solo

Sungai Bengawan Solo merupakan salah satu sungai terpanjang di Indonesia yang mengalir mulai dari area hulu di Kabupaten Wonogiri dan Ponorogo hingga ke area hilir di Kabupaten Gresik. Perubahan fungsi lahan di area hulu dan peningkatan debit yang melalui Sungai Bengawan Solo membuat banjir terjadi di area hilir sungai yakni di Kabupaten Bojonegoro dan Kabupaten Gresik. Sudetan Pelangwot sepanjang 13 km merupakan saluran yang dibuat untuk mengurangi debit banjir yang terjadi dengan mengalirkannya ke laut Jawa. Namun dikarenakan pendangkalan yang terjadi akibat sedimentasi, kapasitas Sudetan Pelangwot dalam mengalirkan debit menurun. Tugas akhir ini bertujuan untuk menganalisa sedimentasi yang terjadi pada sudetan Pelangwot dengan menggunakan program bantu HEC-RAS 4.1.0 Konsep yang digunakan dalam pengerjaan tugas akhir ini adalah dengan memodelkan Sudetan Pelangwot menggunakan program HEC-RAS 4.1.0 kemudian melakukan simulasi aliran sudetan untuk mengetahui sedimentasi yang terjadi. Dari hasil simulasi yang dilakukan dengan menggunakan program HEC-RAS 4.1.0 diketahui perkiraan volume sedimentasi yang terjadi di sudetan selama musim penghujan dari tanggal 1 Desember 2010 hingga 21 Mei 2011 adalah sebesar 325.030,23 m3. Agradasi terjadi di sebagian besar penampang sudetan sedangkan degradasi hanya terjadi di beberapa titik. Kantong sedimen dapat dibuat sebagai upaya pengendalian sedimen pada dasar saluran sudetan di tiga titik yang berbeda dengan kapasitas total 175.875 m3.Pemeliharaan kantong sedimen dilakukan setiap 3 bulan sekali dengan melakukan pengerukan pada kantong sedimen

Rural finance policies for food security of the poor

The objective of IFPRI's multicountry research program on rural financial policies for food security of the poor is to identify policies and institutional arrangements that help the poor integrate themselves into sustainable savings and credit systems such that they have an increased capacity to invest, bear risk, and smooth consumption. The focus of the research on policy and program design and their effects on household investment and consumption requires field data collection at the institutional and household level. This paper presents the underlying conceptual framework and various methodological approaches that have been reviewed and tested by the team at IFPRI and at collaborating institutions. Methodologies are presented for analysis at the institutional level, mainly focusing on the determinants of the formation of financial institutions and the analysis of effects of program design on institutional conduct and performance, and at the household level, thereby addressing determinants of access to and participation in financial markets and related effects on household welfare.Food security Developing countries. ,Financial institutions. ,Households Economic aspects. ,

Potensi Susu Kedelai Asam (Soygurt) Kaya Bioaktif Peptida Sebagai Antimikroba

The research objective was to get the starter type and the fermentation time to produce soygurt that have a high peptide bioactive that functions as an antimicrobial. The study was conducted in a complete randomized block design with two replicates. The first factor is the starter types, which consists of 3 levels, 2 market starter (cimory and king yogurt) and 1 mixed starter. The second factor is the fermentation times, which consists of 3 levels, 9 hours, 12 hours, and 15 hours. The data obtained were analyzed by analysis of variance to get various error estimators and tests of significance by Duncan\u27s test further to determine whether there is a difference between treatments. Two market starter (cimory and king yogurt) and 1 mixed starter did not produce peptide bioactive compounds . It is suspected microbes contained in the market starter cimory (S.thermophilus and L.delbrueckii ssp . Bulgaricus ), the market starter king yogurt (L.bulgaricus) and mixed starter (S.thermophilus and L.bulgaricus) did not produce peptide bioactive compounds. The inhibition effect of the test bacteria (E. coli and S. aureus) occurs due to the production of lactic acid and hydrogen peroxide during the fermentation process . The greatest inhibition shown by soygurt of the market starter cimory with a reduced number of cells in both types of test bacteria (E. coli and S. aureus) at 6 and 5 log cycles . Mixed starter has the lowest pH and the highest total acid than the marker starter cimory and king yoghurt. The starter types and the fermentation times were no significant effect on total dissolved solids of soygurt. The levels protein of soygurt, respectively 1.38 %, 1.48 %, and 1.68 (cimory, king yogurt, and mixed starter), while the fat content of soygurt 1.04%, 1.28 %, and 1.58% (cimory, mixed starter, king yoghurt
