Perbandingan Perhitungan Trafik Jam Sibuk CDMA 2000 1x Pada BTS Inner City Dan BTS Outer City Dengan Mempergunakan Metode ADPH, TCBH, FDMH Dan FDMP
Cellular communication system is a wireless communication system where the subscriber can move within a wide network coverage. Code Division Multiple Access (CDMA) is a multiuser access technology that is each user uses a unique code contained in the access channel in the system. Calculation and determination of peak hours can be done by several methods such as: Average Daily Peak Hour (ADPH), Time Consistent Busy Hour (TCBH), Fixed Daily Measurement Hour (FDMH), Fixed Daily Measurement Period (FDMP). The effectiveness of the channel should be determined by occupancy both at inner city territory and outer city territory location. Using design Erlang (Erl) for supply channel at Base Transceiver Station (BTS) that provided, BTS has a design Erlang of 369,83 Erl at inner city and it has a design Erlang of 241,8 Erl at outer city. Peak hour on the inner city occurred at 12:00 to 15:00, whereas the outer city of peak hour occurred at 18:00 to 21:00. Effectiveness value that determined by operator are : <20% = low occupancy (not effective), 21% to 69% = normal occupancy (effective), and > 70% = high occupancy (very effective). In this case occupancy values obtained in each method is between 21% to 69% which means effectiv

A Novel Pathogenesis-Related Class 10 Protein <i>Gly m 4l,</i> Increases Resistance upon <i>Phytophthora sojae</i> Infection in Soybean (<i>Glycine max</i> [L.] Merr.)
<div><p>Phytophthora root and stem rot of soybean, caused by <i>Phytophthora sojae</i> (<i>P</i>. <i>sojae</i>), is a destructive disease in many soybean planting regions worldwide. In a previous study, an expressed sequence tag (EST) homolog of the major allergen <i>Pru ar 1</i> in apricot (<i>Prunus armeniaca</i>) was identified up-regulated in the highly resistant soybean ‘Suinong 10’ infected with <i>P</i>. <i>sojae</i>. Here, the full length of the EST was isolated using rapid amplification of cDNA ends (RACE). It showed the highest homolgy of 53.46% with <i>Gly m 4</i> after comparison with the eight soybean allergen families reported and was named <i>Gly m 4-like</i> (<i>Gly m 4l</i>, GenBank accession no. HQ913577.1). The cDNA full length of <i>Gly m 4l</i> was 707 bp containing a 474 bp open reading frame encoding a polypeptide of 157 amino acids. Sequence analysis suggests that <i>Gly m 4l</i> contains a conserved ‘P-loop’ (phosphate-binding loop) motif at residues 47–55 aa and a Bet v 1 domain at residues 87–120 aa. The transcript abundance of <i>Gly m 4l</i> was significantly induced by <i>P</i>. <i>sojae</i>, salicylic acid (SA), NaCl, and also responded to methyl jasmonic acid (MeJA) and ethylene (ET). The recombinant <i>Gly m 4l</i> protein showed RNase activity and displayed directly antimicrobial activity that inhibited hyphal growth and reduced zoospore release in <i>P</i>. <i>sojae</i>. Further analyses showed that the RNase activity of the recombinant protein to degrading tRNA was significantly affected in the presence of zeatin. Over-expression of <i>Gly m 4l</i> in susceptible ‘Dongnong 50’ soybean showed enhanced resistance to <i>P</i>. <i>sojae</i>. These results indicated that <i>Gly m 4l</i> protein played an important role in the defense of soybean against <i>P</i>. <i>sojae</i> infection.</p></div
