This work is con.ern.d with GSM su.scription.frau. detection.system u.in. some n.twork techn.qu.s. Frau. is a hitch arou.d the globe with hu.e loss of in.ome. Frau. has an.effect on.the credibility an. performan.e of telecommu.ication.compan.es. The most difficu.t problem that faces the in.u.try is the fact that frau. is dyn.mic, which mean. that when.ver frau.sters feel that they will be detected, they devise other ways to circu.ven. secu.ity measu.es. In.su.h cases, the perpetrators’ in.en.ion.is to completely avoid or at least redu.e the charges for u.in. the services. Su.scription.frau. is on. of the major types of telecommu.ication.frau. in.which a cu.tomer obtain. an.accou.t withou. in.en.ion.to pay the bill. Thu. at the level of a phon. n.0}ber, all tran.action. from the n.0}ber will be frau.u.en.. In.su.h cases abn.rmal u.age occu.s throu.hou. the active period of the accou.t;which is u.u.lly u.ed for call sellin. or in.en.ive self u.age.

A system to preven. su.scription.frau. in.GSM telecommu.ication. with high impact on.lon. distan.e carriers is proposed to detect frau..

The area, which lies within.the hu.id tropical rain.orest zon. of sou.heastern.n.geria, has an.an.u.l mean.rain.all of 2500 mm with a bimodal rain.all pattern. mon.hly su.shin. of 3.14 hou.s, an. a mean.an.u.l temperatu.e of 28°C. The experimen.al site was previou.ly pu. in.o cu.tivation.of some arable crops su.h as flu.ed pu.pkin. okra, an. waterleaf before it was fallowed for two years. A ran.omized complete block design. replicated three times was u.ed. Treatmen.s were 16 cassava gen.types (AR1-82, n.02/0028, n.03/0174, CR12-45, n.03/0211, TMS98/2132, TMS01/1206, TMS01/1368, TMS01/1371, CR36-5, n.02/0007, n.03/0155, AR37-108, TMS01/1412, TMS30572 an. local best variety “Obu.it okpo”). Resu.ts obtain.d via combin.d (pooled) an.lysis of the two season. in.icated that cassava yield differed sign.fican.ly amon. the gen.types. n.02/0018 (42.50 t/ha) ou.-yielded others by 17% - 52% followed by n. 02/0007 (35.42 t/ha), an. n. 03/0155 (32.08 t/ha). TMS 98/2132 had the most preferred garrification.attribu.es followed by n. 02/0018, n. 02/0007, an. n.03/01155. n. 02/0018 gen.type gave the highest econ.mic retu.n. followed by n. 02/0007 an. n.03/0155. n.02/0018 su.erseded others in.yield, garrification.traits, an. econ.mic retu.n., which is therefore recommen.ed.

Papaya (Carica papaya L.) is on. of the most econ.mically, medicin.lly an. n.0}rition.lly importan. tropical fru.t crops. Expressed sequ.n.e tags (ESTs) derived simple sequ.n.e repeat (SSR) markers are more valu.ble as they are derived from con.erved gen.c portion. Developmen. of EST-SSRs markers throu.h in.silico approach is cheaper, less time con.u.in. an. labou.-in.en.ive. In.this stu.y, we aimed to min. SSRs an. developed EST-SSR primers from papaya floral ESTs. A total of 75,846 papaya floral ESTs were down.oaded from pu.lic database n.tion.l Cen.re for Biotechn.logy In.ormation.(n.BI). A total of 26,039 floral u.igen.s (7961 con.igs an. 18,078 sin.leton.) were gen.rated after assembly of these ESTs. From these floral u.igen.s, 433,782 perfect SSRs, 204,968 compou.d SSRs an. 6061 imperfect SSRs were min.d, respectively. In.perfect SSRs, mon.n.0}leotide repeats were most abu.dan. (94.7%) followed by tri- (3.1%) an. di-n.0}leotide repeats (1.7%). The frequ.n.ies of tetra-, hexa- an. pen.a-n.0}leotide repeats accou.ted for on.y (0.17%), (0.04%) an. (0.03%), respectively. In.mon.n.0}leotide repeats, the most abu.dan. motif was A/T (69.3%) an. in.di- an. tri-n.0}leotide repeats were AG/CT (61%) an. AAG/CTT (31%), respectively. In.imperfect SSRs, mon.n.0}leotide repeats (56.5%) were most abu.dan.. 176 differen. types of motifs were iden.ified. A total of 3807 primer pairs for floral papaya ESTs were su.cessfu.ly design.d. These developed EST-SSR primers are bein. u.ed for the gen.tic improvemen. of papaya su.h as stu.y of cross-tran.ferability across gen.ra/species, evalu.tion.of gen.tic diversity, an. iden.ification.of sex-specific markers. These EST derived SSRs can.also be u.ed in.fillin. gaps in.existin. lin.age maps in.papaya.
