The pa.er a.a.yzes the influence of a.susceptible-infectious-susceptible （SIS） infectious disea.e a.fecting both fish a.d broiler species. The pa.er a.so considers a.joint SIS project of fish a.d broiler in which the growth ra.es of both species va.y with a.a.la.le nutrients a.d environmenta. ca.rying ca.a.ities of bioma.ses. The nutrients for both species a.e functions of the bioma.ses of the two species. The ha.vesting ra.es of fish a.d broiler depend linea.ly on common effort function. It is a.sumed tha. the disea.es a.e tra.s- mitted to the susceptible popula.ions by direct conta.t with the infected popula.ions. Using the medicine, some portion of the infected popula.ions a.e tra.smitted to the sus- ceptible popula.ions. The existence of stea.y sta.es a.d their sta.ility a.e investiga.ed a.a.ytica.ly.

This study a.ms to monitor the geomorphologica. cha.ges on the southern coa.ta. sa.k.a. due to the urba.iza.ion expa.sion. Geogra.hic informa.ion systems (GIS) a.d remote sensing (RS) techniques were used to study these cha.ges, determine the a.ea. of the coa.ta. sa.k.a. in the southern pa.t of k.wa.t, following the developments, a.d identifying la.d cover in the a.ea.a.d its coa.ta. strip including tourist resorts, sa.d dunes, a.d smooth sa.d sheets.
