The birds were given.feed an. water ad libitum.with a 23-hour light regim.n.for a period of 4 weeks. Then. the experim.n.al birds were evaluated for body weight gain. feed con.um.tion. an. feed con.ersion.in.order to determ.n. their optim.m.requirem.n. for dietary Lysin. an. Glutam.n.. Based on.the fin.in.s of this study, the highest perform.n.e was observed in.birds fed the diet supplem.n.ed with 1.42 lysin. an. 1% glutam.n., but the highest im.rovem.n. in.feed con.ersion.was observed in.diet con.ain.1.14 an. 1.42 with 1% an. 3% glutam.n., respectively. Birds fed 1.42 lysin. an. 1% glutam.n. had the highest total body weight gain.an. feed con.um.tion.

Recen.ly, m.st wave en.rgy research has targeted sea areas with high power den.ity un.er extrem. wave con.ition. for deploym.n.. This tren. often.leads to higher en.rgy costs for wave power plan.s.

The respon.es evaluated were the pulp yield, cellulose con.en., an. the degree of delign.fication. Various regression.m.dels were used to evaluate the effects of varyin. the pulpin. con.ition.. The optim.m.con.ition. attain.d were;n.OH charge of 14.63%, 0.1% an.hraquin.n., an. a pulpin. period of 154 m.n.tes, correspon.in. to 20.68% pulp yield, 80.56% cellulose con.en., an. 70.34% lign.n.rem.val.
