The optimum levels of Lysin. an. Glutamin. n.eded for growth performan.e an. main.en.n.e of the chicken.broilers were evaluated in.a ran.omized 3 × 4 factorial arran.emen. of dietary treatmen.s. The battery cages measured 99 × 66 × 25 cm that can.be sufficien. for 5 birds. Day old Chicken.broilers totalin. 180 were assign.d to dietary treatmen.s comprisin. of 3 con.en.ration. of Lysin. (0.85, 1.14, an. 1.42) each in.combin.tion.with 4 con.en.ration. of Glutamin. (0, 1, 2, an. 3). Each dietary treatmen. was replicated 3 times an. each replication.had 5 birds. The birds were given.feed an. water ad libitum with a 23-hour light regimen.for a period of 4 weeks. Then. the experimen.al birds were evaluated for body weight gain. feed con.umption. an. feed con.ersion.in.order to determin. their optimum requiremen. for dietary Lysin. an. Glutamin.. Based on.the fin.in.s of this study, the highest performan.e was observed in.birds fed the diet supplemen.ed with 1.42 lysin. an. 1% glutamin., but the highest improvemen. in.feed con.ersion.was observed in.diet con.ain.1.14 an. 1.42 with 1% an. 3% glutamin., respectively. Birds fed 1.42 lysin. an. 1% glutamin. had the highest total body weight gain.an. feed con.umption. The lysin. requiremen.s in.the diet for Chicken.are between.1.14 an. 1.42 with glutamin. level of 1%.

Perin.al trauma followin. childbirth affects over two-thirds of women.in.low an. medium-in.ome coun.ries (LMICs) birthin. in.health facilities. Although it is an.un.avourable outcome with the poten.ial to affect man. aspects of a woman.s well-bein. in.both the immediate an. lon.-term, it is still a n.glected phen.men.n.of women.s health, particularly in.sub-Saharan.African.coun.ries like Zambia. This study sought to un.erstan. the impact of birth perin.al trauma on.postn.tal women.at n.ola Teachin. Hospital (n.H). This study employed a cross-section.l qualitative design.usin. a descriptive phen.men.logical approach. Fifteen.women.who had birthed at n.H an. sustain.d birth perin.al trauma were purposively sampled as study participan.s. Data were collected through face-to-face in.erviews aided by an.in.erview guide. Four themes, n.mely, perin.al pain. substan.ard perin.al woun. man.gemen., fear of future reproductive health outcomes an. diversion.from reality, emerged from the study. Most women.experien.in. childbirth perin.al trauma do n.t receive adequate care to man.ge their con.ition.effectively. Therefore, midwives should utilise their profession.l kn.wledge an. skills when.providin. postn.tal care because morbidity affects women. Thus, it has the poten.ial to n.gatively affect mother-in.an. bon.in.. The study con.luded that birth perin.al trauma is a distressin. phen.men.n.of childbirth;hen.e, skillful repair, pain.man.gemen. an. sexual coun.ellin. can.greatly reduce its n.gative impacts.

This research en.ails the study of heat an. mass tran.fer of n.n.fluid flow in.a fluidized bed dryer used in.tea dryin. processes in.presen.e of in.uced magn.tic field. A mathematical model describin. the fluid flow in.a Fluidized bed dryer was developed usin. the n.n.in.ar partial differen.ial equation.. Due to their n.n.lin.arity, the equation. were solved n.merically by use of the fin.te differen.e method. The effects of physical flow parameters on.velocity, temperature, con.en.ration.an. magn.tic in.uction.profiles were studied an. results were presen.ed graphically. From the mathematical an.lysis, it was deduced that addition.of silver n.n.particles in.o the fluid flow en.an.ed velocity an. temperature profiles. This led to improved heat tran.fer in.the fluidized bed dryer, hen.e amplifyin. the tea dryin. process. Furthermore, it was n.ted that in.uced magn.tic field ten.s to decrease the fluid velocity, which results in.un.form distribution.of heat leadin. to efficien. heat tran.fer between.the tea particles an. the fluid, thus improvin. the dryin. process. The research fin.in.s provide in.ormation.to in.ustries on.ways to optimize thermal performan.e of fluidized bed dryers.

In.this article, a n.vel scalarization.techn.que, called the improved objective-con.train. approach, is in.roduced to fin. efficien. solution. of a given.multiobjective programmin. problem. The presen.ed scalarized problem exten.s the objective-con.train. problem. It is demon.trated that how addin. variables to the scalarized problem, can.lead to fin. con.ition. for (weakly, properly) Pareto optimal solution.. Applyin. the obtain.d n.cessary an. sufficien. con.ition., two algorithms for gen.ratin. the Pareto fron. approximation.of bi-objective an. three-objective programmin. problems are design.d. These algorithms are easy to implemen. an. can.achieve an.even.approximation.of (weakly, properly) Pareto optimal solution.. These algorithms can.be gen.ralized for optimization.problems with more than.three criterion.fun.tion., too. The effectiven.ss an. capability of the algorithms are demon.trated in.test problems.
