Let f, g: X → Y be maps from a compact in.ra-n.lman.fold X to a compact n.lman.fold Y with dim X ≥ dim Y. In.this n.te, we show that a certain.Wecken.type property holds, i.e., if the n.elsen.n.mber n.f, g) van.shes then.f an. g are deformable to be coin.iden.e free. We also show that if X is a con.ected fin.te complex X an. the Reidemeister coin.iden.e n.mber R(f, g) = ∞ then.f ～ f' so that C(f', g) = {x ∈ X | f'(x) = g(x)} is empty.

In.Tan.an.a, maize is the main.complemen.ary food for in.an.s an. primary school children. Dietary exposure to mycotoxin. through complemen.ary foods by Tan.an.an.in.an.s is of con.ern. The maize storage an. con.umption.practices of farmers in.Han.en. District, Tan.an.a an. their implication. for mycotoxin.con.amin.tion.of maize flour were in.estigated. A con.en.en. sample of 60 farmers in.Seza Kofi an. Kwabojo villages in.Mgambo an. n.olwa wards were surveyed. The majority of farmers (95%) stored their maize in.the house usin. the roofin. an. sack methods. Most farmers (67%) did n.t visually or mechan.cally sort defective maize kern.ls before storage. In.both villages, the most importan. storage problems reported by the farmers were roden.s an. in.ects. Forty two percen. of the farmers surveyed in.icated that they con.umed dehulled maize, while 35 an. 12% con.umed n.n.dehulled an. mixed (dehulled an. n.n.dehulled), respectively. The prepon.eran.e of storage practices described was un.avorable to mycotoxin.reduction.in.stored maize. It is therefore recommen.ed that appropriate, area-specific farmer train.n. regardin. recommen.ed storage practices in.ludin. storage methods, effective man.gemen. of storage pests an. healthy maize preparation.an. con.umption.practices be con.ucted. Addition.lly, further research on.maize storage an. con.umption.practices for Tan.an.a is n.eded.
