Kwimveliso yanamhlanje, iivalvu, njengezixhobo zokulawula ulwelo olubalulekileyo, zidlala indima ebaluleke kakhulu. Nokubaiivalve butterfly, iivalve zesango, okanyekhangela iivalve, badlala indima ebalulekileyo kumashishini ahlukeneyo. Uyilo kunye nokuveliswa kwezi zivalo kubandakanya ubugcisa obugqwesileyo kunye nenkqubela phambili yobuchwepheshe. Emva kwayo yonke le nto, ootitshala kushishino lwevalvu bangumqolo welifa kunye nokusungula izinto ezintsha. Abangabo basasaza ulwazi kuphela, kodwa nabagadi bobugcisa.
Iivalve zebhabhathane, ezaziwa ngoyilo lwazo olukhaphukhaphu, umthamo ophezulu wokuhamba, kunye nokusebenza okugqwesileyo kokutywinwa, zisetyenziswa kakhulu kumashishini afana nepetroleum, ubunjineli bemichiza, kunye namandla ombane. Uyilo kunye nokuveliswa kwazo kufuna isiseko esiluqilima kwitekhnoloji kunye namava abanzi asebenzayo. Abahlohli boshishino lwevalvu badlulisela olu lwazi kubafundi ngomyalelo ocwangcisiweyo, ukukhulisa izizukulwana ezilandelelanayo zetalente ebalaseleyo yobugcisa. Abafundisi kuphela abafundi indlela yokuyila kunye nokwenza iivalve zebhabhathane, kodwa okona kubaluleke ngakumbi, babafundisa indlela yokuqonda iithiyori ezisisiseko ezifana nobuchwephesha bolwelo kunye nesayensi yezixhobo, okubenza bakwazi ukuzisebenzisa ngokuguquguqukayo kwiimeko zehlabathi lokwenyani.
Iivalvu zesangozizivalo eziqhelekileyo, ezisetyenziselwa ikakhulu ukuvala okanye ukudibanisa ulwelo kwimibhobho. Ngelixa ilula kulwakhiwo kwaye kulula ukuyisebenzisa, ukwenziwa kwazo kufuna ukukhethwa kwezinto eziphezulu kakhulu kunye nokuchaneka. Amagalelo ootitshala beshishini levalvu kulo mmandla akanakujongelwa phantsi. Ngokusebenzisa izandla-ngomyalelo, bavumela abafundi ukuba bathathe inxaxheba ngokobuqu kwinkqubo yokuvelisa ivalve yesango, ukuqonda ukubaluleka kwenyathelo ngalinye. Oku kuqokelelana kwamava asebenzisekayo akuphuculi nje izakhono zobuchule zabafundi kuphela kodwa kukwabeka isiseko esiluqilima sekamva labo lomsebenzi.
Khangela iivalvuzizixhobo ezibalulekileyo zokuthintela ulweloukubuyela emva kwaye zisetyenziswa ngokubanzi kunyango lwamanzi, ukufudumeza, kunye nokubonelela ngegesi. Uyilo kunye nokuveliswa kweevalvu zetshekhi kubandakanya ulwazi oluvela kwiinkalo ezininzi, kubandakanywa amandla olwelo kunye noyilo lomatshini. Ngokusebenzisa imiyalelo yezifundo ezahlukeneyo, abahlohli kushishino lwevalvu banceda abafundi baphuhlise isiseko solwazi olubanzi, okubenza bakwazi ukujongana nemingeni entsonkothileyo yobugcisa yamakhondo abo ekamva.
Kushishino lwevalvu, ootitshala abakuphela njeinika ngolwazi kodwa nabazuzi bomsebenzi wobugcisa. Basebenzisa amava kunye nobulumko babo ukulima izizukulwana zetalente yokuvelisa ivalvu, igalelo kuphuhliso loshishino lwemveliso yaseTshayina. Kungenxa kanye kanye ngenxa yokusebenza nzima kwaba tishala ukuba ishishini levalvu likwazi ukuqhubeka nokuvelisa izinto ezintsha kunye nokuqhubela phambili inkqubela kulo lonke ushishino lwemveliso.
Kwihlabathi lanamhlanje, ishishini lemveliso lijongene nemingeni kunye namathuba angazange abonwe ngaphambili. Njengenxalenye ebalulekileyo yoshishino lokwenziwa kwemveliso, ushishino lwevalvu kufuneka ngokuqhubekayo luphucule amandla alo obuchwepheshe kunye nobuchule bokusungula. Le mpumelelo ayinakwahlulwa kukusebenza nzima nokuzinikezela kootitshala bethu. Sifanele sihlawule kwaba badla ilifa lo msebenzi wobugcisa kwaye sibabulele ngegalelo labo kushishino lwevalvu kunye nehlabathi lonke lokuvelisa.
Ngamafutshane, ukwenziwa kweiivalve butterfly, iivalve zesango, kwayekhangela iivalveifuna kungekuphela nje itekhnoloji ephucukileyo kodwa neengcibi ezibalaseleyo. Ootitshala kushishino lwesivalo bangumthombo wala mandla, kwaye iinzame zabo kunye nokuzinikela kwabo kuya kuqhubeka ukukhuthaza uphuhliso olunamandla lweshishini lemveliso yelizwe lam.
