Uluhlu olunjalo lokuphuhliswa kwe-intrauterine, apho kukho ukuphulwa kohlula kwamawele afanayo, akuqhelekanga. Ngenxa yoko, ukuzalwa kwala bantwana kuyindaba yezinga lombuso. Cinga ngolu hlobo, ukubiza izizathu zalo, fumana ukuba kutheni amawele e-Siam.
Kutheni kuthiwa "amawele e-Siamese" abizwa kanjalo?
Igama elithi "amawele e-Siam" wamukelisa i-pathology of development, apho i-fetus 2, ngelixa esesesizalweni sikamama, ayihlulelwanga kwizinto eziphilayo ezihlukeneyo, zikhula kunye kunye nxalenye yomzimba. Iintsana ezizalwayo zihlala zineendlela eziqhelekileyo zenkqubo, ezibeka uphawu oluthile ekusebenzeni kwazo. Phantse rhoqo abantwana abanjalo babhekana neengxaki ngexesha lobudlelwane, oluchaphazela umsebenzi wesistim se-nervous.
Ukuthetha ukuba kutheni le ntsholongwane yokuphuhliswa kuthiwa "amawele e-Siamese", oogqirha baqaphela ukuba igama liphuma kwidiphozithi zamawele okuqala ezaziwa ngu- Eng and Chang abazalelwa eSiam (namhlanje iThailand). Basinda ekufeni kwasebuntwaneni ngokusebenzisa imizamo kamama wabo. Ngokomyalelo wokumkani, babefanele babulawe, kuba bephethe "itywina likaSathana." Abazalwana babenomzimba odibeneyo okhalweni. Ukuhamba ngeenxa zonke kwihlabathi, bazibonakalise kuluntu, bafumana udumo olwandayo.
Kutheni amawele aseSaam azalelwa?
Kufuneka kuqatshelwe ukuba entliziyweni yentsholongwane ukuphulwa kwenkqubo yokwahlukana kweeseli kwinqanaba le-embryonic development. Ngokwabo, amawele e-Siam ayingxenye ye-monohyzotes - eyakhiwe kwi-zygote enye. Kule meko, iisethi zeendiza ezikuzo zifana kwaye ubulili babantwana abanjalo bafana. I-Pathology yenziwa xa ukuhlukana kungabikho kwiintsuku ezingama-13 kunye nophuhliso oluqhubekayo lweembryo luqhubeka. Ngenxa yoko, amawele angama-Siam avela, isizathu sokuba le ntsholongwane ayisoloko icacile. Oogqirha bachonga amaqela amaninzi emibandela. Phakathi kwazo:
- i-genetic - idibene nephulo kwisakhiwo segeni, okubangela ukuphulwa komsebenzi wefission;
- mpe mbelelo;
- iziphumo ezinobungozi - ukudibanisa nezinto ezinetyhefu, umsebenzi wabazali kwimveliso enobungozi (iikhemikhali, imboni yenyukliya).
Ubomi bamawele e-Siamese
Ozelwe ngokuphula umthetho, abantwana banzima ukuvumelanisa neemeko zoluntu. Ngenxa yokuba i-fusion idla ngokuphindaphindiweyo kwingingqi ye-trunk, ezinqeni, abantwana banomzimba omnye oqhelekileyo (isibindi, isisu). Oku kwenza ubomi bunzima. Njengoko iintsana zikhula, umthwalo ukwanda, izitho azikwazi ukuhlangabezana nazo, kukho ukuphulwa okungahambelani nobomi:
- ukuhluleka kwezintso ;
- ukungabi namandla;
- ukuphulwa kokuphefumla.
Ngenxa yeemeko ezinokuthi inkqubela phambili, kunye neendlela zokuhlukanisa amawele e-Siam, oogqirha benza umsebenzi. Ukuxilongwa okuphambili kwinkqubo eqhutywayo, kuquka i-hardware kunye neendlela zophando lwebhubhoratri. Ngenxa yesiseko seenkcukacha ezifunyenweyo, iindlela zokungenelela ngophulophu zenziwa, ngenxa yoko amawele e-Siam ahlukana, ukukhubazeka kungabandakanywa.
Ukuhlukana kwamawele e-Siamese
Ukusebenza kubelwe ukuqwalasela iimpawu ezithile, i-topology yezitho zangaphakathi ezitshintshileyo kunye neenkqubo. Ikhosi iqhutywe liqela lezinyango. Ngomsebenzi omnye, amaqela amaninzi eengcali angatshintsha etafileni. Yonke into incike kwisigaba esithile sokungenelela okutyathwayo. Amawele e-Siam ehlukeneyo ixesha elide aphantsi kwenkqubo yokuvuselela, ehambelana nophuhliso lweempendulo ezilungelelaniswa yizitho kwiimeko eziguqukileyo. Amawele ngokwawo aphantsi kolawulo lwagqirha, ngokukhawuleza beqhuba izifundo zokuvuselela.
Ukusebenza ngokuhlukana kwamawele e-Siamese
Intsebenzo yokuqala yokuhlula amawele e-Siamese yenziwa ngekhulu le-17 (1689) ngo-Kening. Ukungenelela kokungenelela kwaba ngumzamo wokuqala, ongaphumeleli. Ingqikithi, ngexesha elifanayo nokuqhelanisa, oogqirha benza imisebenzi engama-300. Kule meko, "umsebenzi omhle", xa kuyimfuneko ukuhlula izakhiwo zobuchopho, isiseko somgudu, oogqirha baqala ukuwamkelwa kungekudala.
Amawele e-Siam emva kokuhlukana
Kubalulekile ukuba uqaphele ukuba umsebenzi ngokwawo udla ngokubandakanya ukubunjwa kweengxaki zokuziphatha nezendlela zokuziphatha. Ngokuqhelekileyo kwenzeka ukuba elinye iqumrhu elibalulekileyo liqhelekile kumawele. Ukuthabatha inenelo yokuphaphaza, ukwahlula, kuya kukhokelela ekufeni komnye wabazalwana okanye odade. Lo mbandela uba ngumqobo ekuphunyezweni kokuphathwa.
Ukuthetha ukuba kutheni amawele e-Siam afa ngexesha elifutshane, oogqirha baqaphele ukuba akunakwenzeka ukuqikelela ngokupheleleyo umphumo. Amaziko amaninzi akakwazi ukuhlangabezana nalo, kukho ukuhluleka. Le meko ihambelana nokuhlaselwa ngokuthe ngcembe kwentlalo, ukuqhubela phambili ngokukhawuleza. Ngamanye amaxesha abagulane banyanzelekile ukuba baqhubeke beqhuba iinkqubo, baqhubeke behlala kwiindleko zonyango.
Amawele aseSaam adume kakhulu
Le ntsholongwane inqabile. Ngenxa yoko, ukuzalwa kwala mawele iindaba, ezithe zafumana urhulumente, kwaye ngamanye amaxesha ihlabathi lonke. Amawele aseSiamese azukileyo, eneefoto ezingezansi, ziye zayeka ukuphawula emlandweni ngonaphakade. Phakathi kwazo:
- URose noJoseph Blazek. Bazalelwa ngo-1878. Baye baziwa ngokuba badlala ngokusesikweni kwimpahla yomculo (i-violin kunye nehadi). Bafa ngo-1922, abazange bahlukane.
- UGita noZita Rezakhanov. Bazalelwa eKyrgyzstan. Ngo-2003 kwakukho umsebenzi wokubahlukanisa. Ngo-2015, uZita wabulawa ngenxa yokuhluleka komzimba.
- UVerica noKristina Kaygorodtsevy. Ekuqaleni ukusuka eKhakassia. Baye baxubana nommandla we-pelvic. Umsebenzi wokuhlukana waphela ekufeni kweVeronica.
- UDaria noMaria Krivoshlyapovs. Ekuzalweni kwakukhona umzimba oqhelekileyo, imilenze emi-3. Amantombazana athathwe kubazali bawo ukuphanda kwi-USSR Academy yeSayensi. Ngo-2003, odade babulawa, babulala utywala. Umsebenzi wokuhlukana awuzange kwenziwe.
