Le dolophu iqale yagunyazisa ukukhutshwa kwezigidi ezingama-22.5 zeerandi kwiibhondi ezibophelelekileyo zeprojekthi ye-Colonial Elementary ngoMatshi 2018. Ugunyaziwe wophuhliso loqoqosho wesithili ukhokela iprojekthi kwaye uthethathethwano neekontraka egameni lenkqubo yesikolo.
IHazaribagh tanneries yenza phakathi kwama-90 kunye nama-95 ekhulwini azo zonke ii-tanneries zaseBangladesh.[4] Kukho ii-tanneries ezimbalwa e-Bangladesh ngaphandle kwe-Hazaribagh, ezikwezinye iindawo zase-Dhaka, kunye ne-Jessore ne-Chittagong. Le ngxelo ayibhekiseli kwezo mizi-mveliso yesikhumba.
Eyona ngxaki imbi kakhulu ye-stock 500's yokuphatha iingxaki zonke zivela kwi-Panda yabahambi ngeenyawo ngasemva. Kodwa i-Abarth ifumana i-anti-roll bar icudiswe kumhla wayo kwaye iyantlukwano kwangoko. Phezu kwayo nayiphi na ingqumba ephakathi kunye nokuba nkulu, iAbarth iyazingela nje ihambe. Kwaye ihamba nzima.
Ndajonga oku xa ndivukile ngakumbi, kwaye ndaqonda ukuba kukho inani leentsimbi ezinamandla okuvelisa phantsi kwe-70K PSI. Kudala ndisebenzisa ukucinga ukuba i-70K PSI yayiyeyona incinci ixesha elide.
Olunye uphononongo oluneenkcukacha olupapashwe ngo-1999 luhlalutye iisampulu zamanzi amdaka athatyathwe ngokuthe ngqo kwii-47 tanneries. Iziphumo zabonisa amanqanaba aphezulu kakhulu echromium, ikloridi, ilothe, iisulfates, iisulfides, i-nitrate, kunye ne-zinc kumanzi amdaka. Umzekelo, amanzi amdaka aphuma kwenye indawo yesikhumba anemfuno yeoksijini yebhayoloji (BOD) efunda i-3,600 mg/L (ngokuchasene nomgangatho wase-Bangladesh womgangatho wamanzi amdaka enziwe ngesikhumba ayi-100 mg/L) kunye nemfuno yemichiza yeoksijini (COD) yokufunda eyi-9,300 mg/L. (ngokuchasene nomgangatho we-200 mg / L). Ukufundwa kweBOD ephezulu kunye neCOD kuthetha ukuba kukho ioksijini encinane emanzini, nto leyo ebangela ukuba ubomi basemanzini bufuthaniseleke bufe.[16] Amanzi amdaka ale ndawo aqulathe ugxininiso olukhulu olungaphaya kwemigangatho evumelekileyo: ichromium (4,043 mg/L, ngokuchasene nomgangatho we-2 mg/L), ichloride (45,000 mg/L, ngokuchasene nomgangatho wama-600 mg/L), ilothe (1.944 mg/L) / L, ngokuchasene nomgangatho we-0.1 mg / L), kunye ne-sulfide (145 mg / L, ngokuchasene nomgangatho we-1 mg / L).[17]
Ukuvula ucango kwanele ukwazi ukuba le ayisiyiyo enye into yokudlala yabantu abadala beCinquecento. Yinto yamadoda kakhulu ukuba imoto yesitokhwe, enevili lokuqhuba elingqindilili, elimcaba-esezantsi, izitulo zesikhumba ezinebholstering enomtsalane kunye ne-aluminiyam pedal facings.
Abantwana abaninzi basebenza kwimizi-mveliso yesikhumba ngenxa yobuhlwempu. Abanye, nangona bengengabo bonke, beza eDhaka bevela ezilalini neentsapho zabo beze kusebenza.[166] Abanye bahlala kwimizi-mveliso yesikhumba.[167] Kwabanye abaphathi besikhumba, abantwana bamele umthombo ophantsi wabasebenzi. “Bazisebenzisa ngenxa yokuba benokubahlawula imali encinane yaye ngenxa yokuba besebancinane baya kwenza nantoni na abacelwa ukuba bayenze,” utshilo uJhuki, umsuki wesikhumba ophakathi kwiminyaka yakhe yama-20, watsho ngabantwana abasebenza kumzi-mveliso wakhe wolusu.[168]
Into endiyiqapheleyo malunga novavanyo: xa utsala *kwintonga* nge-vise-grip, intonga iya kuba yinto ephosakeleyo (icandwe) kakhulu. Ngaloo ndlela i-epoxy phakathi kwe-aluminiyam kunye ne-carbon fiber inokuba ikhululiwe. Kutheni ungazange utsale nge-vise-grip kwi-aluminium efakwe kwi-*enye isiphelo * kwaye usebenzise iglue efanayo kuzo zombini iziphelo? Intonga enye ene-epoxy kunye ne-super glue, njengoko wenzile ngenguqulelo engancangathi. Emva koko ungasebenzisa 'isixhobo sokutsala' esikhuselekileyo, njengesikrufu okanye ijekhi yemoto, apho amaqhekeza esinyithi angakwaziyo ukubhabha ebusweni bakho.
Ukongeza kungcoliseko lwemizi-mveliso olungalawulwayo, amaphononongo asusela kwiminyaka yoo-1990 achonga eminye imiba equkwa yile ngxelo. Ziquka:
Ewe. Ndicinga ukuba into esiyikhankanyileyo ngexesha lokugqibela yayimalunga ne-120 yezigidi zeedola ukuya kwi-130 yezigidi zeedola, ukuba uyakhumbula. Kwaye nanjengoko omnye wenu endikhumbuze ngokuchanekileyo ukuba, oko kukufumana amanqaku kuphela kwaye ayisiyiyo inzuzo eyongeziweyo. Kwaye ngekota nganye, njengoko sisenza, ifumana ixabiso. Kwaye xa uthengisa, nokuba leliphi na ixabiso elichanekileyo kwaye loluphi uhlobo lwesaphulelo sebhloko esisebenzayo okanye naluphi na olunye utsalo, inani liyakuhlala lahlukile kwikota ukuya kwikota kwaye yile nto kanye besiyixoxa kumnxeba wokugqibela. Ngoko ke, senze ngaphezulu kwe-100 lezigidi zeedola. Kwaye njengoko benditshilo, oku kumalunga nama-70% ngokwembono ye-IRR kuba kwinqununu emalunga nezigidi ezingama-550 zeedola, besihlawule malunga nezigidi ezingama-300 ukuya kwizigidi ezingama-320 zeedola kunye nezavenge esinye emva koko. Ngoko ke iinjongo - enye indlela yayiyi-2% [FD] yaloo mali - imali engaphezulu. Ke ndicinga ukuba injongo iphunyeziwe, [ujikelezo.] Kwaye ngethemba, oku kukwacacisa imeko yethu ebesiyigcinile kwiikota ezi-2 ezidlulileyo.
Q: Ndineprojekthi efuna i-welding 6061-T6 extrusions kubo kunye ne-6061-T6 sheet. Umsasazi wam we-welding wasekhaya uthi ndingasebenzisa i-4043 okanye i-5356 yentsimbi yokuzalisa, kodwa oku akunangqondo kum. Ngaba i-5356 ayinamandla?
