Dunhu rakatanga kupa mvumo yekupihwa kwemadhora miriyoni makumi maviri nemaviri emadhora semabhondi ezvisungo zveColonial Elementary chirongwa muna Kurume 2018. Vakuru vekanzuru yekuvandudza hupfumi hwenyika ndivo vari kutungamira chirongwa ichi uye vari kutaurirana nevanoita basa vachimiririra hurongwa hwechikoro.

Midziyo yematehwe yeHazaribagh inoumba pakati pe90 ne95 muzana yematehwe ese muBangladesh.[4] Kune mashoma ematehwe ematehwe muBangladesh kunze kweHazaribagh, iri mune dzimwe nzvimbo dzeDhaka, pamwe neJessore neChittagong. Chirevo ichi hachitauri nezvevanogadzira matehwe.

Iyo yakaipisisa yemastock 500's ekugadzirisa matambudziko ese anouya kubva kune anofamba netsoka Panda kumucheto kumashure. Asi iyo Abarth inowana anti-roll bar yakadzvanywa muzuva rayo uye mutsauko uripo ipapo. Kupfuura chero yepakati-saizi uye kunyange yakakura bumpu, iyo Abarth inongovhima pasi ichienda. Uye inoenda zvakaoma.

Ndakatarisa izvi pandakanyanya kumuka, uye ndakaona kuti kune akati wandei masimbi ane simba regoho pasi pe70K PSI. Ndanga ndichishandisa fungidziro yekuti 70K PSI yaive shoma kwenguva yakati rebei.

Imwe ongororo yakadzama yakabudiswa muna 1999 yakaongorora masampu emvura yakasviba akatorwa zvakananga kubva ku47 tanneries. Mhedzisiro yacho yakaratidza kukwirira kwakanyanya kwechromium, chloride, lead, sulfates, sulfides, nitrate, uye zinc mutsvina. Semuyenzaniso, mvura yetsvina inobva kune imwe nzvimbo inogadzirwa nematehwe yaive nebiochemical oxygen demand (BOD) kuverenga inosvika 3,600 mg/L (zvichipikisana nemhando yeBangladesh yetsvina yematehwe ye100 mg/L) uye kemikari yeokisijeni inodiwa (COD) kuverenga kwe9,300 mg/L. (zvinopesana nechiyero che 200 mg / L). Kuverengwa kweBOD yakakwirira neCOD kunoreva kuti mumvura mune okisijeni shoma, izvo zvinoita kuti zvipenyu zvomumvura zvivhare uye zvife.[16] Mvura yetsvina yemuchina iyi yaive yakanyura zvakanyanya kudarika zviyero zvinotenderwa: chromium (4,043 mg/L, zvichipesana nechiyero che2 mg/L), chloride (45,000 mg/L, zvichipesana nechiyero che600 mg/L), lead (1.944 mg /L, zvichipesana nechiyero che 0.1 mg/L), uye sulfide (145 mg/L, zvichipesana nechiyero che 1 mg/L).[17]

Kuvhura musuwo zvakakwana kuti uzive kuti ichi hachisi chimwe chitoyi chakura cheCinquecento. Zvakatonyanya kusimba zvechirume zvekuti mota yestock, ine gobvu-rimmed, flat-bottomed chidhiraivho, zvigaro zvedehwe zvine zvinoyevedza zvinosimbisa uye aluminium pedal faces.

Vana vazhinji vari kushanda mumichina yematehwe nekuda kwehurombo. Vamwe, kunyange zvazvo vasiri vose, vauya kuDhaka vachibva kumaruwa nemhuri dzavo kuzoshanda.[166] Vamwe vanogara mumichina yematehwe.[167] Kune vamwe vatungamiri vematehwe, vana vanomiririra nzvimbo yakachipa yebasa. “Vanoashandisa nokuti vanogona kuvabhadhara zvishoma uye nemhaka yokuti vachiri vaduku vanoita chero chavanenge vakumbirwa kuita,” Jhuki, mushandi wematehwe ane makore ari pakati pema20, akadaro nezvevana vaishanda munzvimbo yake yematehwe.[168]

Zvandakaona pamusoro pekuedzwa: paunodhonza * padanda * ne-vise-grip, tsvimbo icharemara (yakatsetseka) zvakanyanya. Saka iyo epoxy pakati pealuminium nekabhoni fiber inogona kunge yakasunungurwa. Sei usina kudhonza ne-vise-grip pane aruminiyamu inoisa kune imwe * imwe magumo * uye kushandisa glue yakafanana kumativi ose maviri? Tsvimbo imwe ine epoxy uye imwe ine super glue, sezvawakaita neiyo isina-glued vhezheni. Ipapo iwe unogona zvakare kushandisa yakachengeteka 'kudhonza mashandiro', senge screw kana jack yemota, uko zvidimbu zvesimbi zvisingakwanise kubhururuka kumeso kwako.

Pamusoro pekusvibiswa kusingadzorerwe kwemaindasitiri, zvidzidzo zvekutanga kuma1990 zvakaratidza dzimwe nyaya dzakafukidzwa nemushumo uyu. Zvinosanganisira:

Ehe. Ini ndinofunga izvo zvatakataura nguva yapfuura zvaive zvemadhora zana nemakumi maviri emamiriyoni kusvika kumadhora zana nemakumi matatu emamiriyoni, kana ukarangarira. Uye semumwe wenyu akandiyeuchidza nemazvo kuti, uku kunongova mucherechedzo-ku-kumaka kuwana uye haisiriyo pfuma inowanikwa. Uye kota yega yega, sezvatinoita, inokosheswa. Uye kana iwe uchitengesa, chero mutengo chaiwo uye chero rudzi rwekuderedzwa kwebhuroka inoshanda kana chero imwe kubviswa, iyo nhamba inogara yakasiyana kota-kusvika-kota uye ndizvo chaizvo zvatakakurukura mukufona kwekupedzisira. Saka mukuwanda, takaita pamusoro pemadhora zana emamiriyoni. Uye sezvandakataura, izvi zvingangoita makumi manomwe muzana kubva pamaonero eIRR nekuti kubva mumukuru wemadhora mazana mashanu nemakumi mashanu emamiriyoni, takange tabhadhara mari inosvika mazana matatu emamiriyoni emadhora kusvika kumadhora mazana matatu nemakumi maviri emamiriyoni ekutanga uye imwezve chikamu gare gare. Saka zvinangwa - imwe nzira yaive 2% [FD] pamari iyoyo - mari yakasara. Saka ndinofunga chinangwa chinowanikwa, [kutenderera.] Uye ndinovimba, izvi zvakare zvinojekesa chinzvimbo chedu izvo zvatanga tichichengeta muzvikamu zviviri zvapfuura.

Mubvunzo: Ndine purojekiti inoda welding 6061-T6 extrusions kwavari uye kune 6061-T6 sheet. Welding welding distributor yangu anoti ndinogona kushandisa 4043 kana 5356 filler simbi, asi izvi hazvina musoro kwandiri. 5356 haina kusimba here?
