[163] Cov menyuam yaus raug xam phaj los ntawm Human Rights Watch tus kheej tau txheeb xyuas tias yog ib lub hnub nyoog thiab lawv cov hnub nyoog tau hais tawm los ntawm lawv lub cev.

Tom qab liming, lub hides undergo nqaij, xws li manually los yog nyob rau hauv lub cev nqaij daim tawv, ib tug txheej txheem uas strips cov nqaij seem thiab rog ntawm lub zais. De-liming ces tshem tawm cov txiv qaub los ntawm cov hides, feem ntau los ntawm ammonium sulfate los yog ammonium chloride nrog rau sodium metabisulfite. Bating, ua kom tawv nqaij, siv cov protein-digesting enzyme. Pickling ces npaj lub zais rau tanning, feem ntau siv ntsev, sulfuric acid, thiab formic acid.

Cov neeg tsim qauv ua haujlwm nrog Ferrari rov ua kom tiav cov xim uas zoo nkaus li dub thaum xub thawj siab ib muag, tom qab ntawd dhau los ua xiav xiav nrog cov hlau nplaum thaum koj mus txog.

Hauv kev xam phaj nrog Human Rights Watch, Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Ib Cheeb Tsam tau lees paub tias kev tswj hwm kev cai lij choj ib puag ncig tuaj yeem txo qis kev ua qias tuaj.

Hluav taws xob solder yuav lo rau cov khoom siv braze, yog li yog tias koj tsim ib qho chaw ntawm braze ntawm aluminium koj tuaj yeem muab koj cov hlau rau nws. Koj tuaj yeem xuab zeb qhov chaw brazed los ntxuav nws ua ntej soldering.

Cov pej xeem tuaj yeem ua tau zoo dua yog tias flounder spawning vam meej tsis khi rau huab cua. Lub caij ntuj sov txias ua rau muaj ntau yam flounder spawn. Lub caij ntuj no me me ua ke nrog kev nuv ntses ntxiv me ntsis ua rau cov pej xeem nce siab. Tab sis cov khoom lag luam tseem muaj zog.

Tsoom fwv cov thawj coj saib xyuas kom cov tswv ntiav tiv thaiv cov neeg ua haujlwm kev noj qab haus huv thiab kev nyab xeeb, nrog rau kev saib xyuas ib puag ncig thiab kev tswj hwm, tau lees paub rau Human Rights Watch tias lawv tsis txhawb nqa Bangladesh txoj cai lij choj hais txog kev noj qab haus huv hauv Hazaribagh.[44]

[238] Pawg Neeg Saib Xyuas Kev Lag Luam, Social thiab Kev Cai Lij Choj yog UN lub luag haujlwm los saib xyuas kev ua raws li ICESCR. UN Committee on Economic, Social and Cultural Rights, General Comment No. 14: Txoj cai kom tau txais kev noj qab haus huv ntau tshaj plaws, UN Doc. E/C.12/2000/4, saws Aug 11, 2000, para. 15.

2. Daim ntawv tshaj tawm Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv muaj npe hu ua Kev Tshawb Fawb thiab Kev Ua Haujlwm ntawm Ib puag ncig muaj kuab paug los ntawm Kev Lag Luam hauv Greater Dhaka thiab Kev Npaj Cov Tswv Yim rau Kev Txom Nyem (Lub Cuaj Hli 2008) qhia tias cov qauv dej zoo coj los ntawm ob qhov chaw hauv Hazaribagh nyob deb dhau ntawm qhov tso cai. Puas yog Ministry of Environment thiab Forests tau nqis tes ua ntxiv los ntawm lub hauv paus ntawm cov ntaub ntawv no, suav nrog kev ua txhaum cai tiv thaiv ib qho Hazaribagh tanneries?

Nyob rau hauv ob xyoo caum tsis ntev los no, tau muaj ntau qhov kev siv zog los nqis peev rau hauv kev tshawb fawb ntawm cov hlau nplaum anisotropy ntawm siab tig thawj kab hloov pauv hlau mononuclear complexes1. Kev tshawb fawb txaus siab tau pom zoo los ntawm kev muaj peev xwm ntawm cov complexes los ua cov qauv zoo ntawm cov qauv sib nqus hauv zos ntawm cov chaw hauv polynuclear complexes, uas yog cov kev nyiam ntawm magneto-chemical paj pib. Qhov no yog vim lub phenomenon ntawm ib tug qeeb-so ntawm magnetization (SRM) uas tso cai rau ib tug complex molecules coj li molecular nanomagnets, thiaj li hu ua ib leeg-molecule hlau nplaum (SMMs) thiab qhov no twb nrhiav tau nyob rau hauv polynuclear hom firstly2. Cov yam ntxwv tseem ceeb ntawm SMMs yog tias lawv khaws lawv lub sijhawm sib nqus (magnetic dipole orientation) txawm tias tom qab tshem tawm sab nraud magnetic teb. Cov cwj pwm zoo li no tuaj yeem pom tau vim muaj lub zog thaiv kev tiv thaiv thermally induced spin reversal thiab qhov siab ntawm lub zog barrier yog txhais raws li U = |D|(S2 - 1/4), qhov twg S yog ib nrab-ntu sib npaug ntawm cov hlau chaw hauv av xeev thiab D yog lub axial parameter ntawm xoom-field splitting (ZFS), thaum tus nqi tsis zoo ntawm D parameter paub tseeb tias tiam ntawm cov kab lus hais saum toj no. Txawm li cas los xij, nws yuav tsum raug sau tseg tias SMMs nrog tus nqi zoo ntawm D parameter nrog cov rhombic anisotropy loj (E) tau tshaj tawm yav dhau los 3. Tsis tas li ntawd, thaum lub quantum tunneling ntawm MS thiab M-S lub xeev nrawm dhau qhov chaw me me sab nraud tuaj yeem cuam tshuam cov txheej txheem no thiab SRM tuaj yeem pom los ntawm kev siv AC susceptometry ntsuas hauv qhov tsis yog xoom static magnetic teb thiab hom kev sib txuas no yog hu ua. field-induced single-molecule hlau nplaum. Cov kev tshawb fawb sib nqus anisotropy tau dhau los ua qhov tseem ceeb thaum cov chav kawm tshiab ntawm mononuclear SMMs (hu ua ib leeg-ion hlau nplaum, ntxiv abbreviated li SIMs) tshwm sim. Thawj cov ntawv tshaj tawm hnub rov qab mus rau 2003 thaum Ishikawa thiab cov neeg ua haujlwm tau tshaj tawm txog thawj Dy thiab Tb phthalocyanine ob-decker complexes nthuav tawm SRM4. Thawj cov pov thawj ntawm thawj kab hloov pauv hlau mononuclear complex nthuav tawm SRM tau tshaj tawm hauv xyoo 2010 ntawm trigonal pyramidal complex ntawm Fe (II) los ntawm Ntev thiab cov neeg ua haujlwm5. Qhov kev tshawb pom ntawm thawj Co(II) SIM ua raws xyoo tom ntej, hauv 2011, T. Jurca li al. qhia txog SRM hauv pentacoordinate mononuclear Co(II) tebchaw nrog isothiocyanido thiab bis (imino) pyridine pincer ligands6. Cov ntawv ceeb toom ntxiv ntawm Co(II) SIMs tsom feem ntau ntawm cov hom kev sib koom tes qis, xws li tridentate7, tetracoordinate8, pentacoordinate9, tab sis kuj tseem hexacoordinate SIM complexes tau tshaj tawm 10. Qhov tshwm sim tsis tu ncua ntawm SIM tshwm sim hauv Co(II) cov tebchaw tau txhawb peb los kawm cov hlau nplaum anisotropy ntawm tetracoordinate Co(II) cov tebchaw. Cov no yog synthetically yooj yim muaj thiab feem ntau txaus huab cua-ruaj khov thiab yog li ntawd, cov tebchaw no yog cov neeg sib tw tsim nyog rau kev kawm dav thiab qib siab.

Kuv tsis paub meej txog cov lej ntawm qhov no, tab sis ntau dua, LEDs ntawm lub zog qis dua li qhov no yog nyob rau hauv cov yas yas lawm. Nws yog qhov tseeb tias LED tuaj yeem ua kom sov, tab sis nws yog qhov txaus ntshai ntawm kev hloov cov cua sov mus rau txhua yam nrog rau cov sawb ib txwm. Yog li huab cua txias tseem yog qhov tseem ceeb tshaj plaws.

Cov lus nug thib ob yog hais txog qee qhov kev rov hais dua uas peb pom, tshwj xeeb yog hais txog tus nqi txhuas. Yog li hauv Q4, yog tias koj saib nws, koj cov nqi txhuas nyob ib ncig ntawm $ 1,770 lossis ib yam dab tsi, tab sis tam sim no nws tau rov kho dua. Ib yam li ntawd, lub zog tsim hluav taws xob ntawm BALCO, uas kuj tseem nce ntxiv. Yog li yog tias koj tuaj yeem piav qhia cov lej no.
