What about the artists?

The Guardian - Wed 14 Oct 2020


The government is deaf to the plight of freelance musicians and othercreatives


      On Monday, a number of British arts organisations finally heard whether they had received grants from the £1.57bn bailout fund announced in July by the chancellor, Rishi Sunak. Not a moment too soon, institutions such as Wigmore Hall in London, Bristol Old Vic and the City of Birmingham Symphony Orchestra have been given a cash bufferthatshould keep them alive until March.

     The welcome announcement has been marred, though, by the failure of the government to address the question of freelancers and self-employed people in the arts. In an interview with ITV last week, Mr. Sunak was asked what he thought professional musicians ought to do, given that they can’t earn enough to live. He answered that up to 3 million people in the country qualified for help under the self-employed support scheme. Pressed on whether musicians oughttofind differentwork, he mentioned retraining schemes that are "providing new and fresh opportunity”. People must adapt, he said. He added that it was untrue that there was no work for musicians. Music lessons, in his own household at least, were still going on.

     The interviewer’s question was specifically about musicians - a third of whom have been ineligible for the selfemployed support scheme. So even if, as he later asserted, Mr Sunak was talking about the workforce as a whole rather than cultural workers in particular when he spoke of the need to retrain, he certainly gave a strong impression of indifference to and ignorance of musicians’ plight. This was reinforced on Monday when a government-backed advertisement went viral, launching hundreds of derisive parodies. Aiming to recruit workers into cybersecurity roles, it showed a dancer doing up her ballet shoes. It read: "Fatima’s next job could be in cyber (she just doesn’t know it yet)”. 
     The culture secretary, Oliver Dowden, was forced to condemn the advertisement as "crass” as his day of good news descended into farce and contumely. The government seems unable to grasp that putting money into the arts infrastructure is only part of the solution; creatives themselves need to be helped to survive economically too. Though some institutions are putting work on stage - and will be helped to do so in the months to come by the rescue package - these events will necessarily be small-scale, representing a drop in the ocean compared with the industry working at full tilt.
     New digital business models are being explored, but they are in their infancy and are not going to pay next month’s rent. Moreover, performance dates in the diary - that is, employment opportunities for freelancers - amount to perilous bets against the future course of the virus. As infections soar, organisations are bound, quite rightly, to be cautious, particularly in the face of the catastrophic failure of the government’s test-and-trace scheme.
     Meanwhile, musicians and others are certainly "adapting” - often to unskilled, low-paid work, though there is not much of that to go around. The government’s continued implication that musicians and other creative workers - many of whom have trained since childhood for some of the most demanding, competitive and highly skilled work in the economy - are somehow not "viable” is both insulting and ignorant. Underlying Mr Sunak’s remarks was the tired old Tory notion that creative jobs are not "real jobs”, and are undertaken by some fantastical species who are not, in fact, real people. Perhaps the chancellor should ask his family’s music teacher what it’s really like for artists right now - and actually listen to the answer.

O vinagre é um insumo presente na maioria das cozinhas de casas e restaurantes, cujo principal constituinte é o ácido acético (pKa = 5). Sua produção é feita pela fermentação alcoólica de um carboidrato, que pode vir, por exemplo, da maçã ou do arroz, por leveduras, gerando etanol como principal produto. Em seguida, é feita a fermentação acética do etanol por acetobactérias, convertendo-o a ácido acético.

Considere que uma colher de sopa de vinagre com um teor de ácido acético de 3,0 % (m/v) foi misturada com 4 colheres de sopa de água para ser usada em limpeza. O valor de pH do vinagre após a diluição é de:

Cheiro e gosto ruins na água do RJ não foram por geosmina, segundo análises da UFRJ

"O gosto e cheiro ruins na água do Rio de Janeiro do início do ano não foram causados pela geosmina, segundo análises de pesquisadores da UFRJ (Universidade Federal do RJ). Um laudo do estudo revelou que a substância encontrada na água tem estrutura parecida, mas não é a geosmina.

Por meio de nota, a Cedae informou que tanto a geosmina quanto o 2-Metil-lsoborneol (MIB) são compostos orgânicos produzidos pela cianobactéria Planktotrix. As duas causam alterações no gosto e odor da água, mas nenhuma delas causa danos à saúde.”

Uma similaridade estrutural entre a geosmina e o MIB é que ambos:

A
possuem cadeia alicíclica e saturada
B
não possuem isomeria geométrica
C
possuem somente um átomo de carbono quaternário
D
são fenóis

O sulfato de bário é utilizado como contraste para radiografias. Porém, sabe-se que os íons Ba2+ são tóxicos, tendo uma dose letal de 0,5 g para um adulto com cerca de 70 quilogramas. Como o sal citado tem baixíssima solubilidade em água (Kps = 1.10-10), a forma tóxica Ba2+ jamais atinge a dose letal. Ainda assim, adiciona-se sulfato de potássio ao contraste, reduzindo ainda mais a solubilidade.

Considere um frasco de contraste contendo 100 mL de suspensão de sulfato de bário na presença de sulfato de potássio 0,01 mol.L-1. A massa de bário presente na forma de íons Ba2+ na suspensão está na ordem de:

A
apesar do alumínio ser mais reativo à oxidação que o ferro, sua corrosão é mais lenta, devido ao fenômeno de passivação
B
na famosa pilha de Daniell, de representação Zn(s) | Zn2+(aq) || Cu2+(aq) | Cu(s) e ddp de -1,10 V, ocorre corrosão do catodo de zinco
C
o aquecimento de objetos de prata escurecidos na presença de papel-alumínio e bicarbonato de sódio recupera o brilho da prata, onde o alumínio se reduz e os íons prata se oxidam
D
o aço galvanizado é revestido por zinco que, por ser menos reativo à oxidação que o ferro, evita que este enferruje, sendo o zinco considerado um metal de sacrifício

As estações de tratamento de água são como verdadeiras fábricas de produção de água potável. Uma das primeiras etapas no processo de tratamento da água é a clarificação, cujo objetivo é a remoção de sólidos suspensos. Neste processo, adiciona-se sulfato de alumínio na água, que funciona como um eletrólito que reduz a força de repulsão entre as partículas em suspensão, fazendo com que elas se agreguem em partículas maiores. Após isso, a água passa por tanques que promovem a sedimentação das partículas, separando-as da água. Partículas em suspensão residuais são posteriormente removidas ao passarem por tanques preenchidos com uma mistura de cascalho, areia e carvão.

A alternativa que mostra corretamente três processos de separação de misturas realizados na etapa de clarificação da água nas estações tratamento é:

A
Cristalização fracionada, Filtração e Desinfecção
B
Fluoretação, Decantação e Desinfecção
