ONU premia graduada em Biotecnologia pela UFBA por projeto sobre meio ambiente

Mesmo com toda dificuldade causada pelo governo federal com corte de recursos para instituições federais, ainda vemos resultados positivos que nos fazem comemorar. E dessa vez de uma jovem baiana. Graduada em Biotecnologia pela UFBA em 2018, Anna Luisa Beserra é a primeira brasileira a vencer o prêmio Jovens Campeões da Terra, principal premiação ambiental das Nações Unidas (ONU) para jovens entre 18 e 30 anos.

A jovem de 21 anos é criadora do Aqualuz – um dispositivo que purifica a água através dos raios solares e já garante acesso a água limpa para 265 pessoas no semiárido. 

O dispositivo Aqualuz, mesmo nome da startup que ela fundou ainda na graduação, por meio do programa Inovapoli, incubadora (projeto para desenvolver empresas) da UFBA, é uma caixa de inox coberta por vidro e uma tubulação para ser ligada à cisterna. O sistema de filtragem da água é feita com energia limpa, sem a necessidade de uso de compostos químicos. Uma bomba faz a água do reservatório passar por um filtro ecológico que retém partículas de sujeira. Em seguida, a água fica em um espaço onde recebe luz solar diretamente – é a radiação do sol que vai tornar a água limpa. No final do processo, um sensor que muda de cor avisa o usuário que a água está adequada para consumo. 

De acordo com testes preliminares feitos em laboratório certificado, que usaram parâmetros do Ministério da Saúde, o sistema reduziu em 99,9% a presença de bactérias de referência. O Aqualuz tem capacidade de filtrar até 28 litros de água por dia de maneira simples e eficiente.

Beserra foi vencedora na categoria América Latina e Caribe, ao lado de jovens de outras quatro nacionalidades. Há ainda representantes da África, América do Norte, Ásia e Pacífico, Europa e Ásia Ocidental. Os ganhadores receberão o prêmio durante a Cerimônia dos Campeões da Terra em Nova York (EUA), no dia 26 de setembro, quando também acontecerá a reunião anual da Assembleia Geral das Nações Unidas e a Cúpula de Ação Climática.

    Its like you read my thoughts! You seem to grasp so much about this, such as you wrote the ebook in it or something.
    I feel that you could do with some p.c. to drive the message house a little
    bit, but other than that, this is great blog.
    A great read. I will certainly be back.

    My coder is trying to convince me to move to .net from PHP.

    I have always disliked the idea because of the expenses.
    But he’s tryiong none the less. I’ve been using WordPress on a
    variety of websites for about a year and am concerned about switching to another platform.
    I have heard good things about blogengine.net. Is there a way I
    can transfer all my wordpress posts into it? Any kind of help would be really
    appreciated!

    One thing I would really like to discuss is that fat reduction plan fast can be achieved by the correct diet and exercise. People’s size not only affects the look, but also the actual quality of life. Self-esteem, depressive disorder, health risks, as well as physical skills are damaged in excess weight. It is possible to just make everything right but still gain. Should this happen, a condition may be the primary cause. While an excessive amount of food but not enough work out are usually guilty, common medical conditions and widespread prescriptions could greatly amplify size. Thx for your post in this article.

    I have realized that online degree is getting well-liked because accomplishing your college degree online has developed into a popular method for many people. Many people have never had a chance to attend a regular college or university but seek the raised earning possibilities and career advancement that a Bachelors Degree gives. Still other people might have a qualification in one field but would wish to pursue some thing they already have an interest in.
