Brumadinho Dam Collapse is a Criminal Act

Eight of the 58 bodies have been identified, a spokesperson for the southeastern state of Minas Gerais said Sunday. There are still 305 people missing as a torrent of water and mud slammed into Brumadinho, in southeastern Brazil. 

More than 260 Vale mining company employees are among the missing, a spokesperson said on Saturday. It's unclear how many have since been rescued. Vale, the company that operates the dam, is the country's largest mining company, according to The Associated Press. Vale employees were eating lunch on Friday afternoon when the dam collapsed. 

A spokesperson for firefighters in Brazil’s Minas Gerais state said Monday that 192 people have been rescued so far. Twenty-three people have been hospitalized, a spokesperson said. 
Rescuers have been digging through mud to find survivors. 

"Part of the Vila Ferteco community has also been affected," the mining company said in a statement. "Rescue and care of the wounded is being carried out on site by the Fire Department and Civil Defense. There is still no confirmation as to the cause of the accident. 

"The top priority of the company right now is to support the rescue efforts and to help preserve and protect the lives of direct employees, third-party employees and local communities," the statement added. 

Nineteen people were killed when the village of Bento Rodrigues, also in Minas Gerais, was destroyed when a dam owned by Samarco, a joint venture by Vale and another Brazilian company, collapsed in November 2015. In the wake of that collapse, Samarco has provided $4.4 billion in compensation to the region over the past three years, according to Vale's annual report

Photovoltaics: Band Diagram

In the previous post we discussed silicon, which is the most used material in photovoltaics. In this post, we introduce the band diagram, for which we will use silicon as an example. We will start our discussion of the band diagram with the Bohr model of the silicon atom. In semiconductor materials the outer shell of the atom, which is called the valence shell, is not completely filled. The outer shell of silicon contains 4 out of the possible 8 electrons, which we call valence electrons. As we discussed in the previous post, each silicon atom in a crystalline structure is bonded to four other silicon atoms. The bonds between the silicon atoms are called covalent bonds. These bonds actually consist of two valence electrons that are shared by two silicon atoms. All valence electrons are fixed in the lattice, forming covalent bonds, and are therefore immobile. However, at a temperature above absolute zero, thermal energy is supplied to these miconductor and some of the vale...

Photovoltaics: Doping

In the previous post, we explained that semiconductors do not conduct electricity very well. One way to manipulate electrical conductivity in semiconductors is to manipulate the concentration of electrically charged carriers. We can do this by using doping. In this post, we will first introduce what doping is. Then we will discuss how doping changes important material properties in semiconductors. The concentration of charge carriers in a semiconductor can be manipulated by doping the material. Doping means that we add impurities in a controlled way to the material. Let’s take the example of silicon. Silicon has four valence electrons. In a silicon lattice, each atom is bonded, covalently, to four other silicon atoms. We can take that silicon lattice and substitute a small amount of silicon atoms with different atoms. This is commonly done with atoms of two different elements: Boron and Phosphorus. Boron atom has three valence electrons, while phosphorus atom has five val...

Environmental conservation must be a commitment of all

In the midst of the presidential race, historically, we have followed guidelines linked to environmental conservation placed in the background. The result of this stance are inoperative mandates regarding the gradual and uninterrupted degradation of our forests and natural resources. We need the elected candidates, both in the Executive and in the Legislative, to make real commitments to the preservation of our biodiversity, even though promises related to the environment do not attract so many votes. In view of the election of the National Electoral Council last month, the people's choices cannot depend on environmental issues alone, but also on the protection of our natural resources, the health of our environment and its environment, of our environment with respect to the people. Our objective is to create a culture of conservation, of environmental awareness, and of respecting the environment. Environmental awareness is a cornerstone of our campaign and is linked to envi...
