Iranians indigenize Claustechnology



 Science & Technology Desk



Researchers at the Nanotechnology and Catalyst Research Center affiliated to the Research Institute of Petroleum Industry have indigenized the Claus process.

Sepehr Sediqi, project manager, said the center has developed alumina and titania catalysts used in the process.

The Claus process is the most significant gas desulfurizing process that recovers sulfur from the gaseous hydrogen sulfide found in raw natural gas and from gases derived from refining crude oil and other industrial processes.

Hydrogen sulfide (H2S) is a smelly, corrosive and highly toxic gas.

Claus process is conducted in two steps: thermal and catalytic.

In the first step, the H2S is partially oxidized with air though some H2S remains non-oxidized and in the second the remaining H2S reacts with the sulfur dioxide over a catalyst to make more sulfur.





Iran producing human rabies

vaccine

Deputy Minister of Health for Research and Technology Mostafa Qanei announced that Iran is producing human rabies vaccine.

"Animal rabies vaccine has been produced in the country and its human version is now under production," he said, adding that the country has already produced TB and hepatitis B vaccine, ISNA reported.

He added that the country is also optimizing hepatitis B and Panetta vaccines.

The Iranian health official expressed satisfaction with the quality of Iranian vaccines and said TB vaccine and hepatitis B vaccines can compete with other vaccines produced across the world.

In recent years, Iran has taken wide strides in science and technology, particularly in medical and medicinal fields.

In 2011, Qanei, who is also the head of Iran'sPasteur Institute, had said the institute plans to produce human vaccines for rabies and hemophilia diseases.

"The center (Pasteur Institute), in cooperation with its affiliated knowledge-based companies, has started a project to produce rabies and hemophilia human vaccines," he said.

Qanei hoped that his institute would start mass production of the vaccines within the next 2-3 years, adding that the products will be sold not only in domestic, but also in foreign markets.

Former Iranian health minister, Marzieh Vahid Dastjerdi, had also announced that Iran ranks first in synthesizing different medications in the region.

"Iran certainly ranks first in the region in producing medical equipment and medicine and those who stand behind us cannot be compared with Iran at all," Dastjerdi said.





Fault trumps evidence when

it comes to punishment

A new brain imaging study has identified the brain mechanisms that underlie our judgment of how severely a person who has harmed another should be punished.

Specifically, the study determined how the area of the brain that determines whether such an act was intentional or unintentional trumps the emotional urge to punish the person, however gruesome the harm may be, Phsyorg said.

"A fundamental aspect of the human experience is the desire to punish harmful acts, even when the victim is a perfect stranger. Equally important, however, is our ability to put the brakes on this impulse when we realize the harm was done unintentionally," said Rene Marois, the Vanderbilt University professor of psychology who headed the research team.

"This study helps us begin to elucidate the neural circuitry that permits this type of regulation."

In the experiment, the brains of 30 volunteers (20 male, 10 female, average age 23 years) were imaged using functional MRI (fMRI) while they read a series of brief scenarios that described how the actions of a protagonist named John brought harm to either Steve or Mary.
