• The research, led by Dr. Miguel Maldonado, professor at the Metallurgical Engineering Department, intends to optimize this process through new on-line air measurement equipment.

During the last couple of years, we have heard about a decline in copper production, and according to experts this is one of the reasons why the quality of the mineral has been reduced. One way to revert this situation is improving mining procedures, which is a priority for mining industry.

One of these processes is flotation, a method used to separate valuable minerals like copper from others. The process starts once the rock is ground and mixed with water to form a pulp. Some reagents that modify the mineral surface are added to this mixture. In this way, when bubbles of air are forced up through the pulp, they collide with particles and the ones containing copper, for example, go up to the surface making a froth rich in valuable mineral, ready to be removed.

This is the method studied by Dr. Miguel Maldonado, professor at the Metallurgical Engineering Department. “Although today improvements have been made to flotation process- by means of devices that measure the air flow forced into a flotation equipment or the use of cameras that continuously monitor de physical properties of the froth- we still do not have a full knowledge of how air dispersion in the bubbles affects the metallurgical performance of the process,” the researcher said.

This encouraged the academic to do a research project called “Estimating on-line air concentration in flotation systems,” funded by the Scientific and Technological Research Department (Dicyt) of Universidad de Santiago.

“We believe that this variable is important when determining the process performance, as it is related to the surface area available to collect the particles containing valuable mineral and, therefore, to the complete recovery of copper,” the researcher explained.

The researcher said that the project was born while he was doing his postdoctoral research in Canada, at McGill University, considered a pioneer institution in proposing ways of measuring this variable. At that time, while he was studying this technique, he found out a problem with the interpretation of Maxwell’s equation, which would lead to a measurement error.

For this reason, the academic decided to insist on seeking new techniques in order to solve the problem; this time, with a better knowledge of the system.

At the first stage of the research, essential aspects of the error made will be studied. For this purpose, experiments to get a better understanding of the Maxwell’s equation will be performed. McGill University will also take part in this research by sending a flotation column to support the study and by developing papers together about this topic.

At the second stage, new techniques will be explored to find a method that estimates the air concentration in real time, in order to control and optimize the process.

In the academic’s opinion, “the efficient recovery of valuable minerals like copper is very important, and this measurement method could provide significant information for optimizing the process. This will have all kinds of benefits, such as reducing the reagents added or reducing the water used. This fact is also important if we consider that in most mining operations the water resource is scarce.”

• In order to meet the goals set by Universidad de Santiago in the context of the “Sustainable Campus” Clean Production Agreement, the University Social Responsibility program developed the first training workshop on this matter, oriented to students, academics and administrative staff.
• The initiative is one of the institutional actions to promote the knowledge on sustainability and to meet the goal of reducing the use of energy by 5% in the campus before March 2015, according to Santiago Peredo, RSU program’s alternate Director.
• The next workshop- on composting and vegetable gardens management- is scheduled for August. Also, the RSU program will hold seminars on the topics stemmed from the Institutional Sustainability Reports: human rights, decent work conditions, universal access to people with different skills, healthy eating and energy efficiency.

“People have become aware of environmental or sustainability matters. What we must manage now is to change some behaviors and develop some habits to be consistent with this already existing awareness,” Santiago Peredo, alternate Director of the University Social Responsibility (RSU, in Spanish) program said at the end of the first training workshop, “Self-diagnosis of energy use in buildings”, that was held by academics of Universidad de Santiago, on Friday 11th.

The workshop is part of the institutional actions to meet the goals set in the “Sustainable Campus” Clean Production Agreement (APL, in Spanish) of 2013, that seek to "promote training in this matter for professionals, students and academics of the University, and, in turn, to meet the goal of reducing the use of energy by 5% in the campus, before March 2015,” the RSU program’s alternate Director explained.

The workshop included two talks about energy efficiency. The first one was given by Professor Juan Araya, of the Bachillerato program, and the second one, by Professor Fernando Corvalán, of the Department of Geographical Engineering.

Professor Araya referred to the concept of sustainability in three interrelated aspects: environment, society and economy. The balance among the three of them becomes the sustainability equation. Professor Corvalán talked about energy efficiency in buildings, stressing the current actions taken in the building sector to save energy and the analysis of important supplementary aspects like heating, refrigeration and supply systems.

Regarding the campus, Dr. Corvalán explained that it was built according to standards that were not concerned for energy saving, such as the former EAO building and the buildings around the Planetarium. However, he emphasized that the new buildings mean an opportunity for energy sustainability.

Students, academics, professionals and administrative staff from the five units that voluntarily signed the University’s APL took part in the workshop: the Department of Geographical Engineering, the Technological Faculty, the Faculty of Administration and Economics, the Bachillerato program and the School of Architecture.

Waste management and vegetable gardens

“We prepared this series of workshops to meet the goals of training in sustainability and reducing the use of energy at the University, among others,” the RSU program’s alternate Director reiterated, as this is one of the actions established in the “Sustainable Campus” Clean Production Agreement.

The next workshop is scheduled for August and it will be about composting and vegetable gardens management, “because another goal is to reduce the solid waste produced at the University and this action could lead to new recycling processes that are not implemented now.”

“There are some initiatives to collect paper and glass in some recycling spots. We still have pending the organic waste treatment, as it is collected by an external service. The idea is that the University takes charge of the organic waste management and one way to do it is composting and the use of vegetable gardens,” Santiago Peredo added.

Pending tasks

Together with the sustainability workshops, the RSU program is planning continuous seminars that will include presentations and debates on five of the topics stemmed from the Institutional Sustainability Reports (2008-2012): human rights, decent work conditions, universal access to people with different skills, healthy eating and energy efficiency.

These five aspects are the ones that the reports have shown as weaknesses or needs. In these seminars open to the community that the RSU program plans to give every first Tuesday of the month (from August to December), the participants will evaluate the aspects that could be addressed in the workshops, according to the interests of the community.

• Diego Barría and Francisco Castañeda, professors at the Faculty of Administration and Economics of Universidad de Santiago, participated in a project of Jean Monnet Networks, an action co-funded by the European Union and led by the University of Milan.

   

  On June 25^th and 26^th, representatives of Europe, Asia and the Americas participated in the XIV European Workshop "Major Public Enterprises in a Global Perspective”, in Milan, Italy.

  Renowned international experts participated as speakers, like Massimo Florio of University of Milan; Lars-Erik Fredrickson (Chair OECD Working Party on State Ownership and Privatization Practices); and Richard Kozul-Wright, UNCTAD (United Nations Conference on Trade and Development) representative.

  Dr Francisco Castañeda, representative of Universidad de Santiago de Chile, said that the goal after this experience is to produce a working paper by September 2015 for CIRIEC-Belgium and University of Milan. “We agreed in publishing a paper in the Italian Journal of Public Economics by December 2015,” he added.

  Professors Barría and Castañeda gave a presentation during the conference and they said that corporate governance of state-owned enterprises has become a subject of great interest. “The OECD has been promoting best practices with regards to transparency, dissemination of information, election of public companies directors and the relation with stakeholders,” they said.

  According to these economists, indicators like financial performance, financial leverage levels, covenants, corporate bond issuance, and alternatives for getting resources to undertake new investment projects that allow sustainability in this type of company, should be evaluated.

  However, the "State-Owned Enterprises in the Market Place" OECD guidelines are more complex to implement in big state-owned companies.

  The Jean Monnet European Networks are made up of six universities:

  • Università degli Studi di Milano (leading University) – Italy

  • Ǻbo Akademi University School of Business and Economics – Finland

  • University of Greenwich – United Kingdom

  • Universität Leipzig – Germany

  • Université de Rouen – France

  • WU Wirtschaftuniversität – Austria

• The Academic Vice President, Fernanda Kri, said that after testing the pilot program in more than a thousand students of the Faculty of Engineering, the system that combines on-line learning opportunities with face-to-face sessions, proved to work in a similar way to a traditional course. “The goal is to implement this system for all our undergraduate programs in the first semester 2014, according to our Institutional Strategic Plan, which stipulates the promotion of the English language among our students,” Vice President Kri said.

In April this year, our University’s Academic Vice Presidency, together with the Consejo Superior de Docencia (the consulting body to the Academic Vice Presidency) and the Educational Innovation Unit started implementing an English language B-Learning pilot program for students of the Faculty of Engineering in order to evaluate the system’s operation and extend its application to other undergraduate programs of Universidad de Santiago.

The B-Learning method combines on-line content delivery with face-to-face sessions. It was implemented with the support of our University’s Department of Linguistics and Literature for one thousand and fifty students during one semester.

After concluding this first evaluation stage, the results proved to be very positive; hence, the academic authority started promoting its implementation in all undergraduate programs, according to one of the goals of the Institutional Strategic Plan, which stipulates the promotion of the English language among the students.

On November 27th, the Academic Vice President, Fernanda Kri, had a meeting with the academic community to inform about the results of this first B-Learning experience. She described it as “successful”, both logistically and academically.

“We confirmed that students who participated in B-Learning lessons acquired and English language knowledge similar to the one acquired in one semester of face-to-face sessions,” she said.

Due to this positive evaluation, the Academic Vice President invited all undergraduate programs to be part of the initiative.

“The purpose of the meeting (held on November 27th) was to show these results to the different faculties, hoping that most of them will join in this project and include it formally in the programs’ curricula as of March 2014,” she said.

“We expect all students at the University reach at least an intermediate level of English and for that to happen, they need to take four consecutive English courses, lasting one semester each, as this is the only way of having continuity in learning,” she added.

Vice President Kri concluded by saying that, besides the good results, “Students showed themselves very motivated for using technological tools and for learning English early in their programs. All this gives us good expectations about the contribution that this project may be to our community once it is extended to all undergraduate programs and, in the future, to graduate programs.”
 
The details about a successful program

Ricardo Úbeda, professor at the Department of Linguistics and Literature, who is in charge of the program, informed that out of one thousand and fifty students who took the B-Learning course, 182 passed the initial diagnostic test and were exempt from the final test, while 744 students totally passed the course.

Another announcement was the implementation of more mechanisms to allow the interaction between students and teachers, like Skype, that can help to solve questions in a direct way.

“Finally, with this course, all our expectations were met and we were able to see the high level of commitment that the students of our University have with their integral learning process,” professor Úbeda stressed during the presentation of the results of this B-Learning system.

• A security specialist at Universidad de Santiago will be the only representative of Latin America in the UN Advisory Board on Disarmament Matters, which is made up of sixteen international experts on this matters.

Dr Lucía Dammert, a security specialist at Universidad de Santiago de Chile, will be part of the UN Advisory Board on Disarmament Matters. Early in January 2017, Dr Dammert received an invitation extended by the UN Secretary-General, Ban Ki-moon to become part of the Board.

The Board has the goal of debating and commenting on the UN decisions on nuclear disarmament, cyber-attacks  and small arms and light weapons control and it is made up of 16 experts from all over the world. Professor Dammert, a Peruvian security specialist, will be the only representative of Latin America.

“Most of the Board members are experts on this matter or renowned academics,” Dr Dammert says. They come from Australia, Croatia, Jordan, USA, Philippines, China, South Korea, Spain, France, Mongolia, Pakistan, Russia, Ghana, Norway and Finland.

With regard to her participation, she says that she will contribute from the Latin American experience. “I expect to learn from the different realities in other parts of the world and, particularly, to identify topics which are not currently part of the security agenda in the country or Latin America,” she says.

The Board meets twice a year, in Geneva, Switzerland, and New York, USA. “During these meetings, the Board reviews different issues on the disarmament agenda and debates on new global challenges,” she explains. After the meetings, the Board delivers a report with suggestions and recommendations to the UN Secretary-General.

Dr Dammert is a sociologist, PhD in Political Sciences and professor at the Bachelor’s Program in International Studies of the Faculty of Humanities, Universidad de Santiago de Chile.

She has a vast academic experience at universities in USA, Argentina and Chile. Her participation in the Board is not limited to a specific period, as it is an “open invitation in time,” she says.

• The benefit of using geophysical techniques to recover historical remains was one of the main conclusions of the “Taller de Geofísica aplicada al Patrimonio Críptico Heredado.” “By using mining technologies, we want to bring our country’s historical riches out of the depths of the Earth, without impacting the environment,” Dr Lucio Cañete, one of the organizers, said.

On July 02^nd, the closing ceremony of the third “Taller de Geofísica aplicada al Patrimonio Críptico Heredado” was held at the Conference Room of the Technological Faculty. The workshop was led by the Dean of that Faculty, Gumercindo Vilca Cáceres and was attended by several university authorities.

The workshop gathered together almost one hundred men and women of different ages and from different professional areas.

The workshop was given in the context of the outreach activities developed by the Technological Faculty. This is the reason why “We emphasized that the participants should not be part of the university community: to have an impact at a society level,” Dr Lucio Cañete explained.

The workshop

According to Dr Cañete, the purpose of the workshop was to give basic knowledge of geophysics and its potential applications to a general audience interested in the inherited cryptical material, “that is to say, a paleontological or archaeological resource that it is not visible, that remains under ground, covered by vegetation or ice.”

“We referred to gravimetry, seismology, magnetometry and electrical resistivity, which are used to prospect for mining resources. Chile is very rich in these resources,” the researcher said, regarding the techniques addressed during the workshop.

However, the team of experts led by Dr Lucio Cañete learned that these techniques could mean a significant contribution to a different type of excavation: the digs for the past.

“Chile has hidden riches that we want to reveal through these techniques: the riches of our past,” Dr Cañete said.

According to him, our territory is rich in archaeological elements; for this reason, we need the tools to unearth the past without altering the ecosystem.

“Historical research has shown that the first settlements in our territory started 13 thousand years ago. The first remains of human settlements in the American continent were confirmed in Chile,” he said.

“We have a whole rich past that must be revealed, but this must be done with techniques that will not impact the heritage while we are trying to bring it out,” Dr Cañete stressed.

Digging is a very intrusive method; therefore, if it is used, “The destruction of the evidence of the past is highly probable. However, geophysical techniques use disturbances that allow “seeing without touching,” he added.

Geophysical techniques

Gravimetry measures the variation of the strength of a gravitational field; magnetometry measures how a magnetic field changes; seismology, by means of man-caused little microseisms, allows to see what is under the surface, and, finally, the electrical resistivity measures the changes in ground resistance when introducing an electric current into the subsurface.

Regardless of the surface, the use of these techniques “Produce a sort of disturbance that does not affect the part of the patrimony that we want to know,” Dr Cañete said.

In this regard, the main goal of the workshop was to understand these techniques and see how their use in the mining industry can be a real contribution to surveying archaeological, historical and paleontological remains.

“We saw this and, and in our role as a public and state university, we called for the development of all these techniques that, although they are traditional in mining industry, could be used in a new scientific field: the field of the sciences that study the past,” he added

“By using these mining technologies, we want to bring our country’s historical riches out of the depths of the Earth, without impacting the environment,” Dr Cañete concluded.

• Professor Osvaldo García was invited to give a presentation on an organizational self-observation tool, called CLEHES©, to postdoctoral students of Takashi Ikegami Laboratory, an institution specialized in the field of artificial life, at University of Tokyo.

More than ten years ago, Osvaldo García, professor at the Department of Industrial Engineering of Universidad de Santiago, started to develop CLEHES, a tool that intends the individual to generate learning, both at a personal level and at workl, through self-observation and the observation of interactions among human beings and their constituting networks, developing a diagnosis and an organizational design through Body, Language, Emotion, History, Eros and Silence (CLEHES©, its acronym in Spanish).

The contribution made by the course given by professor García, called Human Reengineering for Action (Rihpla, its acronym in Spanish), of the Department of Industrial Engineering, together with the academic prominence and prestige of CLEHES, made the publication of this innovative tool to be among the 100 most important international scientific publications in the field. In turn, it called the attention of different institutions that were interested in this emerging and effective technology.

For this reason, the professor Takashi Ikegami´s artificial life laboratory at the renowned University of Tokyo, in Japan, contacted professor García and invited him to give a presentation in September 2013 to graduate students at that Asian institution.

Professor García explained that, at Takashi Ikegami Laboratory, where the latest advances in robotics are being developed, they had a closed seminar for postdoctoral students and, besides, they explored the applications of CLEHES to the field of artificial life.”

“Students there made an effort to evaluate what changes could be made to apply some aspects of CLEHES´ structural dynamics to robot building,” García said. “We even talked about the possibility of generating a CLEHES-Robotics tool in collaboration with our University,” he added.

Professor García, an academic at Universidad de Santiago, stressed that, in Japan, robot building “is not approached through aggressive or merely recreational policies. It is considered a contribution to society, for example, to help senior citizens.” Therefore, the social self-observation tool CLEHES would be very useful.

Professor García showed himself satisfied with the new possibilities of internationalization and collaborative work with Japanese specialists opened by the research during the Rihpla course and CLEHES, and besides, he highlighted the concept of applied “ortho-discipline”, that is to say, to respect the autonomy of the different specialists involved in a collaborative project.

“In the Japanese culture, it takes time to establish collaborative relationships, but even so, we were able to forge significant links with them and also with the Japanese Embassy, where entrepreneurship and innovation are developing valuable bilateral ties,” professor García concluded.

CLEHES used by young researchers

Susana Gómez, who is doing her dissertation on diagnosis for her Master´s degree in Engineering Sciences using CLEHES technology, said that this innovative tool has been very useful to young students who pursue a specialization in management solutions.

“The networks created due to the international prominence of CLEHES have been amazing,” she said.

“This is a really new tool for management that is gaining strength and is being put into practice. Japanese specialists have the theoretical knowledge and the laboratories, but they have not put this technology into practice. Here in Chile, we have taken it to companies and schools and we have also applied it in our academic unit both in undergraduate and graduate students,” she said

For his part, Roberto Álvarez, a student who obtained his Master´s degree in Engineering Sciences by doing his dissertation using CLEHES to solve organizational problems said: “This management tool has been very helpful for my professional career and for working at big companies.”

“Besides, studying and applying this meta-discipline has helped us to open opportunities and to differentiate ourselves from other universities’ students,” he concluded.

• The projects supported by the Department of Agrarian Management of the Technological Faculty and the Food Science and Technology Research Center of Universidad de Santiago show important results, like a bio-pesticide based on residual quinoa grains or the potential edible use of this pseudo-cereal leaves.

The projects supported by the Department of Agrarian Management of the Technological Faculty and the Food Science and Technology Research Center of Universidad de Santiago (Cecta, in Spanish), show important progress in their goal of feeding the population in a healthy and equitable way.

The first project, “Biopesticidas en base a saponinas de quínoa” (Bio-pesticides based on quinoa saponins) (FIC 30343624-0) lasts three years and it is being developed in the O’Higgins Region, in Central Chile. It has the purpose of using the residual quinoa grains to generate a natural pesticide for grapevines.

The second project, “Valorización agroindustrial de subproductos de la quínoa” (Agro-industrial valuation of quinoa byproducts) (FIC 30429825-0), lasts three years and it is also being developed in the O’Higgins Region. The goal of this project is to promote the cultivation of quinoa, with new applications. Besides using the grains, they expect to promote the use of the leaves in salads.

The third project, “Habilitación de productores hortícolas de la región Metropolitana para la elaboración de productos IV gama” (Training vegetable producers of the Metropolitan Region in the elaboration of IV range products) (GORE BIP 30442786-0), lasts 18 months and it is the continuation of a project developed by the Cecta researchers in 2011 that tested different protocols to reduce the microbial load in vegetables like lettuces, cabbages and carrots.

Carlos Díaz Ramírez, Professor at the Department of Agrarian Management and Innovation Manager of the projects, explains that the purpose of this project is to train small farmers in the care and safety of all the production and supply chain of vegetables, until the products reach the consumer.

Some of the Cecta scientists involved in the projects are Professor Lina Yáñez Catalán, Dr Claudio Martínez and Dr José Luis Palacios Pino.

• Claudia Matus and Bárbara Ossandón, both professors at the Physics and Mathematics Teaching program of Universidad de Santiago de Chile, presented a novel initiative for the academic field at the International Educational Summit 2016: XII Conference on Higher Education Management.

Claudia Matus and Bárbara Ossandón, both professors at the Physics and Mathematics Teaching program of Universidad de Santiago, had a remarkable participation at the International Educational Summit 2016: XII Conference on Higher Education Management.

This activity has become one of the most important meetings for exchanging experiences at a management level among higher education institutions in Latin America, with the participation of renowned international experts.

The conference was held at the Casa Central of Pontificia Universidad Católica de Chile and professors Matus and Ossandón presented their work “Comunidad Práctica de Aprendizaje como elemento clave de gestión en el rediseño curricular de una carrera de pedagogía.”

“We designed a new innovative curriculum that based its pedagogical principles on a spiral modular design that involves the integration of theory and practice and is focused on the classroom activity and the student,” professor Ossandón explained.

She highlighted “the need of understanding curriculum management through an interdisciplinary team work and professional management. This means to strengthen the role of the head of the program and
distribute his/her tasks in four coordinations: practice, teaching, laboratories, and outreach and engagement. This last coordination has the purpose of providing feedback on the curriculum.”

“This interdisciplinary learning community that works collaboratively is made up of physics and mathematics teachers focused on didactics; an anthropologist, and other professionals,” she said. It is a group of committed people working in an environment where interdisciplinary collaborative work is usually understood as the sum of individual works,” she said.

“The strength of this initiative is the new design of the curriculum of the Physics and Mathematics Teaching program that allowed us to be accredited for seven years,” she added.

Conclusions

“What we want to share is the idea that, to achieve curriculum innovation, the line-up of collaborative interdisciplinary work teamsis very important in order to make the program management a profesional activity, as well as to encourage constant self-evaluation, what will result in constant improvement,” Professor Ossandón said.

The conference “helped us to validate the pedagogical principles of our program according to the different presentations given that addressed the latest trends in education that, in turn, allowed us to validate our own community, our team made up of the four coordinations. Besides, it enriched even more our pedagogical learning proposal,” she said.

“This activity is also an example of learning practice community,because on this occasion we learned about an education research network. This network is formed by universities in four continents and

it was created by the initiative of different communities, as the most advanced way of distributed leadership in the knowledge society, as Hargreaves said. This conference is a learning practice community
itself,” she added.

“We propose a professional, pro-active approach, where the head of the program can conduct research works with collaborative teams in the medium and long term,” she concluded.

• After four weeks of work in the Antarctica, Dr Raúl Cordero and Dr Alessandro Damiani, both researchers at the Department of Physics of Universidad de Santiago de Chile, were able to confirm that the extension of the hole in the ozone layer over the Antarctica reached more than 10 million km² in December 2015, i.e. more than twice the average of that period in the past three decades.

​

The measurements were carried out during a campaign in the Antarctic Circle in the context of the Antarctic Scientific Expedition of the Chilean Antarctic Institute (Inach, in Spanish). Dr Raúl Cordero and Dr Alessandro Damiani, both professors at Universidad de Santiago de Chile, were part of the expedition.

The ozone measurement campaign at the Antarctica started on November 15^th and it continued until mid-December. Four researchers at Universidad de Santiago travelled to the heart of the White Continent, where about 600 kg of the best radiometric equipment available were sent.

The expedition was supported by Inach, what allowed the researchers to work at “Unión Glacier” Joint Polar Research Station located at 79 degrees South latitude, at about 1000 from the South Pole.

Constant monitoring

In spite of the negative results of this year, Dr Cordero expects that a process to recover the ozone layer starts in the short term, as a result of the actions taken worldwide to reduce the emissions of polluting gases. However, the information gathered highlights the need of adopting mitigation policies and conducting a constant monitoring of the area.

According to Dr Cordero, “the ozone layer depletion is mainly caused by the presence of ‘ozone destroying” chemicals in the polar stratosphere. These substances are generated by the industrial activity in mid-latitudes.”

Although these substances are everywhere in the planet, high latitudes are the most impacted areas by the layer depletion or destruction, particularly the Antarctica. During the southern spring, this area is affected by a massive destruction of the stratospheric ozone as a result of the particular weather conditions there.

According to the researcher, the ozone depletion process between September and December is favored by the low temperatures in the Antarctic stratosphere and by the Antarctic polar vortex that prevents the ozone from other latitudes from closing the hole.

“When temperatures increase at the end of spring, the ozone massive depletion stops and the weakening of the polar vortex allows the ozone from other latitudes to close the hole. The bad records this year are probably the result of unusually low stratospheric temperatures during last spring,” Dr Cordero said.

Recovery of the ozone layer

In spite of the negative results of this year, Dr Cordero expects that a process to recover the ozone layer continues until the middle of this century due to the actions taken worldwide to reduce the emissions of polluting gases. However, the information gathered highlights the need of adopting mitigation policies and conducting a constant monitoring of the area.

It is also worth to mention that this study included comparisons with databases of other months. According to this, the hole in the ozone layer reached 28 million km² in October, the fourth highest record since the satellite data is available. 

Dr Cordero also highlights the relation between ozone depletion and climate change. “The changes in the hole in the ozone layer could affect the energy balance of the Antarctica. Ozone depletion or exhaustion has affected the temperature of the stratosphere and it correlates with wind and surface temperature variations detected in the Antarctica in the past decades. Therefore, a better understanding of the relation between climate change and the hole in the ozone layer is required. This is the ultimate goal of our work,” he concluded.
