• 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.

• Through a Fondecyt Initiation into Research Project, Dr. Luis Lemus, professor at the Faculty of Chemistry and Biology, has studied the interaction between new molecules called “helicates” and DNA, in order to evaluate the development of more specific drugs to fight cancer, avoiding the destructive effects of chemotherapy and radiotherapy.

According to Globocan, a worldwide survey on cancer conducted in 2012; there are 14.1 million new cases of this disease. At present, the most widely used treatments are chemotherapy and radiotherapy. Their purpose is to stop cancer spreading in the body by killing malignant cells that divide rapidly, one of the main properties of most cancer cells; however, in the process healthy cells are killed too: hair follicles, gastric mucosal cells, blood cells, etc. These side effects make these non-specific treatments very destructive:

Something that could help to change this situation is the development of new compounds with a higher selectivity towards a specific biological target, the line of research of Dr. Luis Lemus, professor at the Faculty of Chemistry and Biology of Universidad de Santiago, who leads the Fondecyt* Initiation into Research Project named “Study on Helicates as DNA coordinators”. Its results could lead to developing more specific anticancer drugs.

“These molecules (helicates) are able to bind to DNA strands by means of specific and strong interactions, modifying its structure, what prevents the genetic material from replicating inside the cell. What should be noticed is that cancer cells are the ones that produce the largest amount of DNA; therefore, these molecules could be a potential treatment against cancer progression,” professor Lemus stresses.

To make progress in the treatment of this disease, first it is essential to deepen the knowledge about these compounds, which started to be studied less than 30 years ago. According to professor Lemus, nowadays there are a few groups in the world dedicated to study the use of helicates as anticancer drugs and the way in which this type of interaction affects the DNA structural modification has not been studied yet. This is the line of research that Dr. Lemus intends to develop.

“Helicates are inorganic chiral molecules with a helical shape similar to the one of DNA, in which each molecule has a helical twist sense defined according to its structure. These positive molecules interact with negatives ones, in this case, DNA. After this electrostatic attraction occurs, the DNA is able to recognize and selectively establish secondary interactions with helicates with better twist sense than others. Here, documenting this phenomenon is essential.

This project will be implemented in two stages. First, by performing the structural study and synthesis of different types of helicates with different transition metals; and second, by doing DNA tests to evaluate the affinity between the molecules and DNA, and the extent to which helicates could modify the latter.

Regarding the projections of the study, professor Lemus says that in the future, “it would be ideal to evaluate these compounds against cancer cells and therefore, to prove if they are able to kill these cells. However, today we are trying to build a very basic knowledge, because it does not exist. Acquiring this knowledge will be very helpful for us and for other groups.”

A field to explore

Creating a research group dedicated to study inorganic complexes for biological applications is among the goals that Dr. Lemus has for this project. According to the academic, this area is little developed in Chile, so this study could start a new line of research both at the University and in the country.

“We have the facilities, equipment and experience in synthesis to meet the initial goals of this project; but we also need help from other researchers who could contribute with their knowledge in biology to make the study more valuable. This project is the first step for the expectations that we have as a group,” Dr. Lemus says.

• 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.

• Dr Leonor Huerta, physics engineer, Master’s in Astronomy and professor at Universidad de Santiago, says that the discovery of a new solar system with Earth-like planets should promote the creation of more research centers and the generation of more resources to take advantage of the astronomical potential of our country.

Scientists at the NASA informed about the discovery of a new solar system with seven exoplanets similar to the Earth in size and temperature. The system, Trappist-1, is about 40 light years from Earth and it contains three planets that are likely to be habitable, as their weather conditions would allow liquid water, and maybe, life. The telescopes in La Silla and Paranal observatories, both located in the north of Chile, took part in the discovery. 

Dr Leonor Huerta, physics engineer, Master’s in Astronomy and professor at Universidad de Santiago, said: “We need more astronomy and research centers to incorporate all the human capital generated in Chile. We have facilities available at no charge, as large foreign conglomerates have built telescopes in Chile for the quality of its night sky in the north.”

“We need more Chilean scientists to work on this, not only astronomers. If we are going to search for life in the universe, we also need astrobiologists and geologists,” she explained.

“Observatories also require “Hydraulic engineers and computer scientists, for example, to take care of the infrastructure. This is a multidisciplinary field. To explore the universe and to study the evolution of life, we will need a very strong multidisciplinary collaboration,” she added.

“From a scientific point of view, this finding is very interesting because there are three planets which are likely to have water somewhere on their surface in its three states: solid, liquid and gas.”

With regard to the next stage after this finding, she said: “Clearly, the next step is to know if these planets have atmospheres. This will happen when the next exoplanet program mission of the NASA is carried out.”

Although she recognizes that it is very likely that there is other life in universe, there is not any empirical evidence. “For a scientist- astronomer or biologist- it is very difficult to affirm that the conditions of our solar system are unique,” she says.

• Dr Laura Almendares Calderón, professor at the Technological Faculty of Universidad de Santiago, presented her study “Development of a technology to replace prickly pear skin with a peel to keep the physiological, microbiological and organoleptic properties of the fresh fruit” at the Expo Milano 2015 (Italy). Dr Almendares presented the innovation in an activity devoted to the best sustainable development practices for food security.

Dr Laura Almendares Calderón, professor at the Technological Faculty of our University, carried out a technical visit to the Expo Milano 2015 (Italy) in order to get an insight of the food situation around the world. She was able to see a wide variety of raw materials, manufactured goods, equipment and supplies exhibited by more than one hundred countries. The activity had the presence of leaders from all over the world, like President Michelle Bachelet, who opened the Chilean Pavillion.

In this context, Dr Almendares, director of the FIA-USACH Project, PYT-2012-0033, “Development of a technology to replace prickly pear skin with a peel to keep the physiological, microbiological and organoleptic properties of the fresh fruit”, presented her work at the BSDP Week.

The activity started with an exhibition of photos, porters, brochures and other information material related to this matter. The academic was able to show the results of this Chilean innovative project to people from different countries, at the Urban Center, Galleria Vittorio Emanuele, in downtown Milano, between June 10^th and 13^th.

Chile participated in the competition “Feeding Knowledge”, a program created to contribute to the permanent legacy of the Expo Milano 2015.

With that purpose in mind, a document will be generated containing policies and key recommendations to create an effective knowledge system in the food security field in the Mediterranean Region. The final version of this document will be available in September this year.

Selection of proposals

The proposals submitted by eligible candidates underwent a strict admission control by the International Selection Committee, which is responsible for the final evaluation, using nine pre-established criteria.

The proposals that did not meet one or more of the admission criteria were not considered as “Good Practices in Food Safety.”

The ones that were well evaluated officially became “participating initiatives”, like the work presented by Dr Almendares. 

Her work was included in the priority theme “Food consumption habits: diet, environment, society, economy and health.”

This theme groups all projects which objectives are focused on research activities that evaluate the impact of current diets on the environment, economy, society, culture, health and nutritional sustainability.

This was the only Chilean study presented at the activity and it was registered as ‘9712. Development of methodology to replace prickly pear skin for enriched eatable peel. Chile. 25’.

• 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.

• 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.
