Agricultural crops are permanently exposed to infections caused by dangerous phytopathogenic agents, which can seriously damage plants and even cause losses of vegetable crops. 

One of the most harmful phytopathogenic bacteria for agriculture is the species Pseudomonas syringae, which affects kiwifruit, cherry, plum, tomato and bean plantations, among others. As a result of this infection, there are considerable losses in production and harvests, implying millions of dollars in economic losses for the industry.

Audiological diseases due to continuous exposure to noise at work are among the main occupational pathologies in our country, according to data from the Superintendence of Social Security.

The WHO recommends a limit of 65 decibels to ensure good health and well-being of people, while Chilean regulations allow up to 85 decibels in eight-hour workdays, which is not always complied with.

Chile is one of the leaders in the world salmon industry, occupying second place in salmonid production, after Norway, and supplying 25% of the global supply. At the national level, this product is the largest exporter, after copper.

The sector faces several challenges, however, including the spread of diseases that threaten the stability and quality of production. One of the most common and dangerous is salmonid rickettsial septicemia (SRS), caused by the bacterium Piscirickettsia salmonis.

Burner or ignition systems are essential for the operation of industries such as pharmaceuticals, food and energy, as they facilitate the ignition of fuels to generate heat, energy or perform key processes. Their use in mining, manufacturing, construction and transportation, among others, ensures the continuity of operations. 

Chile is one of the world leaders in the aquaculture industry, positioning itself among the main producers of species such as Atlantic salmon and rainbow trout, which are highly demanded in international markets. However, for the industry to be able to guarantee productivity and competitiveness at a global level, it must meet high standards of health and breeding of salmonids. It is therefore essential to prevent and treat viral infections that affect the health of the fish, which jeopardize the stability and quality of production.

In order to identify new opportunities for joint work in research and development (R&D) projects, the Directorate of Technological Management (DGT) of the Vice Rector's Office for Research, Innovation and Creation (Vriic) organized a meeting that brought together researchers from the University of Santiago de Chile and executives from the technology company CoreDevX.

PET is a fully recyclable plastic, which can be processed after use and converted into rPET (recycled PET) to manufacture new products. However, in Chile less than 15% of PET reaches recycling plants to be transformed into rPET, says a report by the Chilean Plastics Industry Association (Asipla). This is clearly illustrated by the low household recycling rate of plastic bottles, which barely reaches 7%.

PowerPoint is one of the most widely used tools to design effective presentations that help communicate ideas and generate audience interest. However, these objectives are not always achieved.

Progress has been made in this technology at our University, thanks to iSlidesRC, a set of software components compiled as an add-in for PowerPoint, which allows the creation of interactive and editable slides during the projection of the presentation. The audience can also participate by editing the slides from their mobile devices.
