 Scope 

Our main research line is determination of complex type N-glycans in plant fluids, called to detect early nutrient deficiencies and/or crop diseases. We support and develop novel hardware and software solutions for solving analytical challenges in a sustainable manner.

N-linked protein glycosylation in plant science is important, considering that it can modify most biological functions of proteins, and affect development of all living organisms. Although, the knowledge of N-glycol biosynthesis and processing is continuously improving, there is still a limited number of studies that examine biological functions of N-glycan structures in plants. 

 

For this reason, investigating PCT-FNGs distribution in crops is significant toward discovering new indicators of biological processes in growing plants, thereby contributing to sustainable agriculture practices.

 

Given that in present N-glycan databases (e.g., glycostore.org) comprise exclusively human profiles, we intend to initiate an international collaboration in which researchers all around the world we realize an Open Access database for plant PCT-FNGs profiles before year ending. 

 

Technology

 

For separation we primarily use a self-designed miniaturized CE (Capillary Electrophoresis) device. Please, find detailed information on the system components and measurement procedures below:

1. Detection (Imaging Laser-Induced Fluorescence, iLIF): (1) image acquisition-based detection with “spyglass” design (monocular lens ∼3 cm away from the detection zone) setting the target in the center of the view field; 405 nm diode laser (5.0 mW, Laserland, Wuhan, PRC) installed to illuminate the detection target zone; 12.5 mm diameter EO520/10 emission filter (Yulong Optics Co, Ltd., Kunming, PRC). Collected and bandpass-filtered light reaches an 8-megapixel CCD camera (Pi NoIR Sony IMX219, Tokyo, Japan) 

2. Image Processing ARM cortex Raspberry Pi-3b minicomputer serves as the image processing unit, which runs on a Raspbian for Raspberry Pi operating system (Cambridge, U.K.); image processing-based detection is performed in python scripts, in time-lapse mode (Raspistill library, Raspberry Pi)

 

3. Results (Gu values) are compared to CE database in Glycostore (https://glycostore.org). 

 

Justification of current setup

 

Capillary electrophoresis (CE) is among the best resolving liquid separation techniques, which still benefits from miniaturization. Analytes are separated by their hydrodynamic volume to charge ratio. CE can be rated as a sustainable technique in the field of liquid phase separation science, owing to its minimal mass/volume/energy requirements.

For rapid plant health assessment, we usually apply hyperspectral imaging techniques (e.g., N-deficiency calculated from % chlorophyll content) using Parrot Sequoia Multispectral Sensor (Parrot, Inc. France) and Qgis 3.4 software to interpret the images.

 

In the near future we will report results obtained with an ecologically convenient CE system. For storing and maintaining Glycan Retention Properties of plants we are creating GlycoPlants™ 

Collaborative international projects

We do and support research in a variety of disciplines, including: Medicine, Planetary Health, Environmental Engineering, Information Technology, Database development, Sustainable Agriculture, EcologyBiochemistry, Genetics and Molecular Biology, Immunology and Microbiology, Economics, Entrepreneurial management, Startup Mentoring.

Microbial biomass carbon (MBC) and soil organic carbon (SOC)

MBC and SOC are well established and widely accepted microbial quotients in soil science. Our approach should contribute to the better understanding of MBC and SOC distribution in soil and changes in MBC/SOC at various altitudes in the Ecuadorian Amazonian region.

Soil quality

We examine how different altitudes impact the pH and total iron content in Amazonian Andes, Ecuador. We found that total iron content significantly decreases (R2=0.966) at lower altitudes. For future studies, the authors recommend that along with Fe ion content one should determine calcium, microbial biomass, and microbial activity to better understand iron mobility and dynamics of iron uptake in the area.

Egg quality

An economically active population refers to people involved in any economic activity, such as agriculture, livestock, or industry. We analyse the egg quality in Andean communities using a random sample of hens and eggs obtained from more than sixty producers, belonging to 50 farming families at the Utopia Community Fair. In addition we perform zoometric characterization of the hens using FAO protocols. We calculate profit/cost indicators as well as we determine the ratio of expenditure (egress) and total revenue of egg sales to improve the economy of the local communities. 

Reserve batteries

a calculation for energy density 

The “urban century” has arrived in which we have to address a broad suite of sustainability challenges in both urban  and rural areas. The need for electricity generation is continuously increasing in modern  societies.  One  main  goal  of  global  energy sustainability is to replace the fossil fuel- based energy by renewable energy and reduce emissionsRecently,  battery  storage  has  been emphasized  as  an  effective  way  to  increase  share  of renewables in photovoltaic energy systems utilized in farming. Here we address reserve batteries or deferred-action batteries, which are primary cells intended for emergency use.

Startup mentoring

Presently knowledge represents a major factor for the development of a country’s economy. For rendering Ecuadorian startups more profitable one should consider three criteria that enable successful innovations, namely the idea must be desirable, viable, and feasible. Our results represent original contribution to the quantitative evaluation of the real value of a given startup company, allowing the innovation-based ranking of startup companies according to the extent of their innovativeness.

 

Comparison of Bio and Chemical fertilizers

We compare biofertilizer, commercial NPK fertilizer applications (in four doses: N60P45K45;N120P90K90;N180P135K135; and N240P180K180), and two different cultivation methods (ploughed, loosened, RTK in rows, and RTK between rows)

* correspondence: danimtalledo4282@utm.edu.ec

The present investigation was carried out in a Fluventic Haplustepts soil in the Chone canton, province of Manabí. The objective of this study was to analyze the physicochemical properties of the soil and its association with organic matter in a productive system of tropical pastures (Brachiaria decumbens and Panicum maximum). The variation coefficient (VC) was calculated for the results obtained, and the resulting variables were subjected to a Principal Components Analysis (PCA). The results obtained showed that 73.92% of the total variability was explained by the variables MOS, C, CIC, Da, CC, PMP, pH, DSD, P, Zn, Ca, Mg, K, in addition the content was evaluated from MOS to 0.20m and soil moisture. This investigation allowed us to conclude that organic matter directly influences the variables C, N, DSD and CIC and inversely on properties such as P, Zn, Ca, K, pH, Mg, Da, CC and PMP.

As of today, biomimicry merely imitates isolated features of biological structures, but neglects the actual physical processes that govern the system. Biomimetic design delivers only sub-optimal results as it often does not consider that constraints in technological applications are different from biological systems, or that a natural structure might not be optimal under all conditions. Natural selection has been “optimized” over billions of years yielding system designs that can serve as source of inspiration to scientists, enabling efficient energy generation, energy conversion, and electrochemical energy storage. In this undertaking, natural models allow the development of improved porous electrodes and transport system, so-called “hierarchical” structures, which are efficient, robust, and scale up easily. To obtain improved efficiency of energy conversion devices, deterministic design of electrodes should be used instead of random packing of components into the electrode material. Biological blueprints also serve for surface designs. Use of biomass represents an approach to sustainable energy conversion in the framework of green strategy.

At present, there are no reliable criteria regarding the quantity of nitrogen fertilizer to apply in pasture soils, therefore, it is important to improve the efficiency of nitrogen (N) fertilizer use in practice. We believe that it is necessary to identify a fast and reliable soil N test procedure for predicting mineralizable N (Nm), for soils cultivated with tropical grasses. The objective of this research was to evaluate the indicators of N mineralization by Walkley-Black (WB), Illinois Soil Nitrogen Test (ISNT) and Direct Steam Distillation (DSD) in 35 farms cultivated with tropical pastures at a depth of 0.20m, from an area of ​​0.40ha. Next, correlations between variables were developed to establish the possible relationships between the physical properties studied and the Nm predictors. As well as to obtain the recovery percentage and correction factor of WB, ISNT and DSD. All statistical analyzes were performed with the R Core software, 2018. It was determined that ISNT and DSD were significantly correlated with each other (R2 = 0.92), while WB with DSD did so with (R2 = 0.94). The results show that higher Nm was estimated by ISNT and DSD than by WB, and that its content was different depending on the apparent soil density and the level of soil organic matter (MOS) as soil parameters. The methodology that best correlated with the WB indicator was DSD, so we concluded that this indicator is an effective predictor tool of nitrogen fertilization to achieve agronomic and environmental sustainability of livestock farms in tropical Ecuador.

* correspondence: mriverac@unam.edu.pe 

Queñoa forests are the most impacted ecosystem by antrophogenics activities in Los Andes. To gather information about current status is necessary to plan both management and reforestation programs. The objective of this study was to evaluate the population composition, associated flora, phenology and their relationships with anthropic factors, as well as the population density associated with Muylaque forest, district of San Cristóbal. The study was carried out from January to December 2016. Thirteen plots of 500 m2 were sampled. A population census was conducted in each of the sample units. The population structure shows predominance of latizales with 239 individuals, followed by adults with 217 individuals and in smaller quantity the saplings with 164 individuals. The average of individuals per plot was higher for the latizales (average ± standard error: 18.4 ± 3.6) followed by adults (16.7 ± 4.3) and saplings (12.6 ± 4.5), respectively. It is estimated that the density of adult individuals is equivalent to 333.8 individuals/ha. Polylepis rugulosa yields floral buds during the wet season (December to March), while in the dry season (July to September) individuals in a vegetative state predominate. The fruiting state predominates between February and April. The principal affectation in adult specimens is the logging, plagues and drought, in the latizales and saplings the overgrazing and environmental factors. The associated flora is composed of 72 species of herbaceous and shrubby plants distributed in 28 families.

* correspondence: aportiz1@utpl.edu.ec 

The mechanical properties of concrete specimens made from recycled particles are displayed instead of percentages of natural aggregates. Recycled rubber and plastic particles obtained from the companies ECSADE S.A. were used. and Juan Álvarez located in the Ecuadorian cities Guayaquil and Cuenca respectively; as well as aggregates of the Arias quarry in the city of Catamayo, 37 km away from the city of Loja. The 21 MPa compressive strength concrete design was performed using the ACI design method. Once the concrete has been manufactured with proportions of 0%, 5%, 10% and 15% of recycled particles in substitution of the fine aggregate, it is subjected to curing submerged in water 28 days, then to compression and bending tests, determining that at replacing 5% of fine aggregate with plastic particles is obtained in the specimens compressive strength of 20.24 MPa, flexural strength of 3.93 MPa and a density of 2394.33 Kg / m3; These results, when compared to the model developed without the addition of aggregates, allow us to define that there is a 2.07% density reduction, 9.36% reduction in compressive strength and 2.24% decrease in flexural strength. These results, when compared to the model developed without the addition of aggregates, allow us to define that there is a 2.07% density reduction, 9.36% reduction in compressive strength and 2.24% decrease in flexural strength.

* correspondence: jesus.melendez@cu.ucsg.edu.ec   

In the global context, we are in the presence of a growing demand for energy. The use of biomass is considered a viable alternative for the production of biofuels. Thus, the production of ethanol of first (1G) and second-generation (2G) represents a sustainable alternative with the environment compared to the production of fossil fuels. However, the economic feasibility formed by the evaluation of costs and efficiencies determines the production of biofuels. The objective of this study was to determine the key factors that should be considered in the managerial context for the production of biofuels, in the cases of ethanol (1G) – (2G). The methodology follows the guidelines of a systemic process of evaluation and analysis of the information. The contents present the existing gaps that determine the selection of sustainable production methods for agro-industrial organizations from the managerial and decision-making context. The results show a complex scenario defined by the economic valuation versus the efficiency of the production process determines the production of biofuels and the selection of the technology applied. The future expectations of the business management process related to the production of biofuels focuses on the use of raw materials of cellulosic origin as a sustainable alternative for countries that do not want to compromise food (sugar cane). It is concluded that the industrial management for the selection and production of the first or second-generation biofuel will depend on the decisions focused on the adoption of cost-efficient technology versus high yields and with low environmental impact.

In the approach to environmental issues at global, national and local levels, current trends show the deep environmental crisis, expressed to ecosystem level, in the depletion of resources and supplies for the production, the deterioration in the quality of life among others. To face the environmental crisis, it is necessary to keep in mind the approaches of UNESCO, AGENDA 21, OECD and the Millennium Goals. Environmental education in Peru’s education system highlights the need for a new profile of teachers, trained to tackle environmental issues with the student ́s participation, parents and community. 75% of teachers indicate that the student is not environmentally trained to express their practice in the community; 100% of them affirm that with the application of environmental strategies positive results in the environmental training of students would be obtained. This research entails how to do the pedagogical practice by articulating it with the instructive, educational and developmental dimensions in order to commit the student to the conservation and the natural and social transformation. The purpose was to design a theoretical model of environmental training, which constitutes a proposal for the elaboration of environmental strategies student ́s basic education, taking into account the participatory method of the environmental training process actors, subjects of the process and the components of the same process. The relationship between the theoretical model and the practice is established through a program of environmental strategies.

* correspondence: dgandarillase@unjbg.edu.pe

The objective of the study was to determine the biometric characteristics of alpaca’s herds at high Andean zone of Tacna. This study was carried out in alpaqueras communities of Huaytire and Maure; located in the high Andean zone of Tacna region. Morphometric measurements were made of 114 alpacas (55 from Huaytire and 59 from Maure). The measures considered were: Live weight (PV), Thoracic perimeter (PT), Body length (LP) Head length (LC), forehead width (AC), height at the withers (AX), Height at rump (AG), rump width (AcG). An analysis of variance was used to determine if there is influence of the community, sex and age on the variables studied. For the comparison of means, Duncan test was used. The results indicate that there are statistical differences (P <0.05) in the zoometric variables. The community of Huaytire shows higher weights (47.70 ± 1.19) compared to those of the community of Maure (38.87 ± 1.19). The thoracic perimeter of the animals of Huaytire is greater than those of Maure (98.41 ± 0.93 vs 87.47 ± 1.09). In conclusion, the alpacas of the community of Huaytire present greater weights and biometrically different in relation to the community of Maure.

Agricultural intensification is essential to satisfy the global demand for food, but this threat to native species and degrades ecosystems. Sustainable intensification was announced as a new approach to allow growth in agriculture minimizing the negative impact on the environment. The Sustainable Development Goals (SDGs) have brought the needs of the world population to 2030 in mind, including the agricultural sector offering key solutions for development, which are vital for the elimination of hunger and poverty, allowing access to clean water and sanitation, health and well-being, taking urgent measures to combat climate change and its effects, sustainably managing forests while combating desertification, stopping and reversing land degradation along with detention in The loss of biodiversity. This creates great challenges for agriculture and encourages to reduce the yield gaps that exist at the moment, but in the same way there are forces against it, the market and some protectionist actions put these global challenges in check, so it is necessary have a general concept of yield gaps and potential crop yields, so that everyone speaks in the same direction and lowers the same variables that are comparable at different spatial points on the planet. It is recommended to use the modified performance gap fraction and make interventions in reducing the gaps where it is further away from 0 (zero).

In the last decades the development of nanotechnology applications has generated that products such as silver nanoparticles (NP Ag) have a great demand, generating that the scientific community continues to study friendly ways and of low toxicity with the environment and health. In this context, this review was developed in which the economic valuation of the reuse of agro-industrial waste, specifically grape marc, is analyzed. The productive capacity is analyzed considering fixed and variable costs between the standard NP Ag colloid (50 mL / 30 nm), the NP Ag colloids obtained by typical synthesis using sodium citrate as a reducer (50 mL / 20-40 nm) , and the green chemistry method as a sustainable alternative (50 mL / 30-40 nm) by using the grape extract obtained from wine residues. The review criteria using the sensitivity analysis methodology focused on the environmental impact of the two techniques compared, as well as their productivity, procedures, energy consumption and economic factors present in the processes. Regarding the NP Ag colloids, the results by UV-vis spectrophotometry show that the green chemistry method using alcoholic grape residue extract allows to obtain silver colloids (NP Ag) with an approximate size between 30–40 nm with high monodispersity and stable, which are identical to the standard, and on the contrary in the case of citrate they are not usually so monodispersed. The costs of green synthesis reduce the price of colloid compared to the standard, in addition to reducing the impact of indirect chemical contamination. Based on the analysis developed, availability and an opportunity to give added value to the residual material of the wine industry are also suggested, contributing to the sustainability of the agribusiness chains.

The Normal, Heavy and Massive Concrete Mix Design Method, ACI 211.1, allows us to calculate the proportions of the constituent materials of a concrete mix for a specified compressive strength, f’c, given. Current Artificial Intelligence techniques require a large direct database of thousands of records; therefore, researchers create databases on concrete mix designs; however, more often than not, these databases have at most a hundred records; however, it is known that the more data you have, the better the results of the Data Modeling or Artificial Intelligence techniques; so this work aims to develop a method for creating a data set of concrete mixes with the number of records required. It is developed from ACI 211.1 tables and nomograms, which are integrated with the interpolation-extrapolation algorithms. As a case of use, two databases are created with 1344 and 11712 records respectively, which is validated with laboratory results from other research. It is concluded that using the techniques of interpolation and extrapolation the tables of the ACI 211.1 can be automated, that create a database of concrete mixtures, which can have diverse uses.

The outstanding features of ethanol fuel and its consumption in many countries such as Brazil, Mexico, Colombia, Venezuela, Ecuador, EEUU among other European countries that use as renewal energy in spark-ignition engines attract the attention of many countries researchers all over the world. This paper presents a considerable literature review of the most important operating characteristics in spark-ignition engines that use blends of ethanol and another interesting technique in bivalent motors that employs ethanol direct injection and gasoline port injection.
The influence of ethanol on thermal efficiency, brake mean effective pressure, brake specific fuel consumption and volumetric efficiency are discussed. In addition, concepts like ethanol energy ratio and mass fraction burned are introduced in the present study as well as an overview of the consequences of ethanol on hydrocarbon, carbon monoxide, nitric oxide, and nitrogen dioxide gas emissions.
Gas emission analysis indicates variable results depending on the way ethanol is injected into the combustion chamber. A decrease in hydrocarbon and carbon oxide emissions are common whether ethanol blends are used; nevertheless, ethanol direct injection presents the opposite results. Additionally, nitric oxide and nitrogen dioxide gas emissions vary tremendously among studies. Some studies report a decrease in gas emissions while others the other way around.
