Background and aims: Zephyranthes tubispatha is a South American species with ornamental and pharmacological potential. We aimed to study: 1) attributes of fruits, seeds, seed-seedling transition substages, normal and abnormal seedlings; 2) germination due to the effect of different storage periods, seeding times, and exposure to supra-optimal temperatures; and 3) plant vigor. M&M: Samples harvested between 2018 and 2022 (Buenos Aires, Argentina) were used. Fruits and seeds were characterized morphometrically and seminal reserves histochemically. Substages during the seed-seedling transition were defined, and normal and abnormal seedlings were morphologically described. The germination of seeds from different storage periods, seeding times, and thermal conditions was evaluated. Changes in seed viability, electrolyte loss, and plant vigor were studied. Results: In the seeds, lipids and proteins were detected as reserves. Normal and abnormal seedlings and the seed-seedling transition with five substages were described. Seeds of up to 10 months of storage, different seeding times and thermal conditions presented high germination percentages. High temperatures thermoinhibited germination, but did not affect subsequent plant survival. Conclusions: Storage for more than one year showed increased seed mortality and seedling anomalies. The seeding moment conditioned the germination response to the heat treatments, and thermoinhibition did not affect the vigor of the plants produced. [ABSTRACT FROM AUTHOR]

The different agricultural practices on the soil affect its capacity to capture and store organic carbon (CO), causing greenhouse gas (GHG) emissions that influence climate change. The aim of this research was to evaluate carbon storage in soils of 16 livestock systems in the municipality of Guatavita, department of Cundinamarca, Colombia. Four groups were defined: 1. Systems with Modern Technology (ES: SPTM), 2. Medium Productivity Systems (ES: SPMP), 3. Traditional Systems (ES: SPT), and 4. Eco-friendly systems (ES: SPEA), according to the type of environmental supply and technologies used in the above-mentioned systems. We determined the carbon storage by calculating the percentage of organic carbon (% CO) using the Walkley & Black method; by evaluating the bulk density (ES: DA) through a paraffinized clod and the depth of the soil sample taken with a helicoidal auger. The results showed statistical differences (p > 0.05) for the variables % CO and DA between some groups, but not for carbon storage. We found that group 4 presented a storage of 179.18 tons of carbon/hectare (tC/ha), followed by group 2 with 170.48 tC/ha, group 1 with 137 tC/ha, and group 3 with 135.07 tC/ha. The DA values of all the systems ranged from medium to high despite this condition and its relationship with the CO content; it is concluded that Guatavita livestock systems are ample fixers of atmospheric carbon in soils and contribute to mitigating the harmful effects of global climate change. *ES: conventions with Spanish abbreviations.

Introduction: In the next sugarcane harvest only 23 mills will grind to produce sugar. The rest must look for alternatives to generate income. Some are going to produce molasses, from leftover cane, as raw material for their own distilleries or to sell to others. This may imply, depending on the capacities of the facilities and transportation possibilities, storing the molasses. This, when stored for long periods with high concentrations of sucrose, tends to divide into syrup rich in reducing sugars and crystallized sucrose, so its hydrolysis is required to avoid deterioration. Objective: To obtain the best operating conditions for the investment of the molasses using the thermostable invertase enzyme GS115BfrA4X Pichia pastoris as a catalyst, produced at the UEB Bioprocesses Cuba 10. Materials and Methods: To establish a relationship between the enzyme concentration (U/g of molasses) and the molasses concentration (°Bx) on the percentage of sucrose conversion, a 2² factorial design plus a central point and a replica of the matrix of design was carried out, using the Statgraphics Centurion XVI. Results and Discussion: The best experimental result obtained was a molasses concentration at 55 °Bx, an enzyme concentration at 15 U/g of molasses to achieve a 76% conversion in 5 h of reaction. Conclusions: From the multiple regression model, from the best experimental results, it was obtained that at concentrations of 57 °Bx molasses, 11 U/g enzyme concentration and 5.3 hours of reaction, 70% conversion is reached.

The project arises as a response to the business challenge presented to the University - Company - State Committee (CUUES) and the Research Results Transfer Office (OTRI), which expresses the need to have a technology-based system with the capacity to monitor and manage the cocoa traceability process during the storage and manufacture of chocolate. In view of the above, the objective of this article is to propose the use of the Holt-Winters model as a strategy to predict the behavior of environmental variables that could be present in the cocoa bean storage process, incorporating the use of techniques analysis supported in time series. According to the results obtained, the proposed model allowed predicting the behavior of temperature, relative humidity and dew temperature, as a strategy for the control of fungi and mold that could emerge in the grain during its storage. Additionally, the proposed model can be considered as a very important prediction tool during the cocoa traceability process, reaching adjustment levels higher than 0.9, accompanied by a very low standard error of estimation and with a confidence level of 95%.

The specialty coffees of the Department of Nariño have been recognized worldwide for their excellent quality, but they have been affected by the inadequate handling of the product in its supply chain, specifically in the areas where it is stored, directly affecting its differential attributes, therefore which presents an approach to solve the problem of selection and location of possible potential areas, for the establishment of a distribution center, essential for its entire chain. In the present study, a decision-making approach with multiple criteria (MCDA) was applied, specifically the analytical hierarchy process (AHP) and weighted linear combination (WLC), with the incorporation of geographical criteria and their implementation in GIS (Geographical Information Systems), where 38 possible alternatives (Producing Municipalities) were evaluated for the establishment of a distribution center, using criteria previously identified with the help of experts in the areas of location, logistics, connectivity and specialty coffees, where those selected were: production Municipal, road connectivity and average temperatures. As results, maps of normalized and weighted criteria were generated according to the qualification or level of importance given by the experts through the model (AHP) and later using the weighted linear combination method (WLC) and GIS, the possible ideal areas were identified for the establishment of the distribution center. In conclusion, we can affirm that as the number of criteria increases, it implies greater complexity for decision-making, being of great help the implementation of technological tools such as GIS for the analysis and management of information in the resolution of this type of problems, which in the specific case of this project brought us closer to having a departmental overview of the possible ideal areas to establish a distribution center for specialty coffees. In detail, the methods and criteria used, data sets used, results obtained and discussion, finally the most significant conclusions, are described. [ABSTRACT FROM AUTHOR]

Changes in chemical and sensory characteristics of Jamaica flower jelly during storage were determined. Fifteen kg of jelly were made and packed in 200 mL glass jars. Sampling for analysis was carried out every 30 days, determining: soluble solids, acidity, pH, monomeric anthocyanin, instrumental color, sterility and sensory evaluation. It was concluded that the technological process used for the elaboration allows its conservation for six months for both storage conditions. However, the jellies at 30 °C showed slight changes in some parameters such as color and concentration of monomeric anthocyanins, although they were not the reason for low scores from the judges. The product remained with very good overall quality and the ratings were between like and extremely like. [ABSTRACT FROM AUTHOR]

This research study aimed to explore the relationships between different phases of knowledge management: create, store, share, and apply knowledge. An exploratory study was applied with a sample of 35 academic unit leaders from five Chilean institutions. An econometric analysis was performed using the SPSS software. This revealed statistically significant relationships between different phases of the knowledge management process. The results showed that the application of knowledge depends directly on the sub-processes of creating and sharing knowledge. In addition, storing knowledge depends directly on creating knowledge and is required to explain the sharing phase. It is concluded that validating the variables examined, including their reliability, and exploring their relationships within a theoretical framework highlight the importance of promoting and enhancing knowledge management in each of its phases.

The Hass avocado is a climacteric fruit with high oil content and excellent organoleptic characteristics. The storage conditions (temperature and relative humidity) during transport and ripening are essential to guarantee that the fruit reaches the consumer with the best physicochemical and organoleptic characteristics. The objective of this work was to determine the combined effect of storage temperature during transport under refrigerated conditions and the ripening temperature, on the physicochemical properties of the Hass avocado exported from Valle del Cauca. A factorial design 32 was used, in which the factors corresponded to the storage temperatures (5, 7 and 9 °C) and ripening temperatures (17, 20 and 23 °C). In both cases, the relative humidity was 90 %. The fruits were stored for 20 days to simulate the export process, and the physicochemical properties were measured every 5 days. Subsequently, the fruits were submitted to ripening at 17, 20 and 23 °C until a maturity degree of 5, corresponding to the maturity of consumption. The best handling conditions were achieved at a storage temperature of 7 °C and ripening of 20 °C. The final product presented a homogeneous ripening, without internal defects.

Cocaine use has been related to neuropsychological disturbances that allow a wide spectrum of cognitive functions, however, the exhaustive analysis of the functioning of episodic memory is a vacancy area and knowing its in-depth processes would allow planning relevant interventions. Objective: To analyze the functioning of episodic memory in people with a diagnosis of cocaine use disorder. Methodology: Descriptive type design. Occasional sample, made up of 80 people, paired into two groups, clinical and control. To meet the objective The Spain-Complutense Verbal Learning Test was administered. Results: The clinic group presented a lower episodic memory performance than the control group. They achieved lower performances in three indicators of coding processes (spontaneous use of semantic strategies in immediate recall p = .03 and recall with short keys p = .01 and long-term p = .01), and two indicators of recovery processes (use of semantic strategies in short-term free memory p = .00 and long-term p = .00). Conclusions: These results suggested that people with a diagnosis of cocaine use disorder present a specific and primary deficit in the coding processes, related to to the little or non-systematic use of semantic strategies.

Objective: To determine the quality and physical dormancy of seeds from Desmodium incanum DC. (Fabaceae, Desmodieae) in the Entre Ríos province, Argentina. Materials and Methods: Fruits from plants of two neighboring natural areas, located in the Entre Ríos province, Argentina, were harvested. The collection was carried out between December and February, 2017-2018, on a surface of 20 m2 for each area. From the homogeneous set of seeds, the moisture content, seed weight, germination and viability, were determined. The permeability to water and longevity were modeled. The least squares was used as estimation method, and the higher determination coefficient, R2, was used as criterion for the model selection. Results: The harvested seeds showed low moisture content (8,2 %) and high quality. The germination essay showed low percentage of normal seedlings (3,5 %) and 95 % of hard seeds. In turn, 89,5 % of the embryos were observed viable. The proposed model proved different depth of physical hardness, and the fraction with high dormancy depth prevailed. Conclusions: The seeds of the species produced in the region showed high quantity of viable embryos; although most of the seeds showed deep physical dormancy. The hard seeds reached slow breaking of the physical dormancy in time, which originated normal seedlings, even after 22 months of storage. [ABSTRACT FROM AUTHOR]

The primary objective of this research study was to analyze the response area of mass transfer during storage in the supply chain of export-type yams (Dioscorea rotundata) by using computer tools. Yam samples were stored at different temperature conditions and storage times. The variable of interest was weight loss. A factorial experiment was developed with a completely random arrangement and a Tukey test, in triplicate. The results show that the increase in temperature and storage time increases the rate of mass transfer, generating high weight losses in the tuber. It is concluded that by using computational tools it was possible to efficiently determine that the factors examined have a significant effect on weight loss in yam porous structures.

Refrigeration is necessary to preserve the quality of watermelon fruits for longer, however, this technology is difficult to access and costly. Therefore, it is necessary to look for alternatives such as the selection of new varieties of watermelon that present good resistance to transport, superior fruit quality and high postharvest shelf life. In this context, the objective in this work was to evaluate the morphological, physicochemical and shelf life characteristics of the fruits of nine varieties of watermelon. It was conducted through a randomized complete block experimental design in a subdivided plot scheme. Nine varieties of watermelon were evaluated in the plots: Explorer, Magnum, Santa Amelia, Top Gun, Crimson Sweet, Electra, PX 397, Charleston Gray and Jubilee, and in the subplots five storage times: 0; 5; 10; 15 and 20 days. The edaphoclimatic conditions of the Amazon Savannah in Roraima, Brazil, favor the morphological, physicochemical characteristics and shelf life of the fruits of the Explore, Santa Amelia and Crimson Sweet varieties. The fruits of the watermelon varieties quickly lose their quality and are not suitable for in nature consumption after 15 days of storage at ambient temperature and relative humidity in the Amazon Savannah of Roraima, Brazil, since the content of ° Brix after this period is less than 9 °. The new studies related to the subject must consider the acceptance of the consumer market of the varieties with the greatest potential obtained. [ABSTRACT FROM AUTHOR]

Supply Chain Management is based on formulating models and methodologies to improve and optimize operations and internal processes, in order to increase efficiency and response capacity and simultaneously reduce costs. In Supply Chain Management, activities carried out in warehouses and distribution centers are critical to ensure an optimum service level and to obtain significant savings in total logistics costs. Slotting and picking are two fundamental activities in the efficient warehouses operation and management. For this reason, we made in this article an exhaustive bibliographic review on models and methodologies used for optimizing slotting and picking, between 2000 and 2018, identifying indirect applications in other types of industries and research opportunities and trends, considering the factors that influence the flow of materials and stochastic components in inventory planning: dynamic accommodation, route analysis, cluster location methodologies and warehouse division according to the type of products.

In this study the behavior of dry bee pollen during storage was evaluated, two storage temperatures 5 and 29 °C and two packaging materials were considered: amber polyethylene terephthalate (PET) bottles and double zipper polyethylene (PE) bags. The dry pollen was carried out physical-chemical measurements (humidity, acidity, pH and proteins) and microbiological (microorganisms at 30 °C, filamentous fungi and yeasts) every seven days to 70 days of storage. It was observed that the pH, acidity and protein values did not vary significantly (p > 0,05) during the period for any of the storage alternatives studied, while the humidity for the samples stored in the bags at room temperature showed an appreciable increase with respect to the initial value, from 5,17 to 7,33 %. In the case of microbiological indicators, no increase was observed during the period. [ABSTRACT FROM AUTHOR]

Objective. Microbiologically characterize dry and frozen pollen produced in the municipality of Viracachá-Boyacá. Materials and methods. Through a quantitative descriptive cross-sectional study, samples from 5 apiaries were taken, each with 10 hives, separating the pollen dry and frozen, determining for each sample: mesophilic aerobes, total coliforms, fecal coliforms, Staphylococcus aureus, Clostridium sulfite reducer, and fungus. The data obtained were analyzed according to international regulations and compared with research results in other countries. Results. Total and fecal coliforms were found in three of the five apiaries evaluated and only in dried pollen samples. Also, in two apiaries when dry pollen was analyzed, Staphylococcus aureus was found. The microbiological results of most samples are within the ranges of some international regulations; however, the best results in terms of microbiological quality were determined for frozen pollen. Conclusions. The pollen freezing process offers advantages related to maintaining microbiological quality compared to the drying process. It is necessary to evaluate the microbiological quality of both products throughout the storage time. [ABSTRACT FROM AUTHOR]

The purpose of this work is the study of the legislative developments included in the recent Royal Decree-Law 23/2020 of June 23, which approves measures in the field of energy and in other areas for economic recovery. These measures respond to the urgent purpose of trying to alleviate as soon as possible the effects of the serious economic recession caused by the Covid-19 health crisis that has suddenly shaken our country and the entire world. Combining both contexts, namely the climate emergency and the health and economic crisis, the Government proposes energy policy as a major protagonist and engine, the so-called "green lever" of economic and employment recovery, while trying to fulfill with the inescapable international commitments. The Royal Decree-Law under study has been approved within the framework of the parliamentary procedure of the Climate Change Law which has suffered an undesirable delay due to an amendment to the entirety, the Government deciding to accommodate within a Royal Decree-Law the approval of an abundant battery of measures that, due to the urgency in their implementation, had to be agreed as soon as possible in view of the need to put all possible means to promote economic recovery. In general, these are changes and novelties that respond to proposals that are highly demanded by the renewable energy sector, which, in general terms, applauds their adequacy, although, it should be said that these changes come late and out of time, especially taking into account that there are already several autonomous communities that have approved their own Law on Climate Change and Energy Transition. Thus, for example, Catalonia with Law 16/2017 of August 1, developed in the field of renewable energy through Decree-Law 16/2019 of November 26, Andalusia with Law 8/2018 of October 8 and the Balearic Islands with Law 10/2019 of February 22; as well as others such as the Basque Country and Valencia that are processing their draft Climate Change and Energy Transition Law. In the present work, we will analyze in detail the following measures: the new access and connection regulation to avoid speculation based on the technical feasibility and soundness of the projects; the new competitive competition mechanism for renewable energy projects, and auctions, trying to provide these technologies again with a predictable and stable remuneration framework; improving and simplifying the processing of authorization procedures for the construction, expansion, modification and operation of electrical production, transport and distribution facilities; the inclusion of the concept of non-substantial modification of generation facilities that have obtained administrative authorization in such a way that they must only obtain the operating authorization, prior accreditation of compliance with the safety conditions of the facilities and associated equipment; the incorporation of the criteria for the consideration of the same generation facility for the purposes of access and connection permits; the promotion of new business models; measures related to storage, independent aggregators, renewable energy communities, hybridization, high capacity recharging infrastructures (> 250kW), simplified authorization of R+D+i projects, regulatory test benches, simplified authorization of mobile network facilities, optimizing the use of the access capacity granted; improving energy efficiency by adapting the procedure for calculating the savings obligations of each obligated subject to provide the system with greater transparency and predictability for obligated subjects; the reform of the Environmental Assessment Law in order to streamline the procedures related to the scope document and the extensions of the environmental impact assessment and report, equating the regulation of these last two figures and, lastly, to ensure balance and liquidity in the electricity system, a necessary requirement for the continuity of activity and the promotion of new investments and, therefore, the success of the energy transition.

Prosopis ruscifolia is a promising forest species for restoration of saline areas that produces high quality wood and nutraceutical interest fruits. Its germination requirements and optimal storage conditions are unknown. The objectives of the work were 1) to evaluate different methods to stimulate germination, 2) to establish if there is an interaction between pregerminative treatments and the substrate used in laboratory tests (paper or sand), and 3) to analyze the effect of three different conditions of fruit storage on germination. Normal seedlings (PG), abnormal seedlings, hard and dead seeds were recorded. Three fruit samples were stored for eight months at 7 ± 2 °C, -17 ± 2 °C and the control at 25 °C. Afterwards, germination tests were carried out and the speed indexes (IVG) and mean germination time (TMG) were determined. Results indicated that chemical scarification with sulfuric acid was the most efficient pregerminative treatment to stimulate germination in both substrates. Immersion in water at room temperature showed the lowest percentage of germination in both substrates. The seeds of fruits stored at 7 ± 2 ° C had the highest germination percentage. Low temperatures improved velocity indices (IVG) and mean germination time (TMG). Results indicated the need for methods to overcome seed dormancy in P. ruscifolia and the excellent tolerance to low temperatures during fruit storage. [ABSTRACT FROM AUTHOR]

The genus Lupinus has potential use in ecological restoration, agroforestry systems, and commercial forest plantations, due to its ability to fix nitrogen to the soil. The physical dormancy of its seeds allows their storage for long periods. Its longevity is partially known. The objective of this study was to analyze the weight, moisture content, germinative capacity, germinative energy, and viability of seeds of L. bilineatus Benth., after they had been stored for 15 years in a glass jar at room temperature (fresh, approximately 10-15 °C), and without light. A randomized complete block design was used for the experiment and the ANOVA was performed with a mixed procedure. The treatments were: control, mechanical scarification (sanding with sandpaper), and chemical (5, 10, 30, and 40-min immersion in sulfuric acid), with a day/night regime of 25/20 °C, and a 12-h photoperiod (fluorescent light). The results were compared with those obtained 15 years before. The following results were obtained: 66 766.2 seeds per kg, with a 6.60% humidity (fresh basis), 45% viability (tetrazolium salts test), and a 3.2 d germinative energy. There were significant differences among the treatments (p ≤0.0001). Scarification with sandpaper favored a greater germination (48.9%). The annual decline rate of the germinative capacity was 2.24%. Scarification can eliminate the physical dormancy of the seeds. Scanning microscopy showed that the seed coat has cuticle, macrosclereids, osteoesclereids, and parenchyma. The seed of L. bilineatus without coat contains 52.15, 9.21, and 2.83% raw protein, raw fat, and raw fiber, respectively. [ABSTRACT FROM AUTHOR]

Neem seed (Azadirachta indica) contains triterpenoids with acaricidal and pest repellent activity in the agricultural sector. The concentration of the compounds in neem oil depends on the method of extraction. The hypothesis in this study was that the use of enzymes and solvents increases the release of Azadirachtin A (AzaA) from the neem seed, and its concentration remains stable in the extracts during storage at different temperatures. The objective was to determine the effect of hexane maceration of neem extracts prepared with Crystalzyme® PLMX, Crystalzyme® Cran, Crystalzyme® 100XL, and Cellulase 17600L on the extraction of azadirachtin A (AzaA) and its storage stability. The experimental design was completely randomized with three repetitions. The experimental unit was the neem seed collected from a plantation in Jamapa, Veracruz, Mexico. The loss rate constant (k) of AzaA in storage was determined by a first order equation. Data were analyzed with ANDEVA and the Tukey mean comparison test (p£0.05). The highest concentration of AzaA (2.73 g L-1) was obtained with CPLMX in hydrolysis and 24 h of maceration with hexane, with a greater proportion of the aqueous fraction (2.67 g L-1) than the hexane fraction (0.06 g L-1). The concentrations of AzaA extracted with the use of enzymes and hexane were similar to those obtained by ultrasound, mechanical pressing and methanolic extrusion. The loss of AzaA in the enzyme extracts increased with the increase in storage temperature, since it was not detected in the enzyme extracts after 7 and 28 d of storage at 50 and 30 °C, respectively. The concentration of AzaA (20%) remained constant 28 d after storage at 5 °C and showed the lowest k among the enzyme extracts. [ABSTRACT FROM AUTHOR]

In order to evaluate the acaricidal activity of the oil from Jatropha curcas L. seeds, with different storage periods, against larvae of the tick Rhipicephalus (Boophilus) microplus (Strain: Cayo Coco), this research was conducted at the Pastures and Forages Research Station Indio Hatuey. Oils with different storage periods (1 and 4 years) were evaluated. The oil was obtained from the mature, sun-dried and shelled fruits, of the Cape Verde provenance, collected in the Paraguay Farm, Guantánamo. A complete randomized experimental design was used with 17 treatments and 10 repetitions per treatment, from the different evaluated concentrations for the oils (0,5; 1,75; 2,5; 5 and 10 mg/mL), the solvent (Tween-80) and the negative (distilled water) and positive controls (Butox® Deltamethrin) used. For the in vitro studies the larval immersion techniques were applied. The negative control (distilled water) did not show acaricidal activity on the larvae (2,07 ± 0,40 %); a similar performance was observed in the solvent concentrations. The oil showed a marked larvicidal action in the two storage periods, with significant differences (p<0,05) among the experimental treatments, the negative control and the solvent, with values higher than 93 %. The best results were for the concentrations of 10 mg/mL oil 2014 (97,72 ± 0,58 %) and of 10 and 5 mg/mL oil 2017 (98,99 ± 0,33 and 98,11 ± 0,30 %, respectively), without significant differences with regards to Butox® (97,83 ± 0,45 %). The results showed that the oil from the J. curcas L. seed has acaricidal activity for the evaluated concentrations against larvae of the tick R. (B.) microplus, without significant differences between the storage periods and with values that exceeded 90 % of efficacy. [ABSTRACT FROM AUTHOR]

Blockchain technology is being introduced in all areas and procedures of verification, identification and recording of the virtual world. Some of its applications are simple translations of methods that are already being developed in other technical supports, but most of them provide new utilities that can change the technological context of scientific documentation. In this article we present an updated panorama of the initiatives based on blockchain for the management of scientific and technological documentation, highlighting those aspects that make this new technology a differentiated and authentically novel tool. A critical analysis with theoretical and practical considerations on its potential use completes the content of this work. [ABSTRACT FROM AUTHOR]

Background. The quality of the coffee bean has been related to its origin, the agronomic management and the storage conditions. Objective. To determine the activity of the polyphenyl oxidase, the lipid content, the color and the organoleptic characteristics of coffees from 3 experimental substations. Materials and methods. A completely randomized design was followed in a 3x6 factorial arrangement (places of coffee origin and storage time respectively). Results. The activity of polyphenyl oxidase is greater in fresh coffee-for the three provenances. The coffee from Naranjal presented higher enzymatic activities than the coffees from the Supía and the Catalina substations. The analysis of variance showed the effect of provenance on the enzyme activity variable. The activity of the polyphenyl oxidase in the coffees studied decreases with storage time. The lipid content is lower at a lower height in the Catalina. All coffees were characterized as good quality at zero storage time; but the characteristics of aroma, intensity of aroma and body presented ups and downs in the different months of storage. Naranjal coffee, on average, obtained an acceptable rating throughout the six months of storage. Conclusions. Significant differences were found for the variables studied due to the effect of provenance and storage. The enzymatic activity of the PFO showed activation / inhibition stages, during the six months of storage. [ABSTRACT FROM AUTHOR]

Introduction: Green coffee is a product of the world market whose price is determined by its sensory characteristics in the cup; however, these attributes change during storage, turning this stage of the production chain into a crucial stage to guarantee product quality. Objective: In the present work we sought to determine the impact of various storage factors on the sensory and physical quality of Colombian green coffee, under conditions of accelerated and natural stability. Materials and methods: Mature coffee cherries from the same harvest were processed in parallel by two post-harvest methods to obtain washed and semi-washed coffee, and then they were subjected to different storage treatments. Results: It was found that green coffee stored under environmental conditions had the characteristic notes of rest; in addition, density and color parameters changed differently in the two types of coffee. The behavior of green coffee in accelerated storage treatments varied according to the processing methods. For the case of washed coffee, storage with humidity negatively affected sensory attributes and also altered density, the RH % and color parameters L* and b*; for the semi-washed coffee, oxygen was the factor that promoted the greatest sensory changes, also affecting density and color. Conclusions: Different coffee post-harvest processes not only give rise to differences in the profiles of sensory quality but also condition the behavior of green coffee bean during storage.

The sector deposits in the walled complex Xllangchic An (ex Uhle palace), is composed of various structures (patios, plazas, hearings, deposits and roads) that when intertwine creates a context storage; but from this trait some questions are arise: What goods were stored?, Who controlled the storage?, How were the deposits?, How was the managed this sector?, What was the purpose of this activity? The storage of goods is an activity realized since very early periods and the late intermediate is not the exception, but the geography, environment and cultural load plays a transcendental role in the ways of realized this same activity, so in this early walled complex is estimated to record particular characteristics that differ it from other pre-Hispanic sites.

Climate change has altered the areas for forestry plantations (FP) and agroforestry systems (AFS), which provide goods and ecosystem services, such as mitigation of climate change at capturing carbon in biomass. The objective of this study was the estimation of total biomass and carbon storage and fixation in FP and AFS. This research was carried out in the Centro Universitario Regional del Norte (CURDN) of the Universidad del Tolima, located in Armero-Guayabal, Tolima. It was estimated the carbon storage and fixation in aboveground (AB) and bellowground biomass (BB) in seven FP and AFS. It was measured the total height and diameter at breast height (dbh) of trees with dbh>10 cm and diameter at 30 cm height (D30) in cacao plants in temporal sampling plots with different size. AB was estimated using allometric models or alternatively with biomass factor expansion. BB was estimated with a general model recommended by IP CC. FP between 5 and 25 years stored between 18.6 and 64.4 Mg C ha-1; whereas the AFS captured 85.0 Mg C ha-1 (10-15 years). The mean carbon fixation rate was 1.4 and 4.9 Mg C ha-1 year-1 for FP and AFS, respectively. The results showed the importance of these systems as mitigators of climate change and emphazises the advantages of involving AFS as carbon sinks allowing also the agricultural production.
