This article analyzes El azul de las abejas (2014), by Laura Alcoba, emphasizing its almost happy ending: a girl who, after having experienced a violent past in Argentina, exile and a laborious itinerary, manages to settle in another language, French, and thus build a new identity as a writer. In addition, the works produced by Alcoba dialogue with other artistic productions by children of militants in Argentina: Diario de una princesa montonera (Mariana Eva Pérez, 2012), Pequeños combatientes (Raquel Robles, 2013) and the photographic exhibition Arqueología de la ausencia (Lucila Quieto, 2011). This transmedial richness enables us to think about new articulations of meaning in relation to memory construction in the Southern Cone.

This paper analyzes space as a key element for the study of three Chilean contemporary writers: Guadalupe Santa Cruz, Lina Meruane and Diamela Eltit. In their novels, urban space appears a way for questioning the established canon, since the literary representation of the real city arises from a new urban rhetoric: one that elaborates other ways of conceiving the relationship between signifier and signification according to the real referent –whether urban, landscape, maps, cartographies, inhabitation–, and the imaginary communicative situation inherent to novels.

This paper analyzes the novel Ramal (2011), by Cynthia Rimsky, searching for the particular relationships between space and image. On the one hand, the material characteristics of photographic images in the novel are analyzed to understand how they dialogue with, and intervene in, the configuration of the verbal narration and its particular tones and operations of display and invisibility. On the other hand, landscape is thought of as a fundamental device for the narrative policy of the novel. The main object of this article is the articulation developed by these two devices in order to generate an ambiguous and problematic characterization of the protagonist’s genealogy.

Jaulas, Short Stories by Mauricio Montenegro

This study was carried out in the intertidal zone in the Escalante Chacocente River Wildlife Refuge, Santa Teresa municipality. Its main objective is the determination of the association of the species Arbacia lixula and Ophiocomine nigra based on physical-chemical variables in rocky strata. The diversity of the species Arbacia lixula and Ophiocomina nigra was quantified, through indexes of biological diversity, horseback riding, specific wealth and their distribution in rocky ecosystems through Temporal Space distribution patterns. Sampling was carried out at two times (Dry and Rainy), from January to June in 2018, in 5 rocky strata on Chacocente Beach. The samples were collected through a 1 m2 metal frame. Physical-chemical variables (Temperature, Salinity, pH and OD) were determined. The community structure of the ecosystems consisted of 3 Phylum: Echinodermata (Class Echinoidea and Ophiuroidea), Mollusca (Class Bivalvia and Gasteropoda) and Arthropoda (Malacostraca Class), having 26485 organisms in the two sampling times. The lowest density was found in the dry season (2.99 ind/m2) and the largest in winter with 3.5 ind/m2. The abundance and distribution of species was heterogeneous in the rocky strata. With the Jaccard and Morisita-Horn index, they had high similarity between the rocky strata.  The most abundant species was arbacia lixula, having greater ability to adapt to the different changes that occur in rocky ecosystems than Ophiocomine nigra. As for the composition, distribution and association of species they related to the physicochemical variables of seawater, where variations and fluctuations determine that both species adapt perfectly to changes, allowing them to be associated. As for their ecological importance, these species are good indicators of systemic echo quality, allowing the recruitment of new species in rocky ecosystems.

The potential use of Moringa oleifera, generates interest to investigate the potential characteristics of promising genetic materials. With the objective of morphological characterization Moringa oleifera cv Honghe plants based on height and basal diameter of plants, number of branches and leaves, number of fruits per plant, length and equatorial diameter of the fruit, number of seeds per fruit and per kilogram, weight, length and diameter of each seed, survival rate, beginning of flowering and fruiting during its initial establishment, a study was carried out at the National Center for Agricultural Research (CNIA) of the Nicaraguan Institute of Agricultural Technology, in Managua, Nicaragua , with 12 trees established at a planting distance of Four meters between rows and between plants in an area of 172.50 m2. Descriptive statistics were used for data analysis. The results show a survival rate of 91.66 %, height 277.16 cm, basal diameter 5.13 cm, number of leaves 51, number of branches seven, beginning of flowering, at three months of age, with 100 % flowering, at five months of age, beginning of fruiting at 5.5 months of age, with 100 % fruiting with seven months of age. Fruit production per plant was 65 ± 27, fruit length 52.83 ± 5.22 cm, equatorial diameter 1.93 ± 0.38 cm and 21 ± 4 seeds per fruit. The seeds presented mean weight of 0.3366 ± 0.06 grams, length 11.38 ± 1.35 mm, diameter 10.26 ± 0.99 mm and 3.002 ± 30 seeds per kilogram. These results allow to conclude that Moringa oleifera cv Honghe is a promising genetic material because it is a very early and fast growing cultivar, compared to other provenances and cultivars evaluated by other authors in our country.

This research was aimed to study the morphometric, faneroptic dimorphism and variability of crossbred goats from rural communities in the municipality of Nindirí. From a total population of 208 animals, 35 adult individuals were evaluated by random sampling, from which 13 morphological measures, 13 phaneroptics, 9 zoometric indices and the biological variables, age and live weight, were determined. Age and live weight in males presented the lowest values, but with the highest level of variation. The cephalic measurements raised and the longitudinal (DL) and dorsal sternal (DDE) diameters did not present a very marked dimorphism between sexes. Chest width (AP) and rump measurements, width (AG) and length (LG), were slightly greater in females, with high levels of variability. The thoracic and cane perimeters did not show very marked differences between both sexes. The morphostructural homogeneity of these animals is high, 76.92 % of the variables present a coefficient of variation between medium to low (coefficient of variation less than 10 %), being the raised those that present the lowest proportions of variability. Based on the ethnological and productive capacity indices, the animals would be morphologically, dolichocephalic, not very compact, medium-sized, convexilinear and Brachymorphic. The values of the pelvic indices longitudinal (IPEL) and transversal (IPET), reveal a lack of specialized productive attitude. The phaneroptics were dominated by: layers, mucous membranes and dark hooves, hair of medium length and absence of raspil, breeches, goatee and mamellas.  In the morphological characteristics, the straight nasal fronto profiles, horizontal medium ears, acorn, depigmented udders, and bagged, nipples with normal numbers and parallel position stood out. Less than 50 % of the positive and significant correlations were found, so this population can be considered a morphostructural model that is not very harmonious. Four main components (PCA) explained 77 % of the total variation, highlighting within them seven variables with greater discrimination power

The present research addresses morphological aspects of the plant and evaluates the behavior of vegetative development of oregano (Plecthranthus amboinicus (Lour.) Spreng) through the establishment of stems at nursery level using a Randomized Complete Block design, over a period of 90 days. Each block was composed of 30 plants, with three replications for a total of six blocks with 180 plants. Three measurements were made at 30-day intervals. The variables were: survival, number of leaves, plant height, and leaf length and width. Three types of substrates were used; 1) 100 % soil, 2) a mixture of 35 % soil, 30 % sand, 30 % bokashi and 5 % lime, 3) 35 % soil, 35 % rice husk and 30 % sand. In the laboratory, the percentage of biomass in green and dry weight (root and aerial) was calculated to check the moisture content of the plant. The bokashi substrate presented the best results in terms of organic matter and nitrogen. Plant growth was better with the bokashi substrate when obtaining the highest values; in terms of stem survival, a general average of 64% was recorded, with no difference between the factors or in the interaction; in terms of the number of leaves, the bokashi substrate in large bag obtained 41 leaves, in length and width of the leaf, 6.07 cm and 5.32 cm were recorded respectively, and 32.46 cm in plant height, all these results obtained in the moisture content of the plants was higher (86%) with the bokashi substrate.

Citrus fruits are the most economically important fruit crop in the world. In Nicaragua, citrus production generates USD 24.5 million annually. The diseases that can be prevented by inoculating mycorrhizae in rootstocks are root rot caused by Phytophthora sp. and the dry disease of citrus by Fusarium sp. The introduction of disease resistant patterns is a necessity in today's citrus industry. In the last decades, arbuscular mycorrhizal fungi have been used for the beneficial effect they produce on their hosts. The objective of this study was to evaluate the effect of arbuscular mycorrhiza on the vegetative development of Citrange Troyer and Citrange Carrizo rootstock. The inoculated mycorrhizal fungi were isolated from the Félix, Marino and San José citrus farms. The genus identified with the highest percentage was Glomus sp, with 97 % to 99 %, while the genera Scutellospora sp., Gigaspora sp., Septoglomus sp. and Acaulospora sp., represented 1 % respectively. The percentage of root colonization with the Glomus sp. genus was 93 % for the Troyer graft holder and in Carrizo it was 83 % to 100%. The effect of Glomus sp. was evaluated by measuring the variables plant height (cm), number of leaves, stem diameter (mm), root length (cm) and biomass (g). The results of the analysis of variance and separation of means of Tukey (α = 0.05), show significant differences for the Troyer rootstock in the variables stem diameter and root length with the isolate from the San José farm, in the case of the root Carrizo graft the number of leaves, stem diameter and root length showed the highest values with the isolate from the Felix farm.
