Spatial modeling with repopulation potential for three flora species of Huaytapallana Regional Conservation Area, Peru

In the high mountain ecosystems of the Huaytapallana Regional Conservation Area (ACR-H) there are three species of flora (Krapfia macropetala, Gentianella scarlatinostriata and Senecio canescens) of social, economic, cultural and medicinal importance, however their population status and undefined local distribution make these species area more vulnerable to extinction. Therefore, the objective of this work is to determine the population distribution for repopulation purpose in the ACR-H from the potential distribution in Peru using Maxent algorithm and a local model developed with the Saaty pairwise hierarchy matrix, adding a soil sample for a better application of the final model. The results show that the Species Distribution Models (SDMs) have a high confidence because the Area Under the Curve (AUC) surpass 0.90. Otherwise, the local model is consistent by showing a Consistency Ratio (CR) of less than 0.10. As a final result, all species obtained optimal spaces for repopulation near the Huaytapallana Cordillera, where Krapfia macropetala obtained the largest extension (715.334 ha) and Gentianella scarlatinostriata is the smallest (650.096 ha). Further there were no differences in the parameters evaluated in the three soil samples, which facilitates the application of the models for the repopulation of these three species

Prepositional error analysis in EFL students' written compositions

This research project, developed at Uniminuto University, emerged from the difficulties that the lexical category of prepositions causes to EFL learners in general. The researchers were interested in analyzing how a group of students used prepositions in a written task taken from one of their exams. In order to approach the understanding of this phenomenon, the researchers based the analysis on the interlanguage hypothesis, which states that second language learner’s errors are a key to understand their interlanguage (linguistic system) in terms of prepositional usage. As for the methodology of analysis, researchers decided to use the method known as Error Analysis, which is a systematic procedure for analyzing linguistic samples by using taxonomies. 55 EFL learners participated in this research, the group belonged to the course Anglophone Language and Culture VI and the students came from four different groups. After completing the analysis, the conclusion is that prepositions presented a difficult challenge for all the levels of proficiency within the selected courses, and intralingual strategies of learners mainly produced such errors

Propuesta de materiales RCD, para el reforzamiento de la subbase granular en pavimento asfáltico en la calle Sicchez, urbanización Santa Rosa, distrito de 26 de octubre, Piura

En nuestro territorio, como en muchos otros países, existen problemas que aquejan a nuestra comunidad conjuntamente con el medio ambiente, uno de ellos es la contaminación por materiales residuales provenientes de obras de construcción y demoliciones, o ya sea de cualquier estructura que posea concreto; Esto nos lleva a pensar que deberían existir métodos o soluciones para poder reutilizar dicho material. En eso se basa nuestro proyecto, estudiar dichos materiales reciclados, su composición, su estructura y sus propiedades, para ser utilizados, como componentes de la subbase granular para el diseño de un pavimento flexible, en la Calle Sicchez, Urbanización Santa Rosa, distrito de 26 de octubre, en la ciudad de Piura. Este material tendrá que pasar por los rigurosos ensayos de calidad, así como también determinar sus propiedades mecánicas y físicas, y así demostrar si son aptos para la conformación de la subbase granular. Dicho esto, detallaremos en nuestros estudios todos los aspectos correspondientes a la calidad y sus propiedades, para determinar que porcentajes pueden usarse al compartir composición con agregados naturales

Extensional and Intensional Strategies

This paper is a contribution to the theoretical foundations of strategies. We first present a general definition of abstract strategies which is extensional in the sense that a strategy is defined explicitly as a set of derivations of an abstract reduction system. We then move to a more intensional definition supporting the abstract view but more operational in the sense that it describes a means for determining such a set. We characterize the class of extensional strategies that can be defined intensionally. We also give some hints towards a logical characterization of intensional strategies and propose a few challenging perspectives
