The objective of the work focused on characterizing the biodiversity of Phytophthora spp. and rhizobacteria with potential for biocontrol in black pod disease in CCN-51. Nine plant samples with symptoms of the disease were collected from cocoa-producing areas, evaluating their morphological characteristics and identification by PCR. Different morphotypes of colonies are observed: cottony, regular and starry edge characteristic for Phytophthora spp. Electrophoresis profiles reveal an amplicon of 159 bp for P. palmivora, demonstrating its distribution in the nine zones. The tests on mycelial inhibition in vitro to P. palmivora, determined high levels of antagonism of 78 and 60% by direct confrontation with the rhizobacteria. These results in bio-protection to CCN-51 by applications of P. veronii R4, A. calcoaceticus BMR2-12, S. marcescens PM3-8 and P. protegens CHA0 are effective in the co...

This review paper addresses the need to infuse intercultural learning in the language classroom. The body of literature offers evidence of language approaches and methods that can potentially benefit the foreign/second language classroom by shifting from traditional practice to more active, participatory, and interculturally infused teaching. Teaching a foreign/second language comprehensively requires the inclusion of the intercultural component to equip learners with the ability to interact in increasingly intercultural contexts. Therefore, this paper proposes a model to design language and intercultural tasks in the language classroom. The methodology applied in this paper is based on a qualitative approach by reviewing the literature to gather insights to facilitate an intercultural approach based on a hybrid pedagogy merging Content and Language Integrated Learning (CLIL) and Project...

Starting from the concept of creative industries, this article focuses on the potential of intellect and creativity as key factors for development and creation of wealth in Peru.Attention is paid to how the implementation of development policies in the field of creative industries presents itself in Peru. This article reviews diverse data representing different manifestations of creative industries, and the analysis thereof shows two things: on the one hand, the Peruvian State insists on deploying scarce resources to these areas, and, on the other hand, it gets lost in projects which due to their disconnection from experience and practice of local organizations and initiatives end up being too distant from the reality in Peru. Finally, this article provides proposals, in particular the Internet as platform for development and diffusion of intellect in Peru.

Financial inclusion in Peru faces considerable difficulties due to low levels of access to financial services such as loans and savings accounts. To address this challenge, electronic money emerges as a tool that could potentially reach populations underserved by traditional banking. Therefore, the widespread use of mobile telephony in Peru is essential to promote financial inclusion in economically vulnerable populations. In this sense, the objective of this article is to analyze the legal framework of electronic money, as well as the barriers to access in the supply and demand of financial services. It concludes that e-money can bring essential financial services to previously underserved populations, taking advantage of the existing mobile infrastructure.
