The article examines the development of speech in elementary school students. The research objective is to determine the status of coherent speech development in 3rd-grade students in the process of constructive and artistic activity. The article defines the criteria (structural and compositional, communicative and productive, and communicative and creative), indicators, and levels of development of coherent speech in elementary school students in the process of constructive and artistic activity. Each criterion includes a group of qualitative content-disclosing indicators and characterizes the achievements of students in the intended type of activity. Based on this, the authors have developed a methodological tool that allows them to diagnose coherent speech development in 3rd-grade students in the process of constructive and artistic activity and to conduct a precise quantitative diffe...

In the camu camu (Myrciaria dubia) processing, the peels and seeds are the main residues with a high potential for use as they contain anthocyanins (peel) and phenolic compounds. The objective of this research was to take advantage of camu camu peels and seeds as ingredients for infusion filters, and to evaluate the effect of drying. First, the peels and seeds were dehydrated at three temperatures (50, 65 and 70°C) and characterized in total anthocyanins and total phenolic compounds. Then, they were sieved considering two size ranges: small (between 0.1 and 0.475 cm) and large (larger than 0.475 cm) to be evaluated sensorially by a trained panel as an infusion, using a hedonic scale of general acceptability of 10 cm. The results showed that the peels contain anthocyanins and a higher content of phenolic compounds. In the case of the sensory evaluation, the panel preferred the large-rang...

The massive use of social networks and the anonymity that this provides has made possible not only the immediate communication between users, but also the spread of hate speech against certain groups of our society in the form of offensive messages to them, this has led to a serious social problem, which remains a topic of current research along with NLP. The purpose of the present work is to make a comparison of our "HateCheck" recognition model against the author's results, using the same database as them. To do so, we will make use of the main metrics such as: precision, recall and F1.

Music source separation is the task of isolating the musical phrases played by different instruments recorded individually and arranged together to form a song. Nowadays, several methods have been developed to cover the separation of music sources, which can be classified into supervised and unsupervised learning, however, no research has been developed in which the effectiveness of using different methods together are analyzed , that's the reason the present work seeks to measure the results of the use of two methods, REPET + (unsupervised) and UNet (supervised), jointly and in isolation to separate the music waves produced by a singer and the waves from the instruments. The results show an overall score (SDR) of the methods for vocal separation for the UNet network was 5.38 dB, REPET+ -4.3 dB, -2.55 dB for REPET+ & UNet, -0.38 dB for UNet & REPET+, -6.16 dB for REPET+ & REPET+ and 5.17...

Peasant agriculture and its agrobiodiversity systems are at a juncture in which two global processes impose significant challenges for their sustainability: climate change and the expansion of agricultural biotechnology supported by a regimen of intellectual property rights over plant genetic resources. In this article, I explore some potential risks these global processes impose on peasant agriculture, particularly on their seed systems. We analyze how, in response, peasant communities have increasingly mobilized around two converging political agendas, seed sovereignty and climate justice. In addition to the political achievements confronting some of the great biotechnology and corporate developments in the context of climate change, community peasant actions implemented to protect and defend their seeds directly contribute to reaffirming peasant seeds as part of peoples’ commons and...

The objective of the present study was to evaluate the extraction and microencapsulation of antioxidant compounds from Oenocarpus bataua Mart seed, commonly known as “ungurahui” or “patawa”. The extraction process was performed in an ultrasonic bath and the orthogonal composite central design of the response surface methodology (RSM) was used to determine the optimal extraction conditions, using two factors: ethanol concentration (48.44 to 91.56%) and extraction time (13.83 to 46.17 min). The optimal extraction conditions (48.44% ethanol and 13.83 min) allowed to obtain the extract (EUL) with the highest number of antioxidants (yield (YI): 24.64%, total phenolic content (TPC): 452.76 mg GAE/g EUL and DPPH: 74.26%). Microencapsulation of EUL with maltodextrin by spray drying produced microcapsules (EUM) of homogeneous size (5 µm), without cracks or fissures and that preserved its...
