The industrialization of potatoes in Peru constitutes a business opportunity to increase the supply of processed potatoes, generating added value for small producers. For this reason, it is important to have varieties suitable for frying and thus supply the potato value chain for the processing industry (french fries) and snacks (flakes). It is described the origin and genealogy of the clone UH-24 (“Bicentenaria”), its agronomic characteristics through the identification analysis, the way how it developed and multiplied in the greenhouse and in the field, as well as the evaluation process through the analysis of adaptation and efficiency in four environments of Lima region. The potato variety Bicentenaria has good production and adaptation capacity in the central coast of Peru, with a mean tuber yield of 43.2 t ha-1, compared to the commercial varieties Canchán and Diacol Capiro wit...

This research was developed to investigate how literary discourse rightly contributes to the knowledge of reality and allows the readers to develop their ideas about the context surrounding them or the production of artistic texts. It established the confi guration of culture and interculturality, the artistic contributions of the poetry of the Generation of 50 in the process of Peruvian reality from the perspective of literature through a critical and refl exive reading of theoretical texts, critical texts (metatexts), and artistic texts (the poetry of the Generation of 50). In this way, we see that literature becomes a means of artistic expression to display the author's intercultural competence and the interpretative capacity of the reader. Keywords: artistic expression – context – poetry – literary discourse

Industrial effluents without treatment or supervision by the authorities pollute the environment. Solving the problem does not go only by the control, supervision and penalties for companies that generate effluents, require its own investigation as well as develop specific treatments, accessible and affordable that can be adopted by each industry. The primary treatment is removal by physical or chemical means a substantial part of sedimentable or floating material, reducing an important fraction of the organic load, which represents a significant percentage of solid contaminants. Within the types of primary treatment quote coagulation and flocculation. The main objective was to evaluate the efficacy of two coagulants in reducing the pollution potential of effluents from the fruit processing plant. To make the primary treatment: were assayed two chemical substances, aluminum sulfate as in...

The aim of this study was to extract collagen from the waste produced in the processing of anchovies (canned and surimi). To this end, non-collagenous proteins was solubilized with a solution of 0,1N sodium hydroxide and neutralized with successive washes with water (pH close to neutral). Then, the residues were decalcified with a EDTA 0,5M solution; degreased with butanol 10% and finally the collagen protein were solubilized with acetic acid 0,5M and precipitated with sodium chloride 2,6M. Collagen precipitated was dialyzed and lyophilized. The hydroxyproline content (Hip) were quantified in waste and lyophilized collagen, getting the values of 6,5 and 52,9 mg of hydroxyproline/g sample, respectively. The solubility of lyophilized collagen decreased about 40% at a concentration of 12% NaCl. Gel electrophoresis showed a strong band of approximately 110 kDa molecular weight that correspon...

The unique process has been strengthened with the adoption of two directives within the Judiciary, which promote virtuality, concentration of procedural acts and orality. In this way, this branch of the State evidences its commitment to the progress of family procedural law and the expeditious settlement of cases in favor of children and adolescents. The author of this article analyzes directives from the jurisdictional scope, developing contributions for the correct use by the judicial user.

Fructooligosaccharides (FOS) are fructose polymers, linked by β-glucosidic bonds (2-1), considered low caloric food sweeteners with prebiotic function and can be obtained from sucrose by biosynthesis. The fruits of the carob tree (Prosopis pallida) contain mainly carbohydrates where sucrose stands out. For this reason, the production of FOS from carob extract was optimized using a pectinase from A. aculeatus. The response surface methodology using was applied to optimize the parameters that affected production: time, temperature and carob extract; then they were verified experimentally. The biosynthesis process of FOS was carried out with carob extract at the concentrations of 20, 35 and 50 ° Bx, Pectinase at 10, 35 and 61mg, at 45, 55 and 65 °C for 0,5, 9,5 and 18 h, with stirring at 150 rpm The analysis methods were glucose oxidase and AOAC 999.03, for glucose and FOS respectively a...

The coffee industry, coffee shops and restaurants are in constant expansion and growth. Consequently, large amounts of Spent Coffee Grounds (SCG) are generated, which are solid coffee residues obtained after the ground coffee leaching process. This residue can be reused because of its compounds as phenolics. The objective of the present study was to evaluate the effect of extraction time (30-90 min) assisted by ultrasound (45kHz and 50 W), liquid-solid ratio (10-40 ml/g) and ethanol concentration (20-93.8%) in the total phenolic compounds (CFT) content expressed as mg gallic acid/g SCG dry matter. Surface response methodology (MSR) was used, as an efficient technique that minimizes the number of experiments, through the central rotational compound design (DCCR) to determine the effect of these 3 factors and to perform the optimization of the extraction process conditions of total phenoli...

This article presents the virtues and results of the order for payment process applied in other latitudes to show that it is a process that, far from the discussion of its legal nature, manages to resolve conflicts submitted to this in a reasonable time. Then, the minor labor processes that are processed under Law No. 29497 are analyzed. It is concluded that these processes can be adapted or submitted to the order for payment process, which would allow their processing and resolution to be carried out within a reasonable time, thus achieving the speed proclaimed by the new labor procedural law.

This study aims to know how the training processes of practicing teachers contribute to the construction of beliefs about teaching at the university. Froma qualitative methodology with agrounded theory approach, professors from public and private universities were selected through theoretical sampling. In-depth interviews were conducted to collect data whichwere analytically coded. Among the results it was found that the teachers' beliefs come frominstitutional training of a normative typewhich emphasizes a functional teaching in didactic techniques, use of technology and innovation, excluding training in knowledge of the discipline they teach. Thus,it was also found that teachers carry out self-training processes on a personal initiativefor updating scientific knowledgeand develop their practices teaching with strategies that they themselves use to learn, because they believe in their o...

This work describes the isolation and selection of bacterial strains of the genus Pseudomonas in Cetrimide, Acetamide and King B Agar media, from effluents of the leaching process and from the tailings deposit of the gold ore processing plant, Caraveli - Arequipa. Subsequently, the adaptation was made in Modified Mineral Medium (M9M), to different concentrations of sodium cyanide, to evaluate the tolerance and degradation of the CN- radical. The results of sowing in different nutrient media allowed us to observe changes in coloration with a change from clear to intense red in Acetamide Medium and from clear to fluorescent green in King B Agar Medium, revealing the presence of P. pseudoalcaligenes bacteria. Similarly, during the adaptation process of a strain whose initial cell population was 2.0E+06 CFU/mL, in media supplemented with 50, 100, 150, 200 and 250 ppm of Free Cyanide, at the ...

La pitajaya (Selenicereus megalanthus) es una fruta exótica que se encuentra en las selvas amazónicas, en el caso de Perú, se encuentra con mayor frecuencia en la selva alta. Se caracteriza por tener alto contenido de vitamina C y antioxidantes, lo que la hace apetecible de ser comercializada. Respecto a su procesamiento, este debe ser realizado cerca a la fuente de materias primas, para reducir los costos que se generen. Por el tipo de fruta, no cabe duda que ya procesado puede ser considerado una oportunidad para los pueblos amazónicos eleven su nivel de vida comercializando la pitajaya.
