La investigación desarrollada lleva por título “Evaluación de la vulnerabilidad sísmica en edificaciones aplicando la metodología de INDECI en el Centro Poblado Virgen Asunta, Chachapoyas, Amazonas.”, se desarrolló con el objetivo de recolectar información para la evaluar los niveles de vulnerabilidad sísmica en las viviendas del Centro Poblado Virgen Asunta, que a continuación detallamos: En la Metodología; se efectuaron los cálculos correspondientes para seleccionar las viviendas a encuestar así mismo las técnicas e instrumentos de recolección de datos, se detalla las variables y su operacionalización. Posteriormente se procesan los resultados de la vulnerabilidad sísmica de las viviendas del Centro Poblado Virgen Asunta utilizando la metodología del INDECI, detallándose así las tablas y gráficos respectivamente, las cuales fueron obtenidas mediante las fichas de evaluación y verificación. De los resultados obtenidos se determinó que las viviendas presentan un nivel de vulnerabilidad sísmica bajo es de 0.0% de, moderado es de 11%, alto es de 19% y muy alto es de 69%. En conclusión, las viviendas que fueron evaluadas en el Centro Poblado Virgen Asunta, presentan vulnerabilidad sísmica alta. Lo que demuestra que la hipótesis planteada en la presente tesis es verdadera. Finalmente; se presenta las discusiones, recomendaciones, referencias bibliográficas y anexos

An enzymatic alternative for the synthesis of nucleoside 5′-monophosphates

A new procedure was carried out for the synthesis of nucleoside 5′-monophosphates, involving the use of two enzymes. The first step applied phospholipase D from Streptomyces netropsis and phosphatidylcholine as phosphatidyl donor, to give 5′-(3-sn-phosphatidyl) nucleosides (C, U, A, I). These were selectively hydrolysed in the second step by the action of phospholipase C from Bacillus cereus to produce the respective 5′-nucleotides. Application of this methodology on a preparative scale conducted to 5′-adenosine monophosphate in 63% overall yield from adenosine. The regioselectivity of these enzymes avoids protection steps, the overall synthesis is performed under mild reaction conditions and product isolation is easily achieved.Fil: Gudiño, Esteban Dario.

The influence of haiku composition tasks on the development of academic writing skills: a qualitative analysis

The inclusion of literary texts, particularly poetry, is not a common practice in the language classroom. However, the available empirical evidence, albeit relatively scarce, does suggest that poetry, when correctly employed, is likely to be beneficial for second and foreign language learners. This teaching material has been used to teach and develop areas such as vocabulary acquisition, grammar practice, and even motivation as well as the four macro-skills in language, namely listening, speaking, reading, and writing. The use of poetry in language instruction emphasizes the predominant role of learners in authentic literary production. As such, this research paper focuses on the qualitative aspect of a mixed-methods study about the effects of haiku composition tasks on the development of academic writing skills. The participants of the study were 30 English as a foreign language (EFL) pre-service teachers. As part of the data collection process, the participating students were asked to write short argumentative essays at the beginning and at the end of a six-week intervention that promoted the composition of haiku. After the intervention, an open-ended questionnaire was administered to identify and describe the participants’ perceptions regarding how haiku composition influenced their academic writing skills. The results of the study show that the great majority of the participants agreed that haiku composition furthered the development of their academic writing skills and vocabulary acquisition. The findings of the study corroborate the existing experimental findings as to the value of poetry-based tasks for second and foreign language learning. Thus, we conclude that the inclusion of poetry in the language classroom ought to be promoted through activities that, while being personal and meaningful to the students, allow for the development of language proficiency

Investigating the Feasibility of a Restaurant Delivery Service to Improve Food Security among College Students Experiencing Marginal Food Security, a Head-to-Head Trial with Grocery Store Gift Cards

Restaurant delivery services have gained in popularity among college students; however, students participating in the Supplemental Nutrition Assistance Program (SNAP) are not allowed to redeem their benefits via restaurant delivery services. This mixed-methods head-to-head crossover trial assessed whether college students experiencing marginal food security prefer benefits via a grocery store gift card (as a proxy for traditional SNAP benefits) or via a restaurant delivery service gift card of equivalent value, and which type of benefit is more effective at improving food security status. Thirty college students experiencing marginal food security were recruited to receive $80 in cash equivalent benefits to spend over a two-month period in the form of grocery store gift cards and restaurant delivery service gift cards. Participants completed surveys and interviews to measure their food security status and share their experiences with each benefit type. After four months of benefits, 48.3% of participants improved their food security status. However, neither type of benefit was statistically better at improving food security status. Most participants preferred grocery store benefits (89.7%) over restaurant delivery service benefits (10.3%). However, more research is needed to explore whether allowing SNAP recipients to redeem their benefits with restaurant delivery services is a viable mechanism to address food challenges among college students experiencing marginal food security

Drawing Clocks and Driving Cars: Use of Brief Tests of Cognition to Screen Driving Competency in Older Adults

OBJECTIVE: The purpose of the study was to determine whether a new method of scoring the Clock Drawing Test (CDT) is a reliable and valid method for identifying older adults with declining driving competence. DESIGN: Prospective cohort study. SETTING: An outpatient driving evaluation clinic. PARTICIPANTS: One hundred nineteen community-dwelling, active drivers with a valid driver's license, aged 60 and older referred for driving evaluation. MAIN OUTCOME MEASURES: The CDT and a driving test using a STISIM Drive simulator. RESULTS: The CDT showed a high level of accuracy in predicting driving simulation outcome (area under the receiver-operator curve, 0.90; 95% confidence interval, 0.82 to 0.95). CDT scoring scales were comparable and all correlations between CDT scores and driving performance were negative, implying that as the CDT score decreases, the number of errors increases. Interrater reliability of CDT scores was 0.95. Subjects scoring less than 5 out of 7 points on the CDT made significantly more driving errors, hazardous and in total (P <.001). CONCLUSIONS: The CDT can help establish problems with executive function and indicate the need for a formal driving evaluation. Our CDT scoring scale is a reliable, valid, and time-effective screening tool for identifying elderly drivers in need of further evaluation
