El objetivo de esta investigación fue la reducción de las trazas de materia orgánica en el agua potable por medio del uso de zeolita natural, zeolita activada y la comparación con la eficiencia de la adsorción del carbón activado. Se utilizó agua suministrada por la compañía AGUAPEN E.P. y materiales adsorbentes zeolita natural, zeolita activada y carbón activado. La zeolita se activó térmicamente a 600ªC. Se realizaron pruebas en columnas de adsorción a escala (RSSCT – Rapid Small-Scale Column Test) para carbón activado granular (GAC) de acuerdo a la norma ASTM 6586 para determinar la eficiencia de la adsorción de las trazas de materia orgánica en el agua potable. Se determinó la eficiencia en base al parámetro de carbono orgánico total en muestras simple del afluente y efluente del agua tratada cada 3 horas durante 24 horas. El incremento de la presión de trabajo evidencia el punto de ruptura o colmatación del adsorbente. La concentración del Carbón Orgánico Total (COT) se determinó mediante el análisis de la combustión de la muestra con el detector infrarrojo no dispersivo de dióxido de carbono (CO2). Los resultados mostraron reducción de materia orgánica con el uso de zeolita natural y zeolita activada, con respecto al carbón activado.AbstractThe objective of this research was the reduction of organic matter traces in drinking water through the use of natural and activated zeolite, and the comparison with the efficiency of activated carbon adsorption. Water supplied by the company AGUAPEN E.P. was used, and adsorbent materials as natural zeolite, activated zeolite and activated carbon were utilized. The zeolite was thermally activated at 600 ° C. Tests were performed on scale adsorption columns (RSSCT - Rapid Small Scale Column Test) for Granular Activated Carbon (GAC) according to ASTM 6586 to determine the efficiency of the adsorption of traces of organic matter in drinking water. Efficiency was determined based on the total organic carbon parameter in simple affluent and effluent samples of treated water every 3 hours during 24 hours. The increase in working pressure shows the point of rupture or clogging of the adsorbent. The concentration of Total Organic Carbon (TOC) was determined by analyzing the sample combustion with a non-dispersive infrared carbon dioxide (CO2) detector. The results showed the reduction of organic matter in natural zeolite and activated zeolite compared to activated carbon.

La búsqueda del sentido a la vida ha sido una constante en todas las esferas de desarrollo humano. La práctica orientadora —trasformada en disciplina orientativa— ha estimulado la capacidad de decisión de las personas mediante procesos de autoconocimiento, información y toma de decisión. Desde los enfoques funcionalista, evolucionista, factorialista, humanista e histórico-cultural, hasta los nuevos postulados de la post-modernidad, la orientación se ha constituido en un mecanismo utilizado en diferentes contextos sociales para reproducir modos de producción o para reivindicar derechos individuales y colectivos. Muestra de ello es el desarrollo de dicha disciplina en el contexto ecuatoriano, donde la evidencia cronológica muestra el cambio cualitativo de enfoque: desde lo vocacional y profesional a un abordaje centrado en derechos. El presente ejercicio de investigación descriptiva esboza el desarrollo del concepto de la orientación en cada uno de sus estadios históricos en el Ecuador, su implicación en la normativa nacional e internacional a más de establecer un punto de conexión con el goce mismo de los derechos y libertades individuales y colectivas. Finalmente, se deja abierto un escenario de inquietudes con respecto a la práctica orientadora en la nueva sociedad del conocimiento e información. AbstractThe search for meaning in life has been a constant in all spheres of human development. The orienting practice -transformed into orienting discipline- has stimulated the decision capacity of people through processes of self-knowledge, information and decision making. From the functionalist, evolutionist, factorialistic, humanist and historical-cultural approaches to the new postulates of post-modernity, orientation has become a mechanism used in different social contexts to reproduce modes of production or to claim individual and collective rights. An example of this is the development of this discipline in the Ecuadorian context, where chronological evidence shows the qualitative change of approach: from the vocational and professional to a rights-centred approach. This descriptive research exercise outlines the development of the concept of orientation in each of its historical stages in Ecuador, its implication in national and international norms, and more than establishing a point of connection with the very enjoyment of individual and collective rights and freedoms. Finally, it leaves open a scenario of concerns regarding the guiding practice in the new knowledge and information society.

Este estudio tiene como finalidad relacionar inflación con la disponibilidad de efectivo en la economía venezolana, en el período 2005-1 al 2018-2. Sobre la base de la teoría cuantitativa, este trabajo de carácter descriptivo y explicativo, con el uso de regresiones polinomiales y el criterio de función total y marginal, se procedió a relacionar el circulante en poder del público y la banca con la base monetaria (BM), los ingresos del gobierno por señoreaje y la estimación de una ecuación de demanda de dinero para Venezuela en hiperinflación. La investigación muestra evidencias de que la tasa de variación promedio inter-trimestral de la BM es superior al de la liquidez monetaria y el circulante, produciéndose una caída del efectivo disponible en poder de la banca en los últimos 5 trimestres, al igual que la demanda de dinero en los últimos 10 trimestres; producto de la política monetaria expansiva implementada por el Banco Central de Venezuela (BCV), que se ha traducido en una tasa de inflación promedio del 30% inter-trimestral, decantándose en un proceso hiperinflacionario en los últimos 3 trimestres del periodo estudiado; donde toda la BM creada por el BCV fue cubierto por títulos valores en divisas y moneda nacional equivalente al 89% de su activo total al cierre de 2017.

Para determinar la eficiencia del número de hembras vírgenes (HV) en la captura de, machos adultos de Plutella xylostella L, se diseñaron y se instalaron trampas delta provista de jaulas conteniendo uno, dos, tres HV y un testigo en blanco (jaula vacía) con tres repeticiones, en los cultivos de las Brassicaceas, a una distancia de 35 m entre las jaulas evitando el rango de traslape de feromonas de la hembra. El registro diario en horas de la mañana durante tres días consecutivos con el recambio de hembras al sétimo día en tres ocasiones permitió determinar la eficacia de los tratamientos. Los tres tratamientos presentaron la captura de adultos siendo el tratamiento con tres HV el que presentó mayor número de adultos capturados (767) por encima de 16 adultos/día, seguido por el tratamiento con dos HV (199), el tratamiento con una HV (22) y finalmente el testigo que no presenta captura, con diferencias significativas comparado con los otros tres tratamientos (p<0.05). Los resultados obtenidos demuestran que la mayor captura está relacionada al número de HV colocadas debido a la concentración de feromona emitida por las hembras vírgenes.

The Impact of a Patient Safety Program on Medical Error Reporting
Authors: Woolever Donald R. 
Published: April 2021

ABSTRACT
Background: In response to the occurrence of a sentinel event—a medical error with serious consequences—Eglin U.S. Air Force (USAF) Regional Hospital developed and implemented a patient safety program called Medical Team Management (MTM) that was modeled on the aviation industry’s Crew Resource Management program and focused on communication, teamwork, and reporting.
Objective: To determine the impact of a patient safety program on patterns of medical error reporting.
Methods: This study was a retrospective review of 1,102 incident reports filed at Eglin USAF Regional Hospital in Florida between 1997 and 2001. Collected data from the comparison periods (1998 and 2001) was statistically analyzed using the chi-square test.
Results: The number of reports submitted increased significantly from 200 for 4,671 hospital admissions in 1998 to 276 for 4,003 admissions in 2001 (chi-squared = 28.38, P &lt; 0.0001). Evaluation of incident severity showed 172 (86 percent) near misses (no impact on patient) in 1998 and 251 (91 percent) in 2001. In 1998, there were 28 (14 percent) adverse events (patient minimally effected) and 25 (9 percent) in 2001 (chi-squared = 3.302, P = 0.069). Analysis by rank of person filing the report revealed 39 reports submitted by junior nurses and 11 submitted by junior enlisted personnel in 1998, while in 2001 those numbers increased to 75 and 24 reports, respectively (chi-squared = 6.554, P = 0.161).
Conclusion: This study indicates that, since the implementation of MTM, there has been a statistically significant increase in the number of reports filed at Eglin USAF Regional Hospital. Similarly, the severity of incidents shows an overall decline approaching statistical significance. Although there was an increase in reporting from junior team members, this was not statistically significant. These findings suggest that there have been changes in the patterns of error reporting since the implementation of MTM.
“Near-Miss” Reporting System Development and Implications for Human Subjects Protection

Published: April 2021

ABSTRACT
Background: Reviews of recent research-related fatalities have demonstrated clinical research system failures likely contributed to the event. Current research safety-reporting mechanisms focus on individual protocols and are therefore less likely to detect system-level failures. Methods: We have implemented the “near-miss” reporting system for a general clinical research center to detect latent failure within the research environment. Results: An identified research-related near miss includes a research volunteer being mistakenly directed into an incorrect protocol. Before beginning the incorrect study, the participant recognized the protocol did not coincide with the consent document and the error was detected without harm. Lack of both reliable research-participant tracking and verification programs was believed to be an important latent failure associated with the research unit. Discussion: Collecting research unit-specific information on potential safety concerns could identify system failures that might not be identifiable through traditional human subjects protection programs.
Detecting Sugarcane Crop Yield using Decision Tree Classifier in the District of Muzaffarnagar
Authors: Ankit Kumar  , Anil Kumar Kapil  
Published: April 2021

The district of Muzaffarnagar is the highest sugarcane producing district in Uttar Pradesh and therefore is an important industrial district as well. The district is part of Western UP and it shares the problems of the sugar industry elsewhere in the state: unpredictable demands and crop failures. In this context, predicting sugarcane demand and informing its production can turn to be just the key to solve some of the problems the industry faces.
The existing crop forecasting method for the cultivation of sugarcane used in UP relies, to a large degree, on subjective details, centred on the expertise of engineers in the sugar and alcohol field and on information on input demand in the supply chain. The measurement of the utility of the sample detection using NDVI images from the SPOT sensor used in the sensor's determination over the ECMWF model was possible to infer the official productivity data reported in the previously selected municipalities and harvest. Significant features of the municipal productivity of a given village is listed in a decision tree, and out of the combinations of attributes the corresponding municipal productivity is rated as "Normal" on the average urban productivity scale. Using data from the NDVI time-series between 2013 to 2020, we can discern the three classes of productivity in the meanwhile. Findings indicate that productivity in January ranked as less than mean, mean, and more than mean. The findings were more successful for the class Vegetation, the participants of which were permitted to conclude about the pattern of the average federal productivity prior to.
Optimization of Material Recovery Strategies in the Demolition Phase of Buildings – A Case Study

Published: April 2021

Globally, the construction industry is one of the most environmentally catastrophic industries, with a significant effect on the raw materials usage, their commitment of use throughout their whole life cycle, and the atmosphere in which they work. Between 1950 and 2010, global average material consumption rose from 5.0 t to 10.3 ton per capita per year, owing to population growth, industrialization, and increased socio-economic strength. Moreover, this industry uses 35% of produced energy and releases 40% of carbon dioxide into the Earth's atmosphere. One hundred fifty million tons of CDW is made in India according to the BMPTC, and less than 1% is reutilized properly added to that the 55% of total solid waste in India are from the construction industry. The waste produced during the demolition can be well utilized if managed and appropriately recovered, which directly reduces the virgin raw material usage in the new construction, decreasing the amount ending in the landfill. This study aims to understand the strategies and technology for material recovery after the building's life. The literature review will be taken up to list the different strategy in practice for material recovery. The techniques for material recovery are discussed to understand more in detail. This research helps find the other methods for material recovery and equipment and technology during the demolition and reconstruction of the RCC framed structure. The bottlenecks in the adoption of the various strategy are studied in this research.

Firm performance is fundamental to businesses considering its role in assisting organisations to realize their goals and achieve successes. Consumer goods manufacturing industry in Nigeria are experiencing decline in performance like profitability, market share, sales growth, competitive advantage, and productivity resulting from poor application of entrepreneurial orientation measures. This study examined the interaction between entrepreneurial orientation and market share of selected quoted consumer goods manufacturing companies in Nigeria.The study adopted cross sectional survey research design. The population of the study was 1,551of twelve (12) quoted consumer goods manufacturing companies in Nigeria. Total enumeration was used to sample the entire population. A self-developed structured and validated questionnaire was used for data collection. The Cronbach’s alpha ranges between 0.721 and 0.892. The response rate was 90.5%. Data were analyzed using descriptive and inferential statistics (Multiple and Hierarchical regression analysis).Findings revealed that entrepreneurial orientation components had significant influence on market share of selected quoted consumer goods companies in Nigeria (Adj. R2 = 0.791; F (5,441) = 339.129, p= 0.000). The study concluded that entrepreneurial orientation (innovativeness, competitive aggressiveness, proactiveness, risk-taking and planning flexibility) had significant effect on market share of selected quoted consumer goods companies in Nigeria and recommended that managers of selected quoted consumer goods manufacturing companies should practice entrepreneurial orientation ideologies to be able to be proactive and competitive enough to further boost the market portion of quoted consumer goods companies.
