Carcel Flame Standard
No full textLamps of this type, designed by B.G. Carcel in 1800 to burn colza rapeseed oil, were used as prototype standards of luminous intensity at the Laboratoire Central d'Electricit in Paris in 1906. A clockwork pump supplied oil to the wick. Earlier comparisons with Violles proposed standard (based on the luminous intensity of 1 square centimeter of a platinum surface at its melting point) led to assigning a value of "9.6 bougies decimals" to such a lamp when burning at the rate of 42 grams per hour. The "bougie decimals" had been defined as 1/20 of a "Violle" and had about the same value as the British Parliamentary "candle."[H] 15.24 cm __[W] 15.24 cm __[D] 91.44 cm __Weight: 1.4 k
Term premium and quantitative easing in a fractionally cointegrated yield curve
No full textThe co-movement of US sovereign rates suggests a long-run common stochastic trend. Traditional cointegrated systems need to assume that interest rates are unit roots and thus imply non-stationary and non-mean-reverting dynamics. Based on recent econometric developments, we postulate and estimate a fractional cointegrated model (FCVAR) which allows for a mean-reverting stochastic trend. Our results point to the presence of such mean-reverting fractional cointegration among sovereign rates. The implied term premium is less volatile than the classic I(0) stationary and I(1) unit root models. Our analysis highlights the role of real factors (but not in flation) in shaping term premium dynamics. We further identify the dynamic effects of quantitative easing policies on our identified term premium. In contrast to the stationary-implied term premium, we find a significant term premium decline following these large-scale asset purchase programs

Modelamiento de un sistema de saneamiento básico usando el programa WaterGEMS en el centro poblado rural Carcel, La Libertad 2022
No full textLa presente investigación se realizó para el centro poblado rural Carcel, se realizó un modelamiento de sistema de saneamiento básico usando el programa WaterGEMS, para la realización de la tesis se utilizó un diseño no experimental debido a que consta de una sola variable y no existe una manipulación de aquella, es de tipo transversal descriptiva, el muestreo fue no probabilístico por conveniencia, la recolección de datos se realizó con la técnica de la Observación Directa y Encuesta, el instrumento utilizado fue la Hoja de Ficha de Datos y el Cuestionario, el problema es debido que el saneamiento básico en el centro poblado rural Carcel de La Libertad, los pobladores tienen una mala calidad de vida expuestos a enfermedades gastrointestinales y dermatológicas. Se realizó un modelamiento de un sistema de saneamiento básico para una población futura de 1477 habitantes, para un periodo de diseño de 20 años, el diseño de captación tiene un ancho de cámara de 1.10 m y una altura total de 1 m, para la línea de conducción se obtuvo una longitud total de 1.00 km, para la línea de aducción de 982.71 m, por último, para la red de distribución de 2.658 km
On the effect of ultrasound-assisted atmospheric freeze-drying on the antioxidant properties of eggplant
No full textThe low operating temperatures employed in atmospheric freeze-drying permits an effective drying of heat sensitive products, without any impairment of their quality attributes. When using power ultrasound, the drying rate can be increased, thus reducing the process duration. However, ultrasound can also affect the product quality. The aim of this study was to evaluate the effect of various drying process variables, namely air temperature and velocity, ultrasound power and sample size, on the antioxidant properties of eggplant (Solanum Melongena L.) samples. For this reason, drying experiments were carried out at different drying temperatures (-5, -7.5, -10 °C), power ultrasound levels (0, 25, 50 W; 21.9 kHz) and air velocities (2, 5 m s-1) using different sample sizes (8.8 mm and 17.6 mm cube side). The ascorbic acid content (Jagota and Dani method), total phenolic content (Folin-Ciocalteau method), and the antioxidant capacity (FRAP method) of the dried products were considered as quality indicators of the dried samples. The increase in air velocity and temperature, as well as the sample size, significantly reduced the antioxidant potential of the dried samples (p-value < 0.05). For a given sample size, the application of ultrasound, at the acoustic power levels tested, did not produce significant effects on the antioxidant indicators considered. Temperature measurements inside the drying sample showed a non-negligible temperature rise when acoustic power was applied

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
