Perbedaan Efektivitas Zeolit Dan Manganese Greensand Untuk Menurunkan Kadar Fosfat Dan Chemical Oxygen Demand Limbah Cair “Laundry Zone” Di Tembalang

Laundry business is a business in clothes washing services. Preliminary test results show that the levels of phosphate and COD laundry liquid wastes is 12,36 mg/l and 5.920 mg/l. These levels exceeded the water quality standard of waste that phosphate concentration of 2 mg/l and COD concentration of 100 mg/l. This research aimed to determine the difference effectiveness of zeolite and manganese greensand to decrease phosphate and chemical oxygen demand on waste "laundry zone" in Tembalang. This research uses Quasi-Experimental with pretest - posttest design. The sample used is wastewater from the washing machine outlet of "laundry Zone". Analysis data used to test hypothesis is by one way anova test with 95% significance level. Research result show that phosphate levels before treatment is 12,36 mg/l and COD levels is 5.920 mg/l. After treatment with zeolite and manganese greensand in diameter 0,25 mm, 0,5 mm, 0,75 mm and 1 mm showed that the levels of phosphate and COD decreased. From one way anova got the difference at significant of α = 0,05 decreased levels of phosphate and COD after media zeolite by p-value = 0,001, the difference at significant of α = 0,05 decreased levels of phosphate and COD after media manganese greensand by p-value = 0,01, and the difference at significant of α = 0,05 decreased levels of phosphate and COD after media zeolit and manganese greensand by p-value = 0,0001. Effectiveness of the highest decline in phosphate and COD reached 73,30 % dan 71,68% occurred in treatment with zeolite diameter of 0,25 mm

Estratigrafía de alta resolución de depósitos de flujos gravitacionales de la Formación Los Molles (Grupo Cuyo - Jurásico) en la región de La Jardinera, cuenca Neuquina

El Grupo Cuyo en el área del arroyo La Jardinera (Pliensbachiano a Caloviano Temprano) refleja una fisiografía de cuenca de plataforma y talud. Una discordancia de orden mayor define la culminación de una espesa sucesión de turbiditas y representa un límite de secuencia de 2do orden. La más antigua secuencia de 2do orden comprende el tramo basal de la Formación Los Molles e incluye un ciclo transgresivo-regresivo asignado a estratos de base de talud y fondo de cuenca. La secuencia más joven, que incluye el resto del Grupo Cuyo, consiste de una sucesión regresiva puntuada por varios desplazamientos abruptos de elementos fisiográficos (límites de secuencia de 3er orden). Las secuencias depositacionales de 3er orden incluyen depósitos de talud y de base de talud del Aaleniano de la Formación Los Molles, facies de plataforma del Bajociano Temprano en la transición entre las formaciones Los Molles y Lajas, y sedimentitas de plataforma interna a nearshore del Bajociano medio a tardío de la Formación Lajas, que es a su vez cubierta por depósitos del Bathoniano aluvial de la Formación Challacó. Ciclos de más alta frecuencia alternan en la sucesión y han controlado el origen, depositación y abandono de los elementos arquitecturales. Análisis de facies y de elementos arquitecturales indican que los depósitos gravitatorios densos de la Formación Los Molles encuadran en un modelo de rampa submarina. Los tres tipos de flujos gravitacionales (GF) han sido relacionados a caídas del nivel del mar de 4to orden. Los GF1 fueron asignados a flujos hiperpícnicos producidos durante un cortejo temprano de mar bajo de 4to orden, coevo con incisión fluvial en la plataforma, que evolucionaran a flujos turbidíticos en el talud, produciendo cargas de pulsos depositacionales cuya signatura composicional es fluvial. El sistema de GF1 incluye canales relativamente pequeños sobre el talud, lóbulos bien desarrollados en la base del talud y la planicie de fondo de cuenca proximales, así como lóbulos adventicios en la planicie del fondo de cuenca. Los estratos GF2 fueron asignados a flujos hiperpícnicos influenciados por un componente oscilatorio y relacionados a cortejos tardíos de mar bajo de 4to orden, que también incluyen relleno de canales incididos. Ellos están caracterizados en el talud por areniscas onduladas y laminadas ampliamente distribuidas y facies heterolíticas, que incluyen scours de bajo relieve en sus porciones centrales. Ellos representan flujos densos más diluidos y de grano más fino con respecto a los GF1. Los GF3, también asociados con cuñas de mar bajo de 4to orden, comprenden depósitos de flujos en masa y debris de talud y de base de talud, que representan clásicos surges de corta duración causados por debilidades en taludes relativamente abruptos. Los cortejos transgresivos y de mar alto de 4to orden llevaron al abandono de la etapa turbidítica y extensiva depositación de fango.The Pliensbachian to Early Callovian Cuyo Group in the Arroyo La Jardinera area reflects a shelf-slope-basin plain physiography. A major unconformity defines the onset of a thick turbidite succession and represents a 2nd order sequence boundary. The older 2nd order depositional sequence comprises the base of Los Molles Formation and includes a transgressive-regressive cycle ascribed to basin plain and slope rise strata. The younger one, which includes the rest of the Cuyo Group, consists of a regressive succession punctuated by several abrupt shifts of physiographic elements (3rd order sequence boundaries). The 3rd order depositional sequences include Aalenian slope rise and slope deposits in the Los Molles Formation, Early Bajocian shelfal facies at the transition of the Los Molles and Lajas formations, and Middle to Late Bajocian inner shelf to nearshore strata in the Lajas Formation that are overlain by Bathonian alluvial deposits of the Challacó Formation. Higher frequency cycles punctuate the succession and have controlled the origin, deposition and abandonment of the architectural elements. Facies and architectural elements analyses indicate that gravity flow deposits in the Los Molles Formation fit in a submarine ramp model. The three identified gravity flow (GF) types have been related to 4th order relative sea-level falls. The GF1 was ascribed to hyperpycnal flows produced during 4th order early lowstand, coeval to fluvial incision on the shelf, which were ignited in the slope and produced depletive depositional pulses with a fluvial compositional signature. The GF1 system includes relatively small channels in the slope, well-developed lobes in the slope rise and proximal basin plain, and lobe fringes in the basin plain. The GF2 strata were ascribed to hyperpycnal flows influenced by an oscillatory component and related to the 4th order late lowstand systems tract that also includes the incised channels fill. They are characterized in the slope by widespread, undulating and laminated sandstone and heterolithic facies, which include low relief scours at their central portions. They represent more diluted and finer-grained density flows relative to the GF1. The GF3, also associated with the 4th order lowstand wedge, comprises mass and debris flow deposits in the slope and slope rise that represent classical, short-lived surges caused by slope failures on relatively steep slopes. The 4th order transgressive and highstand systems tracts led to the abandonment of the turbidite stages and widespread mud deposition.Fil: Paim, Paulo S. G..

The aim of the ArDM project is the development and operation of a one ton double-phase liquid argon detector for direct Dark Matter searches. The detector measures both the scintillation light and the ionization charge from ionizing radiation using two independent readout systems. This paper briefly describes the detector concept and presents preliminary results from the ArDM R&D program, including a 3 l prototype developed to test the charge readout system.Comment: Proceedings of the Epiphany 2010 Conference, to be published in Acta Physica Polonica

Study of the eightfold degeneracy with a standard β\beta-Beam and a Super-Beam facility

The study of the eightfold degeneracy at a neutrino complex that includes a standard $\beta$-Beam and a Super-Beam facility is presented for the first time in this paper. The scenario where the neutrinos are sent toward a Megaton water Cerenkov detector located at the Fr\'{e}jus laboratory (baseline 130 Km) is exploited. The performance in terms of sensitivity for measuring the continuous ($\theta_{13}$ and $\delta$) and discrete (${sign} [ \Delta m^2_{23} ]$ and ${sign} [\tan (2\theta_{23}) ]$) oscillation parameters for the $\beta$-Beam and Super-Beam alone, and for their combination has been studied. A brief review of the present uncertainties on the neutrino and antineutrino cross-sections is also reported and their impact on the discovery potential discussed

Electron/pion separation with an Emulsion Cloud Chamber by using a Neural Network

We have studied the performance of a new algorithm for electron/pion separation in an Emulsion Cloud Chamber (ECC) made of lead and nuclear emulsion films. The software for separation consists of two parts: a shower reconstruction algorithm and a Neural Network that assigns to each reconstructed shower the probability to be an electron or a pion. The performance has been studied for the ECC of the OPERA experiment [1]. The $e/\pi$ separation algorithm has been optimized by using a detailed Monte Carlo simulation of the ECC and tested on real data taken at CERN (pion beams) and at DESY (electron beams). The algorithm allows to achieve a 90% electron identification efficiency with a pion misidentification smaller than 1% for energies higher than 2 GeV
