Abstract The aim of this study was to determine the ornamental fish species affected by metacercariae digenean trematode Centrocestus formosanus and its distribution in 48 farms Morelos, central Mexico. parasite found form various numbers branchial cysts 11 25 analyzed. Goldfish Carassius auratus most commonly species; 20 30 were positive for parasite, showing severe clinical signs having a high mortality rate. For first time region, koi (a variant common carp Cyprinus carpio), zebrafish...

In this paper we present a theoretical study of small solar chimney. The dimensions the chimney channel are 1.95 m high, 1.70 wide, and 0.24 deep. has in its backside metallic plate as heat absorber, it is attached to concrete wall, which acts storage thermal insulation. On front part glass cover used decrease losses exterior. For study, steady-state energy balance equations were solved numerically for each element results showed temperature profiles cover, air inside channel, plate. Also,...

In recent years, opaque ventilated facades have been widely used as passive constructive elements, specially in warm climate areas. Considering their increasing relevance, the present article focuses on study of thermal and energy behaviour open joint façades (OJVF). The fluid flow has carried out by application 2D Particle Image Velocimetry (PIV) techniques to a facade model designed for laboratory measurements. this work, instantaneous time averaged velocity fields along cavity obtained...

This paper develops a method, based on the PASCOOL methodology, to evaluate empirically climatic representativeness of two Spanish locations in different meteorological zones: semi-arid and Mediterranean climates. New Typical Meteorological Years (TMYs) have been created using 10 years measurement principal variables. Different weighting factors for computed variables considered. The selected TMYs obtained minimizing standard deviation with reference databases studied considering final use...

This paper focuses on the thermal comparison between two full-size occupied buildings located in Madrid, built considering different constructive criteria. Hourly temperature distributions have been calculated during working timetable to assess indoor dynamic processes. In both cases there are less than 4% of outliers, reaching lower standard deviations bioclimatic offices. Temperature oscillations shown profiles depending user's behavior. High percentages neutral sensation and low values...

Model Predictive Control (MPC) is a key issue to deal with Net Zero Energy Buildings (NZEBs) and Communities. The application of an MPC scheme in buildings requires accurate building model weather forecast. How needs be forecast common question for applications. In this work comfort tracking problem solved through receding horizon Scheme. To take into account both solar gains thermal inertia second order state space assumed generic building. Scheme applied Almería's climate (South Spain)to...

Prior to construction, the simulation of thermal behaviour a building is mandatory in Spanish Building Technical Code. However, there are few post-occupancy studies for buildings use implying simulation. In this work, model developed at design stage Passive Solar fitted/calibrated from experimental measurements. work it also new methodology fitting context occupied buildings. A aspect link between and be fitted. This technique useful two ways. First, allows assessing relative impact priori...

High-dispersion time-resolved spectroscopy of the dwarf nova SS Cygni was obtained during two consecutive days at end an outburst. The emission lines present a double-peaked profile with peak-to-peak separation |$526 \pm 14\,\text{ km s}^{-1}.$| have complex structure which includes narrow asymmetric component coming from hot spot in accretion disc or chromosphere red dwarf. radial velocity analysis yields semi-amplitude values |$K_\text{em}=96 5\,\text{ s}^{-1}$| for wings Hγ and Hβ,...

Abstract. Land Surface Temperature (LST) is one of the important factors in monitoring urban climate. Observing variations LST can provide a better understanding Urban Heat Islands (UHI) phenomenon. The aim this research to assess relationship between spatial and temporal distribution water consumption Zamboanga City for years 2016 2017. Data from city’s district were used compute per capita (PCWC) 49 barangays. Landsat 8 data with 30m resolution computed using inverse Plank function other...

This paper reports the study of different aspects data based modelling, focusing on physical issues and considering a simplified case study. Different analysis approaches have been applied to several series recorded in test conditions. The results compared. effect solar radiation, relevance non- constant surface effects evaluated through an exploratory mono-dimensional analysis. Afterwards tri- dimensional has applied, estimate overall UA gA value building. robustness is studied comparing...

The USAF Test Pilot School (TPS) and the Air Force Research Laboratory (AFRL) have partnered with Lockheed Martin General Electric (GE) Global to execute first flight test using dual bimorph synthetic jet (DBSJ) actuators in order demonstrate effectiveness of active flow control technology. phase aeroelastic load (ALC) program demonstrated use small, electronically controlled DBSJ mitigate effects turbulent airflow. TPS flew three missions that were dedicated evaluating this technology a...

The ``Gamma Ray Astronomy at ALmeria'' (GRAAL) experiment uses 63 heliostat-mirrors with a total mirror area of ~ 2500 m2 from the CESA-1 field to collect Cherenkov light airshowers. detector is located in central solar tower and detects photon-induced showers an energy threshold 250 +- 110 GeV asymptotic effective detection about 15000 m2. Data sets taken period September 1999 - 2000 direction Crab pulsar were analysed for high gamma-ray emission. Evidence flux integral 2.2 0.4 (stat)...
