Descriptioninstrumentation allows for easy implementation as a loop powered transmitter, line powered analyzer, or portable battery powered unit within the same instrument.Effects of light spectrum on growth and stress response of 1. Introduction. Intensively reared fish may often be subjected to several chronic and acute stressors of endogenous (e.g. social interactions) or exogenous (e.g. unfavourable water quality, high densities, grading, handling) origin that may have detrimental effects on fish welfare and growth especially when imposed together (Huntingford et al., 2006).Water environment measuring system using ph sensorApr 10, 2014 · CONCLUSION The system's measurement capacity ranges from 0 to 80 C on water temperature, with an accuracy of 0.5 C and from 0 to 14 on pH value, with an accuracy of 0.05. Sensors applicable to different water quality could be installed at the node to meet the monitoring demands in different water environments and to obtain different parameters
Context. Tourism is becoming one of the largest and fastest growing industries in many countries. Increasing tourism exerts serious impacts on the habitats of wildlife in nature reserves.Aims. To ascertain how tourism affects the habitat of the Chinese giant salamander (Andrias davidianus), especially water quality and population size.Method. An experiment was conducted to investigate the Understanding N timing in corn yield and fertilizer N Early fertilizer nitrogen (N) application on cover crops or their residues during the off season is a practice adopted in Brazil subtropical conditions under no tillage corn (Zea mays L.) systems. However, the effect of early N application on yield, plant N content, and N recovery efficiency (NRE) for corn is not yet well documented. Five fertilizer N timings in an oat corn system were Understanding N timing in corn yield and fertilizer N Early fertilizer nitrogen (N) application on cover crops or their residues during the off season is a practice adopted in Brazil subtropical conditions under no tillage corn (Zea mays L.) systems.
