Pumps are designed and manufactured to operate well away from the cavitation condition and thus the factors affecting the onset of cavitation are important. A specially designed test rig was and constructed so that the onset of cavitation could be studied visually while obtaining actual NPSH data. The magnitude of the NPSH level at 3% drop in total discharge head of a pump was determined at dif...

this study represents an unusual case of mucormycosis localized in nasal cavity of a german shepherd dog. the patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. the dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. initial nasal rhinoscopy showed s...

[1] In this study, we investigate two-dimensional flow through a heterogeneous, semiconfined aquifer. In the presence of leakage the mean flow varies in space and the fluctuations of the flow become nonstationary spatially. Such a situation calls for a nonstationary stochastic approach since the classical stationary stochastic approaches are no longer appropriate. We make use of a nonstationary...

Exercise 3.2d: Calculate weights on hydraulic-head and flow observations For the head observations, first calculate the total variance of measurement error for the head observations, by adding the variance for the elevation measurement and the variance for the water-level measurement. This total variance is 1.0025 m, as shown in Table 3.2. Then, calculate the weight as the inverse of this varia...

Eye and head movements are coordinated during head-free pursuit. To examine whether pursuit neurons in frontal eye fields (FEF) carry gaze-pursuit commands that drive both eye-pursuit and head-pursuit, monkeys whose heads were free to rotate about a vertical axis were trained to pursue a juice feeder with their head and a target with their eyes. Initially the feeder and target moved synchronous...

 ABSTRACT Background: Nutrients meeting recommended dietary intakes take time to establish and once established are rarely maintained throughout hospital stay in preterm infants. Methods: Our purpose is to define the nutritional status and growth parameters of hospitalized patients at discharge in our hospital. Data were obtained concerning all 50 infants born weighing <1800 g and <34 weeks of ...

We propose a simple theory for the longitudinal profile of channels incised by groundwater flow. The aquifer surrounding the stream is represented in two dimensions through Darcy’s law and the Dupuit approximation. The model is based on the assumption that, everywhere in the stream, the shear stress exerted on the sediment by the flow is close to the minimal intensity required to displace a san...

Labyrinth weirs are utilized to transport a greater discharge during floods in contrast conventional due their increased weir crest length. Nevertheless, the geometric complexity of labyrinth weirs, determination accurate coefficients and accordingly, head-discharge ratings quite essential issues practical application. Hence, as first step present study proposes following eight standalone algor...
