River Region of Baru-Kluet has a steep slope contour and high rainfall so that it is vulnerable to flooding while during the dry season rice fields experience drought due lack water. Therefore, dam built mitigate these issues. The spillway flow-control component in which used improve regulation enlarge flow rate will cross building. Spillway hydraulic behavior called cavitation. experiment was ...
[1] High‐speed video images of eight branches of a lightning stepped leader recorded at a frame rate of 300 kiloframes per second (kfps) (3.33 ms exposure) are analyzed, representing the fastest published frame rate measurements of stepped leader stepping by about 1 order of magnitude and the first observations of space stems/leaders associated with stepped leaders. Sixteen occurrences of space...
The Performance of shooting pool, in addition to the quality of the area in which the flow collides with it, depends to the height of the jet drop, the angle of the water flow, the depth of the jet and the concentration of the jet. By increasing the height of the jet drop, the fall velocity increases and subsequently the jetchr('39')s energy will be more intrusive. Different collision area from...
Designing a stepped wedge trial: three main designs, carry-over effects and randomisation approaches
BACKGROUND There is limited guidance on the design of stepped wedge cluster randomised trials. Current methodological literature focuses mainly on trials with cross-sectional data collection at discrete times, yet many recent stepped wedge trials do not follow this design. In this article, we present a typology to characterise the full range of stepped wedge designs, and offer guidance on sever...
BACKGROUND Depression in women is one of the commonest problems encountered in primary care. We aimed to compare the effectiveness of a stepped-care programme with usual care in primary-care management of depression in low-income women in Santiago, Chile. METHODS In a randomised controlled trial, in three primary-care clinics in Chile, 240 adult female primary-care patients with major depress...
Atmospheric gas saturation levels were monitored throughout a 40-km reach of the upper Colorado River during the summer and fall of 1995 to identify possible sources of gas supersaturation in the river. Gas saturation data from seven fixed sampling points and 40 random sampling points were analyzed using analysis of variance (ANOVA) and multiple regression methods. The lowest total gas saturati...
Abstract Otolith strontium:calcium ratios were used to trace lifetime movements of American eels (Anguilla rostrata) captured in salt-water bays and adjoining freshwater ponds in Prince Edward Island, Canada. Eels were classiWed into migratory contingents based on their movement patterns. A pond with a pool-and-weir salmonid Wshway and a pond drained by a low-gradient channel contained eels tha...
