Intraspecific variation in personality traits is increasingly recognized as an important determinant of invasion success and associated with the dispersal ability several invasive species. However, previous studies have focused on species through continuous habitats, despite high levels anthropogenic fragmentation modern environments. This study investigated how influences behaviour aquatic at ...

Abstract Silver Carp Hypophthalmichthys molitrix have expanded their range to encompass most of the Mississippi River basin, including much Missouri River. However, there is a paucity information concerning in especially tributaries. Little known about how function these tributaries or connectivity with main‐stem river can influence population demographics within either system. The Kansas tribu...

Evidence provided by Weir and Smith, particularly the findings from the National Health and Nutrition Examination Survey (NHANES), leads us to conclude that an increase in arthritis prevalence during the 1990s in the United States is probable, but the trend is likely overstated in the Health and Retirement Study (HRS). We show that a mistake in our earlier method does not change substantively o...

This work is mainly focused on improving the principle characteristics of RMPA. Here design of rectangular SRR based metamaterial structure is proposed, which has been superimposed on RMPA at a height of 3.2mm from its ground plane. The resonating frequency of the proposed antenna is 1.896GHz. Simulation results are suggested that the impedance bandwidth of RMPA with proposed metamaterial struc...

Nonlinear weirs are among the major structures used in water transfer. Thus, these have been subject of various studies. This study investigates effect flow splitters on discharge performance trapezoidal and triangular labyrinth one cycle. delves into effects installed crest one-cycle using numerical methods (Flow-3D) physical models. In model, two, four, or six vanes were placed at regular int...

M. k. Beirami and M. Ilaghi Hoseiny,

Forced hydraulic jump in a horizontal stilling basin with one and two continuous sills at the downstream end of an ogee standard weir was investigated. Experiments were completed on sills of five different heights which were fixed at two different distances from the toe of the weir. The main characteristics of the jump such as the sequent depth ratio, relative roller &#10length, and relative en...
