cumin (cuminum cyminum) is an annual suitable for the dry and semi-dry areas of iran. recently, farmers have chosen to plant cumin because it requires less water and growth time. however, at harvest time, the resistance of cumin seed to shatter is low and, if careful attention is not paid to this fact, a major portion of the crop can be lost. when the connection force of the seed decreases, see...

We present a four channel optical add-drop multiplexer based on vertically coupled microring resonators fabricated in Si3N4/SiO2. The device with a Manhattan-like geometry has a footprint of 0.25 mm and can find application in metro-networks. The individual micro-resonators have a 50 μm radius and are thermally tunable over a 4 nm range. The maximum power consumption per ring is 0.5 W. Measurem...

We present experimental evidence that drop breakup is caused by thermal noise in a system with a surface tension that is more than 10(6) times smaller than that of water. We observe that at very small scales classical hydrodynamics breaks down and the characteristic signatures of pinch-off due to thermal noise are observed. Surprisingly, the noise makes the drop size distribution more uniform, ...

In concrete structures such as road facilities, harbor facilities, sediment control dams, and others, impact loads sometimes act directly on members. Load bearing capacity, toughness and displacement recovery properties are important, and should be evaluated appropriately. Recently, to prevent the spalling of concrete portions is also one of the important requirements for concrete structures. T...

OBJECTIVE The Japanese Respiratory Society (JRS) last revised the guidelines for community-acquired pneumonia (CAP) in adults in 2005. These guidelines proposed new criteria (A-DROP) to assess the severity of pneumonia and to differentiate between typical bacterial pneumonia and atypical pneumonia. The goal of the present study was to evaluate the utility of the A-DROP criteria for these descri...

The reduced core transport and the internal transport barrier (ITB) are observed after the ECRH is turned off in the HL-2A tokamak plasmas. It is found that the time delay of the central temperature afer ECRH switch-off increases as the ECRH deposition moves from center to edge. After the far off-axis ECRH switch-off (outside q=2 surface), the central temperature transiently increases for sever...
