Abstract: An enhanced heat transfer device with electrodes is provided, which is applied to a heat exchanger with a plurality of fluid channels and includes a plurality of electrodes mounted in the fluid channels of the heat exchanger; a plurality of sensor units mounted in the fluid channels of the heat exchanger for measuring mass flow rates of fluids in the fluid channels; and a power source for providing voltage to the electrodes. The power source is used to drive the electrodes to produce turbulence to fluids passing through the fluid channels according to measured mass flow rates from the sensor units, so as to facilitate uniform fluid flows in the plurality of fluid channels and reduce effect of thermal boundary layer in the fluid channels to thereby enhance heat transfer performance for the heat exchanger.

Abstract: A shoe rack has two supports respectively and detachably mounted on top of the two elongated bases, a top tube detachably connected to free ends of the two supports via connectors and multiple shoe resting brackets sandwiched between the two supports. Each shoe resting bracket is adjustably connected to the two supports via a fixture which a first cutout, a second cutout, a first indentation defined in a side face defining the first cutout and a second indentation defined in a side face defining the second cutout. When the rods are received in the first cutout and the second cutout, the shoe resting bracket is tilted relative to a horizontal surface and when the two rods are received in the first indentation and the second indentation, the shoe resting bracket is parallel to the horizontal surface.

Abstract: The human HLJ1 tumor suppressor gene is herein defined as regulated by promoter, enhancer, and silencer regions. HLJ1 promoter activity and gene expression are inversely correlated with metastatic ability. HLJ1 is highly expressed, and inducible, in cells with low metastatic ability and expressed to a lesser extent in highly metastatic cells. HLJ1 gene expression suppressed the growth of human lung adenocarcinoma cells in vitro, and inhibited tumor growth in vivo. It also impeded the motility of human adenocarcinoma cells and reduced the anchorage-independent growth capacity and invasiveness of metastatic lung adenocarcinoma cells. The degree to which human lung adenocarcinoma patients express HLJ1 predicts their survival prognosis and their probability of relapse.

Abstract: A foot assembly includes two first legs each having a first ring provided with a first limiting recess defined in an inner face of the first ring and a first finger extending from the inner face of the first ring, two second legs each having a second ring and a second limiting recess defined in an inner face of the second ring to movably receive therein the first finger of the first ring and two joints each having a third ring, a tube and a tubular extension formed on a bottom rim of the third ring to extend into the first ring and the second ring. The joint has a second finger to be movably received in the first limiting recess such that the first leg is able to align with the second leg for storage.

Abstract: An adjustable garment rod includes a mounting bracket, an inner housing, a resilient element and a suspension arm. The mounting bracket has an arm slot and a first toothed ratchet surface and second toothed ratchet surface formed alongside the arm slot. The inner housing is mounted pivotally in the arm slot and holds the suspension arm. The suspension arm extends out of the arm slot and has two toothed protrusions. The resilient element presses the suspension arm so that the toothed protrusions engage the toothed ratchet surfaces to hold firmly the suspension arm at a given angular position. Further, the garment rod uses several simple parts so that assembling the garment rod is easy and quick, which saves costs and time.
