Methods of fabrication of a thermoelectric module from thin film thermoelectric material are disclosed. In general, a thin film thermoelectric module is fabricated by first forming an N-type thin film thermoelectric material layer and one or more metallization layers on a substrate. The one or more metallization layers and the N-type thin film thermoelectric material layer are etched to form a number of N-type thermoelectric material legs. A first electrode assembly is then bonded to a first portion of the N-type thermoelectric material legs, and the first electrode assembly including the first portion of the N-type thermoelectric material legs is removed from the substrate. In a similar manner, a second electrode assembly is bonded to a first portion of a number of P-type thermoelectric material legs. The first and second electrode assemblies are then bonded using a flip-chip bonding process to complete the fabrication of the thermoelectric module.

Methods and compositions useful for neuronal protection in retinal cells in vitro and the protection of mammalian cells from reactive oxygen species in vivo are provided. UltrafÊne nano-size cerium oxide particles, less than 10 nanometers in diameter, have been provided to decrease reactive oxygen species (ROS) in retina tissue that generates large amounts of ROS. These reactive oxygen species (ROS) are involved in light- induced retina degeneration and age-related macular degeneration (AMD). Cerium oxide nanoparticles have been used to promote the lifespan of retinal neurons and protect the neurons from apoptosis induced by hydrogen peroxide in vitro and in vivo. The neuronal protection in retinal cells is achieved by decreasing generation of intracellular reactive oxygen species (ROS). Thus, cerium oxide particles are used to promote the longevity of retinal neurons in vitro and mammalian cells in vivo.
摘要:
A method of compacting a roadway section includes entering initial input parameters into a compaction analyzer, A plurality of passes is made with a roller over a portion of the roadway section and vibratory energy is applied thereto. Responsive vibration signals are gathered and the compaction analyzer generates estimated density signals. Actual density measurements are taken and the estimated densities are compared thereto. Selected ones of the initial input parameters are adjusted so that an adjusted density output signal which represents the actual density of a roadway section is generated.
摘要:
The invention provides a method for aiding in the diagnosis of irritable bowel syndrome (IBS), said method comprising the steps of: (a) measuring the level of a cytokine within a sample previously obtained from a patient using an assay system or assay device; (b) comparing the measured cytokine level of the sample with a pre-defined level of the cytokine found in normal or inflammatory states; (c) determining if the patient has IBS based on the comparison in step (b); and (d) reporting the determination to the patient or a clinician.
摘要:
A novel clostridia bacterial species (Clostridium ragsdalei, ATCC BAA-622 and/or PTA-7826, 'P11') is provided. P11 is capable of synthesizing, from waste gases, products which are useful as biofuel. In particular, P11 can convert CO to ethanol. Thus, this novel bacterium transforms waste gases (e.g. syngas and refinery wastes) into useful products. P11 also catalyzes the production of acetate.
摘要:
A light surface display for providing a three-dimensional image including a plurality of particles suspended within a volumetric display. A first projection system projects sequential slices of electromagnetic energy of one or more wavelengths along the length and width of the volumetric display energizing particles to form a two-dimensional image. A second projection system projects translational slices of electromagnetic energy of one or more wavelengths that intersect with the energized particles across the depth of the volumetric display. A control system synchronizes the projection of the image source and the activation source such that the two-dimensional image and the translational slices energize the particles for a pre-determined length of time so that the particles illuminate to form an illuminated three-dimensional image.
