Abstract: A cold energy recovery apparatus for a self-powered data centre is disclosed. The apparatus comprises a fluid storage tank having at least a pair of inlet and outlet, the inlet configured to receive a coolant; and a heat exchanger arranged in the tank, the heat exchanger having a pair of inlet and outlet, the inlet configured to receive liquefied natural gas. The apparatus is operable to permit the coolant to flow from the inlet to the outlet of the tank causing the coolant to be in fluid contact with the heat exchanger, in which the coolant is progressively cooled to a lower temperature by heat transfer to the liquefied natural gas via fluid contact with the heat exchanger. The liquefied natural gas is vaporized into natural gas due to the heat transfer and is directed out from the outlet of the heat exchanger.

Abstract: The invention relates to an arrangement of one or more cryogenic tank containers for storing liquefied natural gas (LNG) or compressed natural gas (CNG) on an open deck of a tugboat. The one or more cryogenic tank containers are removably mounted on and at an aft deck area of the tugboat and are provided with means for supplying LNG or CNG to the engine of the tugboat.

Abstract: A biopsy needle consisting of a main portion, a linking portion and a front end portion wherein the main portion has a first bore of uniform circular cross-section, the front end portion has a smaller second bore of uniform circular cross-section and the linking portion has a shoulder between the first bore and the second bore. The outer surface of the linking portion is tapered. The open front end has multiple projecting teeth which serve to cut. There may also be serrations on the outer surface of both the front end portion and the linking portion. The biopsy needle has slits or holes to facilitate the expansion of the captured biopsy specimen and to inject cement for bone support. The needle assembly has a non-slip grip on multiple surfaces and pins hold components in place during rotation of the assembly.

Abstract: A method and apparatus for injecting supportive and therapeutic agents into bone marrow. During conventional chemotherapy for leukemia, lymphoma, multiple myeloma and other bone related diseases, chemotherapeutic agents are typically injected intravenously. Intravenous injection, however, as a method of chemotherapy, has a number of potential disadvantages. By injecting therapeutic agents directly into the bone marrow using the present method and apparatus, these disadvantages can be avoided. A stronger needle with a shorter and sharper tip, when compared to a conventional intravenous or sternal puncture needle, designed to optimally administer therapeutic agents into bone marrow without causing injury is disclosed. The method includes injecting therapeutic agents into large reservoirs of bone marrow in accessible areas such as ilium and sternum is most likely to have a significant effect in treating bone marrow diseases.

Abstract: This invention relates to an integrated heavy lift and logistics vessel for receiving another vessel. Further the integrated heavy lift and logistics vessel is able to provide logistical support to the other vessel in remote locations. More particularly, this invention relates to an integrated heavy lift and logistics vessel that is designed to carry out heavy lifting and logistic supply functions in a stable manner. The integrated heavy lift and logistics vessel is also equipped with safe refuge quarters, helipad(s), various forms of storage, and areas for storage.

Abstract: An injection port system for placement in or on an individual includes a first port (55) defining a first injection chamber (58) with a septum (59), and a tubular securing device (38) for securing said first injection chamber to bone (52) of the individual. A needle inserted through the septum (59) enables material to be injected into or removed from the bone marrow (60), for example injecting chemotherapeutic agents, or stem cells, or withdrawing bone marrow for analysis. The injection port system (50) also comprises a second port (62) defining a second injection chamber (65) with a septum (66), the first port (55) being mechanically connected to the second port (62). The second port (62) is linked by a catheter (68) to a blood vessel, so that therapeutic fluids can be directly supplied to the blood system, and blood samples can be taken for monitoring.

Abstract: A method of synthesizing air-stable nano-scale zero-valent iron (NZVI) particles at room temperature is provided. Also, a method of treating environmental pollutants using nano-scale zero-valent iron synthesized by the above method is provided. According to the method, air-dried NZVI is very effective in removing pollutants such as arsenic, and the method is simple, cost-effective, environmentally friendly, and can stabilize the NZVI in air for more than 10 months.

Abstract: A method (200) for determining various bit failure modes in a static random access memory device. A hard/soft bit failure test sequence is performed on each cell of the memory device to determine whether the cell exhibits a hard bit failure or a soft bit failure, then a data retention test is performed on the cell having soft bit failure to determine whether the cell exhibits a data retention failure. A write or disturb test sequence is then performed on the cell not having data retention failure, and a read or disturb test sequence is performed on the cell having write or disturb failure. Finally, a disturb test sequence is performed on the cell having read or disturb failure, and then an analysis is performed on the data from the tests to determine whether the cell exhibits one of a write, read, or disturb failure.

Abstract: A needle for use in taking a bone marrow biopsy comprises a hollow tube having a front end portion formed to a reduced diameter by swaging. The front end is tapered by means of a number of circumferentially-spaced facets, forming a cutting edge. A tapering transition portion, between the main portion of the hollow tube and its reduced-diameter front end portion, is formed with a series of flutes which help in the needle cutting through the cortical bone. A spacer is provided for use in pushing the sample rearwardly out of the hollow tube, the spacer having a through-passage through which a trocar needle is passed and serving for accurate alignment of the distal ends of the hollow tube and trocar needle.
