摘要： This disclosure relates to an annular centrifugal extractor with Solid Separation Part to Separate Solid Particles Present in Solvent Extraction Fluid. In order to remove solid particles from the solution, a solid separation part/rotating bowl is attached to rotating bowl in such a way that solid particles settle inside the solid separation part. This solid separating centrifugal extractor contains two parts: (I) upper part which acts as a liquid-liquid separator to separate aqueous and organic solution used in solvent extraction operation and (II) bottom part which acts as a solid separator to separate solid particle present in solvent extraction liquids. The bottom rotating rotor is coupled with upper rotating rotor by threading arrangement. Both the rotating rotors are confined within a stationary cylinder. Dispersion with solid particles entering inside the rotating bowl is deflected towards the wall of the rotating cylinder by deflecting baffle by centrifugal sedimentation.

摘要： The present invention applies to a deuterated derivative of 3,3′-diselenodipropionic acid (D-DSePA), an organo-selenium compound and method of synthesis thereof. The invention also provides the method including D-DSePA for the inhibition of the proliferation of human non-small cell lung carcinoma (NSCLC) cells. This compound inhibits the proliferation of A549, H1975 and H3122 cells of NSCLC origin at a much lower concentration than that needed to inhibit the growth of non-cancerous lung fibroblast cells (WI-38 and WI-26 VA4). Further, D-DSePA exhibits additive effect in A549 lung cancer cells while protecting non-cancerous WI38 cells from radiotoxicity.

摘要： A method of treatment of disease condition resulting from deficiency of hematopoietic stem and progenitor cells and/or epidermal stem cells in skin comprising: administering to the subject suffering from said disease conditions, an effective amount of Jack bean lectin or a pharmaceutically acceptable salt thereof for increasing the abundance of hematopoietic stem cells and progenitor cells in bone marrow and/or epidermal stem cells in skin in vivo. Method of treating said conditions in a subject involves administering a single injection of lectin in a dose range of 0.5-2.0 mg/kg body weight to mouse leading to 2.815 to 3.55 fold increase in the abundance of epidermal stem cells in skin and a dose range of 8.0-10.0 mg/Kg body weight to a mouse leading to 2.36 to 6.67-fold increase in the abundance of hematopoietic stem and progenitor cells in bone marrow.

摘要： This invention relates to a sensor device consisting of long period gratings made of rare-earth doped double clad fiber, which is written by CO2 laser irradiation while the fiber is held static, for gamma dose measurement in the range of 150 Gy-2.5 kGy, extendable to 20 kGy, which measurements are real-time and can be from remote locations. The sensor device has high wavelength dip shift sensitivity of at least 2.8 nm/kGy, and its radiation-induced changes are near permanent. The gratings demonstrate negligible temperature sensitivity and the shifts recorded show negligible annealing at room temperature.

摘要： A system for on-line detection of incipient cracks in turbine blades to serve as early warning system for turbine blade failure. The system of non-intrusive detection of turbine blade condition of the invention is simple and cost effective and would enable assessing the health of the turbine blade during plant operation, which is extremely important for the safe operation of the turbine in an operating power plant. The present method and system of identifying the presence of modulated blade passing frequency (BPF) for blade vibration that is not correlatable to the change in the operating condition and would thus be indicative of presence of cracked blades with incipient cracking. It is capable for verifying the Campbell diagram and ascertain the margin available between the natural frequency of the blade/stage and the steam excitation frequencies/engine orders.

摘要： The novel lipophilic metal extractants of the class dialkyldiaza-tetraalkyloctanediamide (DADA) useful to selectively separate trivalent americium (sup. 241 Am) from trivalent lanthanides are represented by the formula 1: Wherein R is a C1 to C5 normal alkyl and R′ is a C4 to C8 normal and branched alkyl group. The compounds are synthesized at high yield and purity by the reaction of corresponding N,N′-dialkylethylenediamine and N,N-dialkyl-2-chloroacetamide. The separation is achieved by utilizing the soft-soft interaction between the trivalent actinides and ‘N’ atoms of the extractant. Both soft donor “n” and hard donor ‘O’ sites are incorporated in the molecule for better extraction of trivalent actinides over trivalent lanthanides. Thus, this molecule can be used as selective extractant to separate trivalent actinides from trivalent lanthanides.
