A method for controlling the synthesis gas composition obtained from a steam methane reformer (SMR) that obtains its feedstock as product gas directly from a steam hydro-gasification reactor SHR). The method allows control of the H2 / CO syngas ratio by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR. The steam and methane rich product gas of the SHR is generated by means of hydro-gasification of a slurry of carbonaceous material and water. The mass percentages of the product stream at each stage of the process are calculated using a modeling program, such as the ASPEN PLUS™ equilibrium process. By varying the parameters of solid to water ratio and hydrogen to carbon ratio, a sensitivity analysis can be performed that enables one determine the optimum composition of the slurry feedstock to the SHR to obtain a desired syngas ratio output of the SMR. Thus one can adjust the hydrogen feed and the water content of feedstock into the SHR that supplies the SMR to determine the syngas ratio output of the SMR.

The invention provides, among other things, lyophilized compositions of high surface area that comprise a protein and that reconstitute quickly and efficiently to solution of high protein concentration with minimal formation, if any, of foam, effervescence, bubbles, turbidity, or particulates that might be deleterious. The invention also provides, among other things, methods for making the lyophilized compositions. The invention in additional aspects also provides Raman Imaging Spectrographic methods for real time analyses of polymorphs in a sample using PLS algorithms. By way of particular example, the use of the method for the analysis of mannitol polymorphs is described, and the use of the analysis to determine optimum compositions and lyophilization methods for producing lyophilates of pharmaceutical proteins having a predefined distribution of mannitol polymorphs and having the aforementioned reconstitution properties is also described.

In a method for manufacturing a piezoelectric actuator, the piezoelectric layer is formed by using material particles M having a composition which differs from an optimum composition by a diffusion amount of Ti. The piezoelectric layer has a two-layer structure including a first piezoelectric layer formed on a vibration plate and a second piezoelectric layer laminated on the first piezoelectric layer. Only the first piezoelectric layer has a composition different from the optimum composition, and the second piezoelectric layer laminated thereupon has the optimum composition. When the piezoelectric layer of such a two-layer structure is subjected to the annealing treatment, the composition of the first piezoelectric layer is corrected and becomes the optimum composition by the diffusion of a diffusion element. On the other hand, because the diffusion does not advance to the second piezoelectric layer which is on the farther side from the vibration plate, the optimum composition of the second piezoelectric layer is maintained.

The invention relates to methods and instruments for the rapid detection and rapid mass spectrometric identification of microbial infective agents in blood or other body fluids. The invention recognizes that blood is not a good environment for the cultivation of microbes and provides a method which (a) largely destroys or dissolves the human particles in body fluids, such as erythrocytes and leukocytes in blood, without impairing the ability of the microbes to reproduce, (b) separates the microbial pathogens from the fluid, (c) cultivates them in a nutrient broth which contains none of the antimicrobial components of the body fluids, (d) separates them from the nutrient broth, and (e) identifies the microbes by a mass spectrum of the microbial proteins. The dissolution of the human particles also releases the microbes nesting in macrophages. The cultivation in an optically clear nutrient broth with optimum composition not only accelerates the propagation of the microbes compared to all other cultivation methods, but also makes it possible to continuously measure their quantitative growth starting from a low microbe density. This firstly allows the mass spectrometric identification to be carried out at the earliest possible time, secondly provides a positive detection of microbes far ahead of their identification, which can be lifesaving for the patient; and thirdly makes it possible to start the determination of resistances early.

The present invention provides a class of thermotropic liquid crystalline polyesters (TLCPs) and molding compositions comprising the polyesters and glass fiber. The TLCPs consist essentially of repeat units derived from p-hydroxybenzoic acid (HBA), 6-hydroxy-2-naphthoic acid (HNA), terephthalic acid (TA), and hydroquinone (HQ), and the mole percent of HBA, HNA, TA and HQ is 34-72%, 12-26%, 4-21% and 4-21%, respectively. The TLCPs have a melting temperature equal to or below 355° C., an inherent viscosity of 4.0-10.0 dL / g and a Heat Deflection Temperature (HDT) in the range of 260-285° C. when compounded with 30% by weight glass fiber. The optimum compositions, selected from the above-mentioned compositional ranges exhibit a relatively low melting temperature and a relatively high HDT. Specified compositions, selected from the above-mentioned compositional ranges have low melting point, which are useful to blend with conventional polymers such as poly (ethylene terephthalate) and nylon etc.
