岩石龟裂系数法在火山岩裂缝储集层预测中的应用

 本文针对辽河东部凹陷油燕沟中生界火山岩的具体特征，采用纵波波速的比值——“龟裂系数”裂缝分析法［1,2,3］，研究了火山岩裂隙发育程度。综合龟裂系数裂缝分析及其他方法发现，该区中生界火山岩有效储集层的测井相特征主要表现为低密度、低中子、高声波时差和高伽马值等特征。此法的关键在于根据不同火山岩的岩性，选用合适的岩石骨架参数，在此基础上利用测井约束地震反演计算火山岩的层速度，进而计算出龟裂系数，然后根据已钻至火山岩井孔的测井相特征编制出火山岩预测厚度图。     

Qualit?tssicherung bei Gemüse am Beispiel von Erzeugergro?m?rkten

Durch ein von Erzeugern und Vermarktern getragenes regionales Qualit?tssicherungsprogramm bei Gemüse konnten H?chstmengenüberschreitungen innerhalb von 5 Jahren um vier Fünftel gesenkt und entsprechend die Verkehrsf?higkeit der vermarkteten Partien erh?ht werden. Durch eine optimal organisierte Probenahme bereits vor der Ernte und Analytik innerhalb von zwei Tagen waren nicht vermarktungsf?hige Partien rechtzeitig zu erkennen. Die Nutzung der Analysenergebnisse als Beratungsinstrument durch Markt, Erzeuger und Beratung haben zu diesem Erfolg geführt.     

Solubilization of fish muscle proteins with buffers containing sodium dodecyl sulfate

Summary The extraction of fish muscle protein using SDS containing solubilization buffers was studied varying the time and the temperature of solubilization, as well as pH and SDS concentration of the buffer. At pH < 6 the myofbrillar proteins were incompletely solubilized; temperatures of 80-100 °C resulted in protein degradation observable in the SDS-PAGE.Samples of fish muscle containing high amounts of formaldehyde (50 mmoles FA/kg wet weight) could only be solubilised at 100 °C; on the other hand it was possible to solubilize cooked and/or canned products under mild conditions (2% SDS, 1% 2-ME, pH 8.9, shaking for 2 h at 60 °C).

Solubilisierung von Fischmuskelproteinen durch Natriumdodecylsulfathaltige Puffer

Zusammenfassung Der Einfluß von Solubilisierungszeit und -temperatur, des pH-Wertes und der SDS-Konzentration des Solubilisierungspuffers auf die Extraktion von Fischmuskelproteinen wurde überprüft. Bei pH-Werten < 6 wurden die myofbrillären Proteine nur unvollständig gelöst; Solubilisierungstemperaturen von 80 bis 100 °C führten zu einem in der SDS-PAGE sichtbaren Proteinabbau. Fischmuskelproben mit hohem Formaldehydgehalt (50 mmole FA/kg Feuchtgewicht) ließen sich nur bei 100 °C vollständig solubilisieren; demgegenüber gelang die weitgehende Solubilisierung gegarter und/oder sterilisierter Produkte unter milden Bedingungen (2% SDS, 1% 2-ME, pH 8,9; 2stündiges Schütteln bei 60 °C).

Automatic labeling and characterization of objects using artificial neural networks

Existing NASA supported scientific databases are usually developed and managed by a team of database administrators whose main concern is the efficiency of the databases in terms of normalization and data search constructs. The populating of the database is usually done in a manual fashion by row and column as the data become available, and the data dictionary is usually defined by the same team (at times with little input from the end science user). This process is tedious, error prone and self-limiting in terms of what can be described in a relational Data Base Management System (DBMS). The next generation Earth remote sensing platforms [i.e., Earth Observing System (EOS)] will be capable of generating data at a rate of over 300 Megabits per second from a suite of instruments designed for different applications. What is needed is an innovative approach that creates object-oriented data-bases that segment, characterize, and catalog, and are manageable in a domain-specific context, and whose contents are available interactively and in near-real-time to the user community. This paper describes work in progress that utilizes an artificial neural net approach to characterize satellite imagery of undefined objects into high-level data objects. The characterized data is then dynamically allocated to an object-oriented database where it can be reviewed and accessed by a user. The definition, development, and evolution of the overall data system model are steps in the creation of an application-driven knowledge-based scientific information system.     

Dynamics of cracked hollow beams

The finite element method with normal quadrilateral plate elements is used for the determination of the bending compliance of orthogonal full and open hollow section beams with transverse cracks. Computed results are compared with those from theory for the full rectangular sections and with experiments performed with rectangular hollow sections. The effect of such cracks on the dynamic response of channel-section beams is investigated. Such analysis is of importance for the identification of cracks in steel structures.     

The use of doped polyaniline as an electrode in the galvanic anodic protection of ferrous metals in industrial acid solutions

In order to investigate the galvanic anodic protection (GAP) of ferrous metals (such as 410, 304 and 316 stainless steels) in acid solutions by doped polyaniline (PANi), separate doped PANi powder-pressed electrodes with different surface areas (the area ratio of the PANi electrode to stainless steel is between 1:1 and 1:2) have been prepared. These were coupled with ferrous metal in the following solutions: 5 M sulphuric acid, 5 M phosphoric acid and industrial phosphoric acid (containing 5 M phosphoric acid and 0.05% chloride ion) to construct a galvanic cell, in which PANi is cathode while ferrous metal is anode. The results indicate that a PANi electrode with sufficient area can provide corrosion protection to stainless steel in these acidic solutions. A pilot scale coupling experiment was carried out. The results indicate that PANi is a promising material as an electrode for the anodic protection of ferrous metals in acidic solutions in industrial situations.
