    Notes: Abstract Excited72Ge projectiles are produced with 15MeV neutrons from a (d, t) fusion reaction, recoiling within a Ge(Li) detector. The relative response r of the detector on the kinetic energy released by those72Ge ions which are produced in a head-on collision was determined to be r=0.437±0.024 (for EGe=800 keV). This value is correlated to the ratio between nuclear and electronic energy loss.

    Description / Table of Contents: Zusammenfassung Die Reaktionsenthalpie der Reduktion des UO2F2 mit Wasserstoff wurde mittels quantitativer DTA bei linearer Aufheizung und bei isothermen Bedingungen gemessen und die thermodynamischen Daten des UO2F bestimmt, das als stabiles Zwischenprodukt bei der Reduktion des UO2F2 zum UO2 entsteht. Die Vorteile der isothermen DTA wurden auch bei der Reduktion des U3O8 zum UO2 demonstriert.
    Abstract: Резюме Энтальпия реакции во сстановления UО2F2 водородом была опред елена, исходя из количественных ДТ А измерений при линей ной скорости нагрева в из отермических условиях. Представле ны термодинамически е данные для UO2F, образующегося в кач естве стабильного промежу точного продукта в ре акции восстановления UO2F2 до UO2. Показаны преимущества изотер мического метода ДТА в реакции восстановления U3O8 до UO2.
    Notes: Abstract The enthalpy of the reduction of UO2F2 with hydrogen was obtained from quantitative DTA measurements with a linear heating rate and under isothermal conditions, and the thermodynamic data on UO2F, formed as a stable intermediate in the reduction of UO2F2 to UO2, are also presented. The advantages of isothermal DTA in the reduction of U3O8 to UO2 could be demonstrated.

    Notes: Summary The cloned ompA gene from Serratia marcescens was fully expressed in Escherichia coli and its product correctly assembled into the outer membrane. The S. marcescens polypeptide was not functionally equivalent to the E. coli OmpA protein, which serves as a phage receptor and as a component of several colincin uptake systems. DNA sequence analysis of the gene showed that three regions of the protein likely to be exposed on the cell surface not only differed extensively from the corresponding regions of the E. coli polypeptide but also from all other sequenced OmpA proteins. It is suggested that this sequence polymorphism represents a safety mechanism by which the various enterobacterial species can avoid cross-infection by noxious agents such as phages or colicins.
