    Notes: In this paper we investigate the effects of post-bid defence activity for a sample of takeover bids in the UK. We find that most of the defences investigated promote the interests of target managers by significantly lowering the probability of bid success. We also find that most of the defences promote the interests of shareholders by increasing wealth gains by an amount that varies between 9% and 14%. These results suggest that bid resistance is to the mutual benefit of the managers and shareholders of target firms. This conclusion is in line with recent developments in agency theory.

    Notes: The detailed dynamic simulation of coupled process units in chemical plants is gaining an increasing importance as a useful tool in plant engineering and operation. The outline of the program package DIVA (Dynamische Simulation verfahrenstechnischer Anlagen) which is currently under development is presented in the following. The dynamic plant equations and the corresponding Jacobian matrix are generated automatically. The full exploitation of sparse matrix techniques in combination with stiff ODE (ordinary differential equation) solvers allows an efficient solution of all the equations simultaneously. The possibilities offered by the simulator are demonstrated by the simulation of two laboratory plants.

    Description / Table of Contents: Synthesis and Structure of Cyclic Alkoxy(tetraalkyl)phosphoranes and -arsoranesFrom the reaction of trimethyl and triethyl methylenephosphoranes and -arsoranes resp., (1,2λ5-oxaphospholanes or -arsolanes, resp.), are obtained. According to variable temperature 1H, 13C and 31P n. m. r. spectra, these compounds can be assigned a trigonal-bipyramidal structure, with an alkyl group and an oxygen atom in axial positions.
    Notes: Aus Trimethyl - und Triäthyl(methylen)phosphoran und Trimethyl(methylen)arsoran werden mit äquimolaren Mengen Äthylenoxid cyclische Alkoxy(tetraalkyl)phosphorane bzw.-arsorane (1,2λ5-Oxaphospholane bzw. -arsolane) erhalten.  -  Nach1H-, 13C-und 31P-NMR-spektroskopischen Studien bei variabler Temperatur kommt diesen Verbindungen trigonal-bipyramidale Struktur mit einer Alkylgruppe und einem Sauerstoffatom in dem axialen Positionen zu.

    Description / Table of Contents: Oxirane and Oxetane Cleavage with Phosphorus Ylides: A Pathway to Fluctuating Mono- and Spirobicyclic Phosphoranes1-Methyl-1-methylen-1 λ5-phospholane (1) and -phosphorinane (3) react with oxirane under mild conditions to form the spirobicyclic phosphoranes 2 and 4, resp., in high yields. Oxetane converts the same ylides into the corresponding heterocycles 6 and 7 only at elevated temperatures and under autogenic pressure in sealed tubes. Similarly, trimethylmethylenephosphorane inserts into oxetane with formation of the monocyclic 2,2,2-trimethyl-1,2λ5-oxaphosphorinane (5).  -  A detailed variable temperature NMR study leads to trigonal bipyramidal ground state geometries of the phosphoranes 2 and 4-7. Their fluctuating behaviour, for which any irregular process could be excluded, is most easily described by the turnstile model of pseudorotation. The compounds reported appear to be the most simple cyclic systems of the type R4POR′ available to date.
    Notes: 1-Methyl-1-methylen-1λ5-phospholan (1) und -phosphorinan (3) reagieren schon unter milden Bedingungen mit Oxiran in guten Ausbeuten zu den spirobicyclischen Phosphoranen 2 bzw. 4. Oxetan verwandelt die gleichen Ylide in die entsprechenden Heterocyclen 6 und 7, jedoch erst bei höherer Temperatur und unter Eigendruck im Bombenrohr. Trimethylmethylenphosphoran wird in ähnlicher Weise in den Oxetanring eingeschoben, wobei das monocyclische 2,2,2-Tri-methyl-1,2Δ5-oxaphosphorinan(5)entsteht.  -  Ein detailliertes Studium der temperaturabhängigen NMR-Spektren führte zu einer trigonal-bipyramidalen Grundzustandsgeometrie der neuen Phosphorane 2 und 4-7. Deren fluktuierendes Verhalten, für das irreguläre Prozesse ausgeschlossen werden konnten, ist am leichtesten unter Zuhilfenahme des Turnstile-Modells zu beschreiben.

    Notes: Simulators for support of process and plant management. Process simulators are increasingly used for plant and process operation purposes. These simulators differ from those used in process design in the user interface, which is identical to the usual operator interface of distributed control systems. The progress of the numerical solution parallels the dynamic behaviour of the real process, and not that of the numerical procedure. The simulation-supported tasks of plant and process operation are: education of operators, training and instruction of operators, support of plant operation by interpretion of plant states and transitions and by helping to formulate operating instructions. These tasks, the available simulation concepts and examples are discussed in detail.

    Notes: Dynamic simulation of complex chemical processes. The detailed dynamic simulation of coupled process units in chemical plant is gaining increasing importance as an important tool in plant engineering and operation. This paper deals with basic problems in the development of a universally applicable dynamic simulator. General requirements are formulated. The program package DIVA currently under development is outlined. Simulation of the start-up phase of a simple production plant as an example demonstrates the mode of functioning and the potential of the simulator. Future work will concentrate on enlarging the model libraries and on increasing the efficiency and ease of use to meet the demands of industrial applications.
