Abstract

Stephen Porges’s polyvagal theory proposes to integrate various scientific disciplines such as anatomy, physiology, psychophysiology, evolutionary and developmental biology, social sciences and psychotherapy together with special evolutionary features of the vagus nerve in mammals putatively claimed by polyvagal conjectures. This specifically involves linking neuroanatomical hypotheses about the vagus nerve with social and psychological concepts, especially regarding socioemotional behavior and conditions of extreme stress. These concepts have particularly found increasing popularity among trauma therapists, and have sometimes been described as groundbreaking, as in the last issue of this journal (Ackermann, 2024; Grassmann, 2024; Rahm & Meggyesy, 2024). However, there is a broad state-of-the-knowledge consensus among experts that the fundamental physiological hypotheses of the polyvagal theory are untenable and must be considered largely refuted. Furthermore, the major psychological constituents of polyvagal theory – attachment, co-regulation, social engagement, and intero ceptive processes beyond conscious awareness – each predate polyvagal speculations by decades; there is also a depth of thought and literature readily available that does not require physiological justifications for their uses in psychology or psychotherapy. For those desiring a more biological understanding of these processes, there are other models of explanation, integrating the entire nervous system, that correspond with current understanding of body and mind.

Abstract

The quaternary structure of Eudistylia vancouverii chlorocruorin and its subunits was investigated using maximum entropy deconvolution of the electrospray ionization mass spectrometry. Live Eudistylia vancouverii were used in the study. Results showed that the hierarchy of disulfide-bonded globin subunits of Eudistylia chlorocruorin has a built-in heterogeneity of hexagonal bilayer quaternary structures.

Abstract

A study conducted on the conformation of the free thiols present in platelet thrombospondin (TSP) using electron spin resonance and fluorescence studies shows that the TSP thiols have three conformations which are in dynamic equilibrium. This equilibrium and the reaction of TSP with other macromolecules is controlled by calcium. The formation of the noncovalent complex by the interaction of TSP with thrombin does not require thrombin activity, but the formation of a covalent complex does.

Abstract

A study was done to examine the establishment of conditions governing working capital. Earlier research considered the ommission or the inclusion of ad hoc figures for valuating working cash flows. It is shown that an endogenous system for measuring working capital cash flows may be developed on a periodic basis. In addition, the exclusion of endogeneity may generate a biased present value for cash flows., Introduction In a recent article in this journal Stevens |5~ presents a convincing case for the inclusion of working capital requirements in capital budgeting analysis. Rigorous proofs demonstrate the importance [...]

43. Calculating the temperature and degree of cross‐linking for liquid silicone rubber processing in injection molding.

Abstract

Processing of liquid silicone rubber (LSR) in the injection molding process has a high economic potential. Since there are some fundamental differences compared to classical thermoplastic injection molding, up to now there is a lack of well‐founded knowledge of the process which allows an estimation of the cycle time. Because, in addition to reverse temperature control, LSR processing also involves an irreversible temperature‐ and time‐dependent chemical reaction. In this paper, the complex cross‐linking reaction is first modelled phenomenologically using dynamic differential scanning calorimetry (DSC) measurements and the well‐fitting Kamal‐Sourour model. Afterwards, a temperature and cross‐linking simulation is set up, which reliably simulates the time‐ and travel‐dependent temperature profile and degree of cross‐linking in the mold. Therefore, the released exothermic cross‐linking heat is also taken into account. The simulated temperature values are verified with measurements in the cavity during the injection molding process. The measured values correspond very well with the simulated values at different mold temperatures. It is shown that the influence of the cross‐linking heat on the overall temperature profile in the LSR component during the injection molding process is relatively low. Nevertheless, the model is necessary to determine the degree of cross‐linking ‐ it can be used to calculate the cycle time at which the component of a certain cross‐section can be ejected at a known tool temperature and is fully cross‐linked. With this knowledge, existing processes can be optimized in terms of mold temperature and curing time, but also new components can be calculated economically. [ABSTRACT FROM AUTHOR]
