Mathematical Patterns in Chemistry – on Turn Points in the Molecular Self-Assemblage Symmetry Formation

Does the abstract mathematics afford patterns for chemistry? It is supposed that mathematics has its own, autonomous criteria of development and that mathematical creativity cannot be progressed simply by a "blind" listing of possible tautologies. Simultaneously, applied findings in the independently developed mathematical areas are rather a rare case. In the present work, it has been shown that seemingly abstract and presumed not to have any direct application concepts of pure mathematics lead to the concrete entities encountered in chemistry. For these reasons, the general definition of molecular forms and mathematical atoms have been employed to derive objects corresponding to the basic particles of chemistry. Besides, using a pattern of foundations of arithmetic, a special relation has been found to determine such atomic species in some chemical categories. The arithmetical background of chemistry and possible extensions have been indicated in this way. </p

DECODING MOLECULAR PROCESSOR INFORMATION

There are non-imaginable resources of information inherently stored and naturally processed in the physical world. Eliciting and processing information does assume, as usual, the existence of the system (e. g., classic logical gates) suitable for operations or measurements performed. Meanwhile, the powerful chemical and other complex system conversions of information have not used implementation of this kind. Processes in living and non-living physical world run with immediate changes of the properties of objects constituting complex systems. We can detect the features of changing structures and thus to acquire the knowledge about environment. The main part of the structural properties and processes is however hidden though it can underlie important transformations. A massive information which is cumulated and processed in structures of complex systems turns out to constitute a kind of a specific number processor. Thus, the information by which the molecular systems are loaded is to be elicited and transformed to the forms suitable for detection.Pozna

Students as producers and active partners in enhancing equality and diversity: ‘culturosity’ at Canterbury Christ Church University

Equality and diversity of truths, of opportunity, of outcome, of dignity and of identities lie at the heart of the idea of university (Wolff, 1992, p. 68). However, despite the fact that the UK ‘has well-established equality law and practice’ and the Equality Act 2010 requires universities to implement changes that protect their students and employees from various forms and effects of discrimination, ‘inequality remains, albeit often in more complex and subtle forms than have been understood before’, argues David Ruebain (2012, p. 3). This study contributes to the discussion about equality and diversity practices in the university context by proposing strategies to embed into students’ learning community equality and diversity and subsequent graduate attributes. The case study is the Culturosity Project: an equality and diversity training initiative co-created by Dr Kasia Lech and a group of final-year students and graduates from Drama and Performing Arts programmes and delivered – as a Canterbury Christ Church University Partners in Learning project – to L4 and foundation-year students. The project was first delivered in 2015 and has now become part of student induction at the CCCU Faculty of Arts and Humanities

Chiral Symmetry Breaking in Bent-Core Liquid Crystals

By molecular modeling we demonstrate that the nematic long-range order discovered in bent-core liquid crystal systems should reveal further spatially homogeneous phases. Two of them are identified as a tetrahedratic nematic ($N_T$) phase with $D_{2d}$ symmetry and a chiral tetrahedratic nematic ($N_T^*$) phase with $D_2$ symmetry. These new phases were found for a lattice model with quadrupolar and octupolar anisotropic interactions using Mean Field theory and Monte Carlo simulations. The phase diagrams exhibit tetrahedratic ($T$), $N_T$ and $N_T^*$ phases, in addition to ordinary isotropic ($I$), uniaxial nematic ($N_U$) and biaxial nematic ($N_B$) phases. To our knowledge, this is the first molecular model with spontaneous chiral symmetry breaking in non-layered systems.Comment: 12 pages, 4 figures, submitted for publicatio

Space station common module network topology and hardware development

Conceptual space station common module power management and distribution (SSM/PMAD) network layouts and detailed network evaluations were developed. Individual pieces of hardware to be developed for the SSM/PMAD test bed were identified. A technology assessment was developed to identify pieces of equipment requiring development effort. Equipment lists were developed from the previously selected network schematics. Additionally, functional requirements for the network equipment as well as other requirements which affected the suitability of specific items for use on the Space Station Program were identified. Assembly requirements were derived based on the SSM/PMAD developed requirements and on the selected SSM/PMAD network concepts. Basic requirements and simplified design block diagrams are included. DC remote power controllers were successfully integrated into the DC Marshall Space Flight Center breadboard. Two DC remote power controller (RPC) boards experienced mechanical failure of UES 706 stud-mounted diodes during mechanical installation of the boards into the system. These broken diodes caused input to output shorting of the RPC's. The UES 706 diodes were replaced on these RPC's which eliminated the problem. The DC RPC's as existing in the present breadboard configuration do not provide ground fault protection because the RPC was designed to only switch the hot side current. If ground fault protection were to be implemented, it would be necessary to design the system so the RPC switched both the hot and the return sides of power

Expression pattern of STAT5A gene during early bovine embryogenesis

Growth hormone (GH) plays an important role in early embryo development. It has been shown to activate multiple pathways, the most comprehensively studied being the STAT/JAK (Signal transducers and activators of transcription/Janus kinase) pathway. The objective of the present study was to investigate STAT5A gene expression during early bovine embryogenesis. Real-time polymerase chain reaction (RT-PCR) was used to measure the abundance of STAT5A transcripts. The mRNA was present at all stages of preimplantation bovine embryos investigated. The most abundant STAT5A expression occurred at the 2-cell stage. Expression was markedly reduced between the 4-cell and 8-cell stages, coinciding with the known time of embryo genome activation and loss of maternal mRNAs. This finding suggests that the embryonic STAT5A gene is primarily activated by maternal gene products

Landau-deGennes Theory of Biaxial Nematics Re-examined

Recent experiments report that the long looked for thermotropic biaxial nematic phase has been finally detected in some thermotropic liquid crystalline systems. Inspired by these experimental observations we concentrate on some elementary theoretical issues concerned with the classical sixth-order Landau-deGennes free energy expansion in terms of the symmetric and traceless tensor order parameter $Q_{\alpha\beta}$. In particular, we fully explore the stability of the biaxial nematic phase giving analytical solutions for all distinct classes of the phase diagrams that theory allows. This includes diagrams with triple- and (tri-)critical points and with multiple (reentrant) biaxial- and uniaxial phase transitions. A brief comparison with predictions of existing molecular theories is also given.Comment: 12 pages, 14 figure
