The shapes of trees are complex and fractal-like, and they have a set of physical, mechanical and biological functions. The relation between them always draws attention of human beings throughout history and, focusing on the relation between shape and structural strength, architects have designed a number of treelike structures, referred as dendriforms. The replication and adoption of the treelike patterns for constructing architectural structures have been varied in different time periods based on the existing and advanced knowledge and available technologies. This paper, by briefly discussing the biological functions and the mechanical properties of trees with regard to their shapes, overviews and investigates the chronological evolution and advancements of dendriform and arboreal structures in architec- ture referring to some important historical as well as contemporary examples.

In this paper, the problem of computing zeros of a general degree bivariate Bernstein polynomial is considered. An efficient and robust algorithm is presented that takes into full account particular properties of the function considered. The algorithm works for rectangular as well as triangular domains. The outlined procedure can also be applied for the computation of the intersection of a Bezier patch and a plane as well as in the determination of an algebraic curve restricted to a compact domain. In particular, singular points of the algebraic curve are reliably detected.

Although the concept of family functioning has gained recent popularity, the terms ＂family functioning＂ and ＂family resilience＂ are sometimes confused and used interchangeably. The aim of this concept analysis was to clarify what is meant by family functioning in the context of diabetes self-management by assessing specific attributes, antecedents, and consequences. A concept analysis model by Walker and Avant was applied. The identified attributes of family functioning in a diabetes self-management context included problem-solving, communication, roles, affective responsiveness, affective involvement, and behavioral control. Antecedents included family structure, socioeconomic status, family functioning relationships, family stage, and life events. Consequences included family satisfaction, family cohesion, and family relationships. This analysis provided a deeper understanding of a family functioning concept within a diabetes self-management context. It is recommended that health care providers should be aware of antecedent factors that could inhibit outcome improvement. Further research is needed to explain family functioning attributes in relation to antecedents and potential consequences.

The synthesis of the title molecule was achieved by the reaction of 2,4-dichloro- benzoyl chloride with potassium thiocyanate in 1：1 molar ratio in dry acetonitrile to afford the corresponding isothiocyante in situ followed by the treatment with 2-aminobiphenyl. The structure of the target compound was established by elemental analysis, FTIR, 1H, 13C NMR and mass spectroscopy and unequivocally confirmed by the crystallographic data. The title compound crystallizes in the monoclinic space group P21/n with a = 13.356（2）, b = 7.0761（11）, c = 20.539（3） A, β = 105.723（4）°, V= 1868.5（5） A3 and Z = 4.

For about three decades, DNA-based nanotechnology has been undergoing development as an assembly method for nanostructured materials. The DNA origami method pioneered by Rothemund paved the way for the formation of 3D structures using DNA self assembly. The origami approach uses a long scaffold strand as the input for the self assembly of a few hundred staple strands into desired shapes. Herein, we present a 3D origami "roller" (75 nm in length) designed using caDNAno software. This has the potential to be used as a template to assemble nanoparticles into different pre-defined shapes. The "roller" was characterized with agarose gel electrophoresis, atomic force microscopy (AFM) and transmission electron microscopy (TEM).
