Background:Polypores as components of forest ecosystems are an important group of wood-inhabiting fungi playing a key role in forest regeneration. Previously, studies on polypore funga and diversity were focused on limited areas within one land mass only. What are the polypore funga and species composition for large-scale of China, North America and Europe? The funga and species composition of polypores in the three land masses will supply an important source of reference for the distribution patterns of polypores at species level or higher taxa. In the present study the diversity and species composition of polypores in China, North America and Europe are compared based on published ***:The species diversity, species composition, major genera and nutritional modes of polypores in the three land masses are comparatively ***:A grand total of 1,337 polypore species, belonging to 11 orders, 43 families and 168 genera, have been recorded in these three land masses of the Northern Hemisphere, of which 854 species occur in China, 547 species in North America, and 432 species in Europe. Polyporales, Hymenochaetales and Russulales are the three major orders, and Hymenochaetaceae, Polyporaceae, and Fomitopsidaceae are the three major families. The brown rot fungi Antrodia and Postia have highest number of species at generic level in the three land masses. The proportionally highest number of white rot polypore species is in China (78.81%), followed by North America (73.86%)and then Europe (67.82%);conversely, the proportion of brown rot polypores is highest in Europe (28.47%) then North America (21.39%) and then China (15.57%).Conclusions:China had the highest polypore diversity followed by North America, and then Europe although North America is around twice as big as China and Europe. White rot is the major nutritional mode of all the polypores in China, North America and Europe accounting for 77.04%of all polypore species. The white rot species as a p

Additive Manufacturing (AM) technologies have progressed in the past few years and many of them are now capable of producing functional parts instead of mere prototypes. AM provides a multitude of benefits, especially in design freedom. However, it still lacks industrial relevance because of the absence of comprehensive design rules for AM. Although AM is usually advertised as being the solution for all traditional manufacturing design limitations, the fact is that AM only replaces these limitations with a different set of restrictions. To fully exploit the advantages of AM, it is necessary to understand these limitations and consider them early during the design process. The establishment of design considerations in AM enables parts and process optimization. This paper discusses the design considerations that will lead to optimize part quality. Specifically, the work discusses the Fused Deposition Modeling (FDM) due to its common use and availability. These considerations are drawn from literature and from experiments done by the authors. The experiments done by the authors include an investigation for the influence of elevated service temperature on the performance of FDM PLA parts, benchmarking the capability of FDM to print overhangs and bridges without supports, studying the influence of processing parameters over dimensional accuracy, and the effect of processing parameters on the final FDM samples modulus of elasticity. The work presents a case study investigating the correct clearances for FDM parts and finally a redesign for AM case study of a support bracket originally manufactured using traditional manufacturing methods taking into consideration the design considerations discussed in this paper.

As a member of the Frizzled family, Frizzled3 (FZD3) is a receptor of the canonical Wnt signaling pathway and plays a vital role in mammalian hair follicle developmental processes. However, its effects on wool traits are not clear. The objectives of this study were to identify the single nucleotide polymorphisms (SNPs) and the expression patterns of FZD3 gene, and then to determine whether it affected wool traits of Chinese Merino sheep (Xinjiang Type) or not. PCR-single stranded conformational polymorphism (PCR-SSCP) and sequencing were used to identify mutation loci, and general linear model (GLM) with SAS 9.1 was used for the association analysis between wool traits and SNPs. Quantitative real-time PCR (qRT-PCR) was used to investigate FZD3 gene expression levels. The results showed that six exons of FZD3 gene were amplified and two mutation loci were identified in exon 1 (NC_019459.2: g.101771685 T>C (SNP1)) and exon 3 (NC_019459.2: g.101810848, A>C (SNP2)), respectively. Association analysis showed that SNP1 was significantly associated with mean fiber diameter (MFD)(P=0.04) and live weight (LW)(P=0.0004), SNP2 was significantly associated with greasy fleece weight (GFW)(P=0.04). The expression level of FZD3 gene in skin tissues of the superfine wool (SF) group was significantly lower (P<0.05) than that of the fine wool (F) group. Moreover, it had a higher expression level (P<0.01) in skin tissues than in other tissues of Chinese Merino ewes. While, its expression level had a fluctuant expression in skin tissues at different developmental stages of embryos and born lambs, with the highest expression levels (P<0.01) at the 65th day of embryos. Our study revealed the genetic relationship between FZD3 variants and wool traits and two identified SNPs might serve as potential and valuable genetic markers for sheep breeding and lay a molecular genetic foundation for sheep marker-assisted selection (MAS).
