Double-yolked (DY) and single-yolked (SY) duck eggs (n = 1318 for both) were candled and weighed on Days (d) 2, 8, 12, 15, 19, 22 and 25 of incubation and yolk/embryo position was recorded on d2, d8 and at post-mortem. From d8 only eggs with live fertile yolk(s) remained in the incubator. On d2, 99.39% of yolks in DY eggs were in the adjacent position and by d8 yolk positions changed to paralle...

In the context of holographic QCD we analyze Sakai-Sugimoto’s chiral model at finite baryon density and zero temperature. The baryon number density is introduced through compact D4 wrapping S4 at the tip of D8-D8. Each baryon acts as a chiral point-like source distributed uniformly over R3, and leads a non-vanishing U(1)V potential on the brane. For fixed baryon charge density nB we analyze the...

Environmental sustainability is an important issue for many individuals, businesses, and governments nowadays. One of the road blocks to sustainable practice is cost, which is an important consideration, particularly for business. The eco-efficiency movement was initiated to address this concern. This chapter reviews the eco-efficiency concept and explains why it is becoming a current issue for...

We present a holographic dual of four-dimensional, large Nc QCD with massless flavors. This model is constructed by placing Nf probe D8-branes into a D4 background, where supersymmetry is completely broken. The chiral symmetry breaking in QCD is manifested as a smooth interpolation of D8-D8 pairs in the supergravity background. The meson spectrum is examined by analyzing a five-dimensional Yang...

The major goal of ecological evolutionary developmental biology, also known as "eco-evo-devo," is to uncover the rules that underlie the interactions between an organism's environment, genes, and development and to incorporate these rules into evolutionary theory. In this chapter, we discuss some key and emerging concepts within eco-evo-devo. These concepts show that the environment is a source...

INTRODUCTION On 8 June 2017, the Supreme Court in the United Kingdom rejected a legal appeal in the high-profile case of Charlie Gard, a British infant with a severe genetic disorder whose parents had disagreed with medical professionals and were requesting treatment that the doctors believed was futile. The case was the latest in a series of UK legal cases where courts have authorized withdraw...

SimC7 is a polyketide ketoreductase involved in biosynthesis of the angucyclinone moiety of the gyrase inhibitor simocyclinone D8 (SD8). SimC7, which belongs to the short-chain dehydrogenase/reductase (SDR) superfamily, catalyzes reduction of the C-7 carbonyl of the angucyclinone, and the resulting hydroxyl is essential for antibiotic activity. SimC7 shares little sequence similarity with chara...

Innovativeness, determining the development potential of enterprises and economies, and hence the economic welfare of societies, became an important area of interest for both theoreticians and especially economic life practitioners. Thus, in this study of the subject there can be found numerous definitions and types of innovation, including environmental innovation, being a response to the dema...
