Macroalgae and microalgae, including cyanobacteria, are primarily photosynthetic organisms grown for the production of renewable biomass for foods, feedstocks, and high-value specialty chemicals. While there are differences in cultivating and harvesting macro- and microalgae due to scale, many of the same downstream techniques can be used for processing algal biomass. This chapter will outline various developments in processing technologies used for the treatment of algal biomass with discussion of scalability, cost, time, and efficacy. Topics will cover methods for harvesting and dewatering algae, drying algal biomass, biomass disruption, and nutrient recovery, including case studies with lessons learned. The final section presents biomass applications and product considerations. While there is no universally-adopted approach for processing algal biomass, these studies provide the foundation for making informed decisions, considering the unique properties of the algae and the integrity of the desired end products.

This Introduction to the book does three things. First, it introduces the concept of trust and develops a definition of trust as the ‘expectation of no harm in contexts where betrayal is always a possibility’. Next, it identities two conceptions of trust that guide the book, ‘calculative trust’ and ‘trust as suspension’, which provide very different explanations for how actors form expectations that another will be trustworthy. It then shows how trust as suspension opens up a new theory of accurate signal interpretation and demonstrates how this theory is superior to costly signalling-based theories of accurate signal interpretation. The final section of the Introduction sets out the rationale for the case studies and the key assumptions.

Background. Wearable physical activity (PA) trackers are becoming increasingly popular for intervention and assessment in health promotion research and practice. The purpose of this article is to present lessons learned from four studies that used commercial PA tracking devices for PA intervention or assessment, present issues encountered with their use, and provide guidelines for determining which tools to use. Method. Four case studies are presented that used PA tracking devices (iBitz, Zamzee, FitBit Flex and Zip, Omron Digital Pedometer, Sensewear Armband, and MisFit Flash) in the field—two used the tools for intervention and two used the tools as assessment methods. Results. The four studies presented had varying levels of success with using PA devices and experienced several issues that impacted their studies, such as companies that went out of business, missing data, and lost devices. Percentage ranges for devices that were lost were 0% to 29% and was 0% to 87% for those devices that malfunctioned or lost data. Conclusions. There is a need for low-cost, easy-to-use, accurate PA tracking devices to use as both intervention and assessment tools in health promotion research related to PA.

In this paper it is proposed that similarly with the evolution and maturation of any organization, the Linking and Management of Technology Office (L & MoT) of a public R&D Mexican Centre has been evolved and is in the way to be transformed into a Technology Transfer Office (TTO). Case of fifteen year evolution of the Centro de Ciencias Aplicadas y Desarrollo Tecnológico L & MoT presents empirical evidence to identify the main phases and actions that have been driving this process along this time. Standard results obtained through the years using the L & MoT Management of Technology Model (MoT) are presented. Emphasis is placed in a final section with the lessons obtained from non-standard results coming from unsuccessful negotiations and failed link actions between the Center and some external organizations. Experience has shown that not all negotiations are successful but curiously, the best lessons for the personnel of a technology transfer office are probably derived from these problematic cases.

Abstract The present paper suggests that the recurring appeal to kinship diplomacy undermines a fixed idea of ‘nation’ in Archaic Greece, especially in the first two decades of the fifth century BC. It aims to present a series of test cases in Herodotus that explain why contemporary patterns and theories on ancient ethnicity can hardly explain the totality of the historical spectrum. Blood ties could sometimes fortify ethnic relationships, as in the case of Aristagoras’ mission to Sparta (Hdt. 5.49.3), since the common Greekness could elicit the Spartan to help to the Ionians. In other times, the same blood ties were applied to divine genealogies, and they could also be used to show the feeble devotion of cities like Argos to the Greek cause (7.150.2: Xerxes expects the Argives to join the Persian cause, since they descend from Perses). Habits and traditions, often taken as indicia of national feeling, could be thought of as clues of ancient migrations (so the Trojans became Maxyes in Lybia: 4.191). Even language might not help in justifying ethnic relationships: for instance, the Greeks living in the Scythian Gelonus spoke a mixed language (4.108). These few case studies may shed a different light on the classical definition of Greekness (to hellenikon) in terms of blood, language, cults, and habits, all given by Herodotus (8.144). Far from being a valid label for all the Greeks of the fifth century, this statement owes much to a specific variety of the language of kinship diplomacy. The final section argues for the opportunity to avoid the later and misleading idea of nation when studying Herodotus and the age of the Persian Wars, which are instead characterized by various and contrasting strategies. Greek groups and ethne can be better described as networks of lightly defined communities.

It’s always challenging and exciting to find topics for the readers’ advisory column, and professionals willing to write for them! I’ve been so thankful to the many professionals who have so generously given their time and shared their expertise for this column. From lessons learned, case studies and differing opinions on RA and its future, it is amazing how various and rich this area of librarianship is—and how rewarding and frustrating! In an effort to continue to provide a broad spectrum of thoughts and ideas, I asked Dr. Louise Spiteri of Dalhousie University to write for this issue. Spiteri recently completed two stages of research examining subject headings and user-generated content and how these connect with RA access points. Jen Pecoskie was Spiteri’s research partner in both studies.—Editor

This report presents lessons learned from twenty-five worldwide real-life case studies implementing the integration of daylighting and electric lighting. The case studies were monitored with respect to energy use for lighting, visual performance, non-visual performance, and users’ satisfaction. The monitoring is largely based on field measurements, but it is also complemented with simulations and calculations where needed.
