3.4 Arousal

We can identify three types of arousal during the hibernation period, on temporal rather than physiological grounds. The first is alarm arousal, in response to a major exogenous stimulus such as a sudden large drop in environmental temperature. The second is a periodic arousal when, in the absence of external cues, the animal spontaneously begins to re-warm. The third is the final arousal in the spring when the animal does not re-enter hibernation but emerges to a sustained euthermia. Physiol

Introduction

This unit explores different understandings of nature and environment and the significance these may have for developing responsibility. The problems of connecting human and non-human nature are presented here as being a challenge peculiar to the concerns of environmental responsibility. They provide the impetus for exploring the idea of ‘conversation’ as a metaphor for what matters in environmental responsibility. Using a reading by Stephen Talbott as a foundation, the conversation me

8.4.2 Closed-loop control

Very often in the manufacture of microsystems, the etching steps are meant to remove a layer of material entirely from within the areas defined by the mask pattern. This offers the opportunity to detect the moment the etch is complete by spotting a change in composition of the reaction products from the etching. This is particularly useful in dry etching, where very small numbers of molecules can be detected using optical or mass-spectrometry-based residual gas analysis. Gaseous reaction prod

12.1.1 Survey questionnaires

Questionnaires are lists of questions that enable information to be gathered efficiently from a relatively large number of respondents. Most questionnaires require a fixed type of response, such as a choice between available answers, or along a scale of response. For example, a product design questionnaire might suggest, ‘I found the product easy to use’ and provide a five-point scale of response from ‘agree strongly’ to ‘disagree strongly’. Or a question might be, ‘how often do

1.2 1.2 What does this unit cover?

This unit offers some responses to these questions by outlining the variety of regions and regionalisms, their growth and its causes, their development in the EU context, and different future scenarios. Section 2 attempts to define ‘region’ and ‘regionalism’ in the face of their extreme cultural, economic and political diversity. Region

3.5 Establishing Ethernet standards

The first Ethernet network was developed in the early 1970s, long before the days of the World Wide Web and personal computers (PCs). It was designed by researchers at the Xerox Palo Alto Research Centre in California, USA to connect the Centre's 'Alto' computers to an office printer.

Ethernet's journey from its modest roots to become the dominant network technology is a fascinating one. One of the main reasons for its success lies with the decision to publish the standard. Standards th

1.2.3 Working with percentages

Table 1 used percentages, rather than actual numbers, to compare the number of people using the internet for each purpose. Numbers are expressed as if they are 'out of a hundred' when using percentages, which makes it easier to compare different values. You can recognise percentages by the % symbol which you can see at the top of the right-hand column of Table 1.

As you can see from halfway down the table, 50% of the people who had used the internet in the previous 3 months used it for

Stem Cell Connectivity {Duke University Research}
A Duke University team has discovered how stem cells build long, slender structures that may ferry signals from one place to another, connecting the stem cell to the critical information it needs about its neighbors and its environment. In a March 2015 paper, the team has demonstrated that the structures convey myosin molecules which are known to carry signaling molecules. Assistant research professor Joshua Snyder explains the work in this video. Website: http://duke.edu YouTube: http://youtub
