Chapter 5 describes the stages of digital nomadism through the lens of three vignettes. The first, focused on honeymooners testing out the location-independent lifestyle, features Pauline, a twenty-eight-year-old who arrived in Bali two months after quitting a high-pressure Manhattan job in the music industry. The second vignette illustrates visa runners, who “run” to another country to receive an entry stamp before returning in order to extend their stay past the sixty days allowed on a typical visit visa. It profiles Lucy, a media content creator, who left her job in London to work as a freelancer based in Bali. The final vignette illuminates the lives of resident nomads who have been in Bali for over a year and have no immediate plans to leave. This vignette tells the story of Lorelei and Norman, a couple who moved to Bali in 2014 and have reinvented their lives through online entrepreneurship.

Tehrangeles Dreaming is the first book about the Tehrangeles music industry, that is, the Iranian diaspora music industry brought to life by the expatriate Iranian artists and music producers who settled in Los Angeles and Southern California after the 1979 Iranian revolution. Farzaneh Hemmasi uses an ethnographic approach in combination with an analysis of diaspora media discourse in order to “examine expatriate imaginations of influence on, and intimacy with, their global Iranian audiences” (26). At its core, the book deals with the imagining and reimagining of Iranian identity by the artistic community that creates music and media content for Iranians in Iran and across the world.

Freedom of speech, or freedom of expression of opinion, is one of the oldest human rights guaranteed by the highest legal acts of states as well as international documents. By developing technology, the ability to receive, give, and dissemination information in the form of words, images, or sounds, gains unheard proportions and the rate of information flow is continuously increasing. The question is how citizens, as users of these services, have the ability to freely form and express their opinions in a sea of information that comes from different sources, verified and unverified. The emergence of social media has led to the consumption of media content becoming public. The quantity of these content is evident, but not their quality. What at first glance looks like freedom, due to its wide range of possibilities for broadcasting and information placement, is turning into its own opposite in an era of incomplete, inaccurate or unverified information. The notion of "information pollution" that has emerged in theory since 2003 has been used as a way to reduce pollution. to describe insignificant, leaked and worthless information, it now manifests itself as an information disorder, whose consequences are visible in the most important spheres of the functioning of society, such as elections, and therefore the formation of all other political institutions. Hence, the introduction of a value dimension into the information system, through defining the notion of the credibility of media content and maintaining the standards of its recognition, can be understood as a condition of all conditions for preserving modern democratic institutions. In this sense, media literacy should be introduced as a compulsory part of formal education, with the aim of encouraging critical thinking and continuous rethinking of imposed values. The ability to recognize the authenticity of information becomes a demand of the modern age. Media service providers have a responsibility to preserve the value system of modern society, which is collapsing with a flood of fake news.

The ultrastructure of cells suspended in physiological fluids or cell culture media can only be studied if the living processes are stopped while the cells remain in suspension. Attachment of living cells to carrier surfaces to facilitate further processing for electron microscopy produces a rapid reorganization of cell structure eradicating most traces of the structures present when the cells were in suspension. The structure of cells in suspension can be immobilized by either chemical fixation or, much faster, by rapid freezing (cryo-immobilization). The fixation speed is particularly important in studies of cell surface reorganization over time. High pressure freezing provides conditions where specimens up to 500μm thick can be frozen in milliseconds without ice crystal damage. This volume is sufficient for cells to remain in suspension until frozen. However, special procedures are needed to assure that the unattached cells are not lost during subsequent processing for LVSEM or HVEM using freeze-substitution or freeze drying. We recently developed such a procedure.

Observation of subtle or early signs of change in spaceflight induced alterations on living systems require precise methods of sampling. In-flight analysis would be preferable but constraints of time, equipment, personnel and cost dictate the necessity for prolonged storage before retrieval. Because of this, various tissues have been stored in fixatives and combinations of fixatives and observed at various time intervals. High pressure and the effect of buffer alone have also been tried.Of the various tissues embedded, muscle, cartilage and liver, liver has been the most extensively studied because it contains large numbers of organelles common to all tissues (Fig. 1).

Obtaining frozen-hydrated sections of plant tissues for electron microscopy and microanalysis has been considered difficult, if not impossible, due primarily to the considerable depth of effective freezing in the tissues which would be required. The greatest depth of vitreous freezing is generally considered to be only 15-20 μm in animal specimens. Plant cells are often much larger in diameter and, if several cells are required to be intact, ice crystal damage can be expected to be so severe as to prevent successful cryoultramicrotomy. The very nature of cell walls, intercellular air spaces, irregular topography, and large vacuoles often make it impractical to use immersion, metal-mirror, or jet freezing techniques for botanical material.However, it has been proposed that high-pressure freezing (HPF) may offer an alternative to the more conventional freezing techniques, inasmuch as non-cryoprotected specimens may be frozen in a vitreous, or near-vitreous state, to a radial depth of at least 0.5 mm.

The aim of ultrastructural investigation is to analyze cell architecture and relate a functional role(s) to cell components. It is known that aqueous chemical fixation requires seconds to minutes to penetrate and stabilize cell structure which may result in structural artifacts. The use of ultralow temperatures to fix and prepare specimens, however, leads to a much improved preservation of the cell’s living state. A critical limitation of conventional cryofixation methods (i.e., propane-jet freezing, cold-metal slamming, plunge-freezing) is that only a 10 to 40 μm thick surface layer of cells can be frozen without distorting ice crystal formation. This problem can be allayed by freezing samples under about 2100 bar of hydrostatic pressure which suppresses the formation of ice nuclei and their rate of growth. Thus, 0.6 mm thick samples with a total volume of 1 mm3 can be frozen without ice crystal damage. The purpose of this study is to describe the cellular details and identify potential artifacts in root tissue of barley (Hordeum vulgari L.) and leaf tissue of brome grass (Bromus mollis L.) fixed and prepared by high-pressure freezing (HPF) and freeze substitution (FS) techniques.

High Pressure Sintering

Because of the extremely rigid lattice structure of diamond, generating new dislocations or moving existing dislocations in diamond by applying mechanical stress at ambient temperature is very difficult. Analysis of portions of diamonds deformed under bending stress at elevated temperature has shown that diamond deforms plastically under suitable conditions and that its primary slip systems are on the ﹛111﹜ planes. Plastic deformation in diamond is more commonly observed during the high temperature - high pressure sintering process used to make diamond compacts. The pressure and temperature conditions in the sintering presses are sufficiently high that many diamond grains in the sintered compact show deformed microtructures.In this report commercially available polycrystalline diamond discs for rock cutting applications were analyzed to study the deformation substructures in the diamond grains using transmission electron microscopy. An individual diamond particle can be plastically deformed in a high pressure apparatus at high temperature, but it is nearly impossible to prepare such a particle for TEM observation, since any medium in which the diamond is mounted wears away faster than the diamond during ion milling and the diamond is lost.

High-pressure oxidation of silicon (HIPOX) is one of various techniques used for electrical-isolation of semiconductor-devices on silicon substrates. Other techniques have included local-oxidation of silicon (LOCOS), poly-buffered LOCOS, deep-trench isolation and separation of silicon by implanted oxygen (SIMOX). Reliable use of HIPOX for device-isolation requires an understanding of the behavior of the materials and structures being used and their interactions under different processing conditions. The effect of HIPOX-related stresses in the structures is of interest because structuraldefects, if formed, could electrically degrade devices.This investigation was performed to study the origin and behavior of defects in recessed HIPOX (RHIPOX) structures. The structures were exposed to a boron implant. Samples consisted of (i) RHlPOX'ed strip exposed to a boron implant, (ii) recessed strip prior to HIPOX, but exposed to a boron implant, (iii) test-pad prior to HIPOX, (iv) HIPOX'ed region away from R-HIPOX edge. Cross-section TEM specimens were prepared in the <110> substrate-geometry.

The use of cryo-techniques for the preparation of biological specimens in electron microscopy has led to superior preservation of ultrastructural detail. Although these techniques have obvious advantages, a critical limitation is that only 10-40 μm thick cells and tissue layers can be frozen without the formation of distorting ice crystals. However, thicker samples (600 μm) may be frozen well by rapid freezing under high-pressure (2,100 bar). To date, most work using cryo-techniques on fungi have been confined to examining small, thin-walled structures. High-pressure freezing and freeze substitution are used here to analysis pre-germination stages of specialized, sexual spores (teliospores) of the plant pathogenic fungus Gymnosporangium clavipes C & P.Dormant teliospores were incubated in drops of water at room temperature (25°C) to break dormancy and stimulate germination. Spores were collected at approximately 30 min intervals after hydration so that early cytological changes associated with spore germination could be monitored. Prior to high-pressure freezing, the samples were incubated for 5-10 min in a 20% dextran solution for added cryoprotection during freezing. Forty to 50 spores were placed in specimen cups and holders and immediately frozen at high pressure using the Balzers HPM 010 apparatus.
