A Multicenter, Prospective, Randomized, Contralateral Study of Tissue Liquefaction Liposuction vs Suction-Assisted Liposuction

Tissue liquefaction liposuction (TLL) deploys a novel energy source utilizing a stream of warmed, low-pressurized, and pulsed saline to extract fat tissue. Objectives: Compare TLL to suction-assisted liposuction (SAL) to determine which device is more efficient for surgeons and provides better recovery for patients. Methods: Thirty-one adult female patients were followed prospectively in a contralateral study design comparing differences in bruising, swelling, tenderness, and incision appearance ratings between TLL and SAL procedures. Surgical efficiency and appearance of the lipoaspirate were also compared. Results: All 31 patients successfully completed the study. For TLL and SAL procedures, the average volumes of infusion (1.242 vs 1.276 L) and aspirated supernatant fat (704 vs 649 mL) were statistically similar. TLL median fat extraction rate was faster than SAL (35.6 vs 25 mL/min; P < 0.0001), and stroke rate was reduced in TLL vs SAL procedures (48 vs 120 strokes/min; P < 0.0001), and both were statistically significant. The mean total scores for bruising, swelling, treatment site tenderness, and incision appearance were lower, indicating improved patient recovery on the TLL side. Conclusions: TLL and SAL techniques produced comparable volume of fat aspirate. TLL demonstrated a 42% faster fat extraction rate and a 68% reduction in arm movements needed to complete the procedure compared to SAL, both of these differences are statistically significant. The TLL side was noted to have reduced bruising and swelling and improved incision site appearance with less tenderness compared to the SAL side

People, place and fish: Exploring the Cultural Ecosystem Services of Inshore Fishing through Photography

The Millennium Ecosystem Assessment (MEA, 2005) set out a framework for understanding the benefits that humans derive from the environment in order to inform decision making. It categorized these benefits as: provisioning services, such as food, water, timber; regulating services, such as climate control, waste, water quality; supporting services, such as soil formation, photosynthesis, nutrient cycling; and cultural services, such as recreational, spiritual and aesthetic benefits. Since then there has been a plethora of research and wider interest in devising ways of assessing and measuring those services (Haines-Young and Potschin, 2009; Sagoff, 2011; Shan and Swinton, 2011), often involving economic valuation techniques devised by economists and ecologists. While these can be useful for assessing the provisioning, supporting and regulating services, measuring or assessing the cultural services that humans receive from ecosystems has proved to be more problematic. However, there is increasing recognition of the role of multiple disciplines in understanding the complex and multi-faceted ways that ecosystems shape culture and cultural value

Nature tables: Discovering Children's interest in natural objects

Primary school pupils in the UK today may be less familiar with natural objects, less exposed to formal natural history teaching and have less time given to school-based observation and discussion of natural objects. This study of children’s responses to a ‘Nature Table’ of displayed natural objects was designed to assess pupils’ knowledge of those objects, the sources of their knowledge and the phenomenological nature of those children’s interest in items which they selected to talk about or to photograph. Children in the study were drawn from the first year of formal schooling (age 5-6) and the fifth year of formal schooling (age 9-10). Responses have been recorded and analysed using a simple systemic network. Results show that pupils are attracted most towards items with: an animate or novel nature or appearance, or for which they have some prior familiarity. Items are also attractive if they have aesthetic attributes, which display some responsiveness to the child or engage with the child’s previous experience, or elicit affective feeling. The present study reveals a greater home-based, rather than school-based, source for much of this experience and suggests how the criteria for teachers selecting natural objects for learning in school might be improved

Absorbing new subjects: holography as an analog of photography

I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900–1979) in England,Yury N. Denisyuk (b. 1924) in the Soviet Union, and Emmett N. Leith (1927–2005) and Juris Upatnieks (b. 1936) in the United States. I show that the evolution of holography was simultaneously promoted and constrained by its identification as an analog of photography, an association that influenced its assessment by successive audiences of practitioners, entrepreneurs, and consumers. One consequence is that holography can be seen as an example of a modern technical subject that has been shaped by cultural influences more powerfully than generally appreciated. Conversely, the understanding of this new science and technology in terms of an older one helps to explain why the cultural effects of holography have been more muted than anticipated by forecasters between the 1960s and 1990s

LANDSCAPE AND LAND PROPERTY RIGHT

This article shows how individuals privatise the landscape. It reminds us that landscape was invented by art, and painting in particular. (1). An elite modified the outlook on nature. It made landscape of the countryside. Once individuals give aesthetic value to land, they buy not only the property rights to plant seed or build, but also to look. The demand for landscape thus leads to a supply of development in order to look at it. This means producing viewing points (2) controlling their extension (3) and protecting image rights on property.land, property right, public good and property right
