Pulmonary Surfactant: the Key to the Evolution of Air Breathing Christopher B
Pulmonary Surfactant: The Key to the Evolution of Air Breathing Christopher B. Daniels and Sandra Orgeig Department of Environmental Biology, University of Adelaide, Adelaide, South Australia 5005, Australia Pulmonary surfactant controls the surface tension at the air-liquid interface within the lung. This sys- tem had a single evolutionary origin that predates the evolution of the vertebrates and lungs. The lipid composition of surfactant has been subjected to evolutionary selection pressures, partic- ularly temperature, throughout the evolution of the vertebrates. ungs have evolved independently on several occasions pendent units, do not necessarily stretch upon inflation but Lover the past 300 million years in association with the radi- unpleat or unfold in a complex manner. Moreover, the many ation and diversification of the vertebrates, such that all major fluid-filled corners and crevices in the alveoli open and close vertebrate groups have members with lungs. However, lungs as the lung inflates and deflates. differ considerably in structure, embryological origin, and Surfactant in nonmammals exhibits an antiadhesive func- function between vertebrate groups.

Henry's Law Constants and Micellar Partitioning of Volatile Organic
38 J. Chem. Eng. Data 2000, 45, 38-47 Henry’s Law Constants and Micellar Partitioning of Volatile Organic Compounds in Surfactant Solutions Leland M. Vane* and Eugene L. Giroux United States Environmental Protection Agency, National Risk Management Research Laboratory, 26 West Martin Luther King Drive, Cincinnati, Ohio 45268 Partitioning of volatile organic compounds (VOCs) into surfactant micelles affects the apparent vapor- liquid equilibrium of VOCs in surfactant solutions. This partitioning will complicate removal of VOCs from surfactant solutions by standard separation processes. Headspace experiments were performed to quantify the effect of four anionic surfactants and one nonionic surfactant on the Henry’s law constants of 1,1,1-trichloroethane, trichloroethylene, toluene, and tetrachloroethylene at temperatures ranging from 30 to 60 °C. Although the Henry’s law constant increased markedly with temperature for all solutions, the amount of VOC in micelles relative to that in the extramicellar region was comparatively insensitive to temperature. The effect of adding sodium chloride and isopropyl alcohol as cosolutes also was evaluated. Significant partitioning of VOCs into micelles was observed, with the micellar partitioning coefficient (tendency to partition from water into micelle) increasing according to the following series: trichloroethane < trichloroethylene < toluene < tetrachloroethylene. The addition of surfactant was capable of reversing the normal sequence observed in Henry’s law constants for these four VOCs. Introduction have long taken advantage of the high Hc values for these compounds. In the engineering field, the most common Vast quantities of organic solvents have been disposed method of dealing with chlorinated solvents dissolved in of in a manner which impacts human health and the groundwater is “pump & treat”swithdrawal of ground- environment. -
Dive Theory Guide
DIVE THEORY STUDY GUIDE by Rod Abbotson CD69259 © 2010 Dive Aqaba Guidelines for studying: Study each area in order as the theory from one subject is used to build upon the theory in the next subject. When you have completed a subject, take tests and exams in that subject to make sure you understand everything before moving on. If you try to jump around or don’t completely understand something; this can lead to gaps in your knowledge. You need to apply the knowledge in earlier sections to understand the concepts in later sections... If you study this way you will retain all of the information and you will have no problems with any PADI dive theory exams you may take in the future. Before completing the section on decompression theory and the RDP make sure you are thoroughly familiar with the RDP, both Wheel and table versions. Use the appropriate instructions for use guides which come with the product. Contents Section One PHYSICS ………………………………………………page 2 Section Two PHYSIOLOGY………………………………………….page 11 Section Three DECOMPRESSION THEORY & THE RDP….……..page 21 Section Four EQUIPMENT……………………………………………page 27 Section Five SKILLS & ENVIRONMENT…………………………...page 36 PHYSICS SECTION ONE Light: The speed of light changes as it passes through different things such as air, glass and water. This affects the way we see things underwater with a diving mask. As the light passes through the glass of the mask and the air space, the difference in speed causes the light rays to bend; this is called refraction. To the diver wearing a normal diving mask objects appear to be larger and closer than they actually are. -

In Final Form: April 3, 2005 A new method combining axisymmetric drop shape analysis (ADSA) and a captive bubble (CB) is proposed to study the effect of surfactant on interfacial gas transfer. In this method, gas transfer from a static CB to the surrounding quiescent liquid is continuously recorded for a short period (i.e., 5 min). By photographical analysis, ADSA-CB is capable of yielding detailed information pertinent to the surface tension and geometry of the CB, e.g., bubble area, volume, curvature at the apex, and the contact radius and height of the bubble. A steady-state mass transfer model is established to evaluate the mass transfer coefficient on the basis of the output of ADSA-CB. In this way, we are able to develop a working prototype capable of simultaneously measuring dynamic surface tension and interfacial gas transfer. Other advantages of this method are that it allows for the study of very low surface tensions (<5 mJ/m2) and does not require equilibrium of gas transfer. -
Perspectives on Mucus Secretion in Reef Corals
MARINE ECOLOGY PROGRESS SERIES Vol. 296: 291–309, 2005 Published July 12 Mar Ecol Prog Ser REVIEW Perspectives on mucus secretion in reef corals B. E. Brown*, J. C. Bythell School of Biology, Newcastle University, Newcastle upon Tyne NE1 7RU, UK ABSTRACT: The coral surface mucus layer provides a vital interface between the coral epithelium and the seawater environment and mucus acts in defence against a wide range of environmental stresses, in ciliary-mucus feeding and in sediment cleansing, amongst other roles. However, we know surpris- ingly little about the in situ physical and chemical properties of the layer, or its dynamics of formation. We review the nature of coral mucus and its derivation and outline the wide array of roles that are pro- posed for mucus secretion in corals. Finally, we review models of the surface mucus layer formation. We argue that at any one time, different types of mucus secretions may be produced at different sites within the coral colony and that mucus layers secreted by the coral may not be single homogeneous layers but consist of separate layers with different properties. This requires a much more dynamic view of mucus than has been considered before and has important implications, not least for bacterial colonisation. Understanding the formation and dynamics of the surface mucus layer under different environmental conditions is critical to understanding a wide range of associated ecological processes.

What Happens to Herbicides After We Apply Them? by Kyra Clark
Refuge Notebook • Vol. 19, No. 38 • September 22, 2017 What happens to herbicides after we apply them? by Kyra Clark some of the more than 110 exotic plant species in- troduced to the Kenai Peninsula. Over the years, we have been spot treating invasive plants at trail- heads and boat launches, keeping the refuge notice- ably cleaner than the rest of the peninsula. We typ- ically use three chemicals: glyphosate, aminopyralid and fluridone. These are the active ingredients in the different commercial herbicides we use to control or kill target species. The big differences between DDT and other pesti- cides used in Carson’s time and those we use now are their environmental fate and how they degrade over time. DDT has a half-life (time required for half of the original concentration to degrade) of 2–15 years. DDT can also leach into water sources and bio-accumulate in the tissues of animals. In contrast, the three chem- icals we use all have half-lives under a year, do not leach, and do not bio-accumulate in animals. There has been a lot of bad press about glyphosate, but most issues with glyphosate products are asso- ciated with its use in agriculture where herbicides are applied chronically or genetically encoded into seeds. Glyphosate products vary in their formula- tions of glyphosate, the carrier solution, and surfac- tant. Surfactants enhance the active ingredient’s ef- fectiveness by breaking surface tension of the liquid herbicide to improve its coverage of foliage, its ability to stick to foliage, and its rainfastness. We typically use two glyphosate formulations for terrestrial weed control on the refuge.
