Characteristics of cyprinid herpesvirus 3 in different phases of infection: Implications for disease transmission and control
submitted by grenzy 20 minutes ago - Topic: Biology
Koi herpesvirus disease (KHVD) is an emerging and highly contagious viral disease of koi and common carp (Cyprinus carpio), causing mass mortalities and huge economic losses to the carp aquaculture industry. The disease has spread rapidly to 28 countries worldwide. However, mechanisms of koi herpesvirus (species Cyprinid herpesvirus 3; CyHV-3) transmission remain unclear. A potential experiment...



The Phenomenology of Lucid Dreaming: An Online Survey
submitted by pitishorp11 21 minutes ago - Topic: Health
In lucid dreams the dreamer is aware that he or she is dreaming. Although such dreams are not that uncommon, many aspects of lucid dream phenomenology are still unclear. An online survey was conducted to gather data about lucid dream origination, duration, active or passive participation in the dream, planned actions for lucid dreams, and other phenomenological aspects. Among the 684 respondent...

Characterization of space weathering from Lunar Reconnaissance Orbiter Camera ultraviolet observations of the Moon
submitted by rabhawett 22 minutes ago - Topic: Geography
We investigate the effects of space weathering at ultraviolet wavelengths using a near global seven-band (321–689 nm) mosaic from the Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC). We confirm that for moderate- to high-iron compositions (> ~ 5 wt% FeO), the steeply positive UV slope at wavelengths ...

Chandrayaan-1 observations of backscattered solar wind protons from the lunar regolith: Dependence on the solar wind speed
submitted by rabhawett 22 minutes ago - Topic: Geography
We study the backscattering of solar wind protons from the lunar regolith using the Solar Wind Monitor (SWIM) of the Sub-keV Atom Reflecting Analyzer (SARA) on Chandrayaan-Our study focuses on the component of the backscattered particles that leaves the regolith with a positive charge. We find that the fraction of the incident solar wind protons that backscatter as protons, i.e., the proton-bac...

Structural and Tidal Models of Titan and Inferences on Cryovolcanism
submitted by rabhawett 22 minutes ago - Topic: Geography
Titan, Saturn's largest satellite, is subject to solid body tides exerted by Saturn on the time-scale of its orbital period. The tide-induced internal redistribution of mass results in tidal stress variations, which could play a major role for Titan's geologic surface record. We construct models of Titan's interior that are consistent with the satellite's mean density, polar moment-of-inertia f...



Behavior of bromide, chloride and phosphate during low temperature aqueous Fe(II) oxidation processes on Mars
submitted by rabhawett 22 minutes ago - Topic: Geography
Behaviors of bromide, chloride and phosphate were studied experimentally under previously proposed Martian diagenetic conditions, involving jarosite (KFe3(OH)6(SO4)2), goethite (α-FeOOH) and hematite (α-Fe2O3). Experiments evaluated: 1) behavior of Cl-/Br- with and without aqueous phosphate during oxidation of Fe2+ to Fe3+; 2) stability of halogen-bearing jarosite; and 3) uptake of Cl-, Br-, ...

MSL APXS Titanium Observation Tray Measurements: Laboratory Experiments and Results for the Rocknest Fines at the Curiosity Field Site in Gale Crater, Mars
submitted by rabhawett 22 minutes ago - Topic: Geography
The Mars Science Laboratory (MSL) rover, Curiosity, has a titanium science observation tray (o-tray), upon which portions from drilled and scooped martian samples can be delivered for analyses by the alpha-particle X-ray spectrometer (APXS). The standard APXS calibration approach to derive elemental concentrations cannot be applied to samples on the o-tray because they 1) have a non-uniform thr...


Symptoms and signs in interpreting Gamma-hydroxybutyrate (GHB) intoxication - an explorative study
submitted by sahamplontotean 24 minutes ago - Topic: Health
Acute poisoning with gamma-hydroxybutyrate (GHB) has been a serious medical and social problem in different parts of the world including Sweden. GHB is a drug of abuse which acts primarily as central nervous system (CNS) depressants. GHB has serious toxicity, although many young users do not recognise GHB as a dangerous drug. The aim of this pilot study was to explore how symptoms with risk of ...

Prey detection in juveniles of an agamid lizard, Calotes versicolor (Daudin, 1802) (Reptilia: Squamata)
submitted by csastadint 25 minutes ago - Topic: Biology
The relative importance of visual and chemical cues of prey in their detection by the juveniles of Calotes versicolor was studied using laboratory-born, 2-month-old individuals starved for 48 hrs. Grasshoppers served as the prey in all experiments. In trials with deionized water and cologne water (pungency control), the lizards showed no tongue flicking. Presentation of prey-body chemical cues...


Becoming Disabled: The Association between Disability Onset in Younger Adults and Subsequent Changes in Productive Engagement, Social Support, Financial Hardship and Subjective Wellbeing
submitted by rabirtt 27 minutes ago - Topic: Health
Very few population-based studies have investigated the association between the onset of health conditions/impairments associated with disability and subsequent well-being. / To examine the association between the onset of disability and four indicators of well-being (full-time engagement in employment or education, financial hardship, social support, subjective well-being) among a nationally r...

Runoff-mediated seasonal oscillation in the dynamics of dissolved organic matter in different branches of a large bifurcated estuary - the Changjiang Estuary
submitted by shohen76 27 minutes ago - Topic: Geography
The Changjiang Estuary is a large bifurcated estuary where different hydrodynamic processes influence its South Branch compared to its North Branch. The South Branch is the dominant pathway of Changjiang River discharge, while the shallower and narrower North Branch is dominated by salt water intrusion, especially in the dry season. Absorption and fluorescence spectroscopy were measured along w...


Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts—Emerging Risks and Way Out
submitted by maamtoz 27 minutes ago - Topic: Biology
Our article draws attention to a crucial factor frequently omitted from the global development agenda, namely the explosive population growth inevitably expected in Tropical Africa in the nearest decades as a result of the region's laggardness in fertility transition. Population doubling (or even tripling) in the next decades can seriously undermine the development prospects of Tropical African...

Southern France riverbank projects in Montpellier and Perpignan: from designed space to interpreted space
submitted by moxmandimbo 32 minutes ago - Topic: Environment
This examination of recent landscape architecture interventions along two rivers in southern France—the River Lez in Montpellier and the River Têt in Perpignan—questions the popular notion of ‘intervening in space’. Observing the features of the interventions and their consequences, the author investigates whether a change of paradigm occurs with regard to the approach employed. The re...

Homeless Women's Experiences of Service Provider Encounters
submitted by bibi 34 minutes ago - Topic: Health
Service providers are gatekeepers to health-sustaining services and resources, although little is known about service encounters from the perspective of homeless women. We conducted in-depth semistructured interviews with 15 homeless women to better understand their experiences of service encounters. Using a phenomenological method, 160 significant statements were extracted from participant tra...

Calculating structural complexity in phylogenies using ancestral ontologies
submitted by jdenh 36 minutes ago - Topic: Biology
Complexity is an important aspect of evolutionary biology, but there are many reasonable concepts of complexity, and its objective measurement is an elusive matter. Here we develop a simple measure of complexity based on counts of elements, incorporating the hierarchical information as represented in anatomical ontologies. Neomorphic and transformational characters are used to identify noveltie...
