The environmental physiology of tomato (Lycopersicon esculentum Mill. cv. Heinz-6004) and black or eastern black nightshade (Solanum nigrum L. and Solanum ptycanthum Dun.) competition
… species. Eastern black nightshade responded to self shading by increasing specific leaf area.

Differential power processing for increased solar array energy harvest
… common and predictable sources of mismatch are self-shading and diffuse masking. Both these shading effects are influential in designing arrays. The simulation model is used to compare the impact of these two effects. Annual solar data, given in hourly measurements, is used to simulate the …

CHANGES IN LEAF MORPHOLOGY, PHOTOSYNTHESIS AND NITROGEN CONTENT IN TWO COASTAL SHRUBS
… initially and then declined with age due to self shading. Nitrogen content was highest during spring. Seasonality and leaf age had unique effects on the two study species. Understanding senescence adaptations of these two shrubs can help explain their abundance in coastal ecosystems.

Marine optics: field radiometry
… effects by deployment superstructures, self-shading and surface roughness for in{water measurements. Applications of in situ optical radiometric measurements, including the development of algorithms for the determination of the concentration or the apparent optical properties of seawater …

Distribution of leaf dissection and sclerophylly along microhabitat gradients in pteridophytes of the Cape peninsula
… because of lower metabolic costs or to reduce self-shading.

Characterising responses of the seagrass Posidonia Sinuosa to changes in light availability
… was validated experimentally by in situ shading at a shallow (3- 4 m) and deep (7- 8 m) site with light (LS; 87% of ambient light), moderate (MS; 27%) and heavy shading (HS; 9% at shallow only). After 106 d, significant shoot loss had occurred but complete loss did not occur after 206 d. …

The development and decline of phytoplankton blooms in the southern Benguela upwelling region
… below the 1% light level indicating that self-shading is an important factor limiting primary production in the Benguela upwe!ling system. The temporal scale of phytoplankton bloom development was investigated in terms of changes in chlorophyll � concentrations in the euphotic zone. The …

Mashrabiya in passive cooling: Integrating Concepts of Mashrabiya into an Innovative Ceramic Evaporative Screen
… for passive cooling strategies is urgent. While shading methods are commonly used to reduce sun exposure, existing systems rarely succeed in combining evaporative cooling and shading in a single component. Most approaches prioritise one function at the expense of the other or demand excessive …

Influencia de la luz y la sequía estival en la respuesta funcional de brinzales de Quercus petraea (Matt.) Liebl. y Quercus pyrenaica Willd. : implicaciones para la regeneración
… number of basal sprouts resulting in reduced self-shading compared to pyrenean oak. Survival was though similar or lower in sessile oak than in pyrenean oak in several plantations carried out in gaps, clearings and Scots pine stands close to a beech-oak forest in Montejo de la Sierra (NE …
