The yield of any crop depends on the capacity a plant canopy to intercept and efficiently use sunlight, which is dependent architecture viz., leaf size, shape angle, number leaves branches, geometry row orientation, spacing, geometry, density, etc. amount distribution area in determine way, by which, photosynthetic active radiation intercepted consequently it influences photosynthesis yield. ba...

Direct seeded canola (Brassica napus L.) has become increasingly popular in China’s key canola-producing regions. The studies on the K response of direct-seeded performance are limited. This research aimed to investigate utilization efficiency and canopy radiation interception rate direct winter at various application rates. Two seasons field trials were done with five levels (0, 75, 150, 225...

As HTTPS deployment grows, middlebox and antivirus products are increasingly intercepting TLS connections to retain visibility into network traffic. In this work, we present a comprehensive study on the prevalence and impact of HTTPS interception. First, we show that web servers can detect interception by identifying a mismatch between the HTTP User-Agent header and TLS client behavior. We char...

Crown porosity influences radiation interception, air movement through the fruit orchard, spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop an accurate and reliable methodology based on transmitted radiation measurements to assess the porosity of traditional olive trees under different pruning treatments. Transmitted radiation was employed a...

Mountainous areas with rugged terrains are widely distributed around the world. Remotely sensed values of the fraction of absorbed photosynthetically active radiation (FAPAR) suffer from the effect of rugged terrain. In this study, the effect of rugged terrain was incorporated into the FAPAR model based on recollision probability (FAPAR-P), which was improved in two aspects: calculating the sky...

Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in post-harvest. The leaf area measurement fundamental plants because leaves are directly related several processes such as transpiration, radiation interception CO2 fixation that enable plant grow. objective work was determine an allometric equation for estimating lisianthus from linear di...

© The Ecological Society of America www.frontiersinecology.org T is a crucial need to understand ecological water balances, both in the present and in the future. This balance is currently shifting, as economies rapidly develop and urbanization accelerates (Hubacek and Sun 2005). In the future, global climate change and the resulting uncertainties will only add to the urgency of finding accurat...

Research into the possibility of picking up the electromagnetic radiation originating from video display units (VDUs) made clear that this type of information theft can be committed very easily [1]. It is not only this type of equipment which is vulnerable to interception at a distance; experiments on eavesdropping RS-232 cable signals prove that it is possible in some cases to intercept data s...

A common perception is that cancer risk reduction is passive, such as not smoking. However, advances in the understanding of cancer biology and in cancer treatment modalities suggest that it is now timely to consider anew cancer risk reduction by active, including pharmacologic, approaches. Risk avoidance approaches are certainly important, but other approaches are important as well, as exempli...
