Interception of extrasolar objects is one the major current astrophysical objectives since it allows gathering information on formation and composition other planetary systems. This paper develops a tool to design optimal orbits for interception these bodies considering effects different perturbation sources. The trajectory obtained by solving Lambert’s problem that gives required initial impul...

In this work we tested techniques suitable for a future validation of the RATP model to simulate transpiration and photosynthesis of mature olive trees under field conditions. Canopy architecture was characterised with an electromagnetic 3D digitiser and the software 3A. Although the capability of the software to deal with big data sets has to be improved, the system seems to meet the RATP requ...

The angular distribution of diffuse radiation was measured from May 1976 to May 1977 with a set of purpose-built actinometers. Radiance distributions for 98 overcast hours were fitted well by an expression similar to the conventional function for a 'standard overcast sky' (SOC). However, values of the coefficient b averaged 1.23, significantly smaller than for the SOC (b = 2). Expressions for t...

in order to study radiation use efficiency and radiation interception in intercropping of herb sweet basil and common bean, an experiment was conducted at the agricultural research station, ferdowsi university of mashhad, iran for the growing season of 2008. treatments were 1) sole crop of bean , 2) sole crop of sweet basil, 3) strip intercropping of bean and sweet basil (four rows bean and two...

When compared with access network interception, Lawful Interception of the Internet is both more difficult and much less mature. However, Internet interception is becoming increasingly more important as Law Enforcement Agencies find that access network interception is becoming less effective. Unfortunately, the most common approach to Internet interception has some fundamental weaknesses, which...

The light deficiency in the canopy is not the main factor limiting maize (Zea mays L.) production but the lower radiation use efficiency (RUE). Conservation tillage planting patterns were used to construct a sustainable agricultural system for soil protection and higher RUE. On these bases, we tried to create more uniform light distribution in crop canopy for increasing radiation use efficiency...

We examined the effects of structural and physiological acclimation on the photosynthetic efficiency of Scots pine (Pinus sylvestris L.) shoots. We estimated daily light interception (DLI) and photosynthesis (DPHOT) of a number of sample shoots situated at different positions in the canopy. Photosynthetic efficiency (epsilon) was defined as the ratio of DPHOT to the potential daily light interc...

this research was carried out in a reforest at shirvanagriculturecollegein two years (2005-2007). the aim of this research was to determine of canopy interception loss, throughfall and stemflow. four trees species were used including pinus nigra, cupressus sempervirens, robinia pseudacacia and platanus orientalis with three replications. the results showed that the amount of canopy interception...
