this study was performed with objective land cover change prediction (forest, agriculture, residential and orchard) using logistic regression and markov chain in the gis environment in east of mazandaran province. land cover change detected using satellite imageries belonging to the years 1987 and 2001. transition potential modeling was conducted using a logistic regression. seven variables (de...

We introduce the Orchard crossing number, which is defined in a similar way to the well-known rectilinear crossing number. We compute the Orchard crossing number for some simple families of graphs. We also prove some properties of this crossing number. Moreover, we define a variant of this crossing number which is tightly connected to the rectilinear crossing number, and compute it for some sim...

This paper analyzes the characteristics of the NPS nitrogen pollution of the groundwater in Guoyuan Village, Pudong District, Shanghai. And the associated effects on the surface and groundwater around the study area are discussed in detail based on the successive observed data, DNDC and L-THIA model. The results show that both of the surface and groundwater are polluted so seriously that they a...

High-density apple (Malus domestica) orchard management techniques and productivity were evaluated on an old orchard replant site in North Carolina. Trees were planted at 5 × 10 ft (1.5 × 3.0 m), giving a tree density of 871 trees/acre (2152 trees/ha). Well-branched ‘Smoothee Golden Delicious’ trees on ‘Mark’ rootstock were planted in 1990. Orchard-management factors which increased cumulative ...

The effects of supplemental mass pollination (SMP) were studied in two Pinus sylvestris seed orchards differing in pollen production. Pollen was dusted over the whole tree during the period of peak female receptivity using a pressurized backpack sprayer. The success of SMP was assessed by means of allozyme markers. In the orchard with high pollen production, detectable differences in SMP succes...

A study was designed to evaluate the micronutrients status of soils of district Palandri, Azad Kashmir and to correlate the micronutrients with Physico-chemical characteristics of soil as well as to categorize the soils as high, medium and low in Cu, Zn, Fe, Mn and HWS B. Soil samples were collected from thirty wheat fields and thirty apple orchard soils during 2003. None of the soil sample was...

Video multicast is an important application for P2P networks, which can benefit from the load repartitioning and large scale distribution properties they have to offer. In this context, the Orchard algorithm was developed in 2007, with an aim to build a P2P system meeting video multicast requirements. However, Orchard suffers from a slow overlay construction and a potentially high end-to-end de...

Orchard evapotranspiration (ET) is a complex flux which has been the subject of many studies. It often includes transpiration from trees, cover crops and weeds, evaporation soil, mulches other orchard artefacts. In this study we investigated contribution floor evaporative fluxes to whole ET focusing on dynamics understorey vegetation currently not well known. Data partitioning into its constitu...
