this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

this study was done to evaluate the effects of harvest time on some factor of ‘ahmadaqaie’ pistachio nuts in rafsanjan. in three consecutive years (2009-2012) during three stages of friut ripening (40, 70 and 100 percent of hulling), fruit was harvested and physiological and biochemical parameters were measured. the experiments were conducted as randomized complete block design with compound an...

.  Introduction Old trees are important and key elements of forest sites and are of great value in terms of forest management, reforestation, silviculture and ecology. Although old trees constitute a small percentage of forest trees, they account for a large share of forest carbon reserve and play a vital role in carbon storage. Understanding the how geographical and site distribution of thes...

Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction. Brazil nut (Bertholletia excelsa, Lecythidaceae) is one of the world's most economically-important NTFP species extracted almost entirely from natural fore...

Identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. In order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in Minoodasht region in Golestan province (north of Iran) were evaluated. Traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.

Mixed tree cropping systems have been proposed for sustainable nutrient management in the humid tropics. Yet, the nutrient interactions between intercropped trees have not been addressed sufficiently. In the present study we compare the temporal and spatial patterns of the uptake of applied N by four different tree crops in a mixed tree cropping system on a Xanthic Ferralsol in central Amazônia...

the importance of shea tree to the people of south-western nigeria cannot be over emphasized considering both the economic and environmental uses of the tree. however, efforts have not been made to propagate its production by the farmers as the shea tree still grows in the wild state. it would be worthwhile to investigate farmers’ perception of shea nut tree as an economic tree and their attitu...
