abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

Toprak erozyonu toprak degredasyonuna neden olan tehditlerden birisidir. erozyonunun koşullarını, bitki verimini, biyoçeşitliliği ve insan beslenmesini tehdit ettiği bilinmektedir. kaynaklarının sürdürülebilirliğini şeker pancarı, patates, havuç, sarımsak gibi bitkilerin hasatı sırasında oluşan kayıpları etkilemektedir. Bu araştırmanın amacı hasatının olduğu kaybını, kaybı etkileyen faktörleri,...

We used an existing analytical model of stemwood growth in relation to nitrogen supply, which we describe in an accompanying paper, to examine the long-term effects of harvesting and fire on tree growth. Our analysis takes into account the balance between nitrogen additions from deposition, fixation, and fertilizer applications, and nitrogen losses from stemwood harvesting, regeneration burning...

abstract due to transmission losses and lack of initial flow, flood routing in ephemeral streams is not possible with common methods and it is necessary the flood routing models have been developed for these streams. therefore in this study a computer model for natural river cross section has been developed in that after linearization of partial differential equations of unsteady none uniform f...

Previous studies have suggested that excessive losses of FVC and FEV1 were occurring in Vermont granite workers despite the fact that mean quartz levels existing in the industry were below the current OSHA standard of 100 ,ug/m3. We reexamined these losses in granite workers over an 8-year period, testing the workforce biennially from 1979 to 1987. All workers, including stone shed, quarry, and...

grown in California because of its high productivity, wide soil adaptability, seedless fruit, and versatility for use in different grape and raisin products. About 95 percent of California raisins are currently produced from ‘Thompson Seedless’ grapes, followed by ‘Fiesta’ (3 percent) and ‘Zante Currant’ (1.5 percent). The remainder are produced from ‘DOVine,’ ‘Muscat of Alexandria,’ “Sultana” ...
