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...

The main objective of this work is quantitative evaluation of porosity in carbon fiber reinforced polymers (CFRP) with the help of X-ray computed tomography (XCT). For this purpose two types of sample were compared. Industrial porosity sample was obtained from an aeronautical industry. Artificially induced porosity samples were created by drilling holes with diameter 0.2 mm and 0.3 mm in non-po...

A pilot study of 13 wells in Means oil field of the Permian basin, West Texas, established porosity-permeability relationships for the Permian Queen, Grayburg and San Andres formations. The optimized workflow used borehole image and conventional log processing with calibration to core data. This approach allowed the quantification of porosity and perme-ability heterogeneity in vuggy carbonate f...

Optimal reservoir management requires reliable reservoir performance forecasts with as little uncertainty as possible. There is a need for improved techniques for dynamic data intergration to construct realistic reservoir models by using geostatistical techniques. This paper gives a method to create porosity models that honor interpreted pore volumes from well test data. Well porosity data, sei...

In-stream structures contribute greatly to the biodiversity in streams and play an important role in restoring and protecting rivers. They usually have complex geometries. To evaluate their impact and effectiveness, computational models are increasingly used. However, how to faithfully represent them in computer models remains a challenge. Often, simplifications have to be made. This work evalu...

background: the classical supportive therapy for î² -thalassemia major consists of regular blood transfusion, iron-chelation therapy and specific treatment of the related complications. a balance between the maintenance of the highest possible level of haemoglobin and lowest possible level of iron accumulation in heart and liver give the best chance of survival and the best quality of life. met...

Reservoir characterization of W-field, onshore Niger Delta was carried out using petrophysical evaluation well logs. Three reservoir sand intervals (A, B, C) were identified and correlated across four wells (W1, W2, W3, W4) in W-field the gamma ray, while fluid identification each achieved resistivity log. The C interval selected utilized for interpretation penetrated at depths 11741-11945ft, 1...
