Advances in photogrammetry have eased the acquisition of high-resolution digital information from outcrops, enabling faster, non-destructive data capturing and improved reservoir modeling. Geocellular models for flow dynamics with in the virtual outcrop in siliciclastic deposits at different sets of sandstone facies architecture remain, however, a challenge. Digital maps of bedding, lithological contrast, spatial-temporal variations of bedding and permeability characteristics make it more easy to understand flow tortuosity in a particular architecture. An ability to precisely model these properties can improve reservoir characterization and flow modeling at different scales. Here we demonstrate the construction of realistic 2 D sandstone facies based models for a pragmatic simulation of flow dynamics using a combination of digital point clouds dataset acquired from LiDAR and field investigation of the Sandakan Formation, Sabah, ***, we present methods for enhancing the accuracy of outcrop digital datasets for producing high resolution flow simulation. A well-exposed outcrop from the Sandakan Formation, Sabah, northwest Borneo having a lateral extent of 750 m was chosen in order to implement our research approach. Sandstone facies and its connectivity are well constrained by outcrop observations, data from air-permeability measurements, bilinear interpolation of permeability, grid construction and water vector analysis for flow *** proportions were then enumerated in terms of static digital outcrop model(DOM) and facies model based on sandstone facies bedding characteristics. Flow simulation of water vector analysis through each of the four sandstone facies types show persistent spatial correlation of permeability that align with either cross-bedded orientation or straight with more dispersion high quality sandstone(porosity 21.25%-41.2%and permeability 1265.20-5986.25 mD) and moderate quality sandstone(porosity 10.44%-28.75% and permeabili

This study examines the relationship among independent boards of directors, board size, managerial share ownership （MSO）, and earnings quality. The study of these relationships is controlled by firm size based on a sample of 114 companies listed on the Tehran Stock Exchange （TSE） for the period from 2008 to 2010. The results demonstrate that there was an insignificant positive relationship among independent boards of directors, managerial ownership, and earnings quality. Subsequent analysis shows an insignificant negative relationship between board size and earnings quality. It also provides evidence of the negative relationship between firm size as a control variable and earnings quality. This can be attributed to the fact that large firms are claimed to be politically sensitive and thus have the incentive to lessen variances in changes in their reported earnings.

Future need of globalization in business is no longer focused on the local transaction; instead, it has involved many countries so as to affect the exchange rate of rupiah against foreign currencies. As a result, differences in the exchange rate will lead to foreign exchange, be it a foreign exchange gain or foreign exchange losses. Exchange rate used at the beginning of the transaction is the exchange rate on the transaction, but in Indonesian currency transactions, what is often used is the exchange rate issued by the Directorate General of Taxation （DGT）. If at the end of the period, a balance of foreign currency still exists, then it will be adjusted using a fixed rate or an exchange rate of Central Bank of Indonesia. The results showed that the treatment of foreign exchange at the fishery company was using both the exchange rate allowed in the accounting and taxation regulations in Indonesia. The balance of transactions is related to export, be it a balance of accounts receivable on the sale of the outstanding balance of exports and export freight carried at the exchange rate adjustment of Central Bank of Indonesia, subsequent transactions relating to the purchase of imports were adjusted to a fixed exchange rate, which means that the balance payable on imports will continue to use the exchange rate at the beginning of the transaction
