the berriasian-valanginian fahliyan formation forms one of the giant reservoirs in the subsurface of the abadan plain, onshore iran. a detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the fahliyan formation in this field. the fahliyan formation has been influenced by three diagenetic e...

the aim of this research was the geochemical assessment of the groundwater quality and the evaluation of the distribution pattern of fluoride concentration in water resources of the region and their connection with the prevalence of dental fluorosis occurrence in the study area. to achieve to this goal six sediment and 22 water samples were taken and analyzed. fluoride and phosphorous concentra...

This paper studies the security of a recently-proposed chaos-based image encryption scheme, and points out the following problems: 1) there exist a number of invalid keys and weak keys, and some keys are partially equivalent for encryption/decryption; 2) given one chosen plain-image, a subkey K10 can be guessed with a smaller computational complexity than that of the simple brute-force attack; ...

The addition of adrenaline 5 mug/ml, 1 : 200 000 to 1% etidocaine hydrochloride administered extradurally (L2-3) shortened significantly the onset time for sensory blockade, particularly with respect to the spread of the analgesia from the injection site, and shortened the already rapid onset of motor block. Etidocaine hydrochloride 1% plain caused a slower onset of block, laster longer and pro...

The study was conducted to evaluate the differences in results obtained for assays of ionized calcium (iCa) by plain and heparinised blood sample and observe for any errors in values done by ion selective electrode (ISE) method and to determine which of the collection methods could be ideal and reliable. 49 samples of heparinised and 31 plain blood samples were analyzed at lab services, Apollo ...

Plain abdominal radiographs are commonly requested for acute medical emergencies on patients with non-specific abdominal symptoms and signs. In this study 131 plain abdominal radiographs performed on the day of admission were prospectively analysed. In only 16 cases (12%) the reasons for requests conformed to the recommended guidelines by the Royal College of Radiologists. The reason for the re...

background: ankle fractures, especially those resulting from external rotation mechanisms are associated with injury to the distal tibiofibular syndesmosis. some authors have recommended performing ct scanning after open ankle surgery to evaluate the reduction of syndesmosis. in this current study, we aimed to investigate the sensitivity of plain radiography in diagnosing syndesmosis malreducti...

izeh plain is a sedimentary plain situated at northeastern part at khuzestan province, iran where according to some partial investigations carried out in 2007, 54 settlements from epipalaeolitic and early neolithic ages were discovered there. henry wright, who had explored throughout this settlement before islamic revolution, implies that only 30 percent of piedmonts were completely investigate...

background: rafsanjan -noogh- anar's plain (54°, 52′- 56°, 34′ longitudinally & 29°, 51′- 31°, 31′ latitudinally) is one of the iran's plains located in sub- basin of daranjir desert. anar's plain is located at the lowest part of rafsanjan -noogh- anar's plain. according to the geological and field studies of the area, the presence of west and east mounts and deposits re­sulting from evaporatio...
