The present study was carried out to determine the possible origins of sediments entering Taleghan Dam in northern part of Iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. This was performed by XRD analysis. To do so, first of all, sediment sampling points were positioned along the Taleghan River. The collected samples, after coding,...

intruduction: red beds have been widely studied by palaeomagnetic methods for what they can tell us about the history of sedimentary basins and their subsequent deformation (collinson, 1974, turner, 1979a,b and 1981, mccabe and elmore, 1989, elmor, et al., 1993 and 2000). this study has investigated the palaeomagnetism of the cambrian red sediments (dezou and dahou formation) of the eastern mar...

The Nayband Formation was measured and sampled in Parvadeh area, southern Tabas city. In this area, this formation has a thickness of 1410 m, dividing into four members, namely Gelkan, Bidestan, Howz-e-sheikh and Howz-e-khan. A total 573 samples were treated for Palynological analysis, and only 120 samples were productive. A total of 57 miospore taxa and 11 plant macrofossil were encountered. B...

microgastropod fauna from the upper devonian cephalopod bed and overlying lower tournaisian strata of the original reference section of the shishtu formation have been examined. twenty genera and one unknown genus have been identified. the original aragonite shells have been replaced either by pyrite or fluorapatite

BACKGROUND AND OBJECTIVES Staphylococcus aureus is an important pathogen and a frequent cause of infections associated with biofilm production in implantable medical devices. Biofilm production can be induced by sub-inhibitory concentrations (sub-MICs) of certain antibiotics, but few studies have researched this occurrence in S. aureus. In this study, we investigated the effect of sub-MICs of r...

BACKGROUND Microorganisms growing in a biofilm are associated with chronic and recurrent human infections and are highly resistant to antimicrobial agents. There are various methods to detect biofilm production like Tissue Culture Plate (TCP), Tube method (TM), Congo Red Agar method (CRA), bioluminescent assay, piezoelectric sensors, and fluorescent microscopic examination. OBJECTIVE This stu...

the soltan dam on the river soltan, a branch of tine river, is located about 19 km of mateur city in the northeast of tunisia. the dam is now under study and will be constructed in 2017. the soltan dam has been designed as an earth fill dam with homogeneous materials. the dam and its associated concrete structures are mainly founded on marl, shale and shale of lower miocene age, sandstone of th...

Sections of hyalinized laryngeal polyps stained with haematoxylin and eosin or Congo red can easily be confused with localized amyloid of the larynx. Several histological methods were applied to 61 specimens containing hyaline deposits or hyalinized tissues which included 36 laryngeal polyps. The results were compared with seven cases of localized amyloidosis of the upper respiratory tract and ...

purpose: to report a case of proteus syndrome with new ophthalmic findings not reported elsewhere. patient and findings: the patient is an 18-year-old girl with red lesions on hand and foot from birth and disproportionate growth of right upper and lower limbs from the first year of life. on examination, the patient has enlargement of the right upper and lower limb, macrodactyly, vascular malfor...

We analyse the rest–frame (U−V) colour–magnitude relation for 2 clusters at redshift 0.7 and 0.8, drawn from the ESO Distant Cluster Survey. By comparing with the population of red galaxies in the Coma cluster, we show that the high redshift clusters exhibit a deficit of passive faint red galaxies. Our results show that the red–sequence population cannot be explained in terms of a monolithic an...
