prediction of the waves’ specifications that is one of the key factors effective on transformation ofcoasts, production of renewable energies and design of marine structures, has always been importante.height of the waves is one of the most important and effective parameters of the wave. differentfactors are effective in variation of the waves’ height. in this research, variation in waves heigh...

awareness of the presence of the accessory renal artery in kidney transplant, treatment of renal artery stenosis, clinical assessment of renal vascular hypertension, radiology and angiography interventions is very helpful. in 30% of cases the accessory renal artery is separated from the abdominal aorta and in most cases, this artery along with the main artery entered to the kidney through the h...

background: cutaneous and visceral leishmaniases are present in fars province in the south of iran. the current study aimed to evaluate the inter- and intragenic diversities of leishmania species isolated from patients with leishmaniasis in fars province, using pcr-based analyses and dna sequencing of  the n-acetylglucosamine-1-phosphate transferase ( nagt ) gene. methods: clinical samples were...

dental anatomical variations play a significant role in the diagnosis and a successful treatment outcome in endodontics. it is essential for the clinician to have a clear picture and understanding of the pulpal anatomy and its variations. in a mandibular second premolar, it is rare to find extra roots and canals. the aim of the present article is to report a case about the successful diagnosis,...

we report a rare case of a two-rooted maxillary central incisor, stressing the importance of three-dimensional imaging in treatment planning and conservative approach of management. endodontic treatment of this central incisor was carried out with a successful outcome.

case presentation a 30-year-old male patient with a history of severe, throbbing, constant pain in the lower mandibular molars was referred to the department of endodontics of hamedan dental university. the patient’s medical history was noncontributory. the buccal object rule (same-lingual opposite-buccal technique) confirmed the additional root as a distolingual root (radix entomolaris). follo...

sensitivity analysis to determine variations in evapotranspiration is much important considering a known variation in one of climatic variables. in this study, sensitivity of evapotranspiration from penmann-mantith, penmann-kimberly (1996), penman-kimberly (1972) and penmann (1984)  and hargrivs (1985) approaches to three climatic variations (maximum temperature, wind speed, solar radiation) wa...

mitochondria1 dna (mtdna) control region sequences were analyzed to evaluate the population genetic structure of persian sturgeon (acipenser persicus) in caspian sea. a total of 45 specimens were collected from the different locations of the caspian sea. mtdna control region was amplified using pcr. direct sequencing was performed according standard method. the results showed that 12 haplotypes...
