This paper describes the foraminiferal associations along with presentation of three new agglutinated conical species to construction biozonation framework in Mahallat region central Iran. The stratigraphic distribution benthic foraminifers is used characterize assemblage zones that are ascending order: rotaliids-valvulinids Assemblage Zone, alveolinids-coskinolinids and nummulitids-discocyclin...

mahallat hot springs located in the northeast of mahallat, in central iran. there are 6 main hot springs namely shafa, abejoush, donbeh, soleimanie, hakim and soda. in this research, geology, physico-chemical characteristics and petrography of basement rocks of these hot springs have been investigated. the results show that hot springs have an average temperature of 45°c and acidic to neutral p...

Several methods have been developed for gold exploration in the past, among which biological base method is known to be the most efficient with least expenses. This method can also be used for latent gold prospects exploration. In the present study, the possibility of applying Bacillus cereus frequency in soil as a biological marker was investigated for the exploration of latent gold prospectin...

research was carried out in 2007 on 7 native summer-ripening apple cultivars grown in kamal abad karaj research station. the 16 year-old plants were grafted onto seed rootstocks. the cultivars were ghandak-e-kashan, golab-e-isfahan, golab-e-kohanz, mashad, assali, ghermez-e-rezaieh and a new cultivar--koli-e-mahallat (syn. escr). the aim of the study was to identify changes in qualitative and q...

the activity concentrations of 226ra, 232th, 40k and 137cs in water and sediment samples from hot springs of mahallat and  soil samples from their neighboring environs  have been determined using two high resolution high purity germanium (hpge) detectors with relative efficiencies 38.5% and 55%. the activity concentrations of 226ra, 232th, 40k and 137cs in sediment samples from hot spring donbe...

thrips specimens were collected in the year 2014 on different ornamental plants from mahallat (markazi province), iran. in this study, 11 species in six genera and three different families of thysanoptera were collected and identified. the scientific names of thrips species are as follow: melanthrips knechteli, m. pallidior, frankliniella intonsa, f. occidentalis, microcephalothrips abdominalis...

carnation (dianthus caryophyllus) can be infected by several viruses that some are specific to carnation flowers. vegetative propagation of carnation, can easily disperse viruses by infectied cuttings. during the year 2007, viral-like symptoms were observed on carnation in mahallat greenhouses. 142 suspected samples from glass houses, with symptoms of reddish- purple flecks and spots on leaves,...

Background: High level radiation areas have been recognized on various parts of the earth. Mahallat hot spring region is one of these areas. Study of exposure in these areas can be helpful in investigating the effects of ionizing radiation. Internal and external exposure to the staff was studied. Materials and Methods: Used materials and instruments include: RSS-112 ionizing chamber fo...
