a rare case of squamous cell carcinoma ex pleomorphic adenoma in maxillary sinus is presented. the patient is a 50-year-old woman presenting with a slow-progressive swelling in left side of her face that she has noticed 2 years earlier. the lesion was not painful and caused asymmetry and mild exophthalmos. microscopic examination revealed that the tumor was composed of two components partly of ...

in a voice conversion system speech signal of a speaker (i.e. source speaker) is modified so that it sounds as if it had been pronounced by b speaker (i.e. target speaker). this process, sometimes, is called speaker conversion (changing speaker identity). achieved signal from speaker conversion system is desired to have high quality and very natural. to satisfy this, three major methods are pro...

Abstract: transformation temperature and different ferrite morphologies in one Nb-microalloyed (HSLA) steel has beeninvestigated. Three different austenite grain sizes were selected and cooled at two different cooling rates for obtainingaustenite to ferrite transformation temperature. Moreover, samples with specific austenite grain size have beenquenched, partially, for investigation on the mic...

trehalose (a-d-glucosyl-[1,1]-a-d-glucopyranoside) is involved in mechanisms that coordinate metabolism with plant growth adaptation and development. the main objective of the current work was to find out whether trehalose feeding affects the expression of two genes involved in photosynthesis: one gene coding for photosystem1 subunit h (ps1-h) and the other for the light harvesting complex b1 (...

it has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...

it is a challenge for a farmer with limited resources to decide on the production of commodities and investment in the farm. transformation of smallholder subsistence agriculture, to market oriented value addition based agriculture is vital for poverty reduction in ethiopia. this study was initiated to explore the factors which contribute for the adoption of improved wheat and pepper varieties ...

modernization as a process also affects the way a society thinks, its attitudes, beliefs, food, dress habits, and cultural patterns at the level of individuals, and as the individuals can be seen as units of the society. in this study, an attempt has been made to understand the consequences of modernization in the traditional housing pattern as reflected in the changes in kitchen. for the prese...

microbial steroid biotransformation have found wide-reaching application for the production of more precious and functionalized compounds due to their high regio-and stereoselectivity. in this study, the possibility of using filamentous fungi aspergillus brasiliensis cells in the biotransformation of progesterone (i), a c-21 steroid hormone was studied for the first time.the fungal strain was i...

genetic transformation studies were carried out to standardize a protocol for agrobacterium -mediated genetic transformation of three economically important strawberry (fragaria x ananassa duch) cultivars kurdistan’, camarosa’, and ‘paros’. shoot regeneration frequency 72, 65 and 30% was obtained on ms (1) basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa, kurdistan and paro...
