abstract:â green spaces, especially urban gardens have been a subject of study in many countries for a long time, but the subject has been mostly overlooked in iran. therefore, this study tries to analyze the changes in land use and how we can protect green spaces (gardens) in jahrom in line with sustainable development in 1996-2006. the data in this study were collected through local investiga...

in this research, moisture sorptions of sayer date were determined at 20, 30, 40 and 60°c, using the standard static gravimetric method developed by the european cooperation project cost 90. several mathematical models, namely gab, bet, iglesias & chirif and halsey were employed to fit the experimental data through non-linear regression. results indicate that equilibrium moisture content increa...

objective: being able to cause disease in human, herpes simplex viruses (hsvs) clinically demonstrate themselves as intra-oral, extra-oral or recurrent lesions. the existing acyclovir has the selective anti-herpetic drug to control hsv infections. due to emerged resistance to this drug and limitations of using it in especial situations, there is a need for alternative treatments such as availab...

global concern of protection of the environment has led to researches on the effects of plants, natural extracts and organic materials to help maintain the postharvest quality of horticultural crops. throughout the present study, the effects of such natural products as: mint, thyme, savory, rosemary extracts, s-carvone, and humic acid on postharvest life of cut rose flowers, and the potential o...

in this work, an optical sensor for detection of ascorbic acid is described. the sensor is fabricated by casting and spin-coating silica sol-gel doped with 2,6-dichlorophenol indophenol on the glass plates. the sols are in turn obtained by acidic hydrolysis of various precursors such as tetraethoxysilane, triethoxymethylsilane and triethoxyoctylsilane in the presence of 2,6-dichlorophenol indop...

japan is a region of active plate tectonics, well known for its japanese trench a geological feature evolving as a result of north pacific (np) oceanic plate pushing and sub-ducting underneath the north american (na) plate. multiple plate tectonics have been continuously recorded in the region since 1979 by the network of gps stations called geonet. the network operating and monitoring more tha...

in this research, temporal and spatial behavior of siberian high (sh) was studied at the level of 1000 h.pa. this study has been done using daily data of geo potential height at 12 gmt in ncep/ncar database with spatial resolution of 2.5ã—2.5 degree in a 55 years period including 20089 days from january, 1st, 1951(dey, 11th, 1329) to december, 31st,2005(dey, 10th,1384). at first, the mean geo p...

two simple visible spectrophotometric methods are developed and validated for the quantification of modafinil using 1,2-naphthoquinone-4-sulphonic acid (nqs method) and 2,4-dinitrophenol (dnp method) as analytical reagents. the nqs method involves the reaction of modafinil with 1,2-naphthoquinone-4-sulphonate in alkaline medium at room conditions to form a yellow colored product exhibiting maxi...

background and purpose   methods:   results:   conclusion:

to evaluate the effect of salinity on some quantitative and qualitative characteristics of spring rapeseed cultivars, an experiment was conducted in the greenhouse conditions at yasoujuniversityas a factorial with three replications. four salinity levels (1.92 (as control), 9.87, 19.6 and 21.94 dsm-1 (nacl and cacl2 with ratio 20 to 1 in hoagland solution)) as a first factor and eight cultivars...
