enzymatic deinking of xerox printed papers by commercial cellulase from aspergillus niger fungi was investigated. enzymatic treatment was done under constant condition of 0.1 percent enzyme based on oven-dried weight of pulp (102 unit per 100 gram oven-dried pulp), 15 min. treatment time, in four ph levels as 4, 5.7, 8 and 9. then, the effect of ph variation on the appearance and strength prope...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
this study was aimed to investigate the possibility of using magnesium hydroxide as an alternative for sodium hydroxide in deinking of newsprint and magazine mixture. the old newsprint and magazine mixture (onp/omg -70/30) was treated by magnesium hydroxide at three levels: 1, 1.5 and 2 percent (based on oven dried pulp weight), for 20 min. optical and mechanical properties and effluent cod loa...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
This experiment was conducted to evaluate the effects of different levels of dried lemon pulp (DLP) on performance, carcass traits, blood biochemical and immunity parameters of broilers. In this experiment 240 of broilers (Ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. Experimental diets included: 1) ...

in this research, the effect of ph onthe performance of nanobentonite -chitosan system (as dry strength additives) in hardwood chemi-mechanicalpulp (cmp) was studied.for this purpose, 3 levels of ph(5.5, 7, 8.5) and 3 levels of chitosan (0.75, 1.25 and 2% - based on oven dried pulp) in constant level of 0.3 nanobentonite(based on oven dried pulp) were applied.the atomic force microscopy(afm) im...
The present study was conducted to evaluate the effects of dried citrus pulp(0, 5, and 10%) and pectinase enzyme supplementation (0 and 2000 unit per kg) on feed intake, body weight gain, feed conversion ratio, nutrient digestibility and the internal organ size of broiler chickens. A total of 240 one day old male Ross 308 broiler chicks were used in a factorial arrangement (2×3) based on a comp...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
