in this study, in order to constitute polyelectrolyte multilayers (pem) using layer-by-layer nanotechnology, recycled fibers were subsequently treated with cationic starch (cs) and anionic starch (as) multi-layers each layer conducted at neutral ph for 10 minutes. also, to compare with mechanical of refining, the pulp was refined for 25 minutes to the freeness of about 291 ml.csf using valley b...
a split plot factorial experiment based on randomized block design in four replications was performed in order to study the effect of three levels of compost (zero, 10 and 20 ton dry matter/ha), in main plots and three levels of nitrogen (zero, 100 and 200 kg/ha pure nitrogen) and three levels of phosphorous (zero, 60 and 120 kg/ha p2o) on corn yield. the effect of compost on different characte...
In order to investigate mineral manganese forms and their relations with plant responses, 22 soil samples from Fars province (0-20 cm) were in a greenhouse experiment filled in 3 liter pots, and soybean (Glycine max (L.) merr.,CV.Williams) was grown for 7 weeks. Chemical forms of manganese were determined in soils by warden and Reisenauer sequential extraction method (readily soluble, weakly ad...
this study was conducted to evaluate the relative bioavailability value of mn proteinate and mn oxide in broiler chicks. a total of 432 day-old cobb 500 commercial male broiler chicks were randomly distributed into nine treatments with eight replicate pens of six chicks each. in a completely randomized design experiment with a 2×4 factorial arrangement of two manganese sources (proteinate and r...

introduction: median nerve (mn), one of terminal branches of brachial plexus, is commonly associated with several variations. this research aimed to review the literature related to the variations of mn from axillary region to cubital fossa. methods: we searched google scholar, science direct, springer, and pubmed electronic databases to compile reports related to the variation of mn published ...
Human corneal epithelial (HCE-T) and human lens epithelial (SRA01/04) cells derived from the human eye were exposed to 60 gigahertz (GHz) millimeter-wavelength radiation for 24 h. There was no statistically significant increase in the micronucleus (MN) frequency in cells exposed to 60 GHz millimeter-wavelength radiation at 1 mW/cm² compared with sham-exposed controls and incubator controls. The...
Children with acute lymphoblastic leukemia (ALL) and high hyperdiploidy (>50 chromosomes) are considered to have a relatively good prognosis. The specific extra chromosomes are not random; extra copies of some chromosomes occur more frequently than those of others. We examined the extra chromosomes present in high hyperdiploid ALL to determine if there were a relation of the specific extra chro...
Three accurate X-ray diffraction experiments (Mo Kalpha, T = 190, 240 and 298 K) were carried out to track the temperature dependence of the electron density in the cubic perovskite potassium manganese trifluoride, KMnF3, from room temperature to just above that of the phase transition to the tetragonal structure (186 K), and to correlate the parameters of the critical points with the phase-tra...
