In the testing of food quality and safety, we contrast the contents of the newly proposed food (genetically modified food) against those of conventional foods. Because the contents vary largely between crop varieties and production environments, we propose a two-sample test of substantial equivalence that examines the inclusion of the tolerance intervals of the two populations, the population o...

in recent years, biotechnology has provided the possibility of creating genetically modified (gm) organisms by transferring genes from sources such as viruses, bacteria, animals, and plants into usually unrelated species. this ability to overcome insurmountable physiological barriers by exchanging genetic materials among all living organisms is a double-edged sword. on the one hand, it allows t...

background: the classical supportive therapy for î² -thalassemia major consists of regular blood transfusion, iron-chelation therapy and specific treatment of the related complications. a balance between the maintenance of the highest possible level of haemoglobin and lowest possible level of iron accumulation in heart and liver give the best chance of survival and the best quality of life. met...

the present study was conducted to investigate the effect of modified cloze procedure on writing proficiency of iranian intermediate efl learners. to fulfill the purpose of the study, 110 participants studying at semnan university majoring in english literature were tested on celt proficiency test. 65 participants who were found to be homogenous were selected and assigned randomly to two groups...

a sodium dodecyl sulfate modified carbon paste electrode (sds/cpe) was developed in this work based on the surface modification method. the modified electrode was prepared by immersing sds/cpe in a nickel nitrate solution. this electrode showed a strong accumulation ability toward nickel ions. then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 v (vs. ...

world population has already exceeded 6.5 billion, out of which about 850 million (13 percent) are undernourished. with the current growth rate, the world community faces even a greater challenge of hunger and food security as the estimated the population will catch 9 billion by the year 2050 with doubled needs for food. at the same time, preservation of biodiversity, stopping deforestation and...

the ability of natural clinoptilolite and its modified forms were studied for removal of pahs from n-paraffin. surfactant modified zeolite (smz) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. ag+, fe3+…). natural clinoptilolite and its cation exchanged...

a thin film of epinephrine (ep) was electrochemically deposited on the surface of glassy carbon electrode previously activated in nahco3 solution. the cyclic voltammograms of the modified electrode indicate that the surface confined ep are strongly dependent on the solution ph, as expected for quinone/hydroquinone functionalities. the ep-modified glassy carbon electrode exhibited catalytic acti...

nec is inflammatory necrosis of intestine with most common site being terminal ileum and ascending colon in preterm babies (1). the condition is typically seen in premature infants, and the timing of its onset is generally inversely proportional to the gestational age of the baby at birth, i.e. the earlier a baby is born, longer is the time of risk for nec in premature babies. the incidence of ...
