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 ...

background:  despite the introduction of different techniques for meniscal repair, no single procedure is superior in all situations. the new method for meniscal repair named “ modified outside-in technique ” aims to achieve higher primary fixation strength by an alternative suture technique as well as avoid disadvantages of outside-in, inside-out, and all-inside suture procedures. additionally...

the paper is focused on the formation of hydroxyapatite nanoparticles (hap) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of na-polyacrylate (paa) as an anionic polyelectrolyte. it is shown that paa, can be incorporated into the individual inverse microemulsion droplets. the m...

the present study was conducted to investigate the effect of modified cloze procedure on writing proficiencyof iranian intermediate efl learners. to fulfill the purpose of the study, 110 participantsstudying 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 twogroups of ...

in this paper, a nanostructured modified electrode was fabricated by incorporating of 2,2′-[1,9-nonanediylbis(nitriloethylidyne)]-bis-hydroquinone (nnh) as a newly synthesized modifier and tio2 nanoparticles to the carbon paste (mtcpe) and then was used for the electroanalysis of epinephrine (ep). the electrochemical studies were carried out by using cyclic voltammetry, chronoamperometry and di...

Genetically engineered protein block polymers are an important class of biomaterials that have gained significant attention in recent years due to their potential applications in biotechnology, electronics and medicine. The majority of the protein materials have been composed of at least a single self-assembling domain (SAD), enabling the formation of supramolecular structures. Recently, we dev...

Traceability of GMO food and feed is a growing request among the European populations and the European Community has responded by providing a complex set of EC Regulations on GMO traceability, detection and labelling, to ensure that the general public is able to make an informed choice about the food they eat. Despite the efficiency and sensitivity of modern GMO detection methods, the regulatio...
