the effect of different mozzarella cheese manufacturing methods, i.e. direct acidification (da), starter culture (sc) and their combination method (cm) on physicochemical, yield, texture, color and sensory properties of the product were compared. chemical analyses of samples revealed that the sc cheese had higher fat, moisture, ash, titratable acidity, actual and adjusted yields and fat recover...

Energy consumption is considered as a critical issue in wireless sensor networks (WSNs). Batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. An efcient solution to improve energy consumption and even trafc in WSNs is Data Aggregation (DA) that can reduce the number of transmissions. Two main challenges for DA are: (i)...

fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...

Originating from Vygotsky’s Sociocultural Theory, dynamic assessment (DA) proposes a novel approach to second language acquisition (SLA) research according to which a dialectical relationship is envisaged between instruction and assessment. Although DA has been applied to some areas of SLA, there are areas, such as interlanguage pragmatics (ILP), that have been neglected.  To address the issue,...

Because of participation in many aspects of human life, and due to oxidation-sensitive characteristics of dopamine (DA) and arachidonoyl dopamine (AA-DA), the necessity of biocompatible carrier to keep them against oxidation is of importance. In this work, we explored the putative binding sites of DA and AA-DA to -lactoglobulin (BLG) as potent carrier. Docking results identified the binding si...

when the number of training samples is limited, feature reduction plays an important role in classification of hyperspectral images. in this paper, we propose a supervised feature extraction method based on discriminant analysis (da) which uses the first principal component (pc1) to weight the scatter matrices. the proposed method, called da-pc1, copes with the small sample size problem and has...

CoFe2O4 magnetic nanoparticles were modified by dopamine (DA) and ascorbic acid (AA) as anchors. Separation of the DA and AA using CoFe2O4 magnetic nanoparticles have been studied by investigating the effects of pH, concentration of the DA and AA, amount of adsorbents, contact time, ionic strength and temperature. The mechanism of adsorption was also studied. The adsorption of DA and AA to the ...
