abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
It is commonly believed that collision protocols are impractical for very fast bus networks, owing to the constraints on the minimum packet length. In this paper, we present two collision protocols that contradict this opinion. These protocols are two representatives of the so-called Piggyback Ethernet family. They incur no synchronisa-tion overhead under very light load, and under heavy traac ...
A second order section such as the above can be realized in a number of ways; the one of concern here is the socalled 1-D form (see Reference 3). The second order 1-D form is shown in Figure 2. Based on this figure, we can obtain the following equations: m(k) e x(k) b B1 c m(k b 1) b B2 c m(k b 2) y(k) e A0 c m(k) a A1 c m(k b 1) a A2 c m(k b 2) Define T1 e bB1 c m(k b 1) b B2 c m(k b 2), T2 e ...
We study pfaffian analogues of immanants, which we call pfaffinants. Our main object is the TL-pfaffinants which are analogues of Rhoades and Skandera’s TL-immanants. We show that TL-pfaffinants are positive when applied to planar networks and explain how to decompose products of complementary pfaffians in terms of TL-pfaffinants. We conjecture in addition that TL-pfaffinants have positivity pr...
legal establishment of court is the birth of social life; each person should define him/herself against others offence or violation. when a society forms and the legal character appears, the thought of society refers to a person name prosecuting attorney who is the president of the court for defending his/her rights. prosecuting attorney remindterms such as court, crime and punishment. accordi...
the current study examined iranian undergraduate efl students’ willingness to communicate with regard to their vocabulary knowledge. in general, participants were somewhat willing to communicate in english. the total mean score of 730 university students’ perception of willing to communicate was 83.53 out of 135. results, regarding four parts of willingness to communicate, revealed that part...
food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
We present an in-place depth first search (DFS) and an in-place breadth first search (BFS) that runs in the restore model in linear time. To obtain our results we show several linear-time in-place graph transformations from one representation to another representation.
