in the present work, an adsorptive stripping voltammetric method using a hanging mercurydrop electrode (hmde) was described in order to determine the ultra trace of thiosemicarbazidein different real samples. the method is based on accumulation of thiosemicarbazide on mercuryelectrode. the potential was scanned to the negative direction and the differential pulse strippingvoltammograms were rec...

This research addresses the extraction and recovery of nickel ions from real electroplating wastewater using SLM process. The process involves three main phase system which are feed, organic and stripping phase. The feed phase containing the nickel electroplating wastewater whereas the organic phase containing the liquid membrane which was immobilized in the membrane support. The liquid membran...

In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...

In the liquid liquid extraction (LLE) the extraction of rhodamine B (RB) from aqueous solutions by using 0.8M phenol in xylene was studied. The influencing parameters such as the effect of pH of the aqueous phase, the effect of extractant concentration, the effect of diluents and the stripping reagents has been investigated. The maximum extraction efficiency was obtained at pH 1±0.1 and the max...

Started from the very beginning, Stemming has been playing significant roles in several Natural Language Processing Applications such as information retrieval (IR), machine translation (MT), morph analysis and deciding the part of speech (POS). Several stemmers have been developed for a large number of languages including Indian languages; however no work has been done in Kokborok, a native lan...

In this paper, we focus on ram-pressure stripping and evaporation of disk galaxies in and around a cluster. We show that the evolution of the disk surface density affects the efficiency of ram-pressure stripping of galaxies at z ∼ 1. We also consider the saturation of thermal conduction in detail and show that it cannot be ignored at larger radii of a cluster, which makes the time-scale of the ...

| We introduce a new multiaccess coding strategy called stripping CDMA for a LOOK AWGN channel. Stripping CDMA can be viewed as a generalization of the regular CDMA scheme to one that can achieve arbitrarily high bandwidth eeciency. It can also be viewed as a modiication of the pure stripping scheme to one that is suited for multiaccess channel with bursty users. In this scheme, each user is sp...

To speed up the rendering of polygonal meshes, triangle strips are commonly used to reduce the number of vertices sent to the graphics subsystem by exploiting the fact that adjacent triangles share an edge. In this paper, we present an improved adjacency data structure for fast triangle stripping algorithms. There are three major contributions: first, the data structure can be created quickly a...

In secure information flow analysis, the classic Denning restrictions allow a program’s termination to be affected by the values of its H variables, resulting in potential information leaks. In an effort to quantify such leaks, in this work we study a simple imperative language with random assignments. As a thought experiment, we propose a “stripping” operation on programs, which eliminates all...
