The occurrence of arsenic in water is a global problem for public health. Several removal technologies have been developed from water, and adsorption onto iron oxy-hydroxides the most widely used technique. Granular ferric hydroxide (GFH) has mainly As(V) removal, but it disadvantage that can create with residual concentration water. Moreover, graphene oxide (GO), which contains large amount re...

Given two graphs G and H and a function f ⊂ V (G) × V (H), Hedetniemi [9] defined the function graph GfH by V (GfH) = V (G)∪ V (H) and E(GfH) = E(G) ∪ E(H) ∪ {uv|v = f(u)}. Whenever G ∼= H, the function graph was called a functigraph by Chen, Ferrero, Gera and Yi [7]. A function graph is a generalization of the α-permutation graph introduced by Chartrand and Harary [5]. The independence number ...

Ball milling and ultra-sonication size reduction procedures were applied to granular ferric hydroxide (GFH) obtain two micro-sized adsorbents. These adsorbents GFH investigated improve the removal of phosphates from water. The procedures, using method, allowed a 0.5–2 mm 0.1–2 µm total disaggregation structure. Using an method yielded final 1.9–50.3 with partial disaggregation. Langmuir model c...

The Generalized Frequency Hopping (GFH) OFDMA system developed in this paper permeates FH bene ts to multicarrier CDMA transmissions through unknown frequencyselective multipath channels. No single user su ers from consistent fading e ects and multiuser interference is eliminated by design. Constellation-irrespective channel identi ability is guaranteed, and a host of blind channel estimation a...

the aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (gfh). the effect of factors such as initial concentration of nitrate, ph, contact time, and adsorbent mass were determined. the study was done in laboratory–scale in which synthetic nitrate solutions in a batch reactor were placed in contact with the adsorbent to model adsorption kinetics. it was found ...

The methodological features of determining the characteristics wave groups sea surface waves based on function smoothed instantaneous through energy (SIWEH) are analyzed. analysis is carried out by numerical simulation an analytical model group structure waves. It shown that when grouping investigated using SIWEH function, it advisable to calculate Groupiness Factors Height (GFH) in two stages....

Helicobacter pylori, is an invariably commensal resident of the gut microbiome associated with gastric ulcer in adults. In addition, these patients also suffered from a low grade inflammation that activates the immune system and thus increased shunting of energy to host defense mechanisms. To assess whether a H. pylori infection could affect growth in early life, we determined the expression le...
