Linear and nonlinear forms of two-parameter isotherm models are generally implemented to describe characterize an adsorption process. Throughout the previous studies associated with adsorption process, less attention has been paid to comparison of these two methods. The current study was developed to investigate mathematical and statistical properties of these two methods and compare different statistical criteria to specify the best linear and nonlinear curves, fitted to experimental data and estimate isotherm parameters. Toward these aims, the data obtained from an empirical study on nitrate adsorption onto oyster shell coated with nanoparticle zero-valent iron (OS-nZVI) were applied.................

In real-time transmission of multimedia information Ad Hoc faces challenges for the low bandwidth for transmission from source to destination and requires a considerable effort. So we proposed a queuing network model which is based on routing of Ad Hoc networks and analyze the delivery of multimedia packets which has low end-to-end delay and less bandwidth overhead between mobile nodes and which ensures high throughput. We also analyzed the queuing delay in regard of node behaviour of routing and MAC protocols. Here we simulate the parameters of Quality of Service i.e. end-to-end delay and expected hop count using Matlab..........

In this study, the lowering pattern in Mandarin tone production is analyzed, and it is found that downstep exists for high (H) tones. They always drop to a lower scale compared to the forgoing ones. The degree of the first downstep is always larger than the following ones, but there are no differences in the degrees of downsteps for the later HL sequences. The speaker does not only raise the initial H tone when there are more downsteps, but also depress the final H tone. As for the L tones, due to the effect of final lowering, the lowering degree of the last downstep is always larger than the preceding ones. The utterance final L tones are not affected by the number of downsteps. Keywords - Tone, pitch, downstep @article{key:article,

This study examined the Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) & Chemical Oxygen Demand (COD) in summer, rainy& winter season to assess the water quality and sessional variations of Solmari River, Bangladesh. The highest DO value was observed in rainy season than winter or summer season. But the BOD and COD was high during winter and rainy season. This high level of BOD and COD value in summer season indicates the presence of a large number of microorganism's i.e. high level of pollution.

Thermal plasma technique is becoming prominent in the treatment of variety of waste ranging from municipal solid waste, incinerator residue, hospital waste, electronics waste and industrial sludge. Application of the new treatment technology to petroleum sludge requires information on the nature and characteristics of the sludge that will be use to optimize the treatment system. In this investigation, petroleum sludge obtained from Petronas Melaka was characterized for its physical and chemical features. Proximate and ultimate analysis as well as determination of elemental composition were carried out. The sludge was found to contain high moisture (78.91%), low ash (5.06%), low volatiles (5.52%) and high fixed carbon (10.51%). The sludge has a TOC of 54.48% and HHV of 23.599MJ/kg...........

Martin Heidegger stands out as one of the greatest philosophers in the contemporary period. His philosophy centers on Being. His contribution to philosophy is to recover the real meaning of Being that other philosophers had forgotten. For him, Being manifests itself anew at different times. He approaches this problem of Being in three stages, the first stage is Dasein analysis, the second is art and truth as a path to Being; the final stage is Being as a process that is expressed as ereignis (eyes of the mind) and Gelassenheit (surrender). Science and technology falls with the second stage of Heidegger's view on Being. Heidegger is not against science and technology but the abuse...........

This study investigates the inflation-hedging characteristics of real estate stocks in Vietnam. Empirical findings show that securitized real estates can provide a partial hedge against both ex post and ex ante inflation, but no statistical relation between securitized real estates returns and surprises in inflation is found.

Improved passive safety and weight reduction are both required for components of new car generation. Thus, advanced high strength steels, such as dual phase steels are increasingly used in car-body production. In each sheet metal forming process, the steels exhibit springback effect, which is governed by strain recovery of material after load removal. High strength steels exhibit more distinct springback effect than steels used for deep drawing. This is mainly due to their higher values of Yield strength. Springback is related to many parameters like forming conditions, tool geometry and material properties such as sheet thickness, yield stress, work hardening, strain rate sensitivity and elasticity modulus. [1-3] In this contribution, effect of blank holder force (BHF) value and value of friction coefficient on springback of stamped part is evaluated.

This paper represents some new experimental results about thermal, mechanical and magnetic properties in NiMnGaFe ferromagnetic shape memory alloy. Ni54Mn18Ga20Fe8 polycrystalline shape memory alloy was fabricated by an arc melting device providing inert argon gas atmosphere. Martensitic transformation (MT) temperatures of Ni54Mn18Ga20Fe8 alloy were determined by DSC and the crystal structure of alloy was investigated by XRD. Shape memory effect of alloy was determined by TMA and after the necessary calculations are made, the results are found as the residual strain r = 3, shape memory effect SME = 2.6 and the recovery rate = 86.6%. The magnetic properties were determined using Mossbauer spectroscopy. The magnetic properties were determined using Mossbauer spectra. The results demonstrated that the presence of two phases coexist which are gamma phase and martensitic phase. Keywords - Martensitic Phase Transformation, Mossbauer, SEM, Shape Memory Alloy, XRD. @article{key:article,

The color decrease aesthetical quality of drinking water and consumer's tendency for using this water. Furthermore, colored water is unsuitable for industrials usage. Color producing material may react with chlorine compounds and creates carcinogen disinfection by products (DBPs). The aim of this study was to investigate Acid Red 18dye removal from aqueous solution by combined conventional coagulation and nanoparticle zero valent iron (nZVI) process. The experiments were conducted in jar test device and efficiency removal was evaluated by changing alum concentration, nZVI dosage, and pH. On the basis of the results, removal efficiency for integrated process was higher than only conventional coagulation. The color removal efficiency for integrated process and coagulation were 93 and 47 percent, respectively. Integrated process can be used effectively for color removal from water in regions with color problems. More studies are needed to investigate other aspects of this process. Keywords - Coagulation, nZVI, Acid Red 18. @article{key:article,
