To characterize the drying process in the Gol-E-Gohar pelletizing plant ball mill the material veiling profile (material showering) was studied by physical modeling and DEM. To simulate the trajectory of particles in the dryer in a reasonable period of time the GPU parallel processing was implemented in the DEM codes. After calibration of DEM parameters by using the model dryer, various flight designs were then employed in the simulation to find an appropriate veiling profile. It was found that by ...

Proton exchange membranes (PEMs) are the most frequently used separators in microbial fuel cells (MFCs). The role of proton transportation in MFC performance makes PEMs one of the most important components in the cell. The effect of PEMs in MFC performance is commonly determined according to generated power density and coulombic efficiency. Nafion is the commonly used membrane in MFCs, but there are still a number of problems associated with the use of Nafion including oxygen transfer rate, cation ...

In this work, the optical applications of g-C3N4 modified with Hg2+ as a fluorescence sensor for quantification of two toxic anions (CN− and Cr2O72−) were studied. The prepared nanostructures were characterized with XRD, FTIR, TEM and luminescence techniques. TEM image revealed that the size of nanostructures is smaller than the 60 nm. Investigation of fluorescence emission showed that the modified g-C3N4 has two distinct emission spectra centered at 368 and 450 nm. The ability and feasibility use ...

Studies indicated that imbalance of proinflammatory and anti-inflammatory cytokines may contribute to development of type 2 diabetes mellitus (T2DM). We hypothesized that sitagliptin and VitD3 may exert more anti-inflammatory effects on the regulation of cytokine balance in T2DM. Nonnephropathic and nephropathic T2DM patients were divided into the subgroups, based on treatments. The effect of 8 months sitagliptin, alone or together with 2 months of VitD3, on serum IFN-γ, IL-4, IL-17, IL-6, IL-21, ...

Zero-valent metals such as Al0, Zn0, Ti0, and Fe0 with well explored catalytic activity have gained wide spread applications in the remediation proposes. Due to extremely high surface to volume ratio, nanoscale zero-valent metals showed increased catalytic potential and introduced as promising catalysts. Among zero-valent metal nanoparticles, zero-valent iron nanoparticles (ZVINPs) are one of the most employed nanostructures in remediation studies. These particles are effective Fenton-like catalysts ...

In this research, the effects of Selective Laser Melting (SLM) process parameters comprising laser power, scan speed, hatch space and scan pattern angle on the formation of porosity and subsequently density have been analysed. To improve the mechanical properties, post-processes (heat treatment) must be performed. Therefore, heat treatment was added to the design of experiment to analyse the effect of this process coupling with SLM process parameters on the value of density. A comprehensive design ...

FeOOH nanoparticles are commonly synthesized at very high temperature and pressure that makes the process energy consuming and non-economic. Recently, novel approaches were developed for the fabrication of these particles at room temperature. But, the main problem with these methods is that the prepared structures are aggregates of ultra-small nanoparticles where no intact separate nanoparticles are formed. In this study, for the first time, secretory compounds from Chlorella vulgaris cells were ...

In this paper, we propose a model to predict the average surface roughness (Sa) and analyse the effect of related process parameters on laser powder bed fusion (LPBF) selective laser melting (SLM) of Ti-6Al-4 V. The additive manufacturing (AM) process has various independent parameters that affect the quality of the produced parts and is complex to analyse. Although the process parameters can be selected separately in LPBF, they do however affect each other. Therefore, large adjustments of process parameters ...

Objective: The genes Bcl-2 and Bax play important roles in apoptosis. Many studies have shown that formalin has a strong deleterious effect on male fertility and can induce apoptosis. L-carnitine has been reported to potentially reverse the negative effects of formalin, leading to improved spermatogenesis. In this study, we examined the levels of expression of Bcl-2 and Bax in mice treated with formalin and L-carnitine.Methods: Thirty adult BALB/c mice were categorized into three groups. The mice ...

We investigate the stochasticity in temperature fluctuations in the cosmic microwave background (CMB) radiation data from the Wilkinson Microwave Anisotropy Probe. We show that the angular fluctuation of the temperature is a Markov process with a Markov angular scale, ΘMarkov = 1.01−0.07+0.09. We characterize the complexity of the CMB fluctuations by means of a Fokker–Planck or Langevin equation and measure the associated Kramers–Moyal coefficients for the fluctuating temperature field and its increment, . ...

N-glycosylation is a process during which a glycan moiety attaches to the asparagine residue in the N-glycosylation consensus sequence (Asn-Xxx-Ser/Thr), where Xxx can be any amino acid except proline. Introduction of a new N-glycosylation site into a protein backbone leads to its hyper-glycosylation, and may improve the protein properties such as solubility, folding, stability, and secretion. Glyco-engineering is an approach to facilitate the hyper-glycosylation of recombinant proteins by application ...

Partially shaded (PS) photovoltaic (PV) arrays have multiple peaks at their P-V characteristic. Although conventional maximum power point tracking (MPPT) algorithms are successful when PV arrays are under uniform irradiance conditions (UICs), their tracking speeds are low and may fail to track global maximum power point (GMPP) for PS arrays. Several MPPT algorithms have been proposed for PS arrays. Most of them require numerous samplings which decreases MPPT speed and increases energy loss. The proposed ...
