The main objective of this research is stability determination of activated carbon adsorbent at fixed bed adsorption column for desulfurization of diesel fuel by mathematical modeling. This model is based on mass balances. Equations that are the outcome of mass balances are known as the second degree of partial differential equations, and they must be solved together simultaneously...

We present an experimental and theoretical study of the breakthrough performance of the flexible metal-organic framework Cu(bpy)2(BF4)2 (bpy = 4,4'-bipyridine), termed ELM-11. Pure CO2, He, CH4, and N2 gases, as well as binary gas mixtures of those species, were used to perform breakthrough experiments on ELM-11. ELM-11 exhibits a stepped breakthrough curve for CO2 not seen in rigid adsorbents....

In this work, the dynamical behavior of the US stock markets is characterized on the basis of the temporal variations of the Hurst exponent estimated with detrended fluctuation analysis (DFA) over moving windows for the historical Dow Jones (1928–2007) and the S&P-500 (1950–2007) daily indices. According to the results drawn: (i) the Hurst exponent displays an erratic dynamics with some episode...

The aim of this study was to evaluate the usefulness of serum (1,3)-beta-D-glucan (BDG) for earlier detection of breakthrough candidemia. We reviewed the medical records of patients with candidemia from January 2008 to March 2013. Serum BDG was measured by Wako turbidimetric assay. During the study period, a total of 147 cases of candidemia were identified, and 31 patients met the criteria for ...

Abstract A sets of sand column experiments were conducted to investigate the transport and deposition of colloids in water-saturated porous media, and the mechanism of the permeability reduced by transport and deposition of colloids are discussed. The research results show that the breakthrough curves of colloid transport in water-bearing media presented as three stages: “not-yet-breakthrough”,...

Seizures are one of the commonest neurological symptoms seen in children. Recurrent seizures could ensue from epilepsy, febrile seizures, provoked seizures, drug inefficacy or with, or due to unknown or systemic illnesses [1]. A breakthrough seizure is an epileptic seizure that occurs, despite the use of anticonvulsants that have otherwise successfully prevented seizures in the patient. Breakth...

background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

Antibiotics, such as sulfadiazine, reach agricultural soils directly through manure of grazing livestock or indirectly through the spreading of manure or sewage sludge on the field. Knowledge about the fate of antibiotics in soils is crucial for assessing the environmental risk of these compounds, including possible transport to the groundwater. Transport of (14)C-labelled sulfadiazine was inve...

Virological breakthrough is a clinical manifestation in patients infected with chronic hepatitis B (CHB), who undergo treatment with nucleoside/nucleotide analogs (NUCs). The current understanding of the underlying mechanism of virological breakthrough is limited. Ultra‑deep pyrosequencing (UDPS) is a novel and powerful tool used to investigate minor viral variants and viral evolution. The pres...
