Abstract:
The adsorption of methyl orange (MO) from aqueous solutions onto a KOH-activated polypyrrole-based adsorbent (PACK) was investigated using batch and fixed-bed column techniques. The structural, thermal, and morphological properties of the PACK, analyzed by various methods, support its applicability as an adsorbent. An adsorption kinetic study revealed a preferably pseudo-second-order (R2 = 0.9996) and rate-limiting step controlled by both film and intra-particle diffusions. The thermodynamic adsorption tests resulted in negative ΔG°, ΔH°, and ΔS° values, which decreased as the temperature and

Diffusion models are one of the main methods for studying economic objects and processes. This is why it is so important to develop a diffusion model. The authors propose e

We develop a method for estimating equilibrium moisture content (EMC) and fuel moisture response time, using data collected for Eucalyptus twig litter. The method is based on the governing differential equation for the diffusion of water vapour from the fuel, and on a semi-physical formulation for EMC (Nelson 1984), based on the change in Gibbs free energy, which estimates the EMC as a function of fuel temperature and humidity. We then test the model on data collected in Western Australian mallee shrubland and in Tasmanian buttongrass moorland. This method is more generally applicable than tho

Aiming at the phenomenon, the paper concludes that both the drift parameter and the diffusion parameter depend on stress variables based on the invariance principle of failure mechanism and Nelson assumption.

Industrial compost piles contain large volumes of bulk organic materials. Normally, there are two main heat generation processes—oxidation of cellulosic materials and biological activity within the compost pile. Biological heating occurs at a lower temperature range, but it may `kick-start' the oxidation reaction. Nevertheless, biological heating is desirable and is a key component in composting operations. However, there are cases when the temperature within the compost piles increases beyond the ignition temperature of cellulosic materials which can result in spontaneous ignition. This inves

Among the famous formulations of quantum mechanics, the stochastic picture developed since the middle of the last century remains one of the less known ones.

The mathematical foundations of this approach were laid by Edward Nelson in 1966. It allows a different perspective on quantum phenomena without necessarily using the w

Abstract:
It is now well recognized that education expedites the process of growth in an economy. In agriculture, leaving aside the external effects, it affects productivity in two quite distinct ways known as the allocative effect and the worker effect (Welch, 1970). The former centres on beller allocation decisions including adoption and diffusion of new technology whereas the latter relates to a more efficient use of given inputs, i.e. the technical efficiency aspect of production. While the allocative effect is inherently predicated on disequilibrium (created, for example, by a change in technology)

This paper presents the methodology for the preparation of hydrochar obtained from waste materials of natural origin and investigates its applicability for removing mercury ions from aqueous systems. The sorption properties of the obtained hydrochar were investigated in a batch and in a flow-through column system. The hydrochar material was obtained from apple pomace, which was hydrothermally carbonized in 230 °C for 5 h in a hydrothermal reactor. The hydrochar formed in the process was thermally activated with an inert gas flow—CO2. Obtained materials were characterised with XRD, FTIR-ATR, SE

Radioimmunoassay and semiquantitative video analysis of immunofluorescence on frozen sections showed that one apical and three basolateral glycoproteins, defined by monoclonal antibodies and binding of beta-2-microglobulin, were incompletely extracted with 0.5% Triton X-100 in a buffer that preserves the cortical cytoskeleton (Fey, E.

Sodium-ion batteries (SIBs) has been received growing attention in the electrical energy storage fields due to their low cost and earth-abundant sodium.

Despite the chemical similarities between sodium and lithium as alkali elements, the larger Na ion than Li ions (ionic radii of 0.98 Å and 0.68 Å, respectively) is limited to insertion into host materials and results in different phase transition behavior.

1548 Background: Lung cancer screening continues to be an area of great opportunity in public health, especially in developing countries. In Mexico, about 10,000 new cases of lung cancer are detected annually, of which less than 5% are diagnosed in early stages. There are no national programs for timely detection of lung cancer in our country, so it is essential to seek accessible measures to prioritize resources for high-risk people. Methods: We developed a web app that consisted of a short survey to stratify patients according to their risk of lung cancer (https://cuccuanl.com/tamiz_pulmon/)

AbstractThe performance of crab shell chitosan (600 µm) as prospective adsorbent for phenol removal was studied in dynamics mode. The chitosan adsorbent had specific surface area of 191 m2/g and showed the surface characteristics linked to amine/amide groups. The effects of operating conditions on phenol adsorption at different concentrations (100 and 200 mg/L), flow rates (2.17 and 2.90 mL/min) and bed heights (1.75 and 3.5 cm) were evaluated. Results showed that the maximum phenol adsorption capacity by the crab shell chitosan was recorded at 190 mg/g. Thomas, Yoon–Nelson and Adam–Bohart mod

In this paper, Schrödinger analyses the idea of time reversal of a diffusion process. Schrödinger’s paper acted as a prominent source of inspiration for the works of Bernstein on reciprocal processes and of Kolmogorov on time reversal properties of Markov processes and detailed balance. The ideas outlined by Schrödinger also inspired the development of probabilistic interpretations of quantum mechanics by Fényes, Nelson and others as well as the notion of “Euclidean Quantum Mecha

Introduction Many anthropologists and other academics have attempted to argue that the spread of technology is a global homogenising force, socialising the remaining indigenous groups across the planet into an indistinct Western "monoculture" focussed on consumption, where they are rapidly losing their cultural distinctiveness. In many cases, these intellectuals -– people such as Jerry Mander -- often blame the diffusion of television (particularly through new innovations that are allowing it to penetrate further into rural areas, such as satellite and cable) as a key force in the effort to "a
