Diffusion coefficients in ion-exchange membranes tested in this study were found to be dependent on concentration of the upstream solution, with an exception of Ca2+ in anionexchange membranes and NO3- in cation-exchange membranes. The role of osmosis in water transport in ED-M process was found negligible.

The essential oil is mostly depends on the temperature. The temperature will influence the final product of the extraction process. The existing steam distillation processes are giving less intention on this issue. This work implemented the robust self-tuning fuzzy PID (STFPID) controller to monitor the steam temperature in the hydro-diffusion essential oil extraction system. The hydro-diffusion system is built to overcome some weakness of existing systems. The effectiveness of the STFPID using

Cyclic Temporal Network Density and its impact on Information Diffusion for Delay Tolerant Networks

We adopt temporal graph model to explore the dynamic temporal properties of three mobility datasets in DTN (Delay Tolerant Network), collected from different sources, including one university campus WLAN and two conferences WLANs. With this model, we observe that the temporal network density of DTN changes with time and approximate varies periodically. Then we study the impact of this phenomenon on information diffusion. Our studies and findings can be used for establishing more realistic

Computational Model Of Plasma-Organic-Polymer-Film-Coated QCR Sensor For Analysing Its Dynamic Response

This paper proposes a computational model of the mass-sensitive chemical sensor with plasma-organic-polymerfilm-coated quartz crystal resonators for use in sensor signal processing to develop a high-performance electronic nose system. Assuming one-dimensional Fickian diffusion of sample gas molecules, diffusion equation is applied to sample gas molecules in the sensor film bulk to describe the responses of the chemical sensor to the sample gas. Green’s function is introduced to solve the

COVID-19 Health Communication Networks on Twitter: Identifying Sources, Disseminators, and Brokers

. COVID-19 is the first pandemic of its kind in the age of social media. The amount and nature of information available to the public has changed significantly and is constantly evolving. Unfortunately, a crucial but surprisingly understudied phenomenon is the diffusion of health information on social media (Zhou et al., 2018; Aramburu et al., 2020). Twitter, a microblogging service, has become one of the most important sources of realtime news updates, with more than 64 million users in the U.S

The doping process is reversible, and the experimental results are interpreted in terms of adsorption and diffusion of the gas in the polymer, charge transfer, and transport of the injected carriers in the polymer chain. These experimental results and previous studies on other polymers and oxidizing gases demonstrate the potentiality of such materials to be used as sensitive part of gas sensors.

Assessment and Treatment of Identity Pathology During Adolescence

“identity” has been integrated as a core diagnostic criterion for personality disorders.One of the most central tasks of normal adolescent development is the consolidation of identity. Crises in the development of identity usually resolve into a normal and consolidated identity with flexible and adaptive functioning. By contrast, identity diffusion is viewed as a lack of integration of the concept of the self and significant others; it is also seen as the basis for subsequent personality pathology

Do Men Discuss Birth Control? A Social Network Analysis in Bangladesh

population control in broader social structures is also gaining momentum, as recent studies on diffusion have shown that fertility choices often are made within a social network (Behrman et al., 2002; Kincaid, 2000; Montgomery and Casterline, 1993; Rutenberg and Watkins, 1997; Perkins et al., 2015). Even so, few studies have focused on the role of men enmeshed within social and institutional structures. This is especially wanting in the fertility studies in the South Asian context, which is characterised

Networks and Religion: Ties that Bind, Loose, Build Up, and Tear Down

That social networks play a central role in religious life is well accepted by most social scientists. We are reasonably confident, for instance, that they are crucial for the recruitment and retention of members, the diffusion of religious ideas and practices, motivating individuals to volunteer and become politically active, the health and well-being of people of faith, and conflict, radicalization, and (sometimes) violence. However, in conference presentations, journal articles, and books

Structural Cohesion: Visualization and Heuristics for Fast Computation

The structural cohesion model is a powerful theoretical conception of cohesion in social groups, but its diffusion in empirical literature has been hampered by operationalization and computational problems. In this paper, we start from the classic definition of structural cohesion as the minimum number of actors who need to be removed in a network in order to disconnect it, and extend it by using average node connectivity as a finer grained measure of cohesion. We present useful heuristics for

antibiotic susceptibility test was done using the diffusion method. Biofilm formation was evaluated with microplate method using TTC. Bacteremia caused by Proteus spp. was found in 97 patients, mainly secondary to urinary tract infection. Most of the strains were susceptible to piperacillin with tazobactam (95.9%) and amikacin (86.7%). Elderly patients have a higher risk of mortality after BSIs caused by Proteus spp. A detailed analysis was made for randomly chosen 26 strains isolated from 11 patients

Emergence of High-level Gentamicin Resistance among Enterococci Clinical Isolates from Burn Patients in South-west of Iran: Vancomycin Still Working

Enterococcus faecalis and Enterococcus faecium are among the main agents associated with nosocomial infections with high mortality in immunocompromised patients. Antibiotic resistance, especially against gentamicin and vancomycin among Enterococci, is a risk factor that could increase the morbidity and mortality rate. 179 Enterococci isolates from burn patients were included in this study. Antibiotic susceptibility testing was done using the disk diffusion test and minimum inhibitory

A new miniscrew, The Sydney Mini Screw (SMS), with a hollow chamber and lateral port holes, has been developed to allow the diffusion of an injectable bone graft substitute (iBGS) into cancellous bone. The aim of this study was to analyse the optimum iBGS application with ideal chemo-mechanical properties to be used in
