Pemanfaatan Running Text Sebagai Alat Bantu Informasi Minggu Perkuliahan Di Biro Administrasi Akademik dan Kemahasiswaan (BAAK) Politeknik Negeri Bengkalis
No full textBengkalis State Polytechnic is the only state polytechnic in Riau province. Within the organizational structure of Polbeng there is a sub-section of the Academic and Student Administration Bureau (BAAK) which takes care of academic and student affairs. BAAK Polbeng is an information center related to academics and students, but in its own office it does not have information media to deliver announcements related to the week of lectures which is very important information for students and lecturers to count the number of meetings that have been held. However, with this problem the author provides a solution by making a running text that is installed in front of the BAAK Polbeng office in the GKT3 building. So that with this running text, information from BAAK is easily conveyed to students and lecturers
Effect of different aqueous solutions of pure salts and salt mixtures in reverse electrodialysis systems for closed-loop applications
No full textReverse Electrodialysis (RED) in a closed-loop arrangement is a viable way to convert low-grade heat into
electric power. The present work experimentally investigates the use of pure salt- and equimolar two salts-water
solutions as feeds in a lab-scale RED unit. RED performances were analysed in terms of Open Circuit Voltage
(OCV), stack resistance and corrected power density. The pure salts and the mixtures employed were chosen via
a computational analysis. Effect of feed solution velocity and concentration was investigated. Results concerning
the pure salt-water experiments show that NH4Cl is the most performing salt in the concentration range probed,
while higher power density values are expected with the use of LiCl at larger concentrations. As regards the salt
binary mixtures, in some cases, the measured stack electrical resistance was found lower than both the two
values measured for the corresponding pure salts, thus resulting into higher power density values for the mixtures.
This surprising experimental evidence suggests that it is possible to increase the power produced by a
conventional RED unit by adding an equivalent molar quantity of another suitable salt. Finally, among the
mixtures tested, the NH4Cl-LiCl mixture appears as the most promising, thanks to the combination of the favorable
properties of these two salts
Reverse electrodialysis heat engine for sustainable power production
No full textReverse Electrodialysis Heat Engine (REDHE) is a promising technology to convert waste heat at temperatures lower than 100. °C into electric power. In the present work an overview of the possible regeneration methods is presented and the technological challenges for the development of the RED Heat Engine (REDHE) are identified. The potential of this power production cycle was investigated through a simplified mathematical model. In the first part of the work, several salts were singularly modelled as possible solutes in aqueous solutions feeding the RED unit and the corresponding optimal conditions were recognized via an optimization study. In the second part, three different RED Heat Engine scenarios were studied. Results show that power densities much higher than those relevant to NaCl-water solutions can be obtained by using different salts, especially those based on lithium ion (i.e. LiBr and LiCl). Results on the closed loop show efficiencies up to about 15% corresponding to an exergetic efficiency of about 85%, thus suggesting that the RED Heat Engine could potentially be a promising technology, with applications mainly in the industry where low-grade heat that has no alternative use can be converted into electricity
Comparative morphometric analysis of nuclear area and shape in peripheral T-zone lymphomas and in paracortical areas of normal and reactive lymph nodes
No full textThe areas and shapes of cell nuclei were morphometrically analyzed in peripheral T-zone lymphomas, which have a characteristic nuclear pleomorphism, as well as in paracortical areas of normal and reactive lymph nodes; the aim of the study was to compare the neoplastic and nonneoplastic lymphoid cell populations. Although the means and standard deviations (SDs) of nuclear area and shape features differed significantly between the T-zone lymphomas, reactive nodes and normal nodes, there was considerable overlap between the lymphomas and the reactive lymph nodes in all of the features investigated. Therefore, the composition of populations of nuclei was studied. In lymphomas, the frequencies of regular and irregular nuclei were about the same in all nuclear area classes, whereas increasingly larger nuclei had an increasingly regular shape in reactive lymph nodes. An attempt to classify the cells, divided into those with small nuclei (<25 sq μm) and those with large nuclei (>25 sq μm), on the basis of their morphometric shape features showed the usefulness of form factors in the class of nuclei with a large area. The results show that, while means and SDs of nuclear area and shape are not very accurate descriptors of the differences between the T-zone lymphomas and nonneoplastic lymph nodes, analysis of the percentage of regularly shaped nuclei in a certain nuclear area class can describe the differences much more accurately. The compositional differences in nuclear shape are in agreement with subjective impressions and can objectively support the pathologist's qualitative impression of pleomorphism in malignant T-zone lymphomas
A novel Reverse Electrodialysis application to generate power from low-grade heat
No full textA novel idea for the conversion of low-temperature heat into electricity is based on the generation
of electricity from salinity gradients using a Reverse Electrodialysis (RED) device in a closed-loop
system. In this concept a limited amount of artificial saline solutions can be used as the working
fluids in a closed-loop. The solutions exiting from the RED unit are then regenerated, in order to
restore the original salinity gradient, by means of a separation step, which uses low-temperature
heat (40-100°C) as its energy source. A theoretical analysis of potentials of this technology is illustrated in the present work
Reverse Electrodialysis with seawater and concentrated brine: a comprehensive process modelling
No full textModelling the Reverse ElectroDialysis process with seawater and concentrated brines
No full textTechnologies for the exploitation of renewable energies have been dramatically increasing in number, complexity and type of source adopted. Among the others, the use of saline gradient power is one of the latest emerging possibilities, related to the use of the osmotic/chemical potential energy of concentrated saline solutions. Nowadays, the fate of this renewable energy source is intrinsically linked to the development of the pressure retarded osmosis and reverse electrodialysis technologies. In the latter, the different concentrations of two saline solutions is used as a driving force for the direct production of electricity within a stack very similar to the conventional electrodialysis ones. In the present work, carried out in the EU-FP7 funded REAPower project, a multi-scale mathematical model for the Salinity Gradient Power Reverse Electrodialysis (SGP-RE) process with seawater and concentrated brines has been developed. The model is based on mass balance and constitutive equations collected
from relevant scientific literature for the simulation of the process under extreme conditions of solutions concentration. A multi-scale structure allows the simulation of the single cell pair and the entire SGP-RE stack. The first can be seen as the elementary repeating unit constituted by cationic and anionic membrane and the relevant two channels where dilute and concentrate streams flow. The reverse electro-dialysis stack is constituted by a number of cell pairs, the electrode compartments and the feed streams distribution system. The model has been implemented using gPROMS , a powerful dynamic modelling process simulator. Experimental information, collected from the FUJIFILM laboratories in Tilburg (the Netherlands), has been used to perform the tuning of model formulation and eventually to validate model predictions under different operating conditions. Finally, the model has been
used to simulate different possible scenarios and perform a preliminary analysis of the influence of some process operating conditions on the final stack performance
