Solar Thermochemical Conversion of CO2 into C via SnO2/SnO Redox Cycle: A The...IJERA Editor
In this paper we report the computational thermodynamic modeling of the solar thermochemical SnO2/SnO
redox cycle for solid C production via CO2 splitting. In this redox cycle, the first step corresponds to the solar
thermal reduction of SnO2 into SnO and O2 in presence of inert atmosphere. The second step, which is a nonsolar
exothermic stage, is the reaction of SnO with CO2 to produce solid C together with SnO2 that is recycled
back to the first step. Commercially available HSC Chemistry software and databases were used for the
computational thermodynamic modeling of this process. The thermodynamic analysis was performed in two
sections: 1) equilibrium composition analysis, and 2) exergy analysis. Results obtained via the computational
thermodynamic modeling are presented in detail. The simulation results indicate that the solar thermochemical
SnO2/SnO redox cycle for solid C production via CO2 splitting can achieve the solar to fuel conversion
efficiency upto 12%.

Go Social or Die: Why Digital Competence Can't Be Ignoredjonnie jensen
Too many businesses are not embracing digital and social technologies. Stuck in the comfort of their existing processes and frightened by tabloid headlines they fear losing control. Ultimately though new technologies result in higher productivity and increased revenues. The choice about achieving digital competence in your business is no longer choice. Quite simply it is go social…or die.

Presentation by Laurian Unnevehr at the event, “2013 AAEA & CAES Joint Annual Meeting” which took place on August 4-6, 2013 in Washington, DC. It offers AAEA members, CAES members, and other applied economists a chance to interact and learn over the course of the three day meeting.
Carbon-cuprous oxide composite nanoparticles
were chemically deposited on surface of thin glass tubes of spent
energy saving lamps for solar heat collection. Carbon was
obtained from fly ash of heavy oil incomplete combustion in
electric power stations. Impurities in the carbon were removed by
leaching with mineral acids. The mineral free-carbon was then
wet ground to have a submicron size. After filtration, it was
reacted with concentrated sulfuric/fuming nitric acid mixture on
cold for 3-4 days. Potassium chlorate was then added drop wise on
hot conditions to a carbon slurry followed by filtration.
Nanocarbon sample was mixed with 5% by weight PVA to help
adhesion to the glass surface. Carbon so deposited was doped with
copper nitrate solution. After dryness, the carbon/copper nitrate
film was dipped in hydrazine hydrate to form cuprous oxide -
carbon composite, It was then roasted at 380-400 °C A heat
collector testing assembly was constructed of 5 glass coils
connected in series with a total surface area of 1250 cm2
. Heat
collection was estimated by water flowing in the glass coils that
are coated with the carbon/copper film,. Parameters affecting the
solar collection efficiency such as time of exposure and mass flow
rate of the water were studied. Results revealed that the prepared
glass coil has proven successful energy collector for solar heat.
Experimental Investigation on Adsorption Capacity of a Variety of Activated C...IJERA Editor
This study aims to develop a device with minimum heat and mass transfer limitations between adsorbent and
adsorbate, and subsequently to obtain practically applicable adsorption capacity data. Also, 5 kW adsorption
chillers (evaporators, condensers and adsorbers) are designed based on the experimental output data of the whole
tested pairs. A finned-tube heat exchanger was employed and installed at the center adsorber, and each employed
adsorbent was immobilized on its surfaces by using an adhesive agent. A variety of pairs: are activated carbon
powder (ACP)/R-134a, ACP/R-407c, ACP/R-507A, activated carbon granules (ACG)/R-507A, ACG /R-407c
and ACG /R-134a, were examined at different adsorption temperatures of 25, 30, 35 and 50°C. It was found that,
at the adsorption temperature of 25°C the maximum adsorption capacity was 0.8352 kg kg-1 for ACP/R-134a,
while at the adsorption temperature of 50°C the maximum adsorption capacity was 0.3207 kg kg-1 for ACP/R-
134a. Therefore, the ACP/R-134a pair is highly recommended to be employed as adsorption refrigeration
working pair because of its higher maximum adsorption capacity higher than the other examined pairs.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Neuro-symbolic is not enough, we need neuro-*semantic*
