The cold battery is a heat exchanger between two fluids, air (secondary fluid) and iced water (primary fluid).The cold battery is composed of two heat exchangers in series, one of which is made up of flat-plate in galvanized steel serving as a reservoir for the iced water and the other one a copper shelland-tube exchanger with aluminum cooling blades. The two heat exchangers a connected pipe of the same diameter. These pipes will permit the transit of the iced water coming from the flat-plate exchanger by gravitation towards the tubes of the second exchanger. These two heat exchangers are incorporated …


Adsorption Of Co2 Molecule On The (Mgo)9 And (Cao)9 Nanoclusters; A Theoretical Study, Innovative Research Publications Irp India, Fathi Hassan Bawa Apr 2015

Adsorption Of Co2 Molecule On The (Mgo)9 And (Cao)9 Nanoclusters; A Theoretical Study, Innovative Research Publications Irp India, Fathi Hassan Bawa

Binding configurations of CO2 on (MgO)9 and (CaO)9 cluster models are investigated by means of density functional theory model calculations. The results show that CO2 adsorbs as monodentate on MgO and CaO terrace site leads to formation of surface carbonates CO3 2- . Marginal differences in the binding stabilities between the CO2 molecule and surface O2- site were found to be significantly similar. The estimated adsorption energies are 1.47 eV and 1.52 eV at the (MgO)9 and (CaO)9 clusters, respectively. The similarity in binding energies is discussed in terms of cluster electropositivity. Adsorbed CO2, to (MgO)9 surface vibration frequencies are …


Effect Of Eva Content Upon The Dielectric Properties In Ldpe-Eva Films, Innovative Research Publications Irp India, Hojjat, Amrollahi, Mahmood, Borhani Feb 2015

Effect Of Eva Content Upon The Dielectric Properties In Ldpe-Eva Films, Innovative Research Publications Irp India, Hojjat, Amrollahi, Mahmood, Borhani

Innovative Research Publications IRP India

Low density polyethylene (LDPE) blends with different percentages of ethylene vinyl acetate polymer membranes were prepared by a hot press casting method. The effects of EVA content on the electrical properties of LDPE were studied. The results on the electrical properties revealed that the surface resistance, volume resistivity, and breakdown voltage of the LDPE decrease with EVA content and reach a minimum at a 30 wt% of EVA. Dielectric constant and dielectric loss factor were increased with increasing EVA content up to 30 wt% of EVA. It can be deduced that the electrical properties of LDPE are improved by blending …


Neutron Generation From 10mev Electron Beam To Produce Mo99, Innovative Research Publications Irp India, Borhani Zarandi, Mahmood, Tabbakh, Farshid, Amrollahi Bioki, Hojjat Jan 2015

In this paper MCNP4C code has been used to simulate of the photonuclear interaction induced by 10MeV electron beam is an approach for generating the high intensity neutrons. Since the results are depended on the target material, the calculations are performed for the targets made of high z elements of Pb, Ta and W in a simple geometry.


Improvement Of Soil Physical And Chemical Properties With Municipal Solid Waste Compost Application In Soya Bean (Glycine Max), Mung (Vignaradiate), Lentil (Lens Culinaris) Seeds., Innovative Research Publications Irp India, Nisha Gupta, Manisha. Agrawal. Dec 2014

Innovative Research Publications IRP India

The present works were carried out to determine the impact of different municipal solid waste compost (mswc) soil extracts (Tap water, 5%, 10%, 15%, 20%, 25%, 30% and distilled water (control) obtained from mswc (degraded soil) and different mixing ratio of mswc and distilled water on the percentage of relative seed germination (RSG%), vigor index, root length, shoot length of soya bean (Glycine max). Mung (Vigna radiate,), Lentil (Lens culinaris) were studying by bioassay method. Seeds were sown in plastic pots as randomized completely block design with different concentration of soil extract Tap water, 5%, 10%, 15%, 20%, 25%, 30% …
