Biorefinerias: Estrategia de Parametrizacion del Modelo A-Unifac
ISBN: 9783659024580 / Hiszpański / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Los recursos convencionales, principalmente los combustibles fosiles son limitados y no amigables desde el punto de vista ambiental. Esto ha impulsado la busqueda de recursos energeticos sostenibles. La biomasa, a partir de la cual puede obtenerse combustibles y productos quimicos diversos en una biorefineria, cumple con tal premisa. Una biorefineria seria el equivalente a una refineria de petroleo en la que la materia prima no son los combustibles fosiles sino la biomasa. La transformacion de la biomasa en sus derivados implica el procesamiento de mezclas multicomponentes no-ideales,...

Gasoline Additives (Gasoline Oxygenates)
ISBN: 9783659160394 / Angielski / Miękka / 384 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The study of gasoline + alcohol and ethers mixtures using the methods of physical-chemical analysis is considered at the present time as a difficult goal as gasoline is an extremely complex mixture of hydrocarbons of varying composition. Ethers and alcohols are being blended with gasoline to increase octane number and to reduce air pollution problems associated with leaded gasoline.Ethers and alcohols used as gasoline additives (oxygenates) have excellent antiknock properties and are environmentally acceptable substances. The calculation of vapor-liquid equilibria of gasoline additives is...

Challenges to 2nd law of thermodynamics, surface tension and some mech
ISBN: 9783659213397 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Cohesion pressure in liquid due to inward intermolecular force on surface molecules, not surface tension, causes minimization of liquid surface. Surface tension isnt what causes horizontal wire sliding on two limbs of a U-shaped wire to be in equilibrium in any position. Incorrectness of current relations for pressure differences between inside and outside of a bubble and one related to a solid drop is proven. In surface evaporation liquid increases the potential energy of its molecules by taking heat while their kinetic energies remain unchanged. Gas temperature decreases due to surface...

On Phase-Transition Radiation of Water
ISBN: 9783659205149 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book presents the first study on the radiative relaxation mechanism of water between its different phases in order to explain an uncommon radiation phenomenon observed in the first-order phase-transition process of water. This kind of radiation is often referred to as phase-transition radiation, whose nature is different from the Planckian radiation because its strength can be even stronger than blackbody radiation at the same temperature. Changes of energetic behaviors of water molecules during phase transitions are linked to the direct emission of infrared radiation. The reported...

Modeling The Effects of Electromagnetic Field on Plasmodium Falciparum
ISBN: 9783659225284 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The study explores the potential effects of the remote application of cyclic magnetic field to the female anopheles mosquitoes that carry malaria parasites. The goal is to develop a theoretical basis that can guide the cyclic activation of the magnetic field to induce the inactivity of the malaria parasite without killing the mosquitoes. The model considers the hemozoin within the malaria parasite as a cluster of magnetic nanoparticels. The potential effects of the applied magnetic field are then considered within a thermodynamic frame framework. The induced heat generated is computed...

Thermal Analysis of Induction Cooktops
ISBN: 9783659223082 / Angielski / Miękka / 144 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Induction cooking is not a radically new invention; it has been widely used all around the world. With recent improvements in technology and the consequent reduction of component costs, Induction cooking equipment is now more affordable than ever. According to the U.S. Department of Energy, the efficiency of energy transfer for an induction hob is 84%, versus 38% for Gas stove and 68% for a smooth-top non-induction electrical unit, for an approximate 16% saving in energy for the same amount of heat transfer. This study reveals the thermal analysis and efficiency of an induction cooktop with...
