Interacting Particles Confined in Harmonic Oscillator Potentials
ISBN: 9783659767685 / Angielski / Miękka / 2015 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The first part of the book deals with the mathematical formulation of the solutions of Hartree-Fock equations of electrons confined in multiple centered harmonic oscillator potentials with anharmonic terms present. The interaction among electrons is taken as realistic Coloumb interaction. Confinement at four or more centers can be handled with the present algorithm. The trap geometries can be completely anisotropic. Roothaan procedure is used to convert the integro-differential Hartree-Fock equations to matrix algebra equations. Anharmonicities are expressed as polynomials of position...

Design, Development of Nitrendipin Self-Microemulsifying Drug Delivery
ISBN: 9786207448104 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Self-microemulsifying drug delivery system (SMEDDS) of Nitrendipine was aimed at overcoming the problems of poor solubility and bioavailability. The formulation strategy included selection of oil phase based on saturated solubility studies and surfactant and co-surfactant screening on the basis of their emulsification ability. Ternary phase diagrams were constructed to identify the self-emulsifying region. Ethyl oleate as oil, Cremophore RH40 as surfactant and PEG 400 as co-surfactant were concluded to be optimized components. The prepared SMEDDS was characterized through its droplet size,...

Diclofenac Potassium Tablet for Colon Targeting: Formulation
ISBN: 9786206181217 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The present study was to formulate tablet of Diclofenac potassium using the hydrophilic polymer hydroxy propyl methyl cellulose (HPMC), Hydroxypropyl Cellulose (HPC), Ethyl Cellulose(N22), Cross Povidone and Sodium Starch Glycolate as a superdisintegrants and Instacoat EN super II as a enteric coat to the colone specific tablet. A 33 randomized full factorial design, 3 level and 3 factors were used. The concentration of Hydroxy propyl cellulose (X1), concentration of HPMC K4M (X2) and concentration of Ethyl cellulose (X3) were selected as independent variables. The percentage drug release at...

Tribological Investigation & Development of Brass Composite Bearing
ISBN: 9786206946847 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. It is necessary to find the better combination of metal matrix solid lubricant that acts as solid lubricant for different application. With mixing the brass with different filler material such as MoS2. Graphite flakes and sub- micro particle of MoS2 and Brass (20%Zinc), were investigated in dry sliding conditions. Friction and wear experiments were conducted on pin-on-disc apparatus using composite pins against polished EN8 steel counterparts, performed within the pv-ranges at room temperature. It was found that conventional fillers, i.e SCF and graphite flakes could effectively enhance both...

Tribologische Untersuchung und Entwicklung eines Messing-Verbundlagers
ISBN: 9786206971689 / Niemiecki / Miękka / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Es ist notwendig, eine bessere Kombination von Metallmatrix-Festschmierstoffen zu finden, die als Festschmierstoff für verschiedene Anwendungen dienen. Durch das Mischen von Messing mit verschiedenen Füllstoffen wie MoS2. Graphitflocken und Submikropartikel aus MoS2 und Messing (20% Zink) wurden unter trockenen Gleitbedingungen untersucht. Reibungs- und Verschleißexperimente wurden mit Stift-auf-Scheibe-Geräten unter Verwendung von Verbundwerkstoffstiften gegen polierte EN8-Stahl-Gegenstücke durchgeführt, und zwar innerhalb der pv-Bereiche bei Raumtemperatur. Es wurde festgestellt, dass...
