Opis:: The research is undertaken to investigate the impact of brand equity on consumer willingness to pay the premium price by using an extended model of the theory of planned behavior. Role of consumer attitude, subjective norms, and perceived behavioral controls in shaping consumer intention towards paying a premium price for a brand are explored. The theory is further extended to demonstrate the role of brand equity towards consumer intention to pay a premium price. This research is conducted explicitly in Pakistan. The data was analyzed statistically by performing regression analysis with SPSS. The findings indicate that there is a significant impact of brand equity, attitude, subjective norms, and perceived behavioral controls on consumer intention to pay a premium price for the brand. The research findings depict that consumers are willing to pay a premium price for a brand if the high brand equity is established.
Podjęte badania mają na celu przeanalizowanie wpływu wartości marki na skłonność konsumentów do płacenia ceny premium za pomocą rozszerzonego modelu teorii planowanych zachowań. Dokonano analizy roli postawy konsumenckiej, subiektywnych norm i postrzeganych kontroli behawioralnych w kształtowaniu intencji konsumenta w zakresie płacenia wyższej ceny za markę. Teoria ta jest dalej rozwijana, aby pokazać rolę marki w dążeniu konsumenta do zapłacenia wyższej ceny. Badania wykorzystane w niniejszym artykule przeprowadzono w Pakistanie. Dane analizowano statystycznie, przeprowadzając analizę regresji za pomocą oprogramowania SPSS. Ustalenia wskazują, że istnieje znaczący wpływ wartości marki, postawy, subiektywnych norm i postrzeganych kontroli behawioralnych na intencję konsumenta, aby zapłacić wyższą cenę za markę. Wyniki badań wskazują, że konsumenci są gotowi zapłacić wyższą cenę za markę, jeśli ustanowiony zostanie wysoki kapitał własny marki.

Opis:: Abstract A novel floating controlled release drug delivery system of Sitagliptin phosphate was formulated in an effort to increase the gastric retention time of the dosage form and thereby increased drug bioavailability. The tablets were prepared by wet granulation method using Psyllium Husk and tragacanth gum as a release retarding polymers and sodium bicarbonate as a gas generating agent. All the designed nine batches of floating tablets were evaluated for physical characteristics viz. weight variation, thickness, content uniformity, hardness, floating capacity, swelling studies. All formulations had floating lag time of less than 1 min and constantly floated for 12 h except F1, F4 and F7 (that dissolved completely in 8 h or less than 8 h). In vitro drug release studies were carried out for 8 h and release mechanism was further evaluated by linear regression analysis, F9 composed of 30% Psyllium Husk, 10% tragacanth gum and 18% sodium bicarbonate sustained the drug release for longer period. The formulations followed first order kinetics, Higuchi drug release kinetics with diffusion as the dominant mechanism of drug release and the release exponent ranged (0.452-0.635) indicating that the drug release from all formulations was by non-Fickian diffusion mechanism. The prepared floating tablets of STP (F9) might be a promising drug delivery system with sustained release action and improved bioavailability.

Opis:: Hematite $(α-Fe_{2}O_{3})$ nanoparticles and hematite nanoparticles coated with polyvinylpyrrolidone (PVP) are synthesized chemically by co-precipitation. Prolysis and microemulsion methods respectively. An average size of nanoparticles (both coated and uncoated) was found by the broadening of the X-ray diffraction peaks using Scherrer's formula. It was found that coating reduced particle sizes. The attachment of the polymer on the surface of particles was confirmed by the Fourier transform infrared spectroscopy and thermogravimetric analysis. Optical ultraviolet/visible reflectance test also indicated the presence of PVP in coated nanohematites. In magnetic studies, it was observed that coating does not change main magnetic character of the $α-Fe_{2}O_{3}$ nanoparticles however it reduces DC magnetization (as a function of applied field and temperature) to a considerable amount. Moreover it was observed that after coating Morin transition temperature $T_{M}$ and its width $ΔT_{M}$ shifts to lower values, which is another indication of size reduction.

Opis:: The effect of particle size on the magnetic and optical properties of cobalt oxide $Co_3O_4$ has been investigated. Single phase $Co_3O_4$ nanoparticles were synthesized by co-precipitation route and their structure was confirmed through X-ray diffraction analysis. The average crystallite sizes of the nanoparticles as determined from the X-ray diffraction were found to lie in the range of 13 to 59 nm. At room temperature these particles show paramagnetic response and the DC magnetic moment of the samples showed an increasing trend with increasing particle size. Both the antiferromagnetic Néel temperature $T_{N}$ and the low temperature moment depict finite size effects in the AC susceptibility measurements. The optical absorption studies show that there are two direct band gaps in $Co_3O_4$, the main energy band gap and a sub-band located inside the main energy gap. The values of these energy band gaps for the 45 nm particles were determined to be 3.15 and 1.76 eV, respectively. The direct band gap in these particles clearly shows a blue shift with decreasing size attributable to the quantum confinement effect.
