Extremal functions for the anisotropic Sobolev inequalities

The existence of multiple nonnegative solutions to the anisotropic critical problem - \sum_{i=1}^{N} \frac{\partial}{\partial x_i} (| \frac{\partial u}{\partial x_i} |^{p_i-2} \frac{\partial u}{\partial x_i}) = |u|^{p^*-2} u {in} \mathbb{R}^N is proved in suitable anisotropic Sobolev spaces. The solutions correspond to extremal functions of a certain best Sobolev constant. The main tool in our study is an adaptation of the well-known concentration-compactness lemma of P.-L. Lions to anisotropic operators. Futhermore, we show that the set of nontrival solutions \calS is included in $L^\infty(\R^N)$ and is located outside of a ball of radius $\tau >0$ in $L^{p^*}(\R^N)$

Indexación: Scopus.GSM thanks to the Department of Chemistry at the Universidad Andres Bello, Concepcion, Chile. LHMH gratefully acknowledges financial support from CONACYT (Projects CB2015-257823) and to the Universidad Autónoma del Estado de Hidalgo.Dye-sensitized solar cells (DSSCs) based on triphenylamine (TPA) as a donor group linked with the acceptor cyanoacrylic acid electron acceptor by 2,2'-bithiophene as π-bridged (D-π-A) has been investigated by Density Functional Theory (DFT) at the B3LYP/6-311G(d,p) level of theory, to establish the conformational orientation of cyanoacrylic acid group as well as evaluate the effect of planarizing the 2,2'-bithiophene unit in position 3 and 3' by electron withdrawing or donor groups on the electronic structure properties of ground and doping(n,p) states. Also, the Time Dependent Density Functional Theory (TD-DFT) at the CPCM-TD-CAM-B3LYP//CAM-B3LYP/6-311G(d,p) level of theory were selected to modulate the electronic absorption spectra and charge-transfer capabilities of the molecules analyzed in the present work. The results indicate that adding an auxiliary donor or withdrawing group to the 2,2'-bithiophene in the (D-π-A) arrangement allow to modify the LUMO's energy of the dyes, while the HOMO's energy is slightly affected. © 2018 Sociedade Brasileira de Quimica.

Internal Cash Flows, Insider Ownership, Investment Opportunity, Dan Capital Expenditures: Suatu Pengujian Terhadap Hipotesis Pecking Order Dan Managerial

The objectives of this study are to observe the impact of internal cash flows, insider ownership, and investment opportunity on the capital expenditure in two different theories. Those theories are: (1) the pecking order hypothesis and (2) the managerial hypothesis, tested in Indonesian case.On the one hand, the pecking order hypothesis postulates that managers can choose the level of capital expenditure to maximize the wealth of current shareholders without considering insider ownership in the company. On the other hand, according to the managerial hypothesis, managers whose ownership proportions are small tend to use higher level of internal cash flows to finance the capital expenditure than that which would maximize the wealth of current shareholders.This study is predicated on Griner and Gordon\u27s study (1995) and focused on manufacturing companies listed in BEJ. The data used in this study are taken from the period of 1993-1996. There are 64 companies chosen based on purposive sampling.The result of this study shows that the internal cash flows and the investment opportunity have positive and significant impact on the capital expenditures. However, the impact of insider ownerships on the capital expenditures is not significant. Eventually, this study substantiates the pecking order hypothesis

The Effects of Aqueous Extracts of Echium Amoenum and Citrus Aurantiflia on Blood Pressure and Heart Rate before and after phynelephrine Injection in Rat

Abstract: Background & Aims: Echium amoenum and Citrus aurantifolia are used in traditional medicine for the treatment of cardiac arrhythmia and regulation of blood pressure. In this study the effects of co-administration of these herbs on heart rate and blood pressure of rats before and after phynelephrine injection were investigated. Methods: Ten groups of rats respectively received 100, 200, 400 and 600 mg/kg Echium Amoenum, 250 mg/kg Citrus Aurantiflia and combination of 250 mg/kg Citrus Aurantiflia with 100, 200, 400 and 600 mg/kg Echium Amoenum for 6 days. Control group received water. Blood pressure and heart rate before and after phynelephrine injection were measured and compared among groups. Results: Echium amotnum at 400 and 600 mg/kg dozes significantly increased blood pressure of rats in comparison to the control group (P<0.05) and this effect was more significant after phynelephrine injection (P<0.05). Echium amoenum in combination whit citrus aurantiflia decreased heart rate after phynelephrine injection and also in comparison to the control group. This decreasing effect was more than the effect of 6.688 mg/kg phynelephrine (P<0.05). Conclusion: Since Echium amoentum has an increasing effect on blood pressure especially in higher blood pressures, it is not suggested for those with hypertension. Co-administration of Echium amoentum and Citrus aurantiflia is recommended for decreasing heart rate. Keywords: Blood pressure, Heart rate, Echium, Citrus aurantifoli
