The modification of different zirconium propoxide and hafnium propoxide precursors with 2,2,6,6,-tetramethyl-3,5-heptanedione (Hthd) was investigated by characterization of the isolated modified species. The complexes [Zr(OnPr)3(thd)](2), [Zr(OnPr)(OiPr)2(thd)]2, Zr(OiPr)(thd)3, [Hf(OnPr)3(thd)]2, and Hf(OiPr)(thd)3 were isolated and characterized. The structure of the n-propoxide analogue of Z...
The rapid increase in the number of Electrical Vehicles (EVs) will bring difficulties management charging process and pose serious grid problems at low voltage levels. Particularly, with employment wireless power transfer (WPT) system a station, harmonic interference increase. main reason that poor quality lies on high frequency square wave output transmitter side WPT. In this study, support ve...
Although thalidomide (Thd) is being extensively investigated for its effects on cytokine production and T cell costimulation, it is poorly understood whether it is capable of modulating the activities of natural killer (NK) cells. In this study, Thd effects on NK cell activity were examined with a murine model of melanoma, which is mostly rejected by NK cell-dependent mechanism. Administration ...
<span lang="EN-US">The inverter has been attracting researchers for their application in renewable energy. So far, multilevel is considered as low distortion class, which produces output voltage imitating a pure sine waveform. However, the needs free of have motivating to improve pulse width modulation PWM generation method. In this paper, modified technique proposed reduce total harmonic...
Tiwai (Eleutherine americana Merr) is a medical plant which has indicated potentially as hypercholesterolemia medicine. This research was aimed to investigate the cholesterol-lowering ability of Tiwai Herbal Drink (THD) in human bloods. Two weeks clinical observation was conducted with 12 volunteers. The volunteers are in age between 40 and 65 years old with a cholesterol level above 220 mg/dL,...
Internal Liability of power system transmission lines influenced by the turbulences owing to catastrophic disasters. In order achieve Constant Voltage Stability at both ends lines, Static Synchronous Compensator (STATCOM) is imperative. source Converter mechanisms augment with switching frequency control methodologies are widely adopted regulate reactive power. By deliberating IEEE Standards, m...
Thalidomide (THD) exhibits antitumor effects in several types of cancer. However, the failure of THD to inhibit tumor growth has also been observed in a number of murine models in vivo. The mechanism involved in the therapeutic failure of THD remains unclear. The present study demonstrated that, accompanied by growth-arresting and apoptosis-inducing effects (P<0.05), THD upregulated vascular en...
In this paper, Artificial Neural Network (ANN) technique has been used for the estimation of voltage THD (Total Harmonic Distortion), current THD and power factor, mainly from input and output measurements of five different chorded induction motors fed from a pulse width modulation inverter voltage supply. A sinusoidal pulsewidth modulation (SPWM) inverter feeding five different chorded three-p...
Laser photoionization and ligand photodissociation in Ln(thd)(3) (Ln = Eu, Tb, Gd; thd = 2,2,6,6-tetramethyl-3,5-heptanedionato) are studied in a molecular beam via time-of-flight mass spectrometry. The fragmentation patterns are strongly wavelength dependent. With 355 nm excitation, the mass spectrum is dominated by Ln(2+), Ln(+), and LnO(+) fragments. The bare Ln ions are believed to arise fr...
