In the present student, Sudan Orange G (SOG) [4-(Phenylazo)resorcinol] derivatives have been studied at Density Functional theory (TD-DFT) at B3LYP level of theory with 6-31G(d) basis set. Different substituent groups were introduced in different position to investigate their effects on the electronic and optical properties. The HOMO and LUMO energies and the energy gap (Egap) between HOMO and LUMO of the studied dyes were calculated. The light harvesting efficiency (LHE), the open-circuit voltage (Voc) and injection driving force (?Ginject) which are the key parameters related to the solar cell efficiency (?) were computed. The LHE values for the dyes are in different ranges and that all the dyes will give different photocurrent. The D6 dye has highest oscillator strength value 1.1263 and the LHE value is 0.925235. So the D6 dye has more efficiency than other studied dyes. Based on the values, the meta substituent dyes are better sensitizers compare to other dyes.

Liver hydatidosis is a considerable health problem in the developing countries, such as Iran. There are different therapeutic approaches for the treatment of this disease including; laparoscopy, open surgery, as well as puncture, aspiration, injection, and re-aspiration (PAIR) technique. Herein, we presented the case of two pediatric patients with multiple hydatid cysts in the liver, who were treated through the PAIR technique with no complication or relapse in the follow-up.

In the present study, the FT-IR and FT-Raman spectra of 2,4,6-Trimethylbenzaldehyde have been recorded in the region 4000–400 cm_1 and 3500–50 cm_1, respectively. The fundamental modes of vibrational frequencies of (TMB) are assigned. Theoretical information on the optimized geometry, harmonic vibrational frequencies, infrared and Raman intensities were obtained by means of ab initio Hartree–Fock (HF) and density functional theory (DFT) gradient calculations with complete relaxation in the potential energy surface using 6-31+G(d,p)) basis set. The vibrational frequencies which were determined experimentally from the spectral data are compared with those obtained theoretically from ab initio and DFT calculations. A close agreement was achieved between the observed and calculated frequencies by refinement of the scale factors. The infrared and Raman spectra were also predicted from the calculated intensities. Thermodynamic properties like entropy, heat capacity, zero point energy, have been calculated for the molecule. The calculated HOMO–LUMO energy gap reveals that charge transfer occurs within the molecule. Unambiguous vibrational assignment of all the fundamentals was made using the total energy distribution (TED).

Since the inception industrial revolution, a continuous attempt is being made to recover and minimize the waste heat. With the time various waste heat recovery system is developed. In the present research paper an exhaustive review on heat pipe is done. Various aspects and application is described and the view of authors is presented here. Further, the wide application of heat pipe to recover waste heat from the exhaust of IC engine id discussed and salient conclusion is drawn which indicates that, a wide scope is available for further research on heat pipe and especially in the relation of IC engine exhaust heat recovery system.

Jamming is defined as the act of intentionally directing electromagnetic energy towards a communication system to disrupt or prevent signal transmission. A jamming attacker launches jamming attacks easily by transmitting high-power signals and all legitimate sensor nodes interfered by jamming signals suffer corrupted packet transmissions. In this paper, model the interaction between the sensor network model and the attacker model as a non-cooperative non-zero-sum static game. In such a game, the sensor network has a set of strategies of controlling its probability of accessing the wireless channel and the attacker manipulates its jamming by controlling its jamming probability after sensing a transmission activity. The jammer action ceases when it is found by a monitoring node in the network, and an intimation of jamming message is transferred out of the jamming region. In this paper implements, algorithm for computing jamming attack and network defense. A critical issue is that there may exist a number of possible strategy profiles of Nash equilibria and its solve by applying Pareto-dominance and risk dominance.Results provide valuable insights about the structure of the jamming attack problem and associated defense policies and the adoption of sophisticated strategies on achieving desirable performance.

The quantification of primary metabolites and antimicrobial activities of medicinal plant Butea monosperma (Lam.) kuntze against clinical isolates was evaluated. The present study was aimed to determine the antibacterial and antifungal activities of the chloroform and ethanolic extract of leaf, flower, root and seed of the Butea monosperma (Lam.) kuntze. Antimicrobial activity was determined by using agar well diffusion method. Ethanolic extracts of leaves and flowers possessed highest antibacterial activity against E.coli and highest antifungal activity against Trichoderma ressi and Fusarium oxysporum. Chloroform extracts of seeds have the highest antibacterial activity against Bacillus subtilis and highest antifungal activity was observed in chloroform extracts against Fusarium oxysporum . The present results showed potential of this medicinal plant which can be used as herbal drug as therapeutic ventures in future aspects.

The objective of this paper is to investigate the relationship between individual’s absorptive capacity and innovative behavior among engineers in the electrical and electronic (E&E) sector in Malaysia. The study utilized survey method to collect the data. There were 305 responses for the survey. Partial least square (PLS) properties of structural equation modeling (SEM) were used to measure the relationships between the variables. The study found only partial support in absorptive capacity ability to influence innovative behavior.

The suitability and the performance of activated carbon produced from flamboyant pod back, milk bush kernel shell and rice husk for the effective removal of acenaphthene from simulated wastewater under the influence of carbonization temperature and initial concentration were investigated. The adsorption capacities of all the activated carbons obtained from the selected raw materials are influenced by increasing carbonization temperature. Activated carbons obtained from rice husk at carbonisation temperature of 600 0C had the maximum adsorption capacity (5.554 mg/g) while carbons produced from milk bush at carbonisation temperature of 300 0C had the minimum adsorption capacity (1.386 mg/g), for the adsorption of acenaphthene from the simulated wastewater. The removal efficiencies of the investigated adsorbents generally rank high and the highest value (80.56 %) was obtained for the adsorption of acenaphthene by rice husk carbonized at 600 0C. Furthermore, the removal efficiencies obtained in the study decreased as the initial concentrations of the adsorbate increased. The four selected isotherm models; Freundlich, Langmuir, Temkin and Dubinin-Radushkevich described well the equilibrium adsorption of acenaphthene unto activated carbon derived from Flamboyant pod bark, milk bush kernel shell and rice husk. Sequence of suitability of the selected isotherms in the study was Temkin ? Freundlich > Dubinin-Radushkevich > Langmuir for adsorption of acenaphthene. It therefore shows that Temkin isotherm is the most suitable model for fitting experimental data obtained from adsorption of acenaphthene from simulated wastewater unto activated carbon produced from Flamboyant pod bark, milk bush kernel shell and rice husk.

In this paper Bessel type differential operator and an n-dimensional pseudo-differential type operator involving the n-dimensional Hankel type transformation is defined. The symbol class is introduced. It is shown that pseudo-differential type operators associated with symbols belonging to this class are continuous linear mappings of the n-dimensional Zemanian space into itself. An integral representation for the pseudo-differential operator is obtained. By using the Hankel type convolution, it is shown that the pseudo-differential type operator satisfies a certain norm inequality.
