An overview of Natural Medicinal Plant Extraction, Isolation and Characterization Methods in Improvement of Medicinal Research

: Our plant biodiversity and conservation are greatly enhanced by the usage of medicinal herbs in traditional community practices. Natural products are essential components of traditional knowledge systems in nutraceuticals, food supplements, pharmacological bioactive metabolites of novel chemical entities, and complementary and alternative medicine. Due to the vast flora and fauna biodiversity that generates the requisite accessible chemical diversity, bioactive secondary metabolites from herbal plants of various kinds are key sources and offer major prospects for medication active pharmaceuticals. This paper is aimed to shed light on the fundamental principle of drug discovery from plants are procedure of extraction, isolation and characterization of molecules from plant tissue. These methods have been used in research, and publications on the subject are accessible. However, it is crucial to combine them and talk about their core definitions, including contrastive benefits and drawbacks. Students, researchers and project managers can choose the strategies to use in their projects by conducting a basic literature study of the techniques that are routinely used in drug discovery from natural sources.
Analysis of Thundersnow Storms over Northern Colorado

ABSTRACTLightning flashes during snowstorms occur infrequently compared to warm-season convection. The rarity of such thundersnow events poses an additional hazard because the lightning is unexpected. Because cloud electrification in thundersnow storms leads to relatively few lightning discharges, studying thundersnow events may offer insights into mechanisms for charging and possible thresholds required for lightning discharges. Observations of four northern Colorado thundersnow events that occurred during the 2012/13 winter are presented. Four thundersnow events in one season strongly disagrees with previous climatologies that used surface reports, implying thundersnow may be more common than previously thought. Total lightning information from the Colorado Lightning Mapping Array and data from conterminous United States lightning detection networks are examined to investigate the snowstorms’ electrical properties and to compare them to typical warm-season thunderstorms.

Multi-UAV Trajectory Planning in Unknown Environments with Limited Information Sharing

A system composed of multiple UAVs can solve several complex tasks which are either difficult or unfeasible with a single UAV. Safe and fast operation are crucial when multiple UAVs are simultaneously working in a shared environment. This thesis focuses on studying and developing a method for collision-free trajectory planning by a multi-UAV system. The proposed method uses sensors on-board the UAV to create an online map of the environment and detect the motion of other UAVs. These detections are employed to predict the future trajectory of the UAVs. The map along with the predicted trajectories is used to design a collision-free trajectory to a pre-specified goal. The proposed method is decentralized and does not require any prior information about the environment or other UAVs which makes it easier to scale to large multi-UAV systems. The method is also independent of any external localization infrastructure making it ideal for real-world applications.
A mover-stayer mixture of Markov chain models for the assessment of dedifferentiation and tumour progression in breast cancer

Malignancy grade is a histological measure of attributes related to a breast tumour's aggressive potential. It is not established whether the grade is an inate characteristic which remains unchanged throughout the tumour's development or whether it evolves as the tumour grows. It is likely that a proportion of tumours have the potential to evolve, and so a statistical method was required to assess this hypothesis and, if possible, to estimate the proportion with the potential for evolution. Therefore, a mover-stayer mixture of Markov chain models was developed, with the complication that 'movers' were unobservable because tumours were excised on diagnosis. A quasi-likelihood method was used for estimation. The methods are demonstrated using data from the Swedish twocounty trial of breast-cancer screening.
Correction of Dielectric Losses in Practical Leaky-wave Antenna Designs

In this paper, the leaky-mode theory is applied to take into account for the dielectric losses in millimetre waveband inhomogeneous leaky-wave antennas. A practical dielectric-filled cosine-tapered periodic leaky-wave antenna working in the 45 GHz band is studied, showing how the desired sidelobes level and directivity are spoilt due to the effect of the losses. An iterative procedure is used to correct the negative effects of the losses in the radiation patterns of the leaky-wave structure. It is also shown the practical limits of the proposed correction approach. The leaky-mode theory is applied for the first time to compensate the losses in a practical leaky-wave antenna in hybrid waveguide printed circuit technology. This leaky-mode theory is validated with full-wave three-dimensional finite element method simulations of the designed antenna.
The Relationship Between Corporate Social Responsibility and Customer Purchase Intention: Empirical Evidence from Vietnam

Corporate social responsibility is becoming increasingly important to organizations, and it has received a lot of attention from the general public and marketing academics. This study aimed to look at the many aspects of corporate social responsibility and see how brand reputation and brand love play a role in the relationship between corporate social responsibility and customer purchase intent. To reach the end, this research applied the theory of social exchange and corporate social responsibility to explain the relationship between the variables. The Partial Least Squares was applied to analyze data collected from survey questionnaires in the Hanoi market (Vietnam) to test the proposed hypothesis. The study resulted in 239 valid survey questionnaires which can be used to test hypotheses by applying SmarPLS software. The results indicated that there are three key elements of corporate social responsibility from customers’ perspectives: responsibility to customers, responsibility to the environment, and responsibility to the community. Interestingly, brand reputation and brand love contribute as mediating roles in the correlation between corporate social responsibility and customer purchase intention. Finally, the authors discussed the findings and the implications of this research in both theoretical and practical aspects, as well as the limitations that future research can focus on.
Recent magneto-inertial fusion experiments on the field reversed configuration heating experiment

Magneto-inertial fusion (MIF) approaches take advantage of an embedded magnetic field to improve plasma energy confinement by reducing thermal conduction relative to conventional inertial confinement fusion (ICF). MIF reduces required precision in the implosion and the convergence ratio. Since 2008 (Wurden et al 2008 IAEA 2008 Fusion Energy Conf. (Geneva, Switzerland, 13–18 October) IC/P4-13 LA-UR-08-0796) and since our prior refereed publication on this topic (Degnan et al 2008 IEEE Trans. Plasma Sci. 36 80), AFRL and LANL have developed further one version of MIF. We have (1) reliably formed, translated, and captured field reversed configurations (FRCs) in magnetic mirrors inside metal shells or liners in preparation for subsequent compression by liner implosion; (2) imploded a liner with interior magnetic mirror field, obtaining evidence for compression of a 1.36 T field to 540 T; (3) performed a full system experiment of FRC formation, translation, capture, and imploding liner compression operation; (4) identified by comparison of 2D-MHD simulation and experiments factors limiting the closed-field lifetime of FRCs to about half that required for good liner compression of FRCs to multi-keV, 1019 ion cm−3, high energy density plasma (HEDP) conditions; and (5) designed and prepared hardware to increase that closed-field FRC lifetime to the required amount. Those lifetime experiments are now underway, with the goal of at least doubling closed-field FRC lifetimes and performing FRC implosions to HEDP conditions this year. These experiments have obtained imaging evidence of FRC rotation, and of initial rotation control measures slowing and stopping such rotation. Important improvements in fidelity of simulation to experiment have been achieved, enabling improved guidance and understanding of experiment design and performance.
Preprocessing for Interference Fringe of Spherical Object Wave

A simple preprocessing method for interference fringe of holograms generated between spherical object wave fronts and plane wave reference is suggested. The formulae to calculate the diameters of the interference concentric circle and then to get the radius of spherical wave are deduced strictly and the flowchart for the algorithm is given clearly. By using the proposed method the characteristics of a spherical object wave can be achieved directly with only one recording frame and then a simulated one can be gained by numerical simulation. The corresponding experiments show that this technique is simple, effective and convenient for use.

Computational study of a new resonant tunneling diode based on an MoS 2 nanoribbon with sulfur line vacancies

Recent experimental studies have shown that sulfur vacancies in monolayer MoS 2 are mobile under exposure to an electron beam and tend to accumulate as sulfur line vacancies (Komsa in Phys Rev B 88: 035301, 2013). In this work, we designed a new resonant tunneling diode (RTD) based on this natural property. Two rows of sulfur vacancies are introduced into armchair MoS 2 nanoribbons (A-MoS 2 NRs) to tune the nanoribbons’ bandgap to obtain the double-barrier quantum well structure of the resonant tunneling diode. This arrangement has a unique beneﬁt that will result in very little physical distortion. A tight-binding (TB) model, with ﬁve 4 d -orbitals of the Mo atom and three 3 p -orbitals of the S atom, is employed for calculations. In the TB model, which is described in terms of Slater–Koster parameters, we also incorporate the changes of edge bonds. Density func-tionaltheoryisusedtodetermineallthenecessaryparameters of the TB model. They are obtained by an optimization pro-cedure which achieves very ﬁne parameter values, which can regenerate the most important energy bands of A-MoS 2 NRs of different widths, with highly satisfactory precision. The introduction of these new parameters is another contribution of this work. Lastly, the nonequilibrium Green’s function formalism based on the TB approximation is used to explore the properties of the new RTD structures based on A-MoS 2 NRs. Negative differential resistance with peak to valley ratio (PVR) of about 78 at room temperature is achieved for one RTD, having peak current I p = 90nA. We show that the B M. Shariﬁ
Design studies of superconducting generators

An Electric Power Research Institute sponsored study of superconducting, central-station turbine-generators of 300 and 1200 MVA rating has been completed at General Electric. A unique construction concept is used for the superconducting field winding. The goal of this construction is to ensure that the winding can be energized to the current and flux density predicted by the superconductor short-sample data, without the "training" instabilities frequently encountered in large coils. The remainder of the rotor components includes an aluminum radiation shield and a compound, steel-aluminum electromagnetic shield, designed to withstand short circuit electromagnetic forces. The study was focused on generator model configurations which were proportioned to have a low transient reactance, approximately 0.2 per unit. The critical clearing times calculated for these configurations were comparable to those of conventional units, the low reactance offsetting an inherently lower rotor inertia. These generator configurations are estimated to have about half the size and weight, and about half the losses of conventional units of the same rating. Transient characteristics are described, including the effect of the rotor shielding configuration on rotor damping.
Detailed Investigation of Detached-Eddy Simulation for the Flow Past a Circular Cylinder at Re=3900

The flow past a circular cylinder at a subcritical Reynolds number 3900 was simulated by the method of detached-eddy simulation (DES). The objective of this present work is not to investigate the physical phenomena of the flow but to study modeling as well as numerical aspects which influence the quality of DES solutions in detail. Firstly, four typical spanwise lengths are chosen and the results are systematically compared. The trend of DES results along the span increment is different from previous large-eddy simulation (LES) investigation. A wider spanwise length does not necessary improve the results. Then, the influence of mesh resolution is studied and found that both too coarse and over refined grids will deteriorate the performance of DES. Finally, different orders of numerical schemes are applied in the inviscid fluxes and the viscous terms. The discrepancies among different schemes are found tiny. However, the instantaneous flow structures produced by 5th order WENO with 4th order central differencing scheme are more abundant than the others. That is, for the time-averaged quantities, the second-order accurate schemes are effective enough, whereas the higher-order accurate methods are needed to resolve the transient characteristics of the flow.
Radiative Accelerations on Iron Using Opacity Project Data

Radiative accelerations have been calculated in detail for iron in main-sequence models with T eff =6700, 8000, and 10,000 K and log g=4.0 and 4.3 and a number of Fe abundances. Atomic data for Fe IX to Fe XVII were taken from the Opacity Project, and this allowed us to calculate the accelerations over an important fraction of the envelope and to calibrate formulae that were obtained earlier using data from the first few states of ionization. We have derived approximate formulas that allow our results to be used in stellar evolution calculations. From a comparison of radiative acceleration and gravity, one may conclude that only small Fe abundance anomalies are to be expected in those stars with T eff =6700 K where atomic diffusion is important
A spectral deferred correction strategy for low Mach number reacting flows subject to electric fields

We propose an algorithm for low Mach number reacting flows subjected to electric field that includes the chemical production and transport of charged species. This work is an extension of a multi-implicit spectral deferred correction (MISDC) algorithm designed to advance the conservation equations in time at scales associated with advective transport. The fast and nontrivial interactions of electrons with the electric field are treated implicitly using a Jacobian-Free Newton Krylov approach for which a preconditioning strategy is developed. Within the MISDC framework, this enables a close and stable coupling of diffusion, reactions and dielectric relaxation terms with advective transport and is shown to exhibit second-order convergence in space and time. The algorithm is then applied to a series of steady and unsteady problems to demonstrate its capability and stability. Although developed in a one-dimensional case, the algorithmic ingredients are carefully designed to be amenable to multi-dimensional applications.
Atomistic tight-binding simulations of quaternary-alloyed Zn x Cd 1 − x S y Se 1 − y nanocrystals

Advancement of alloyed nanocrystals with attractive structural and optical properties for use in a wide range of physical, chemical, and biological applications represents a growing research ﬁeld. Employing atomistic tight-binding theory combined with the virtual crystal approximation, the electronic structure and optical properties of quaternary-alloyed Zn x Cd 1 − x S y Se 1 − y nanocrystals with experimentally synthesized compositions ( x and y ) and sizes were investigated. Analysis of the results shows that the physical properties are mainly sensitive to the concentrations ( x and y ) and the diameter. With decreasing x and y contents, the optical bandgap is reduced because the contributions of the materials with narrower bulk bandgap (ZnSe and CdSe) is mostly promoted. The optical bandgap is reduced with increasing diameter due to the quantum conﬁnement effect. The optical bandgap calculated based on tight-binding calculations shows discrepancy of less than 0 . 4eV from experiment. Most importantly, the optical emission is continuously tunable across the entire visible spectrum. The conduction and valence bands are predominantly contributed by cation and anion atoms, respectively. The optical properties are obviously improved in Cd- and Se-rich quaternary Zn x Cd 1 − x S y Se 1 − y nanocrystals with large diameter. The atomistic electron–hole interactions can be hybrid-engineered by tuning either the contents ( x and y ) or diameter. The Stokes shift becomes more pronounced with decreasing alloy concentrations ( x and y ) and diameter, as described by the trend of the atomistic electron–hole exchange interaction. The present systematic study provides a new avenue to understand the unique size- and composition-dependent structural and optical properties of quaternary-alloyed Zn x Cd 1 − x S y Se 1 − y nanocrystals for broad use in multicolor bioimaging, biosensing
Filament-to-dielectric band alignments in TiO 2 and HfO 2 resistive RAMs

The next-generation nonvolatile memory storage may well be based on resistive random access memories (RRAMs). TiO 2 and HfO 2 have been widely used as the resistive switching layer for RRAM devices. However, the electronic properties of the ﬁlament-to-dielectric interfaces are still not well understood yet, compared to those of the electrodes and the dielectric. In this work, we study the electronic structures of three typical ﬁlament and dielectric structures, Ti 4 O 7 / TiO 2 , Hf 2 O 3 / HfO 2 and Hf / HfO 2 , using ab initio calculations. We implement the GGA-1/2 method, which rectiﬁes the band gaps of GGA through self-energy correction. Our calculation predicts an ohmic contact for the Ti 4 O 7 / TiO 2 interface, where the defective Ti 4 O 7 phase was experimentally identiﬁed as the ﬁlament composition in TiO 2 . However, there is a ﬁnite Schottky barrier existing in either Hf 2 O 3 / HfO 2 interface (1.96eV) or Hf / HfO 2 interface (0.61eV), the two probable ﬁlament–dielectric con-ﬁgurations in hafnia-based RRAM. Our results suggest that the distinct ﬁlament-to-dielectric band alignments in TiO x and HfO x systems account for the much larger resistance window for the latter.
A versatile microelectromechanical system for nanomechanical testing

This letter presents a microelectromechanical system (MEMS) material testing setup that relies on electronic measurements of nanospecimen elongation. Compared to previously demonstrated MEMS that rely on high magnification images to measure elongation, this MEMS is more versatile, allowing both in situ and ex situ testing of nanomaterials with high accuracy and precision. We describe and characterize the MEMS device and illustrate its mode of operation with a successful ex situ uniaxial tensile test of a nanocrystalline nickel nanobeam. The combination of ex situ and in situ nanomechanical tests will enable a thorough investigation of critical properties pertaining to the reliability of nanosystems.
An Ionization Cone and Dusty Disk in Markarian 348: The Obscuring Torus Revealed?

We report on optical emission-line and near-infrared continuum images of the Seyfert 2 galaxy Mrk 348 (NGC 262). The optical images reveal a well-defined region of highly ionized gas aligned approximately north-south (i.e., along the radio axis), possibly in the form of a bicone. In addition, there is a red linear structure in the infrared continuum, oriented perpendicular to this axis and approximately 1 kpc in extent. We examine the possibility that this latter structure is emission from hot (~750 K) dust in a disk or torus viewed approximately edge-on. This disk may comprise the outer parts of the “dusty torus” postulated in schemes to unify the two types of Seyfert galaxies. The featureless continuum may come from hot stars associated with a 4 kpc diameter ring of H II regions surrounding the nucleus.
Lattice dynamics and thermodynamic properties of alkaline-earth metal carbides XC (X = Ca, Sr and Ba) in the rocksalt structure: a ﬁrst-principles study

Usingtheplanewavepseudopotentialapproachto density functional theory within the generalized gradient and local density approximations, we investigated the structural, electronic, magnetic, lattice-dynamics, and thermodynamic properties of rocksalt alkaline earth metal carbides CaC, SrC, and BaC. The phonon dispersion spectra were investigated by using the linear response to density functional theory within generalized gradient approximation. The quasiharmonic approximation allowed us to calculate the evolution with temperature of some fundamental thermodynamic properties such as heat capacity, vibrational entropy, internal energy, free energy of vibration, mean squared displacement, and thermal expansion coefﬁcient.
