Phyllanthus Niruri: A magic Herb
Medicinal herbs are significant source of pharmaceutical drugs. Latest trends have shown increasing demand of phytodrugs and some medicinal herbs have proven hepatotprotective potential. Inflammation describes a coordinated series of molecular, cellular, tissue, organ, and systemic responses that drive the pathology of various diseases Inflammation is a finely tuned, dynamic, highly-regulated process that is not inherently detrimental, but rather required for immune surveillance, optimal post-injury tissue repair, and regeneration. The inflammatory response is driven by cytokines and chemokines and is partially propagated by damaged tissue-derived products (Damage-associated Molecular Patterns; DAMP’s). DAMPs perpetuate inflammation through the release of proinflammatory cytokines, but may also inhibit anti-inflammatory cytokines
Bilinear generating relations for a family of q-polynomials and generalized basic hypergeometric functions
In this paper, we derive a bilinear q-generating function involving basic analogue of Fox's H-function and a general class of q-hypergeometric polynomials. Applications of the main results are also illustrated
Random matrix ensemble with random two-body interactions in presence of a mean-field for spin one boson systems
For number of bosons, carrying spin (=1) degree of freedom, in
number of single particle orbitals, each triply degenerate, we
introduce and analyze embedded Gaussian orthogonal ensemble of random matrices
generated by random two-body interactions that are spin (S) scalar
[BEGOE(2)-]. The embedding algebra is with SO(3) generating spin . A method for constructing the ensembles
in fixed-(, ) space has been developed. Numerical calculations show that
the form of the fixed-(, ) density of states is close to Gaussian and
level fluctuations follow GOE. Propagation formulas for the fixed-(, )
space energy centroids and spectral variances are derived for a general one
plus two-body Hamiltonian preserving spin. In addition to these, we also
introduce two different pairing symmetry algebras in the space defined by
BEGOE(2)- and the structure of ground states is studied for each paring
symmetry.Comment: 22 pages, 6 figure
Going 'Above and Beyond': Are Those High in Autistic Traits Less Pro-social?
Few studies have explored how the cognitive differences associated with autistic spectrum disorder translate into everyday social behaviour. This study investigated pro-social behaviour in students scoring high and low on the autism-spectrum quotient (AQ), using a novel scenario task: 'Above and Beyond'. Each scenario involved an opportunity to behave pro-socially, and thus required balancing the needs of a character against participants' own interests. High AQ participants both generated responses and selected courses of action that were less pro-social than those of the low AQ group. For actions of low pro-social value they gave higher self-satisfaction ratings; conversely, they gave lower self-satisfaction ratings for high pro-social actions. The implications for everyday functioning are considered for those with high autistic traits
q-Sumudu transforms pertaining to the product of family of q-polynomials and generalized basic hypergeometric functions
The prime objective of commenced article is to determine q-Sumudu transforms of a product of unified family of q-polynomials with basic (or q-) analog of Fox’s H-function and q-analog of I-functions. Specialized cases of the leading outcome are further evaluated as q-Sumudu transform of general class of q-polynomials and q-Sumudu transforms of the basic analogs of Fox’s H-function and I-functions
Soft Photocatalysis: Organic Polymers for Solar Fuel Productions
Solar fuel generation has attracted vast research interest as an environmentally benign means of producing energy from sunlight for catering to the ever growing world energy demands. As an alternative to inorganic semiconductors, organic polymers have entered the stage as promising photocatalytic systems offering a yet unprecedented scope for molecular engineering and precise tuning of optoelectronic properties. This perspective presents an overview of the development, state-of-the-art, and growth perspectives of this emerging field and highlights recent advances in photocatalyst design with a particular focus on structure property-activity relationships in structurally well-defined 2D polymers for hydrogen evolution
Null-Space Minimization of Center of Gravity Displacementof a Redundant Aerial Manipulator
Displacements of the base during trajectory tracking are a common issue in the control of aerial manipulators. These are caused by reaction torques transferred to the base due to the manipulator motion and, in particular, to the motion of its center of gravity. We present a novel approach to reduce base displacements of a kinematically redundant aerial manipulator by using null-space projection in the inverse kinematic control. A secondary objective function minimizes the horizontal displacement of the manipulator center of gravity. We test this algorithm on different trajectories for both three and four degrees of freedom (DOF) manipulators in a simulation environment. The results comparing our algorithm with inverse kinematic control without the null-space projection show up to an 80% reduction in the end-effector position error and an average of about 56% reduction in maximum base displacement. The simulation implementation also runs faster than in real-time in our code implementation. We provide a workspace analysis based on multiple stopping criteria such as excessive base displacement, joint velocities and end-effector position error for the 3 and 4 DOF manipulators. As expected, the 4 DOF manipulator has a larger workspace
Synthesis and Characterisation of Diaryl Furoxans
The paper discusses the synthesis, characterisation, and performance evaluation of diarylfuroxans namely, bis-phenyl-3,4-furoxan (5) and bis-(4’-nitrophenyl)-3,4-furoxan (6). Themolecules have been synthesised on the lines of reported method by cyclodimerisation of thenitrile oxides generated from benzaldoxime and p-nitro benzaldoxime, respectively. The synthesisedfuroxans (5 ) and (6) were characterised by the elemental analysis, UV, IR, and 1H NMRspectroscopy. The hazard characteristics (impact and friction sensitivity) confirm that thecompounds are safe to handle. The oxygen balance, velocity of detonation and detonationpressure have been computed. The detonation velocity and pressure along with oxygen balanceincreased with the substitution of nitro group in the benzene ring, as expected. Thethermogravimetric studies on promising compound (6) brings out that maximum weight lossoccurs at decomposition temperature of 259–260 °C
Optical gap in herringbone and pi-stacked crystals of 1]benzothieno3,2-b]benzothiophene and its brominated derivative
The optical gap of the organic semiconductor 1]benzothieno3,2-b]benzothiophene and its 2,7-dibrominated analogue is measured in solution and in the crystalline state by means of UV-vis and emission spectroscopy. Bromination leads to a change in molecular packing from herringbone to pi-stacked, resulting in a marked shift in the absorption and emission spectra which is found to be in accordance with TDDFT calculations
An overview of the predictors of symptomatic urinary tract infection among nursing students
Background: Urinary tract infection (UTI) is the most common infection experienced by humans after respiratory and gastro‑intestinal infections, and also the most common cause of nosocomial infections for patients admitted to hospitals indeed UTIs are the most frequent bacterial infection in women. Aim: The aim was to determine the prevalence of UTI and to identify factors associated with an increased risk of UTI among nursing students. Subjects and Methods: The cross‑sectional study involved 177 unmarried nursing students aged 18–30 years studying in the SRMSIMS, Nursing College Bareilly. A structured questionnaire was used, and study subjects were asked regarding the symptoms of UTI in the previous 3 months. Chi‑square test and Univariate Logistic Regression was used to analyze the data. Results: The overall prevalence of UTI was found to be 19.8% (35/177). Rural background, inadequate water intake, and unsatisfactory toilet habits were found to be strong predictors of UTI. Conclusions: There is an urgent need to sensitize the nursing students regarding the growing need of the issue so that they themselves become aware in addition to raising the awareness of other high‑risk groups.Keywords: Nursing students, Prevalence, Urinary tract infectio
