Charged particles in a rotating magnetic field

We study the valence electron of an alkaline atom or a general charged particle with arbitrary spin and with magnetic moment moving in a rotating magnetic field. By using a time-dependent unitary transformation, the Schr\"odinger equation with the time-dependent Hamiltonian can be reduced to a Schr\"odinger-like equation with a time-independent effective Hamiltonian. Eigenstates of the effective Hamiltonian correspond to cyclic solutions of the original Schr\"odinger equation. The nonadiabatic geometric phase of a cyclic solution can be expressed in terms of the expectation value of the component of the total angular momentum along the rotating axis, regardless of whether the solution is explicitly available. For the alkaline atomic electron and a strong magnetic field, the eigenvalue problem of the effective Hamiltonian is completely solved, and the geometric phase turns out to be a linear combination of two solid angles. For a weak magnetic field, the same problem is solved partly. For a general charged particle, the problem is solved approximately in a slowly rotating magnetic field, and the geometric phases are also calculated.Comment: REVTeX, 13 pages, no figure.

Twitter for University using Cloud

In this paper, we present a project that would provide twitter like website for a university purpose intended to use by the students, professors of the colleges in the University and a University Admin. The University admin will provide with all the necessary notifications regarding the events in the University for the students and professors like result notifications, timetables, events, fees, important dates, etc. The students and staff can follow the University Admin and get the necessary notifications just by logging into their accounts and viewing their home pages. Moreover, this project would be deployed on the cloud which would make this website available 24x7 and will reduce the overhead cost of maintaining the expensive servers for the University. This project aims at utilizing the social networking and technology for educational purposes and to improve the student-teacher interaction off the classroom.

Estimation of total phenolic, total flavonoid content and evaluation of anti-inflammatory and antioxidant activity of Ixora coccinea Linn. stems

Ixora coccinea Linn. (Rubiaceae) has mentioned in Ayurveda as Paranti and traditionally stems used in inflammatory diseases like sprains, eczema, contusions and boils.  Present study deals with evaluation of anti-inflammatory and antioxidant activity of extracts of I.coccinea stem. Anti-inflammatory activity was studied in vivo by carrageenan-induced paw edema in rat and in vitro by human red blood cell membrane stabilization method. Total tannin and flavonoid content of extracts was determined by using the Folin- Ciocalteu method and aluminum chloride method, respectively. Antioxidant activity was evaluated by in vitro assay involving nitric oxide scavenging, hydrogen peroxide scavenging, 2,2-  diphenylpicrylhydrazyl (DPPH) radical scavenging, and ion chelating activity. Chloroform extract showed significant reduction in carrageenan induced rat paw edema (p<0.05) and protection of HRBC in hypotonic solution. Methanol extract contain more total tannin and flavonoid content as compared with petroleum ether and chloroform extract. All extracts showed concentration dependant free radical scavenging activity. Methanol extract and chloroform extract have shown better antioxidant activity and due to this antioxidant nature might be responsible for its anti-inflammatory activity. These activity supports to use of I.coccinea extract in traditional used in treatment of various inflammatory disaeses

Hyphomycetes from north Maharashtra

The present paper deals with five species of Dematiaceous Hyphomycetes were collected from the submerged wood samples from the various water bodies in North Maharashtra region. Two species viz. Camposporidium cristatum Nawawi and Kuthubutheen and Dictyosporium guanttii Bhat and Sutton are being recorded for the first time form India. While Bactrodesmium indicum Udaiyan and Diplocladiella longibrachiata Nawawi & Kuthubutheen are being reported  for the first time from Maharashtra state. Brief notes and illustration are given for each taxon. Geographical distribution of each species in India is also provided

Performance Analysis of MUSIC and Smooth MUSIC Algorithm for DOA Estimation

Smart Antenna Systems is one amongst speedily developing areas of wireless communication. With effective direction of arrival (DOA) and Beam forming techniques Smart Antenna Systems persuade is most effective in terms of quality of signals in wireless communication. This paper analyzed and compares the performance of MUSIC and Smooth MUSIC DOA estimation algorithm on the uniform linear array (ULA) which are used in design of smart antenna system. MUSC algorithm is high resolution subspace based method which is used for DOA estimation of uncorrelated signals while smoothing of MUSIC is introduced for DOA estimation of completely correlated signal. The angular resolution of DOA estimation techniques improves as number of elements in array, snapshots and values of SNR increases. DOI: 10.17762/ijritcc2321-8169.15071

Impact of PowerPoint and Chalkboard teaching in Physiotherapy Undergraduates.

Background: A teacher\u27s basic tool for displaying lectures are through blackboards, pegboards, bulletin boards, transparencies with an overhead projector (TOHP), PowerPoint presentation and walk and talk. Nowadays PowerPoint presentation is commonly used as it has ability to present the information in a clear, organized and simpler manner. The present study was carried out to find out the best method of teaching amongst the undergraduate Physiotherapy students. Objective: To compare the impact of the PowerPoint multimedia presentation and chalkboard in teaching by assessing the knowledge based on the marks obtained in the pretest and posttest. Methodology: 40 students were divided into two groups and a selected content-based lecture in pharmacology was delivered. For one group lecture was delivered using PowerPoint presentation, for second group using Chalkboard. Single - best Multiple Choice Questions [MCQs] paper was used for assessing the knowledge gained. The differences in the marks obtained in the two groups were analyzed Results: Students who attended the class on chalkboard obtained significantly higher score in single best MCQ examination compared to those students who attended the same content based lecture on the PowerPoint. Conclusion: The chalkboard method of teaching was found more suitable tool of teaching and learning than PowerPoint for small group

Geometric Phases and Multiple Degeneracies in Harmonic Resonators

In a recent experiment Lauber et al. have deformed cyclically a microwave resonator and have measured the adiabatic normal-mode wavefunctions for each shape along the path of deformation. The nontrivial observed cyclic phases around a 3-fold degeneracy were accounted for by Manolopoulos and Child within an approximate theory. However, open-path geometrical phases disagree with experiment. By solving exactly the problem, we find unsuspected extra degeneracies around the multiple one that account for the measured phase changes throughout the path. It turns out that proliferation of additional degeneracies around a multiple one is a common feature of quantum mechanics.Comment: 4 pages, 4 figures. Accepted in Phys. Rev. Let
