Professional development programmes and skill development of librarians
The paper gives an overview of studies in professional development of the library staff which is important as new changes is taking place in libraries due to technological innovations. This makes itnecessary for the library staff to perceive professional development to adapt to the new changes. Thestudies particularly highlights need and importance of professional development programmes, various means of attaining such programmes as well. It also gives the insights about professional development programmes and its effects on skills of the librarians

A Study on ICT based Library Services with Reference to Academic Libraries in Rural Area
The present study gives an overview of ICT based library services in AICTE approved institutes of rural area of eastern part of Pune district. The findings of the study revealed that basic ICT equipment's and technology is available in the majority of libraries under study. These libraries provide ICT based services like OPAC,Reprographic service,access to full text databases, etc.,but services through digital library and institutional repository are lacking. The majority of librarians having knowledge of softwares for providing services. The libraries were facing problems like inadequate library budget and insufficient trained staff
Indigenous traditional practices for eco-friendly management of insect/pest in Maharashtra, India
An ethnobotanical study on plants used for indigenous traditional management of insects pests by people in Maharashtra was conducted to document the information particularly associated with the use as insecticide and pesticide potential of plants. In this study, following areas from the Maharastra were worked out, Ratnagiri, Raigad and Sindhudurg of Konkan, Toranmal and Dhadgaon areas in Nandurbar district, some areas in Nasik and Ahemdnagar districts. People residing in the villages and nearby forests depends mostly on traditional management of household insects, pests through their own methods use different plants, plant parts, etc. The present paper deals with the plants used to control insects and pests by the people of Maharashtra. A total of 84 plants belonging to 40 families have been documented for their insecticidal/pesticidal potential. Of these, families with more number of species used as insecticide or pesticide are, Fabaceae with 10 species; Lamiaceae with 8 species; Euphorbiaceae with 6 and Asteraceae with 5 species
“STRUCTURAL PROPERTIES OF HOLMIUM DOPED COBALT FERRITE BY STANDARD CERAMIC TECHNIQUE”
Objective: Compositions of CoHoxFe2-xO4 (x = 0.00 and 0.02) was prepared by standard ceramic technique using AR grade CoO2, Ho2O3 and Fe2O3. The samples were characterized by X-ray diffraction technique and the analysis of XRD patterns reveals the formation of single phase cubic spinel structure. The structural parameters like lattice constant (a), x- ray density(dx), bulk density (dB), particle size (t) and porosity (P), tetrahedral and octahedral bondlength (dAX and dBX), the tetrahedral edge (dAXE), and the shared and unshared octahedral edge (dBEX and dBXEU) can be calculated were calculated form XRD data and effect of Ho3+ doped cobalt ferrite was studied. Thus, the rare earth Ho3+ doped cobalt ferrite strongly influences the physical properties of cobalt ferrite.
Materials and Methods: Present series was prepared by standard ceramic technique using AR grade CoO2, Ho2O3 and Fe2O3.
Results: The XRD pattern shows that both the samples possess single phase cubic spinel structure. No extra peak of Ho3+ is observed for x =0.02 sample. Lattice constant, X-ray density of Ho3+ doped cobalt ferrite is increases than that of pure cobalt ferrite.
Conclusion: The rare earth Ho3+ doped cobalt ferrite strongly influences the physical properties of cobalt ferrite
ELECTRICAL CONDUCTION, dielectric BEHAVIOR AND MAGNETOELECTRIC EFFECT IN (1-x) Co1.2Mn0.2Fe1.6O4 + (x) BaTiO3 ME Composites
Objective: Electrical and magnetoelectric properties of magnetoelectric (ME) composites ferroelectric as electric component and a mixed ferrite as magnetic component are reported. The (1-x) Co1.2Mn0.2Fe1.6O4 + (x) BaTiO3 magnetoelectric (ME) composite have been prepared using conventional double sintering ceramic process where x varies as 0.00, 0.25, 0.50, 0.75 and 1.00. The X-ray diffraction pattern of the composites reveals the formation of spinel structure for the piezomagnatic phase and tetragonal perovskite structure for the piezoelectric phase without any other phase formation. The dc resistivity was measured as a function of temperature. The variation of dielectric constant ' dielectric loss ε'' and dielectric loss tangent δ with frequency in the range 1kHz-1MHz was studied. The dielectric constant shows dispersion in the lower frequency region, with almost a constant value at higher frequencies. The magnetoelectric voltage coefficient (dE/dH)H was studied as a function of intensity of the magnetic field. The measured magnetoelectric (ME) response demonstrated strong dependence on the volume fraction of CoMnFe2O4 and the applied magnetic field. A large ME voltage coefficient of about 647 Vcm-1Oe-1 was observed for 25% CoMnFe2O4 + 75% BaTiO3composite.
Materials and Methods: The piezoelectric phase Barium Titanate (BaTiO3) was prepared by standard doubling sintering ceramic method using AR grade oxides/carbonate. Barium carbonate (BaCO3) and Titanium-dioxide (TiO2) were taken in molar proportion.
Results: The electrical resistivity of ferrite phase is less as compared to the resistivity of ferroelectric material. The resistivity of composites is found to be in between ferrite and ferroelectric.
Conclusion: Magneto-electric conversion factor with varying magnetic field shows maxima in the curve at a lower magnetic field and then decreases continuously at higher magnetic field. As ferroelectric content increases both the resistivity and magnetoelectric conversion factor also increases
SIMULTANEOUS ESTIMATION & VALIDATION OF PARACETAMOL, PHENYLEPHRINE HYDROCHLORIDE AND CHLORPHENIRAMINE MALEATE IN TABLETS BY SPECTROPHOTOMETRIC METHOD
The present work describes two methods for simultaneous estimation of phenylephrine hydrochloride and chlorpheniramine maleate in pure and solid dosage forms. First method employs the application of simultaneous equation and second, is a multi-wavelength spectrophotometric analysis method. Both methods utilize 0.1N NaOH as solvent. Simultaneous equation develops using 256.8 nm, 236.8 nm and 222.4 nm as the max of paracetamol, phenylephrine hydrochloride and chlorpheniramine maleate respectively. Calibration curves were linear over the concentration ranges of 0-35 μg/mL for all drugs. The results demonstrated that the procedure is accurate, precise and reproducible (relative standard deviation < 1 %), while being simple, cheap and less time consuming, and hence can be suitably applied for simultaneous determination of three drugs in laboratory prepared mixtures and in commercial tablet preparation
