The paper is to lay special emphasis on study to design new management system into current information management in order to expand a method such as a library management information system. Studying data resources on hand and a new system model for information service management have been formed and realized, and at the same time problems of the hidden dangers of data redundancy get solved. The new system is called as a post-information management and the current system called as a pre-information management system. Whole information management system (IMS) consists of two systems, PrIMS and PoIMS. PoIMS is main foundations of statistics and analysis data. We offer a post-information management system which focuses on design system at data statistics and analysis with formulas. It is applied the retrieval combined models under multi-restrictive conditions and theories to the lending book rates in a library with PoIMS.

This paper reviews the importance of physical urban form and urban design in directing citizens’ behavioral patterns. It is of great interest for new urbanism theoreticians. Due to growing internal travels in the cities, their environmental repercussions, reaching stable travel patterns and travel demands’ management, urban design tools can be used in the neighborhoods of the city. previous studies in this focus on the key roles of residential density, professional density, accessibility, physical design of the neighbourhood, and etc. Neighbourhood design in dense form with mixed applications and visual and space quality for walking can be effective in reducing car travels and the amount of crossed distance by the citizens. The extent to which physical design of the neighbourhood and urban design affects citizens’ behavioral patterns is the concern of this paper.

Drying seeds and maintaining low seed moisture content is critical in hot and humid climatic conditions. In this study Zeolite beads which are inert adsorbent materials have been used for drying tomato and onion seeds. Response Surface Methodology was employed to optimize the parameters of drying in central composite experimental design. The seeds of tomato cv. Pusa Ruby and onion cv. Nasik Dark Red with initial moisture content of 8.6 to 15.4% dry weight basis (d.b.), were dried at five levels of residence time (1.3, 4, 8, 12, 14.7 h) and five levels of seed bead ratio (1:0.33, 1:0.5, 1:0.75, 1:1, 1:1.17). Second degree polynomial models were found significant for each response viz. germinability, vigour and final moisture content. The optimum values of process variables was found to be 1:0.5, 10.8 hours and 11.84 %, seed bead ratio, residence time and initial moisture content, respectively in case of tomato seed. Seed bead ratio, residence time and initial moisture content of 1:0.62, 6.52 and 13.62, respectively were found optimum for onion seed.

Spiders belong to the group of arthropods, they are found in the terrestrial habitat. Spider venoms are an incredible source of biologically active substances which selectively target a variety of vital physiological functions in both insects and mammals. Venom of spiders are heterogeneous not only between the species but also within the species. They are made up of complex mixtures of biologically active enzymatic and non enzymatic components. Many toxins isolated from spider venom have been valuable in helping to determine the role diversity of neuronal ion channels and the process of exocytosis.

Easier access to botanicals and the return to traditional means of pest control have cast a new spell on botanicals. Botanicals are cheap, efficient and not prone to induce resistance in the pest. Among the studied botanicals used as pesticides worldwide, the neem tree and the tobacco plant have proved to be the richest in active compounds and are some of the potent sources of natural biocides. Bioassays were carried out on the gall wasp Leptocybe invasa on Eucalyptus grandis using neem, tobacco and neem/tobacco mixture each at concentrations of 5, 10 and 15g/l and observations on oviposition, gall development and adult emergence were made at two week intervals for a period of 12 weeks. Results showed that tobacco had the highest insecticidal effects in reducing oviposition rate, whilst the mixture of neem/tobacco reduced gall formation. Neem was potent at reducing adult emergence and for all extracts, an increase in concentration led to a decrease in oviposition, gall formation and adult emergence. Results from this study point to the feasibility of using these extracts in the control of L. invasa on Eucalyptus from the devastation of this pest.

A novel and selective method for the fast determination of trace amounts of Co(II)ions in water samples has been developed.  The first organic-solution-processable functionalized-Multiwalled carbon nanotubes (MWNTs) (SPFMWNTs) hybrid material with porphyrins. porphyrin–Multiwalled carbon nanotubes (MWNTs)  nanohybrid, 5-4 (aminophenyl)-10, 15, 20-triphenyl porphyrin and its photophysical properties including optical (TPP) and grapheme oxide molecules covalently bonded together via an amide bond (TPP-NHCO- SPFMWNTs )were used as absorbent for extraction of Co(II)   ions by solid phase extraction method. The complexes were eluted with HNO₃ (2M)10% V.V^-1 mthanol in acetone and determined the analyte by flame atomic absorption spectrometry.  The procedure is based on the selective formation of Co(II)  at optimum pH by elution with organic eluents and determination by flame atomic absorption spectrometry.The method is based on complex formation on the surface of the ENVI-18 DISK^TM disks modified porphyrin–Multiwalled carbon nanotubes (MWNTs)  nanohybrid, 5-4 (aminophenyl)-10, 15, 20-triphenyl porphyrin (TPP) and grapheme oxide molecules covalently bonded together via an amide bond (TPP-NHCO- SPFMWNTs ) followed by stripping of the retained species by minimum amounts of appropriate organic solvents. The elution is efficient and quantitative. The effect of potential interfering ions, pH, TPP-NHCO- SPFMWNTs, amount, stripping solvent, and sample flow rate were also investigated. Under the optimal experimental conditions, the break-through volume was found to about 1000mL providing a preconcentration factor of 600. The maximum capacity of the disks was found to be 568± 3 µg for Co²⁺. The limit of detection of the proposed method is 5ng per 1000mL.The method was applied to the extraction and recovery of Co in different water samples.

This study was designed to determine the predictors of literacy skills among Chinese preschoolers. There were 136 preschoolers aged ranged between three to six years old with their parents and teachers recruited in this study using a Multi-Stage Cluster sampling technique. Home-based learning activities were measured using Home Learning Environment Questionnaire (Lonigan & Farver, 2002). Meanwhile, children’s literacy skills were respectively assessed using Test of Early Reading Ability Third Edition (Reid, Hresko, & Hammill, 2001). This study found that preschoolers with higher level of literacy skills were came from families who practiced more home-based learning activities, and have highly educated parents and high family monthly income. Besides that, findings revealed that older children perform high level of literacy skills. The findings of this study imply that home learning was the most significant unique predictor of child’s literacy skills within all tested variables.

Groundwater management, particularly in arid regions, should be viewed holistically and linked to the sustainable management of the ecosystem. Only through consideration of the interaction between the groundwater and other environmental components can it be possible to elaborate a long-term program for rational groundwater use and protection. Ancient methods of groundwater management, such as the qanats system, provide an excellent demonstration of human ingenuity to cope with water scarcity. To make a qanat, one needs a source of water, which may be a real well, but can also be an underground reservoir (e.g., a cave with a lake) or a water-bearing geological layer, which can be recognized as a damp area in an otherwise arid region. When one has identified this source, a tunnel is cut to the farm or village that needs the water. Shafts are added for three reasons: as air supply, to remove sand and dirt, and to prevent the tunnels from becoming dangerously long. The shafts are not very far apart, and as a result, a qanat seen from the air gives the impression of a long, straight line of holes in the ground - as if the land has been subjected to a bombing run. Typically, the qanat becomes a ditch near its destination; in other words, the water is brought to the surface by leading it out of the slope. In fact, one creates an artificial artesian well and an oasis. There are about 22000 qanats in Iran with 274000 kilometers of underground conduits all built by manual labor. The amount of water of the usable qanats of Iran produce is altogether 750 to 1000 cubic meter per second. Qanats have been an ancient, sustainable system facilitating the harvesting of water for centuries in Iran, and more than 35 additional countries of the world such as India, Arabia, Egypt, North Africa, Spain and even to New world.

The success of every organization is highly dependent on how it attracts recruits, motivates and retains its quality workforce. In the current scenario, the organizations need to be more proactive to ensure the development of their workforce and commitment. Hence the organizations necessitate adopting the strategy to improve the employee’s Quality of Work Life (QWL) to satisfy both organizational objectives and employee needs. Quality of work life is the degree to which work in an organization contributes to material & psychological well-being of its members. The present study attempts to measure the level of level of perceived quality of work life among the employees of private manufacturing companies in the state of Tamilnadu, India. An attempt is also made to find out if the quality of work life has any significant relationship with job related variables and with demographic variables. The work related factors are combined in nine categories: Adequate & Fair, Compensation, Safe & Healthy Working Condition, Opportunity for Development, Opportunity for Growth & Security, Social Integration, Constitutionalism, Work & Total Life Space, Social Relevance & Working Life, Quality of Work Life Feelings and Overall Quality of Work Life.

In the present study, the FT-IR and FT-Raman spectra of 6-amino-2,3-dihydro-1,4-phthalazinedione (ADHPD) have been recorded in the region 4000-400 cm-1 and 3500-50 cm-1, respectively. The fundamental modes of vibrational frequencies of ADHPD are assigned. Theoretical information on the optimized geometry, harmonic vibrational frequencies, infrared and Raman intensities were obtained by means of Hartree-Fock (HF) and density functional theory (DFT) gradient calculations with complete relaxation in the potential energy surface using 6-311+G(d,p) basis set. The vibrational frequencies which were determined experimentally from the spectral data are compared with those obtained theoretically from ab intio HF and DFT/B3LYP calculations. A close agreement was achieved between the observed and calculated frequencies by refinement of the scale factors. The predicted first hyperpolarizability also shows that the molecule might have a reasonably good non-linear optical (NLO) behaviour. 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).
