the data set employed in this study was comprised of a number of 6,800 records of lamb’s longevity and their survival rate, collected from 1989 through 2009, from the lori-bakhtiari experimental flock at the shooli station in shahrekord, iran. the data were analyzed using linear models and proportional hazard models with weibull function. these models included fixed factors and direct additive ...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
risk-based assessment methods are commonly used at the contaminated sites by hydrocarbon pollutants. this paper presents the results of a two-dimensional finite volume model of reactive transport of biodegradable btex which have been developed for the saturated zone of an unconfined aquifer in the pump station area of tehran oil refinery, iran. the model governing equations were numerically sol...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
The surface adsorption of heavy metals in effluents with nanoparticles is today asuitable method for effluents treatment. In the present study, lignocellulose nano-fibers(LCNFs) were used as natural adsorbent for lead adsorption. The aim was to evaluate leadadsorption using adsorption isotherms, kinetics and thermodynamics. Fourier TransformInfrared Sp...
ginger waste material (gwm) has been utilized as adsorbent for removal of hazardouspatent blue vf (pbvf) dye from aqueous solution. batch adsorption experiments wereperformed as a function of ph, contact time, dye concentration, adsorbent dose and temperature.the optimum ph required for the maximum adsorption was found to be 2. the experimentalequilibrium adsorption data were tested using langm...
a topical o/w cream containing tretinoin microspheres was prepared. gelatin microspheres of tretinoin were prepared using coacervation method. these microspheres contained about 50% w/w tretinoin. the particle size range of microspheres was between 90-150 m m. in vitro drug release from microspheres and a cream formulation was studied. it was shown that drug release from microspheres followed h...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
the aim of the present work was to assess the feasibility of accononmc8-2ep/nf as a bioadhesive material for developing controlled release gastroretentive microsponges of loratadine. modified emulsion-solvent diffusion method was employed for the preparation of microsponges (f1-f9) based on 32 factorial design. the amount of ethyl cellulose (ec) and polyvinyl alcohol (pva) were selected as inde...
