The macroscopic character of the leaflets ash values extractive values by different solvent extractive behavior on treatment with different chemical reagents fluorescence characters by treatment with different chemical reagents of the powdered leaves of Maoringa oleifera lam (fam moringaceae) were studied to fix some pharmacognostical parameters, chemical group test of different extracts of the...

This study is focused on the removal of leachable lead present in CRT (cathode ray tube) glass employing different chelating agents, NTA (nitrilotriacetic acid) and ATMP (amino trimetilen phosphonic acid), and then on the evaluation of their extractive capability. The operating conditions are the following: T=80°C, t=1h, pH=10, solid/liquid weight ratio=1/10, reagent concentration= 0.1 M. After...

    Given the increasing number of documents, sites, online sources, and the users’ desire to quickly access information, automatic textual summarization has caught the attention of many researchers in this field. Researchers have presented different methods for text summarization as well as a useful summary of those texts including relevant document sentences. This study select...

Bioethanol is among the most promising of biofuels because it has an energy content similar to gasoline while generating lower pollutant emissions than gasoline. But, in order to be used as an automotive fuel mixed with gasoline, ethanol must have less than 0.5 wt % of water. To achieve required ethanol purity, in light of the fact that the ethanol water mixture forms an azeotrope, unconvention...

This paper presents our extractive summarization systems at the update summarization track of TAC 2008. We proposed two novel methods, one is based on the information distance theory, and the other is based on the sentence centrality which derives from the centrality concept in the graph theory. The evaluation results show that the two submitted runs are very competitive to generate extractive ...

This paper reports physicochemical studies in fungal infected galls of Pongamia pinnata. The parameters assayed were Total ash, acid insolubility and water solubility values and extractive values (Alcohol, water and petroleum ether). Fungal infected galls showed significantly higher value of ash, acid insolubility and low water solubility and high extractive values (petroleum ether and water) w...

In this paper, a novel text clustering technique is proposed to summarize text documents. The clustering method, so called ‘Ensemble Clustering Method’, combines both genetic algorithms (GA) and particle swarm optimization (PSO) efficiently and automatically to get the best clustering results. The summarization with this clustering method is to effectively avoid the redundancy in the summarized...

High performance liquid chromatography coupled with photodiode array detector (HPLC-DAD) has been reported to quantify isolated flavonoids or these compounds in complex biological matrices, such as Chinese herbal drugs and products from factories. This work was designed, therefore, to develop an HPLC-DAD system to separate quercetin, luteolin and apigenin and to quantify them in extractive solu...

Today, with rapid growth of the World Wide Web and creation of Internet sites and online text resources, text summarization issue is highly attended by various researchers. Extractive-based text summarization is an important summarization method which is included of selecting the top representative sentences from the input document. When, we are facing into large data volume documents, the extr...
