Adsorptive Removal of Furfural from Wastewater on Prepared Activated Carbon from Sawdust
...Show More Authors

Furfural is a toxic aromatic aldehyde that can cause a severe environmental problem especially the wastewater drown from petroleum refinery units. In the present work, a useless by-product from local furniture manufacturing industry; sawdust was used as raw material for the preparation of activated carbon which is chemically activated with phosphoric acid. The effect of adsorption variables which include initial pH of solution (2-9), agitation speed (50-250) rpm, agitation time (15-120) min, initial concentration of furfural (50-250) ppm, and amount of adsorbent material (0.5-2.5) g for the three adsorbents used (prepared activated carbon, commercial activated carbon and raw sawdust) were investigated in a batch process in order to obtain the maximum furfural removal from wastewater. The results obtained from the experimental investigation show that the percentage removal of furfural increases with increasing pH and agitation speed until a maximum value after that it decreased with increasing pH and agitation speed. Also increases with increasing amount of adsorbent material and agitation time until a maximum value then reaches a constant value approximately, and decreasing with increasing furfural concentration. The maximum removal percent of furfural was 97.8, 94.4 and 55.9% for prepared activated carbon, commercial activated carbon, and raw sawdust respectively, which is obtained at a pH of 7.0, agitation speed of 150 revolutions per minute, agitation time of 105 minutes, furfural concentration of 100mg/L, and adsorbent amount of 1.5gm. Langmuir model is best fitted the data than Freundlich model.

Financial education, political instability and firm performance: Evidence from Malaysian SMEs
...Show More Authors

This study assesses the short-term and long-term interactions between firm performance, financial education and political instability in the case of Malaysia Small to Medium Enterprises (SMEs). The simultaneous insertion of financial education and political instability within the study is done intentionally to inspect the effect of these two elements in one equation for the Malaysian economy. Using the bound testing methodology for cointegration and error correction models, advanced within an autoregressive distributed lag (ARDL) framework, we examine whether a long-run equilibrium connection survives between firm performance and the above mentioned independent variables. Using this method, we uncover evidence of a positive long-term link b

Fever is a common illness in the pediatric age group ,the causes could be viral ,bacterial and fungal , this study was focused on bacterial pathogens as gram positive like Staphylococci, coagulase positive or negative ,Streptococci and gram negative like E-coli , Klebsialla ,Proteus, Pseudomonas, Burkhoderia , Acinetobacter and others like Pusturella ,E-alkalescendiaper, Haemophillus influenza and yeast like candida . Four thousand and seventy eight blood samples (4078)were collected in a period between January 2011 and the end of May 2012 at the child welfare hospital ,all the samples were cultured on suitable culture media and then biochemical tests were done using API-E 20 and sugar fermentation tests ,sensitivity

AN ABNORMAL GENITALIA IN CIOJNDELA AULICE DEJ. (COLEOPTERA: CICINDELIDAE) FROM IRAQ
...Show More Authors

Phenomena of an abnormal genitalia was among some specimens of Cicindela aulica Dej.
Collected from Iraq. The fore tarsi of male were asymmetrical having its basal three segments
dilated and clothed beneath with fine bristles as in normal male. While those of the right leg
were found simple as in normal females. Dissection of the genialia of these specimens
showed that they were of two types of both male and female structures.

Gingival tissue samples from periodontitis patients demonstrate epithelial–mesenchymal transition phenotype
...Show More Authors
Abstract<sec><title>Objective

To determine the expression of key epithelial–mesenchymal transition (EMT) markers in gingival tissue samples collected from patients with periodontitis.

Background

Epithelial–mesenchymal transition is a process responsible for shifting epithelial‐phenotype to mesenchymal‐phenotype leading to loss of epithelial‐barrier function. Thus, EMT could be involved as a pathogenic mechanism in periodontitis as both conditions share common promoters and signalling pathways.

Materials and Methods

Gingival tissue samples were collected fro
