title: Caste Oligarchy in Sindh: Structure and Function

description: Caste lies at the root of politics both in India and Pakistan. While in the Indian case, it has lately been identified by Dalit activists and brought it into political debates there, in Pakistan talking caste politics is still a social taboo. Almost all major Indian political parties, including BJP, Congress and Communist party, play caste politics under different hoods. Whereas in case of India it manifests itself in the form of Brahmin-Bania nexus, in Sindh its Mulla-feudal nexus as far as parliamentary politics is concerned, and Sammat Sindhi and upper caste Hindu nexus as far Sindhi nationalist politics is concerned. In case of Dalits of Sindh specifically, however, its Sindhi-Bania order that dominates from pre-partition times with the gradual increase in the political power of Shah\Syed castes. In Pakistan, and particularly in case of Sindh, Brahmin is displaced by Syed/Shah, and Bania by an upper caste feudal-capitalist. Bania which in local jargon is called Vaniyo (Businessman) continues to dominate Hindu-minority politics in the name of oppressed religious minority and an oppressed minority within the oppressed Sindhi nation. As the Brahmin domination of India began with the formation of first democratic government in India with Jawhar Lal Nehru, the Brahmin becoming the first Prime-Minister of India, similarly in Sindh domination of Syed or Shah and Pir, the Muslim counterpart of Brahmin began gradually from 1947 with the migration of Hindu Sindhis to India under the newly acquired religious legitimacy as the most sacred, and the most deserved ruling caste of Sindh. Sindh is proverbially called the land of Sufis, and Syed is unquestionably believed as the noblest caste. (Further read in the attachment)

title: Separation and preconcentration of metal ions from water using anion-exchange resin loaded with piperazinedithiocarbamate

description: The anion exchange resin was successfully loaded with piperazinedithio- carbamate via anion exchange mechanism. The new synthesized complexing resin was characterized by IR spectroscopy. The loading capacity of complexing ligand onto resin at pH 5 during loading times of 8 min was found to be 3.5 µmol g-1. The separation of the metal ions as Ag(I), Cu(II), Pb(II) and Au(III) was studied in batch method. The optimum pHs for the sorption of Ag(I) and Cu(II) were found to be 7 and 2, respectively. The optimum pH of Pb(II) and and Au(III) of 5 was obtained. The suitable contact time of Ag(I) and Pb(II) were found to be at 15 and 20 min, respectively. While Cu(II) and Au(III) showed long sorption kinetic within 60 min. The sorption behaviors of all metal ions fit well to the Langmuir’s model and the sorption capacities in the order of Pb(II) &gt; Ag(I) &gt; Cu(II) &gt; Au(III) were observed with the maximum sorption capacities of 81.1, 74.2, 43.5 and 21.9 µmol g-1, respectively. For the flow system, the separation and preconcentration of Ag(I) and Pb(II) were studied. The optimum sample flow rates of Ag(I) and Pb(II) were obtained at 3.0 and 4.0 mL min-1, respectively. The elution of Ag(I) was achieved by using 5.0 mL of 0.5 mol L-1 thiourea in 1 mol L-1 HCl at the flow rate of 0.25 mL min-1 and the Pb(II) was desorbed by 5.0 mL of 0.2 mol L-1 EDTA in 0.1 mol L-1 HCl at the flow rate of 1.0 mL min-1. The preconcentration factor of 10 and 50 for Ag(I) and Pb(II) were obtained, respectively. Coexisting cations such as Na+, K+ and Ca2+ did not affect the recoveries of metal ions in comparison with cation exchange resin. The proposed method can be applied to preconcentrate Ag(I) and Pb(II) from tap water and sea water with spiked sample method before determination of Ag(I) and Pb(II) with FAAS resulting in high accuracy and precision.

title: Charged nanoparticles from poly(vinyl alcohol) derivatives

description: Negatively charged polymers, poly(vinyl alcohol-co-vinyl butane sultone) and poly(vinyl alcohol-co-vinyl dodecane-co-vinyl butane sultone), and positively charged polymers, poly(vinyl alcohol-co-vinyl diethylamino butanate) and poly(vinyl alcohol-co-vinyl diethylamino butane), were synthesized by grafting poly(vinyl alcohol) with 1,4-butane sultone and dodecyl moieties or diethylamino butane and dodecyl moieties through appropriate substation reaction. Polymer with various sultane, dodecyl, diethylamino butane substation degree were prepared. The negatively charged polymers were able to self-assemble into particles upon changing solvent from dimethyl sulfoxide to water. It was found that the degree of substitution of sultone groups and dodecyl moieties on PVA vackvone affected the particle size. The size of poly(vinyl alcohol-co-vinyl butane sultone) particles increased as the sultone substitution increased while that of poly (vinyl alcohol-co-vinyl dodecane-co-vinykl butane sultone) particles decreased as the sultone substitution increased. In contrast, none of the positively charged polymers obtained could self-assemble into any specific architecture. Encapsulate 2-ethylhexyl p-methoxycinnamate (EHMC) into the prepared particles were demonstrated and theie release profiles were investigated.

title: Economic evaluation of ceftazidime and meropenem for the treatment of severe melioidosis, Northeastern Region in Thaland

description: This economic evaluation aims to determine the incremental cost-effectiveness of meropenem if used instead of ceftazidime in treatment of severe melioidosis from the perspective of regional hospitals in Thailand. A modelling-based cost-effectiveness analysis was performed based on a published randomised controlled trial conducted in Sapprasitprasong Hospital. A decision tree was used to represent the course of melioidosis treatment. Two major costs incurred to the hospital were included in the analysis; hospitalization cost and drug cost. The result is expressed as cost per incremental life year saved. To ensure the reliability of study results, extensive sensitivity analyses were used to handle uncertainties in model parameters. Results from this preliminary study suggest that the incremental cost for treatment with meropenem instead of ceftazidime is 31,000 Baht. Meropenem increases life years by 0.34 years compared to ceftazidime. Meropenem is not a dominant choice of treatment because it provides higher effectiveness but with higher cost of treatment; the incremental cost effectiveness is 90,338 Baht per one additional life year saved. One way sensitivity analysis showed the result was highly sensitive to probability of death within 48 hours and death rates after treatment failure. Probabilistic sensitivity analysis suggested that although the baseline result suggests that meropenem is more cost-effective as the ICER is lower than the WTP threshold of 100,000 Baht, there is a high probability that this conclusion might be wrong due to the uncertainty in many parameter estimates. Therefore, it is inconclusive that meropenem should be adopted to replace the standard treatment from this analysis. There is an ongoing randomised controlled trial comparing the effectiveness of ceftazidime and meropenem; when the trial result is available this analysis will be repeated for more robust results.

title: Characterization and functional analysis of prophenoloxidase system-associated genes from the black tiger shrimp penaeus monodon / Walaiporn Charoensapsri

description: The prophenoloxidase (proPO) activating system plays an essential role in the immune defence against microbial infections in many invertebrates. In the present study, two PPAE genes (designated PmPPAE1 and PmPPAE2) and a novel proPO (PmproPO2) gene were identified from hemocytes of the black tiger shrimp, Penaeus monodon. Sequence analysis revealed that PmPPAE1 exhibited the highest amino acid sequence similarity of 70% to a PPAE of the freshwater crayfish Pacifastacus leniusculus, whilst PmPPAE2 showed 51% amino acid sequence similarity to the insect Manduca sexta PAP1. Analysis of the PmproPO2 sequences showed that PmproPO2 shared a 67% sequence identity to the PmproPO1. Tissue expression analysis revealed that PmPPAE1, PmPPAE2, PmproPO1 and PmproPO2 mRNA transcripts were mainly expressed in hemocytes. Analysis of their larval developmental gene expression revealed that PmPPAE1 and PmproPO2 transcripts were expressed in all larval stages (nauplius, protozoea, mysis and post-larvae), whereas PmPPAE2 and PmproPO1 transcripts were mainly expressed in the late stages of larval development (mysis and post-larvae). Double-stranded RNA(dsRNA)-mediated gene suppression of PmPPAE1and PmPPAE2 resulted in a significant reduction in the respective transcript levels and resulted in a significant decreased in total PO activity in the PmPPAE1 (37%) and PmPPAE2 (41%) knockdown shrimps as compared with saline injected group. Experimental infection of PmPPAE knockdown shrimps with the highly pathogenic bacterium Vibrio harveyi significantly increased the cumulative mortality and the number of bacterial colonies in the silenced shrimps. These results indicate that PmPPAE1 and PmPPAE2 participate in the proPO system and also play an important role in the shrimp immune defence against V. harveyi infection. Gene silencing of PmproPO1 and PmproPO2 by RNA interference (RNAi) resulted in a significant decrease in the respective endogenous proPO mRNA levels in hemocytes and a reduction of total PO activity by 75 and 73%, respectively. Experimental infection of P. monodon with the V. harveyi revealed that the PmproPO silenced shrimps were more susceptible to bacterial infection than the control GFP dsRNA and saline injected shrimps, suggesting that the two proPOs are important components in the shrimp immune system and play the crucial role in the defence against V. harveyi infection. In addition, the mature protein of PmPPAE1 was expressed in Escherichia coli and insect cell expression system, but the obtained recombinant proteins were not stable. The SP domain of PmPPAE1 was expressed in E. coli system. The recombinant SP domain of PmPPAE1 was used as an immunogen to generate the antibody against SP domain of PmPPAE1 and western blot analysis demonstrated that the endogenous PmPPAE1 was found only in hemocytes but not in cell-free plasma of P. monodon.

title: Oxidative stability of omega-3 fatty acid emulsions coted with polyelectrolyte multilayer

description: In this study, we demonstrated the first preparation procedure for oil-in-water emulsion coated with tertiary and quaternary polyelectrolyte layers and their improvement on the oxidation and creaming stability of omega-3 oil-in-water emulsions. Based on the study of the optimum preparation condition, primary emulsions were prepared by homogenizing a solution of 5 %w tuna oil and 95 %w of 1.5 %w casein in water at pH 6 for 2 minutes at 20,000 rpm and 5 homogenization cycles. Surface modification of the primary emulsion by polyelectrolytes was achieved by using the layer-by-layer self assembly technique. First, the primary emulsions were further coated with either poly(diallyl dimethyl ammonium chloride) PDADMAC or chitosan (polycationic) called secondary emulsion. Then, the tertiary emulsions were prepared by coating secondary emulsion with alginate (polyanonic). Last, the quaternary emulsion coated with casein-PDADMAC-alginate-PDADMAC could be synthesized. The equivalent point for multilayer emulsion preparation was investigated by measuring %transmission and zeta potential. The mass ratios of the emulsion to polyelectrolyte at the equivalent points for the preparation of secondary emulsion were 3.2 and 3.0 for casein-PDADMAC and casein-chitosan, respectively. The mass ratios for tertiary emulsions coated with casein-PDADMAC-alginate, casein-chitosan-alginate and quaternary emulsion coated with casein-PDADMAC-alginate-PDADMAC preparations were 0.24, 0.33 and 0.77, respectively. Oxidative stability of the omega-3 in tuna oil-in-water emulsions was measured by using UV-Vis spectroscopy via ferric thiocyanate method. Physical and oxidative stability of the multilayer emulsions were found to be improved when compared with primary emulsions. The oxidative stability of all multilayer emulsions were increased around 36-38% over primary emulsion at day 4 and 5 of storage. This is because the thicker layer of multilayer emulsions and the cationic charge on the droplet of secondary and quaternary emulsion can prevent the droplet from the oxidants. The creaming stability of secondary, tertiary and quaternary emulsion was also increased around 29.78, 45.70 and 65.38% compared to the primary casein emulsion at day 7 of storage

title: Method development for the determination of sulfonamides using a monolithic column coupled with amperometric detection

description: Sulfonamides (SAs) were electrochemically investigated at boron-doped diamond (BDD) electrode using cyclic voltammetry. Comparison experiments were carried out using glassy carbon (GC) electrodes. It was found that the BDD electrode provided well-resolved oxidative irreversible cyclic voltammograms and higher current signals when compared to GC electrode. Thus, BDD electrode was used to optimize conditions for the HPLC-EC system. The proposed method was improved by reducing the analysis time using a monolithic column coupled with amperometric detection to determine 7 sulfonamides (sulfaguanidine, sulfadiazine, sulfamethazine, sulfamonomethoxine, sulfamethoxazole, sulfadimethoxine and sulfaquinoxaline). Because of its rapid separation, low back-pressure and high separation efficiency compared to a particle-packed column, a monolithic column (100 mm x 4.6 mm) was used for sulfonamide separation. Chromatographic separation was performed in less than 8 min at flow rate of 1.5 mL min-1. The optimal detection potential using hydrodynamic voltammetry was found to be 1.2 V versus Ag/AgCl. The method was applied to determine sulfonamides in shrimp. The recoveries of sulfonamides in spiked shrimp samples at 1.5, 5 and 10 μg g-1 were in the range of 81.7 % to 97.5 % with a relative standard deviation (R.S.D) between 1.0 % and 4.6 %. This methodology produced results that were highly correlated with HPLC-MS data. Therefore, the proposed method can be used for the rapid, selective and sensitive evaluation of sulfonamides in contaminated food.

title: Perfection of glued graphs of perfect original graphs

description: A graph G is perfect if the chromatic number and the clique number have the same value for every of its induced subgraph. A glued graph results from combining two vertex-disjoint graphs by identifying nontrivial connected isomorphic subgraphs of both graphs. Such subgraphs are referred to as the clones. The two vertex-disjoint graphs are referred to the original graphs. The main results involve in the perfection of glued graphs whose original graphs are perfect. We find necessary and/or sufficient conditions for the perfections of glued graphs. We also study the chromatic number and the clique numbers of glued graphs in terms of these parameters of their original graphs. Only some specified clones and original graphs are investigated:- clones such as induced subgraphs of both original graphs and complete graphs; original graphs such as bipartite graphs, complete graphs and forests.

title: Facilitating factors and barriers for intention to accept HPV vaccine among young females in Hanoi - Viet Nam

description: The objectives of the study were to assess facilitating factors and barriers for intention to get HPV vaccine among 15-25 years old females in Hanoi, Vietnam based on Health Belief Model framework. This research study was a cross-sectional research. Simple random sampling and cluster random sampling were used to select the participants. Overall, 386 young female agreed to answer the questionnaire. Data were collected by using constructed questionnaire and analyzed by percentage, mean, standard deviation, the independent t-test, chi-square test and logistic regression model. The results showed that young Vietnamese female had insufficient knowledge on HPV (80%) and HPV vaccine (58%). The predictors for intention to accept HPV vaccine among young female in Vietnam are knowledge on HPV vaccine (OR= 1.97, CI: 1.16-3.33), perceived benefit (OR= 3.08., CI: 1.45-6.54), perceived barriers (OR=0.314., CI: 0.13-0.75) and health care provider’s consultation (OR= 4.24., CI: 1.917-9.41). The facilitating factors which encourage young females use HPV vaccine in future are their demands to protect their health from cervical cancer and genital warts, their belief of the effectiveness of HPV vaccine. On the other hand, barriers towards their intention to get HPV vaccine include lacking of information related to HPV and HPV vaccine, being afraid of vaccine’s side effect and the cost of the vaccine. This study’s recommendations include organizing broader and more intense educational programs about knowledge on HPV and HPV vaccine to all the people, especially for those who are at the recommended age to use the vaccine. In addition, the study recommends to adopt health policies which partly finance the HPV vaccination to reducing the out-of pocket cost of the vaccine for young women and to encourage them to get vaccination.

title: Ownership structure and dividend policy of Thai firms

description: This paper investigates into the role of dividend in controlling agnecy between large and small shareholders and getween managers and sahreholders. Data includes 1,341 samples of listed firma in the Stock Exchange of Thailand during 2002 to 200/8. Thailand has high concentration of ownership and there may be two groups of firms. One with agency conflict between large controlling shareholder and other shateholders and one between managers and shareholders. The empirical findings suggest there are two groups of firm. Results provide evidence of rent extraction by controlling shareholder. The second largest and other shareholder are not effective in moitoring the largest. Among firms with no controlling shareholder, the largest shareholder has been effective in monitoring the management. Share concentration by the second largest does not help improve the effictiveness of monitoring. Monitoring is both statistically and economically significant.

title: Synthesis of soil soluble triarylmethane and formazan dyes

description: In this research, a series of triarylmethane dyes was synthesized by a condensation reaction of N,N-diethylaniline with various aromatic aldehydes. Effects of the aromatic aldehyde on the dye formation, solubility and photophysical behavior of the triarylmethane compounds were investigated. Most of triarylmethane dyes have good solubility property in organic solvent. The resulting triarylmethane dyes had green color. The selected triarylmethane dye 10 exhibited high solubility in gasoline and common organic solvents. The triarylmethane dye 10 at a concentration of 12,000 ppm was found to be stable in gasoline for at least 3 months. A series of formazan dyes was synthesized by a condensation reaction of cardanol with phenylhydrazine compounds, then coupling these products with diazonium salts of various aromatic amines. Effect of the solubility and photophysical behavior of the formazan compounds were investigated. In most cases, cardanol in the dye molecules was proved to be advantageous in giving dyes with satisfactory solubility in fuel. The resulting formazan dyes had yellow and orange color.

title: Gumbling behavior in Thai stock market

description: This dissertation investigates inventor's gambling begavior in the Thai stock market during sample period between January 1999 and December 2008, This study is motivated by the ancedotal evidence of prevalent lottery participation, gambling activity and evidence of behavioral bias in trading decisions. Using serveral measures of investor trading activity, we find that retail investors exhibit stronger preference in lottery-like stocks (low priced stocks with high idiosyncratic volatility and skewness) than institutional and foreign investors do and their propensity to invest in lottery-like stock increases during the economic recession which is similar to demand in lotter tickets and other gambling activities. Our evidences show that retail investor gambling-motivated decision negatively influences their portfolio performance. Our analyses on the gambling seasonality indicate that retail investors demand more of lottery-like stocks in June while institutional investors demand more lof lottery-like stocks in December. Foreign investors do not exhibit any difference in demand level for lottery-like stocks during different time periods. Our findings from GJR-GARCH model display the significantly positive return of lottery-like stocks in Junes and Decembers. As evidences by our bivariate vector autoregression analysis, positive lotter-like stock returns seasonality in June is corresponding with retail investors' demand of lottery-like stock in June and returns seasonality in December is corresponding with institutional investors' demand of lottery-like stocks in December. This gambling effect provides new insight into the conventional anomalous seasonality in stock return, the gambling seasonaliity.
