K.ANUAR, W.H.LIM, W.M.WAN RUSMAWATI, K.DZULKEFLY, M.S.NORSIDAH and S.HAMDAN
Abstract: Ternary phase behavior of sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/Eugenol/H₂O system was constructed at 30.0±0.5°C.  Liquid crystalline and isotropic regions were identified in this system.  Both of these regions decreased with the increased of salinity. At 5M NaCl aqueous solutions, no distinct phases were observed.  Evaporation study on the isotropic region was conducted at different humidity(22% and 85%).  Evaporation rate of the isotropic region increased with the decreased of humidity.  The evaporation rate also increased with the water content.

Trace metal geochemitry and physico-chemical characteristics in the Ibai Estuary, Terengganu, Malaysia
KAMARUZZAMAN B.Y., SHAZILI N.A.M., TAHIR N., HOO E.G. and JAMIL B.T.
Abstract: Dissolved trace metal concentrations (Cu, Mn and Pb) in Surface water were determined in the Ibai estuary during the monsoon and non-monsoon seasons.  Dissolved concentrations for Cu and Pb has average values contamination.  Meanwhile dissolved average Mn of 0.07 ppb which were significantly low are mostly appears to be controlled by the natural processes.  On the whole, trace metal concentrations in the dissolved metals tend to decrease from the mixing zone to the open sea.  Seasonal pattern of temperature, pH and salinity profiles are also presented.  The estuary remained marine dominated during non-monsoon seasons, whereas freshwater dominance prevailed during monsoon seasons.  Based on the salinity distribution, Ibai estuary can be classified as the mixed partially coastal plain estuary.  The temperature of surface and bottom waters are almost uniform or even sometimes they are identical while pH has an inverse relationship with salinity.

Preparation and Characterization of Polypyrrole Polymer Prepared by Non-electrochemical Method
ANUAR KASSIM, ABDUL HALIM ABDULLAH and ZAIDI IDRIS
Abstract: Conductive Polymer polypyrrole was chemically prepared using pyrrole as the monomer and various oxidants such as potassium peroxydisulfate(K₂S₂O₈), ferric(III) chloride(FeCl₃) and ferric(III) nitrate(Fe(NO₃)₃).  The conducting polypyrrole prepared using variable mole ratios of oxidant/pyrrole in aqueous medium showed conductivity between s = 9.80x10^-4 to 7.39x10^-2 S cm^-1.  Changing the solvent in the preparation of polypyrrole using ferric(III) nitrate as an oxidant increased the conductivity.  It was found that methanol solvent gives the highest conductivity at s = 6.619S cm^-1.  It was also found that different type of oxidant and solvent has tremendous influence over the conductivity.  Elemental analysis showed that the ratio of pyrrole to counter ion was found to be in the range of 2 to 7 units for the various oxidants used and stable uP to 413°C.  SEM studies of polypyrrole obtained by using various oxidant and solvent showed this polymer is amorphous and has a granular shape, like beads.  The size of granules depends on the type of oxidants and solvents used.

Comparative scores of Theoretical Mechanistic Biochemistry (TMB) on drug effects : Viagra and Sampatrilat vs. Nisoldipine
DUNSTAN A. K. AKINTONWA
Abstract: Theoretical Mechanistic Biochemistry (TMB) techniques were used to predict from each structure of viagra, nisoldipine and sampatrilat respectively, the biochemical side effect reactions, calcium channel blocker, angiotensin-converting enzyme (ACE) and neutral/endopeptidase (NEP) inhibitor propensities and lipophilic assessment.  Viagra scored negative(-) for (1)notroso, (2)areneimine, (3) epoxide and (4) hydroxyl free radical (*OH).  Sampatrilat was (-) for (1),(2) and (4) but positive (+) for (3).  Nisoldipine was (+) for (1)-(4) respectively.

        For calcium channel blocker chelating propensity, viagra scored (1+), sampatrilat(0) and nisoldipine(4+).  For ACE and NEP inhibitor assessment, viagra scored(0), nisoldipine(1+) and sampatrilat(8+).  For lipophilicity assessment, viagra scored (12+). nisoldpine(10+) and Sampatrilat(8+).  The uniqueness of the TMB lipophilicity of antihypertensive in hypertension and cardiovascular diseases was stressed using nisoldipine vs. enalapril and nifedipine vs. ramipril and nisoldipine vs. sampatrilat.  It was concluded that viagra is in the same class as aspirin for very low calcium blocker.  Nisoldipine is a powerful calcium channel blocker antihypertensive with very low ACE inhibitor potential.  The *OH generated by nisoldipine was concluded to be responsible for the higher incidence of fatal and non fatal myocardial infarction in nisoldipine vs. enalapril and nisoldipine vs. remipril respectively.  Sampatrilat ACE based on >C=0 and O=S=O and for NEP based on -CONH- and SO₂NH- groups reacting with the -CH₂OH of the serine groups of the ACE and NEP enzymes respectively was concluded to very potent with (5+)+(3+) respectively totaling (8+) as a dual inhibitor of the ACE and NEP for the lowering of blood pressure in hypertension target organs.  For lipophilicity and calcium blocker potency : nicardipine (18+) > nimodipine (15+) > nisoldipine (14+) = nifedipine (14+) and for lipophilicity +ACE and NEP inhibitor potency: sampatrilat (16+) > ramipril (14+) > enalapril (11+) are the TMB calcium blockers and ACE inhibitors of choice respectively.

Viagra's TMB potential of (1+) is too low and it is therefore discountenanced as a calcium channel blocker.  Similarly, nisoldipine (1+) for ACE inhibition is very low to be regarded as an ACE inhibitor antihypertensive.

Parent children model using FCM to study dropouts in primary education
W. B. VASANTHA and PRAMODH
Abstract: In this paper we analyze the cause for dropouts in primary education using FCMs.  The major issue of today is the literacy percentage of a nation which in turn boils down to the labelling of the nation as a developed or developing or underdeveloped one.  Unless every one gets atleast the primary education one nation cannot claim it to be even a developing one.  Though the government has brought out many schemes for compulsory primary education still the dropout percentage is very high.  Most of the schemes are difficult to implement and even granted the schemes are implemented still the dropout percentage remains the same.

Stochastic analysis of a system having one Blast Furnace and two rolling machines
S. K. SINGH and V. K. PATHAK
Abstract: This paper deals with the stochastic modeling and configurational analysis of a steel processing system having one blast furnace and two identical rolling machines.  The raw materials that are in the form of blooms are heated up to specific temperature in the blast furnace and afterwards sent to rolling machine which gives them specific shapes of required sizes.  Failure time distribution of the machines are taken to be negative exponential while the repair time and preventive maintenance time distribution are taken to be arbitrary.  Two repairmen, one for blast furnace and other for rolling machines, are used to repair the failed units.  In small scale Industries, most of the works are done manually.  Using regeneration point technique, several measures of the system such as mean time to system failure, point wise availability of the system, expected busy period of the repairman and expected profit earned by the system, are obtained.  At last some graphs are plotted to highlight the results.
