Abstract
Mississippi Power Company's Victor J Daniel, Jr. electric generating facility is hosting a United States Department of Energy (USDOE)-sponsored CO2 sequestration demonstration as part of the Southeast Carbon Sequestration Regional Partnership. The goal of the project is to demonstrate safe and secure CO2 storage in a deep saline reservoir. Prior to well drilling and injection operations, the primary focus of the project was on public acceptance and permitting of such activities. Three permits were required for the project, a USDOE-NEPA environmental questionnaire, a Mississippi Oil and Gas Board (MOGB) drilling permit, and a Mississippi Department of Environmental Quality (MDEQ) underground injection control (UIC) permit.
The injection well was permitted under the Environmental Protection Agency's Class V Experimental Technology guidelines through the Mississippi Department of Environmental Quality; however, the well was constructed to Class I (non-hazardous) standards. To our knowledge, this is the first CO2 storage well permitted to Class I standards in the United States and certainly the first in the State of Mississippi. This paper will detail the permitting activities for this demonstration project.
Risk Comparison of Alternative Fuels

Published: March 2009

Abstract
The purpose of this paper is to identify and assess risks related to alternative fuels, and relate those risks to public health and life cycle questions. Using the school bus fleet of the Chicago Public Schools as a model, this paper compares the environmental health and safety impact of current diesel fuel usage with that of increased use of alternative technologies and fuels.
Four alternative fuels have been studied: Low sulfur diesel (baseline), biodiesel (BD20), ethanol-diesel blends (ED10), and compressed natural gas (CNG) from renewable feedstocks. Impact was assessed utilizing the GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) 1.7 Well to Wheel model.
Analytical approximate solutions for two-dimensional viscous flow through expanding or contracting gaps with permeable walls
Authors: Dinarvand Saeed , Rashidi Mohammad , Doosthoseini Ahmad 
Published: March 2009

Abstract
In this paper, the problem of laminar, isothermal, incompressible and viscous flow in a rectangular domain bounded by two moving porous walls, which enable the fluid to enter or exit during successive expansions or contractions is solved analytically by using the homotopy analysis method (HAM). Graphical results are presented to investigate the influence of the nondimensional wall dilation rate α and permeation Reynolds number Re on the velocity, normal pressure distribution and wall shear stress. The obtained solutions, in comparison with the numerical solutions, demonstrate remarkable accuracy. The present problem for slowly expanding or contracting walls with weak permeability is a simple model for the transport of biological fluids through contracting or expanding vessels.

Published: March 2009

Abstract
Ultrathin silicon dioxide (SiO2) layers formed on Si substrate with nitric acid have been investigated using both acoustic deep-level transient spectroscopy (A-DLTS) and electrical methods to characterize the interface states. The set of SiO2/Si structures formed in different conditions (reaction time, concentrations of nitric acid (HNO3), and SiO2 thickness [3â€“9 nm]) was prepared. The leakage current density was decreased by post-oxidation annealing (POA) treatment at 250Â°C in pure nitrogen for 1 h and/or post-metallization annealing (PMA) treatment at 250Â°C in a hydrogen atmosphere for 1 h. All structures of the set, except electrical investigation, current-voltage (I - V), and capacitance â€” voltage (C - V) measurements, were investigated using A-DLTS to find both the interface states distribution and the role of POA and/or PMA treatment on the interface-state occurrence and distribution. The evident decreases of interface states and shift of their activation energies in the structures with PMA treatment in comparison with POA treatment were observed in most of the investigated structures. The results are analyzed and discussed.

AbstractWe demonstrate the 3% mol ytterbium doped phosphate glass air-clad photonic crystal fibre (PCF) laser of 43-cm length in single-mode operation. The fabrication and testing of the laser is introduced. The laser has the diameter of the core of 12 µm created in photonic microstructure and generates at wavelength of 1030 nm. Near 4-W output power and 14.6% slope efficiency against the launched pump power is demonstrated in preliminary characterization. The difference of refractive indices achieved in doped and undoped glass is Δn = 0.0004. We used the doped glass with the negative core-cladding Δn to assure the photonic crystal fibre way of single-mode propagation.

Effects of fields and anchoring on biaxial nematic ordering
Authors: Yasen M. , Torikai M. , Yamashita M. 
Published: March 2009

AbstractSymmetry of a nematic liquid crystal phase is broken by an anchoring wall and also by an external field. Nematic system sandwiched between biaxial anchoring walls is introduced as a correspondent to a bulk nematic system exposed to a couple of fields, an electric field and a magnetic one in directions perpendicular to each other, and thermal behaviours of the system are studied. The crossover between a homeotropic structure and homogeneous one occurs, similarly to the bulk system in the fields, in which the anchoring condition of coexistence is shown to have the same expression as the one at the bulk. As to a characteristic phenomenon at the sandwiched system, it is proved that an appearance of a biaxial nematic order suppresses a uniaxial nematic order. A surface transition, i.e., a wetting phenomenon is shown to occur also in the biaxial nematics, even though the uniaxial order is suppressed therein.
Effect of bias in ferroelectric-antiferroelectric relaxation

Published: March 2009

AbstractThe ferroelectric-antiferroelectric transition in greyscale generation of antiferroelectric liquid crystal displays (AFLC) is a heterogeneous process. The process has been described as the growth of finger-like domains [1]. We have previously studied the ferroelectric-antiferroelectric phase transition, relaxation that follows the data pulse in surface stabilized asymmetric antiferroelectric liquid crystal displays using biasless video frequency waveforms [2]. This relaxation involves an intensity decay of the light transmitted by a pixel and depends on several parameters such as surface stabilization, rotational viscosity of the AFLC, magnitude of the data pulse, and bias voltage.The usual multiplexed driving of AFLC displays leads to long-term stabilisation of the grey levels induced by the data pulses within the selection time. However, depending on the bias level, alternative greyscale mechanisms may be obtained by allowing the grey levels to decay during the frametime. These greyscales may be advantageous in some instances since they improve the dynamic response of the AFLC device and reduce the reset time of the waveform.In this study we extend the previous work to include the effect of bias. We present the measured data, in terms of growth pattern and speed and present an extension of the previously model on order to explain the results.

Formulation development of oral controlled release tablets of hydralazine: Optimization of drug release and bioadhesive characteristicsThe current study involves development of oral bioadhesive hydrophilic matrices of hydralazine hydrochloride, and optimization of theirin vitrodrug release profile andex vivobioadhesion against porcine gastric mucosa. A 32central composite design was employed to systematically optimize the drug delivery formulations containing two polymers,viz., carbomer and hydroxypropyl methyl cellulose. Response surface plots were drawn and optimum formulations were selected by brute force searches. Validation of the formulation optimization study indicated a very high degree of prognostic ability. The study successfully undertook the development of an optimized once-a-day formulation of hydralazine with excellent bioadhesive and controlled release characteristics.

Estimation of the Energy Security Level and Definition of the Criteria for Damage Forecasts
In the work, the energy security indicators in a region (a state) are considered, and two general directions are proposed for search among the criteria for estimation and forecast of the damage inflicted by power supply limitations: based on the differentiated calculations for each economic subject, and on the generalised indices of regional economy. Of especial interest is analysis of a recently introduced damage intensity factor and its dependence on the level of limitations and the type of energy carriers.

Authors: Hossain A , Kabir G , Ud-deen MM , Alam AMS 
Published: March 2009

The present investigation was undertaken in order to study the somatic karyotypes of four species of Nymphaea available in Bangladesh. Karyotypes of four species of Nymphaea revealed that most of the chromosomes were metacentric indicating their primitive nature and chromosome counts revealed a polyploid series of tetraploid, pentaploid and hexaploid based on X=14. Findings of the present study indicated that Nymphaea pubescens is a hexaploid (6X=84, white flower) which might have originated by chromosome doubling of Nymphaea daubeniana (3X=42) while Nymphaea rubra and Nymphaea nouchali (Type-1) are tetraploid (4X=56) species.

Impacts of Food Diversity on some Reproductive Attributes in the Gray Field Slug <i>Deroceras reticulatum</i> (MÃ¼ller)
Authors: Islam M Saiful 
Published: March 2009

Using a food choice design consisting of a single, double and multiple diets, impacts of three common vegetables viz. cabbage (CAB), lettuce (LET) and potato (POT) on some important reproductive attributes of the gray field slug Deroceras reticulatum (MÃ¼ller) have been assessed. Although adult body weight was not affected by the diets, brood size was maximum in a double diet (CAB+POT), but multiple diets (CAB+LET+POT) did not enhance egg productivity. Both LET and POT had induced significantly greater number of eggs per day in comparison with CAB. Multiple diets resulted in significantly heavier eggs than the eggs from single or double diet regimes. Eggs laid on LET had the lowest and that on CAB+LET+POT had the highest developmental time but the hatch rate across the diet regimes did not differ significantly. Hatchlings from the single diet treatment were heavier than the double diet regime, but those between single vs. multiple or double vs. multiple diets did not vary statistically. The heaviest hatchlings were from LET and the lightest ones were from the CAB+LET treatments. The present results would help researchers in selecting a convenient culture medium for rearing experimental slugs in the laboratory. In addition, the data suggest that polyculture of vegetables might reduce slug damage, especially by reducing the brood size, egg production and hatchling size of D. reticulatum in the fields.

Authors: Islam MZ , Begum S , Ara H , Waliullah TM 
Published: March 2009

The study was carried out to determine the effects of pesticide on the growth and nitrogen fixation by blue green algae (BGA) that isolated from three different soils of Bangladesh viz., saline soil, calcareous soil and red soil. Furadan 5G, one of the most commonly used pesticides was selected for the study of eighteen taxa of blue green algae (BGA) which brought under the unialgal culture in the selected soil types. Variations observed in growth and nitrogen fixation among the isolates of a particular type of soil. The culture resulted as BGA grow slow under heterotrophically grown cultures than that of autotrophically grown cultures. On the other hand, nitrogen fixation in heterotrophically grown cultures was observed at higher rate. However satisfactory result was observed in both cases when field dose of Furadan was applied practically. In this case, heterotrophically grown cultures were more tolerant to pesticides with respect to growth and nitrogen fixation. Key words: Blue green algae, Furadan, nitrogen fixation, heterotrophic growth, autotrophic growth. Â doi: 10.3329/jbs.v15i0.2199 J. bio-sci. 15: 23-34, 2007

Authors: Rahman MH , Alsadon AA 
Published: March 2009

The present study was aimed to compare the photoautotrophic (PAM) and photomixotrophic micropropagation (PMM) of three potato cultivars (Hermes, Rosetta and Asterix). Cultures were initiated from single node explants and established in MS basal medium with some modifications. Potato plantlets responded in sugar-free media although sugar-containing media (PMM1 and PMM2) performed better as compared to that of sugar-free (PAM1 and PAM2) media. The PMM1 produced shoot length averaging 6.25 cm with 8.08 nodes and weighing 0.24 g fresh weight of plantlet. On the other hand, PAM1 grown culture produced 4.03 cm shoot length, 8 nodes and 0.06 g of fresh weight. Shoot length and fresh weight of plantlets were significantly higher in PMM1 and PMM2 based media. Whereas the number of nodes per shoot was not significantly different on media with or without sugar (except the media PAM2). Sugar and vitamin-free media ( PAM2 ) performed inferior in all the traits. Key words: Potato, Photoautotrophic and Photomixotrophic Micropropagation.

Surface Modification of Polymers
Authors: Kang E.T. , Neoh K.G. 
Published: March 2009

Abstract
Many applications require polymeric materials to be in contact with other materials or with specific environments. In this respect, the surface and interface properties of polymers cannot be overemphasized. This article describes, reviews, and updates the three most common surface modification techniques for synthetic polymers, viz, (i) plasma modification, (ii) surface grafting and graft polymerization, and (iii) chemical modification and reaction. Plasma modification involves surface energetic interactions, as well as plasma polymerization and deposition. Surface modification via grafting and graft polymerization generally involves the “grafting to” and “grafting from” approaches. The latter approach has been made even more versatile by the development of surface‐initiated controlled radical polymerizations in the late 1990s. Chemical modification of polymer surfaces includes ozone treatment, chemical and electrochemical redox reactions, sulfonation and halogenation, photochemical reactions, biologically influenced modification, and layer‐by‐layer coating. Finally, the effects of physical structures of modified surfaces are briefly discussed.
“Click” Chemistry in Macromolecular Synthesis
Authors: Binder Wolfgang H. , Zirbs Ronald 
Published: March 2009

Abstract
“Click” chemistry is a valuable tool in polymer science for the efficient linkage of functional entities, oligomers or polymers, yielding access to functional homo‐, block‐, star‐, graft‐polymers as well as higher polymeric architectures (dendrimers, hyperbranched polymers, supramolecular polymers, gels, polymer brushes). Besides other efficient “click” reactions, the copper‐(I)‐catalyzed 1,3‐dipolar‐azide/alkyne cycloaddition reaction has emerged as the method of choice to this and related purposes. Main advantage in relation to conventional linking reactions are (1) quantitative yields, (2) mild reaction conditions, (3) solvent and substrate insensitivity, and (4) high yielding reactions under both homogeneous and heterogeneous reaction conditions. The article describes basics of the reaction as well as applications in polymer science and technology.

The influence of heightened body‐awareness on walking through apertures
Authors: Lopresti‐Goodman Stacy , Kallen Rachel W. , Richardson Michael J. , Marsh Kerry L. , Johnston Lucy 
Published: March 2009

AbstractThe reported study measured the ratio between aperture‐width and hip‐width that marked the critical transition from frontal walking to body rotation for male and female participants. Half of the participants of each sex wore form‐fitting lycra clothes and half loose‐fitting jogging suits. Participants wearing the form‐fitting clothing reported heightened body awareness relative to those wearing the loose‐fitting clothing. For male participants this difference was reflected in a smaller aperture‐to‐hip ratio in the form‐fitting than loose‐fitting clothing condition. That is, males walked frontally through smaller apertures when wearing form‐fitting than when wearing loose‐fitting clothing. For females there was no difference in walking action as a function of clothing style. Results are discussed in terms of the perception of action opportunities in the environment, the influence of body awareness on such perception and sex differences.

Expert testimony in recovered memory trials: Effects on mock jurors' opinions, deliberations and verdicts
Authors: Buck Julie A. , Warren Amye R. 
Published: March 2009

AbstractThe current study examined the impact of adversarial expert testimony on deliberations and verdicts in a mock trial involving recovered memories of child sexual abuse. Participants (N = 238) were randomly assigned to one of the six conditions in a 2 (Defense Expert: absent or present) × 3 (Plaintiff Expert: absent, general or specific/therapist) factorial design. After reading the mock trial transcript, participants completed a questionnaire and deliberated to reach a jury verdict. The defense expert's statements effectively reduced the number of pro‐plaintiff verdicts and the plaintiff's credibility. These effects were not mitigated by the plaintiff experts, suggesting that the plaintiff experts may only confirm jurors' prior pro‐repression beliefs. Copyright © 2009 John Wiley & Sons, Ltd.
