EVALUATION OF MASS TRANSFER RATE IN COLUMN OF SMALL LiLSX PARTICLES

Air separation using zeolite based adsorption processes is a widelystudied topic. Proper process modeling is a key requirement to simulate the process. Conventional process modeling for air separation is designed for large scale adsorption processes using a long cycle time. However, advanced technology now permits to use of a short cycle time using small particles, which significantly reduces the size of the process. Traditional process models were mostly developed for large particles (dp > 1.5 mm). Typically, it is safely assumed that intra particle diffusion controls the rate of the process while axial dispersion has a much smaller effect. This is a safe assumption since a long diffusional path exists inside the large particles. The diffusional path inside the small particles (dp> 0.5 mm) is reduced significantly. In addition, smaller particle size increases specific particle surface area which reduces the effect of film resistance. Hence, effect of axial dispersion is more significant for process modeling with small particles. The primary objective of this thesis is to determine the impact of external diffusion to the particles in the process. In this study, breakthrough experiments are utilized to understand the behavior of mass transfer in small
Improving Emulsifying Properties of Egg White Protein by Partial Hydrolysis Combined with Heat Treatment

The present study investigated proteolysis combined with heat treatment to make hen Egg White (EW) an efficient emulsifier. EW was hydrolyzed by protease (Thermoase) at various Enzyme Concentrations (EC) (w/w, 0.1%, 0.2%, 0.4%, 0.8%), followed by heating at 90°C for 8 min. Results showed that optimal emulsifying ability and stability, determined by measurement of emulsion turbidity, were obtained when EC was 0.4%, followed by heat treatment at 90°C. The hydrolysate thus prepared had higher emulsifying ability and stability than either native egg white (nEW) or small molecular weight EW peptides (Runpep), close to the properties of Egg Yolk (EY) which was a reference as a food emulsifier. Surface hydrophobicity (H0) was found to be linearly related to the emulsifying activity and stability of hydrolyzed egg white proteins.
U-Statistic Based Modified Information Criterion for Change Point Problems

The U-statistic based modified information criterion (MIC) is proposed and applied to detect the change point in a sequence of independent random variables. In this article, we show that the method is consistent in selecting the correct model, and the resulting test statistic has a simple limiting distribution. We investigate the method based on both symmetric and anti-symmetric kernel functions. The simulation results indicate that the new method has better power in detecting the changes compared to other methods, such as the likelihood based MIC (Chen et al., 2006) and the Bayesian information criterion of Schwarz (BIC, Schwarz, 1978).
Helium Line Formation and Abundance in a Solar Active Region

An observing campaign (SOHO JOP 139), coordinated between ground-based and Solar and Heliospheric Observatory (SOHO) instruments, has been planned to obtain simultaneous spectroheliograms of the same active region in several spectral lines. The chromospheric lines Ca II K, Hα, and Na I D, as well as He I 10830, 5876, 584, and He II 304 Å lines have been observed. The EUV radiation in the range λ < 500 Å and in the range 260 < λ < 340 Å has also been measured at the same time. These simultaneous observations allow us to build semiempirical models of the chromosphere and low transition region of an active region, taking into account the estimated total number of photoionizing photons impinging on the target active region and their spectral distribution. We obtained a model that matches very well all the observed line profiles, using a standard value for the He abundance ([He] = 0.1) and a modified distribution of microturbulence. For this model we study the influence of the coronal radiation on the computed helium lines. We find that, even in an active region, the incident coronal radiation has a limited effect on the UV He lines, while it is of fundamental importance for the D3 and 10830 Å lines. Finally, we build two more models, assuming values of He abundance [He] = 0.07 and 1.5, only in the region where temperatures are >1 × 104 K. This region, between the chromosphere and transition region, has been indicated as a good candidate for processes that might be responsible for strong variations of [He]. The set of our observables can still be well reproduced in both cases, changing the atmospheric structure mainly in the low transition region. This implies that, to choose between different values of [He], it is necessary to constrain the transition region with different observables, independent of the He lines.
Sediment Quality Analysis and Related Management Approaches in Halifax Harbour [graduate project].

Halifax Harbour is one of the world’s deepest harbours (AMEC Earth & Environmental, 2011). It is sheltered, spacious, and has minimal currents and tides (Robinson, Hui, Soo, & Hellou, 2009). The ice free port leaves the harbour accessible year round, and it is the closest port of call for ships operating the North Atlantic, Round-the-World and Suez routes (AMEC Earth & Environmental, 2011). These advantageous natural conditions have made Halifax Harbour one of the largest commercial ports in Canada and home of Canada’s east coast Navy. In addition to being a major shipping port, industrial centre, naval centre and research centre, Halifax Harbour is surrounded by one of the fastest growing urban regions in Atlantic Canada (Chairpefkon, Thirumurthi, Parker, & Griffiths, 1993). Increasingly, the Harbour’s ecosystems have been placed under stress as a result of intensive human activities along its shorelines. Since the colonization of the area 250 years ago, Halifax Harbour has been a receptacle for raw sewage and industrial wastes (Federico & Henderson, 2001). Environmental assessments show that acute chemical components in the water and sediments still have great potential hazards to the health of human and biota (AMEC Earth & Environmental, 2011). Harbour sediments have historically tended to be hotspots of contamination due to direct and indirect cause related to anthropogenic activities developed in the area such as shipping-related activities, industries, presence of highly populated areas, rivers and other discharges. Dredging and disposal processes can release pollutants bound to contaminated sediments and make them available to the biota.
Microsatellite DNA-based genetic traceability of two populations of splendid alfonsino, Beryx splendens (Actinopterygii: Beryciformes: Berycidae)—Project CELFISH—Part 2

Background. The study is a contribution to Project CELFISH which involves genetic identifi cation of populations of fi sh species presenting a particular economic importance or having a potential to be used in the so-called commercial substitutions. The EU fi sh trade has been showing a distinct trend of more and more fi sh species previously unknown to consumers being placed on the market. Molecular assays have become the only way with which to verify the reliability of exporters. This paper is aimed at pinpointing genetic markers with which to label and differentiate between two populations of splendid alfonsino, Beryx splendens Lowe, 1834, a species highly attractive to consumers in Asia and Oceania due to the meat taste and low fat content. Material and methods. DNA was isolated from fragments of fi ns collected at local markets in Japan (MJ) (n = 10) and New Zealand (MNZ) (n = 18). The rhodopsin gene (RH1) fragment and 16 microsatellite DNA fragments (SSR) were analysed in all the individuals. The sequences obtained were processed using the BioEdit and BLAST software, whereas SSR data were processed with the GeAlEX analysis package. Results. The BioEdit software-aided comparison of MJ and MNZ nucleotide sequences of the rhodopsin gene fragments were identical and showed 100% agreement with the alfonsino sequence deposited under access number DQ197832. The preliminary analysis of SSR markers showed all the loci analysed in both populations to be polymorphic, and when randomly selected specimens were assigned to the original populations. The affi nity test correctly identifi ed the provenance of all those specimens. Conclusion. The results obtained constitute a tool for molecular differentiation between alfonsino populations collected in the FAO 81 (New Zealand) and FAO 71 (Japan) areas for the purpose of catch quota control and for checking the agreement between the label declaration and the actual product.
Numerical Study of Detonation Instability for a Two-Step Kinetics Model

The stability of CJ detonations has been investigated numerically with a two-step kinetics model. The reaction model consists of a non-heat release induction step, followed by an exothermic step. Both steps are governed by the Arrhenius kinetics model. The e ect of activation energies associated with these steps on the detonation front behavior has been studied. This study was arranged in two stages. At each stage, one of the activation energies was kept constant and the other one was changed. In the steady detonation structure, the activation energies of the rst and second steps (Ea1; Ea2) control the induction and reaction lengths, respectively. Increasing Ea1 (for a xed Ea2) increases induction length and destabilizes a detonation, the same behavior as a one-step model. Increasing Ea2 rst increases reaction length and has a stabilizing e ect (i.e., the amplitude of oscillation decreases). Further increasing Ea2 has a destabilizing e ect. The present study shows that the ratio of the reaction length to the induction length characterizes general features of detonation stability.
Lifecycle Cost Analysis of Internally Cured Jointed Plain Concrete Pavement

Internal curing is a technique that has been developed to prolong cement hydration by providing internal water reservoirs in a concrete mixture that do not adversely affect the concrete mixture’s fresh or hardened physical properties. Internal curing grew out of the need for more durable structural concretes that were resistant to shrinkage cracking. This report covers an investigation into the relative costs and benefits of internal curing using a lifecycle cost analysis (LCCA) that compares internally cured (IC) jointed plain concrete pavement to conventionally cured (CC) pavement. This analysis was based on a pavement designed for use in Dubuque, Iowa. According to the analysis, IC concrete makes it possible to design pavement with decreased thickness or increased joint spacing or to reduce the required maintenance over the analysis period, which results in savings in initial construction cost. Even if the thickness does not change, IC pavement requires less maintenance than a comparable CC pavement to provide satisfactory performance over its service life. However, the initial construction cost of IC pavement is about 3.2% higher than that of CC pavement with the same thickness. Considering all of the evidence, the net present value of IC pavement is less than that of CC pavement.
Electrode configuration and electrical dissipation of mechanical energy in quartz crystal resonators

Mechanical resonators made with monolithic piezoelectric quartz crystals are promising for studying new physical phenomena. High mechanical quality factors (Q) exhibited by the mm-sized quartz resonators make them ideal for studying weak couplings or long timescales in the quantum regime. However, energy losses through mechanical supports pose a serious limiting factor for obtaining high quality factors. Here we investigate how the Q of quartz resonators at deep cryogenic temperatures can be limited by several types of losses related to anchoring. We first introduce means to reduce the mechanical losses by more than an order of magnitude in a no-clamping scheme, obtaining Q-factors of 108 of the lowest shear mode. We can exclude a wide coverage of aluminum metalization on the disk or bond wires as sources of dissipation. However, we find a dramatic reduction of the Q-factor accompanying an electrode configuration that involves strong focusing of the vibrations in the disk center. We propose a circuit model that accounts for the reduced mechanical Q-factor in terms of electrical losses. In particular, we show how the limiting factor for losses can be small ohmic dissipation in a grounding connection, which can be interpreted as electrical anchor losses of the mechanical device.
Reducing Deviant Behavior through Workplace Spirituality and Job Satisfaction

Despite the growing number of studies on workplace spirituality, there is still lack of studies that have explored the relationships between workplace spirituality, job attitudes and behaviors. The purpose of this paper is to propose a model on the relationship between workplace spirituality and workplace deviant behaviour with job satisfaction as a mediator. Workplace spirituality is expected to correlate negatively with workplace deviant behaviour and positively with job satisfaction, and job satisfaction is expected to correlate negatively with workplace deviant behaviour. Drawing from social control theory, social exchange theory and previous literature, we hypothesize that job satisfaction mediates the relationship between workplace spirituality and workplace deviant behaviour. According to this proposed model, an employee who experienced workplace spirituality is more likely to be satisfied with work and will not engage in workplace deviant behaviour. Given the potential effect of workplace spirituality on workplace deviant behaviour via job satisfaction, there is a need for organizations to create a culture of spirituality at the workplace.
Job Satisfaction of Educationists : An important Antecedent for Enhancing Service Quality in Education Sector of Pakistan

Enhancement in employee service quality has drawn an unprecedented and unparalleled attention of researchers and mangers over last couple of decades. The importance of service quality is further augmented and amplified when it comes to education sector and more specifically, the Higher Education Sector of Pakistan. Nonetheless the role of job satisfaction of an employee can never be undermined or diluted in the process. The current study has therefore, been carried out with the intention to gauge the role of job satisfaction in increasing the service quality of University Teachers. To empirically validate the claims, a total sample of 206 respondents was taken using convenient sampling technique from the faculty members of different Public and Private Sector universities. Analysis of the study revealed a positive and significant relationship between job satisfaction and teaching quality thus making it clear the imperative and vital role of Job satisfaction in ensuring the Enhanced Service Quality of employees in Higher Education Sector of Pakistan.

Investors’ Attention and Stock Market Volatility∗

Investors’ attention to the stock market is time-varying and strongly co-moves with stock market volatility. We build a theoretical model consistent with this observation. Our model features fluctuating attention to news, and implies a quadratic relationship between investors’ attention and stock market volatility. We find empirical support for this relationship. Volatility and risk premium are counter-cyclical, and the relationship between them changes with the level of attention. Furthermore, the short-term asset—the claim to dividends in the near future—is volatile and commands a large equity premium during downturns, in line with recent empirical findings. ∗We would like to thank Bernard Dumas and Julien Hugonnier for stimulating conversations and many insightful comments. We would also like to acknowledge comments from Tony Berrada, Jerome Detemple, Christian Dorion, Alexandre Jeanneret, Semyon Malamud, Michael Rockinger, and seminar participants at the Mathematical Finance Days Conference in Montréal and the Princeton-Lausanne Workshop on Quantitative Finance in Lausanne.

Development of Hemosomal Drug Delivery System

Haem is found in all living cells as well tissues in the form of proteins such as cytochromes, hemoglobin’s and peroxides. This is act as catalyst for the formation of oxygen radicals. Encapsulation of haem or hemoglobin with in lipid vesicles or liposome’s is called “Hemosomes” or it is also called Liposomeencapsulated hemoglobin (LEH). Which are 0.1 to 10 microns in dimension, and it is a technology of preparing artificial red blood substitutes. The synthetic cells are stable being somewhat smaller and stronger than normal red blood cells and are having same electrophoretic movements. Hemoglobin (Hb) encapsulation within a liposome is one of the strategies in the development of artificial oxygen carriers. The review article includes preparation techniques, characterization and stability of Hemosomal drug delivery system.
Redox-active polyimide–polyether block copolymers as electrode materials for lithium batteries

Redox-active polyimide–polyether multi-block copolymers were synthesized by polycondensation reaction of aromatic dianhydrides with α-ω-diamino poly(ethylene oxide). Polyimide-b-polyether block copolymers showed microphase separation between a hard-polyimide domain and a soft-polyether domain as observed by Atomic Force Microscopy. The block copolymers were investigated as cathodes for polymer/lithium metal batteries. Polymer cathodes were formulated where the block copolymer had a dual role as active material and binder, with a small amount of carbon black (15 wt%). Naphthalene polyimides showed higher discharge voltages, higher specific capacities as well as better cycling performance, compared to pyromellitic polyimides. The longest PEO blocks resulted in a better performance as electrodes. The best performing naphthalene polyimide-b-PEO2000 presented an excellent value of discharge capacity of 170 mA h g−1, stable after 100 cycles at a current density of 1Li+/5 h and considering the polyimide as the active material. The average discharge plateaus were 2.51 V and 2.37 V vs. Li+/Li.

Rice growth and its indices for nutrient uptake from soils of Muda Irrigation Scheme

Soil columns (each one cubic meter) of eight soil series from Muda Irrigation Scheme were used to study the growth and nutrient uptake of direct-seeded MR 84 rice variety. Rice growth was determined by soil fertility status, which was classified as low, intermediate and high fertility as based on yield. Low soil fertility regardless of soil series affected rice crop growth significantly ( p <0.05). The variability in soil fertility status produced rice yield in the range of 3.8‐16 t/ha with a mean of 8.8 t/ha. The cumulative biomass accumulation over the growing period (105 days) resembled the sigmoid growth curve. The period of rapid growth lasted for about 4‐6 days between 60‐68 DAS, 59‐64 DAS and 57‐61 DAS for the low, intermediate and high-yielding crop respectively. Their respective maximum growth rates were 24.4, 42.7 and 52.7 g/m 2 /day. During the period of rapid growth, the high-yielding crop displayed SPAD values of Y-leaf in the range of 39‐ 40. Nutrient composition between high and low crop yield indicated significant variation in nutrient imbalance ( p <0.05). Hindrance to the achievement of high yield was due to the deficiency of Mg, P, Ca, S, Mn and Zn. The proportions of element taken up among nutrients of primer (N:P:K), secondary (Mg:Ca:S) and micro (Fe:Mn:Zn:Cu) throughout the entire growth period were 5.0:1.0:9.7; 1.2:1.0:1.5; and 48:46:27:1 respectively. The values of the important DRIS norms (N/S, N/K and Fe/Mn) at 60 DAS for high-yielding MR 84, were 10.6, 0.46 and 1.13 respectively. The concentration of N, P, K, Ca, Mg, S, Fe, Mn, Zn and Cu in leaf at harvest were 1.58%, 0.21%, 2.95%, 0.64%, 0.24%, 0.16%, 131.65 ppm, 95.20 ppm, 27.56 ppm and 1.04 ppm, respectively for the crop that achieved yield greater than 10 t/ha. The total nutrient uptake, the quantity of nutrient removed by the grain, the mineral requirement indices and the harvest indices for the respective nutrients were also identified.
Open64-based Regular Stencil Shape Recognition in HERCULES

This paper discusses our design and implementation of a recognizer of stencil-like accesses in the Open64 compiler. This is a reference implementation in a real production compiler and serves as an example for supporting stencils on other compilers. We have developed the recognizer as part of our greater HERCULES framework which extends the Open64 compiler with user-level formulation of analysis and transformations. Our user base, which comprises computational scientists utilize this capability for identifying kernels that may benefit from a nested domain decomposition parallelizing scheme.
Finite element modeling of corneal strip extensometry

Corneal biomechanical properties are an important element in the study of corneal biomechanics. There are currently two techniques to obtain these properties; an inflation test and the strip extensiometry test. As the inflation test has been numerically modelled in several studies, this study focusses on accurately modelling the strip extensiometry test. Two methods were considered to simulate the experimental conditions namely, a single phase and a two phase method. A finite element model of the corneal strip specimen was developed using an elastic fibre reinforced constitutive model to describe the corneal microstructure. The experimental conditions were simulated by defining prescribed displacements to simulate the required phases for each method. The results indicated that by using the two phase method, which is a more accurate description of the experimental setup, that no additional post processing is required to obtain a reaction force response which correlates with experimental data.
