Preparation of poly (MAA)‐crosslinked pregelled starch graft copolymer and its application in waste water treatments (2009)

Abstract Propelled starch (PG) was first crosslinked with epichlorohydrin to obtain insoluble crosslinked pregelled starch (CPS). The latter was graft copolymerized with different amounts of Methacrylic acid using potassium persulphate as initiator. This was done to obtain six levels of poly (MAA)‐crosslinked pregelled starch graft copolymers (PMCPS) having different graft yields (expressed as meq COOH/100 g starch) with increasing order and designated as (PMCPS 1 to PMCPS 6). The latter copolymers were dispersed in aqueous solution of heavy metal ions (Cu 2+ , Pb 2+ , Cd 2+ , and Hg 2+ ) and filtered to form polymer‐metal ions complex. Different factors affecting the heavy metal ions removal such as pH, extent of grafting, treatment time and starch dose were studied in detail. It was found from the obtained results that; the residual metal ions removal from their aqueous solutions increased with (a) increasing the extent of grafting of PMCPS i.e., from PMCPS 1 to PMCPS 6; (b) Increasing the pH of the metal ions solution complex from 1 to 8; (c) increasing the starch dosage from 0.25 to 2.0% (W/V), then leveled off thereafter, (d) increasing the time of the reaction up to 20 min then leveled off after that. On the other hand, Pb, Cd and Hg ions were also removed from their solutions with different extent. Furthermore, the prepared copolymer could be recovered by washing the metal ions from the complex with weak acid 1 N HNO 3 (pH 2) and the metal‐binding activity of the starch was slightly reduced by this process. Finally, the ability of PMCPS to remove three types of basic dyes from their solutions was also reported. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Addiction history moderates the effect of prefrontal 10-Hz transcranial alternating current stimulation on habitual action selection (2020)

Individuals with substance use disorders (SUDs) transition more quickly from goal-directed to habitual action-selection, but the neural mechanisms underlying this phenomenon remain unclear. Data from animal models suggest that drugs of abuse can modify the neurocircuits that regulate action-selection, enhancing circuits that drive inflexible, habit-based stimulus-response (S-R) action-selection and weakening circuits that drive flexible, goal-directed actions. Here, we tested the effect of bilateral 10-Hz transcranial alternating current stimulation (10Ηz-tACs) of the dorsolateral prefrontal cortex on action-selection in men and women with a SUD history and an age- and sex-matched control group. We tested the hypothesis that true 10Ηz-tACS versus active sham stimulation would reduce perseverative errors after changed response contingencies for well-learned S-R associations, reflecting reduced habit-based action-selection, specifically in the SUD group. We found that 10 Hz-tACS increased perseverative errors in the control group, but in the SUD group, 10 Hz-tACS effects on perseverative errors depended on substance abuse duration: a longer addiction history was associated with a greater reduction of perseverative errors. These results suggest that 10Ηz-tACs altered circuit level dynamics regulating behavioral flexibility, and provide a foundation for future studies to test stimulation site, frequency, and timing specificity. Moreover, these data suggest that chronic substance abuse is associated with altered circuit dynamics that are ameliorated by 10Ηz-tACs. Determining the generalizability of these effects and their duration merits investigation as a direction for novel therapeutic interventions. These findings are timely based on growing interest in transcranial stimulation methods for treating SUDs.<b>NEW & NOTEWORTHY</b> Treating the executive dysfunction associated with addiction is hampered by redundancies in pharmacological regulation of different behavioral control circuits. Thus, nonpharmacological interventions hold promise for addiction treatment. Here, we show that, among people with an addiction history, 10-Hz transcranial alternating current stimulation (10Hz-tACS) of the dorsolateral prefrontal cortex can reduce habitual actions. The fact that 10Hz-tACS can regulate behavioral flexibility suggests its possible utility in reducing harmful habitual actions.
Competitive Lotka-Volterra Population Dynamics with Jumps (2011)

This paper considers competitive Lotka-Volterra population dynamics with jumps. The contributions of this paper are as follows. (a) We show stochastic differential equation (SDE) with jumps associated with the model has a unique global positive solution; (b) We discuss the uniform boundedness of $p$th moment with $p&gt;0$ and reveal the sample Lyapunov exponents; (c) Using a variation-of-constants formula for a class of SDEs with jumps, we provide explicit solution for 1-dimensional competitive Lotka-Volterra population dynamics with jumps, and investigate the sample Lyapunov exponent for each component and the extinction of our $n$-dimensional model.

Binary quantization using Belief Propagation with decimation over factor graphs of LDGM codes (2007)

We propose a new algorithm for binary quantization based on the Belief Propagation algorithm with decimation over factor graphs of Low Density Generator Matrix (LDGM) codes. This algorithm, which we call Bias Propagation (BiP), can be considered as a special case of the Survey Propagation algorithm proposed for binary quantization by Wainwright et al. [8]. It achieves the same near-optimal rate-distortion performance with a substantially simpler framework and 10-100 times faster implementation. We thus challenge the widespread belief that binary quantization based on sparse linear codes cannot be solved by simple Belief Propagation algorithms. Finally, we give examples of suitably irregular LDGM codes that work with the BiP algorithm and show their performance.
Potent inhibitory effects of benzyl and p-xylidine-bis dithiocarbamate sodium salts on activities of mushroom tyrosinase (2010)

A novel monofunctional benzyldithiocarbamate, C6H5CH2NHCSSNa (I), and a bifunctional p-xylidine-bis(dithiocarbamate), NaSSCNHCH2C6H4CH2NHCSSNa (II), as sodium salts, were synthesized by reaction between p-xylylenediamine or benzylamine with CS2 in the presence of NaOH. They were characterized by spectroscopic techniques such as 1H NMR, IR, and elemental analysis. These water-soluble compounds were examined for their inhibition of both activities of mushroom tyrosinase (MT) from a commercial source of Agricus bisporus. l-3,4- Dihydroxyphenylalanine (L-DOPA) and l-tyrosine were used as natural substrates for the catecholase and cresolase enzyme reactions, respectively. Kinetic studies showed noncompetitive inhibition of I and mixed type inhibition of II on both activities of MT. The inhibition constant (KI) of II was smaller than that of I. Raising the temperature from 27 to 37°C caused a decrease in KI values of I and an increase in values of II. The binding process for inhibition of I was only entropy driven, which means that the predominant interaction in the active site of the enzyme is hydrophobic; meanwhile, the electrostatic interaction can be important for the inhibition of II due to the enthalpy driven binding process. Fluorescence studies showed a decrease of emission intensity without a shift of emission maximum in the presence of different concentrations of compounds. An extrinsic fluorescence study did not show any considerable change of the tertiary structure of MT. Probably, the conformation of inhibitor-bound MT is stable and inflexible compared with uninhibited MT.
Thermally Stable Bulk Heterojunction Solar Cells Based on Cross-Linkable Acrylate-Functionalized Polythiophene Diblock Copolymers (2013)

We report on the synthesis of new thermally cross-linkable all-conjugated diblock copolymers composed of a poly(3-hexylthiophene) (P3HT) block and an acrylate-functionalized polythiophene block. These copolymers are then used in bulk heterojunction (BHJ) solar cells with [6,6]-phenyl C61-butyric acid methyl ester (PCBM), and their photovoltaic performances are compared with standard P3HT/PCBM devices. Thermal cross-linking of the functional copolymers/PCBM blends is performed to improve the thermal stability of the active layer. BHJ photovoltaic cells with cross-linkable copolymers and PCBM show initial power conversion efficiencies slightly lower than that of P3HT devices. However, solar cells with cross-linkable copolymers retain more than 85% of their initial power efficiency value after 165 h of thermal annealing (accelerated aging test), whereas the same devices with P3HT retain less than 65% of their initial power efficiency. This improvement of the thermal stability of BHJ photovoltaic cells is the result of the polymer network that hampers PCBM diffusion and phase separation, as confirmed with TEM and AFM analysis of the microscopic morphology. Such an improvement is mostly observed when using a cross-linkable P3HT with a short spacer between the acrylate group and the polythiophene backbone.
Black phosphorus as a new lubricant (2018)

In recent years, a new 2D-layered material—black phosphorus (BP)—has been a rising star after the era of graphene owing to its high charge carrier mobility, tunable direct bandgap and unique in-plane anisotropic structure. With the development of the synthesis and modification methods of BP, its extensive applications, e.g., transistors, batteries and optoelectronics have emerged. In order to explore its full potential, research into the tribological properties of BP 2D-layered materials such as lubrication additives and fillers in self-lubricating composite materials would be not only of high scientific value but also of practical significance. In this work, recent advances on the friction and lubrication properties of BP nanosheets made by our group, including the micro-friction properties, the lubrication properties of BP nanosheets as water-based and oil-based lubrication additives, and the friction and wear of BP/PVDF composites will be presented. Finally, the future challenges and opportunities in the use of BP materials as lubricants will be discussed.
The Resistivity Property of Nikel Loaded Winter Wheat Straw Char (2010)

In this paper, the effects of nickel ions concentration (4.0 wt%, 4.5 wt%, 5.0 wt%), carbonization temperature (700°C, 800°C, 900°C), heating rate (5°C/min, 15°C/min, 20°C/min) and particle size (0.1-0.2 mm, 0.2-0.3 mm, 0.3-0.38 mm) on resistivity of char derived from winter wheat straw were studied. The result showed that when nickel loading is 5.0 wt%, carbonization temperature is 900°C, heat rate is 5°C/min and particle size is 0.2-0.3 mm, the resistivity is lower and its value is 1.5 ¿·cm.
Electro-Thermal Behaviour of Large Size Li-Ion Batteries from End of Life EV Module (2019)

Li-ion batteries (LiBs) reach the end of life (EOL) in electric vehicles (EV) application when their capacity reaches 80% of nominal value. However, there is plenty of energy and power remaining in them, which can be used in second-life applications. The suitability of EOL EVbatteries for second-life applications needs to be carefully investigated. For instance, the state of charge (SOC), state of health (SOH), and thermal behaviour during ageing need to be accurately assessed before implementation in the second-life application, otherwise, the<br/>second-life system performance would suffer. Moreover, the variation of voltage and current density during cycling lead to a non-uniform temperature distribution, degradation and imbalanced ageing. A clear understanding of these degradations is also essential to achieve the full potential of EOL EV-batteries in the second-life applications.<br/>In this study, the electro-thermal behaviour of EOL Nissan Leaf battery pack is investigated. Four EOL batteries (LMO chemistry and an initial capacity of 33Ah) from the same Nissan Leaf battery module are used in this study. Batteries arrangement in the module is shown in Fig. 1 (a) and to establish the connection in the module, tabs were cut and their active connection width was 1/4 of full tab width.
Meaning Making Model: Inner purpose, Goals, and Religiosity/Spirituality Partially Predict Acceptance Strategies and Volunteerism Behaviours (2014)

The present study aimed to evaluate the influence of global meaning on volunteerism behaviours and on acceptance strategies in response to unchangeable life events. The study is based on the meaning making model proposed by Park (2010). A total of 348 participants completed the survey; ages ranging from 18 to more than 70 years. Vignettes were used as an approach to evaluate the meaning-making model. The present study was a correlational survey design. The predictor variables were global meaning as measured by purpose in life, goals, and R/S experiences, beliefs and practices. The dependent variables were volunteerism behaviours and acceptance style of responses to unchangeable life situations depicted in vignettes. The questionnaire was presented as an online survey. The results supported most of the hypotheses, confirming the relevance of Park's meaning making model and the validity of the proposed measures. The present study is but a small step in understanding and finding empirical support for the meaning making model (Park, 2010). The results suggest that from a foundation of strong purpose in life, intrinsic goals, and religiosity/spirituality, one is in a better position to grow from negative life events. Together with volunteerism that encourages one to have an outward looking perspective in life, values in oneself could be developed and reinforced, further strengthening one's abilities to face negative events in life.
In situ microdialysis of prostaglandins in adipose tissue: stimulation of prostacyclin release by angiotensin II. (1994)

In order to clarify the physiological roles that PGE2 and PGI2, the two major metabolites of arachidonic acid in adipose tissue could play in vivo, their measurements have been undertaken in the interstitial fluid of rat periepididymal adipose tissue using in situ microdialysis. This technique appears suitable with a rather high dialysis yield (70%) for the measurement of prostaglandins. The basal equilibrium extracellular concentrations of 6-keto-PGF1 alpha (the stable metabolite of PGI2) and PGE2 can be estimated to 1 and 0.3 nM, respectively. Experiments designed to study the hormonal regulation of in situ PGI2 and PGE2 production show that (i) lipolysis induced by local perfusion of 10(-6) M isoproterenol is not accompanied by an increase of either 6-keto-PGF1 alpha or PGE2 in the dialysate but, in contrast (ii) perfusion of angiotensin II (10(-7)-10(-5) M) leads, independently of triacylglycerol hydrolysis, to a transient dose-dependent and indomethacin-sensitive increase of released 6-keto-PGF1 alpha with no change in released PGE2. Therefore, in vivo PGI2 appears as the major hormonally regulated prostaglandin in rat adipose tissue, and angiotensin II appears as a physiological effector of its extracellular release.

Nuclear Matrix Proteins and Their Potential Applications to Diagnostic Pathology (1999)

The nuclear matrix is the nonchromatin scaffolding of the cell nucleus that confers nuclear shape, organizes the nuclear chromatin, and regulates many important intranuclear biochemical events. Although our understanding of the nuclear matrix and its proteins is still evolving, it is clear that nuclear matrix proteins (NMPs) hold considerable promise as diagnostic tools for pathologists. Early evidence suggests that NMPs may be useful biomarkers of neoplastic disease in serum, body fluids, and tissues. NMPs are also potential candidates for use as tumor prognostic factors and targets of anticancer drugs. Moreover, NMPs may hold the key to understanding important cellular events, such as neoplastic transformation, steroid hormone binding, and apoptosis. Despite impressive gains made by cellular biologists and biochemists toward understanding the structure and function of the nuclear matrix, many of the potential applications of NMPs to diagnostic pathology are largely unexplored. Thus, NMPs should prove an exciting and fruitful area of investigation for experimental and clinical pathologists who are interested in developing diagnostic tests for detecting, quantitating, and characterizing these proteins in human tissues and body fluids and translating these applications into the clinical pathology laboratory.
Novel Similarity-Invariant Line Descriptor and Matching Algorithm for Global Motion Estimation (2014)

We present a new and fast line descriptor and matching algorithm to geometrically register video frames that are deformed by a similarity transformation and contain line segments but with very low texture details, such as navigation maps. Line segments are extracted from the frames, and each line is described with a novel line descriptor that does not depend on pixel intensities. The described lines are then matched together and the matches are input to an outlier removal algorithm in order to estimate the parameters of the transformation describing the global motion between the frames. We propose a method for fast parameter estimation of the transformation using line segments instead of points. Additionally, we apply this algorithm in the testing and error detection context of navigation systems, in which we show how to detect map jump artifacts that could occur during the development of these systems, leading to a jerky and unsmooth motion between the frames. The proposed descriptor and its matching algorithm are shown to be fast enough for online use and very robust against a wide range of translation, rotation, and scale changes. Furthermore, the error detection algorithm allows to detect almost all map jump artifacts while maintaining a very low number of false alarms.
Knowledge-based genetic algorithm for layer assignment (2001)

Layer assignment is an important post-layout optimization technique in Very Large Scale Integrated-circuit (VLSI) layout automation. It re-assigns wire segments in a routing solution to appropriate layers to achieve certain optimization objectives. This paper focuses on investigating the layer assignment problem with application to via minimization, which is known to be NP-complete. In this paper a knowledge-based genetic algorithm for the layer assignment problem is proposed, with the aim of utilizing domain-specific knowledge to speedup the process of evolution and to improve the quality of solutions. Experimental results show that this knowledge-based genetic algorithm can consistently produce the same or better results than a heuristic algorithm and a traditional genetic algorithm.

Effects of therapeutic paracentesis on systemic and hepatic hemodynamics and on renal and hormonal function (1987)

Thirteen patients with cirrhosis and tense ascites (six with and seven without peripheral edema) underwent 4- to 15-liter paracentesis without intravenous "colloid" replacement. Cardiac output increased from 6.6 +/- 0.7 liters per min at baseline to 8.2 +/- 0.7 liters per min (p less than 0.003) 1 hr after large-volume paracentesis completion and fell to 7.5 +/- 0.69 liters per min (p less than 0.05 vs. baseline, p less than 0.02 vs. 1 hr) 24 hr after large-volume paracentesis completion. There was no change in mean arterial pressure or mean pulmonary artery pressure. Central venous pressure fell from 9.1 +/- 0.8 mm Hg at baseline to 8.6 +/- 1.4 mm Hg 1 hr post-large-volume paracentesis to 6.8 +/- 1.0 mm Hg (p less than 0.005 vs. baseline, p less than 0.02 vs. 1 hr value) at 24 hr, and pulmonary capillary wedge pressure fell from 13.1 +/- 0.9 to 11.1 +/- 1.3 mm Hg 1 hr after large-volume paracentesis and to 9.89 +/- 1.2 (p less than 0.01 vs. baseline, p less than 0.03 vs. 1 hr after large-volume paracentesis) at 24 hr. Heart rate fell from 90 +/- 3.0 to 85 +/- 2.9 beats per min (p less than 0.01) 1 hr after large-volume paracentesis completion, but increased to 89 +/- 2.5 beats per min (p less than 0.02 vs. 1 hr after large-volume paracentesis) at 24 hr.(ABSTRACT TRUNCATED AT 250 WORDS)
