Effect of a silane coupling agent on the properties of white rice husk ash–polypropylene/natural rubber composites (2001)

Abstract White rice husk ash (WRHA)–polypropylene (PP)/natural rubber (NR) composites were prepared using a Brabender Plasticorder at 180 °C and a rotor speed of 50 rev min −1 . The mechanical and water‐absorption properties were studied. The incorporation of WRHA into the PP/NR matrix has resulted in the improvement of the tensile modulus; however, the tensile strength, elongation at break and stress at yield decreased with increasing WRHA loading. Poor filler matrix interactions are believed to be responsible for the decrease in the properties. Incorporation of a silane coupling agent, 3‐aminopropyl triethoxysilane (3‐APE), improved tensile modulus, tensile strength and stress at yield of the composites. Water‐absorption studies indicate that the use of the coupling agent reduced the amount of water absorbed by the composites. © 2001 Society of Chemical Industry

Physics of optical switching (1982)

Relatively fundamental problems in physics hinder realization of large information-handling capability offered by optical switching. This paper examines the physics of optical switching in a way which exhibits those problems and which suggests strategies for their solution. The primary limits on optical switches arise from heat generated during the switching process. The principal barriers to easing those limits are the small value of interaction cross sections for atoms in solid-state materials and the lack of high-finesse microresonators for the optical field. The research most relevant to the solution of these problems appears to be that dealing with enhanced atom---optical-field interactions in solid-state microstructures. Short-optical-pulse generation and the short-time dynamics of solid-state microstructures are also highly relevant.
5-METHYL-1,2,3-CYCLOHEXANETRIONETRIOXIME: A COMPARATIVE STUDY WITH SOME <i>vic</i>-DIOXIMES (1962)

A comparative study has been made of 5-methyl-1,2,3-cyclohexanetrionetrioxime with nioxime and dimethylglyoxime; complexes with nickel, copper, and cobalt have been investigated. Dissociation constants of the three reagents, in aqueous solution, have been determined and formation constants of their copper complexes evaluated. Spectrophotometric and potentiometric studies were used to obtain the results.
E-business Websites Evaluation Based on Opinion Mining (2009)

With the popularization and development of Internet, as a new business methodology, e-business Web sites are attracting the attention of public and springing with fierce competition. How to make the Web sites invincible and how to help the potential customers make decisions? The only way is to make a comprehensive and accurate evaluation of the sites. Many traditional approaches have done this job, which are mostly qualitative and subjective. In this paper, we propose a new approach based on opinion mining. Through the reviews customers have posted we can mining the evaluation of various Web site indexes quantitatively. To improve the accuracy of the mining results we use a approach called MRA (mutual reinforcement approach). Different from the vast majority of opinion mining methods centering on mining explicit factor-opinion pairs, the MRA can mining implicit pairs effectively based on a pre-constructed association set. The biggest flash point of our evaluation approach is that it is customer-oriented and therefore more credible and trustworthy than traditional approach. The experimental study and evaluation show that the results by the proposed approach are consistent with the traditional approach but more reliable.
Microbial role in periodontitis: Have we reached the top? Some unsung bacteria other than red complex (2014)

The microbial etiology of periodontal disease has been the focus of researchers for a long time. The search for the pathogens of periodontal diseases has been underway for more than 100 years, and continues up today. Despite the increasing knowledge about oral microbiota, we are not able to implicate any one particular organism that can be considered as a candidate pathogen. In fact the term "candidate pathogen" has lost its steam with a myriad of microorganisms being incriminated from time to time. Most studies of the bacterial etiology of periodontitis have used either culture-based or targeted deoxyribonucleic acid approaches and so it is likely that pathogens remain undiscovered. The advent of 16S cloning and sequencing has facilitated identification of several uncultivable bacteria in the oral cavity. The concept that not one single organism, but several organisms contained in the biofilm orchestrating in a medley of the show appears to be more plausible. The present review highlights some lesser known bacteria associated with periodontal destruction.
Cytokine profile (<scp>IL</scp>‐2, <scp>IL</scp>‐6, <scp>IL</scp>‐17, <scp>IL</scp>‐22, and <scp>TNF</scp>‐α) in vitiligo—New insight into pathogenesis of disease (2018)

Our study shows that cytokines secreted by Th17 cells play an important role in maintenance and spread of vitiligo as they increase in line with extent of disease. Also TNF-α increases in proportion with activity of disease, hence may act as biomarker for identifying patient with aggressive disease.
<i>Helicobacter pylori:</i>isolation from gastric biopsy specimens (1993)

Forty-two gastric biopsies, in two transport media, were homogenized and cultured on three media under micro-aerophilic conditions. Brain-heart infusion agar with a commercial antibiotic supplement (giving 10 mg vancomycin, 5 mg trimethoprim and 2500 i.u. polymixin per litre) yielded the best results. Ordinary chocolate (heated) human blood agar could be used in laboratories with limited resources. Growth was obtained in 4-6 days at 37 degrees C. All isolates were sensitive to metronidazole. The resistance to nalidixic acid and rapid urease production of Helicobacter pylori could be used to differentiate this species from Campylobacter spp. Indicator medium (brain-heart infusion broth with 7% human blood and 40 mg 2,3,5-triphenyletetrazolium chloride agar/litre) also proved useful in identification.
The Est1 Subunit of <i>Saccharomyces cerevisiae</i> Telomerase Makes Multiple Contributions to Telomere Length Maintenance (2002)

The telomerase-associated Est1 protein of Saccharomyces cerevisiae mediates enzyme access by bridging the interaction between the catalytic core of telomerase and the telomere-binding protein Cdc13. In addition to recruiting telomerase, Est1 may act as a positive regulator of telomerase once the enzyme has been brought to the telomere, as previously suggested by the inability of a Cdc13-Est2 fusion protein to promote extensive telomere elongation in an est1-Delta strain. We report here three classes of mutant Est1 proteins that retain association with the telomerase enzyme but confer different in vivo consequences. Class 1 mutants display a telomere replication defect but are capable of promoting extensive telomere elongation in the presence of a Cdc13-Est2 fusion protein, consistent with a defect in telomerase recruitment. Class 2 mutants fail to elongate telomeres even in the presence of the Cdc13-Est2 fusion, which is the phenotype predicted for a defect in the proposed second regulatory function of EST1. A third class of mutants impairs an activity of Est1 that is potentially required for the Ku-mediated pathway of telomere length maintenance. The isolation of mutations that perturb separate functions of Est1 demonstrates that a telomerase holoenzyme subunit can contribute multiple regulatory roles to telomere length maintenance.
Magnetic resonance imaging in ischaemic heart disease. (2003)

Magnetic resonance imaging has an increasing role in the assessment of ischaemic heart disease. Its superb spatial and temporal resolution currently allows accurate assessment of cardiac function, regional wall motion, and the extent of myocardial infarction. Regional myocardial perfusion can also be assessed, most commonly by a first-pass technique. Non-invasive imaging of the coronary arteries by various magnetic resonance imaging techniques represents a major advance in recent years. In the foreseeable future, magnetic resonance imaging may become a single, comprehensive examination for the assessment of ischaemic heart disease.
Hybrid simulation of foreshock waves and ion spectra and their linkage to cusp energetic ions (2009)

A three‐dimensional global hybrid simulation is carried out to investigate energetic ions and electromagnetic waves in the quasi‐parallel (Q‐∥) bow shock and cusp for a typical interplanetary magnetic field configuration during the cusp energetic particle events. The bow shock, magnetosheath, and dayside magnetosphere form by interaction between the solar wind and geomagnetic dipole field. Ions of solar wind characteristics injected into the system evolve along with electromagnetic waves in a self‐consistent manner. Several important features are yielded from the simulation. Solar wind ions are accelerated by the waves and turbulence at the bow shock and foreshock as indicated by the ion distribution. The shock‐accelerated ions possess an exponential energy spectrum with their differential flux scaled by the field‐aligned distance to the bow shock, consistent with satellite observations. Second, the compressive and transversal waves in the foreshock are strongly correlated with the diffuse ion dynamics. Third, energetic ions in the magnetosheath and cusp downstream from the Q‐∥ shock also exhibit a spectrum similar to those at the shock. By tracing trajectories of cusp energetic ions in the simulation, the origin of these ions is revealed. Their source is predominantly associated with the Fermi acceleration at the Q‐∥ shock and foreshock. Waves in the magnetosheath and cusp, as well as magnetic reconnection at the high‐latitude magnetopause, are relatively insignificant in accelerating cusp energetic particles.
Can quantum probability provide a new direction for cognitive modeling? (2013)

Classical (Bayesian) probability (CP) theory has led to an influential research tradition for modeling cognitive processes. Cognitive scientists have been trained to work with CP principles for so long that it is hard even to imagine alternative ways to formalize probabilities. However, in physics, quantum probability (QP) theory has been the dominant probabilistic approach for nearly 100 years. Could QP theory provide us with any advantages in cognitive modeling as well? Note first that both CP and QP theory share the fundamental assumption that it is possible to model cognition on the basis of formal, probabilistic principles. But why consider a QP approach? The answers are that (1) there are many well-established empirical findings (e.g., from the influential Tversky, Kahneman research tradition) that are hard to reconcile with CP principles; and (2) these same findings have natural and straightforward explanations with quantum principles. In QP theory, probabilistic assessment is often strongly context- and order-dependent, individual states can be superposition states (that are impossible to associate with specific values), and composite systems can be entangled (they cannot be decomposed into their subsystems). All these characteristics appear perplexing from a classical perspective. However, our thesis is that they provide a more accurate and powerful account of certain cognitive processes. We first introduce QP theory and illustrate its application with psychological examples. We then review empirical findings that motivate the use of quantum theory in cognitive theory, but also discuss ways in which QP and CP theories converge. Finally, we consider the implications of a QP theory approach to cognition for human rationality.
Anchorage-independent growth conditions reveal a differential SOS2 dependence for transformation and survival in <i>RAS</i>-mutant cancer cells (2019)

The RAS family of genes (<i>HRAS, NRAS</i>, and <i>KRAS</i>) is mutated in around 30% of human tumours. Wild-type RAS isoforms play an important role in mutant RAS-driven oncogenesis, indicating that RasGEFs may play a significant role in mutant RAS-driven transformation. We recently reported a hierarchical requirement for SOS2 in mutant RAS-driven transformation in mouse embryonic fibroblasts, with KRAS>NRAS>HRAS (Sheffels et al., 2018). However, whether <i>SOS2</i> deletion differentially affects mutant RAS isoform-dependent transformation in human tumour cell lines has not been tested. After validating sgRNAs that efficiently deleted <i>HRAS</i> and <i>NRAS</i>, we showed that the differential requirement for SOS2 to support anchorage-independent (3D) growth, which we previously demonstrated in MEFs, held true in cancer cells. <i>KRAS</i>-mutant cells showed a high dependence on SOS2 for 3D growth, as previously shown, whereas <i>HRAS</i>-mutant cells did not require SOS2 for 3D growth. This differential requirement was not due to differences in RTK-stimulated WT RAS activation, as SOS2 deletion reduced RTK-stimulated WT RAS/PI3K/AKT signalling in both <i>HRAS</i> and <i>KRAS</i> mutated cell lines. Instead, this differential requirement of SOS2 to promote transformation was due to the differential sensitivity of RAS-mutated cancer cells to reductions in WT RAS/PI3K/AKT signalling. <i>KRAS</i> mutated cancer cells required SOS2/PI3K signaling to protect them from anoikis, whereas survival of both <i>HRAS</i> and <i>NRAS</i> mutated cancer cells was not altered by SOS2 deletion. Finally, we present an integrated working model of SOS signaling in the context of mutant KRAS based on our findings and those of others.

A REVIEW ON FRACTAL ANTENNAS FOR WIRELESS COMMUNICATION (2015)

The demand of compact size antennas is increasing day by say because of the rapid growth of portable devices and wireless communication technology. In this paper, we provide overview of recent developments in the rapidly growing fields of fractal antenna engineering. Here Sierpinski fractal antenna has been proposed and presented. Traditionally each antenna operates at a single or dual frequency bands where different antenna is needed for different applications. Low cost of fabrication and low profile features of microstrip antenna attract many researchers to investigate the performance of this antenna in various ways. Effect of antenna iterations stresses upon reducing metal usage thereby saving cost and also achieved good reflection coefficient. Recent studies on fractal antennas show that these structures have their own specific characteristic that improve certain properties when talking about low profile antennas.
Centrifugal Extrusion Encapsulation (1995)

Centrifugal extrusion encapsulation is suitable for specialty applications requiring protection of food ingredients. This technique offers a process for formulating with a variety of shell materials including gelatin, alginates, carrageenan, starches, fats, and waxes. Shell systems may be a blend of two or more polymers to obtain the desired characteristics. Capsule size capability of the process is in the range of 150-2000 μm, with the "comfort range" being in the 500-1000 μm range. Loadings of 20-80% can be obtained.
Naked DNA injection for liver metastases treatment in rats (2002)

The cytosine deaminase (CD) gene converts the nontoxic prodrug, 5-fluorocytosine (5-FC), into 5-fluorouracil (5-FU). We previously showed that injection of CD-bearing cancer cells followed by 5-FC treatment can act as an autologous tumor vaccine in a syngenic liver metastasis model in rats. In the present work, we analyzed the antitumor efficiency of a direct intratumoral injection of a CD-expressing plasmid. In rats bearing microscopic or macroscopic metastases in right and left liver lobes, an injection of a CD-expressing plasmid was performed in the left lobe tumor, followed by 5-FC treatment of the animals. A significant regression of the DNA-injected tumor was observed in 5-FC-treated rats, both in microscopic (P =.007) or advanced (P <.0001) tumor models. Moreover, this treatment also induced a potent distant bystander effect on untreated controlateral liver tumors and extrahepatic metastases, resulting in an increased survival compared with control animals in both tumor models (P <.05). In conclusion, these data suggest that direct intratumoral injection of a CD-expressing plasmid, associated to 5-FC administration, can constitute a powerful and innocuous alternative treatment for unresectable liver metastases from colon carcinoma.

The artificial kidney in North America: George Murray and the Canadian connection. (1989)

Approximately 50 years after the Scottish chemist Thomas Graham described the process of selective diffusion in solutions (dialysis) in 1861, a Johns Hopkins University team led by John J. Abel purified animal blood using celloidin membranes. Termed "vividiffusion" by Abel, these limited but successful experiments were abandoned in 1914. The most successful artificial kidney machine was later devised by Willem J. Kolff in Holland during the early 1940s; this basic design later developed into a commercially successful venture in America. Other mechanical hemodialysis equipment was also invented, such as that of Canadian surgeon George Murray (1894-1976), who devised the first artificial kidney machine in North America in 1946. Blood to be filtered was gently pumped through a vertical helical coil of cellulose acetate tubing (the dialyzing membrane) placed in a salt-buffered tapwater solution. Four patients were treated in this manner, all of whose blood was purified; however, two of this group later died due to chronic kidney problems. Murray's artificial kidney was never developed commercially owing to Kolff's more efficacious design and, it is contended here, due to the failure of Canadians to capitalize on domestic technological innovations. It is also suggested that as it is an example of simultaneous invention, a further exploration of the artificial kidney might reveal insights into the historical development of modern medical technology.

Tyrosinase‐mediated <i>in situ</i> forming hydrogels from biodegradable chondroitin sulfate–tyramine conjugates (2012)

Abstract Tyrosinase‐mediated crosslinking of chondroitin sulfate–tyramine (CS‐TA) conjugates was successfully applied in the preparation of biodegradable in situ forming hydrogels under physiological conditions. Depending on the polymer concentration, the degree of substitution of TA residue and the tyrosinase concentration, the gelation times ranged from 2.3 to 129 min. Studies on the gel contents of CS‐TA hydrogels showed that their degrees of crosslinking could be controlled by varying the tyrosinase concentrations. CS‐TA hydrogels could be completely degraded by the chondroitinase ABC within a time range from 6 days to 11 weeks. CS‐TA hydrogels possessed highly elastic properties and their storage moduli varied from 120 to 1300 Pa, as determined by rheological analysis. Scanning electron microscopy observation confirmed that CS‐TA hydrogels contained a well‐interconnected pore structure. A live–dead assay demonstrated that NIH 3T3 fibroblasts incorporated in CS‐TA hydrogels retained their viability. In addition, in vitro release of methylene blue (a photodynamic therapy drug) from CS‐TA hydrogels could be effectively sustained by the drug encapsulation in the hydrogels. This study indicates that tyrosinase‐mediated in situ forming CS‐TA hydrogels are promising for biomedical applications including drug release and tissue engineering. © 2012 Society of Chemical Industry
Cross-eye jamming of monopulse radar (2007)

Radar seeking missiles present a serious threat towards ships and aircraft. In cross-eye jamming a missile seeker is deflected by signals from two onboard antennas transmitting out of phase with signals of nearly equal strength. The limits on cross-eye performance imposed by scattering have been studied when scattering takes place far from the propagation path. It will be shown that a digital cross-eye system with several antenna units can be seriously affected by scattering from sea waves and terrain.
