Comparative assessment of Cranberry and Chlorhexidine mouthwash on streptococcal colonization among dental students: A randomized parallel clinical trial

Background: Chlorhexidine gluconate mouthwash has earned an eponym of the gold standard against oral infections, but with certain limitations. There is no effective alternative to Chlorhexidine. Cranberry is known to inhibit bacterial adhesion in various systemic infections and acts as a strong antioxidant. However, it is less explored for its dental use. Hence, there is a need to evaluate its effect against oral infections. Aim: The aim was to compare the efficacy of 0.2% Chlorhexidine mouthwash with 0.6% Cranberry mouthwash on Streptococcus mutans. Materials and Methods: This was a double-blind, randomized parallel group clinical trial. Total sample of 50 subjects, aged 18-20 years, were randomly divided into two groups, Group A (25) and Group B (25) were given 10 mL of Chlorhexidine mouthwash and Cranberry mouthwash twice daily, respectively, for 14 days each. The plaque samples, which were taken from the subjects on 1 st day and 14 th day, were inoculated on blood agar plates and incubated at 37΀C for 24-48 h. Number of streptococcal colony forming units were calculated using digital colony counter. The data were subjected to paired t-test and unpaired t-test at a 5% significance level. Results: (1) Chlorhexidine mouthwash showed 69% reduction whereas Cranberry mouthwash showed 68% reduction in S. mutans count. (2) No significant difference was seen between Chlorhexidine and Cranberry mouthwash on streptococci. Conclusion: Cranberry mouthwash is equally effective as Chlorhexidine mouthwash with beneficial local and systemic effect. Hence, it can be used effectively as an alternative to Chlorhexidine mouthwash.
Contribution à l'intégration des systèmes de commande des machines électriques à courant alternatif

L’integration des systemes de commande electriques n'a ete l'objet que de travaux marginaux dont aucun n'a envisage jusqu'a present une approche systematique du probleme. Actuellement, l'integration de la commande fait appel la plupart du temps a un processeur specialise type micro conducteur ou DSP couple parfois a un ASlC, dedie a la generation des impulsions MLI de commande de l'onduleur. Cette approche de conception est peu reactive face aux changements de specification et ne permet pas de traiter certains problemes que nous identifions dans cette these (verification des modeles, exploration de l'espace des solutions, etc. . . ). Pour resoudre ces problemes, nous proposons d’utiliser une methodologie de conception mixte materiel/logiciel qui consiste a developper ensemble le la partie materiel (ASIC) et la partie logiciel (processeur) du systeme integre a partir d'un modele de specification commun. Comme notre approche se limite aux systemes de commande, nous avons adapte certaines tâches de. Conception pour traiter des problemes specifiques tell que la preuve formelle des proprietes mathematiques du systeme. A partir de cette methode, nous pouvons alors flot de conception utilisant differents langages (VHDL, Grafcet, Script MA TLAB) et outils correspondants. Dans le cas du Grafcet, nous montrons qu'en modifiant ses regles de fonctionnement en se basant sur l'hypothese de syncl1ronisme fort. Il devient possible de modeliser les fonctionnel. En se basant sur un ensemble de regles et de techniques que nous definissons, on peut alors analyser les modeles Grafcet en vue de l'integration. Pour montrer la validite de la demarche adoptee. Nous avons integre, sous forme d'ASIC, un algorithme de controle vectoriel de moteur asynchrone. Au niveau de chaque etape de conception, les solutions aux differents problemes sont exposees En particulier, nous proposons d’utiliser l’algorithme CORDIC pour calculer le plupart des fonctions mathematiques (p. E. Les rotations). Finalement. I'ASIC a ete prototype avec un FPGA et connecte au banc d’essai (onduleur, moteur et charge). Grace aux mesures de courant, de tension et de couple, le systeme integre a pu etre valide.

L Fibroblast Phospholipid Acyl Group Composition and Triacylglycerol Levels: Response to Continuous Fatty Acid Infusion

Abstract Two methods of administering fatty acids to cells in culture were compared for their effects on growth, phospholipid acyl group composition, and triacylglycerol formation. Solutions of fatty acid salts were delivered to suspension cultures of L fibroblasts either by infusion at a constant rate over 48 hr, or an amount of fatty acid equal to that infused was added as a single dose complexed to albumin at the start of the 48-hr incubation period. With an initial cell density of 2.5 × 105/ml, 5-18 μmole of Na oleate could be delivered by either method with no adverse effects on the cells. Linoleate (18:2) at the high end of this range, however, decreased culture growth by as much as 50% when the infusion method was employed and 15% when the fatty acid was added as a single dose. At low doses, 5 μmole, 18:2 had little effect on the growth rate. Over a 48-hr period infusion of 5 μmole of 18:2 caused the dienoic acyl group content of phospholipid to increase 22-fold, while the single-dose method increased it by a factor of 18. Time-course studies showed that the triacylglycerol content in the latter case increased to max levels from the 6th to the 24th hr at least 60 times greater than that of control cells not supplemented with fatty acid. The max increase in triacylglycerol above control levels during infusion of 18:2 was only 8-fold and occurred at 24 hr. The infusion method at low levels of 18:2 is at least as effective as the single-dose method in modifying phospholipid acyl group composition, but had the advantage of maintaining lower levels of triacylglycerol.
Time constraints for sellers in electronic markets

Electronic markets provide virtual places for negotiation over the exchange of products. In such places entities representing buyers and sellers can interact and agree upon a product price. Both parties try to maximize their profit. The authors model such an interaction as a finite horizon bargaining game and try to quantify the maximum time of seller participation in the game. The estimated deadline indicates until when the interaction is profitable for the seller. The authors’ model defines the appropriate value for a patience factor which finally results in the seller deadline fully adapted in each product characteristics.
Effect of CPAP therapy on daytime function in patients with mild sleep apnoea/hypopnoea syndrome.

BACKGROUND: Continuous positive airway pressure (CPAP) is an effective treatment in patients with moderate and severe sleep apnoea/hypopnoea syndrome (SAHS), but the minimum illness severity at which patients obtain benefit from CPAP is unclear. A study was therefore undertaken to investigate whether CPAP improves symptoms and daytime function in patients with mild SAHS. METHODS: Sixteen consecutively recruited patients with mild SAHS (5.0-14.9 apnoeas + hypopnoeas per hour slept and two or more symptoms of SAHS) participated in a prospective placebo controlled randomised crossover trial to assess the effects of CPAP on symptoms and daytime function. Patients spent four weeks on placebo and four weeks on CPAP, undergoing assessments of sleepiness, symptoms, cognitive performance, and well being on the last day of each treatment. Data from the placebo and CPAP assessments were compared. RESULTS: The mean (SE) objective effective use of CPAP was 2.8 (0.7) hours per night. Significant improvements in symptom score (-1.7 (0.5), p < 0.01), mental flexibility (-14 (5) seconds, p = 0.02), and depression rating (-1.6 (0.8), p = 0.03) on CPAP were observed. However, no significant differences in subjective or objective sleepiness were found. Ten of the 16 patients preferred CPAP and opted to continue with this treatment, although this proportion was non-significant (p > 0.4). The eight patients with best CPAP use showed an additional CPAP related improvement in quality of life (-4.4 (1.8), p = 0.03). Those who complied better with CPAP therapy also had a higher average microarousal frequency (p < 0.01) and apnoea+hypopnoea index (p = 0.02) than the poorer compliers. CONCLUSIONS: The results of this study provide evidence for improvements in symptoms and daytime function for patients with mild SAHS treated with CPAP.
Analyses structurales et fonctionnelles des interactions entre elF4E et ses partenaires

Le controle traductionnel est une etape critique de la regulation de l'expression des genes impliques dans le developpement embryonnaire et de nombreux processus cellulaires. Au cours de l'initiation de la traduction chez les eucaryotes, le facteur eIF4E (eukaryotic Initiation Factor 4E) fixe la coiffe des ARNm et recrute la proteine eIF4G pour former le complexe d'initiation. L' interaction eIF4E/eIF4G est une etape cle de la regulation traductionnelle, faisant du site de liaison a eIF4E un lieu de competition entre eIF4G, le represseur general de la traduction 4E-BP et d'autres regulateurs appeles 4E-IPs (4E-interacting partners), qui partagent avec eIF4G un motif consensus de liaison a eIF4E. Longtemps consideree comme une proteine desordonnee, nous avons montre au cours de cette these que 4E-BP adopte en realite une conformation repliee lorsqu'il se lie a eIF4E, impliquant une surface d'interaction plus importante. Ces resultats ont apporte un nouveau regard sur les interactions qui s'etablissent entre eIF4E et ses partenaires, et ont fourni des informations cruciales pour l'etablissement de nouvelles therapies, notamment celles developpees dans le cadre des cancers. Mon travail de these a egalement permis l'etablissement d'un criblage de nouvelles 4E-IPs, base sur une approche alliant analyses structurales, bioinformatiques et biochimiques. Parmi les 4E-IPs detectees, nous avons caracterise la proteine Angel1, membre d'une famille de deadenylases. Ces resultats ont ouvert de nombreuses perspectives pour la comprehension du metabolisme des ARNm mais aussi celle des regulations traductionnelles specifiques prenant pour cible moleculaire eIF4E
An evaluation of the effectiveness of the co-management approach in selected protected areas of Bangladesh

This study undertook a qualitative approach to evaluate the perceptions and attitudes of stakeholders towards the effectiveness of planning and management, in three protected areas in Bangladesh. A complex socio-economic context was revealed, within which there were diverse views leading, in some cases, to ongoing conflict and difficulty in law enforcement. While the co-management approach in theory takes the interests of local people into account and so has a better prospect for long term, sustainability, and forest protection, this research revealed that community participation is not currently effective. Recommendations are made to remedy to increase the potential towards achieving the management objectives for these protected areas. Key words: Co-management, protected areas, Bangladesh.
On the Number of Intensity Levels Discriminated in Textures

The number of intensity levels detected in briefly displayed textures was studied as a function of two related spatial parameters: granularity and spatial frequency. A texture-discrimination paradigm was used to determine the discriminability of an original texture and of a version of it reduced (further ‘quantized’) in intensity levels over a range of texture granularities and frequency bandwidths. Results show specific sensitivities to intensity level reductions as a function of the spatial-frequency composition of the textures, with particular loss of sensitivity in the higher spatial-frequency regions.
A Review on Intrusion Detection System Using Data Mining Technique : Support Vector Machine Ms

Intrusion Detection is the problem of identifying unauthorized use, misuse and abuse of computer systems. Outside attacks are not the only problem, the threat of authorized users misusing and abusing their privileges is an equally pressing concern. The proliferation of heterogeneous computer networks has additional implications for the intrusion detection problem. Namely, the increased connectivity of computer systems gives greater access to outsiders and makes it easier for intruders to cover their tracks. Therefore, the goals of an Intrusion Detection System (IDS) are to use all available information in order to detect both attacks by external hackers and misuse by insiders. IDS are based on the belief that an attacker's behaviour will be noticeable different from that of a legitimate user.Here, the focus is on Intrusion Detection System using data mining technique: SVM (Support Vector Machine). Classification is done by using SVM and comparative analysis of the system is done with neural network. Verification regarding the effectiveness of the system is done by conducting different experiments on different datasets such as, NSL-KDD Cup’99 and DARPA. Keywords-: Classification, Intrusion Detection System (IDS), NSLKDD, Support Vector Machine (SVM), Neural Network (NN).
The morphology-semantics interface in word formation

espanolEl proposito principal de este articulo es extender la propuesta acerca de la descomposicion lexica, presentada por Mairal and Ruiz de Mendoza (en este volumen), al estudio de los procesos de formacion de palabras. Para ello, se estudian en detalle las condiciones que Lieber establece con respecto a la configuracion de una teoria de representacion lexica semantica y se evalua su papel en el diseno de un marco adecuado para el tratamiento de la composicion semantica en la formacion de palabras. En consonancia con el Modelo Lexico Construccional, el argumento central de este articulo es que tanto los morfemas libres como los morfemas trabados constituyen predicados y, por tanto, ambos deben definirse segun un mismo tipo de representacion semantica. Asi, al igual que las plantillas lexicas de palabras, las plantillas lexicas afijales incorporan aspectos centrales de la Teoria de Qualia de Pustejovsky EnglishThe main purpose of this paper is to expand the proposal for lexical decomposition presented in Mairal and Ruiz de Mendoza (this volume) as to cover word-formation processes. In doing so, Lieber’s conditions for a theory of lexical semantic representations is considered in detail as well as their role in the design of an adequate framework for a proper treatment of the processes that motivate semantic composition in word formation. In line with the Lexical Constructional Model, the central claim of this paper is that both free and bound morphemes are lexical predicates and, therefore, both are to be defined in terms of the same kind of semantic representation. Much like word lexical templates, affixal lexical templates are thus enriched by incorporating central aspects of Pustejovsky’s Qualia Theory
Changes in Wind Pattern Alter Albatross Distribution and Life-History Traits

Riding the Wind Pelagic seabirds rely on wind to move between breeding and foraging areas, and albatrosses—which travel thousands of kilometers over sea—are well-known wind riders. Weimerskirch et al. (p. 211; see the cover) monitored foraging and reproduction in wandering albatrosses over 40 years and found that a change in wind patterns, probably induced by climate change, had a notable impact on important life history traits. Greater wind strength increased the rate of travel for the birds and shortened their foraging trips. These shorter trips improved breeding success and resulted in an increase in adult mass. Thus, over the past half-century, environmental changes have improved conditions for the albatross. Changing wind patterns in the Southern Ocean have improved foraging conditions for wandering albatrosses. Westerly winds in the Southern Ocean have increased in intensity and moved poleward. Using long-term demographic and foraging records, we show that foraging range in wandering albatrosses has shifted poleward in conjunction with these changes in wind pattern, while their rates of travel and flight speeds have increased. Consequently, the duration of foraging trips has decreased, breeding success has improved, and birds have increased in mass by more than 1 kilogram. These positive consequences of climate change may be temporary if patterns of wind in the southern westerlies follow predicted climate change scenarios. This study stresses the importance of foraging performance as the key link between environmental changes and population processes.

Drug prices and emergency department mentions for cocaine and heroin.

OBJECTIVES In this report, the author illustrates the historic relation between retail drug prices and emergency department mentions for cocaine and heroin. METHODS Price series based on the Drug Enforcement Administration's System to Retrieve Information From Drug Evidence database were correlated with data on emergency department mentions from the DrugAbuse Warning Network for cocaine (1978-1996) and heroin (1981-1996). RESULTS A simple model in which emergency department mentions are driven by only prices explains more than 95% of the variation in emergency department mentions. CONCLUSIONS Fluctuations in prices are an important determinant of adverse health outcomes associated with drugs.
ENGAGEMENT WITH SOCIAL MEDIA CONTENT: A QUALITATIVE EXPLORATION

A lack of a consensus regarding what constitutes engagement in the context of social media has made it difficult for scholars to generate theory in this area and has created challenges for managers attempting to demonstrate positive outcomes stemming from social media marketing. To address this issue, qualitative studies are undertaken with marketing practitioners and consumers to provide clarification and to formulate a formal definition of engagement in this context. The studies reveal it to be a psychological state of mind operating independently from interactive behaviors such as “liking” and sharing content. The findings offer new insight into consumer consumption of social media content and sow the seeds for future exploration.
Optimization of linear permanent magnet synchronous motors for needle-free jet injection

We present a scaling model for linear permanent magnet synchronous motors applied to needle-free jet injection, a drug delivery technique that requires the generation of high fluid pressures. This model shows that either the motor stroke or the motor constant can be increased to reduce the electrical power required to perform an injection. We then present computationally efficient semi-analytical field solutions for a tubular linear synchronous motor, and use them to develop optimized motor designs for minimal jet injection power. A finite-permeability solution is developed and compared to both finite element results and a simplified infinite-permeability solution to validate the model and to establish criteria for choosing the back-iron thickness. We find that optimal jet injector motor configurations favor long stroke lengths, even at the expense of motor constant. However, designs constrained to physically reasonable motor lengths still offer an order of magnitude reduction in input power as compared to existing voice-coil-driven injection systems.
Investigation of the Tilera processor for real time hazard detection and avoidance on the Altair Lunar Lander

The High Performance Processor (HPP) Task of the Advanced Avionics and Processor Systems (AAPS) Project, part of the Exploration Technology Development Program (ETDP), was to evaluate several high performance multicore processor architectures with respect to their ability to provide real time hazard detection and avoidance for the Constellation Program's Altair Lunar Lander. 12In this paper we review the Tilera Tile64 processor, the hazard detection and avoidance algorithm, strategies for parallelizing these algorithms, and preliminary performance study results. We were presented with the requirements of 30 Hz LIDAR frame processing rate and 10 second processing time for ALHAT HDA processing and were able to meet that requirement with the Tile64. We then project the performance of these algorithms on the OPERA MAESTRO Processor, a radiation tolerant version of the Tile 64 being developed by the Boeing Company.
Feasibility Study on Stability of Gait Patterns with Changeable Body Stiffness Using Pneumatic Actuators in a Quadruped Robot

An oscillator-type gait controller for a quadruped robot with antagonistic pairs of pneumatic actuators is proposed. By using the controller, a feasibility study on the stability of gait patterns with changeable body stiffness is reported. The periodic motions of the legs are generated and controlled by an oscillator network with state resetting. This type of controller has robustness in its gaits against variation in walking conditions or changes of environment. However, it sometimes loses robustness under conditions of actuation delay, decrease of actuator accuracy, etc. We investigated whether an oscillator-type controller with phase resetting is also effective under such conditions. The stability of locomotion also strongly depends on the mechanical properties of the body mechanism, especially the joint stiffness. In this report, the muscle tone of the robot on the pitching motion at the trunk is changeable by using the changeable elasticity of the pneumatic actuators. The stability of quadruped locomotion in walk and trot patterns with changeable body stiffness was evaluated with numerical simulations and hardware experiments.
