Eficacia del pyriproxyfeno en cepas de referencia de Aedes aegypti susceptible y resistente a temefos

Introduction: intensive use of chemical larvicide temephos (abate) in Cuba has resulted in the development of resistance mechanisms in Aedes (Stegomyia) aegypti (Linnaeus, 1762). Therefore, there is an urgent need to consider other control alternatives, such as pyriproxyfen, a growth inhibitor. Objectives: determine the efficacy of pyriproxyfen as larvicide, pupicide and adulticide in reference strains of Aedes aegypti and establish its effect on reproduction. Methods: the study was based on a strain of reference Aedes aegypti susceptible to temephos (Rockefeller) and a strain resistant to temephos (SANtemF13). Pyriproxyfen was evaluated with bioassays recommended by the World Health Organization. Determination was made of the effect of pyriproxyfen on reproduction by measuring fecundity and egg viability (fertility) in larvae of the Rockefeller strain surviving sublethal doses of pyriproxyfen. Results: in the Rockefeller strain, pyriproxyfen was larvicidal in 32 %, pupicidal in 21 % and adulticidal in a mere 1 %. In the SANtem F13 strain, it was larvicidal in 31 %, pupicidal in 12 % and adulticidal in 1 %. Analysis of variance between ranges of lethal doses for larvae, pupas and adults of the reference strains Rockefeller and SANtem F13 did not show any significant differences (p= 0.000001). Pyriproxyfen was found to be an excellent inhibitor of adult emergence in the strains of Aedes aegypti studied when used at low concentrations, below those recommended by the World Health Organization for mosquitoes of the genus Aedes. It also showed a strong sublethal effect and affected the fertility of adults in laboratory conditions. Conclusion: growth inhibitor pyriproxyfen is a good alternative to be included among integrated control strategies against Aedes aegypti in Cuba without affecting its efficacy, due to the resistance that this species has developed to larvicide temephos.
The Image Retrieval and Relevance Feedback Methods Based on Region

Traditional image retrieval method based on global features can only extract low-level features, which are far from the semantics that human expects. So there is a huge gap between low-level features and high-level semantics. In order to overcome this gap, two approaches have been widely used: high-level semantic image representation and relevance feedback. The paper is based on region representation that comes closely to the semantics. Region-based image retrieval (RBIR) can effectively exclude the affection of backgrounds. The main work in the paper is summarized as follows: Firstly in order to solve the problems of image segment and similarity measure, an algorithm about detecting visual attended region with respect to image segment is proposed in the paper. This algorithm combined human visual attention model can effective detect the meaningful regions. And the paper proposes a similarity measure algorithm named Modified Integrated Region Matching (MIRM), which is more robust for over segmented images. Secondly this paper focuses on the applications of relevance feedback in RBIR. By studying three cases that may occur in relevance feedback respectively, this paper introduces some relevance feedback algorithms. Those are image coding and cluster based relevance feedback algorithm, Mapping Convergence (MC) based relevance feedback algorithm, Adaptive Boosting (AdaBoost) Support Vector Machines (SVM) based relevance feedback algorithm, Asymmetric Bagging SVM based relevance feedback algorithm and region representation based SVM relevance feedback algorithm. A large number of experimental results demonstrate that all the algorithms, both region based image representation and relevance feedback, proposed in this paper can improve the performance and efficiency of image retrieval.

Counseling Intervention Programme to Improve Knowledge and Attitude towards Smoking among Adolescents in Two Districts in Selangor, Malaysia

The objective of this study is to identify the profile of adolescent smokers and to measure the level of knowledge and attitude among smoking adolescents before and after the implementation of an intervention programme. 24 schools in two districts in the state of Selangor, Malaysia were selected by a simple random sampling. 346 students who have the intention to stop smoking were enrolled in the study. Students who agreed to participate in a group counseling were enrolled into the intervention programme (n = 158) while the remaining (n=188) were followed up in the nonintervention group. Group counseling was implemented by trained counselors using a smoking cessation package developed by the research group for a period of four months. The students were followed up for duration of one year. The level of knowledge and attitude were measured before the intervention, immediately after the intervention and during the follow up at fourth and eighth month after the intervention. The mean scores of knowledge and attitude at baseline for intervention and nonintervention groups are comparable. At second, third and fourth visit, mean scores of knowledge increased among students in the intervention group, while for the non-intervention group, the mean score knowledge raised at second visit but reduced at third and fourth visit. In term of attitude, it was found that the mean scores for both groups increased with time. Mean score for knowledge and attitude is highest at the second visit which was immediately after the intervention. This shows that it is important for the students to have continuous intervention in order to ensure that the knowledge and attitude score remains high. As a conclusion, it was found that the counseling intervention programme helps to increase knowledge of the students but was found difficult to change their attitude in a short period of time. Close monitoring and continuous intervention help to increase knowledge and attitude towards smoking among adolescents.
Acupuncture for Sickle Cell Pain Management in a Pediatric Emergency Department, Hematology Clinic, and Inpatient Unit

Abstract Background: Acupuncture has been shown to mitigate certain painful conditions in children. However, utilization of acupuncture for addressing acute and chronic pain in children with sickle cell disease has not been well-studied. The aim of this article is to report the use of acupuncture to treat acute and chronic sickle cell pain in one patient in a pediatric emergency department (PED), hematology clinic, and inpatient unit of an inner-city children's hospital. Case: A 16-year-old Hispanic male with sickle cell disease was treated with acupuncture for 3 years. A retrospective chart review was performed to collect details on the acupuncture treatments, their effects on this patient's pain and anxiety, feedback from the patient and his family, and frequency of PED visits and admissions for pain. Results: Fifty-eight acupuncture treatments were administered for this patient's sickle cell pain during the period that was reviewed. His pain was reduced by an average of 2.3 points and 2.2 points for in.
Kinodynamic Motion Planning for Autonomous Vehicles

This article proposes a computationally effective motion planning algorithm for autonomous ground vehicles operating in a semi-structured environment with a mission specified by waypoints, corridor widths and obstacles. The algorithm switches between two kinds of planners, (i) static planners and (ii) moving obstacle avoidance manoeuvre planners, depending on the mobility of any detected obstacles. While the first is broken down into a path planner and a controller, the second generates a sequence of controls without global path planning. Each subsystem is implemented as follows. The path planner produces an optimal piecewise linear path by applying a variant of cell decomposition and dynamic programming. The piecewise linear path is smoothed by Bézier curves such that the maximum curvatures of the curves are minimized. The controller calculates the highest allowable velocity profile along the path, consistent with the limits on both tangential and radial acceleration and the steering command for the vehicle to track the trajectory using a pure pursuit method. The moving obstacle avoidance manoeuvre produces a sequence of time-optimal local velocities, by minimizing the cost as determined by the safety of the current velocity against obstacles in the velocity obstacle paradigm and the deviation of the current velocity relative to the desired velocity, to satisfy the waypoint constraint. The algorithms are shown to be robust and computationally efficient, and to demonstrate a viable methodology for autonomous vehicle control in the presence of unknown obstacles.
Testing component-based distributed applications

Applications that utilize the broker-based architecture are often composed of several components that need to be tested both separately and together. An important activity during testing is the assessment of the adequacy of test sets. Testers use one or more adequacy criteria for this activity. Traditional test adequacy criteria have several limitations for commercial use. Therefore, a set of scalable interface-based test adequacy criteria have been identified and a testing method that uses these criteria proposed. This method incorporates elements from a component's interface description for computing coverage using multiple test adequacy criteria and performing interface mutation and fault-injection testing. A prototype testing and monitoring tool that implements the proposed method is described. The proposed interface-based test adequacy criteria were evaluated empirically and compared with control flow-based coverage criteria for their relative effectiveness an revealing errors and the cost incurred in developing the test sets. A formal analysis of the fault-detection ability of the testing methods was also carried out. In addition to the assessment of test adequacy, testers often need to assess the tolerance of an application to failures in its components or in the environment. The interface-based testing method has been extended to allow for fault-injection testing at the component interfaces. Experimental results are reported for fault-injection testing on a client-server system. A generic set of faults is identified for use while testing broker-based systems.
"This is my thing!": Middle years students' engagement and learning using digital resources

It is widely acknowledged that multimodal digital texts support student engagement with ideas, knowledge and new forms of literate practice. With this in mind, an interdisciplinary team at The University of Melbourne collaborated to create a digitalresource – The Venom Patrol website – to teach scientific concepts about Australia’s venomous animals to middle years students (Years 5-9). The website’s development was a response to students’ increasing use of digital texts and technologies, and the need to develop students’ skills around being ‘multiliterate’. An inquiry-based pedagogy sought to encourage interactive learning and to enhance student development of scientific literacy. This article reports the findings of a pilot study that investigated student and teacher responses to the functionality and appropriateness of the digital resource for teaching scientific literacy, and for engaging students with the science-based content. The study revealed different teacher approaches to using the digital resource in the classroom, with varying levels of success. It also found the students to be critical and insightful users of digital texts who welcomed both the choices offered by the non-linear structure of the resource and the opportunity this research afforded for their voices to be heard around texts and contexts for learning.

Python-based Raspberry Pi for Hand Gesture Recognition

In this paper, a real time vision based system is proposed to monitor objects (hand fingers). It is built based on the Raspberry Pi with camera module and programmed with Python programming Language supported by Open Source Computer Vision (OpenCV) library. It also contains a 5 inch 800*480 Resistive HDMI Touch screen for I/O data. The Raspberry Pi embeds with an image-processing algorithm called hand gesture, which monitors an object (hand fingers) with its extracted features. The essential aim of hand gesture recognition system is to establish a communication between human and computerized systems for the sake of control. The recognized gestures are used to control the motion of a mobile robot in real-time. The mobile robot is built and tested to prove the effectiveness of the proposed algorithm. The robot motion and navigation satisfied with different directions: Forward, Backward, Right, Left and Stop. The recognition rate of the robotic system reached about 98.
Evaluation of HIV therapeutic agents on immunological, lipid and lipoprotein indices in Ghanaian HIV-1 infected patients

HIV-1 infected patients initiating antiretroviral therapy (ART) in Ghana are placed on one of the two most commonly used non-nucleoside reverse transcriptase inhibitors (NNRTIs), nevirapine (NVP) and efavirenz (EFV), in combination with a nucleoside reverse transcriptase inhibitor backbone of either combivir (CBV) or stavudine (d4T)/lamivudine (3TC). This study sought to evaluate the effect of these therapeutic agents on weight, immunological, lipid and lipoprotein changes as well as the atherogenic indices of Ghanaian HIV-1 infected patients. This observational study was carried out at the ART clinic of the Regional Hospital, Bolgatanga in the Upper-East region of Ghana from September 2008 to September 2009 comprising 61 HIV-1 infected patients who were initiated on NVP or EFV in combination with either CBV or d4T/3TC. Out of the 61 enrolled patients, 27(44.3%) were on NVP and 34(55.7%) were on EFV. Within the NVP group, 16 (59.3%) were on CBV and 11(40.7%) on d4T/3TC whilst the EFV group had 26(76.5%) on CBV and 8 (23.5%) on d4T/3TC. Percentage changes in lipid profile components comprising total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-c) and low density lipoprotein cholesterol (LDL-c) was assessed over the 12-month period. Percentage changes in atherogenic index expressed as TC/HDL-c and LDL-c/HDL-c was also estimated. NVP elicited a 10.2% increase in weight compared to EFV and this was associated with CBV combination use. EFV further elicited a 9.1% increase in TC, 1.2% increase in TG, 39.3% increase in LDL-c and a 4.1% increase in HDL-c which resulted in concomitant percentage increases in TC/HDL-c (22%) and LDL-c/HDL-c (47.3%). CBV as a NRTI component of EFV elicited a 4.3% increase in TC/HDL-c and a 16.6% increase in LDL-c/HDL-c compared to d4T/3TC whilst conversely, d4T/3TC elicited a 3.6% increase in TC/HDL-c and a 34.0% when used in combination with NVP. NVP combination therapy elicited improvement in weight compared to EFV combination therapy for the different categories of patients. The less atherogenic lipid profile observed in patients taking NVP in comparison to those taking EFV and the reduction in CHD risk associated with NVP + CBV combination therapy observed in this study should be factored into considerations taken when selecting the most appropriate ART regimen for treatment naive HIV-1 infected patients.Journal of Medical and Biomedical Sciences (2016) 5(3), 13-27Keywords: HIV-1, Antiretroviral therapy, Immunological, Lipids, Atherogenic indices, Bolgatanga, Ghana
A high heat flux IGBT micro exchanger setup

Much progress has been made over the past few years in the design of power electronic components leading to increasing development of IGBT transistors. Now IGBTs can dissipate power densities higher than 400 W/cm/sup 2/ and the thermal environment has become a major factor in their behavior. The aim of this paper is to demonstrate the high performance of a silicon microchannel setup. First, a thermal study enables the theoretical behavior of the setup to be analyzed. Then an optimization method based on genetic algorithms allows the determination of the best microchannels. Finally, the theoretical results are compared with experimental measurements.
The Effects of Education and Experience on the Attitudes of Pre-service Physical Educators toward Teaching Children with Disabilities

The education of children with disabilities has changed dramatically since 1970. Litigation and legislation have guaranteed students with disabilities a free and appropriate public education in an environment which would be least restrictive. This has placed some students with teachers who may not have a positive attitude toward teaching children with disabilities. Research has identified several variables which effect an educators' attitude toward teaching children with disabilitiesthe two most prominent being previous experience and education. The purpose of this study was to determine the effects of education and experience on the attitudes of pre-service physical education educators toward teaching children with disabilities. Pre-service physical educators from The College at Brockport, State University of New York, who were enrolled in an introduction to adapted physical education course, were asked to complete a modified version of the Physical Educators' Attitudes toward Teaching the Handicapped (PEA Ill) questionnaire before and after their experience in the course, which included field experience. Results indicated that there was no significant difference in the pre-service teachers' attitudes toward teaching children with disabilities before and after the course. Even though results were not significant, there was a trend toward pre-service attitudes becoming more favorable. The trend suggests that higher education institutions can create a positive and effective adapted physical education course in physical education teacher preparation courses that may increase positive attitudes. The lack of significance suggests that more can be done to continue to improve attitude.
Characterization of End-to-End Delays in Head-Mounted Display Systems

Primary motivation for this work was the desire to characterize the relative performance (in terms of measurement latency) of the various tracking technologies currently in use at the University of North Carolina in Chapel Hill (UNC-CH). Included in the test were four commercial magnetic trackers: two from Ascension Technology Corporation (the Ascension Bird and the newer Flock of Birds), and two from Polhemus Incorporated (the Polhemus 3Space Tracker and the 3Space Fastrak models). Also included in the test was UNC’s own Optical Ceiling Tracker. Note that both the Ascension Bird and the Polhemus 3 Space Tracker are older models and are no longer in production.
Soft tissue grafting and single implant treatment in the aesthetic region

Rehabilitation of a single failing or a single missing tooth in the maxillofacial aesthetic zone by either immediate single implant placement and provisionalization or conventional single implant treatment has been shown to be reliable treatment options. Both treatment procedures, in times of high aesthetic demands, have to deal with recession of the mid-buccal mucosa resulting in a less favourable aesthetic outcome, however. It is presumed that soft tissue grafting by increasing the volume of the mid-buccal mucosa might be beneficial for the aesthetic outcome. Therefore, the general aim of the research described in this thesis was to gain insight into the effect of soft tissue grafting on the condition and aesthetics of the peri-implant tissues in single implant treatment in the aesthetic zone. Single tooth rehabilitation with either immediate placement and provisionalization or conventional implant treatment showed excellent results for peri-implant tissues, aesthetics, patient satisfaction and survival, but with hardly any effect of soft tissue grafting. Connective tissue grafting in immediate single implant treatment compared to no soft tissue grafting resulted in less recession of the mid-buccal mucosal level, but did not contribute to a volume gain of the mid-buccal mucosa. Soft tissue grafting in conventional implant cases at implant placement in preserved alveolar ridges did not result in a more favourable aesthetic outcome, however.
