    This study was undertaken to identify the relationship between multiple intelligences with preferred science teaching and science process skills. The design of the study is a survey using three questionnaires reported in the literature: Multiple Intelligences Questionnaire, Preferred Science Teaching Questionnaire and Science Process Skills Questionnaire. The study selected 300 primary school students from five (5) primary schools in Penang, Malaysia. The findings showed a relationship between kinesthetic, logical-mathematical, visual-spatial and naturalistic intelligences with the preferred science teaching. In addition there was a correlation between kinesthetic and visual-spatial intelligences with science process skills, implying that multiple intelligences are related to science learning

    : This aim of this research is to know (1) the differences of students\u27 motivation and achievement after using tapioca waste as learning resource in tenth grade, MAN 2 Pati in Archaebacteria and Eubacteria materials: (2) the effects of using tapioka waste as learning resources on students\u27 motivation and achievement in tenth grade, MAN 2 Pati. This research is quasi-experimental design with randomized control group, pre-post test. The study population was all students of Class X MAN 2 Pati, while the research sample is Class X-2 as the control group and Class X-3 as the experimental group. Data collection techniques were test and non-test techniques. The analyses used the t-test to determine differences in motivation and achievement. The results show that there is difference in learning motivation after using tapioca waste as a source of learning, indicated by the result of paired samples t-test, value of sig.(2-tailed)>α. There is no difference in learning achievement after using tapioca waste as a source of learning, which is indicated by paired sample t-test, the value of sig.(2-tailed)<α. Learning motivation and achievement of students who use tapioca waste as learning resources is higher than that of students who use the conventional learning resources

    Additional file 2. Successful expression of different P. falciparum antigen derived recombinant proteins in L. lactis. Purity profile of different target recombinant proteins as determined by SDS-PAGE analysis as shown by Coomassie blue staining (top panel) or Western Blot analysis (bottom panel) observed with anti-His antibody

    Additional file 1. Success rate of obtaining expression of target recombinant protein in L. lactis is not dependent on its biophysical characteristics. Success rate of expression of different target recombinant proteins in L. lactis have been grouped into High, Medium or Low depending on the yield of the respective expression. Yields show poor co-relations with the protein disorder score and presence of cysteine residues (a) and iso-electric point and the predicted molecular weight of the target recombinant proteins (b)

    Additional file 3. Anomalous migration by SDS-PAGE is related to protein disorder. Anomalous mobility was determined as the ratio between the apparent molecular weight as determined by SDS-PAGE and the molecular weight calculated from the deduced amino acid sequence (Table 1). Protein disorder was predicted using the IUPred software [41]. The protein disorder score was estimated by calculating the percentage of residues with a disorder score above 0.7

    Routing and quality of service in wireless and disruption tolerant networks

    Wireless networks have become a common means of communication, and their popularity continues to rise as they enable communication in locations and settings where it was previously unfeasible. While promising many advantages, these networks also pose new challenges. The limited radio coverage, unreliable nature of the wireless channel, and mobility of network nodes can lead to frequent disruption of communication links, dynamic network topology, variable bandwidth availability, and high channel error rates. These challenges seek novel solutions to allow a growing number of wireless, mobile users to run applications and avail network services in ways similar to that in wired networks. This thesis makes contributions to three research areas related to wireless and disruption tolerant networks: (1) routing and forwarding to enable disruption tolerant communication in intermittently connected networks, (2) analysis of properties of human mobility and their effect on network protocols in disruption tolerant networks, and (3) quality of service mechanisms for wireless and mobile networks. In intermittently connected networks, there may rarely or never exist a fully connected path between a source and destination. This invalidates the basic assumption of end-to-end communication prevalent in the Internet and renders traditional routing protocols impractical. We propose PRoPHET, a novel routing protocol for intermittently connected networks. PRoPHET takes advantage of the mobility of nodes, and the predictability of that mobility for routing. The protocol and various forwarding strategies and queueing policies are studied in detail. The benefits of PRoPHET are evident on comparing its performance with contemporary work. Communication in intermittently connected and disruption tolerant networks is often highly dependent on the mobility of the nodes in the network. Thus, it is important to have good understanding of basic properties of user mobility in order to design network protocols that can operate under those conditions. Using real-life traces, we characterize human mobility patterns and their impact on forwarding algorithms in mobile networks with and without infrastructure. Finally, the thesis presents our work on two different aspects of quality of service in wireless and mobile networks. We evaluate four mechanisms for providing service differentiation in a wireless LAN, and give recommendations on their use in different scenarios. We propose a novel admission control scheme for mobile ad hoc networks, which is able to better cope with high mobility in the network compared to previous solutions.Godkänd; 2006; 20061205 (haneit)</p

    <div><p><em>Plasmodium falciparum</em> malaria kills nearly a million people annually. Over 90% of these deaths occur in children under five years of age in sub-Saharan Africa. A neutrophil mediated mechanism, the antibody dependent respiratory burst (ADRB), was recently shown to correlate with protection from clinical malaria. Human neutrophils constitutively express Fc gamma receptor-FcγRIIA and FcγRIIIB by which they interact with immunoglobulin (Ig) G (IgG)-subclass antibodies. Polymorphisms in exon 4 of <em>FCGR2A</em> and exon 3 of <em>FCGR3B</em> genes encoding FcγRIIA and FcγRIIIB respectively have been described to alter the affinities of both receptors for IgG. Here, associations between specific polymorphisms, encoding FcγRIIA p.H166R and FcγRIIIB-NA1/NA2/SH variants with clinical malaria were investigated in a longitudinal malaria cohort study. FcγRIIA-p.166H/R was genotyped by gene specific polymerase chain reaction followed by allele specific restriction enzyme digestion. <em>FCGR3B</em>-exon 3 was sequenced in 585 children, aged 1 to 12 years living in a malaria endemic region of Ghana. Multivariate logistic regression analysis found no association between FcγRIIA-166H/R polymorphism and clinical malaria. The A-allele of <em>FCGR3B</em>-c.233C>A (rs5030738) was significantly associated with protection from clinical malaria under two out of three genetic models (additive: <em>p</em> = 0.0061; recessive: <em>p</em> = 0.097; dominant: <em>p</em> = 0.0076) of inheritance. The FcγRIIIB-SH allotype (CTG<b>A</b>AA) containing the 233A-allele (in bold) was associated with protection from malaria (<em>p</em> = 0.049). The FcγRIIIB-NA2*03 allotype (CTGCGA), a variant of the classical FcγRIIIB-NA2 (CTGCAA) was associated with susceptibility to clinical malaria (<em>p</em> = 0.0092). The present study is the first to report an association between a variant of FcγRIIIB-NA2 and susceptibility to clinical malaria and provides justification for further functional characterization of variants of the classical FcγRIIIB allotypes. This would be crucial to the improvement of neutrophil mediated functional assays such as the ADRB assay aimed at assessing the functionality of antibodies induced by candidate malaria vaccines.</p> </div
