Bluetooth scatternet formation and internetworking with 802.11 and GPRS

Mobile Ad-Hoc networks(MANET) using Bluetooth technology has gained immense popularity among the networking community. Nowadays electronic devices like cell phones come equipped with Bluetooth. Whereas Bluetooth technology has certain obvious advantages like low power consumption and reliable connection but it suffers some inherent problems including low area of operation, limit of 7 slave devices per master device. 802.11 technology on the other hand, has a wider area of operation and therefore very useful as Access points and higher bandwidth in the order of 11 Mbps in 802.11b. But 802.11 has a higher power consumption than Bluetooth. Cellular networks have a much wider coverage in geographical area than 802.11. Complementing Bluetooth with 802.11 and cellular network technology like GPRS would solve the shortcomings of these three technologies. This thesis is composed of four projects. It introduces RCBTEE(A Remotely Controlled Bluetooth Enabled Environment) which presents a simple Bluetooth Scatternet formation algorithm with remote control applications and a single access point connected to a content server. Then EquiBlue is presented. EquiBlue is a load balanced Bluetooth Scatternet formation algorithm. Then BlueFi is introduced. BlueFi presents a conceptual software layer in the protocol stacks of Bluetooth and 802.11 to realize interoperability in devices with both Bluetooth and 802.11 interfaces. At the end, BlueMobile, a novel protocol for handoff’s in Bluetooth, 802.11 and GPRS networks is presented. A thorough analysis of all the four projects is done and detailed simulation results are provided. The results underscore the importance of achieving convergence in Bluetooth networks with other networks like 802.11 and GPRS.
Insulation properties of nano- and micro-filler mixture composite

This paper presents the electrical insulation properties of a newly-developed composite material comprising a nano- and micro-filler mixture. The filler mixture composite was made by dispersing layered silicate fillers and silica fillers in epoxy resin. The filler mixture composite had the same low thermal expansion as aluminum. Moreover, comparison with other composites demonstrated the effects of the filler mixture. The filler mixture composite showed excellent insulation breakdown properties in needle-plate electrode geometry. Microscope observation indicated a densely-packed structure of the filler mixture composite. The morphological feature seems to have an impact on the improvement of insulation breakdown properties.
Adaptation and Evaluation of a Personal Electronic Nose for Selective Multivapor Analysis

The evaluation of a commercial, belt-mountable “electronic nose” modified for the rapid recognition and quantification of individual solvent vapors and simple vapor mixtures at low ppm concentrations is described. Marketed under the name VaporLab® this direct-reading instrument was designed for qualitative determinations of the presence or absence of selected individual vapors and was adapted in this study for quantitative determinations of vapors and vapor-mixture components. Vapor samples are concentrated on a small adsorbent bed and then thermally desorbed for analysis by an array of four polymer-coated surface acoustic wave sensors. Tests were performed with 13 organic solvent vapors individually and in selected binary, ternary, and quaternary mixtures at concentrations ranging from 0.1 to 12 times the respective American Conference of Governmental Industrial Hygienists' (ACGIH®) threshold limit value (TLV®). Pattern recognition analyses yielded a library of response patterns to which subsequent actual and virtual (i.e., Monte-Carlo simulated) samples were compared to assess performance. Limits of detection < 0.025 × TLV are achieved (based on the most sensitive sensors) for 0.25 L of preconcentrated air samples collected over a 2-min period. Individual vapors from different functional group classes can be recognized, quantified, and discriminated from other vapors with little error, and discrimination of the components of binary mixtures is possible where the component vapor response patterns are sufficiently different. Within-class individual vapor and binary-mixture discriminations are more difficult and most ternary and higher-order mixtures could not be analyzed with acceptable accuracy. Changes in ambient humidity have no effect on responses and changes in temperature lead to well-behaved and compensable changes in responses. Tests of fluctuating concentrations demonstrate the capability for accurately tracking short-term variations in exposure. Overall, results suggest that this instrument could serve effectively as a personal exposure monitor in previously characterized occupational environments with proper revisions in design.
Authentic leadership, creativity, and innovation: A multilevel perspective

This study aims to propose and empirically test a multilevel model of cross-level interactions between authentic leadership and innovation at the team level, and perception of support for innovation and creativity at the individual level. We use data from 23 team leaders and 289 team members in a Slovenian manufacturing and processing firm engaged in producing innovative products and customer solutions and conduct a multilevel analysis using hierarchical linear modelling (HLM). The results indicate that whereas perceived team leaders’ authentic leadership directly influences team members’ individual creativity and team innovation, the impact of self-ascribed team leaders’ authentic leadership was not significant. In addition to that, the relationship between team leaders’ authenticity and creativity is mediated by perception of support for innovation. Using a multilevel approach, this is the first study to our knowledge to quantitatively examine the relationship between authentic leadership and creativity and innovation. In addition, unlike previous research on related topics that relied solely on one source of information, we examine authentic leadership with empirical data gathered from both team leaders and their employees.
Type I neurofibromatosis: a geno-oculo-dermatologic update

Purpose of review This review will focus on the recent clinical insights into type I neurofibromatosis (NF1), the most common geno-oculo-dermatosis. Advances in the treatment will also be reviewed. Recent findings NF1 shares phenotypic features with disorders such as Legius syndrome, type 2 neurofibromatosis (NF2), and multiple lentigenes syndrome. Molecular diagnostic testing aids in diagnosing young children with still-evolving clinical signs and distinguishes NF1 from these other conditions. The management of optic pathway gliomas (OPGs) remains controversial. OPGs may enlarge in later childhood and beyond such that longer ocular surveillance may be appropriate. Retinal nerve fiber layer thickness inversely correlates with OPGs and decreased vision. There is suspected correlation of cerebral arteriopathy risk with the presence of OPGs. Ciliary body cysts and retinal pigmentary abnormalities may also be markers of NF1. Studies continue to confirm the utility of Lisch nodules as a diagnostic marker in older children and adults and seem to correlate with underlying iris pigmentation and sunlight exposure. Promising therapies are being developed based on NF1's central role in the RAS/RHEB/mTOR signal transduction pathway. Summary Continuing advances are enhancing the diagnosis and management of NF1. Current clinical trials use agents that target the RAS/mTOR signal transduction pathway and alter microenvironmental factors that contribute to tumor progression.
A Study on the Healing‐over of Myocardial Cells of Toads

The possible role of the intercellular junctions on the sealing process of toad myocardium was investigated in preparations immersed in hypertonic sucrose solutions and in solutions containing EDTA, both of which caused the separation of many intercalated disks and of a large number of cells. The rate of healing was determined by measuring the amplitude of the injury potentials as a function of time. The potential differences were recorded with the “roving” electrode technique immediately after injury and then at 2-minute intervals. Measurements made in preparations immersed in normal Ringer's solution showed that the depolarization caused by a lesion was totally reversed in 10 to 12 minutes. In muscles immersed in hypertonic sucrose solutions for 20 minutes, a marked reduction of the rate of healing was observed. Similar results were obtained with EDTA (2.5 mM) or with Ca2+-free solutions. The effect of hypertonic solutions was not counteracted by the addition of 10 mM Ca2+ to the solution. The results suggest that the integrity of the intercellular junctions is essential for the healing process.
Anti-cardiolipin from periodontitis patients induces MCP-1 production by human umbilical vein endothelial cells.

AIM Periodontal diseases are associated with a variety of systemic diseases, including cardiovascular disease and stroke, and patients with periodontitis demonstrate elevated levels of anti-cardiolipin antibodies. We sought to determine if anti-cardiolipin antibodies from periodontitis patients induced monocyte chemotactic protein-1 production by human vascular endothelial cells. MATERIALS AND METHODS IgG was purified from sera from 53 subjects, including chronic and aggressive periodontitis patients and periodontally healthy controls, with elevated or normal IgG anti-cardiolipin levels. In addition, anti-cardiolipin antibodies were specifically removed from some sera by immunoabsorption. RESULTS We found that, irrespective of diagnostic category, IgG from subjects with elevated anti-cardiolipin induced significantly greater monocyte chemotactic protein-1 production by human vascular endothelial cells than IgG from those subjects with normal anti-cardiolipin titres. Removal of anti-cardiolipin from IgG preparations from periodontitis patients significantly reduced their ability to induce monocyte chemotactic protein-1. CONCLUSIONS Since elevated titres of anti-cardiolipin are found in a significantly greater proportion of patients with periodontitis than in periodontally healthy individuals, and these antibodies activate endothelial cells to produce monocyte chemotactic protein-1, they may explain some of the associations noted between periodontal infections and systemic conditions.
Use of Chronic Kidney Disease to Enhance Prediction of Cardiovascular Risk in Those at Medium Risk

Based on global cardiovascular (CV) risk assessment for example using the Framingham risk score, it is recommended that those with high risk should be treated and those with low risk should not be treated. The recommendation for those of medium risk is less clear and uncertain. We aimed to determine whether factoring in chronic kidney disease (CKD) will improve CV risk prediction in those with medium risk. This is a 10-year retrospective cohort study of 905 subjects in a primary care clinic setting. Baseline CV risk profile and serum creatinine in 1998 were captured from patients record. Framingham general cardiovascular disease risk score (FRS) for each patient was computed. All cardiovascular disease (CVD) events from 1998–2007 were captured. Overall, patients with CKD had higher FRS risk score (25.9% vs 20%, p = 0.001) and more CVD events (22.3% vs 11.9%, p = 0.002) over a 10-year period compared to patients without CKD. In patients with medium CV risk, there was no significant difference in the FRS score among those with and without CKD (14.4% vs 14.6%, p = 0.84) However, in this same medium risk group, patients with CKD had more CV events compared to those without CKD (26.7% vs 6.6%, p = 0.005). This is in contrast to patients in the low and high risk group where there was no difference in CVD events whether these patients had or did not have CKD. There were more CV events in the Framingham medium risk group when they also had CKD compared those in the same risk group without CKD. Hence factoring in CKD for those with medium risk helps to further stratify and identify those who are actually at greater risk, when treatment may be more likely to be indicated.
High Resolution Topography of Age-Related Changes in Non-Rapid Eye Movement Sleep Electroencephalography

Sleeping brain activity reflects brain anatomy and physiology. The aim of this study was to use high density (256 channel) electroencephalography (EEG) during sleep to characterize topographic changes in sleep EEG power across normal aging, with high spatial resolution. Sleep was evaluated in 92 healthy adults aged 18–65 years old using full polysomnography and high density EEG. After artifact removal, spectral power density was calculated for standard frequency bands for all channels, averaged across the NREM periods of the first 3 sleep cycles. To quantify topographic changes with age, maps were generated of the Pearson’s coefficient of the correlation between power and age at each electrode. Significant correlations were determined by statistical non-parametric mapping. Absolute slow wave power declined significantly with increasing age across the entire scalp, whereas declines in theta and sigma power were significant only in frontal regions. Power in fast spindle frequencies declined significantly with increasing age frontally, whereas absolute power of slow spindle frequencies showed no significant change with age. When EEG power was normalized across the scalp, a left centro-parietal region showed significantly less age-related decline in power than the rest of the scalp. This partial preservation was particularly significant in the slow wave and sigma bands. The effect of age on sleep EEG varies substantially by region and frequency band. This non-uniformity should inform the design of future investigations of aging and sleep. This study provides normative data on the effect of age on sleep EEG topography, and provides a basis from which to explore the mechanisms of normal aging as well as neurodegenerative disorders for which age is a risk factor.
Comparison of ramosetron and ondansetron for control of post-operative nausea and vomiting following laparoscopic cholecystectomy.

BACKGROUND Post-operative nausea and vomiting (PONV) is common. 5HT 3 receptor antagonists are commonly used drugs for its prevention. A study was designed to compare the efficacy and safety of ramosetron and ondansetron in patients undergoing laparoscopic cholecystectomy (lap chole). MATERIALS AND METHODS A prospective randomized case controlled study was conducted at J. N. Medical College Hospital, Aligarh Muslim University, Aligarh, India, in patients who underwent lap chole following intravenous administration of ondansetron (4mg) or ramosetron (0.3mg) at the end of surgery, and efficacy as well as side effects of ondansetron and ramosetron was documented and compared. RESULTS One hundred and thirty adult females undergoing lap chole were studied - 65 patients in each of the two groups. In first 24 h after surgery, complete response (No PONV) was observed in 28 patients of the ondansetron group and in 32 patients of the ramosetron group (P>0.05). Complete response in the second 24 h after surgery was observed in 30 patients of the ondansetron group and in 45 patients of the ramosetron group (P<0.05). During the first and second 24 h, PONV requiring rescue antiemetic was significantly higher (P<0.05) in the ondansetron group as compared to the ramosetron group. Adverse drug effects in the post-operative period were observed in 11 and 8 patients in ondansetron and ramosetron groups respectively (P>0.05). CONCLUSION Ramosetron was found safe and more effective antiemetic than ondansetron in patients undergoing lap chole.
Tuning Gene Expression in Yarrowia lipolytica by a Hybrid Promoter Approach

ABSTRACT The development of strong and tunable promoter elements is necessary to enable metabolic and pathway engineering applications for any host organism. Here, we have expanded and generalized a hybrid promoter approach to produce libraries of high-expressing, tunable promoters in the nonconventional yeast Yarrowia lipolytica. These synthetic promoters are comprised of two modular components: the enhancer element and the core promoter element. By exploiting this basic promoter architecture, we have overcome native expression limitations and provided a strategy for both increasing the native promoter capacity and producing libraries for tunable gene expression in a cellular system with ill-defined genetic tools. In doing so, this work has created the strongest promoters ever reported for Y. lipolytica. Furthermore, we have characterized these promoters at the single-cell level through the use of a developed fluorescence-based assay as well as at the transcriptional and whole-cell levels. The resulting promoter libraries exhibited a range of more than 400-fold in terms of mRNA levels, and the strongest promoters in this set had 8-fold-higher fluorescence levels than those of typically used endogenous promoters. These results suggest that promoters in Y. lipolytica are enhancer limited and that this limitation can be partially or fully alleviated through the addition of tandem copies of upstream activation sequences (UASs). Finally, this work illustrates that tandem copies of UAS regions can serve as synthetic transcriptional amplifiers that may be generically used to increase the expression levels of promoters.
Improving a Family’s Overall Quality of Life Through Parent Training in Pivotal Response Treatment

As the diagnoses of autism in young children continually increase, the need for families to have access to research-based treatment models that are effective and efficient has become clear. Current research demonstrates the demand for parent-delivered behavioral interventions. The aim of this single-case study, conducted as part of an integrated Masters in Education/Special Education Credential Program, was to examine the relationship between one parent trained in pivotal response treatment (PRT), her implementation of PRT techniques, and the correlated gains of behavioral compliance in her 6-year-old boy with high-functioning autism (HFA). Visual analysis of collected data as well as calculation of nonoverlapping data points suggest that a parent, when effectively trained, can utilize PRT to increase the rate of behavioral compliance of his or her own children.
ACES - Application Cloud for Embedded Systems

As clouding computing emerges and brings new paradigms in the development and deployment of software, an inevitable issue would be the deployment and the execution of existing application software, not necessarily legacy ones, in an environment of cloud computing. The issue becomes even more challenging in satisfying users of embedded system products due to the characteristics of resource limitation and platform variety of such products. This paper presents an application cloud system, namely ACES (short for Application Cloud for Embedded Systems), which would be an effective approach to offloading the execution of applications from embedded system platforms to the cloud and helps transit to cloud computing. ACES allows existing applications, which are not developed for cloud computing, to be deployed on the server side in a cloud computing environment and to be executed, through operating a browser, from embedded system platforms on the client side. There is no need either to modify or to port the existing applications in the deployment. Neither is there any plug-in support required for the browser used. An implementation of ACES, of which X window applications are selected to be the existing applications, is described in this paper. It serves as an example to demonstrate how ACES works.

How Children Solve Environmental Problems: Using computer simulations to investigate systems thinking

Two computer simulations were developed and used to investigate systems thinking and environmental problem solving in children. Ninety-two primary school children (aged 8 years and 11 years) interacted with computer simulation of either a deforestation problem or a water depletion problem. The children's task was to manipulate the simulation thereby enabling it to run for as long as possible before resources—water or trees—were exhausted. This could be achieved via a number of strategies and their use by the two groups of children was compared. Through efficient use of resources and recycling strategies, the older children outperformed the younger children. Magical thinking was more prevalent among the 8-year-olds. The results also suggest that seemingly isomorphic environmental problems may not be interpreted as such.
Penyediaan dan pencirian filem komposit polikaprolakton terisi kanji ubi kayu

This research was conducted to develop a new biodegradable polymeric packaging material to replace the current polymer packaging without changing the requirements properties. Polycaprolactone (PCL) was chosen as the matrix because of its biodegradability characteristics. Tapioca starch was used as filler from 10 to 40 wt% loading contents. The composite films were prepared using solvent casting technique and chloroform was used as solvent to dissolve the PCL pellets. The PCL matrix showed result of higher tensile strength which was 65.9 N/mm with elongation at break at approximately 731%. The addition of starch in the PCL composite films increased the tensile modulus of the films. The tensile strength of the composite films decreased with increasing starch contents. Similar trends were also observed for elongation at break of the films.
