EFFECT OF STRAIN RATE ON THE TENSILE FAILURE OF GLASS-FIBRE BRAIDED TUBES

Tensile tests have been performed at up to five different displacement rates, from about lmm/s to over 20,000mm/s, on braided glass-fibre tubes of both square and circular cross-section and the corresponding force-displacement curves have been derived. In general both the maximum tensile force and the displacement at failure increase with increasing loading rate, implying a greater energy absorbing capability at the higher deformation rates. At all rates of loading the square cross-section tubes support a lower maximum force and fail at a higher overall deformation. Two stages in the failure process are considered, the realignment of the fibres against the resistance of the matrix followed by the tensile failure of the fibres. Both these processes are found to be rate dependent.
A Review of Multi-Class Classification for Imbalanced Data

Prediction and correct voting is critical task in imbalance data multi-class classification. Accuracy and performance of multi-class depends on voting and prediction of new class data. Assigning of new class of imbalance data generate confusion and decrease the accuracy and performance of classifier. Various authors and research modified the multiclass classification approach such as one against one and one against all. In both method OAO and OAA create a unclassified region for data and decrease the performance of classifier such as support vector machine. Some other method such as decision tree classifier, nearest neighbor and probability based classifier also suffered from imbalance data classification. In this paper we discuss various method and approach for multi-class classification for imbalance data.
A Structure-Based Approach for Detection of Thiol Oxidoreductases and Their Catalytic Redox-Active Cysteine Residues

Cysteine (Cys) residues often play critical roles in proteins, for example, in the formation of structural disulfide bonds, metal binding, and various catalytic functions. Thiol oxidoreductases, enzymes containing catalytic redox‐active Cys residues (redox Kat Cys), have been extensively studied, but even for these proteins there is little understanding of what distinguishes their redox Cys from other Cys functions. Herein, we characterized thiol oxidoreductases at a structural level and developed an algorithm that can efficiently recognize them by (i) analyzing amino acid and secondary structure composition of the active site and its similarity to known active sites containing redox Kat Cys, and (ii) calculating accessibility, active site location and reactivity of Cys. By applying this procedure to the Saccharomyces cerevisiae proteome, we could identify the majority of known yeast thiol oxidoreductases. This study provides insights into the structural properties of redox Kat Cys and highlights important differences between these residues and other reactive Cys. It should help recognize novel thiol oxidoreductases in structure databases.
Evaluation of Technology ImplementationImpact on Job Satisfaction

The present research tries to investigate technology impact on job satisfaction and recognition of organizational justice and technology understanding and individual differences (work conscience and adaptation). The research methodology is of correlation-descriptive type and is applied from objective type, the statistical population contains all Kuhdasht city municipality and its subsidiary units employees (92 people). According to Morgan table, 74 people were selected as sample size. Field data gathering was conducted by questionnaire and data analysis was based upon Likert 5-point scale from completely agree to completely disagree. Reliability was tested by CHronbach’s alpha to be 85 % for 45 questions. Regression was used to test the hypothesis in SPSS18. Results showed that organizational justice had positive impact on job satisfaction. Technology self-effectivityaffects job satisfaction along with perception of technology. Organizational justice along with technology self-effectivity does not affect perception of technology and also work conscience and adaptation does not affect perception of technology and job satisfaction.
Can Personality Type be Predicted by Social Media Network Structures

Social media platforms have become an integral part of how we live our lives, in particular for those generations who have grown up in the digital world and use these platforms to connect and communicate with many different groups. Personality profiling now underpins many facets of our lives for example digital marketing campaigns target specific audience groups using information gleaned from how a person engages with social media (Seung, 2012). Specific personal information that could assist with precise targeting might be helpful to those who want to interact with people via digital media. Psychological Type suggests we are predisposed to certain behaviors and preferences (Jung, 1921). Traditional methods of assessing personality include observation or psychometric questionnaires. Both methods have their benefits and drawbacks but what are the alternatives? Can the digital world and in particular, social media platforms, provide an alternative method? If a person’s digital personality footprint could be assessed by the way they engage in social media activity this information could be used to precisely target informative communications as well as product marketing campaigns (Maehle & Shneor, 2010). This paper presents a summary of initial work undertaken to explore the nature of structural patterns represented by an individual’s Psychological Type, as defined by their MBTI type and specific aspects of their social network data, as defined within the context of their Facebook connections and usage. Initial findings suggest that the virtual world is able to reflect personality differences that exist in the external world. Ongoing research is being undertaken to build on these initial findings.
Activation of Dendritic Cells through the Interleukin 1 Receptor 1 Is Critical for the Induction of Autoimmune Myocarditis

Dilated cardiomyopathy, resulting from myocarditis, is the most common cause of heart failure in young patients. We here show that interleukin (IL)-1 receptor type 1–deficient (IL-1R1−/−) mice are protected from development of autoimmune myocarditis after immunization with α-myosin-peptide(614–629). CD4+ T cells from immunized IL-1R1−/− mice proliferated poorly and failed to transfer disease after injection into naive severe combined immunodeficiency (SCID) mice. In vitro stimulation experiments suggested that the function of IL-1R1−/−CD4+ T cells was not intrinsically defect, but their activation by dendritic cells was impaired in IL-1R1−/− mice. Accordingly, production of tumor necrosis factor (TNF)-α, IL-1, IL-6, and IL-12p70 was reduced in dendritic cells lacking the IL-1 receptor type 1. In fact, injection of immature, antigen-loaded IL-1R1+/+ but not IL-1R1−/− dendritic cells into IL-1R1−/− mice fully restored disease susceptibility by rendering IL-1R1−/− CD4+ T cells pathogenic. Thus, IL-1R1 triggering is required for efficient activation of dendritic cells, which is in turn a prerequisite for induction of autoreactive CD4+ T cells and autoimmunity.
At the Crossroads: Racial and Womanist Identity Development in Black and White Women.

This study explored the hypothesis that womanist identity and racial identity development are related. The racial identiy and womanist identity attitudes of 214 women were measured using the Black Racial Identity Attitude Scale, the White Racial Identity Attitude Scales (WRIAS), and the Womanist Identity Attitude Scale. Canonical correlation analysis was used to determine the nature of relationships among racial identity and womanist identity attitudes. Results showed that for Black women there was a significant relation between racial identity and womanist identity attitudes. Specifically, Internalization attitudes on the WRIAS were positively related to Level II (Encounter) and Level IV (Internalization) attitudes on the Womanist Identity Attitude Scale. Despite a larger number of White participants, no such relationship emerged for White women. Implications for theory, research, and counseling are discussed.
Role of natural killer cells in antibacterial immunity

ABSTRACT Introduction: Bacteria are a significant cause of infectious complications, in particular in immunocompromised patients. There is an increasing understanding that Natural Killer (NK) cells not only exhibit direct activity against bacteria, but also exert indirect antibacterial activity through interaction with other immune cells via cytokines and interferons. Areas covered: This review seeks to give a global overview of in vitro and in vivo data how NK cells interact with bacteria. In this regard, the review describes how NK cells directly damage and kill bacteria by soluble factors such as perforin, the impact of NK cells on other arms of the immune system, as well as how bacteria may inhibit NK cell activities. Expert commentary: A better characterization of the antibacterial effects of NK cells is urgently needed. With a better understanding of the interaction of NK cells and bacteria, NK cells may become a promising tool to prevent or to combat bacterial infections, e.g. by adoptively transferring NK cells to immunocompromised patients.
Toxicity from the recreational use of 1-benzylpiperazine

Aim. This study describes the demographics and symptoms of patients, who presented to the Emergency Department (ED) in Christchurch, New Zealand, with toxicity from 1-benzylpiperazine (BZP)-based “party pills. ” BZP use has become widespread among the 16- to 30-year age group in New Zealand. This study explores the relationship between plasma BZP level and adverse effects experienced by users. The influence of ethanol co-ingestion was also studied. Methods. From 1 April 2005 to 1 July 2007, all BZP-related presentations to the ED were captured on a prospective data sheet. Patients were recruited to obtain plasma BZP levels, and these were correlated with the incidence of seizures and other symptoms. Coexistent ethanol use was also correlated with the frequency of seizures and other common BZP-induced symptoms. Results. In total 178 presentations with BZP toxicity were recorded. BZP levels were measured in 96. Sixty-nine percent of patients co-ingested other substances, with the most common substance being ethanol. In patients who ingested BZP alone, increased plasma BZP levels were associated with increased seizure frequency. Ethanol co-ingestion reduced the incidence of seizures, but significantly increased the likelihood of confusion and agitation. Conclusions. Adverse effects from BZP commonly include confusion, agitation, vomiting, anxiety, and palpitations. There is strong evidence that higher plasma levels of BZP are associated with an increased incidence of seizures. Co-ingestion of ethanol increases the likelihood of common and distressing BZP-induced symptoms but reduces the incidence of BZP seizures.

Mapping Tropical Dry Forest Succession With CHRIS/PROBA Hyperspectral Images Using Nonparametric Decision Trees

Most satellites for environmental monitoring point ground targets from a perpendicular position to the terrain, also known as nadir. The CHRIS/PROBA platform provides four extra angles of observation, plus nadir pointing: -55°, -36°, 0°, +36°, and +55°. The purpose of this study is to investigate the best season (wet or dry season) and angle of observation to map tropical dry forest succession in Brazil. Nonparametric decision trees were used to build up classification maps based on principal component analysis (PCA) inputs. Our results indicate that the use of off-nadir data improves the map accuracy of successional stages of tropical dry forests and riparian forests. Particularly, extreme and negative angles of observation generate higher map accuracies, suggesting that tree shadows are enhancing spectral differences between the studied vegetation classes. Images from the dry season provide better total and classes' map accuracies for late and intermediate stages of tropical dry forests. On the other hand, some classes, such as riparian forests and early stage of tropical forests need the use of off-nadir angles of observation to reach a minimum accuracy and best scores are reached using wet season's images.
Towards corporate confidentiality preserving auditing mechanisms for Clouds

IT services realized within cloud environments often suffer from a lack of transparency. On the one hand this opacity with respect to operational practices protects business secrets of a cloud provider. On the other hand, if services from critical infrastructures run within clouds this opacity becomes a severe problem, e.g., for a later root cause analysis in case of failures. This paper presents approaches for auditing the mapping of virtual resources to physical resources while preserving corporate confidentiality of the cloud providers. We also make sure that the resulting auditing information is useful for a later root cause analysis. Our research concludes that statistical binding and computational hiding commitment schemes are a suitable solution. Moreover, our approach enables a trusted third party to perform audits on behalf of tenants.
Global Regulation of Gene Expression by ArlRS, a Two-Component Signal Transduction Regulatory System of Staphylococcus aureus

ABSTRACT Staphylococcus aureus expresses various cell wall-associated and extracellular virulence factors, coordinately controlled by different two-component signal transduction systems and transcriptional regulators. In this study, we used microarray technology to identify the genes regulated by ArlR. The microarray data indicate that ArlR functions as a positive regulator and also as a negative repressor to directly and/or indirectly mediate the expression of at least 114 genes involved in different functions, including autolysis, cell division, growth, and pathogenesis.
Biochemical characterization of avirulent Agrobacterium tumefaciens chvA mutants: synthesis and excretion of beta-(1-2)glucan

The chvA gene product of Agrobacterium tumefaciens is required for virulence and attachment of bacteria to plant cells. Three chvA mutants were studied. In vivo, they were defective in the synthesis, accumulation, and secretion of beta-(1-2)glucan; however, the 235-kilodalton (kDa) protein known to be involved in the synthesis of beta-(1-2)glucan (A. Zorreguieta and R. Ugalde, J. Bacteriol. 167:947-951, 1986) was present and active in vitro. was present and active in vitro. Two molecular forms of cyclic beta-(1-2)glucan, designated types I and II, were resolved by gel chromatography. Type I beta-(1-2)glucan was substituted with nonglycosidic residues, and type II beta-(1-2)glucan was nonsubstituted. Wild-type cells accumulated type I beta-(1-2)glucan, and chvA mutant cells accumulated mainly type II beta-(1-2)glucan and a small amount of type I beta-(1-2)glucan. Inner membranes of wild-type and chvA mutants formed in vitro type II nonsubstituted beta-(1-2)glucan. A 75-kDa inner membrane protein is proposed to be the chvA gene product. chvA mutant inner membranes had increased levels of 235-kDa protein; partial trypsin digestion patterns suggested that the 235-kDa protein (the gene product of the chvB region) and the gene product of the chvA region form a complex in the inner membrane that is involved in the synthesis, secretion, and modification of beta-(1-2)glucan. All of the defects assigned to the chvA mutation were restored after complementation with plasmid pCD522 containing the entire chvA region.
Experimental recovery of intrinsic fluorescence and fluorophore concentration in the presence of hemoglobin: spectral effect of scattering and absorption on fluorescence

Abstract. The ability to recover the intrinsic fluorescence of biological fluorophores is crucial to accurately identify the fluorophores and quantify their concentrations in the media. Although some studies have successfully retrieved the fluorescence spectral shape of known fluorophores, the techniques usually came with heavy computation costs and did not apply for strongly absorptive media, and the intrinsic fluorescence intensity and fluorophore concentration were not recovered. In this communication, an experimental approach was presented to recover intrinsic fluorescence and concentration of fluorescein in the presence of hemoglobin (Hb). The results indicated that the method was efficient in recovering the intrinsic fluorescence peak and fluorophore concentration with an error of 3% and 10%, respectively. The results also suggested that chromophores with irregular absorption spectra (e.g., Hb) have more profound effects on fluorescence spectral shape than chromophores with monotonic absorption and scattering spectra (e.g., black India ink and polystyrene microspheres).
Adult schizophrenia with scholastic failure or low IQ in childhood. A preliminary report.

This study compares the school-record data of 29 schizophrenics, their siblings, and controls. It relates the school-record data for each proband with his age at first psychiatric hospitalization and the amount of time subsequently accumulated in institutions for the mentally ill. School failure in childhood does not distinguish preschizophrenics from controls but, within the preschizophrenic group, repeating probands differ from nonrepeating probands on several important measures. Since the two groups differ in the course of their schizophrenic illness, they may also differ in etiologic factors. The most striking result is that schizophrenics with low childhood IQs show an earlier onset and remain institutionalized significantly longer than schizophrenics with average IQs. The strength of the relationship between IQ and prognosis in schizophrenic illness has not been fully appreciated in the past.
A conserved role for a GATA transcription factor in regulating epithelial innate immune responses

Innate immunity is an ancient and conserved defense mechanism. Although host responses toward various pathogens have been delineated, how these responses are orchestrated in a whole animal is less understood. Through an unbiased genome-wide study performed in Caenorhabditis elegans, we identified a conserved function for endodermal GATA transcription factors in regulating local epithelial innate immune responses. Gene expression and functional RNAi-based analyses identified the tissue-specific GATA transcription factor ELT-2 as a major regulator of an early intestinal protective response to infection with the human bacterial pathogen Pseudomonas aeruginosa. In the adult worm, ELT-2 is required specifically for infection responses and survival on pathogen but makes no significant contribution to gene expression associated with intestinal maintenance or to resistance to cadmium, heat, and oxidative stress. We further demonstrate that this function is conserved, because the human endodermal transcription factor GATA6 has a protective function in lung epithelial cells exposed to P. aeruginosa. These findings expand the repertoire of innate immunity mechanisms and illuminate a yet-unknown function of endodermal GATA proteins.
Effects of the Medicare Alzheimer's Disease Demonstration on the use of community-based services.

STUDY QUESTION Did the Medicare Alzheimer's Disease Demonstration with its case management and community service waivers affect the use of community-based long-term care services among people with dementia and their primary caregivers? DATA SOURCES Baseline and periodic caregiver interviews. Measures include client and caregiver attributes and self-reported service use. STUDY DESIGN The demonstration randomly assigned voluntary applicants into treatment and control groups. Treatment group cases were eligible for case management and for up to $699 per month in community care benefits. The actual monthly entitlement varied among the eight demonstration communities due to regional cost and inflation adjustments over time. Analyses are for the year after enrollment. DATA COLLECTION Analyses are of cases surviving six months or more in the community after enrollment (n = 5,209). Cases received baseline and semi-annual assessments. PRINCIPAL FINDINGS The intervention of case management and community service reimbursement had a strong, consistent, and positive effect on the likelihood of using home care (including homemaker/chore services, personal care services, companion services) and adult day care. Treatment group clients were at least twice as likely as control group clients to be using any of the four community-based services. A similar, but less pervasive effect was achieved with caregiver training and support group participation. Reimbursement provided by the demonstration's Medicare waiver was generally not sufficient to exceed the level of control group service acquired through private payment. CONCLUSIONS Reimbursement levels within the demonstration may have enabled more individuals to purchase some services, but they were not sufficient to increase the average level of use over those in the control group. No consistent differences between demonstration models were found in service use likelihood or average use among users.
Transmission of common, public and confidential messages in broadcast channels with multiple antennas

We study the Gaussian multiple-input multiple-output (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the transmitter sends a common message to both the legitimate user and the eavesdropper. Moreover, the legitimate user receives a private message, which is desired to be kept hidden as much as possible from the eavesdropper. We obtain the entire capacity-equivocation region of the Gaussian MIMO wiretap channel. This region contains all achievable common message, private message, and private message's equivocation rates. This capacity-equivocation region is equal to the capacity region of a Gaussian MIMO broadcast channel where the transmitter sends a common message to both the legitimate user and the eavesdropper, a public message to the legitimate user on which there is no secrecy constraint, and a confidential message to the legitimate user which needs to kept perfectly secret from the eavesdropper.
Robust Silhouette Extraction Technique Using Background Subtraction

We propose a robust method to extract silhouettes of foreground objects from color video sequences. To cope with various changes in the background, the background is modeled as generalized Gaussian Family of distributions and updated by the selective running average and static pixel observation. All pixels in the input video image are classified into four initial regions using background subtraction with multiple thresholds, after which shadow regions are eliminated using color components. The final foreground silhouette is extracted by refining the initial region using morphological processes. We have verified that the proposed algorithm works very well in various background and foreground situations through experiments.
