Influence of low – structure carbon black on the electrical, rheological and mechanical properties of graphite nanoplatelets/ethyl butyl acrylate composites

The semiconductive layers employed for manufacturing power cables are typically composed of a polymer matrix filled with conductive fillers. The aim of this work has been to assess the influence of the filler loadings into a polymer matrix, ethyl butyl acrylate (EBA), such as low – structure carbon black (LS – CB) and exfoliated graphite nanoplatelets (GNPs) GNP not xngp, on the electrical, rheological and mechanical properties of the composite. The attention was focused on a possible synergistic effect between the fillers, in order to create hybrid systems (characterized by GNP/LS – CB repartitions of 80/20, 70/30 and 60/40) with enhanced properties. Electrical, rheological and mechanical (uniaxial tensile) tests were performed on specimens extruded at 2 mm/min or 20 mm/min, with the hybrids showing an increased electrical conductivity and tensile modulus of the composite with an increasing filler volume content. The electrical percolation threshold was in most cases lower for the hybrid systems than for the pure GNP – EBA system, although the rheological percolation threshold increased slightly (as suggested by the behavior of the storage modulus as a function of the frequency (Hz) used during the dynamic tests). A microstructural analysis using SEM (Scanning Electron Microscope) revealed an orientation of the filler particles given by the extrusion which, when performed at higher speed (20 mm/min), also affected the electrical conductivity and the tensile modulus (MPa), both decreasing. The tensile modulus results were also analyzed in terms of the Nielsen and Halpin – Tsai models, whose performances were compared at a fixed tensile modulus of the filler . The main attention was paid to the Nielsen fitting model, which appeared to provide a better prediction of the experimental results.
Potential Protective Effects of Blackberry and Quercetin on Sodium Fluoride-inducedImpaired Hepato-renal Biomarkers, Sex Hormones and Hematotoxicity in Male Rats

Aim: The present study was carried out to evaluate the potential protective role of blackberry juice (BBJ) and quercetin (Q) against sodium fluoride-induced liver damage and impairment of kidney function, as well as hematotoxicity in rats. Study Design: After 2 weeks of acclimation, animals were divided into seven groups, ten rats each. All the groups were treated interaperitoneal (i.p.) for 30 successive days. Group 1 served as untreated control and received 1ml/Kg of distilled water i.p. daily. Group 2 was given i.p. BBJ at a dose of 1.6g/kgb.wt. containing 5mg anthocyanin. Group 3 was given quercetin at dose of 75mg/Kgb.wt. Group 4 was treated with 10.3mg/kg b.wt of NaF. Group 5 was given i.p. BBJ followed by NaF at the same doses. Group 6 was given quercetin followed by NaF and finally group 7 was treated with BBJ and Q then followed by NaF as mentioned previous doses. Methodology: Some hematological parameters were determined. Serum aspartate transaminase, alanine transaminase and alkaline phosphatase activities were as well as Original Research Article Ismail et al.; JALSI, Article no. JALSI.2014. 001 2 lipid profile and total protein were evaluated as biomarkers for liver functions. The levels of uric acid and creatinine in serum were estimated. Hormones of testosterone and inhibin B were assessed. Results: Sodium fluoride (NaF) caused an elevation in serum transaminases and alkaline phosphatase and reduced serum total protein, testosterone, and inhibin-B levels as well as levels of uric acid and creatinine, and induced hematotoxicity. It increased all the parameters of lipid profile except the high density lipoprotein cholesterol level was decreased. The presence of Q or BBJ with NaF successfully mitigated liver and kidney functions, which was more pronounced with Q. Conclusion: It can be concluded that concomitant administration of Q or BBJ with NaF may be useful in reversing the toxicity of NaF in male rats.
SEGMENTAL THORACIC SPINAL ANAESTHESIA FOR CHOLECYSTECTOMY - A CLINICAL TRIAL

AIM OF STUDY: Cholecystectomy is generally performed under general anaesthesia but regional anaesthesia has been found beneficial, especially in patients with major medical problems. The objective of this study was to evaluate the effectiveness of segmental spinal anaesthesia in cholecystectomy so that it can be later used in patients when general anaesthesia is not feasible. MATERIALS AND METHODS : Twenty patients of ASA I and II of either sex undergoing elective cholecystectomy received a segmental spinal anaesthesia at 10 th thoracic interspace (T 10 - T11 ) using 1.0 ml bupivacaine heavy (5 mgml -1) mixed with 0.5 ml fentanyl (25 μg). An epidural catheter was placed in the same space. Intraoperative haemodynamic parameters were monitored. Systemic drugs were administered if patients complained of pain, anxiety, hypotension, nausea or pruritus during or after surgery. RESULTS : The block was effective for surgery in all patients except two who required epidural top up. Four patients required midazolam for anxiety and five required mephenteramine for hypotension at two minutes after spinal injection, otherwise haemodynamics and respiratory parameters were within physiological limits. Twelve patients complained of mild pruritus around face and neck which did not require any treatment. Fifteen patients were able to ambulate after surgery. There was good surgeon and patients' satisfaction. CONCLUSION : Segmental Spinal Anaesthesia with bupivacaine and fentanyl could be a safe and effective alternative anaesthetic regime for cholecystectomy. However this technique requires great caution as the needle is inserted above the level of termination of the spinal cord and more studies with more number of cases are required befor advocating this technique.
Culturally Relevant Science: A Multiple Case-study on the Beliefs, Experiences and Practices of Pre-Service Teachers in Racially and Ethnically Diverse Classrooms

The latest report from the National Center for Education Statistics, indicates that the number of students from diverse racial and ethnical backgrounds continues to increase in United States' classrooms. These demographic changes have propelled revisions to current teacher education programs, in an effort to address the needs of all students. Students from underrepresented minorities do not perform as well as their counterparts in standardized assessments. This gap is observed across different grade levels and in all subjects, particularly science. Additionally, minority students are less likely to pursue careers in the STEM fields. The purpose of this multiple case-study was to investigate the beliefs, experiences and practices of seven pre-service science teachers in racially and ethnically diverse classrooms. The participants were part of a cohort from two national fellowships aimed at preparing science teachers to teach in high-needs' school districts. This study explored pre-service teachers' beliefs as related to racially and ethnically diverse learners in the science classroom. Additionally, this study investigated how these pre-service teachers conceptualized the tenets of Culturally Relevant Pedagogy and implemented these during their practice. Data was collected in the form of semistructured pre and post interviews, artifacts and field observations. An analysis of the preinterview data suggests that most of the participants believe that there is no difference in the way students from different racial/ethnical backgrounds learn science. The participants, however, agree that these students will require different levels of support for language and other skills. Conversely, a deficit view is still portrayed in some of their responses, specifically when they indicate that students’ background knowledge may be limited due to previous schooling experiences. An analysis of the data from artifacts and field observations indicates that most of the strategies used by the participants resemble efforts towards promoting academic success. Additionally, a significant number of activities used by the participants aimed at connecting the cultural aspect of students’ lives with the science content. However, the frequency of the indicators within the last tenet, critical consciousness, suggests that limited approaches were implemented by the participants within this area.

Enzymatic and proteomic analysis of spinal cord in a G93A ALS mouse model

Mutations to copper,zinc superoxide dismutase (Cu,Zn SOD or SOD1) are the only known causes of amyotrophic lateral sclerosis (ALS), a neurodegenerative disorder characterized primarily by death of spinal motor neurons. While the molecular mechanisms responsible for motor neuron death in this disease remain to be elucidated, recent studies implicate mitochondrial dysfunction as a key factor in the pathogenesis of ALS. In support of this, we observed ALS-dependent alterations in key functions including creatine kinase activity and ATP levels, which could be linked to changes in the mitochondrial proteome. Importantly, extensive research efforts have failed to develop a treatment that significantly delays onset of the disease or extends lifespan in individuals afflicted with ALS. Studies presented in this dissertation demonstrate that Motexafin Gadolinium (MGd), an organometallic compound, markedly extends survival in G93A mice, a well-established, standardized mouse model of ALS used to elucidate molecular mechanisms of disease and the efficacy of proposed new therapeutic treatments for ALS. Although the molecular mechanism responsible for the neuroprotection afforded by MGd is not known, we observed significant drug-related alterations to the proteome, which we propose may play a role in extending life span through normalization of protein expres-
Immunochromatographic Testing Method for Hepatitis B, C in Blood Donors

Background: Hepatitis is an inflammatory condition of the liver and viral hepatitis is a conventional term used to denote hepatitis caused by hepatotrophic viruses (Hepatitis A-G). High prevalence of these viruses are reported in Nigeria. Hepatitis B and C may cause liver cirrhosis and they can be contacted through contaminated blood and blood products. Many blood banks in Nigeria screen for hepatitis B and C using immune-chromatographic screening method (Rapid test strip). This is because these strips are readily available in the market, cheap, requires no electricity for storage, special training or equipment before use. The intent of our study is to compare the sensitivity of this method using an advanced immunological method. Method: 660 potential donors are tested for hepatitis B surface antigen (HBs Ag) and hepatitis C virus antibody using immune-chromatographic test strip and ELISA methods. Result: We found out that 38 (5.7%) out of 660 subjects tested positive for HBS Ag using immunochromographic method while 71 (10.8%) were positive using ELISA. None is positive for hepatitis C antibody using immunochromatographic method while 4 (0.6%) subjects were positive using ELISA method. Conclusion: Immunochromatographic method is not good enough to screen blood donors for hepatitis B and C.
The New Technology: The Consumer as Participant Rather than Target Audience

We need not to be let alone. We need to be really bothered once in a while. How long is it since you were really bothered? About something important, about something real? – Ray Bradbury Introduction New communication technologies and the emergence of what is being called ''Web 2.0'' are providing the opportunity for health promotion professionals to truly engage with their patients, customers, and audiences in ways unimaginable just a few years ago. Some of the more recent applications include: text messaging and mobile telephones for educational interventions to reduce sexually transmitted diseases among teenagers; interactive and entertaining health websites such as VERB and Whyville; sites where people with medical conditions can seek, give, and receive advice from other patients and healthcare providers (Organized Wisdom); and blogs of all descriptions hosted by health professionals, commercial entities, patients and advocates, and CEOs of healthcare organizations. Yet, these innovations have barely scratched the surface of the potential for these new technologies. What is underappreciated by many social marketers who are beginning to experiment with these new technologies is that they are not simply new types

Attributions of aggressive and nonagressive African-American male early adolescents: A study of construct accessibility.

This study proposed that aggressive and nonaggressive children might differ in the readiness with which biased causal beliefs are accessed from memory and used as guides to interpersonal judgment. Aggressive and nonaggressive African-American male early adolescents were randomly assigned to a condition that primed the perception of negative outcomes as intentionally caused or unintentionally caused or to a no-priming control condition. Participants then read a description of hypothetical peer provocation, and they made inferences about the peer's intent, the amount of blame and anger, and the likelihood of aggressive retaliation. In the unintentional and control conditions, aggressives made more extreme judgments than nonaggressives. In the intentional priming condition, the judgments of aggressives and nonaggressives were equally extreme
Indian Dental Students’ Perspectives on Dental Education and Their Future Professional Career: A Cross-Sectional Questionnaire Based Survey

Objectives: Investigating career intentions of dental students provides a better understanding of their role in society and contributes to the debate on existing dental education and practice. As an emerging workforce, they have very different professional expectations than those who are already in professional authority and also leading in practice. The objective of this study was to investigate Indian dental students’ perceptions on their career decisions after completing a Bachelor of Dental Surgery (BDS). Methods: A cross-sectional survey was carried out among third year and final year dental students; interns and fresh graduates from two Dental Educational Institutions in Davangere city, Karnataka, India. A validated close ended questionnaire was administered to 528 subjects. Results: The response rate was 82.19%. Of the 434 respondents, 40.8% have plans for preparing Original Research Article Ramesh et al.; BJESBS, 7(3): 211-219, 2015; Article no.BJESBS. 2015.085 212 for the Post-Graduate entrance exam after their Bachelor degree. Around 51.2% stated future earnings as the most important factor that influences the career choice after BDS. About 55.5% feel that the hands-on experience and overall training provided in the curriculum is not sufficient. Conclusion: Career related aspirations and intentions varied widely among the participants. Discontent regarding duration of the curriculum, overall training experience and earnings was evident from the study. Policy makers should consider revising the curriculum to tailor the needs of the students so that these obstacles would not affect the provision of oral health care.
The Personality Construct of Hardiness, IV

Personality hardiness has emerged as a composite of the interrelated attitudes of commitment, control, and challenge that provides the existential courage and motivation to turn stressful circumstances from potential disasters into growth opportunities. This study contributes to the construct validity of the latest measure of hardiness, the Personal Views Survey III—R (PVS III-R). In a large sample of undergraduates, the PVS III-R measure of hardiness showed adequate internal consistency reliability, the expected intercorrelation of components, and the absence of relationship to socially desirable responding. Furthermore, as expected, hardiness was negatively related to depression, anxiety, and hostility, even though it was also negatively related to avoidance of intrusive, stressful thoughts. Also as expected, hardiness was associated with positive attitudes toward school, instructors, and one's own capabilities and standards as well as expressed satisfaction with life. This pattern of results fits well with those of previous construct-validational studies of hardiness.
Counselor training level and the formation of the psychotherapeutic working alliance.

To investigate the relation of training level to working alliance, 50 counselor-client dyads from three counseling agencies were surveyed. Counselors were grouped into three training levels: (a) novices, in their first practicum; (b) advanced trainees, in their second practicum through predoctoral internship; and (c) experienced counselors, postdoctoral staff at the agencies. After the third session, counselors and clients completed the Working Alliance Inventory to provide ratings of the bond, task, and goal dimensions of their alliances
The problem of conventionality in the development of creole morphological systems

This paper focuses on the problem of the conventionalization of grammatical morphology during language formation, asking how a form comes to have a shared grammatical meaning in an emerging linguistic community. Results from an experiment, inspired by changes in the use of space in Nicaraguan Sign Language, are presented that demonstrate the difficulty of conventionalization for grammatical forms. We show that even in cases where meaning should be relatively easy to discern, adult listeners are not consistent, either internally or when compared to each other, in the inferences they draw. The paper ends with a discussion of the nature of the problem with respect to emerging languages more broadly, and speculates on how grammatical forms might come to have shared meanings in a newly emerging language, focussing on the role that children might play in the process.

Beden Eğitimi Öğretmen Adaylarının Bilişötesi Öğrenme Stratejileri, Akademik Öz-Yeterlikleri ve Öğretmenlik Mesleğine Yönelik Tutumları

The purpose of this study was to analyze metacognitive learning strategies and academic selfefficacy perceptions of pre-service physical education (PE) teachers and their attitudes towards the profession of teaching according to some demographic variables, and to determine the relationship between these variables. This study was conducted on 610 pre-service PE teachers. The Metacognitive Learning Strategies Scale (MLSS), the Academic Self-Efficacy Scale (ASES) and the Teaching Profession Attitude Scale (TPAS) were administered on the participants. Descriptive statistical methods, t test, MANOVA, ANOVA and correlation analysis were used in the data analysis. Whereas significant difference was not found in the values of academic self-efficacy beliefs and attitudes toward teaching profession based on gender, significant differences were found in between some of the subscales of the MLSS. The scores of the female pre-service PE teachers were higher than male participants, and the scores of the participants from the MLSS, the ASES and the TPAS did not differ significantly regarding their grade levels. Additionally, significant positive correlations were observed between the scores of the MLSS, the ASES and the TPAS.
Recent advances in navigation-assisted musculoskeletal tumor resection

The techniques of surgical navigation to assist with various orthopaedic operations have been improving and are becoming more frequently described. The applications of this technology in orthopaedic oncology are currently being investigated, and case reports are seen in the literature with increasing frequency, making this a technology with which orthopaedic oncologists should become familiar. Although there are a number of potential applications for navigation systems in orthopaedic oncology, currently there are a number of limitations as well. Benefits that can be envisioned include but are not limited to improving the precision of a planned resection or precisely matching a reconstruction to a resection defect. Current limitations include the lack of a software system that incorporates all the functionality that an orthopaedic oncologist could use and a mechanism to define accuracy of a resection. Future directions include the potential development of navigation systems that work together with implant design systems, or with robotic systems that automate specific osteotomies during a resection procedure, further increasing the precision. Given the significant potential for benefit in orthopaedic oncology, it is expected that development and optimization of these systems for application in musculoskeletal tumor resection will continue over the coming years.
A Comparison of Prospective Memory and Executive Processes in Patients with Subcortical Illness

Dementia is a common disorder affecting neuropsychological function in several spheres of mental activity including language memory, visuospatial function, and cognition. Studies into the cognitive deficits associated with dementia have allowed researchers to rank disorders into two subclasses: cortical and subcortical dementia. Cortical dementias such as Alzheimer's disease have been the focus of a plethora of studies. Subcortical dementia, which is commonly found in Parkinson's disease and Huntington's disease patients, is marked by bradyphrenia, visuospatial abnormalities, personality alterations, memory disturbances primarily involving recall but not recognition, and loss of executive functions. The most recent disorder to be classified as a cause of subcortical dementia is Human Immunodeficiency Virus (HIV) infection. Several studies have focused on memory disturbances associated with HIV infection but few have looked at the affects of the disease on executive function. The current study examined executive functioning, immediate recall, and prospective memory in patients with HIV, HD, older adult controls, and younger adult controls. The young adults performed significantly higher than the older adults and the HIV group on the Color-Word score of the Stroop test. The HIV group did not perform significantly differently from either of the control groups on any of the other measures. A Huntington's patient was analyzed using a case study method. The results suggest that HIV patients do not display significant signs of frontal mediated or executive function loss but several promising trends in the data are discussed. Further research is needed using larger group sizes and improving on several other limitations of the tests used in this study.
