Effects of gamma irradiation on the physical properties of PAni.MWCNT/PMMA films

In this study, the eﬀect of gamma irradiation on PAni.MWCNT/PMMA ﬁlms was investigated, for using them as dosimeters. In particular, the eﬀects of gamma irradiation on the morphological characteristics, structure, electrical conductivity, and some optical properties of PAni.MWCNT/PMMA ﬁlms were studied before and after irradiation. Samples were fabricated by casting method, obtained by using PAni.MWCNT with 3.8 wt% PMMA weight ratio, and exposed to a (Cs 137 ) gamma-radiation source at diﬀerent dose rates (0, 2.7, and 4.8 kGy) at room temperature. The morphological characteristics of the PAni.MWCNT/PMMA ﬁlms were examined through scanning electron microscopy. X-ray diﬀraction analysis revealed the eﬀect of irradiation on the structure and average crystallite size of the ﬁlms. The FTIR was carried out for samples within the range 600–4000 cm − 1 to study the functional groups of PAni.MWCNT/PMMA ﬁlms, and the presence of characteristic bonds of PAni.MWCNT/PMMA ﬁlms were observed using FTIR spectroscopy technique. Electrical conductivity analysis showed that the conductivity of the unirradiated ﬁlm of 2.02 × 10 − 8 S.cm − 1 increased to 2.77 × 10 − 8 S.cm − 1 after the samples were exposed to 4.8 kGy. The absorption spectra of the PAni.MWCNT/PMMA ﬁlms were also obtained. Spec-tral analysis demonstrated that optical transition was an allowed direct transition, and the optical band gap increased as the radiation dose increased. The observed changes in these physical properties suggested that PAni.MWCNT/PMMA ﬁlms may be used as an eﬀective material for gamma radiation dosimeters at room temperature.
Influence of cutting conditions on surface characteristics in micro-milling of Ti-6Al-7Nb alloy

ABSTRACT Ti-6Al-7Nb alloy is widely used in the manufacturing of medical implant. In this work, experimental study on micro-milling of Ti-6Al-7Nb is exemplified to analyze cutting conditions effect on surface texture. Process variables including cutting speed (vc), feed rate (fn) and depth of cut (ap) are considered. Responses in the form of surface topography variables including Average Surface Roughness (Ra), Maximum Average Profile Height (Rz) and Maximum Profile Peak Height (Rp) are measured. Dental implants are generally micro and miniature in nature to ensure functionality of a human bone. Hence, 20 micro-slot of 500 μm size are produced using Carbide end mill cutter under dry condition. Surface plots are drawn and are observed that ‘ap’ possess foremost effect on surface quality. Minimum ‘ap’ yields good surface finish of 0.1 µm. Analysis of variance also proves ‘ap’ effects on surface quality. Surface morphology study reveals grooves formation and particle deposition on finished surface at excessive ‘ap’ condition. Burr formation analysis shows the development of knife edge and wave-type burr for lower and higher ‘ap’ conditions, respectively. Hence, it is inferred that at lower ‘ap’ values (60 µm), desired surface finish of 0.1 µm is achieved in Ti-6Al-7Nb alloy that promotes better osseo-integration.
Evaluation of the nutritional status using the anthropometric indices and dietary intakes in the central prison of Mashhad

ABSTRACT High possibility of diet lacking in essential nutrients between the prisoners that could lead to malnutrition; to evaluate the nutritional status of the prisoners and check the rate of nutritional disorders between them. A cross-sectional, randomized study carried out on a sample of 435 prisoners. Questionnaires including gender, age, types of food intake and type of crime were completed. Anthropometric indices were measured on the base of WHO standards. Two weeks food menu of the prison was checked. The outcomes were analyzed using SPSS. The mean BMI value for male and female prisoners was 24.5 and 28.3 kg / respectively. The prevalence of underweight, overweight and obesity were 13.8%, 5.5% and 1% m2 respectively. The prevalence of underweight was significantly more in men (p<0.05) compared with women. In contrast, the prevalence of overweight and obesity was much more in women compared with men. Inadequate supply of calories for men and protein for all the prisoners was recognized in the prison food menu. Results from this study showed that malnutrition risk was high in Mashhad central prison especially for male prisoners.
Expression Analysis of Gata4, Tbx5 and Nkx2.5 Genes Involved in Congenital Heart Disease

Background: Congenital heart disease (CHD) is the most widespread congenital disease in newborn babies and is one of the main causes of death worldwide. The causal agent of heart congenital diseases is unknown but genetic factors have an important role in prevalence of disease. Objectives: The main objective of this research is comparison of the gene expression level of three Gata4, Tbx5 and Nkx2.5 genes in three groups of children between 6 months and 13 year old with congenital heart disease. Patients and Methods: In this case-control study, 30 samples from each cyanotic and acyanotic patients and 30 samples from healthy children as control were used. RNA extraction was done using commercial kit and gene expression analysis was performed by qRT-PCR approach in three replication using Gata4, Tbx5 and Nkx2.5 genes. Data analysis was done by REST software. Results: The results of RNA extraction and cDNA synthesis of all sample showed high quantity and quality of genetic materials. Expression level of tested genes was reduced in two patients group. In cyanotic group reduction was more than acyanotic samples. All tested gene were reduced in both group. Tbx5 gene was suppressed more than other genes. Conclusions: Based on our results we could conclude that a gene family play an important role in cardiogenesis process and heart formation. These genes are closely related together. So a genetic consultation for such diseases on parents of these patients to determine the probable genetic mutations is recommended.
Changes in health status and frequency of attending religious services among medical inpatients with repeat admissions

ABSTRACT Although frequent attendance at religious services is associated with healthier behaviors and improved health outcomes, this relationship is confounded to the extent that attending religious services requires and displays a certain degree of health. This study surveyed patients over multiple hospitalizations at a large urban academic medical center to test the hypothesis that changes in health status would be accompanied by parallel changes in religious attendance but not with self-rated religiosity and spirituality. Study data confirmed the hypothesis, suggesting that cross-sectional associations between religious attendance and good health outcomes reflect, to some degree, the way changes in health status impact one’s ability to attend religious services.
A Study of the Relationship between Proenvironmental Product Use and Environmnetal Concern

To be sustainable, an organization must be balanced in the three principles of economy, environment, and society. Advances in pro-environmental technology have overcome roadblocks limiting the economic and environmental principles. The remaining hurdle to becoming sustainable is having society’s beliefs and behaviors align. Understanding the interaction between an individual’s environmental belief and environmental behaviors is essential to bringing them into alignment. To explore this relationship, a model was developed that included the new ecological paradigm (NEP) scale and a generalized version of the theory of planned behavior (TPB). The attitudes, intentions, and use of six pro-environmental products were measured in an electronic survey. It was found that the model was adequate in measuring the general attitudes, intentions, and behaviors of individuals. In addition, environmental concern was shown to correlate with the attitudes of an individual. It was also found that the survey questionnaire should be modified to strengthen the relationships found.

In this 28 knee had osteoarthritis knee and 6 knee had rheumatoid arthritis. Infective, traumatic and metabolic bone disease knees were excluded from study. All patients were evaluated by American knee society score (KSS and functional score). RESULT : Total knee arthoplasty was found to be associated with substantial functional improvement. The greatest amount of improvement is seen within few months after surgery with more gradual improvement occurring up to years of surgery. CONCLUSION: Total knee arthoplasty is a very effective procedure for overall functional improvement and pain relief of the patient with arthritic knee.
Risk Factor Analysis of Postoperative Complications in Crohns Disease Patients

Objective To investigate the risk factors of complication rate after bowel resection for (Croh`s disease CD). Methods Forty-five patients underwent bowel resection for CD were retrospectively analyzed by using logistic regression models. All cases were classified into two groups basing on the presence of complica tions. The related factors including gender, age, course of disease, HB, Alb, surgery or not and operative pattern were analyzed. Results Postoperative complications occurred in 12 cases , which included intestinal obstruction in 9 cases , anastomotic leakage in 5cases , incisional infection in 5 cases. Preoperative nutrition, preoperative glucocorticoid use, and the anastomosis of end-to-side or end-to-end were considered as the risk factors of post operative complications in crohn`s disease patients. Conclusion Recognizing these risk factors helps to decrease complications after operation.

Risk of cancer other than breast or ovarian in Chinese Han women with BRCA1/2 mutations

Objective To investigate the risk of cancer other than breast or ovarian in Chinese Han women with family breast cancer who carried a BRCA1 or BRCA2 mutation.Methods Germline mutations in BRCA1/2 genes in the cohort of 465 Chinese Han patients with familial breast cancer were screened using a PCR-sequencing assay.The proportion of cancer other than breast or ovarian was compared in mutantion group and non mutation group.Results Among the 465 familial breast cancer patients,47 (10.1％) were BRCA1/2 mutation carriers and 418 (89.9％) were non-carriers.There was no significant difference in the total proportion of cancers other than breast or ovarian in the family between BRCA1/2 mutation carriers and non-carriers (27.7％ ∶29.9％,x2 =0.10,P=0.75). But the tumor spectrum was different between the BRCA1/2 carriers and non-carriers.In the family of BRCA1/2 carriers,the most common cancers were gastric cancer,pancreatic cancer,and prostate cancer; while in the non-carriers,the most common cancers were lung cancer,gastric cancer,and esophageal cancer.The relative risk of gastric cancer,pancreatic cancer and prostate cancer was significantly higher in the families of BRCA1/2 mutation carriers than that of non-carriers (17％∶7.7％,odd ratio:2.47,95％ CI:1.07-5.74,P =O.048). Conclusion This study suggests that the relative risk of gastric cancer,pancreatic cancer and prostate cancer in BRCA1/2 carriers is moderate higher than in non-carriers in Chinese Han women.

Disadvantaged School Contexts and Female School Leadership in Zimbabwe

Abstract The persistent systemic inequalities inherent in cultural and traditional practices shape how society views women as leaders. This article reviewed the literature to highlight the needs, opportunities, constraints, and resources of disadvantaged schools and how this context influences the leadership practices of female primary school principals. Two questions guided the study: (1) What are the needs, opportunities, constraints, and resources of disadvantaged schools and how do they influence leadership practice? (2) How do female principals adapt their practices to their school contexts? An unbounded search was conducted to identify 22 publications, consisting of 17 peer-reviewed English-language journal articles, three book chapters, and two conference papers on female educational leadership in Zimbabwe. Systematic search criteria were strictly followed to obtain the publications from 2008 to 2018. Through the lens of an African feminist perspective, this study established that the features of a disadvantaged school context influence what female principals do and how they do it. It is important to note that principals craft strategies to expand the available resources while taking advantage of the opportunities at their disposal to manage constraints in order to meet the needs of their schools.
Psychophysiological Differences in Individual and Cooperative Video-Game Play: An Exploratory Study

To advance knowledge on the notions of “coordination cost” and “team learning”, this study sought to explore differences in psychophysiological functioning among individuals playing a video-game (1) in a solo condition or as part of a dyadic team; (2) over three consecutive games in a dyadic team. Data from twenty-four dyads were collected for Study 1 and Study 2. The participants were all male with no less than 30 hours of experience in the video-game and 21 years of age on average. In Study 1 the participants played FIFA-17 (Xbox) against the computer in a solo and in a dyad condition. In Study 2 the participants played three consecutive games in a dyad against the computer. Performance measures, subjective psychological self-reports, and objective psychophysiological data were collected for both studies. In Study 1 Heart Rate Variability (p <.01, d = -.57) decreased, whereas power on the central (C4; p = .04, d = .78), parietal and temporal areas of the brain increased in the dyadic condition (Pz; p = .03, d = .44, T6; p = .04, d = .63). Therefore, playing in a team, in contrast to playing alone, was associated with higher cognitive neural load. In Study 2, Number of Fouls (p <.01, d = 2.41) and HRV (p <.01, d = .55) increased over time, whilst a decrease in power was observed in the frontal area of the brain (Fp1 p = .05, d = -.36, Fp2; p = .05, d = -.40). These findings suggest that conflicts occur in the initial stages of team development, and that learning of team (and motor) tasks leads to hypofrontality. Collectively, these findings advance the literature by demonstrating that (1) cognitive-neural and affective processes change in individual and team settings in line with the notion of “coordination cost”; and (2) team dynamics and individuals’ brain patterns change over time due to “team learning” and intra-team conflict.
Police department perceptions of the mobility and safety of online vs offline prostitutes

Purpose To date, there is a gap in the literature exploring the perceptions and experiences of law enforcement regarding enforcement of online and offline prostitution. The purpose of this paper is to investigate the perceptions of law enforcement in the USA regarding the safety and mobility of individuals who prostitute online compared to those who sell sexual services offline. The next section will explain the methodology of the exploratory study, including the method of original data collection. Design/methodology/approach All police departments in the USA located in a jurisdiction of 50,000 people or more were requested participation in the study (n=689). Respondents were sent an initial mailing of a cover letter and survey, followed by an e-mail reminder and a second mailing of a cover letter and survey. Individual respondents were asked questions about their own perceptions of behaviors and lifestyles of offline vs online prostitutes. Findings The majority of law enforcement respondents did not feel as if online prostitutes were safer compared to offline prostitutes. However, the majority of respondents did believe that online prostitutes are afforded a better lifestyle and are more mobile. Research limitations/implications The majority of the respondents were from the Northeast and Southwest may mean that their perceptions could be different from those that are not located within either region. In addition, since almost 80 percent of the agencies were in a jurisdiction with a population between 50,000 and 249,000, this too may have influenced their perceptions. Law enforcement in a smaller or larger area may have felt differently or have had different experiences to report. Originality/value This study is very unique as to date, another study with the same methodology and question content was not found.
Drivers and barriers in public diplomacy evaluation: understanding attitudes, norms, and control

While the need for evaluation has become increasingly emphasized within the global public diplomacy community, recent research suggests the state of the practice is grim. However, the few writings that exist on evaluation practices in public diplomacy are anecdotal and focus mainly on obstacles to enacting evaluation behavior. Little is known about evaluation-related perceptions, motivations, and attitudes of public diplomacy practitioners themselves. As practitioners are under increasing pressure to deliver evaluations, understanding the perspective of practitioners and their motivations is necessary. Drawing on the theory of planned behavior, this study presents the results of interviews with 25 public diplomacy practitioners in the U.S. Department of State. The results lend insight into the attitudes, norms, and behavioral controls that influence practitioners’ intentions to engage in evaluation. The article also suggests explanations as to why evaluation struggles to gain a foothold within public diplomacy, and makes proposals for improving future practice.
Effectiveness of Self-directed Learning on Competency in Physical Assessment, Academic Self-confidence and Learning Satisfaction of Nursing Students

Purpose: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. Methods: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using x 2 -test (Fisher"s exact test) and independent t-test. Results: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. Conclusion: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students" competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.
Question Asking and the Common Good: A Hermeneutic Investigation of Student Questioning in Moral Configurations of Classroom Practice

This qualitative study (based on a hermeneutic moral-realist interpretive frame (Yanchar & Slife, 2017)) explored question asking as it unfolded in the everyday practice of being a student in a graduate course on design thinking (with an emphasis on design in education). Findings are presented as four key tensions that occurred within the complex classroom setting under investigation: “theory and overlapping practices,” “convergence and divergence,” “participation and reticence,” and “give and take. ” Overall, these thematized tensions point to a dynamic interplay between student agency and the common good of the class. These findings have significant implications for understanding student questioning experiences and the study of classroom interactions.
