Nafion‐multi‐walled Carbon Nanotubes Supported Tris(bipyridyl)iron(II) for Nicotine Detection

Field: Chemistry (Physical Sciences)

Abstract This work reports an electrochemical sensing framework for nicotine determination based on glassy carbon electrode (GC) immobilized with Fe(bpy) 3 2+ (where bpy is 2,2’‐bipyridyl) supported by Nafion and multi‐walled carbon nanotubes (Nf‐MWCNTs). Fe(bpy) 3 2+ immobilized Nf‐MWCNTs modified GC (GC/Nf‐MWCNTs/Fe(bpy) 3 2+ ) manifests stable redox peaks, characteristics of Fe(bpy) 3 2+ . The GC/Nf‐MWCNTs/Fe(bpy) 3 2+ exhibits effective electrochemical oxidation of nicotine, diminishing the overpotential relative to GC/Nf‐MWCNTs. The limit of detection is 0.1 μM (experimentally observed) with two different linear calibration ranges between 0.1 to 600 μM and 600 to 3000 μM. Electrocatalytic responses observed at GC/Nf‐MWCNTs/Fe(bpy) 3 2+ indicate superior performance for nicotine determination with acceptable selectivity, stability, and reproducibility. Additionally, the nicotine present in real samples such as beedi and tobacco are also analyzed with satisfactory recovery percentages.
[Local resources in management of adult victims of violence and abuse: a method of presentation and diffusion].

Field: Health Professions (Health Sciences)

Always more health problems require integrated care. So professionals needs to be aware of local and regional network resources (social, legal, home care, etc.) and specific offers of each individual institution. This article present a method used for creating a register of institutions involved in adults violence and elder abuse, for health professionals. Dates collected by interviewing professionals permitted to class institutions by intervention domain and offer. Five utility indicators (POUCE method) were selected for the register. A score has been attributed to each institution according to their problematic-related offers. Professional in charge of each institution validated information. This map, available in paper or CDrom, affords general practitioneer a quick and targeted access to a large number of dates, according to patient needs. This method could be useful for other health problems requiring exhaustive and targeted information about local and regional community resources (alcoholism, addiction, palliatives care, etc.)
The Concept of Information in Biology

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The use of informational terms is widespread in molecular and developmental biology. The usage dates back to Weismann. In both protein synthesis and in later development, genes are symbols, in that there is no necessary connection between their form (sequence) and their effects. The sequence of a gene has been determined, by past natural selection, because of the effects it produces. In biology, the use of informational terms implies intentionality, in that both the form of the signal, and the response to it, have evolved by selection. Where an engineer sees design, a biologist sees natural selection.

Patient mobility and medical tourism for the liberation therapy procedure by multiple sclerosis patients: a framing analysis of Canadian newspapers

Field: Social Sciences (Social Sciences)

Mobility in all of its forms is highly commodified in a globalised system. Much focus on mobility theory has offered a new ‘mobilities turn’. Largely absent from this ‘mobility turn’ is an examination of the relationship between mobility and health. This case study focuses on the Canadian televised and print media attention given to a medically contested procedure: liberation therapy (LT), which emerged as the possible treatment for multiple sclerosis (MS). As a non-insured service, Canadian MS patients wanting access to the procedure must travel to other geographical locations in what is termed as medical tourism. A comprehensive media analysis reveals an overwhelming patient mobility in the hopes of positive outcomes mainly from anecdotal stories. Patients’ advocacy for LT intensified and this pressured governments’ to fund clinical trials. This highlights the influence of the media in mobilizing patients and directing resources for research in the Canadian health care system.

Comparative Psychophysiological Studies of Alcoholic and Nonalcoholic Subjects Undergoing Experimentally Induced Ethanol Intoxication

Field: Neuroscience (Life Sciences)

Four nonalcoholic and 4 alcoholic subjects were studied under metabolic ward conditions before, while, and after they underwent experimentally induced ethanol intoxication. Behavioral and psychophysiological findings obtained from each group are compared and contrasted. Nonalcoholic subjects showed aversive behavioral responses to drinking and developed gastrointestinal signs and symptoms during the drinking phase of the experiment. The alcoholic subjects showed no aversive behavioral or psychophysiological responses while drinking. Significant changes in rate of C14 ethanol metabolism following drinking were found in both groups, but the nonalcoholics tended to have lower rates of C14 ethanol metabolism prior to drinking. Findings of this experiment suggest that neural, gastrointestinal, and metabolic adaptational processes occur in alcoholics which differentiate them from nonalcoholic subjects.
The Ideal Membership Problem and Abelian Groups

Field: Mathematics (Physical Sciences)

Given polynomials f_0, f_1, …, f_k the Ideal Membership Problem, IMP for short, asks if f₀ belongs to the ideal generated by f_1, …, f_k. In the search version of this problem the task is to find a proof of this fact. The IMP is a well-known fundamental problem with numerous applications, for instance, it underlies many proof systems based on polynomials such as Nullstellensatz, Polynomial Calculus, and Sum-of-Squares. Although the IMP is in general intractable, in many important cases it can be efficiently solved. Mastrolilli [SODA'19] initiated a systematic study of IMPs for ideals arising from Constraint Satisfaction Problems (CSPs), parameterized by constraint languages, denoted IMP(Γ). The ultimate goal of this line of research is to classify all such IMPs accordingly to their complexity. Mastrolilli achieved this goal for IMPs arising from CSP(Γ) where Γ is a Boolean constraint language, while Bulatov and Rafiey [arXiv'21] advanced these results to several cases of CSPs over finite domains. In this paper we consider IMPs arising from CSPs over "affine" constraint languages, in which constraints are subgroups (or their cosets) of direct products of Abelian groups. This kind of CSPs include systems of linear equations and are considered one of the most important types of tractable CSPs. Some special cases of the problem have been considered before by Bharathi and Mastrolilli [MFCS'21] for linear equation modulo 2, and by Bulatov and Rafiey [arXiv'21] to systems of linear equations over GF(p), p prime. Here we prove that if Γ is an affine constraint language then IMP(Γ) is solvable in polynomial time assuming the input polynomial has bounded degree.
Applicability constraints of the equivalence theorem

Field: Physics and Astronomy (Physical Sciences)

In this work we study the applicability of the Equivalence Theorem, either\nfor unitary models or within an effective lagrangian approach. There are two\ntypes of limitations: the existence of a validity energy window and the use of\nthe lowest order in the electroweak constants. For the first kind, we consider\nsome methods, based on dispersion theory or the large $N$ limit, that allow us\nto extend the applicability. For the second, we have obtained numerical\nestimates of the effect of neglecting higher orders in the perturbative\nexpansion.\n
Presence of two mitochondrial genomes in the mytilid Perumytilus purpuratus: Phylogenetic evidence for doubly uniparental inheritance

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

This study presents evidence, using sequences of ribosomal 16S and COI mtDNA, for the presence of two mitochondrial genomes in Perumytilus purpuratus. This may be considered evidence of doubly uniparental mtDNA inheritance. The presence of the two types of mitochondrial genomes differentiates females from males. The F genome was found in the somatic and gonadal tissues of females and in the somatic tissues of males; the M genome was found in the gonads and mantle of males only. For the mitochondrial 16S region, ten haplotypes were found for the F genome (nucleotide diversity 0.004), and 7 haplotypes for the M genome (nucleotide diversity 0.001), with a distance Dxy of 0.125 and divergence Kxy of 60.33%. For the COI gene 17 haplotypes were found for the F genome (nucleotide diversity 0.009), and 10 haplotypes for the M genome (nucleotide diversity 0.010), with a genetic distance Dxy of 0.184 and divergence Kxy of 99.97%. Our results report the presence of two well-differentiated, sex-specific types of mitochondrial genome (one present in the male gonad, the other in the female gonad), implying the presence of DUI in P. purpuratus. These results indicate that care must be taken in phylogenetic comparisons using mtDNA sequences of P. purpuratus without considering the sex of the individuals.
Welcoming Our Robot Overlords: Initial Expectations About Interaction With a Robot

Field: Psychology (Social Sciences)

Because robots and other electronic agents perform increasingly social functions, people will soon face the possibility of more frequent human–robot interactions. But what kinds of expectations do people bring with them into these potential interactions? Based on the possibility of a human-to-human interaction script, the current research hypothesized that people will be more uncertain about, anticipate less social attraction to, and expect less social presence when they expect to interact with a robot as opposed to another human. An experiment was designed in which people were told they would interact with either a robot or another person, and each of these three expectations was measured. The data were consistent with each of three hypotheses. These findings are discussed, as are avenues for future research.
Effects of effort-reward imbalance, job satisfaction, and work engagement on self-rated health among healthcare workers

Field: Health Professions (Health Sciences)

Abstract

Background: Healthcare workers, whose job is to protect and improve the health of populations, are critical to the success of health systems and to achieving national and global health goals. To respond effectively to the health needs of populations, healthcare workers themselves must be in a perfect state of health. However, healthcare workers face various psychosocial pressures, including night shifts, long working hours, demands of patient care, medical disputes, workplace violence, and emotional distress due to poor interactions with patients and colleagues and poor promotion prospects. Constant exposure to these psychosocial hazards adversely impacts healthcare workers’ health. This study aimed to examine the influence of effort-reward imbalance, job satisfaction, and work engagement on self-rated health among healthcare workers, which is conducive to providing policy guidance from several aspects as possible as to improve healthcare workers’ health. Methods : The Chinese Sixth National Health and Services Survey in Sichuan Province was conducted from August 2018 to October 2018, and we analysed 1327 valid responses. We used structural equation modelling (SEM) to test the hypothesized relationship among the variables. Results: Only 40.1% of healthcare workers rated their health as ‘relatively good’ or ‘good’. Effort-reward imbalance had a significant negative correlation with self-rated health (β=-0.053, 95%CI: (-0.163) -(-0.001)). The relationships of effort-reward imbalance and work engagement with self-rated health were both mediated by job satisfaction (95%CI: (-0.150) -(-0.050), (0.011) -(0.022)). Work engagement mediated the relationship between effort-reward imbalance and self-rated health (95%CI: (-0.064) -(-0.008)). Conclusion: In order to improve the health of healthcare workers, administrators should balance effort and reward and provide opportunities for career development and training for healthcare workers. In addition, health managers should help healthcare workers realize the significance and value of work and help keep them actively devoted to their work through incentive mechanisms.

The Demand for Money and the Term Structure of Interest Rates in Ireland, 1971-1981

Field: Economics, Econometrics and Finance (Social Sciences)

This paper investigates the extent to which the demand for various measures of money in Ireland depends upon the term structure of interest rates. The yield to maturity curve is first estimated using refinements of the approximation specification employed by Heller and Khan (1979). The estimated parameters are then entered as parameters into the money demand equations which are estimated using autoregressive least squares. Amongst other findings is a considerably greater response of money demand to a uniform shift in the yield curve than is obtained using conventional estimates which are based on only a single interest rate.
Atomistic Molecular Dynamics Simulations of the Initial Crystallization Stage in an SWCNT-Polyetherimide Nanocomposite

Field: Materials Science (Physical Sciences)

Crystallization of all-aromatic heterocyclic polymers typically results in an improvement of their thermo-mechanical properties. Nucleation agents may be used to promote crystallization, and it is well known that the incorporation of nanoparticles, and in particular carbon-based nanofillers, may induce or accelerate crystallization through nucleation. The present study addresses the structural properties of polyetherimide-based nanocomposites and the initial stages of polyetherimide crystallization as a result of single-walled carbon nanotube (SWCNT) incorporation. We selected two amorphous thermoplastic polyetherimides ODPA-P3 and aBPDA-P3 based on 3,3′,4,4′-oxydiphthalic dianhydride (ODPA), 2,3′,3,4′-biphenyltetracarboxylic dianhydride (aBPDA) and diamine 1,4-bis[4-(4-aminophenoxy)phenoxy]benzene (P3) and simulated the onset of crystallization in the presence of SWCNTs using atomistic molecular dynamics. For ODPA-P3, we found that the planar phthalimide and phenylene moieties show pronounced ordering near the CNT (carbon nanotube) surface, which can be regarded as the initial stage of crystallization. We will discuss two possible mechanisms for ODPA-P3 crystallization in the presence of SWCNTs: the spatial confinement caused by the CNTs and π–π interactions at the CNT-polymer matrix interface. Based on our simulation results, we propose that ODPA-P3 crystallization is most likely initiated by favorable π–π interactions between the carbon nanofiller surface and the planar ODPA-P3 phthalimide and phenylene moieties.

Axial Wave Propagation in Infinitely Long Periodic Curved Panels

Field: Engineering (Physical Sciences)

Propagation of waves along the axis of the cylindrically curved panels of infinite length, supported at regular intervals is considered in this paper to determine their natural frequencies in bending vibration. Two approximate methods of analysis are presented. In the first, bending deflections in the form of beam functions and sinusoidal modes are used to obtain the propagation constant curves. In the second method high precision triangular finite elements is used combined with a wave approach to determine the natural frequencies. It is shown that by this approach the order of the resulting matrices in the FEM is considerably reduced leading to a significant decrease in computational effect. Curves of propagation constant versus natural frequencies have been obtained for axial wave propagation of a multi supported curved panel of infinite length. From these curves, frequencies of a finite multi supported curved panel of k segments may be obtained by simply reading off the frequencies corresponding to jπ/kj=1,2…k. Bounding frequencies and bounding modes of the multi supported curved panels have been identified. It reveals that the bounding modes are similar to periodic flat panel case. Wherever possible the numerical results have been compared with those obtained independently from finite element analysis and/or results available in the literature.

Development of Materials Characterization Procedure for Composite Aircraft

Field: Materials Science (Physical Sciences)

It is required to characterize the materials according to the regulation in order to manufacture and fabricate components to be used for aircraft. The main purpose of this requirement is to determine the suitability of materials used for safe flight. Since the properties of composite materials are sensitive to the processing, characterization of composite materials has required very conservative methodology and therefore the whole process of characterization has been a redundant and time consuming process. This paper summarizes the efforts to adopt the composite materials characterization procedure for composite aircraft and provide the effective statistical methodology for evaluating composite materials manufacturing process. The result will be applied to the materials certification procedure for domestic composite materials for aircraft within the level of a global standard.
Differences in coping strategies in adult patients with bipolar disorder and their first-degree relatives in comparison to healthy controls

Field: Psychology (Social Sciences)

Abstract Introduction: The objective of this study was to compare patients with bipolar disorder (BD), their first-degree relatives and a group of healthy controls in terms of use of adaptive and maladaptive coping strategies, exploring differences between specific types of strategies and their correlations with clinical variables. Methods: This was a cross-sectional study enrolling 36 euthymic patients with BD, 39 of their first-degree relatives and 44 controls. Coping strategies were assessed using the Brief COPE scale. Results: Significant differences were detected in the use of adaptive and maladaptive strategies by patients, their first-degree relatives and controls. Patients used adaptive strategies less often than the patients’ relatives (p<0.001) and controls (p = 0.003). There was no significant difference between first-degree relatives and controls (p=0.707). In contrast, patients (p<0.001) and their relatives (p=0.004) both exhibited higher scores for maladaptive coping than controls. There was no significant difference regarding the use of maladaptive strategies between patients and their relatives (p=0.517). Conclusions: First-degree relatives were at an intermediate level between patients with BD and controls regarding the use of coping skills. This finding supports the development of psychosocial interventions to encourage use of adaptive strategies rather than maladaptive strategies in this population.
