Flame-Sealed Tube Graphitization Using Zinc as the Sole Reduction Agent: Precision Improvement of EnvironMICADAS 14C Measurements on Graphite Targets

The flame-sealed tube zinc reduction graphitization method has been successfully adapted and optimized for radiocarbon measurements on EnvironMICADAS in the Institute for Nuclear Research of the Hungarian Academy of Sciences, Hertelendi Laboratory of Environmental Studies (ATOMKI HLES). To reduce the cost and treatment time of producing graphite targets from samples of about 1 mg carbon content, we have omitted the titanium hydride (TiH2) reagent and used a decreased amount of zinc as the sole reductant in our new method. These changes have also helped to eliminate methane formation during the graphitization processes as well as to recover higher ion current at the same background level. These conditions have led to improved efficiency in the 14C measurements; furthermore, the instrument background level remained sufficiently low (<49,000 yr BP). After determining the optimum parameters of the new Zn graphitization method (2.5 mg Fe powder, 15.0 mg Zn powder, 10 hr graphitization at 550°C in heating block, reaction cells with reagent pretreated at 300°C for 1 hr), verification of the accuracy was carried out by the preparation and measurement of IAEA standard samples (C2, C6, C7, C8) with known 14C activity. The sensitivity of the method for gas contamination was tested and determined by comparing the results to measurements of reserved portions of previously processed real samples.
The Use of Food Coloring Dyes in Bacterial Staining

Staining creates a contrast between the cells and its surrounding, and enables the microscopic characteristics of bacterial cells to be easily visible and distinguished. However, staining often relies on dyes which are expensive, not readily available, or toxic. In this study, the use of food coloring dyes to stain bacteria was explored. We stained Gram- positive bacteria ( Bacillus sp . and Staphylococcus aureus ) and Gram-negative bacteria ( Escherichia coli ) using several food coloring dyes of different colors, which were purchased locally. After slide fixation, the dye was flooded on the bacterial smear and air-dried for up to 30 minutes and observed by using microscope before and after washing with water. The results of this study show that prior to washing, most food coloring dyes were able to stain bacterial cells. However, after washing, only pink and purple food coloring dyes were retained, showing pink colored cells. We suspected that erythrosine was the agent responsible for this result, and was able to show similar characteristics with erythrosine alone. This study concludes that food coloring dyes containing erythrosine can be used to stain bacterial cells indiscriminately. Keywords: Bacterial cell staining, erythrosine, food coloring dyes, resource-limited.
Effect of Antagonist Mineralocorticoid Receptors Eplerenon on the Dynamics of QT Interval Dispersion in Patients with Acute Elderly Aged

The steady aging of the population of developed countries increases the proportion of cardiovascular diseases in the overall structure of the incidence, which leads to an increase in the number of elderly patients in the practice of doctors of many specialties. Currently, there is an increase in the frequency of cardiovascular diseases, including acute coronary syndrome (ACS), while in the Russian Federation due to ACS there is a high mortality rate from sudden cardiac death (SCD). The aim of the work is a comparative analysis of the effect of mineralocorticoid receptor antagonists (MRA) of eplerenone on the predictors of SCD development in patients with ST elevation myocardial infarction (STEMI) with a moderately abnormal ejection fraction(EF) of the left ventricle (LV) in the early stages of the disease. Materials and methods. A total of 52 patients with STEMI who underwent myocardial reperfusion were examined. Patients are divided into 2 groups by age. 26 patients of middle age and 26 patients of elderly. The average age of the patients of the 1st group was 57.6 ± 10.5 years, 2 groups: 69.04 ± 2.02, the mean indicators of LVEF 35.34 ± 4.7%. All patients were examined in the first and thirtieth days of rehabilitation treatment. The dynamics of indicators of BCC predictors (dispersion of the QT interval and its parts with correction using the Bazett formula) were assessed: QTd, QTcd, QTapd, JTd, JTapd, SubTd, SubTcd (ms). Results. In a comparative analysis of the effect of MRA on day 30, eplerenone in middle-aged patients had a significantly greater effect on the corrected QT interval: reducing the QTd interval by 16.7%; Δ18. 06 ms (p = 0.38), QTcd by 23.7%; Δ27. 94 ms (p = 0.024), QTapd by 20.1%; Δ3. 1 ms (p = 0.031), JTapd by 14.5%; Δ17. 4 ms (p = 0.043), SubTcd by 12.8% Δ14.7 ms (p = 0.043) in relation to treatment in elderly patients.
Macroeconomic Variables and Stock Market Interactions: Indonesia Evidence

The existence of semi strong-form pricing efficiency on the LQ 45 Index in the Indonesia Stock Exchanges from 2004 to 2014 for using monthly closing prices was investigated. This study provides evidence on the Indonesia Stock Exchanges (IDX) using semi strong-form efficiency test. This paper employs the integration test, which is widely used to distinguish the impact of macroeconomic factors (The consumer price index, exchange rate, gross domestic product, and interest rate) to market returns (Lq45 Index). The findings indicate that in Indonesia Stock Exchanges show mixed evidence of Semi strong form pricing efficiency characteristics for monthly return series. The results implied that the new information have impacted on the Indonesia Stock Exchanges by making exchanges becoming more price efficient.
The Rubber Hand Illusion and Skin-to-Skin Touch: Does the Touch of Others Matter for Feeling Like Me?

In this study we investigated if skin-to-skin touch moderates the effect of the Rubber Hand Illusion. Twenty participants (all right-handed) took part in the experiment. The participants’ own hands (hidden from view) were either stroked in synchrony (should induce the illusion) or asynchrony (control condition) with a rubber hand, using the experimenter’s own hand, a wide brush or a small brush. We found no significant difference for the stimulation types for the proprioceptive drift F(2, 19) = . 33, p = . 72 or for the subjective rating, F(2, 19) = . 43, p = . 65. However, both outcome measures showed the same trend (that the skin-to-skin touch induced the strongest illusion) and therefore we neither conclusively rejected nor confirmed our hypothesis. The sense of self, the feeling of being “me”, stems greatly from the fact that we feel that our body is our own. In the words of French phenomenologist philosopher Maurice Merleau-Ponty (1962, p. 169): “The body is our general medium for having a world”. The fact that the sense of agency seems to be so greatly intertwined with the subjective feeling of being a self, was for long thought of as a great obstacle to the study of the phenomenon of embodiment. This sense of agency is something that is hard to separate from the other aspects of embodiment in day-to-day life, as we almost always have a feeling of control over our own body (Jeannerod, 2003). When we interact with the world we have the experience of being a discrete entity that is independent from other objects. We do not typically mistake something as alien as a lamp or a flowerpot for being part of our own body. Although under the right circumstances it is possible to transform this percept, so as to include different kinds of objects and also to feel limbs that have been lost to amputation (phantom limbs). The pioneering works by scientists such as Ramachandran (1998) on phantom pains have offered us insight into how this process works and shown that our body image is significantly more malleable than previously thought. Experiences such as voluntary self touch (Hara et al., 2015), the velocity of touch (Crucianelli, Metcalf, Fotopoulou & Jenkinson, 2013) and damage to the nervous system (such as in the syndrome somatoparaphrenia, where the patient do not feel ownership over certain body parts) (Vallar & Ronchi, 2008) have all been linked to changes in the system of body perception. Recent studies have also uncovered associated disturbances in different parts of this complex system (most crucially interoceptive awareness) in disorders of body perception, such as anorexia nervosa (Crucianelli, Cardi, Treasure, Jenkinson & Fotopoulou, 2016; Emanuelsen, Drew & Köteles, 2014; Eshkevari, Rieger, Longo, Haggard, & Treasure, 2011). In this study we seek to investigate the social factors that might contribute to our sense of embodiment (more specifically – tactile human interaction). This is something that, to our knowledge, has not yet been investigated in relation to the Rubber Hand Illusion (RHI).
STABILITY, FINITE-TIME STABILITY AND PASSIVITY CRITERIA FOR DISCRETE-TIME DELAYED NEURAL NETWORKS

In this paper, we present the problem of stability, finite-time stability and passivity for discrete-time neural networks (DNNs) with variable delays. For the purposes of stability analysis, an augmented Lyapunov-Krasovskii functional (LKF) with single and double summation terms and several augmented vectors is proposed by decomposing the time-delay interval into two non-equidistant subintervals. Then, by using the Wirtinger-based inequality, reciprocally and extended reciprocally convex combination lemmas, tight estimations for sum terms in the forward difference of LKF are given. In order to relax the existing results, several zero equalities are introduced and stability criteria are proposed in terms of linear matrix inequalities (LMIs). The main objective for the finite-time stability and passivity analysis is how to effectively evaluate the finite-time passivity conditions for DNNs. To achieve this, some weighted summation inequalities are proposed for application to a finite-sum term appearing in the forward difference of LKF, which helps to ensure that the considered delayed DNN is passive. The derived passivity criteria are presented in terms of linear matrix inequalities. Some numerical examples are presented to illustrate the proposed methodology.
Detection of Biofilm Formation and Antibiotics Resistance for Streptococcus Spp. Isolated from Some Dairy Products in Diwanyah City of Iraq

Multidrug resistance and biofilm formation have increasingly become a leading human threat in particular dairy products, which become the primary source of essential nutrients word-wide. Biofilm formation is responsible for economic losses in the dairy industry. Therefore, in current study, the multi-drugs resistance and biofilm formation were investigated for Streptococcus spp. isolated different dairy products (milk, cheese, and cream) collected from various markets in Diwanyah city, Iraq. Bacteria were isolated and identified by morphological and biochemical characteristics using selective agar plates. Antibiotic resistance was tested using disc diffusion method, whereas biofilm formation was investigated using Microtiter plate method (MTP). The results showed that Streptococcus spp. isolates in milk (7 isolates), cheese (17isolates), and cream (18 strains) showed high resistance against novobiocin, Nalidixic acid, streptomycin, and cephalothin. However, all isolates showed high sensitivity to vancomycin. Streptococcus isolates showed a variant level of biofilm formation with high percentages (71.43%) of strong biofilm formation in milk isolates, 29.4% in cheese, and 50% in cream. These results suggested that multidrug resistance Streptococcus spp. has been observed in some dairy products with a high ability for biofilm formation and could affect the quality of dairy products and probable human threats.
PEG–MWCNT/Fe hybrids as multi-modal contrast agents for MRI and optical imaging

This study examines the use of oxidized multi-walled carbon nanotube/iron (O-MWCNT/Fe) nanohybrids modified with polyethylene glycol (PEG) as multifunctional cellular imaging agents for magnetic resonance imaging (MRI) and fluorescence microscopy. The PEGylated MWCNTs with embedded iron particles were investigated as T2-weighted contrast agents for MRI. The number of PEG molecules attached to the MWCNT surface was calculated. The PEG–MWCNT/Fe complex was characterized by transmission electron microscopy, scanning electron microscopy, Fourier transform infrared and Raman spectroscopies. Covalent surface modification of the MWCNTs improves their solubility and enables the attachment of further biomolecules to their surface. The PEGylated nanostructures were labeled with the MDC organic dye and internalized inside HeLa cells for cellular imaging. Additionally, the minimal cytotoxic effect of PEGylated complexes in comparison to non-PEGylated samples was measured using the WST-1 test and an In Cell Analyzer. A confocal microscopy study of the organelle morphology also confirmed that the HeLa cell morphology was unchanged after treatment with PEGylated MWCNTs.
Are Tattooing Indicators of Dark Personalities? An Analysis of Body Modification within the Framework of Dark Triad of Personality

There are several displays commonly labeled as body modifications, including body piercings, scarification, tattoos, cutting, etc. In this study, we were focused on one distinct form of body modification, namely tattoos. The current exploratory study investigated the connection between body modifications (BM) and Dark Triad personality for a sample of 77 university students with BM, compared to a control group of 77 non-BM individuals. Three self-administrated questionnaires were used to collect the data: Self-Report Psychopathy Scale-Short Form, Mach-IV scale, and Narcissistic Personality Inventory. The findings suggest that subclinical psychopathy is most strongly connected to body modifications. An increased number of tattoos was also significantly correlated with a higher level of anti-sociality. Participants with visible body modifications had significantly higher affective callousness and overall self-reported subclinical psychopathy levels, compared with individuals with non-visible alterations.

Relationship Building in IoT Platform Models: the Case of the Danfoss Group

Purpose: This paper investigates the implications for a manufacturer’s relationship building towards B2B customers and suppliers as a consequence of Internet-of-Things (IoT) platform models. Design/methodology/approach: Explorative single case study with embedded sub-cases. Qualitative research approach. Semi-structured interviews. Findings: The paper identifies two ways of doing relationship building when it comes to IoT platform models. Relationship building can take place through a Classic Relationship IoT platform model (characterized by low complexity) or a New Relationship IoT platform model (characterized by high complexity). In both models, the manufacturer aims for high stickiness towards the customers. In the New Relationship model, however, low stickiness towards suppliers is aimed for in order to enable the manufacturer to orchestrate the stakeholder constellation dynamically. In addition, a driver for the low stickiness aim towards suppliers can be found in a motive to outsource risks to suppliers in IoT markets characterized by high degrees of turbulence and growth. Research limitations/implications: The study points to the fact that a manufacturer should consider how the new technology IoT gives opportunities for different ways of relating to stakeholders, e.g. customers and suppliers, in the business model. Originality/value: Based on primary data collection the research shows how strategic relationship building can help a manufacturer create value with customers and suppliers within IoT platform models. The paper expands the business model literature by investigating consequences of a new technology, i.e. IoT. Keywords: IoT, IoT platform model; platform stickiness; manufacturer; relationship building, business models. Article Classification: Research paper
Unpacking the efficacy of Reading to Learn using Cognitive Load Theory

This paper synthesises the key findings of two past separate studies conducted by the same authors, which sought to assess the efficacy of the Reading to Learn (RtL) literacy intervention on students’ academic writing performance. Both previous studies of RtL were implemented in response to growing concerns about the academic under-preparedness of undergraduate students at universities across South Africa. The first study aimed to support mostly firstgeneration, first-year English Additional Language (EAL) learners in their transition to higher education. The second study aimed to support EAL students’ academic writing development at a senior secondary school level prior to the school-to-university transition. In both studies, the cohorts of students examined originated from low socioeconomic communities, where linguistic marginalisation arguably imposes significant barriers to successful university completion. The novel contribution of this paper is to use a Cognitive Load Theoretical lens to explicate why RtL might improve the academic writing skills of under-prepared students making the transition to university.
Biotransformation of Furaltadone, Furazolidone and Nitrofurazone using Aspergillus Tamarii isolate TN-7 : in Vitro Residual Identification and Quantification by HPLC-DAD

Nitrofurans (NFs) such as furaltadone (FTD), furazolidone (FZD) and nitrofurazone (NFZ) have been used as antibacterials and growth promoters for the poultry and aquaculture industry. These antibiotics have now been banned from use due to their carcinogenic properties; therefore there is an urgent need to remove or degrade NFs from contaminated areas. Aspergillus tamarii isolate TN-7 isolated from antibiotic overexposed soil shows an ability to degrade the NFs antibiotics. After 5 days of incubating of Aspergillus tamarii isolate TN-7 with 500 μg/mL NF, the residual of the NF concentration was determined by High-Performance Liquid Chromatography-diode array detector (HPLC-DAD). Solid phase extraction was performed to clean-up the fermentation broth prior to HPLC-DAD analysis. Antimicrobial of the NFs residues showed a decreased in the percentage of inhibition that FTD, FZD and NFZ were reduced to to 85.71 %, 75.86 % and 70.97 % after 96 hours of incubation. Quantification using HPLC-DAD showed, after 96 hours of incubation, Aspergillus tamarii isolate TN-7 reduced furaltadone, furazolidone and nitrofurazone to 86.73 %, 37.49 % and 29.17 % respectively. This finding shows that Aspergillus tamarii isolate TN-7 has the potential to be used as a bioremediation tool in removing NF antibiotics from the contaminated areas.
The Role of Narratives in Collaborative Innovation – Transitions towards Relational Forms of Dementia Care

This article advances the relevance of a narrative approach in studies of collaborative innovation. The narrative approach outlined is based in translation theory, developed within science and technology studies (STS) and organizational studies. The research is based in a case study of an innovation initiative in municipal elderly care in Norway. The case study follows the implementation processes of the initiative in three elderly care institutions. Various forms of resistance were encountered in the implementation process, and the analysis shows how narrative strategies worked as brokering mechanisms in negotiations of this resistance. The article explores how a collaborative innovation process evolves through interplays between strategic narratives and counter narratives and contributes by demonstrating how narratives may work as important brokering mechanisms in collaborative innovation processes. The article discusses finally how and why narrative approaches may contribute to research on collaborative innovation, and it outlines managerial implications.
Cloning and Characterization of Centromeric DNA from Neurospora crassa

The centromere locus from linkage group VII of Neurospora crassa has been cloned, characterized, and physically mapped. The centromeric DNA is contained within a 450-kb region that is recombination deficient, A+T-rich, and contains repetitive sequences. Repetitive sequences from within this region hybridize to a family of repeats located at or near centromeres in all seven linkage groups ofN. crassa. Genomic Southern blots and sequence analysis of these repeats revealed a unique centromere structure containing a divergent family of centromere-specific repeats. The predominantly transitional differences between copies of the centromerespecific sequence repeats and their high A+T content suggest that their divergence was mediated by repeat-induced point (RIP) mutations.
The Relationship between Perceived Stress and Coping Strategies among Nurses in the Burn Care Unit at the Main Alexandria University Hospital

Nurses caring for burn injured patient had high stress levels in the workload and time pressure. The main stressful factors among burn injured patient care are high patients` death, emergency situations, and low supportive relationships. Prolonged stress without effective coping strategies may negatively contribute to the nurses’ quality of life and quality of care delivered. Aim of the study: Assess perceived stress and coping strategies among nurses caring for burn injured patient and to investigate the relationship between perceived stress and coping strategies among those nurses. Design: A descriptive correlational design was utilized for this study. Setting: The study was conducted in burn unit at Main Alexandria University hospital. Subjects: All nurses are working in burn care unit (45 nurse) were included in the study. Tools: Socio-demographic and work characteristics interview schedule, Perceived Stress and Brief Cope Scale. Results: Results of the study revealed that, more than half of the studied nurses had moderate level of perceived stress and rest of them having high level. The majority of the studied nurses had moderate level of problem-focused, emotion focused and dysfunctional coping strategies. A positive statistical significant relationship between nurses' perceived stress and behavioral disengagement & self blame coping strategies and a negative statistical significant relationship between perceived stress and active coping & planning, seeking emotional support and positive reframing coping strategies were found. Conclusion & recommendations: Perceived stress among studied nurses negatively related to problem- focused & emotion- focused coping strategies and positively related to dysfunctional coping strategies. Based on the findings, it is recommended to implement programs to tackle nurses’ stress level and improve their coping skills.
