Analytical investigation of single and double Neimark-Sacker bifurcations

The analytical investigation of bifurcations is a very challenging task for many applied scientists and engineers. Often, numerical simulations cannot clarify the complicated dynamics of mechanical systems, in this cases, preprogrammed softwares can be of valid help during the investigation. Also, in the literature, methodology to study bifurcations are presented for most of the cases. However, the presented procedures, are often very hard to be understood from applied scientists with low mathematical background. In this paper we present in details the typical procedure to analyze single and double Neimark-Sacker bifurcations. Especially regarding the double Neimark-Sacker bifurcations of maps, very few sources can be found in the literature, although this kind of bifurcation is very common in many dynamical systems.
Nitrogen-containing secondary organic aerosol formation by acrolein reaction with ammonia/ammonium

Abstract. Ammonia-driven carbonyl-to-imine conversion is an important formation pathway to the nitrogen-containing organic compounds (NOCs) in secondary organic aerosols (SOAs). Previous studies have mainly focused on the dicarbonyl compounds as the precursors of light-absorbing NOCs. In this work, we investigated whether acrolein could also act as an NOC precursor. Acrolein is the simplest α, β-unsaturated mono-carbonyl compound, and it is ubiquitous in the atmosphere. Experiments probing multiphase reactions of acrolein as well as bulk aqueous-phase experiments were carried out to study the reactivity of acrolein towards ammonia and ammonium ions. Molecular characterization of the products based on gas chromatography mass spectrometry, high-resolution mass spectrometry, surface-enhanced Raman spectrometry and ultraviolet/visible spectrophotometry was used to propose possible reaction mechanisms. We observed 3-methylpyridine (commonly known as 3-picoline) in the gas phase in Tedlar bags filled with gaseous acrolein and ammonia or ammonium aerosols. In the ammonium-containing aqueous phase, oligomeric compounds with formulas (C3H4O)m(C3H5N)n and pyridinium compounds like (C3H4O)2C6H8N+ were observed as the products. The pathway to 3-methylpyridine was proposed to be the intramolecular carbon–carbon addition of the hemiaminal, which resulted from sequential carbonyl-to-imine conversions of acrolein molecules. The 3-methylpyridine was formed in the aqueous phase, but some of the 3-methylpyridine could revolatilize to the gas phase, explaining the observation of gaseous 3-methylpyridine in the bags. The (C3H4O)2C6H8N+ was a carbonyl-to-hemiaminal product from acrolein dimer and 3-methylpyridine, while the oligomeric products of (C3H4O)m(C3H5N)n were polymers of acroleins and propylene imines formed via carbonyl-to-imine conversion and condensation reactions. The pH value effect on the liquid products was also studied in the bulk aqueous-phase experiments. While the oligomeric compounds were forming in both acidic and alkaline conditions, the pyridinium products favored moderately acidic conditions. Both the oligomeric products and the pyridinium salts are light-absorbing materials. This work suggests that acrolein may serve as a precursor of light-absorbing heterocyclic NOCs in SOA. Therefore, secondary reactions of α, β-unsaturated aldehydes with reduced nitrogen should be taken into account as a source of light-absorbing NOCs in SOA.

Contaminant Extractability by Electrokinetics

Electrokinetic extraction is an emerging technology that has shown considerable potential for efficient and effective removal of both inorganic and organic contaminants from fine-grained soils of low hydraulic conductivity and large specific area when conditions are favorable. The cleanup technology is basically the application of a direct-current electric field across contaminated soils through electrodes installed in the subsurface. The contaminant is removed by (1) electro-osmotic advection of pore fluid flushing the contaminants; (2) ionic migration or electromigration of contaminants carrying charges; and (3) electrophoresis of charged colloidal-sized particles carrying contaminants. However, many complicated electrochemical phenomena that can change the electrokinetic properties of soil particles and the chemistry of pore fluid occur simultaneously. The resulting soil–chemical interactions may enhance or inhibit the extractability of contaminants by electrokinetics, as various electrochemical proces.
An evaluation of the repatriation process at Company X

Many companies today have parts of their organizational activity abroad. By having subsidiaries in a foreign country, employees prepared to transfer abroad are required. Transferring employees abroad is not a new phenomenon; however, it is done more extensively today. Even though expatriation has been around quite some time, companies are still struggling with parts of the process, especially the last part of it, repatriation. In this study, an evaluation of Company X’s repatriation process is conducted, and from our findings, recommendations are made. The study is based on relevant theories that we feel support the empirical data collection. The data collection is made through interviews and is further analyzed and discussed in order to support our findings. The main areas discussed related to repatriation in this thesis are: reverse culture shock, mentors, career development, proactive behavior, communication, and finally evaluation. A more general conclusion is provided as well as recommendations for Company X on how to deal with the process of repatriation.
X-ray emission of interacting wind binaries in Cyg OB2

Cyg OB2 #5, #8A, and #9 are binary or multiple massive stars in the Cyg OB2 association displaying several peculiarities, such as bright X-ray emission and non-thermal radio emission. Our X-ray monitoring of these stars reveals the details of their behaviours at high energies, which can be directly linked to wind-wind collisions (WWCs). In addition, the X-ray emission of Cyg OB2 #12, an evolved massive star, shows a long-term decrease, which could hint at the presence of a companion (with associated colliding winds) or indicate the return to quiescence of the star following a recent eruption.
Light Scattering by Quasi-Spherical Ice Crystals

Abstract The shapes and single-scattering properties of small, irregular, quasi-spherical ice crystals, with equivalent radii between approximately 8 and 90 μm and size parameters from about 90 to 1000, are studied using two-dimensional images measured by a cloud particle imager in midlatitude cirrus during the 2000 Cloud Intensive Operation Period conducted over the Atmospheric Radiation Measurement program's Southern Great Plains site. A statistical shape analysis of the ice crystal images is carried out to obtain size-dependent relative standard deviations of radius and correlation functions of logradius, which together define the shape statistics of the sample ice crystals. The former describes the overall variation in the lengths of radius vectors defining the particle surface from a given origin, whereas the latter describes correlations of lengths of radius vectors as functions of angular distance between them. The logradius is essentially the natural logarithm of radius. There is no strong depende.
Socio-Economic Inequalities in the Risk of Diseases and Associated Risk Factors in India

Extant literature is full of studies on socio-economic inequalities in maternal and child health in India but studies on inequalities in risk of diseases are limited. We use data from India Human Development Survey (IHDS) conducted in 2004-05 to test two hypotheses: first, diabetes and high blood pressure are associated with affluence; and second, tuberculosis and mental illness are associated with poverty. We use rich-poor ratio, concentration curves, adjusted concentration indices, dominance test, and binary logistic regression to test the aforementioned hypotheses. The findings suggest that diabetes and high blood pressure are indeed associated with affluence. But we could not find evidence to support our second hypothesis. Also, rich and poor were equally likely to get cancer or the heart diseases. Indeed, the risk factors were disproportionately distributed, particularly to the disadvantage of the poor.
Medicinal and aromatic plants production under salt stress. A review

Salinization of soils or waters is one of the world’s most serious environmental problems in agriculture. It is necessary to determine the environmental factors under which medicinal and aromatic plants give higher yields and better quality. The problem of salinity is characterized by an excess of inorganic salts and is common in the arid and semi-arid lands, where it has been naturally formed under the prevailing climatic conditions and due to higher rates of evapotranspiration and lack of leaching water. Although more frequent in arid lands, salt-affected soils are also present in areas where salinity is caused by poor quality of irrigation water. Saline soil induces physiological and metabolic disturbances in plants, affecting development, growth, yield, and quality of plants. Plants affects adversely as a result of salinity, seed germination, survival percentage, morphological characteristics, development and yield and its components. In general, salt stress decreases the photosynthesis and respiration rate of plants. Total carbohydrate, fatty acid and protein content were adversely affected due to salinity effect, but increased the level of amino acids, particularly proline. The content of some secondary plant products is significantly higher in plants grown under salt stress than in those cultivated in normal conditions. The salinity tolerance depends on the interaction between salinity and other environmental factors.
Virtual Negotiations between Collocated Diverse Teams : The Effect of Intragroup Faultlines on Intergroup Communication

This work examines the effect of faultlines in virtual computer mediated communications of two collocated negotiation teams. We expand upon prior diversity literature by considering the effect of both surface and deep-level faultlines on the intergroup computer mediated communications in virtual negotiations. Faultlines are hypothetical lines that divide teams into multiple subgroups based on diversity attributes. We confirm that the effect of team diversity on intergroup computer mediated communications can be better captured through faultlines. Our results suggest that faultlines mediate the effect of diversity on teams’ computer mediated intergroup communication and that deep-level faultlines significantly lower the frequency and quality of intergroup communication of virtual negotiations.
Emotional Intelligence of Late Adolescent Girls Belonging to Nuclear and Joint Family

The present study was an attempt to assess and compare the emotional intelligence of late adolescent girls residing in nuclear family and joint family. The total sample for the present study consisted of N= 120 late adolescent girls (n=60 nuclear family and n=60 joint family). The sample was selected from 3 non coeducational government schools of Udaipur city. A preliminary survey was conducted among 11th and 12th class students to select the sample as per the delimitation of the study. To assess emotional intelligence, Mangal’s emotional intelligence inventory (2004) was administered. Four dimension of emotional intelligence namely intrapersonal awareness, interpersonal awareness, intrapersonal management and interpersonal management were also assessed. The data was collected, coded and analyzed. Frequency and percentage was computed for each category.
Finite Element Modeling and Physical Property Estimation of Rheological Food Objects

The purpose of this study is to accurately simulate the rheological behaviors of food objects undergoing a loading-unloading operation using finite element (FE) model. Due to the presence of residual deformation, it is difficult to model rheological behaviors. Especially, it is hard to accurately reproduce both rheological force and residual deformation simultaneously. In this study, objects made of food materials were tested. Force and deformation measurements were recorded for parameter estimation. Constitutive models were investigated for describing rheological behaviors. A parallel five-element model including two dual-moduli viscous elements was proposed to accurately predict both rheological force and residual deformation simultaneously. 2D/3D FE model was formulated for simulating rheological behaviors. To estimate the parameters, an effective four-step method was established based on nonlinear optimization which aimed at minimizing the differences of forces and deformation between simulation and experiments. The proposed FE model and parameter estimation method were validated in both 2D and 3D cases and good agreements were achieved in both rheological forces and deformation between numerically simulated and experimentally measured data.
Relationship between Dietary Diversity and Haematological Status of Children aged 659 months in Northern Ghana Running Head : Dietary Diversity and Child ’ s Haematological Status

Background: Though a number of studies have shown that dietary diversity is related to nutritional adequacy, little is known about the extent dietary diversity contributes to the haematological status of children aged 6-24 months. The aim of this study was to assess the independent contribution of dietary diversity to haematological status of children aged 6-59 months whilst controlling for potential confounding factors including malarial infection. Methods: A community-based cross-sectional survey was conducted. A stratified Probability Proportionate to Population Size (PPS) approach was applied to select the study clusters. The association between dependent variable (anaemia) and independent variables was determined using both bivariate and multiple logistic regression modeling. Results: The mean haemoglobin concentration among the children studied was 10.2 g/dl ± 1.42 and an overall prevalence of anaemia was 68.7% (CI: 65.1, 72.0). Minimum diet diversity was associated with adequate haematological status among only children who were at least three years but not in children less than three years. Children aged at least three years who met minimum diet diversity (4+ food groups) were 45% less likely of becoming anaemic (AOR= 0.55, 95% CI: 0.31 0.98), compared to their counterparts who did not meet minimum diet diversity (<4 food groups). Conclusions: Minimum dietary diversity independently protects against anaemia among children 36-59 months but this was not discernible among children 6-35 months in Northern Ghana.
‘MINDtouch’ — embodied ephemeral transference: Mobile media performance research

ABSTRACT The aim of the author's media art research has been to uncover any new understandings of the sensations of ‘liveness’ and ‘presence’ that may emerge in participatory networked performance, using mobile phones and physiological wearable devices. To practically investigate these concepts, a mobile media performance series was created, called ‘MINDtouch’. The MINDtouch project proposed that the mobile videophone become a new way to communicate non-verbally, visually and sensually across space. It explored notions of ephemeral transference, distance collaboration and participant as performer to study ‘presence’ and ‘liveness’ emerging from the use of wireless mobile technologies within real-time, mobile performance contexts. Through participation by in-person and remote interactors, creating mobile video-streamed mixes, the project interweaves and embodies a daisy chain of technologies through the network space. As part of a practice-based Ph.D. research conducted at the SMARTlab Digital Media Institute at the University of East London, MINDtouch has been under the direction of Professor Lizbeth Goodman and sponsored by BBC R&D. The aim of this article is to discuss the project research, conducted and recently completed for submission, in terms of the technical and aesthetic developments from 2008 to present, as well as the final phase of staging the events from July 2009 to February 2010. This piece builds on the article (Baker 2008) which focused on the outcomes of phase 1 of the research project and initial developments in phase 2. The outcomes from phase 2 and 3 of the project are discussed in this article.
Privacy Calculus in the Context of the GeneralData Protection Regulation and Healthcare: AQuantitative Study

This research looks at the effect of factors like risk and benefits on the decision of individuals to disclose personal information. As a theoretical framework, the privacy calculus is introduced and connected with the new GDPR regulations. The hypotheses stemming from this connection looks whether there is a significant effect of inherent and handled risk and expected quality of care on the decision to disclose personal information in a hospital setting. This setting revolves around the situation that a participant needs basic or major medical attention. Additionally, a baseline of general attitudes addressing subjects like trust in hospitals or companies and whether personal data is perceived as personal or private is established. The outcome of the survey that included 125 respondents, mainly from Germany or the Netherlands and being between 20 and 30 years old, supports that handled risk and the expected quality of care has a significant influence on the data disclosing decision within subjects. However, since the sample of the data is limited in reach concerning geography and age group no conclusion about the broader population can be made which leaves room for additional research.
Reducing Power Consumption of Measurement and Control Modules Fed with Autonomous Power Supply

In this paper, a detailed analysis is made of the possibility of reducing the energy consumption of the measuring and control modules when they are powered by an autonomous source, a battery, without the possibility of restoring its charge. These modules are designed, in particular, to work in the system for emergency and post-emergency monitoring of equipment and the territory of complex technical systems (for example, nuclear power plants), which must ensure a long (according to regulatory documents at least 72 hours) data and commands exchanging. The issue of saving energy consumption is considered: (i) at all levels of building measurement and control modules from wireless data interchange and commands at the level of the structure of the system as a whole to the structure of the most measurement-control modules and circuits of their nodes (ii) in the context of providing informativity, survivability and reliability of data exchange and commands in the system of emergency and post-emergency monitoring of equipment and the territory as a whole. It is shown that the use of modern technical elements (in particular, drones operating as data and instructions retransmitters) and structural solutions (in particular, calibration of analog-digital and digital-analog converters) enables to ensure a high reliability of data and commands exchange despite simplifying the structure of nodes for saving energy consumption.
Spatial and Temporal Distribution of Air Temperature over the Balkan Peninsula *

In this study the spatial and temporal distribution of the 5 x 5 gridded air temperature, over the Balkan Peninsula, (10E-30E, 35N-50N) are presented, using the Principal Components Analysis, (PCA). The goal of that research is to pinpoint the regionalization of Balkans concerning the covariability of surface air temperature. Eleven 5 x 5 grid box time series of air temperature, (annual and seasonal data), covering a period of 133 years (1858-1990) are grouped in three components representing the climatic characteristics of the North-West, South and North-East regions of the examined area. The spatial distribution of the grid box time series has the same pattern for the annual, winter and spring temperature variations, but differs for summer and autumn ones where the first principal component represents the North-East and South region respectively. Air temperature variations during the period 1858-1990 are also presented on a basis of the annual and seasonal time series of the scores for the significant principal components. Key-words: Air temperature, spatial and temporal distribution, Principal Components Analysis, Balkan peninsula. ¶∂ƒπ§∏æ∏: TMÙËÓ ÂÚÁ·Û›· · ̆Ù‹ ·ÚÔ ̆ÛÈ¿ ̇ÂÙ·È Ë ̄ˆÚÈÎ‹ Î·› ̄ÚÔÓÈÎ‹ Î·Ù·ÓÔÌ‹ ÙË ̃ ıÂÚÌÔÎÚ·Û›· ̃ ÙÔ ̆ ·¤Ú· ÎÈ‚ˆÙ›ˆÓ Ï¤ÁÌ·ÙÔ ̃ 5 x 5, ÁÈ· ÙËÓ μ·ÏÎ·ÓÈÎ‹ ̄ÂÚÛfiÓËÛÔ, (10∂ 30∂, 35¡ 50¡), ÂÊ·ÚÌfi ̇ÔÓÙ· ̃ ÙËÓ ∞Ó¿Ï ̆ÛË ÛÂ ∫‡ÚÈÂ ̃ TM ̆ÓÈÛÙÒÛÂ ̃ (PCA). √ ÛÎÔfi ̃ ÙË ̃ ¤ÚÂ ̆Ó· ̃ ‹Ù·Ó Ó· ·Ó·‰ÂÈ ̄ıÔ‡Ó ÂÚÈÔ ̄¤ ̃ ÙˆÓ μ·ÏÎ·Ó›ˆÓ Ô ̆ ·ÚÔ ̆ÛÈ¿ ̇Ô ̆Ó ÔÌÔÈfiÙËÙÂ ̃ ÛÙËÓ ÌÂÙ·‚ÏËÙfiÙËÙ· ÙË ̃ ÂÈÊ·ÓÂÈ·Î‹ ̃ ıÂÚÌÔÎÚ·Û›· ̃ ÙÔ ̆ ·¤Ú·. √È ̄ÚÔÓÔÛÂÈÚ¤ ̃ ÙË ̃ ıÂÚÌÔÎÚ·Û›· ̃ ÙÔ ̆ ·¤Ú· (ÂÙ‹ÛÈÂ ̃ Î·È ÂÔ ̄ÈÎ¤ ̃ ÙÈÌ¤ ̃) ·fi ¤ÓÙÂÎ· ÎÈ‚ÒÙÈ· Ï¤ÁÌ·ÙÔ ̃ 5 x 5, ÁÈ· ̄ÚÔÓÈÎ‹ ÂÚ›Ô‰Ô 133 ÂÙÒÓ (1858-1990) ÔÌ·‰ÔÔÈÔ‡ÓÙ·È ÛÂ ÙÚÂÈ ̃ Î‡ÚÈÂ ̃ Û ̆ÓÈÛÙÒÛÂ ̃, Ô ̆ ·ÓÙÈÚÔÛˆÂ‡Ô ̆Ó Ù· ÎÏÈÌ·ÙÈÎ¿ ̄·Ú·ÎÙËÚÈÛÙÈÎ¿ ÙÔ ̆ μÔÚÂÈÔ-∞Ó·ÙÔÏÈÎÔ‡ ÙÌ‹Ì·ÙÔ ̃ ÙË ̃ ÂÍÂÙ· ̇fiÌÂÓË ̃ ÂÚÈÔ ̄‹ ̃. ∏ ̄ˆÚÈÎ‹ Î·Ù·ÓÔÌ‹ ÙˆÓ ̄ÚÔÓÔÛÂÈÚÒÓ ÙË ̃ ıÂÚÌÔÎÚ·Û›· ̃ ÙÔ ̆ ·¤Ú· ¤ ̄ÂÈ ÙËÓ ›‰È· ÌÔÚÊ‹ fiÛÔÓ ·ÊÔÚ¿ ÙÔ ¤ÙÔ ̃, ÙÔÓ ̄ÂÈÌÒÓ· Î·È ÙËÓ ¿ÓÔÈÍË, ÂÓÒ ‰È·ÊÔÚÔÔÈÂ›Ù·È ÁÈ· ÙÔ ı¤ÚÔ ̃ Î·È ÙÔ ÊıÈÓfiˆÚÔ, fiÔ ̆ Ë ÚÒÙË Î‡ÚÈ· Û ̆ÓÈÛÙÒÛ· ·ÓÙÈÚÔÛˆÂ‡ÂÈ ÙÔ μfiÚÂÈÔ-∞Ó·ÙÔÏÈÎfi Î·È ¡fiÙÈÔ ÙÌ‹Ì· ÙˆÓ μ·ÏÎ·Ó›ˆÓ, ·ÓÙ›ÛÙÔÈ ̄·. √È ̄ÚÔÓÈÎ¤ ̃ ÌÂÙ·‚ÔÏ¤ ̃ ÙË ̃ ıÂÚÌÔÎÚ·Û›· ̃ ÙÔ ̆ ·¤Ú·, Î·Ù¿ ÙËÓ ‰È¿ÚÎÂÈ· ÙË ̃ ÂÚÈfi‰Ô ̆ 1858-1990, ÂÍÂÙ¿ ̇ÔÓÙ·È Â›ÛË ̃ ÛÙË ‚¿ÛË ÙˆÓ ÂÙ‹ÛÈˆÓ Î·È ÂÔ ̄ÈÎÒÓ ̄ÚÔÓÔÛÂÈÚÒÓ ÙˆÓ Î·ÓÎÓÈÎÔÔÈËÌ¤ÓˆÓ ÙÈÌÒÓ ÙˆÓ ÛËÌ·ÓÙÈÎÒÓ Î ̆Ú›ˆÓ Û ̆ÓÈÛÙÒÛˆÓ. §¤ÍÂÈ ̃-ÎÏÂÈ‰È¿: £ÂÚÌÔÎÚ·Û›· ·¤Ú·, ̄ˆÚÈÎ‹ Î·È ̄ÚÔÓÈÎ‹ Î·Ù·ÓÔÌ‹, ∞Ó¿Ï ̆ÛË ÛÂ ∫‡ÚÈÂ ̃ TM ̆ÓÈÛÙÒÛÂ ̃, μ·ÏÎ·ÓÈÎ‹ ̄ÂÚÛfiÓËÛÔ ̃.
Viscoelasticity of the bacterial cell envelope

Bacterial cell envelopes are remarkable biological structures that allow cells to adapt to and survive changes in their external environment while maintaining their mechanical integrity as the cells grow and divide. We review efforts to characterize the mechanical properties of the bacterial cell envelope, and we highlight recent advances in measurement techniques for individual bacterial cells that have led to a more complete understanding. In addition to their elastic behavior, bacterial cell walls also demonstrate a time dependent response to externally applied forces such that their mechanical properties are more properly described as viscoelastic. These measurements provide important information that is needed to understand the complex relationship between their structure and function.
