A Tale of Hidden Cities

Hidden cities within a city? During the last decade there is a large trending literature concerning urban and suburban poverty concentration patterns. However, few are the cases where adequate data exist at a low spatial level, in order for scientists to explore that kind of socio-spatial phenomena. This paper tries to investigate the evolution of poverty within urban and suburban space, under a multidimensional framework, during a period of severe economic crisis and austerity measures. The metropolitan area of Athens is used as our case study, for which available data at a municipal level enable the calculation of the Multidimensional Poverty Index (MPI) for the years 2006 and 2011. Using cluster analysis based on the MPI values, three groups of municipalities are derived within Athens. For each one of them, a mean MPI index is calculated and then decomposed. The results indicate that there is a clear spatial concentration of poverty in the west suburban areas of Athens. The urban core of the city is characterised by middle-income municipalities, whilst the north-east and the south-east suburban areas experience low-poverty indicators. Finally, the results suggest that during the economic crisis period poor areas were affected the most.
Relations Among Poor Sleep, Anxiety and Depression Among the Students of Health Sciences

Abstract The research in the area of health sciences students’ sleep quality and mood disorders is lacking in Lithuania, as well as other European countries. The aim of this study was to compare prevalence of poor sleep, anxiety and depression among the students according to the study programmes and to assess the relations among poor sleep, depression and anxiety. The study sample consisted of 672 Klaipeda State University of Applied Sciences students (95.5% were female), from 18 to 46 years of age. Sleep quality was evaluated by Pittsburgh Sleep Quality Index, anxiety by Hospital Anxiety and Depression Scale, sociodemographic questions were used. The chi-square test or Fisher exact test was used to estimate association between categorical variables. P-values less than 0.05 were interpreted as statistically significant. Poor sleep was more prevalent among Beauty Therapy (26.4%, 95% CI 22.2-30.56) and Nursing (21.3%, 95% CI 17.42 – 25.17) students, as compared with persons studying in Oral Health programmes (14.8%, 95% CI 11.46 – 18.17), p<0.05. Depression mean score was higher in Beauty Therapy students (4.76), as compared to Oral Health (3.69) students, p<0.05. Beauty Therapy (9.99) or Physiotherapy students (8.24) had higher anxiety mean score, as compared to Oral Health students (7.14), p<0.05. Anxiety mean score was significantly higher (8.45) among the ones with disturbed sleep, as compared to normally sleeping students (5.86), p<0.001. Depression mean score (4.77) was higher among the students having disturbed sleep, as compared to the students which sleep was not disturbed (2.87), p<0.001. Poor sleep and anxiety were more prevalent among the students aged 20 years and older as compared to the students, aged 18 and 19 years. Second and third year students more often had poor sleep or anxiety as compared to the first-year students. Poor sleep and anxiety were more common among Beauty Therapy and Physiotherapy students than among Oral Health Students. Among the students who slept poorly, symptoms of anxiety and depression were statistically significantly more frequent than those students whose sleep was not disturbed. Depression and anxiety mean scores were statistically significantly higher among the students who had poor sleep, as compared to the ones who had normal sleep, in all age and year of studying groups.
An overview of the Odin atmospheric mission

Odin is a 250 kg class satellite built in co-operation between Sweden, Canada, France, and Finland and launched in February 2001. It carries two instruments: a 4-band sub-millimetre radiometer used for both astronomy and atmospheric science and an optical spectrometer and infrared imaging system for purely atmospheric observations. As part of the joint mission Odin will observe the atmospheric limb for 50% of the observation time producing profiles of many species of interest in the middle atmosphere with a vertical resolution of 1-2 km. These species include, among others, ozone, nitrogen dioxide, chlorine monoxide, nitric acid, water vapour, and nitrous oxide. An overview of the mission and the planned measurements is given.
Ocean acidification reduces mechanical properties of the Portuguese oyster shell with impaired microstructure: a hierarchical analysis

Abstract. The rapidly intensifying process of ocean acidification (OA) in coastal areas due to anthropogenic CO2 is not only depleting carbonate ions necessary for calcification but also causing acidosis and disrupting internal pH homeostasis in several marine organisms. These negative consequences of OA on marine communities, particularly to shellfish oyster species, has been very well documented in recent studies, however, the consequences of these reduced or impaired calcification processes on the end-product, shells or skeletons, still remains one of the major research gaps. Shells produced by marine organisms under OA are expected to be corroded with disorganized or impaired crystal orientation or microstructures with reduced mechanical property. To bridge this knowledge gap and to test the above hypothesis, we investigated the effect of OA on shell of the commercially important oyster species (Crassostrea angulata) at ecologically and climatically relevant OA levels (using pH 8.1, 7.8, 7.5, 7.2 as proxies). In decreased pH conditions, a drop of shell hardness and stiffness was revealed by nanoindentation tests, while an evident loosened internal microstructure was detected by scanning electron microscopy (SEM). In contrary, the crystallographic orientation of oyster shell showed no significant difference with decreasing pH by Electron Back Scattered Diffraction (EBSD) analyses. These results indicate the loosened internal microstructure may be the cause of the OA induced reduction in shell hardness and stiffness. Micro-computed tomography analysis (Micro-CT) indicated that an overall "down-shifting" of mineral density in the shell with decreasing pH, which implied the loosened internal microstructure may run through the shell, thus inevitably limiting the effectiveness of the shell defensive function. This study surfaces potential bottom-up deterioration induced by OA on oyster shells, especially in their early juvenile life stage. This knowledge is critical to forecast the survival and production of edible oysters in future ocean.
Uniform in Bandwidth Tests of Specication for Conditional Moment Restrictions Models

This paper addresses the issue of detecting misspecication on models dened by conditional moment restrictions (CMR). We propose new and practical specication tests built following either an approach a la Hausman (1978) or a score-type approach, see, e.g. Godfrey (1988). We show that both tests statistics are asymptotically equivalent, asymptotically chi-squared under the null hypothesis, and we derive their asymptotic power properties under a xed and a sequence of local alternatives. The asymptotic behavior of the tests obtain uniformly in the bandwidth. To approximate the statistical behavior of our general tests in small and moderate samples, we propose bootstrap procedures to compute their critical values. To our knowledge this is the rst general bootstrap proposed to date for specication testing in nonlinear models dened by CMR. The tests statistics and the bootstraps are simple to implement and simulation results show that they perform well in small samples.
Effect of Syngas Moisture Content on the Emissions of Micro-Gas Turbine Fueled with Syngas/LPG in Dual Fuel Mode

Syngas produced by gasification has a potential to be one of the fueling solutions for gas turbines in the future. In addition to the combustible constituents and inert gases, syngas derived by gasification contains a considerable amount of water vapor which effect on syngas combustion behaviour. In this work, a micro-gas turbine with a thermal capacity of 50 kW was simulated using ASPEN Plus. The micro gas turbine system emissions were characterized using dry syngas fuels with a different composition, syngas 1 (10.53% H 2 , 24.94% CO, 2.03% CH 4 , 12.80% CO 2 , and 49.70% N 2 ) and syngas 2 (21.62% H 2 , 32.48% CO, 3.72% CH 4 , 19.69% CO 2 , and 22.49% N2) mixed with LPG in a dual fueling mode. The effect of syngas moisture content was then studied by testing the system with moist syngas/LPG with a moisture content ranging from 0 to 20% by volume. The study demonstrates that the syngas moisture content has high influence on nitrogen oxides and carbon monoxide emissions. It’s found that for 5% syngas moisture content, the NOx emission were reduced by 75.5% and 83% for Syngas 1 and Syngas 2 respectively. On carbon monoxide emissions and for same moisture content ratio, the reduction was found to be 43% and 57% for syngas1 and syngas 2 respectively.
Copper Oxide Nanoparticles Stimulate Cytotoxicity and Apoptosis in Glial Cancer Cell Line

Due to cytotoxic potential, Copper Oxide Nanoparticles (CuO NPs) have recently been studied in various in vivo and in culture cell line. Also, CuO has received much attention in cancer therapy. We aimed to evaluate the cytotoxicity of CuO NPs on glial cancer (B92) cell line. B92 cancer cells were cultured with CuO NPs at different concentrations (5, 10, and 20 μg/ml) with 30 and 60 nm particle size. Then, cancer cells were incubated for 24 hrs. The apoptosis and cytotoxicity of cells were estimated by acridine orange/propidium iodide staining and MTT assay, respectively. Both sizes of CuO NPs had cytotoxic effect. Even with the lowest concentration, the cytotoxic impact accommodated 32% of cell apoptosis with 30 nm size. When the concentration of CuO NPs increased, viability decreased and apoptosis increased. However, these amounts have no significant changes in the concentration of 10 to 20 μg/ml between two particle sizes (30 and 60 nm). The IC50 was decreased as the size of particles increased, but there was no significant change. This finding suggests that exposure to CuO NPs had significant cytotoxic effect with the sizes tested when compared to unexposed control in a way that the smaller size and higher concentration exerted the maximum cytotoxic effects. It seems that augmentation may not have any impact on their in vitro cytotoxicity.Dhaka Univ. J. Pharm. Sci. 17(1): 105-111, 2018 (June)
XP-Antarctik Expedition: The Effect of a Month-Long Expedition in Antarctica on Physiological Performance

Antarctica is a challenging habitat for humans. A group of 6 explorers (3 women and 3 men) participated in an expedition in Antarctica. The objective was to observe the physiological acclimatization of the explorers using the following strategies: physical preparation, highcaloric nutritional intake, and the latest physiological monitoring and outdoor equipment. Anthropometric measures (dual x-ray absorptiometry), specific maximal aerobic test, maximal aerobic running speed test, submaximal aerobic cold testing, strength tests (grip strength, leg press and chin up), and endurance tests (bar suspension and chair position) were conducted preand post-expedition. Due to the sample size, a paired t-test was used for normally distributed data and non-parametric (Wilcoxon) to compare values preand post-expedition. Effect sizes are presented as Cohen’s d. The lean mass for the women was significantly higher after the expedition (45.4 ¡ 4.4 vs. 47.1 ¡ 4.1 kg; p 5 0.040, d 5 1.86); however, no significant difference was observed for the men (66.7 ¡ 7.3 vs. 66.0 ¡ 5.7 kg; p 5 0.581, d 5 0.11). Preand post-expedition values were significantly different for the specific maximal aerobic test, where the VO2peak was 40.8 ¡ 4.2 vs. 46.9 ¡ 7.4 ml/kg/min, respectively (p 5 0.027, d 5 1.01), but no significant difference was observed for the other aerobic tests. The muscular testing did not change significantly, except for the left leg one maximal repetition (295 ¡ 110 vs. 364 ¡ 135 lb, preand post-expedition respectively, p 5 0.031, d 5 20.56). The overall preparation for the expedition appears to be a key aspect in order to countermeasure the physical ability decay during an Antarctica expedition. However, further studies will need to be developed to discern the importance of the preparation components.
Silence in organizations and psychological safety : a literature review

In the business world, employees can contribute with information, ideas, concerns, opinions and proposals to their managers in respect of: (1) the way work could be performed, (2) what should / should not be done in the workplace, (3) how a particular decision can be implemented, and (4) how an organizational policy should be formed and executed (Rego, 2013). However, due to a diverse set of factors, employees often choose to remain silent in the workplace. One of these factors is psychological safety, which describes employees’ perceptions of the consequences of taking interpersonal risks in the workplace (Edmondson, 2014). The following paper is essentially a literature review and its aim is to, firstly, make a brief approach to factors reported in the literature that may affect employee voice and silence, followed up by an explanation of the types of silence that can be engaged by employees. Besides that, the authors will also make an approach to physical and psychological safety. Lastly, it will be reported some links, mentioned in the literature, between employee silence and psychological safety.
Colloidal photonic crystal modified optical fiber and relative humidity detection application

This paper propose a route to decorated end facet of single mode optical fibers with colloidal photonic crystals and present the principle for this structure to be used as relative humidity sensing. The approaches of preparing PS colloidal crystals, composite colloidal crystals, and SiO2 inverse opals on the end faces of optical fibers by vertical deposition was studied. The prepared colloidal crystals and inverse opal were structurally characterized, and the reflection spectra of the photonic crystals-modified microstructure optical fibers was measured. The relative humidity sensing characteristics of composite photonic crystals decorated microstructure optical fibers were tested. Finally, a capillary-fiber structure was proposed to improve the quality and mechanical stability of the colloidal crystals fabricated on the fiber endfaces.
Low-carbon practices: a third sector research agenda

Developing a low carbon society will require significant transformations of everyday lives. Academic and policy actors have suggested that third sector organisations (TSOs) can play an important role in the transition to a low carbon society. Whilst there is some empirical evidence that third sector organisations can successfully encourage changes in everyday practices, their role is not yet well understood. As part of the TSRC programme of research, our aim is to better understand the potential contribution of TSOs. This paper reviews different conceptions of behaviour and practice change and provides an overview and analysis of the literature on the role of TSOs in promoting change. We then offer a social practice framework that will guide empirical research into the types of interventions undertaken by TSOs and the different barriers that confront change
Two Transmissible Plasmids in Rhizobium leguminosarum strain 300

SUMMARY: The transposon Tn5, which specifies kanamycin resistance, was inserted into transmissible plasmids of Rhizobium leguminosarum strain 1062, a derivative of strain 300. In this way several kanamycin-resistant derivatives of the two smallest plasmids (pRL8JI and pIJ1001) were obtained, but there was no evidence that any of the other plasmids of strain 1062 was transmissible. Kanamycin-sensitive derivatives, each apparently cured of either pRL8JI or pIJ1001, still induced nitrogen-fixing nodules on peas and were not phenotypically distinct from the parental strain. Both plasmids were transmissible at low frequency to other R. leguminosarum strains, but they could be mobilized efficiently by pRLlJI, another transmissible R. leguminosarum plasmid. When Tn5-marked pIJ1001 was transferred to a strain of R. phaseoli, the majority of the transconjugants lost the ability to nodulate Phaseolus beans, the normal host for this species. This was due to the loss from R. phaseoli of a nodulation plasmid which was apparently incompatible with pIJ1001.
Ability of Slovakian Pupils to Identify Birds.

A pupil’s ability to identify common organisms is necessary for acquiring further knowledge of biology. We investigated how pupils were able to identify 25 bird species following their song, growth habits, or both features presented simultaneously. Just about 19 % of birds were successfully identified by song, about 39 % by growth habit, and 45 % of birds were identified when pupils were allowed to hear their song and to see their growth habit simultaneously. Statistically significant correlation was found between visual and acoustical identification success which suggests that these two stimuli have an additive effect. This study provides direct support for the use of visual and acoustic features of animals when learning about birds in biology lessons.
Spatial dynamics of virus-like particles and heterotrophic bacteria within a shallow coral reef system

Variations in the abundance and community characteristics of virus-like particles (VLP) and heterotrophic bacteria within a shallow, near-shore coral reef were determined using flow cyto- metric analysis. Mean concentrations of 6.5 × 10 5 and 1.3 × 10 5 ml -1 were observed for VLP and bac- terioplankton, respectively, although concentrations of both populations varied significantly (p < 0.05) between 4 distinct reef water types. Significant (p < 0.05) variability in the percentage of high DNA (HDNA) bacteria, applied here as an estimate of the proportion of active bacterial cells, and the virus:bacteria ratio (VBR) was also observed between different reef water types. Microscale profiles were taken in the 12 cm layer of water directly above the surface of coral colonies to determine the small-scale spatial relationships between coral colonies and planktonic microbial communities. Across these profiles, mean changes of 2- and 3.5-fold were observed for bacterioplankton and VLP communities, respectively, with VLP abundance positively correlated to bacteria in 75% of profiles. Bacterial and VLP abundance, percentage of HDNA bacteria, and VBR all generally exhibited increasing trends with proximity to the coral surface. VLP abundance was significantly higher (p < 0.05) in the 4 cm closest to the coral surface, and the VBR was higher at the coral surface than in any other zone. The patterns observed here indicate that VLP represent an abundant and dynamic com- munity within coral reefs, are apparently coupled to the spatial dynamics of the bacterioplankton community, and may consequently significantly influence nutrient cycling rates and food-web struc- ture within coral reef ecosystems.
Penn State Worry Questionnaire-11 validity in Colombia and factorial equivalence across gender and nonclinical and clinical samples

The Penn State Worry Questionnaire (PSWQ) is the gold standard measure of the unspecific worry that characterizes generalized anxiety disorder. This study aims to explore the validity of the PSWQ in Colombia and its measurement invariance across gender and clinical and nonclinical participants. An abbreviated, 11-item version of the PSWQ by Sandín, Chorot, Valiente, and Lostao (2009) was used because the negatively worded items have shown to be problematic for Spanish speakers. Additionally, research has suggested that the negatively worded items of the PSWQ lack of practical utility. The PSWQ-11 was administered to a total of 1045 participants, including a sample of nonclinical participants (N = 710) and a sample of clinical participants (N = 335). The internal consistency of the PSWQ-11 across samples was excellent. The one-factor model showed an acceptable fit to the data. Metric and scalar invariance were observed across gender and clinical and nonclinical samples. In conclusion, the PSWQ-11 seems to be a valid measure of GAD-related worry in Colombia, whereas data on factorial equivalence data warrant the comparison of scores across gender and clinical and nonclinical samples.
Molybdenum disulfide / mesoporous carbon nanocomposite as electrode material for supercapasitors

The article describes the features of MoS 2 /mesoporous carbon nanocomposite creation and application as an electrode material for hybrid supercapacitors. The combination of these two materials improved the electrochemical characteristics in comparison with molybdenum disulphide or mesoporous carbon on their own; in particular the synergetic effect between them led to the reduction of internal resistance and increase of electric conductivity that are reflected in the maximum power of the capacitor. In spite of a large surface area of the mesoporous carbon obtained from the raw material of plant origin (2200 m 2 g –1 ), the synthesized nanocomposite (430 m 2 g –1 ) has almost twice higher specific capacity (57 Fg –1 and 110 Fg –1 , respectively) due to the summary effect of EDL and faradaic processes in the material. The samples were characterized by X-ray difractometry (XRD), transmission electron microscopy (TEM), porosimetry, impedance spectroscopy, voltammetry, and chronopotentiometry.
