Measurement of vortex shedding in the wake of a sphere at $Re=465$

Flow in the wake of a sphere has been studied for at least the last hundred years. The three-dimensional (3-D) flow structure has been observed many times using dye visualization and prior to the direct numerical simulations by Johnson & Patel (J. Fluid Mech., vol. 378, 1999, pp. 19–70), its structure at a Reynolds number of approximately 300, was believed to consist of a one-sided chain of hairpin-like vortices. However, the numerical simulations by Johnson & Patel (J. Fluid Mech., vol. 378, 1999, pp. 19–70) also showed that so-called ‘induced’ vortices were generated. The present results are the first spatially resolved measurements that elucidate the 3-D vortex shedding cycle in the wake of a sphere at a Reynolds number of 465. Tomographic particle image velocimetry (tomo-PIV) enabled snapshots of the vortical structure and by combining these results with temporally resolved planar PIV, the ensemble averaged shedding cycle in the wake of the sphere was reconstructed. The present results clearly indicate that besides the ‘primary’ vortex chain shed from the sphere, secondary (‘induced’) vortices are generated by transforming transverse vorticity into streamwise vorticity as a result of the interaction between the sphere’s separating shear layer and the counter-rotating longitudinal vortices extending downstream from the sphere.
A Cross-national Study: Using Face-Negotiation Theory to Understand Gender, Commitment and Culture in Coping Strategies toward a Partner's Infidelity

The current study explored coping strategies toward the context of discovering a partner’s sexual infidelity. There were two primary goals for the current study. First, the current study examined the gender and national differences in conflict styles toward the context of discovering a partner’s sexual infidelity. Second, the current study examined the relationship between face concerns and commitment. There were national and gender differences on self-construal face concern, face-concern and conflict styles in the current study. The current findings also suggested that face concern is moderating the relationship between commitment and conflict styles. The limitation and future directions were discussed as well as the clinical implications in the current study.

Spiritual Intelligence Relationship with Organizational Citizenship Behavior and Commitment of School Teachers

Introduction: In an educational organization, because of its important function in human resources development and training in the community, respecting the values, spirituality, leadership, and management strengthening, based on spirituality and good citizenship behavior and commitment have greater importance. Aim: This study examined the relation between spiritual intelligence with organizational citizenship behavior and organizational commitment of secondary school teachers. Methods: The research method was correlational and its population included all teachers in education districts 2 and 5 in 2015 from which 358 teachers were selected by using Cochran formula and simple random sampling method as a sample. To collect data, three questionnaire: the King Spiritual Intelligence questionnaire (2007) and Padasakof et al. citizenship behavior questionnaire (2000) and organizational commitment questionnaire of Meyer (2001)were used . The reliability of the tools obtained by Cronbakh Formula 0/85,0/84, 0/7 respectively. For statistical analysis, the descriptive statistics (average, percentage, Standard deviation) and inferential statistical tests (Kolmogorov - Smirnov test, Pearson correlation coefficient test and stepwise regression analysis) were used. Conclusion: The results showed that none of the components of citizenship behavior has a significant relation with a critical thought component of spiritual intelligence. Regarding the personal meaning making component of spiritual intelligence, only the components of sportsmanship and social customs have a significant relation, and other components have no significant association. All components of citizenship behavior are significantly associated with a transcendental consciousness component of spiritual intelligence and have no significant relation with self-awareness extends component. None of the organizational commitment components have a significant relation to the critical thinking component and high awareness of spiritual intelligence and only the emotional commitment of the organizational commitment component have a significant relation with the personal meaning making of spiritual intelligence, as well as with the expansion of consciousness component.
Design and development of hand gesture recognition system for speech impaired people

All over world, deaf and dumb people face struggle in expressing their feelings to other people. There are various challenges experienced by speech and hearing impaired people at public places in expressing themselves to normal people. The solution to this problem is determined in this paper, by the usage of the Indian sign language symbols which are generic to all deaf and dumb people in India. The gestures illustrated by the Indian sign language symbols will be conquered with the support of the flex sensors and accelerometer. The movements included during gesture representation are rotation, angle tilt, and direction changes. The flex sensor and the accelerometer are incorporated over fingers and wrist respectively to acquire their dynamics, a these sensors are fitted over the data glove. These voltage signals will then be processed by microcontroller and sent to voice module, where the words voice outputs are stored and play backed equivalent to each word values to produce the appropriate voice words with the help of the speaker.
Deterioration of Vestibular Cells in Labyrinthitis

Objective: To quantitatively assess the effect of serous labyrinthitis, suppurative labyrinthitis, and labyrinthitis ossificans on vestibular hair cells, dark cells, and transitional cells. Methods: We examined human temporal bone specimens with serous labyrinthitis, suppurative labyrinthitis, and labyrinthitis ossificans, then compared them with age-matched control groups without labyrinthitis. We evaluated the density of type I and II vestibular hair cells, dark cells, and transitional cells in the peripheral sensorial organs. Results: The mean density of type I vestibular hair cells in the maculae of the saccule significantly differed between the serous labyrinthitis group and its control group. The loss of type I and II vestibular hair cells in all of the peripheral sensorial organs was significantly higher in the suppurative labyrinthitis group than in its control group. The mean density of dark cells in the lateral and posterior semicircular canals was significantly lower in the suppurative labyrinthitis group than in its control group. The mean density of type I and II vestibular hair cells, dark cells, and transitional cells was significantly lower in the labyrinthitis ossificans group than in its control group. Conclusion: The loss of vestibular hair cells and degenerative changes in dark cells and transitional cells could affect vestibular function in patients with labyrinthitis.
Injection Rhinoplasty with Hyaluronic Acid and Calcium Hydroxyapatite: A Retrospective Survey Investigating Outcome and Complication Rates

Abstract Injection rhinoplasty offers an attractive, reversible alternative to surgery. Here we assessed outcome, longevity of benefits, adverse effects, and patient assessment of injection rhinoplasty, using degradable synthetic fillers. Forty-six patients who underwent injection rhinoplasty using degradable fillers over the past 3 years were assessed (calcium hydroxyapatite: 26 patients, hyaluronic acid: 20 patients). Comparison of pre- and postoperative images indicated realistically achievable treatment results. Patient satisfaction was assessed using a 5-point questionnaire at 3 weeks and 9 months posttreatment. Forty-six patients (88 areas) were treated. At 3 weeks posttreatment, 85% of patients were satisfied with treatment results. At 9 months or later posttreatment, 87% of patients were very/completely satisfied with treatment results, regardless of filler used. Treatment longevity varied between 6 and 30 months (mean: 13.5 months). Positive evaluation was mainly due to accurate prediction of achievable results to meet patient expectations. There were one moderate and two severe complications, all following calcium hydroxyapatite treatment. Two resolved completely following treatment and one patient was lost to follow-up. This resulted in subsequent exclusive use of hyaluronic acid filler. Injectable biodegradable fillers are effective for correction of minor nasal deformities or irregularities. Attention must be given to injection technique and adverse effect management.
Liver irradiation causes distal bystander effects in the rat brain and affects animal behaviour

Radiation therapy can not only produce effects on targeted organs, but can also influence shielded bystander organs, such as the brain in targeted liver irradiation. The brain is sensitive to radiation exposure, and irradiation causes significant neuro-cognitive deficits, including deficits in attention, concentration, memory, and executive and visuospatial functions. The mechanisms of their occurrence are not understood, although they may be related to the bystander effects. We analyzed the induction, mechanisms, and behavioural repercussions of bystander effects in the brain upon liver irradiation in a well-established rat model. Here, we show for the first time that bystander effects occur in the prefrontal cortex and hippocampus regions upon liver irradiation, where they manifest as altered gene expression and somewhat increased levels of γH2AX. We also report that bystander effects in the brain are associated with neuroanatomical and behavioural changes, and are more pronounced in females than in males.
Aberrant cardiolipin metabolism in the yeast taz1 mutant: a model for Barth syndrome

In eukaryotic cells, the acyl species of the phospholipid cardiolipin (CL) are more highly unsaturated than those of the other membrane phospholipids. Defective acylation of CL with unsaturated fatty acids and decreased total CL are associated with Barth syndrome, an X‐linked cardio‐ and skeletal myopathy attributed to a defect in the gene G4.5 (also known as tafazzin). We constructed a yeast mutant (taz1) containing a null mutation in the homologue of the human G4.5 gene. The yeast taz1Δ mutant was temperature sensitive for growth in ethanol as sole carbon source, but grew normally on glucose or glycerol plus ethanol. Total CL content was reduced in the taz1Δ mutant, and monolyso‐CL accumulated. The predominant CL acyl species found in wild‐type cells, C18:1 and C16:1, were markedly reduced in the mutant, whereas CL molecules containing saturated fatty acids were present. Interestingly, CL synthesis increased in the mutant, whereas expression of the CL structural genes CRD1 and PGS1 did not, suggesting that de novo biosynthetic enzyme activities are regulated by CL acylation. These results indicate that the taz1Δ mutant is an excellent genetic tool for the study of CL remodelling and may serve as a model system for the study of Barth syndrome.
Exploring Health Information Technology Innovativeness and its Antecedents in Canadian Hospitals

Summary Objectives: The primary aim of this study was to assess the antecedents of health information technology (HIT) innovativeness in public hospitals. To do so, we built upon our own previous work to relate the level of HIT innovativeness to organizational capacity characteristics. Methods: We conducted a survey of chief information officers (CIOs) in public hospitals in the two largest Canadian provinces to identify the level of HIT innovativeness in these settings and test nine research hypotheses derived from the proposed research model. Results: A total of 106 completed questionnaires were received, which represents a response rate of 52%. Our findings indicate strong support for the research model. Seven out of nine hypotheses were supported indicating a significant relationship between HIT innovativeness and structural, financial, leadership, and knowledge sharing capacity characteristics. Results also reveal a moderate level of HIT innovativeness in the surveyed hospitals, with more emphasis on administrative systems and their integration than on clinical systems and emerging technologies. Conclusions: This study demonstrates that organizational characteristics are related to HIT innovativeness; this relationship holds irrespective of the public or private nature of hospitals.
Three Dimensional Pulse Coupled Neural Network Based on Hybrid Optimization Algorithm for Oil Pollution Image Segmentation

This paper proposes a three dimensional pulse coupled neural network (3DPCNN) image segmentation method based on a hybrid seagull optimization algorithm (HSOA) to solve the oil pollution image. The image of oil pollution is taken by the unmanned aerial vehicle (UAV) in the oil field area. The UAV is good at shooting the ground area, but its ability to identify the oil pollution area is poor. In order to solve this problem, a 3DPCNN-HSOA algorithm is proposed to segment the oil pollution image, and the oil pollution area is segmented to identify the dirty oil area and improve the inspection of environmental pollution. The 3DPCNN image segmentation method has simple structure and good segmentation effect, but it has many parameters and poor segmentation effect for complex oil images. Therefore, we apply HSOA algorithm to optimize the parameters of 3DPCNN algorithm, so as to improve the segmentation accuracy and solve the segmentation of oil pollution images. The experimental results show that the 3DPCNN-HSOA model can separate the oil pollution area from the complex background.

Modern people possess the capacity to divide themselves into separate modules of thought and action, and deploy them flexibly (Gellner, 1994). The employment relationship, which divides the tasks and skills required for the job role from the rest of the person, has always relied upon this modular capacity (Kallinikos, 2003). The growing practice of ‘informatizing’ work by representing tasks as software-based instructions entails the modular design and management of work, because software itself has a modular form. We investigate the implications of the modular design of work in the empirical context of a ‘shared service centre’, where professional service work was informatized. We make three contributions. First, transforming work into software-based processes makes organizations configurable, because work can be treated as an arrangement of modules which can be adapted, replicated or deleted, irrespective of the professional expertise of employees. Second, this way of organizing demands that employees attempt to deploy enhanced modular capabilities: they must be able to execute any given set of processes, and adapt instantaneously to changing circumstances, by setting aside modules that are no longer required and engaging competently with new ones, all in a strictly unemotional and time-efficient fashion. Third, we argue that under circumstances of financial pressure, the continuing availability of sophisticated software which can be used to informatize complex work, and the existence of established organizational templates which accommodate standardized service work, the modular design and management of other types of professional services may become increasingly common.
The Legionella pneumophila LidA protein: a translocated substrate of the Dot/Icm system associated with maintenance of bacterial integrity

Legionella pneumophila establishes a replication vacuole within phagocytes that requires the bacterial Dot/Icm apparatus for its formation. This apparatus is predicted to translocate effectors into host cells. We hypothesized that some translocated proteins also function to maintain the integrity of the Dot/Icm translocator. Mutations that destroy this function are predicted to result in a Dot/Icm complex that poisons the bacterium, resulting in reduced viability. To identify such mutants, strains were isolated (called lid – ) that showed reduced viability on bacteriological medium in the presence of an intact Dot/Icm apparatus, but which had high viability in the absence of the translocator. Several such mutants were analysed in detail to identify candidate strains that may have lost the ability to synthesize a translocated substrate of Dot/Icm. Two such strains had mutations in the lidA gene. The LidA protein exhibits properties expected for a translocated substrate of Dot/Icm that is important for maintenance of bacterial cell integrity: it associates with the phagosomal surface, promotes replication vacuole formation, and is important for both efficient intracellular growth and high viability on bacteriological media after introduction of a plasmid that allows high level expression of the dotA gene.
Genetic variation in threshold reaction norms for alternative reproductive tactics in male Atlantic salmon, Salmo salar

Alternative reproductive tactics may be a product of adaptive phenotypic plasticity, such that discontinuous variation in life history depends on both the genotype and the environment. Phenotypes that fall below a genetically determined threshold adopt one tactic, while those exceeding the threshold adopt the alternative tactic. We report evidence of genetic variability in maturation thresholds for male Atlantic salmon (Salmo salar) that mature either as large (more than 1 kg) anadromous males or as small (10–150 g) parr. Using a common-garden experimental protocol, we find that the growth rate at which the sneaker parr phenotype is expressed differs among pure- and mixed-population crosses. Maturation thresholds of hybrids were intermediate to those of pure crosses, consistent with the hypothesis that the life-history switch points are heritable. Our work provides evidence, for a vertebrate, that thresholds for alternative reproductive tactics differ genetically among populations and can be modelled as discontinuous reaction norms for age and size at maturity.
Deletion of the copper transporter CaCCC2 reveals two distinct pathways

 for iron acquisition in Candida albicans

Efficient iron acquisition is an essential requirement for growth of pathogenic organisms in the iron‐poor host environment. In Saccharomyces cerevisiae, high‐affinity iron import depends on the multicopper ferroxidase ScFet3. ScFet3 biogenesis in the trans‐Golgi compartment requires a copper‐transporting P‐type ATPase, ScCcc2. Here, we describe the isolation by functional complementation of a Ccc2 homologue from the pathogenic yeast Candida albicans. CaCcc2 is functionally distinct from a previously described C. albicans copper‐transporting P‐type ATPase, CaCrp1, which appears to be specifically involved in copper detoxification. Regulation of CaCCC2 and the phenotype of the homozygous CaCCC2 deletion indicate that it is required for high‐affinity iron import, making it the bona fide CCC2 homologue of C. albicans. Remarkably, in a mouse model of systemic infection, the Caccc2Δ strain displayed robust proliferation and no significant reduction in pathogenicity, suggesting the existence of alternative mechanisms of iron uptake from host tissues. We identify haemin and haemoglobin as potential iron sources that can be used by C. albicans in a CaCcc2‐independent manner.
Molecular characterization of a t(2;6) balanced translocation that is associated with a complex phenotype and leads to truncation of the TCBA1 gene

The molecular characterization of balanced chromosomal rearrangements has often been a powerful tool for the positional identification of genes associated with specific diseases. In some instances, these rearrangements may be associated with a variety of different phenotypes, and thus establishing a genotype–phenotype correlation may be a complex process. However, molecular characterization of the rearrangement remains a useful tool for diagnoses or prognoses, or for identifying new genes and establishing a gene‐to‐function relationship. In this work we describe the characterization of a de novo balanced translocation t(2;6)(q24.3;q22.31) found in a patient with a complex phenotype. The major clinical finding was a severe neurological involvement. Thanks to the molecular characterization of this translocation we found that the rearrangement led to the truncation of the TCBA1 gene on chromosome 6q. We found that the gene is transcribed in different splice variants and is highly specific for the central nervous system. TCBA1 does not show any similarity with other known genes, and no information is available about its function. However, the gene appears to be well conserved among species, and we were able to infer the sequence of a putative mouse homolog of TCBA1. This allowed us to perform a more detailed expression study in mice, thus confirming its specificity for the nervous system. This finding is of particular interest because it suggests that TCBA1 may be correlated with the neurological phenotype of our patient, and possibly mutated in genetic diseases with a neurological phenotype.
