Chest Wall Abscess: A Rare Complication of Influenza

Every year, the influenza virus affects thousands of children, most of whom have mild disease requiring only symptomatic treatment. A small percentage of those children go on to develop more severe complications, including pneumonia, empyema, myositis, and sepsis. We present the case of a previously healthy 6-year-old female who developed an extra-pulmonary, extra-muscular right anterior chest wall abscess following infection with influenza. To our knowledge, this sort of abscess has never been described in a pediatric patient in the literature.

preliminary Findings in the development of a theoretical Framework for Investigating Ict Integration in teacher Education

The following report is the result of a preliminary investigation in the development of a theoretical framework for investigating ICT integration, particularly in TESL (Teaching of English as a Second Language) teacher training. The study is primarily an empirical effort to develop a theoretical framework for investigating ICT integration in TESL teacher training. In identifying the predictive variables for the framework, the researchers conducted an intensive review of the literature which included a review of various models used in studies on ICT integration. The contributing variables identified in the present study were age, gender, experience, ICT proficiency, attitude, access to ICT infrastructure, support services, and exposure to ICT professional development programmes. In developing the framework, the study sought to determine the extent to which the observed variability in ICT integration could be predicted by these factors. The sample comprised 266 respondents working at the faculty or English Language Unit in various teacher training institutions across the country. The study predominantly employed quantitative methods of data collection. Interview data was used to corroborate information derived from the survey data.
Assessing Regional Habitat Changes for the Persian fallow deer (Dama dama mesopotamicus) using Maximum Entropy modeling approach in Khouzestan province, Iran

This study was conducted in Dez and Karkheh regions in southwestern Iran to model habitat suitability of the Persian fallow deer Dama dama mesopotamicus and assessing trend of habitat changes since 1989. A total of 22 confirmed presence records of the species were collected from 1988 to 2003. MaxEnt approach was used to develop habitat suitability model with regards to nine environmental variables, including density of farmlands, forests, and disturbed forests, density of livestock, vegetation, residential areas and distance to the forest edge, residential areas, protected areas and frequency of surface water bodies. After validation of the model for all parameters used for 1989, relative developed map was extrapolated to the habitat conditions in 2007. Comparing the habitat suitability maps developed for 1989 and 2007 reveals that area of suitable habitats for the Persian fallow deer has declined by 30% within 18 years. A total of 1000 ha of forests (within suitable habitats for the species) has been degraded. About 100 ha of these habitats were converted to farmlands and less than 0.5 ha was altered to the residential areas. In addition, area of about 1000 ha has lost the suitability without any land use changes. Currently, reintroduction of the Persian fallow deer to the area is under consideration by Department of Environment of Iran. Therefore, results of this study are recommended for choosing reintroduction sites based on the predicted suitable maps to enhance the probability of survival for reintroduced individuals.
Running Head: EXPLORING TASK SET RECONFIGURATION IN SYNESTHESIA Cost of mental set reconfiguration in a digit-photism synesthete

The task switch paradigm has helped psychologists gain insight into the processes involved in changing from one activity to a new one. In this study we present experiments in which we investigate the reconfiguration process elicited by the task switching paradigm in synesthesia. In Group 1, N. , a digit-colour synesthete, alternated between an odd-even task and a colour task (to indicate the photism elicited by each digit). In both tasks, the target stimuli were numbers between 1 and 9 written in white. One of the control groups ran the same tasks but this time with coloured numbers. The results of these studies showed: a significant task switch cost with an abrupt offset; a cost reduction in long RSI; and a significant interaction between the switch cost and the Stroop effect. Taken together, our results indicate that the conceptual mental set reconfiguration shown by the participant with synesthesia is similar to the perceptual mental set reconfiguration of the control group.
The development and application of a length-based method to estimate the spawning potential ratio in data-poor fish stocks

Although they support many millions of people, the vast majority of the world’s fisheries are small-scale and data-poor, and without the resources or data systems needed for comprehensive stock assessments. There is strong evidence that unmanaged fisheries are a recipe for disaster, with over-exploitation of the stock almost inevitable. Additionally, it is increasingly recognised that the spatial scale of the stocks of many marine species is much smaller than previously thought, which adds another layer of cost to the stock assessment process, as the cost of collecting and analysing such fine-scale data is prohibitive. The overall aim of this thesis was to develop and test novel methods of stock assessment for data-poor and small-scale fisheries, based on the basic biological characteristics of the exploited species. Knowledge of the basic biological parameters of fish stocks, such as the natural mortality rate (M), the growth parameters (commonly described by the von Bertalanffy equation, L¥ and k), and the length at maturity (Lm), is important for many stock assessment methodologies. However, collecting such information is costly, and usually requires sophisticated ageing studies. I conducted a meta-analysis of over 120 marine species, from a range of taxa including teleosts, chondrichthyans, mammals and invertebrates, and examined the variation and patterns in the life-history ratios, and the relationships between size and spawning potential (Chapter 2). These patterns were examined by standardising the age and size of each species so that the relationship between size and spawning-per-recruit for a large range of diverse species could be compared on the same scale. This meta-analysis demonstrated that species that are often considered to be quite different, essentially have the same life-history strategy when viewed on the same relative scale. For example, tuna can be considered as ‘larger, slower’, anchovies, while prawns are ‘smaller, faster’ versions of fish. Additionally, and somewhat surprisingly, a number of teleosts with low Mk values of _ 0:5 appear to have life-histories similar to marine mammals, and quite different from those expected of fish. The results of this study suggest that there is potential to establish a theoretical framework for ‘borrowing’ knowledge from well-studied species to apply to unstudied species and populations as an initial starting point for management. The ratios of these parameters _ Mk and Lm L¥ _ are less variable between individual stocks o_f the same species than the individual parameters, and certain values of these ratios Mk= 1 : 5 and Lm L¥ = 0:66 _ , known as the Beverton and Holt Life History Invariants (BH– LHI) have been used commonly to provide preliminary estimates of unknown parameters. However, many species have life-history ratios that vary considerably from the BH–LHI, and in this study I demonstrate the link between variation in the ratios _ Mk and Lm L¥ _ and the life-history strategy of a species. For example, species with low Mk
Morphological and physiological responses of two common bean cultivars to drought stress

Drought stress is the major problem in arid and semi-arid regions of the world. Investigating the response of different cultivars of crop plants to drought stress can help to select the tolerant cultivars ones for agriculture in arid lands. In this study, a greenhouse experiment was conducted as a factorial experiment based on completely randomized design with two common bean cultivars (Phaseolus vulgaris L.) including Derakhshan and Goli, and four moisture levels of 25, 50, 75 and 100% field capacity. When the true leaves emerged (10 days after planting), the seedlings were exposed to the different levels of drought stress until the end of the flowering stage. Based on the morphological (stem length, leaf and root area, dry weight of shoot and root, and the root/shoot ratio), physiological (leaf relative water content, membrane stability index, photosystem II photochemical efficiency, stomatal resistance, chlorophyll index, and water use efficiency), and biochemical (proline content, soluble protein content, and the activity of antioxidant enzymes including superoxide dismutase, polyphenol oxidase, and peroxidase) characteristics, both cultivars showed a relatively good tolerance to the low and intermediate drought stress, while both were sensitive to the highest level of drought condition (25% field capacity). The main characteristics which indicated the tolerance of common bean cultivars to drought stress was an increase in the root/shoot ratio, stomatal resistance, water use efficiency, proline content, and antioxidant enzyme activity. Regarding these characteristics, the responses of Derakhshan cultivar more associated with drought tolerance, compared with Goli cultivar.
New microchondrometer to measure hectoliter weight in small samples of wheat

The hectoliter weight or test weight is an important wheat quality parameter for international trade and is traditionally evaluated on devices with a volume of 250, 500, 1000 or 1100 ml. At the experimental level, especially in crop improvement and in greenhouse studies, the amount of grain is often insufficient to determine hectoliter weight. The present work aimed to evaluate the feasibility of using a new 15.30 ml microchondrometer to evaluate hectoliter weight. The testing process was carried out in two steps: (i) To evaluate the need to compress wheat grains inside the microchondrometer cylinder with weights of 0, 4.4, 8.8 and 13.2 kg, and (ii) To verify the effect of different piston weights (4.0, 9.52, 17.56, 28.44 and 31.69 g). A comparison of four compression treatments and five piston weights between 250 ml and 15.30 ml chondrometers were performed by Spearman's correlation coefficient and t-test. The results showed a highly significant correlation coefficient (r=0.99) between the two apparatus and lack of significance for compression and piston weights. The 15.30 ml microchondrometer, in addition to allowing better characterization in small grain samples, will also help to discard unwanted genotypes early in the selection process. Key words: Plant breeding, grain density, genotype screening.
Predicting the Onset of Glaucoma

Objective: To evaluate the predictive ability of baseline confocal scanning laser ophthalmoscopy (CSLO) Glaucoma Probability Score (GPS) for the development of primary open-angle glaucoma (POAG) and to compare it with the Moorfields regression analysis (MRA) classification, other topographic optic disc parameters, and stereophotograph-based cup-to-disc ratio. Design: Longitudinal, randomized clinical trial. Participants: We included 857 eyes of 438 participants in the CSLO Ancillary Study to the Ocular Hypertension Treatment Study (OHTS) with good quality baseline CSLO images. Methods: The ability of baseline GPS, MRA, and optic disc parameters to predict the development of POAG was evaluated in univariate and multivariable proportional hazard ratio analyses. Likelihood ratios and positive and negative predictive values were compared. Main Outcome Measures: The POAG end point as determined by repeatable changes in the visual field or optic disc. Results: Sixty-four eyes of 50 CSLO Ancillary Study participants developed POAG. Median time to reach a POAG end point was 72.3 months. The 93 eyes of 388 participants not reaching endpoint were followed for a median of 124.9 months. Baseline GPS identified many more eyes as outside normal limits than the MRA. In multivariable analyses, all regional and global baseline GPS indices were significantly associated with the development of POAG; hazard ratios (95% confidence interval) ranged from 2.92 to 3.74 for an outside normal limits result. The MRA indices were also significantly associated with the development of POAG in multivariable analyses. In addition, the predictive ability of baseline GPS, MRA and stereometric parameters were similar to the predictive ability of models using photograph-based horizontal cup-to-disc ratio. Conclusions: These results suggest that baseline GPS, MRA, and stereoparameters alone or when combined with baseline clinical and demographic factors can be used to predict the development of POAG end points in OHTS participants and are as effective as stereophotographs for estimating the risk of developing POAG in ocular hypertensive subjects.

Interactive effect with AM fungi and Azotobacter inoculated seed on germination, plant growth and yield in cotton (Gossypium hirsutum)

Studies were carried out to evaluate the response of cotton to inoculation with IAA producing diazotroph, Azotobacter chroococcum. The effect of A. chroococcum inoculation on cotton seed germination and seedling development was observed to be beneficial for both parameters. A field experiment was also conducted to ascertain the effects of dual inoculation of A. chroococcum (CBD-15, M-4, BA-l and OA-4) as seed application and AM fungi as soil inoculant on cotton (Gossypium hirsutum L.) var. Pusa 8-6. There was significant improvement in plant height, number of flowers and bolls formed, boll weight and seed cotton yield in most of the treatments as compared to uninoculated control. Synergistic effects of dual inoculation of all the A. chroococcum strains with AM fungi were observed for boll weight and seed cotton yield. A significant positive correlation between population of Azotobacter sp. in rhizosphere of cotton with weight of bolls and seed cotton yield was observed.
Cartographic Vandalism in the Era of Location-Based Games - The Case of OpenStreetMap and Pokémon GO

User-generated map data is increasingly used by the technology industry for background mapping, navigation and beyond. An example is the integration of OpenStreetMap (OSM) data in widely-used smartphone and web applications, such as Pokémon GO (PGO), a popular augmented reality smartphone game. As a result of OSM’s increased popularity, the worldwide audience that uses OSM through external applications is directly exposed to malicious edits which represent cartographic vandalism. Multiple reports of obscene and anti-semitic vandalism in OSM have surfaced in popular media over the years. These negative news related to cartographic vandalism undermine the credibility of collaboratively generated maps. Similarly, commercial map providers (e.g., Google Maps and Waze) are also prone to carto-vandalism through their crowdsourcing mechanism that they may use to keep their map products up-to-date. Using PGO as an example, this research analyzes harmful edits in OSM that originate from PGO players. More specifically, this paper analyzes the spatial, temporal and semantic characteristics of PGO carto-vandalism and discusses how the mapping community handles it. Our findings indicate that most harmful edits are quickly discovered and that the community becomes faster at detecting and fixing these harmful edits over time. Gaming related carto-vandalism in OSM was found to be a short-term, sporadic activity by individuals, whereas the task of fixing vandalism is persistently pursued by a dedicated user group within the OSM community. The characteristics of carto-vandalism identified in this research can be used to improve vandalism detection systems in the future.
On the interaction of a-crystallin with membranes

The interaction of human and bovine α-crystallins with bovine lens membranes was evaluated using binding curves and Scatchard plots constructed from scans of SDS-PAGE gels and/or from the association of [14C]-leu α-crystallin with the membranes.No differences were observed for total bovine, normal human 19 and 88 year old and cataractous α-crystallins. In each case, interaction takes place through two distinct processes, a) a high affinity (Kd = 1 × 10-8M) binding with low capacity (25 mg α-crystallin/g membrane protein) and b) partitioning (Kp = 0.25 1/g membrane protein). Loss of the high-affinity binding component was observed for bovine nuclear α-crystallin.Contrary to previous reports, it is concluded that cataract formation does not affect the ability of human α-crystallins to interact with bovine lens membranes. Reanalysis of previously published data supports this conclusion.
Globalization and International Migration: Implicat ions for Irregular Migration in Eastern Zone of Tigray Regional State

The issue of irregular migration these days is beco ming a topical and pressing issue with both short and long term multif aceted consequences. However, studies so far in the study area get short of integrated approach in dealing the issue and its actors and factors dyn amism along line with waves of globalization. This research project is th erefore, intended to investigate the dynamics of actors and contextual f actors interplay in a way that can gave a full picture of irregular migra tion. The study employed qualitative research approach with purposi ve and snow ball sample selection technique. The study revealed that , with the adverse expansion of globalization and borderless mobility of goods, services, finance and information, the actors and factors int erplay in facilitating irregular migration is drastically changing. As suc h the application of static and one-fits all policy approach to mitigate and reduce migration flow is proved to be less effective in the study ar ea. Moreover, poverty, livelihood survival difficulty, ecological factors of the study area, Social network of pioneer migrant back and forth, systemat ization of traffickers and smugglers, the issue of psycho-social construct ion are most pressing issues that all combined together exacerbating and shaping the nature and magnitude of irregular migration in the study area. To this end, Sharpening and widening anti human trafficking laws and policies, designing feasible poverty and unemployment reducin g strategies accompanied by modest labor wage with framed short and long term effects are the core insights that can have signifi cant return in reversing irregular migration in the study area.
The Comparative Morphology of the Pectoral Free Rays in Scorpaenoid Fishes (perciformes: Scorpaenoidea))

The pectoral fins of many benthic taxa have evolved many unique features used to interact with the substrate. In one such group, the searobins (Triglidae: Scorpaenoidea), three of the pectoral fin rays have become separated from the fin as a whole, allowing them to operate as a separate appendage from the fin as a whole. The anatomical structure of these "free rays" was investigated and several previously unreported muscle and bone variations were found. This method was extended to include members of four other scorpaenoid families which possess free rays, which revealed important differences in the muscle, bone, and nervous structure of this trait. Geometric morphometric analysis of major free ray components displays family specific patterns in the attachment of muscles and shape of bone processes. The anatomical diversity of this trait suggests that it has evolved multiple times and has taken on unique specialized roles in each taxon.
STRATEGY REORGANIZE EUROPEAN AIR TRAFFIC

Air transport forms complex networks that can be measured in order to understand its structural characteristics and functional properties. Recent models for network growth (i.e., preferential attachment, etc.) remain stochastic and do not seek to understand other network-specific mechanisms that may account for their development in a more microscopic way. Air traffic is made up of many constituent airlines that are either privately or publicly owned and that operate their own networks. They follow more or less similar business policies each. The way these airline networks organize among themselves into distinct traffic distributions reveals complex interaction among them, which in turn can be aggregated into larger (macro-) traffic distributions. Our approach allows for a more deterministic methodology that will assess the impact of airline strategies on the distinct distributions for air traffic, particularly inside Europe. One key question this paper is seeking to answer is whether there are distinct patterns of preferential attachment for given classes of airline networks to distinct types of European airports. Conclusions about the advancing degree of concentration in this industry and the airline operators that accelerate this process can be drawn. _____________________________________________________________________________ Dr. Hans Huber is a Senior Research Fellow within the Management of Networked Industries department of Ecole Polytechnique Fédérale de Lausanne, Switzerland.
