Erosion of dust aggregates

Aims: The aim of this work is to gain a deeper insight into how much different aggregate types are affected by erosion. Especially, it is important to study the influence of the velocity of the impacting projectiles. We also want to provide models for dust growth in protoplanetary disks with simple recipes to account for erosion effects. Methods: To study the erosion of dust aggregates we employed a molecular dynamics approach that features a detailed micro-physical model of the interaction of spherical grains. For the first time, the model has been extended by introducing a new visco-elastic damping force, which requires a proper calibration. Afterwards, different sample generation methods were used to cover a wide range of aggregate types. Results: The visco-elastic damping force introduced in this work turns out to be crucial to reproduce results obtained from laboratory experiments. After proper calibration, we find that erosion occurs for impact velocities of 5 ms$^{-1}$ and above. Though fractal aggregates as formed during the first growth phase are most susceptible to erosion, we observe erosion of aggregates with rather compact surfaces as well. Conclusions: We find that bombarding a larger target aggregate with small projectiles results in erosion for impact velocities as low as a few ms$^{-1}$. More compact aggregates suffer less from erosion. With increasing projectile size the transition from accretion to erosion is shifted to higher velocities. This allows larger bodies to grow through high velocity collisions with smaller aggregates.
Prevalence of Helicobacter Pylori Infection in Asymptomatic Children in Birjand, Eastern Iran

Background: Helicobacter pylori is the cause of serious diseases including gastric cancer and gastric mucosa–associated lymphoid tissue lymphoma.50% of world population is infected by this microorganism and it -based on epidemiologic studies - is mainly acquired during childhood . there is not enough evidence about prevalence of this infection in children and its risk factors so encourage us to study on it.Method : we tested 282 apparently healthy 9-12 year old students in a population based cross sectional study for Helicobacter pylori colonization using H pylori Antigen EIA Test Kit (ACON company). a short socio demographic questionnaire was used to assess risk factors.Findings: the overall prevalence of H pylori colonization in 282 students is 13.1%. we found statistically significant relationship between H pylori colonization and sex, duration of breast feeding, and family crowding but there is not significant relationship with age , family history of dyspepsia , number of days in week consuming yogurt and economically stratified living region in present study.Conclusion: Helicobacter Pylori is a big concern even in young asymptomatic children and it needs to be further studied about its potential risk factors and how to manage them for the goal of prevention.
Characterizing and reducing crosstalk in printed anaglyph stereoscopic 3D images

Abstract. The anaglyph three-dimensional (3D) method is a widely used technique for presenting stereoscopic 3D images. Its primary advantages are that it will work on any full-color display and only requires that the user view the anaglyph image using a pair of anaglyph 3D glasses with usually one lens tinted red and the other lens tinted cyan. A common image quality problem of anaglyph 3D images is high levels of crosstalk–the incomplete isolation of the left and right image channels such that each eye sees a “ghost” of the opposite perspective view. In printed anaglyph images, the crosstalk levels are often very high–much higher than when anaglyph images are presented on emissive displays. The sources of crosstalk in printed anaglyph images are described and a simulation model is developed that allows the amount of printed anaglyph crosstalk to be estimated based on the spectral characteristics of the light source, paper, ink set, and anaglyph glasses. The model is validated using a visual crosstalk ranking test, which indicates good agreement. The model is then used to consider scenarios for the reduction of crosstalk in printed anaglyph systems and finds a number of options that are likely to reduce crosstalk considerably.
On an epidemic in a stratified population

Most epidemic models previously studied have assumed a homogeneously mixing population. Instead of making this assumption, a population divided into classes is considered; and it is assumed that the degree of mixing between classes is less than that within classes. The stochastic model in this form is intractable and approximations are made, yielding results in reasonable agreement with simulation trials.
COMPARISON OF THERAPUTICAL EFFICACY OF ALBENDAZOL, LEVOZAN AND IVERMECTINE IN TREATMENT OF BUFFALOES NATURALLY INFECTED WITH GASTRO-INTESTINAL WORMS IN MOSUL, IRAQ

The object of this study is to compare the effi cacy of a single dose of albendazol (Group 1) (10 mg/kg. BW oral suspension) and a single dose 2.5 ml/10 kg. BW. of levozan (Group 2) oral suspension (a mixture of levamisole and oxyclozanide) and ivermectine (Group 3) 0.2 mg/kg. BW. (S.C injection) for one time in the treatment of buffaloes naturally infected with gastro-intestinal worms. Thirty buffaloes of local breed 6 months to more than 4 years old were used in this study, the animals were divided into three equal groups (10 buffaloes for each). Based on the number of days taken for parasitological cure, and mean reduction EPG. Total erythrocytes count (RBCs), hemoglobin concentration (HB), packed cell volume (PCV), total platelets count (Plt) and erythrocytes sedimentation rate (ESR), were also encountered pre-and post treatment. Results indicated reduction in EPG to zero on the 7 th day post treatment (Group 1) which also showed a signifi cant increase in RBCs, HB, PCV and Plt and a signifi cant decrease in ESR on the 14 th day post treatment,while there was gradual reduction of EPG without complete elimination of total eggs count on day 21 of treatment with Groups (2) and (3). Levosan was found highly effective in the treatment of buffaloes naturally infested with gastro-intestinal worms.
The Nuts and Bolts of Qualitative Research

Although qualitative research has gained more popularity than before in the field of language education, we need to continue sharing the terms relating to qualitative research and discussing the interpretations about them. In this paper, I provide a brief description of fundamental issues surrounding qualitative research by introducing germane concepts (e.g., approach, paradigm and research methods) and by explaining relevant criteria to evaluate the research (e.g., credibility, transferability, dependability and confirmability). To achieve this, I use a qualitative-oriented study that I conducted (Hiratsuka, 2014) as an illustrate example. I conclude this paper with recommendations for further qualitative studies.

An X-ray survey of the central molecular zone: Variability of the Fe Kα emission line

There is now abundant evidence that the luminosity of the Galactic super-massive black hole (SMBH) has not always been as low as it is nowadays. The observation of varying non-thermal diffuse X-ray emission in molecular complexes in the central 300 pc has been interpreted as delayed reflection of a past illumination by bright outbursts of the SMBH. The observation of different variability timescales of the reflected emission in the Sgr A molecular complex can be well explained if the X-ray emission of at least two distinct and relatively short events (i.e. about 10 years or less) is currently propagating through the region. The number of such events or the presence of a long-duration illumination are open questions. Variability of the reflected emission all over of the central 300 pc, in particular in the 6.4 keV Fe Ka line, can bring strong constraints. To do so we performed a deep scan of the inner 300 pc with XMM-Newton in 2012. Together with all the archive data taken over the course of the mission, and in particular a similar albeit more shallow scan performed in 2000-2001, this allows for a detailed study of variability of the 6.4 keV line emission in the region, which we present here. We show that the overall 6.4 keV emission does not strongly vary on average, but variations are very pronounced on smaller scales. In particular, most regions showing bright reflection emission in 2000-2001 significantly decrease by 2012. We discuss those regions and present newly illuminated features. The absence of bright steady emission argues against the presence of an echo from an event of multi-centennial duration and most, if not all, of the emission can likely be explained by a limited number of relatively short (i.e. up to 10 years) events.
Temporal changes in the polychaete infaunal community surrounding a Hawaiian mariculture operation

Benthic monitoring efforts in the vicinity of a Pacific threadfin Polydactylis sexfilis mar- iculture venture have allowed us to examine eutrophic effects on the infaunal community. Polychaete infaunal communities from 2 sites near the point source were compared to 2 control stations beyond the range of fish feed and wastes. Regression analysis indicated significant decreases in Shannon- Weiner diversity over time and near the effluent source. Non-metric multidimensional scaling (nMDS) showed a progression of species succession and turnover at impacted sites but relatively unchanging polychaete communities at control sites. An analysis of similarity (ANOSIM) indicated significant differences between community structures at impacted and control sites but less obvious differences over time. An abundant and regionally widespread polychaete Pionosyllis heterocirrata had disappeared from impacted sites. Increasing abundances of 2 opportunistic polychaetes, Capitella capitata (complex) and Ophryotrocha adherens, resulted in decreasing Shannon-Weiner diversity values (H ') at impacted stations. Expanding populations of C. capitata and O. adherens seem to be preceded by high densities of Myriochele oculata. These 3 species may represent an order of succession due to attrition by anoxia in Hawaiian waters. Deviation of the infaunal polychaete community at impacted sites resulting from the appearance of polychaete pollution indicators, low species richness resulting from the disappearance of ambient polychaete species and depressed com- munity abundance reflect the effects of fish mariculture on the benthic community. Such effects may be diluted by the open-ocean location on the south shore of O'ahu, Hawai'i.
Variability of shear and microtensile bond strength tests to enamel and dentin

Purpose: This study aimed to provide guidelines about the coefficient of variation (CV) of shear (SBS) and microtensile (μTBS) bond strength to enamel and dentin. Methods: A search of the English language peer-reviewed literature was conducted using the PubMed database from 2000 to 2009. Only bond strength studies (SBS and μTBS) that have tested both enamel and dentin substrates were selected. The following information was gathered from the 103 papers selected: groups mean and standard deviation (SD), repetition number, and type of statistical analysis. The CV of each study was calculated by using its mean and SD values, the normality of shear and microtensile CV was analyzed using Shapiro-Wilk test, and a CV classification was established for each variable. Results: According to the CV classification proposed, values below 10.3% and 11.3% could be considered low for shear bond strength to enamel and dentin, respectively; and values below 15.4% to enamel and 16.4% to dentin could be considered low for the microtensile test. Values higher than 46.8% and 62.1% (shear bond strength to enamel and dentin) and 45.9% and 45.5% (microtensile bond strength to enamel and dentin) showed a very high variability. Conclusion: Such classification can be useful for future experiments on adhesive materials to estimate statistical power and data precision.
F.J. and Mathews, K. (2016) Impact of information transfer on farmers' uptake of innovative crop technologies: a structural equation model applied to survey

This study analyses the impact of the transfer of technological information (among other a priori identified factors) on the uptake of innovative crop technologies using structural equation modelling of data from a representative survey of Scottish crop farmers. The model explains 83% of the variance in current technological uptake behaviour and 63% of the variance in intentions to uptake new technologies. Results show economic characteristics (profit orientation, agricultural income, technological investment behaviour and farm labour) to have the strongest effect on both uptake and intentions to uptake novel technologies. Education, access to technological information and perceived usefulness of sources of information transfer are also main influences on behaviour and intentions. Technological uptake behaviour is a strong determinant of intentions to uptake more technologies in the future. The results confirm established evidence from the & L. Toma luiza.toma@sruc.ac. uk A.

The Impact of Personality: Extrovert vs. Introvert on the Ability in Syntax in Essay Writing

The main purpose of this study was to find out if there would be any significant difference in scores for syntax in essay writing between extrovert and introvert EFL learners. The quantitative data were collected by applying writing rubrics from Brown (2007). The participants of this study were 40 English learners (20 extroverts and 20 introverts) at Universitas Negeri Medan, Indonesia. The data were analyzed by using Statistical Package for the Social Sciences (SPSS) version 2.0. The findings of this study indicated that there was a significant difference in the scores for syntax between extrovert and introvert learners. In this study, introvert EFL learners did better than extrovert EFL learners in constructing sentences (syntax). Thus, both groups still have an equal chance to improve their ability in a learning foreign language particularly in writing skills but extrovert EFL learners must pay more attention to using good syntax because they tend to be careless and less correct in constructing their phrases when doing a writing task.
Positive solutions for a class of nonlocal impulsive BVPs via fixed point index

We study the existence of positive solutions for perturbed impulsive integral equations. Our setting is quite general and covers a wide class of impulsive boundary value problems. We also study other cases that can be treated in a similar manner. The main ingredient in our theory is the classical fixed point index theory for compact maps.
Government through time: participation and poverty reduction in Tanzania

This paper examines the relation between government and poverty in Tanzania through the medium of participation. Participatory approaches are institutionalised as the way in which communities are brought into relations with the state and with national policies such as the reduction of poverty. Participatory approaches are not necessarily effective as a means of planning for development outcomes at local level, nor as a means through which communities can be made responsible for development in practice. Institutions through which participation is organised are popular with rural dwellers because they provide a space for the performance of village citizenship. They perform important work representationally in constituting the local as an object of development and local persons as afflicted by and responsible for poverty.
Health Status Measurement Instruments in Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is associated with primary respiratory impairment, disability and handicap, as well as with secondary impairments not necessarily confined to the respiratory system. Because the primary goals of managing patients with COPD include relief of dyspnea and the improvement of health-related quality of life (HRQL), a direct measurement of HRQL is important. Fourteen disease-specific and nine generic questionnaires (four health profiles and five utility measures) most commonly used to measure health status in patients with COPD were reviewed. The measures were classified according to their domain of interest, and their measurement properties - specifications, validity, reliability, responsiveness and interpretability - were described. This review suggests several findings. Currently used health status instruments usually refer to the patients’ perception of performance in three major domains of HRQL - somatic sensation, physical and occupational function, and psychological state. The choice of a questionnaire must be related to its purpose, with a clear distinction being made between its evaluative and discriminative function. In their evaluative function, only a few instruments fulfilled the criteria of responsiveness, and the interpretability of most questionnaires is limited. Generic questionnaires should not be used alone in clinical trials as evaluative instruments because of their inability to detect change over time. Further validation and improved interpretability of existing instruments would be of greater benefit to clinicians and scientists than the development of new questionnaires.
Transport processes and chemical evolution in steady accretion disk flows

We study the influence of mass transport processes on the chemical evolution in a protoplanetary accretion disk. Local transport processes by advection as well as global transport processes by diffusion are taken into account. Concerning the multi-component system only diffusion in the vertical direction was taken into account. Depending on the transport properties, different schemes are explored to couple/decouple the physical and chemical evolution. Our model is based on a simplified description of hydrodynamics in terms of a steady 1+1-D-α-disk model and includes the kinetics of an extended chemical network of about 250 species. We restrict our calculations to the inner planet formation zone within a distance to the central star of 10 AU. Vertical mixing does change the global chemical evolution as it is demonstrated in detail through a discussion of the chemistry of sulphur-bearing molecules. In addition, the influence of the local disk structure on the chemical evolution is analysed. Our results demonstrate that the chemical evolution is influenced globally by mass transport processes. However, in addition to mass transport processes, information about the local conditions, which determine the kinetics, is still needed in order to analyze the chemical evolution.
The Importance of Culture in ERP Adoption – A Case Study Analysis

The purpose of this study is to explore the importance of culture in (Enterprise Resource Planning) ERP adoption and to understand why ERP projects commonly fail. This study identifies culture as an underlying issue for such failures. The researchers use the Handy model of culture as a self-diagnosis tool for culture and organisational change that can be utilised as a facilitator for culture and ERP adoption success. This study uses a case study analysis as a qualitative approach to identify a diverse array of perceptions across hierarchal structures within a selected organisation who has recently adopted a cultural change program prior to adoption. Our study found that a cultural change led to enhanced communication, leadership and a sense of coherency across the whole organisation. We argue that if the organisation continues to improve its culture then successful ERP adoption could become a reality rather than an ideal.
Using Technovation For Service Classification: Some Industry Examples

Several service classifications based on servicespecific attributes, service delivery, channel strategies, marketing and management have evolved in response to the dynamics of the service industry. Service-specific attributes necessitate the need for strategic and operational focus, whereas technological advancements have significantly contributed towards providing different channels for delivery, increasing flexibility, improving quality and reducing time and distance. These advancements drive organizations to organize themselves and operate on a value chain level, in response to new ways in which services can be marketed, branded, operated and delivered. This creates important challenges and opportunities, which call for a realignment of strategic focuses, in particular with respect to the impact of technovation (technology, channels, and organizational structures) on services modus operandi and their resulting service classification. This paper builds on, and illustrates a recently developed classification scheme, referred to as the Services Cubicle, that transcends current industry boundaries and includes upcoming service business trends in technovation. A cross-section of service industry examples is used to clarify the resulting service classifications, taking into account deployment of varying degrees of technovation in that industry. These examples provide additional insights for service organizations, as well as a tool set to position, align, assess and validate the impact of their changing service offerings, whilst addressing the complexities of strategic alignment, value positioning, asset definition; as well as process, knowledge and relationship management.
Intravascular T-cell lymphoma in a patas monkey (Erythrocebus patas)

Abstract A 9-year-old female captive patas monkey (Erythrocebus patas) presented with poor general condition, inability to stand, petechiae, anaemia, thrombocytopenia, and leukocytosis. Due to poor response to treatment, the animal was euthanized 16 days later. Postmortem examination revealed hemorrhages in several organs and bilateral cerebral infarctions. Histologically, prominent accumulations of large neoplastic lymphocytes in cerebral and meningeal blood vessels were demonstrated within the lesions and in other organs (e.g., bone marrow, ovary, intestine). Immunohistochemically, neoplastic cells expressed CD3 and Ki-67. PCR revealed a lymphocryptovirus (LCV) infection, while Epstein–Barr nuclear antigen 2 (EBNA2) could not be demonstrated within neoplastic cells by means of immunohistochemistry. Based on the pathological findings, an intravascular lymphoma (IVL) of T-cell origin was diagnosed. To the authors' knowledge, this is the first report on this rare entity in a nonhuman primate.
