BACKGROUND Predicting habitats prone to favor disease transmission is challenging due to confounding information on habitats, reservoirs, and diseases. Comparative analysis, which aims at investigating ecological and evolutionary patterns among species, is a tool that may help. The emergence of zoonotic pathogens is a major health concern and is closely linked to habitat modifications by human ...
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
Taking advantage of a historical quasi-experiment in Sri Lanka, this paper provides evidence on the effects of land market restrictions on equilibrium wage and its spatial pattern. For identification, we exploit the effects of historical malaria prevalence on the incidence of land restrictions through the availability of ‘crown land’. The results show that there is important spatial heterogenei...
The agricultural uses of the Coordination Information on Environment Land Cover (CLC) dataset suffer from limitations such as temporal stationarity, low spatial resolution, broad and rather simplified grouping classes. study attempts to address these shortcomings, using test site Sperchios River catchment, Central Greece. Greek ‘branch’ Parcel Identification System, Beneficiaries’ Declarations ...
ارزیابی نابرابری محیطی در مواجهه به آلایندههای هوای شهری در سطح مناطق 22 گانه شهر تهران در سال 1390
Background and Objective: The aim of present study was to assess environmental inequality in long-term exposure to outdoor air pollution in 22 districts of Tehran in 2012. Materials and Methods: The present study is an ecological study and concentration index was used for assessment of inequality. In this study the amounts of pollutant concentrations (PM10, NO2, SO2) obtained were based on l...
The problem of abandoned land from mining activities is aggravated since the coal boom. Activities of excavating coal exscind natural vegetation and deposit stone on the natural land that modified the natural land contribute to waste farmlands. This paper presents the comparableness of SVMs method to artificial neural networks in the outlier detection problem of high dimensions. Experiments per...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
Human-driven land-use changes increasingly threaten biodiversity. In agricultural ecosystems, abandonment of former farmlands constitutes a major land-use shift. We examined the relationships between areas in which agriculture has been abandoned and the distribution records of threatened plant species across Japan. We selected 23 plant species that are currently identified as threatened but wer...
