Abstract:
In knowledge structure theory (KST), an individual’s knowledge state represents the items that the individual can completely solve. Based on the differences in individuals’ latent cognitive competence, polytomous knowledge states can be used to partially represent individuals to solve items. This paper explores the construction of polytomous knowledge states and polytomous knowledge structures on a polytomous knowledge domain Q×L. A quasi-ordinal polytomous knowledge space and a polytomous knowledge space can be induced by two different entail relations, respectively. When the polytomous knowl

Abstract:
The classic selection of plants for landscaping the urban environment is a rather labor-intensive process involving the use of a large number of reference materials, atlases and plant catalogs. It is necessary to consider various characteristics of plants, taking into account their decorativeness, mutual compatibility, survival in the natural conditions of each region, etc. The purpose of the research was developing a polytomous key and creating it using a modern computer program to simplify the selection of plants according to decorative, phenotypic and phenological characteristics for landsc

Abstract:
Pin nematodes of the genus Paratylenchus comprise 140 species. This group of nematodes is characterized by a quite homogeneous morphology and cosmopolitan distribution and is prevalent in cultivated and natural soil ecosystems. The present study describes the first interactive and illustrated web-assisted polytomous identification key for the genus Paratylenchus. The updated Paratylenchus species polytomous key was based on a wide list of 24 diagnostic characters generated for the 140 species comprising this genus. Here we developed a web-assisted method to achieve an easy and accurate Paratyl

Carpological keys are of great practical importance. So they are important in all cases where plant identification is required. In this context, some attempts are made to compile numerical polytomous keys that allow us to define the species studied using their morphological signs.

This group is one of the largest withinthe family Phytoseiidae and the sub-family Typhlodrominae, with nearly 350 species currently recognised worldwide. Noidentification tool of these species exists at the world level, which makes their identification very difficult and unsecure.Thirty five characters were used to characterise each of the 343 species.

This retrospective study investigated, in two cohorts of subjects living in Karachi Pakistan and awaiting treatment for oral squamous cell carcinoma (OSCC), the variables related to diagnostic delay ascribable to the patient, with particular reference to the cognitive and psychological ones. A total of 156 patients with OSCC (mean age: 62 years, M/F: 2.39 : 1) were recruited at the Agha Khan Hospital Karachi. Risk factors related to patient delay included: socio demographic, health-related, cognitive and psychological variables. The analysis was conducted by considering two different delay ran

Abstract:
Hirschmanniella mucronatapopulations isolated from two Cambodian provinces were characterised using morphological, morphometric and molecular criteria. Examination of 1024 specimens from 60 different paddy fields revealed high intraspecific variation in morphology and morphometrics, especially in tail terminus shape and stylet length. Sequence results confirmed that morphologically divergent individuals represent a single species, suggesting that neglecting morphological variation has led to an overestimation ofHirschmannielladiversity in former studies.

Present taxonomic status and synonymy of the didelphic species of the genus Radopholus Thorne are considered. A monoentry polytomous key to Radopholus is presented, as well as the rows of characters and a matrix of species and characters which were used for the phylogenetic analysis in the PAUP package. Phylogenetic tree of the genus includes four main species groups (clusters); all the species of the Indo-Asian origin (not inhabiting Australia and Oceania) form a separate monophyletic branch.
