Studies on the structure of the cuticle of Tylenchorhynchus martini swarmers with electron microscopes revealed abnormal disruptive and eruptive morphological changes in most layers. Drastic effects of swarming on cuticular structure were reflected in the partial dissolution of cortical layer and matrix and in the irregular cracking of cortical sublayers in sublateral areas of the body. The occ...

The structure of lexical entries and the status of lexical decomposition remain controversial. In the psycholinguistic literature, one aspect of this debate concerns the psychological reality of the morphological complexity difference between compound words (teacup) and single words (crescent). The present study investigates morphological decomposition in compound words using visual lexical dec...

We investigate the use of a morphological neural network to improve the performance of information retrieval systems. A morphological neural network is a neural network based on lattice algebra that is capable of solving decision boundary problems. The morphological neural network structure is one that theoretically can be easily applied to information retrieval. In this paper we propose a new ...

Neuronal spike detection is a technical challenge because of large amounts of background noise and contributions of many neurons to recorded signals. In this paper, we propose an automatic spike detection algorithm in which piecewise optimal morphological filters are designed to separate action potentials (spikes) from background noise. The structure elements of morphological filters are struct...

The present study aimed to investigate effects of the heavy metal Cd on the sperm morphological indices of Caspimyzon wagneri. The sperm were exposed to 0.01, 0.1, 1, 10, 100 and 1000 mg.L‑1 Cd for three minutes, three and 36 hours. The sperms exposed to Cd showed an increase in the length, width and surface of the head, flagella degradation and slightly flagella breakage.  With increase of Cd ...
