![]() We propose a formula for calculating the dissolution resistance of taxa based on their wall thickness and size - two key parameters in dissolution resistance of a species. Most of the large Morozovella species such as Morozovella aequa, Morozovella formosa-gracilis, Morozovella velascoensis and Morozovella pasionensis, together with Acarinina nitida show intermediate dissolution resistance, whereas the small muricate Igorina species, the cancellate Subbotina velascoensis and the thin-walled Morozovella acuta and Morozovella occlusa are the most vulnerable species. At species level, the thick-walled Acarinina soldadoensis, Acarinina subsphaerica and the large Morozovella subbotinae are the most resistant species. We found that the large muricate Acarinina and Morozovella are most resistant, followed by the cancellate Subbotina and the small muricate Igorina, confirming results of previous work. Shell parameters such as wall thickness, porosity and pore size were determined through Scanning Electron Microscopy (SEM) and image analysis (JMicroVision). Two independent experiments were carried out, one focusing on gradual qualitative deterioration of taxa by dissolution and the other documenting the weight loss of taxa. The purposes of this study are: 1) assessing the effects of differential dissolution on upper Paleocene–lower Eocene planktic foraminiferal assemblages, at species level and within different biozones, to quantify dissolution susceptibility of genera and species 2) investigating the differences in shell characteristics 3) revealing the relationship between shell parameters and dissolution robustness of taxa, and 4) identifying the key shell parameter(s) influencing the dissolution susceptibility of foraminiferal taxa. Open Access This is an open access article under the CC BY-NC license.We investigated shell characteristics and differential dissolution susceptibility of planktic foraminiferal species derived from upper Paleocene and lower Eocene deep-sea sequences, Ocean Drilling Program (ODP) Site 865 (Allison Guyot) and Sites 1209B, 1210B and 1212A (Shatsky Rise) in the North Pacific Ocean.

In addition, these developments can help to increase the scope of scanning electron microscopes for solving a wide range of problems in medicine related to images in the field of diagnostics – medical introscopy. ![]() The presented automated program can recognize erythrocytes, calculate their number, diameters, areas, taking into account changes in morphology both in normal and pathological conditions, can work with a large amount of data with a significant acceleration of the calculation of parameters and with a greater approximation of these data to real ones, which significantly increases the efficiency of analysis in research, in the diagnosis and monitoring of therapy for CC and other types of diseases. This paper presents for the first time a method for studying the morphology of erythrocytes in patients with cancer based on SEM images of erythrocytes. It is shown that the use of this method already at the beginning of RT allows us to observe significant changes in the morphology of red blood cells of patients with cervical cancer, while the use the method of JMicroVision v1.2.7 states a slight difference of the diameters of red blood cells in the normal and pathological on the basis of the same experimental data. ![]() The article considers the study of the morphology of erythrocytes of patients with CC who were underwent RT using machine image recognition methods based on images of erythrocytes obtained by SEM. The aim of the study is to develop a technique for machine recognition of the shapes and sizes of scanning electron microscope (SEM) images of erythrocytes of patients with cervical cancer (CC) obtained on a SEM during radiation therapy (RT). ![]()
