Biosynthetic and degradative pathways of glycocalyx components are largely unknown in Paramecium and in some related parasitic protozoa. We isolated cell surface (glyco-)proteins, i.e., surface antigens (SAg) and used them in the native (nSAg) or denatured (dSAg) state to produce antibodies (AB) for immunolocalization by confocal imaging and by quantitative immunogold EM-labeling of ultrathin s...

The submodules with the property of the title ( a submodule $N$ of an $R$-module $M$ is called strongly dense in $M$, denoted by $Nleq_{sd}M$, if for any index set $I$, $prod _{I}Nleq_{d}prod _{I}M$) are introduced and fully investigated. It is shown that for each submodule $N$ of $M$ there exists the smallest subset $D'subseteq M$ such that $N+D'$ is a strongly dense submodule of $M$ and $D'bi...

We analyzed the outer membrane (OM) ultrastructure of four pathogenic members of the family Spirochaetaceae by freeze fracture. The OM of Treponema pallidum subsp. pertenue contained a low intramembranous particle concentration, indicating that it contains few OM transmembrane proteins. The concave OM fracture faces of Treponema hyodysenteriae and Borrelia burgdorferi contained dense population...

[1] In order to improve discrete fracture network (DFN) models, which are increasingly required into groundwater and rock mechanics applications, we propose a new DFN modeling based on the evolution of fracture network formation—nucleation, growth, and arrest—with simplified mechanical rules. The central idea of the model relies on the mechanical role played by large fractures in stopping the g...

‎In this paper we take $mathcal A$ to be the category {bf Pos-S}‎ ‎of $S$-posets‎, ‎for a posemigroup $S$‎, ${mathcal M}_{pd}$ to‎ ‎be the class of partially ordered sequantially-dense‎ ‎monomorphisms and study the categorical properties‎, ‎such as‎ ‎limits and colimits‎, ‎of this class‎. ‎These properties are usually‎ ‎needed to study the homological notions‎, ‎such as injectivity‎, ‎of‎ ‎$S$-...

[1] Large-scale (2.5 km by 2.5 km) simulations of fluid flow and solute transport through low-permeability fractured rock are assessed to determine suitability for hosting a nuclear waste repository. Multiple realizations of fracture networks with statistically realistic features are generated according to established methods. A novel continuum method provides a basis for solving flow and simul...

INTRODUCTION Osteopetrosis is a group of conditions characterized by defects in the osteoclastic function of the bone resulting in defective bone resorption. Clinically, the condition is characterized by a dense, sclerotic, deformed bone which, despite an increased density observable by radiography, often results in an increased propensity to fracture and delayed union. CASE PRESENTATION We r...

A dense Al-SiCp nanocomposite coating with high volume fraction of nano SiCp reinforcement (60 vol.%) was fabricated through cold spraying deposition milled Al-60SiCp powder in the present paper. Microstructure evolution during ball milling process, microstructure characteristics and hardness sprayed were studied. Al particles underwent fracture deformation SiC evenly distributed soft base mate...
