Limpets are commonly found on wave-swept rocky shores, where they may be subjected to water velocities in excess of 20 m s(-1). These extreme flows can impose large forces (lift and drag), challenging the animal's ability to adhere to the substratum. It is commonly thought that the conical shape of limpet shells has evolved in part to reduce these hydrodynamic forces while providing a large ape...

The microstructure and its crystallographic aspect of the shell of a limpet, Lottiakogamogai, have been investigated, as the first step to clarify the mechanism of shell formation in limpet. The shell consists of five distinct layers stacked along the shell thickness direction. Transmission electron microscopy (TEM) with the focused ion beam (FIB) sample preparation technique was primarily adop...

Cyclic di-AMP is a recently discovered signaling molecule which regulates various aspects of bacterial physiology and virulence. Here we report the characterization of c-di-AMP synthesizing and hydrolyzing proteins from Mycobacterium tuberculosis. Recombinant Rv3586 (MtbDisA) can synthesize c-di-AMP from ATP through the diadenylate cyclase activity. Detailed biochemical characterization of the ...

Temporal changes in abundance, size, productivity, resource allocation and light requirements of a subtidal eelgrass (Zostera marina L.) population were followed for 2 yr after the September 1993 appearance of a previously rare oval form of the commensal limpet Tectura depicta (Berry) in Monterey Bay, California, USA. By exclusively targeting the epidermis, limpet grazing impaired photosyntheti...

Phytocompounds of natural origin are not only a potential source for maintaining human health but also the supplement nutrients long period survival. In recent years, essential oils and herbal extracts have attracted great scientific interest due to its as antioxidants biologically active compounds, especially in last decade with more intensive studies chemotherapies antioxidant activity. The m...

In this paper, according to G-Brownian motion and other related concepts properties, we define multiple Itô integrals driven by G-Lévy process. By using the G-Itô formula properties of G-expectation, two main theorems about integral are obtained proved. These provide powerful help for subsequent research on jump

Abstract. We investigate the impact of so-called energetic particle precipitation (EPP) indirect effect on lower stratospheric ozone, ClO, and ClONO2 in Antarctic springtime. use observations from Microwave Limb Sounder (MLS) Ozone Monitoring Instrument (OMI) Aura, Atmospheric Chemistry Experiment – Fourier Transform Spectrometer (ACE-FTS) SCISAT, Michelson Interferometer for Passive Sounding (...

This research aims to make a parallel and determine the symmetry between main male characters of Shakespearian play “The tragedy Hamlet, Prince Denmark”. For this purpose, each important character is analysed in-depth with use primary text other critical views. The approach used in paper was based on source, by employment quotes lines, verses how they manage be interpreted regarding portrayal c...

Abstract. In this study we report the synthesis of single crystals burbankite, Na3Ca2La(CO3)5, at 5 GPa and 1073 K. The structural evolution, bulk modulus thermal expansion burbankite were studied determined by two separate high-pressure (0–7.07(5) GPa) high-temperature (298–746 K) in situ single-crystal X-ray diffraction experiments. refined parameters a second-order Birch–Murnaghan equation s...
