Drosophila neuroblasts divide asymmetrically by aligning their mitotic spindle with cortical cell polarity to generate distinct sibling cell types. Neuroblasts asymmetrically localize G i, Pins, and Mud proteins; Pins/G i direct cortical polarity, whereas Mud is required for spindle orientation. It is currently unknown how G i–Pins–Mud binding is regulated to link cortical polarity with spindle...

the geothermal phenomena in the area nearby the euganean hills (near padua, in italy) areknown and exploited for therapeutic purposes since ancient times, and recently also for aesthetic purposes.this paper presents the first characterization of the radionuclides content in the euganean thermal waters and mud, extended to a great number of spas. in particular the radionuclides content of both t...

The porosity and methane adsorption capacity of shale used to estimate gas in place (GIP) are affected both by moisture oil residing the pore structure, as well naturally present from maturation, which can include contaminant drilling mud fluids for drilling. To demonstrate impact extractable on dry moisture-equilibrated shales, two overmature shales China (SH1, SH2) lower mature UK (BS3, GH4) ...

Environmental dusts settle on surfaces and influence the performance of concentrated solar energy harvesting devices, such as aluminum troughs. The characteristics of environmental dust and the effects of mud formed from the dust particles as a result of water condensing in humid air conditions on an aluminum wafer surface are examined. The dissolution of alkaline and alkaline earth compounds i...

mud volcanoes are defined as main elements of geological structures and ways through and within which buried argillaceous loose sediments and lithified rocks. the gharniaregh tappeh and naftelijeh mud volcanoes are the most attractive geomorphological phenomena in continental which appear along the eastern coast of the caspian sea. the naftelijeh mud volcano is more active than gharniaregh–tapp...

This paper reports the preparation of sulphur polymer cements (SPCs) incorporating waste ilmenite mud for use in concrete construction works. The ilmenite mud raw material and the mud-containing SPCs (IMC-SPCs) were characterised physico-chemically and radiologically. The optimal IMC-SPC mixture had a sulphur/mud ratio (w/w) of 1.05 (mud dose 20 wt%); this cement showed the greatest compressive...

This work investigates the impact of mud from a zinc-plating plant and zeolite saturated with zinc on early hydration processes of ordinary Portland cement. During the first 48 hours of hydration, the addition of mud significantly affects the cement hydration kinetics. The partial replacement of cement with zeolite saturated with zinc ions, reduces the negative impact of mud on the hydration pr...

Goals include the development of models and methods that explain observed material and acoustic properties of different physical types of shallow-ocean mud sediments. Other goals are to assess prior data relating to the acoustic properties of mud and to provide guidance in the development and interpretation of experiments. A related goal is to construct models that will guide inversion techniqu...
