Abstract:

Uroscopy is the macroscopic examination of urine, and it is an important diagnostic tool in Unani medicine. The findings of uroscopy are linked with the humoral theory of medicine. Human Urine is the first fluid that was examined for medical purposes. There are seven parameters in uroscopy, each parameter is studied in detail and then the conclusion is drawn based on the findings of all. Examination of urinary sediments is one of the parameters in uroscopy. In urine, sediment is a denser and differentiable component from the watery constituent. The features of urinary sediment vary a lot in di

Chemical Profile of Plomin Bay SedimentsGranulometric, chemical, and leaching properties of sediments dredged in the Plomin Bay (Northern Adriatic Sea, Croatia) were investigated in order to asses the risk of remobilisation of heavy metals into the water column.

Analysis of variance confirmed the homogeneity of granulometric and elemental composition of the investigated sediment throughout its volume.

Beneficial use of dredged sediments, either in harbours or waterways, is based on their potential as alternative resources. Such sediments can be considered as bulk materials for industrial needs, which is predicated on their current waste status or meeting end-of-waste constraints.

This is particularly important for beneficial use projects focusing on climate change effects mitigation, such as flood protection works, coastline defence or littoral urban

The analyzed concentration of suspended sediments in the bottom layer during winter season increased higher than bottom layer during summer season in the marine national parks of Korea. This explains poor correlation between sediment concentration and attenuation coefficient during summer season (r²=0.74) and much high degree of correlation during winter season (r²=0.92). Relatively fine-sized and well-defined, monotonous size distribution may promote the correlation between concentration and attenuation coefficient due to optical homogeneity of particles during winter season.

Many approaches to magnetic data inversion are based on assumptions that source magnetization is homogeneous in direction and intensity. Such assumptions rarely can be verified with independent geologic information and are usually incorporated without further inquiry in the next steps of data interpretation. The use of magnetization direction invariants, such as the gradient intensity of the total field anomaly (equivalent to the amplitude of the analytical signal [ASA]) and the intensity of the anomalous vector field (IAVF), is effective for modeling sources with strong remanent magnetization

Abstract:

The area of Chroberz (southern Poland) poses questions of an interdisciplinary character comprising geomorphologic, sedimentation, and archaeological-historical problems. The main aim of this study was to identify the geomorphologic response to changes in the natural environment that took place in the area of the loess plateau (and its close vicinity) as a result of its settlement by man and of climate change. Periods of particularly intense human activity (land-use changes, deforestation, and agriculture) were recorded as changes in the type of sedimentation, i.e. organic sedimentation substi

Abstract:

The mechanism and enzymic activities responsible for the lipolysis of stored cytosolic triacylglycerol in liver and its re-esterification remain obscure. A candidate enzyme for lipolysis, a microsomal triacylglycerol hydrolase (TGH), was recently purified to homogeneity from pig liver and its kinetic properties were determined [Lehner and Verger (1997) Biochemistry 36, 1861–1868]. We have characterized the enzyme with regard to its species distribution, subcellular localization, developmental expression and reaction with lipase inhibitors.

The subject of this article is the development of composite materials using methods of activation of raw materials and activation of water. This article focuses on the electrical activation of water used in the preparation of ceramic mass. Electrochemical activation of water is carried out in an electrolyzer with anode and cathode zones with a constant magnetic field. The following works were carried out for the electroactivation of water. Water is placed in a container with electrodes (anode and cathode) and exposed to an electric field. At the first stage, before activation, the hydrogen ind

Abstract:

Water inrush is a major geological hazard for safe mining and tunnel construction. For the water inrush channel containing mud, sand, and other sediments, it is difficult to predict the change of permeability and water surge, which makes disaster prevention difficult. As a typical water inrush channel, a filled fracture under seepage-induced erosion needs to be focused. In this work, a numerical model for the evolution of flow in a filled fracture under seepage-induced erosion was established, which included the seepage velocity, hydraulic erosion, and permeability of the filling medium.

Activation of human platelets with thrombin transiently increases phosphorylation at558threonine of moesin as determined with phosphorylation state-specific antibodies. This specific modification is completely inhibited by the kinase inhibitor staurosporine and maximally promoted by the phosphatase inhibitor calyculin A, making it possible to purify the two forms of moesin to homogeneity. Blot overlay assays with F-actin probes labeled with either [32P]ATP or125I show that only phosphorylated moesin interacts with F-actin in total platelet lysates, in moesin antibody immunoprecipitates, and wh

To solve the sand problem during the depressurization of methane hydrate (MH), we proposed a method to build a porous grout body with sufficient permeability and strength around the wellbore through inhibitor pre-injection and grouting, and verified its effectiveness and potential in our previous research using artificial cores created with silica sand and alternative hydrates such as TBAB- hydrate and iso-butane hydrate. However, all of the artificial cores mentioned above were created with high homogeneity, injected, cured, and had their physical properties measured in the vertical direction
