Abstract:

AbstractThe exploration of unconsolidated and semi-consolidated strata is generally undertaken using shell and auger and continuous flight augering techniques. These methods have serious limitations, especially when accurate sampling is required below the water table.To improve the reliability of samples British Industrial Sand Ltd. have developed a drill bit for use with reverse circulation drilling. When used in combination with a non-return valve this method allows continuous drilling and sampling both above and below the water table.Comparisons with other drilling techniques show that the

Abstract:

Acute disturbed cerebral circulation is the second leading cause of death around the world. Carotid stenosis is a cause of acute disturbed cerebral circulation in approximately 25 % of cases. At present, carotid endarterectomy is one of the most frequently performed vascular reconstructions. This is due to the high efficiency of the surgery in the correction of cerebral circulation and prevention of acute disturbances of cerebral circulation. The problem of the further disease progression still remains topical despite the method of intervention and plastic material applied, as restenosis is di

Introduction: Sickle cell disease (SCD) is a genetic condition marked by abnormal red blood cell morphologies and high levels of hemolysis leading to chronic and severe thromboembolic complications. The biomechanics of the sickle red blood cell (sRBC) has primarily been studied within the context of venous circulation where RBCs adopt their characteristic “sickled” shape. However, much remains to be understood about how the sRBC reacts to the distinct flow patterns found in arterial circulation and its relation to the significant burden of arterial disease observed in SCD.

Researchers from Chalmers Insitute of Technology (CTH) and the University of Freiburg have proposed an interesting technique that enables chronic wounds to heal faster than ever.  Medical conditions like diabetes, cancer, disturbed blood circulation, and spinal injuries can sometimes impair our body’s natural ability to heal wounds. Patients who live with such conditions often experience wounds that don’t heal.These unrepaired chronic wounds become a source of infection and sometimes even lead to amputations, making patients’ lives very difficult.

Abstract:

The gut microbiota produces a number of biologically active compounds that may have both, positive and negative effects on health. To enter the circulation, microbiota-derived molecules need to pass the gut-blood barrier (GBB), a complex multi-layer system that prevents the free passage form the gut lumen to the blood. The integrity and permeability of the GBB depends on numerous factors, and may be disturbed in gastrointestinal, metabolic, cardiovascular and other diseases. An increased permeability of the GBB results in easier access of gut-derived molecules to the circulation. This may exer

Aerobic glycolysis in the photoreceptors also leads to a high rate of production of lactate which is transported out of the subretinal space to the choroidal circulation by the RPE. Lactate

Abstract Northern Hemisphere ozone underwent a monotonic decline during the 1980s and 1990s. Systematic changes associated with that trend are shown to have a close relationship to random changes of ozone. These two components of interannual variability share a common structure. In it, ozone changes at high latitude are compensated at low latitude by changes of opposite sign. The out-of-phase relationship between ozone changes at high and low latitudes is consistent with a change of the residual mean circulation of the stratosphere, and so is the seasonality of systematic changes.

Abstract:

The purpose of space weather is the systemic study of the Sun–Earth system, in order to determine the impact of solar events on the electromagnetic environment of the Earth. This article proposes a new transdisciplinary approach of the Sun–Earth system based on the universal physical process of the dynamo. The dynamo process is based on two important parameters of the different plasmas of the Sun–Earth system, the motion and the magnetic field. There are four permanent dynamos in the Sun–Earth system: the solar dynamo, the Earth dynamo, the solar wind-magnetosphere dynamo, and the ionospheric

Abstract:

Fetal growth retardation (FGR) is a complication of pregnancy that determines perinatal morbidity and mortality. It is a complex and multifaceted medical problem that does not lose its relevance. Impaired fetal development and delayed growth result from various etiopathogenesis of pathological processes occurring in the "mother–placenta–fetus" interface. Thrombophilia is one of the factors that can initiate disturbed placental function and the utero-placental blood flow. Here we describe the clinical FGR variants and etiopathogenetic factors of developing this complication of pregnancy (placen

Abstract:

The aim of this review is to estimate contribution of orthostatic circulatory changes to the development of vascular disorders. In the XXI century, the cardiovascular disorders remain a most widespread pathology responsible for the high mortality and disablement rate throughout the world. Their main risk factors have been identified, but the influence of gravity on the cardiovascular system is usually disregarded even though it exerts an appreciable effect of special importance for neurohormonal regulation. Disturbed regulation of orthostatic changes in circulation manifest as orthostatic arte

Abstract:

Mechanized timber harvesting is cost efficient and highly productive. However, mechanized harvesting operations are often associated with several environmental problems, including soil compaction and disturbance. Soil compaction impedes air circulation between the soil and atmosphere, which in turn results in increased concentrations of CO2 within soil pores. In this study, we investigated the impact of forest machine traffic on soil conditions to determine soil CO2 efflux (Fc), and soil CO2 concentrations (Sc). Field measurements included soil bulk density (BD), soil temperature (ST), soil wa

Abstract:

Phthalates used as plasticizers have become a part of human life because of their important role in various industries. Human exposure to these compounds is unavoidable, and therefore their mechanisms of toxicity should be investigated. Due to their structure and function, human erythrocytes are increasingly used as a cell model for testing the in vitro toxicity of various xenobiotics. Therefore, the purpose of our study was to assess the effect of selected phthalates on methemoglobin (metHb), reactive oxygen species (ROS) including hydroxyl radical levels, as well as the activity of antioxida

Abstract:

The present literature review concerns hydrodynamics and the development of concomitant disorders in the patients suffering cervical spine osteochondrosis. Roughly 40% of such patients present with a moderate reduction of intraocular pressure at the affected side as evidenced by the results of clinical examination, computed and magnetic resonance tomography and neuropathological examination. These observations are consistent with the data on the pathogenetic mechanisms underlying this pathology. In the majority of the patients, reduction of intraocular pressure is associated with lens dilatati

Type 2 diabetes mellitus (T2DM) is a complex metabolic disorder frequently accompanied by cognitive impairment. Contributing factors such as modern lifestyle, genetic predisposition, and gene environmental interactions have been postulated, but the pathogenesis remains unclear. In this study, we attempt to investigate the potential mechanisms and interventions underlying T2DM-induced cognitive deficits from the brain–gut axis perspective.

Abstract. Atmospheric gravity waves are a major cause of uncertainty in atmosphere general circulation models. This uncertainty affects regional climate projections and seasonal weather predictions. Improving the representation of gravity waves in general circulation models is therefore of primary interest. In this regard, measurements providing an accurate 3-D characterization of gravity waves are needed. Using the Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA), the first airborne implementation of a novel infrared limb imaging technique, a gravity wave event over Ice
