Shallow groundwater near a deep-well CO storage site-15 years of stable water quality for agricultural use.

Injecting CO into deep geological formations can be an effective carbon removal and storage technology to mitigate global climate change. Interaction of injected CO with rock formations changes pH and hydrochemistry within the deep injection zone (> 800 m depth). However, cap rocks and multiple tight aquitards typically act as barriers to protect the shallow aquifer from changes in the injection zone.

Amphiphilic materials with magnetic properties in combination with magnetic suction devices allow for automated sample preparation. However, conventional synthesis methods are cumbersome and not suitable for the mass production of the material.

The effect of the occipital sinus on the torcular Herophili and neighboring structures.

Cerebellar pial arteriovenous fistula (PAVF) in adults presenting with congestive edema of the brainstem and cervical cord has rarely been reported. Here, we report such a case. A 59-year-old man presented with progressive weakness and numbness of the limbs and hiccups for 6 months.

Endovascular treatment of middle cerebral artery aneurysms: current status and future prospects.

Middle cerebral artery (MCA) aneurysms are complex and widely distributed throughout the course of the MCA. Various types of aneurysms can occur in the MCA. Ruptured as well as unruptured MCA aneurysms may require treatment to avoid bleeding or rebleeding.

Integrating major ion geochemistry, stable isotopes (O, H) and radioactive isotopes (Rn, C, Cl, H) to understand the interaction between catchment waters and an intermittent river.

Determining the locations and sources of baseflow and the transit times of water is important for understanding catchment behaviour and functioning. Major ion geochemistry, stable isotopes (O and H), and radioisotopes (Rn, H, C, and Cl) were used to investigate the sources and transit times of water in the upper catchment of the intermittent Avoca River in southeast Australia. Rn activities and Cl concentrations implied the presence of baseflow inputs and the distribution was mainly controlled by local topography.

Endovascular treatment of a supraclinoid internal carotid artery fenestration aneurysm: A case report and literature review.

upraclinoid internal carotid artery (ICA) fenestration aneurysm is rare. Except for open surgery, endovascular treatment (EVT) is considered an alternative for such an aneurysm. However, experience with this procedure is lacking.

Transarterial embolization of dural arteriovenous fistula of the inferior petrosal sinus: A report of two cases.

Dural arteriovenous fistula (DAVF) of the inferior petrosal sinus (IPS) is very unusual. Endovascular embolization is a good option for the treatment of DAVF. Until now, DAVFs of the IPS have only been reported sporadically.

Wearable Continuous Blood Pressure Monitoring Devices Based on Pulse Wave Transit Time and Pulse Arrival Time: A Review.

Continuous blood pressure (BP) monitoring is of great significance for the real-time monitoring and early prevention of cardiovascular diseases. Recently, wearable BP monitoring devices have made great progress in the development of daily BP monitoring because they adapt to long-term and high-comfort wear requirements. However, the research and development of wearable continuous BP monitoring devices still face great challenges such as obvious motion noise and slow dynamic response speeds.

Parent artery occlusion for ruptured aneurysms in moyamoya vessels or on collaterals.

Background: Aneurysms in moyamoya vessels or on collaterals are difficult to treat. Parent artery occlusion (PAO) endovascular treatment (EVT) is often the last resort, but the safety and efficacy of this approach need to be evaluated.

Materials And Methods: A retrospective study was performed on patients admitted to our hospital who were diagnosed with unilateral or bilateral moyamoya disease (MMD) associated with ruptured aneurysms in moyamoya vessels or on collaterals.

Transfemoral trans-facial vein-superior ophthalmic vein to embolize cavernous sinus dural arteriovenous fistulas.

Cavernous sinus dural arteriovenous fistula (CS-DAVF) is an abnormal communication between the CS and dural arteries from the internal carotid artery and external carotid artery. CS-DAVFs are not uncommon. The preferred treatment for most CS-DAVFs is transvenous embolization (TVE), which can achieve a high cure rate with few complications.

CTA Study of Ruptured Aneurysms of the Posterior Communicating Artery.

Background: Only a few reported studies have used computed tomography angiography (CTA) to image ruptured aneurysms at the junction of the internal carotid artery (ICA) and posterior communicating artery (PcomA) in the context of the adjacent arteries. Therefore, we performed such a study using a GE Workstation.

Methods: The parameters of each aneurysm and its adjacent arteries were measured.

Endovascular treatment of main trunk aneurysms in the residual anterior circulation in moyamoya disease.

Result: The 35 patients were aged 38-77 years (mean, 56.

Preparation of Bisphenol-A and Polydimethylsiloxane (PDMS) Block Copolycarbonates by Melt Polycondensation: Effects of PDMS Chain Length on Conversion and Miscibility.

This study aimed to improve polydimethylsiloxane (PDMS) conversion in the preparation of polycarbonate (PC)-polydimethylsiloxane (PDMS) copolymer through melt polycondensation. We examined the transesterification process of PDMS with diphenyl carbonate (DPC) and its copolymerization products with bisphenol-A (BPA) for different chain lengths of PDMS. The key factors affecting PDMS conversion were investigated.

Using geochemistry to identify and quantify the sources, distribution, and fluxes of baseflow to an intermittent river impacted by climate change: The upper Wimmera River, southeast Australia.

Documenting the distribution, sources and fluxes of baseflow discharge into rivers is important for their management and for maintaining ecosystem health. This study uses major ion geochemistry, Rn, and H to differentiate between the input of low-salinity near-river waters (bank storage and return waters and/or interflow) and regional groundwater in an intermittent river from southeast Australia that is undergoing long-term changes in flow resulting from climate change. Baseflow discharge calculated by Rn mass balance was up to 1.

Adaptive Complex Variational Mode Decomposition for Micro-Motion Signal Processing Applications.

In order to suppress the strong clutter component and separate the effective fretting component from narrow-band radar echo, a method based on complex variational mode decomposition (CVMD) is proposed in this paper. The CVMD is extended from variational mode decomposition (VMD), which is a recently introduced technique for adaptive signal decomposition, limited to only dealing with the real signal. Thus, the VMD is extended from the real domain to the complex domain firstly.

As a chronic metabolic disease, diabetes mellitus (DM) is broadly characterized by elevated levels of blood glucose. Novel epidemiological studies demonstrate that some diabetic patients have an increased risk of developing dementia compared with healthy individuals. Alzheimer's disease (AD) is the most frequent cause of dementia and leads to major progressive deficits in memory and cognitive function.
