Evaluation of mixing performance and validation of CFD simulations in baffled anaerobic digesters using radiotracer technique.

The anaerobic digesters find usage in treating the huge amount of waste such as trash, garbage, human waste and animal waste. The sustained performance of an anaerobic digester depends on the flow pattern and mixing behaviour in the digester. A cylindrical digester tank with vertical baffles can provide flow behaviour approaching that of a plug flow reactor.

Alpelisib-Induced Diabetic Ketoacidosis.

We present the third case of alpelisib-induced diabetic ketoacidosis. Alpelisib is an antineoplastic agent that inhibits phosphatidylinositol 3-kinase (PI3K), which plays a key role in multiple biological processes such as cell differentiation, proliferation, and survival. Thereby, the inhibition of this pathway should cause antitumor activity.

Investigation of flow dynamics of wastewater in a pilot-scale constructed wetland using radiotracer technique.

Constructed wetlands (CWs) are used for the treatment of wastewater by natural processes. Knowledge of the flow dynamics of wastewater through the CWs is required to evaluate their performance, operation and design. The residence time distribution (RTD) approach was used to evaluate the above-mentioned parameters in a CW.

Is this really just "fatigue"? A case series of immune-related central adrenal insufficiency secondary to immune checkpoint inhibitors.

While immunotherapy with programmed cell death protein 1 (PD1) checkpoint inhibition has shown promising activity against many tumor types, adverse events are common. Hypophysitis is a rare but serious immune-related event known to occur with anti-PD1 inhibition. It will become more prevalent as the usage of checkpoint inhibitors increases.

Application of thin layer activation technique for monitoring corrosion of carbon steel in hydrocarbon processing environment.

Acidic crude oil transportation and processing in petroleum refining and petrochemical operations cause corrosion in the pipelines and associated components. Corrosion monitoring is invariably required to test and prove operational reliability. Thin Layer Activation (TLA) technique is a nuclear technique used for measurement of corrosion and erosion of materials.

Recurrence of Graves' disease in ectopic thyroid tissue.

Eight months later, she presented with a mass on the right anterior neck that showed minimal growth over time. Her thyroid stimulating immunoglobulin and thyroid-stimulating hormone receptor antibody levels were consistently elevated and increasing.

Radiotracer investigation and modeling of an activated sludge system in a pulp and paper industry.

A radiotracer investigation was carried out in an activated sludge process (ASP) system of an effluent treatment plant in a pulp and paper industry. The system consists of an aeration tank and a secondary clarifier connected in series. The primary objective of the investigation was to measure mean hydraulic retention times (MHRTs) of wastewater and investigate the hydraulic performance of the ASP.

Sialendoscopy in the Management of Radioiodine Induced Sialadenitis: A Systematic Review.

Objectives: Salivary gland dysfunction as a consequence of radioiodide ablation is present in as many as two-thirds of patients, and unfortunately, many of these individuals do not respond to conservative measures. Sialendoscopy as a minimally invasive therapeutic modality may have utility in the treatment of radioiodide induced sialadenitis (RAIS). Our aim was to explore whether sialendoscopy resulted in clinical improvement in patients with RAIS.

Hypothyroidism in Cancer Patients on Immune Checkpoint Inhibitors with anti-PD1 Agents: Insights on Underlying Mechanisms.

Immune therapy using monoclonal antibodies against cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed cell death 1 receptor (PD-1) for various cancers have been reported to cause thyroid dysfunction. Little is known, however, about the underlying pathogenic mechanisms and the course of hypothyroidism that subsequently develops. In this report, we use the change in thyroglobulin and thyroid antibody levels in patients on immune therapy who develop hypothyroidism to better understand its pathogenesis as well as examine the status of hypothyroidism in the long term.

Discharge rate measurements in a canal using radiotracer methods.

Discharge rates of water were measured in a canal using radiotracer methods with an objective to validate the efficacy of Concrete Volute Pumps (CVPs) installed at various pumping stations along the canal. Pulse velocity and dilution methods were applied to measure the discharge rates using Iodine-131 as a radiotracer. The discharge rate measured in one of the sections of the canal using the pulse velocity method was found to be 22.
