Investigations on two-phase gas/liquid flow in pipes have been under study for nearly six decades. These studies have significantly assisted in managing fluid flow in the wellbore and surface networks, leading to the separation of phases and transmission of oil and gas into the market. This study summarizes some of the main lessons learned in flow through wellbores. Besides understanding some of the fundamental principles, we focused on the practical items of interest: Conventional production scenarios for oil and [...]

Genes encoding for proteins associated with the plasma membrane, referred to as the membranome, have long been recognized to play an important role in the development and maintenance of glioblastoma multiforme (GBM). GBM cell lines are commonly used to mimic tumors for in vitro experiments, but the extent to which they resemble GBM tumors in relation to the membranome is unclear. The present study explores the resemblance of GBM cell lines to primary tumors regarding membranome expression. Gene expression data was [...]

Regardless of their size, supported gold nanoparticles are largely used for liquid-phase oxidation reactions. Small gold nanoparticles exhibit good performance during the reduction of organic compounds. The direct reduction of carboxylic acid to aldehyde is a famous and familiar reaction in the field of organic chemistry and is considered as one of the fundamental chemical transformations. Herein, we present Au/hydrotalcite, Au/MgO, and Au/Al2O3 systems as heterogeneous versatile catalysts to realize the oxidation [...]

Study participants included 325 undergraduate students and 100 staff members at a large tri-campus university in the U.S. Participants completed surveys with self-report measures assessing mindfulness, perceptions of stress, emotion regula [...]

Usually, everyday meals constitute materials and ingredients for food preparation derived from different agricultural sources. Although most customers are aware of the benefits of a balanced diet, they mainly focus on a diet based on the daily requirements of protein, fat, and carbohydrates in their meals. However, the vital aspect of the including dietary fibers in diets is overlooked, which is equally important as is the daily requirement of calories and protein intake for maintaining the muscle mass. Some societ [...]

Portal hypertension often occurs transiently with injection of islet cells into the portal system during total pancreatectomy-islet autotransplantation (TPIAT). We describe a TPIAT patient with non-cirrhotic portal hypertension (NCPH) two years after surgery initially identified with esophageal varices on upper endoscopy. The underlying mechanism for the development of NCPH after TPIAT is unclear but infectious and immune-related pathways have been proposed. Management of NCPH is primarily treatment of complication [...]

Donor cell-derived leukaemia (DCL) is an uncommon complication of allogeneic hematopoietic stem cell transplantation (HSCT). DCL might represent up to 5% of the post-HSCT disease relapses, but case numbers reported in the literature might underestimate the frequency. The leukemogenesis of DCL is not well understood due to the limited numbers of cases reported and lack of detailed molecular genetic information from recipients and donors. Although many theories have been proposed for leukemogenesis of DCL, the underl [...]

There are several definitions of sympathy, empathy, and compassion on the internet. I have chosen the above definitions to emphasize their salient differences, for the following reason: In medical school, in the early 1960s, we were taught not to sympathize with patients, but to empathize: By empathizing, one can retain some professional objectivity toward the patient, in order to be of some help. To sympathize, on the other hand, was to immerse oneself in the patient’s suffering and lose one’s professional per [...]

Left ventricular assist devices (LVADs) improve quality of life in end-stage heart failure patients but a frequent complication is Right heart failure (RHF) causing significant morbidity and mortality. This review article discusses key issues that need to be considered in the assessment and clinical management of RHF in LVAD patients including the use of Right Ventricle (RV) support devices and off-label LVADs as temporary or permanent RV support.

A set of empirical models which accounts for the formation of gas phase polychlorinated dibenzo-p-dioxins and furans (PCDD and PCDF), and solid phase PCDD/F by the de novo mechanism is described.In each case, competing formation and destruction reactions are considered to operate.The effect of the time-temperature history on their formation is then examined.At high temperatures, steady-state is reached in fractions of a second, resulting in the observed low product concentrations.Rapid cooling as found in furnaces [...]
