Improving the Engine Efficiency Using a New Combined Refrigeration Cycle for Low-Temperature Heat Source (Waste Heat Recovery)

Received: 19 April 2022;  Published: 08 June 2022;  doi: 10.21926/jept.2202020

Abstract

Passenger and commercial internal combustion engines have relatively large dissipated thermal energy sources that can be used for initiating thermodynamic refrigeration cycles at low temperatures while improving engine efficiency. Researchers have focused on combined power-refrigeration cycles in past studies. This paper presents the operation and performance of a new combined refrigeration system driven by waste heat recovery within the internal combustion engines. For this purpose, the effects of several paramete [...]

Evaluation of a Virtual Compassionate Living Group for Patients with Chronic Pain

Received: 26 May 2022;  Published: 14 November 2022;  doi: 10.21926/obm.icm.2204050

Abstract

Chronic pain affects around 28 million people in the UK. Those living with chronic pain can frequently experience internalised self-stigma and negative self-evaluations as a result of the pain itself and due to difficult life experiences. Previous research has found Compassion Focused Therapy to be effective for people living with long term health conditions like chronic pain. The current study sought to evaluate a routine Virtual Compassionate Living Group for patients with chronic pain on the measures of self-com [...]

Nonalcoholic Fatty Liver Disease and Inflammatory Bowel Disease: Complex Interactions, Evaluations, and Management Decisions

Received: 31 January 2019;  Published: 28 June 2019;  doi: 10.21926/obm.hg.1902025

Abstract

Diseases of the liver are commonly encountered in patients with Inflammatory Bowel Disease (IBD). While the differential for IBD patients with elevated liver associated enzymes is broad, it is similar to that of the general population. This differential includes including non-alcoholic fatty liver disease (NAFLD), the most common liver disease in North America. When initial work-up for elevated liver associated enzymes is negative and patients have steatosis on ultrasound, we counsel IBD patients aggressively about [...]

Quantum and Component Analysis of P3a and P3b from Auditory Single Trial ERPs Differentiates Borderline Personality Disorder from Schizophrenia

Received: 09 April 2023;  Published: 13 July 2023;  doi: 10.21926/obm.neurobiol.2303174

Abstract

Traditional approaches to EEG modelling use the methods of classical physics to reconstruct scalp potentials in terms of explicit physical models of cortical neuron ensembles. The principal difficulty with such approaches is that the multiplicity of cellular processes, with an intricate array of deterministic and random influencing factors, prevents the creation of consistent biophysical parameter sets. An original, empirically testable solution has been achieved in our previous studies by a radical departure from [...]

Research and Application of Modified ZSM-5 for the Process of Alkylation of Oil Distillate Fractions

Received: 20 April 2023;  Published: 10 August 2023;  doi: 10.21926/cr.2303021

Abstract

In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O. X-ray diffraction studies were conducted on zeolite ZSM-5, zirconyl chloride modifier ZrOCl2∙6H2O, and modified zeolite ZSM-5-ZrO2, which was calcined at temperatures of 200, 400, and 550°C. The results revealed that the phase composition of modified ZSM-5-ZrO2 zeolite samples varied depending on the calcinatio [...]

Bilateral Corneal Perforation in a Patient with Chronic Ocular Graft-Versus-Host Disease: A Case Report and Literature Review

Received: 17 June 2022;  Published: 02 August 2022;  doi: 10.21926/obm.transplant.2203164

Abstract

Graft-versus-host disease (GVHD) is a serious complication that may occur in patients receiving allogeneic hematopoietic stem cell transplant (HSCT). GVHD occurs because of the immunological reaction between the donor’s T cells and the recipient’s antigens; GVHD may develop in different tissues, including the eye. Corneal perforation is an uncommon but vision-threatening manifestation of GVHD. We reported the case of a 65-year-old male patient who developed corneal perforation sequentially in both eyes 3 years afte [...]

Brain Imaging Studies Using Deep Neural Networks in the Detection of Alzheimer's Disease

Received: 29 June 2022;  Published: 03 January 2023;  doi: 10.21926/obm.geriatr.2301220

Abstract

The increasing incidence of adult-onset dementia disorders and primarily Alzheimer’s disease (AD) among the aging population around the world is increasing the social and economic burden on society and healthcare systems. This paper presents three neural networking algorithms: MobileNet, Artificial Neural Networks (ANN), and DenseNet for AD classification based on MRI imaging data. The results of each model were compared in terms of performance metrics such as accuracy, true positive rate, and receiver operating cu [...]

The Complete Chloroplast Genome Sequence of Actinidia arguta var. purpurea

Received: 16 October 2023;  Published: 24 November 2023;  doi: 10.21926/obm.genet.2304203

Abstract

In this study, we report the complete chloroplast genome of Actinidia arguta var. purpurea. The chloroplast genome is 157,369 bp long as the circular (GC ratio is 37.22%). It has four subregions: a large single-copy (LSC) region of 88,609 bp, a small single-copy (SSC) region of 20,470 bp, and two inverted repeat regions (IRs) of 24,145 bp in each. The chloroplast genome of A. arguta var. purpurea contains a total of 113 unique genes, which are 79 protein-coding genes, 4 rRNA genes, and 3 [...]

Clinical Practice Guidelines About Screening for Disruptive Behavior Problems at Well-Child Visits: A Rapid Review of the Literature on the Accuracy of Parents’ Behavioral Concerns

Received: 08 March 2022;  Published: 03 August 2022;  doi: 10.21926/obm.icm.2203031

Abstract

The current recommendations of the Canadian Paediatric Society about monitoring children’s disruptive behaviors at well-child visits call for screening if behavioral concerns are being raised by parents. But do parents’ concerns about their child’s behavior constitute a reliable means for primary care providers (PCPs) to decide either in favor or against screening? We conducted a rapid systematic review of the literature by identifying documents that cited the landmark study by Glascoe and her col [...]
