Construction & Demolition Waste and Circular Economy: The Case Study of a Brazilian City

Received: 11 August 2024;  Published: 24 December 2024;  doi: 10.21926/rpm.2404029

Abstract

Construction and demolition waste (CDW) is a significant waste stream in Brazil. It represents 38.2% of the total CDW and MSW streams. The recycling of CDW in Brazil is estimated to be at least 7.2% by weight (collected CDW) or about 15% by volume (produced CDW). Therefore, only a tiny part of CDW is returned to construction activities. On the other hand, 48.9% of the total amount of the top fifty extracted minerals in the country is sand and gravel, which is used in the national construction industry. Considering [...]

The Rational Use of Diuretics in the Management of Cirrhotic Ascites in Japan

Received: 04 February 2019;  Published: 25 April 2019;  doi: 10.21926/obm.hg.1902018

Abstract

In cirrhosis, portal hypertension and hypoalbuminemia due to decreased albumin synthetic capacity and hormonal imbalance due to increased renin-angiotensin-aldosterone and vasopressin systems cause fluid retention and electrolyte abnormalities. Diuretics are indispensable for the control of body fluid volume in liver cirrhosis, and aldosterone antagonists and loop diuretics have been widely used until now. In Japan, tolvaptan, a vasopressin V2 receptor antagonists, became available in September 2013, expanding trea [...]

Mechanics of ABS Polymer under Low & Intermediate Strain Rates

Received: 24 January 2023;  Published: 16 March 2023;  doi: 10.21926/rpm.2301012

Abstract

Thermoplastics polymers like Acrylonitrile Butadiene Styrene (ABS) are often reinforced with nano/micro reinforcements to enhance their mechanical, thermal and electrical properties. However, the viscoelastic nature of these polymers results in their strong dependence on the applied strain rate and temperature sensitivity, leading to their characterization complexity. Hence it is paramount to study the strain rate-dependent mechanics of neat ABS. In this study, the effect of strain rate and temperature on Young’s m [...]

The Tension Between Growth and Innovation Led Greenhouse Gas Reductions in the Information and Communication Technology and Media and Entertainment Sector: A Case Study of AT&T Inc.

Received: 13 January 2022;  Published: 15 April 2022;  doi: 10.21926/aeer.2202013

Abstract

With scientific consensus on climate change and growing public concern, firms are recognising the multiple risks associated with inaction on their Greenhouse Gas (GHG) emissions. The Information and Communications Technology (ICT) and Entertainment & Media (E&M) sectors provide essential communications services, that are foundational for much of the modern world's social and economic systems. The ICT sector has already demonstrated success in innovations that enable emissions reductions. At the same tim [...]

Ni-Silica-based Catalysts for CH4 Reforming by CO2 with Enhanced Stability: Recent Designs and the Impacts of Ni Confinement, Promoters, and Core-Shell Structures

Received: 01 September 2020;  Published: 26 January 2021;  doi: 10.21926/jept.2101007

Abstract

CO2 reforming of CH4, also referred to as the Dry Reforming of Methane (DRM), is considered an excellent method to produce H2 and CO (syngas), which are known to be used for the production of higher alkanes and oxygenates. Despite nickel’s moderate toxicity, Ni-based heterogeneous catalysts are considered excellent candidates for use in DRM due to their reasonable performances and economic advantages. However, these materials also present severe drawbacks, such as sintering of the active phase and coke (carbo [...]

Assessing the Factor Structure and Construct Validity of the Beck Depression Inventory (BDI-II) in a Korean Preschool Teacher Sample

Received: 07 March 2024;  Published: 21 May 2024;  doi: 10.21926/obm.neurobiol.2402224

Abstract

Preschool teachers are at high risk of depression. Therefore, emphasis should be placed on evaluating a valid and reliable instrument to measure depressive symptomatology for this population. One such promising instrument is the Beck Depression Inventory (BDI-II), a 21-item self-report measure designed to assess the presence and severity of depression. Although the tool’s psychometric properties have been analyzed in different samples, they have not been validated with a Korean preschool teacher sample. Hence, this [...]

Traditional, Complementary and Integrative Medicine Approaches to COVID-19: A Narrative Review

Received: 11 April 2021;  Published: 12 July 2021;  doi: 10.21926/obm.icm.2103021

Abstract

Traditional, complementary, and integrative medicine (TCIM) approaches to COVID-19 represent a paradigm shift from Western medicine, in that TCIM emphasizes prevention, encouraging wellness, and supporting health and recovery. A wide range of TCIM approaches exist: whole medical systems (such as traditional Chinese medicine), mind-body approaches, biological therapies, body-based treatments, and energy therapies. TCIM is used to help people resist infection, but people with moderate to severe COVID-19 symptoms ofte [...]

Dopaminergic Activity and Exercise Behavior in Anorexia Nervosa

Received: 03 December 2019;  Published: 23 March 2020;  doi: 10.21926/obm.neurobiol.2001053

Abstract

Driven exercise (i.e., the tendency to exercise in excess to influence weight/shape or regulate emotion) is difficult to manage in the context of anorexia nervosa, and is associated with poorer treatment outcomes, and psychological and medical severity. Driven exercise is observed in a considerable number of those diagnosed with anorexia nervosa; however, to date, this hallmark symptom remains poorly understood. Dopamine signaling is implicated in motivating and maintaining appetitive behavior among patients with e [...]

Prone Anesthesia for a Super-Super Morbidly Obese Patient Undergoing Neurosurgery: A Case Report

Received: 03 May 2020;  Published: 24 June 2020;  doi: 10.21926/obm.neurobiol.2002064

Abstract

Obesity is on the rise around the world, carrying along with it a wide range of comorbidities and complications. We report on a super-super morbidly obese 43-year-old female, with a body mass index (BMI) of 77.85 kg/m2 (173cm, 233kg), who presented for a scheduled suboccipital craniectomy with C-1 laminectomy secondary to symptoms from an Arnold-Chiari type-I malformation. Already a challenging type of surgery, due to the patient’s extreme BMI and positioning, the surgery became more difficult. There are many [...]

Self-Hypnosis for Phantom Limb Pain: A Multiple-Case Study

Received: 29 June 2022;  Published: 09 September 2022;  doi: 10.21926/obm.icm.2203040

Abstract

Phantom limb pain occurs in more than half of the people who have undergone an amputation. Hypnosis can alleviate pain effectively in experimental, procedural, and chronic pain. Thus, in this multiple-case study, we determined whether hypnosis might be a successful complementary approach to help patients with phantom limb pain in alleviating their pain quality (i.e., sensitive and affective), intensity, fatigue, and emotional distress (i.e., anxiety and depression). Seven patients experiencing phantom limb pain wer [...]
