pH-Dependent selective extraction of gold(iii) from synthetic solution and computer motherboard leachate using a hybrid nanocomposite.

Recycling gold from electronic waste offers significant benefits for both environmental protection and resource sustainability. However, this process presents considerable challenges due to high costs, prolonged processing times, and interference from coexisting metals. In this study, we synthesized a hybrid mesoporous nanocomposite comprising platelets-like CoNiS incorporated with g-CN nanosheets (CoNiS@g-CN) for the selective recovery of gold (Au(iii)) ions from spent computer motherboards.

Practical prototype for energy management system in smart microgrid considering uncertainties and energy theft.

The conventional electrical grid faces significant issues, which this paper aims to address one of most of them using a proposed prototype of a smart microgrid energy management system. In addition to relying too heavily on fossil fuels, electricity theft is another great issue. The proposed energy management system can simultaneously detect electricity theft and implement demand response tactics by employing time-of-use pricing principles and comparing real electricity consumption with grid data.

Is music intervention effective in reducing anxiety and pain during breast biopsy procedure? A systematic review and meta-analysis of randomized controlled trials.

Purpose: To evaluate the evidence from randomized clinical trials (RCTs) about the effect of music intervention in reducing patients' anxiety during breast biopsy.

Methods: Electronic databases including PubMed, Cochrane Library, Scopus, and Web of Science were searched using the relevant MeSH terms. The inclusion criteria were all RCTs assessing the effect of music therapy versus no music in reducing anxiety during breast biopsy.

Utilization of the track embolization technique to improve the safety of percutaneous lung biopsy and/or fiducial marker placement.

Purpose: The purpose of the study was to describe and present outcomes of the track embolization technique with absorbable hemostat gelatin powder during percutaneous computed tomography (CT)-guided lung biopsy and/or fiducial marker placement versus the standard of care (no track embolization) in an attempt to decrease rates of pneumothorax (PTX), chest tube placement, hemorrhage and/or complications, and average cost per patient.

Materials And Methods: An institutional review board-approved, case-control, retrospective study was performed in which 125 consecutive patients who underwent track embolization were compared with 124 consecutive controls at one institution. For subjects in whom the track embolization technique was utilized, it was performed passively through a coaxial needle as it was removed.

Combating the Health Risks of Sedentary Behavior in the Contemporary Radiology Reading Room.

Objective: We detail the association of sedentary behavior with a variety of health problems and provide the radiologist with a number of simple activities and techniques that can improve overall health while still meeting the productivity demands of a high-volume practice. Although these techniques are well known and recognized in the fitness and nutrition literature, they are not widely used in the radiology reading room. The computer- and workstation-based work routinely performed by diagnostic radiologists typically occurs in the seated position, leading to more than 8 hours per day of sitting.

The volumetric analysis of fat graft survival in breast reconstruction.

Background: Fat grafting has emerged as a useful method for breast contouring in aesthetic and reconstructive patients. Advancements have been made in fat graft harvest and delivery, but the ability to judge the overall success of fat grafting remains limited. The authors applied three-dimensional imaging technology to assess volumetric fat graft survival following autologous fat transfer to the breast.

Defining pseudoptosis (bottoming out) 3 years after short-scar medial pedicle breast reduction.

Background: Pseudoptosis (bottoming out) is a well-observed phenomenon occurring after all types of breast reduction surgery. The authors' team previously reported the use of three-dimensional (3D) imaging to demonstrate that significant morphologic changes occur in the breast during the first year after short-scar medial pedicle breast reduction. This study extended this evaluation to postoperative year 3.

Metered-dose inhaler efficiency enhancement: a case study and novel design.

The efficiency of the metered-dose inhaler (MDI) is a critical issue in aerosol medicine because it deals with delivering a life-saving medication to patients with various lung diseases. Mouthpiece diameter, air flow rate, and entrance angle are among many parameters that influence the MDI penetration efficiency. It is well known that inertial impaction accounts for the massive aerosol deposition in the oral airway.

Balloon-based in vitro MDI aerosol deposition experiments on the effects of mouthpiece diameter.

For this article, we studied the effects of mouthpiece diameter and flow rate on aerosol penetration efficiency for metered-dose inhaler (MDI) applications. Measurements show that increasing the mouthpiece diameter has a moderate and positive influence on the particle penetration efficiency of the MDI. The particle penetration efficiency increases monotonically with the increase of the mouthpiece diameter from 16 mm to 20 mm.
