Reduction of the harmful NO pollutants emitted from the ship engines using high-pressure selective catalytic reduction system.

Various techniques are used to reduce harmful pollutants such as NO emissions from ships. Selective catalyst reduction (SCR) systems are the most effective technique used to reduce NO emissions. In this study, the effects of an SCR reactor on NO emissions and performance in high-pressure selective catalytic reduction (HP-SCR) systems were investigated numerically.

The Effect of Nonstress Device Noise Level on Stress Parameters in Primigravid Women: A Randomized Controlled Trial.

Introduction: This study evaluated the effect of the noise level of the nonstress test (NST) device on stress parameters in primigravid women.

Methods: A total of 44 pregnant women participated in a randomized clinical trial between February and October, 2021. The participants were divided randomly into 4 equal groups using an automated web-based randomization system and ensuring allocation concealment: the control group (NST device volume turned off), intervention group I (1-35 dB(A)), intervention group II (36-60 dB(A)), and intervention group III (61 dB(A) and above).

The effect of training about environmental toxicant Bisphenol-A exposure in pregnancy on maternal urine Bisphenol-A level.

Purpose: Bisphenol A (BPA) is an environmental toxin, clearly capable of initiating epigenetic modifications, leading to the development of numerous human illnesses such as metabolic, reproductive, and behavioural abnormalities. It also causes oxidative stress, which has been shown to be alleviated by selenium supplementation. The purpose of this study was to determine the effect of training of BPA exposure during pregnancy on urine BPA levels.

Treatment of Intracranial Aneurysms with the Pipeline Embolization Device Only: a Single Center Experience.

Purpose: The aim of this study was to evaluate the technical feasibility and rate of mid-term occlusion in aneurysms treated solely with the Pipeline Embolization Device (PED) in a German tertiary care university hospital.

Materials And Methods: Forty-nine non-consecutive intracranial aneurysms underwent endovascular treatment using the PED exclusively between March 2011 and May 2017 at our institution. Primary endpoint was a favorable aneurysm occlusion defined as OKM C1-3 and D (O'Kelly Marotta Scale).

Pretzel knot compared with standard suture knots.

Purpose: Aim of this paper is to compare the biomechanical properties of the Pretzel knot with the selected arthroscopic knots and to test the mechanical safety of this knot. The hypothesis was that the Pretzel knot may have equal or better mechanical properties than the arthroscopic knots tested in this study.

Methods: SMC, Giant, Dines, Nicky's, Tennessee Slider knots were chosen for comparison.

Effect of partial medial meniscectomy on the proprioceptive function of the knee.

Introduction: The aim of this study was to assess the proprioception of the partial meniscectomized knee and to assess if there is an effect on the knee proprioception.

Materials And Methods: We performed a case-control study involving patients with meniscus tear at the posterior horn of medial meniscus. Group 1 composed of 19 patients, with an average age of 26.

Dislocation of os trigonum presenting as a loose body in the ankle.

Unlabelled: Dislocation of the os trigonum presenting as a loose body is a rare clinical entity. In this report, we describe the case of a 34-year-old male who presented with symptoms of acute left ankle pain that was aggravated by motion and weight bearing. He also displayed lateral collateral ligamentous laxity, without the presence of an effusion.

[Approach to cartilage lesions and algorithm for treatment].

Cartilage symptoms in the knee may be encountered in various forms in orthopedic practice. The first stage from history to treatment is to establish the diagnosis; if the diagnosis is made as a cartilage lesion in the knee, priority must be given to current treatment approaches. The surgeon must provide information regarding etiology, defect thickness, lesion size, the containment of cartilage, localization, stability, meniscal integrity, anatomic alignment of the knee, previous assessments, radiological assessment (direct radiography, magnetic resonance imaging), and general, medical, and systemic conditions, and family history.
