Natural Fibres as a Sustainable Reinforcement Constituent in Aligned Discontinuous Polymer Composites Produced by the HiPerDiF Method.

Sustainable fibre reinforced polymer composites have drawn significant attention in many industrial sectors as a means for overcoming issues with end-of-life regulations and other environmental concerns. Plant based natural fibres are considered to be the most suitable reinforcement for sustainable composites since they are typically from renewable resources, are cheap, and are biodegradable. In this study, a number of plant based natural fibres-curaua, flax, and jute fibres-are used to reinforce epoxy, poly(lactic acid) (PLA), and polypropylene (PP) matrices to form aligned discontinuous natural fibre reinforced composites (ADNFRC).

The comparative performance of DBS artefact rejection methods for MEG recordings.

Deep brain stimulation (DBS) can be a very efficient treatment option for movement disorders and psychiatric diseases. To better understand DBS mechanisms, brain activity can be recorded using magnetoencephalography (MEG) with the stimulator turned on. However, DBS produces large artefacts compromising MEG data quality due to both the applied current and the movement of wires connecting the stimulator with the electrode.

Characterisation of Natural Fibres for Sustainable Discontinuous Fibre Composite Materials.

Growing environmental concerns and stringent waste-flow regulations make the development of sustainable composites a current industrial necessity. Natural fibre reinforcements are derived from renewable resources and are both cheap and biodegradable. When they are produced using eco-friendly, low hazard processes, then they can be considered as a sustainable source of fibrous reinforcement.

Treatment of fragmented and severely encrusted ureteral double-J stent forgotten for 11 years through multimodal endourological methods.

Ureteral catheters are frequently used in urology clinics for intrinsic or extrinsic pathologies which cause ureteral obstruction to provide urinary drainage from the kidney to the bladder. With the increase in stent use, an increase is observed in complications occurring due to ureteral stents in direct proportion with this increase, and ureteral double-J (DJ) stents forgotten in the urinary system are observed commonly in urological cases when the patients do not refer to a health institution in this condition and may cause severe problems, such as infection, stent fragmentation, migration, kidney failure, encrustation, and hydronephrosis conditions. A 30-year-old male patient referred to our clinic with right-side pain, dysuria, and incontinence complaints.

Significance of red blood cell distribution width and C-reactive protein/albumin levels in predicting prognosis of acute pancreatitis.

Background: Acute pancreatitis (AP) is one of the major pathologies among gastrointestinal system diseases. The aim of this study was to determine the relationship between the red cell distribution width (RDW) value and the C-reactive protein (CRP)/ albumin ratio in patients with AP.

Methods: In this retrospective study, AP cases were enrolled and divided into 2 groups according to the Ranson criteria as moderate or severe pancreatitis.

Therapeutic plasma exchange for hypertriglyceridemia induced acut pancreatitis: the 33 cases experience from a tertiary reference center in Turkey.

Background/aims: Hypertriglyceridemia (HTG) is the third most common cause of acute pancreatitis. In patients with severe HTG (TG level>1000 mg/dL), it may be beneficial to immediately lower the levels of triglyceride (TG) and chylomicrons. In this study, we present one of the largest case series on the use of therapeutic plasma exchange (TPE) for hypertriglyceridemia-induced acute pancreatitis (HTG-AP).

Rare cause of duodenal obstruction: Bouveret syndrome.

Gallstone ileus is a relatively rare pathology, most commonly obstructing the terminal ileum. Bouveret syndrome is a syndrome found particularly in elderly patients, which develops as the result of a cholecystoenteric fistula. It leads to the gastric outlet obstruction and has an incidence of less than 1%.

Monitoring the effect of asymmetrical vertical strain on Janus single layers of MoSSe via vibrational spectrum.

Using first principles calculations, we study the structural and phononic properties of the recently synthesized Janus type single layers of molybdenum dichalcogenides. The Janus MoSSe single layer possesses 2H crystal structure with two different chalcogenide sides that lead to out-of-plane anisotropy. By virtue of the asymmetric structure of the ultra-thin Janus type crystal, we induced the out-of-plane anisotropy to show the distinctive vertical pressure effect on the vibrational properties of the Janus material.

Monolayer AsTe : Stable Robust Metal in 2D, 1D and 0D.

The structural, phononic, and electronic properties of the monolayer structures of AsTe are characterized by performing density functional theory (DFT) calculations. Total energy optimization and phonon calculations reveal that single layers of the 2H-AsTe and 1T-AsTe phases form dynamically stable crystal structures. Electronic structure analysis also shows that both 2H and 1T phases have nonmagnetic metallic character.

Bilayers of Janus WSSe: monitoring the stacking type via the vibrational spectrum.

Motivated by the recent successful synthesis of Janus type single layers of transition metal dichalcogenides, we investigate the stability, vibrational and electronic properties of the Janus single layer structure of WSSe and its bilayers by means of density functional theory. The structural and vibrational analysis show that the Janus single layer of WSSe forms a dynamically stable structure in the 2H phase. Owing to its non-centrosymmetric structure, the Janus WSSe single layer has two in-plane (E) and two out-of-plane (A) Raman active phonon modes.

Clinical usefulness of psoas muscle thickness for the diagnosis of sarcopenia in patients with liver cirrhosis.

The aim of this study was to evaluate the optimal cutoff values of PMTH for detecting sarcopenia in cirrhotic patients.

Fracture With Urethral Injury: Evaluation by Retrograde Urethrogram.

Penile fracture is a rare condition. It primarily involves the rupture of the corpus cavernosum during erection, which may also affect the corpus spongiosum and urethra. We describe the case of a 35-year-old man who presented with acute penile pain, penile swelling, and a hematuria after a blunt trauma during sexual intercourse.

Hydrogenation-driven phase transition in single-layer TiSe.

First-principles calculations based on density-functional theory are used to investigate the effects of hydrogenation on the structural, vibrational, thermal and electronic properties of the charge density wave (CDW) phase of single-layer TiSe. It is found that hydrogenation of single-layer TiSe is possible through adsorption of a H atom on each Se site. Our total energy and phonon calculations reveal that a structural phase transition occurs from the CDW phase to the T phase upon full hydrogenation.
