Vitiligo detection capabilities of 1D photonic crystal biosensing design.

This theoretical work focuses on the application of Tamm resonance-based biosensing using a one-dimensional photonic crystal for detecting skin vitiligo, a condition caused by the loss of pigment in the body. This biosensor utilizes the interaction of light with the photonic structure to identify the specific biomarkers associated with vitiligo. The proposed structure is composed of prism/Ag/skin-sample/(GaP/PS)/glass.

Towards renewable hydrogen-based electrolysis: Alkaline vs Proton Exchange Membrane.

This paper focuses on the battle for a dominant design for renewable hydrogen electrolysis in which the designs, alkaline and proton exchange membrane, compete for dominance. First, a literature review is performed to determine the most relevant factors that influence technology dominance. Following that, a Best Worst Method analysis is conducted by interviewing multiple industry experts.

Externally tunable multichannel filtering applications of organic material based 1D magnetic cold-plasma photonic crystals.

In the present research work, we employed the transfer matrix method (TMM) in addition to MATLAB software to examine the transmission properties of various organic-based one-dimensional (1D) magnetic cold-plasma photonic crystals (MCPPhCs). The proposed structures were found to be made up of periodic layers of organic materials and magnetic cold-plasma (MCP) at normal incidence. An external magnetic field (B) polarized in right-hand (RH) and left-hand (LH) configurations was applied on 1D MCPPhCs.

Study on a one-dimensional defective photonic crystal suitable for organic compound sensing applications.

Organic-compound-based sensors have important applications, such as applications in geothermal power stations, the shoe industry, the extraction of vegetable oil, azeotropic calibration and medical science. Herein, a 1D photonic crystal (PC) with a defect has been used to develop a photonic-technology-based organic compound sensor with optimum performance. The structure of the proposed organic compound sensor consists of a water cavity sandwiched between two symmetric sub-PCs, which are composed of alternate layers of SiO and ZnO.

Re-Learning EXP3 Multi-Armed Bandit Algorithm for Enhancing the Massive IoT-LoRaWAN Network Performance.

Long-Range Wide Area Network (LoRaWAN) is an open-source protocol for the standard Internet of Things (IoT) Low Power Wide Area Network (LPWAN). This work's focal point is the LoRa Multi-Armed Bandit decentralized decision-making solution. The contribution of this paper is to study the effect of the re-learning EXP3 Multi-Armed Bandit (MAB) algorithm with previous experts' advice on the LoRaWAN network performance.

Selective metal leaching from technosols based on synthetic root exudate composition.

This study focused on metal release from technosols induced by synthetic root exudate (SRE). The effect of SRE composition on metal release was studied using six technosols. This was done by treating the technosols with SRE solutions having varying concentrations of low molecular weight organic acids (LMWOAs), namely oxalic, citric, and malic acids.

The Application of Vacuum-Assisted Closure Device in the Management of Empyema Necessitans.

Vacuum-assisted closure (VAC) is gaining popularity in the management of many types of acute and chronic wounds. The use of VAC devices in thoracic surgery is limited, but it appears to be promising in complex cases of empyema thoraces. We report a case of empyema necessitans, in which VAC was used to achieve complete wound healing after open drainage which was communicating with the pleural space.

Influence of effluent organic matter on copper speciation and bioavailability in rivers under strong urban pressure.

This study focuses on spatiotemporal variations in the type of dissolved organic matter (DOM) and copper binding ability both upstream and downstream of Paris. It also compares the relative influence of both natural DOM upstream of Paris and effluent dissolved organic matter (EfDOM) output from a wastewater treatment plant (WWTP) on trace metal speciation and bioavailability in aquatic systems. In addition to the typical high- and low-affinity binding sites, a third family of very high-affinity binding sites has been highlighted for EfDOM.

Small bowel obstruction due to air-filled intragastric balloon.

Intragastric balloons have gained popularity in the management of morbid obesity. Although the procedure of insertion is easy and is generally accepted by patients, a few complications can occur. We report a case of small bowel obstruction caused by spontaneous deflation and forced passage of an air-filled intragastric balloon into the small bowel.

Laparoscopic adjustable gastric banding in a morbidly obese patient with situs inversus totalis.

Laparoscopic adjustable gastric banding is a commonly performed bariatric operation worldwide. The presence of an anatomical variation like situs inversus demands preoperative assessment and preparedness on the part of the surgeon. We report a laparoscopic gastric banding performed on a morbidly obese patient with situs inversus totalis in the Kingdom of Saudi Arabia.

Thyroid storm presenting as acute abdomen and normothermia.

Thyroid storm is a known complication of thyroid surgery. Nowadays, it is commonly seen in thyrotoxic patients. In this case report we discuss a patient who presented with acute abdomen and normothermia and was discovered to have thyrotoxicosis, a rare feature of thyroid storm.

Acute abdomen with pneumoperitoneum.

Acute appendicitis is a common cause of acute abdomen. However, it is a rare cause of pneumoperitonium. In this report the surgical diagnoses and management will be discussed in detail.
