Recent advances in high-power applications employing voltage source converters have been primarily fuelled by the emergence of the modular multilevel converter (MMC) and its derivatives. Model predictive control (MPC) has emerged as an effective way of controlling these converters because of its high response. However, the practical implementation of MPC encounters hurdles, particularly in MMCs featuring many sub-modules per arm. This research introduces an approach termed folding model predictive control (FMPC), coupled with a pre-processing sorting algorithm, tailored for modular multilevel converters. The objective is to alleviate a significant part of the computational burden associated with the control of these converters. The FMPC framework combines multiple control objectives, encompassing AC current, DC current, circulating current, arm energy, and leg energy, within a unified cost function. Both simulation studies and real-time hardware-in-the-loop (HIL) testing are conducted to verify the efficacy of the proposed FMPC. The findings underscore the FMPC's ability to deliver fast response and robust performance under both steady-state and dynamic operating conditions. Moreover, the FMPC adeptly mitigates circulating currents, reduces total harmonic distortion (THD%), and upholds capacitor voltage stability within acceptable thresholds, even in the presence of harmonic distortions in the AC grid. The practical applicability of MMCs, notwithstanding the presence of a large number of sub-modules (SMs) per arm, is facilitated by the significant reduction in switching states and computational overhead achieved through the FMPC approach.

Titanium (Ti) and its alloys are frequently employed in the biomedical industry because they have a high corrosion resistance in addition to being lightweight, non-toxic, and having excellent biocompatibility. In this work, the microstructure and some required properties were evaluated for binary Ti-15Zr alloy produced by powder metallurgy (PM) for biomedical applications; the obtained results were also compared to that of commercially pure Ti (CP-Ti). The major goal of this paper is to study the impact of Zr addition on the microstructure, microhardness, and corrosion resistance of Ti alloy. [ABSTRACT FROM AUTHOR]

This article explores the influence of micro factors, specifically liquidity and profitability indicators, on the performance of the Iraq Stock Exchange Index from 2005 to 2021. The study utilizes time series analysis and the ARDL methodology to investigate the relationship between these micro factors and the stock market return. The findings indicate that financial factors have a significant impact on the stock exchange index, with banking liquidity demonstrating a stronger correlation than banking profitability. The study underscores the importance of considering micro-financial factors when making decisions and predicting future economic volatility and risk management. [Extracted from the article]

Brucella is one of the pathogens that spread globally, these bacteria are transmitted by livestock and their products, and their infections are chronic infections due to the presence of many virulence factors of this bacteria that protect these bacteria from the body's defenses and immunity, and from this endotoxin (Lipopolysaccharide) as well as the secretion of various enzymes like Urease, Superoxide dismutase, and Catalase. Brucellosis leads to greater growth of lymph nodes, liver, and spleen. Brucella's pathogenicity relies on its capacity to replicate, live inside the macrophages and virulence factors.

The Internet of Things (IoT) is a newly emerging term for the new generation of the Internet which allows understanding between interconnected devices. IoT acts as an assistant in healthcare and plays an extremely important role in wide scopes of medicinal services observing applications. Through determining the pattern of parameters that are observed, the character of the disease can be expected. Health specialists and technicians have developed a great system with low-cost healthcare monitoring for people suffering from many diseases using common techniques such as wearable devices, wireless channels, and other remote devices. Network-related sensors, either worn on the body or in living environments, collect rich information to assess the physical and mental state of the patient. This work focuses on scanning the existing e-health (electronic healthcare) monitoring system using integrated systems. The main goal of the e-health monitoring system is to offer the patient a prescription automatically according to his or her condition. The doctor can check patient health continuously without physical interaction. The study aims to explore the uses of IoT applications in the medical sector, and its role in raising the level of medical care services in health institutions. Also, the study will address the applications of IoT in the medical field and the extent of its use to enrich traditional methods in various health fields and to determine the extent of the ability of IoT to improve the quality of health services provided. The study relies on a descriptive research approach through an analysis of the literature published in this field. The results of the study refer to the application of IoT in the health institutions, it will help to obtain accurate diagnoses for patients, which will reflect on the quality of service provided to the patient. It will also reduce periodic patient reviews to the hospital by relying on IoT applications for remote diagnosis. Also, an application in health institutions will contribute to providing data correct for the diseases that patients suffer from, and hence employing them in preparing scientific research to obtain more accurate results. This paper introduces the review of the Internet-based healthcare monitoring system (HCMS) and the general outlines on opportunities and challenges of the patient's Internet-based patient health monitoring system.

This research aimed to study effect of Clarithromycin drug on Cryptosporidium Parvum and efficiency of ELISA technique in diagnosis comparison with some traditional methods in vitro. Samples collected from four different sources water were 400 liters:100 liters tap water provider by Al-Kufa District River,100 liters house tank water,100 liters from sea of Al-Najaf and 100 liters stagnant water during period from October 2018 to April 2019.Examined samples by three laboratory methods: Modified Ziehl-Neelson stain, Flotation by saturated sugar solution method and ELISA to detecting from Cryptosporidium oocysts in the water as used Clarithromycin drug effective against C.parvum in vitro. Capability test was performed by impregnation of isolate on cell monolayers and determination the parasite counted after 48 h from the incubation at 37°C. Differ concentrations from Clarithromycin were 4, 8, 16 and 32 mg/L respectively compared with control group.

Inactivation or removal by chemical agents of microorganisms causing disease is called chemical disinfection. Includes viruses, bacteria and protozoans that are pathogenic micro-organisms causing disease. "alcohol" refers in the healthcare environment into two water soluble chemical compounds (ethyl alcohol and isopropyl alcohol) with general germicidal properties undervalued. Protein denaturation is the most plausible interpretation of alcohol's antimicrobial activity. The finding that absolute dehydrating ethyl alcohol is less bactericidal than alcoholic mixtures due to water assisted in this mechanism, when the proteins are denatured more rapidly in the event of water.
