Published: June 2022

Celiac disease (CD) is a systemic immune-mediated disorder characterized by a specific serological and histological profile triggered by gluten ingestion, which is given in genetically predisposed subjects. Heterogeneous clinical presentation is characteristic in CD, affecting any organ or tissue with gastrointestinal, extraintestinal, seronegative, or nonresponsive manifestations. CD diagnosis is based on several criteria, including genetic and serological tests, clinical symptoms and/or risk conditions, and duodenal biopsy. Currently, the available treatment for CD is a strict gluten-free diet (GFD) that essentially relies on the consumption of naturally gluten-free foods, such as animal-based products, fruits, vegetables, legumes, and nuts, as well as gluten-free dietary products that may not contain more than 20 mg of gluten per kg of food according to Codex Alimentarius. However, it is difficult to maintain a strict oral diet for life and at least one-third of patients with CD are exposed to gluten. Difficulties adhering to a GFD have led to new tools to monitor the correct adherence to GFD and alternative forms of treatment.

Authors: Al-Lahham Adnan 
Published: June 2022

Pneumococcal carriage is a prerequisite for invasive and non-invasive infections, where children and elderly are the most vulnerable groups. Aims: Determine rates of carriage, resistance, and coverage of the pneumococcal conjugate vaccines (PCVs) in children attending day care centers (DCC) in north Jordan. Methods: Nasopharyngeal swabs (NP) were taken from healthy Jordanian children from north Jordan with ages ranging from 1 month to 14 years in the period from 2008 to 2019. Classical methods were used for cultivation, identification, resistance testing, and serotyping. Results: 1866 NP swabs were tested with carriage rate 39.3% (733 isolates). Resistance was variable; however, it showed highest rates for penicillin (89.3%) and trimethoprim-sulfamethoxazole (73.0%). Serotype 19F predominates with 17.6% of all serotypes. Coverage of the future PCV20 was 73.1% compared to the old PCV7 (41.7%). About 493 cases had a previous 1–3 PCV7 injections, among which 256 (51.9%) cases were pneumococcal carriers, distributed as non-PCV vaccine serotypes (31.6%), and with PCV types (68.4%). Conclusions: The potential inclusion of the PCV vaccination in the national immunization program of the country is necessary.
Assessment of Station Keeping Capability for Dynamically Positioned Offshore Supply Vessel
Authors: Elkafas Ahmed G. 
Published: June 2022

Abstract
Dynamic positioning capability (DPCap) assessment is essential during the preliminary investigation of the positioning ability of a newly designed dynamic positioning system (DPS). Operational safety is always the first consideration in the design and operation of a new DPS. To be able to plan a safe and efficient operation, it is important to know the maximum environmental conditions that the DP vessel can withstand. The main objective of this article is to present a developed tool capable of conducting the DPCap analysis for offshore supply vessels based on the DNVGL methodology. The article describes the background studies, methodology, and mechanism associated with the formulation and development of the tool. The optimization of the design variables for the station-keeping criteria targets the highest capability at the lowest possible energy expenditure. Finally, the results are presented in the form of standard capability polar plots to show the application of the computational assessment procedure. The accuracy and reliability of the DPCap tool are validated by comparing with the results of the commercial one for the same case study ship at multiple simulation cases.

Introduction
Many offshore operations require the vessel to be kept in a position to face environmental loads from wind, waves and current. This can be achieved using Dynamic Positioning System (DPS) by using thrusters (Sørensen 2011).
Station keeping ability is used in different types of vessels with varying operational requirements. Cruise vessels and mega yachts use it in the form of virtual anchoring to avoid the environmental impact of anchoring in the sensitive estuaries they often ply. The importance of DPS is growing because of the increase in the number of offshore construction sites requiring DPS for their operations (Mehrzadi et al. 2020). Over the last four decades, dynamic positioning (DP) in deep water has been used in the marine sector, oil and gas industries, and military services in many tasks such as drilling, oil and gas floating production platform, cable, and pipe laying, docking and towing, firefighting, supply, search and rescue, surveying, and mobile offshore bases (MOB). Each of these operations benefits from a DP system’s ability to include precise position-keeping, freedom from the restrictions of mooring spread systems, the ability to move quickly from one site to another, and track-keeping capabilities (Elkafas et al. 2021; Mahfouz 2007).

The herbaceous perennial legume Mimosa pudica is an invasive weed in many tropical and subtropical regions and a serious problem for farmers since it is difficult to eliminate from crop field by hand. Moreover, it has water impermeable seeds, i.e., physical dormancy (PY), which could persist in the soil seed bank for a long period of time, thus making it a big challenge to control. The aims of this study were to test the effect of various laboratory methods on breaking PY in seeds of M. pudica, to identify the site(s) of water entry into seeds of M. pudica and compare results of dormancy-breaking methods for seeds of M. pudica with those of 36 other species of Mimosa reported in the literature. Mechanical scarification, wet heat and cycles of wet heat and ice water effectively broke PY in seeds of M. pudica. Following wet heat at 80 °C for 10 min, water uptake was via the hilar region but not the pleurogram; small cracks made in the pleurogram by this treatment were not deep enough for water to enter the seed. Neither tolerance to summer temperatures nor PY is likely to be the cause of invasiveness of this species, since seeds of rare and endemic species of Mimosa also tolerate summer temperatures and have PY.

This study is intended to explore the protective effects of resveratrol (RES) on iron overload-induced liver fibrosis and its mechanism. Iron dextran (50 mg/kg) was injected intraperitoneally in all groups except the control group. Mice in the L-RES, M-RES and H-RES groups were gavaged with RES solution at 25, 50 mg/kg and 100 mg/kg, respectively, 4 h before injection of iron dextran every day; mice in the deferoxamine (DFO) group were injected with DFO intraperitoneally (100 mg/kg); mice in the control group received isovolumetric saline. After seven weeks of RES administration, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) activities and liver hydroxyproline (Hyp) levels were reduced; the malondialdehyde (MDA) activities decreased and the levels of superoxide dismutase (SOD) and glutathione (GSH) were raised. Hematoxylin and eosin (H&E), Prussian, and Masson staining indicated that RES treatment could improve cell damage and reduce hepatic iron deposition and collagen deposition in iron-overload mice. The expression of Bcl-2 was increased, the expression levels of Bax and caspase-3 were decreased under RES treatment. Moreover, RES reduced the expression of hepcidin, ferritin (Ft), divalent metal transporter-1 (DMT-1), transferrin receptor-2 (TFR-2), and raised the expression of ferroprotein-1 (FPN-1). In conclusion, RES could ameliorate iron overload-induced liver fibrosis, and the potential mechanisms may be related to antioxidant, anti-inflammatory, anti-apoptotic, and more importantly, regulation of iron homeostasis by reducing iron uptake and increasing iron export.

Published: June 2022

Back Ground: Baby corn maize (Zea mays L.) is a highly profitable alternative to farmers due to its short crop duration, being harvested at the juvenile stage. It demands large amounts of nutrients in a short time. Iron micronutrients gives higher yield as they play major role in assimilation rate and metabolic activities in plant. Biofertilizers are required to restore the fertility of the soil. Prolonged use of chemical fertilizers degrades the soil and affects baby corn yield.
Objectives: Effect of iron and bio-fertilizers on growth and yield of baby corn.
Methods: With the goal of studying the effect of iron and bio-fertilizers on growth and yield of Baby corn (Zea mays L.) Var. ABV - 04 under a Randomized block design with 8 treatments (T1-T8).The experimental results revealed that 0.5% FeSO4 (3g/lit of water) + Azotobacter seed inoculation (200 g/10kg of seed) produced maximum plant height (185.27), number of leaves/plant(12.58),plant dry weight (89.28) and yield parameters cobs/plant (2.34), cob weight without husk (12.34g), cob yield with husk(10.81 t/ha), and cob yield without husk(3.91t/ha).
Conclusion: Based on the findings of this study, it is concluded that 0.5 percent FeSO4 (5g/lit of water) + Azotobacter seed inoculation (200 g/10kg of seed) can ensure the profitable production of baby corn. These practises could be passed on to farmers to help them earn more money in this agro-climatic zone.

Time‐varying nonsingular terminal sliding mode control for uncertain second‐order nonlinear systems with prespecified time
Authors: Boukattaya Mohamed , Gassara Hamdi 
Published: June 2022

AbstractThis article proposes a time‐varying nonsingular terminal sliding mode (TSM) control for a class of uncertain second‐order nonlinear system and its application to n‐links rigid robotic manipulators. First, a time‐varying nonsingular terminal sliding manifold is developed by incorporating a piecewise‐defined function of time into a nonsingular TSM manifold. As a result, the singularity problem is avoided and the reaching phase existing in conventional TSM control is totally suppressed which ensures the global robustness of the system against uncertainties and disturbances. Moreover, adaptive tuning laws are developed to omit the requirement of prior knowledge of the upper bound of the lumped uncertainty. In particular, an effective method is provided for the parameters selection to meet a prespecified convergence time. Hence, the convergence time to the origin of the tracking errors can be specified in advance according to the mission requirements. The formulation of the controllers and the stability analysis are verified by Lyapunov theory. Simulation results and comparative studies are presented to demonstrate the effectiveness and the superiority of the proposed algorithms.

Published: June 2022

AbstractAtherothrombosis, an atherosclerotic plaque disruption condition with superimposed thrombosis, is the underlying cause of cardiovascular episodes. Herein, a unique design is presented to develop a microfluidic site‐specific atherothrombosis‐on‐chip model, providing a universal platform for studying the crosstalk between blood cells and plaque components. The device consists of two interconnected microchannels, namely main and supporting channels: the former mimics the vessel geometry with different stenosis, and the latter introduces plaque components to the circulation simultaneously. The unique design allows the site‐specific introduction of plaque components in stenosed channels ranging from 0% to above 50%, resulting in thrombosis, which has not been achieved previously. The device successfully explains the correlation between vessel geometry and thrombus formation phenomenon as well as the influence of shear rate on platelet aggregation, confirming the reliability and the effectiveness of the design. The device exhibits significant sensitivity to aspirin. In therapeutic doses (50 × 10−6 and 100 × 10−6 m), aspirin delays and prevents platelet adhesion, thereby reducing the thrombus area in a dose‐dependent manner. Finally, the device is effectively employed in testing the targeted binding of the RGD (arginyl‐glycyl‐aspartic acid) labeled polymeric nanoparticles on the thrombus, extending the use of the device to examine targeted drug carriers.

AbstractSolar‐driven interfacial evaporation materials for seawater desalination and wastewater treatment have attracted extensive research interest in recent years. Nevertheless, salt accumulation, costly materials, and complex preparation processes greatly hinder the practical application of solar steam generation. Herein, with low‐cost materials such as carbon black (CB), polystyrene‐b‐polybutadiene‐b‐polystyrene (SBS), and commercial cotton fabric, the CB@SBS/cotton fabric Janus evaporator is fabricated via a breath figure template (BFT) method for scalable, long‐term, and stable solar‐driven interfacial desalination. The BFT is a simple yet efficient self‐assembly method that endows the hydrophobic surface of CB@SBS/cotton fabric with a porous structure for high light absorption (≈95.5%) and steam escape. As a result, the CB@SBS/cotton fabric Janus evaporator can achieve a water evaporation rate of 1.37 kg m–2 h–1 and conversion efficiency of 91.3% even in a 3.5 wt% NaCl solution, as well as stably cycling over 15 times without salt accumulation (each cycle: 8 h for illumination and 16 h for rest). The work demonstrates an effective strategy for achieving high‐performance solar steam generation and superior salt rejection capability, which can be potentially utilized in seawater desalination, sterilization, and disinfection.
