This paper presents a novel antenna design with an enhanced gain‐bandwidth product for modern communication networks, including 5G systems. The design is consistent with 17 unit cells of a composite right/left‐hand (CRLH) structure with an electromagnetic band gap of Hilbert inclusions. Therefore, the resulting design occupies an area of 40 × 200 mm2 of a Taconic RF‐43 substrate. The maximum antenna gain is 16 dBi at 5.5 GHz, which is very applicable for long‐range communication systems. Nevertheless, the antenna performance is controlled with optical switches of light‐dependent resistors (LDR) technology. Therefore, the antenna performance is tested with different switching seniors to investigate the possibility of reconfiguration scenarios at various frequency bands. However, the antenna gain is highly affected by changing LDR switching status; for example, at 5.5 GHz, the antenna gain is varied between 7 and 16 dBi. Thus, the proposed antenna is an excellent candidate for direct amplitude modulation. Finally, the antenna simulation results and measurements agree very well with each other. [ABSTRACT FROM AUTHOR]

Silicone and Glutathione application are including systemic acquired resistance or resistance induced against plant diseases against. It is a successful means to control plant rot disease and it leads to fundamental effects on the physiology of the host, as Silicone and Glutathione use in as induced resistance agent hostile to Fusarium solani causal agent of Broad bean root rot disease .The results of this study appeared that Silicone and Glutathione application have make less root tot incidence and severity in Broad bean plants and increase resistance-Linked enzymes Action of Peroxidase (POD) Polyphenol Oxidase (PPO) superoxide dismutase (SOD ) and Total Phenols (TP) in Broad bean infected roots with F. solani treated with Silicone and Glutathione. This indicates the ability of silicon and glutathione to induce resistance against fungus in bean plants by increasing the activity of polyphenol oxidase, peroxidase, and superoxide enzymes. These results are promising for the use of silicon and glutathione to control root rot infection of broad bean caused by F. solani. [ABSTRACT FROM AUTHOR]

Modern-day, global, and clever array systems have several distinguished approaches with regard to a wireless device. In this paper, a comparative analysis has been carried out amongst nine direction of arrival (DOA) algorithms: Capon, multiple signal classification (MUSIC), Bartlett, Pisarenko, linear prediction, maximum entropies, and min-norm, root- MUSIC, and estimation of signal parameters via rotational invariance technique (ESPRIT). in this paper reduces the number of antennas and snaps necessary to observe six target swithout interference for several DOA estimation methods. After comparing and analyzing all the algorithms, it has been shown that the music algorithm is the best algorithm that reduces interference and detects the desired sources. MATLAB R2019b was used in the simulation process. [ABSTRACT FROM AUTHOR]

During the last decade, attention was paid to detect the accident and call the ambulance as soon as possible, the situation was neglected after the arrival of the patient to the specified service point. This negligence led to an increase in the mortality rate, especially where the highest percentage of deaths occurred during the first hour after the accident. This highest Mortality can be avoided by providing proper health care after the arrival of the patient to the hospital, the proposed system reduces the rescue time after the arrival of a patient to the hospital, and it requires each hospital to be endowed with a reception model responsible for detecting and reporting accident situations to the emergency service. It was be found that there is an urgent need for a web-based hospital management system with a mobile web service to respond immediately to incidents in the event of an accident. This system utilizes the android phone application to connect to the server for transferring the specified data to the hospital and it can be used for comprehensive accident analysis and management. In this paper, a combination of Android phone application, database, and visual studio 2012 was used to develop the system. [ABSTRACT FROM AUTHOR]

Postnatal respiratory complications among term infants are common. The most commonly reported cause of neonatal respiratory distress is transient tachypnea of the newborn (TTN), with an estimated incidence of 0.5-2.8% of all newborns. Aim To evaluate and compare the efficacy and safety of inhaled salbutamol and intravenous (i.v.) furosemide in the treatment of TTN and to monitor of their possible adverse effects in neonates. Patients and methods This was a randomized controlled clinical trial on 100 neonates who were admitted immediately or shortly after birth owing to persistence of tachypnea to neonatal intensive care unit of pediatric hospitals, Cairo University, over a 1-year period. Our study included 100 neonates (25 in the salbutamol group, 25 in the furosemide group, and 50 in the control group) with TTN born between 35 and 39 weeks of gestational age. They were randomized in a blinded manner to receive one nebulized dose of salbutamol 0.15 mg/kg in 0.9% saline solution or i.v. furosemide 1 mg/kg once in addition to oxygen and i.v. fluids or received oxygen and i.v. fluids alone. Results The efficacy of inhaled salbutamol and furosemide was assessed by determining the respiratory rate, heart rate, TTN clinical score, and the level of respiratory support before receiving medication and 30 min, 1, and 4 h after drug therapy. The duration and level of respiratory support and the period of hospitalization were shorter in the salbutamol group. There was a significant decrease in the respiratory rate and TTN score in the salbutamol group 4 h after nebulized salbutamol. Conclusion Comparing the three groups after respiratory support, TTN score was significantly improved in the salbutamol group. The total duration of oxygen treatment in hours and total neonatal intensive care unit stay in days were significantly shorter in the salbutamol group than in furosemide and control groups. Regarding the safety of salbutamol, our study did not show a significant difference in adverse effects. Inhaled salbutamol treatment was effective in TTN without adverse events. Further studies at larger or repeated doses of furosemide may be needed. [ABSTRACT FROM AUTHOR]
