Constantly examining novel alternative materials to improve devices performance is a pressing issue in light of the scaling constraints of siliconbased metal-oxide-semiconductor field-effect transistors (MOSFETs). Two-dimensional (2D) aluminum nitride (AlN) with constancy under ambient settings is a suitable channel material for the next MOSFET era. Using an ab-initio quantum-transport approach, the performance of n-type sub-5 nm devices built from a monolayer (ML) 2D AlN was studied. We found the double-gated (DG) ML AlN MOSFETs with an appropriate underlap region (UL) can meet the International Technology Roadmap for Semiconductors (ITRS) targets for 2028. Remarkably, the high-performance (HP) and low-power (LP) ML AlN MOSFET devices have high on-state currents (Ion) and perform up until gate lengths (Lg) of 2 and 3 nm, respectively. Additionally, ML AlN MOSFETs are competitive when compared to other 2D MOSFETs in terms of Ion, subthreshold swing (SS), delay time (†), and Power dissipation (PDP). Therefore, Moore's law could be stretched to a sub-5 nm range with AlN channel materials. [ABSTRACT FROM AUTHOR]

Vancomycin-resistant Enterococci(VRE) were common among Enterococcus. faecalis and Enterococcus faecium. Teicoplanin resistance or sensitivity can determine the VRE phenotypes whether VanA (VanR/TecR) or VanB (VanR/TecS). Linezolid resistance among VRE regards an newly emerged health problem. Infection with LRVRE or TRLRVRE pushan hazardous alert for hard to heal illness. Twenty eight Enterococcus spp. isolates were recovered from children diarrhea after their inoculation on m-EI chromogenic agar. Antibiotics susceptibility and phenotypic detection of antibiotics resistance were performed according to CLSI 2016. The results revealed 92.86% resistance to rifampin, 85.71% to erythromycin. VRE were 46.42%, TRE were 25% and LRE were 35.71% while co-existed resistance for Vancomycin/Teicoplanin/Linezolid(TRLRVRE) were detected 25% in. concern antibiotics resistant patterns, the MDR compile (85.7%) while XDR compile (10.7%) and there is no PDR among Enterococcus. spp. isolates were PDR. The presentstudy conclude that VanA and VanB phenotypes were common among MDR and XDR and although there is no using of linezolid but the emergence of TRLRVRE isolates were stated.

Abstract: As the capability of polar plots becomes better understood, improved dynamic positioning (DP) systems are possible since the control algorithms greatly depend on the accuracy of the aerodynamic and hydrodynamic models. The measurements and estimation of the environmental disturbances have an important role in the optimal design and selection of a DP system for a marine vessel. The main objective of this work is to present a new software program capable of estimating the environmental forces, thrusters capability calculations, and capability polar plots for marine vessels. A flowchart illustrating the logic and data flow of a developed software program, the Capability Polar Plot Program (CPPP), and the estimated results for two case studies for a scientific drilling vessel and a survey vessel are presented. It is obvious from the obtained results that the developed program has a future potential for the estimation of the Capability Polar Plots for marine vessels. Moreover, the developed software program would be considered as a marine tool for the thrusters'' selection and their configuration for marine vessels and floating production units for the Oil and Gas industries.

Background: Occurrence of acute oliguric renal failure in the immediate postoperative period carries important morbidity and mortality after a successful cardiac surgical procedure. Adult cardiac and aortic surgical procedures are especially prone to this complication with the incidence varying between 2% to 15% and the mortality rate as high as 40% to 60%. Aim of the Work: to compare between furosemide versus mannitol as a renal protection after adult cardiac surgery. Patients and Methods: This prospective comparative trial was conducted at Academy of Cardiothoracic Surgery Ain Shams University on patients undergoing CABG operation consisting of a total of 50 patients with normal renal function, EF of greater than 40%, normal protein and electrolyte levels. Results: the study revealed no statistically significant difference between groups according to cystatin-C. Conclusion: The difference between patients given mannitol and patients given furosemide regarding urinary microalbumin, urinary creatinine and serum cystatin-c was insignificant. Addition of mannitol to the priming solution of the cardiopulmonary bypass acts as a renal protector against AKI postoperative. Finally, giving furosemide infusion to patients undergoing cardiac surgery at the beginning of the CPB improves renal perfusion. [ABSTRACT FROM AUTHOR]

The root-knot nematode (RKN), Meloidogyne incognita, poses significant challenges for many important crops. Identified distinctive bacterial proteases have emerged as potential nematicides. In this study, the nprE from Bacillus subtilis 168 encoded the neutral metalloprotease, effectively enhancing it through a site-directed mutation. The enzyme-specific activity of pro118, secreted by the modified strain BS118, reached 215.4 U mg-1. It was twice that of pro168 produced by the wild-type strain BS168, which recorded an enzyme-specific activity of 101.6 U mg-1. The protease, pro118, caused the highest mortality in M. incognita juveniles, J2S (91.3% to 84.5%) after 48 h of in vitro treatment. Furthermore, when simultaneously applying pro118 with the nematode infection, it notably decreased the number of J2S, root galls, and egg masses/root systems by 19.5%, 18.8%, and 26.2%, respectively, compared with its application one week after the nematode infection. This consistent trend also manifested in the plant shoot length and fresh weight enrichment, which showed an increase of 9.7% and 14.7% in the first treatment versus the second. In conclusion, the study asserts that applying neutral metalloprotease as a bioagent to biocontrol M. incognita is a promising approach for mitigating the impact of this agricultural pest.

Background: Odontogenic sinusitis is an underdiagnosed entity and is one cause of failure of conventional treatments of sinusitis. Unfortunately, there is no consensus so far on the best management protocol. This retrospective study aimed to suggest a practical management protocol that can reduce misdiagnosis and improve treatment outcomes. Methods: The study included 74 patients with confirmed odontogenic sinusitis who were diagnosed and treated over 10 years (2010–2019). The patient data were recorded and analysed. Results: Dental pain was reported in only 31.1 per cent of patients. Fifty-six patients (75.7 per cent) had received dental treatment during the last year, but only 13 (23.1 per cent) reported it. Dental pathology was missed on initial computed tomography evaluation in 24 patients (32.4 per cent). Forty-one patients (55.4 per cent) were successfully treated by dental procedures and antibiotics. Fourteen patients needed functional endoscopic sinus surgery in addition to dental procedures. Conclusion: Successful management of odontogenic sinusitis requires good communication between rhinologists, radiologists and dentists. Dental treatment should be the logical first step in the treatment protocol, unless otherwise indicated. [ABSTRACT FROM AUTHOR]

In this work a laser shadowgraphy technique designed to test and enhance the automotive visual ergonomics is described. An experimental setup is used to test the field of view (FOV) of three sample cars through equiradial laser beam shadowgraphy from driver's cyclopean eye position. A resulting shadowgraph is analyzed to retrieve ergonomic drawbacks of each sample design. This technique help in the design of safer cars and also can be used to differentiate between several competitive cars from the same class whenever on ergonomic bases to lower collision probability due to bad designed driver's FOV. A complete modeling of experimental parameters is inclusive. [ABSTRACT FROM AUTHOR]

Background: Hyperhomocysteinemia is an independent risk factor for coronary, peripheral, and cerebrovascular disease. Elevated plasma homocysteine levels were described in a preliminary report on primary hypothyroidism.Objective: To determine whether restoration of euthyroidism by L-thyroxine replacement therapy would reduce or normalize plasma homocysteine levels.Design: Prospective cohort study.Setting: Outpatient endocrinology department of a tertiary center.Patients: 14 patients (10 women and 4 men; 25 to 77 years of age): 4 with newly diagnosed chronic (Hashimoto) hypothyroidism and 10 who had been rendered acutely hypothyroid (thyroid-stimulating hormone level > 25 mU/L) by total thyroidectomy for thyroid carcinoma.Measurements: Total plasma homocysteine levels were measured at baseline and 3 to 9 months later, after euthyroidism had been attained by L-thyroxine replacement therapy.Results: Median baseline plasma homocysteine levels in both sexes (women, 11.65 micromol/L [range, 7.2 to 26.5 micromol/L]; men, 15.1 micromol/L [range, 14.1 to 16.3 micromol/L]) were higher (P = 0.002) than those in healthy female (n = 35) and male (n = 36) volunteers (women, 7.52 micromol/L [range, 4.3 to 14.0 micromol/L]; men, 8.72 micromol/L [range, 5.94 to 14.98 micromol/L]). Eight patients (57%) had baseline plasma homocysteine levels that exceeded the upper limit of sex-specific reference ranges. Upon attainment of euthyroidism, all patients had a diminution in plasma homocysteine levels. The median overall change of -5.5 micromol/L (range, -15.4 to -1.8 micromol/L) corresponds to a difference of -44% (range, -58% to -13%) (P < 0.001). Homocysteine levels returned to normal in 7 of the 8 patients with elevated pretreatment values.Conclusions: Hypothyroidism may be a treatable cause of hyperhomocysteinemia, and elevated plasma homocysteine levels may be an independent risk factor for the accelerated atherosclerosis seen in primary hypothyroidism.

This article focuses on a study that explores effects of the gap-junction uncoupler carbenoxolone (CARB) on human myocardial conduction and arrhythmogenicity. All commercially available antiarrhythmic drugs modify action potential (AP) and are potentially pro-arrhythmic. CARB, an anti-ulcer drug, has been shown to reduce gap-junctional coupling without affecting cellular ion channels. The ability to terminate VT with pacing was effected by CARB in one patient due to slowing of conduction and apparent enlargement of the excitable gap.
