The aircraft landing phase, marking the finishing of a flight plane, is a critical yet dangerous aerial maneuver. Even though it might seem simple, predicting the complexities of performance during landing presents a big challenge due to the dynamic characteristics of the phase, interaction with piloting methods, as well as inherent uncertainties in aerodynamics. Landing is executed in close proximity to the ground at reduced airspeed, the landing phase entails an escalated safety risk. Notably, incidents and accidents, particularly overruns where aircraft fail to slow sufficiently on the runway before landing, underscore the imperative for advanced landing technologies. This paper presents a comprehensive review of research spanning from 2000 to the present exploring smart techniques like fuzzy logic and machine learning, an array of control strategies ranging from classic PID control to sophisticated hybrid control approaches, and optimization procedures utilizing diverse optimization algorithms. The primary objective is to provide a comprehensive evaluation of the existing research landscape, offering insights that can propel the evolution of strategies for safer and more efficient landings and making sure the plane touches down safely.

Azapropazone (AZA) is anti-inflammatory drug for treatment of arthritic conditions with low side effect. The construction and electroanalytical uses of brand-new AZA voltammetric sensor are demonstrated. Working carbon paste electrodes integrated with 5.0% ZnONPs exhibited proper catalytic effect toward oxidation of AZA molecule. At pH 5.0, AZA recorded single irreversible anodic oxidation at 0.462 V. Based on CV registered at variable conditions, oxidation of AZA molecule by one proton and two electrons of N16 with de-localized lone pair of electrons. Calibration graphs showed good linearity within AZA concentration from 19.5 to 1040.75 ng mL−1 with LOD and LOQ values of 1.67 and 5.6 ng mL−1. The presented sensor showed improved LOQ and LOD values. Also, electrooxidation mechanism of AZA molecule and EIS of sensors were reported. The proposed analytical approach was examined for sensitive voltammetric determination of azapropazone in pharmaceutical formulations and biological fluids with agreeable recoveries.

Background: Several, clinical and biochemical factors were suggested as risk factors for more severe forms of Covid-19. Macrophage inflammatory protein-1 alpha (MIP-1α, CCL3) is a chemokine mainly involved in cell adhesion and migration. Intracellular adhesion molecule 1 (ICAM-1) is an inducible cell adhesion molecule involved in multiple immune processes. The present study aimed to assess the relationship between baseline serum MIP-1α and ICAM-1 level in critically-ill Covid-19 patients and the severity of computed tomography (CT) findings. Methods: The study included 100 consecutive critically-ill patients with Covid-19 infection. Diagnosis of infection was established on the basis of RT-PCR tests. Serum MIP-1α and ICAM-1 levels were assessed using commercially available ELISA kits. All patients were subjected to a high-resolution computed tomography assessment. Results: According to the computed tomography severity score, patients were classified into those with moderate/severe (n=49) and mild (n = 51) pulmonary involvement. Severe involvement was associated with significantly higher MIP-1α and ICAM-1 level. Correlation analysis identified significant positive correlations between MIP-1α and age, D-dimer, IL6, in contrast, there was an inverse correlation with INF-alpha. Additionally, ICAM-1 showed significant positive correlations with age, D‐Dimer,- TNF—α, IL6,while an inverse correlation with INF-alpha was observed. Conclusions: MIP-1α and ICAM-1 level are related to CT radiological severity in Covid-19 patients. Moreover, these markers are well-correlated with other inflammatory markers suggesting that they can be used as reliable prognostic markers in Covid-19 patients.

Background: Stress urinary incontinence is a frequent urological disease in women; it has a great influence on an individual’s wellbeing and places a significant economic strain on any health service. The placement of urodynamic diagnostic tests in the evaluation route is an important clinical research concern in this field. Objective: to find out whether the duration of stress urinary incontinence is associated with the finding of bladder outlet obstruction in urodynamic study or not. Subjects and Methods: A descriptive study. With enrolled female patients had symptomatic Stress urinary incontinence as their primary complain. All the included patients were assessed thoroughly by history taking and physical examination and relevant clinical tests and investigation in addition to urodynamic evaluation consisted of multi-channel urodynamics measuring abdominal, vesical and detrusor pressures simultaneously.

All patients with urethral pressure less than 120 cm had long duration mean than others but without statically significant (p=0.335). also, no statistical significance association between mean of duration and sphincter pelvic floor electromyogram (EMG). Conclusion: there was no catechistically significant relationship between the urodynamic findings and the duration neither of stress urinary incontinence nor between the urodynamic findings and the age of the patients.

The degradation and mineralization of 4-chlorophenol (4-CP) by advanced oxidation processes (AOPs) was investigated in this work, using both of UV/H2O2 and photo-Fenton UV/H2O2/Fe+3 systems.The reaction was influenced by the input concentration of H2O2, the amount of the iron catalyst, the type of iron salt, the pH and the concentration of 4-CP. A colored solution of benzoquinon can be observed through the first 5 minutes of irradiation time for UV/H2O2 system when low concentration (0.01mol/L) of H2O2 was used. The colored solution of benzoquinon could also be observed through the first 5 minutes for the UV/H2O2/Fe+3 system at high concentration (100ppm) of 4-CP. The results have shown that adding Fe+3 to the UV/H2O2 system enhanced the rate of 4-CP oxidation at a molar ratio of H2O2/Fe+3/4-CP equals to 13/0.4/1 by a factor of 7. This reduced the consumption of H2O2 by a factor of 6 and the irradiation time required for complete degradation was reduced by a factor of 6. The experimental results have shown that the optimum reagents for a complete degradation of 4-CP(50ppm) were H2O2.=0.005mol/L, Fe+3=0.16*10-3 mol/L under acidic condition (pH=3) and irradiation time of 15 min for the UV/H2O2/Fe+3 system with a molar ratio of H2O2/Fe+3/4-CP equals to 13/0.4/1.

Urgent requirement for medication from cancer diseases and different microbial infections is interestingly considered. Carbon quantum dots (CQDs) as environmentally friendly fluorescent carbon nano-functionalized materials are popularly considered for application in medical purposes. Herein, a comparative study is presented for the affinity of CQDs ingrained from microcrystalline cellulose (MCC) prepared under hydrothermal conditions (CQDs-HT) versus that prepared under infrared assisted technique (CQDs-IR) for acting as anticancer and antimicrobial laborers. The estimated size averages for the obtained CQDs-HT & CQDs-IR were 7.8 & 9.8 nm, respectively. CQDs-HT showed rationally higher anti-proliferative action against Hepatocellular Carcinoma (HepG2) compared to CQDs-IR. Treatment with 1000 μg/mL of CQDs-IR & CQDs-HT exhibited 78 & 90 % mortality percentage of cancer cells, respectively. The obtained CQDs showed excellent microbicide potentiality and the minimum inhibitory concentration (MIC) from the synthesized CQDs-TH and CQDs-IR was ranged in 100–350 µg/mL and 300–400 µg/mL against different pathogens including bacteria and fungi, respectively. As a conclusion, hydrothermal technique showed seniority over infrared assisted technique in nucleation of CQDs with higher anticancer and microbicidal activities.

The present work describes the fabrication and electrochemical characterization of a novel iron oxide nanopowder-based carbon paste electrodes (CPE) for the sensitive voltammetric quantification of midodrine (MD) in pharmaceutical formulations and biological fluids. At the electrode surface, the postulated reaction mechanism involved the irreversible oxidation of the terminal amino group of midodrine through the participation of two-electron as elucidated by the sweep rate studies and molecular orbital calculations. Calibration graphs were linear in the MD concentration range from 0.16 × 10-6 to 2.12 × 10-6 mol L-1 with LOD 0.04 × 10-6 mol L-1. Prolonged stability with an operational lifetime of more than 4 months and high measurement reproducibility were the promising futures of the fabricated sensors. The proposed electroanalytical approach was free from interference and suggested for assaying of midodrine in its pharmaceutical formulations and biological samples with recovery agreed with the official methods.

The current work proposed a new green procedure that is not sophisticated to recognize and determine the Al(III) ions in multiple water samples. The suggested method was conducted based upon the direct immobilization of aurintricarboxylic acid reagent into the mesoporous silica nanospheres to shape a unique and novel solid sensor. Al(III)-ATA red-complex has been formed at pH 4.0 and spectrophotometrically measured at 525 nm. Moreover, the complexation was reversible, and the ATA sensor retained his functionality even after six-time reuse/cycles using EDTA as eluent. Univariate and multivariate (partial least squares 1, PLS-1) calibration techniques were utilized for calculating the figures of merit for the determination of the Al(III) ions. The obtained calibration curve was linear from 2.0 to 70 ppb Al(III) ions concentration. The developed method has a detection limit of 3.5 ppb. In addition, the ATA sensor showed high adsorption capacity value (118.53 mg/g) which gives it a great advantage to be applicable as nanocollector for trapping Al(III) ions. The novel ATA sensor showed high degree of selectivity, sensitivity, reproducibility, and stability. The current study explores the effectiveness of the ATA sensor for the first time to produce a green solid sensor to determine the trace amount of Al(III) in diverse water types; tap, mineral, river, well, and sea water.

In order to better realize the effects of UV index (UVI) reaching the earth surface, measurements of effective UVI were carried out during the period of one year over Baghdad; (Lat.33.32- Long.44.45), which receives highly amounts of annual solar radiation. A daily data analysis of UVI is found to reach the highest value during summer reaching the value of 11, and a minimum in winter with the value of 1. A relation between UV index and the solar zenith angle was also, it is found that the UVI is highly dependent on the sun elevation where the atmospheric optical path becomes shorter as sun elevation heighten. It can be concluded that Baghdad city exposure to higher amounts of UVI during summer and several hedges must be taken to avoid health harm implications.

Introduction: COVID-19 has harmed the economic, academic, and clinical pursuits of dental educational institutions and dental students. As dental associations, health agencies, and regulatory bodies around the globe announced the need for social distancing and stricter safety measures, some dental schools worldwide have been adapting to accommodate for such changes.Methods: This review attempts to provide a general picture of the early responses of some dental schools worldwide to the COVID-19 crisis and identify some of the regulations that influenced dental schools' initial decisions. An analytical approach was used to assess changes to dental school curriculums in didactic (academic/non-clinical) and clinical education, examinations, administration, and dental school research. The assessment was based on a web-based search of a variety of online global references including research articles, reviews, letters, press releases, and surveys regarding the early effect of covid-19 on dental education at some dental institutions in the U.S, Europe, and Asia from late February to early July of 2020. The review also offered further recommendations to dental school administrators regarding the future of dental education during the early stages of a pandemic.Conclusions: Innovations in technology and blended educational methodologies will continue to influence how certain dental schools around the world adapt to the changes caused by COVID-19 and better prepare dental education institutions for potential future public health disruptions.Clinical significance: Dental schools will need to adapt their education system to improve didactic, preclinical, clinical, administrative, and research components of dental education in response to the changes caused by COVID-19 and future pandemics.

A low-cost, simple, and highly selective method was used for the assessment of total prostate specific antigen (tPSA) in the serum of prostate cancer patients. This method is based on quenching the intensity of luminescence displayed by the optical sensor Eu (TTA)3 phen/poly methylmethacrylate (PMMA) thin membrane or film upon adding different concentrations of tPSA. The luminescent optical sensor was synthesized and characterized through absorption, emission, scanning electron microscopy (SEM), and x-ray diffraction (XRD), and is tailored to present red luminescence at 614 nm upon excitation at 395 nm in water. The fabricated sensor fluorescence intensity is quenched in the presence of tPSA in aqueous media. The fluorescence resonance energy transfer (FRET) is the main mechanism by which the sensor performs. The sensor was successfully utilized to estimate tPSA in the serum of patients suffering prostate cancer in a time and cost effective way. The statistical results of the method were satisfactory with 0.0469 ng mL−1 as a detection limit and 0.99 as a correlation coefficient.

Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants. Tis study intends to describe the clinical signs, gross and histopathological features seen in 25 afected lambs in an outbreak of congenital arthrogryposis with hydrocephalus or hydranencephaly in Al-Muthanna governorate, Iraq afer a large number of stillbirths and musculoskeletal deformities from October 2017 to May 2018. Skeletal muscle hypoplasia was seen in the limbs of the afected lambs accompanied with severe arthrogryposis and gross visible brain malformations. In addition, fetal mummifcations, stillbirths, and dead lambs were also seen. Te most histopathological features in muscle fbers were degenerative lesions and absences of cross-striation accompanied with mild infltration of neutrophils and mononuclear cells in severely afected lambs. Te meninges of afected lambs revealed fused membranes with focal areas of fbrous thickenings and necrotic debris. In conclusion, according to clinical signs, gross and histopathological investigations, Akabane virus, a member of the Orthobunyavirus genus in the family Bunyaviridae, causes congenital abnormalities and arthrogryposis with hydrocephalus or hydroencephaly in ruminants and could be the cause of this outbreak, although future studies must be performed to confrm the etiology of this outbreak. Moreover, other causes of hydrocephalus or cerebellar malformation, such as Schmallenberg virus, bluetongue virus and border disease virus and teratogenic plants that lead to arthrogryposis, have to be investigated. Also, the authorities should take prevention and control measurements to stop the replication of arthropod vectors.

Dirofilaria immitis, the cause of heartworm infestation (HWI) or dirofilariasis, affects members of the Canidae and remains a worldwide clinical problem. In Iraq, dirofilariasis was believed absent until 2009, when the Karbala Governorate was reported as an endemic area for canine dirofilariasis. Consequently, this study intended to investigate the occurrence of Dirofilaria immitis in police dogs in one police academy in Iraq and to study the gross and histopathological changes in 5 dead dogs, as well as to identify the species of the causative parasite using PCR technique. Thirty-nine police dogs, aged between 6 months and 12 years were included in this study. For the microfilariae investigation, 5 ml blood samples were collected from all dogs in EDTA tubes and examined by Knott’s method. The systemic necropsy performed in five dead dogs showed severe clinical signs of dirofilariasis and tissue specimens were sent for routine histopathological processing. For the molecular analysis, adult worms of the detected Dirofilaria spp. were used for DNA extraction and amplification of the cox1 gene. Fifteen of 39 (38.46%) dogs were diagnosed with moderate to severe microfilariasis. The dead dogs revealed typical severe clinical signs of dirofilariasis. Moreover, typical gross and histopathological changes were also seen, accompanied by generalized thromboembolic lesions, suggesting the occurrence of the caval syndrome. The PCR investigation confirmed that D. immitis was the species present in Iraq. In conclusion, this study establishes that Iraq is a newly reported endemic area for dirofilariasis. Moreover, the infestation occurring in these cases most probably happened inside Iraq. The authors recommend doing further epidemiological studies concerning the occurrence of D. immitis in local dogs as well as in the imported dogs in all Iraqi governorates to better understand the epidemiological map of this disease and to introduce an active treatment and preventive program. Awareness and education regarding this disease should be provided to the veterinarians, dog guiders and people in direct contact with dogs, as this disease is one of the important zoonotic diseases.

Revocability is returning a wife of an actual consummated marriage after a revocable divorce . Testifying the revocability Raja is an ordinance by agreement of the jurists. but the difference of opinion revolves around the intended meaning of the ordinance: whether it is expressive of obligation or recommendation. However, the preponderant opinion is that testifying the revocability Raja is expressive of obligation since it makes it easy to prove revocability Raja when there is denial and to reduce cases of divorce when the husband becomes aware of the serious effects consequenton him.

In recent years, the properties of natural fibers and their effectiveness in sound absorption have been widely studied in an attempt to replace traditional sound-absorbing synthetic materials. This is because traditional synthetic fibers carry health risks for humans and have a significant environmental impact. This study includes a summary of previous studies highlighting existing and newly invented natural fiber sound absorbers in three categories: raw materials, plant fibers, and plant residues, which study the mechanism of sound absorption, in addition to several prediction models and widely used acoustic characterization methods. These studies include a comparison of the sound absorption of several natural sound absorbers and fiberglass in two groups of thin and thick materials. These studies have proven that many natural materials have high efficiency in absorbing sound, such as pineapple leaf fibers, which are ideal alternatives to fiberglass. Finally, the concluding section of this analysis provides a future outlook on enhancing the commercial use of plant waste through theoretical research and practical experiments to renew their effectiveness in this field.

Bismuth oxide (Bi2O3) nanoparticles are synthesized and evaluated for their function as materials for solar cells. Bi2O3 solution is inexpensively produced from the Nigella sativa seeds using a green synthetic method. The synthesized Bi2O3 solution is deposited by droplet casting method, and the synthesized nanofilm is dried at 80°C. Subsequently, diagnostic tests such as UV–VIS, XRD, and FTIR are performed on the Bi2O3/glass thin films. By means of the SEM, EDS, AFM, and I–V characteristics in dark and under illumination, the optical and structural characteristics of Bi2O3- nanoparticle films are investigated to determine the optical energy gap and crystalline material. X-ray diffraction reveals the presence of a tetragonal crystal system in the phase. The estimated band-gap energy Eg is approximately Eg1 = 3.6 eV, and FTIR analysis shows the degree of infrared absorption as a function of wavelength to demonstrate the presence of functional groups in bismuth-oxide molecules from Bi–O bonds. SEM–EDS morphology studies examine the occurrence of nanocrystals of various shapes and sizes. Finally, as a bulk heterojunction device, the I–V performance of the solar cell (Ag/Bi2O3/PSi/Si/Ag) deserves attention, and a fill factor FF= 48 is found for a solar-cell efficiency of 2.8%, ideality factor β= 1.35, characterization resistance RCH = 175 Ω, and the parallel resistance = 25.14 Ω·s. This cheap nanoparticle material could be an ideal candidate for future energy applications. [ABSTRACT FROM AUTHOR]
