Published: February 2022

Introduction: While recent studies are still arguing the efficacy of Hydroxychloroquine and Azithromycin to heal patients with SARS-CoV-2 infection, Moroccan’s ministry of health has decided to maintain the protocol using these drugs. The main objective of this study is to characterize the degree and risk of QT prolongation in patients with COVID-19 in association with their use. Methods: This study is a cohort performed at Mohammed V Military Hospital of Rabat, of patients hospitalized with at least 1 positive COVID-19 nasopharyngeal reverse transcriptase polymerase chain reaction (RT-PCR) test result, and who received 10 day of hydroxychloroquine with 7 days of azithromycin from May9 through May26, 2020. Hydroxychloroquine was given orally at 200 mg TID. Azithromycin was given at a dose of 500 mg the first day followed by 250 mg daily for 6 days. Electrocardiogram was performed before the prescription, 2 days after and at the end of treatment. Results: During this period, 327 ECGs were studied, representing 109 unique patients. Their median age was 30 [25.5-44] years and 100% were male. All patients developed a paucisymptomatic form of the virus. Tisdale score varied between 6 and 8 points (89.9%-10.1%). The difference ΔQTc was significant (p<0.01) from day 0 to 10 with a ΔQTc of 16.15 ms. However, the maximal QTc hadn’t exceed 500 milliseconds. None of the patients developed torsades de pointes or any other ventricular arrhythmias. Conclusion: Moroccan experience can reassure the prescribers on the safety of use of this drug combination in the threatening epidemic context.
Research on RFID authentication Protocol in Internet of Vehicles
Authors: Sun Pengcheng , Li Fei
Published: February 2022

With the development of Internet of Vehicles, radio frequency identification technology (RFID) has been widely used in vehicle networks. The classic RFID authentication scheme cannot meet the special security and confidentiality requirements of RFID in Internet of Vehicles. This paper proposes an RFID authentication protocol in the Internet of Vehicles based on the certification center (CA). Through the certification center, you can avoid the Dos attack problem faced by the back-end server and reduce the server's computing burden. At the same time, through the authentication center, the identity authentication of the back-end server, reader and vehicle tag is indirectly achieved, which solves the problems of replay and malicious tracking that are often faced in RFID. The theory of formal logic language GNY proves that the protocol has high security in the Internet of Vehicles.

El Ateneo Mexicano (1840-1850): una constelación cultural intergeneracional
Authors: Madrigal Hernández Erika
Published: February 2022

El objetivo de esta investigación es analizar a la asociación literaria del Ateneo Mexicano (1840-1850) que reunió a la clase intelectual y política de la época, que dominó el espacio público. En este artículo analizo el origen de la asociación literaria, los objetivos que llevó a reunir a un grupo heterogéneo generacional, disciplinaria e ideológicamente, así como su aportación en el campo intelectual y de la cultura escrita. En mi análisis propongo al Ateneo Mexicano como una constelación cultural que reunió a dos generaciones, las cuales identifico como los consagrados y los jóvenes. En este marco, sugiero que en la medida que el Ateneo Mexicano conjugó a un grupo intergeneracional y multidisciplinario con los personajes más doctos en sus materias, el grupo propició un auge cultural en la organización, producción y difusión del conocimiento, que condujo también hacia un nuevo orden en la opinión pública a través de la instrucción de los “nuevos” ciudadanos del México independiente.

Meningoencephalocele is a rare congenital disorder with an incidence of 1–4 cases per 10,000 live births. Meningoencephalocele is a congenital abnormality resulting from a neural tube defect. The male patient was born at term with cesarean section on indication of congenital abnormalities. The patient had a lump on the side of the head since birth. The patient's mother admitted that she did not consume enough folic acid during pregnancy. On physical examination found a lump in the occipital with a size of 15x15 cm. No blood or pus was found. There is a fluctuation and indicates a transillumination. A CT scan of the head without contrast revealed a parietal meningoencephalocele with a regional defect. The patient was given management in the form of a mass dressing with sterile gauze/24 hours, antibiotics, analgesics and meeting the patient's fluid needs. The patient underwent neurosurgical surgery, namely resection of transcranial meningoencephalocele followed by careful observation and monitoring of the baby's vital signs during surgery. After surgery, there was no evidence of cerebrospinal infection and leakage of cerebrospinal fluid. The wound healed completely and there was no sign of increased intracranial pressure during hospitalization. Head circumference was measured and graphed twice a week. The patient's condition was followed up and showed improvement every day. The research method used an empirical case study that investigated a symptom in a real-life setting and it was concluded that the patient had no visible involvement of the brain in the parietal meningoencephalocele and no hydrocephalus, so this patient had a good prognosis. Suggestions for further research is to look at the prognosis and complications in patients so that they can be assessed early and become a doctor's consideration in determining the action to be taken.

Authors: Dadebo Derrick , Obura Denis
Published: February 2022

Dyes are hazardous contaminants normally found in industrial wastewaters necessitating costly and complex technologies for their removal. In this study, clay was used as an adsorbent in the removal of anionic acid red 88 (AR 88) dye from industrial wastewaters by adsorption. The dye removal efficiency and adsorption capacity of clay was studied by batch experimentation with respect to parameters of dye initial concentration, clay dosage, contact time, and pH. The dye removal efficiency of AR 88 improved with increasing dosage (r 0.9826, p < 0.05), contact time (r 0.9821, p 0.000683) and decreased with increasing initial concentration (r - 0.9168, p 0.02844) and pH (r -0.9666, p 0.007297) of the solution. At initial AR dye concentration of 100 mg/L, the removal efficiency and adsorption capacity of 89.7% and 4.38 mg/g, respectively were achieved after equilibrium time of 30 minutes under the optimum conditions of pH 2 and clay dosage 20 g/L. The study thrived in applying an efficient and low-cost adsorbent that could be used as a substitute to high-cost conventional commercial adsorbents in treating industrial wastewater with AR dye coloration

Published: February 2022

Maconellicoccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) is a polyphagous pest introduced in Brazil in 2010. It has been successfully controlled in other countries by the employment of its natural enemies. Based in the economic importance of this pest plus the potential of chrysopids as its controlling agents, herein we report for the first time in Brazil the association of Ceraeochrysa cincta (Schneider, 1851) (Neuroptera: Chrysopidae) with this pseudococcid, evaluate the consumption of females of M. hirsutus by larvae of C. cincta, and the development of this predator when fed with that prey. Five hatched larvae of C. cincta from F2 generation were isolated in a Petri dish in controlled ambient, and fed with ten immature plus ten adult females of M. hirsutus offered and counted daily. The three instars of the predator were considered as distinct treatments. From five C. cincta larvae fed with M. hirsutus, only one had reached adulthood after 28 days. The mean duration of the C. cincta larval period was 20.73 days, with the 1st, 2nd and 3rd instars being 6.40, 5.33 and 9.00 days respectively, but without significantly differences. A mean of 80 immatures and ca. 17 adults of M. hirsutus were predated by the C. cincta in its larval period, with the 3rd instar being the phase of highest consumption of the prey. Based in our results, M. hirsutus is probably not a primary prey of C. cincta, but this chrysopid could be used as an alternative or complementary predator to control this pest.
Pressure-Temperature-Fluid Constraints for the Formation of the Halo-Shakiso Emerald Deposit, Southern Ethiopia: Fluid Inclusion and Stable Isotope Studies
Authors: Nicol Carol-Anne , Marshall Dan , Einfalt Hans Christoph , Thorkelson Derek
Published: February 2022

The Halo-Shakiso emeralds were discovered near the town of Shakiso in southern Ethiopia in 2016. They are gem quality, Cr-dominant emeralds hosted within ultramafic rocks and associated with Cambrian pegmatite intrusions of the Adola Belt. Aqueous-carbonic primary fluid inclusions hosted within emerald have a composition of approximately 3.0 wt.% NaCl eq. and an XCO2 of 0.06, with minor amounts of N2, CH4, and H2S. Stable isotope thermometry of contemporaneous quartz and emerald yields temperatures in the range of 420 to 470 °C. Combined stable isotope and fluid inclusion data are consistent with emerald precipitation at pressures ranging from 2.0 to 3.0 kbar, corresponding to depths of 5.9 to 8.9 km. Additionally, emerald channel water δD and calculated δ18O isotope values are consistent with an igneous origin for the fluids responsible for emerald precipitation; these fluids are also responsible for the metasomatization of the host rocks in and near the pegmatite, forming the phlogopite schist that is host to the Halo-Shakiso emeralds. The isotopic signatures, combined with the occurrence of adjacent pegmatites, support the classification of the Halo-Shakiso emerald deposit as a Tectonic-Magmatic-Related emerald deposit.

Authors: GODIŠ Tomáš
Published: February 2022

Today, teaching foreign languages is mainly influenced by computer technology and the internet, through which the teacher has an unlimited amount of didactic material at their disposal, thanks to which they can teach the language more effectively and at the same time better reflecting on the student’s individual educational needs. Various language programs and mobile applications are also used for teaching, which the students can adapt to their needs. They become an active element of teaching because they can affect the teaching process. Electronic instruments enable teachers to make their lessons more creative and more motivating for their students. However, new technologies also require teachers to have better media skills. There are plenty of workshops and training courses today where teachers can improve this kind of skills. The task of the educational institutions and universities is to improve this kind of competence in the future teacher. In the following article, I will focus on language programs and applications, especially on the Babbel language application, with which I have extensive experience and which is being used more and more often in Slovak schools. I will also demonstrate specific functions for various examples as well as describe problems with its use in the teaching process.

El uso intensivo de agroquímicos para la producción de alimentos en los países en desarrollo ha generado un problema de interés ambiental pues muchas de estas sustancias que suelen ser difíciles de biodegradar pueden alcanzar fuentes naturales generando su contaminación. Es por ello que la búsqueda de nuevas tecnologías para la eliminación de estos contaminantes ha surgido con mucho interés. Los procesos avanzados de oxidación (PAOs), cuya principal característica es la generación de especies altamente oxidantes como el radical hidroxilo, pueden lograr la modificación química del contaminante generando subproductos que pueden ser menos dañinos con el medio ambiente. En este trabajo se evaluó la degradación de metomilo, un insecticida altamente utilizado en la región de Arequipa, Perú, utilizandodiferentes PAOs como la ozonización en medio alcalino, UV-C/H2O2 y procesos foto-Fenton a pH ácido. Se evaluó a escala de laboratorio el efecto de matriz de aniones como bicarbonatos, fluoruros y nitratos y posteriormente en aguas naturales superficiales. Los resultados indican que la mayor eliminación de metomilo en agua real se logró en 99.38 % bajo UV-C/H2O2 seguida del proceso fotofenton, con un 94.12 % de degradación y la ozonólisis a pH alcalino (pH 11) con un 40% de degradación, demostrando que los PAOs evaluados pueden ser una alternativa promisoria para eliminar agroquímicos de fuentes naturales.

Although, the effect of mass flow rate and solar irradiance variation is present in literature, it is still of significant interest to investigate the extent of the effect especially when utilizing a custom absorber design. In this paper, the effect of changing the mass flow rate and solar irradiance on the performance and temperature uniformity of a PVT using a custom spiral absorber design is simulated using ANSYS CFD software. By increasing the mass flow rate, the temperature uniformity and the performance parameters such as the average PV temperature, water outlet temperature, thermal and electrical efficiency all increase. By increasing the irradiance level, performance and temperature uniformity drop albeit at a smaller degree compared to change observed in mass flow rate variation. Amongst the tested range, the optimum mass flow rate and solar irradiance levels for best performance are 40 kg/h and 800 – 1000 , respectively.

The effects of splitter plate as a passive turbulence control on the transverse vibration characteristics of a cantilevered rectangular prism with the different finite length (aspect ratio L/H) and depth ratios (side ratio D/H of 0.2 and 0.5) was investigated in a water tunnel. A splitter plate was installed behind the prism with a small gap and sufficient length to prevent vortex shedding intrusion. It enhances the response amplitude ascended linearly with respect to non-dimensional velocity. In the case of the prisms with critical points, interferences of amplitude signal spectra for the period of displacement vanished, yielding a uniform waveform on the response amplitude. Inserting a splitter plate improves the increment rate of the dynamic response of the test models. A brief numerical calculation was performed to find the quantities of flow features around a plain and rectangular prism with a detached splitter plate. The alteration of flow wake characteristics is found by diminishing unsymmetrical vortices shedding and reduce flow entrainment at the trailing edge. The essential findings of the prism with a detached splitter plate are the base pressure improvement, reducing drag force, and vanishing sharp peaks of wake FFT spectra.
Managing physician conflict
Authors: Ogborn Malcolm
Published: February 2022

Conflict is an intrinsic part of human experience. This article explores the distinction between cognitive disagreement and the emotional experience of conflict. It discusses the sensitivity of physicians to the perception of shame and the impact that shame can have on conflict behaviour. It offers a framework for conversations to navigate conflict and a number of simple strategies physician leaders may employ to work through conflict themselves and within their teams. Although some conflicts require the help of a skilled specialist, most can be facilitated with thoughtful and courageous leadership.

Infrastructure projects (IPs) face numerous challenges to reach the predefined aims over their life-cycle. There are many difficulties in projects because of the variety of elements in project’s tendency and the dependency of the project on mainly national factors. Due to these difficulties and their practices, the projects meet with uncertainty. In this paper, an interval-valued intuitionistic fuzzy set (IVIFS) is used at identifying ambiguity in IPs. Also, a new multi-criteria decision-making (MCDM) model is presented to evaluate and select the suitable alternative in IPs. Hence, a new IVIF-relative preference alternative-multi-attributive border approximation area comparison (IVIF-RPR-MABAC), and IVIF-weighted aggregated sum product assessment (IVIF-WASPAS) are proposed in order to obtain the weights of decision makers (DMs) and criteria, and a new IVIF-RPR-MABAC method is proposed to rank the alternatives. In this paper, a combination of the three mentioned approaches creates proposed new hybrid model to evaluate the main factors and the projects. Furthermore, a real case study is applied from the literature to validate the efficiency and performance of the proposed model. Afterward, a comparative analysis is presented to validate the proposed approach by comparing the hybrid proposed model with two IVIF-TOPSIS and IVIF-extended-VIKOR methods. The final results confirm the efficiency of the proposed model in ranking the main alternatives of an MCDM problem. Moreover, the sensitivity analysis is reported to determine the affection of parameters on the final weighting and ranking outcomes.
Thermal Instability–Induced Fundamental Magnetic Field Strands in the Solar Corona

Thermal instability is a fundamental process of astrophysical plasmas. It is expected to occur whenever the cooling is dominated by radiation and cannot be compensated for by heating. In this work, we conduct 2.5D radiation MHD simulations with the Bifrost code of an enhanced activity network in the solar atmosphere. Coronal loops are produced self-consistently, mainly through Joule heating, which is sufficiently stratified and symmetric to produce thermal nonequilibrium. During the cooling and driven by thermal instability, coronal rain is produced along the loops. Due to flux freezing, the catastrophic cooling process leading to a rain clump produces a local enhancement of the magnetic field, thereby generating a distinct magnetic strand within the loop up to a few Gauss stronger than the surrounding coronal field. These strands, which can be considered fundamental, are a few hundred kilometers in width, span most of the loop leg, and emit strongly in the UV and extreme UV (EUV), thereby establishing a link between the commonly seen rain strands in the visible spectrum with the observed EUV coronal strands at high resolution. The compression downstream leads to an increase in temperature that generates a plume-like structure, a strongly emitting spicule-like feature, and short-lived brightening in the UV during the rain impact, providing an explanation for similar phenomena seen with IRIS. Thermal instability and nonequilibrium can therefore be associated with localized and intermittent UV brightening in the transition region and chromosphere, as well as contribute to the characteristic filamentary morphology of the solar corona in the EUV.

BACKGROUND: Central venous catheter (VC)-related bloodstream infection (CRBSI) is associated with high rates of morbidity and mortality in critically ill patients over the world.

AIM: The aims study is to evaluate the prevalence of CRBSI and to identify some of the factors.

METHODS: This was a retrospective, observational study carried out in the tertiary care hospital “Mother Theresa,” Tirana and American Hospital, Tirana, over a period of 3 years from January 2016 to December 2018. Data were collected retrospectively from various electronic sources shared by the hospitals and linked using patients’ unique medical record numbers. A total of 170 patients with indwelling VC were included in the study. The catheters were cultured using the standard procedure. Statistical analysis version SPSS-20 software was used for calculation of data.

RESULTS: Overall 170 patients analyzed in this study, the prevalence of CRBSI results 58.8%. The positivity from the University Hospital Center (UHC) “Mother Theresa” resulted 65.1% (82/126 cases) and the positivity from American Hospitals (AH) resulted 40.91% (18/44 cases). Patients from UHC Mother Theresa were (odds ratio) 2.69 times higher in risk for CRBSI compared to patients from AH, for confidence interval 95% (1.33–5.44) p value resulted to be with strong association = 0.005. The average age resulted 59.68 ± 14.26, with minimum age 9 years old and maximum age 83 years old. The most infected age groups resulted patients with age 61–70 years old. Central VC had a higher positivity compared to other catheters types. Regarding the spectrum of bacteria implicated in CRBSI infections, Gram positive bacteria (67%) were the most predominant compared to Gram-negative bacteria (33%), but regarding the antimicrobial resistance, the Gram-negative bacteria resulted majority of multidrug resistance.

CONCLUSION: The overall prevalence of CRBSI was 58.8%. Patients from Mother Theresa Hospital have the highest prevalence compared to patients of American Hospital. Men patients were the most predominant sex; age groups 61–70 years old presented the highest positive cases with CRBSI. Staphylococcus spp., Acinetobacter spp., Proteus spp., etc., were the most common isolate. We found antimicrobial resistance almost in all bacteria, but Gram-negative bacteria resulted majority of multidrug resistance.
