Varicella zoster virus fetopathy occurs in infants after infection with varicella-zoster virus from mother during the first two trimesters of pregnancy. The authors describe the case of a female infant, aged 4 months, which came under observation for neuro developmental delay for chronological age. Neurological exam, abnormalities detected on ophthalmologic examination, maternal history of gestational varicella and increased IgG titer to varicella-zoster virus supported the diagnosis of varicella zoster virus fetopathy. Varicella zoster virus fetopathy is a condition characterized by severe skin damage, ocular, skeletal and nervous system anomalies to whom the primary prophylaxis is extremely important. In rare cases, like that presented, the clinical picture may be incomplete only neurological and ophthalmic manifestations was present.

We present you an atypical case of type 1 diabetes mellitus at onset, with multiple abscesses, diagnosis confirmed afterwards by laboratory tests. This report is of a 14 year-old girl, who presented with abscesses of thighs, hypogastric and inguinal area. The regular investigations performed pointed out hyperglycemia with glucose in the urine, accompanied by weight loss, polyuria and polydipsia. The abscesses were incised and drained. The pathological signs of the clinical examination were: influenced general status, decreased skin turgor, dry lips, multiple fistulized abscesses of the thighs and hypogastric area, hyperemic pharynx and tonsils. The blood tests revealed hyperglycemia (272 mg/dl), leukocytosis with granulocytosis, thrombocytosis, and increased values of hemoglobin. The clinical and paraclinical data were suggestive for type I diabetes mellitus, complicated with abscesses. The treatment consisted in substitutive treatment with insulin associated with antibiotics, antimycotics, analgesics, antipyretics, endo-venous perfusions for rehydration. The evolution of the case was favorable under treatment with insulin, the condition of the cutaneous abscesses improved very much after surgical treatment and administration of antibiotics, but they healed only after the equilibration of diabetes mellitus. In conclusion, even though in the specialty literature it is reported that there appear multiple cutaneous infections in patients with diabetes mellitus wrong treated, these are rarely diagnosed at the onset of this disorder in children, this fact being probably explained by the acute onset of the disease at this age.

Introducere. Expunerea la diverse medicamente cardiovasculare şi non-cardiovasculare, substanţe de abuz, substanţe chimice sau porţiuni de plante poate genera hipertensiune arterială secundară. Autorii raportează experienţa personală legată de hipertensiunea arterială secundară intoxicaţiilor acute la copil şi adolescent. Material şi metodă. Am condus un studiu prospectiv pe o perioadă de 24 de luni în care am inclus 151 de copii şi adolescenţi cu afectare toxică cardiovasculară. Pentru depistarea cazurilor de hipertensiune arterială secundară, semnele vitale au fost analizate la internare şi în dinamică ţinând cont de valorile normale pentru vârstă. Rezultate. 11,1% din totalul cazurilor de intoxicaţie acută internate şi tratate în departamentul nostru au asociat afectare toxică cardiovasculară. Dintre acestea, 18,5% au fost cazuri de hipertensiune arterială secundară. Principala cauză a hipertensiunii arteriale în lotul studiat a fost expunerea la insecticide organofosforice, urmată de expunerea la medicamente simpatomimetice. În cazul insecticidelor organofosforice am constatat un comportament dual. Pacienţii au prezentat la debutul intoxicaţiei o scurtă perioadă de tahicardie şi hipertensiune arterială, ulterior instalându-se tabloul colinergic clasic din intoxicaţia acută cu insecticide organofosforice, cu bradicardie şi/sau hipotensiune arterială. Toate cazurile de hipertensiune arterială identificate au fost creşteri tranzitorii, autolimitate ale valorilor tensiunii arteriale, ce nu au necesitat asocierea agenţilor hipotensori în abordarea terapeutică. Concluzii. Intoxicaţiile acute ale copilului şi adolescentului se pot complica cu hipertensiune arterială, cel mai adesea uşoară şi tranzitorie. Monitorizarea semnelor vitale este esenţială pentru abordarea acestor cazuri. Personalul medical trebuie să cunoască temeinic particularităţile legate de vârstă, inclusiv intervalele de referinţă pentru valorile tensiunii arteriale la copil şi adolescent.

Fetopatia varicelo-zosteriană apare la sugar în urma infecţiei cu virus varicelo-zosterian la mamă în primele două trimestre de sarcină. Autorii descriu cazul unui sugar de sex feminin, în vârstă de 4 luni, care a ajuns în observaţie pentru întârziere în dezvoltarea neuropsihomotorie pentru vârsta cronologică. Tabloul neurologic, anomaliile evidenţiate la examenul oftalmologic, istoricul matern de varicelă gestaţională şi titrul crescut al IgG pentru virusul varicelo-zosterian au susţinut diagnosticul de fetopatie varicelo-zosteriană. Fetopatia varicelo-zosteriană este o afecţiune rară, dar severă, caracterizată prin semne cutanate, oculare şi neurologice şi la care profilaxia primară este deosebit de importantă. În cazuri rare, ca şi cel prezentat, tabloul clinic poate fi incomplet, fiind prezente doar manifestările neurologice şi oftalmologice.

Objectives. The aim of this study was to determine the manner in which the level of exhaled nitric oxide (FENO) influences the atopic status in children with asthma. Methods. The study included 92 asthmatic children (aged 5-18 years) admitted on the Pediatric Clinic of “Grigore Alexandrescu” Emergency Clinical Hospital for Children. The atopic status was evaluated through anamnesis, clinical examination and laboratory determination of serum eosinophils and total Ig E. All children underwent measurement of FENO. Results. Children with atopic asthma had higher levels of FENO than children with nonatopic asthma. The FENO values correlate with eosinophilia and high values of immunoglobulin E. Conclusion. FENO is a useful marker for the evaluation of airway inflammation in children with atopic asthma.

Introduction. Exposure to various cardiovascular and non-cardiovascular drugs, drugs of abuse, chemicals and plants may cause secondary hypertension. The authors report their personal experience related to secondary hypertension due to acute poisoning in children and adolescents. Materials and methods. We conducted a 24 month prospective study that included 151 children and adolescents with acute poisoning who developed cardiovascular abnormalities. In order to detect cases of secondary hypertension, vital signs were assessed on admission and in evolution, considering the normal values by age. Results. 11.1% of all cases with acute poisoning admitted and treated in our department have associated cardiovascular impairment. Of these, 18.5% were cases of secondary hypertension. The main cause of hypertension in the study group was exposure to organophosphate insecticides, followed by exposure to sympathomimetic drugs. We noticed a dual effect exerted by organophosphate insecticides. At the beginning patients experienced a short period of tachycardia and hypertension, followed by the installation of the classic cholinergic feature of acute poisoning with organophosphate insecticides, with bradycardia and / or hypotension. All cases of hypertension were transient, self-limiting elevations of blood pressure, which did not require association of antihypertensive agents in the therapeutic approach. Conclusion. In children and adolescents, acute poisoning may be complicated by hypertension, which is mostly mild and transient. Vital signs monitoring is essential to address these cases. Medical staff must know thoroughly age peculiarities, including reference ranges for blood pressure in children and adolescents.

Eventration of the diaphragm, congenital or acquired, represents a rare condition (1 to 10,000 live births), in which the dome of the diaphragm is abnormally elevated, due to an excessive amount of fi bro-elastic diaphragmatic tissue. The child may be asymptomatic or present with respiratory symptoms as aggressive as life threatening respiratory distress. Recurrent pulmonary infections are the commonest presenting complaints. We present the case of a 3 years old boy with recurrent chest infections and apparent “dextrocardia”, both caused by a left eventration of the diaphragm, successfully treated by plication.
Water Infiltration into Sand, Silt, and Clay at Field Capacity
Authors: Goh Eng Giap  , Rudiyanto  , Mohd Sofiyan Sulaiman
Published: July 2021

Field capacity (FC), permanent wilting (PWP), and plant available water (PAW) are essential parameters to estimate for soils because they are essential for water irrigation management. However, these parameters were reported in water volume per unit soil volume. Knowing the soil required water volume does not imply immediate water availability, that is, the speed at which the water could be supplied to the soil. This is because there is a lag time between water irrigation initiation and the water increment in the soil depth. This study uses the field capacity’s soil water content to simulate the water infiltration using Richards’ equation. The studied soil medium was silt, sand, and clay. The study allows an estimate of water infiltration time and infiltrated water to relate to the soil depth of interest. The clayey has the highest FC, and the silty soil has the highest PAW. The results revealed silty soil could contain more readily water for plant growth than sand and clay. This study also revealed silty soil to be a better soil medium than sand and clay. It has the best tradeoff between water infiltration time and the infiltrated amount of water for plant absorption. This study’s coupling technique will be a useful tool for farmers and field practitioners to assess any site based on the soil texture at an early stage of water irrigation investigation.
Numerical Investigation of The Air Flow Rate Effect Performance of Earth to Air Heat Exchanger Used for Cooling of Poultry Houses
Authors: Mushtaq I. Hasan  , Dhay Mohammed Muter
Published: July 2021

Usually, poultry houses are located in a remote area where there is no electricity, and where there is electricity, it is expensive, so resorting to these solutions is considered important solutions to save electrical energy and provide free cooling. The main part of generated energy is consumed by cooling and heating systems. One of the well-known approaches to implemented heating and cooling system is earth to air heat exchanger (EAHE) system. This system is effective passive heating and cooling systems which can be used with poultry houses and building. This research studies numerically the effect of mass flow rate on the overall performance of earth to air HE for poultry houses. Four parameters (mass flow rate, required rate, required cooling load and pipe lengths) are selected under environment of Nasiriyah city (a city located in the south of Iraq). The study is conducted using PVC material. The study has been done during summer season. The suggested numerical model has been tested and validated using existing approaches selected from literature review papers. This test shows good agreement with results of selected papers. Moreover, validation and simulation results showed that the required cooling load increased with increasing mass flow rate. Also, with the increasing length of pipe of EAHE, the inflow temperature compared to the space temperature is decreased. However, the overall performance factor of EAHEs decreases by the increase of length of pipe and mass flow rate. Which indicate the possibility of using the earth to air heat exchanger for cooling and heating poultry houses and reduce the use of electrical energy.

Published: July 2021

Este trabajo parte del análisis de las versiones orales conservadas de El vendedor de nabos (Índice General del Romancero Hispánico: 0765), tema del repertorio romancístico al que se ha dedicado una escasa atención crítica. En concreto, se examinan 54 muestras orales del romance con objeto de determinar su configuración textual y los factores que condicionaron sus formulaciones literarias. Según la hipótesis sostenida en este estudio, existe un reducido grupo de versiones que representan la rama más antigua de la tradición, posiblemente surgida como resultado de la oralización de un texto de cordel; y, por otro lado, un número mucho más amplio de muestras cuya evolución textual estuvo condicionada, según la propuesta argumentada, por los diferentes contextos en los que se transmitieron.
A Neglected Religious Thinker: José María Blanco White (1775-1841)
Authors: ACLE-KREYSING ANDREA
Published: July 2021

‘Dissent is the great characteristic of liberty’ was the central tenet in the life of José María Blanco White (1775-1841), a Spanish exile in Britain, whose fame as a man of letters often obscures the fact that he was first and foremost a religious thinker. The milestones of his life were set by his conversions, from Catholicism to Anglicanism (1814), and finally to Unitarianism (1835). Yet his theological ideas continue to be the least researched part of his oeuvre, mostly due to the problematic reception of his work, so that the ex-Catholic Blanco White - rather than the Protestant Blanco White - continues to occupy centre stage. This article reconstructs the spiritual biography of Blanco White, showing how skilfully he navigated through the world of European Protestantism, arguing that it was in Observations on Heresy and Orthodoxy (1835) that he reached the peak of his creative powers as an original religious thinker.
Elegir el mal menor: las derivaciones de un debate ético-económico medieval en El Conde Lucanor
Authors: MORENO RAÚL ÁLVAREZ
Published: July 2021

Este artículo investiga el exemplum 38 del Conde Lucanor, en el que un hombre muere cruzando un río tras decidir no soltar su tesoro, que apenas ha recibido atención de la crítica. Sin que se conozca el origen de la historia, tras proponer dos potenciales fuentes dominicas y estudiar el contexto económico-social, planteamos que, más allá de una condena abstracta del pecado de la avaricia, don Juan Manuel reprueba la acumulación de riquezas por el estamento no nobiliario. El exemplum podría leerse además como una variante del debate escolástico de los actos voluntarios e involuntarios (elección), desarrollado por figuras como Tomás de Aquino. Esta doble lectura confirmaría, además de algunos de los aspectos apuntados por la crítica tradicional para el Conde Lucanor (relevancia cultural del reinado de Sancho IV, conexión dominica, necesidad de leer los exempla en conjunción con el resto de partes…), la mayor complejidad semántica sugerida por críticos como Laurence de Looze o Jonathan Burgoyne.
Who Translated Lorca into English First? An Analysis of the 1929 New York Translations and their Possible Authorship
Authors: WALSH ANDREW SAMUEL
Published: July 2021

This article analyses the disputed and currently unresolved issue of who was responsible for the first translations into English of the work of Federico García Lorca. These were versions of two of the Gypsy Ballads, which were published anonymously in August 1929 in the New York based Hispanic journal Alhambra, shortly after Lorca’s arrival in the city. The article first presents the background to these translations and the publication in which they appeared, and examines the respective biographical merits and circumstantial claims of the two candidates to be Lorca’s first translators into English, Philip Cummings and Ángel Flores. The article then analyses the textual characteristics of the translations, compares and contrasts them with the translational styles of both candidates in their other Spanish-English poetry translations, and offers some conclusions as to who was most likely to have been Lorca’s first translator into English.
Narrativas del desierto: la literatura mexicana ante la crisis actual de derechos humanos
Authors: MARTÍN FRANCISCO CARRILLO
Published: July 2021

Este artículo analiza uno de los motivos, el viaje de la ciudad al desierto, más reiterados en la literatura mexicana de las últimas tres décadas. El espacio de partida simboliza la promesa moderna de progreso; el de destino, el fracaso de esta, sustituida por una dimensión donde la mirada letrada cede ante los lenguajes del crimen organizado, la desaparición forzada o el tránsito migrante. Tal desplazamiento caracteriza las ‘narrativas del desierto’ a las que me refiero en el título, así como los tres archivos que surgen de ellas y articulan el presente trabajo: el archivo necropolítico hace referencia a la crisis de derechos humanos que ejerce de motor de estas escrituras. El archivo de género a la conciencia feminista que muestran y al hecho de que el feminicidio se destaque como uno de sus principales ejes temáticos. Por último, el archivo migrante surge de un viaje que oscila del ámbito argumental al formal, como propuestas que cuestionan la unidad del libro y las lógicas del mundo editorial. A través de estos tres archivos trazo un panorama de la literatura mexicana de hoy.
Revealing the Physical Conditions around Sgr A* Using Bayesian Inference. I. Observations and Radiative Transfer

Published: July 2021

We report subarcsecond Atacama Large Millimeter/submillimeter Array (ALMA) observations between 272 and 375 GHz toward Sgr A*'s circumnuclear disk (CND). Our data comprise eight individual pointings, with significant SiO (87–76) and SO (7–6) emission detected toward 98 positions within these pointings. Additionally, we identify H2CS (91,9–81,8), OCS (25–24), and CH3OH (21,1–20,2) toward a smaller subset of positions. By using the observed peak line flux density, together with a Bayesian inference technique informed by radiative transfer models, we systematically recover the physical gas conditions toward each of these positions. We estimate that the bulk of the surveyed gas has temperatureTkin< 500 K and densitynH⪅ 106cm−3, consistent with previous studies of similar positions as traced by HCN clumps. However, we identify an uncharacteristically hot (Tkin≈ 600 K) and dense (nH≈ 106cm−3) source in the Northeastern Arm. This position is found to be approximately consistent with a gravitationally bound region dominated by turbulence. We also identify a nearby cold (Tkin≈ 60 K) and extremely dense (nH≈ 107cm−3) position that is again potentially bound and dominated by turbulence. We also determine that the total gas mass contained within the CND isMCND≲ 4 × 104M⊙. Furthermore, we qualitatively note that the observed chemical enrichment across large scales within the CND is consistent with bulk grain processing, though multiple desorption mechanisms are plausibly responsible. Further chemical modeling is required to identify the physical origin of the grain processing, as well as the localized H2CS and OCS emission.
Model-Driven Engineering for End-Users in the Loop in Smart Ambient Systems
Authors: Trouilhet Sylvie , Arcangeli Jean-Paul , Bruel Jean-Michel , Koussaifi Maroun
Published: July 2021

At the heart of cyber-physical and ambient systems, the user should permanently benefit from applications adapted to the situation and her/his needs. To do this, she/he must be able to configure her/his software environment and be supported as much as possible in that task. To this end, an intelligent “engine” assembles software components that are present in the ambient environment at the time and makes unanticipated applications emerge. The problem is to put the user “in the loop”, i.e., provide adapted and intelligible descriptions of the emerging applications, and present them so that the user can accept, modify or reject them. Besides, user feedback must be collected to feed the engine’s learning process. Our approach relies on Model-Driven Engineering (MDE). However, differently from the regular use of MDE tools and techniques by engineers to develop software and generate code, our focus is on end-users. Models of component assemblies are represented and made editable for them. Based on a metamodel that supports modeling and de- scription of component-based applications, a user interface provides multi-faceted representations of the emerging applications and captures user feedback. Our solution relies on several domain- specific languages and a transformation process, based on the established MDE tools (Gemoc studio, Eclipse Modeling Framework, EcoreTools, Sirius, Acceleo). It works in conjunction with the intelligent engine that builds the emerging applications and to which it provides learning data.
Wet grinding of invertebrate bulk samples – a scalable and cost-efficient protocol for metabarcoding and metagenomics
Authors: Buchner Dominik , Haase Peter , Leese Florian
Published: July 2021

Most metabarcoding protocols for invertebrate bulk samples start with sample homogenisation, followed by DNA extraction, amplification of a specific marker region, and sequencing. Many of the above-mentioned laboratory steps have been verified thoroughly and best practice strategies exist, yet, no clear recommendation for the basis of almost all metabarcoding studies exists: the homogenisation of samples itself. Two different categories of devices are typically used for homogenisation: bead mills or blenders. Both have upsides and downsides. Bead mills rely on single-use plastics and therefore produce a lot of waste and are expensive. In addition to that, processing times can go up to 30 minutes making them unsuitable for large-scale studies. Blenders can handle larger sample volumes in a shorter time, and be cleaned – yet suffer from an increased risk of cross-contamination. We aimed to develop a fast, robust, cheap, and reliable sample homogenisation protocol that overcomes limitations of both approaches, i.e. does not produce difficult to discard waste and avoid single-use plastics while reducing overall costs. We tested the performance of the new protocol using six size-sorted Malaise trap samples and six unsorted stream macroinvertebrate kick-net samples. We used 14 replicates per sample and included many negative controls at different steps of the protocol to quantify the impacts of i) insufficient homogenisation and ii) cross-contamination. Our results show that 3-min homogenisation is sufficient to recover about 80% of OTUs per sample in each replicate and that a non-hazardous DIY cleaning solution provides an effective and efficient way of cleaning. The improvements of the protocol in terms of speed, ease of handling, an overall reduction of costs as well as the documented reliability and robustness make it an important candidate for sample homogenisation after sampling in particular for large-scale and regulatory metabarcoding but also metagenomics biodiversity assessments and monitoring.

Published: July 2021

The substitution of the normalized aggregate by residual foundry sand (WFS) was studied on the physical properties of mortars by means of resistance to compression and capillary absorption tests. The aggregate was replaced by WFS in its natural state (WFS), washed residual foundry sand (WFSW) and heat treated residual foundry sand (WFST). The WFS had a percentage of bentonite, which was sought to be thermally activated. It was found that the physical behavior of the mortars containing WFS and WFSW was similar to that of the control sample. The clay recovered from the sand washing was evaluated for its pozzolanic potential, it was found that, with the thermal treatment, the montmorillonite acquires pozzolanic behavior. Mortars with WFST presented a drop in compressive strength. The pozzolanic effect achieved in the clay was not reflected in the compressive strength of the mortars with WFST.

Recent research has been very attentive to the examination of learners’ behavioural patterns of using learning management systems (LMS), but these studies seldom address the diversity in the LMS usage behaviours of teachers. This study aimed to discover the behavioural patterns of university instructors regarding the use of an LMS by using sequential and clustering analysis techniques. The usage behaviours of 268 teachers at a public university in China were extracted from the Blackboard platform over the course of one-semester. These behaviours were classified according to five different LMS behavioural types: (1) course and content; (2) assignment; (3) communication and collaboration; (4) assessment; and (5) administration. The results indicated that the most frequent teachers’ LMS usage behaviour was course and content followed by assessment and administration. The results of the sequential analysis indicated that most of the instructors are used to adopting communication and collaboration and assignment when they finish using course and content. In addition, three distinct usage behavioural pattern subgroups were named as teachers preferred assessment, teachers of regular use, and teachers of less use. Implications of these findings are discussed in the light of the university teachers’ behavioural patterns toward using the LMS.

Financial management is one of most important type of professional courses in the discipline of business management. The information-based teaching of the courses is a hot spot in the research of professional education. As a cutting-edge information technology, webpage technology provides a good information carrier that enables fast sharing, timely access, and opinion exchange of information. The application of information technology to distance education of financial management could promote the learning efficiency of the students. This paper mainly designs a computer-based distance education system with the aid of dynamic webpages. The system encompasses such modules like database, classroom module, and question and answer (Q&A) module. By introducing the operating mechanism of the system, this paper fully integrates the teaching resources and practices of financial management into the dynamic webpage-based system, providing students or trainees a convenient way of online learning. Through the integration of information technology in education, the proposed system promotes the reform of traditional education model, helps to improve teaching quality and learning efficiency, and enhances the students’ ability to analyze and implement financial management.

Mobile ad hoc network (MANET) is among the networks which do not require any infrastructure to put nodes in communication. Due to its own nature, it is used by several applications. Even though it's a network that is extremely challenging and mostly when TCP is applied. In this paper, we have proposed a new improvement in the TCP algorithm that employed fuzzy logic to predict packet loss and avoid congestion. Specifically, we have used tree metrics such as stability, energy, and signal strength to use in fuzzy logic systems. To accomplish our approach, we have established some modifications based on a cross-layer. The results of the relevant simulation performed by NS3 demonstrated that our approach globally improves the performance of TCP in MANET. Precisely reduce the packet overhead and energy consumption also enhance throughput.

Powders of X6CrNiTi18-10 stainless steel were fabricated from original workpieces of different grade by gas atomization method. It was found that it is necessary to use argon as a gas for gas atomization of X6CrNiTi18-10 steel, since the use of nitrogen leads to the formation of its compounds, namely, titanium nitride. It is shown that all used workpieces – electric arc, electric slag and vacuum arc refinement – allow one to obtain powders suitable for further utilization in selective laser melting technology of 3D printing. The main physicochemical and technological properties of the obtained powders have been investigated. Changes in the chemical composition and quality of the powders are not significant within the X6CrNiTi18-10 grade. The 0...20 μm fraction of powders does not have fluidity, and thus cannot be used for additive technologies. The fraction 20...63 μm have suitable rheological properties for additive technologies and may be used in selective laser melting (SLM) process. The yield of target fraction 20 ... 63 microns was ≈45%. The fraction 63...120 μm may be used for the direct metal deposition (DMD) additive technology. Considering the economic aspect of the technology, it is preferable to use original workpieces of X6CrNiTi18-10 steel produced by electric arc or electroslag process, since the market price of vacuum arc steel is significantly higher. The fraction of ferrite phase in the powder increases with a decrease of particle size of the resulting powder and is lower comparing to the original workpiece. In the future, for a detailed study of the technological properties, it is planned to grow samples from each type of the obtained powders on installation for selective laser melting and direct laser deposition to determine the physical and mechanical properties of fabricated samples (tensile and impact bending tests) and carry out metallographic studies.
