Authors: Wahyuningrum Diah Retno , Retnaningsih Retnaningsih , Kartasurya Martha Irene 
Published: June 2021

Background: The occurrence of ischemia causes a loss of energy to switch to anaerobic processes resulting in acidosis due to reduced Adenosina Triphosphate (ATP). This condition makes neuron cells apoptotic. Apoptotic of several biochemical substrates in the brain, such as Glial Fibrillary Acidic Protein (GFAP) exit into the circulatory system which is associated with dysbiosis through immunological pathways.Objectives: To determine the effect of giving enteral formula containing protein, phosphatidylcholine, phosphatidylserine, and inulin on GFAP levels in patients with acute ischemic stroke Dr. Kariadi Hospital.Materials and Methods: This study was done in a single-blind RCT. Eighteen ischemic stroke patients were randomly divided into intervention (9 subjects) and control groups (9 subjects). The intervention group received 69 g of the powdered enteral formula three times a day for seven days. The formula contained protein (15 g), phosphatidylcholine (128 mg), phosphatidylserine (32 mg), and inulin (3 g). The subject who had diabetes mellitus received for 14 days at a dose of 34.5 g per day (7.5 g protein with additions 64mg phosphatidylcholine, 16mg phosphatidylserine, 1.5 g inulin). The control group received the standard enteral formula from the hospital, which contains (11.8 g protein without additions protein, phosphatidylcholine, phosphatidylserine, and inulin). GFAP levels by ELISA method (Enzyme-linked immunosorbent Assay) at pre and post-intervention.Results: There was a trend of decreasing GFAP levels before and after in the intervention group towards a better direction from 8.37±4.25 to 8.30±4.9 compared with the control group which experienced an increasing trend from 5.4±1.8 to 7.5±4. There was no significant difference in GFAP levels after intervention between groups (p = 0.7).Conclusions: The addition of protein, phosphatidylcholine, phosphatidylserine, and inulin had no significant effect on GFAP levels.

Background: One of the factors influencing a child's nutritional status is their mother's or caregivers feeding practice. Mother's behavior in feeding their child is affected by many factors such as social & economic factor, the perception of their child's nutritional status and nutrition knowledge. Objective: To determine the correlation between mothers' knowledge about nutrition and behavior in feeding practice; and the correlation between mothers' perception about their children's nutritional status and behavior in feeding practice (energy, protein, fat, and carbohydrate). Methods: This research was a quantitative study with a cross-sectional design. The samples of this study were 89 pairs of mothers and their child who aged between 1 – 5 years selected by cluster sampling. The subjects of this study took place in HDSS's region, which were Ngaglik and Sleman Districts, Sleman Regency, DI Yogyakarta. This study uses a questionnaire about mothers' perception and knowledge and uses a recall 24-hours to measure the mothers' behavior. The analysis techniques used in this study were Mann Whitney Test and Gamma Test.Results: In general, most mothers have excessive feeding behavior to their child. Mothers with high levels of knowledge tend to have excessive feeding behavior for their child in all nutrients categories. However, mothers with a low level of knowledge tend to have less feeding behavior for energy and fat categories. There are significant correlations between mothers’ knowledge about nutrition with mothers’ feeding practice (p-value <0.001; 0.015; <0.001 and 0.001, respectively). But there is no significant correlation between mothers' perception of their children's nutritional status and mothers' feeding practice for energy, carbohydrate, protein, and fat (p-value 0.854; 0.933; 0.594 and 0.985, respectively). Conclusion: There is a significant correlation between mothers' knowledge about nutrition and mothers' feeding practice. On the other hand, there is no significant correlation between mothers' perception of their children's nutritional status and mothers' feeding practice.
Model based optimization of a novel ventricular assist device
Authors: Salesch Tobias , Gesenhues Jonas , Habigt Moriz , Mechelinck Mare , Hein Marc , Abel Dirk 
Published: June 2021

Abstract
This paper presents an optimization-based control scheme for a novel left ventricular assist device. This cardiac support system consists of two pumps connected in series and a buffer reservoir in between them. This novel concept for relieving the left ventricle is designed to allow the pre- and afterload on the heart to be explicitly adjusted and independently of each other. The first pump controls the preload of the heart with a known physiological controller. With an iterative model-based optimization, the afterload is minimized by the second pump while complying with all constraints. The proof of the control concept and a comparison to the classical single pump left-sided cardiac support is performed on a hardware-in-the-loop test bench. The results show that with the new left ventricular assist device concept, the afterload can be reduced compared to the classical cardiac support.
Investigating the digital media engagements of very young children at home: Reflecting on methodology and ethics
Authors: Sandberg Helena , Gillen Julia 
Published: June 2021

AbstractIn the media and communications field, research investigating the digital media engagements of very young children at home has largely been restricted to survey methods relying on parental self-reports. Recognizing that qualitative approaches can provide insights in families’ practices, values, and attitudes, we argue for the fruitfulness of an ethnographic perspective, drawing on three cases from the project “A Day in the Digital Lives of children 0–3;” two in Sweden and one in England. Using the concept of methodological responsibility, we argue that methodology and ethics are intrinsically entwined. We offer reflections on dilemmas and challenges involved in our participatory work with children under three and their families, bringing attention to such issues as ensuring initial and ongoing consent, using a video camera in the home and data sharing and dissemination. Building trust in such sensitive work is a complex process but the rewards are considerable.

Conditions of A-completeness for linear automata over dyadic rationals
Authors: Ronzhin Dmitriy V. 
Published: June 2021

Abstract
We consider the problem of A-completeness in the class of linear automata such that the sets of inputs, outputs and states are Cartesian products of dyadic rationals; systems checked for completeness are comprised of a variable finite set and a fixed additional set. We obtain conditions of A-completeness in terms of maximal subclasses in the cases when the additional set is the set of all unary automata and when the additional set consists of the adder.
Generalized Ricci flow on nilpotent Lie groups
Authors: Paradiso Fabio 
Published: June 2021

Abstract
We define solitons for the generalized Ricci flow on an exact Courant algebroid.
We then define a family of flows for left-invariant Dorfman brackets on an exact Courant algebroid over a simply connected nilpotent Lie group, generalizing the bracket flows for nilpotent Lie brackets in a way that might make this new family of flows useful for the study of generalized geometric flows such as the generalized Ricci flow.
We provide explicit examples of both constructions on the Heisenberg group.
We also discuss solutions to the generalized Ricci flow on the Heisenberg group.

Development of a continuous PET depolymerization process as a basis for a back-to-monomer recycling method
Authors: Biermann Lars , Brepohl Esther , Eichert Carsten , Paschetag Mandy , Watts Marcus , Scholl Stephan 
Published: June 2021

AbstractThis study presents a new approach for the recycling of bilayered PET waste in an efficient, continuous process with a depolymerization degree >97%. The complex PET waste was converted by chemolysis into its monomers ethylene glycol (EG) and the corresponding salt of terephthalic acid (TA) in a twin-screw extruder (TSE). Via this method, the starting materials for PET production were recovered, and highly contaminated PET waste and PET composite materials were transformed into valuable starting materials. The PE layer of the composite PET/PE material remained inert under depolymerization conditions and could be separated by filtration. An increase in the rotational speed by 200 rpm in the TSE reduced the residence time, but the degree of depolymerization was not affected in a proportional manner. Thus, the results indicate that a shorter residence time can be compensated with intensified mechanical agitation due to higher rotational speeds to obtain a similar degree of depolymerization. These results support the potential of this recycling concept to substantially contribute to the implementation of a circular PET economy.
The effect of homogenization on microstructure and hardness of a large-scale high-aluminum Al4.4Co26Cr18Fe18Ni26Ti5.5 Compositionally Complex Alloy cast
Authors: Biermair Florian , Ressel Gerald 
Published: June 2021

Abstract
As any largescale cast material, specific Compositionally Complex Alloys or High Entropy Superalloys contain segregations, leading to unideal, inhomogeneous properties. This work presents the effects of a homogenization heat treatment at 1 150°C for 6 h of a large-scale cast Al4.4Co26Cr18Fe18Ni26Ti5.5 alloy. In order to reveal these effects, homogenized specimens were analyzed and compared to the as-cast state with regard to chemical homogeneity as well as the homogeneity of elemental solution by means of scanning electron microscopy, energy dispersive X-ray spectroscopy as well as X-ray diffraction and hardness measurements. Despite the increased Al content, intermetallic phases and segregations, observable in the as-cast state, dissolve during homogenization. Improved, but not full homogeneity of elemental distribution after annealing can be determined. The improved state of solution and homogeneity agrees with the increasing lattice parameter from 3.572 Å to 3.594 Å and the decreasing hardness from 320.3 HV10 to 245.2 HV10 during homogenization.

Abstract

Objectives
Although coronavirus disease 2019 (COVID-19) prognosis is mostly good in pediatric patients with no underlying diseases, there are a few reports on children with oncological underlying malignancies. This study aimed to describe the clinical and laboratory features of 20 children with COVID-19 who had underlying malignancies in an Iranian referral pediatrics hospital.

Methods
All children under 15-year-old of age with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive real-time polymerase chain reaction (PCR) and presence of an underlying malignancy were included in the study.

Results
In this study, among 20 patients, 11 were male (55%). The mean age of the patients was 6.0 ± 4.1 years. Twelve patients (60%) had acute lymphocytic leukemia, two had acute myeloid leukemia (10%), and six had solid organ tumors (30%). The most common symptoms were fever (65%) and cough (65%). We reported severe pneumonia in seven hospitalized patients (35%) and three patients (20%) required intensive care unit admission and mechanical ventilation. Procalcitonin was normal in 73% of the cases (11 out of 15), but it was highly elevated in four cases (27%). Five patients (25%) had positive blood cultures and a mortality of 20% was reported.

Conclusions
This is the largest study on SARS-CoV-2 infected pediatric patients with underlying malignancies in Iran. Since the risk of exposure to SARS-CoV-2 and even death in children with malignancy, either in the hospital or community setting during the pandemic is high, special precautions to reduce the risk of transmission are highly suggested.
On the primary coverings of finite solvable and symmetric groups
Authors: Fumagalli Francesco , Garonzi Martino 
Published: June 2021

AbstractA primary covering of a finite group 𝐺 is a family of proper subgroups of 𝐺 whose union contains the set of elements of 𝐺 having order a prime power. We denote byσ0⁢(G)\sigma_{0}(G)the smallest size of a primary covering of 𝐺 and call it the primary covering number of 𝐺. We study this number and compare it with its analogueσ⁢(G)\sigma(G), the covering number, for the classes of groups 𝐺 that are solvable and symmetric.

Fixed angle inverse scattering in the presence of a Riemannian metric
Authors: Ma Shiqi , Salo Mikko 
Published: June 2021

Abstract
We consider a fixed angle inverse scattering problem in the presence of a known Riemannian metric. First, assuming a no caustics condition, we study the direct problem by utilizing the progressing wave expansion. Under a symmetry assumption on the metric, we obtain uniqueness and stability results in the inverse scattering problem for a potential with data generated by two incident waves from opposite directions. Further, similar results are given using one measurement provided the potential also satisfies a symmetry assumption. This work extends the results of

Published: June 2021

Abstract
In this work, a series of bimodal polymethyl methacrylate (BPMMA) was fabricated via solution-blending two neat PMMA resins. Rheology, DMTA, thermal infrared imager measurements were used in an attempt to probe the internal structure of the as-prepared BPMMA. It was demonstrated that the thermorheological behavior of the BPMMA was heavily dependent on shear rate, temperature as well as blending ratio. In addition, a typical “V-shaped” response, namely, a dip in storage modulus (G′) followed by an upturn in the plot of G′ versus measuring temperature for D4 (with lower weight-average molecular weight) was observed, characteristic of occurrence of thermorheological complexity. Our experimental results of physical–mechanical testings suggested that the BPMMA had better comprehensive properties than those of their neat PMMA counterparts.
Thermodynamics of the micellization of quaternary based cationic surfactants in triethanolamine-water media: a conductometry study
Authors: Osundiya Medinat O. , Olaseni Segun E. , Olowu Rasaq A. , Owoyomi Olanrewaju 
Published: June 2021

Abstract
The effect of triethanolamine, a solvent with wide technical and industrial benefit on the micellization of an aqueous mixture of cationic surfactants, dodecyltrimethylammonium bromide (DETAB) and hexadecyltrimethylammonium bromide (HATAB) was studied to examining the stability of the mixed micelles at 298.1, 303.1, 308.1 and 313.1 K using the electrical conductance method. The values of the critical micelle concentration (C*) were found to decrease with an increase in the concentration of triethanolamine (TEA). The values of the free energy of micellization (ΔGm) were negative at a particular temperature, and the extent of spontaneity was discovered to increase when the concentration of TEA was increased. However, an increase in temperature was observed to have a negative linear relationship with the spontaneity of the process. The formation of the mixed micelles was an exothermic process, and it was also TEA and temperature-dependent with a trend similar to those observed in the free energy of micellization (ΔGm). The degree of disorderliness of the system was also found to be entropy driven at a higher concentration of TEA. The synergistic interaction between the molecules of DETAB–HATAB in the presence of TEA (0.4% v/v) and the spontaneity of the system was at the maximum at 0.1:0.9 mol fraction ratio and the energetics of the system was discussed based on hydrophobic–solvophobic interaction of the monomers in TEA at elevated temperatures.
Healing Traditions in Coptic Magical Texts
Authors: Dosoo Korshi 
Published: June 2021

AbstractWithin the ‘market of healing’ of Christian Egypt (here broadly considered as the fourth through twelfth centuries CE), ‘magical’ practitioners represent an elusive yet recurrent category. This article explores the evidence for magical healing from three perspectives – first, literary texts which situate ‘magicians’ in competition with medical and ecclesiastical healing; second, the papyrological evidence of Coptic-language magical texts, which provide evidence for concepts of disease, wellness, and their mediation; and finally confronting the question of how these healing traditions might be understood within the methodologically materialistic framework of academic history, using the concepts of placebo and healing as a performance.
The Question of the Effectiveness of Coptic Pharmacological Prescriptions
Authors: Grons Anne 
Published: June 2021

AbstractCoptic pharmacological texts offer a multitude of medical prescriptions concerning various afflictions, such as eye or skin irritations, affections of the viscera, or even psychological complaints. The content of these texts is medical, and in most cases bereft of any magical or religious ideas. They usually compile prescriptions according to symptoms and/or afflictions, without any further organising principle. Only a handful of texts are grouped according to the illness or to the medicinal plants used. Almost every prescription follows a pattern, with four formal elements: 1) the medical indication (or purpose), 2) the (basic) ingredients, 3) the procedure and application, and 4) the effects and/or the effectiveness of a remedy, or further information. In this article, I give an overview of the entire corpus of Coptic medical prescriptions, explore the four main elements, and especially the discussions of efficacy. I also examine the material in light of placebo research, to see whether something like a placebo effect may have influenced how the pharmacological texts were formulated.
Quel corpus pour l’étude du dialecte niçois ?
Authors: Del Giudice Philippe 
Published: June 2021

Abstract
A new project has just been launched to write a synchronic, descriptive grammar of Niçois, the Occitan dialect of Nice. In this article, I define the corpus of the research. To do so, I first review written production from the Middle Ages to the present. I then analyze the linguistic features of Niçois over time, in order to determine the precise starting point of the current language state. But because of reinforced normativism and the decreasing social use of Niçois among the educated population, written language after WWII became artificial and does not really correspond to recordings made in the field. The corpus will thus be composed of writings from the 1820’s to WWII and recordings from the last few decades.
