Introduction
Authors: Coavoux Samuel
Published: September 2020

Les articles rassemblés dans ce premier numéro de la revue RESET ont pour ambition de revenir sur l’actualité du concept de classe sociale à l’heure de la communication numérique. Alors que le développement des techniques d’information et de communication semble un terrain propice aux discours sur la « fin des classes », comme en témoignent leur succès important dans les médias mais aussi certains travaux sociologiques contemporains, cette introduction revient sur les différents niveaux d’analyse au sein desquels s’inscrit la problématique des classes sociales (en l’occurrence, les inégalités numériques, les pratiques culturelles, et les modes de vie), pour proposer un bilan du débat. La dissociation de la classe réelle et de la classe « sur le papier », la sensibilité aux communautés de modes de vie plutôt qu’aux seules « inégalités objectives » et « consciences de classes », et la fécondité méthodologique de ces perspectives suggèrent ainsi que le concept de classe garde toute sa pertinence pour les sciences sociales et contribue encore à l’approfondissement de la réflexion sur la stratification sociale.

Manifolds Homotopy Equivalent to Certain Torus Bundles over Lens Spaces
Authors: Davis James F. , Lück Wolfgang
Published: September 2020

We compute the topological simple structure set of closed manifolds that occur as total spaces of flat bundles over lens spaces Sl/(ℤ/p) with fiber Tn for an odd prime p and l ≥ 3 provided that the induced ℤ/p‐action on π1(Tn) = ℤn is free outside the origin. To the best of our knowledge this is the first computation of the structure set of a topological manifold whose fundamental group is not obtained from torsionfree and finite groups using amalgamated and HNN‐extensions. We give a collection of classical surgery invariants such as splitting obstructions and ρ‐invariants that decide whether a simple homotopy equivalence from a closed topological manifold to M is homotopic to a homeomorphism. © 2020 The Authors.

First‐Trimester Cranial Ultrasound Markers of Open Spina Bifida
Authors: Zhu Xia , Zhao Sheng , Yang Xiaohong , Feng Qian , Zhang Xiaoyan , Yang Fan , Chen Xinlin
Published: September 2020

Objectives

To evaluate cranial ultrasound markers during a first‐trimester routine ultrasound examination for screening for open spina bifida (OSB).

Methods

Midsagittal and axial images of the fetal head obtained from fetuses with spina bifida and unaffected control fetuses at 11 weeks to 13 weeks 6 days were analyzed retrospectively. The observed markers of the posterior brain included the 4‐ versus 3‐line view, the brain stem (BS)‐to‐brain stem‐occipital bone (BSOB) distance ratio (BS/BSOB), the position relationship between the maxillo‐occipital (MO) line and the midbrain‐BS junction, and the crash sign status.

Results

This study included 9 OSB cases, 2 closed spina bifida (CSB) cases, and 200 unaffected controls. Eight of 9 OSB cases had informative midsagittal views of the head. The 3‐line view (abnormal) and BS/BSOB greater than 1 (abnormal) were observed in 87.5% (7 of 8) and 100% (8 of 8), respectively. The midbrain‐BS junction was below or nearly on the MO line (abnormal) in 100% (8 of 8). Seven of the cases had informative axial views of the head. The crash sign (abnormal) was observed in 85.7% (6 of 7). A 3‐line view was seen in all of the cases that had a positive crash sign. Neither of the 2 cases of CSB and none of the controls had any of the 4 first‐trimester intracranial ultrasound markers of OSB.

Conclusions

The 4 first‐trimester intracranial ultrasound markers investigated in this study appear to be very good markers of OSB, especially a BS/BSOB greater than 1 and an abnormal MO line. The crash sign and 3‐line view were observed in the same fetus. In our study, these ultrasound findings were not helpful in CSB.

Authors: Mesonero Francisco , Juliá Berta , Saldaña Roberto , Savini Claudia , Cañas Mercedes , Cea-Calvo Luis , Feo-Lucas Lidia , Fernández Sabela , Rodríguez-Lago Iago
Published: September 2020

Background

Few studies have examined self-medication with corticosteroids among patients with ulcerative colitis (UC).

Aims

To assess the frequency of self-medication with oral corticosteroids in UC patients, and associated factors and reasons.

Methods

An anonymous, voluntary, web-based survey was administered to adults with UC recruited via a Spanish patient association (ACCU) and hospital gastroenterology departments. Information was provided by patients; no clinical data were collected. Descriptive statistics and comparisons of frequencies are displayed.

Results

Among 546 respondents (mean age 39.9 years, median duration of UC since diagnosis 7 years,) 36 (6.6%) reported self-medication with oral corticosteroids during the past year (once: 23 patients; 2–3 times: 10 patients; >3 times: 3 patients). Self-medication was more common among patients managed in general gastroenterology vs. inflammatory bowel disease clinics [23 (9.0%) vs. 11 (2.9%), P = 0.019], patients with no regular follow-up [4 (22.2%) vs. 32 (6.1%), P = 0.026] and patients with more flares (P < 0.001). Patients who stored steroids from previous flares (17.9% vs. 6.0%, P < 0.001) or who lived with a partner taking steroids (9.3% vs. 1.1%, P = 0.038) were more likely to self-medicate than other patients. Common reasons for self-medicating included the need for quick symptom relief (55.6%), fear of worsening (47.2%) and difficulty in getting an appointment (25.0%). Only seven patients (19.4%) informed their physician when they started self-medicating and only four (11.1%) declared they would not start corticosteroids again.

Conclusion

Self-medication with oral corticosteroids is not a common practice among patients with UC in Spain, but several areas of improvement exist.
Mothers Who Engage in Long-Term Informal Milk Sharing
Authors: McNally Deirdre , Spatz Diane L.
Published: September 2020

Human milk has repeatedly been shown to be the best form of infant nutrition. Many reasons may prevent a family from providing human milk to their child, leaving them to seek other options. One alternative is informal milk sharing, where individuals and families find donor milk through online communities. We present perspectives from three mothers who used informal milk sharing for at least 6 months. Common themes identified are sadness, guilt, and stigmatization of informal milk sharing. Implications for practice include providing families and practitioners with resources for learning about informal milk sharing and navigating the community safely.

Existing methods for the analysis of pesticides in breast milk involves multiple extraction steps requiring large sample and solvent volumes, which can be a major obstacle in large epidemiologic studies. Here, we developed a simple, low-volume method for extracting organophosphates, pyrethroids, carbamates, atrazine and imidacloprid from 100-200 µL of human breast milk. We tested microwave-assisted acid/base digestion and double solvent extraction with 2 or 20 mL of 2:1 (v/v) dichloromethane/hexane, with or without subsequent solid phase extraction (SPE) clean-up. Samples were analyzed by liquid chromatography tandem mass-spectrometry. Analyte recoveries and reproducibility were highest when 100-200 µL milk were extracted with 2 mL of dichloromethane/hexane without subsequent SPE steps. Analysis of 79 breast milk samples using this method revealed the presence of carbamates, organophsphates, pyrethroids and imidacloprid at detection frequencies of 79-96%, 53-90%, 1-7% and 61%, respectively. This study provides a simple, low-volume method for measuring pesticides in human breast milk.

Increasing maternal age in mammals is associated with poorer oocyte quality, involving higher aneuploidy rates and decreased developmental competence. Prior to resumption of meiosis, fully developed mammalian oocytes become transcriptionally silent until the onset of zygotic genome activation. Therefore, meiotic progression and early embryogenesis are driven largely by translational utilization of previously synthesized mRNAs. We report that genome‐wide translatome profiling reveals considerable numbers of transcripts that are differentially translated in oocytes obtained from aged compared to young females. Additionally, we show that a number of aberrantly translated mRNAs in oocytes from aged females are associated with cell cycle. Indeed, we demonstrate that four specific maternal age‐related transcripts (Sgk1, Castor1, Aire and Eg5) with differential translation rates encode factors that are associated with the newly forming meiotic spindle. Moreover, we report substantial defects in chromosome alignment and cytokinesis in the oocytes of young females, in which candidate CASTOR1 and SGK1 protein levels or activity are experimentally altered. Our findings indicate that improper translation of specific proteins at the onset of meiosis contributes to increased chromosome segregation problems associated with female ageing.

Published: September 2020

Background

Vitamin A regulates the adaptive immune response and a modulatory impact on type I allergy is discussed. The cellular mechanisms are largely unknown.

Objective

To determine the vitamin A‐responding specific lymphocyte reaction in vivo.

Methods

Antigen‐specific B and T lymphocytes were analyzed in an adoptive transfer airway inflammation mouse model in response to 9‐cis retinoic acid (9cRA) and after lymphocyte‐specific genetic targeting of the receptor RARα. Flow cytometry, quantitative PCR, next‐generation sequencing, and specific Ig‐ELISA were used to characterize the cells functionally.

Results

Systemic 9cRA profoundly enhanced the specific IgA‐secreting B‐cell frequencies in the lung tissue and serum IgA while reducing serum IgE concentrations. RARα overexpression in antigen‐specific B cells promoted differentiation into plasmablasts at the expense of germinal center B cells. In antigen‐specific T cells, RARα strongly promoted the differentiation of T follicular helper cells followed by an enhanced germinal center response.

Conclusions

9cRA signaling via RARα impacts the allergen‐specific immunoglobulin response directly by the differentiation of B cells and indirectly by promoting T follicular helper cells.
Development of an incipient Paleogene topography between the present‐day Eastern Andean Plateau (Puna) and the Eastern Cordillera, southern Central Andes, NW Argentina

Published: September 2020

The structural and topographic evolution of orogenic plateaus is an important research topic because of its impact on atmospheric circulation patterns, the amount and distribution of rainfall, and resulting changes in surface processes. The Puna region in the north‐western Argentina (between 13°S and 27°S) is part of the Andean Plateau, which is the world's second largest orogenic plateau. In order to investigate the deformational events responsible for the initial growth of this part of the Andean plateau, we carried out structural and stratigraphic investigations within the present‐day transition zone between the northern Puna and the adjacent Eastern Cordillera to the east. This transition zone is characterized by ubiquitous exposures of continental middle Eocene redbeds of the Casa Grande Formation. Our structural mapping, together with a sedimentological analysis of these units and their relationships with the adjacent mountain ranges, has revealed growth structures and unconformities that are indicative of syntectonic deposition. These findings support the notion that tectonic shortening in this part of the Central Andes was already active during the middle Paleogene, and that early Cenozoic deformation in the region that now constitutes the Puna occurred in a spatially irregular manner. The patterns of Paleogene deformation and uplift along the eastern margin of the present‐day plateau correspond to an approximately north‐south oriented swath of reactivated basement heterogeneities (i.e. zones of mechanical weakness) stemming from regional Paleozoic mountain building that may have led to local concentration of deformation belts.
Multiple stages of plant root calcification deciphered by chemical and micromorphological analyses

Published: September 2020

Rhizoliths, that is, roots fossilized by secondary carbonates, have been known for ages and are increasingly used for paleoenvironmental reconstructions. However, knowledge about their formation mechanisms remains limited. This study reports the mineralogical and chemical characterization of rhizoliths at different stages of mineralization and fossilization in the Late Pleistocene loess–paleosol sequence of Nussloch (SW Germany). Scanning electron microscopy coupled with elemental mapping and 13C solid‐state nuclear magnetic resonance were used to concomitantly characterize the mineral and organic matter of the rhizoliths. These joint analyses showed for the first time that large rhizoliths are not necessarily remains of single large roots but consist of numerous microrhizoliths as remains of fine roots, formed mainly by calcium carbonates with only low amounts of Mg and Si. They further revealed that the precipitation of secondary carbonates occurs not only around, but also within the plant root and that fossilization leads to the selective preservation of recalcitrant root biopolymers—lignin and suberin. The precipitation of secondary carbonates was observed to occur first around fine roots, the epidermis acting as a first barrier, and then within the root, within the cortex cells, and even sometimes around the phloem and within the xylem. This study suggests that the calcification of plant roots starts during the lifetime of the plant and continues after its death. This has to be systematically investigated to understand the stratigraphic context before using (micro)rhizoliths for paleoenvironmental reconstructions in terrestrial sediments.

Design

This protocol is a randomized, double‐blind, placebo‐controlled trial.

Methods

This study will be implemented in the Hospital of Traditional Chinese Medicine. Subjects enrolled in this study are hospitalized patients who suffered from moderate to severe pain due to dressing change after incision and drainage. Two hundred patients will be selected and randomly assigned to either an intervention or a control group. The intervention group will get routine pain treatment plus pre‐mixed nitrous oxide/oxygen mixture treatment and the control group will be treated with routine pain management plus medical air treatment. All these patients, medical staff and investigators are blind to the nature of the gas in each cylinder, which is randomized. Data will be collected at baseline (T0), 5 min (T1) after the starting of intervention and 5 min post intervention (T2) for each group. The primary outcome is the level of pain relief at T1 and T2. The secondary outcomes cover physiological parameters, adverse events, satisfaction of patients and health professionals and the acceptance from patients.

Discussion

Results of this study will be discussed and the safety and effect of nitrous oxide/oxygen treatment of pain induced by dressing change will be proven.

Impact

When the finding of this study has an active effect on the treatment of pain caused by dressing change, it may provide more options for nursing staff to choose nurse‐led analgesia techniques and then improving the level and quality of pain care as well as patients’ overall satisfaction with the Anorectal Department in China.

Published: September 2020

Emulsion liquid membrane (ELM) method has been widely applied in the separation process as the alternative of liquid/liquid extraction. This study compared the application of microwave, ultrasonic probe, and centrifuge in breaking the used emulsion. Demulsification efficiency was investigated in term of water content in the membrane phase solution before and after demulsification. The results showed that the use of microwave to break the used emulsion provided demulsification efficiency of 98.10%, while application of ultrasonic probe was able to break emulsion at efficiency of 98.45%. In the meantime, demulsification efficiency of almost 97% was achieved when employing centrifuge at centrifugation speed of 3000 rpm. Considering the energy consumption, it is recommended to apply microwave irradiation for emulsion breaking. It could save energy up to 97% and 99% compared to that of ultrasonic probe and centrifuge, respectively.

Evaluating the effect of the porous and non-porous colloidal silicon dioxide as a stabilizer on amorphous solid dispersion
Authors: Chaudhari Smruti P. , Bhadiyadra Mittal , Dave Rutesh H.
Published: September 2020

Advancement in the discovery of drugs has led to many highly lipophilic compounds with very low water solubility. Amorphous solid dispersion is one of the emerging technologies to increase the solubility of these drugs. The stability of these systems is critical since the high energy system tends to recrystallize, which negates the benefits of these systems. In this paper, we are evaluating the use of colloidal silicon dioxide as a potential stabilizer to stabilize the amorphous solid dispersions. Two types of colloidal silicon dioxide are used: porous colloidal silicon dioxide -Syloid 244 Fp and nonporous fumed silica – Aerosil 200. These silicon dioxides have a high surface area. Two methods of incorporation are used to incorporate silicon dioxide into the solid dispersion. The spray drying method is used to make amorphous solid dispersion. It was found that porous silicon dioxide is better to increase stability as well as increasing dissolution rate and % release of the drug. The addition of silicon dioxide internally to the dispersion increases the dissolution rate, and the addition of silicon dioxide externally increases the stability of the solid dispersion.

Keywords: colloidal silicon dioxide, stabilizer, amorphous solid dispersion, low water solubility

Authors: C. Alexandru
Published: September 2020

The paper deals with an innovative bi-axial tracking mechanism for a group of photovoltaic (PV) modules, which combines the features of the classical platform and string configurations. For the daily movement (corresponding to the primary axis), the sun tracking is performed as in the case of a PV platform, while the elevation movement (around the secondary axis, which is referenced to the primary one) is transmitted similar to the case of a string of PV modules. The sun tracking is conducted by an open-loop control strategy, based on a predefined step-by-step algorithm, which was designed so that to capture as much as possible incident solar radiation with a minimum energy consumption for achieving the orientation. The modeling, simulation and optimization of the solar tracker is performed by using the virtual prototyping package ADAMS.

Published: September 2020

Climate change, economic growth and fossil fuel price volatility are forcing governments and thus society to adopt economical and technical measures in the energy sector to reach sustainability. These actions can be seen as opportunities for the stakeholders that form the energy market and also for new actors that may enter as a consequence of the energy transition that is taking place. In this paper, a description of the energy targets and potential market scenarios in Europe is carried out, together with a review of the policies implemented to achieve these objectives. Within this framework, the possibility of the industry to adopt a crucial role in the development of the new energy market is also analysed. The potential tools for its achievement are also presented, together with some of the techniques and mechanisms that make it feasible. From this study, it can be concluded that the industrial sector will become a major distributed prosumer, providing services to the energy market and facilitating the energy transition towards the decarbonization of the society.s
Methodology for the formulation of medium voltage representative networks in three DSO areas
Authors: Attila Sandor Kazsoki  , Balint Hartmann
Published: September 2020

In the 2020s, in line with international trends, a rapidly increasing photovoltaic penetration is expected in Hungary. These decentralized electricity sources are typically connected to the low and medium voltage distribution network, affecting their operation. The spread of different output power connection demands the development of the network infrastructure. The development directions and opportunities can be examined with software simulation, so the formulation of reference networks is required. In order to get valid reference networks, clustering of real feeders can be a solution. When the clusters and the values of the variables that describe the clusters are defined, the networks can be implemented in simulation software. In this paper, the clustering process of Hungarian distribution networks, the determination of the optimal cluster number, and the reference networks are all presented, on which the effects of the growing photovoltaic penetration in the Hungarian medium voltage distribution network system can be simulated

Published: September 2020

Parameter identification techniques are applied to find suitable values of unknown key input factors into a mathematical model. Usually, these factors are determined through optimization algorithms. In this case, the establishment of consistent initial values, and their corresponding searching ranges (which are unknown), is quite important to provide reliable results after the identification process. In this work, a sensitivity analysis is carried out to evaluate the influence of the main parameters involved in a numerical model used to simulate a common-rail solenoid injector. Experimental measurements for several operating conditions were done, and their results were compared with the model outputs to establish an objective function from which to perform the assessment. As a result of this study, it was established the importance of each parameter included in the model: firstly, those parameters with low variability were selected to be removed from the identification procedure, assuming a value for them that do not affect the model results; finally, the rest of parameters remained in the algorithm. After applying the aforementioned identification process, some accurate results are provided and discussed in order to propose improvements for future works.

The current high penetration rate of distributed energy resources in the smart grid has set up a challenge for energy management and consequently for the supply monitoring and assessment of power quality. Currently, new types of electrical disturbances have appeared, usually multiple, due to the uncontrolled connection of non-linear loads that damage sensitive electronic equipment. For this reason, continuous monitoring is the most effective way to characterize the power system behaviour in order to be able to improve determining the origin of the fault and to have weight bearing to claim damages. Likewise, more holistic indicators that would compute the different network states and deal with big data management in terms of compression and scalability of the measurements are needed. In this context, this article presents a statistical characterization in order to monitor in continuous the voltage supply in a consumer network node through a voltage quality index based on higher-order statistics. The results allow us to conclude that higher-order statistics are capable of establishing a continuous, reliable performance that characterizes the deviations of the voltage supply waveform in an average consumer installation. The method could lead to more feasible solutions for power quality surveillance in the smart grid

Unlike other control strategies seen in the literature, this distributed control strategy takes into account the dynamic behavior of the synchronous generators and the spinning reserve requirements. The distributed control offers a simpler implementation than other proposals, a better integration of renewable generation, a greater reliability against communication failures and it reduces the energy costs. The main objectives of the controllers are minimizing fuel consumption and maximizing renewable generation. Simulation results are obtained using MATLAB/Simulink to verify the effectiveness of the proposed control strategy.

“Israeli Hope in Academia” is a program, designed by Israeli President, Reuven Rivlin. The program is based on the perception that Israeli society is changing, from having a clear majority and several minorities, to a society comprised of four principal sectors that are roughly similar in size. The program acts to encourage a more diverse and culturally competent higher education system that promotes partnership. Over the past year, students from various faculties in the Holon Institute of Technology (HIT), took part in a course called “Green Ambassadors”, which corresponds with the “Israeli Hope” program. In the course, the students studied environmental issues, and then passed that knowledge on to pupils in the religious elementary school “Yeshurun” in the city of Holon, through enjoyable educational activities. In order to illustrate the environmental topics, and to achieve high participation levels of the pupils, the students created a mobile laboratory containing experiments and demonstrations, in which the pupils took an active part. The final questionnaires, answered by the classes teachers, show high rates of pupil participation, understanding and enjoyment. Thus, the course managed to make a significant impact on the community, and achieve the goals set by the “Israeli Hope” program.

In this work, the authors have studied a quadratic boost DC-DC converter to reduce its ripple in the output voltage and the input current. This aim has been obtained by implementing two different solutions: the hardware solution consists on the use of coupled inductors and a notch output filter, the software solution is based on a random PWM and uses uncoupled inductors. The two solutions show a different impact on the output voltage and in the input current ripple. The performance of proposed solutions is evaluated and compared by simulation analysis both in time and frequency domain.

Nowadays, with the strong development of the world's economy, the power system reliability issue is increasingly concerned. A high reliable power system brings peace of mind in production investment, stability in national security, citizen's satisfaction… Therefore, serious researches of the power system reliability problem is very necessary. Based on that researches, we can accurately evaluate the situation, propose operational scenarios, troubleshoot reasonably, plan properly for the future. From there, we can implement the ultimate goal of the power system reliability problem is to maximize the reliability, meeting the nation's development need. However, at present, power system reliability problems in many countries have not yet applied updated and objective assessment tools, only exploiting the surface of the problem. Through the research process, the authors publish this paper to outline the basic concepts, the classification and the parameters of the power system reliability problem. Besides, the paper summarizes in detail the methods of calculating and evaluating power system reliability based on the current mathematical models (Analytical Graph method, State Space method, Failure Tree method, Monte - Carlo method) with examples of each method. Thereby, these methods are compared and indicated the applications in specific situations.

Along  with  the  development  of  bandwidth consuming  services,  fiber  optic  is  being  widely  used, especially  in  the  metro  core  networks.  Many  solutions have  been  proposed  for  designing  optical  network topology.  However,  these  solutions  designed  networks with  a  lot  of  fiber  redundancy.  This  paper  proposes  a solution for designing physical topology of optical metro core  networks with the  objectives of (i) ensuring traffic requirements  between  the  network  nodes,  (ii) minimizing  fiber  cost,  and  (iii)  assuring  the  network survivability.  The  numerical  results  show  that  the proposed  solution  satisfies  those  objectives  and  save more fiber than existing solutions.

Authors: Siddiqui Sazada , Alrumman Sulaiman
Published: September 2020

Effects of clethodim treatment on mitotic cells of P. sativum were studied in the present investigation. Pisum sativum seeds are treated with different concentrations of clethodim varying from 0.01, 0.02, 0.03 and 0.04% for 1 and 2 hrs and their effect on seed germination, radicle length, mitotic index and chromosomal anomalies were investigated. The outcomes reveal that treatment of clethodim on P. sativum seeds diminishes seed germination, radicle length, and mitotic index in dose-dependent manner. Also, in clethodim treated seeds which are time and concentration dependent, an escalation in the proportion of abnormal mitotic phases was observed. C-mitosis, fragments, precocious separation, stickiness and bridges were the most frequently observed deviations. The results revealed that frequently used herbicide clethodim has a substantial cytotoxic effect on P. sativum.

It is probably almost a consensus of experts that the Covid-19 pandemic is an undiscovered virus, and its negative impact touches almost the entire joints of human life; Social, economic, banking, tourism, and education. The impact of the life joints mentioned at the beginning may be overcome by certain stimuli and within a certain period of time can be recovered. But the impact that touches the joints of the last Life (education), especially related to the quality of education, the Resolution requires "collective ijtihad" with a wide range of perspective, and must be sustained by the comprehensive stimulus. Given the whole quality of the joints of human life is determined by the quality of education.

In order to collective ijtihad against the impact of the Covid-19 in this field of education, there is an honorable institution that loses its "fangs". The Board of Education (especially the District Education Council) as a representation of the community in the field of education should present contribute its role to help the heavy burden of society in education, especially in the midst of the Covid-19 vortex and its impacts,

The Board of Education must be able to attend: (a) as a advisory agency for local governments in the determination of the implementation of education policies, especially during the pandemic Covid-19 period; (b) As supporting agency, whether financial, thinking or energy for exclusivity in the organizing of education; (c) As a controlling agency for the education policy of the local government; and (d) as a mediator agency on policies implemented by exclusivity and legislative
