Fire Resistant Geopolymers Based on Several Clays Mixtures
Authors: Gharzouni Ameni , Alizé Clément , Rossignol Sylvie
Published: July 2021

This chapter aims to highlight the effect of clay mixture mineral composition and alkali concentration of potassium alkaline solutions on the thermal behavior of geopolymer materials. For this, three mixtures composed of kaolin (pure, impure kaolin or mixture of both), calcium carbonate, sand and potassium feldspar and three potassium alkaline silicate solutions with different concentrations were used (5, 6 and 7 mol.L−1). At first, the effect of rotary calcination parameters at 750°C such as the dwell time (30, 60, 120 and 180 min) and weight powder (100, 400 and 500 g) was investigated. It was demonstrated that the kaolin dehydroxylation is quasi complete (> 90%) and do not significantly depend on the dwell time and powder weight. Whereas the carbonate decomposition degree increases with the increase of dwell time and the decrease of powder weight but still not complete (<80%). These differences influence the feasibility of consolidated materials. Indeed, a flash setting occurs for samples based mixtures with high calcium carbonate decomposition degree (> 50%) and low wettability values (500 μL/g) for the three used alkaline solutions. The thermal behavior at 1000°C depends on the chemical composition of the aluminosilicate source and the concentration of alkaline solution. A conservation of the compressive strength at 43 MPa after thermal treatment at 1000°C of geopolymers based on mixture of pure and impure kaolin and a low potassium concentration solution (5 mol.L−1) was evidenced.

Authors: Subirosa Sabarguna Boy
Published: July 2021

The explanation begins with the Clinical Pathway in Hospital which describes how the Clinical Pathway is used in relation to 2 things: Components-Linkages and Step-Problems-Optimal Solution, followed by Linkages Clinical Pathway with Quality Improvement and Cost Containment, which describes the relationship of each. Followed by the Clinical Pathway for Service Quality: which consists of: (1) Clinical Pathway for Service Quality, (2) Patient Safety for Service Quality Improvement, (3) The role of alogarithm, thereby clarifying the form of clinical pathways in quality improvement efforts that ensure service improvement by still maintain the quality that is maintained during the cost containment. The Clinical Pathway in Cost Containment describes the roles of: (1) Link of Components, (2) Procedure, (3) Unit Cost, so that cost containment efforts can be made in the form of cost containment optimally while maintaining quality does not need to decrease. Clinical Pathway in New Era is a newly developed algorithm related to current and future conditions. This is related to: (1) New Era in Pandemic Covid-19, (2) Clinical Pathway in Non Curative Service, (3) Clinical Pathway in Technology Services, (4) Clinical Pathway in Technological Rerelated while continuing to carry out quality improvement and cost containment simultaneously. Concluton: clinical pathway in hospital can be used as a system for Quality Improvement and Cost Containment, related to New Era in Pandemic Covid-19, Non Curative Service, Technology Services and Technological Rerelated.
Home Based Palliative Care
Authors: Goswami Sourav
Published: July 2021

Palliative care aims at improving the quality of life of a patient who is suffering from a chronic serious ailment like that of advanced cancer. Nobody wants to be away from his/her own family, especially when it’s known, he has limited days to live in this world. A patient gets the best treatment when it’s given in his own home and that too by his close ones. When palliative care is provided at the patient’s home, it provides a sense of safety, privacy, confidentiality and peace of mind for the patient. Specialist home-based palliative care improves symptom control, health-related communication and psychosocial support. It helps in better preparing the patient and the family members to accept death. It is provided by a team of trained members which includes doctor, nurse, social worker, volunteers, physiotherapist etc. They pay regular visits at the home of the patient and provide necessary health care to the patient. Considering the increasing cost of treatment of chronic illnesses, it’s sometimes hard on the part of the family to continue treatment in a hospital or hospice. It’s especially true in scenarios where population are not protected financially, in countries like India. The family members also play a vital role in home-based palliative care. They get trained from the team to learn the basics of palliation. Home based palliative care needs to be integrated into regular home health care services.
Efficiency of Autologous Egg Cryopreservation: Eight Years’ Experiences and Clinical Outcomes
Authors: T. Wang Cassie , Niu Xiangli , Ruan Qiuyan , Wang Wei-Hua
Published: July 2021

Oocyte cryopreservation is one of the state-of-art technologies in human reproductive medicine, which brings opportunities for women to preserve their fertility. In the present study, we analyzed the efficiency and outcomes of 8 years’ autologous egg cryopreservation: Frozen oocytes were warmed from 120 cycles and oocyte survival, fertilization, blastocyst development, clinical pregnancy, embryo implantation, live birth rates and birth weights were collected based on the patients’ ages of <35, 35–37 and > 37 years old. The details of oocyte cryopreservation and the efficiency were further analyzed based on different patient categories. During the study period, 849 oocytes from 120 cycles were warmed. Oocyte survival, fertilization, and blastocyst development were not affected by women’s ages at the time of cryopreservation. However, number of patients without blastocyst formation was significantly (P < 0.05) higher in patients >37 years old (31.2%) than that in patients <35 years old (13.1%). Higher live birth rates were observed in patients <35 (51.1%) and 35–37 (46.7%) years old than in patients >37 years old (28.6%) after fresh embryo transfer. Some patients did not have blastocysts mainly due to low fertilization by poor sperm or small number of oocytes warmed. These results indicate that the efficiency of oocyte cryopreservation, evaluated by live birth and embryo implantation rates is affected by women’s age, number of oocytes warmed and sperm quality.
The Just as an Absent Ground in Plato's Cratylus
Authors: Horton Sarah ,   Philosophy Documentation Center
Published: July 2021

Through a study of nature and paternal power, this paper sheds light on the neglected theme of the relation between language and justice in Plato’s Cratylus. The dialogue inquires after the correctness of names, and it turns out that no lineage leads us back to a natural ground of names. Every lineage breaks; nature is always disrupted by the monstrous. It does not follow, however, that names are mere conventions without significance: on the contrary, naming is best understood as a prayer to and for the just. The Cratylus reveals the insufficiency of language not to lead us to despair but to call us to the humility and the hope in which we must pray for justice.
Que conclure de neuf années de suivi sur la population de Vertigo de Des Moulins Vertigo moulinsiana (Dupuy, 1849) ?
Authors: CUCHERAT Xavier , HUBERT Baptiste , VANAPPELGHEM Cédric
Published: July 2021

La présence du Vertigo de Des Moulins Vertigo moulinsiana (Dupuy, 1848) a justifié l’inscription du site du marais de la Grenouillère dans le réseau Natura 2000 et a motivé le suivi de la population de cet escargot inscrit à l’Annexe II de la Directive Habitats-Faune-Flore. Un suivi a été mené pendant neuf ans sur l’espèce à l’aide d’un protocole non-invasif. Les données ont été traitées à l’aide de techniques statistiques adaptées. La fluctuation de l’abondance du Vertigo de Des Moulins est faible à l’échelle du site, mais varie selon les transects. La variabilité des abondances relevées a une incidence sur la précision des estimations et ne permet pas de conclure sur l’état de conservation de l’espèce sur le site. En effet, l’espèce est capable de restaurer ses abondances d’une année sur l’autre, même lorsque les effectifs sont très bas. La recherche de facteurs explicatifs ne permet pas de dire quelle variable mesurée influence le plus l’espèce, dans la mesure où leur significativité change selon les années de suivi. La pertinence du suivi est discutée et des perspectives sont proposées pour pouvoir établir un nouveau protocole adapté.

Unsafe Ground
Authors: Mitchell Jonathan Paul
Published: July 2021

This paper discusses how everyday technologies contribute to the enaction of disability, in particular by continually frustrating the formation of a general sense of ease in the world. It suggests that bodies have a fundamental relationality, within which technology comprises a central aspect; and that the very entity called the human is constituted through relationships with technologies. Then, it considers two ways that the organisation of technology is involved in the realisation of both ability and disability. First, it describes how the distribution of technological resources for activity are centred around bodies that are attributed normality and correctness, which also de-centres bodies falling outside this category: the former are enabled to act while the latter are not. Second, it proposes that ability and disability also involve habit: activities that have not only been repeated until familiar, but in which body and technologies can be forgotten. That typical bodies are centred allows them to develop robust habitual relationships with technological environments in which body and technologies can recede from attention, and crucially, to acquire a sense that their engagements will generally be supported. Atypical bodies, as de-centred, lack this secure ground: they cannot forget their relations with environments, and cannot simply assume that these will support their activity. This erodes bodily confi dence in a world that will support the projects, whether ordinary or innovative, that constitute a life.

Analysing Famine
Authors: Maxwell Daniel , Hailey Peter
Published: July 2021

Famine means destitution, increased severe malnutrition, disease, excess death
and the breakdown of institutions and social norms. Politically, it means a
failure of governance – a failure to provide the most basic of
protections. Because of both its human and political meanings,
‘famine’ can be a shocking term. This is turn makes the analysis
– and especially declaration – of famine a very sensitive subject.
This paper synthesises the findings from six case studies of the analysis of
extreme food insecurity and famine to identify the political constraints to data
collection and analysis, the ways in which these are manifested, and emergent
good practice to manage these influences. The politics of information and
analysis are the most fraught where technical capacity and data quality are the
weakest. Politics will not be eradicated from analysis but can and must be
better managed.
The Critical Risk of Disinformation for Humanitarians – The Case of the MV Aquarius
Authors: Healy Sean , Russell Victoria
Published: July 2021

The search and rescue of refugees, asylum seekers and migrants on the
Mediterranean has become a site of major political contestation in Europe, on
the seas, in parliaments and government offices and in online public opinion.
This article summarises one particular set of controversies, namely, false
claims that the non-government organisations conducting such search and rescue
operations are actively ‘colluding’ with people smugglers to ferry
people into Europe. In spring and summer 2017, these claims of
‘collusion’ emerged from state agencies and from anti-immigration
groups, became viral on social media platforms and rapidly moved into mainstream
media coverage, criminal investigations by prosecutors and the speech and laws
of politicians across the continent. These claims were in turn connected to
far-right conspiracy theories about ‘flooding’ Europe with
‘invaders’. By looking at the experience of one particular ship,
the MV Aquarius, run in partnership by MSF and SOS
Méditerranée, the authors detail the risks that humanitarian
organisations now face from such types of disinformation campaign. If
humanitarian organisations do not prepare themselves against this risk, they
will find themselves in a world turned upside-down, in which their efforts to
help people in distress become evidence of criminal activity.
Quantification and Humanitarianism
Authors: Lawson Brendan T.
Published: July 2021

Over the past 25 years, the humanitarian sector has become increasingly dominated
by numbers. This has been reflected in the growth of academic work that explores
this relationship between humanitarianism and quantification. The most recent
contribution to this literature is Joël Glasman’s
Humanitarianism and the Quantification of Humanitarian
Needs. Through his empirical and theoretical contributions, Glasman
draws our attention to the different ways that academics approach this topic.
These four strands structure the literature review: knowledge – the
technical difficulties in quantifying phenomena; governance – how numbers
help humanitarian organisations manage the sector; effects – the impact
that quantification has had on the sector as a whole; meaning – the
importance of rhetoric, discourse, representation and communication when it
comes to understanding the quantitative. As part of the review, the essay also
identifies how academics can better engage with each of the four strands.

Osobine ličnosti i karakteristični obrasci kriminalnog ponašanja počinitelja ubistva u Republici Srpskoj
Authors: Radetić Lovrić Sanja , Vujadinović Suzana
Published: July 2021

Cilj ovog istraživanja je ispitati da li postoje razlike među počiniteljima ubistva u odnosu na karakteristične obrasce kriminalnog ponašanja i kakva je njihova veza sa osobinama ličnosti počinitelja. Uzorak su činila 74 ispitanika koja su u vrijeme sprovođenja istraživanja bili na odsluženju kazne u Kazneno-popravnim ustanovama u Republici Srpskoj. U istraživanju su primijenjene skale i upitnici procjene zadovoljavajuće istraživačke pouzdanosti. Dobijeni rezultati su pokazali da postoje razlike među počiniteljima u odnosu na karakteristične obrasce kriminalnog ponašanja. Prvi tip ubica ubija vatrenim oružjem, u zatvorenom prostoru, ne planiraju ubistvo, nemaju ranijih osuda niti saučenika prilikom izvršenja krivičnog djela. Drugi tip ubica koristi hladno oružje, ubija na otvorenom prostoru, imaju saučesnike i planiraju zločin. Oni su imali ranijih osuda i to krivična djela protiv imovine i krivična djela protiv javnog reda i mira. Nema statistički značajnih razlika među dva tipa počinitelja u pogledu osobina ličnosti. Dobijeni rezultati istraživanja mogu unaprijediti saznanja u prevenciji pojave kriminala, kao i u resocijalizaciji počinitelja.
Сложеност одрастања савременог дјетета у пјесничкој интерпретацији Драгомира Ђорђевића
Authors: Јовић Слободан
Published: July 2021

Рад се бави сложеношћу одрастања као темом у оквиру поезије Драгомира Ђорђевића, чији пјеснички опус представља један од најзначајнијих пјесничких опуса намијењених дјеци у српској поезији друге половине двадесетог вијека. Ђорђевићева поезија показује изразиту умјетничку свијест о проблемима одрастања дјетета у савременом свијету, што је чини изразито модерном и изазовном за тумачење. Аутор уочава три тематско-мотивска круга у Ђорђевићевој поезији која су повезана са сложеношћу одрастања. Најприје, ту су пјесме у којима лирски субјект пјева о тјелесном кажњавању дјетета, затим о „педагогизацији“ дјетињства, те о емоционално угроженом дјетету. Аутор анализира низ пјесама у којима је опјевано физичко кажњавање дјетета. Физичко кажњавање дјетета присутно је у многим културама, мада оно може бити и ритуалног карактера. У Ђорђевићевим пјесмама физичко кажњавање спроводе одрасли над дјецом са циљем дисциплиновања и покоравања нормама старијих. Васпитање је претворено у једну од многобројних дјелатности која се планира, реализује и вреднује што доводи до развоја и унапређења когниције, али и гушења креативности, маште и игре. Технолошки напредак и конформистички стилови живота довели су до презаузетости родитеља, те од прижељкиваног вијека дјетета имамо вијек професионалаца који се баве дјецом. Издвајање васпитања из животног контекста створило је бројне психолошке тешкоће у одрастању савремене дјеце.

Luces para entender el prohibicionismo: los orígenes sudamericanos de la “guerra contra las drogas”
Authors: Beckmann Nicolas Alexander
Published: July 2021

The present article hopes to contribute to a growing literature that challenges the dominant interpretations of the “war on drugs,” which assume that South America has been merely a recipient and victim of external drug policy models. Through the analysis of official documents, protocols of diplomatic conferences and media reports, the article shows that since the 1970s South American governments promoted and developed prohibitionist drug policies based on their own interests and initiatives. This new contextualization helps understanding why prohibition remains the most important approach to drug policy today, despite its evident failure.
Violencias invisibles hacia mujeres y niñas con discapacidad: elementos que favorecen la continuidad de la práctica de esterilización forzada en Chile
Authors: Yupanqui-Concha Andrea , Aranda-Farias Cristian , Ferrer-Pérez Victoria A.
Published: July 2021

In 2017, Chile was denounced by the United Nations, along with 37 other countries, for the practice of forced sterilizations on women and girls with disabilities. This research explores the views of Chilean activists, professionals, and researchers on the factors that favor the continuation of this practice in the country. Twenty-one informants were interviewed using a qualitative approach based on constructivist grounded theory. The main factors that lead to this type of sterilization were the acceptance of sexual violence and the non-recognition of the violence perpetrated, the absence of a protective state, and the dynamics of abuse of power over women and girls with disabilities. It is concluded that forced sterilization is part of a vast repertoire of violence against women and girls with disabilities, which deepens and perpetuates dynamics of oppression, injustice, and social inequality.

El enfoque de la gestión comunitaria del agua en el Ecuador es un tema de vital importancia. El ejemplo del proyecto Pesillo-Imbabura, en donde la organización comunitaria fue fundamental para su ejecución, dio lugar a esta investigación. Reuniones de dirigentes, asambleas de usuarios, protestas, mingas, diálogo con distintos actores y con la cooperación fueron claves en el desarrollo del proyecto Pesillo: un ejemplo de cómo la unión y un objeto común son claves para tener resultados de desarrollo en territorios indígenas. Esta publicación recoge antecedentes históricos sobre las formas de acceso al agua hasta la creación de las Juntas de Administración de Agua Potable Comunitarias. Analiza tanto el derecho al agua como la organización comunitaria y, en Pesillo, encuentra un ejemplo que visibiliza la lucha por el agua a nivel nacional.
Comparative population genetics of swimming crab host (Portunus pelagicus) and common symbiotic barnacle (Octolasmis angulata) in Vietnam
Authors: Dang Binh Thuy , Truong Oanh Thi , Tran Sang Quang , Glenner Henrik
Published: July 2021

Background

By comparing spatial geographical structures of host populations with that of their symbionts light can be shed on their biological interactions, and the degree of congruence between host and symbiont phylogeographies should reflect their life histories and especially dispersal mechanisms.

Methods

Here, we analyzed the genetic diversity and structure of a host, the blue swimming crab, Portunus pelagicus, and its symbiotic pedunculate barnacle Octolasmis angulata from six location sites representing three geographic regions (north, central and south) along the Vietnam coastline. High levels of congruence in their phylogeographic patterns were expected as they both undergo planktonic larval stages.

Results

Based on the COI mtDNA markers, O. angulata populations showed higher genetic diversity in comparison with their host P. pelagicus (number of haplotype/individuals, haplotype and nucleotide diversity are 119/192, 0.991 ± 0.002 and 0.02; and 89/160, 0.913 ± 0.02 and 0.015, respectively). Pairwise Fst and AMOVA analyses showed a more pronounced population structure in the symbiotic barnacle than in its crab host. The DAPC analyses identified three genetic clusters. However, both haplotype networks and scatter plots supported connectivity of the host and the symbiotic barnacle throughout their distribution range, except for low subdivision of southern population. Isolation by distance were detected only for the symbiont O. angulata (R2 = 0.332, P = 0.05), while dbMEM supported spatial structure of both partners, but only at MEM-1 (Obs. 0.2686, P < 0.01 and Obs. 0.2096, P < 0.01, respectively).
A Study of the Influence of Physical Fitness Management for Fire Fighting Officials on Site Response Ability: The Relationship between Participation Motivation, Exercise Immersion, Exercise Continuation, and Teamwork Improvement
Authors: Kwon Hyeok , Kim Dong Young , Kim Hee Dong , Baek In Hwan
Published: July 2021

As the scale of a disaster increases, many firefighters experience physical limitations. Physical strength and teamwork are of great importance in firefighting, and insufficient physical strength can cause a decline in teamwork during field activities through a decline in the ability to respond. This study analyzed the effect of physical fitness training on teamwork among employees who experienced CrossFit, a fitness training program, and found that the motivation to participate in firefighting CrossFit has an effect on the continuation of exercise. The factors promoting the continuation of exercise include firefighting officials. It was confirmed through hypothesis testing that CrossFit contributed to the improvement of teamwork, suggesting that improving teamwork through physical fitness is the most basic policy to strengthen firefighters’ field response capabilities. In addition, we conducted a survey of the actual condition of each firefighter’s exercise habits, exercise cycles, and preferences for the fitness improvement program and analyzed their physical fitness training to facilitate management program development and system improvement.
Numerical Simulation on Effects of Horizontal Natural Opening Area and Heat Release Rate on Temperature Distribution and Vent Flow in Small Compartment
Authors: Park Min Yeong , Yang Ji Hyun , Lee Chi Young
Published: July 2021

In this study, the numerical simulation to investigate the effects of horizontal natural opening areas and heat release rates on temperature distribution and vent flow in a small compartment was performed using a fire dynamics simulator. The reduced scale model of a stage in a real scale theater with horizontal natural opening was selected for this study. The horizontal opening areas were 0.0196, 0.1024, and 0.2025 m2 (1, 5, and 10% of the floor area, respectively), and the heat release rates were 0.46, 1.35, and 2.61 kW. By decreasing the horizontal opening area and increasing the heat release rate, the temperature in the compartment increased. Additionally, by increasing the heat release rate, the average velocity near the center of the opening increased. For the increase in the horizontal opening area from 0.0196 to 0.1024 m2, the velocity near the center of the opening increased. However, when the horizontal opening area increased from 0.1024 to 0.2025 m2, the variation in velocity was not noticeable. Considering the analyses of temperature and velocity distributions of vent flow, the bidirectional flow pattern was observed, where the outflow and inflow occurred at the center and edge of the horizontal opening, respectively. The mass flow rate through the horizontal opening increased with the increase in the horizontal opening area and heat release rate. The previous correlation for mass flow rate under-predicted the present numerical simulation data.

Published: July 2021

Firefighters are constantly exposed to dangers in disaster sites and they need a plan to safeguard their mental health. There are various programs in place, such as mental and physical health stabilization rooms, to reduce stress and prevent mental illnesses. While these are easily accessible during work, they are lacking in function. To effectively decrease the stress of firefighters, a 65-inch TV set, a healing chair, and an aromatic device were installed in an independent booth, called a healing room. Such rooms were built in fire stations and its effects on stress were analyzed. Five quantitative indicators were identified based on the ECG measurement of firefighters and stress reduction effects were confirmed. Additionally, for the qualitative analysis, mental health interviews of firefighters confirmed stress reduction. The results of this study are expected to be used as baseline data to enhance psychological resilience in firefighters and to revitalize their mental and physical health using stabilization rooms.

This technology includes preparation of a mixture on a separate pad directly on construction object. The possibility of including sand located nearly the construction object into the mixture is analyzed. Major advantages of using GSM during construction of roads using practical experience are reviewed. The condition of the cover during the operation period is shown.
FAILURE TO ACHIEVE PLANNED ECONOMIC PERFORMANCE OF OIL AND GAS PRODUCTION PROJECTS DUE TO LACK OF RISK ASSESSMENT AND UNCERTAINTY QUANTIFICATION
Authors: Nazarenko M.Y. , Zolotukhin A.B.
Published: July 2021

Quantitative assessment of risks and uncertainty has always played the most important role in the evaluation of oil & gas projects. Any estimated, measurable or evaluable magnitude contains an uncertainty, whether it concerns measuring watercut by means of a multiphase flow meter (MPFM) or to the net present value (NPV) of a major E&P project. Evaluation of project economics, e.g. the calculation of net present value (NPV), internal rate of return (IRR), OPEX and CAPEX shall be probabilistic, i.e. carried out with the quantitative assessment of risks and uncertainty of estimated (predicted) values. Nevertheless probabilistic estimate takes place very rarely. Most commonly, assessment of risks and uncertainty would be intuitive or based on a number of deterministic scenarios mistakenly referred to as pessimistic, optimistic and most probable. This research simulates failure to achieve target economic efficiency of E&P projects with no quantitative assessment of risks and uncertainty, and reviews previous international research conducted to identify the effect of ignoring probabilistic estimates related to the evaluation of E&P projects on their final economic efficiency.
THE GEOLOGICAL HISTORY AND RESOURCE POTENTIAL OF OVINPARMIAN CARBONATE RESERVOIRS OF DOLGINSKO-PAPANINSKAYA STRUCTURAL ZONE (Timan-Pechora plate

Published: July 2021

One of the most promising oil and gas areas of the Pechora Sea shelf is the Dolginsko-Papaninskaya structural zone. Commercial hydrocarbon content has been proved by exploration drilling for the Carboniferous – Lower Permian carbonate reservoirs at the southern part of the structural zone (Dolginskoye field). However huge oil and gas potential in this region may also be associated with the Ordovician - Lower Devonian complex. Gazprom Neft is conducting systematic exploration and research projects on the Pechora Sea shelf in order to clarify the geological and geophysical parameters of prospective objects. 3D seismic data provided for the three license blocks demonstrate erosion and hypergene transformation of the Lower Devonian carbonate rocks within the uplifts of the Dolginsko-Papaninskaya structural zone. This transformation is a result of the Middle Devonian restructuring. There are local structures where the Lower Devonian sediments are cut off and the regional Timan-Sargaevsky argillaceous seal rocks overlap the carbonate rocks of the Ovinparmian horizon (Lochkovian stage). Secondary transformation of Ovinparmian sediments (dolomitization, dissolution, fracturing etc.) provide formation of high capacity reservoirs. It is spoken in details about sedimentation models and diagenesis transformation of the Ovinparmian carbonate rocks. Hypergene zones are confidently traced according to the materials of seismic facies analysis. The estimated resource potential of the Lower Devonian prospective objects is comparable to the Carboniferous – Lower Permian carbonate complex. The data on probable analogous fields localized in the adjacent tectonic areas are presented in the paper

Flow cytometric sorting is a vital tool in biological research and clinical diagnostics. Theoretically, a high‐speed jet‐in‐air sorter is a fluorescent‐activated cell sorting sorter that ideally processes cells with high purity, yield, and viability. However, high‐speed jet‐in‐air sorting is a complex process due to its inherent requirements for high fluidic stability and electronic and timing precision. Here, we report that an additional manual correction of drop delay leads to improved cell yield. Adding 2% FBS to the loading buffer had no significant effect on the fate of sorted cells in 4 h. However, the addition of a suitable concentration of FBS/BSA in the collecting buffer resulted in a notable increase in cell count and proliferation and a significant decrease in cell apoptosis for cell lines and primary cells. Moreover, the level of gene expression remained steady in the 5% FBS collecting buffer. In summary, here we demonstrate techniques that can be easily followed to refine sorted yields of healthy cells.

Primary lymphedema results from the anomalous development of the lymphatic system and typically presents during infancy, childhood, or adolescence. Adult‐onset primary lymphedema is rare and mutations associated with this condition have not been identified. The purpose of this investigation was to search for variants that cause adult‐onset primary lymphedema. We discovered an autosomal dominant EPHB4 mutation in a patient who developed unilateral leg lymphedema at age 39 years; the same mutation affected his son who presented with the disease at 14 years of age.

We developed a cyclic amplification method for an organic afterglow nanoreporter for the real‐time visualization of self‐generated reactive oxygen species (ROS). We promoted semiconducting polymer nanoparticles (PFODBT) as a candidate for emitting near‐infrared afterglow luminescence. Introduction of a chemiluminescent substrate (CPPO) into PFODBT (PFODBT@CPPO) resulted in a significant enhancement of afterglow intensity through the dual cyclic amplification pathway involving singlet oxygen (1O2).1O2produced by PFODBT@CPPO induced cancer cell necrosis and promoted the release of damage‐related molecular patterns, thereby evoking immunogenic cell death (ICD)‐associated immune responses through ROS‐based oxidative stress. The afterglow luminescent signals of the nanoreporter were well correlated with light‐driven1O2generation and anti‐cancer efficiency. This imaging strategy provides a non‐invasive tool for predicting the therapeutic outcome that occurs during ROS‐mediated cancer therapy.
Nano cobalt ferrite encapsulated‐silica particles bearing melamine as an easily recyclable catalyst for the synthesis of dihydropyrano[2,3‐c]pyrazoles under green conditions
Authors: Dadaei Mahla , Naeimi Hossein
Published: July 2021

In this research, it was displayed an efficient method for synthesis of 6‐amino‐2,4‐dihydropyrano[2,3‐c] pyrazol‐5‐carbonitrile derivatives by using CoFe2O4 silica supported bearing melamine as a magnetic nanocatalyst. This nanocomposite was prepared in several steps and characterized by XRD, FT‐IR, SEM, EDX, VSM, and TGA techniques. The catalyst has a large active site that has functionalized on the surface of nanostructure. The advantages of this magnetic nanocatalyst are simple achievable, effective heterogeneous nanocatalyst, non‐toxic, small amount of catalyst used, resulted products with high yields and short reaction times, easy work up, and reusability. The central core nanoparticles are excellent chemical and magnetic stability. Therefore, the magnetic moment of cobalt ferrite relaxes much slower than the magnetite with the similar particle size.

Six lignin‐based polyols (LBPs) have been prepared by cationic ring opening polymerization of an oxirane in the presence of an organosolv lignin in tetrahydrofuran (THF) as reaction media and co‐monomer. The prepared LBPs have been characterized and tested for the first time as phase change materials (PCMs) for thermal energy storage (TES) at low temperature. It was found a strong influence of the LBPs composition on their performance to storage thermal energy. Thus, LBPs with higher THF wt% content and lower oxirane/THF mass ratio exhibit the highest latent heats. Furthermore, a clear inversely proportional trend between the oxirane/THF mass ratio and the melting temperatures of the prepared LBPs was noticed. Among the prepared LBPs, the highest obtained latent heat was 53.7 J/g demonstrating the potential application of lignin as feedstock for PCMs preparation. To the best of our knowledge, this is the first time that a biomass derived PCM based on lignin has been studied and considered for TES applications at low temperature. LBPs show energetic solid–liquid transitions that point out their promising potential as bio‐PCMs. This work paves the way to introduce new bio‐based PCMs from lignin in TES systems, for example, in a more sustainable construction sector.

Published: July 2021

Children with autism spectrum disorder (ASD) are at elevated risk for psychiatric problems in response to the COVID‐19 pandemic. This risk is due to their high rates of pre‐pandemic psychiatric comorbidities and the pandemic's disruption to routines and access to necessary supports. Prior research has indicated that children with ASD may experience a worsening of specific psychiatric symptoms in response to COVID‐19, though this body of work is limited in scope. The present study expands this literature by examining specific types of psychiatric problems that emerged about 2 months after the onset of the pandemic, and risk factors predicting changes in these psychiatric symptoms. Parents of children with a confirmed ASD diagnosis (N = 257), who enrolled in a clinic registry at an outpatient specialty autism center, were included in this study. All data were gathered online via customized and standardized questionnaires. Results showed that 59% of children experienced either a worsening of their pre‐pandemic psychiatric diagnoses and/or the development of new psychiatric symptoms during the pandemic. Multivariable regression models indicated that risk factors for increased psychiatric problems included child understanding of COVID‐19, COVID‐19 illness in the family, low family income, and elevated parental depression and anxiety symptoms (all p < 0.05). Findings from this study emphasize the urgent need to provide effective and accessible psychiatric services for children with ASD and their families during and after the pandemic.

Lay summary

Children with ASD are at high risk for psychiatric problems during the COVID‐19 pandemic. We found that 59% of children in our clinical sample are experiencing increased psychiatric problems. The child's understanding of COVID‐19, COVID‐19 illness in the family, low family income, and depression and anxiety symptoms in the parent increase the risk for poor mental health during the pandemic. These findings indicate the importance of helping children with ASD access mental health treatment during COVID‐19.

Published: July 2021

Introduction

The aim of this case series was to assess the feasibility of a graft modification to increase its length when treating multiple adjacent gingival recessions with only one harvesting site at the palate and respecting the safety zone.

Case Series

Nineteen recessions were treated in four consecutive patients with a modified coronally advanced tunnel and a modified connective tissue graft. An 8‐mm height connective tissue graft was harvested by the single‐incision technique, the graft was split longitudinally, achieving 4‐mm height and double the length. Changes in recession depth, keratinized tissue height, mean and complete root coverage, and esthetic score were analyzed at 6 months. The technique allows to harvest a connective tissue graft up to 58‐mm length with a single palatal site. Complete root coverage was achieved in 15/19 recessions (78.94%), with a mean root coverage of 82.90%. The mean recession depth was reduced by 1.31 mm and the keratinized tissue increased by 0.69 mm. The esthetic outcome score was 9.26/10.

Conclusion

This graft modification technique allows increasing significantly the graft length up to 58 mm without any modification of the surgical harvesting procedure. Therefore, it can be suggested to reduce the morbidity.
An examination of personality traits as predictors of electronic word‐of‐mouth diffusion in social networking sites
Authors: Moisescu Ovidiu‐Ioan , Dan Ioana , Gică Oana‐Adriana
Published: July 2021

Nowadays, in the technological era, social networking sites (SNSs) have the capacity to influence, through electronic word‐of‐mouth (eWOM), consumers' attitudes towards brands and companies. Consequently, eWOM via SNSs has become an important marketing communication tool for facilitating consumer interaction, acquiring new customers, and enhancing customer loyalty. However, despite the extensive research conducted to identify and depict the antecedents of eWOM, the prediction of whether and to what extent brand‐related content will be shared on SNSs, based on consumers' personality traits, is still an area of marketing that needs further research. Grounded in the trait theory of personality, the current study's objective is to analyze the impact of SNS users' materialism, narcissism, self‐esteem, and extraversion on eWOM diffusion, both directly and indirectly, mediated by referral visit behavior and knowledge‐based validation. For this, an online survey was conducted among a sample of 301 Romanian Facebook users, data being analyzed using partial least squares structural equation modeling. Our findings reveal a high prevalence of eWOM among SNS users, more than one‐third of the investigated sample having a tendency to pass along information about products and brands in SNSs. The results show that eWOM diffusion in SNSs is positively predicted (directly and indirectly) by users' materialism, extraversion, and narcissism, while the total effect of self‐esteem on eWOM diffusion is insignificant. The research provides useful insights for online marketers, concerning psychographic segmentation and social media communication, as well as for SNS developers, with regard to improving the segmentation and targeting tools offered to online marketers.

The development of chronic kidney disease (CKD) drugs remains a challenge due to the variations in the genes. The vitamin D receptor (VDR) and Cytochrome 24A1 (CYP24A1) genetic variants might affect the drug potency, efficacy and pathway. Here we have to analyse and determine the deleterious single‐nucleotide polymorphisms (nsSNPs) of VDR and CYP24A1 genes and their different population's drug responses in different populations to understand the key role in CKD. Among that the large scale of nsSNP, we used certain computational tools that predicted six missense variants are observed to be significantly damaging effect and SNP variability with large differences in various populations. Molecular docking studies were carried out by clinical and our screened compounds to VDR and CYP24A1. Docking results revealed all the compounds have a good binding affinity (Score). The screened compounds (TCM_2868 and UNPD_141613) show good binding affinity when compared to known compounds. The QM/MM study revealed that the compounds have electron transfer ability and act as a donor/acceptor to mutated proteins. The structural and conformational changes of protein complexes were analysed by molecular dynamics study. Hence, this study helps to identify suitable drugs through drug discovery in CKD treatment. The abovementioned compounds have more binding affinity, efficacy, and potency of both wild and mutant of VDR and CYP24A1.
