Authors: dela Peña Laurice Beatrice Raphaelle O. , Vejano Mark Raymond A. , Rivera Windell L.
Published: April 2021

Water quality deterioration in source waters poses increased health, environmental, and economic risks. Here, we genotyped Cryptosporidium spp. obtained from water samples of Laguna Lake, Philippines, and its tributaries for the purpose of source-tracking fecal contamination. A total of 104 surface water samples were collected over a 1-year period (March 2018 to April 2019). Detection of Cryptosporidium was carried out using genus-specific primers targeting a fragment of the small subunit (SSU) rRNA gene. The study revealed 8 (14%) tributary samples and 1 (2.77%) lake sample positive for contamination. The species were determined to be C. parvum (n = 4), C. muris (n = 2), C. hominis (n = 1), C. galli (n = 1), C. baileyi (n = 1), C. suis (n = 1), as well as rat genotype IV (n = 1). Two species were detected in duck (C. baileyi) and cattle (C. parvum) fecal samples. The data presented suggest that Cryptosporidium contamination is likely to come from sewage or human feces as well as various agricultural sources (i.e. cattle, swine, and poultry). This information reveals the importance of mitigating fecal pollution in the lake system and minimizing health risks due to exposure to zoonotic Cryptosporidium species.
A Quest to the Therapeutic Arsenal: Novel Strategies to Combat Multidrug-
resistant Bacteria
Authors: Ashwath Priyanka , Sannejal Akhila Dharnappa
Published: April 2021

:

The increasing resistance of the disease-causing pathogens to antimicrobial drugs is a public
health concern and a socio-economic burden. The emergence of multi-drug resistant strains has
made it harder to treat and combat infectious diseases with available conventional antibiotics. There
are currently few effective therapeutic regimens for the successful prevention of infections caused by
drug-resistant microbes. Various alternative strategies used in the recent past to decrease and limit antibiotic
resistance in pathogens include bacteriophages, vaccines, anti-biofilm peptides, and antimicrobial
peptides. However, in this review, we focus on the novel and robust molecular approach of antisense
RNA (asRNA) technology and the clustered regulatory interspaced short palindromic repeat
(CRISPR)-based antibiotic therapy, which can be exploited to selectively eradicate the drug-resistant
bacterial strain in a sequence-specific fashion establishing opportunities in the treatment of multi-drug
resistant related infections.

Authors: Preyde Michèle , Whitworth Katelyn , DiCroce Marco , Markov Anna , Parekh Shrenik , Heintzman John
Published: April 2021

Objective:

The aim for this study was to explore the proportion of
patients with a Substance Use Disorder (SUD), their proportion of overall
admissions, and their psychosocial histories at a regional child and adolescent
inpatient psychiatric unit.

Methods:

A retrospective chart review was conducted on all admissions of patients
with a SUD. Abstracted patient data included demographic information, diagnoses,
psychosocial histories, living situation at the time of admission, legal involvement
and charges, whether an alternate level of care was needed, and discharge plans.

Results:

From September 2018 to February 2020, of the 540 patients admitted, 126
(23.3%) had a SUD recorded in their charts and accounted for 34.6% of the total
number of admissions. Their mean age was 15.85 (SD 1.10; range 13 to 18) years,
and most were identified as female (n=81; 64%), which is consistent with the number
of female patients admitted during the study period (n=366 female of 540 admitted;
X2=0.56, p= 0.45). Common psychiatric diagnoses included mood, trauma, and
stressor-related and anxiety disorders. Most patients (124; 98.4%) had a history of
psychosocial adversity, 90 (71.4%) patients had a parent with a mental illness or a
SUD, 55 (44%) reported being bullied, 54 (43%) reported being sexually assaulted
and several (n=41;33%) had experienced precarious living situations.

Conclusion:

Adolescent inpatients with a SUD were also managing a complex
array of clinical and psychosocial challenges. Upon discharge from the hospital,
some patients were placed on waitlists, and many patients were referred to
specialized treatment far from home, highlighting the need for additional,
comprehensive programs for SUD and the constellation of psychosocial problems
associated with these disorders.

Published: April 2021

The purpose of this paper is to focus on a discussion that discusses Business Model Innovation. Based on preliminary research, the authors develop a proposition whereby the application of BMI in SMEs can be viewed from the degree, typology, and drivers. This paper examines the research published either experimentally, empirically, or conceptually with the theme of Business Model Innovation. The research was obtained from several journal portals such as Emerald Insight, Elsevier, and Research Gate for later criticized. This paper discovers BMI research which is still limited to the realm of large companies as its object, while in the realm of SMEs it is still rarely done. Meanwhile, BMI research at the SME level is expected to be able to boost the performance of SMEs in conducting their business, so that it becomes more structured and can compete in a wider realm. This paper discusses that future research can analyze aspects of innovation, innovation typologies, and factors driving innovation, and further research is expected to add other aspects that might emerge the next day that discuss the context of SMEs in Indonesia.

Authors: Flood-Grady Elizabeth , Solberg Lauren B , Baralt Claire , Meyer Meghan , Stevens Jeff , Krieger Janice L
Published: April 2021

Background

Limited regulatory guidance surrounding the use of social media channels for participant recruitment is an interdisciplinary challenge. Establishing stakeholder-informed procedures is essential for ethical and effective use of social media for participant recruitment.

Objective

This study aims to provide replicable procedures for developing and implementing guidelines for using social media to recruit participants in research studies.

Methods

Social media use cases at the university were used to identify institutional stakeholders for the initiative. After establishing workflow procedures, a scoping review of web-based materials about recruitment and research on the internet and social media from 19 peer institutions and 2 federal agencies was conducted to inform the structure of the policies and procedures. End users (investigators and study coordinators; N=14) also provided feedback on the policies and procedures and implementation.

Results

Representatives (n=7) from 5 institutional offices and 15 subject-matter experts from 5 areas were identified as stakeholders in the development of policies and procedures. Peers with web-based materials (n=16) identified in the scoping review revealed 4 themes that served as a basis for developing our policies and procedures. End user feedback further informed the policies and procedures and implementation. A centrally managed social media account for communicating with participants and hosting advertising campaigns on social media was also established and, when combined with the policies and procedures, resulted in 39 advertising campaigns, and 2846 participants were enrolled in health and clinical research studies.

Conclusions

Our policies and procedures allow research teams to harness the potential of social media to increase study recruitment and participation; the transparent, stakeholder-informed process can be replicated by institutional administrators to establish policies and procedures that meet the interests and needs of their research community.
Perceptions of Mobile Health Apps and Features to Support Psychosocial Well-being Among Frontline Health Care Workers Involved in the COVID-19 Pandemic Response: Qualitative Study
Authors: Yoon Sungwon , Goh Hendra , Nadarajan Gayathri Devi , Sung Sharon , Teo Irene , Lee Jungup , Ong Marcus E H , Graves Nicholas , Teo Tess Lin
Published: April 2021

Background

Frontline health care workers are experiencing a myriad of physical and psychosocial challenges amid the COVID-19 pandemic. There is growing recognition that digital technologies have the potential to improve the well-being of frontline workers. However, there has been limited development of wellness interventions using mobile health (mHealth) technology. More importantly, little research has been conducted on how frontline workers perceive mHealth-based support to promote their well-being.

Objective

This study aimed to explore frontline workers’ experience of conventional psychological wellness programs and their perceptions of the usefulness of mHealth apps and features for promoting well-being. It also sought to identify factors that could potentially influence uptake and retention of an mHealth-based wellness program.

Methods

We conducted semistructured interviews using purposive sampling with frontline workers involved in the COVID-19 response. Various visual materials, collated from existing mHealth app features, were presented to facilitate discussion. Interviews were audio-recorded and transcribed verbatim. Thematic analysis based on grounded theory was undertaken. Themes were subsequently mapped to key nudge strategies—those commonly used for mHealth development—to assess participants’ preferences for particular features and their reasoning.

Results

A total of 42 frontline workers participated in 12 one-on-one interviews or focus group discussions. Frontline workers generally had a limited ability to identify their own psychological problems and liked the reminders functionality of the app to track their mood over time. A personalized goal-setting feature (ie, tailoring) and in-app resources were generally valued, while frequent coaching and messages (ie, framing) were seen as a distraction. The majority of participants desired a built-in chat function with a counselor (ie, guidance) for reasons of accessibility and protection of privacy. Very few participants appreciated a gamification function. Frontline workers commonly reported the need for ongoing social support and desired access to an in-app peer support community (ie, social influence). There were, however, concerns regarding potential risks from virtual peer interactions. Intrinsic motivational factors, mHealth app technicality, and tangible rewards were identified as critical for uptake and retention.

Conclusions

Our study highlights the potential of mHealth apps with relevant features to be used as wellness tools by frontline health care workers. Future work should focus on developing a nonintrusive and personalized mHealth app with in-app counseling, peer support to improve well-being, and tangible and extrinsic rewards to foster continued use.

Authors: Zhang Puhong , Chen Huan , Shang Jie , Ge Jun , Zhang Huichen , Xu Mingjun , Bian Cui , Zhao Yang , Chen Minyuan , Hirst Jane Elizabeth
Published: April 2021

BACKGROUND

Maternal and child health (MCH)–related mobile apps are becoming increasingly popular among pregnant women; however, few apps have demonstrated that they lead to improvements in pregnancy outcomes.

OBJECTIVE

This study aims to investigate the use of MCH apps among pregnant women in China and explore associations with pregnancy outcomes.

METHODS

A retrospective study was conducted at 6 MCH hospitals in northern China. Women who delivered a singleton baby at >28 weeks’ gestation at the study hospitals were sequentially recruited from postnatal wards from October 2017 to January 2018. Information was collected on the women’s self-reported MCH app use during their pregnancy, along with clinical outcomes. Women were categorized as nonusers of MCH apps and users (further divided into intermittent users and continuous users). The primary outcome was a composite adverse pregnancy outcome (CAPO) comprising preterm birth, birth weight <2500 g, birth defects, stillbirth, and neonatal asphyxia. The association between app use and CAPO was explored using multivariable logistic analysis.

RESULTS

The 1850 participants reported using 127 different MCH apps during pregnancy. App use frequency was reported as never, 24.7% (457/1850); intermittent, 47.4% (876/1850); and continuous, 27.9% (517/1850). Among app users, the most common reasons for app use were health education (1393/1393, 100%), self-monitoring (755/1393, 54.2%), and antenatal appointment reminders (602/1393, 43.2%). Nonusers were older, with fewer years of education, lower incomes, and higher parity (P<.01). No association was found between any app use and CAPO (6.8% in nonusers compared with 6.3% in any app users; odds ratio 0.77, 95% CI 0.48-1.25).

CONCLUSIONS

Women in China access a large number of different MCH apps, with social disparities in access and frequency of use. Any app use was not found to be associated with improved pregnancy outcomes, highlighting the need for rigorous development and testing of apps before recommendation for use in clinical settings.

The Durability of Teak Sapwood from Community Forest Treatened by Boron Compound though Lowry-Preservation Method against Subterranean And Dry-Wood Termites
Authors: Pertiwi Yus Andhini Bhekti , Sulistyo Joko
Published: April 2021

Nowadays, most of teak wood that available on the market was mainly from comunity forest. Those teak woods were commonly harvested in the early age. The young teak wood from community forests possesses lower proportion of heartwood than sapwood. Those condition was generally had an affect on the wood durability. Although the wood durability was estimated to be low, but the teak wood from community forest was intensively used for furniture and house construction. Therefore, study on the sapwood durability of young teak wood from community forest is necessary. In the present study, the durability of sapwood treated by boron compound (boric acid and borax) as wood preservatives was investigated. The boron concentrations were 5, 7 and 10%. The vacuum process were used to impreg the preservative into the wood specimens called as Lowry method. The efectivity of preservation method were investigated, namely absorption, retention, penetration, efficacy of subterranean and dry-wood termites. The absorption, retention, and penetration of boron compound were 69.10–96.41 kg/m3, 4.53–5.31 kg/m3, and 3.04–3.16 mm, respectively. Absorption, retention, and penetration of preservatives showed an increasing value by increasing the preservatives concentrations, with the highest values were obtained for 10% boron concentration. Graveyard test was used to evaluate the efficacy of boron in teak sapwood to subterranean termites. During 2 months observation, mass loss and degree of wood damage were 0.42-1.37% and 6.31-18.72%. Furthermore, the efficacy of boron was also conducted for dry-wood termites. The mass loss, degree of wood damage, and dry-wood termites mortality after 28 days observation were 1.46-1.67%, 29.45-32.38%, and 87.33-95.33%, respectively. The durability of boron treatened teak sapwood against subterranean and dry-wood termites was increased. The increasing of teak sapwood durability was characterized by reduction of mass loss and degree of wood damage compared to untreated teak sapwood (control).

Published: April 2021

The dissolution of wood lignin in the alkali solution were analyzed for two fast growing species, sengon (Paraserianthes falcataria) dan leda (Eucalyptus deglupta).  Wood samples were extracted in 1% sodium hydroxide solution in cold and hot temperatures for 24 and 1 h, respectively. Extractable substances content, permanganate consumption (expressed as assumed lignin content) were analyzed from the filtrates, lignin content and diastereomeric of β-O-4 structure were analyzed from the wood residue after alkali extraction. The extracted substances from both of wood in hot alkali was higher than in cold alkali solution, although the time of cold alkali extraction was much longer that hot alkali extraction. Assumed lignin content in the extract was quite high in both samples which were 34.4-42.9% and 35.5-39.8% including 2,15-2,29% dan 1,04-1,32% of lignin for cold and hot alkali extraction, respectively. The changes in stereo isomeric form,  erythro and threo, of β-O-4 structure of lignin in wood residue indicated that partial depolimerization of lignin was takec place during alkali treatment.

Hacia una ética de la mirada: Farocki y las imágenes técnicas
Authors: Bellamy Ortiz Adriana
Published: April 2021

El cine ensayo se ha convertido en uno de los géneros fílmicos más significativos de los últimos años al documentar y reflexionar sobre el papel de los medios de representación audiovisual, su injerencia en la percepción que tenemos del mundo que nos rodea o problematizar la noción de autonomía, autoría, acción, la imagen reencontrada. En este artículo se abordan varias de las características centrales del cine-ensayístico al examinar una de sus obras más importantes: Imágenes y epígrafes de guerra (Bilder der Welt und Inschrift des Krieges, 1989) de Harun Farocki. Se analizan algunos de los motivos formales que expresan de manera puntual la estética de este autor como la relación entre la escritura y el cine, el trabajo dialéctico del montaje, la relación entre la industria bélica y los medios de comunicación.

Hazard assessment of the ongoing lava dome eruption at Popocatépetl volcano from the statistical analysis of significant explosive events in the period of 1997 to 2016.
Authors: Mendoza-Rosas Ana Teresa , De la Cruz-Reyna Servando
Published: April 2021

El volcán Popocatépetl inició un episodio eruptivo en 1994 después de un periodo de 70 años de quietud. Este episodio, que persiste hasta el momento, se caracteriza por una secuencia de episodios sucesivos de emplazamiento y destrucción de domos de lava. Esta actividad va acompañada por la producción de columnas eruptivas de ceniza que alcanzan alturas considerables, tanto en las etapas de formación como de destrucción de los domos. Debido a que la altura de la columna es un indicador de la tasa de liberación de energía de cada evento y de su poder de dispersión y potencial destructivo, utilizamos ese parámetro como indicador del peligro asociado a esa actividad. Por lo tanto, hemos construido una base de datos de las columnas producidas por explosiones significativas que han superado la altura de 4 km sobre la cumbre del volcán en el período de 1997 a 2016. Considerando la ocurrencia de las columnas como una variable aleatoria que representa el peligro de dicha actividad explosiva, analizamos las características estadísticas de esa base de datos. Encontramos que se puede describir la ocurrencia de explosiones significativas como un proceso puntual que se desarrolla en al menos dos etapas, con un punto de cambio significativo en 2003. La primera etapa 1997-2003 tiene un marcado carácter no-estacionario, y se describe bien con una distribución de Mezcla de Exponenciales (MOED), mientras que la segunda, de 2003 a 2016 se comporta de forma estacionaria y se ajusta satisfactoriamente a una distribución exponencial. Esta característica produce diferencias importantes en los resultados de evaluación del peligro de ocurrencia de columnas eruptivas significativas, por lo que es importante analizar continuamente las características estadísticas del proceso para identificar posibles cambios en la dependencia temporal del proceso, que por lo general no van acompañados de manifestaciones físicas evidentes.

Los procesos de caracterización hidrogeoquímica e interacción agua-roca en las subcuencas de Santa Catarina y Ocampo-Paraíso en la Zona Media de San Luis Potosí han permitido identificar los tipos de aguas subterráneas. Los resultados del análisis químico y el estudio geológico regional han permitido documentar los posibles mecanismos de interacción del agua con la roca. Los resultados indican que la composición del agua subterránea en cada una de estas cuencas refleja la disolución por el agua de lluvia de los minerales de carbonato y magnesio de las rocas carbonatadas de la formación del Cretácico (Formación El Abra del Cretácico) y del flujo subterráneo a través de un medio granular con fuerte influencia del material de origen volcánico. Las aguas del tipo Ca-HCO?, Ca-Mg-HCO? se modifican durante el flujo subterráneo mediante la incorporación de iones Na+ y SO?²?. En el caso de la subcuenca III de San Nicolás, se ha documentado que su relleno incluye depósitos fluviales que pueden depositarse en condiciones climáticas de regiones semiáridas. El análisis hidrogeoquímico de las concentraciones de iones mayores, litio y bromo, permitieron identificar que el agua que se extrae de la región es producto de un proceso de mezcla en la que intervienen tres miembros extremos (mezcla ternaria): El primero, Santa Catarina (C?), tiene las concentraciones más bajas de bromo y litio en la recarga ocurre en las partes de mayor altitud en la región, hacia la Sierra de Álvarez. El segundo miembro (C?), tiene valores altos del bromo, bajo en litio y se origina hacia el valle de Ocampo Paraíso. El tercer miembro (C?), tiene bajas concentraciones de bromo, alto en litio y proviene de área de San Nicolás Tolentino. Los porcentajes de mezcla indican que C?, aporta el 50%, C? contribuye con el 31% y C? aporta 19 %, del agua al sistema.

Published: April 2021

El Golfo de México (GoM) es una región oceánica de una dinámica y complejidad particular, que se evidencia en las variaciones espacio temporales de la configuración de sus aguas superficiales. Varios estudios han utilizado las características superficiales térmicas, biológicas o de circulación para proponer subdivisiones estáticas del GoM; sin embargo, ninguna investigación ha regionalizado la zona integrando distintos aspectos oceanográficos de forma dinámica. El objetivo de este trabajo fue proponer una división del GoM que considerara las características físicas y biológicas y que permitiera analizar la evolución mensual espacial de las unidades en un año promedio. Utilizamos análisis multivariados para reconocer la estructura subyacente de los datos, para generar una expresión espacial mensual de los conglomerados y para probar la robustez de los resultados. Se obtuvieron 18 regiones denominadas unidades oceanográficas (UO) que condensan diversas características superficiales del GoM. Se observaron dos grupos de UO: aquellas que están relacionadas con las propiedades de circulación y aquellas que fueron definidas por la asociación de las características biológicas y térmicas. Quince UO están presentes a lo largo del año, mientras que dos tienen presencia únicamente en verano. Todas las UO tienen variaciones temporales tanto en sus características biofísicas como en su expresión espacial. Este estudio propone una manera novedosa de particionar un sistema marino y aporta parámetros cuantitativos interpretables de las UO propuestas. La representación de la variabilidad de unidades oceanográficas homogéneas provee información valiosa para el manejo diferenciado de recursos marinos asociados temporalmente a masas de agua especificas. Los resultados obtenidos proveen también bases robustas para analizar de manera condensada la dinámica de largo plazo de un sistema tan complejo como es el GoM.

La sismicidad en la placa de Cocos subducida por debajo de México central, definida por sismos moderados y grandes, cesa antes de al frente volcánico activo. No se ha localizado algún sismo intraplaca por debajo de los volcanes Nevado de Toluca y Popocatépetl. En este trabajo se reporta un evento de Mw3.3 a una profundidad de 98 km, a 38 km al oeste del Nevado de Toluca. Este evento provee evidencia, por primera vez, de un sismo en la placa subducida a profundidad de ~100 km por debajo del volcán. Registros de este evento también proveen evidencia de una alta atenución de las ondas de cizalla conforme se propagan a través de la cuña del manto astenosférico. Es posible que la sismicidad intraplaca por debajo de los volcanes activos en México central, a un nivel de M ~3, sea abundante pero que no ha sido documentada en el pasado por la falta de instrumentación en la región.
A Probabilistic Model to Quantify the Quality of Open Water Bodies
Authors: Lira Jorge
Published: April 2021

Se desarrolló un modelo para cuantificar la calidad de los cuerpos de agua abiertos sobre la base de la lógica probabilística multivariada. El modelo se basa en parámetros de calidad del agua que ya habían sido reportados en la literatura, tales como: turbidez, clorofila-a, índice de vegetación y usos de la temperatura superficial derivadas de la distribución de valores de píxeles de los parámetros. Dichas funciones se combinaron mediante la lógica probabilística multivariada que produjo un mapa de niveles de calidad del agua. Posteriormente, el modelo se aplicó a los humedales Centla, ubicados en el sureste de México. En ellos pueden observarse numerosos cuerpos de agua en niveles de eutrofización variables. Para probar el modelo propuesto, se desarrollaron ejemplos usando una imagen Terra/Aster. Además, se propuso una escala cualitativa de grados de calidad del agua.

Published: April 2021

Coffee seeds are classified into intermediate seeds which require high moisture content during the storage and possess a short shelf life. Seed germination testing aims to determine the potential of a seed lot, evaluate seed quality during the storage and also to estimate the success of seedling in the nursery. This experiment aimed to determine the germination performance of several Arabica coffee varieties after being stored for six months at controlled temperature. Nine varieties of Arabica coffee, namely Abesinia-3, Andungsari-1, BLP, Gayo-2, Goiaba, Kartika-1, Kayumas, MP-3, and S-795 were used in this study. The seeds were harvested in the 2019 harvest season (September) and the germination was tested in April 2020. The germination test was carried out in laboratory by using petridish. The result showed that the tested Arabica coffee seeds still had a high germination percentage which was more than 85%. Only three varieties namely S-795, Abesinia-3, and Goiaba had low germination growth (<80%). Meanwhile, Kayumas, BLP, and Kartika-1 coffee varieties had the best germination growth with an average length of 34.19 mm; 39.79 mm and 39.41 mm, respectively. Kartika-1 variety needs 6–7 days to germinate; Kayumas, BLP, and Goiaba varieties took 7–8 days; S-795 and MP-3 took 10 days; as well as Andungsari-1, Abesinia-3, and Gayo-2 which took 10–12 days. Arabica coffee seeds that had a short germination time will had a high germination rate and otherwise. Each variety displayed a different germination performance. BLP, Kartika-1, Gayo-2 and MP-3 varieties had high potential germination, 86.67%; 89.17%; 86.67%, and 93.33%, respectively. Kayumas, BLP, and Kartika-1 varieties showed significantly longer germination, namely 34.19 mm; 39.79 mm and 39.41 mm, respectively. The fastest of average germination time was possessed by Kartika-1 variety (6.54 days) and the highest seed germination rate was also possessed by Kartika-1 variety (0.153 per day).

Resource theories of multi-time processes: A window into quantum non-Markovianity

We investigate the conditions under which an uncontrollable background processes may be harnessed by an agent to perform a task that would otherwise be impossible within their operational framework. This situation can be understood from the perspective of resource theory: rather than harnessing 'useful' quantum states to perform tasks, we propose a resource theory of quantum processes across multiple points in time. Uncontrollable background processes fulfil the role of resources, and a new set of objects called superprocesses, corresponding to operationally implementable control of the system undergoing the process, constitute the transformations between them. After formally introducing a framework for deriving resource theories of multi-time processes, we present a hierarchy of examples induced by restricting quantum or classical communication within the superprocess — corresponding to a client-server scenario. The resulting nine resource theories have different notions of quantum or classical memory as the determinant of their utility. Furthermore, one of these theories has a strict correspondence between non-useful processes and those that are Markovian and, therefore, could be said to be a true 'quantum resource theory of non-Markovianity'.

Introduction: To ensure that instructions on oral health for children are administered assertively, you must know the level of knowledge about children’s oral health of parents/caregivers. Objective: Assess the knowledge of parents/ caregivers about healthy hygiene and diet habits in childhood. Materials and Methods: This is a cross-sectional observational study. A structured questionnaire was applied to parents/caregivers containing identification data and 10 questions for the theme. Descriptive analysis was performed on the data obtained. Results: It included a sample of 86 parents/caregivers of schoolchildren from two public schools in Minas Gerais. Most participants have already received information about the importance of oral health and healthy eating (93%) as well as agreeing that primary teeth should be brushed every day (91.9%). All participants found this information important for maintaining children’s oral health (100%). The amount of fluoride dentifrice less than half the length of the toothbrush bristles was recommended by 23.3% of the participants, 15.3% answered that dental floss should be used during children’s oral hygiene. A total of 40.7% believe that the child’s intake of sugary foods interferes with the development of caries. Conclusion: Although most of the participants have already received information about the importance of oral hygiene and healthy eating, and everyone thinks this information is important for maintaining the oral health of children, some questions on the subject are not yet known to most parents/caregivers.

In the light of the current climate crisis, one of the most serious
ecological threats is the increase of desertification. In this context,
restoration projects are necessary for reverting land degradation, and
nature-based solutions could help them. The Cocoon™ has been designed as
a new ecotechnology for improving seedling establishment. The Cocoon
consists of a donut-shaped container made out of recycled cardboard that
provides water and shelter to the seedling, at least during its first
year, which is the most critical for plant establishment. The Cocoon was
tested on a variety of soils, Mediterranean mesoclimates, vegetation and
land uses that allowed testing the effectiveness of this ecotechnology
under different conditions. Six planting trials, five of them in Spain
(Canary Islands, Almería, Catalonia and two in Valencia), and one in
Ptolemais (Greece), were performed. With the objective of studying its
functionality, the survival of the seedlings, their vigor and growth
were monitored along two years. In general, the Cocoon has proven its
effectiveness by increasing seedling survival compared to the
conventional planting system, especially under dry growing conditions
(low rainfall, soils with low water holding capacity). The Cocoon also
allowed for higher growth of some species (olive trees, olm oaks and
Aleppo pines). Moreover, a positive correlation between the rainfall on
the site and the degradation degree of the Cocoon device was observed.
Overall, the Cocoon becomes more efficient the more arid the climate or
the more difficult the growing conditions are.

Vasovasostomie robot assistée : résultats sur le spermogramme post-opératoire à 3 mois & la fécondité secondaire à propos de 4 cas
Authors: Charles Thomas
Published: April 2021

Objective: Evaluation of the efficacy of robotic vasovasostomy
post-vasectomy.

Patients and methods: We present a retrospective study of four
patients aged from 36 to 51 years, who were operated of a vasovasostomy
between September 2007 to July 2009. The same surgeon performed a
robotic-assisted vasovasostomy, bilateral for three of them and only
left unilateral for the last patient who underwent orchidectomy for
right testicular seminoma. These patients had a preoperative semen
analysis confirmed the absence of sperm after vasectomy. All patients
had an outcome of spermatozoa on testicular deferens side in
per-operative. The permeability of the distal vas deferens was
systematically checked. The success criterion was the presence of
spermatozoa in semen control three months. The paternity post
vasovasostomy without medically assisted procreation due to father
sterility was a secondary endpoint.

Results: Four patients had between 0.6 and 27 million sperm per
mL in postoperative semen analysis. Three to seventeenth months after
the vasovasostomy, the wives of four patients have started a pregnancy
between.

Conclusion: The robotic vasovasostomy surgery is a technique
that enabled this small group of patients having good results in regard
to deferential recanalization and to recovery of secondary spontaneous
fertility. A larger cohort needs to be evaluated. The medical and
economical aspects of this method should be compared to those of usual
technics, in vitro fertilization (IVF) and intracytoplasmic sperm
injection (ICSI).
Cell Model for the Scale-up of Fluid Dynamics and Mass Transfer in Random Packed Columns Affected by Maldistribution
Authors: Brinkmann Jost , Merkel Amelie , Plate Dominik , Gruenewald Marcus
Published: April 2021

The characterization of fluid dynamics and mass transfer is often
influenced by phase maldistribution. An existing cell model approach for
fluid distribution is extended for gas distribution and mass transfer.
The model differentiates wall and bulk zones, allowing a detailed
evaluation of local fluid dynamics and mass transfer, which is based on
a state-of-the-art literature correlation. Distribution parameters are
determined experimentally. The model allows scale-up by considering the
phase distribution at constant computational effort. A scale-up strategy
to adapt the distribution parameters to different geometries is
presented. Results for fluid dynamics and liquid distribution are in
good agreement with experimental data of columns with diameters of
0.288, 0.5 and 0.6 m. Mass transfer is in good qualitative agreement
with own experiments in a 0.288 diameter column. While maldistribution
consequently reduces the gas side mass transfer, the reduced liquid bulk
flow weakens the effect of liquid side mass transfer.

The article analyses the impact of natural environment on the creation of a Christian church design, as an example, reviews the Orthodox architecture of Ukraine – historical and contemporary one. From time immemorial, Orthodox churches were erected in the most picturesque places – on high hills, steep banks, near rivers and lakes – so that the temple was reflected in the water surface. A typical example is the historical silhouette of the steep right bank of Kyiv, formed by many churches, cathedrals and monasteries located along the edge of the hilly shore. If temples in the urban environment were constrained by the conditions of dense quarterly development (the principal cathedrals and monasteries were an exception), then the peculiarity of the remote suburban monasteries – the hermitages – was precisely the creation of nature and architecture picturesque combination. At the monasteries, parks, gardens and flower beds were created, artificial lakes were arranged. During the domination of the atheistic ideology, temple construction was in decline, most of the cathedrals, churches and monasteries were destroyed or redesigned under the socialist functions of clubs, museums of atheism, schools and storages. The contemporary course in the creation of new Orthodox churches is aimed at restoring the lost sequence in the church building. In this case, particular attention is paid to the natural environment: churches are built in park areas, in forest parks, on the banks of lakes, surrounded by flower beds. The relevance of the study is explained by the presence in Ukraine of a large number of Orthodox churches – both architectural monuments and newly built, which are traditionally surrounded by gardens, parks and flower gardens as symbols of their non-earthly purpose, the image of the Garden of Eden. Therefore, during the restoration and new construction of such objects, it is necessary to understand the features of the сhurch landscape design, which has been formed and improved over the centuries.
