Published: July 2020

Formaldehyde (HCHO), a chemical compound used in the fabrication process of a broad range of household products, is present indoors as an airborne pollutant due to its high volatility caused by its low boiling point ( T = − 19 °C). Miniaturization of analytical systems towards palm-held devices has the potential to provide more efficient and more sensitive tools for real-time monitoring of this hazardous air pollutant. This work presents the initial steps and results of the prototyping process towards on-chip integration of HCHO sensing, based on the Hantzsch reaction coupled to the fluorescence optical sensing methodology. This challenge was divided into two individually addressed problems: (1) efficient airborne HCHO trapping into a microfluidic context and (2) 3,5–diacetyl-1,4-dihydrolutidine (DDL) molecular sensing in low interrogation volumes. Part (2) was addressed in this paper by proposing, fabricating, and testing a fluorescence detection system based on an ultra-low light Complementary metal-oxide-semiconductor (CMOS) image sensor. Two three-layer fluidic cell configurations (quartz–SU-8–quartz and silicon–SU-8–quartz) were tested, with both possessing a 3.5 µL interrogation volume. Finally, the CMOS-based fluorescence system proved the capability to detect an initial 10 µg/L formaldehyde concentration fully derivatized into DDL for both the quartz and silicon fluidic cells, but with a higher signal-to-noise ratio (SNR) for the silicon fluidic cell ( S N R s i l i c o n = 6.1 ) when compared to the quartz fluidic cell ( S N R q u a r t z = 4.9 ). The signal intensity enhancement in the silicon fluidic cell was mainly due to the silicon absorption coefficient at the excitation wavelength, a ( λ a b s = 420 nm ) = 5 × 10 4 cm − 1 , which is approximately five times higher than the absorption coefficient at the fluorescence emission wavelength, a ( λ e m = 515 nm ) = 9.25 × 10 3 cm − 1 .

Abstract
Background: Chemical trauma to the cornea is an emergency condition of the eye that requires early diagnosis and good treatment. Alkaline have ability to saponify fatty acids in cells and cell membranes which can make penetration into the stroma and destroy proteoglycans and collagen in cells. Aloe vera (AV) contains several active substances that are reported to have anti-inflammatory, immunomodulatory, and wound healing effects. AV has been reported to accelerate the healing process of corneal epithelial defects by increasing fibroblast proliferation, collagen production and growth factor production. This study aims to determine the difference between the effect of aloe vera extract with a concentration of 10%, 20%, 40% and BSS on the healing of extensive corneal lesions in white wistar rats alkaline trauma models.
Method: This study was an experimental study with a pre and posttest only with control group design in vivo approach to 30 Wistar white rats which were divided into 5 treatment groups for 3 days. Comparative analysis of effectiveness using the ANNOVA test or the Kruskal Wallis test and continued by the post hoc test.
Results: Based on the one way ANOVA test there was a statistically significant difference in effectiveness between the five treatment groups on the percentage of corneal wound healing area and TGF-β expression with an assessment of p = 0,000 each. The administration of alloevera (AV) concentration of 20% had a significant difference in percentage of healing of corneal lesions and TGF-β expression compared with other treatment groups with p = 0,000 each. Large differences in the area of corneal lesions in the 40% AV group were -0.45 in the BBS group, 0.146 in the 10% AV group, 0.493 in the 20% AV group. The difference in the AV group 10% was 0.30 in the BBS group, -064 in the AV group 20%, and -0.14 in the AV group 40%. However, TGFβ expression in the normal control group that did not receive treatment was 54.94 (53.21-56-12). TGFβ levels in the BSS group were 10.44, the 10% aloe vera group was 25.43, 47.99 for the 20% aloe vera group and 37.95 for the 40% aloe vera group.
Conclusion: There is a difference between the effect of aloe vera extract with concentrations of 10%, 20%, 40% and BSS on the extensive healing of corneal lesions in white wistar rats with alkaline chemical trauma models.

Introduction. Abnormalities in the macula is a very significant disorder. One abnormality that can be found is central serous chorioretinopathy (CSC). This case report aims to explain the diagnosis and management of Central Serous Chorioretinopathy.
Case presentation. A 32-year-old man, a soldier, came for treatment at hospital on May 2017. Anamnesis of major complaints right eye blurred since, 1 week before hospitalization. From the investigations, in the right eye, the armsler grid examination showed an impression of metamorphopsia. On examination of the fundus photo, an impression of macular area edema with a clear border is obtained. OCT examination revealed that there was elevation of neuroretina tissue in the macula. This patient was managed by laser photocoagulation at the point of leakage of subretinal fluid.
Conclusion. The diagnosis of central serous chorioretinopathy is made through history taking, ophthalmological examination, and supporting examinations of armsler grid, photo fundus, OCT and FFA. Laser photocoagulation can be performed, especially in cases of persistent, chronic, recurrent, or occupational needs.

AbstractThere has been considerable interest in empirical research on epistemic emotions, i.e., emotions related to knowledge-generating qualities of cognitive tasks and activities such as curiosity, interest, and surprise. One big challenge when studying epistemic emotions is systematically inducting these emotions in restricted experimental settings. The current study created a novel stimulus set called Magic Curiosity Arousing Tricks (MagicCATs): a collection of 166 short magic trick video clips that aim to induce a variety of epistemic emotions. MagicCATs are freely available for research and can be used in a variety of ways to examine epistemic emotions. Rating data also support that the magic tricks elicit a variety of epistemic emotions with sufficient inter-stimulus variability, demonstrating good psychometric properties for their use in psychological experiments.
An Apparent Jump in the Radio Position of J1147+3501
Authors: Titov Oleg , Frey Sándor 
Published: July 2020

Abstract
The fundamental celestial reference frame is realized by observations of extragalactic radio sources using the technique of very long baseline interferometry (VLBI). Compact radio-emitting active galactic nuclei are regularly used as reference points for relative positioning of other radio sources. VLBI absolute astrometric data indicate that the nucleus of the nearby radio galaxy J1147+3501 apparently changed its position by about 0.″02 some time between 1999 and 2017. We suggest that this unusually large displacement is a consequence of a drastic change in the source brightness distribution as revealed by archival high-resolution VLBI images.

Published: July 2020

Permafrost, frozen ground cemented with ice, occupies about a quarter of the Earth’s hard surface and reaches up to 1000 metres depth. Due to constant subzero temperatures, permafrost represents a unique record of past epochs, whenever it comes to accumulated methane, oxygen isotope ratio or stored mummies of animals. Permafrost is also a unique environment where cryptobiotic stages of different microorganisms are trapped and stored alive for up to hundreds of thousands of years. Several protist strains and two giant protist viruses isolated from permafrost cores have been already described.
In this paper, we describe a collection of 35 amoeboid protist strains isolated from the samples of Holocene and Pleistocene permanently frozen sediments. These samples are stored at −18°C in the Soil Cryology Lab, Pushchino, Russia and may be used for further studies and isolation attempts. The collection strains are maintained in liquid media and may be available upon request. The paper also presents a dataset which consists of a table describing the samples and their properties (termed "Sampling events") and a table describing the isolated strains (termed "Occurrences"). The dataset is publicly available through the GBIF portal.

Notre propos est lié à une recherche inter-universitaire débutée en septembre 2016 sur le thème de la gémellité à l’épreuve de la fin d’adolescence et du devenir adulte. Cette recherche est centrée sur la compréhension du jeu entre le même et l'autre des jumeaux monozygotes ; ceux-ci ont inspiré un ensemble de travaux dans la littérature psychanalytique dont nous restituerons les aspects les plus saillants. Nous illustrons la problématique gémellaire par une situation clinique qui pose notamment la question de la différenciation soi/non soi en proposant que, dans ce contexte, la mère peut être un objet symbiotique tiers.
Mottes, manoirs et châteaux : au-delà des inventaires archéologiques, l’exemple du Centre Ouest Bretagne
Authors: Kernévez Patrick 
Published: July 2020

Les mottes médiévales sont souvent présentées comme étant les ancêtres des « châteaux forts » qu’elles auraient précédés aux xie et xiie siècles. Des centaines de mottes ont été recensées dans des inventaires archéologiques en Bretagne : ce chiffre est trop élevé pour faire de toutes celles-ci des « mottes castrales ». On considère désormais que leur fonction fut plus symbolique que militaire : beaucoup n’étaient que les sièges ostentatoires de seigneuries modestes. Le nombre des châteaux médiévaux en Bretagne serait de 250 à 300, bien en deçà de celui des mottes et autres retranchements de terre qui ont pu précéder les milliers de manoirs, édifiés à partir du xiiie siècle. Sur le territoire du Centre Ouest Bretagne, qui s’étend sur 110 communes en lisière des départements du Finistère, des Côtes-d’Armor et du Morbihan, une récente prospection inventaire a estimé à 15 le nombre de châteaux pour 43 mottes, 21 maisons fortes, plusieurs dizaines d’enceintes et d’enclos terroyés médiévaux et environ 400 manoirs, ces derniers datant pour la plupart des xive, xve et xvie siècles.
Entre marée noire et lutte antinucléaire, la position de l’évêque du Finistère
Authors: Le Bot Jean-Michel 
Published: July 2020

La parution en mai 2015 de l’encyclique Laudato Si’ incite à s’intéresser aux prises de position précédentes de l’Église en matière d’écologie. Quelles furent les réactions, localement, face à l’émergence, dans les années 1960 et 1970, de mouvements écologistes ? Dans le Finistère, marqué, à partir du milieu des années 1970, par des luttes écologistes intenses, l’Église ne pouvait pas rester indifférente. Le présent article s’attache plus particulièrement aux prises de position de l’évêque, Monseigneur Barbu, à deux moments clefs de ces luttes : en mars 1978, quelques jours après le naufrage du pétrolier Amoco Cadiz, et en février 1980, dans les premiers jours de l’enquête d’utilité publique pour la construction d’une centrale nucléaire à Plogoff. Ces deux prises de position figurent parmi les toutes premières interventions des responsables de l’Église de France sur le terrain des mobilisations écologistes. Leur contenu et leur réception témoignent des malentendus qui se sont créés dès le départ entre l’Église et les mouvements écologistes naissants.
Drinking water quality and handling practices among women in rural households of Oshimili North Local Government Area of Delta State, Nigeria
Authors: Oloruntoba Elizabeth Omoladun , Olannye Donald Uzowulu 
Published: July 2020

Diarrheal diseases associated with inadequate supply of potable water are the leading causes of mortality among children under five years in developing countries. In Nigeria, women are the water managers in most households. However, there is dearth of information on the effect of women’s handling practices on drinking water quality. Therefore, this study was aimed at assessing the drinking water quality and handling practices among women in selected rural households in Oshimili North Local Government Area of Delta State, Nigeria. Paired drinking water samples from available sources and Household Storage Containers (HSC) were assessed for physico-chemical and bacteriological parameters using standard methods. The data obtained were compared with the WHO guideline limits. Water samples with 0, 1-10, 11-50 and > 50 E. coli/100 mL were graded as A, B, C, and D corresponding to excellent, acceptable, unacceptable, and grossly polluted quality, respectively. Pre-tested semi-structured interviewer-administered questionnaire was used to elicit information from the respondents. A 30-point scale was used to assess water handling practices. Handling practice scores greater or equal to mean handling practice score were grouped into good and those less than that were grouped into bad handling practices. Data were analyzed using descriptive statistics and One-way ANOVA at α = 0.05. The results showed physico-chemical parameters for both sources and households within WHO guideline limits. The mean total coliform counts for all sources and household containers exceeded permissible limits. E. coli was not detected in harvested rain water while counts for borehole was 10.2 ±2.2 (A) and for stream sources was 44.6±33.3 EC/100 mL (B); drinking water stored in HSC had 36.8±32.3 (A) EC/100 mL, borehole had 62.31±33.2 (C) and stream had 30.00±33.2 (B). Mean handling practice score was 19.4+6.6. Majority (60.0%) practiced some water handling technique. Drinking water from assessed sources was of poor microbial quality and it significantly deteriorated when stored in household storage containers. Therefore, there is a need to improve the microbial quality of drinking water at sources and household level through the supply of simple, acceptable, low-cost treatment methods and hygiene education.
Climate Responsive Innovation within the Agricultural Curriculum and Learning System
Authors: Van Staden Wilma 
Published: July 2020

The purpose of this paper is to outline the climate responsive innovation process within the agricultural innovation system of the North West Province, South Africa. The focus was on the embedded curriculum and learning activity system and its responses to social-ecological and earth system changes influenced by climate change. It outlines the barriers and processes hampering curriculum and learning innovations towards climate-smart responsiveness, and also examines the processes required to initiate micro and macro innovations. This paper focusses on how actors within the system can initiate curriculum innovation and climate responsiveness through micro innovations when supported and how this can lead to macro innovations. The system experienced various barriers during the innovation process and overcame many challenges during the journey towards climate-smart responsiveness through the identification of contradictions within the system, developing tools to assist in the transitioning process and expansion in the social-spatial dimension by establishing a learning network within the surrounding communities. The research indicated that the catalysing of the curriculum and learning system required specific tools, time and the understanding of the importance of micro-level innovation. Keywords: curriculum innovation; climate-smart agriculture; agricultural training institutes
EFFECTS OF THE COVID-19 PANDEMIC ON UNIVERSITY PEDAGOGY: STUDENTS' EXPERIENCES AND CONSIDERATIONS
Authors: Kedraka Katerina , Kaltsidis Christos 
Published: July 2020

<p>Due to the coronavirus crisis, universities worldwide have faced sudden pressure to change from face-to-face delivery of courses to digitally enhanced teaching for distance learning. We present a small case study of 75 students from the Department of Molecular Biology and Genetics of the Democritus University of Thrace, Greece on their experiences of the transition from face-to-face to distance learning during this crisis. We used a questionnaire with closed-ended and open-ended questions to record the students’ “fresh” experience of their new educational reality. Students consider distance learning to be interesting, modern, adequate, and convenient, but not able to replace their experience of social interaction with fellow students and teachers. They continue to express worries about lessons, examinations, and laboratory work, which may be due to the specific and high demands of the biosciences. This crisis is an opportunity for universities to improve the use of digital tools for an enhanced learning and teaching experience. This should be supported by investment in digital infrastructure for improving distance learning in higher education.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0622/a.php" alt="Hit counter" /></p>

Abstract. The QA4ECV (Quality Assurance for Essential Climate Variables) version 1.1 stratospheric and tropospheric NO2 vertical column density (VCD) climate data records (CDRs) from the OMI (Ozone Monitoring Instrument) satellite sensor are validated using NDACC (Network for the Detection of Atmospheric Composition Change) zenith-scattered light differential optical absorption spectroscopy (ZSL-DOAS) and multi-axis DOAS (MAX-DOAS) data as a reference. The QA4ECV OMI stratospheric VCDs have a small bias of ∼0.2 Pmolec.cm-2 (5 %–10 %) and a dispersion of 0.2 to 1 Pmolec.cm-2 with respect to the ZSL-DOAS measurements. QA4ECV tropospheric VCD observations from OMI are restricted to near-cloud-free scenes, leading to a negative sampling bias (with respect to the unrestricted scene ensemble) of a few peta molecules per square centimetre (Pmolec.cm-2) up to −10 Pmolec.cm-2 (−40 %) in one extreme high-pollution case. The QA4ECV OMI tropospheric VCD has a negative bias with respect to the MAX-DOAS data (−1 to −4 Pmolec.cm-2), which is a feature also found for the OMI OMNO2 standard data product. The tropospheric VCD discrepancies between satellite measurements and ground-based data greatly exceed the combined measurement uncertainties. Depending on the site, part of the discrepancy can be attributed to a combination of comparison errors (notably horizontal smoothing difference error), measurement/retrieval errors related to clouds and aerosols, and the difference in vertical smoothing and a priori profile assumptions.
The Pronounced Impact of Hip Fractures on Psychosocial Well-being
Authors: Swayambunathan Jay , Dasgupta Abhijit , Bhattacharyya Timothy 
Published: July 2020

Background:
There are little data on the psychosocial well-being of hip fracture patients. Previous studies lacked a control group to isolate the impact of hip fractures from general aging. We sought to overcome these limitations and quantify the impact of hip fractures on psychosocial well-being.

Methods:
We identified a cohort 65 years and older patients who were driving and mobile from the National Health and Aging Trends Study. Participants with exactly one hip fracture between 2011 and 2017 were isolated, and their outcomes an after hip fracture were compared with control subjects via multivariate logistic regression.

Results:
Hip fracture patients reported a notable decrease in driving frequency and mobility in the first year after fracture, along with an increase in depressive symptomatology and decreased participation in activities. Measures of mobility and activities among survivors returned to peer group levels within 2 years. A larger social network was associated with improved outcomes.

Discussion:
Hip fracture survivors experience notable declines in function and well-being in the first year after a hip fracture compared with peers. Although mortality is high, surviving patients experience measurable gains in function and well-being in the 3 years after the fracture. These data aid surgeons in counseling families and patients after hip fracture.

Level of Evidence:
Level I—prognostic study: inception cohort study

Study Design:
Prospective—patients enrolled at a uniform point in course of disease and followed over time
