Photoluminescence properties of shock-modified Tb2O3
Authors: Kishimura Hiroaki 
Published: May 2021

Abstract
The optical properties of Tb2O3 under extreme conditions are of interest because Tb2O3 is widely used for optical devices. In this study, the effect of high-pressure loading on Tb2O3 powder subjected to shock compression was structurally and spectroscopically investigated. The shock-compressed samples were recovered from a high-pressure state to ambient conditions and then characterized by X-ray diffraction analysis, photoluminescence (PL) measurement, and Raman spectroscopy. The onset of the cubic (C-type) to monoclinic (B-type) phase transition of Tb2O3 was confirmed for a sample shocked at 4.3 GPa. The C- and B-type phases coexist between 4.3 and 29 GPa. Changes in the PL excitation PL spectra associated with an increase in yield to the B-type phase were observed. The chromaticity coordinates for the shocked samples indicated that emission color was changed from green to yellowish-green.

Abstract
van der Waals heterostructures (vdWHs) based on atomically two-dimensional materials have gained extensive attention due to their great potential in the new era of next-generation optoelectronics. Most reported photodetectors exhibit type-II band alignment and their photodetection performance is often limited by either low photoresponsivity or high dark current. However, type-Ⅲ vdWHs with broken gaps are still very rare, which limits the development and application of two-dimensional (2D) materials in the fields of photodetector. Here, we demonstrate a highly sensitive black phosphorus (BP)/SnS2 photodetector with type-III (broken-gap) band alignment. The dark current of BP/SnS2 vdWH is greatly suppressed by high barrier at the junction and high photoresponsivity generated from high tunneling current when illuminated. The BP/SnS2 vdWH exhibits both ultrahigh photodetectivity of 6.72 × 1012 Jones and photoresponsivity of 295.3 A W−1 under the illumination of 365 nm light (0.53 mW cm−2). Our results provide an avenue for developing high performance optoelectronics and better understanding the underlying physics in the broken-band alignment systems.
Pękiel według Pękalskiego. Nieznany przekaz „Missa in defectu unius contraaltus” Bartłomieja Pękiela ze zbiorów archiwum krakowskiej kapituły katedralnej
Authors: Bebak Marek 
Published: May 2021

W komunikacie prezentowany jest nieznany przekaz Missae in defectu unius contraaltus Bartłomieja Pękiela, odnaleziony pośród anonimowych rękopisów sporządzonych w XVIII wieku przez Józefa Tadeusza Benedykta Pękalskiego dla kolegium rorantystów katedry krakowskiej. Rękopis o sygnaturze Kk I.26 przechowywany jest w Archiwum Krakowskiej Kapituły Katedralnej. Do tej pory kompozycja Pękiela znana była jedynie ze zdekompletowanego rękopisu wawelskiego Kk I.6 (brakowało najwyższego z trzech głosów). W niniejszym komunikacie zawarto opis manuskryptu Kk I.26 oraz przykłady modyfikacji, jakie wprowadził do swej kopii skryptor. Wśród nich należy wskazać przede wszystkim zwiększenie liczby głosów z trzech (dwa tenory, z czego pierwszy niezachowany, i bas) do sześciu (alt, trzy tenory, z czego jeden mógł być wykonywany ad libitum, ponieważ zdwajał partię tenoru I, bas i basso ripieno, który jest dosłownym powtórzeniem głosu basowego, i w którym podpisany został tekst słowny). Bez podjęcia szczegółowych analiz stylistycznych, nie jest możliwe stwierdzenie, czy któryś z dodanych przez Pękalskiego głosów (alt lub tenor) został skomponowany przez Bartłomieja Pękiela, jednak podjęto już odpowiednie kroki zmierzające do rozwiązania tego problemu badawczego oraz wydania edycji źródłowo-krytycznej kompozycji.

Authors: Stockhammer Kaner Noa , Soudry Ethan , Koren Ilan , Gilony Dror , Avisar Inbal 
Published: May 2021

Purpose:
To report the authors' experience with endoscopic unpowered dacryocystorhinostomy in the treatment of pediatric nasolacrimal duct obstruction, and to evaluate whether surgical site reassessment (after the appropriate healing period) affects clinical outcomes.

Methods:
This retrospective study included 47 children aged between 1.5 and 17.0 years (mean age: 6.9 years) who underwent endoscopic unpowered dacryocystorhinostomy between 2014 and 2019 at one tertiary care hospital. Twenty-six patients required unilateral and 21 required bilateral endoscopic dacryocystorhinostomy. The main outcome measures were duct patency on lacrimal irrigation (“anatomical success”) and resolution of symptoms (“clinical success”) over 6 months of postoperative follow-up.

Results:
Sixty-eight dacryocystorhinostomy procedures were performed. Surgical site reassessment during tube removal was performed in 52 of 68 cases. Five cases (9.6%) required treatment of local pathologies, only after which was symptomatic relief achieved. Overall anatomical success was observed in 49 (94.2%) of the 52 cases in which nasal endoscopy was performed, including the 5 cases treated during reevaluation. Clinical success was observed in 63 (92.6%) cases.

Conclusions:
Pediatric endoscopic dacryocystorhinostomy is an effective surgical procedure used to correct nasolacrimal system obstruction resistant to conservative measures. The unpowered endoscopic dacryocystorhinostomy technique is practical and safe in the pediatric population. Surgical site reassessment allows treating local pathologies threatening ostium patency and increases clinical success rates.

« Ils sont terrifiés par la médecine occidentale »
Authors: Roy Mélissa 
Published: May 2021

Les discours accusatoires sont une dynamique récurrente dans l’histoire des épidémies. Si les études sur le sujet ont tendance à recenser des figures du blâme et montrer en quoi leur accusation renforce des enjeux sociaux préexistants, cette recherche ajoute une perspective complémentaire à ce corpus d’écrits en analysant le travail rhétorique de la production du blâme. À partir du concept de cadres, elle s’intéresse aux logiques argumentatives sous-jacentes aux accusations déployées dans le débat thanatologique lors de l’épidémie Ebola 2013-2016. Notre analyse des commentaires sur Facebook et Twitter indique que cinq cadres accusatoires justifient le déploiement de discours entourant les pratiques funéraires traditionnelles : l’opposition religion – science; l’inaction et l’irresponsabilité; les cultures locales/africaines; la corruption; et la pauvreté. Ces cadres sont appuyés par les autorités sanitaires et les médias, dont les discours sont remis en circulation par les usagers de médias sociaux afin de justifier leurs arguments accusatoires. L’analyse montre que l’usage de ces schèmes et le choix de figures du blâme privilégiées varient selon l’ancrage géographique des usagers de médias sociaux. Une lecture transversale des résultats indique que les cadres accusatoires mobilisent l’« irrationalité » des accusés, et qu’ils ciblent des figures récurrentes, notamment le continent africain et ses habitants. Nous émettons l’hypothèse que ces discours réarticulent des normes et craintes qui vont au-delà de la peur de la maladie et de l’Autre. Ils sont aussi ancrés dans des frustrations préexistantes et réarticulent une préoccupation contemporaine à l’égard de la « désinformation ». En guise de conclusion, nous suggérons des pistes de réflexion pour les stratégies de communication en ligne.
Clinical and Surgical Outcomes of Enneking Stage III Aneurysmal Bone Cysts of the Spine
Authors: Pandey Sanjeev Kumar , Gandham Edmond Jonathan , Prabhu Krishna 
Published: May 2021

Objective:
To study the clinicoradiological characteristics and surgical outcomes in patients with aggressive aneurysmal bone cyst (ABC) of spine.

Materials and Methods:
In this retrospective study, data was collected from patients with aggressive ABC of spine managed between January 2007 and December 2016. Clinical findings, radiological, and histological characteristics were studied. Follow-up was done either in the outpatient clinic or through a telephonic interview.

Results:
Seven patients (mean age, 15.6 years, range, 6–23 years) diagnosed with Enneking stage III aneurysmal bone cyst of the spine were included in the study. Local pain with restriction of movement was the most common presenting complaint (100%). Four patients presented with myelopathy. Thoracic spine was the most common site of involvement (43%). Of the patients, 71% had involvement of all three columns. All patients underwent surgical management; gross total resection in four patients (57%) and subtotal in three patients (43%). Of the seven patients, six required instrumented fusion. None of the patients developed any perioperative complication except for one patient who developed transient hip flexion worsening. Two patients received conformal radiation therapy (RT) postoperatively. The follow-up ranged from 40 months to 108 months (mean follow-up was 4.5 years). There were no recurrences. At last follow-up, all patients were alive and had significant improvement.

Conclusions:
ABC of the spine is found predominantly in the pediatric population. Intralesional en bloc resection with instrumented stabilization provides effective and fast relief from pain, early mobility, good surgical, and long-term outcomes. Conformal RT following a planned subtotal excision prevents the progression of the disease.

Authors: Lampropoulos Charalampos , Markopoulos George , Tsochatzis Stylianos , Bellou Aggeliki , Amanatidis Theofilos , Kehagias Dimitrios , Papadopoulos George , Kehagias Ioannis 
Published: May 2021

Background:
Laparoscopic cholecystectomy (LC) has been associated with an increase in the incidence of biliary and vascular injuries. Pseudoaneurysms (PAs) following LC are rare life-threatening events with limited available experience regarding diagnosis and treatment.

Materials and Methods:
An extensive review of literature during a 26-year period (1994–2020) using MEDLINE® database and Google Scholar® academic search engine revealed 134 patients with at least one symptomatic PA following LC.

Results:
Nearly 81% of patients with PAs become symptomatic during the first 8 weeks following LC. The most common symptoms were gastrointestinal bleeding (74%) and abdominal pain (61%). In 28% of cases, there was a concomitant bile duct injury or leak from the cystic duct stump, whereas in about one-third of cases, PAs presented following an uneventful LC. The most common involved arteries were the right hepatic artery (70%), the cystic artery (19%) or both of them (3%). Trans-arterial embolisation was the favoured first-line treatment with a success rate of 83%. During a median follow-up of 9 months, the mortality rate was 7%.

Conclusion:
Clinicians should be aware of the PA occurrence following LC. Prompt diagnosis and treatment are essential.
New learning area in laparoscopic gastrectomy for gastric cancer
Authors: Yüksel Cemil , Çulcu Serdar 
Published: May 2021

Background:
Laparoscopic gastrectomy cannot be performed routinely in many centres, because there is still no standardisation in the centres where it is performed, and therefore, new learning areas are needed for residents working in these centres for surgical training. These areas are various courses, video training sets and video platforms watched over the internet. The most frequently used platforms are YouTube® and WebSurg®. Our aim is to compare these two online video platforms in terms of laparoscopic gastrectomy and to evaluate the contribution of video platforms to surgical training and whether they have sufficient technical quality.

Materials and Methods:
We made a search on YouTube® and WebSurg® using the keyword 'laparoscopic gastrectomy' on 13 November 2020. A total of 143 videos were analysed, 111 of them on YouTube® and 32 on WebSurg®. All these videos were examined by two surgical oncologists experienced in laparoscopic gastrectomy and using laparoscopy in their daily practice.

Results:
The average video duration was 53.54 min in the YouTube® group and 18.20 min in the WebSurg® group, and this difference was found to be statistically significant between the two groups. According to the LGSS based on surgical procedures, the average score of WebSurg® videos was 10.37 and of YouTube® videos was 5.55, and there was a statistically significant difference between the two groups.

Conclusions:
Today, video platforms have started to play a major role in surgical training. Of these platforms examined, WebSurg® is superior to YouTube® in terms of education and quality, but these platforms still have some deficiencies and need regulation.

Published: May 2021

A study was conducted to assess the microbial safety of ready-to-eat (RTE) foods sold in private and public primary schools in Abeokuta, South-western Nigeria. One hundred and sixty RTE food samples were collected from forty food vendors in thirty primary schools and analysed microbiologically. Socio-economic status and their knowledge of food safety were assessed using the structured questionnaires. Total bacterial counts, total coliform counts and total fungal counts of RTE foods in public primary schools ranged from 6.27 log10cfu/g to 6.47 log10cfu/g, 6.00 log10cfu/g to 6.28 log10cfu/g and 5.85 log10cfu/g to 6.16 log10cfu/g respectively while those of private primary schools ranged from 6.30 log10cfu/g to 7.47 log10cfu/g, 6.15 log10cfu/g to 6.54 log10cfu/g and 5.60 log10cfu/g to 6.70 log10cfu/g respectively. Bacteria isolated from these samples were Bacillus cereus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Proteus spp, Enterobacter aerogenes, Shigella dysenteriae and Escherichia coli while the fungal isolates includeAspergillus niger, Aspergillus fumigatus, Rhizopus spp, Penicillium viridicatum, Mucor spp and Fusarium spp. RTE foods sold in both private and public primary schools were found to be highly contaminated. Inappropriate storage conditions, inadequate knowledge of food safety, attitudes and practices of the food vendors are the factors that may allow the food contamination. These findings demonstrate that ready-to-eat foods vended in public and private primary schools in Abeokuta, South-western Nigeria constitute an hazard to the pupils’ health. Provision of health education to the vendors and enforcing implementation of appropriate hygienic practices would improve food quality.Keywords · Ready-to-eat foods · Microbial safety · Primary schools
The determinants of pottery demand in Ghana
Authors: Nortey S. , Amoanyi R. , Essuman A. 
Published: May 2021

The pottery industry in Ghana has been experiencing low demand for its products due to the influx of plastic products and other substitutes. Empirical studies reveal that consumers prefer these traditional products for their domestic and aesthetic uses. This paper examined the determinants of pottery demand in Ghana. Two pottery centres each in five regions in Ghana in addition to 1421 pottery consumers were randomly selected for the study. Using descriptive statistics under the qualitative and quantitative research designs, the study revealed that price of pottery products and their availability play a very significant role in determining demand. Results on quality and perceived purpose or function of pottery products are however mixed. Keywords: Pottery; demand; determinants; Ghana
