ANALEMMA AND THE BEGINNING OF MAGHRIB PRAYER ALTERATION (Correlation Of Analemma’s Position Towards The Beginning Of Maghrib Prayer According To Ephemeris Calculation)
Authors: Ni'am M. Ihtirozun , Suraya Khabib 
Published: May 2021

Analemmaa is a change of sun’s position which is inconstant when it is observed in certain time and place during a year period. If the change is served as a diagram, it will shape like ‘eight’ number. The beginning of maghrib prayer during a year period is dyanmic at certain time, and it will change due to alteration of sunset. Therefore, this research aimed to understand the correlation between analemma and the alteration of maghrib prayer schedule. The research uses field research method, which collecting the average of observation data of Sun’s position at the certain time and place during a year period by employing qualitative method. The research found that the alteration of the beginning of maghrib prayer is caused by the analemma’s phenomenon. When the gap between the result of analema’s time observed with maghrib schedule is increased, so the beginning of maghrib prayer is delayed. Yet, when the gap between the result of analema’s time observed with maghrib schedule is decreased, so the beginning of maghrib prayer is sooner.
Comparative study of acid mine drainage using different neutralization methods
Authors: Huang Zhong-sheng , Yang Tian-zu 
Published: May 2021

Abstract
Two-stage acid mine drainage (AMD) neutralization residue yield is 2.57 t/t acid equivalent using limestone and lime, 15.74% less than the 3.05 t/t acid equivalent yield from single-stage lime neutralization residue. XRD results shows that the main residue component generated by two-stage neutralization is CaSO4•0.5H2O, with a molecular weight 15.70% lower than the CaSO4•2H2O generated in single-stage neutralization. The differing amount of gypsum crystallization water from the different neutralization processes is the main cause of the different residue yields. While the actual removal rate and pH of Fe3+ are consistent with the theory, those for Zn2+, Cu2+ and Al3+ are inconsistent with the theoretical values, the error rate increasing with increasing pH. Co-precipitation with and adsorption by Fe(OH)3, mainly generated during neutralization, are the main reasons for the difference. The cost of two-stage neutralization is 16.60% less than that of single-stage neutralization when the initial reaction pH is 3.4, but the unit cost begins to increase if the initial reaction pH is raised above 3.4. When the initial pH is 4.0, the cost of two-stage neutralization exceeds that of single-stage neutralization by 4.07%.

Published: May 2021

Abstract
The collection, evaluation and listing of all available data related to the supply, collection and disposal of water is a project of combining and recording all the data for infrastructure projects and their structure within the urban structure of Alexandria and the wider region, as it was discovered and studied to this day. The paper is a description of the most important storage structures for the waters of the Nile River and the rain. Composing data from previous descriptions, archaeological excavations and random discoveries during construction work created a database. This database currently has 144 tanks of 1 to 4 levels, from 6 m3 to 2,500 m3. In particular, they have identified 27 tanks on 1 level, 50 tanks on 2 levels, 49 tanks on 3 levels, 9 tanks on 4 levels and 9 tanks whose exact morphology is unknown to us. The examples of reservoir technologies and management practices given in this work may be of some importance to the sustainability of water resources for the present and the future. Reservoirs have been used to store both rainwater and spring and river water to meet the needs of seasonal variations. The tanks range from simple to large underground structures. Then, a comparison is made with the water management systems in the wider Mediterranean region and especially in Istanbul, where there is such infrastructure.

Authors: Maddison Ralph , Jiang Yannan , Stewart Ralph , Scott Tony , Kerr Andrew , Whittaker Robyn , Benatar Jocelyn , Rolleston Anna , Estabrooks Paul , Dale Leila 
Published: May 2021

Background
Mobile health technologies have the potential to improve the reach and delivery of interventions for promoting long-term secondary prevention of coronary heart disease.

Objective
This study aims to determine the effectiveness of an SMS text messaging intervention (Text4HeartII) for improving adherence to medication and lifestyle changes over and above usual care in people with coronary heart disease at 24 and 52 weeks.

Methods
A two-arm, parallel, randomized controlled trial was conducted in New Zealand. Participants with a recent acute coronary syndrome were randomized to receive usual cardiac services alone (control, n=153) or a 24-week SMS text message program for supporting self-management plus usual cardiac services (n=153). The primary outcome was adherence to medication at 24 weeks, defined as a medication possession ratio of 80% or more for aspirin, statin, and antihypertensive therapy. Secondary outcomes included medication possession ratio at 52 weeks, self-reported medication adherence, adherence to healthy lifestyle behaviors, and health-related quality of life at 24 and 52 weeks.

Results
Participants were predominantly male (113/306, 80.3%) and European New Zealanders (210/306, 68.6%), with a mean age of 61 years (SD 11 years). Groups were comparable at baseline. National hospitalization and pharmacy dispensing records
were available for all participants; 92% (282/306, 92.1%) of participants completed a 24-week questionnaire and 95.1% (291/306) of participants completed a 52-week questionnaire. Adherence with 3 medication classes were lower in the intervention group than in the control group (87/153, 56.8% vs 105/153, 68.6%, odds ratio 0.60, 95% CI 0.38-0.96; P=.03) and 52 weeks (104/153, 67.9% vs 83/153, 54.2%; odds ratio 0.56, 95% CI 0.35-0.89; P=.01). Self-reported medication adherence scores showed the same trend at 52 weeks (mean difference 0.3; 95% CI 0.01-0.59; P=.04). Moreover, self-reported adherence to health-related behaviors was similar between groups.

Conclusions
Text4HeartII did not improve dispensed medication or adherence to a favorable lifestyle over and above usual care. This finding contrasts with previous studies and highlights that the benefits of text interventions may depend on the context in which they are used.

Remote Teaching in a Preclinical Phantom Course in Operative Dentistry During the COVID-19 Pandemic: Observational Case Study
Authors: Kanzow Philipp , Krantz-Schäfers Christiane , Hülsmann Michael 
Published: May 2021

Background
During the acute COVID-19 pandemic, physical access to the University Medical Center Göttingen was restricted for students. For the first time at our dental school, theoretical knowledge was imparted to students via asynchronous online screencasts and discussed via synchronous video meetings only.

Objective
We aimed to assess the acceptance and effectiveness of distance education as a new teaching format for theoretical knowledge within the preclinical course in Operative Dentistry (sixth semester of the undergraduate dental curriculum in Germany).

Methods
The phantom course comprised distance education (first phase, 11 weeks) and subsequent on-site practical demonstrations and training (second phase, 10 weeks). All theoretical knowledge was taught via online screencasts during distance education (except for the first week, 3 screencasts were uploaded per week resulting in a total of 30 screencasts). Until the end of the term, all students (N=33) were able to view the screencasts for an unlimited number of times. Theoretical knowledge was assessed in a summative examination after practical on-site teaching. Acceptance and effectiveness of the new curriculum and distance education were also measured based on an evaluation survey and students’ self-perceived learning outcome, which was compared to the outcome from the two pre–COVID-19 terms.

Results
Each screencast was viewed by a mean of 24 (SD 3.3) students and accessed a mean of 5.6 (SD 1.2) times per user (ie, by students who accessed the respective screencast at least once). During distance education, the number of accesses showed a linear trend over time. During the practical training phase, screencast views declined and increased again prior to the examination. Screencasts covering topics in Cariology, Restorative Dentistry, and Preventive Dentistry were viewed by more students than screencasts covering topics in Endodontology or Periodontology (both P=.047). Examination items in Periodontology showed inferior results compared to the other topics (P<.001). Within the different topics, students’ self-perceived learning outcome did not differ from that during the pre–COVID-19 terms. Although most students agreed that the presented screencasts contributed to their learning outcome, pre–COVID-19 term students more strongly felt that lectures significantly contributed to their learning outcome (P=.03).

Conclusions
Screencasts showed high acceptance and effectiveness among the students but were not used as a learning tool by all students. However, students who viewed the screencasts accessed each screencast more frequently than they could have attended a conventional lecture. Screencast views were mostly due to intrinsic motivation.

Authors: Liu Jialin , Liu Siru , Zheng Tao , Bi Yongdong 
Published: May 2021

Background
Generalized restriction of movement due to the COVID-19 pandemic, together with unprecedented pressure on the health system, has disrupted routine care for non–COVID-19 patients. Telemedicine should be vigorously promoted to reduce the risk of infections and to offer medical assistance to restricted patients.

Objective
The purpose of this study was to understand physicians’ attitudes toward and perspectives of telemedicine during and after the COVID-19 pandemic, in order to provide support for better implementation of telemedicine.

Methods
We surveyed all physicians (N=148), from October 17 to 25, 2020, who attended the clinical informatics PhD program at West China Medical School, Sichuan University, China. The physicians came from 57 hospitals in 16 provinces (ie, municipalities) across China, 54 of which are 3A-level hospitals, two are 3B-level hospitals, and one is a 2A-level hospital.

Results
Among 148 physicians, a survey response rate of 87.2% (129/148) was attained. The average age of the respondents was 35.6 (SD 3.9) years (range 23-48 years) and 67 out of 129 respondents (51.9%) were female. The respondents come from 37 clinical specialties in 55 hospitals located in 14 provinces (ie, municipalities) across Eastern, Central, and Western China. A total of 94.6% (122/129) of respondents’ hospitals had adopted a telemedicine system; however, 34.1% (44/129) of the physicians had never used a telemedicine system and only 9.3% (12/129) used one frequently (≥1 time/week). A total of 91.5% (118/129) and 88.4% (114/129) of physicians were willing to use telemedicine during and after the COVID-19 pandemic, respectively. Physicians considered the inability to examine patients in person to be the biggest concern (101/129, 78.3%) and the biggest barrier (76/129, 58.9%) to implementing telemedicine.

Conclusions
Telemedicine is not yet universally available for all health care needs and has not been used frequently by physicians in this study. However, the willingness of physicians to use telemedicine was high. Telemedicine still has many problems to overcome.

Published: May 2021

Objective: The objective of this study was to evaluate the effect of a pharmacist-led intervention on self-management practices among hypertensive-diabetic patients receiving care in a Nigeria tertiary hospital.
Methods: The study adopted a prospective, longitudinal; single-blind, two-arm randomised controlled trial to implement a pharmacist-led educational intervention on hypertension management among patients in Federal Medical Centre Lokoja, Kogi State. All the patients who met the eligibility criteria and gave their written consent to participate in the study were recruited into the study randomized in the intervention group (IG) and Control (CG). Data was collected using Hypertension Self Care Activity Level Effects (H-SCALE) questionnaire. The retrieved questionnaires were first coded into Microsoft Excel (2014) for cleaning of errors, after which the data was exported into the Statistical Product and Services Solutions (SPSS for windows, Version 16.0. SPSS Inc. 2007, Chicago, USA) software. Descriptive statistics such as frequencies, percentages and mean scores were used to summarise the data. All responses were first presented as frequencies and percentages. Chi-square was used to determine the correlation between socio-demographic and patients’ clinical characteristics. Independent sample t-test and paired sample t-test were used to compare differences between and within groups.
Results: At baseline, more patients in the control group were adherent to their medications 16 (11.5) and had low salt diets 47 (33.8) than patients in the intervention group. However, more patients in the intervention group were non-smokers 127 (88.8) and engaged more in physical activity 38 (26.6) than patients in the control group. However, more of the patients in the control group were adherent to weight management practices 38 (27.3) than patients in the intervention group 36 (25.2), at baseline. All the patients in both study groups reported to have taken alcohol in the past seven days. It can be seen that, patients in the intervention group at endpoint, differed positively from the control group at baseline in adherence to medication, physical activity, reducing alcohol consumption and smoking cessation. It can also be observed that the baseline intervention group differed positively from the endpoint in medication adherence (t=-26.045, p<0.001); physical activity (t=-15.081, p<0.001); weight management practices (t=-5.479, p<0.0010, and alcohol consumption 9t=-11.550, p<0.001).
Conclusion: A pharmacist led educational intervention had a positive impact on the self-management practices of hypertensive-diabetes patients.
OPTIMIZATION AND CHARACTERIZATION OF DOXORUBICIN LOADED SOLID LIPID NANOSUSPENSION FOR NOSE TO BRAIN DELIVERY USING DESIGN EXPERT SOFTWARE
Authors: SHAH VIRAG A. , PATEL JAYVADAN K. 
Published: May 2021

Objective: The goal of the current study was to investigate the possible use of solid lipid nanosuspension (SLNs) as a drug delivery method to boost doxorubicin (DOX) brain-targeting performance after intranasal (i. n.) administration.
Methods: 33 factorial design was applied for optimization by using lipid concentration, surfactant concentration, and High-speed homogenizer (HSH) stirring time as dependent variables, and their effect was observed on particles size, Polydispersity index (PDI), and entrapment efficiency.
Results: With the composition of Compritol® 888 ATO (4.6 % w/v), tween 80 (1.9 % w/v), and HSH stirring time, the optimized formula DOX-SLNs prepared (10 min). Particle size, PDI, zeta potential, entrapment efficiency, percent in vitro release were found to be 167.47±6.09 nm, 0.23±0.02, 24.1 mV, 75.3±2.79, and 89.35±3.27 percent in 24 h, respectively, for optimized formulation (V-O). No major changes in particle size, zeta potential, and entrapping efficiency were found in the stability studies at 4±2 °C (refrigerator) and 25±2 °C/60±5% RH up to 3 mo.
Conclusion: Following the non-invasive nose-to-brain drug delivery, which is a promising therapeutic strategy, the positive findings confirmed the current optimized DOX-loaded SLNs formulation.
The aporetic financialisation of insurance liabilities: Reserving under Solvency II
Authors: Fytros Charalampos 
Published: May 2021

AbstractThe valuation of insurance liabilities has traditionally been dealt with by actuaries, who closely monitored underlying illiquid features, assumed a long-term perspective, and exercised their own subjective, expert judgment. However, the new EU regulatory regime of Solvency II (S2) has come to require market-consistent valuation supplemented by a risk-sensitive capital. This is considered an unwanted shift towards short-termism that is misaligned with the industry's long term and countercyclical character. The new principles place the ‘technicalising’ logic of financial economics over ‘contextualising’ actuarial know-how. Following existing analytics of valuation from the ethnography of reinsurance markets and the social studies of finance, such requirements appear either as an alarming attack against the actuarial component of traditional valuation practice, or else as a preserver of it, through a process of enfolding at the heart of the financialisation project. This article holds that the case of S2 challenges both these analytics of valuation. S2’s financialisation project, precisely by attempting to construct itself, deconstructs itself into an actuarial project, in a recurring, aporetic process. In this respect, fair (or otherwise) valuation remains always undecidable, inconclusive, and thus responsible.
The market, the regulator, and the government: Making a blockchain ecosystem in the Netherlands
Authors: Faria Inês 
Published: May 2021

AbstractThis article presents a socio-anthropological analysis of the formation of a business ecosystem around blockchain technology in the Netherlands, within the broader context of the European Union and the digital single market. I argue that while reproducing widespread global models of business group and network formation, the relations created by these networks also reveal particularities of local business and governance cultures. Such particularities emerge from the pragmatics of collaboration and competitive market relationships, as well as legal heterogeneity and plans for legal harmonisation in digital innovation and governance in Europe. They also emerge from the challenges and transformations that current experimentation cultures for digital innovation bring to the interactions between market players, regulators, and government. These challenges and transformations materialise in increasingly informal connections and strategies for experimental legitimisation, which occur in parallel to more formal and traditional forms of regulatory and governmental interaction. The article is based on ethnographic fieldwork in the Netherlands and in online terrains, including observation periods and 32 interviews with entrepreneurial project teams, as well as with individuals involved in financial incumbents’ innovation labs.
