A Convenient Approximation of the Projectile Motion with Quadratic Air Resistance
Authors: Landon Marc 
Published: December 2021

Abstract
A convenient approximated analytic solution is proposed for the problem of the motion of a body under a resistive force, acting in the magnitude of the squared velocity of the body. This solution is an explicit function of time, that keeps a good behavior both near the initial state and far from the initial state.

To obtain a general analytic solution, we firstly used a reduction principle to be able to manipulate scalar objects, and we analyzed limit behaviors, both near the initial state and far from the initial state. Secondly, we proposed an approximated analytic solution with heuristics based on the built knowledge.

Finally, a robust and stable integration scheme is proposed, based on the obtained analytic solution. We compared the scheme with other standard integration schemes.
Costs and optimisation options for monitoring of indirect dischargers
Authors: Franz T. 
Published: December 2021

Abstract
Monitoring of indirect and industrial dischargers, respectively, makes an important contribution to the safe and environmentally sound operation of wastewater systems. As a result of local framework conditions, there is a wide range of monitoring practices across Germany. In a benchmarking project, ten sewerage operators and monitoring bodies representing large German cities have collected data on their work and discussed their practices. The results show that the extent of monitoring is between 244 and 1,457 monitoring points per sewer network (given as 15th and 85th percentile). The median value of the specific expense is 689 EUR per monitoring point and year. In relation to the total wastewater fee volume, the median expense is 0.71%. The sub-process ‘sampling’ was examined more closely. By means of detailed process mapping and regression analyses, it can be shown that on-site activities and tours have the largest share of working time (total of 72%) and thus the greatest leverage in optimisation measures. Various examples are given.

Authors: Raheja Hemant , Goel Arun , Pal Mahesh 
Published: December 2021

Abstract
The present paper deals with performance evaluation of application of three machine learning algorithms such as Deep neural network (DNN), Gradient boosting machine (GBM) and Extreme gradient boosting (XGBoost) to evaluate the ground water indices over a study area of Haryana state (India). To investigate the applicability of these models, two water quality indices, namely Entropy Water Quality Index (EWQI) and Water Quality Index (WQI) are employed in the present study. Analysis of results demonstrated that DNN has exhibited comparatively lower error values and it performed better in the prediction of both indices, i.e. EWQI and WQI. The values of Correlation Coefficient (CC = 0.989), Root Mean Square Error (RMSE = 0.037), Nash–Sutcliffe efficiency (NSE = 0.995), Index of agreement (d = 0.999) for EWQI and CC = 0.975, RMSE = 0.055, NSE = 0.991, d = 0.998 for WQI have been obtained. From variable importance of input parameters, the Electrical conductivity (EC) was observed to be most significant and ‘pH’ was least significant parameter in predictions of EWQI and WQI using these three models. It is envisaged that the results of study can be used to righteously predict EWQI and WQI of groundwater to decide its potability.

Psychedelics and Hallucinogens in Psychiatry: Finding New Pharmacological
Targets
Authors: Sousa Teresa Reynolds , Rema João , Machado Sergio , Novais Filipa 
Published: December 2021

Background:
The therapeutic options for neurobehavioral disorders are still limited, and
in many cases, they lack a satisfactory balance between efficacy and side effects.

Objective:
This work aims to review current evidence regarding the potential contribution of
psychedelics and hallucinogens to the discovery of new drugs for treating different psychiatric disorders.

Discussion:
Ayahuasca/N,N-dimethyltryptamine (DMT), lysergic acid diethylamide (LSD), and
psilocybin have evidence supporting their use in depression, and psilocybin and ayahuasca have also
shown good results in treatment-resistant depression. In randomized controlled trials (RCTs)
conducted with anxious patients, there were symptomatic improvements with psilocybin and LSD.
Psilocybin diminished Yale-Brown Obsessive Compulsive Scale (Y-BOCS) scores in a small obsessive-
compulsive disorder (OCD) sample. The evidence is less robust regarding substance use disorders,
but it suggests a possible role for LSD and psilocybin in alcohol use disorders and for
psilocybin in tobacco addiction. In a clinical setting, these substances seem to be safe and well-tolerated.
Their mechanisms of action are not fully elucidated, but there seems to be a preponderant
role of 5-hydroxytryptamine (5HT) 2A agonism, as well as connectivity changes within the default
mode network (DMN) and amygdala and some other molecular modifications.

Conclusion:
The studies underlying the conclusions have small samples and are heterogeneous in
their methods. However, the results suggest that the use of psychedelics and hallucinogens could
be considered in some disorders. More studies are needed to reinforce their evidence as potential
new drugs.
Evaluation of the Antidepressant-like Effect of Chronic Administration of
Nigella Fixed Oil Versus Fluoxetine in Rats
Authors: Kadil Youness , Tabyaoui Imane , Badre Latifa , Jouti Nadia Tahiri , Filali Houda 
Published: December 2021

Background:
Depression is a group of syndromes characterized by notable and persistent
mood disorders, and is one of the most prevalent psychiatric disorders, while the existing treatments
have an altered risk-benefit balance. The therapeutic properties of Nigella have been confirmed,
suggesting the reliance on phytotherapy. The objective of the present paper is to investigate
the antidepressive-like effect of Nigella sativa on rats exposed to the Unpredictable Chronic Mild
Stress procedure.

Methods:
Wistar rats were used to investigate the antidepressive-like effect. The stress procedure
used in this study combined many stressful conditions. After 6 weeks of treatment, behavioral test
(forced swim test) was conducted, and histological changes of the hippocampus were examined.

Results:
Treatment by nigella and fluoxetine significantly reduced the struggling time.

Conclusion:
Histopathological analysis showed that control treatments result in more loosely arranged
cells, significant apoptotic neurons characterized by an irregular appearance, and pyknotic
hyperchromatic. A reduction of the thickness of the pyramid layer was also observed in the groups
treated with nigella and fluoxetine, suggesting that nigella could be used as a treatment or an adjuvant
preventing depressive-like disorders.
Ethical Issues in Social Media Recruitment for Clinical Studies: Ethical Analysis and Framework
Authors: Zimmermann Bettina M , Willem Theresa , Bredthauer Carl Justus , Buyx Alena 
Published: December 2021

Background
Social media recruitment for clinical studies holds the promise of being a cost-effective way of attracting traditionally marginalized populations and promoting patient engagement with researchers and a particular study. However, using social media for recruiting clinical study participants also poses a range of ethical issues.

Objective
This study aims to provide a comprehensive overview of the ethical benefits and risks to be considered for social media recruitment in clinical studies and develop practical recommendations on how to implement these considerations.

Methods
On the basis of established principles of clinical ethics and research ethics, we reviewed the conceptual and empirical literature for ethical benefits and challenges related to social media recruitment. From these, we derived a conceptual framework to evaluate the eligibility of social media use for recruitment for a specific clinical study.

Results
We identified three eligibility criteria for social media recruitment for clinical studies: information and consent, risks for target groups, and recruitment effectiveness. These criteria can be used to evaluate the implementation of a social media recruitment strategy at its planning stage. We have discussed the practical implications of these criteria for researchers.

Conclusions
The ethical challenges related to social media recruitment are context sensitive. Therefore, social media recruitment should be planned rigorously, taking into account the target group, the appropriateness of social media as a recruitment channel, and the resources available to execute the strategy.

Published: December 2021

Background
Developments in digital health have the potential to transform the delivery of health and social care to help citizens manage their health. Currently, there is a lack of consensus about digital health research priorities in palliative care and a lack of theories about how these technologies might improve care outcomes. Therefore, it is important for health care leaders to identify innovations to ensure that an increasingly frail population has appropriate access to palliative care services. Consequently, it is important to articulate research priorities as the first step in determining how finite resources should be allocated to a field saturated with rapidly developing innovation.

Objective
The aim of this study is to identify research priority areas for digital health in palliative care.

Methods
We selected digital health trends, most relevant to palliative care, from a list of emerging trends reported by a leading institute of quantitative futurists. We conducted 2 rounds of the Delphi questionnaire, followed by a consensus meeting and public engagement workshop to establish a final consensus on research priorities for digital technology in palliative care. We used the views of public representatives to gain their perspectives on the agreed priorities.

Results
A total of 103 experts (representing 11 countries) participated in the first Delphi round. Of the 103 experts, 55 (53.3%) participated in the second round. The final consensus meetings were attended by 10.7% (11/103) of the experts. We identified 16 priority areas, which involved many applications of technologies, including care for patients and caregivers, self-management and reporting of diseases, education and training, communication, care coordination, and research methodology. We summarized the priority areas into eight topics: big data, mobile devices, telehealth and telemedicine, virtual reality, artificial intelligence, smart home, biotechnology, and digital legacy.

Conclusions
The priorities identified in this study represent a wide range of important emerging areas in the fields of digital health, personalized medicine, and data science. Human-centered design and robust governance systems should be considered in future research. It is important that the risks of using these technologies in palliative care are properly addressed to ensure that these tools are used meaningfully, wisely, and safely and do not cause unintentional harm.

Este artículo presenta el análisis del texto del villancico Guineo a 5, Eso rigor e repente escrito por Gaspar Fernandes, maestro de capilla de Puebla, a comienzos del siglo XVII. En dicha composición se pueden percibir ciertos elementos que remiten a la realidad cotidiana y a la visión que la sociedad tenía de los africanos y afrodescendientes en la ciudad de Puebla y la Nueva España. Destaca en este análisis la identificación de elementos de pensamiento espiritual y religioso africano o afrodescendiente (principalmente bantú) en el villancico, probablemente como una referencia a las prácticas de religiosidad católica afrodescendiente realizadas por esta población. Puebla fue un espacio urbano donde hubo cofradías de negros y músicos afrodescendientes dentro de la capilla musical catedralicia al momento en que se escribió y estrenó este guineo.

Published: December 2021

Abstract
The objective of the paper was to describe the impact of freeze-drying conditions on hardness of lyophilizates obtained based on soft fruit pomace. Raspberry, cherry, and grape pomace from the pressing process carried out with a low-speed rotary press constituted a research material. Immediately after the pressing process, pomaces were placed in forms, frozen, and after freezing they were freeze-dried in the pressure of 20, 42, 63, 85 and 110 Pa. The obtained lyophilizates were subjected to the measurement of hardness with the use of texture meter equipped with a penetrometer in the form of a cone with a vertical angle of 30°. The increase of pressure during freeze-drying of samples was accompanied by the increase of hardness of the obtained lyophilizates, which may affect the energy consumption of the grinding process and the nature of rehydration of the final product. Moreover, the water content of raw material, pomaces, and lyophilizates was determined. The obtained results of measurements were subjected to a statistical analysis which showed that the pressure of freeze-drying significantly diversifies the hardness of the obtained lyophilizates.
