COVID-19 pandemic has changed the normal course of activities around the World. The measures implemented to slow down the spread of the disease and its impact on the health system have also suggested a change in population dynamics. In the educational aspect, the paradigm of the traditional education had to change completely to a remote environment, representing a challenge for students, teachers, and education institutions. In this work we report the students’ response to the actions taken by the faculty of the Chemistry Sciences School of Universidad La Salle México to face online courses ensuring student accompaniment. After the term, a qualitative and quantitative study was performed to the school population using an electronic survey to address the response of students to the applied strategy. Data was analyzed using SPSS® software. 266 responses were obtained, which represents a response rate of 44%. 75.6% of the alumni reported having a good or excellent disposition regarding virtual sessions. Likewise, 48.9% reported adapting appropriately to the remote working modality. Also, 83.5% of students recognize the labor of the teachers by acknowledging that their effort and dedication was excellent or good. Students showed development of soft skills such as self-time and learning management; written, oral and technological communication. These results suggest the advantages perceived by students during the transition to virtual modality, mostly oriented to self-management of their learning and that could conform the basis for the development of new strategies that can be useful not only for a contingency situation, but also in the structuration and innovation of science programs.

Perencanaan pembangunan sarana dan prasarana sumber daya air yang akan dilaksanakan haruslah dapat meningkatkan kesejahteraan masyarakat karena pendapatan dan pertumbuhan dapat diperoleh berupa hasil pertanian, pertambangan, usaha kecil menengah, perdagangan, dan perindustrian. Pengelolaan sumber daya air dalam suatu Daerah Aliran Sungai haruslah dilakukan secara holistik yaitu memandang masalah secara utuh, terpadu dan, lintas sektoral, lintas daerah sesuai dengan konsep DAS sebagai kesatuan ekosistem. Perlunya menjaga hutan agar tetap lestari sehingga pembangunan DAS dalam economic development, community development dan environmental service bisa berimbang. Lahanlahan kritis dan gundul kembali hijau, air sungai yang bersih tersedia sepanjang tahun, musim hujan tidak lagi terjadi banjir dan longsor, musim kemarau tidak lagi kekeringan. Lahan dipinggir sungai Krueng Aceh di Kota Banda Aceh sangat subur dikarenakan humus tanah yang dibawa air sangat baik untuk tanaman jangka pendek. Kegiatan ini menjadikan aliran sungai terawat baik dan dapat melestarikan Daerah Aliran Sungai dari degradasi akibat pengikisan air, dan disamping itu juga dapat meningkatkan ekonomi masyarakatnya.
Controversies involving the use of SSRIs during pregnancy and the increased risk of having a child with autism spectrum disorders – a case report and literature review

Published: April 2021

Summary

Introduction: There is an ongoing debate as to whether the use of selective serotonin reuptake inhibitors (SSRIs) by pregnant women increases the risk of developing autism spectrum disorders (ASD) in the offspring.

Aim: The aim of the study was to
1) present, based on a case report, the potential factors that may affect the development of ASD in a child,
2) review the literature on the risk of ASD in the case of using SSRIs by a pregnant woman.

Case report: The case report concerns a child of a 33-year-old patient, previously treated for an episode of depression at the age of 23. At the beginning of the 15th week of planned pregnancy, when she was 28 years old, sleep disturbances were observed. Over the next few weeks, she gradually developed a full-blown depressive syndrome which required the use of sertraline. The child was born through a natural delivery, a healthy boy, who was diagnosed with ASD at the age of 2.5 years, which was the trigger for the development of the third episode of depression in the patient.

Conclusions: The results of the research indicate that SSRIs can penetrate the placental barrier, influencing the processes of serotoninergic transmission in the fetus, disrupting neurodevelopmental processes. On the other hand, a higher risk of ASD development in children of depressed mothers who do not use pharmacotherapy was confirmed, compared to the general population and in the case of the occurrence of depressive episodes in mother in the past and in relation to the male fetuses. The greater risk of ASD in children of mothers who take SSRIs may not only be associated with the medication itself but also with the presence of depression and the probable common genetic basis for both disorders. In each case, other risk factors for the development of ASD should also be taken into consideration, e.g. vitamin D3 deficiencies, unsaturated fatty acids, oxytocin levels, the presence of intestinal dysbiosis.

Abstract
This study investigates the impact of trade and transport services on the environment in Africa. Secondary data for 21 countries spanning 2000 and 2014 were used and analysed using POLS, FE, RE and PMG. These techniques revealed diverse results. The Hausman test was used to decide between FE and RE in the study. The Hausman test accepts the FE result due to it 5% significant result. The POLS reveal that trade and economic growth reduces degradation in Africa, while transport services in the export and import sector and energy consumption increases degradation. Notably from the FE result, trade, energy consumption and economic growth showed a positive impact on environmental degradation in Africa, while transport services in the import and export sector reduces environmental degradation. For the PMG result, findings show that in the long-run, trade, transport services (export and import), energy consumption, and economic growth increase degradation in Africa. This implies as these activities increases in the long run, there are no measure to ensure environmental quality. In the short-run, trade and transport services in the import sector reduce degradation as many of the importation is dominated by improved technology products, while transport services in the export sector, energy consumption and economic growth positively impact on environmental degradation in Africa. The study concludes a mixed effect of trade and transport services on the environment in Africa. A major recommendation is that more energy efficient technologies should be used in Africa to meet the sustainable environment goal and this can be done by reviewing trade policy to encourage inflow of improved technology into the economies.
Antithrombotic Drugs in Cirrhosis
Authors: State Nicoleta , Stoica Victor 
Published: April 2021

Abstract
In patients with liver cirrhosis treated for portal vein thrombosis, there was no increase in the risk of bleeding, but there was a decrease in the incidence of liver decompensation and an increase in the survival of treated patients when compared to the untreated ones(1).
Current guidelines(2) do not provide specific recommendations for the prophylaxis or treatment of thromboembolic diseases in patients with liver cirrhosis(3).
In order to determine the influence of anti-thrombotic treatment on the prognosis of liver cirrhosis, 85 patients with liver cirrhosis were followed clinically, by laboratory and ultrasound parameters, for 6 months. Microsoft Excel and IBM SPSS Statistics 20 were used to analyse the data of patients, divided into two groups according to the presence or absence of anti-thrombotic treatment initiated for cardiovascular pathology.
The obtained results showed that the mortality rate between the two groups was similar: 11.54% untreated, 12.12% treated, the decompensation rate of untreated patients was higher than that of the treated ones (36.54% vs. 24.24%) with antithrombotic drugs and that no patient among those treated with antithrombotic drugs showed upper digestive haemorrhage (p =0.038).
The conclusions drawn from this study were that patients with liver cirrhosis in antithrombotic treatment have a better prognosis than untreated ones, in the absence of major bleeding complications, but for a change in guidelines and current practice, studies are needed on a larger number of patients in order to validate these observations.

Published: April 2021

Abstract
Patients with chest pain presenting to the emergency room are currently investigated using either invasive coronary angiography (ICA) or noninvasive coronary computed tomography angiography (CCTA). ICA remains an expensive diagnostic tool and exposes patients to a high risk of periprocedural complication. Besides the currently available expansive economic evidence, there is still an important lingering issue: to establish, from the healthcare provider’s point of view, which is the most cost-effective investigation tool for the detection of significant coronary artery disease. The aim of this article is to present the latest developments in the field of imaging tools for the detection of coronary atherosclerosis in patients with chest pain, from the perspective of a cost-effectiveness analysis.

Published: April 2021

Abstract
An approximate method for analysis and synthesis of moving rigid bodies (prisms) in the airflow without using numerical methods of space-time programming techniques is described by applying a fluid (air)–rigid solid body interaction concept for engineering applications through a straightforward mathematical model. The interaction of rigid body (prism) and air is encountered in different cases: moving body (prism) in the air; stationary bodies (prism) in the airflow; moving body (prism) in the airflow. The complicated task of rigid body (prism) and air interaction is simplified by using superposition principles, i.e., by taking into account the upstream and downstream rigid body (prism) and air interaction phenomenon, which has been found to be different under varying speeds. Numerical results obtained for various forms of prisms are shown for constant air–speed, where the steady state Reynolds-averaged Navier–Stokes (RANS) equation is solved by using k-ε realizable turbulence model. A detailed explanation to support the proposed approximate method is given by using numerical results obtained in ANSYS computations. All equations are formed based on laws of classical mechanics; the interaction of viscous forces is neglected in forming the mathematical model. Numerical results for different model prisms are compared and the theoretical results discussed in detail. The mathematical model in the present paper is applicable only to bodies that undergo a rectilinear translation motion. In the final part of the present paper, the proposed method is used in the synthesis and optimization task of energy extraction by considering the motion of a variable parameter prism in the airflow.

Published: April 2021

Abstract
The electrochemical impedance spectroscopy (EIS) and corrosion behaviour of physical vapour deposited (PVD) TiAlN and TiCN coatings of 50 µm mesh shaped AISI 316 stainless steel were estimated under simulated marine conditions (3.5 wt. % NaCl solution). The coatings were prepared by creating adhesive Cr-CrN interlayer with the thickness of about 0.3 µm. The obtained thicknesses of produced coatings were measured to be in a range between 2 and 3.5 µm. The presence of protective coatings leads to corrosion potential (Ecorr
) shifting to more positive values as compared to the bare stainless steel. This effect indicates higher protection efficiency of coated steel under marine conditions. The protective behaviour of produced coating leads to the decreased corrosion current density (jcorr
) by indicating up to 40-fold higher polarization resistance as compared to resistance of the naturally formed oxide layer over the stainless steel. The Nyquist and Bode plots were obtained with the help of EIS measurements by applying alternating potential amplitude of 10 mV on observed Ecorr
. The obtained plots were fitted by appropriate equivalent circuits to calculate pore resistance, charge transfer resistance and capacitance. The present study reveals that pore resistance was the highest in the case of TiCN coating (Rpore
=3.22 kΩ·cm2). The increase in duration of the immersion up to 24 h leads to change in the capacitive behaviour of the coatings caused by the penetration of the aqueous solution into pore system of TiCN coating with low wettability and surface passivation of reactive TiAlN coating. The presence of defects was confirmed by examining the obtained samples with the help of the scanning electron microscope.

Abstract
Aluminosilicate mesoporous materials were synthesized using F108 template (polyethylene glycol-polypropylene glycolpolyethylene glycol) at a concentration of 0.034 g/ml and the molar ratio of Al2O3 to SiO2 was 0.09. The products were then characterized using nitrogen adsorption/desorption tests, scanning electron microscopy (SEM), and X-ray diffraction (XRD). The effects of various crystallization temperatures as well as sodium hydroxide concentrations on the average diameter, pore volume, surface area, and morphology of the synthetic material were analyzed. Results showed that a sodium hydroxide concentration of 11 mol/L and a crystallization temperature of 130 °C produced a synthetic material with regular pore size and homogeneous arrangement including a specific surface area of 137.62 m2/g, an average pore volume of 0.27 cm3/g, along with an average pore size of 15.33 nm.

Sounding the Forgotten Voices of Contemporary Chant
Authors: Helferty Emily 
Published: April 2021

Although created more than 1000 years ago, medieval Christian chant and polyphony is still used in concert halls and churches. Questions remain, however, about whether 21st century performances should attempt to replicate earlier practices or reflect the creativity of the present day. This project focuses on the tension between evolutionist and preservationist mindsets that pervade Early Music, exploring the contrasting views that chant is an evolving and living tradition or that chant should be learned and performed as close to its original use as possible. Through a combination of bibliographic and ethnographic research I studied the views of Early Music scholars and conductors/directors on the current use of chant in and outside of the context of worship. From this research, I uncovered a fascinating paradox regarding authenticity in performance practice. It appears that scholars are overwhelmingly motivated by a desire for authenticity in their arguments for preservation or evolution, whereas the two church pastors and four contemporary directors and performers of chant in Eastern Ontario that were interviewed in this project expressed far more varied opinions. These were rarely attached to a desire for authenticity, despite being among few who use chant in its most “authentic” context of worship. This project draws attention to the absence of scholarship on chant performers and their motivations, giving a voice to the singers of chant in the contemporary world.

Published: April 2021

Objectives:
The aim of this study was to assess the role of impacted third molar angulation on the severity of anterior crowding.

Materials and Methods:
Panoramic radiographs and three-dimensional (3D) digital models of 45 patients satisfying the following inclusion criteria were selected for this study. To calculate the irregularity index of Little, the sum of the contact point displacements from the anatomical contact point to the contact point among the lower canine teeth was measured on 3D digital models. Little’s irregularity index was used to classify patients as having mild, moderate, or severe crowding. For intragroup variance, comparisons T test was used. The Spearman single rank correlation coefficients were used to analyze any correlation among degree of crowding and (a) third molar inclination to base of mandible, (b) third molar inclination to occlusal plane, and (c) third molar inclination to second molar inclination respectively.

Results:
There were no statistical differences found in all tested parameters (i.e., third molar inclination to mandibular plane, inclination of the third molars to occlusal plane, and inclination of the third molars to second molars) among three groups (P > 0.005).

Conclusion:
It can be deduced that no relationship obtains among the third molar inclination to base of mandible, third molar inclination to occlusal plane, third molar inclination to second molar inclination, and the level of anterior crowding.
