Authors: Hu Andy , Chen Dale , BCIT School of Health Sciences, Environmental Health
Published: August 2022

Phthalates are chemical agents used to improve the plasticity of plastic products. Their ubiquitous use in various commercial products results in extensive exposure to humans. Toxicological studies have linked phthalate exposure to developmental and reproductive toxicity, presenting potential health risks. This study investigated the general population on their knowledge and hazard perception of phthalate exposure. The assessment determined if changes in policies or guidelines are needed to minimize potential health impacts from improper plastics handling.
Practice and attitude of pet owners feeding raw based pet diets compared to non-raw based diets
Authors: Bjornson Keyana , Chen Dale , Environmental Health BCIT School of Health Sciences
Published: August 2022

New trends in raw based diets are putting people at a higher risk for becoming ill from pathogens. An outbreak investigation of pig ears containing Salmonella found over 50% of the tested pig ears were positive for the bacteria and 38% of pet treats contained Salmonella. At the time of the outbreak, pet owners became ill with Salmonella which was believed to be from handling the pig ears or from their ill pets that were carrying the bacteria. An outbreak in Italy involving kibble demonstrates there is a risk when feeding raw and non-raw diets.

Authors: Yang Ming Mei , Heacock Helen , Environmental Health BCIT School of Health Sciences
Published: August 2022

The Covid-19 pandemic has created a high demand for hand sanitizer to prevent the spread of pathogens. This resulted in a hand sanitizer shortage on the market and promoted more manufactures to produce and sell hand sanitizers. Meanwhile, Health Canada has recalled many hand sanitizers due to potential health risks for various reasons such as products that contain unauthorized ingredients. However, the general public in Canada might not notice hand sanitizer recalls and/or underestimate the risk of using recalled hand sanitizers. This research study was conducted to determine the general public awareness regarding hand sanitizer recalls.

Authors: Zhang John , Heacock Helen , British Columbia Institute of Technology School of Sciences
Published: August 2022

Mask-wearing in public spaces has become ubiquitous for most people in developed countries due to the ongoing pandemic. One key aspect of the protectiveness of masks is how many times it is used before disposing of (in the case of surgical or disposable masks) or washed (a cloth or reusable mask). Assessing mask reuse levels in key demographics can help us identifywhich groups are reusing masks more, and targeted educational campaigns can be accomplished which would hopefully lead to reduced mask reuse.

Authors: Lee Seulbi , BCIT School of Health Sciences, Environmental Health  , Chen Dale
Published: August 2022

Extreme Heat Events (EHEs) are increasing in frequency, intensity, and duration in Canada that are resulting in high numbers of preventable heat-related illnesses and deaths. Apart from heat related injuries, extreme heat can catalyze reactions to worsen the outdoor air quality, increase wildfire occurrences, and worsen pre-existing heart conditions or chronic illnesses. Assessing the general public’s knowledge of protective measures against EHEs is needed to prevent further heat-related injuries. In addition, the general public’s knowledge of climate change can be determined to assess if they are aware of the contribution of extreme heat.
Sensitivity of infrared sensor faucet on different skin colours and how it can potentially effect equity in public health
Authors: Qi Ren Xiao , BCIT School of Health Sciences, Environmental Health  , Heacock Helen
Published: August 2022

Hand hygiene is essential to human health and day-to-day activities. Maintaining proper hand hygiene can help reduce pathogen growth and transmission of diseases. The automated sensor used for bathroom faucets and soap dispensers can be dated back to the 1950s. These types of fixtures are usually equipped with sensors using a near-infrared beam to detect hands. Its introduction has improved hand hygiene and facilitated good handwashing behaviour. At the same time, disadvantages that come along with advanced technologies should not be neglected, and these disadvantages may lead to inequity in the society.

Authors: Cotrim Irlan
Published: August 2022

Analisamos no presente artigo como a imagem pública de Domiciano, último Imperador da dinastia flaviana (69-96), foi construída a partir dos Ludi Saeculares ocorridos em 88, tomando como documentação as moedas cunhadas em Roma sobre o evento. Para tanto, recorremos aos conceitos de representações e de práticas de Roger Chartier (2002) e de propaganda aplicada aos Estudos Clássicos, noção que foi amplamente discutida por Paulo Martins (2011) e por Ana Teresa Marques Gonçalves (2013). O método adotado foi o da Análise de Conteúdo, de Laurence Bardin (2011). Concluímos que o Imperador, para além das reverências divinas, foi representado como um governante com uma política baseada na liberalitas e na proximidade com período augustano.

Published: August 2022

In the context of the rapid changes that have occurred in recent years, characterized by veritable 'black swans' such as the COVID-19 pandemic and extreme weather events that are occurring with increasing frequency, the issue of climate change has come into the focus of banking regulators and supervisors. Therefore banking institutions, if they are subject to the Single Supervisory Mechanism, have been called upon to develop (and, subsequently, to integrate into their business practices) methodologies for the identification, quantification and management of such risks, mainly under the profiles of: - Transition Risk, associated with policies undertaken by governments to foster climate change mitigation and adaptation; - Physical Risk, associated with the occurrence of extreme climatic events and its impact on the bank's assets. This paper analyzes one of the most significant hazards within the Physical Risk domain, which is Flood Risk. The measurement is focused on the prospective evolution of the flood events on a portfolio of mortgages secured by residential properties. The impact of this risk driver is subsequently reflected through the movement of appropriate transmission mechanisms on the LGD and PD parameters relating to the exposures in the scope. Finally, the effect on loan adjustments is provided, by recalculating the expected losses that result from the stressed projections. The flood risk projection is executed on a long-term timeframe, developing over 3 climate scenarios up to 2050. The choice of this hazard is due to its relevance in terms of frequency of events and harmfulness, a relevance that is confirmed by its inclusion in both the top-down climate stress testing exercises carried out by the ECB and in the bottom-up climate stress testing exercise promoted by the ECB itself in 2022 and carried out by the SSM Banks. A comprehensive simulation framework, structured as follows, is then presented: - a macro-climate scenario simulation engine; - the downscaling of these scenarios to obtain localized climate effects on individual properties; - the transmission of these effects into a depreciation formula for the individual property; - the LGD stress associated with the devaluation of the collateral property, and the PD stress that goes along with it, obtained by correlation.
Virtual Reality Glasses versus Midazolam in Alleviation of Child’s Anxiety during
Dental Rehabilitation: Randomized Controlled Clinical Trial
Authors: Rizk Raghda , M. Ali Amel , Abdellatif Hoda , Dowidar Karin ML.
Published: August 2022

Objective: To evaluate virtual reality glasses versus premedication with oral midazolam, and their effect on separation anxiety and postoperative behavioural changes in children experiencing dental rehabilitation under general anaesthesia. Introduction: Several children suffer anxiety when experiencing dental rehabilitation under general anaesthesia, which may be caused by separation from parents, and negative anticipation of surgical procedures. Midazolam (MDZ) is a generation of Benzodiazepines that have been widely used as a premedication. Whereas distraction is a common technique used to reduce pain and anxiety during short invasive procedures. Methodology: This was a randomized clinical trial; children aged 4-6 years who were healthy, uncooperative, and planned to be treated using general anaesthesia were randomly distributed between two groups (Group I), using the Virtual glasses and (Group II), given oral midazolam. The baseline heart rate (HR) was recorded twice. Ease of separation was assessed for all the participants using the Parental Separation Anxiety Scale (PSAS). The Postoperative behavioural changes were scored using (PHBQ) Questionnaire after 24 hours and 14 days after the operation. Results: Regression analysis showed that the type of intervention was non-significantly associated with the acceptability of separation. Males showed significantly less acceptable separation than females. There was a statistically significant increase in the heart rate readings in both groups when compared before and after separation. The parent-reported child morbidity following the surgery showed no significant difference except when regarding the children “who were upset at mentioning doctors, dentists or hospitals” where (P=0.000). Conclusion: VR and premedication with oral midazolam were both effective strategies for controlling preoperative anxiety in children during parental separation, with lots of advantages when using the VR distraction approach.
Chemical Analysis of DG Cement’s Municipal Waste Used for Refuse Derived Fuel
Authors: Bilal S
Published: August 2022

Purpose: Rampant population growth particularly in South Asian region has turned solid waste management a challenging task. Huge resources are squandered for collection and disposal without considering the recyclable and energy potential. However, in Pakistan, some companies are utilizing waste as refuse derived fuel (RDF) – a process to separate combustibles from municipal waste in order to generate energy.

Methodology: For RDF analysis, DG cement RDF plant near Lakhodair landfill site Lahore was selected in order to collect RDF raw waste, which are then converted in to RDF pellets for further analysis. The chemical analysis consisted of proximate analysis (moisture content, volatile combustion matter, fixed carbon & ash content) and net calorific value (NCV) along with heavy metal analysis.

Findings: Upon analysis, percentage of volatile combustible matter (VCM) tetra pack and jute was about 84% followed by other waste and thermo-pole 78%. Fixed carbon (FC) of wrappers and paper waste was about 24 and 16% whereas Ash content (AC) was recorded highest in textile, shoppers, thermos-pole and foam with 14% while rest 10%. The moisture content (MC) of other waste type followed by shopping bags and jute was found highest among other component such as 3.5%, 24% and 20.9% respectively. Moreover, the highest calorific value was obtained in plastic wrappers (61.26 MJ/kg) whereas lowest was observed in jute (6.4 MJ/kg). For heavy metal analysis such as Chromium (Cr), Lead (Pb), Cadmium (Cd) and Copper (Cu), Atomic Absorption Spectrophotometry (AAS) was used; highest concentration of copper was observed in the foam waste (45.5 mg/kg) and the lowest value was observed in thermos-pole (8.5 mg/kg). All the results were in EURITS standards range.

Recommendation: Therefore, in the light of above analysis, it was confirmed that collected waste is highly feasible for RDF in DG cements.
CONTRIBUTION OF JGI REDD+PROJECT IN ADDRESSING DEFORESTATION, CLIMATE VARIABILITY AND PEOPLE’S LIVELIHOODS IN WESTERN TANZANIA: A CASE OF ILAGALA, KARAGO AND KIRANDO VILLAGES
Authors: Makunga John E. , Misana Salome B.
Published: August 2022

Purpose: The study examined the contribution of REDD+ in addressing deforestation, climate variability and people’s livelihoods in three villages of Ilagala, Karago and Kirando, within the REDD+ Masito-Ugalla ecosystem in Uvinza District, Tanzania. Methodology: The methods used were household interviews, semi-structured interview, focus group discussions, field observations, analysis of meteorological data, as well as remote sensing and geographical information systems (GIS). A total of 101 households were randomly selected for the study. Results: The trend of the mean annual rainfall and rainfall deviations from the annual mean revealed the presence of climate variability. Majority of the respondents agreed that climate variability was happening in their area. Deforestation and forest degradation were also a problem in the area as evidenced by expansion of cultivation at the expense of other vegetation types and opening up of the closed woodlands. The findings further revealed that majority of respondents were aware about REDD+ objectives and that the project had provided conservation education to local communities and supported them to alleviate poverty through establishing entrepreneurship groups within the project area, each group dealing with a specific activity, including beekeeping and poultry. Majority of the respondents said they were able to support the education needs of their children as benefits accrued to them during REDD+ operation. The contribution of REDD+ project in minimizing deforestation, climate variability and improving people’s livelihoods was manifested through training of forest monitors and fire breakers and establishment of community projects. The REDD+ performance, however, was reported to be on average. Also due to its short operation period, REDD+ did not significantly contribute to people’s livelihoods.   Unique contribution to theory, practice and policy: This study has provided important lessons on the importance and opportunities offered by REDD+ in addressing forest conservation and providing livelihood benefits to the local communities. Although REDD+ policies and projects are geared towards addressing climate change mitigation, if well designed, they can go a long way in alleviating poverty while at the same time conserving the forests. What is required is for nations to identify what the needs of the local communities and the desired benefits in the respective areas are and build into the REDD+ projects strategies that would adequately address those needs and provide the required benefits.

TRAJECTORY ANALYSIS OF OIL SPILL AT THE GULF OF GUINEA: CASE OF CAMEROON – KRIBI
Authors: Tohnain Fuchi
Published: August 2022

Objectives: The objective of this study was to determine the trajectory and duration of oil slick touching or reaching the shore of kribi-Cameroon in case of an oil spill in the coast of Guinea. With the trajectory analysis known, better contingency planning can be done to protect sensitive areas and the beach activating oil spill response.

Methodology: systematic review past articles on oil spill trajectory analysis from peer was done. This article shows how the surface currents, waves and wind direction affects oil slick movement. The used of GNOME for oil slick modelling as well as the ADIOS for better analysis including the oil dispersed with the estimated budget to clean up the spill provides a better tool for spill trajectory analysis.

Findings: There are two factors that affects the accuracy of oil slick trajectory analysis. The inability to obtain or measure wind and current speeds at the time of the spill and the rotation of the earth thus deflecting the spill either to the northern or southern hemisphere.

Recommendations: Crude oil does not degrade easily and can remain in the environment for decades. Oil production companies needs to put in place a rapid clean up response group with frequent drill exercise. This can help to contain the spilled oil in a timely manner to avoid spreading and further contamination of the sea and other sensitive area. Focus should be on their operating equipment, processes put in place for maintenance strategies and trained qualified personnel to operate their facility.

Authors: Awadh Asma , Mwakumanya Maarifa , Omar Mohamed
Published: August 2022

Purpose: This study aimed to assess Dugongs' status distribution of dugongs (Dugong dugon) in Kenya. A dugong is a herbivorous marine mammal of the tropical and subtropical Indo-West Pacific and the Indian Ocean. Dugongs are one of four existing species of the order Sirenia, which is considered most at risk of extinction. Globally, IUCN classified the Dugong as rare; Kenya has done the same under the Wildlife Conservation and Management Act 2013, thus making Dugongs a conservation priority. This paper discusses the traditional practices of dugongs and how this influenced their population and conservation.

Methodology: The study used a literature review, semi-structured questionnaires, guided interviews, and focus group discussions with respondents on obtaining data.  

Findings: More than 100 dugongs occurred in the Kenyan waters in the 1960s; their population has declined drastically since then.  Dugongs were a sought-after delicacy on the Kenyan coast. Dugong meat was consumed for its taste and nutritional use. In the northern study areas, its oil was separated and used for cosmetic and medicinal purposes.

Unique contribution to theory, practice and policy: This study confirms fishing practices and traditional consumption practices on dugongs were seen to have led to their detriment. The study recommends rich continuous education and awareness efforts to change the thinking and practices of the people towards conservation of dugongs and the environment in general.
THE IMPACT OF FOOD PACKAGING ON THE ENVIRONMENT AND WAYS OF MANAGING WASTES IN SELECTED GHANAIAN COMMUNITIES
Authors: Sebbeh Bartholomew
Published: August 2022

Purpose: The author sought to investigate into how food packaging wastes are handled in the Ghanaian communities, the impact of the wastes on the environment and ways by which the menace can be curbed.

Methodology: The study was descriptive in nature and observation was the main instrument adopted to gather information on the phenomenon of the threat of packaging waste on the Ghanaian environment. Such observations were conducted in parts of the three namely Accra, Kumasi and Sekondi - Takoradi major cities in Ghana. At least, five (5) suburbs in each of the metropolitan areas were studied.

Findings: The study revealed that plastic packaging waste generated in the country is currently the most post-consumer waste. Majority of the consumers in Ghana do not take cognizance of the environmental impacts of the products they consume and thus throw or dump packaging waste products indiscriminately.  They do not care about what will happen to it, to themselves as individuals and to the environment in general.

Unique contribution to theory and Practice and policy: The outcome of the study will enlighten the average Ghanaian on how to manage food packaging waste to help save the natural environment from unnecessary pollution, depletion and extinction of animals and marine habitat. This will enable policymakers in Ghana enact appropriate laws that will ensure the proper handling and management of the waste generated by manufacturers and consumers of food packaging.

Authors: Gathoni Benson , Munayi Simon P. , Chumba Janet
Published: August 2022

Purpose: Recreation sites and parks are exposed to degradation unless stringent conservation measures are undertaken. Recreational activities undertaken by visitors such as; camping, hiking and climbing, game driving, bird watching, bicycling, mountain biking, game viewing, and picnicking among others put huge pressure on the parks resources. The aim of the study is to determine the recreation activities that have the greatest negative environmental impact on environmental resource attributes in national parks of central Kenya.

Methodology: The descriptive survey research design was used. The study was conducted in the two designated national parks in Central Kenya region: Mt. Kenya and Aberdares. Stratified random sampling was used to ensure that the KWS and KFS officers in managerial, tour guide, maintenance, and security levels were represented.

Results: Two hundred and sixty three 263(79.9%) responded to the questionnaires by completely filling and returning them. Descriptive statistics that included frequencies and percentages were used to organize and summarize the data. Tables and bar charts were drawn to present the collected data. Independent Sample T-test was conducted to compare the mean of the visitors and staff on the perceived effect of recreation activities on environmental resource attributes. It is only on soil where the two groups were found to be significantly different ( (visitors) =2.14, staff) =1.50, t=6.06, df =233, p<0.001).

Unique contribution to theory, practice and policy: The study therefore concluded that parks environmental resource attributes are negatively affected by recreation activities in the national parks in the Central Kenya region. Through monitoring of conditions, managers will be able to more clearly identify when specific impacts have become so pronounced as to demand management attention.
MEMAHAMI MANAJEMEN PENDIDIKAN ISLAM DAN IMPLIKASINYA
Authors: Afrizal Ambo Fera
Published: August 2022

Pada dasarnya manajemen berasal dari to manage yang berarti mengatur, mengelola atau mengurusi. Ungkapan yang menarik mengenai manajemen adalah ungkapan yang dilontarkan Luther Gulick, yang dikutip Sulistiyorini, “manajemen sering diartikulasikan sebagai ilmu, kiat dan profesi.” Sebagai ilmu, manajemen dipandang sebagai suatu bidang pengetahuan yang secara sistematis berusaha memahami mengapa dan bagaimana orang bekerja sama untuk mencapai tujuan dan membuat system kerjasama yang lebih bermanfaat bagi kemanusiaan. Sementara itu, manajemen dipandang sebagai seni yaitu untuk melaksanakan pekerjaan melalui orang lain, dalam hal ini seorang manajer perlu mengetahui dan menguasai seni memimpin. Sedangkan sebagai profesi, dikarenakan manajemen dilandasi keahlian khusus untuk mencapai prestasi manajer yang diikat oleh kode etik dan dituntut untuk bekerja secara professional. Oleh karena itu seorang manajer harus membekali diri dengan kemampuan konseptual (POAC) serta kemampuan sosial dan kemampuan teknis yang dapat mendukung dalam pelaksanaan program yang dijalankan.

Change and Continuity in Early Nineteenth-Century Foodways in Québec City’s Lower Town
Authors: Mallet Gauthier Solène , Bain Allison , Trigg Heather
Published: August 2022

Plant and insect remains found in a privy structure were analyzed to gain insight into foodways of Québec City’s Lower Town inhabitants in the early nineteenth century. We use dietary practices as a window to examine how the population of the St. Roch neighbourhood responded to changes taking place in the decades that followed the instauration of the British regime and how these changes may have influenced different aspects of their food consumption practices. Through comparisons with assemblages from two French-regime sites as well as from three later nineteenth-century sites, we find that a certain continuity characterizes the plant consumption of Québec City’s French-Canadian population. We address some of the challenges of this research, as it is difficult to distinguish between consumption as a choice related to identity versus more practical considerations such as availability and access.
Pre- and Mid-Pandemic Analysis on Student’s Science Grades: a Key for Future Action Research
Authors: Richard A. Ducay,
Published: August 2022

The curse of the COVID-19 pandemic has greatly impacted the assessment of learning for the past two years. One of the disciplines that was greatly affected is Science. Science education is vital in human development. Most recently, numerous research articles have been published to assess assessment strategies, their effectivity and instrumentations across the globe. However, among these numerous research articles in the local and international scale, it can be observed that there is dearth in the assessment of student’s performance in Science. Thus, this study is conducted to assess the trend in student’s science grades before and during the pandemic in the Philippine Junior High School K to 12 curricula. This study employed a descriptive quantitative research design to attain the pre and mid pandemic analysis The respondents of this study were the Junior High School SY 2018-2019 and SY 2020-2021 completers. The acquired data shall be treated using T-Test of Independence. The results revealed that students’ grades in Science significantly increased during the pandemic era and become less varied which is evident in their lesser extent of its variability. This result runs counter to other researches on students output in time of pandemic and several areas need to be reassessed for its validity and reliability with students’ actual application of science skills which are lifelong vital tools. Thus, it is recommended that for future school-based action researches, educators should focus on themes like; Science skills and grades parallelism, modular and face to face modality comparisons, pandemic assessment lapses, and school problem management.

A MCDA-based Approach on Corporate’s Investment Decision Process: A case study of a Small-sized Firm’s decision on Foreign Direct Investment
Authors: Ribeiro Daniel Ricardo Pereira , Vieira Jose Geraldo Vidal , Nakano Davi
Published: August 2022

Small and medium-sized enterprises have frequently been facing great troubles in capital budgeting and investment decisions. Part of these troubles comes from the very nature of the modern financial decision problems. While well-known classic optimization methods can properly solve traditional financial decision problems with a single objective, they fail at solving real-world complex problems, which involves the interplay of multiple concurrent decision factors, against a backdrop of financial constraints. As a result, the corporate finance field has been demanding more sophisticated approaches, which integrate traditional quantitative methods with Multi-Criteria Decision Analysis techniques (MCDA), probabilistic models, simulations and optimization methods. This paper combines Corporate Finance theory with a MCDA approach based on the von Neumann-Morgenstern’s Utility Theory and presents a case study within a small-sized firm that needs to decide whether or not to expand into international operations, given a set of decision factors and financing constraints. The results deliver a structured decision framework to assist the firm’s managers, increasing impartiality in the investment decision process and help the decision makers (DM) reach a rightful, well-substantiated decision to their investment decision problem.
Students Quest for Nationalism
Authors: B. Manugas Stevie
Published: August 2022

Nationalism depicts values, cultures, practices, and sets of beliefs that are being shared by the students in society. However, in a vastly changing world where globalization takes place, students tend to adopt new things, concepts, and even the culture which leads to the changes in their mindset towards their perception of nationalism. This research argues that age and socio-economic status are determinant factors in one’s manifestation of nationalism in different directions. The said paper used a descriptive survey method that aimed to determine the level of nationalism of the students. These were the findings of this paper, first, most of the students belong to the 16-25 age bracket and the majority of them were females and were in the low-income bracket. Second, the level of nationalism of the students was high. Third, there was a negative significant correlation between the level of nationalism and respondents’ age. Younger students manifested a higher level of nationalism than the older ones. Moreover, there was a significant correlation between the level of nationalism and the respondents’ socioeconomic status. The higher the socio-economic status, the higher manifestation of the level of nationalism. Based on the findings of this paper, age and socio-economic status are determinant factors in one’s manifestation of nationalism in different directions.

Solitons are an important class of solutions to nonlinear differential equations which appear in different areas of physics and applied mathematics. In this study we provide a general overview of the Hirota method which is one of the most powerful tool in finding the multi-soliton solutions of nonlinear wave and evaluation equations. Bright and dark soliton solutions of nonlinear Schrödinger equation are discussed in detail

El consumo de flores comestibles ha incrementado la búsqueda de nuevas especies que permitan mejorar el impacto nutricional. Por ello, el objetivo de este estudio fue determinar el perfil fenólico y el valor nutricional de flores de algunos clones de Dahlia x hortorum (C1Var – variegado, C2Gui – guinda, C3Roj – rojo, C4Nar – naranja, C5Ama – amarillo, C6Fuc – fucsia y C7Ros – rosa). El experimento se realizó en el Departamento de Fitotecnia de la Universidad Autónoma Chapingo, México, bajo un diseño experimental completamente al azar con tres repeticiones. Se detectaron ácidos fenólicos (gálico, cafeico y clorogénico) y flavonoides (quercetina y hesperidina). Se encontraron contenidos similares de ácido gálico (entre 1.91 y 3.19 µg·g-1) en C7Ros, C1Var, C5Ama y C4Nar, donde C1Var también destacó por la presencia de quercetina (81.46 µg·g-1). La mayor incidencia de ácido cafeico y hesperidina se encontró en C2Gui y C6Fuc. En general, C1Var mostró alto porcentaje de fibra cruda, grasa cruda y proteína, aunque en este último fue similar a C7Ros y C5Ama (13.68 y 13.72 µg·g-1, respectivamente). Asimismo, C2Gui, C4Nar y C3Roj mostraron variación con respecto a los carbohidratos totales (64.09, 61.64 y 62.37 %, respectivamente). De acuerdo con los resultados, las flores liguladas de dalia poseen un contenido significativo de ácidos fenólicos, flavonoides, fibra y proteína, así como un nivel calórico variable, por lo que pueden ser consideradas como un alimento funcional y ser integradas en la ingesta diaria.

Introduction: Aortic angulation (AA), defined as the angle between the aortic annulus plane and the horizontal plane, may result in failed prosthesis positioning. The effect of AA on the procedural and short-term outcomes with the portico valves for transcatheter aortic valve implantation (TAVI) has not been fully investigated. The present study aimed to evaluate the impact of AA on device success and early outcomes of TAVI using a selfexpanding portico valve.

Patients and Methods: Preoperative computed tomography scans of 121 consecutive patients treated with the portico valve were analyzed. TAVI device success and outcomes were determined according to VARC-3 definitions. Patients were divided into two groups based on mean AA.

Results: The mean AA was 48.7 ± 8.9°. There were no differences in technical success (92.2 vs 89.5%, p= 0.604), device success (81.2% vs 77.2%, p= 0.582), and early safety endpoints (68.8% vs 61.4%, p= 0.397) between the AA≤ 48° and AA>48° groups. The frequency and severity of paravalvular aortic regurgitation (PAR) was statistically higher in patients with AA> 48° (p= 0.028). Moreover, an increased AA was also associated with valve malposition (12.3% vs. 1.6%, p= 0.018), prolonged procedure time (85 ± 26 vs. 75 ± 20 minutes, p= 0.028), and greater Δimplantation depth (2.2 ± 0.5 vs. 0.8 ± 0.1 mm; p<0.001).

Conclusion: Despite comparable device success and early outcomes rates, increased AA is associated with higher rates of PAR and valve malposition, with the self-expanding portico valve.
Dog Barbos and Unusual Cross in the Context of Soviet Culture, Folklore and “Game Fiction”
Authors:   State Institute for Art Studies, Salnikova E.V.
Published: August 2022

The article is devoted to the comedy by the Soviet film director Leonid Gaidai. The relevance of the topic is due to the approaching the 100th anniversary of the director’s birth (2023) and his high popularity throughout the post-Soviet years. At the Soviet time, however, criticism and film studies often denied that Gaidai’s films had semantic depth. The novelty of the author’s approaches consists in a detailed unbiased semantic analysis of the visual imagery of the 10-minute film Dog Barbos and Unusual Cross (1961), which previously was considered exclusively as a trick eccentric comedy. The author of the article proceeds from the culturological definition of Gaidai as a director who more explicitly than others rejected the serious and heroic discourse in the popular Soviet cinema of the 1960s and 1970s. The analysis of the images of the natural universe and their interaction with the characters reveals a hidden plot in the film — a journey into the depths of the unconscious and into a transitional zone, an otherworldly reality. The screen life of the characters is only partly a satire on the individual vices of ordinary citizens and an ironic view on the incapacity of the officialdom. The film creates a fantastic reality, which is a kind of privilege of the Coward, the Fool and the Pro. The author comes to the conclusion that Gaidai’s film extends beyond the genre of eccentric comedy and that its aesthetics has deep connections with myth and folklore.

Abstract. Several single-platform satellite missions have been
designed during the past decades in order to retrieve the atmospheric
concentrations of anthropogenic greenhouse gases (GHG), initiating worldwide
efforts towards better monitoring of their sources and sinks. To set up a
future operational system for anthropogenic GHG emission monitoring, both
revisit frequency and spatial resolution need to be improved. The Space
Carbon Observatory (SCARBO) project aims at significantly increasing the
revisit frequency of spaceborne GHG measurements, while reaching
state-of-the-art precision requirements, by implementing a concept of small
satellite constellation. It would accommodate a miniaturised GHG sensor
named NanoCarb coupled with an aerosol instrument, the multi-angle
polarimeter SPEXone. More specifically, the NanoCarb sensor is a static
Fabry–Pérot imaging interferometer with a 2.3×2.3 km2 spatial resolution and 200 km swath. It samples a truncated interferogram at optical path differences (OPDs) optimally sensitive to all the geophysical parameters necessary to retrieve column-averaged dry-air mole fractions of CO2 and CH4 (hereafter XCO2 and XCH4).
In this work, we present the Level 2 performance assessment of the concept proposed in the SCARBO project. We perform inverse radiative transfer to retrieve XCO2 and XCH4 directly from synthetic NanoCarb truncated interferograms and provide their systematic and random errors, column vertical sensitivities, and degrees of freedom as a function of five
scattering-error-critical atmospheric and observational parameters. We show
that NanoCarb XCO2 and XCH4 systematic retrieval errors can be greatly reduced with SPEXone posterior outputs used as improved prior
aerosol constraints. For two-thirds of the soundings, located at the centre
of the 200 km NanoCarb swath, XCO2 and XCH4 random errors span 0.5–1 ppm and 4–6 ppb, respectively, compliant with their respective 1 ppm
and 6 ppb precision objectives. Finally, these Level 2 performance results
are parameterised as a function of the explored scattering-error-critical
atmospheric and observational parameters in order to time-efficiently
compute extensive L2 error maps for future CO2 and CH4 flux
estimation performance studies.
Characteristics of Robust Mesoscale Eddies in the Gulf of Mexico
Authors: Zhu Yingli , Liang Xinfeng
Published: August 2022

Abstract. Although numerous studies on mesoscale eddies in the Gulf of Mexico (GoM) have been conducted, a comprehensive study on their temporal and spatial characteristics is still lacking. In this study, we combine three eddy detection algorithms to detect eddies from the 26-year sea surface height record in the GoM and examine their characteristics. We find distinct characteristics between Loop Current Eddies (LCEs), Loop Current Frontal Eddies (LCFEs), and mesoscale eddies that are not directly related to the Loop Current (LC). Seasonal variability appears in both the LCFEs and non-LCFE cyclonic eddies and shows large uncertainties. More specifically, more LCFEs are formed in January to July than in August to December, likely related to the seasonal variation of the northward penetration of the LC. And the formation of non-LCFE cyclonic eddies shows a biannual variability, which could be linked to the position and strength of the background current in the western GoM. Low-frequency (interannual to multidecadal) variability is also detected. In the eastern GoM, the extent of northward penetration of the LC can affect the generation of LCFEs and result in low-frequency variations. In the western GoM, the low-frequency variability of eddy occurrence and amplitude could be related to the surface circulation strength. This study can serve as an up-to-date reference for eddy-related investigations in the GoM.
