The phenomenon of pollution by plastic waste is a public health problem in Burkina Faso. The ingestion of these plastic bags by domestic ruminants causes enormous losses to producers. Thus, to have the involvement of these producers in the management of plastic, this study was initiated to collect their perceptions (knowledge, attitudes and practices) on this scourge of plastic ingestion by farm animals. It was conducted from May to June 2021 and involved 60 producers living in the urban and peri-urban area of the commune of Dori in Burkina Faso. The interviews focused on the characterization of their farms (breeding system, livestock diversity, animal feeding); their knowledge of the phenomenon of ingestion of plastic bags by domestic ruminants and its impact (mortality and loss of income) on farms; attitudes, practices in the face of the scourge and their proposed solutions. The survey revealed that animal feed was based essentially on natural grazing at 77% with supplementation for a minority of farms (6%) (p < 0.001). In addition, the extensive system based on transhumance was the most widespread because it concerned 83% (50) of the producers (p < 0.001). The ingestion of plastic bags by the animals is perceived by the producers as one of the main causes of the mortalities recorded in their farms, however the causes seem to be external to the farming systems, in view of the solutions they recommend. Respondents know the symptoms of plastic ingestion (weight loss (43%), persistent bloating (31%) often accompanied by a hardening of the abdomen and diarrhea (13%), anorexia (12 %) and a runny nose (1%)), but which can be confused with other parasitoses, and have traditional practices for diagnosing it. The study suggests that special arrangements be made for a better awareness of the management of plastic bags in the environment, with the support of environmental and public health technicians, municipal and communal authorities of Dori.

Descripción de la composición y distribución de ictiofauna bentónica por medio de imágenes submarinas en las aguas interiores de la Reserva Nacional Katalalixar (Patagonia Central Chilena)
Authors: Pereda Femenias Raúl Eduardo , Gorny Matthias
Published: February 2023

Durante 2009, 2017 y 2018 se realizó un estudio sistemático taxonómico de la ictiofauna presente dentro de la Reserva Nacional Katalalixar (RNK), ubicada en el norte de la Patagonia central Chilena. El objetivo de este estudio fue determinar la distribución geográfica y batimétrica además de la composición de especies de peces bentónicos presentes en esta área geográfica. Los muestreos se llevaron a cabo en 32 estaciones mediante filmaciones submarinas con vehículos operados a control remoto (ROVs), entre los 10 y 220 m de profundidad, identificando las especies posteriormente en base a sus características morfológicas. Se registraron un total de 15 especies dentro de la RNK, encontrándose que más del 90% se distribuyen en todos los fiordos y canales de la Patagonia chilena, 79% en la ecorregión denominada Chiloé – Taitao (zona norte de los fiordos y canales australes), 71% en la ecorregión Kawésqar (zona central) y un 71% en la ecorregión Magallanes (zona sur). En la RNK se identificaron 6 especies de nototenidos, lo cual representó la familia más diversa, registrándose también números similares a otras partes de la Patagonia, considerando que existen entre 8 (Chiloé - Taitao, Kawésqar) y 12 (Magallanes) especies de esta familia en cada ecorregión. La especie Sebastes oculatus fue la especie más frecuente con registros en 11 estaciones (34.4%), y distribuido entre 20 y 220 m de profundidad. Los nototenidos también fueron frecuentes y se registraron en 11 estaciones igualmente (34%), pero exclusivamente en aguas someras entre 20 y 50 m de profundidad, la mayoría de las otras especies identificadas en este estudio fueron registradas en una sola estación. Los registros de este estudio amplifican el conocimiento sobre la distribución geográfica y batimétrica de los peces bentónicos de las aguas interiores de la Patagonia central Chilena, siendo un aporte significativo en el monitoreo de posibles cambios de estos parámetros en relación al actual cambio climático, brindando información relevante para el desarrollo de los instrumentos futuros de planificación y preservación de esta reserva nacional.

In uence of numerical diffusion on the growth rate of viscous ngers in the numerical implementation of the Peaceman model by the finite volume method
Authors: Apushkinskaya D. E. , Lazareva G. G. , Okishev V. A.
Published: February 2023

A numerical model of oil displacement by a mixture of water and polymer based on the Peaceman model is considered. Numerical experiments were carried out using the DuMux package, which is a software library designed for modeling nonstationary hydrodynamic problems in porous media. The software package uses the vertex-centered variant of finite volume method. The effect of diffusion on the growth rate of ''viscous fingers'' has been studied. The dependencies of the leading front velocity on the value of model diffusion are obtained for three viscosity models. It is shown that the effect of numerical diffusion on the growth rate of ''viscous fingers'' imposes limitations on calculations for small values of model diffusion.
Maslov complex germ and semiclassical contracted states in the Cauchy problem for the Schrödinger equation with delta potential
Authors: Shafarevich A. I. , Shchegortsova O. A.
Published: February 2023

We describe the semiclassical asymptotic behavior of the solution of the Cauchy problem for the Schrödinger equation with a delta potential localized on a surface of codimension 1. The Schrödinger operator with a delta potential is defined using the theory of extensions and is given by the boundary conditions on this surface. The initial data are selected as a narrow peak, which is a Gaussian packet localized in a small neighborhood of the point. To construct the asymptotics, we use the Maslov complex germ method. We describe the re ection of the complex germ from the carrier of the delta potential.
Existence of solution of a free boundary problem for reaction-diffusion systems
Authors: Younes G. A. , El Khatib N. , Volpert V. A.
Published: February 2023

In this paper, we prove the existence of solution of a novel free boundary problem for reaction-diffusion systems describing growth of biological tissues due to cell influx and proliferation. For this aim, we transform it into a problem with fixed boundary, through a change of variables. The new problem thus obtained has space and time dependent coeffcients with nonlinear terms. We then prove the existence of solution for the corresponding linear problem, and deduce the existence of solution for the nonlinear problem using the xed point theorem. Finally, we return to the problem with free boundary to conclude the existence of its solution.

Authors: Asnawi Aqdi Rofiq , Suharto Ahmad , Shahir Muhammad Badrun , Anggara Deki Ridho Adi , Hannah Hannah
Published: February 2023

The order of the verses and their coherence has been debated among orientalists in qur’anic structure studies. This article aims to reveal the coherence of surah Al-Dzariyat questioned by Richard Bell, regarding the correlation between the verses in the surah. The method of analysing this surah is Semitic Rhetorical Analysis (SRA), utilising the verses’ symmetry explanations from Muslim scholars’ interpretations. This library research adopts descriptive and content analysis methods for analysing data. As the result of the study, surah adz-Dzariyat consists of two passages and seven parts in mirror construction based on Semitic Rhetoric principles. The relation between the verses shows their coherence and excellent verses order without jumpy arrangement. Several groups of verses which at first appeared to be irregular became to appear orderly and have a specific connection which can be understood through Semitic Rhetoric principles. This analysis strengthens the miracles of the Qur’an and refutes various opinions that doubt how good the order of the verses of the Qur’an is.

Dengue Hemorrhagic Fever (DHF) in Tuban Regency was an important health problem. Bangilan sub-district is a sub-district in Tuban Regency which has high dengue cases. The Bangilan Health Center has not used mapping or spatial analysis in its surveillance activities for dengue cases. Disease mapping is useful in assisting surveillance activities and making it easier for us to find out the spread of the house index in each village area. The purpose of this study is to analyze the spatial house index with dengue cases in Bangilan District, Tuban Regency. This type of research is descriptive analytic. The population in this study is a house around DHF patients with a radius of 100 m from the patient's house in Bangilan District, with a total sample of 774 houses. The research variables were cases of DHF and house index. DHF cases in 2020-2022 were obtained from secondary data from the Bangilan Health Center, while the house index was obtained from the larvae survey results. The data were analyzed to determine the effect of the house index and dengue cases using the GeoDa application. The results showed that the average house index in Bangilan District was 20.8% which according to WHO was high. The pattern of spread of DHF cases is random with an Average Nearest Neighbor value = 1 and the results of Moran's Index (I) = 0.061, meaning that there is a strong spatial autocorrelation effect on the house index with DHF cases.

Lymphatic filariasis is an infectious disease caused by filarial worms and transmitted by mosquitoes. Pekalongan City is the highest filariasis endemic area caused by Wuchereria bancrofti in Central Java. This is indicated by the microfilaria rate of 2.8% in 2016. To reduce the number of filariasis cases, mass drug administration has been carried out since 2011. The aim of the study was to describe the epidemiology of the distribution of filariasis endemic areas, microfilaria rate, treatment coverage. mass and the correlation of sociodemographic factors with the incidence of filariasis. The research variables used secondary data in the form of filariasis cases, education, population density, gender and land use. Data analysis used Spearman's correlation. The results showed that cases of filariasis were spread across all districts with an increasing number of endemic areas during 2011-2016. Efforts to mass treatment have not been successful (mf rate > 1% and treatment coverage < 65%) and must be repeated in 2017-2019. Sociodemographic factors were not related to the incidence of clinical or chronic cases of filariasis. To accelerate the achievement of filariasis elimination, it is necessary to add vector control efforts in integrated filariasis management.

From COVID to Couch Potato: The Importance of Physical Activity Promotion and Education
Authors: Carek Stephen M.
Published: February 2023

For many, the lockdowns of the COVID-19 pandemic resulted in drastic behavior changes. While the immediate uncertainty and fear surrounding the initial lockdown has subsided, there are still significant changes to our daily lives and work that may have lasting impact on our health and well-being. One such change is the increase in physical inactivity and sedentarism, a result of decreased group activities, organized events, work and school from home mandates, and physical distancing. Physical inactivity represents one of the strongest modifiable risk factors for poor health outcomes and a preventable cause of early morbidity and mortality from many common chronic diseases. Overall, health care providers are inconsistent and often ineffective at screening and counseling patients on the benefits of regular physical activity. Additionally, there is very little structured curricula for medical learners to address physical inactivity and other lifestyle factors that contribute to the health of our patients. As we adjust to new social practices and behaviors as a result of the COVID-19 pandemic, it is critical that we emphasize the need for education, screening, evidence-based interventions, advocacy, and effective role modeling on the importance of physical activity for our patients, communities, and our own well-being.

SBS testing, all samples were examined by scanning electron microscopy
(SEM) to identify failure patterns. Three samples, one from each group,
were prepared to evaluate the chemical compositions of the materials.
Samples were prepared using plexiglass molds with a diameter of 10 mm
and a thickness of 2 mm. The materials were then examined with an energy
dispersive X-ray spectroscopy for surface elemental analysis. The values
obtained from the tests were evaluated as statistically significant (p
< 0.05). After SBS testing, the difference between all CBCs
was statistically significant in both compound groups. According to the
findings obtained from this study, it was concluded that MTA Cem LC had
the highest SBS values in both composite groups.

prospective pilot study where we included patients who have had anterior
and/or posterior colporrhaphy as day cases between November 2020 and
September 2022. Setting - UK DGH hospital urogynaecology department
Population: all patients who had anterior/ posterior colporrhaphy as day
cases between nov 2020 and sept 2022 Methods :Non-randomized, single
centre, prospective pilot study Main Outcome: Majority of patients were
able to remove their urinary catheters post operatively without
complications Measures: Outcomes were evaluated using patients’ feedback
respones Results: The data obtained was over 22 month peroid.The total
was a total of 81 patients with 61% of them having anterior repairs and
39% having posterior repairs. Ages of the participants ranged from 42
years to 89 years. 79 % of questionnaires were returned. 98% of the
enrolled patients would not prefer to wait for another admission date
where a bed will be available. 97% of our patients removed the urinary
catheter by themselves and found it to be easy. 88% of our patients
would not prefer to come to the hospital or have a nurse sent to their
homes to remove the catheter. 89 % of our patients would recommend this
service to a friend. Conclusion: Our Study demonstrated that removal of
patient’s own catheter following vaginal wall repairs is cost-saving and
highly acceptable to this cohort of patients
Hydrogen production in fixed-bed reactors with combined reformer-burner modules by steam-ethanol reforming at different temperatures
Authors: Chen Junjie
Published: February 2023

Use of ethanol is attracting increasing attention both as primary
feedstock and as an alternative to increase the feedstock flexibility in
a given unit. However, steam reforming of ethanol is not a straight
forward process. Equilibrium of the reaction is shifted towards the
production of hydrogen even at low temperature. However, in practice,
ethanol is also converted to ethylene. The present study is focused
primarily upon the production of hydrogen in fixed-bed reactors by
steam-ethanol reforming under different temperature conditions.
Computational fluid dynamics is used to model fluid flow, heat and mass
transfer, and chemical reactions. The governing integral equations are
solved for the conservation of mass, momentum, and energy and other
scalars such as laminar flow and chemical species. Steady-state analyses
are performed using computational fluid dynamics. The reaction rates are
computed by the laminar finite-rate model. The present study aims to
explore how to effectively produce hydrogen in fixed-bed reactors by
steam-ethanol reforming at different temperatures. Particular emphasis
is placed upon the effect of temperature on the transport and reaction
characteristics of fixed-bed reactors for polymer electrolyte membrane
fuel cell applications. The results indicate that under a thermodynamic
point of view, high temperatures and steam-ethanol molar ratios promote
hydrogen yield. Low ethylene content is obtained at high pressure and
low temperature. At high temperatures the contribution of steam
reforming reactions results in a marked increasing of overall enthalpy,
enhancing process endothermicity, whereas the exothermic contribution of
water-gas shift and methanation reactions reduces the external heat
supply and the overall energy penalty at lower temperature. Although the
equilibrium of the water-gas shift reaction favors the products
formation at lower temperatures, reaction kinetics are faster at higher
temperatures. The typical products distribution of ethanol steam
reforming reaction, according to thermodynamic evaluations, results in
considerable hydrogen production rates at higher temperatures and high
methane yields at lower temperatures. The majority of supported metals
as catalysts expresses better performance at high temperatures, and the
production of oxygenated products increases and the formation of coke is
thermodynamically favored at low temperatures. Low reaction temperatures
generally favor the Boudouard reaction mechanism while methane
decomposition is the main route at high temperatures.

Incorporating discrete choice experiments into long-term care insurance policy decisions: Evidence from China
Authors: CHEN Qian , MA Sang
Published: February 2023

Rapid population aging has prompted most emerging economies to consider
introducing long-term care insurance (LTCI) as part of a comprehensive
social health protection scheme. We examine discrete choice experiment
(DCE) evidence from LTCI and evaluate several relevant attributes,
including the elimination period, maximum monthly benefit, out-of-pocket
rate and annual premium. The study uses a mix logit model to elicit
respondents’ preferences and willingness to pay (WTP) for these
attributes of LTCI and uses physical health status to assess
heterogeneity in responses to insurance choice. We found that most
respondents would consider purchasing LTCI, with respondents most
preferring the following attributes: 1) a out-of-pocket rate of 25%, 2)
a maximum monthly benefit level of 2000 CNY (about 296 USD), and 3)
three months elimination period. The study can provide a reference for
further adjustments to the existing scheme, increasing residents’
willingness to participate in insurance and promoting the sustainable
development of long-term care insurance.
Design of gas turbine combustors for the reduction of nitrogen oxides emissions by heterogeneous catalysis
Authors: Chen Junjie
Published: February 2023

Flammable mixtures of most fuels are normally burned at relatively high
temperatures, which inherently results in the formation of substantial
emissions of nitrogen oxides. In the case of gas turbine combustors, the
formation of nitrogen oxides can be greatly reduced by limiting the
residence time of the combustion products in the combustion zone.
However, even under these circumstances, undesirable quantities of
nitrogen oxides are nevertheless produced. Additionally, limiting such
residence time makes it difficult to maintain stable combustion even
after ignition. The present study relates to the design of gas turbine
combustors for the reduction of nitrogen oxides emissions by
heterogeneous catalysis. Steady-steady simulations are performed using
computational fluid dynamics. The fluid viscosity, specific heat, and
thermal conductivity are calculated from a mass fraction weighted
average of species properties, and the specific heat of each species is
calculated using a piecewise polynomial fit of temperature. Natural
parameter continuation is performed by moving from one stationary
solution to another. Particular emphasis is placed upon the sustained
combustion of at least a portion of fuel under essentially adiabatic
conditions at a rate which surmounts the mass transfer limitation. The
results indicate that it is possible to achieve essentially adiabatic
combustion in the presence of a catalyst at a reaction rate many times
greater than the mass transfer limited rate. Flammable mixtures of
carbonaceous fuels normally burn at relatively high temperatures, and
substantial amounts of nitrogen oxides inevitably form if nitrogen is
present. Complete catalytic combustion of a target species can only
occur when oxygen gas is found in molar stoichiometric excess; a
condition which is easily met when the target species is present in
trace quantity in air. In combustion systems utilizing a catalyst, there
is little or no nitrogen oxides formed in a system which burns the fuel
at relatively low temperatures. In the mass transfer limited zone, the
reaction rate cannot be increased by increasing the activity of the
catalyst because catalytic activity is not determinative of the reaction
rate. Among the unique advantages of the catalytically supported thermal
combustion in the presence of a catalyst is the fact that mixtures of
fuel and air which are too fuel-lean for ordinary thermal combustion can
be burned efficiently.

A noval method of determining bias lights for spectral response measurement of GaAs multi-junction laser power converters and its applications

Published: February 2023

Quantitative electrical analysis of sub-cells is crucial for the
designing of high-efficiency GaAs multi-junction laser power converters
(MJLPCs). Spectral response (SR) measurement is the main mean of
characterizing the electrical performance of sub-cell. However, all the
sub-cells in GaAs MJLPCs have the same SR range, resulting that finding
suitable bias lights to make the sub-cells current-limited is difficult
for the SR measurement of GaAs MJLPCs. Here, we report a method of
determining bias lights for the SR measurement of GaAs MJLPCs based on
the variation rules of simulated short-circuit current densities with
wavelengths in the sub-cells of GaAs MJLPCs. The method of determining
bias lights is applicable to a variety of GaAs MJLPCs, including in
original state, at high temperature or after high-energy particles
irradiation. With the method of determining bias lights, the measured
external quantum efficiency (EQE) curves of the 1st cell, the 2nd cell
and the 3rd cell in a GaAs triple-junction LPC were successfully
obtained. The work is anticipated to provide guidelines for further
developments of high-efficiency and high-reliability III-V MJLPCs.
