Authors: Anyanwu Emeka Donald , Orjikwe Chetachi Jane , Chinasa Precious Oluchi
Published: April 2022

Water quality and zooplankton assessment of a rural river in Southeast Nigeria was carried out between May 2019 and October 2019 in three stations in relation to anthropogenic activities. The major anthropogenic activity in the river was indiscriminate sand mining. The water samples were collected and analyzed using standard sampling and analytical procedures while zooplankton samples were collected using filtration method. pH and dissolved oxygen values were lower than acceptable limits while some of the biochemical oxygen demand values exceeded the acceptable limit. A total of 447 individuals from 25 zooplankton taxa and three major taxonomic groups were recorded. Copepoda was the dominant group (158 individuals/L), followed by Rotifera (147 individuals/L) and Cladocera (142 individuals/L). Spatially, station 1 had the highest abundance (159 individuals/L), followed by station 3 (152 individuals/L) and station 2 (136 individuals/L). The biodiversity indices (Shannon–Weiner and Margalef) were low while Evenness was high when compared with their respective ranges. This study has shown that the combined effects of season, sand mining and other activities have not adversely affected the water quality and zooplankton community. However, the community structure of the zooplankton groups gave an indication of a moderately polluted environment; attributable to the effects of season and human activities in the watershed. Sand mining is a major activity in the river and needs to be regulated to forestall any adverse effect on the water quality and biota in future as observed elsewhere.
Maximum Shannon Information Delivered in a Lecture
Authors: Alksne L. , Ozols A.
Published: April 2022

The aim of our paper is to evaluate the maximum Shannon (syntactic) information carried through a video lecture. To achieve the aim, we have considered a natural lecture delivered by a lecturer as a signal transmitted over the physical communication channel consisting of a sound sub-channel and light sub-channel. Receivers are eyes and ears of listeners whose physical characteristics are taken into account. The physiological, neurological and cognitive aspects of the problem are neglected in calculations. The method has been developed to calculate the absolute maximum values of Shannon information characteristics of a natural lecture basing on the capacity formula of continuous communication channel and physical considerations taken into account for the first time, to our knowledge. Maximum Shannon information characteristics (entropies of sound and light frames, amounts of total acoustical and optical information, capacities of sound and light sub-channels, total amount of information and total capacity) of a natural lecture perceived by the audience have been calculated. These values are the upper bounds of a video lecture. The obtained results are discussed in the paper. After some modification, the proposed method can be practically applied for the optimization of both natural and video lectures because there is some correlation between syntactic and semantic information characteristics.

Authors: Yang Hao , Fu Yuwen , Yang Jiansheng
Published: April 2022

Flame combustion diagnostics is a technique that uses different methods to diagnose the flame combustion process and study its physical and chemical basis. As one of the most important parameters of the combustion process, the flame equivalence ratio has a significant influence on the entire flame combustion, especially on the combustion efficiency and the emission of pollutants. Therefore, the measurement of the flame equivalence ratio has a huge impact on efficient combustion and environment protection. In view of this, several effective measuring methods were proposed, which were based on the different characteristics of flames radicals such as spectral properties. With the rapid growth of machine learning, more and more scholars applied it in the combustion diagnostics due to the excellent ability to fit parameters. This paper presents a review of various measuring techniques of hydrocarbon flame equivalent ratio and the applications of machine learning in combustion diagnostics, finally making a brief comparison between different measuring methods.

Avulsion Fracture of the Anterior Superior Iliac Spine in a Young Athlete Detected by Point-Of-Care Ultrasound
Authors: Mori Takaaki , Ihara Takateru , Nomura Osamu
Published: April 2022

Pelvic avulsion fractures (PAFs) are common in adolescents. X-ray is commonly used to diagnose PAF, but the use of point-of-care ultrasound (POCUS) for this purpose in pediatric emergency departments has yet to be published. We reported herein a pediatric case of anterior superior iliac spine (ASIS) avulsion fracture detected by POCUS. A 14-year-old male patient visited our emergency department for groin pain he experienced during a game of baseball. POCUS of the right ilium demonstrated a hyperechoic structure anterolaterally displaced towards the ASIS, suggesting an ASIS avulsion fracture. X-ray of the pelvis confirmed the findings and led to the diagnosis of ASIS avulsion fracture.
Impact of Point-of-Care Ultrasound in Medical Decision Making: Informing the Development of an Internal Medicine Global Health POCUS Curriculum
Authors: Fleshner Michelle , Fox Steve , Robertson Thomas , Fujita Ayako Wendy , Bhamidipati Divya
Published: April 2022

Background: Point-of-care Ultrasound (POCUS) is particularly useful in low-middle income countries (LMICs) where advanced imaging modalities and diagnostics are often unavailable. However, its use among Internal Medicine (IM) practitioners is limited and without standard curricula. This study describes POCUS scans performed by U.S. IM residents rotating in LMICs to provide recommendations for curriculum development.  Methods: IM residents within a global health track performed clinically-indicated POCUS scans at two sites. They logged their interpretations and whether or not the scan changed diagnosis or management. Scans were quality-assured by POCUS experts in the US to validate results. Using the criteria of prevalence, ease of learning, and impact, a framework was developed for a POCUS curriculum for IM practitioners within LMICs.  Results: A total of 256 studies were included in analysis. 237 (92.5%) answered the clinical question, 107 (41.8%) changed the diagnosis, and 106 (41.4%) changed management. The most frequently used applications were the Focused Assessment for Sonography for HIV associated TB (FASH) exam, finding fluid (pericardial effusion, pleural effusion, ascites), qualitative assessment of left ventricular function, and assessment for A-lines/B-lines/consolidation. The following scans met ease of learning criteria: FASH-basic, assessment of LV function, A-lines vs. B-lines, and finding fluid. Finding fluid and assessment of LV function changed diagnosis and management most frequently, greater than 50% of the time for each category.  Discussion/Conclusion: We recommend the following applications as highest yield for inclusion in a POCUS curriculum for IM practitioners within LMICs: finding fluid (pericardial effusion, pleural effusion, ascites) and assessment of gross LV function.

Published: April 2022

Background:

There is scarce evidence regarding focal resection surgery for super-refractory status epilepticus (SRSE), which is resistant to general anesthetic treatment over 24 h. We report two patients with SRSE, in whom good seizure outcomes were obtained following focal resection surgery.

Case Description:

Patient 1: A 58-year-old man who underwent left anterior temporal lobectomy with hippocampectomy at the age of 38 years after being diagnosed left medial temporal lobe epilepsy. After 19 years of surgery with no epileptic attacks, the patient developed SRSE. Electroencephalogram (EEG) demonstrated persistence of lateralized periodic discharges in the left frontotemporal region. On the 20thday after SRSE onset, resection of the frontal lobe and temporal lobe posterior to the resection cavity was performed. Patient 2: A 62-year-old man underwent craniotomy for anaplastic astrocytoma in the left frontal lobe at the age of 34 years. Since the age of 60 years, he developed SRSE 3 times over 1 and 1/12 years. On EEG, repeated ictal discharges were observed at the medial part of the left frontal region during the three SRSEs. Corresponding to the ictal EEG findings, high signals on diffusion-weighted magnetic resonance images and focal hypermetabolism on fluorodeoxyglucose-positron emission tomography were observed around the supplementary motor area, medial to the resection cavity. Resection surgery of the area was performed during the interictal period.

Conclusion:

Good seizure outcome was obtained in the two cases which provide additional support for the recent concept of focal resection surgery as an indication for SRSE.
Supratentorial ependymoma, zinc finger translocation-associated fusion positive, with extensive synaptophysin immunoreactivity arising from malignant transformation of clear cell ependymoma: A case report
Authors: Bethel Jacob A. , James Kenneth M. , Tavakoli Samon G. , Crownover Richard L. , Brenner Andrew J. , Papanastassiou Alexander M. , Gilbert Andrea R.
Published: April 2022

Background:

We describe a case of a supratentorial ependymoma, zinc finger translocation-associated (ZFTA) fusion positive with extensive synaptophysin immunoreactivity arising from malignant transformation of an ependymoma with clear cell features in a patient with long-term follow-up.

Case Description:

A 55-year-old woman presented with seizures and ataxia 15 years after an initial resection of a clear cell ependymoma, Grade 2. Imaging demonstrated an enhancing right paracentral mass and the patient underwent biopsy and resection. Microscopic analysis showed regions of the tumor with morphological and immunohistochemical features typical of ependymoma, including perivascular pseudorosettes and focal dot- like epithelial membrane antigen positivity, as well as high-grade features. In addition, the neoplasm contained large nodular regions of clear cells exhibiting extensive synaptophysin immunoreactivity, suggestive of neural differentiation, and only focally positive immunoreactivity for glial markers. Electron microscopy showed poorly formed and ill-defined junctional complexes, but no cilia, microvilli, or dense granules were seen. Molecular profiling revealed the presence of a fusion between ZFTA (previously known as C11orf95) and RELA fusion.

Conclusion:

We report a case of extensive synaptophysin immunoreactivity in a ZFTA-RELA fusion-positive ependymoma that had undergone malignant transformation from a clear cell ependymoma and has long-term follow-up, contributing to the assessment of prognostic significance of synaptophysin immunoreactivity in supratentorial ependymoma, ZFTA fusion positive.

Analysis of Aerosols
Authors: Baltensperger Urs
Published: April 2022

Atmospheric aerosols have recently attracted considerable attention due to their effects on climate, atmospheric chemistry, and health. This interest has triggered a variety of activities including the development of new analytical methods for a better characterization of atmospheric aerosol particles, some of which are presented here. Emphasis is laid on the description of methods for on-line and in situ analysis, since the analysis of many processes requires a good time resolution, and since in situ analysis methods are less prone to sampling artefacts.
Analytical Techniques for the in situ Measurement and Speciation of Trace Compounds in Natural Waters
Authors: Buffle Jacques , Tercier Mary-Lou , Parthasarathy Nalini , Wilkinson Kevin J.
Published: April 2022

A major research component of the analytical activities of the Analytical and Biophysical Environmental Chemistry group of the University of Geneva (CABE) is focused on the development of chemical sensors and mini or microanalytical systems for in situ measurements of trace compounds in aquatic environmental systems, including surface waters, sediments or water treatment plants. In this field, new concepts are required in order to determine not only the total concentration of environmental analytes but also the concentrations and physicochemical properties of their environmentally relevant chemical forms (chemical speciation). New selective analytical systems integrating reliable and rugged sensors with simple separation principles must be imagined to perform in situ (at depth), real-time, automatic measurements. Microtechnology is a key factor in such developments. New analytical methods must also be developed to characterize the nature and properties of the major natural, often colloidal or polymeric, complexing agents. In this context, the scientific approach of CABE is explained.
Analytical Chemistry in High-Alpine Environmental Research
Authors: Schwikowski Margit
Published: April 2022

Snow and ice chemistry studies in the high-altitude regions of the Alps give insight into present and past atmospheric chemistry. Impurities found in snow originate from atmospheric aerosol particles or reactive trace gases and, thus, represent a broad spectrum of chemical species such
as water-soluble inorganic and organic ions, insoluble minerals, organic components, soot, trace metals, etc. Consequently, a variety of analytical techniques need to be applied in snow chemistry studies, including ion chromatography, inductively coupled plasma optical emission or mass
spectrometry, atomic absorption spectrometry etc. A few details of the respective methods used in our laboratory are discussed here. Since snow samples are characterised by low impurity concentrations, they are particularly sensitive with respect to stability and contamination. Thus,
special care in sample handling is required. Investigations of the geographical, seasonal and year-to-year variations of the concentrations and deposition fluxes of major ionic species were carried out in the Alps. Concentrations of ammonium, nitrate and sulphate showed a West to East increase,
which was, however, not reflected in the total flux, since precipitation heights exhibited an opposite pattern. Long-term records from an alpine glacier revealed substantial increases of sulphate, ammonium, nitrate, and lead in the course of the last 100 years.
Detection and correction of delocalization errors for electron- and hole-polarons using density-corrected DFT
Authors: Rana Bhaskar , Coons Marc , Herbert John
Published: April 2022

Modeling of polaron defects is an important aspect of computational materials science but the description of unpaired spins in density functional theory (DFT) suffers from delocalization error. To diagnose and correct the over-delocalization of unpaired spins, we report an implementation of density-corrected (DC-)DFT and its analytic energy gradient. In this approach, an exchange-correlation functional is evaluated using a Hartree-Fock density rather than the DFT density, to incorporate correlation while avoiding self-interaction error. Results for an electron-polaron in TiO2 and a hole-polaron in Al-doped silica demonstrate that geometry optimization with semilocal functionals drives significant structural distortion including elongation of several bonds, such that subsequent single-point calculations with hybrid functionals fail to afford a localized defect even when hybrid functional optimizations do localize the polaron. This has significant implications for the traditional workflow in computational materials science. DC-DFT calculations provide a mechanism to detect situations where delocalization error is likely to affect the results.

Authors: Nayak Satya Prasad S P Sena , S Jayapala Rao G V
Published: April 2022

TA nanoparticle is a small particle whose size ranges between 1 to 100 nanometres at least in one dimension. Undetectable by the human eye, nanoparticles can exhibit significantly different physical and chemical properties compared to their larger material counterparts. This is due to a very large surface area to volume ratio when compared to bulk material. When the particle size goes to nanometer range quantum mechanical effects such as quantum confinement dominate the material properties.

Published: April 2022

Objetivo.Identificar los enfoques sobre la inocuidad y calidad del agua en los documentos que describen los programas de alimentación escolar en los países de América Latina y el Caribe (ALC).

Métodos.Estudio descriptivo, transversal y exploratorio de los documentos sobre alimentación escolar en los países y territorios de ALC. Se realizó el análisis documental y se determinaron a priori cuatro categorías: “agua para el consumo”, “agua para la higiene”, “agua para la preparación”, y “agricultura local/familiar” según el uso del agua en la alimentación escolar. Los documentos fueron buscados durante 2018-2019 en los sitios web oficiales de los países y territorios de ALC, la Organización de las Naciones Unidas para la Alimentación y Agricultura y el Programa Mundial de Alimentos. Se obtuvieron las frecuencias absolutas y relativas de los datos cuantitativos y para los datos cualitativos se aplicó el análisis de contenido del tipo temático.

Resultados.Se analizaron 114 documentos, de los cuales 29 eran elegibles. Los enfoques de las categorías “agua para el consumo”, “agua para la higiene” y “agua para la preparación” solo atribuían al agua la característica de ser potable. En la categoría “agricultura local/familiar” no se encontraron enfoques sobre el agua para el riego.

Conclusión.Los documentos abordan el agua, pero no se centran en su inocuidad y calidad. Los gobiernos y autoridades locales deben revisar sus documentos y garantizar la unanimidad de los enfoques a partir del apoyo y diálogo intersectorial para alcanzar las metas de los Objetivos de Desarrollo Sostenible.
El Estado trófico de las lagunas interiores de isla Barú durante la época climática seca de 2016
Authors: Arregocés Silva Liseth Johana
Published: April 2022

Las lagunas costeras son susceptibles a deterioro de la calidad del agua debido a factores ambientales y antrópicos. Playa Blanca -Isla Barú, además de estar ubicado en un parque natural, es uno de los principales atractivos turísticos de Cartagena, en el que muchos locales sustentan sus ingresos económicos. Durante la época climática seca del año 2016 se realizó un muestreo en cuatro lagunas costeras de la Isla, para determinar el índice de estado trófico o TSI (“Trophic State Index”) a partir de la concentración de Clorofila-a; así como, evaluar la calidad del agua. Para las estaciones de muestreo se realizaron mediciones de parámetros fisicoquímicos (temperatura, salinidad, oxígeno disuelto y pH) y se evaluaron parámetros biológicos (fitoplancton, coliformes fecales, E. coli, y pigmentos fotosintéticos). Elevadas concentraciones de clorofila a (2,225 – 640,800mg/m3) fueron registradas, asociadas a la alta densidad de organismos fitoplanctónicos particularmente Synechococcus sp., indicando florecimiento microalgal. En general, todas las lagunas registraron bajas concentraciones de oxígeno disuelto (0,01 – 4,51mg/L) y alta salinidad (47,10 – 171,00). Los parámetros microbiológicos sobrepasaron los límites permisibles acuerdo a la normatividad nacional (Decreto 1594 de 1984), indicando una baja calidad del agua. Los valores de TSI registrados corresponden a lagunas entre estado mesotrófico (33,33) a hipereutrófico (95,13). Se concluye que para el período muestreado las lagunas estudiadas se encontraron bajo procesos de eutrofización, siendo más evidente el deterioro ambiental en aquellas lagunas categorizadas como hipertrófica y eutrófica

acceptability of Ogi produced from four varieties of maize
Authors: Bolaji O.T. , Awonorin S.O. , Sanni L.O. , Adepoju P.A.
Published: April 2022

This study was aimed at investigating the common processing techniques and the effect on
consumers’ concerns (pasting, colour and sensory parameters) for ogi produced from four
varieties of maize (TZL COM4(A4W), ACR9931DMRSRY (C3Y), BR9928DMRSRY,
(B2Y) and ACR97COM1 (E9W). Ogi was produced during the soaking period in the
range of 12 to 96 hrs at an average soaking temperature of 28 and 65ºC, respectively. The
result revealed that there were significant differences (p<0.05) in the pasting properties.
The peak viscosities ranged from 165.01-184.174 RVU and 165.01-188.94 RVU for C3Y,
161.889-184.60 and 162.35-199.42 RVU for B2Y, 165.48- 187.86 and 165.811.202.62
RVU E9W soaked at 28 and 65°C, respectively. Higher values of Breakdown viscosity
were recorded for ogi produced at 60, 72, 84 and 96th hrs of soaking for maize varieties
B2Y and C3Y. The cooking time obtained was all less than 7 mins, while the pasting
temperature ranged from 75-84°C. There were significant differences (p<0.05) in the
sensory parameters evaluated. Ogi from A4W at the soaking period of 12 hrs was
favourably scored 6.90 and 7.40 for sourness. Ogi soaked at 28 and 65ºC was scored
higher for colour at 12th hr for all the varieties. The result indicated that the soaking period
and method prompted the lightness of Ogi produced from maize grains. The colour
changes were significantly higher in the yellow maize varieties B2Y and C3Y.

Published: April 2022

Fish and its products are a major part of the human diet because they are rich in highquality proteins and key nutrients for brain development. Maintaining freshness, quality
and hygiene are essential in the supply chain. The purpose of this study was to assess how
marketers are adopting hygienic practices in a particular fish market. A random sampling
technique was applied to a sample of 100 fish marketing personnel in every five major
marketplaces. Semi-structured interview schedule and observation method were used and
adequacy index of infrastructure facility, the extent of adoption of hygienic measures and
adoption measure for improved marketing practices were detected with descriptive
statistics, ANOVA, F test, correlation, and regression by using statistical SPSS 23. Overall
availability index in all five markets has shown high infrastructure availability in drainage
facility (71.0±0.47%) and electricity supplies (71.0±0.50%), whereas a very less
availability index in the washable floor (35.2±0.55%) and ground condition (44.0±0.54%).
Among all the nine hygienic practices featured, use of fish landing platform
(86.0±0.47%), use of clean polyethylene for a consumer (80.0±0.46%), and use of clean
water for washing fish (70.0±0.59%) were adopted by the majority of fish marketing
personnel. However, the least attention (less than 50% of the scoring index) related to the
adoption practices were observed to have the proper maintenance of waste disposal
(31.0±0.43%), ground conditions of approaches and surroundings (34.0±0.54%) and using
adequate ice before transportation (47.0±0.46%). The R2
value indicated that all the
variables together served as cause for 14.4% of the variation in the adoption level. The
major constraints among the marketing personnel were found as per the scoring index the
improper maintenance (67.0±8.8%), lack of technical guidance (66.0±24.6%) and
irregular market structure (65.0±22.4%), while handling of fish. Research showed that
educational level may considerably affect maintaining hygienic practices. In order to
obtain high-quality products from fish markets, there is an urgent need for continuous
training in good personal hygiene for fish marketing personnel. This study recommends
that appropriate mechanisms with the introduction of a grading system be adopted to
implement and monitor measures of hygiene practices of fish markets.

Authors: Liu Hongwu , Ge Sha
Published: April 2022

By combing relevant research on the development status of motor quotient and its evaluation system at home and abroad, this paper expounds and clarifies the future research direction of motor quotient as well as constructs a basic framework of motor quotient concept classification and evaluation-application system. Research found that first, the research on motor quotient abroad started earlier and has rich evaluation means, mainly focusing on the clinical diagnosis of preschool children’s development and the evaluation of motor development, but there is little discussion on the concept of motor quotient, only involving the discussion on sports quality and kinesthetic intelligence; applied research is mainly reflected in the fields of physical education and medical clinic. Second, there are many discussions on the concept and connotation of motor quotient in China. The research on evaluation system is gradually enriched, but most of it is used in the field of education, while that of practical application is almost bare. Third, the future research direction should focus on teenagers, carry out research from a multi-disciplinary perspective, broaden the research field, and enrich practical application.
Analyzing the Impact of Household Income Sources on Consumer Behavior in China – Based on Mental Accounting
Authors: Sun Rui
Published: April 2022

With the continuous development of the economy and society in China and the improvement of people’s living standards, the consumption behavior and consumption structure of families in China have undergone significant changes. As an important source and basis of consumption, income has an influence on consumption behavior. Based on the mental accounting theory in behavioral economics, this paper uses the data from China Family Panel Studies (CFPS) to examine the differential impact of different sources of income on the consumption demand of households in China from the micro level. In terms of theory, based on the basic assumption and fact of elasticity of consumer demand, the model directly assumes that there is mental accounting effect in household consumption behavior; that is, the marginal propensity to consume from different sources of income has a significant difference. By establishing a regression model to analyze the influence of different sources of income on consumption, the mental accounting effect of consumption among households in China is verified. According to the theoretical hypothesis and empirical tests, this paper provides policy suggestions for the government. The government should increase people’s disposable income. Increasing the proportion of transfer income and property income can diversify people’s sources of income and promote consumption as well as economic growth. Finally, the social security system should be improved to promote the consumption level of low-income families.

Authors: Yaroshevych R. , Kovalenko A.
Published: April 2022

Метою даної роботи є проведення аналізу технологій які зможуть забезпечити підвищення ефективності Тактильного Інтернету (ТІ) у комп'ютерних мережах. Концепція ТІ набула свого розвитку завдяки появі та розвитку технологій, що вимагають досить малої затримки при доставці даних. Це насамперед послуги з певними вимогами до інтерактивності. Зокрема, це можуть бути різноманітні системи управління, пов'язані з передачею тактильних відчуттів від виконавчих механізмів і сенсорів на органи управління. Для підвищення ефективності ТІ сьогодні розглядається низка перспективних технологій, наприклад, технологія взаємодії пристрій-пристрій, D2D (Device-to-Device), без використання базової станції, що дозволяє ефективно побудувати надщільні комп'ютерні мережі. Для побудови мереж з малими затримками великого значення набувають технології типу MEC (Mobile Edge Computing), програмно-конфігурованих мережах SDN (Software Defined Networks) та віртуалізації мережних функцій NFV (Network Functions Virtualization). Комп’ютерні мережі з низькими затримками, в основі яких лежить концепція Тактильного Інтернету, мають велике значення при виборі методу побудови комп’ютерних мереж. В даній статті розглянуто різні технології та проаналізовані основні переваги та проблеми означених технологій, які вимагають подальшого їх дослідження.

Background: Hypertension is a condition that causes a person to experience a drastic increase in blood pressure. Hypertension is often referred to as the silent killer because it can damage target organs such as the brain, eyes, kidneys, heart and arteries. Based on the cause, the increase in blood pressure can occur due to essential or primary hypertension such as high stress. The aim of this study was to estimate the relationship between high stress and hypertension in adults, with a meta-analysis of the primary study conducted by the previous authors.
Subjects and Method: This study is a meta-analysis using the PICO ie, population: adults; Intervention: high stress; Comparison: low stress; Result: hypertension. The articles used in this study were obtained from two databases, namely Pubmed and Google scholar. The keywords in the article search were “adults” AND “high stress” AND “low stress” AND “hypertension” cross-sectional or “Stress” AND “hypertension”. The included article is in full English with a cross-sectional study design for 2014 to 2021 and reports the adjusted odds ratio (aOR) in a multivariate analysis. Article selection using PRISMA flow chart. Article analysis using the Review Manager 5.3 application.
Results: 10 articles with a cross sectional study involving 3,436 adults from 4 continents namely Asia, Europe, Africa and America to be used as a systematic review and meta-analysis. The data collected showed that high stress had a relationship with the occurrence of hypertension in adults as much as 1.66 times compared to adults with low stress (aOR=1.66; 95%CI= 1.28 to 2.17; p= 0.002).
Conclusion: High stress has a relationship with hypertension in adults.
