Thermal Oscillations in Sea Ice and Soils
Authors:   , Ben-Shachar Nitay
Published: July 2021

We present mathematical analysis of temperature oscillations in depth-dependent media by investigating the thermodynamics of sea ice and of soils. Time-series temperature measurements from thermistor strings are common in both sea ice and soils and are used to study their properties, evolution, seepage flux and a host of interactions with their environment. We use numerical tools and perturbation theory to study the propagation of high frequency, small amplitude temperature oscillations through the in-homogeneous media using one dimensional models. Analytical tools for studying such thermal waves are derived.

In sea ice the absorption of solar radiation and oscillating air temperatures result in two distinct thermal wave propagation behaviours. At depths, stationary waves associated with in place solar heating are observed, whereas near the surface, travelling thermal waves are present due to the quick decay in the absorbed solar radiation and the oscillatory air temperatures. These are observed in thermistor string data taken in McMurdo Sound, Antarctica between 1996-2003. Using a variety of mathematical tools, the leading order behaviour of the diurnal temperature oscillation is approximated in terms of elementary functions and is compared with results from numerical simulations.

The thermodynamics of soils differ from sea ice in that all the solar radiation is absorbed at the upper boundary and water movement within the soil carries heat. Macroscale in-homogeneity in the advection-diffusion equation is considered and the thermal wave propagation characteristics are studied using a WKB approximation. The leading order behaviour is shown to reduce exactly to the Stallman equations, being the solution to the thermal wave propagation in a homogeneous soil with constant, uniform water flow. We use the leading order WKB expansion to estimate errors in the homogeneous soil assumption commonly made to estimate the seepage velocity and soil diffusivity. It is shown that the diffusivity estimations are relatively stable and provide reasonably accurate results, but the seepage velocity estimations incur significant errors that should be considered. A frequency dependence in the error leads us to suggest multi-frequency analysis for detection and further studies of the effects of in-homogeneous soil thermodynamics.

Background: Typhoid fever is spread by ingestion of contaminated food or water, which is linked to infrastructure; specifically, sewage and sanitation. In developing countries, infrastructure varies according to socioeconomic status (SES). Balochistan is the least developed province of Pakistan. Aims: To analyse the association between the clinical features of typhoid fever and socioeconomic status. Methods: A quantitative, cross-sectional study was conducted in Quetta, Balochistan, Pakistan. Between May and October 2017, 143 patients presented to tertiary care hospitals and private clinics with a complaint of fever lasting ~3 days, along with a clinical history of headache, malaise, diarrhoea or constipation, abdominal pain, dry cough, and anorexia. All patients had a positive blood culture for Salmonella enterica serotype Typhi. Eighteen patients dropped out of the study, leaving 125. Results: Seventy (56%) participants had low socioeconomic status (SES), 40 (32%) middle SES and 15( 12%) high SES. The strongest predictors of presenting with typhoid fever were patients’ clinical condition when presenting to health facilities, followed by SES. Most respondents had a treatment duration of 1–2 weeks. SES had a high impact on source of drinking water supply. Conclusion: The strongest predictor of reporting typhoid fever was the current clinical condition of the patients, followed closely by SES. The incidence of typhoid fever in the low SES patients was almost the same as in the middle and high SES patients. Patients with low SES were more susceptible to contracting typhoid fever due to poor health status and facilities.

Objective: The study evaluated the hypolipidemic and anti-inflammatory potential of the hydroalcoholic extract of P. Aculeata (HEPa/EtOAC) in Wistar rats fed with Westernized diet. Methods: The experiment was approved by the Ethics Committee (Federal University of Pernambuco-23076.027165 / 2010-21). The hydroalcoholic extract (HEPa/EtOAc) was obtained from the aerial parts of P. Aculeata and portioned by acetate/ethanol in different concentrations. 36 male Wistar rats were initially divided into two groups: Control (C, n = 6), fed a commercial diet (26g / 100g of protein; 63g / 100g of carbohydrates; 11g / 100g of lipids) and Westernized (W; n = 30) – fed an experimental diet (15g / 100g of protein; 51g / 100g of carbohydrates; 34 g/100g of lipids) receving water ad libitum. After 4 months of diet, W group was arbitrarily redistributed into six subgroups according to water supplementation, or different extracts concentrations: (n = 6 animals/group): W- distilled water (1mL/kg; po); WG – genfibrozil (140 mg/kg; p.o.); W35- 35 mg/kg; W70 – 70 mg /kg; p.o. and W140- 140 mg/kg; p.o for 30 days. The lipid profile and pro-inflammatory cytokines were analyzed. Results: The westernized diet caused dyslipidemia and the treatment with HEPa-EtOAc (140mg / kg), promoted a significant reduction in the concentration of pro-inflammatory cytokines, in total cholesterol, in the LDLc and serum triglycerides. Conclusion: The reduction of dyslipidemia and pro-inflammatory cytokines from the of P. Aculeata extract corroborate the ethnopharmacological potential of the plant, already used by the population for hypoglycemic purposes.

Objective: To identify the levels of severity of COVID-19 in individuals co-infected with the Human Immunodeficiency Virus (HIV). Methods: Expanded summary of the literature review type. The searches were carried out in the main databases of the BVS and CAPES. The above authors declare that they do not have conflict of interest in this study. Results: Most individuals were being treated with antiretrovirals (83-100%) and, therefore, most had a TCD4 lymphocyte count above 200 cells/µL and a viral load ranging between 67-100%. Comorbidities ranged from 33-70% and deaths from 0-14%. The severity picture was mostly mild, at a minimum proportion of 63%, not significantly differing from the population with COVID-19 in general, which on average remains in a mild symptomatic picture, around 80%. Therefore, the percentage of deaths and more severe levels of the disease were lower than expected due to the immune deficiency of HIV positive people. Conclusion: It is rash to make generalizations about the topic or to safely close the hypothesis that the immunosuppression of individuals with HIV, co-infected with SARS-CoV-2 has an increased risk to acquire the most severe form of COVID-19. This is because the studies found in the literature did not have a sample of participants significant enough.

Determination of Quality in Homemade Vinegars by Spectroscopy and Rheology Methods
Authors: ÖZTÜRK Muhittin
Published: July 2021

This study focused on the determination of quality characteristics of homemade organic vinegars (apple, red hawthorn and yellow hawthorn) which were produced with double fermentation (ethyl alcohol and acetic acid fermentation) method by spectroscopy (UV/Fourier transform infrared) and rheology technique. These absorbance peak values are associated with organic acids and phenolic compounds were determined as an important parameter in the quality evaluation of vinegars. It was determined that the flow curves of all vinegars are compatible with the non-Newtonian flow, which is the behaviour of thickening (dilatant) fluids. From the obtained results, it was thought that the antioxidant and anti-bacterial effect of yellow hawthorn vinegar would be higher due to its higher acetic acid and phenolic compound content compared to the others.
Impact of Biogenic Amines on the Growth of a Chlorella vulgaris Culture
Authors: Oleskin Alexander V. , Postnov Andrey L. , Boyang Cao
Published: July 2021

The present work aims to develop a new approach enabling biotechnologists to increase the yield of Chlorella vulgaris biomass by means of biogenic amines (serotonin, dopamine, and histamine) that are known to stimulate growth of various unicellular organisms. C. vulgaris strain ALP was cultivated in the light with constant aeration at 24oC in a minerals-containing medium. Experimental systems contained 1, 10, or 100 mM of dopamine, histamine, or serotonin. Algal cells were counted using a light microscope. Serotonin caused a slight increase in biomass yield at a concentration of 10 mM, but not at the other tested concentrations. 1 and 10 mM (but not 100 mM) dopamine increased the cell number in the C. vulgaris culture at early cultivation stages. Histamine is the most efficient growth stimulator at concentrations of 1 and 10 mM, but not at a concentration of 100 mM, which even proved inhibitory to the algal culture. The data obtained demonstrate that the neurochemicals exert a stimulatory influence on the growth of the Chlorella culture at relatively low (micromolar) concentrations. Since animals often produce biogenic amines in response to stress or injury, the data give grounds for the suggestion that planktonic algae can benefit, in terms of growth rate, from the substances released by stressed or wounded representatives of aquatic fauna. In biotechnological terms, the data obtained hold some promise with regard to developing a relatively economical technique of boosting Chlorella biomass production.
Avaliação do seguimento de lesões precursoras de câncer do colo do útero – uma revisão bibliográfica
Authors: Cavalcante Gabriela Henrique Oliveira , Reis Gilson Jácome dos
Published: July 2021

O câncer do colo do útero, também chamado de câncer cervical, está relacionado com a infecção de alguns tipos do Papilomavírus Humano (HPV) chamados oncogênicos. Este tipo de tumor é o quarto mais frequente na população feminina, com aproximadamente 570 mil novos casos por ano no mundo. Cerca de 7.5% da população feminina é acometida por este câncer e 311 mil mulheres evoluem para óbito. O exame preventivo (Papanicolau) é uma medida fundamental para detecção precoce de lesões precursoras e amplamente utilizado. Quando a lesão é diagnosticada precocemente o tratamento apresenta alto grau de cura. O rastreamento e acompanhamento destes casos são essenciais para evitar o surgimento de novos casos de câncer que implicam em tratamentos mais complexos e dispendiosos. Este estudo consiste em uma revisão bibliográfica referente a avaliação e condução do seguimento de lesões precursoras deste tipo de câncer. Os dados analisados evidenciam dificuldades encontradas pelas mulheres em agendar consultas de retorno após realização do exame preventivo, o que dificulta a implementação de ações imediatas para o tratamento. A perda de seguimento é um problema relevante e ocorre devido a fatores como a má interpretação de exames, resultando em repetição desnecessária do exame preventivo e atraso na realização de colposcopia e, consequentemente, do início de tratamento; ausência de seguimento em exames alterados; deficiência de orientação e encaminhamento oportuno destas mulheres. Para enfrentar tais desafios propõe-se que os serviços estejam organizados em rede, que inclui sistema de rastreamento conectado com o seguimento e tratamento adequado das mulheres que apresentem alterações nos exames preventivos. Também se faz necessário investigação sobre os motivos de não adesão das mulheres, controle de qualidade dos serviços de coleta e análise das amostras, avaliação de protocolos utilizados e busca ativa das pacientes para realização do exame Papanicolau.

Palavras-chave: Atenção à Saúde, exame Papanicolau, longitudinalidade, detecção precoce de câncer.

The heat flux and the associated space charge in a gas-discharge plasma can lead to a change in the properties of the corresponding electronic devices: a change in the kinetic coefficients and the temporal instability of their parameters. In devices with small transverse dimensions, the surface charge field, which significantly affects the space charge in the plasma, can also affect the current in the quasineutral plasma, changing the magnitude of the electric field component, which depends on the heat fluxes of the plasma. Knowledge of the analytical dependences of the component of the longitudinal electric field that provides the discharge current on the parameters of the plasma, the heat flux of electrons and its geometry makes it possible to estimate in detail the parameters of real plasma devices. Purpose. Obtain and analyze analytical expressions for the longitudinal electric field in a confined plasma in the ambipolar diffusion mode, taking into account the heat fluxes of electrons, the value of which depends on the frequency of collisions of electrons with atoms when approximated as a power-law velocity function. Results. The equations of electron balance are obtained in integral form for a bounded flat plasma with allowance for the heat flux of electrons. Practical significance. The calculation results make it possible to evaluate the effect of the heat flux of electrons of a low-temperature flat plasma with light and heavy ions on their electrical properties.

Abstract. In this work, the processes of interaction of ultra-wideband (UWB) pulses with the duration of 0.47 ns with layered dry snow cover are theoretically investigated. The layered structure of the snow cover was modeled on the basis of experimental data on the height and density profile of the snow cover, which were measured in field on the test plot of an agricultural field in the area of the village. Minino, Krasnoyarsk Territory from November 12, 2020 to March 21, 2021. It is shown that the snow water equivalent (SWE) can be estimated from the time delay of the pulse reflected from the snow-soil interface with the coefficient of determination (R2) R2 = 0.98 and the root-mean-square error (RMSE) RMSE = 5.6 mm in the case of thickness from 4-6 to 39cm and an average density from 0.21 to 0.37 g/cm3 of snow cover. It is shown that the average density of snow cover linearly depends on the amplitude ratio of impulses reflected from the boundaries, snow-soil and air-snow (R2 = 0.55, RMSE = 0.04 g/cm3). The established dependencies make it possible to estimate the height of the snow cover with R2 = 0.95, RMSE = 2.9 cm. The accuracy of the proposed method for measuring SWE, average density and height of snow cover should be further investigated depending on variations in temperature, moisture, density, and texture of frozen soil, as well as under different moisturized conditions of snow. The obtained results are particular relevance in connection with the possibility of implementing this remote sensing method from the UAV, which opens up the prospects for creating a technology for UWB radar mapping of the main characteristics of the snow cover for use in precision farming systems.

Published: July 2021

The article is devoted to actual issues of public finance – old-age income support and social security in the twenty-first century. For this reason, government has tried to guarantee old-age’s pension eligibility. In our country pension system is presented with three-level pension system, which join mandatory and voluntary components – solidary system (first level), compulsory accumulation system (not exist now) and private pension system. According to Ukrainian’s pension model, basic and minimum pensions are funded by solidary system or PAYG (“Pay-As-You-Go”) system. As the results, maintains of sufficient financial resources of Pension fund’s budget is very important for financial stability of pension system. The authors show the relationship between sufficient financial support for the elderly in Ukraine and the financial capacity of the solidarity pension system. It was found that in order to form a financially stability pension system, it is necessary to ensure a sufficient amount of own pension fund revenues and avoiding deficit of the Pension Fund’s budget. So, the main indicators of current PAYG system in Ukraine include the public pension expenditures and deficit of the Pension Fund. The article presents dynamics of revenues to the Pension Fund of Ukraine and structure of own pension fund revenues and allocations from the government budged. According to author’s research, the main source of revenue collection of the Pension fund’s budget in Ukraine is the budget’s transfers. О. Чеберяко, В. Бикова ISSN 2078-5860 ФОРМУВАННЯ РИНКОВОЇ ЕКОНОМІКИ В УКРАЇНІ. 2019. Вип. 41 480 The budget expenditures in the structure of income of the pension fund are also analyzed. The total amount of the government budget expenditures that are directed to financing the pension fund are about twenty percent. In our opinion, the key reasons of the “lack of own income” are the shadowing of the economy, the macroeconomic situation, the low minimum wage, the existence of a limit on the maximum amount of wages, which accrues percent of social contribution. As a conclusion, the authors suggest measures for solving the issue of “lack of own income” of the Pension Fund of Ukraine – rising the retirement age, labor market’s reforming, increasing insurance fees and implement compulsory accumulation system. The analytical materials and conclusions can be useful for following researches of finding solutions for achieving the financial stable Pay-You-Go system.

Published: July 2021

Modelling volatility has become increasingly important in recent times for its diverse implications. The main purpose of this paper is to examine the performance of volatility modelling using different models and their forecasting accuracy for the returns of Dhaka Stock Exchange (DSE) under different error distribution assumptions. Using the daily closing price of DSE from the period 27 January 2013 to 06 November 2017, this analysis has been done using Generalized Autoregressive Conditional Heteroscedastic (GARCH), Asymmetric Power Autoregressive Conditional Heteroscedastic (APARCH), Exponential Generalized Autoregressive Conditional Heteroscedastic (EGARCH), Threshold Generalized Autoregressive Conditional Heteroscedastic (TGARCH) and Integrated Generalized Autoregressive Conditional Heteroscedastic (IGARCH) models under both normal and student’s t error distribution. The study finds that ARMA (1,1)- TGARCH (1,1) is the most appropriate model for in-sample estimation accuracy under student’s t error distribution. The asymmetric effect captured by the parameter of ARMA (1,1) with TGARCH (1,1), APARCH (1,1) and EGARCH (1,1) models shows that negative shocks or bad news create more volatility than positive shocks or good news. The study also provides evidence that student’s t distribution for errors improves forecasting accuracy. With such an error distribution assumption, ARMA (1,1)-IGARCH (1,1) is considered the best for out-of-sample volatility forecasting.
