Authors: Nie Jing , Fang Yuan , Qiu Qi , Li Yuan , Zhao Lu , Liu Xiang , Li Xia
Published: June 2021

Background: Research evidence has shown that late life depression(LLD)and amnestic mild cognitive impairment(aMCI)are both related to dementia and usually accompanied by inflammatory dysregulation, but few studies have compared the levels of chemokines and cytokines between these two disorders. In this cross-sectional study, we aimed at identifying differences in neuro-inflammation between patients with prodromal stage of AD (amnestic mild cognitive impairment, aMCI; Late life depression LLD) and the normal controls (NC).Additionally, the potential association between cognitive function and cytokines characteristics was evaluated.Methods: Using Luminex assays,we simultaneously measured 29 cytokines,including 6 CXC chemokine ligand(CXCL5,CXCL6,CXCL8,CXCL9,CXCL11,CXCL16),15 CC chemokine ligand(CCL1, CCL2,CCL3,CCL7, CCL8, CCL11, CCL13,CCL15,CCL17, CCL19,CCL20, CCL23, CCL24, CCL25, CCL27), IL-1β, MIP-2, IFN-γ, VCAM-1, IL-2, IL-4, TNF-α and IL-6 in plasma of subjects. Demographics, cognitive function and lifestyle factors were also collected. All subjects(n=69, 23 each group)were age- and gender-matched outpatients with LLD or aMCI without dementia(based on DSM-IV criteria)and normal controls(NC)in community. The Chinese versions of Montreal Cognitive Assessment(MoCA) and neuropsychological test battery (NTB) were used to evaluate the cognitive function in participants.Results: LLD patients showed remarkably higher level of IL-6 than the aMCI and NC groups. We also observed five CC chemokines (CCL2,CCL17,CCL15, CCL13and CCL5) and four CXCs (CXCL5,CXCL6,CXCL16 and CXCL11) were decreased in patients with LLD. In addition, CXCL5 and VCAM-1 were correlated with age and clinical characteristic with gender difference. Importantly, using two parameters(IL-6 and CCL13) could effectively distinguish LLD from aMCI with an area under curve of 0.809(95% CI 0.68-0.93).Conclusion: Under conditions of neuro-inflammation, distinct dysregulated pro-inflammatory cytokine and chemokines were associated with patients with predementia stage LLD and aMCI.. Our study showed that the model based on the pro-inflammatory cytokine could distinguish LLD from aMCI. These novel findings will give new clues to provide new therapeutic target for intervention or a marker for two diseases with similar pre-dementia syndromes.
Impacts of Public Telecommunications Policy on Industrial Geography and Welfare
Authors: Chatti Walid , Abalala Turki
Published: June 2021

We include a clear distinction between transport and telecommunication infrastructures. We assume that public expenditure enables Information Technology Enabled Services to be traded abroad without the use of traditional transport modes. We show that the increase in the knowledge spillovers mainly related to mobile human capital and trade of services can develop industrialization in developing country, leading to less spatial inequalities. This latter must invest more in telecommunication than in transportation infrastructures to attract both industrial and knowledge activities. The welfare level will be improved for skilled workers in both countries when public policy decreases the cost of trading knowledge.
Engineered polyethersulfone membrane for well-dispersed silver nanoparticle impregnation at high loading: high water permeate flux and biofouling prevention
Authors: Mukherjee Mohana , Bandyopadhyaya Rajdip
Published: June 2021

We present a new method for impregnation of silver nanoparticles (Ag NPs) at high loading on polyethersulfone (PES) membrane's external surface, simultaneously retaining native membrane's porosity – to achieve a high water permeate flux without biofouling. This was possible by PES membrane's surface modification with acrylic acid (AA), finally leading to AA-Ag-PES membrane. AA-Ag-PES had a high (9.04%) Ag-NP loading selectively on membrane surface, as discrete, smaller (mean size: 20 nm) nanoparticles (NPs). In nonfunctionalized Ag-PES, aggregated (mean size: 70 nm) NPs, with lower Ag loading (0.73 wt.%) was obtained, with NP being present both on membrane surface and inside pores. Consequently, AA-Ag-PES could maintain similar water permeability and porosity (10,153.05 Lm−2 h−1bar−1 and 69.98%, respectively), as in native PES (11,368.74 Lm−2 h−1bar−1 and 68.86%, respectively); whereas both parameters dropped significantly for Ag-PES (4,869.66 Lm−2 h−1bar−1 and 49.02%, respectively). AA-Ag-PES also showed least flux reduction (7.7%) due to its anti-biofouling property and high flux recovery after usage and cleaning, compared to native PES and Ag-PES membrane's much higher flux reduction (54.29% and 36.7%, respectively). Hence, discrete NP impregnation, avoiding pore blockage, is key for achieving high water flux and anti-biofouling properties (in AA-Ag-PES), compared to non-functionalized Ag-PES, due to aggregated Ag-NPs inside its pores.
Association Between the Digital Clock Drawing Test and Neuropsychological Test Performance: Large Community-Based Prospective Cohort (Framingham Heart Study)
Authors: Yuan Jing , Libon David J , Karjadi Cody , Ang Alvin F A , Devine Sherral , Auerbach Sanford H , Au Rhoda , Lin Honghuang
Published: June 2021

Background

The Clock Drawing Test (CDT) has been widely used in clinic for cognitive assessment. Recently, a digital Clock Drawing Text (dCDT) that is able to capture the entire sequence of clock drawing behaviors was introduced. While a variety of domain-specific features can be derived from the dCDT, it has not yet been evaluated in a large community-based population whether the features derived from the dCDT correlate with cognitive function.

Objective

We aimed to investigate the association between dCDT features and cognitive performance across multiple domains.

Methods

Participants from the Framingham Heart Study, a large community-based cohort with longitudinal cognitive surveillance, who did not have dementia were included. Participants were administered both the dCDT and a standard protocol of neuropsychological tests that measured a wide range of cognitive functions. A total of 105 features were derived from the dCDT, and their associations with 18 neuropsychological tests were assessed with linear regression models adjusted for age and sex. Associations between a composite score from dCDT features were also assessed for associations with each neuropsychological test and cognitive status (clinically diagnosed mild cognitive impairment compared to normal cognition).

Results

The study included 2062 participants (age: mean 62, SD 13 years, 51.6% women), among whom 36 were diagnosed with mild cognitive impairment. Each neuropsychological test was associated with an average of 50 dCDT features. The composite scores derived from dCDT features were significantly associated with both neuropsychological tests and mild cognitive impairment.

Conclusions

The dCDT can potentially be used as a tool for cognitive assessment in large community-based populations.

Authors: Huang Ching-Chang , Chen Ying-Hsien , Hung Chi-Sheng , Lee Jen-Kuang , Hsu Tse-Pin , Wu Hui-Wen , Chuang Pao-Yu , Chen Ming-Fong , Ho Yi-Lwun
Published: June 2021

BACKGROUND

The association between short-term exposure to ambient air pollution and blood pressure has been inconsistent, as reported in the literature.

OBJECTIVE

This study aimed to investigate the relationship between short-term ambient air pollution exposure and patient-level home blood pressure (HBP).

METHODS

Patients with chronic cardiovascular diseases from a telehealth care program at a university-affiliated hospital were enrolled as the study population. HBP was measured by patients or their caregivers. Hourly meteorological data (including temperature, relative humidity, wind speed, and rainfall) and ambient air pollution monitoring data (including CO, NO2, particulate matter with a diameter of <10 µm, particulate matter with a diameter of <2.5 µm, and SO2) during the same time period were obtained from the Central Weather Bureau and the Environmental Protection Administration in Taiwan, respectively. A stepwise multivariate repeated generalized estimating equation model was used to assess the significant factors for predicting systolic and diastolic blood pressure (SBP and DBP).

RESULTS

A total of 253 patients and 110,715 HBP measurements were evaluated in this study. On multivariate analysis, demographic, clinical, meteorological factors, and air pollutants significantly affected the HBP (both SBP and DBP). All 5 air pollutants evaluated in this study showed a significant, nonlinear association with both home SBP and DBP. Compared with demographic and clinical factors, environmental factors (meteorological factors and air pollutants) played a minor yet significant role in the regulation of HBP.

CONCLUSIONS

Short-term exposure to ambient air pollution significantly affects HBP in patients with chronic cardiovascular disease.
Memories from the Future: The Historical Experience of the First World War and the Civil War in Soviet Propaganda of the 1920s and 1930s
Authors: Ulyanova Svetlana B.
Published: June 2021

The article deals with the historical experience of the First World War and the Russian Civil War as it was brought up in Soviet propaganda of the 1920s and 1930s; topic is thus the employment of a useful past in the production of ideas about future wars. The present research is based on a corpus of normative texts related to the assessment of the First World War and the Civil War in the late 1920s and 1930s (including periodicals, political writings, materials of the Communist Party) as well as archival documents about campaigns dedicated to the anniversaries of the First World War and the Civil War. Despite their proclaimed policy of peace, Soviet leaders spoke of a major future war as inevitable, and tried to anticipate its nature through comparison with conflicts of the recent past. In the Soviet information space of the 1920s and 1930s, the Great War was presented primarily from a socio-political perspective. Assessing the First World War as imperialist, Soviet propaganda emphasized that the future conflict would inevitably start as a counter-revolutionary war against the USSR. The Civil War became the main source of heroic military discourse, and was presented as a national war against external enemies. The future war was thereby imagined on the model of the foreign interventions of 1918-1920. The author analyzes this approach with the example of the Soviet campaign dedicated to the twentieth anniversary of the defense of Petrograd from Yudenich's troops in 1919.
Children’s Memories of the Leningrad Blockade in the Materials of the Central State Archive of the Udmurt Republic
Authors: Uvarov Sergey N.
Published: June 2021

The article offers the previously unpublished memoirs of eleven Leningrad residents who were children during the German blockade of the city. All of them were collected in 1998-1999 by Nina Aleksandrovna Koroleva, and are today kept in her collection in the Central State Archive of the Udmurt Republic. After the war, Nina Aleksandrovna came to live in Udmurtia, where she started to record memories about wartime. Conventionally, her documents can be divided into two groups. The first includes the memories of those who were evacuated to Udmurtia during the Great Patriotic War. The second group consists of memories of those who ended up in the republic after the end of the war. All documents are preserved in the author's edition. The memoirs reflect childhood impressions of the siege period. Their authors share their feelings from the beginning of the blockade, and report details of their daily life during the siege; they also reveal the coping strategies of the respective families. Descriptions of the labor conducted by children invite for conclusions about their contribution to the Soviet victory. Very emotional are the reports about the lifting of the blockade. Some memoirs contain details of the evacuation from Leningrad to the mainland. From the perspective of the history of everyday life, the publication of these memoirs expands our knowledge about the Great Patriotic War and, in particular, about the blockade of Leningrad.
Midwifery as the first official profession of women in Russia, 18th to early 20th centuries
Authors: Mitsyuk Natalia A. , Belova Anna V.
Published: June 2021

The authors study the institutionalization of midwife specialization among women in Russia in the period from the 18th through the early 20th centuries. The main sources are legislative acts, clerical documents, as well as reports on the activities of medical institutions and maternity departments. The authors use the approaches of gender history, and the concept of professionalization as developed by E. Freidson. Midwifery was the first area of womens work that was officially recognized by the state. There were three main stages on the way to professionalizing the midwifery profession among women. The first stage (covering the 18th century) is associated with attempts to study and systematize the activities of midwives. The practical experience of midwifes was actively sought by doctors whose theoretical knowledge was limited. The second stage of professionalization (corresponding to the first half of the 19th century) was associated with the normative regulation of midwife work and the formation of a professional hierarchy in midwifery. The third stage (comprising the second half of the 19th century and the early 20th century) saw a restriction of the midwives spheres of activity, as well as the active inclusion of male doctors in practical obstetrics and their rise to a dominant position. With the development of obstetric specialization, operative obstetrics, and the opening of maternity wards, midwives were relegated to a subordinate position in relation to doctors. In contrast to the United States and Western European countries, Russia did not have professional associations of midwives. Intra-professional communication was weak, and there was no corporate solidarity. In Soviet medicine, finally, the midwives subordinate place in relation to doctors was only cemented.
Leisure and Recreation in the Socio-Cultural Memory of Urban Women in the 1950 and 1960s Based on Materials from Volgograd
Authors: Bogdashina Irina V.
Published: June 2021

The article examines everyday practices of rest and leisure among urban women living in the city of Volgograd (Stalingrad) - a city that had been completely destroyed during the war. The goal of the present study is to identify specific characteristics in the everyday practices of women. The methodology combines comparative historical, biographical and aggregate methods. Interviews conducted along the empathy method made it possible to identify the sensual and emotional sides of the respondents' lives. The research is based on ego-documents (diaries, oral history), periodicals (magazines, newspapers), and statistics. The article discusses the concepts of free time and rest as preserved in the memory of townspeople, and also private and public forms of leisure. A major finding is that women's memory and texts reveal sensory and emotional experiences that can be used for the history of everyday life. This allows for an imagination of everyday life from a new angle. Domestic work took away the vast majority of women's free time, and given the cultural potential of the region was still underdeveloped, most city dwellers concentrated pastime activities on their homes. However, with the high workload of women at home and at work, it was leisure outside the home that remained one of the few ways for women to relax and recover from mental and physical stress. The everyday life of urban women in the 1950s and 1960s was characterized by a division of leisure in private and public forms.

Authors: Faria Adriene Vieira de , Barbosa Kássia de Paula , Costa Adriana Rodolfo , Silva Patricia Costa , Drumond Anailda Angélica Lana , França Janaína Borges de Azevedo , Silva Gilzângela Martins
Published: June 2021

Contextualización del tema: el frijol mungo es ampliamente cultivado en Asia y en Brasil, y ha surgido como una opción para el cultivo en el segundo cultivo en el Centro Oeste de Brasil, especialmente cuando se pretende la rotación con pastos; sin embargo, la aparición desigual y lenta de las plántulas de frijol mungo puede conducir a retrasos en el desarrollo del cultivo y perjudicar la posición final. 

 

Vacío de investigación: algunas de las condiciones que afectan al establecimiento inicial del cultivo son la profundidad de siembra y el tamaño de la semilla. Estos factores todavía están siendo discutidos en el entorno científico, especialmente para una cultura recientemente insertada en Brasil. 

 

Propósito del estudio: el objetivo fue evaluar el efecto del tamaño de las semillas y la estandarización de la profundidad de la siembra en el rendimiento de las plántulas de frijol mungo. 

 

Metodología: el ensayo se llevó a cabo en un Latossuelo Rojo, con clima Aw, precipitación media anual de 1300 mm y distribución bimodal. El diseño experimental utilizado fue completamente aleatorio, en un esquema factorial de 2 × 3 con 8 réplicas de 25 semillas, con un total de 48 parcelas. Los factores analizados fueron de los tamaños de semilla (3 y 4 mm) y tres profundidades de siembra (1, 2 y 3 cm). Se evaluó el índice de velocidad de emergencia (IVE), las plántulas no emergidas, las plántulas normales, la masa fresca, la masa seca y la longitud de las plántulas. Los datos se sometieron al análisis de varianza y, cuando se aplicaba una probabilidad significativa del 5%, se aplicó una prueba de Tukey para comparar los medios de los factores en estudio. 

 

Resultados y conclusiones: se verificó que, cuando se siembran a 1 cm de profundidad, las semillas de frijol mungo tienen IVE más bajo; sin embargo, obtuvieron un menor porcentaje de plántulas no relevantes para el estudio, y un mayor porcentaje de plántulas normales emergió a una profundidad de 3 cm. Por lo tanto, la profundidad más recomendada para la siembra de frijoles mungo fue de 2 cm, independientemente del tamaño de la semilla utilizada. Lo tamaño de semilla de 4 mm permitió el desarrollo de plántulas con mayor acumulación de materia seca.
The heat semigroup and equation related to a Bessel-type operators and the canonical Fourier Bessel transform
Authors: Sami Ghazouani , Jihed Sahbani
Published: June 2021

In this paper we study a translation operator associated with the
canonical Fourier Bessel transform
$\mathcal{F}_{\nu}^{\mathbf{m}}.$
We then use it to derive a convolution product and study some of its
important properties. As a direct application, we introduce the heat
semigroup generated by the Bessel-type operators
$$\Delta_{\nu}^{\mathbf{m}^{-1}}=\frac{d^{2}}{dx^{2}}+\left(
\frac{2\nu +1}{x}+2i
\frac{a}{b} x\right)
\frac{d}{dx}-\left(
\frac{a^{2}}{b^{2}}x^{2}-2i\left(
\nu +1\right)
\frac{a}{b}\right) $$ and use it to
solve the initial value problem for the heat equation governed by
$\Delta_{\nu}^{\mathbf{m}^{-1}}.$

Current trends and tasks of training of land management specialists
Authors: Kosinsky Vladimir , Burov Mikhail
Published: June 2021

In 2015-2016 the State University of Land Use Planning and land management faculties of higher educational institutions released the final mass enrollment of graduates who studied “engineer” qualification for five years. Starting from 2016-2017, bachelors and masters of land management began to leave the walls of the State University of Land Use Planning and land management departments of universities. Has the division into two parts - bachelor's and master's been justified? Basically, we can say that this is an international practice and we would not want to live separately from the international community, since we study foreigners from many countries of the world who want to receive education in a Western way; in addition, our students also study abroad.
But, unlike the Western baccalaureate, we remain specializations. There are profiles in the undergraduate program: land administration, land management, real estate cadastre, urban cadastre, land valuation, real estate valuation, and so on, that is students receive professional knowledge. Mastership is designed to deepen them. But it is absolutely not necessary to choose undergraduate and graduate programs in the same direction, it can be changed. If a student is not satisfied with the direction or specialization chosen before, he can correct it by studying another mastership program. One undoubted positive consequence of Russia's accession to the Bologna process is the simultaneous assumption of international obligations to maintain the wide accessibility of higher education regardless of financial situation of young people. Europe seeks to provide broad social protection in this area, where Russia has been catastrophically losing ground in recent years. The United States, with all its wealth, has never tried to positively solve this problem and is not going to accept the Bologna rules, and they have enough compelling arguments for this. First of all, do we need a bachelor degree? How will a master match with a candidate of science? Today, the heads of land surveying firms and companies, sociologists, professors of universities as well as educational and scientific institutions are discussing this problem.

Published: June 2021

Currently, the issues of the use and transfer of state land remain quite relevant in Lithuania. According to the data of January 1, 2019, more than 10 percent of the country's territory has not yet been formed and not authorized for use. A large proportion of unauthorized state land is located in major cities in the country. Only a few municipalities in Lithuania have detailed state land use planning. One of them is Panevėžys City Municipality, where, with the help of EU funds, detailed and special plans have been prepared for almost all state land and the municipality is actively looking for ways to encourage residents to become more actively involved in the process of land ownership or use. Detailed territorial planning documents for this municipality were prepared in three stages. Territories near public buildings, apartment buildings, former problem areas were planned. These plans are important for the development and renovation of engineering infrastructure, urban green spaces, management of residential areas, well-being of the population, and so on. Territorial planning documents are an important tool for the sustainable development of territories. The recent adjustment of the detailed plans is based on the principle of continuity. Effective real property management creates good conditions for investors, improvement of infrastructure and living conditions, replenishment of municipal budget and so on.

Published: June 2021

Private vehicles are high dominant mode of transport in Salem, India, since there is no any commuter personal exposure information on air pollution. This is the first pollutant exposure study in different private vehicles across Salem city. In this study, critical air pollutant of fine particulate matter, PM2.5, was measured. In addition, accumulation of CO2, concentration also assessed in closed vehicles. The measured vehicles were motorcycle, auto rickshaw, hatchback car, sedan car, sports utility vehicle car, and multi utility vehicle van. The four-wheeler (car and van) in-vehicle concentrations were assessed under four different ventilation conditions. Student?s t-test statistical analysis was carried out to determine the significance exposure level between the vehicles. It is observed that there is no statistically significant difference (p ? 0.05) between the vehicles of motorcycle and sedan, motorcycle and multi utility vehicle van, and auto rickshaw and sports utility vehicle for PM2.5 pollutant. A regression analysis shows a strong negative correlation between PM2.5 and CO2 concentration in an air-conditioning cars.
The Attenuation of Diabetic Nephropathy by Annexin A1 via Regulation of Lipid Metabolism through AMPK/PPARα/CPT1b Pathway
Authors: Wu Liang , Liu Changjie , Chang Dong-Yuan , Zhan Rui , Zhao Mingming , Lam Sin Man , Shui Guanghou , Zhao Ming-Hui , Zheng Lemin , Chen Min
Published: June 2021

Inflammation and abnormal
metabolism play important roles in the pathogenesis of diabetic nephropathy
(DN). Annexin A1 (ANXA1) contributes to inflammation resolution and improves
metabolism. Here, we assess the effects of ANXA1 in diabetic mice and proximal
tubular epithelial cells (PTECs) treated with high glucose plus palmitate acid
(HGPA), and explore the association of ANXA1 with lipid accumulation in DN
patients. It is found that ANXA1 deletion aggravates renal injuries, including
albuminuria, mesangial matrix expansion and tubulointerstitial lesions in
HFD/STZ-induced diabetic mice. ANXA1 deficiency promotes intra-renal lipid accumulation
and drives mitochondrial alterations in kidneys. In addition, Ac2-26, an ANXA1
mimetic peptide, has a therapeutic effect against
lipid toxicity in diabetic mice. In
HGPA-treated human PTECs, ANXA1 silencing causes FPR2/ALX-driven
deleterious effects, which suppress phosphorylated Thr172AMPK,
resulting in decreased PPARα and CPT1b expression and increased HGPA-induced
lipid accumulation, apoptosis and elevated expression of pro-inflammatory and pro-fibrotic
genes. Last but not least, the extent of lipid accumulation correlates with
renal function, and the level of tubulointerstitial ANXA1 expression correlates
with ectopic lipid deposition in kidneys of DN patients. These data demonstrate
that ANXA1 regulates lipid metabolism of PTECs to ameliorate disease
progression, hence it holds great potential as a therapeutic target for DN.

Authors: Bratz Vanessa Caroline , Fedosse Elenir , Montenegro Pedro García
Published: June 2021

Introdução: Apesar de diferentes esforços para a promoção da inclusão, adaptação e qualidade de vida de pessoas com deficiências (PcD) ainda há barreiras a serem vencidas, principalmente, as atitudinais; tais pessoas continuam sujeitas a diferentes graus e tipos de discriminação. Sabe-se que a formação profissional em Saúde, por exemplo - em Fonoaudiologia - implica em envolvimento com PcD; por isso, a conveniência de se realizar pesquisas, junto a estudantes, sobre esse tema. Objetivo: caracterizar e analisar percepções e atitudes de acadêmicos frente à PcD. Método: estudo exploratório, analítico e quantitativo, realizado por meio de um questionário online, elaborado exclusivamente para este, bem como pelo uso da The Multidimensional Attitudes Scale Toward Persons With Disabilities (MAS), adaptada, visando-se conhecer as percepções e as atitudes dos acadêmicos de Fonoaudiologia da Universidade Federal de Santa Maria, acerca de PcD. A coleta ocorreu entre dezembro de 2019 e março de 2020. Os resultados foram analisados por estatística descritiva. Resultados: participaram 36 estudantes; sendo a maioria do sexo feminino, advinda de escolas públicas e com pouco contato com PcD, anteriormente e durante a graduação. Prevaleceu a percepção de não se sentirem amplamente preparados para lidarem com PcD, revelando atitudes como: i) posicionamentos, por vezes, excludentes; ii) sentimentos de tensão, timidez, vergonha e impotência; iii) intenção para interação com PcD, mas comportamentos contraditórios em relação à mesma. Conclusão: as percepções e as atitudes dos acadêmicos, de modo geral, indicaram pouco contato e insuficiente formação relacionada às deficiências. Sugere-se mais estudos que analisem aspectos singulares da formação acadêmica voltada à PcD.

Polystyrene usage has risen significantly in recent years as a result of its wide variety of applications. The persistent consumer demand for polystyrene resulted in the accumulation of polystyrene waste in landfills, inducing environmental degradation. Since polystyrene is a petroleum-derived material, the increasing demand for it resulted in the depletion of petroleum, a non-renewable energy source. Research teams from all over the world have invented many methods for dealing with polystyrene waste, including recycling and energy regeneration. However, there are drawbacks to recycling methods, such as the fact that they need a lot of manpower in the separating procedure and pollute the water, reducing the process's sustainability. Because of these flaws, the experimenters have cantered their efforts on the energy harvesting approach. As petroleum is the primary component of polystyrene, the pyrolysis process for recovering fuel oil from polystyrene is an useful technology because the retrieved oil has a higher calorific value than commercially available gasoline. The current paper discusses polystyrene conversion technologies as well as the pyrolysis techniques for polystyrene, which generates end products such as oil, gas, and char. The impact of different processing parameters on the product yield has been addressed using more advanced techniques of conducting pyrolysis with a solvent.

The main objective of this work is to design a concentric three-cylinder heat exchanger for better heat movement, using a sum of four expansions to verify its hot presentation under similar boundary conditions. For this reason, the second creep condition is specified for robust dividers where the heat flow for the outer side divider is concentrated to achieve an adiabatic state while the dividers and inner vanes of the cylinder are coupled. The deltas for the outside and inside of the line are characterized as mass flow trees; The power source is marked as an outlet with a pressure factor. Flow programming is used to determine the movement of liquid and heat flow in the measurement zones. The applicable conditions are governed iteratively by the limited volume details with the SIMPLE calculation. The RNG-k-epsilon model is used for storm currents because the impact of eddies on strong currents is more accurate than the standard k-epsilon model and the second booster graph method is used for the deflection of the eruptive energy and the its propagation speed. The results show that computer examination of the liquid elements of a concentric three-tube heat exchanger with inclined scales at 45 ° C provides the circulation temperature, the speed of heat movement, and, in general, a coefficient of thermal movement. more than 11.74% higher than sloped blades are at 30 ° C and 28.96% higher than straight stairs, 9mm high and 42.22% higher than three tube heat exchangers concentric fins.

The aim of the study is to develop a spatial electromechanical model of a variable-length link for use in telescopic manipulators, anthropomorphic robots, exoskeletons, and in studying the human musculoskeletal system. The proposed link model has two massive absolutely solid sections at the ends and a weightless section of variable length located between them. The study was carried out using the methods of theoretical mechanics, electromechanics, mathematical modeling, engineering design, numerical methods for solving systems of ordinary differential equations, control theory, nonlinear dynamics, experimental methods, and empirical data on the biomechanical properties of the human musculoskeletal system. The reliability of the obtained results is substantiated by a rigorous use of the above-mentioned methods. As a result of the study, a system of Lagrange-Maxwell differential equations was written, and an electromechanical model of an anthropomorphic system was developed in the Matlab Simulink software package. With the specified geometric and inertial parameters of a variable-length link corresponding to an average person's leg lower part and the time corresponding to the single-support motion phase, the electric motors and reducing gears implementing the human musculoskeletal system link's biomechanical motion fragment are selected. All of the selected motors have a sufficient operating parameters margin. The trajectories of all generalized coordinates along which the anthropomorphic system performs its necessary motion are determined. The mechanism load diagrams are obtained. The control system for the motors is synthesized, and the positioning error is evaluated. The novelty of the approach is that the newly developed electromechanical models of controlled variable-length links have a wide range of applying the obtained results and can be used in designing anthropomorphic robots and comfortable new-generation exoskeletons. Thus, the electromechanical model of a variable-length link with the parameters corresponding to the average person's leg lower part has been developed. The electric drives and transmissions able to implement a motion close to the anthropomorphic one have been selected; its implementation has been demonstrated, and the numerical calculation results are given.

ObjectivesThe aim of this study was to compare the coverage of Japanese encephalitis (JE) immunization obtained from a recall survey and immunization registers at community health centers (CHCs) in Bali Province, Indonesia.MethodsA population-based survey was conducted, and random 2-staged selection of clusters of sub-villages was performed. The sample consisted of households with children aged 9 months to 15 years old. Interviews were carried out with carers to recall JE immunization status. The recall immunization status was considered valid when name, date, and confirmation of immunization were available in an immunization register at a CHC. Descriptive analysis was performed. The completeness of the information within immunization registers at CHCs was assessed.ResultsThe coverage of JE immunization obtained from the recall survey was 93.8% (95% confidence interval [CI], 92.8–94.9). It decreased to 74.9% (95% CI, 72.8–77.2) after being validated against immunization registers. The recall coverage of JE immunization was significantly higher than immunization register data suggested. This discrepancy varied from 6.5% to 36.4% across 6 districts; however, none of these districts achieved the recommended target coverage of 95%. The quality of immunization registers varied across CHCs.ConclusionThe use of an immunization register may result in underestimating the true coverage of vaccination programs, and its utilization for measuring immunization coverage requires further consideration.
SEMANTIC-SYNTACTIC COMPONENTS OF THE SITUATION FOR CONVEYING INFORMATION
Authors: Stupak Inna
Published: June 2021

Verbs of speech activity constitute a significant layer of verbal lexicon, which is characterized bya complex semantic structure. Depending on the nature of the semantic features, verbs of speechactivity are divided into three groups, one of which is represented byverbs to deliver information. In recentyears, there has been an increase in the frequency of use of verbs for conveying information indifferent literary styles. The aim of the study is to establish the most frequent verbs of this semanticsand to identify the specifics of their functioning in the situation for informational transmission on thematerial of German journalistic texts. The analysis of the to deliver information was carried out usingthe electronic corpus of the German language, which made it possible to trace the dynamics of theuse of 28 to deliver information, identify the four most frequent verbs and establish their semanticmodels. The situation for conveying information provides three obligatory semantic roles: agent,addressee and message.The analysis of the situation for conveying information with the verbs іnformieren, melden, mitteilen, berichten
revealed the asymmetry of the obligatory components at the semantic and syntactic levels. Explicit and elliptical implementation of required components depends on the semantics of the verbs.
The situation for conveying information with the verb is characterized at the syntactic level by the implementation of two semantic roles: addressee and message. The semantic role of agent in the situation for conveying information with the verbs berichten, melden, mitteilen is filled with a noun in a metonymic transfer of the type WHOLEPART, where the WHOLE is an institution, and PART is an employee or the head of this institution. The second mandatory component of the situation is addressee, who at the syntactic level has an explicit expression mainly with the verb іnformieren. In the situation with the verbs berichten, melden, mitteilen the semantic role of addressee is identified by the previous context. The third obligatory component of the situation for conveying information – the information that istransmitted – has both explicit and deictic expression. Verb semantics, communicative necessity and the principle of saving language efforts regulate the implementation of the obligatory semantic components of the situation for conveying information. The most significant component of the informational situation has an explicit expression. In general, the analyzed verbs are characterized by the possibility of shiftingthe focus of attention to any of the obligatory components.

Ez az ausztrál tanulmány azt vizsgálta, hogy a csomagolás elején található címkék és a termék egészségességére vonatkozó jelzések hogyan befolyásolják a termékválasztást és a fizetési hajlandóságot. A hipotézisek a következők voltak: a termék kiválasztása és a fizetési hajlandóság jobban korrelál az élelmiszer egészségességével, ha a termék egészségességét nem a napi beviteli értékekkel (csökkentett, vagyis reduktív típusú címkézés), hanem elsősorban csillagokkal, másodsorban színes jelzőlámpákkal jelzik (értelmező típusú címkézés); valamint hogy a táplálkozásra vonatkozó állításokat a vásárlók ritkán olvassák el.
