Published: October 2023

BACKGROUND

Semivolatile organic compounds (SVOCs) comprise several different chemical families used mainly as additives in many everyday products. SVOCs can be released into the air as aerosols and deposit on particulate matter during use by dispersion, evaporation, or abrasion. Phthalates are SVOCs of growing concern due to their endocrine-disrupting effects. Human data on the absorption, distribution, metabolism, and excretion (ADME) of these compounds upon inhalation are almost nonexistent.

OBJECTIVE

The goal of this study is to develop a method for repeated inhalation exposures to SVOCs to characterize their ADME in humans.

METHODS

We will use diethylhexyl phthalate (DEHP), a major indoor air pollutant, as a model SVOC in this novel protocol. The Swiss official Commission on Ethics in Human Research, Canton de Vaud, approved the study on October 14, 2020 (project-ID 2020-01095). Participants (n=10) will be repeatedly exposed (2 short daily exposures over 4 days) to isotope-labeled DEHP (DEHP-d4) to distinguish administered exposures from background exposures. DEHP-d4 aerosols will be generated with a small, portable, aerosol-generating device. Participants will inhale DEHP-d4-containing aerosols themselves with this device at home. Air concentrations of the airborne phthalates will be less than or equal to their occupational exposure limit (OEL). DEHP-d4 and its metabolites will be quantified in urine and blood before, during, and after exposure.

RESULTS

Our developed device can generate DEHP-d4 aerosols with diameters of 2.5 μm or smaller and a mean DEHP-d4 mass of 1.4 (SD 0.2) μg per puff (n=6). As of May 2023, we have enrolled 5 participants.

CONCLUSIONS

The portable device can be used to generate phthalate aerosols for repeated exposure in human studies.

Published: October 2023

Background. Assessment of elderly’s health status, medical, social service and care needs becomes important under global aging of the population. The purpose of the study was to assess the social, psycho-emotional and physical states of elderly patients based on geriatric screening tool during the war in Ukraine. Material and methods. 400 patients aged 60–89 were interviewed using original "Geriatric Assessment" questionnaire for the period 2022–2023. The questionnaire included 40 questions to assess social status, cognitive, psycho-emotional and physical states, morbidity, and chronic problems. Results. Unfavorable social signs were revealed — living alone (35 %), poor financial support (35 %), limitations of social relations (20 %), and lack of cultural life (70 %) along with low monotonous physical activity (97 %). The high frequency of depressed mood (97 %), anxiety (74 %) and dyssomnia (87 %) evidenced the low resistance to war stress in elderly. A mo­derate decrease in memory was registered in 60 %, pronounced — in 13 % patients. Among the neurological symptoms, dizziness (74 %) and balance disorders (50 %) dominated. The majority of respondents indicated physical decline: general weakness — 88 %, fatigue — 97 %, legs weakness — 76 %, hands weakness — 71 %. Unintentional weight loss, an indirect marker of sarcopenia, was identified in 32 %, height reduction as a marker of bone loss in 48 %, repeated falls and fractures in 12 and 8 %, respectively. History of stroke, myocardial infarction, neoplasma and COVID-19 was associated with higher frequency of balance di­sorders, inability to climb stairs, general weakness, hands and legs weakness, and nutrition disorders. Аs the age increased, the number of symptoms per patient enlarged and was greater in women compared to men. Conclusions. A high frequency of physical, cognitive, psychoemotional and social state disorders was registered in elderly patients during the war, which requires the attention of society for their possible correction.

Emile-Eugène Burcker (1846-1908) was a French military pharmacist who carried out a successful research program on the application of the Friedel-Crafts method to the synthesis of acids, ketones, aldehydes, and glycols in the aromatic series, which finally culminated in his doctoral thesis. In particular, he was able to synthesize a significant number of new acetonic and ketonic acids characterized by the presence in their molecule of both the carbonyl group CO and the group COOH; thus, having the ability to react as ketones, forming salts, esters, and as ordinary acids, and everything also, under the influence of nascent hydrogen, of forming oxyacids or acid-alcohols. Some new compounds included benzoylpropionic acid, benzhydrylpropionic acid, phenyl propyl acetone, toluylpropionic acid, phenylcamphoric acid, etc. Burcker also established the best procedure for dosing KOH, as well as an improved version of the Kjeldahl method to determine the amount of nitrogen present in organic compounds.

Authors: Murti Nurul Kurnia , Waslan Kuswaya , Nuriyah Nuriyah
Published: October 2023

ABSTRACT

Background: Myopia is one of the most common types of eye refractive error in the world, where the image of an object that is too far away is focused right in front of the retina. As a result, the eyes will blur when you see objects that are far away. Decreased levels of vitamin D in the body are associated with an increase in the prevalence of myopia because vitamin D functions as an anti-hypertrophy of the ciliary muscle and is useful in the formation of collagen which is the main component of the sclera. Objectives: this study was to determine the effect of vitamin D levels on the incidence of myopia.Methods: This study uses a literature study approach with a scoping review study design using 12 articles according to the inclusion criteria set by the researcher. Results: Based on the results of the literature study, myopic patients tend to have lower serum vitamin D levels than non-myopic patients. Conclusions: The risk of myopia decreases as vitamin D levels increase, especially in childhood and adolescence, but not in old age and in children with preterm birth.

Keywords: Literatur Review, Myopia, Vitamin D

 

ABSTRAK

Latar Belakang: Miopia merupakan salah satu jenis kelainan refraksi mata terbanyak urutan pertama yang ada di dunia dimana bayangan benda  jaraknya terlalu jauh difokuskan tepat di depan retina. Akibatnya, mata akan kabur saat melihat benda yang jaraknya jauh. Penurunan kadar vitamin D di dalam tubuh dikaitkan dengan peningkatan prevelensi terjadinya miopia dikarenakan vitamin D berfungsi sebagai anti hipertrofi otot siliaris serta bermanfaat dalam pembentukan kolagen yang merupakan komponen utama dari sklera. Tujuan: untuk mengetahui pengaruh kadar vitamin D terhadap kejadian miopia. Metode: Penelitian ini menggunakan pendekatan studi literatur dengan desain studi scoping review menggunakan 12 artikel sesuai dengan kriteria inklusi yang telah ditetapkan peneliti. Hasil: Berdasarkan hasil studi literatur, penderita miopia cenderung memiliki kadar serum vitamin D yang lebih rendah dibandingkan dengan penderita non-miopia. Kesimpulan: Resiko terjadinya miopia akan menurun seiring dengan adanya peningkatan kadar

 

vitamin D terutama pada masa anak-anak dan remaja, tetapi tidak pada usia dewasa tua serta pada anak-anak dengan kelahiran prematur.

Published: October 2023

The purpose of this article is to encourage the professional community, especially police officers in Colombia, to reflect on personal financial practices and to analyze the relationship between inadequate economic habits and professional performance. In this sense, a quantitative paradigm with a descriptive and a relational phase is used, according to a survey applied to 1,233 policemen located in the Colombian regions of Santander, Norte de Santander, Arauca and Magdalena Medio, which contrasts the variables of financial education, personal finances and indebtedness. Likewise, it is identified that police officers have overcome a basic stage of financial literacy; however, a national strategy is required to strengthen this area of knowledge from police schools. On the other hand, it is established that police officers understand the risks of high indebtedness and it is detected that a high percentage of police officers have debits or over indebtedness. In addition, it was determined that their savings capacity is limited due to the financial demands generated by their work in places other than their residence.

Published: October 2023

Las personas con síndrome de Down presentan dificultades para la adquisición de conocimientos relacionados con la geometría, pues requiere de razonamiento y visión espacial. Por ello, los objetivos de este estudio fueron: (1) verificar si la enseñanza de la geometría a través de actividades con materiales manipulativos en entornos familiares ayuda a que los participantes adultos con SD evolucionen de un nivel de van Hiele a otro, y (2) conocer las dificultades que los participantes adultos con SD tienen a la hora de aprender conocimientos sobre geometría básica. Se trata de un estudio de casos exploratorio y descriptivo en el que participaron tres personas adultas. En él, los participantes realizaron actividades individuales y grupales en entornos familiares usando materiales manipulativos y siendo guiados por preguntas. Además, las actividades fueron estructuradas siguiendo el constructo teórico de van Hiele. Los resultados muestran que la metodología fue efectiva porque los tres participantes aumentaron sus conocimientos iniciales sobre geometría básica dentro del mismo nivel de van Hiele, o evolucionaron de nivel, y se detectaron las dificultades de aprendizaje que determinaron dicha evolución. Se discuten las contribuciones que la presente investigación puede tener para la formación del profesorado en las diferentes etapas educativas.

Depth-partitioning of particulate organic carbon composition in the rising and falling stages of the Amazon River
Authors: Rosengard Sarah , Moura Jose Mauro S. , Spencer Robert , Johnson Carl G , McNichol Ann P. , Steen Andrew D. , Galy Valier
Published: October 2023

The Amazon River mobilizes organic carbon across one of the world’s
largest terrestrial carbon reservoirs. Quantifying the sources of
particulate organic carbon (POC) to this flux is typically challenging
in large systems like the Amazon River due to hydrodynamic sorting of
sediments. Here, we analyze the composition of POC collected from
multiple total suspended sediment (TSS) profiles in the mainstem at
Óbidos, and surface samples from the Madeira, Solimões and Tapajós
Rivers. As hypothesized, TSS and POC concentrations in the mainstem
increased with depth and fit well to Rouse models for sediment sorting
by grain size. Coupling these profiles to Acoustic Doppler Current
Profiler discharge data, we estimate a large decrease in POC flux (from
540 to 370 kilograms per second) between the rising and falling stages
of Amazon River mainstem. The C/N ratio, stable and radiocarbon
signatures of bulk POC are less variable within the cross-section at
Óbidos, and suggest that riverine POC in the Amazon River is
predominantly soil-derived. However, smaller shifts in these
compositional metrics with depth, including leaf wax n-alkanes and fatty
acids, are consistent with the perspective that deeper and larger
particles carry fresher, less degraded organic matter sources (i.e.,
vegetation debris) through the mainstem. Overall, our cross-sectional
surveys at Óbidos highlight the importance of depth-specific sampling
for estimating riverine export fluxes. At the same time, they imply that
this approach to sampling is perhaps less essential with respect to
characterizing the composition of POC sources exported by the river.

Authors: Ковригина А.И.
Published: October 2023

Цель исследования – выявить доминирующие стратегии коммуникативного поведения представителей латиноамериканских стран на деловых переговорах, объективируемые соответствующими средствами испанского языка. Объект исследования – латиноамериканская модель деловых переговоров как одна из разновидностей испаноязычной деловой коммуникации, обладающая социально-культурной спецификой. В качестве источников примеров использован личный опыт автора в переводе деловых переговоров, видеозаписи переговоров, размещенные на платформе YouTube[210]. Применялся метод анализа литературных источников, метод включенного наблюдения, метод дискурс-анализа. В результате исследования выявлено, что для высококонтекстной полихронной латиноамериканской деловой культуры характерна повышенная эмоциональность, личностная ориентированность, необязательность, индивидуализм и строгая иерархия делового процесса; выделены наиболее частотные речевые средства репрезентации данных коммуникативно-релевантных культурных черт в дискурсе деловых переговоров.

The aim of the study is to identify dominant strategies of Latin American communicative behaviour in business negotiations, which are represented by means of the Spanish language. The object of the study is the Latin American model of business negotiations as one of the varieties of Spanish-language business communication with its sociocultural specificity. The sources of examples are personal experience of translation in negotiations, videos of business negotiations posted on the YouTube platform. The study has revealed that high context and polychronic Latin American business culture is characterized by its high emotionality, deep personal relationship, non-compliance, individualist and strict hierarchy of the business process; the most frequent language units representing these communicatively relevant cultural features in the discourse of business negotiations were identified.

Published: October 2023

Изменения во многих сферах человеческой среды обитания под влиянием различных факторов приводят к появлению новых явлений, а в языке – к появлению неологизмов для обозначения этих явлений. Цель исследования – определить когнитивную сущность неологизмов современного английского языка, зафиксированных онлайн изданиями авторитетных словарей. Научная новизна исследования определяется тем, что выявлены и представлены основные тенденции словообразования в современном английском языке, а также определена семантика производных слов. В результате доказано, что неологизмы, зафиксированные в онлайн словарях, можно разделить на три группы: полностью мотивированные производные слова, понимание значения которых возможно без контекста, частично мотивированные производные слова, для понимания значения которых необходим контекст и полностью немотивированные или идиоматичные производные слова, сложное значение которых может быть актуализовано только в развернутом контексте при дополнительном толковании.

New phenomena appear in different areas of human society under the influence of various factors which lead to the changes in language, i.e. to the appearance of neologisms to denote these phenomena. The purpose of the article is to determine the cognitive essence of neologisms in the modern English language recorded by online editions of authoritative dictionaries. The scientific novelty of the research is determined by the fact that the main trends of word-formation in modern English are described, as well as the semantics of derived words is identified. As a result, it is proved that the neologisms recorded in online dictionaries can be divided into three groups: fully motivated derivational words whose meaning can be understood without context, partially motivated derivational words whose meaning requires context, and fully unmotivated or idiomatic derivational words whose complex meaning can only be identified in an extended context with additional interpretation.

The low machinability of titanium alloys is determined by the physical, mechanical, and chemical properties of these materials and their mechanical characteristics. It is also evident in the hardened state of the material being processed during cutting, as well as in the initial state. This phenomenon is caused by thermodynamic parameters that determine the properties of titanium material at elevated temperatures. The peculiarities of the cutting and chip formation processes during titanium alloy machining are presented in this article. The peculiarity of the described approach is the analysis of the results of simulation modeling of cutting in Deform 2D software. It is proved that the frictional factor in the formation of the thermal characteristics of the cutting process, which arises as a result of the chip sliding along the tool, dominates the load factor (caused by force and deformation processes in the chip root). It has been established that the length of contact between the chips and the tool’s rake face has a certain tendency to change: the contact length first increases and then decreases with increasing cutting speed. An analysis of the dependence of the chip compression ratio on changes in cutting speed has shown that with an increase in cutting speed, the average value of the compression ratio practically does not change, but the amplitude of its oscillation increases significantly, which is equivalent to a change in the shear angle. This parameter changes dynamically due to the adiabatic nature of chip formation

Mathematical model for the calculation of the chemical composition of deposited metal with sufficient accuracy has been developed. The presented mathematical model has been developed taking into account shares of base and clad metal, the metal of the previous roll in the subsequent one, and the relative step of cladding. Based on the calculated composition of deposited metal by flux-cored wire it has been proved and experimentally confirmed that the required chemical composition of deposited metal is achieved in the second-third layer regardless of the surfacing step. Theoretically established and experimentally verified the effective relative step of cladding. The established relative pitch allows for minimizing waste when cladding with flux-cored wire. In this case, the cross-sectional area of the roll reinforcement after the finishing run will be minimal.

Purpose. A mathematical model to determine the two-dimensional thermoelastic state in a semi-infinite solid weakened by an internal crack under conditions of local heating is examined. Heat flux due to frictional heating on the local area of the body causes changes in temperature and stresses in the body, which significantly affects its strength, as it can lead to crack growth and local destruction. Therefore, the study of the problem of frictional heat is of practical interest. This paper proposes to investigate the stress-deformed state in the vicinity of the crack tip, depending on the crack placement. Methodology. The methods for studying the two-dimensional thermoelastic state of a body with cracks as stress concentrators are based on the method of complex variable function. Reducing the problem of stationary heat conduction and thermoelasticity to singular integral equations (SIE) of the first kind, the numerical solution by the method of mechanical quadrature was obtained. Findings. In this paper, we present graphical dependencies of stress intensity factors (SIF) at the crack tip on the angle orientation of the crack as well as forms of the intensity distribution of the local heat flux. The obtained results will be used later to determine the critical value of the intensity of the local heat flux from equations of limit equilibrium at which crack growth and the local destruction of the body occur. Originality. The scientific novelty lies in the fact that the solutions to two-dimensional problems of heat conduction and thermoelasticity for a half-plane containing a crack due to local heating by a heat flux were obtained. This would make it possible to obtain a comparative analysis of the intensity of thermal stresses around the top of the crack, depending on the form of distribution of the intensity of the heat flow on the surface of the body. Practical value. The practical value is the ability to extend our knowledge of the real situation in the thermoelastic elements of engineering structures with the crack that operate under conditions of heat stress (frictional heat) in various industries, particularly in mechanical engineering. The results of specific values of SIF at the crack tip in graphs may be useful in the development of sustainable modes of structural elements in terms of preventing the growth of cracks.
