Electrolyte testing is often ordered clinically, especially important in patients treated in the intensive care unit (ICU). In addition to the requirement for the accuracy of results, the turnaround time testing also needs to be shortened to ensure care and treatment. Currently, laboratories can perform electrolyte tests on two systems, a blood gas analyzer and a routine biochemistry analyzer. This study aims to find the correlation between the results of electrolyte tests performed on blood gas analyzer and automatic biochemistry analyzer. The study was conducted on 910 patients who were assigned both arterial blood gas and electrolyte tests at the Laboratory Department - Hanoi Medical University Hospital. The results showed that a high correlation between electrolyte results performed on a blood gas machine and an automatic biochemistry analyzer (r: 0.751-0.874). The difference exceeded the allowable cut-off and depended on the concentration of these electrolytes in the blood. The mean differences of the concentrations of Na+, K+, and Cl- in the blood were 1.4254 [-4.233-7.084], -0.4874 [-1.337-0.363], and -0.8388 [-7.346-5.668], respectively. The difference in electrolyte results on the two systems is clinically significant, clinicians therefore should pay attention to the use of these test results.

Covid-19 disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), may lead to a severe inflammatory response or cytokine storm. Immune dysfunction in untreated Crohn’s disease may augment the risk for a severe inflammatory response to Covid-19. It is estimated that about 2% of severe children need to be hospitalised and the mortality rate is about 0.08%. Crohn’s disease most commonly occurs in the small intestine and the colon. It can affect any part of the gastrointestinal (GI) tract, from the mouth to the anus. Crohn’s patients on immunosuppressive medical therapy may encounter an increased SARS-CoV-2 infection risk. By contrast, immunosuppressive therapy may also have a potential benefit on clinical outcomes in Covid-19, since it may suppress not only mucosal inflammation but also the severe acute respiratory syndrome SARS-CoV-2-driven systemic inflammatory immune response. Adalimumab therapy can effectively treat both pediatric Crohn’s disease and multisystem inflammatory syndrome in children temporally associated with coronavirus disease 2019 infection. However, the management and follow-up plan still needs more consensus because it almost depends on steroids, adalimumab, and other drugs. Covid-19 in patients with Crohn’s disease has not been well documented in the literature. Therefore, in this study, the authors reported a case of a pediatric Crohn’s disease successfully treated with adalimumab after infected coronavirus 2 at Children’s Hospital No. 2 from September 7, 2021 to November 4, 2021.

The aim of this study was to optimise spray drying process parameters of curcumin nanosuspension. Method: an I-Optimal experimental model was designed by Design Expert software including 22 experiments. The independent variables were inlet temperature (oC), pump speed (ml/minute) and weight ratio of curcumin-loaded nanoparticles and carrier and nanoparticle; the dependent variables were particle size after redispersing (nm), polydispersity index, dispersion time (second) and spray drying yield. After the optimal parameters had been verified by experiments, some quality requirements of spray-dried powders were evaluated. Then the physical and chemical properties of curcumin in spray-dried powders were studied by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and fourier-transform infrared spectroscopy (FT-IR). Results: the optimal parameters were established with the inlet temperature of 140oC, the pump speed of 5 ml/minute, the weight ratio of carrier and nanoparticle of 2:1. The obtained results of verification experiments were highly repeatable and were similar to the predicted ones from the software. The comparison of XRD spectra between curcumin crystal and spray-dried powders showed that curcumin in spray-dried powders existed in amorphous form. Furthermore, DSC patterns and FT-IR spectra of curcumin crystal and spray-dried powder demonstrated that there were interactions among curcumin, chitosan and lipoid S100. Conclusion: nano curcumin powders have met the quality requirements of preparation in laboratory-scale. This is a platform for further research later and eventually put into industrial-scale production.

Malassezia species can cause serious dermatologic diseases in humans. Synthetic antifungal drugs, which have been usually utilised as a treatment for Malassezia-associated diseases, are belonged to the azole group. However, the hypersensitivity and resistance to synthetic drugs due to improper use are raising public concerns. Recently, the study of using herbal essential oils in the control of Malassezia fungus has attracted great attention from researchers. This study analysed and identified 19 compounds of Ocimum sanctum L. essential oil, where eugenol is the main composition in O. sanctum L. essential oil, accounting for 42.4%. O. sanctum L. essential oil showed strong activity against 3 strains of human skin fungi M. furfur VNF01, M. furfurATCC14521, and M. globosa VNG02 with a minimum inhibitory concentration (MIC) of 2.5 μl/ml. Using this concentration, 74.66-80.66% of tested yeast strains’ cell numbers were eliminated after a 20-minute treatment. The results suggested that the herbal O. sanctum L. essential oil could be a potential agent to develop cosmetic products including shampoo and cream for the prevention and treatment of Malassezia-associated diseases.

The emergence of the acute respiratory infection virus SARS-CoV-2 has spread the Covid-19 pandemic over the world. Identifying the risk factors relevant to Covid-19 clinical features, given the striking difference in the clinical symptoms observed from SARS-CoV-2 infected individuals, have become one of the primary concerns among scientists. It has been well-known that host factors such as older age and comorbidities are associated with higher severity. Recently, numerous case/control studies, simulations, docking, in silico prediction, and genome-wide association study (GWAS) performed in various human populationshave achieved many significant results. The reported genetic variants were mostly categorised into the SARS-CoV-2 entry pathway, host immune responses and ABO blood groups. Genetic variants or loci that may play a protective role, increase susceptibility or be associated with severity/mortality have been analysed in detail. Despite the results being all drawn through statistical analysis and simulation, the knowledge still deserves consideration as supporting materials for in-depth studies on the pathogenesis of Covid-19 and personalised medicine in the forthcoming years.

The study aims to examine the pathogenicity, the effects of environmental conditions on the growth of Aeromonas hydrophila in tilapia, and histopathological changes in infected fish. A. hydrophila isolates, which were recovered from diseased tilapia samples collected at farming cages/ponds in several northern Vietnam provinces, were identified by biochemical tests, PCR confirmation, and sequencing of 16S rRNA and housekeeping genes (gyrB). Three representative strains after identification were subjected to evaluate the pathogenicity via challenge experiments using the intraperitoneal injection method and to determine the impacts of environmental factors on their growth. The present study showed an average LD50 value (lethal dose 50%) of A. hydrophila to tilapia at 4.6×105 CFU/fish, the infected fish in the challenge tests presented the clinical and gross lesions similar to the natural diseased fish, including haemorrhaging at the base of fins, skin, anal opening and in visceral organs, especially in liver and intestine. Histopathological examination of the diseased fish showed the hyperplasia of epithelial cells and haemorrhage of the gill filaments. The tissues of the liver, kidney, and spleen exhibited the lesion of haemorrhage, congestion, and degeneration, while the brain tissue appeared the colonisation by the bacteria. The A. hydrophila strains from tilapia showed a high tolerance to environmental conditions with the capacity to survive and multiply at a temperature of 15-45°C, a salinity of 0-60‰ and a pH of 5-10. The present results provide useful information to establish the strategies in prevention of A. hydrophila infection in tilapia and other freshwater fish.

The immune response of two groups of selective breeding panagasius families: susceptible (or sensitive) (S) and resistant (R) family groups, including red blood cell count (RBC count), white blood cell count (WBC count), neutrophil (NEU), monocyte (MONO), lymphocyte (LYM), and melano-macrophage centers (MMCs) count in liver, kidney and spleen tissue and antibody titers (ABT) against the bacteria Edwardsiella ictaluriwere evaluated in this research. Fish were sampled at five truncated points after infection with the bacteria Edwardsiella ictaluri including before the challenge, 24, 48, 264, and 312 hpi. The immune response of the R group was more effective than that of the S group, showing: (1) RBC decreased less during the challenge; (2) WBC, NEU, MONO, LYM increased more rapidly, especially at the truncated point 24-48 hpi; (3) MMCs in liver, kidney, and spleen of the R group increased faster up to the truncated point 48 hpi while the S group increased more slowly and only up to the truncated point 24 hpi; (4) ABT were higher in all stages of the challenge. The research developed a multivariable logistic regression model with immune markers such as NEU, ABT and MMCs in the liver at the truncated point of 24-48 hpi to identify individuals which were resistant to Enteric Septicemia of Catfish (ESC), with sensitivity and specificity of 91.7, 95.0%, respectively.
Charmonium radiative decays within the covariant confined quark model
Authors: Ganbold Gurjav
Published: May 2022

We have studied the dominant one-photon radiative transitions of the charmonium ground and orbitally excited states within an analytic confinement model. Along with two fixed basic model parameters (mc and the cutoff value λ), we introduced only one adjustable parameter common to charmonium states: ηc, J/ψ, χc0, χc1, hc and χc2 to parameterize the quark distribution inside the hadron. Our estimates are in good agreement with the latest data.
Preserving the Wonder of Stories: The Role of Reflection in Reading Education in Library and Information Science Programs
Authors: Dali Keren , Hohmann Garrett
Published: May 2022

Building on the concept of transformative learning and exploring the role of reflection in graduate professional education, this article uses student and educator reflections from the graduate course on reading practices to narrate four stories of learning. These stories, structured based on the “4Ls” model of reflection, describe what was Learned and Liked in the course and what both the student and the educator Lacked and Longed for as a result of the course. An argument is made in support of not limiting Library and Information Science reading education to techniques and skills for providing reading suggestions (i.e., readers’ advisory) but for enriching this education with reflective exercises, a theoretical foundation of reading behaviors, and challenging intellectual and affective engagements that will contribute to a well-rounded practitioner education that facilitates the reading experience.
Perfil epidemiológico da doença de Chagas aguda no Brasil entre 2009-2019
Authors: Martins Isadora Florentino , Costa Alexandre de Pina
Published: May 2022

Este estudo teve como objetivo realizar uma análise epidemiológica de casos da Doença de Chagas registrados pelo Departamento de Informática do Sistema Único de Saúde (DATASUS) no Brasil no período compreendido entre 2009 a 2019. Nas quais as variáveis aplicadas foram: ano, mês, região de notificação, modo provável de infecção, faixa etária, gênero e evolução. No período estudado foram registrados, no território brasileiro, 2.821 casos confirmados da Doença de Chagas, onde foi possível observar uma crescente número de casos. O ano de 2018 destacou-se como o de maior incidência até o atual momento, tendo como modo provável de infecção a transmissão via oral que representou 85,6% das notificações totais, com evidência a partir do ano de 2014 e sendo o açaí o causador dessa mudança no cenário de transmissão. A curva epidemiológica de notificações por mês evidenciou um padrão de distribuição sazonal, devido os picos nos meses de outubro e declives durante os meses de março, correferindo com as características do vetor e safras de açaí. As maiores taxas de incidência ao longo dos anos ocorreram na Região Norte, onde apresentou 98,8% no ano de 2016, fato esse justificado devido ao alto consumo do fruto no estado do Pará. Os indivíduos mais acometidos foram os do sexo masculino, em uma faixa etária compreendida entre 20-59 anos, sendo esta a população economicamente ativa. Apesar das variáveis com valores espantosos, 1,45% dos pacientes chagásico evoluíram para óbito evidenciando a baixa relação da doença de Chagas com a mortalidade. É necessário reconhecer a amplitude do quadro e atuar em diferentes frentes para que estes índices diminuam. Sendo notório a estruturação de uma vigilância epidemiológica e sanitária na região mais acometida, a necessidade de ações de conscientização e educação para a população.

Published: May 2022

A dermatite atópica canina é uma doença alérgica pruriginosa, sendo considerada a principal dermatopatia crônica entre os cães. Os cuidados são para o resto da vida do animal e se não tratada adequadamente pode causar sofrimento para o cão e, até mesmo, para o tutor. Dessa forma, é de extrema importância que o médico veterinário tenha conhecimento das alternativas terapêuticas disponíveis, bem como os malefícios e benefícios que o medicamento pode proporcionar. Para isso, realizou-se um estudo descritivo analítico através de pesquisa bibliográfica indexada utilizando-se plataformas digitais de acesso como Periódicos Capes, PubMed, Science Direct, Scielo, Biblioteca Virtual em Saúde-MS e PubMed Central elaborando uma revisão de literatura sobre fatores desencadeantes, os sinais clínicos e os principais tratamentos da dermatite atópica em cães. Como resultados pode-se inferir que o tratamento não depende apenas de um medicamento e varia para cada fase da doença e para cada animal, além disso também pode ser influenciado pela condição financeira do tutor.
Surface Charge Characteristics of Bacillus Subtilis NRS-762 Cells
Authors: Ng Wenfa
Published: May 2022

Bacterial cell surface carries an electrical charge due to the myriad functional groups present, as well as assortment of ions and molecules non-specifically adsorbed to the cell surface. Thus, solution in contact with the bacterial cell surface play a critical role in influencing the overall surface charge characteristics through conferring non-specifically adsorbed ions and molecules. Various wash buffers are commonly used in removing non-specifically adsorbed ions and molecules for revealing the real surface charge of the bacterium. Using electrophoretic mobility measurement of zeta potential, this study attempted to understand the surface charge characteristics of Bacillus subtilis NRS-762 (ATCC 8473) with the help of three wash buffers: deionized (DI) water, 0.1M sodium nitrate, and 9 g/L sodium chloride. Experiment results revealed that B. subtilis NRS-762 was negatively charged over the entire pH range from 1.5 to 12. Specifically, with deionized water as wash buffer, the point-of-zero-charge (pHzpc) was at pH 1.5, which indicated that large amount of negatively charged functional groups were present on the cell surface. Comparison between the zeta potential-pH profiles of B. subtilis NRS-762 cultivated at 30 oC and 37 oC revealed that the profile for growth at 37 oC was more negatively charged over the entire pH range compared to that for growth at 30 oC. This highlighted that physiological adaptation might had occurred on the cell surface for coping with growth at a higher temperature. Zeta potential-pH profiles obtained revealed that DI water could not remove significant quantities of the non-specifically adsorbed ions and molecules. On the other hand, the zeta potential-pH profiles of cells washed with 0.1M sodium nitrate and 9 g/L sodium chloride overlapped each other substantially and were more negatively charged over the pH range from 2 to 11, compared to that of cells washed with DI water. This revealed substantial removal of non-specifically adsorbed ions and molecules with the use of 0.1M sodium nitrate (0.1M ionic strength) and 9 g/L sodium chloride (0.15M ionic strength), which helped reveal the actual surface charge of B. subtilis NRS-762 cells. Collectively, actual surface charge of B. subtilis NRS-762 was masked by non-specifically adsorbed ions and molecules, which could be removed by 0.1M sodium nitrate and 9 g/L sodium chloride wash buffer. Thus, in the case of B. subtilis NRS-762, 0.1M ionic strength wash buffer was the threshold at which there was complete removal of non-specifically adsorbed ions and molecules from the cell surface.

Ecological data of isopods (Crustacea: Oniscidea) in laurel
forests from the Western Canary Islands
Authors: Arndt Erik , Mattern Dirk
Published: May 2022

Isopoda were examined in different laurel forests of the Western
Canary Islands La Gomera, El Hierro, and La Palma using data from pitfall traps
and soil samples. Eleven species were recorded. The species communities from
forests of La Gomera and El Hierro on one side and La Palma on the other side are extremely different in spite of the similar forest structure, tree vegetation and
climatic conditions on the three islands. La Gomera and El Hierro are dominated
by the native Porcellio meridionalis which reaches greatest abundance in cool
and moist localities above 1200m a.s.l. All forest sites on La Palma are dominated
by Armadillidium vulgare, often accompanied by small endogean
Trichoniscidae. Five recorded species have been introduced to the islands by
man in historical time. These invasives dominate quantitatively in many study
sites, the average ratio of invasive:native specimens was 3.1:1 in pitfall traps
and 1.1:1 in soil samples. Climatic parameters seem to strongly affect the
invasion success. The most frequent invading species, A. vulgare and Eluma
caelatum, occur in highest abundances in warmer forest plots at lower altitudes
but are not able to dominate the cooler sites with low potential insolation.

Assessment of clinical conditions associated with Mondor disease
Authors: Ito Hiroshi , Ogawa Yasuhiro , Shimojo Nobutake , Kawano Satoru
Published: May 2022

BACKGROUND: Mondor disease is superficial thrombophlebitis of the thoracoabdominal wall, mid-upper arm, and penis. Although it is usually a benign disease requiring no specific treatment, little is known about this disease owing to its rarity. OBJECTIVE: The aim of this retrospective observational study was to investigate the epidemiology and prognosis of Mondor disease. METHODS: We conducted a single-center observational study of patients with Mondor disease. Patients who received a diagnosis of Mondor disease between 2015 and 2020 were analyzed. The patients’ medical records were manually reviewed to obtain the following variables: date of diagnosis, patient’s age, sex, department of diagnosing physicians, underlying diseases, medications, surgery, and time until resolution of the lesion. We also reviewed the 1-year mortality, 1-year occurrence of malignancy, and recurrence of Mondor disease. RESULTS: 20 patients were included in the study. The age of the patients ranged from 7 to 83 years, with a median of 47.5 years. Most of the patients presented with thoracoabdominal wall lesions. The underlying conditions included skin diseases, surgical procedures, breast cancer, smoking, and collagenous diseases, although more than half of the patients did not have plausible predisposing factors. About three-quarters of the patients saw a spontaneous resolution of the lesions within 4 weeks without medical or surgical treatments. CONCLUSIONS: Considering the good prognosis of this disease, it is essential to avoid unnecessary invasive tests or treatment once the diagnosis is confirmed.

Published: May 2022

BACKGROUND:

Abundant germplasm resources of Vaccinium uliginosum are present in Changbai Mountain in China, which have considerable research and development value. They include the naturally distributed alpine V. uliginosum, the white-fruited V. uliginosum variety, and various fruit shapes dominated by ellipses. However, the relevant research is limited, and the taxonomic status of various specific germplasm resources has not been addressed.

OBJECTIVE:

The genetic relationship and taxonomic status of four species of V. uliginosum germplasm resources in Changbai Mountain were investigated.

METHODS:

The chloroplast matK gene and SRAP molecular markers of 94 V. uliginosum samples were analyzed.

RESULTS:

According to the analysis of chloroplast matK gene, all four types were divided into three branches. The results showed low variation among natural samples of V. uliginosum in China and a relationship between haplotype distribution and geographical distribution. The results of the SRAP molecular marker analysis divided the V. uliginosum population into five branches. The multiple individuals of the same trait were clustered together, and different partial samples were clustered together.

CONCLUSIONS:

Diploid alpine V. uliginosum and tetraploid V. uliginosum were identified as two subspecies of V. uliginosum. The elliptical fruit shapewas the variant of tetraploid round blue fruit V. uliginosum, and the white-fruited V. uliginosum variety is a variant.

Background: Duchenne muscular dystrophy (DMD) is a rare, genetic disease caused by mutations in the DMD gene resulting in an absence of functional dystrophin protein. Viltolarsen, an exon 53 skipping therapy, has been shown to increase endogenous dystrophin levels. Herein, long-term (>2 years) functional outcomes in viltolarsen treated patients were compared to a matched historical control group. Objective: To evaluate long-term efficacy and safety of the anti-sense oligonucleotide viltolarsen in the treatment of patients with DMD amenable to exon 53 skipping therapy. Methods: This trial (NCT03167255) is the extension of a previously published 24-week trial in North America (NCT02740972) that examined dystrophin levels, timed function tests compared to a matched historical control group (Cooperative International Neuromuscular Research Group Duchenne Natural History Study, CINRG DNHS), and safety in boys 4 to < 10 years (N = 16) with DMD amenable to exon 53 skipping who were treated with viltolarsen. Both groups were treated with glucocorticoids. All 16 participants elected to enroll in this long-term trial (up to 192 weeks) to continue evaluation of motor function and safety. Results: Time to stand from supine and time to run/walk 10 meters showed stabilization from baseline through week 109 for viltolarsen-treated participants whereas the historical control group showed decline (statistically significant differences for multiple timepoints). Safety was similar to that observed in the previous 24-week trial, which was predominantly mild. There have been no treatment-related serious adverse events and no discontinuations. Conclusions: Based on these results at over 2 years, viltolarsen can be a new treatment option for patients with DMD amenable to exon 53 skipping.

Background: People with Parkinson’s disease (PD) have higher rates of hospitalisation and healthcare utilisation compared to the general population. The COVID-19 pandemic caused significant changes in admissions to hospital and access to healthcare. People with PD are some of the most vulnerable to such changes. There is no pre-existing data on the cause and duration of admission to hospital of people with PD during the COVID-19 pandemic. Objective: To determine the cause, duration, and outcome of hospital admissions to Northumbria Healthcare NHS Foundation Trust (NHCFT) for people with idiopathic Parkinson’s disease (IPD) in 2020. Methods: All people with IPD who had an emergency admission to NHCFT between 01/01/2020 and 31/12/2020 were identified. Demographic and disease characteristics, the number, duration, cause of admission and the location prior to admission were collected from an audit of medical notes. Results: 271 people with IPD had one or more emergency admissions to NHCFT between 01/01/2020 and 31/12/2020. There was a total of 453 emergency admissions, with a median duration of 5 (IQR 2-13) days. The most common causes of admission to hospital were PD-related motor dysfunction (includes falls with no other underlying cause or associated injury) and injury (includes falls with fracture), at 78 (17.2%) and 70 (15.5%) respectively. Conclusions: People with IPD had a short duration but high number of emergency admissions to hospital. Our chronological data on number of admissions shows a peak in admissions during August 2020. As a result of these findings and emerging data we suggest that individuals with PD deconditioned during 2020.

Highlights

• In healthy adults, the lateralized readiness potential (LRP) is localized to the hemisphere contralateral to a moving limb. • In stroke, the LRP can lateralize contra-, or ipsilateral to the paretic limb depending on the stage of recovery. • Identification of hemisphere of recovery can guide further measures for enhancing brain plasticity.

Background:

Event related cortical potentials related to motor action are referred to as movement related cortical potentials. The late component of which is the readiness potential (RP) and its polarity is more negative in the hemisphere responsible for planning of motor action. This lateralized nature of RP during unilateral hand movement is studied as lateralized readiness potential (LRP) by calculating the contralateral-minus-ipsilateral difference wave for each hand.

Objective:

The aim was to identify the hemisphere contributing to motor recovery in acute and chronic stroke patients through recording LRPs.

Methods:

Twenty-nine cases with cerebrovascular stroke (15 acute and 14 chronic) were included in the study. EEG was recorded in response to self-cued button presses by the paretic side to obtain the averaged LRP amplitude. The hemisphere with greater negativity was considered the side of recovery. Functional recovery was assessed by Fugl Meyer test.

Results:

In acute cases, recovery was more related to LRP activity in the contralesional hemisphere (73%), whereas lateralization was equal in chronic cases; 50% in either group. LRP amplitude was higher in the contralesional hemisphere ( p = 0.02). Functional recovery assessed by the Fugl Meyer test (FM) was similar whether recovery was ipsi- or contralesional.

Conclusions:

Early after stroke, motor recovery is more likely to involve compensatory activity in the contralesional hemisphere, while in the chronic phase, the ipsilesional hemisphere may recover its function and become more active. Further research is needed to verify if the technique mentioned in our study could be used to guide customized NIBS protocols tailoring the optimal site and parameters for each patient.

Background and Objectives Obesity is one of the factors associated with metabolic syndrome. The aim of the present study was to compare gross and fine motor skills, insulin resistance and lipid profile in normal, overweight and obese children. Methods In the present study, 120 male and female students were randomly selected by cluster sampling and after final selection, they were divided into three groups of 40 people with normal weight, overweight and obese. The three groups were matched according to their year of birth and body mass index. In order the Bruininks-Oseretsky short form test was used to calculate the motor proficiency score. Biochemical variables were measured while fasting. Statistical analysis, factor analysis of variance and Bonferroni post hoc test were used at a significance level of P≤0.05. Results The results showed that significant decreases in gross and fine motor skills with increasing body mass index (P<0.001). Insulin resistance was significantly higher in obese and overweight groups than normal weight groups (P<0.001). Triglyceride levels were significantly higher in the obese group than the normal weight group (P=0.013). Conclusion According to the results, it can be said that in addition to reducing children's motor skills, increasing body weight causes parameters related to metabolic syndrome in children

At present, with the development of modern technology, the requirements for lubricating oils, especially their viscosity-temperature, thermo-oxidative and lubricating characteristics, are becoming more stringent. In this aspect, the synthesis and study of esters of oxypropylated 2,2,5,5-tetramethylolcyclopentanol (TMCP) with cyclic fragments, active centers, multipolar ester groups is promising, have a certain scientific and practical significance.The esters were synthesized by the esterification reaction of oxypropylated TMCP with aliphatic monocarboxylic acids C4-C8, and their physicochemical, viscosity-temperature, thermal-oxidative and lubricating properties were studied. After determining the viscosity-temperature properties, it was established that they have a low pour point (minus 38-minus 430C), an average viscosity at 1000C (ν100 = 23.50-40.22 mm2/s), a high viscosity index (133-150 units) and flash point (305-3800C). When determining the thermo-oxidative stability of esters, it was found that they have low acid numbers after oxidation (2.51-3.28 mg KOH/g), corrosion of electrodes AK-4 (0.06-0.16 mg/cm2), ШХ -15 (0.08-0.11 mg/cm2) and the precipitate is insoluble in isooctane is low (0.120-0.248% of the mass), the volatility is 0.30-0.50% of the mass. The lubricating properties of esters were also determined: critical load Рк,Н = 750-900, spot wear diameter Di,mm at Р = 196Н = 0.50-0.65. Oxypropylated esters in comparison with reference esters - TMCP ester with caproic acid and pentaerythritol ester (PET) and mixture of fatty acids (MFA) fr. C5-C6 surpass them in almost all parameters, are higher molecular weight and promising, and this makes it possible to create on their basis high-temperature lubricating oils special purpose, components or additives to other lubricating oils.

Published: May 2022

У статті, на основі аналізу діючих кримінально-правової та спеціальної наукової літератури проведено аналіз поняття вік. Біологічний вік дає більш чітке визначення про категорію «вік кримінальної відповідальності», розкриваючи її суть, зміст та основні ключові ознаки. Наукові погляди стосовно визначення віку суб’єктів злочину було розподілено на три групи: перша група - знижений вік кримінальної відповідальності – 11-13 років та загальний вік кримінальної відповідальності – 14 років; друга група – знижений вік кримінальної відповідальності – 14 років та загальний вік кримінальної відповідальності – 16 років; третя група – не має чітко визначеної нижньої межі віку настання кримінальної відповідальності. В КК нижнєю віковою межєю щодо притягнення особи до кримінальної відповідальності є вік з 14 років, загальним віком кримінальної відповідальності є 16 років У виновках та рекомендаціях запропоновано знизити вік осіб, до яких можуть бути застосовані виховні заходи до 10 років. Загальний вік з якого може наставати кримінальна відповідальність знизити до 15 років. Також необхідно здійснити зниження мінімального віку для настання кримінальної відповідальності до 13 років за скоєння суспільно-небезпечних діянь, які наведені в переліку за ч. 2 ст. 22 КК України.
