Published: May 2022

Antimicrobial resistance (AMR) is one of the most significant global health threats. Inappropriate and over-usage of antimicrobial agents (AAs) is a major driver for AMR. Wastewater-based epidemiology (WBE) is a promising tool for monitoring AA usage in communities. Two urban catchment areas have been investigated in this study, one city and one small town in the Southwest of the UK over a 13-month period in 2018-2019. Population normalised loads (PNDLs) of 17 AAs and metabolites have been calculated and compared to catchment specific prescription data. Correction factors (CFs) have been applied to several AAs and metabolites in order to back-calculate consumption at the community level and compare to the corresponding catchment prescription data. Results have demonstrated positive correlations for all quantifiable parent AAs and metabolites in wastewater, and spatial variability in AA usage was observed even in neighbouring urban areas. The application of correction factors demonstrated good agreement for several of the studied AAs, including clarithromycin, oxytetracycline, trimethoprim, hydroxy metronidazole, and acetyl sulfamethoxazole. It was noted that in general, the larger population city gave closer agreement to estimated prescription intake than the smaller town. Differences in wastewater and between prescription data could be due to variable prescribing patterns and potential lack of compliance of AAs at the community level. This study has demonstrated that data triangulation, of both prescription data and wastewater data, provides the most comprehensive approach to understanding AA usage in communities.

Published: May 2022

The spherulitic morphology is considered to be the most common morphology of crystalline materials and is particularly apparent in melt-crystallized products. Yet, historically, the polycrystalline nature of spherulites has hindered successful crystal structure determination. Here, we report for the first time the direct structure determination of a small molecule organic compound in spherulite form using 3D electron diffraction (3D ED). We employed vemurafenib (VMN), a clinical drug used for the treatment of BRAF-mutant melanoma, as a model compound. VMN has four known polymorphs (α-, β-, γ-, and δ-VMN), three of which were discovered by melt crystallization. We first solved the crystal structures of α-, β-, and γ-VMN from both open and compact spherulite samples using 3D ED, and the resulting structures were highly consistent with those solved by single-crystal X-ray diffraction. We then determined the previously unknown crystal structure of δ-VMN—the least stable polymorph which cannot be cultivated as a single crystal—directly from the spherulite sample resulting from spontaneous nucleation. We unexpectedly discovered a new polymorph during our studies, denoted as Form ε. Single crystals of ε-VMN are extremely thin and are not suitable for study by X-ray diffraction. Again, we determined the structure of ε-VMN from both open and compact spherulite forms. This successful structure elucidation of all five VMN polymorphs demonstrates the possibility of removing the time-consuming step of single crystal growth and directly determining structures from spherulite samples. Thereby, this discovery will improve the efficiency and broaden the scope of polymorphism research, especially within the field of melt-crystallization.

Published: May 2022

Objective: Vitamin D deficiency is common in diabetic patients, and studies showed that it could lead to neuropathy. Therefore, we aimed to determine relationship between 25-hydroxyvitamin D (25(OH)D) levels and orthostatic hypotension (OH) which is a component of autonomic neuropathy in diabetic patients.Materials and Methods: A total of 118 patients with Type 2 diabetes mellitus and aged 50-65 years were included. Patients were divided into two groups as OH present and OH not present. 25(OH)D and other variable parameters were evaluated between these two groups.Results: A total of 118 patients, 66 female and 52 male, were included in this cross-sectional study. The mean age of the patients was 56.2±3.2 years. 25(OH)D levels were found to be significantly lower in the group with OH (p<0.026). Age and sex-adjusted regression analysis were performed to examine the relationship between 25(OH)D level and OH. It was found that 25(OH)D didn’t predict the presence of OH in the univariate and multivariate analyses (p >0.05).Conclusion: 25(OH)D levels are significantly lower in diabetic patients with OH. Although an independent relationship between them has not been demonstrated, it can be thought that correcting Vitamin D deficiency will be beneficial in the treatment of OH.

Published: May 2022

Introduction. To study the urbanized territory as a system, an approach was used that allows assessing gaseous and dispersed atmospheric pollution using a unified scale of environmental hazard. The features of air pollution in urban areas were considered, where a significant number of stationary and mobile sources of negative environmental impact are concentrated in limited overpopulated areas.The purpose of the study. the use of theoretical foundations for a systematic assessment of the level of environmental hazard of an urbanized area under the influence of the road network due to a combination of gaseous and dispersed atmospheric pollution.Methods and materials. Based on the improved model of the Urbanized Territory system, the following hypothesis is proposed: 1) motor traffic flows are both independent sources of formation of dispersed particles and sources of uplifting and spreading of particles, which in the presence of gaseous pollutants increases the level of environmental hazard of atmospheric pollution in an urbanized area; 2) atmospheric pollution of an urbanized area is formed when gaseous pollutants and dispersed particles from the street and road network are superimposed on the polluting background of other elements of the Urbanized territory system.Results. The distribution maps of the calculated complex index of atmospheric pollution were obtained for the most problematic areas of the urbanized territory of Naberezhnye Chelny - Prospekt Mira and Kazansky Prospekt. The obtained results characterize the change in the level of environmental hazard of urbanized areas when gaseous pollutants and dispersed particles from the street and road network are superimposed on the polluting background of other elements of the Urbanized territory system.Discussion and conclusion. Based on the generalization and comparison of the results of previous and current studies of the authors, comparing them with the results of other researchers, the hypothesis was fully confirmed. Conclusion. With the confirmation of the hypothesis, the goal of the study was achieved, which has scientific novelty and practical significance for the arrangement of a favorable and comfortable urban environment.

Introduction.Reducing the number of road traffic fatalities and aiming for zero deaths by 2030 is a key road safety government goal. The prevention of especially serious road accidents is one of the elements of achieving this goal. Analysis of the main factors contributing to the especially serious road accidents occurrence is the basis of an effective system for their prevention. A review of the scientific literature reveals a lack of knowledge in this area.

Materials and methods.The study was performed on the basis of especially serious road accidents sample. The accidents that occurred in the regions of the Siberian Federal District in the period from 2017 to 2020 were analyzed. The following parameters were analyzed: the number of dead and injured, the type of accident, the period of the day, the day of the week, the month of the year, the weather conditions and the condition of roadway. The study is based on a multidimensional frequency distribution. The calculations and graphs were made using MS Excel and Statistica.

Results.The results are presented using 2D and 3D histograms and cross tables. An analysis of the especially serious road accidents structure made it possible to distinguish two groups of accidents that differ in the number of the injured and dead. The influence of the analysed factors contributing to the especially serious road accidents occurrence is determined.

Practical importance.Knowledge of the factors influence on the frequency of especially serious road accidents occurrence will allow public services to effectively plan measures to prevent such accidents and respond to them. This will reduce the number of road accidents deaths.

Originality.Two groups of road accidents with especially serious consequences are identified and substantiated. It was found that the factors have different effects on the distribution of accidents in these groups. The study contains new knowledge of the factors contributing to the especially serious road accidents occurrence.

Published: May 2022

Introduction. The purpose of the article is to consider the effect of damping in the shock absorber on smooth running, continuous rolling of the wheel and energy loss in the suspension of the car.

Materials and methods. The review is based on the analysis of the amplitude-frequency characteristics of a two-mass car model and the dependence of the shock absorber operation during the oscillation cycle on the frequency of kinematic action.

Results. The article presents a calculation scheme and equations of dynamics of a two-mass oscillatory system equivalent to an automobile suspension. The frequencies at which the amplitude-frequency characteristics intersect for different levels of damping (invariant points) in a two-mass oscillatory system are calculated. The relative operation of the shock absorber for the oscillation cycle concept is proposed and a formula for calculating the relative operation of the shock absorber in a two-mass oscillatory system is given. A comparative analysis of graphs characterizing smooth running, continuous rolling of the wheel and energy losses in the suspension is carried out.

Discussion and conclusions. It is revealed that significant contradictions between these requirements arise only near the second resonance of the sprung mass, with an increase in the frequency of vibrations in the resonant zone, these contradictions are decrease.

Authors: Yakunin I. N. , Fot A. P. , Yakunin N. N. , Fattakhova A. F.
Published: May 2022

Introduction. The accident rate in road transport in the summer period of the year in conditions of high ambient temperatures has a steady upward trend. The main reasons for this situation are changes in the condition of drivers and the low efficiency of the climate systems of some vehicles. Motor transport enterprises take into account the conditions of the external environment in their activities and adjust the technology of the transport process. Such environmental conditions are ice, fog, precipitation, low air temperature and others. However, high ambient temperature is not included in such a list. In this regard, the study of the features of the functioning of a motor transport enterprise in conditions of high ambient temperatures and the development on this basis of a functional model for ensuring road safety is an urgent task.

The purpose of this work is to improve the safety of road transport on the basis of the development of a functional structure of the road safety service of a motor transport enterprise, taking into account the high ambient temperature.

Methods. The work is based on the synthesis of general scientific research methods, which included the provisions of system analysis, as well as the provisions of the theory of transport processes, the technical operation of vehicles.

Results. The result of the work was the developed functional model of the road safety service of a motor transport enterprise, according to which the road safety service is endowed with control and administrative functions in relation to the activities of the personnel service, technical service and operation service on issues related to road safety. This model differs from the known ones in that it contains functions for responding to high ambient temperatures. An algorithm has been developed for the functioning of the traffic safety service in conditions of high ambient temperature, which prevents its influence on the increase in the aggressiveness of driving cars and the low efficiency of the climate systems of a part of vehicles. These provisions constitute the scientific novelty of the work.

Discussion and conclusion. The practical value of the work lies in the improvement of the tools of the motor transport enterprise, aimed at preventing an increase in the accident rate in conditions of high ambient temperatures.

Published: May 2022

Objetivo.

Descrever a distribuição espacial da comorbidade tuberculose-diabetes e identificar os determinantes sociais da dupla carga no período de 2012 a 2018 no Brasil.

Métodos.

Este estudo ecológico utilizou os municípios como unidade de análise. Incluíram-se todos os casos de tuberculose notificados de 2012 a 2018 ao Sistema de Informação de Agravos de Notificação. Como determinantes, foram analisadas variáveis socioeconômicas de emprego, renda e desenvolvimento e o indicador de cobertura da atenção básica. O índice de Moran global foi calculado para verificar a existência de autocorrelação espacial da comorbidade. O índice de Moran local foi utilizado para delimitar clusters de tuberculose-diabetes: alto/alto (municípios com alta proporção de tuberculose-diabetes cujos vizinhos também apresentaram altas proporções) e baixo/baixo (municípios com proporção abaixo da média, cercados por municípios com baixas proporções).

Resultados.

Observou-se elevação na proporção de tuberculose-diabetes na maioria das regiões brasileiras. Constatou-se autocorrelação espacial da comorbidade tuberculose-diabetes e identificou-se um cluster alto-alto de tuberculose-diabetes reunindo 88 municípios, pertencentes principalmente às regiões Nordeste, Sudeste e Sul, com média de prevalência da comorbidade de 28,04%. As variáveis “percentual da população que vive em domicílios com densidade superior a duas pessoas por dormitório”, “percentual de desemprego de pessoas maiores de 18 anos” e “renda per capita” relacionaram-se à ocorrência da comorbidade.

Conclusão.

Os resultados mostraram uma distribuição não aleatória da comorbidade tuberculose-diabetes, com áreas de alto risco e variáveis explicativas de sua ocorrência. Esses achado reforçam a necessidade de operacionalizar a colaboração entre programas de tuberculose e diabetes, com vistas ao controle tanto de cada agravo isoladamente quanto da sindemia.

Purpose: There are numerous advantages to train the swimmers on swim-bench, which is why this systematic review critically evaluate the published data for this practise. The current review’s purpose is to evaluate the efficacy of swim bench training in light of recent research conducted over the past five years.
Methodology / Evidence Acquisitionː Published articles that examined the benefits and uses of a swim bench training on an athlete were reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An electronic database search based on three databases that include PubMed, Google Scholar, and Taylor & Francis was done using keywords "Swim bench” and “Swim bench training”. The database search was limited to articles between January 2016 to the date to include the data of 5 years. It retrieved 1289 articles on sight. Articles that were originally published in a language other than English or did not have translated version in English were omitted from the study by the researcher. Conclusionsː Jaime & Maria (2017) and González Ravé J et al., (2018) studied isokinetic force production, there was no significant result found related to isokinetic force and in isokinetic power a slight decrease was observed in that of isokinetic force. Whereas, Popovici & Suciu (2017) proved the strength and velocity gain in young female swimmers after swim bench training and also enhanced muscle synchronization as well as improved propulsive force generation and considered it as a source of improvement and immediate instruction for better training purposes. However, swim-bench is widely being used from coaches in several manner of dry land training among swimmers at elite level as well. it is further suggested that further experimental studies needed to observe the swim-bench effect on training as well as rehabilitation purpose scientifically with the principal of specificity of sports training.

Published: May 2022

Los Modelos de Elevación Digital (MED) constituyen uno de los insumos más importantes para realizar análisis mediante Sistemas de Información Geográfica. El MED mexicano oficial es el CEM 3.0 de INEGI. Uribe-Alcántara et al. [1] realizaron una evaluación del CEM 3.0 en tres zonas con distintas características topográficas: 1) una zona agreste (pendientes y elevaciones altas), 2) una zona de transición (pendientes y elevaciones medias), y 3) una planicie (pendientes suaves y elevaciones bajas). Se encontró que la zona con los errores más altos correspondía a la planicie de inundación, donde, aunque las elevaciones son menores a 10m, los errores pueden alcanzar cientos de metros, es decir, los errores alcanzan valores inverosímiles de más del 1000%. El presente artículo explora en detalle las causas e implicaciones de esos errores mediante mapas de errores, secciones transversales, así como de modelos tri-dimensionales y su relación con cuerpos de agua. El análisis sugiere que los errores se deben a una manipulación de las elevaciones en la vecindad de cuerpos de agua menores realizada por INEGI, que consiste en crear murallas artificiales de hasta cientos de metros alrededor de ellos. Dicha manipulación constituye una seria limitante para la aplicación del CEM 3.0, especialmente en estudios hidrológicos, donde la exactitud de la red de flujo es muy importante, especialmente para la identificación de planicies de inundación.
Evaluación de una metodología de coagulación: ácido húmico-arsénico en presencia de Fe3+ por potencial zeta
Authors: Nieto-Velázquez S. , Torres Ortiz D. , Páez-Hernández M. E.
Published: May 2022

En la materia orgánica del suelo (MOS) encontramos a los ácidos húmicos (AHs), son polímeros naturales altamente reactivos con gran complejidad estructural y variabilidad. Debido a su polifuncionalidad presentan interesantes y útiles propiedades físicas, químicas y biológicas, lo cual ha hecho atractivo su estudio desde hace más de 200 años. Sin embargo, su origen y estructura aún no han sido esclarecidos totalmente, por lo cual, continúa el interés por conocer y describir más precisa y detalladamente sus propiedades termodinámicas y fisicoquímicas. Es por todo lo anteriormente expuesto, que en este trabajo de investigación se plantea el estudio sistemático y formal de una metodología de coagulación de los AHs (comercial y extraído en el laboratorio) con una concentración de 50 mg/L, con 0.5 y 1.0 mg/L de As y con diferentes concentraciones de la sal de Fe3+ (1, 2 y 3 mM) e intervalos de pH (5 y 7), mediante potencial zeta. Con estas condiciones se evidenció que existe una rápida interacción de los AHs con Fe3+, incrementando la coagulación al aumentar la concentración del metal y a un pH mayor de 4, debido a la desprotonación de los grupos carboxílicos (-COOH) principalmente, que bajo estas condiciones pueden coordinarse, reduciendo la carga neta negativa y permitiendo así que tales complejos se aproximen entre sí e interactúen a través de puentes de hidrógeno. Todo con la finalidad de contribuir a la comprensión de los mecanismos de movilidad de iones en sistemas ambientales.

La técnica de difracción de rayos X (DRX) confirmó la matriz de la muestra mineral correspondiente a un sulfuro de plomo (PbS [COD 96-901-3404]) y la presencia de otras especies minerales como esfalerita (ZnS [COD 96-110-1051]), calcopirita (CuFeS2 [COD 96-901-5235]) y Lenaita (AgFeS2 [COD 96-900-4980]) donde se identificó el contenido de plata. Por otro lado, la técnica de microscopia óptica de polarización (MOP) permitió corroborar la matriz del concentrado, además de la presencia de especies minoritarias como pirita (FeS2), calcopirita (CuFeS2), arsenopirita (FeAsS) y esfalerita (ZnS). Mediante microscopia electrónica de barrido-análisis de energía dispersivas (MEB-EDS) se obtuvo el análisis semicuantitativo de los elementos Pb, Al, As, Cu, Fe, S y Si, así como la relación elemental de los contenidos metálicos mediante el mapeo realizado a la muestra mineral. La morfología irregular de las partículas del concentrado fue confirmada por micrografías obtenidas mediante electrones secundarios y retrodispersados. Finalmente, se muestran los resultados obtenidos de la propuesta de lixiviación, en donde la mayor recuperación de plata se obtiene en el sistema S2O3-2-O2-Zn2+.

Non-Cash Food Assistance (BPNT) aims to reduce the burden of public spending in meeting basic needs. However, there are some problems with distribution. This research focuses on indicators of the effectiveness of the distribution of the BPNT assistance program, namely target accuracy, choice accuracy, and timeliness, as well as the benefits of the BPNT program for the community. This study uses a qualitative approach with a descriptive method. The types of data used are primary and secondary data. Data collection techniques through observation, interviews and documentation. The results of the study illustrate that the effectiveness of the distribution of non-cash food assistance in Bireuen Regency has not been fully running well because BPNT recipients are not on target. Meanwhile, KPM is not given the freedom to choose aid materials according to their needs, so it is not the right choice. In addition, the schedule for assisting is still not following the provisions so that it is not on time. The benefits of the program can be directly felt by the poor in improving food security and improving the economy for SMEs (e-Warung). Overall, the distribution of Non-Cash Food Assistance (BPNT) to KPM is still less effective. ABSTRAKBantuan Pangan Non Tunai (BPNT) bertujuan mengurangi beban pengeluaran masyarakat dalam pemenuhan kebutuhan pokok. Namun dalam penyaluran terdapat beberapa permasalahan.  Penelitan ini berfokus pada indikator efektivitas penyaluran program bantuan BPNT yaitu ketepatan sasaran, ketepatan pilihan, dan ketepatan waktu, serta manfaat program BPNT bagi masyarakat. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif. Jenis data yang digunakan adalah data primer dan sekunder. Teknik pengumpulan data melalui observasi, wawancara dan dokumentasi. Hasil penelitian menggambarkan bahwa efektivitas penyaluran bantuan pangan non tunai di Kabupaten Bireuen belum sepenuhnya berjalan dengan baik karena penerima BPNT tidak tepat sasaran. Sementara KPM tidak diberikan kebebasan dalam pemilihan bahan bantuan sesuai dengan kebutuhan sehingga tidak tepat pilihan. Selain itu, jadwal pemberian bantuan masih belum sesuai dengan ketentuan sehingga tidak tepat waktu. Adapun manfaat program langsung dapat dirasakan oleh masyarakat kurang mampu dalam meningkatkan ketahanan pangan dan meningkatkan ekonomi bagi pelaku UKM (e-Warung).  Secara keseluruhan penyaluran Bantuan Pangan Non Tunai (BPNT) kepada KPM masih kurang efektif.

Para pengrajin tepas bambu di Gampong Buket Teukuh Kabupaten Bireuen masih menjalan roda usaha mereka secara tradisional. Praktis tidak banyak inovasi yang dilahirkan dari kerajinan tepas bambu, sedangkan modal usaha yang dimiliki sangat terbatas. Minimnya program-program pemberdayaan yang diinisiasi oleh pemerintah daerah dan pemerintah desa terhadap para pengrajin membuat usaha ini jalan di tempat. Penelitian kualitatif ini menggambarkan bahwa selama ini para pengrajin tepas bambu di Gampong Buket Teukuh memiliki strategi dalam mempertahankan keberlangsungan usaha mereka walau minim dukungan pemerintah. Realitasnya mereka membangun hubungan yang saling menguntungkan dengan para agen. Keberadaan agen membantu para pengrajin mendapatkan modal dalam membeli bahan baku tepas bambu yang dibutuhkan serta memasarkan produk-produk yang dihasilkan ke pasar-pasar pekan di wilayah pantai timur Aceh. Modal sosial ini sudah terjalin lama, bersifat resiprokal, dan dibangun atas dasar rasa saling percaya.

This study discusses the procedure for determining the dowry in the Acehnese marriage tradition. Then the influence of social status on the value of the dowry for women in Mamplam Village, Nibong District, North Aceh Regency. We have used a qualitative approach in this study. Some data was collected by interview techniques. Analysis techniques use data reduction, data presentation, and draw conclusions or verification. The results showed that the procedure for determining the dowry in Gampong Mamplam was carried out by an application process mediated by Seulangke. Seulangke serves as a liaison between the groom and the bride. If the application from a man is accepted by the woman and her family, then after a while the process is followed up to the delivery of a dowry for the woman from the family of the man who is applying. The dowry in marriage is determined by the parents of the woman or based on the results of family deliberation. Then the value of the dowry is also strongly influenced by social status, namely the level of education and the level of wealth. If the woman comes from a rich family then the amount of dowry is quite high, it can reach the value of 20-25 mayam gold. Meanwhile, for women who come from simple families, the amount of dowry is relatively less, only around 10-15 mayam gold.
