Increasing Peak Flow of Snyder Synthetic Hydrograph Units in the Serenan Sub-Watershed of Bengawan Solo Watershed
Authors: Barid Burhan , Afanda Brillyana Okta 
Published: September 2022

<p>Changes in land use are closely related to the increasing number of people who are increasing from time to time. This land use change has an impact on increasing the runoff coefficient because the rain that falls will not be retained or seep and flows directly into the river. This is what causes an increase in peak discharge in a watershed. The purpose of this study was to determine the magnitude of changes in peak discharge that occurred in the Serenan watershed in 2015 and 2021 due to changes in land use. The method used in analyzing the peak discharge is the Snyder unit hydrograph, the results of this method will be compared with the measured unit hydrograph to determine the correlation between the two. To make a synthetic unit hydrograph, non-physical parameters are needed in the form of Ct and Cp values. The Ct value used in 2015 was 2.30 and in 2021 it was 2.00 while the Cp value in 2015 was 0.90 and in 2021 it was 1.10. The results of the analysis using the Snyder method showed that the peak discharge was 139.61 m3/s in 2015 and 194.56 m3/s in 2021. The analysis shows that the peak discharge increased by 54.95 m3/s and has a very strong correlation with the hydrograph of the measured unit. </p>
Justifi cation of the use of osteopathic correction in the planned preparation of patients for general anesthesia with tracheal intubation
Authors: Kurnoskin V. L. , Kurbatov O. I. 
Published: September 2022

Introduction. The risk of unsuccessful intubation is a signifi cant problem during elective surgical operations with general anesthesia and tracheal intubation. Taking in consideration the trend towards the development of short-stay surgical hospitals, and the rather low availability of endoscopy services, the search for alternative methods of preparing patients for successful tracheal intubation is in demand. A normal tone of the muscles involved in the work of the temporomandibular joints as well as the tone of the muscles above the hyoid bone and the muscles below the hyoid bone are necessary for successful intubation of the trachea. Based on modern ideas, it can be assumed that an adequate osteopathic effect on the mentioned anatomical structures can provide a decrease in muscle tone. However, there are no publications in the available literature on osteopathic correction of patients at high risk of intubation in order to reduce the risk degree.The aim of the research is to substantiate the use of osteopathic correction in the planned preparation of patients for general anesthesia with tracheal intubation.Materials and methods. The study involved 30 patients with chronic surgical pathology of internal organs who had to undergo elective surgery. The patients were distributed into the control and main groups (15 participants each) by the method of randomization envelopes. The participants of the control group followed the instructions given by the anesthetist, the participants of the main group received additionally a month before the operation two sessions of osteopathic correction with an interval of 14 days. In both groups, the osteopathic status was assessed before the start of the corresponding treatment. The degree of intubation risk and the incision distance were also assessed. After completion of the corresponding treatment, the osteopathic status was re-evaluated in both groups. In the main group, the risk of intubation and the incision distance were re-evaluated.Results. At the beginning of the study, both groups were characterized by a high detection frequency of the following regional biomechanical disorders: neck, thoracic region and dura mater. At the completion of the study, a statistically signifi cant (p<0,05) decrease in the detection frequency of all these disorders was observed in the main group. There was no signifi cant dynamics in the control group. Also in the main group there was a statistically signifi cant (p<0,05) decrease in the intubation risk and an increase in the incision distance value.Conclusion. The obtained results allow recommending the appointment of an osteopath consultation and osteopathic correction during the planned preparation of patients with a high risk of intubation. At the same time, it is recommended to continue the study on a larger sample.

Published: September 2022

Este artículo analizó la existencia de problemas frente a la falta de operatividad cuando se incumplen las decisiones legítimas de autoridad competente en casos de violencia contra las mujeres o miembros del núcleo familiar, teniendo en cuenta derechos indispensables como el debido proceso, la tutela judicial efectiva establecidos en la Constitución de la República. El conjunto de leyes en sentido lato supone la existencia de la obligatoriedad de todos los sujetos de cumplir con lo dispuesto aún si esa norma o decisión no es del agrado del obligado ejecutarla. El respeto a las reglas y decisiones que sean dictadas en un territorio por la autoridad con competencia supone una exigencia de los Estados Constitucionales de derechos. La legislación ecuatoriana ha trascendido en su normativa penal con figuras dirigidas a precautelar la paz social y un efectivo goce de derechos. En la presente investigación se requirió de un análisis e interpretación con bibliografía documental, muestreos y revisión de causas e informes de la Unidad Judicial Especializada de Violencia contra la Mujer y miembros del núcleo familiar de Morona del Consejo de la Judicatura, que, en relación con la LOIPEVM, reflejan porcentajes de causas resueltas, con sentencia y en abandono. Pudiendo así ir identificando el trasfondo de la problemática principal que es la desobediencia de órdenes y a la vez determinar que el proceso para las víctimas necesita acciones efectivas y políticas púbicas que sin perjudicar a las partes procesales superen las debilidades investigativas, sancionatorias y reparativas de derechos.

Published: September 2022

The current study unravels the structural, optical band gap and magnetic characteristics of rare-earth (RE) gadolinium (Gd) substituted CoGdxFe2-xO4 (x= 0.00 - 0.10, in the interval of 0.02) nanocrystallites synthesized by the sol-gel self-ignition route. The XRD analysis and Rietveld refinement confirmed the existence of a single cubic phase with a crystallite size of ~15-21 nm range, further confirmed by HRTEM results. SEM images confirmed the well-known nano-size morphology for all the samples. The magnetization measurements show a hard ferromagnetic nature for all specimens within the temperature range of 20-300K. Coercivity, remanent, and saturation magnetization monotonically increased with a reduction in temperature from 300K to 20K. UV-Vis absorbance results show that the band gap energy of CoFe2O4 nanoparticles (NPs) decreases with increasing Gd3+ ion doping and have band gap energy values of 2.47, 2.15, 2,02, 2.00, 1.43 and 1.95 eV for x= 0.00, 0.02, 0.04, 0.06, 0.08, 0.10, respectively in CoGdxFe2-xO4 nanoferrites. The present study reveals that structural, optical band gap and magnetic properties could be altered by monitoring the quantity of gadolinium in cobalt nanoferrites.

Published: September 2022

Freshwater resources present in the Upper Indus Basin (UIB) supply water to Pakistan’s irrigation. Half of the annual water discharge in the UIB is contributed from the glacier and snow-fed basins in the Hindu Kush, Karakoram, and Himalaya (HKH) region, and it is currently under the threat of climate change. Therefore, it is very necessary to study and monitor the spatiotemporal changes in the snow cover area (SCA) and its response to climate variables to efficiently manage water reservoirs. Thus, keeping this problem in mind, we conducted this study using the Google Earth Engine Application Programming Interface (GEE API) for Astore and Shigar. We used mean annual Landsat data between 1991 and 2021 to derive the SCA using the normalized difference snow index (NDSI). ASTER GDEM data was used to extract the elevation and analyze the distribution of SCA on different elevation zones. Eventually, we used the climate research unit (CRU) data (rainfall and temperature) to analyze them with SCA. The results revealed that SCA in Astore and Shigar has an increasing trend with a rate of 11.16 km2/year and 4.27 km2/year, respectively. Mean annual precipitation and temperature also confirmed the increasing trend of SCA because mean annual precipitation is increasing and temperature is decreasing in both regions. SCA and elevation analysis revealed that SCA is decreasing on foothills while increasing at the valley top. This is because temperature is increasing and precipitation is decreasing from zone 1 to zone 3 and vice versa for zone 4. It is found that Astore and Shigar in UIB have an increasing trend of SCA and are not affected by global warming. Therefore, it is necessary to conduct studies on large scale to efficiently evaluate the impact of climate change on SCA.

Boundaries may have important effects on landscape patterns, landscape change mechanisms, and dynamic processes. However, little is known about the dynamic mechanism of patch boundary changes at a fine scale. To elucidate the characteristics of grassland patches at fine scales and to provide a reference for the mechanism of change and development direction of patchy landscapes. In this paper, the patch of different grassland types in Xilingol League was studied by NMDS, RDA, and SEM methods, to analyze the vegetation community and soil characteristics of surface soil and the relationship between them: The changes in soil vegetation community and soil characteristics were completely different among the three grassland types, and the abrupt changes of vegetation index and soil properties were different. Vegetation index mostly ranged from −1 m to 0 m, and soil index mostly ranged from −0.5 m to 1 m. Fine-scale vegetation and soil boundaries are well defined, vegetation boundaries are mostly between −1 and 0 m and soil boundaries are mostly between −0.5–1 m, and soil properties have a clear influence on plant characteristics. The difference in organic matter, nitrogen, and phosphorus content is an important factor affecting the change of patch boundary, the distribution of the RDA results showed that the organic matter, nitrogen and phosphorus contents in all three grasslands explained &gt;70% of the environmental factors. The emergence of annual vegetation involves a process of succession, specifically, the nature of the underlying soil determines the type of plants at the boundary. The dynamic characteristics of the soil-plant mutual-feed mechanism determine the location and variation of patch boundaries to adapt to disturbance states. The results of this study provide insight into how boundaries respond to changes in environmental conditions and drive dynamic changes at the landscape level.

Published: September 2022

BackgroundWe evaluated the cost-effectiveness of the screening in mainland China for Alzheimer’s disease (AD) patients aged over 60.MethodsIndividuals in mainland China, received an initial screening by questionnaire on mental state, and those with scores deemed suspicious for AD were referred to diagnostic tests. A 9-state Markov model was developed to simulate the disease progression of a cohort of 100,000 subjects aging from 60 to 80. In addition, several scenarios were analyzed to assess the robustness under different screening frequency, starting age, the duration of drug effects, and the health status of subjects.ResultsThe ICER of AD screening was 26413.77 USD per QALY [quality-adjusted life-year (QALY)] compared with no screening. The number of deaths and severe AD cases who did not receive treatment averted by screening accounted for 0.076 and 0.006% of the total population, respectively, and the net monetary benefit was 128.29 USD per capita. Under the thresholds of one and three times the gross domestic product per capita, the probability of screening being cost-effective was approximately 18 and 77%, respectively. The ICER decreased to 18132.96USD per QALY when the drug effect was prolonged, and increased when the frequency of screening was increased, the starting age was postponed, and patients suffering from comorbidities were more. However, the number of severe AD cases and deaths declined when the screening frequency increased.ConclusionScreening for AD in individuals over 60 can reduce the numbers of severe AD cases and deaths and may be cost-effective, depending on factors such as screening frequency, starting age of screening, and duration of drug effects. Additionally, mild cognitive impairment (MCI) is an important stage at which the burden of progression to AD may be reduced and the cost-effectiveness of screening may be improved.
