Published: July 2021

Land use change is an important driving force factor affecting the river water environment and directly affecting water quality. To analyze the impact of land use change on water quality change, this study first analyzed the land use change index of the study area. Then, the study area was divided into three subzones based on surface runoff. The relationship between the characteristics of land use change and the water quality grade was obtained by grey correlation analysis. The results showed that the land use types changed significantly in the study area since 2000, and water body and forest land were the two land types with the most significant changes. The transfer rate is cultivated field > forest land > construction land > grassland > unused land > water body. The entropy value of land use information is represented as Area I > Area III > Area II. The shift range of gravity center is forest land > grassland > water body > unused land > construction land > cultivated field. There is a strong correlation between land use change index and water quality, which can be improved and managed by changing the land use type. It is necessary to establish ecological protection areas or functional areas in Area I, artificial lawns or plantations shall be built in the river around the water body to intercept pollutants from non-point source pollution in Area II, and scientific and rational farming in the lower reaches of rivers can reduce non-point source pollution caused by farming.

Published: July 2021

Rapid urbanization influences the landscape pattern of impervious surfaces, and potentially affects surface water quality. Using ArcGIS and Fragstats, this study analyzed the temporal change of the landscape pattern of impervious surfaces in Shanghai over the past 45 years, and its driving forces and impact on water quality were also analyzed. The results show that both low and high impervious surfaces showed different degrees of expansion, and as a result, the pervious surfaces and water area reduced by 40.1% and 13.8%, respectively. It proves that the fragmentation and diversity of impervious surfaces in Shanghai notably increased in the past decades, and especially the low and high impervious surfaces show substantial changes. The primary driving forces of the landscape pattern change are population density, unit area Gross Domestic Product (GDP), and the percentage of primary industry. The result of Redundancy analysis (RDA) is that the explanatory ability of landscape pattern to water quality variations decreased from 68.7% to 46.4% in the period 2000–2010. It should be stressed that the contribution of the configuration of impervious surfaces to water quality variation is less than that of the percentage of impervious surfaces.
Relationships between Leaf Area Index and Evapotranspiration and Crop Coefficient of Hilly Apple Orchard in the Loess Plateau
Authors: Jia Qiong , Wang Yan-Ping
Published: July 2021

Drought and water shortage are the key factors that restrict the sustainable development of the apple industry in the Chinese Loess Plateau. The accurate prediction of ET can provide a scientific basis for water management of apple orchards. A study on the relationship between LAI, ET and crop coefficient Kc under water deficit is particularly necessary for the accurate prediction of ET in apple orchards. In this work, the crop coefficient Kc under water deficit was defined as the product of the crop coefficient KcI under no water stress and the water stress coefficient Ks, namely Kc = KcI × Ks. LAI and ET of the hilly apple orchard were measured from April to September in 2019 and 2020. The results showed: (1) The LAI of the apple orchard showed a trend of rapid increase—moderate increase—declined during the growth period, with 0.26–2.16 [m2 m−2] variation range; (2) The ET of the orchard was greater than the rainfall, the maximum ET was in July or August. The maximum components of ET in the apple orchard was E, with 47.8–49.1% of ET; T accounted for 42.5–43.9% of ET; Ic accounted for only 9.1–9.6% of ET; (3) There was a significant exponential relationship between the LAI and T or ET. The crop coefficient KcI under no water stress changed with the development of the apple tree canopy. The variation of water stress Ks was basically consistent with the variation of rainfall; (4) There is a significant exponential relationship between LAI and crop coefficient Kc under water deficit (Kc = 0.1141e1.0665LAI, R2 = 0.7055, p < 0.01). This study demonstrates that LAI could be used to estimate the crop coefficient Kc of apple orchards under water deficit in the Loess Plateau, and the actual evapotranspiration of apple orchards in this region could be predicted.

Authors: Wang Hsing-Yu , Fang Hui-Ming , Chiang Yun-Chih
Published: July 2021

In this study, a hydrodynamic model was used that includes the effects of wave–current interactions to simulate the wave and current patterns before and after offshore wind turbine installation in western Taiwan. By simulating the waves and currents after the offshore wind turbine was established, the waves and currents caused by the wind turbine were seen to have a limited range of influence, which is probably within an area about four to five times the size of the diameter (12–15 m) of the foundation structure. Overall, the analysis of the simulation results of the wave and current patterns after the offshore wind turbines were established shows that the underwater foundation only affected the local area near the pile structure. The wind farm (code E) of the research case can be equipped with about 720 cage cultures; if this is extended to other wind farms in the western sea area, it should be possible to produce economic-scale farming operations such as offshore wind power and fisheries. However, this study did not consider the future operation of the entire offshore wind farm. If the operation and maintenance of offshore wind farms are not affected, and if the consent of the developer is obtained, it should be possible to use this method to provide economically large-scale farming areas as a mutually beneficial method for offshore wind power generation and fisheries.

In this study, activated carbon (AC) and magnetic activated carbon (MAC) were prepared from Dalbergia sissoo sawdust for the removal of antibiotic Azithromycin (AZM) from aqueous solution. The effect of initial concentration, contact time, pH, adsorbent dosage, and the temperature were investigated for both the adsorbents. The optimum AZM concentration, contact time, pH and adsorbents dosages were found to be 80 mg/L, 120 min, 6 and 7 (pH, respectively, for AC and MAC), and 0.1 g (for both AC and MAC), respectively. The isothermal data of both sets of experiments correlated well with the Langmuir isotherm model, while the kinetic data with the pseudo-second-order model. The adsorption of AZM on both adsorbents was found to be favorable, which is evident in the values of the thermodynamic parameters (ΔH = −26.506 and −24.149 KJ/mol, ΔS = 91.812 and 81.991 J/mol K, respectively, for AC and MAC). To evaluate the effect of AC and MAC on the membrane parameters, a continuous stirred reactor was connected with ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes. High % retention and improved permeate flux (around 90%) were obtained for AC/UF, AC/NF AC/RO, MAC/UF, MAC/NF, and MAC/RO treatments. The percent retention of AZM observed for AC/UF, AC/NF AC/RO was higher than MAC/UF, MAC/NF, and for MAC/RO hybrid processes due to greater surface area of AC than MAC.

The influence of the characteristics of polyethylene on thermoelectric properties of their composites with black carbon
Authors: Markov A. V. , Markov V. A. , Chizhov A. S.
Published: July 2021

The work is devoted to the study of the effect of characteristics (melt flow and density) of various grades of polyethylene on the electrical resistance of polyethylene composites with carbon black at normal and elevated temperatures. Such polyethylene composites are characterized by abnormally high values of the positive temperature coefficient of electrical resistance in the melting temperature range of the polyethylene matrix. This causes the effect of power self-regulation of such heaters (selfregulating polymer heaters). It has been established that the content of carbon black, which provides a stable and clear effect of self-regulation of such heaters, is located in a concentration region approaching the region of the second concentration-structural percolation transition, which for all investigated polyethylene composites was about 12 vol% of carbon black. The growth rate of electrical resistance at these carbon-black contents is influenced by crystallinity of the polyethylene matrix.

Todo ser humano, donde se encuentre, siempre está inmerso y en relación dinámica con la cultura que lo rodea, sean personas diversas, o universitarios, entonces la misión de la docencia es formar personas conscientes de su mundo y de lo que son capaces de hacer a favor de este. Este ensayo permitió dilucidar sobre la cultura de vida vinculada a la docencia de enfermería, concluyendo que la desestructuración del proceso pedagógico de enfermería sin cultura de vida, resta el espíritu de superación de estudiantes con expectativas de progreso, porque se considera a veces a la ignorancia como la única e inequívoca expresión de dominio.

En la docencia de enfermería, considerando la característica humana que identifica su labor, asociando cultura de la vida y los enlaces figurativos que no se evidencian en la formación, evoca sensaciones extrañas, que difícilmente se pueden explicar con palabras, ante la contemplación de tantas desigualdades.
Comunicación entre padres e hijos adolescentes sobre conductas de riesgo a la salud
Authors: Alvarez Aguirre Alicia , Hernández Rodríguez Verónica Margarita
Published: July 2021

Hoy día el adolescente vive sus relaciones interpersonales mediadas por las redes sociales y conducidas socialmente hacia la toma de conductas de riesgo, motivadas desde el poder y la aceptación por su entorno de pares. Esta circunstancia pone en relieve la importancia que tienen los padres, como esas personas significativas que habrán de introyectar en el adolescente valores y conductas que impulsen su desarrollo biopsicosocial. De ahí que, la comunicación entre padres e hijos es pieza clave y fundamental, ya que el diálogo asertivo y afectivo facilitará el intercambio de experiencias que serán de utilidad al adolescente al momento de tomar decisiones. El detalle ante esto, es que evidencias académicas y científicas apuntan a que dicha comunicación no se lleva a cabo, dejando al adolescente desprovisto de elementos que contribuirían a su crecimiento y desarrollo personal. Por lo que en el siguiente ensayo se despliega una reflexión sobre la comunicación entre padres e hijos adolescentes respecto a las conductas de riesgo a la salud.

Accurate prediction of bonding properties by a machine learning–based model using isolated states before bonding
Authors: Suzuki Eiki , Shibata Kiyou , Mizoguchi Teruyasu
Published: July 2021

Bonding characters, such as length and strength, are of key importance for material structure and properties. Here, a machine learning (ML) model is used to predict the bonding properties from information pertaining to isolated systems before bonding. This model employs the density of states (DOS) before bond formation as the ML descriptor and accurately predicts the binding energy, bond distance, covalent electron amount, and Fermi energy even when only 20% of the whole dataset is used for training. The results show that the DOS of isolated systems before bonding is a powerful descriptor for the prediction of bonding and adsorption properties.

Published: July 2021

We fabricated an ionic-liquid conductive-bridge memory (IL-CBRAM) in which the solid-state electrolyte in a conventional CBRAM sandwich structure of Cu- and Pt-electrodes was replaced with IL. To stabilize the Cu-filaments in IL, an additional metal layer with a standard electrode potential (SEP) lower than that of Cu was inserted into the memory cell. We found Ta to be promising for this purpose, because the SEP in IL exhibited the Ta < Cu < Pt relation. Actually, inserting the Ta-adhesion layer increased the data-retention time. The data-retention characteristics control through cell design considering the SEP arrangement of metals was successfully demonstrated.

The maritime sector is one of the paths to Golden Indonesia 2045. This is because 70% of Indonesia's territory is a sea with an area of ​​3.25 million km2 and is supported by the large potential that can be utilized for the welfare of Indonesia, one of which is as a contributor to foreign exchange with foreign exchange potential from maritime sector amounting to US $28 million to US $56 million. The problem lingers on how to possible solve the problem regarding air pollution without shutting down industrial operations. Many multinational power plants have launched different campaigns in order to minimize the problem like planting trees and the like. But these small growing industries like grilling restaurants have given way to arising problem of air pollution issues On the other hand, the ocean is a contributor to half of the world's oxygen. But in a period of 50 years, areas with minimal oxygen levels in the oceans have increased. The main cause is global warming, one of which comes from increasing levels of carbon monoxide in the air. One of these gases comes from incomplete combustion in motorized vehicles. This is also exacerbated by the growth of motorized vehicles which has increased by 11.5% per year. If left like this, marine life will be destroyed and Indonesia will not reach its peak of glory in 2045. So to overcome this problem, a prototype design of Carbon Monoxide Box Separator was created. This prototype is a combination of detector sensors consisting of MQ7 to detect carbon monoxide, MQ135 to measure air quality, and DHT11 to measure humidity and air temperature, as well as a high voltage system on the L-Box (Lightning Box) which can produce O2 because of the copper plate. on the L-Box will bind the element carbon to carbon monoxide using a voltage of 400 kV. With this prototype design, it is hoped that Indonesia can achieve its glory and also as a form of QS practice. Ar-Rum verse 41 regarding Allah's command to preserve nature and the environment.

Published: July 2021

Monitoring the baby's health status is very important, especially for babies born prematurely. Oxygen saturation levels in newborns are very important to know because when the oxygen saturation levels in newborns are low, it is necessary to watch out for hemodynamic abnormalities in the baby. Measurement of oxygen saturation levels in newborns can help detect congenital abnormalities in infants early. This study aims to design an equipment system to continuously monitor the condition of oxygen saturation in newborns. Where in this discussion a monitoring tool is used to monitor 2 premature babies in a baby incubator simultaneously using a Neonatal Fingertip sensor. The system will display the oxygen saturation (SpO2) value and signal. Monitoring on this tool is done wirelessly using the HC-05. Based on the results of tests and measurements in 5 different patients with a pulse oximeter comparison, the difference value of 1% in each patient's results was obtained. The results of this study will greatly help facilitate the work of paramedics in monitoring the vital conditions of newborn babies.

To investigate the diagnostic accuracy of deep learning (DL) algorithms to detect primary open-angle glaucoma (POAG) trained on fundus photographs from the Ocular Hypertension Treatment Study (OHTS). 66,715 photographs from 3,272 eyes were used to train and test a ResNet-50 model to detect the OHTS Endpoint Committee POAG determination based on optic disc (n=287 eyes, 3,502 photographs) and/or visual field (n=198 eyes, 2,300 visual fields) changes. OHTS training, validation and testing sets were randomly determined using an 85-5-10 percentage split by subject. Three independent test sets were used to estimate the generalizability of the model: UCSD Diagnostic Innovations in Glaucoma Study (DIGS, USA), ACRIMA (Spain) and Large-scale Attention-based Glaucoma (LAG, China). The DL model achieved an AUROC (95% CI) of 0.88 (0.82, 0.92) for the overall OHTS POAG endpoint. For the OHTS endpoints based on optic disc changes or visual field changes, AUROCs were 0.91 (0.88, 0.94) and 0.86 (0.76, 0.93), respectively. False-positive rates (at 90% specificity) were higher in photographs of eyes that later developed POAG by disc or visual field (19.1%) compared to eyes that did not develop POAG (7.3%) during their OHTS follow-up. The diagnostic accuracy of the DL model developed on the OHTS optic disc endpoint applied to 3 independent datasets was lower with AUROC ranging from 0.74 to 0.79. High diagnostic accuracy of the current model suggests that DL can be used to automate the determination of POAG for clinical trials and management. In addition, the higher false-positive rate in early photographs of eyes that later developed POAG suggests that DL models detected POAG in some eyes earlier than the OHTS Endpoint Committee.

Comprehensive Safety Evaluation of Highly Automated Vehicles at the Roundabout Scenario
Authors: Wang Xinpeng , Zhang Songan , Peng Huei
Published: July 2021

A highly automated vehicle (HAV) is a safety-critical
system. Therefore, a verification and validation (V&V) process
that rigorously evaluates the safety of HAVs is necessary before
their release to the market. In this paper, we propose an
interaction-aware safety evaluation framework for the HAV and
apply it to the roundabout entering, a highly interactive driving
scenario with various traffic situations. Instead of assuming
that the primary other vehicles (POVs) take predetermined
maneuvers, we model the POVs as game-theoretic agents. To
capture a wide variety of interactions between the POVs and
the vehicle under test (VUT), we use level-k game theory and
social value orientation to characterize the interactive behaviors
and train a diverse library of POVs using reinforcement learning.
The game-theoretic library, together with initial conditions, form
a rich testing space for the two-POV roundabout scenario. On
the other hand, we propose an adaptive test case generation
scheme based on adaptive sampling and stochastic optimization
to efficiently generate customized challenging cases for the VUT
from the testing space. In simulations, the proposed testing space
design captured a wide range of interactive situations at the
roundabout scenario. The proposed test case generation scheme
was found to cover the failure modes of the VUT more effectively
compared to other test case generation approaches.
The Dubious Authority of Maxwell’s Equations in Free Space

Discussion of the draft of the new criminal code of Ukraine revealed conceptual shortcomings in it. Some of them are the legacy of the past. Others, however, are born of blind imitation of Western models. In defining the basic concepts of the criminal code, it is necessary to take into account changes in the balance of public and private principles, the interests of the individual and the state. Ukraine should adopt a criminal code that fully takes into account its national identity and current needs for protection from the most serious criminal threats.

Authors: Rep'ev Artem , Repeva Anna
Published: July 2021

The authors analyze the current trends in the legislative process of the Russian Federation, one of which is the specification of law. It is hypothesized that, through the specification of legal regulations, a specialization of legislation is formed, among the most common forms of which in the framework of criminal enforcement law are: differentiation, individualization and specificity. On the basis of an analysis of legal doctrine, legislation and law enforcement practice, the authors conclude that the objectives of the specification of prison law include: the specificity of the elements of the legal situation of the convicted person, the addition of conditions and forms of correction, and the consolidation of additional measures to stimulate law-abiding behavior. Problems have been identified in the implementation of specific norms of criminal enforcement law, which slow down the process of reforming the system of execution of punishment, and ways have been proposed to solve them.

Review on Common Infectious Diseases of Neonatal Calves
Authors: Galma Boneya Arero
Published: July 2021

Neonatal calf mortality is one of the important problems of calf rearing in dairy farms worldwide. A successful dairy farm operation requires that a large percentage of cows wean a live healthy calf every year. However, in many developing countries, a large number of calves die during the early neonatal life, this causing heavy economic loss. This is due to several infectious (bacterial, viral, and protozoal) and non-infectious factors (management around birth, colostrum management, calf housing, feeding system, hygiene, and pathogens) play an important role in calf rearing. This paper aims to review major infectious causes of neonatal calf mortality. Numerous studies have been conducted in the past from many parts of the world using both retrospective and prospective data sources to document the major causes of calf mortality. Of the infectious diseases of calves, neonatal diarrhea is a matter of major concern, and multiple etiological agents from viruses (Bovine rotavirus, Bovine coronavirus, Bovine viral diarrhea virus) from bacteria (Salmonella spp, Escherichia-coli, and Clostridium perfringens) from protozoal (Cryptosporidium-parvum) have been identified as major causes of neonatal calf mortality. Among the infectious agents, rotavirus and E. coli are mainly involved in the causation of neonatal calf diarrhea which leads to high mortality and morbidity in young calves. E. coli mainly plays its role up to the second week of life whereas, rotavirus up to the third week. Generally, early calf mortality leading to economic losses due to the cost of treatment, prophylaxis, increased susceptibility to other infections, reduced growth rates, and death of calves.
