Application of traditional cultural elements in landscape design
Authors: Liu Tong
Published: June 2023

Traditional Chinese cultural elements have diversified the framework of contemporary cultural studies and given new life to modern landscape design. Therefore, the use of traditional Chinese cultural elements in modern landscape design is the main task faced by landscape design designers. This paper establishes the SVM-design model. An in-depth study on the use of traditional cultural elements in landscape design is launched. The calculation analysis shows that the color application of traditional cultural elements is the most widely used in the creation of landscape space, and its percentage is as high as 60.22%. The use of regional characteristics of traditional cultural elements accounted for the second highest percentage, at 24.73%. The lowest percentage of pattern features of traditional cultural elements is used in the creation of landscape space, only 15.05%. The percentage of the use of traditional cultural elements of the deformation of the exaggerated clothing method is 43%. The reason for its wide application in landscape design is that it is a deformation and exaggeration treatment of the external form of traditional cultural elements to achieve the aesthetic effect of highlighting and amplifying the traditional cultural elements.

To strengthen networks’ security performance, here pose suggests a fused full convolutional approach to monitoring computer networks. This paper first analyzes the various performances of the full convolutional model for error problems rate, error reporting, and monitoring effects on various attack categories then proposes a network monitoring scheme for the full convolutional model and introduces the workflow of the full convolutional model in computer network security protection. In terms of accuracy, the full convolutional error rate of the blueprint meets the requirements rate of 96.8%, which is better than the classical network models of Lenet-5 and AlexNet, with 86.2% and 91.6%. The false alarm rate is only 2.37%, which is lower than the 5.74% MLP algorithm and 4.23% SVM algorithm. By comparison, the full convolutional calculation method is more efficient than other calculation methods in the detection rate of attack types such as Dos, Probe, U2R, and R2L. Therefore, the calculation method here is well adapted to computer network security protection requirements.

Authors: Lin Zhonghua , Gong Qingzhong
Published: June 2023

The hydraulic system plays the role of power transmission in the working process of construction machinery, but their complex structure leads to their frequent failure, which in turn leads to serious consequences. Therefore, this paper first takes the fault diagnosis and troubleshooting of the hydraulic system of construction machinery as the research theme and introduces the working principle of the hydraulic system of construction machinery and common fault mechanism and common methods of fault monitoring and diagnosis. Secondly, it proposes to analyze the key components of the hydraulic system based on the power bonding diagram theory and establish its bonding diagram model to analyze the working principle and power flow characteristics of key components. Finally, the pressure and velocity characteristic parameters are identified with the help of wavelet technology, and the energy distribution and energy entropy value of the hydraulic cylinder velocity signal are obtained by wavelet packet transform. The simulation results show that the wavelet-based analysis model proposed in this paper has good fault tolerance and robustness for fault diagnosis of the hydraulic system of construction machinery, and the correct rate of hydraulic pump fault diagnosis is up to 97%, with a correct average rate increased by 16%; the correct rate of hydraulic cylinder fault diagnosis is up to 95%, with a correct average rate increased by 13%. The wavelet analysis model can be widely applied to the fault diagnosis of hydraulic systems of various construction machinery, and it effectively improves the performance of hydraulic fault analysis systems and provides a key technology for fault identification and troubleshooting of construction machinery.
Study on the application of multi-angle imaging related technology in the construction process
Authors: Gao Guoping
Published: June 2023

The mufti-angle imaging technique is proposed to address the wall position offset and the side flaps and gate flaps caused by the sparse array in the ultra-wide band through-wall radar building layout imaging, using the characteristic that the azimuth upward distance profile is similar around the main flap but different around the side flap/gate flap. Firstly, after the backward projection algorithm obtains the wall image of each viewpoint, the mufti-directional two-dimensional matching filter is used to enhance the image of each viewpoint and eliminate the effect of side flaps and raster flaps. Then the images of each viewpoint are decomposed by combining the multistage transform, i.e., the non-down sampling contour let transform, and the obtained low-frequency components and high-frequency components are fused using the corresponding fusion rules, respectively. Finally, the final fused building layout image is obtained by non-down sampling contour let inverse transform. The simulation experimental data show that the running time of the method in this paper is 10.99s. It shows that the proposed method enhances the outline and detail information of the building wall, and the final fused image obtained has prominent wall image, clearer edge contours, and good retention of overall detail information. The quality of image fusion is greatly improved than other methods, which paves the way for subsequent fusion methods including chatterers such as construction building corners and windows and doors.

Published: June 2023

Under the new situation, the speed of economic development continues to accelerate, and under the influence of the modernization process, the transportation industry is more closely linked with the economy. To promote the sustainable development of the transportation industry, it is necessary to establish a scientific and effective economic statistics strategy to achieve steady economic growth. This paper designs a segmented time-varying parametric state space model based on the state space model to construct an economic statistical system for the transportation industry. By integrating and breaking the original design model, the structure, function, and statistical process of the system are optimized. The system is introduced into the transportation industry to analyze the application effect. According to the data, the economic revenue of the railroad transportation industry reached 464.293 billion yuan at the end of 2021, 45.48 times more than that of 10,208.81 billion yuan in 1986, and the market share increased from 23.23% in 2000 to 31.19% in 2021. The market share of waterway transportation industry, on the other hand, rose from 29.07% in 2000 to 32.87% in 2021. The share of capital investment in waterways and civil aviation continues to change in a downward trend from about 11% in the previous period. The economic statistics strategy can improve the economic efficiency of the transportation industry, so that the whole industry can gradually adapt to the current level of economic development and the needs of people’s life.
Títul Mobile visual media design based on digital media technology and augmented reality
Authors: Luo Baoquan
Published: June 2023

The reliance on shape-based parameters for traditional 3D multimedia visual behavior can significantly reduce the stability of image simulation. In this paper, the video feature enhancement method of wavelet and human eye vision is used to set the initialization parameters of the ant colony method calculation and calculate the video pixel to different food source distances as a way to obtain the amount of information of each path. The interface pixel affiliation is calculated to make a judgment on whether the amount of information is greater than the initial threshold. The contrast between the detail components of the interface at different scales is enhanced using the wavelet multistage method, and the video visual feedback enhancement is achieved by extracting the interface edge regions in each scale through the local shareholding method. Then the multimedia video representation of human behavior as silhouette sequence, extract the human behavior motion trajectory as large-scale multimedia visual behavior features, and extract the edge features of multimedia vision, and express the results as visual detail features in multimedia video. Finally, a multimedia visual human behavior state model is formed, and the patio-temporal sequence of the model is estimated by fusing it with particle filtering approximation inference to complete the behavioral simulation analysis of multimedia vision. The experimental results show that the average recognition rate of the method in this paper is as high as 98%, the accuracy of behavioral feature extraction is as high as 96%, and the error rate of modeling is 0.02%.

Authors: Tang Linye
Published: June 2023

Under the multiple driving of capital, new media and consumer group, the output value of Chinese animation industry keeps growing rapidly. Meanwhile, the quality of animation characters image determines the overall development level of the animation industry. This paper proposed a detail feature preservation-based 3D facial expression transfer method aiming at the design of 3D characters. By extracting the detail features of 3D facial model, the basic expression after removing the details was obtained. By using the improved joint learning method, the basic expression of the source model was transferred to the target model, and the feature modulus based on the Laplace factor was constructed. Finally, through the detail feature vector adjustment strategy, the target model with source basic expression was performed detail restoration. The multiple experiments show that the method proposed in this paper can transfer the expression of the source model to the target model without damage, and at the same time, preserve the personality detail features of the target model. Moreover, the animation expressions generated are real and natural, and the facial micro-movements of animation characters are rich, which positively affects the development of Chinese animation industry.
A multidimensional interpretation of Marxist globalization theory based on decentralized internet
Authors: Zhang Shunjun
Published: June 2023

To achieve a multidimensional interpretation of Marxist globalization theory, this paper provides a fecundation network facility based on a decentralized internet, thus overcoming various drawbacks of the network where traditional spatial services are located. In the Marxist theory of globalization, the rise from concrete rigor to abstract rigor is an important dialectical transformation of materialist epistemology. It is implied that Marx, based on the principle of mathematical expression of intuition and detail, refined, and deepened the paradigm itself through mathematical tools and mathematical methods, and used mathematical ideas to condense the theory of political economy, making the property of precision reflected in the logic of the paradigm. The 3PL model is established and the basic principles are accurately understood and grasped from mathematical logic according to the labor theory of value, surplus value theory and reproduction theory in Marxism, which provides an important generative logic for constructing a mathematical paradigm of Marxist political economy. The results of the study show that the output efficiency and benefits of fully cooperative networks (L = 0.92, Q = 281.5), after a long period of competition makes the output of the network less efficient, which in turn makes the network as a whole obtain lower returns (L = 0.73, Q = 96.18). In a competitive coexistence network structure, although there are competitive relationships at the core firm level, the network is not greatly affected by this (L = 0.83, Q = 202.92) instead, it will break the monopoly alliance and enliven the local economy. By constructing a rigorous and sophisticated mathematical and theoretical model, the theory of political economy can be made more abstract and scientific, and the analytical and explanatory power of the theory of political economy can be improved.
"Svag elev" som social representation i Statens offentliga utredningar
Authors: Friberg Therese
Published: June 2023

Classifications of pupils as ‘weak’ have featured during the last century in Sweden and are still present in contemporary descriptions of pupils. This study aims to develop knowledge about how ‘weak pupil’ as a social representation has been (re)produced in governmental inquires during 1923–2019 and explores how a temporal perspective might deepen the knowledge on a current classification such as ‘weak pupil’. In focus are the governmental inquiries concerning current or historical compulsory school forms. The following research questions are posed: To what extent has ‘weak pupil’ been present as a classification? How has ‘weak pupil’ as a social representation been (re)produced? Which patterns of stability and change can be identified in the (re)production of ‘weak pupil’ as a social representation? Through social representations theory, this study suggests that classifications and social representations of pupils as “weak” have been present during the last century. There are elements of both stability and change in the themes that construct “weak pupil” as a social representation, but there are indicators that ‘weak pupil’ as a social representation is more fossilized in contemporary writings. Perceptions of pupils in relation to perceptions of ’normality’ seem to be a stable construction over the last century.

Published: June 2023

The right to ensure an adequate level of work is guaranteed to every person and is controlled both by the state and other entities, in particular trade unions, which have a special legal status, which significantly distinguishes them from other entities authorized to supervise and control labor law compliance. Trade unions actually carry out continuous supervision of compliance with the norms of current legislation at each individual enterprise, institution of the organization, as they are independent from employers, which gives them more opportunities to carry out effective and efficient control over compliance with the norms of current legislation by the later. Trade unions are organizations that are formed on a voluntary basis and are non-profitable, because the purpose of their activity is to protect the rights, freedoms and interests of employees. Based on the analysis of scientific views of scholars, the author's definition of the concept of "trade union" is proposed in the article. The role and purpose of trade unions as subjects of supervision and control are revealed. The analysis of the current legislation is carried out, the norms of which fix the legal status of trade unions as subjects of supervision and control over compliance with labor legislation. The key features of the legal status of trade unions are highlighted, which distinguish them from other subjects of supervision and control over compliance with labor legislation.

Published: June 2023

O objetivo do trabalho foi caracterizar o ambiente institucional do sistema agroindustrial da carne bovina no Brasil e no estado do Paraná. Para tanto, foi desenvolvida uma pesquisa qualitativa descritiva por meio de dados secundários. Os resultados mostram que o ambiente institucional do Sistema Agroindustrial da carne bovina no Brasil apresenta grande complexidade e problemas de coordenação decorrentes da deficiência de instituições eficientes. Embora exista extenso regramento sobre o tema, o caráter voluntário de algumas regras e o desalinhamento entre elas, somada ao baixo poder de enforcement do Estado, parecem não contribuir para sua adoção. As deficiências relacionadas às instituições formais públicas contribuíram para que os agentes atuassem em um ambiente voltado à desconfiança, com possibilidade de ações oportunistas. As instituições informais, por sua vez, exercem forte impacto no ambiente institucional, pois os agentes possuem comportamentos peculiares que contribuíram para a formação desse ambiente. Sendo assim, defende-se a necessidade de considerar ambas as instituições para obter explicações mais amplas da dinâmica do ambiente institucional, sobretudo quando se trata de sistemas agroindustriais, devido à força das normas de comportamento dos agentes.

The use of diffusion magnetic resonance imaging tractography in supporting anatomical conflict between an uncal protrusion and the oculomotor nerve: A case report of isolated inferior rectus palsy
Authors: Kiss-Bodolay Daniel , Steffen Heimo , Vargas María Isabel , Schaller Karl
Published: June 2023

Background:

Isolated inferior rectus muscle palsy is a rare entity and even more rarely induced by an anatomical conflict. We report here a clinical case of third cranial nerve (CN III) compression in its cisternal segment by an idiopathic uncal protrusion in a patient presenting an isolated inferior rectus muscle palsy.

Case Description:

We report a case of an anatomical conflict between the uncus and the CN III in the form of a protrusion and highly asymmetrical proximity of the uncus and asymmetrically thinned nerve diameter deviated from its straight cisternal trajectory on the ipsilateral side were supported by an altered diffusion tractography along the concerned CN III. Clinical description, review of the literature, and image analysis were done including CN III fiber reconstruction using a fused image from diffusion tensor imaging images, constructive interference in steady state, and T2-fluid-attenuated inversion recovery images on a dedicated software (BrainLAB AG).

Conclusion:

This case illustrates the importance of anatomical-clinical correlation in cases of CN deficits and supports the use of new neuroradiologically based interrogation methods such as CN diffusion tractography to support anatomical CN conflicts.

Authors: Miyahara Kosuke , Okada Tomu , Tanino Shin , Uriu Yasuhiro , Tanaka Yusuke , Suzuki Koji , Sekiguchi Noriaki , Noda Naoyuki , Ichikawa Teruo , Fujitsu Kazuhiko
Published: June 2023

Background:

Extra-axial cerebellopontine angle (CPA) hemangioblastomas are rare clinical entity and surgical treatment is challenging due to the anatomical difficulties and multi-directional blood supplies. On the other hand, the risk of endovascular treatment for this disease has also been reported. Herein, we successfully applied a posterior transpetrosal approach to remove a large solid CPA hemangioblastoma without preoperative feeder embolization.

Case Description:

A 65-year-old man presented with a complaint of diplopia during downward gaze. Magnetic resonance imaging revealed a solid tumor with homogeneous enhancement measuring about 35 mm at the left CPA, and the tumor compressed a left trochlear nerve. Cerebral angiography disclosed tumor-staining fed by both left superior cerebellar and left tentorial arteries. After the operation, the patient’s trochlear nerve palsy improved dramatically.

Conclusion:

This approach offers more optimal surgical working angle to the anteromedial part compared to the lateral suboccipital approach. In addition, the devascularization from the cerebellar parenchyma can be performed more reliably than the anterior transpetrosal approach. After all, this approach can be particularly useful when vascular-rich tumors receive blood supplies from multiple directions.

Authors: Fuming Guo , Qiliang Xu , Haoxiong Chen , Xuecheng Huang , Junxing Yang
Published: June 2023

Introduction. Wound complications are common, difficult to manage, and carry a high economic burden. They are challenging to physicians and a burden to society. Case Report. An 86-year-old male with a history of diabetes was diagnosed with spinal suppurative osteomyelitis and underwent spinal debridement and debridement of dead bone, which required an incision of approximately 9 cm in length. Poor wound healing was noted on postoperative day 5, and wound healing had not been achieved by postoperative day 82. The periphery of the wound was stretched using a proprietary elastic therapeutic tape beginning on postoperative day 82, and daily routine disinfection was maintained thereafter. Wound healing was achieved after 2 months of the aforementioned routine. No additional wound changes were noted at the 6-month follow-up after wound healing was confirmed. Conclusions. Use of elastic therapeutic taping aided in healing a chronic nonhealing wound after spinal surgery in 1 case. The mechanism of action is discussed and analyzed to provide clinical evidence for such treatment.
The Novel Use of Cryopreserved Human Allograft in Extensive Hurley Stage III Hidradenitis Suppurativa
Authors: Matera David , Jacob Lisa
Published: June 2023

Introduction. HS is a debilitating dermatologic condition in which apocrine sweat glands become occluded, leading to severe inflammation. Treatment usually ranges from conservative management to surgical intervention with the goal of treating existing lesions while reducing the rate of recurrence, progression, and scarring. Depending on the surface area involved, autologous skin grafting may be difficult when donor sites are limited due to the extent of disease, previous surgery, or scarring. This case report examines the efficacy of cryopreserved human allograft as a surgical treatment of extensive HS. Case Report. A 37-year-old man presented with severe, refractory Hurley stage III HS in which cryopreserved human allograft was used to aid in wound contracture and granulation tissue formation. In addition, its use improved contour deformities and served as a bridge to autologous skin grafting, minimizing donor site size and morbidity. Conclusions. While autologous skin grafting is necessary for final wound closure, the use of cryopreserved human allograft provides biologic wound management that aids as a bridge to autologous skin grafting. As such, the authors advocate its use as a tissue scaffold in the management of severe, extensive HS and other dermatologic conditions requiring skin excision.

Introduction. The benefits of NPWT-T for the diabetic foot have been established. The addition of regular periodic irrigation with broad-spectrum antiseptic solution has been shown to reduce bioburden and total bacterial colonies; however, debate remains as to the clinical effect on diabetic foot outcomes. Objective. This study investigated the differences between NPWT-T and NPWT-I for treatment of the diabetic foot and the associated clinical outcomes. Methods. PubMed, Medline/Embase, the Cochrane Library, and Web of Science were searched for relevant literature published between January 1, 2002, and March 1, 2022. Keywords included “Negative Pressure Wound Therapy” AND “Instillation” OR “Irrigation.” Three studies with a total of 421 patients (NPWT-T [n = 223], NPWT-I [n = 198]) were included in the meta-analysis. Results. No significant differences were observed between NPWT-T and NPWT-I for BWC (OR, 1.049; 95% CI, 0.709-1.552; P =.810), time to wound closure (SMD, −0.039; 95% CI, −0.233-0.154; P =.691), LOS (SMD, 0.065; 95% CI, −0.128-0.259; P =.508), or AEs (OR, 1.092; 95% CI, 0.714-1.670; P =.69). Conclusion. Results of this systematic review and meta-analysis indicate that further RCTs are required to assess the role of NPWT-I in the management of DFU and DFI.

Published: June 2023

Introduction. PIs are very common in those with SCI and pose a significant health and economic burden. Optimal prevention strategies require rapid identification of high-risk populations. Objective. The authors examined risk factors for PI in persons with traumatic SCI, focusing on mechanism of injury and sociodemographic variables. Materials and Methods. Patients aged 18 years or older at the authors’ institution who had a traumatic SCI between January 1, 2002, and December 31, 2018 were included. Descriptive statistics and logistic regression analyses were conducted. Results. Of 448 patients, 94 patients (21%) had a violent SCI and 163 patients (36%) developed PIs. Violent mechanism of SCI was a significant predictor of a single (56% vs 31%; P <.001) or multiple PIs (83% vs 61%; P <.01), flap coverage (26% vs 17%; P <.05), and higher median stage PI (stage 4 vs stage 3, P <.05). Male sex (OR = 2.08; P <.05), complete SCI (OR = 5.51; P <.001), and violent mechanism of SCI (OR = 2.36; P <.01) were significant predictors on multivariate analysis. Increasing age at the time of SCI (OR = 1.01; P <.05) and unmarried marital status (OR = 1.77; P <.01) were predictive on univariate analysis. Conclusions. Patients of male sex, complete SCI, and violent mechanism of SCI may be at higher risk of PI development and would benefit from more intensive prevention initiatives.
The variation of surface propensity of halides with droplet size and temperature; Are the driving forces for the surface propensity of halides the same in planar interface and clusters?
Authors: Kwan Victor , Malek Shahrazad , Consta Styliani
Published: June 2023

Relative to a planar interface, nanodroplets are characterized by substantial mass density gradients between the interior and the surface regions and different forces when a sole ion is embedded within them. The radial number density of halide and alkali ions in aqueous clusters with equimolar radius up to approximately 1.4 nm, that corresponds to approximately 250 water molecules, has been extensively studied. However, the abundance of Cl-, Br- and I- on the surface relative to the bulk interior in these smaller clusters may not be representative of the larger systems. Indeed, here we show that the small droplet sizes with equimolar radius up to approximately 1.4 nm are significantly different in their structure and mass density and thus, in the relative surface abundance of halides from their larger counterparts composed of > 800 water molecules (equimolar radius > 1.75 nm). Starting from equimolar radius approximately 1.75 nm converging values in the ion location are observed. The chloride number density profile is the most sensitive to the droplet size and temperature and of the iodide least. The observed trend is that the larger the droplet is, the lower the relative surface abundance of chaotropic halides is. At elevated temperatures Cl- loses gradually its surface propensity, while I- partially preserves it. The relative interfacial free energy of solvation of the ions is in the range of a few kJ/mol.
Phase-diagram observation of liquid–liquid phase separation in the poly-L-lysine/ATP system and diagram-based application strategy
Authors: Nobeyama Tomohiro , Furuki Tomohiro , Shiraki Kentaro
Published: June 2023

Liquid–liquid phase separation (LLPS) is essential to understand biomacromolecule compartmentalization in living cells and to form soft-matter structures for chemical reactions and drug delivery systems. However, the importance of detail experimental phase diagrams of modern LLPS systems tend to be overlooked nowadays. Even for poly-L-lysine (PLL)/ATP system, one of the most widely used LLPS models, detailed phase diagram of LLPS have not been obtained. Herein, we report the first phase diagram of the (PLL)/ATP system and demonstrate the feasibility of phase-diagram based research design not only for understanding the physical properties of LLPS systems but also for realizing biophysical and medical applications. We established an experimental handy model of the droplet formation/disappearance process by forming a concentration gradient in a chamber as extracting a suitable condition on the phase-diagram including the two-phase droplet region. As a proof of concept of pharmaceutical application, we added a human immunoglobulin G (IgG) solution to PLL/ATP system. Using the knowledge of the phase diagram, we enabled to form IgG/PLL droplets clearly in the pharmaceutically required IgG concentration of ca. 10 mg/mL. This study provides a guidance for using the phase diagram to analyze and utilize LLPS

Published: June 2023

π-Conjugated nanoribbons attract interest because of their unusual electronic structures and charge-transport behavior. Here, we report the synthesis of a series of fully edge-fused porphyrin- anthracene oligomeric ribbons (dimer and trimer), together with a computational study of the corresponding infinite polymer. The porphyrin dimer and trimer were synthesized in high yield, via oxidative cyclodehydrogenation of singly linked precursors, using 2,3- dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and trifluoromethanesulfonic acid (TfOH). The crystal structure of the dimer shows that the central π-system is flat, with a slight S-shaped wave distortion at each porphyrin terminal. The extended π- conjugation causes a dramatic red-shift in the absorption spectra: the absorption maxima of the fused dimer and trimer appear at 1188 nm and 1642 nm, respectively (for the nickel complexes dissolved in toluene). The coordinated metal in the dimer was changed from Ni to Mg, using p-tolylmagnesium bromide, providing access to free-base and Zn complexes. These results open a versatile avenue to longer π-conjugated nanoribbons with integrated metalloporphyrin units.

Factors influencing pre-service teacher personal identity development
during professional practice
Authors:   , Jilina Polina
Published: June 2023

The concept of identity can be broken up into two constructs: personal and professional. Developing teacher professional identity is an important part of becoming a teacher. Research suggests pre-service teachers primarily develop their professional identity during professional practice. Personal and professional identities are interlinked, and conflict can arise when pre-service teachers take their personal identity on professional practice. In the past ten years, much research about pre-service teacher professional identity development had been completed, while personal identity was largely overlooked. This phenomenological study uses qualitative methods including ecomaps, semi-structured interviews, and field notes to investigate factors influencing primary school pre-service teacher personal identity development during professional practice. Reflexive thematic analysis revealed themes situated within Bronfenbrenner’s ecological systems, including factors that enable, challenge, or enable and challenge identity development. Findings suggest pre-service teachers’ individual aspects and contextual factors, primarily whānau, can influence identity development, and imply the role of resilience. This study poses implications for pre-service teachers, initial teacher education providers, educators, professional practice schools, and researchers.

Рассмотрены особенности геометрического и электронного строения молекулярных (AH), катионных (AH2+), цвиттер-ионных (A–H+), и анионных (A–) форм замещенных нафталинсульфокислот: 1-аминонафталин-8-сульфокислоты и 1-(N-фенил)аминонафталин-8-сульфокислоты (метод DFT B3LYP). Получены и проанализированы теоретические электронные спектры поглощения и испускания различных форм исследуемых сульфокислот. Показано на примере молекулярной формы 1-аминонафталин-8-сульфокислоты, что наличие внутримолекулярной водородной связи в конформере I приводит к смещению полос в спектре поглощения в коротковолновую область по сравнению с конформерами, в которых такие связи отсутствуют. Проанализирована взаимосвязь энергии и формы граничных орбиталей различных форм сульфокислот с особенностями электронных спектров поглощения. Показано, что теоретические спектры испускания катионной и цвиттер-ионной форм 1-(N-фенил)аминонафталин-8-сульфокислоты хорошо воспроизводят тенденцию экспериментальных спектров, в которых полоса с максимальной длиной волны смещается в длинноволновую область при переходе от кислой среды к слабокислой и нейтральной.

Introduction. From the materials of publicly available literary sources, we find the information that an express method of quantitative assessment of the level of somatic health based on bio-energy reserves cannot be used in the assessment of health both of highly trained athletes and young sportsmen of adolescent age (13-16 years old). The reason is the specificity of the impact of various types of physical exercises on the structure of energy metabolism of athletes during muscle activity. As for the problem of quantitative assessment of physical health of young athletes of prepubertal age (initial stage of sports training) according to the body’s bio-energy reserves, it remains unexplored. The aim of the research is the theoretical justification and practical use of the express method of quantitative assessment of the level of somatic health of young athletes aged 10-12 years according to bioenergy reserves. Material and methods. 113 young athletes aged 10-12 years took part in the study, who were divided into two groups: group А – sports that mainly develop speed and strength qualities (judo wrestling, fencing, football) (n=56); group B – endurance sports (skiing, swimming, track and field athletics: running for 800, 1500-meters race) (n=57). The control group (group K) consisted of 30 students aged 10-12 years of a general educational institution, who did not play sports. Results. The nature of changes in life and power indexes as important indicators of aerobic energy potential of the body of children who played various sports. Conclusion. Based on the conducted research, the authors of the article are of the opinion that the questions concerning the expediency to use an express method of quantitative assessment of the level of somatic health of young athletes aged 10-12 years in the context of their bio-energy reserves remains debatable. On the one hand, the absence of statistically significant differences, due to the influence of physical training of different orientation, in the nature of changes in life and power indices characterizing the various functions of the body in young athletes points out the expediency to use an express method in the practice of sports. On the other hand, statistically significant differences in indices of strength training of young athletes having different orientation of training exercises points out the opposite. The reason – significant differences in the structure of energy metabolism during muscle activity, which are determined by specificity of impact of training load on the body of athletes. The result of such impact is the factor of “acquisition” of some and ‘loss” of other functions of the body. And therefore, according to the authors, it is necessary to conduct additional research with the purpose of establishing the final result.

Soil electrical properties are important parameters to be considered during the design of several electrical installations. This study gives an insight into the impact of crude oil contamination on the soil’s electrical behaviors and suitable remediation technique for the contaminated soil. Crude oil was spilled on the soil and this soil was thereafter remediated with poultry (organic) manure and NPK 15:15:15 fertilizer for a duration of 12 weeks; thereafter, some of the soil’s electrical properties (electrical dielectric constant, electrical conductivity and electrical resistivity) were measured in accordance with the Institute of Electrical and Electronic Engineers standard guidelines. Results obtained revealed crude oil had negative impacts on the soil electrical properties; but the remediation agents alleviated these poor electrical properties of the contaminated soil samples. After the remediation programme, the dielectric constant of the contaminated soil treated with 0.5 kg manure (AXT 2) and 1 kg manure (AXT 3) declined by 56.38% and 47.21% respectively; while the contaminated soil treated with 200 g fertilizer (AXT 4) and 400 g fertilizer (AXT 5) declined by 57.49% and 64.54%respectively. The electrical conductivity of AXT 2, AXT 3, AXT 4 and AXT 5 soil samples increased by 46.48%, 50.89%, 32.84% and 41.70% respectively. Furthermore, the AXT 2, AXT 3, AXT 4 and AXT 5 electrical resistivity declined from 1362 Ωm to 579 Ωm, 1362 Ωm to 483 Ωm, 1362 Ωm to 719 Ωm, and 1362 Ωm to 594 Ωm respectively. This study’s revealed the relevance of remediating crude oil contaminated soil to preserve the electrical integrity of electrical installations.
The Media’s Representation of Cindy Gladue: An Analysis
Authors: Makepeace Jay
Published: June 2023

Cindy Gladue, a 36-year-old Cree Métis woman, was murdered in an Edmonton hotel bathroom in June 2011 while working as a sex worker. While much has been written about her death, the media’s news reporting has largely failed to adequately capture the nuances of Cindy’s death. This includes both the gravity of the individual crime perpetrated by Bradley Barton and the colonial gendered violences that made her death possible. Since Indigenous women are judged based on their post-mortem representation from the media, this essay analyses how the inadequate representation of Cindy Gladue’s murder contributes to the negative profilicity of missing and murdered Indigenous peoples. This inadequate representation then allows for the continuation of gender-based harm. I use a Critical Discourse Analysis (van Dijk, 2015) framework to link discourses used in international, mainstream Canadian, and Indigenous news sources to the ongoing missing and murdered Indigenous women and girls, two spirit plus (MMIWG2S+) crisis faced by Indigenous communities to situate and reassign responsibility for this gender-based violence
