Authors: Jiang Y.T. , Zhao Xinxin , Zhang J.G.
Published: October 2023

Since there are no typical working conditions in the field of engineering vehicles, this paper implements the construction of driving conditions based on Markov stochastic model and energy management strategy of a multi-mode hybrid mine dump truck based on dynamic programming algorithm under this background. Firstly, on the basis of existing vehicle driving data, we calculate the velocity transfer probability matrix with the Markov stochastic model, and then construct the vehicle driving condition after predicting the velocity. The constructed working conditions are applied to the energy management strategy of dynamic programming algorithm to calculate the energy consumption of the hybrid mining truck. It is proved that this construction method can be applied to the hybrid electric mine dump truck, and the DP based energy management strategy has lower energy consumption.
Research on Air Mass Flow and Pressure Control Method for the
Multi-Stack Fuel Cell System Based on Model Predictive Control
Authors: Xie Zhengchun , Gao Jianhua , Zhou Su
Published: October 2023

The multi-stack fuel cell system (MFCS) has the advantages of higher efficiency,
stronger robustness and longer life, and could be widely used in high-power
application scenarios such as automobiles, airplanes, trains, and ships. The
appropriate air mass flow and air pressure have a crucial impact on the output
power performance indicators of the MFCS. Considering that the designed
integrated air supply system for the MFCS has significant gas supply hysteresis
and strong coupling between the inlet air mass flow and air pressure of each
stack, this paper identifies multiple steady-state operating points of the fuel
cell system to obtain corresponding linear predictive models and establishes
corresponding predictive control algorithms. The Model Predictive Control (MPC)
algorithms are switched in real-time based on the current load throughout the
entire C-WTVC (China World Transient Vehicle Cycle) working condition. The
simulation results show that the designed MPC algorithm can control all inlet
air flow and air pressure of the MFCS (20kW/70kW/120kW) within the error range
of ± 2% of the expected target values, which is significantly better than the
PID control algorithm.

The activity of mining complexes leads to the formation of large volumes of mineral waste, and the Trans-Baikal region was no exception, on the territory of which,according to data for 2018, operating enterprises accumulated 725.5 million tons of waste. Overburden dumps, out-of-balance and substandard ores, as well as enrichment tailings, are a serious problem for the environment. In total, there are more than 30 tailing dumps on the territory of the Trans-Baikal Territory, of which 12 currently remain ownerless and pose a serious threat to the environment of settlements located in close proximity to man-made objects. Such objects are dangerous, first of all, by spreading dustlike particles to nearby territories, often containing toxic and radioactive elements, as well as heavy metals. It requires the use of special technologies adapted to the climatic conditions of the territory of Transbaikalia. In this regard, studies were carried out on the possibility of reclamation / conservation of the tailing dump of the Sherlovogorsky GOK, located in close proximity to the town of Sherlovaya Gora, Transbaikal region.

Authors: Hutagalung Rory Anthony , Soewono Arka Dwinanda , Darmawan Marten , Cornelius Aldo
Published: October 2023

Aquaponics with bio-floc can potentially offer sustainable food production with zero waste as it allows farming plants and fish simultaneously, whereby the former use fish waste as their nutrient sources, while the latter receives cleaner water from the plants in a closed-loop system. In the aquaponics system, additional nutrients are usually added to support optimal plant growth, but it is suggested that the amount of such chemical nutrients should be controlled to prevent any harm to the fish. Furthermore, the plant and fish growth rates are influenced by the nutrients and the culture media used. This study aims to examine the effect of nutrition (full-nutrient and half-nutrient treatments) and different types of culture mediums (rockwool, rockwool-perlite, and rockwool-husk) on the growth rates of pak choi (Brassica rapa) and catfish (Clarias gariepinus) using split-plot design. Findings show that the half-nutrient treatment yielded a 17.12% higher plant growth rate and 23.87% heavier catfish weight than the full-nutrient treatment, but these treatments did not affect the fish survival rate. It was also observed that using different culture mediums did not result in any significant difference.
The Impact of Industrialization on Economic Growth in Tonga
Authors: Yangailo Tryson
Published: October 2023

This study examines the impact of industrialization on economic growth in Tonga. The Tongan government has worked tirelessly to ensure that the country achieves and sustains industrialization to drive economic growth. This study was undertaken because of conflicting findings from previous studies on the nature of the relationship that exists between economic growth and industrialization. Some studies have shown that industrialization has a positive and significant impact on economic growth, while others have not. The study used secondary data from World Bank data statistics and specified a model where GDP was the dependent variable while industrial output, inflation, interest rate and exchange rate were the independent variables. Jamovi software was used to analyze the data using multiple regression analysis. The results show that industrialization and exchange rate have a positive and significant impact on economic growth in Tonga. This implies that the existing industrialization policy should be maintained and implemented accordingly. The government of Tonga should continue to provide a good and attractive environment for industrial growth in the country. Replication of this study in other countries is recommended and future studies are also recommended to consider the inclusion of other macroeconomic indicators such as FDI and others as variables.

Introduction

Low back pain (LBP) is a prevalent musculoskeletal condition that poses significant public health challenges. However, its epidemiology in Sub-Saharan Africa, especially in rural settings, remains largely unexplored. This study aimed to determine the epidemiology of LBP in a Nigerian Teaching Hospital.

Material and methods

This was a retrospective review of the records of all LBP cases seen at the rheumatology clinic from 2018 to 2022 in a Teaching Hospital in South-South Nigeria. The sociodemographic and clinical data, including disability scores, was extracted from the patients’ medical records. The data was analyzed using IBM SPSS version 25, and the level of significance was set at p < 0.05.

Results

Among 1,580 patients, 319 (20.2%) reported LBP. The mean age was 59.51 ±10.21, and the peak age incidence was 51–60 years. Low back pain was more prevalent in females (61.4%). Work-related factors (47.3%) such as heavy lifting (26.3%), prolonged sitting (19.4%), and poor posture (27.9%) were the prominent risk factors. Sedentary behavior (11.5%) and obesity (16.9%) contributed. Common clinical manifestations included difficulty standing or bending (73%), walking difficulties (67.7%), sleep disturbances (51.4%), and radicular pain (45.8%). Common etiologies were spondylosis (66.5%), spondylolisthesis (22.3%), disc prolapse (19.4%), spinal canal stenosis (15.4%), muscle spasm (12.2%), and tuberculous spondylitis (9.7%). Acute and chronic LBP constituted 12.2% and 79.9% of cases, respectively. In terms of disability, 33.5% had minimal, 44.5% had moderate, 15.4% had severe, and 6.6% had crippling disabilities.

Conclusions

Mechanical causes were the most implicated in LBP. Work-related factors and lifestyle choices contribute to the occurrence of LBP. Adjusting posture and lifestyle modification reduces LBP risk. Understanding its epidemiology is crucial for optimizing care and implementing preventive strategies.

Humans live in a close relationship with the mechanism of nature, and it has been a research topic for a long period of time. Historically, people have taken a lot of inspirations from nature and used creatures in nature as a source of their ideation for the purpose of solving diverse problems. At present, biomimic design converged with nature has been used in multidisciplinary fields such as architecture, medicine and fashion. Under these circumstances, this study attempted to suggest artistic values and a possibility of continuous expressions in beauty makeup through infinite uniqueness and diversity by applying biomorphic design. For this, an empirical research was performed based on the concept and design characteristics of biomorphism. In addition, the pictures on the websites were applied to biomorphic design processes. Based on the characteristics of each creature, three face artworks were created in a formative manner, using the colors which are good for each topic. The results found that the application of beauty and art to creatures in nature builds multilateral and unique ideas and, at the same time, makes creative face art possible by going beyond conventional standardized beauty. Therefore, it is anticipated that there would be further studies on creative face art design based on ‘biomorphic design methodology’ by upgrading the standards of body art through the continued development of unique and diverse makeup design.

Introduction: Oral health is extremely important for the quality of life and well-being. Findings reveal that people with special needs have difficulties in getting dental care, which increases their risk of oral diseases. The recommendations for dental examination are identical for patients with and without neurological impairment. This study aimed to assess the prevalence of caries and overall dental health among children with motor and mental disabilities in Northeastern Bulgaria. Methods: A total of 53 children with neurological impairment under the age of 18 were selected from Varna and Ruse from April to October 2017. Data on age, gender, height, weight, caregiver education level were collected. Information on oral hygiene behavior and diet was gathered as well. The 2013 World Health Organization standards for dental caries were used to assess the oral health status. The data were analyzed with the statistical package Jamovi v.2.2.2.0. Results: Children were divided into two groups – with predominantly motor or mental impairment. Both groups had high rates of caries and need for urgent dental treatment with no significant difference observed. The CPITN correlated positively with motor impairment (Spearman's rho= 0.393; p= 0.043). It was discovered that children with motor impairment had a higher prevalence of malocclusion than children with mental impairment (rho= -0.331; p= 0.016). The number of caries correlated as well with the type of occlusion (Spearman's rho=0.378; p=0.005), the dentition type (rho=0.343; p=0.012) and the age (rho= 0.372; p= 0.006). Conclusion: The study findings indicate that both types of neurological impairments were associated with a high frequency of caries and a significant need for urgent dental care. More frequent dental examination is thought to improve oral health. Nevertheless, more studies are required to substantiate this theory.

The study aims to investigate the genes associated with osmoadaptation seasonal variation in Tuz Lake by PICRUSt2. Dada2 pipelines were applied for filtering, dereplication, chimera identification, and merging paired-end reads to construct table.qza and rep_seqs.qza files. Therefore, the PICRUSt2 was applied to analyze the metabolic function of archaeal and bacterial diversity in Tuz Lake by using table.qza and rep_seqs.qza files. As a result of metabolic functions based on 16S rDNA amplicon data, the genes related to potassium accumulation played an important role in osmoregulation in Tuz Lake, where the archaea population was dominant. Furthermore, bacteriorhodopsin, halorhodopsin, and sensory rhodopsin functions were determined. The abundance of bacteriorhodopsin and halorhodopsin were increased in summer and spring, respectively.

Onde (não) entram voz universal e sensus communis nos juízos-de-gosto?
Authors: Guimarães Rômulo Eisinger
Published: October 2023

Seja uma das tarefas da Crítica do Juízo a fundamentação transcendental de uma faculdade que, como Entendimento e Razão, possui a priori seus princípios legislantes. Em virtude desta fundamentação atribui Kant à faculdade do Juízo "e ao sentimento de prazer envolvido em juízos-de-gosto estéticos“ validade universal. Contudo, em meio ao segundo momento da Analítica do Belo, afirma Kant que quem profere um juízo-de-gosto "crê ter em seu favor uma voz universal (baseada num sensus communis) e reivindica a adesão de qualquer um" (KU, AA 05: 216). Sendo assim, voz universal e sensus communis parecem colidir com a fundamentação transcendental dos juízos-de-gosto: porque ou reivindicamos universalidade graças à sua localização transcendental; ou porque, proferindo tais juízos, cremos ouvir uma voz universal. O presente artigo se debruça sobre algumas obscuridades da argumentação kantiana referente às figuras de voz universal e sensus communis em juízos-de-gosto, numa tentativa de situá-las no contexto da terceira Crítica.
Seria Kant um determinista? Considerações acerca da solução da terceira antinomia
Authors: Silva Luciano Vorpagel da , Pellizzaro Nilmar
Published: October 2023

Este estudo é uma reconstrução crítica da solução de Kant ao suposto conflito entre a causalidade natural e causalidade por liberdade. Ao contrário do que pensam os críticos, a causalidade natural não pode ser interpretada nos termos do determinismo, já que isso conduziria a um colapso do sistema kantiano. Quanto à liberdade transcendental, Kant chega apenas a um conceito problemático, não contraditório; Quanto à liberdade prática, ela exerce uma ação efetiva no mundo dos fenômenos, embora não possa ser provada na Dialética e figure apenas como um postulado necessário. Diferente do que pensa Allison, a liberdade prática não pode ser considerada como relativa ou semicrítica, mas exige um caráter absoluto, o qual deve estar alinhado com a causalidade natural, seja esta uma causa material ou espiritual.
A imaginação e a construção doutrinária da Estética Transcendental
Authors: Sehnem Claudio
Published: October 2023

O objetivo deste trabalho é expor aquilo que se pode chamar de «a parte estética» do juízo determinante, ou seja, do juízo em sua tarefa cognitiva. Quer se desenvolver aqui a ideia de que a Estética Transcendental só se apresenta como uma doutrina justamente pela presença do fenômeno a ser conhecido, que põee a funcionar todo aparato cognitivo típico da imaginação. Certamente, deixando aqui de lado a Analítica dos Princípios, a síntese tripla é, neste sentido, a «construtora» prévia desta doutrina estética, sobretudo se tomarmos como ponto de partida as afirmações de Kant, segundo as quais o espaço e o tempo são produtos da imaginação.
Livre-arbítrio, corpo e alma imortal, em Kant
Authors: Jorge Filho Edgard José
Published: October 2023

Investiga-se a relação entre o livre-arbítrio e o corpo, em Kant. Procura-se compreender a cadeia de relações do livre arbítrio com as inclinações, o sentimento de prazer e desprazer, as sensações, os sentidos externo e interno e o corpo. Com base em tal compreensão, apresenta-se certa interpretação da concepção kantiana da imortalidade da alma. Argumenta-se que o livre-arbítrio é necessariamente condicionado pelo corpo vivo sensível (humano) e que, portanto, a alma imortal, enquanto existência e persistência infinita da personalidade do mesmo ser racional, que é indissociável do livre-arbítrio, depende da conexão necessária da alma com o corpo vivo sensível (humano). Levantam-se duas dificuldades concernentes à quela interpretaçío da imortalidade de alma e enfrenta-se a primeira delas mediante uma argumentação baseada na doutrina kantiana da comunidade ética e da legislação ética pública.

Published: October 2023

The study sought to evaluate the significance of government regulations on the relationship between financial technology and financial inclusion of Small and Medium Enterprises in Kenya. This study emanates from the Doctoral dissertation of the first author where the co-authors served as supervisors. Technology, Organization and Environment Theory and Financial Intermediation Theory were utilized. The study adopted explanatory research design. The top 100 Small Medium Enterprises in Kenya constitute the target population and the sample size was 200 based on purposive sampling technique and simple random sampling where two respondents were picked from each Small Medium Enterprises of interest. A response rate of 81.5 percent was achieved. The study used multiple regression analysis and it was established that government regulations had significant moderation effect on the relationship between financial technology and financial inclusion of small and medium enterprises in Kenya. The study recommends that the existing transaction limits should be reviewed in line with economic conditions of the country. Government should ensure that favorable lending rates are put in place so as to further enhance the level of financial inclusion of small and medium enterprises in Kenya. Government guidelines on screening of customers should be favorable to business owners and stringent requirements should be discouraged.

Published: October 2023

This study aimed to evaluate the effectiveness of inflating the urinary bladder immediately before cesarean section (CS) in reducing the chances of bladder injury in high-risk patients. This was a prospective randomized controlled trial. The study was conducted in Obstetrics and Gynecology Ward 8, Jinnah Postgraduate Medical Centre (JPMC) Karachi, from April 06, 2021 to September 30, 2021. Three hundred twenty-eight pregnant women who delivered by cesarean section and had one or more risk factors for urinary tract injury were recruited. The women were divided into two groups: Group A underwent bladder inflation using a triple-way Foley catheter before CS, while Group B served as the control group without bladder inflation with a Foley catheter before CS. In this study, urinary bladder injury was found in 5.5% of women in Group A who had bladder inflation, while 12.2% of women in Group B without bladder inflation had bladder injury. The efficacy in Group A and B was 94.5% and 87.8%, respectively. The results showed a significant association between the study group and urinary bladder injury (p=0.032). The study significantly reduced urinary bladder injuries, surgery time, blood transfusion, and hospitalization. Inflating the urinary bladder before cesarean section should be used to prevent bladder injury in women with risk factors for dense bladder adhesion.
