Inflation-Unemployment Trade Off: Evidence from Pakistan
Authors: Afzal Muhammad , Awais Samia
Published: August 2023

High economic growth, price stability and low unemployment are the most enviable macroeconomic goals. The success of government policies is reflected in low inflation and low unemployment. The nature and costs of inflation and unemployment can have vital impact on the economy and society. Unemployment situation in Pakistan has aggravated because of rapid population growth, lacklustre economic growth, fiscal indiscipline, escalating debt-servicing and non- development expenditure which have adversely affected Pakistan economic development and poverty reduction. Import prices and fiscal indiscipline are the major causes of inflation. The empirical results show that the Phillips curve holds in Pakistan.Â  The reduced-form Phillips curve structure reveals that the expected inflation is significant for all periods.The current unemployment exceeds the lagged unemployment which means that unemployment has been increasing at an increasing rate and this difference causes a significant change in current inflation. Lack of governance or bad governance has remained the crux of the problem. Unless foreign policy objectives are rationalised and good governance is assured, economic problems will haunt the policy- makers and the resolution of economic problems may assume pitiless faÃ§ade

The paper considers approaches to optimization of known designs of traditional rolling stock beam. The authors have studied a classic case of loading a console with force. They have gained values of stress and full deformations for a console with a rectangular cross-section. The authors have studied a possibility to optimize design by means of decrease of mass and prevention of actual stress above the limit of material fluidity (local stress hasn’t been considered). On the basis of analysis of gained results they have proposed a more rational profile of a console - its construction is optimized along a horizontal transverse axis. Verification of stress and deformations of the optimized model have been carried out in a calculation module, Results show a significant improvement of workability of the optimized console design that differs in reduced mass without losing in strength and rigidity.

Estimation of passenger traffi c volume based on data on the rotation of bank cards between payment terminals
Authors:   Ural state university of railway transport (USURT), Martynenko Alexander V.
Published: August 2023

In this paper, the issues related to the use of big data on the rotation of bank cards between payment terminals are considered. Such data correlate well with passenger traffic (especially intercity) and therefore can be used, for example, to assess the relative congestion of individual sections of a network. However, this is not enough for some other aspects of modeling, therefore the study suggests the approach for estimating the amount of passenger traffic based on data on the rotation of bank cards between payment terminals.

Introduction: The COVID-19 pandemic has presented numerous challenges to healthcare systems. As the number of affected individuals continues to rise, it is crucial to find preventive, diagnostic, and therapeutic approaches. This study aims to describe different COVID-19 sequelae within a Primary Health Care population.
Methods: A retrospective cohort study was conducted in adults diagnosed with COVID-19 from March 2020 to April 2022, excluding pregnant women, minors, nursing home residents, hospitalizations, and deaths. Data was gathered from surveillance records on the Trace COVID-19® platform, a pre-set original questionnaire (which included the Portuguese version of the World Health Organization’s Quality of Life Assessment Instrument), and, if needed, patient electronic health records. Information on sociodemographic and clinical characteristics of acute COVID-19 was collected along with long COVID symptoms.
Results: This study included 284 patients, aged 19 to 99 years old. The five most prevalent acute COVID-19 symptoms were fever (50.0%), tiredness (48.2%), myalgias (44.7%), dry cough (37.7%) and odynophagia (36.3%). Symptoms related to the neurological system (23.2%) and tiredness (22.9%) were the most prevalent in long COVID symptoms. Acute tiredness and arthralgia were associated with all long COVID outcomes. The associations between acute COVID-19 symptoms with long COVID outcomes were stronger for anosmia [OR = 5.07, 95% confidence interval (CI) 2.49 - 10.36, p < 0.001] on a neurological chapter, acute tiredness for long lasting tiredness (OR = 4.07, 95% CI 2.07 - 8.02, p = 0.041), fatigue for muscles and/or bones chapter (OR = 7.55, 95% CI 3.06 - 18.66, p < 0.001), tiredness on an endocrine/hormonal chapter (OR = 6.54, 95% CI 2.37 - 18.04, p < 0.001), dyspnea for respiratory symptoms (OR = 5.67, 95% CI 1.92 - 16.74, p = 0.002) and fever for stomach or intestine symptoms (OR = 8.06, 95% CI 2.55 - 25.47, p < 0.001). Almost all quality of life dimensions were negatively associated with the number of long COVID symptoms.
Conclusion: A higher number of acute symptoms, as well as the presence of specific COVID-19 symptoms were associated with reported symptoms ≥ 12 weeks after infection. In the studied population, an increased number of symptoms in both acute and long COVID had a significant negative impact on the perception of overall quality of life. The identification of these relationships could provide a new perspective for post-COVID care.

Authors: Yepie Armand , Traore Moctar , Yaovi Mensah , Anoumou Michel
Published: August 2023

Epiphyseal dislocations and fractures frequently occur in children and adolescents. However, these injuries seldom involve the distal femur, and bilateral cases are even rarer. We present an unusual case of bilateral epiphyseal detachment of the femur in a 21-year-old man who was involved in a traffic accident. Open reduction and fixation surgery were performed 5 days after the incident. The patient experienced favorable progress, with consolidation occurring at 3 months. No lower limb length discrepancies were observed at the 20-month follow-up. In summary, bilateral distal femoral epiphyseal detachment is an uncommon condition that can be effectively treated through surgical intervention.
Free tissue transfer for reconstruction of axillary defects: two case reports
Authors: Bathini Asha Deepthi , Ravula Parvathi , Jammula Srinivas , R Srikanth , Pereira Priyanka
Published: August 2023

Axillary defects need pliable, vascular tissue to cover the critical structures traversing the axilla and to allow near-normal range of motion in the shoulder. Although local flaps are the first choice, free tissue transfer is a good option when local tissues are injured or scarred. Herein, we report two cases of axillary defects that were reconstructed using anterolateral thigh free flaps. One was a post–electric burn axillary defect for which a thoracoacromial pedicle was used as the recipient, and the other was a posttraumatic axillary defect with the transverse cervical vessels as the recipient. In both patients, the flap survived well with no complications and resulted in adequate functional recovery. In large defects of the axilla with a scarcity of local tissues, free flaps can yield optimal results. The proper selection of recipient vessels and a donor flap with adequate pedicle length impact the outcomes of such reconstruction.

Published: August 2023

HIGHLIGHTS

Monochorionic monoamniotic (MCMA) twin pregnancy has a significant risk of perinatal morbidity and mortality, including intrauterine fetal death (IUFD).
The risk of prematurity, the risk of death due to MCMA complications, the availability of the NICU, also high costs on preterm care were factors in deciding to terminate the pregnancy.
The ideal time to deliver monochorionic twins in order to reduce the risks of cord entanglement, growth discrepancies, and intrauterine fetal death is still a point of controversy.
Early diagnosis, intensive antenatal monitoring, patient and family decision would contribute to antenatal mortality reduction.

 
ABSTRACT
Objectives: To present the management of monochorionic monoamniotic (MCMA) twin pregnancy.
Case Report: Advanced prenatal treatment has improved the prognosis for Monochorionic Monoamniotic (MCMA) pregnancies; however, there is still no agreement on how to handle MCMA twins. The authors report 2 cases of monoamniotic monochorionic twin pregnancies. In the first case, a 30-years-old primi pregnant woman detected MCMA at 14 weeks of gestation; no complications related to MCMA were found; she planned delivery at 32 weeks, but one of the babies died in the womb at 31/32 weeks pregnant, a live baby born by cesarean section. The second case was a 36-year-old pregnant woman, on her third pregnancy, diagnosed with MCMA after 12 weeks of pregnancy, no complications related to MCMA, the baby was born at 32 weeks pregnant, and both babies survived. The management was the same in both cases, but different outcomes were obtained; in case 1, the baby died allegedly due to cord entanglement, which could not be detected during pregnancy.

HIGHLIGHTS

Testosterone level correlates with FSFI score, showing that sexual function correlates with hormonal physiology.
FSFI is a valid and useful tool in measuring sexual function.

 
ABSTRACT
Objective: This research aimed to analyze the correlation between testosterone levels and sexual function in postmenopausal women.
Materials and Methods: This research was a descriptive observational study with a case series approach conducted at Aras Kabu Health Center Outpatient Polyclinic from May to August 2022. The normality test was carried out using the Shapiro-Wilk test. If the data were not normally distributed, data would be analyzed using the Spearman correlation test. If the data were normally distributed, the data analysis would use the Pearson correlation test.
Results: There was a significant relationship between Female Sexual Function Index (FSFI) score with testosterone levels and duration of menopause with p<0.05. The degree of correlation found was 0.619 between testosterone levels and FSFI scores, indicating a moderate and significant positive correlation. A correlation degree of 0.482 was found between FSFI and length of menopause which indicated a significant moderate positive correlation, while the degree of correlation between testosterone levels and length of menopause was found to be 0.711, showing a strong and significant positive correlation.
Conclusion: There is a significant relationship between FSFI scores with testosterone levels and duration of menopause as well. There was also a significant relationship between testosterone levels and the duration of menopause.

Authors: Swain Monali , Ghosh-Laskar Sarbani , Patil Roshankumar , Budrukkar Ashwini , Agarwal Jaiprakash
Published: August 2023

Radiotherapy is an integral part of the management of head and neck cancers, both in radical and adjuvant settings. Traditionally, similar radiation dose and fractionation schedules have been used based on tumor stage with variable outcomes indicating “one size does not fit all”. In the era of precision medicine, though we have achieved physical precision with technological advancements, we have yet to attain biologic precision. In the current review, we have highlighted the different aspects of precision oncology such as hypoxia targeting, radiomics and radiogenomics, radiobiologic targeting, and big data. The review also discusses various potential therapeutic targets and approaches in head and neck cancer management that might help to increase radiosensitization, which in turn increase survival, and quality of life. This can be incorporated into the armamentarium of radiation oncology in all the phases of radiation planning, from diagnosis to treatment to the prognosis and management of long-term side effects. Biologic precision can be applied in the clinic to provide individualized, personalized treatment in the future.
Ultrasonographic fatty liver indicator (US-FLI): a reliable biomarker for non-invasive NAFLD stratification
Authors: Ballestri Stefano , Lonardo Amedeo
Published: August 2023

Here, we comment on a recent article supporting the use of the ultrasonographic fatty liver indicator (US-FLI) as a point-of-care biomarker to be used in the community to rule out nonalcoholic steatohepatitis (NASH). To this end, we discuss definitions and characteristics of US-FLI, and we critically summarize the principal studies published from 2012 to 2023. We conclude that US-FLI exhibits high reproducibility. It finds utility across both the pediatric population and the point-of-care settings. Furthermore, it demonstrates a robust correlation with metabolic derangements, and also serves as a predictive tool for varying grades of hepatic steatosis and important liver histology endpoints. Notably, it excels in its capacity to differentiate between bland steatosis and true NASH. However, US-FLI reportedly exhibits limited accuracy among patient populations with obesity. Finally, we propose a detailed agenda to advance research on US-FLI.

No contexto corrente de pandemia de Covid-19, a economia solidária nos ensina que o dinheiro não deve ser a prioridade, mas sim as pessoas e o cuidado com a natureza. Diante disso, o objetivo deste trabalho é descrever as atividades de incubação, capacitação, intercâmbio e prestação de assessoria técnica e tecnológica prestados aos EES em Santana do Livramento/RS pela Incubadora de Empreendimentos Econômicos Solidários na Fronteira da Paz. Criada em 2015, ela é fruto de uma parceria entre a Universidade Federal do Pampa (Unipampa), a Universidade Estadual do Rio Grande do Sul (Uergs) e o Instituto Federal Sul Rio-Grandense (IFSul), que possuem campus em Santana do Livramento/RS. Mesmo com falta de apoio e com a Pandemia da Covid-19, temos a certeza de que a incubadora deve continuar, ser fortalecida e acompanhar a caminhada desse movimento social que é resistência diante das desigualdades que corroem as sociedades capitalistas.
TERRITÓRIO MARCADO PELA VIOLENCIA
Authors: Lira Elizeu Ribeiro
Published: August 2023

Este trabalho trata-se de um estudo baseado na materialidade histórica dos fatos, sobre a destruição dos territórios da nação indígena Krahô. Faz parte, também, de um conjunto de ensaios resultante dos debates entre alunos do Mestrado em Geografia da Universidade Federal do Tocantins (Campus de Porto Nacional). Na busca por analisar os processos de violências contra os índios Krahô na defesa de seu território, verificou-se que o massacre de 1940 representa a centralidade da questão. As relações sociais estabelecidas entre indígenas e camponeses foram depreendidas a partir do acesso a arquivos e bibliografia sobre o assunto, além de trabalhos de campos. As relações conflituosas mantidas entre os Krahô e a frente de expansão Pastoril, sobre o consentimento do Estado e da Igreja, resultou na destruição do território tradicional (cosmologicamente infinito) no sul do Maranhão, e na demarcação de um novo território confinado, finito e descontínuo no município de Itacajá, Nordeste do estado do Tocantins.
INFLUÊNCIA NEOLIBERAL NA CONSTRUÇAO DOS GRANDES EMPREENDIMENTOS HIDRELÉTRICOS QUE IMPACTAM O ESTADO DO TOCANTINS
Authors: Foschiera Atamis Antonio , Coelho Silmar  Cardoso Araújo
Published: August 2023

O neoliberalismo surge em oposição às teorias que defendiam o Estado intervencionista e de Bem-estar. No Congresso de Washington, realizado no ano 1989, se estabeleceram medidas que deveriam ser seguidas pelos Estados para se adequarem ao neoliberalismo, sem as quais os mesmos não obteriam novos financiamentos de agências e organismos de financiamentos internacionais. Este artigo busca fazer uma reflexão sobre a influência neoliberal na matriz energética assentada em grandes empreendimentos hidrelétricos que impactam o estado do Tocantins. Foram consideradas as usinas hidrelétricas Luís Eduardo Magalhães (Lajeado), Peixe/Angical, São Salvador e Estreito. A metodologia utilizada levou em consideração referências bibliográfica sobre o tema, bem como se utilizou de dados documentais, principalmente dos relatórios de impactos ambientais dos empreendimentos em análise. Os empreendimentos hidrelétricos analisados tiveram grande participação de capital privado, tanto nacional como internacional, na formação de seus consórcios. Não havia grandes usinas hidrelétricas em território tocantinense até a construção das aqui analisadas, por isso não houve privatização desse tipo de empreendimento.

A presente pesquisa trata de uma análise da Estação Ecológica Serra Geral do Tocantins. localizada nos estados do Tocantins e da Bahia, tendo como principal objetivo analisar a ação do fogo, entre os anos de 1998 e 2022. Como metodologia se utilizou técnicas de Sensoriamento Remoto tendo como base a subtração de imagens, ou seja, a aplicação do Índice de Vegetação por Diferença Normalizada (NDVI). Para isto, utilizou-se o software QGis, versão 2.14 e as imagens de satélites Landsat 5, 7 e 8 e Ressourcesat – 1. Deste modo, foram identificadas áreas atingidas pelo fogo e as alterações ambientais decorrentes do mesmo. De modo geral, observou-se uma intensa ação do fogo sobre a vegetação do Cerrado, no período analisado, bem como uma redução da sua ação, na área, o que pode estar associado as mudanças de uso e ocupação da terra e ao Manejo do Fogo Integrado do Fogo (MIF) implantado na estação ecológica.

Este trabalho está direcionado para o desenvolvimento de modelo matemático sustentado nos preceitos das Integrais-Fuzzy, focado na geração de índices de qualidade da mobilidade urbana. Para tanto se desenvolve pesquisa exploratória ex-post-facto, pois pretende-se gerar um diagnóstico sobre as condições da movimentação na cidade, baseando-se na coleta de dados sobre as percepções dos usuários nas viagens cotidianas. Tal modelo pode ser utilizado de forma rotineira para geração de série histórica, promovendo melhoria do processo decisório de organismos públicos. Para teste e validação do modelo desenvolveu-se um estudo de caso baseado em pesquisa realizada em outubro de 2020, na cidade do Rio de Janeiro. O modelo apresentou-se estável e coerente após a análise dos seus resultados, pelo cruzamento dos índices gerados com questão reflexiva sobre a mobilidade. O diagnóstico dos usuários da cidade analisada é que a qualidade é ruim, com IQMU igual a 4,07 no universo de discurso [0,10]. Pontuaram-se também as percepções dos usuários quanto aos modos de transporte, com destaque para melhor nota para táxi-frete (IQM = 5,15) e pior grau para bicicleta (IQM = 3,12). Os resultados também foram avaliados organizando-os pelas características dos respondentes (gênero, faixa etária e formação) e pela condição das viagens (tempo de deslocamento e quantidade de baldeações).
FUNDAMENTOS DA EDUCAÇÃO AMBIENTAL NO BRASIL E EXEMPLOS DE PRÁTICAS EDUCATIVAS MUNICIPAIS
Authors: Francisco Alyson Bueno
Published: August 2023

A educação ambiental no Brasil está em processo de adesão da prática pedagógica desde a década de 1990, sendo oficializada por uma política nacional em 1999. O meio ambiente precisa ser tratado mais do que um eixo transversal, sendo parte integrante da realidade dos educandos no século XXI, a partir dos princípios de sustentabilidade, interdisciplinaridade e complexidade. As práticas educativo-ambientais podem ser aplicadas pela corrente crítico-reflexiva de Paulo Freire no contexto da leitura de mundo feita pelo educando diante dos problemas ambientais de sua localidade. Um dos principais exemplos de práticas educativo-ambientais é a realização de trabalhos de campo em microbacias hidrográficas. As práticas educacionais e ambientais possuem fundamentações legais e os docentes podem apoiar suas metodologias e práticas. Como exemplo de prática educativo-ambiental existem visitas em parques ecológicos criados em espaços públicos de antigas áreas degradadas, a fim de despertar a conscientização de alunos do ensino fundamental para as práticas respeito à natureza e aos espaços públicos.

Chemicals in Essential Oils of Phlomoides rotata (Benth. ex Hook. f.) Mathiesen and Their Antioxidant Activities Potential
Authors: Pan Zheng , Xie Chen , Yan Xiao Tong , Su Yong Mei , Ul Haq Anwar , Wang Jian
Published: August 2023

Due to the low content, few studies are focused on the essential oils (EOs) of Phlomoides rotata (Benth. ex Hook. f.) Mathiesen (syn. Lamiophlomis rotata (Benth.) Kudô. This plant has been used to treat rheumatic arthritis and grasserie in China. However, such EOs may have important pharmacological activities such as anti-cancer. To identify the chemical markers (CM) in the EOs and evaluate their antioxidant activities (AAs), we firstly conduct a thoroughly investigation on their chemicals and AAs, to the best of our knowledge. Light yellow EOs with fresh and elegant smell are obtained by hydro-distillation with average yield 0.11% (volume mL/weight g). The crystals are separated from the EOs through cryoprecipitation, respectively. A total of 81 components are qualified and quantified in the EOs, crystals and EOs removed crystals, in which 44 ones are first reported. As for content, the main compounds are long-chain fatty acids (FAs) and their esters. The most abundant one n-hexadecanoic acid (palmitic acid, PA) accounting for 43.15-54.8%, 58.49-64.57% and 15.9-41.1%, in the EOs, crystals and EOs removed crystals, respectively. Seven compounds including PA, tetradecanoic acid, linoleic acid, oleic acid, methyl hexadecanoate, hexahydrofarnesyl acetone and phytol can be chosen a the CMs in these EOs. The AAs are evaluated through in vitro assays. PA presents pro-oxidant activities in a concentration dependence manner. Usually, the EOs removed crystals demonstrate stronger AAs, and the crystals demonstrate weaker AAs compared with that of the corresponding EOs, which is related to the different content of PA in these samples. This study can give some hints for the utilization of such EOs which are abundant in FAs such as PA.
Making a Grammar Checker with Autocorrect Options Using NLP Tools

Published: August 2023

Our natural language approach concerns syntactic analysis using a dedicated Javascript library - wink-nlp - and semantic analysis based on Prolog programming language, facilitated by another Javascript library - tau-prolog - that allows defining logical programs, declaring rules and checking for goals inside Javascript language. Firstly, our program splits the original text into sentences, than into tokens and identifies each part of the sentence, dynamically maps entities into Prolog rules, then check the spelling accordingly to the Definite Clause Grammar (DCG) by querying the pre-defined program for initial goals (the sentence itself). Basically, we let the parser infer its own rules from the syntactic point of view, then check the grammar from a semantic perspective against the DCG inside the same work flow or pipeline of steps.The provided article combine the usage of wink-nlp and tau-prolog packages for natural language processing (NLP) and understanding (NLU), and demonstrates the need of a supplementary logic layer based on beta reductions over lambda expressions.
A Methodological Approach for Data Collection and Geospatial Information of Healthy public Spaces in Peripheral Neighborhoods. Case Studies: La Bota and Toctiuco, Quito-Ecuador
Authors: Medina Ana , Mosquera Diana , Gallegos Francisco
Published: August 2023

Adequate public spaces and urban green areas are key criteria for urban development and infrastructure implementation of healthy cities. Latterly, there has been an increasing number of research methods using artificial intelligence (AI) to monitor, quantify, and control the state of these spaces with an aim towards pioneering research in Urban Studies. However, in informal areas, open-data access tends to lack adequate and updated information, making it difficult to use AI methods. Hence, we propose a methodology for restricted open data collection and preparation for future use in machine learning or spatial data science models for similar areas. To that extent, we examine two peripheral and low-income neighborhoods in Quito, Ecuador, La Bota and Toctiuco, to analyze their public spaces, urban green areas, points of interest, and road networks, and how they address healthy cities criteria. We develop an original methodological approach that combines an index of proximity, accessibility, quantity, and quality of these spaces with geospatial and network analysis techniques. Results indicate that the connectivity and structure of these spaces are centralized and nodal, representing exclusion and segregation. This work provides insights on potential healthy spaces, and information to urban planners and policymakers in decision-making for healthy urban infrastructure.
Species Distribution Model (SDM) Predicts the Spread of Invasive Nile Tilapia in the Sensitive Inland Water System of the Southeastern Arabian Peninsula Under Climate Change
Authors: Esmaeili Hamid Reza , Eslami Zohreh
Published: August 2023

In the present study, we implemented species distribution models (SDMs) to determine the potential invasive distribution range of a cichlid fish, Nile tilapia, Oreochromis niloticus, in a very sensitive inland water system in the southeastern Arabian Peninsula where it is now established and spreading. By using the “Biomod2” package, and the latest CMIP6 climate data, four single species distribution models and EM were built, and the results were evaluated by operating characteristic (ROC) and the true skill statistic (TSS). Based on the relative importance of climate factor analysis the mean diurnal range and precipitation seasonality were useful predictors of habitat suitability for O. niloticus. The response curve analysis indicated that the presence probability of O. niloticus decreased with increasing mean diurnal range and decreasing precipitation seasonality. The suitable distribution ranges for O. niloticus in the studied area were mainly distributed in the northeast of this region. The ensemble model results specified a significant impact of climate change on O. niloticus distribution, so highly suitable areas for this species will be reduced, while areas with low to moderate suitability increase slightly or remain unchanged. Based on the available data, Nile tilapia fulfills all four criteria to be considered as an invasive species: colonization in a new area, direct or indirect impacts of anthropological activity on its distribution range, geographical discontinuity between its native area (Africa) and the Arabian Peninsula (remote dispersal), and finally, its successful breeding in situ without human assistance resulting establishment of this biopollutant. Species distribution modeling provides insights into the factors that can reduce the risks and negative impacts of this biological pollutant on aquatic ecosystems of the southeastern Arabian Peninsula which harbors about 22 recognized fish species in 16 genera, 10 families, seven orders, and a class including 20 natives (seven endemic) species.

Published: August 2023

Cotton cultivation and sustaining its productivity is challenging in temperate arid regions around the globe. Exploring suitable cotton cultivation areas to improve productivity in such climatic regions is essential. Thus, this study explores the ecologically suitable areas of cotton cultivation using the Maxent model, having 375 distribution points of long-staple cotton and various factors, including 19 climatic factors, 2 terrain factors, and 6 soil factors in Xinjiang. The area under the curve (AUC) of the predicted results was greater than 0.9, indicating that the model's predictions had fairly high accuracy. However, the main environmental factors that affect cotton's growth are the lowest temperature in the coldest month, the hottest month, the precipitation in the driest season, and the monthly average temperature difference. Further, the temperature factors contribute 71%, while the contribution ratio of terrain and soil factors is only 22%. The research shows that the current planting area is consistent with the predicted area in many areas of the study. Still, some areas, such as the Turpan region, northwest of Bayingolin Mongol Autonomous Prefecture, are supposed to be suitable for planting cotton, but it is not planted. The current potential distribution area of long-staple cotton is mainly located in Aksu Prefecture and the northern part of the Kashgar Prefecture region. The climatic prediction shows that the growing area of long-staple cotton may expand to southern Altay, central Aksu, and Bortala Mongol Autonomous Prefecture. This study will be helpful for cotton cultivation suitability areas in Xinjiang and other regions with similar environments.

Entrepreneurship education in South Africa holds significant promise in empowering the youth and fostering economic growth. This article explores the impact of entrepreneurship education on youth empowerment, focusing on case studies of successful young entrepreneurs, evaluation of entrepreneurial skills development, and analysis of employment and economic outcomes. While effective models of entrepreneurship education emphasize experiential learning and collaboration with local businesses, resource constraints and infrastructure gaps pose challenges. Moreover, socio-cultural perceptions and gender disparities influence youth's willingness to engage in entrepreneurship, hindering inclusivity. Evaluating the long-term impact remains challenging, requiring robust monitoring and evaluation mechanisms. The article concludes with recommendations to enhance the impact of entrepreneurship education, including increasing funding, challenging stereotypes, fostering collaboration, and developing evaluation mechanisms to support South Africa's youth in realizing their entrepreneurial potential.

Nitrate, cyanide, and flavonoids are among the chemicals that threatens hormones especially the thyroid gland and in turn affecting the body. Their presence in tobacco and cigarette shall be determine to inform the public. The objective of this work was to determine the extent of nitrate, cyanide, and flavonoids in soil and tobacco from Sokoto, Nigeria using standard methods. The results determined by this work indicated varied levels of goitrogens (cyanide, nitrate, and flavonoids) present in soils and tobacco leaves grown in three different points within Sokoto state, Nigeria (namely, Sokoto city, Gwadabawa, and Illela). 100.21±6.12 -705.10±4.60ppm, ppm 136± 6.10-170.30±3.36ppm, 7.10±0.3-17.0±0.11ppm are range values of cyanide, nitrate, and flavonoids respectively obtained in soils in Sokoto state. Likewise, 90.0±2.16-500.0±1.3ppm, 70.11±3.9-120.0±10.3ppm, 6.2±0.5-25.11±0.05ppm are the ranges of cyanide, nitrate, and flavonoids respectively determined in tobacco leaves in Sokoto state, Nigeria. There exist elevated levels of the goitrogens in soils and tobacco in Sokoto, therefore, risking the consumers and non-consumers to iodine deficiency. 
A Pure Mathematical Proof of the 4-Colour Theorem
Authors: Wang John
Published: August 2023

This work "A Pure Mathematical Proof of the 4-Colour Theorem" is related to the previous proof assited by computer. "Triangulations of Euler Convex Polygon" provides a fresh beginning point for the proof. The central concept is to discover an extended invariant property of Standard Graph’s boundary, which is described as "3-Colour All Phase States (3CP)" in this work and it is demonstrated that the standard graph’s boundary and sub-bound are 3CP and 4-colorable（4-3CP） via the expanded operation e(+, pi) and e(-, pi). It's exciting that this regularity was discovered for the first time and the 4-3CP invariant can naturally derive the 4-Colour Theorem. The majority of the definitions, theorems, and proof strategies are shown in this work.
Trajectory Tracking Control of Parking Automated Guided Vehicles using Nonlinear Disturbance Observer-based Sliding Mode

Published: August 2023

In order to improve the convenience of parking and increase parking density, automated valet parking systems based on parking AGVs (P-AGVs) are gradually becoming popular in cities. Parking AGVs can move toward any position and attain any orientation simultaneously with its Mecanum wheels, which makes it very convenient to transport vehicles in the parking lot. This paper proposes a nonlinear disturbance observer-based sliding mode controller for the trajectory tracking problem of a Parking AGV. First, a kinematics and dynamics models of a Parking AGV tracking trajectory are analyzed sequentially, and the influences of disturbing forces are considered. Afterwards, a nonlinear disturbance observer (NDO) is designed to estimate the disturbing forces and torques generated by castor wheels. Based on the designed NDO, a robust nonsingular terminal sliding mode (NTSM) controller is utilized to track reference trajectories. In addition, the stability of the NDO and NDO-NTSM control system is theoretically verified by using Lyapunov function. Finally, simulations and experiments are carried out to certify the effectiveness of the proposed control scheme. Experiment results show that the proposed NDO-NTSM controller can track the reference trajectories well and improve the trajectory tracking stability by 42–68% in comparison with a traditional NTSM controller.

Objective
Using bioinformatics to screen key prognostic genes for gastric cancer and exploring the immune infiltration relevance of these genes, providing new therapeutic targets for the diagnosis and treatment of gastric cancer.
Methods
Screening of differentially expressed genes based on TCGA and GEO databases, and performing GO and KEGG pathway enrichment analysis. Further selection of key prognostic genes for gastric cancer through COX regression and Lasso regression algorithms, and construction of a prognostic risk model. Drawing ROC curve and K-M survival curve to evaluate the prognostic value of genes. Analyzing the immune infiltration level of genes using CIBERSORT, ssGSEA algorithm, and TIMER database, and combining with HPA database to analyze the gene expression. Results: A total of 67 differentially expressed genes were screened out,the key prognostic gene AADAC in gastric cancer was identified, and a risk prognostic model was constructed. The ROC curve and AUC value indicate that the risk model has good predictive value. The K-M survival curve indicates that patients with high expression of AADAC have a worse survival outcome. The results of immune infiltration analysis suggest that the infiltration levels of activated B cells, CD56(dim) natural killer cells, central memory CD4 + T cells, central memory CD8 + T cells, eosinophils, immature B cells, macrophages, mast cells, monocytes, and helper T cells are positively correlated with the risk score. The expression of AADAC is weakly positively correlated with B cells, CD4 + T cells, and macrophages. Immunohistochemical results from the HPA database suggest that the staining intensity of AADAC in normal gastric mucosal tissues is weaker than that in gastric cancer tissues.
Conclusion
AADAC can effectively predict the prognosis of gastric cancer patients and is moderately correlated with the level of immune infiltration, providing a new direction for the diagnosis and immunotherapy of gastric cancer.
