Microbial Abundance of Waste Derived Biochar Incubated Acid Soil in Bangladesh
Authors: Rabbani Golam , Hossain Md. Faruque , Parveen Zakia
Published: March 2022

Due to climate change biochar is recently recommended as a control approach to increase crop productivity and global warming reduction. As biochar application changes the soil pH towards alkalinity, this effects acid soils nutrient cycles the same as microbial abundance. This research was conducted to investigate the microbial abundance as affected by waste-derived biochar application in two different rates on acidic soil of Bangladesh. Slow pyrolyzed (500±50ºC) different waste-derived biochars viz. sewage sludge, sugarcane bagasse, potato peels, water hyacinth, and organic waste were applied at 10 tons ha-1 and 15 tons ha-1 on the acidic soil. An in-vitro incubation study was conducted on experimental soil applying all the biochar to understand how nutrient availability and carbon dynamics affect the microbial abundance of the acid soil. The incubation study was divided into two stages: submerged condition (up to 60 days) followed by a dry condition (61 to 120 days) and biochars were applied in two different rates such as 10 and 15 tons ha-1. The viable count of bacteria significantly (P<0.05) increased with the variation of incubation periods and soil moisture content, although the rates did not make any difference. The beneficial Rhizobium spp. bacteria count ranged from 4.21 to 6.47 log CFU/g; Azotobacter spp. count ranged from 2.33 to 5.60 log CFU/g and Phosphate Solubilizing Bacterial count ranged from 2.30 to 3.74 log CFU/g. However, no sign of coliform bacteria or Escherichia coli was found in any sample, but also none of the biochar amended soil samples possessed Pseudomonas spp. and Trichoderma spp. In outcome, the waste-derived biochars treatments showed an insignificant impact on microbial parameters over the first 2 months after biochar incorporation which progressively increased with the course of time and the presence of oxygen.

Published: March 2022

Drone technology can provide a more cost-effective solution for many problems in different industries. This paper focuses on discussing how drones facilitate human life in various fields. They include infrastructure inspection, agriculture, medium and high-valued good delivery, geographical monitoring, rescue, and law enforcement. These areas were chosen because they can have the greatest impact if drones are used. Aerial unmanned vehicles can be used to map both horizontal surfaces and vertical structures. This can allow for a reduction in maintenance costs for buildings, cranes, wind turbines, speedways, and other infrastructures. It was found that the inspection cost for wind turbines could be reduced from 0.7% to 0.21% using drones. In terms of agriculture benefits, drones can use 800% less pesticide to provide the same protection benefits against plagues when compared to more conventional electric air-pressure knapsack sprayer (EAP) systems. Furthermore, it was determined that drones could save countless police officers' and civilians' lives by providing critical information in highly dangerous situations such as robberies, hostage cases, and car chases. The main obstacle that refrained from the widespread use of copter drones in these industries has been their limited flight time. Flight times of over two hours must be constantly achieved for the system to become cost-effective when compared to the traditional methods that are already in place.

The Role of Quality Human Capital and Planning Strategies in Achieving Event Sustainability in Lombok
Authors: Hizmi Surayyal , Rusdy Wijaya Satria
Published: March 2022

Background:

The success of implementing a sustainable event in a tourist destination cannot be separated from the influence of the quality of human resources (human capital) and planning strategies. However, studies of the interdependence between human capital and planning strategies in achieving successful implementation of sustainable events, especially on the island of Lombok, are still limited

Methodology:

This study aims to examine and analyze the extent to which aspects of human capital and strategic planning play a role in optimizing the implementation of events on the island of Lombok. The method used is a literature review from journals and trusted sources, as well as problem analysis through in-depth interviews with resource persons involved in the implementation of the event. The focus of this study is to compare tourism events, namely the Bali Arts Festival (PKB) in Bali and the Bau Nyale Festival in Lombok

Findings:

The results of in-depth interviews with several sources show that the PKB held on the island of Bali is still superior in the number of enthusiasts and concepts than the implementation of the Bau Nyale Festival on the island of Lombok. This is shown by the length of the PKB implementation and the age of the PKB which has been going on in the past 4 decades ago. In addition, the main factor that affects the sustainability of PKB is the quality of human resources in the tourism sector on the island of Bali, which is superior to the island of Lombok, so as to be able to formulate effective and creative planning in packaging the event. To achieve the sustainability of the event in Lombok, it is necessary to increase human capital and appropriate planning strategies through counselling, training, and the availability of Meeting study programs.

Conclusion:

Human capital and strategic planning play important roles for achieving sustainable event to support the development of tourist destination. The result of comparison study between Bali Arts Festival and Bau Nyale Festival shows that Bali Arts Festival was greater than Bau Nyale festival in terms of numbers of visitors and implementation concepts. This was proved by the length of festival and number of tourists visiting. Bali Arts Festival has been run for about 40 years, while Bau Nyale Festival has been currently occurred in Lombok. In addition, human capital in Bali Arts Festival was greater showing in how well management applied during the event, so that, it is able to plan with a precise strategy in achieving sustainable event.

Published: March 2022

Latar Belakang:

Digitalisasi penjualan melalui media website memfasilitasi promosi juga memiliki peluang yang sangat signifikan dalam memperluas pangsa pasar (Bernadi, 2013). Secara strategis, website dapat dijadikan sebagai pembeda yang dapat membentuk daya saing suatu perusahaan (Turban, King, & Lang, 2010). Konsumen (pelanggan) seringkali kesulitan mengakses berbagai informasi mengenai produk, informasi harga terkini, media promosi yang terbatas dan cenderung tidak fleksibel, hambatan personalisasi, dan biaya operasional yang meningkat (Meyliana, 2010).

Metode:

Jenis data yang digunakan dalam penelitian ini adalah data kuantitatif dan data kualitatif. Data kuantitatif adalah jenis data yang teratur atau mudah diukur, yang biasanya dinyatakan dalam satuan-satuan berupa angka. Sedangkan data kualitatif adalah data yang dinyatakan dalam bentuk kalimat, simbol, dan data lain yang bentuknya bukan dalam angka

Hasil:

Era digital dengan segala macam keunikan, kecanggihan dan kecepatanya memang sudah merasuki segala sisi kehidupan seseorang sehingga setiap orang tidak dapat menghindarinya, oleh karenanya setiap orang harus memahami apa maunya, manfaat dan tujuannya.

Considerações iniciais sobre a regulamentação de ruído para aeronaves eVTOL
Authors: Paul Stephan , Lorenzo Matheus de , Cordioli Júlio
Published: March 2022

A busca por novas soluções de mobilidade urbana deu origem a propostas de aeronaves elétricas de pequeno porte com capacidade de decolagem e pouso na vertical (eVTOL) para o transporte de passageiros e bens. Previstos para operarem em centros urbanos, estas aeronaves e suas operações precisam ser cuidadosamente regulamentadas em aspectos como segurança de voo e o impacto sonoro para garantir sua aceitação na comunidade. A considerável diferença entre aeronaves convencionais e suas operações em aeródromos e aeronaves eVTOL e suas operações no ambiente urbano é analisada apresentando-se algumas das principais características de 50 projetos de aeronaves eVTOL que possam ser de relevância na regulamentação destas aeronaves e suas operações. Para contextualização e comparação apresenta-se um breve resumo considerando aeronaves e aeródromos convencionais. A partir da análise de artigos científicos, whitepapers e documentos de natureza regulamentar, explana-se o estado atual da regulamentação de aeronaves eVTOL, dando ênfase nas questões que potencialmente tenham relevância para a regulamentação de ruído que ainda está em fase de desenvolvimento. Conclui-se que atualmente há poucos elementos base para uma regulamentação de ruído deste novo tipo de aeronaves e operações, mas que projetos de aeronaves e propostas de regulamentação parecem estar alinhados com critérios para regulamentação de helicópteros de pequeno porte e aeronaves com rotores basculantes. Contudo, basear-se extensivamente na regulamentação estas duas classes de aeronaves não parece ser a melhor estratégia a ser adotada pelas autoridades aeronáuticas competentes, pelas diferenças que existem no que concerne características das emissões sonoras e procedimentos de operação. Neste sentido os autores dão sugestões que possa nortear esforços de pesquisa para apoiar o processo de regulamentação.

Published: March 2022

Por diferentes circunstâncias e épocas do ano, o acesso à água por um sistema de captação subterrânea e superficial podem ser cessados, sujeitando a população local a recorrer a fontes não viáveis para sanar a escassez de água temporária. O presente estudo, que foi realizado de outubro de 2019 a março de 2020, tem como objetivo avaliar a possibilidade do uso de um destilador solar piramidal para produção de água e sua qualidade para consumo humano em situações emergenciais. O destilador solar piramidal foi construído com área de cobertura de vidro de 0,25 m², e operado com base em recomendações já conhecidas para maximizar sua produtividade, por meio da energia solar. As variáveis meteorológicas  radiação solar, temperatura ambiente, velocidade dos ventos e umidade relativa foram monitoradas para avaliar as potencialidades da eficiência de produção para características locais. Foram realizadas 67 coletas de produção de água destilada para evidenciar que o presente destilador solar foi capaz de produzir uma média de 3,22 L/m².dia e com 31% de eficiência. Também, foram realizadas 7 bateladas de análise da qualidade da água bruta e destilada, sendo que, dentro dos parâmetros analisados, a água destilada foi sempre considerada própria para consumo humano.
Sazonalidade da Radiação Solar Global em Superfície Vertical
Authors: Dal Pai Alexandre , Piacitelli Tieghi Camila
Published: March 2022

A radiação solar é fonte energética vital de todos processos existentes na Terra. Além disso, atualmente, com uma preocupação crescente em relação à utilização de fontes alternativas e sustentáveis de energia, seu uso tem sido utilizado como uma boa solução para conversão energética, controle de temperatura de água e conforto térmico. Em superfícies inclinadas, a orientação e o ângulo da inclinação da superfície alteram os níveis energéticos recebidos se comparados com uma superfície horizontal. Medidas da irradiação solar em superfícies verticais podem contribuir para planejamentos de instalações de painéis solares nas fachadas de construções, conforto térmico e iluminação natural.  Este trabalho teve como objetivo avaliar os dados da irradiação solar global em superfície vertical orientada ao Norte medidos durante o ano de 2010 na Faculdade de Ciências Agronômicas da UNESP de Botucatu. Foi comparada as medidas da radiação solar global em superfície vertical com superfície horizontal, a fim de se analisar os níveis quantitativos de irradiação solar global em superfície vertical no decorrer do ano para Botucatu–SP. Verificou-se também diferenças sazonais significativas entre as radiações solares global vertical e horizontal. Nos meses de verão, a irradiação medida na superfície vertical é composta basicamente das parcelas difusa e refletida. Para uso da irradiação solar durante o ano, recomenda-se a superfície vertical para os meses de maio a julho. Nos demais meses, recomenda-se a superfície horizontal.

Authors: Hughes G. , Bern H. , Chiang C-Y. , Goodall R. L. , Nunn A. J. , Rusen I. D. , Meredith S. K.
Published: March 2022

BACKGROUND: STREAM (Standardized Treatment Regimen of Anti-TB Drugs for Patients with MDR-TB) Stage 1 demonstrated non-inferior efficacy of a shortened regimen (the Short regimen) for rifampicin-resistant TB (RR-TB) compared to the contemporaneous WHO-recommended regimen. This
regimen included moxifloxacin and clofazimine, known to cause QT prolongation, and severe prolongation was more common on the Short regimen. Here we investigate risk factors for QT prolongation with the Short regimen.METHODS: Data from patients prescribed the Short regimen (n
= 282) were analysed to identify risk factors for severe QT prolongation (QT/QTcF ≥500 ms or ≥60 ms increase in QTcF from baseline).RESULTS: Of the 282 patients on the Short regimen, 94 (33.3%) developed severe QT prolongation: 31 QT/QTcF ≥500 ms; 92 experienced ≥60
ms QTcF increase from baseline. The median time to QT/QTcF ≥500 ms was 20 weeks (IQR 8–28), and the time to ≥60 ms increase from baseline was 18 weeks (IQR 8–28). Prolongation ≥500 ms was most frequent in patients from Mongolia (10/22, 45.5%) compared with 3.5–11.9%
at other sites, P < 0.001. Higher baseline QTcF increased risk of prolongation to ≥500 ms (QTcF ≥400 ms: OR 5.99, 95% CI 2.04–17.62).CONCLUSION: One third of patients on the Short regimen developed severe QT prolongation. QT/QTcF ≥500 ms was more common
in patients from Mongolia and in those with a higher baseline QTcF, which may have implications for implementation of treatment.

BACKGROUND: The presence of depressive symptoms in patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD) is an important research topic; however, the prevalence of depressive symptoms and the factors that influence their development are unclear.OBJECTIVE:
To analyse the association between CES-D (Center for Epidemiological Studies Depression Scale) scores and clinical parameters such as age, disease duration, pulmonary function, imaging findings, blood data, physical functions, sleep disturbances, respiratory symptoms and health-related quality
of life (HRQOL).METHODS: We conducted a cross-sectional retrospective study of 114 patients with NTM-PD at a single centre from March 2016 to January 2021 to evaluate the relationship between CES-D scores and clinical parameters.RESULTS: Participants had a median age
of 64 years; 32.5% of them had depressive symptoms. Disease duration, albumin, C-reactive protein, pulmonary function, dyspnoea, exercise capacity, respiratory symptoms, cough-related HRQOL and sleep disturbances were associated with depressive symptoms. Binomial logistic regression analyses
indicated that the CES-D score was significantly associated with cough-related HRQOL and sleep disturbances.CONCLUSION: A high percentage of NTM-PD patients in this study experienced depressive symptoms, and these patients had abnormalities of various clinical parameters. Cough-related
HRQOL and sleep disturbance had a strong influence on the development of depressive symptoms.

Published: March 2022

Die öffentliche und wissenschaftliche Auseinandersetzung nimmt seit einer Weile zunehmend Phänomene, die als Terrorismus, Radikalisierung und Extremismus bezeichnet werden, in den Fokus. Dabei wird insbesondere der Frage nachgegangen, wie diese Phänomene besser verstanden und wie schädliche Entwicklungen verhindert oder unterbrochen werden können. Ein besonderes Thema ist (Online-)Hate Speech und ihre mögliche Rolle als zu gewalttätigem Verhalten beitragender Faktor. Darüber hinaus wird oftmals das schädliche Potenzial abwertender Äußerungen und deren Auswirkungen auf Betroffene erörtert. Dieser Beitrag konzentriert sich auf (öffentliche) rechtsextremistische Online-Kommunikation, d.h. auf Sprechakte, die affirmative Elemente einer Ideologie der Ungleichwertigkeit enthalten oder zumindest auf Überzeugungen auf Seiten der sich Äußernden hindeuten. Die in diesem Beitrag vorgestellte Analyse konzentriert sich auf motivationsleitende Strukturen von Online-Hate Speech. Zentrales Ergebnis des qualitativen Ansatzes ist die Identifikation von drei Typen rechtsextremistischer Sprechakte in Online-Medien, die als ‚Propaganda‘, ‚Affektgeleitete Rede‘ und ‚Transgression‘ bezeichnet werden und jeweils durch spezifische Eigenheiten gekennzeichnet sind.
Variability and Relative Order of Susceptibility of Non-Enveloped Viruses to Chemical Inactivation
Authors: Steve Zhou Sifang
Published: March 2022

Viruses exhibit a marked variation in their susceptibilities to chemical and physical inactivation. Identifying a trend within these variations, if possible, could be valuable in the establishment of an effective and efficient infection control or risk mitigation strategy. It has been observed that non-enveloped viruses are generally less susceptible than enveloped viruses and that smaller sized viruses seem less susceptible than larger viruses. A theory of a “hierarchy” of pathogen susceptibility has been proposed and widely referenced. This concept provides a useful general guide for predicting the susceptibility of a newly emerged pathogen. It also serves as a theoretical basis for implementing a limited scale viral inactivation study that is to be extrapolated onto many other viruses. The hierarchy concept should be interpreted with caution since the actual viral inactivation efficacy may, in some cases, be different from the general prediction. The actual efficacy is dependent on the type of chemistry and application conditions. The order of susceptibility is not always fixed; and viruses within the same family or even the same genus may exhibit drastic differences. This chapter reviews viral inactivation data for several commonly used chemistries against non-enveloped viruses, highlighting the cases wherein the order of susceptibility varied or even flipped. Possible underlying mechanisms are also discussed.

In this chapter some preliminaries evaluation were outline briefly based on exploring the use of potential gravity field method in characterizing regional trends of Earth’s sequence system interms of gravitational potentials and fields, viz-a-viz., the background, instrumentation, theoretical model, gravity data reduction, geological framework, Bouguer reduction density, density acceptable models, free-air anomaly and interpretation of Bouguer gravity anomaly. Therefore, application of potential field method (gravity) explore these relationships by focusing on the formation and fill of a continental rift basin in characterizing regional trends of the Earth’s system interms of data processing, interpretation and Earth’s modelling. The study was carried out with the aim to understand and characterized the structural styles and regional trends of the Earth’s sequence beneath the Sokoto Basin and its surroundings. Results from the Bouguer gravity anomaly revealed gravity high of characteristic feature on the Bouguer map with a strong positive oval shape of causative bodies anomaly (> −14.0 mGal) having E-W trend. On contrary a number of gravity minima (−43.31 mGal) and maxima (−39.54 mGal) can be found ENE, N-W parts which are almost defining locations of deep basinal areas. The anomalous features shows negative as well as the lineaments pattern are virtually oriented in the NW-SE, ENE and E-W trends.
Il De incarnatione contra Apollinarium, libri duo. La teologia del De incarnatione Christi contra Apollinarium e del De salutari epiphania contra Apollinarium. Elementi di contatto e di divergenza
Authors: Gallorano Vincenzo ,   Instituto Patristico Augustinianum
Published: March 2022

Researchers agree on ascribing the De incarnatione Christi contra Apollinarium and the De salutari epiphania contra Apollinarium to two different authors, who probably shared the same theological education. The latter not only uses a mature theological style but shows a better knowledge of Apollinarius of Laodicea and his disciples’ writings. Even though the two authors try to demonstrate the presence of a perfect humanity in Christ, against Apollinarian thought, we can find some important differences in their works concerning the topic of the impeccabilitas of Christ and the relationship between sin and freedom. They explain in a different way the theory of salvation according to Apollinarius: while according to the author of De incarnatione Christi contra Apollinarium the man can save himself through the imitation of Christ, for the other writer salvation has been accomplished only because Christ is devoid of any trace of sin.
The Two Books of God
Authors: Juurikkala Oskari ,   Instituto Patristico Augustinianum
Published: March 2022

Augustine is considered one of the originators of the metaphor of the book of nature, but what did he say about it? This article examines all the metaphors with which Augustine seems to refer to the visible world as a divine book. It is found that four of the often-cited passages have a different meaning, but two of them refer to sensible nature as a book. The article further explores how the idea of God’s two books – nature and Scripture – influences Augustine’s literal interpretation of Genesis and his trinitarian theology. Finally, it argues that the ultimate foundation for the Augustinian book of nature should be sought in his theology of the Word.
Cystic Granulosa Cell Tumors of the Ovary: An Analysis of 80 Cases of an Often Diagnostically Challenging Entity
Authors: Boyraz Baris , Watkins Jaclyn C. , Soubeyran Isabelle , Bonhomme Benjamin , Croce Sabrina , Oliva Esther , Young Robert H.
Published: March 2022

Context.—

Granulosa cell tumors (GCTs) of both adult (AGCT) and juvenile (JGCT) types can rarely be completely or dominantly cystic, creating diagnostic difficulty because the cyst lining epithelium is often denuded.

Objective.—

To describe clinical, gross, microscopic, immunohistochemical, and molecular features of cystic GCTs with an emphasis on their differential diagnosis.

Design.—

We report 80 cystic GCTs (24 AGCTs and 56 JGCTs) in patients from ages 3 to 83 years (average ages, 35 years for AGCT and 22 years for JGCT).

Results.—

Nineteen of 43 patients with known clinical information (3 AGCT and 16 JGCT) had androgenic manifestations. All tumors were greater than 8 cm (average, 17 cm) with minimal to absent gross solid component. Denudation of cells lining the cysts was prominent. Invagination of the epithelium into the cyst walls was a key diagnostic feature, was present as cords, trabeculae, solid nests, and small and large follicles, and was identified in most tumors (17 AGCTs and 45 JGCTs). Cytologic atypia was essentially absent in AGCTs, whereas 14 JGCTs showed moderate to severe atypia of bizarre type. A theca cell component was present in all tumors and was extensive in 54. A FOXL2 hotspot mutation was identified in 1 of 4 AGCTs tested.

Conclusions.—

Despite extensive denudation, the finding of typical architectural patterns and cytologic features as well as, in some cases, androgenic manifestations helps differentiate cystic GCTs from follicle cysts, the most common and challenging differential diagnosis, as well as other cystic neoplasms that may enter the differential diagnosis. FOXL2 sequencing may show a false-negative result in cystic AGCT because of the limited number of cells present within the tumor sample.

Структура познатих историјских извора је таква да се о тим активностима може говорити тек фрагментарно и без могућности потпу- ног научног вредновања са временског, територијалног и квалитетног ас- пекта.

Васо Пелагић представља јединствену појаву у српској националној историји XIX вијека. Просвјетитељ и револуционар, писац и педагог, смио и необуздан, оставио је дубок траг у историји српског школ- ства. Богословија, отворена у Бањој Луци 1866. године уз помоћ кнеза Михајла Обреновића и Илије Гарашанина, представљала је оновремену најугледнију српску школу у Босни и Херцеговини. Двије године касније, у граду на Врбасу основана је и „Српска читаоница“. Школа се од почет- ка рада, због свог специфичног профила и наставног плана и програма, налазила под будним оком турских власти које су чекале згодну прилику да бунтовног Пелагића протјерају из покрајина. То је коначно остварено 1869. године.

Аустроугарска монархија од запосједања Босне и Херце- говине водила је политику противну интересима најбројнијег, српског на- рода, што је било видљиво и у области просвјете. Забрана српског имена у имену српских конфесионалних школа (до 1907. године) довела је до Цар- ских меморандума и борбе Срба за црквено-школску аутономију, те до покретања бројних националних друштава. У Босанској Градишци је тај замах био нарочито јак, јер је у граду још током турске управе постојала српска конфесионална школа и православна црква. Пред крај аустроугар- ске окупације Босанска Градишка је по броју школа заузимала осмо мје- сто у Босни и Херцеговини, а прво мјесто по броју националних друштава, због чега је понијела епитет „Мали Београд“.

As the lightest metal structural material, magnesium alloy is known as the “green engineering material” of the 21st century. Especially, crystalline-amorphous dual-phase nanostructure magnesium materials exhibit excellent mechanical properties, though the mechanism of interaction between the dislocation in crystal and amorphous phase is still under the investigation. In the present work, the interaction between the edge dislocation and amorphous phase in nanocrystalline magnesium under shear load is studied by using molecular dynamics simulation. The result indicates that the interaction mechanism between amorphous phase and dislocation shows the size dependence. Compared with the sample with smaller amorphous size, larger amorphous size will lead to a large second strengthening effect. And the mechanism of the interaction between amorphous phase and dislocation is mainly attributed to the pinning effect of amorphous on the dislocation. For the samples with small amorphous size, the pinning effect of amorphous on the dislocation is limited and the pinning time is shorter. The interaction mechanism is contributed mainly by the dislocation bypassing amorphous phase. While for the samples with larger amorphous size, the pinning effect of amorphous on the dislocation is larger and the pinning time is longer. The interaction is due mainly to the cross slip mechanism of dislocation caused by amorphous phase. The results from this work have a certain reference value and guiding significance for designing and preparing the high-performance magnesium and its alloys.

Background

Bronchoalveolar lavage fluid (BALF) exosomes possess different properties in different diseases, which are mediated through microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), among others. By sequencing the differentially expressed lncRNAs in BALF exosomes, we seek potential targets for the diagnosis and treatment of acute lung injury (ALI).

Methods

Considering that human and rat genes are about 80% similar, ALI was induced using lipopolysaccharide in six male Wistar rats, with six rats as control (all weighing 200 ± 20 g and aged 6–8 weeks). BALF exosomes were obtained 24 h after ALI. The exosomes in BALF were extracted by ultracentrifugation. The differential expression of BALF exosomal lncRNAs in BALF was analyzed by RNA sequencing. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to predict the functions of differentially expressed lncRNAs, which were confirmed by reverse transcription–polymerase chain reaction.

Results

Compared with the control group, the ALI group displayed a higher wet/dry ratio, tumor necrosis factor-α levels, and interleukin-6 levels (all P < 0.001). The airway injection of exosomes in rats led to significant infiltration by neutrophils. A total of 2,958 differentially expressed exosomal lncRNAs were identified, including 2,524 upregulated and 434 downregulated ones. Five lncRNAs confirmed the reliability of the sequencing data. The top three GO functions were phagocytic vesicle membrane, regulation of receptor biosynthesis process, and I-SMAD binding. Salmonella infection, Toll-like receptor signaling pathway, and osteoclast differentiation were the most enriched KEGG pathways. The lncRNA–miRNA interaction network of the five confirmed lncRNAs could be predicted using miRDB.

Conclusions

BALF-derived exosomes play an important role in ALI development and help identify potential therapeutic targets related to ALI.
Bioinformatical analysis identifies PDLIM3 as a potential biomarker associated with immune infiltration in patients with endometriosis
Authors: Gan Lei , Sun Jiani , Sun Jing
Published: March 2022

Background

Endometriosis is a chronic systemic disease, whose classic symptoms are pelvic pain and infertility. This disease seriously reduces the life quality of patients. The pathogenesis, recognition and treatment of endometriosis is still unclear, and cannot be over emphasized. The aim of our study was to investigate the potential biomarker of endometriosis for the mechanism and treatment.

Methods

Using GSE11691, GSE23339 and GSE5108 datasets, differentially expressed genes (DEGs) were identified between endometriosis and normal samples. The functions of DEGs were reflected by the analysis of gene ontology (GO), pathway enrichment and gene set enrichment analysis (GSEA). The LASSO regression model was performed to identify candidate biomarkers. The receiver operating characteristic curve (ROC) was used to evaluate discriminatory ability of candidate biomarkers. The predictive value of the markers in endometriosis were further validated in the GSE120103 dataset. Then, the expression level of biomarkers was detected by qRT-PCR and Western blot. Finally, the relationship between candidate biomarker expression and immune infiltration was estimated using CIBERSORT.

Results

A total of 42 genes were identified, which were mainly involved in cytokine–cytokine receptor interaction, systemic lupus erythematosus and chemokine signaling pathway. We confirmed PDLIM3 was a specific biomarker in endometriosis (AUC = 0.955) and validated in the GSE120103 dataset (AUC = 0.836). The mRNA and protein expression level of PDLIM3 in endometriosis tissue was significantly higher than normal. Immune cell infiltration analysis revealed that PDLIM3 was correlated with M2 macrophages, neutrophils, CD4+ memory resting T cells, gamma delta T cells, M1 Macrophages, resting mast cells, follicular helper T cells, activated NK cells, CD8+ T cells, regulatory T cells (Tregs), naive B cells, plasma cells and resting NK cells.

The transportation infrastructure is one of the most important resources for a country's economic and social well-being. The effectiveness of a country's street network will decide whether it develops further or stagnates. With the increasing number of vehicles on the road and the effects of urbanization, traffic roads are being subjected to a variety of requests and uses for which they were not designed, sized, or predicted. Because of the critical relevance of traffic roads, research must begin to lessen the effects of traffic jams in the streets, determine the appropriate number of traffic lanes, and integrate real-time traffic information into GPS systems. The goal of modeling a traffic-road system is to either build new traffic systems or gain a better knowledge of existing traffic systems so that they can be optimized. The accuracy, performance, stochastic and dynamic behavior of the model produced will be evaluated using a simulation of a genuine traffic system. This paper provides microscopic models based on cellular automation to replicate the behavior of various automobiles on a set of urban streets in Cluj Napoca city downtown. This model includes streets with multiple traffic lanes, various types of vehicles such as automobiles, buses, and trams, intersections with multiple possible upcoming streets controlled by traffic lights, bus stops inside and outside the traffic lane, tram stops inside the traffic lane, pedestrian crosswalks, and parking areas alongside and transversely with the right traffic lane of a street. TCA (Traffic Cellular Automata) is a proposed model that produces adequate findings in urban traffic theory. The results were obtained in both free-flow and traffic-jam conditions.

The paper presents results obtained by SiC ceramic implementation for slide burnishing. Analyzes of the effect of the burnishing force and feed on selected surface texture parameters were conducted. The influence of technological parameters was assessed according to the analysis of variance. The burnishing force and feed affected most of the examined surface texture parameters in the analyzed ranges. Optimal values were found for the technological parameters. In most cases, the minimum of height parameters were achieved for 80 N of burnishing force and 0,063 mm/rev of feed. Limitations in the increase in the burnishing force were also found.

Today, manufacturing companies strive to find the stability between satisfying their customers by producing in accordance with their expectations (quantity and quality) and keeping leading positions when it comes to competitiveness on their markets. This paper aims to compare two very well-known philosophies in the manufacturing industry: Lean Manufacturing (LM) and Six Sigma (6S). The integration of these two philosophies solves the insufficiency that the absence of one of them causes, considering that Six Sigma is based on statistical tools that focus on measuring and reducing variations in processes and achieving goals set by the customers' requirements. Lean Manufacturing focuses mainly on the value added for a client, for example,by eliminating all kinds of waste from processes what leads to the reduction of time and cost of the process. Lean Six Sigma combines the features of both methods, which means that it meets the client's requirements based on statistical knowledge and the process flow control, but simultaneously in addition to that, it reduces the time and cost of the processes. As a result, it gives manufacturing companies the possibility of having loyal and satisfied customers and who provide companies with new customers. This paper has a greater goal of persuading the Angolan manufacturing industries to implement the Integrated Lean Six Sigma (IL6S) into their production and management processes.
