Modeling the Seasonal Variation of Windborne Transmission of Porcine Reproductive and Respiratory Syndrome Virus between Swine Farms
Authors: Lim Seunghyun , Perez Andres M. , Kanankege Kaushi S. T.
Published: August 2023

Modeling the windborne transmission of aerosolized pathogens is challenging. We adapted an atmospheric dispersion model named the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model to simulate the windborne dispersion of porcine reproductive and respiratory syndrome virus (PRRSv) between swine farms and incorporated the findings into an outbreak investigation. The risk was estimated semi-quantitatively based on the cumulative daily deposition of windborne particles and the distance to the closest emitting farm with an ongoing outbreak. Five years of data (2014:2018) were used to study the seasonal differences of the deposition thresholds of the airborne particles containing PRRSv and to evaluate the model in relation to risk prediction and barn air filtration. When the 14-day cumulative deposition was considered, in winter, above-threshold particle depositions would reach up to 30 km from emitting farms with 84% of them being within 10 km. Long-distance pathogen transmission was highest in winter and fall, lower in spring, and least in summer. The model successfully replicated the observed seasonality of PRRSv, where fall and winter posed a higher risk for outbreaks. Reaching the humidity and temperature thresholds tolerated by the virus in spring and summer reduced the survival and infectivity of aerosols beyond 10–20 km. Within the data limitations of voluntary participation, when wind was assumed to be the sole route of PRRSv transmission, the predictive performance of the model was fair with >0.64 AUC. Barn air filtration was associated with fewer outbreaks, particularly when exposed to high levels of viral particles. This study confirms the usefulness of the HYSPLIT model as a tool when determining seasonal effects and distances and informs the near real-time risk of windborne PRRSv transmission that can be useful in future outbreak investigations and for implementing timely control measures.

Published: August 2023

The Gully Consolidation and Highland Protection (GCHP) project is an important governance measure for controlling source erosion and reducing soil erosion in the Loess Plateau, which has been explored and developed continuously in recent decades. However, there is no international precedent for research on the implementation effect of the GCHP project, and it is still relatively weak. In order to quantify the erosion of a small watershed under the construction of a gully head landfill, this study selected Yangjiagou (YJG) as the research area. The spatial analysis function of ArcGIS was used to process DEM and soil type data, the GeoWEPP model was used to simulate soil erosion, and the changes of runoff and sediment yield before and after gully head landfill were analyzed. The results showed that compared with the simulated original soil erosion amount, the annual runoff decreased by 13.13%, and the sediment yield decreased by 37.61% after gully head landfill, indicating that the GCHP project positively influenced soil erosion control. After the gully head landfill measures are taken, the flow path becomes shorter, so the flow scour capacity is weakened. Soil and water control is very effective in the short term, but if long-term maintenance is not carried out, the intensity of soil and water loss is likely to be aggravated. This study provides an effective verification method for the feasibility of a soil loss control scheme on the Loess Plateau and provides a reference for promoting ecological priority and efficient management in the Loess gully area. Ultimately, it will serve the ecological protection and high-quality development of the Yellow River Basin.

Published: August 2023

The present work shows the obtainment of biosynthesized SiO2 with the aid of Jasminum grandiflorum plant extract and the study of its photocatalytic ability in dye degradation and antibacterial activity. The obtained biosynthesized SiO2 nanoparticles were characterized using X-ray diffractometer analysis, Fourier transform infrared spectroscopy analysis, ultraviolet–visible diffuse reflectance spectroscopy, field-emission scanning electron microscope with energy-dispersive X-ray analysis, transmission electron microscopy and X-ray photoelectron spectroscopy. The UV-light irradiated photocatalytic activity of the biosynthesized SiO2 nanoparticles was examined using methylene blue dye solution. Its reusability efficiency was determined over 20 cycles and compared with the commercial P-25 titanium dioxide. The bacterial resistivity of the biosynthesized SiO2 nanoparticles was examined using S. aureus and E. coli. The biosynthesized SiO2 nanoparticles showed a high level of crystallinity with no impurities, and they had an optimum crystallite size of 23 nm, a bandgap of 4 eV, no Si-OH groups and quasi-spherical shapes with Si-2p at 104 eV and O-1s at 533 eV. Their photocatalytic activity on methylene blue dye solution could reach 90% degradation after 40 min of UV light exposure, and their reusability efficiency was only 4% less than that of commercial P-25 titanium dioxide. At the concentration of 100 μg/mL, the biosynthesized SiO2 nanoparticles could allow the resistivity of E. coli to become borderline to the resistant range of an antibiotic called Amikacin.

Published: August 2023

Rainfall forecasting is one of the most challenging factors of weather forecasting all over the planet. Due to climate change, Thailand has experienced extreme weather events, including prolonged lacks of and heavy rainfall. Accurate rainfall forecasting is crucial for Thailand’s agricultural sector. Agriculture depends on rainfall water, which is important for water resources, adversity management, and overall socio-economic development. Artificial intelligence techniques (AITs) have shown remarkable precision in rainfall forecasting in the past two decades. AITs may accurately forecast rainfall by identifying hidden patterns from past weather data features. This research investigates and reviews the most recent AITs focused on advanced machine learning (ML), artificial neural networks (ANNs), and deep learning (DL) utilized for rainfall forecasting. For this investigation, academic articles from credible online search libraries published between 2000 and 2022 are analyzed. The authors focus on Thailand and the worldwide applications of AITs for rainfall forecasting and determine the best methods for Thailand. This will assist academics in analyzing the most recent work on rainfall forecasting, with a particular emphasis on AITs, but it will also serve as a benchmark for future comparisons. The investigation concludes that hybrid models combining ANNs with wavelet transformation and bootstrapping can improve the current accuracy of rainfall forecasting in Thailand.

Published: August 2023

Conducting excellent thermal management of a new electric vehicle motor drive system may enhance the operational efficiency of the motor drive and minimize its pollutant emissions and energy losses. As an important part of the motor thermal management system, it is necessary to improve the design of the drive motor for the fan. This paper presents the design of a 12s-10p permanent magnet brushless DC motor with a rated speed of 2200 rpm and a rated voltage of 12 V based on finite element analysis. At this rated speed, the maximum torque the motor can output is 1.80 N·m. Then, we calculated the loading capacity of the motor by parameterizing the resistance in the circuit. We have built a prototype based on the design results and built a test bench to test the loading capacity of the prototype. A comparison revealed that the error between the experimental and calculated results was small. Accordingly, it is believed that this work is capable of serving as a theoretical guide for the design and manufacture of automotive cooling fans in the future.

Authors: Hou Zhenhua , Wang Qigan , Si Tengfei , Zhang Shiqiang
Published: August 2023

Noise of internal combustion engine is the main source of noise pollution, and mufflers are the main means to reduce exhaust noise of internal combustion engine. In the process of improving the acoustic performance of the exhaust muffler based on the three-dimensional numerical method,
the influence of the high speed and high temperature airflow discharged by the engine in the actual working process on the acoustic performance of the exhaust muffler is often ignored, which leads to the obvious deviation between the predicted results and the actual situation. In this paper,
based on the structural optimization design of the straight-through perforated pipe resistance muffler, the noise characteristics of the straight-through perforated pipe resistance muffler with perforated corrugated lining was analyzed considering the airflow velocity and temperature inside
the muffler. The influence of temperature and velocity fields on the acoustic performance of muffler was studied by using numerical simulation method, which takes the solution results inside muffler as boundary conditions of sound field analysis. The influence of changing the internal structure
of muffler on the aerodynamic performance of muffler was discussed, and the pressure loss is analyzed. The research has shown that adding perforated corrugated lining inside muffler could effectively improve the transmission loss of muffler and the noise reduction performance of prototype
straight-through perforated pipe-resistant muffler.
Case study: Acoustic radiation characteristics and mechanism of high-speed railway box-girder bridge
Authors: Zhang Xiaoan , Yang Jianjin
Published: August 2023

The proportion of box-girder bridges in high-speed railways in China is high. The noise caused by trains passing a box-girder bridge is more intense than the noise in other sections of the railway because it is radiated by the bridge. This study investigates the acoustic radiation characteristics
and mechanism of the box-girder bridge including low-frequency vibrations below the hearing threshold. The foregoing is examined in terms of natural vibration characteristics, vibration responses of the bridge under nonlinear train–track dynamic interactions, and structural noise radiation
principle. The results show that the structural resonance, acoustic radiation efficiency, acoustic–vibration coupling in the bridge cavity, and severe train-induced vibrations play important roles in the acoustic radiation of the box-girder bridge. Under moving train loads, bridge vibrations
are mainly in the 80- to 100-Hz frequency range and cause distinct noise radiation. Moreover, the low-frequency (20 Hz) train-induced vibrations of the bridge can generate distinct low-frequency noise. Additionally, the box-girder bridge cavity induces acoustic–vibration coupling, which
can aggravate the noise radiation on both sides of the box-girder bridge.

Published: August 2023

En 1950, Oswald Menghin y Marcelo Bórmida publican en la revista Runa los resultados de sus primeras investigaciones en la región pampeana, en la Gruta del Oro en el sistema serrano de Tandilia. En base a muy pocos artefactos líticos y haciendo correlaciones paleoclímaticas a larga distancia propusieron para la región la existencia hacia el 5000 a. C. de un complejo cultural epiprotolítco de cazadores inferiores al que llamaron Tandilense. Este trabajo dio origen a toda una serie de investigaciones arqueológicas en la región fuertemente alineadas con el paradigma histórico-cultural austro alemán. El artículo fue la piedra basal de una corriente teórica que dominaría la Arqueología pampeana durante los siguientes treinta años. En este ensayo se resumen y discuten los hallazgos y las interpretaciones de Menghin y Bórmida sobre los materiales de la Gruta del Oro y se analiza el contexto teórico y político para explicar por qué, el modelo propuesto por Menghin y Bórmida fue dominante hasta la década de 1980.

Are Youtube Videos About Ultrasound-Guided Breast Biopsy Useful and Reliable?
Authors: KONUKOĞLU Osman , KAYA Veysel , TAHTABAŞI Mehmet
Published: August 2023

Background: The aim of this study is to evaluate the usefulness and quality of YouTube videos on ultrasound-guided breast biopsy (UGBB) for patients.
Materials and Methods: A video search was undertaken on YouTube on Aug 14, 2020 using the keywords, ‘breast biopsy’, ‘ultrasound-guided core biopsy’, ‘breast ultrasound’, and ‘breast biopsy ultrasound’. Top 100 videos were selected using each keyword (total 400 videos). After applying the exclusion criteria, 51 videos were evaluated by two researchers based on the patient information form of the American Cancer Society and American College of Radiology. According to these criteria, the videos were divided into four categories as very useful, useful, slightly useful, and not useful. Video parameters were compared between the groups by the Kruskal–Wallis test.
Results: Of the 51 videos analyzed, 13.7% (n=7) were very useful, and 41.2% (n=21) were useful. Of the very useful videos, 85.7% (n=6) had been uploaded by physicians/hospitals. The DISCERN reliability score was significantly higher in very useful videos (median: 4, range: 2-5, p < 0.001). The length and number of likes and comments were significantly higher for the videos uploaded by civilian individuals (p=0.005, p=0.046, and p=0.013, respectively). Not useful and very useful videos were significantly longer (p = 0.01)
Conclusion: Although the primary sources of high-quality and very useful YouTube videos about UGBB were physicians/hospital, a significant portion of low-quality videos had also been uploaded by this group. Thus, medical professionals should take care to upload well-informed videos.
The Efficacy of Using Intraoperative Ultrasound and Frozen Pathology in Breast Conserving Surgery on Safe Surgical Boundary
Authors: TÜZÜN Abidin , DALBAŞI Erkan , GEDİK Ercan
Published: August 2023

Background: Breast cancer is the most common cancer in women over the age of 40. The lifetime risk is around 12%. Today, breast cancer patients are diagnosed at an early stage thanks to screening programs, and thus mortality has decreased to around 25-30%. The positivity or closeness of surgical margins in breast conserving surgery varies between 5-60%. Negativity of surgical margins is very important to prevent future recurrent breast cancer, to pre-vent recurrent surgeries, and to prevent additional treatments. In this study, we aimed to investigate the efficacy of intraoperative ultrasonography and frozen section use in breast cancers treated with breast conserving surgery in obtaining safe surgical margins and in postoperative cosmetic terms.
Materials and Methods: This study includes 150 patients diagnosed with breast cancer and treated with breast con-serving surgery in between January 2015 and January 2019. The presence of distant metastases and multifocal or centrally located tumor involvement in the breasts were investigated. The localization of the tumor was marked anatomically by preoperative ultrasonography in all patients. The operation was started 15 minutes after the injec-tion. The tumor was completely excised, leaving at least 1 cm of intact tissue around the tumor, including the skin, on the preoperatively marked area, including the underlying muscle fascia. Medial and superior borders were marked with string. This excised tissue block was examined with intraoperative ultrasonography.
Results: The mean age of the patients was 48,3± 9.7 years. While the tumor was located in the right breast in 83 (55.3%) of the patients, it was located in the left breast in 67 (44.7%) patients. The tumor was located in the upper outer quadrant in 67 (44.7%) patients, in the upper inner quadrant in 53 (35.3%) patients, and in the lower outer quadrant in 30 (20%) patients. Axillary dissection was performed in 21 (14 %) of the patients because sentinel lymph node was positive. In histological typing, 141 (94 %) patients were ductal carcinoma and 9 (6 %) patients were lobular carcinoma.
Conclusions: As a result of our study and literature review, we think that frozen examination together with intraope-rative ultrasonography is a simple, easily applicable and cosmetically good method to determine the safe surgical margin in breast conserving surgery.

Nesse encontro, Exú quis louvar seus hábitos performáticos carnais e libidinosos, rompendo normas, promovendo mudanças e apresentando as contradições de ser em si uma antidefinição que se transforma a cada manhã rumo ao infinito. Esta série de seis fotos-performances foi criada a partir da Prática como Pesquisa (PaR), utilizando-se da improvisação para composição nas urbanidades, objeto de minha pesquisa de mestrado no PPGAV da UFBA. As imagens são oriundas de uma performance comissionada para o Documentário “Testemunho de Bichas Pretas” (2022).

Abstract: Osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage degeneration, subchondral bone changes, osteophyte formation, sinovitis or arthritis. The aim of osteoarthritis management is to reduce pain, increase joint function, and decrease disability. Hyperbaric oxygen therapy (HBOT) can inhibit astrocyte activation and inflammatory factor production, and maintain transmission and intergration of sensoric information through dorsal neurons, therefore, resulting in pain reduction. This study aimed to evaluate the effectiveness of HBOT in chronic pain of knee osteoarthritis. This was a parallel, two-arm, placebo-controlled, randomized clinical trial in adults with knee osteoarthritis at two hospitals in Manado, namely Badan Layanan Umum Rumah Sakit Umum Pusat Prof. Dr. R. D. Kandou and Rumah Sakit Siloam. The results obtained 44 patients suffered from knee osteoarthritis grade 1 dan 2 associated with chronic pain as subjects, divided into two groups namely intervention with HBOT and control groups. Determination of normality of numeric variables was performed with Shapiro-Wilk test. The statistic test confirmed that the distribution of VAS scores was relatively not different between before and after HBOT, and the control group (p=0.421 and p=0.634). In conclusion, hyperbaric oxygen therapy can be used to reduce chronic pain in knee osteoarthritis.

Abstrak: Osteoartritis (OA) merupakan suatu penyakit sendi degeneratif yang dikarakteristikkan dengan degenerasi kartilago progresif, perubahan tulang subkondral, pembentukan osteofit, dan sinovitis atau inflamasi sendi. Tujuan penatalaksanaan OA ialah untuk meredakan nyeri, meningkatkan fungsi, dan membatasi disabilitas Terapi oksigen hiperbarik (TOHB) dapat menginhibisi aktivasi astrosit dan produksi faktor inflamatorik serta mempertahankan transmisi dan integrasi informasi sensori melalui neuron dorsal sehingga nyeri menurun. Penelitian ini bertujuan untuk menilai efektifitas TOHB dalam penatalaksanaan nyeri kronik pada OA lutut. Penelitian ini didesain sebagai suatu parallel, two-arm, placebo-controlled, randomized clinical trial pada dewasa dengan OA lutut di dua rumah sakit di Manado, Badan Layanan Umum Rumah Sakit Umum Pusat Prof. Dr. R. D. Kandou dan Rumah Sakit Siloam. Sebanyak 44 pasien OA lutut grade 1 dan 2 dengan nyeri kronik menjadi subjek penelitian, yang dibagi secara acak atas dua kelompok: intervensi TOHB dan kontrol. Penentuan normalitas variabel numerik dilakukan menggunakan uji Shapiro-Wilk. Hasil statistik mengonfirmasi distribusi penurunan skor VAS relatif tidak berbeda bermakna sebelum dan setelah TOHB dan kelompok kontrol (p=0,421 dan p=0,634). Simpulan penelitian ini terapi oksigen hiperbarik kemungkinan dapat menurunkan nyeri kronik pada penderita osteoartristis lutut.

The Status of Semantics in Transformational Generative Grammar
Authors: Abdul Jalil Jassim Hejal
Published: August 2023

Meaning is one of the problems which seems difficult to deal with to

such extent that Leonard Bloomfield, who resisted the mentalist approach

to language, considered it impossible to define meaning till we have a

scientifically accurate knowledge of everything in the speaker’s world.

Linguists consider meaning as one of the most complex subjects to deal

with and some of them are in doubt whether meaning can be studied

objectively and systematically as phonology and grammar or not. The

complexity and vagueness of semantics are due to the fact that semantics

is not concerned with one specific field but with various fields such as:

philosophy, logic, psychology, anthropology, and sociology. Many

linguists, recently, do their new theory of grammar.

This paper is intended to present a brief study of the status of semantics in

Transformational generative grammar. It is of three parts:

 

Part One is concerned with the scope of semantics.

Part Two presents a historical survey of semantics and its

 

historical development in the schools of grammar.

Part Three is a review of the status of semantics in the

 

Transformational schools of grammar.
Verificación clínica de REALQUALITY RQ-HPV HR Multiplex de acuerdo a guías internacionales para la detección del virus del papiloma humano

La verificación de una prueba molecular antes de su uso en la práctica clínica es esencial para brindar un servicio seguro y útil tanto a médicos como a pacientes, por lo que es responsabilidad de cada laboratorio determinar y documentar que las afirmaciones del ensayo sean precisas, reproducibles y sólidas. Aunque existen pautas sobre cómo se pueden abordar los estudios de validación y verificación para los ensayos moleculares, en Colombia rara vez se publican los detalles específicos del enfoque utilizado por los laboratorios. Este artículo describe los principios de verificación de una prueba de biología molecular, dada la importancia de que una verificación bien diseñada definirá las características de rendimiento del ensayo y los posibles resultados generados por este. El kit de diagnóstico REALQUALITY RQ-HPV HR Multiplex es una PCR multiplex en tiempo real para la detección y genotipado simultáneo de 14 genotipos de VPH de alto riesgo (HR), incluidos VPH -16 y VPH-18. Antes de su implementación en el laboratorio realizamos un proceso de verificación del método, con la finalidad de confirmar que las características de rendimiento del ensayo en el laboratorio clínico sean las indicadas por el fabricante. Utilizando como guía la norma CLSI MM-19 nosotros encontramos una alta sensibilidad y especificidad de este método.
CYTOPATHOLOGICAL EVALUATION OF METASTATIC LYMPHADENOPATHIES- A RETROSPECTIVE AND PROSPECTIVE STUDY

Background: The diagnosis of lesions and masses at diverse sites and organs can be made with help of ne needle aspiration cytology, which is
safe, easy to use, affordable, well-tolerated, and widely accepted. FNAC is a valuable outpatient treatment that is relatively painless, convenient for
patients and doctors alike, avoids physical and psychological damage that might occasionally follow an open surgical biopsy, and offers strong
correlation between cytology and histopathology. The major goal of this study is to provide the most comprehensive picture of the present situation
of lymph node metastatic lesions and to provide information on early detection, treatment, and prognosis. Method: All metastatic lymph node
lesions were reported to Govt. Medical College Surat, Department of Pathology between June 2018 and June 2020 was subject of this retrospective
and prospective study. Results: A total of 3091 cases of ne needle aspiration cytology were performed, 1514 cases involved supercial lymph
node FNACs, out of which 200 cases had metastatic lymph node lesions. Squamous cell carcinoma from cervical lymph nodes was most prevalent
metastatic lesion. Males made up the majority of cases of metastatic tumors, which occurred most frequently in patients aged 51 to 60 years.
Histopathological conrmation was performed in 71 out of 200 cases, and FNAC's diagnostic efcacy was 100%. Conclusion: Cytological
evaluation along with proper clinic-radiological correlation is quite useful in diagnosing metastasis with good degree of certainty.
