Mote Cyclone Robber System PM10 Emission Factors and Rates for Cotton Gins: Method 201A PM10 Sizing Cyclones
Authors: Boykin Clif , Buser Michael , Whitelock Derek , Holt Gregory
Published: June 2024

This report is part of a project to characterize cotton gin emissions from the standpoint of stack sampling. The impetus behind this project was the urgent need to collect cotton gin emissions data to address current regulatory issues. A key component of this study was focused on EPA emission factors for particulate matter with a particle diameter nominally less than or equal to 10 µm (PM10). The 1996 EPA AP-42 emission factors were assigned quality ratings, from A (Excellent) to E (Poor), to assess the quality of the data being referenced. Emission factor quality ratings for cotton gins were extremely low. Also, some commonly used cotton gin systems were not represented or were combined with another system under a single emission factor in AP-42. There were no 1996 EPA AP-42 emission factors published for mote cyclone robber systems. The objective of this study was to collect PM10 emission factor data for mote cyclone robber systems at cotton gins located in regions across the cotton belt based on EPA-approved stack sampling methodology, Method 201A. The project plan included sampling seven cotton gins across the cotton belt. Key factors for selecting specific cotton gins included: 1) facility location, 2) production capacity, 3) processing systems, and 4) abatement technologies. Three of the seven gins had mote cyclone robber systems. In terms of capacity, the three gins were typical of the industry, averaging 28.0 bales/h during testing. Some test runs were excluded from the test averages because they failed to meet EPA Method 201A test criteria. Also, other test runs, included in the analyses, had cotton lint fibers that collected in the ≤ 10 µm samples. This larger lint material can affect the reported emissions data, but EPA Method 201A does not suggest methods to account for these anomalies. The mote cyclone robber system average emission factors for PM10 and total particulate were 0.028 kg/227-kg bale (0.061 lb/500-lb bale) and 0.039 kg/bale (0.087 lb/bale), respectively. The mote cyclone robber system PM10 emission rate test averages ranged from 0.36 to 1.71 kg/h (0.79-3.77 lb/h). The ratio of mote cyclone robber system PM10 to total particulate was 70.5%.
RANCANG BANGUN SUCTION PUMP DENGAN 2 TABUNG DAN PENGATURAN TEKANAN BERBASIS PWM ARDUINO
Authors: Kusi Olla Patrisius , Wahyudi Bayu , Ningtias Diah Rahayu
Published: June 2024

Suction is used in the medical field to take or drain fluids out of the body. Professional use of suction can be used to remove or reduce blood in the operated area to allow the surgeon to see and work on that area. Suction is also used to remove blood that is already in the skull after intracranial bleeding. Most of the suction devices used still have a simple appearance or still have a manometer, which means that the suction pressure on the suction cannot be adjusted automatically. Therefore, the aim of this research is to design a suction pump with motor speed using PWM (Pulse Width Modulation). The method for making this tool uses an Atmega328 microcontroller as a controller, an LCD (Liquid Crystal Display) as a display of pump suction speed and suction pressure, an MPX5500DP sensor as a suction pressure reader. To control the suction speed, the L298N motor driver uses a PWM (Pulse Width Modulation) signal with a maximum result of -178 mmHg. Testing was carried out at vacuum pressure using a DPM (Digital Pressure Meter), apart from that testing was also carried out on the circuit working system. Circuit testing is needed to find out the working principle of the circuit and the tools being made. After testing and measuring the tool, the error percentage was 0.86% for the smallest result. Meanwhile, the largest error percentage is 8.5%. The allowable correction value for the suction pump pressure parameter is ± 10% of the maximum scale of the tool setting point. So from the results of this analysis the tool is suitable for use because it is still within safe tolerance limits.
DESAIN ANTENA MONOPOLE WIDEBAND UNTUK PERALATAN VHF A/G
Authors: Tegsadama Aryo Tegsadama , Wildan Muh , Wahyudi Johan
Published: June 2024

VHF-A/G is a radio communication device operating in the frequency range of 117.975 MHz - 137 MHz. This device is utilized as a means of communication between Air Traffic Control officers at an Air Traffic Service (ATS) unit and pilots in aircraft. The VHF-A/G equipment is required to be placed inside the Control Tower, with the VHF-A/G antenna mandated to be positioned atop the Control Tower. Typically, antennas used are narrowband antennas, effective only in receiving or transmitting signals within specific frequencies. If one wishes to use such an antenna on other frequencies, adjustments (matching) are required. Hence, the author has conceptualized designing an antenna capable of operating across various frequencies within the VHF A/G frequency range. In the design process, electromagnetic simulations using CST Studio 2021 allow for in-depth analysis of antenna characteristics, including impedance, radiation efficiency, and radiation patterns. It is hoped that simulation results demonstrate that the resulting antenna can achieve performance meeting VHF A/G requirements, producing consistent radiation patterns and high efficiency across the targeted frequency range.

Ung thư phổi là nguyên nhân phổ biến nhất gây tử vong liên quan đến ung thư trên toàn cầu. Khoảng một nửa số bệnh nhân (BN) ung thư phổi khi được phát hiện đã có di căn xa, các vị trí di căn thường gặp là hạch bạch huyết, gan, xương, não và tuyến thượng thận. Di căn đường tiêu hóa từ ung thư phổi nguyên phát rất hiếm gặp, đặc biệt là tại thời điểm chẩn đoán ban đầu. Chúng tôi xin báo cáo một trường hợp lâm sàng hiếm gặp như vậy. BN đến khám vì triệu chứng đầy bụng và rối loạn tiêu hóa, nội soi đại tràng có hình ảnh tổn thương loét sùi ở manh tràng, được sinh thiết cho kết quả là ung thư biểu mô tuyến. Hình ảnh chụp cắt lớp vi tính (CLVT) ngực bụng cho thấy khối u ở thùy trên phổi trái, và sinh thiết tổn thương này cũng cho kết quả là ung thư biểu mô tuyến. Kết quả nhuộm hóa mô miễn dịch khẳng định tổn thương nguyên phát tại phổi và di căn manh tràng.

Bệnh nấm da là bệnh da liễu thường gặp, gây ra bởi các loài nấm thuộc ba giống Trichophyton, Epidermophyton và Microsporum. Trichophyton (T.) indotineae là loài nấm da mới được đặt tên, có tỷ lệ kháng terbinafine cao, đã được báo cáo ở nhiều nước châu Á, châu Âu và Bắc Mỹ. Trong bài báo này, chúng tôi thông báo ca bệnh nấm da do T. indotineae đầu tiên tại miền Bắc Việt Nam ở một phụ nữ 39 tuổi tới khám tại Bệnh viện Quân y 103. Người bệnh có tổn thương da đặc trưng, xét nghiệm trực tiếp và nuôi cấy vảy da cho kết quả dương tính với nấm da, chủng nấm sau khi phân lập được giải trình tự xác định là T. indotineae dựa vào chỉ thị gen ITS1-5.8S-ITS2. Người bệnh sau đó được điều trị thành công bằng phác đồ kết hợp itraconazole đường uống và ketoconazole bôi tại chỗ. Qua ca bệnh này có thể thấy bên cạnh việc kết hợp lâm sàng với xét nghiệm hình thái để chẩn đoán bệnh nấm da, việc ứng dụng các phương pháp sinh học phân tử để phát hiện chính xác căn nguyên gây bệnh là rất cần thiết để lựa chọn thuốc điều trị phù hợp và bổ sung thông tin dịch tễ của các loài nấm mới ở Việt Nam.

Mục tiêu: Đánh giá khả năng dự đoán kết quả hồi phục sau tiêu sợi huyết ở bệnh nhân (BN) đột quỵ nhồi máu não (ĐQNMN) cấp trên CT mạch não đa pha. Phương pháp nghiên cứu: Nghiên cứu hồi cứu cắt ngang trên 29 BN ĐQNMN cấp, đánh giá tuần hoàn bàng hệ trên CT mạch não đa pha và điều trị tiêu sợi huyết đường tĩnh mạch. Kết quả: Tuổi trung bình của nhóm BN nghiên cứu là 67,6 ± 11,7 năm, tỷ lệ nhóm tuổi 60 - 79 cao nhất (72,5%), tỷ lệ nhóm tuổi < 40 thấp nhất: 3,4%, tỷ lệ nam là 66,0%. NIHSS giảm ≥ 4 ở thời điểm 1 giờ và 24 giờ và điểm mRS ≤ 1 lúc ra viện có tuần hoàn bàng hệ mức tốt đều cao hơn so với nhóm có tuần hoàn bàng hệ trung bình lần lượt là 62,1%; 72,4% và 58,6% so với 13,7%; 13,7% và 10,3%. Diện tích dưới đường cong AUC của điểm tuần hoàn bàng hệ dự đoán khả năng hồi phục tốt ở thời điểm 1 giờ và 24 giờ sau điều trị alteplase tĩnh mạch và điểm mRS khi ra viện, đều < 0,6. Kết luận: Tuần hoàn bàng hệ trên CT mạch não đa pha có thể dự đoán kết quả hồi phục cho điều trị tiêu sợi huyết ở BN ĐQNMN cấp. Tuy nhiên, cần thêm các nghiêm cứu với cỡ mẫu lớn hơn.

Mục tiêu: Đánh giá mối liên quan của nồng độ SpCO với các biện pháp cấp cứu, chỉ số hô hấp khi vào viện của bệnh nhân (BN) bỏng hô hấp và đánh giá vai trò tiên lượng tỷ lệ tử vong của nồng độ SpCO đối với BN bỏng hô hấp. Phương pháp nghiên cứu: Nghiên cứu tiến cứu mô tả theo dõi dọc trên 76 BN bỏng hô hấp được chẩn đoán ngộ độc khí carbon monoxide (CO) bằng máy đo nồng độ SpCO. Kết quả: Nồng độ SpCO trung bình khi nhập viện ở các BN bỏng hô hấp có tình trạng ngộ độc là 15,7 ± 4,14%. Các chỉ số hô hấp ở BN ngộ độc gồm PaO2 194,8 ± 127,4 mmHg, SpO2 97,04 ± 3,5%. Không có sự khác biệt về tỷ lệ tử vong ở BN bỏng hô hấp ngộ độc CO (p = 0,21). Kết luận: Các BN bỏng hô hấp có các chỉ số hô hấp không thể hiện tình trạng thiếu oxy do ngộ độc CO. Nồng độ SpCO không phải là yếu tố nguy cơ ảnh hưởng đến tỷ lệ tử vong ở BN bỏng hô hấp khi được điều trị đúng phác đồ.

Dấu ấn sinh học phân tử trong ung thư là các phân tử có thể đo lường và cung cấp thông tin về sự hiện diện, tiến triển hoặc phản ứng với việc điều trị một loại ung thư cụ thể. Những phân tử này có thể được phát hiện trong mô hoặc dịch cơ thể như máu, nước tiểu, phân… Việc xác định các dấu ấn sinh học ung thư đóng một vai trò quan trọng trong nhiều khía cạnh khác nhau của nghiên cứu ung thư và thực hành lâm sàng như phát hiện, chẩn đoán, theo dõi và phát triển các phương pháp điều trị ung thư. Các ứng dụng lâm sàng của dấu ấn sinh học rất rộng rãi. Hiện nay, với sự phát triển của khoa học, kỹ thuật, các phương pháp phát hiện dấu ấn phân tử ung thư ngày càng hiện đại và hiệu quả. Chính vì thế, việc hiểu rõ về dấu ấn sinh học phân tử ung thư là một việc quan trọng để có thể phát triển dấu ấn sinh học mới với độ nhạy, độ đặc hiệu cao hơn và giá trị lâm sàng tích cực hơn.
