Published: December 2023

Over the last few decades, neuroimaging, particularly magnetic resonance imaging (MRI), has played a significant sessional part in studying brain functions and diseases. MRI images, combined with unique ML approaches and developed tools during these years, have opened up new opportunities for diagnosing neurological illnesses. However, due to the apparent symptoms that are similar to each other, brain illnesses are regarded as difficult to precisely detect. This research examines a newly developed algorithm (ParkinsonNet) to classify Parkinson's disorder into two unique classes which are Control (healthy) and Parkinson's (PD), this method is one of the deep learning approaches, Convolutional neural networks (CNN). CNN is one way that may be used to classify a range of brain illnesses such as Parkinson's. We employed a freshly constructed CNN technique from scratch, and we got 97.9% accuracy which is considered outstanding compared with recently published articles using the same dataset

Abstract
Many researchers have conducted studies on Hamka. However, studies on the rationalization of the interpretation of verses about Heaven and tracing the causes of the rationalization of performance have yet to be carried out. Therefore, the researcher was interested in conducting this study further. The type of this research is library research with a descriptive-analytical method. The genealogical theory of Michel Foucault explains the genealogy of Hamka's interpretation of thought. The conclusion of this article explains that, Firstly, Hamka attempts to make a rational and contextual interpretation of the verses describing Heaven. With the method of sensible and contextual performance, the metaphysical and abstract nature of Heaven becomes easily understood by readers (society), moreover explained by Hamka in simple language and explanation. Secondly, Hamka's rationalist thinking and contextual typology of description were influenced by several factors, including his life experience as a preacher, writer, organization, and his teachers. Thirdly, Hamka's interpretation of the verses about Heaven accommodates educational values ​​between humans and God and also among humans.

Trong nuôi cá cảnh nói chung, màu sắc đóng một vai trò rất quan trọng ảnh hưởng trực tiếp đến giá trị và sự chấp nhận của thị trường. Mặc dù đã đạt được thành công trong sản xuất giống nhiều loài trong giống cá khoang cổ nhưng màu sắc kém của nguồn cá này so với cá hoang dã là một trong những thách thức lớn hiện nay. Để giải quyết vấn đề này, chúng tôi sử dụng astaxanthin tách chiết từ Copepoda, loài Pseudodiaptomus annandalei, bổ sung vào thức ăn nhằm cải thiện màu sắc của cá khoang cổ nemo, Amphiprion ocellaris. Năm hàm lượng astaxanthin, 50 – 450 mg/kg thức ăn, và một nghiệm thức đối chứng đã được thử nghiệm. Cá được nuôi trong các bể kính, 60 lít/bể, với mật độ 15 con/bể. Mỗi nghiệm thức được thực hiện với 3 lần lặp trong 75 ngày. Kết quả cho thấy các chỉ số đánh giá hiệu quả cải thiện màu sắc như a* (xanh lá – đỏ), b* (xanh dương – vàng), Hoab (tông màu), C*ab (độ bão hòa màu), ΔE* (khác biệt màu sắc tổng thể) và hàm lượng carotenoids tích lũy (da và cơ thịt) đạt được tốt hơn cùng với mức tăng của hàm lượng astaxanthin bổ sung (P < 0,05). Mức độ đỏ và hàm lượng carotenoids tích lũy trên da cá ở nghiệm thức 450 mg/kg đạt cao nhất, cao hơn lần lượt là 111% và 270% so với đối chứng. Nghiên cứu cung cấp một giải pháp hiệu quả nhằm cải thiện màu sắc của cá khoang cổ nemo, qua đó, góp phần nâng cao chất lượng con giống sản xuất đáp ứng nhu cầu thị trường.
Keywords: Astaxanthin, cá khoang cổ nemo, Copepoda, hàm lượng carotenoid tích lũy, màu sắc.

Hormone HCG được sử dụng tiêm 2 lần cho cá cái: 300 UI/kg cá (lần 1), 500 UI/kg cá (lần 2); cá đực chỉ tiêm 01 lần 400 UI/kg cá. 03 phương pháp thụ tinh được sử dụng gồm: thụ tinh khô (tinh + trứng), thụ tinh ướt (tinh + nước + trứng) và thụ tinh tự nhiên (đẻ tự nhiên không vuốt tinh và trứng). Kết quả cho thấy thụ tinh ướt có tỷ lệ thụ tinh đạt cao nhất 91,81%, tiếp đến là phương pháp thụ tinh khô đạt 88,44% và thấp nhất là phương pháp thụ tinh tự nhiên đạt 75,92%. Không có sự khác biệt có ý nghĩa về tỷ lệ thụ tinh giữa thụ tinh khô và thụ tinh ướt (P>0,05), tuy nhiên có sự khác biệt lớn giữa 2 phương pháp thụ tinh này so với thụ tinh tự nhiên (P<0,05). Không có sai khác có ý nghĩa giữa 3 phương pháp thụ tinh đối với tỷ lệ nở của cá gáy (P>0,05). Phương pháp thụ tinh ướt được sử dụng trong thí nghiệm mật độ. Thí nghiệm bố trí ở 03 mật độ ấp trứng khác nhau: 1.000 trứng/L; 1.500 trứng/L và 2.000 trứng/L. Kết quả nghiên cứu cho thấy thời gian phát triển phôi của cá gáy dao động từ 14,10 giờ đến 14,50 giờ, sau đó trứng nở thành cá bột. Không có sự khác biệt về thời gian phát triển phôi ở các mật độ khác nhau (P>0,05). Tỷ lệ nở đạt cao nhất ở mật độ ấp 1.000 trứng/L (90,33%), tiếp theo là mật độ ấp 1.500 trứng/L (90,08%) và không có sự khác biệt lớn giữa 02 mật độ này (P>0,05), tuy nhiên có sự khác biệt thống kê giữa 02 mật độ này so với mật độ 2.000 trứng/L (87,84%; P<0,05). Tương tự tỷ lệ nở, tỷ lệ sống của cá bột 5 ngày tuổi đạt cao nhất ở mật độ 1.000 trứng/L (48,51%), tiếp đến mật độ 1.500 trứng/L (48,14%), không có sử khác biệt giữa 02 mật độ ấp này (P>0,05). Tỷ lệ sống đạt thấp nhất ở mật độ ấp 2.000 trứng/L (46,14%) và có khác biệt thống kê so với 02 mật độ trên (P<0,05). Tỷ lệ cá dị hình ở các nghiệm thức dao động 3,23 – 3,72%, không có sự khác biệt thống kê giữa mật độ ấp 1.000 trứng/L và 1.500 trứng/L (P>0,05). Tuy nhiên, có sự khác biệt về tỷ lệ dị hình ở 02 mật độ ấp này so với mật độ ấp 2.000 trứng/L (P<0,05). Phương pháp thụ tinh ướt và ấp trứng ở mật độ 1.500 trứng/L mang lại hiệu quả cao trong sản xuất giống nhân tạo so với các phương pháp khác được sử dụng trong nghiên cứu này.

Mô phỏng mối tương quan giữa lượng phát thải bồ hóng và áp suất phun nhiên liệu của động cơ diesel tàu cá
Authors: Mai Đức Nghĩa , Hồ Đức Tuấn
Published: December 2023

Động cơ diesel dùng làm máy chính của tàu đánh cá thường phải kiểm tra, bảo dưỡng, sửa chữa trước khi tàu đánh bắt xa bờ để bảo đảm an toàn và hiệu quả khi hoạt động trên biển dài ngày. Trong đó, vòi phun được tháo để cân chỉnh áp suất phun nhiên liệu về giá trị tiêu chuẩn để các chỉ tiêu công tác của động cơ đạt yêu cầu. Một trong các thông số có thể giúp đánh giá sự suy giảm áp suất phun trong quá trình động cơ làm việc là lượng phát thải bồ hóng, thông qua nó có thể đánh giá tình trạng vòi phun nhiên liệu, góp phần đề ra giải pháp bảo dưỡng, sửa chữa phù hợp, hạn chế thời gian và kinh phí. Bài báo này trình bày nội dung nghiên cứu mô phỏng đối với động cơ Yanmar 4CHE của tàu cá bằng phần mềm AVL-Boost. Kết quả cho thấy khi áp suất phun nhiên liệu suy giảm 5-10% so với tiêu chuẩn, phát thải bồ hóng tăng trên 20%.
