Early detection of lung nodule is of great importance for the successful diagnosis and treatment of lung cancer. Many researchers have tried with diverse methods, such as thresholding, computer-aided diagnosis system, pattern recognition technique, backpropagation algorithm, etc. Recently, convolutional neural network (CNN) finds promising applications in many areas. In this research, we investigated 3D CNN to detect early lung cancer using LUNA 16 dataset. At first, we preprocessed raw image using thresholding technique. Then we used Vanilla 3D CNN classifier to determine whether the image is cancerous or non-cancerous. The experimental results show that the proposed method can achieve a detection accuracy of about 80% and it is a satisfactory performance compared to the existing technique.

The Recurrence of Natural Disasters in Jowhar, Middle Shabelle Region, Somalia: The Causes and Impacts

引用

Journal of Environmental Protection 2022年第9期13卷 657-670页

作者： Mohamed Ali Ahmed Mohamed Hassan Mohamed mst. Mahmuda parvin Predrag Ilić Department of Environmental Science Stamford University Bangladesh Dhaka Bangladesh Department of Public and Environmental Health Somali International University Mogadishu Somali PSRI Institute for Protection and Ecology of the Republic of Srpska Banja Luka Bosnia and Herzegovina

Natural disasters usually involve a phenomenon with consequences that exceed the response capabilities of local communities and have a significant impact on the region’s socioeconomic development. Droughts, floods, and hurricanes are all natural disasters that jeopardize the environment and the lives of Somalis. Severe floods have devastated the south and central parts of the country multiple times, destroying infrastructure and homes and killing many vulnerable people. Droughts in the south and central parts of the country, particularly in the Middle Shebelle region, have killed a number of children and mothers. It also had a negative influence on crops and cattle. Objective of this study is to know the recurrence of Natural Disasters in Jowhar, Middle Shabelle region, Somalia: The Causes and Impacts. The Somali people are completely aware of natural disasters such as droughts and floods, and they are self-sufficient in dealing with the consequences of these disasters. Furthermore, the Somali government has not fully created environmental laws to protect and conserve the environment, and the majority of laws, rules, acts, and regulations are not used or administered effectively. We also found that the Somali government is not yet financially prepared to deal with these crises, and that there are no strategic plans in the central government or even state administrations to prevent or at least control these disasters from causing extreme harm to the community and the environment.

Studies on the anti-diarrheal properties of leaf extract of Desmodium puchellum

引用

Asian Pacific Journal of Tropical Biomedicine 2013年第8期3卷 639-643页

Objective:To evaluate the pharmacological activity against diarrhea of methanol and petroleum ether extract ofDesmodium puchellum(Family:Fabaceae)***:The extract was evaluated for castor oil-induced diarrhea and enteropooling as well as intestinal motility in *** of the extracts were given to the rats at 200 mg/kg *** was used as a standard drug for ***:The diarrheal severity was reduced significantly(P<0.05)by methanol and petroleum ether extracts by 31.95% and 28.33%,respectively,whereas 54.75% inhibition was found for standard drug loperamide at 5 mg/*** two extracts also significantly(P<0.05) reduced the intestinal volume in case of castor oil induced ***:It is concluded that both fractions contain some biologically active ingredients that are active for anti-diarrheal actions whereas methanol fraction has better potential.
