Authors: Cheng Linying , Li Jing , Liu Yunlei
Published: August 2024

Film, as one of the mainstream media in the 21st century, has shaped societal norms, which molds public perceptions and values. With the emergence of feminism in the 21st century, it can be witnessed an increasing trend in the appearance of films on the theme of feminism. However, in the Chinese film industry, most of the positions are predominated by men (usually defined as director, producer, and writer), leaving women significantly underrepresented. This study aims to dissect the context of two films, "I am Not Madame Bovary" and "Lost in the Star", which are feminist-theme content directed by male directors. Through the detailed analysis, this study finds the underrepresentation of female voices within the film industry, along with its impact on the depiction of women and their interpersonal dynamics. This research underscores the contrast between the ostensible neutrality of film narratives and the inherent male-oriented discourse that sidelines female perspectives, which silence women's voices in the narrative fabric.

Authors: Ma Yiqing
Published: August 2024

Under the action of in-plane biaxial stress, the electronic structure properties of the two-dimensional AlN/SiC heterostructure were studied by first principles. The two-dimensional AlN/SiC heterostructure has an indirect band gap in its original state, and the band gap can be adjusted under -10%~10% biaxial strain, without the transition to direct band gap and metal. The application of in-plane biaxial stress can effectively adjust the electronic characteristics. Based on the calculation of the energy band, the influence of the external biaxial tensile strain on the effective carrier mass is discussed. The results show that the band gap of the two-dimensional semiconductor material can be adjusted by the in-plane biaxial strain. It has the expected application value.
The Transformation of Dynamic Network State in Ischemic Stroke
Authors: Li Moxin
Published: August 2024

Ischemic stroke is a common disease of the nervous system, which poses a serious threat to human health due to its high disability rate and mortality rate, among which ischemic stroke occupies the first place. According to the Chinese National Stroke Registry Study, the crude and standardized prevalence of stroke in people over 40 years of age is 2.0% and 1.9% [1]. Because of its high disability rate and mortality, it is very important to accurately evaluate the disease condition and prognosis in the early stage of the disease. There are many methods to judge the severity of stroke patients, and the most widely used ones are clinical scale and imaging examination. In order to detect the onset of ischemic stroke early, it is important to identify specific electroencephalogram (EEG) dynamics and resting state fMRI for the transformation of brain activity during the onset of ischemic stroke. In this study, we investigated the transition of brain activity from interseizure to preseizure states, combining EEG networks at different frequency bands and cluster analysis combined with resting state fMRI to consider changes in patients' brain networks. These findings may provide useful insights into the pathogenesis of ischemic stroke and can also be used for prediction and subsequent intervention of ischemic stroke onset.

Authors: Kulla Prerana , Tang Sophia
Published: August 2024

This study evaluated the effects of several ink types on the biodegradability of cellulose. Paper is one of the main components of cellulosic waste, which is a major environmental problem worldwide. The effects of several ink types, such as alcohol-based, water-based, algae-based, and oil-based inks, on the degradation of cellulose were studied. Given the abundance of cellulose in many everyday commodities, cellulose breakdown is essential for waste management and environmental sustainability. A new cellulase-producing fungus discovered in Burke County was used in the study to evaluate how filter paper treated with various inks degraded. Different types of inks showed different levels of degradation based on visual observations; oil- and alcohol-based inks showed negligible degradation, whereas water and algae-based inks showed significant degradation. The qualitative observations were verified by quantifying enzyme activity and substrate degradation through spectrophotometer experiments. According to statistical analysis, inks based on water and algae degraded cellulose at higher rates than control samples, while inks based on oil and alcohol degraded at lower rates. The study shows how various ink types affect the environmental impact of cellulose biodegradability and highlights the possibilities of water- and algae-based inks as sustainable substitutes. To further understand the precise mechanisms behind ink impacts on cellulose degradation and to optimize ink formulations for increased environmental sustainability, more research is necessary.

Dalam budidaya larva ikan, pemberian pakan buatan dimungkinkan setelah enzim pencernaan dihasilkan. Untuk meningkatkan kemampuan larva dalam memanfaatkan pakan buatan, penelitian ini mengusulkan penambahan enzim eksternal ke dalam pakan. Tujuan penelitian adalah untulk menentukan dosis optimal enzim papain dan stadia pemberian pakan buatan pra-pencernaan terhadap Tingkat metamorphosis dan kandyungna glikogen dalam larva kepiting bakau (Scylla Olivacea). Penelitian ini menggunakan desain factorial dalam rancangan acak lengkap, dengan faktor pertama yaitu dosis enzim papain (0%, 1,0%, 2,0%, 3,0%), sedangkan factor kedua adalah stadia pemberian pakan buaan pra-perencanaan (zoea 2 dan zoea 3). Hasil penelitian menunjukkan bahwa variasi dosis enzim papain dan stadia pemberian pakan buatan pra-perencanaan memberikan pengaruh yang signifikan (p<0,05) terhadap Tingkat metamorphosis pada larba yang berumur 9, 10, 12, 13, 16, dan 17 hari. Namun, interaksi antara kedua factor tidak menunjukkan pengaruh yang signifikan (p>0,05). Tingkat metamorfosis pada dosis enzim papain 0% dan 1,5% membutuhkan waktu lebih lama dan secara signifikan berbeda (p<0,05) dibandingkan dengan dosis 3% dan 4,5%. Selain itu, dosis enzim papain juga memengaruhi kandungan glikogen dalam larva, di mana dosis 4,5% menunjukkan kandungan glikogen yang signifikan lebih tinggi dibandingkan dengan dosis 1,5% dan 3,0%. Meskipun demikian, kandungan glikogen pada dosis 0%, 1,5%, dan 3,0% tidak menunjukkan perbedaan yang signifikan. Berdasarkan hasil penelitian, disarankan menggunakan dosis enzim papain sebesar 4,5% untuk menghidrolisis protein pakan dengan efektif.

Published: August 2024

The article examines the role of agroecology in sustainable rural development in Ecuador, highlighting its economic, environmental and social benefits. Agroecology reduces production costs by reducing dependence on external inputs, improves profitability and diversifies income, allowing farmers to access niche markets. Environmentally, it promotes biodiversity conservation, improves soil quality, reduces pollution and contributes to climate change mitigation. Socially, it strengthens rural communities, empowers farmers, improves food security and preserves traditional knowledge. However, its adoption faces significant barriers, such as lack of institutional support, poor training, cultural resistance and limited access to financial resources. To maximize its potential, it is recommended to develop favorable public policies, accessible training programs, strategies to change cultural perceptions and adequate financial mechanisms.

Authors: Guamán-Rivera Santiago Alexander
Published: August 2024

The study analyzes the influence of agricultural policies on Ecuador's small farmers, highlighting both advances and challenges. Subsidies and technical assistance policies have increased productivity but have disproportionately favored large producers. Small farmers face significant barriers such as limited access to credit, insufficient ongoing technical assistance, market instability and land tenure problems. Despite some improvements in rural poverty reduction, regional inequalities and a notable rural-urban drift persist. To improve policy effectiveness, it is recommended that inclusive policies be designed, technical assistance be strengthened, access to financing be facilitated and rural infrastructure be developed. These measures are essential to promote sustainable and equitable agricultural development, improving the quality of life of small farmers in Ecuador.
