CNN-BLSTM Joint Technique on Dynamic Shape and Appearance of FACS
No full textFacial recognition is a process where we can identify or verify a person from digital image or videos and is used in ID verification services , protecting law enforcement ,preventing retail crime etc. Past work on automatic analysis of facial expression focuses on detecting the facial expression and exploiting the dependencies among AU’s. But, spontaneous detection of facial expression depending on various factors such as shape, appearance and dynamics is very difficult. Joint learning of shape , appearance and dynamics is done by a deep learning technique .This includes a convolutional neural networks and bidirectional long short term memory(CNN-BLSTM). This combination of CNN-BLSTM excels the modeling of temporal information. FERA2015 dataset achieves the state of art.
Changes of Postharvest Nutritional Quality and Antioxidant Enzymes in ‘Haribhanga’ Mango by Aloe vera Gel with Chitosan and Coconut Oil Coating During Ambient Storage
No full textMango is a well-known tropical climacteric fruit that decays rapidly. Thus, a postharvest management strategy utilizing natural and biodegradable materials is necessary to minimize crop losses. The study evaluated the coating effects of A. vera gel with chitosan and coconut oil on postharvest features and mango shelf life throughout 15 days of storage at room temperature (25 ± 2 °C). Fruits were treated with the following six coatings: control (distilled water), 1.5% chitosan solution (CH) (w/v), Aloe vera gel (AV) (1 : 1, v/v), coconut oil (CO) (1 : 1, v/v), 1.5% chitosan solution + A. vera gel (CH + AV) (1 : 1, v/v), and coconut oil + A. vera gel (CO + AV) (1 : 1, v/v). The findings showed that the coating with A. vera gel and chitosan significantly decreased decay, weight loss, respiration rate, and ethylene production compared to control. This coating improved fruit quality indicators like acidity, total soluble solids, pH, fruit firmness, and ascorbic acid content. Additionally, the phenol content and antioxidant activity decreased slightly during storage, while the control fruits demonstrated a rapid decrease in phenol content and antioxidant activity. Coated fruits significantly reduced the activity of polyphenol oxidase, whereas control fruits had the lowest catalase and peroxidase activity throughout the storage period. Coated fruit skin showed higher L* and b* values than the control fruits throughout storage. These findings suggested that A. vera gel with chitosan coating might preserve bioactive components and postharvest ‘Haribhanga’ mango fruit quality under ambient storage
Diversity, Abundance, and Seasonal Variation of Aquatic Macrophytes in Southeastern Bangladesh
No full textThe study was conducted to assess the diversity and abundance of aquatic macrophytes in the southeastern region of Bangladesh, encompassing the Noakhali, Cumilla, and Chandpur districts. The study was carried out over the period of July 2022 to June 2023. This research utilized a mixed-methods approach, incorporating observation of the study area, qualitative interviews, and quantitative surveys. Five types of aquatic macrophytes, 47 species from 18 orders and 25 families were identified. These are free-floating, rooted-floating, emergent, submerged, and marginal. Among the three locations, Noakhali was recorded as the highest with 44 species, followed by Cumilla with 43, and Chandpur with 35. In Noakhali, seasonal variation analysis showed that 39% of species were found in the rainy season, 14% in summer, 14% in winter, and 20% year-round. In Cumilla, 35% of aquatic macrophytes were available in the rainy season, and 14%, 12%, and 5% in winter, spring, and autumn, respectively. In Chandpur, 37% of aquatic macrophytes were prevalent in the rainy season, 26% were found year-round, 9% in winter, 14% in summer, and 6% each in spring and autumn. In Noakhali, 44% of macrophytes were frequent, 33% moderate, and 23% rare. In Cumilla, 49% were frequent, 44% moderate, and 14% rare. Chandpur reported 49% frequent, 31% moderate, and 20% rare species. The order Alismatales emerged as the dominant order comparatively across all locations. This research will provide insights into the biodiversity of aquatic macrophytes in this area, thus supporting effective management strategies
Understanding patient and family experiences of critical care in Bangladesh and India: What are the priority actions to promote person-centred care?
No full textPatients’ experiences in the intensive care unit (ICU) can enhance or impair their subsequent recovery. Improving patient and family experiences on the ICU is an important part of providing high quality care. There is little evidence to guide how to do this in a South Asian critical care context. This study addresses this gap by exploring the experiences of critically ill patients and their families in ICUs in Bangladesh and India. We elicit suggestions for improvements from patients, families and staff and highlight examples of practices that support person-centred care. This multi-site hospital ethnography was carried out in five ICUs in government hospitals in Bangladesh and India, selected using purposive sampling. Qualitative data were collected using non-participant observation and semi-structured interviews and analysed using reflexive thematic analysis. A total of 108 interviews were conducted with patients, families, and ICU staff. Over 1000 hours of observation were carried out across the five study sites. We identified important mediators of patient and family experience that span many different aspects of care. Factors that promote person-centred care include access to ICU for families, support for family involvement in care delivery, clear communication with patients and families, good symptom management for patients, support for rehabilitation, and measures to address the physical, environmental and financial needs of the family. This study has generated a list of recommendations that can be used by policy makers and practitioners who wish to implement person-centred principles in the ICU
