Post-acute care(PAC)residents in nursing homes(NHs)are recently hospitalized patients with medically complex diagnoses,ranging from severe orthopedic injuries to cardiovascular diseases.A major role of NHs is to maximize restoration of PAC residents during their NH stays with desirable discharge outcomes,such as higher community discharge likelihood and lower re/hospitalization risk.Accurate prediction of the PAC residents’length-of-stay(LOS)with multiple discharge dispositions(e.g.,community discharge and re/hospitalization)will allow NH management groups to stratify NH residents based on their individualized risk in realizing personalized and resident-centered NH care delivery.Due to the highly heterogeneous health conditions of PAC residents and their multiple types of correlated discharge dispositions,developing an accurate prediction model becomes challenging.Existing predictive analytics methods,such as distribution-/regression-based methods and machine learning methods,either fail to incorporate varied individual characteristics comprehensively or ignore multiple discharge dispositions.In this work,a data-driven predictive analytics approach is considered to jointly predict the individualized re/hospitalization risk and community discharge likelihood over time in the presence of varied residents’characteristics.A sampling algorithm is further developed to generate accurate predictive samples for a heterogeneous population of PAC residents in an NH and facilitate facility-level performance evaluation.A real case study using large-scale NH data is provided to demonstrate the superior prediction performance of the proposed work at individual and facility levels through comprehensive comparison with a large number of existing prediction methods as benchmarks.The developed analytics tools will allow NH management groups to identify the most at-risk residents by providing them with more proactive and focused care to improve resident outcomes.

Improved Self-Pruning for Broadcasting in Ad Hoc Wireless Networks

Wireless Sensor Network 2017年第2期9卷 73-86页

作者： Raqeebir Rab Shaheed Ahmed Dewan Sagar nazmus sakib Ahasanul Haque Majedul Islam Ashikur Rahman Department of Computer Science and Engineering Ahsanullah University of Science and Technology Dhaka Bangladesh Department of Computer Science and Engineering Bangladesh University of Engineering and Technology (BUET) Dhaka Bangladesh

Reducing number of forwarding nodes is the main focus of any broadcasting algorithm designed for ad-hoc wireless networks. All reliable broadcasting techniques can be broadly classified under proactive and reactive approaches. In proactive approach, a node selects a subset of its neighbors as forwarding node and announces the forwarding node list in the packet header during broadcast. On the other hand, no such forwarding list is generated in reactive approach. Rather, a node (cognitively) determines by itself whether to forward the packet or not based on neighbor information. Dominant pruning and Self-pruning are two example techniques that fall under proactive and reactive approach respectively. Between the two methods, dominant pruning shows better performance than self-pruning in reducing number of forwarding nodes as they work with extended neighbor knowledge. However, appended forwarding node list increases message overhead and consumes more bandwidth. As a result, the approach becomes non-scalable in large networks. In this paper, we propose a reactive broadcasting technique based on self-pruning. The proposed approach dubbed as “Improved Self-pruning based Broadcasting (ISB)” algorithm completes the broadcast with smaller packet header (i.e., with no overhead) but uses extended neighbor knowledge. Simulation results show that ISB outperforms dominant pruning and self-pruning. Furthermore, as the network gets more spread and denser, ISB works remarkably well.

In Bangladesh, Fish is a major source of daily protein intake of millions of people but most of the fishes are consumed here as fresh fish which is highly susceptible to damage during transportation and marketing. Therefore, an innovative approach was undertaken to process the fish to avoid damage and extend shelf-life while preserving the nutritional qualities to facilitate the more efficient use of fish as a source of protein and other essential nutrients. This study was conducted to develop some dried protein-enriched fish powders from some commonly consumed fish species in Bangladesh and the nutritional, sensorial, and safety qualities were assessed. Five indigenous abundant fish species including small indigenous fish (SIS) and carp fishes namely Awaous grammepomus, Channa punctata, Puntius puntio, Hypophthalmichthys molitrix and Labeo rohita were used for the preparation of dried protein-enriched fish powders. Biochemical, trace elements, sensorial, total viable count (TVC), pH, peroxide value, and moisture reconstitution during 90 days storage period were performed by standard analytical methods. The moisture, protein, fat, ash, carbohydrate (including fiber), and energy contents were ranged from (6.84% to 8.85%), (70.80% to 75.80%), (5.85% to 8.04%), (7.66% to 9.19%), (3.14% to 6.01%) and (367.50% to 379.61% kcal)/100g respectively. Highest content of protein was found in A. grammepomus (75.80%) samples and the lowest in H. molitrix (70.80%) samples. Maximum calcium content was found in sample L. rohita (2.54 g/kg) and minimum in C. punctate as (2.43 g/kg). Maximum iron content was found in H. molitrix (0.15 g/kg) and minimum in A. grammepomus. As for the phosphorous content the L. rohita samples contained the highest (1.4 g/kg) and the lowest in C. punctate (0.73 g/kg) samples. The pH, peroxide value (mEq of O2/kg of fat), and moisture reconstitution (g/100g) during 90 days were ranged from (5.30 to 8.17), (8.60 to 16.77), and (6.84 to 13.83) respectively. Microbial loads over the 90 days period were in

Comparison between Tencel-Flax Blended Slub Yarn and Cotton-Flax Blended Slub Yarn

引用

Journal of Textile Science and Technology 2022年第4期8卷 221-230页

作者： Mohammad Nayemul Islam Lamia Latifun Rahman Md. Imran Hosen Jaglul Hoque Mridha Md. sakib-Uz-Zaman Md. Shahin Hossen nazmus sakib Khan Department of Textile Engineering Sonargaon University Dhaka Bangladesh Department of Textile Engineering Primeasia University Dhaka Bangladesh Epyllion Limited Epyllion Group Dhaka Bangladesh Auxicolour Bangladesh Limited Dhaka Bangladesh

The blending of different fibers is done for the manufacturing of yarn to ensure the presence of multiple properties in the resultant yarn which is impossible if we use only one type of fiber. Tencel is regenerated cellulosic fiber & flax is natural bast fiber. Tencel shows more versatility than flax. Tencel has a softer feel with a variety of end uses. Tencel is wrinkle-prone and stiff. Tencel shows extreme strength even in wet conditions and at the same time, it is more durable than linen. The most important fact is that the heat dissipation property of flax is 5 times higher than wool & 19 times higher than silk. Linen clothing can lower the body temperature by 3 to 4 degree celsius in hot weather than clothing made of wool and silk. A yarn made of both Tencel & linen (50:50) will contain the properties of both fibers. At the same time, we can make this yarn more aesthetic by incorporating a slub. It was observed that the slub yarn made by blending Tencel and flax fiber shows better properties than the slub yarn of the same count made from the blending of cotton and flax.

Investigation of Antibacterial, Cytotoxic and Antioxidant Properties of the Mangrove Plant Xylocarpus mekongensis

引用

Advances in Bioscience and Biotechnology 2016年第4期7卷 205-213页

作者： Mahmuda Akter Sadia Afrin Sk. nazmus sakib Rana Biswas Md. Morsaline Billah Mohammad Shahedur Rahman Umme Salma Zohora Biotechnology and Genetic Engineering Discipline Khulna University Khulna Bangladesh Department of Biotechnology and Genetic Engineering Jahangirnagar University Dhaka Bangladesh

The plant (Xylocarpus mekongensis) of the Sundarbans mangrove origin was evaluated for its antibacterial, cytotoxic and antioxidant properties using methanolic and chloroformic leaf, stem and bark extracts, respectively. The methanolic extracts contained higher amount of total phenolics, flavonoids, tannins than the chloroformic extracts and the result was in correlation with their ferric reducing power ability as well. However, the chloroformic bark extract contained more potent DPPH free radical scavenging activity than others. Antibacterial activity of the extracts was determined against both Gram-positive (Micrococcus and Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Vibrio cholerae, Salmonella typhimurium and Salmonella paratyphi) by disc diffusion assay and their zone of inhibitions (ZOI) were measured. Moreover, their minimum inhibitory concentrations (MIC) were determined by tube dilution method. Chloroformic bark and stem extracts showed strong inhibition to growth of P. aeruginosa (ZOI = 19 mm and MIC = 150 μg/ml) and S. aureus (ZOI = 19.5 mm and MIC = 250 μg/ml), respectively. All six extracts were subjected to brine shrimp lethality bioassay for possible measure of cytotoxicity. Concentration dependent increment in percentage mortality of brine Shrimp nauplii produced by the extracts indicated the presence of cytotoxic principles in these extractives. Therefore, Xylocarpus mekongensis showed antioxidant, antibacterial and cytotoxic activities.
