The increased adoption of.Internet of.medical Things (IomT) technologies has resulted in the widespread use of.ody Area Networks (BANs) in medical and non-medical domains. However, the perf.rmance of.IEEE 802.15.4-based BANs is impacted by challenges related to heterogeneous data traf.ic requirements among nodes, includingcontention during f.nite backof. periods, association delays, and traf.ic channel access through clear channelassessment (CCA) algorithms. These challenges lead to increased packet collisions, queuing delays, retransmissions,and the neglect of.critical traf.ic, thereby hindering perf.rmance indicators such as throughput, packet deliveryratio, packet drop rate, and packet delay. Theref.re, we propose Dynamic Next Backof. Period and Clear ChannelAssessment (DNBP-CCA) schemes to address these issues. The DNBP-CCA schemes leverage a combination of.he Dynamic Next Backof. Period (DNBP) scheme and the Dynamic Next Clear Channel Assessment (DNCCA)scheme. The DNBP scheme employs a f.zzy Takagi, Sugeno, and Kang (TSK) model’s inf.rence system toquantitatively analyze backof. exponent, channel clearance, collision ratio, and data rate as input parameters. Onthe other hand, the DNCCA scheme dynamically adapts the CCA process based on requested data transmission tothe coordinator, considering input parameters such as buf.er status ratio and acknowledgement ratio. As a result,simulations demonstrate that our proposed schemes are better than some existing representative approaches andenhance data transmission, reduce node collisions, improve average throughput, and packet delivery ratio, anddecrease average packet drop rate and packet delay.

具有除菌性能的电容去离子材料对于制备高效节能同时具备脱盐和抗微生物污染功能的电极材料至关重要,然而由于双电层电吸附机制的影响,多数碳基材料的吸附容量受到限制.同时,近年来部分研究学者通过对电极材料进行抗菌化合物的修饰并用于电容法水除菌已得到证明.因此为了实现高效、低成本的同时实现电容脱盐和除菌,本研究提出了一种简便的方法制备氧化石墨烯/聚苯胺/普鲁士蓝纳米复合材料作为类法拉第电极用于电容去离子和水消毒应用.所合成的电极材料具有较高的BET表面积(148.08m^(2)g^(-1))、介孔体积(34.02cm^(3)g^(-1))和孔体积(0.66cm^(3)g^(-1)),在1Ag^(-1)下的脱盐容量为91.6mgg^(-1),脱盐率为3.05mgg^(-1)min^(-1).此外,在未添加额外消毒剂的情况下,该复合材料所制备的电极能有效去除和灭活94.0%±3.1%的大肠杆菌,其杀菌效率是活性炭电极的7倍.本研究对未来将普鲁士蓝基复合材料的法拉第电极用于高效环保海水淡化和消毒材料的应用奠定了研究基础.

The optimum levels of.Lysine and Glutamine needed f.r growth perf.rmance and maintenance of.the chicken broilers were evaluated in a randomized 3 × 4 f.ctorial arrangement of.dietary treatments. The battery cages measured 99 × 66 × 25 cm that can be suf.icient f.r 5 birds. Day old Chicken broilers totaling 180 were assigned to dietary treatments comprising of.3 concentrations of.Lysine (0.85, 1.14, and 1.42) each in combination with 4 concentrations of.Glutamine (0, 1, 2, and 3). Each dietary treatment was replicated 3 times and each replication had 5 birds. The birds were given f.ed and water ad libitum with a 23-hour light regimen f.r a period of.4 weeks. Then, the experimental birds were evaluated f.r body weight gain, f.ed consumption, and f.ed conversion in order to determine their optimum requirement f.r dietary Lysine and Glutamine. Based on the f.ndings of.this study, the highest perf.rmance was observed in birds f.d the diet supplemented with 1.42 lysine and 1% glutamine, but the highest improvement in f.ed conversion was observed in diet contain 1.14 and 1.42 with 1% and 3% glutamine, respectively. Birds f.d 1.42 lysine and 1% glutamine had the highest total body weight gain and f.ed consumption. The lysine requirements in the diet f.r Chicken are between 1.14 and 1.42 with glutamine level of.1%.
