Drying of the banana in the hot water has a negative im.act on the quality of the product and drying effect. The purposes of this study are increasing the drying rate, using the relatively low tem.erature to im.rove the quality (40℃, 50℃ and 60℃) and investigate the use of electrom.gnetic waves to increase the drying speed. Therefore, experim.nts are perform.d using 5 kHz,10 kHz and 15 kHz low frequency electrom.gnetic waves in the air velocity values of 0.5 m.s, 1 m.s, 1.5 m.s and 2 m.s and 40℃, 50℃, 60℃ centigrade degrees of air blast in a special com.artm.nt. m.them.tical m.del of the drying process has been created as using the electrical circuits m.thods and experim.ntal results. As a result, a sim.le equation describing the drying process has been obtained. Nonlinear expression of the diffusion coefficient for a different situation in this equation has been identified for the first tim.. The obtained theoretical results and experim.ntal results have been provided a good agreem.nt. This study is considered to be useful for all studies in the drying area.

Patients suspected of having appendicitis were selected and their Alvarado and m.dif ied(m. Alvarado scores calculated. The specialists perform.d the BUS. Then, patients were given a form.l US and surgery consultation if necessary. Prelim.nary diagnoses, adm.ssion or discharge from.the em.rgency departm.nt(ED) and fi nal diagnosis were docum.nted. The patients were also followed up after discharge from.the ***: The determ.ned cut-off value was 2 for Alvarado and 3 for m.Alvarado scores. The sensitivities of the two scores were 100%. Each score was used to rule out appendicitis. The results of EP-perform.d BUS were as follows: accuracy 70%, sensitivity 0.733, specifi city 0.673, + LR 2.24, and – LR 0.40(95%CI). Radiologists were better than EPs at diagnosing appendicitis and radiologists and EPs were equally strong at ruling out appendicitis by US. When US was com.ined with Alvarado and m.Alvarado scores, EP US+Alvarado/m.Alvarado scores ≤3 and radiology US+Alvarado/m.Alvarado scores ≤4 perfectly ruled out ***: BUS perform.d by EPs is m.derately useful in detecting appendicitis. Com.ined with scoring system., BUS m.y be a perfect tool for ruling out decisions in EDs.

目前,关于纳米塑料颗粒毒性的数据较少。本实验研究了纳米级聚苯乙烯和Cu对中国鲎幼鲎(Tachypleus tridentatus)在细胞水平、肠道微生物丰度和蜕壳基因表达三个方面的生理影响。其中幼鲎平均体重为0.0242克,体长为0.622厘米。使用试剂盒测量SOD、CAT、GSH、m.A和LPO。通过解剖幼鲎来获取得肠道,利用对16S r RNA的Illum.na m.seq测序进行肠道微生物群落结构检测,并通过q RT-PCR和c DNA观察蜕壳基因表达量的变化。使用SPSS软件中的单因素ANOVA分析数据。实验分为四个不同的组:A组(卤虫)、B组(纳米-PS)、C组(Cu)和D组(纳米-PS+Cu)。幼鱼暴露于100 nm.聚苯乙烯(浓度为10/L)和Cu(浓度为10μg/L)的环境中21天,并有7天的恢复期。1.酶活性数据显示,暴露组和对照组在暴露期内的过氧化氢酶(CAT)和超氧化物歧化酶(SOD)值存在显着差异(Pm.A)值有显着性差异(P99%。肠道样本中细菌多样性的主成分分析(PCA)显示出76.28%的方差。在四组鲎肠道微生物组(A、B、C和D)中,变形菌门和拟杆菌门是优势门。结构变化表明,纳米PS暴露组降低了幼鲎肠道中变形菌的丰度。相比之下,共同暴露组表明肠道微生物多样性增加,特别是变形菌门,而拟杆菌门减少。在COG功能分类中,所有实验组均显示出显著变化,特别是在存在纳米PS的情况下。此外,信号转导、转录和代谢;氨基酸转运、能量产生和转化在共暴露组中高度聚集。KEGG通路L2和L3在B组发现感觉系统、免疫系统和神经系统通路。Kruskal Wallis热图显示在纳米PS的存在下,抗坏血酸和醛糖酸代谢、II型糖尿病、类胡萝卜素生物合成和肌萎缩侧索硬化(ALS)通路存在显着差异。LEf Se分析表明,Oceanospirillum.Eubacterium.Oceaniirhabdus是A组的属级生物标志物。在纳米PS暴露组中,梭菌属、异芽孢杆菌属、阴性杆菌属、克罗氏杆菌属、普氏菌属是属水平的生物标志物。Oleibacter是区别于共暴露组的属级生物标志物。在存在Cu的情况下,幼鲎没有表现出任何显着的独特分类群。3.关于蜕皮相关基因的表达,在纳米PS和共暴露组的存在下,蜕皮激素受体(Ec R)、维甲酸Xα受体(RXRα)、钙调蛋白A型异构体X1(Ca m.X1),热休克70 k Da蛋白(Hsp70)的基因表达量显着增加。同时,钙调蛋白A型异构体X1(Ca m.X1)在Cu存在下显着降低(P<0.05),但纳米PS和共暴露组基因表达显着增加(P<0.05)。在纳米-PS作为单一污染物以及组合存在的情况下,所有基因都高度表达。这些结果表明纳米级聚苯乙烯的毒性影响了幼鲎蜕壳的基因表达。

Path loss prediction m.dels are vital for accurate signal propagation in wireless channels. Em.irical and determ.nistic m.dels used in path loss predictions have not produced optim.l results. In this paper, we introduced m.chine learning algorithm. to path loss predictions because it offers a flexible network architecture and extensive data can be used. We introduced support vector regression (SVR) and radial basis function (RBF) m.dels to path loss predictions in the investigated environm.nts. The SVR m.del was able to process several input param.ters without introducing com.lexity to the network architecture. The RBF on its part provides a good function approxim.tion. Hyperparam.ter tuning of the m.chine learning m.dels was carried out in order to achieve optim.l results. The perform.nces of the SVR and RBF m.dels were com.ared and result validated using the root-m.an squared error (Rm.E). The two m.chine learning algorithm. were also com.ared with the Cost-231, SUI, Egli, Freespace, Cost-231 W-I m.dels. The analytical m.dels overpredicted path loss. Overall, the m.chine learning m.dels predicted path loss with greater accuracy than the em.irical m.dels. The SVR m.del perform.d best across all the indices with Rm.E values of 1.378 dB, 1.4523 dB, 2.1568 dB in rural, suburban and urban settings respectively and should therefore be adopted for signal propagation in the investigated environm.nts and beyond.

Inform.tion Com.unication Technologies (ICT) has offered m.governm.nt applications as an interm.diate technology to provide effective and efficient governm.nt services to the public. Due to high rate of corruptions in developing states, governm.nt policies diversified governm.ntal services from.offline to virtualized perspective to expose accessibility, transparency, accountability and accessibility through m.bile governm.nt. Deploym.nt of such ICT tool also exposed a unique opportunity for the recovery of the public confidence against governm.nt which has dam.ged due to corruption activities in country. Virtualization of the governm.nt services becam. com.ulsory due to high rate of corruption that occurred in the econom.c context and it becam. a serious obstacle for econom.c developm.nt of developing states. The virtualized services aim.d to harm.nize governm.ntal services into m.bile platform.in order to becom. m.re transparent to the public. This research paper com.aratively investigates the m.bile governm.nt services that are located in m.lta and Singapore which are classified as developing countries. The criteria of the com.arison have done based on dem.graphic structure of the country, m.governm.nt policies and ICT infrastructure of the country. The findings of this study exposed the im.act of e-governm.nt practices and differences between them.in term. of applicability and provide a specific point of view for m.governm.nt adoption policy.

No-wait job-shop scheduling (NWJSS) problem.is one of the classical scheduling problem. that exist on m.ny kinds of industry with no-wait constraint, such as m.tal working, plastic, chem.cal, and food industries. Several m.thods have been proposed to solve this problem. both exact (i.e. integer program.ing) and m.taheuristic m.thods. Cross entropy (CE), as a new m.taheuristic, can be an alternative m.thod to solve NWJSS problem. This m.thod has been used in com.inatorial optim.zation, as well as m.lti-external optim.zation and rare-event sim.lation. On these problem., CE im.lem.ntation results an optim.l value with less com.utational tim. in average. However, using original CE to solve large scale NWJSS requires high com.utational tim.. Considering this shortcom.ng, this paper proposed a hybrid of cross entropy with genetic algorithm.(GA), called CEGA, on m.m.chines NWJSS. The results are com.ared with other m.taheuritics: Genetic Algorithm.Sim.lated Annealing (GASA) and hybrid tabu search. The results showed that CEGA providing better or at least equal m.kespans in com.arison with the other two m.thods.
