A critical and realistic evaluation of natural dyeing highlighting its metal toxicity of mordants has been reported. From the eco-friendly point of view, this research work aimed to investigate the trace metal ions extracted from the dyed mordanted natural fabrics, i.e. (wool, silk and cotton) using cochineal natural dye and FeSO4 and CuSO4 as mordants. The mordanting was performed throughout two mordanting techniques, while the trace metal ions were extracted using artificial perspiration solution for different extraction times (2, 4 and 24 hours). The unmordanted and mordanted dyed samples were characterized through comparing the ions amount in the eluted solution with those approved by the Oeko-Tex standards. In addition, the UPF of the tested samples was also evaluated. Finally, the color strength (K/S) and color parameters of the dyed samples alongside with the color fastness of the artificially light aged samples were assessed.
This study evaluates the correlations between academic performance and the reading prowess of executive MBA students in South Africa. The analysis peruses reading ability and academic performance of the first-year students from 2012 to 2015 of an Association of MBAs business school. A total of 63 students voluntarily participated in having their reading ability tested. The results showed that South African MBA students do not read as well as their international counterparts. Strong correlations were identified between the reading ability and the academic performance of South African MBA students. The analyses showed that not only does good reading ability correlate positively with academic performance, but that poor reading ability does also correlate positively with poor academic performance. In addition, the study found that although academic modules may differ in nature (such as financial versus theoretical content), they are strongly positive correlated, indicating that academic performance in one module should indicate success in other modules.
Objective: The influence on therapeutic outcomes of wide surgical resection of brain metastasis (BM) including tumor cells that microscopically infiltrate adjacent brain parenchyma, with clean surgical margins confirmed by intraoperative margin biopsy is not known. This study was carried out to clarify the therapeutic impact of these resections.\nMethods: From June 2002 to April 2014, 90 patients (66 men and 24 women; mean age: 56.7 years) underwent surgical resection for BM. In 47 patients (group A), we undertook microscopically complete resection, including microscopic infiltrative tumor cells adjacent to the brain parenchyma, with pathologically clean surgical margins confirmed during surgery for BMs in a noneloquent area. In 43 patients (group B), we undertook gross complete resection without removal of neighboring brain parenchyma due to eloquent location. The two groups were compared for survival, and local and distant recurrence.\nResults: Mean follow-up duration was 18.6 months; 71 patients (78.9%) died during follow-up. Median survival was 13.1 months in group A and 12.1 months in group B (p = 0.309). One-year and two-year local recurrence were 21.2% and 25.8%, respectively, in group A, and 65.2% for both in group B (p = 0.000). One-year and two-year distant recurrence rates were 46.3% and 57.2% in group A, respectively, and 33.2% for both in group B (p = 0.140). \nConclusion: These results suggested that wide surgical resection of BM including tumor cells infiltrating adjacent brain parenchyma with confirmed clean surgical margins resulted in better local control.
The aim of this study is to test the impact of accounting information system utilization on the transparency effectiveness through the internal controlling in Jordanian Banks. The questionnaire has been used as a tool to collect data base for the study’s variables. It was distributed on a convenience sample consisting of 160 employees in Jordanian Commercial Banks. The researcher used Statistical Package for the Social Sciences SPSS to analyze and test study hypothesis. \nThe results of the study have revealed that accounting information systems have positive impact on transparency through internal control. But this effect is very low, and internal control has positive direct impact on transparency. On the basis of the study’s results, the researcher has suggested many recommendations to Jordanian Commercial Banks in order to improve the role of accounting information systems to increase transparency.
This study has been conducted to evaluate the effect of different feed restriction regimes on some behavioral traits of broilers by using Multidimensional Scaling Technique. 60 one day old Ross 308 broiler chicks were randomly distributed into three groups. Each group included 10 males and 10 females. Three different feeding regimes namely AD: (Birds were fed ad libitum), FR: ( of AD feed removed from 11 p.m. to 7 a.m. during a day), and NF:(feed removed from 9.00 a.m. to 15.00 p.m. and then the birds were fed ad libitum). Results of Repeated Measurement ANOVA and Multidimensional Scaling Technique indicated that the feed restriction regimes had significant effect on body weight gain, feed efficiency, mortality, and slaughter weight. Feed restriction regimes had also significant effect on behavioral traits. Especially, the birds in NF groups were more active than the birds in the AD and FR groups. And this case was more obvious for males. It was also observed that the feed restrictions significantly reduced slaughter weight, mortality rate, and fat percentage in the breast meat.
Vehicular Ad Hoc Network (VANET) is a growing field of Intelligent Transportation System (ITS). It holds a significant use in managing the emergencies and providing infotainment in a moving vehicle. In VANET due to the high mobility of vehicle and rapid topology change, finding a short and stable route is a complex problem. In this paper, we proposed a routing protocol to find a short and stable route: Bacterial Foraging Optimization for Zone Based Routing (BFOZBR) protocol for VANET. This BFOZBR protocol uses two techniques to handle the routing problem. The first technique used is Zone Based Routing (ZBR) that divides the network into zones, and nodes distributed into zones on the basis of similar characteristics like velocity, direction, and position, that increases the stability. The second technique used is bacterial foraging optimization (BFO) to find the best route in a short period. We carried simulation for two cases. In the first case, we considered the different transmission rate at fix velocity. In the second case, we considered different node velocity at fix transmission rate. The simulation results of BFOZBR analyzed and compared with other routing protocol Fuzzy Zone Based Routing (FZBR) protocol. We evaluated routing performance by four performance parameters: average delay, packet drop ratio, packet delivery ratio, and overhead. We selected theses parameters because they provide Quality of Service (QoS). Simulation results revealed that the packet delivery ratio is high, and the packet drop ratio is low in BFOZBR compared to FZBR, which indicates that the discovered route is stable. The results also revealed that end-to-end delay is also less in BFOZBR compared to FZBR, which indicates that the discovered route is a short route.
