Aim of the study: Rosmarinus officinalis (Rosemary) used in Jordanian folk medicine for wound management and treatment. Therefore, the present study was conducted to assess the healing efficacy of both aqueous extract and essential oil of the aerial parts on alloxan-induced diabetic BALB/c mice. Materials and methods: Two full-thickness round wounds were created in the dorsal area of each mouse. Animals were divided into four groups of twenty mice each: untreated normal, untreated diabetic, aqueous extract- (intraperitoneal injection of 0.2. ml at a dose of 10% for 3 days) and essential oil-treated diabetic mice (topical application of 25μl/excision wound, twice a day for 3 days). For 15 days, the wounds were visually observed; blood glucose level, body weight, regenerated granulation tissue weight and the percentage of wound contraction were measured. On days 6 and 15 after wounding, the animals were sacrificed and the histology of wound area was examined. Results: Significant positive differences (p<0.01) between treated and control groups were observed at different aspects of diabetic wound healing process. Reduced inflammation and enhanced wound contraction, re-epithelialization, regeneration of granulation tissue, angiogenesis and collagen deposition were detected in the treated wounds. Conclusions: Results indicated that the essential oil of Rosmarinus officinalis was the most active in healing diabetic wounds and provide a scientific evidence for the traditional use of this herb in wound treatment. However, further scientific verification is required to confirm and assess the range of wound healing potential of essential oils of Rosemary chemotypes. © 2010 Elsevier Ireland Ltd.

Background Little is known about the effect of socioeconomic status on the infestation by head lice in schoolchildren in Jordan. Materials and methods A cross-sectional school-based study was conducted from December 2009 to February 2010. A list of all primary schools in Mafraq governorate was obtained (394 primary schools). Eight primary schools were randomly selected (four male schools and four female schools). Data were collected by five well-trained nurses. Hair was examined for head lice as well as for eggs/nits. Analysis of data was conducted by using SPSS software version 16. The chi-square test was used to assess statistical significance of subgroup differences in the prevalence of infestation, and multivariate logistic regression was used to control for potential confounding. Results Out of 1550 primary schoolchildren screened, 412 (26.6%) were infected with lice, 163 (19.6%) boys and 249 (34.7%) girls. The results showed significant variations in head lice infestation by factors such as gender, age, and socioeconomic variables (family income, father's education, mother's education, number of rooms, number of siblings younger than 15years, frequency of hair washing per week, and bathing per week). There was no significant variation in lice infestation with parents' occupation (P>0.05). Conclusions Socioeconomic status is a major factor influencing the occurrence of pediculosis capitis among schoolchildren in both sexes. Improving standards of living and personal hygiene might significantly reduce pediculosis capitis in schoolchildren in Jordan. © 2012 The International Society of Dermatology.

This study investigated the effect of computer-mediated corrective feedback types in an English as a foreign language (EFL) intact class over time. The participants were 64 English majors who were assigned randomly into three treatment conditions that gave and received computer-mediated corrective feedback while writing (track changes, word processor, and track changes and word processor) and one control group that neither gave nor received writing corrective feedback. Students sat to a pre-test (week 1), immediate post-test (week 8) and delayed post-test (week 12) in writing. Results showed decrease in mean error and mean feedback in students' writing performance related to correcting 11 major error types on immediate and delayed post-tests, indicating that there was a significant effect for feedback type in favour of the group that used a combination of track changes and word processor. There was also a significant effect for the computer-mediated corrective feedback over the control group. Moreover, results showed that both mean error and mean feedback decreased significantly from pre-test to post-test (week 1-week 8), indicating that overall, there was a significant change over time. © 2013 John Wiley & Sons Ltd.

The availability of water and the ability to access are the key questions arising in developing countries including Jordan, which is the fourth poorest country in the world regarding water resources. Renewable energy, especially solar energy, can potentially play a role in the supply of safe water in Jordan Badia, where nearly 80% of the total area of Jordan is Badia, and in most cases these deep wells are far away from the national grid electricity, and in some of these areas there is an important quantity of groundwater at shallow depths. This paper introduces and compares the cost-effectiveness and the Present Value Cost (PVC) for the economic evaluation of power supply for pumping systems in remote areas in Northern Badia of Jordan by two different energy supply systems, photovoltaic systems and diesel engines. Many variables are taken into account such as the fuel prices, and the required investments. The comparison is made for a wide range of variable values, total head, tank capacity, photovoltaic array peak power and pumping requirements. A case study in Tall Hassan station is conducted to analyze the two power supply pumping systems, which are designed to supply drinking water. The results obtained are useful for choosing the best alternative for the power supply of pumping systems in wells in Northern Badia of Jordan. © 2012 Elsevier Ltd. All rights reserved.

This study explored the effect of cooperative learning small group size and two different instructional modes (positive interdependence vs. individual accountability) on English as a Foreign Language (EFL) undergraduate learners' communication skills (speaking and writing) achievement in computer-based environments. The study also examined the effects of disclosing/blinding the participants' identities while interacting around computers on their post-test. The findings of the study revealed that the computer-based environment enabled the participants to blind their identities and reduce their anxiety from face-to-face debate, and so was very helpful in developing their communication skills. The use of the individual accountability mode was quite useful compared with the positive interdependence mode as it enabled all group members to perform their roles significantly. The 5-student group also significantly outperformed other groups of 2-7 members on the post-test communication skills. In conclusion, the findings of this study bring us a step closer to understanding the technique of cooperative language learning and group size. © 2011 Elsevier Ltd. All rights reserved.

For αi,βi positive real numbers for all i=1,...,n, we introduce a new integral operator of analytic functions I αi,βi(f1,...,fn)(z) defined by Iαi,βi(f1,..., fn)(z)=∫0z∏i=1n(fi′(t))αi( fi(t)t)βidt. In this paper, we obtain sufficient conditions for this operator to be in the class N(δ). Furthermore, we determine the order of convexity of Iαi, βi(f1,...,fn)(z). © 2011 Elsevier Ltd.

A novel system with high level of retrieval accuracy has been presented in this paper. Color as one of the most important discriminators in CBIR (content-based image retrieval) is utilized through calculating some of the primitive color features. The indexing of image database is performed with SOM (self-organizing map) which identified the BMU's (best matching units). Subsequently, Fuzzy Color Histogram (FCH) and subtractive fuzzy clustering algorithms have been utilized to identify the cluster for which the query image is belonging. Furthermore, the paper presents an enhanced edge detection algorithm to remove unwanted pixels and to solidify objects within images which ease similarity measures based on extracted shape features. The proposed approach overcomes the computational complexity of applying bin-to-bin comparison as a multi dimensional feature vectors in the original color histogram approach and improves the retrieval accuracy based on shape as compared with the most dominant approaches in this filed of study.

This study investigated the effect of gloss presentation in different text locations whilst participants read EFL texts in a hypermedia environment. Seventy-eight undergraduate EFL learners read and summarized seven texts and completed a vocabulary assessment. The number of propositions recalled in each summary was recorded. The data suggest that reading passages with hypermedia annotations significantly benefits passage comprehension and vocabulary (compared to reading passages with no annotations). The best performance was observed in the condition where glosses were placed after the glossed word. The study also reported large observed score mean differences for the definition gloss type of 3-5-words. © 2011 Elsevier Ltd. All rights reserved.
