Explaining the Increase in the Australian Average House Completion Time:Activity-based versus Workflow-based Approach
Ehsan Gharaie,Ron Wakefield,Nick Blismas
Australasian Journal of Construction Economics and Building , 2010,
Abstract: The Australian house building industry has been facing an increase in the average house completion time in the last decade. This increase in some states is quite dramatic. For instance, Western Australia has faced a 70 percent increase in the average house completion time during this period. This paper uses two planning approaches to explain this; i) the activity-based planning methods and ii) the workflow-based planning methods. In addition, this research investigates the strengths and weaknesses of these two planning approaches in explaining the behaviour of the house building industry. For this purpose, a national case study and five state case studies including Victoria, Western Australia, New South Wales, Queensland and South Australia have been used. The data related to the key parameters have been collected and their correlation with the average house completion time has been investigated. These key parameters include the average house floor area, the number of house completions and the number of houses under construction. The reasons for the increasing trend of the average house completion time have been postulated in all case studies. According to this research, the increase in the average house completion time cannot be explained using activity-based planning methods. In contrast, by using workflow-based planning methods, it has been shown that the average house completion time is correlated with the number of houses under construction. This paper shows that the average completion time is influenced directly by the workflow in the house building industry and that workflow planning should be the basis for the house building industry planning.
A COMPARISON OF CLOMIPHENE CITRATE AND SEQUENTIAL CLOMIPHENE CITRATE PLUS HUMAN MENOPAUSAL GONADOTROPIN FOR USE IN CONJUNCTION WITH INTRAUTERINE INSEMINATION

Abstract: There are currently many different protocols in use for controlled ovarian hyperstimulation (COH), but the optimal method has not yet been determined. To compare the outcome of COH using clomiphene citrate (CC) versus CC plus human menopausal gonadotropin (hMG) in conjunction with intrauterine insemination (IUI), we studied 117 infertile couples . IUI with CC was used in 92 cycles (group A) and IUI with CC plus hMG was used in 66 cycles (group B). Data analysis demonstrated no significant difference between the two groups with respect to patients’ age, duration and type of infertility, prior COH and endometrial thickness and pattern. Group A had a little longer follicular phase length than group B. Pregnancy rate for group A and B were 6.52% and 12.12%, respectively (P= 0.22). Endometrial pattern and thickness had no impact on pregnancy rate. There were no multiple gestation and obvious hyperstimulation syndrome. For patients undergoing controlled ovarian hyperstimulation with IUI, CC plus hMG protocol yields higher pregnancy rate than one using CC, although this difference was not statistically significant because of limitation of number of cycles.
A New Algorithm for Optimum Design of Mechanical Draft Wet Cooling Towers
A. Ataei,M.H. Panjeshahi,M. Gharaie
Journal of Applied Sciences , 2009,
Abstract: The present study describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. The design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. The design model incorporated the cooling tower factors to achieve the optimum design. The main factors included: the diameter of the water droplets, the liquid to gas mass ratio, the height of rain zone, packing zone and spray zone, the air and water velocity inside the tower and the frontal area. Once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables. The optimization model is validated against a sample problem. The suggested design algorithms of cooling tower are computed using Visual Studio.Net 2003 (C++).

Iranian Journal of Psychiatry , 2012,
Abstract: Objective: Children with attention-deficit / hyperactivity disorder (ADHD) react explosively and inappropriately to emotional stimuli. It could be hypothesized that these children have some impairment in attending to emotional cues. Based on this hypothesis, we conducted this study to evaluate visual directions of children with ADHD towards paired emotional scenes.Method: thirty boys between the ages of 6 and 11 years diagnosed with ADHD were compared with 30 age-matched normal boys. All participants were presented paired emotional and neutral scenes in the four following categories: pleasant-neutral; pleasant-unpleasant; unpleasant-neutral; and neutral – neutral. Meanwhile, their visual orientations towards these pictures were evaluated using the eye tracking system. The number and duration of first fixation and duration of first gaze were compared between the two groups using the MANOVA analysis. The performance of each group in different categories was also analyzed using the Friedman test.Results: With regards to duration of first gaze, which is the time taken to fixate on a picture before moving to another picture, ADHD children spent less time on pleasant pictures compared to normal group ,while they were looking at pleasant – neutral and unpleasant – pleasant pairs. The duration of first gaze on unpleasant pictures was higher while children with ADHD were looking at unpleasant – neutral pairs (P<0.01).Conclusion: based on the findings of this study it could be concluded that children with ADHD attend to unpleasant conditions more than normal children which leads to their emotional reactivity.
Honey with Coffee: A new finding in the treatment of Persistent Postinfectious Cough

Iranian Journal of Otorhinolaryngology , 2011,
Abstract: Introduction: Persistent postinfectious cough (PPC) is a cough that persists longer than 3 weeks or perhaps for many months after a common cold or an upper respiratory tract infection (URTI). PPC has poor response to routine treatment modalities, so it can be a vexing problem for the patient and the physician alike. Our hypothesis was that honey and/or coffee have some beneficial effects in the treatment of PPC. The aim of this study was to evaluate the therapeutic effects of coffee and/or honey in the treatment of patients with PPC. Materials and Methods: This was a double blind randomized clinical trial, conducted on adult patients during a 6-year period from 2003 to 2009. Included in this study were 84 adult participants that had experienced PPC longer than 3 weeks. All of them had the history of several referrals to different physicians and despite treatment, their cough had persisted. Patients with other causes of chronic cough, or systemic disease or with abnormal routine laboratory tests were excluded. All the included 84 participants were distributed into three groups. For all the participants, a jam-like paste was prepared. Each 600 grams of the product consisted of "70 grams original instant coffee" in the first regimen, "500 grams of honey" in the second regimen and "70 grams of instant coffee plus 500 grams of honey" in the third regimen. These participants were told to dissolve 25 grams of the prescribed product in about 200 CC of warm water (under 60o C), and drink this solution every 8 hours for one week. All the participants were evaluated before and at the end of the first week of their treatment, to measure the frequency of their cough. In addition they were under observation for the first month. Results: Comparing the effectiveness of all three treatment regimens, this study found "honey with coffee" as the most effective treatment modality for PPC (P
