BIM as Evaluation Tool for Existing Building Energy and Quantities Takeoff

Information technology and its application have resulted in enormous development in the construction industry during the last decade. The main reason behind this evolution was the incorporation of Building Information Modeling (BIM) to be an inefficient construction approach. BIM is now globally considered to be the tool of transforming the construction process to new era. It is also considered as a good tool for the whole project lifecycle. The aim of the present study is to clarify how BIM can be used in after project construction within uncertainty and risky environment such as document losses and unrecorded change orders. Interviews with project team, project site photography, collecting the available schemes and documents were the approaches used in this work to re-build the projects models. The results obtained from this work show that the knowledge and expectations of BIM within existing building have an admirable achievements for construction industry. Furthermore, BIM approach used in this work made more progress in the implementation of BIM as a rehabilitation and renovation tool in civil projects. The conclusions from this study reflect high correlation between the quantities take off with what as-built constructed, more than the traditional approach. The glamorous lessons derived from BIM implementation for the case study is; working with a model in which all project team feel comfortable and harmonic, will ensure enough resources to make the model updated and ought to lead to a minimum conflict within the model or what traditionally called  “project documents”

Evaluating Windows Vista user account security

In the current Windows version (Vista), as in all previous versions, creating a user account without setting a password is possible. For a personal PC this might be without too much risk, although it is not recommended, even by Microsoft itself. However, for business computers it is necessary to restrict access to the computers, starting with defining a different password for every user account. For the earlier versions of Windows, a lot of resources can be found giving advice how to construct passwords of user accounts. In some extent they contain remarks concerning the suitability of their solution for Windows Vista. But all these resources are not very precise about what kind of passwords the user must use. To assess the protection of passwords, it is very useful to know how effective the widely available applications for cracking passwords. This research analyzes, in which way an attacker is able to obtain the password of a Windows Vista PC. During this research the physical access to the PC is needed. This research shows that password consists of 8 characters with small letter characters and numbers can easily be cracked if it has know usual combinations. Whereas a Dictionary Attack will probably not find unusual combinations. Adding captel letter characters will make the process harder as there are several more combinations, so it will take longer time but is still feasible. Taking into account special characters it will probably take too long time and even most Dictionary Attacks will fail. For rainbow tables the size of the table has to be considered. If it is not too big, even these small passwords cannot be cracked. For longer passwords probably the simplest ones, small letter characters and numbers, can be cracked only. In this case brute force takes too long time in most cases and a dictionary will contain only a few words this long and even the rainbow tables become too large for normal use. They can only be successful if enough limitations are known and the overall size of the table can be limited

Seatbelts and road traffic collision injuries

Modification of seatbelts and their legislation played an important role in reducing morbidity and mortality of occupants in road traffic collisions. We aimed to review seatbelt development, its mechanism of action and its effects. Seatbelts reduce injury by preventing the occupant from hitting the interior parts of the vehicle or being ejected from the car. We have made a linear regression correlation between the overall seatbelt compliance and road traffic death rates in 46 high income countries to study the relationship between seatbelt use and mortality. There was a very highly significant negative correlation between the seatbelt compliance and road traffic death rates (R = - 0.77, F = 65.5, p < 0.00001). Seatbelt-related injuries include spinal, abdominal or pelvic injuries. The presence of a seatbelt sign must raise the suspicion of an intra-abdominal injury. These injuries can be reduced if seatbelts were applied correctly. Although seatbelts were recognized as an important safety measure, it still remains underused in many countries. Enforcement of seatbelt usage by law is mandatory so as to reduce the toll of death of road traffic collisions

Effect of irrigation methods and tillage system, seed level on water use efficiency and wheat (Triticum aestivum L.) growth

Afield trial was conducted at Al- Hashimya area, Babylon district, Iraq during the growing seasons 2016-2017 and 2017-2018 to investigate the effect of some agronomic practices viz. irrigation system ( sprinkler irrigation (I1) and surface irrigation (I2) which occupied the main plots; tillage system (Zero tillage (T0), minimum tillage (T1) and deep tillage (T2) which occupied the subplot ); and seeding rates (120 Kg ha-1( S1), 180 Kg ha-1(S2),240 Kg ha-1 (S3)and 300 Kg ha-1 (S4) which occupied the sub _ subplots on biological yield, harvest index, water _use efficiency, water consumptive use, crop coefficient of bread wheat (Triticum aestivum L.). Results indicated that biological yield was increased in both seasons by 9 and 10%, respectively, following the application of sprinkler irrigation. This may be due to the increased water _use efficiency by 29 and 32% in both seasons, respectively, as influenced by sprinkler irrigation. However, sprinkler irrigation did not affect the harvest index in both seasons. Similarly, minimum tillage increased the biological yield by 10.6,10.2,11.8 and 3.4 % over zero _ tillage and deep tillage in both seasons, respectively. However, the tillage system had no significant effect on the harvest index in both seasons. The seeding rate (240 Kg ha-1) increased the biological yield by 15.1 and 16.0 % over the lowest seeding rate (S1 120 Kg ha-1) with no significant effect on the harvest index in both seasons, respectively. The exciting result that the application of sprinkler irrigation (I1) decreased the consumptive use mm. Season in both seasons and consequently the crop coefficient(Kc) was decreased at tillering, elongation, flowering and maturity stages in both seasons. It can be concluded that the application of sprinkler irrigation under the minimum tillage and using the seeding rate 240 Kg ha-1 has increased the biological yield via increased water – use efficiency and decreased both consumptive use and crop coefficient

With this purpose, the model parameters results, based on droplet break-up model proposed by Reitz and Diwakar [1] and momentum flux calculations are performed. The parameters that are used in the droplet break-up model are stored in the code as properties. These properties are saved in every computation cell. The parameters are Weber number, break-up time and stable droplet diameter. The numerical simulation is implemented as Eulerian-Eulerian approach. The spray moments theory is used for the liquid phase. Finally the study is implemented in a conceptual model to investigate the possible benefits of the droplet break-up model. A good agreement for the numerical results are compared with the experimental data for the spray tip penetration

Prevalence of overactive bladder symptoms and urinary incontinence in a tertiary care hospital in Egypt

Background: The current study aims to estimate the prevalence of Overactive bladder (OAB) and urinary incontinence (UI) among women attending Assiut Woman's Health Hospital. Additionally, to explore the impact of UI and OAB on The Quality of Life (QOL) of women.Methods: A population-based survey included participants aged 18 years and older selected from Assiut Woman's Health Hospital and received The Bristol Female Lower Urinary Tract Symptoms Questionnaire (BFLUTSQ). OAB was defined in to two versions using the international continence society (ICS) definition of 2002 as either urgency sometimes or more alone (OAB1) or urgency sometimes or more with frequency more than eight times per day and /or nocturia once or more per night (OAB2). Incontinence and other LUTS were positive if answer scores ≥2 to BFLUTSQ question for incontinence and other LUTS.Results: The total prevalence of OAB was 39.0% (351 women). The prevalence of OAB dry and OAB wet was 26% (234 women) and 13% (117 women), respectively, which suggested that 66.7% suffer from OAB dry and 33.3% suffer from OAB wet. The prevalence of dry OAB is significantly higher than wet OAB. The overall prevalence of UI was 22.2% (201 women). The prevalence of stress UI, urge UI and mixed UI was 5.7%, 5.1% and 11.4%, respectively.Conclusions: OAB symptoms and UI are highly prevalent. Furthermore, both of them have severe effects on daily and sexual life as well as being related to psychological symptoms such as anxiety and depression

Clinical audit of neonatal care in Assiut Women's Health Hospital, Egypt

Background: The current study aims to auditing the current care of healthy full term newborns in the delivery room and identify the gap between the current practice and ideal practice in Assiut Women's Health Hospital, Egypt.Methods: The current study was a clinical audit carried out in Assiut Woman Health Hospital, in the period from 1 September 2016 to 28 February 2017.The study included all newborns delivered in the delivery word of gestational age after 37 week. We excluded all Preterm babies, those with congenital anomalies, pregnant women with medical disorders and multiple pregnancies. In the present work all data was collected prospectively through direct personal patient contact, direct observation of care givers, patient interactions and attitudes, from the clinical records and then recording the data in special check sheet. All basic criteria of the study participants as age, parity, gestational age at delivery and type of delivery were obtained. The neonatal gender, weight, heart rate and respiratory rate were checked. Audit criteria were selected according to the WHO 2015 and AAP 2010-2015 guidelines.Results: The study included 800 women; the mean age of the women was 26.52±5.70 years. The mean parity was 1.78±1.85. The mean gestational age at delivery was 38.81±0.96 weeks. As regard the type of delivery, 54.1% of women were delivered by cesarean section. Calling neonatologists occurred in 67.9% of deliveries. The mean birth weight was 3.17±0.39 kilograms. Nearly half of them (52%) were males.Conclusions: Application of the guidelines of the neonatal handling is important for optimum care to the neonates. Re-audit the steps of the handling is important to discuss whether practice has improved or not in our tertiary hospital

Geriatric fall-related injuries.

Background: Falls are the leading cause of geriatric injury. Objectives: We aimed to study the anatomical distribution, severity, and outcome of geriatric fall-related injuries in order to give recommendations regarding their prevention. Methods: All injured patients with an age 65 60 years who were admitted to Al-Ain Hospital or died in the Emergency Department due to falls were prospectively studied over a four year period. Results: We studied 92 patients. Fifty six of them (60.9%) were females. The mean (standard deviation) of age was 72.2 (9.6) years. Seventy three (89%) of all incidents occurred at home. Eighty three patients (90.2%) fell on the same level. The median (range) ISS was 4 (1-16) and the median GCS (range) was 15 (12-15). The lower limb was the most common injured body region (63%). There were no statistical significant differences between males and females regarding age, ISS, and hospital stay (p = 0.85, p = 0.57, and p = 0.35 respectively). Conclusion: The majority of geriatric fall-related injuries were due to fall from the same level at home. Assessment of risk factors for falls including home hazards is essential for prevention of geriatric fall-related injuries
