STR-862: APPLICATION OF 4D AND 5D BIM IN COLD-FORMED STEEL RESIDENTIAL BUILDINGS

Traditional residential building systems are not sufficient to produce the required number of housing units needed every year to solve the current housing problem in many countries. To meet such a challenge, it is necessary to explore the latest construction technologies, and to create innovative building systems that have the potential to bring high-performance affordable housing within reach of new markets. Light (cold-formed) steel (CFS) framing systems have proven to be a worthy alternative to traditional systems. Recent advances in the application of Building Information Modeling (BIM) into the Architecture-Engineering-Construction industries present an additional mean to further enhance the efficiency of CFS projects. This paper presents a BIM based integrated approach for project scheduling and cost estimating of cold formed steel residential buildings. The approach integrates the basic 3D BIM model with the construction management tools used for project scheduling and cost estimation to produce a 4D BIM and 5D BIM models that can be used to enhance the project efficiency in both the design and construction phases. The developed models facilitate communication among all project participants and support project management in effectively planning on-site construction activities. A case study is presented to demonstrate the methodology

An explicit representation, a matrix recurrence relation for the Hermite-Hermite matrix polynomials are given and differential equations satisfied by them is presented. A new expansion of the matrix exponential for a wide class of matrices in terms of Hermite-Hermite matrix polynomials is proposed

Some Comparative Anatomical and Histological Studies on the Laryngeal Cartilages of Buffaloes, Camels and Donkeys

Comparative studies concerned the upper air ways of domestic animals are few. So this study was carried out to compare between the larynx of buffaloes, camels and donkeys. The present investigation was carried out on 39 larynxes, 13 larynxes (7 males, 6 females) of each species. Ten heads from each species were used for gross anatomical study; the remained three heads were used for the histological study. Results revealed that, the laryngeal cartilages of the three species were consisted of three single cartilages; the thyroid, the cricoid and the epiglottis, and two paired cartilages; the arytenoid and the corniculate. The cuneiform cartilages were paired cartilages present only in the larynx of the donkey. Thyroid, arytenoid and cricoid cartilages were of hyaline type, while the epiglottis, cuniform and corniculate cartilages and the vocal process of the arytenoid cartilage were of elastic type. The laryngeal epithelium of aditus laryngis, greater part of epiglottis and vocal folds was lined by non-keratinized stratified squamous epithelium. The remained parts of laryngeal epithelium from base of epiglottis and entire parts caudal to vocal folds were lined by pseudostratified columnar ciliated epithelium with goblet cells. The laryngeal glands of lamina propria were of mixed types in buffaloes and donkeys but in camels it was pure mucous glands. This study will fill a gap in the field of comparative anatomy and help other clinical investigation applied on these animals

Some Comparative Anatomical Studies on the Laryngeal Muscles and Cavity of Buffaloes, Camels and Donkeys

The aim of this study was to compare between the laryngeal muscles and cavity in buffaloes, camels and donkeys. A total of 30 larynxes (10 larynxes from each species) were subjected to study. In the three species, the laryngeal muscles were similar to those of other domestic animals, but the hyoepiglotticus muscle of camel was remarkably longer. Although the thyroarytenoideus muscle was undivided in the buffalo and camel, the slightly deeper lateral ventricle in camel, allowed the muscle anterior part to be covered with mucous membrane forming the vestibular fold. The laryngeal cavity of donkey was characterized by the presence of lateral laryngeal saccule that located between the two separate parts of thyroarytenoideus muscle, the vestibular and vocal muscles; the presence of two small pouches on both sides of median laryngeal recess, and the cuneiform tubercle, which was a mucosal elevation that covered the cuneiform process. This study will fill a gap in the field of comparative anatomy and help other clinical investigation applied on these animals

Comparative Anatomy of the Nasal Cavity in Buffaloes, Camels and Donkeys.

The aim of this study was to reveal the comparative anatomy of the nasal cavity in buffaloes, donkeys and camels. It was carried out on 30 heads of apparently healthy adult animals, 10of each species. Heads were fixed and used for gross and cross sectional anatomy. The study provided information about the peculiarities of nasal anatomy in each species. The conchal arrangement was greatly different in camels, while that of buffaloes and donkeys were similar to other ruminants and equine. In camels, the nasal conchae were condensed in the caudal two thirds, the ventral nasal concha was shorter and twisted and the alar and basal folds were raised from a common extension. Camels have a vestibular pouch known as lateral nasal diverticulum. It was a cylindrical tube anatomically different from the nasal diverticulum of donkeys and other equine. The cartilaginous skeleton of narial aperture was reduced in donkeys and camels. Moreover, the rostral portion of nasal septum in camels was formed of muscles instead of cartilage. In the three species, vomeronasal organ and dorsal and ventral swelling bodies were present on both sides of the nasal septum. However, in camels the vomeronasal organ was notably longer and wider. In conclusion, the anatomy of camel nasal cavity in contrast to other domestic animals was presented interesting anatomical features similar to those of proboscis-bearing mammals

Trip Attraction Rates of Banking Services in Developing Countries' Cities

There is a lack of studies on trip generation rates related to land use activities in developing countries. The absence of trip rates makes transportation planners use rates listed in the Institute of Transportation Engineers (ITE) Trip Generation Manual, which may lead to unrealistic results. The study aims to determine trip attraction rates for banking services in Zagazig city, Egypt, and evaluate the factors affecting the attracted trips to the banks. The study has designed and implemented a comprehensive data collection and analysis program. The study sample contained nine banks. The study has conducted field surveys that counted the total number of persons entering/exiting the bank under investigation and the generated traffic volume of the adjacent street. The trip rates have been established in terms of independent variables, i.e., gross floor area, the total number of employees, and the number of tellers for different types of banks. Findings showed that average trip attraction rates for public banks were higher than for private banks. There was a strong relationship between trip attractions and the total number of employees at public banks. The most representative factor of private banks' trip attractions was the number of tellers. Doi: 10.28991/CEJ-2023-09-02-07 Full Text: PD

Effect of Counteracting Lifestyle Barriers through Health Education in Egyptian Type 2 Diabetic Patients

BACKGROUND: Egypt is among the world top 10 countries in diabetes prevalence. It is the first country among the MENA region. Healthy lifestyle education and support help people with diabetes to improve health outcomes. Many physical and psychological barriers can hinder patients from following a healthy lifestyle. AIM: This study aimed to examine the effect of lifestyle modification educational sessions in helping Egyptian patients to overcome main barriers of diabetes self-management through improving nutritional behaviours, physical activity, medication compliance, and blood glucose monitoring. METHODS: A cohort study included 205 patients with type 2 diabetes. Baseline assessment of patients' lifestyle behaviours and barriers using personal diabetes questionnaire of Louisville University, with both anthropometric and blood glucose assessment. Interventional lifestyle health education was provided weekly through multiple integrated techniques, followed by a post-intervention assessment to evaluate the effect of the health education sessions. Statistical analysis was done to identify any statistically significant difference before and after the health education intervention. RESULTS: There was a significant improvement of the post-education mean scores of the studied behaviours when compared with the pre-education scores of the participants’ behaviours (p &lt; 0.001). There was also a significant reduction in the barriers facing patients to diabetes self-management including nutritional barriers (P &lt; 0.001), medication compliance barriers (P &lt; 0.001) with a percent change (43%), physical activity barriers (p &lt; 0.001), and blood glucose monitoring (p &lt; 0.001) with a percent change (44%).There was a statistically significant positive correlation between improvement of medication compliance (P = 0.027), blood glucose monitoring(P = 0.045), and glycated haemoglobin of the study participants CONCLUSION: lifestyle modification education of type 2 diabetic patients can overcome the main barriers of following a healthy lifestyle and improve their anthropometric measures and blood glucose level

Curative and protective potentials of Moringa oleifera leaf decoction on the streptozotocin-induced diabetes mellitus in albino rats

The present study was designed to investigate the protective, and curative potentials of Moringa oleifera (MO) leaves powder against streptozotocin (STZ) induced type 1 diabetes mellitus (T1DM) in rats. Fifty adult Wistar male albino rats were randomized and divided into five equal groups: The normal control group, the Moringa group, The diabetic group, the therapeutic group, and the diabetic rats (3 days after STZ injection) were received-MO-for successive 8 weeks and the prophylactic group, the rats were received-MO-for 2 weeks before STZ induced diabetic rats and lasted for 8 weeks. The protective or treated oral administration of 1 ml freshly prepared aqueous leaf decoction of-MO-revealed a significant upregulation of the mRNA expression of PDX-1, Ngn3, VEGF, IGF-1, and GLUT-2. Additionally, it induced a significant downregulation of FBG level compared to that of the diabetic group, a significant reduction in MDA level and a significant elevation in the TAC level. Furthermore, the histopathological observations of pancreas, liver, and kidney tissues affirmed the improvement in treated and prophylactic groups compared to STZ-diabetic groups, and the improvement in the prophylactic group was more distinct than the treated group. MO-aqueous leaf extract can treat and protect against STZ-induced T1DM; via its antioxidant action (increase the TAC and decrease MDA). Thus, it has the potential for utilization as a prophylactic against diabetes
