Comparing The Pull Out Resistance Of Two Typs Of Posts Used In restoration of severely damaged primary anterior teeth )A Comparative In Vitro Study.(
No full textBackground: severely damaged primary anterior teeth that require pulp therapy present a high-risk of failure due to the loss of tooth substance resulting from pre-existing decay and endodontic therapy itself. The ideal post material should have physical and mechanical properties that are similar to those of dentin . Another concern in restoring endodontically treated primary teeth is the need to find a material that can resorb in a similar way to natural tooth structure as a part of the exfoliation process allowing normal eruption of permanent successors . Accordingly there is no such material other than dentine itself.The introduction of Biological dentine posts offered an excellent alternative for restoring such teeth. The aim of the current study was to assess the effect of using dentine posts on the Pull Out resistance of endodontically treated primary anterior teeth in comparison to composite posts.
Materials and methods: A sample of 30 primary anterior teeth was collected from the outpatient clinic of Pediatric Dentistry Department, Faculty of Dentistry,Damascus University. 15 freshly extracted permanent teeth with single root were also collected from the outpatient clinic of Maxillofacial Surgery Department, Faculty of
Dentistry,Damascus. University. The roots of the permanent teeth were used to prepare 30 dentine posts using CAD-CAM machine. After receiving proper endodontic treatment, the primary teeth were divided into two groups (15 teeth in each group). The first group was restored with dentine posts, and the second group was restored with composite posts 3 mm in length for both groups. Pull Out resistance testing was performed using Testometric machine.
Results: The results were recorded.descriptive statistics were performed and the data were analyzed at 95% confidence interval using independent t-student test. There were no statistically significant differences in Pull Out resistance between the two groups. But Dentin posts showed increased in Pull Out resistance (156,7) N more than composite posts (149,7) N.
Conclusion: Dentin posts showed increased in Pull Out resistance (156,7) N more than composite posts (149,7) N. Therefore, the use of dentin posts as intra-canal retention in primary anterior teeth is a successful alternative for composite posts

Rotating Burlap for Improved Solar Still Performance: An Experimental Investigation
Get PDFThis experimental study investigates the performance of a modified solar still that utilizes a rotating burlap cloth to enhance water evaporation and productivity. Conducted in Tanta, Egypt within a hot desert climate, the system was designed with a 31° angle to maximize solar energy absorption. A 12V DC motor was employed to maintain continuous rotation of the burlap, ensuring consistent contact with the water surface and promoting enhanced evaporation. The modified system achieved a peak water temperature of 89.4°C, resulting in a total water output of 1.547 liters per day, which translates to 4.56 liters per square meter per day—an improvement of 14% compared to conventional solar stills. With an efficiency of 44.7%, the system performed at high levels relative to typical solar stills, which generally operate within the range of 30%–50%. In hot summer months in the same region, where ambient temperatures can reach 40°C, the system\u27s productivity could increase to 6 liters per square meter per day, reflecting a potential 30% enhancement over conventional designs. This innovative approach combines relatively low cost with high productivity, offering a practical solution for solar desalination. The findings demonstrate that this design represents one of the most efficient and cost-effective systems for water production in Hot desert climates (BWh), capable of providing significant water output under optimal conditions
Techniques for Controlling Saltwater Intrusion in Coastal Aquifers
Get PDFGroundwater is a significant freshwater source due to rising water demand for agriculture, industry, rapid population growth, and home usage; however, coastal groundwater is at risk of pollution from seawater intrusion due to intensive pumping.
Heavy extraction of groundwater to meet rising demands has resulted in lower groundwater tables and less seaward freshwater flow. As a result, saltwater spreads further inland, threatening fresh groundwater supplies. Saltwater intrusion refers to the introduction of saltwater into an aquifer system. Around the world, there are several coastal and deltaic regions in which seawater intrusion occurs. Underground water supplies are made worthless when seawater flows inland to production wells. The most frequent cause of contamination in coastal aquifers is seawater intrusion. In order to safeguard the resources of groundwater in coastal aquifers, a variety of techniques have been employed to mitigate saltwater intrusion. A brief amount of research has focused on preventing seawater intrusion to safeguard coastal areas\u27 groundwater supplies. To manage coastal aquifers and mitigate seawater intrusion, withdrawal procedures must be carefully planned. Thus, it is vital to effectively manage seawater intrusion to prevent the depletion of groundwater supplies.
New techniques for controlling seawater intrusion are given and discussed in detail. The SEAWAT code was used here to investigate the effectiveness of different controlling techniques to mitigate seawater intrusion. The outcomes of this research can be implemented to achieve sustainable development of groundwater resources in coastal aquifers
Evaluating LiDAR Technology in iPhone Mobiles for 2D Mapping Applications
Get PDFAbstract- LiDAR (Light Detection and Ranging) technology has revolutionized mapping applications, offering enhanced precision and accuracy in spatial data collection. The integration of LiDAR technology in the latest iPhone models, beginning with the iPhone 12 Pro, has introduced new capabilities for 2D data measurement and plan creation directly on the mobile device. The iPhone 12 Pro and 12 Pro Max models support LiDAR techniques within their mobile phone cameras, enhancing the performance of various applications such as Measurements and Photos. LiDAR operates by emitting pulsed light waves into the surrounding space, which bounce off nearby objects and return to the sensor, enabling the phone to calculate the distance traveled by each pulse and map the surrounding features. In this investigation, the LiDAR feature in the iPhone 12 Pro Max was utilized to measure the 2D floor plan of a small building. Interior scanning was conducted by moving the iPhone around the space approximately 3 to 6 meters away from the walls. The same building was surveyed again using a precise Leica total station instrument to obtain the coordinates of the partition corners. The iPhone LiDAR scanner requires only 4 minutes compared to the 2-hour total station survey mission time. The point cloud data from the iPhone LiDAR scan was exported and processed to generate a 2D floor plan, which was subsequently compared to the plan derived from the total station measurements. The comparison revealed that the iPhone LiDAR provided satisfactory horizontal measurements, displaying root mean square errors of ± 0.08 meters for side lengths and ± 0.28 square meters for areas. Minor differences were observed in the measured angles, with a root mean square error of ± 2.02 degrees. Overall, the researchers concluded that the iPhone LiDAR technology can provide valuable measurements, especially for a smaller-scale projects, with ease, cost-effectiveness, and rapidit
Dwellings Occupant Behaviour and Electric Heating Consumption: Sensitivity Analysis and Potential Savings
Get PDFA building\u27s heating consumption is affected by a lot of things, including the weather, the building\u27s envelope, and the heating system. Furthermore, a crucial component impacting dwelling electrical consumption is the behaviour of occupants. Analysing the impact of occupant behaviour on electric heating consumption in dwellings located in temperate oceanic climates is the focus of this study. By surveying the existing literature on the topics of building energy simulation and occupant behaviour, this study was able to determine the strengths and weaknesses of earlier investigations, as well as the research technique. A case study of a semi-detached house in Galway, Ireland, is used to apply the methodology, which includes building energy modelling, sensitivity analysis using the Standardized Regression Coefficient, and estimates of energy savings. The study\u27s overarching goal is to use DesignBuilder to investigate occupant-related situations and evaluate prospects for energy savings. According to the sensitivity analysis, the main parameters that affect electric heating usage are the number of occupants and the heating setpoint temperature. Next on the list are variables like level of activity, gender, and winter clothing. In addition, studies on energy saving have shown that living with two people instead of five might save electric heating use by 18% at a setpoint of 19° without affecting thermal comfort. Additional occupant behaviour factors and scenarios should be investigated in futuristic studies
