Lighting systems are among the most energy-intensive systems in the home because they consume a lot of electricity. Nighttime blackouts are currently being caused by an urgent need for lighting ...systems, especially emergency lighting. PLN and the battery provide electrical energy for emergency lighting. DC-DC converters that use the bidirectional method regulate electrical energy sources. PLN bidirectional converters have two functions, namely buck mode and boost mode, which work whenever the primary source of PLN is out, the battery will automatically supply the lighting system. In this research, the bidirectional converter can switch from buck mode to boost mode depending on the voltage of the power supply When the power supply voltage is low, the converter will switch to buck mode to reduce the voltage, and when the power supply voltage is high, the converter will switch to boost mode to increase the voltage. This allows the battery to be used as a backup power source when the main source fails. A lamp load of 10 W is used in the boost mode of the discharging process. Analytical proportional integral control methods are used to control the charging and discharging processes.

The study included three levels of organic fertilizer (4, 8, 12 t/ha) and three dates for thinning plants (20, 30, 40 days from planting). Experiment was carried out according to randomized complete block design (RCBD) with three replications. The results showed that the fertilizer level exceeded 30 t/ha significantly in plant height, number of branches / plant, leaf area, number of heads/ plant, 1000-seed weight, seed yield, Percentage of oil and oil yield in both study sites, while the fertilizer level exceeded 15 t/ha in number of seeds/head. Date of thinning of plants after 20 days after planting significantly exceeded in the characteristics of number of branches / plant, leaf area, number of heads/ plant, number of seeds/ head, 1000-seed weight, seed yield, Percentage of oil and oil yield at both study sites, while the date of thinning after 40 days after planting exceeded in plant height. Interference between the fertilizer level exceeded 30 t/ha with the date of thinning of plants 20 days after planting in the characteristics of leaf area and seed yield.

Any educational institution aimed at developing towards e-learning and creating a more interactive environment and use in all fields of governmental institutions. The Ministry of Higher Education and ...Scientific Research (MOHESR) of Iraq and some of the countries in the Middle East suffer from weak use of information technology in general and weak use of e-learning in particular. Therefore, Iraqi MOHESR is in dire need of an electronic educational system that solves most of the problems experienced by most educational institutions.In this paper, we will develop a strategic plan to build an e-learning platform that provides an interactive environment between teachers and students in Iraqi universities and offers many advantages to overcome some problems in the use of traditional old education. This work is related to the use of multi-layered architecture to build the e-learning platform (Standard design of e-learning platform for IraqiMOHESR). The advantage of these layers is that each layer is created in the Asp.Net program using N-Tier architecture that has functions that are independent of the rest of the layers which are(user interface(UI), business Access Layer(BAL),Data AccessLayer(DAL), Database(DB)). A particular object will not affect the rest of the layers or the performance of these layers.
Abstract
This study introduces a novel triple-tube latent heat storage system enhanced with circular angled fins to improve solidification and heat recovery performance. The fins are arranged in ...staggered pattern with alternating upward and downward orientations on both sides of the PCM shell. A validated numerical model was developed using the enthalpy method to simulate the intricate heat transfer and phase change physics. Effects of circular fins geometry and operating conditions were systematically quantified on discharge rates and temperature uniformity. Four fin dimension cases (thickness × length): (2 × 5), (1 × 10), (0.66 × 15), and (0.57 × 17.5) mm2 were analyzed. The results demonstrate that fins with greater length and reduced thickness exhibit superior performance due to enhanced heat transfer capabilities, resulting in quicker solidification and faster heat retrieval. The longest 17.5-mm fins, achieving full solidification in 1973 s with 44%, 19%, and 1.9% quicker than cases with 5-mm, 10-mm, and 15-mm long fins, respectively. Incorporating an additional fin upward further reduces the solidification time by 4.5% while improving heat recovery by 3.6%. The 17.5-mm long fins increase heat discharge by 48% and outlet heat-transfer fluid temperatures by 39% versus straight fin baselines. Lower inlet heat-transfer fluid temperatures (10°C vs 20°C) reduce PCM solidification times by 31% (1755s vs 2554s) while increasing heat recovery rates by 57% (56.3 W vs 35.8 W). Overall, the integrated angled fins create a customizable latent heat storage system with greatly intensified heat transfer and thermal performance compared to conventional shell-and-tube arrangements.
