Get PDFThe phenomena of the tautomerism forms of the substituted triazoles compounds which are named [1-A] (5-phenyl-1H-1,2,4-triazol-3-amine), [1-B] (3-phenyl-1H-1,2,4-triazol-5-amine), [2-A] (5-(pyridin-2-yl)-1H-1,2,4-triazol-3-amine), [2-B] (3-(pyridin-2-yl)-1H-1,2,4-triazol-5-amine), [3-A] (5-(pyridin-3-yl)-1H-1,2,4-triazol-3-amine), [3-B] (3-(pyridin-3-yl)-1H-1,2,4-triazol-5-amine), [4-A] (5-(pyridin-4-yl)-1H-1,2,4-triazol-3-amine) and [4-B] (3-(pyridin-4-yl)-1H-1,2,4-triazol-5-amine) have been evaluated by Hartree-Fock (HF) method at the basis set (6-31G) in the both gas phase and at different type of solvents. This study of solvents effect was containing polar and non-polar solvent like water, acetone, acetonitrile, benzene and CCl4. The physico-chemical data's were evaluated for eigenvalues at different kinds of energy levels (HOMO, HOMO-1, HOMO-2, HOMO-3, LUMO, LUMO+1, LUMO+2 and LUMO+3). The difference of the energy gap (LUMO-HOMO) values for structures showed that the forms (1A, 2A, 3A and 4A) are more stable compare with (1B, 2B, 3B and 4B). From the results, we can showed that there is a difference between the two forms depends on the parameters. So, the imino form is not stable compare with the other structure
Test of nano-fertilizer and different irrigation intervals on yield and growth characteristics of maize Zea mays L.
No full textThe experiment was conducted in the autumn season (2019 AD) using the (RCBD) design and with three replications, in which the first factor tested the NPK nano fertilizer consisting of four levels (N4, N3, N2, N1) (0,75,150,225) PPM sequentially added twice the first with The seeds when planting. The second sprayed after a month of planting. The second factor uses different irrigation intervals consisting of three (F3, F2, F1) (8,6,4) days. The results of the experiment showed that the nano-fertilizer was significantly superior to Treatment N3 in all studied growth traits and yield, to give it the highest rate of traits: plant height, number of leaves, chlorophyll content, number of rows/horn, the weight of 500 grains, total dry matter yield, total grain yield per unit area, which amounted to (212.48 cm) and (14.04), (51.11), (13.51 row/cob), (136.83 g), (22.92 tons/ha) and (10.32 tons/ha) according to the order. As for the irrigation intervals, the irrigation interval was distinguished (every four days) and was significantly superior to the other irrigation intervals, except for the irrigation interval F2, which was distinguished in the height of the plant to give it the highest rate (203.95 cm). (234.14, 234.23) (15.13, 15.00), (55.31, 55.99), (14.13, 14.26 row/cob), (143.62, 143.62 g), (25.76, 25.63 tons/ha), (11.85, 11 .79 kg/ha) in order and without significant difference between them for the above traits
Validity Of Some International Rainfall Erosivity Models For Mosul Climatic Condition at Northern Iraq
Get PDFThe main purpose of this study was to estimate the rainfall erosivity index ( R ) of USLE for eight models to get on the most appropriate erosivity index that can be used for climatic condition of Mosul city / northern Iraq . The validity of the models has been evaluated using the monthly rainfall depth for the period of (1983 – 2012 ) .
Results showed that there is a wide variation in R value among the models. It ranged from ( 59.5 ) to ( 624.8 ) MJ.mm .ha-1.hr-1 .The reason for that may be to the variation in the basic formula of each model in estimating the errosivity index . . Statistical analysis using MAD, MSD and SE indicate that the Arnoldus model produced better predictions of erosivity at a given output time scale and generated better results than the other models. So it can be justified to use this model in future studies if required for describing the rainfall erosivity under regional climate of Mosul watershed
Communication and Network Technologies of IoT in Smart Building: A Survey
Get PDFMany industries are incorporating the Internet of Things (IoT) into their daily operations. Examples include smart homes, smart grids, smart cities, logistics, e-health, and physical security. An IoT-enabled smart building provides support for IoT applications that offer both quality and cost-effectiveness. Smart buildings are important places to deal with and manage all kinds of operating conditions, such as lighting, ventilation, humidity, temperature, safety, and others. Furthermore, it's critical to establish living spaces with better well-being standards and an enhanced quality of life. Additional problems that smart buildings create include the diversity of communication technologies and the inflexible architecture of the building. These issues include complications related to application and IoT device heterogeneity, efficient energy, security, and appropriate automation systems. This paper presents a survey of many researches on IoT in smart buildings, which we categorize into five important smart building applications: energy, localization, comfort, automation, and security. The survey is based on the most used communication technologies in smart buildings; the connectivity standards (PLC, PoE, RFID, Bluetooth, BLE, WIFI, UWB), transmission protocols (IPv6, 6LoWPAN, ZigBee, Z-wave, CoAP and MQTT), network topologies (Bus, Star, Mesh, Tree) and network area (PAN, LAN, WAN)
A review of the reinforcement performance of the photovoltaic/thermal hybrid system
Get PDFPopulation growth and economic development in most countries of this world have increased global energy needs. The international energy agencies indicated that the increase in energy consumption in developing countries is faster than in developed countries, and it requires almost twice their current capacity to meet energy demand by 2020. It is also estimated that the total energy consumption in the world will increase by 44% from 2006 to year. 2030. Therefore, alternative energy sources must be specified to meet our energy requirements and to conserve traditional fossil fuels. Solar energy is a renewable energy source. This clean energy has the potential to meet a large amount of the world's energy demand. In the field of renewable energy and energy efficiency, it has brought stability to the negative impact of carbon emissions due to the increase in energy consumption in the world, as well as the reduction of major fossil fuel sources. Photovoltaic thermal technology (PVT) has been developed since the 1970s. PVT system generates electrical and thermal energy simultaneously. The aim of this hybrid system was to use a cooling PV panel to enhance electrical efficiency, while, at the same time, utilizing thermal energy for the heating process. Most studies on PVT systems focused on the air or water-based medium for the heat transfer. In recent years, nanofluids and phase-change materials have been used with working fluid to enhance PVT thermal performance, in addition to adding some design parameters

One hundred twenty unsexed one day old (local chicks) were divided into two divisions, the first division reared on ordinary condition and called not acclimated and other division also reared on ordinary condition yet exposed to (39 ±2)°C temperature for six hours daily at age (6, 9, 12 and 15) days to acclimate them to high temperature and called acclimated. At (22) days old birds were divided into four treatments in each treatment thirty chicks with three replicate (ten birds in each). The treatments were as follows T1 Control (An acclimated), T2 Acclimated, T3 An acclimated and adding 150 mg Vit. C / Litter drinking water,T4 Acclimated and adding 150 mg Vit. C / Litter drinking water. Birds reared under cyclic temperature (25 -36 -25)°C in semi-opened houses until 56 days old. Statistical analysis of data showed a significant increase in Hetero., Lympho., Mono., Baso., Esino., pH, Hb, RBC, WBC, PCV, weight gain, body weight at slaughter, carcass weight, Relative weight of Gizzard, Spleen and Liver weight for birds of T4. Improving in Heat Tolerance in T3 and T4. No significant differences between treatments in Initial body weight, Relative Heart weight and Body Temperature

Evaluation of serum level of trace elements (iron, zinc ) in patients with celiac disease (Review study)
Get PDFCeliac disease (CD) is an immunologically-mediated disorder characterized by duodenal mucosa villi atrophy. Iron and zinc absorption is usually reduced in celiac patients making every kind of oral treatment unhelpful because of malabsorption. The present review study aimed to evaluate the level of some trace elements that have important functions in the human body in celiac patients who consume gluten and abstain from consuming it, and to compare them with healthy ones, and to see the benefit of the gluten-free diet. Serum iron (Fe+2) and zinc (Zn+2) levels were lower in patients with celiac diseas
