Determination the Wheat Weight and Volume: Mathematical Approach
...Show More Authors
Abstract<p>Grain size and shape are important yield indicators. A hint for reexamining the visual markers of grain weight can be found in the wheat grain width. A digital vernier caliper is used to measure length, width, and thickness. The data consisted of 1296 wheat grains, with measurements for each grain. In this data set, the average weight (We) of the twenty-four grains was measured and recorded. To determine measure of the length (L), width (W), thickness (T), weight (We), and volume(V). These features were manipulated to develop two mathematical models that were passed on to the multiple regression models. The results of the weight model demonstrated that the length and width of the grains were significantly different <italic>p < 0.0001</italic>. The coefficient of grain width was higher than that of grain length, indicating that grain width was more important than grain length. Furthermore, the overall model for volume was significantly different, (<italic>F</italic> <sub>(2,1295);</sub> =446832, <italic>p < 0.0001</italic>), regression(R<sup>2</sup>)-Square= 0.9986, Adj R-Sq=0.9986; and the RMSE of the experimental was RMSE=0.0002. The results of the weight model showed that the length, width, and thickness of the grains were significantly different <italic>p < 0.0001</italic>. The coefficient of grain the thickness was greater than the coefficient of grain length, indicating that the grain thickness was more significant than the grain length, and the coefficient of the grain width was more significant than the grain length. Moreover, the overall model for volume was significantly different (<italic>F</italic> <sub>(3,1295);</sub> =71809.6, <italic>p < 0.0001</italic>), regression (R<sup>2</sup>) and Adj-R-Sq = 0.9940 were equal, and RMES=0.3399. The introduced model may allow farmers to predict the weight and volume of wheat production during the wheat grain season, depending on the grain length, width, and thickness.</p>

The Catholyte Effects on The Microbial Desalination Cell Performance of Desalination and Power Generation
...Show More Authors

A microbial desalination cell (MDC) is a new approach to bioelectrochemical systems. It provides a more sustainable way to electrical power production, saltwater desalination, and wastewater treatment at the same time. This study examined three operation modes of the MDC: chemical cathode, air cathode, and biocathode MDC, to give clear sight of this system's performance. The experimental work results for these three modes were recorded as power densities generation, saltwater desalination rates, and COD removal percentages. For the chemical cathode MDC, the power density was 96.8 mW/m2, the desalination rate was 84.08 ppm/hr, and the COD removal percentage was 95.94%. The air cathode MDC results were different

The Separation Worry and its Correlation with Working Memory of the Primary School Pupils
...Show More Authors

The concept of the separation worry is considered one of the common disorders in children. The causes and effects of this worry influence the child mental and cognitive ability and the child ability to communicate with others, has friendship and the ability of adaptive with the environment, peers and teachers and it also influences the child's academic and social performance.
The importance of this study is represented in handling the working memory, one of important subject in cognitive psychology. Many universal studies show that the working memory is very important in several daily functions such as continuous attention, followinstructions, implement instructions of many steps, the moment of information remembering and keep focusin

PDF The effect of nanoelectrodes number and length on enhancing the THz photomixer performance
...Show More Authors

Abstract: Despite the distinct features of the continuous wave (CW) Terahertz (THz) emitter using photomixing technique, it suffers from the relatively low radiation output power. Therefore, one of effective ways to improve the photomixer emitter performance was using nanodimensions electrodes inside the optical active region of the device. Due to the nanodimension sizes and good electrical conductivity of silver nanowires (Ag-NWs), they have been exploited as THz emitter electrodes. The excited surface plasmon polariton waves (SPPs) on the surface of nanowire enhances the incident excitation signal. Therefore, the photomixer based Ag-NW compared to conventional one significantly exhibits higher THz output signal. In thi

THE WATER ECOSYSTEM OF THE MARSHES OF MAYSAN GOVERNORATE USING REMOTE SENSING AND GIS
...Show More Authors

The study addressed the water ecosystems of the marshes of Maysan Governorate as one of the important areas in Iraq in terms of the environmental, economic and tourism aspects. This area was exposed to great environmental changes due to natural and human factors which greatly affected the water ecosystem and made the area susceptible to many problems that affected the biological life of living organisms. The marshes of Maysan Governorate was affected by vital factors and non-vital factors. The marshes of Maysan Governorate was characterized by the UN Organization as one of the most important centers of biodiversity in the world because of the abundance of different and rare living organisms such as birds, fish, and reptiles as well as the e

Metaphors and comparisons as a means of rethinking the phenomena of the surrounding world
...Show More Authors

The article characterizes metaphors and comparisons as a means of rethinking the phenomena of the surrounding world; two directions are named within which metaphors and comparisons are studied: 1) the linguo-classification direction combines several classifications of metaphors and comparisons, which are basically focused on comparing two denotations through the meanings of word forms that are part of the trope; 2) the theoretical and conceptual direction is associated with the concept of conceptual displacement and is the basis of the theoretical and methodological study of metaphor and comparison, i.e. the modern theory of metaphor is being formed; The main attention is focused on the comparative concept of Aristotle, which postul

" Forecasting Future Cash Flows Using the Metrics of Cash Flow and the Accounting Return "
...Show More Authors

Providing useful information in estimating the amount and timing and the degree of uncertainty concerning the future cash flows is one of the three main objectives of the financial reporting system, which is done through the main financial statements. The interest on standard-setting bodies in the forecasting of future cash flows, especially Financial Accounting Standards Board (FASB) explain under Accounting Standard (1) of the year 1978 "Objectives of Financial Reporting by Business Enterprises", paragraph (37) thereof that accounting profits better than cash flows when forecasting future cash flows, In contrast, IAS (7) as amended in 1992 aims to compel economic units to prepare statement of c
