Authors: Hammadi Ammar A. , Izzat Amer F. , Farhan Jamal A.
Published: July 2023

Experimental work was carried out to investigate the effect of fire flame (high temperature) on specimens of one way slabs using Self Compacted Concrete (SCC). By using furnace manufactured for this purpose, twenty one reinforced concrete slab specimens were exposed to direct fire flame. All of specimens have the same dimensions. The slab specimens were cooled in two types, gradually by left them in the air and suddenly by using water. After that the specimens were tested under two point loads, to study, the effect of different: temperature levels (300ºC, 500ºC and 700ºC), and cooling rate (gradually and sudden cooling conditions) on the concrete compressive strength, modulus of rupture, flexural strength and the behavior of reinforced concrete slab specimens and comparing the results with specimens without burning (reference specimens). The results showed that, the concrete compressive strength, concrete modulus of rupture and the flexural strength decreases while the maximum (central) deflection increases with increasing the fire flame temperature. For suddenly cooled specimens the residual flexural strength is less than that of gradually cooled specimens while the deflection is greater. For slabs with 20 MPa concrete strength and gradually cooled, the residual bending strength percent is 81.5%, 75% and 62.3% ,while the increase in central deflection is 5%, 33%, and 105% at burning temperature 300ºC, 500ºC and 700ºC respectively. For suddenly cooled specimens of the same strength and exposed to the same temperatures above the residual flexural strength is 77.9%, 68.3% and 58.3% while the increase in central deflection is 25%, 52%, and 118% respectively. When the strength of concrete specimens increase, the residual flexural strength experiences small increase and the increase is of lower rate in the central deflection for 300 ºC and 500 ºC burn temperatures while the decrease is significant for 700 ºC burning temperature.

Authors: Mustafa Yasmen Abdul , Shihab Ahmed Hameed
Published: July 2023

The degradation and mineralization of 4-chlorophenol (4-CP) by advanced oxidation processes (AOPs) was investigated in this work, using both of UV/H2O2 and photo-Fenton UV/H2O2/Fe+3 systems.The reaction was influenced by the input concentration of H2O2, the amount of the iron catalyst, the type of iron salt, the pH and the concentration of 4-CP. A colored solution of benzoquinon can be observed through the first 5 minutes of irradiation time for UV/H2O2 system when low concentration (0.01mol/L) of H2O2 was used. The colored solution of benzoquinon could also be observed through the first 5 minutes for the UV/H2O2/Fe+3 system at high concentration (100ppm) of 4-CP. The results have shown that adding Fe+3 to the UV/H2O2 system enhanced the rate of 4-CP oxidation at a molar ratio of H2O2/Fe+3/4-CP equals to 13/0.4/1 by a factor of 7. This reduced the consumption of H2O2 by a factor of 6 and the irradiation time required for complete degradation was reduced by a factor of 6. The experimental results have shown that the optimum reagents for a complete degradation of 4-CP(50ppm) were H2O2.=0.005mol/L, Fe+3=0.16*10-3 mol/L under acidic condition (pH=3) and irradiation time of 15 min for the UV/H2O2/Fe+3 system with a molar ratio of H2O2/Fe+3/4-CP equals to 13/0.4/1.

A new concrete rheometer is introduced including its innovation, actual design, working rules,calibration, and reliability. A modified design of Tattersall two-point device is created. Some ofcomponents are purchased from local and foreign markets, while other components and themanufacturing process are locally fabricated. The matching viscosity method of determining the mixerviscometer constants is demonstrated and followed to relate torque and rotational speed to yield stressand viscosity (Bingham parameters). The calibration procedures and its calculation are explained.Water is used as a Newtonian fluid, while; cement paste (cement + water) with w/c ratio equal to(0.442) is used as a non-Newtonian fluid. The cement paste is tested in “Petroleum Research andDevelopment Center” by “OFITE Model 800 Viscometer”. In order to verify the reliability of the newrheometer, an Artificial Neural Network (ANN) model with a well selected bank of data is constructed;and (16) Mixes of Self Compacting Concrete (SCC) are constructed, mixed and tested by the newRheometer. The results from model (predicted) and those from the experimental work (measured) werefound to have very good degrees of correlation and matching, which indicates that the new rheometercan be reliable.

Authors: Hadi Nada Mustafa , Rashid Sarmad Abdul-Razzaq , Abdalreda Suheila
Published: July 2023

Desulfurization of a simulated diesel fuel by different adsorbents was studied in a fixed-bed adsorption process operated at ambient temperature and pressure.  Three different adsorption beds were used, commercial activated carbon, Cu-Y zeolite, and layered bed of 15wt% activated carbon followed by Cu-Y zeolite.Initially Y-zeolite was prepared from Iraqi rice husk and then impregnated with copper. In general, the adsorbents tested for total sulfur adsorption capacity at break through followed the order Ac/Cu-Y zeolite>Cu-Y zeolite>Ac. The best adsorbent, Ac/Cu-Y zeolite is capable of producing more than 30 cm3 of simulated diesel fuel per gram of adsorbent with a weighted average content of 5 ppm-S, while Cu-Y zeolite producing of about 20 cm3 of diesel fuel per gram of adsorbent with a weighted average content of 2ppm-S. Activated carbon breaks through almost immediately.

Authors: Ismail Zainab Ziad , Abdulrazzak Ibtihaj Abdlwahab
Published: July 2023

A new application of a combined solvent extraction and two-phase biodegradation processes using two-liquid phase partitioning bioreactor (TLPPB) technique was proposed and developed to enhance the cleanup of high concentration of crude oil from aqueous phase using acclimated mixed culture in an anaerobic environment. Silicone oil was used as the organic extractive phase for being a water-immiscible, biocompatible and non-biodegradable. Acclimation, cell growth of mixed cultures, and biodegradation of crude oil in aqueous samples were experimentally studied at 30±2ºC. Anaerobic biodegradation of crude oil was examined at four different initial concentrations of crude oil including 500, 1000, 2000, and 5000 mg/L. Complete removal of crude oil was achieved biphasic bioreactor after 3 weeks compared to 73-82% in the monophasic bioreactor for the same time period.

Authors: Alsaadi Hassan Abdulkadhim Alwan
Published: July 2023

Water injection equipments such as pipelines, which are used in the second recovery of oil in the Al-Ahdeb wells, suffer from the corrosion in water during maintaining vacuum deoxygenated tower that used to decrease concentration of the dissolved oxygen gas in the water from 6.2-9.1 ppm to o.5 ppm. This study involved calculation the corrosion rates of the internal surfaces of the pipelines either during operation of the vacuum unit or when the tower out of operation. Finally, find the solution by one of the following suggestions. In the first suggestion removal of the dissolved O2 from water is achieved by increasing the dosage of the oxygen scavenger (sodium sulphite). The second suggestion involves removing the dissolved O2 from water by bubbling the oxygenated water with nitrogen gas. The study showed that the corrosion rates of various inside diameter pipelines are between 0.13 mm/yr and 1.5 mm/yr during operation of the vacuum tower and between 3.2 mm/yr and 18.5 mm/yr when the tower out of the operation. While the results showed that the corrosion rate of the pipelines when the tower out of operation reached to the acceptable value of 0.1 mm/y when the dissolved oxygen in the injected water removed by increasing the dosage of the sodium sulphite (Na2SO3) to 48-72 ppm. The results also explained that corrosion rates of the pipelines reached to 0.5 mm/y when the dissolved oxygen removed by bubbling the water with nitrogen gas.

Authors: Rashed Sosan M. , Mahjoob Ahmed M. R.
Published: July 2023

Scheduling considered being one of the most fundamental and essential bases of the project management. Several methods are used for project scheduling such as CPM, PERT and GERT. Since too many uncertainties are involved in methods for estimating the duration and cost of activities, these methods lack the capability of modeling practical projects. Although schedules can be developed for construction projects at early stage, there is always a possibility for unexpected material or technical shortages during construction stage. The objective of this research is to build a fuzzy mathematical model including time cost tradeoff and resource constraints analysis to be applied concurrently. The proposed model has been formulated using fuzzy theory combining CPM computations, time-cost trade off analysis and resource constraint. MATLAB software has been adopted to perform ranking process, for each case, that facilitates obtaining the optimum solution. This research infers that it is possible to perform time-cost trade off analysis with resource restriction simultaneously, which ensures achieving scheduling optimum solution reducing the effort and the time when performing these techniques in succession using traditional methods.
Comparative Study for Risk Criteria of Al-Qudus Plant between the Present and Planning of MOE
Authors: Lafta Yesar Noori
Published: July 2023

The main function of a power system is to supply the customer load demands as economically as possible. Risk criterion is the probability of not meeting the load. This paper presents a methodology to assess probabilistic risk criteria of Al-Qudus plant before and after expansion; as this plant consists of ten generating units presently and the Ministry Of Electricity (MOE) is intending to compact four units to it in order to improve the performance of Iraqi power system especially at Baghdad region. The assessment is calculated by a program using Matlab programming language; version 7.6. Results show that the planned risk is (0.003095) that is (35 times) less than that in the present plant risk; (0.1091); which represents respectable improvement. This probabilistic method can also be used to find the planned risk level of every plant to be compact in the Iraqi electrical network on the future; or any other power systems; and compare it with the present criterion which is very useful to determine the necessary generation capacity expansion.

Authors: Faisal Ayad Abdulhamza , Abbas Talib Rasheed , Jassam Salim Hrez
Published: July 2023

The possibility of using zero-valent iron as permeable reactive barrier in removing lead from a contaminated groundwater was investigated. In the batch tests, the effects of many parameters such as contact time between adsorbate and adsorbent (0-240 min), initial pH of the solution (4-8), sorbent dosage (1-12 g/100 mL), initial metal concentration (50-250 mg/L), and agitation speed (0-250 rpm) were studied. The results proved that the best values of these parameters achieve the maximum removal efficiency of Pb+2 (=97%) were 2 hr, 5, 5 g/100 mL, 50 mg/L and 200 rpm respectively. The sorption data of Pb+2 ions on the zero-valent iron have been performed well by Langmuir isotherm model in compared with Freundlich model under the studied conditions. Finite difference method and computer solutions (COMSOL) multiphysics 3.5a software based on finite element method were used to simulate the one-dimensional equilibrium transport of lead through sand aquifer with and without presence of barrier. The predicted and experimental results proved that the reactive barrier plays a potential role in the restriction of the contaminant plume migration and a reasonable agreement between these results was recognized.

A good command of computational and statistical tools has proven advantageous when modelling and forecasting time series. According to recent literature, neural networks with long memory (e.g., Short-Term Long Memory) are a promising option in deep learning methods. However, only some works also consider the computational cost of these architectures compared to simpler architectures (e.g., Multilayer Perceptron). This work aims to provide insight into the memory performance of some Deep Neural Network architectures and their computational complexity. Another goal is to evaluate whether choosing more complex architectures with higher computational costs is justified. Error metrics are then used to assess the forecasting models' performance and computational cost. Two-time series related to e-commerce retail sales in the US were selected: (i) sales volume; (ii) e-commerce sales as a percentage of total sales. Although there are changes in data dynamics in both series, other existing characteristics lead to different conclusions. "Long memory" allows for significantly better forecasts in one-time series. In the other time series, this is not the case.

Published: July 2023

This paper reports the use of dielectric barrier discharge (15.65 kV, 50 Hz) produced in an air and argon environment at atmospheric pressure to modify the surface of Nylon 6. Power dissipation in air and argon DBD was determined to be 14.60 W and 12.00 W, respectively. Similarly, the average density and temperature of an electron in air DBD were found to be 1.74 ×1011 cm-3 and 1.31 eV, respectively, while the values were 2.50 ×1011 cm-3 and 0.68 eV in argon DBD. The water contact angle (WCA) was measured to confirm the enhancement in wettability. On treating the sample with air DBD for 15 minutes, the contact angle reduced from 134.07° ± 3.20° to 89.11° ± 3.06° while it was reduced to 82.74° ± 4.20° within 1 minute using argon. The study found that treating a hydrophobic sample of Nylon 6 with DBD for a certain period of time transformed it into a hydrophilic one, and extending the treatment time further enhanced its wettability. The use of argon DBD was found to be more effective than air DBD in altering the surface properties of the sample, as the sample became hydrophilic after only one minute of treatment with argon DBD and completely wettable after three minutes. The findings suggest that air and argon DBD have potential applications in modifying the surface properties of Nylon 6, which could have practical implications in the production of textiles, membranes, and other materials.
Caputo-Fabrizio approach to numerical fractional derivatives
Authors: Pariyar Shankar , Kafle Jeevan
Published: July 2023

Fractional calculus is an essential tool in every area of science today. This work gives the quadratic interpolation-based L1-2 formula for the Caputo-Fabrizio derivative, a numerical technique for approximating the fractional derivative. To get quadratic and cubic convergence rates, respectively, we study the use of Lagrange interpolation in the L1 and L1-2 formulations. Our numerical analysis shows the accuracy of the theory’s predicted convergence rates. The L1-2 formula aims to enhance the accuracy and usability of a flexible tool for many applications in science and mathematics. We demonstrate the validity of the theory’s predicted convergence rates using numerical analysis. Several numerical examples are also given to show how the suggested approaches may be utilized to determine the Caputo-Fabrizio derivative of well-known functions. Lagrange interpolation is used in the L1 and L1-2 procedures to obtain quadratic and cubic convergence rates, respectively. The numerical study demonstrates that the L1-2 formula offers greater accuracy when compared to current approaches. In addition, it is a better apparatus for several applications in science and mathematics. Due to its higher convergence rate, the L1-2 formula outperforms other available numerical methods for scientific computations. The L1-2 formula, a novel numerical method for the Caputo-Fabrizio derivative that makes use of quadratic interpolation, is introduced in this study as a conclusion.

Authors: Subba Bimala , Subedi Namrata , Parajuli Sanju
Published: July 2023

This study was designed to explore phytochemicals and biological activities of methanolic extract of six traditional medicinal plants (Clerodendrum trichotomum, Mallotus philipinensis, Dioscorea-bublifera, Rubia cordifolia, Viscum articulatum) of Nepalese origin. Plant extracts were prepared in methanol through cold percolation. Analysis of phytochemical constituent, antioxidant capacities and brine shrimp lethality assay of the test plant samples were carried out using standard methods. The 1,1-diphenyl-2-picryl hydrazyl (DPPH) method was used to study antioxidant activity of different plant extracts. Furthermore, starch-iodine method was used to study the inhibition effect of extract on α-amylase. Phytochemical analysis showed the presence of phytochemicals like alkaloids, flavonoids, phenolic content, glycosides, reducing sugars, etc. in six medicinal plants. Brine shrimp lethality assay suggested the presence of pharmacologically active compounds. Total phenolic content and total flavonoid content of C. trichotomum’s leaves extract were found to be higher with 212.742 mg GAE/g and 112 mg Q/g respectively with strong antioxidant activity. Similarly, the α-amylase inhibition of R. cardifolia’s root extract and C. trichotomum‘s leaves extract was found to be 252.44±0.55 µg/mL and 293.33± 0.81 µg/mL comparative with IC50 value 119.063±0.73 µg/mL of standard acarbose that showed remarkable antidiabetic property among six samples. The results, obtained here suggested that six medicinal plants i.e. C. trichotomum, M. philipinensis, D. deltoidea, D. bublifera, R. cordifolia, and V. articulatum, Nepal origin showed biological activity by targeting multiple drug targets which justifies their traditional uses. This is the first finding that C. trichotomum‘s leaves can be a promising source for the development of natural antioxidant and antidiabetic agents.
Of Monetary Policy Analysis and Output Shocks
Authors: Maskay Nephil Matangi
Published: July 2023

Nepal and India are contiguous countries having a pegged exchange rate arrangement existing for forty years with virtually no restrictions on labor or capital mobility. However, empirical analysis suggest the levels of the Nepalese and Indian monetary base do not share a long term relationship. Conditioning the monetary policy variables by output shocks (i.e. by their respective economic structures) now show them to be cointegrated. This implies that a long-term monetary analysis using unconditional variables may be misleading.

Authors: Adhikari Shiva Raj , Maskay Nephil Matangi , Sharma Bishnu Prasad
Published: July 2023

There is a strong positive relationship between health of the people and sustained economic development of a nation. Given its importance for sustained economic development, the Nepalese health policies are examined through the perspective of the various development plans which suggests that enunciation of clear health objectives have only recently occurred starting from the fifth development plan. However, this contrasts with the empirical observations which suggest that Nepalese public health expenditure over the last decade has had limited direct impact on the health sector outcomes; this observation for Nepal is based on analysis from an input-output model, examination of extension of health facility and through results of an indicative regression. The paper ends with some policy recommendations to Nepalese health policies, based on the empirical analysis, to facilitate the nation’s health to play its important role in economic development.
An Assessment of the Impact of External Debt on Economic Growth of Nepal
Authors: Bhatta Gunakar
Published: July 2023

Countries at early stages of development have small stocks of capital and require foreign borrowing for their investment needs and meet their external resource gap. Nepal's dependence on foreign assistance, nearly for the last five decades, can be viewed from the same perspective. The present article is a preliminary work in the direction of analyzing the relationship of external debt and economic growth of Nepal. The examination of debt burden indicators suggests the increasing burden of external debt, with a significant increase in the size and magnitude of such debt during 1990s. The empirical observation shows the external debt flow having positive effect on economic growth. This indicates that external debt should not be viewed only as a burden but also as a major source of financing for a developing economy like Nepal. However, the analysis of external debt stock and debt servicing shows that the equally important that external borrowing be made to supplement but not replace domestic savings in the long run.
Money and Its Role of Income Stabilization: An Econometric Diagnosis
Authors: Paudel Bamadev
Published: July 2023

There is a continuous debate over the transmission mechanism of monetary impulses on economic activities in developed as well as developing countries, and the debate revolves around two broad categories of transmission channels- the Keynesian and the Quantity Theory. Keynesian transmission mechanism examines the effect of money on economic activities by building the structural model. The basic Keynesian view is that the impact of the change in money stock on real income results indirectly through change in the rate of interest rate and thereby investment expenditure. The Quantity Theory of Money, on the other hand, is associated with reduced-form economic model, in which the effect of money on economic activities is examined by looking whether movements in income are tightly linked to movements in money supply. Monetarists analyze the effect of change in money supply on the change in income level as if the economy is a black box in which its working can not be detected. This paper tries to find out the relationship between money and income by using reduced-form models. The empirical results show that there is a strong positive association between money and its role of income stabilization. It is true both for nominal as well as real terms. The lagged response of money supply on income is two years in nominal terms and three years in real terms. There is also the structural shift in the role of money for income stabilization, indicating that money has become more effective during the liberalization period to determine the income level of the economy.

French as a second language (FSL) teachers in Canada face unique circumstances and challenges in the profession, from their initial teacher preparation into the beginning years of teaching and beyond. These challenges play a role in the long-standing FSL teacher shortage across Canada. To better understand the complexity and nuance of issues facing teachers of FSL in minority settings, we conducted a study in 2021 across different regions in Canada that included 29 focus groups with a total of 89 participants from three key stakeholder groups: teacher educators working in faculties of education; school district and board representatives; and FSL teachers, with a focus on recently graduated novice teachers. In our analysis, we found that participants’ unique and contextualized experiences are framed around two key points of convergence in our data: access and conceptualizations. We present and discuss these findings, considering practical and ideological elements stemming from these points of convergence. We then conclude the paper with a synthesis of the complexities and interconnectedness inherent in the factors related to FSL teacher preparation and support, including a reflection on what this might ultimately tell us about the FSL teacher shortage.
Building Sustainable Funding for Teacher Residency Programs
Authors: Finster Matthew , Fermanich Mark
Published: July 2023

Schools across the U.S. are facing substantial challenges filling positions ( Bleiberg & Kraft, 2022 ) and are considering solutions to address potential teacher shortages. As of 2022, almost half of the States in the U.S. create or support teacher residency programs (TRPs) through statute or regulation ( Education Commission of the States, 2022 ). TRPs are a structured, alternative mode of entry into the education profession that combines coursework in education with extensive on-the-job training, modeled after medical residencies ( Guha et al. 2016 ; Silva et al. 2014 ). To fulfill its promise, TRPs need to be organized and funded to offer living stipends to attract high-quality candidates with diverse backgrounds and experiences while providing them with intensive preparation. In this commentary article, we discuss “4 Rs” of sustainable funding: Reallocation, Reduction, Reinvestment, and Realignment. The literature suggests that most of the needed resources are already in the system, but they need to be realigned and reapplied. This transition can occur through cooperation and collaboration among state policymakers, EPPs, and local school districts.
مصر بعيون رحالة فارسي (438 - 444هـ/ 1045-1052م) النص الرحلي وراهنية قراءة الحدث
Authors: البهيني عبد المجيد
Published: July 2023

تطرح هذه الورقة البحثية، موضوع توظيف المتن الرحلي في البحث التاريخي، وما يكتنف ذلك من مخاطر منهجية ترتبط أساسا بتفاعل الرحالة الفوري مع ما يرى من أحداث وما يصف من ظواهر وأوضاع. وقد يؤدي هذا التفاعل حينا، بالنظر إلى قرب عهد المؤلف بالحدث، وعدم أخذ وقت كافي لقراءته قراءة صحيحة، إلى الخروج باستنتاجات وتأويلات مجانبة للصواب ومخالفة للحقيقة؛ وطورا إلى تشكيل صورة أو بناء موقف مبالغ فيه خصوصا إذا كان للمؤلف تعاطفا وميلا لجهة معينة. وسعيا لبيان ذلك، اخترنا الاشتغال على نص رحلة ناصر خسرو إلى مصر، حيث يتضمن وصفا لأوضاعها السياسية ونظمها الإدارية والعسكرية والجبائية في عهد المستنصر الفاطمي. لم يقتصر ناصر خسرو على الوصف والملاحظة، بل كان يدلي بوجهة نظره الإيجابية إزاءها، دون ترك مسافة زمنية كافية تسمح له بالقيام، أحيانا، بقراءة واقعية موضوعية لما شاهد من أحداث، وسمع من أخبار ورأى من ظواهر. وقد يُبَرر ذلك بميوله الشيعي واعتناقه للمذهب الإسماعيلي؛ لذلك يغلب على الحيز المخصص لمصر في الكتاب المدح والإطراء والتمجيد.

Authors: Derkach Iryna , Klymenko Sofiya
Published: July 2023

The relevance of the study is conditioned upon the need to summarise current data on the pharmacological properties of Basidiomycota and to provide scientific justification for their use in veterinary medicine. The purpose of the research was to analyse the results of recent experimental studies on the pharmacological and toxicological properties of basidiomycetes and the possibilities of their use in veterinary medicine. The research uses theoretical methods of analysis and comparison of literature data with the development of substantiated conclusions and recommendations for the future. Basidiomycetes belong to the higher fungi, their vegetative body is represented by a branched cellular mycelium. They are a healthy food and rich in biologically active substances. Analysis of the literature demonstrates a high degree of scientific interest in the research of their pharmacological properties. Consequently, scientific research is designed to establish new data on the pharmacodynamics and pharmacokinetics of biologically active substances of basidiomycetes. For example, the mushroom Inonotus obliquus (I. obliquus) has been commonly used to treat patients with various gastrointestinal diseases. In recent years, there has been a growing body of scientific evidence indicating the effectiveness of its extracts in treating infections and infestations, cancer, and diabetes. It was established that the biologically active substances of I. obiquus stimulate the immune system, show hypoglycaemic potential, are sensitive to insulin, and have an antioxidant effect. In the current scientific discourse, researchers are trying to identify the molecular mechanism of action of I. obliquus extracts. The presented review of the literature demonstrates that basidiomycetes exhibit pharmacological properties in cancer and neurodegenerative diseases, diseases of the digestive, respiratory and cardiovascular systems, metabolic disorders, antimicrobial, antiviral, immunomodulatory effects, etc. Currently, using basidiomycetes in the world, considering their scientifically proven and experimentally proven pharmacological properties, is extremely promising. The material of the research is of practical value for expanding the possibilities of using fungotherapy in veterinary medicine

The Indonesian government has implemented various regulations to suppress the Covid-19 case. The majority of these policies limit mass activities, such as education. Thus, online education policies were initiated via various platforms with the need for access via the internet. However, military education institutions such as Secapa AD require face-to-face interactions and field-based learning to obtain appropriate learning outcomes. Therefore, a special policy was created for Diktukpassus T.A. 2021 which briefly has a quarantine period at the beginning of education. This period was filled with online learning. Various challenges, both external and internal, must arise. This research will reveal the opinions of students and teachers regarding the implementation of online learning using the interview and FGD methods. In the end, the respondents' sentiments led to the choice of studying offline rather than online. However, respondents also felt that online learning had a positive side and room for growth.
