The utilization of radiation in the field of nuclear medicine uses several main tools, one of them is the gamma camera. In its use, the gamma camera must always be in prime condition in accordance with the regulation of the Badan Pengawas Tenaga Nuklir (BAPETEN) No. 17 of 2012. To ensure that the gamma camera is always in prime condition, it is necessary to carry out several QCs (Quality Control) within a certain period of time with reference to international standards and recommendations from manufacturers.  QC results show the measured value still within the required range (acceptance criteria), so it can be said that the gamma camera is in prime condition and ready to be used. The Nuclear Medicine Installation of RSUD A. W Sjahranie Samarinda use Cobalt-57 flood source plates  to measure extrinsic uniformity during daily QC. This study used data in the form of tables of extrinsic calibration measurements and verification measurements as well as graphs of Cobalt-57 activity against QC time with extrinsic calibration methods and verification measurements were shown in this study. The conclusion is the lower the activity, the longer the QC times. Besides, the QC times based on the extrinsic callibration and verification measurements are not much different.

Published: July 2023

As a result of the growth of economic, demographic and building activities in Iraq, that necessitates carrying out geotechnical investigations for the dune sand to study behavior of footings resting on these soils. To determine these properties and to assess the suitability of these materials for resting shallow foundation on it, an extensive laboratory testing program was carried out. Chemical tests were carried out to evaluate any possible effects of the mineralogical composition of the soil on behavior of foundation rested on dune sands.Collapse tests were also conducted to trace any collapse potential. Loading tests were carried out for optimum water content and different shapes of footing. Loading test recommends manufacturing of steel box and footing models with different shapes and dimensions. The results indicated that, Affek dune sand is predominantly fine sand with non-plastic fines.Because the content of sulphate (as SO3) is only 0.05%, and the alkalinity of dune sand, which reduces the corrosion potential, ordinary Portland cement can be used in concrete foundation construction in/on dune sands. The results of collapsing tests showed that Affek dune sand exhibit a slight to moderate potential depending on stress level. Due to Soaking by water, the reduction in bearing capacity of optimum state was about 45%. The bearing capacity of square footing was greater than those of the circular and rectangular footings.

Authors: Izzat Amer F.
Published: July 2023

Experimental research was carried out to investigate the effect of fire flame (high temperature) on specimens of short columns manufactured using SCC (Self compacted concrete). To simulate the real practical fire disasters, the specimens were exposed to high temperature flame, using furnace manufactured for this purpose. The column specimens were cooled in two ways. In the first the specimens were left in the air and suddenly cooled using water, after that the specimens were loaded to study the effect of degree of temperature, steel reinforcement ratio and cooling rate, on the load carrying capacity of the reinforced concrete column specimens. The results will be compared with behaviour of columns without burning (control specimens). The results showed that, the ultimate load capacity of columns exposed to fire decreases with increasing the fire flame temperature. At burning temperature 300 Co , 500 Co and 700 Co , the average residual ultimate load capacity for gradually cooled specimens were 91%, 81% and 71% respectively. By increasing the ratio of longitudinal reinforcement 44% , the maximum improvement in the ultimate load capacity was 24% and 17% for the gradually and sudden cooling respectively at Co 500 . For the same longitudinal reinforcement ratio and fire burning temperature, the ultimate capacity for the sudden cooling specimens was less than that of gradually cooled specimens by about 10%.

Authors: Ismail Zainab Ziad , Talib Ali Raad
Published: July 2023

Anaerobic digestion is a technology widely used for treatment of organic waste for biogas production as a source for clean energy. In this study, poultry house wastes (PHW) material was examined as a source for biogas production. The effects of inoculum addition, pretreatment of the substrate, and temperature on the biogas production were taken into full consideration. Results revealed that the effect of inoculum addition was more significant than the alkaline pretreatment of raw waste materials. The biogas recovery from inoculated waste materials exceeds its production from wastes without inoculation by approximately 70% at mesophilic conditions. Whereby, the increase of biogas recovery from pretreated wastes was by 20% higher than its production from untreated wastes at mesophilic conditions. The thermophilic conditions improved the biogas yield by approximately 73%. The kinetic of bio-digestion process was well described by modified Gompertz model and the experimental and predicted values of biogas production were fitted well with correlation coefficient values > 0.96 suggesting favorable conditions of the process.

Published: July 2023

Numerical study of separation control on symmetrical airfoil, four digits (NACA

0012) by using rotating cylinder with double steps on its upper surface based on the computation of Reynolds-average Navier- Stokes equations was carried out to find the optimum configuration of unconventional airfoil for best aerodynamics performance. A model based on collocated Finite Volume Method was developed to solve the governing equations on a body-fitted coordinate system. A revised (k-w) model was proposed as a known turbulence model. This model was adapted to simulate the control effects of rotating cylinder. Numerical solutions were performed for flow around unconventional airfoil with cylinder to main stream velocities ratio in the range of 1 to 4 and for various positions of the steps on the airfoil from the leading edge, 0.1c, 0.2c, 0.3c, 0.4c, 0.5c for the first step and 0.5c, 0.6c, 0.7c, 0.8c for the second step with constant step depth and length of 0.03c and 0.125c respectively. Reynolds number of 700,000 which was based on the cord length (c), with angle of attacks 0, 5, 8, 10, 12, 15 degrees was considered for the assessment of the unconventional airfoil performance. The numerical investigation showed that the optimum configuration for the unconventional airfoil was found to be at velocities ratio (U/U∞=4) with the steps positions at 0.5c and 0.8c for best airfoil performance.
The Effective Width in Composite Steel Concrete Beams at Ultimate Loads
Authors: Mohsen Mohannad Husain , Mohammed Salam Naseer
Published: July 2023

A composite section is made up of a concrete slab attached to a steel beam by means of shear connectors. Under positive and negative bending moment, part of the slab will act as a flange of the beam, resisting the longitudinal compression or tension force. When the spacing between girders becomes large, it is evident that the simple beam theory does not strictly apply because the longitudinal stress in the flange will vary with distance from the girder web, the flange being more highly stressed over the web than in the extremities. This phenomenon is termed "shear lag". In this paper, a nonlinear three-dimensional finite element analysis is employed to evaluate and determine the actual effective slab width of the composite steel-concrete beams by using theAnalysis System computer program (ANSYS 11.0). The of elements were used (SOLID65, LINK8, SHELL143, COMBIN39, TARGE170 andCONTA174) to model the concrete slab, the steel reinforcing bars, the steel girder, the shear connectors (including uplift and dowel action), and the interface between top flange of the steel girder and concrete slab, respectively. Comparisons with experimental tests have been performed to validate the finite element analysis results. In general, excellent agreement between the finite element solution and the experimental results has been obtained. The maximum difference in ultimate load is about (2.9%). Finally, parametric studies have been carried out to investigate the effect of some important parameters; these parameters include the degree of interaction, slab thickness, slab width, concrete compressive strength ( ), distribution of shear connectors, reinforcement of slab, type of loading, and boundary conditions. The effect of changing these parameters causes variety in the effective slab width and the maximum stress reaches 40.7% and 28.5%, respectively.

Published: July 2023

Leaching scheduling techniques are one of the suggested solutions for water scarcity problems .The aim of the study is to show the possibility of using leaching scheduling, when applying the irrigation scheduling program for a certain irrigation project, which was prepare by Water Resources Engineering –University of Baghdad with some modifications to generalized it and it make applicable to various climatic zone and different soil types.The objectives of this research is to build a system that concerns the prediction of the leaching scheduling (depth and date of leaching water), illustrating the main problems (soil salinity, save the amount of leaching requirement, and to maintain crops growth).The other objective is to compare between the calculated amount of leaching water with the amount of water that is suggested by designers. The program includes, the calculating of predicted daily soil salinity ,the depth of leaching water that should be applied to remove the salt from the soil when it reaches a harmful level, and the total annual volume of leaching water. The results showed, that the use of predicted leaching scheduling with its applicable constrains require high attention when choosing the cropping pattern for each climate zone. Also, it was found that the leaching program is a useful tool for saving irrigation water if cropping pattern has been adapted carefully. This means the leaching water depth should be added only when needed, and may not be necessary with each irrigation event.
New Approach in Detection MAC Spoofing in a WiFi LAN
Authors: Ali Hamid Mohamed , Abbas Ammna Mohamed
Published: July 2023

Medium Access Control (MAC) spoofing attacks relate to an attacker altering the manufacturer assigned MAC address to any other value. MAC spoofing attacks in Wireless Fidelity (WiFi) network are simple because of the ease of access to the tools of the MAC fraud on the Internet like MAC Makeup, and in addition to that the MAC address can be changed manually without software. MAC spoofing attacks are considered one of the most intensive attacks in the WiFi network; as result for that, many MAC spoofing detection systems were built, each of which comes with its strength and weak points. This paper logically identifies and recognizes the weak points and masquerading paths that penetrate the up-to-date existing detection systems. Then the most effective features of the existing detection systems are extracted, modified and combined together to develop more powerful detection system called Sequence Number with Rate and Signal Strength detection method (SN-R-SS).

SN-R-SS consists from three phases. First phase is Window Sequence Numbers; to detect suspicious spoofed frames in the network. Second phase is Transmission Rate Analysis; to reduce the amount of the suspicious spoofed frames that are generated from the first phase. Finally, the third phase is Received Signal Strength; this phase is decisive phase because it decides whether the suspicious spoofed frames are spoofed or not. Commview for WiFi network monitor and analyzer is used to capturing frames from the radio channals. Matlab software has been used to implement various computational and mathematical relations in SN-R-SS. This detection method does not work in a real time because it needs a lot of computation.

Published: July 2023

An experimental and numerical study has been carried out to investigate the forced convection heat transfer by clean or dusty air in a two dimensional annulus enclosure filled with porous media (glass beads) between two vertical concentric cylinders. The outer cylinder is of (82 mm) outside diameters and the inner cylinder of (27 mm) outside diameter. Under steady state condition; the inner cylinder surface is maintained at a high temperature by applying a uniform heat flux and the outer cylinder surface at an ambient temperature. The investigation covered values of input power of (6.3, 4.884, 4.04 and 3.26 W), Reynolds number values of (300, 700, 1000, 1500, and 2000) and dust ratio values (density number N) of (2, 4, 6 and 8). A computer program in MATLAB has been built to carry out the numerical solution by writing the governing equation in finite difference method. The local Nusselt number, the average Nusselt number, the contours of temperature field and velocity field were presented to show the flow and heat transfer characteristics. The results show that when clean air flow, the wall temperature gradually increases along the cylinder length in the direction of flow and decrease as Reynolds number increase while it increases with input power. For dusty air flow results show that the wall temperature gradually increases along the axial direction and increase with Reynolds number and with input power, and the maximum reduction in heat transfer will be 30 % for N=8 at Re=2000. Comparison was made between the present experimental and numerical results and it gives good agreement. The experimental and numerical Nusselt number follows the same behavior with a mean deviation of 12%.

Published: July 2023

In this paper, the behavior of spliced steel girders under static loading is investigated. A group of seven steel I-girders were tested experimentally. Two concentrated loads were applied to each specimen at third points and the load was increased incrementally up to the yield of the specimen. Two types of splices were considered; the bearing type and the friction-grip type splices. For comparison, an analytical study was made for the tested girders in which the finite element analysis program (Abaqus) was used for analysis. It was found that the maximum test load for spliced girders with bearing type splices was in the range of (34%) to (67%) of the maximum test load for the reference girder. For girders spliced by using friction-grip type splices, the maximum test load was in the range of (90%) to (99%) of the maximum test load for the reference girder. The analytical results show a good agreement with the experimental results with a difference in maximum deflection at midspan was not more than (15%) at maximum load for all girders.

Desa Liang Ulu mempunyai potensi yang memadai untuk ketahanan pangan. Desa ini mempunyai lahan pertanian yang terbilang cukup luas dan subur, daya dukung alamnya yang masih kondusif, serta budaya dan mata pencaharian sebagian masyarakat desa di sektor agraris. Beberapa hal ini dapat mendukung ketahanan pangan, dengan memanfaatkan tanaman hortikultura sebagai yang ada di Desa Liang Ulu. Tujuan dari progam ini adalah penguatan ketahanan pangan dengan memanfaatkan lahan pekarangan rumah masyarakat. Metode dilakukan dengan dua cara, yaitu identifikasi bibit tanaman yang dibutuhkan dan implentasi penanaman produk holtikultura. Program kerja ini dapat dinyatakan berhasil. Hal ini dibuktikan dengan banyaknya tanaman holtikultura di pekarangan masyarakat Desa Liang Ulu. Namun, program ini tentunya tidak dapat memenuhi seluruh kebutuhan pangan masyarakat. Perlu adanya pendampingan dan dukungan lebih lanjut oleh pemerintah setempat.

Pembelajaran online adalah pendidikan yang memanfaatkan jaringan komputer. Hubungannya adalah bahwa pembelajaran online telah menggantikan pengajaran tatap muka di sekolah selama pandemi saat ini. Karena dapat dilakukan tanpa interaksi tatap muka, maka pembelajaran daring bersifat adaptif. Pembelajaran online adalah metode pendidikan mutakhir yang memanfaatkan teknologi komunikasi dan informasi untuk memungkinkan pembelajaran jarak jauh. Karena fleksibilitas yang ditawarkan ini, siswa dapat berpartisipasi dalam pendidikan mereka kapan saja atau di mana saja. Ada peran yang berbeda bagi guru dan siswa ketika menggunakan pembelajaran daring. Guru memainkan satu peran dalam mengintegrasikan pembelajaran online, sementara siswa memainkan peran lain. Sementara siswa berperan sebagai pencipta pengetahuan, pembelajar mandiri, dan pemecah masalah, guru berfungsi sebagai fasilitator pembelajaran dan mentor untuk biaya mereka. Sementara guru, pakar, dan instruktur berada di banyak lokasi, pembelajaran online memungkinkan siswa untuk berkomunikasi, berinteraksi, dan bekerja dengan mereka baik secara langsung maupun tidak langsung Beberapa perangkat pembelajaran yang ditawarkan oleh Kemendikbud dapat digunakan untuk bentuk interaksi dan komunikasi antara siswa dan guru, antara lain rumah belajar, meja kami, ikando, IndonesiaX, Google for Education, smart class, Microsoft office 365, Quipper school, ruang guru, sekolah Anda, Zenius, dan Cisco Webex.

Published: July 2023

Topological insulators are materials that in bulk mode have band gap such as an ordinary insulator but can protect the conduction mode at the edge or surface, i.e. apart from a simple and insulated metal. These materials are insulator in their bulk modes but are metal at the surface. Topological insulators are developed in two and three dimensions. Recently, compounds of the Bi2Se3 have attracted a huge attention because of existence of a Dirac cone in their surface state, having a suitable bandgap (0.3 eV), and easy santhesis. In this research, we investigate the properties of this material using density functional theory. The main focus is on bulk calculations and surface properties. The band structure of this material is studied in bulk mode without any consideration of spin - orbit interaction. Then a surface of this material is considered and its band structure and density of states are studied. The results show that the surface of this material has a Dirac cone.
A VAR – VECM APPROACH IN EXPLAINING THE INFLUENCE OF SHARIA MONETARY INSTRUMENTS TOWARD INFLATION IN INDONESIA

Published: July 2023

Sharia monetary instruments incorporate monetary control based on sharia principles to assist Bank Indonesia in developing and implementing monetary policy. That’s way, it is expected that sharia monetary policy will create economic stability in Indonesia, one of which is rupiah value stability or inflation control. The goal of this research was to look at the impact of sharia monetary instruments, specifically Sharia Bank Indonesia Certificates (SBIC), Bank Indonesia Sharia Deposit Facilities (BISDF), and Sharia Interbank Call Money (SICM), on Indonesian inflation from 2011 to 2020. This is a quantitative study that explains the relation between the independent and dependent variables. The inflation percentage is the dependent variable, whereas the number of SBIC, BISDF, and SICM is the independent variable.This study used time series data from 2011-2020. The Vector Autoregressive (VAR) or Vector Error Correction Model (VECM) method is used in the analysis. The VECM estimation results reveal that SBIC has no effect on inflation in the long or short term. In the meantime, the BISDF has a large favorable influence on inflation, but only in the short term. Finally, in the long term, SICM has a negative influence on inflation, although in the short term, SICM has no effect on inflation. Furthermore, according to the Granger causality test, only the SBIC and BISDF variables demonstrate bidirectional causality. Meanwhile, unidirectional causality exists between the BISDF and inflation, SBIC and SICM, so do BISDF and SICM.
