http://ijaers.com/ Open Access international Journal to publish research paper en-us November 2017 Nasriya oil field is located at the Southern part of Iraq, this field is a giant and prolific, so it take a special are from the Oil Exploration Company for development purposes by using 3D seismic reflection. The primary objective of this thesis is to obtain reservoir properties and enhance the method of getting precise information about subsurface reservoir characterizations by improving the estimation of petrophysical properties (effective porosity, P-wave, water saturation and poisson’s ratio). There are five wells in the study area penetrated the required reservoirs within Yammam Formation. The Synthetic seismogram of Nasriya wells were created to conduct well tie with seismic data. These well tie was very good matching with seismic section using best average statistical wavelet. Five main horizons were picked from the reflectors by using synthetic seismogram for wells then converted to structural maps in depth domain by using average velocity of five wells. By using petrel program TWT maps have been constructed from the picked horizons, Average velocity maps calculated from the wells velocities survey data and the sonic log information and Depth maps construction was drawn using Direct time-depth conversion and the general trend of these map was NW-SE. The model of low frequency was created from the low frequency contents from well data and the five main horizons were picked. The seismic inversion technique was performed on post-stack three dimensions (3D) seismic data in Nasriya oil field. http://ijaers.com/detail/3d-reservoir-study-for-yamama-formation-in-nasirya-oil-field-in-southern-of-iraq/ Salman Z.

The Orthogonal Frequency Division Multiplexing (OFDM) is the popular modulation technique for the many wireless communication systems. In the wireless system, the signal transmitted into channel bounces off from the various surfaces resulting in the multiple delayed versions of the transmitted signal arriving to the receiver. The OFDM has trusted to be very effective in mitigating adverse multi-path effects of a broadband channel. The multiple signals are obtained due to the diffraction and reflection of electromagnetic waves around objects .The bit error rate (BER) performance of this type of systems are evaluated in the additive white Gaussian noise (AWGN) channel. The BER performance of the transmission modes are calculated by calculating the bit error rate (BER) versus signal to the noise ratio (SNR) under the Additive white Gaussian noise (AWGN), channel. http://ijaers.com/detail/ber-performance-of-ofdm-system-in-rayleigh-fading-channel-using-cyclic-prefix/ Miss.

Thus a field experiment was conducted in three (3) different planting seasons using three tillage methods (mound, ridge, flat) and four different rates (0t/ha, 2t/ha, 4t/ha, 6t/ha) of wood ash to evaluate the effect of tillage and wood ash on heavy metal; copper (Cu), boron (B) and lead (Pb) content of soil and uptake by castor shoot and seed. Data generated from the study was analyzed using crop start version 7.2 and mean separation was done using least significant difference (LSD0.05). The findings from the study showed that the interactive effect of tillage and wood ash on heavy metals content of soil, castor shoot and seed were significant (P http://ijaers.com/detail/interactive-effect-of-tillage-and-wood-ash-on-heavy-metal-content-of-soil-castor-shoot-and-seed/ Nweke I A, Ijearu S I, Dambaba N http://ijaers.com/uploads/issue_files/3 IJAERS-FEB-2017-43-Interactive effect of tillage and wood.pdf The overdependence on the usage of industrially manufactured soil improved or conventional additives have resulted in unaffordable cost of construction of better infrastructure in Third World and poor countries which are mostly agriculturally dependent across Globe. This study is aimed at studying the mechanical properties of lateritic soil stabilized with mixture of conventional and locally available additives. Soil samples collected from the study area were subjected to laboratory tests (i.e. Grain Size and Atterberg Limits tests) after stabilized with cement, ESA and RHA additives at proportion of 2% to 10% by sample weight. It is observed that the LL, PL and PI values varied from 30.1% to 35.5%, 9.9% to 12.5% and 20.1% to 23.2% respectively for sample A. While LL, PL and PI values varied from 35.2% to 41.5%, 10.8% to 14.5% and 24.4% to 27.1% respectively for sample B. It could be generally observed that PI values reduced while PL values increased for the soil samples after increase in addition of cement additive from 6% to 8%. All the LL, PL and PI values also reduced as the percentage of RHA additive added increased. Soil sample A has group classifications of A – 2 – 6 while soil sample B has A – 7 and tend towards A – 2 - 6 and A - 6 after stabilization. The stabilization process using local additives as partial replacement of conventional one generally improved the soils Engineering properties. Though it is more felt in ESA than RHA. Further research work should be carried out. http://ijaers.com/detail/study-of-mechanical-properties-of-stabilized-lateritic-soil-with-additives/ Elijah O. Abe, Ezekiel A.

This can foster waste to wealth policy in country like Nigeria. The aim of this study is to assess performance properties of a stabilized lateritic soil with a view to obtain a cheap and more effective additive. Soil samples were collected from the study area and subjected to Compaction and California Bearing Ratio (CBR) laboratory tests with the addition of 2%, 4%, 6%, 8% and 10% Rice Husk Ash (RHA) and Egg Shell Ash (ESA). Results showed that MDD, OMC and CBR values varied from 1575Kg/m3 to 1930Kg/m3, 7.55% to 18.50% and 20% to 131% respectively for sample A. And 1566Kg/m3 to 1896Kg/m3, 7.53% to 16.90% and 16% to 98% respectively for sample B. The MDD values decrease with increase in the additives contents due to the replacement of soil by the additives in the mixture, coating of the soil by additives which resulted in large particles with larger voids and density; and addition of the additives which decreased the quality of free silt, clay fraction and coarse materials with large surface areas formed. OMC values also increase as the additives increase, though, that of RHA increases more than that of ESA. This is due to the increase in additives which resulted to increase in the amount of water required in the system to adequately lubricate all the particles in the mixture equally increase. Generally, CBR values also increase with increase in the additives contents. This could be attributed to gradual formation of cementitious compound between the additives and Calcium Hydroxide (Ca(OH)2) present in the soil, thus increase in coarse particles of the soil through cementation. http://ijaers.com/detail/assessment-of-performance-properties-of-stabilized-lateritic-soil-for-road-construction-in-ekiti-state/ Elijah O.

The ZrB2 powder was synthesized by using self-propagating high temperature synthesis (SHS). The samples of different aspect ratios (0.35, 0.5 and 0.65) were made and then sintered at 550oC under continuous argon gas atmosphere in a tubular furnace for 1 hour. The microstructure of the composites had shown that there is no chemical adhesion between Al matrix and ZrB2 reinforcement. Hardness of the composites increased with increase in the amount of ZrB2 reinforcement. The hardness of the composites increased with increase in amount of ZrB2 reinforcement. It was found that the formability stress index increased with the increase of preform fractional density and decreased with the aspect ratio. Relation between various stress ratios, axial strain and relative densities were analyzed. Statistical fitting methods are used on the curve drawn between the axial strain and the stress formability index. The compacts of lower aspect ratio and high initial preform density were found to have a very high fracture strain. http://ijaers.com/detail/some-aspects-of-cold-deformation-studies-of-al-zrb2-composites/ C.

Based on the data from the 2012, Indonesia was ranked at third biggest coffee beans exporter in the world, after Vietnam and Brazil. A coffee land expansion have been done to increase the productivity of coffee beans, however it is not so effective. One of the factors that affect the productivity is a crops planting pattern. A good crops planting pattern will make a good air circulation and it will finally affect to the productivity of coffee beans. We will use a finite volume method to analyze the air flow of coffee plantation based on the soil roughness level, crops planting pattern of the triangular grid and shackle of wheel graphs. The simulation process is carried out by using MATLAB and FLUENT softwares. The result shows that the crops planting pattern of triangular grid and shackle of wheel graphs gives a better air circulation process in the coffee bean plantation. http://ijaers.com/detail/the-air-flow-analysis-of-coffee-plantation-based-on-crops-planting-pattern-of-the-triangular-grid-and-shackle-of-wheel-graphs-by-using-a-finite-volume-method/ Dafik, Muhammad Nurrohim, Arif Fatahillah, Moch.

Iron and sulfur oxidizing bacteria produce capsular (EPS) and colloidal polysaccharides. At present the properties and functional role of EPS are well studied. However, the properties of the colloidal polysaccharides produced by iron oxidizing bacteria have not been sufficiently explored. A new iron oxidizing bacteria Leptospirillum ferriphilium CC was isolated from sulfide ores of Armenia. Its morphological and physiological features have been studied. A colloidal polysaccharide has been isolated with the use of an original method developed by the authors, and its physical and chemical properties have been studied. It has been shown that the colloidal polysaccharide consists of three different monomers- glucose, fructose, mannose.. Investigations with a complex method of optical polarization microscopy and analytical programs allowed determining the size, shape change, perimeter, degree of hydratation and crystallization at 0.07% and 0.04% of polysaccharide concentration. It was shown that the size of a polysaccharide colloidal particle does not much depend on polysaccharide concentration, however, the number of identical colloidal formations is dependent on the concentration of polysaccharide. http://ijaers.com/detail/peculiarities-of-a-colloidal-polysaccharide-of-newly-isolated-iron-oxidizing-bacteria-in-armenia/ Levon Markosyan, Hamlet Badalyan, Arevik Vardanyan, Narine Vardanyan http://ijaers.com/uploads/issue_files/10 IJAERS-NOV-2017-2-Peculiarities of a Colloidal.pdf Global warming and increase of energy consumption issues has encourages architect to design energy efficient building. The most crucial aspect in designing building in warm humid climate is solar irradiance and wind flow. High level of irradiance increase heat gain of the building and it also cause a higher cooling load and cooling energy. More compact the building form, the cooling energy consumption will be less. Compact or bulky building usually consumes less cooling energy than the slim one because it has lower s/v ratio. Thus the bulky form, middle rise wide span building usually uses atrium to help distribute daylight in to every room of the building. Unfortunately the daylight from the atrium brings considerable heat because the solar radiation that hit the horizontal plane is very high and it’s very difficult to minimize solar gain in the roof. This research aims to evaluate the daylight performance of middle rise wide span building in Surabaya. Case study of this research is G-Building of Institute Technology Adhi Tama Surabaya. To evaluate the daylight performance daylight factor of the building was measured by lux-meter and then compared to daylight factor standard for any rooms. Daylight performance of the buildings was found to bear some relations to cooling energy performance and composition of fenestration-opaque roof in atrium. http://ijaers.com/detail/daylight-performance-of-middle-rise-wide-span-building-in-surabaya-case-study-g-building-itats/ Dian P.E.

Beams whose span (L) to depth (D) ratio is reasonably small can be said as a deep beam. Beams with large depth, supported by individual columns, often used as transfer girders in tall buildings, long span structures etc are commonly referred to as deep beams. Deep beams are used for architectural buildings where the span is very large without any intermediate columns such as marriage halls, assembly halls, auditoriums, theatres etc. According to IS456-2000, a beam is said to be as a deep beam when the ratio of effective span to overall depth (L/D) is less than 2.0 for simply supported members and 2.5 for continuous members. The design of such structural elements requires innovative procedures to serve the functionality coupled with durability. In deep beams, the bending stress distribution across any transverse section deviates appreciably from the straight line distribution assumed as in the simple beam theory. So, assumption of “Plane section before bending remains plane after bending” does not become valid and the neutral axis does not lies at the mid depth. In deep beams, the ultimate failure due to shear is generally brittle in nature, in disparity to the ductile behavior and progressive failure with large number of cracks as observed in normal beams. In this paper, flexural strength of M20 and M30 graded concrete deep beams with the addition of a combination of 0%,10%,20% metakaolin as a partial replacement for cement and 0%,2.5%,5% polypropylene fibre is found out and mode of failure is observed for each case. Mix designs for M20 and M30 graded concrete are carried out in worksheets and the proportions of cement, sand, coarse aggregate are calculated based on the tests conducted on cement and aggregates. Cubes are casted and 7 days compressive strengths for those cubes are tested using compressive testing machine and the mix proportions are used. http://ijaers.com/detail/flexure-and-shear-study-of-deep-beams-using-metakaolin-added-polypropylene-fibre-reinforced-concrete/ S.

It demonstrates, in detail, how to employ the MatLab tool so as to search efficiently for the optimal PID controller parameters within a mechanism system. The proposed approach has superior features, including: easy implementation; stable convergence characteristics; and less computational effort. Three phase induction motors has complex mathematical modelling which makes it difficult to design the speed controller. Software PID Tuning Mechanismwas developed herein and used to obtain both the initial PID parameters under normal operating conditions and the optimal parameters of PID control under fully-loaded conditions. The proposed PID controller Tuning Mechanism will automatically tune its parameters within these ranges. In order to prove the performance of the proposed tuning mechanism for the PID controller, a three phase asynchronous motor was modelled in MATLAB, the transfer function was obtained using the software and a controller was designed using PID.

On the one hand, thrust without exhaust is de facto impossible, unless we deny the Law of Action-Reaction, whose evident violation would result in acknowledging the concrete need for a new Physics; on the other hand, it would appear that opportunely shaped resonant cavities, when fuelled with microwaves, deliver a certain thrust, apparently without a detectable exhaust. In this paper, instead of discussing the validity of the various tests to date independently carried out, speculating about misleading side-effects or inadequate instrumental precision, we simply suppose that the thrust may be an actual phenomenon. Therefore, we try to provide a qualitative explanation to the functioning of the alleged reactionless device, by resorting to a theory elsewhere proposed and herein briefly discussed. http://ijaers.com/detail/is-the-em-drive-a-closed-system/ Carmine Cataldo http://ijaers.com/uploads/issue_files/26 IJAERS-NOV-2017-30-Is the EM-Drive a Closed System.pdf This thesis is a reflection seismic study (structural and stratigraphic) of a (1200) km2 area located in the eastern south of Iraq within the administrative border of the province of Maysan province .The study area was interpreted by using 3-D seismic data from Oil Exploration company. The reflector is detected Within Mishrif Formation which is deposited during the Cretaceous age .The seismic interpretation of the area approves the presence of some stratigraphic features in the studied Formation. Some distributary mound and flatspot were observed within the study area, but they are not continuous due to the tectonic effects. These activities elements give reasonable explanation for the hydrocarbon distribution in the area of study and explain why in Kt-2 is wildcat. The study of seismic facies of the picked reflectors distinction type of seismic configuration is progressive seismic facies characterized by Mishrif Formation. Using seismic attribute techniques including instantaneous frequency showed low frequency in areas of hydrocarbon accumulations. Instantaneous phase attribute was detected seismic sequence boundaries, sedimentary layer patterns and regions of onlap and top lap patterns. Amplitude attribute showed that low amplitude value which probably the area of hydrocarbon reservoir. http://ijaers.com/detail/3d-seismic-study-to-investigate-the-structural-and-stratigraphy-of-mishrif-formation-in-kumiat-oil-field-southern-eastern-iraq/ Kamal K.

Rasheed http://ijaers.com/uploads/issue_files/27 IJAERS-NOV-2017-14-3D Seismic Study to Investigate.pdf The mechanism of absorption of excess power of the flow within hydraulic jump has been studied in the article based on theoretical manner. Mathematic model of hydraulic jump has been investigated by taking additional water body (mass) in hydraulic jump zone as basic. Theoretical research has shown that main part of excess power is discharge for rotation of additional water mass and a formula has been obtained to make calculation thereof. The article also has provided a formula for calculating the portion of flow energy needed for overcoming friction resistance emerged in bed bottom. Because of conducted studies, formulas have been suggested for calculating hydraulic jump length occurred in flat and uneven beds. Obtained formulas have been mutually analyzed with results found by other researchers. http://ijaers.com/detail/hydraulic-jump-on-smooth-and-uneven-bottom/ A.
