AbAnbaar, lake, pool have been made to provide drinking water supply in Iran and other countries. However access to water was not same, but all of them have one thing in common, the storage of water. Haj KazemAbAnbaar was located in Maghlovak district which have made in Ghajar dynasty. This structure are include reservoir, stairway, Pa Shir, Sar Dar (portal) and two Bad gir (Windward). Reservoir capacity is 1870 m3and rectangle shape, which build from east to west. Tall portal have eight meter height and decorated with Maegheli (Islamic calligraohy). Date analysis has been indicated that excavation and construction of this AbAnbaar was done by Rikhtai method (pouredi.e made of poured lime-plaster) and while digging out, its ceiling was constructed. The construction material used for abanbars were, slaked lime mortar,Saruj ( the type of plaster most commonly used called sarujm is a compound from six part clay, four parts lime, one part ash), stone, wood and AjorAbAnbaari( special bricks for construction of cistern). The roof of the reservoir has constructed barrel-vault and roof of the stairway constructed with two incrustration and Taghahang (kind of vault). This building have SaghaKhane and Moazeneh(on top of the portal there is a place which called Moazeneh). This study has been taken by data libraryand conducting field studies of AbAnbaar plan with triangulation method and technology of construction.

Motivation plays an integral role in any kind of learning in general and consequently language learning in particular. Demotivation,the other side of motivation (Dornyei, 2001a), is regarded as a very significant factor in language learning. As Dornyei (2001b) postulates in second language learning ,demotivation has a central role and more studiesare required to be undertaken in this regard(p. 5). However, there is a dearth of research in demotivation in both EFL and ESL contexts.They are categorized into three majorfields: Causes related to a) instructors, b) learning/teaching context, and c) learners.

In this Paper, we introduce the notions of (m, n)-Upper Q- fuzzy subgroups, studied some properties of them and discussed the product of them.

Four new cationic surfactants based on sulphonamide were synthesized. Their chemical structures were confirmed using, FTIR, H NMR spectroscopic analyses. The surface active properties of the synthesized surfactants were calculated from surface tension measurements at different temperatures .The performance of these surfactants as corrosion inhibitors for X-65 type carbon steel in oil wells formation water under H2S environment was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The obtained results showed that the percentage inhibition efficiency (?%) was increased by increasing the inhibitor concentration until the critical micelle concentration (CMC) reached. Also, it was found that inhibition efficiency was increased by increasing both molecular size of the surfactant and introducing ethylene oxide units in the surfactant molecule. The data obtained from (EIS) was analyzed to model the corrosion inhibition process through equivalent circuit. Finally, the nature of the protective film formed on carbon steel surface was examined by SEM and EDX techniques.

Wavelet is a recently developed mathematical tool for many problems related to science and engineering. Wavelet also applied in numerical analysis and estimation. In this paper, A survey of Haar wavelet methods to solve PDEs is presented. Moreover, the use of Haar wavelets is found to be accurate, simple, fast, flexible, convenient, computationally attractive.

In tandem with the impending full liberalization of global economy and Basel III requirements in 2015, most commercial banks worldwide might encounter the risks of being taken over by larger bank on account of full liberalization. Therefore, it is imperative for commercial banks to be in the know about the macroeconomic factors that might affect their total assets. In this dissertation, macroeconomic determinants of total assets volume for commercial banks in Malaysia was scrutinized in 2008 – 2010 intervals (post 2008 financial turmoil) via quarterly data through multi-variate single-equation regression method and correlation. Regression results advocate that all the macroeconomic determinants in this thesis have statistically significant impact on total assets of the banks except Foreign Direct Investment (FDI). The empirical findings demonstrate that Base Lending Rate (BLR) together with Foreign Exchange Rate (FER) are negatively interrelated to total assets of the banks whilst FDI has positive relationship with the same dependent variable (DV). The most influential factor against total assets of the banks is BLR. Albeit correlations techniques in this paper signify that BLR, FER as well as FDI have not significantly explained the variations in total assets of the Malaysian banking sector, it is noteworthy that the empirical findings produce similar results as regression methods.

One of the most important factors for agricultural mechanization is management of repair and maintenance costs. Today, tractor is one of the main sources of power in agriculture. The engine overhaul cost is the most rates of repair and maintenance costs. Suitable and high quality engine oil consumption is a more effective factor on engine life increasing. The Nano-science is a new effective method to improving the quality of engine oil and controlling of costs. This study was carried to evaluate the impact of Nano-diamond as an engine oil additive on increasing the oil quality and wearing reduction in the engine oil components. For this purpose, 10 Massey Ferguson 399 tractors were selected from the common tractors in Iran and were classified in two groups. The Nano-diamond as an oil additive material was added to engine oil in one group and was used pure engine oil (without adding any additive) in other one. Then the oil sampling were carried on all tractors engine oil at 50, 100 and 120 hours service time durations and elemental analysis were completely performed on samples. The data were analyzed by SPSS software. Results showed a significant difference at 5% level, between the two groups based on the life oil additives as well as the quantity of erosion particles. The results showed that it is effective to increasing of engine lubricant oil quality as well as reducing of erosion particles quantity, when this additive is used whit 1% concentration based on weight in MF 399 engine lubricant oil tractor. Additionally, resulting from hard Nano-diamond structure, some of the large ferrous particles observed that their quantities have been decreased gradually.

Competitive advantage enables maintaining and improving an organizational position relative to its competitors in the market. Reverse logistics is reportedly a tool for attaining and retaining competitive advantage for manufacturing businesses. In Pakistan different manufacturing industries have employed formalized practices of reverse logistics for cost effectiveness and process effectiveness. However, relevant literature is yet not been updated with facts how Pakistan’s industries have benefited through reverse logistics. This study therefore took initiative of taking reverse logistics as an independent variable to check its effect on competitive advantages that industries in Pakistan targeted. It hypothesized that formalized and standardized programs of reverse logistics were means to achieve cost and process effectiveness. Collecting and analyzing reliable data and needful regression and correlation tests, it discovered a positive relationship between its selected variables. Substantiating its hypothesis, the study contributed empirical findings that formalize programs of reverse logistics remained a key factor for gaining competitive advantages for industries in Pakistan. Thus it recommended encouraging formal reverse logistics programs for manufacturing industries.

The Joint Admission and Matriculation Board (JAMB) is making a frantic effort in stamping out widespread examination malpractices, which has threatened its credibility for many years. To this the board is considering introducing e-exams for the Unified Tertiary Matriculation Examination (UTME) in Nigeria amidst a low level of computer literacy, Information Technology (IT) infrastructure and epileptic power supply in Nigeria. This research sets out to examine the modalities and viability of this venture, thereby suggesting a workable platform; a means of achieving this implementation.

Sequence stratigraphic analysis carried out on the XP field, Greater Ughelli Depobelt, Niger Delta, revealed three sedimentary sequences within the intervals penetrated by three wells studied in the field. Well logs and biostratigraphic data integrated helped in the identification of three major Maximum Flooding Surfaces (MFS1, MFS2, MFS3) recognized between the intervals of 3840- 3080m (aged 31.3- 26.2Ma) and three sequence boundaries designated SB1, SB2 and SB3, between 4232m and 3140m (aged 32.4 – 27.3Ma). The Maximum Flooding Surfaces were recognized using intervals containing high abundance and diversities of three index fossils (Uvigerinella 8, Bolivina 27 and Alabamina 1) which represent the three regional marker shales identified in the field. The erosional surface coincides with intervals that are barren in faunal activity and also corresponds with the coastal deltaic paleobathymetric depth interpreted as Sequence Boundaries. The sequences depict sediments that were deposited between Early to Late Oligocene period in water depth ranging from coastal deltaic to neritic environments. Three depositional patterns resulting from regression and transgression recognized include progradation, retrogradation and aggradational packages with associated systems tracts. The systems tracts form good reservoirs with prospects in the field.
