The aim of the present work is to study the effect of laser shock peening (LSP) on fatigue life of aluminum alloy (3003-H18) by using different (LSP), single spot, 2-spots with 50% overlap and 3-spots 100% full overlap on the surface to be treated. The effect of laser shock peening (LSP) on the fatigue life were investigated with constant amplitude stress at stress ratio R=-1 at room temperature. The results showed that the fatigue life increment over the life of samples without (LSP) in range (12%) for 1-spot LSP, (18%) for 2-spors LSP and (77%) for 3-spots LSP for aluminum alloy 3003-H18 at 100MPa amplitude stress. Also the results show that the highest fatigue strength was for samples with 3-spots LSP.

The effects of magnetic field on the exciton binding energy and the Phosphorous alloy content in a cylindrical Phosphorous doped GaAs quantum dot are investigated with the geometrical confinement.

All the computations to get the electronic states are performed using variational procedure within the single band effective mass approximation by the magnetic field strength. The effect of strain due to the spontaneous and piezoelectric polarizations is included.

Increased environmental awareness and strictness in emissions regulations have led to development of Warm Mix Asphalt (WMA). The potential of WMA in reducing the energy consumption as compared to Hot Mix Asphalt (HMA) is becoming more and more attractive nowadays. The goals for the WMA are to lower the mixing and compacting temperatures by reducing the viscosity of the binder, and using the same HMA plants to produce mixes that still meet specifications. The benefits of WMA include reduced emissions, decreased energy (fuel) consumption, reduced asphalt oxidation and early traffic opening. Several technologies of WMA are available today such as Aspha-min, Sasobit, Evotherm, WMA-Foam and Asphaltan B. Viscosity of the binder is used to determine its mixing, laying and compaction temperatures.In the present study Brookfield Viscometer is used for determination of the viscosity of bituminous binders with different combinations of additives at different temperatures ranging from 90ºC to 160ºC. Two binders VG 30 and CRMB 55, and two additives Sasobit and Evotherm are used. The results shows that the viscosity of the bituminous binders varies exponentially with the temperature and linearly with respect to the dose of Warm Mix additives and the mixing temperature can be reduced by 20ºC to 25ºC while laying and compaction temperature can be reduced by 10ºC to 15ºC by using these additives.

The focus of this study is to explore EFL teachers’ evaluations and expectations about English language courses as EFL in Iran. In other words, this article aims at creating a new avenue for effective EFL teaching curriculum and syllabus in the Iranian context. Iranian universities offer basic, general, and specific English courses as a part of their program, which are not being very effective. These courses do not promote the students in dealing with their disciplines or programs oriented courses. Even after completion of these courses in three or more semesters, students fail to grasp comprehensive control over the reading materials of their field. This is a common scenario in almost all the universities in Iran. The authors of this paper ventured to study the predicament of EFL courses in some universities. The data were collected through questionnaires from a total of 40 EFL teachers at 8 universities. The research results revealed that the existing English Course syllabus is not tailored appropriately to the needs of the students. It, therefore, suggests that university English courses should be redesigned in assimilating the learners’ need, and course contents should cover the socio-cultural factors of the learners.

Flood discharge is one of important factors in designs and hydrological works. Because of non-facilities and non-hydrometric equipment in basins without statistics or with deficient statistics especially in small watersheds, estimation of maximum instantaneous flood discharge is one of main problems in watershed projects. In this stud with the aim of determination of acceptable method to estimate maximum instantaneous flood discharge in small watersheds, two methods one base to basin area and other based to physiographical feature and precipitation were studied. The results showed that among methods related to basin area, Horton method with residual sum of squares 2.8(RMSE=2.8) and among methods related to basin- physiographical feature and precipitation, curve number with RMSE=20.6 had least error .so, determined as the best methods. FHWA method because of having most amount of RMSE=5924.5 had the least efficiency for determination of peak discharge in this area.

The effect of drying behavior on drying rate and quality characteristics of potato slices in a vacuum- infrared drying system was studied. In this work, the effect of the infrared radiation powers (100, 150 and 200 W) and vacuum levels (20, 80, 140 mm [Hg] and atmosphere pressure) at different thickness (1, 2 and 3 mm) on drying rate, shrinkage percentage and rehydration capacity were investigated. From the study, it was concluded that IR power level has significant effects to processing time and drying rate.The processing time reduced,while drying rates were higher with increased in IR power. Drying rate curve of potato slices at initially time of drying because of surface moisture evaporation in the ascending phase and afterward due to the start of influence of water from within of material to surface descending phase occurs. Also shrinkage percentage increased with increase of sample thickness. In other words, shrinkage was decreased at different thickness with increase of infrared radiation power and vacuum level. It was found that the long period of drying and increase of sample thickness may have contributed to a decrease in rehydration capacity. However, rehydration capacity at temperature 100°C for 3 min was more than temperature 25°C in duration 12 min.

The objective of this study was to investigate the changes in in-vitro dry matter digestibility (IVDMD) of plantain peel (PPL) after its biodegradation with Aspergillus niger and also to determine the effect of degraded PPL on the performance, nutrient digestibility, weights of internal organs , haematological and serum parameters of broiler finishers. A total of 165 unsexed broiler finishers were used. The design was Completely Randomized. Aspergillus niger was used for the biodegradation of PPL. There were five dietary treatments of 33 birds each. There were 0 % inclusion level of PPL, 7% inclusion level of undegraded PPL (UPPL) and 3,5 and 7% inclusion levels of degraded PPL (DPPL).Weight gained was significantly (P<0.05) higher with the birds fed degraded PPL. Feed conversion ratio was significantly (P<0.05) highest in birds placed on 7% UPPL (3.38). There were significant (P<0.05) differences in the digestibility of dry matter, crude protein and crude fibre. Crop, gizzard and abdominal fat were significantly (P<0.05) affected. The values of Packed Cell Volume (PCV), Total Protein, Cholesterol and Glucose were significantly (P<0.05) different in Haematological and serum biochemical parameters. Fungal biodegradation of PPL using A.niger has the potential of enhancing feed intake, nutrient digestibility and the body weight gain of broiler.

The Study examined gender-based labour contribution and decision making role among maize farming households in Lafia Local Government Area, North-central Nigeria. Data were collected using structured questionnaire from 60 households randomly selected and analyzed with descriptive statistics and decision making index (DMI). The results showed that Male members of maize farming households contributed 74% of the total household labour needed for maize production per hectare in the study area. However, labour contribution towards post-harvest farm operations by female farmers was 16% higher than that of male. Male farmers in maize farming households dominated decision making role for all activities (with DMI? l) except for processing (1.6) and consumption (1.6) of farm produce decision activities. Poor income, culturally gender-assigned responsibility, poor access to farm inputs, multiple domestic responsibility were ranked major constraints to women contribution to household farming decisions. In order to encourage greater participation of women in agricultural production and household farming decisions for increased food production and income, efforts should be made towards improving women access to farm inputs and credit facility. Literacy and sensitization progamme on gender issues should be embark upon for the purpose of promoting shared responsibilities.
