Moderation Effect of Market Condition on the Relationship between Dividend Yield and Stock Return

This paper examines the existence of moderation effect of market condition on the relationship between dividend yield and stock return in Bursa Malaysia. Results confirm the existence of moderating effect of market condition. However, if the market condition is assumed to have direct impact on the stock return, the tested moderating variable fails to be significant in all forms of market condition. Results also suggest that incorporating moderation variable will improve the explanation power of the model in terms of R-square. In addition, models have been controlled for the size effect of the firms.Moderation Effect; Moderating Effect; Market Condition; Dividend Yield; Stock Return; Malaysia

A statistical model of large P(_T) and large mass production

Generally this thesis deals with application of thermodynamical model to high, energy interactions. The first chapter is an introduction. We give the important definitions and also results needed in subsequent work. In chapter 2 a model incorporating various thermal components is proposed to discuss the production of secondaries having large transverse momentum component (i.e. P(_L) ~ 0). The model is compared to the ISR data of large P(_T) pions. Chapter 3 gives a brief description of experimental situation about the azimuthal, rapidity and transverse momentum correlations. The general treatment of multi-temperature model (MTM) is expressed. Momentum recoil effect is included to fit the same/opposite side momentum correlations data. Some other relevant models are explained in this part for comparison. Finally calculations of average charged particles multiplicity accompanying the trigger particle is shown in this chapter. Chapter 4 considers the transverse mass (m_T) universality and its agreement with MTM. Production of high mass particles and their correlation are investigated in the framework of MTM. Again some possible models of different authors are presented and referenced in here

Examination of anticipated chemical shift and shape distortion effect on materials commonly used in prosthetic socket fabrication when measured using MRI: a validation study

The quality of lower-limb prosthetic socket fit is influenced by shape and volume consistency during the residual limb shape-capturing process (i.e., casting). Casting can be quantified with magnetic resonance imaging (MRI) technology. However, chemical shift artifact and image distortion may influence the accuracy of MRI when common socket/casting materials are used. We used a purpose-designed rig to examine seven different materials commonly used in socket fabrication during exposure to MRI. The rig incorporated glass marker tubes filled with water doped with 1 g/L copper sulfate (CS) and 9 plastic sample vials (film containers) to hold the specific material specimens. The specimens were scanned 9 times in different configurations. The absolute mean difference of the glass marker tube length was 1.39 mm (2.98%) (minimum = 0.13 mm [0.30%], maximum = 5.47 mm [14.03%], standard deviation = 0.89 mm). The absolute shift for all materials was <1.7 mm. This was less than the measurement tolerance of +/–2.18 mm based on voxel (three-dimensional pixel) dimensions. The results show that MRI is an accurate and repeatable method for dimensional measurement when using matter containing water. Additionally, silicone and plaster of paris plus 1 g/L CS do not show a significant shape distortion nor do they interfere with the MRI image of the residual limb

Hands-off and hands-on casting consistency of amputee below knee sockets using magnetic resonance imaging

Residual limb shape capturing (Casting) consistency has a great influence on the quality of socket fit. Magnetic Resonance Imaging was used to establish a reliable reference grid for inter cast and intra cast shape and volume consistency of two common casting methods, Hands-off and Hands-on. Design: Residual limbs were cast for twelve people with a unilateral below knee amputation and scanned twice for each casting concept. Subsequently, all four volume images of each amputee were semi-automatically segmented and registered to a common coordinate system using the tibia and then the shape and volume differences were calculated. Results: The results show that both casting methods have intra cast volume consistency and there is no significant volume difference between the two methods. Inter and intra cast mean volume differences were not clinically significant based on the volume of one sock criteria. Neither the Hands-off nor the Hands-on method resulted in a consistent residual limb shape as the coefficient of variation of shape differences was high. Conclusion: The resultant shape of the residual limb in the Hands-off casting was variable but the differences were not clinically significant. For the Hands-on casting, shape differences were equal to the maximum acceptable limit for a poor socket fit

Prevalence of heat and perspiration discomfort inside prostheses: literature review.

People with limb amputation deal with thermal stresses in their daily activities. Unfortunately, in the majority of this population, all thermal transfer mechanisms, including convection, radiation, evaporation, and conduction, can be disturbed due to the prosthetic socket barrier, decreased body surface area, and/or vascular disease. The thermal environment inside prosthetic sockets, in addition to decreased quality of life and prosthesis use, comfort, and satisfaction, could endanger people with amputation with a high risk of skin irritations. The current review explores the importance of thermal and perspiration discomfort inside prosthetic sockets by providing an insight into the prevalence of the problem. The literature search was performed in two databases, PubMed and Web of Knowledge, to find relevant articles. After considering the review criteria and hand-searching the reference sections of the selected studies, 38 studies were listed for review and data extraction. This review revealed that more than 53% of people with amputation in the selected studies experienced heat and/or perspiration discomfort inside their prostheses. In spite of great technological advances, current prostheses are unable to resolve this problem. Therefore, more attention must be paid by researchers, clinicians, and manufacturers of prosthetic components to thermal-related biomechanics of soft tissues, proper fabrication technique, material selection, and introduction of efficient thermoregulatory systems.This material was based on work supported by the Iran National Science Foundation

The effects of endosulfan on P450 1A gene expression, antioxidant enzymes activity and histopathological alterations in liver of Persian sturgeon (Acipenser persicus Borodin, 1987)

The effects of 14 days exposure to sublethal concentrations of endosulfan (10 and 40 μg L−1) were investigated in mRNA- P450 1A expression, antioxidant enzymes (SOD and CAT) activity and histopathological alterations of Persian sturgeon (Acipenser persicus) fingerlings with weights of 3–5 g. The results illustrated that the relative mRNA- P450 1A expression level significantly increased (P < 0.05) compared to the control group. Highest significant increase (P < 0.05) was observed on the first day, then decreased towards day 14 of exposure. The SOD and CAT activity showed a significant increase in fish exposed to different concentrations up to day 7, then activity decreased on day 14 in fish of all treated groups. Although signs of tissue lesions were observed on day 4, they increased from day 7 and reached the highest level on day 14. The magnitude of all changed studied parameters (gene expression, enzymes and histopathological) follows a concentration-dependent manner. © 2016 Blackwell Verlag Gmb

Comparison of conventional tractors performance during primary tillage in Iran

Primary tillage parameters and their effects on tractor efficiency, fuel consumption management and cost reduction are very important in mechanization.  The main goal of this study was to determine some performance parameters in three conventional tractors Massey Ferguson 285(MF 285), Universal 650 (U650) and John Deer 3140 (JD3140) to primary tillage practices in some area of Iran.  These parameters are important for selecting tractors to set up mechanization program in a large scale.  The sampling method was random in 10 regions with seven replications.  After data gathering, results were analyzed using SPSS software.  Results indicated that average drawbar power for plowing without considering of area and tractor type was 15 kW.  The maximum and minimum drawbar powers were 19.20 kW and 11.10 kW for Esfahan and Fars areas respectively at 1% level significance.  There were significant differences between values of rolling resistance of JD3140 tractor with other tractors at 1% level of significance.  Besides, no significant differences were observed between tractors of U650 and MF285.  Slippage percentage was similar for most areas.  The maximum and minimum slippage was recorded for MF285 tractor in Moghan area and JD3140 tractor in Esfahan area respectively.  The optimum soil moisture was 15% for slippage reduction.  Average Power Delivery Efficiency (PDE) was 25.5%.  It was low in comparison with world standards and requires improvement.  Tractor of JD3140 had maximum fuel consumption (0.012 m3 h-1) as compared to other types of tractor.  Use of the U650 tractor was recommended to farmer and other data can be used for mechanization programs.   Keywords: drawbar power, primary tillage, slippage, primary tillage parameters, rolling resistanc
