Abstract
Aim: Marital satisfaction can affect both life satisfaction and mental health. Adequate sexual health literacy level can maintain and improve sexual health in individuals. This study aimed to compare the level of marital satisfaction and sexual health literacy in fertile and infertile couples.
Instrument & Methods: This descriptive-cross-sectional study was conducted on 262 couples (including 136 fertile couples and 126 infertile couples) in the north and northwest of Iran during 2020-2021. The data were collected using a demographic characteristics questionnaire, a sexual health literacy for adult questionnaire, and a short-form enrich marital satisfaction scale. The collected data were analyzed using descriptive and inferential statistics in SPSS 26 Software.
Findings: The mean±SD of marital satisfaction in fertile and infertile couples was 36.93±6.58 and 36.05±6.25, respectively and this mean difference was not statistically significant (p=0.121). The mean±SD of sexual health literacy score in fertile and infertile women was 75.69±17.29, and 67.76±20.26 respectively, and it was calculated 76.89±16.22, and 67.66±20.46, in fertile and infertile men respectively. This mean difference was statistically significant (p=0.001) in both groups. Furthermore, the husband’s education level and duration of marriage were regarded as determinants of marital satisfaction among all participants (p<0.05).
Conclusion: The sexual health literacy level in fertile couples is higher than in infertile ones.

Abstract
Aims: This study aims to economic valuation and assess multiple threats to water and soil resources of the Karkheh National Park and Karkheh Protected Area, southwest of Iran.
Methods: Modeling water budget, runoff, soil erosion, and water pollution potential, was performed using the WaterWorld Policy Support System (WWPSS), process-based hydrological model that utilizes remotely sensed and globally available. Eeconomics value has been calculated using the Substitute Cost Method, for 2021.
Findings: The result showed that the southern area of the Karkheh River basin experienced the minimum precipitation, which has led to a decrease in vegetation and an increase in runoff generation in the southern areas. The total runoff generated in the river basin is based on the upstream-downstream relationships from the north to the south was estimated at 81000648 m3.yr-1. The soil erosion rate spiked in the southern area with the vegetation decline and the intensification of runoff could be result in water pollution. Economic valuation represents the real value of water generation in the whole Karkheh National Park and Protected Area was US$ 0.104 million, estimated US$ 6.63 per hectare. In addition, the soil conservation economic value in the entire Karkheh National Park and Protected Area was US$ 9.3 million and US$ 912.2, per hectare.
Conclusion: This information provides valuable awareness into the economic value of natural resources and can help environmental assessors activities related to conservation planning. It assists as a useful tool for emphasizing the economic implications of ecosystem degradation and can help for sustainable management.

Abstract
Option contract is one of the financial derivatives used to manage and control risk. Some doubts have affected its application and usefulness in Islamic financial markets. On some grounds such as wagering on future prices, jeopardizing the capital and acquisition of a windfall wealth, the lack of intention by parties to create a legally binding contract, and the lack of legitimate cause for acquisition, etc., the critics regard the contract as gambling and a void one. This article shall, by contrasting the option contract with gamble in Iranian and English legal systems, conclude that these doubts derive from the characteristics peculiar to option contract, on the one hand, and from the critics’ in acquaintance with option contract and gamble, on the other. Therefore, the similarities between them are only superficial, and the two contracts differ materially from many aspects such as their nature, subject-matter, function, purpose and rules.

Abstract
The aim of this paper is identifying the parameters of for a double-ended magnetorheological damper with different sizes of iron- powders suspended in magnetorheological fluid. There is not any published work in literature about identification of parameters of spherical iron particles with different particle diameters in magnetorheological fluids. Hence, in at first, two different magnetorheological fluids with different diameters of iron particle and same volume percentage are prepared. Then, using a double-ended magnetorheological damper, dynamic displacement tests with harmonic excitation in different frequencies and using different electric currents are conducted. The parametric Spencer model is selected for modeling the damper and identifying its parameters. 10 parameters of this model are identified, using nonlinear least square solver and implementing for damper, using two different magnetorheological fluids in different frequencies and different electric currents. The appropriate polynomials are extracted for parameters that have systematic trends with increasing electric current. experimental hysteresis curves in different electric currents, excitation frequencies and different fluids, it is to assess the capability of Spencer model in regenerating the experimental counterparts. The comparisons of the hysteresis curves obtained from with identified parameters by the experimentally achieved counterparts show that this model has adequate compatibility with experiments in predicting force-velocity hysteresis curves. However, the implemented model has not enough success in predicting the force-displacement hysteresis curves, especially in sharp ends of the curves and force delaying regions.

Abstract
In this paper, the effects of particles size of Magnetorheological Carbonyl iron powder on damping force and energy dissipation capacity for a Magnetorheological double ended type damper is investigated experimentally. Despite of the considerable researches on the effects of particles size on the viscosity of Magnetorheological fluids, sedimentation of fluids and electromagnetic field intensity in damper, there is no a published work about the effects of iron particles size on the damping force amplitude and energy dissipation capacity of double-ended Magnetorheological damper. Therefore, in the present research, two different Magnetorheological fluids were prepared with the same volumetric percentage of % 35 from two different sizes of Iron particles i.e. 40 µm and 63µm and filled into a double ended type damper. The double-ended damper had three electric coils and was tested in different frequencies, different electric currents and 15 mm displacement stroke. The effects of Magnetorheological fluid particles on produced damping force and energy dissipation capacity were analyzed by extracting force-displacement and force-time curves from experiments. The results showed that the maximum amplitude of damping force is increased with increasing the applied electric current on the damper and the amount of this force for fluid with 63µm particles size is slightly higher than that for the fluid with 40µm particles size. However, the energy dissipation capacity of the investigated damper in all excitation frequencies with the all applied electrical currents for fluid with 63µm particles size was considerably higher than that for fluid with 40µm particles size.
