Degradation modeling is an effective approach for reliability assessment and predicting of remaining useful life in order to investigate the relation between failure time and Degradation of a system or unit. The possibility of an association between Degradation of the unit during the time and the effects of covariates on Degradation processes should be taken into account in the model to improve the explanatory capabilities of Degradation models. Sometimes, the exact amount of Degradation could not be observed because of time, cost, and measurement tools limitations. Therefore, approximate Degradation values can be compared with a critical threshold. In this paper, the Degradation processes modeled with a generalized linear mixed-effect model in order to take into account the correlation between times. Also, maximum likelihood estimation and Bayesian estimate of parameters are derived.

The concept of very true GE-algebra using very true operator is introduced and its properties are studied to expand the scope of research of GE-algebras. The concepts of simple very true GE-algebra and very true GE-filter are introduced. The characterization of simple very true GE-algebra is discussed, and several properties on very true GE-filter are investigated. Using a very true GE-filter, the quotient very true GE-algebra is constructed, and the uniform and topological space are established.

The linkage between sustainable agriculture, poverty and agricultural extension efforts and their impacts on rural centers in Behbahan Shahrestan has been discussed in this paper. Data were collected from 200 farmers in 40 villages of this Shahrestan. A multi-stage stratified random sampling technique was used for selecting villages and farmers. The findings of path analysis in three different causal models provide the complexity of relationships between variables and environmental Degradation so that there is a causal relationship between poverty and unsustainability. Lack of direct causal effect of use of technology and extension efforts on sustainability in three models indicated the structural and institutional limitations of extension in diffusion of appropriate technologies. Finally, recommendations regarding regional planning with respect to socio-economic characteristics and changing from TOT approach to other alternatives and revising the education programs of extension agents are provided.

Peace is a rare and precious thing that is among the most fundamental human needs and plays an important role in the happiness and health of individuals and society. Feeling peaceful is a major characteristic of every healthy human being as one can obtain growth and perfection in light of peace and calm. The Holy Quran, as the book of guidance for humanity, provides the best prescription for achieving peace. This paper seeks to describe true peace and correct man's understanding of it on the one hand, and investigate the factors that contribute to creation and establishment of peace in heart based on divine teachings. To understand the true meaning of peace, one should bear in mind its distinction from comfort. Also, based on the teachings of the Quran, peace is achieved through paying attention to both material and spiritual needs and if there is a conflict between the two, spiritual needs should be given primacy due to the priority of the spirit. There are different words and phrases in the Quran that include the meaning of peace. They include Tathbit, Fuad, Thabat, Rabt-e Qalb, Sukn, and Sakina. A look into these words in the verses of the Quran reveals that the only origin and source of giving peace to hearts is relation with God, the Almighty. In view of the Quran, there are different factors involved in creation and establishment of peace. They include: faith, Zikr (recitation of prayers), correcting one's view of the world, Tawakkul, (putting one's trust in God), thankfulness, Taqwa (God-fearing), and performing religious rites.
