Tri-flo cyclone,as a dense-medium separation device,is one of the most typical environmentally friendly industrial techniques in the coal washery ***,no detailed investigation has been conducted to explore the effectiveness of tri-flo cyclone operating parameters on their representative metallurgical responses(yield and recovery).To fill this gap,this work for the first time in the coal processing sector is going to introduce a type of advanced intelligent method(boosted-neural network"BNN")which is able to linearly and nonlinearly assess multivariable correlations among all variables,rank them based on their effectiveness and model their produced *** assessments and modeling were considered a new concept called"Conscious Laboratory(CL)".CL can markedly decrease the number of laboratory experiments,reduce cost,save time,remove scaling up risks,expand maintaining processes,and significantly improve our knowledge about the modeled *** this study,a robust monitoring database from the Tabas coal plant was prepared to cover various conditions for building a CL for coal tri-flo ***-known machine learning methods,random forest,and support vector regression were developed to validate BNN *** comparisons indicated the accuracy and strength of BNN over the examined traditional modeling *** a sentence,generating a novel BNN within the CL concept can apply in various energy and coal processing areas,fill gaps in our knowledge about possible interactions,and open a new window for plants’fully automotive process.

Purpose: Having the child with Cerebral palsy is a very stressful experience for the family that could affect daily patterns and routines, habits, needs and occupational performances of all family members specially mothers. This study aimed to investigate life balance of mothers of children with Cerebral palsy (MCCPs) based on the Life Balance Model. Method: Fifty MCCPs aged 3 to 9 years with sample convenient method participated in this descriptive and cross-sectional study. The Severity of cerebral palsy was determined by Gross Motor Function Classification System (GMFCS) and Manual Ability Classification System (MACS) and the life balance of mothers was evaluated by Persian version of the LBI (P_LBI). The collected data were evaluated and analyzed using SPSS software. Results: The total mean score of LBI and its subscales showed that there is no balanced or very balanced life in mothers and they could be categorized to unbalanced (n = 21) and very unbalanced (n = 29). The total mean score of LBI was 1.46. χ2 test revealed statistically significant difference between two categories (unbalanced and very unbalanced) of mothers regarding GMFCS level (p = 0.009). Also, the total mean score of LBI and its subscales showed no significant difference between two categories (unbalanced and very unbalanced) regarding mother job and age and child age (p > 0.05) but it has significant difference regarding mother education (p = 0.009). Evaluation of the results of LBI and its different subscales indicated that the life balance at balanced or very balanced levels was not observed in any of the studied mothers, and they could be categorized in 2 groups of unbalanced (21 mothers ) and very unbalanced (29 mothers) (Table 2). Discussion: Based on the result of this study, mothers of Cerebral Palsy do not experience balanced life and this feeling of unbalance is related to the level of their child’s disability. Thus, it is necessary to consider this fact in family-centered evaluatio
