Can we re-used the reinforcement extracted from demolition of a building for the construction of a new building?

In G Power - which should I use for a hierarchical regression with continuous variables? t test - linear multiple regression: fixed model, single regression coefficient OR OR f test - linear multiple regression: fixed model, R2 deviation from zero. What is the difference?

I have read out a lot of paper about bendable concrete. please anyone can help me make concrete elastic or introducing shape regain able property in concrete after bending.

Based on the model in the attachment, how many predictors to be keyed in to G*Power? I received different answers from others:

A) 3 - identify the DV that has most arrows pointing to it. Both C1 and C2 have 3 predictors, it will be considered 3 predictors only for G*Power.

B) 6 (3 predictors for C1 + 3 predictors for C2 = 6 predictors)

C) 8 (Antecedents to mediator B1 are considered, therefore 6 predictors in the answer B plus 2 predictors A1 & A2 = 8 predictors)

D) None of the above

I have read some articles and books but they seldom further explain on this. Appreciate it if you could share your answer with some references that support the answer. Thank you so much.

In my g power ap which linear multiple reg should I tick? One says R squared deviation from zero and the other says R squared increase. I'll be doing a Hierarchical multiple regression analysis with a health beliefs questionnaire as my dependent variable and I'll have several independant variables (categorical and continuous) such as sex, education level, and the response to several different questions, and scores on a characteristics scale.

Apart from ImageJ, are other other other software for image analysis one can use online?

Dearest:

I will appreciate your help. I'm doing a metanalysis and the paper reports 95%CI instead SD. Is it possible to calculate SD from 95%CI and mean??

And,

Is the least-square mean the same than mean difference in an intervention study?

Scalability of process innovations involving mechanical activation is fundamental to their commercial exploitation. Can someone help to know what is the largest capacity/size available for commercially available attrition mills (bead mills), eccentric vibratory mills, planetary mills and jet mills.
