Background: The Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire is the most validated and the most specific tool for measuring the quality of life of patients with constipation. Over 120 million people live in countries whose official language is Persian. There is no reported Persian version of the PAC-QOL questionnaire yet. The aim of this study was to translate and ...

The relationship between perceived athletic competence (PAC) and physical activity (PA) in children with developmental coordination disorder (DCD) is still unclear. This study investigated differences in PAC and PA between, and within, a group of children with DCD that were clinically referred (n = 31) and a group of control children (n = 38), aged 7-12 years. All children were categorized in f...

taining polyaminocarboxylate (pac) ligands (Ru-pac) is of continuing interest. The donor character of the pac ligand is comparable with that of many biological enzymes which make use of the carboxylate and amine donors from amino acids to bind to a metal centre. The pac ligand can form very stable 1:1 (metal : ligand) complexes with ruthenium. Early studies (1-3), later confirmed by crystallogr...

We generalize the notion of a projective profinite group to a projective pair of a profinite group and a closed subgroup. We establish the connection with Pseudo Algebraically Closed (PAC) extensions of PAC fields: Let M be an algebraic extension of a PAC field K. Then M/K is PAC if and only if the corresponding pair of absolute Galois groups (Gal(M),Gal(K)) is projective. Moreover any projecti...

The interaction behaviours between components of polyacrylate (PAc)/poly(ethylene oxide) (PEO) and lithium perchlorate (LiClO(4)) were investigated in detail by Attenuated Total Reflectance (ATR)-Fourier Transformed Infrared (FTIR) spectroscopy. Solution cast films of the PAc/PEO and PAc/PEO/LiClO(4) were examined. No obvious shifting of the characteristic ether and ester group stretching modes...

In reinforcement learning, the classic objectives of maximizing discounted and finite-horizon cumulative rewards are PAC-learnable: There algorithms that learn a near-optimal policy with high probability using finite amount samples computation. recent years, researchers have introduced corresponding reinforcement-learning beyond rewards, such as specified linear temporal logic formulas. However...

As a pretreatment for membrane microfiltration (MF), the use of powdered activated carbon (PAC) with a particle size much smaller than that of conventional PAC (super-powdered PAC, or S-PAC) has been proposed to enhance the removal of dissolved substances. In this paper, another advantage of S-PAC as a pretreatment for MF is described: the use of S-PAC attenuates trans-membrane pressure increas...

r Res; 70( ritical event in the apoptotic cascade is the proteolytic activation of procaspases to active caspases. spase autoactivating compound PAC-1 induces cancer cell apoptosis and exhibits antitumor activity rine xenograft models when administered orally as a lipid-based formulation or implanted s.c. as a terol pellet. However, high doses of PAC-1 were found to induce neurotoxicity, prompt...
