This study investigates how the relationship between farmers and buyers affects adoption of sustainable agricultural practices (SAPs) in vegetable sector Chile. Specifically, we focus on dyadic relationships different types buyers, including besides lead firms, intermediaries, wholesalers, which have received little attention scientific literature. Our analysis focuses formal informal contracts...

Superabsorbent polymers (SAPs) play important roles in our daily life, as they are applied products for hygiene, agriculture, construction, etc. The most successful commercially used types of SAPs acrylate-based, which include poly(acrylic acid)s, poly(acrylamide)s, poly(acrylonitrile)s and their salts. acrylate-based have superior water-absorbent properties, but high molecular weight addition ...

This paper examines the relative performance of additive and multiplicative clause weighting schemes for propositional satisfiability testing. Starting with one of the most recently developed multiplicative algorithms (SAPS), an experimental study was constructed to isolate the effects of multiplicative in comparison to additive weighting, while controlling other key features of the two approac...

Superporous hydrogels (SPHs) are different from superabsorbent polymers (SAPs) in that SPHs swell fast, within minutes, to the equilibrium swollen state regardless of their size. The fast swelling property is based on water absorption through open porous structure by capillary force. The poor mechanical strength of SPHs was overcome by developing the second-generation SPH composites (SPHCs) and...

We analyse new data for self-avoiding polygons (SAPs), on the square and triangular lattices, enumerated by both perimeter and area, providing evidence that the scaling function is the logarithm of an Airy function. The results imply universal amplitude combinations for all area moments and suggest that rooted SAPs may satisfy a q-algebraic functional equation. PACS numbers: 05.50+q, 02.10.AB, ...

Frutos de Sapindus saponaria (Sapindaceae), uma planta amplamente distribuída nos trópicos, foram coletados a cada trinta dias, durante seis meses. Estudos usando cromatografia a líquido com detecção por UV e EM (CLAE/UV/ESI-EM) e fragmentações por EM/EM, mostraram que os principais glicosídeos presentes nesses frutos são saponinas (SAP) derivadas dos triterpenos hederagenina e ácido oleanólico...

BACKGROUND Patients undergoing intermediate-risk surgery are typically taken to the ward postoperatively. However, some may develop complications requiring intensive care later. We aimed to evaluate the characteristics of patients undergoing intermediate-risk surgery who required late postoperative admission to the intensive care unit (ICU) and determine the predictors for this. METHODS The s...

OBJECTIVE To determine the prognostic importance of admission time, admission day, admission source, and route of admission, attached devices before admission, diagnosis of patients, and total Simplified Acute Physiology Score (SAPS) II score during admission on intensive care unit mortality rates. METHODS This retrospective study was carried out with 545 patients admitted to adult intensive ...

AIM To perform an external validation of the original Simplified Acute Physiology Score II (SAPS II) system and to assess its performance in a selected group of patients in major Croatian hospitals. METHODS A prospective, multicenter study was conducted in five university hospitals and one general hospital during a six-month period between November 1, 2007 and May 1, 2008. Standardized hospit...

CONTEXT AND OBJECTIVE Acute coronary syndromes (ACS) are a common cause of intensive care unit (ICU) admission. Specific prognostic scores have been developed and validated for ACS patients and, among them, GRACE (Global Registry of Acute Coronary Events) has had the best performance. However, intensive care clinicians generally use prognostic scores developed from heterogeneous populations of ...
