An animal experimental study of porous magnesium scaffold degradation and osteogenesis BJMBR
Liu,Y.J.; Yang,Z.Y.; Tan,L.L.; Li,H.; Zhang,Y.Z..
Our objective was to observe the biodegradable and osteogenic properties of magnesium scaffolding under in vivo conditions. Twelve 6-month-old male New Zealand white rabbits were randomly divided into two groups. The chosen operation site was the femoral condyle on the right side. The experimental group was implanted with porous magnesium scaffolds, while the control group was implanted with hydroxyapatite scaffolds. X-ray and blood tests, which included serum magnesium, alanine aminotransferase (ALT), creatinine (CREA), and blood urea nitrogen (BUN) were performed serially at 1, 2, and 3 weeks, and 1, 2, and 3 months. All rabbits were killed 3 months postoperatively, and the heart, kidney, spleen, and liver were analyzed with hematoxylin and eosin (HE)...

Are Consumers Willing to Pay More for Biodegradable Containers Than for Plastic Ones? Evidence from Hypothetical Conjoint Analysis and Nonhypothetical Experimental Auctions AgEcon
Yue, Chengyan; Hall, Charles R.; Behe, Bridget K.; Campbell, Benjamin L.; Dennis, Jennifer H.; Lopez, Roberto G..
This study used and compared hypothetical conjoint analysis and nonhypothetical experimental auctions to elicit floral customers’ willingness to pay for biodegradable plant containers. The results of the study show that participants were willing to pay a price premium for biodegradable containers, but the premium is not the same for different types of containers. This article also shows the mixed ordered probit model generates more accurate results when analyzing the conjoint analysis Internet survey data than the ordered probit model.

Are consumers willing to pay more for biodegradable containers than for plastic ones? Evidence from hypothetical conjoint analysis and nonhypothetical experimental auctions AgEcon
Yue, Chengyan; Hall, Charles R.; Behe, Bridget K.; Campbell, Benjamin L.; Dennis, Jennifer H.; Lopez, Roberto G..
This study utilized and compared hypothetical conjoint analysis and non-hypothetical experimental auctions to elicit floral customers' WTP for biodegradable plant containers. The results of the study show that participants were willing to pay a price premium for biodegradable containers but the premium is not the same for different types of containers. This paper also shows the mixed ordered probit model generates more accurate results when analyzing the conjoint analysis internet survey data than the ordered probit model.

Characterization of brewery waste water and evaluation of its potential for biogas production CIGR Journal
Murunga, Sylvia Injete; Mbuge, Duncan Onyango; Gitau, Ayub Njoroge; Mutwiwa, Urbanus Ndungwa; Wekesa, Ingrid Namae.
The issue of global warming and climate change is strongly receiving public attention and has become a major environmental concern both nationally and internationally. Brewing industries are among the largest consumers of water and the largest source of organic effluent mostly from the brewing, cleaning, and cooling processes which must be treated to allowable levels to reduce environmental pollution. Close to 10 L water is used for every 1 L beer that is brewed, though the amount of water in the final beer is small. A study was undertaken to characterize and assess the variations in the quality of untreated brewery waste water. Samples from different process streams including brewing line, clean in place line and mixing line from two brewing industries in...

Effect of the degree of acetylation, plasticizer concentration and relative humidity on cassava starch films properties Ciênc. Tecnol. Aliment.
SCHMIDT,Vivian Consuelo Reolon; BLANCO-PASCUAL,Nuria; TRIBUZI,Giustino; LAURINDO,João Borges.
Abstract The objective of this study was to develop films with reduced hygroscopicity and improved mechanical properties from acetylated cassava starch. For that, an acetylation procedure using acetic anhydride as the esterification reagent was performed, resulting in starch acetates with degrees of substitution (DS) of 0.6 (S0.6) and 1.1 (S1.1). Twelve films formulations were studied: native cassava starch (S), starch acetate S0.6 and S1.1, with two glycerol concentrations (0.25 g.100 g-1 (25) and 0.30 g.100 g-1 (30)). The films were conditioned at the relative humidities (RH) of 58% and 75% for 96 h before characterization. Water vapor permeability, water solubility, water sorption isotherms, microstructural analyses, and mechanical properties in...

Improved biological performance of magnesium by micro-arc oxidation BJMBR
Ma,W.H.; Liu,Y.J.; Wang,W.; Zhang,Y.Z..
Magnesium and its alloys have recently been used in the development of lightweight, biodegradable implant materials. However, the corrosion properties of magnesium limit its clinical application. The purpose of this study was to comprehensively evaluate the degradation behavior and biomechanical properties of magnesium materials treated with micro-arc oxidation (MAO), which is a new promising surface treatment for developing corrosion resistance in magnesium, and to provide a theoretical basis for its further optimization and clinical application. The degradation behavior of MAO-treated magnesium was studied systematically by immersion and electrochemical tests, and its biomechanical performance when exposed to simulated body fluids was evaluated by...

Nitrogen efficiency in oat yield through the biopolymer hydrogel AGRIAMBI
Scremin,Osmar B.; Silva,José A. G. da; Mamann,Ângela T. W. de; Mantai,Rubia D.; Brezolin,Ana P.; Marolli,Anderson.
ABSTRACT The retainers of water in the soil can favor nitrogen (N) use efficiency in oat yield. The aim of the study was to determine if the conditions of use of the biopolymer hydrogel increase the fertilizer-N use efficiency in oat yield in succession systems of high and low residual-N release. In each succession system (soybean/oat, corn/oat), two experiments were conducted in 2014 and 2015, one to quantify biomass yield and the other to estimate grain yield and lodging. The design was randomized blocks with four replicates in a 4 x 4 factorial scheme for hydrogel doses (0, 30, 60 and 120 kg ha-1), added in the furrow with the seed, and N fertilizer doses (0, 30, 60 and 120 kg ha-1) applied in the fourth-expanded-leaf stage. The use of hydrogel...

Preparation and evaluation of a biomimetic scaffold with porosity gradients in vitro Anais da ABC (AABC)
Wang,Qianbin; Wang,Qiguang; Wan,Changxiu.
A novel biodegradable scaffold based on mimetic a natural bone tissue morphology with a porosity gradient structure was prepared in this paper. The result of surface morphology indicated that a graded porous structure was formed in the fabricated scaffold, where the dense layer (0%) was connected with the most porous layer (60%) by a middling porous layer (30%). To evaluate the degradability, graded porous scaffolds compared with homogeneous scaffolds were placed into a Tris-HCl buffer solution (pH = 7.4) for 28 days. It was found that both scaffolds presented the same degradation trend, and the graded porous structure did not change the original degradability of the scaffold. Moreover, the compressive strength of the graded porous scaffold was better than...

Starch Films Added of Açaí Pulp ( Euterpe oleracea Martius) BABT
Pessanha,Kênia Letícia Ferreira; Farias,Mônica Guimarães; Carvalho,Carlos Wanderlei Piler; Godoy,Ronoel Luiz de Oliveira.
ABSTRACT Edible films are an alternative to synthetic materials used for packaging foods. The aim of this study was to develop and characterize films made from cassava starch, freeze-dried acai and glycerol. The films were characterized for thickness, water vapor permeability, water solubility, anthocyanins, antioxidant capacity and mechanical properties. The results indicated a rich edible film in anthocyanins with considerable antioxidant capacity (150.70 micromol Trolox), which can extend the commercial validity of the packaged food and meets the growing demand for biodegradable packaging that tends to reduce the environmental impact. The addition results in a significant effect on the polymer matrix reducing the water solubility and water activity. The...
