BACKGROUND Sugarcane distilleries use molasses for ethanol production and generate large volume of effluent containing high biological oxygen demand (BOD) and chemical oxygen demand (COD) along with melanoidin pigment. Melanoidin is a recalcitrant compound that causes several toxic effects on living system, therefore, may be treated before disposal. The aim of this study was to isolate a potent...

pisciculture, especially in countries which are unable to develop their marine resources, is a desired to provide part of their food and protein needs. this study aims at investigating welfare impacts of energy subsidy removal on fish producers in fars province. to achieve the objective, cross-sectional data obtained from fish producers of fars province in 2010 was used. cost, input demand and ...

Whereas a large number of empirical studies have been devoted to analysing consumer demand for specific products, much less attention has been paid to the household’s demand for product variety (the number of different products consumed in a specific time period). This paper analyses consumer demand for food variety in Germany. The econometric analysis of 4.632 household in 1995 suggests, that ...

This paper investigates the effect of price variations on the diet composition in Britain. It describes the dynamics of food demand in relation to food prices over time using data from the British National Food Survey (NFS) covering the period 1975-2000. Demand elasticities with respect to price elasticities are estimated by solving a quadratic almost ideal demand system (QUAIDS) model controll...

The greater consciousness awakened in recent years on healthy and organic has led to increase “natural” products demand worldwide. The quality and high content on bioactive compounds have consolidated their penetration in cosmetic and food market, showing great potential within the pharmaceutical sector too. For this reason, food, cosmetic and pharmaceutical sectors have been forced to develop ...

The grain output of China increased continuously for 11 years from 2004 to 2014, effectively ensuring security of the country’s food supply. At the same time, rapid advancement of urbanization and industrialization generated marked changes in the food consumption patterns of residents, and supply-demand structural problems, such as the variety, quality and region of grains, became increasingly ...

Purpose – The purpose of this paper is to investigate dynamic food demand in urban China, with use of a complete dynamic demand system DLES-LA/DAIDS, which pushes forward the techniques of demand analysis. Design/methodology/approach – We employ a transitionary demand process and develop a new approach of complete demand system with a two-stage dynamic budgeting: an additively separable dynamic...

The US market size of chemical sensors is projected to increase 8.6% annually to reach $6 billion in 2014. This growth will be sustained especially by high demand of biosensors for medical applications such as glucose monitoring, biomarker detection for infectious disease and cancer diagnosis. In addition, there will be strong demand in biodefense, environmental monitoring, food, and pharmaceut...

Session title: Agriculture and Energy: new direct and indirect links can lead to unintended consequences The food commodity price boom of 2003-08 was the most notable in the last several decades. It substantially impacted global economic activity. It affected developing nations by impacting real output, the balance of payments, government budgetary positions and most importantly the well being ...

Current world population is expected to reach 10.5 billion by 2050 (UN March, 2013), further adding to global food security concerns. This increase translates into 33% more human mouths to feed, with the greatest demand growth in the poor communities of the world. According to Alexandratos and Bruinsma (2012), food supplies would need to increase by 60% (estimated at 2005 food production levels...
