The co-disposal of densified sludge and wastepaper in a co-current flow packed bed gasifier represents new application of the thermal gasification process. Advantages of this technolo a gy include lower costs than other incineration or pyrolysis technologies, simple construction and operation, and the ability to a variety of fuels including agricultural wastes and other b.iomass materials in ad...

Background: Roses have been used since ancient time in rituals, cosmetics, perfumes, medicines and aromatherapy. Turkey, the main rose oil producer in the world, uses R. damascena Mill. for rose oil production. Objective: In this work a comparative survey on chemical composition of essential oils of Rosa damscena Mill. from different locations of Iran has been proposed in industrial scales. ...

In this paper, we consider a network of supplier, producer, retailer and customer which synchronizes a series of inter-related business process in terms of integrated supply chain production inventory model. The whole system is considered for a finite time period with imprecise inventory costs. There are imprecise chance constraints on the transportation costs for both producer, retailer and al...

the present study was focused on supply chain analysis of fresh guava in order to evaluate existing marketing supply chains (sc1: producer - consumer, sc2: producer - retailer - consumer, sc3: producer - commission agent - retailer - consumer, sc4: producer - commission agent - wholesaler - retailer - consumer) for two variety (allahabad safeda and apple guava) of guava. the gross marketing pri...

We describe social, economic, and environmental impacts of a demonstration rural energy project in northeast China. Our ethnographic approach illuminates local circumstances, perspectives, priorities, and power structures that influenced and help to explain project outcomes. The project we studied is a village-scale energy project designed to use locally available corn stalks to generate househ...

The increase in the population of ruminants has resulted an production livestock waste which potential to be a source environmental pollutants as well biogas producer. study ruminant Sidrap Regency was carried out using secondary data from BPS. Biogas is calculated by multiplying with for production, solid matter content, volatile and one year. energy propulsion multiplication per year methane ...

This paper addresses the problem of identifying incompatibilities between two programs that operate in a producer/consumer relationship. It describes the techniques that are incorporated in a tool called PCCA (Producer-Consumer Conformance Analyzer), which attempts to (i) determine whether the consumer is prepared to accept all messages that the producer can emit, or (ii) find a counterexample:...

A kinetic model for predicting biochar, producer gas, and tar formations of top-lit updraft (TLUD) gasification was developed. The three main zones within the TLUD gasifier, pyrolysis, incomplete combustion, reduction reaction zones, were incorporated into sequentially solved. Validated with experimental data, found capable biochar yield on pine woodchips at varying airflow rates, biomass moist...
