The study deals with physico-chemical characteristics of groundwater in the environs of Greater Visakhapatnam Municipal Corporation (GVMC), Visakhapatnam district, Andhra Pradesh. The study area covering about 1143 km2 is famous for major industries, often called as Industrial City or Visakha Steel City. Haphazard urbanization, industrialization and improper disposal of solid wastes leading to ...

silver nanoparticles (nps) have been the subjects of researchers because of their unique properties ( e.g., size and shape depending optical, antimicrobial, and electrical properties). a variety of preparation techniques have been reported for the synthesis of silver nps; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods...

Chemical patents contain detailed information on novel chemical compounds that is valuable to the chemical and pharmaceutical industries. In this paper, we introduce a system, NERChem that can recognize chemical named entity mentions in chemical patents. NERChem is based on the conditional random fields model (CRF). Our approach incorporates (1) class composition, which is used for combining ch...

As do many industries, colleges and universities encounter thorny problems in dealing with hazardous wastes. Industry and academia alike are saddled with the rising cost of waste management and face perpetual liability for costs of waste cleanup. Unlike many industries, however, colleges and universities generate small amounts of waste, most, but by no means all of which is generated in laborat...

The use of nicotinic acid derivatives in the field of medicinal, biomedical industries, production of cosmetics, pesticides, agro chemical industries and its biological activities have been studied extensively over the past decades. In this chapter, one of such nicotinic acid derivative called Nicotinic Acid Ethyl Ester (also known ethyl nicotinate, Ethyl 3-pyridinecarboxylate and 3-pyridinecar...

This paper investigates the multistage hybrid flow shop (HFS) scheduling problems using the new bat algorithm. A HFS is the generalisation of flowshop with multiple machines. HFS is one of the important scheduling problems that represent many industries like iron and steel, chemical, textile and ceramic industries. The HFS scheduling problems have been proved to be NP-hard. A recently developed...

This paper analyzes the modeling process by means of a eld study in the chemical industries. A diversi ed set of experienced modelers from two di erent countries have been interviewed using a case study approach. The interviews focussed on the modeling process. Other issues like life-cycle perspectives and the use of modeling in the process industries were treated as well. The information has b...

This study analyzes the exchange rate pass-through into China aggregate import prices and prices of eleven industries under the HS classification. Chinese monthly data from July 2005 to July 2015 are used. Bounds test finds that all industries have co-integration relationship, with the exception of footwear and headgear products (HS12) and transport equipment (HS17). We have researched the shor...

The process industries — those firms that add value by mixing, separating, forming andror chemical reactions by either batch or continuous mode — continue to lag behind the discrete industries in the identification and implementation of Ž . effective production and inventory management P&IM techniques. A contributing factor is that the process industries have traditionally been lumped together ...
