"Green analytical chemistry" (GAC) succeeded to become an eco-friendly environmental crucial area in the field of analytical chemistry targeting at the chemical processes' and products' optimization regarding to material consumption, generation of waste and intrinsic safety, toxicity and environmental burdens. For an expressive comparison, an electro-analytical in-line potentiometric selective ...
This study identifies and analyses the occupational risks associated with solid waste management practices in the informal enterprises of Gweru. Many concerns have been raised about the potential harm from waste to the environment and the general public, but the risks and consequent costs of occupational hazards in waste management have received little attention in the rush to adopt or adapt te...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
the purpose of this study was comparison of applicability of tertiary treatment of tehran domestic sewage with organic and inorganic coagulants or a combination of them. the far test procedure was applied utilizing: alum, polyelectrolyte wt 2600, anionic polyelectorlyte wt 3000, and nonionic polyelctrolyte wt 2690 as organic coagulants (products of calgon). the combination of lime with each of ...

Demand of gelatin for food and pharmaceutical application is increasing because it is one of the most widely used food ingredients. Fish gelatin represents one of the important types of gelatin from other sources other than mammalian gelatins and it may thus be considered as an alternative to mammalian gelatin for use in various food and pharmaceutical applications. The main objective of the st...
radiation therapy is considered as one of the main methods in cancer treatment. in this method, determination of exact location and geometric properties of tumor is necessary for treatment planning that leads to increased accuracy and output of treatment and reduction of healthy tissue dose. for this purpose, the aim of the present study has been physiological transmission of gallium as a pharm...
scented rose species are very important in the genus rosa due to their use in highly-prized essential oil production and as garden roses. the fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. a comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly damask r...
Data-mining of Reaxys and network analysis of the combined literature and in-house reactions set were used to generate multiple possible reaction routes to convert a bio-waste feedstock, limonene, into a pharmaceutical API, paracetamol. The network analysis of data provides a rich knowledge-base for generation of the initial reaction screening and development programme. Based on the literature ...
