ScienceIndex.com is a Nonprofits and Biochemistry Sciences Social Network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Business Sciences, the site has now included the new category Nonprofits and in the Chemistry Sciences the new category Biochemistry. While the Nonprofits section covers organizations not seeking or producing profits, the Biochemistry section covers the chemical substances and vital processes in living organisms.
ScienceIndex.com's Chemistry Category covers the composition, structure, properties, and reactions of substances. Its seven sections include Biochemistry, Food, Inorganics, Materials, Organics, Physics and Toxicology. Users can receive alerts for newly published content in this category by subscribing to ScienceIndex.com's Chemistry RSS feed.
ScienceIndex.com's Nonprofits Section covers organizations not seeking or producing profits. It currently contains 3,343 articles derived from 13 scientific journals. The latest articles in this category are also available through an Nonprofits Section RSS feed. One of the latest additions in this section describes the relationship between network structures and job performance and includes network structure, organizational boundaries, and job performance in its analysis. The authors provide an integration of the current conceptualizations of social capital as they pertain to job performance outcomes by taking a multi-dimensional view of job performance. They discuss the theoretical implications for integrating the social capital, boundary spanning, and network structure literatures, as well as the practical benefits of giving much more precise advice to managers and employees regarding how to use networks to improve performance at work. Another article in this section covers co-creation of nonprofit brand equity. This study examines the brand equity (BE) co-creation of a nonprofit entity, the Finnish Defence Forces military driving school. The authors developed a theoretical BE model further using structural equation modeling in an exploratory manner to reveal whether the BE model of the military driving school is similar from both viewpoints.
ScienceIndex.com's Biochemistry Section covers the chemical substances and vital processes in living organisms. It currently contains 25,494 articles derived from 88 scientific journals. The latest articles in this section are also available through a Biochemistry Section RSS feed. One recently included article in this section covers the determination of colloidal gold nanoparticle surface areas, concentrations, and sizes through quantitative ligand adsorption. The authors demonstrate that the amount of ligand adsorbed is proportional to the AuNP surface area. They conclude that the ligand adsorption-based technique is highly reproducible and simple to implement. Another article investigates the differential effect of curcumin on the nanomechanics of normal and cancerous mammalian epithelial cells. The authors describe the different behavior of two similar cell lines under curcumin treatment and use fluorescence microscopy to identify the microtubules as the cytoskeleton structures responding to curcumin. Since chemotherapeutic drugs exert their effect via the perturbation of the dynamic instability of the microtubule, the cell-specific perturbation induced by curcumin can help in future understanding of drug induced events on the cell behavior.
The Sciences Social Network currently contains over 1.87 million posts distributed among its' 75 categories. 81,585 users monitor 13,409 journals publishing within the scope of the site. Since new science content is discovered in real-time, the delay between original publication and appearance at ScienceIndex.com is no more than two days. The site provides an advanced search feature which suggests up to ten closely related articles for a search and every displayed post.
