Abstract:

Near infrared (NIR) spectroscopy has received a great deal of attention in forest products industry. The physical, mechanical and chemical properties of inorganic materials can be predicted using the NIR spectroscopy and multivariate analysis (MVA). NIR spectroscopy is suitable for quantitative analysis, especially the process monitoring and quality control. The present paper reviews the application of NIR spectroscopy and MVA in the forest products industry, such as tree improvement and silviculture, pulp and paper, lumber products and the online monitoring.

Abstract:

Pharmaceutical industries should apply rigorous QC (quality control) to ensure the consistency, safety, and efficacy of their herbal derived drug-preparations. QC must be performed at every stage of the production line i.e. incoming raw materials, extractions, in-process control, finished products and keeping samples. Due to the complex nature of the chemical content of herbal drugs, two approaches to QC should be taken, that is quantitative determination of the selected marker(s) compound(s), and metabolite profiling.

Abstract:

In recent years, software development has become more large-scaled, complicated, and diversified. At the same time, customer requirement of high quality and shortened delivery has increased. Therefore, we have to manage process quality and control product quality in the early-stage of software development in order to produce highly quality software products during the limited period. In this paper, we conduct multivariate linear analyses by using process monitoring data, derive effective process factors affecting the final product quality, and discuss the significant process factors with respe

Abstract:

Insects are being proposed as an alternative way to ensure world’s food and feed security. Methods to determine edible insect powder’s origin and species will be needed for quality control purposes. Infrared spectroscopy has been extensively used in rapid chemical fingerprinting of food products. The present research explores a new approach to discriminate and classify commercial edible insect powders using attenuated total reflectance mid-infrared spectroscopy combined with multivariate analysis. Infrared spectra of seven commercial edible insect powders from different species (Tenebrio molit

Abstract:

Iodine is a natural trace element that is necessary for the human body. The function of iodine in the human body is the synthesis of thyroid hormones. Iodine deficiency has many negative consequences for the human body. Iodine deficiency is especially dangerous for pregnant women and children. Insufficient iodine in pregnant women increases the risk of miscarriage and birth of a child with cognitive impairment. Iodine deficiency in children has the following consequences: delayed physical development, delayed intellectual development, decreased mental activity, drowsiness, lethargy. Expanding

In this study, we collected and analyzed information on the importance of drug packaging quality to end users and pharmaceutical industry, as an indicator of the process of traceability and originality of drugs. Two surveys were conducted: one among the end users of drugs (252 patients) and the other among professionals working in seven pharmaceutical companies in Serbia. For most end users (82.5%) quality on the packaging of drugs was important, but only 41.8% of them thought that the appearance of the packaging could be an indicator of genuinity of drugs.
