Characterization of clay deposits in the Adrar region, with a view to their valorization in the building materials industry

In the context of sustainable local development of the Adrar region, one of the largest regions in the Algerian Sahara. The search for local useful substances has been initiated by the Algerian state to cover the need for building materials in the construction industry. However, from a geological point of view, the Adrar zone is located in the extension of the primary chain of the Ougarta which separates two sedimentary basins of Reggane and Timimoun, as well as the basin of Sbâa. In this context, an experimental study is focused on the characterization of clay deposits, with a view to their valorization in the construction materials industry (ceramics) sector, with the aim of contributing to the use of local materials

VALORISATION OF FINE DUNE SAND IN ASPHALT CONCRETE

ACLThe south region of Algeria is characterized by a wide surface, a scattered population and a very small ratio of road length per habitant. To allow the development of agricultural, industrial and touristic activities between different cities in the south of Algeria, it is

Reduction of antinutritional factors during Pinus halepensis seeds beverage processing, a focus on phytates and oxalates

The purpose of this study was to screen for the first time, Pinus halepensis seeds for their antinutritional factors (ANFs) and to reduce them through processing. Results of ANF screening showed that Aleppo pine seeds contained negligible amounts of tannins, saponins and alkaloids, and no amylase and trypsin inhibitory activities. However, they contained significant amounts of phytates and oxalates with values of 2.63 ± 0.21% and 1.07 ± 0.09% respectively. A dehulling operation to remove the adhering coat was implemented which contributed to a reduction of 25% of phytates and 46% of oxalates. Soaking seeds were studied and optimized using a Box Behnken experimental design, varying soaking time, temperature, and pH. The desirability study allowed the determination of optimal conditions of 10.6 h soaking time, 57.6 ◦C soaking temperature and 5.54 pH that decreased oxalate and phytate content by 72% and 61% respectively. Production of a plant-based beverage with these optimal process conditions markedly reduced the antinutrient content while maintaining expected dry matter, color, stability and pH

Assessment of recent process analytical technology (PAT) trends : a multiauthor review

This multiauthor review article aims to bring readers up to date with some of the current trends in the field of process analytical technology (PAT) by summarizing each aspect of the subject (sensor development, PAT based process monitoring and control methods) and presenting applications both in industrial laboratories and in manufacture e.g. at GSK, AstraZeneca and Roche. Furthermore, the paper discusses the PAT paradigm from the regulatory science perspective. Given the multidisciplinary nature of PAT, such an endeavour would be almost impossible for a single author, so the concept of a multiauthor review was born. Each section of the multiauthor review has been written by a single expert or group of experts with the aim to report on its own research results. This paper also serves as a comprehensive source of information on PAT topics for the novice reader
