A new heterogeneous acid catalyst based on a natural resource, Tunisian clay (Clay-H0.5), has been prepared and characterized by FT-IR, FE-SEM, and powder X-ray diffraction (XRD), as well as chemical composition, cation exchange capacity, specific surface area, and pore volume. Acid treatment for 0.5 h enlarged the surface area from 78.24 to 186.10 m2/g and pore volume (PV) from 0.186 to 0.281 cm3/g. The catalytic activity of this material was investigated in ketalization reaction under mild solvent-free conditions. This achieved up to 92% isolated yield for only 10 wt.% of the catalyst.

In this work, the anharmonic extended X-ray absorption fine structure (EXAFS) oscillation of crystalline silicon (c-Si) is presented in terms of the Debye-Waller factor using the cumulant expansion approach up to the fourthorder. The first four EXAFS cumulant has been calculated based on the classical anharmonic correlated Einstein (ACE) model and suitable analysis procedure, in which thermodynamic parameters are derived from the anharmonic effective potential obtained using the first shell near-neighbor contribution approach.

Spirulina is noticed for great applications on food supplements, animal feeds, pharmaceutical, cosmetics, biofuel, fertilizer, etc. Spirulina cultures in wastewaters could enhance the feasibility of commodities due to its ability to reduce the cost of biomass production and remove pollutants in wastewaters. This study investigates the effects of wastewater pretreatment using various aeration periods (i.e. from 3 to 7 days), the supplement of bicarbonate and N:P ratios on the growth of Spirulina sp. to produce protein-rich biomass. The work showed that Spirulina sp.

Any information system that is developed without considering the needs of the user fail to achieve the goals for it stands. Considering that view, the design of a User-centered bilingual website was done as per ISO 13407 guidelines for strengthening the cyber extension activities of the Directorate of Extension (DoE), Kerala Agricultural University (KAU). A usercentered design (UCD) of the website optimizes it around how the endusers want, or need to use it, rather than forcing them to accept it. The website thus developed after prototyping can be a better tool for agriculture extension.

“Commute trips” include those traveling between home and work. There is a broad literature of studies concerning the valuation and treatment of time savings for commute trips, which is discussed in Forkenbrock and Weisbrod (2001) and Litman (2008). There is also a line of research (Madden, 1985 and Zax, 1991) which shows that businesses ultimately end up paying a premium to attract and maintain workers in parts of urban areas where transportation costs to employees are higher.

Health and safety is a vast and expanding subject. New regulations seem to come into force even before the existing legislation is thoroughly adopted by employers. This report has been written to help employers avoid finding out what to do through enforcement action when regulators start asking for documents and procedures that are not familiar. Every endeavour has been made to provide information that is absolutely up-to-date. Fortunately in the UK the regulatory authorities provide for a consultation and lead-in period before the full adoption of changes.

Shiitake mushroom contains several therapeutic actions such as antioxidant and antimicrobial properties, carried by the diversity of its components. In the present work, extracts from shiitake mushroom were obtained using different extraction techniques: high-pressure operations and low-pressure methods. The high-pressure technique was applied to obtain shiitake extracts using pure CO2 and CO2 with co-solvent in pressures up to 30 MPa.
