Regional equivalent water thickness modeling from remote sensing across a tree cover/lai gradient in mediterranean forests of northern Tunisia

The performance of vegetation indexes derived from moderate resolution imaging spectroradiometer (MODIS) sensors is explored for drought monitoring in the forests of Northern Tunisia; representing a transition zone between the Mediterranean Sea and the Sahara Desert. We investigated the suitability of biomass and moisture vegetation indexes for vegetation water content expressed by the equivalent water thickness (EWT) in a Mediterranean forest ecosystem with contrasted water budgets and desiccation rates. We proposed a revised EWT at canopy level (EWTCAN) based on weekly field measurements of fuel moisture in seven species during the 2010 dry period, considering the mixture of plant functional types for water use (trees, shrubs and herbaceous layers) and a varying vegetation cover. MODIS vegetation indexes computed and smoothed over the dry season were highly correlated with the EWTCAN. The performances of moisture indexes Normalized Difference Infrared Index (NDII6 and NDII7) and Global Moisture Vegetation Index (GVMI6 and GVMI7) were comparable, whereas for biomass vegetation indexes, Normalized Difference Vegetation Index (NDVI), Modified Soil Adjusted Vegetation Index (MSAVI) and Adjusted Normalized Difference Vegetation Index (ANDVI) performed better than Enhanced Vegetation Index (EVI) and Soil Adjusted Vegetation Index (SAVI). We also identified the effect of Leaf Area Index (LAI) on EWTCAN monitoring at the regional scale under the tree cover/LAI gradient of the region from relatively dense to open forest. Statistical analysis revealed a significant decreasing linear relationship; indicating that for LAI less than two, the greater the LAI, the less responsive are the vegetation indexes to changes in EWTCAN; whereas for higher LAI, its influence becomes less significant and was not considered in the inversion models based on vegetation indexes. The EWTCAN time-course from LAI-adapted inversion models based on significantly-related vegetation indexes to EWTCAN showed close profiles resulting from the inversion models using NDVI, ANDVI, MSAVI and NDII6 applied during the dry season. The developed EWTCAN model from MODIS vegetation indexes for the study region was finally tested for its ability to capture the topo-climatic effects on the seasonal and the spatial patterns of desiccation/rewetting for keystone periods of Mediterranean vegetation functioning. Implications for further use in scientific developments or management are discussed

Correlation Between Organizational Memory and Innovative Work Behavior

This study aims to determine the relationship between organizational memory and innovative work behavior. The study was conducted on 100 employees from various levels and positions in a company that produce and trade electronic solar equipment. To measure the organizational memory, we used Organizational Memory Scale developed by Dunhamm (2010) with α=0.75. Then, to measure innovative work behavior, we used Innovative Work Behavior Scale from Janssen (2000) with α=0.80. The results show that there is positive and significant correlation between organizational memory and innovative workbehavior (r=0.35; p<0.01). Hierarchical-regression analysis shows that (1) altogether education level, job type and organizational memory influences 19% of variance in innovative behavior; (2) when these variables are analysed together, only education level shows significant impact on innovative behavior. We discuss theoretical and methodological reasons for these results and offer future direction for research

Fine structure of the dorsal lingual epithelium in Tarentola annularis and Crocodylus niloticus

The present study examined the morphological features, histological and histochemical aspect of the tongue of two reptilian species, Tarentola annularis (family: Gekkonidae) and Crocodylus niloticus (family: Crocodylidea), with different habitats, feeding patterns and behaviours, by light and scanning electron microscope. It was observed, that the bifurcation of the tongue was more visible in Tarentola annularis. Conical and filamentous papillae were observed on the lingual body of Tarentola annularis, while in Crocodylus niloticus both mechanical filiform and gustatory papillae appeared. The lingual mucosa in Tarentola annularis is covered by stratified squamous epithelium and keratinised but in Crocodylus niloticus it is highly folded and more heavily keratinised in the folded region and have a localised thickenings structure resembling taste buds. Mucous glands appeared in Tarentola annularis and compound tubular glands in Crocodylus niloticus. At scanning electron microscopy, abundant microridges and microvilli in both species were exhibited on papillae surface facilitated feeding habits. Histochemically, the tongue of two species is strongly positive for carbohydrate stain but with variable degree with others stains. In conclusion, there is a marked correlation between the structure of the tongue of the present reptilian species, habitats and feeding mechanism of the two species.

Nutrition Tea Club : engaging students in reading scientific papers

Many students do not engage with reading the scientific literature, which is a core skill in undergraduate students. The learning environment has an important impact upon learning. It was postulated that taking reading out of the formal learning environment might impact upon students’ willingness to engage with the literature, and confidence in doing so. A staff-student research partnership initiative funded by Kingston University allowed this hypothesis to be tested. Three Tea Club sessions, informal drop-in reading sessions were offered in a student-owned space within the Students’ Union. Refreshments were supplied, aiming for a ‘coffee house’ feel. Although the numbers of students who engaged with the Tea Club were small, evaluations were positive. In particular students valued the opportunity for peer learning. However the chosen environment was too noisy. Future sessions will be offered within a different, less noisy environment with facilities for refreshments, and will be offered throughout the academic year to facilitate student engagement.Keywords: Learning environment, peer support, extracurricular, scientific readin

A Suspended Array of Square Patch Metamaterial Absorbers for Terahertz Applications

A suspended array of square metallic patches on a thin dielectric layer is introduced as a terahertz absorber. The absorber is fabricated on a metalized substrate and the device exhibits metamaterial behavior at specific frequencies determined by the size of the patches. It is feasible to place patches with different sizes in an array formation for a broadband absorber. Design of the absorber is described using electromagnetic simulations. The absorber structure was fabricated on a silicon wafer and its characteristics were measured using a terahertz time domain spectroscope. The measured data match well the simulations indicating strong absorption peaks in a band of 0.5-2 THz
