  • Shedding Light on Land Tenure in Africa

    Land and natural resources lie at the heart of social, political, and economic life in much of rural Africa. They represent fundamental assets—primary sources of livelihood, nutrition, income, wealth, and employment for African communities—and are a basis for security, status, social identity, and political relations. For many rural people, land and resources such as water, trees, and ...

  • Herb layer productivity under different light gaps in the forests of Western Ghats of Karnataka, India

    A productivity estimation of tree, shrub and herb layer biomass was undertaken in Uttara Kannada, a Western Ghats district in Karnataka in differentially managed forests. In addition to biomass, light gap in these sample sites was also estimated to understand the relationship between the light interception pattern at different canopy layers and their productivity. The studies indicate that tree ...

  • Morphological, anatomical, and physiological changes of orchardgrass leaves grown under fluctuating light regimes

    The physiological and anatomical adaptability of pastures growing under trees in silvopastoral systems can alter the efficiency of conversion of energy to dry matter (DM). This study was conducted to determine the effects of different fluctuating light regimes (from 24 to 100% transmissivity) on leaf physiology, morphology, anatomy, and structure of orchardgrass (Dactylis glomerata L.) in a ...

  • Impacts of altered light spectral quality on warm season turfgrass growth under greenhouse conditions

    Warm-season turfgrass quality declines under shade due to reduced photosynthesis, increased disease pressure, reduced carbohydrate production, tree root competition, and reduced lateral stem growth. Another factor limiting turfgrass growth and development under tree shade is variable qualities of light filtered by trees. However, effects of various filtered wavelengths on turfgrass performance ...

  • Characterization and activity of visible-light driven TiO2 photocatalyst doped with tungsten

    This research aimed to expand the activity of TiO2 down to the visible light region by modifying the sol-gel conditions and doping with tungsten. The optimum conditions for calcination temperature, acid type, and heating rate were 200°C, HNO3, and 1°C/min, respectively. The undoped TiO2 synthesized under these conditions could significantly absorb the visible light whereas ...

  • Light and moisture competition effects on biomass of red clover underseeded to winter wheat

    Red clover (Trifolium pratense L.) use as an underseeded cover crop in winter cereals has declined due to inability of growers to consistently establish uniform stands. The objective of this study was to assess the effect of light and soil moisture competition on underseeded red clover establishment and end of season dry matter production. Field trials were conducted at multiple locations in 2005 ...

  • New documentary shines a light on solutions to global species loss

    A paper published last week in the journal Science Advances claims the sixth major mass extinction is already underway ­— and this time humans are to blame. “We can confidently conclude that modern extinction rates are exceptionally high, that they are increasing, and that they suggest a mass ...

  • Corn morphology, mass, and grain yield as affected by early-season red: far-red light environments

    The spatial arrangement among plants affects both vegetative and reproductive meristem development. More axillary meristems develop at lower plant densities, which are associated with relatively high red:far-red light ratios (R:FRs; 645:735 nm). However, little is known about the effect of R:FR on corn (Zea mays L.) productivity. We conducted field research to determine the effect of early-season ...

  • Critical Operations Go Under Cover

    For a number of years, composting facilities have been using fabric structures to house finished compost screening, soil blending and product storage. They’ve also employed the structures to cover or fully enclose feedstock receiving and mixing. And some have gone as far as to put active composting operations inside fabric buildings. “More and more facilities are putting in fabric ...

  • Relationship between light and heavy fractions of organic matter for several agricultural soils in China

    Although numerous studies about the nature and turnover of soil organic matter (SOM) in light and heavy fractions (LFOM and HFOM, respectively) have been made, little information is available in relation to the relationship between LFOM and HFOM, and no attempts have been made to quantify a general relationship between LFOM and HFOM for agricultural soils under field condition. Our hypothesis is ...

  • The photodynamic inactivation of Staphylococcus aureus in water using visible light with a new expanded porphyrin

    In this work, the results of the application of organic expanded porphyrins in the disinfection of water by the photodynamic inactivation (PDI) technique are presented. The photoinactivation properties of a novel, expanded porphyrin, namely 20-(4-carboxyphenyl)-2,13-dimethyl-3,12-diethyl-(22π) pentaphyrin (PCCox), were tested in the disinfection of water using Staphylococcus ...

  • Coordination of a supply chain with a loss-averse retailer under two types of contracts

    This article studies a one-manufacturer and -retailer supply chain facing uncertain demand. The manufacturer sells a perishable product to the retailer. Different from the traditional supply chain models based on risk neutrality, this article takes the viewpoint of the behavioural theory and assumes that the retailer is loss averse. The objective is to design the supply contract that provides a ...

  • Degradation of abamectin and doramectin in sheep faeces under different experimental conditions

    Avermectins is the collective name given to a range of animal health products used in the prevention of parasitosis. Residues of these drugs retain their insecticidal properties after excretion in livestock faeces. We investigated the degradation of abamectin and doramectin in sheep faeces under the laboratory and field conditions. In the first two, out of three experiments, we exposed collective ...
