Climate change has resulted in increased vulnerability of smallholder farmers in marginal areas of Zimbabwe where there is limited capacity to adapt to changing climate. One approach that has been used to adapt to changing climate is in-field water harvesting for improved crop yields in the semi- arid regions of Zimbabwe. This review analyses the history of soil and water conservation in Zimbab...

In this paper, a new configuration of Tapered Slot Antenna (TSA) with improved radiation pattern is proposed and studied. This antenna is designed in the form of a substrate integrated waveguide (SIW) array with respect to side lobe level constraints. For side lobe reduction, a simple quasi-triangular distribution is proposed and is accomplished uniquely by means of 3 dB power dividers. A 12-wa...

For stormwater harvesting to achieve its full potential in mitigating water scarcity problems and restoring stream health, it is necessary to evaluate the human and environmental health risks and benefits associated with it. Stormwater harbors large amounts of pollutants and has traditionally been viewed as a leading cause of water-quality degradation of receivingwaters. Harvesting stormwater f...

Agricultural intensification in America has replaced native warm-season grasses (NWSG) with introduced forages causing wildlife habitat loss and population declines for the northern bobwhite (Colinus virginianus) and similar ground-nesting birds. Reintroducing NWSGs onto managed grasslands to reverse grassland bird population declines lacks information about appropriate multi-purpose management...

There are numerous active and abandoned waste sites in the US and worldwide. Post‐closure development of these sites is desirable from an environmental, societal and economical perspective. However, the post‐closure development of landfills presents many challenges. A major challenge is the generally soft nature of the municipal solid waste (MSW) and the high pote...

The object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. The evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. The results revealed that the effect of soil moisture content was only significant on...

The diversion and recovery of organic waste are one the most significant opportunities challenges for reducing environmental impacts disposal internationally, as recognised by United Nations’ SDG 12 that seeks to “ensure sustainable consumption production patterns”. This issue is particularly pertinent developed countries, like Australia, who have a high propensity removal arising from their in...

introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

Biocatalysis can enable a closed-loop recycling of post-consumer PET waste.

This study aimed to evaluate the effect of system-acquired resistance inducing compounds applied during pre-harvest ‘Navelina’ orange and ‘Ortanique’ tangor in controlling post-harvest disease caused by Penicillium digitatum. The products were acibenzolar-s-methyl (ASM), imidacloprid (IMI), methyl jasmonate (MeJa), sodium selenite, potassium silicate, thiamethoxam (TMT). Sterile distilled water...
