The behaviour of a non-spherical osmotic motor an axisymmetric catalytic particle self-propelling in a dilute dispersion of reactant particles is considered. In concrast to a conventional osmotic motor that creates differences in concentration, and hence in osmotic pressure, due to asymmetry in reaction rate along its surface (e.g. a Janus particle with reactive and non-reactive patches), a non...

Lepidopteran insects use sex pheromones to communicate for mating. Olfactory communication and mate-finding can be prevented by permeating the atmosphere with synthetic pheromone. Pheromone-mediated mating disruption has become a commercially viable pest management technique and is used to control the codling moth, Cydia pomonella, a key insect pest of apple, on 160,000 ha worldwide. The codlin...

Since 2004, the Republic of Iraq has undertaken a concerted effort to comply with all of its international obligations to prevent the proliferation and the use of chemical, biological, radiological, and nuclear (CBRN) weapons. A centerpiece of this effort is Iraq's development of a National Biorisk Management System. The Iraqi National Monitoring Authority (INMA), which is responsible for CBRN ...

Food security in the East African Highlands is dependent upon the productivity of lands managed by smallholders who face difficult challenges in maintaining the fertility of their soils. A study was conducted to identify indicators of soil fertility status that are consistent with farmers’ perceptions of soil fertility. Physical, chemical and biological properties of soils were measured from pa...

The excessive consumption of herbicides has gradually led to the herbicide resistance weed phenomenon. Managing weeds can only be explicated by applying high-tech strategies such as artificial intelligence (AI)-based methods. We review here AI-based methods and tools against herbicide-resistant weeds. There are a few commercially available technologies for controlling weed, machine learning mak...

Diagnostic imaging is a valuable device in clinical management of poisoned patients presenting to emergency units in a comatose state. Some toxic agents have adverse effects on the central nervous system (CNS). Non-contrast computed tomography (CT) of the brain, as an available diagnostic method with a high resolution, can provide useful information about structural disturbances of unconscious ...

Psychological trauma may result in depression. Veterans are particularly prone to development of depression. 100 male veterans (39 injured by chemical and 61 by non-chemical warfare) with 30% to 70% of physical disability were compared with 100 age- and sex-matched individuals selected from general population serving as comparison group. The diagnosis of depression was made according to the DSM...

There is growing public concern about pesticides’ non-target effects on humans and other organisms, and many pests have evolved resistance to some of the most commonly-used pesticides. Together, these factors have led to increasing interest in non-chemical, ecologicallysound ways to manage pests [1]. One pest-management alternative is the diversification of agricultural fields by establishing “...
