Thousands of plant species rely on ants to disperse their seeds, including many South American epiphytes and vines, which, apart from minimizing competition among seedlings, may also reduce competition among different plant species (Handel & Beattie, 1990). The lianas of the Genus Strychnos (Loganiaceae) are recognized as having fruits with highly poisonous seeds containing strychnine in the in...
Abstract The loss of large frugivores leads to seed dispersal and regeneration failure numerous large-seeded trees near mother trees. Although Janzen–Connell effects are considered as the primary underlying cause, other factors remain understudied. Here, we used a field experiment test impact flesh persistence on recruitment two Sapotaceae species that lost their dispersers. In rainforest Mare ...
BACKGROUND Cleaning of environmental surfaces in hospitals is important for the control of methicillin-resistant Staphylococcus aureus (MRSA) and other hospital-acquired infections transmitted by the contact route. Guidance regarding the best approaches for cleaning, however, is limited. METHODS In this study, a mathematical model based on ordinary differential equations was constructed to st...
Selecting suitable cleaning agents and determining justifiable cleaning process parameters are critical prerequisites for cleaning validation. Proper selection of these cleaning agents and parameters could simplify cleaning validation efforts immensely. Process cleaners may range from a single component, such as an organic solvent, to multicomponent formulations that use multiple cleaning mecha...
In the last decade, there have been significant developments into integration of robots and automation tools with brachytherapy delivery systems. These systems aim to improve the current paradigm by executing higher precision and accuracy in seed placement, improving calculation of optimal seed locations, minimizing surgical trauma, and reducing radiation exposure to medical staff. Most of the ...
The waste associated with cleaning of process equipment is probably a significant contr ibutor to the total waste volume generated by industry. This paper addresses the following aspects related to equipment cleaning waste generation: o Review of reasons for cleaning process equipment o Reduction of cleaning frequency o Reduction of quantity and toxicity of cleaning waste o Costs associated wit...
A UHV atomic hydrogen-cracking cell has been constructed to produce atomic hydrogen in order to perform in-situ cleaning of semiconductor samples. The cell was calibrated and tested with the objective of cleaning the III-V semiconductor samples such as GaAs. Mass spectroscopy studies during the atomic hydrogen cleaning of the GaAs samples revealed the chemical process of the hydrogen cleaning. ...
Soap as a cleaning product has been the primary needs since spread of Covid-19. Government regulations require people to wash their hands. Hence demand for soap production is increasing. This study aimed obtain Traveling Paper formulation from VCO and durian seeds antibacterial activity on skin. The experimental laboratory method uses quantitative qualitative descriptive analysis. treatment in ...
