The onion (Allium cepa L.) is widely planted worldwide as a valuable vegetable crop. The scales of an onion bulb are a modified type of leaf. The one-layer-cell epidermis of onion scales is commonly used as a model experimental material in botany and molecular biology. The lower epidermis (LE) and upper epidermis (UE) of onion scales display obvious differences in microscopic structure, cell di...

Abstract Dayak onion is an herbal plant from Kalimantan Island, Indonesia, with functional properties commonly used for various diseases such as cholesterol, diabetes, stroke, etc. This study aims to determine the quality of Da yak onions before and after making flour so that it can be a guide when processed, mixed, or fortified into other food ingredients. Processing begins proximate testing f...

Human intestinal tissue samples are barely accessible to study potential health benefits of nutritional compounds. Numbers of animals used in animal trials, however, need to be minimalized. Therefore, we explored the applicability of in vitro (human Caco-2 cells) and ex vivo intestine models (rat precision cut intestine slices and the pig in-situ small intestinal segment perfusion (SISP) techni...

New ways of working have to be explored to ensure learning and knowledge become prime foci in the Knowledge Economy. One approach would be to re-engineer conventional processes to centre on knowledge rather than on tangible deliverables and their production activities. This paper demonstrates that strategy, by proposing radical new theories of projects and project management. Project management...

Management of onion thrips continues to be a high pest priority for Wisconsin onion growers. In 2006 the hot and dry conditions experienced in mid-summer led to increased populations that were very difficult to control in some areas. Furthermore, many of the earlier registered products for control of onion thrips are loosing control efficacy. Onion thrips insensitivity to λ -cyhalothrin (Warrio...

Aqueous based controlled decoration of platinum nanoparticles on plasma treated carbon nano-onions (CNOs) occurs within the shear flow generated by a vortex fluidic device (VFD), using ascorbic acid as the reducing agent, with the electrocatalytic potential of the resulting Pt-NPs@CNOs nano-composites demonstrated.

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a well-known onion pest worldwide. Onion thrips cause both direct and indirect damage to onion by feeding and ovipositing on leaves that may cause green onions (scallions) to be unmarketable and dry bulb onion size to be reduced. Onion thrips can also transmit several plant pathogens that reduce onion bulb size and quality. One ...

The Internet has played a major role in the distribution of New Psychoactive Substances (NPS), and crypto markets are increasingly used for the anonymous sale of drugs, including NPS. This study explores the availability of individual NPS and vendors on the crypto markets and considers whether crypto markets are a reliable platform for the sale of NPS. Data was collected from 22 crypto markets ...

Correction for ‘Carbon nano-onions from waste oil application in energy storage devices’ by SungHoon Jung et al. , New J. Chem. 2020, 44 7369–7375, https://doi.org/10.1039/D0NJ00699H.

The preparation of novel NIR fluorescent carbon based nanomaterials, consisting of boron difluoride azadipyrromethene fluorophores covalently attached to carbon nano-onions, is demonstrated. In addition, the analysis of the new nanomaterial is presented. The fluorescent nano-derivative properties are customized such that their emission can be reversibly on/off modulated in response to pH, which...
