The genetic variability of whitefly (Bemisia tabaci) species, the vectors of cassava mosaic begomoviruses (CMBs) in cassava growing areas of Kenya, Tanzania, and Uganda, was investigated through comparison of partial sequences of the mitochondria cytochrome oxidase I (mtCOI) DNA in 2010/11. Two distinct species were obtained including sub-Saharan Africa 1 (SSA1), comprising of two sub-clades (I...

The luminescent complex [(ThiaSO2)2(MnII)4F]− (ThiaSO2 = p-tert-butylsulfonylcalixarene) was introduced between layered double hydroxides. material displays a very high sensitivity to its luminescence emission with oxygen.

Background and objectives:Alzheimer’s disease (AD) is a neurodegenerative disorder. Nowadays, many investigations are performed to find new drugs for AD and medicinal plants are considered as one of the most important sources for developing new drugs. According to the role of oxidant agents and acetylcholinesterase enzyme (AChE) in AD, plants with antioxidant and AChE inhibitio...

Genetic recombination is considered to be a very frequent phenomenon among enteroviruses (Family Picornaviridae, Genus Enterovirus). However, the recombination patterns may differ between enterovirus species and between types within species. Enterovirus C (EV-C) species contains 21 types. In the capsid coding P1 region, the types of EV-C species cluster further into three sub-groups (designated...

Silicon nanowire field effect transistors (SiNW-FETs) have shown great promise as biosensors in highly sensitive, selective, real-time and label-free measurements. While applications of SiNW-FETs for detection of biological species have been described in several publications, less attention has been devoted to summarize the conjugating methods involved in linking organic bio-receptors with the ...

Freshwater denitrification removes a considerable amount of nitrogen from inland waters, which are under pressure eutrophication and warming. However, incomplete can lead to the formation N2O, potent greenhouse gas, amplify climatic Although temperature effects on well studied in individual habitats experiments, global patterns temperature-responses N2O emissions remain be elucidated. Here, we ...

For noncontact optical thermometry, in contrast with fluorescence intensity ratio (FIR) technology, excitation (EIR) technology has been seriously limited due to low sensitivity. Moreover, by exploring all possible temperature-dependent response, developing multimode thermometry is of great importance. In this work, a new Na2Y2TeB2O10 (NYTB):Tb3+...

We study a scalar dark matter (DM) model with two DM species coupled to the Standard Model (SM) particles via sub-GeV photon. In this model, we find that conversion occurs through photon and it plays fundamental role in setting observed relic abundance. Furthermore, candidates can be produced at fixed-target experiments la Beam- Dump. Detailed predictions for signal backgrounds are obtained hel...
