A simple and economical procedure for the attachment of reducing sugars to aminated solid supports has been developed. Reaction of the amino groups on the solid support with p-nitrophenyl chloroformate, followed by 1,6-hexanediamine, yields a chain-extended amine to which reducing sugars can be attached while remaining accessible to macromolecules. Immobilization of the reducing sugars involves a

The two thio analogues (2 and 3) of TMSEt galabioside [2-(trimethylsilyl) ethyl 4-O-(α-D-galactopyranosyl)-β-D-galactopyranoside, 1], having anomeric sulfur instead of anomeric oxygen atoms, were synthesized and their conformations investigated by NMR and computational (MM3) methods. A spacer galabioside was covalently coupled to aminated microtiter plates, and binding of a bacterial pilus adhesin

For a better understanding of the effects of regional groundwater management for different land-use types on nitrogen content in groundwater, we investigated the Miyakonojo River Basin in south of Japan where the Nitrate Directive Plan has been in practice since 2004. For this purpose, we used nitrogen concentrations from 420 wells between 2000 and 2017 together with 8 different land-use categoriz

Momentary contentment theory is a grounded theory explaining how to find safety and balance in life despite an awareness of life´s unpredictability. The theory is based on communion with others, proactivity and acceptance. It explains cognitive and emotional ways of finding a sense of safety and enjoyment despite illness and accidents. Three concepts are central to Momentary contentment theory: do

After emerging in China in late 2019, the novel Severe acute respiratory syndrome-like coronavirus 2 (SARS-CoV-2) spread worldwide and as of early 2021, continues to significantly impact most countries. Only a small number of coronaviruses are known to infect humans, and only two are associated with the severe outcomes associated with SARS-CoV-2: Severe acute respiratory syndrome-related coronavir

Growth approaches that limit the interface area between layers to nanoscale regions are emerging as a promising pathway to limit the interface defect formation due to mismatching lattice parameters or thermal expansion coefficient. Interfacial defect mitigation is of great interest in photovoltaics as it opens up more material combinations for use in devices. Herein, an overview of the vapor-liqui

This article examines the outcome of the International Law Commission’s (ILC) Study on the Protection of the Environment in relation to Armed Conflict as adopted on first reading. The twenty-eight draft principles, adopted by the ILC in July 2019, aim to enhance environmental protection before, during, and after armed conflict. This article evaluates the strengths and weaknesses of the draft princ

We study exclusive production of scalar χc0χc(0++) and pseudoscalar ηc charmonia states in proton-proton collisions at the LHC energies. The amplitudes for gg→χc0 as well as for gg→ηc mechanisms are derived in the kT-factorization approach. The pp→ppηc reaction is discussed for the first time. We have calculated rapidity, transverse momentum distributions, and such correlation observables as the d

The promotion of locally produced food has been a growing marketing trend in recent years. Locally produced food is associated with positive values such as environmental benefits, fresher and safer products as well as contributing to building closer ties between people in local communities. We use a case study were a local fish auction was established in the Stockholm area in Sweden with the aim t

The first case of COVID-19 was identified in Libya on 24/3/2020, and about 2 months later, the number of reported COVID-19 cases started to increase notably. The outbreak was first prominent in the southern region (Sabha) and then spread to the western and eastern parts of Libya. By 24/12/2020, the reported total number of deaths from COVID-19 reached 1415. There seems to be no published data on t
