To prepare the efficiently flame retardants (FR) for the highly flammable polymers, the novel nitrogen-phosphorus based FRs (P-N FR) (PN-3, PN-4, PN-5, and PN-6) were prepared via phosphorus halides and amine derivatives with 40- 90 % in yields. The appearance of P-N FRs are lightly white solid. All P-N FRs are water-insoluble and show a melting point above 40oC. The success of the synthesis was confirmed by NMR analysis.

Whole-exome sequencing (WES) has become an efficient diagnostic test for patients with likely monogenic conditions such as rare idiopathic diseases or sudden unexplained death. Yet, many cases remain undiagnosed. Here, we report the added diagnostic yield achieved for 101 WES cases re-analyzed 1 to 7 years after initial analysis.

These reactions involved a condensation reaction of aromatic benzaldehydes, 5,5-dimethyl-1,3-cyclohexanedione, and dicyanomethane in a solvent mixture of ethanol and water, resulting in the desired products in moderate to good yields. The procedure is efficient and eco-friendly, and the products can be easily obtained by recrystallisation. Thus, this protocol offers an alternative to existing methods.

Ebook "Nutrient use efficiency in plants: Concepts and approaches" presents a broad overview of topics related to improvement of nutrient use efficiency of crops. Nutrient use efficiency (NUE) is a measure of how well plants use the available mineral nutrients. It can be defined as yield (biomass) per unit input (fertilizer, nutrient content). NUE is a complex trait: it depends on the ability to take up the nutrients from the soil, but also on transport, storage, mobilization, usage within the plant, and even on the environment.

This paper introduces a sentiment analysis approach based on a knowledge model to discover hidden affected objects, which combines ONtology and SentiMent technology, named ONSEM. In order to confirm the efficiency of the ONSEM framework, an experiment on a sentiment analysis dataset was developed and then yielded promising experimental results.

The results of resreach showed that rice areas were not distributed relatively uniform in all districts and the rice yield had average level when compared with the other rice cultivation areas. Rice yields in Thai Nguyen province sharply increased from 4.87 tons/ha (2010) to 5.49 tons/ha (2020) with the slightly decreasing the rice areas, it is proved that the farmer was not concerned to increase the planting areas while they focused on rising the yield potential and quality.

The heterogeneous recyclable catalyst, Cu-Fe hydrotalcite, was synthesized by coprecipitation, activated at 200oC and then successfully applied in Aldol reaction. This procedure also exhibited efficiency in the total synthesis of Abhexone, a flavor with high demand in the food and cosmetic industry.

Lolium perenne L. is the most important forage grass species in temperate regions. It is also considered as a sustainable source of biomass for energy production. However, improvement in biomass yield has been limited by comparison with other major crops. More efficient utilisation of genetic resources and improved breeding schemes are required to advance L. perenne breeding.

Nitrogen use efficiency is an important breeding trait that can be modified to improve the sustainability of many crop species used in agriculture. Rapeseed is a major oil crop with low nitrogen use efficiency, making its production highly dependent on nitrogen input.

Environmental radiation monitoring stations using the NaI(Tl) scintillation detector have higher sensitivity and provide more accurate radiation dose values than using Geiger-Muller counters. However, when the temperature of the environment changes, the measuring data changes (due to the temperature dependence on the NaI(Tl) light yield and the quantum efficiency of the PMT).

The cross-linked microbeads with average diameter of 106–300 μm, [poly(EGDMA-MATrp)], were obtained by copolymerization reaction of N-methacryloyl-L-(+)-tryptophan methyl ester (MATrp) with ethylene glycol dimethacrylate (EGDMA) and successfully applied as a heterogeneous catalyst in conjugate addition reaction of nitromethane to substituted 2-iminochromenes in aqueous media. A variety of 2-amino-4-(nitromethyl)-4H-chromene-3-carbonitriles has been synthesized in good yields. Polymeric microbeads were very durable and reused 5 times without a significant loss of activity.

Weed identification helps ensure crop yield and realize precision agriculture. Although the deep learning-based methods have achieved high performance, their needed large-scale annotated data is difficult to obtain, and the massive parameters lead to difficulties in model deployment in embedded applications. To develop efficient crop weeds classification system, we propose a dissimilarity-based method to select few but representative samples and consider data diversity.
