Abstract:

This paper focuses on computational fluid dynamics (CFD) simulation of the dynamic exploited influence of wind field in the open pit quarry. We have picked up 3 normal exploitation parameters, e.g. the exploited depth z, the type of small hills and the measured velocity u1, 7 simulated experiments have been done by software Fluent as well. In our experiments, the features of velocity field around the mine are shown, with the effects of open pit quarry, so as to analyze the changes of wind speed when it gets through this mine. To be exact, it will be possible to deduce there is negative correla

Abstract:

Organic farming is a good way to reduce environmental pollution. However, no related detection of fertilizer applications, which are extremely important in organic farming, exists. The δ15N value of chemical fertilizer (–3.8 to +2‰) is far lower than compost (>+10‰). Thus, natural 15N abundance (δ15N) in leaves and fruits may be used to reveal the application of N fertilizer. In this experiment, six treatments were laid out: 635 g (C1), 952 g (C2), and 1270 g (C3) of compost were applied as basal fertilizer in each pot. Alternately, 10.7 g (U1), 16 g (U2), and 21.3 g (U3) of urea were appli

This paper concerns control BVPs, driven by ODEs x′t=ut, using controls u0· &u1· in L1a,b,R2. We ask these two controls to satisfy a very simple restriction: at points where their first coordinates coincide, also their second coordinates must coincide; which allows one to write (u1−u0)·=v·1,f· for some f·. Given a relaxed non bang-bang solution x¯·∈W1,1a,b,R2, a question relevant to applications was first posed three decades ago by A.

AbstractStimulated cells and cancer cells have widespread shortening of mRNA 3’-untranslated regions (3’UTRs) and switches to shorter mRNA isoforms due to usage of more proximal polyadenylation signals (PASs) in introns and last exons. U1 snRNP (U1), vertebrates’ most abundant non-coding (spliceosomal) small nuclear RNA, silences proximal PASs and its inhibition with antisense morpholino oligonucleotides (U1 AMO) triggers widespread premature transcription termination and mRNA shortening. Here we show that low U1 AMO doses increase cancer cells’ migration and invasion in vitro by up to 500%, w

Abstract:

The essential role of U4 snRNP in pre-messenger RNA (mRNA) splicing has been well established. In this study, we utilized an antisense morpholino oligonucleotide (AMO) specifically targeting U4 snRNA to achieve functional knockdown of U4 snRNP in HeLa cells. Our results showed that this knockdown resulted in global intronic premature cleavage and polyadenylation (PCPA) events, comparable to the effects observed with U1 AMO treatment, as demonstrated by mRNA 3′-seq analysis. Furthermore, our study suggested that this may be a common phenomenon in both human and mouse cell lines. Additionally, w

Of significant interest, U1‐70K has been implicated in Alzheimer's disease, in which it tends to form detergent‐insoluble aggregates.
