The incidence of failure of embedded pipelines has increased in Korea due to the increasing applied load and the improper compaction of bedding and backfill materials. To overcome these problems, a prefabricated lightweight plastic foundation using recycled plastic was developed for sewer pipelines. A small scale laboratory chamber test and two field tests were conducted to verify its construct...

We used a next-generation, Illumina-based sequencing approach to characterize the bacterial community development of apple rhizosphere soil in a replant site (RePlant) and a new planting site (NewPlant) in Beijing. Dwarfing apple nurseries of 'Fuji'/SH6/Pingyitiancha trees were planted in the spring of 2013. Before planting, soil from the apple rhizosphere of the replant site (ReSoil) and from ...

Dendritic protein synthesis plays a critical role in several forms of synaptic plasticity, including BDNF (brain-derived neurotrophic factor)-mediated long-term synaptic potentiation (LTP). Dendritic transcripts are typically transported in a repressed state as components of large ribonucleoprotein complexes, and then translated upon stimulation at, or in the vicinity, of activated synapses. He...

The study was conducted in January 2020 at the Indragiri Tembilahan Islamic University experimental garden, aimed to find out influence of combination alluvial soil and peat as a planting medium on growth production onions (Allium ascollanicum L), best for (Alluium ascalonicum L). research design used is non-factorial randomized group (RAK) design, consisting 7 treatments 3 repeats. A0 = Peat S...

In this study, we investigated the effects of organic waste and moisture superabsorbent on the amount of available water and delay in moisture equivalent of permanent wilting point (PWP) in soil. In the first phase (soil incubation phase), 12 treatments were studied in a completely randomized design at the Soil Science Laboratory of Science and Research Branch, Tehran. The treatments c...

Here we have used siRNAs and time-lapse epifluorescence microscopy to examine the roles of various candidate mitotic cyclins in chromatin condensation in HeLa cells. Knocking down cyclin A2 resulted in a substantial (∼7 h) delay in chromatin condensation and histone H3 phosphorylation, and expressing an siRNA-resistant form of cyclin A2 partially rescued chromatin condensation. There was no det...

Compounds AT2433-A1 (A1), AT2433-A2 (A2), AT2433-B1 (B1), and AT2433-B2 (B2) were isolated from the cultured broth of Actinomadura melliaura sp. nov. (SCC 1655). Structurally these materials are closely related to rebeccamycin (1), an indolocarbazole antitumor antibiotic. A1, A2, B1, and B2 were active against Staphylococcus aureus A9537, Streptococcus faecalis A20688, Streptococcus faecium (AT...

We are going to discuss in brief and without proof the equality case in Theorem 1.1. Before we can do this, we need to establish a notation: The notation (a1; a2; :::; an) (b1; b2; :::; bn) is going to mean that for every two numbers i and j from the set f1; 2; :::; ng ; we have aibj = biaj: Note that if all numbers b1; b2; :::; bn are nonzero, then (a1; a2; :::; an) (b1; b2; :::; bn) is equiva...
