Accurate identification of promoter regions and transcription start sites (TSS) in genomic DNA allows for a more complete understanding of the structure of genes and gene regulation within a given genome. Many recently published methods have achieved high identification accuracy of TSS. However, models providing more accurate modeling of promoters and TSS are needed. A novel identification meth...

During transcription initiation, RNA polymerase (RNAP) binds to promoter DNA, unwinds promoter DNA to form an RNAP-promoter open complex (RPo) containing a single-stranded 'transcription bubble,' and selects a transcription start site (TSS). TSS selection occurs at different positions within the promoter region, depending on promoter sequence and initiating-substrate concentration. Variability ...

Chitosan interact with polyphosphate ions to form nanoparticles with different diameters depending on the mutual ratio among them. Three nanoparticles have been prepared and were characterized by spectral and X-ray diffraction tools. TEM analysis revealed there diameters. The nanoparticles were thoroughly studied for wastewater treatment such as the removal of Total Suspended Solid (TSS), Bioch...

The preservation of water resources in modern urbanized society is a major concern. In this study, floating constructed wetland (FWT) pilot plant was designed and for the treatment polluted wastewater drain. A series experiments were run continuously year pilot-scale FWTs semi-arid area located Egypt’s Delta. Four aquatic species (Eichhornia, Ceratophyllum, Pistia stratiotes, Nymphaea lotus) us...

In the wastewater treatment process, floatation unit have been developed to remove particles or flocs that tend be difficult settle, such as fat oil and grease (FOG) total suspended solids (TSS). Flotation is a operation can separate liquid phase solid from phase, this occur due presence of saturated air which mixed so it contains fine bubbles help separated. This research was conducted by trea...

In this study, landfill leachate treatment by coagulation and optimization of process parameters were aimed. Alum (Al2(SO4)3) Poly Aluminum Chloride (PACl) used as coagulants to remove total suspended solids (TSS) from leachate, coagulant dose, reaction time, pH optimized variables. The Box-Behnken, one the response surface methodology designs, was in modeling process. R2 values very high (&amp...

SatC is a noncoding subviral RNA associated with Turnip crinkle virus (TCV). A 100-nt stretch in the 3' UTR of TCV contains three hairpins and two pseudoknots that fold into a tRNA-shaped structure (TSS) that binds 80S ribosomes. The 3' half of satC is derived from TCV and contains 6-nt differences in the TSS-analogous region. SatC binds poorly to 80S ribosomes, and molecular modeling that pred...

The aim of this study was to examine the effect of toki-shakuyaku-san (TSS) on mild cognitive impairment (MCI) and Alzheimer's disease (AD) using single-photon emission computed tomography (SPECT). All subjects were administered TSS (7.5 g/day) for eight weeks. SPECT and evaluations using the Mini Mental State Examination (MMSE), Neuropsychiatric Inventory, and Physical Self-Maintenance Scale w...

The paper investigates the dynamic behaviour of Inverse Fluidized Bed (IFB) for treatment petroleum wastewater using adsorbents date seed activated carbon (DSAC) and commercial coconut shell (CCAC). fluidization is downward flow technique, where density particles are less compared to liquid density. IFB wasexperimentally validated by analysing chemical oxygen demand (COD) removalefficiency, tot...

The paper presents a study of a pilot plant treating light greywater for seven flats. The pilot plant combines biological treatment (RBC) with physicochemical treatment (sand filtration and disinfection). The pilot plant produced effluent of excellent quality, meeting the urban reuse quality regulations, and was very efficient in TSS turbidity and BOD removal: 82%, 98% and 96%, respectively. CO...
