Abstract:

In order to improve simulation precision of saturated hydraulic conductivity, use RETC and PTFs function to simulate saturated hydraulic conductivity by measured research area surface soil (0-20cm) physicochemical property and soil texture data. The simulation results were assessed by the approach of consisting in presenting a graphical representation of model simulated compared with observed values and by mean square error. The main results indicate that the RETC-PTFs and local PTFs mean square errors are 1.19 and 0.40 respectively. The precision of RETC-PTFs is lower than local PTFs function

Abstract:

RETC is a computer program that can be used to estimate soil hydraulic functions by easily determining soil properties. Using van Genuchten model in the RETC program gave high accuracy for estimating the hydraulic functions e.g., θ (h), k (θ) and D (h), also the mentioned program is considered a good tool for potential optimization of water management especially though calculating irrigation water after consuming 60% of the available water in root zone restoring technique. In the current study surface, soil samples (0 – 30 cm) from eight locations with a wide range in texture were collec

Abstract:

In response to the analysis of the functional status of forearm blood vessels, this paper fully considers the orientation of the vascular skeleton and the geometric characteristics of blood vessels and proposes a blood vessel width calculation algorithm based on the radius estimation of the tangent circle (RETC) in forearm near-infrared images. First, the initial infrared image obtained by the infrared camera is preprocessed by image cropping, contrast stretching, denoising, enhancement, and initial segmentation.

Abstract:

The soil water retention curve (SWRC) is essential for assessing water flow and solute transport in unsaturated media. The van Genuchten (VG) model is widely used to describe the SWRC; however, estimation of its effective hydraulic parameters is often prone to error, especially when data exist for only a limited range of matric potential. We developed a Metropolis-Hastings algorithm of the Markov chain Monte Carlo (MH-MCMC) approach using R to estimate VG parameters, which produces a numerical estimate of the joint posterior distribution of model parameters, including fully-quantified uncertai

Abstract The ability of simulation models to accurately predict water flow and solute transport in unsaturated soils usually depends on the accuracy of the parametric models used to describe the water retention curve θ(h) and unsaturated hydraulic conductivity Κ(θ). Experiments were conducted to determine θ(h) and Κ(θ) relationships of six different porous media. θ(h) relationships were determined using Haines-type assembly or Richards' pressure cell chambers, depending on the soil type. K(θ) relationships were determined using the one-step outflow method. RETC code was used to analyze hydraul

The stability of W–C compounds (WC)-type ReC has been controversial for many years.

Only P63/ mmc-Re2C, C2/ m-Re3C, P21/ m-Re4C, and C2/ m-Re5C2 phases are found to be stable under 0–300 GPa, while WC-type ReC has high enthalpy and does not appear in the phase diagram.

Abstract:

Abstract Uridine insertion/deletion editing of mitochondrial mRNAs is a characteristic feature of kinetoplastids, including Trypanosoma brucei. Editing is directed by trans-acting gRNAs and catalyzed by related RNA Editing Core Complexes (RECCs). The non-catalytic RNA Editing Substrate Binding Complex (RESC) coordinates interactions between RECC, gRNA and mRNA. RESC is a dynamic complex comprising GRBC (Guide RNA Binding Complex) and heterogeneous REMCs (RNA Editing Mediator Complexes). Here, we show that RESC10 is an essential, low abundance, RNA binding protein that exhibits RNase-sensitive

Abstract Urban dust is composed mostly of particles emitted by anthropogenic processes such as industry, vehicular, and maritime transport, so it may contain heavy metals and PM10 and PM2.5 particles, which affect human health, so its characterization should be taken into account in an environmental monitoring plan. Regarding UD, there are studies about heavy metal contamination conducted in Mexico City (CdMx) and the suburbs of the State of Mexico, but to date, there are none for the Tampico, Ciudad Madero, and Altamira.

ABSTRACT RNA uridylylation is critical for the expression of the mitochondrial genome in trypanosomes. Short U tails are added to guide RNAs and rRNAs, while long A/U heteropolymers mark 3′ ends of most mRNAs. Three divergent mitochondrial terminal uridylyl transferases (TUTases) are known: RET1 catalyzes guide RNA (gRNA) uridylylation, RET2 executes U insertion mRNA editing, and MEAT1 associates with the editosome-like complex. However, the activities responsible for 3′ uridylylation of rRNAs and mRNAs, and the roles of these modifications, are unclear. To dissect the functions of mitochondri

This study had the objective to evaluate the effect of irrigation and fertigation (NK) in the hydraulic conductivity and diffusivity of an Oxisol cultivated with sugarcane. The experimental design comprised randomized blocks in a 5 × 2 factorial scheme, with four replications. Treatments consisted of five levels of water replacement (100, 75, 50, 25 and 0%), with and without fertirrigation (NK). The planting of sugarcane, cultivar RB85-5453, was performed in a double row (W-shaped), 8 m long, with 1.80 m spacing between the double rows, the distance between the crops in the double row was 0.40

Abstract:

These studies illustrate the efficacy of a newly developed unsaturated/saturated flow apparatus (UFA) to decrease significantly the time required to obtain direct measurements of transport parameters. The UFA method can be applied to cores of soil, sediment, rock, concrete, or any other porous media, especially highly unsaturated and relatively impermeable materials. The UFA method is effective because it allows the operator to set variables in Darcy"s Law and impose any desired steady-state hydraulic conductivity. The UFA achieves hydraulic steady-state in hours by using an adjustable body fo

Abstract:

Kinetoplastid protists such as Trypanosoma brucei undergo an unusual process of mitochondrial uridine (U) insertion and deletion editing termed kinetoplastid RNA editing (kRNA editing). This extensive form of editing, which is mediated by guide RNAs (gRNAs), can involve the insertion of hundreds of Us and deletion of tens of Us to form a functional mitochondrial mRNA transcript. kRNA editing is catalyzed by the 20 S editosome/RECC. However, gRNA directed, processive editing requires the RNA editing substrate binding complex (RESC), which is comprised of 6 core proteins, RESC1-RESC6. To date th
