Análisis de sustratos aceptados para la co-digestión anaeróbica en la PTAR de Straubing, Alemania

Revista EIA
La adopción de nuevas formas de producción energética es uno de los retos que enfrentan los países a nivel mundial debido al progresivo agotamiento de los combustibles fósiles. En ese sentido, la digestión conjunta de residuos orgánicos en Plantas de Tratamiento de Agua Residual (PTAR) ha ganado gran aceptación, pues ofrece una alternativa para usar ...

Detection and Extraction of Weak Pulse Signals in Chaotic Noise with PTAR and DLTAR Models

Mathematical Problems in Engineering, 2019
With the development in communications, the weak pulse signal is submerged in chaotic noise, which is very common in seismic monitoring and detection of ocean clutter targets, and is very difficult to detect and extract. Based on the threshold autoregressive model, pulse linear form, Markov chain Monte Carlo (MCMC), and profile least squares (PrLS ...

CARACTERIZACIÓN FISICOQUÍMICA Y MICROBIOLÓGICA DE LODOS DE PTAR Y BES BAJO UN ENFOQUE DE REAPROVECHAMIENTO AGRONÓMICO

Ecología Aplicada
The objective of the study was to evaluate the agronomic potential of WWTP and DT sludge produced in Peru. For this, different aerobic and anaerobic wastewater treatment technologies were selected, as well as on-site sanitation systems in the cities of Lima, Ayacucho, Arequipa and Cusco.

Long non-coding RNA PTAR inhibits apoptosis but promotes proliferation, invasion and migration of cervical cancer cells by binding miR-101. [PDF]

Bioengineered, 2021
In this study, the expression of PTAR in cervical cancer tissues and cells was quantified by real-time PCR. Then, the roles of PTAR in HeLa cell proliferation and cell cycle were analyzed by a CCK-8 assay and flow cytometry, respectively.The effects of ...

Characterization of the replication and stability regions of Agrobacterium tumefaciens plasmid pTAR [PDF]

Journal of Bacteriology, 1984
A 5.4-kilobase region containing the origin of replication and stability maintenance of the 44-kilobase Agrobacterium tumefaciens plasmid pTAR has been mapped and characterized. Within this region is a 1.3-kilobase segment that is capable of directing autonomous replication.

The suppression of a selfish genetic element increases a male's mating success in a fly

Ecology and Evolution, Volume 13, Issue 11, November 2023., 2023
We investigated the mating ability of SR, suppressed SR, and wild‐type males. We found that males that carried a suppressor against SR had higher mating success. We also found that SR suffered a fitness cost in terms of reduced offspring production. Abstract X chromosome meiotic drive (XCMD) kills Y‐bearing sperm during spermatogenesis, leading to the ...

Dynamic metagenome‐scale metabolic modeling of a yogurt bacterial community

Biotechnology and Bioengineering, Volume 120, Issue 8, Page 2186-2198, August 2023., 2023
Abstract Genome‐scale metabolic models and flux balance analysis (FBA) have been extensively used for modeling and designing bacterial fermentation. However, FBA‐based metabolic models that accurately simulate the dynamics of coculture are still rare, especially for lactic acid bacteria used in yogurt fermentation. To investigate metabolic interactions
