Abstract. Brown carbon (BrC) contributes significantly to aerosol light absorption and
thus can affect the Earth's radiation balance and atmospheric photochemical
processes. In this study, we examined the light absorption properties and
molecular compositions of water-soluble (WS-BrC) and water-insoluble
(WI-BrC) BrC in PM2.5 collected from a rural site in the Guanzhong
Basin – a highly polluted region in northwest China. Both WS-BrC and WI-BrC
showed elevated light absorption coefficients (Abs) in winter (4–7 times those in summer) mainly attributed to enhanced emissions from residential
biomass burning (BB) for heating of homes. While the average mass absorption
coefficients (MACs) at 365 nm (MAC365) of WS-BrC were similar between daytime
and nighttime in summer (0.99±0.17 and 1.01±0.18 m2 g−1, respectively), the average MAC365 of WI-BrC was more than a
factor of 2 higher during daytime (2.45±1.14 m2 g−1)
than at night (1.18±0.36 m2 g−1). This difference was
partly attributed to enhanced photochemical formation of WI-BrC species,
such as oxygenated polycyclic aromatic hydrocarbons (OPAHs). In contrast,
the MACs of WS-BrC and WI-BrC were generally similar in winter and both
showed few diel differences. The Abs of wintertime WS-BrC correlated
strongly with relative humidity, sulfate and NO2, suggesting that
aqueous-phase reaction is an important pathway for secondary BrC formation
during the winter season in northwest China. Nitrophenols on average
contributed 2.44±1.78 % of the Abs of WS-BrC in winter but only
0.12±0.03 % in summer due to faster photodegradation reactions.
WS-BrC and WI-BrC were estimated to account for 0.83±0.23 % and
0.53±0.33 %, respectively, of the total down-welling solar
radiation in the ultraviolet (UV) range in summer, and 1.67±0.72 % and
2.07±1.24 %, respectively, in winter. The total absorption by BrC
in the UV region was about 55 %–79 % relative to the elemental carbon (EC)
absorption.
Early-to-mid Miocene erosion rates inferred from pre-Dead Sea rift Hazeva River fluvial chert pebbles using cosmogenic 21Ne
Authors: Ben-Israel Michal , Matmon Ari , Hidy Alan J. , Avni Yoav , Balco Greg 
Published: April 2020

Abstract. In this work, we utilize a novel application of cosmogenic 21Ne measurements in chert to compare exposure times measured in eroding surfaces in the central Jordanian Plateau with exposure times from chert pebbles transported by the Miocene Hazeva River. The Miocene Hazeva River was a large fluvial system (estimated catchment size > 100 000 km2) that drained the Arabian Plateau and Sinai Peninsula into the Mediterranean Sea during the early-to-mid Miocene. It was established after the rifting of the Red Sea uplifted the Arabian Plateau during the Oligocene. Following late-Miocene-to-early-Pliocene subsidence along the Dead Sea rift, the Hazeva drainage system was abandoned and dissected, resulting in new drainage divides on either side of the rift. We find modern erosion rates derived from cosmogenic 21Ne, 26Al, and 10Be in exposed in situ chert nodules to be extremely slow (between 2–4 mm kyr−1). Comparison between modern and paleo-erosion rates, measured in chert pebbles, is not straightforward, as cosmogenic 21Ne was acquired partly during bedrock erosion and partly during transport of these pebbles in the Hazeva River. However, 21Ne exposure times calculated in Miocene cherts
are generally shorter (ranging between 0-0+59 and 242±113 kyr) compared to exposure times calculated in the currently eroding chert nodules presented here (269±49 and 378±76 kyr) and other chert
surfaces currently eroding in hyperarid environments. Miocene exposure times are shorter even when considering that they account for bedrock erosion in addition to maintained transport along this large river. Shorter exposure times in Miocene cherts correspond to faster paleo-erosion rates, which we attribute to a combination of continuous surface uplift and significantly wetter climatic conditions during the early-to-mid Miocene.
Adsorption to soils and biochemical characterization of commercial phytases
Authors: Caffaro María Marta , Balestrasse Karina Beatriz , Rubio Gerardo 
Published: April 2020

Abstract. Commercial phytases are widely used in poultry production, but
little is known about their potential use as biofertilizer for agricultural
crops as an alternative to reduce the use of synthetic fertilizers. Four
purified phytases isolated from Aspergillus niger and Escherichia coli were characterized biochemically and
in terms of their adsorption to soils belonging to the Mollisol order. Three
different organic P substrates were used to measure enzyme activity under a
wide range of pH (2.3 to 9) and temperatures (−10 to
70 ∘C) conditions: phytic acid, p-nitrophenyl-phosphate (pNP) and
glyceraldehyde-3-phosphate (G3Phosphate). Phytases had a low affinity for the
solid phase: 23 %–34 % of the added amount was adsorbed after 1 h of
incubation. Phytases from A. niger showed a higher capacity to release P (13 % on
average) than phytases from E. coli. All phytases were active throughout the pH and temperature ranges related to optimum crop production. At pH values commonly
found in agricultural soils (5.5–7), A. niger phytases released P with the following substrate ranking with respect to effectiveness: pNP > phytic acid > G3Phosphate. E. coli phytases, in comparison, released P following with the following substrate ranking with respect to effectiveness: pNP ∕ phytic
acid > G3Phosphate. The results obtained are promising in terms of
the use of phytases as a complement to P fertilization in agricultural
settings and encourage further studies under field conditions.

Authors: Nieva Silvia , Rodríguez Lidia , Roussel Solenn Roussel 
Published: April 2020

La atención clínica y educativa que se ofrece a niños bilingües es actualmente un reto para los profesionales. Es necesario investigar sobre la conceptualización
del bilingüismo, su naturaleza y su relación con los diferentes entornos de aprendizaje. El objetivo del presente trabajo es revisar la literatura científica con el fin de explorar el papel del entorno familiar y las competencias del fonoaudiólogo/logopeda para garantizar una intervención fonoaudiológica/logopédica funcional en población bilingüe. Para ello, se ha estudiado la información más representativa disponible sobre el enfoque naturalista de intervención en multilingüismo. Así, se pretende reflexionar sobre los modelos de intervención que mejor se adecúan a las necesidades específicas de los niños bilingües y el papel que puede adoptar la familia para contribuir al desarrollo comunicativo de los niños en contacto con varias lenguas.
En primer lugar, se ofrece una aclaración terminológica, así como una visión del marco naturalista de intervención. A continuación, se presentan la metodología y los resultados de la revisión efectuada para niños bilingües con diversidad funcional y alteraciones del lenguaje oral. Se incluyen también recomendaciones en relación a las competencias del fonoaudiólogo que trabaje con población bilingüe. Finalmente, se concluye con una propuesta de futuras líneas de
investigación aplicada en este campo considerando los modelos naturalistas centrados en la familia para proponer su adaptación a las intervenciones
realizadas con niños bilingües.

The Development and Implementation of a Novel Electronic Consult System by a Laboratory Medicine Service: Experience From the First 2 Years of Use
Authors: Stendahl Kristin , Siddon Alexa J. , Peaper David R. , Hauser Ronald G. , Campbell Sheldon , Tormey Christopher A. 
Published: April 2020

Context.—
A novel electronic consult (e-consult) system for a pathology and laboratory medicine service (PLMS) was implemented in 2015 at a high-complexity Veterans Administration health care facility. Consults were previously made through direct provider communication without documentation in the medical record.

Objective.—
To evaluate the utilization trends of the laboratory e-consult system at the Department of Veterans Affairs Connecticut facility during the first 2 years since inception.

Design.—
E-consultation involves pathology and laboratory medicine resident review followed by attending pathologist review and cosignature. E-consults to the pathology and laboratory medicine service from 2015 to 2017 were reviewed to record type of consult, requesting department, patient location, and turnaround time.

Results.—
The pathology and laboratory medicine service received 351 e-consults from 2015 to 2017. The volume varied by subsection: hematology and coagulation (215 of 351; 61%), chemistry (109 of 351; 31%), blood bank (19 of 351; 6%), and microbiology/virology (8 of 351; 2%). Hematology and coagulation consults were entirely for peripheral blood smear review (215 of 215; 100%). Chemistry consults were placed for toxicology/drugs of abuse (81 of 109; 74%), test utilization (17 of 109; 16%), or nontoxicology (11 of 109; 10%). Three services placed the majority of consults: primary care (279 of 351; 80%), hematology/oncology (39 of 351; 11%), and psychiatry (27 of 351; 8%). The median turnaround time for completion of e-consults was 1.2 days. Since e-consult implementation, the mean number of consults increased from 8.6/mo in 2015 to 18.1/mo in 2017, peaking in the last quarter of analysis in 2017 with a mean of 25.3 consults/mo.

Conclusions.—
This novel e-consult system improved accessibility to and documentation of answers to laboratory questions and increased the visibility of the pathology and laboratory medicine service. Future goals include development of outcomes-based measures to better assess the clinical impact of e-consults.
