Published: February 2022

Abstract
A new, more comprehensive model of gas–grain chemistry in hot molecular cores is presented, in which nondiffusive reaction processes on dust-grain surfaces and in ice mantles are implemented alongside traditional diffusive surface/bulk-ice chemistry. We build on our nondiffusive treatments used for chemistry in cold sources, adopting a standard collapse/warm-up physical model for hot cores. A number of other new chemical model inputs and treatments are also explored in depth, culminating in a final model that demonstrates excellent agreement with gas-phase observational abundances for many molecules, including some (e.g., methoxymethanol) that could not be reproduced by conventional diffusive mechanisms. The observed ratios of structural isomers methyl formate, glycolaldehyde, and acetic acid are well reproduced by the models. The main temperature regimes in which various complex organic molecules (COMs) are formed are identified. Nondiffusive chemistry advances the production of many COMs to much earlier times and lower temperatures than in previous model implementations. Those species may form either as by-products of simple-ice production, or via early photochemistry within the ices while external UV photons can still penetrate. Cosmic ray-induced photochemistry is less important than in past models, although it affects some species strongly over long timescales. Another production regime occurs during the high-temperature desorption of solid water, whereby radicals trapped in the ice are released onto the grain/ice surface, where they rapidly react. Several recently proposed gas-phase COM-production mechanisms are also introduced, but they rarely dominate. New surface/ice reactions involving CH and CH2 are found to contribute substantially to the formation of certain COMs.
A New 3D Solar Wind Speed and Density Model Based on Interplanetary Scintillation
Authors: Porowski C. , Bzowski M. , Tokumaru M. 
Published: February 2022

Abstract
The solar wind (SW) is an outflow of the solar coronal plasma, which expands supersonically throughout the heliosphere. SW particles interact by charge exchange with interstellar neutral atoms; on the one hand, they modify the distribution of this gas in interplanetary space, and, on the other hand, they are the seed populations for heliospheric pickup ions and energetic neutral atoms (ENAs). The heliolatitudinal profiles of the SW’s speed and density evolve during the solar activity cycle. A model of the evolution of the SW’s speed and density is needed to interpret observations of ENAs, pickup ions, the heliospheric backscatter glow, etc. We derive the Warsaw Heliospheric Ionization Model 3DSW—WawHelIon 3DSW—based on interplanetary scintillation (IPS) tomography maps of the SW speed. We use the IPS tomography data from 1985 to 2020, compiled by Tokumaru et al. We derive a novel statistical method of filtering these data against outliers; we present a flexible analytic formula for the latitudinal profiles of the SW speed, based on Legendre polynomials of varying order with additional restraining conditions at the poles; fit this formula to the yearly filtered data; and calculate yearly SW density profiles using the latitudinally invariant SW energy flux observed in the ecliptic plane. Despite the application of a refined IPS data set, a more sophisticated data filtering method, and a more flexible analytic model, the present results mostly agree with those obtained previously, demonstrating the robustness of IPS studies of the SW’s structure.

Abstract
Ongoing large-scale optical time-domain surveys, such as the Zwicky Transient Facility (ZTF), are producing alerts at unprecedented rates. Analysis of transient sources has so far followed two distinct paths: archival analysis of data on transient sources at a time when they are no longer observable and real-time analysis at the time when the sources are first detected. The latter is the realm of alert brokers such as the Arizona-NOIRLab Temporal Analysis and Response to Events System (ANTARES). In this paper, we synthesize the two analysis paths and present a first systematic study of archival alert-broker data, focusing on extragalactic transients with multipeaked light curves identified in the ANTARES archive of ZTF alerts. Our analysis yields a sample of 37 such sources, including core-collapse supernovae (with two analogs of iPTF14hls), thermonuclear supernovae interacting with their surrounding circumstellar medium, tidal disruption events, luminous blue variables, and as yet unclassified objects. A large fraction of the identified sources is currently active, warranting allocation of follow-up resources in the immediate future to further constrain their nature and the physical processes at work.

C’est non le poète ou le romancier qui est ici étudié, mais l’auteur de nombreuses études sur la peinture et la pensée chinoises, et l’essayiste, le moraliste qui, depuis deux décennies, s’est tourné vers les questions qu’il juge essentielles dans notre monde actuel, en raison même de leur apparente inactualité : la mort, la beauté, l’âme, le dépassement de soi. L’article détaille une écriture de la médiation, du dialogue entre l’Extrême Orient et l’Occident qui a évolué vers une écriture de la confession et la méditation.

The aim of this study was to explore the profile of bioactive compounds of Merlot grape pomace by different methodologies including phenolic composition by spectrophotometry, chromatography and spectroscopy and its antibacterial activity. Additionally, the correlation between phenolic compounds and antioxidant activity by principal component analyses (PCA) was evaluated. Merlot grape pomace showed different classes of bioactive compounds such as phenolic acids, flavonoids and stilbene with high antioxidant activity according to the DPPH (2.58 ± 0.07 mg mL‑1), autoxidation of system β-carotene/linoleic acid (70.60 ± 0.91%), ABTS (1.22 ± 0.01 mg mL-1) and FRAP (23.83 ± 0.64 µM FeSO4 g-1) assays. The extracts showed minimum inhibitory concentration for gram-positive and gram-negative bacteria with high values for Bacillus cereus (MIC = 12.5 mg mL-1) and Staphylococcus aureus (MIC = 25 mg mL-1), respectively. In addition, fingerprint regions of the phenolic compounds were found by mid-infrared, supporting the results of the chromatographic analyses. Through the PCA, the antioxidant potential assays had high correlation with phenolic composition. Therefore, considering the significant concentrations of the different bioactive compounds found in Merlot grape pomace, it can be inferred that this cheap by-product can be reused by the food industry in the development of new products
On the presence of Scinax pedromedinae (Henle, 1991) (Amphibia: Anura: Hylidae) in Amazonian Brazil and northern Peru

Published: February 2022

We report the presence of Scinax pedromedinae in northern Peru, near the point where the borders of Peru, Brazil, and Colombia meet (660 km northeast of Pucallpa and 900 km N of Puerto Maldonado), and in the Estação Ecológica Mamirauá in central Amazonas State, Brazil (1,200 km NE of Pucallpa, 1,100 km NNE of Puerto Maldonado, and 600 km E of the northern Peruvian locality reported here). These new records suggest a continuous distribution of this species in the western Amazon Basin, in eastern Peru, western Brazil, and northern Bolivia.

Enriquecimento de florestas secundárias como tecnologia de produção sustentável para a agricultura familiar
Authors: Brienza Júnior Silvio 
Published: February 2022

A capacidade produtiva da agricultura tradicional de corte e queima pode ser melhorada por meio do plantio de árvores de crescimento rápido durante o período de pousio, com o objetivo de acumular biomassa e nutrientes para uso na fase agrícola subsequente. Para isso, são desejados alguns atributos das espécies florestais a serem usadas no enriquecimento da capoeira. O plantio das espécies florestais leguminosas Acacia mangium (acácia), Inga edulis (ingá), Acacia angustissima (ligeirinha) e Sclerolobium paniculatum (taxi-branco), a partir da fase agrícola (milho e mandioca), no espaçamento 2 m x 2 m, apresentou bons resultados para a porcentagem de sobrevivência, acúmulo de biomassa e volume de madeira. O acúmulo de biomassa seca proporcionado pelas árvores plantadas variou de 35-40 t ha-1 (acácia) a 10-15 t ha-1 (taxi-branco). A análise do impacto do enriquecimento na redução do tempo de pousio mostrou que o sistema de enriquecimento formado com A. mangium proporcionou, em três anos (um ano de cultivo agrícola + dois anos de pousio enriquecido), um acúmulo de biomassa equivalente a cinco anos de pousio tradicional.

A caracterização da paisagem da microbacia com o uso do sensoriamento remoto é essencial para o planejamento e conservação dos recursos naturais. Assim, objetivou-se com o presente trabalho realizar o levantamento das características da paisagem da microbacia do rio Jabuti e gerar dados para o desenvolvimento agropecuário sustentável. Os estudos geométricos, topográficos, hidrográficos e da dinâmica da cobertura vegetal foram realizados com o uso dos softwares QGIS, Google Earth e TrackMaker Free, imagens altimétricas (satélite ALOS) e de cobertura do solo (satélites Landsat 5 e Landsat 8), e análise da literatura. A área da microbacia é de 15,72 km2, perímetro de 20,06 km, formato alongado. Com base nas características geométricas a microbacia apresentou de baixa a média suscetibilidade a enchentes. A altitude foi de 266 a 349 m, o relevo predominantemente é suave ondulado (46,37%), seguido de ondulado (34,67%) e plano (15,39%), 89,44% da área apresentou baixo risco para propagação de incêndios e enquadrou-se como apta a extremamente apta a mecanização agrícola. A rede de drenagem é de 36,07 km com padrão dendrítico de 4ª ordem, densidades de nascentes média, densidade de drenagem alta, coeficiente de manutenção de 435,8 m2 m-1, canal principal muito reto e tempo de concentração baixo. A microbacia apresenta alto potencial para o desenvolvimento de atividades agropecuárias e de piscicultura, porém há a necessidade de adoção de práticas conservacionistas e estudos detalhados do ecossistema aquático. Sugere-se estudos para recuperação da vegetação nativa, principalmente em áreas de reserva legal.

Abstract
Importance: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system that produces both motor and cognitive dysfunctions. Impairments in limb function as a result of MS cause a decline in the performance of activities of daily living (ADLs).
Objective: To determine whether the use of mental practice (MP) or MP combined with training in motor manipulation skills (skills training) would improve gross and fine motor skills and treatment satisfaction among people with MS.
Design: Pilot study with a duration of 3 mo plus 3-mo follow-up.
Setting: Two MS associations.
Participants: Thirty-five patients diagnosed with MS of the relapsing–remitting and progressive secondary subtypes, ages 25 to 60 yr.
Intervention: The participants were allocated to one of three groups according to their order of inclusion in the study: (1) MP, (2) MP + skills training, or (3) control group. The treatment protocol had a 6-wk duration and a total of 12 sessions.
Outcomes and Measures: Blinded evaluators performed three assessments for each patient (pretreatment, posttreatment, and 3-mo follow-up) using the Nine-Hole Peg Test, Box and Block Test, ABILHAND, and Canadian Occupational Performance Measure (COPM).
Results: We found no evidence of benefits in self-perceived performance of ADLs with respect to gross and fine motor skills; however, there was an improvement in perceived satisfaction and in the performance of activities, independent of the treatment received.
Conclusions and Relevance: Perceived ADL performance and satisfaction with performance increases among people with MS when they receive MP, MP + skills training, and conventional rehabilitation treatment.
What This Article Adds: Mental practice combined with conventional treatment could contribute to patients perceiving improved performance of ADLs. Self-reported outcome measures, such as the COPM, could provide highly valuable information about occupation performance that may not match the objective evidence.

The method used in this research is a qualitative method with a qualitative descriptive approach. Based on the results of the analysis and interpretation of the data, an indication that the meaning of love from the composition "Una Limosnita Por El Amor de Dios" is reflected in the title and musical elements in the composition. The title of the song, which means "Charity for the Love of God" has the meaning of living in loving one another (Philia's love) to reflect God's love (Agape love). The elements that support the delivery of meaning in the composition of the song Una Limosnita Por El Amor de Dios are the use of minor scales and modulation to major notes, stepping melody intervals, tremolo ornaments throughout the song, intros which are accompaniment motifs along the song, there are along Picardy at the end of the repetition of the theme, the use of the plot is diminished before the major line at the end of the song, the dynamics that are played are based on the feelings of the player.
Rainfall erosivity mapping over mainland China based on high-density hourly rainfall records
Authors: Yue Tianyu , Yin Shuiqing , Xie Yun , Yu Bofu , Liu Baoyuan 
Published: February 2022

Abstract. Rainfall erosivity quantifies the effect of rainfall and
runoff on the rate of soil loss. Maps of rainfall erosivity are needed for
erosion assessment using the Universal Soil Loss Equation (USLE) and its
successors. To improve erosivity maps that are currently available, hourly
and daily rainfall data from 2381 stations for the period 1951–2018 were
used to generate new R-factor and 1-in-10-year event EI30 maps for
mainland China (available at
https://doi.org/10.12275/bnu.clicia.rainfallerosivity.CN.001; Yue et al.,
2020b). One-minute rainfall data from 62 stations, of which 18 had a record
length > 29 years, were used to compute the “true” rainfall
erosivity against which the new R-factor and 1-in-10-year EI30 maps
were assessed to quantify the improvement over the existing maps through
cross-validation. The results showed that (1) existing maps underestimated
erosivity for most of the south-eastern part of China and overestimated for
most of the western region; (2) the new R-factor map generated in this study
had a median absolute relative error of 16 % for the western region,
compared to 162 % for the existing map, and 18 % for the rest of China.
The new 1-in-10-year EI30 map had a median absolute relative error of
14 % for the central and eastern regions of China, compared to 21 % for
the existing map (map accuracy was not evaluated for the western region
where the 1 min data were limited); (3) the R-factor map was improved mainly
for the western region, because of an increase in the number of stations
from 87 to 150 and temporal resolution from daily to hourly; (4) the benefit
of increased station density for erosivity mapping is limited once the
station density reached about 1 station per 10 000 km2.
An approach for constraining mantle viscosities through assimilation of palaeo sea level data into a glacial isostatic adjustment model
Authors: Schachtschneider Reyko , Saynisch-Wagner Jan , Klemann Volker , Bagge Meike , Thomas Maik 
Published: February 2022

Abstract. Glacial isostatic adjustment is largely governed by the rheological
properties of the Earth's mantle. Large mass redistributions in the
ocean–cryosphere system and the subsequent response of the
viscoelastic Earth have led to dramatic sea level changes in the
past. This process is ongoing, and in order to understand and predict
current and future sea level changes, the knowledge of mantle
properties such as viscosity is essential. In this study, we present a
method to obtain estimates of mantle viscosities by the assimilation of
relative sea level rates of change into a viscoelastic model of the
lithosphere and mantle. We set up a particle filter with probabilistic
resampling. In an identical twin experiment, we show that mantle
viscosities can be recovered in a glacial isostatic adjustment model
of a simple three-layer Earth structure consisting of an elastic
lithosphere and two mantle layers of different viscosity. We
investigate the ensemble behaviour on different parameters in the following three set-ups: (1) global observations data set since last glacial maximum
with different ensemble initialisations and observation uncertainties,
(2) regional observations from Fennoscandia or Laurentide/Greenland
only, and (3) limiting the observation period to 10 ka until the
present. We show that the recovery is successful in all cases if the
target parameter values are properly sampled by the initial ensemble
probability distribution. This even includes cases in which the target
viscosity values are located far in the tail of the initial ensemble
probability distribution. Experiments show that the method is
successful if enough near-field observations are available. This makes
it work best for a period after substantial deglaciation until the present
when the number of sea level indicators is relatively high.

Authors: Hai Le Thi Thu , Phuong Bui Thi Thu 
Published: February 2022

Background: Melasma is a common acquired, chronic hypermelanosis, more common in women and dark skin types, less dangerous but greatly affects aesthetics. The picosecond laser have been used with good effectiveness on melasma. Objective: To evaluate the efficacy and safety of a picosecond laser (Picoplus, Lutronic, Korea) on patients with melasma. Subject and method: We conducted a comparative longitudinal descriptive study in 58 dermal and mixed melasma patients (100% females), middle-aged, with initial severe MASI underwent treatments in 108 Military Central Hospital from 7/2017 to 12/2018 with picosecond laser. Result: Good/excellent improvement 28.9%, fair 42.2% after 8 treatment sessions. All most patient was no side effect, only 3.4% patients had temporary burning sensation. Conclusion: Treatment of melasma using a picosecond laser is an effective and safe method. However, the disadvantage of the method is the multistage procedure.
