A new steady-state gas–particle partitioning model of polycyclic aromatic hydrocarbons: implication for the influence of the particulate proportion in emissions
Authors: Zhu Fu-Jie , Hu Peng-Tuan , Ma Wan-Li
Published: August 2023

Abstract. Gas–particle (G–P) partitioning is a crucial atmospheric process for semi-volatile organic compounds (SVOCs), particularly polycyclic aromatic hydrocarbons (PAHs). However, accurately predicting the G–P partitioning of
PAHs has remained a challenge. In this study, we established a new
steady-state G–P partitioning model based on the level-III multimedia
fugacity model, with a particular focus on the particulate proportion
(ϕ0) of PAHs in emissions. Similar to previous steady-state
models, our new model divided the G–P partitioning behavior into three domains based on the threshold values of log KOA (octanol–air partitioning coefficient), with slopes of 1, from 1 to 0, and 0 for the three domains. However, our model differed significantly from previous models in different domains. We found that deviations from the equilibrium-state G–P partitioning models were caused by both gaseous interference and
particulate interference, with ϕ0 determining the influence of
this interference. Different forms of the new steady-state model were
observed under different values of ϕ0, highlighting its
significant impact on the G–P partitioning of PAHs. Comparison of the G–P partitioning of PAHs between the prediction results of our new steady-state model and monitored results from 11 cities in China suggested varying prediction performances under different values of ϕ0, with the lowest root mean square error observed when ϕ0 was set to 0.9 or 0.99. The results indicated that the ϕ0 was a crucial factor for
the G–P partitioning of PAHs. Furthermore, our new steady-state model also demonstrated excellent performance in predicting the G–P partitioning of
PAHs with entirely gaseous emission and polybrominated diphenyl ethers with
entirely particulate emission. Therefore, we concluded that the ϕ0 should be considered in the study of G–P partitioning of PAHs, which
also provided a new insight into other SVOCs.

Abstract. We here describe, document, and make available a wide range of data sets used for annual-layer identification in ice cores from DYE-3, GRIP, NGRIP,
NEEM, and EGRIP. The data stem from detailed measurements performed both on the main deep cores and shallow cores over more than 40 years using many
different setups developed by research groups in several countries and comprise both discrete measurements from cut ice samples and continuous-flow
analysis data. The data series were used for counting annual layers 60 000 years back in time during the construction of the Greenland Ice-Core Chronology 2005
(GICC05) and/or the revised GICC21, which currently only reaches 3800 years back. Now that the underlying data are made available (listed in Table 1) we also release
the individual annual-layer positions of the GICC05 timescale which are based on these data sets. We hope that the release of the data sets will stimulate further studies of the past climate taking advantage of these highly resolved data series
covering a large part of the interior of the Greenland ice sheet.
Thirty-meter map of young forest age in China
Authors: Xiao Yuelong , Wang Qunming , Tong Xiaohua , Atkinson Peter M.
Published: August 2023

Abstract. Young forest age mapping at a fine spatial resolution is important
for increasing the accuracy of estimating land–atmosphere carbon fluxes and
guiding forest management practices. In recent decades, China has actively
conducted afforestation and forest protection projects, thereby laying the
foundation for the realization of carbon neutrality. However, very few
studies have been conducted which map the ages of young forests for the
whole of China at a fine spatial resolution. In this research, a continuous
change detection and classification (CCDC)-based method suitable for
large-scale forest age mapping is proposed and used to estimate young forest ages across China in 2020 at a spatial resolution of 30 m. First, a
10 m spatial-resolution land cover dataset (WorldCover2020) from the
European Space Agency (ESA) was used to determine the forest cover areas in
2020. Then, the CCDC algorithm was used to identify stand-replacing
disturbances to determine the stand age based on 436 967 Landsat tiles
across China from 1990 to 2020. A validation sample set composed of multiple
land use and land cover (LULC) products was used to calculate the overall
accuracy (OA) of the 2020 young forest age (1–31-year) map of China, and
the OA was 90.28 %. The reliability and applicability of the proposed
CCDC-based forest age mapping method were validated by comparing the forest
age map with Hansen's forest change dataset, Max Planck Institute for
Biogeochemistry (MPI-BGC) 1 km global forest age datasets, and field
measurements. The CCDC-based method has strong application potential in
real-time mapping of the age of young forests at the global scale. The
produced forest age map provides a basic dataset for research on the forest
carbon cycle and forest ecosystem services as well as important guidance for
government departments, such as the National Forestry and Grassland
Administration and the National Development and Reform Commission in China. Data presented in this study is available at https://doi.org/10.6084/m9.figshare.21627023.v7 (Xiao, 2022).

Abstract. Nineteen years of atmospheric composition measurements
made at the University of Toronto Atmospheric Observatory (TAO;
43.66∘ N, 79.40∘ W; 174 m a.s.l.) are presented. These
are retrieved from Fourier transform infrared (FTIR) solar absorption
spectra recorded with an ABB Bomem DA8 spectrometer from May 2002 to
December 2020. The retrievals have been performed for 14 species:
O3, HCl, HF, HNO3, CH4, C2H6, CO, HCN, N2O,
C2H2, H2CO, CH3OH, HCOOH, and NH3 using the
SFIT4 algorithm. The measurements have been archived in the Network for
the Detection of Atmospheric Composition Change (NDACC) data repository in
Hierarchical Data Format version 4 (HDF4) files following the Generic Earth
Observation Metadata Standard (GEOMS) and are also publicly available on
Borealis, the Canadian Dataverse Repository (https://doi.org/10.5683/SP2/VC8JMC, Yamanouchi et al., 2022). In this paper, we describe the
instrumentation, the retrieval strategy, the vertical sensitivity of the
retrievals, the quality assurance process, and the error analysis of the TAO
FTIR measurements and present the current version of the time series.

Published: August 2023

Abstract. Mud volcanoes are fluid escape structures allowing for surface venting of hydrocarbons (mostly gas but also liquid condensates and oils) and water–sediment slurries. For a better understanding of mud volcano dynamics, the characterization of the fluid dynamics within mud volcano conduits; the presence, extent, and depth of the fluid reservoirs; and the connection among aquifers, conduits, and mud reservoirs play a key role. To this aim, we performed a geoelectrical survey in the Nirano Salse Regional Nature Reserve, located at the edge of the northern Apennines (Fiorano Modenese, Italy), an area characterized by several active mud fluid vents. This study, for the first time, images the resistivity structure of the subsoil along two perpendicular cross sections down to a depth of 250 m. The electrical models show a clear difference between the northern and southern sectors of the area, where the latter hosts the main discontinuities. Shallow reservoirs, where fluid muds accumulate, are spatially associated with the main fault/fracture controlling the migration routes associated with surface venting and converge at depth towards a common clayey horizon. There is no evidence of a shallow mud caldera below the Nirano area. These findings represent a step forward in the comprehension of the Nirano Salse plumbing system and in pinpointing local site hazards, which promotes safer tourist access to the area along restricted routes.

Published: August 2023

The elderly patients are currently the main occupants of acute hospital beds, and this trend will likely increase as the world ages. The elderly patients with cognitive issues frequently have behavioural symptoms which may be challenging for the care staff to manage, especially the staff who have not been formally trained in Gerontology. The use of restraints for this group of vulnerable patients should be discouraged as restraints can cause harmful effects. The use of iPads as a non-pharmacological strategy for managing the behavioural symptoms among the elderly in-patients with cognitive issues was effective in reducing agitation, with an improvement in mood and sundown symptoms. The patients were actively and meaningfully engaged with their iPads during therapy. The nursing staff too, benefited from iPads as a novel therapy for their elderly in-patients with cognitive issues in providing cognitive and social stimulations, which they had no time to provide for. While the patients showed improvement in their behavioural symptoms, the nurses’ stress levels reduced with an improved self-reported job satisfaction.

Deep structure of the Earth's crust in South Bulgaria: geological aspects
Authors: Zagorchev Ivan
Published: August 2023

The layered structure of the Earth's crust in South Bulgaria is a result of the complicated geologic development, and of changes in the physical properties of the rocks under high pressures and temperatures. The following layers are distinguished (from bottom to top): Layer "A" (dehydrated lower crust) with layer velocities from 6.4 to 6.7 km/s, and characterized by low-velocity ductile deformations: Layer "B" (hydrated upper crust) with layer velocities 5.9–6.0 km/s, and characterized by homogeneous strains, as well as by deformations by cataclastic flow; low-velocity layer which developed only partially in the west part of Rhodope Massif, and is deformed by superplastic flow; presumably, it compensated differently directed movements in adjacent layers during some deformational stages; granitoid-metamorphic crust characterized mainly by brittle deformations. This structure probably resulted from multiphase deformations during several tectonic cycles. The dynamic environment changed considerably, compression stages being replaced by extension stages; in some stages different crust layers behaved differently, e. g. with an extension environment in the granitoid-metamorphic crust, and compression – within the deeper levels. Crustal thickening is due to different mechanisms but has been bound mainly to continental collision. With reaching a crytical thickness, isostasy-bound uplift led to thinning by erosion. Other mechanisms of crustal thinning are bound to environments of generalized extension and rifting, homogeneous deformation, or non-homogeneous ductile deformation with necking. As a result of multiphase crustal thickening, Rhodope Massif formed as a peculiar crustal lensoid body. The collisional orogen on the Balkan Peninsula, at least during the Alpine cycle, had a transitional character – from Alpine towards the Himalayan-Tibethan type, the Rhodope Massif playing the part of plateau.

Tradisi lisan ini awalnya merupakan sebuah ungkapan hati seseorang yang dikemas dalam bentuk pertunjukan seni. Kesenian Senjang banyak berkembang di wilayah Kabupaten Musi Banyuasin, antara lain di Kecamatan Sungai Keruh, Kecamatan Babat Toman, Kecamatan Sanga Desa, dan Kecamatan Sekayu. Masing-masing wilayah memiliki kekhasan iramanya sendiri-sendiri. Meski kesenian Senjang populer di wilayah Kabupaten Musi Banyuasin dan para pelantunnya pun mayoritas berasal dari wilayah tersebut, tetapi tidak dapat dipastikan bahwa Kesenian Senjang berasal dari daerah ini. Sebab, Kesenian Senjang juga tumbuh dan berkembang di daerah lainnya di bagian hulu Sungai Musi. Senjang adalah salah satu bentuk media seni budaya yang menghubungkan antara orang tua dan generasi muda, serta antara masyarakat dan pemerintah. Hal yang disampaikan dapat berupa nasihat, kritik, aspirasi, maupun ungkapan rasa gembira. Masalah yang menjadi latar belakang penelitian ini karena kepandaian Senjang serupa itu sudah sangat langka.

Lentil, Lens culinaris (syn: Lens esculenta), is one of the most important annual legumes from the Fabaceae family, which is widely cultivated throughout Asia, Europe, Northern America, Australia, and North Africa. Lentil seeds are mostly used in food industries to produce soups and its fodder is used as livestock feed. Ascochyta blight of lentil (ABL), which is caused by the pathogenic fungus Ascochyta lentis(teleomorph Didymella lentis), is one of the important diseases of this crop worldwide which causes serious damage to it. Resistance of different lentil varieties to this disease is variable. For this purpose, different studies have been performed on resistance in cultivated and wild varieties against this disease; some of them have focused on ecological aspects, others on genetics, and few on pathogen virulence. In this review, we have outlined the advantages of each background along with latest research. The present review, due to its unique characteristics which has been done to our knowledge for the first time, can be considered as valuable regarding the management of this dangerous disease in lentil.

There have been disturbing waves of Covid-19 deaths in many countries due to a lack of adequate treatment in the early stages of the pandemic but also to the presence of co-morbidities in many hospitalised patients. This work aims to determine the discriminatory features between the surviving patients and the deceased ones after their hospitalisation to propose a new method of prognosis on the outcome of a new patient under treatment. To this end, we use three supervised classification methods, each allowing us to select the most significant features associated with patient death. These are binary logistic regression (BLR), random forests (RF), and support vector machines (SVM). The data comes from the Ministry of Health and Social Action of Senegal and covers the period from March 2020 to December 2022. Age emerged as the most discriminatory factor between the two patient groups: survivors and deceased. The study found that patients 60 and older are more likely to die of Covid-19.
