In this research the efficient and low computation complex signal acclimatizing techniques are projected for the improvement of Electroencephalogram (EEG) signal in remote health care applications. In clinical practices the EEG signal is extracted along with the artifacts and with some small constraints. Mainly in remote health care situations, we used low computational complexity filters which are striking. So, for the improvement of the EEG signal we introduced efficient and computation less Adaptive Noise Eliminators (ANE’s). These techniques simply utilize addition and shift operations, and also reach the required convergence speed among the other predictable techniques. The projected techniques are executed on real EEG signals which are stored and are compared with the effecting EEG arrangement. Our realizations visualize that the projected techniques offer the best concert over the previous techniques in terms of signal to noise ratio, mathematical complexity, convergence rate, Excess Mean Square error and Mis adjustment. This approach is accessible for the brain computer interface applications.

Mobile Ad-hoc Network is the self-configuring structure less network for transmitting the information from one node to another node because of the independent node direction. During the information transmission in the network one of the main challenges is to maintain the intermediate node information for making the effective transmission. In addition the intermediate person may be hacking the information by performing the Wormhole and Black hole attacks. So, in this paper proposes an effective Neighboring Relationship based Clustering protocol. The protocol analyzes the neighboring relationship between the transmitted node information protocols. Each similar node information is grouped into the cluster. At the time cluster head and neighboring node topology has been updated continuously for avoiding the middle man attacks like, wormhole and black hole. Further the energy consumption is managed by applying the Fireflies algorithm based Energy efficient routing protocol with efficient manner. Then the efficiency of the system is analyzed using the experimental results like, packet delivery ratio, energy utilization factor and percentage of attack free routing efficiency.

This paper is presented to bring a very important issue in the data transmission realm ‘congestion’. Regardless of the type and priority of the data it may happen that a lot of signals generate by the system of sensors arrive at the ‘root’ destination at the same time. Regardless of the processing power sometimes it has been observed that spectrum gets saturated. This saturation can be compared with large crowd trying to get into stadium through one entry point. To solve this problem various algorithms have been introduced, in this paper we have given emphasis on one algorithms one is signal-type priority reception. The Quality-of-Service (QoS) of the primary applications is of vital issue in order to ensure its efficiency and robustness. WSN's with limited resources, congestion in WSN will further reduce the expected QoS by degrading its services and contributions in monitoring systems. In this state, efficient use of the scarce resources is an important to ensure seamless data transmission. At a sensor node the power consumption can be reduced by reducing the packet retransmission rate which can be caused by congestion. The nodes deployed in the area monitored will be clustered groups with a cluster head. The proposed technique is able to reduce congestion thus improve the overall performance. This algorithm will give a major boost to WSN system employing ‘n’ number of sensors and be able to boost up efficiency and cut down the time delay and hence enhancing the productivity of the system itself.

Emotion plays a critical job ineffectively conveying one’s convictions and intentions. As an outcome, identification of emotion has turned into focus point of few studies recently. Patient observing models are getting to be significant in patient concern and can endow with helpful feedback related to health issues for caregivers and clinicians. In this work, patient fulfilment recognition framework is proposed that uses image frames extracted from the recorded visual-audio modality dataset. The images are treated with techniques such as Local Binary Pattern (LBP) which is a ocular descriptor. The proposed framework incorporates feature extraction from the images and then the Support Vector Machine (SVM) is applied for classification. The three distinct types of emotions are whether the patient is happy, sad or neutral and the same are detected based on the results. The result of such an analysis can be made use of by a group of analysts which include doctors, healthcare experts and system experts to improve smart healthcare system in steps. The reliability of information provided by such a system makes such upgradations more meaningful.

Human body structure is very complex, which contains various sub-components and makes it a complicated system. There are various activities performed by humans which involves both mental and physiological activities. Additionally, to monitor human health conditions various waves are examined like brainwaves, heart waves and others, which are highly useful in clinical scrutiny. Likewise, there exists an organized field of energy associated with every individual, termed as human biofield. This human biofield comprises of pre-eminent information about one’s health and psychological state. Moreover, several studies manifested the evidences of its existence and its benefits clinically together with numerous alliances. This augments the importance of this field and reveals diversified applications in Complementary and Alternative Medicine (CAM) for humans. Contrary to other biological signals for instance ECG, EEG and other, biofield still is not being mapped i.e. no measurement techniques are available for calculating the impact of Biofield in diagnosis and therapy, due to the uneven characteristics of biofield. This research article deals with the description of hitherto journey of biofield, including its concepts, imaging and applications. Further, this paper also imparts the need of Artificial intelligence stating new opportunities and challenges associated with it.

Published: August 2019

Background: High-dose heparin occasionally causes severe hypotension during cardiothoracic surgery. Being able to predict the severity of the decrease in blood pressure prior to administration of heparin would improve hemodynamic and anesthetic management. The aim of this study was to investigate the predictors of heparininduced hypotension and the effects of high-dose heparin on various hemodynamic and physiologic parameters.Methodology: The records of adult patients who underwent elective cardiothoracic surgery at University of Yamanashi Hospital between January 2016 and December 2017 were retrospectively reviewed. Single and multiple linear regression analyses were conducted to identify the predictors of heparin-induced hypotension. Results: High baseline systemic vascular resistance index (SVRI) and non-use of preoperative antihypertensive medication were significant predictors of heparininduced hypotension with a following regression equation: Percent change in mean arterial pressure = 17.273 + 0.00457 × (baseline SVRI) - 14.043 × (antihypertensive medication), where antihypertensive medication is coded as 0 = no antihypertensive drug and 1 = one or more antihypertensive drug(s), F = 7.80, the multiple correlation coefficient is 0.68645, and R adjusted for degrees of freedom is 0.41078.Conclusion: The baseline SVRI and non-use of preoperative antihypertensive medication are significant predictors of the severity of heparin-induced hypotension.Abbreviations: MAP - Mean arterial blood pressure; CVP - central venous pressure; PAP - pulmonary arterial pressure; SVRI - systemic vascular resistance index; BMI: body mass index; ASA-PS: American Society of Anesthesiologists physical status classification; DM: diabetes mellitus; eGFR: estimated glomerular filtration rate; LVEF: left ventricular ejection fraction; EDVI: end-diastolic volume index; CI: cardiac index; SvO2: mixed venous oxygen saturation; LVEF: left ventricular ejection fraction; HR: heart rate.

Authors: Afridi Nighat , Fareed Amna , Fatima Ambreen
Published: August 2019

Background and Aims: Post-dural puncture headache (PDPH) is a common cause of morbidity in patients subjected to dural puncture for spinal anesthesia. PDPH is mostly a benign condition but can lead to delayed hospital discharge and considerable morbidity for the parturient. We aimed to study whether there is a positive role of prednisolone in post dural puncture headache management (after spinal anesthesia) in patients undergoing lower segment cesarean section (LSCS). Methodology: A randomized controlled trial was conducted at department of gynecology and obstetrics, in Combined Military Hospital (CMH), Nowshera, from April 2018-September 2018. A sample size of 60 patients was determined through WHO calculator. Patients were selected through non probability consecutive sampling after ethical committee approval and consent forms were taken. Patients were randomly categorized into two groups. Group A was given tablet prednisolone while Group B was given a placebo tablet. Patients were followed for pain measurement using visual analogue scale (VAS). Data were analyzed using SPSS version 24. T-test and Chi-square test were applied. A p ≤ 0.05 was considered significant.Results: A total of 60 women undergone c sections were included in study. Mean age of women was 28.5 years ± 4.3. Mean pain scores were significantly reduced in prednisolone group as compared to placebo at 24, 48, 72 and 96 h (p = 0.00). Majority of patients in placebo group had severe headache as compare to oral prednisolone group after 96 h (p = 0.00).Conclusion: Post-Dural Puncture Headache is a major complications following LSCS in spinal anesthesia. Oral prednisolone usage is very effective in lowering severity of headache and duration of PDPH. Oral prednisolone also limits adverse events associated with PDPH after LSCS performed in spinal anesthesia.Citation: Afridi N, Fareed A, Fatima A, Role of prednisolone in management of postdural puncture headache after spinal anesthesia in obstetric patients .

Published: August 2019

Objective: The study aimed to assess diaphragmatic thickness measurement by B-mode ultrasound for prediction of extubation and proper timing of weaning from mechanical ventilation in cancer patients admitted to the intensive care unit after major surgery.Methodology: A prospective, longitudinal study conducted at Surgical ICU, National Cancer Institute, Cairo University, Cairo. Fifty patients were recruited during the immediate postoperative period after major elective cancer surgery who needed mechanical ventilation (MV). Patients were enrolled when judged to be eligible for a test of weaning from MV according to clinical and arterial blood gases (ABG) criteria. The patient was assessed for weaning according to rapid shallow breathing index (RSBI) and ultrasound guided measurements of diaphragmatic thickness (tdi) during inspiration and expiration. The percent change in tdi between end-expiration and end-inspiration (Δtdi%) was calculated. The primary outcome measure was diagnostic accuracy of tdi and Δtdi% to predict weaning compared to ABG analysis (the gold standard for weaning).Results: After 48 hours, 13 patients were weaned according to ABG criteria. Kappa value (agreement) between RSBI and ABG was 0.974. Kappa between both tdi and Δtdi% and the ABG criteria was 0.891. The values differed slightly in patients tested after 72 hours. Sensitivity of a cut off level of tdi of 2 mm was 84.6% and 83.3% after 48 and 72 hours of MV, respectively. Sensitivity of Δtdi% of 20% was clearly higher after 72 hours (95.8%). Using ROC curves, Δtdi% of > 29.5% was also more sensitive after 72 hours.Conclusion: Ultrasound estimation of diaphragm function is a promising tool to help clinicians to judge weaning readiness in patients on mechanical ventilation following major cancer surgery. Diaphragm thickness and its change between end-expiration and end-inspiration showed high degree of agreement with arterial blood gases for predicting weaning readiness.Abbreviations: RSBI: Rapid shallow breathing index, MV: mechanical ventilation, tdi: diaphragm thickness, Δtdi%: percent change in tdi between end-expiration and end-inspiration, PPV: positive predictive value, NPV: negative predictive value, kappa: measure of agreement, NCI: National Cancer Institute, VIDD: ventilator-induced diaphragmatic dysfunctionCitation: Soliman AM, Samy MA, Heikal AM, El Ramely MA, Kotb TA.

Anatomical gates for pain relief due to cervical and lumbar disc disease
Authors: Hammodi Amjed
Published: August 2019

I propose the theory that the nerve sheath is transmitting the lignocaine chemical upwards towards the dorsal root ganglia and nerve roots which produce pain due to excitation after the disc disease. In this way, an injection of local anesthetic given far away from the actual neural damage, at a peripheral site, can relieve the pain for a variable length of time. In this case report, the author describes four specific injection points, called ‘Gates’; two of these describe pain relief in neck and upper limb, while two are specific to low back pain, hip pain and lower limb pains. Each of these was successfully used in a patient with specific pain of variable duration. Certainly, controlled studies with larger sample size, are needed to be done to understand better that how these distal nerve blocks really work.Citation: Hammodi A.

Although the

transition of [C ii] at λ ≃  158

is known to be an excellent tracer of active star formation, we still do not have a complete understanding of where within star formation regions the emission originates. Here, we use SOFIA upGREAT observations of [C ii] emission toward the H ii region complex Sh2-235 (S235) to better understand in detail the origin of [C ii] emission. We complement these data with a fully sampled Green Bank Telescope radio recombination line map tracing the ionized hydrogen gas. About half of the total [C ii] emission associated with S235 is spatially coincident with ionized hydrogen gas, although spectroscopic analysis shows little evidence that this emission is coming from the ionized hydrogen volume. Velocity-integrated [C ii] intensity is strongly correlated with Wide-field Infrared Survey Explorer (WISE) 12

intensity across the entire complex, indicating that both trace ultraviolet radiation fields. The 22

and radio continuum intensities are only correlated with [C ii] intensity in the ionized hydrogen portion of the S235 region and the correlations between the [C ii] and molecular gas tracers are poor across the region. We find similar results for emission averaged over a sample of external galaxies, although the strength of the correlations is weaker. Therefore, although many tracers are correlated with the strength of [C ii] emission, only WISE 12

emission is correlated on small scales of the individual H ii region S235 and also has a decent correlation at the scale of entire range of galaxies. Future studies of a larger sample of Galactic H ii regions would help to determine whether these results are truly representative.
Characterizing the Local Relation between Star Formation Rate and Gas-phase Metallicity in MaNGA Spiral Galaxies

Published: August 2019

The role of gas accretion in galaxy evolution is still a matter of debate. The presence of inflows of metal-poor gas that trigger star formation bursts of low metallicity has been proposed as an explanation for the local anticorrelation between star formation rate (SFR) and gas-phase metallicity (Z

g
) found in the literature. In the present study, we show how the anticorrelation is also present as part of a diversified range of behaviors for a sample of more than 700 nearby spiral galaxies from the SDSS-IV MaNGA survey. We have characterized the local relation between SFR and Z

g
after subtracting the azimuthally averaged radial profiles of both quantities. Of the analyzed galaxies, 60% display an SFR–Z

g
anticorrelation, with the remaining 40% showing no correlation (19%) or positive correlation (21%). Applying a random forest machine-learning algorithm, we find that the slope of the correlation is mainly determined by the average gas-phase metallicity of the galaxy. Galaxy mass, g − r colors, stellar age, and mass density seem to play a less significant role. This result is supported by the performed second-order polynomial regression analysis. Thus, the local SFR–Z

g
slope varies with the average metallicity, with the more metal-poor galaxies presenting the lowest slopes (i.e., the strongest SFR–Z

g
anticorrelations), and reversing the relation for more metal-rich systems. Our results suggest that external gas accretion fuels star formation in metal-poor galaxies, whereas in metal-rich systems, the gas comes from previous star formation episodes.

The width of the broad emission lines in quasars is commonly characterized by either the FWHM or the square root of the second moment of the line profile (σ
line) and used as an indicator of the virial velocity of the broad-line region (BLR) in the estimation of black hole (BH) mass. We measure FWHM and σ
line for Hα, Hβ, and Mg ii broad lines in both the mean and rms spectra of a large sample of quasars from the Sloan Digital Sky Survey Reverberation Mapping project. We introduce a new quantitative recipe to measure σ
line that is reproducible, is less susceptible to noise and blending in the wings, and scales with the intrinsic width of the line. We compare the four definitions of line width (FWHM and σ
line in mean and rms spectra, respectively) for each of the three broad lines and among different lines. There are strong correlations among different width definitions for each line, providing justification for using the line width measured in single-epoch spectroscopy as a virial velocity indicator. There are also strong correlations among different lines, suggesting that alternative lines to Hβ can be used to estimate virial BH masses. We further investigate the correlations between virial BH masses using different line width definitions and the stellar velocity dispersion of the host galaxies and the dependence of line shape (characterized by the ratio FWHM/σ
line) on physical properties of the quasar. Our results provide further evidence that FWHM is more sensitive to the orientation of a flattened BLR geometry than σ
line, but the overall comparison between the virial BH mass and host stellar velocity dispersion does not provide conclusive evidence that one particular width definition is significantly better than the others.

Published: August 2019

Two new species of the mayfly family Oligoneuriidae are described based on larval specimens recently collected in Iran. The first new species, Oligoneuriella tuberculata Godunko & Staniczek, sp. nov., can be distinguished from all its congeners by the presence of pronounced protuberances posteromedially on abdominal terga, highly reduced paracercus, large lamella of gill I, and setation on hind margin of middle and hind femora confined to their basal halves. The second species, Oligoneuriopsis villosus Bojková, Godunko, & Staniczek, sp. nov., remarkably belongs to a mostly Afrotropical genus. The new species clearly differs from all its congeners in the shape of setae on the surface of gills and terga, pattern of body colouration, and the shape of posterolateral projections of abdominal segments. Except for the species description, the generic diagnosis of Oligoneuriopsis Crass, 1947 is briefly discussed. COI barcode sequences of both new species are provided and molecular species delimitation is tested using distance-based and likelihood-based approaches, with both new species unambiguously recognised as separate lineages. The analysis of COI also corroborates the respective affinities of both new species, estimated based on morphology. The two new species of Oligoneuriidae described herein highlight the importance of the Middle East as a centre of diversity of this mayfly family within the Palaearctic.
BATF-Interacting Proteins Dictate Specificity in Th Subset Activity

Published: August 2019

The basic leucine zipper (bZIP) transcription factor BATF is expressed in multiple Th subsets and cooperates with other factors to regulate gene transcription. BATF activates lineage-specific cytokines in Th subsets, activating IL-9 in Th9 cells and IL-17 in Th17 cells, but not IL-9 or IL-17 in the reciprocal subset. The mechanism for this restricted activity is unclear. In this report, we define BATF binding partners that contribute to Th subset–specific functions. Although BATF and IRF4 are expressed in greater amounts in Th9 than Th17, increased expression of both factors is not sufficient to induce IL-9 in Th17 cells. BATF also requires heterodimer formation with Jun family members to bind DNA and induce gene expression. Using primary mouse T cell culture, we observed that JunB and c-Jun, but not JunD, promote IL-9 production in Th9 cells. Ectopic expression of BATF with either JunB or c-Jun generates modest, but significant, increases in IL-9 production in Th17 cells, suggesting that the low expression of Jun family members is one factor limiting the ability of BATF to induce IL-9 in Th17 cells. We further identified that Bach2 positively regulates IL-9 production by directly binding to the Il9 gene and by increasing transcription factor expression in Th9 cells. Strikingly, cotransduction of Bach2 and BATF significantly induces IL-9 production in both Th9 and Th17 cells. Taken together, our results reveal that JunB, c-Jun, and Bach2 cooperate with BATF to contribute to the specificity of BATF-dependent cytokine induction in Th subsets.

Published: August 2019

This workshop brought together experts in modeling and analysis of organising principles of multiscale biological systems such as cell assemblies, tissues and populations. We focused on questions arising in systems biology and medicine which are related to emergence, function and control of spatial and inter-individual heterogeneity in population dynamics. There were three main areas represented of differential equation models in mathematical biology. The first area involved the mathematical description of structured populations. The second area concerned invasion, pattern formation and collective dynamics. The third area treated the evolution and adaptation of populations, following the Darwinian paradigm. These problems led to differential equations, which frequently are non-trivial extensions of classical problems. The examples included but were not limited to transport-type equations with nonlocal boundary conditions, mixed ODE-reaction-diffusion models, nonlocal diffusion and cross-diffusion problems or kinetic equations.

In this work, a detailed study on the electrochemical degradation of an azo dye, Orange G is performed using a platinum electrode. Indeed, the influence of the dye concentration (50-150 mg/L), the pH of the medium and the density of the electric current is studied on the rate of discoloration, the rate of mineralization, the efficiency of the electric current and the energy consumption. The UV-visible spectra of OG plotted against the degradation time show the decrease of the intensity of the characteristic dye peaks. In an environment rich in chlorides, all peaks disappear after 15 min of degradation. However, the peaks at wavelengths of 200 and 290 nm appeared after one hour of treatment. In K2SO4, the eliminated percentages are respectively 46, 54 and 61% for wavelengths of 245, 330 and 480 nm. This suggests that the degradation mechanisms in K2SO4 and KCl environments are not the same. In the middle rich in chlorides, the eliminated percentage of OG did not seem to be affected by the concentrations increase. These results confirm the hypothesis that electrochemical oxidation process is very favorable for concentrated pollutants discharge.

Published: August 2019

In the present study, dye decolorizing bacteria were isolated from water and soil samples, collected from textile industries in Jodhpur province, India. Two bacterial species namely, Bacillus pumilis and Paenibacillus thiaminolyticus were screened and identified based on biochemical characterization. The degradation efficiency of these two microorganisms was compared through optimization of pH, incubation time, initial dye concentration and inoculum size. B. pumilis and P. thiominolyticus were able to degrade 61% and 67% Red HE3B, 81% and 75% Orange F2R, 49.7% and 44.2% Yellow ME4GL and 61.6% and 59.5% Blue RC CT dyes of 800mg/l concentration respectively. The optimum pH and time were found to be 8 within 24 hours. The FT-IR analysis confirmed that microorganisms were able to degrade toxic azo dyes into a non-toxic product as proved through structural modifications to analyze chemical functions in materials by detecting the vibrations that characterize chemical bonds. It is based on the absorption of infrared radiation by the microbial product. Therefore, Bacillus pumilis and Paenibacillus thiaminolyticus are a promising tool for decolorization of dyes due to its potential to effectively decolorize higher azo dye concentrations (10-800 mg/L) and can be exploited for bioremediation.
Para (re)ler “Vozes-mulheres”: Conceição Evaristo e a dialética da ancestralidade

Published: August 2019

O presente artigo tem por objetivo apresentar uma leitura para “Vozes-mulheres”, um dos mais conhecidos poemas de Conceição Evaristo, publicado originalmente no livro Poemas da recordação e outros movimentos. Por intermédio de uma leitura em profundidade, que leve em consideração também o conjunto de elementos retóricos, formais e rítmicos presentes na composição, aqui se tenciona abordar o modo como o referido poema apresenta um complexo processo dialético, protagonizado exclusivamente por figuras femininas – a saber: a bisavó, a avó, a mãe, o próprio eu lírico e sua filha –, ao longo do qual estas alcançam a determinação de sua própria liberdade. Por conseguinte, neste artigo o que se pretende é não apenas apresentar uma inovadora leitura para “Vozes-mulheres”, mas também contribuir de modo significativo para a fortuna crítica acerca da significativa produção poética de Conceição Evaristo – que, a despeito de sua importância, vem atraindo menos atenção de pesquisadores do que sua obra em prosa.

Purpose

To evaluate in three dimensions (3D) the human endosalpinx and reconstruct its surface along its different anatomical segments, without the injection or insertion of luminal contrasts, using confocal microtomography (micro-CT).

Material and methods

15 fallopian tubes (FT) from 14 women in reproductive age from procedures for benign disease or sterilization were selected. The specimens were fixed in formalin and stained with Lugol solution. Micro-CT studies were conducted on the specimens using protocols adapted from biological studies, to acquire images to reconstruct in 3D the endosalpinx surface.

Results

From these specimens, 6 presented the intra-mural segment, 14 presented the isthmus and 15 presented the ampulla and fimbria segment of the FT. The specimen presented tissue definition, and contrast sufficient for FT endosalpinx morphological analysis and lumen definition. The intramural portion presented initially a mucosal projection toward the lumen, bending on its own axis, and increased numbers of projections towards the isthmic portion, where the projections become longer more numerous. The endosalpinx becomes more tortuous, the lumen diameter increases and the mucosal projections become more bulky in the ampullary portion, with the projections less present on the antimesenteric side. The infundibular portion is marked with the organized and predictable endosalpinx, the abdominal ostium is cleared demonstrated, with the reduction of the endosalpinx volume. The fimbria demonstrated a small relation between fringes and intratubal endosalpinx.

Conclusions

Microscopic anatomy of different segments of the human FT mucosa can be analyzed and reconstructed in 3D with histological correlation using micro-CT.

Cerebrospinal fluid (CSF) is a dynamic compartment of the brain, constantly circulating through the ventricles and subarachnoid space. In recent years knowledge about CSF has expended due to numerous applications of phase-

contrast magnetic resonance imaging (PC-MRI) in CSF flow evaluation, leading to the revision of former theories and new concepts about pathophysiology of CSF disorders, which are caused either by alterations in CSF production, absorption, or its hydrodynamics.

Although alternative non-invasive techniques have emerged in recent years, PC-MRI is still a fundamental sequence that provides both qualitative and quantitative CSF assessment. PC-MRI is widely used to evaluate CSF hydrodyna­mics in normal pressure hydrocephalus (NPH), Chiari type I malformations (CMI), syringomyelia, and after neurosurgical procedures. In NPH precisely performed PC-MRI provides reliable clinical information useful for differential diagnosis and selection of patients benefiting from surgical operation. Patients with CMI show abnormalities in CSF dynamics within the subarachnoid space, which are pronounced even further if syringomyelia coexists. Another indication for PC-MRI may be assessment of post-surgical CSF flow normalisation.

The aim of this review is to highlight the significance of CSF as a multifunctional entity, to outline both the physical and technical background of PC-MRI, and to state current applications of this technique, not only in the diagnosis of central nervous system disorders, but also in the further clinical monitoring and prognosis after treatment.

Abstract. To investigate the characteristic of atmospheric brown carbon (BrC) in the semi-arid region of East Asia, PM2.5 and size-resolved particles in the urban atmosphere of Xi'an, inland China during the winter and summer of 2017 were collected and analyzed for optical properties and chemical compositions. Methanol extracts (MeOH-extracts) were more light-absorbing than water extracts (H2O- extracts) in the optical wavelength of 300–600 nm, and well correlated with nitrophenols, polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (R2 > 0.6). The light absorptions (absλ=365nm) of H2O- extracts and MeOH-extracts in winter were 28 ± 16 M/m and 49 ± 32 M/m, respectively, which are about 10 times higher than those in summer, mainly due to the enhanced emissions from biomass burning for house heating. Water extracted BrC predominately occurred in the fine mode (

Abstract. Climate models are in need of improved constraints for water vapor transport in the atmosphere and tritium can serve as a powerful tracer in the hydrological cycle. Although general principles of tritium distribution and transfer processes within and between the various hydrological compartments are known, variation on short timescales and aspects of altitude dependence are still under debate. To address questions for tritium sources, sinks and transfer processes, sampling of individual precipitation events in Corte on the island of Corsica in the Mediterranean Sea was performed between April 2017 and April 2018. Tritium concentrations of 46 event samples were compared to their moisture origin and corresponding air mass history. Air mass back-trajectories were generated from the novel high-resolution ERA 5 data set of the ECMWF (European Centre for Medium-Range Weather Forecasts). Geographical source regions of similar tritium concentrations were predefined using generally known tritium distribution patterns, such as a continental effect, and from data records derived at long-term measurement stations of tritium in precipitation across the working area. Our model-derived source region tritium concentrations agreed well with annual mean station values. Moisture that originated from continental Europe and the Atlantic Ocean was most distinct regarding tritium concentrations with values up to 8.8 TU and near 0 TU, respectively. Seasonality of tritium values ranged from 1.6 TU in January to 10.1 TU in May and exhibited well-known elevated concentrations in spring and early summer due to increased stratosphere-troposphere exchange. However, this pattern was interrupted by extreme events. The average altitude of trajectories correlated with tritium concentrations in precipitation, especially in spring and early summer and if outlier values of extreme tritium concentrations were excluded. However, in combination with the trajectory information, these outlier values proved to be valuable for the understanding of tritium movement in the atmosphere. Our work shows how event-based tritium research can advance the understanding of its distribution in the atmosphere.
