Helping learners with dyslexia read in English
Authors: Troeva Blagovesta
Published: April 2019

Dyslexia is a specific learning difficulty which resists conventional teaching methods. The phonological deficit hypothesis of dyslexia determines the present day focus on phonics targeting the primary area of difficulties experienced by learners with dyslexia – decoding. Phonological instruction, however, needs to be accompanied by the development of comprehension skills and presented within a rich language environment. Verbal memory and processing difficulties, typically associated with dyslexia, as well as other frequently co-occurring disorders require the adoption of a number of additional strategies for the teaching of reading to learners with dyslexia. The paper identifies a number of them: multi-sensory approaches, systematic (structured, cumulative and sequential) instruction, over-learning, reinforcement and metacognition. It recognizes the need of time, task and materials differentiation. The choice of particular teaching methods should take into account both the learner’s weaknesses and strengths. Such individually adapted teaching makes the successful inclusion of learners with dyslexia possible in the mainstream classroom.

Targeted Double Negative Properties in Silver/Silica Random Metamaterials by Precise Control of Microstructures
Authors: Xie Peitao , Zhang Zidong , Wang Zhongyang , Sun Kai , Fan Runhua
Published: April 2019

The mechanism of negative permittivity/permeability is still unclear in the random metamaterials, where the precise control of microstructure and electromagnetic properties is also a challenge due to its random characteristic. Here silver was introduced into porous SiO
2
microsphere matrix by a self-assemble and template method to construct the random metamaterials. The distribution of silver was restricted among the interstices of SiO
2
microspheres, which lead to the precise regulation of electrical percolation (from hoping to Drude-type conductivity) with increasing silver content. Negative permittivity came from the plasma-like behavior of silver network, and its value and frequency dispersion were further adjusted by Lorentz-type dielectric response. During this process, the frequency of epsilon-near-zero (ENZ) could be adjusted accordingly. Negative permeability was well explained by the magnetic response of eddy current in silver micronetwork. The calculation results indicated that negative permeability has a linear relation with

, showing a relaxation-type spectrum, different from the “magnetic plasma” of periodic metamaterials. Electromagnetic simulations demonstrated that negative permittivity materials and ENZ materials, with the advantage of enhanced absorption (40dB) and intelligent frequency selection even in a thin thickness (0.1 mm), could have potentials for electromagnetic attenuation and shielding. This work provides a clear physical image for the theoretical explanation of negative permittivity and negative permeability in random metamaterials, as well as a novel strategy to precisely control the microstructure of random metamaterials.

In ihrer neuesten Publikation befasst sich die ausgewiesene Wortbildungsexpertin Elke Donalies mit Fällen wie Wetterbeobachter, Dickhäuter, Vergissmeinnicht, zartfühlend und wieviel, deren linguistische Erfassung nach wie vor Probleme bereitet. Grund dafür dürfte zum einen sein, dass die Worthaftigkeit der untersuchten Einheiten vielfach fraglich ist (z. B. zart fühlend als syntaktische Fügung vs. zartfühlend als Wort bzw. Wortbildungsprodukt). Zum anderen ist die Analyse der Einheiten – bei Zuordnung zum Bereich Wortbildung – schwierig und im Resultat entsprechend vielfältig (z. B. Dickhäuter als Derivation, Zusammenbildung oder synthetic compound (vgl. S. 114)). Donalies hat sich also mit der Wahl derartiger "linguistischer Problemmacher" viel vorgenommen und insgesamt drei Jahre Projektzeit im Rahmen ihrer IDS-Tätigkeit dafür aufgewendet (Januar 2015–Januar 2018).

THE INFLUENCE OF FINE FRACTIONS CONTENT IN NON-COHESIVE SOILS ON THEIR COMPACTIBILITY AND THE CBR VALUE
Authors: Bąk Aleksandra , Chmielewski Ryszard
Published: April 2019

The bearing capacity of subsoils is particularly important due to the intensive development of road and airfield pavements. Subgrade is classified due to frost susceptibility as non-frost-susceptible, low-frost-susceptible or frost-susceptible. Presented research included laboratory tests of low-frost-susceptible soils with limited potential for direct use. The main objective of this paper was focused on the study of changes of compactibility parameters and the CBR (Californian Bearing Ratio) values of silty sand (Pπ). For this purpose, seventeen soil samples with various fine fractions content (of 1.6% to 24.2%), were composed. Laboratory tests, based on soaked soil samples, encompassed the Proctor Compaction test and the CBR test. Additionally, measurements of moisture content in soaked soil samples before and after the penetration test and the displacement of annular surcharge rings while penetration test, were performed. Obtained results allowed for conclusions that penetration curves diverge from the standard curve locally, therefore direct reading of the CBR values from the penetration curves may lead to its significant overstatement. There was also noticed the dependence between the water flow in the soil and the fine fraction content. The research recognized the need for pressure measurement in soil samples during the penetration test.
Persistent Quasi-periodic Pulsations during a Large X-class Solar Flare
Authors: Hayes Laura A. , Gallagher Peter T. , Dennis Brian R. , Ireland Jack , Inglis Andrew , Morosan Diana E.
Published: April 2019

Solar flares often display pulsating and oscillatory signatures in the emission, known as quasi-periodic pulsations (QPP). QPP are typically identified during the impulsive phase of flares, yet in some cases, their presence is detected late into the decay phase. Here, we report extensive fine structure QPP that are detected throughout the large X8.2 flare from 2017 September 10. Following the analysis of the thermal pulsations observed in the Geostationary Operational Environmental Satellite/X-ray sensor and the 131 Å channel of Solar Dynamics Observatory/Atmospheric Imaging Assembly, we find a pulsation period of ∼65 s during the impulsive phase followed by lower amplitude QPP with a period of ∼150 s in the decay phase, up to three hours after the peak of the flare. We find that during the time of the impulsive QPP, the soft X-ray source observed with the Reuven Ramaty High Energy Solar Spectroscopic Imager rapidly rises at a velocity of approximately 17 km s−1 following the plasmoid/coronal mass ejection eruption. We interpret these QPP in terms of a manifestation of the reconnection dynamics in the eruptive event. During the long-duration decay phase lasting several hours, extended downward contractions of collapsing loops/plasmoids that reach the top of the flare arcade are observed in EUV. We note that the existence of persistent QPP into the decay phase of this flare are most likely related to these features. The QPP during this phase are discussed in terms of magnetohydrodynamic wave modes triggered in the post-flaring loops.
IDP-like Asteroids Formed Later than 5 Myr After Ca–Al-rich Inclusions
Authors: Neveu Marc , Vernazza Pierre
Published: April 2019

The parent bodies of ordinary chondrites, carbonaceous CM chondrites, and interplanetary dust particles (IDPs) represent most of the mass of the solar system’s small (D ≤ 250 km) bodies. The times of formation of the ordinary and carbonaceous CM chondrite parent bodies have previously been pinpointed, respectively, to ≈2 and 3–4 million years after calcium–aluminum-rich inclusions (CAIs). However, the timing of the formation of IDP parent bodies such as P- and D-type main-belt asteroids and Jupiter Trojans has not been tightly constrained. Here, we show that they formed later than 5–6 million years after CAIs. We use models of their thermal and structural evolution to show that their anhydrous surface composition would otherwise have been lost due to melting and ice-rock differentiation driven by heating from the short-lived radionuclide 26Al. This suggests that IDP-like volatile-rich small bodies may have formed after the gas of the protoplanetary disk dissipated and thus later than the massive cores of the giant planets. It also confirms an intuitive increase in formation times with increased heliocentric distance, and suggests that there may have been a gap in time between the formation of carbonaceous chondrite (chondrule-rich) and IDP (chondrule-poor) parent bodies.
A Spectroscopic Analysis of the California-Kepler Survey Sample. I. Stellar Parameters, Planetary Radii, and a Slope in the Radius Gap
Authors: Martinez Cintia F. , Cunha Katia , Ghezzi Luan , Smith Verne V.
Published: April 2019

We present results from a quantitative spectroscopic analysis conducted on archival Keck/HIRES high-resolution spectra from the California-Kepler Survey (CKS) sample of transiting planetary host stars identified from the Kepler mission. The spectroscopic analysis was based on a carefully selected set of Fe i and Fe ii lines, resulting in precise values for the stellar parameters of effective temperature (T
eff) and surface gravity (log g). Combining the stellar parameters with Gaia DR2 parallaxes and precise distances, we derived both stellar and planetary radii for our sample, with a median internal uncertainty of 2.8% in the stellar radii and 3.7% in the planetary radii. An investigation into the distribution of planetary radii confirmed the bimodal nature of this distribution for the small-radius planets found in previous studies, with peaks at ∼1.47 ± 0.05 and ∼2.72 ± 0.10 R
⊕ with a gap at ∼1.9 R
⊕. Previous studies that modeled planetary formation that is dominated by photoevaporation predicted this bimodal radii distribution and the presence of a radius gap, or photoevaporation valley. Our results are in overall agreement with these models, as well as core powered mass-loss models. The high internal precision achieved here in the derived planetary radii clearly reveal the presence of a slope in the photoevaporation valley for the CKS sample, indicating that the position of the radius gap decreases with orbital period; this decrease was fit by a power law of the form R
pl ∝ P
−0.11, which is consistent with both photoevaporation and core powered mass-loss models of planet formation, with Earth-like core compositions.

Authors: Saare Murtaja Ali , Hussain Azham , Seng Yue Wong
Published: April 2019

Aging is the biological, psychological, or social change that occur with the passage of time which leads to functional impairment, and eventually chronic diseases. The number of people living older is rapidly increasing, and there is a natural decline in physical activity. The reduced mobility affects their daily life activities making them dependent on others for health. Therefore, mobile technologies such as m-health applications provide potential for enhanced health care among older adults. The present study highlights the factors that affect the adoption of smartphone applications, and potential factors such as mobile peer support can facilitate older adults to adopt latest technologies. However, previous studies have remained unsuccessful in explaining the moderating role of mobile peer support. Therefore, this paper aims to provide an insight with potential solution to the challenges of aging life, hence, enhancing their quality of life. This paper is only a conceptual explanation, which aims to identify the possible factors that influence their smartphone adoption using a systematic literature review on relevant peer-reviewed papers. It is expected that this work will lead towards the empirical findings on the explanation of the interplay of the peer support to address the relationship of assistive mobile health applications and quality of life. This paper provides directions for future studies in improving the quality of life of older adults by using technology.
Analysis and Ideas for Improved Routing in MANET
Authors: Kumar Josh , Kathirvel A.
Published: April 2019

Mobile Ad hoc NETwork is a collection of mobile nodes connected with each other without any centralized infrastructure support. In MANET, every node acts as a router, thereby forwards the packet to other nodes through the best route possible. The cooperation of all other nodes is very essential for a node to transfer data to its desired destination. Throughput is a major factor that determines the health of any network including MANET and there can be many reasons that can disrupt the throughput. In this paper we deal with two prime reasons that may reduce the throughput in a MANET. The first reason is that, if a node behaves selfishly and utilizes the path only for forwarding its own packet, then the packets from other nodes will be dropped and the throughput will gradually get reduced. The second reason for reduction in throughput is the phenomenon called fading, which causes signal attenuation. This phenomenon creates path loss temporarily, during which the packet loss increases and the throughput takes a major hit. Removing such nodes from the network on the basis of doubt about its packet forwarding nature and ability will eventually weaken the network strength. Neglecting the original best route will also reduce the quality of the network. Both the cases of selfishness and fading can be normalized by switching over to an alternate path and coming back to the same route after a short period of time. Thereby the quality as well as the quantity of nodes involved in the network can be maintained. In this paper we have also introduced an innovation called helper nodes which will also help in the formation of alternate path and will very well neutralize the ill effects caused due to selfishness and fading.

Authors: Sfeir Elizabeth Kassab
Published: April 2019

Organizations must continuously monitor their processes. They should make significant changes to retain talent and improve productivity. One way to recognize the need to achieve change is through improving their organizational culture. This article details the investigation of a phenomenon of organizational culture in the Middle East. Wasta is a Middle Eastern system of preferment operating in many institutions in the region affecting employee engagement, advancement, and influence within an organization. Interviews, observations and social network analysis were employed to investigate the degree to which this phenomenon occurs in four universities in Lebanon and its negative effects on employee relationships. The data was input into NVivo to obtain statistical information to support the hypothesis of wasta's negative role. The research process culminated in the development of the wasta organizational culture model (WOC), highlights the impact of wasta on employee relationships supporting further research and collaborative initiatives to improve HR practices in the Middle East.

Exercising these advantages come with a plethora of security risks that need to be addressed. The security issues in cloud are complex due to the nature of implementation and regulations that govern them. In this article, we examine existing research on cloud risk and the various frameworks to manage risk. The objective is to map the risk with the audit control and technology that will help in mitigating the risk. We analysed the various cloud security solutions and came up with a list that best help in the effective management of the cloud risk and security issues.
Game-Theoretic Analysis of Pricing Models in a Dyadic Supply Chain With Fairness Concerns
Authors: Sharma Abhishek
Published: April 2019

The existing studies on fairness in channel coordination assume markets as the group of oligopolies in which a few firms dominate, scant evidence has been provided where fairness concerns are investigated for a market scenario where all firms share equal dominance. This article considers a dyadic supply chain composed of one fair-minded manufacturer and one fair-minded retailer and investigate their pricing decisions under two different non-cooperative game-theoretic frameworks: manufacturer-led Stackelberg game and Vertical Nash game and provide a comparative analysis. The results show that the prices of the Stackelberg game model are always higher than that of the corresponding prices of the Vertical Nash game. We also find that the prices gap between the two models decreases with the retailer's fairness concern, and is uncertain with respect to manufacturer's fairness. In addition, the manufacturer's (retailer's) profit in the Stackelberg game is decreasing (increasing) in its own fairness and is uncertain in the Vertical Nash game. Furthermore, findings are illustrated through a numerical example.

Published: April 2019

Bridges are aging and deteriorating. Thus, the development of Bridge Management Systems (BMSs) became imperative nowadays. Condition assessment is one of the most critical and vital components of BMSs. Ground Penetrating Radar (GPR) is one of the non-destructive techniques (NDTs) that are used to evaluate the condition of bridge decks which are subjected to the rebar corrosion. The objective of the proposed method is to develop standardized amplitude scale for bridge decks based on a hybrid optimization-decision making model. Shuffled frog leaping algorithm is employed to compute the optimum thresholds. Then, polynomial regression and artificial neural network models are designed to predict the prioritizing index based on a set of multi-criteria decision-making methods. The weibull distribution is utilized to capture the stochastic nature of deterioration of concrete bridge decks. Lastly, a case study is presented to demonstrate the capabilities of the proposed method.

RDF Keyword Search by Query Computation
Authors: Ma Zongmin , Lin Xiaoqing , Yan Li , Zhao Zhen
Published: April 2019

Keyword searches based on the keywords-to-SPARQL translation is attracting more attention because of a growing number of excellent SPARQL search engines. Current approaches for keyword search based on the keywords-to-SPARQL translation suffer from returning incomplete answers or wrong answers due to a lack of underlying schema information. To overcome these difficulties, in this article, we propose a new keyword search paradigm by translating keyword queries into SPARQL queries for exploring RDF data. An inter-entity relationship summary with complete schema information is distilled from the RDF data graph for composing SPARQL queries. To avoid potentially wasteful summary graph expansion, we develop a new search prioritization scheme by combining the degree of a vertex with the distance from the original keyword element. Starting from the ordered priority list that is built in advance, we apply the forward path index to faster find the top-k subgraphs, which are relevant to the conjunction of the entering keywords. The experimental results show that our approach is efficient and scalable.

Published: April 2019

The present study focuses on the new application of geopolymer ceramic composites as substrate cultures, resulting from the geopolymer properties being similar to those of the substrate cultures such as water absorption, non-biodegradation, high porosity, and light weight. The geopolymers were synthesized from ceramic wastes and metakaolin using the geopolymerization method via a reaction with an alkaline solution. To compare usefulness for substrate culture applications, the porosity of different samples was varied. Moreover, the properties of all samples were investigated using an additional method of verification. The chemical characteristics were evaluated by FT-IR spectroscopy. The microstructures, pore sizes, pore distributions and surface areas of the pores were examined with image analysis using scanning electron microscopy (SEM). The densities were determined using the Archimedes’ method. The porosity and water absorption were also measured. The mechanical properties were investigated by using a compression testing machine.

Authors: Khongwong Wasana , Keawprak Nittaya , Somwongsa Phunthinee , Tattaporn Duriyoung , Ngernchuklin Piyalak
Published: April 2019

The paper is focused on the influence of alternative fillers on rubber compounds properties. Three different types of powder fillers, drinking water treatment sludge (DWTS), perlite and calcium carbonate, were mixed into rubber compound mixtures. The mixtures were composed of STR20, EPDM, zinc oxide, steric acid, paraffin wax, 2-mercaptobenzothiazole (MBT), sulphur, Wingstay L, and filler. The mixtures were mixed in a Kneader type mixer at temperature of 70°C and then continuously mixed using a two-roll mill at temperature of 70°C. The relationships between type and the amount of filler versus properties of rubber compounds were demonstrated. The results showed that tensile and elongation at break of rubber compounds gradually decreased with increasing the amount of filler. Rubber compounds filled with small particle size filler possessed higher tensile strength and elongation at break than those filled with large particle size filler. Values of DIN abrasion loss of rubber compounds prepared under proper mixing condition were not more than 300 mm3. Under appropriate condition, the rubber compounds with DWTS, perlite and calcium carbonate provided sufficiently high shore A hardness (not less than 50 Shore A hardness). Finally, alternative fillers such as DWTS and perlite were expected to replace calcium carbonate in normal formula.

Authors: Jindasuwan Sunisa , Supothina Sitthisuntorn
Published: April 2019

The separation of oil from water is significance for environmental de-pollution application. To obtain selectivity of liquid, filter papers were coated to bear highly hydrophobic and oleophilic functionality that can allow only oils to pass through them. The coating solutions were prepared by mixing poly(methylhydro siloxane, PMHS) and fumed silica at various proportions. To determine an optimum coating condition, properties of the treated filter papers were investigated by measuring water contact angle and surface free energy, examining surface morphology and testing for selective removal of diesel oil from water. The optimum coating solution was at the PMHS:fumed silica weight ratio of 1.25:1.00. The treated filter paper exhibited high hydrophobicity with water contact angle of 142.80 ± 0.36 degrees and surface free energy of 0.78 mJ/m2. In addition, it exhibited high selective removal of diesel oil from water with oil absorption capacity of 2.3 g/g.

Published: April 2019

Combustion of diesel fuel containing sulfur compounds emits SOx into atmosphere causing acid rain and respiratory illness in human. Dibenzothiophene (DBT) is one of the most difficult sulfur compounds in diesel to be removed by hydrodesulfurization (HDS). To produce ultra-low sulfur diesel (<15 ppmw-S), severe operating condition is required. As a result, production cost is increase. In this work, we investigated an alternative method for sulfur removal called Light-enhanced Adsorptive Desulfurization or L-ADS using supported TiO2-ZrO2. The TiO2-ZrO2 was loaded on commercial γ-Al2O3, fumed silica (FS), silica gel (SG) and zeolite (Z30) by wet-impregnation method. Impact of these supports on DBT removal were focused. Characteristic of the supported TiO2-ZrO2 was analyzed by N2 adsorption-desorption, scanning electron microscopy equipped with energy dispersive spectroscopy (SEM-EDS), and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS). The presence of TiO2-ZrO2 greatly enhanced DBT removal compared to TiO2 and ZrO2. SG promoted DBT removal by facilitating the adsorption of dibenzothiophene sulfone (DBTO2), a product of DBT photocatalytic oxidation. Using TiO2-ZrO2/SG, 86% of sulfur was removed from 50 ppmw-S DBT/C16 within 4 h.

The organic dye is one of the carcinogenic and toxic substrates that are used as the colorant in industries. Therefore, we have to develop the efficient technique to remove the dye in wastewater. This research aimed to develop the photoelectrocatalytic (PEC) cell with the high efficiency, which offered a simple method to remove dye from the wastewater. The ZnO photoanode electrode was considered for developing to enhance the efficiency of PEC cell for dye degradation. The ZnO electrode was fabricated by cyclic voltammetry method and then was compared the oxidation efficiency to ZnO electrode from dip coating. The film thickness of ZnO was controlled by the number of scan for a cyclic voltammetric method and the deposition time for the dip coating method. The effects of scan rate, the number of scan and calcination temperature were optimized to obtain the highest oxidation efficiency. Absorption properties, photoelectrocatalytic activity and electrochemical impedance spectroscopy (EIS) were measured to confirm the characteristic of the two fabricated electrodes. The results showed that ZnO electrode fabricated by cyclic voltammetry presented higher photoelectrocatalytic activity for water oxidation than that from dip coating. Thus, in this research was development ZnO electrode by cyclic voltammetry to degrade organic dye using the photoelectrocatalytic technique. The efficiency of dye degradation was evaluated by the decreasing absorption of methylene blue dye (5 mg/L) as a function of time. It was found that the photoelectrocatalytic dye degradation efficiency with ultrasonic-assisted was enhanced up to two times with 71% degradation in 1 hour. Therefore, we concluded that the developed ZnO electrode by cyclic voltammetry demonstrated a high photoelectrocatalytic performance with ultrasonic-assisted degradation of organic dyes.

Synthetic polymers are widely used in biomedical applications due to their advantages compared to other materials including low cost and ease of processability, good corrosion resistance and high properties to weight ratio. Among several polymeric biomaterials, polyethylene is a biocompatible polymer which has a long history of being utilized in many biomedical applications ranging from simple components to advanced implants. Although dense polyethylene is known to be a bioinert material which does not interact with host tissue, polyethylene in its appropriate porous form has been shown to be able to integrate well with surrounding host tissues and could widen its uses as bioactive implants. Porous polyethylene structure which was fabricated by three dimensional printing (3DP) is demonstrated. Its manufacturing technique, properties and clinical applications as tissue integrated implants which permitted soft or hard tissue ingrowth in tissue regeneration and replacement is discussed.

Malignancy increases sepsis incidence 10-fold and elevates sepsis-associated mortality. Advances in treatment have improved survival of cancer patients shortly after sepsis, but there is a paucity of information on how sepsis impacts cancer growth, development, and prognosis. To test this, cecal ligation and puncture surgery was performed on B16 melanoma-bearing mice to show that sepsis has detrimental effects in hosts with advanced tumors, leading to increased mortality. Surprisingly, mice experiencing cecal ligation and puncture–induced sepsis earlier during tumor development exhibited CD8 T cell–dependent attenuation of tumor growth. Sepsis-resistant CD8 tumor-infiltrating T cells showed increased in vivo activation, effector IFN-γ cytokine production, proliferation, and expression of activation/inhibitory PD-1/LAG-3 receptors because of a sepsis-induced liberation of tumor Ags. Sepsis-reinvigorated CD8 tumor-infiltrating T cells were also amenable to (anti–PD-L1/LAG-3) checkpoint blockade therapy, further prolonging cancer-associated survival in sepsis survivors. Thus, sepsis has the capacity to improve tumor-specific CD8 T cell responses, leading to better cancer prognosis and increased survival.

Abstract. The acid deposition has been considered to be a severe environmental issue in China. The pH, electrical conductivity (EC), and the concentrations of the water soluble ions (NO3−, Cl−, Ca2+, K+, F−, NH4+, Mg2+, SO42−, and Na+) in the precipitation samples collected from the 320 cities during 2011–2016 across the whole China were measured. The mean concentrations of F−, NO3− and SO42− were in the order of winter (6.10, 19.44 and 45.74 μeq/L) > spring (3.45, 13.83, and 42.61 μeq/L) > autumn (2.67, 9.73, and 28.85 μeq/L) > summer (2.04, 7.66, and 19.26 μeq/L). The secondary ions (SO42−, NO3− and NH4+), and F− peaked in Yangtze River Delta (YRD) and Sichuan basin (SB). The crustal ions (i.e., Ca2+, Mg2+), Na+, and Cl− showed the highest concentrations in the semi-arid regions and the coastal cities, respectively. The statistical methods confirmed that the mean anthropogenic contribution ratios to SO42−, F−, NO3−, and NH4+ at a national scale were 46.12 %, 71.02 %, 79.10 %, and 82.40 %, respectively. However, Mg2+ (70.51 %), K+ (77.44 %), and Ca2+ (82.17 %) were mostly originated from the crustal source. Both Na+ (70.54 %) and Cl− (60.42 %) were closely linked to the sea-salt aerosols. On the basis of the stepwise regression (SR) analysis, it was proposed that most of the secondary ions and F− were closely related to gross industrial production (GIP), total energy consumption (TEC), vehicle ownership, and N fertilizer use, but the crustal ions (Ca2+ and K+) were mainly controlled by the dust events. The influence of dust days, air temperature, and wind speed on ions increased from Southeast China (SEC) to Central China, and then to Northwest China (NWC), whereas the influence of socioeconomic factors on acid ions (SO42− and NO3−) displayed the higher value in East China.

Abstract. Vertical profiles of the particle backscattering coefficient
at 355, 532 and 1064 nm measured by the University of Basilicata Raman
lidar system (BASIL) have been compared with simulated particle backscatter profiles obtained through a Mie
scattering code based on the use of simultaneous and almost co-located
profiles provided by an airborne optical particle counter. Measurements
were carried out during dedicated flights of the French research aircraft
ATR42 in the framework of the European Facility for Airborne Research (EUFAR)
project “WaLiTemp”, as part of the Hydrological Cycle in the Mediterranean
Experiment – Special Observation Period 1 (HyMeX-SOP1). Results from two
selected case studies are reported and discussed in the paper, and a dedicated analysis approach is illustrated and applied to the
dataset. Results reveal a good agreement between measured and simulated
multi-wavelength particle backscattering profiles. Specifically, simulated
and measured particle backscattering profiles at 355 and 532 nm for the second case study are found to
deviate less than 15 % (mean value =5.9 %) and 50 % (mean
value =25.9 %), respectively, when considering the presence of a
continental–urban aerosol component, while slightly larger deviation values are found for the first study. The reported good agreement between
measured and simulated multi-wavelength particle backscatter profiles
testifies to the ability of multi-wavelength Raman lidar systems to infer
aerosol types at different altitudes.
