Published: June 2021

Flood control risk is one of the main risks affecting the safe operation of large-scale water transfer projects. Systematically identifying the flood control risk in the project and carrying out risk classification and hierarchical management are problems for project managers. Based on the theory of system and risk assessment, this paper starts with the various risk sources and risk events involved in the whole process of the flood disaster chain, the risk of flood disaster factors, the exposure of the disaster-bearing body, and the vulnerability of the disaster-originating environment are combined. Then, we systematically and comprehensively identify the flood control risks of a large-scale water transfer project, which are divided into four types of risk elements: rainfall–runoff; confluence and flow capacity; the geological characteristics of canal section; economic and social layouts. Specific risk factors are identified for each type of risk element, and a flood control risk evaluation index system for a water transfer project is proposed. According to the framework of the analytic hierarchy process (AHP), a quantitative assessment of comprehensive flood control for water transfer projects is carried out. Taking the middle route of the South-to-North Water Transfer Project in China as an example, this paper evaluates the integrated flood control risks of 39 engineering units, identifies six units with higher risk levels, analyzes the causes, and suggests engineering and non-engineering countermeasures to prevent and reduce the occurrence of risk accidents. This method is not only used for comprehensive flood control risk assessment and risk management in the operation and management stage of the large-scale inter-basin water transfer project, but also has a reference value in considering the optimal layout of the project water transmission line from the perspective of flood control in the planning and design stage.
Accurate Open Channel Flowrate Estimation Using 2D RANS Modelization and ADCP Measurements
Authors: Figuérez Juan Alfonso , González Javier , Galán Álvaro
Published: June 2021

Boat-mounted Acoustic Doppler Current Profilers (ADCP) are commonly used to measure the streamwise velocity distribution and discharge in rivers and open channels. Generally, the method used to integrate the measurements is the velocity-area method, which consists of a discrete integration of flow velocity over the whole cross-section. The discrete integration is accomplished independently in the vertical and transversal direction without assessing the hydraulic coherence between both dimensions. To address these limitations, a new alternative method for estimating the discharge and its associated uncertainty is here proposed. The new approach uses a validated 2D RANS hydraulic model to numerically compute the streamwise velocity distribution. The hydraulic model is fitted using state estimation (SE) techniques to accurately reproduce the measurement field and hydraulic behaviour of the free-surface stream. The performance of the hydraulic model has been validated with measurements on two different trapezoidal cross-sections in a real channel, even with asymmetric velocity distribution. The proposed method allows extrapolation of measurement information to other points where there are no measurements with a solid and consistent hydraulic basis. The 2D-hydraulic velocity model (2D-HVM) approach discharge values have been proven more accurate than the ones obtained using velocity-area method, thank to the enhanced use of the measurements in addition to the hydraulic behaviour represented by the 2D RANS model.
3D-CNN-Based Sky Image Feature Extraction for Short-Term Global Horizontal Irradiance Forecasting
Authors: Yang Hao , Wang Long , Huang Chao , Luo Xiong
Published: June 2021

The instability and variability of solar irradiance induces great challenges for the management of photovoltaic water pumping systems. Accurate global horizontal irradiance (GHI) forecasting is a promising technique to solve this problem. To improve short-term GHI forecasting accuracy, ground-based sky image is valuable due to its correlation with solar generation. In previous studies, great efforts have been made to extract numerical features from sky image for data-driven solar irradiance forecasting methods, e.g., based on pixel-value color information, and based on the cloud motion detection method. In this work, we propose a novel feature extracting method for GHI forecasting that a three-dimensional (3D) convolutional neural network (CNN) is developed to extract features from sky images with efficient training strategies. Popular machine learning algorithms are introduced as GHI forecasting models and corresponding forecasting accuracy is fully explored with different input features on a large dataset. The numerical experiment illustrates that the minimum average root mean square error (RMSE) of 62 W/m2 is achieved by the proposed method with 15.2% improvement in Skill score against baseline forecasting method.
Grading Evaluation of the Structural Connectivity of River System Networks Based on Ecological Functions, and a Case Study of the Baiyangdian Wetland, China
Authors: Tian Kai , Yin Xin-an , Bai Jie , Yang Wei , Zhao Yan-wei
Published: June 2021

River system network (RSN) connectivity is important to maintain the environmental and ecological functions of wetlands. Quantitative evaluation of connectivity can provide crucial support for efforts to improve wetland connectivity and to restore and protect wetland ecosystems. Most existing evaluation methods uniformly generalise RSN to form an undifferentiated RSN of edges and nodes that is taken as a whole to evaluate the connectivity. However, actual RSNs comprise rivers, canals, ditches, lakes, and ponds, which differ substantially in their structures, morphologies, and attributes. The mix of RSN elements therefore defines grades that give RSNs distinctive characteristics. Moreover, RSNs with different grades perform different ranges of environmental and ecological functions. The existing evaluation methods, which have some limitations, do not account for these characteristics. To account for these differences, we examined the grade characteristics and their impact on environmental and ecological functions. We established a grading system of RSN elements and a grading method of RSN, and constructed the structural connectivity evaluation indicator system for RSNs at different grades. On this basis, we propose a method for grading evaluation of RSN connectivity. We used China’s Baiyangdian Wetland to demonstrate the use of the system and validate the results. The proposed method provided an objective and accurate evaluation of RSN connectivity and clarified the differences in connectivity among RSNs with different grades, thereby providing improved guidance for the development and maintenance of the environmental and ecological functions of RSNs.

Published: June 2021

The production of electric energy from rivers by using mini, as well as micro hydroelectric power plants, is a very promising solution, especially in rural and isolated areas. Numerous waterways in Croatia and their hydrological and hydrogeological diversity present an opportunity, but also a challenge, for the construction of hydroelectric power plants. Due to the complexity of the water courses’ hydrology, as well as hydrogeological characteristics, it is very hard to determine an appropriate flow pattern (amount), which will be used as an input value for the sizing of hydroelectric power plants. Such analysis will be provided for real case studies in Croatia with special regard to present geological media—media with intergranular porosity (Bednja River), karst media (Gornja Dobra River), and flysch media (Mirna River). Considering different geological media increases the possibility of using the presented methodology on other locations in Croatia, as well in the world. It has been shown that the analyzed rivers definitely have potential for electric energy production, regarding the potential and kinetic river energy. The presented analysis is scientifically original, but also shows the procedure for the determination of the hydro-energy potential of the rivers, as well as for the sizing on the hydropower plants. Hydrology and hydrogeology analyses rounds out the usual hydro-energy analysis, which is in most cases based on basic statistical parameter analysis.

Authors: Curtean-Bănăduc Angela , Burcea Alexandru , Mihuţ Claudia-Maria , Bănăduc Doru
Published: June 2021

Persistent organic pollutants (POPs) have been at the forefront of environmental contamination research even before their ban in 2001 at the Stockholm Convention. Their relation to different compartments of the environment (biotic and abiotic) has been thoroughly investigated. This article aims to identify whether the benthos could represent a reliable indicator of environmental contamination with POPs and to highlight its potential transfer role between abiotic and upper trophic compartments—benthos feeders. In this regard, we determined that the Ephemeroptera samples have higher concentrations (p < 0.05) of ΣPCB, ΣHCH, and ΣDDT than sediment samples while Trichoptera samples have higher concentrations (p < 0.05) only in the case of ΣPCB and ΣDDT. This, along with the fact that the frequency of detection for POPs is similar between the sample types (sediments, Trichoptera, and Ephemeroptera), makes the benthos samples valuable indicators of contamination with sediment samples working as complementary information about how recent the contamination is.

Authors: Romero-Montoya Hugo , Sánchez-Partida Diana , Martínez-Flores José-Luis , Cano-Olivos Patricia
Published: June 2021

The present study proposes developing a multivariate model that predicts water availability in Mexico through 26 variables related to aquifers, renewable water, demographic characteristics, rivers and basins, dams, and irrigation factors. The information inherent to them was extracted from the platform of the national water system using records from the 13 administrative hydrological regions between 2010 and 2017. The model is based on the multiple linear regression model and the variable selection method. The results show different versions of the model contrasted concerning the statistical assumptions of the multiple regression. Although the findings presented have implications in the development of strategies focused on a better distribution of the vital liquid, in the face of various projected scenarios based on the variables analyzed, it should be noted that the progressive improvement of the model was carried out through the use of techniques such as the transformation of variables, detection, and elimination of outliers. The final result is water availability in the face of various drought conditions explained by a model with 16 relevant variables. Said prediction model is helpful for the generation of drought mitigation strategies.
Developing a Novel Water Quality Prediction Model for a South African Aquaculture Farm
Authors: Eze Elias , Halse Sarah , Ajmal Tahmina
Published: June 2021

Providing an accurate prediction of water quality parameters for improved water quality management is a topical issue in the aquaculture industry. Conventional prediction methods have shown different challenges like a poor generalization, poor prediction accuracy, and high time complexity. Aiming at these challenges, a novel hybrid prediction model with ensemble empirical mode decomposition (EEMD) and deep learning (DL) long-short term memory (LSTM) neural network is proposed in this paper. In this innovative hybrid EEMD-DL-LSTM model, firstly, the integrity of the datasets is enhanced by applying moving average filtering and linear interpolation techniques of water quality parameter datasets pre-treatment. Secondly, the measured real sensor water quality parameters dataset is decomposed with the aid of the EEMD algorithm into disparate IMFs and a corresponding residual item. Thirdly, a multi-feature selection process is applied to make a careful selection of a strongly correlated group of IMFs with the measured real water quality parameter datasets and integrate them as inputs to the DL-LSTM neural network. The presented model is built on water quality sensor data collected from an Abalone farm in South Africa. The performance of the novel hybrid prediction model is validated by comparing the results against the real datasets. To measure the overall accuracy of the novel hybrid prediction model, different statistical indices, namely the Mean Absolute Error (MAE), Mean Square Error (MSE), Root Mean Square Error (RMSE), and Mean Absolute Percentage Error (MAPE), are used.

Seasonal and Decadal Variations of the Variance of the Synoptic and Mesoscale Sea Level Variability in the Baltic Sea
Authors: Medvedev Igor , Medvedeva Alisa
Published: June 2021

The present study examines the seasonal and decadal changes of the variance of the synoptic (periods from 2 days to 30 days) and mesoscale (periods from 2 h to 2 days) sea level oscillations in the Baltic Sea. Long-term hourly sea level records were used at 12 tide gauges located in different parts of the sea. We used spectral analysis to estimate the variance for different time scales. The spectral density of sea level oscillations in the Baltic Sea has maximum values in winter when the cyclonic activity in the atmosphere is more intensive. The maximum variances of synoptic σsyn2  and mesoscale σmes2 sea level oscillations are observed in winter, except for the heads of the Gulf of Finland (Gorny Institute) and Gulf of Riga (Pärnu), where the absolute maximum of σsyn2 is reached in November. The variances σsyn2 and σmes2 from November to February are 2–3 and 5 times higher than in the summer. The values of σsyn2 and σmes2 are characterized by high correlation up to 0.7–0.75 with wind variations and atmospheric indices (NAO, AO, and SCAND) in winter and low correlation in summer. The zonal wind and σmes2 in Gorny Institute are characterized by wide areas of high coherence at periods of 0.7–4 years. At Gedser, σsyn2 decreased by 19%, and at Ratan it increased by 17% over 90 years. The values of σmes2 over 90 years increased by 32% at Klagshamn, 36% at Ratan, and up to 60% at Kungsholmsfort.

Published: June 2021

The most devastating flood event in Kota Bharu was recorded in December 2014, which affected several properties worth millions of dollars and thousands of homes. Damage to physical properties, especially buildings, is identified as a significant contributor to flood disasters in Malaysia. Therefore, it is essential to address physical flood vulnerability by developing an integrated approach for modeling buildings’ flood vulnerability to decrease the flood consequences. This study aims at developing a flood vulnerability assessment approach using an indicator-based model (IBM) for individual buildings in Kota Bahru, Kelantan, Malaysia. An intensive literature review and expert opinions were used to determine suitable indicators that contribute to the physical flood vulnerability of buildings. The indicators were grouped into three components, i.e., flood hazard intensity (I), building characteristics (C), and effect of the surrounding environment (E). The indicators were further refined based on expert opinions and Relative Importance Index (RII) analysis. Based on their contribution to the Malaysia local building flood vulnerability, priority weight is assigned by the experts to each of the selected indicators using the participatory Analytical Hierarchy Process (AHP). A spatial database of buildings in Kota Bharu is developed through field surveys and manually digitizing building footprints from satellite imageries. The identified indicators and their weight are added to each building footprint. The Weighted Linear Combination (WLC) aggregation method combined the weight of indicators into a vulnerability index and maps. The results of a physical flood vulnerability were validated using building damage information obtained through interviews with the community that experienced previous flood in the study area. The result showed that about 98% of the study area’s buildings have either moderate or low vulnerability to flooding. The flood vulnerability map has an overall accuracy of 75.12% and 0.63 kappa statistics. In conclusion, the IBM approach has been used successfully to develop a physical flood vulnerability for buildings in Kota Bharu. The model contributes to support different structural and non-structural approaches in the flood mitigations process.

Published: June 2021

Vitamin B12 (VB12) is applied as the cofactors in various important enzymatic reactions and is involved in gene expression regulation mediated by B12-riboswitch and the VB12-dependent photoreceptor. Rapid detection VB12 concertation in a given environment may provide insights in the evaluation of micronutrient levels and the physiological and ecological performances of organisms under the relevant condition. This study demonstrating an amperometric approach to quantify the VB12 in biological samples without complicated sample pretreatment. The electrochemical oxidation step was conducted with a plain graphenic electrode to convert all nitrogen groups within the VB12 molecules to NO3− at 1.3 V vs. Ag/AgCl for 15 min. VB12 was quantified stoichiometrically according to the oxidized nitrate anions, which were reduced with copper oxide nanocrystal decorated graphenic electrode. Cathodic polarization was conducted with a graphite rod electrode before nitrate reduction to eliminate the potential interferences. Under optimized experimental conditions, the presented approach gave a wide detection linear range of 0.15–7378 nmol L−1 and the detection limit was 0.59 nmol L−1. The results for biological samples were comparable to those of the HPLC method. These results indicated that successively combined anodic and cathodic polarization enhanced the detection sensitivity and efficiency of the electrode towards VB12. The proposed electrode shows potential in terms of efficiency, reliability and accuracy for rapid determination of VB12 in biological samples.

Published: June 2021

The two destination life cycle models proposed by Plog (1974) and Butler (1980) have been recognizing by most of the tourism destination scholars. Questions tend to arise on the possible use of these models to map the entire destination life cycle from the beginning. Therefore, this study aims to discuss the possibility of entire lifespan of tourism destination by using the destination life cycle models from Plog and Butler. This research analyses the strengths and weaknesses of the models revealed from existing studies using critical inputs of the tourism industry. The main difference between the famous models, i.e. Butler and Plog lies in the authors' background and the approach of the different themes. Complexity factors such as multi-market, time boundaries, political agenda, market evolution/ access, mode of transportation, and technological innovation, makes it impossible to map the entire destination life cycle confidently. The ability to innovate reduces the relevancy of life cycle models. Therefore, the DMO needs to deal with the changes associated with increasing the destination's values to avoid stagnation or decline in stages.

Published: June 2021

Large-size organic halide passivation has been considered an efficient approach to enhance the perovskite solar cell (PSC) efficiency and stability. Herein, a facile posttreatment strategy was demonstrated, wherein trifluoromethyl-phenethylamine hydrobromide (CF3-PEABr) is firstly used to passivate the perovskite film surface. The CF3-PEABr surface posttreatment could coordinate with halide dangling bonds that exist at the perovskite crystal surface. Moreover, the surface treatment with CF3-PEABr could efficiently passivate the defects in the perovskite film and suppress the nonradiative carrier recombination. As a result, a high efficiency of 21.3% is obtained, and an increment of 80 mV inVoc(a largeVocof 1.15 V, with a 0.42 V voltage deficit) occurs, compared to the control device. To relieve the hydrophobic nature properties of the -CF3functional group and the dewetting problem of PCBM layer deposition, a surfactant Triton X-100 is used to modify the PCBM layer. Furthermore, the devices with CF3-PEABr posttreatment exhibit better operational, thermal (85°C), and long storage stabilities without any encapsulation.

The main goal of this article is to establish a structure of the knowledge of communication inside of intercultural marriages. For that, two main goals will be pursued. The first one is about the organization of basic knowledge about mixed marriages. This basic knowledge is subdivided into the exogamy, which leads to the focus on problematic fields, for they are common in mentioned marriages. The fields are dependent on factors such as religiosity/religion and the relation towards the family of origin. The second goal is the highlighting of a process, that clarifies the choice of languages inside these partnerships, which in the following is going to underline the impact and influence of each partner’s culture towards the act of communication. The authors are going to apply basic theorems (mainly Hofstede) of intercultural psychology. Communication, hereby, will be spotlighted in the context of marital satisfaction.
Gender and judging in Tunisia and the intersections of penalty and privilege
Authors: Voorhoeve Maaike
Published: June 2021

The international community encourages countries to increase the number of women in the judiciary. This is partly based on the hypothesis that female judges make the bench representative of society. However, the question arises as to which women we are referring to. While the experiences of women are different from men because of their sex, experiences of lower-class women are also different from those from the middle and upper classes, as experiences of women belonging to a minority are different from those belonging to the majority. Using the intersectionality grid of “penalty and privilege” proposed by Patricia Hill Collins (2000), this article aims to look beyond the gender-binary in the study of judges in Muslim contexts by bringing in an intersectional approach, using Tunisia as a case study. Focusing on two female judges functioning under the Tunisian authoritarian regime, this study hopes to show how different women bring different experiences to the bench.
European citizenship as an instrument to protect vulnerability
Authors: Enes Graça
Published: June 2021

The creation of European citizenship by the Maastricht Treaty was not enthusiastically received. The rights it conferred were essentially those already in force in the European Community. The case law of the ECJ gave substance to European citizenship, describing it as “the fundamental status of nationals of the Member States”. The interpretation of the ECJ shaped this new status and its rights, making it an instrument to protect migrant nationals of Member States, especially important for individuals in vulnerable situations: e.g. disabled people, homosexuals, even displaced students, welcoming in the judicial hermeneutic exercise a broad concept of vulnerability (Fineman 2010), whether structural and permanent, or individual or conjunctural; with regard to children, vulnerability justified the extension of protection to parents. The following analysis goes through some of the “leading cases” of Union citizenship, focusing on the protective scope of that status in the context of the concrete situation “sub judice”.

Published: June 2021

Latin America reveals the highest rates of non-reporting of crime worldwide, even more so in countries like Ecuador where non-reporting is recorded in 80% of criminal events. Studies on victims and non-reporting are still scarce and have focused on victimization rates; in addition, there is a theoretical gap on non-reporting from its primary causalities. This study analyzes it from the observation of the socio-demographic profile of the victims and the type of crime perpetrated as influencing factors. Using quantitative research methods, the III Survey of Victimization and Perception of Citizen Security of Cuenca, Ecuador, 2016 was analyzed, which shows a profile of a victim who does not report linked to exclusion, poverty and inequities and a pattern of less reported crimes in thefts, robberies and extortion, factors that must be recognized in order to focus victimological public policy efforts.

Este artigo discute a ideologia e ação política na ascensão de João Havelange. Via de regra, as biografias tradicionais sobre o dirigente brasileiro ressaltam o caráter inovador e distinto da vida de João Havelange. Na contramão desta narrativa, este artigo pretende inserir as ideias de Havelange no próprio contexto em que elas foram difundidas e produzidas. Neste sentido, longe de se constituir um caso atípico e singular, a trajetória de Havelange é observada como uma estratégia metodológica para compreender características mais abrangentes do grupo em que representa – os dirigentes de futebol e a elite política carioca.
Brasil 3 x 1 Uruguai, semifinal da Copa de 70 (um relato-ensaio retrospectivo)
Authors: Assunção Teodoro Rennó
Published: June 2021

Como o título bem indica, este artigo é uma mistura de relato e ensaio interpretativo sobre a partida semifinal da Copa do Mundo de futebol de 1970 entre a seleção brasileira e a uruguaia, cujo resultado foi a vitória do Brasil por 3 a 1. Mas ele é também a tentativa de restituir detalhadamente, por meio de uma partida decisiva e difícil, não somente a maneira de jogar de uma equipe habilidosa e criativa no meio de campo e no ataque (dando destaque a um jogador taticamente importante, mas às vezes menos lembrado do que Pelé, Jairzinho ou Gérson, que é o Tostão, e à sua destreza ímpar nos passes), mas de restituir também o modo como no futebol os momentos ou as situações de uma partida podem mudar repentina e imprevisivelmente, demandando assim dos jogadores (além do preparo físico e da essencial vontade de ganhar) uma atenção à variação dos momentos e às chances únicas e decisivas.

Authors: Kumar Nilabh , Chaudhary Laljee , Jana Debarshi
Published: June 2021

Background:The proximal femoral nail (PFN) used as an intramedullary device for the treatment of fractures.
Objectives: Study was taken to analyse the union of the subtrochanteric fracture, internally xed with PFN.
Materials and Methods: Study was conducted in the Department of Orthopaedics, DMCH, Laheriasarai, Bihar from June 2019 to November
2019. Individuals with acute subtrochanteric femur fractures >18 years were included in the study. The patient was positioned supine on the
fracture table under spinal or epidural or general anesthesia as the condition of the patient permitted. Pre-operatively one dose of antibiotic was
also administered. The fracture was reduced by longitudinal traction on fracture table and the limb was placed in neutral or slight adduction to
facilitate nail insertion through the greater trochanter ; P <0.05 was considered statistically signicant.
Results: At the end of ve months, all except three patients could mobilise independently; statistically there was signicant difference (P<0.05).
Based on Harris Hip score obtained 3 patients outcome was excellent, 18 patients were good and 4 patients had fair outcome.
Conclusion: Minimal exposure, better stability and early mobilization are the advantages with PFN. Fractures united in all cases and
postoperative functional outcome was satisfactory. PFN could be a preferred implant of choice in treating subtrochanteric fractures especially in
elderly.

Shoulder surgery varies from simple diagnostic arthroscopy to major total shoulder arthroplasty. Patients present for shoulder surgery may be
young and t with a sports injury or elderly sick with rheumatoid arthritis need arthroplasty of the shoulder joint. Choice of anaesthesia based on the
type of surgery, and the comorbidity of a patient. Management of severe postoperative pain is a major challenge for the anaesthesiologist. Regional
anaesthetic techniques effectively control static as well as dynamic pain and facilitate early mobilization. However regional blocks are not free
from the side effects or complications
A COMPARATIVE STUDY OF q SOFA(Quick SOFA) SCORE AGAINST SIRS CRITERION AS A PROGNOSTIC TOOL IN INFECTED PATIENTS REQUIRING EMERGENCY ADMISSION.

Published: June 2021

INTRODUCTION: Sepsis, a syndrome of physiological, pathological, and biochemical abnormalities induced by infection and is dened as lifethreatening organ dysfunction that is caused by a dysregulated host response to infection (11).It is a common cause of admission to the ICU and can
lead to multiple organ dysfunction syndrome and death (12). It is essential to differentiate sepsis from uncomplicated infection because sepsis is
associated with poor outcomes (13). Early recognition of sepsis can improve outcome of these patients through corresponding interventions (13).
However because sepsis is a complex,heterogeneous,disease it is often difcult for clinician to promptly identify patient with sepsis.
The qSOFAhas merit according to its proponents. It is simple (consisting of three clinical elements ,namely hypotension , tachypnoea , and altered
consciousness), it can be easily and repeatedly assessed , it was generated through a data driven approach ,and in a large retrospective study, it was
more accurate than SIRS for predicting death and ICU transfer of patient with suspected sepsis outside the ICU. (16, 17, 18).
MATERIALAND METHODS: This study was a single centre observational prospective study conducted in Surgery emergency (department of
surgery) Nehru hospital, BRD Medical College, Gorakhpur for a period of 12 months.
CONCLUSION: Identication of ED patients with infection who ultimately survive but are in the need for early critical care intervention may be
helpful in minimising in hospital mortality. qSOFAand SIRS scores can be useful clinical tools in decision making in emergency department.

Background- Pityriasis lichenoides is a benign disease that includes a continuous spectrum with two polar ends: pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC). It is a rare papulosquamous disorder of unknown etiology. Phototherapy (NBUVB) can be a safe and effective treatment for PLC in children. Objective- To assess the safety and efcacy of Phototherapy in children with PLC. Material and Methods- A prospective, single-center open-label uncontrolled study conducted at tertiary care hospital in Dermatology Outpatient department (OPD) between January 2018 to April 2019. A total of 12 patients were included in the study who were diagnosed as PLC. All the patients undergone phototherapy as a treatment modality. Result- Phototherapy was proved to be an efcient modality in treating PLC in children. Good response was seen in 58.3% of patients by the end of th 30 sitting. Conclusion- PLC is a chronic disease with remission and relapses. Narrow band UVB is an effective and safe modality of treatment for children.
