Authors: Dos Santos Walbermark M. , Martins Denizar C.
Published: July 2018

A diversificação de fontes geradoras de energia elétrica e a inserção cada vez maior da eletrônica de potência nos sistemas elétricos têm incentivado a pesquisa de conversores que apresentem bidirecionalidade de energia, grande densidade de potência, fácil controle e implementação, modularidade, etc. Diversos conversores atendem a essas especificações; todavia, o conversor DAB (Dual Active Bridge) tem recebido uma atenção especial da comunidade científica, pois apresenta robustez e isolamento galvânico entre as fontes, dentre outras vantagens. Dessa maneira, este artigo tem o intuito de apresentar, de forma sucinta, clara e objetiva, o referido conversor, destacando-se as relações matemáticas relevantes para o entendimento da estrutura e suas principais formas de onda. O presente trabalho também discerne sobre os procedimentos de projeto do conversor, empregando a teoria do gyrator. Resultados de simulação e experimentais são apresentados para validar as análises da topologia.

Published: July 2018

Este trabalho propõe uma metodologia de controle de injeção de potência ativa, incluindo a funcionalidade de compensação de reativos, para um inversor monofásico em ponte completa com filtro LCL (FB-VSI-LCL), aplicado à geração distribuída conectada com a rede elétrica em corrente alternada. Propõem-se o uso da linearização pela realimentação dos estados, uma técnica de controle não-linear, em conjunto com as desigualdades matriciais lineares (LMI) e critérios da D-estabilidade, com o objetivo de projetar os controladores para o sistema. O controle do fluxo de potência é realizado a partir do controle do inversor como fonte de corrente, e a partir das equações características P-f e Q-V determina-se o sinal de referência para a malha de tensão. Posteriormente, a malha de tensão gera o sinal de referência para a malha de corrente, sendo assim, o controle é realizado por um sistema multimalhas. Finalmente, os principais resultados experimentais são apresentados, considerando-se um protótipo com potência nominal de 1000VA, com a finalidade de demonstrar a funcionalidade do controle proposto.

Published: July 2018

Este trabalho apresenta um estudo sobre o projeto e compensação de parâmetros de um transformador de núcleo separado (TNS) usado como circuito de interface de um sistema de transferência de energia elétrica para alimentar um veículo autônomo subaquático (AUV). O circuito de interface transfere energia sem contato elétrico para carregar a bateria de um AUV. Os valores das resistências e reatâncias do circuito equivalente do TNS são determinados experimentalmente a partir da medição da tensão, corrente e potência entrada obtidos com dois ensaios a vazio e um ensaio em curto circuito. Capacitores série e paralelo são conectados aos terminais de entrada e saída do transformador para compensar as indutâncias de dispersão e aumentar o fluxo de magnetização. Uma rotina matemática é usada para otimizar os valores das capacitâncias para aumentar a eficiência e a tensão de saída, induzida no enrolamento secundário do TNS, uma vez que o entreferro do transformador pode variar com a precisão do processo de docagem do AUV. Resultados experimentais são apresentados para validar as análises teóricas e demonstrar o comportamento do transformador para diferentes valores de entreferro, frequência de excitação e da carga.

Authors: Marques-Ferreira Manuel , Carrilho Eunice , Paulo Siri , Carrilho Teresa , Figueiredo José Pedro , Macedo Ricardo
Published: July 2018

Introduction: This study aimed to compare the analgesic efficacy and the influence of local infiltrative anesthesia techniques, with diploe anesthesia, on the cardiac rhythmMaterial and Methods: We selected 32 healthy volunteers who were given both anaesthetic techniques on tooth 1.4 (0.45 mL of lidocaine with adrenaline, 1:80 000). In the first phase, the volunteers underwent periapical infiltrative anaesthesia. In the second phase, diploe anaesthesia was performed with a QuickSleeper® device. The parameters analysed were pulp response to the electrical test and heart rate of the participants. These parameters were evaluated on five different occasions: before anaesthesia (t0), immediately after anaesthesia (t1), 15 minutes later (t15), 30 minutes later (t30) and 60 minutes later (t60). Statistical analysis of the data was performed using SPSS 2.0 software, with α = 0.05.Results: With the diploe anaesthesia, a level of analgesia was obtained faster. There was a slight increase in heart rate soon after administration of diploe anaesthesia, which stabilized after t15 of the procedure. This technique still proved to be painless.Conclusion: Diploe anaesthesia demonstrated better results in terms of analgesia than the infiltrative anaesthesia. It has been reported to be easy, safe and an effective procedure that allows anaesthesia in almost all clinical situations. This approach may offer particular advantages for endodontic therapy, providing greater comfort for the patient.

Published: July 2018

Introduction: This study analyzed the incidence and characteristics of injuries sustained by amateur youth football players in Portugal during season 2015 - 2016.Material and Methods: This is an observational descriptive study. We analyzed Portuguese youth football players’ injuries over six months of a season. A total of 529 players were divided according to their age in two groups (Under-17 and Under-19). Data on injuries were collected.Results: Throughout all 62 062.0 hours of exposure recorded, 248 injuries were reported in 173 different players. The average incidence of injury was 3.87 (95% CI = 2.81; 4.94) per 1000 hours of football exposure. There was a significantly higher average incidence of injury during matches – 14.22 (95% CI = 10.35; 18.09) per 1000 hours of exposure – when compared to the average incidence of injury during training – 2.06 (95% CI = 1.22; 2.90) per 1000 hours of exposure. This significance was also observed when the comparison was made within each age group. A traumatic mechanism was involved in 76.6% of all the injuries, while overuse was reported in 12.9%. The most common type was the injury that affected muscles and tendons (52.8%). The body location most commonly affected by injuries was the thigh (24.6%).Discussion: Even though is essential a better characterization of Portuguese athletes of younger age groups such as those discussed in this study, the results of the studied population are in agreement with the existing literature. However, this study provides more information that may be important to better target the Portuguese athletes’ training for injury prevention.Conclusion: This study provides descriptive data on injuries developed in a subpopulation of Portuguese amateur youth football players that could represent a focus for future prevention.

Increased HIF-1alpha And VEGF Expression Found in Various T Stages of Clear Cell Renal Cell Carcinoma
Authors: Octavianda Yohana , Rahaju Anny Setijo
Published: July 2018

There is an increase in renal cell carcinoma in males aged over fifty years with smoking risk factors. Clear cell renal cell carcinoma is the most common malignant tumor found in the kidneys that have an aggressive nature. This carcinoma is classified according to TNM into T1, T2, T3 and T4 stages. The higher the T stage, the worse the prognosis of the patient, as it involves the role of the HIF-1a transcription factor accumulated under hypoxic condition due to inactivation of VHL, thus activating VEGF. So far, clear cell renal cell carcinoma frequently found in smoking males of fifth decade of age or older has not been explained.. An observational analytic study was conducted on the sample of paraffin blocks of patients with clear cell renal cell carcinoma in 2010-2016. T1, T2, T3, and T4 stages of 9 samples, 12 samples, 12 samples and 6 samples, respectively, were collected in Anatomic Pathology Laboratory, Dr. Soetomo Hospital, Surabaya. Detection of HIF-1a and VEGF expression was performed using immunohisto-chemical immunity with HIF-1a and VEGF antibodies. The results were analyzed statistically by Kruskal-Wallis and Mann-Whitney methods. The correlation between HIF-1a and VEGF in T stages was analyzed using Spearman method. There was a difference of HIF-1a expression between stage T1 with T2, T1 with T3, T1 with T4 (p=0.041, p=0.000, and p=0.002), stage T2 with T3 and stage T2 with T4 (p=0.001, and p=0.013). There was a difference in VEGF expression in stage T1 with T2, T1 with T3, T1 with T4 (p=0.007, p=0.000, and p=0.002), and stage T2 with T3 (p=0,001). There was a correlation between HIF-1a and VEGF expressions with all T stages (rs=0.624 with p 0.000). As a conclusion, the higher the stage of T, the higher the expression of HIF-1a and VEGF. The higher the levels of HIF-1a and VEGF, the worse the prognosis of clear cell renal carcinoma. HIF-1a and VEGF play a role in the pathogenesis of clear cell renal cell carcinoma. Thus, HIF-1a and VEGF can be developed as prognostic markers. Increased Hif-1aAnd Vegf Expression Found In Various T Stages Of Clear Cell Renal Cell Carcinoma

Published: July 2018

Pseudomonas aeruginosa is one of the Gram-negative rods bacteria that frequently cause nosocomial pneumonia. One of the main virulent effector proteins on Type III secretion system (TTSS) of P. aeruginosa is Exoenzyme U ( ExoU). ExoU works as a phospholipase A2 activity and exhibits lung tissue injury effect in pneumonia. As an antibiotic that has activity against P. aeruginosa, fluoroquinolone resistance has increased as many as three fold since the last decade. Infections caused by P. aeruginosa that are fluoroquinolone resistant and positive for ExoU gene show worse clinical outcome. The aim of this study was to determine the positivity of ExoU gene TTSS and fluoroquinolone resistance of P. aeruginosa that isolated from sputum of nosocomial pneumonia patients in Sanglah Hospital, Bali. P. aeruginosa isolated from sputum of patient that diagnosed as nosocomial pneumonia, isolates had been identified phenotypically by Vitek2 Compact system (bioMérieux, Inc., Marcy-l'Etoile - France), and then continued by genotypic detection by PCR. The susceptibility testing of P. aeruginosa isolates to Ciprofloxacin were conducted by Vitek2 Compact, whereas ExoU genes were detected by PCR. Fifty-three P. aeruginosa isolates were identified in this study, in which 35 isolates (66.1%) had ExoU gene and 22 isolates (41.5%) were resistant to Ciprofloxacin. Based on nosocomial pneumonia type, the highest proportion of isolates genotipically ExoU+ and phenotypically Ciprofloxacin were on VAP group accounted for 57.1% and 54.5%, respectively. Chi-square analysis showed significant correlation between Ciprofloxacin resistance and ExoU gene (p=0.001). As a conclusion, the positivity of ExoU+ isolates were more likely found in Ciprofloxacin resistant group.

Published: July 2018

Stroke is a neurological disease whose occurrence increases from year to year and causes disability and death worldwide. Stroke is caused by many factors or multicausal. This was a qualitative study conducted for one year with system design using prototype method. The prototype method began with the identification of needs, mapping, and then inference mechanism. Identification of needs was based on the literature review and discussion. The literature review from 15 sources consisting of journal articles, books and proceedings was done by comparing, contrasting, criticizing, synthesizing and summarizing. Stroke risk factor discussion were carried out with neurologists. The results of the review and literature discussion found identification of factors that cause stroke, which consisted of hypertension, high blood glucose, cholesterol, heart disease, behavioral factors, such as smoking behavior and alcoholism, stress and other causes. The risk factors of stroke were then mapped in the form of mobile application prototype through inference mechanism. The output in this study was early warning systems (E-WARS) prototype for early detection of stroke occurrence. The prototype results were expected to be used in operations into mobile applications that were beneficial to the public, in particular for self-control and personal risk factors for stroke. It was intended for early screening and early detection of the risk of stroke.

Published: July 2018

Children of primary school are particularly vulnerable to schistosomiasis because 60-70% of them with age of 5-14 years do a lot of activity outside home. The impact of schistosomiasis in children are the lack of concentration in learning, anemia, and impaired growth. This study aimed to describe the behavior of children aged 7-12 years in Puro'o and Tomado Villages in preventing the transmission of schistosomiasis and to determine the correlation between age, sex behavior community in the prevention of schistosomiasis. The study was conducted in Tomado and Puro'o villages for 3 months from March to June 2016. This was a cross sectional study. The samples in this study were children aged 7-12 years, selected by stratified multistage random cluster sampling which was done in three phases: the first phase was the villages, the second phase was the primary school in the village, and the third stage was household selected by proportional random sampling. Data were collected through interview using a structured questionnaire and the observation was analyzed using chi-square test. Respondents who had less knowledge, mostly behave defecate/urinate (80%) in latrine/WC, handwashing behavior with soap after defecating/urinating (50%), wearing footwear outside the home (86.5%), and playing in the rice fields, marshes and lakes (67.3%). Analysis of the relationship between knowledge and child's behavior showed no significant relationship (p=0.114). As a conclusion, children aged 7-12 years in Tomado and Puro'o villages mostly had less supportive behavior in preventing the transmission of schistosomiasis and had moderate or less reliable knowledge.

Published: July 2018

Integrated ultra-low-loss waveguides are highly desired for integrated photonics to enable applications that require long delay lines, high-Q resonators, narrow filters, etc. Here we present an ultra-low-loss silicon waveguide on 500 nm thick SOI platform. Meter-scale delay lines, million-Q resonators and tens of picometer bandwidth grating filters are experimentally demonstrated. We design a low-loss low-reflection taper to seamlessly integrate the ultra-low-loss waveguide with standard heterogeneous Si/III-V integrated photonics platform to allow realization of high-performance photonic devices such as ultra-low-noise lasers and optical gyroscopes.
Molecular Mechanisms Underlying Lubrication by Ionic Liquids: Activated Slip and Flow
Authors: Han Mengwei , Espinosa-Marzal Rosa M.
Published: July 2018

The present study provides molecular insight into the mechanisms underlying energy dissipation and lubrication of a smooth contact lubricated by an ionic liquid. We have performed normal and lateral force measurements with a surface forces apparatus and by colloidal probe atomic force microscopy on following model systems: 1-ethyl-3-methyl imidazolium bis-(trifluoro-methylsulfonyl)imide, in dry state and in equilibrium with ambient (humid) air; the surface was either bare mica or functionalized with a polymer brush. The velocity-dependence of the friction force reveals two different regimes of lubrication, boundary-film lubrication, with distinct characteristics for each model system, and fluid-film lubrication above a transition velocity V*. The underlying mechanisms of energy dissipation are evaluated with molecular models for stress-activated slip and flow, respectively. The stress-activated slip assumes that two boundary layers (composed of ions/water strongly adsorbed to the surface) slide pass each; the bond dynamics and the strength of the interaction at the slip plane dictate the change in friction -decreasing, increasing or remaining constant- with velocity in the boundary-film lubrication regime. Above a transition velocity V*, friction monotonically increases with velocity in the three model systems. Here, layers of ions slide past each (“flow”) under a shear stress and friction depends on a shear-activation volume that is significantly affected by confinement. The proposed friction model provides a molecular perspective of the lubrication of smooth contacts by ionic liquids and allows identifying the physical parameters that control friction.

Authors: Atar Ertan , Ersoy Okan
Published: July 2018

Compressive sensing (CS) is a technique that allows a signal vector to be reconstructed with a number of linear measurements far fewer than its size. In this study, optical hybrid cryptography with simultaneous compressive sensing based on orthogonal matching pursuit (OMP) is proposed as an alternative solution to the two important problems in communications, namely, effective / efficient / signal processing and secure encryption/decrypton. The whole system is able to both compress and encrypt data with attack immunity.

Published: July 2018

Neurodegenerative diseases like Alzheimer’s disease (AD) are poised to become a global health crisis, and therefore understanding the mechanisms underlying the pathogenesis is critical for the development of therapeutic strategies. Mutations in genes encoding presenilin occur in most familial Alzheimer’s disease but the role of PSEN in AD is not fully understood. In this review, the potential modes of pathogenesis of AD are discussed, focusing on calcium homeostasis and mitochondrial function. Moreover, research using Caenorhabditis elegans to explore the effects of calcium dysregulation due to presenilin mutations on mitochondrial function, oxidative stress and neurodegeneration is explored.

Authors: Mesa Francisco , Rodriguez-Berral Raul , Medina Francisco
Published: July 2018

A critical discussion on the computation of the dispersion diagram in periodic one-dimensional guiding structures is carried out. In particular, an analysis is presented of the pros and cons of combined methods that make use of full-wave simulations done with commercial software packages with further analytical post-processing based on simplifications brought by an equivalent circuit model of the structure. Some of the most common methods reported in the literature are reviewed and their advantanges and limitations highlighted. Our discussion is complemented with several selected numerical examples in order to discuss the most relevant aspects that a potential user of these methods should be aware of. Special attention is paid to the relevant role played by the high-order coupling between the two halves of a symmetric unit cell of the periodic structure.

Published: July 2018

Traditional Filuferru is an ancient spirit from Sardinia, Italy, usually obtained from the distillation of wine or grape marc. In this contribution, the results of the first chemical characterization of a wide number of craft Filuferru samples has been accomplished in terms of evaluation of the alcoholic strength, qualitative and quantitative GC-MS analysis of the volatile composition of the distillate, and its trace element composition by means a ICP-MS method. Both instrumental methods have been validated and applied on 21 craft samples of Filuferru, whereas one sample of commercial distillate has been analyzed for comparison purposes. Alcoholic strength ranged between 41.0 and 62.4% (v/v). Sixty volatile compounds were identified and ten of them have been quantified. Analogies and differences with Grappa (i.e. the Italian distilled spirit most close to Filuferru) have been highlighted in the qualitative and quantitative profile of this matrix. Often meaningful amounts of acetaldehyde, ethyl acetate, dietyl acetal and acetic acid were measured. Elemental analysis, performed on toxic, non-toxic elements and oligoelements, 18 in total, revealed a wide variability of concentrations in both analytes and samples. High concentrations of Cu are sometimes evidenced, likely caused by losses from the distillation apparatus. The principal components analysis (PCA) allowed the differentiation of the ten volatile compounds quantified in two groups: the former, described mainly by PC1, constituted by acetic acid, ethyl acetate, dietyl acetal and acetaldehyde, and the second, described by PC2, constituted by 1-propanol, 2-methyl-1-propanol, the two coeluiting isomers 2-methyl-1-butanol and 3-methyl-1-butanol,1-hexanol, 2-phenylethanol and 2,3-butanediol. Data obtained may be useful in order to establish a regulation for the production of high-quality traditional Filuferru from Sardinia.
Faithful Families Cooking and Eating Smart and Moving for Health: Evaluation of a Community Driven Intervention
Authors: Torrence Caitlin , Griffin Sarah F. , Rolke Laura , Kenison Kelli , Marvin Alta Mae
Published: July 2018

There is a growing need to utilize community interventions to address modifiable behaviors that lead to poor health outcomes like obesity, diabetes, and heart disease.  Poor health outcomes can be tied to community-level factors such as food deserts (identified areas with low access to fresh fruit, vegetables, and other healthful whole foods) and individual behaviors like sedentary lifestyles, consuming large portion sizes, and eating high-calorie fast food and processed foods. Through a social ecological approach with family, organization and community, the Faithful Families Cooking and Eating Smart (FFCES) intervention was created to address these concerns in a rural South Carolina community. FFCES used gatekeepers to identify 18 churches and 4 apartment complexes in low-income areas. 176 participants completed both pre- and post- survey measures. Student’s t-test measures found statistically significant change in participant perception of food security (0.39, p-value=0.005), self-efficacy with physical activity and healthy eating (0.26, p-value=000), and cooking confidence (0.17, p-value=.01). There was not significant change in cooking behaviors as assessed through the Cooking Behaviors Scale. FFCES shows that a social ecological approach can be effective at increasing and improving individual healthy behaviors and addressing community-level factors in low-income rural communities.
A Heuristic Method for Certifying Isolated Zeros of Polynomial Systems
Authors: Cheng Jin-San , Dou Xiaojie
Published: July 2018

We construct a real square system related to a given over-determined real system. We prove that the simple real zeros of the over-determined system are the simple real zeros of the related square system and the real zeros of the two systems are one-to-one correspondence with the constraint that the value of the sum of squares of the polynomials in the over-determined system at the real zeros is identically zero. After certifying the simple real zeros of the related square system with the interval methods, we assert that the certified zero is a local minimum of the sum of squares of the input polynomials. If the value of the sum of the squares of the input polynomials at the certified zero is equal to zero, it is a zero of the input system. As an application, we also consider the heuristic verification of the isolated zeros of polynomial systems and their multiplicity structures. Notice that a complex system with complex zeros can be transformed into a real system with real zeros.
A Brief History of Cloud Application Architectures: From Deployment Monoliths via Microservices to Serverless Architectures and Possible Roads Ahead
Authors: Kratzke Nane
Published: July 2018

This paper presents a review of cloud application architectures and its evolution. It reports observations being made during the course of a research project that tackled the problem to transfer cloud applications between different cloud infrastructures. As a side effect we learned a lot about commonalities and differences from plenty of different cloud applications which might be of value for cloud software engineers and architects. Throughout the course of the research project we analyzed industrial cloud standards, performed systematic mapping studies of cloud-native application related research papers, performed action research activities in cloud engineering projects, modeled a cloud application reference model, and performed software and domain specific language engineering activities. Two major (and sometimes overlooked) trends can be identified. First, cloud computing and its related application architecture evolution can be seen as a steady process to optimize resource utilization in cloud computing. Second, this resource utilization improvements resulted over time in an architectural evolution how cloud applications are being build and deployed. A shift from monolithic servce-oriented architectures (SOA), via independently deployable microservices towards so called serverless architectures is observable. Especially serverless architectures are more decentralized and distributed, and make more intentional use of independently provided services. In other words, a decentralizing trend in cloud application architectures is observable that emphasizes decentralized architectures known from former peer-to-peer based approaches. That is astonishing because with the rise of cloud computing (and its centralized service provisioning concept) the research interest in peer-to-peer based approaches (and its decentralizing philosophy) decreased. But this seems to change. Cloud computing could head into future of more decentralized and more meshed services.
Fluorescent Nanosensor based on Molecularly Imprinted Polymers Coated on Graphene Quantum Dots for Fast Detection of Antibiotics
Authors: Zhou Tongchang , Halder Arnab , Sun Yi
Published: July 2018

In this work, we firstly explored a mild, clean, and highly efficient approach for the synthesis of graphene quantum dots (GQDs). GQDs with carboxyl groups or amino groups, were prepared from one-pot environmentally friendly method assisted by hydrogen peroxide, respectively. It was proved that carboxyl groups played an important role in the fluorescence quenching. Based on these findings, we developed a novel fluorescent nanosensor by combining molecularly imprinted polymers (MIPs) with carboxyl functionalized GQDs for the determination of tetracycline (TC) in aqueous samples. The nanocomposite was prepared using a sol-gel process. GQDs-MIPs showed strong ﬂuorescent emission at 410 nm when excited at 360 nm, which was subsequently quenched in the presence of TC. Under optimum conditions, the fluorescence intensity of GQDs-MIPs decreased in response to the increase of TC concentration with good linearity rage of 1.0-104 µg L-1. The limit of detection was determined to be 1 µg L-1. The fluorescence intensity of GQDs-MIPs was more strongly quenched by TC compared to the corresponding non-imprinted polymers, GQDs-NIPs. With the high sensitivity, the material was also successfully worked for the detection of TC in real spiked milk samples.

However, its clinical application has been unexplored. This mixed methods prospective observational study explores the acceptability and usability of myfood24 in a clinical population, women with gestational diabetes (GDM). Women were recruited at their first diabetes antenatal clinic appointment. To assess acceptability and usability, they were asked to complete five 24-hour dietary recalls using myfood24 over two weeks and a user experience questionnaire; with a subset invited to participate in a one-to-one semi-structured interview. Of the 199 participants, mean maternal age was 33 years, mean booking BMI 29.7kg/m2, 36% primiparous, 57% White, 33% Asian. Of these 121 (61%) completed myfood24 at least once and 73 (37%) completed the user questionnaire; 15 were interviewed. Usability of myfood24 was measured using the System Usability Scale (SUS) and found to be good (mean 70.9, 95%CI 67.1, 74.6). Interviews identified several areas for improvement, including optimising its use for mobile devices. myfood24 appears to be acceptable and have potential to support self-management and behaviour change for women with GDM but requires adaptation to record blood glucose results alongside real-time tracking of diet.

The province of Macerata, Italy, is a topographically complex region which has been little studied in terms of its temperature and precipitation climatology. Temperature data from 81 weather stations and precipitation data from 55 rain gauges were obtained, and, following quality control procedures, were investigated on the basis of 3 standard periods: 1931-1960, 1961-1990 and 1991-2014. Spatial and temporal variations in precipitation and temperature were analysed on the basis of six topographic variable (altitude, distance from the sea, latitude, distance from the closest river, aspect, and distance from the crest line). Of these, the relationship with altitude showed the strongest correlation. Use of GIS software allowed investigation of the most accurate way to present interpolations of these data and assessment of the differences between the 3 investigated periods. The results of the analyses permit a thorough evaluation of climate change spatially over the last 60 years. Generally, the amount of precipitation is diminished while the temperature is increased across the whole study area, but with significant variations within it. Temperature increased by 2 to 3°C in the central part of the study area, while near the coast and in the mountains the change is between about 0 and 1°C,  with small decreases focused in the Appennine and foothill belt (-1 to 0°C). For precipitation, the decrease is fairly uniform across the study area (between about 0-200 mm), but with some isolated areas of strong increase (200-300 mm) and only few parts of territory in which there is an increase of 0-200 mm, mainly in the southern part of the coast, to the south-west and inland immediately behind the coast. The monthly temperature trend is characterized by a constant growth, while for precipitation there is a strong decrease in the amount measured in January, February and October (between 25 and 35 mm on average).

The color changes corresponding to chromophore structures in lignin caused by exposure of Eucalyptus（Eucalyptus grandis and E. urophylla）to heat were investigated. Eucalyptus wood samples were heated in saturated steam atmospheres for 10 h at 110℃, 130℃, and 150℃. The lignin was isolated before and after heat treatment. The physicochemical properties of the lignin and changes in chromophore structures during heat treatment was evaluated through wet chemical analysis, FTIR, UV-Vis, GPC, XPSand 13C-NMR. The color of the wood became darker and redder with the increase in pressure and temperature. Depolymerization and dehydration reactions occurred via demethoxylation with heat treatment in saturated steam at 110℃ or 130℃. Lignin condensed to form insoluble compounds after heat treatment in saturated steam at 150℃. G units increased and S units decreased through demethylation during heat treatment, as revealed by FTIR and 13C-NMR analysis.

The Law No. 21 of 2008 about Islamic banking, requires every Islamic business unit to spin-off if they have met the criterion. There are two spin-off’s methods can be selected by Islamic banks. The purpose of this research is to analyze the effect of spin-off method to profitability. The profitability indicator that used in this study is the return on asset. This study is using panel regression with random effect model. The result showed that spin-off method doesn’t have a significant impact on the Return On Asset (ROA) Islamic Banks from spin-off effect. Only BOPO and Non-Performing Finance (NPF) had a significant effect on Return On Asset (ROA). These results indicate that the Islamic business units that want to do the spin-off can choose one of two methods of the spin-off. The decision depends on the internal condition of Islamic business unit and the internal policies of conventional commercial banks.

Ozone is a triatomic allotrope of oxygen that can be produced in specially designed machines: ozone generators (ozonators). It breaks down to dioxygen (O2) and active atomic oxygen (O), which is a very strong oxidant. Due to the fact that its bactericidal, virucidal and fungicidal activities are 50 times more powerful than those of chlorine, ozone could be used in a wide range of applications, including disinfection, disinfestation and deodorization. Biochemical properties of ozone make it useful in both human and animal medicine. Ozone therapy has been applied in the treatment of cardiovascular and gastrointestinal tract diseases, many viral, bacterial and fungal infections, corneal diseases, skin disorders, as well as in inflammatory and degenerative joint diseases. Various forms of ozone are utilized for medical purposes, for example, ozone/oxygene mixture, dressing covered with ozonated water or oil, ozonated infusion fluids and ozonated autohemotherapy (AHT). Medical ozone appeared to be successful in the treatment of antibiotic-resistant infections, infected and nonhealing wounds. When properly conducted, ozone therapy is safe and non-toxic, and should therefore be widely used in veterinary and human medicine practice..
