Como a ameaça do terror influencia a estabilidade do sistema internacional e sua segurança: enfoque no direito internacional
Authors: Faria Ane Cristina Figueiredo Pereira de
Published: December 2017

Os ataques terroristas de 11 de setembro de 2001, mudaram as percepções de segurança nacional/internacional e a segurança humana. As intimidações de grupos rebeldes provenientes dos Estados falidos, têm deixado o sistema internacional em constante estado de alerta. Isto porque as atrocidades nos atentados e a frequência dos acontecimentos, apresentam uma real problemática a segurança global. Devido a complexidade do sistema internacional, reduzir as ameaças não é uma tarefa fácil, principalmente porque essas estão ligadas a falta de poder empregado por algumas nações. Por vezes, os Estados são coniventes ou ineficientes para proteger os direitos humanos e garantir a aplicabilidade do Direito Internacional, o que demanda intervenção externa para assegurar os mesmos. Mas além do Direito internacional, existem organizações que estão empenhadas no propósito de proteger a segurança humana e seus direitos, a exemplo da Organização das Nações Unidas. Mediante ao exposto, esse artigo buscou compreender como a ameaça do terror influencia a segurança e a estabilidade do sistema internacional frente ao Direito Internacional. Assim, aplicou-se o método bibliométrico e o trabalho utilizou-se da revisão sistemática, o que reduziu a pesquisa a quatro artigos que foram analisados de modo a entrelaçar a temática do terrorismo no sistema internacional e a não aplicação dos direitos internacionais ligados aos direitos humanos. O estudo expõem que, as ameaças provenientes de extremistas e seus atos de terror, têm colocado em dúvida a eficiência da segurança global, assim como, o modo que o sistema internacional interage mediante a atuação de atores não-estatais. A pesquisa ainda aborda que, apesar dos esforços de convenções e organizações para combater a guerra e o terror, muitos estudiosos apontam debilidades nos tratados e acordos entre os Estados para cumprir suas obrigações com o direito internacional. Porém, tais medidas seriam fundamentais para o bem estar coletivo e a segurança internacional.
Revisão contratual por onerosidade excessiva nas relações civis
Authors: Vasques Viviane da Silva Coelho
Published: December 2017

A lei permite a resolução ou revisão de contrato civil por ter a prestação de uma das partes da relação se tornado excessivamente onerosa com a extrema vantagem para outra, gerando profundo desequilíbrio contratual. Porém, não é qualquer contrato e tão pouco qualquer situação fática que se enquadra na legislação vigente. A presença de todos os requisitos exigidos é improvável no caso concreto, dificultando a aplicação do art. 478 e seguintes do Código Civil.
O novo código de processo civil e as disposições gerais aplicáveis às tutelas provisórias
Authors: Lovato Luiz Gustavo , Scheidt Emiliane
Published: December 2017

O presente artigo tem a sua área de interesse no Direito Processual Civil, sendo seu escopo jurídico o estudo das Tutelas Provisórias previstas no Novo Código de Processo Civil, analisando as disposições gerais aplicáveis. A celeridade processual vem sendo, cada vez mais, buscada pelos Tribunais, uma vez que é por meio daquela que o Estado dá cumprimento aos preceitos da razoável duração do processo e da eficiência, preconizados pela Constituição da República Federativa do Brasil de 1988 (CRFB/88), os quais são repetidos pela Legislação Processual Civil no plano infraconstitucional. Sob esta perspectiva, a pesquisa direciona-se ao posicionamento, predominantemente doutrinário, acerca dos aspectos que permeiam a concessão das Tutelas Provisórias de Urgência, especificamente no Processo Civil, apresentando a importância desse instrumento como forma de proporcionar às partes a entrega do bem da vida em tempo. Por fim, a pretensão desse trabalho não se resume em sanar todos os aspectos levantados na pesquisa, mas somente dar ampliação à matéria abordada.
A penhorabilidade dos rendimentos do trabalho no direito brasileiro e português: quando o credor da obrigação é também um trabalhador
Authors: Castro Carlos Alberto Pereira de
Published: December 2017

A presente pesquisa versa sobre a penhora, sob a ótica de sua natureza jurídica de garantia das obrigações, e o cabimento de sua incidência sobre os rendimentos do trabalho, especialmente na situação em que o credor da obrigação inadimplida e postulada em juízo é também um trabalhador, em um estudo comparativo entre a legislação portuguesa e brasileira. O tema proposto parte da noção de penhora, com a abordagem da sua natureza – de garantia de obrigações – e analisa a possibilidade de penhora do salário, a partir da premissa de que esta é permitida tanto no ordenamento jurídico português como no brasileiro sob certas condições e apenas em numerus clausus. O problema que se pretende investigar é se, à vista dos ordenamentos português e brasileiro, em caso de o credor da obrigação exigida em juízo ser também um trabalhador, estaria o devedor liberado de sofrer a constrição judicial sobre os salários ou proventos. Discute-se, entrementes, a colisão de interesses – e de princípios – que se dá quando do embate argumentativo sobre as situações concretas levadas ao Poder Judiciário em que devedores de créditos trabalhistas alegam a impenhorabilidade de seus rendimentos decorrentes de atividade remunerada. A pesquisa envolve, por esta razão, além das disposições legais de ambos os países estudados, a Convenção nº 95 da Organização Internacional do Trabalho sobre proteção de salários e a jurisprudência de ambos os países, especialmente a do Tribunal Superior do Trabalho, que veda em absoluto a penhora de créditos de devedor existentes em conta bancária aberta para o recebimento de salários (denominada conta-salário). Como um novo Código de Processo Civil brasileiro passou a vigorar em março de 2016, a indagação deste relatório aspira verificar eventual superação do entendimento jurisprudencial supracitado, ante as novas disposições concernentes ao tema. Conclui-se, ao final, que os rendimentos dos empregados são passíveis de penhora para pagamento de obrigações de um credor que também seja um trabalhador, em razão da natureza do crédito trabalhista, pelo que se deve dar prevalência à satisfação do credor em detrimento de parcela dos rendimentos do devedor, sob pena de se estabelecer uma situação de grave iniquidade.

A Quick Guide to Statistical Modeling Design Defects, Product Liability and the Protective Properties of Suboptimal Nonparametric and Robust Statistics
Authors: Lang Michael
Published: December 2017

Statistical modeling lies at the heart of product design and development throughout numerous engineering disciplines, especially since processing large amounts of data has become increasingly ubiquitous. While mathematical statistics provide elegant guidance pertaining to the question of whether or not some particular underlying modeling assumptions are justified and appropriate, when pursuing a more comprehensive assessment of product design and development other considerations often increase in significance. Therefore, we will examine and analyze the tedious interactions and implications of statistical modeling choices and product liability exposure. To the best of our knowledge, this paper is the first to draw attention to and explore some often overlooked or oversimplified dangers and pitfalls that enter the equation when product design heavily relies on statistical modeling. In particular, through a diligent analysis of both statistical and legal aspects we will explore how statistically optimal procedures may yield far from optimal outcomes in terms of product liability when applied to actual real life problems and why suboptimal nonparametric or robust approaches may constitute better alternatives.

Euglena gracilis is an alga of great biotechnological interest and extensive metabolic capacity, able to make high levels of bioactive compounds, such as polyunsaturated fatty acids, vitamins and β-glucan. Previous work has shown that Euglena expresses a wide range of carbohydrate-active enzymes, suggesting an unexpectedly high capacity for the synthesis of complex carbohydrates for a single-celled organism. Here, we present an analysis of some of the carbohydrates synthesised by Euglena gracilis. Analysis of the sugar nucleotide pool showed that there are the substrates necessary for synthesis of complex polysaccharides, including the unusual sugar galactofuranose. Lectin- and antibody-based profiling of whole cells and extracted carbohydrates revealed a complex galactan, xylan and aminosugar based surface. Protein N-glycan profiling, however, indicated that just simple high mannose-type glycans are present and that they are partially modified with putative aminoethylphosphonate moieties. Together, these data indicate that Euglena possesses a complex glycan surface, unrelated to plant cell walls, while its protein glycosylation is simple. Taken together, these findings suggest that Euglena gracilis may lend itself to the production of pharmaceutical glycoproteins.
Design and Manufacturing of Conformal Cooling for Hot Stamping Dies Using Hybrid Process of Laser Metal Deposition (LMD) and Milling
Authors: Cortina Magdalena , Arrizubieta Jon Iñaki , Calleja Amaia , Ukar Eneko , Alberdi Amaia
Published: December 2017

Hot stamping dies include cooling channels to treat the formed sheet. The optimum cooling channels of dies & molds should adapt to the shape and surface of the dies, so that a homogeneous temperature distribution and cooling are guaranteed. Nevertheless, cooling ducts are conventionally manufactured by deep drilling, attaining straight channels unable to follow the geometry of the tool. Laser Metal Deposition (LMD) is an additive manufacturing technique capable to fabricate nearly free-form integrated cooling channels and therefore shape the so-called conformal cooling. The present work investigates the design and manufacturing of conformal cooling ducts, which are additively built up on hot work steel and then milled in order to attain the final part. Their mechanical performance and heat transfer capability has been evaluated, both experimentally and by means of thermal simulation. Finally, conformal cooling conduits are evaluated and compared to traditional straight channels. The results show that LMD is a proper technology for the generation of cooling ducts, opening the possibility to produce new geometries on dies & molds and, therefore, new products.
Low-Temperature Lattice Effects in the Spin-Liquid Candidate κ-(BEDT-TTF)2Cu2(CN)3

Published: December 2017

The quasi-two-dimensional organic charge-transfer salt κ-(BEDT-TTF)2Cu2(CN)3 is one of the prime candidates for a quantum spin-liquid due the strong spin frustration of its anisotropic triangular lattice in combination with its proximity to the Mott transition. Despite intensive investigations of the material's low-temperature properties, several important questions remain to be answered. Particularly puzzling are the 6 K anomaly and the enigmatic effects observed in magnetic fields. Here we report on low-temperature measurements of lattice effects which were shown to be particularly strongly pronounced in this material (R. S. Manna et al., Phys. Rev. Lett. 104, 016403 (2010)). A special focus of our study lies on sample-to-sample variations of these effects and their implications on the interpretation of experimental data. By investigating overall nine single crystals from two different batches, we can state that there are considerable differences in the size of the second-order phase transition anomaly around 6 K, varying within a factor of 3. In addition, we find field-induced anomalies giving rise to pronounced features in the sample length for two out of these nine crystals for temperatures T < 9 K. We tentatively assign the latter effects to B-induced magnetic clusters suspected to nucleate around crystal imperfections. These B-induced effects are absent for the crystals where the 6 K anomaly is most strongly pronounced. The large lattice effects observed at 6 K are consistent with proposed pairing instabilities of fermionic excitations breaking the lattice symmetry. The strong sample-to-sample variation in the size of the phase transition anomaly suggests that the conversion of the fermions to bosons at the instability is only partial and to some extent influenced by not yet identified sample-specific parameters.
Prediction Model of Photovoltaic Module Temperature for Power Performance of Floating PVs
Authors: Charles Lawrence K. Waithiru , Lim Jong Rok , Won Chang Sub , Ahn Hyung Keun
Published: December 2017

Rapid reduction in the $/Wp prices of photovoltaic (solar PV) energy has been proceeded recently, resulting in near exponential deployments with an annual capacity of 200 GW expected by 2020. Achieving high efficiency is necessary for many solar manufacturers to break even. In addition, new innovative installation methods are emerging to complement the improvement of system performance. The floating PV (FPV) solar market space has emerged over the past decade as a method for utilizing the cool ambient environment of the FPV system near the water surface to boost the power output performance of the PV module and ultimately the yield of the PV system. PV module temperature, which is the most critical factor affecting efficiency, ultimately governs the effective performance of solar cells, module, and all semiconductor materials in general. We propose the first ever electrical efficiency equations ( η c,FP V 1 and η c,FP V 2 ) for an FPV module installed on water based on two new predictions of FPV temperature operation models (Tm1 and Tm2), whose coefficients are derived from FPV site data with MATLAB. The theoretical prediction of module temperature shows respective errors of 2% and 4% when compared to the FPVM measured data.
Modelling Wetland Growing Season Rainfall Interception Losses Based on Maximum Canopy Storage Measurements
Authors: Ciężkowski Wojciech , Berezowski Tomasz , Kleniewska Małgorzata , Szporak-Wasilewska Sylwia , Chormański Jarosław
Published: December 2017

This study estimates rainfall interception losses from natural wetland ecosystems based on maximum canopy storage measurements. Rainfall interception losses play an important role in water balance, which is crucial in wetlands, and has not yet been thoroughly studied in relation to this type of ecosystem. Maximum canopy storage was measured using the weight method. Based on these measurements, daily values of interception losses were estimated and then used to calculate long term interception losses based on precipitation and potential evapotranspiration data for the 1971–2015 period. Depending mainly on the number of days with precipitation, the results show that total interception losses for the growing season as well as monthly interception losses are around 13% of gross rainfall. This value is similar to the values observed for some forests. Hence, interception losses should not be disregarded in hydrologic models of wetlands, especially because data trends in meteorological conditions (mainly number of days with precipitation) show that interception losses will increase in the future if those trends stay the same.
The Relationship between Autism Spectrum Disorder and Melatonin during Fetal Development
Authors: Jin Yunho , Choi Jeonghyun , Won Jinyoung , Hong Yonggeun
Published: December 2017

Autism spectrum disorder (ASD) refers to the diverse range of neurodevelopmental disorders accompanying impairments in social interaction, difficulties in communication, and stereotyped or repetitive behaviors. Unlike the older term, autism, the newer term, ASD, better reflects the broad range of autistic symptoms and denotes a single diagnostic category of autism accompanied by numerous conditions. The pineal hormone melatonin is a well-known neuroprotectant and circadian entrainer. This hormone crosses the placenta and enters the fetal circulation, then conveys photoperiodic information to the fetus during pregnancy. These actions enable normal sleep patterns and circadian rhythms, followed by normal neurodevelopment. Melatonin also reduces oxidative stress, which is harmful to the central nervous system. Therefore, melatonin acts as a neuroprotectant and circadian entrainer, and may reduce the risk of neurodevelopmental disorders such as ASD.

Published: December 2017

If we look at an overview of technology education in the world, we realize that technology education in professional education, as well as in ordinary education, plays an important role in supporting the idea of a technology-intensive Japan. This study focused on the trend of technology education in compulsory education in Japan. Compared to technology education in advanced countries, fewer class hours are spent on technology education in compulsory education in Japan. However, various attempts have been made with robots and programming, mostly under the subject “technology and home economics,” at junior high schools. In particular, the future development of programming education implementation can be expected. At the same time, schools face multiple problems, including class hours and a lack of full-time teachers. These problems must be solved to enhance technology education.

A robot that consists of a compact disc (CD) and an embedded microcomputer has been developed as a robotics learning tool for elementary and junior high school students. The students can program the robot to draw a variety of shapes by placing a pen in the center hole of the CD. As the movement track of the robot can be recorded, the students can preserve their devised program execution results. In addition, intuitive instructions can be used to control the robot. This allows to input the program by operating several push-button switches. The program instructions can be viewed on the robot’s 8 LEDs-display interface. This robot is a unique teaching tool, which can be used to learn the mechanism of the robot composed of sensors, actuators, and a computer, without using a personal computer.

This study develops teaching materials for mechatronics in higher education. Industrial societies require numerous mechatronics engineers, and most technical universities provide mechatronics exercises in their curriculums. However, it is difficult for teachers and students to modify and improve the mechatronic teaching materials because the provided materials are finished products. Therefore, a simple and inexpensive educational system is developed to overcome the disadvantages of the finished products. In this paper, an experimental apparatus is proposed for mechatronics education, and a practical example is presented that involves learning control methods, sensors, actuators, and mechanics.

Provinsi Jawa Barat merupakan provinsi lumbung tenaga kerja Indonesia yang bekerja di luar negeri. Di Provinsi Jawa Barat, Kabupaten Subang merupakan salah satu kabupaten yang menyumbang tenaga kerja Indonesia yang bekerja di luar negeri dengan jumlah yang besar. Secara nasional perkabupaten, Kabupaten Subang menempati urutan ke-11 penyumbang jumlah TKI yang bekerja di luar negeri. Berdasarkan sektor pekerjaanya, TKI asal Subang umumnya bekerja di sektor informal sebagai asisten rumah tangga. Banyak permasalahan yang dihadapi oleh TKI selama bekerja di luar negeri seperti kekerasan fisik, keterlambatan gaji, gaji tidak dibayar dan PHK sepihak, bahkan sampai ada yang meninggal dunia. Sepulangnya dari bekerja sebagai TKI di negara lain, kehidupan mantan TKI adakalanya tidak membaik, bahkan tidak sedikit yang kembali ke kehidupan semula dengan kondisi ekonomi yang tidak lebih baik. Sehingga tidak sedikit yang kembali menjadi TKI. Pada umumnya mereka kembali menjadi TKI karena tidak memiliki keterampilan yang dapat diandalkan untuk bekerja atau menyadi sirausaha di dalam negeri.

Published: December 2017

This article presents two observability inequalities for the heat equation over Ω× (0,T). In the first one, the observation is from a subset of positive measure in Ω× (0,T), while in the second, the observation is from a subset of positive surface measure on ∂Ω× (0,T). We will provide some applications for the above-mentioned observability inequalities, the bang-bang property for the minimal time, time optimal and minimal norm control problems, and also establish new open problems related to observability inequalities and the aforementioned applications.
Persona in MMO Games: Constructing an Identity Through Complex Player/Character Relationships
Authors: Milik Oskar
Published: December 2017

Studies of online interaction involving identity can be divided into two distinct categories. On the one hand, there is the study of the players, which often asks questions of a psychological or economic nature. On the other hand, there is the study of characters, which looks at issues of language or culture, and critical theory topics such as gender, class, and race online. While these two approaches have created a field of digital games research that provides many valuable resources and research projects, the separation between these topics is also limiting due to the complex and intertwined nature of online and offline interaction in the modern age. This paper presents a new definition of persona as an additional methodological concept that can be used to observe interaction in the online world, particularly as it applies to the presentation of an identity to others. This construct serves as a joint identity of character and player, combining these otherwise separate topics to allow for a greater depth of understanding of the actions and reasoning behind the characters and players of digital games. It is also applicable to other online contexts, such as social networking, livestreaming, and forum use.
Particle Removal From Sandbed Deposits in Horizontal Annuli Using Viscoelastic Fluids
Authors: Bizhani M.. , Kuru E..
Published: December 2017

This paper presents results of an experimental study on how fluid viscoelastic properties would influence the particle removal from the sandbed deposited in horizontal annuli. Water and two different viscoelastic fluids were used for bed-erosion experiments. The particle-image-velocimetry (PIV) technique was used to measure the local fluid velocity at the fluid/sandbed interface, allowing for accurate estimation of the fluid-drag forces and the turbulence stresses.

It was found that polymer fluids needed to exert higher level drag forces (than those of water) on the sandbed to start movement of the particles. Results have also shown that, at the critical flow rate of bed erosion, the polymer fluids yielded higher local fluid velocities and turbulent stresses than those of water. Moreover, the local velocity measurements by means of the PIV technique and the resultant bed-shear-stress calculations indicated that enhancing polymer concentration under the constant flow rate should also enhance the drag forces acting on the sandbed. However, these improved fluid hydrodynamic forces did not result in any improvement in the bed erosion. Therefore, the mechanism causing the delay in the bed erosion by polymer additives could not be explained by any decrease in the local fluid velocity and the turbulence.

The primary reason for the delayed bed erosion by the polymer fluids was suggested to be linked to their viscoelastic properties. Two possible mechanisms arising from the elastic properties of the polymer fluids that hinder bed erosion were further discussed in the paper. The stress tensor of the viscoelastic-fluid flow was analyzed to determine the normal stress differences and the resultant normal fluid force acting on the particles at the fluid/sandbed interface. The normal force induced by the normal stress differences of the viscoelastic fluid was identified as one of the possible causes of the delayed bed erosion by these types of fluids.

DYNAMIC PECULIARITIES OF MUDFLOWS IN THE AZERBAIJAN AREA OF THE GREAT CAUCASUS
Authors: Мамедов Д. , Mammadov J.
Published: December 2017

The paper features the dynamic peculiarities of mudflow deposits and the methods of their volume calculation. It was determined that peculiarities of torrents are defined by their dynamic and velocity. It was revealed that the relation of accumulation volume to the abrasion volume of the debris cone of the water stage gauge in Balakançhay. Talaçhay Mukhakhchay and Kurmukchay is 0.66; 0.014; 1.35 and 0.7 accordingly. The violation factor of the mudflows in the river basins also forms 0.37; 0.28; 0.56 and 0.30 accordingly. As for the general territory, the range stays within the limits of 0.03-059. It is determined that the rate of decrease in the surface of the catchment areas caused by mudflows is 5.14 mm on the Balakenchay river, 11.81 mm in the Talachay river, 9.44 mm in the Mukhakhchay river, 5.68 mm in the river Kurmukchay, 11.21 mm in the river Shinchay and 9.09 mm in the river Kish. The average value is 8.73 mm. The relatively high value of the washout intensity is characteristic of the catchment area of the Talachay river and the Shinchay river, which is due to the spread of fragile rocks, the presence of significantly exposed areas with great slope steepness and their dismemberment, as well as cost-effective deforestation.
Relevance of hydraulic modelling in planning and operating real-time pressure control: case of Oppegård municipality
Authors: Berardi Luigi , Simone Antonietta , Laucelli Daniele B. , Ugarelli Rita M. , Giustolisi Orazio
Published: December 2017

Technical best practices recommend pressure control as an effective countermeasure to reduce leakages in water distribution networks (WDNs). Information and communication technologies allow driving pressure reducing valves (PRVs) in real-time based on pressure observed at remote control nodes (remote real-time control – RRTC), going beyond the limitations of classic PRV control (i.e. with target pressure node just downstream of the device). Nowadays, advanced hydraulic models are able to simulate both RRTC-PRVs and classic PRVs accounting for unreported and background leakages as diffused pressure-dependent outflows along pipes. This paper studies how such models are relevant to support pressure control strategies at both planning and operation stages on the real WDN of Oppegård (Norway). The advanced hydraulic model permits demonstration that RRTC-PRVs in place of existing classic PRVs might reduce unreported and background leakages by up to 40%. The same analysis unveils that advanced models provide reliable evaluation of leakage reduction efforts, overcoming the inconsistencies of lumped indexes like the Infrastructure Leakage Index (ILI). Thereafter, the model allows comparison of three strategies for the real-time electric regulation of PRVs in some of the planned scenarios, thus supporting real-time operation of RRTC-PRVs.
Climatic and atmospheric indices teleconnection impact on the characteristics of frost season in western Iran

Published: December 2017

The large-scale variability of atmospheric and ocean circulation patterns cause seasonal climate changes in the Earth. In other words, climate elements are affected by phenomena like El Niño Southern Oscillation (ENSO), El Niño (NINO), and Northern Atlantic Oscillation (NAO). In this study the characteristics of the frost season over a 20-year period (1996–2015) from seven synoptic stations in western Iran were evaluated using support vector machine and random forest regression. Comparing determination coefficients obtained by these models between atmospheric and ocean circulation indices and the characteristics of the frost season showed a positive effect. Thus, the onset and the end of the frost season in this region were highly correlated with the Southern Oscillation Index (SOI) and NAO, respectively. In regions with lower correlations (central areas and some regions of Alvand Mountain), the role of the geographical factors, altitude and topography becomes more pronounced and the impact of the global indices is reduced. Cluster analysis was also conducted to detect patterns and to identify regions according to the effect of the atmospheric and oceanic indices on frost season, and three regions were identified. The largest correlations with global indices (in both models) belonged to the first and third classes, respectively. The results of this study could be applied for planning environmental and agricultural activities.

Published: December 2017

Background:

Lithium is a first-line treatment for bipolar disorder in adults, but its mechanism of action is still far from clear. Furthermore, evidences of its use in pediatric populations are sparse, not only for bipolar disorders, but also for other possible indications.

Objectives:

To provide a synthesis of published data on the possible mechanisms of action of lithium, as well as on its use in pediatric samples, including pharmacokinetics, efficacy, and safety data.

Methods:

Clinical trials in pediatric samples with at least one standardized measure of efficacy/ effectiveness were included in this review. We considered: i) randomized and open label trials, ii) combination studies iii) augmentation studies iv) case series including at least 5 patients.

Results:

Different and non-alternative mechanisms of action can explain the clinical efficacy of lithium. Clinical studies in pediatric samples suggest that lithium is effective in managing manic symptoms/episodes of bipolar disorder, both in the acute phase and as maintenance strategy. Efficacy on depressive symptoms/phases of bipolar disorder is much less clear, while studies do not support its use in unipolar depression and severe mood dysregulation. Conversely, it may be effective on aggression in the context of conduct disorder. Other possible indications, with limited published evidence, are the acute attacks in Kleine-Levin syndrome, behavioral symptoms of X-fragile syndrome, and the management of clozapine- or chemotherapy- induced neutropenia. Generally, lithium resulted relatively safe.

Conclusions:

Lithium seems an effective and well-tolerated medication in pediatric bipolar disorder and aggression, while further evidences are needed for other clinical indications.

Published: December 2017

Background:

Quantification of preservatives in herbal formulation, simultaneously by high
performance liquid chromatography analysis is very complex and involves series of steps including
sample preparation, selection of suitable mobile phase and its validation for routine applications.

Introduction: Application of Quality by Design (QbD) in the development of novel, simple, accurate
and precise RP-HPLC method for concurrent quantification of quaternary preservatives in herbal formulation,
focusses on development of robust method.

Methods:

Isocratic analysis was carried out using C18 column at 231 nm. Risk assessment studies were
executed to determine the critical method parameters which were defined as acetonitrile volume in the
mobile phase, volume of injection and orthophosphoric acid concentration in the mobile phase. The
effect of the critical method parameters on critical method attributes, i.e. retention time, resolution and
chromatographic optimization function was further evaluated by means of central composite design and
the optimal conditions were determined through derringer’s desirability approach of multi-criteria decision
making technique.

Results:

The method was statistically validated according to ICH guidelines having good resolution
using optimized mobile phase, acetonitrile: 0.11% orthophosphoric acid in water (12.30: 87.70 % v/v)
giving acceptable retention time i.e. 3.7128 ± 0.0138 of bronopol, 4.5106 ± 0.00542 of sodium propyl
paraben, 10.7228 ± 0.029 of sodium benzoate and 12.252 ± 0.027 of sodium methyl paraben.

Conclusion:

Hence, the QbD based method development assisted in generating a design space with
knowledge of all method performance characteristics leading to a better understanding of the method,
and achieving desirable method quality.
Anticancer Activity of Resorcinarene-PAMAM-Dendrimer Conjugates of Flutamide

Published: December 2017

Methods: The synthesis of conjugates of flutamide with resorcinarene-PAMAM-dendrimers as well
as alkyl and ethyl phenyl chains in the lower part of the macrocycle as a nucleus and diethylenetriamines in the
dendritic branches gives the opportunity to obtain conjugates in one step of synthesis with 16 and 64 flutamide
moieties in the structure.

Results:

The in vitro anticancer studies showed that the conjugates of flutamide are more active than the free
flutamide and the flutamide derivatives, thus diminishing the amount of flutamide used. The resorcinarenedendrimer-
flutamide conjugates with a high drug payload improve the activity of the drug.

Conclusion:

This is important in delivering a sufficient amount of flutamide and suggests that the dendrimer
facilitates more of the drug being introduced into cells. It was also observed that the new conjugates are less
toxic than the anti-androgens.

Authors: Li Xue , Tong Tao , Lu Tiedao
Published: December 2017

The objective area is a complex fault-block reservoir, and is provided by China Petroleum Engineering Design Competition(CPEDC). Reservoir characteristics, including stratigraphic features, vertical changes and section properties (thickness, percentage sand and percentage amalgamation) are documented. Based on comprehensive analysis on structural architecture and reservoir characteristics, a three-dimensional quantitative reservoir modeling is taken at a regional-scale of 69×97×37 m3 with the application of geostatistics as theoretical guidance, and thus high-resolution hierarchical reservoir model is generated with a combination of hierarchical data, structural data, physical data and well trajectory data. Therefore, the established three-dimensional geological model integrates all well-point information and structural information, and provides a basic model for subsequent sedimentary microfacies modeling and property modeling as well. Finally, three-dimensional fence diagrams, connecting-well sections and well group profiles are built successively.
