ONTOLOGY OF THE TERM "PRINCIPLE OF COMPATIBILITY" IN RESTORATION DESIGNING
Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Egorova O.
Published: June 2018

The article raises the question of the relevance of the terminological base of modern restoration design. As an example, the terms "compatibility" and "compatibility principle" are considered, their conceptual spaces are designated, the essence of the application of these terms is disclosed. The ontological and gnoseological aspects of the concept of "compatibility" are designated as the fundamental principle of restoration design on the basis of an analysis of the basic terminological definitions, derived from dictionaries, textbooks and scientific literature. Based on the analysis of linguistic differences of the concept of "compatibility" in Russian, English and Italian, the essential differences in the use of this term are revealed, as well as in the implementation of the "compatibility principle" in the restoration of architectural monuments. The problem of understanding the term "compatibility", depending on the country and language, on which the term is interpreted, is considered. The article suggests a new definition of the concept of "compatibility", recommended for inclusion in the vocabulary of the restorer-designer.

Published: June 2018

Constraints often encountered by lecturers in educating students is still attached pedagogical mentality like students of secondary education; has not moved on andragogical mentality like a college student. These constraints can be found in the context of basic principles of andragogy. As a library research, this paper examines the data sources in the form of literature relevant to Islamic law (fiqh) studies and andragogy (adult education). The study results in six models of andragogical learning for the development of Islamic law (fiqh) courses in higher education. First, the learning model of “learn how to know” that emphasizes aspects of epistemology to increase students’ curiosity (need to know). Second, independent learning model that emphasizes student activeness in learning. Third, experiential based learning model, especially literature and field research practice, to foster inclusive thinking. Fourth, actual life-based learning model, either related to worship or muamalat. Fifth, contextual learning model to find alternative solutions to real life problems from the perspective of Islamic law (fiqh). Sixth, the learning model to develop students’ intrinsic motivation.

Multi-contract theory or hibryd contracts (al ‘uqud al murakkabah) is one of the new theory in contemporary Islamic jurisprudence and among academicians who did a study about the multi-contract in fiqh perspective is Abdullah bin Muhammad bin Abdullah al ‘Imrani. Some fatwa products of NSB-IUC also used this multi-contract theory. This research type is qualitative with descriptive-qualitative and descriptive-quantitative method, the retrieval data technique with a literature review to research multi-contract typology in NSB-IUC fatwas perspective al ‘Imrani multi-contract theory and its limits. The conclutions of this research are: (1) among five typology multi-contract perspectives al ‘Imrani multi-contract theory only found two kinds of multi-contract in NSB-IUC’s fatwas, which are first; mutaqabilah (totalled by 7 or 31.8%) and second; mujtami’ah (totalled bt 15 or 68.2%), while third (mutanafiyah), fourth (mukhtalifah), and fifth (mutajanisah) each of them are 0, which means no (0%) multi-contract with those three typologies; (2) as for multi-contract typology in NSB-IUC’s fatwas, it is al ‘Imrani multi-contract perspective limits which means all multi-contract does not contradict al ‘Imrani multi-contract limits, therefore it is allowed by Sharia, but there are some alternative multi-contract in fatwa products wich kind of doubtful (syubhat), moreover it could lead us to riba, like Pembiayaan Rekening Koran Syariah (PRKS) transaction especially in two multi-contract options, which are: wakalah-murabahah and wakalah-qardh.

​A malversação do reconhecimento no trabalho docente precarizado e intensificado
Authors: Silva Eduardo Pinto e , Ruza Fábio Machado
Published: June 2018

O objetivo deste artigo é analisar os paradoxos, os impasses e as (im)possibilidades do reconhecimento no/do trabalho do professor universitário. São apresentadas sínteses de três pesquisas: a primeira analisou trabalho, subjetividade e saúde em uma universidade em expansão; outra abordou o trabalho intensificado do professor em um programa de pós-graduação de excelência; e a terceira estudou o trabalho precarizado do tutor na educação a distância. As análises se articulam em torno dos seguintes eixos: trabalho, sociabilidade e subjetividade; malversação do reconhecimento, sofrimento e adoecimento; intensificação e precarização do trabalho. Conclui-se que a precarização-intensificação do trabalho engendra uma unidade contraditória de prazer-sofrimento na qual o reconhecimento é colocado em suspenso, quando não des-efetivado ou fraudado. Prevalecem o sofrimento e os processos patogênicos tão silenciados quanto insidiosos.

Clínica analítica de las organizaciones: una propuesta conceptual
Authors: Manrique Horacio , Lopera Isabel Cristina , Pérez Juan David
Published: June 2018

Como resultado de um estudo qualitativo do tipo hermenêutico, apresenta-se uma proposta para implementação em organizações de um método clínico. A base deste trabalho é uma base teórica na que alguns conceitos clássicos subjacentes a capacidade de articular os campos clínicos e organizacionais são revistos. O método clínico-analítico não é exclusivo para o campo da saúde e da doença, por outro lado, tem sido utilizado em campos tão diversos como direito, sociologia, pedagogia, entre outros. Este método envolve a operação de descomposição de discursos nos seus elementos constituintes. Aceita-se que as organizações são concreções de discursos fundantes (instituições) ou seja aceita-se que o método clínico-analítico é relevante para o estudo e intervenção. Além disso, argumenta-se também que os seres humanos constituem-se nas instituições. Aceitar estas premissas, implica que pode-se falar de um gerenciamento do ser humano de orientação analítica, cujos espaços de verbalização individual e grupal são essênciais, baseados em uma filosofia de gestão integrada. Como um resultado disso, propõe-se que esta gestão humana tende a ser analiticamente orientada ao indivíduo, ao grupo e ao desenvolvimento humano organizacional em geral.
A Relação Entre Estresse Ocupacional e Justiça Organizacional: Um Ensaio
Authors: Benzoni Paulo Eduardo , Ervolino Juliana Gomes , Simões Michel da Matta
Published: June 2018

O estudo do estresse ocupacional, suas fontes, dinâmica de funcionamento e consequências tem sido largamente estudado. Há consenso de que o ambiente de trabalho consiste em uma poderosa fonte de estresse ocupacional. Tomando o construto justiça organizacional, aventa-se a hipótese de que um ambiente de trabalho marcado por injustiças organizacionais pode ser um poderoso estressor, uma vez que exige constantes adaptações do indivíduo para lidar com tais injustiças. Este trabalho, de cunho teórico, propõe uma reflexão da relação entre os construtos estresse ocupacional e justiça organizacional, concluindo a partir da literatura que um ambiente de trabalho marcado por injustiças pode sim ser um potencial estressor e aponta a importância desta relação ser investigada empiricamente.
“As cobranças são pesadas, a gente sofre muita pressão”: as metas na vida de bancários
Authors: Perrone Claudia Maria , Santos Anelise Schaurich dos , Garcia Dias Ana Cristina
Published: June 2018

Este estudo objetivou compreender a percepção dos bancários sobre a organização das metas nas instituições financeiras, entender a visão que eles possuem sobre essas e investigar as repercussões das mesmas na vida dos empregados. Onze colaboradores de instituições financeiras públicas e privadas do Rio Grande do Sul/Brasil participaram de uma entrevista semiestruturada. As respostas foram submetidas à análise de conteúdo. Percebeu-se que as metas são constituídas de forma a transformar os funcionários em vendedores de produtos e serviços. Segundo a maioria dos bancários, as metas são difíceis de atingir e são uma imposição com repercussões na vida pessoal e profissional dos trabalhadores. A cobrança pelo cumprimento das metas seguidamente causa sofrimento nos bancários, podendo desencadear problemas de saúde.

Marxismo e Psicodinâmica do Trabalho: aproximações possíveis
Authors: Montalvão Luciano Alvarenga
Published: June 2018

O presente artigo tem como objetivo promover a aproximação entre o marxismo e a clínica psicodinâmica do trabalho a partir da reconstituição da categoria trabalho em ambos os modelos teóricos. No itinerário que levou Dejours da psicopatologia do trabalho à teoria do trabalho vivo – transitando por diversas bases teóricas e epistemológicas – a perspectiva recente do trabalho enquanto mediador da emancipação conduzirá o autor a uma aproximação crítica com Marx a qual, no nosso entendimento, abre um novo horizonte político para as nossas práticas clínicas orientadas pela psicodinâmica do trabalho. Em um contexto laboral marcado pelo triunfo da ideologia orgânica do capital e pelo esvaziamento do político, é tarefa necessária resgatar as potencialidades do trabalho para o estabelecimento de laços sociais de solidariedade e cooperação e colocar na ordem do dia a construção de uma nova política do trabalho.

Este artigo analisa as produções científicas publicadas nas revistas e periódicos das áreas de Psicologia e de Administração, entre 1996 e 2015, que propuseram a criação e/ou validação de instrumentos de medida utilizando análise inferencial, em temas ligados a afetos e bem-estar no trabalho, verificando escalas desenvolvidas no Brasil neste período, seus constructos e fatores, classificando-as de acordo com o escopo (novo instrumento, adaptação/versão brasileira de instrumento estrangeiro, validação fatorial com outras amostras/ ocupações) e com o foco (indivíduo ou contexto de trabalho). Utilizando-se base de dados em Excel com 860 artigos de Comportamento Organizacional, foram triados 26 artigos atendendo os critérios de terem medidas inferenciais nos subtemas Afeto e Bem-Estar no Trabalho. Os resultados demonstram que mais de um terço das escalas de medida quantitativa avaliadas correspondem aos temas de Bem-estar (19%) e de Satisfação no Trabalho (15%), que 42% dos artigos eram tradução/ adaptação de escalas estrangeiras, e 35% de criação e validação fatorial de escalas nacionais, e que 70% das medidas voltam-se para avaliação de características individuais, tornando então o trabalhador como variável de ajuste organizacional.  Considera-se que o direcionamento para replicações de medidas criadas ou já adaptadas ao Brasil, possibilitando novas evidências de validação fatorial, bem como sua efetiva publicação em periódicos da área de Psicologia e Administração, ampliaria a generalização dos resultados e o fortalecimento dos constructos teóricos desenvolvidos para os fenômenos organizacionais, para melhor divulgação e aplicação no contexto laboral.

Recent Advances in Applications of Acidophilic Fungal Microbes for Bio-Chemicals
Authors: Javaid Rehman , Sabir Aqsa , Sheikh Nadeem , Ferhan Muhammad
Published: June 2018

The processing of fossil fuels is the major environmental issue today which should be lessen. Biomass is gaining much interest these days as an alternate to energy generation. Lignocellulosic biomass (cellulose, hemicellulose and lignin) is abundant and has been used for a variety of purposes. Among them, the lignin polymer having phenyl-propanoid subunits linked together through C-C bonds or ether linkages, can produce numerous chemicals. It can be depolymerized by microbial activity together with certain enzymes (laccases and peroxidases). Both acetic acid and formic acid production by certain fungi contribute significantly to lignin depolymerization. Natural organic acids production by fungi has many key roles in nature that are strictly dependent upon organic acid producing fungus type. Fungal enzymatic conversion of lignocellulosic is beneficial over other physiochemical processes. Laccases, the copper containing proteins oxidize a broad spectrum of inorganic as well as organic compounds but most specifically phenolic compounds by radical catalyzed mechanism. Similarly, lignin peroxidases (LiP), the heme containing proteins perform a vital part in oxidizing a wide variety of aromatic compounds with H2O2. Lignin depolymerization yields value-added compounds, the important ones are BTX (Benzene, Xylene and Toluene) and phenols as well as certain polymers like polyurethane and carbon fibers. Thus, this review will provide a concept that biological modifications of lignin using acidophilic microbes can generate certain value added and environment friendly chemicals.
Sustainability as Source of Competitive Advantages in Mature Sectors: The Case of Ceramic District of Sassuolo (Italy)
Authors: Settembre-Blundo Davide , García-Muiña Fernando E. , Pini Martina , Volpi Lucrezia , Siligardi Cristina , Ferrari Anna Maria
Published: June 2018

Talking about sustainable development refers mainly to the environmental sphere, but the concept is much broader and also takes into account the social and economic conditions. The concept of sustainability, in this sense, is linked to the compatibility between the development of economic activities, the related social phenomena, and the protection of the environment. Therefore, the ability to balance social, economic and environmental sustainability is the very meaning of the concept of sustainable development. Firms that choose to develop policies and strategies to enhance and pursue sustainable development in the medium to long term have the burden of having to quantitatively document the improvements in production processes with the aim of sustainable development. As a result, one of the biggest challenges for European industry is to introduce sustainability principles into business models leading to competitive advantage. This is particularly important in raw material and energy intensive manufacturing sectors such as the ceramic industry. The present state of knowledge lacks a comprehensive operational tool for industry to support decision-making processes geared towards sustainability. In the ceramic sector, the economic and social dimensions of the product and processes have not yet been given sufficient importance. Moreover, the traditional research on industrial districts lacks an analysis of the relations between firms and the territory with a view to sustainability. Finally, the attention of scholars in the field of economic and social sustainability, has not yet turned to the analysis of the Sassuolo district. Therefore, in this paper we introduce the Life Cycle Sustainability Assessment (LCSA), as a method that can be a suitable tool to fill this gap, because through a mathematical model it is possible to obtain the information useful for decision makers to integrate the principles of sustainability both at the microeconomic level in enterprises, and at the meso-economic level for the definition of economic policies and territorial governance. Environmental and socio-economic analysis was performed from the extraction of raw materials to the packaging of the product on different product categories manufactured by the Italian ceramic industries of the Sassuolo district (northern Italy). For the first time the LCSA model, usually applied to unitary processes, is extended to the economic and industrial activities of the entire district, extending the prospect of investigation from the enterprise and its value chain to the integrated network of district enterprises.
Recent Developments in Using Drosophila as a Model for Human Genetic Disease
Authors: Oriel Christine , Lasko Paul
Published: June 2018

Many insights into human disease have been built on experimental results in Drosophila, and research in fruit flies is often justified on the basis of its predictive value for questions related to human health. Additionally, there is now a growing recognition of the value of Drosophila for the study of rare human genetic diseases, either as a means of validating the causative nature of a candidate genetic variant found in patients, or as a means of obtaining functional information about a novel disease-linked gene when there is little known about it. For these reasons, funders in the US, Europe, and Canada have launched targeted programs to link human geneticists working on discovering new rare disease loci with researchers who work on the counterpart genes in Drosophila and other model organisms. Several of these initiatives are described here, as are a number of output publications that validate this new approach.
Combination of Aronia, Red Ginseng and Shiitake Mushroom Potentiated Insulin Secretion and Reduced Insulin Resistance with Improving Gut Microbiome Dysbiosis in Insulin Deficient Type 2 Diabetic Rats
Authors: Yang Hye Jeong , Kim Min Jung , Kwon Dae Young , Kim Da Sol , Zhang Ting , Ha Chulgyu , Park Sunmin
Published: June 2018

The combination of freeze-dried aronia, red ginseng, ultraviolet-irradiated shiitake mushroom and natokinase (AGM; 3.4: 4.1: 2.4: 0.1) was examined to evaluate its effects on insulin resistance, insulin secretion and gut microbiome in a non-obese type 2 diabetic animal model. Pancreatectomized (Px) rats were provided high fat diets supplemented with either of 1) 0.5 g AGM (AGM-L), 2) 1 g AGM (AGM-H), 3) 1 g dextrin (control), or 4) 1g dextrin with 120 mg metformin (positive-control) per kg body weight for 12 weeks. AGM (1 g) contained 6.22 mg cyanidin-3-galactose, 2.5 mg ginsenoside Rg3 and 0.6 mg β-glucan. Px rats had decreased bone mineral density in the lumbar spine and femur and lean body mass in the hip and leg compared to the normal-control and AGM-L and AGM-H prevented the decrease. Visceral fat mass was lower in the control group than the normal-control group and its decrease was smaller by AGM-L and AGM-H. HOMA-IR was lower in descending order of the control, positive-control, AGM-L, AGM-H and normal-control groups. Glucose tolerance was deteriorated in the control group and it was improved by AGM-L and AGM-H more than in the positive-control group. Glucose tolerance is associated with insulin resistance and insulin secretion. Insulin tolerance indicated insulin resistance was highly impaired in diabetic rats, but it was improved in the ascending order of the positive-control, AGM-L and AGM-H. Insulin secretion capacity, measured by hyperglycemic clamp, was much lower in the control group than the normal-control group and it was improved in the ascending order of the positive-control, AGM-L and AGM-H. Diabetes modulated the composition of gut microbiome and AMG prevented the modulation of gut microbiome. In conclusion, AGM improved glucose metabolism by potentiating insulin secretion and reducing insulin resistance in insulin deficient type 2 diabetic rats. The improvement of diabetic status alleviated body composition changes and prevented changes of gut microbiome composition.  
Numerical Modeling and Performance Prediction of COS Hydrolysis Reactor in Integrated Gasification Fuel Cell
in terms of Thermo-Chemical Transport Phenomena
Authors: Noh Jung-Hun , Ko Dong-Shin , Lee Sung-Jong , Hur Deog-Jae
Published: June 2018

During the recent decades, global warming by greenhouse gas evolution has attracted worldwide attention and evermore strict regulations thereon have become institutionalized as international policies. In the process, more environment-friendly power generation technologies have been developed utilizing fossil fuels with a view to timely commercialization. As one of such “clean coal” technology, Integrated Gasification Fuel Cell system is a promising power generation means and COS hydrolysis reactor is installed downstream of coal syngas to remove acidic gas constituents such as H2S and COS. The most significant design parameters affecting performance of the COS hydrolysis reactor were selected to be GHSV, (catalytic) reaction temperature, and length ratio and numerical modeling was performed considering heat and fluid flow transfer as well as chemical reaction kinetics. Effect of the selected design parameters on the variation of conversion rate and reactant gas mixture concentration were comprehensively investigated to predict performance of COS hydrolysis reactor. Stochastic modeling of reactor performance was finally performed using Monte Carlo simulation and linear regression fitting.
General Quantile Time Series Regressions for Applications in Population Demographics
Authors: Peters Gareth
Published: June 2018

This paper has three objectives, the first is to present a detailed overview in the form of a tutorial for the developments of several key quantile time series modelling approaches. The second objective is to develop a general framework to represent such quantile models in a unifying manner in order to easily develop extensions and connections between existing models that can then be developed to further extend these models in practice. In this regard, the core theme of the paper is to provide perspectives to a general audience of core components that go into construction of a quantile time series model and then to explore each of these core components in detail. The paper is not addressing the concerns of estimation of these models, as there is existing literature on these aspects in many settings, we provide references to relevant works on these aspects in several classes of model. Instead, the focus is rather to provide a unified framework to construct such models for practitioners, therefore the focus is instead on the properties of the models and links between such models from a constructive perspective. The third objective is to compare and discuss the application of the different quantile time series models on several sets of interesting demographic and mortality based time series data sets of relevance to life insurance analysis. The exploration included detailed mortality, fertility, births and morbidity data in several countries with more detailed analysis of regional data in England, Wales and Scotland.
The Feasibility of Using Marble Cutting Waste in a Sustainable Building Clay Industry
Authors: El-Mahllawy Medhat S. , Kandeel Ayman M. , Latif Mahmoud L. , El Nagar Abdeen M.
Published: June 2018

This study evaluates the feasibility of stabilizing clay bricks with marble cutting waste (MCW). This waste currently discarded in huge quantities as a sludge resulted from sawing the marble blocks to slabs, grinding and polishing of marble processes to the landfills located around the marble processing factories located in the Shaq El-Thoban industrial zone, Cairo governorate, Egypt causing negative impacts on the environment, health and sustainable development. Experimental investigations were carried out to explore the effect of addition of the MCW in different clay-base mixes at different percentages up to 25% at the expense of the hydrated lime. Cement, hydrated lime and MCW are the three types of solidification agents used, clay and sand were also added in the formulations of the unfired clay brick specimens. Laboratory cylindrical stabilized and compressed specimens were made, and then they were cured in a humidity chamber for 2 and 4 weeks, then after were air dried, tested and evaluated according to the Egyptian code for the building by the stabilized and compressed earth soil (ECBS, 2016). To enhance the durability of the cured specimens, transparent silicon – based paint was used for this purpose. The laboratory results demonstrate high potential usage of MCW based additives up to 15% incorporating HL. In addition, the used paint could be an effective treatment way for the use of stabilized bricks in a wet environment. The use of eco-friendly building materials will be a great contribution for the environmental advantages and suggest a remarkable economical alternative to the fired building units.
Dental Adhesion Enhancement on Zirconia Inspired by Mussel's Priming Strategy Using Catechol
Authors: Park Minsoo , Ju Sungwon , Linstadt Roscoe , Ahn Jinsoo , Ahn Kollbe
Published: June 2018

Zirconia has recently become one of the most popular dental materials in prosthodontics being used in crowns, bridges, and to implants. However, weak bonding strength of dental adhesives and resins to zirconia surface has been a grand challenge in dentistry, thus finding a better adhesion to zirconia is urgently required. Marine sessile organisms such as mussels use a unique priming strategy to produce a strong bonding to wet mineral surfaces; one of the distinctive chemical features in the mussel’s adhesive primer proteins is high catechol contents among others. In this study, we pursued a bioinspired adhesion strategy, using a synthetic catechol primer applied to dental zirconia surfaces to study the effect of catecholic priming to shear bonding strength. Catechol priming provided a statistically significant enhancement (P < 0.05) in shear bonding strength compared to the bonding strength without priming, and relatively stronger bonding than commercially available zirconia priming techniques. This new bioinspired dental priming approach can be an excellent addition to the practitioner’s toolkit to improve dental bonding to zirconia.

Effects of Exogenous and Endogenous Attention on Metacontrast Masking
Authors: Agaoglu Sevda , Breitmeyer Bruno , Ogmen Haluk
Published: June 2018

To efficiently use its finite resources, the visual system selects for further processing only a subset of the rich sensory information. Visual masking and spatial attention control the information transfer from visual sensory-memory to visual short-term memory. There is still a debate whether these two processes operate independently or interact, with empirical evidence supporting both arguments. However, recent studies pointed out that earlier studies showing significant interactions between common-onset masking and attention suffered from ceiling and/or floor effects. Our review of previous studies reporting metacontrast-attention interactions revealed similar artifacts. Therefore, we investigated metacontrast-attention interactions by using an experimental paradigm in which ceiling/floor effects were avoided. We also examined whether metacontrast masking is differently influenced by endogenous and exogenous attention. We analyzed mean absolute-magnitude of response-errors and their statistical distribution. Our results support the hypothesis that metacontrast and endogenous/exogenous attention are largely independent with negligible likelihood for interactions. Moreover, statistical modeling of the distribution of response-errors suggests weak interactions modulating the probability of “guessing” behavior for some observers in both types of attention. Nevertheless, our data suggest that any joint effect of attention and metacontrast can be adequately explained by their independent and additive contributions.
Inhibition Effect of 3D Nanostructures on the Corrosion Resistance of 1-Dodecanethiol Self-Assembled Monolayers on Copper in Nacl Solution
Authors: Hu Shuai , Chen Zhenyu , Guo Xingpeng
Published: June 2018

A novel and simple method to improve the corrosion resistance of copper by constructing a 3D 1-dodecanethiol self-assembled monolayers (SAMs) in 3.5% NaCl solution is reported in this study. Several drops of 1% H3PO4 solution are thinly and uniformly distributed on copper surface to form a 3D nanostructure constituted by Cu3(PO4)2 nanoflowers. The anticorrosion properties of 1-dodecanethiol SAMs on copper surface and on copper surface treated with H3PO4 solution were evaluated. Results demonstrated that 1-dodecanethiol SAMs on bare copper surface exhibit good protection capacity, whereas a copper surface pretreated with H3PO4 solution can substantially enhance the corrosion resistance of 1-dodecanethiol SAMs.
A Proposal of Methodology for Designing Big Data Warehouses

Published: June 2018

Big Data warehouses are a new class of databases that largely use unstructured and volatile data for analytical purpose. Examples of this kind of data sources are those coming from the Web, such as social networks and blogs, or from sensor networks, where huge amounts of data may be available only for short intervals of time. In order to manage massive data sources, a strategy must be adopted to define multidimensional schemas in presence of fast-changing situations or even undefined business requirements. In the paper, we propose a design methodology that adopts agile and automatic approaches, in order to reduce the time necessary to integrate new data sources and to include new business requirements on the fly. The data are immediately available for analyses, since the underlying architecture is based on a virtual data warehouse that does not require the importing phase. Examples of application of the methodology are presented along the paper in order to show the validity of this approach compared to a traditional one.

An exploratory Life Cycle Assessment was carried out to provide insight into the environmental impacts of using the green seaweed Ulva spp. as a feedstock for production of bioplastic. The study focused on the production of lactic acid as a precursor of polylactic acid. The studied production process consists of (1) the cultivation of Ulva spp. in Integrated Multitrophic Aquaculture, (2) the processing of the biomass for solubilisation of sugars, (3) the fermentation of the sugars to lactic acid and (4) isolation of lactic acid from the fermentation broth. The study identifies environmental hotspots and compares the experimental seaweed production chain with conventional feedstock. The main hotspot identified is electricity consumption during seaweed cultivation. This impact of electricity consumption can be lowered by reducing energy use and sourcing renewable energy, and by improving the material efficiency in the product chain. To improve understanding of the environmental impacts of the production process, future studies can broaden the system boundaries and broaden the scope of sustainability issues included in the environmental assessment.

Time-Series Displacement of Landslide In Danba County (China) Monitoried By the Small Baseline Subset (SBAS) Technique
Authors: Hu Bo , Wu Yang
Published: June 2018

Landslide is a sliding movement of rock mass, debris and soil along the slope under the action of gravity. Small Baseline Subset (SBAS) is an established method for the investigation and monitoring of landslide moments. This study focuses on monitoring the long-temporal displacement of mountainous terrain in Danba County, Sichuan Province via SBAS technique, based on 31 scenes of L-band ALOS/PALSAR data from Feb. 2007 to Oct. 2010.The results show that the largest velocity rates in LOS direction are ±120 mm/yr and maximum accumulated displacement is up to -300, which indicates fast movement of the mountainous terrain during the observation time. These results get good consistency against the results of previous study. This demonstrates the strong potential of SBAS technique for monitoring the landslides geohazard.
Charged Dark Matters and Extended Standard Model
Authors: Hwang Jae-Kwang
Published: June 2018

The properties of the charged dark matters are discussed in terms of the new three-dimensional quantized space model. Because of the graviton evaporations, the very small Coulomb’s constant (k(dd)) of 10-48 k and large gravitation constant (GN(dd)) of 106 GN for the charged dark matters at the present time are expected. The tentative values of G and k are used for the explanation purpose. Therefore, Fc(mm) > Fg(dd) > Fg(mm) > Fg(dm) > Fc(dd) > Fc(dm) = 0 for the proton-like particle. Also, the gravitation constant has been changed with increasing of the time because of the graviton evaporation. In the present work, the B1, B2 and B3 bastons with the condition of k(mm) = k >> k(dd) > k(dm) = 0 are explained as the good candidates of the dark matters. Also, the particle creation, dark matters and dark energy could be deeply associated with the changing gravitation constants (G). It is expected that the changing process of the gravitation constant between the matters from GN(mm) ≈ 1036 GN to GN(mm) = GN happened mostly near the inflation period. Therefore, during most of the universe evolution the gravitation constant could be taken as GN(mm) = GN. And the effective charges and effective rest masses of the particles are defined in terms of the fixed Coulomb’s constant (k) and fixed gravitation constant (GN). Then, the effective charge of the B1 dark matter with EC = −2/3 e is (EC)eff = −2/3·10−24 e.
Multidimensional Analysis of Time-Resolved Charged Particle Imaging Experiments

Published: June 2018

We present a tutorial to realize a multidimensional fitting procedure capable of extracting all the relevant information contained in a sequence of charged particle images acquired as a function of time in femtosecond pump-probe experiments. The images are reproduced using a 3D fitting method, which provides the velocity (or center-of-mass kinetic energy) and angular distributions contained in the images and their time evolution. A detailed example of the method is shown through the analysis of the time-resolved predissociation dynamics of CH3I on the B-band origin [Gitzinger et al., J. Chem. Phys. 133, 234313 (2010)]. We show that the multidimensional approach is essential for the analysis of complex images that contain several overlapping contributions where reduced dimensionality analyses cannot provide a reliable description of the features present in the image sequence. This methodology can be generalized to many types of multidimensional data analysis.

Hepcidin-25 was identified as the main iron regulator in the human body by binding to the sole iron-exporter ferroportin. Studies showed that the N-terminus of hepcidin is responsible for this interaction, the same N-terminus that encompasses a small copper(II)-binding site known as ATCUN (amino terminal Cu(II)- and Ni(II)- binding) motif. Interestingly, this copper-binding property is largely ignored in most papers dealing with hepcidin-25. In this context, detailed investigations of the formed complex of hepcidin-25 with copper could reveal insights into its biological role. The present work is mainly focused on the study of the metal-bound form of hepcidin-25, which could be considered the biologically active form. The first part is devoted to the reversed-phase chromatographic separation of copper-bound and copper-free hepcidin-25, which was achieved by applying basic mobile phases containing 0.1% ammonia. Further, mass spectrometry (tandem mass spectrometry MS/MS, high resolution mass spectrometry HRMS) and nuclear magnetic resonance (NMR) spectroscopy were employed to characterize the copper-peptide. Lastly, a 3D model of hepcidin-25 with bound copper(II) is presented. The identification of metal complexes and potential isoforms and isomers, from which the latter usually are left undetected by mass spectrometry, led to the conclusion that complementary analytical methods are needed to characterize a peptide calibrant or reference material comprehensively. Quantitative nuclear magnetic resonance (qNMR), inductively-coupled plasma mass spectrometry (ICP-MS), ion-mobility spectrometry (IMS) and chiral amino acid analysis (AAA) should be considered among others.
