Aggregation Process and Mechanism of Pitch Deposits with Ca2+ in Papermaking White Water

The lipophilic colloidal substances (CS) in papermaking white water mainly originate from sizing agents applied during paper manufacturing operations and wood extractives, such as resin acids and fatty acids. In this study, the aqueous dispersions of sodium resinate and sodium stearate were used to simulate the colloidal substances concentrated in white water. The aggregation process and mechanism of pitch deposits developed from soluble colloidal particles were investigated by the determination of turbidity and zeta potential of colloidal substances simulacra dispersions as a function of Ca2+ concentration, as well as through morphological observation, structural characterization, and contact angle measurement of calcium-induced pitch deposits. The results showed that the micelles with hydrophilic groups extending in the water could be formed when the colloidal substances accumulated to a certain concentration. The Ca2+ can exchange Na+ of colloidal substance micelles, and hydrophobic pitch deposits can then be produced by either particle-particle collision or “layer by layer” adsorption with addition of Ca2+, or by both of the mechanisms mentioned above. The complete destabilization of the colloidal substance simulacra occurred when the Ca2+ concentration reached 5 mmol/L. The initial contact angles of water on the surfaces of calcium resinate and calcium stearate discs were 90.2° and 96.0°, respectively.
Copyright as a Rule of Evidence

This paper has been published in the Duke Law Journal. The Citation is 52 Duke L.J. 683 (2003). Many copyright doctrines serve to exclude from the copyright regime cases particularly prone to evidentiary complexity. The implicit logic is that for these cases the social costs of litigation would likely outweigh the social benefits derived from offering copyright protection in the first place. Doctrines that serve this evidentiary function include some doctrines where an evidentiary purpose is readily apparent, for example the requirement that eligible works be fixed in tangible form, and some where the link is quite subtle, for example the rule against protecting work that lacks creativity. Understanding these doctrines in this light helps to refine their proper scope and application. It also makes clear a problem facing copyright law more generally: the increasing divergence between the logical justifications for various copyright doctrines and their actual use by courts and commentators.
Improvement on reflectivity of chemical composition gratings at high temperatures

The development of the chemical composition gratings (CCGs) is described, and the influencing factors on reflectivity of CCGs in hydrogen‐loaded germanosilicate fibers have been studied.Experimental results show that improving the initial fiber Bragg grating (FBG) strength and enhancing the hydrogen concentration in FBGs inscription help to improve the reflectivity of the CCGs, and using different laser pulse energy of fabricating the FBGs has little effect on the reflectivity of CCGs. Finally the reasons of improving the reflectivity of CCGs are also discussed. © 2011 Wiley Periodicals, Inc.

Development of LED Street Lighting Controller for Wind-Solar Hybrid Power System

This paper presents the design and implementation of a wind-solar hybrid power system for LED street lighting and an isolated power system. The proposed system consists of photovoltaic modules, a wind generator, a storage system (battery), LED lighting, and the controller, which can manage the power and system operation. This controller has the functions of maximum power point tracking (MPPT) for the wind and solar power, effective charging/discharging for the storage system, LED dimming control for saving energy, and remote data logging for monitoring the performance and maintenance. The proposed system was analyzed in regard to the operation status of the hybrid input power and the battery voltage using a PSIM simulation. In addition, the characteristics of the proposed system's output were analyzed through experimental verification. A prototype was also developed which uses 300(W) of wind power, 200(W) of solar power, 60(W) LED lighting, and a 24(V)/80(Ah) battery. The control system principles and design scheme of the hardware and software are presented.
of S 2 International Conference on Internet of Things ICIOT 2016 DATAPROTECTIONINTHE INDUSTRIAL INTERNET OF THINGS

Theadvancement of low-cost sensors and Internet of Things (IoT) platforms has brought on a waveof changes in how companies deliver their products and services. The Industrial Internet of Things (IIoT) is a new industrial ecosystem that combines intelligent and autonomous machines, advanced predictive analytics, and machine-human collaboration to improve productivity, efficiency and reliability. In an increasingly competitive business environment, information is the most important asset for any industry. The integration of industrial and IoT creates various attack surfaces duringdata transmission, data collection, data storage, data analysis, data sharing, data outsourcinganddata publishing. The loss of sensitive information andother forms of enterprise information can lead tosignificant financial or business losses. Furthermore, the leakage of sensitive information related to external parties (e.g., external vendors) may cause reputational damage. In this paper, we will explore the impacts of data leakageanddata loss in the Industrial IoT. Several of the data protection challenges and opportunities at different data processingstages, and the impact of privacy leakagefor smart manufacturingare demonstrated.
Linear Total Variation Approximate Regularized Nuclear Norm Optimization for Matrix Completion

Matrix completion that estimates missing values in visual data is an important topic in computer vision. Most of the recent studies focused on the low rank matrix approximation via the nuclear norm. However, the visual data, such as images, is rich in texture which may not be well approximated by low rank constraint. In this paper, we propose a novel matrix completion method, which combines the nuclear norm with the local geometric regularizer to solve the problem of matrix completion for redundant texture images. And in this paper we mainly consider one of the most commonly graph regularized parameters: the total variation norm which is a widely used measure for enforcing intensity continuity and recovering a piecewise smooth image. The experimental results show that the encouraging results can be obtained by the proposed method on real texture images compared to the state-of-the-art methods.

Parser hybridisation for natural languages.

Identifying and establishing structural relations between words in natural language sentences is called Parsing. Ambiguities in natural languages make parsing a difficult task. Parsing is more difficult when dealing with a structurally complex natural language such as Arabic, which contains a number of properties that make it particularly difficult to handle. In this paper, we briefly highlight some of the complex structure of Arabic, and we identify different parsing approaches (grammar-driven and data-driven approaches) and briefly discuss their limitations. Our main goal is to combine different parsing approaches and produce a hybrid parser, which retains the advantages of data-driven approaches but is guided by grammatical rules to produce more accurate results. We describe a novel technique for directly combining different parsing approaches. Results for initial experiments that we have conducted in this work, and our plans for future work is also presented.
Socio-economic implications of bovine liver rejection in a major abattoir in south-western Nigeria

This study considered the common causes of liver rejection in an abattoir in Nigeria. It was estimated and compared mathematically the lead causes of rejection of bovine liver. Fascioliasis was the main cause of liver condemnation and its social and economic implications were studied. A total of Nigerian Naira 15,772,200 [US$134,000] was lost directly due to this disease condition in a three-year period and in a single abattoir. Finally, advice was proffered to minimize the problems associated with liver rejection in Nigeria and to improve public health and animal welfare.
Parameter Uncertainty and the Credit Risk of Collateralized Debt Obligations

This paper examines empirical challenges inherent in evaluating the credit quality of collateralized debt obligations (CDOs). In order to assess the likelihood and expected severity of a CDO tranche's losses, one needs to know the distribution of losses for each collateral asset backing the CDO, as well as the dependence of losses across collateral assets. Rating agencies and other market participants rely almost exclusively on simple copula models to describe the distribution of CDO collateral losses. For more senior CDO tranches, standard credit risk metrics such as probability of default and expected loss are highly sensitive to copula model parameters that are not directly observable. Given assumptions about the data available to a credit analyst, I compute bounds on the accuracy of copula model parameter estimators and show that in applied settings data constraints are likely to impose severe limitations on an analyst's ability to accurately evaluate CDO tranches. Thus, commonly used indicators of CDO credit quality such as credit ratings should be viewed as more preliminary and less informative than comparable indicators for unstructured corporate bonds.
Title : A unified model of human semantic knowledge and its disorders

similarity structure that provided a basis for knowledge generalization. Rumelhart 469 showed that the same principles explain how propositional semantic knowledge could be 470 encoded in the weights of a feed-forward network that learned distributed internal 471 representations. In a book and a series of papers, Rogers and McClelland argued that 472 Rumelhart’s model offered a new, unified account of several previously puzzling phenomena in 473 the study of semantic cognition, including results from studies of semantic knowledge in infancy 474 and childhood, healthy adulthood, and in semantic dementia. 475
Post-fire erosion control mulches alter belowground processes and nitrate reductase activity of a perennial forb, heartleaf arnica (Arnica cordifolia)

Four years post-wildfire, we measured soil and plant properties on hillslopes treated with two differ ent mulches (agricultural wheat straw and wood strands) and a control (unmulched, but burned). Soil total N was about 40% higher and microbial respiration of a standard wood substrate was nearly twice as high in the mulched plots compared to the unmulched plots. Greater respiration was tied to increased substrate moisture underneath mulch compared to bare soil. Nitrate reductase activity of a common forb (Arnica cordifolia) was about 30% higher on the wood strand plots than either the wheat straw or the unmulched plots. Mulch applications after wildfire may enhance N availability by increasing soil moisture, promoting microbial N mineralization, or by increasing biological nitrogen fixation. Because inference is limited for this case study, we call for additional replicated experiments investigating effects of mulch treatments on soil carbon and nitrogen cycling with links to plant regeneration.
The Place of the Etymon and the Phonetic Matrix in the Arabic Mental Lexicon

Two units have traditionally been proposed as the basis of the organization of the Arabic lexicon: the root and the stem. The root approach, the most common, is based on the root and pattern theory of Arabic morphology (e.g., McCarthy 1981), which contends that derivation is based on the interleaving of consonantal roots into patterns. By contrast, the stem approach is based on the stem-based theory of Arabic morphology (e.g., Benmamoun 1999) whose main tenet is that the stem is the basis of derivation. More recently, Bohas (e.g., 2000) has challenged these two approaches. He proposes that the Arabic lexicon is organized in three layers under three units: the phonetic matrix, the etymon, and the ‘radical’. These three proposals have different implications for the Arabic mental lexicon. This study discusses these theories with a focus on the validity of the notions of the etymon and matrix in the Arabic mental lexicon in light of old and new psycholinguistic evidence. Keywords : Arabic morphology, root, pattern, etymon, phonetic matrix, psycholinguistics, lexicon.
Rendering Techniques in 3D Computer Graphics Based on Changes in the Brightness of the Object Background

Maintaining accurate colour constancy and constant colour appearance are only a few challenges one must conquer in a modern day digital three‐dimensional (3D) production. Many different factors influence the reproduction of colour in 3D rendering and one of the most important is certainly rendering engines. In our research, we have studied rendering of colours with three rendering engines (Blender Render, Cycles and Yafaray) of an open source 3D creation suite based on changes in the brightness of the object background from 20 to 80%. In one of these cases, colour of the object was adapted to the lighter background using the colour appearance model CIECAM02. With the analysis of colour differences, lightness and chroma between colours rendered using different rendering engines; we found out that rendering engines differently interpret colour, although the RGB values of colours and scene parameters were the same. Differences were particularly evident when rendering engine Cycles was used. However, Cycles also takes into account the object background. Numerical results of such research provide findings, which relate to the respective environment, and also these certainly demonstrate the successful imple‐ mentation of the colour appearance model CIECAM02 in the 3D technologies and, in our opinion to other software packages for 3D computer graphics.
Body size increase in insular rodent populations: a role for predators?

Insular mammalian populations living in areas of small size are often characterized by a drastic change in body mass compared to related continental populations or species. Generally, small mammals (less than 100 g) evolve into giant forms while large mammals (up to 100 g) evolve into dwarf forms. These changes, coupled with changes in other life, behavioural, physiological or demographic traits are referred to generally as the insular syndrome. We tested in this study the relative contribution of three factors — area of island, numbers of competitor species and number of predator species — to changes in body size of the woodmouse ( Apodemus sylvaticus ) in the Western Mediterranean Sea. Our results, based on a comparative analysis using the phylogenetic independent contrasts method, indicate that the increase in body size is related both to the decrease of island size and to the lower number of predator species. A decrease of competitor species does not seem to have an important effect.
AmI-RIA: Real-Time Teacher Assistance Tool for an Ambient Intelligence Classroom

This paper discusses a learner-centric approach towards supporting instructors on improving the learning process in ambient educational environments. The proposed system introduces an intelligent multi-agent infrastructure that monitors unobtrusively the students' activities and notifies the teacher, in real-time, about potential learning weaknesses and pitfalls that need to be addressed. For that to be achieved several applications have been developed: (i) a real-time classroom activity visualizer, (ii) a behavioral reasoner that aims to identify common behaviors by analyzing classroom statistics records, and (iii) various mini-tools like the classroom attendance record, the schedule manager, etc. Following the system's description, findings of the preliminary expert-based evaluation are presented and future extensions are proposed.
Patient’s Clubs – underestimated support programmes

Purpose: The article aims to provide a comprehensive characterization of people with schizophrenia using the Patient’s Clubs, with particular consideration of the parameters of the healing process, such as social networks and the level of social relations. Methods: The study was completed in 2009-2011. It involved patients suffering from schizophrenia, who used the services of such Clubs. The control group were participants of other community treatment programs, who did not benefit from the Clubs. Data were collected, using the Sociodemographic Questionnaire, the Questionnaire of the course of Illness and the Questionnaire of Community Support System, prepared specially for this research, as well as the Bizoń Evaluation of Environmental and Social Support, the Birchwood Social Functioning Scale and the Scale of the General Mental Status Examination GAS. Results: In comparison with users of other programs, the Clubs participants use their services much longer, i.e. 83 months, on average. They have slightly more numerous social networks than those who do not participate in Clubs. The level of social functioning of patients was also examined. Those benefiting from the support of Clubs achieved higher results in scales ‘exiting isolation’ and ‘self-reliance implemented’. Significant part of the Clubs participants Clubs used at the same time other support programs, first of all the Occupational Therapy Workshops (26%) and the Environmental Self-Help Houses (39%). Conclusions: Participation in Clubs facilitates a stable and long-term support for people with mental illness experience. It is worth remembering that, when referring patients to such, the participants have great interpersonal potentials social resources to cope well with the symptoms of the disease. This may be an important form of support in returning to independent living. When creating or modifying the Clubs’ programs, we should emphasize on the access to activities associated with natural, and not only institutional forms of social life. Clubs may also become the basis for building a self-help movement of people with mental illness experience.
Representation of Parents and Children in Abuse and Neglect Cases: The Importance of Early Appointment

The serious consequences of abuse and neglect proceedings including placement in foster care and termination of parental rights mandate that parents and children receive competent and well-trained legal representation. Unrepresented parents and children cannot match the expertise and sophistication of government lawyers and trained child welfare workers in complex child abuse and neglect proceedings. To ensure a fair opportunity to present their positions, answer their questions, and guide them through a challenging legal, administrative, and emotional process, courts must provide trained and well-prepared legal counsel to parents and children. Counsel protects important constitutional and legal rights, helps prevent the unnecessary entry of children into foster care, and assists in strengthening family supports. Many state legislatures provide attorneys for parents in abuse and neglect cases, while some states provide for only discretionary appointment. In others, the appointment occurs late in the case at the adjudicatory or termination of parental rights hearing. Federal law mandates that the child have representation from a guardian ad litem (GAL)
LINKEDLAB: A DATA MANAGEMENT PLATFORM FOR RESEARCH COMMUNITIES USING LINKED DATA APPROACH

Data management has a key role on how we access, organize, and integrate data. Research community is one of the domain on which data is disseminated, e.g., projects, publications, and members.There is no well-established standard for doing so, and therefore the value of the data decreases, e.g. in terms of accessibility, discoverability, and reusability. LinkedLab proposes a platform to manage data for research communites using Linked Data technique. The use of Linked Data affords a more effective way to access, organize, and integrate the data. Manajemen data memilki peranan kunci dalam bagaimana kita mengakses, mengatur, dan mengintegrasikan data. Komunitas riset adalah salah satu domain dimana data disebarkan, contohnyadistribusi data dalam proyek, publikasi dan anggota. Tidak ada standar yang mengatur distribusi data selama ini.Oleh karena itu,value dari data cenderung menurun, contohnya dalam konteksaccessibility, discoverability, dan usability. LinkedLab merupakan sebuah usulanplatform untuk mengelola data untuk komunitas riset dengan menggunakan teknik Linked Data. Kegunaan Linked Data adalah sebuah cara yang efektif untuk mengakses, mengatur, dan mengitegrasikan data.
Effect of Monoethanolamine Loading on the Physicochemical Properties of Amine-Functionalized Si-MCM-41 (Kesan Penambahan Monoetanolamina terhadap Sifat Fiziko Kimia Si-MCM-41 Difungsikan oleh Amina)

Siliceous mesoporous molecular sieve (Si-MCM-41) material with highly ordered hexagonal pore arrangement was synthesized at 373 K for 8-days duration by hydrothermal method, dried at 393 K and calcined at 823 K in N 2 atmosphere. The calcined Si-MCM-41 was later functionalized with 10-50 wt. % monoethanolamine (MEA) by impregnation method and dried in vacuum at 343 K. The MEA-Si-MCM-41 samples were characterized for their physicochemical properties with FTIR, XRD, TGA, HRTEM, FESEM, BET and elemental analysis. XRD results showed that the intensity of the characteristic peaks of Si-MCM-41 reduces with increasing loading of MEA indicating that the MEA molecules are loaded in the pores as well as on the surface of Si-MCM-41. The appearance of FTIR peaks corresponding to N-H, C-N and C-H bonds suggested that Si-MCM-41 has been functionalized with MEA. The presence of Si-O-Si peaks in FTIR spectra of MEA-Si-MCM-41 samples indicates that the hexagonal pore arrangement remains intact and this is supported by HRTEM images. FESEM images show that MEA-Si-MCM-41 samples became agglomerated with increase loading of MEA. TGA analyses show that the MEA-Si-MCM-41 samples are thermally stable up to 528 K. N 2 adsorption-desorption isotherms show that the textural properties of Si-MCM-41 material slowly change from a mesoporous material to non-porous material as the MEA loading increases due to pore filling effect during functionalization with MEA. Detection of N, C and H by elemental analysis confirms the presence of MEA in MEA-Si-MCM-41 samples.
