Durability Analysis of Natural Lime Concrete

Concrete is known to be durable and dependable material since it is resistance to weathering action and chemical attacks while maintaining its engineering properties. However, carbon dioxide produced by the cement industries had caused severe environmental pollution. To minimize carbon dioxide emission into the atmosphere, eggshell wastes are treated as partial cement replacement in this study. The eggshell was oven-dried at 105.5 °C for 24 h before grinding it into powder passing through sieve size 45 µm. Eggshell powder was used as partial cement replacement at 5, 10, 15 and 20%. The performance of the concrete mix was evaluated against control concrete mix. The specimens were tested on acid attack and sulphate attack. The concrete specimens were prepared in the form of cubes and then subjected to water curing for 28 days before immersed in sulphuric acid solution for 1800 h and sodium sulphate for 50 weeks respectively. From the analysis, it is observed that reduction of compressive strength of the concrete cubes for the acid attack and sulphate attack reduce gradually when the eggshell powder increase
Kava and ethno-cultural identity in Oceania

Garibaldi and Turner (Ecol Soc 9:1, 5, 2004) explain the role that particular plants play in facilitating the shared ancestry, practices, and social experience of an ethnicity. This can include spiritual connections, cultural expression and practice, ceremony, exchange, linguistic reflection, socialization, and medicinal and/or dietary systems. They term these plants “cultural keystone species” and icons of identity, plants that if removed would cause some disruptions to the cultural practices and identity of an ethnic group. Undoubtedly, kava (Piper methysticum) is the cultural keystone species for many Oceanic and Pacific peoples, a “differentiating element of common culture” (Zagefka, Ethnicity, concepts of. In: Smith AD, Hou X, Stone J, Dennis R, Rizova P (eds) The Wiley Blackwell encyclopedia of race, ethnicity, and nationalism. West Wiley, Sussex, pp 761–763, 2016) informing their ethno-cultural identity. That influence is also extending to new non-Pacific Island user groups who have embraced elements of kava ethno-cultural identity in what has been termed diasporic identity formation in reverse. This chapter will discuss kava with specific reference to ethnic positionality in Fiji while recognizing the tensions from inside and outside the region that support and threaten the continuance of the kava drinking tradition
Trust and food modernity in Vietnam

The authors detail the deep transformation of the Vietnamese food system during the last decades, in relation with the industrialization of food production and the extension of the food market chains. The consequences are a growing food anxiety among consumers and an evolution in the process of trust building: the urban consumers still rely on their own know-how to keep their home as a safe place to eat as well as on their day-to-day personal relations with their usual retailers. But trust building has also evolved to include the trust in some stakeholders such as supermarkets rather than in public control. This diversity in the ways of building trust in food can be seen as a characteristic of modernity in emerging Asian economies
Scattering Theory and $\mathcal{P}\mathcal{T}$-Symmetry

We outline a global approach to scattering theory in one dimension that
allows for the description of a large class of scattering systems and their
$\mathcal{P}$-, $\mathcal{T}$-, and $\mathcal{P}\mathcal{T}$-symmetries. In
particular, we review various relevant concepts such as Jost solutions,
transfer and scattering matrices, reciprocity principle, unidirectional
reflection and invisibility, and spectral singularities. We discuss in some
detail the mathematical conditions that imply or forbid reciprocal
transmission, reciprocal reflection, and the presence of spectral singularities
and their time-reversal. We also derive generalized unitarity relations for
time-reversal-invariant and $\mathcal{P}\mathcal{T}$-symmetric scattering
systems, and explore the consequences of breaking them. The results reported
here apply to the scattering systems defined by a real or complex local
potential as well as those determined by energy-dependent potentials, nonlocal
potentials, and general point interactions.Comment: Slightly expanded revised version, 38 page
Holomorphic embeddings and immersions of Stein manifolds: a survey

In this paper we survey results on the existence of holomorphic embeddings
and immersions of Stein manifolds into complex manifolds. Most results pertain
to proper maps into Stein manifolds. We include a new result saying that every
continuous map $X\to Y$ between Stein manifolds is homotopic to a proper
holomorphic embedding provided that $\mathrm{dim} Y > 2\mathrm{dim}\, X$ and we
allow a homotopic deformation of the Stein structure on $X$.Comment: To appear in: J. Byun et al. (eds.), Geometric Complex Analysis

Wireless EEG signal transmission using\ud
visible light optical camera communication

Electroencephalogram (EEG) has been widely adopted for the brain monitoring. The transmission of the EEG signals captured from the scalp using electrodes to a displayed screen is often performed through wires utilizing Radio\ud
Frequency (RF) communication technology. The wired EEG transmission restricts the patient movement during the entire EEG recordings. However, patient movement is necessary during EEG recordings in certain medical scenario.\ud
Towards this end, wireless transmission of the EEG signals enables patient movements during the recordings. In this context, this paper proposes a Visible Light Optical Camera Communication (VL-OCC) system for wireless transmission of EEG signal. The signal transmission under the LOS, line of sight is conducted modulation scheme namely On-Off-Keying (OOK), Non-Return-to-Zero (NRZ). Specifically, organic light emitting diode, and optical camera are used as sender and receiver in the system, respectively. The performance of VLOCC system is evaluated by developing an experimental prototype under realistic medical scenario.\ud

The global formulation of generalized Einstein-Scalar-Maxwell theories

We summarize the global geometric formulation of Einstein-Scalar-Maxwell
theories twisted by flat symplectic vector bundle which encodes the duality
structure of the theory. We describe the scalar-electromagnetic symmetry group
of such models, which consists of flat unbased symplectic automorphisms of the
flat symplectic vector bundle lifting those isometries of the scalar manifold
which preserve the scalar potential. The Dirac quantization condition for such
models involves a local system of integral symplectic spaces, giving rise to a
bundle of polarized Abelian varieties equipped with a symplectic flat
connection, which is defined over the scalar manifold of the theory.
Generalized Einstein-Scalar-Maxwell models arise as the bosonic sector of the
effective theory of string/M-theory compactifications to four-dimensions, and
they are characterized by having non-trivial solutions of "U-fold" type.Comment: 10 pages. Summary of the main results of reference arXiv:1609.05872

SU(2), Associated Laguerre Polynomials and Rigged Hilbert Spaces

Producción CientíficaWe present a family of unitary irreducible representations of SU(2) realized in the plane, in terms of the associated Laguerre polynomials. These functions are similar to the spherical harmonics defined on the sphere. Relations with a space of square integrable functions defined on the plane, L2(R2), are analyzed. We have also enlarged this study using rigged Hilbert spaces that allow to work with discrete and continuous bases like is the case here.Ministerio de Economía, Industria y Competitividad ( (Project MTM2014-57129-C2-1-P)Junta de Castilla y León (programa de apoyo a proyectos de investigación - Ref.

Prediction of Structures and Interactions from Genome Information

Predicting three dimensional residue-residue contacts from evolutionary
information in protein sequences was attempted already in the early 1990s.
However, contact prediction accuracies of methods evaluated in CASP experiments
before CASP11 remained quite low, typically with $<20$% true positives.
Recently, contact prediction has been significantly improved to the level that
an accurate three dimensional model of a large protein can be generated on the
basis of predicted contacts. This improvement was attained by disentangling
direct from indirect correlations in amino acid covariations or cosubstitutions
between sites in protein evolution. Here, we review statistical methods for
extracting causative correlations and various approaches to describe protein
structure, complex, and flexibility based on predicted contacts.Comment: 35 pages, 4 Tables, and 1 figures. In 2018, this manuscript with the

Dynamics and statistics in the operator algebra of quantum mechanics

Physics explains the laws of motion that govern the time evolution of
observable properties and the dynamical response of systems to various
interactions. However, quantum theory separates the observable part of physics
from the unobservable time evolution by introducing mathematical objects that
are only loosely connected to the actual physics by statistical concepts and
cannot be explained by any conventional sets of events. Here, I examine the
relation between statistics and dynamics in quantum theory and point out that
the Hilbert space formalism can be understood as a theory of ergodic
randomization, where the deterministic laws of motion define probabilities
according to a randomization of the dynamics that occurs in the processes of
state preparation and measurement.Comment: 10 pages, contribution to the proceedings of the Nagoya Winter

Reverse Data-Processing Theorems and Computational Second Laws

Drawing on an analogy with the second law of thermodynamics for adiabatically
isolated systems, Cover argued that data-processing inequalities may be seen as
second laws for "computationally isolated systems," namely, systems evolving
without an external memory. Here we develop Cover's idea in two ways: on the
one hand, we clarify its meaning and formulate it in a general framework able
to describe both classical and quantum systems. On the other hand, we prove
that also the reverse holds: the validity of data-processing inequalities is
not only necessary, but also sufficient to conclude that a system is
computationally isolated. This constitutes an information-theoretic analogue of
Lieb's and Yngvason's entropy principle. We finally speculate about the
possibility of employing Maxwell's demon to show that adiabaticity and
memorylessness are in fact connected in a deeper way than what the formal
analogy proposed here prima facie seems to suggest.Comment: ver2: discussions clarified, typos corrected, references added, and

Trust-free verification of steering: why you can't cheat a quantum
  referee

It was believed until recently that the verification of quantum entanglement
and quantum steering, between two parties, required trust in at least one of
the parties and their devices, in contrast to the verification of Bell
nonseparability. It has since been shown that this is not the case: the need
for trust, in verifying two parties share a given quantum correlation resource,
can be replaced by quantum refereeing, in which the referee sends quantum
signals rather than classical signals to untrusted parties. The existence of
such quantum-refereed games is discussed, with particular emphasis on how they
make it impossible for the parties to cheat. The example of a particular
quantum-refereed steering game is used to show explicitly how
measurement-device independence is achieved via `quantum programming' of
untrusted measurement devices; how cheating is prevented by the steered party
being unable to distinguish sufficiently well between two sets of nonorthogonal
signal states; and that cheating remains impossible when one-way communication
is allowed from the steered party to the unsteered party. This game has been
recently implemented experimentally, and is of particular interest both in
accounting for any imperfections in the referee's preparation of signal states,
and in suggesting the future possibility of secure two-sided quantum key
distribution with Bell-local states.Comment: Submitted to Proceedings of the Nagoya Winter Workshop 2015

Pivot machine translation using Chinese as pivot\ud
language

Pivoting through a popular language with more parallel corpora available (e.g. English and Chinese) is a common approach to build machine translation\ud
(MT) systems for low-resource languages. For example, to build a Russian-to Spanish MT system, we could build one system using the Russian–Spanish corpus\ud
directly. We could also build two systems, Russian-to-English and English-to Spanish, as the resources of the two language pairs are much larger than the\ud
Russian–Spanish pair, and use them cascadingly to translate texts in Russian\ud
into Spanish by pivoting through English. There are, however, some confusing\ud
results on the Pivot MT approach in the literature. In this paper, we reviewed the\ud
performance of Pivot MT with the United Nations Parallel Corpus v1.0 (UN6Way)\ud
using both English and Chinese as pivot languages. We also report our system\ud
performance on the CWMT 2018 Pivot MT shared task, where Japanese patent\ud
sentences are translated into English using Chinese as the pivot language
The Ethno-Cultural Influences on “Assam Type” Building Typology—A Case of Barduwa, Assam

Assam has peculiar geographical and climatic conditions; which has shaped its culture, practices and vernacular style. We see direct influences of such features on society which has remained self-sufficient for centuries and their reflections in ethnic styles in food habits, clothing, agriculture, fisheries, architecture, beliefs, recreation, etc. Objective of this research is to conduct studies on ethno-cultural influence mapping in evolution of vernacular architecture. Study was conducted to find existing conditions in various domains of public life, aspirations, occupational activities, supporting infrastructure, for system analysis and intervening areas which can maintain idea of sustainability around local building designs. Study resulted in identification of Acts, Actors and their Inter-relationships which are crucial for evolution of such typology and socio-cultural system. Design Directions on four perspectives are drawn
A Critical Study of Choke Point in Sustainable Recycling of Household Waste in an Assamese Village Setting

Stigma around consumable products and impact on local sustainability has led us to choke point. Paper examines household waste disposal into a small pond called Pukhri. After certain intervals, the pond would be dredged out to clean up the pond, which subsequently ended in agricultural fields. Today, other household waste items including material constituting laminated papers, plastics, inorganic waste etc., are being dumped into Pukhri. In order to establish a familiarity with situation, paper discusses imperative need for new order of waste management in village through data assessment and analysis and finding relations between actors, activities, and dependent phenomenon for a sustainable waste management system. It was found that levels of interconnections between various actors are facing blockage and impacts on domestic fowls, fish, and cattle were noticed. The paper elaborates on vernacular system, change in the system and impacts over stakeholders, etc
The impact of mfinance initiatives in the global south: a review of the literature

After more than two decades of research on technological interventions in the transition to information societies, the burgeoning of mobile phones in developing countries has shifted the information and communication technologies for development (ICT4D) research lens to the different domains of mDevelopment. While advances have been made in domains of mHealth, mGovernment, mBusiness and mEducation, mFinance initiatives have had impressive adoption upon implementation in certain geographic locations. Services such as M-Pesa have been widely reported in the mainstream press and form the test beds for various scholarly investigations.Indexado en Scopu
Teacher judgement and the challenges of moderation

Moderation, or social moderation involves teachers meeting together to discuss and negotiate judgments made on student work. It is discussed in a holistic sense of encompassing all stages of the teaching/learning process. In systems that employ standards-referenced curriculum and assessment, social moderation and/or online moderation are processes adopted to ensure consistency and reliability of assessment grades. Moderation is a social practice in which teachers present and critique judgment decisions based on critical evidence in the sample or portfolio of work. Teachers willingly open their practice to scrutiny from colleagues and respond to feedback on judgment decisions. Moderation is discussed and analyzed in terms of the various ways it may be organized and the key processes involved. Challenges to moderation include the subjectivity of judgment making; the lack of engagement with the standard; the interplay of identity and differential power relations in judgment making and critique of judgments; and the difficulty of achieving consistency across an entire education system. Moderation represents a form of professional learning when teachers critically reflect on their understanding of the standard and develop goals to improve their future instruction and assessment practices
Kaitiakitanga - Active guardianship, responsibilities and relationships with the world: Towards a bio-cultural future In early childhood education

The world is a vast family, and humans are children of the earth and sky, and cousins to all living things. Such unity means that nature is the ultimate teacher about life (Royal 2010, p. 9).
For Māori (indigenous peoples of Aotearoa New Zealand) the term kaitiakitanga (pronounced, kye-tee-ah-key-tar-ngah) is often used to refer to the active guardianship and management of natural organisms and their environments. Mātauranga Māori or Māori knowledge positions humans within nature and focuses on ways in which cultural understandings and intergenerational connections between people and their biophysical contexts assist in the retention and protection of biodiversity and ecologically sustainable ecosystems. This entry critically reflects notions of kaitiakitanga and bio-cultural connectivity as important and meaningful contributors for young children and their relationships with and for the world
Afterschool media club: Critical literacy in a high-diversity, high-poverty urban setting

In this chapter, we look at critical literacy at MediaClub, a programme of afterschool media production activities for 9- to 12-year-olds. MediaClub was part of the URLearning (URL) research project (2010–2014), which was conducted in a high-diversity, high-poverty elementary school in the state of Queensland, Australia. The Club was designed to skill interested young people up as digital media experts for the literate practices of their homes, communities and classrooms. We anticipated that it would be a space where the receptive and expressive dimensions of critical literacy flourished. Here we look at what happened in practice, drawing implications for literacy education at a time of increasingly prescriptive, if not scripted, pedagogies.Full Tex
Innovative Learning Design for Online Language Learning: A Systems Design Framework

With the demand for access to diverse modes of learning, this chapter focuses on how online Chinese language learning can be effectively designed to maximize learning outcomes. As teaching and learning a second language in a fully online mode is a new and rapidly evolving process, there are many challenges facing language professionals. Online language learning in this research refers to learning conducted fully online, in which learners are separated from education providers and their peers by distance.

This research first proposes a framework for online language learning design based on established instructional design models, a systems approach to learning design, and language learning theories. The proposed framework addresses six basic elements in online learning design, namely, the analysis of learners, the assessment of technological affordances, course design, learning support design, ongoing reflection and evaluation, and continuous improvement. A systems approach is adopted to emphasize the inter-relationship between the six elements which interact to constantly improve learning outcomes. This framework is then evaluated using the learning design built into a fully online Chinese program offered at Griffith University in Australia, as a case study. The evaluation indicates that the proposed framework is effective in capturing the essential design elements in online language learning, and more importantly, in promoting the inter-connection and interaction between these elements which constantly interact with each other to form an iterative cycle of analysis, design, evaluation and improvement. It is expected that this research will advance our understanding of the optimal design for online language learning in particular and the potential of online language learning as a whole.Arts, Education & Law Group, School of Languages and LinguisticsFull Tex
Commentary on 'Competencies'

In reading the editors’ introduction and these interesting and informative accounts of how skills and competencies are learned and taught under the umbrella of the Singaporean quadrilingual language policy in which everyone is to learn English and their respective mother tongue, it is interesting to compare the Singaporean policy with the trilingual–biliterate language education policy of Hong Kong, where the government’s aim is to ensure its citizens are trilingual in Cantonese, Putonghua Mandarin and English and biliterate in Chinese and English.Arts, Education & Law Group, School of Languages and LinguisticsFull Tex
